In general, referring to
The vehicle platform 1 may be any vehicle or vehicle-like apparatus suitable for traversing the tillage assembly 2 across an aquaculture site or other mollusc harvesting site in order to harvest the molluscs contained therein by agitating and sifting the dirt of the harvesting site in order to expose and collect the molluscs. In some embodiments, the vehicle platform 1 is a tractor. In some embodiments, the vehicle platform 1 is a tractor-like vehicular assembly.
The tillage assembly 2 is connected to the vehicle platform 1 by the support frame 3. The agitating mechanism 4 is operatively connected to the tillage assembly 2. More particularly, the agitating mechanism 4 is operatively connected between the support frame 3 and the tillage assembly 2 in some embodiments. In some embodiments, the agitating mechanism 4 is operatively connected between the vehicle platform 1 and the tillage assembly 2. The agitating mechanism 4 functions to shake the tillage assembly 2 in order to till the earth traversed by the vehicle platform 1 while the present invention is in use. Agitation of the tillage assembly 2 serves to separate and sift out any dirt, small rocks, plant matter, or other unwanted items from the molluscs desired to be harvested.
The tillage assembly 2 is connected to the vehicle platform 1 by the support frame 3 and comprises a tilling section 21. In some embodiments, the tillage assembly 2 may be connected directly to the vehicle platform 1. It may be understood that the support frame 3 refers to any structural members implemented to support the tillage assembly 2 and agitating mechanism 4 with the vehicle platform 1 in order to perform their proper function. In some embodiments, the support frame 3 may be integrated with the vehicle platform 1. In some embodiment, the support frame 3 may be pulled behind the vehicle platform 1 like a trailer.
The tilling section 21 is the main component of the present invention for sifting molluscs from the earth and other debris of the harvesting site. In the preferred embodiment, the tilling section 21 is generally flat and rectangular, though the tilling section 21 may have varying geometry in different embodiments. The angling mechanism 5 is operatively connected to the tilling section 21, wherein the angling mechanism 5 is configured to adjust a pitch angle of the tilling section 21. The pitch angle of the tilling section 21 may be lowered toward the ground in order to harvest molluscs or raised away from the ground in order to traverse the ground without performing the harvesting function of the present invention, or the pitch angle may be adjusted by the user in order to achieve a proper tilling angle into the ground for optimal harvesting. Tilling herein refers to the action of disturbing the soil, earth, or ground of the mollusc harvesting site in order to expose the molluscs shallowly buried within the said earth.
The tilling section 21 comprises a plurality of sifting rods 22 that are laterally distributed along the tilling section 21 and oriented longitudinally. The longitudinal direction used herein refers to the direction of the vehicle platform 1 while traveling straight. A lateral direction is correspondingly defined as perpendicular to the longitudinal direction and parallel to the ground, or east-west, if the longitudinal direction is alternatively defined as north-south in reference to the vehicle platform 1 (not the cardinal directions of the planet). The sifting rods are evenly spaced along the tilling section 21, leaving spaces through which the earth, rocks, plant matter and other debris of the harvesting site along with small molluscs may fall through due to the agitation implemented by the agitation mechanism, retaining and exposing any properly sized molluscs contained within the tilled earth. The agitating mechanism 4 is configured to longitudinally agitate the plurality of sifting rods 22. This agitation facilitates the purpose of disturbing the earth in addition to sifting the earth and other unwanted debris through the spaces between the plurality of sifting rods 22 of the tilling section 21. In the preferred embodiment, the angling mechanism 5 comprises a hydraulic actuator 6 connected between the vehicle platform 1 and the support frame 3. In various embodiments, the angling mechanism 5 may take any suitable form to achieve the aforementioned purpose.

In the preferred embodiment, the tillage assembly 2 further comprises a sifting section 23. The sifting section 23 is positioned longitudinally adjacent to the tilling section 21. Similar to the tilling section 21, the sifting section 23 further comprises a plurality of sifting rods 22 that are laterally distributed along the sifting section 23 and oriented longitudinally. The sifting section 23 essentially extends the available sifting area of the tillage assembly 2 rearward along the support frame 3. In the preferred embodiment, the sifting section 23 and the tilling section 21 are not directly connected to each other and are agitated independently with the agitation mechanism. This is desirable so that the pitch angle of the tilling section 21 may be adjusted without changing the angle of the entire tillage assembly 2.
In the preferred embodiment, the tillage assembly 2 is supported beneath the vehicle platform 1 adjacent to the earth by the support frame 3. Furthermore, while the support frame 3 is rigidly fixed to the vehicle platform 1, the tillage assembly 2 is moveable with reference to the vehicle platform 1 in order to permit the desired agitation motion of the tillage assembly 2. To this end, the present invention comprises at least one tilling section support member 7 through which the tilling section 21 is rotatably mounted to the support frame 3. The aforementioned rotatably mounted connection of the tilling section 21 to the support frame 3 through the at least one tilling section support member 7 allows the tilling section 21 to undergo the desired agitation motion. The rotational nature of said connection is due to a rotatable connection, such as a pin or hinge, of the at least one tilling section support member 7 to the support frame 3, and a similar connection between the at least one tilling section support member 7 and the tilling section 21. In other embodiments, other mechanical connections may be utilized in order to allow the agitation motion, such as, but not limited to, a linear track connection, or any other suitable type of connection.
More particularly, in the preferred embodiment the at least one tilling section support member 7 comprises a first tilling section support member 71 and a second tilling section support member 72. The first tilling section support member 71 and the second tilling section support member 72 are positioned laterally opposite each other along the tilling section 21. The first tilling section support member 71 is connected between the tilling section 21 and the first lateral side 33 of the support frame 3 in the preferred embodiment. Similarly, the second tilling section support member 72 is connected between the tilling section 21 and the second lateral side 34 of the support frame 3 in the preferred embodiment. In other embodiments, any other suitable arrangements may be comprised to connect the tilling section 21 to the support frame 3.
Similarly, the preferred embodiment further comprises at least one sifting section support member 8, and the sifting section 23 of the tillage assembly 2 is rotatably mounted to the support frame 3 through the at least one sifting section support member 8.
More particularly, the at least one sifting section support member 8 comprises a first sifting section support member 81 and a second sifting section support member 82. The first sifting section support member 81 and the second sifting section support member 82 are positioned laterally opposite each other along the sifting section 23. The first sifting section support member 81 is connected between the sifting section 23 and the first lateral side 33 of the support frame 3, while the second sifting section support member 82 is connected between the sifting section 23 and the second lateral side 34 of the support frame 3. In other embodiments, any other suitable arrangements or geometries may be utilized in order to support the tillage assembly 2 at the proper height above the ground while allowing the desired agitation motion.
Referring to
The specific means through which the plurality of rods is coupled to the plurality of cams 43 in order to produce the agitating motion may vary in different embodiments. However, in the preferred embodiment, a plurality of annular sheaths 9 is utilized, as shown in
In the preferred embodiment, the plurality of agitating rods 44 comprises a first pair of agitating rods 45 and a second pair of agitating rods 46 as shown in
Moreover, the tillage assembly 2 further comprises a first transfer member 24 and a second transfer member 25. The first transfer member 24 is connected to the tilling section 21, and the second transfer member 25 is connected to the sifting section 23. Preferably, the first transfer member 24 is oriented laterally and connected between the first sifting section support member 81 and the second sifting section support member 82, though the specific location of the transfer member may vary in different embodiments. Similarly, the second transfer member 25 is preferably oriented laterally and connected between the first sifting section support member 81 and the second sifting section support member 82. The first pair of agitating rods 45 is connected between the axle 41 and the first transfer member 24, and the second pair of agitating rods 46 is connected between the axle 41 and the second transfer member 25. Thus, the tilling section 21 and the sifting section 23 of the tillage assembly 2 may be agitated independently of each other. Furthermore, in some embodiments, the first pair of agitating rods 45 is connected to a first pair of cams at the axle 41, while the second pair of agitating rods 46 is connected to a second pair of cams at the axle 41. In some embodiments, the first pair of cams and the second pair of cams may be radially oriented out of phase with each other by a desired angle; for example, 180 degrees. Thus, in embodiments where the first pair of cams and the second pair of cams are oriented 180 degrees out of phase with each other, with each rotation of the axle 41, the tilling section 21 and the sifting section 23 move in opposite longitudinal directions during agitation. This may enhance the sifting effect of the tilling assembly. However, the alignment of the cams may vary as desired in various embodiments.
