Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a cleaning device for a seedling feeding belt in a seedling planting device.

(Prior art) Conventionally, a seedling feeding belt for moving the seedlings placed on the seedling tank with soil downward is provided at the lower end of a seedling tank that moves laterally in a fixed width back and forth by a lateral movement device attached to the machine body, and the belt rotates. There is a known device in which a scraper is brought into contact with the seedling feeding belt and mud is removed by rotation of the seedling feeding belt.

(Problems to be Solved by the Invention) Since the seedling feeding belt attached to the seedling tank of the seedling planting device is in charge of sending the seedlings with soil downward, mud adheres to its surface. Continuing work without removing the muddy soil that has adhered to it will have an adverse effect on the work of feeding seedlings with soil, so a cleaning device has traditionally been installed. However, in the conventional device, a scraper is connected to a rotating seedling feeding belt, and the mud is removed by the rotation of the seedling feeding belt, but the effect cannot be expected to be very high.

The reason for this is that the scraper was installed on the side of the seedling feeding belt, so the mud that was removed was difficult to fall off.

Therefore, in the present invention, cleaning members corresponding to scrapers are fixed to an immovable member, and are made to rub horizontally against each other by horizontal movement of the seedling feeding belt.

(Means for Solving the Problems) Therefore, the present invention moves soiled seedlings placed on the seedling tank downward to the lower end of the seedling tank, which moves horizontally in a fixed width back and forth by a lateral movement device attached to the machine body. In the device provided with a seedling feeding belt, the seedling feeding belt includes a cleaning member whose tip is in contact with the back side of the seedling feeding belt that reciprocates in a fixed width along with the seedling tank, and whose base is fixed to an immovable portion on the left and right sides. This device is used as a cleaning device for a seedling feeding belt in a seedling planting device.

(Example) To explain with reference to an example diagram, 1 is a seedling tank, and the upper end 2 is provided so as to be inclined rearward. 3
is the bottom plate of the seedling tank 1, a window hole 4 is formed at the lower end of the bottom plate 3, guide rolls 5 and 6 are mounted on both upper and lower ends of the window hole 4, and a seedling feeding belt 7 is attached to the guide rolls 5 and 6. pass around. Numerous projections 8 are formed on the surface of the seedling feeding belt 7. A desired number of seedlings 9 are placed on the upper surface of the bottom plate 3 of the seedling tank 1. One of the guide rolls 5 and 6 is a drive type, and the other is a passive type, and the rotational force of the engine of the rice transplanter body is transmitted to the drive type guide roll to rotate the seedling feeding belt 7. , sends out the soiled seedlings 9 downward. Reference numeral 10 denotes an L-shaped seedling receiving plate for receiving soiled seedlings 9, and the seedling tank 1 is provided slidably in the left and right directions with respect to the L-shaped seedling receiving plate 10. That is, as is well known, the seedling tank 1 is moved by rotating the lead cam shaft, which is a lateral movement device for the seedling tank provided on the main body side.
slides back and forth in the left and right directions one share at a time. 11 is L
A planting rod 12 that moves in the direction of arrow A is inserted into the cut 11 at a desired position of the seedling receiving plate 10, so that the seedlings 9 are planted one by one with the planting rod 12. Cut it out and plant it in paddy field 13. 14
is a walking steering handle and is a stationary member. A rod-shaped body 15 projecting toward the seedling feeding belt 7 is provided on the front surface of the walking control handle 14, a brush-shaped brush 16 is attached to the tip of the rod-shaped body 15, and the brush 16 acts on the seedling feeding belt 7. When viewed from the side, the rod-shaped body 15 may be provided in two upper and lower positions as shown in FIG.

In the embodiment shown in FIG. 3, one brush 16 is applied to one seedling feeding belt 7, but in the embodiment shown in FIG. 2 brushes 1 on the left and right for 7
6 comes into play.

(effect) Next, we will discuss the effect.

Place seedlings 9 with soil in the seedling tank 1 as shown in Figure 1,
When you move forward in the rice field holding the walking control handle 14, the planting rod 12 moves the seedlings 9 with soil in the seedling tank 1.
Cut it off from the end and plant it in paddy field 13. When the seedling tank 1 moves to the rear end, a known clutch is disengaged, and the rotation of the engine is transmitted to the guide roll 6, which rotates the guide roll 6 by one plant and feeds out the seedling 9 with soil. . When such work is carried out, mud from the seedlings 9 with soil gradually adheres to the surface of the seedling feeding belt 7. However, in the present invention, the rod-shaped body protruding from the walking control handle 14 Since the brush 16 at the tip of the seedling feeding belt 7 is in contact with the back side of the seedling feeding belt 7, the mud is brushed off by the brush 16 every time the seedling feeding belt 7 rotates. In this case, the brush 16 only partially contacts the seedling feeding belt 7, but does not touch the entire width of the seedling feeding belt 7.
moves left and right as shown in Figure 3, so
The brush 16 comes into contact with the seedling feeder belt 7 evenly, and the soil adhering to the seedling feeding belt 7 is completely brushed off.

(Effects) As mentioned above, in the known method, the scraper is brought into contact with the rotating seedling feeding belt, and the mud is removed by the rotation of the seedling feeding belt, but the effect cannot be expected to be very high. . The reason for this was that the scraper was attached to the seedling feeding belt.
The problem is that the mud that has been removed after all the trouble falls off.

However, in the present invention, a seedling feeding belt 7 is provided at the lower end of the seedling tank 1, which is moved horizontally in a fixed width back and forth by a lateral movement device attached to the machine body, to move the seedlings 9 with soil placed on the seedling tank 1 downward. In this device, the tip (brush portion) of the seedling feeding belt 7 contacts the back side of the seedling feeding belt 7 that reciprocates horizontally over a fixed width along with the seedling tank 1, and the base (rod portion) is fixed to an immovable portion on the left and right sides. Since this is a cleaning device for a seedling feeding belt in a seedling planting device equipped with a cleaning member according to the above, the cleaning member, which does not move from side to side, comes into contact with the seedling feeding belt 7 which moves from side to side.
The mud scraped off by the relative left and right movement is not prevented from falling by the cleaning member, and the cleaning effect is remarkable.
