Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of slope reinforcement engineering equipment, and more specifically to a dual-bucket alternating grout supply type integrated mixing and grouting machine. Background Technology
[0002] Slope reinforcement is an important civil engineering measure aimed at enhancing slope stability, preventing geological disasters such as landslides and collapses, and protecting the safety of residents, buildings, roads, and other structures below the slope.
[0003] Slope protection is a widely used method of slope protection. It involves using a slope drilling rig to drill holes in the prepared slope and insert steel anchor bolts, then injecting cement grout or cement mortar into the anchor bolt holes. Grouting is also a commonly used method for reinforcing cavities or cracks in the ground or slope.
[0004] Because the slope reinforcement area is large and the grout demand is also relatively large, it is best to move the machine flexibly along the slope. Therefore, in modern engineering, the mixer and grouting machine are combined into one unit, which can mix the grout anytime and anywhere and inject it flexibly. For example, a vertical mixing and grouting integrated machine disclosed in ZL201410677587.X has a secondary tank at the right end of the mixing tank. A vertical suction and discharge device is vertically installed inside the secondary tank. There are mixing blades inside the main tank. The secondary tank is connected to the main tank and the two are interconnected.
[0005] Raw material acquisition, mixing and pulping, and slurry injection are three important work steps that seem to need to be completed sequentially one after another. In fact, they can have a good margin of error. However, the above-mentioned patent obviously did not take this into account, which consumed a lot of waiting time, slowed down the progress of the project, and reduced work efficiency. Utility Model Content
[0006] The purpose of this utility model is to overcome the above-mentioned defects in the existing technology and provide a dual-bucket alternating slurry supply type integrated mixing and grouting machine, which aims to improve the fault tolerance rate of the three working links of raw material acquisition, mixing and slurry preparation and slurry injection, reduce the waiting time between them, speed up the project progress and improve work efficiency.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a dual-bucket alternating grouting and mixing integrated machine, comprising a frame, characterized in that a feeding hopper is provided at the top of the frame, a pair of spaced-apart feeding pipes are provided below the feeding hopper, each feeding pipe is provided with a pneumatic shut-off valve, a mixing tank is provided below each feeding pipe, a reducer is mounted at the upper opening of each mixing tank, a hydraulic motor is connected to the input shaft of each reducer, an agitator is axially connected to the output shaft of each reducer, a discharge pipe is provided below each mixing tank, a pneumatic butterfly valve is provided on each discharge pipe, the two discharge pipes are connected to a conveying pipe, and the conveying pipe is connected to a grouting pump.
[0008] This utility model features a dual-mixing tank design, employing pneumatic shut-off valves and pneumatic butterfly valves to rationally control the opening and closing of the feeding and discharging processes. One mixing tank is used for filling and pulping, while the other can be used for grouting. This design aims to improve the fault tolerance of the three work stages of raw material acquisition, mixing and pulping, and grout injection, reduce waiting time between them, accelerate project progress, and improve work efficiency.
[0009] Grouting pump: The discharge speed is adjustable, and it can inject cement grout and cement mortar. When combined with high-pressure air, it can be used for slope vegetation protection, such as spraying mud mixed with plant seeds (including loess or nutrient soil).
[0010] Preferably, the stirrer includes a stirring shaft and stirring blades, with the stirring blades disposed on the free end of the stirring shaft.
[0011] The mixing blades can be turbine-type, occupying only the free end of the mixing shaft, or ribbon-type, occupying the entire mixing shaft, depending on whether it is cement slurry, mortar, or vegetation slurry.
[0012] Preferably, an air pump is provided on the frame, and the two pneumatic shut-off valves and the two pneumatic butterfly valves are respectively connected to the air pump.
[0013] The air pump provides power to pneumatic shut-off valves and pneumatic butterfly valves. It is packaged with the equipment and is flexible and convenient to move.
[0014] Preferably, a lifting ring is provided at each of the four top corners of the frame.
[0015] Lifting rings are used to install and stabilize the frame, for example, by hoisting it onto a crane and lifting it to a sufficient height, similar to a shifting grouting machine used to inject grout into very high rock walls.
[0016] Preferably, a mounting ring is provided at each of the four bottom corners of the frame.
[0017] Mounting rings are used to install and stabilize the frame. For example, they can be mounted on a hydraulic tracked machine for easy movement, essentially acting as a mobile grouting machine. This meets the characteristics of long slopes and allows for flexible relocation, enabling grouting and injection anytime, anywhere.
[0018] Preferably, an escalator is provided on the frame.
[0019] Escalators help construction workers climb to check the material level in the feed hopper, facilitating timely replenishment. Furthermore, multiple escalators can be installed, reinforcing the overall frame and providing stable support for the entire equipment.
[0020] Beneficial effects: This utility model is designed with a double mixing tank and uses a pneumatic shut-off valve and a pneumatic butterfly valve to reasonably control the opening and closing of the feeding and discharging. One mixing tank is used for filling and pulping, while the other mixing tank can be used for grouting. The aim is to improve the fault tolerance of the three working links of raw material acquisition, mixing and pulping and grouting injection, reduce the waiting time between them, speed up the project progress and improve work efficiency.

Detailed Implementation
[0024] To make the technical means, creative features and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.
[0025] Example: Figure 1 and Figure 2 As shown, a dual-bucket alternating grout supply type integrated mixing and grouting machine includes a frame 1, an installation ring 14 is respectively provided at the four bottom corners of the frame, a hoisting ring 15 is respectively provided at the four top corners of the frame 1, and a ladder 16 is provided on the frame.
[0026] A feeding hopper 2 is provided at the top of the frame 1. A pair of feed pipes 3 are arranged at intervals below the feeding hopper 2. A pneumatic shut-off valve 4 is provided on each feed pipe 3. A mixing tank 5 is provided below each feed pipe 3. A reducer 6 is mounted at the upper opening of each mixing tank 5. A hydraulic motor 7 is connected to the input shaft of each reducer 6. An agitator 8 is shaft-connected to the output shaft of each reducer 6. The agitator 8 includes a mixing shaft and mixing blades. The mixing blades are located on the free end of the mixing shaft.
[0027] Each mixing tank 5 is equipped with a discharge pipe 9 at its bottom, and each discharge pipe 9 is equipped with a pneumatic butterfly valve 10. The two discharge pipes 9 are connected to a conveying pipe 11, and the conveying pipe 11 is connected to a grouting pump 12 (available for immediate purchase). The grouting pump uses compressed oil or compressed air as a power source. It utilizes the large working area ratio between the oil cylinder or air cylinder and the grouting cylinder to generate a high injection pressure in the cylinder with a small pressure.
[0028] An air pump 13 is installed on the frame 1, and two pneumatic shut-off valves 4 and two pneumatic butterfly valves 10 are respectively connected to the air pump 13.
[0029] Working process: Upon initial startup, fill the feed hopper with material and simultaneously open the start-up shut-off valve to fill the two mixing tanks. Then, start the hydraulic motor, increasing torque through the reducer to drive the mixing shaft, thereby achieving slurry preparation. Depending on the actual situation—whether it's a shotcrete slope or a grouting cliff—use a crane or a hydraulic crawler for transportation. After delivery to the designated location, open the pneumatic butterfly valve of one mixing tank to inject grout using the grouting pump. When the slurry in that mixing tank is depleted, close its pneumatic butterfly valve and open its start-up shut-off valve to continue filling and mixing the slurry. Simultaneously, the grouting pump does not need to be shut down; the pneumatic butterfly valve of the other mixing tank can be opened to supply material, and this process is repeated.
