Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a multi-row planter for planting seedlings while laying a multi-sheet such as paper on the rice field.

[0002]

[Prior art]

 Conventionally, Japanese Patent Laid-Open No. 5-276839 is known as a multi-rice transplanter.

[0003]

[Problems to be solved by the device]

 When the above-mentioned planting work is performed, when the final planting process at the ridge is transplanted, if the number of planting rows of the rice planting machine does not match the number of remaining planting work rows, an operation generally called ridge treatment In other words, in the previous process, the planting of several rows is stopped and the number of planting rows is adjusted, but it is difficult to adjust the edge treatment of paper sheets, and the entire number of planting rows is laid. As a result, a surplus will occur. Therefore, when the final planting process is transplanted, the traveling wheels step on the remaining portion of the paper sheet laid in the previous process, and in particular, the front wheel causes the paper sheet to be dragged into the paddy field. There was a risk that the paper sheet that had been planting seedlings in the process was pulled and moved, disturbing the planted seedlings.

In addition, a plurality of multi-seat support members are provided below the multi-sheet feeding and laying mechanism of the planting section to prevent the multi-sheet from sagging when the planting section B is raised when the machine is traveling. If present, there was a risk that the multi-sheet would catch on the multi-sheet support rod and press and move the paper sheet, disturbing the planted seedlings. In addition, in the headland, it is very difficult to align the position of the paper sheet end part at the planting start part and the planting end part in a horizontal line, and the paper sheet end part becomes inevitable. Therefore, the same problem as above occurs when planting the headland part, and there is a problem that the running wheels and the multi-sheet support member may drag the paper into the seedlings and disturb the seedlings already planted.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a cutting mechanism for cutting a multi-seat that is placed in front of a traveling wheel and laid on a rice field in the front part of a traveling machine body. A plurality of the multi-seat support members are provided in correspondence with the planned passage positions of the traveling wheels and the planned passage positions of a plurality of multi-seat support members provided below the feeding laying mechanism of the planting section.

[0006]

[Action]

 The cutting device is held in the raised position during normal planting work. As described above, during the final planting process or headland planting process, if there is a risk that the paper sheet laid in the previous process will be stepped on by wheels, the cutting device will be lowered to the ground and cut the paper sheet. Put in a state. With the forward movement of the traveling machine body, the paper sheet of the portion corresponding to the planned passage position of the multi-sheet supporting member provided below the feeding laying mechanism of the planting portion at the front portion of the traveling wheel is the cutting blade of the cutting device. Since it will be divided into left and right by the traveling wheel and the multi-seat support member will pass through the dividing position, the traveling wheel and the multi-seat support member will not drag the paper sheet, and the seedlings planted in the previous process will not be dragged. Planting work can be done without disturbing.

【Example】

 Reference numeral A denotes a traveling machine body having traveling wheels such as front wheels 1 and rear wheels 2. The traveling machine body A is provided with a steering wheel 3 and a driver's seat 4, and a hydraulic cylinder mechanism 5 is provided behind the traveling machine body A to move up and down. The planting part B is attached via a lift link mechanism 6 that is driven. The planting section B is equipped with a seedling placing table 7 and a planting mechanism 8, and below the seedling placing table 7 is a roll case 9 for storing a multi-sheet roll SR of paper, vinyl, etc. and a feeding unit. A front roller 10, a rear roller 11, and an end pressing roller 12 that press and lay the multi-sheet S on the rice field are provided. Numeral 13 is a multi-seat supporting member for preventing the multi-sheet S from hanging down when the planting part B is raised during traveling of the machine body, etc., and is constituted by a rod-shaped or thin plate-shaped member, the front end side of which is the above-mentioned row. It is attached to the case 9 side, is located between the seedling planting strips, has its rear end side extending rearward along the traveling direction of the machine body, and a plurality of planting parts B are arranged in the left-right direction. 14 is a cutter mechanism that is attached to the planting section B side and cuts the multi-sheet S at the end of planting. The cutter mechanism 14 is normally held in standby at the raised position shown by the solid line and is operated during cutting. The multi-seat S is cut by being appropriately remote-controlled from the seat 4 to descend to the descending position shown by the chain line.

A cutting mechanism C for cutting a surplus portion of the multi-sheet S laid on the rice field in the previous step is arranged in the front part of the traveling machine body A. The cutting mechanism C is supported by a front-rear direction shaft 15-1 pivotally supported on the front part of the traveling machine body A so as to be rotatable left and right, and is supported so as to be vertically rotatable about an axis of the horizontal shaft 15. There is. Arms 16 are mounted on both sides of the horizontal shaft 15, and a rotary shaft 17 is rotatably mounted on the ends of the left and right arms 16, 16. Reference numeral 18 denotes a plurality of cutting blades mounted on the rotary shaft 17, and the cutting blades 18 are formed in a circular saw shape so that the front wheels 1 and the rear wheels 2 and the like of the traveling wheels are seen in a plan view. A plurality of them are arranged in front of the planned passage position and in front of the planned passage position of the multi-seat support member 13. Numerals 19 and 19 are sleds rotatably supported on both sides of the rotary shaft 17, and the cutting blades 18 are projected downward through elongated holes 20 formed in the sleds 19. Therefore, the cutting blade 18 is guided by the sled member 19 that slides on the upper surface of the laid multi-sheet S, and the multi-sheet S is reliably pressed by the sled member 19 without any slack, so that the cutting blade 18 can reliably perform the operation. To be cut and separated.

Reference numeral 21 denotes a spring stretched between the base end of the arm 16 and the traveling body A side, and the cutting blade 18 and the sled body 19 are elastically pressed toward the rice field by the spring 21, and the rice field is undulated. The upper and lower parts of the multi-sheet S are adjusted in accordance with the above to ensure the cutting action of the multi-sheet S. One end of the wire 22 is locked to the intermediate portion of the arm 16, and the other end of the wire 22 is connected to the hydraulic cylinder mechanism 5. With this connection configuration, when the hydraulic cylinder mechanism 5 extends in the direction of raising the planting portion B, the wire 22 is pulled, the arm 16 is pulled up against the elasticity of the spring 21, and the cutting blade 18 and the sled body 19 are pulled up. Flies above the paddy field and can be lifted to an elevated position. On the contrary, when the hydraulic cylinder mechanism 5 is contracted in the direction of lowering the planting part B, the wire 22 is loosened, and the elastic force of the spring 21 and the weight of the arm 16, the cutting blade 18, the sled body 19 and the like cause the arm 16 to descend. The sled body 19 contacts the upper surface of the multi-sheet S laid in the previous step and is prevented from descending, and at the same time, the multi-sheet S is cut by the cutting blade 18. As described above, the cutting mechanism C including the cutting blade 18 and the like is configured to move up and down in association with the elevation of the planting section B.

Next, the holding mechanism D that holds the cutting mechanism C in the raised position will be described. Reference numeral 23 is a locking pin capable of supporting the lower part of the arm 16, and the locking pin 23 is constantly urged in a protruding direction by a spring 24 and is connected to an operating lever 26 via an operating wire 25. Has been done. The operation lever 26 is configured to be switchable between a lock operation position X and a release operation position Y of the operation guide 24. Then, when the operation lever 26 is set to the lock operation position X, the locking pin 23 is biased by the spring 24 and comes into the ascending / descending locus of the arm 16 to support the lower part of the arm 16. It becomes possible to hold the cutting mechanism C in the raised position. Further, when the operation lever 26 is set to the release operation position Y, the locking pin 23 compresses the spring 24 and is pulled by the operation wire 25 to be pulled out of the ascending / descending movement path of the arm 16 to allow the arm 16 to descend. It is possible to bring the cutting mechanism C to the cutting action position in the lowered state.

During normal planting work, the operation lever 26 is set to the lock operation position X and the cutting mechanism C is held in the raised position. As the traveling machine body A advances, the multi-sheet roll SR accommodated in the roll case 9 is fed out through the upper and lower spaces of the front and rear rollers 10, 11 and the end pressing roller 12 and the sheet support rod 13 and laid on the rice field. The seedlings on the seedling mounting table 7 are scraped off by the planting mechanism 8 one by one, and the multisheet S laid down is pierced and planted on the rice field. When reaching the headland, after the traveling of the traveling machine body A and the planting work are stopped, the cutter mechanism 14 is lowered to cut off the multi-sheet S fed out. Then, when the planting portion B is raised, the multi-sheet S which is fed out below the front and rear rollers 10 and 11 and the end pressing roller 12 is supported by the sheet supporting member 13 and is prevented from hanging downward. Supported by the state. However, when the traveling aircraft body A is swiveled to the headland while the planting section is raised and the planting section B is lowered to the ground at the planting restart position, the unwound multi-seat S is grounded on the paddy field and Since the rollers 10 and 11 and the end pressing roller 12 are pressed, the traveling machine body A can be moved forward and the planting operation can be restarted. Thus, with the cutting mechanism C held in the raised position, the planting work similar to the conventional one can be performed efficiently and quickly.

Then, in the planting process of the ridge or headland part, when the surplus part of the multi-sheet S laid in the previous process remains on the rice field (for example, in the embodiment of FIG. 3, a 5-row rice planting machine) At the time of planting work in front of the ridge, it shows the case of ridge treatment in which only two rows are planted and three rows are stopped and stopped. Therefore, the final stroke is adjusted so that 5 rows can be planted.Therefore, the multi-sheet S is laid in a state where there is a remaining portion on the paddy field equivalent to 3 rows planted.) The lever 26 is set to the release operation position Y, the cutting mechanism C is switched to the lowered cutting action position, and the planting operation is started. Then, the surplus portion of the multi-seat S laid on the rice field is cut by the cutting blades 18, 18 of the cutting mechanism C on the planned passage line of the traveling wheels such as the front wheels 1 and the rear wheels 2 and the multi-seat support member 13 passes. Since it is cut and separated at the position corresponding to the planned line, after that, even if the traveling wheels and the multi-seat member 13 pass, the multi-sheet S on the planted seedling side is not dragged into the rice field and the planted seedlings are not damaged. Planting work can be completed.

Further, when the multi-sheet S is cut by the cutting blade 18, the portions of the multi-sheet S on both sides of the cutting blade 18 are pressed by the sled body 19, so that the cutting action can be surely performed. Further, since the cutting mechanism C can freely roll around the axis 15-1 in the front-rear direction, even if the traveling machine body A rolls left or right due to the unevenness of the tiller, the multi-seat S can smoothly follow the upper and left upper surfaces of the multi-seat S. S can be cut. Although the cutting blades 18, 18 ... Are provided on the single rotary shaft 17 in the embodiment of the present invention, the rotary shaft 17 is divided into left and right parts and the left and right cutting blades 18, 18 are respectively mounted. In this case, the cutting mechanisms may be provided independently on the left and right sides, and each cutting mechanism can be independently moved up and down and held in the raised position. In that case, depending on the width of the remaining portion of the multi-seat S. It is possible to use the cutting mechanism on one side only for efficient planting work.

FIGS. 5 and 6 show another embodiment of the present invention, in which the tip of the arm 16 is provided with a freely rotatable large diameter idler roller 17-A for rolling the upper surface of the multi-sheet S. It is a bridge. The idler roller 17-A is provided with a plurality of cutting blades 18 in an arrangement similar to that of the embodiment of the present invention, and a pressing disk 17-B is mounted adjacent to the cutting blades 18 to cut the multi-sheet S. At the same time, both sides of the multi-sheet S cut by the pressing discs 17-B are pushed into the paddy field to widen the gap L between the cut portions to facilitate passage of the running wheels and the multi-seat support member. FIG. 8 shows a modified example of the one shown in FIGS. 5 and 6, in which a pressing disk 17-B is provided between the adjacent cutting blades 18 and 18, and the cut multi-sheet S is The central portion is pressed down by the disc 17-B and pushed into the field to widen the gap L between the cut portions as shown in FIG.
