Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a sowing device for raising seedlings. Background Art

[0002] Seedling cultivation in seedling trays is an important and key link in vegetable production. It not only ensures strong and uniform seedlings, which is conducive to high and stable yields, but also facilitates unified management to reduce the harm of pests and diseases. The conventional operation of seedling cultivation in seedling trays is to sow seeds into the seedling grids of the seedling trays, which are filled with seedling matrix. Each seedling tray has dozens of seedling grids, and dozens or even thousands of seedling trays are needed for each seedling cultivation. Each seedling grid is sown separately, which is labor-intensive and inefficient.

[0003] For example, the application number 202223365144.6 is a seeding device for a seedling tray. The device can select the base plate and seeding plate that match the seed size according to the size of the seeds to be sown, so that the seeding device can be used for seeds of different sizes. The bracket can facilitate the staff to align the seed selection hole and the seeding hole with the seedling grid, thereby improving the accuracy of sowing, avoiding the need for the staff to repeatedly adjust the position of the seed selection tray, and improving the ease of use of the seeding device. However, the device requires manual control of the start and stop of the drop, and the sowing and drop amount are difficult to control.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a seeding device for raising seedlings is proposed. Utility Model Content

[0025] A threaded ring 83 is provided at the upper end of the discharge barrel 4, and a hose 84 is fixedly connected to the lower end of the feed hopper 3. A threaded head 85 is fixedly connected to the lower end of the hose 84. The threaded head 85 is threadedly connected to the threaded ring 83 on the discharge barrel 4. The upper surface of the first fixed frame 2 extends to the lower position and is threadedly connected to a threaded rod 9, and the threaded rod 9 is rotatably connected to the upper surface of the base plate 82. Limiting slide bars 10 are fixedly connected to both sides of the upper surface of the base plate 82. The limiting slide bars 10 are slidably connected to the inside of the first fixed frame 2. By rotating the threaded rod 9, the threaded rod 9 moves up and down in the first fixed frame 2, thereby driving the base plate 82, the discharge barrel 4, the feed hopper 3 and the discharge blade 7 to move up and down to adjust the height of the lower end point of the discharge blade 7.

[0026] Furthermore, a conveyor belt 16 is provided at the top of the conveyor 1 below the discharge barrel 4, a plurality of pushing blocks are bonded to the upper surface of the conveyor belt 16, and a plurality of seedling trays are placed on the surface of the conveyor belt 16, the left outer walls of the plurality of seedling trays are respectively abutted against the side walls of the plurality of pushing blocks, and the conveyor belt drives the plurality of seedling trays to move rightward during the movement to the right, and the pushing blocks limit the seedling trays to prevent the seedling trays from slipping on the conveyor belt.

[0027] Preferably, the leftmost partition of the seedling raising tray is shorter to prevent it from driving the discharge blade 7 to rotate.

[0028] Preferably, the number of seedling raising grids arranged before and after the seedling raising tray is consistent with the number of the discharge barrels 4 and is arranged correspondingly.

[0029] A second fixed frame 11 is fixedly connected to the right side of the upper surface of the conveyor 1, and both ends of the second fixed frame 11 are respectively fixed on the two side walls of the conveyor 1.

[0032] Working principle: When using the seeding device for raising seedlings, first, pour the seeds into the feed hopper 3. During the process of conveying the seedling tray after the soil is pressed by the conveyor 1, the seedling tray moves to the bottom of the discharge barrel 4 in sequence, and the partition of the seedling tray pushes the discharge blade 7, thereby driving the unidirectional rotating shaft 6 and the discharge blade 7 to rotate. During rotation, the seeds falling inside the discharge barrel 4 can fall into the seedling tray with the rotation of the discharge blade 7. Since the partitions of the seedling tray are regularly arranged, the discharge amount of the discharge blade 7 is relatively balanced and the error is small. When the discharge amount needs to be changed according to the discharge amount, the fixed base plate 82 can be removed first. Each mounting plate 81, then unscrew the threaded ring 83 threadedly connected to the threaded head 85, replace the discharge barrel 4 and the discharge blade 7 of appropriate size. After replacing the discharge blade 7 and the discharge barrel 4 of different sizes, the threaded rod 9 can be rotated by the knob at the upper end of the threaded rod 9. Under the limiting action of the limiting slide bar 10, the height of the lower end point of the discharge blade 7 can be adjusted. The sliding frame plate 13 under the sliding covering bucket 12 can be used for soil discharge operation, and the seedling tray after planting can be covered with soil. The scraper 14 can scrape off the excess soil or seeds on the surface of the conveyor belt of the conveyor 1, and the collection box 15 collects them. This is the working principle of the seeding device for seeding.
