Description

[Detailed description of the invention] The present invention relates to a leveling device for a riding rice transplanter.

That is, a leveling plate for erasing wheel marks is attached to the rear hit part of a riding rice transplanter, and the leveling plate is configured to be able to move up and down in conjunction with the lifting and lowering operations of the seedling planting device. This prevents the leveling plate used for the machine from bending due to sticking into the field when the machine backs up or turns, or the horizontal bar to which the leveling plate is attached does not bend.

The embodiments shown in the drawings will be described below.

The one shown is a riding rice transplanter,
1, the brackets 4 and 4' projecting above and below the rear end of the front body 2 and the brackets 5 and 5' projecting above and below the front end of the rear body 3 are pivoted with pins on the same vertical line, respectively, so that the horizontal direction can be adjusted. It shows a bendable steering body, and on both the left and right sides of both the front and rear bodies 2 and 3, an engine 6 mounted on the rear body 3 is connected via bendable shafts 7 and 8 mounted between the two bodies. Wheels 9, 9 and 10, 10 to which power is transmitted are mounted so as to be movable up and down by swing arms 11, 11, 12, 12.
By rotating a handle 15 in front of a seat 14 mounted on the vehicle body 3, the direction and degree of bending of both bodies 2 and 3 can be adjusted to allow steering.

The front end of the front fuselage 2 is driven by an engine 6.
A PTO shaft 16 is provided, which drives a seedling planting claw, which will be described later, and a pair of lower links 17 and one top link 18 provided at the front of the front body 2 are used to drive seedling planting claws, etc., which will be described later. A planting device 19 is attached to be movable up and down. Seedling planting device 19 is transmission case 2
It consists of a plurality of seedling planting units each having seedling planting claws 23, 23 and a float 22 attached to the seedling planting unit 1. 20 is a seedling stand.

In this case, leveling plates 25 for erasing wheel marks are arranged in parallel on the rear hit part 24 of the riding rice transplanter as described above using horizontal bars, and the leveling plates 25 move up and down in conjunction with the lifting and lowering movements of the seedling planting device. In addition to making it possible to move
The hit portion 24 can be adjusted in the vertical direction, and a leaf spring between the horizontal bars can accommodate bending during turning.

That is, the mounting bracket 26 is attached to the hit portion 24.
is rotatably provided so as to be removable, and a support column 27 is attached to this via a pin 29 and a pin hole 28 so that its height can be freely adjusted. A horizontal bar 30 is attached to the support column 27, and the upper end of the leveler 25 is pivotally supported on this.

This horizontal bar 30 has plate springs 41, 41 interposed between the center portion and the side portions.

The lower end of a pipe 32 is pivotally supported on the back side of the leveling plate 25, and this is further supported by a fixed spring receiver 3 of the horizontal bar 30.
3 is inserted.

A spring 35 is wound between the spring receiver 33 and the collar 34 of the pipe 32.

By installing the spring 35 as described above,
The leveling plate 25 is energized toward the field so that the leveling force can be adjusted, and it is located behind each wheel 9, 9, 10, 10, and It is designed so that wheel marks can be erased by twisting it.

A wire 36 is attached to the upper end of the pipe 32, and is extended and connected to a lift arm 42 that constitutes a lifting device for the seedling planting device 19.

37 is a wire outer receiver fixed to the horizontal bar 30, and 38 is a similar wire outer receiver provided at the front end of the front body 2.

Further, 39 is a wire outer.

Furthermore, 40 is another horizontal bar that connects the spring receivers 33, 33, 33, 33, and similarly to the horizontal bar 30 described above, leaf springs 41, 41 are installed between the center part and both side parts. is interposed.

Therefore, when the rice transplanter turns, the leaf springs 41 of the horizontal bars 30, 40 are bent to prevent the horizontal bars from bending.

Since the present invention is constructed as described above, the wheels 9,
9, 10, and 10, the leveling force is constantly adjusted by the spring 35, and the leveling plate 25 is interlocked and connected to the lift arm 42 by the wire 36. When the seedling planting device 19 is pulled up by the lift arm 42 when reversing, the leveling plate 25 resists the force of the spring 35.
Therefore, the leveling board does not push into the field and bend, and since the seedling planting device 19 is lowered when moving forward, it is not pulled up against the force of the spring 35. The leveling plate 25 is lowered by a spring 35, and the leveling force is constantly adjusted by the force of the spring, so that it slides elastically over the field.

By adjusting the height of the support column 27 up and down using the pin 29 and the pin hole 28, the hit part 2
4 is changed, and not only is the setting position of the leveling plate 25 changed to adapt to the depth of the field, but also leaf springs 41, 41, 4 are attached to the horizontal bars 30, 40.
1 and 41, it acts as a buffer and prevents the horizontal bar from bending when turning.

In any case, the present invention is to attach a leveling plate for erasing wheel marks to the rear hitch part via a horizontal bar interposed with a leaf spring, and to connect the leveling plate up and down in conjunction with the lifting and lowering movement of the seedling planting device. Because it is configured to be movable, when the machine backs up or turns, there is no chance of the leveling plate sticking into the field and bending, or the horizontal bar bending.
This has the effect of allowing you to operate the machine smoothly.
