The idea does not specify the material, shape, structure, arrangement, etc. of the component parts as follows. The technical idea of the present invention can be variously modified within the technical scope defined by the claims described in the claims of the utility model registration.

 A streak-covering work machine showing an embodiment of the present invention is installed at the rear of a self-propelled vehicle such as a tractor.

(First embodiment)
The streak-covering mold working machine according to the first embodiment of the present invention mainly comprises a machine frame and a molded plate. As shown in FIGS. 1 and 2, the machine frame includes a first horizontal frame 10, a second horizontal frame 40, an inside bar 11, an outside bar 12, a center bar 13, a first vertical frame 14, and a second vertical frame 15. Etc.

  The second horizontal frame 40 is installed horizontally on the rear part of the tractor or the like via the connecting part 5. Further, the first horizontal frame 10 is disposed in parallel below the second horizontal frame using the connecting member 43. In FIGS. 1 to 3, the first horizontal frame 10 and the second horizontal frame 40 are connected by the parallel link mechanism 4, but in the first embodiment, the link mechanism 4 is a component. It is not. The 1st horizontal frame 10 is formed in the length about the width | variety of 1 rib surface. The material of the first horizontal frame is light and rigid, and a metal square pipe is suitable from the viewpoint of easy installation of the second vertical frame and the like described later. The second horizontal frame 40 is formed with the same material and length as the first horizontal frame. The reason why the first horizontal frame 10 is arranged below the second horizontal frame is that the connection point of the self-propelled vehicle such as a tractor is at a higher position than the surface. As shown in FIG. 3A, by providing the first horizontal frame 10, the outside bar 12, the center bar 13, and the like that support the molding plate 20 that performs the molding work of the streaks are kept parallel to the ridge surface. It becomes possible.

  As shown in FIG. 1, outside support portions 17 each having an L-shaped angle are provided on both ends of the first horizontal frame 10. In addition, two inside support portions 16 each having an L-shaped angle are provided in the central portion of the first horizontal frame 10 in a bilaterally symmetrical manner.

  In the striped soil covering working machine of the present invention, two molded plates 20 are arranged in a substantially C shape behind the first horizontal frame 10. One molded plate 20 is a horizontally long plate-like body provided with a bar mounting portion 20a that is L-shaped in a side view so that a first vertical frame, which will be described later, can be installed on the upper side. Since the ridge surface is often inclined slightly from the short central portion to the left and right ridge grooves, the molded plates are formed and arranged one by one on the left and on the right instead of one. By comprising in this way, it becomes possible to make the shaping | molding board 20 follow along a collar surface appropriately.

  As shown in FIG. 5, the molding plate 20 is disposed obliquely on the left and right rear. Although illustration is abbreviate | omitted about a self-propelled vehicle, a self-propelled vehicle straddles a fence and a wheel advances in the left and right ridges of a fence. The molding board 20 sends the scattered soil on the ridge surface left and right from the center, the cover soil is formed in a streak shape from the notch hole 200 portion, and the excess soil is pushed out into the ridge groove. The inner ends of the respective molded plates 20 are configured to overlap in the forward and backward directions. By arranging so as to overlap, it is possible to appropriately cover the soil along the bulb planting hole without the excess soil on the ridge surface remaining in the center portion of the short surface of the ridge surface. For the same reason, the molded plate 20 is arranged in a substantially C shape instead of a V shape in the traveling direction.

  The material of the molding plate 20 is suitably made of synthetic resin because it is necessary to cover the soil without damaging the multi-sheet, but any other material can be used as long as it can level the soil released on the upper surface of the multi-sheet. The material is not disturbed. As shown in FIG. 5, the long side of the molded plate 20 is formed so as to be approximately half the length of the ridge width in a state where the long side is disposed obliquely toward the rear. A plurality of cutout holes 200 are formed on the lower side. In the present embodiment, the bar mounting portion 20a is configured to be bolted with an L-shaped angle which is a separate member, but may be integrally formed of a synthetic resin material.

  As shown in FIGS. 1 to 5, a plurality of notch holes 200 are provided on the lower side of the molding plate 20. Since it is customary to plant garlic in four rows per line, these drawings show two notch holes 200 for one molded plate 20, but this number is limited. Not. Further, the shape of the cutout hole 200 is drawn so that the cutout portion is substantially rectangular, but other shapes such as a triangle or a dome shape may be used. However, as shown in FIG. 4, the lower side of the molding plate 20 needs to take a corner at a location in contact with the multi-sheet S. This is because if the corners are left, the corners may pierce the multi-sheet S and break.

  As shown in FIGS. 1 and 2, a first vertical frame 14 protrudes perpendicularly to the long side of the molded plate 20 at the center of the bar mounting portion. Further, a first plate support portion 18 for connecting an inside bar 11 described later and a second plate support portion 19 for connecting the outside bar 12 are fixed to the left and right sides of the bar mounting portion. An L-shaped angle that is lightweight and strong can be used for the first plate support portion 18 and the second plate support portion 19.

  The inside bar 11 is connected to the first plate support portion 18 and the inside support portion 16 of the first horizontal frame provided on the two molded plates 20 arranged in a substantially C shape so as to swing up and down. . When a flat bar is used as a member of the inside bar 11, the connecting portion is in a state in which a bolt and a nut are loosely fitted. This connecting portion may be riveted as long as it is loosely fitted, or depending on the shape of the inside bar 11, the connecting portion may be formed of a ball joint. Similarly, an outside bar 12 is connected to the outside support part 17 and the second plate support part 19 so as to be swingable up and down, and a center bar is provided above each of the first vertical frame and the second vertical frame. 13 is connected to be swingable up and down.

  The attachment positions of the inside support portion 16 and the outside support portion 17 are symmetrical, but the left and right inside support portions 16 and the outside support portion 17 are formed to have different lengths. This is because the inner ends of the left and right molded plates 20 overlap each other as described above by changing the left and right lengths. As described above, since the lengths of the left and right inside support portions 16 and the outside support portion 17 are different, the length of the center bar 13 is also different on the left and right. However, it is desirable that the lengths of the inside bar 11 and the outside bar 12 are equal. This is to maintain the balance of twisting generated in the machine frame due to the unevenness on the surface.

  As shown in FIG. 3, when the inside bar 11, the outside bar 12, and the center bar 13 are connected so as to be swingable up and down, the molding plate 20 can move up and down with respect to the unevenness in the longitudinal direction of the flange surface. it can. FIG. 3 (B) shows the inside bar 11 and the outside so that the molding plate 20 is pushed upward when the scattered soil in the place where the ridge surface behind the traveling direction is high is leveled, and follows this movement. The bar 12 and the center bar 13 are also shown rising upward. FIG. 3C shows the movement when the heel surface behind the traveling direction is low.

  The molded plate 20 has a three-point support structure in which the left and right two points are supported by the inside bar 11 and the outside bar 12 and the center is supported by the center bar 13 at a high position. By adopting a three-point support structure in which each connection point is loosely fitted, the left and right molded plates 20 level the scattered soil along the ridge surface even if there are irregularities in the short direction of the ridge surface. I can do it.

As a material of the upper arm 41 and the lower arm 42, a metal L-shaped angle that is lightweight while having strength is suitable. The connecting member 43 includes a pipe and a round bar 43a passing through the pipe.

  As shown in FIGS. 1 and 2, the roller 30 has a cylindrical shape and is rotatably connected to the roller support bar 31 so as to open outwardly downward. The roller support bar 31 is disposed on the left and right ends of the first horizontal frame 10 via a roller adjustment mechanism 32. The sliding roller adjusting mechanism 32 can adjust the position of the roller to the width of the ridge and the height of the ridge.

  With the configuration as described above, the roller 30 can rotate along the left and right side surfaces of the single ridge, and the machine frame can follow the self-propelled vehicle, so that the molded plate 20 can be maintained at an appropriate position. .

(Modification 1 of the first or second embodiment)
The first modification of the first or second embodiment of the present invention includes a protection auxiliary tool 21 on the lower side of the molded plate 20 other than the cutout hole 200.

  As shown in FIG. 1, the protection assisting tool 21 is arranged on the lower side between the cutout holes 200 of the molding plate 20 so as to extend rearward in a direction perpendicular to the molding plate 20. The protective auxiliary tool 21 is made of a synthetic resin and is formed into a trapezoidal plate-like body.

  By disposing the protective auxiliary tool 21, the area in contact with the multi-sheet increases, the sink of the molded plate 20 into the multi-sheet decreases, and the effect of preventing damage to the multi-sheet is further enhanced. Although illustration is omitted, as a protection auxiliary tool, a cylindrical roller type may be used instead of a plate-like body. Moreover, it is good also as what arrange | positions a brush etc. in lower sides other than the notch hole 200 of the shaping | molding board 20 as a protection auxiliary tool.
