JPS601529Y2 - Line drawing tool for rice transplanter - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a line drawing device for a rice transplanter for drawing a line as a guide for the direction of movement in the next step, and more particularly to a line drawing device using a chain.

Conventionally, the above-mentioned line-drawing tools had annular bodies connected in series with pivots, which had the disadvantage that when it touched an obstacle such as a clod of soil, the line would curve left and right, causing the drawn line to meander. .

The present invention attempts to suppress such meandering of the wire drawing tool with a relatively simple structure.

That is, the present invention is characterized in that a chain that can only be bent in a plane is attached so that it can be bent as freely as possible along the vertical plane in the longitudinal direction of the fuselage, or in the direction along S゛, when in use. .

In other words, since it uses a chain that can only flex in two directions, rather than in two directions, it has a relatively simple structure, but even if the chain touches an obstacle, it will not flex to the left or right, and will continue to meander. We were able to reliably suppress this and achieve our intended purpose.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

A rice transplanting device 2 is connected to the rear of a traveling body 1 equipped with steering wheels and drive wheels so that it can be driven up and down and the rice transplanting device 2 can be driven, and the rice transplanting device 2 is operated by operating a hydraulic control valve provided on the traveling body 1 side. It is configured to maintain a partial level on the ground, and while leveling the mud surface with the leveling plate 3 and float 4 of the rice transplanting device 2, a seedling block for one plant is taken out with the seedling planting claw 5 and the mud is removed. A riding-type rice transplanter is used to plant rice on the surface.

Arms 6 are pivotally connected to the left and right sides of the traveling body 1 so as to be rotatable around the front and rear axes, and a link is connected to the tip of the arm 6 so that the tip can be bent only in a plane (one direction) and the tip A chain 7 having a weight is attached to the swinging rod 8, which is operated to swing relative to the fuselage 1, so that when in use, it can be freely bent along the vertical plane in the longitudinal direction of the fuselage, or in the direction along S゛. Attach it as much as possible, use the swinging rod 8 to project the arm 6 to the outside of the machine body, and throw a part of the chain 7 under the mud surface. It is designed so that it can be exchanged for an unused state by raising it above the mud surface.

The chain 7 has its respective links 7a... pivotably connected to be rotatable only about the horizontal axis The chain 7 is curved to prevent the chain 7 from meandering, and each link 7a... rotates vertically around the horizontal axis X to avoid obstacles and maintain a straight line on the mud surface. It is structured so that it can be pulled.

The arm 6 is constructed using a parallel four-speed link mechanism, and when the arm 6 is in use or not in use, the chain 7
The link part 6a, which is attached to the fuselage, is constructed so as to always follow the vertical plane in the longitudinal direction of the aircraft, or along S゛, so that when it is not in use, the chain 7 hangs down and rotates only around the transverse horizontal axis X. Therefore, the chain 7 is designed to prevent the chain 7 from protruding laterally outward when it is not in use.
