Abstract

The utility model discloses a mining concrete sprayer with a mechanical conveying pump. The concrete sprayer comprises a base, wheels, a fan-shaped wheel, a gear rack, a gear, a hopper, S-shaped pipes, S-shaped pipe guiding shafts, mortar cylinder bodies, a water tank, a guiding cylinder, a motor and a gearbox, wherein the wheels are fixed below the base; the hopper, the water tank and the gearbox are fixedly arranged on the base; the motor is fixed on the gearbox; a crankshaft and two connecting rods are arranged in the gearbox; the connecting rods are connected with two pistons through the guiding cylinder; the pistons are arranged in two mortar cylinder bodies; the inlet end of each mortar cylinder body is arranged in the hopper; the S-shaped pipe is arranged at the inlet end of each mortar cylinder body; the S-shaped pipes are connected with the S-shaped pipe guiding shafts; and the S-shaped pipe guiding shafts are connected with a reversing control mechanism, and drive the S-shaped pipes to be butted with the inlet ends of the mortar cylinder bodies alternately. Therefore, dust cannot be generated during operation, and the body health of a worker and the ambient environment cannot be influenced; and the utility model has the characteristics that the concrete sprayer has low probability of damage, the rebound rate of concrete is lower, and the walling rate of concrete is high.

Description

Mine equipment formula delivery pump concrete sprayer

Technical field:

The utility model belongs to mine concrete sprayer technical field.

Background technology:

The concrete sprayer that uses is a rotator type at present, it is made up of hopper, special-shaped disk, panel, rotor block, clamp mechanism, gearbox, cyclone, last wind path, following wind path etc., its structural principle is that gearbox drives main shaft, main shaft drives rotor block, rotor block rotates continuous-feeding, rely on blast that concrete is blown out through cyclone, the concrete of ejection and tunnel and side slope wall bonding is solidified, reach tunnel and slope retaining reinforcement effect, prevent tunnel and slope deforming.Rotor spraying machine produces very big influence at the actual conditions dust that has following defective: a, blast to produce in service to operator and surrounding environment.The distance that b, rotor spraying machine are carried by blast is short, and rebound degree is bigger, and last wall rate is low, influences operating efficiency.The air compressor that c, rotor spraying machine will mate more than ten cubes could be worked, and has strengthened construction cost like this.The wear-out part of d, rotor spraying machine is more, as: rubber tile, material cup, steel liner plate, rubber spring, elbow, tapered sleeve etc., this has not only increased construction cost, also prolonged the time of construction, and damage easily at work, influence is produced, and increases worker's work repair density.

The utility model content:

The purpose of this utility model provides a kind of not fragile, less, the last high mine equipment formula delivery pump concrete sprayer of wall rate of concrete springback rate.

To achieve these goals, the utility model comprises: base, wheel, sectional wheel, the tooth bar, gear wheel, hopper, the S pipe, S manages the axis of guide, the ash sand jar body, water tank, guide cylinder, motor, gearbox, wheel is fixed on the bottom of base, hopper, water tank, gearbox is fixedly installed on the top of base, motor is fixed on the gearbox, in gearbox, also be provided with bent axle and two connecting rods, two connecting rods are connected with two pistons by guide cylinder, two pistons are positioned at two grey sand jar bodies, the arrival end of ash sand jar body is arranged in the hopper, arrival end at two grey sand jar bodies is provided with a S pipe, the S pipe is connected with the S pipe axis of guide, the S pipe axis of guide links to each other with commutation controlling mechanism, and S pipe axis of guide drive S pipe replaces commutation with two grey sand jar body arrival ends and docks.

Described commutation controlling mechanism is made up of gear wheel, tooth bar, sectional wheel, and the sectional wheel device is on gearbox, and sectional wheel drives S pipe axis of guide left and right sides alternatively swinging by tooth bar, gear wheel.

During work, motor drives bent axle by gearbox and rotates, the crank-driven connecting rod, connecting rod promotes piston, and two piston alternately front and back operations in two grey sand jar bodies are because the arrival end of grey sand jar body is arranged in the hopper, one sucks concrete, another then compresses concrete, and commutation controlling mechanism control S pipe makes the S pipe dock with the concrete grey sand jar body arrival end of compression.Like this, the concrete of compression extrudes through the S pipe, adds distinguished and admirable ejecting by flexible pipe again to shower nozzle, and concrete is ejected into tunnel and side slope surface, and concrete and tunnel and side slope wall bonding is solidified, and reaches tunnel and slope retaining reinforcement effect.The utility model can not produce dust, to workman's healthy nothing influence, surrounding environment is not had influence.Have characteristics such as not fragile, less, the last wall rate height of concrete springback rate.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a plan structure schematic internal view of the present utility model.

The specific embodiment:

As seen from Figure 1, Figure 2, the utility model comprises: base 1, wheel 2, sectional wheel 3, tooth bar 4, gear wheel 5, hopper 6, S pipe 7, the S pipe axis of guide 8, grey sand jar body 9, water tank 10, guide cylinder 11, motor 12, gearbox 13.Wheel 2 evenly is fixed on the both sides of the bottom of base 1, so as can be on underground orbit even running and park reliable.Hopper 6, water tank 10, gearbox 13 are fixedly installed on the top of base 1, and hopper is used to add concrete.Motor 12 is fixed on the gearbox 13, also is provided with bent axle 18 and two connecting rods 17 in gearbox 13, and motor drives bent axle by the transmission mechanism in the gearbox and rotates.Two connecting rods 17 are connected with two pistons 16 by guide cylinder 11, and two pistons 16 are positioned at 9, two pistons of two grey sand jar bodies and two grey sand jar body levels are arranged in juxtaposition, and piston external diameter contact with the sealing of dust and sand cylinder diameter and mates mutually.The arrival end of ash sand jar body 9 is arranged on bottom in the hopper 6, arrival end at two grey sand jar bodies is provided with a S pipe 7, the S pipe is connected with the S pipe axis of guide 8, and S manages the axis of guide 8 and links to each other with commutation controlling mechanism, and S pipe axis of guide drive S pipe alternately commutates with two grey sand jar body arrival ends and docks.Commutation controlling mechanism is made up of gear wheel 5, tooth bar 4, sectional wheel 3, and sectional wheel 3 devices are on gearbox, and sectional wheel 3 drives the S pipe axis of guide 8 left and right sides alternatively swingings by tooth bar 4, gear wheel 5.Wearing and tearing when docking in order to prevent that S manages and grey sand jar body arrival end alternately commutates are provided with drag ring 14 in the termination of S pipe, and the end face of grey sand jar body arrival end is provided with friction plate 15.The big I of specification of the present utility model is made series of products according to the quantity of sprayed mortar in the unit interval.
