Description

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates to a method and apparatus for broadcasting pregerminated seed plantlets uniformly over a wide area of preprepared ground. In particular the present invention relates to an apparatus wherein the pumping system does not damage the plantlets as they are being broadcast.

(2) Prior Art

Hydroseeding is well known. In this method the seeds along with various fibers or the like are broadcast onto the ground. Generally the seeds and fibers are deposited on the ground together Illustrative prior art are U.S. Pat. Nos. 2,789,399; 2,842,897; 2,878,617; 3,091,436 to Finn; and 3,292,307 and 4,297,810 to Hansford. The problem is that the seeds may not germinate after planting.

U.S. Pat. Nos. 3,900,963 to Tukacs 4,155,314 to O'Callaghan et al, 4,631,860 to Broughton and 4,658,539 to Sluis describes numerous advantages obtained from the sowing of pregerminated seeds. The problem has been that an apparatus for sowing plantlets produced from the pregerminated seeds without damage during the planting has not been available.

Pregerminated seed plantlets are very fragile and are easily destroyed by apparatus including conventional pumps with impellors. Thus, there is a need for apparatus to make the planting of pregerminated seed plantlets practical.

U.S. Pat. No. 4,224,882 to Cruse shows a coulter apparatus for planting seeds in a furrow. The apparatus is not designed for general planting of plantlets uniformly over a wide area of preprepared ground and the apparatus was not designed for planting plantlets.

OBJECTS

It is therefore an object of the present invention to provide an apparatus and method for dispersing pregerminated seed plantlets over a wide area without damaging the fragile plantlets. Further, it is an object of the present invention to provide an apparatus which is simple and economical to construct. Further still, it is an object of the present invention to provide an apparatus and method which are easy to use. These and other objects will become increasingly apparent by reference to the following description and the drawings.

SPECIFIC DESCRIPTION

FIGS. 1 to 5 show the preferred apparatus 10 of the present invention for delivering the pregerminated seed plantlets onto the ground. FIG. 6 shows a schematic of the apparatus of FIGS. 1 to 5. FIG. 7 shows an improved version of the apparatus of FIG. 6.

Referring to FIGS. 1 to 4, an apparatus 10 is mounted on a truck bed 100 or other mobile trailer. An open frame 11 is mounted on the truck bed 100. The frame 11 has a rectangular base 11a, vertical posts 11b, 11c, 11d and 11e and a top 11f mounted on the posts 11b to 11e. Brace 11g aids in holding the frame 11 on bed 100. A tank 12, containing the pregerminated seed plantlets in an aqueous solution 101, is also mounted on the truck bed 100 with the frame 11 adjacent to one end 12a of the tank 12. The tank 12 includes a cover 12b (FIG. 6) for providing the pregerminated seed composition in the tank 12. Cradle 100a (FIG. 2) mounted on bed 100 holds tank 12 in place on bed 100. The pumping and mixing system described hereinafter for the pregerminated seed plantlet dispersion is mounted on the frame 11.

A gasoline engine 13 is mounted on the base 11a. The engine 13 is coupled through shaft 13a by means of universal joint 14 to shaft 15a (FIGS. 4 and 7) of a hydraulic pump 15. A housing 15b surrounds shafts 13a and 15a and joint 14. In series in hydraulic lines 16, 17 and 18 with pump 15 (FIG. 6) are a hydraulic reservoir 19 and a manifold 20 with three levers 20a, 20b and 20c controlling separate conventional internal two-way hydraulic valves (not shown) inside the manifold 20.

Hydraulic hoses 21 and 22 are connected to a hydraulic motor 23 and to manifold 20 and controlled by lever 20a. The motor 23 is mounted on the top 11f of the frame 11 adjacent tank 12. A shaft 24 is connected to the motor 23 and is mounted in rotationally sealed relationship by means of seal 12c (FIG. 2) through the end 12a of tank 12. An agitator 25 is mounted on shaft 24, such that the pregerminated seed plantlet dispersion can be gently mixed.

Lever 20b controls hoses 26 and 27 leading to a hydraulic motor 28 which is connected by means of shaft 28a and coupling 29 to a peristaltic pump 30 through rotatable pump shaft 30a (FIG. 1). The pump 30 is mounted on a support 32 including vertical mounts 33 braced by angle members 34. The motor 28 is mounted on support 32 by means of angle member 35.

Lever 20c controls hoses 36 and 37 leading to hydraulic motor 38 mounted on brackets 39 and 40. The shaft 38a on motor 38 rotates around axis a--a. A reel 41 connected to the shaft 38a (FIGS. 6 and 7) is mounted to rotate on axis a--a between the brackets 39 and 40 and dispenses hose 42 when the reel 41 is rotated by shaft 38a through universal joint 46. At the distal end of hose 41 (FIG. 6), a nozzle 43 is provided with an angled plate 44 over opening 43a for gently dispersing the pregerminated seed plantlet dispersion 102 onto the ground. Pipe 43b is connected to coupling 43c. From the center of the reel 41 along axis a--a, a hose section 45b is provided leading to peristaltic pump 30 which is connected to hose 42 through reel 41. The pump preferably operates up to about 100 psi so as not to damage the seeds. A hose section 45a leads from pump 30 to the bottom of tank 12. FIG. 5 shows that hose sections 45a and 45b are connected to a section 45c inside pump 30. The number 45 designates all of the hose sections 45a, 45b and 45c.

As particularly shown in FIG. 3, levers 20a, 20b and 20c are pivoted on pins 20d, 20e and 20f and are connected to valve shafts 20g, 20h and 20by pins 20j, 20k and 201. Holders 20m, 20n and 20o are mounted on manifold 20 to hold pins 20d, 20e and 20f. Needle valve 20p is used to shut off the flow of hydraulic fluid in the manifold 20.

As shown in FIGS. 1 and 2, the engine 13 is fed with gas from tank 47 by line 48. The engine 13 includes a muffler 49 for exhaust. The engine 13 is provided with an on-off ignition switch 50, a starter button 51 and a throttle 13a.

As shown in FIG. 2, the hydraulic reservoir 19 is provided with a valve 52 and a hose 53 connected to pump 15 for regulating the hydraulic pressure in the pump 15. A filter 54 is provided in series in the line 17 for removal of foreign matter from the hydraulic fluid. Pressure gauge 19b measures the pressure in hose 53. Reservoir 19 is mounted on support 19c secured to bed 100.

The pump 23 is mounted on bracket 55 on the top 11f of frame 11. Shaft 23a of the pump 23 is connected to shaft 24 by means of the universal joint 57.

FIG. 5 shows a cross-section of the peristaltic pump 30 along line 5--5 of FIG. 1. Shaft 31 of pump 30 supports a disc 58 inside housing 59 which rotates with shaft 30a. Opposed hose compression rollers 60 and 61 compress hose section 45c connected at opposed ends to couplings 59a and 59b of pump 30. As can be seen rollers 60 and 61 compress the hose at points 45d and 45e so that the hose section 45c containing the pregerminated seed is moved to hose section 45b. The peristaltic pump 58 is very important to the present invention since it can pump the plantlets without destroying them. The pump 30 is provided with a mounting flange 62 with holes 63 for securing the pump 30 to the bottom 11a of the frame 11.

FIG. 7 shows a variation of the present invention which is identical to FIG. 6 except that a pressure switch 70 is provided in hose section 45b of hose 45. The switch 70 is connected to electric clutch 71. Universal joints 72 and 73 are provided on opposed ends of the shaft 74 of the clutch 71. One end of the shaft 74 is connected to hydraulic motor shaft 28a. The hose 42 is provided with a ball valve 75 and a pipe 76 supporting nozzle 43b and angled plate 44a.

Referring to FIGS. 1 to 6, the pregerminated seed plantlet dispersion 101 is introduced into tank 12 by removing cover 12a. Motor 13 is started which pressurizes the flow of hydraulic fluid through the manifold 20. Lever 20a is moved to actuate motor 23 and agitator 25. Lever 20c is moved to dispense hose from reel 41. When the operator is ready to broadcast the plantlets, lever 20b is actuated, usually by a second operator, and the pregerminated seed plantlet dispersion 102 is broadcast from opening 43a of nozzle 43 onto the ground.

Referring to FIG. 7, the operator opens ball valve 75 to allow the pregerminated seed solution to be broadcast onto the ground from opening 43c of nozzle 43b. When the ball valve 75 is closed, the pressure in hose section 45 increases so that pressure switch 70 activates clutch 71 to disengage the motor 28 from the pump 30. This stops the rotation of the disk 58 and rollers 60 and 61 (FIG. 5) thus preventing the plantlets from being crushed when the dispersion 102 is not flowing from the nozzle 43b.

It will be appreciated that the hydraulic system preferably operates the motors 23, 28 and 38 in a forward or in reverse direction. This merely requires a two-way valve (not shown) which reverses the flow of hydraulic fluid to the motors 23, 28 and 38.

The preferred dispersion 102 is set forth as follows in Table I.
