Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a device for picking up air-dried potatoes in a field.

Prior Art and Problems A center shovel is provided on the center line of the width side on the lower side of a towed traveling aircraft, and rotating discs are provided on both left and right sides of the shovel, and the discs are sunk underground and rotated, A potato picker is commercially available which is configured to carry potatoes and use the rotational force of a rotating disc to dig up the potatoes and transfer them onto a conveyor.

This well-known product is equipped with rotating discs on both the left and right sides of the center shovel, so foreign objects (roots, stems, leaves, soil clods, etc.) can get between the center shovel and each rotating disc while picking up potatoes. , gravel, etc.) may become trapped and impede the rotation of the rotating disk, and each time the foreign matter must be removed, reducing work efficiency. Additionally, if the foreign object is hard, such as gravel, the rotating disk may be distorted or damaged, making it impossible to pick up the potatoes or transfer them onto the digging conveyor. . Since the work is carried out while rotating the rotary disk, there is a risk of cutting the potatoes with the rotating disk or causing scratches such as scratches on the potatoes, so improvements are desired.

The present invention is proposed in response to such requests, and allows for efficient work without the risk of foreign objects getting caught.
To provide a useful potato picking device which can surely pick up potatoes and can work without damaging the potatoes.

Means for Solving the Problems The means of the present invention for achieving the above-mentioned object is to install a digging conveyor in front of the front end of the digging conveyor, the front end of which is installed low and obliquely on the lower side of the traveling machine. This means that a plurality of picking up rollers are arranged in parallel in the same direction as the lifting conveyor.

Function Rotates the excavation conveyor and multiple pick-up rollers of the traveling machine, causing the frontmost pick-up roller (end on the forward direction side) to be slightly buried in the ground,
Move the traveling aircraft forward. As the traveling machine moves forward, among the air-dried potatoes, the potatoes that are completely exposed on the ground surface are picked up by a pick-up roller near the digging conveyor and transferred to the digging conveyor. Potatoes that are partially exposed to the surface (e.g., half or just a little) are brought completely to the surface and picked up by a picking up roller at the frontmost part buried in the ground. The material is then transferred to a pick-up roller near the digging conveyor, and then transferred from the pick-up roller to the digging conveyor.

Embodiment A case of a tow type traveling body in which the traveling body is towed by a tractor will be explained with reference to the drawings.

The direction of the arrow shown in the figure is the forward direction of the traveling body 1, and the traveling body 1 is configured to move forward in the direction of the arrow shown in the figure, and to remove deposits attached to potatoes (for example,
Deposit removal equipment for removing foreign matter (e.g. stems, leaves, soil, etc.) that is mixed into potatoes (e.g.
The machine frame is equipped with a foreign matter sorting device to sort out gravel, clods, etc.), a potato sorting device to sort out damaged potatoes and other defective potatoes, etc.
Moreover, an escalator conveyor 4 for conveying potatoes to these devices is installed obliquely from the bottom of the machine frame toward the top of the machine frame, and an excavation conveyor 2 is provided close to the lower end of the escalator conveyor. . The digging conveyor 2 is the traveling machine 1
At the bottom of the escalator conveyor 4
An end (front end) on the forward direction side of the traveling body 1 is installed low and obliquely in front of the escalator conveyor near the lower end thereof, and the potato P picked up by the picking up roller 3 is transferred to the escalator conveyor 4. I will transfer it to. The digging conveyor 2 is a well-known roller conveyor installed in a potato harvester, and is provided with two conveyor shafts attached to the traveling body 1, respectively, and is moved clockwise ( (see Figure 1).
A plurality of picking up rollers 3 (two to three are considered, but two in the illustrated example) are arranged in front of the front end of the digging conveyor 2 (the end on the forward direction side of the traveling body). Rotates in the same rotation direction as the digging conveyor 2 by a chain 5 which is arranged in parallel and parallel to the conveyor axis of the digging conveyor 2 and suspended from the conveyor axis of the digging conveyor 2 to a roller shaft. do. Since the plurality of picking up rollers 3 must pick up the potatoes P without damaging them, rubber rollers made entirely of hard rubber rather than metal rollers, with a hard rubber layer formed on the surface of the hard roller body, are used. Although it is preferable to use a hardened composite roller, the roller is not limited to the above-mentioned rubber rollers, composite rollers, etc. as long as the roller has at least a surface layer of a material with some elasticity.

When carrying out work using a picking device with such a configuration, the traveling body 1 is connected to a tractor, and the picking roller 3 at the forefront is placed shallowly in the ground (for example,
10 cm), rotate the excavation conveyor 2 and all the pick-up rollers 3 using the power of the tractor, and move the traveling machine 1 forward by towing it with the tractor. Among the air-dried potatoes P, those that are completely exposed on the ground surface are picked up by the picking up conveyor 3 on the side closer to the digging conveyor 2 as the traveling machine 1 moves forward, and He was transferred to 2. Potatoes P that are incompletely exposed on the ground surface (for example, about half or just a little) or that are buried shallowly in the ground are completely exposed to the ground surface using the picking roller 3 at the front. It is picked up by the digging conveyor 2, transferred to the picking up roller 3 on the side closer to the digging conveyor 2, and transferred from the picking up roller to the digging conveyor 2. Potato P picked up like this
Because the picking up member is a roller,
They are picked up without worrying about getting hurt and are quietly transferred to excavation conveyor 2.

The traveling aircraft 1 may be a self-propelled aircraft equipped with an engine, and in this case, the digging conveyor 2, a plurality of picking rollers 3, etc. may be operated by the engine. .

Effects of the invention As the present invention is composed of multiple pick-up rollers as described above, there is less fear of foreign objects getting caught, and even if foreign objects are caught, they can be transported together with the picked up post. This eliminates the need to remove trapped foreign objects each time. Therefore, picking up potatoes can be carried out efficiently. and,
There is less worry that the plurality of rollers will be distorted or damaged by foreign objects, and the potatoes can be picked up reliably. Furthermore, the risk of cutting or damaging the potatoes is reduced, and the occurrence of defective potatoes due to picking up work is reduced.

Therefore, the intended purpose can be achieved.
