Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and more specifically, to an electric-driven seeder. Background Technology

[0002] In agricultural production, seeders need to be constantly adapted to different terrains and crop planting conditions. When the terrain of the crop planting area changes, different types of furrowing blocks may need to be replaced to adapt to different soil conditions and crop requirements. In the current technology, the furrowing blocks of seeders are usually fixed, which makes it difficult to quickly replace or adjust the furrowing blocks during use. The traditional fixed installation method is not only time-consuming and labor-intensive, but also increases the labor intensity of farmers and affects the efficiency of sowing operations. Especially when facing large areas of fields, frequent replacement of furrowing blocks further restricts the smoothness of operations and production efficiency. Utility Model Content

The discharge pipe is located at the bottom of the seed box. The quick-release mechanism includes a mounting plate, a fixing sleeve, a plug rod, a guide sleeve, a sliding rod, a locking block, a push spring, a locking groove, and a quick-release mechanism. The mounting plate is fixed on the support frame. The fixing sleeve is installed on the top surface of the mounting plate. The plug rod is installed on the top surface of the furrow block. Multiple sets of guide sleeves are installed inside the fixing sleeve. The sliding rod slides in multiple sets of guide sleeves. The locking block is installed at the bottom of multiple sets of sliding rods. The push spring is installed on the outer wall of multiple sets of locking blocks and connected to the guide sleeve. Multiple sets of locking grooves are distributed on the outer wall of the plug rod.

[0007] This invention further comprises a quick-release mechanism including a sliding groove, a sliding sleeve, an unlocking block, an abutment block, and an mounting sleeve. Multiple sets of sliding grooves are distributed on the outer wall of the fixed sleeve, and the sliding grooves slide within these multiple sets. Multiple sets of unlocking blocks are installed on the inner side of the sliding sleeve. The abutment blocks are located on the top surface of the multiple sets of locking blocks, and the mounting sleeve is fixed to the outer wall of the sliding sleeve.

The cooperation between the sliding groove and the sliding sleeve makes the disassembly process smoother, and the design of the unlocking block simplifies the disassembly process, improving replacement speed and work efficiency, and greatly reducing manual operation time.

[0008] This utility model is further configured such that the mounting sleeve is provided with a limiting mechanism. The limiting mechanism includes a limiting rod, a rotating sleeve, an arc-shaped rod, a mating hole, and a tension spring. Multiple sets of limiting rods are distributed on the bottom surface of the mounting sleeve. The rotating sleeve is rotatably mounted on the outer wall of the fixed sleeve. Multiple sets of arc-shaped rods are mounted on the outer wall of the rotating sleeve. Multiple sets of mating holes are distributed at the bottom ends of multiple sets of limiting rods. Multiple sets of tension springs are provided, with their two ends respectively connected to the fixed sleeve and the mounting sleeve. The limiting mechanism ensures that the mounting sleeve can be stably held in a designated position through the combination of the limiting rod and the rotating sleeve. The cooperation between the arc-shaped rod and the mating hole precisely controls the limiting position, and the tension spring provides the necessary elasticity, ensuring smooth limiting operation, increasing the operating accuracy and stability of the equipment, and preventing changes in the equipment position during operation.

[0009] The present invention is further configured such that a pressure roller is rotatably mounted on one end of the support frame. The pressure roller helps the support frame to maintain good contact with the ground during use, ensuring the stability of the entire seeder. At the same time, the pressure roller can also apply a certain pressure to the soil during movement, which helps the furrow blocks penetrate deeper into the soil, providing better furrowing effect and improving the accuracy and efficiency of sowing.

[0010] The present invention is further provided that a handle is installed at the top of the support frame, and two sets of handles are provided. The handle design makes the equipment easier to operate, especially when it is necessary to adjust or move the equipment. The two sets of handles provide more support points, increase the stability and flexibility of operation, facilitate users to make precise control and adjustment in the field, and improve the convenience and operability of the equipment.

[0011] This utility model is further configured such that the outer wall of the insertion rod is provided with a positioning strip, and the inner wall of the fixing sleeve is provided with a positioning groove. Multiple sets of positioning strips and positioning grooves are provided and slidably connected. The cooperation between the positioning strips and positioning grooves ensures that the insertion rod can be accurately inserted into the fixing sleeve. The multiple sets of positioning strips and positioning grooves ensure the stable fixing of the insertion rod, preventing it from shifting during use and guaranteeing the efficiency and stability of the equipment during operation.

[0012] This invention is further configured such that the outer wall of the insertion rod is provided with a movable groove, and multiple sets of unlocking blocks slide within these grooves. The design of the movable groove and unlocking blocks makes unlocking the insertion rod smoother. The unlocking blocks, through the cooperation of the sliding movable groove, can precisely control the unlocking operation of the insertion rod, reducing friction and jamming during operation and improving the efficiency of disassembling and replacing the grooved blocks.

[0013] This invention is further configured such that each of the multiple sets of sliding rods is a polygonal shape and slidably connected to the multiple sets of guide sleeves. The polygonal design of the sliding rods and guide sleeves ensures precise sliding of the sliding rods within the guide sleeves, reducing jamming caused by uneven sliding. At the same time, the polygonal design enhances the stability of the sliding rods, enabling the device to maintain better stability during operation, further improving the working efficiency and accuracy of the equipment.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an electrically driven seeder, which has the following beneficial effects:

[0016] 1. The design of the sowing mechanism, through precise coordination, makes the sowing process more efficient and accurate. First, the forward wheel drives the entire device forward, pushing the support frame across the land to ensure that the furrowing block can accurately dig shallow furrows, providing an ideal foundation for seed sowing. The combination of the motor-driven rotating wheel and the seed guide hopper ensures that the seeds are evenly distributed in the sowing box and sown into the pre-dug furrows through the discharge pipe, resulting in uniform seed distribution and optimal sowing effect. This design not only ensures uniform seed sowing but also improves sowing efficiency, adapts to the needs of large-scale farmland operations, reduces the complexity of manual operation, and significantly improves the accuracy and speed of the operation.

[0017] 2. The quick-installation mechanism greatly simplifies the installation and replacement process of the trenching block. Through the cooperation of the insertion rod and the fixing sleeve, the quick-installation mechanism can quickly fix the trenching block on the support frame, and provides convenient disassembly function through components such as the sliding sleeve and the unlocking block. This allows users to quickly replace the trenching block when needed, avoiding tedious disassembly work. The cooperation of the locking block, sliding rod and push spring ensures that the locking groove can firmly fix the trenching block, ensuring the stability and firmness of the trenching block. The unlocking block simplifies the disassembly process, improves work efficiency and convenience. Through this simple structure, operators can quickly perform equipment maintenance or replacement, ensuring that the work is not disturbed.

[0018] 3. The limit mechanism ensures the stability and safety of the device during operation. The combination of the limit rod, rotating sleeve, and arc rod provides precise limiting function. When the mounting sleeve needs to be adjusted, the design of the tension spring and arc rod ensures that the mounting sleeve is always kept in the correct position, thereby avoiding displacement or instability of the equipment during operation. The limit mechanism can release the limit on the mounting sleeve when needed, and precisely lock the limit rod by rotating the arc rod through the rotating sleeve during reinstallation, ensuring that the mounting sleeve of the equipment can be firmly fixed and avoiding misoperation or improper installation. This design improves the accuracy and stability of the device and ensures the efficiency and safety of the whole machine during operation. Attached Figure Description

[0028] Please see Figures 1-5 An electrically driven seeder includes a support frame 1, on which a seeding mechanism is mounted. The seeding mechanism includes a forward wheel 2, a furrowing block 3, a hopper 4, a seed box 5, a motor 6, a drive rod 7, a rotating wheel 8, a seed guide hopper 9, and a discharge pipe 10. The forward wheel 2 is rotatably mounted on one end of the support frame 1. The furrowing block 3 is mounted on the support frame 1 via a quick-release mechanism. The hopper 4 is mounted on the support frame 1. The seed box 5 is connected to the bottom end of the hopper 4. The motor 6 is mounted on one side of the support frame 1. The drive rod 7 rotates on the support frame 1 and is connected to the output end of the motor 6. The rotating wheel 8 rotates inside the seed box 5 and is connected to the drive rod 7. The seed guide hopper 9 has multiple sets mounted on the rotating wheel 8. On the outside, the discharge pipe 10 is set at the bottom of the seeding box 5. The quick-installation mechanism includes an installation plate 11, a fixing sleeve 12, an insertion rod 13, a guide sleeve 14, a sliding rod 15, a locking block 16, a push spring 17, a locking groove 18, and a quick-release mechanism. The installation plate 11 is fixed on the support frame 1. The fixing sleeve 12 is installed on the top surface of the installation plate 11. The insertion rod 13 is installed on the top surface of the furrowing block 3. The guide sleeve 14 is provided with multiple sets installed inside the fixing sleeve 12. The sliding rod 15 slides in multiple sets of guide sleeves 14. The locking block 16 is installed at the bottom of multiple sets of sliding rods 15. The push spring 17 is installed on the outer wall of multiple sets of locking blocks 16 and connected to the guide sleeve 14. The locking groove 18 is provided with multiple sets distributed on the outer wall of the insertion rod 13.

[0029] The quick-release mechanism includes a slide groove 19, a sliding sleeve 20, an unlocking block 21, an abutment block 22, and an installation sleeve 23. Multiple sets of slide grooves 19 are distributed on the outer wall of the fixed sleeve 12, and the slide grooves 19 slide within these multiple sets. Multiple sets of unlocking blocks 21 are installed inside the sliding sleeve 20. The abutment blocks 22 are located on the top surface of multiple sets of locking blocks 16. The installation sleeve 23 is fixed to the outer wall of the sliding sleeve 20. This design, through the cooperation of the slide grooves 19 and the sliding sleeve 20, allows for quick disassembly and installation of the trenching block. The synergistic effect of the unlocking block 21 and the abutment block 22 ensures that the locking block 16 can be quickly released, releasing the insertion rod 13, thereby achieving rapid replacement of the trenching block, improving operational efficiency and convenience, and reducing manual operation time.

[0030] A pressure roller 29 is rotatably mounted on one end of the support frame 1. The pressure roller 29 helps the seeder maintain stable contact with the ground during operation, providing stable support. At the same time, the pressure roller 29 helps the furrowing blocks to be inserted deeply into the soil, ensuring the uniformity of the furrowing effect, thereby improving the accuracy and efficiency of sowing.

[0031] A handle 30 is installed at the top of the support frame 1, and there are two sets of handles 30. The handles 30 provide convenient operating fulcrums. Especially when it is necessary to adjust or move the seeder, the two sets of handles can distribute the operating force, improve the stability and flexibility of control, and make it easier for the operator to operate the equipment, thus improving the convenience of operation.

[0032] The outer wall of the insertion rod 13 is provided with a positioning strip 31, and the inner wall of the fixing sleeve 12 is provided with a positioning groove 32. Multiple sets of positioning strips 31 and positioning grooves 32 are provided and are slidably connected. The cooperation between the positioning strips 31 and positioning grooves 32 ensures that the insertion rod 13 can be accurately inserted into the fixing sleeve 12 and remain stable, avoiding the displacement of the insertion rod during use, ensuring the precise connection between the grooved block and the support frame, and increasing the stability and reliability of the equipment during operation.

[0033] The outer wall of the insertion rod 13 is provided with a movable groove 33, and multiple sets of unlocking blocks 21 slide within the multiple sets of movable grooves 33. The cooperation between the movable groove 33 and the unlocking block 21 ensures that the insertion rod 13 can be unlocked smoothly, and by sliding, the unlocking block 21 can precisely control the unlocking process of the insertion rod, avoiding jamming and improving the efficiency and convenience of replacing the grooved block.

[0034] Multiple sets of slide rods 15 are all designed as polygons and slidably connected to multiple sets of guide sleeves 14. The combination of the polygonal design of the slide rods 15 and the guide sleeves 14 ensures that the slide rods are more stable during sliding, reduces jamming caused by uneven sliding, and enhances the stability of the slide rods, making the whole machine run more accurately and ensuring the efficiency and stability of the sowing process.

[0035] In this embodiment, seeds are stored in hopper 4. The support frame 1 is pushed by handle 30, and the support frame 1 moves on the ground via the forward wheel 2 and pressure roller 29. During the movement of the support frame 1, the furrowing block 3 is inserted into the soil to create shallow furrows on the ground. Motor 6 drives the drive rod 7 connected to the support frame 1 to rotate, which in turn drives the rotating wheel 8 to rotate. The rotation of the rotating wheel 8 causes the seed guide hopper 9 to rotate continuously outside the rotating wheel 8, and the seeds are evenly sown into the furrows through the discharge pipe 10. However, when the furrowing block 3 needs to be replaced, the limiting mechanism is released from limiting the sliding sleeve 20. Multiple sets of tension springs 28 pull the mounting sleeve 23, which drives the sliding sleeve 20 to slide along the sliding groove 19. The sliding sleeve 20 pushes multiple sets of unlocking blocks 21 to slide in the movable groove 33 and abut against multiple sets of abutting blocks 22. The multiple sets of unlocking blocks 21 respectively push the multiple sets of abutting blocks 22 to drive the locking block 16. Moving outward, multiple sets of locking blocks 16 slide along the guide sleeve 14 via the slide rod 15 and press against the push spring 17. All sets of locking blocks 16 disengage from the slot 18, thereby releasing the locking of the insertion rod 13. Then, the insertion rod 13 is pulled out of the fixing sleeve 12 to complete the disassembly of the grooved block 3. When a new grooved block 3 needs to be installed, the insertion rod 13 is inserted into the fixing sleeve 12. Multiple sets of positioning strips 31 and positioning grooves 32 are used to position and insert the insertion rod 13. After the insertion rod 13 is fully inserted into the fixing sleeve 12, the mounting sleeve 23 is slid upward and the multiple sets of tension springs 28 are stretched. The mounting sleeve 23 drives the slide sleeve 20 to slide along the slide groove 19. The slide sleeve 20 drives the multiple sets of unlocking blocks 21 to release the abutment of the multiple sets of abutment blocks 22. Thus, the multiple sets of push springs 17 push the locking block 16 to engage in the slot 18. Then, the limiting mechanism limits the mounting sleeve 23 to complete the installation of the grooved block 3.

[0036] Please see Figures 4-5 As one implementation of the limiting mechanism: the mounting sleeve 23 is provided with a limiting mechanism, which includes a limiting rod 24, a rotating sleeve 25, an arc-shaped rod 26, a mating hole 27, and a tension spring 28. Multiple sets of limiting rods 24 are distributed on the bottom surface of the mounting sleeve 23. The rotating sleeve 25 is rotatably mounted on the outer wall of the fixed sleeve 12. Multiple sets of arc-shaped rods 26 are installed on the outer wall of the rotating sleeve 25. Multiple sets of mating holes 27 are distributed at the bottom ends of multiple sets of limiting rods 24. Multiple sets of tension springs 28 are provided, and their two ends are respectively connected to the fixed sleeve 12 and the mounting sleeve 23.

[0037] More specifically, rotating the rotating sleeve 25 drives multiple sets of arc-shaped rods 26 to rotate. The multiple sets of arc-shaped rods 26 move and slide out of the mating holes 27, thereby releasing the restriction on the multiple sets of limiting rods 24 and the installation sleeve 23. However, when it is necessary to limit the installation sleeve 23, the installation sleeve 23 pushes the multiple sets of limiting rods 24 downward. When the mating holes 27 on the multiple sets of limiting rods 24 move to be parallel to the multiple sets of arc-shaped rods 26, rotating the rotating sleeve 25 drives the multiple sets of arc-shaped rods 26 to rotate and insert into the mating holes 27, thereby limiting the multiple sets of limiting rods 24 and simultaneously limiting the installation sleeve 23.

[0038] In summary, during the use or operation of the overall equipment: seeds are stored in the hopper 4, and the support frame 1 is pushed by the handle 30. The support frame 1 moves on the ground via the forward wheel 2 and the pressure roller 29. During the movement of the support frame 1, the furrowing block 3 is inserted into the soil to create shallow furrows on the ground. The motor 6 drives the drive rod 7 connected to the support frame 1 to rotate, which in turn drives the rotating wheel 8 to rotate. The rotation of the rotating wheel 8 causes the seed guide hopper 9 to rotate continuously outside the rotating wheel 8, and the seeds are evenly sown into the furrows through the discharge pipe 10. However, when it is necessary to replace the furrowing block 3, the limiting mechanism is released from the limiting of the sliding sleeve 20. The mounting sleeve 23 is pulled by multiple sets of tension springs 28. The mounting sleeve 23 drives the sliding sleeve 20 to slide along the sliding groove 19. The sliding sleeve 20 pushes multiple sets of unlocking blocks 21 to slide in the movable groove 33 and abut against multiple sets of abutting blocks 22. The multiple sets of unlocking blocks 21 push the multiple sets of abutting blocks 22 respectively. The movable locking block 16 moves outward, and multiple sets of locking blocks 16 slide along the guide sleeve 14 via the slide rod 15 and press against the push spring 17. All sets of locking blocks 16 disengage from the locking groove 18, thereby releasing the locking of the insertion rod 13. Then, the insertion rod 13 is pulled out of the fixing sleeve 12 to complete the disassembly of the grooved block 3. When a new grooved block 3 needs to be installed, the insertion rod 13 is inserted into the fixing sleeve 12, and the insertion rod 13 is positioned by multiple sets of positioning strips 31 and positioning grooves 32. The insertion is performed by positioning and plugging. After the insertion rod 13 is fully inserted into the fixed sleeve 12, the mounting sleeve 23 slides upward and stretches multiple sets of tension springs 28. The mounting sleeve 23 drives the sliding sleeve 20 to slide along the sliding groove 19. The sliding sleeve 20 drives multiple sets of unlocking blocks 21 to release the abutment of multiple sets of abutment blocks 22. Thus, multiple sets of push springs 17 push the locking block 16 to engage in the locking groove 18. Then, the limiting mechanism limits the mounting sleeve 23 to complete the installation of the grooved block 3.

[0039] Rotating the rotating sleeve 25 drives multiple sets of arc-shaped rods 26 to rotate. The multiple sets of arc-shaped rods 26 move and slide out of the mating holes 27, which releases the restriction on the multiple sets of limiting rods 24 and the installation sleeve 23. However, when it is necessary to limit the installation sleeve 23, the installation sleeve 23 pushes the multiple sets of limiting rods 24 downward. When the mating holes 27 on the multiple sets of limiting rods 24 move to be parallel to the multiple sets of arc-shaped rods 26, rotating the rotating sleeve 25 drives the multiple sets of arc-shaped rods 26 to rotate and insert into the mating holes 27, which can limit the multiple sets of limiting rods 24 and simultaneously limit the installation sleeve 23.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
