[0002] Belt conveyor is an important material conveying equipment, which can smoothly and continuously convey granular, powdered and block materials. The middle part of the belt conveyor usually relies on multiple groups of roller groups for support and auxiliary material conveying. In order to make the conveyor belt surface of the belt conveyor adjustable as needed, the side rollers of the roller group are usually designed to be adjustable. When adjusting the side rollers of the existing belt conveyor, it is necessary to adjust them one by one gradually, which is cumbersome and affects the use of the conveyor. Moreover, when the side rollers are used for a long time, the side rollers are prone to rust, which not only generates a lot of noise, but also affects the stable conveying of the conveyor.

The guide rod 268 extends into the guide groove 266. When the side roller 210 needs to be replaced, the push rod 1 240 is pulled, and the limit block 253 moves in the direction close to the support plate 3 251, thereby driving the push rod 265 and the guide plate 264 to move in the direction close to the guide column 261, thereby driving the push plate 262 to move along the guide column 261 toward the plate surface close to the baffle 137, and then pushing the rubber column 263 to move, and the end of the rubber column 263 contacts the circumference of the side roller 210, thereby pushing the side roller 210 out, so as to facilitate the replacement of the side roller 210.

[0040] like Figure 4 , Fig. 9As shown, a connecting assembly 170 is provided on the support frame 110, and the connecting assembly 170 includes a second support plate 171, a guide column 172, a top contact 173, a rotating shaft 174, and a limiting ring 175. The second support plate 171 is fixed to the wall of the support frame 110, and the connecting plate 133 is connected to the support frame 110 through the rotating shaft 174. The limiting ring 175 is coaxially fixedly sleeved on the end of the rotating shaft 174, and arc grooves are evenly spaced on the circumference of the limiting ring 175.

When the roller group 20 on the opposite side is assembled, the top contact 173 conflicts with the limiting ring 175, thereby preventing the mounting frame 130 from naturally hanging down, so that multiple groups of mounting frames 130 maintain the same deflection angle, which is easy to install.

[0041] More specifically, the limiting block 253 is arranged at an angle away from the side wall of the baffle 137 to facilitate the abutment installation of the side roller 210 .

[0042] More specifically, a ball 136 is provided at the end of the limiting column 135, and the end of the limiting column 135 contacts the belt surface of the conveyor belt through the ball 136 to avoid damage to the conveyor belt.

[0043] Working principle:

[0044] During the use of the present invention, when the side roller 210 is installed, the push rod 1 240 is pulled and the limit block 253 is moved toward the direction close to the support plate 3 251, and then the side roller 210 is placed between the bearing block 131 and the bearing block 2 132, and then the pull on the push rod 1 240 is canceled, the limit block 253 is reset, and the central axis of the side roller 210 matches the arc-shaped end surface of the limit seat 256. The limit block 253 limits the central axis of the side roller 210, and the elastic force of the spring 2 pushes the limit seat 256 to move toward the direction close to the limit column 135, so that the side roller 210 is in close contact with the conveyor belt surface of the conveyor belt, which is beneficial to the transmission of the conveyor belt. When the side roller 210 needs to be replaced, the push rod 1 240 is pulled and the limit block 253 is moved. It moves toward the direction close to the support plate three 251, thereby driving the push rod two 265 and the guide plate 264 to move toward the direction close to the guide column two 261, thereby driving the push plate 262 to move along the guide column two 261 toward the plate surface close to the baffle 137, and then pushes the rubber column 263 to move. The end of the rubber column 263 contacts the circumference of the side roller 210, thereby pushing the side roller 210 out to facilitate the replacement of the side roller 210. When the side roller group 20 is assembled, the top contact head 173 contacts the limit ring 175, thereby preventing the mounting frame 130 from naturally hanging down, so that multiple groups of mounting frames 130 maintain the same deflection angle, which is convenient for installation. The hydraulic cylinder 140 can adjust the angle of multiple groups of mounting frames 130, thereby adjusting the inclination angle of the side roller group 20.

[0045] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention.
