Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a self-propelled type in which ridges are formed in a field and cultivated thereon, such as strawberries, onions, garlic, and butterflies, for cutting the roots of the crop. The present invention relates to a power pruning machine.

(Prior art) Conventionally, in strawberry cultivation, root cutting is performed to prevent runners. Strawberry runners are found in actively growing strawberries, and refer to the vegetative reproduction of offspring strawberries in all directions from their parent strawberries. The vegetative reproduction can be prevented by cutting the root of the parent strawberry. For onions, garlic, butterbur, etc., roots are cut off for harvesting.

For the above purpose, it has been conventionally known to perform a root cutting operation using a clipper-type cutting tooth that is slidable in the left-right direction.

(Problems to be Solved by the Invention) The root cutting operation using the known clipper-type cutting teeth is not effective in the strawberry operation during cultivation because the ridge is broken. Even in the case of onions, garlic, butterbur, etc., the ridges are similarly broken. However, since the clippers are cut by the fixed teeth and the sliding teeth, there is a problem that the wear of the teeth is remarkable and the sharpness is reduced.

Therefore, we have intensively developed a method that does not break the ridges and relatively does not reduce the sharpness.
A root cutting machine that is effective for harvesting garlic and butterbur is obtained.

(Structure of Embodiment) One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a main body case of a self-propelled root cutter, and an engine 2 is provided at a rear portion of the main body case 1. The main body case 1 also serves as a transmission case 4 for transmitting the power of the engine 2 to the root cutting portion 3.

A base of a bifurcated walking steering handle 5 is attached to the upper surface of the main body case 1. In the lower part of the main body case 1,
The left driving wheel 7 of the traveling device 6 of two left and right wheels (or four wheels is also possible) is mounted on the shaft.

The engine 2, the transmission case 4, the walking handle 5, and the left driving wheel 7 are located in a left groove 9 a of a ridge 8 formed in a field, and the right driving wheel 10 of the traveling device 6 It is located in the straddling right groove 9b.

At the front side of the transmission case 4, which is also used as the main body case 1, a base of a transmission cylinder 11 in the front-rear direction is mounted. The transmission cylinder 11 protrudes forward, and is mounted at its tip with the band tooth drive pulley 12 of the root cutting part 3 in a front-rear direction. The toothed drive pulley
Numeral 12 is located above the groove bottom of the left groove 9a.

13 is a root cutting part frame of the root cutting part 3, and
It is formed to be long in the left and right direction straddling the upper part, forming a left bent part 14 bent downward on the left side, and forming a right bent part 15 bent downward also on the right side, when viewed from the front It is formed in a mold shape.

The lower end of the left bent portion 14 is connected to the intermediate portion of the transmission cylinder 11, the lower end of the right bent portion 15 is located in the right groove 9b, and the end portion has a longitudinally-extending axial band. Passive pulley 16
, The band tooth drive pulley 12 and the band tooth passive pulley
The endless rotary band teeth 17 are looped between 16.

The lower end of the right bent portion 15 is fixed to the upper end of a leg 18 that is inclined backward as it goes down, and the right drive wheel 10 is mounted on the lower end of the leg 18. Therefore, the left driving wheel 7 and the right driving wheel 10 rotate on the same axis.

Thus, the endless rotary band teeth 17 move across the ridge 8 and cut the root of the crop A cultivated on the ridge 8. The lower turning portion 19 of the endless rotating band tooth 17 moves in the ridge 8, and the upper turning portion 20 of the endless turning band tooth 17 moves above the ridge 8. The endlessly rotating band teeth 17 are formed of a thin band steel. Note that, depending on the type of the crop A, the upwardly rotating portion 20 is expected to cut the foliage of the crop A similarly.

Reference numeral 21 denotes a guide roller for guiding the main body case 1 so as to go straight, and is axially mounted on the lower end of the arm 22 in the vertical direction.
The upper end of the arm 22 is bent rearward, and the rear end is attached to the root cutting frame 13 so as to be movable back and forth. Guide roller 21
Is provided so as to come into contact with the side surface 23 of the ridge 8 on the moving direction side (the right side in FIG. 2) of the lower turning portion 19 of the endless turning type band teeth 17, and the main body case 1 is moved by the movement of the lower turning portion 19. To prevent bending.

(Operation of Embodiment) Next, the operation will be described.

The ridges 8 are formed in the field, and the crop A is transplanted and cultivated on the ridges 8.

When the left driving wheel 7 of the main body case 1 is positioned in one of the left grooves 9a of the root cutter of the present invention, the walking operation handle 5 is located on the left groove 9a. 9a
The operator enters the vehicle and holds the walking operation handle 5 to drive while following. The right drive wheel 10 is located in the other right groove 9b, and the front guide roller 21 abuts the side surface 23 of the ridge 8 on the left groove 9a side.

Next, when the engine 2 is started, the rotation of the engine 2 causes the tooth drive pulley 12 to rotate, and the endless rotary belt tooth
Turn 17 counterclockwise as viewed from the front.

Next, the lower turning portion 19 of the endless turning type band teeth 17 is set at an appropriate depth between the upper and lower portions of the ridge 8 and the main body case 1 is advanced, and the lower turning portion 19 becomes a bulb of onions and flowers. Since the roots of the crop A are cut off, the crop A can be dug from the ridge 8 and easily harvested.

In this case, since the endless rotary band teeth 17 of the root cutting part 3 are formed of a thin band steel, even if the lower turning portion 19 of the endless rotary band teeth 17 moves in the ridge 8, the 8 can be cut without breaking the roots. In addition, the lower pivot portion 19
Therefore, the endless turning-type band teeth 17 can be used for a long period of time because they move with little horsepower and do not lose sharpness.

In addition, especially in the case of cultivation of strawberries, since the ridges 8 are not broken, the roots can be cut off, the strawberry liner can be prevented, and good strawberries can be obtained.

In the case of crops such as garlic and butterbur (parent stock), it may be better to cut the foliage in some cases.
When the root 18 cuts the root of the crop A in the ridge 8, the upper turning portion 20 of the endless rotary band tooth 17 returns to a position higher than the upper surface of the ridge 8, so that the upper turning portion 20 causes the foliage of the crop A. It is also possible to cut parts and harvest only necessary parts.

Thus, the arm 22 provided on the root cutting portion frame 13 on the moving direction side of the lower rotating portion 19 of the endless rotating belt tooth 17
Since the guide roller 21 at the lower end is in contact with the side surface 23 of the ridge 8 on the moving direction side of the lower turning portion 19 of the endless turning type belt tooth 17, the reaction force due to the movement and cutting of the lower turning portion 19 is provided. To prevent the body case 1 from moving obliquely.
Therefore, the left driving wheel 7 and the right driving wheel 10 are
23 prevents ridge collapse and helps stabilize the operability of the main body case 1.

(Effects of the Present Invention) Conventionally, in strawberry cultivation, root cutting work is performed to prevent runners. Strawberry liners are found in actively growing strawberries, and refer to the vegetative reproduction of strawberry from the parent strawberry in all directions. The vegetative reproduction can be prevented by cutting the root of the parent strawberry. For onions, garlic, butterbur, etc., roots are cut off for harvesting. For the above purpose, it has been conventionally known to perform a root cutting operation using a clipper-type cutting tooth that is slidable in the left-right direction.

However, the root cutting operation using the known clipper-type cutting teeth is not effective in the strawberry operation during cultivation because the ridge is broken. In the case of onions, garlic, butterbur, etc., the ridges are similarly broken, but moreover, since the clippers are cut by the fixed teeth and the sliding teeth, there is a problem that the teeth are significantly worn and the sharpness is reduced.

However, the present invention provides a ridge 8 formed in a field, grooves 9a and 9b formed on both sides of the ridge 8, a right and left wheel type traveling device 6 that runs in the grooves 9a and 9b, and the grooves 9a, 9b, the band drive driving pulley 12 and the band drive passive pulley 16 provided at a position above the groove bottom, and are wrapped around the drive pulley 12 and the passive pulley 16 while horizontally cutting the upper and lower intermediate positions of the ridge 8. Since it is a power root cutter consisting of the endless rotary band teeth 17 that move forward, it can be used without breaking the ridge and relatively sharply cutting, so that not only strawberry liner prevention work, but also onion
It can be used for harvesting garlic and butterbur.

In addition, since the power cutter is provided with a longitudinally rotating guide roll 21 in contact with the side surface of the ridge 8 in front of the endless rotary band teeth 17, the straightness is good, and the ridge breaking by the traveling device is performed. There is no effect.

Further, a ridge 8 formed in the field, grooves 9a and 9b formed on both sides of the ridge 8, and the main body case 1, the engine 2 and the walking control located on one of the left grooves 9a of the grooves 9a and 9b. Handle 5 and left drive wheel 7 and belt drive pulley
12, a right driving wheel 10 and a band-shaped passive pulley 16 mounted on a cutting portion frame 13 which is located on the other right-side groove 9b of the grooves 9a and 9b and is extended from the main body case 1; The ridge 8 is wound around the pulley 12 and the passive pulley 16.
