Description

  The present invention relates to a transplanter equipped with a preliminary seedling transfer device.

Conventionally, a planting work machine is connected to the rear of a traveling machine body provided with a driver's seat, and a spare seedling transfer device is provided on the side of the traveling machine body to supply spare seedlings on the traveling machine body from the edge of the traveling machine body. However, a transplanter from the front of the traveling machine body to the side of the seat in the driver's seat is known.
JP 2005-17680 A

  In the transplanter, preliminary seedling transfer devices are provided on the left and right sides of the traveling machine body. For this reason, the access to the driver's seat is hindered by the spare seedling transfer device, and there is a drawback that it cannot be easily performed from either the left or right side of the seat. For example, by folding the preliminary seedling transfer device, it is possible to provide a space on the side of the seat so that the driver can get on and off the space. However, it is not easy to get on and off.

  The transplanting machine of the present invention for solving the above-described problems is that the planting work machine 2 is connected to the rear of the traveling machine body 1 provided with the driver's seat 8, and the side of the traveling machine body 1 is on the traveling machine body 1. A preliminary seedling transfer device 18 for replenishing the preliminary seedling 15 is provided, and in the transplanter from which the preliminary seedling transfer device 18 extends from the front of the traveling machine body 1 to the side of the seat 7 in the driver's seat 8, 18 is disposed on either the left or right side of the traveling machine body 1, and on the other side, a spare seedling stage 19 for placing the spare seedling 15 is provided, and the preliminary seedling stage 19 is disposed at a position ahead of the seat 7. Is the first feature.

  Secondly, a transmission lever 12 for setting and adjusting the traveling speed of the traveling machine body 1 is provided. The transmission lever 12 is arranged on either the left or right side in front of the seat 7, and the preliminary seedling transfer device 18 is connected to the transmission lever 12. It is provided on the arrangement side.

  According to the structure of the present invention configured as described above, the side on which the spare seedling stage is arranged is left empty on both the left and right sides of the seat. It becomes easy to use. For example, there is an advantage that the driver can easily get on and off by using the space as a space for getting on and off.

  By providing a speed change lever for setting and adjusting the traveling speed of the traveling machine body, the speed change lever is arranged on either the left or right side in front of the seat, and the spare seedling transfer device is provided on the speed change lever arrangement side. Since the speed change lever is not located on the side of the space for getting on and off the vehicle, it is possible to prevent inconveniences such as a change of the traveling speed when the driver touches the speed change lever when getting on and off the driver. .

  1 and 2 are a side view and a plan view of a riding rice transplanter which is a transplanter adopting the present invention. In this riding rice transplanter, a planting work machine 2 is connected to the rear of the traveling machine body 1 so as to be movable up and down, as in the prior art. A mat seedling is placed on a seedling mount 3 provided in the planting work machine 2, and the planting part 4 is operated by operating the planting part 4 of the planting work machine 2 while the traveling machine body 1 is traveling. The seedlings are scraped off from the mat seedlings on the stage 3 and are planted in the field, and the seedlings are planted.

  A bonnet 6 is provided in front of the traveling machine body 1. Behind the bonnet 6 is provided a driver's seat 8 having a seat (seat) 7 located at the center of the left and right. A front operation panel 9 is provided in front of the seat 7. The front operation panel 9 is provided with a steering handle 11.

  The steering handle 11 is located at the left and right center of the traveling machine body 1. A shift lever 12 for shifting the driving force from the engine is provided on the left side of the steering handle 11 in the front operation panel 9. The speed change lever 12 is provided so as to be swingable back and forth and right and left. The traveling speed of the traveling machine body 1 is adjusted and set by operating the speed change lever 12.

  Front steps 13 are provided on the left and right sides of the bonnet 6. A driver's seat step 14 constituting the floor of the driver's seat 8 is provided so as to extend from the front of the seat 7 to the side. The machine body cover 16 that covers the lower side of the seat 7 is formed with flat seedling supply steps 17 that are one step higher than the driver's seat step 14 and located on both the left and right sides of the seat 7.

  The operator can freely move between the front step 13 and the seedling supplying step 17 through the driver's seat step 14. By the front step 13, the driver's seat step 14, and the seedling supplying step 17, a moving path through which the worker moves from the front side to the rear side of the traveling machine body 1 is formed on the side part of the traveling machine body 1 (side from the seat 7). Forming.

  A spare seedling transfer device 18 for transferring a spare mat seedling (preliminary seedling) to be replenished to the seedling mount 3 from the heel is attached to the left side of the bonnet 6. A spare seedling stage 19 on which the preliminary seedlings 15 are placed in advance is attached to the right side of the bonnet 6. The spare seedling mount 19 is disposed on the side opposite to the transmission lever 12 with the sheet 11 interposed therebetween, and the preliminary seedling transfer device 18 is disposed on the transmission lever 12 side.

  The preliminary seedling stage 19 is supported by the traveling machine body 1 via a stay 21 provided on the right side of the traveling machine body 1. The preliminary seedling stage 19 has a front-rear length that extends slightly from the rear position to the vicinity of the rear end position of the front operation panel 9 from the front end position of the bonnet 6. The preliminary seedling stage 19 does not reach the side of the sheet 7.

  The preliminary seedling transfer device 18 includes a fixed seedling base 22 fixed to the traveling machine body 1 side, a first seedling base 23 positioned in front of the fixed seedling base 22, and a second seedling base positioned behind the fixed seedling base 22. 24.

  The first seedling table 23 and the second seedling table 24 are connected to the fixed seedling table 22 so as to be rotatable. A support frame 27 is integrally attached to the bottom surface side of the fixed seedling base 22 via a fixed plate 26. Brackets 28 are attached to the front and rear of the support frame 27 on the bottom side.

  On the other hand, stays 29 are provided on the left and front sides of the traveling machine body 1. As shown in FIG. 3, the lower end portion of the stay 29 is attached to the traveling machine body 1 side and protrudes upward. The upper end side of the stay 29 is curved outward and is generally horizontal.

  A base plate 31 is attached to the upper end portion of the front stay 29 that is substantially horizontal, and a base plate 32 is attached to the upper end portion of the rear stay 29 that is substantially horizontal. The base plates 31 and 32 correspond to the front and rear brackets 28, respectively. The brackets 28 corresponding to the base plates 31 and 32 are fixed by bolts 33.

  Thereby, the fixed seedling stand 22 is attached to the traveling machine body 1, and the preliminary seedling transfer device 18 is attached to and supported by the traveling machine body 1. The preliminary seedling transfer device 18 partially overlaps the front step 13, the driver's seat step 14, and the supply step 17 in plan view. Thereby, the preliminary seedling transfer device 18 is substantially accommodated within the width of the seedling placing stand 3.

  The outer end position of the preliminary seedling transfer device 18 and the outer end position of the seedling mounting table 3 are substantially the same in plan view, and the preliminary seedling transfer device 18 has a machine width excluding the preliminary seedling transfer device 18 of the riding rice transplanter. The preliminary seedling transfer device 18 is accommodated within the width of the machine body. However, the movement path on the left side is in a state where the preliminary seedling transfer device 18 enters.

  As shown in FIG. 1, the preliminary seedling transfer device 18 includes a deployment posture A in which the seedling stands 22, 23, and 24 are deployed in a straight line in a side view, and a first seedling stand as shown in FIG. 4. 23 and the 2nd seedling stand 24 have become a folding type in which the posture can be switched to a folding posture B that is in a folded state folded above the fixed seedling stand 22.

  The preliminary seedling transfer device 18 in the deployed posture A is in a tilted posture that is low before and after. In the unfolded posture A, the preliminary seedling transfer device 18 has a front end of the first seedling base 23 protruding forward from a front end of the traveling machine body 1 and a rear end of the second seedling base 24 on the seedling mounting base 3 of the planting work machine 2. It is located near the upper portion of the seedling supplying step 17 so as to be close to each other. As a result, the preliminary seedling transfer device 18 in the deployed posture A passes from the front of the traveling machine body 1 to the side of the seat 7 and reaches the vicinity of the front end of the seedling mount 3.

  Each of the seedlings 22, 23, 24 has a structure in which a roller shaft 37 in which a roller is integrally formed on the shaft is rotatably attached between the left and right side plates 36. When the preliminary seedling 15 is placed on the roller shaft 37 from the front end of the first seedling stand 23 in the preliminary seedling transfer device 18 in the unfolding posture A, the seedling box of the preliminary seedling 15 is a roller of the roller shaft 37. The preliminary seedling transfer device 18 is in contact with the second seedling stand 24 and is sequentially moved by its own weight toward the rear end of the second seedling stand 24 by the inclination of the preliminary seedling transfer device 18.

  The preliminary seedling 15 is moved smoothly because the roller shaft 37 rotates to guide the seedling box. The spare seedling transfer device 18 is in the form of a roller conveyor in the unfolded posture A, the front end of the first seedling stand 23 is positioned at the heel, and the first seedling pedestal 23 is replenished with the spare seedling 15 from the heel. A plurality of preliminary seedlings 15 can be continuously supplied to the transfer device 18. A plurality of preliminary seedlings 15 can be placed and stocked up to the full length of the preliminary seedling transfer device 18.

  The operator can easily replenish seedlings on the seedling stage 3 by standing at the seedling supply step 17 and placing the spare seedling 15 on the rear end side of the second seedling stage 24 on the seedling stage 3. After replenishing seedlings from the spare seedling 15 at the end of the second seedling stand 24 to the seedling placing stand 3, the seedling box and scraper of the spare seedling 15 are put into a scraper tray 38 provided in the preliminary seedling transfer device 18. be able to.

  When the seedling box or scraper of the spare seedling 15 is put into the scraper tray 38 and lowered from the seedling stand, the front spare seedling 15 moves on the roller shaft 37 due to its own weight and becomes the next replenishment candidate for the seedling placing stand 3. A seedling can be replenished to the mounting table 3 sequentially. The scraper tray 38 is provided inside the traveling machine body of the preliminary seedling transfer device 18.

  The height of the second seedling stand 24 is about the height position of the steering handle 11 described above so that an operator standing at the seedling supply step 17 can easily take the mat seedling from the rearmost spare seedling 15. It is set high to some extent. As a result, the operator can easily take the spare seedling 15 and supply it to the seedling stage 3 with little bending. In addition, the replenishment of the spare seedling 15 from the heel is facilitated, the operator's working posture is improved, and fatigue is reduced.

  Since the rear end of the second seedling stand 24 is relatively high as described above, the position of the front end of the first seedling stand 23 is relatively high. For this reason, even when the preliminary seedling transfer device 18 is in the deployed posture A and the fertilizer tank for fertilization is arranged below the first seedling stand 23, fertilizer such as paste fertilizer is supplied to the fertilizer tank from the supply port on the upper surface side. Can be easily supplied. In addition, it is possible to replenish the spare seedling 15 from the front end of the first seedling stand 23 to the spare seedling transfer device 18 directly from a truck or the like.

  The preliminary seedling transfer device 18 can also expand only the first seedling stand 23 in a state of being folded above the fixed seedling stand 22. By setting only the first seedling base 23 in the folded state, the preliminary seedling 15 can be supplied to the preliminary seedling transfer device 18 from the front end of the fixed seedling base 22. When the distance from the heel to the traveling body 1 is relatively close, the spare seedling 15 can be easily replenished.

  The preliminary seedling 15 is placed on the upper part of the first seedling base 23 in the folded state (the lower part of the first seedling base 23 in the unfolded state A), and the first seedling base 23 is used as a normal auxiliary seedling stage. You can also. When the first seedling stand 23 is in the folded state, the spare seedling transfer device 18 hardly protrudes in front of the bonnet 6, so that the traveling performance of the traveling machine body 1 is high.

  In addition, since the preliminary seedling stage 19 can be folded when unnecessary as in the prior art, the preliminary seedling stage 19 and the preliminary seedling transfer device 18 almost protrude from the body width excluding the preliminary seedling transfer device 18 of the riding rice transplanter. The passenger rice transplanter can be stored in a space in the range of approximately the body width.

  The bonnet 6 can be opened and closed integrally with the front step 13. The preliminary seedling transfer device 18 and the preliminary seedling mount 19 do not hinder the integral opening and closing of the bonnet 6 and the front step 13.

  As described above, since the spare seedling stage 19 is not located on the right side of the sheet 7, the right side of the sheet 7 is an empty space. Therefore, access to the driver's seat 8 can be easily performed using the space. For example, the driver can easily get on and off using the above space as a space for getting on and off.

  At this time, the empty space is provided on the opposite side of the speed change lever 12 with the seat 7 interposed therebetween. For this reason, when the driver's seat 8 is accessed through the space, for example, when the driver gets on and off, the possibility that the driver accidentally contacts the speed change lever 12 is extremely low. The inconvenience of swinging 12 is prevented.

  On the other hand, the spare seedling transfer device 18 overlaps above the front step 13, the driver's seat step 14 and the supply step 17, so that the preliminary seedling transfer device 18 becomes an obstacle and it is difficult to move on the steps 13, 14, and 17. It becomes.

  For this reason, the movement of the movement path on the shift lever 12 side is restricted, and the inconvenience that the shift lever 12 is swung due to erroneous contact with the shift lever 12 during the movement of the movement path is prevented. In any case, if the shift lever 12 is swung, there is a disadvantage that the setting of the traveling speed of the traveling machine body 1 is changed, and this inconvenience can be prevented.

  In addition, by making the preliminary seedling transfer device 18 into the folding posture B, or by bringing only the second seedling stand 24 into a state folded above the fixed seedling stand 19, at least the second seedling stand 24 is brought into the folded state. An empty space is formed on the left side of the sheet 7. Accordingly, the driver's seat 8 can be accessed from the left side of the seat 7 using the space.

  However, since the shift lever 12 is provided on the left side of the seat 7, when the driver's seat 8 is accessed using the space formed on the left side of the seat 7, the shift lever 12 is provided on the right side of the seat 7. Compared to the case where the driver's seat 8 is accessed using the formed space, there is a higher risk that the traveling speed of the traveling machine body 1 may be erroneously changed by contacting the shift lever 12.

  The spare seedling transfer device 18 is attached so that the rear end is positioned in front of the forward / backward swing operation range of the transmission lever 12 when the second seedling stand 24 is folded as described above. For this reason, in the folded state of the second seedling table 24, even if the speed change lever 12 is swung forward, the speed change lever 12 and the spare seedling transfer device 18 do not contact each other.

  Accordingly, when the second seedling stand 24 is in the folded state, the spare seedling transfer device 18 can be attached to the traveling machine body 1 in a state of being closer to the side surface of the bonnet 6, and the preliminary seedling transfer device 18 is more compact on the traveling machine body 1. Can be attached to. In addition, the attachment position with respect to the traveling body 1 of the preliminary seedling transfer device 18 can be easily performed by changing the bolt fixing position between the base plates 31 and 32 and the corresponding bracket 28. For example, the preliminary seedling transfer device 18 may be attached so as to be located outside the front step 13, the driver's seat step 14, and the supply step 17.
