Description

[Detailed explanation of the idea] This invention relates to the seedling planting claws of a rice transplanter.

In recent years, seedlings have been raised using highly viscous granular culture soil, so when planting seedlings in the field using conventional open/close type seedling planting nails, the seedling block adheres to the seedling planting nail due to the viscosity of the seedbed, making it difficult to securely plant the seedlings. There were often situations where this was not possible.

Therefore, the object of this invention is to provide a seedling planting nail that can reliably plant seedlings grown in highly viscous soil such as granular culture soil without adhering to the seedling planting nail.

According to this invention, between the claws of the seedling planting claws that open and close, elastic linear claws are provided that contact the upper surface of the seedling bed and store a biasing force when taking out the seedlings, so that seedlings can be planted when the seedling planting claws are opened. , the seedling block is forcibly pushed out by the biasing force accumulated by the linear claws, and the seedling block is reliably removed without adhering to the seedling planting claws.

Therefore, even if the seedling block has a highly viscous seedbed, it can be reliably removed from the seedling planting nail for planting.

Furthermore, since the claws are linear, they do not damage the seedling stem or leaves, and the structure is simple.

An embodiment of this invention having such characteristics will be described in detail below based on the drawings.

The drawing shows a seedling planting claw of a rice transplanter, and in FIGS. 1 and 2, the seedling planting claw 1 is formed by a left and right pair of a fixed claw 2 and a movable claw 3, and the movable claw 3 is formed by a left and right pair of fixed claws 2 and a movable claw 3. This opening/closing operation is used when taking out seedling blocks from the rice transplanter's seedling stand (not shown), and when planting on the top of the field, the opening and closing operations are performed according to the position.

The base of the fixed claw 2 is attached to the fixing member 5 with a bolt 4, and the base of the movable claw 3 is attached to the movable member 7 with a bolt 6.

An elastic linear claw 8 made of piano wire is located between the fixed claw 2 and the movable claw 3, that is, between the claws of the seedling planting claw 1, and the base of the linear claw 8 is bent. Then, use the aforementioned fixing claw 2.
It is attached to the fixing member 5 by the pole l-4 to which the seedling block is attached, and the free end is located on the upper side of the seedling catcher 9 between the handles 2 and 3, and is folded so as to be in contact with the upper face of the seedling block. The contact portion 10 is formed by bending.

The above-mentioned abutment part 10 is provided at a position where the seedling planting claw 1 enters slightly below the upper surface part of the position where the sound block is normally held, so that when the seedling planting claw 1 takes out the seedling block, the contact part 10
0 is curved in contact with the upper surface of the seedbed, and is provided so that biasing force is stored.

The operation of taking out the seedling block and planting the seedlings by the seedling planting claw 1 configured as described in E is a well-known technique, so the explanation is omitted, but as shown in FIG. When taking out the seedling block 11, that is, when the movable claws 3 are closed from the open state to grip and take out the seedling block 11, the contact portion 10 of the linear claw 8 comes into contact with the upper surface of the seedling block 11 and curves 7. Then, when the seedling block 11 is planted in the field, when the movable claw 3 is opened to release the clamping of the seedling block 11, the linear claw 8 uses the stored biasing force. You can extrude and plant seedling blocks with .

Therefore, even if the seedling block 11 tries to adhere to the claws 2 and 3, the attachment is prevented by the biasing force of the linear claws 8, and the seedling is reliably planted.

In this way, the present invention is formed by a left and right pair of fixed claws 2 and movable claws 3, and the movable claws 3 open and close left and right between the claws of the seedling planting claws 1. A linear claw 8 having elasticity that stores a biasing force in contact with the upper surface is provided, and when the movable claw 3 opens during planting, the seedling block is pushed out and planted by the independent biasing force of the linear claw 8. When planting seedlings, sometimes when the seedling claws open, the force accumulated by the linear claws forces the seedling blocks to be pushed out, and the seedling blocks stick to the seedling claws. Even if the seedling block has a highly viscous seedbed, it can be reliably removed from the seedling planting claw and planted. The structure is simple, and the linear claws 8 can apply biasing force independently from the movable claws 3 and the fixed claws 2, so that the linear claws are not damaged. Even when the fixed claws and movable claws are sufficient for planting, the linear claws can operate reliably without being affected by the movement of the movable claws, especially when the seedling block is strongly attached to the movable claws. However, it has an excellent feature that allows the planting work to be carried out in a sufficiently steady manner.
