  An embodiment of an agricultural machine according to the present invention will be described with reference to the drawings.

  1 and 2, reference numeral 1 denotes an agricultural machine. The agricultural machine 1 is a towing type that is used by being connected to a tractor (not shown) that is a traveling vehicle. And the agricultural working machine 1 is a multi-row seeding machine that performs sowing work and the like while moving forward (in the direction of the arrow in the figure) by traveling of the tractor.

  The farm work machine 1 includes a machine body 3 having a three-point connecting portion 2 connected to a three-point link portion of a tractor (not shown).

  An input shaft 5 is rotatably provided on the bearing portion 4 of the body 3, and a PTO shaft of a tractor is connected to the input shaft 5 via a universal joint, a transmission shaft, and the like.

  On the front side of the machine body 3, there is provided rotary type tillage means 7 that receives power from the input shaft 5 side and performs tilling work while driving and rotating in a predetermined direction.

  Further, on the rear side of the machine body 3, groove forming means 8 disposed on the rear portion of the tillage means 7 and forming a grooved sowing groove b on the field surface portion a so as to open the tillage soil left and right, and Sowing means 9 for sowing the seed (waste, fertilizer, medicine, etc.) W in the sowing groove b formed by the groove forming means 8 and sowing means 9 disposed in the vicinity of the groove forming means 8 A soil covering means 10 for performing soil covering work on the seed W is provided. In addition, in the rear part of the groove forming means 8, a pressure-reducing wheel 11 that is a pressure-reducing means for performing pressure-reducing work on a portion of the field surface portion a where the seed W is sown is rotatably arranged. .

  Here, the tilling means 7 includes a left and right tilling shaft 15 that receives power from the input shaft 5 side and is driven to rotate in a predetermined direction about the rotation center axis X. The tilling shaft 15 includes a shaft portion 16 whose axial direction is aligned with the left-right direction, and a plurality of substantially plate-like flange portions 17 that are arranged in parallel in the axial direction at a distance from the shaft portion 16. .

  Of the plurality of flange portions 17, each flange portion 17 positioned in front of the groove forming means 8 is provided with a plurality of (for example, four) straight claws (usually four) that perform tilling work in front of the groove forming means 8. And a plurality of (for example, two) bent claws 19 that are bent in a substantially curved shape toward one side (for example, the left side) and perform a tilling operation in front of the soil covering means 10 are provided. It has been. That is, the straight claw 18 and the bent claw 19 are attached to the same flange portion 17.

  As shown in FIGS. 3 and 4, each straight claw 18 is substantially plate-shaped along the radial direction of the shaft portion 16 of the tillage shaft 15, that is, substantially straight in plan view. A proximal end portion is detachably attached to the flange portion 17, and a distal end portion of each straight claw 18 is a free end portion. Each bent claw 19 is substantially J-shaped in plan view, and the base end portion of each bent claw 19 is detachably attached to the flange portion 17, and the distal end portion of each bent claw 19 is a free end portion. ing. Note that the tilling depth of the bent claws 19 is shallower than the tilling depth of the straight claws 18.

  Further, each of the remaining flange portions 17 has a plurality of (for example, two) drainage groove forming claws 20 that form a concave drainage groove c in a portion between adjacent seeding grooves b in the field surface portion a. Is provided. Each drainage groove forming claw 20 is substantially U-shaped in plan view, and the base end portion of each drainage groove forming claw 20 is detachably attached to the flange portion 17, so that each drainage groove forming claw 20 The tip is a free end. Note that the tilling depth of the drainage groove forming claws 20 is deeper than the tilling depth of the straight claws 18.

  The groove forming means 8 is configured by, for example, a substantially circular rotating disk (disk) 22 that is arranged in a substantially V shape in plan view and forms a pair that rotates around a horizontal support shaft 21. Each rotating disk 22 is rotated by the force received from the field surface portion a in a grounded state.

  The seeding means 9 includes a hopper 24 for storing the seed W. A take-out roll (not shown) for taking out the seed W in the hopper 24 by a fixed amount is rotatably provided at the bottom of the hopper 24. ing. The take-out roll rotates upon receiving power from the drive wheel 25 side. In addition, the seed W to be taken out from the hopper 24 is guided to the space between the rotating disks 22 paired by a derivative 26 such as a guide tube, and falls into the seeding groove b.

  The soil covering means 10 is composed of, for example, a substantially disk-shaped rotating soil covering disk (covering disk) 29 that performs soil covering work while rotating around a horizontal support shaft 28 with a slight inclination with respect to the front-rear direction. Has been. Each of the soil covering rotating disks 29 is rotated by the force received from the field surface portion a in a grounded state, like the rotating disk 22 of the groove forming means 8.

  Next, the operation of the above embodiment will be described.

  When the farm work machine 1 is connected to the tractor and is moved by traveling of the tractor, the tilling means 7 performs the tilling work, and the groove forming means 8 opens the tilling soil by the tilling means 7 to the left and right, and the field surface portion a The sowing groove b is formed in the sowing groove 9, the sowing means 9 sows the seed W in the sowing groove b, the soil covering means 10 covers the seed sowing W, and the pressure reducing wheel 11 is covered. The portion where the seed W is sown is pressed.

  At the time of such work, for example, as shown in FIG. 5 (a), when the foreign matter S such as the previous crop or weed remains, the foreign matter S is cultivated as shown in FIG. 5 (b). It is cut by the bending claw 19 of the means 7 and defeated, and is removed from the front position of the covering soil rotating disk 29 which is the soil covering means 10, and as a result, as shown in FIG. At 29, soil covering work is performed to fill the sowing groove b. In addition, as shown in FIG. 5, drainage grooves c are formed by drainage groove forming claws 20 at portions between adjacent seeding grooves b in the field surface portion a.

  As described above, according to the above-described embodiment, the rotary type tilling means 7 includes the bent claws 19 that perform the tilling work at the front position of the soil covering rotating disk 29 that is the soil covering means 10, for example, It is possible to suppress the occurrence of a problem that the foreign matter S such as weeds adversely affects the soil-carrying rotating disk 29, and appropriate soil-covering work can be performed with the soil-covering rotating disk 29. Can be prevented from being eaten by birds, and the productivity of crops can be improved.

  Further, since the tillage means 7 includes the drainage groove forming claw 20 in addition to the straight claw 18 and the bent claw 19, the drainage groove forming claw 20 drains the portion between the adjacent sowing grooves b in the field surface portion a. Groove c can be formed appropriately, and germination is improved by the presence of drainage groove c, and the productivity of crops can be improved.

  In the above embodiment, the description has been given of the case where two bent claws 19 are provided for one flange portion 17 of the tilling shaft 15. However, the number of the bent claws 19 is arbitrary, and one flange portion 17 is provided. For example, one provided with one bent claw 19 or three or more bent claws 19 may be used.

  Moreover, it is not limited to what seeds and fertilizer are sown as the seeds W to be sown by the sowing means 9, for example, those that sow only seeds, those that sow only fertilizers, those that sow only drugs, those that sow seeds and drugs, Good.

It is a side view which shows one Embodiment of the agricultural machine of this invention. It is a top view of an agricultural working machine same as the above. It is a side view of the cultivation means of a farm working machine same as the above. It is a rear view of the cultivation means of an agricultural working machine same as the above.
