Description

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

  Such a hull coater is attached to the rear part of a traveling machine body such as a tractor, is driven by power from the traveling machine body, and forms a new bag on the old bag while moving along the old bag. . This padding machine mainly includes a pre-processing unit that cuts the inside of the old paddle and deposits the earth, and a padding unit that applies the soil piled up by the pre-processing unit onto the cut old paddle. .

  In such a paddy coater, when weeds grow on the upper surface of the old paddle or the upper surface of the old paddle is hard, an attempt to form a new paddle on the old paddle Since the boundary between the lantern and the Shinkan is easy to separate and the Shinkan is likely to collapse after formation, a heaven processing section that cuts off the upper surface (the heaven) of the old lantern is provided in the forward direction of the preprocessing section. As a result, a wrinkle coater has been developed that forms a new wrinkle on the top surface of an old iron that has been subjected to a field treatment (see Patent Document 1).

  As shown in FIG. 5 (front view), the coater 100 described in Patent Document 1 includes a pre-processing unit 101 (rotation center shaft 101a arranged in the extending direction of the old kite K and supported rotatably. A celestial processing unit 103 (a cutting rotor in the literature) having a rotation center shaft 103a extending in substantially the same direction as the rotation center shaft 101a of the preprocessing unit 101 is disposed on the front side of the rotation rotor. Between the front side ends of the rotation center shafts 101a and 103a of the pre-processing unit 101 and the heaven field processing unit 103, the power from the pre-processing unit 101 is transmitted to the heaven field processing unit 103 extending in the width direction of the old fence K. A transmission frame 105 (in the literature, a gear case) is provided. The transmission frame 105 is swingable in the vertical direction about the rotation center axis 101a of the preprocessing unit 101 as a rotation fulcrum, and is supported by a cover member 107 that covers the preprocessing unit 101 via the vertical position adjusting device 106. ing. That is, the transmission frame 105 is disposed at the front position of each of the heaven processing unit 103 and the preprocessing unit 101.

Japanese Examined Patent Publication No. 4-64643

  In the wrinkle coater described in Patent Document 1, the transmission frame is disposed in front of the heaven field processing unit and linearly extends in a substantially horizontal direction toward the wrinkle side. For this reason, when the height of the old saddle is high, the transmission frame may be in contact with or placed adjacent to the old saddle. In such a case, if the padding machine moves forward, the soil hits the front part of the transmission frame, and every time the transmission frame gets over the hit soil, the transmission frame swings upward, making it impossible to perform desired heaven treatment. A problem occurs.

  In addition, the gap between the transmission frame and the old fence is narrow, and part of the soil that has been subjected to the heaven treatment by the heaven treatment unit tends to accumulate on the front side in the traveling direction of the transmission frame. As a result, the movement of the earth-treated soil to the pre-treatment unit side is suppressed, and the amount of soil to be accumulated is reduced and cannot be sufficiently compacted.

  In addition, old dredged soil accumulates on the front side of the transmission frame, and the vehicle travels forward while pushing these soils. As a result, there is a problem in that the traction resistance is increased, the work stability is lowered, and the glazing performance such as the bending of the new heel is lowered.

  The present invention has been made in view of such a problem, and provides a coater capable of stably performing a coat-coating operation in a high-performance state without the possibility of soil collecting in front of the transmission frame. The purpose is to do.

  In order to achieve the above-described object, the plastering machine of the present invention is mounted on a traveling machine body, arranged at a position offset laterally with respect to the traveling position of the traveling machine body, and a celestial process that cuts off the heaven field of the old fence. Power transmission frame for transmitting power to the heaven field processing unit in a slag coater with a pre-processing unit that cuts and fills the old culvert and a trimming unit that coats the piled soil on the crushed old culvert For example, the heavenly power transmission frame 52) in the embodiment is provided at the front end portion of the pretreatment portion so as to be rotatable in the vertical direction, and extends so as to have a shape substantially along the cross-sectional shape of the old iron. A space portion is formed between the heavens and the inner surface.

  According to the present invention, the transmission frame is provided at the front end of the pre-processing portion so as to be rotatable in the vertical direction, and has a shape that substantially conforms to the cross-sectional shape of the old casket. By forming a space part between the side surfaces, the transmission frame and the old paddle are not in contact, and when the padding machine advances, Smoothly sent to the preprocessing side. For this reason, there is no possibility that soil accumulates in front of the transmission frame, and most of the earth-processed soil is supplied to the pretreatment unit, so that it is possible to stably perform the mortaring operation with high performance. Further, since the transmission frame has a shape that substantially conforms to the cross-sectional shape of the old fence, when the transmission frame is disposed behind the celestial processing unit in the traveling direction, a space formed above the celestial field. And the direction of the flow as a flow path for flowing the soil cut by the heaven field processing unit can be smoothed by the space part formed on the side of the inner surface of the old fence. For this reason, the earth-processed soil can be reliably supplied to the pretreatment unit side.

  The transmission frame of the present invention has at least two members, and an intermediate portion of the transmission frame is further rotatable in the vertical direction.

  According to the present invention, the transmission frame has at least two members, and the middle portion of the transmission frame is further rotatable in the vertical direction, so that the middle of the transmission frame can be adjusted according to the height of the old fence. By rotating the part, the space part can be formed in a desired shape, and it is possible to reliably avoid contact between the transmission frame and the old iron, and the transmission frame is arranged on the rear side in the traveling direction with respect to the heaven field processing part. In the case where it is provided, the soil cut by the heaven processing unit can surely flow to the preprocessing unit side.

  According to the scissor coating machine according to the present invention, the transmission frame is provided at the front end portion of the pretreatment portion so as to be rotatable in the vertical direction, and extends so as to have a shape substantially along the cross-sectional shape of the old scissors. By forming a space between the heaven and the inner surface, soil does not collect in front of the transmission frame, and most of the heaven-treated soil is supplied to the pretreatment section, so It is possible to provide a coater that can be stably performed in a high performance state.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a wrinkle coater according to the present invention will be described below with reference to FIGS. The present embodiment will be described with reference to an example of a scissoring machine that performs a smearing operation in accordance with forward travel of the traveling machine body. For convenience of explanation, the following description will be made assuming that the directions of arrows shown in FIG. 1A (plan view) are the front-rear direction and the left-right direction.

  As shown in FIGS. 1 (a), 1 (b) (viewed from the arrow A) and FIGS. 2 (c) (side view), (d) (front view), the wrinkle coater 1 is provided at the rear portion of the traveling machine body 90. It is connected to the three-point link connecting mechanism (not shown), and proceeds according to the forward traveling of the traveling machine body 90. The wrinkle coater 1 is mounted on the traveling machine body 90 and left and right from the mounting part 10 by a mounting part 10 having an input shaft 15a to which power from the traveling machine body 90 is input and a turning cylinder 11 provided on the mounting part 10. An offset mechanism 20 that is movable in the direction, and a rotation center axis of a rotation drive shaft 21 that extends in the vertical direction on the moving end side (rear end side) of the offset mechanism 20 is disposed so as to be rotatable in the horizontal direction. And a working unit 30 that performs an offset work with the power transmitted from the input shaft 15a.

  The mounting portion 10 includes a hitch frame 12 that extends in the left-right direction, and a connection frame (not shown) that is attached to the front side of the hitch frame 12 and can be connected to the three-point link connection mechanism of the traveling machine body 90. A gear box 15 is provided at the lower center of the hitch frame 12 in the left-right direction. The gear box 15 is provided with the input shaft 15a described above. The input shaft 15a is configured to transmit power from a PTO shaft (not shown) of the traveling machine body 90 via a transmission shaft (not shown).

  The offset mechanism 20 is rotatably connected to the hitch frame 12 on the front end side and extends rearward, and is arranged along the right side of the offset frame 22 so that the front end side is on the right end of the hitch frame 12. It has the link member 23 connected so that rotation was possible. The rear end side of the link member 23 is rotatably attached to a connecting arm member 25 connected to a connecting member 24 provided rotatably at the rear end portion of the offset frame 22. The offset mechanism 20 forms a parallel link mechanism by the offset frame 22, the link member 23, the hitch frame 12, and the connecting arm member 25.

  The offset frame 22 can be swung in the left-right direction by the expansion and contraction of the revolving cylinder 11 described above, and is provided on the rear end side of the offset frame 21 via a power transmission mechanism (not shown) provided in the offset frame 22. A driven shaft (not shown) extending in a substantially vertical direction is rotationally driven. Under the driven shaft, the above-described rotary drive shaft 21 serving as a rotation center axis of the working unit 30 is coaxially connected to the driven shaft.

  A rotation shaft case 32 is provided outside the rotation drive shaft 21 to cover it. An upper end portion of the rotary shaft case 32 is rotatably connected to a lower end portion of the offset frame 21, and is attached to a lower end portion of the rotary shaft case 32 with the working unit 30 fixed. In addition, the connecting member 24 described above that is rotatable with respect to the rotating shaft case 32 is provided on the rotating shaft case 32. That is, the connecting member 24 is in a non-coupled state with the rotation shaft case 32 and the rotation drive shaft 21 and is rotatable about the rotation drive shaft 21 as a rotation center. The connecting arm member 25 is connected to the connecting member 24 and extends in the lateral direction.

  The working unit 30 rotates with the rotation center axis of the rotation drive shaft 21 as a rotation fulcrum (hereinafter referred to as a rotation fulcrum O) by the connection mechanism 40 connected between the connection arm member 25 and the rotation shaft case 32. In addition to being movable, the connecting mechanism 40 holds the working direction axis O2 indicating the working direction of the working unit 30 with respect to the swing of the offset mechanism 20 so as to be parallel to the traveling direction B of the traveling machine body 90. Here, the connecting mechanism 40 includes a connecting member 24 and an expansion / contraction cylinder (not shown), and the expansion / contraction cylinder is pivotally connected between the distal end portion of the connection arm member 25 and the upper portion of the rotary shaft case 32. Has been. For this reason, when the telescopic cylinder expands and contracts, the working unit 30 rotates about the rotation fulcrum O via the connecting arm member 25 as the rotation center. The rotation angle range of the working unit 30 is set according to the stroke size of the telescopic cylinder. For this reason, when the telescopic cylinder having a large stroke is used, the working unit 30 can be moved in a state where the direction is reversed from one side of the left and right sides of the traveling machine body 90 to the other side.

  Further, when the expansion / contraction operation of the expansion / contraction cylinder is restricted in a state in which the operation direction axis O2 of the operation unit 30 extends in parallel in the front-rear direction, the connection mechanism 40 integrates the operation unit 30 and the connection member 24. Therefore, when the offset mechanism 20 is swung in the left-right direction in a state where the working unit 30 and the connecting member 24 are integrated, the working unit 30 connects the connecting arm member 25 of the offset mechanism 20 constituting the parallel link mechanism. The working direction axis O2 of the working unit 30 moves while being maintained parallel to the front-rear direction via the connecting member 24 connected to the head.

  As shown in FIG. 3 (plan view), the movable working unit 30 is configured by arranging the celestial processing unit 50, the preprocessing unit 60, and the trimming unit 70 from the front side. The Tenba processing unit 50 cuts the upper part (Tenba) of the old paddle formed along the periphery of the paddy field, the pre-processing unit 60 performs the filling of the cut soil, and the trimming unit 70 cuts the piled soil. It has the function of painting on the broken old wall.

  The trimming unit 70 includes a polyhedral drum 73 attached to a rotation center shaft 71 that extends in the left-right direction and is rotatably supported, and a cylindrical portion 75 that is attached to the right end of the polyhedral drum 73 and extends in the lateral direction. It has. The trimming unit 70 is connected to and supported by the rotary shaft case 32 via a trimming power transmission case 77. An adjustment power transmission mechanism (not shown) is built in the adjustment power transmission case 77, and the adjustment power transmission mechanism is connected to the rotation drive shaft 21, and the power from the rotation drive shaft 21 is adjusted to the adjustment power. It is transmitted to the trimming unit 70 via the transmission mechanism.

  The preprocessing unit 60 includes a preprocessing rotor 61 that is rotatable. The pretreatment rotor 61 is connected to and supported by the rotary shaft case 32 via a pretreatment power transmission case 64. In the preprocessing power transmission case 64, a preprocessing side power transmission mechanism 65 having a preprocessing side drive shaft 66 that rotates by receiving power from the rotary drive shaft 21 is incorporated. A pretreatment rotor 61 is inserted into the tip of the pretreatment side drive shaft 66. The rotation center shaft 62 of the pretreatment rotor 61 is disposed coaxially with the pretreatment side drive shaft 66. The pretreatment rotor 61 is arranged so that the rotation center axis 62 thereof extends in a direction intersecting with the rotation center axis 71 of the trimming unit 70 in plan view. For this reason, when the rotation center shaft 71 of the trimming portion 70 is arranged in a direction substantially orthogonal to the direction in which the old rod K extends, the rotation center shaft 62 of the pretreatment rotor 61 is inclined with respect to the direction in which the old rod K extends. Will be placed in the direction.

  The celestial processing unit 50 includes a celestial processing rotor 51 that is rotatable. The heaven processing rotor 51 is supported by the preprocessing rotor 61 via the heaven power transmission frame 52. The celestial processing rotor 51 has a plurality of celestial processing claws 54 attached radially to a rotation center shaft 53 thereof. The celestial processing claw 54 extends straight at the base end side, and the tip end side is bent laterally to scrape off the upper part of the old hook. The celestial processing rotor 51 is disposed in a direction in which the rotation center axis 53 intersects the rotation center axis 71 of the trimming unit 70 in a plan view, that is, in a direction extending substantially parallel to the rotation center axis 62 of the pretreatment rotor 61. ing. For this reason, when the rotation center shaft 71 of the trimming portion 70 is arranged in a direction orthogonal to the direction in which the old rod K extends, the rotation center shaft 53 of the heaven field processing rotor 51 is oblique to the direction in which the old rod K extends. Will be placed in the direction.

  The celestial power transmission frame 52 is disposed between the celestial processing rotor 51 and the preprocessing rotor 61 and extends in a direction orthogonal to the rotation center axis 53 of the celestial processing rotor 51. The side view shape of the heavenly power transmission frame 52 will be described later. The heavenly power transmission frame 52 has a base end attached to a connecting shaft 63 extending from the tip end of the rotation center shaft 62 of the pretreatment rotor 61 so as to be rotatable in the vertical direction and fixed to the rotary shaft case 32. It is supported through a vertical position adjusting device 35 shown in FIG. For this reason, the celestial processing rotor 51 can be rotated in the vertical direction with the connecting shaft 63 as a rotation center. As a result, when the celestial processing claw 54 comes into contact with a large stone or the like and the rotational motion of the celestial processing rotor 51 is to be restricted, the celestial processing rotor 51 moves upward to rotate the celestial processing rotor 51. Is acceptable. For this reason, interruption of the smearing operation can be prevented in advance, and the smearing operation can be performed continuously.

  A heaven power transmission mechanism 55 is provided in the heaven power transmission frame 52. This celestial-side power transmission mechanism 55 is a chain transmission type, and includes a drive sprocket 55a provided on the connecting shaft 63, a driven sprocket 55b provided on a driven shaft 56 connected to the rotation center shaft 53 of the heavenly processing rotor 51, There are intermediate sprockets 56c and 56d provided in the intermediate part of the heavenly power transmission frame 52, chains 55e and 55f spanned between the drive sprocket 55a and the intermediate sprocket 56d and between the intermediate sprocket 56c and the driven sprocket 55b, Power from the pretreatment rotor 61 is transmitted to the heaven treatment rotor 51. The heaven-side power transmission mechanism 55 may be a gear transmission type.

  As shown in FIG. 4 (side view), the heaven power transmission frame 52 forms a space 80 between the heaven field and the inner side surface of the old fence K and extends to the old fence K side. More specifically, the heavenly power transmission frame 52 includes a first frame portion 52a extending obliquely upward from the connecting shaft 63 connected to the preprocessing portion 60 in the side view to the old heel K side, and a distal end portion of the first frame portion 52a. And a second frame portion 52b extending obliquely downward. The first frame portion 52a extends along the inner surface Ks of the old fence K, and the second frame portion 52b extends along the heaven field Kt of the old fence K. By forming the celestial power transmission frame 52 in this way, the area of the space portion 80 indicated by the two-dot chain line formed between the celestial power transmission frame 52 and the old kite K can be widened. It is possible to surely avoid contact between the heaven field power transmission frame 52 and the old fence K, and to change the extending direction of the space 80 serving as a flow path for flowing the soil cut by the heaven field processing unit 50. Can be smooth. For this reason, the earth-processed soil can be reliably supplied to the preprocessing unit 60 side.

  Next, the operation of the hull coater 1 will be described using a case where one side of the paddy field is hulled as an example. As shown to Fig.1 (a), the traveling body 90 is first arrange | positioned so that the one side Sa of the paddy field S may be met. Then, the telescopic cylinder of the coupling mechanism 40 is expanded and contracted so that the working direction axis O2 of the working unit 30 is parallel to the traveling direction of the traveling machine body 90, and the expansion and contraction operation of the telescopic cylinder is restricted. As a result, the working unit 30 is integrated with the connecting member 24 and the rotating shaft case 32 shown in FIG. When the offset mechanism 20 that forms the parallel link mechanism is swung to the right side, the working unit 30 is held in parallel with the front-rear direction, and the working unit 30 is capable of performing a smearing operation by forward traveling of the traveling machine body. Move to working position.

  Then, the traveling machine body 90 is moved forward and the working unit 30 is driven. When the working unit 30 is driven while traveling forward, as shown in FIG. 3, the heaven processing unit 50 cuts off the upper part (heaven) of the old paddle K on one side Sa of the paddy field S, and the preprocessing unit 60 cuts down. The soil is piled up, and the soil on which the trimming unit 70 is piled is applied onto the cut old paddle K, and one side Sa of the paddy field S is continuously padded.

  Here, the soil subjected to the heaven treatment by the heaven treatment rotor 51 is blown toward the paddy field S side and passes through the space 80 shown in FIG. 4 formed below the heaven power transmission frame 52. Fall into the paddy field S. As described above, the space 80 is wide and the heaven power transmission frame 52 and the old fence K do not come into contact with each other, and the heaven power transmission frame 52 is disposed behind the heaven processing unit 50 in the traveling direction. In this case, since the space 80 has a smooth change in direction as a flow path for flowing the soil cut by the heaven field processing unit 50, the old space part cut by the heaven field processing unit 50 is used. There is no fear that the heavenly soil of 畦 K accumulates in front of the celestial power transmission frame 52, and most of the soil subjected to the celestial treatment can be supplied to the preprocessing unit 60. For this reason, desired celestial processing can be performed.

  Then, the pretreatment rotor 61 performs soil filling of the soil cut from the old paddle K and the soil subjected to heaven treatment. That is, the pretreatment rotor 61 is piled up on the old culvert that has been cut by a sufficient amount of soil. Then, the trimming unit 70 applies the piled soil onto the old crushed K. For this reason, it is possible to stably perform the smearing operation with high performance.

  In the above-described embodiment, the celestial power transmission frame 52 is integrally formed. However, the celestial power transmission frame is configured to include at least two box-shaped members. You may comprise the intermediate part of a transmission frame so that rotation is possible to an up-down direction. By configuring the heaven power transmission frame in this way, the space portion can be formed in a desired shape by rotating the intermediate portion of the heaven power transmission frame according to the height of the old fence K, and reliably Contact between the heavenly field power transmission frame and the old fence can be avoided, and the heavenly-treated soil can be reliably supplied to the pretreatment unit 60 side.

  In the above-described embodiment, the heaven field processing unit 50 and the preprocessing unit 60 are arranged such that the extending directions of the rotation center axes 53 and 62 of the heaven field processing unit 50 and the preprocessing unit 60 intersect with those of the rectifying unit 70. Although the case where it arrange | positions was shown, the celestial processing part 50 and pre-processing so that the extending direction of each rotation center axis | shaft 53 and 62 of the celestial processing part 50 and the pre-processing part 60 may become substantially parallel to that of the shaping part 70. The part 60 may be arranged. Even when the celestial processing unit 50 and the preprocessing unit 60 are arranged in this manner, the same effects as those of the above-described embodiment can be obtained.
