Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a crawler conveying device for a feeder. Background Art

[0002] Feeders are mainly used for short-distance transportation of bulk materials such as coal and stones. Currently, there are two main types of feeders: belt feeders and chain feeders. Belt feeders use belts to transport materials, while chain feeders use crawler tracks composed of armor plates to transport materials. Since the armor plates are mainly made of metal materials, chain feeders are more durable and are gradually replacing belt feeders. Belt feeders rely on the friction between the belt and the roller for transmission, while chain feeders mainly rely on sprockets and roller chains on both sides of the crawler track for transmission. Using roller chains for transmission can achieve better transmission effects, but the roller chain occupies a large proportion in the width direction of the crawler track, which reduces the effective conveying area of ​​the crawler track and is not conducive to energy saving and consumption reduction.

[0003] To solve the above problems, there is a utility model patent with the existing announcement number CN203473868U, which discloses a crawler chain feeder. The disclosed scheme proposes the use of teeth and sprocket meshing, that is, a tooth is designed under the armor plate for transmission, without the need for a roller chain.

[0004] Although the crawler chain feeder disclosed in the utility model solves the problem of the roller chain occupying the crawler width, it fails to solve the problem of the crawler deviation; the crawler will gradually deviate to one side during actual use until the teeth and sprocket are disengaged, making the transmission impossible. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a crawler conveyor for a feeder, which can limit and correct the conveying direction of the crawler conveyor during the conveying process, and will not have problems such as deviation and tooth disengagement. It has a simple structure, is easy to process, install and maintain, has a long service life, and has good practicality.

[0006] The utility model solves the technical problem by adopting the following technical solution: a crawler conveyor for a feeder, comprising a sprocket and a crawler, wherein the crawler comprises toothed armor plates and common armor plates, wherein the toothed armor plates are arranged in at least two rows along the length direction of the crawler, and the bottom of the toothed armor plates is fixed with a first transmission tooth and a second transmission tooth;

[0007] The sprocket includes a first sprocket plate, a sprocket spacer and a second sprocket plate, and the first sprocket plate and the second sprocket plate are arranged on both sides of the sprocket spacer; when in use, the first transmission tooth of the toothed armor plate is engaged with the first sprocket plate, and the second transmission tooth is engaged with the second sprocket plate, and the sprocket spacer is located between the first transmission tooth and the second transmission tooth.

[0008] Furthermore, a plurality of connecting bolts are provided on the sprocket, and the first sprocket tooth plate and the second sprocket tooth plate are coaxially fixed with the sprocket spacer through the connecting bolts.

[0009] Furthermore, the sprocket spacer is disc-shaped, the first sprocket tooth plate and the second sprocket tooth plate have the same structure, and the diameter of the sprocket spacer is greater than or equal to the pitch circle diameter of the first sprocket tooth plate and smaller than the tooth top circle diameter of the first sprocket tooth plate.

[0010] Beneficial effects of the utility model:

[0011] The utility model discloses a crawler conveyor for a feeder, wherein the crawler is composed of a toothed armor plate and an ordinary armor plate, wherein the first transmission tooth and the second transmission tooth on the toothed armor plate are meshed with the first sprocket tooth plate and the second sprocket tooth plate of the sprocket, and the sprocket spacer is located between the first transmission tooth and the second transmission tooth, thereby limiting the left and right deviation of the toothed armor plate, thereby effectively improving the problem of crawler operation deviation, and the utility model has a simple structure, low processing cost, convenient installation and maintenance, and good practicality.

[0020] The utility model is further described in detail below with reference to the accompanying drawings.

[0021] The utility model discloses a crawler conveyor for a feeder.

[0022] Reference Figures 1 to 5 A crawler conveyor for a feeder includes a sprocket 2 and a crawler 1. Two sprockets 2 are provided. One of the two sprockets 2 can be used as a driving wheel and the other as a driven wheel, or both can be used as driving wheels. The crawler 1 includes a plurality of toothed armor plates 11 and common armor plates 12. The plurality of toothed armor plates 11 are arranged in at least two rows along the length direction of the crawler 1. The bottom of the toothed armor plates 11 is integrally formed with a first transmission tooth 111 and a second transmission tooth 112.

[0023] Reference Figures 4 to 7 The sprocket 2 includes a first sprocket plate 21, a sprocket spacer 23 and a second sprocket plate 22. The sprocket spacer 23 is disc-shaped. The first sprocket plate 2 and the second sprocket plate 22 have the same structure and are symmetrically arranged on both sides of the sprocket spacer 23. A plurality of connecting bolts 24 are passed through the sprocket 2. The first sprocket plate 21 and the second sprocket plate 22 are coaxially fixed to the sprocket spacer 23 by the connecting bolts 24.

[0024] When in use, the first transmission tooth 111 of the toothed armor plate 11 is meshed with the first sprocket 21, the second transmission tooth 112 is meshed with the second sprocket 22, and the sprocket spacer 23 is located between the first transmission tooth 111 and the second transmission tooth 112, thereby preventing the toothed armor plate 11 from moving left and right, that is, preventing the track chain 1 from deviating.

[0025] The diameter of the sprocket spacer 23 is greater than or equal to the pitch circle diameter of the first sprocket tooth plate 21, and smaller than the tooth top circle diameter of the first sprocket tooth plate 21, so that the edge of the sprocket spacer 23 can fully contact the tooth surface of the first transmission tooth 111 and the second transmission tooth 112, thereby ensuring the limiting effect of the sprocket spacer 23 on the transmission of the crawler track 1.

[0026] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
