[0004]
[Problems to be solved by the invention]
The above-mentioned conventional root vegetable harvesting means is to pick up the root vegetables that are picked up from the cultivation basket and laid down in the field and pick up by the worker who walks following the root vegetables harvester. When loading onto the loading platform, the traveling vehicle must move sideways toward the traveling vehicle each time it grabs the root vegetables that have been released by running the cultivated vines that have already been harvested. Thus, there is a problem that the efficiency of the work of collecting root vegetables is poor.
[0005]
Further, as another means, the pulling conveyor is stretched and stretched in an L-shaped state in which the opposing holding belt is bent at a right angle toward the already harvested land in plan view. There is a means for releasing the root vegetables to the farm scene in a posture orthogonal to the traveling direction of the aircraft.
[0006]
Among the conventional means, a means for providing a stocker with a lateral feed conveyor below the end side of the pulling conveyor is used to feed the root vegetables released on the cultivated culm that has been harvested by the lateral feed conveyor. It is a means to improve the workability of this harvesting work by laterally feeding it to the site of the cultivated culm that has finished harvesting, but the conveyor mechanism for lateral feeding increases the weight As a result, the rear end of the harvester's body is made heavy, which makes it difficult to operate the aircraft, and when a small tractor is used, a large amount of balance weight must be mounted. However, combined with the complexity of the structure by incorporating the lateral feed conveyor mechanism, another problem has arisen that significantly increases the production cost and makes the harvesting machine expensive.
[0007]
Further, in the third means for stretching the pulling conveyor in a shape bent in an L shape in plan view, root vegetables discharged from the end portion of the pulling conveyor are conveyed while being pulled up by the pulling conveyor. By being transferred to the already harvested land side and being left in the field, the bottom side of the pulling conveyor collides with the front side of the transporting direction of the root vegetables being transported, and the sideways posture is regulated. By providing a restricting member, the root side to be gripped when picking up root vegetables is positioned on the already harvested land side so that it is in a posture perpendicular to the traveling direction of the aircraft and left in the field. Therefore, each time the root vegetables are picked up from the field scene, the operator does not need to reciprocate between the harvested cultivation basket and the accompanying vehicle traveling on the already harvested land side, and the pulling conveyor is The transport route of the plan view It is configured to be bent in an L shape at the same time, so that the weight burden is much smaller than when a transverse feed conveyor is installed, so that the advantage of facilitating the operation and operation of the aircraft can be obtained. Become.
[0008]
However, the root vegetables that are left in a lying position in the farm scene are in a posture that is orthogonal to the advancing direction of the aircraft in plan view. A work process in which the walking worker changes the direction to the direction of the accompanying car at the collection position, changes the direction to face the direction of the root vegetables, picks up the root vegetables and converges. Therefore, in practice, there is a problem that workability cannot be improved.
[0009]
The present invention was made to solve the above-mentioned problems occurring in the conventional means, and the following operator picks up the extracted root vegetables without using a heavy feed conveyor. It is an object of the present invention to provide a new means for releasing an accompaniment vehicle into a field scene as a state where the work to be loaded can be performed with good workability.
[0010]
[Means for Solving the Problems]
And in the present invention, as means for achieving the above-mentioned object, the root vegetable digging upper body mounted on the airframe that moves by self-propelled or the airframe that moves by the towed object is the root of the cultivation row of root vegetables. The root vegetables are lifted together with the soil through the ground, and the root vegetables are picked up and pulled out by a pulling conveyor consisting of a clamping belt that rotates endlessly facing the root vegetables. In the method of harvesting root vegetables to be discharged to the root, the root vegetables picked up by the pulling conveyor are in a posture in which the tail side is forward in the forward direction of the aircraft and the head side is backward in the plan view. Than the tail side The amount of deviation of the root crops Proposed a method of harvesting root vegetables characterized by being deviated to the already harvested land side and laying in an oblique posture inclined with respect to the aircraft traveling direction and released to the field scene, The root vegetable digging body that floats along with the soil through the root of the root vegetable cultivation line, and the root vegetable digging body that floats on the body moving by self-propelled or moving by towed machine In the root vegetable harvesting machine in which a pulling conveyor consisting of opposing clamping belts that pinch and pick up the roots of the set root vegetables is mounted on the machine body, the pulling conveyor is located at the start side in the transport direction thereof. Positioned above the rear end of the upper body or above the rear end of the upper body, at least the second half side in the transport direction is gradually displaced toward the harvested land side toward the terminal end, The end part is shifted to the already harvested land side by the amount of deviation of about 1% of the cultivated rice of root vegetables, An oblique posture that is inclined with respect to the traveling direction of the aircraft in plan view do it The body vegetable is mounted on the lower surface of the pull-out conveyor, and the root vegetable is transported while being pulled up by the pull-out conveyor. Equipped with a regulating member that regulates to change the posture And The extracted root vegetables are placed on the already harvested land side with the head located behind the aircraft in the direction of travel.
