Description

[Detailed Description of the Invention] The present invention relates to a rice transplanter that is constructed by connecting a pair of left and right support arms connected from a planting device to a pair of left and right lifting arms for the planting device provided on the machine side.

In general, in this type of rice transplanter, manufacturing errors and assembly errors in each structure or member such as the lifting arm and support arm that occur during the manufacturing process, or wobbling in each structure or member that occurs with long-term use, may cause The planting device tends to tilt in the left and right directions with respect to this machine, which may cause the left and right planting depths to be uneven. To avoid this, it is necessary to correct the tilt of the planting device after assembly.

Also, when performing planting work under conditions where the machine tilts from side to side, such as when planting in a ridge, you may want to change the mounting position of the seedling planting device in the left and right direction relative to this machine. be.

The purpose of the present invention is to enable quick, easy, and reliable adjustment operations for changing the horizontal posture of the planting device as described above. Of the connecting parts between the pair of left and right support arms that are connected in series from the machine side and the pair of left and right planting lifting arms provided on the machine side, one is pivotally connected so as to be able to swing, and is fixedly held on the other lifting arm side. The connected pin is inserted into and held by a piece member that moves with the operational rotation of the screwing tool, which is held by the support arm on the corresponding side so that only the operational rotation can be performed. The planter is characterized in that the attitude of the planting device relative to the ground in the left and right directions can be freely changed and adjusted.

That is, in the case of the present invention, a connecting pin fixedly held on the other lifting arm side is connected by a piece member that moves in accordance with the operational rotation of the screwing tool, which is held by the other support arm so that only the operational rotation can be freely performed. By changing the center position, you can freely change and adjust the horizontal position of the planting device on the ground, so it is useful when assembling or planting in locations with different conditions, as mentioned above. The necessary horizontal position change adjustment of the planting device relative to the ground can be quickly and easily performed by an extremely simple operation such as rotating a screw tool.

Moreover, since the screw is rotated, fine adjustments can be made, and the planting device can be reliably changed to the desired ground posture.

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

Figure 1 shows a rear-mounted riding rice transplanter.At the rear of the tractor body (hereinafter referred to as the machine), there is a seedling stand 2A that can be moved back and forth in the left and right directions, and a mud surface at the planned planting location. a float 2B for leveling the ground, and a seedling planting claw 20 for planting the seedlings in a bucket unit taken out from the seedling platform 2A onto the mud surface leveled by the flow 2B.
A planting device 2 consisting of, etc. is arranged.

A pair of left and right upper support arms 3, 3 and a lower support arm 4, 4 are pivotally connected to the planting transmission case 2D of the planting device 2 in a concentric manner, and the above-mentioned upper support arms 3, 3
The front ends of the planter are connected to a pair of left and right planting lifting arms 5, 5 provided on the side of the machine 1, and the front ends of the lower dissection support arms 4, 4 are connected to the rear hitch 6 of the machine 1, respectively. The planting device 2 is driven to move up and down by vertically swinging the lifting arms 5, 5.

゛The lifting arms 5, 5 and the upper support arm 3,
The planting device posture changing device of the present invention, which is constructed between the device and the device 3, is constructed as shown in FIGS. 2 and 3.

That is, a U-shaped first connecting member 7 that opens rearward and is connected to the free end portions of the lifting arms 5, 5, and a first connecting member 7 that opens forward that is provided at the front end portions of the upper support arms 3, 3. Of the connecting portions A and B at the left and right circular portions that connect the second connecting member 8 in the shape of a letter 8 with the second connecting member 8 fitted into the first connecting member 7, one The first connecting pin 9 is inserted into and engaged with the connecting holes 7a and 8a formed in the connecting members 7 and 8, respectively.

On the other hand, the second connecting pin 10 is inserted and engaged between the engaging hole 7b formed in the first connecting member 7 and the elongated hole 8b formed in the second connecting member 8, and the second connecting member At the tip of a screw 12 with an operating knob 12A, which is inserted through a split pin 11 into 7 and held so that only the operating knob 12A can be freely rotated, a bridge member 13 that moves in the front-rear direction of the fuselage as the screw 12 is rotated is attached. The second connecting pin 10 is inserted into and held by the piece member 13, and the second connecting pin 10 is moved by the movement of the piece member 13 as the screw tool 12 is rotated. By swinging the connection center position of the planting device 2 around the other connection pin 9, the attitude of the planting device 2 relative to the ground in the left and right directions can be freely changed and adjusted.
