Description

Method for feeding and discharging granular materials into pit-free bungalow warehouse

Technical Field

The invention relates to a horizontal warehouse discharging machine, in particular to a warehouse entering and exiting method of pit-free horizontal warehouse granular materials, and belongs to the technical field of discharging machines.

Background

The horizontal warehouse is widely applied to the storage of bulk materials (soybean, rapeseed, soybean meal, rapeseed meal and the like), and has the advantages of flexible storage, low civil engineering investment cost and the like. The stock yard is rectangular, the width of the stock yard is wider and is usually 30-40 meters, the stock pile is usually higher, and the depth is sometimes more than two hundred meters. The traditional most common discharging mode is that a worker drives a forklift to load materials into pit conveying equipment and a truck carriage, so that great potential safety hazards exist, and great demands are made on automatic discharging of square bins. At present, the equipment is also provided with the unloading equipment, but the investment cost is high, the equipment problems are more, the faults are high, and the equipment is basically matched with the loading forklift to work. The track, the sealed processing of unloading, the gallery design is too loaded down with trivial details, can't realize real automatic ejection of compact. The current common method for discharging bins is listed as follows:

1. discharging of the loading forklift: the material is pushed to the middle blanking opening, the blanking opening is provided with a plurality of gates on the ground along the length direction, and when the material is discharged, the gates are opened one by one, and the loading forklift pushes the material to the blanking opening for blanking. The defects are as follows: the manual driving into the bin has extremely bad personnel operation environment, the material is polluted by the loading forklift, and the danger of dust explosion exists; the discharge gate sets up a plurality of door blocking mechanism, and the trouble is many. When discharging, the bin gate is opened, the water loss is fast, the total weight of the materials is obviously reduced in a large amount, and the economic loss of customers is caused.

2. Cabin top suspension discharging machine: the feed opening length direction is equipped with a plurality of gates on subaerial, and during the ejection of compact, opens one by one, hangs the material to the side from top to bottom with the material machine of hanging. 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 low; and overhead maintenance is difficult; the ejection of compact rocks and has the risk that drops, and old storehouse can't reform transform.

3. Ground auger delivery machine: the left side, the middle or the right side of the bungalow storehouse 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: the motor side and the driven side cannot have materials, and the warehouse capacity is reduced by more than 1/3; the discharging pit equipment is difficult to maintain; the number of the gates of the feed opening is large, and the number of maintenance and fault points is too large; the track is easy to climb teeth or derail when running along the track; the residual quantity of the driven side leaning wall is large; the auger is hung more, the strength is poor, and the material can not be discharged after being slightly hardened; once the driving is buried by landslide materials, the driving cannot be started, and the existing bungalow warehouse cannot be transformed.

4. Ground scraper blade machine of delivering from bin: a blanking port is arranged in the middle of the horizontal warehouse, a plurality of gates are arranged on the ground along the length direction of the blanking port, and the gates are opened one by one when the ground scraping plate horizontally moves for discharging; the middle part is arranged in the motor drive, and the pit top sets up similar umbelliform and keeps off 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 reform transform. The discharging pit equipment is difficult to maintain; the number of the gates of the feed opening is large, and the number of maintenance and fault points is too large; the sprocket and the chain drive the walking to be easy to block the shell and remove the teeth; the friction force of the plane is large, and the plane is easy to be blocked; the return material on the scraper chain cannot be handled.

In summary, the existing bin discharger has the following disadvantages:

1. pit must be dug, equipment under the pit is difficult to maintain, and the cost is high; the ground of the old bungalow 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 destroyed, a pit is additionally arranged along the axis, the overall structure and the stability of the square house are greatly influenced, and the square house cannot be modified in technology and investment;

2. the blanking hole of the pit must have a material blocking gate or a material blocking gate, and the longer the bungalow, the more the gate is, the more the control gate opening pieces are, so that the pit is extremely easy to damage and is frequently maintained; in the sliding contact line, the air pipe and the pit, faults frequently occur due to excessive dust, and sparks are easily caused by poor contact of the sliding contact line, so that the risk of dust explosion is increased;

3. the track is buried in the material, the track is filled with the material, so that the phenomenon of tooth climbing or derailment is easy to occur, and the recovery is difficult; the ground of the horizontal warehouse is formed by pouring concrete, and certain error exists in levelness due to large area; the rails are steel structural members and are subject to high points on the front side and the rear side, so that synchronous fluctuation along with the ground is not possible, and when the bin discharger normally walks along the rails, the gap between the transverse discharging auger and the ground is easily oversized, so that excessive residual materials are caused;

4. The cabin machine rail on the suspended ceiling is suspended on the beam, so that the maintenance is not easy, and the risk of falling is caused;

5. the main driving component is arranged at one end of the horizontal discharging auger, the driven component is arranged at the other end of the horizontal discharging auger, the main driving component drives the horizontal discharging auger to rotate, the main driving component and the driven component all need to occupy a certain space, a track beam is generally constructed on two side walls of the horizontal warehouse, the top of the track beam is horizontal, and the lower part of the track beam is hollow. The travelling device is supported at the top drive delivery machine of track roof beam and advances or retreats, and auger drive assembly arranges the below of track roof beam in, and the inboard border of track roof beam is equipped with the skirtboard of sagging to prevent the space that the material got into drive assembly and is located, the height of windrow both sides can not be higher than the top of track roof beam. The new bungalow is constructed by the track beam, so that the investment is greatly increased, the construction period is prolonged, the effective width of the bungalow is reduced, the height of a material pile is limited, the storage space is reduced by more than one third, and the old bungalow cannot be transformed.

6. After materials such as grain enter the bungalow storehouse and store, the storage cycle is usually at least three years, each bungalow storehouse is independent to form a complete set of delivery machine conventionally, after delivering from the storehouse each time, wait to store the material again, continue to wait for more than three years and discharge again, the utilization ratio of delivery machine is too low, idle time is too long, investment cost is too high, maintenance is not enough then more easy to break down.

Detailed Description

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

The invention relates to a method for feeding and discharging granular materials in a pit-free bungalow, which comprises the following steps:

feeding materials into a bin: the materials outside the bin are sent into the scraper spreader 48, the scraper spreader 48 is arranged below the peak of the flat bin and extends along the length direction of the flat bin, a plurality of distributing openings 48a are uniformly formed in the bottom plate of the scraper spreader 48, a distributing gate below the distributing openings 48a is opened, the materials are freely scattered on the ground to form a cone, and when the top of the cone approaches the distributing gate, the distributing gate is closed.

The scraper spreader 48 extends from a plurality of end-to-end connection relay, the feeding end of the downstream scraper spreader is positioned below the discharging end of the upstream scraper spreader, and a high material level sensor lower than the lower port of each material spreading gate is respectively arranged below one side of each material spreading gate; the cloth gates in the safe distance range of the front side and the rear side of the bin discharger are always kept closed. I.e. the material piles at the front and back sides of the bin discharger can not be buried after natural collapse. For example, if the natural angle of the cone of a certain material is 30 degrees, the safety distance between the cone and the bin discharger is reserved according to the natural angle. Dividing the horizontal warehouse into a plurality of areas along the length direction, and keeping the cloth gates of other areas closed when selecting cloth in one or more areas.

The material distribution gates in the selected material distribution area are opened, materials fall from a material distribution port 48a closest to the material inlet end and the material distribution gates to form a natural material cone with high middle and low periphery, when the top of the material cone triggers a high material level sensor, the corresponding material distribution gate is closed, the materials fall from a material distribution port and the material distribution gate at the lower side to form a 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, and the materials fall from a material distribution port and the material distribution gate at the lower side until the material distribution in the material distribution area is completed, and the state after the material inlet is completed is shown in fig. 1 and 2.

Discharging materials: as shown in fig. 3, the discharging machine extending along the full width direction of the flat warehouse is adopted to independently travel along the axis of the flat warehouse for discharging, the discharging machine walks while collecting materials on two sides of the flat warehouse to the middle part, then the materials are sent into the feeding end of the curved scraper lifter 49 on the rear side of the discharging machine through the over-travel lifting mechanism, the curved scraper lifter 49 follows the discharging machine to walk and transversely send the materials to the high position of the wall, after the materials flow out from the upper end of the curved scraper lifter 49, the materials fall into the flat scraper conveyor 50 through the chute, and the flat scraper conveyor 50 is fixed on the high position of the wall and extends along the full length direction of the flat warehouse to send the materials out of the warehouse. Thus, the full-automatic delivery can be realized, and loading forklift trucks or other vehicles are prevented from entering the flat warehouse.

The bottom of the curved blade elevator 49 is supported on the ground by wheels, the upper portion of the curved blade elevator 49 is supported on rails by rollers, the rails are fixed on a wall mount, and the wall mount is shared with the flat blade conveyor 50. The front side of the curved scraper elevator 49 is connected with the bin discharger and driven by the bin discharger to advance.

Because the length of the delivery machine is longer, the situation that the two ends are not aligned and enter is easy to occur, a plurality of pairs of correction devices are symmetrically arranged on the two side walls of the flat warehouse in order to avoid skew in the advancing process, and when the two ends of the delivery machine are aligned with the correction devices, the axis of the delivery machine is confirmed to be perpendicular to the axis of the flat warehouse. The correction device can be a proximity switch or a travel switch, if the left side of the delivery machine triggers the proximity switch, and when the right side is not triggered, the left side pauses to advance, and after the right side proximity switch is triggered, the two sides advance synchronously again, so that the delivery machine is ensured to advance along the axis of the bungalow.

As shown in fig. 4 to 8, the grain delivery machine includes a main beam 31 extending in the width direction of the flat grain delivery, and the main beam 31 is provided with two parallel beams. The front side and the rear side of the bottom of the main beam 31 are respectively provided with a transverse discharging auger 34, spiral blades are wound on the periphery of an auger shaft of the transverse discharging auger 34, one end of each transverse discharging auger 34 is driven by an auger main driving shaft 15, and the other end of each transverse discharging auger 34 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 spiral blades on two sides are opposite in rotation direction by taking the middle coaxial 34c as a boundary, materials on two sides are simultaneously conveyed to the middle coaxial 34c, and the materials on the most edge can reach the discharging point at the middle coaxial 34c in opposite directions only by advancing a half width of the bungalow.

For materials with strong cohesiveness, the materials are likely to be hardened after being stored for a few days, so that the common auger cannot discharge, and the auger is often abandoned for discharging, and the materials still return to the loading forklift for discharging. The outer edges of the helical blades are respectively provided with the cutting teeth 34a, so that the front hardened materials can be crushed, and the bin discharger has higher adaptability.

The upper parts of the two halves of the transverse discharging auger 34 are respectively provided with an adjustable upper shell 47 with adjustable auger feeding amount, the lower edge of the adjustable upper shell 47 swings downwards to reduce the feeding amount of the transverse discharging auger 34, and swings upwards to increase the feeding amount of the transverse discharging auger 34, so that the feeding amount of the transverse discharging auger 34 is matched with the advancing speed of the bin discharger and the discharging amount of the middle discharger.

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