Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a novel electric seeding device. Background Art

[0002] Rice, wheat, corn and other crops play a very important role in my country's grain production, but most parts of my country still rely on traditional cultivation methods, which are labor-intensive and inefficient. Machine direct seeding is the simplest planting method in rice light cultivation technology. The sowing device will directly affect the quality, cost and future quantitative work of crop cultivation.

[0003] In the prior art, the sowing device includes a seed box, a plurality of electric seeding devices are arranged on the lower side of the seed box, a seeding tube is connected to the lower side of the electric seeding device, and seeds are contained in the seed box. When the electric seeding device is working, the electric seeder discharges the seeds into the seeding tube, and the seeds fall to the ground along the seeding tube. It is easy for soil or other debris to enter the seeding tube, causing seed blockage. When the seeds are blocked, the seeding tube can only be disassembled, which is troublesome to operate. When removing the debris in the seeding tube, the seeding tube is very long and the debris is difficult to clean. Summary of the invention

The front soil retaining plate and the rear soil retaining plate respectively cover the seeding box in the length direction, and the lowest positions of the front soil retaining plate and the rear soil retaining plate are lower than the lowest position of the seeding box. In this design, a structure for opening a seeding groove is provided in front of the seeding box, and a structure for covering soil is provided behind the seeding box. During the process of opening the seeding groove and covering soil, the soil generated during the opening of the seeding groove will be thrown backward, and the soil generated during the covering soil will be thrown forward. The setting of the front soil retaining plate and the rear soil retaining plate respectively blocks the soil at the front and rear sides, and the soil will not enter the seeding box and will not block the seeds.

A fixing part 12 is fixedly arranged on the outer side of the seeding box 13, and a connecting hole 10 and a connecting hole 2 11 are respectively opened on the connecting part 9 and the fixing part 12. When the seed cleaning door 1 is closed, the connecting hole 10 and the connecting hole 2 11 are coaxial; the seeding box 13 extends vertically downward, and a seed dropping opening is opened on the lower side of the seeding box 13, and the seed dropping opening is communicated with the seed dropping cavity, and the seed dropping cavity is communicated with the inoculation cavity.

[0021] In order to further avoid seeds piling up in the seeding box 13, a front soil retaining plate 5 is fixedly connected to the front side of the lower part of the seeding box 13, and a rear soil retaining plate 6 is fixedly connected to the rear side of the lower part of the seeding box 13. The front soil retaining plate 5 extends forward and downward at an angle, and the rear soil retaining plate 6 extends backward and downward at an angle. The front soil retaining plate 5 and the rear soil retaining plate 6 respectively cover the seeding box 13 in the length direction, and the lowest positions of the front soil retaining plate 5 and the rear soil retaining plate 6 are lower than the lowest position of the seeding box 13.

[0022] In order to further improve the reliability of seeding, a plurality of seeding ports 15 corresponding to the positions of the seeding devices are arranged on the seeding box 4, and a seeding assembly 14 is provided between two adjacent seeding ports 15. Between two adjacent seeding ports 15, the seeding assembly 14 includes a seeding plate 1402 and a seeding plate 1401. One end of the seeding plate 1402 is flush with the edge of one seeding port 15, and the other end of the seeding plate 1402 extends upward at an angle, and the other end of the seeding plate 1402 is connected to one end of the seeding plate 2 1401, and the other end of the seeding plate 2 1401 extends downward at an angle, and the other end of the seeding plate 2 1401 is flush with the edge of the other seeding port 15.

The seed cleaning door body 1 can be opened and closed. A control box is arranged in the cab, and the control box is electrically connected to the alarm. The missed seeding sensor 7 sends the detected seed drop signal to the control box. If no seeds fall into the inoculation cup 2 within the set time, the missed seeding sensor 7 sends the missed seeding signal to the control box, and the control box controls the alarm to sound and light alarm; all electric seeding devices 3 are connected through a seeding shaft 16, and the seeding shaft 16 is the electric seeding device 3 The power input is driven by the motor to drive the seeding shaft 16 to rotate (this is the prior art, and the connection structure between the motor and the seeding shaft 16 is not drawn); the seeding box 13 is in the shape of a rectangular parallelepiped and is hard. When the seeds fall along the seeding box 13, they fall in a wide band and will not pile up seeds; before sowing, open each seed cleaning door body 1 to observe whether the seeding box 13 is blocked. If it is blocked, clean the debris in the seeding box 13. If it is not blocked, close the seed cleaning door body 1, and use the connecting pin to connect the seed cleaning door body 1 to the seeding box through the connecting hole 10 and the connecting hole 2 11. 13, without human intervention, the seed cleaning door 1 will not be opened, and the seeds can only fall along the sowing box 13 to ensure the reliability of seeding; during the sowing process, the front soil retaining plate 5 and the rear soil retaining plate 6 respectively block the soil in the front and rear, and when the soil is thrown onto the front soil retaining plate 5, the soil bounces forward under the action of the front soil retaining plate 5, and when the soil is thrown onto the rear soil retaining plate 6, the soil bounces backward under the action of the rear soil retaining plate 6, and the soil will not enter the sowing box 13; during the sowing process, the seeds in the sowing box 4 are moved along the sorting plate 1 1402 and the sorting plate 2 140 1 moves evenly toward the direction of each seeding opening 15, so that each seeding opening 15 is filled with seeds, further ensuring the reliability of sowing; the present invention facilitates the cleaning of debris in the sowing box 13, avoids the blocking of seeds in the sowing box 13, and improves the reliability of sowing; the joint arrangement of the front retaining plate 5 and the rear retaining plate 6 prevents soil from entering the sowing box 13, and it is not easy for seeds to pile up in the sowing box 13. In addition, the arrangement of the seed separation component 14 makes each seeding opening 15 evenly filled with seeds, further improving the reliability of sowing; it can be applied to sowing work.
