[0002] Shaft pins for agricultural machinery play a crucial role in agricultural machinery and equipment. They are mainly used to connect and fix various mechanical components to achieve the functions of connection, transmission, and support. They usually have a cylindrical shape and can be fixed in bearings, journal bearings, or other parts through a hole or groove.

[0003] For the existing shaft pins for agricultural machinery, the installation and disassembly operation steps are relatively cumbersome, and other independent parts are also required for cooperation, which is rather inconvenient. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a detachable shaft pin for agricultural machinery, which can solve the problems that the installation and disassembly operation steps of the shaft pin in the prior art are relatively cumbersome, other independent parts are required for cooperation, and it is rather inconvenient.

[0005] To solve the above technical problem, the technical solution of the utility model is as follows: it includes a pin body and a locking member; the pin body is a cylinder; the locking member is rotationally matched with the pin body to achieve locking;

[0006] The locking member includes a U-shaped frame, a triangular rotating frame, and a diamond-shaped fastener. The triangular rotating frame and the diamond-shaped fastener are integrally connected to both ends of the U-shaped frame respectively. One end of the pin body is provided with a perforation along the radial direction of the pin body. The bottom edge of the triangular rotating frame passes through the perforation and is rotationally connected with the pin body;

[0007] The end of the pin body far from the perforation is sleeved in the diamond-shaped fastener and is detachably connected with the diamond-shaped fastener;

[0008] One end of the diamond-shaped fastener far from the U-shaped frame is integrally connected with a guiding frame. The guiding frame is inclined towards the outside of the diamond-shaped fastener far from the triangular rotating frame. One end of the pin body close to the diamond-shaped fastener slides into the diamond-shaped fastener along the guiding frame.

[0009] Further, a frustum is integrally provided at the end of the pin body far from the perforation.

[0010] Further, the end of the diamond-shaped fastener far from the U-shaped frame is an opening, and the opening is integrally connected with both ends of the guiding frame.

[0011] Further, the guiding frame includes a first frame body and a second frame body. The distance between the first frame body and the second frame body gradually increases from the end close to the diamond-shaped fastener to the end far from the diamond-shaped fastener, and the ends of the first frame body and the second frame body far from the diamond-shaped fastener are connected by an arc section.

[0012] Furthermore, the length of the bottom side of the triangular rotating frame is greater than the diameter of the pin body.

[0013] After adopting the above structure, the advantage of the utility model is that when different mechanical parts of the agricultural machinery are connected by the axle pin, the pin body and the diamond fastener are in the open state, and the pin body is passed through the axle setting. When locking is required, the U-shaped frame is rotated to drive the triangular rotating frame to rotate relative to the pin body. After the round table at one end of the pin body contacts the guide frame, the pin body and the U-shaped frame are buckled, so that the round table slides along the guide frame until the round table enters the diamond fastener, and one end of the pin body is buckled in the diamond fastener to complete the locking. The locking operation is convenient. When opening is required, the guide frame is grasped, the end of the round table is pressed, and the guide frame is pulled outward to make the round table detach from the diamond fastener to complete the opening operation. The installation and disassembly operations are very convenient, and no other independent parts are required to cooperate, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments can enable technicians in this field to understand the utility model more comprehensively, but the utility model is not limited to the scope of the embodiments.

[0019] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a pin body 1 and a locking member 2; the pin body 1 is a cylinder, one end of the pin body 1 is provided with a through hole 11 along the radial direction of the pin body 1, and the end of the pin body 1 away from the through hole 11 is integrally provided with a frustum 12.

[0020] The locking member 2 is rotatably engaged with the pin body 1 to achieve locking. The locking member 2 includes a U-shaped frame 21, a triangular rotating frame 22 and a diamond-shaped fastener 23. The triangular rotating frame 22 and the diamond-shaped fastener 23 are integrally connected to both ends of the U-shaped frame 21 respectively. The bottom edge of the triangular rotating frame 22 passes through the through hole 11 and is rotatably connected to the pin body 1. The length of the bottom edge of the triangular rotating frame 22 is greater than the diameter of the pin body 1. The bottom edge of the triangular rotating frame 22 can slide within the through hole 11 of the pin body 1. The triangular rotating frame 22 can be sleeved and connected to a chain or the like to realize connection with other parts.

[0021] One end of the pin body 1 away from the through hole 11 is sleeved within the diamond-shaped fastener 23 and is detachably connected to the diamond-shaped fastener 23. When the pin body 1 is sleeved within the diamond-shaped fastener 23, locking is achieved. When the pin body 1 is disassembled from the diamond-shaped fastener 23, that is, the pin body 1 is not sleeved within the diamond-shaped fastener 23, unlocking can be realized.

[0022] One end of the diamond-shaped fastener 23 away from the U-shaped frame 21 is integrally connected with a guiding frame 24. The guiding frame 24 is inclined towards the outside of the diamond-shaped fastener 23 away from the triangular rotating frame 22. The end of the diamond-shaped fastener 23 away from the U-shaped frame 21 is an opening, and both ends of the opening are integrally connected with the guiding frame 24. The guiding frame 24 includes a first frame body 241 and a second frame body 242. The distance between the first frame body 241 and the second frame body 242 gradually increases from the end close to the diamond-shaped fastener 23 to the end away from the diamond-shaped fastener 23, and the ends of the first frame body 241 and the second frame body 242 away from the diamond-shaped fastener 23 are connected by an arc section 243. The setting of the arc section 243 makes it not be scratched during operation and is safer to use. When locking, one end of the pin body 1 close to the diamond-shaped fastener 23 slides along the guiding frame 24 into the diamond-shaped fastener 23.

[0023] Working principle: Different mechanical components of agricultural machinery can be connected through the agricultural machinery shaft pin. When connecting, the pin body 1 is arranged through the shaft. At this time, the pin body 1 and the diamond-shaped fastener 23 are in an open state. When locking is required, rotate the U-shaped frame 21 to drive the triangular rotating frame 22 to rotate relative to the pin body 1. After the round table 12 at one end of the pin body 1 contacts the guiding frame 24, press the pin body 1 and the U-shaped frame 21, so that the round table 12 slides along the guiding frame 24 until the round table 12 enters the diamond-shaped fastener 23. One end of the pin body 1 is buckled within the diamond-shaped fastener 23 to complete the locking. The locking operation is convenient; when opening is required, hold the guiding frame 24, press the end of the round table 12, and pull the guiding frame 24 outwards so that the round table 12 disengages from the diamond-shaped fastener 23 to complete the opening operation. The installation and disassembly operations are both very convenient, and no other independent parts are required for cooperation, so the practicability is strong.
