Hold with 26 top relative position of third slide bar, and connecting rod 29 can move up and down, when connecting rod 29 moves up and down, connecting rod 29
Third slide bar 26 can be driven to move up and down, third slide bar 26 passes through third sliding sleeve 27 that cylinder 25 is driven to move up and down, and passes through limit
Bar 28, sliding block 24 and sliding slot 23 can make cylinder 25 more steadily move up and down, and when cylinder 25 moves up and down, can drive
The output rod of cylinder 25 moves up and down, and to drive stripper plate 16 to move up and down, the nose cone 21 of 16 bottom of stripper plate is continuous
Extruding and broken soil so that the soil of bulk is broken down into the soil of fritter, when stripper plate 16 moves up and down, stripper plate 16
Top under the promotion of cylinder 25, will be by from the downward impact force of cylinder 25, when squeezing when stripper plate 16 moves up
When pressing plate 16 moves down, in conjunction with the impact force of cylinder 25, the stronger Ground shock waves of the meeting of stripper plate 16 are impacted in earth surfaces
Distance is shorter, reduces the frequency of entire body vibrations, extends the service life of body, by being crushed to bulk soil,
It facilitates staff and takes out pollutant therein, then transport again, improve the treatment effeciency of pollution soil.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
