[Industrial applications]

 The present invention relates to a processor for extracting and processing stems and leaves of potatoes and the like.

[0002]

[Prior Art]

 In recent years, in potato cultivation, there have been many methods of artificially spraying the defoliation agent and killing the above-ground part for the purpose of preventing epidemics of viral diseases and facilitating the work of harvesting potatoes. As a device for treating foliage, there is known a device for cutting the vines of potatoes on the ridge (Japanese Utility Model Publication No. 2-3707).

[0003]

[Problems to be solved by the device]

 Spraying of defoliants is likely to cause physiological disorders such as browning of vascular bundles such as potatoes, and has problems such as deterioration of storage stability. Therefore, it is highly likely that the use of defoliants will be abolished.

Further, Japanese Utility Model Publication No. 2-3707 has a problem that after cutting the vine, the remaining stems including the underground part remain.

If the stem remains attached to the potato or the like, there is a problem that the quality of the potato becomes poor due to re-sprouting from the stem or invasion of pathogenic bacteria from the cut end.

An object of the present invention is to obtain a foliage processing machine capable of extracting foliage such as potatoes and vines from a potato.

[0007]

[Means for Solving the Problems]

 In this invention, a foliage processing machine such as potato is composed of a stock separating means, a foliage removing means, an underground part pressing means, and a foliage crushing means.

A foliage processing machine such as potato is composed of a stock separating means, a height-adjustable foliage removing conveyor, an underground part pressing roller, and a foliage crushing device.

Alternatively, a potato-leaf foliage processing machine comprises a stock separation means, a height-adjustable foliage removal conveyer, an underground part pressing roller, and a foliage crushing device, and the position of the underground part pressing roller is The configuration is such that it is located slightly behind the foliage extraction position of the foliage extraction conveyor.

[0010]

[Action]

 Strain separating means extends into the ridges and separates the entangled foliage for each strain. Next, while pulling out the stems of potatoes etc. for each strain by means of a stem removing device such as a stem removing conveyor, at the same time, the underground part pressing roller of the strain presses the ridge surface, so the stems of potatoes It is pulled out from the base and pulled up. The potato remains in the soil as it is. The foliage that has been pulled up is crushed by a foliage crushing device and spread as it is on the field.

Further, since the height of the foliage removing position of the foliage extracting conveyor can be adjusted, the height of the ridge and the state of the potato can be dealt with.

The two inner and outer endless conveyors 3 have a shape in which the front is opened in the shape of a flat funnel, and the foliage 20 is sandwiched at the position where the inner and outer endless conveyors 3a and 3b, which are the funnel-shaped bases, come into contact.

The foliage extracting conveyor 3 is configured such that the foliage extracting position is located at about several tens cm above the ridge surface 22 and rises toward the rear. The height of foliage removal is adjusted by the gauge wheel 5, which is the front wheel. The gauge wheel 5 is rotatably attached to the front part of the mounting frame 1, and the height of the mounting frame 1 is changed depending on the position thereof to adjust the height of the foliage extracting position. The convex elastic band 4 provided over the entire surface of each endless conveyor is made of sponge, rubber, soft synthetic resin, or the like. 6 is a rear wheel.

Reference numeral 7 denotes a pressing roller which is an underground part pressing means, and there are two pressing rollers corresponding to the left and right foliage removing conveyors 3a and 3b. Each pressing roller 7 has a drum-like outer shape, and the cylindrical surface is concave so as to correspond to the convex shape of the ridge surface 22. The pressing roller 7 is a roller which is located slightly rearward of each foliage removing position, has an appropriate weight, and is urged downward by an urging means such as a spring 19 so as to be freely rotatable.

Reference numeral 8 is an auxiliary plate. The auxiliary plate 8 faces the larger outer endless conveyor 3a at a position where the outer endless conveyors 3a, 3b outside the inner and outer endless conveyors 3a do not face each other with a narrow space therebetween, and by the elastic body 9 such as a spring, It is biased to the surface of the outer endless conveyor 3a. The elastic band 4 may be provided on the surface of the auxiliary plate 8.

The outer endless conveyors 3a of the two foliage extracting conveyors 3 are formed in a plane C shape, and the left and right foliage extracting conveyors 3 face each other at a narrow interval at the highest position of the rear end.

Reference numeral 10 is a foliage crushing device. A plurality of flare blades 10b are rotatably provided by a rotary shaft 10c in a bucket 10a having an inlet opening below the rear end of the foliage extracting conveyor 3.

The power transmission mechanism includes a pipe frame 11 attached to a frame, a main mission 12 attached to the pipe frame 11, an input shaft 13 of the main mission 12, and a rotation of the main mission 12 to a horizontal shaft 15. To the rotation shaft 10c of the foliage crushing device 10, a transmission case 14 for transmitting the rotation of the main mission 12 to the rotary shaft 10c, and a drive shaft for driving the outer endless conveyor 3a through a transmission box 17 through which the horizontal shaft 15 penetrates. 18a, a drive shaft 18b for driving the inner endless conveyor 3b, and the like.

Next, the operation of this invention will be described. The foliage processor is pulled by the tractor. In the foliage processing machine, the three dividers 2 located in front of it are located in the ridges 23, and the two pressing rollers 7 are located on the adjacent ridges 22. When the foliage processor is pulled by the tractor, the foliage 20 stretched and entwined between the ridges is cut and separated, and each ridge and each strain are separated.

Power is transmitted from the PTO of the tractor to the main mission 12 via the input shaft 13. Further, the power is driven from the main transmission 12 by the pipe frame 11, the shaft in the transmission case 14 and the gears to rotate the drive shafts 18a and 18b of the two endless conveyors 3a and 3b, respectively, to drive the four endless conveyors 3. .. The drive shaft 18a of the outer endless conveyor 3a and the drive shaft 18b of the inner endless conveyor 3b rotate in opposite directions.

The endless conveyors 3a, 3b driven in the reverse direction have a funnel-shaped opening into which foliage 20 such as potatoes growing on the ridges 22 are inserted, and the elastic belts 4 of the endless conveyors 3a, 3b are inserted. The foliage 20 is sandwiched at the contacting foliage withdrawing position, and the endless conveyor 3 moves as it is to move backward and upward. At this time, the foliage 20 is pressed against the elastic band 4 and can be reliably pulled out. The height of the foliage removing position is changed by changing the mounting angle of the gauge wheel 5, which is the front wheel, with the frame.

At this time, the potatoes, subterranean stems, etc. 21 of the foliage 20 to be extracted are prevented from coming out to the ground by the pressing roller 7 that presses the soil surface immediately behind the foliage extracting position. , The roots of 21 such as potatoes are torn off. Since the pressing roller 7 has a drum-like shape, it can press the surface of the ridge 22 widely, and since it is biased downward by the spring 19, the unevenness of the surface of the ridge 22 causes the frame of the foliage processing machine to be pressed. Even if the body moves up and down, the surface of the ridge 22 can always be pressed against the ground surface with an appropriate elastic force.

The separated and cut foliage 20 is directly sandwiched between the endless conveyors 3a and 3b, further sandwiched between the outer endless conveyor 3a and the auxiliary plate 5, and enters the rear foliage crushing device 10 from above to rotate. It is finely cut and crushed by the frame blade 10b. Further, the crushed foliage 20 is sown as it is in the field and used for soil improvement.
