  In the conventional configuration, a smooth and pressed ridge is formed in a normal soil field, but in the case of strong clay, the soil adheres to the surface of the divided piece and the surface of the ridge does not finish smoothly. Further, if the step is increased on the divided disk, the adhesion of soil can be reduced, but there is a problem that the range of the finishing condition is narrowed.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to review a structure of a cocoon forming apparatus in a cocoon forming machine and provide a cocoon forming machine that can continue a glazing operation smoothly even in a specific area of strong clay or soft ground.

  In order to solve the above-mentioned problems, a mounting portion for mounting on a traveling vehicle, a banking device having a crushing claw for crushing an old slag, an upper surface forming body and a side surface forming an upper surface of the crushed old slag A crust forming device comprising a side surface forming body to be formed, wherein the embankment device and the wrinkle forming device are rotationally driven wrinkle forming machines, wherein the side surface forming body has a large diameter outward from one end of the upper surface forming body The surface is composed of a plurality of continuous pieces that are radially divided and the edges of the pieces are overlapped on the upper part of the starting end of the piece adjacent to the rear in the rotational direction. The present invention provides a wrinkle forming machine characterized in that an elastic anti-adhesion material along the edge of the divided piece is further combined with the combined portion.

  The wrinkle forming machine according to claim 1 is characterized in that the divided pieces are made of stainless steel and the adhesion preventing material is made of a resin material.

  With the above configuration, even in strong clay and soft paddy fields, soil separation is improved and the finish of the surface of the paddy can be made clean without increasing the level difference between the divided pieces. Moreover, since the adhesion preventing material can be attached and detached as necessary at the combination part, the versatility of the crease forming machine has been increased.

FIG. 4 is a plan view showing the operation of the wrinkle forming apparatus.

  In FIG. 1, A denotes a ridge forming machine, which is composed of one mounting portion, two earthing devices, and three ridge forming devices. 1 includes a frame 11 that extends in the horizontal direction, a mounting mast 12 that protrudes forward from the frame 11 and that is mounted on a three-point link of a tractor that is a traveling vehicle (not shown), and a frame 11, a mission case 13 is arranged and configured at a substantially central portion.

  The transmission case 13 is provided with an input shaft 13a facing forward, and this input shaft 13a inputs the driving force of the tractor from the tractor PTO shaft through the universal joint 14 to the rod forming machine A, although not shown. is there.

  2 has a rotary 23 provided with a plurality of crushed claws 21 radially with respect to the axis of the claw shaft 22 and a rotary output shaft 24 for fixing one end of the rotary 23 for rotationally driving the rotary 23. The rotary drive case 25 is configured such that the rotary 23 is supported at one end of the frame 11 of the mounting portion 1 so as to be disposed forward with respect to the work progressing direction. A chain speed reducer 26 is provided inside the rotary drive case 25.

  3 is disposed behind the embankment device 2, and includes an upper surface forming body 31 that forms the upper surface of the old casket, a side surface forming body 32 that forms the side surface of the old casket, and the upper surface forming body 31. It comprises a heel-forming drive case 34 having a heel-forming output shaft 33 for rotationally driving the side surface forming body 32, and is supported together with the rotary drive case 25 at one end of the frame 11 of the mounting portion 1. A chain speed reducer 35 is provided inside the saddle formation drive case 34.

  The drive transmission will be described. Although not shown in the input shaft 13a projecting forward from the transmission case 13, when a driving force is input from the tractor PTO shaft through the universal joint 14, the transmission case 13 enters the interior of the transmission case 13. It is decelerated through the provided bevel gears 13b and 13c, and is transmitted to a drive shaft 13d that is rotatably provided inside a frame 11 constituted by a pipe body extending in the horizontal direction.

  A chain speed reducer 26 provided in the rotary drive case 25 includes a sprocket 26a fixed to the drive shaft 13d, a sprocket 26b fixed to the inner end of the rotary output shaft 24, and the sprockets 26a and 26b. By driving the drive shaft 13d composed of the chain 26c, the rotary 23 fixed to the rotary output shaft 24 is further decelerated and rotated by the chain reducer 26.

  The chain speed reducer 35 provided inside the hook forming drive case 34 is fixed to the sprocket 35a fixed to the drive shaft 13d and the inner end of the hook forming output shaft 33 protruding in the horizontal direction from the hook forming drive case 34. The sprocket 35b and the chain 35c wound around the sprockets 35a and 35b are driven by the drive shaft 13d, whereby the top surface forming body 31 and the side surface forming body 32 fixed to the flange forming output shaft 33 are connected to the chain speed reducer. 35 further decelerates and rotates.

  The side surface forming body 32 is configured by connecting and combining divided pieces 32c each having a conical shape and dividing the conical surface in the radial direction, and sandwiching an adhesion preventing material 32d in the combined portion.

  The wrinkle forming apparatus 3 will be described with reference to FIGS. The upper surface forming body 31 includes a boss 31a attached to the outer end portion of the ridge forming output shaft 33, and a cylindrical upper surface roller 31b fitted to the boss 31a. A plurality of spokes 32a that are radially provided to form a conical surface that gradually increases in diameter outward from the outer peripheral portion of the boss 31a that is one end of the body 31 toward the flange-forming output shaft 33 side, and of the spoke 32a A detachable ring 32b that connects the outer peripheral ends and a plurality of divided pieces 32c that are formed by concatenating the surface of the spoke 32a that is a conical surface radially and continuously are detachable.

  The divided piece 32c is provided with a combination portion by a bolt 36 such that the rear end edge thereof is overlapped with the front edge of the start end portion of the adjacent divided piece 32c with respect to the rotation direction f. Between the adjacent divided pieces 32c, the front edges of the anti-adhesive material 32d are sandwiched and penetrated and fixed through the bolts 36.

  The adhesion preventing material 32d is best an elastic plate material having appropriate elasticity or a resin material with good soil releasability. Since the other end of the resin material is a free end, even if the soil tries to adhere, it returns as appropriate and the soil does not adhere. The divided piece 32c is preferably made of stainless steel, and the anti-adhesion material 32d may be used in the case where the soil is soiled with strong clay or special soft soil. This machine is highly versatile and economical.

  FIG. 4 will be further described. F indicates the forward direction of the tractor, and f indicates the rotational direction of the side surface forming body having a conical surface. The rear end edge of the divided piece 32c is assembled by a bolt 36 so as to be superimposed above the start end portion of the adjacent divided piece 32c which is rearward with respect to the rotation direction. The adhesion preventing member 32d is sandwiched between the overlapping portions, and in this embodiment, the adjustment washer a is sandwiched below the adhesion preventing member 32d, and one end is set as a free end. When strong clay adheres to the adhesion preventing material 32d, the plate thickness formed by the rear end portion of the front and rear divided pieces 32c becomes a clearance angle and receives intermittent pressure, and the resin material of the adhesion preventing material 32d is elastic. Strong clay does not adhere because it vibrates depending on the nature and repeats the peeling action of the soil.
