Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing devices, in particular to a steel slag powder cement concrete mixing device. Background Art

[0002] The concrete mixing device is used for mixing cement concrete mixed with steel slag powder. The concrete mixing device is composed of a chassis, wheels, adjusting rods, pins, mixing hoppers, mixing blades, baffles, pulleys, motors, gears, and gear rings. When using the concrete to mix the cement concrete with steel slag powder, a tractor pulls the chassis to move to a designated location by means of the wheels, then adjusts the height by adjusting the rods, and then inserts the pins into the adjusting rods for positioning. The steel slag powder and cement concrete are put into the feeding port of the mixing hopper and water is added. The motor is started to make the gears rotate, so that the gear rings rotate, thereby driving the mixing hopper on the pulleys to rotate, and the mixing blades stir the steel slag powder and cement concrete. When discharging, the motor is reversed to discharge from one side of the baffle.

[0003] The inventor found in daily work that when the concrete mixing device is in use, since the gear rings and gear rings are exposed outside, the concrete is likely to splash onto the gear rings, causing the concrete to solidify on the gear rings. As a result, the mixing hopper will jump when rotating, which will affect the service life of the mixing hopper. To prevent the concrete from splashing onto the gear rings, protective covers are added on the upper surfaces of the gear rings and gears to avoid the concrete splashing onto the gear rings. However, since the protective covers wrap the gear rings and gears, it is necessary to remove the protective covers to inject lubricating oil, which may lead to more trouble in lubricating the gear rings and gears. Summary of the Utility Model

To prevent the concrete from splashing onto the gear rings, protective covers are added on the upper surfaces of the gear rings and gears to avoid the concrete splashing onto the gear rings. However, since the protective covers wrap the gear rings and gears, it is necessary to remove the protective covers to inject lubricating oil, which may lead to more trouble in lubricating the gear rings and gears, and to propose a steel slag powder cement concrete mixing device.

The convex part of the cam rotates to the operating rod and pushes the operating rod, so that the piston is extruded, and thus the lubricating oil is extruded, so that it is extruded from the oil pipe one to between the gear and the toothed ring, and further the effect of facilitating lubrication between the gear and the toothed ring can be achieved as much as possible.

[0007] Preferably, a spring is fixedly connected to the right end of the oil cylinder, and the other end of the spring is fixed to the operating rod.

The convex part of the cam rotates to the operating rod and pushes the operating rod, so that the piston is extruded, and thus the lubricating oil is extruded, and is extruded from the first oil pipe to between the gear and the gear ring, so as to achieve the effect of facilitating lubrication between the gear and the gear ring as much as possible. It solves the problem that since the gear ring and the gear are exposed outside, concrete is easily splashed onto the gear ring, causing the concrete to solidify on the gear ring, so that the mixing hopper will jump when rotating, which affects the service life of the mixing hopper. To avoid concrete splashing onto the gear ring, a protective cover is added on the upper surfaces of the gear ring and the gear, so as to avoid concrete splashing onto the gear ring. However, since the protective cover wraps the gear ring and the gear, the protective cover needs to be removed to inject lubricating oil, which may lead to the problem that it is more troublesome to lubricate the gear ring and the gear.

[0030] The following specifically describes the specific settings and functions of the lubrication assembly 2 and the water spraying assembly 3.

[0031] Referring to Figure 3 and Figure 4As shown in the figure, in this implementation: The lubrication assembly 2 includes a first oil pipe 21 fixedly connected to the arc surface of the protective cover 14. The inner wall of the chassis 1 is fixedly connected with an oil cylinder 22. The first oil pipe 21 is fixed to the oil cylinder 22. A piston 23 is arranged on the inner wall of the oil cylinder 22. The right end of the piston 23 is fixedly connected with an operating rod 24. The operating rod 24 penetrates through the oil cylinder 22. The output end of the motor 11 is fixedly connected with a cam 25. By setting the lubrication assembly 2, when lubrication is required between the gear 12 and the gear ring 13, the oil cylinder 22 is filled with lubricating oil. The motor 11 rotates, driving the gear 12 to rotate. Through the transmission of the gear ring 13, the mixing hopper 8 rotates, and at the same time, the cam 25 rotates. The protruding part of the cam 25 rotates to the operating rod 24 and pushes the operating rod 24, so that the piston 23 is extruded, and thus the lubricating oil is extruded, so that it is extruded from the first oil pipe 21 to between the gear 12 and the gear ring 13, and thus the lubrication between the gear 12 and the gear ring 13 can be conveniently achieved as much as possible. A spring 26 is fixedly connected to the right end of the oil cylinder 22. The other end of the spring 26 is fixed to the operating rod 24. By setting the spring 26, the operating rod 24 is reset.

The oil tank 28 is fixed to the chassis 1. When the operating rod 24 is reset, the piston 23 is reset, so that the oil in the oil tank 28 is pumped into the oil cylinder 22 through the second oil pipe 210. A one-way valve 29 is fixedly connected to the arc surface of the second oil pipe 210. By setting the one-way valve 29, the lubricating oil is prevented from flowing into the oil tank 28 when the piston 23 is extruded.

[0032] Referring to Figure 2 As shown in the figure, in this implementation: The water spraying assembly 3 includes a cavity ring 31 fixedly connected to the left end of the mixing hopper 8. The right end of the cavity ring 31 is fixedly connected with a water pipe 32. Water is filled into the cavity ring 31. When the mixer stirs steel slag powder, cement and concrete, the water is sprayed out from the water pipe 32, so as to spray water and mix it, thereby improving the mixing efficiency. A connecting ring 33 is rotatably connected to the arc surface of the cavity ring 31. The arc surface of the connecting ring 33 is fixedly connected with a water inlet pipe connected to an external water source.

Through the water inlet mechanism, the water flows into the cavity ring 31, so that the cavity ring 31 is filled with water. A first water hole 34 is opened on the inner arc surface of the connecting ring 33. A second water hole 35 is opened on the arc surface of the cavity ring 31. By setting the first water hole 34 and the second water hole 35, the water in the connecting ring 33 flows into the cavity ring 31. A sealing ring for sealing is arranged between the connecting ring 33 and the cavity ring 31.

[0033] Working principle:

[0034] When using cement concrete with steel slag powder, the tractor pulls the chassis 1 to move to the designated location by means of the wheels 5. Then, the height of the adjusting rod 4 is adjusted, and then the pin 6 is inserted into the adjusting rod 4 for limiting. The steel slag powder and cement concrete are put into the feeding port of the mixing hopper 8 and water is added. The motor 11 is started to make the gear 12 rotate, which makes the gear ring 13 rotate, thus driving the mixing hopper 8 on the pulley 7 to rotate, so that the mixing blades 10 mix the steel slag powder and cement concrete. When discharging, the motor 11 is reversed to discharge from one side of the baffle 9. When it is necessary to lubricate between the gear 12 and the gear ring 13, the oil cylinder 22 is filled with lubricating oil. The motor 11 rotates to drive the gear 12 to rotate. Through the transmission of the gear ring 13, the mixing hopper 8 rotates, and at the same time, the cam 25 rotates. The protruding part of the cam 25 rotates to the operating rod 24 and pushes the operating rod 24, so that the piston 23 is extruded, and thus the lubricating oil is extruded, so that it is extruded from the oil pipe 1 21 between the gear 12 and the gear ring 13, and thus the lubrication between the gear 12 and the gear ring 13 is as convenient as possible. By setting the spring 26, the operating rod 24 is reset. By setting the one-way valve 1 27, the backflow of the extruded lubricating oil is avoided. When the operating rod 24 is reset, the piston 23 is reset, and the oil in the fuel tank 28 is pumped into the oil cylinder 22 through the oil pipe 2 210. By setting the one-way valve 2 29, the lubricating oil is prevented from flowing into the fuel tank 28 when the piston 23 is extruded. The water source is connected to the water inlet pipe, and then the water enters the connecting ring 33. By setting the water hole 1 34 and the water hole 2 35, the water in the connecting ring 33 flows into the cavity ring 31. A sealing ring for sealing is arranged between the connecting ring 33 and the cavity ring 31, so that the cavity ring 31 is filled with water. When the cavity ring 31 is filled with water and the mixer mixes the steel slag powder, cement and concrete, the water is sprayed out from the water pipe 32. Since the connecting ring 33 and the cavity ring 31 rotate, the external connecting pipe is prevented from being wound due to rotation, so that the sprayed water is mixed with it, thus improving the mixing efficiency.
