[0026] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0027] like Figure 1 - Appendix Figure 8This utility model provides a rice knife adjustment device for a rice milling machine, including a support plate 1, a housing 2, and an arc-shaped support plate 18. A connecting shaft 6 is provided in the middle of the support plate 1. An adjustment mechanism 3 is assembled inside the housing 2, and a support mechanism 4 is assembled outside the connecting shaft 6. The adjustment mechanism 3 includes a rice knife 32, and an arc-shaped plate 33 is provided at the bottom of the rice knife 32.

A rotating groove 35 is provided on the outer side of the support plate 1. An arc-shaped plate 33 is rotatably connected to the inside of the rotating groove 35 on the side near the rotating groove 35. A connecting post 36 is provided on the side of the katana 32 away from the support plate 1. A circular plate 37 is provided on the outer side of the connecting post 36. A first threaded rod 38 is provided on the side end of the circular plate 37. Multiple threaded grooves 39 are provided in a ring shape on the side end of the housing 2. The outer side of the first threaded rod 38 is threadedly connected to the inside of the threaded groove 39. Multiple second connecting rods 5 are provided on the side of the support plate 1 near the housing 2. The support plate 1 and the housing 2 are connected by multiple second connecting rods 5. The housing 2 is equipped with a connecting cylinder 14. The housing 2 and the connecting cylinder 14 are equipped with injection ports 15. The support plate 1 is equipped with a motor 7 inside. The output shaft of the motor 7 is equipped with a transmission column 8. The transmission column 8 is equipped with a synchronous belt 9 on the outside. The housing 2 is equipped with a connecting column 10 on the side near the support plate 1. The connecting column 10 is connected to the transmission column 8 through the synchronous belt 9. The connecting column 10 is equipped with a connecting circular plate 11 through the side end of the housing 2 on the side away from the support plate 1. The connecting circular plate 11 is symmetrically equipped with two third connecting rods 12 on the side away from the motor 7. The housing 2 is equipped with a roller 13. The roller 13 is connected to the inside of the housing 2 through the two third connecting rods 12. The roller 13 is rotatably connected to the side end of the connecting cylinder 14 on the side near the connecting cylinder 14. Multiple fourth connecting rods 17 are arranged in a ring on the inner side of the connecting cylinder 14. The connecting shaft 6 is equipped with a spiral shaft 16 on the side end.

[0028] The overall effect of Embodiment 1 is as follows: the relevant components can improve the accuracy of adjusting the position of the rice knife 32 of the traditional rice milling machine through mechanical transmission. The function of setting the limiting groove 34 is to limit the rotation of the arc plate 33 and maintain the stability of the arc plate 33 during rotation. The function of setting the fourth connecting rod 17 is that the arc support plate 18 is connected to the inner side of the connecting cylinder 14 through multiple fourth connecting rods 17. This mechanical transmission method can improve the stability of rice output accuracy. The bottom of the shell 2 is opened with a slot to facilitate the falling of rice husks.

[0029] Example 2, as Figures 1-8As shown, the support mechanism 4 includes a through column 41. A second support circular plate 43 is provided on the side of the through column 41 away from the roller 13, and a first support circular plate 42 is provided on the side of the through column 41 close to the roller 13. The outer side of the through column 41 passes through the middle of the support plate 1, the interior of the connecting column 10, the side end of the housing 2, the side end of the connecting circular plate 11, and the side end of the connecting cylinder 14. The side end of the first support circular plate 42 is fixedly connected to the inner side of the connecting cylinder 14. A plurality of second threaded rods 44 are provided on the outer side of the second support circular plate 43.

[0030] The effect achieved by the entire embodiment 2 is as follows: by setting the support mechanism 4, the second threaded rod 44 is screwed into the interior of the support plate 1, the first support circular plate 42 is used to support the connecting cylinder 14, and during the operation of the roller 13, it plays the role of preventing the connecting cylinder 14 from rotating.

[0031] Before starting the inspection, ensure that all parts of the structure are in a stable state to prevent any errors from occurring after the work is completed.

[0032] like Figure 1 As shown, the housing 2 is mounted on the ground via a bracket. An external tool motor is mounted on the side of the support plate away from the housing 2 via the bracket plate. The output shaft of the external tool motor is connected to the connecting shaft 6. When the motor 7 is started, its output shaft drives the transmission column 8 to rotate. The transmission column 8 drives the connecting column 10 to rotate via the synchronous belt 9. When the connecting column 10 rotates, it drives the third connecting rod 12 to rotate via the connecting circular plate 11. The rotation of the third connecting rod 12 drives the roller 13 to rotate. Simultaneously, the external motor is started, and its output shaft drives the screw shaft 16 to rotate via a coupling, injecting grains into the injection port 15. The grains... Under the action of centrifugal force, the grains are thrown against the drum wall. Under the action of gravity, the grains tend to slide downwards, thus moving the rice grains from one side to the other. During this process, the grains will get stuck in the grooves of the drum 13. When the drum 13 rotates, the rice knife removes the husks from the grains stuck on the drum 13. The husks fall into the inside of the arc-shaped support plate 18, and the husks fall into the inside of the shell 2 through the grooves of the drum 13. The husks then fall to the ground through the slots of the shell 2. The operator can collect them with the collection frame. The connecting shaft 6 pushes the husks through the screw shaft 16 to transport the husks to the outlet of the shell 2.

[0033] When adjusting the position of the rice knife 32, the operator rotates the first threaded rod 38, which is screwed out from the internal thread of the threaded groove 39. The connecting column 36 is rotated, which drives the arc plate 33 to rotate outside the rotating groove 35, thereby changing the distance between the rice knife 32 and the inner wall of the roller 13. After adjusting the rice knife 32 to a suitable position, the operator reverses the first threaded rod 38 again, and the first threaded rod 38 is screwed into the inside of the threaded groove 39.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
