DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine for extracting and harvesting root vegetables by ultra-deep cultivation of burdock or the like.

[0002]

2. Description of the Related Art As a conventional root crop harvesting machine, it is known that the harvesting of root vegetables is carried out.
No. 22423 is known. In particular, for soft crops to be mined, such as yam and radish, the main body of the soft crop is inclined downward from the rear part toward the front part so as to be arranged in an inverted figure on both sides. At the same time, the cutting edge is inclined downward in the direction opposite to each other and disposed on the main body, and an appropriate number of earth receiving rods of an appropriate length are protruded rearward horizontally on the upper rear surface of the main body. Formed Page (2) This is a soft crop digger characterized by being squeezed. Japanese Patent Application Laid-Open No. 2-49507 is also known, and this known technique is designed so that rooted vegetables can be lifted and suspended and conveyed before sinking. It was done.

[0003]

SUMMARY OF THE INVENTION
No. 2423 raises soft crops such as yam and radish to the surface of the soil by the earth pressure of the excavated soil while preventing damage during excavation, after which the work of extracting and collecting the lower half remains. . Japanese Patent Application Laid-Open No. 2-49507 has a conveyor for holding and transporting the raised root crops in the loading section. Although the soil around the burdock is separated, the height at which the burdock floats is small, making it difficult to continuously grip the burdock neck. In addition, even if the wide excavation body is extended and inclined, the excavation resistance may become too large and traveling may become difficult. Therefore, there are also problems that do not fit into the center of the conveyor, and that the earth mass is not loosened and stays.

[0004]

In order to solve the above-mentioned problems, a pair of beams and a pair of parallel bodies are provided at the lower ends of the beams so as to oppose each other in an inverted octagonal shape when viewed from the front. In a harvester for extracting root vegetables, which is configured to be located near the starting end of a pair of conveyor belts whose rear edges that are inclined upward to the bottom of the body are inclined, the pair of parallel bodies are swingable in the vertical direction. The rear end of each is formed into a rod-shaped rail, and the root vegetables and the surrounding soil that have surfaced on the surface by the pair of bodies are sieved and sorted by the vibration of the rod-shaped rails. The present invention is to provide a root crop harvesting machine characterized in that only the root vegetables are guided by a conveyor belt to be pinched and pulled out. Further, the root crop harvesting machine is characterized in that a bar-shaped rail is formed so as to be extendable and contractible in the traveling direction so that the distance from the starting end of the conveyor belt can be adjusted. Page (3) Also, a horizontal guide member is provided on the upper part of the beam provided with a pair of limbs, and the neck portion of the root vegetable that has surfaced on the surface layer by the pair of limbs falls to the side. The root crop harvesting machine described above, wherein the root crop harvesting machine is prevented.

[0005]

[Function] A pair of arms are provided at the lower end of the beam so as to oppose each other in an inverted octagonal shape when viewed in the front-rear direction. Act to lift upwards,
The root crops float up to lift the soil. At this time, the rear edge of the pair of parallel bodies inclined upwards is located near the starting end of the pair of conveyor belts. Move to the surface of. At this time, since the body is oscillating in the vertical direction, the bottom root of the root vegetable is appropriately vibrated by applying vibration to the lower end thereof, and the floating root vegetable and the surrounding soil are moved by the rail that vibrates vertically. The roots are loosened and sorted, and the root of the root vegetable collides with the start end of the conveyor belt and is pinched. The conveyor belt holding the root vegetables is rotated backward at a high speed to remove the whole root vegetables. Further, when the soil around the root vegetables is hard and cannot be loosened, extending the rail longer increases the amount of vibration and increases the sieving and sorting ability. If the root planting position is off the center, or if the root of the root plant is going to fall to the side, the pair of guides provided horizontally will prevent the root plant from falling and prevent the root from falling. To force the roots to be pinched.

An extension rod 34 is fixed to the rear end. 23 is a guide material,
In this embodiment, the roots are guided to the clamping start end of the transporting body 7 so as to hold the roots around the neck portion of the root vegetables. In the present embodiment, a coil spring 37 is provided outwardly.
Has been hit by

FIG. 5 is a perspective view of the shooter in which a flexible inner wall 30 and an outer wall 31 hang down parallel to the longitudinal direction of a rectangular frame 39. A pressing member 32 is horizontally disposed substantially outside the central portion of the inner wall 30. The pressing member 32 is rotatably provided with the base shaft 33 as a fulcrum with respect to the support boss 40, and a weight 35 is appropriately attached to the opposite side of the pressing member 32 to vary the pressing force according to the growing condition of the crop. The inner wall 30 and the outer wall 31 are suitably made of a rubber material or a synthetic resin material, and the protruding portion of the inner wall 30 pressed by the pressing member 32 preferably contacts the outer wall. Therefore, the root vegetables 38 sandwiched and transported by the pair of transport bodies first contact the lower end of the root vegetables with the inner wall, and the neck portion falls backward,
Gradually, the roots of the root vegetables come into contact with each other, fall down and are discharged in the horizontal direction, and are nipped between the inner and outer walls 30, 31 and left linearly and continuously in the traveling direction.

FIG. 6 shows a state in which the rail 34 is attached. A backing plate 43 forming the base of the rail 34 is fixed to the back surface of the spatula 12 by bolts 45 with the long hole 44 set at an appropriate position. is there. The length of the rail is varied as desired.

[0018]

As described above, the root vegetables having a long diameter such as burdock float up to the surface of the soil, the root vegetables are sieved and separated from the surrounding soil, and their necks are securely clamped by the carrier.
After being continuously extracted, it is left horizontally aligned in one direction toward the traveling direction, so that the harvesting operation at the rear is easy. In addition, since the released root vegetables are stored directly in a cart with their necks directed rearward, the root vegetables are discharged from the field in the same process, and the harvesting work is significantly labor-saving.
