Problems solved by technology

However, because the wet spraying process water is added manually, the randomness is large and the mixing is uneven, resulting in unstable quality of concrete, low initial strength of concrete, high rebound rate, and large dust in the working environment on site.

Embodiment 1

[0026] Such as Figure 1~2 As shown, a mining screw type quantitative water distribution conveying vehicle includes a car body 1, wheels 2 installed on the car body 1 and a water distribution and delivery device fixed on the car body 1, the water distribution and delivery Devices include:

[0027] The water distribution and delivery chamber includes a screw rod 3 inside, and the screw rod 3 is composed of a rod body 301 and a spiral blade 302 arranged along the outer surface of the rod body 301. The rod body 301 is a hollow tubular structure, and the middle part is formed through the In the water injection channel of the rod body 301, a helical groove is formed between every two adjacent helical teeth of the helical blade 302, and a plurality of through holes 303 for water supply and outflow are evenly arranged on the helical groove, and the water injection channel is connected to the water injection channel. The outside of the rod body 301 is connected, and the front end of ...

Embodiment 2

[0033] On the basis of Example 1, the bottom of the storage hopper 7 is provided with a material baffle 11 that can be extracted; the water distribution and delivery device also includes a storage hopper buffer plate 12, one end of which is fixed on the bottom of the water distribution and delivery chamber. The top and the other end are hinged with the bottom of the storage hopper 7, and the storage hopper 7 can be turned over in the direction of the buffer plate 12 of the storage hopper; a load-bearing mechanism is arranged on the side near the discharge port of the storage hopper 7 13. Contact with the storage hopper 7; the diameter of the through hole 303 is 1 mm, and the distance between every two adjacent through holes 303 is 10-15 mm.

[0034] The working method of the spiral quantitative water distribution vehicle of the present invention is as follows: inject water into the water tank, discharge the mixed dry material into the storage hopper 7, pull out the material baf...

Abstract

The invention discloses a mining spiral water-rationing transport vehicle. The mining spiral water-rationing transport vehicle comprises a vehicle body (1), vehicle wheels (2) installed on the vehicle body (1), a water-rationing and material-conveying device fixed on the vehicle body (1), a driving device (4), a water tank and a storage hopper (7), wherein the water-rationing and material-conveying device comprises a water-rationing and material-conveying chamber with a spiral rod (3) therein; the output end of the driving device (4) is connected with the back end of the spiral rod (3) through a water conveying pipeline (5); the input end of the driving device (4) is connected with a control unit; the water tank is connected with the water conveying pipeline (5); part of the water conveying pipeline (5) penetrates through the bottom of the water tank; a water injecting hole (6) is formed in the water conveying pipeline (5) inside the water tank; a discharge port at the bottom of the storage hopper (7) is connected with a feed port at the top of a water-rationing and stirring chamber. The mining spiral water-rationing transport vehicle can ration water mechanically and transport concrete.

Description

technical field [0001] The invention relates to a mine appliance, in particular to a mine-used spiral quantitative water distribution vehicle. Background technique [0002] At present, the wet spraying process used in shotcrete is to first put the pre-prepared cement, sand, stones and a certain amount of water into the sprayer, and then use high-pressure air to send it to the nozzle and mix it with the accelerator, and then use a certain amount of water to mix it with the accelerator. Spray at the sprayed surface of rock or concrete at a high speed. However, since the wet spraying process water is added by manual control, the randomness is large and the mixing is uneven, resulting in unstable quality of concrete, low initial strength of concrete, high rebound rate, and large dust in the working environment on site. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a screw-type quantitative water distribution vehic...
