Description

  The present invention relates to a tack coater, and more particularly, to a tack coater that includes a pre-processing unit that cuts an old kite and deposits soil, and a trimming unit that coats the soil deposited thereby on the old kite.

  The hull coater is attached to the rear part of a traveling machine body such as a tractor, and is driven by the power transmitted from the traveling machine body while traveling along with the traveling of the traveling machine body to perform a hulling operation. In such a hull coater, a pre-processing unit having a plurality of tilling claws radially provided on a rotary drive shaft that is supported so as to be rotatable in the extending direction of the old hail, and the progress of the hulling machine more than the pre-processing unit There is an arrangement including a rectifying portion disposed on the rear side in the direction and having a rotation center axis inclined toward the heel side and extending in the vertical direction and supported so as to be rotatable (see Patent Document 1).

  This pre-processing unit jumps up the soil cut out from the field scene at the shore and the old culvert and raises it into the old culvert. On the other hand, the trimming section has a continuous line segment facing the upper surface of the old iron and the inner surface of the old iron as a bus, and has a rotation center axis that extends in the vertical direction inclined to the old iron side and is supported rotatably. An upper rotating body portion having a peripheral surface capable of adjusting the upper surface of the old iron and a lower surface connected to the lower portion of the upper rotating body portion and extending downward to adjust the inner surface of the old iron And a lower rotating body portion having The generatrix direction of the side surface of the upper rotating body portion extends substantially parallel to the upper surface of the collar, and the generatrix direction of the peripheral surface of the lower rotating body portion extends approximately parallel to the inner surface of the old carcass. For this reason, when the pretreatment unit and the trimming unit rotate, the soil raised to the old kite by the pretreatment unit is trimmed into a shape along the generatrix by the trimming unit.

JP-A-8-308307

  In this conventional wrinkle coater, the generatrix direction of the peripheral side surface of the upper rotating body portion extends substantially parallel to the upper surface of the upper rotating body portion, but the vertical position thereof does not change regardless of the rotation of the upper rotating body portion. For this reason, the tightening condition of the upper surface of the old iron is influenced by the amount of the soil piled up on the old paddle, and if the amount of the piled up soil is small, the upper surface of the new paddle to be formed becomes brittle. Also, since the position in the left-right direction of the generatrix of the peripheral surface of the lower rotator is not changed regardless of the rotation of the lower rotator, the soil that is piled up on the old fence is the same as in the case of the upper rotator If the amount is too small, the inner surface of Xinjiang becomes brittle.

  In addition, the pre-processing unit cuts out the soil in the field at the shore and hops it up toward the old culvert.However, if the surface of the field is dry, the soil in the old culm will be less moistened and tightened. Can not mold good Xinjiang. In other words, the conventional wrinkle coater has a problem that the brittleness of the new rice cake to be formed varies greatly depending on the wet conditions in the field, and new rice cake with good tightness cannot always be formed.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a coater that can always form a new koji with good tightening without being affected by the wet condition of the field.

  In order to solve this problem, the present invention provides a pretreatment unit that is attached to the rear part of a traveling machine body and cuts an old paddle to pile up the soil, and the soil piled up by the pretreatment unit is applied to the cut old paddle. In a scissor coating machine that performs scissoring work by driving the pre-processing unit and the scoring unit with the power transmitted from the traveling machine body, the scoring unit has a rotation center axis extending vertically. An upper rotating body portion having a first circumferential surface that is supported so as to be capable of rotating and that can arrange the upper surface of the old iron, and a first rotating body that is disposed below the upper rotating body portion and is capable of adjusting one side surface of the old iron. A lower rotating body portion having two circumferential surfaces, and the first circumferential surface of the upper rotating body portion has a direction that extends radially outward with respect to the rotation center axis according to a rotation angle of the adjusting portion. It is characterized by becoming.

  According to the present invention, the trimming portion is rotatable about the rotation center axis extending in the vertical direction as a rotation center, and the upper rotating body portion having the first circumferential surface that trims the upper surface of the old rod, A lower rotating body portion having a second circumferential surface that trims one side surface of the collar, and the first circumferential surface has a radially extending direction that changes according to the rotation angle of the trimming portion, When the trimming part rotates, the first circumferential surface moves up and down while rotating. For this reason, the soil piled up on the old fence can be pressed by the first peripheral surface to form a tight upper face of the fence.

  In addition, the present invention includes a pre-processing unit that is attached to the rear part of the traveling machine body and cuts the old iron to fill the earth, and a trimming unit that applies the soil piled up by the pre-processing unit to the old iron that has been cut. In the wrinkle coater that performs the wrinkling operation by driving the pre-processing unit and the wrinkle unit with the power transmitted from the traveling machine body, the rotation center axis of the wrinkle unit is relative to the drive shaft of the wrinkle unit It is characterized by being eccentric.

  According to the present invention, the rotation center axis of the trimming section is eccentric with respect to the drive axis of the trimming section, so that when the drive shaft of the trimming section rotates, the rotation center axis of the trimming section Rotates while swinging, and the second peripheral surface moves toward and away from one side surface of the old saddle while rotating. For this reason, the soil piled on the old ridge is pressed onto the upper surface of the heel that is pressed by the first circumferential surface and pressed onto one side surface of the old ridge by the second peripheral surface, and is one side surface that is tightened Molded. For this reason, it is possible to form a new roll that is tight as a whole.

  In addition, the present invention includes a pre-processing unit that is attached to the rear part of the traveling machine body and cuts the old iron to fill the earth, and a trimming unit that applies the soil piled up by the pre-processing unit to the old iron that has been cut. In a wrinkling machine that drives the pre-processing unit and the leveling unit with the power transmitted from the traveling machine body, the leveling unit is supported so that the rotation center axis extends in the vertical direction and can rotate. And an upper rotating body portion having a first circumferential surface capable of trimming the upper surface of the old hammer, and a second circumferential surface disposed below the upper rotating body portion and capable of trimming one side surface of the old hammer. And a first circumferential surface of the upper rotating body portion, the direction extending radially outward with respect to the rotation center axis is changed according to the rotation angle of the adjusting portion, The rotation center axis is eccentric with respect to the drive axis of the trimming unit.

  According to the present invention, the trimming portion includes the upper rotating body portion having the first circumferential surface and the lower rotating body portion having the second circumferential surface, and the first circumferential surface of the upper rotating body portion is radially outward. The extending direction changes according to the rotation angle of the trimming section, and the rotation center axis of the trimming section is decentered with respect to the driving axis of the trimming section, so that the first rotation The surface moves up and down and moves up and down by the eccentricity of the rotation center axis with respect to the drive axis. For this reason, the up-and-down movement of the first peripheral surface becomes diversified, and a tighter top surface can be formed. When the trimming portion rotates, the second peripheral surface moves toward and away from the one side surface of the old kite due to the eccentricity of the rotation center axis with respect to the drive axis. For this reason, it is possible to form one side surface with tightening, and as a result, it is possible to form a new bag having a top surface and one side surface with tightening.

  Furthermore, the present invention is characterized in that the pressing operation of the upper surface of the old iron by the first circumferential surface and the pressing operation of one side surface of the old iron by the second circumferential surface are performed in synchronization with the rotational movement of the trimming portion. .

  According to the present invention, the pressing operation to the upper surface of the old hook by the first circumferential surface and the pressing operation to the one side surface of the old hammer by the second circumferential surface are synchronized with the rotational movement of the trimming portion. The upper surface and one side surface of the old iron are pressed together at the same time, and as a result, the new iron can be formed with a uniform and surely tightened degree of the entire new iron.

  In the present invention, the first peripheral surface is formed so that the angular difference in the extending direction of each portion of the first peripheral surface formed on the opposite sides with the rotation center axis as the center is maximized. It is characterized by that.

  According to the present invention, the first circumferential surface is formed so that the angular difference in the extending direction of each part is maximized, so that the first circumferential surface rotates while the first shaping portion rotates halfway. While pressing the upper surface, and further rotating halfway, the first circumferential surface releases the pressing operation while being separated from the upper surface of the collar. That is, the pressing operation by the first peripheral surface becomes intermittent. For this reason, it is possible to form the tightened saddle upper surface more reliably by loosening the tightly tightened saddle upper surface and then pressing the first peripheral surface again.

  Further, the present invention is characterized in that the second peripheral surface of the lower rotating body portion has a polyhedral shape formed by arranging a plurality of surfaces in the circumferential direction.

  According to the present invention, the second peripheral surface is formed into a polyhedral shape formed by arranging a plurality of surfaces in the circumferential direction. The direction of the surface with respect to one side surface of the surface changes, and the surface itself presses the one side surface. For this reason, when the trimming part makes one rotation, a pressing operation is continuously performed by a plurality of surfaces, and a new punch having one side surface that is securely tightened together with the pressing operation of the entire lower rotating body part can be formed. it can.

  Further, the present invention is characterized in that a step portion is formed between adjacent surfaces of the plurality of surfaces.

  According to the present invention, by forming the step portion between the adjacent surfaces, it is possible to form a height difference between the adjacent surfaces. For this reason, when the trimming portion rotates, after one side surface is pressed by one side surface of the adjacent surfaces, the pressing operation is released by the stepped portion, and one side surface is pressed by the other side surface. That is, a pressing operation for pressing one side surface by an adjacent surface and a releasing operation for canceling this operation are continuously performed. For this reason, the pressing operation and the releasing operation are continuously repeated by the plurality of surfaces constituting the second peripheral surface by the rotation of the trimming portion, and a new punch having one side surface that is securely tightened can be formed.

  Further, according to the present invention, the pretreatment unit includes a rotation drive shaft that is inclined and extends in the vertical direction and is rotatably supported, and a plurality of tilling claws radially attached to the rotation drive shaft. The first tilling claw is attached to the top of the rotary drive shaft and cuts the top surface of the old tack, the second tilling claw is attached to the middle portion of the rotary drive shaft and cuts one side of the old tack, and rotates. It has the 3rd tilling nail which is attached to the lower part of a drive shaft, and cultivates the upper part of the field adjacent to an old tack.

By having a third tilling claw that cultivates the upper part of the field adjacent to, when the pretreatment section rotates, the top surface of the old ridge is cut in addition to one side of the old ridge by three types of cultivating claws. The upper part of the field adjacent to the old culvert is cultivated, and these soils are piled up in the crushed old culvert. As a result, even if the padding work is performed when the field or the old paddy is in a dry state, the moist soil under the surface of the field is cultivated by the third tilling nail and is piled up on the old paddle. It is possible to apply the soil containing slag to the old paddle, and to form a tight paddle without being affected by the dry state of the paddle. In addition, since the top surface of the cocoon can be cut by one pre-processing unit, a dedicated processing unit for cutting the top surface of the cocoon is not required, and the entire coating machine can be downsized.

  According to the scissor coating machine according to the present invention, the trimming unit is rotatable about the rotation center axis extending in the vertical direction as the rotation center, and the upper rotating body having the first circumferential surface capable of trimming the upper surface of the old basket. And a lower rotating body portion disposed below the upper rotating body portion and having a second circumferential surface capable of adjusting one side surface of the old hammer, and the first circumferential surface of the upper rotating body portion is The direction extending in the radial direction changes according to the rotation angle of the adjusting unit, the rotation center axis of the adjusting unit is eccentric with respect to the driving axis of the adjusting unit, and the preprocessing unit is inclined.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a glazing machine according to the present invention will be described below with reference to FIGS. For convenience of explanation, the directions of arrows shown in FIG. 1 (plan view) will be described below as the front-rear direction and the left-right direction.

  As shown in FIGS. 1 and 2 (rear view), the wrinkle coater 1 is mounted on the rear portion of the traveling machine body 90 and is supported on the mounting part 10 so as to be rotatable in the left-right direction. 90, a support frame 20 that extends in the right direction, and a working unit 30 that is provided at the front end of the support frame 20 and that performs a wiping operation using power transmitted from the traveling machine body 90.

  The mounting portion 10 includes a connecting frame 11 and a hitch frame 13 attached to the rear side. A three-point link connection mechanism including a top link and a lower link is provided at the rear portion of the traveling machine body 90. By connecting the connection frame 11 to the three-point link connection mechanism of the traveling machine body 90, the coater 1 is connected to the traveling machine body. 90. An input shaft is provided at the lower center of the hitch frame 13 in the left-right direction, and this input shaft is adapted to transmit power from the PTO shaft of the traveling machine body 90 via the transmission shaft.

  The support frame 20 includes a main body frame portion 21 and a telescopic frame portion 23 pivotally supported at the right end portion of the main body frame portion 21. The telescopic frame portion 23 is configured to have a plurality of frame members nested therein, and is capable of telescopic movement. Each frame member is formed with a plurality of holes extending in the vertical direction with a predetermined interval in the extending direction of the telescopic frame portion 23, and the holes of the inner frame member and the holes of the outer frame member are vertically aligned. When the lock pin is inserted into these holes in the state of being communicated, the telescopic frame portion 23 can be locked in a desired length. For this reason, the offset position of the working unit 30 can be adjusted by extending and retracting the telescopic frame unit 23. The telescopic frame portion 23 is movable between the side of the traveling machine body 90 and the rear side thereof, with the rotation fulcrum O with the main body frame portion 21 as the rotation center. The support frame 20 is provided with a lock mechanism that locks the rotation of the telescopic frame portion 23 at a position where the telescopic frame portion 23 extends to the side of the traveling aircraft body 90 and a position where it extends to the rear of the traveling aircraft body 90. ing.

  At the left end of the support frame 20, a gauge wheel 25, which has a disk shape toward the rear and also serves as a coulter, is provided so that the vertical position can be adjusted. The vertical position of the working part 30 is adjusted by the gauge wheel 25 to adjust the height of the new punch Us to be molded and to stabilize the trimming work.

  The working unit 30 is provided with a pre-processing unit 31 and a trimming unit 51 from the front side. First, the preprocessing unit 31 will be described. As shown in FIG. 3 (rear view), the preprocessing unit 31 is attached to the lower end of the telescopic frame unit 23 and is rotatably supported on the lower end side of the preprocessing transmission frame 32 extending obliquely downward. The shaft 33 includes a plurality of tilling claws 35 attached radially to the rotation drive shaft 33. The rotary drive shaft 33 extends in the vertical direction while being inclined so that the right end portion is positioned above the left end portion. In addition, when the working unit 30 is installed at the working position Ps, the rotation drive shaft 33 has a right end positioned above the upper surface of the ridge U and a left end positioned above the farm field F adjacent to the ridge U. It has the length which is located in. The rotation drive shaft 33 is arranged so as to be orthogonal to the left-right direction or obliquely extend with respect to the direction in which the flange U extends in a plan view when the working unit 30 is installed at the work position Ps. May be.

  The tilling claw 35 attached to the rotary drive shaft 33 is attached to the upper part of the rotary drive shaft 33 and cuts the upper surface of the old tack Uk, and attached to the middle portion of the rotary drive shaft 33 to the old tack. There are three types: a second tilling claw 37 that cuts the inner surface of Uk, and a third tilling claw 38 that is attached to the lower part of the rotary drive shaft 33 and cultivates the upper part of the field F adjacent to the old tack Uk. The third tillage claw 38 has a length capable of tilling the lower part of the top soil of the field F. For this reason, when the rotary drive shaft 33 rotates, the upper surface of the old rod Uk is cut apart by the three types of tilling claws 36, 37, and 38 in addition to the inner surface of the old rod Uk, and the field F adjacent to the old rod Uk. The upper part of the soil is cultivated, and the soil is piled up on the old ridge Uk where these soils have been cut. As a result, even when the surface of the field F and the old paddle Uk are dry, the wet soil below the surface of the field F is cultivated by the third tillage nail 38 and the old paddle Uk is filled. Therefore, moisture can be supplied to the old ridge Uk, and a new ridge with good tightness can be formed.

  As shown in FIGS. 1, 2, and 4, the trimming unit 51 is rotatably supported by the tip of a trimming transmission frame 52 that extends rearward from the lower end of the telescopic frame 23. The trimming portion 51 is attached to the old end of the trimming transmission frame 52 via a drive shaft 52a that is rotatably supported and extends obliquely in the vertical direction, and a mounting boss portion 60 formed on the drive shaft 52a. An upper rotating body portion 54 having a first circumferential surface 55 capable of trimming the upper surface of the kite Uk, and a second circumferential surface disposed below the upper rotating body portion 54 and capable of trimming the inner side surface of the old kite Uk. And a lower rotating body 57 having 58.

  The drive shaft 52a is connected to a pinion gear (not shown) that is built in the straightening transmission frame 52 and is rotationally driven by the power transmitted from the power transmission mechanism in the straightening transmission frame 52. The rotation center axis 53 of the trimming part 51 is fixed to the drive axis 56 of the drive shaft 52a by attaching the trimming part 51 to the mounting boss part 60 with a tapered seat plate 61 interposed therebetween. Therefore, the drive shaft 52a is connected to the drive shaft 52a. For this reason, when the drive shaft 52a rotates, the rotation center axis 53 rotates while swinging.

  The lower rotating body 57 has a cylindrical shape, and the rotation center axis thereof is disposed coaxially with the rotation center axis 53 of the trimming unit 51. The second peripheral surface 58 gradually expands as it moves upward in the axial direction so that the inner surface of the newly-formed new iron Us is inclined at a predetermined inclination angle. For this reason, when the drive shaft 52a rotates, the second peripheral surface 58 moves closer to and away from the inner surface of the old kite Uk due to the swing of the rotation center axis 53, thereby moving the inner surface of the old kite Uk. It is possible to form a tightened inner surface by pressing. In addition, the surface of the 2nd surrounding surface 58 is formed in the continuous planar shape extended curvedly.

  In addition, the 2nd surrounding surface 58 may be comprised by the polyhedron shape which arrange | positions a some surface in the circumferential direction. In this case, a plurality of surfaces are arranged so that a stepped portion is formed between adjacent surfaces. The step portion is formed on the downstream side in the rotational direction of the trimming portion 51. Thus, by forming the second peripheral surface 58 into a polyhedron shape and forming a stepped portion between adjacent surfaces, when the trimming portion 51 rotates, the inside of the old basket Uk depends on the rotation angle of the trimming portion 51. The orientation of the surface with respect to the side surface changes, and the inner surface can be pressed by the surface itself. As a result, when the adjusting unit 51 makes one rotation, a plurality of surfaces continuously press the inner surface. . For this reason, it is possible to form a new bag having an inner surface that is securely tightened in combination with the pressing operation of the entire lower rotating body.

  The upper rotator 54 is connected to the upper part of the lower rotator 57 in a fixed state. For this reason, when the drive shaft 52 a rotates, the upper rotating body portion 54 rotates together with the lower rotating body portion 57. The first circumferential surface 55 of the upper rotating body portion 54 gradually expands as it moves upward in the axial direction so that the upper surface of the newly formed new basket Us extends substantially in the horizontal direction. Further, the direction of the first peripheral surface 55 extending radially outward with respect to the rotation center axis 53 changes according to the rotation angle of the trimming portion 51. More specifically, the first peripheral surface 55 is shaped so that the angular difference between the extending directions of the respective portions of the first peripheral surface 55 extending on opposite sides with the rotation center axis 53 as the center is maximized. ing. That is, when the direction of the first peripheral surface 55 extending to the one side with respect to the rotation center axis 53 as the center and the second peripheral surface 58 extending is “a °”, the rotation center axis 53 is set to the center and extends to the other side. The extending direction of the first peripheral surface 55 is formed to be “a ° + α”, and the first peripheral surface 55 therebetween has an angle in the extending direction as approaching the surface having the extending angle of “a ° + α”. It is shaped to gradually increase.

  As a result, when the drive shaft 52a rotates, the first peripheral surface 55 installed on the upper surface of the old kite Uk moves up and down while rotating. That is, the first peripheral surface 55 presses the upper surface of the heel while rotating while the trimming portion 51 rotates halfway, and the first peripheral surface 55 performs a pressing operation while gradually separating from the upper surface of the heel while further rotating halfway. The first peripheral surface 55 is released and intermittently performs the heel pressing operation. For this reason, since the collar upper surface once tightened loosens and is again pressed by the 1st surrounding surface 55, the collar upper surface tightened more reliably can be shape | molded.

  Further, the first peripheral surface 55 is shaped so as to be synchronized with the pressing operation of the inner surface of the old kite Uk described above by the second peripheral surface 58. That is, when the inner surface of the old heel Uk is pressed by the second peripheral surface 58, the upper surface of the old heel Uk is pressed by the first peripheral surface 55. For this reason, the upper surface and the inner side surface of the old ridge Uk are pressed together at the same time, and as a result, a new ridge having a uniform and firm tightening degree can be formed.

  The power transmission mechanism 70 that transmits power to the preprocessing unit 31 and the trimming unit 51 is disposed at a lower position of the support frame 20, is connected to the input shaft at one end side, extends along the support frame 20, and the other end. 3 has a universal joint 72 connected to a gear box 71 disposed on the lower side of the front end of the support frame 20, and the pretreatment transmission frame 32 and the adjustment transmission frame 52 shown in FIG. Do it. The gear box 71 is configured to be able to transmit the power transmitted from the universal joint 72 to power transmission means built in the pre-processing transmission frame 32 and the rectifying transmission frame 52. For this reason, the motive power transmitted from the traveling machine body 90 to the input shaft is transmitted to the preprocessing unit 31 and the trimming unit 51 via the universal joint 72, the gear box 71, and the power transmission means.

  Next, the operation of the hull coater 1 in the case of hulling one side of the field F with the hull coater 1 according to the present invention will be described with reference to FIGS. 1 and 5. As shown in FIG. 1, first, the traveling machine body 90 is installed at a position along one side Fa of the farm field F. When the telescopic frame portion 23 is rotated to the rear side of the traveling machine body 90, the telescopic frame portion 23 is rotated to the heel side, and the telescopic frame portion 23 is expanded and contracted with respect to the main body frame portion 21 to offset the working unit 30. The work unit 30 is moved to the work position Ps. Then, the telescopic frame portion 23 is fixed to the main body frame portion 21 with a lock pin. Then, the traveling machine body 90 is moved forward, and the power from the traveling machine body 90 is transmitted to the working unit 30 to rotate the preprocessing unit 31 and the rectifying unit 51. As a result, the plurality of tilling claws 35 of the pretreatment unit 31 cuts the upper part of the old tack Uk, cuts the inner surface of the old tack Uk, and plows the upper part of the field F adjacent to the old tack Uk.

  Then, the cut and cultivated soil is piled up on the old paddle Uk. Then, as shown in FIG. 5A, the first circumferential surface 55 of the upper rotating body portion 54 of the trimming portion 51 presses and compresses the upper surface of the old rod Uk by an intermittent pressing operation, and the lower rotating body portion 57 The second peripheral surface 58 presses and solidifies the inner surface of the old bag Uk by a pressing operation. At this time, since the pressing operations of the first peripheral surface 55 and the second peripheral surface 58 are synchronized, as shown in FIG. Can be molded.

  Further, even when the surface of the field F and the straw are in a dry state, the third tillage claw 38 of the pretreatment unit 31 shown in FIG. 3 tills the wet soil below the surface of the field F as described above. Since the paddle Uk is piled up, the newly formed new cup Us does not become brittle, and the new cup Us having good tightness can be formed.

  In the above-described embodiment, the example in which the first peripheral surface 55 of the upper rotating body portion 54 is formed as a curved surface that continuously extends has been described. However, a plurality of surfaces similar to the second peripheral surface 58 are illustrated. May be formed into a polyhedron shape, and a stepped portion may be formed between the surfaces.
