The pump 400 is located at the top of the lower alignment plate 110. One end of the pump 400 is connected to the other end of the rotating arm 310. The positioning shaft 330 can fix the rotating arm 310 and the rotating arm 320 when the equipment is working. While one end of the pump 400 is fixed to the connecting shaft, the other end is connected to the lower alignment plate 110 to ensure that the pump 400 has a force point and facilitates the lifting of the equipment. The upper connecting assembly 200 includes an upper alignment block 220 set on the outer wall of the positioning shaft 330. The outer wall of the rotating arm 310 is provided with an upper slider 240, and the outer wall of the upper slider 240 is provided with an upper slide rail 230. The lower alignment block 120 and the lower slide rail 130 are at different horizontal positions. The upper slide rail 230 and the lower slide rail 130 are symmetrical but not at the same horizontal position. The lower slider 140 and the lower slide rail 130 are... The upper slider 240 and the upper slide rail 230 are slidably connected. When the pump 400 is driven, the pump 400 will extend. During the extension process, the angle between the rotating arm 310 and the positioning shaft 330 is controlled. When the angle decreases, the equipment height decreases; when the angle increases, the equipment height increases. The sliding connection between the lower slider 140 and the lower slide rail 130 and the upper slider 240 and the upper slide rail 230 assists in the lifting and lowering of the equipment. The upper alignment block 220 has an upper alignment plate 210 installed at the end away from the positioning shaft 330. The top of the upper alignment plate 210 is provided with a positioning frame 250. The inner wall of the positioning frame 250 is provided with a drain assembly 260, which includes rollers set on the inner wall of the positioning frame 250. 263. The outer wall of the roller 263 is provided with a positioning platform 262. A plate 261 is installed on the outer wall of the positioning platform 262. A trough frame 264 is provided on the side of the plate 261 away from the positioning platform 262. A positioning groove 265 is opened on the inner wall of the trough frame 264. A shaft 269 is installed on the inner wall of the positioning groove 265. The plate 261 and the trough frame 264 are rotatably connected, and the shaft 269 and the trough frame 264 are an integrated device. The partition plate 267 is slidably connected to the positioning groove 265. When the equipment pours materials, the trough frame 264 can rotate with the plate 261 under the action of inertia, and the materials accumulated in the trough frame 264 can be directly poured out of the equipment from the bottom of the partition plate 267 through the transmission action between the partition plate 267 and the positioning groove 265.After the material is poured out, the elastic force released by spring 266 can directly push the partition 267 and reset it. Similarly, spring 268 can pull back the slot frame 264. The outer wall of shaft 269 is equipped with partition 267 and spring 266. The top end of plate 261 is equipped with one end of spring 268. Both spring 266 and spring 268 are made of spring steel. Due to the special properties of spring steel, the rigidity of spring 266 and spring 268 is stably improved, effectively extending the service life of the equipment. The other end of spring 268 is equipped with slot frame 264.

[0024] Working principle: When the equipment is needed, the worker sends a drive signal to the pump 400 through an external connection device. After receiving the signal, the pump 400 will extend and control the angle between the rotating arm 310 and the positioning shaft 330 during the extension process. When the angle decreases, the equipment height decreases; when the angle increases, the equipment height increases. The sliding connection between the lower slider 140 and the lower slide rail 130 and the upper slider 240 and the upper slide rail 230 assists in the lifting and lowering of the equipment and can drive the plate 261 to slide within the positioning frame 250, and dump the material accumulated in the trough frame 264.
