Description

Double type needle seeder for big size seeds}

The present invention relates to a double type seeding machine for allelic seeds.

It is designed to be used for sowing of large crops compared to other crops with different particle sizes and weights, such as watermelon and pumpkin lamp.

Since pumpkin (or gourd) seeds are flat, long, large and heavy compared to seeds of other crops, they have to be relied on without a crop because of problems that cannot be sown by conventional seeders that are adsorbed using compressed air.

In sowing of crops, many sowing methods using mechanization have been developed. As a seeding system for crops having small seed particles, devices such as those of the applicant (Patent No. 105777, Utility Model Registration No. 102414, Utility Model Registration No. 276983) have been developed and used.

4 is a view showing an embodiment of a use state of Utility Model Registration No. 276983. The seed adsorbed from the seed substrate is raised to a certain height and then dropped to the center of the tray. In these devices, there was a problem that the seed of crops that could be sown was limited to crops of watermelon seed size or less.

On the other hand, in recent years, in order to produce grafted seedlings of watermelon, seedlings of pumpkins or gourds are seeded and transplanted into a large tree (root part) of watermelon, but the seeding work is not mechanized. There was a problem that needs to be progressed, and a device is needed to accurately carry out the seeding of large grain seeds and to increase the work efficiency.

The present invention is designed to solve the above problems and to accurately sow seeds with large particles such as watermelon and pumpkin.

In the present invention, the needle end waiting on the seed substrate is attached to one end of the needle with a strong suction pressure, while delaying the end of the seed for a predetermined time. The seed thus attached was configured to fall to the center of the tray. To prevent the seed from being separated from the needle tip by each obstacle while moving the attached seed from the seed stand to the center of the tray, the movement range of the needle tip is moved upward from the seed stand board to the drop guide at the top of the tray. It was configured to fall by rotating.

In addition, by configuring a pair of nozzle stand with a needle, it is characterized in that the operation time is reduced by alternately driving one nozzle stand per row of the tray cell.

The seed drill main body 1 constituting the present invention is composed of a transfer portion configured to transfer the tray, and a seeding portion dropping the seed inside each cell of the tray.

The transfer unit was driven to drive the stepper motor to drive the conveyor belt 7 from the control panel 9 inputted by calculating the traveling distance and the like according to the shape of each tray 11 so as to ensure an accurate transfer distance at all times.

The seeding part is mounted on the upper end of the conveyor belt 7, and the seeding part is symmetrically formed on the left and right sides, and the seed supply hopper 3 and the seed stand substrate 2 are formed.

The lower end of the seed supply hopper (3) is open to form a discharge hole of the size of the seed (8), the seed stand substrate (2) is attached to the lower end in an inclined form. The seed supply hopper (3) connected to the seed holding substrate (2) is configured to inject the seed upwards of the seed holding substrate through the discharge port (4) due to the fine vibration, so that a certain amount is always placed on the seed holding substrate.

The seed holding plate 2 is formed so that the tip is formed in an inclined shape so that the seeds are easily collected at the tip, so that the tip of the nozzles 6a and 6b and the seed 8 are easily contacted. A pair of nozzle posts 5a and 5b are mounted in a position adjacent to each seed waiting substrate 2, and the nozzle posts have the same number of nozzles 6a and 6b as the number of cells 12 of the tray 11. Is attached, and the end of the nozzle is formed at a position facing the center of the cell 12 of the tray. A drop guide 10 is mounted between adjacent seed stand substrates 2 so as to accurately guide the falling seed to the center of the cell 12 of the tray.

The seeding operation is performed while each nozzle stage 5a, 5b operates sequentially. First, the nozzle stand 5b on one side adsorbs the seed 8 while applying a strong suction pressure to the end of the nozzle 6b in the seed stand substrate 2. Seeds are larger and heavier than those of other crops, so one seed per nozzle is attached. At this time, the nozzle unit 5a on the other side is in the injection position at the top of the drop guide 10.

After the adsorption, the nozzle stand 5b is rotated to the upper end and positioned at the upper end of the drop guide 10. As the pressure is released, the seed falls to the center of the tray cell 12 through the drop guide 10. The movement radius of the nozzle end reciprocates in the range of 270 ° from the seed substrate 2 to the upper end of the drop guide 10.

The nozzle 6a on the other side is likewise rotated 270 ° in the reverse direction to undergo the step of seed suction on the seed substrate 2 on the other side. The reciprocating rotation of each nozzle stage 5a, 5b is controlled at the correct angle by a pneumatic cylinder (not shown) controlled by the control panel 9, and the suction and pressure release are also configured to be automatic.

The nozzles 6a and 6b attached to each nozzle stage 5a and 5b are formed in the same number as one row of tray cells, and each end faces the center of the cell. Due to such a structure, one nozzle stage is seeded per one row constituting the cell, so that one cell row per one reciprocating rotation of each nozzle stage is completed so that the seeding time is shortened.

The reason why the nozzle stages 5a and 5b are configured to rotate about 270 ° from the seed stand substrate 2 to the upper end of the drop guide 10 is to move the seed stand substrate 2 and the drop guide 10 in close proximity. When moving, it is not only obstruct the nozzle rotation due to each component, it is configured to rotate to the top due to the problem that the height between the nozzle stem (5a) (5b) and the cell of the tray can be increased.

Therefore, the nozzle end and the soil part of the cell center make the closest contact, and thus the impact falling upon seed drop can be reduced, so that the seed is planted in the center to achieve work accuracy.

By constructing so that seeds with large particles can be accurately and quickly sown, seeds can achieve automatic sowing of crops such as large crops (watermelon, pumpkin), etc., which has labor saving effect by manpower sowing and shortening of sowing time. Due to this has the effect of contributing to the production of high-quality agricultural products.
