[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0028] Please refer to Figures 1-6 , the present application provides a new technical solution: a concrete spraying machine for construction, including a concrete spraying machine for construction, which is characterized in that it includes a machine shell 1 for accommodating the main components of the spraying machine and protecting the internal components from external factors. The rotor spraying assembly 8 is fixedly installed on the machine shell 1 through a plurality of groups of fixators 9. The rotor spraying assembly 8 is used for spraying operations on concrete raw materials. A hopper 6 for storing the concrete raw materials to be sprayed is fixedly installed above the rotor spraying assembly 8. A partition board 19 is arranged between the hopper 6 and the rotor spraying assembly 8. A material dropping hole 14 is opened on the partition board 19 for communicating the hopper 6 and the rotor spraying assembly 8 and transporting the concrete raw materials from the hopper 6 to the inside of the rotor spraying assembly 8;
[0029] A main shaft 12 is arranged inside the rotor spraying assembly 8. The main shaft 12 penetrates through the partition board 19 into the hopper 6 and is sleeved with a blanking mechanism. The other end of the main shaft 12 is connected with a driving mechanism for driving the blanking mechanism to rotate inside the hopper 6 to accelerate the blanking of the concrete raw materials;
[0030] The blanking mechanism includes a top cone block 15 and a plurality of groups of stirring fan blades 13. The top cone block 15 is used for arch breaking, and the stirring fan blades 13 are used for stirring the concrete raw materials. A plurality of groups of through holes are opened on the stirring fan blades 13. The design of the through holes can improve the fluidity of the concrete raw materials, ensure that the raw materials can smoothly enter the rotor spraying assembly 8 through the material dropping hole 14, and accelerate the blanking speed.
[0031] In some embodiments, the driving mechanism includes at least one motor 18 and a speed reducer 17 connected to the motor 18. The output end of the speed reducer 17 is connected to a main shaft 12, and the main shaft 12 is used to drive the rotor spraying assembly 8 to rotate. Start the motor 18, drive the main shaft 12 to rotate through the speed reducer 17, and the rotor spraying assembly 8 realizes the spraying of concrete raw materials through the rotation of the main shaft 12.
[0032] In some embodiments, a vibrator 7 is fixedly installed on the outer side of the feeding hopper 6 to assist the flow of concrete raw materials. The frequency and amplitude of the vibrator 7 need to be adjusted appropriately to ensure the smooth flow of concrete raw materials without causing blockage. The installation of the vibrator 7 can effectively prevent the accumulation or arching of concrete raw materials in the feeding hopper 6 and ensure the smooth falling of the raw materials.
[0033] In some embodiments, a spraying hose 10 is connected to the output port of the rotor spraying assembly 8, and a spraying gun 11 is connected to the end of the spraying hose 10. The spraying hose 10 is used to convey the concrete raw materials from the rotor spraying assembly 8 to the spraying gun 11.
[0034] In some embodiments, walking wheels 2 are provided at the bottom of the machine shell 1 to drive the concrete spraying machine to move. The installation of the walking wheels 2 enables the concrete spraying machine to move conveniently at the construction site. A push handle 5 is fixedly installed at the rear side of the machine shell 1. The installation of the push handle 5 provides better control for the operator and facilitates them to push the spraying machine to different working locations. The design of the push handle 5 needs to consider ergonomics to reduce the burden on the operator.
[0035] In some embodiments, a control box 3 is fixedly installed at the rear side of the machine shell 1 to control the operation of the concrete spraying machine. The control box 3 is the operation center of the spraying machine, used to start and stop the spraying machine and control its working state. The control box 3 has easy-to-operate buttons and switches, as well as instruments or displays for showing the working state. The control box 3 can also include safety functions such as an emergency stop button to ensure the safety of the operator.
[0036] Working principle: During the use of a concrete spraying machine for construction, first ensure that the environmental conditions at the construction site are suitable for concrete spraying operations. The operator moves the concrete spraying machine to the predetermined spraying position by pushing the handle 5, then loads the concrete raw materials into the hopper 6, prepares for the spraying operation, starts the vibrator 7 to assist the flow of the concrete raw materials and prevents the raw materials from accumulating or agglomerating in the hopper 6, starts the motor 18, drives the main shaft 12 to rotate through the reducer 17, and provides power for the spraying operation. The rotation of the main shaft 12 drives the top cone block 15 and the mixing fan blades 13 in the feeding mechanism to work. The concrete raw materials are broken and mixed. The mixed concrete raw materials enter the rotor spraying assembly 8 through the drop hole 14 and are driven by the main shaft 12 to be sprayed to the construction surface. According to the construction requirements, the operator adjusts the spraying direction and distance of the spraying hose 10 and the spraying gun 11. Under the control of the control box 3, the sprayer starts the spraying operation and sprays the concrete raw materials evenly onto the construction surface. After the spraying operation of the predetermined area is completed, the motor 18 and the vibrator 7 are turned off to stop the sprayer. After the spraying operation is completed, the sprayer is cleaned and maintained as necessary to ensure the long-term and stable operation of the equipment.
