Description

Technical Field

[0001] This utility model relates to the field of sowing and soil-laying technology, specifically to a two-stage transmission synchronous soil-laying sowing device. Background Technology

[0002] The dual-stage drive synchronous soil-laying seeding device originated from the needs of agricultural mechanization. Traditional manual sowing is labor-intensive and inefficient. Although existing sowing equipment has achieved a certain degree of automation, it suffers from limited functionality, difficulty in precisely controlling sowing spacing and depth, and uneven soil spreading affects seed burial depth and germination rate. Furthermore, some equipment also suffers from soil clogging and insufficient seed placement accuracy. To improve sowing efficiency and quality and reduce manual labor, the dual-stage drive synchronous soil-laying seeding device was developed, aiming to achieve simultaneous sowing and soil spreading, thereby enhancing agricultural production efficiency.

[0003] Utility model patent CN216415055U discloses a seeding and covering machine, including a control box and a drive device. The control box houses a servo motor, with a running screw fixedly connected to its output end. A moving block is threaded onto the running screw, and a connecting plate is fixedly connected to one side of the moving block. A covering machine control head is located at one end of the connecting plate, and an external drive motor is located on one side of the covering machine control head. A rotating rod is fixedly connected to the output end of the external drive motor, and a drive wheel is located at one end of the rotating rod. The rotation of the servo motor drives the running screw fixedly connected to its output end to rotate, which in turn moves the moving block threaded onto the running screw. The movement of the moving block moves the connecting plate fixedly connected to one end of the moving block up and down, which in turn moves the covering machine control head at one end of the connecting plate up and down, changing its height.

[0004] Although the integrated seeding and covering machine can adjust the height of the covering device to facilitate deep covering in farmland with different environments, it still has the following problems in practical use: the drive unit, covering machine, and seed conveyor belt rely on multiple motors for separate operation, resulting in action delays, increasing seed exposure time, and the lack of soil compaction function, which reduces seed germination rate. Therefore, we propose a two-stage transmission synchronous soil-laying seeding device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, such as the delay in action and the reduction in seed germination rate caused by multiple drive sources, it is desirable to provide a two-stage drive synchronous soil-laying seeding device.

[0006] In a first aspect, this application provides a two-stage transmission synchronous soil-laying seeding device, including a support plate. A soil-covering component and a soil-pressing component are sequentially arranged below the support plate from front to back. A seeding component is also snapped onto the support plate in front of the soil-covering component. The seeding component includes a vertically distributed and interconnected seed storage hopper and a seeding tube. A rotating wheel is rotatably snapped onto the seeding tube near its top. Several seeding slots are formed on the circumferential sidewall of the rotating wheel. A drive motor is installed on the top surface of the support plate. The output shaft of the drive motor is coaxially connected to a drive shaft that passes through and rotatably connects to the support plate. A first bevel gear and a second bevel gear are coaxially connected to the bottom end of the drive shaft and to the top of the support plate, respectively. The soil-covering component includes two soil-covering discs and a soil-covering bevel gear coaxially connected to one of the soil-covering discs and simultaneously meshing with the first bevel gear. The soil-pressing component includes a soil-pressing roller.

[0007] According to the technical solution provided in the embodiments of this application, a seeding motor is fixedly installed on the top surface of the support plate on one side of the seeding tube. The output shaft of the seeding motor is coaxially connected to the rotating wheel. The number of seeding slots is at least three and they are distributed in a ring at equal intervals.

[0008] In this setup, the seeding motor drives the rotating wheel to rotate, causing the seeds to fall evenly as the seeding trough rotates.

[0009] According to the technical solution provided in the embodiments of this application, two soil covering frames are fixedly connected to the bottom surface of the support plate, and the two soil covering discs are respectively rotatably connected to the bottom ends of the two soil covering frames.

[0010] In this setup, the soil covering frame is rotated to connect the soil covering disc, enabling the soil covering disc to be stably covered.

[0011] According to the technical solution provided in the embodiments of this application, the two soil-covering discs are at an angle with their openings facing the direction of the seeding tube, and the angle range is 30°-60°. The two soil-covering discs do not contact each other on the side that is close to each other, and the two soil-covering discs are symmetrically distributed about the vertical center line of the seeding tube.

[0012] In this setup, two symmetrical soil-covering discs ensure that the soil fully covers the seed furrow.

[0013] According to the technical solution provided in the embodiments of this application, the two soil-covering discs are coaxially connected to rotating rods on their relatively uniform sidewalls, and the ends of the two rotating rods that are close to each other are coaxially connected to meshing steering bevel gears.

[0014] In this setup, the two soil-covering discs rotate in the same direction via a steering bevel gear.

[0015] According to the technical solution provided in the embodiments of this application, a pair of roller frames are fixedly connected to the bottom surface of the support plate behind the soil covering component, and the soil pressing roller is rotatably engaged between the bottom ends of the two roller frames;

[0016] In this setup, the soil compaction rollers are engaged by rotating the roller frame to ensure that the soil is compacted after covering.

[0017] According to the technical solution provided in the embodiments of this application, the soil compaction assembly further includes a soil compaction bevel gear meshing with the second bevel gear. The roller shaft of the soil compaction bevel gear is rotatably inserted into a support block fixed on the top surface of the support plate. The roller shafts of the soil compaction bevel gear and the soil compaction roller are coaxially connected to a transmission wheel on the same side. The two transmission wheels are connected by a transmission belt.

[0018] In this setup, the earth-pressing roller is driven by the meshing of the second bevel gear and the earth-pressing bevel gear, as well as the transmission connection between the drive wheel and the drive belt.

[0019] According to the technical solution provided in the embodiments of this application, a furrow opener is installed on the bottom surface of the support plate in front of the seeding pipe, and a pusher frame for easy pushing by workers is fixedly connected to the support plate behind the soil pressing component.

[0020] In this setup, a furrow opener is used to prepare for sowing, and a pusher frame facilitates the movement of the device by the staff.

[0021] In summary, this technical solution specifically discloses a two-stage transmission synchronous soil-laying seeding device, which includes a transmission motor, a transmission shaft, a first bevel gear, a second bevel gear, a soil-covering component, and a soil-pressing component. The transmission motor drives the transmission shaft, which in turn drives the first and second bevel gears to respectively link the soil-covering component and the soil-pressing component, thereby realizing continuous synchronous operation of "sowing-covering-pressing". This ensures that the soil is covered and pressed immediately after sowing, reducing seed exposure time and moisture evaporation, and improving germination rate. Attached Figure Description

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Please see Figures 1-5A dual-stage transmission synchronous soil-laying seeding device includes a support plate 1. Below the support plate 1, from front to back, are arranged a soil-covering component 4 and a soil-pressing component 5. A seeding component 2 is also snapped onto the support plate 1 in front of the soil-covering component 4. The seeding component 2 includes a vertically distributed and interconnected seed storage hopper 21 and a seeding tube 22. A rotating wheel 24 is rotatably snapped onto the seeding tube 22 near its top. Several seeding slots 25 are opened on the circumferential sidewall of the rotating wheel 24. A drive motor 3 is installed on the top surface of the support plate 1. The output shaft of the drive motor 3 is coaxially connected to a drive shaft 31 that passes through and rotatably connects to the support plate 1. A first bevel gear 32 and a second bevel gear 33 are coaxially connected to the bottom end of the drive shaft 31 and to the top of the support plate 1, respectively. The soil-covering component 4 includes two soil-covering discs 42 and a soil-covering bevel gear 41 coaxially connected to one of the soil-covering discs 42 and simultaneously meshing with the first bevel gear 32. The soil-pressing component 5 includes a soil-pressing roller 54.

[0039] In this embodiment, as Figure 1 and Figure 2 As shown, a sowing motor 23 is fixedly installed on the top surface of the support plate 1 on one side of the sowing tube 22. The output shaft of the sowing motor 23 is coaxially connected to the rotating wheel 24. The sowing motor 23 drives the rotating wheel 24 to rotate independently, controlling the sowing rate. The number of seeding troughs 25 is at least three and they are distributed in a ring at equal intervals to ensure that the seeds are evenly distributed and fall quantitatively, thereby improving the sowing accuracy.

[0040] Furthermore, such as Figure 1 As shown, two soil covering frames 11 are fixedly connected to the bottom surface of the support plate 1, and two soil covering discs 42 are rotatably connected to the bottom ends of the two soil covering frames 11 respectively, to ensure the stability of the two soil covering discs 42 during soil covering.

[0041] Furthermore, such as Figure 4 As shown, the two soil-covering discs 42 are at an angle with their openings facing the direction of the sowing tube 22, and the angle range is 30°-60°. The sides of the two soil-covering discs 42 that are close to each other do not touch, which ensures that the soil gathers towards the sowing furrow and avoids interference. The two soil-covering discs 42 are symmetrically distributed about the vertical center line of the sowing tube 22, which ensures that the amount of soil covering both sides of the sowing furrow is uniform, avoids the seeds being exposed or covered too deeply, and ensures that the soil can accurately cover the sowing furrow.

[0042] It is important to note that, such as Figure 4 As shown, the two soil-covering discs 42 are coaxially connected to the opposite sidewalls of each other, and the ends of the two rotating rods 44 that are close to each other are coaxially connected to meshing steering bevel gears 43, so that the two soil-covering discs 42 rotate in the same direction under the drive of the steering bevel gears 43.

[0043] In this embodiment, as Figure 1As shown, a pair of roller frames 12 are fixedly connected to the bottom surface of the support plate 1 at the rear of the soil covering component 4. The soil pressing roller 54 is rotatably engaged between the bottom ends of the two roller frames 12. The soil pressing roller 54 located at the rear of the soil covering component 4 can ensure the stability of soil pressing and the accuracy of the soil covering position.

[0044] Furthermore, such as Figure 5 As shown, the soil compaction assembly 5 also includes a soil compaction bevel gear 51 that meshes with the second bevel gear 33. The roller shaft of the soil compaction bevel gear 51 is rotatably inserted into a support block fixed on the top surface of the support plate 1. The roller shafts of the soil compaction bevel gear 51 and the soil compaction roller 54 are coaxially connected to a transmission wheel 52 on the same side. The two transmission wheels 52 are connected by a transmission belt 53 to realize the transmission of power from the second bevel gear 33 to the transmission wheel 52 and then to the soil compaction roller 54, ensuring that the soil compaction action is synchronized with the overall transmission.

[0045] It is worth mentioning that, such as Figure 1 As shown, a furrow opener 6 is installed on the bottom surface of the support plate 1 in front of the seeding pipe 22. Before sowing, a planting furrow is dug to prepare for sowing. A pusher 7 is fixedly connected to the support plate 1 behind the soil pressing component 5 to facilitate the pusher to move the device to any desired sowing position.

[0046] Finally, it should be noted that the seeding motor 23, transmission motor 3, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0047] Working principle: In this embodiment, the dual-stage transmission synchronous soil-laying seeding device is used by the operator holding the push frame 7 to move the device. The furrow opener 6 first opens the furrow in front. In the seeding component 2, the seeding motor 23 drives the rotating wheel 24 to rotate. The seeds in the seed storage hopper 21 enter the seeding tube 22 through the seed distribution groove 25 on the rotating wheel 24 and then fall into the opened furrow. The transmission motor 3 drives the transmission shaft 31 to rotate. The first bevel gear 32 at the bottom of the transmission shaft 31 meshes with one of the soil covering bevel gears 41 of the soil covering component 4. Then, through two meshing steering bevel gears 43, it drives two symmetrically distributed soil covering discs 42 at an angle of 10°-30° to rotate, pushing the adjacent soil into the furrow after sowing to complete the soil covering. At the same time, the second bevel gear 33 on the transmission shaft 31 meshes with the soil pressing bevel gear 51 of the soil pressing component 5. Through the transmission wheel 52 and the transmission belt 53, it drives the soil pressing roller 54 to rotate, compacting the soil after covering, realizing the synchronous operation of furrow opening, sowing, soil covering and soil pressing.

[0048] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
