  An embodiment of an agricultural machine according to the present invention will be described with reference to FIGS. 1 and 2.

  1 and 2, reference numeral 1 denotes an agricultural machine. The agricultural machine 1 performs a tilling operation while moving forward by the traveling of the tractor in a state where the agricultural machine 1 is connected to a tractor (not shown) that is a traveling vehicle, for example. A rotary tiller (a rotary with a prep for making a potato floor). In addition, after the tilling work by the farm work machine 1, the post work such as the upright work is performed.

  And this farm work machine 1 is equipped with the body 2 connected with the three-point link part of the tractor.

  The airframe 2 has a chain case portion 3 and a bracket portion (not shown) that are spaced apart from each other on both the left and right sides. Between the chain case portion 3 and the bracket portion, a universal joint or the like is connected to the PTO shaft of the tractor. A rotary cultivating body 5 is provided for performing a cultivating operation while rotating in a predetermined direction, for example, an up-cut direction by power from the connected input shaft 4 side.

  The rotary tiller 5 has a longitudinal tillage shaft 6 in the left-right direction, and a plurality of radially extending tillage claws 7 are arranged in parallel at intervals in the axial direction.

  In addition, the body 2 has a support frame portion 11 that is long in the left-right direction at the front lower portion, and the support frame portion 11 is an abbreviation of the rotary tiller 5 at a position in front of the rotary tiller 5 provided in the body 2. Located over the entire width, a soil derivative (advance) 12 is provided that guides the soil in the field from a position deeper than the rotary cultivator 5 toward the tiller shaft 6 rearward and obliquely upward.

  That is, a plurality of slanted guiding plates 13 having a front, a rear, and a height are arranged at equal intervals in the longitudinal direction of the support frame portion 11 in the circular pipe-shaped support frame portion 11 that is long in the left-right direction of the machine body 2. The plurality of earth guide plates 13 are disposed so as to be distributed over substantially the entire length of the support frame portion 11.

  For example, a substantially triangular tapered portion 14 is formed on the front end side of each metal soil guide plate 13, and the front end of each soil guide plate 13 is located below the lower end of the rotary tiller 5 during work, and each soil guide The rear end of the plate 13 is located below the tilling shaft 6 and above the lower end of the rotary tiller 5 during operation. The plurality of soil guide plates 13 constitute a soil derivative 12.

  Further, the machine body 2 is provided with a cover body 21 for preventing soil scattering covering the upper part and the side part of the rotary tiller 5. The cover body 21 has a pair of left and right side plate portions 22 that are spaced apart from each other, and the upper end and the rear end of both side plate portions 22 are integrally connected by a connecting plate portion 23. The connecting plate portion 23 of the cover body 21 has an upwardly curved curved surface portion 24 formed in a curved surface shape so as to be largely separated from the rotary tiller 5.

  On the other hand, the machine body 2 has a longitudinal frame portion 26 in the left-right direction, and the frame portion 26 is provided with a comb-like screen 27 for separating a large earth lump, stone, or the like and reducing the earth lump.

  The screen 27 is disposed in a substantially arc shape along the movement trajectory of the outer periphery of the rotary tillage body 5, that is, the tip of the tillage claw 7, at a position near the upper side of the rotary tillage body 5. It is located between the upper surface and the curved surface portion 24 of the cover body 21. The screen 27 has a plurality of substantially arc-shaped rod-shaped members 28 arranged in the left-right direction, and a soil discharge gap 29 is formed between the adjacent rod-shaped members 28 to allow only a desired size of mass to pass therethrough. Yes. It should be noted that a lump or stone of a size that cannot pass through the soil discharge gap 29 falls along the rod-shaped member 28 to the rotary tiller side.

  A pair of left and right gauge wheels 30 are provided on the front side of the body 2 so that the vertical position can be adjusted.

  Next, the operation and the like of the one embodiment will be described.

  When plowing work is performed using the farm work machine 1, the farm work machine 1 is connected and attached to the three-point link part of the tractor by connecting the machine body 2 to a three-point link part of the tractor (not shown).

  Then, after actuating the three-point link part of the tractor in the field and lowering the farm work machine 1 by a desired amount, when the farm work machine 1 is moved forward by the traveling of the tractor, the soil in the field is cut by the soil derivative 12. After that, it is guided obliquely upward, and is cultivated by the rotary tiller 5 rotating in the upcut direction.

  The lump that has been crushed by the rotary tiller 5 and has a size less than desired is passed through the soil discharge gap 29 of the screen 27 and guided by the curved surface portion 24 of the cover body 21 and falls. It should be noted that large blocks or stones that cannot pass through the soil discharge gap 29 are guided by the rod-shaped member 28 of the screen 27 and fall prior to a block of less than desired size.

  In this way, when the farming machine 1 is used for the tilling work, the soil derivative 12 having substantially the same working width as that of the rotary tiller 5 at the front position of the rotary tiller 5 rotating in the upcut direction. Since the soil in the field is cut and then guided obliquely upward toward the tilling shaft 6 side, it becomes difficult to form a hard cultivator on the field compared to conventional tilling and crushing machines, etc. Two layers consisting of the lower layer are formed, and an optimum floor for a farm product can be easily formed. In addition, workability can be improved by reducing traction resistance.

  In addition, the agricultural working machine 1 is not limited to the one provided with the rotary tiller 5 that performs the tilling work while rotating in the upcut direction. For example, as illustrated in FIGS. 3 and 4, the tiller while rotating in the downcut direction. The same operation and effect can be achieved even with the rotary tiller 5 that performs the work.

  Unlike the up-cut type farming machine 1 shown in FIG. 1, this down-cut type farming machine 1 is located at the rear position of the rotary tiller 5 and the screen 27 is placed on the screen 27 from the rotary tiller 5 side. Accepts large clots (such as large clots and stones that cannot pass through the soil discharge gap 29) sent along the side, and transports them to the side, for example, to the left in the direction of travel, and the transverse feed conveyor 31 that reduces the clot at the rear. I have.

  The transverse feed conveyor 31 is constituted by a rod conveyor composed of, for example, a chain 32 and a rod 33, and is disposed at a position behind the rotary tiller 5 and below the cover 21. The transverse conveyor 31 is driven by receiving power from the input shaft 4 side.

  The screen 27 shown in FIG. 3 differs from that shown in FIG. 1 in a substantially arcuate shape along the movement trajectory of the outer periphery of the rotary tiller 5, that is, the tip of the tillage claw 7, at a position near the lower side of the rotary tiller 5. It is arranged. In other words, the front end of the screen 27 is positioned in the vicinity of the soil derivative 12, and the rear end of the screen 27 is positioned in the vicinity of the transverse feed conveyor 31.

  When the farming machine 1 is used to perform the tilling work, the soil derivative 12 having substantially the same work width as the rotary tiller 5 at the position in front of the rotary tiller 5 rotating in the downcut direction is the field. After the soil is cut and guided obliquely upward toward the tillage shaft 6 side, a lateral feed conveyor 31 having a conveyance length substantially the same as the rotary tillage body 5 at the rear position of the rotary tillage body 5 is provided on the rotary tillage body 5 side. Since large soil blocks, stones, etc. are transported to the side, it becomes difficult to form a hard cultivator on the field compared to conventional tillers and the like, and an optimal floor for farm products can be easily created.

  The soil derivative 12 is not limited to the soil guide plate 13 that is a plurality of divided plates positioned in an inclined shape, and is composed of, for example, a single plate member that is long in the left-right direction. It may be a dish.

  The soil derivative 12 may be fixed to the support frame portion 11 of the body 2 or may be detachably attached to the support frame portion 11.

  Further, the transverse feed conveyor 31 may be configured to selectively switch the transport direction of the clot between the right side in the traveling direction and the left side in the traveling direction.
