Description

Technical Field

[0001] This invention relates to the field of material discharge hopper technology, and particularly to concrete discharge hoppers. Background Technology

[0002] In a concrete mixing plant production line, the discharge hopper is a core supporting equipment that connects to the discharge end of the mixing host and completes the unloading and transportation of concrete mixer trucks. It mainly undertakes the work of receiving, guiding and discharging finished concrete materials; its installation height and discharge position directly determine the receiving effect of the mixer trucks and the quality of the finished concrete.

[0003] Most existing concrete mixing plants have fixed hoppers with a fixed height after installation. This makes it difficult to adjust the height flexibly and adapt to concrete trucks of different heights. As a result, the vertical distance between the bottom of the hopper and the receiving port of various trucks cannot be standardized, which may lead to excessive distance. This causes material to scatter and aggregate to spill during truck receiving operations. Summary of the Invention

[0035] The specific usage and function of this embodiment: In this invention, the entire equipment is first fixedly installed at the discharge end of the concrete mixing host by installing the flange frame 101, thus completing the overall equipment fixation; after the concrete mixer truck stops at the designated receiving position, the staff can issue adjustment commands through a remote terminal, and the wireless communication module transmits the signals to the microcontroller; the microcontroller activates the infrared ranging probe 3012 to detect the distance between the measuring plate 3011 in real time, accurately obtains the current height position data of the moving hopper 501, and controls the servo motor 305 to start in combination with the preset standard receiving height parameters; the servo motor 305 drives the double-headed screw 304 to rotate, and synchronous transmission is achieved through the chain of the sprocket 306, driving the adjusting seats 308 on both sides. The material slides smoothly along the dovetail grooves on the inner side of the adjusting frame 302 and the reinforcing plate 307. This, combined with the rotatable adjusting plate 309 at the bottom of the adjusting seat 308, drives the horizontal frame 3010 to adjust its height. Ultimately, the movable hopper 501 connected to the bottom of the horizontal frame 3010 is precisely adjusted to the optimal receiving position for the current tank truck height, minimizing the vertical drop between the hopper outlet and the tank truck receiving port, thus accommodating the receiving needs of tank trucks of different heights. After height adjustment, the hydraulic cylinder 107 is activated. The hydraulic cylinder 107, fixed on the outer side of the hopper 1, rotates around the fixed shaft 106 and extends its telescopic end. Through the driving block 108, it pushes the driving arm 105 to rotate, causing the symmetrically arranged opening and closing shafts 103 and the baffle plate 104 to simultaneously rotate and open the discharge port, allowing concrete to be discharged. Material falls from the fixed hopper 1 into the lower movable hopper 501. During the material's descent, the upper buffer frame 504 and lower buffer frame 503, which are staggered inside the movable hopper 501, provide step-by-step flow guidance and buffering. Combined with the elastic buffering effect of the spring telescopic rod 502, this effectively reduces the material's falling speed, balances the falling rate of coarse and fine aggregates, and prevents stratification and segregation of concrete materials due to high-speed falling. During operation, the spring components between the connecting frame 403 and the limiting seat 404 work together with the overall structure to absorb the impact and vibration of the material, improving the stability of the equipment. Throughout the unloading process, the anti-blocking component 2 operates synchronously. The motor device on the outside of the fixed cylinder frame 201 drives the horizontal shaft 202 to rotate, which is controlled by the bevel gear A. The meshing transmission between 203 and bevel gear B205 drives the reciprocating screw 204 to rotate continuously. The reciprocating screw 204 drives the sliding ring 206 to reciprocate through the spiral groove and connecting block 207, which in turn drives the sliding rod 208 to slide up and down continuously along the bottom of the T-shaped fixed cylinder frame 201. This, in turn, drives the scraping ring frame 2010 at the bottom to perform reciprocating scraping action along the inner wall of the bottom of the fixed hopper 1, which scrapes away the viscous concrete and aggregates that are adhering to and accumulating on the inner wall of the hopper in real time, keeping the discharge port unobstructed and avoiding material accumulation and solidification that could cause blockage. This achieves an automated operation mode of unloading and clearing blockages simultaneously. When the tanker truck finishes receiving the material and the unloading operation is completed, the hydraulic cylinder 107 is controlled to retract, which drives the two sets of baffle plates 104 to close synchronously, cutting off the material discharge.
