Description

  The present invention relates to an agricultural machine.

  As a conventional agricultural machine, a seeder 81 described in Patent Document 1 is exemplified. As shown in FIG. 8, the seeder 81 includes a machine body 84 including a pair of left and right side frames 84a and 84a, and a horizontal frame 84b connecting the both side frames 84a and 84a. Both side frames 84a, 84a are extended in the front-rear direction, and between the both side frames 84a, 84a, a grounding wheel 82, a seeding device 85, a grooving device (not shown), a cover plate 100, a pressure reducing wheel 83, etc. Each functional element part is supported.

JP-A-9-107731

  However, since each functional element portion is disposed between the both side frames 84a and 84a, each function element portion is replaced when each functional element portion is replaced or when consumables in each functional element portion are replaced. There is a problem that it is difficult to attach and detach the element part. In particular, functional elements that rotate about a shaft extending left and right, such as a grounding wheel 82, a feeding roll (not shown) of the seeding device 85, a pressure reducing wheel 83, and the like, are supported by both side frames 84a and 84a at both ends of the shaft. Furthermore, since the shaft may be provided with a drive element (engine, motor, sprocket, gear, etc.) for rotationally driving the shaft, it is difficult to attach and detach.

In order to solve the above problems, the agricultural machine of the present invention is:
A plurality of functional element portions arranged in approximately one direction, and a machine body that cantilever-supports each functional element portion from the left or right side with respect to the one direction,
Each functional element portion is supported by the machine body so as to be detachable to the opposite side of the one side.

  Although it does not specifically limit with the said functional element part, A wheel (A grounding wheel and a pressure-reducing wheel are included), Agricultural work apparatus (For example, a sowing apparatus, a fertilizer, a medicine application apparatus, a ditching apparatus, a soil covering apparatus, a cultivation apparatus, a transplanting apparatus, etc. And the like), a hopper, a drive mechanism (a prime mover (engine, motor, etc.), a power transmission mechanism, etc.) and the like.

  According to this configuration, since each functional element portion is cantilevered from the one side by the airframe, the opposite side of the one side can be widely released. For this reason, it can be easily attached to and detached from the opposite side. Moreover, since this structure is simple, it can be realized at low cost.

  According to the agricultural machine according to the present invention, it is possible to easily attach and detach functional element parts such as wheels and seed feeding parts from the machine body.

  FIGS. 1-6 has shown the seeding machine as a farm working machine of 1st embodiment which actualized this invention. As shown in FIGS. 1 to 3, the seeder 1 includes a machine body 4 that is supported by a drive wheel 2 and a pressure-reducing wheel 3 as front and rear wheels, and a seed feeding unit 5 that feeds seeds as a granular body. And a transmission mechanism 6 that transmits the rotation of the drive wheel 2 to the seed feeding portion 5, and a groove excavation covering portion 7 that forms a groove for burying seeds in the field H and that covers the soil after bringing the soil into the groove after sowing. And a handle 8 for maneuvering the airframe 4 and configured to sow seeds as the airframe 4 advances. The seeder 1 includes a drive wheel 2 as a functional element part, a seed feeding part 5, a ditch covering part 7, and a pressure reducing wheel 3 arranged in a line in a substantially moving direction of the machine body. The airframe 4 is cantilevered from the left with respect to the airframe traveling direction. In each figure, arrow F indicates the front side of the aircraft.

  The airframe 4 is formed so as to extend substantially linearly in the front-rear direction when seen in a plan view, and a central portion thereof is bent toward the upper rear and obliquely upward.

  A driving wheel shaft 11 extending in the left-right direction is rotatably supported on the front side portion of the body 4, and the driving wheel 2 is not rotatable relative to the driving wheel shaft 11 on the right side of the driving wheel shaft 11. It is attached with a nut 12 as a fixing means so as to be detachable. A stand 13 is provided on the front side of the drive wheel shaft 11 in the body 4. The stand 13 is supported by the machine body 4 so as to be rotatable between a retracted position P11 indicated by a solid line in FIG. 5 and a machine body support position P12 indicated by a two-dot chain line in FIG. As shown in FIG. 5, the retracted position P11 can be used by supporting the handle 8 in a folded state or by making it a handle for transporting the aircraft.

  A seed feeding unit drive shaft 15 extending in the left and right directions for driving the seed feeding unit 5 is rotatably supported at the center of the body 4, and substantially above the seed feeding unit driving shaft 15 in the seed feeding unit 5. Is provided with a seed feeding part support part 16. The rotation of the drive wheel shaft 11 is transmitted to the left side of the seed feeding portion drive shaft 15 by a transmission mechanism 6 (for example, a chain transmission mechanism). The right side portion of the seed feeding unit drive shaft 15 is inserted into an input shaft 17 incorporated in the seed feeding unit 5 so as not to be relatively rotatable and detachable, and is fixed by pins 18 and 19. The seed feeding part support part 16 is provided with a through hole (not shown) facing left and right, and a projecting part 20 projecting leftward from the seed feeding part 5 is fitted into the through hole, It is fixed with a pin 22. Further, on the front side of the seed feeding part drive shaft 15 in the central part of the machine body 4, a groove digging soil support part 25 that supports the groove digging soil part 7 is provided. The grooving cover part support part 25 can adjust the vertical position of the support hole 26 into which the mounting pole 43 projecting upward from the grooving cover part 7 is inserted and the mounting pole 43 inserted into the support hole 26. And a position fixing screw 27 for fixing to the position. The position fixing screw 27 can be operated from the right side, which is the opposite side of the machine body 4 in the grooving covering portion 7.

  On the rear side of the body 4, legs 30 are provided that extend obliquely downward and rearward to support the pressure-reducing wheel 3. A pressure-reducing wheel shaft 31 extending to the right side is attached to the tip of the leg portion 30, and a rotatable pressure-reducing wheel 3 and the pressure-reducing wheel 3 are formed on the right-hand side portion of the pressure-reducing wheel shaft 31. A substantially U-shaped scraper 32 is attached by a nut 33 as a fixing means so as to be detachable in the right direction. Further, a foldable handle 8 is provided behind the leg 30 in the body 4.

  The driving wheel 2 and the pressure-reducing wheel 3 have water-absorbing sponges 2a and 3a detachably attached to their outer circumferences. Since the drive wheel 2 is simply cantilevered from the left side of the machine body 4, the water absorbing sponge 2 a can be exchanged without being removed from the machine body 4. Further, with respect to the pressure reducing wheel 3, the water absorbing sponge 3 a can be replaced only by removing the nut 33 and the right end side of the scraper 32 from the pressure reducing wheel shaft 31.

  As shown in FIG. 4, the handle 8 includes an upper handle 35 extending left and right and a handle arm 36 extending front and rear. The handle arm 36 can be bent back and forth between the folding position P21 supported by the stand 13 at the retracted position P11 and the rearward tilt position P22 extending obliquely upward from the rear of the body 4 with respect to the rear end portion of the body 4. In addition, it is configured so that the position can be appropriately fixed by the fixture 37 between the substantially upright position and the rearward tilt position P22. A U-shaped holder member 38 is attached to the distal end of the handle arm 36 so as to be able to turn left and right. An upper handle 35 is slidably inserted into the holder member 38, and the upper handle 35 is secured to the handle arm by a fastening bolt 39 screwed to the holder member 38. 36 is fastened and fixed. At this time, as shown in FIG. 4A, when the side surface of the upper handle 35 is fixed in a state where the side surface of the upper handle 35 is in contact with the distal end surface of the handle arm 36, the upper handle 35 extends in the left-right direction. It becomes ready for use. The upper handle 35 can be adjusted to the left and right with respect to the attachment position with respect to the handle arm 36. Therefore, for example, when seeding on a ridge, an operator walks in a valley away from the center of the machine body, so that the mounting position can be adjusted appropriately so that the upper handle 35 protrudes to the valley side ( Instead of the handle, a bespoke eccentric handle was attached to the fuselage 4). Further, as shown in FIG. 4B, the tightening bolt 39 is loosened and the upper handle 35 is rotated together with the holder member 38, whereby the side surface of the upper handle 35 is moved to the handle arm 36 as shown in FIG. When the upper handle 35 and the handle arm 36 are parallel to each other, a compact state is obtained. Then, as shown in FIG. 5, when the handle 8 in this state is rotated to the folding position P21, the handle 8 is in the storage state, and the storage space can be reduced.

  As shown in FIG. 6, the ditch covering soil portion 7 includes a ditcher 41 formed in a boat shape, a earthing plate 42 attached to the rear side of the ditcher 41, and a front upper end of the ditcher 41. And a mounting pole 43 that is erected on the unit and is mounted on the body 4 so that the relative vertical position can be adjusted. The groove digger 41 has a substantially V-shaped groove forming tool 44 detachably attached to the bottom of the groove digger 41 so that it can be exchanged for another groove forming tool 44 according to the desired groove shape. It has become. Therefore, it is not necessary to replace the entire trench excavator 41 according to the groove shape.

  According to the seeder 1 of the present example configured as described above, the drive wheel 2, the seed feeding unit 5, the ditching covering soil unit 7, and the pressure-reducing wheel 3 as the functional element unit are arranged in a substantially advancing direction. Since each functional element portion is cantilevered from the left side with respect to the aircraft traveling direction, the right side can be widely released. Then, as indicated by a two-dot chain line in FIG. 3, each functional element portion is supported by the machine body 4 so as to be detachable to the right side, which can be easily detached and attached to the right side. Moreover, since the seeder 1 of the present invention has a simple structure, it can be realized at low cost.

  Next, FIG. 7 shows a seeding machine 50 as a farm working machine according to a second embodiment that embodies the present invention. This seeder 50 is mainly different from the first embodiment in the following points. Accordingly, portions common to the embodiment are given the same reference numerals, and redundant description is omitted.
