Secondary oil cylinder of wood splitting machine

Abstract

The invention discloses a secondary oil cylinder of a wood splitting machine, which comprises a cylinder barrel, a cylinder base plate, a primary guiding sleeve, a primary piston, a primary piston rod, a secondary guiding sleeve, a secondary piston and a secondary piston rod. The primary piston is arranged in the cylinder barrel, the primary guiding sleeve is mounted at the top end of the cylinder barrel, the primary piston rod comprises an inner barrel and an outer barrel, bottom ends of the inner barrel and the outer barrel are respectively fixedly connected with the primary piston, the outer barrel penetrates through the primary guiding sleeve, the secondary piston is disposed in the inner barrel, the bottom end of the secondary piston rod is connected with the secondary piston, the secondary guiding sleeve is mounted inside the top end of the inner barrel, the secondary piston rod penetrates through the secondary guiding sleeve, the top end and the bottom end of the cylinder barrel are respectively provided with a first oil inlet and a second oil inlet, a first oil channel is arranged between the cylinder barrel and the outer barrel, a second oil channel is arranged between the inner barrel and the outer barrel, an external oil inlet is arranged at the bottom end of the outer barrel, an internal oil inlet is arranged at the top end of the inner barrel, a third oil channel is arranged between the secondary piston rod and the inner barrel, and the first oil inlet is successively communicated with the first oil channel, the external oil inlet, the second oil channel, the internal oil inlet and the third oil channel.

Description

technical field [0001] The invention relates to an oil cylinder of a wood splitter, in particular to a secondary oil cylinder of a wood splitter. Background technique [0002] In foreign countries, due to the lack of coal resources and environmental protection restrictions, most of the winter heating is made of wood. Therefore, a simple device such as a log splitter was born, which is equivalent to the ax used in Chinese households. The more compact the device is, the more practical it is, and the lighter it is, the more marketable it is when it achieves the same performance. For the wood splitter, if the structure is compact and light, it mainly depends on the external dimensions of the oil cylinder, that is, the installation distance of the oil cylinder. To achieve the same stroke, the same pressure, the smaller the installation distance, the more compact and lighter the shape of the entire log splitter. But present log splitter oil cylinder profile and installation dist...

AI Technical Summary

Problems solved by technology

However, the shape and installation distance of the current log splitter oil cylinder are relatively large. In view of the above situation, the secondary oil cylinder of the log splitter has been developed.
