Description

[Detailed description of the invention] [Industrial application field] This invention relates to an improvement of a soil-filling machine for a seeding device.

[Prior Art] As shown in FIG. 4, a conventional soil filling machine is provided with a soil conveyor 2 and a horizontal groove-shaped soil discharge port 8 at the bottom of a hopper 1, and the opening height of the discharge port 8 is To adjust h, use the opening/closing slide plate 9 on the hopper 1.
It was fixed by a plurality of bolts 11 through a long hole 10 so as to be movable up and down.

[Problems to be solved by the invention] In the above case, when moving up and down the slide plate 9 for adjusting the opening height h of the discharge port 8, it is necessary to loosen and tighten the bolts 11 each time, which is troublesome. It hung.

This invention was made to solve these problems, and the purpose is to provide a soil filling machine for seeding equipment that allows one-touch adjustment of the soil discharge height by moving a lever. That is.

[Means for solving problems] This will be explained with reference to FIGS. 1 to 3.

The soil filling machine for a seeding device according to this invention is provided with a soil conveyor 2 and a horizontal groove-shaped soil discharge port 3 at the bottom of a hopper 1, and the discharge port 3 has an opening height h.
A partition plate 4 for adjusting the hopper 1 is attached rotatably together with a pivot 5, and a lever 6 having a protrusion 6a at the tip is fixed to the end of the pivot 5.
A has a plurality of engagement holes 7a that engage with the projections 6a.
are arranged at predetermined intervals in a substantially arc shape.

[Function] To adjust the opening height h of the horizontal groove-shaped soil discharge port 3, when the lever 6 provided at the end of the pivot shaft 5 is turned, the partition plate 4 moves up and down using the pivot shaft 5 as a fulcrum. The opening height h can be adjusted. Further, by engaging the protrusion 6a of the lever 6 with the engagement hole 7a arranged in an arc shape, the partition plate 4 is maintained at a predetermined opening degree, and the engagement hole 7a
The opening degree can be judged from the position of .

[Example] An example of this invention will be described based on FIGS. 1 to 3.

1 is a hopper of a soil insertion machine, 2 is a conveyor for transporting soil, 3 is a horizontal groove-shaped soil discharge port, 4 is a partition plate, and support plates 4a, 4a are provided at both ends, and the support plates 4a, 4a are provided at both ends.
A pivot 5 is inserted through and fixed to 4a.

The partition plate 4 is arranged along the discharge port 3, and both ends of the pivot shaft 5 pass through the side plate 1a of the hopper 1, and a lever 6 is fixed to one end thereof.

A protrusion 6a and a catch 6b are provided at the tip of the lever 6, and an engagement plate 7 is fixed to the side plate 1a of the hopper 1, in which a plurality of engagement holes 7a are arranged in a substantially arc shape at predetermined intervals.

Therefore, when the lever 6 is rotated by holding the lever 6b, the partition plate 4 rotates together with the pivot 5, and the opening height h of the discharge port 3 is adjusted by the partition plate 4. That is, when the lever 6 is rotated clockwise, the outlet 3 becomes narrower, and when the lever 6 is rotated counterclockwise, the outlet 3 becomes wider.

Furthermore, the position of the partition plate 4 is fixed by engaging the protrusion 6a of the lever 6 with the engagement hole 7a. Furthermore, the degree of opening of the discharge port 3 by the partition plate 4 can be known from the positions of the plurality of engagement holes 7a.

[Effects of the invention] According to this invention, the opening degree of the soil discharge port can be easily adjusted by simply rotating the lever provided at one end of the partition plate as appropriate. This eliminates the complicated work of loosening and tightening bolts each time the opening is adjusted, which is required in the conventional case where the partition plate is bolted together.
