Description

  The present invention relates to a cocoon work machine that forms a new rice cake by repairing an old rice cake that partitions a paddy field.

  Such a hulling machine is known in which a working unit is arranged at a position offset laterally with respect to the traveling position of the traveling machine body, and the hulling work is performed while proceeding with the forward movement of the traveling machine body. (See Patent Document 1). The hulling work by this hulling machine (literature machine in the literature) is performed by the forward movement of the traveling machine body. Therefore, when the front end of the traveling machine body reaches the end of the field, the length of the traveling machine body in the substantially front-rear direction is increased. There will be some unpainted areas.

  For this reason, there has been proposed a lacquering machine that enables lacquering of unpainted old cocoons (see Patent Document 2). This glazing machine (in the literature, a lacquering machine) supports the pretreatment body and the trimming body by a single transmission frame, and allows the transmission frame to be rotated by 180 degrees. ) And the lacquering machine back, enabling the lacquering operation to the end. In order to perform the finishing operation to the edge with the thus-configured finishing machine, the driving of the pretreatment body and the finishing body is stopped, and the finishing machine is moved by the three-point link mechanism of the traveling body. Lift and rotate the transmission frame to move the pre-processing body and trimming body to the reverse offset work position, and retreat the traveling machine body to the side to shape the heel and move the work equipment to perform the glazing work Make it. In this way, when performing the dredging work at the time of dredging, it is necessary to temporarily stop the normal fringing work for performing the fringing work while moving the traveling machine forward, and the workability of the entire dredging work is reduced. However, since operations such as reversing the pretreatment body and the trimming body are necessary, there is a problem that operability is poor.

  Therefore, a plastering work machine (in the literature, an offset work machine) that solves these problems has been proposed by the present applicant (see Patent Document 3). The working machine includes an offset position adjusting mechanism capable of adjusting an offset position of the working unit, a working direction adjusting mechanism capable of rotating and adjusting a working direction of the working unit, and a reference work line serving as a reference of the working direction of the working unit, Operation of the offset position adjustment mechanism and the work direction adjustment mechanism so that the work position and the work direction of the work part are along the work reference line according to the detection value of the work part, and the detection means for detecting the positional relationship with the work part And control means for controlling.

Can be rotated in the horizontal direction. The rotating cylinder 14 has one end pivoted to the working unit 20 and the other end pivoted to the connecting arm member 31. For this reason, when the offset mechanism unit 10 swings in the left-right direction in a state where the expansion / contraction operation of the rotating cylinder 14 is restricted, the work direction axis O2 indicating the work direction of the work unit 20 is kept constant and the work is performed. The unit 20 can be offset.

  The working unit 20 connected in this way forms a new paddle by cutting a side portion of the old paddle, repelling the old paddle, and depositing the soil on the old paddle. The pretreatment body 21 includes a pretreatment rotor 22 as shown in FIG. 3 (bottom view). The pretreatment rotor 22 includes a rotary shaft 23, a plurality of tilling claws 24 that are attached to the rotating shaft 23, and a protruding claw 25, and a cover 26 that covers the top of the tilling claw 24 and the protruding claw 25.

The pretreatment power transmission case 52 extends forward from the drive shaft case 11, and the cover 26 of the pretreatment body 21 is disposed below the gear box 6 provided at the lower portion of the mounting portion 5.

  As shown in FIG. 4 (cross-sectional view), the trimming body 40 is supported by a trimming power transmission case 54 attached to an intermediate portion of the pretreatment power transmission case 52, and the tip of the trimming power transmission case 54 is A polyhedral drum 41 rotatably attached to the portion, and a cylindrical portion 44 attached to the right end of the polyhedral drum 41 and extending in the lateral direction. The straightening power transmission case 54 includes an arm portion 54a having one end connected to a branch case 53 provided at an intermediate portion of the pretreatment power transmission case 52 and extending rearward, and a lateral direction from the rear end side of the arm portion 54a. And a support portion 54b extending in the direction. Most of the trimming power transmission case 54 is disposed inside the polyhedral drum 41. For this reason, the trimming body 40 and the pretreatment body 21 can be disposed close to each other, and the working unit 20 can be configured compactly.

  In the above-described example, as shown in FIG. 1, the offset mechanism unit 10 includes a transmission link 15 and a parallel link mechanism having a link member 17 and a swing cylinder 16. A parallel link frame that transmits power via the oscillating cylinder 16 and the swing cylinder 16 may be used. Further, as the swing cylinder 16, a hydraulic cylinder, an electric cylinder, or the like can be used.

  Next, a power transmission mechanism unit that transmits power to the pretreatment body 21 and the trimming body 40 of the working unit 20 will be described. As shown in FIG. 4, the power transmission mechanism 50 includes a power transmission shaft 51, a first transmission mechanism 60 that transmits power from the power transmission shaft 51 to the pretreatment body 21 and the trimming body 40, A power branching portion 65 that extracts a part of the power transmitted to the transmission mechanism portion 60 and a second transmission mechanism portion 70 that transmits the power from the power branching portion 65 to the trimming body 40 are provided.

  The first transmission mechanism 60 is a shaft transmission mechanism, and includes a preprocessing power transmission shaft 61 that is rotatably supported in the preprocessing power transmission case 52 and extends in the horizontal direction. One end side of the pretreatment power transmission shaft 61 is connected to the power transmission shaft 51 through a gear mechanism 62 so as to be able to transmit power, and the other end side of the pretreatment power transmission shaft 61 is connected to the rotary shaft 23 of the pretreatment rotor 22. It is connected. The rotary shaft 23 is attached to the front end of the pretreatment power transmission shaft 61 coaxially with the pretreatment power transmission shaft 61. For this reason, when the power transmission shaft 51 rotates, the power from the power transmission shaft 51 is transmitted to the rotary shaft 23 via the pretreatment power transmission shaft 61, and the pretreatment rotor 22 can be rotated.

  The power branch portion 65 is a shaft transmission mechanism, and is housed in a branch case 53 formed by branching to an intermediate portion of the pretreatment power transmission case 52, and is attached to the pretreatment power transmission shaft 61. A bevel gear 66, a branch transmission shaft 67 rotatably supported in the branch case 53, and a second bevel gear 68 that is attached to the branch transmission shaft 67 and meshes with the first bevel gear 66. Become. The power branching portion 65 is disposed inside the polyhedral drum 41 of the trimming body 40, and the distal end portion of the branch transmission shaft 67 is disposed inside the polyhedral drum 41.

  The second transmission mechanism unit 70 includes a chain transmission mechanism 71 provided in the arm portion 54a of the trimming power transmission case 54 attached to the distal end portion of the branch case 53, and the trimming body 40 from the distal end portion of the arm portion 54a. And a shaft transmission mechanism 72 provided in a support portion 54b extending to the rotating shaft 42 side. The arm portion 54a extends from the inner end portion of the polyhedral drum 41 toward the central portion. A transmission shaft 73 extending in the horizontal direction is rotatably supported in the support portion 54 b, and the rotation shaft 42 of the trimming body 40 is coaxially connected to the transmission shaft 73 at this tip portion. For this reason, the power transmitted to the power transmission shaft 51 is transmitted to the rotating shaft 42 of the trimming body 40 via the first transmission mechanism portion 60 → the power branch portion 50 → the second transmission mechanism portion 70, so The body 40 can be rotated.

  Next, the positional relationship among the power transmission shaft 51, the pretreatment body 21, and the trimming body 40 will be described. The power transmission shaft 51 is arranged coaxially with the vertical axis passing through the intersection O ′ between the rotation center axis of the trimming body 40 and the rotation center axis of the pretreatment body 21. The power transmission shaft 51 is the rotation fulcrum O of the working unit 20. That is, in plan view, the rotation fulcrum O of the working unit 20 is disposed on the intersection point O ′ between the rotation center axis of the trimming body 40 and the rotation center axis of the pretreatment body 21. In the pretreatment body 21 and the trimming body 40, the angle formed by the rotation center axis of the trimming body 40 and the extending direction of the tilling claws 24 of the pretreatment body 21 is an acute angle (for example, about 10 ° to 30 °). , Preferably 25 °).

  As described above, the rotation fulcrum O of the working unit 20 is provided on the rotation center axis of the trimming body 40 and the pretreatment body 21 in plan view, and the power branching unit 65 of the power transmission mechanism unit 50 is located more than the rotation fulcrum O. By providing the traveling machine body 90 on the front side in the traveling direction, the pretreatment body 21 and the trimming body 40 constituting the working unit 20 and the power transmission mechanism unit 50 for transmitting power to these are arranged on the traveling machine body side. And the center of gravity of the working unit 20 can be moved to the traveling machine body side. Therefore, as shown in FIG. 1, when the offset mechanism unit 10 is extended rearward, the work direction axis O2 of the working unit 20 is set along the offset mechanism unit 10 and the padding work machine 1 is in the retracted movement state. The position of the center of gravity of the hull coater 1 can be moved further toward the traveling machine body. Accordingly, it is possible to improve the front-rear balance between the traveling machine body 90 and the hulling work machine 1 during movement.

  Further, by setting the intersection O ′ of the rotation center axes of the trimming body 40 and the pretreatment body 21 as the rotation fulcrum O of the working unit 20, the offset mechanism unit 10 moves during the work and the working unit 20 and the traveling machine body are moved. Even if the distance from 90 changes, the gravity center positions of the pretreatment body 21 and the trimming body 40 move around the rotation fulcrum O with a constant radius, and therefore the degree of instability of the posture of the hulling machine itself Can be further suppressed. For this reason, it is possible to perform an accurate hull shaping operation at the time of haze painting.

  Further, as shown in FIG. 4, the power transmission shaft 51 is arranged coaxially with the vertical axis passing through the intersection O of the rotation center axes of the trimming body 40 and the pretreatment body 21, thereby rotating the working unit 20. Therefore, it is possible to share the parts of the rotating mechanism 13 and the power transmission mechanism 50 that transmits power to the working unit 20, and the working unit 20 can be reduced in size and weight.

  Further, the pre-processing power transmission shaft 61 connected to the pre-processing rotor 22 is connected to the power transmission shaft 51 so as to be able to transmit power and extends to the front side in the traveling direction, via a power branching portion 65 provided on the pre-processing power transmission shaft 61. By transmitting the power of the trimming body 40, a part of the power transmission mechanism 50 that transmits power to the pretreatment body 21 and the trimming body 40 can be shared by the pretreatment power transmission shaft 61. The structure of the transmission mechanism part 50 can be reduced in size.

  Further, since the power branching portion 65 is disposed inside the polyhedral drum 41 and the second transmission mechanism portion 70 is disposed in the polyhedral drum 41, the space between the pretreatment body 21 and the trimming body 40 can be effectively utilized. Arrangement is possible, and the working unit 20 can be further downsized. In addition, by adjusting the angle formed by the pretreatment body 21 and the trimming body 40, even if the diameter of the pretreatment body 21 is reduced, it is possible to perform the smearing operation with substantially the same accuracy as before.
