Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an improvement of a soil filling machine for an automatic seeding machine.

[Conventional technology]

Seedling boxes are sequentially transferred onto a conveyor, and after being supplied with bed soil by a soil filler, seeds are sown by a seeding machine, and then covered with soil again by a soil filler. Finally, irrigation is performed by a water supply machine.

When supplying or covering soil with the soil filling machine, a cylindrical brush is rotated to level the surface of the soil, but at the same time the height of the soil is adjusted. The brush is supported on both the left and right sides, and it is necessary to separately adjust the height position of the left and right sides of the brush each time the bed is filled with soil and covered with soil.

[Problem that the invention seeks to solve]

Since the height adjustment of the brushes as described above is performed separately for the left and right sides, there is a problem in that it requires a considerable amount of effort for the operator.

This invention was made in consideration of the above-mentioned problems, and once the height of the brush is adjusted to the zero reference point, the left and right heights of the brush can be adjusted simultaneously with a single operation. It was made possible.

[Means for solving problems]

This will be explained with reference to the drawings.

The soil filling machine for an automatic seeding machine according to the present invention includes frames 3, 3 respectively disposed along both sides of a conveyor 1 that carries a seedling raising box 2 and moves in the F direction;
An arm 4 having a base 4a supported on the outside of the frames 3, 3 and having a distal end 4b supporting a soil leveling brush 5 and having a built-in drive transmission mechanism;
Bearings 6 erected at the intermediate portions of the arms 4,
an intermediate shaft 7 whose both ends are pivotally supported by
, height-adjustable adjustable bases 9, 9 provided at the upper end of the support column 8, and a polygonal column-shaped block placed on the adjustable bases 9, 9 and having the intermediate shaft 7 eccentrically inserted therethrough. 10, 10 and
By rotating the intermediate shaft 7 in the G direction or the H direction, the arm 4, 4 and brush 5
This allows for fine adjustment of the height.

[Effect]

The adjustable base 9 is adjusted so that the lower end of the outer periphery of the brush 5 almost touches the upper surface of the outer frame of the seedling box 2 when the left and right blocks 10, 10 are both at the zero reference point (D in the figure). Then, when the intermediate shaft 7 is turned to expose the rotating surfaces B, A, and C in accordance with the soil filling and covering of the floor, the left and right height positions of the intermediate shaft 7 are simultaneously adjusted.

〔Example〕

Embodiments of the invention will be described based on the drawings.

1 is a conveyor that carries seedling boxes 2; 3;
3 is a frame arranged along both sides of the conveyor 1, 4, 4 is an arm, the base part 4a, 4a is pivotally supported on the outside of the frame 3, 3, and the tip part 4b, 4b is a soil leveling brush 5. The brush 5
It has a built-in drive transmission mechanism to rotate. The drive transmission mechanism is of course driven by a motor (not shown). Reference numerals 6 and 6 denote bearings erected at the intermediate portions of the arms 4, 4, respectively, and pivotally support both ends of an intermediate shaft 7 that extends horizontally over the conveyor 1.
Reference numerals 8 and 8 denote pillars erected on the frames 3 and 3 on both sides, and screw-type adjustable bases 9 and 9 are provided at the upper ends, respectively. Numerals 10 and 10 are polygonal column-shaped blocks which eccentrically penetrate and fix the intermediate shaft 7, and are placed on the adjustable bases 9, 9. Reference numeral 11 denotes a knob provided at one end of the intermediate shaft 7, which allows the blocks 10, 10 to be rotated around the axis together with the intermediate shaft 7.

Then, the left and right adjustable bases 9, 9 are adjusted so that the lower end of the outer periphery of the brush 5 touches the upper surface of the outer frame of the seedling growing box 2 when both the left and right blocks 10, 10 are at the zero reference point. As shown in FIG. 3, the intermediate shaft 7
The height change is shown. That is, in the state shown in FIG. 3, the vertical distance of S to P is dmm,
If the block 10 is turned clockwise with the knob 11 by one stop in the direction of the arrow E, the above distance becomes Cmm, and if it is turned one step at a time, it becomes amm and bmm.

Therefore, in order to make it easier for the operator to see the height of the intermediate shaft 7, it is preferable to indicate the perpendicular distance on each rotating surface of the block 10. For example, in the state shown in FIG.
, and write C, A, and B in order. In this way, the operator can immediately know the height of the intermediate shaft 7 by looking at the number on the top surface of the block 10.

Since the change in the height of the intermediate shaft 7 corresponds to the change in the height of the arms 4, 4 and the brush 5, the brush 5 can be adjusted by simply turning the block 10 with the knob 11.
The height can be adjusted. Incidentally, the height can also be adjusted using the adjustable bases 9, 9.

〔Effect of the invention〕

According to this invention, the height of the brush 5 of the earth-filling machine is digitally adjusted by rotating the intermediate shaft 7 inserted through the polygonal columnar block 10 having four rotating surfaces A, B, C, and D. It is possible to easily adjust the height of a plurality of types, so that the operator does not have to spend a lot of time and effort on adjusting the height separately for the left and right sides, unlike in the past.
