Relative to prior art, silt cleaning plant in underground of the present invention has the advantage that：
When the underground silt cleaning plant provided using the present invention, first, underground silt cleaning plant is transferred vertically
To shaft bottom, then, driver is opened, driver driving rotary shaft rotation, rotary shaft drives screw blade rotation so that inner cylinder
Middle generation negative pressure, therefore outside silt is from the sand inlet of baffle plate and the charging aperture of inner cylinder enter inner cylinder, and with along rotation
Axle and screw blade are moved upwards, and during being moved upwards in silt inner cylinder, silt can be via more on the wall of inner cylinder side
Individual sand outlet enters the space between outer barrel and inner cylinder, is stopped the rotation into the silt between outer barrel and inner cylinder and moves and fall on gear
On plate, baffle plate can prevent silt from dropping back into again in well.After silt is filled in space in the middle of inner cylinder and outer barrel, finally, by underground
Silt cleaning plant is promoted to ground, so as to which the silt of underground is taken out of.Above-mentioned scale removal process is repeated several times, you can by well
Under silt clean out, reduce well is scrapped caused by Sediment Siltation quantity.
Further, since being provided with training for sediment pipe on the inner cylinder of above-mentioned underground silt cleaning plant, one end of training for sediment pipe is connected with
Self-styled flexible pipe, therefore, after opening driver, silt from inner cylinder, via training for sediment pipe and self-styled flexible pipe enter inner cylinder and
Region between outer barrel, when entering, the silt in inner cylinder and outer barrel is more and more, little by little, the mud between inner cylinder and outer barrel
Sand will cover self-styled flexible pipe, so as to the opening of self-styled flexible pipe be pushed down, so as to close the self-styled flexible pipe.It is so designed that, in Jiang Jing
During lower silt cleaning plant is lifted away from well, the silt between inner cylinder and outer barrel will not turn again to interior
In cylinder, it would not also be dropped out again from the charging aperture of inner cylinder.So as to add the quantity of sand and mud once cleaned out, and then improve cleaning
The efficiency of silt.
In summary, the lightweight of the underground silt cleaning plant provided of the invention, silt cleaning efficiency are high, repeatable many
It is secondary use and service life is longer.

The structural representation of baffle plate 4 in the underground silt cleaning plant of offer；Fig. 3 clears up for underground silt provided in an embodiment of the present invention
The structural representation of rotary shaft 3 in device；As Figure 1-3, silt cleaning plant in underground provided in an embodiment of the present invention, bag
Include：Inner cylinder 2 is provided with outer barrel 1, outer barrel 1, the bottom of outer barrel 1 is provided with baffle plate 4, and baffle plate 4 is connected with outer barrel 1, is set on baffle plate 4
Sand inlet 5 is equipped with, the diameter of sand inlet 5 is less than or equal to the diameter of inner cylinder 2, and is connected with the charging aperture 6 of the bottom of inner cylinder 2
Logical, the side of inner cylinder 2, which is provided with multiple sand outlets, inner cylinder 2, is provided with rotary shaft 3, and the side of rotary shaft 3 is provided with spirally
Blade 7, one end of rotary shaft 3 is connected with driver, and driver driving rotary shaft 3 is rotated.
When using silt cleaning plant in underground provided in an embodiment of the present invention, first, underground silt cleaning plant is erected
Shaft bottom directly is transferred to, then, driver is opened, driver driving rotary shaft 3 rotates, and rotary shaft 3 drives screw blade 7 to revolve
Turn so that negative pressure is produced in inner cylinder 2, therefore outside silt enters inner cylinder from the sand inlet 5 of baffle plate 4 and the charging aperture 6 of inner cylinder 2
In 2, and moved upwards with along rotary shaft 3 and screw blade 7, during being moved upwards in silt inner cylinder 2, silt meeting
Enter the space between outer barrel 1 and inner cylinder 2 via multiple sand outlets on the side wall of inner cylinder 2, between outer barrel 1 and inner cylinder 2
Silt, which stops the rotation, to be moved and falls on baffle plate 4, and baffle plate 4 can prevent silt from dropping back into again in well.In the middle of inner cylinder 2 and outer barrel 1
Space fill after silt, finally, underground silt cleaning plant is promoted to ground, so as to which the silt of underground is taken out of.
Above-mentioned scale removal process is repeated several times, you can clean out the silt of underground, reduces what the well caused by Sediment Siltation was scrapped
Quantity.During driving screw blade 7 to rotate in rotary shaft 3, silt is to mix well water to enter inner cylinder 2 together
In, therefore, using above-mentioned underground silt cleaning plant, it is small to sposh fine sand face, big brick to 3.5 centimeters or so of diameter or
Cobble etc. all can be together entered in inner cylinder 2 with well water, therefore, and the use scope of above-mentioned underground silt cleaning plant is wider.
It should be noted that the efficiency in order to improve cleaning silt, underground silt cleaning plant is connected with lifting device, by
Underground silt cleaning plant is transferred to underground by lifting device, and the underground silt cleaning plant for having filled silt is carried from well
Emersion comes, and lifting means can be hoist engine, chain block, electric block, trepan, crane or agricultural vehicle etc..Driving rotation
The driver of rotating shaft 3 can be water logging motor, and water logging motor has the advantages that waterproof, burn-out-proof, square silt.
In order to further improve the efficiency that above-mentioned underground silt cleaning plant clears up silt, rotary shaft 3 is driven in driver
While being walked around with screw blade 7, underground silt cleaning plant is also slowly above carried a segment distance by lifting means simultaneously, then
By slow one segment distance of decentralization of underground silt cleaning plant, driver drive that rotary shaft 3 and screw blade 7 rotate it is same
When, lifting means constantly circulate it is above-mentioned by silt cleaning plant it is slow on refer to the action slowly transferred so that underground silt is clear
Manage device and impulsive force is produced to the silt in well during motion, accelerate the mixing velocity of silt and water purification, so as to improve
The speed that silt enters in inner cylinder 2, and then improve the efficiency of cleaning silt.
In the present embodiment, region corresponding with sand outlet is provided with training for sediment pipe 8 on the outside of the barrel of inner cylinder 2, and training for sediment pipe 8 is tilted
It is down-set, and the bottom of training for sediment pipe 8 is connected with self-styled flexible pipe 9.Self-styled flexible pipe 9 can be made up of canvas or rubber.Due to above-mentioned
Training for sediment pipe 8 is provided with the inner cylinder 2 of underground silt cleaning plant, one end of training for sediment pipe 8 is connected with self-styled flexible pipe 9, therefore, when opening
Open after driver, silt is from inner cylinder 2, the area entered via training for sediment pipe 8 and self-styled flexible pipe 9 between inner cylinder 2 and outer barrel 1
Domain, when entering, the silt in inner cylinder 2 and outer barrel 1 is more and more, and little by little, the silt between inner cylinder 2 and outer barrel 1 will be covered
Self-styled flexible pipe 9, so as to the opening of self-styled flexible pipe 9 be pushed down, so as to close the self-styled flexible pipe 9.It is so designed that, by underground silt
During cleaning plant is lifted away from well, the silt between inner cylinder 2 and outer barrel 1 will not turn again to inner cylinder 2
In, it would not also be dropped out again from the charging aperture 6 of inner cylinder 2.So as to add the quantity of sand and mud once cleaned out, and then improve cleaning
The efficiency of silt.
