Claims
- 1. An apparatus for mixing into a ground layer a ground stabilizing material in solid or liquid form, said apparatus comprising:
- a carrier,
- means for moving said carrier in an endless path above the ground surface,
- said carrier including a number of material injecting members,
- a storage container carrying ground stabilizing material,
- means for transferring said material from said storage container to said material injecting members, the improvement wherein:
- said means for moving said carrier in an endless path above the ground surface comprises means for moving said material injecting members in a substantially linear portion of the endless path across the travelling direction of the vehicle,
- means for agitating the material injecting members during its passage, and
- means for variably proportioning material at its departure from the material injecting members.
- 2. An apparatus as claimed in claim 1, characterized in that at least one agitating and one proportioning means are mounted on a rotatable vertical shaft (11, 11a) in the material injecting members (5).
- 3. An apparatus as claimed in claim 2, wherein the proportioning means comprises a propeller-like element with adjustable pitch.
- 4. An apparatus as claimed in claim 1, characterized in that the vertical shaft is caused to rotate via a preferably circular element at the upper end of the material injecting members, the element engaging against and rolling against a track along the travelling path of the material injecting members.
- 5. An apparatus as claimed in claim 4, characterized in that the relative distance between the element and the track is adjustable for varying the rotational speed.
- 6. An apparatus as claimed in claim 4, characterized in that the element consists of an inflatable rubber wheel at variable pressure.
- 7. An apparatus as claimed in claim 4, wherein the element is mounted on a rotatable hopper-shaped filling portion in the upper end of the material injecting member.
- 8. An apparatus as claimed in claim 1, wherein the material injecting members have a lower administrating member with at least two vertical slots of adjustable aperture size.
- 9. An apparatus as claimed in claim 1, wherein a rotatable disk is provided in the region of the curved portion of the track between the storage container and the upper portion of the material injecting members, said disk having a number of holes falling into alignment with the upper portion of the material injecting members, said holes having a diameter corresponding to the inside diameter of said upper portions, and means for driving said disks at a speed such that the centers of the holes move together with the centers of the material injecting members.
