Description

Sand yard intermittent type formula feeder

Technical Field

The utility model belongs to the technical field of the husky equipment of river sand washing, specifically be a sand yard intermittent type formula feeder.

Background

River sand is a mineral resource which is widely distributed and easy to mine, and the main equipment of a sand field mainly comprises screening, crushing, sand making, sand washing and conveying equipment, and the specification of concrete aggregate is achieved through crushing and screening. Except for sand, stones having a diameter of 0.7 cm to 5 cm are classified into 05 stones, 12 stones, 13 stones, and 24 stones in order according to the specification. The large stones with the size of more than 5 cm are circularly crushed and sieved to reach the size of less than 5 cm, and become required specifications, proper water is added in the sieving or crushing process for washing operation, and the large stones can be used as concrete aggregates after soil adhered on the large stones is removed.

River sand is mainly mined in riverways, wastelands or farmlands allowed by governments and then is transported to fixed places for processing, corresponding environmental protection procedures are needed, the sizes of mixture diameters are different, raw materials below 40 centimeters are pulled back to the sand field for processing in general sand fields, the mud content and the water content of mixture resources are changed according to the change of geographical positions, the raw materials in some places are clean, the raw materials in some places are particularly dirty, the water content in some places is large, and the water content in some places is not large.

The existing sand field washing operation mainly comprises three feeding modes, wherein one mode is to establish a concrete material platform, a storage bin is arranged on the material platform, a water spraying and flushing pipe is arranged on the wall of the storage bin, a lever type movable gate is arranged at the front opening of the storage bin, and raw materials are flushed into a vibrating screen or a cylindrical screen for washing operation in a manual material discharging mode; the second mode is that a storage bin is placed on the ground, raw materials are flushed into a raw material water pool in a manual discharging mode, and the raw materials are lifted into a vibrating screen or a cylindrical screen through a raw material bucket elevator to carry out washing operation; the third is to place a storage bin on the ground, but no spray pipe is arranged on the side wall of the storage bin, a ZG type vibration feeding machine is arranged at the lower discharge port of the storage bin, and the storage bin is uniformly fed onto a belt conveyor through the feeding machine and then is conveyed into a vibration sieve or a cylinder sieve through the belt conveyor to carry out washing operation. The former two kinds of feed modes are that the impulsive force through water sends the raw materials into washing equipment, and water is the power that the raw materials was carried, and consequently the center height of hopper is lower, and the lateral wall inclination is little, and the raw materials has washed once before not getting into washing equipment like this, has removed big mud, does benefit to subsequent washing operation more. The center height of the hopper is high in the third mode, the inclination of the side wall is large, the raw materials flow into the vibration feeding machine in a self-flowing mode, the water content of the raw materials is not more than 15%, and therefore the raw materials can be fed through the belt conveyor, otherwise, the raw materials skid on the belt and cannot be fed to a certain height.

In addition, the existing water material operation of the sand field is implemented by manually opening the movable gate, so that the labor intensity of workers is high, the working environment is severe, and the personnel is not safe. Secondly, the feeding is uneven, the operator must worry about the feeding all the time, otherwise, the subsequent equipment is not processed timely, the equipment is overloaded, particularly, a raw material bucket elevator, a vibrating screen and a cylindrical screen are pressed to be dead, the motor is burnt, and meanwhile, the motor can be restarted by manually using a shovel to draw out the raw material.

The method for manufacturing the movable gate by the existing equipment installer is different from person to person, the gate is simple to manufacture and convenient to use, and the lever principle is utilized to manually press down or lift up, but the defects exist, firstly, the steel plate hopper door is easy to clamp in an angle steel track in the lifting process, when raw materials are pressed on the hopper door, the hopper door is very laborious to lift up when the lever is pressed down, sometimes the hopper door is clamped and can not move, and the hopper door can be pried by a prying bar generally; secondly, the sandstone raw materials are easy to enter the steel angle rail, the hopper door is easy to be clamped, and the steel angle rail can move up and down freely only by beating with a hammer in work. The process that the operation workman operated movable gate all is these several actions basically, firstly open the gate to certain height, let the mixed water material freely even wash and select equipment, when the material mouth blocks up or runs into big stone, then raise the gate gently, the material mouth increases, let big stone or water material walk away under soaking of water, then put down the gate again, resume original height, otherwise the opening is too big, the raw materials in the storehouse collapses the mode like the mud-rock flow and washes in selecting equipment, cause equipment overload or stifle car, consequently for water material can wash and select equipment evenly, the operative employee only ceaselessly moves the gate from top to bottom, strive to keep the raw materials even flow, prevent that follow-up equipment from transshipping. Therefore, we propose a sand yard intermittent feeding device.

The working process after starting up is as follows:

firstly, after the second three-phase asynchronous motor 61, the screw rod lifter 62 raises the gate vertical moving part 1 to the height set by people through the travel switch 79, then the motor stops, and the opening degree of the gate can basically meet or be smaller than the working yield of subsequent production equipment.

Secondly, after the first three-phase asynchronous motor 51, the pulley 44 drives the cam 41 to rotate clockwise, the cam pushes the roller 34 to move up and down, then the rocker reciprocating component 3 drives the gate vertical moving component 1 to move up and down repeatedly through the sprocket 37 and the guide sprocket 24, the rising time, the falling time and the highest and lowest point dwell time of the gate 14 are all set on the outline dimension of the cam, the lower limit point of the gate movement is the height set by us, after the gate 14 falls to the height, the limit double nuts 66 at the lower part of the light bar 65 limit the gate 14 at the position, and therefore the gate 14 moves up and down repeatedly above the limited height.

When the hopper door 14 is limited to move above a certain height, and the hopper door 14 descends to the lowest point, a certain margin is generated on the length of the chain 23, the balancing weight 30 fixed on the chain 23 pulls the margin chain to one side as shown in the figure, so that the chain 23 is prevented from derailing or interfering with the hopper door 14, and the margin length is equal to the opening degree of the hopper door 14 in normal operation.

Therefore, when water is blocked or large stones exist instantaneously, the opening degree of the hopper door 14 can be increased to a high position, and when the rotating speed of the cam 41 is increased, the up-and-down movement times of the hopper door 14 are increased, so that the flow rate of the water is more uniform.

The shutdown sequence is as follows: firstly, after the screw rod elevator motor 61 rotates reversely, the light bar 65 is lowered to the lowest point specified by the limit switch, then the motor is stopped, when the movable gate moves downwards, the double nuts 66 at the tail part of the light bar 65 are not limited, and in one period of rotation of the cam 41, the movable gate can be lowered to the lowest point, and at the moment, the hopper door 14 is completely closed.
