Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, and particularly relates to an intermediate casing of a scraper conveyor. Background Art

[0002] A scraper conveyor is a continuous conveying device for conveying powdery, small-particle and small-block shaped bulk materials, and can convey horizontally, obliquely or vertically. During conveying, the scraper chain is completely buried in the material, so it is also called an enclosed scraper conveyor.

[0003] The scraper conveyor includes: a head, a tail, an intermediate casing, a transmission chain, a scraper and a driving mechanism. Among them, the intermediate casing is installed between the head and the tail, and the driving mechanism is installed on the head for driving two transmission chains to perform a closed-loop movement in the intermediate casing. The scraper is fixed between the two transmission chains and thus moves in the intermediate mechanism following the transmission chains, thereby completing the continuous conveying of materials.

[0004] After long-term use, the transmission chain may break at a certain place in the intermediate casing. At this time, it is necessary to repair the transmission chain. However, since the existing intermediate casing is composed of several sections and each single section is an integral structure, it cannot be partially disassembled. Therefore, it is impossible to carry out repairs at the break position of the transmission chain, resulting in complex operation, time-consuming and laborious repair of the transmission chain, and low repair efficiency, leading to poor actual use effect of the equipment. Summary of the Utility Model

The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and thus are only examples and cannot be used to limit the protection scope of the present utility model.

[0069] First of all, it should be noted that some orientation terms involved in the following description to clearly illustrate the technical solution of the present utility model, such as "top surface", "bottom surface", etc., are all the meanings analogously obtained according to the normal orientations of the components in the middle housing of the scraper conveyor, and are only for the convenience of describing the present utility model 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, and thus cannot be understood as a limitation to the present utility model.

[0070] In addition, the terms "first" and "second" are only used for the purpose of description and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0072] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0073] Embodiment:

[0074] As Figure 1 shown, the embodiment of the present application discloses an intermediate housing of a scraper conveyor, which is installed between the head and the tail and serves as a conveying channel for materials. The specific structure includes: a plurality of feeding sections 1 and a plurality of conveying sections 2 that are detachably butted end to end in sequence.

[0075] Exemplarily, this embodiment specifically has two feeding sections 1 and five conveying sections 2, but it is not limited thereto. There can be fewer or more, and adjustments can be made according to actual application situations without specific limitations.

[0076] Specifically, as Figure 2 and Figure 3 shown, the feeding section 1 includes:

[0077] An upper feeding trough body 11 with a first upper trough channel 11a inside;

[0078] A lower feeding trough body 12 with a first lower trough channel 12a inside;

[0079] A feeding hopper 13 installed on the top surface of the upper feeding trough body 11 and communicating with the first upper trough channel 11a. It has a diversion cavity with an isosceles trapezoidal cross-section inside, which is used to guide the convergence of materials and improve the conveying effect;

[0080] Two clamping plates 14 are respectively clamped between the butting surfaces on both sides of the upper feeding trough body 11 and the lower feeding trough body 12, and extend inwards between the first upper trough channel 11a and the first lower trough channel 12a, and are used to support the transmission chain located in the first upper trough channel 11a;

[0081] Among them, the upper feeding trough body 11 and the lower feeding trough body 12 are detachably connected, and the cross-sections of the first upper trough channel 11a and the first lower trough channel 12a are both of convex structures and are symmetrically arranged up and down with respect to the clamping plate 14.

[0082] It should be noted that as Figure 7As shown, the clamping plate 14 does not separate the first upper channel 11a and the first lower channel 12a. Therefore, after the material is put into the top of the feed hopper 13, it will pass through the first upper channel 11a and then fall into the first lower channel 12a. Finally, it is pushed by the scraper in the first lower channel 12a and moves towards the discharge port.

[0083] Specifically, as Figure 4 and Figure 5 shown, the conveying section 2 includes:

[0084] an upper conveying trough body 21 with a second upper channel 21a inside,

[0085] a lower conveying trough body 22 with a second lower channel 22a inside,

[0086] a partition plate 23 arranged between the upper conveying trough body 21 and the lower conveying trough body 22 and separating the second upper channel 21a and the second lower channel 22a,

[0087] wherein, the upper conveying trough body 21 and the lower conveying trough body 22 are detachably connected, the second upper channel 21a matches the first upper channel 11a, and the second lower channel 22a matches the first lower channel 12a.

[0088] It should be noted that, as Figure 8 shown, the partition plate 23 separates the second upper channel 21a and the second lower channel 22a, so as to ensure that the material is only conveyed in the second lower channel 22a, and thus it will not slide into the second upper channel 21a due to the upward slope when being conveyed in conveyors such as inclined type, vertical type or Z type, thereby fully guaranteeing the conveying effect and improving the conveying stability.

[0089] It should be noted that, as Figure 7 and Figure 8 shown, the cross-sections of the first upper channel 11a, the first lower channel 12a, the second upper channel 21a and the second lower channel 22a are all in a convex structure and have the same size. The middle area is for the movement of the scraper, and the two side areas are for the movement of the transmission chain.

[0090] It can be understood that the first upper channels 11a of several feeding sections 1 and the second upper channels 21a of several conveying sections 2 are connected end to end in sequence to form a complete upper channel. The transmission chain and the scraper in this upper channel always perform return movement; the first lower channels 12a of several feeding sections 1 and the second lower channels 22a of several conveying sections 2 are connected end to end in sequence to form a complete lower channel. The transmission chain and the scraper in this lower channel always perform forward movement, so as to push the material forward towards the discharge port.

[0091] In the above technical solutions, any one of the upper feeding trough 11, the lower feeding trough 12, the upper conveying trough 21 or the lower conveying trough 22 can be individually disassembled, and the disassembly will not cause the intermediate housing to fall apart. Therefore, when the drive chain breaks at a certain place in the intermediate housing, as long as the trough corresponding to that place is removed, the faulty area of the transmission chain can be exposed to the outside, facilitating maintenance. The operation is simple, time-saving, labor-saving, highly efficient, and has good actual use effects.

[0092] In some embodiments, such as Figure 2 and Figure 3 shown, the upper feeding trough 11 includes:

[0094] Two L-shaped plates 112 are respectively arranged at the inner two-side corners of the first upper shell plate 111, used to form the first upper trough 11a, and improve the structural strength of the top surface of the first upper shell plate 111, thereby ensuring the structural stability;

[0101] Among them, a clamping plate 14 is clamped between an adjacent first upward flanging 113 and a first downward flanging 122, and the three are detachably connected by a set of bolt assemblies arranged at intervals along the axial direction.

[0102] Through the above settings, the connection stability is improved, the disassembly and assembly portability is enhanced, and the contact area is increased, thereby enhancing the sealing performance and the clamping stability of the clamping plate 14.

[0103] On the basis of the above embodiment, as Figure 2 and Figure 3 shown, the feeding section 1 further includes: two first upper wear-resistant plates 15, two first lower wear-resistant plates 16, two first upper reinforcing plates 17, two first lower reinforcing plates 18 and four first sealing strips 19.

[0105] The two first lower wear-resistant plates 16 are respectively arranged on both sides of the bottom surface of the first lower channel 12a, and have very high wear resistance and good impact resistance, and are used to support the two transmission chains in the first lower channel 12a, extending the service life of the casing.

[0106] The two first upper reinforcing plates 17 are in an L-shaped structure, and are respectively arranged at the outer two corners of the first upper shell plate 111, and both ends are respectively connected to the two first upper flanges 114. They are fully fitted and fixed with the outer corners of the first upper shell plate 111, thereby improving the structural strength of this area, reducing stress concentration, preventing structural deformation, and improving structural rigidity.

Their shape and size are consistent with the first upward flanging 113 and the first downward flanging 122, improving the sealing performance and ensuring the conveying effect.

[0109] On the basis of the above embodiment, as Figure 4 and Figure 5 shown, the upper conveying trough body 21 includes:

It is preferably a bent plate, which is convenient for production and manufacturing, and can be directly bent to form the second lower channel 22a, which is convenient for production and manufacturing, has a simple and compact structure, small material consumption, and reduces production costs;

[0115] Two second lower flanges 222 are respectively arranged on both sides of the top edge of the second lower shell plate 221. It is preferably integrally formed with the second lower shell plate 221, so as to facilitate production and manufacturing, reduce the manufacturing difficulty, and improve production efficiency;

[0116] Two second lower flanges 223 are respectively sleeved on the outer ends of both sides of the second lower shell plate 221, and the top parts of both sides are respectively connected to the two second lower flanges 222.

[0117] Wherein, both sides of the partition plate 23 are respectively clamped by the adjacent second upper flanges 212 and second lower flanges 222, and are respectively detachably connected by a set of bolt assemblies arranged at intervals in the axial direction.

[0118] Through the above settings, the connection stability is improved, the disassembly and assembly portability is enhanced, and the contact area is increased, thereby enhancing the sealing performance and the clamping stability of the partition plate 23.

[0119] On the basis of the above embodiment, as Figure 4 and Figure 5 shown, the conveying section 2 further includes: two second upper wear-resistant plates 24, two second lower wear-resistant plates 25, two second upper reinforcing plates 26, two second lower reinforcing plates 27 and four second sealing strips 28.

[0120] Two second upper wear-resistant plates 24 are respectively arranged on both sides of the top surface of the partition plate 23. They have very high wear resistance and good impact resistance, and are used to support the two drive chains in the second upper channel 21a, extending the service life of the casing.

[0121] Two second lower wear-resistant plates 25 are respectively arranged on both sides of the bottom surface of the second lower channel 22a. They have very high wear resistance and good impact resistance, and are used to support the two drive chains in the second lower channel 22a, extending the service life of the casing.

[0122] Two second upper reinforcing plates 26 are in an L-shaped structure and are respectively arranged at the outer corners on both sides of the second upper shell plate 211, and both ends are respectively connected to the two second upper flanges 213. They are fully fitted and fixed with the outer corners of the second upper shell plate 211, thereby improving the structural strength of this area, reducing stress concentration, preventing structural deformation, and improving structural rigidity.

[0123] Two second lower reinforcing plates 27 are in an L-shaped structure and are respectively arranged at the outer corners on both sides of the second lower shell plate 221, and both ends are respectively connected to the two second lower flanges 223. They are fully fitted and fixed with the outer corners of the second lower shell plate 221, thereby improving the structural strength of this area, reducing stress concentration, preventing structural deformation, and improving structural rigidity.

[0124] Four second sealing strips 28 are respectively arranged on both sides of the top surface and both sides of the bottom surface of the partition plate 23, and are located between the adjacent second upper flanges 212 and second lower flanges 222. Their shape and size are consistent with those of the second upper flanges 212 and second lower flanges 222, improving the sealing performance and ensuring the conveying effect.

[0125] On the basis of the above embodiments, as Figure 7 and Figure 8 shown, the first upper flange 114 and the first lower flange 123 can be combined into the first flange ring 1a, the second upper flange 213 and the second lower flange 223 can be combined into the second flange ring 2a, and the first flange ring 1a and the second flange ring 2a are adapted to each other.

[0126] Specifically, both the first flange ring 1a and the second flange ring 2a are in a rectangular structure, and a plurality of mutually corresponding mounting holes are provided on the periphery, which are used for bolt connection, thereby realizing the detachable docking between the feeding section 1 and the feeding section 1, between the conveying section 2 and the conveying section 2, and between the feeding section 1 and the conveying section 2.

[0127] Preferably, a sealing ring is further provided between the sections, and the shape and size of the sealing ring are adapted to those of the first flange ring 1a and the second flange ring 2a, which is used to improve the sealing performance and ensure the conveying effect.

[0129] In some embodiments, the feeding section 1 is linear, and the conveying section 2 is linear or arc-shaped.

[0130] Specifically, the conveying section 2 includes standard sections and non-standard sections. Among them, the standard sections are linear, and the non-standard sections are arc-shaped.
