Description

Technical Field

[0002] Concrete, abbreviated as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering. When pouring concrete on the river bank, since concrete tank trucks cannot reach it directly, concrete needs to be transported through a transfer device.

[0003] When the existing concrete transfer device is in use, a transmission structure is provided on it to control the valve to open and close, but there are too many links in the transmission structure. If any link fails, the valve cannot be controlled, resulting in reduced flexibility in the use of the device. For example, a concrete bucket with controllable flow rate disclosed in application number CN202020555136.X rotates the turntable counterclockwise so that the second shaft drives the worm to rotate counterclockwise, so that the worm wheel drives the first shaft to rotate clockwise stably and accurately, so that the circular gear engages with the teeth on the front of the connecting rod, so that the connecting rod drives the concrete baffle and the convex bar to move upward stably and slowly along the concave slide rail, so that the concrete baffle can conveniently and accurately control the concrete flow rate. However, this patent requires a large number of transmission structures to realize the movement of the concrete baffle. Once a link in the transmission structure fails, the concrete baffle cannot be moved, resulting in reduced flexibility in the use of the device.

An end block 8 is fixedly connected to both sides of the rotating shaft 4, and a bolt 9 is fixedly connected to one side of the two end blocks 8. The two bolts 9 are respectively passed through two limited movable grooves 11, and one end of the two bolts 9 passing through the limited movable grooves 11 is threadedly connected with a hand-tightened nut 10.

[0025] By adopting the above technical scheme, when automatic opening and closing control is performed, the rotating shaft 4 and the discharge valve plate 3 are driven to rotate by the No. 1 motor 5. The discharge valve plate 3 can control the opening and closing of the discharge pipe 2 while rotating. By controlling the rotation angle of the discharge valve plate 3, the discharge flow rate of the concrete can be controlled; when manual opening and closing control is performed, the rotating shaft 4 and the discharge valve plate 3 are rotated by the rotating disk 6. At this time, the bolt 9 moves along the limiting movable groove on the limiting disk 7. After the discharge valve plate 3 is rotated to a suitable position, the hand-tightened nut 10 is tightened along the bolt 9, thereby fixing the rotating shaft 4 and the discharge valve plate 3 at the current position.

[0026] In one aspect of the present embodiment, a loading horizontal plate 12 is fixedly connected to the middle of the top of the storage hopper 1, and flip plates 13 are hingedly provided on both sides of the top of the storage hopper 1. One end of the two flip plates 13 overlaps with the two ends of the loading horizontal plate 12 respectively, and the tops of the two flip plates 13 are fixedly connected with handles 14.

[0029] Refer to the instruction manual Figure 1-5 When using the utility model, firstly, the flap plate 13 on the top of the storage hopper 1 is opened by the handle 14, and then concrete is poured into the storage hopper 1. Then, the storage hopper 1 is lifted to a designated position by a crane. After the storage hopper 1 is placed stably, the No. 1 motor 5 and the No. 2 motor 16 are started, and the stirring shaft 17 and the stirring blade 18 are driven by the No. 2 motor 16 to rotate, so as to stir the concrete inside the storage hopper 1 to improve the fluidity of the concrete. The No. 1 motor 5 drives the rotating shaft 4 and the discharge valve plate 3 to rotate. While the discharge valve plate 3 rotates, the discharge pipe 2 can be opened and closed. By controlling the discharge valve plate 3, the feeding flow rate of concrete can be controlled. When the connection between the No. 1 motor 5 and the rotating shaft 4 fails, the connection between the No. 1 motor 5 and the rotating shaft 4 is first canceled, and then the rotating shaft 4 and the feeding valve plate 3 are rotated by the rotating disk 6. When the feeding valve plate 3 is rotated to a suitable position, the hand-tightened nut 10 is tightened along the bolt 9 to fix the rotating shaft 4 and the feeding valve plate 3 at the current position. The utility model has both automatic opening and closing control and manual opening and closing control. When the automatic opening and closing control fails, the manual opening and closing control can be switched, which is beneficial to improving the flexibility of the device.
