Description

[Detailed description of the invention] The present invention relates to an attachment structure between a seedling stand and a horizontal feed shaft in a rice transplanter.

Conventionally, the connection between the seedling stand and the horizontal feed shaft was such that both ends of the horizontal feed shaft were fixed and supported by bolts, etc. on the mounting arms provided on the seedling stand. The load on the seedling stand due to vertical movement or horizontal shaking, or the load due to the weight of the seedling mat, is directly applied to the horizontal feed shaft, and forces such as bending, deflection, and twisting are applied to the horizontal feed shaft, and the support of the horizontal feed shaft is There was a risk that the seal part would be damaged and water, sludge, etc. would enter the cross-feeding case and cause trouble to the cross-feeding mechanism inside the case.

In this project, the engine is mounted on the front, and a seedling stand is installed on the rear.
In a rice transplanter that has a planting section at the bottom of the seedling stand,
The horizontal feed screw of the seedling stand is suspended horizontally on the machine frame, the horizontal feed shaft is attached to the sliding screw that is screwed into the horizontal feed screw, and both left and right ends of the horizontal feed shaft are formed as free ends. The supports with both left and right ends protruding from the rear surface of the seedling table are in contact with the inner surface of the board, and the horizontal feed shaft and the seedling table are provided separately, and the seedling table is configured to be interlocked with the horizontal feed shaft. By doing this, the seedling platform can be moved back and forth without applying the load on the seedling platform to the transverse feed shaft, and furthermore,
The holder is configured to allow horizontal adjustment of the relative position of the lateral feed shaft to the plate via an adjustment bolt inserted between the plate and the end of the lateral feed axis. To provide a rice transplanter which can adjust a seedling mounting stand so that the remaining seedlings at the terminal end have an even amount of seedlings, and can surely adjust the amount of seedlings taken.

To explain the embodiment shown in the drawings, A is the main body of the rice transplanter, in which an engine 2 is mounted on the front part of the machine base 1, and a seedling loading stand 3 with a low front and rear height is provided at the rear. The platform 3 has a seedling planting section 5 having planting claws 4 at the lower front thereof, and a running wheel 6 is provided at the center, and a center float 7 is provided at the bottom of the platform 1 and a seedling planting section 5 is provided on both sides of the center float 7. A side float 8.8 is provided.

9 is an operation bundle, and 10 is an auxiliary platform for seedling mats.

Reference numeral 11 denotes a transverse feed mechanism for the seedling table 3, and the machine frame 12.12

will be established.

In addition, the parts indicated by 17.17 in the figure are the cut ends of both ends of the above-mentioned transverse feed shaft, each shaped as a free end, and connected as a separate body to the receiving plate 18.18 provided on the back of the seedling stand 3. .

15', 15' are supporting seal parts of the lateral feed shaft 15, 19
．． 19 is an adjustment bolt provided on the cut end portion 17.17, 20.20 is a support portion provided on the back side of the seedling stand 3, 2
1.21 is a slide par that fits into the support part 20.20, 22 is a support rod that connects the slide par 21.21, and is supported on the machine frame 12° 12' via a mounting plate 23. be.

An upward arm 24 is removably connected to the upper end of the support rod 22, and a pin 25 is provided at the tip of the arm 24 to protrude upward from the support section 20. This makes it possible to reliably support the seedling stand 3 by preventing it from coming off.

Therefore, when reciprocating the seedling platform 3 in the lateral direction, the transverse screw punch 13 is rotated via the rotation mechanism 16, and the sliding screw punch 14 is reciprocated in accordance with the rotation. A lateral feed shaft 15 attached and supported by a sliding screw 14 is caused to reciprocate in the lateral direction.

And a receiving plate 18.1 that comes into contact with the cut end surface of the transverse feed shaft 15
8 is pressed by a transverse feed shaft 15, and the seedling platform 3 can be reciprocated in the transverse direction along the slide pars 21 and 21.

When a load is applied to the seedling platform 3 during the above-mentioned reciprocating operation, the load is absorbed by the seedling platform 3 itself,
The seedling table 3 is reliably moved back and forth without applying any load to a transverse feed shaft connected to the seedling table 3.

Therefore, according to the present invention, both cut end surfaces of the transverse feed shaft are formed as free ends, and the transverse feed shaft and the seedling stand are provided separately, so that the load applied to the seedling stand does not act on the transverse feed shaft and The feeding shaft can be prevented from bending, deflecting, twisting, etc., allowing the seedling platform to operate smoothly, and the inside of the transverse feeding case can be kept closed without any risk of damage to the supporting seal portion.

Furthermore, there is an effect that the assembly of the transverse feed mechanism can be simplified.

In addition, the receiver has an adjustment bolt interposed between the plate and the shaft end of the cross-feeding shaft, and the receiver can adjust the relative position of the cross-feeding shaft to the plate from side to side. The adjustment bolt can also eliminate dimensional errors between the seedlings, and furthermore, errors in picking up seedlings due to backlash in the transverse feed mechanism or partial defects in the mechanism at the end of the transverse feed of the seedling stand can cause the final remaining seedlings to be removed. Even if the amount of seedlings becomes too much or too little, the receiver can adjust the relative position of the horizontal feed shaft to the plate from side to side to adjust the seedling platform so that the amount of seedlings taken is even even at the end of the horizontal feed of the seedling platform. It has the effect of
