Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a hard-soft preparation mechanism for a seedbed of a double-seedling belt seeder. Background Technology

[0002] Double-seedling belt seeders are mainly used for sowing crops in agricultural production. The characteristic of double-seedling belt seeders is that they can sow two rows or two rows of crops on one tillage belt at the same time, thereby improving the sowing efficiency of crops. Double-seedling belt seeders are mainly used for sowing crops such as corn, soybeans, and cotton. Current double-seedling belt seeders usually include a sowing device and a soil covering mechanism. Seeds fall into the furrows dug by the furrow opener through a specific sowing device and are covered with soil.

[0003] However, existing double-seedling seeders lack a soil-leveling mechanism during actual sowing operations. This prevents the seeder from evenly dispersing the soil during the sowing process, leading to soil clumping during subsequent covering. This results in the soil not effectively contacting the seeds, affecting the sowing effect and reducing yield. Utility Model Content

[0004] This utility model provides a hard and soft soil preparation mechanism for a double-seedling belt seeder, which can effectively solve the problem mentioned in the background art that existing double-seedling belt seeders, due to the lack of a soil preparation mechanism, cannot evenly disperse the soil during the sowing process. This leads to soil clumping during subsequent covering, preventing effective contact between the soil and seeds, thus affecting the sowing effect and reducing yield.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seedbed hard preparation and soft handling mechanism for a double seedling belt sower, comprising a traction main frame, two connecting side frames symmetrically connected to one end of the traction main frame, an L-shaped connecting bracket detachably connected to the outer side of the ends of the two connecting side frames, a limiting side plate detachably connected to the inner side of the end of the L-shaped connecting bracket, bolts connecting the connecting side frames and the L-shaped connecting bracket, and connecting the L-shaped connecting bracket and the limiting side plate, and a central rotating cylinder rotatably connected between the two connecting side frames;

[0006] The outer two sides of the central rotating cylinder are symmetrically connected to limiting discs, and the inner side of the limiting discs is connected to a soil-forming wheel. The end of the soil-forming wheel is connected to the edge of the limiting disc through an abutment ring seat. Several sets of soil-pulling blocks are evenly connected to the edge of the soil-forming wheel at equal angles.

[0007] Both ends of the central rotating cylinder are fitted with end caps, and a central rotating shaft is fixedly connected to the inner middle of the central rotating cylinder and the end caps. Both ends of the central rotating shaft are rotatably connected to the inner side of the bearing seat, and the bearing seat is embedded in the interior of the connecting seat.

[0008] Preferably, the limiting side plate is inclined, and the edge of the limiting side plate is in contact with the edge of the abutting ring seat.

[0009] Preferably, the central rotating cylinder is rotatably connected to the inner side of the two connecting seats, and both the central rotating cylinder and the end cover are rotatably connected to the bearing seat through the central rotating shaft.

[0010] Preferably, the inner side of the connecting side frame is detachably connected to the connecting seat via a connecting bolt.

[0011] Preferably, a connecting bracket is fixedly connected to the inner middle of the traction main frame, a reinforcing plate is detachably connected to the inner side of the connecting bracket, a connecting plate is connected to the end of the reinforcing plate, and a limit plate is connected to the end of the connecting plate.

[0012] Preferably, the reinforcing plate is located between the two limiting discs on the outer side of the central rotating cylinder, and the limiting plate abuts against the edge of the central rotating cylinder.

[0013] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use.

[0014] 1. The central rotating drum, limiting disc, soil-setting wheel, and abutment ring are connected to the inner side of the side frame, facilitating the synchronous rotation of the central rotating drum and soil-setting wheel during the seeder's movement. The soil-setting wheel, with its evenly spaced soil-dispersing blocks at its edge, disperses the soil, creating planting furrows. This dispersed soil during furrowing ensures better contact between the dispersed soil and seeds when covering them with soil, improving germination rate and guaranteeing higher yields.

[0015] 2. The fixed connection between the connecting side frame and the connecting seat facilitates the quick installation of the soil-forming structure. The rotational connection between the central rotating cylinder, end caps, central rotating shaft, and bearing seat facilitates the flexible rotation of the soil-forming wheel, thereby improving the convenience of the soil-forming wheel rotation process. Furthermore, the traction main frame and connecting side frame facilitate the quick combination and connection of the soil-forming mechanism with the seeder, thereby enabling the seeder to drive the soil-forming wheel to rotate more stably. At the same time, this combination method facilitates the quick disassembly of the overall structure, making it convenient to maintain and replace individual structural components.

[0016] 3. By setting connecting brackets, reinforcing plates, limiting plates, and connecting plates in the middle of the connecting side frame and between the two soil-setting rollers, the entire sorting mechanism has higher structural strength, ensuring stable traction operation of the sorting structure. At the same time, the limiting plates and limiting side plates set on both sides of the two soil-setting rollers facilitate the dispersion of soil to both sides of the soil-setting rollers when the soil-setting rollers are spreading, improving the regularity of the formed sowing furrows and facilitating better subsequent sowing.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Example: Figure 1-6As shown, this utility model provides a technical solution: a hard and soft preparation mechanism for a seedbed of a double-seedling belt seeder, including a traction main frame 1. Two connecting side frames 2 are symmetrically connected to one end of the traction main frame 1. L-shaped connecting brackets 3 are detachably connected to the outer sides of the ends of the two connecting side frames 2. Limiting side plates 4 are detachably connected to the inner sides of the ends of the L-shaped connecting brackets 3. Connecting bolts 5 are used to connect the connecting side frames 2 and the L-shaped connecting brackets 3, and the L-shaped connecting brackets 3 and the limiting side plates 4. A central rotating cylinder 6 is rotatably connected between the two connecting side frames 2.

[0028] The outer two sides of the central rotating cylinder 6 are symmetrically connected to limiting discs 7, and the inner side of the limiting discs 7 is connected to a soil-forming wheel 8. The end of the soil-forming wheel 8 is connected to the edge of the limiting disc 7 through an abutment ring seat 9. The limiting side plate 4 is inclined and the edge of the limiting side plate 4 is in contact with the edge of the abutment ring seat 9, which facilitates the connection of the limiting side plate 4. The limiting side plate 4 can conveniently limit and block the soil that is pushed away by the side of the soil-forming wheel 8. Several sets of soil-pulling blocks 10 are evenly connected at equal angles on the edge of the soil-forming wheel 8.

[0029] Both ends of the central rotating drum 6 are fitted with end caps 11, and the central rotating shaft 12 is fixedly connected to the inner middle of the central rotating drum 6 and the end caps 11. Both ends of the central rotating shaft 12 are rotatably connected to the inner side of the bearing seat 14. The central rotating drum 6 is rotatably connected to the inner side of the two connecting seats 13. The central rotating drum 6 and the end caps 11 are rotatably connected to the bearing seat 14 through the central rotating shaft 12, which facilitates the rotation of the central rotating drum 6. This facilitates the rotation of the limiting disc 7 and the soil-settling wheel 8 through the central rotating drum 6. The bearing seat 14 is embedded in the interior of the connecting seat 13. The inner side of the connecting side frame 2 is detachably connected to the connecting seat 13 through the connecting bolt 5, which facilitates the easy connection and disassembly between the connecting side frame 2 and the connecting seat 13.

[0030] A connecting bracket 15 is fixedly connected to the inner middle of the traction main frame 1. A reinforcing plate 16 is detachably connected to the inner side of the connecting bracket 15. A connecting plate 18 is connected to the end of the reinforcing plate 16, and a limiting plate 17 is connected to the end of the connecting plate 18. The reinforcing plate 16 is located between two limiting discs 7 on the outer side of the central rotating drum 6, and the limiting plate 17 abuts against the edge of the central rotating drum 6. This gives the entire sorting mechanism higher structural strength, ensures stable traction operation of the sorting structure, and facilitates soil interception through the limiting plate 17.

[0031] The working principle and usage process of this utility model: In actual application, the hard and soft seedbed preparation mechanism of the double seedling belt seeder first connects the traction main frame 1 with the traction connecting frame of the double seedling belt seeder. The double seedling belt seeder drives the preparation mechanism to carry out synchronous operation. When the preparation mechanism is actually assembled and connected, the traction main frame 1, the connecting side frame 2, the L-shaped connecting bracket 3 and the limiting side plate 4 are combined and connected by the connecting bolt 5, so that the connection combination has higher connection stability.

[0032] Next, the central rotating shaft 12 and end cap 11 are installed on the inner side of the central rotating cylinder 6, and the bearing seat 14 is installed on the inner side of the connecting seat 13. The end of the central rotating shaft 12 is rotatably connected to the inner side of the bearing seat 14, so that the central rotating cylinder 6 can rotate inside the two connecting seats 13. With the help of the rotational connection between the central rotating cylinder 6, end cap 11, central rotating shaft 12 and bearing seat 14, it is convenient to drive the soil-settling wheel 8 to rotate flexibly, improving the convenience of the soil-settling wheel 8 during rotation. Then, the connecting seats 13 at both ends of the central rotating shaft 12 are fixedly connected to the inner side of the two connecting side frames 2 respectively. After the central rotating cylinder 6 is installed, the reinforcing plate 16 is limited and installed on the side of the traction main frame 1 through the connecting card seat 15, so as to complete the fixed installation of the reinforcing plate 16, its end limiting plate 17 and connecting plate 18, so that the entire sorting mechanism has higher structural strength.

[0033] During the specific sowing and soil preparation process, the seeder will simultaneously drive the central rotating drum 6 and the soil preparation wheel 8 to rotate as it moves. By using the soil-dispersing blocks 10 at the edge of the soil preparation wheel 8, the soil can be broken up by the evenly distributed soil-dispersing blocks 10 during the rotation of the soil preparation wheel 8. This allows the soil to be evenly dispersed to both sides to form sowing furrows. This process of dispersing and spreading the soil during furrowing allows the dispersed soil to better contact the seeds when covering them with soil later, thereby improving the seed germination rate.

[0034] During the soil-moving process of the soil-forming roller 8 and the soil-moving block 10, the limiting plate 17 and the limiting side plate 4 set on both sides of the two soil-forming rollers 8 respectively are used to facilitate the dispersion of the soil to both sides of the soil-forming roller 8 when the soil is being moved by the soil-forming roller 8. This improves the regularity of the formed sowing furrow and facilitates better sowing in the future.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
