Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter in which the device can be driven and moved laterally for planting.

For example, when planting along a ridge, this type of rice transplanter runs on flat ground a little away from the ridge to prevent the machine from tilting from side to side. By moving laterally to the ridge side, it can be used to plant right up to the edge of the ridge.Also, reciprocating planting can be used to easily accompany the aircraft with a relatively large turning radius when turning in the middle of work, while still being able to plant. The planting process can be carried out advantageously by moving the device laterally to maintain a constant row spacing between the already planted seedlings and the next planting. With rice transplanters, when planting, the device was moved laterally while being held in the planting position, which caused the inconvenience that a large amount of mud was pushed sideways by the lateral movement of the float, which had a negative impact on the already planted seedlings. there were.

In view of the above-mentioned circumstances, the present invention has been developed in such a way that it not only avoids mud being pushed sideways by the float when the device is moved laterally, but also allows for easy operation. The purpose is to do this, and in the official document, the planting is carried out by the initial activation of the operating lever for the lateral movement drive mechanism of the device.
Planting is characterized by the provision of a device that lifts the entire device or only the float away from the mud surface.

As a result, when the planting device is moved horizontally depending on the work content, the planting device is moved horizontally after or while raising the entire device or only the float away from the mud surface. Therefore, as described above, a large amount of mud is not pushed out laterally by the float, and it is possible to avoid adverse effects on the already planted seedlings caused by this extruded mud.

Furthermore, planting for this purpose can be easily and accurately carried out by sequentially operating a single lever to move the device horizontally and raise it above the ground.

Embodiments of the present invention will be described below based on the drawings.

Fig. 1 Demonstration of a ride-on rice transplanter of the spring mount type during waist training 1
This machine has a pair of left and right running wheels 2 and 3 arranged at its front and rear positions, and 4 is a seedling stand 5 that can be reciprocated in the left and right directions, a claw for planting, and a drive mechanism for these. This is a planting device that consists of a mission case 7 and a float 8 for leveling the planting surface. In addition, the planting device is configured to be able to be driven and moved in the lateral direction, and the planting is performed by the initial activation of the operating lever 10 for the lateral movement drive mechanism main of the device 4. A device 11 is provided to raise the entire body a minute distance from the mud surface.

The driving mechanism U for raising and lowering the planting device is constructed as follows.

That is, the planting transmission case 7 of the planting device 4 is pivotally connected to the rear hitch 13 of the main unit 1 via a pair of left and right upper links 14 and lower links 15 so as to be able to move up and down. Hydraulic cylinder 1 installed on machine 1 side
The pair of left and right lift arms 17 and the lower link 15 are connected to the lift rod 1 and are driven and oscillated in the vertical direction by the lift rod 1
8, and thus the lift arm 11
The planting device is configured to be driven up and down via the upper link 14 and lower link 15 by vertical swinging of the.

The lateral movement drive mechanism 9 of the planting device 4 is constructed as follows, as shown in FIGS. 2 to 4.

That is, the planting is carried out on the supporting member 19 which is pivotally connected to the rear end portions of the upper link 14 and the lower link 15, and the planting is carried out inside the guide rail 20, which is connected to the front surface of the transmission case 7 and has a C-shaped cross section. Four transferable rollers 21 are provided, and among the swing support arms 22 of the rollers 21, swing support arms 22, 22 and 2 that face each other in the left and right lateral directions are provided.
A spring 23 is interposed between the support member 19 and the guide rail 20 to bias the roller 21 in the direction of contacting the guide rail 20.
A hydraulic cylinder 24 is provided between the planter and the planter to drive and move the entire planting device in the left and right directions.

The device is constructed as follows.

That is, as shown in FIG. 5, in the control section of the main machine 1,
The operation lever 1o of the valve 25 relative to the hydraulic cylinder 24 of the lateral movement drive mechanism 9 is pivotably pivoted from the neutral position N to the left movement operation position and the right movement operation position R. 25 is connected to the operating shaft 25A through a pin 26 and a long hole 27, and the operating lever 10 and the hydraulic cylinder 16 of the lifting drive mechanism 12
The control lever 1 is connected to a valve (not shown) via the operating wire 28, and as shown in FIG.
In conjunction with the initial entry operation to the left movement operation position R or the right movement operation position R of 0, the entire planting device 4 is lifted a minute distance from the mud surface via the lifting drive mechanism 12, and In conjunction with the return operation of the operating lever 10 to the neutral position N, the planting device 4 is configured to be lowered to the planting operating position.

In the above-mentioned embodiment, the planting is performed in conjunction with the initial activation of the control lever 10 for the lateral movement drive mechanism 9 of the device 4, so that the entire device 4 is lifted away from the mud surface. Alternatively, only the float 8 may be raised away from the mud surface, or the planting may be performed by moving the equipment laterally while raising it.
