Description

[Detailed Description of the Invention] This invention relates to a device for preventing damage to potato shingles discharged from a tank of a harvester.

The harvester stores the excavated potato in the tank, and when it is full, discharges the potato from the tank to a designated place, but if the discharge head is close to 1 meter, The damage incidence is quite high.
Various devices have been proposed to prevent this damage to the potato harvester, but none of them can be attached to the harvester all the time, so they have to be attached and detached each time they are discharged. Besides,
The damage prevention effect was also not always satisfactory.

The purpose of this invention is to provide a device that can be permanently installed in a harvester and that reliably prevents damage to the potato tails being discharged.

The device of this invention will be explained based on the embodiment shown in the drawings. As shown in FIG. 1, a metal fitting 1 is fixed to the discharge end of a tank 5 of a potato harvester, and a receiving frame 2 of the upper stage of the damage prevention device is attached to the metal fitting. The middle and lower receiving frames 2' and 2'' are also the same shape and size as the upper receiving frame 2.The middle and lower receiving frames 2' are connected via wires 4 passed through rings 3 formed at the four corners of each receiving frame. ，
2" are suspended and connected from the upper receiving frame 2, and the vertical spacing of each receiving frame is kept constant. Milling wheels 13 are provided at the center of both sides of each receiving frame 2, 2', and 2", and the lifting wire 6 is passed through the center of each receiving frame. The lower end is locked to the ring 5 of the lower receiving frame 2'' via the stopper 7.

As shown in FIG. 2, the receiving frame 2 consists of a rectangular metal peripheral frame 8, double chevron-shaped side plates 9, 9', and a chevron-shaped central receiving plate 10 that connects the central portions of these plates. It consists of front and rear receiving plates 11 and 12 that connect the oblique sides that are inclined to the front side. Rings 3 and 13 are fixed to the four corners and the center of both sides of the metal peripheral frame 8. The center receiving plate 10 and the front and rear receiving plates 11 and 12 are made of a soft material such as rubber, synthetic resin, or fiber, or the front surface is made of such a soft material and the back surface is reinforced with a metal plate or the like. The lower halves of the front receiving plate 11 and the rear receiving plate 12 are projected below the central receiving plate 10, and the gap between the lowermost ends thereof is formed to be equal to or slightly wider than the width of the central receiving plate 10.

Next, a description will be given of how the device of this invention prevents damage to potato shiyo. As shown in FIG. 1, the potato tails 15 in the tank 5 are carried on the conveyor 16 and dropped into the upper receiving plate 2 from the discharge end. A horsetail that has fallen into the receiving frame 2 first hits the central receiving plate 10 and falls in either the front or rear direction along the mountain shape as shown by the arrow. Then, it hits the front receiving plate 11 or the rear receiving plate 12 and moves along it to the middle receiving frame 2'.
fall towards the center of the As shown by the arrow, the inside of the middle receiving frame 2' is similar to the inside of the upper receiving frame 2.
From the center receiving plate 10 to the front receiving plate 11 or the rear receiving plate 12
It then falls to the center of the lower receiving frame 2''.It also falls inside the receiving frame 2'' as shown by the arrow and falls to the ground. Until the potato falls to the ground, it hits six receiving plates: the upper, middle, and lower central receiving plates 10 and the front receiving plate 11 or the rear receiving plate 12. Every time the horsetail hits the receiving plate, the falling energy is absorbed by the receiving plate made of soft material. Therefore, the impact when it falls to the ground is extremely small, and the horsetail will not be damaged. The horsetail hits the receiving plate six times, but the impact is only a small drop, and the receiving plate is made of soft material, so the horsebell is not damaged at all. Although the device of the embodiment is equipped with a three-stage receiving frame,
When the discharge height is low, two stages are sufficient; on the other hand, when the discharge head is large, it is desirable to provide a receiving frame with four or more stages.

When the potatoes are not to be discharged, the wire 6 is pulled up and its tip is hooked to the latch 17 of the tank 5 as shown in FIG.
The three stages of receiving frames 2, 2', 2" made of soft material of the same shape and size overlap each other to form a compact structure, so that even if they are left installed, they will not become cluttered or interfere with other work.

As mentioned above, the device of this invention has a simple structure, but it not only accurately absorbs the falling energy of the ejected potato shiyo and prevents damage to it, but also allows it to be stored compactly when not in use, allowing for harvesting. It can be permanently installed on the machine.

Claims (1)

[Claims for Utility Model Registration] (1) A plurality of receiving frames that can be stacked vertically are suspended from the discharge end of a tank of a harvester at a predetermined interval, and the receiving frames are made of a soft material and extend from side to side. A central receiving plate having a chevron-shaped cross section is provided, and front and rear receiving plates made of a soft material and inclined inward are provided on the receiving frame, and the lower portions of the front and rear receiving plates are extended below the central receiving plate, and both A damage prevention device for potato shingles, characterized in that a lower gap is made equal to or larger than the width of the center receiving plate. (2) In the device described in paragraph 1 of the claims for utility model registration, the uppermost receiving frame is attached to a metal fitting fixed to the tank, and the receiving frame is hung from rings provided at the four corners of the peripheral frame of the rectangular receiving frame. The apparatus is characterized in that the receiving frame is hung down through a lowering wire, and a lifting wire is passed through a ring provided at the center of both sides of the peripheral frame, so that the receiving frame can be stacked by pulling up the lifting wire when not in use.
