Description

Technical Field

[0001] The utility model relates to the technical field of premixed concrete unloading auxiliary equipment, in particular to a premixed concrete unloading anti-splashing device. Background Art

[0002] Ready-mixed concrete refers to a concrete mixture made of cement, aggregate, water, and admixtures and mineral admixtures added as needed in a certain proportion, which is measured and mixed at a mixing station for sale and transported to the place of use within a specified time by a transport vehicle.

[0003] The production unit of the concrete mixing station is generally set up on the second floor, and its hopper extends through the floor slab to the top of the first floor, so that the concrete can fall from the lower discharge door of the mixer on the second floor to the tank mouth of the mixer for loading. During the discharge process of the hopper of the existing concrete mixing station, there will inevitably be problems of cement mortar splashing and concrete mixture spilling, which will pollute the floor and partition walls of the production site, and it will be difficult to deal with it once it hardens. In order to avoid this problem, an extension hose is usually installed on the discharge hopper, which will not affect the normal material connection of the mixer truck and can prevent splashing to a certain extent. However, during unloading, if too much material is discharged at one time, splashing will still occur. For this reason, we propose a premixed concrete unloading anti-splashing device.

When the slide plate is squeezed and moves downward, the resistance rods 1 and 2 at the top squeeze the buffer hose. When the slide plate is not squeezed and resets upward under the action of the reset spring, the resistance rods 1 and 2 at the bottom squeeze different positions of the buffer hose, so as to avoid the buffer hose being impacted by concrete at the same position all the time, which affects its service life.

[0022] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a premixed concrete unloading anti-splash device, comprising a mounting frame 1 and a buffer hose 2, the bottom of the mounting frame 1 is provided with an auxiliary component for improving the anti-splash effect, the auxiliary component consists of a control part 3 for controlling the concrete flow rate and a driven component 4 for shielding.

[0023] The control unit 3 includes a driving motor 31, which is fixed on the top of the mounting frame 1, and a sleeve 32 is fixed on the bottom of the mounting frame 1. A movable groove 5 is provided on the surface of the sleeve 32 for the L-shaped connecting rod 42 to pass through and move up and down. A gear ring 33 is rotatably installed on the inner side of the sleeve 32. The output shaft of the driving motor 31 passes through the mounting frame 1 and is rotatably connected to the mounting frame 1. The output shaft of the driving motor 31 passes through the gear 34 and is fixedly connected to the gear 34. The gear 34 meshes with the gear ring 33. A sliding groove 310 is provided on the inner side of the sleeve 32. A slide plate 35 is slidably installed on the inner side of the sliding groove 310. A return spring 311 is fixed on the inner side of the sliding groove 310. The end of the return spring 311 away from the sliding groove 310 is fixed to the slide plate 35. A through hole 36 is provided on the slide plate 35. A resistance rod 1 37 is hinged on the surface of the slide plate 35. A resistance rod 2 38 is hinged on the end of the resistance rod 1 37 away from the slide plate 35. The end of rod 2 38 away from the interference rod 1 37 passes through the through hole 36 and is hinged on the inner side of the sleeve 32. A triangular interference block 39 is fixed to the bottom of the gear ring 33. When the ready-mixed concrete mixing equipment starts to unload, the drive motor 31 is started. The drive motor 31 drives the gear ring 33 to rotate through the gear 34, and the gear ring 33 drives the triangular interference block 39 to rotate. When the triangular interference block 39 rotates to the position of the slide plate 35, the triangular interference block 39 can push the slide plate 35 to move downward. The slide plate 35 squeezes the interference rod 1 37 and the interference rod 2 38, so that the hinged position of the interference rod 1 37 and the interference rod 2 38 is in contact with the surface of the buffer hose 2, and the buffer hose 2 is squeezed, so that the buffer hose 2 is deformed, thereby reducing the area of ​​the internal passage, thereby reducing the flow speed of the concrete when it passes through, avoiding the rapid unloading of a large amount of concrete and causing splashing, and cooperating with the buffer hose 2 to improve the anti-splashing effect.

[0024] There are two groups of through holes 36, resistance rods 1 37 and resistance rods 2 38, and the two groups of through holes 36, resistance rods 1 37 and resistance rods 2 38 are symmetrically arranged with the transverse center line of the slide plate 35 as the symmetry axis. When the slide plate 35 is squeezed and moves downward, the resistance rods 1 37 and 38 at the top squeeze the buffer hose 2. When the slide plate 35 is not squeezed and resets upward under the action of the reset spring 311, the resistance rods 1 37 and 38 at the bottom squeeze different positions of the buffer hose 2 to avoid the buffer hose 2 being constantly impacted by concrete at the same position, which affects its service life.

[0025] The driven assembly 4 includes a circular ring 41, which is slidably mounted on the inner side of the sleeve 32. An L-shaped connecting rod 42 is fixed on the surface of the circular ring 41. The L-shaped connecting rod 42 penetrates the sleeve 32 and is slidably connected to the sleeve 32. A support rod 43 is hinged on the surface of the sleeve 32. A connecting ring 45 is fixed to the end of the support rod 43 away from the sleeve 32. A rubber cloth 44 is fixed to the surface of the connecting ring 45. The end of the rubber cloth 44 away from the connecting ring 45 is fixed to the surface of the sleeve 32. When the gear ring 33 rotates, due to the gear ring 33 has a certain rotation speed, thereby ensuring that it can always cause resistance to a certain group of slide plates 35, so that there is always a group of slide plates 35 that can push the ring 41 to move downward, the ring 41 drives the L-shaped connecting rod 42 to move downward, the L-shaped connecting rod 42 resists on the support rod 43, so that the support rod 43 swings downward at the position hinged with the sleeve 32, the support rod 43 and the connecting ring 45 can pull the rubber cloth 44 to make it open, so as to play a shielding role, further improving the anti-splashing effect.

[0026] When installing the entire device, after installing the buffer hose 2 at the discharge port of the ready-mixed concrete mixing equipment, the mounting frame 1 is installed on the discharge port of the ready-mixed concrete mixing equipment using bolts, and the drive motor 31 is connected to the external wire to power the drive motor 31.

[0027] When unloading, the buffer hose 2 is provided to ensure that the concrete material can accurately enter the mixer truck, thereby preventing splashing.

[0028] While unloading, by turning on the driving motor 31, the driving motor 31 drives the gear ring 33 to rotate through the gear 34, and the gear ring 33 drives the triangular resistance block 39 to rotate. When the triangular resistance block 39 rotates to the position of the slide plate 35, the triangular resistance block 39 can push the slide plate 35 to move downward, and the resistance rod 1 37 and the resistance rod 2 38 at the top squeeze the buffer hose 2. When the slide plate 35 is not squeezed and resets upward under the action of the reset spring 311, the resistance rod 1 37 and the resistance rod 2 38 at the bottom squeeze the buffer hose 2 at different positions, so that the buffer hose 2 is deformed, thereby reducing the area through which it passes, thereby reducing the flow speed of the concrete when it passes, avoiding the rapid unloading of a large amount of concrete and causing splashing, and cooperating with the buffer hose 2 to improve the anti-splashing effect.

[0029] When the gear ring 33 rotates, since the gear ring 33 has a certain rotation speed, it can ensure that it can always cause resistance to a certain group of slide plates 35, so that there is always a group of slide plates 35 that can push the ring 41 to move downward, and the ring 41 drives the L-shaped connecting rod 42 to move downward. The L-shaped connecting rod 42 resists on the support rod 43, so that the support rod 43 swings downward at the position hinged with the sleeve 32, and the support rod 43 and the connecting ring 45 can pull the rubber cloth 44 to make it open, so as to play a shielding role, further improving the anti-splashing effect.

[0030] After the unloading is completed, it is only necessary to turn off the driving motor 31 and stop the gear ring 33 from rotating. At this time, the staff only needs to check the status of the rubber cloth 44. If the rubber cloth 44 is still in the open state, it is only necessary to start the driving motor 31 to drive the gear ring 33 to rotate a certain angle, so that the triangular resistance block 39 no longer resists the slide plate 35, so that the ring 41 is no longer pushed by the slide plate 35, and the L-shaped connecting rod 42 can no longer apply pressure to the support rod 43. Under the elastic action of the rubber cloth 44 itself, the support rod 43 swings upward at the position hinged with the sleeve 32 to achieve the reset of the device.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
