Description

An improved bucket elevator

technical field

The utility model belongs to the technical field of material lifting equipment, in particular to an improved bucket elevator with convenient maintenance and long service life.

Background technique

The bucket elevator is suitable for lifting from a low place to a high place. After the supply material is put into the hopper through the vibrating table, the machine automatically and continuously runs upwards. This type of hoist has less requirements on the types and characteristics of materials. It can not only lift general powdery and small granular materials, but also can lift materials with high abrasiveness. It has good sealing performance and less environmental pollution. The driving wheels of traditional bucket elevators are mostly connected to the motor by chains. When there are too many materials, the motor is easy to jam, causing the motor to burn out, and maintenance is troublesome. It is easy to damage the conveyor belt, thereby reducing the service life of the bucket elevator, and after a period of use, the conveyor belt is easy to loosen, causing the conveyor belt to fail to operate normally.

Utility model content

The purpose of the utility model is to provide an improved bucket elevator with convenient maintenance and long service life.

The purpose of this utility model is achieved in this way, comprising a housing, a discharge opening arranged on the upper part of the housing, a driving wheel and a lifting motor, a feeding inlet and a driven wheel arranged at the lower part of the housing, the driving wheel and the driven wheel Connected by a conveyor belt, a bucket is installed on the conveyor belt, and the lower part of the housing is symmetrically provided with a tensioning device. a chute, the slider is matched with the chute, a through hole is set in the middle of the slider, the two ends of the axle of the driven wheel are respectively fixed in the through hole of the slider through bearings, and the sliders are respectively connected to the hoist, The winch is connected with a tension motor, and the outer surfaces of the driving wheel and the driven wheel are provided with ribs.

The utility model can effectively adjust the tension of the conveyor belt by setting the tensioning device so that it will not be too tight or too loose, so as to ensure the normal operation of the conveyor belt; The friction between the driving and driven wheels and the conveyor belt increases the service life of the hoist.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings, but the utility model shall not be limited in any way, and any changes or improvements made based on the teaching of the utility model shall belong to the protection scope of the utility model.

As shown in Figure 1, the utility model includes a housing 1, a discharge port 4 arranged on the upper part of the housing 1, a driving wheel 5 and a lifting motor 13, a material inlet 3 and a driven wheel 6 arranged at the lower part of the housing 1, The driving wheel 5 and the driven wheel 6 are connected by a conveyor belt 7, a bucket 8 is installed on the conveyor belt 7, and a tensioning device is arranged symmetrically front and rear at the bottom of the housing 1, and the tensioning device includes a slide block 11, a hoist 12 and a Tighten the motor 14, the middle position of the lower part of the housing 1 is longitudinally symmetrically provided with a chute 2, the slider 11 cooperates with the chute 2, the middle position of the slider 11 is provided with a through hole, and the axle of the driven wheel 6 The two ends are respectively fixed in the through holes of the slider 11 through bearings, the slider 11 is respectively connected to the hoist 12, the hoist 12 is connected to the tightening motor 14, and the outer surfaces of the driving wheel 5 and the driven wheel 6 are provided with protrusions. Edge 10.

The slider 11 is a cube, and its outer surface is provided with lugs 15, and the lugs 15 extend to the left and right respectively along the four corners of the outer surface of the slider 11. Surface limit fit.

A draw ring 10 is arranged at the lower end of the slider 11 , and the draw ring 10 is connected with a cable of a winch 12 .

The stay cables of the winch 12 are steel ropes.
