Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction equipment, in particular to a cement slurry truck. BACKGROUND

[0002] With the rapid construction of the country, the country attaches great importance to the road construction sector, and cement slurry is widely used. It can be used in construction, highway, bridge, water conservancy and other engineering, and can be used for the production of concrete products, and can also be used for the production of coatings, waterproof materials, etc. In addition, cement slurry can also be used in seismic engineering to improve the seismic performance of buildings. In traditional construction, cement slurry spreading is mainly completed by manpower, which has the defects of large manpower investment, poor spreading effect, and many safety hazards.

[0003] The cement slurry truck is a type of vehicle in road construction. Nowadays, there are semi-automatic cement slurry trucks on the market, which only have a water tank and a mixing tank. Manual addition of dry cement powder to the mixing bin is required, and then water is added to the mixing bin through the water tank for mixing before spraying. The cement slurry concentration ratio is very difficult to control, and strong experience is required to meet the practical needs, which not only wastes manpower but also has great limitations. The overall mixing uniformity cannot be reliably guaranteed, and the dry cement powder clumps in the mixing process cannot be fully broken and impacted and filtered, which easily causes the cement slurry nozzle to be blocked, resulting in uneven spraying, affecting construction quality, prolonging maintenance time, and reducing construction progress.

[0004] Moreover, the existing cement slurry truck can only spread mud on the ground and cannot spray mud on the roadside and vertical surface. In the process of work, if the mud is sprayed twice, the single cement slurry truck cannot use the rear spreading pipe to reinforce and spray twice. At the same time, for long-distance engineering repair work, the existing cement slurry truck cannot realize long-distance mud spraying for repair. At the same time, the existing cement slurry truck cannot perform dust suppression and cleaning operations on the road under construction or the road after construction. SUMMARY

[0056] When there is a river or pond in the construction range, the river or pond water pumping operation method is adopted; specifically, the preparation work before the operation is done, the mobile vehicle body 100 is as close as possible to the water intake point, the vehicle is parked and turned off after ensuring safety, the water suction hose is taken out, the four-way three-way ball valve inlet is connected, the other end of the water suction hose is placed in the water, and the water inlet is ensured to be below 300mm from the liquid surface. The four-way three-way ball valve handle is opened to the right first, and then the straight-through ball valve handle is opened to the left. Ensure that the water suction hose is not damaged or blocked, and the water pump is connected to the water suction hose. The working speed of the water pump can be adjusted by controlling the throttle, the water level indicator is observed in time, and the clutch pedal is depressed deeply when the maximum scale is reached, the power takeoff switch is closed, the clutch pedal is slowly released, the four-way three-way ball valve is closed to the left, the straight-through ball valve is closed to the right, the water suction hose is collected, and the water pumping operation is completed.

[0057] In this application, the sufficiency of the water source is ensured through different construction scenes, and the water source is sufficient for application of watering, flushing, and proportioning. Combined with the water tank 200 shown in Figure 2 and Figure 3 The dry powder cement tank 300 is used to carry dry powder cement, and the dry powder cement is placed in bags at the construction site and used as needed. The top of the dry powder cement tank 300 is equipped with a feeding tank cover 310, and the lower part of the dry powder cement tank 300 is a conical material guiding cavity; when the dry powder cement is poured into the dry powder cement tank 300, a plurality of bags of dry powder cement are poured into the dry powder cement tank 300 by opening the feeding tank cover 310, and the feeding tank cover 310 is closed to ensure its rainproof performance and dryness.

[0058] When the dry cement is accurately fed into the mixing tank group 400 in a quantitative manner, the auger conveying assembly rotates at the bottom of the material guiding cavity, and the conveying end of the auger conveying assembly is connected to the mixing tank group 400.

[0061] After the dry cement is conveyed by the auger 330 and introduced into the mixing tank group 400, the water tank 200 is connected to the mixing tank group 400 through a self-flow valve or a flow pump group. When the self-flow valve is used, an electromagnetic valve and a flow switch are arranged. In this way, the water source can be delivered to the mixing tank group 400 to mix with the dry cement in a specific ratio to form a cement slurry, thereby enabling all-around construction of road spreading operations, roadside and road surface spraying operations, roadside steep slope base reinforcement and hardening operations. During uniform rotation of the auger 330, the amount of dry cement conveyed is stable and controllable at the same time, thereby ensuring that the concentration of the mixed cement slurry is consistent during the operation, and the operation is scientific. Since the required concentration of the cement slurry is different for different road surfaces, the speed of the auger conveying assembly can be adjusted by a frequency converter, thereby controlling the overall required concentration of the cement slurry.
