Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a seedling planting section provided in a transplanting machine such as a rice transplanting machine and an upland transplanting machine.

[0002]

2. Description of the Related Art Generally, in transplanting machines such as rice transplanters and upland crop transplanters, a seedling mounting table that reciprocates in the machine width direction is provided at a rear portion of a traveling machine, and a plurality of seedlings sent from the seedling mounting table are provided. The seedling planting section is configured to scrape with the planting claw and plant it in the field.

[0003] However, in the above-described seedling planting section, in addition to the provision of the seedling stand and the plurality of planting rods, a feed mechanism for reciprocating the seedling stand, and an operation of sensing a float sliding in a field scene. Since there are complicated components such as a horizontal control mechanism of the planting part using the, the structure is inevitably twisted in the assembled state of the mechanism and the mechanism or the member and the member, and the rattling occurs and the planting accuracy decreases. In addition to the above, the PTO input case that supplies the driving force from the traveling body to the above-described components is required to transmit a large amount of driving force. Therefore, if the supporting structure is made strong for each component,
On the other hand, the weight of the entire seedling planting section is increased and the airframe balance is lost, leaving room for improvement.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned situation, and an object of the present invention is to fix a seedling planting portion of a transplanting machine to a support frame and a fixing frame. By fixing the case upper surface of each of the planter transmission cases described above with a horizontal connecting member, the PT can be supported by a strong frame structure and has a necessary and sufficient rigidity.
An object of the present invention is to provide a transplanter that can secure the mounting state of the O input case and can be configured as a seedling planting section without deformation or twisting without increasing the overall weight.

[0005]

The technical means adopted by the present invention for solving the problems is that a plurality of planter transmission cases are mounted on a support frame extending in the machine body width direction at predetermined intervals toward the rear of the machine body. And an apron support plate of an apron that reciprocates and supports the lower part of the seedling mounting table between the case upper surfaces of the respective planter transmission cases and transmits a driving force to the respective planter transmission cases. The PTO input case is attached and fixed to the support frame and the apron support plate between the support frame and the apron support plate located on the rear side.

Is a float provided below each planter transmission case 5.

A PTO input case 9 for transmitting rotational power to each of the planter transmission cases 5, 5,... Is fixed to the lower surface of the support frame 4, and the planter transmission case 5, 5,. The drive shafts 10 extending in the left-right direction through the mounting base end side of the... Are interlocked and connected while being housed in the case pipe 10a, and the upper surfaces of the respective case of the planter transmission cases 5, 5,. As shown in FIG. 4, a support block 1 having an inclined support surface 11a is provided.
1 are integrally formed.

An apron support plate 12 having a U-shape in side view is fixed between the inclined support surfaces 11a, 11a of the support blocks 11, 11... An apron 13 fixed to the support 6 supports a slide body 14 provided on the back side of the lower portion 6a of the seedling mounting table 6 so that the seedling mounting table 6 can reciprocate.

As shown in FIG. 5 (a), each float 8, 8...
A support pipe 16 forming a support base end of a float adjusting arm 15 for suspending... Extends and fixed between the respective planter transmission cases 5, 5,..., And the PTO input case 9 is shown in FIG. As described above, the front side of the main body case 9a is screwed to the lower surface of the support frame 4 via the mounting seat 9b,
The rear end of the main body case 9a is screwed via a fixed plate 9c to an apron support plate 12 extending between the upper surfaces of the planter transmission cases 5, 5,. Reference numeral 17 denotes a coil spring that suspends the front end side of the float 8, and reference numeral 18 denotes a buffer spring formed of a leaf spring that prevents abutment with the lower surface of the planter transmission case 5 when the float 8 moves up and down.

Since the present invention is configured as described above,
When performing seedling planting work in the field, the operation of the seedling planting unit 7 accompanying the movement of the traveling machine 1 causes the planting rods 5a, 5a,. Thus, the seedlings on the seedling table 6 which reciprocate in the horizontal direction are scraped, and the seedling planting operation in the field scene is performed.

Here, the seedling table 6 reciprocates as described above.
As shown in FIG. 5 (b), black spots are formed by the support frame 4, the planter transmission cases 5, 5,... Attached and fixed thereto, and the apron support plate 12 of the apron 13 fixed between the support blocks 11. Since the frame is configured with the fixing structure shown, without particularly increasing the overall weight,
The rigid frame structure can be obtained by the cooperation of the rigidities of the respective constituent members, and the respective planter transmission cases 5, 5
Since the PTO input case 9 for transmitting the driving force to the... Is fixed between the support frame 4 and the apron support plate 12, which have a strong frame structure as described above, the PTO input case 9 has a necessary and sufficient rigidity. In this state, the PTO input case 9 can be arranged. The support pipes 16 used for mounting the floats 8, 8,...
Since it is incorporated as a part of the support frame body, a more robust frame structure can be obtained.

[0012]

According to the present invention, a plurality of planter transmission cases are provided at predetermined intervals toward the rear of the fuselage on a support frame extending in the width direction of the fuselage, and the lower part of the seedling mounting table is reciprocated. The apron support plate of the apron to be freely supported is fixed between the case upper surfaces of the respective planter transmission cases, and the PTO input case for transmitting the driving force to the respective planter transmission cases is provided on the support frame and the rear side thereof. Since the support frame and the apron support plate are attached and fixed between the apron support plate located therein, the seedling placement structure of the transplanter is firmly secured using the support frame, each planter transmission case and the apron support plate. A PTO input case that can be incorporated in a simple frame structure and transmits driving force to each planter transmission case,
It is possible to effectively use the limited space in the above-mentioned frame body that maintains the rigidity and to firmly mount the frame, thereby preventing the occurrence of distortion, deformation, etc. of each mechanism of the seedling planting part. .
