The embodiment of the utility model provides a guide conveying device which is used for conveying materials. Specifically, the material guiding and conveying apparatus includes a conveying mechanism 10, a material guiding groove 20, a material guiding plate 30, and a driving mechanism 40, and the conveying mechanism 10 is configured to convey a material to a preset position along a conveying direction of the conveying mechanism 10. The material is guided to the conveying mechanism 10 under the action of gravity through the material guide groove 20, and then conveyed to a preset position by the conveying mechanism 10. The guide plates 30 include two guide plates 30 respectively disposed at two opposite sides between the guide chute 20 and the conveying mechanism 10, and the guide plates 30 may be hinged to one side of the guide chute 20 near the conveying mechanism 10, that is, the guide plates 30 are hinged to the bottom of the guide chute 20. According to the different rotating angles of the guide plates 30, the guide states of the guide plates 30 comprise a guide state and a transport state which are switched with each other, and the guide states of the guide plates 30 correspond to the process of guiding materials to the conveying mechanism 10 through the guide grooves 20, in the process, the guide plates 30 rotate relative to the guide grooves 20 and are contacted with the two opposite sides of the width direction of the conveying mechanism 10 so as to achieve shaping and gathering of the materials, wherein the width direction of the conveying mechanism 10 refers to the direction that the left side and the right side face each other when facing the conveying direction. When the guide plates 30 are in contact with two opposite sides of the conveying mechanism 10 in the width direction, the guide plates 30 are in a vertical or near vertical state at this time, so that gaps between edges of two sides of the guide groove 20 and the driving mechanism 40 can be shielded, shaping and gathering of materials are realized, and leakage of materials from two opposite sides of the conveying mechanism 10 in the width direction in the process of guiding the materials from the guide groove 20 to the conveying mechanism 10 is avoided. After the material is guided to the conveying mechanism 10, the guide plate 30 is switched to a transportation state, the guide plate 30 rotates from a vertical state or a nearly vertical state to a horizontal state or a nearly horizontal state, so that the guide plate 30 and the conveying mechanism 10 are converted into a separation state from a contact state, then the conveying mechanism 10 starts to work, the material is conveyed along the conveying direction of the conveying mechanism 10 to a preset position, the guide plate 30 is separated from the conveying mechanism 10, the situation that the guide plate 30 and the conveying mechanism 10 are rubbed in the working process of the conveying mechanism 10 to cause damage to the guide plate 30 and the conveying mechanism 10 can be avoided, and on the other hand, the situation that the material is again contacted with the guide plate 30 to cause material scattering can be avoided. The driving mechanism 40 is used for driving the deflector 30 to rotate so as to switch between a vertical state and a horizontal state, so as to switch the deflector 30 between a deflector state and a transportation state.

Through the arrangement of the embodiment, the situation that materials leak from two sides in the width direction in the process of guiding the materials from the guide chute 20 to the conveying mechanism 10 can be effectively avoided.

In some embodiments, the guide chute 20 may be an open guide chute body or a closed guide chute.

In some embodiments, the bottom of the guide chute 20 may be welded with a cross beam disposed at two sides with respect to the width direction of the conveying mechanism 10, and then the guide plate 30 is hinged to the cross beam. When the driving mechanism 40 drives the deflector 30, the deflector 30 can rotate around the beam, so that the deflector 30 can be switched between the deflector state and the transportation state.

In some of these embodiments, deflector 30 may be hinged to deflector slot 20 by a hinge.

In some of these embodiments, the drive mechanism 40 includes a drive member 401 and a push rod 402, the drive member 401 driving the push rod 402 away from or toward the baffle 30 such that the baffle 30 contacts the conveyor mechanism 10 or is separate from the conveyor mechanism 10. In the above embodiment, the driving member 401 drives the push rod 402 to move, and when the push rod 402 is far away from the baffle 30, the baffle 30 is turned into a vertical or near vertical state under the action of gravity, so that the baffle 30 contacts with two sides of the conveying mechanism 10 in the width direction, so as to switch the diversion state of the baffle 30, so as to implement the diversion process of the material; when the deflector 30 is switched from the diversion state to the transportation state, the driving member 401 drives the push rod 402 to approach the deflector 30, and the deflector 30 is rotated from the vertical or near-vertical state to the horizontal or near-horizontal state under the pushing of the push rod 402, so that the deflector 30 is separated from the conveying mechanism 10, and then the transportation process of the materials from the conveying mechanism 10 is performed. The drive mechanism 40 may be controlled by a control box 403.

In other embodiments, the drive mechanism 40 may employ an electric pushrod driven by a drive motor to perform the operation. Two electric pushing rods can be arranged, and each electric pushing rod drives one guide plate 30 to rotate. Illustratively, the electric push rod can be a DT500-200 type electric push rod, which is provided with two travel switches, is provided with an independent control box 403, and is operated in situ, wherein the control box 403 protects the grade IP 65; power supply cables 4 x 2.5mm copper core cables are laid, and the output end of the control box 403 is connected with the input end of the power mechanism.

In other embodiments, the deflector 30 may be directly rotatably connected to a driving motor, and the driving motor directly drives the deflector 30 to rotate, so as to switch the deflector 30 between the deflector state and the transportation state.

In some of these embodiments, the conveyor mechanism 10 includes a conveyor belt 101, and material is directed onto the conveyor belt 101 by a chute 20 and then conveyed by the conveyor belt 101 in its direction of travel.

In some embodiments, when the conveyor belt 101 adopts an inward concave shape, the closer to the edge of the conveyor belt 101, the closer the distance between the conveyor belt 101 and the guide chute 20, at the most edge, because the distance between the conveyor belt 101 and the guide chute 20 is sufficiently close, there may be a situation that the material is stuck between the conveyor belt 101 and the guide chute 20, so that the conveyor belt 101 is scratched by the material during the working process, and at this time, by the arrangement of the guide plate 30, the material can be prevented from reaching the edge of the conveyor belt 101, and further, the situation that the material is stuck between the conveyor belt 101 and the guide chute 20 is avoided; on the other hand, when the flow guiding state of the flow guiding plate 30 is switched to the transportation state, the flow guiding plate 30 can be set to rotate inwards, so that the material close to the edge of the conveying belt 101 is pushed to move towards the middle of the conveying belt 101, the possibility that the material damages the conveying belt 101 is further avoided, and meanwhile the condition that the material leaks is avoided.

In some of these embodiments, the conveyor 10 further includes three sets of idlers 102, with the conveyor 101 disposed on the idlers 102, each set of idlers 102 including a plurality of idlers 102 disposed in series along the conveying direction of the conveyor 10, the three sets of idlers 102 being disposed side by side along the width direction of the conveyor 10, with two sets of idlers 102 near the edges being disposed obliquely upward so that the conveyor 101 disposed on the three sets of idlers 102 can form an inwardly concave shape. In the working process, the conveyor belt 101 is driven by the driving motor to move in the transmission direction under the support of the carrier roller 102.

In some of these embodiments, the lead conveyor apparatus further includes a frame 50, and three sets of idlers 102 are each rotatably retained on the frame 50. In a specific example, three sets of idler rollers 102 may be respectively provided with a support frame, and the idler rollers 102 may be rotatably connected with the support frame, and the support frame is connected with the frame 50 through a connecting rod. With this arrangement, the integrity of the conveying mechanism 10 can be improved.

In some of these embodiments, the housing 50 is coupled to the drive mechanism 40. Through the arrangement, the guide conveying equipment has better integrity.

In some embodiments, a sealing tape is arranged between the guide chute 20 and the conveying mechanism 10, and the sealing tape is arranged on the outer side of the guide plate 30. Sealing adhesive tapes are arranged between the guide chute 20 and the conveying mechanism 10, and mainly are arranged between two sides of the conveying mechanism 10 in the width direction and the guide chute 20, so that the situation that materials leak from a gap between the guide chute 20 and the conveying mechanism 10 in the process of guiding the materials from the conveying mechanism 10 through the guide chute 20 is avoided.

When conveying structure adopts inwards sunken conveyer belt 101 to set up the sealing tape, at the circumstances of material card between conveyer belt 101 width direction's edge and baffle box 20, the in-process of material transmission on conveyer belt 101 also can cause the damage to the sealing tape, leads to the frequent change of sealing tape, through the setting of guide plate 30, also can effectively avoid the condition of the damage of material to the sealing tape.

The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model in any way, and any simple modification, equivalent variation, etc. of the above embodiment according to the technical matter of the present utility model fall within the scope of the present utility model.
