DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] See also Figure 1-4 The utility model provides a knife shaft anti-entanglement device for a rotary tiller, comprising a frame 1 and a main shaft 2, the main shaft 2 is rotatably connected to the inner side wall of the frame 1, a plurality of equally distributed mounting ring frames 3 are fixed to the outer surface of the main shaft 2, a plurality of circumferentially distributed rotary tilling knives 4 are fixed to the side wall of one side of the mounting ring frame 3, and a debris removal component 5 adapted to the rotary tilling knives 4 is arranged on one side of the frame 1.

[0026] Further Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it is worth specifically explaining that the impurity removal component 5 includes a channel 51, which is opened on the top side wall of the frame 1, and a mounting plate 52 is slidably connected inside the channel 51. A threaded hole 53 is opened on one side wall of the mounting plate 52, and a screw 54 is threadedly connected at the threaded hole 53. A rotating wheel 55 is fixed to one end of the screw 54, and a scraper 56 is rotatably connected to the other end of the screw 54; two bearing seats 57, the two bearing seats 57 are symmetrically distributed and fixed to the top side wall of the frame 1, and the side walls of the two adjacent bearing seats 57 are rotatably connected with a screw 58, a support plate 59 is fixed to one side wall of the frame 1, and a servo motor 510 is fixed to the top side wall of the support plate 59, and one end of the output shaft of the servo motor 510 is coaxially fixed with one end of the screw 58 ; Two mounting blocks 511, the two mounting blocks 511 are symmetrically distributed and fixed on the top side wall of the mounting plate 52, one of the mounting blocks 511 is threadedly connected to the screw rod 58, and the top side wall of the frame 1 is fixed with two symmetrically distributed mounting seats 512, and the adjacent side walls of the two symmetrically distributed mounting seats 512 are jointly fixed with a guide rod 513, and the other mounting block 511 is slidably sleeved on the outer surface of the guide rod 513. Through the setting of the debris removal component 5, it is convenient for the staff to clean up the debris entangled on the main shaft 2 and the rotary tiller 4 in time, further saving the staff's labor and physical strength in cleaning the rotary tiller 4, saving more time and effort, and ensuring that the use effect of the rotary tiller 4 after cleaning is in a good state.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the length of the guide rod 513 is consistent with the length of the screw rod 58, and the guide rod 513 and the screw rod 58 are respectively located on both sides of the screw rod 54. By setting the length of the guide rod 513 and the screw rod 58, it is possible to ensure that the mounting block 511 always moves under the guidance of the guide rod 513 to avoid displacement.

[0028] This solution has the following working process: when it is necessary to clean up the debris entangled on the main shaft 2 and the rotary tiller 4, the servo motor 510 is driven to make the screw rod 58 rotate synchronously, and the threaded transmission effect between the mounting block 511 and the screw rod 58 is used to cause the mounting block 511 to move under force, driving the mounting plate 52 to move synchronously, and cooperating with the setting of the guide rod 513, it plays a guiding role in the movement of the mounting plate 52, so that the mounting plate 52 moves at a uniform speed along the groove after being forced, and ensures that the scraper 56 is moved to the appropriate position. By rotating the rotating wheel 55, the screw rod 54 is rotated synchronously, and the threaded transmission effect between the screw rod 54 and the threaded hole 53 is used to cause the scraper 56 to move downward under the guidance of the guide rod 6. After the adjustment of the scraper 56 is completed, the scraper cleans the debris entangled on the outer surface of the main shaft 2 and the debris on the rotary tiller 4 through the operation of the main shaft 2.

[0029] According to the above working process, it can be known that: through the setting of the debris removal component 5, it is convenient for the staff to clean up the debris entangled on the main shaft 2 and the rotary tiller 4 in time, which further saves the staff's physical labor for cleaning the rotary tiller 4, saves time and effort, and ensures that the use effect of the rotary tiller 4 after cleaning is in a good state. By adopting the setting of the screw rod 58, the position and height of the scraper 56 can be adjusted according to the specific situation, which is convenient for cleaning the debris entangled at different positions, and the operation is convenient and simple. Compared with the traditional manual cleaning method of the staff, the device has a better and more convenient cleaning effect on the rotary tiller 4 and the main shaft 2.

[0030] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that two symmetrically distributed guide rods 6 are slidably penetrated through the side wall of one side of the mounting plate 52, and one end of the two guide rods 6 is fixed to the top side wall of the scraper 56. The scraper 56 and the main shaft 2 are arranged in an inclined distribution. Through the setting of the guide rods 6, a guiding effect is played when the scraper 56 is moved under force, ensuring that the scraper 56 can be in a stable rising and falling moving state, and the scraper 56 is better protected.

[0031] Further as Figure 3 As shown, it is worth explaining in detail that a limiting ring 7 is fixed to the end of the guide rod 6 away from the scraper 56, and the diameter of the limiting ring 7 is greater than the diameter of the guide rod 6. The setting of the limiting ring 7 plays a role in limiting the guide rod 6, thereby preventing the guide rod 6 from falling off from the mounting plate 52 due to excessive movement.

[0032] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the vertical cross-section of the support plate 59 is set in an L shape, and the angle between the support plate 59 and the frame 1 is set at a right angle. Through the setting of the support plate 59, the connection stability between the support plate 59 and the frame 1 is greatly improved, avoiding the support plate 59 from shaking or even being damaged.

[0033] In summary: by setting the length of the guide rod 513 and the screw rod 58, it is possible to ensure that the mounting block 511 always moves under the guidance of the guide rod 513 to avoid displacement, and by setting the guide rod 6, it plays a guiding role when the scraper 56 is moved under force, ensuring that the scraper 56 can be in a stable rising and falling state, which provides good protection for the scraper 56, and by setting the limiting ring 7, it plays a limiting role on the guide rod 6 to prevent the guide rod 6 and the mounting plate 52 from falling off due to excessive movement, and by setting the support plate 59, the connection stability between the support plate 59 and the frame 1 is greatly improved to avoid the support plate 59 from shaking or even breaking.

[0034] The servo motor 510 can be purchased on the market. The servo motor 510 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it is not repeated in the specification.
