[0005] Preferably, the connecting tube is sleeved on the outside of the shaft column, and the outer wall of the shaft column is interlaced and connected with the protective cover.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] In the utility model, the connection tube and the adding tube are provided to protect and lubricate the connection between the shaft column and the scraper, so that the movement can be carried out flexibly and the flexibility can be prevented from being contaminated by dust.

[0008] In the utility model, the sealing ring is provided to seal the connection between the connecting tube and the protective cover.

[0009] In the utility model, the provision of the additional protective cover further protects and seals the connection between the shaft column and the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings:

[0016] Example:

[0017] As attached Figure 1 As shown, a new type of shovel loader swing frame includes a side assembly seat 1, and a splicing seat 2 is welded on the left and right sides of the lower part of the side assembly seat 1; a connecting plate 3 is welded on the left and right sides of the upper part of the side assembly seat 1; a shaft column 4 is welded on the middle part of the outer wall of the side assembly seat 1; a movable connecting cover structure 6 is installed on the outer side of the shaft column 4; and a buffer bottom sleeve structure 5 is installed on the bottom of the side assembly seat 1.

[0018] As attached Figure 2 As shown, in the above embodiment, specifically, the movable connecting cover structure 6 includes a connecting tube 61, and the right side of the inside of the connecting tube 61 is threadedly connected with an adding tube 62; a protective cover 64 is arranged on the left side of the connecting tube 61; a sealing ring 63 is glued to the left end of the connecting tube 61 and the right end of the protective cover 64; the connecting tube 61 is installed with the end bolts on the outer side of the shaft column 4, and the connecting tube 61 cooperates with the sealing ring 63 to fit tightly against the connected scraper loader. After the initial connection, the protective cover 64 is again made to fit tightly against the connected scraper loader and is bolted and fixed to the shaft column 4.

[0019] As attached Figure 3 As shown, in the above embodiment, specifically, the buffer bottom sleeve structure 5 includes a bottom sleeve 51, and a sealing gasket 52 is glued to the middle part of the upper inner wall of the bottom sleeve 51; assembly plates 53 are bolted to the left and right sides of the upper inner part of the bottom sleeve 51; a compression spring 55 is installed at the lower end of the assembly plate 53; a support plate 54 is bolted to the lower end of the compression spring 55; the outer side of the support plate 54 is glued to the bottom sleeve 51; when the top of the side assembly seat 1 is bumped, it contacts the bottom sleeve 51 and cooperates with the compression spring 55 on the upper side of the support plate 54 to perform buffering and decompression.

[0020] In the above embodiment, specifically, a rubber ring seal is embedded in the connection between the protective cover 64 and the shaft column 4.

[0021] In the above embodiment, specifically, the adding cylinder 62 is supported by the connecting cylinder 61 and is matched with the shaft column 4, and the lubricant is added to increase the flexibility of the movable part.

[0022] In the above embodiment, specifically, the bottom protective sleeve 51 is made of a rubber sleeve and is glued to the lower end of the side assembly seat 1 , and the assembly plate 53 on the inner wall of the bottom protective sleeve 51 is bolted to the lower end of the side assembly seat 1 .

[0023] In the above embodiment, specifically, the compression spring 55 is supported between the assembly plate 53 and the support plate 54, and when the side assembly seat 1 is hit, it is pre-contacted to perform buffering and decompression protection.

[0024] How it works

[0025] The working principle of the utility model is as follows: when installed on a scraper for use, the outer side of the side assembly seat 1 is movably installed on the scraper through the shaft column 4, and the frame is connected to the surface of the connecting plate 3 to complete the assembly. After the initial installation, the connecting tube 61 is installed with the end bolts on the outer side of the shaft column 4, and the connecting tube 61 cooperates with the sealing ring 63 to fit tightly against the connected scraper. After the initial connection, the protective cover 64 is again made to fit tightly against the connected scraper and is fixed with the shaft column 4 bolts. Finally, the adding tube 62 with lubricating liquid is transferred to the connecting tube 61 for lubrication. During use, when the top of the side assembly seat 1 is bumped, it contacts the bottom sleeve 51 and cooperates with the compression spring 55 on the upper side of the support plate 54 for buffering and decompression protection.
