Description

Technical Field

[0001] This utility model relates to the field of material distributor technology, specifically to a roller-compacted concrete receiving and distributing device. Background Technology

[0002] When constructing roller-compacted concrete in a large silo, a single conveyor belt with one receiving hopper is often insufficient to meet the concrete strength requirements. Multiple conveyor belts (including matching receiving hoppers) must be arranged to meet the concrete pouring strength requirements. This increases the workload of the silo equipment and delays the construction period. In addition, arranging multiple conveyor belt systems in the silo brings more safety hazards to the operation.

[0003] Among them, announcement number CN206052721 U discloses a roller-compacted concrete receiving and distributing device, including a distributing device and a receiving device. The receiving device is located below the distributing device and includes two or more horizontally arranged receiving hoppers. The distributing device includes a receiving hopper and two or more distributing hoppers. The distributing hoppers are located below the bottom of the receiving hoppers and are connected to the receiving hoppers. Each receiving hopper of the receiving device is connected to at least one distributing hopper. However, this technical solution still has defects:

[0004] In this technical solution, since the receiving hopper needs to supply material to two distributing hoppers at the same time and the discharge stroke is short, the material is prone to accumulate at the discharge port of the receiving hopper, causing blockage at the discharge port and affecting normal discharge operation. Utility Model Content

[0005] In view of the problems existing in the current roller-compacted concrete receiving and distributing device, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a roller compacted concrete receiving and distributing device, which solves the problem in the prior art where the receiving hopper needs to supply material to two distributing hoppers at the same time, and the discharge stroke is short, so the material is easy to accumulate at the discharge port of the receiving hopper, causing the discharge port to be blocked and affecting the normal discharge operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A roller-compacted concrete receiving and distributing device includes a receiving hopper and a distributing hopper. Two distributing hoppers are symmetrically arranged on the lower side of the receiving hopper. Side plates are fixedly installed on both sides of the front side of the receiving hopper. A crossbar is rotatably sleeved inside the two side plates. A striking strip is fixedly connected to the close end of the two crossbars. Rotating rods are rotatably installed inside the lower end of the two distributing hoppers. Impellers are fixedly sleeved on the rod walls of the rotating rods. One end of the rotating rod extends to the outside of the distributing hopper. A transmission mechanism for driving the crossbars to rotate is provided at the outer end of the rotating rod.

[0009] Preferably, the transmission mechanism includes a gear and a rack. A fixed ring is fixedly provided on the lower outer wall of the receiving hopper. A sliding rod is movably sleeved inside the fixed ring. The rack is fixedly provided on the upper end of the sliding rod. The gear is fixedly sleeved on the end of the crossbar away from the striking bar. The gear and the rack are meshed together. A movable ring is fixedly provided on the lower end of the sliding rod. A turntable is fixedly sleeved on the outer end of the rotating rod. A round pin is eccentrically provided on the front side of the turntable. One end of the round pin passes through the movable ring.

[0010] Preferably, a retaining ring is fixedly sleeved at the front end of the round pin.

[0011] Preferably, the cross-sections of the fixing ring and the slide rod are both rectangular.

[0012] Preferably, the surface of the slide rod and the inner wall of the fixing ring are both coated with a wear-resistant coating.

[0013] Preferably, both striking strips are rubber strips.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] This invention involves material entering the distribution hopper from the receiving hopper and flowing out from the bottom of the distribution hopper. During this process, the material drives the impeller to rotate, which in turn drives the rotating rod to rotate. The rotating rod drives the turntable to rotate, which in turn drives the round pin to rotate around the rotating rod as an axis. This causes the round pin to push the movable ring to move vertically, which in turn causes the sliding rod to move up and down. During this process, the sliding rod drives the rack to move back and forth, which in turn drives the gear to rotate back and forth. This causes the striking bar to repeatedly strike the receiving hopper, causing the material inside the receiving hopper to vibrate and effectively preventing material accumulation and blockage of the receiving hopper.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a roller-compacted concrete receiving and distributing device.

[0024] Reference Figure 1-3 A roller-compacted concrete receiving and distributing device includes a receiving hopper 1 and a distributing hopper 2. The two distributing hoppers are symmetrically arranged on the lower side of the receiving hopper 1. Side plates 3 are fixedly installed on both sides of the front side of the receiving hopper 1. A crossbar 4 is rotatably sleeved inside the two side plates 3. A striking strip 5 is fixedly connected to the close end of the two crossbars 4. The striking strips 5 on both sides are rubber strips to prevent damage to the receiving hopper 1 as much as possible. Rotating rods 8 are rotatably installed inside the lower end of the two distributing hoppers 2. Impellers 9 are fixedly sleeved on the rod wall of the rotating rod 8. One end of the rotating rod 8 extends to the outside of the distributing hopper 2.

[0025] A transmission mechanism for driving the crossbar 4 to rotate is provided at one end of the outer side of the rotating rod 8. The transmission mechanism includes a gear 6 and a rack 7. A fixing ring 10 is fixedly provided on the lower outer wall of the receiving hopper 1. A sliding rod 11 is movably sleeved inside the fixing ring 10. The cross-sections of both the fixing ring 10 and the sliding rod 11 are rectangular, so that the fixing ring 10 cannot rotate, i.e., it can slide stably. The surface of the sliding rod 11 and the inner wall of the fixing ring 10 are coated with a wear-resistant coating to improve the wear resistance of the sliding rod 11 and the fixing ring 10. For grinding performance, rack 7 is fixedly set at the upper end of slide rod 11, gear 6 is fixedly sleeved on the end of cross bar 4 away from striking bar 5, gear 6 and rack 7 are meshed and connected, movable ring 12 is fixedly set at the lower end of slide rod 11, turntable 13 is fixedly sleeved on the outer end of rotating rod 8, round pin 14 is eccentrically set on the front side of turntable 13, one end of round pin 14 passes through movable ring 12, and a retaining ring is fixedly sleeved on the front end of round pin 14 to prevent round pin 14 from slipping out of movable ring 12 as much as possible.

[0026] In this invention, during use, after the material enters the distributing hopper 2 from the receiving hopper 1, it flows out from the lower end of the distributing hopper 2. During this process, the material pushes the impeller 9 to rotate, which causes the rotating rod 8 to rotate. The rotating rod 8 drives the turntable 13 to rotate, which causes the round pin 14 to rotate around the rotating rod 8 as an axis. This causes the round pin 14 to push the movable ring 12 to move vertically, which causes the sliding rod 11 to move up and down repeatedly. During this process, the sliding rod 11 drives the rack 7 to move back and forth, which causes the rack 7 to drive the gear 6 to rotate back and forth. This causes the striking bar 5 to repeatedly strike the receiving hopper 1, causing the material inside the receiving hopper 1 to vibrate, effectively preventing the material from accumulating and causing blockage in the receiving hopper 1.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
