Detailed Description

Specific embodiments of the utility model will be described in further detail below with reference to the drawings to facilitate a more readily apparent understanding of those skilled in the art.

As shown in fig. 1, the embodiment comprises a bearing table 1, a weighing sensor 15 connected with the bottom surface of the bearing table, and slopes 2 positioned at two ends of the bearing table.

As shown in fig. 1 and fig. 3, four buffer assemblies are arranged between the bearing table and the slope, two buffer assemblies are arranged at each end of the bearing table, the two buffer assemblies are connected in two grooves at the end of the bearing table in a one-to-one correspondence manner, each buffer assembly comprises a guide rod 14, a sliding plate 4, a spring 3 and a roller 5, one end of each guide rod is connected with a vertical wall of the groove, the other end of each guide rod is connected with a limiting pin, the sliding plate is connected with the guide rod in a sliding manner, one end of each spring is connected with the vertical wall of the groove, the other end of each spring is connected with one side of the sliding plate, the other side of each sliding plate is connected with a connecting lug, the other end of each connecting lug is connected with a pin shaft, and the roller rotates the connecting pin shaft.

As a further improvement of this embodiment, as shown in fig. 2 and fig. 4, the front end of the bearing table is further provided with two limiting components, the two limiting components are respectively arranged on the left side and the right side of the bearing table, the limiting components comprise a supporting frame 6, a hydraulic cylinder 13, a limiting block 10 and a limiting block guide rod 8, the supporting frame is connected to the side surface of the bearing table, the hydraulic cylinder is connected to the upper portion of the supporting frame, the limiting block is connected with the end of the pushing rod of the hydraulic cylinder, the bottom surface of the limiting block is connected with a sliding block 9, the sliding block is in sliding connection with the limiting block guide rod, the limiting block guide rod is arranged in a bar-shaped groove 7 of the bearing table, and two ends of the limiting block guide rod are respectively connected with two end walls of the bar-shaped groove in a one-to-one correspondence manner.
