It is suitable for various construction projects, from large-scale projects such as bridges, tunnels, and subways to smaller projects like residential buildings and renovations. The concrete spraying machine can evenly spray concrete onto the surface of a building, forming a dense and robust protective layer, thereby improving the building's compressive strength, impact resistance, and corrosion resistance, and extending its service life. Its highly efficient spraying capability can significantly improve construction efficiency, shorten the construction period, and reduce labor costs.

[0003] However, existing concrete spraying machine hoppers often lack screen plates that can be quickly installed and disassembled. Existing concrete spraying machine hoppers are generally installed and fixed with fixing bolts, which is time-consuming and labor-intensive to install, and it is inconvenient to disassemble the hopper for cleaning and use. Therefore, there is an urgent need for a concrete spraying machine to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a concrete spraying machine to solve the problem mentioned in the background art that the hopper of the existing concrete spraying machine often does not have a screen plate that can be quickly installed and disassembled. The hopper of the existing concrete spraying machine is generally installed and fixed by fixing bolts, which is time-consuming and laborious to install and inconvenient to disassemble the hopper for cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete shotcrete machine, comprising a shotcrete machine body, a feed hopper, a fixing structure, and a screen plate. The feed hopper is provided at the top of the shotcrete machine body. The fixing structure includes a fixing seat and a fixing column. The fixing seat is fixedly connected to the inner wall of the shotcrete machine body. Two insert rods are fixedly connected to the top of the fixing seat. The two insert rods are slidably connected to a limiting seat. The fixing column is fixedly connected to the outer wall of the shotcrete machine body. The fixing column is threadedly connected to a threaded rod. Insert rod two is fixedly connected to the side of the threaded rod near the middle. Insert rod two is inserted into the limiting seat. The fixing seat and the limiting seat are engaged with the screen plate. Two rubber sleeves are fixedly connected to the top of the screen plate.

[0006] Preferably, four fixing structures are provided: four fixing seats are equidistantly distributed on the inner wall of the shotcrete machine body, and four fixing columns are equidistantly distributed on the outer wall of the shotcrete machine body.

[0007] Preferably, a handle is fixedly connected to the side of the threaded rod away from the center. The handle is a hexagonal handle with an anti-slip coating on its surface.

[0008] Preferably, the second insertion rod is a flat-topped conical insertion rod, and the limiting seat has a conical insertion hole corresponding to the second insertion rod.

[0009] Preferably, rubber pads are fixedly connected to both the upper and lower sides of the screen plate. The rubber pads are circular and are fixedly connected to the frame of the screen plate.

[0010] Preferably, the rubber pad at the bottom abuts against the fixing seat, and the rubber pad at the top abuts against the limiting seat.

[0013] 1. This concrete spraying machine is equipped with a fixed structure. When the screen plate needs to be installed, the screen plate is placed on the fixed seat, so that the fixed seat is engaged with the bottom edge of the screen plate. The limiting seat is inserted into the first insert rod, so that the limiting seat is engaged with the top edge of the screen plate. The handle is rotated, so that the handle drives the threaded rod to rotate, so that the threaded rod drives the second insert rod to move towards the center, so that the second insert rod is inserted into the insertion hole of the limiting seat, thereby fixing the position of the limiting seat. The screen plate is fixed in position by the fixed seat and the limiting seat. When the screen plate needs to be removed, the handle is reversed, the limiting seat is pulled out, and then the handle is pulled up to remove the screen plate. The fixed structure facilitates the quick installation and removal of the screen plate, improves the installation and removal efficiency of the screen plate, and is convenient and quick to operate and easy to use.

[0014] 2. This concrete spraying machine is equipped with rubber pads. The rubber pads prevent the frame of the screen plate from directly contacting the fixed seat and the limiting seat. The rubber pads can cushion the screen plate, increase the friction between the frame of the screen plate and the fixed seat and the limiting seat, improve the stability during clamping, and the elasticity of the rubber pads can prevent the fixed seat and the limiting seat from squeezing the screen plate and causing damage to the frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides an embodiment of a concrete spraying machine, including a spraying machine body 1, a feed hopper 2, a fixing structure 3, and a screen plate 4. The feed hopper 2 is provided at the top of the spraying machine body 1. The fixing structure 3 includes a fixing seat 31 and a fixing column 34. The fixing seat 31 is fixedly connected to the inner wall of the spraying machine body 1. Two insert rods 32 are fixedly connected to the top of the fixing seat 31. The two insert rods 32 are slidably connected to a limiting seat 33. The fixing column 34 is fixedly connected to the outer wall of the spraying machine body 1. The fixing column 34 is threadedly connected to a threaded rod 35. Insert rod 36 is fixedly connected to the side of the threaded rod 35 near the middle. Insert rod 36 is inserted into the limiting seat 33. The fixing seat 31 and the limiting seat 33 are engaged with the screen plate 4. Two rubber sleeves 43 are fixedly connected to the top of the screen plate 4. The fixing structure 3 facilitates the quick installation and disassembly of the screen plate 4, improving the installation and disassembly efficiency of the screen plate 4 and making the operation convenient and quick.

[0023] Furthermore, the fixing structure 3 is provided with four fixed seats 31 equidistantly distributed on the inner wall of the shotcrete machine body 1 and four fixed columns 34 equidistantly distributed on the outer wall of the shotcrete machine body 1. The screen plate 4 is placed on the fixed seat 31 so that the fixed seat 31 is engaged with the bottom edge of the screen plate 4. The limiting seat 33 is inserted into the insertion rod 32 so that the limiting seat 33 is engaged with the top edge of the screen plate 4.

[0024] Furthermore, a handle 37 is fixedly connected to the side of the threaded rod 35 away from the middle. The handle 37 is a hexagonal handle with an anti-slip coating on its surface. The anti-slip coating prevents slippage when rotating the handle 37, and the hexagonal handle is easier to hold.

[0025] Furthermore, the second insertion rod 36 is a flat-topped conical insertion rod, and the limiting seat 33 has a conical insertion hole corresponding to the second insertion rod 36. The threaded rod 35 drives the second insertion rod 36 to move towards the middle, so that the second insertion rod 36 is inserted into the insertion hole of the limiting seat 33, thereby fixing the position of the limiting seat 33.

[0026] Furthermore, rubber pads 41 are fixedly connected to both the upper and lower sides of the screen plate 4. The rubber pads 41 are circular and are fixedly connected to the frame of the screen plate 4. The rubber pads 41 can buffer the screen plate 4 and increase the friction between the frame of the screen plate 4 and the fixed seat 31 and the limiting seat 33, thereby improving the stability during clamping.

[0027] Furthermore, the bottom rubber pad 41 abuts against the fixed seat 31, and the top rubber pad 41 abuts against the limiting seat 33. The rubber pad 41 can prevent the frame of the screen plate 4 from directly contacting the fixed seat 31 and the limiting seat 33. The elasticity of the rubber pad 41 can prevent the fixed seat 31 and the limiting seat 33 from squeezing the screen plate 4, which would cause damage to the frame.

[0028] Furthermore, the rubber sleeve 43 is made of heat-insulating silicone material and has an uneven texture on its surface. The rubber sleeve 43 can increase the friction between the handle 42 and the palm, and can also play a role in heat insulation, thereby improving the comfort of holding.

[0029] Working principle: When installing the screen plate 4, place it on the fixing base 31, so that the fixing base 31 engages with the bottom edge of the screen plate 4. Insert the limiting seat 33 into the insertion rod 32, so that the limiting seat 33 engages with the top edge of the screen plate 4. Rotate the handle 37, so that the handle 37 drives the threaded rod 35 to rotate, so that the threaded rod 35 drives the insertion rod 36 to move towards the center, so that the insertion rod 36 is inserted into the insertion hole of the limiting seat 33, thereby fixing the position of the limiting seat 33. The screen plate 4 is fixed in position by the fixing base 31 and the limiting seat 33. When it is necessary to remove the screen plate 4, reverse the handle 37 and pull out the limiting seat 33. Pull the handle 42 upwards from the base 33 to remove the screen plate 4. The fixing structure 3 facilitates quick installation and removal of the screen plate 4, improving the efficiency of installation and removal. The operation is convenient and quick, and easy to use. The rubber pad 41 prevents the frame of the screen plate 4 from directly contacting the fixing base 31 and the limiting base 33. The rubber pad 41 can buffer the screen plate 4 and increase the friction between the frame of the screen plate 4 and the fixing base 31 and the limiting base 33, improving the stability during clamping. The elasticity of the rubber pad 41 can also prevent the fixing base 31 and the limiting base 33 from squeezing the screen plate 4, which would cause damage to the frame.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
