Technical Field

[0001] The utility model relates to the technical field of soil tillage, in particular to a soil tillage mechanism with a cleaning function. Background Art

[0002] Soil tillage mechanism, also known as soil tiller or rotary tiller, is a commonly used mechanical equipment in agricultural production. It is mainly used for various farmland operations such as rotary tillage, loosening, and crushing of soil. There are many types, such as handheld lithium-powered micro-tillers, small gasoline micro-tillers, diesel rotary tillers, crawler micro-tillers, etc.

[0003] A Chinese patent application CN201720736454.4 discloses a tiller, comprising a frame, a rotating shaft fixedly mounted on the frame, at least two rotating disks mounted on the rotating shaft, a plurality of tilling teeth fixedly mounted on the outer contour of the rotating disk, a power machine fixedly mounted on the frame, the power machine being connected to the rotating shaft via a belt or chain, and an outer cover fixedly mounted on the frame, the outer cover covering the rotating disk and the tilling teeth. This utility model overcomes the incompatibility of single-plow-arm tillers with dry soil cultivation, replaces manual digging and tillage methods, is flexible and reliable, has high tillage efficiency, good tillage quality, and significantly reduces labor intensity and arable land costs. Furthermore, it can directly form a ridge structure after tilling, avoiding the need for manual work at a later stage, further reducing labor intensity.

[0004] During use, the tillers in the existing and above technologies lack a cleaning device, which causes the soil splashed during the tillage process to adhere to the surface of the protective cover. If the soil is wet, the adhesion phenomenon is more obvious. At this time, when the tiller is used to turn the soil, the tiller with a large amount of soil adhered will greatly consume the physical strength of the workers. Therefore, in order to solve the above problems, a soil tillage mechanism with a cleaning function is proposed. Utility Model Content

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1-3 As shown, a soil tillage mechanism with a cleaning function includes a protective plate 1, a motor 6 and a scraper 7. The motor 6 is mounted on the surface of the protective plate 1 and is a servo motor 6 for driving the scraper 7.

[0029] The surface of the protective plate 1 is fixedly connected to a vertical plate 5, and a guide rail groove 2 is opened on the surface of the vertical plate 5. There are two guide rail grooves 2, and the pair of guide rail grooves 2 are symmetrically distributed around the central axis of the protective plate 1;

[0030] There are two connecting blocks 10, both of which are slidably connected to the guide rail groove 2, and the scraper 7 is fixedly connected to the surface of the connecting block 10;

[0031] A pair of connecting blocks 10 are fixedly connected to a transverse axis 9 on one side close to each other, a fixing block 8 is fixedly connected to the surface of the transverse axis 9, a spring is fixedly connected between the fixing block 8 and the vertical plate 5, a guide rod 11 is fixedly connected to the surface of the vertical plate 5, and the end of the guide rod 11 away from the vertical plate 5 passes through the fixing block 8 for sliding connection, and the spring between the vertical plate 5 and the fixing block 8 is sleeved on the surface of the guide rod 11;

[0032] A through hole 12 is provided on the surface of the vertical plate 5, a pull rope 3 is fixedly connected to the output end of the motor 6, and the end of the pull rope 3 away from the motor 6 passes through the through hole 12 and is fixedly connected to the surface of the horizontal shaft 9. The surface of the scraper 7 has an arc surface, and the cross-section shape is approximately triangular.

[0033] When working, turn on the motor 6 so that the output shaft of the motor 6 will reel in the pull rope 3, and the pull rope 3 will pull the horizontal shaft 9. The horizontal shaft 9 drives the connecting blocks 10 at both ends to move, and the connecting blocks 10 drive the scraper 7 to scrape the inside of the protective plate 1. When the scraper 7 moves to the limit position, the motor 6 reverses, unwinds the pull rope 3, and at the same time the spring resets, driving the scraper 7 to move in the direction away from each other, thereby achieving the effect of scraping back and forth. The scraper 7 cleans the inside of the protective plate 1, which can effectively prevent the soil from adhering to the surface of the protective cover. The tillage opportunity with a large amount of soil adhering to it greatly consumes the physical strength of the workers. The pull rope 3 can be restricted by the through hole 12 to ensure that the pull rope 3 and the rotating shaft of the motor 6 are in a perpendicular state, which is convenient for rewinding. The scraper 7 with an approximately triangular design is more convenient for scraping back and forth, ensuring the cleaning effect of the scraper 7. The design of the guide rod 11 can fix the path of spring contraction and release to avoid arching, which makes the spring lose its reset effect.

[0034] There are two vertical plates 5, one pair of which is respectively arranged on both sides of the motor 6 and is symmetrically designed. A rotating wheel 13 is rotatably connected in the through hole 12, and the pull rope 3 is closely connected to the rotating wheel 13. A groove is opened on the surface of the rotating wheel 13 for positioning the pull rope 3.

[0035] During operation, the two symmetrically designed vertical plates 5 cooperate with the scraper 7 to improve the cleaning efficiency of the protective plate 1. At the same time, the wheel 13 in the through hole 12 can reduce the friction between the pull rope 3 and the vertical plate 5, effectively reduce wear and tear, and increase the service life of the pull rope 3. The groove on the surface of the wheel 13 can limit the pull rope 3 in the middle of the wheel 13 to avoid friction with the side wall of the through hole 12.

[0036] Example 2

[0037] See also Figure 4 As shown, in contrast to Example 1, as another embodiment of the present invention, an arc plate 14 is fixedly connected in the guide rail groove 2, a main magnetic block 15 is fixedly connected to one side of the arc plate 14, a through groove 16 is provided on the surface of the connecting block 10, and the connecting block 10 is slidably connected on the surface of the arc plate 14 through the through groove 16, the scraper 7 is hollow, and a sliding shaft 18 is slidably connected in the scraper 7 through a spring, the sliding shaft 18 passes through the scraper 7 and is slidably connected to the side wall of the through groove 16, the surface of the sliding shaft 18 located in the scraper 7 is fixedly connected to the impact rod 19, the surface of the impact rod 19 is fixedly connected to the impact head, the end portion of the sliding shaft 18 located in the through groove 16 is fixedly connected to the auxiliary magnetic block 17, a plurality of main magnetic blocks 15 are provided, and the main magnetic block 15 and the auxiliary magnetic block 17 are designed for out-of-phase attraction;

[0038] During operation, the pull rope 3 is reeled in by the motor 6, and at the same time, the pull rope 3 pulls the connecting block 10 to slide in the guide rail groove 2. When the connecting block 10 slides, it will drive the scraper 7 to move, and the scraper 7 will drive the internal sliding shaft 18 to move. When the secondary magnetic block 17 on the surface of the sliding shaft 18 moves to the position of the main magnetic block 15, the main magnetic block 15 will instantly adsorb the secondary magnetic block 17 on the surface through the principle of out-of-phase attraction. When the secondary magnetic block 17 moves closer to the main magnetic block 15, it will drive the sliding shaft 18 to move, and the sliding shaft 18 drives the impact rod 19 to move. At the same time, the impact rod 19 drives the impact head to hit the inner wall of the scraper 7, shaking off the dirt on the surface of the scraper 7, thereby ensuring the cleaning effect of the scraper 7. Through the design of multiple main magnetic blocks 15, the impact frequency of the impact head can be increased, further improving the cleaning effect.
