  However, in the working machine described in Patent Document 1, the discharge curved surface is effective in the case of crushing only the soil, but in the case of soil containing grass etc., the grass is entangled with the entire member including the knife, There is a disadvantage that work efficiency deteriorates. Moreover, in the case of the working machines described in Patent Documents 2 and 3, there is a problem that the load on the subsoiler becomes extremely high because the subsoiler performs the crushed work prior to the rotor.

  In addition, there is a problem that the grass embedded in the soil by the rotor portion is dug up into the top soil by the subsoiler.

  This invention is made | formed in view of the said subject, and an example of the objective is to provide the subsoiler structure by which a pasture etc. are not dug up in topsoil by a subsoiler.

  In order to solve the above-described problems, the present invention is a sub-soiler mechanism that is used by being attached to a rear side of a rotary mechanism of a tilling work machine and crushes a cultivating layer formed by a rotor of the rotary mechanism, wherein the sub-soiler mechanism Is arranged at the lower end of the blade-like arm extending in the vertical direction, protrudes in the traveling direction of the vehicle to which the tilling work machine is attached, and scrapes the tiller layer as the vehicle progresses A grooving blade to be crushed and a rotating disk formed to be rotatable with respect to the blade-like arm.

  According to the subsoiler mechanism of the present invention, it is possible to provide a subsoiler structure in which grass and the like are not dug up in the topsoil.

It is a side view showing a tillage working machine provided with a subsoiler mechanism concerning the present invention. It is explanatory drawing of the subsoiler mechanism which concerns on this invention. It is the schematic which shows the relationship between a crushed soil layer, a tilling layer, a drain ditch, and the rotary tiller provided with the subsoiler mechanism which concerns on this invention.

  FIG. 1 is a side view showing a tillage working machine 1 provided with a subsoiler mechanism 6 according to the present invention.

  The tilling work machine 1 includes a rotor 2, a cover 3, a rotary mechanism 5 having a comb rake 4 and a sub soiler mechanism 6 having a sub soiler 10 and a rotating disk 13 (see also FIG. 3 for the following explanation). about).

  The subsoiler mechanism 6 is used by being attached to the rear side of the rotary mechanism 5 and crushes the tiller layer b formed by the rotor 2.

  The subsoiler mechanism 6 has a blade-like arm 11 extending in the vertical direction, and is disposed at the lower end of the blade-like arm 11 and protrudes in the traveling direction of the vehicle to which the tilling work machine 1 is attached. A groove cutting edge 12 that scrapes and crushes the layer b and a rotating disk 13 that is formed to be rotatable with respect to the blade-like arm 11 are provided.

  In addition, in the case of this embodiment, the rotor 2 is an aspect of an up cut rotor, However, It is not limited to this.

  Below, the function of the rotary mechanism 5 is demonstrated.

  When the vehicle equipped with the tillage work machine 1 moves forward, the rotor 2 of the rotary mechanism 5 is rotated in accordance with it, and the rotary claw 2a provided at the tip of the rotor 2 reaches a certain depth to crush the soil. It forms a two-layered soil that is fine and rough in the lower layer.

  The crushed crushed soil is sent to the upper portion of the rotor 2 as the rotor 2 rotates, and the grass mats and weeds contained in the crushed soil are embedded in the lower layer by the combi reiki 4 provided at the upper rear portion in the working direction. At this time, a cover 3 is provided on the front upper part in the work progressing direction so that the crushed soil sent upward from the rotor 2 does not scatter.

  After plowing with the rotor 2 as described above, the subsoiler 10 acts on the cultivating layer b.

  Therefore, since the subsoiler mechanism 6 is attached to the rear of the tilling shaft, the subsoiler 10 advances through the soil softened to some extent by the rotor 2.

  As a result, the load of horsepower applied to the subsoiler mechanism 6 is reduced.

Next, the subsoiler mechanism 6 will be described with reference to FIGS. 2a, 2b and 2c.
FIG. 2a is a top view of the subsoiler mechanism 6 according to the present invention. FIG. 2b is a side view of the subsoiler mechanism 6 according to the present invention. FIG. 2c is a front view of the subsoiler mechanism 6 according to the present invention as viewed from the front in the working direction.

  As described above, the subsoiler mechanism 6 includes the subsoiler 10 and the rotating disk 13 that is rotatably provided on the blade-like arm 11 of the subsoiler 10, and is provided behind the rotary mechanism 5 in the working direction.

  The subsoiler 10 has a substantially straight shape as a whole, and it is difficult to raise the soil mass to the upper layer.

  Further, the blade-like arm 11 of the subsoiler 10 is chamfered obliquely at the edge toward the working direction when the grooving blade 12 is grounded, that is, the edge portion closest to the scraped soil mass.

  For this reason, in the case of a subsoiler that is hard to stay in that part and is bent entirely or chamfered at the edge, crushed soil or pasture is entangled and the clot calls the clot and the work efficiency of the subsoiler Can be significantly reduced, but this can be avoided.

  The subsoiler 10 is deeper than the relatively soft cultivating layer b that the rotor 2 can reach, and the cutting edge provided at the tip of the subsoiler 10 reaches a layer having high hardness to crush the soil and form the drainage c.

  At that time, the tip of the groove cutting edge of the subsoiler reaches deeper than the position reached by the rotor 2. In particular, it is preferable that the tip of the groove cutting edge of the subsoiler reaches a depth of 100 mm from the position where the rotor 2 reaches. Further, by setting the subsoiler blade width to about 25 mm, it becomes possible to plant straightly even during transplantation work.

  The groove cutting edge 12 of the subsoiler 10 protrudes in the working direction. Therefore, the crushed soil crushed by the subsoiler 10 is kicked up simultaneously with the crushed and scattered upward.

  If it does so, it will be inevitable that the cultivation layer which is made of Kushireiki 4 and which consists of two layers embedded with grass etc. will be destroyed.

  Therefore, the rotating disk 13 having a rotating shaft coupled to the blade-like arm 11 of the subsoiler 10 is driven by the progress of the work machine, and rotates in a direction opposite to the direction in which the subsoiler 10 is scraped up.

  This action makes it possible to return the crushed soil, grass, and the like to the cultivating layer b again, so that the wrapping of grass is reduced and the soil does not come out on the soil surface, so the accuracy of the sowing operation is improved. . At this time, it is desirable that the tip blade of the subsoiler 10 does not protrude from the outer periphery of the rotating disk 13.

  The rotating disk 13 is provided close to the rotor 2 so that the outer peripheral circle 13b does not contact the rotating circular outer periphery 2b of the rotor 2. By bringing the rotary mechanism 5 and the subsoiler mechanism 6 as close as possible, a series of work efficiencies of the combi reiki 4, the subsoiler 10, and the rotating disk 13 can be optimized. Moreover, since the working location of the tillage work machine 1 and soil is close, the balance of the work work machine 1 itself as a work machine can be kept optimal.

  It is more appropriate to provide a scraper 7 between the rotary disk 13 and the blade-like arm 11 to prevent soil from adhering to the rotary disk 13.

  Further, the rotating disk 13 may be any shape that can rotate, and is not limited to a circular shape, and may be an arbitrary polygon.

  In addition, if the shear bolt 14 is used for coupling the subsoiler 10 and the blade-like arm 11, loosening due to vibration can be avoided as much as possible, and the tightening torque of the shear bolt 14 can be controlled in accordance with characteristics such as soil hardness. Convenient to do.

  Furthermore, with the above-described configuration, the sub-soiler 10 and the rotor 2 are always spaced apart from each other by a constant distance, so that there is an advantage that the shear bolt 14 is not easily broken.

  Next, how the function of the subsoiler mechanism 6 acts on the soil will be described.

  FIG. 3 is a schematic view showing the relationship between the crushed soil layer a, the tilling layer b of the rotary claw 2a, and the tilling work machine 1 provided with the subsoiler mechanism 6 according to the present invention.

  As described above, when the rotor 2 rotates, a two-layered cultivated soil is formed. That is, the rotor 2 performs crushed soil in this range with the tilled layer b from the crushed soil layer a that is the outermost layer to the depth reached by the tillage claws of the rotor 2. Then, the grass mat and weeds are embedded in the lower layer by the comb reiki 4 through the cover 3.

  The above is the function of the rotary mechanism 5, and the above-described work is sufficient for normal tilling work. However, if further soil improvement is required, the subsoiler mechanism 6 is attached and the soil is crushed deeper than the cultivating layer b to form the drainage c. At this time, the tire treading portion formed by the tire of the vehicle to which the tilling work machine 1 is attached can be crushed simultaneously.

  By doing so, it becomes possible to improve the drainage of the tillage layer, and it is possible to maintain an appropriate moisture range in the crop. Further, since the cultivating layer b is left at intervals, it is possible to prevent the fertilizer from coming off, and to stably perform the transplanting machine and the harvesting work.
