Description

Method for feeding and discharging granular materials into and out of pit-free horizontal warehouse

Technical Field

The invention relates to a warehouse discharging machine for a horizontal warehouse, in particular to a warehouse feeding and discharging method for particle materials of the horizontal warehouse without a pit, and belongs to the technical field of warehouse discharging machines.

Background

The horizontal warehouse is widely used for storing bulk materials (such as soybeans, rapeseeds, bean pulp, rapeseed meal and the like), and has the advantages of flexible storage, low civil engineering investment cost and the like. The storage yard is rectangular, the width of the storage yard is relatively wide and often reaches 30-40 meters, the material pile is also relatively high usually, and the depth sometimes reaches two hundred meters or more. The most common mode of delivering from godown of tradition is that the workman drives the forklift and loads the material to pit conveying equipment and truck carriage in, has very big potential safety hazard, has very big demand to the automatic delivery from godown in square storehouse. At present, delivery equipment is also provided, but the investment cost is high, the equipment problems are more, the faults are high, and the delivery equipment is basically matched with a loading forklift to work. The track and the blanking are sealed, the tunnel design is too complicated, and the automatic discharging in the true sense cannot be realized. The currently common delivery methods are listed as follows:

firstly, discharging of a loading forklift: push away the material to middle feed opening, the feed opening is equipped with a plurality of gates on ground along length direction, and during the ejection of compact, the gate is opened one by one, loads the forklift and pushes away the material to the feed opening unloading. The defects are as follows: the manual operation of the forklift is extremely poor, the materials are polluted by a loading forklift, and the danger of dust explosion exists; the discharge gate sets up a plurality of shutter mechanisms, and the trouble is many. During discharging, the bin door is opened, the water loss is fast, the total weight of materials is obviously reduced during large amount, and the economic loss of customers is caused.

Secondly, hanging a discharging machine at the top of the bin: the feed opening length direction is equipped with a plurality of gates subaerial, during the ejection of compact, opens one by one, and the hanging machine hangs the side from last to down with the material. The hanging machine is hung above and needs to work along the length direction and the depth direction, so that the stability is poor and the discharging speed is slow; and overhead maintenance is difficult; the discharging is shaken to cause the falling risk, and the old bin can not be transformed.

Thirdly, a ground auger grain delivery machine: the left side, the middle or the right side of the horizontal warehouse is provided with a feed opening, a plurality of gates are arranged on the ground along the length direction of the feed opening, and the gates are opened one by one when the ground auger walks to discharge. The defects are as follows: materials cannot be arranged on the motor side and the driven side, and the storage capacity is reduced by more than 1/3; the discharging pit equipment is difficult to maintain; the gate of the feed opening is too many, and the maintenance and fault points are too many; the teeth are easy to climb or derail when the vehicle runs along the track; the driven side is far left against the wall; the auger has more hanging and poor strength, and materials cannot be discharged after being slightly hardened; once the drive is buried by landslide material, can't start, current one-storey house storehouse also can't reform transform.

Fourthly, a ground scraper grain delivery machine: a feed opening is usually arranged in the middle of the horizontal warehouse, a plurality of gates are arranged on the ground along the length direction of the feed opening, and the gates are opened one by one when the ground scraper is used for horizontally moving and discharging; motor drive arranges the middle part in, and the pit top sets up similar umbelliform fender material mechanism, opens the feed opening through hydraulic pressure or pneumatic door, and is with high costs, and the fault point is too many, and current bungalow storehouse also can't be reformed transform. The discharging pit equipment is difficult to maintain; the number of gates of the feed opening is large, and the number of maintenance and fault points is too large; the chain wheel and the chain drive the walking to be easy to clamp and disengage the shell; the plane friction force is large and is easy to block; the returned material on the scraper chain cannot be processed.

In conclusion, the discharging of the existing grain discharging machine has the following defects:

1. pits are dug, and equipment under the pits is difficult to maintain and high in cost; the ground of the old horizontal warehouse is composed of a surface layer, a moisture-proof layer, a leveling layer, a structural layer, a cushion layer and other structural layers, the requirement is very high, the original ground is damaged, a pit is additionally arranged along the axis, the whole structure and the stability of the square warehouse are greatly influenced, and the improvement on the technology and the investment can not be carried out;

2. a material blocking gate or a material blocking door is required to be arranged at a feed opening of the pit, and the longer the horizontal warehouse is, the more the doors are, the more the control door opening pieces are, the damage is easy to occur, and the maintenance is frequent; when the trolley lines and the air pipes are laid in a pit, faults occur frequently due to excessive dust, sparks are easily caused due to poor contact of the trolley lines, and the risk of dust explosion is increased;

3. the track is buried in the material and filled with the material, so that tooth climbing or derailment is easy to cause, and recovery is difficult; the ground of the horizontal warehouse is formed by pouring concrete, and certain error exists in levelness due to huge area; the track is a steel structural member and cannot synchronously fluctuate along the ground due to high points on the front side and the rear side, and when the grain delivery machine normally travels along the track, the gap between the transverse discharging auger and the ground is easily too large, so that excessive residual materials are caused;

4. the bin rail on the suspended ceiling is hung on the beam, so that the bin rail is not easy to maintain and has the risk of falling;

5. horizontal ejection of compact auger needs install the main drive subassembly in one end, and driven subassembly is installed to the other end, and the main drive subassembly drive horizontal ejection of compact auger is rotatory, and main drive subassembly and driven subassembly all need occupy certain space, builds the track roof beam on the both sides wall limit in bungalow storehouse usually, and the top level of track roof beam, lower part fretwork. The walking device is supported at the top of the track beam to drive the grain delivery machine to move forward or backward, the auger driving assembly is arranged below the track beam, a drooping apron board is arranged at the edge of the inner side of the track beam to prevent materials from entering a space where the driving assembly is located, and the heights of two sides of the material pile cannot be higher than the top of the track beam. The construction of the track beam in the new horizontal warehouse greatly increases the investment, prolongs the construction period, reduces the effective width of the horizontal warehouse, limits the height of a stockpile, reduces the storage space by more than one third, and often cannot transform the old horizontal warehouse.

6. After materials such as grain get into the horizontal warehouse and store, the cycle of depositing is three years at least usually, and traditionally every horizontal warehouse independently forms a complete set grain delivery machine, after each time of delivery, waits to store up full material again, continues to wait for the ejection of compact more than three years, and grain delivery machine's rate of utilization is low excessively, idle time overlength, and investment cost is too high, maintains that the maintenance is not enough then more easily breaks down.

Detailed Description

In the following description of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not mean that the apparatus must have a specific orientation.

The invention relates to a method for feeding and discharging granular materials into and out of a pit-free horizontal warehouse, which respectively comprises the following steps:

feeding materials into a bin: send into scraper blade cloth machine 48 with the storehouse material in, scraper blade cloth machine 48 locates the below of bungalow storehouse spire and extends along bungalow storehouse's length direction, evenly is equipped with a plurality of cloth mouths 48a on scraper blade cloth machine 48's the bottom plate, opens the cloth gate of cloth mouth 48a below, and the material is freely scattered and is piled up the material awl on ground, and when the material awl top was close the cloth gate, this cloth gate was closed.

The scraper distributing machine 48 is connected by a plurality of end-to-end force extension, the feeding end of the downstream scraper distributing machine is positioned below the discharging end of the upstream scraper distributing machine, and a high material level sensor lower than the lower port of each distributing gate is arranged below one side of each distributing gate; the distribution gates in the safe distance ranges of the front side and the rear side of the grain delivery machine are always closed. Namely, the material piles on the front side and the rear side of the grain delivery machine naturally collapse, and the grain delivery machine cannot be buried. For example, the natural angle of the cone of a certain material is 30 degrees, and then the safe distance between the cone and the grain delivery machine is reserved on the basis of the natural angle. The horizontal warehouse is divided into a plurality of areas along the length direction, and when a certain area or certain areas are selected for material distribution, the material distribution gates of the rest areas are kept closed.

Each material distribution gate in the selected material distribution area is opened, the material falls down from the material distribution port 48a and the material distribution gate which are closest to the feeding end to form a natural material cone with high middle and low periphery, when the top of the material cone triggers the high material level sensor, the corresponding material distribution gate is closed, the material falls down from the material distribution port and the material distribution gate in the lower stream to form the next natural material cone with high middle and low periphery, when the top of the material cone triggers the high material level sensor, the corresponding material distribution gate is closed, the material falls down from the material distribution port and the material distribution gate in the lower stream, and therefore the material distribution in the material distribution area is completed until the material distribution in the material distribution area is completed, and the state after the material inlet is completed is as shown in fig. 1 and fig. 2.

Discharging materials: as shown in figure 3, a grain delivery machine extending along the full width direction of the horizontal warehouse is adopted to automatically walk along the axis of the horizontal warehouse for discharging, the grain delivery machine walks while collecting the materials on two sides of the horizontal warehouse to the middle part, then the materials are sent to the feeding end of a bent scraper elevator 49 at the rear side of the grain delivery machine through an over-travel lifting mechanism, the bent scraper elevator 49 walks along the grain delivery machine and transversely sends the materials to the high position of the wall edge, the materials fall into a flat scraper conveyor 50 through an elephant trunk after flowing out of the upper end of the bent scraper elevator 49, and the flat scraper conveyor 50 is fixed at the high position of the wall and extends along the full length direction of the horizontal warehouse to send the materials out of the warehouse. Therefore, full-automatic delivery can be realized, and loading forklifts or other vehicles are prevented from entering the horizontal warehouse.

The bottom of the curved scraper elevator 49 is supported on the ground through wheels, the upper part of the curved scraper elevator 49 is supported on a track through rollers, the track is fixed on a wall support, and the wall support is shared with the flat scraper conveyor 50. The front side of the bent scraper lifter 49 is connected with the grain delivery machine and is driven by the grain delivery machine to advance.

Because the length of the grain delivery machine is longer, the condition that two ends of the grain delivery machine cannot be aligned to be delivered is easy to occur, in order to avoid the deflection in the advancing process, a plurality of pairs of correcting devices are symmetrically arranged on the walls of two sides of the horizontal warehouse, and when the two ends of the grain delivery machine are aligned with the correcting devices, the fact that the axis of the grain delivery machine is perpendicular to the axis of the horizontal warehouse is confirmed. The correcting device can be a proximity switch or a travel switch, if the left side of the grain delivery machine triggers the proximity switch, when the right side is not triggered, the left side is paused to advance, after the proximity switch on the right side is triggered, the two sides advance synchronously again, and the grain delivery machine is ensured to advance along the axis of the horizontal warehouse.

As shown in fig. 4 to 8, the grain delivery machine includes a main beam 31 extending in the width direction of the horizontal warehouse, and two main beams 31 are provided in parallel with each other. The front side and the rear side of the bottom of the main beam 31 are respectively provided with a transverse discharging auger 34, the periphery of an auger shaft of the transverse discharging auger 34 is wound with a helical blade, one end of each of the two transverse discharging augers 34 is driven by an auger main driving shaft 15, and the other end is connected with the driven main shaft 22. The middle part of the transverse discharging auger 34 is provided with a middle coaxial 34c, the middle coaxial 34c is used as a boundary, the rotating directions of the helical blades at two sides are opposite, the materials at two sides are simultaneously conveyed to the middle coaxial 34c, and the materials at the most edge can oppositely reach the discharging point at the middle coaxial 34c only by moving half of the horizontal warehouse.

For materials with strong caking property, hardening can occur after the materials are stored for several days, so that the common packing auger can not discharge materials, and the packing auger is usually only required to discharge materials, and the materials are still discharged by adopting a loading forklift. The outer edge of the spiral blade is provided with the cutting teeth 34a respectively, so that front hardened materials can be crushed, and the bin discharger has greater adaptability.

An adjustable upper shell 47 capable of adjusting the feeding amount of the packing auger is arranged above the two half-width parts of the transverse discharging packing auger 34 respectively, the lower edge of the adjustable upper shell 47 swings downwards to reduce the feeding amount of the transverse discharging packing auger 34, and swings upwards to increase the feeding amount of the transverse discharging packing auger 34, so that the feeding amount of the transverse discharging packing auger 34 is matched with the advancing speed of the grain delivery machine and the discharging amount of the middle discharging machine.

As shown in fig. 9 to 11, two sets of road wheels 1 are provided at the bottom of the main beam 31 with a midpoint as a boundary, and the road wheels 1 are respectively fixed at the middle of the traveling shaft 6.
