[0001] The invention relates to a concrete feeding and spraying machine, in particular to a concrete feeding and spraying integrated machine. Background Art

[0002] In mining, tunneling shotcrete equipment is currently divided into two types:

[0003] 1. The rotor concrete spraying machine technology introduced into my country in the 1970s has defects such as short maintenance cycle, low spraying efficiency, poor sealing performance, and high dust near the machine;

[0004] 2. The push-chain concrete spraying machine technology with my country's own intellectual property rights developed in recent years has effectively made up for the shortcomings of the rotor concrete spraying machine technology.

[0005] Based on the technology of push-chain concrete spraying machine, the technology of concrete spraying machine (batching machine) was developed, which improves the quality of concrete spraying. With the development of technology and the needs of production, the volume of concrete spraying has gradually increased, the speed has gradually increased, and the size of the equipment has gradually increased, making the movement of the equipment more difficult; the shortage of labor, the increase in labor intensity and the space limitation of coal mine shafts are also facts in front of us.

[0006] In summary, the existing coal mine concrete spraying machines and their loaders cannot realize the functions of normal mechanical aggregate collection, mechanical loading, batching, concrete mixing and spraying operations while walking and moving.

[0007] At present, there is no all-in-one machine for concrete spraying which can simultaneously perform normal mechanical aggregate, mechanical loading, batching, concrete mixing and spraying functions while walking and moving. Summary of the invention

[0008] The present invention provides a concrete feeding and spraying integrated machine, which adopts an integrated design and integrates mechanical aggregate, mechanical feeding, batching, concrete mixing and spraying functions into one, solving the above-mentioned problems of concrete spraying machines and feeders for coal mines.

[0009] The technical solution adopted by the present invention to solve the above technical problems is described as follows:

[0016] The connecting frame connects the loading part and the chassis part into one body, and the supporting arm oil cylinder seat is fixed on the chassis.

[0017] A support wheel is arranged at the front position of the outer cylinder of the telescopic part of the loading part, and the support wheel and the connecting frame together form a shear beam structure.

[0018] The cement elevator is located at the side of the cement hopper and is tilted and fixed on the chassis. The cement elevator comprises a hopper and a conveyor.

[0019] The batching and conveying part comprises a hopper and a batching device.

[0020] The hoppers include a sand and gravel hopper, a cement hopper, and a quick-setting agent hopper.

[0046] The concrete feeding and spraying integrated machine of the present invention comprises a loading part 1, a batching and conveying part 2, a cement elevator 3, a chassis part 4, a horizontal screen 5, and a spraying part 6.

[0047] Figure 3 Schematic diagram of the structure of the loading unit of the present invention. Figure 3 As shown:

[0048] The loading part 1 is used for loading aggregates and sand and gravel; the cement elevator 3 contains spiral blades for lifting bulk cement to the batching and conveying part; the feeding part mixes the proportioned materials and then conveys them to the injection part; the injection part is a concrete sprayer.

[0049] The cement elevator 3 contains spiral blades for lifting bulk cement to the batching conveying section 2;

[0050] The loading part includes a bucket 7, a boom 10, a telescopic part, a supporting arm, and a connecting frame 13. The boom 10 is rigidly connected to the telescopic part through a boom seat 11 and is used for aggregate and sand and gravel loading. The telescopic part is composed of an outer cylinder, an inner cylinder and a telescopic cylinder. The boom includes a boom seat and a boom cylinder. The supporting arm includes a supporting arm cylinder 14 and a supporting arm cylinder seat 15. The connecting frame 13 connects the loading part 1 and the chassis part 4 as a whole, and the supporting arm cylinder seat 12 is fixed on the chassis 4. In addition, a support wheel 8 is provided below the front position of the outer cylinder of the telescopic part of the loading part 1. The support wheel 8 and the connecting frame 13 jointly form a shear beam structure. The telescopic part is composed of an outer cylinder, an inner cylinder and a telescopic cylinder.

[0051] The boom seat 11 is rigidly connected to the outer cylinder of the telescopic device. The connecting frame 13 connects the loading part 1 and the chassis part 4 as a whole. The supporting wheel 7 and the connecting frame 13 form a shear beam structure. The supporting arm cylinder seat 15 is fixed on the chassis part 4. When the supporting arm cylinder is contracted, the entire loading part is pulled up to facilitate the movement of the whole machine.

[0052] The structural principle and working process of the loading part 1 are as follows: a reversible bucket 7 is installed at the front end, and a movable arm 10 is connected to the loading part 1.

[0053] The left side of the boom 10 is connected to the telescopic part. After the boom 10 and the bucket 7 move to flip the bucket 7 to a certain position, the telescopic part extends forward to push the boom seat 11 to drive the boom 10 and the bucket 7 to move forward so that the bucket 7 is filled with sand and gravel, and the bucket is flipped so that the bucket opening faces upward; when the telescopic part retracts, the bucket is pulled back to a certain position, and the boom 10 performs a flipping movement to lift the bucket 7. At the same time, the bucket 7 performs a flipping movement in coordination with the movement of the boom 10 so that the bucket 7 opening always faces upward. When the bucket 7 reaches the unloading position, the boom 10 stops moving; the bucket 7 flips backward to unload the sand and gravel into the sand and gravel hopper of the batching and conveying part 2, completing the unloading action; the boom 10 and the bucket 7 are returned to their original positions to enter the next working cycle.

[0055] The structural principle and working process of the batching and conveying part 2 are as follows: the sand and gravel loaded into the sand and gravel hopper 16 by the loading part 1, the cement loaded into the cement hopper 17 by the cement elevator 3, and the accelerator in the accelerator hopper 19 are batched and output in a fixed proportion through the rotation of their corresponding spiral blades. The output materials enter the mixing tank of the mixing conveyor, and are mixed and conveyed forward under the rotation of the rotating blades of the mixing and conveying shaft. Finally, the mixed materials enter the horizontal screen 5 of the injection part through the discharge port.

[0056] like Figure 2 As shown in the overall structural diagram of the concrete feeding and spraying machine of the present invention, the spraying part 6 includes a spraying main machine; the spraying main machine can be any type of concrete spraying machine, including a rotor type or a push chain type.

The upper screen body and the lower screen body frame are both L-shaped steel, and the lower screen body is supported by a supporting wheel with a groove in the middle. One side of the screen body is connected to an eccentric wheel power device through a connecting rod; the eccentric wheel power device can be a hydraulic motor.

[0059] The chassis 4 of the concrete feeding and spraying integrated machine of the present invention is provided with a walking track.

[0060] Compared with the prior art, the present invention has the following beneficial effects:

The present invention has a cement elevator with a mechanical feeding function, and mechanical feeding reduces labor intensity to the maximum extent. The present invention installs a horizontal screen above the feed port of the sprayer. The mechanical forced screen body reciprocates to make the material shake, thereby achieving the purpose of screening the material.

[0062] Under the same workload and working conditions, the present invention uses fewer workers, has a faster speed and lower labor intensity. The loading part 1 has the functions of collecting and loading materials, replacing manual loading. The cement hoist 3 can also replace manual cement lifting.

[0063] While traveling, the machine can simultaneously carry out the operations of collecting, loading, batching, concrete mixing and spraying.
