[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0032] Combined with Figures 1-8, A stepless adjustable belt conveyor of the present invention includes a belt conveyor base 1. A conveying angle adjusting component 2 is provided on the top of the belt conveyor base 1. The conveying angle adjusting component 2 includes an adjusting frame main body 208, and the adjusting frame main body 208 is installed on the top of the belt conveyor base 1. An infinitely variable adjustment control component 3 is provided on the side of the adjusting frame main body 208. The infinitely variable adjustment control component 3 includes a motor support base 301, and the motor support base 301 is fixedly connected to the adjusting frame main body 208. A fixed conveying component 4 is provided inside the adjusting frame main body 208. The fixed conveying component 4 includes a device fixing block 401, and the device fixing block 401 is fixedly connected to the adjusting frame main body 208; a limiting card slot 402 is opened inside the device fixing block 401, and a clamping disc 403 is clamped and connected inside the limiting card slot 402, and a connecting rod 404 is fixedly connected to the bottom of the clamping disc 403. A limiting spring 405 is provided on the outer wall of the connecting rod 404, and a roller fixing plate 406 is fixedly connected to the bottom of the connecting rod 404. A limiting roller 407 is movably connected to the side of the roller fixing plate 406, and a limiting conveyor belt 408 is closely attached to the bottom of the limiting roller 407. A pair of connecting rods 404 are symmetrically arranged about the vertical central axis of the device fixing block 401, and the device fixing blocks 401 are equidistantly arranged inside the adjusting frame main body 208. The limiting roller 407 adjusts its own height according to the height of the conveyed goods under the action of the limiting spring 405, and the limiting spring 405 plays an elastic supporting role.

[0033] When the material reaches the bottom of the limiting conveyor belt 408, the limiting conveyor belt 408 is closely attached to the material. The conveying speed of the limiting conveyor belt 408 is the same as that of the discharge conveyor belt 310. The limiting roller 407 rotates under the action of the limiting conveyor belt 408, and the limiting roller 407 presses the limiting conveyor belt 408. The limiting conveyor belt 408 fixes the material. When the height of the material is relatively high, at this time, the limiting roller 407 rises, and the limiting roller 407 drives the roller fixing plate 406, the connecting rod 404, and the clamping disc 403 to rise. At this time, the limiting spring 405 is squeezed and contracted. The elastic supporting force generated by the limiting spring 405 can fix the material. The limiting spring 405 can react in real time according to the change of the material height, without frequent manual operation, thus ensuring the continuity and high efficiency of the material conveying process. At the same time, when the material is pressed and fixed, the limiting spring 405 can provide a buffering effect. The elasticity of the limiting spring 405 can ensure that during the pressing process, the pressure is applied gradually, avoiding sudden strong extrusion, thereby protecting the integrity of the material.

[0034] Combined with Figure 3 , Figure 4, a stepless adjustable belt conveyor of the present invention, a side of the adjustment frame main body 208 is movably connected to an adjustment frame rotating shaft 209, and the adjustment frame rotating shaft 209 is fixedly connected to the belt conveyor base 1. Moreover, a lifting rod rotating shaft 207 is fixedly connected to the bottom of the adjustment frame main body 208. The bottom of the lifting rod rotating shaft 207 is movably connected to an electric lifting rod 206, and the bottom of the electric lifting rod 206 is fixedly connected to a moving block 205. Moreover, a threaded rod main body 202 is threadedly connected inside the moving block 205.

Moreover, one end of the threaded rod main body 202 is movably connected to a threaded rod rotating shaft 203. A limiting outer shell 204 is fixedly connected to the side of the threaded rod rotating shaft 203, and the limiting outer shell 204 is located outside the moving block 205. The adjustment frame main body 208 rotates around the adjustment frame rotating shaft 209 under the action of the lifting rod rotating shaft 207 and the electric lifting rod 206, and the lifting rod rotating shaft 207 adjusts its own rotation angle according to the rotation angle of the adjustment frame main body 208. The width of the chute opened inside the limiting outer shell 204 is the same as the width of the moving block 205, and the moving block 205 horizontally slides under the action of the threaded rod main body 202.

[0035] When the device needs to adjust the angle, start the electric lifting rod 206. The electric lifting rod 206 extends, pushing the lifting rod rotating shaft 207 and the adjustment frame main body 208 to rotate around the adjustment frame rotating shaft 209. The lifting rod rotating shaft 207 adjusts its own rotation angle according to the rotation angle of the adjustment frame main body 208. At the same time, start the servo motor 201. The servo motor 201 drives the threaded rod main body 202 to rotate around the threaded rod rotating shaft 203. Under the action of the threaded rod rotating shaft 203, the moving block 205 moves horizontally to adapt to the horizontal position of the adjustment frame main body 208. The conveying angle adjustment assembly 2 adjusts the angle of the conveyor belt according to different usage requirements to achieve efficient connection of multi-stage conveying. The upper conveyor belt conveys the material to a higher position at a certain angle, and the lower conveyor belt can just catch the material at this position by adjusting the angle and continue to convey it at an appropriate speed and direction. Such a connection method can reduce the pause and loss of the material during the conveying process, thereby improving the overall conveying efficiency.

[0037] When the device is in use, start the device motor 302. The device motor 302 drives the motor rotating shaft 303 and the motor gear 304 to rotate. The motor gear 304 drives the transmission gear 305 and the first synchronous drum 306 to rotate. The motor rotating shaft 303 drives the second drum rotating shaft 308 and the second synchronous drum 309 to rotate by driving the first belt 307. The second drum rotating shaft 308 drives the third drum rotating shaft 313 and the third synchronous drum 314 to rotate by the second belt 312. Under the action of the device motor 302, rotation speeds of the first synchronous drum 306, the second synchronous drum 309, and the third synchronous drum 314 are the same, so that conveying speeds of the feeding conveyor belt 315, the discharge conveyor belt 310, and a limit conveyor belt 408 are the same.
