Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bucket-type feeding device for a seeding machine in an agricultural machine.

[Conventional technology]

The bucket-type feeding device of the conventional seeding machine has a fifth
As shown in the figure, a seed feed roll 51 is rotatably provided at the bottom of a seed tank 50.
The seeds that had accumulated on the bottom plate 52 of the 0 were scooped up with a bucket 53.

[Problems to be solved by the invention] In the above conventional bucket type feeding device,
Since the seeds entered below the feed roll 51, a seed pool was formed and it was not possible to feed out the last grain.

[Means for solving problems]

In order to solve the above problems, the present invention has taken the following measures. That is, the feature of the present invention is that a feed-out roll 2 having a bucket 4 protruding from the outer circumferential surface of a roll body 3 is provided at the lower part of the seed tank 1 so as to be rotatable about a horizontal axis. Tank bottom plate part 6 whose edges face each other with a slight gap between
is provided corresponding to approximately the center position in the vertical direction of the feed roll 2, and a recess 7 through which the bucket 4 passes with a slight gap is provided in the bucket passage portion of the tank bottom plate 6, and the recess 7 is provided on the outer peripheral surface of the roll. It extends downward along the length of at least one pitch of the bucket 4.

[Effect]

According to the present invention, the bottom surface of the seed tank is located on the side of the feed roll, and the bottom surface is provided with a recess for passing through the bucket, so that the seeds in the seed tank tend to enter the recess and fall downward. . However, since this recess is longer than the attachment pitch of the bucket, the bucket is always located within the recess, and the seeds that have entered the recess are scooped up by the bucket and do not fall downward from the lower end of the recess. Therefore, all the seeds on the bottom of the seed tank roll down into the recess and are scooped up by the bucket, making it possible to scoop up every last seed.

〔Example〕

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

What is shown in FIG. 1 is a first embodiment of the present invention, and 1 is the bottom of a seed tank of a seeding machine. A bucket-type seed feed roll 2 is provided on the bottom 1 so as to be rotatable around a horizontal axis. This feed roll 2 is constructed by protruding bucket belts 4 at a predetermined pitch in the circumferential direction from the outer circumferential surface of a roll body 3.

The upper part of the feed roll 2 is covered with a cover plate 5. A bottom plate 6 of the seed tank 1 is provided on one side of the feed roll 2 and corresponding to a position approximately in the middle of the feed roll 2 in the vertical direction. The roll-side edge of the bottom plate 6 faces the outer circumferential surface of the roll body 3 with a slight gap therebetween. Further, a recess 7 is formed in the bucket passage portion of the bottom plate 6, through which the bucket 4 can pass with a slight gap.
A bucket passage gutter 8 extends downward from the lower peripheral surface of the recess 7. The shape of the groove 9 of this gutter 8 is the same as the shape of the recess 7 of the bottom plate 6. This bucket passage gutter 8 is provided along the outer circumferential surface of the roll body 3 over a range that is at least longer than the circumferential mounting pitch of the bucket belt 4.

A window 11 flush with the bottom plate 6 is provided in the side wall 10 of the bottom 1 of the seed tank, and a shutter 12 that can be opened and closed is fitted into the window 11. Further, a seed drop tube 14 is extended from the lower end of the side wall 13 on the side opposite to the window 11 side.

According to the first embodiment of the present invention, the seeds 15 in the seed tank accumulate on the bottom plate 6 and fall into the bucket passage gutter 8 from the recess 7 formed in the bottom plate 6. However, this bucket passage gutter 8 is
Because it is longer than the installation pitch of the gutter 8, there is always a
More than one bucket 4 will be located. Therefore, the seeds 15 that have fallen into the gutter 8 are scooped up by the bucket 4 and discharged from the seed drop pipe 14.

FIG. 2 shows a second embodiment of the present invention, which differs from the first embodiment in that the bottom plate 6 is inclined toward the window 11. In this way, attach the bottom plate 6 to the window 11.
By tilting it to the side, there is a capacity for removing the remaining seeds.

The one shown in FIG. 3 is a third embodiment of the present invention, in which the bottom plate 6 is inclined toward the roll 2 side. By tilting it like this, the last 1
Even grains can be dropped into the recess 7.

What is shown in FIG. 4 is another embodiment,
The bottom plate 6 and the gutter 8 are formed by an integral block 16.

Note that the present invention is not limited to the above embodiments.

〔Effect of the invention〕

According to the present invention, the tank bottom plate portion 6 whose edges face the outer circumferential surface of the feed roll 2 with a slight gap,
A concave portion 7 is provided corresponding to approximately the center position in the vertical direction of the feed roll 2, and a concave portion 7 is provided in the bucket passage portion of the tank bottom plate 6 through which the bucket 4 passes with a slight gap. , it is possible to hold the seeds so that they do not fall below the approximate center position in the vertical direction of the feed roll 2. Therefore, unlike the conventional method, the seeds do not enter below the feed roll 2, and the seed pool is prevented from falling. can be effectively eliminated. Moreover, as described above, the seeds can be held at approximately the vertical center of the feed roll 2, so that by rotating the feed roll 2 about the horizontal axis, the seeds on the tank bottom plate 6 can be scooped up by the bucket 4 and rolled out. 2. The distance to lift the seeds upward can be made as short as possible, and the contact time between the bucket 4 and the seeds is also shortened. As a result, the stirring of the seeds by the bucket 4 is extremely reduced. Raking can be done extremely smoothly without any resistance, and it is possible to effectively prevent the coating material from coming off the seeds and damaging the seeds.

Furthermore, since the recess 7 of the tank bottom plate 6 extends downward along the roll outer peripheral surface over at least one pitch of the bucket 4, the bucket 4 is always located within the recess 7. The seeds that have entered the recess 7 are scooped up by the bucket 4 and do not fall downward from the lower end of the recess 7.
Therefore, seeds can be fed out to the last grain, eliminating wasted seeds.
