Robot batch hopper

Abstract

The invention provides a robot batch hopper. The robot batch hopper comprises a quadrangular frustum pyramid shaped hopper, trapezoidal seesaws, breakers, arc-shaped scrapers, variable-frequency motors and a control module, wherein the trapezoidal seesaws are connected on the inner walls of the quadrangular frustum pyramid shaped hopper by supports; the breakers are connected on the quadrangular frustum pyramid shaped hopper by bearings; the arc-shaped scrapers are connected with the four corners of the quadrangular frustum pyramid shaped hopper by guide cylinders and are connected with micro axles at the lower end corners of the trapezoidal seesaws by first drive rods; the variable-frequency motors are connected on the outer walls of the quadrangular frustum pyramid shaped hopper by bolts, are connected with small axles on the seesaws by second drive rods and are meshed with gears at the axle ends of the breakers by sector gears; the variable-frequency motors are connected with the control module by conductors. The robot batch hopper has a novel structure, is smooth in feeding, is free from blockage, has stable properties and strong practicability and is firm and durable.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, and is particularly suitable for a quadrangular truss-shaped hopper in automatic control feeding equipment for concrete mixing. Background technique [0002] Among the automatic control feeding equipment currently used in concrete mixing plants, there are two types of square-shaped hoppers equipped with vibrators and screw propellers, both of which are used to make the medium sand in the square-shaped hopper automatically fall to the conveyor belt or fall into the mixer; The quadrangular truss-shaped hopper equipped with a vibrator and a screw propeller is suitable for medium sand with uniform sand, moisture content below 8%, and good fluidity, and for medium sand with a moisture content above 8%, or with broken small It is difficult to apply the medium sand of the frozen block, which often causes the medium sand in the square-shaped hopper to block and cannot fall, and do...

[0002] Among the automatic control feeding equipment currently used in concrete mixing plants, there are two types of square-shaped hoppers equipped with vibrators and screw propellers, both of which are used to make the medium sand in the square-shaped hopper automatically fall to the conveyor belt or fall into the mixer; The quadrangular truss-shaped hopper equipped with a vibrator and a screw propeller is suitable for medium sand with uniform sand, moisture content below 8%, and good fluidity, and for medium sand with a moisture content above 8%, or with broken small It is difficult to apply the medium sand of the frozen block, which often causes the medium sand in the square-shaped hopper to block and cannot fall, and does not meet the requirements of the mixed concrete specification. The medium sand of the broken small frozen block is easy to cause pouring Honeycombs appear in the concrete, which is also one of the causes of serious quality accidents in pouring concrete. When the loader pours the medium sand into the square-shaped hopper from top to bottom, the impact force is large, which increases the medium-sand in the square-shaped hopper. The bulk density, and the medium sand with high humidity has high bonding strength and strong support force. In addition, under the vibration of the vibrator, the medium sand gathers toward the lower mouth along the four directions of the slope wall of the square-shaped hopper. However, the distance between the conveyor belt and the lower mouth of the square-shaped hopper is small, and when the conveyor belt is not conveying, the medium sand is loaded more densely and cannot flow, especially the medium sand at the four corners of the square-shaped hopper is more difficult to slide down and loses fluidity. It cannot fall automatically; when the screw propeller pushes the medium sand in the quadrangular platform-shaped hopper, it forms a lower sky and upper canopy, and it cannot make the medium sand fall automatically, so that the automatic feeding equipment loses the function of automatic control of batching and feeding, and workers are required. Use a shovel to dig out the medium sand, and then put the medium sand into the square-shaped hopper one by one after it is unblocked. This wastes a lot of time, labor and machinery costs, and delays the construction period. Often cause frostbite quality accidents in concrete engineering and increase engineering costs
