[0011] Figure 2 This is a top view of the drive linkage in this invention. Detailed Implementation
[0012] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0013] See Figure 1-2This specific embodiment is implemented using the following technical solution, which includes a conveyor box 1. Inside the conveyor box 1, there is a driven friction pulley 2 and a driven friction pulley 3. The driven friction pulley 2 is rotatably connected to the inner wall of the conveyor box 1 through a first rotating shaft 4. The driven friction pulley 3 is rotatably connected to the inner wall of the conveyor box 1 through a second rotating shaft 5. The driven friction pulley 2 and the driven friction pulley 3 are connected by a conveyor belt 6 for belt drive. A drive device and a clutch device for driving the driven friction pulley 3 to rotate forward and backward are installed on one side of the driven friction pulley 3.
[0014] The drive device includes a first drive motor 7, which is integrally mounted on a linkage plate 8. The bottom of the linkage plate 8 can slide against the bottom surface of the conveyor box 1 with a gap. The power output shaft of the first drive motor 7 extends out of the linkage plate 8 and axially connects with the drive shaft 9. A first drive gear 10 and a second drive gear 11 are fixedly mounted on the drive shaft 9. A first driven gear 12 and a second driven gear 13 are respectively mounted on a second rotating shaft 5 at both ends of the drive friction pulley 3. A transmission gear 14 that can mesh with the second driven gear 13 is provided on one side. The transmission gear 14 is rotatably connected to a third rotating shaft 15 mounted on the inner wall of the conveyor box 1. The first drive gear 10 can mesh with the first driven gear 12, and the second drive gear 11 can mesh with the transmission gear 14.
[0015] The clutch device includes a threaded sleeve 25 fixedly mounted on the linkage plate 8. A screw 16 is provided inside the threaded sleeve 25, which can be screwed into it. One end of the screw 16 passes through a square positioning slider 17 that is rotatably connected to it and connects to the power output shaft end of the second motor 18. A positioning groove 19 is provided on the side wall of the conveying box 1, which can be slidably engaged with the square positioning slider 17. The square positioning slider 17 can slide horizontally along the length of the positioning groove 19. The second motor 18 is fixedly mounted on the outer side of the square positioning slider 17. A drive connecting rod 20 is installed on the outer side of the threaded sleeve 25. One end of the drive connecting rod 20 is provided with a shift fork groove 24 that can be slidably engaged with the clutch plate 21. A clutch shaft 22 is installed in the shift fork groove 24. A clutch groove 23 is provided on the clutch plate 21, which can be slidably engaged with the clutch shaft 22.
[0016] The clutch groove 23 is C-shaped in general, and the opening of the C-shaped clutch groove 23 faces the screw 16.
[0017] The following, in conjunction with the accompanying drawings, further elaborates on the usage method and principle of the technical solution in this specific embodiment:
[0018] When materials need to be transported, assuming that the first driving gear 10 is engaged with the first driven gear 12, it is only necessary to start the first drive motor 7 to drive the entire second driven gear 13 to rotate using the first driving gear 10 and the first driven gear 12.
[0019] When it is necessary to change the conveying direction, the second motor 18 is started to drive the screw 16 to rotate. During the rotation of the screw 16, the drive shaft 9, the drive connecting rod 20, and the linkage plate 8 move horizontally in the direction of the third rotating shaft 15. During the movement, the clutch shaft 22 in the drive connecting rod 20 disengages the first driving gear 10 from the first driven gear 12 along the direction of the clutch groove 23, thereby achieving the purpose of disengagement. Then, as the clutch shaft 22 moves further, the second driving gear 11 gradually meshes with the transmission gear 14, thereby achieving the purpose of engagement, and finally achieving the purpose of changing the conveying direction of the conveyor belt.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
