JPH037504A - Traversing unit for seedling platform in rice transplanter - Google Patents

Abstract

PURPOSE:To make the transmission mechanism compact on the lead metal side and enable the lead cam shaft to be changed in the traverse speed easily by driving the lead metal through a transmission mechanism from the driving shaft for driving the transplanter unit. CONSTITUTION:The transplanter is transmitted by the rotation of the driving shaft 4, and simultaneously lead metal 9 is rotated as it is properly changed in speed with the transmission mechanism A. The lead cam shaft 8 is traversed with the nail 10 of the lead metal 9 and the seedling platform 15 is transversely reciprocated with the extended shafts 8a and 8b connected to the lead cam shaft 8. Consequently, the seedlings on the platform 15 are divided with the rear transplanter fitted to the transplanter-driving shaft 2 and transplanted to the rice paddy, and the division can be controlled by means of the speed change mechanism A. The mechanism can be made compact and light in weight.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a device for moving a seedling stand in a rice transplanter from side to side.

Conventional technology Conventionally, in a rice transplanter, a device for moving the seedling stand left and right has been designed to move the lead cam shaft horizontally and reciprocally by rotating a lead metal equipped with a lead claw that engages with the lead groove of the lead cam shaft. Some had seedling stands attached to them.

However, the transmission on the lead metal side was such that the lead metal was directly rotated from the yK motive side.

Problems to be Solved by the Invention In the prior art, since input from the prime mover side is taken into the lead metal side, the lead metal portion becomes large and a compact structure cannot be achieved.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention inputs power to the drive shaft 4 that drives the seedling transplanter, and the drive shaft 4 and the
The rotation of the lead metal 9 is connected to the lead metal 9 provided with a lead pawl 10 that engages with the lead groove of a lead camshaft 8 rotatably mounted parallel to the drive shaft 4 via a switching mechanism A. is provided so as to be changeable, the speed of horizontal lateral movement v of a lead cam shaft 8 is changeable, and a seedling support stand 15 is attached to the lead cam shaft 8 to provide a left-right movement device for a seedling stand in a rice transplanter.

Functions and Effects of the Invention According to this invention, the lead metal is transmitted and rotated from the drive shaft that drives the seedling transplanter side, which is manually powered from the original ω1 machine side, via the transmission mechanism, so that the rotation transmission mechanism on the lead metal side is is made more compact, and the left/right ω1 speed of the lead cam shaft that operates the seedling stand can be easily changed, making it easy to adjust the amount of seedling division.

Example 1 is a transmission case that also serves as a part of the rice transplanter frame.

Transplanting transmission cases 3a, 3b, and 3c are attached to the transmission case 1 on both the left and right sides and in the middle part of the left and right, and each of the transmission cases 3a, 3b, and 3c has a transplanting transmission shaft 2 that transmits and rotates the seedling transplanting tool. One of the protruding parts bulges out thickly so that the transmission mechanism A can be housed inside, and can be separated at this part.

Reference numeral 4 denotes a drive shaft, which is rotatably mounted on the left and right long parts of the transmission case 1, and both ends thereof are connected to the transplanted transmission case 3.
It is extended to the outside through a and 3b. 5 is an input shaft, which is transmitted from the prime mover side, and is connected to a set of bevel gears 6.
The drive @4 is configured to be transmitted and rotated from the input shaft 5 via the input shaft 7.

8 is a lead cam shaft, which is a bulge part (a) of the transmission case 1.
It is mounted on an axis so that it can move left and right.

Further, on both sides of this lead cam shaft 8, there are extensions and till
l 8g and 8b are fixed.

A lead metal 9 has a lead claw 1o that engages with the lead groove of the lead cam @8, and is fitted onto the lead cam shaft 8 and rotatably mounted on the transmission case 1. As described above, a transmission mechanism A is interposed between the drive shaft 4 and the lead metal 9, and includes a gear 11.12 and a gear 13.14 that can be selectively engaged with the gear 11.12.

Reference numeral 15 denotes a seedling stand of the rice transplanter, which is attached to both ends of the extension shafts 8a and 8b.

16.17 is a seedling vertical feeding device B installed on the bottom of the seedling stand 15
This is a drive arm that is driven when the seedling table 15 moves to the lateral end.

Reference numerals 18 and 19 are elastic bellows made of rubber and serve as a mud and water barrier for the lead cam shaft.

Reference numeral 20 denotes a sprocket equipped with a clutch mechanism, and a chino 22 is wound between the sprocket 21 on the transplanted drive shaft 2 side and the transplanted drive shaft 2 is transmitted.

In addition, FIG. 3 shows another example, and in this example, the seedling stand 15
A gear 24 meshing with the gear 14 of the transmission mechanism A transmits power to a rotary shaft 23 to which a drive arm 16a * 17a is attached, which drives a vertical seedling feeding device provided on the bottom of the seedling table 15 when it moves to the horizontal end. It is configured as follows.

According to the above configuration, the rotation of the drive shaft 4 transmits power to the implant side, and at the same time, the lead metal 9 is rotated while being appropriately changed in speed by the transmission mechanism A.
The lead cam @8 is moved left and right by the claw 10.

Therefore, an extension shaft 8a connected to this lead cam shaft 8,
At 8b, the seedling platform 15 is moved horizontally and reciprocally. Therefore, the seedlings placed on the seedling platform 15 are divided by the transplant tool attached to the transplant drive shaft 2 and transplanted to the field, and the amount of division can be adjusted by the transmission mechanism A.

In this transmission mechanism, the transmission case 1 itself can be made compact and lightweight.
