[0002] An electric seed metering device is a type of machinery used in agricultural planting, typically in conjunction with a seeder. Its main function is to evenly distribute seeds into the soil at a specified depth and spacing. The electric seed metering device utilizes an electric drive system to control the seed dispensing process, offering high precision and efficiency.

[0003] According to a public announcement (Publication No.: CN 111642194 A), an electrically driven seed metering device, apparatus and method includes a housing and a spiral seed metering wheel assembly and a stirring shaft assembly installed inside the housing. The spiral seed metering wheel assembly and the stirring shaft assembly are connected to a drive device, and under the action of the drive device, the spiral seed metering wheel assembly and the stirring shaft assembly can rotate in the same direction according to a set transmission ratio. A seed cleaning plate is installed at the bottom of the housing. The seed cleaning plate is tightly fitted with the outer edge of the spiral seed metering wheel assembly, and the upper surface of the seed cleaning plate is higher than the lower surface of the spiral seed metering wheel assembly.

[0004] The aforementioned method, which relies on the interaction between components such as the spiral seed metering wheel assembly and the stirring shaft assembly, is insufficient to loosen or move stuck seeds, leading to blockages in the seed metering tube and reduced sowing efficiency. This issue requires improvement. Utility Model Content

[0009] For example, in at least one embodiment of the present invention, an electrically driven seed metering device for planting is provided, which further includes: a spring is fixedly connected to one end of the rack, and the end of the spring away from the rack is fixedly connected to the inner wall of the outer frame. The design of the spring facilitates automatic reset when the rack is not driven and does not move.

[0010] For example, in at least one embodiment of the present invention, an electrically driven seed metering device for planting is provided, which further includes: a plurality of seed metering tubes arranged in a linear array at the bottom of the seed metering device; a cover plate rotatably connected to the top of the storage box; and two rollers, the rollers being designed to drive the entire device to move.

[0011] According to another aspect, at least one embodiment of this utility model also provides an electrically driven seed metering device for planting, comprising: a scraping and cleaning assembly provided on the side of the seed metering device, the scraping and cleaning assembly including a support rod, one end of the support rod being fixedly connected to the side of a support frame, one end of the support rod being fixedly connected to a pressure chamber, one end of the pressure chamber having a push rod first passing through it, one end of the pressure chamber having a push rod second passing through it, the end of the push rod first away from the pressure chamber being fixedly connected to a triangular block, a pressing rod being fixedly connected to the side of the striking rod, one end of the pressing rod being fixedly connected to a trigger block, and one end of the push rod second being rotatably connected to a scraper, the scraper being used to scrape the discharge port of the seed metering tube to prevent soil and other residues from contaminating the seeds.

[0012] For example, in at least one embodiment of the present invention, an electrically driven seed metering device for planting is provided, which further includes: the triangular block and the push rod are located on the displacement trajectory of the squeezing rod and the touch block, the scraper is located on the side of the seed metering tube, and the seed metering tube is located on the displacement trajectory of the scraper. This design is beneficial for driving the scraper to scrape the seed metering tube.

[0013] For example, in at least one embodiment of the present invention, an electrically driven seed metering device for planting is provided, which further includes: a spring two is fixedly connected to the circumferential surface of the push rod one, and the end of the spring two away from the push rod one is fixedly connected to one end of the air pressure chamber.

[0016] The beneficial effects of the embodiments of this utility model are as follows: This invention utilizes the interplay of components such as the seed metering tube, support frame, rack, and striking rod within the seed metering anti-clogging assembly to vibrate the seed metering tube, reducing seed blockage. Seed blockage is common during sowing, affecting sowing efficiency and effectiveness. Vibrating the seed metering tube with the striking rod effectively reduces seed blockage, ensuring smooth seed transport. The vibration loosens or moves stuck seeds, preventing blockages and ensuring the continuity of the seed metering process. This reduces blockages, improves sowing efficiency, lowers manual labor intensity, and increases accuracy.

[0017] In this invention, the cooperation between components such as the air pressure chamber, scraper, limiting rod, and trigger block inside the scraping cleaning assembly enables one-sided rotation, which inserts the limiting rod into the slot, temporarily restricting and locking the position of the scraper. Through electric drive control, the seed metering device can precisely control the movement of the scraper, ensuring the cleanliness of the seed metering port. A clean seed metering port reduces blockage and contamination, thereby improving the efficiency and accuracy of seed dispensing. The design of the limiting rod allows for precise adjustment and locking of the scraper's position, effectively preventing the equipment from affecting the seed dispensing process when not needed.

[0021] The present invention 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 present invention and not intended to limit its scope.

[0027] like Figures 1-5 As shown, an electrically driven seed metering device for planting is provided in one embodiment of the present invention. It includes a seed metering device 1, a storage box 2 fixedly connected to the side of the seed metering device 1, a seed metering anti-blocking component 3 provided at the bottom of the seed metering device 1, the seed metering anti-blocking component 3 including a storage tank 33, one end of the storage tank 33 is located at the top of the seed metering device 1, a seed metering tube 32 passes through the bottom of the seed metering device 1, a connecting rod 36 fixedly connected to the bottom of the storage box 2, an outer shell frame 37 fixedly connected to the side of the connecting rod 36, a short rod 38 fixedly connected to the side of the outer shell frame 37, a motor 39 fixedly connected to one end of the short rod 38, a half gear 310 fixedly connected to the output shaft of the motor 39, a rack 311 slidably connected to the inner wall of the outer shell frame 37, a striking rod 312 fixedly connected to one end of the rack 311, rollers 31 provided on the side of the storage box 2, and a support frame 34 fixedly connected to the side of the seed metering device 1.

[0028] In some examples, the half gear 310 and the rack 311 mesh with each other, the striking rod 312 is located on the side of the seed metering tube 32, and the seed metering tube 32 is located on the displacement trajectory of the striking rod 312. This design is beneficial for striking the seed metering tube 32 when the striking rod 312 moves.

[0029] In some examples, a switch 314 is provided on the surface of the motor 39, and a limit rod 313 is fixedly connected to the side of the rack 311. The end of the limit rod 313 away from the rack 311 is slidably connected to the inner wall of the outer frame 37. The design of the limit rod 313 is beneficial to limit the movement trajectory of the rack 311 and prevent the movement trajectory of the rack 311 from deviating.

[0030] In some examples, one end of the rack 311 is fixedly connected to a spring 315, and the end of the spring 315 away from the rack 311 is fixedly connected to the inner wall of the outer casing 37. The design of the spring 315 is conducive to automatic reset when the rack 311 is not driven and does not move.

[0031] In some examples, there are several seeding tubes 32 arranged in a linear array at the bottom of the seeder 1, and a cover plate 35 is rotatably connected to the top of the storage box 2. Two rollers 31 are provided, and the rollers 31 are designed to drive the entire device to move.

[0032] For example, such as Figures 1-5As shown, the storage box 2 is used to store seeds. It is usually located on the upper part of the seed metering device 1 or on the main unit. As a seed storage space, it is responsible for preparing the seeds for subsequent transportation. The seed metering pipe 32 is a pipe that transports seeds from the storage box 2 to the soil for sowing. It consists of multiple slender pipes and connects the storage box 2 and the seed metering device 1. When the electric drive system starts working, the seeds are transported from the storage box 2 to the soil through the seed metering pipe 32 to achieve sowing. Pressing the switch 314 starts the motor 39. The rotation of the motor 39 drives the half gear 310 to rotate. Half of the teeth on the half gear 310 mesh with the rack 311. When the teeth on the half gear 310 rotate onto the rack 311, they drive the rack 311 to slide on the inner wall of the outer frame 37, causing the rack 311 to strike. The rod 312 slides and moves closer to the seed metering tube 32. The movement of the rack 311 pulls on the spring 315. The seed metering tube 32 is located on the movement trajectory of the striking rod 312. When the striking rod 312 moves, it strikes the outer wall of the seed metering tube 32, causing vibration and reducing the possibility of seeds getting stuck inside the seed metering tube 32. The seed metering tube 32 is easily blocked by seeds during the sowing process, affecting the sowing effect and efficiency. By vibrating the seed metering tube 32 through the striking rod 312, the blockage of seeds in the tube can be effectively reduced, ensuring smooth seed delivery. The vibration can loosen or move stuck seeds, thereby avoiding blockage problems and ensuring the continuity of the seed metering process. This reduces blockage, improves sowing efficiency, reduces manual operation intensity, and improves accuracy.

[0033] like Figures 1-5 As shown, this invention illustrates an electrically driven seed metering device for planting in another embodiment of the present invention, comprising: a scraping and cleaning assembly 4 disposed on the side of the seed metering device 1, the scraping and cleaning assembly 4 including a support rod 41, one end of the support rod 41 being fixedly connected to the side of the support frame 34, a pressure chamber 42 being fixedly connected to one end of the support rod 41, a push rod 43 passing through one end of the pressure chamber 42, a push rod 44 passing through one end of the pressure chamber 42, a triangular block 48 being fixedly connected to the end of the push rod 43 away from the pressure chamber 42, a pressing rod 45 being fixedly connected to the side of the striking rod 312, a trigger block 46 being fixedly connected to one end of the pressing rod 45, and a scraper 47 being rotatably connected to one end of the push rod 44. The scraper 47 is used to scrape the discharge port of the seed metering tube 32 to prevent soil and other residues from contaminating the seeds.

[0034] In some examples, the triangular block 48, the push rod 43 are located on the displacement trajectory of the squeezing rod 45 and the actuating block 46, the scraper 47 is located on the side of the seed metering tube 32, and the seed metering tube 32 is located on the displacement trajectory of the scraper 47. This design is beneficial for driving the scraper 47 to scrape the seed metering tube 32.

[0035] In some examples, a spring 49 is fixedly connected to the circumferential surface of push rod 43. The end of spring 49 away from push rod 43 is fixedly connected to one end of the pressure chamber 42. The design of spring 49 is to allow push rod 43 to automatically reset when it is not compressed.

[0036] In some examples, a spring 410 is fixedly connected to the circumferential surface of push rod 44. The end of spring 410 away from push rod 44 is fixedly connected to one end of the pressure chamber 42. The design of push rod 44 is conducive to the automatic reset of push rod 44 when it is not compressed.

[0037] In some examples, the top of the scraper 47 is rotatably connected to a limiting rod 411, and the top of the pressure chamber 42 is provided with a slot 412, which is located on the displacement trajectory of the limiting rod 411. The design of the limiting rod 411 is beneficial for limiting the position of the scraper 47.

[0038] For example, such as Figures 1-5As shown, the striking rod 312 moves towards the side closer to the seeding tube 32. This movement of the striking rod 312 causes the squeezing rod 45 and the actuating block 46 to move. The triangular block 48 and the push rod 43 are located on the movement trajectory of the squeezing rod 45. When the squeezing rod 45 moves, it squeezes the triangular block 48, causing it to move downwards. This downward movement of the triangular block 48 causes the push rod 44 to move downwards, squeezing it into the pressure chamber 42 and pushing the interior of the pressure chamber 42. The movement of the gas pushes out the push rod 44 at the other end, which in turn pushes out the scraper 47. The scraper 47 is located on the side of the discharge port of the seed metering tube 32. When the scraper 47 moves, it scrapes the discharge port, reducing dust and dirt residue on the discharge port of the seed metering tube 32 and preventing seed contamination. When the scraper 47 is not needed, it rotates along one end of the push rod 44, moving away from the seed metering tube 32, temporarily removing the scraper 47 from the tube to prevent interference with seed metering. When discharging material through pipe 32 and adjusting its position, rotate the limiting rod 411 along one end of the scraper 47, moving the limiting rod 411 towards the side closer to the slot 412. This allows the limiting rod 411 to be inserted into the slot 412, temporarily locking the position of the scraper 47. Through electric drive control, the seed metering device 1 can precisely control the movement of the scraper 47, ensuring a clean seed outlet. A clean seed outlet reduces blockage and contamination, thereby improving the efficiency and accuracy of seed discharging. Because the seed metering device 1 has a scraper 47 cleaning function, it effectively reduces the residue of dust, soil, and other impurities in the seed discharging pipe 32, preventing seed contamination. This is crucial for seed quality during the planting process, especially in agricultural environments with high seed quality requirements. The design of the limiting rod 411 allows for precise adjustment and locking of the scraper 47's position, effectively preventing the equipment from affecting the seed discharging process when not needed. Furthermore, the equipment design considers the needs of different working conditions, enhancing flexibility and adaptability.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
