It comprises a fixing means 4 for fixing the body frame 3 at a position, a hopper 5 which constitutes a compost supply means together with a cutout means, and a punching machine indicated by reference numeral 6 as a whole.
The illustrated body frame 3 is of a wheelbarrow type, but may be provided with a power unit and run on its own.

  As shown in FIG. 2, the rear wheel 2 is supported by an inner pipe 9 having a double pipe structure including an outer pipe 8 attached to the vehicle body frame 3 and an inner pipe 9 slidably inserted into the outer pipe 8. The inner tube 9 has a nut 12 screwed to a ball screw 11 that is rotatably supported on the outer tube 8 only by rotating a handle 13 fixed to the shaft end of the ball screw 11. It moves up and down together with the rear wheel 2.

  The fixing means 4 is supported by the front and rear of the vehicle body frame 3 so as to be able to move up and down, is lifted and lowered by loosening a set screw 14, and is composed of a pile-shaped rod 15 fixed by tightening the set screw 14. The body frame 3 can be fixed by loosening the rod 14 and driving the rod 15 into the ground.

  The hopper 5 is filled with compost, and a gate (not shown) serving as a cutout means provided at the outlet is opened and closed to supply the compost via a chute 17 to a hole drilled on the ground by the drilling machine 6. It has become.

  The boring machine 6 includes an outer cylinder 21 attached to the vehicle body frame 3, an inner cylinder 22 inserted into the outer cylinder 21, and two cylinders 21 and 22 between the outer cylinder 21 and the inner cylinder 22, respectively. An intermediate cylinder 23 having a triple-pipe structure together with the outer cylinder 21 and the inner cylinder 22 and having a rack formed in the outer periphery in the axial direction, and is rotatably supported by the intermediate cylinder 23 so as to be rotatable only. The inner cylinder 22 can be slid only by a key or a spline connection, and is integrally formed in the rotation direction with a shaft 24, a screw 25 attached to the lower end of the shaft 24 (see FIG. 1), and an illustration provided at hand. A pinion 26 that is rotated through a flexible shaft by operation of a handle not to be driven or is rotationally driven by a motor and meshes with a rack of the intermediate cylinder 23, and a gear disposed in a gear box 27 fixed to the upper end of the outer cylinder Clutch 28, an engine 29 whose output can be adjusted by manually operating a throttle valve, and a shaft (not shown) that is passed through a cylinder 31 attached to the gear box 27 and rotationally driven by the engine 29. ) And a shaft 33 that is integrally and rotationally slidably connected to the shaft in the rotational direction, is rotatably and slidably supported by the gear box 27, and moves up and down by operating the handle 22. Gears 34 and 35 are fixed, and a gear 36 that constitutes the clutch 28 together with the gears 34 and 35 is fixed to the shaft 33. The shaft 33 is lowered by operating the handle 32, and the gear 36 is moved as shown in FIG. When the gear is engaged with the gear 35, the shaft 24 and the screw 25 fixed to the lower end thereof are driven by the motor 29 as a driving source. When the shaft 33 is raised by operating the handle 32, the gear 36 transmits the rotation to the gear 34 via an intermediate gear (not shown), and the screw 25 is rotated in the opposite direction. It is designed to rotate. Then, by rotating the pinion 26 in the forward and reverse directions, that is, by raising and lowering the shaft 24 through the intermediate cylinder 23 and rotating the pinion 26 forward, feed is given to the screw 25 through the shaft 24, and the pinion 26 is rotated in the reverse direction. By doing so, the screw 25 is pulled up via the shaft 24.

  That is, the screw 25 is driven to rotate in the forward direction by using the motor 29 as a driving source while being fed by the drive of the pinion 26, thereby making a hole in the ground, and by rotating the pinion 26 in the reverse direction, the screw is rotated. 25 are to be raised.

  When soil improvement of an orchard or the like is performed using the soil conditioner of the present embodiment, the body frame 3 is pushed and moved in the orchard or the like and stopped at a predetermined position. Then, the set screw 14 is loosened, and the rod 15 is lowered to the ground to be fixed. This operation is performed before and after the body frame 3 to fix the body frame 3. When the orchard or the like tilts and the body frame 3 tilts in a stopped state, the rear wheel 2 can be raised and lowered by turning the handle 13 to level the body frame 3.

  Next, the screw 29 is rotated in the forward direction while the engine 29 is driven and the pinion 26 is rotated to provide feed, thereby making a hole in the ground such as an orchard. When drilling holes, the output of the engine is adjusted according to the ease of drilling, and when drilling is hindered due to the screw 25 getting caught in the root or the like, gears are switched by operating the handle 32, The drilling operation is performed while appropriately repeating the operation of rotating the screw 25 in the reverse direction.

  When a hole having a certain depth is formed, the operation of a handle (not shown) provided at hand is turned in the opposite direction, the pinion 26 is rotated in the reverse direction, and the screw 25 is pulled up to the ground. Thereafter, a gate (not shown) of the hopper 5 is opened, and the compost in the hopper is filled into the hole formed through the chute 17. After filling, the rod 15 is pulled out from the ground, and the set screw 14 is tightened and fixed. This operation is performed before and after the vehicle body frame 3 to release the fixing of the vehicle body frame 3, and then the above-described operation is repeated to make holes and fill the compost.

  In the above embodiment, only the rear wheel 2 of the front and rear wheels 1 and 2 can be moved up and down. In another embodiment, only the pair of front wheels 1 or both the front wheel 1 and the rear wheel 2 can be moved up and down. In still another embodiment, both the front and rear wheels are provided in pairs, and at least one of the front and rear wheels can be moved up and down.
