Technical Field
[0001] This utility model relates to the field of agricultural production technology, and in particular to an automatic chili seedling planter. Background Technology
[0002] With social development and the increasing demand for chili peppers, the planting area of chili peppers has been expanding. Traditional manual sowing methods are difficult to meet the needs of large-scale planting. They are not only inefficient but also consume a lot of manpower, and the sowing quality is inconsistent. Therefore, a mechanical device that can efficiently and accurately sow chili pepper seedlings is needed to improve production efficiency and quality. As a result, the automatic chili pepper seedling sower was developed.
[0003] However, the following technical problems still exist in existing seeding equipment:
[0004] Some existing equipment uses the suction-rotation sowing principle. During the rotation process, the excessive rotation force may easily throw the seeds out of the sowing area, resulting in uneven and inaccurate sowing, which in turn affects the emergence rate and sowing quality of chili seedlings.
[0005] Many existing devices may lack sufficient automation in the placement of the burrowing basins, often requiring operators to place the basins one by one onto the conveyor belt, which consumes a lot of manpower and time, resulting in relatively low work efficiency.
[0006] The existing sowing equipment is not equipped with a device to spray water on the sown area, which cannot provide the necessary moisture conditions for seed germination in a timely and appropriate manner, thus affecting the germination effect.
[0007] In response to this technical problem, this application proposes an automatic chili seedling planter. Utility Model Content
[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic chili seedling planter. This device achieves telescopic suction and release seeding, which is precise and stable, improves seeding quality, and the hopper can be closed to prevent seeds from falling out. It can also spray water to provide moisture to the seeding area. At the same time, it improves the degree of automation, eliminating the need for manual placement of seedlings one by one, making it convenient to use.
[0009] To achieve the above objectives, the present invention provides the following technical solution:
[0010] An automatic chili seedling planter includes a pushing platform, a cavity fixedly connected to the top of the pushing platform, a pushing port at the bottom outer side of the cavity, a sliding groove at the center of the bottom of the pushing platform, a fixing block fixedly connected to the rear end of the bottom of the pushing platform, a motor fixedly connected to the front end of the bottom of the pushing platform, a lead screw fixedly connected to the drive end of the motor, the lead screw being connected to the sliding groove via a nut seat, clamping devices fixedly connected to both sides of the nut seat, the lead screw being rotatably connected to the fixing block, support columns fixedly connected to the four corners of the bottom of the pushing platform, a fixing frame fixedly connected to the rear of the support columns, a conveyor belt at the front end of the fixing frame, a conveyor belt at the rear end of the fixing frame, and a soil covering box fixedly connected to the front end of the top of the fixing frame.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of an automatic chili seedling planter, comprising a pusher platform 1. The pusher platform 1 is characterized by: a cavity 2 fixedly connected to its top, the cavity 2 serving to hold seedling trays 3; a pusher opening 4 at the bottom outer side of the cavity 2; a sliding groove 6 at the center of the bottom of the pusher platform 1; a fixing block 10 fixedly connected to the rear end of the bottom of the pusher platform 1; and a motor 7 fixedly connected to the front end of the bottom of the pusher platform 1. A lead screw 8 is fixedly connected to the drive end of the motor 7, and the lead screw 8 is connected to the sliding groove 6 via a nut seat 9. Clamping devices 11 are fixedly connected to both sides of the nut seat 9. The lead screw 8 is rotatably connected to the fixing block 10. The main working principle of this structure is that before sowing, the operator places the seedling trays 3 into the cavity 2, at which point the motor 7 is started. Motor 7 drives lead screw 8 to rotate. Lead screw 8 engages with nut seat 9, driving clamping device 11 to move to a designated position. Before moving, clamping device 11 is in a state of clamping the seedlings 3 at the push port 4. Its cooperation with motor 7 and lead screw 8 can move the seedlings 3 onto conveyor belt 13. This structural design improves the automation level of the equipment, eliminating the need for operators to place the seedlings 3 one by one. Support columns 5 are fixedly connected to the four corners of the bottom of the push platform 1. A fixed frame 12 is fixedly connected to the rear support column 5. Conveyor belt 13 is installed at the front end inside the fixed frame 12, and conveyor belt 2 14 is installed at the rear end inside the fixed frame 12. A soil covering box 16 is fixedly connected to the front end of the top of the fixed frame 12. The function of soil covering box 16 is to fill the seedlings 3 before sowing. A layer of soil is applied, and a pressure roller 17 is rotatably connected to the top front end of the fixing frame 12. The pressure roller 17 can compact and level the soil that has just been applied to the seed tray 3, providing a stable soil environment for seed germination and promoting better rooting and sprouting. A scraper 18 is fixedly connected to the top front end of the fixing frame 12, which can clean up excess soil on the seed tray 3 to avoid interfering with subsequent sowing operations. A fixing seat 19 is slidably connected to the top middle of the fixing frame 12. Multiple telescopic rods 20 are fixedly connected to the front side of the fixing seat 19, and a pressing block 21 is fixedly connected to the top of the telescopic rods 20. The pressing block 21 is used to press out sowing holes on the leveled soil in the seed tray 3, facilitating subsequent sowing. At the same time, the fixing seat 19 has a sliding connection structure. This system allows for control over the depth of the sowing holes. A hopper 22 is fixedly connected to the top center of the fixed frame 12, storing the seeds to be sown. A cover plate 23 is rotatably connected to the top of the hopper 22. After the seeds are poured into the hopper 22, the cover plate 23 can be closed to prevent seeds from falling out of the hopper 22 due to vibrations during sowing. Multiple discharge ports 45 are provided at the rear end of the cover plate 23. An air suction sowing device 24 is fixedly connected to the top center of the fixed frame 12, and a drop pipe 46 is fixedly connected to the bottom of the air suction sowing device 24. A spray gun 29 is fixedly connected to the rear end of the top of the fixed frame 12. The spray gun 29 is connected to a water tank 36 via a water pipe 35. Multiple nozzles 30 are provided at the bottom of the spray gun 29 for spraying water onto the sown area.To provide the necessary moisture for seed germination, a soil covering box 31 is fixedly connected to the top and rear end of the fixing frame 12. A cleaning brush 32 is installed at the top and rear end of the fixing frame 12, which can clean and level the soil surface of the seedling trays 3 after sowing.
[0032] Reference Figure 2 , Figure 5 and Figure 6 Multiple acupoints 3 are slidably connected inside the cavity 2. After the equipment is started, the acupoint 3 at the bottom push port 4 is pushed out, and the acupoints 3 above will fall back to the push port 4 due to gravity. The clamping device 11 includes a support frame 42. A telescopic rod 3 43 is fixedly connected to the top of the support frame 42 on one side. A clamping plate 44 is fixedly connected to the top of the telescopic rod 3 43. Rubber pads are fixedly connected to the clamping plate 44 on one side. This can increase the friction and have a good clamping and fixing effect, while avoiding damage to the clamped parts. Multiple rollers are provided on the inner side of both the first conveyor belt 13 and the second conveyor belt 14. The cylinder 47 and roller 47 are rotatably connected to the fixed frame 12. Multiple rollers 47 at the rear end of conveyor belt 13 and near the end of conveyor belt 2 14 are connected by belt 15. Motor 2 34 is fixedly connected to the right side of the roller 47 at the rear end of conveyor belt 2 14. Motor 2 34 drives the roller 47 at the rear end of conveyor belt 2 14. Then, the roller 47 at the front end of conveyor belt 2 14 drives the roller 47 at the rear end of conveyor belt 13 via belt 15. A placement platform 33 is set at the rear end of the fixed frame 12. The function of the placement platform 33 is that after the seeding work is completed, the seedling trays 3 will be transported to the placement platform 33 by conveyor belt 2 14. The top is for staff to inspect or move to a designated position. Both the first and second soil covering boxes 16 and 31 are slidably connected to a baffle 41 on their rear sides. The baffle 41 can flexibly adjust the amount and speed of soil covering according to actual needs. The air suction seeding device 24 includes multiple telescopic rods 25, with an air suction chamber 26 fixedly connected to the top of each telescopic rod 25. Multiple suction heads 27 are provided on the front side of the air suction chamber 26. The air suction chamber 26 is connected to the fan 40 via an air pipe 28. Unlike the existing seeding equipment that uses suction and rotation for seeding, this front-to-back telescopic suction and release method will be more stable and precise, avoiding rotational issues during rotation. In case the seeds are thrown out of the sowing area due to excessive force, a dust collection box 39 is installed at the bottom of the fixed frame 12. The dust collection box 39 is installed directly below the projection of the connection between conveyor belt 13 and conveyor belt 2 14. It can effectively collect the soil scraped off by the scraper 18, avoid the soil accumulation on the equipment and affect the sowing work, and keep the working environment clean. A water inlet 37 is opened at the top right side of the outer wall of the water tank 36, which makes it easy to replenish the water source. A glass window 38 is set at the rear right side of the outer wall of the water tank 36, which makes it easy to observe the water level in the water tank 36.
[0033] Working principle: First, the worker places the seed tray 3 into the cavity 2 and pours seeds into the hopper 22, then closes the cover plate 23. Next, the motor 7 is started to drive the lead screw 8 to rotate, which drives the clamping device 11 to move the seed tray 3 clamped at the push port 4 in the cavity 2 onto the conveyor belt 13. The seed tray 3 above will fall to the push port 4 due to gravity and wait to be transferred. When the seed tray 3 moves on the conveyor belt 13, it is covered with soil by the covering box 16, compacted and leveled by the pressure roller 17, and the scraper 18 removes excess soil. Then, the telescopic rod 20 on the front side of the fixed seat 19 drives the pressing block 21 to press out the sowing hole on the leveled soil, and the depth can be controlled. At the same time, the fan 40 in the air suction sowing device 24 creates negative pressure in the air suction chamber 26, and the suction head 27 sucks up the material through the discharge port 45 of the cover plate 23. Seeds are sown into the planting holes through the hopper 22 and the dropper 46. The subsequent planting holes 3 are driven by the first conveyor belt 13 and the second conveyor belt 14 (the second motor 34 drives the rear roller 47 of the second conveyor belt 14 to the rear roller 47 of the first conveyor belt 13 via the belt 15). First, water is drawn from the water tank 36 by the spray gun 29 through the water pipe 35 and sprayed through the nozzle 30 to keep the soil moist. Then, the soil is covered again by the second covering box 31 and cleaned and leveled by the cleaning brush 32. Finally, the planting holes 3 are transferred to the placement platform 33. During the process, the dust collection box 39 collects the scraper 18 to scrape off the debris. The water tank 36 can be replenished through the water inlet 37 and the water level can be observed through the glass window 38. The back baffle 41 of the first covering box 16 and the second covering box 31 can flexibly adjust the amount and speed of soil covering.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
