Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete spraying machine technology, and in particular to a concrete spraying machine. Background Technology
[0002] A concrete spraying machine is a piece of equipment used for concrete spraying operations, widely used in tunnels, underground engineering, mining, construction, and other fields. Its main function is to spray concrete slurry onto the construction surface under high pressure, forming a uniform concrete layer, thereby improving construction efficiency, enhancing construction quality, and enabling construction in complex terrains and environments. Concrete spraying machines are generally divided into two types: dry spraying and wet spraying. Dry spraying concrete spraying machines: In this type of spraying machine, dry concrete is fed into the nozzle along with air, and water is then added at the nozzle for mixing. The advantage of this equipment is that the water volume can be adjusted on-site, flexibly adapting to different construction needs. The disadvantage is that it is prone to dust pollution, requiring additional dust collection equipment. Wet spraying concrete spraying machines: In wet spraying equipment, the concrete is mixed with water before being transported, so it can be sprayed directly. The advantages of this equipment are reduced dust pollution, more stable concrete quality, and higher construction efficiency.
[0003] In existing concrete spraying machines, when concrete needs to be sprayed, workers usually hold the nozzle by hand. After prolonged use, fatigue can easily occur, making it difficult to control the spray height and angle, thus making the machine inconvenient to use. Therefore, we propose a concrete spraying machine to solve the above-mentioned problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where, in practical use, concrete spraying is typically done by workers holding the nozzle by hand, which can lead to fatigue after prolonged use and difficulty in controlling the spray height and angle, resulting in inconvenience in operation. Therefore, this invention proposes a concrete spraying machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A base and a processing tank, wherein the processing tank is fixedly connected to the top of the base;

A limiting groove is opened on the front side of the vertical rod, and the limiting plate engages with the limiting groove. The nozzle, the conveying pump, and the processing tank are connected.
[0009] A limiting mechanism is connected to a limiting plate, and the limiting mechanism is used to fix the nozzle and the control motor.
[0010] As a preferred embodiment of this utility model, the limiting mechanism includes: a control plate, a push rod, an unlocking rod, and a transmission rod;
[0011] The push rod is slidably connected to the bottom of the lifting plate, the unlocking rod is rotatably connected to the bottom of the push rod, the control plate is fixedly connected to the left side of the push rod, the transmission rod is fixedly connected to the rear side of the limiting plate, and the top of the unlocking rod is rotatably connected to the bottom of the transmission rod.
[0012] As a preferred embodiment of this utility model, the bottom of the lifting plate is fixedly connected to a support frame, and both the push rod and the transmission rod pass through the support frame.
[0013] In a preferred embodiment of this utility model, a push spring is fixedly connected to the left side of the support frame, and the left side of the push spring is fixedly connected to the right side of the control panel.

The nozzle can easily spray the concrete. The limiting mechanism can easily drive the limiting plate to move.

[0018] 2. When the control panel moves, it will drive the push rod to move laterally. At the same time, the movement of the push rod will push the unlocking rod. At this time, the movement of the unlocking rod will push the transmission rod to move backward. When the transmission rod moves, it will pull the limit plate to move.

When the control plate 10 moves, it will drive the push rod 11 to move laterally, and at the same time, the movement of the push rod 11 will push the unlocking rod 14. At this time, the movement of the unlocking rod 14 will push the transmission rod 15 to move backward, and the movement of the transmission rod 15 will pull the limiting plate 16 to move. When the limiting plate 16 moves, it will disengage from the limiting groove, thereby unlocking the lifting plate 7 and facilitating the movement of the nozzle 9.
[0033] As a preferred embodiment of this utility model, a support frame 12 is fixedly connected to the bottom of the lifting plate 7, and the push rod 11 and the transmission rod 15 both pass through the support frame 12.

Furthermore, the stirring motor 3, the delivery pump 5, and the control motor 8 mentioned above are all existing technologies and will not be elaborated upon in this solution.
[0038] The working principle of this utility model is as follows: In actual use, when concrete spraying is required, the processing tank 2 is moved to a suitable position via the base 1. Concrete is then poured into the feed hopper 4. A stirring rod is fixedly connected to the bottom of the output shaft of the mixing motor 3. By starting the mixing motor 3, the stirring rod is rotated to stir the concrete and prevent it from solidifying. At this time, the height of the nozzle 9 is adjusted according to the usage requirements. First, the control plate 10 is pushed to move laterally. When the control plate 10 moves, it will drive the push rod 11 to move laterally. The movement of the control plate 10 will compress the push spring 13.

When the transmission rod 15 moves, it will pull the limit plate 16 to move. When the limit plate 16 moves, it will disengage from the limit groove, thereby unlocking the lifting plate 7. At the same time, the movement of the limit plate 16 will drive the return plate 9 to move backward. The position plate 17 moves, and the movement of the reset plate 17 compresses the reset spring 18. At this time, the lifting plate 7 can be pushed to move, causing the nozzle 9 to move up and down. At this time, a limiting groove is opened at the corresponding position on the front side of the vertical rod 6. When the nozzle 9 moves to the appropriate position, by releasing the control plate 10, the pushing spring 13 will push the control plate 10 to move laterally to reset and pull the push rod 11 and the unlocking rod 14 to reset. At the same time, the reset spring 18 will push the reset plate 17, thereby driving the limiting plate 16 to move and reset, so that the limiting plate 16 and the limiting groove are engaged to fix the lifting plate 7, thereby fixing the nozzle 9 in the current position. At this time, the control motor 8 and the delivery pump 5 are started. The delivery pump 5 extracts the concrete in the processing tank 2 and sprays it out through the nozzle 9. The control motor 8 can easily drive the nozzle 9 to rotate and spray concrete. The mixing motor 3, the delivery pump 5 and the control motor 8 are all powered by an external power supply.
