Description

Technical Field

[0001] The utility model belongs to the technical field of concrete mixing stations, and more specifically, particularly relates to an automatic water level control device for a concrete mixer. Background Art

[0002] A concrete mixing station is a building material manufacturing device composed of five major component systems, namely a mixing main machine, a material weighing system, a material conveying system, a material storage system, and a control system, as well as other auxiliary facilities. The main working principle is that with cement as the binding material, raw materials such as sand, gravel, lime, and cinder are mixed and stirred, and finally made into concrete to be used as wall materials in construction production. Since the concrete mixing station was put into use, it has been playing an important role in the construction building materials industry in our country, which is of course determined by the superior characteristics of the concrete mixing station itself.

[0003] In the production of concrete, usually different amounts of water need to be poured in according to different raw materials to mix and stir them in the mixer to form concrete. However, if the pouring ratio of water and the ratio of the poured raw materials are incorrect, it will cause the concrete to be too thin or too thick, resulting in the inability to form concrete. Currently, generally, manual control of the water addition amount is mostly used, and it is impossible to independently control the water amount, which is time-consuming and laborious, and the work efficiency is low.

[0004] Regarding the problems in the related technology, no effective solution has been proposed yet. Summary of the Utility Model

[0030] Please refer to Figures 1-6 As shown, the present utility model is an automatic water level control device for a concrete mixer, including a housing 1. A support assembly 2 is installed at the bottom of the housing 1. A water inlet hopper 3 communicating with the inside thereof is installed at the upper end of the housing 1. A water outlet pipe 4 communicating with the inside thereof is installed at the bottom of the housing 1. A water level sensor 5 is installed at the top of the inner cavity of the housing 1. A driving assembly 6 is installed inside the housing 1. A water level plate 7 is installed on the driving assembly 6. An opening and closing assembly 8 is installed on the water level plate 7.

[0031] The water inlet hopper 3 is used to pour water into the housing 1. The driving assembly 6 can drive the water level plate 7 to move in the inner cavity of the housing 1, so that the amount of water that can be poured into the inner cavity of the housing 1 changes. When the water contacts the water level sensor 5, the water level sensor 5 can control the opening and closing assembly 8 to change its form, so that the water can be transported out through the water outlet pipe 4.

[0032] In actual use, through the water inlet hopper 3, water can be poured into the inner cavity of the housing 1. And through the driving assembly 6, the water level plate 7 can be driven to move in the housing 1, so that the amount of water that can be poured into the housing 1 is determined by the inner cavity space of the housing 1 left above the water level plate 7, so that the water level can be adjusted, and various water level adjustments can be made for proportioning. When the water has filled the inside of the housing 1 and reached the top surface of the inner cavity of the housing 1, the water level sensor 5 will contact the water, thereby triggering the induction to drive the opening and closing assembly 8 to move, so that the water level plate 7 is no longer in a closed state, and the water can be discharged through the water outlet pipe 4 to the outside and enter the external mixer to be mixed and stirred with the concrete raw materials, so as to ensure that the amount of water and the raw material ratio are correct and ensure the quality of the concrete.

[0033] In this utility model, the amount of water that can be poured into the inner cavity of its housing 1 is determined by the inner cavity space of the housing 1 left above the water level plate 7, so as to achieve correct control of the amount of water and its raw material ratio. The driving assembly 6 can drive the water level plate 7 to move up and down in the inner cavity of the housing 1, so that the amount of water that can be poured into the inner cavity of the housing 1 can change to suit various ratio operations and improve the applicable scenarios. When the water fills the housing 1, it will trigger the water level sensor 5, and then the opening and closing assembly 8 will be activated by the water level sensor 5 to move, changing the water level plate 7 to an unclosed state, and discharging the water to the outside through the water outlet pipe 4, thus achieving that the device can automatically control the water level, control the amount of water according to requirements, avoid incorrect ratio of water and raw materials, and improve the quality of concrete.

[0034] In one embodiment, for the above-mentioned water level plate 7, a sealing gasket 9 is fixedly installed on the surface of the water level plate 7, positioning blocks 10 are symmetrically installed on the inner wall of the housing 1, the water level plate 7 is slidably installed on the positioning blocks 10, a water outlet groove 11 is formed through the upper surface of the water level plate 7, and the opening and closing assembly 8 can completely close the water outlet groove 11.

[0035] Installing the sealing gasket 9 on the surface of the water level plate 7 can improve its sealing performance, prevent water from leaking through the gaps to the lower part of the water level plate 7, causing incorrect ratio of the amount of water, and improve the accuracy of the amount of water. The positioning blocks 10 can make the water level plate 7 slide more smoothly under the drive of the driving assembly 6, improving the stability. When the water has filled the inner cavity space of the housing 1 left above the water level plate 7, it will contact the water level sensor 5 installed on the top surface of the inner cavity of the housing 1, and then the opening and closing assembly 8 will be activated by the water level sensor 5, so that the opening and closing assembly 8 no longer closes the water outlet groove 11, and the water can fall to the lower part of the inner cavity of the housing 1 through the water outlet groove 11 and be transported to the outside through the water outlet pipe 4.

[0036] In one embodiment, for the above-mentioned driving assembly 6, the driving assembly 6 includes a motor 12, the motor 12 is installed at the bottom of the housing 1, a screw rod 13 is installed on the axis of the motor 12, the upper end of the screw rod 13 penetrates through the housing 1 and extends into the interior, and the water level plate 7 is threadedly installed through the screw rod 13.

[0037] By driving the motor 12, the screw rod 13 can be driven to rotate, thereby driving the water level plate 7 to slide on the positioning blocks 10, changing the inner cavity space of the housing 1 left above the water level plate 7, and further enabling the amount of water that can meet different ratio requirements and be applicable to various scenarios.

[0038] In one embodiment, for the above-mentioned water outlet tank 11, fixing plates 14 are installed on both sides of the water outlet tank 11, fixing grooves 15 are formed in the fixing plates 14, and the opening and closing assembly 8 is slidably installed in the fixing grooves 15.

[0039] By installing the fixing plates 14 on both sides of the water outlet tank 11 and forming the fixing grooves 15 in the fixing plates 14, the opening and closing assembly 8 can slide in the fixing grooves 15, thereby changing the closed state of the water outlet tank 11, and the water is transported to the outside through the water outlet pipe 4.

[0040] In one embodiment, for the above-mentioned opening and closing assembly 8, the opening and closing assembly 8 includes an opening and closing plate 16. The opening and closing plate 16 is slidably installed in the fixing groove 15, and the opening and closing plate 16 can completely close the water outlet tank 11.

The electric push rod 18 is installed on the bottom surface of the water level plate 7, and the telescopic end of the electric push rod 18 is installed on the installation plate 17.

[0041] When the water fills the inner cavity space of the housing 1 left above the water level plate 7, it will contact the water level sensor 5 installed on the top surface of the inner cavity of the housing 1. Thus, the electric push rod 18 is started through the water level sensor 5, and the electric push rod 18 drives the opening and closing plate 16 to slide in the fixing groove 15 through the installation plate 17, so that the opening and closing plate 16 no longer closes the water outlet tank 11. The water in the inner cavity space of the housing 1 left above the water level plate 7 can be discharged from the lower part of the inner cavity of the housing 1 through the water outlet tank 11, and then transported to the outside through the water outlet pipe 4, achieving that the device can independently transport the proportionally stored water to the external mixer, saving time and effort and improving production efficiency.

[0042] In one embodiment, for the above-mentioned housing 1, an observation window 19 is installed on one side of the housing 1, and a scale 20 is engraved on the same side of the housing 1 as the observation window 19.

[0043] Through the installed observation window 19 and the engraved scale 20, it is convenient for the operator to check the position of the water level plate 7, so as to accurately adjust the inner cavity space of the housing 1 left above the water level plate 7, and accurately adjust the amount of water poured into the inner cavity of the housing 1 according to the requirements.

[0044] In one embodiment, for the above-mentioned water outlet pipe 4, a flange 21 is installed at one end of the water outlet pipe 4.

[0045] Through the flange 21, the water outlet pipe 4 can be connected to the conveying pipe of the external mixer, so that the water inside the housing 1 can be transported into the mixer and stirred and mixed with the raw materials to form concrete.

[0046] In summary, by means of the above technical solution of the present utility model, water can be poured into the inner cavity of the housing 1 through the water inlet hopper 3, and the amount of water that can be poured into the inner cavity of the housing 1 is determined by the inner cavity space of the housing 1 left above the water level plate 7. Moreover, the installation of the sealing gasket 9 on the surface of the water level plate 7 can improve its sealing performance, prevent water from leaking through the gap to the lower part of the water level plate 7, and avoid incorrect water volume ratio, thus improving the accuracy of the water volume. When it is necessary to change the inner cavity space of the housing 1 left above the water level plate 7 to change the proportioned water volume, the motor 12 can be driven, which can drive the screw 13 to rotate, thereby driving the water level plate 7 to slide on the positioning block 10, changing the inner cavity space of the housing 1 left above the water level plate 7, so as to meet the water volume requirements of different proportions and be applicable to various scenarios. After the water fills the inner cavity space of the housing 1 left above the water level plate 7, it will contact the water level sensor 5 installed on the top surface of the inner cavity of the housing 1, and then the electric push rod 18 is started through the water level sensor 5, so that the electric push rod 18 drives the opening and closing plate 16 to slide in the fixed groove 15 through the mounting plate 17, so that the opening and closing plate 16 no longer closes the water outlet groove 11, and the water in the inner cavity space of the housing 1 left above the water level plate 7 can be discharged from the water outlet groove 11 to the lower part of the inner cavity of the housing 1, and then be transported to the outside through the water outlet pipe 4, achieving that the device can independently transport the proportionally stored water to the external mixer, saving time and effort and improving production efficiency. Moreover, through the observation window 19 and the engraved scale 20, it is also convenient for the operator to check the position of the water level plate 7 to accurately adjust the inner cavity space of the housing 1 left above the water level plate 7, so as to accurately adjust the amount of water poured into the inner cavity of the housing according to the requirements.
