Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, in particular to an anti-blocking device for a bucket elevator. Background Art

[0002] Bucket elevators are widely used in the process links of material transportation and lifting in industries such as coal, chemical industry, metallurgy, building materials, and food. However, when transporting wet and sticky materials, the feeding port of the bucket elevator is prone to adhesion and blockage problems, affecting the stable operation of the equipment.

[0003] Currently, for the problem of blockage of bucket elevators, generally, a vibrator is added at the bottom plate of the feeding port, and the vibration is used to promote the material to slide downwards to avoid blockage. Despite taking various anti-blocking measures, a relatively high proportion of the bucket elevators put into use still have blockage problems. The reasons are as follows: the properties of the materials themselves and the material transportation volume vary greatly, the fixed inclination angle of the feeding port is difficult to adapt to various working conditions, and since the feeding port is firmly connected to the equipment, the stiffness of the equipment shell and the feeding port is good, and the amplitude generated by the vibrator is small and difficult to promote the falling of materials, resulting in poor application effects of the vibrator. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following uses specific examples to illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0018] Please refer to the attached Figure 1 and the attached Figure 2As shown in the figure, a bucket elevator anti-blocking device includes a bracket 1 and a trough 2 with an adjustable angle and arranged obliquely. A vibrator 6 is provided at the bottom of the trough 2. The vibrator 6 drives the trough 2 to vibrate, prompting the materials in the trough 2 to slide downward along the inclined direction more quickly, avoiding material blockage. A trough spring seat 4 is movably installed on the trough 2. At least two support spring seats 3 with different heights are movably installed on the bracket 1. The two support spring seats 3 with different heights are used to support the trough 2 and make the trough 2 form a certain inclined angle according to the height difference between the two support spring seats 3. The bracket 1 can be arranged above or below the trough 2. When the bracket 1 is installed above the trough 2, the bracket 1 is fixed on the floor of the elevator for hoisting the trough 2; if the bracket 1 is installed below the trough 2, the bracket 1 is fixed on the ground to support the trough 2; and the bracket 1 and the trough 2 are connected by a plurality of spring members 5. The two ends of the spring member 5 are respectively fixedly connected to the support spring seat 3 and the trough spring seat 4. The spring member 5 can increase the amplitude generated by the vibrator 6, which helps to improve the problem of material blockage at the feeding port when the bucket elevator transports wet and sticky materials;

[0019] At the same time, to further accelerate the movement of materials and prevent blockage at the feeding port 8 of the bucket elevator, the inclined angle of the trough 2 is adjustable. Preferably, an installation plate 10 is provided at the bottom of the trough 2. An activity groove 11 is provided on the installation plate 10 along the length direction. The trough spring seat 4 is movably arranged on the installation plate 10 along the activity groove 11 through the cooperation of a bolt and a nut. By loosening the nut, the trough spring seat 4 can be moved back and forth, and then the trough spring seat 4 is fixed by tightening the nut; a channel steel 12 is transversely arranged on the bracket 1. A plurality of installation holes for installing the support spring seat 3 are provided on the channel steel 12. An L-shaped ear plate 13 is fixed on the support spring seat 3. The L-shaped ear plate 13 is movably installed on the channel steel 12 through the cooperation of a bolt and the installation hole. By loosening the nut, the support spring seat 3 can be moved back and forth on the channel steel 12. Specifically, by simultaneously loosening the nuts on the trough spring seat 4 and the support spring seat 3, the two support spring seats 3 with different heights can be moved simultaneously. The trough spring seat 4 moves along the activity groove 11 accordingly. By controlling the distance between the two support spring seats 3 with different heights, the inclined angle of the trough 2 can be adjusted; and with different inclined angles, the force exerted by the trough 2 on the spring member 5 is also different, and thus the elastic force of the spring also changes with the angle; the operation is convenient, and it can be adjusted in time according to the falling of the materials in the bucket elevator, so that most of the materials can pass by relying on gravity, preventing material blockage and improving work efficiency.

[0020] The bottom and top of the trough body 2 are respectively connected to the feeding port 8 of the bucket elevator and the previous feeding equipment 9. Among them, seals 7 are provided between the trough body 2 and the previous feeding equipment 9 and between the trough body 2 and the feeding port 8 of the bucket elevator. The seals 7 are made of dust-proof cloth and play a role in sealing and dust-proofing. At the same time, preferably, the seals 7 are made of flexible materials, so that when the vibrator 6 drives the trough body 2 to vibrate, the displacement and vibration of the trough body 2 will not be restricted at the two ends of the trough body 2, ensuring the safe operation of the equipment.

[0021] In the above embodiment, preferably, the bottom plate and side plates of the trough body 2 are made of stainless steel, which is wear-resistant and not easy to adhere to materials, reducing the probability of sticking materials and avoiding material blockage.

[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0023] The above embodiments only express the specific implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation of the patent scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
