Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seed collection device for a seeding machine, and is capable of easily removing the remaining amount of seeds remaining at the bottom of a seed box.

(Prior art) A seeding machine is equipped with a vacuum suction type or various other types of feeding device in a seed box at the bottom of a seed tank, and this feeding device feeds out a predetermined amount of seeds and drops them through a seeding chute, etc. It is designed to let you do so. In this type of sowing machine, after the sowing operation is finished or when changing to other seeds, it is necessary to take out the remaining seeds in the seed box. Therefore, conventionally, an opening for taking out the remaining amount was provided at the bottom of the seed box, and this opening was made openable and closable with a rocking or sliding bottom cover, and the remaining seeds were allowed to fall naturally from this opening. I'm trying to take it out.

(Problem to be solved by the invention) However, the bottom cover is usually located in a location that is difficult to operate within the entire seeding machine, and in the case of a multi-row type, the bottom cover of all seed boxes must be manually removed. Opening and closing operations are complicated, and conventionally it has been difficult to remove the remaining amount of seeds. In addition, in the past, the bottom cover was simply opened and the seeds were taken out by gravity, making it difficult to take them out completely and quickly.When sowing seeds with different seeds, the previous seeds may remain. There were times when I was in trouble.

(Means for Solving the Problems) The present invention aims to solve these conventional problems, and as a specific means for this purpose, a suction hose 24 is provided on the bottom side of the seed box 9 for feeding out seeds. An air suction device 32 is provided in communication with the collection box 22 so that the seeds in the seed box 9 are sucked into the collection box 22 through the suction hose 24 and collected. The air suction device 32 is connected to the seed box 9 via a blowing hose 36 so that the air discharged from the air suction device 32 is blown into the seed box 9.

(Function) When taking out the remaining seeds in the seed box 9, the air suction device 32 is activated. The seeds are collected into the collection box 22. On the other hand, air discharged from the suction device 32 is blown into the seed box 9 via the blowing hose 36.

A filter 35 is provided on the collection box 22 side and is detachably fitted to the cover 31. 36 is a blowing hose, and air suction device 32
Two air pipes are provided across the cover 31 and the seed box 9 so as to blow out the air discharged from the seed box 9 into the seed box 9. This blowing hose 36 is flexible and is provided on the top plate side of the seed box 9 so as to blow air downward.

The installation position of the blow-off hose 36 may be at both the front and rear ends of the left and right sides of the seed box 9 as shown by the solid line, or the blow-off hose 36 on the rear side may be placed at the position of the imaginary line in FIG. , two may be arranged in the direction of the opposing line. 3
Reference numeral 7 denotes a front suppression wheel, which is attached to the tool bar 1 so as to be located in front of the seeding unit 4.

In the above configuration, during sowing work, if seeds are placed in the seed tank 8, they are sent to the seed box 9,
After being adsorbed to the tip side of the seed nozzle 14 of the feeding device 12, the sowing chute 1 is sequentially removed as the feeding device 12 rotates.
5 and let it fall into the seeding furrow. After sowing, the seeds are covered with soil and crushed using the rear crushing wheels 10.

After the sowing operation is completed, the remaining seeds in the seed box 9 are collected as follows.

That is, the motor 34 of the air suction device 32 is activated to rotate the suction fan 33. Then, a suction force is generated, and the remaining seeds on the bottom side of the seed box 9 are sucked and collected together with the air through the suction hose 24 into the collection box 22. After that, they are separated by the filter 35 and the seeds are returned to the collection box 22. It accumulates. In this case, since the pipe 23 is provided in the collection hox 22, the collected seeds do not clog the suction hose 24 and can be collected quickly. On the other hand, the air that has passed through the filter 35 is blown out from above into the seed box 9 through the blow-off nozzle 36, so that the wind force makes it possible to reliably drop the seeds adhering to the inside of the seed box 9. It is also possible to remove other deposits and the like, making it possible to clean the inside of the seed box 9. Furthermore, since the discharged air is blown into the seed box 9, the load on the air suction device 32 can be reduced even if the seed tank 8 and the seed box 9 are sealed. Recovery is possible. Moreover,
The small particles that have passed through the filter 35 return to the seed box 9 and are collected in the collection box 22 while being circulated, so they are safer than those that are discharged to the outside.

The seeds collected in the collection box 22 are
After removing the from the bracket 29 and opening the cover 31,
The collection box 22 may be tilted downward and transferred to another container.

In the above embodiment, the suction hose 24 is connected to the bottom cover 19, but the bottom cover 19 is not necessarily required. Further, the feeding device 12 may be of a roll type, and in that case, the shape of the seed box 9 will naturally be different from that of the embodiment. Therefore, the shape, structure, etc. of the seed box 9 are not limited to the embodiments. Collection box 22 and air suction device 3
2 may be provided in each seeding unit 4, or may be connected to each seed box 9 via a suction hose 24 by providing only one set for all units. Further, the collection box 22 and the air suction device 32 may be provided separately and communicated with each other through a hose. It does not matter whether the seeding machine is for a tractor or a tiller. The structure of the collection box 22 is also not limited to the embodiment.

Further, the collection box 22 is divided into an upper box 22a and a lower box 22b below the grip part 26, as shown by the imaginary line in FIG. 4, and the lower box 22b can be freely inserted and removed from the upper box 22a from below. If the lower box 22b is fitted into the lower box 22b and locked with an engaging claw (not shown) that is linked to the button 36 of the grip part 26, only the lower box 22b can be removed by pressing the button 36. Therefore, there is no need to remove the seeds from the bracket 29 each time the seeds in the collection box 22 are transferred to another container, making the work even easier.

In addition, as shown by the imaginary line on the lower side of FIG. 4, by screwing into the internal screw hole 37 formed in the collection box 22,
It is also possible to attach the container 38 to the collection box 22 in a detachable manner so as to receive the seeds.

(Effects of the Invention) According to the present invention, the remaining seeds in the seed box 7 9 are sucked by the suction force of the air suction device 32 and collected into the collection box 22, compared to the conventional method. The remaining seeds can be taken out easily and reliably. In addition, since the air from the air suction device 32 is blown out into the seed box 9 through the blow-off hose 36, it is possible to remove and clean seeds and other deposits inside the seed box 9.
Even if the seed box 9 side is sealed, the load on the suction device 32 can be reduced, and the suction device 32 can be made smaller.
