[0017] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, the seesaw pressure-type linkage roller group includes a roller group base, on which a rectangular roller swing frame 1 is rotatably mounted, and the roller swing frame 1 can rotate on the roller group base so that it is in a state of one end high and one end low along the material conveying direction, so as to adjust the contact amount between this embodiment and the conveying belt 2. The roller group base includes two roller group brackets 3 arranged opposite to each other, and the top of each roller group bracket 3 is detachably mounted with a swing frame pin 4, the roller swing frame 1 is arranged between the two roller group brackets 3, and each swing frame pin 4 passes through the roller swing frame 1 and is rotatably arranged, and the swing frame pin 4 is assembled in the middle of the roller swing frame 1, so as to ensure that the conveying belt 2 is under normal full-load conveying state, each roller group bracket 3 can be evenly stressed to maintain the balance stability of the roller swing frame 1. The roller group bracket 3 is set as an A-shaped bracket, which has a simple structure and a firm and stable support.

[0019] At least two groups of roller support frames 5 are installed and supported on the roller swing frame 1, and rollers 6 are correspondingly arranged and installed on each of the roller support frames 5. Generally, three rollers 6 are arranged on the same roller support frame 5, one of which is horizontally arranged and the other two are inclined at both sides. The three rollers 6 are roughly arranged in a V shape, and the conveyor belt 2 is supported on each of the rollers 6 to realize its conveying movement and support.

[0020] like Figure 4 As shown, a counterweight device is movably provided at one end of the roller swing frame 1. The counterweight device is arranged in a detachable connection mode. When the conveyor belt 2 is in an unloaded or low conveying state, the counterweight device is installed at the bottom of the roller swing frame 1, so that the roller swing frame 1 is in a state where one end is high and the other end is low along the material conveying direction. If two groups of the roller support frames 5 are installed on the roller swing frame 1, at least most of the rollers 6 will not contact the conveyor belt 2 at this time, thereby reducing the usage of the rollers 6 by half, that is, reducing the resistance generated by the rollers 6 on the conveyor belt 2 during operation, and reducing the wear between the two, thereby achieving the effect of reducing resistance and loss.

[0021] like Figure 5 As shown, the counterweight device includes a counterweight hanger 7 detachably mounted on the bottom of the roller swing frame 1, such as by the cooperation of a hook and a hanging ring to hook the counterweight hanger 7 on the roller swing frame 1. At least one counterweight block 8 is detachably provided on the counterweight hanger 7, and a counterweight upright rod 9 can be provided on the counterweight hanger 7, and each counterweight block 8 can be detachably mounted on the counterweight upright rod 9.

[0022] According to the different conveying amounts of the conveying belt 2, the forces acting on the roller 6 are also different. The amount of the counterweight 8 can be increased or decreased according to the specific situation during use, so that the inclination adjustment of the roller swing frame 1 can be smoothly achieved, and the operation of increasing or decreasing the counterweight 8 is simple and convenient.

[0023] Generally, the counterweight device is arranged in the middle of the feeding side or the discharging side of the roller swing frame 1 to make the roller swing frame 1 evenly stressed and prevent it from being deformed after long-term use, which helps to ensure its service life and the stability of the conveyor belt 2.
