Abstract

[PROBLEMS] A uniaxial forward / reverse type is difficult for a tilling nail to bite into the soil when the ground of the field is hard, etc. and has a reversing nail, so the pulling force by the tilling nail is not sufficient, so a resistance rod is inserted deeply into the ground Even if the tillage claws were idled, it was only possible to cultivate shallowly, the boundary between the already cultivated land and the uncultivated land was difficult to understand, and it was difficult to steer because it did not generate sufficient traction.
SOLUTION: A vertically long transmission case 4 is installed in the center of the machine body, and a tilling shaft 5 having a forward rotation axis and a reverse rotation axis formed coaxially is attached to the lower output side in the left-right direction. Claw-shaped tilling claws are fixed symmetrically on the reverse rotation shaft and the forward rotation shaft on the outer side of the machine body, and the rod claws 6 are formed with a flat chisel-shaped cutting edge at the outermost ends of the forward rotation shaft. The engine 3 mounted on the fuselage was connected to the upper input side of the transmission case 4, and a resistance rod 9 was hung from the rear of the fuselage.

Description

  The present invention relates to an improvement of a walking type management work machine that performs tilling work by attaching a tilling claw to an axle.

  Conventionally, a small walking type management work machine called a forward quick tiller type with a tilling claw attached to the axle has stabbed the tip of a resistance rod attached to the back into the ground to resist the forward movement of the aircraft, While adjusting the traction force generated by the bite into the soil, the tillage claws are idled to cultivate the soil to maintain an appropriate tillage depth.

  A popular type axle is constituted by a normal rotation axis, but there is also known one in which a normal rotation axis and a reverse rotation axis are arranged coaxially. Such a uniaxial forward / reverse type has better tillage performance than the popular type, such as crushing the soil uniformly.

  On the other hand, in the uniaxial forward / reverse type, when the ground of the field is hard, the tilling nail is difficult to bite into the soil, and the retraction nail has a sufficient traction force by the tilling nail. For this reason, even if the resistance rod is deeply stabbed in the ground and the tillage claws are idled, it can only be shallowly cultivated. Therefore, there was an inconvenience that it was difficult to steer.

  In this way, the uniaxial forward / reverse rotation type is difficult for the tilling nail to bite into the soil when the ground of the field is hard and the retraction nail has insufficient pulling force by the tilling nail. Even if the tillage claws are idled, it can only be shallowly cultivated, the boundary between already cultivated land and uncultivated land is difficult to understand, and it is difficult to steer because it does not generate sufficient traction force. The idea is a problem to be solved.

  In order to solve the above-mentioned problems, as described in claim 1, a vertically long transmission case is installed in the center of the machine body, and a tilling shaft in which a forward rotation shaft and a reverse rotation shaft are formed coaxially is attached to the lower output side in the left-right direction. Of these tillage shafts, the reverse rotation shaft closer to the center of the aircraft and the forward rotation shaft on the outer side of the aircraft are fixed symmetrically to the left and right sides of the forward rotation shaft, and the tips are flattened at the outermost ends of the forward rotation shaft. A rod claw formed on the blade edge was attached radially, and the engine mounted on the fuselage was connected to the upper input side of the transmission case, and a resistance rod was hung from the tail of the fuselage.

  As described in claim 2, the rotation radius of the bar claws is made equal to the rotation radius of the tilling claws.

  As described in claim 1, since the rod claws are attached to the outermost ends of the tilling shaft, the rod claws surely bite into the ground and generate sufficient traction force in the hard ground field. Since it can stab in the ground and spin the tillage claws to break the soil uniformly with a uniaxial forward / reverse mechanism and to steer the aircraft while maintaining a constant tillage depth, it takes time to reciprocate the field many times Can be done without much labor. Furthermore, since the ground at both ends of the tillage width can be dug reliably, the boundary between the already cultivated land and the uncultivated land becomes clear, and the field can be cultivated all over without causing residual tilling.

  As described in claim 2, by making the rotation radius of the bar claw equal to the rotation radius of the claw-shaped cultivation claw, both the cultivation claw and the bar claw come into contact with the ground, and the effect of biting into the ground by the bar claw And the tillage effect of the ground by tillage claws can be obtained to the maximum.

FIG. 1 is an overall side view of a management work machine according to the present invention.
The management work machine 1 has an engine 3 mounted on a machine body frame 2, a cultivation claw 6 is attached to a cultivation shaft 5 projecting from the right and left of a transmission case 4 that extends downward from the machine body, and is steered by a handle 7 and farmed. Do work. The power from the engine 3 is transmitted to the tilling shaft 5 through the gear case 8 and the transmission case 4.

  A resistance rod 9 is attached to the rear part of the body frame 2. At the time of tillage work, the resistance rod 9 is pressed against the ground of the field, the tip is pierced into the ground, and the tillage claws 6 are idled to cultivate, and the traction force by the tillage claws 6 is adjusted to adjust the desired tillage depth. Move forward while keeping the height. At the time of non-working such as moving from the field to the field or traveling on the road, a wheel (not shown) or the like is attached to the resistance rod 9 and travels by this wheel.

FIG. 2 is a front view of the tillage working unit.
At the bottom of the transmission case 4, a reversing shaft 10 that rotates in a direction opposite to the traveling direction of the airframe is disposed near the center of the airframe, and a forward rotating shaft 11 that rotates in the same direction as the traveling direction of the airframe is coaxial with the reversing shaft 10. It is arranged outside the fuselage to form a tilling shaft. A reverse claw 12 for reverse rotation is attached to the reverse rotation shaft 10 located on both the left and right sides of the transmission case 4, and a forward claw 12 for forward rotation is attached to the normal rotation shaft 11 located outside the reverse rotation shaft 10. Further, the bar claw units 20 are attached to the outermost ends of the normal rotation shaft 11.

FIG. 3 is a side view of the bar claw unit 20.
The bar claw 21 is an L-shaped bar having a flat chisel-shaped cutting edge formed at one end, and is radially attached to the circular base 22 with the cutting edge facing outward. A ridge 23 is formed in a cylindrical shape on the base 22, and a bar claw 21 is fitted into the ridge 23 and fixed with a bolt to form a bar claw unit 20. The rotation radius of the bar claw unit 20 is set to be equal to the rotation radius of the forward claw 12 and the reverse rotation claw 12 attached to the tilling shaft 5.

  By attaching the rod claws 13 to the outermost ends of the forward rotation shaft 11, the rod claws 13 surely bite into the ground in a hard ground field while maintaining the uniform soil breaking effect of the forward / reverse rotation mechanism. Plowing can generate sufficient traction force, work with a constant plowing depth, and steer the aircraft, reducing the need to reciprocate the field many times.

  Furthermore, since the bar claws 13 are arranged at both the left and right ends of the tillage shaft 5, the ground at the both ends of the tillage width can be dug up reliably, so that the boundary between the already cultivated land and the uncultivated land becomes clear and the remaining tillage It is possible to cultivate all over the field without causing any damage.

  In order to clarify the boundary with uncultivated land, a disc-like disk (not shown) whose periphery is curved toward the center of the aircraft may be used in addition to this bar claw. No.
