Detailed Description of the Specific Embodiments

[0018] In order to solve the problems in the background art, the rivet and tenon connection structure of the tipping plate base for the hydraulic rear tipping machine of the present application is specifically invented, which has good integrity and more stable structure.

[0019] The following will describe in detail the specific embodiments of the present invention with reference to the drawings. It should be noted that in the description of the present invention, the orientation or positional relationship indicated by terms such as "upper end", "lower end", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and 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, and therefore should not be construed as a limitation to the present invention.

[0020] A hydraulic rear tipping vehicle includes a tipping plate 1 and a base 2. The left and right sides at the ends of the tipping plate and the base are connected by a tipping plate base riveting and tenoning connection structure 3 for the hydraulic rear tipping vehicle of the present application.

[0021] The tipping plate base riveting and tenoning connection structure 3 for the hydraulic rear tipping vehicle of the present application includes two vertical plates 31, a pin shaft 32, a pin shaft plate 33, a support plate 34, a tipping plate 1 and a base 2. Pin holes are opened at the upper ends of the two vertical plates 31. The end of the tipping plate 1 is two connecting plates 11, and a connecting sleeve 12 is between the two connecting plates 11. The pin shaft 32 passes through the holes at the upper ends of the two vertical plates 31 and the connecting sleeve 12 between the two connecting plates 11. A bush is between the connecting sleeve 12 and the pin shaft 32. A pin shaft plate 33 is fixed at one end of the pin shaft 32. A cross beam 21 is provided at the end of the base 2 connected to the tipping plate 1. The cross beam 21 passes through the two vertical plates 31 and is welded to the vertical plates. One end of the support plate 34 is welded to the cross beam 21, and the other end passes through the two vertical plates 31 and is welded to the two vertical plates. The connection method between the tipping plate and the base of the present application has a compact structure, high strength, convenient processing, good technological property, high precision, high wear resistance and high bearing capacity.

[0022] One end of the support plate 34 connected to the cross beam 21 is also welded to the vertical plate at the same time. The other end of the support plate is rectangular, passes through the two vertical plates 31 and is welded to the vertical plates. The support plate better connects the vertical plates and the cross beam, and has high stability.

[0023] Pin holes 311 for the pin shaft to pass through are opened at the upper ends of the vertical plates 31. Support plate holes 312 for the support plate to pass through are opened in the middle of the vertical plates. Cross beam holes 313 for the cross beam to pass through are opened at the lower ends of the vertical plates.

[0024] The support plate and the two vertical plates of the present application form a riveting and tenoning structure, and the two cross beams of the base and the two vertical plates also form a riveting and tenoning structure. This riveting and tenoning structure can increase strength, enhance rigidity, and has good integrity of the structure. The riveting and tenoning structure has a simple process, a compact structure, saves time and effort, has a large structural strength, good wear resistance and high bearing capacity. Its performance in use is far higher than the simple pin shaft connection structure in the prior art.

[0025] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and without departing from the content of the technical solution of the present invention, and design similar structural manners and implementations to this technical solution without creative work based on the technical essence of the present invention, they should all fall within the protection scope of the present invention.
