DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0027] like Figure 1 and Figure 2As shown, the utility model provides a technical solution: a belt conveyor with a height adjustment mechanism, comprising a mounting frame 100 and a conveyor 101 installed therein, and a base plate 200, wherein hinged plates 300 are symmetrically arranged at both ends of the top of the base plate 200, the tops of the two hinged plates 300 are hinged to the two ends of the bottom of the mounting frame 100, the bottoms of the two hinged plates 300 are rotatably connected with sliders 302, the two ends of the top of the base plate 200 are respectively provided with transmission components for driving the sliders 302 to move, the top of the base plate 200 is provided with a driving component that increases the torque of the transmission component and can independently control the start of the two transmission components, the slider 302 can be driven to move by setting the transmission component so as to control the inclination angle between the hinged plate 300 and the mounting frame 100, thereby adjusting the height between the mounting frame 100 and the base plate 200, and the driving component can be conveniently arranged to drive two more hinged plates 300, thereby changing the height or angle of the mounting frame 100 and improving adaptability.

[0028] Specifically, Figure 5 As shown, in order to adjust the hinged plate 300, the transmission assembly includes an adjusting screw 306 rotatably connected to the two ends of the top of the base plate 200, and the two adjusting screws 306 are respectively threadedly connected to the two sliders 302, and the two ends of the top of the base plate 200 and located below the adjusting screw 306 are fixedly connected with a slide rail 307, and the two sliders 302 are respectively slidably connected to the two slide rails 307. By setting the slide rail 307, stable movement can be provided for the slider 302.

[0029] Among them, Figure 3 and Figure 5 As shown, in order to improve the stability of the slider 302 when it is stationary and to increase the support strength of the hinge plate 300, multiple screw holes 305 are evenly opened at both ends of the top of the bottom plate 200. Side wing plates 303 are evenly fixedly connected to both sides of the two sliders 302, and fixing bolts 304 threadedly connected to the multiple screw holes 305 are slidably connected inside the side wing plates 303, wherein the fixing bolts 304 can be connected to the screw holes 305 to fix the position of the slider 302, thereby reducing the pressure of the adjusting screw 306.

[0030] Further, such as Figure 3 and Figure 4As shown, in order to facilitate the separate or joint driving of the adjusting screw 306 to rotate, so as to achieve the height adjustment or angle adjustment of the mounting frame 100, the driving assembly includes a dual-axis motor 400 fixedly connected to the top of the base plate 200, the output shafts at both ends of the dual-axis motor 400 are respectively fixedly connected to the active bevel gear 401, the ends of the two adjusting screws 306 close to each other are respectively fixedly connected to the worm gear 402, and the two ends of the top of the base plate 200 and located below the two worm gears 402 are respectively rotatably connected to the worm gears 402 meshing with the worm gears 402. The two worm gears 403 are connected together, and one end of the two worm gears 403 is fixedly connected to a driven bevel gear 404 meshing with the active bevel gear 401. By arranging the cooperation between the worm gear 403 and the worm wheel 402, the torque of the adjustment screw 306 can be increased, thereby improving the stability of the movement of the slider 302. By arranging a dual-axis motor 400, the operation of its two output shafts can be controlled to drive the rotation of the adjustment screw 306 individually or jointly, thereby improving flexibility. The dual-axis motor 400 is a prior art and will not be described in detail here.

[0031] In order to improve the flexibility of the use scenarios of the conveyor 101, a plurality of universal wheels 201 are evenly and fixedly connected to both ends of the bottom of the base plate 200.

[0032] To further increase the strength of the hinged plate 300 in supporting the mounting frame 100, auxiliary movable plates 301 are hinged at both ends of the top of the bottom plate 200 and are rotatably connected to the hinged plate 300. The auxiliary movable plates 301 can assist the hinged plate 300 in providing support and distributing pressure.

[0033] In summary, by providing the cooperation between the adjusting screw 306 and the slider 302, the inclination angle between the hinge plate 300 and the mounting frame 100 can be adjusted, thereby changing the height position between the mounting frame 100 and the base plate 200; by providing the dual-axis motor 400, the rotation of the two adjusting screws 306 can be controlled respectively, thereby flexibly adjusting the angle or height of the mounting frame 100 and improving compatibility; by providing the worm 403 and the worm wheel 402, the torque of the adjusting screw 306 can be increased, and the rotational torque of the adjusting screw 306 can be increased; wherein the cooperation between the fixing bolt 304 and the screw hole 305 can improve the stability of the slider 302 and reduce the pressure on the adjusting screw 306.

[0034] Working principle: When the height of the conveyor 101 needs to be adjusted during use, the fixing bolt 304 can be rotated to rotate in the side wing plate 303, thereby moving up and out of the screw hole 305, thereby releasing the connection and fixation between the slider 302 and the bottom plate 200. At this time, the dual-axis motor 400 is turned on to make its two output shafts rotate together, thereby driving the active bevel gear 401 to rotate and engage with the driven bevel gear 404, thereby driving the worm 403 to rotate. At this time, the worm 403 is engaged with the worm wheel 402, thereby driving the adjusting screw 306 to rotate. At this time, the adjusting screw 306 rotates, thereby driving the slider 302 to slide on the slide rail 307 and move from the bottom of the hinged plate 300. At this time, the bottom of the hinged plate 300 will be away from the top of the hinged plate 300. When the slider 302 moves in the direction close to the top of the hinged plate 300, the angle between the top of the hinged plate 300 and the bottom of the mounting frame 100 will gradually approach the vertical angle, thereby pushing the mounting frame 100 to move upward. When it moves to the desired position, the fixing bolt 304 can be rotated to make it enter the screw hole 305 for limit fixing. At the same time, when it is necessary to adjust the angle of the conveyor 101, one output shaft of the dual-axis motor 400 is controlled to rotate, thereby driving one hinged plate 300 at the bottom of the mounting frame 100 to run, while the other hinged plate 300 is stationary, thereby adjusting the inclination angle of the mounting frame 100.

[0035] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
