Description

  [Technical Field] The present invention relates to a glazing machine in which a trimming body composed of a polyhedron drum that is formed into a cocoon while rotating the soil raised by a pretreatment body is improved.

  Conventionally, a pre-processing body that is attached to the rear part of a traveling machine body, receives power from the traveling machine body, cultivates a part of the main fence and the field, and raises it in a bowl shape on the main fence side, and has been raised by the pre-processing body 2. Description of the Related Art A wrinkle coater including a trimming body composed of a polyhedral drum that is formed into a wrinkle while rotating soil is well known.

  As shown in FIG. 6, the polygonal drum A of the trimming body has an umbrella in which a central portion in the radial direction (center portion of the drum) is attached to the tip end portion of the rotation shaft B in the horizontal direction via the attachment portion C. It is divided into eight equal parts by a step portion (ridge line) D in the radial direction to form eight trimming surfaces E. Each trimming surface E is inclined so that the front part in the rotation (arrow) direction of the polyhedron drum A is low and the rear part is high, and when the polyhedron drum A rotates, the front half part in the radial direction (in dotted lines) (Not shown) is a non-contact surface with respect to the soil, and the latter half is a contact surface so as to be arranged. Further, the step portion (ridge line) D is substantially orthogonal to the rotation axis B.

For this reason, when the polyhedron drum A rotates and performs the trimming operation, the contact surface of each trimming surface E becomes discontinuous, comes into contact with the soil at a predetermined interval, and the vibration increases. Moreover, since the soil is in contact with the soil at a certain length in the radial direction, there is a problem that the soil adheres to the non-contact surface and the soil is protruded. Further, since the stepped portion (ridge line) D is substantially orthogonal to the rotation axis B, there is a problem that the resistance when the polyhedral drum A rotates and comes into contact with soil increases.
The present invention has been made for the purpose of solving such problems.

In order to achieve the above-mentioned object, the coating machine of the present invention is characterized by the following configuration.
A. A pre-treatment body that is attached to the rear part of the traveling machine body, receives power from the traveling machine body, cultivates a part of the main fence and the farm field, and raises it in a bowl shape on the former side, and the soil raised by the pre-treatment body In a wrinkle coater equipped with a trimming body consisting of a polyhedral drum that is formed into a wrinkle while rotating,
Each ridge line portion of the polyhedral drum has a receding angle with respect to the rotation direction.

B. Each ridge line portion of the polyhedral drum is linear with a receding angle.
C. Each ridge portion of the polyhedral drum is bent with a receding angle .

I. A. With this configuration, when the polyhedron drum rotates and strikes the soil raised by the pretreatment body, each ridge line part contacts with a receding angle with respect to the rotation direction, so that the contact resistance to the soil is reduced. Can do. Moreover, the vibration change by rotation of a polyhedral drum can be made smaller.

B. B. above. With this configuration, since each ridge line portion of the polyhedral drum is linear with a receding angle, the manufacture is relatively easy.
C. C. above. With this configuration, each ridge line portion of the polyhedral drum has a receding angle and is curved, so that the structure is somewhat complicated, but the contact resistance to the soil can be further reduced. Moreover, the vibration change by rotation of a polyhedral drum can be made smaller .

  The best mode for carrying out the present invention will be specifically described below with reference to the accompanying drawings.

  In FIG. 4, reference numeral 1 denotes a wrinkle coater which is connected to a three-point link connecting mechanism including a top link and a lower link provided at a rear portion of a tractor (not shown) and performs a trimming operation. In this wrinkle coater 1, an input unit 3 having an input shaft (not shown) that projects forward from a front frame 2 and receives power from a PTO shaft of a tractor via a universal joint and a transmission shaft is provided on the front frame 2. The top link connecting portion 4 projecting upward is provided, and the lower link connecting portions 6 and 6 are provided on the left and right via the support arms 5 and 5 so as to be connected to the three-point link connecting mechanism of the tractor.

  A transmission frame 9 also serving as a main body frame is pivotally attached to the rear ends of a pair of left and right parallel links 7 and 8 whose front ends are pivotally attached to the rear portion of the front frame 2, and can be moved (offset) to the left and right. Power is transmitted from an output shaft (not shown) protruding rearward from the input unit 3 to a transmission box 11 provided on the front side of the transmission frame 9 via a transmission shaft 10 having universal joints attached to both ends. An offset amount adjusting expansion / contraction device 12 is interposed between the position where the parallel link 7 is pivotally attached to the transmission box 11 and the parallel link 8. 16 offset amounts can be adjusted.

  On one side (right side in the drawing) of the transmission case 9 is supported by a pretreatment body 14 composed of a rotary tiller that cultivates a part of the main fence and the field and raises it in a bowl shape via a transmission case 13 extending forward. Has been. Although not shown, this pretreatment body 14 has a number of tilling claws attached to the outer periphery of a tilling shaft (work shaft) extending in the left-right direction. Further, behind the pretreatment body 14, there is provided a trimming body 16 including a polyhedral drum 19 that forms the soil, which has been plowed by the pretreatment body 14 and raised in a bowl shape, via a transmission case 15. Yes. A horizontal cylindrical body 17 is integrally provided on the outer side of the rotation center of the trimming body 16, and rotates together with the trimming body 16 to flatten the top of the bowl formed by the trimming body 16. I am trying to mold.

Here, in the present invention, the trimming body 16 composed of the polyhedral drum 19 is constituted by each trimming surface (polyhedral drum) divided into eight by a ridge line 18 as shown in FIGS. Yes. The polyhedral drum 19 is mounted by decentering a drum center side mounting portion 19a of each trimming surface attached to the mounting portion 21 provided on the center side of the drum by a predetermined amount α with respect to the drum center axis O. Yes. The polyhedral drum 19 is attached to the rotary shaft 20 with the attachment portion 21 being eccentric in the axial direction. In the first embodiment, each ridge line 18 has a straight line shape having a receding angle with respect to the rotational direction. However, as in the second embodiment shown in FIG. It is good also as the arc-shaped ridgeline 18a which it has and curves .

In the second embodiment of the present invention shown in FIG. 5, each ridge line 18 portion of the polyhedral drum 19 of the trimming body 16 in the first embodiment is linear with a receding angle. In the case of No. 2, an arcuate ridge line 18a having a receding angle in the rotation direction and bending is formed .

  In FIG. 4, a triangular disc-shaped gauge wheel 22 is supported on the other side (left side in the drawing) of the transmission case 9 by a vertical adjustment support portion 23 so that the vertical adjustment is possible. The gauge wheel 22 is formed by adjusting the vertical contact by the vertical adjustment support portion 23 to adjust the ground contact height of the entire coater 1, and adjusting the working depth of the treatment body 14 and the adjustment body 16. You can change the height of the ruins.

  The trimming body 16 is attached to the rotating shaft 20 with a slight eccentricity in the axial direction, and the eccentric amount α (runout width) can be adjusted. Further, when the polyhedron drum 19 rotates eccentrically, the trimming body 16 rotates while the polygonal ridgelines 18 and 18a (steps) and the trimming surface 19 are eccentric and strikes the gradient surface uniformly. Then, the top of the ridge is formed into a flat shape by the horizontal cylindrical body 17 to complete a new ridge.

  In the plastering machine 1 having such a configuration, the rear part of the tractor is connected via a three-point link connection mechanism, receives power from the tractor to the input part 3 and transmits the power to the transmission box 11 via the transmission shaft 10, The pretreatment body 14, the trimming body 16, and the horizontal cylindrical body 17 are driven from the transmission frame 9 through the transmission cases 13 and 15 to perform the trimming operation as the tractor travels. When the working depth of the pretreatment body 14 and the trimming body 16 is to be deep (the trimming height is increased), the gauge wheel 22 is raised upward by the vertical adjustment support portion 23, and the pretreatment body 14 and the trimming body 16. When the working depth is reduced (the adjustment height is lowered), the gauge wheel 22 is lowered downward by the vertical adjustment support portion 23. Further, the working depths of the pretreatment body 14 and the trimming body 16 are adjusted.

  When adjusting the offset amounts of the pretreatment body 14 and the trimming body 16, the parallel links 7 and 8 are moved by the expansion / contraction of the offset amount adjusting expansion / contraction device 12, and the transmission frame 9, the pretreatment body 14 and the trimming body 16 are moved. Is offset by a predetermined amount. And the working angle with respect to the machine body advancing direction of the work axis | shaft (cultivation axis | shaft in a pre-processing body) of the pre-processing body 14 and the trimming body 16 is changed.

  The pretreatment body 14 cultivates a part of the main fence and the field, and raises it in a bowl shape with respect to the main fence side, and the raised soil is a polygonal ridgeline 18 (step) of the polygonal conical drum 19 of the adjustment body 16. And the trimming surface 19 rotate while being eccentric and strike the slope to form the desired collar. In this embodiment, the working angle of the working shafts of the pretreatment body 14 and the trimming body 16 with respect to the machine body traveling direction is changed at the same time, but only the tilling shaft in the pretreatment body 14 or the rotation axis of the trimming body 16. The working angle of only 20 may be changed.

  In the trimming body 16, the drum center side mounting portion 19 a of the polyhedral drum 19 is decentered by α from the center O of the rotating shaft 20, so that the polyhedral drum 19 has a contact surface in the radial direction substantially continuously in contact with the soil. Since the rotation operation is performed, the vibration change due to the rotation of the polyhedral drum 19 is reduced. Further, the adhesion of soil to the non-contact surface of the polyhedral drum 19 and the protrusion of the soil are reduced.

  By the structure of this invention, the contact resistance with respect to the soil of a polyhedral drum becomes small. Moreover, the vibration change by rotation of a polyhedron drum becomes small, the manufacture of a polyhedron drum can be made easy, and the wrinkling machine which can form a homogeneous wrinkle can be provided.
