The bucket elevator has the advantages of large conveying capacity, high lifting height, stable and reliable operation and long service life. Bucket elevator elevators are adapted to transport powder, granular and small block non-polished and polished materials such as: coal, cement, stone, sand, clay, ore, crop seeds, and the like. Since the traction mechanism of the elevator is an endless chain, it allows the transport of materials with higher temperatures, but generally the material temperature does not exceed 250 ℃. Bucket elevators generally have a conveying height of up to 40 meters, with TG types of up to 80 meters.
The bucket elevator comprises a bucket elevator body, a material transmission mechanism arranged in the body, a feeding hopper arranged at one side of the lower end of the bucket elevator body, and a discharging hopper arranged above the bucket elevator body. The top of the feeding hopper is a feeding hole, and one side of the feeding hopper, which is close to the machine body, is a discharging hole and is communicated with the inner cavity of the machine body. The material transmission mechanism comprises a transmission chain, a driving sprocket, a driven sprocket and a material conveying hopper fixed on the transmission chain, wherein the transmission chain is sleeved on the driving sprocket and the driven sprocket, and the output end of the driving device is connected with the driving sprocket and drives the driving sprocket to rotate, thereby moving along with the transmission chain.
The feeding hopper comprises two side plates and an inclined plate, wherein the side plates are right-angle triangular plates, the inclined sides of the side plates are respectively connected with two sides of the upper inclined surface of the inclined plate, a feeding hole of the feeding hopper is arranged between right-angle sides parallel to the ground on the side plates, and a discharging hole of the feeding hopper is arranged between right-angle sides perpendicular to the ground on the side plates. The existing feeding hoppers are all fixed on the machine body in a welding mode. Because the feeding hopper is in a feeding state for a long time, the materials conveyed by the bucket elevator are continuously contacted with the sloping plate, and the sloping plate can be worn and reduced in thickness even when the inclined plate is used for a long time, so that the situation of broken holes occurs. At this time, the maintenance mode of both detaching the welded loading hopper and re-welding a new loading is very troublesome, which results in larger maintenance time and cost.
Meanwhile, the existing conveying hoppers are fixed on the transmission chain in a bolt connection mode, and as at least dozens of conveying hoppers are installed on the transmission chain, hundreds of bolts are correspondingly required to be installed. The repeated tightening installation mode is complex in steps and operation; and in the later maintenance, bolts are required to be loosened in sequence. In the threaded connection, after the screw teeth are corroded, the bolts are difficult to detach smoothly.

The present embodiment further describes the structure of the support shaft 21.
As shown in fig. 1 to 14, in the present invention, a pull tab 24 is provided on the support shaft 21 at an end remote from the hopper 17, the pull tab 24 being parallel to the axis of the support shaft 21, and one end thereof being connected to the support shaft 21.
Anti-slip lines are arranged on the pull tabs 24.
The pull tab is provided to facilitate pulling of the support shaft 21, thereby smoothly compressing the spring B20 and rapidly completing the disassembling or assembling work of the hopper.
Further, the pull tab 24, the support shaft 21 and the positioning shaft 22 are integrally formed, so that the strength of the component can be improved and the service life can be prolonged.
Example 5
In this embodiment, the positional relationship between the hopper and the positioning plate 19 is further described.
In the present invention, as shown in fig. 1 to 14, two end plates of the feed hopper 17 are respectively contacted with the positioning plates 19 adjacent thereto. When a gap exists between the conveying hopper and the positioning plate 19, vibration is generated due to motion transmission, so that the conveying hopper moves in the axial direction of the positioning shaft 22, and then the spring B20 is compressed, so that the position of the conveying hopper 17 is unstable; it is therefore preferable that the two end plates of the hopper 17 are in contact with the positioning plates 19 so that even if vibration occurs during movement, the hopper is restrained by the two positioning plates 19 in the positioning shaft axis direction, cannot move, and does not act on the positioning shaft 22, and thus cannot compress the spring B, so that the hopper 17 is in a stable position and operating state.
Example 6
The embodiment further describes the structure of the blind hole.
In the present invention, as shown in fig. 1-14, the cross section of the blind hole 25 is regular hexagon. The blind holes 25 may also be rectangular holes or elliptical holes.
Example 7
This embodiment further describes the fixation of both ends of the spring B20.
In the present invention, as shown in fig. 1 to 14, the spring B20 is a circular hook type cylindrical spiral extension spring B, and hanging lugs are respectively provided at the hole bottom of the large-diameter section hole and at one end of the positioning shaft 22 far from the hole bottom of the blind hole 25, and the circular hooks at both ends of the spring B20 are respectively hung on one hanging lug.
The two ends of the spring B20 are connected with corresponding components in a disassembling mode, and convenience in installation of the spring B20 is improved. Specifically, the spring B20 is firstly installed in the hole of the large-diameter section, and a hook at one end of the spring B is hung on a hanging lug at the bottom of the hole of the large-diameter section; then, one end, far away from the positioning shaft 22, of the supporting shaft 21 sequentially passes through the center hole and the small-diameter section hole of the spring B20; then the hook at the other end of the spring B is hung on the hanging lug on the positioning shaft 22.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not creatively contemplated by those skilled in the art within the technical scope of the present invention should be included in the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
