Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a method for harvesting potatoes.

(Conventional technology) Traditionally, potato mackerel is harvested by, for example, digging potatoes,
The material is transported to a conveyor made up of a large number of horizontal rods arranged side by side.
A method of shaking off soil from between the side bars of this conveyor and storing it in a container while conveying potatoes with this conveyor, and a method of shaking off soil with the conveyor as described above and further Usually, the stem vegetables are separated and removed from the potatoes between rollers while being conveyed to a roller conveyor, and then stored in a container.

(Problems to be Solved by the Invention) According to the conventional harvesting method as described above, potatoes are conveyed while being transferred on each horizontal rod or roller of the conveyor during the transportation process by a conveyor, and as a result, they become hard and hard. There is a problem in that the outer skin of potatoes may peel off due to contact with the beating or rollers, or may be damaged by bruises, resulting in quality deterioration during transportation.

In particular, recently, potato butterflies have come to be used for raw consumption and as a raw material for food processing, so product 11 (
If? Security has become a serious issue.

Therefore, the present invention was developed in view of the above circumstances, and therefore, it is difficult to treat potatoes with peeling of the skin surface or bruises.
(The purpose of this work is to provide a method for harvesting potatoes that ensures quality and allows harvesting without causing damage.)

(Structure of the Invention) (Means for Solving the Problems) The potato harvesting method of the present invention involves digging up a potato carrier, transporting the soil along with the belt conveyor, and picking up the potatoes during the transport. It is then stored in a container.

(Function) According to the potato harvesting method of the present invention, the potatoes are dug up, and the soil expanded and softened by digging the potatoes is conveyed to a belt conveyor, and the potatoes are conveyed together with the soil.

During this conveyance, the potatoes are picked up and stored in a container, while the soil is directly conveyed to the field from the conveyance end of the conveyor.

(Example) Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

In the figure, 1 is a main frame as a machine frame, and side frames 2 as machine frames are fixed to both ends of this main frame 1 in a parallel manner facing each other.
A chassis 3 is fixed to the rear lower part of the opposing side frames 2, and wheels 4 are rotatably mounted on both sides of the chassis 3.

A transmission 6 having an input shaft 5 is fixed to the middle part of the main frame 1, and a lower arm 8 having a wabbin 7 at its tip protrudes forward on both sides of the main frame 1. . Further, a top arm 10 having a connecting portion 9 at its tip protrudes forward from the upper part of the IYN side of the opposing side frame 2, and the front side of this top arm 10 gradually approaches the front end thereof and the lower arms on both sides. 8 near the front end thereof is connected by a stay 11.

Further, a tip 12 as a moat raising body is protruded between the lower front ends of the opposing side frames 2, and a first belt conveyor 13 as a belt conveyor is installed at the rear end of the tip 12, tilting upward. They are installed consecutively. This first bell mill conveyor 1
Reference numeral 3 denotes a driven roller 14 rotatably mounted on a shaft on the side frame 2 in close proximity to the rear end of the tip 12, and a drive roller 14 rotatably mounted on a shaft on the upper rear end of the side frame 2. It is composed of a roller 15, a guide roller 16 rotatably mounted in front of the drive roller 15, and an endless belt 17 made of a flat belt rotatably suspended between these rollers 14, 15, and 16. , and this endless belt 17 has a large number of locking protrusions 18 projecting in the width direction thereof at predetermined intervals. One end of the drive shaft 19 to which the drive roller 15 is fixed and the output shaft 20 of the mission 6 rotate via an interlocking medium 21! l) They are freely interlocked and connected.

Further, an extension side frame 2 is attached to the upper part of the middle platform 3 via a support frame 22.
3 are arranged opposite to each other, and the front end of the extended side frame 23 is fixed to the upper rear end of the side frame 2.

Also, conveyor frames 24 are provided in parallel to each other at a predetermined interval on the inner sides of the opposing extension side frames 23, and a second belt conveyor 25 as a belt conveyor is installed approximately horizontally between the conveyor frames 24. It is set up in a shape. The second belt conveyor 25 includes a driven roller 26 installed directly below the drive roller 15 of the first belt conveyor 13 and rotatably mounted on the conveyor frame 24, and a driven roller 26 that is rotatably mounted on the conveyor frame 24. It is composed of a drive roller 27 which is rotatably mounted on the rear end thereof, and an endless belt 28 which is a flat belt suspended between these rollers 2G and 27 so as to be rotatable. Further, one end portion of the driven shaft 29 to which the driven roller 26 is fixed is rotatably coupled to the drive shaft 196 of the first belt conveyor 13 via an interlocking medium 30.

Moreover, there are 1J10 vertically spaced input ports 31 between the opposing extension side frame 23 and the conveyor frame 24 inside the extension side frame 23, and a large number of input ports 31 are provided at the outer opening edges of the lower ends of the input ports 31 on both sides. A chute 33 with inclined rods 32 arranged side by side is mounted so as to be inclined inwardly, and an opening of a container 34 placed on the chassis 3 is opened between the lower ends of the chutes 33 on both sides. ing.

Furthermore, platforms 35 are fixed horizontally to the lower portions of both sides of the vehicle chassis 3. Note that 36 is a guide.

Next, in the above configuration, the lower pins 7 on both sides and one connecting portion 9 are connected to the three-point suspension mechanism of the tractor, and the input shaft 5 is connected to the power take-off shaft portion of the tractor via the power transmission shaft.

Then, the harvester is pulled by the tractor (1), and the endless belts 17 of each of the first and second belt conveyors 13.25 are driven by the power input from the tractor.
．． 28 in the clockwise direction in Figure 1, the tip is 12"C.
- While the potatoes in the field are dug up, the potatoes and the soil expanded and softened by the digging of the potatoes are both carried into the endless belt 17 of the first belt conveyor 13 and conveyed upward. Then, the potatoes, soil, etc. are transported from the unloading end to the endless belt 28 of the second belt conveyor 25.
It is carried upward and further transported to the rear.

At this time, that is, when the potatoes are conveyed by the second belt conveyor 25, the Blattbohm 35
The worker riding on the machine sequentially picks up the potatoes to be harvested, and puts the potatoes into the input port 31.
While being stored and harvested in a container 34 through a chute 33, the soil, grass leaves, etc. on the endless belt 28 that are not picked up are discharged as they are from the discharge end to the Idil field.

〔Effect of the invention〕

According to the present invention, the quality of the potatoes is ensured by transporting the soil along with the soil onto a belt conveyor, which prevents the skin surface of the potatoes from peeling off or being damaged by bruises due to the buffering effect of the soil. It can be harvested as it is.
