Description

Technical Field

[0001] This utility model relates to the field of seeders, and in particular to an electric-driven seeder. Background Technology

[0002] A seeder is a planting machine that uses crop seeds as the object of sowing. Seeders used for a certain type or type of crop are often named after the crop type, such as grain strip seeder, corn hill seeder, cotton seeder, and pasture broadcaster. They are mainly driven by an electric motor to rotate a fan, which then sucks in the seeds and sows them.

[0003] Current seeders integrate multiple seed boxes for seed dispensing. However, traditional seed boxes use a threaded locking connection, which is time-consuming to disassemble and assemble when damaged or under maintenance. Furthermore, the planar positioning structure is prone to displacement under vibration conditions and cannot provide stable positioning. To address these issues, we propose an electrically driven seeder. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electrically driven seeder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric-driven seeder includes a support frame with multiple seed boxes evenly spaced through it. A moving mechanism is provided on one side of each seed box and is fixed to the support frame by a locking mechanism. A connecting arm is rotatably connected to one end of the moving mechanism. A limit mechanism is connected to the upper end of the connecting arm, and a clamping mechanism is rotatably connected to one end of the connecting arm. One end of the clamping mechanism clamps one side of the seed box.

[0007] Preferably, the moving mechanism includes a fixed tube disposed on one side of the seed box, a stud threaded into the fixed tube, a rotating wheel fixed to one end of the stud, a moving block rotatably connected to the end of the stud away from the rotating wheel, a push rod fixed to one end of the moving block, and the push rod passing through the side wall of the fixed tube and rotatably connected to the middle of the connecting arm.

[0008] Preferably, the locking mechanism includes clamps sleeved on both ends of the fixed tube, and the two clamps are installed on the support frame by two screws.

[0009] Preferably, the limiting mechanism includes a rotating arm rotatably connected to one side of the upper end of the connecting arm, a fixing member rotatably connected to one end of the rotating arm, a fixing plate fixedly fitted to one end of the fixing tube, the fixing member being fixed to the upper end of the fixing plate, and the push rod penetrating the fixing plate.

[0010] Preferably, the clamping mechanism includes a connecting block rotatably connected to one end of the connecting arm, a clamping plate fixed to one end of the connecting block, and insertion rods fixed to the four corners of one side of the clamping plate.

[0011] Preferably, the seed box has a slot on one side, and each of the four corners of the slot has a positioning hole, into which the four rods are inserted.

[0012] In this invention, when the seed box needs to be installed, it is installed through the support frame, with one end abutting against one side of the support frame. Then, the rotating wheel drives the stud to rotate, thereby driving the moving block and push rod to move. The movement of the push rod drives the connecting arm and clamping plate to move forward, so that the clamping plate is engaged in the slot and the insertion rod is engaged in the positioning hole. Through the clamping and squeezing at four points, the seed box is firmly fixed. When disassembly is required, the reverse rotating wheel drives the connecting arm to rotate and bring out the clamping plate.

[0013] This utility model has the following advantages:

[0014] 1. Compared with the traditional threaded locking connection, the seed box can be installed and disassembled simply by rotating the wheel, which greatly saves time and improves work efficiency;

[0015] 2. The use of four insertion rods and positioning holes enables precise positioning of four points, effectively preventing the seed box from shifting under vibration conditions. Compared with the traditional planar positioning structure, its stability is significantly improved, ensuring the stable installation of the seed box during the operation of the seeder and facilitating the smooth progress of the sowing operation.

[0016] 3. The operation of rotating the wheel is simple and easy to understand. It does not require operators to have professional skills and knowledge. Whether installing or disassembling the seed box, operators can easily complete the task, reducing labor intensity and improving the convenience of operation.

[0017] In summary, this invention allows for quick disassembly and installation, reducing equipment downtime and ensuring agricultural production progress. It also prevents seed box displacement under vibration conditions, significantly improving stability. Furthermore, it is simple and convenient to operate, reducing labor intensity.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-7 An electric-driven seeder includes a support frame 14 with multiple seed boxes 13 evenly spaced along the support frame 14. Each seed box has a volume of 800L. A moving mechanism is provided on one side of the seed box 13, and the moving mechanism is fixed to the support frame 14 by a locking mechanism. A connecting arm 2 is rotatably connected to one end of the moving mechanism. A limit mechanism is connected to the upper end of the connecting arm 2, and a clamping mechanism is rotatably connected to one end of the connecting arm 2. One end of the clamping mechanism clamps one side of the seed box 13. By rationally designing the moving mechanism, locking mechanism, limit mechanism, and clamping mechanism, the seed box 13 can be easily installed and disassembled, providing convenience for the use and maintenance of the seeder.

[0028] The moving mechanism includes a fixed tube 10 located on one side of the seed box 13. The fixed tube is made of high-strength steel pipe with a wall thickness ≥3mm. Its internal thread matches a stud, and the stud's stroke range is 10-30cm. A stud 5 is screwed into the internal thread of the fixed tube 10. A rotating wheel 11 is fixed to one end of the stud 5. A moving block 15 is rotatably connected to the end of the stud 5 away from the rotating wheel 11. A push rod 7 is fixed to one end of the moving block 15. The push rod 7 passes through the side wall of the fixed tube 10 and is rotatably connected to the middle of the connecting arm 2. The fixed tube 10, located on one side of the seed box 13, provides a stable support and motion guidance space for the entire moving mechanism. The stud 5 is screwed into the fixed tube 10. When the rotating wheel 11 rotates, the stud... The stud 5 is threaded into the fixed tube 10, and the stud 5 will move linearly inside the fixed tube 10. The rotating wheel 11 is fixed to one end of the stud 5 and its function is to provide power input for the rotation of the stud 5. The operator can manually rotate the rotating wheel 11 to control the rotation direction and number of turns of the stud 5, thereby precisely controlling the moving distance of the moving block 15 and the push rod 7. The moving block 15 is rotatably connected to the end of the stud 5 away from the rotating wheel 11. It will move synchronously with the linear movement of the stud 5. The push rod 7 is fixed to one end of the moving block 15 and passes through the side wall of the fixed tube 10. Its other end is rotatably connected to the middle of the connecting arm 2. When the moving block 15 moves, the push rod 7 will push the connecting arm 2 to rotate around its rotation point.

[0029] The locking mechanism includes clamps 9 sleeved on both ends of the fixed tube 10, and the two clamps 9 are installed on the support frame 14 by two screws 12. The clamps 9 can firmly fix the fixed tube 10 on the support frame 14, preventing the fixed tube 10 from shifting or shaking due to vibration or other external forces during the operation of the seeder, thereby ensuring the normal operation of the moving mechanism.

[0030] The limiting mechanism includes a rotating arm 3 rotatably connected to one side of the upper end of the connecting arm 2. A fixing member 4 is rotatably connected to one end of the rotating arm 3. A fixing plate 8 is fixedly fitted to one end of the fixing tube 10. The fixing member 4 is fixed to the upper end of the fixing plate 8. The push rod 7 passes through the fixing plate 8. When the connecting arm 2 rotates, the rotating arm 3 will rotate with the connecting arm 2. Since the fixing member 4 is fixed on the fixing plate 8, the rotation range of the rotating arm 3 will be limited to a certain extent, thereby effectively constraining the rotation range of the connecting arm 2 and preventing the connecting arm 2 from rotating excessively and affecting the clamping and fixing effect on the seed box 13.

[0031] The clamping mechanism includes a connecting block 16 rotatably connected to one end of the connecting arm 2. A clamping plate 6 is fixed to one end of the connecting block 16. Insert rods 1 are fixed to the four corners of one side of the clamping plate 6. A slot 17 is provided on one side of the seed box 13. Positioning holes 18 are provided at the four corners of the slot 17. The four insert rods 1 are inserted into the four positioning holes 18. When the clamping plate 6 approaches the seed box 13, the four insert rods 1 will be accurately inserted into the four positioning holes 18. Through the four-point positioning method, combined with the squeezing of the seed box 13 by the clamping plate 6, the seed box 13 can be firmly fixed.

[0032] In this utility model, when the seed box 13 needs to be installed, it is installed through the support frame 14, with one end abutting against one side of the support frame 14. Then, the rotating wheel 11 drives the stud 5 to rotate, thereby driving the moving block 15 and the push rod 7 to move. The movement of the push rod 7 drives the connecting arm 2 and the clamping plate 6 to move forward, so that the clamping plate 6 is engaged in the slot 17 and the insertion rod 1 is engaged in the positioning hole 18. Through the clamping and squeezing at four points, the seed box 13 is firmly fixed. When disassembly is required, the rotating wheel 11 is reversed to drive the connecting arm 2 to rotate and bring out the clamping plate 6.

[0033] In this utility model, when the seed box 13 needs to be disassembled, the operator rotates the rotating wheel 11 in the opposite direction. The reverse rotation of the rotating wheel 11 drives the stud 5 to rotate in the opposite direction inside the fixed tube 10. The stud 5 will move backward in a straight line inside the fixed tube 10, thereby driving the moving block 15 and the push rod 7 to move backward. The backward movement of the push rod 7 will pull the connecting arm 2 to rotate backward around its rotation point. The rotation of the connecting arm 2 will cause the connecting block 16 and the clamping plate 6 to move backward, finally pulling the clamping plate 6 out of the slot 17 of the seed box 13. The four insert rods 1 are also pulled out from the positioning hole 18. At this time, the seed box 13 is no longer fixed by the clamping mechanism, and the operator can easily remove the seed box 13 from the support frame 14 to complete the disassembly of the seed box 13.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
