BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bumper mounting structure for protecting a rear portion of a planted chain case disposed in a planting portion of a rice transplanter.

[0002]

2. Description of the Related Art Conventionally, in a planting section of a rice transplanter, there are a plurality of planting chain cases, which are driven by a planting drive unit through a chain to drive a planting claw, in a longitudinal direction. They are arranged in parallel. The planting claw is pivotally supported at the rear portion of the planting chain case and is provided on a planting arm that is rotationally driven. Also, below the planted chain case,
A float is arranged for the purpose of facilitating the traveling of the planting part on the field, and in the case of 5 or 6 row type, a center float is arranged in the center and side floats are arranged on the left and right sides. The thing is mainly. Since the center float has a long front-rear length, the rear part of the side float is also made longer in order to mitigate the shock of foreign matter interference on the rear part of the center float, and by this, it is pivotally supported by the planted chain case and the rear part thereof. It protected the planting arm.

[0003]

However, the longer the front and rear length of the float, the higher the tendency of mud pushing, and the larger the suspension mechanism of the float, which leads to higher cost. Further, since the float itself is a soft member, it may be damaged due to foreign matter interference. For these reasons, even if the side float was shortened, there was no other member for protecting the planted chain case, the planted arm, and the rear part of the center float. Furthermore, at the start of rice planting work, when it is on the ridge, when the planting part is lowered, it may be caught on the ridge from below the planting chain case or the planting arm, and these members may be damaged, There was no structure to protect these members from below.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the structure of the present invention will be described based on the embodiments shown in the accompanying drawings. Fig. 1 is an overall side view of a rice transplanter equipped with a fertilizer applicator and a chemical sprayer, Fig. 2 is a side view of a planted chain case with a rear bumper attached, Fig. 3 is a plan view of the same, and Fig. 4 is a front view of the rear bumper. 5, FIG. 5 is the same rear view, FIG. 6 is a plan view of a float in which a fertilizer grooving device and a chemical spray grooving device are arranged, and FIG. 7 shows an attachment structure of an auxiliary marker in a side bumper of a planting part. FIG. 8 is a perspective view, and FIG. 8 is a side view showing a mode of auxiliary marker switching corresponding to the marker confirmation position.

The overall structure of the rice transplanter will be described with reference to FIG. In the traveling vehicle body A, the power of the engine E is transmitted to the mission case M1 to drive the front wheels FW and the rear wheels RW, and the PTO shaft 11 is projected from the mission case M1. At the rear part of the traveling vehicle body A, an elevating link L which is vertically rotated by hydraulic pressure or the like is provided so as to project, and the planting part B is connected so as to be vertically movable. In the planting part B, a planting mission case M2 is arranged in the center of the lower front part, and is transmitted to the input shaft of the planting mission case M2 from the PTO shaft 11 via a universal joint 12. The lateral feeding drive of the seedling placing table 7 and the vertical feed belt 8.8 in the seedling placing table 7
.. Drives transport of. Further, through a plurality of planting chain cases 4 protruding rearward, a planting arm 5 arranged at the rear end thereof is rotationally driven, and planting claws arranged at both ends of the planting arm 5. The seedlings are taken from the seedling stand 7 by driving 6/6 and planted in the field. In addition, planting section B
A center float 9 is hung in the center and side floats 10 are hung so that the side floats 10 can be moved to the left and right.

Further, in the rice transplanter of this embodiment, a fertilizer application device C such as a fertilizer hopper 13 is mounted on the rear part of the traveling vehicle A, and a chemical hopper 16 or the like is installed on the rear part of the planting chain case 4 of the planting part B. The medicine dispersal device D is mounted, and a driving force for supplying the medicine is obtained from the power take-out shaft 25 at the rear part of the planted chain case 4 shown in FIG. From the fertilizer application device C, a fertilizer application hose 14 is extended to the planting part B side, and fertilizer application groover 15 at the tip of the fertilizer application hose 14 is arranged on both sides of each float 9 and 10, while spraying chemicals. A drug hose 17 is also extended from the device D, and a drug spraying grooving device 18 at the tip thereof is disposed adjacent to the fertilizer applying grooving device 15 on both sides of the floats 9 and 10. That is, the lateral fertilization and the lateral chemical spraying can be performed simultaneously with the transplanting of the seedlings.

Conventionally, the spraying of chemicals such as herbicides has been carried out in a step different from the step of transplanting seedlings. For example, spraying with a chemical sprayer at the time of transplantation, or growth to some extent after transplanting. I used a method such as spraying with a boom sprayer. However, since it is a separate process, the work is not only doubled, but in the former case, it is evenly sprayed on the soil, which poses an environmental problem. There is a risk that Therefore, while the side-row fertilizer applicator C is mounted on the traveling vehicle body A side as described above,
The drug spraying device D is mounted on the planting part B side so that the drug can be sprayed at the same time as the transplantation so that the spraying work in a separate process is not necessary and the spraying amount is minimized because the spraying is performed on the side strip. , It has an environmental protection effect by local spraying and is safe without being sprayed directly on crops. On the contrary, the chemical spraying device D is provided on the traveling vehicle A side, and the fertilizer application device C is provided on the planting part B side.
May be mounted. In addition, by coating the drug with a water-soluble film, the transplanted seedlings can take effect after they have survived, eliminating the fear of damaging the seedlings.
Further, as shown in FIG. 6, the fertilizer application grooving device 15 is disposed on the both sides of the side float 10 (similarly to the center float 9) in the immediate vicinity of the planting strip P. 1
8 is further arranged on the outer side thereof and is distant from the planting strip P, thereby reducing the chemical damage to the seedlings.

Next, the bumper 1 attached to the rear portion of the planted chain case 4 will be described. First, referring to from Fig. 2 and 3 previously internal configuration of the planting chain case 4 are sprockets attached to the front drive shaft 22 which is the transmission from the planting transmission case M2, with the rear of the planting drive shaft The chain 23 is wound around the sprocket provided with 24, the planting drive shaft 24 is driven, and the planting arms 5 mounted on both sides are rotationally driven with this as the center of rotation.
Furthermore, the gearing inside the planting arm 5 allows the planting claws 6 and 6 to maintain the planting posture, and the rotation speed of the planting arm 5 itself is adjusted.

In this way, a bumper mounting stay 3 is fixedly installed at the rear lower end of each planted chain case 4 arranged in the planting portion B as shown in FIGS. 2 and 3, and the bumper mounting stay 3 is fixed.
The rear bumper 1 is attached via. Bumper 1
2 to FIG. 5, a member made of synthetic resin or the like is hollowed to form a cushioning material, and a central portion thereof serves as a flat plate portion 1a, and a rear portion of the bumper mounting stay 3 is provided at a front side thereof. A pair of left and right reflecting mirrors 2 and 2 are brought into contact with the rear side, and they are fastened together by bolt holes 1b and 1b, respectively. In this way, since the reflecting mirrors 2 are attached to the rear surface as shown in FIG. 5, the safety during nighttime driving is improved.

The mounting shape of the bumper 1 will be described.
Since the bumper attaching stay 3 is attached below the rear end of the planted chain case 4 as described above, the lower portion of the bumper 1 also extends below the lower end of the planted chain case 4, and accordingly, The planted chain case 4 and the planted arm 5 pivotally supported by this can be protected from below.
Further, the lower end shape of the bumper mounting stay 3 is continuously drawn from the lower end of the planted chain case 4 in a side view as shown in FIG. 2, and its rear end extension line is a tangent line to the lower end of the bumper 1. There is. That is, from the lower end of the planted chain case 4 to the lower end of the bumper 1 is continuous in side view, and there is no projecting part or extremely recessed part in the middle, so these lower end parts are ridges or the like. Even when it is placed on the upper part of the plant, there is no place where it is caught by the ridge or the like, or there is no place where the soil such as the ridge falls into, so that the planted chain case 4 and the like can be moved smoothly from the place where it is placed.

Further, the bumper 1 attached to the rear portion of the planted chain case 4 covers the planted arms 5, 5 pivotally supported on both sides of the planted chain case 4, but the lateral width is supported by the left and right planting arms 5. Since the bumper 1 is arranged narrower than the space between the planting claws 6 and 6 supporting positions, that is, inside the planting strip, the planting chain case 4 and the planting chain case 4 do not interfere with the planting claws. The arm 5 can be protected from the rear,
Since the rear part of the center float 9 can also be protected, it is not necessary to extend the rear part of the side float to protect the center float as in the conventional case, and the short side float 10 can be suspended as shown in FIG. is there.

A side bumper 2 for protecting the side of the planting section B
0 and the auxiliary marker 21 will be described. As shown in FIG. 1, a pair of left and right side frames 19 are provided below the lower surface of the seedling placing table 7 to support the seedling placing table 7. As shown in FIG.・
A supporting plate 19a for rotatably supporting the rotating shaft 26 of 10 is extended, and the shaft portion 20a of the side bumper 20 is rotatably fitted into the boss portion 19b of the supporting plate 19a. The side bumper 20 extends outward in a substantially horizontal shape.
The side bumper 20 not only protects the planting part B from the side interference, but also pivots downward to make it vertical as shown by the broken line in FIG. It becomes the B stand.

Further, the auxiliary marker 21 is a member for indicating the side position of the machine body, and is attached to the upper part of the front wheel FW to confirm the side part of the traveling vehicle A or to confirm the side part of the planting part B. Although it is attached to the side bumper 20,
Conventionally, it was fixedly attached. When the fertilizer application device C is mounted on the rear portion of the traveling vehicle body A as in the present embodiment, when the marker is attached vertically, for example, when the marker is attached to the side bumper 20, the back of the back bumper 20 is fixed. In the case of the state of X in FIG. 8 where the marker is confirmed before the fertilizer application device C because of low or the like, the marker disappears because of the fertilizer application device C. On the contrary, when the marker is tilted horizontally forward, the marker cannot be seen in the Y state in FIG. 8 seen from the rear part of the fertilizer application device C because of the fact that the marker is tall this time. Therefore, as shown in FIG. 7, the base end portion 21a of the auxiliary marker 21 can be switched to both states.
Is rotatably mounted on a shaft member forming the side bumper 20 and is locked by a locking pin 21b so that it can be switched between an upright position and a horizontal position. As shown in FIG. C
Auxiliary marker 21 when viewed from the front (X state)
Is tilted to the front so as to be horizontal, and when viewed from behind the fertilizer application device C (Y state), it is made vertical.

[0017]

The present invention having the above-described structure has the following effects. That is, since the rear bumper is attached to the rear part of the planting chain case of the rice transplanter as claimed in claim 1, the planting chain case and the planting arm are protected from the rear side, and the center float rear part is further protected. Therefore, it is not necessary to lengthen the front and rear sides of the side float, and a short side and low cost side float can be attached. On the other hand, by making the width narrower than between the planting patterns, it does not interfere with the planting claws and does not catch the planting seedlings.

Further, as in claim 2, by attaching the stay below the lower end of the planted chain case, the rear portion of the bumper extends below the planted chain case, and the planted chain case and the planted arm are The lower ends of these are protected without directly contacting the field or the like.
