In addition, the chain conveyor and the roller conveyor can transport the hopper in two mutually perpendicular directions in the horizontal direction, reversing operation on the hopper can be completed, functions are diversified, and the traditional single chain conveyor or roller conveyor can only carry out single-direction transportation and does not have reversing function.

Further, the chain conveyor comprises a third chain, a driving sprocket and a driven sprocket which are arranged at two ends of the third chain, and a second motor reducer connected with the driving sprocket. The method comprises the following steps: the second motor speed reducer drives the driving sprocket to rotate, and the driving sprocket drives the driven sprocket to synchronously rotate through the third chain, so that the conveying of the third chain feeding hopper is completed, and the structure is simplified, the operation is convenient, and the maintenance is convenient.

Further, the roller conveyor comprises a plurality of rollers arranged on two adjacent sides of the third chain and a power mechanism for driving the rollers to rotate; the roller is parallel to the third chain. The power mechanism drives the roller to rotate, so that a hopper on the roller is driven to transport on the roller; the rollers are parallel to the third chain, i.e. the conveying direction of the roller conveyor is perpendicular to the conveying direction of the chain conveyor.

Further, the roller comprises at least two driving rollers and a plurality of driven rollers which are oppositely arranged, a first chain wheel is arranged at the end part of each driving roller, and the opposite driving rollers are connected through a transmission shaft; the power mechanism comprises a third motor speed reducer and a fourth chain which are arranged on the roller conveyor, the third motor speed reducer is connected with the first chain wheel through the fourth chain, a second chain wheel is arranged on the roller, and adjacent rollers are connected through a fifth chain.

The first air cylinder drives the chain conveyor to lift in the vertical direction through the push arm, the lifting rotating shaft, the lifting torsion arm and the lug plate in sequence; through the corresponding structure, the first cylinder is horizontally arranged on the roller conveyor, so that the occupied area of the first cylinder is reduced under the action of the supporting force of the chain conveyor. If a traditional vertical mode is adopted, the fixed end of the first air cylinder is connected with the roller conveyor, and the movable end of the first air cylinder is connected with the chain conveyor, so that a piston rod of the first air cylinder is directly stressed, and the piston rod is easy to damage; further, the vertical arrangement requires an increase in the distance between the roller conveyor and the flight conveyor, resulting in an increase in the occupied area of the apparatus. The utility model therefore horizontally arranges the first cylinder on the roller conveyor and drives the chain conveyor to lift by the corresponding force transmission component.

Further, the outer side of the lifting rotating shaft is provided with a second bearing fixedly connected with the roller conveyor, so that the stress point and the stress area of the lifting rotating shaft are increased, and the stable rotation of the lifting rotating shaft is ensured.

Further, a third lifting mechanism for driving the second baffle to lift is arranged on the chain conveyor. The second baffle plate plays a role in guiding and limiting a hopper on the chain conveyor, so the baffle plate is arranged above the third chain. When the hopper is transported on the roller conveyor, the chain conveyor is hidden on the roller conveyor, that is, the upper surface of the chain conveyor is lower than the upper surface of the roller. If the fixed second baffle is adopted, the second baffle needs to be hidden on the roller conveyor, that is, the upper surface of the second baffle is lower than the upper surface of the roller, so that the stroke of the first lifting mechanism is increased, that is, the overall height and the occupied area of the roller conveyor are increased. Therefore, the utility model skillfully sets the third lifting mechanism for driving the second baffle to lift, and the second baffle stretches out when the chain conveyor transports materials; when the chain conveyor is not transporting material, the second baffle is retracted. After the second baffle is retracted, the second lifting mechanism only needs to drive the upper surface of the third chain of the chain conveyor to be lower than the upper surface of the roller. The stroke of the second lifting mechanism is shortened, namely the overall height and the occupied area of the roller conveyor are reduced.

The guide shaft plays a guiding role in the lifting process of the second baffle, and avoids the inclination of the second baffle in the lifting process.

Further, the chain conveyor is provided with an adaptive tensioning mechanism for automatically tensioning the third chain. The chain conveyor is a mechanical mechanism, and the chain is deformed due to friction among all parts along with the time; in addition, the chain can deform due to long-term heavy-load running. The size increases after the chain deformation, leads to the chain not hard up, influences the normal transportation of hopper. The traditional maintenance method comprises the following steps: the machine is stopped firstly, then the chain is replaced or the distance between the driving chain wheel and the driven chain wheel is manually adjusted, so that the chain is in a tensioning state, and the normal transportation of the hopper is ensured. The traditional mode has the advantages of high labor intensity, low working efficiency and high cost. The self-adaptive tensioning mechanism can automatically tension the third chain, can ensure that the tensioning force is consistent with the looseness of the third chain, prolongs the service life and the production efficiency of equipment, reduces the manual labor and the production cost, and has simple structure and convenient installation.

Further, a long hole is horizontally arranged on the chain conveyor, a rotating shaft of the driven sprocket is arranged in the long hole, a tensioning shaft is arranged at the end part of the rotating shaft in a penetrating manner, and a spring is arranged on the tensioning shaft; the tensioning shaft is movably connected with the rotating shaft. Because the rotating shaft of the driven sprocket is movably arranged in the long hole, the driven sprocket can move in the range of the long hole, and the rotating shaft is abutted against one side of the long hole through the spring arranged on the tensioning shaft, so that the driven sprocket is fixed. With the increase of the working time of the chain plate conveyor, the third chain is abraded between the driving wheel and the driven wheel, so that the third chain is loosened, and the driven sprocket can be pushed to be far away from the driving sprocket through the spring arranged on the tensioning shaft, so that the distance between the driving sprocket and the driven sprocket is increased, and the effect of tensioning the third chain is achieved. Compared with the traditional manual replacement or adjustment mode, the self-adaptive tensioning mechanism can automatically tension the third chain, can ensure that the tensioning force is consistent with the looseness of the third chain, improves the service life and the production efficiency of equipment, reduces the manual labor and the production cost, and has the advantages of simple structure and convenience in installation.

Further, the tensioning shaft is detachably connected with the chain conveyor, so that the tensioning shaft can be conveniently and quickly assembled and disassembled.

Further, the tensioning shaft is a tensioning screw rod, two ends of the tensioning screw rod are connected with the chain conveyor through the first tensioning plate and the second tensioning plate respectively, nuts are arranged at the ends of the tensioning screw rod, that is, the tensioning screw rod is connected with the lifting frame through bolts, and the tensioning screw rod has the advantage of being fast in disassembly and assembly.

Further, the lifting frame comprises a positioning mechanism for fixing the lifting frame and the frame. When the lifting frame reaches a high station and the hopper on the lifting frame is required to be output, the first lifting mechanism is stopped, and the hopper is horizontally output through the chain conveyor. In the process of hopper output, the gravity of the hopper is completely borne by the first chain and the second chain, so that the first chain and the second chain are greatly damaged, the first chain and the second chain are deformed, the lifting frame is inclined after deformation, and the hopper output is blocked; what is more, the first chain and the second chain are broken, which causes serious damage to the hopper, the lifting frame and the frame. Therefore, the positioning mechanism is arranged, and after the hopper is lifted in place, the positioning mechanism fixes the lifting frame and the frame, so that the first chain and the second chain are prevented from being stressed, the first chain and the second chain are protected, the service lives of the first chain and the second chain are prolonged, and the hopper, the lifting frame and the frame are protected.

Example III

Referring to fig. 7, in the second embodiment, an adaptive tensioning mechanism 8 for automatically tensioning a third chain 401 is provided on a chain conveyor. The chain conveyor is a mechanical mechanism, and the chain is deformed due to friction among all parts along with the time; in addition, the chain can deform due to long-term heavy-load running. The size increases after the chain deformation, leads to the chain not hard up, influences the normal transportation of hopper. The traditional maintenance method comprises the following steps: the machine is stopped firstly, then the chain is replaced or the distance between the driving chain wheel and the driven chain wheel is manually adjusted, so that the chain is in a tensioning state, and the normal transportation of the hopper is ensured. The traditional mode has the advantages of high labor intensity, low working efficiency and high cost. The self-adaptive tensioning mechanism can automatically tension the third chain, can ensure that the tensioning force is consistent with the looseness of the third chain, prolongs the service life and the production efficiency of equipment, reduces the manual labor and the production cost, and has simple structure and convenient installation.

Because the rotating shaft of the driven sprocket is movably arranged in the long hole, the driven sprocket can move in the range of the long hole, and the rotating shaft is abutted against one side of the long hole through the spring arranged on the tensioning shaft, so that the driven sprocket is fixed. With the increase of the working time of the chain plate conveyor, the third chain is abraded between the driving wheel and the driven wheel, so that the third chain is loosened, and the driven sprocket can be pushed to be far away from the driving sprocket through the spring arranged on the tensioning shaft, so that the distance between the driving sprocket and the driven sprocket is increased, and the effect of tensioning the third chain is achieved. Compared with the traditional manual replacement or adjustment mode, the self-adaptive tensioning mechanism can automatically tension the third chain, can ensure that the tensioning force is consistent with the looseness of the third chain, improves the service life and the production efficiency of equipment, reduces the manual labor and the production cost, and has the advantages of simple structure and convenience in installation.

Referring to fig. 8, the tensioning shaft 803 of the present embodiment is detachably connected to the chain conveyor 4, so that the tensioning shaft can be quickly attached and detached.

Referring to fig. 8, the tensioning shaft 803 of the present embodiment is a tensioning screw, two ends of the tensioning screw are connected to the chain conveyor through the first tensioning plate 805 and the second tensioning plate 806 respectively, and nuts 807 are disposed at the ends of the tensioning screw, that is, the tensioning screw is connected to the lifting frame by bolts, which has the advantage of quick assembly and disassembly.

Example IV

Referring to fig. 1 and 4, on the basis of the first embodiment, the present embodiment further includes a positioning mechanism for fixing the lifting frame and the frame. When the lifting frame reaches a high station and the hopper on the lifting frame is required to be output, the first lifting mechanism is stopped, and the hopper is horizontally output through the chain conveyor.

Therefore, the positioning mechanism is arranged, and after the hopper is lifted in place, the positioning mechanism fixes the lifting frame and the frame, so that the first chain and the second chain are prevented from being stressed, the first chain and the second chain are protected, the service lives of the first chain and the second chain are prolonged, and the hopper, the lifting frame and the frame are protected.

Referring to fig. 4, the positioning mechanism of the present embodiment includes a positioning rod 901 disposed at an upper portion of a frame, a positioning plate 903 hinged to a lifting frame, and a third cylinder 902 having one end fixedly connected to the lifting frame and the other end connected to the positioning plate 903; a pinch plate 904 which can be lapped on the lifting frame through rotation is arranged on one side of the positioning plate, which is close to the lifting frame; the third cylinder can drive the locating plate to rotate in the vertical direction and lap on the locating rod. After the lifting frame ascends to a high station, the third cylinder drives the positioning plate to rotate, and the positioning plate is lapped on the positioning rod after rotating; meanwhile, the buckle plate synchronously rotates and is lapped on the lifting frame, the interaction force of the buckle plate and the lifting frame avoids the stress of the third cylinder, and the connection stability of the lifting frame and the frame is improved.
