  By the way, it is preferable that the cover body covering the rear of the tilling nail is rotatable up and down with the upper end side as a fulcrum in order to follow changes in tilling depth. When the tilling operation is performed while tilting, the outer end position in the tilt direction rotates more than necessary, and the function as a foot protection member is reduced. Further, when the cover body is rotated to the upper limit position, an excessive load is applied to the cover body, and the cover body may be damaged.

The present invention has been created in order to solve these problems in view of the above circumstances, and is provided in an airframe having an engine and a handle, an axle that is rotationally driven by engine power, and an axle. a plurality of cultivating claws, a axle cultivator type tiller and a fender for covering the upper side of the cultivating claws, the rear of the tilling claws, not covered with a cover body for vertically pivoting the upper end side as a fulcrum, the cover body When the outer end side is bent backward, the axle tillage type management machine is bent along a reference line that is inclined outward toward the upper side .
In this way, when the tilling work is performed while tilting the machine body in the left-right direction, the amount of upward rotation of the cover body is suppressed by the curved portion, so that the problem of lowering the function as the foot protection member is only solved. In addition, the cover body can be prevented from rotating to the upper limit position, and damage to the cover body can be avoided. In addition, the amount of upward rotation of the cover body can be more effectively suppressed when performing the tilling work while tilting the body in the left-right direction.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 and 2, reference numeral 1 denotes an axle tillage type management machine. The axle tillage type management machine 1 is arranged in a machine body frame 2 with a chain case 3 tilted in a front-rear and rear-high state, and an airframe. An engine 4 as a power source is mounted on the upper part of the frame 2.

  A belt transmission mechanism (not shown) that transmits power of the engine 4 to the chain case 3 and a belt cover 5 that covers the belt case 5 are provided on the upper part of the chain case 3 and the left side surface of the engine 4. A fuel tank 7 is mounted on the upper portion of the engine 4 via a stay 6, and a resin engine cover 8 that covers the periphery of the fuel tank 7 is provided.

  An axle 9 that is driven by the power output from the engine 4 protrudes left and right at the lower part of the chain case 3, and a plurality of tilling claws 10 are provided on the axle 9, and at both left and right ends of the axle 9. Are attached with disc-shaped wheels 11 respectively.

  In addition, a work machine connection hitch 12 that extends rearward is integrally connected to the rear end portion of the chain case 3. An arbitrary work machine such as a resistance bar 13 is connected to the work machine connection hitch 12. In addition, a fender 14 is provided below the engine 4 so as to prevent the mud and stones from jumping up due to the rotating tilling claws 10.

  On the other hand, a handle frame 15 protrudes from the rear portion of the chain case 3 toward the rear upper side, and handles 16L and 16R extend from the front end portion of the handle frame 15 toward the rear of the machine body. A main clutch lever 17 is provided on the left handle 16L, and a throttle lever 18 is provided on the right handle 16R.

  The left and right handles 16L and 16R are attached to the handle frame 15 via a bolt 19 with a knob so that the vertical position can be adjusted. It can be done.

  By the way, the fender 14 that covers the upper side of the tilling claw 10 is provided mainly to prevent mud and stones that are flipped up by the rotating tilling claw 10 from being applied to the engine 4 above the tilling claw 10. In order to protect the feet of the operator who operates the axle tillage type management machine 1, it is necessary to provide a cover body 20 that covers the rear of the tilling claws 10. The present invention is characterized by this cover body 20, and the cover body 20 will be described in detail below with reference to FIGS.

  The cover body 20 shown in these drawings is rotatable up and down with the upper end side as a fulcrum to follow changes in tilling depth and the like. For example, the cover body 20 of the present embodiment is connected to the rear end portion of the fender 14 via a hinge 21 and pivots up and down with the bent portion of the hinge 21 as a fulcrum. 4 and 5, reference numeral 22 denotes a mounting plate for the cover body 20, and one end side of a hinge 21 is integrally welded to the mounting plate 22. And the fender 14 are fastened together, and are fastened to the fender 14 using the fasteners 24. In addition, a stopper 22a is bent at the outer end of the mounting plate 22, and the lower limit position of the cover body 20 is defined by the stopper 22a, and contact between the cover body 20 and the tilling claw 10 is prevented. It has come to be.

  The cover body 20 rotates upward with reference to the outer end position in the tilt direction when the tilling work is performed while tilting the machine body in the left-right direction. At this time, the outer end side of the tilt direction of the cover body 20 maintains a grounded state, but the other outer end side of the cover body 20 may float from the ground, and the amount of the lift is large. The function as a foot protection member is lowered, and there is a possibility that mud and stones may be scattered at the worker's feet.

  In order to solve the above problems, in the embodiment of the present invention, the cover body 20 is divided into left and right parts, and the left and right cover bodies 20L and 20R are independently rotated. Specifically, the left and right cover bodies 20L and 20R are connected to the fender 14 via hinges 21, respectively, so that the left and right cover bodies 20L and 20R can be independently rotated. In this way, the left and right cover bodies 20L and 20R maintain the proper rotation positions even when plowing work while tilting the aircraft in the left-right direction, so that the foot protection can be achieved without significantly rising from the ground. The function as a member can be satisfactorily achieved.

  Moreover, the cover bodies 20L and 20R according to the embodiment of the present invention are formed so that the outer end side (curved portion 20a) is curved toward the rear. If it does in this way, when plowing work is performed while tilting the machine body in the left-right direction, the amount of upward rotation of the cover bodies 20L and 20R is suppressed by the curved portion 20a. In addition to being eliminated, it is possible to prevent the cover bodies 20L and 20R from rotating to the upper limit position and to prevent the cover bodies 20L and 20R from being damaged.

  In addition, the cover bodies 20L and 20R according to the embodiment of the present invention are configured to bend along the reference line L that is inclined outward as the upper side is bent rearward. For example, the outer ends of the cover bodies 20L and 20R are bent backward along the reference line L having an inclination angle of about 30 °. If it does in this way, when plowing work is performed while tilting the machine body in the left-right direction, the upward rotation amount of the cover bodies 20L and 20R can be more effectively suppressed.

  According to the present embodiment configured as described, the airframe including the engine 4 and the handle 16, the axle 9 that is rotationally driven by engine power, the plurality of tilling claws 10 provided on the axle 9, and the tilling claws 10 An axle tillage type management machine 1 including a fender 14 covering the upper side, and the outer end side of the cover body 20 is covered when the rear of the tilling claw 10 is covered with a cover body 20 that rotates up and down with the upper end side as a fulcrum. Since the vehicle is bent backward, the amount of upward rotation of the cover body 20 is suppressed by the bending portion 20a when the tilling work is performed while the machine body is tilted in the left-right direction. Thereby, not only the problem that the function as the foot protection member is deteriorated but also the cover body 20 is prevented from rotating to the upper limit position, and the damage of the cover body 20 can be avoided.

  In addition, when the outer end side of the cover body 20 is bent backward, the cover body 20 is bent along the reference line L that is inclined outward as it goes upward. The upward rotation amount of 20 can be more effectively suppressed.
