Description

Technical Field

[0001] This utility model relates to the field of concrete spraying machine technology, specifically a multi-functional concrete spraying machine with a replaceable rotor. Background Technology

[0002] A concrete spraying machine is a mechanical device used in construction, bridge, tunnel, underground engineering and other projects to spray concrete or other materials. From the analysis of the structure and working principle of the concrete spraying machine, the different specifications of the concrete spraying machine are mainly distinguished by the spraying volume. The different spraying volumes are determined by the size of the rotor body, while the frame, walking system, power system and other auxiliary parts of the equipment are almost shared.

[0003] However, existing devices have the following problems in actual use:

[0004] 1. Existing concrete spraying equipment has a single configuration and fixed working capacity, which cannot meet the spraying needs of customers under different conditions. For example, when the construction site needs to carry out short-distance spraying with a large amount of spraying, if there is only one machine with a small spraying capacity, the spraying efficiency will be too low, wasting manpower and delaying the project progress. On the other hand, when the construction site needs to carry out long-distance spraying with a small amount of spraying, if there is only one machine with a large spraying capacity, forced construction will cause problems such as pipe blockage and high rebound rate, resulting in poor project quality and significant waste. For some small-scale projects, if new equipment is purchased to ensure project quality, the budget will be increased, which will also increase the construction cost of the entire project and cause the equipment to be idle and wasted.

[0005] 2. Slow switching of working modes: When it is necessary to switch from a short-distance high-volume shotcrete mode to a long-distance low-volume shotcrete mode, or vice versa, it is necessary to replace another piece of equipment, reconnect the equipment, reconnect the power supply, and rearrange the shotcrete pipes and water pipes, which wastes a lot of time. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To overcome the aforementioned shortcomings of the prior art, this utility model provides a multi-functional concrete spraying machine with a replaceable rotor, solving the problems in the prior art:

[0008] 1. Existing concrete spraying equipment has a single configuration and fixed working capacity, which cannot meet the spraying needs of customers under different conditions. For example, when the construction site needs to carry out short-distance spraying with a large amount of spraying, if there is only one machine with a small spraying capacity, the spraying efficiency will be too low, wasting manpower and delaying the project progress. On the other hand, when the construction site needs to carry out long-distance spraying with a small amount of spraying, if there is only one machine with a large spraying capacity, forced construction will cause problems such as pipe blockage and high rebound rate, resulting in poor project quality and significant waste. For some small-scale projects, if new equipment is purchased to ensure project quality, the budget will be increased, which will also increase the construction cost of the entire project and cause the equipment to be idle and wasted.

[0009] 2. Slow switching of working modes: When it is necessary to switch from a short-distance high-volume shotcrete mode to a long-distance low-volume shotcrete mode, or vice versa, it is necessary to replace another piece of equipment, reconnect the equipment, reconnect the power supply, and rearrange the shotcrete pipes and water pipes, which wastes a lot of time.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-functional concrete spraying machine with replaceable rotor, including a frame for supporting the entire spraying machine, a walking mechanism movably installed at the bottom of the frame for facilitating device movement, a power cabinet at the top of the frame for providing power to the device, a first rotor movably installed at the top of the frame for controlling the spraying volume, two limiting seats at the top of the frame for facilitating support of the hopper seat, multiple clamping structures at the top of the frame for controlling the lifting and lowering of the hopper seat, a hopper seat for feeding material movably installed at the top of the limiting seats, and a cyclone separator for spraying at one end of the frame.

[0012] Optionally, one end of the frame is provided with a support column, and the top of the support column is provided with a handle for easy hand gripping.

[0013] Optionally, a cabinet door for closing is movably installed on one side of the power cabinet, and a drive structure for providing power is provided inside the power cabinet.

[0014] Optionally, the first rotor body can be replaced by two second rotor bodies and a third rotor body of different sizes, wherein the second rotor body and the third rotor body are a small rotor body and a large rotor body, respectively, and the height of the small rotor body is lower than the height of the large rotor body.

[0015] Optionally, one end of the clamping mechanism is movably mounted with an adjustable telescopic tube, and the bottom of the telescopic tube is fixedly mounted with a support for easy installation.

[0016] Optionally, a feed hopper for feeding is fixedly installed on the top of the hopper seat, and a mounting block for connecting with the limiting seat is provided on one side of the hopper seat.

[0017] (III) Beneficial Effects

[0018] This utility model provides a multi-functional concrete spraying machine with a replaceable rotor, which has the following advantages:

[0019] 1. This interchangeable rotor multi-functional concrete spraying machine integrates the machine frame, walking mechanism, power cabinet, and other auxiliary components in a rational layout. Utilizing adjustable height limit seats and adjustable clamping mechanisms, it allows for the installation of rotors of varying heights to provide different spraying volumes, thus meeting diverse user needs. It enables flexible switching between large spraying volumes at close range and small spraying volumes at long range. Therefore, purchasing a single unit allows for multi-functional conversion, satisfying different construction requirements without the need to purchase different specifications of similar equipment, significantly reducing equipment procurement costs.

[0020] 2. This multi-functional concrete spraying machine with replaceable rotor body is easy to operate due to the installation relationship between the structures. Replacing the key component rotor body requires fewer steps and is faster because the main body of the equipment is stationary. Only the clamping mechanism and hopper seat need to be removed, and the required rotor body needs to be installed. The clamping mechanism and front and rear limit seats are designed to be height adjustable and do not need to be replaced. Then, the hopper seat and clamping mechanism are reset, and the pressure of the clamping mechanism is adjusted appropriately, and it can work normally. Attached Figure Description
