Description

[Detailed description of the invention] The present invention consists of forming a seedling rest into a plurality of sections along the width direction, and facing each seedling resting surface to prevent the seedlings from floating up from the seedling rest. The present invention relates to a seedling floating prevention device for a seedling stand, which is provided with a seedling floating prevention rod that can be swingably switched between a lower receiving position and an upper receiving release position.

Such a seedling floating prevention device is used during planting work.
While preventing the seedlings from floating and allowing the seedlings to be taken out properly using the planting claws, by switching the blocking rod to the receiving and releasing position, the seedlings can be replenished onto the seedling stand. The purpose of this project is to provide a structure for fixing the blocking rod in the receiving position, and a structure for fixing the blocking rod in the receiving position. The aim is to simplify the overall configuration by modifying the structure for swinging operation.

To explain in more detail, conventionally, as shown in FIG.
A locking rod 25 is attached to the end of the engaging recess 24 to fix the blocking rod 23 in the receiving position.
The locking rod 25 is slidably supported through the swing arm 22 so as to be able to engage with the locking rod 25.
A knob 26 for rotating the support rod, which also serves as a support for sliding the locking rod 25, is attached to the end of the locking rod 25, but this requires a large number of parts and is difficult to manufacture and assemble. In addition, multiple seedling floating prevention rods are attached to one long support rod so that the seedling floating prevention rods for multiple seedling surfaces can be switched at the same time. By attaching a plurality of blocking rods to the long support rod, the torsion of the long support rod that occurs when the upper catch is released is dealt with by increasing the shaft diameter, so it is desirable to reduce weight. This has the disadvantage of increasing the weight of the rice transplanter.

The present invention aims at simplifying the operation while reducing the number of parts, simplifying the overall configuration, and reducing the weight.

The characteristic configuration of the present invention is that in the above-mentioned seedling floating prevention device for the seedling rack, a seedling floating prevention rod at a position opposite to each of the seedling loading surfaces is installed over the entire width of the seedling rack. A curved part for hooking a finger for sliding and rotating the long support rod by being fixed to the long support rod of the book and bending one end side of the long support rod; A locking rod for the engagement recess for fixing the blocking rod at the receiving action position is integrally formed, and the elongated support is further provided at the middle portion in the width direction and the other end side of the elongated support rod. Along with a locking rod installed at one end of the rod,
There is no restriction rod-shaped member for the engagement recess for fixing the seedling floating prevention rod at the receiving position.

Next, the effects of the feature configuration of the present invention will be described.

That is, the locking rod for fixing the blocking rod in the receiving position is integrally formed with the support rod by bending one bar, and the locking rod for locking and releasing the locking rod is formed integrally with the support rod. In order to swing the support rod, the curved part for hooking fingers for sliding and rotating the support rod is formed by bending the one rod, so the simple structure of bending one rod is possible. Therefore, it is possible to construct a structure for fixing the blocking rod in the receiving position and a structure for swinging the blocking rod, and by reducing the number of parts,
This is advantageous in terms of production and assembly, and as a result, a device for preventing seedlings from floating on a seedling stand that can be used more conveniently as a whole has been obtained.

The long support rod is attached to the long support rod so that the seedling floating prevention rod for multiple seedling placement surfaces can be switched at once, but the long support rod is designed to prevent twisting of the long support rod that occurs when the upper support is released. Since it is configured to be prevented by a regulating rod provided in the middle, there is no need to increase the shaft diameter of the long support rod to deal with twisting, and by providing a small regulating rod, the long support rod can be prevented from twisting. While reducing the weight of the support rod, it is possible to switch multiple seedling floating prevention rods into action and non-action at the same time.For example, a seedling floating prevention rod that can be independently oscillated and switched according to the surface on which each seedling is placed. Compared to a structure in which a rod is provided, that is, a short support rod with a small diameter is provided with a seedling floating prevention rod, the posture of multiple seedling floating prevention rods can be changed at once.
The switching operation of the seedling floating prevention rod can be simplified.

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figure 1 shows a seedling planting device installed in a walk-behind rice transplanter, in which a seedling platform 1 is tilted and moved laterally with a constant stroke, and the seedling platform 1 is driven to rotate each time it reaches the end of its stroke. A star wheel-shaped seedling feeder 2 is used to feed the pine seedlings W on the seedling tray to the lower end side, and as it is driven to circulate up and down, it sequentially takes out seedlings one by one from the lower end of the seedling tray. The structure is such that planting claws 3 for planting seedlings are provided, respectively, so that the seedling planting work can be carried out.

Then, as shown in FIG. 2, the seedling stand 1
, so that four pine-shaped seedlings W can be placed along its width direction, so that four rows of seedlings can be planted at the same time, and each pine-shaped seedling W can be placed on a seedling stand. A pine-shaped seedling W is attached to a seedling floating prevention rod 4 that prevents the seedling from floating from
It is provided so that two each act on the
The mounting structure of the blocking rod 4 will be described in detail below.

As shown in FIGS. 1 to 3, three brackets 5 are attached to the upper surface of the side frame 1A of the seedling stand 1.
A support rod 6 is slidably and rotatably supported through the support rod 6, and the lower end of the blocking rod 4 is attached to the support rod 6 by welding, so that the blocking rod 4 is moved to the downward receiving action position. It is designed so that it can be switched and swung to the upper detent release position.

A hole 7 as an engagement recess formed in one end of the three brackets 5 to fix the blocking rod 4 in the receiving position and the receiving release position.
A locking rod 8 that engages with the locking rods a and 7b is integrally formed with the support rod 6 so as to be connected to the end of the support rod 6 by bending one rod, and in order to lock and release the locking rod 8, In order to swing the blocking rod 4, the finger hooking curved part 9 for sliding and rotating the supporting rod 6 is positioned between the end of the supporting rod and the locking rod 8, and It is formed by bending a bar. Further, a spring 10 is provided for urging the support rod 6 so as to urge the locking rod 8 toward the engagement side, and a spring 10 is provided for urging the support rod 6 to urge the locking rod 8 toward the engagement side. A rod-shaped member 11 that comes into contact with an object and restricts the biasing movement range of the support rod 6
