BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a seedling table in a transplanting machine in which a seedling table is supported on a traveling machine so as to reciprocate left and right.

[0002]

2. Description of the Related Art In general, in a transplanting machine such as a multi-row rice transplanter, a seedling table that reciprocates right and left is provided at a rear portion of a traveling machine body, and a seedling sent from the seedling table onto an apron is planted. A planter that operates is scraped and planted in a field. Conventionally, in such a transplanter, a slide piece is provided on a support frame of the seedling mounting table so that the seedling mounting table can be reciprocated right and left, and a rail of the seedling mounting table is slid along the slide piece. Alternatively, a device provided with a guide roller instead of a slide piece is known.

[0003]

However, in the case where parts such as a slide piece and a guide roller are provided as described above, a seedling table having a wide seedling mounting area can be smoothly reciprocated right and left. Because of the necessity of support, the support structure for the fuselage becomes complicated and the maintainability of inspection, maintenance, etc. deteriorates.In addition, due to the increase in weight due to the large number of members constituting the support structure, the center of gravity of the fuselage is shifted As a result, not only the traveling balance of the transplanter becomes unstable, but also a high degree of adjustment technology is required for smooth reciprocation of the left and right, and depending on this adjustment work, play may be induced between the components. As a result, the support state of the seedling table becomes unstable, and as a result, when the seedlings sent out from the seedling table onto the apron are scraped by the planter, dripping of the floor soil occurs and the planting accuracy decreases, Had the disadvantage that The present invention was created in order to solve the above-mentioned drawbacks, and its purpose is to
In supporting the seedling table on the traveling machine, it is possible to simplify the support structure without providing slide pieces or guide rollers that may cause play, and to support the left and right reciprocating freely in a constantly stable state. An object of the present invention is to provide a support structure for a seedling mounting table in a transplanter that can improve planting accuracy.

[0004]

In order to solve the above-mentioned problems, the technical means adopted by the present invention is provided on a traveling body .
On apron, a lower end side of the seedling placing stand horizontally reciprocable supporting <br/> and comprising transplanter, the upper part of the back side of the seedling load platform, a predetermined interval a pair of moving brackets Exist,
A single series with support rods
And the both ends of the support rod
Part is supported on each moving bracket,
The is characterized in that to constitute a regulating member that only movably supported by the left-right direction.

[0005]

Therefore, according to the present invention, the seedling table supported by the traveling machine body is supported by an apron so that the lower end thereof can reciprocate right and left, and slides only in the left and right directions along a regulating body provided at an upper portion. Therefore, the seedling mounting table is supported in a stable state without play in the front-rear direction and the vertical direction, and smoothly reciprocates left and right.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 and 2, reference numeral 1 denotes a traveling machine of a walking rice transplanter exemplified as a transplanter, and a float 4 is provided below a machine frame 3 on which an engine unit 2 is mounted.
The left and right traveling wheels 6 supported by the chain case 5 are arranged on both sides. 7 is the engine unit 2
It is a hood that covers. The float 4 has a rear portion pivotally supported vertically via a connecting member 8 so as to be vertically swingable, and a front portion thereof which is vertically movable toward and away from the body frame 3. Case 5
The rotating shaft 1 whose base end protrudes from the transmission case 9
The pivot shaft 10 is pivotally supported on the outer circumference of the wheel 0 so that the power from the rotating shaft 10 is transmitted to the traveling wheels 6 by a chain transmission mechanism provided in the chain case 5. Numeral 11 denotes a hydraulic control mechanism composed of a hydraulic cylinder 12 and the like, which senses the vertical movement and rolling of the float 4 sliding on the rice field, and moves the left and right running wheels 6 simultaneously or vertically in opposite directions to form a body attitude. Is horizontally controlled. Reference numeral 13 denotes an operation handle that extends rearward and upward from the rear end of the body frame 3. On the front surface of the operation handle 13, a front / low / back / high height seedling mounting table 14 is provided with an apron 15 and a regulating body. The frame 16 is supported by the body frame 3 so as to be able to reciprocate right and left. 14a is the seedling mounting table 1
Numeral 4 is a seedling vertical feeding device, and 15a is a planter provided below the apron 15. It is.

As shown in FIGS. 3 and 4, the seedling mounting table 14 is supported at its lower end by an apron 15 and at its upper part by a regulating body 16 to be supported by the body frame 3 so as to be able to reciprocate left and right. Is configured. That is, at the lower end of the seedling mounting table 14, a fitting portion 18 is formed by bending the tip end side of a seedling stopper 17 provided orthogonal to the seedling mounting surface downward.
An apron 15 is fitted into the concave portion 18a of the fitting portion 18 to support the lower end side of the seedling mounting table 14 so as to be able to reciprocate left and right. Moving bracket 1 at a predetermined interval on the back of seedling mounting table 14
9 and 19 are provided. A cylinder 22 having a support rod 21 which can be moved in and out in the left-right direction is provided between both rising portions 20a and 20a of a fixed bracket 20 fixed to the body frame 3 side. A regulating body 16 that is movable only in the left-right direction is formed by pivotally supporting both ends of the rod 21 on moving brackets 19, 19.

In the above-described configuration, when performing the planting operation, the seedling table 14 supported by the traveling machine 1 reciprocates left and right with the running of the machine, and the apron 1
The planter 15a scrapes the seedlings sent out to 5 and plant them in the field. At this time, the seedling table 14 that reciprocates left and right
The lower end side of the fitting portion 18 is fitted into the apron 15 and the upper portion slides left and right while being supported by the regulating body 16 which is movable only in the left and right directions. Compared with the planter 15a, the support structure is simplified, and it is possible to support in a state in which the play is extremely small in both the front-rear direction and the up-down direction. Since it is suppressed by the apron 15 which inserts and supports the part 18, the seedlings can be scraped off with high accuracy by the planter 15a without causing dripping of the floor soil, etc., and a reliable planting operation can be performed.

Further, since the seedling table 14 is movably supported only in the left-right direction by the regulating body 16 in the upper part, the weight increase of each member constituting the support structure of the seedling table 14 is suppressed, and The center of gravity can be located on the lower side, and the running balance of the transplanter 1 can be improved. Furthermore,
In order to fix the seedling mounting table 14 to the body frame 3, after fitting the fitting portion 18 of the seedling mounting table 14 into the apron 15, the brackets 19, 19 and the bracket 20 on the body frame 3 side are set.
Need only be connected via the cylinder 22 having the support rod 21 inside, so that the mounting of the seedling mounting table 14 is easy, the parallelism of the seedling mounting table 14 with respect to the apron 15 can be easily obtained, and the lubrication points and the like can be improved. The maintenance work and the like can be easily performed with a small number.

[0010]
