[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a liquid metering device for concrete mixing, which includes a liquid tank 1, a metering valve 6 connected to the lower end of the liquid tank 1, a shaft tube 7 rotatably connected to the outlet of the metering valve 6, and telescopic hoses 9 connected to both sides of the shaft tube 7, with a liquid outlet nozzle 11 connected to the end of the telescopic hose 9.

[0024] When adding liquid to the concrete mixer using this device, the liquid in the liquid tank 1 is metered out through the metering valve 6, and the liquid flows into the shaft tube 7, the telescopic hose 9 and the liquid outlet nozzle 11, so that the liquid can be meteredly added to the concrete being mixed through the liquid outlet nozzle 11.

[0025] In this embodiment, reciprocating sliding drive assemblies are provided on both sides of the shaft tube 7. Each reciprocating sliding drive assembly includes a concave rail 8, a sliding plate 12, a first forward and reverse motor 13, and a first lead screw 14. The concave rail 8 is fixed to the outside of the shaft tube 7. The sliding plate 12 is slidably connected to the concave rail 8. The first forward and reverse motor 13 is fixed to one end of the inner side of the concave rail 8. One end of the first lead screw 14 is connected to the power end of the first forward and reverse motor 13, and the other end of the first lead screw 14 is rotatably connected to the other end of the inner side of the concave rail 8. The sliding plate 12 is threadedly sleeved with the first lead screw 14.

[0026] When liquid is added quantitatively to the mixed concrete through the liquid outlet nozzle 11, the first forward and reverse motor 13 works and drives the first lead screw 14 to rotate back and forth. The first lead screw 14 will drive the sliding plate 12 to slide back and forth along the concave rail 8. At the same time, the sliding plate 12 will drive the liquid outlet nozzle 11 to move back and forth together, and the telescopic hose 9 will extend and retract. Therefore, it is beneficial to drive the liquid outlet nozzle 11 to move back and forth to add liquid through the reciprocating sliding drive assembly, so as to ensure the uniformity of liquid addition.

[0027] In this embodiment, a reciprocating rotary drive assembly is provided below the liquid tank 1. The reciprocating rotary drive assembly includes a reciprocating motor 15, a main gear 16, and a secondary gear 17. The reciprocating motor 15 is fixed to the lower end of the liquid tank 1. The main gear 16 is connected to the power end of the reciprocating motor 15. The secondary gear 17 is fixedly sleeved around the shaft tube 7 and meshes with the main gear 16.

[0028] Furthermore, the reciprocating motor 15 drives the main gear 16, the auxiliary gear 17, the shaft tube 7, the reciprocating sliding drive assembly, and the liquid outlet nozzle 11 to rotate back and forth together, and the range of reciprocating rotation does not exceed 360 degrees. Therefore, the reciprocating rotation drive assembly is conducive to driving the liquid outlet nozzle 11 to rotate back and forth to add liquid. In summary, this is conducive to controlling the back and forth movement and reciprocating rotation of the liquid outlet nozzle 11 to add liquid, which is conducive to adding liquid more evenly to the concrete being mixed, thereby effectively saving the time for the concrete to be mixed evenly.

[0029] In this embodiment, support plates 4 are provided on both sides of the lower end of the liquid tank 1. Support rods 3 are fixed to the upper end of the support plates 4. Top plates 2 are fixed to the upper ends of the two support rods 3. The top plates 2 have vertically penetrating movable openings 10. Height adjustment components are provided above the support plates 4. Each height adjustment component includes a lifting plate 20, a second forward and reverse motor 18, and a second lead screw 19. The lifting plates 20 are fixed to the outside of the liquid tank 1 and are slidably sleeved with the adjacent support rods 3. The second forward and reverse motor 18 is fixed to the upper end of the support plate 4. One end of the second lead screw 19 is connected to the power end of the second forward and reverse motor 18, and the other end of the second lead screw 19 is rotatably connected to the lower end of the top plate 2. The lifting plates 20 and the second lead screw 19 are threadedly sleeved.

[0030] By setting up a height adjustment component, when it is necessary to adjust the liquid addition height of the liquid outlet nozzle 11, the two second forward and reverse motors 18 work simultaneously. The second forward and reverse motors 18 drive the second lead screw 19 to rotate forward or reverse. The second lead screw 19 will drive the lifting plate 20 to slide down or down along the support rod 3. At the same time, the lifting plate 20 will drive the liquid tank 1 and the liquid outlet nozzle 11 to move up and down together. Therefore, it is convenient to adjust the liquid addition height of the liquid outlet nozzle 11, which is conducive to quantitative liquid addition for stirring equipment of various heights, effectively ensuring the applicability of the device.

[0031] In this embodiment, the lower end of each support plate 4 is rotatably connected to casters 5. By providing casters 5 and rotating them, the quantitative dispensing device can be easily moved, and the liquid nozzle 11 can be easily moved above the stirring equipment where quantitative liquid dispensing is required.

[0032] The liquid metering device of this utility model is used in the mixing process of concrete production. The device is moved by the rotation of the universal wheel 5, and the liquid outlet nozzle 11 is moved to the top of the mixing equipment. Then, the liquid in the liquid tank 1 is metered out through the metering valve 6. The liquid flows into the shaft tube 7, the telescopic hose 9 and the liquid outlet nozzle 11. Then, the liquid is meteredly added to the concrete being mixed through the liquid outlet nozzle 11.

[0033] Simultaneously, the aforementioned first forward and reverse motor 13 operates and drives the first lead screw 14 to rotate back and forth. The first lead screw 14 drives the sliding plate 12 to slide back and forth along the concave rail 8. At the same time, the sliding plate 12 drives the liquid nozzle 11 to move back and forth to add liquid. The reciprocating motor 15 drives the main gear 16, the secondary gear 17, the shaft tube 7, the reciprocating sliding drive assembly, and the liquid nozzle 11 to rotate back and forth, thereby driving the liquid nozzle 11 to rotate back and forth to add liquid. The second forward and reverse motor 18 drives the second lead screw 19 to rotate forward or reverse. The second lead screw 19 drives the lifting plate 20 to slide down or down along the support rod 3. At the same time, the lifting plate 20 drives the liquid tank 1 and the liquid nozzle 11 to move up and down together, thereby adjusting the liquid addition height of the liquid nozzle 11.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
