Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to an agricultural screening and seeding machine. Background Technology

[0002] In agricultural production, seeds need to be sown in tilled soil. Existing seeders struggle to filter out large-diameter stones or branches mixed in with the seeds, affecting their normal growth and development. Therefore, designing a new type of agricultural screening seeder is crucial. For example:

[0003] A Chinese patent publication number CN220211005U discloses an agricultural seeder. The base has a push rod connected to the right end of its upper surface, rollers installed at the bottom, a connecting block engaged inside the left end of the base, a moving mechanism inside the connecting block, a connecting rod connected to the left end surface of the connecting block, and a connecting plate connected to the other end of the connecting rod. A seeding mechanism is located inside the outer casing. A water tank is connected to the upper surface of the base, a water inlet mechanism is connected to the upper surface of the water tank, an intermittent water pump is connected to the bottom outer surface of the water tank, and a water outlet pipe is connected to the outer surface of the intermittent water pump, with the bottom end of the water outlet pipe penetrating the base from top to bottom.

[0004] However, the above-mentioned existing technical solutions have the following drawbacks: they are not convenient for seed screening by the seeder, and at the same time, they are not convenient for the seeder to sow seeds at equal intervals. Therefore, this utility model provides an agricultural screening seeder to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an agricultural screening seeder to solve the problems mentioned in the background art, which make it inconvenient to perform the seed screening function of the seeder and also inconvenient to sow the seeds at equal intervals.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an agricultural screening seeder, comprising a seeder body, a motor installed inside the seeder body, a guide rod provided at the left end of the motor, and a guide block, a guide block provided at the inner end of the guide rod, a limit rod provided at the inner end of the guide block, and a screening frame installed at the inner end of the limit rod, a screening component provided at the inner end of the screening frame, and the screening component comprising a connecting bolt, a connecting frame, and a screen.

[0007] A support frame is provided at the lower end of the seeder body, and a soil covering wheel is provided at the inner end of the support frame. A guide frame is installed at the inner end of the seeder body, and a partition plate is provided at the inner end of the guide frame, and a guide plate is provided at the inner end of the partition plate.

[0008] Preferably, the guide block and the limiting rod are rotatably connected, and the limiting rod has a "T" shaped structure and is symmetrically arranged about the center line of the screening frame.

[0009] Preferably, the inner end of the screening frame is connected to a connecting bolt, and the outer end of the connecting bolt is provided with a connecting frame, and the inner end of the connecting frame is equipped with a screen.

[0010] Preferably, the connecting bolt is threadedly connected to both the connecting frame and the screening frame, and the connecting frame and the screening frame are engaged with each other.

[0011] Preferably, the screen has a "C" shaped structure and is symmetrically arranged about the center line of the connecting frame.

[0012] Preferably, a support plate is provided on the inner side of the support frame, and a soil opener is installed at the left end of the support plate, and a connecting bolt is connected to the inner end of the support plate.

[0013] Preferably, the connecting bolt is threadedly connected to the support plate, and the left end of the support plate has soil-opening tools arranged at equal intervals.

[0014] Preferably, the partition plates are arranged at equal intervals on the guide frame, and the partition plates and guide plates are arranged in a one-to-one correspondence, and the guide plates have an inclined structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the agricultural screening seeder, by adding a vibration screening mechanism inside the seeder, enables seeds that can pass through the holes inside the screen to be sown smoothly. Compared with traditional technology, it has the effect of screening by the seeder. At the same time, an equidistant sowing structure is added to the discharge port of the seeder body to facilitate the sowing of seeds at equal intervals. The specific operation is as follows.

[0016] It is equipped with a screening component and a guide rod. The guide rod moves through a guide block at its inner end. The guide block is rotatably connected to a limiting rod at the outer end of the screening frame. Seeds inside the screening frame are screened through the screen, while larger pebbles or branches remain inside the screening frame, which facilitates the seed screening function of the seeder.

[0017] Equipped with a soil opener and a soil covering wheel, the soil opener turns the soil when the seeder body is pushed. After sowing, the soil covering wheel can flatten the turned and sown land by simply pushing the seeder body, which can improve the efficiency of sowing.

[0018] Furthermore, by arranging the partition plates at equal intervals within the guide frame, the seeds are fed into the cavity formed by the guide frame and two sets of adjacent partition plates, and finally fall onto the turned soil through the inclined surface of the guide plate, making it easier for the seeder to sow the seeds at equal intervals.
