DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine for digging and harvesting long root vegetables such as burdock.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 5-268816 is known as a root vegetable harvesting machine in which a series of steps from extraction of radish to cutting of leaves are mechanized. In this known technique, an auxiliary mechanism called a side-twisted conveying device to change the root vegetable main body conveyed by the lifting conveying mechanism to the reclined posture,
Alignment is performed using a conveyor mechanism that transports the patient in a lying position.

[0003]

SUMMARY OF THE INVENTION The above-mentioned Japanese Patent Application Laid-Open No. 5-2 is 5-2.
No. 68816 is suitable for relatively short root vegetables such as radishes. At present, root leaves with a long diameter of 70 cm to 1 m, such as burdock, are obtained by cutting the leaves in advance and page (2). Therefore, the present invention is to lighten and align them with a simple configuration.

[0004]

In order to solve the above-mentioned problems, an uneven body is provided at the lower end of the beam, and a rear edge of the uneven body that is inclined upward is positioned near the starting ends of the pair of conveyor belts. In the root crop harvesting machine, wherein the root is picked up by the conveyor belt and pulled out, the inner wall and the outer wall, which are flexible with respect to the longitudinal direction of the frame installed at the lower rear end of the conveyor belt, are parallel. A pressing member is horizontally disposed substantially at the center of the inner wall, and the pressing member is provided rotatably with respect to the support boss, and a weight is attached to the opposite side of the support boss. The present invention provides a root crop harvester characterized in that a shooter is provided to guide and align long-diameter root crops. Further, the shooter is inclined rearward in a plan view, the inner surface is inclined in a rear view, and the upper part gradually comes into contact with the lower end of the root vegetable, and the root of the root vegetable is aligned and released so that the neck part falls backward. The above-mentioned root vegetable harvesting machine. In addition, the root vegetable harvesting machine described above is connected to a transport cart so as to straddle the left and right of the shooter below the lower part of the parallel shooter.

[0005]

When the harvester according to the present invention is brought into the field and harvesting is started, the rising body at the lower end of the beam pulls out the root vegetables, and the starting ends of the pair of conveyor belts follow the root of the root vegetables. Grasping and transporting it backwards to ascend and completely remove the root vegetables. At the rear of the conveyor belt, when it is released, it is aligned and dropped while being aligned in the front-rear direction by a parallel shooter made of a flexible material. At this time, since the flexible material is used, the large and small root vegetables are aligned without damage while appropriately colliding, so that the post-processing is easy. Further, the shooter is inclined rearward in a plan view, the inner surface is inclined in a rear view, and the upper part gradually comes into contact with the lower end of the root vegetable, and the root of the root vegetable is aligned and released so that the neck part falls backward. The neck is aligned neatly in one direction toward the rear of the root crop harvester. In addition, since the transport vehicle is connected so as to straddle the left and right of the shooter below the lower part of the parallel shooter, the root crop harvester neck is aligned in one direction toward the rear and mounted and stored on the transport vehicle. You. Therefore, it can be carried out of the field as it is on page (3).

Reference numeral 28 denotes a support frame which is connected to the frame of the transfer device 25 and protrudes rearward. A shooter 29 composed of an inner wall 30 page (5) and an outer wall 31 is disposed on the support frame 28 so as to be inclined with respect to the center direction of the pair of conveyance bodies. It is installed so as to be located almost at the center. The loading platform 19 is arranged below the lower part of the parallel shooter 29 so as to straddle the left and right sides of the shooter. The base of the tow rod 11 is supported by the support pin 26 and the angle can be changed by the auxiliary rod 20. The length of the auxiliary rod 20 is adjusted according to the cultivation furrow or the tractor wheel.

FIG. 4 is a plan view of the supporting body of the flat body, and the spatula 12 forming the flat body has a blade plate at the tip and a resin material stretched over the upper surface of the main body, and is tapered toward the rear. The extension rod 34 is fixed. Reference numeral 23 denotes a guide member, which guides the holding start end of the carrier 7 so as to hold the vicinity of the neck portion of the root vegetables, which is provided on the side of the crank 14 in the present embodiment and is directed outward. It is elastically attached by the coil spring 37.

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 provided rotatably with the base shaft 33 as a fulcrum with respect to the support boss 40, and an appropriate weight 35 is attached to the opposite side of the pressing member 32, and the pressing force is varied depending on 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 portions of the inner wall 30 pressed by the pressing member 32 preferably contact 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.

[0017]

As described above, the root vegetables of long shoots such as burdock will rise to the surface of the soil, and the neck of the root vegetables will be securely clamped by the carrier, and will be continuously extracted. Since it is left horizontally aligned in one direction toward the direction, the harvesting operation at the rear is more efficient. When the released root vegetables are directly received by a cart, the roots are aligned rearward and stored, and released from the field in the same process.
