Here, FIG. 3 is a partial right side view of the vicinity of the rice transplanter planting device 100 of the embodiment of the present invention, and FIG. 4A is a seedling mounting guide rail 300 of the rice transplanter of the embodiment of the present invention. FIG. 4 (b) is a partial front view of the vicinity, FIG. 4 (b) is a partial plan view of the vicinity of the seedling loading platform guide rail 300 of the rice transplanter according to the embodiment of the present invention, and FIG. 4 (c) is the embodiment of the present invention. 5 (a) and 5 (b) are schematic right side views of a portion of the rice transplanter near the guide rail 300, and FIGS. 5 (a) and 5 (b) are schematic portions of the vicinity of the mounting rod handle 500 of the rice transplanter according to the embodiment of the present invention. It is an exploded perspective view (No. 1 and 2), and FIG. 6 is a schematic partial perspective view of the vicinity of the mounting rod handle 500 of the rice transplanter according to the embodiment of the present invention.

FIG. 4B shows both a state in which the mounting rod handle 500 is folded and a state in which the mounting rod handle 500 is not folded.

The seedling stand guide rail 300 has a seedling stand guide rail main body member 310 and a seedling stand guide rail end member 320, and the seedlings to be planted by the planting device 100 are placed and reciprocated in the left-right direction of the vehicle body. It is a rail that guides the 200.

The mounting rod 400 is a rod that connects and fixes the seedling mount guide rail end member 320 to the end of the seedling mount guide rail main body member 310.

The mounting rod handle 500 is a handle that turns the mounting rod 400 when the seedling mounting guide rail end member 320 is fixed to the end of the seedling mounting guide rail main body member 310.

The longitudinal direction of the mounting rod 400 is the left-right direction of the vehicle body.

The mounting rod handle 500 is a foldable handle mounted to the outer end of the mounting rod 400.

The mounting rod handle 500 also turns the mounting rod 400 when the seedling stand guide rail end member 320 is separated from or folded from the end of the seedling stand guide rail body member 310.

Even if the posture of the seedling stand guide rail 300 is switched from the use posture to the storage posture by such folding for reducing the lateral width of the vehicle body 10, the seedling stand 200 can be reciprocated. However, when moving from field to field or storing in a warehouse, if the seedling stand 200 is moved back and forth by an erroneous operation even though the posture of the seedling stand guide rail 300 is the storage posture, rice planting is performed. Since the machine may be damaged due to interference with the seedling mount guide rail 300, a configuration is adopted in which the left and right seedling mount guide rail end members 320 can be retracted to the front inside or the rear inside of the safer vehicle body 10. Will be done.

For example, in order to realize flexible rotation of the seedling stand guide rail end member 320 in the front-rear direction and the left-right direction, one end thereof is fixed to the seedling stand guide rail main body member 310 or the like inside the vehicle body 10. A slide hook 322, which is a member of the guide rail end member of the guide rail for the seedling mounting table having a curved shape, is used. The other end of the seedling stand guide rail end member slide hook 322 is an unsupported free end, and a hole or the like of the seedling stand guide rail end member 320 is hooked on the seedling stand guide rail end member slide hook 322 to hook the vehicle body 10 It is easy to slide the seedling cradle guide rail end member 320 inward along the seedling cradle guide rail end member slide hook 322 in three dimensions. The seedling mount guide rail is fixed to the vehicle body 10 by locking to a stay member, which is also called a storage position holding stay, so that the back surface faces the inside of the vehicle body 10. Almost no drop or loss of the end member 320 occurs.

The mounting rod handle 500 has a handle collar member 510 mounted to the outer end of the mounting rod 400 and a handle body member 520 foldably mounted to the handle collar member 510.

The folded handle body member 520 is not easily damaged due to interference with ridges in so-called ridge planting or the like.

The handle body member 520 has a horseshoe portion 521 rotatably attached to the handle collar member 510 at both ends, and a grip portion 522 attached to the horseshoe portion 521.

When the seedling stand guide rail end member 320 is fixed to the end of the seedling stand guide rail main body member 310, the horseshoe portion 521 is rotated with respect to the handle collar member 510, and the vehicle body is rotated from the outside of the vehicle body in the left-right direction of the vehicle body. After being fitted to the outer end of the mounting rod 400 in the inward direction, the mounting rod 400 is rotated by being rotated in a direction orthogonal to the left-right direction of the vehicle body by the force applied to the grip portion 522.

The handle collar member 510 is loosely fitted to the outer end of the mounting rod 400.

The seedling stand guide rail end member locking hook 321 engages the seedling stand guide rail end member 320 with the vehicle body 10 as described above when the seedling stand guide rail end member 320 is stored without being used. It is a hook to stop.

The mounting rod handle locking hook 501 is a hook for locking the mounting rod handle 500 with the seedling mounting guide rail end member 320 when the mounting rod handle 500 is stored without being used, and is a seedling mounting stand. It is integrally configured with the guide rail end member locking hook 321. Such a single-part specification not only makes the seedling stand guide rail configuration compact, but also reduces the number of parts.

The mounting rod handle pull-out prevention nut 504 is a nut located at the outermost position of the vehicle body of the mounting rod 400 to prevent the mounting rod handle 500 from coming off from the outer end of the mounting rod 400.

When the mounting rod handle 500 is used, the handle body member 520 is rotated around the mounting rod handle rotating pin 502 on the opposite side of the grip 522 with respect to the handle collar member 510 as a rotating stay. , It is firmly fitted to the substantially square and square mounting rod handle fitting nut 503 fixed to the outer end of the mounting rod 400.

As shown in FIGS. 7 (a) to 7 (c), the upper end of the horseshoe portion 521 that is fitted to the outer end of the mounting rod 400 may be (a) retracted or (b) popped out. It may be (c) smooth, but the mounting rod handle mating nut 503, which has a substantially polygonal horseshoe shape, is the first to facilitate smooth mating of the horseshoe portion 521. It is desirable that the part where it enters is spread outward.

Here, FIG. 7 (a) is a schematic explanatory view of the side surface shape of the horseshoe portion 521 of the rice transplanter according to the embodiment of the present invention, and FIGS. 7 (b) and 7 (c) are modified examples in the present invention. It is a schematic explanatory view (No. 1 and 2) of the side surface shape of the horseshoe portion 521 of the rice transplanter of the embodiment.

As shown in FIGS. 8 (a) to 8 (d), not only the mounting rod handle 500 in the usage posture does not interfere with the seedling stand 200, but also the width of the planting device 100 does not increase. ..

Here, FIGS. 8 (a) to 8 (d) are partial right side views (Nos. 1 to 4) of the vicinity of the mounting rod handle 500 of the rice transplanter according to the embodiment of the present invention.

That is, after the mounting rod tightening work or the mounting rod loosening work in which the mounting rod 400 is rotated by the mounting rod handle 500 is completed, the mounting rod handle is removed from the mounting nut 503 and around the mounting rod handle rotating pin 502. The rotated handle body member 520 is raised with respect to the handle collar member 510. The posture of the mounting rod handle 500 is switched from the usage posture to the storage posture by tilting the handle body member 520 rotated around the mounting rod 400 together with the handle collar member 510 with respect to the handle collar member 510. ..

As shown in FIGS. 9 (a) and 9 (b), the outermost position of the mounting rod handle 500 locked by the mounting rod handle locking hook 501 is the mounting of the guard member 301, which is also called the front plate guard. Compared to the outermost position of the vehicle body of the seedling stand 200 which is reciprocated in the left-right direction, which is the position, the mounting rod handle 500 does not protrude to the outside, and the mounting rod handle 500 does not overlap with the seedling mount 200 in the side view.

Here, FIG. 9A is a partial plan view of the vicinity of the seedling loading platform guide rail 300 of the rice transplanter of the embodiment of the present invention, and FIG. 9B is fertilization of the rice transplanter of the embodiment of the present invention. It is a partial right side view in the vicinity of the apparatus 70.

FIG. 9A shows both a state in which the mounting rod handle 500 is folded and a state in which the mounting rod handle 500 is not folded.

Of course, even if the posture of the seedling mount guide rail 300 is switched from the use posture to the storage posture as described above, the innermost position of the vehicle body of the mounting rod handle 500 is compared with the innermost position of the vehicle body of the seedling mount guide rail 300. The mounting rod handle 500 does not overlap with the hose member 71 of the fertilizer application device 70, which is also called a fertilizer application hose in the side view.

Next, the configuration and operation of the rice transplanter according to the present embodiment will be described more specifically with reference to FIGS. 10 to 14.

Here, FIGS. 10 to 12 are partial perspective views (Nos. 1 to 3) of the vicinity of the rice transplanter operating unit 50 of the embodiment of the present invention, and FIG. 13 is an operating unit of the rice transplanter of the embodiment of the present invention. It is a partial left side view of the vicinity of 50, and FIG. 14 is a partial plan view of the vicinity of the operation unit 50 of the rice transplanter according to the embodiment of the present invention.

The engine cover trisection specification in which the engine cover 600 is divided into the front partial cover 610, the center partial cover 620 and the rear partial cover 630 is adopted instead of the engine cover box shape specification. Therefore, of the front partial cover 610, the center partial cover 620, and the rear partial cover 630, only the partial cover that is required to be removed can be easily removed, and the maintenance work can be easily performed without removing the seat 51 itself provided above. Can be done.

As will be described later, the front partial cover 610, the center partial cover 620 and the rear partial cover 630 are not only firmly mounted without the rear partial cover 630 being lifted, but also the screws and tools are partially covered. Not required for installation and removal.

The front partial cover 610 is a hood-shaped cover formed by using resin, and is rotatable around the front partial cover rotation pin 613 provided on the seat support frame 601 or the like. When the front partial cover 610 is closed, the substantially U-shaped front partial cover front hook 611 located on the lower side is locked to the seat support frame 601 or the like and does not interfere with the rear partial cover front hook 631. The substantially J-shaped bent front portion cover rear hook 612 located on the upper side, which is arranged so as to be offset in the left-right direction of the vehicle body, is locked to the front portion cover rotation pin 613.

The center partial cover 620 is a plate-shaped cover formed by using a metal such as iron that covers the engine 20 from above, and is slidable in the front-rear direction of the vehicle body.

The rear partial cover 630 is a hood-shaped cover formed by using resin and is removable. When the rear partial cover 630 is attached, the front hook 631 of the rear partial cover is bent in a substantially J shape and is arranged so as to be offset in the left-right direction of the vehicle body so as not to interfere with the hook 612 after the front partial cover. Is locked to the front partial cover rotation pin 613 by passing over the front partial cover rotation pin 613 from above, and the substantially U-shaped rear partial cover rear hook 632 is locked to the seat support frame 601 or the like. ..

In the work of removing the partial cover, the rear partial cover 630 is first removed by unlocking the front hook 631 of the rear partial cover, and the front partial cover 610 is unlocked by the hook 612 after the front partial cover. Then, if necessary, the center partial cover 620 is slid forward.

The front partial cover rotation pin 613 is not only used as a rotating member, a locking member of the front partial cover rear hook 612, and a locking member of the rear partial cover front hook 631, but also has a bent shape of the rear partial cover front hook 631. In cooperation with the above, it also functions as a stopper member for preventing the attached rear partial cover 630 from shifting forward, so that the number of parts can be reduced and the cost can be reduced.

The drink container holder 650 is a recess provided by utilizing the upper left surface of the rear partial cover 630 or the like.

The accessory case 660 is a recess provided on the front side of the drink container holder 650 in the front-rear direction of the vehicle body by utilizing the upper left surface of the rear partial cover 630.

The drink container holder 650 is farther from the engine 20 than the accessory case 660, and the drink container housed in the drink container holder 650 is less susceptible to the heat of the engine 20.

The main floor 700 such as the step floor is not provided below the accessory case 660, but is provided below the drink container holder 650. Since the two-layer heat insulating structure is formed by the main floor 700 and the drink container holder 650, the drink container housed in the drink container holder 650 is further less affected by the heat of the engine 20.

The upper end edge 652 of the drink container holder protrudes upward so that the side wall of the drink container holder 650 is considerably longer in the vertical direction than the side wall of the accessory case 660, and the PET bottle stored in the drink container holder 650 Drink containers like this are hard to fall over.

The side wall between the drink container holder 650 and the accessory case 660 is cut out in a substantially U shape, and the accessory case 660 is connected to the drink container holder 650, so that it is long if the drink container holder 650 is empty. A small accessory can be stored in the accessory container 660.

The bottom of the drink container holder 650 is inclined toward the center where the drink container holder drain hole 651 is drilled.

Since the bottom of the drink container holder 650 is lower than the bottom of the accessory case 660 and the side closer to the drink container holder 650 is lower, the drink container holder 650 and the accessory case 660 are filled with muddy water. All the drinks are discharged from the holder drain hole 651 to the main floor 700 below the drink container holder 650. Not only is the main floor inclined surface that lowers the outside of the vehicle body 10 formed so that the discharged muddy water does not enter the engine 20, but also the main floor rising edge 701 is erected on the side of the engine 20. There is. Therefore, there is almost no possibility that rust or the like due to muddy water will occur on the engine 20 and the air cleaner covered by the engine cover 600.

The transplanting machine in the present invention can reduce damage to the mounting rod handle due to interference with ridges and the like, and is useful for a purpose of being used for a transplanting machine such as a rice transplanter.
