[0003] The technical problem to be solved by the utility model is to provide a detachable impact bed, which is convenient for replacing wearing parts and easy for maintenance.

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A detachable buffer bed comprises: a buffer bed and a buffer roller group, the buffer bed comprises a buffer bed crossbeam, a longitudinal beam and a buffer bar, the buffer roller group comprises a buffer roller group crossbeam and a buffer roller, a support frame is detachably mounted between the longitudinal beam and the buffer bed crossbeam, a roller bracket is detachably mounted between the buffer roller and the buffer roller group crossbeam, the support frame and the roller bracket both comprise a base plate at the bottom, and a rolling guide structure is respectively provided between the base plate and the buffer bed crossbeam and the buffer roller group crossbeam.

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as limiting the scope of protection of the present invention.

[0023] In the description of this specification, it should be understood that the descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] In this specification, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features indicated. Unless otherwise expressly specified, terms such as "disposed," "installed," and "connected" should be interpreted broadly. Persons skilled in the art can reasonably determine the specific meanings of these terms in this utility model based on the specific content of the technical solution.

[0025] like Figure 1 As shown, a detachable buffer bed includes: a buffer bed 1 and a buffer roller assembly 2. Both the buffer bed 1 and the buffer roller assembly 2 have a V-shaped structure. The buffer bed 1 includes a buffer bed crossbeam 11, longitudinal beams (15a, 15b), and buffer bars 16. The buffer roller assembly 2 includes a buffer roller assembly crossbeam 21 and buffer rollers 24. A support frame 12 is detachably mounted between the longitudinal beams (15a, 15b) and the buffer bed crossbeam 11. An idler bracket 22 is detachably mounted between the buffer roller 24 and the buffer roller assembly crossbeam 21. The buffer bed 1 and the buffer roller assembly 2 are structurally strong and reliable.

[0026] When replacing the buffer strip 16 or the buffer roller 24, remove the fasteners between the support frame 12 or the roller bracket 22 and the buffer bed 1 or other structures of the buffer roller group 2. At this time, the support frame 12 and the roller bracket 22 and the buffer strip 16 and buffer roller 24 fixed thereon can be taken out from the outside. Remove the fasteners between the support frame 12 and the longitudinal beam 15b, between the longitudinal beam (15a, 15b) and the buffer strip 16, and between the roller bracket 22 and the buffer roller 24, such as various bolts, and replace the wearing parts, namely the buffer strip 16 and buffer roller 24.

[0027] Both the support frame 12 and the roller bracket 22 include a base plate at the bottom. The base plate of the support frame 12 is defined as the first base plate 14, and the base plate of the roller bracket 22 is defined as the second base plate 23. Rolling guide structures are provided between the first base plate 14 and the impact bed crossbeam 11, and between the second base plate 23 and the impact bed roller assembly crossbeam 21. This reduces friction between the support frame and the roller bracket and their respective crossbeams, making them easier to remove and maintain. The outer side here refers to the direction of the ends of the impact bed crossbeam 11.

[0028] Specifically, such as Figure 2 and Figure 4 As shown, the rolling guide structure includes an extension plate 32 positioned below the first and second base plates 14, 23, and a guide rail 31 positioned on the sides of the impact bed beam 11 and the impact roller assembly beam 21. A cam follower bearing 33 is mounted on the extension plate 32 and is in rolling connection with the guide rail 31. The guide rail 31 extends laterally to the ends of the impact bed beam 11 and the impact roller assembly beam 21. The tail end of the guide rail 31 is open. When the cam follower bearing 33 rolls to the tail end of the guide rail 31, it disengages from the impact bed beam 11 or the impact roller assembly beam 21. Once the cam follower bearing 33 is attached to the guide rail 31, the friction between the support frame 12 or the impact roller frame 22 and the beam is significantly reduced, simplifying maintenance.

[0029] like Figure 2 and Figure 3 As shown, when the first base plate 14 is secured to the impact bed crossbeam 11 or the second base plate 23 is secured to the impact roller assembly crossbeam 21, the upper surface of the guide rail 31 is higher than the lower surface of the cam follower bearing 33. This represents the operating state of the impact bed 1. The support frame 12 and the roller bracket 22 are in full contact with the impact bed crossbeam 11 and the impact roller assembly crossbeam 21, respectively. The impact of the material is borne entirely by the impact bed crossbeam 11 and the impact roller assembly crossbeam 21, while the cam follower bearing 33 is not impacted.

[0030] Figure 4 and Figure 5The buffer bed 1 is in the maintenance state. At this time, the belt conveyor stops running and is in an unloaded state. The cam follower bearing 33 is dragged onto the guide rail 31 along with the support frame 12 and the roller bracket 22. The support frame 12 and the roller bracket 22 are raised to form a gap between the buffer bed beam 11 and the buffer roller group beam 21. The contact between the support frame 12 and the buffer bed beam 11 and the roller bracket 22 and the buffer roller group beam 21 is reduced, and the cam follower bearing 33 is used for support instead. Therefore, the friction force becomes smaller, so that the support frame 12 and the buffer strip 16 fixed thereon, as well as the roller bracket 22 and the buffer roller 24 fixed thereon can be easily dragged out, making it easy to maintain.

[0031] In a further preferred embodiment, the edge of the guide rail 31 near the cam follower bearing 33 is configured as a gradually ascending slope, facilitating the cam follower bearing 33 to be dragged onto the guide rail 31. A reinforcement structure is also provided between the extension plate 32 and the impact bed crossbeam 11 and the impact roller assembly crossbeam 21 to enhance the strength of the guide rail 31 and extend its service life.

[0032] To ensure stable movement of the support frame 12 and roller bracket 22, two rolling guide structures are installed on the underside of the base plates of the support frame 12 and roller bracket 22. These rolling guide structures are located on the front and rear sides of the impact bed crossbeam 11 and the impact roller assembly crossbeam 21, respectively. The front and rear directions represent the direction of belt movement, which is consistent with the extension direction of the longitudinal beams (15a, 15b). The extension plate 32 is equipped with two cam follower bearings 33, located at each end of the extension plate 32, with their lower surfaces at the same height.

[0033] like Figure 1 、 Figure 2 and Figure 4 As shown, the support frame 12 also includes a fixing plate 13 that is obliquely mounted above the first base plate 14. A central longitudinal beam 15a is mounted to the first base plate 14 via fasteners, while a lateral longitudinal beam 15b is mounted to the fixing plate 13 via fasteners. In this application, the central longitudinal beam 15a is divided into two parts, one fixed to each side of the first base plate 14. An unequal distribution method can also be used as needed. The central longitudinal beam 15a is mounted to the inner end of the first base plate 14, while the outer end of the first base plate 14 is secured to the impact bed cross beam 11 via fasteners. Here, the outer side refers to the two ends of the impact bed cross beam 11, and the inner side refers to the middle of the impact bed cross beam 11. The fasteners can specifically be bolts.

[0034] The detachable buffer bed of the utility model has a support frame detachably installed between the longitudinal beam and the buffer bed cross beam of the buffer bed, and a roller bracket detachably installed between the buffer roller and the cross beam of the buffer roller group. The wearing parts, namely the buffer strip and the buffer roller, can be replaced by disassembling the support frame and the roller bracket. The bottom plates of the support frame and the roller bracket are respectively provided with rolling guide structures on the basis of the buffer bed cross beam and the cross beam of the buffer roller group, which can reduce the friction between the support frame and the roller bracket and their cross beams, and are easy to drag out and easy to repair.

The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention and without any creative work, and such changes and modifications shall fall within the scope of protection of the present invention.
