Description

  The present invention generally relates to a device attached to a cultivator. More particularly, the present invention relates to a medium cultivating weeding apparatus for a cultivator that is attached to a cultivator and used to cut out weeds.

  In agricultural work, middle-plowing weeding works to improve soil air permeability, retain moisture, increase soil temperature, and activate soil microorganisms by stirring the topsoil of the field from the beginning to the middle of the crop. It is a control work and one of the important management work in the growing process of crops.

  Medium tillage and weeding operations are generally performed using cultivators. The cultivator is a work machine in which three to four middle tillers are mounted per frame on a frame. Conventionally, middle tillage weeding work is performed by attaching a willow blade to the tip of a middle tillage nail attached to a cultivator.

  However, since the willow blades are spaced apart, there is a problem that weeds located in that portion cannot be removed.

  The present invention has been devised in view of such a situation, and an object thereof is to provide a medium tillage weeding apparatus for cultivator that can accurately remove weeds located between adjacent middle tilling claws. Yes.

  The middle tillage weeding device for a cultivator according to claim 1 of the present invention has a shank extending horizontally in both directions or in one direction so as to be orthogonal to the center beam at a predetermined position of the center beam traveling along the center line of the furrow. A middle tilling nail attached to the tip and a grass cutter attached to the lower end of the middle tilling nail and for cutting out weeds located between the adjacent furrows are provided.

  The middle tillage weeding apparatus for cultivator according to claim 2 of the present application is the apparatus of claim 1, wherein the grass cutter is provided at a curved or straight blade portion and one end of the blade portion, An attachment portion that is bent so as to form a fixed angle with respect to the middle tillage nail by bolting the hole provided in the attachment portion to the hole provided at the lower end of the middle tillage nail. It is characterized by being attached.

  ADVANTAGE OF THE INVENTION According to this invention, in the middle plowing weeding work, weeds located between adjacent furrows can be cut out efficiently. Since the device of the present invention has a simple structure, the manufacturing cost is low and the possibility of failure is low, so that the maintenance cost can be kept low. In the apparatus of the present invention, a desired operation (for example, weed cutting at the base of a crop) can be easily performed by appropriately changing the attachment state (outward, inward, etc.) of the grass cutter.

  Next, with reference to the accompanying drawings, a medium tillage weeding apparatus for cultivator according to a preferred embodiment of the present invention will be described in detail. FIG. 1 is a rear perspective view showing a cultivator 10 provided with a cultivator middle tillage weeding apparatus according to a preferred embodiment of the present invention. A cultivator 10 shown in FIG. 1 is provided with a toolbar 14 having a mast 12 connected to a hydraulic three-point support device of a tractor (not shown) at the front.

  Three stringers 16 are bolted to the tool bar 14 via a clamp 18 at a predetermined interval. Each stringer 16 can be fixed at a desired position on the tool bar 14 by loosening a bolt and adjusting the position of the clamp 18.

  A center beam 20 is disposed below each stringer 16. One ends of swing links 22a and 22b are rotatably attached to the front end and the rear end of each stringer 16, respectively, and a U-shaped frame 22c provided at the front end and the center of each center beam 20 has a swing. The other ends of the moving links 22a and 22b are rotatably attached. Thus, a parallelogram link mechanism is formed by the vertical beam 16, the center beam 20, and the swing links 22a and 22b, and the center beam 20 can move up and down in parallel to the vertical beam 16. ing. A ruler wheel 26 is rotatably attached to the front end of the center beam 20 via a yoke 24. The configuration of the cultivator 10 described above is a known one and does not constitute the feature of the present invention.

  The medium tillage weeding apparatus for cultivator according to a preferred embodiment of the present invention includes shanks 28 extending horizontally in both directions so as to be orthogonal to the center beam 20 at predetermined positions of the center beam 20. A middle tilling nail 30 is attached to the tip.

  The cultivator's middle tillage weeding device also includes a grass cutter 32 attached to the lower end of the middle tillage nail 30. FIG. 3A is an enlarged perspective view showing the grass cutter 32. As shown in FIG. 3A, the grass cutter 32 has a curved blade portion 32a and a mounting portion 32b provided at one end of the blade portion 32a. A sharp blade edge 32a1 is provided at one edge of the blade portion 32a, and a hole 32b1 for bolting to the lower end of the middle tillage claw 30 is provided in the attachment portion 32b. Moreover, the attachment part 32b is bent so as to form a certain angle with respect to the blade part 32a.

  4A is a plan view showing a state in which the grass cutter 32 is attached to the middle tilling blade 30, and FIG. 4B is a side view taken along line 4b-4b in FIG. 4A. It is. The grass cutter 32 is attached to the middle tillage nail 30 by bolting the hole 32b1 of the attachment portion 32b to the hole 30a of the middle tillage nail 30.

  FIG. 3B is an enlarged perspective view showing another form of grass cutter 32 '. The grass cutter 32 ′ has substantially the same configuration as the grass cutter 32 except that the blade portion 32 ′ a is formed straight. That is, the grass cutter 32 'has a straight blade part 32'a and a mounting part 32'b provided at one end of the blade part 32'a. A sharp edge 32'a1 is provided at one edge of the blade portion 32'a, and a hole 32'b1 for bolting to the middle tiller 30 is provided in the attachment portion 32'b. Further, the attachment portion 32'b is bent so as to form a certain angle with respect to the blade portion 32'a.

  FIG. 5 is a plan view showing a middle tillage weeding apparatus for cultivator. In FIG. 5A, the grass cutter 32 is attached to the middle tiller 30 so that the tips of the adjacent grass cutters 32 are oriented toward each other. Alternatively, the grass cutter 32 may be attached to the middle tillage nail 30 so that the tips of the adjacent grass cutters 32 are oriented away from each other (see FIG. 5B).

  FIG. 6A shows an example in which the grass cutter 32 ′ is attached to the middle plow 30 so that the tips of the adjacent grass cutters 32 ′ are oriented toward each other, and FIG. 6B shows the adjacent grass cutter 32 ′. An example is shown in which the grass cutter 32 ′ is attached to the middle plow 30 so that the tips of the cutter 32 ′ are oriented away from each other.

  FIG. 7: is the top view which showed typically the state which is performing the middle tillage weeding work using the middle tillage weeding apparatus for cultivators of this invention. By running the cultivator 10 so that the center beam 20 moves along the center line of the intercostal space, weeds positioned between adjacent intercostal spaces can be cut by the grass cutters 32 and 32 '. Note that the grass cutters 32 and 32 'are placed on the middle tillage nail 30 so that the tips of the grass cutters 32 and 32' are located about 3 cm from the surface of the soil when the middle tillage nail 30 is located at about 5 cm in the soil. It is preferable to attach.

  The present invention is not limited to the above-described embodiments of the invention, and various modifications are possible within the scope of the invention described in the claims of the utility model registration, and these are also within the scope of the present invention. Needless to say, it is included.

  For example, in the embodiment described above, three center beams 20 are arranged on one toolbar 14, but the number of arranged center beams 20 is not limited to this. Further, the length, width, shape, and the like of the grass cutters 32, 32 'shown in the drawings are merely illustrative, and are not limited thereto. Further, in the above-described embodiment, the shank 28 (hence the middle tiller 30 and the grass cutters 32 and 32 ′) are provided in both directions of the center beam 20. A middle tiller 30 and grass cutters 32, 32 ') may be provided.
