Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a device for preventing spillage of harvested products in a rotary bucket-type ascending conveyor of a root vegetable harvester.

[Conventional technology]

It is a rotary bucket container with a U-shaped cross section, with the outer periphery serving as the bottom and the inner periphery serving as the inlet and outlet for the root vegetables to be transported. There is a rotary bucket-type ascending conveyor in which the terminal end and starting end of two upper and lower conveyors are inserted into a central cavity.

[The problem that the idea aims to solve]

In the above-mentioned conventional ascending conveyor, the object to be transferred is thrown from the end of the lower conveyor to the lowest level of the rotary conveyor, and is rotated upward by the action of the rotary conveyor, and when it reaches a predetermined height, it is thrown. The mouth opens at the bottom so that the vegetables fall to the starting point of the upper conveyor installed at the bottom of the opening. degree,
Also, due to complex reasons such as the rotational speed of the rotary conveyor itself, some items may not be placed on the upper conveyor, but instead jump over it and fall, flying back into the input slot that opens at the bottom of the rotary conveyor. Some fly out from the opening and fall to the ground.

In this case, items that have fallen into the rotary conveyor again are conveyed by the above-mentioned action, but items that have fallen to the ground must be picked up as post-work.

This idea was developed in order to avoid the above-mentioned inconvenience, and when the conveyed object is discharged to be placed on the upper conveyor and falls over the upper conveyor, it will not fall to the ground. The purpose is to make it possible to lead the rotary conveyor back to the input port opening at the lower part of the rotary conveyor.

[Means to solve the problem]

As a means to achieve the above-mentioned purpose, this invention has a steel wire made into a groove shape with a substantially U-shaped cross section,
An annular cage is formed with the bottom as the outer diameter and the opening edge as the inner diameter, and the inside of this U-shaped groove is partitioned in the centrifugal direction with a plurality of partition pieces at appropriate intervals, and this is connected to the rear of the harvester. In the case of a rotary bucket installed so that it can freely rotate in the vertical direction by receiving power, the partition piece that is at the uppermost position rotates downward at the inner peripheral position of the rear surface of the rotary bucket. The rotating position is the starting point, and the plate is fixed to the rotary bucket that rotates as part of the machine frame in a range that ends at the point where the perpendicular line below that position intersects with the diameter horizontal line at least on the downward rotation side. It is something that can be maintained and installed.

[Effect]

Root vegetables are dug up while being towed by a towing vehicle such as a tractor, transported backwards by a rotary conveyor, and placed into the input port of a rotary bucket that opens below the end of the rotary conveyor. The type of transport object lands in the pocket-shaped recess formed by the partition piece provided in the centrifugal direction with respect to the annular shape of the rotary bucket cart and both walls, and is transferred to the upper part by the driving rotation of the rotary bucket cart. The above-mentioned input port faces downward so that objects to be transported can be discharged onto the starting end of the upper rotary conveyor, which is located at a position where they can fall naturally. Among the objects that have jumped over the upper rotary conveyor due to the amount of sliding resistance due to lumps, etc., or when the rotation speed of the rotary bucket cart is uneven, the objects that have jumped backward from the central opening on the rear surface of the rotary bucket cart. The root vegetables come into contact with a plate installed at that location, are adjusted to fall directly downward, are guided so that they can fall into the input slot that opens at the bottom, and are rotated again after falling into the rotary bucket and then upward. It is something that is transported. It also prevents it from falling to the ground.

〔Example〕

Next, an embodiment of this invention will be described with reference to the drawings. A steel wire is formed into a groove having a substantially U-shaped cross section, and an annular casing is formed with the bottom being the outer diameter and the opening edge being the inner diameter. A rotary bucket which divides the entire groove in the centrifugal direction with a plurality of partition pieces 3 at appropriate equal intervals, and which is attached to the rear of the harvester 1 so that it can freely rotate in the vertical direction by receiving power. 2, the starting point is the inner peripheral position of the rear surface of the rotary bucket 2, where the uppermost partition piece 3 turns downward rotation, and a perpendicular line below this position and at least the descending The plate 5 is attached to a part of the machine frame 6 so as to remain immovable relative to the rotating rotary bucket cart 2 in a range ending at a position intersecting the diametrical horizontal line on the rotating side.

The plate 5 is inclined forward as it goes to the bottom, and the upper end protrudes a little rearward than the inner link 4 of the rotary bucket belt 2, or may be flush with the inner link 4, and the lower end projects slightly into the inner link 4. The plate 5 positioned at is attached to the machine frame 6 as appropriate.

The machine frame 6 may be formed so as not to interfere with the rotation of the rotary bucket cart 2 and the driving work of the upper and lower rotary conveyors 7, 8, and may be attached to a vehicle body or the like.

9 indicates a bucket.

[Effect of idea]

By providing a plate on the descending side of the rotary bucket cart, root vegetables that have jumped over the upper rotary conveyor can be brought back into the rotary bucket by hitting the plate. Since the root vegetables do not fall onto the ground, the harvesting work can be carried out efficiently by omitting the work of picking up the root vegetables.
