Abstract
Description
Technical Field
[0001] This utility model relates to agricultural planting, and more particularly to a soil covering device for a field planting mulch seeder. Background Technology
[0002] The field planting mulch seeder is an important piece of equipment in agricultural production used for sowing and mulching. It can simultaneously complete a series of operations in the field, including ditching, sowing, fertilizing, and mulching, greatly improving sowing efficiency and quality and creating a good start for crop growth. The matching soil covering device quickly covers the seeds and mulch with soil after the sowing and mulching processes are completed, providing a suitable germination environment for the seeds, preventing the mulch from being blown away by the wind, and effectively ensuring the smooth emergence and healthy growth of crops.
[0003] The soil covering device mainly consists of a soil covering box, a mixing mechanism, a conveying component, an adjusting component, and a power connection component. The soil covering box stores the soil to be covered; the mixing mechanism, located inside the covering box, consists of a mixing shaft and blades and is responsible for mixing and loosening the soil; the conveying component commonly includes a screw conveyor or a belt conveyor, which transports the mixed soil to the designated location; the adjusting component can adjust the thickness and width of the soil covering; and the power connection component is connected to the mulching seeder to obtain power to drive the operation of all components of the soil covering device.
[0004] The inlet of the soil covering device's covering box is designed to be too small, unable to accommodate larger clods of soil or debris, and lacks a pre-crushing or screening structure. Furthermore, the inlet is too close to the internal mixing mechanism, causing soil to be drawn into the mixing before it is fully dispersed, easily leading to blockages. Additionally, if the shape and rotation speed of the mixing blades are not properly adjusted, they may fail to effectively disperse the soil, causing it to accumulate near the inlet. Blockages in the inlet can result in unstable covering volume, affecting seed germination and the effectiveness of the mulch film, reducing sowing quality, and in severe cases, even interrupting sowing operations and delaying planting seasons. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a soil covering device for a field planting mulch seeder, which aims to improve the problem that soil accumulation near the feed inlet of the soil covering device and feed blockage can lead to unstable soil covering, affecting seed germination and the mulch film fixing effect.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a soil covering device for a field planting mulch seeder, comprising a fixed frame, a plurality of soil covering wheels rotatably connected to the bottom of the fixed frame, a soil covering box fixedly connected to the top of the soil covering wheels, a feed bin fixedly connected to the top of the soil covering box, a motor fixedly connected to the top of the soil covering box, a transmission wheel fixedly connected to the output end of the motor, and a material shaking component provided on the side wall of the transmission wheel;
[0007] The material shaking assembly includes a side platform and a universal joint. The side platform is fixedly connected to the side wall of the transmission wheel, and the universal joint is rotatably connected to the side wall of the side platform. A transmission rod is rotatably connected to the side wall of the universal joint. A feed cylinder is slidably connected inside the feed hopper. A rotating frame is rotatably connected to one end of the transmission rod. The rotating frame is rotatably connected to the outer wall of the feed cylinder. A spraying assembly is provided at the bottom of the fixed frame.
[0008] Furthermore, the spray assembly includes a water tank and spray nozzles, the water tank being disposed at the bottom of the mounting frame, and a plurality of spray nozzles being fixedly connected to the bottom of the water tank.
[0009] Furthermore, a lifting platform is fixedly connected to the bottom of the fixed frame, and a fixed platform is fixedly connected to the bottom of the lifting platform.
[0010] Furthermore, the feature is that: an electric push rod is fixedly connected to the bottom of the lifting platform, and a slide is fixedly connected to the output end of the electric push rod.
[0011] Furthermore, a plurality of push platforms are fixedly connected to the lower surface of the slide, and a support platform is fixedly connected to the top of the water tank.
[0012] Furthermore, the support platform has multiple sliding columns slidably connected inside, and the top of each sliding column is rotatably connected to a pulley.
[0013] Furthermore, a spring is fitted on the outer wall of the sliding column, and the pulley is slidably connected to the bottom of the push platform.
[0014] Furthermore, one end of the spring is fixedly connected to the top of the support platform, and the other end of the spring is fixedly connected to the top of the sliding column.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the motor first drives the transmission wheel to rotate the side platform on its side wall, so that the feed cylinder slides repeatedly inside the feed bin to avoid soil blockage and accumulation, ensuring that operations such as sowing and mulching are carried out smoothly as planned, without delaying the farming season due to frequent shutdowns for cleaning due to blockage, and ensuring that crops can be planted at the appropriate time.
[0017] 2. In this utility model, the electric push rod outputs to the slide table, causing the slide table to slide at the bottom of the fixed platform. This repeatedly triggers the trigger point at the top of the water tank, achieving uniform spraying of the soil by the nozzle. This avoids soil clumping or localized excessive or insufficient thickness, allowing the soil to form good porosity and aeration, thus providing a suitable soil environment for seed germination and root growth.

Detailed Implementation
[0023] 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.
[0024] Reference Figures 1-2 An embodiment of this utility model is provided: a soil covering device for a field planting mulch seeder, including a fixed frame 1, a plurality of soil covering wheels 2 are rotatably connected to the bottom of the fixed frame 1, a soil covering box 3 is fixedly connected to the top of the soil covering wheels 2, a feed bin 4 is fixedly connected to the top of the soil covering box 3, a motor 5 is fixedly connected to the top of the soil covering box 3, a transmission wheel 6 is fixedly connected to the output end of the motor 5, and a material shaking component is provided on the side wall of the transmission wheel 6;
[0025] The material shaking assembly includes a side platform 7 and a universal joint 8. The side platform 7 is fixedly connected to the side wall of the transmission wheel 6, and the universal joint 8 is rotatably connected to the side wall of the side platform 7. A transmission rod 9 is rotatably connected to the side wall of the universal joint 8. A feed cylinder 11 is slidably connected inside the feed hopper 4. A rotating frame 10 is rotatably connected to one end of the transmission rod 9. The rotating frame 10 is rotatably connected to the outer wall of the feed cylinder 11. A spraying assembly is provided at the bottom of the fixed frame 1.
[0026] Specifically, when the field planting mulch seeder is performing soil covering operations, and soil feeding is required, the motor 5 is first turned on. The transmission wheel 6 starts to rotate under the drive of the motor 5, and the side platform 7 connected to its side wall rotates together with the transmission wheel 6. The rotation of the side platform 7 transmits power to the transmission rod 9 through the universal joint 8, causing the transmission rod 9 to rotate. The other end of the transmission rod 9 is connected to the rotating frame 10. The rotation of the transmission rod 9 further causes the rotating frame 10 to rotate on the outer wall of the feed cylinder 11. During the rotation, the rotating frame 10 pushes and pulls the feed cylinder 11. The feed cylinder 11 and the feed bin 4 have a sliding connection structure. Under the action of the rotating frame 10, the feed cylinder 11 slides repeatedly inside the feed bin 4, effectively disturbing the soil entering the feed bin 4 and preventing soil blockage and accumulation in the feed bin 4. This ensures that sowing, mulching, and other operations are carried out smoothly as planned, without frequent machine stops for cleaning due to soil feeding blockage, thus avoiding delays in farming and ensuring that crops can be planted at the appropriate time.
[0027] Reference Figure 3 The spray assembly includes a water tank 21 and spray nozzles 22. The water tank 21 is located at the bottom of the fixed frame 1. Multiple spray nozzles 22 are fixedly connected to the bottom of the water tank 21. A hanging platform 12 is fixedly connected to the bottom of the fixed frame 1. A fixed platform 14 is fixedly connected to the bottom of the hanging platform 12. An electric push rod 13 is fixedly connected to the bottom of the hanging platform 12. A slide 15 is fixedly connected to the output end of the electric push rod 13. Multiple push platforms 16 are fixedly connected to the lower surface of the slide 15. A support platform 17 is fixedly connected to the top of the water tank 21. Multiple sliding columns 18 are slidably connected inside the support platform 17. A pulley 19 is rotatably connected to the top of the sliding column 18. A spring 20 is sleeved on the outer wall of the sliding column 18. The pulley 19 is slidably connected to the bottom of the push platform 16. One end of the spring 20 is fixedly connected to the top of the support platform 17, and the other end of the spring 20 is fixedly connected to the top of the sliding column 18.
[0028] Specifically, after the soil covering process is completed in the field, when irrigation is needed, the electric push rod 13 outputs power to the slide table 15. The slide table 15 slides at the bottom of the fixed platform 14. As the slide table 15 slides, multiple pushers 16 alternately push multiple pulleys 19. Under the push of the pushers 16, the sliding column 18 moves inside the support platform 17. During the process of the pushers 16 pushing the pulleys 19 to move the sliding column 18, the spring 20 is continuously compressed and rebounded. With the help of the elastic force of the spring 20, the sliding column 18 moves on the support platform. The slide column 18 slides repeatedly inside the water tank 21. The top of the slide column 18 corresponds to the trigger point on the top of the water tank 21. The repeated sliding of the slide column 18 causes the trigger point on the top of the water tank 21 to be repeatedly triggered. The water tank 21 is connected to the nozzle 22. After the trigger point is repeatedly triggered, the water in the water tank 21 is sprayed out through the nozzle 22, which can achieve uniform spraying of the soil. This can avoid soil clumping or local excessive thickness or thinness, and allow the soil particles to be evenly dispersed, forming good porosity and aeration, providing a suitable soil environment for seed germination and root growth.
[0029] Working principle: First, when feeding the soil for covering, motor 5 is started. Motor 5 outputs power to the transmission wheel 6, driving the side platform 7 on its side wall to rotate. The side platform 7, connected to the universal joint 8, further drives the transmission rod 9 to rotate, causing the rotating frame 10 to rotate on the outer wall of the feeding cylinder 11, pushing and pulling the feeding cylinder 11. This allows the feeding cylinder 11 to repeatedly slide inside the feeding bin 4 to prevent soil blockage and accumulation, ensuring that sowing, mulching, and other operations proceed smoothly as planned. Frequent shutdowns for cleaning due to blockages will not delay agricultural activities, ensuring that crops can be planted at the appropriate time. When it is necessary to clean the soil after covering... During irrigation, the electric push rod 13 is activated, which outputs power to the slide table 15, causing the slide table 15 to slide at the bottom of the fixed platform 14. At this time, multiple pushers 16 at the bottom of the slide table 15 alternately push multiple pulleys 19, causing the sliding column 18 to slide repeatedly inside the support platform 17 through the elastic force of the spring 20. This causes the trigger point at the top of the water tank 21 to be repeatedly triggered, achieving uniform spraying of the nozzle 22 onto the soil. This avoids soil clumping or localized excessive or insufficient thickness, allowing the soil to form good porosity and aeration, providing a suitable soil environment for seed germination and root growth.
[0030] 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.
