As shown in fig. 1 and fig. 2, the wide material bed continuous conveying mechanism of the present invention includes a conveying head shaft 2c and a conveying tail shaft, wherein two ends of the conveying head shaft 2c are respectively provided with a head shaft chain wheel 2c1, and are supported on a rack through a head shaft bearing seat 2b, and two outer end heads of the conveying head shaft 2c are respectively driven by a main speed reducer 2 a; tail shaft chain wheels are respectively installed at two ends of the conveying tail shaft, the head shaft chain wheel 2c1 and the tail shaft chain wheel on the same side are connected with each other through a conveying chain 2d, and the loaded materials are conveyed in the direction of the conveying tail shaft to the conveying head shaft 2c.

The conveying mechanism adopts double-end driving, and the power output with large breadth is reliable and stable. The main speed reducers 2a on two sides synchronously drive the conveying head shaft 2c to rotate, the conveying head shaft 2c drives the conveying tail shaft to rotate through the head shaft chain wheel 2c1 and the conveying chain 2d, and the upper conveying chain drives the material bed to move to the discharging end where the conveying head shaft 2c is located.

A chain plate 2e is arranged between the conveying chains 2d at the two sides, and vent holes are uniformly distributed on the chain plate 2 e; and a plurality of chain plate hinge lugs are respectively arranged below the front side and the rear side of each chain plate 2e, the chain plate hinge lugs of adjacent chain plates are alternatively embedded and are jointly hinged on the chain plate long pins 2f, the working surface is kept flat, and two ends of each chain plate long pin 2f are respectively fixed on corresponding chain links of the conveying chains 2d on the two sides. During aerobic fermentation, air goes upward from the vent holes of the chain plates 2e and the gaps between adjacent chain plates and uniformly penetrates through the material layer.

As shown in fig. 2 and 4, spacer bushes 2g are respectively arranged between the outer sides of the link plates 2e and the conveying chain 2d, the spacer bushes 2g are symmetrically sleeved at two ends of each link plate long pin 2f, long pin rollers 2h are respectively arranged at two ends of part of the link plate long pins 2f, the long pin rollers 2h are fixed at the ends of the link plate long pins 2f through bearings and are uniformly arranged at intervals in the circumferential direction of the conveying chain 2 d; the bottoms of the long pin rollers 2h of the upper-layer chain links are respectively supported on the upper chain rails 1b, and the bottoms of the long pin rollers 2h of the lower-layer chain links are respectively supported on the lower chain rails 1c.

The conveying chain 2d bears the tension of the conveying system and drives the chain plates 2e to rotate back and forth, and the long pins 2f of each chain plate bear the weight of the chain plates 2e and the material layer. The traditional method is that the two ends of each chain plate long pin 2f slide on the rail, the sliding friction resistance is very large, the power configuration and investment of the driving conveying mechanism are large, and the energy consumption is high; the height, width and length of the material layer are limited, and the fermentation of the material bed with high material layer, wide material layer and long material layer can not be realized. The long pin rollers 2h are respectively arranged at the two ends of the long pin 2f of the chain plate of the conveying mechanism, the sliding friction is changed into 100 percent rolling friction, the ton energy consumption is reduced, the service life of the equipment is prolonged, and the productivity is greatly improved.

The support surface of the short channel steel 2e2 is flush with the lower edge of the chain plate hinge lug 2e1, so that the material bed is kept stable when the short channel steel 2e2 or the chain plate hinge lug 2e1 contacts with the support roller 3a.

The chain plate 2e and the chain plate long pin 2f bear heavy material layer, and the middle part is sunk due to the fact that the middle part is stressed most. For a material bed with larger width, two rows of roller support assemblies 3 are generally symmetrically arranged below the upper-layer chain plate, each row is uniformly arranged at intervals along the conveying direction of the conveying mechanism, and four-point rolling friction is formed in the width direction of the material bed. Along the conveying direction, short channel steel 2e2 is pressed on the supporting roller 3a to advance every few link plates 2e, so that the stress condition of the middle area is greatly improved, and the running resistance is greatly reduced. The supporting surface of the short channel steel 2e2 is downward, so that material accumulation is avoided; the material is not accumulated on the supporting roller 3a. Because the supporting condition of the middle area of the material bed is improved, the running resistance is reduced, and the material layer width can reach more than 4 meters.

The roller slide seat 3d is stressed in the width direction of the material bed in the working process very little, and mainly bears the weight of the upper chain plate 2e and the material layer and the friction force generated along the conveying direction, the weight borne by the roller slide seat 3d is transmitted to the bottom plate of the roller positioning seat 3e and the rack, and the front edge and the rear edge of the roller slide seat 3d are pressed by the roller positioning seat caulking grooves on the front side and the rear side of the roller positioning seat 3e, so that the roller slide seat 3d is reliably positioned.

The inner port of the roller positioning seat caulking groove facing the axis of the conveying mechanism is provided with a positioning seat backer 3f for sealing the roller positioning seat caulking groove, the inner edge of a roller sliding seat 3d is abutted against the corresponding positioning seat backer 3f, the lower part of a roller support lug 3c close to the outer side is screwed with two push rods 3g, the two push rods 3g extend outwards in parallel along the conveying width direction, the outer ends of the two push rods 3g respectively penetrate through unthreaded holes of a push rod fixing seat 3h, the outer end heads of the two push rods 3g are respectively screwed with push rod nuts 3i for locking the push rods 3g, and the push rod nuts 3i are respectively pressed on the inner side wall and the outer side wall of the push rod fixing seat 3h.

Because the roller supporting component 3 is positioned below the chain plate 2e, and a material layer with the thickness of 1 meter is arranged above the roller supporting component, the maintenance is very inconvenient, and if the maintenance is stopped, the disassembly range is too large, so that very great loss is brought. The outer end of the push rod 3g is only provided with a section of thread, and the polished rod section connected with the thread section can be slightly thinner. This application only need open the side wall access hole, unload the push rod nut 3i in the outside earlier, loosen the push rod nut 3i of inboard soon again, move back to the polished rod section of little minor diameter, then can pull out gyro wheel slide 3d from gyro wheel positioning seat 3e through two push rods 3g, when gyro wheel slide 3d slided to being close to the side wall access hole along horizontal cross guide rail 3j, can unscrew push rod 3g, take out gyro wheel supporting component 3.

After the supporting roller 3a is replaced, the roller slide seat 3d is placed on a horizontal transverse guide rail 3j, a push rod 3g penetrates through a unthreaded hole of a push rod fixing seat 3h and is screwed on the lower part of a roller support lug 3c, then the roller slide seat 3d is pushed to slide inwards along the horizontal transverse guide rail 3j through the push rod 3g, a groove at the bottom of the roller slide seat 3d is clamped on a tenon 3j1 arranged at the top of the horizontal transverse guide rail 3j, so that the roller slide seat 3d cannot deviate in sliding until the front edge and the rear edge of the roller slide seat 3d are embedded into roller positioning seat embedding grooves in the front and the rear of the roller slide seat 3d, and the front and rear positioning is obtained; and continuing pushing inwards, stopping when the inner edge of the roller sliding seat 3d collides with the positioning seat backer 3f to obtain positioning in the width direction, and screwing a push rod nut 3i to fix the push rod 3g. Therefore, the supporting roller 3a can be replaced on line, the material picking and production stopping are not needed, the equipment can be disassembled greatly, and the device is very fast and convenient.
