Description

  The present invention relates to a soil cultivator that is arranged in a plurality of rows behind a soil cultivating machine such as a cultivator, and digs up soil in a field by traction and piles up a ridge.

The cultivator has a cultivating plate surface extending diagonally upward and rearward on the left and right of the central ridge line portion of the culturing plate main body attached to the shank, and an extension auxiliary wing plate is coupled to the tip of the left and right cultivating plate surface.
This kind of cultivator has different cultivating height and cultivating width depending on the type of work, the degree of growth of the crop, the preference of the cultivator, etc., and its adjustment means are necessary.

In the conventional earthenware, the earthing plate main body is connected to the front end side of the shank so as not to be separated, so that the mounting position with respect to the shank and the rear upward angle are constant. For this reason, accessory parts are used as means for adjusting the cultivation height (for example, Japanese Utility Model Publication No. 5-1202), or the tip of the auxiliary wing plate can be vertically adjusted (for example, Japanese Patent No. 3780234). Gazette). However, the former has a problem that the number of parts is large and the cost is high, and the latter cannot secure a sufficient adjustment range.
In addition, in order to reduce the height of the soil plate main body itself, the mounting height of the shank itself must be changed. Above all, the conventional soil cultivator has a fixed mounting posture of the soil plate main body to the shank. There were restrictions on adjusting the cultivation height in various ways.

  Further, in Japanese Patent No. 3780234, a soil width adjusting member having a horizontally long hole formed in the axial direction can be connected to the left and right ends of the soil plate main body, and the soil width adjusting member can be expanded and contracted horizontally through the horizontally long hole. Although the earthenware container thus constructed is disclosed, the earthing width adjusting member can only be expanded and contracted linearly along the laterally long hole, and cannot adjust the longitudinal angle with respect to the earthing plate main body. In order to enable front-rear angle adjustment, it is necessary to connect a separate rotating member to the tip of the soil width adjusting member so as to be able to rotate. It will be troublesome.

  On the other hand, the conventional cultivator is difficult to increase or decrease the amount of soil because the cutting edge is inseparably connected to the soil plate by welding or caulking. There was also a problem that the corresponding amount of cultivation soil was not supplied.

No. 5-1202 Japanese Patent No. 3780234

  Therefore, the first object of the present invention is to adjust the height of the soil by simple replacement work to the shank, and at the same time achieve the expansion and contraction adjustment and angle adjustment of the extension auxiliary wing plate to the soil plate main body. Is to provide a vessel.

  The second object of the present invention is to provide a soil cultivator capable of adjusting the amount of soil culturing with a simple replacement work.

  Furthermore, the third object of the present invention is to provide the above-mentioned soil cultivator in which the left and right extension auxiliary blades connected to the soil slab main body are exchanged so that the soil simmering edge can be reversed in the reverse direction.

  In order to achieve the above first object, the earthenware container of the present invention includes a shank having an upper portion attached to a soil working machine, a soil plate main body attached to the tip of the shank, and the soil plate main body. A cultivator towing cultivator with extended auxiliary blades connected to both left and right ends, wherein the shank is bent in a concave shape with the tip side downward in the traction direction, and the cultivating plate main body follows the curved surface The curved portion of the shank and the central ridge line portion of the soil plate main body that is in contact with the curved portion are formed on the contact surface of one member. In addition to having an attachment portion, the contact surface of the other member has a plurality of upper and lower attachment holes that are selectively coupled to the attachment portion of the one member, and the soil is cultivated by selectively coupling these attachment holes. Vertical angle of the plate body with respect to the curved part of the shank And a plurality of vertically elongated holes are formed in each of the left and right soil plate surfaces of the central ridge line portion, and the left and right extension auxiliary blades have a horizontally elongated hole extending in the axial direction. In addition, it is possible to change the extension length and angle of the extension auxiliary blade plate with respect to the left and right ends of the culture plate surface by coupling the horizontally long hole to any corresponding position of the vertical hole of the culture plate surface. To do.

In order to achieve the second object, an excavation blade having a different shape or the same shape can be detachably attached to the tip of the earthenware blade and the earthing plate main body of the present invention.

In order to achieve the third object, the earthenware container of the present invention can be reversely coupled by forming the axial edge of the auxiliary auxiliary blade plate in an asymmetric shape with respect to the central axis and switching the left and right extended auxiliary blade plates. It is characterized by doing so.

In this case, preferably, the extension auxiliary vane plate has a configuration in which an inner flexible blade and an outer support blade whose tip side is separated from the outer side of the inner flexible blade are overlapped, and further, the inner flexible blade The outer support blades may be extended and contracted independently through the mutual long holes.

  The front end of the shank is bent in a concave shape downward in the pulling direction to form a curved portion having a length that allows the soil plate main body to be vertically displaced along the curved surface, and is coupled to the curved portion of the shank. The upper and lower surfaces are selectively connected to the contact surface of the one member on the contact surface of the other member while forming the attachment portion on the contact surface of any one member of the central ridge line portion of the main body plate Since a plurality of mounting holes are formed, by selecting and replacing these mounting holes, the posture (vertical angle in the rearward direction) of the culture plate main body with respect to the curved portion of the shank is changed, and height control of the culture soil is possible. For example, when coupled through the lower mounting hole, the excavating blade at the tip of the earthenware vessel turns further downward, and the rear auxiliary vane plate turns further upward. Therefore, since the soil increased by the deep excavation of the excavating blade is supplied to the auxiliary blade plate displaced upward, the soil becomes high. Conversely, when coupled through the upper mounting hole, the orientation of the earthenware vessel, that is, the angle becomes gentle, and this reduces the amount of soiling by the excavating blade, so the auxiliary blades also become lower, so the lower soiling become. As described above, the above-mentioned action and effect of the present invention in which the soil amount and the soil height are harmonized by the angular displacement of the soil cultivator with respect to the shank cannot be obtained from a mechanism that simply translates the soil cultivator up and down.

  Further, the earthenware container of the present invention is formed with a plurality of vertically long holes in each of the left and right earthing plate surfaces of the central ridge line part and with a horizontally long hole in the axial direction of the extension auxiliary blades. The extension length and angle of the extension auxiliary wing plate with respect to the tip of the culture plate surface are changed by connecting the horizontal holes to any corresponding positions of the multiple vertical holes on the culture plate surface while rotating the plate to the culture plate surface. can do.

  When the excavating blade is worn, it can be replaced with a new excavating blade without removing the main body. Further, by exchanging with excavation blades having different excavation widths, the amount of soil can be adjusted as necessary.

  Agricultural soil in which the direction of the extension auxiliary wing plate is changed back and forth by forming the axial edge of the extension auxiliary wing plate asymmetric with respect to the central axis and switching the left and right extension auxiliary wing plates so that they can be connected in reverse. In addition, the service life is improved by inversion.

  Since the inner flexible blades of the extension auxiliary blades can be expanded and contracted independently of the outer support blades, the soil pressure at the top of the ridge or interference with crops can be adjusted in various ways.
