Description

[Detailed Description of the Invention] The present invention relates to a seeding device for producing pine seedlings used in a seedling planting machine.

Conventionally, when growing soybeans or the like in a field, seed beans such as soybeans were sown directly in the field and the seeds were grown. However, with this growing method, pigeons and other animals will eat up all the sprouts of soybeans, which are their favorite food, once sprouts emerge from the seed beans.
In areas where there are many pigeons, etc., it has not been possible to obtain a sufficient harvest using the above-mentioned cultivation method. By the way, when the buds of soybeans etc. have grown to a certain length,
There is a tendency for the damage caused by pigeons and the like mentioned above to be significantly reduced. Therefore, in recent years, paying attention to the above-mentioned trend, seed beans such as soybeans are not sown directly in the field, but are grown as pine seedlings in seedling boxes until they reach a predetermined size. Attempts have been made to plant seedlings in fields using a seedling planting machine. Conventionally, as a device for sowing seeds in the seedling bed of a seedling box for producing pine seedlings, a hollow suction chamber is provided inside and communicated with an appropriate suction means, and a plurality of hollow suction chambers connected to the suction chamber are provided on the lower surface of the outside. A seed suction disk is used, which has a seed suction port, and further has a depressurization release means for the suction chamber and a grip portion on the upper surface of the outside. With this device, the user usually holds the grip in his/her hand and carries the seed suction disk over a container in which seed beans such as soybeans are stored, and after adsorbing the seed beans to the seed suction port on the bottom surface, the seed suction disk Transfer the beans onto the seedling box with the bottom side facing down, operate the decompression release means to reduce the degree of vacuum in the suction chamber, and transfer the seed beans that had been adsorbed to the seed suction port onto the seedling bed of the seedling box. Previously, seed beans were adsorbed and sown by dropping them, but as mentioned above, the seed beans are adsorbed with the seed adsorption port facing downward, so the work itself is very difficult. This is difficult, as the seed suction port cannot be seen during the operation, making it impossible to ascertain the adsorption status of the seed beans to the seed suction port, so inexperienced workers may have to turn the seed suction disk over and over again until the seed beans are completely absorbed. It is necessary to adsorb the seed beans while checking the adsorption state of the seed beans.Also, even if a skilled worker is able to completely absorb the seed beans in one suction operation, it may be difficult to check if it is a worker's habit. Therefore, the seed suction disk has to be turned upside down to check the adsorption state, and the work of suctioning seed beans using the conventional seed suction disk, and furthermore, the sowing operation, had the drawback of extremely poor workability.

Therefore, in the present invention, the main body of the seeding device is configured so that the seed suction disc can be set with the seed suction ports provided on the lower surface of the seed suction disc facing upward, and the main body of the seeding device is configured such that the seed suction disc can be set with the seed suction ports provided on the lower surface of the seed suction disc facing upward. The suction disk and the seed alignment plate are configured so that they can be reliably positioned, and the seed suction operation can be performed while visually checking the suction state of the seeds to the seed suction port of the seed suction disk from above. It is an object of the present invention to provide a seeding device that eliminates the above-mentioned drawbacks by allowing seeding work to be performed efficiently.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

The seed suction disk 1 used in this seeding device has a first

The height of the partition plate 16 from the bottom plate 12 is determined by placing the seed sucking disk 1 on the shelves 13 and 15 and placing the seeds on it, as shown in FIGS. 7 and 9 in detail. The upper surface of the seed alignment plate 20 is set to be the same as the upper edge of the partition plate 16 or slightly higher than the upper edge of the partition plate 16 when the alignment plates 20 are stacked, and the work described below is performed. The upper end of the partition plate 16 is set to be lower than the upper ends of the left and right side plates 9, 10 and the front side plate 11 by a predetermined height to prevent the seeds a from scattering. The inside of the main body 7 is divided into a suction disk storage section 17 and a seed storage section 19 by the partition plate 16, and a seed suction disk is arranged on the shelves 13 and 15 of the suction disk storage section 17. 1 is set and the seed alignment plate 20 is set above it, the front ends of the seed suction plate 1 and the seed alignment plate 20 are positioned in contact with the partition plate 16, and their forward movement is prevented. It is becoming more and more common. In addition, as shown in FIGS. 3 and 7, the suction disc housing section 17 is configured such that a predetermined empty space is formed at the lower part of the seed suction disc 1 when the seed suction disc 1 is set. A hose and the like to be connected to the suction pipe 5 can be stored in the space when the work is finished, making it convenient for transporting or storing the device.

As shown in FIG. 5, the seed alignment plate 20 is a plate-shaped body having a rising portion 21 with an inverted L-shaped cross section at the rear and a flat plate portion 22 at the front. A large number of seed alignment ports 23 of the same pitch are provided on the front side excluding the portion 22a on the part 21 side so as to match the large number of seed suction ports 3 provided on the lower surface 1a of the seed suction board 1. As shown by the broken line in FIG. 7, a large amount of seeds a to be absorbed during operation can be stored in the portion 22a. Projections 21a', 21a' are formed at both ends of the horizontal part 21a at the upper part of the rising part 21, and the projections 21a', 21a' are used to hold seeds, as shown in FIGS. 3 and 7. When the alignment plate 20 is set on the seed sucking disk 1, it is secured to the upper ends of the left and right side plates 9, 10 of the main body 7.

As shown in FIG. 6, the scraper 25 has a flat plate shape and has protrusions 25a, 25a formed at both upper ends thereof, and when in use, it is shown in FIGS. As shown, the protrusions 25a, 25a are attached to the left and right side plates 9, 1 of the main body 7.

The dimensions are selected such that a predetermined gap g remains between the tip of the seed alignment plate 5 and the flat plate portion 22 of the seed alignment plate 20.

Since this embodiment has the above configuration,
When performing seeding work, first a predetermined amount of seeds a are stored in the seed storage section 19 of the main body 7, and then the seed suction disk 1 is placed on the shelf section of the main body 7 with the seed suction opening 3 on the lower surface 1a facing upward. 13 and 15. At this time, since the main body 7 has a structure in which the upper and rear sides are widely open, the seed suction disk 1 can be set very easily, and by pressing it forward, it comes into contact with the partition plate 16 and is positioned. Next, the seed alignment plate 20 is attached to the seed suction plate 1.
When the seed alignment plate 20 is placed on top and its front end is brought into contact with the partition plate 16, as shown in FIGS. 3 and 7, further forward displacement of the seed alignment plate 20 is regulated, and A protrusion 21a′ at the rear of the seed alignment plate 20,
21a' is locked to the upper ends of the left and right side plates 9, 10, and connects the seed suction port 3 on the lower surface 1a of the seed suction board and the seed alignment plate 2.
The seed alignment port 23 of No. 0 is aligned. In such a state, after activating the suction means (not shown),
As shown by the broken line in FIG. 7, an appropriate amount of seeds a are transferred from the seed storage portion 19 to a portion 22a near the rising portion 21 of the seed alignment plate 20 and deposited thereon, and then the scraper 25 is moved to the protruding portion 22a of the seed alignment plate 20. 25a, 25a
is guided by the upper ends of the left and right side plates 9, 10, and moves so as to push out the piled seeds a group toward the seed storage section 19, as shown in FIG. Seeds a pass through the seed alignment port 23 of the seed alignment plate 20 and are firmly attracted to the opening of the elastic plate B in the seed suction port 3 of the seed suction board 1. In this state, the seeds a are attracted so that the upper part thereof is almost flush with the upper surface of the seed alignment plate 20, so even if an external force is applied due to the movement of the unadsorbed seeds a, the adsorption state will not be interfered with in any way. In addition, even if the seeds a fly off due to the movement of the scraper 25, the surroundings can be
0 and the front side plate 11, the seeds a do not scatter to the outside of the main body 7 and are effectively scraped into the seed storage section 19. After the scraper 25 has finished suctioning the seeds to the seed suction ports 3, visually check the seed alignment plate 20 to confirm the suction state of the seeds a, and if any unadsorbed seed suction ports 3 remain, try again. Repeat the same operation, or if the number of seeds is small, remove the unadsorbed seeds a by hand.
It can be adsorbed to. After the seeds a are completely absorbed into the seed suction port 3 as described above, when the horizontal portion 21a of the rising portion 21 at the rear of the seed alignment plate 20 is grasped and the seed alignment plate 20 is lifted, the seed alignment plate 20 Since its front end is in contact with the partition plate 16, the seed alignment plate 20 is lifted up so as to rotate around its front end, as shown in FIG. The seed suction disc 1
