Description

[Detailed Description of the Invention] The present invention relates to a seed extraction device for a seeding machine such as a submerged soil seeding machine.

Generally, this type of seed sowing machine sows a predetermined amount of seeds by feeding them from a seed hopper in synchronization with the running of the machine. In such a seeding machine, it is necessary to remove the seeds remaining in the seed hopper when the seeding operation is finished or when the type of seeds is changed. Therefore, in the past, an opening/closing plate was provided at the exit of the residual seeds in the seed hopper, and the opening/closing plate was opened to take out the remaining seeds. Since the locking member is designed to be stopped by a member, opening and closing operations using the locking member are troublesome, and the locking member may be damaged due to insufficient locking or severe vibration during work. The seed hopper often comes off during work, and the seeds placed in the seed hopper may spill onto the field, which is not a desirable method.

The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation, and is designed to constantly close the outlet with a biased opening/closing plate to prevent inadvertent opening during work. In addition to being able to reliably prevent
To provide a seed take-out device for a seed seeding machine, which allows opening and closing of a take-out port to be quickly performed by a very simple one-touch operation of an operating lever without the trouble of locking and disengaging a locking member as in the past. In particular, the opening/closing plate provided at the outlet for removing residual seeds in the seed hopper is biased toward the outlet closing side, and the opening/closing plate is configured to always close the outlet. At the same time, an operating lever swingably provided on the opening/closing plate is movably passed through a through hole provided on the lower side of the seed hopper to enable the opening/closing operation of the opening/closing plate, and a control lever is provided in the through hole. is characterized in that a notch provided in the operating lever when the opening/closing plate is in the open position is connected with a narrow locking portion that is fitted and locked only when the operating lever swings.

Next, the present invention will be explained in more detail based on an embodiment shown in the drawings. In the drawings, reference numeral 1 denotes a traveling body, and a flooded soil seeding machine 3 is attached to the rear of the traveling body 1 via a link mechanism 2 so as to be vertically movable. That is, a pair of left and right frames 4 connected to the rear end side of the link mechanism 2 are provided with parallel pipes 5 and 6 facing in the left-right direction, and a rolling shaft 7 is attached to the front pipe 5.
is attached so that the seeding machine 3 can be swung in the left and right direction. Further, on the rear pipe 6, three sets of rice field sliding bodies 8 and three seed hoppers 10 are mounted symmetrically via a mounting body 9 and a mounting plate 10a, respectively. Further, 11 is a groove plate provided on the rice field slide 8, and 12 is a soil covering plate, in which seeds fed from the seed hopper 10 are sown into the seeding grooves made by the groove plate 11, as will be described later. After that, by covering the soil with a soil covering plate 12, in this embodiment, sowing in flooded soil is performed.

On the other hand, the seed hopper 10 is configured so that the seeds are sequentially fed out to the feeding cylinder 10b side by the rotation of the feeding body 14 in synchronization with the running speed of the traveling machine, and the seeds are dropped into the seeding groove and sown. However, an opening/closing plate 15 is attached to the bottom plate 10c of the seed hopper 10 via a hinge 15a so as to be rotatable downward, and an outlet for removing the remaining seeds is provided in the bottom plate 10c. 10d can be opened and closed. Further, a base end portion of an operating lever 16, which is approximately L-shaped so that the distal end thereof serves as a handle, is pivotally attached to the bottom surface of the opening/closing plate 15 via a bracket 16a so as to be freely swingable via a pivot shaft 16b. Further, below the opening/closing plate 15, a guide box 17 is fastened to the seed hopper 10 with bolts 17a, and the guide box 17 has a through hole 18 through which the operating lever 16 passes. The intermediate portion of the operating lever 16 passes through the through hole 18 in a movable manner to allow the opening/closing operation of the opening/closing plate 15. 19 is interposed, and the opening/closing plate 15 is normally pressed against the edge of the outlet 10d to tightly close the outlet 10d. On the other hand, when the operating lever 16 is operated downward against the biasing device 19, the opening/closing plate 15 is rotated downward and the opening/closing plate 15 is rotated downward.
0d is opened, and the seeds in the seed hopper 10 fall and are discharged downward from the discharge port 17b provided in the guide box 17. A notch 16c is formed at a position corresponding to the through hole 18 in
Only the notch 16c is fitted and locked in the swinging direction,
A narrow locking hole 18a that cannot be inserted is provided in communication with the other parts of the operating lever 16, and after the operating lever 16 is in the opening state of the opening/closing plate 15, it can be moved in the direction of the arrow X as shown in FIG. By swinging the notch 16c into the locking hole 18a, the cutout 16c can be fitted into the locking hole 18a and the outlet 10d can be kept open.

In the embodiment of the present invention configured as described above, the sowing work in flooded soil using the seeding machine 3 is as follows:
As the traveling body 1 travels in the field, seeds are fed out from the seed hopper 10 and dropped into the seeding groove formed by the groove plate 11 by rotation of the feeding body 14 timed to the machine traveling speed. After that, the seeding furrow is covered with soil using the soil covering plate 12.

When sowing in flooded soil is completed in this way, it is necessary to remove the seeds remaining in the seed hopper 10, but in the present invention, the remaining seeds can be removed extremely easily. That is, the outlet 10d provided in the bottom plate 10c of the seed hopper 10
is normally closed by the opening/closing plate 15 energized by the energizing bullet 19. Therefore, in order to open the opening/closing plate 15, it is sufficient to pull the operating lever 16 downward against the biasing bullet 19.
In this open state, the operating lever 16 is swung in the direction of arrow X, and the notch 16 provided in the operating lever 16 is
c is inserted and locked into the locking portion 18a connected to the through hole 18, the operating lever 16 is moved to the locking portion 18a.
Therefore, the opening/closing plate 15 is maintained in the open state. Therefore, the remaining seeds are transferred from the outlet 10d to the outlet 16 of the guide box 16.
The seeds are discharged to the outside of the seed hopper 10 via the seed hopper 10, and are completely collected by receiving them in a tray 20 or the like. When the collection of the remaining seeds is completed, the operating lever 16 is swung in the opposite X direction, and the locking portion 18 of the operating lever 16 is rotated.
The locking and holding by a is released, and as a result, the opening/closing plate 15 is rotated upward by the biasing force of the biasing bullet 19 and automatically closes the outlet 10d. As described above, according to the present invention, the opening and closing operations of the opening/closing plate 15, which were conventionally troublesome, can be performed by an extremely simple one-touch operation of the operating lever 16 as described above.

Moreover, the notch 16c provided in the operating lever 16
If the operation lever 16 is not operated to the open state of the opening/closing plate 15 against the biasing device 19, the locking portion 1
The width is narrow so that it does not get caught in 8a, and
Since the mounting opening 10d is always closed by the opening/closing plate 15 which is elastically biased by the biasing bullet 19, there is no need to forget to close the opening/closing plate 15.
There is no inconvenience such as the opening/closing plate 15 being opened inadvertently due to vibrations or the like during work.

In addition, the seeding machine of this embodiment is attached to the traveling machine body 1 side by the front pipe 5 facing in the left-right direction,
A seed hopper 10 and a rice field sliding body 8 are attached to a rear pipe 6 parallel to the front pipe 5. Therefore, by holding both the pipes 5 and 6 in parallel, the overall weight can be reduced without any reduction in strength, and the seed hopper 1
0 and the paddy surface sliding body 8 are integrally attached to the same rear pipe 6, so it is possible to completely eliminate any deviation in the trench cutting and soil covering position relative to the sowing position, and it is possible to significantly improve the sowing accuracy. In addition, the seed hopper 1 is symmetrical with respect to the left and right center of the aircraft.
This has advantages such as being able to arrange various members such as 0 and so on, and achieving excellent left-right balance.

In summary, the present invention is configured such that the opening/closing plate provided at the outlet for removing residual seeds in a seed hopper is biased toward the outlet closing side so that the opening/closing plate always closes the outlet. An operating lever, which is swingably provided in the seed hopper, is movably inserted through a through hole provided on the lower side of the seed hopper to enable the opening and closing operation of the opening/closing plate, and the through hole further includes:
When the opening/closing plate is in the open position, the notch provided on the operating lever is connected to a narrow locking part that fits and locks only when the operating lever swings. To remove the remaining seeds from the container, all you have to do is swing the operating lever with the opening/closing plate pulled against the biasing force to fit the notch into the locking part and lock the opening/closing plate. To close the door, simply swing the operating lever that is fitted into the locking part to release the notch from the locking part, and the opening/closing plate will automatically close due to the biasing force. Once in the closed state, the opening/closing operation of the opening/closing plate can be reliably performed with a very simple one-touch operation of the operating lever, and there is no need for the troublesome operation of locking/unlocking the locking member as in the past. .
Moreover, when the opening/closing plate is always blocking the outlet,
Since the outlet is elastically biased to close, there is no chance of it opening accidentally due to severe vibrations during work.
