Problems solved by technology

For the commercial concrete widely used in mines, it cannot be used due to the limitation of underground space and transportation in coal mines. For this reason, most coal mines currently use tank-mixing concrete production equipment, which has technical problems such as low efficiency and uneven mixing, and cannot be adapted. The need for continuous shotcrete on site

Embodiment Construction

[0016] The present invention will be further explained below in conjunction with the accompanying drawings.

[0017] A layered mixing concrete continuous feeding system, such as figure 1 , figure 2 As shown, it consists of a stirring system and a continuous feeding system. The mixing system includes several layers of vertically distributed layered mixing mechanisms. The layered mixing mechanism includes a long strip-shaped mixing tank fixed on the frame, and the frame is supported by legs arranged at the bottom. There is a stirring shaft in the stirring tank, a stirring blade is arranged on the stirring shaft, and a driving mechanism for driving the stirring shaft to rotate is arranged on the frame. The driving mechanism includes a power motor or an electric motor fixed on the frame, and gears for transmission, structures such as chains. The stirring shafts in the stirring tanks of each layer are composed of a first stirring shaft arranged horizontally in the middle, a sec...

Abstract

The invention discloses a layered stir concrete continuous feeding system which comprises a stir system and a continuous feeding system body. The stir system comprises a plurality of layers of layeredtype stirring mechanisms distributed vertically, each layered type stirring mechanism comprises a stir groove fixed to a rack, and the rack is supported through landing legs arranged at the bottom. Astir shaft is arranged in each stir groove and is provided with a stir blade, a water supply pipe is arranged at the top of each stir groove, a discharging opening is formed in the bottom of each stir groove and faces the corresponding lower-layer stir groove, and the discharging openings of the up and down adjacent stir grooves are located at the two opposite ends of the stir grooves. The rack is provided with a drive mechanism for driving the stir shafts to rotate, and the continuous feeding system body comprises a hopper and a feeding caterpillar band, the feeding caterpillar band is usedfor connecting an outlet of the hopper with the top-layer stirring grooves of the stir system. The layered stir concrete continuous feeding system is easy to operate, compact in structure, capable ofbeing suitable for most working conditions and capable of achieving continuous feeding of field concrete.

Description

technical field [0001] The patent of the present invention relates to the technical field of mining machinery and equipment, and more specifically, relates to a layered mixing concrete continuous feeding system. Background technique [0002] Coal mines in my country are mainly mined underground, and a large number of tunnels need to be excavated underground. Therefore, how to ensure the stability of the surrounding rock of the tunnel has always been the most concerned issue for engineers. At present, the most widely used roadway surrounding rock support theory is the New Austrian Method theory. Its basic principle is to use the bearing capacity of the surrounding rock itself, combined with anchor rods and shotcrete to support it and control its deformation and relaxation. Among them, shotcrete is the An important aspect of surrounding rock support based on the new Austrian method. [0003] At present, a shotcrete machine is often used to spray concrete onto the surface of t...
