Description

Wheel pushing type shield delivery machine

Technical Field

The invention relates to a house bin discharger, in particular to a wheel-pushing shield bin discharger, and belongs to the technical field of bin dischargers.

Background

Fang Cang is a traditional relatively backward mode, but at present, a very large number of modes for storing grains, particles and wood sawdust are rectangular, the width of the storage yard is relatively wide and is usually 30-40 meters, the material pile is usually relatively high, and the depth is sometimes more than two hundred meters. The most common way to deliver the material from home and abroad is to use a loading vehicle for discharging the material. At present, the equipment for discharging the bulk goods is also available, but the investment cost is high, the equipment problems are more, the faults are high, and the loading truck is basically matched for working. 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 usual discharging modes at present are listed as follows:

1. discharging by a loading vehicle: 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 vehicle 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 vehicle, 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 centre or the right side in the house sets up the feed opening, is equipped with a plurality of gates on ground along the length direction of feed opening, and when ground auger walking ejection of compact, the gate is opened one by one. 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 barn cannot be transformed.

4. Ground scraper blade machine of delivering from bin: a blanking opening is arranged in the middle of the house, a plurality of gates are arranged on the ground along the length direction of the blanking opening, 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 house 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 house consists 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, and the technology and investment cannot be improved;

2. the blanking hole of the pit is required to be provided with a material blocking gate or a material blocking gate, and the longer the house is, the more the control gate opening parts are, the more easily damaged and the maintenance is often carried out; 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; fang Cang the ground 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 transverse discharging auger, the driven component is arranged at the other end of the transverse discharging auger, the main driving component drives the transverse 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 at two side walls of the house, 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 house is constructed by the track beams, so that the investment is greatly increased, the construction period is prolonged, the effective width of the house is reduced, the height of a material pile is limited, the storage space is reduced by more than one third, and the old house cannot be transformed.

6. After materials such as grain enter the room storehouse and store, the storage cycle is usually at least three years, and each room storehouse is independent to form a complete set of delivery machine in the tradition, and after each delivery, wait to store the material again, continue waiting more than three years and go out the material again, delivery machine's availability ratio is too low, and idle time is overlength, and investment cost is too high, maintains the maintenance and then break down more easily.

For materials with stronger 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 always abandoned for discharging, and the materials still return to the loading vehicle 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 shells 48 with adjustable auger feeding amount are respectively arranged above two halves of the transverse discharging auger 34, the lower edges of the adjustable upper shells 48 swing downwards to reduce the feeding amount of the transverse discharging auger 34, and swing 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. 6 to 8, 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. The ends of each group of walking shafts 6 are connected with each other through an Oldham coupling 7 and a connecting rod 8, and the Oldham coupling 7 can effectively reduce the installation accuracy of the connecting rod 8 while ensuring the transmission torque. The two sides of each group of travelling wheels 1 are respectively provided with a girder connecting plate 9 which is parallel to each other and perpendicular to the travelling shaft 6, the lower ends of the girder connecting plates 9 are respectively supported on the travelling shaft 6 through a bearing 10 with a seat, the upper ends of the girder connecting plates 9 at the two ends in each group are respectively welded between the opposite side walls of the two girders, and a girder 31 bears a delivery mechanism to support the travelling wheels 1 to advance or retreat.

The traveling main driving sprocket 3 drives the traveling driven sprocket 4 to rotate through a chain under the driving of the traveling driving gear motor 2, and the traveling driven sprocket 4 drives the traveling wheels 1 in the same group to advance or retreat through the traveling shaft 6.

The both ends of walking wheel 1 are equipped with flower disc 1a respectively, and the center of flower disc 1a is fixed with flange cover 1b respectively, and flange cover 1 b's center seat passes through the bolt fastening on walking axle 6, and flower disc 1a periphery evenly is equipped with along radial extending's flower disc caulking groove, evenly is connected with many connection diaphragm 1c between two flower disc 1a, and connection diaphragm 1c is L shape, and the perpendicular limit at each connection diaphragm 1c both ends inlays respectively in corresponding flower disc caulking groove and welds mutually, and the transverse limit at each connection diaphragm 1c both ends covers the periphery at flower disc 1a respectively.

The middle part of the travelling wheel 1 is also provided with a flower disc 1a, and the vertical edges of the middle parts of the connecting transverse plates 1c are respectively embedded in the flower disc caulking grooves to form left, middle and right supports, so that the strength and the rigidity are improved. Each nonmetal supporting wheel plate 1d and each wheel plate pressing plate 1e are symmetrically divided into two sections, and two ends of each nonmetal supporting wheel plate 1d are positioned between the middle flower disc 1a and the outer flower disc.

The vertical edges of the connecting transverse plates 1c are respectively pressed with nonmetal supporting wheel plates 1d which extend along the axial direction of the connecting transverse plates, the outer sides of the nonmetal supporting wheel plates 1d are respectively pressed with wheel plate pressing plates 1e, bolts penetrate through the wheel plate pressing plates 1e, the nonmetal supporting wheel plates 1d and mounting holes on the connecting transverse plates 1c to fixedly connect the wheel plate pressing plates 1e, the nonmetal supporting wheel plates 1d and the mounting holes on the connecting transverse plates, and the outer edges of the nonmetal supporting wheel plates 1d are higher than the connecting transverse plates 1c and the wheel plate pressing plates 1e and are distributed on the same circumference.
