Description

Technical Field

[0001] This utility model belongs to the field of seeder technology, and in particular relates to a seeder soil covering and compaction device. Background Technology

[0002] The soil compactor is an important component of a seeder. Its main function is to cover the seeds with soil after sowing and compact it appropriately, ensuring close contact between the seeds and the soil, thereby improving the germination rate. The soil compactor typically consists of several cover plates, compaction rollers, and other components. By adjusting the pressure of the compaction rollers or the angle of the cover plates, it can provide suitable compaction effects under different soil conditions, preventing seeds from being buried too deep or too shallow, thus ensuring that the seeds germinate and take root in the optimal environment.

[0003] Current technology typically uses scrapers for scraping operations. However, when compacting in clay soil environments, a certain amount of clay may adhere to the scraper surface, which affects the scraper's working efficiency and makes the subsequent cleaning process more difficult. Due to the strong adhesion of clay, the accumulated soil on the scraper surface may hinder its normal operation, thereby weakening the cleaning effect of the equipment.

[0004] Based on this, this utility model designs a soil compactor for a seeder to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem that current technologies typically use scrapers for scraping operations, but when compacting in clay soil environments, a certain amount of clay may adhere to the scraper surface, affecting the scraper's working efficiency and making subsequent cleaning more difficult. Due to the strong adhesion of clay, the accumulated soil on the scraper surface may hinder its normal operation, thereby weakening the cleaning effect of the equipment. Therefore, this invention proposes a soil compactor for seeders.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soil compactor for a seeder includes a mounting rod, a compactor body installed inside the mounting rod, a protective shell covering the mounting rod, a cleaning device for cleaning the compactor body fixedly connected to one side of the protective shell, and a swinging device for cleaning clay fixedly connected outside the cleaning device.

[0008] As a further description of the above technical solution:

[0009] The cleaning device includes a connecting plate, which is fixedly connected to one side of the protective shell. The connecting plate has several rectangular grooves, and a fixed shaft is fixedly connected in the rectangular grooves. A rotating plate is fitted over the fixed shaft, and a scraper is fixedly connected to the outside of the rotating plate. Two coil springs are fitted over the fixed shaft.

[0010] As a further description of the above technical solution:

[0011] The rotating plate and the fixed shaft form a rotating connection.

[0012] As a further description of the above technical solution:

[0013] One end of the coil spring is fixedly connected to the outside of the rotating plate, and the other end of the coil spring is fixedly connected to the inside of the rectangular groove.

[0014] As a further description of the above technical solution:

[0015] The scraper is mounted on the outside of the press body, and the contact surface with the press body is set in a triangular shape to facilitate scraping and cleaning.

[0016] As a further description of the above technical solution:

[0017] The swinging device includes a drive motor and two frames. The drive motor is fixedly connected inside the connecting plate, and a cam is fixedly connected to the output end of the drive motor. The two frames are symmetrically installed on one side of the connecting plate, and a pressing plate is slidably connected inside the frames.

[0018] As a further description of the above technical solution:

[0019] The extrusion surface of the extrusion plate is set as an arc-shaped surface, and the arc-shaped surface overlaps with the cam. The extrusion plate overlaps with the rotating plate.

[0020] As a further description of the above technical solution:

[0021] The length and width of the extrusion plate are slightly smaller than the length and width of the frame body, and the two are closely fitted together.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] 1. In this utility model, when clay adheres to the outer surface of the purifier body, the coil spring applies elastic force to drive the rotating plate to rotate, thereby driving the scraper to perform preliminary cleaning on the surface of the purifier body. At the same time, the drive motor starts and drives the cam to rotate. The rotation of the cam applies pressure to the extrusion plate, causing the extrusion plate to slide along the slide rail in the frame. The thrust generated by the extrusion plate during the sliding process acts on multiple rotating plates, causing the rotating plates and scrapers to rotate synchronously. Subsequently, when the cam moves away from the extrusion plate, the coil spring returns to its initial state and applies a reverse elastic force to the rotating plate, quickly driving the rotating plate and scraper to reset. At this time, the rapid reset of the rotating plate and scraper and the resulting vibration will shake off the clay adhering to the surface, ultimately achieving a thorough cleaning of the purifier body and removing the adhering clay.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5 ,

[0033] This utility model provides a technical solution: a soil compactor for a seeder, including a mounting rod 1, a compactor body 2 installed inside the mounting rod 1, a protective shell 3 covering the mounting rod 1, a cleaning device 4 for cleaning the compactor body 2 fixedly connected to one side of the protective shell 3, and a swinging device 5 for cleaning clay fixedly connected to the outside of the cleaning device 4.

[0034] Specifically, such as Figures 2-5 As shown, the cleaning device 4 includes a connecting plate 41, which is fixedly connected to one side of the protective shell 3. Several rectangular grooves 42 are opened in the connecting plate 41. A fixed shaft 43 is fixedly connected in the rectangular grooves 42. A rotating plate 44 is sleeved on the fixed shaft 43. A scraper 45 is fixedly connected to the outside of the rotating plate 44. Two coil springs 46 are sleeved on the fixed shaft 43. A rotatable connection is formed between the rotating plate 44 and the fixed shaft 43. One end of the coil spring 46 is fixedly connected to the outside of the rotating plate 44, and the other end of the coil spring 46 is fixedly connected to the rectangular grooves 42. The rotatable connection between the rotating plate 44 and the fixed shaft 43 ensures that the rotating plate 44 can rotate within a certain range, enabling flexible cleaning operations. At the same time, the elasticity of the coil spring 46 allows the rotating plate 44 to quickly return to its original position under external force. This structural design not only improves cleaning efficiency but also avoids long-term wear of mechanical parts through elastic recovery, thereby extending its service life.

[0035] The scraper 45 is mounted on the outside of the compressor body 2, and the contact surface with the compressor body 2 is set in a triangular shape to facilitate scraping and cleaning. The triangular contact surface has a strong scraping effect during the cleaning process, which can more effectively remove the clay or debris attached to the surface of the compressor body 2. In addition, the triangular scraping edge allows the scraper 45 to adapt to different soil conditions when in contact with the surface, providing a more refined cleaning effect.

[0036] The swing device 5 includes a drive motor 51 and two frames 53. The drive motor 51 is fixedly connected inside the connecting plate 41, and a cam 52 is fixedly connected to the output end of the drive motor 51. The two frames 53 are symmetrically installed on one side of the connecting plate 41. A pressing plate 54 is slidably connected inside the frame 53. The pressing surface of the pressing plate 54 is set as an arc surface, and the arc surface overlaps with the cam 52. The pressing plate 54 overlaps with the rotating plate 44. The length and width of the pressing plate 54 are slightly smaller than the length and width inside the frame 53, and the two fit tightly together. The pressing surface of the pressing plate 54 slidably connected inside the frame 53 is set as an arc surface, which can better fit with the cam 52 and provide a stable force state. This arc design allows the pressing plate 54 to apply pressure evenly during the contact process with the rotating plate 44, avoiding the impact of uneven force distribution on the cleaning effect. At the same time, the arc surface design allows the pressing plate 54 to adapt to different soil densities and friction, further improving the stability and efficiency of the cleaning effect.

[0037] Working principle, in use: When clay adheres to the outer surface of the purifier body 2, the coil spring 46 drives the rotating plate 44 to rotate by applying elastic force, which in turn drives the scraper 45 to perform preliminary cleaning on the surface of the purifier body 2. At the same time, the drive motor 51 starts and drives the cam 52 to rotate. The rotation of the cam 52 applies pressure to the extrusion plate 54, causing the extrusion plate 54 to slide along the slide rail inside the frame 53. The thrust generated by the extrusion plate 54 during the sliding process acts on multiple rotating plates 44, causing the rotating plates 44 and the scraper 45 to rotate synchronously. Subsequently, when the cam 52 moves away from the extrusion plate 54, the coil spring 46 returns to its initial state and applies a reverse elastic force to the rotating plate 44, quickly driving the rotating plate 44 and the scraper 45 to reset. At this time, the rapid reset of the rotating plate 44 and the scraper 45 and the resulting vibration will shake off the clay adhering to the surface.

[0038] 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.
