[0002] Bucket elevators are commonly used vertical lifting equipment, suitable for vertical lifting of dry bulk powder materials or materials.

[0003] During operation, the hopper scoops up the material from the lower storage, lifts it to the top along with the conveyor belt or chain, turns downward after bypassing the top wheel, and the bucket elevator pours the material into the receiving chute. The conveyor belt of the belt-driven bucket elevator generally uses a rubber belt, which is installed on the lower or upper driving drum and the upper and lower redirecting drums.

[0004] Among them, the drum is the core component of the belt elevator and the head driving component of the belt elevator, and it has relatively high requirements for strength and stiffness. Generally, most drums are cylindrical structures, but drums with this structure are prone to deviation during operation, thus affecting the efficiency and stability of the elevator.

The drum has a drum-shaped structure, and an annular groove is provided on the outer peripheral surface of the drum, and the annular groove cooperates with a protrusion provided on the inner ring of the belt.

[0007] Preferably, there are two drum webs on the left and right inside the drum. The two drum webs on the left and right are respectively fixedly connected to the head shaft and the mounting shaft through drum expansion coupling sleeves. Bearings are provided on both the head shaft and the mounting shaft, and bearing seats fixedly provided on the head housing are provided on the bearings.

[0008] Preferably, an inspection door is provided on one side of the head housing.

[0009] Preferably, anti-deviation detection devices are provided on both the left and right sides of the head housing.

[0010] Preferably, the anti-deviation detection device includes a hinge plate, a proximity switch, a roller and a spring. The upper end of the hinge plate is movably connected to the head housing. A proximity switch is provided at the lower end of the hinge plate. A roller corresponding to one edge of the belt is provided on the hinge plate. A spring pressing on the hinge plate is provided on the head housing.

[0011] Preferably, a support body pressing on a spring is provided on the loose-leaf board.

[0012] Advantages of the present utility model: By adopting a drum-shaped structure for the drum and providing an annular groove on the outer peripheral surface of the drum, and matching the annular groove with a protrusion provided on the inner ring of the belt, compared with the prior art, the present utility model can reduce the deviation during operation and improve the efficiency and stability of the elevator.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a head structure of an anti-deviation belt elevator of the present utility model includes a drum 1, the drum 1 has a drum-shaped structure, and an annular groove 2 is provided on the outer peripheral surface of the drum 1, and the annular groove 2 is matched with a protrusion 4 provided on the inner ring of the belt 3.

[0020] Two drum webs 5 are provided inside the drum 1, and the two drum webs 5 on the left and right are respectively fixedly connected to the head shaft 7 and the mounting shaft 8 through drum expansion coupling sleeves 6, bearings 9 are provided on both the head shaft 7 and the mounting shaft 8, and bearing seats 11 fixedly provided on the head housing 10 are provided on the bearings 9.

[0021] An inspection door 12 is provided on one side of the head housing 10.

[0022] Anti-deviation detection devices 13 are provided on both the left and right sides of the head casing 10.

[0023] The anti-deviation detection device 13 includes a hinge plate 131, a proximity switch 132, a roller 133, and a spring 134. The upper end of the hinge plate 131 is movably connected to the head casing 10. The proximity switch 132 is provided at the lower end of the hinge plate 131. A roller 133 corresponding to one edge of the tape 3 is provided on the hinge plate 131. A spring 134 pressing on the hinge plate 131 is provided on the head casing 10.

[0024] A support 135 pressing on the spring 134 is provided on the hinge plate 131.

[0025] Working process of the present utility model:

[0026] In the working process of the head structure of the anti-deviation tape hoist of the present utility model, the drum 1 is of a drum-shaped structure. When the tape moves forward and deviates from the center line, due to the drum-shaped design, thicker in the middle and thinner at both ends, when the drum rotates one circle, the speed in the middle is different from that at both ends. Therefore, the differential effect of the drum produces a deviation-correcting force, realizing the tracking and deviation correction of the tape. An annular groove 2 is provided on the outer peripheral surface of the drum 1, and the annular groove 2 cooperates with the protrusion 4 provided on the inner ring of the tape 3. The protrusion 4 is embedded in the annular groove 2, enabling the tape to run stably on the drum 1 and greatly preventing the tape 3 from deviating.

[0027] The anti-deviation detection device 13 is used to detect the deviation of the tape 3. When the tape 3 deviates, the tape 3 pushes the corresponding roller 133, and the roller 133 pushes the hinge plate 131 to rotate so that its lower end moves away from the head casing 10. The hinge plate 131 drives the proximity switch 132 to move so that it cannot sense the head casing 10. At this time, the proximity switch 132 sends a signal to the PLC controller, and the PLC controller controls the alarm to work.

[0028] The above embodiments are illustrative of the present utility model, not restrictive thereof. Any simple transformation of the present utility model belongs to the protection scope of the present utility model.
