[0022] like Figure 1-3 As shown, the adjustment component 2 includes a fixed box 201 fixedly installed inside the pulley body 1, a double-headed threaded rod 202 is fixedly installed between the front and rear side walls of the inner wall of the fixed box 201, a driving component 203 for driving the double-headed threaded rod 202 to rotate is arranged on the top of the fixed box 201, and movable plates 204 are threadedly connected on both sides of the double-headed threaded rod 202 with opposite thread directions. The top and bottom of the two movable plates 204 are provided with limit assemblies 205 to prevent them from rotating, and push rods 206 with one end penetrating and extending to the left and right sides of the fixed box 201 are fixedly installed on the opposite sides of the two movable plates 204, and connecting rods 207 with one end penetrating and extending to the outside of the pulley body 1 are fixedly installed on the opposite sides of the two push rods 206. The outer side of the pulley body 1 is slidably connected to a limit ring 208, and the two ends of the two connecting rods 207 are respectively fixedly connected to the inner sides of the two limit rings 208.

[0023] It should be noted that the driving assembly 203 includes a rotating rod 2031 rotatably connected to the top of the fixed box 201 and extending into the interior thereof, a supporting assembly 2032 is provided inside the fixed box 201 to support the rotating rod 2031, a bevel gear assembly 2033 is provided at the bottom of the rotating rod 2031, and a rotating assembly 2034 is provided at the top of the rotating rod 2031.

[0024] Among them, the rotating component 2034 includes a rotating block fixedly installed on the top of the rotating rod 2031, a plum blossom groove is opened on the top of the rotating block, and a through hole corresponding to the position of the rotating block is opened on the outer side of the pulley body 1. The through hole allows a person passing by to use a plum blossom screwdriver to rotate the plum blossom groove. When the plum blossom groove rotates, the plum blossom groove will drive the rotating block to rotate, and the rotating block will drive the rotating rod 2031 to rotate.

[0025] In addition, the support assembly 2032 includes a horizontal plate fixedly installed between the front and rear side walls of the inner cavity of the fixed box 201, and the rotating rod 2031 is rotatably connected to the inside of the horizontal plate through a bearing.

[0026] It should be noted that the bevel gear assembly 2033 includes a driving bevel gear fixedly installed at the bottom of the rotating rod 2031, and a driven bevel gear meshing with the driving bevel gear is fixedly installed on the outer side of the double-headed threaded rod 202. When the rotating rod 2031 rotates, the rotating rod 2031 will drive the driving bevel gear to rotate, and the driving bevel gear will drive the pre-engaged driven bevel gear to rotate, and the driven bevel gear will drive the double-headed threaded rod 202 to rotate.

[0027] In addition, the limit assembly 205 includes limit blocks fixedly installed on the top and bottom of the movable plate 204, and the inner top wall and the inner top wall of the fixed box 201 are provided with limit grooves slidably connected to the limit blocks. The movable plate 204 can be limited by the limit blocks and the limit grooves to prevent the movable plate 204 from rotating. When the double-headed threaded rod 202 rotates, under the action of the thread thrust, the two ends of the double-headed threaded rod 202 with opposite thread directions will respectively drive the two movable plates 204 to move to the opposite side or the opposite side, and the two movable plates 204 will respectively drive the two push rods 206 to move to the opposite side or the opposite side.

[0028] Among them, sliding holes that penetrate into the interior of the fixed box 201 are opened on the left and right sides, and the two push rods 206 are respectively slidably connected to the inside of the two sliding blocks. The two sliding holes can respectively ensure the stability of the movement of the two push rods 206. When the two push rods 206 move to the opposite side or the opposite side, the two push rods 206 will respectively drive the two connecting rods 207 to move to the opposite side or the opposite side, and the two connecting rods 207 will respectively drive the two limit rings 208 to move to the opposite side or the opposite side.

[0029] Specifically, by rotating the hexagram slot, the two limit rings 208 can be moved to the opposite side or the opposite side, thereby adjusting the distance between the two limit rings 208 so that the distance between the two limit rings 208 is equal to the width of the belt. Finally, the belt is installed on the outside of the pulley body 1, and the belt is located between the opposite sides of the two limit rings 208. This can avoid the belt from being offset during operation, thereby ensuring the stability of the pulley body 1 during use.

[0030] The working principle of the above embodiment is:

[0031] When using the wear-resistant agricultural machinery pulley accessory, according to the width of the belt to be installed, a plum blossom screwdriver is used to rotate the plum blossom slot through the through hole, the plum blossom slot will drive the rotating block to rotate, the rotating block will drive the rotating rod 2031 to rotate, the rotating rod 2031 will drive the active bevel gear to rotate, the active bevel gear will drive the pre-engaged driven bevel gear to rotate, the driven bevel gear will drive the double-headed threaded rod 202 to rotate, under the action of the thread thrust, the two ends of the double-headed threaded rod 202 in opposite directions of the thread will respectively drive the two movable plates 204 to move to the opposite side or the opposite side, and the two movable plates 204 will respectively drive The two push rods 206 are moved to the opposite side or the opposite side, and the two push rods 206 will respectively drive the two connecting rods 207 to move to the opposite side or the opposite side, and the two connecting rods 207 will respectively drive the two limiting rings 208 to move to the opposite side or the opposite side, thereby adjusting the distance between the two limiting rings 208 so that the distance between the two limiting rings 208 is equal to the width of the belt. Finally, the belt is installed on the outside of the pulley body 1 and the belt is located between the opposite sides of the two limiting rings 208. This can avoid the belt from being offset during operation, thereby ensuring the stability of the pulley body 1 during use.
