Piston rods of the first driving device 12 penetrate through a set of first guide sealing assembly 15, and the first sealing assembly 151 can effectively remove impurities such as dust, sludge and the like on the piston rods, so that the piston rods are guaranteed to be clean, and dirty objects are prevented from being brought back into the oil cylinders; the first guide sleeve 152 has a guiding effect on the piston rod, so that abrasion of the piston rod and the cylinder head part of the oil cylinder body caused by offset load force in the extending process of the piston rod can be reduced, and the safety of the piston rod in the using process is guaranteed.

In this embodiment, the first extrusion head 11 is a square column structure with an inner hole in the middle, and is installed and fixed at the other end of the connecting section 14, and the inner hole is used for fixing with the connecting section 14 and can be freely detached. One end of the extrusion head mounting seat 16 is fixed on a plane on one side of the extrusion movable beam 24, the second guide sealing assemblies 17 of each group in the first extrusion mechanism are fixed at the other end of the extrusion head mounting seat 16, and the movement of a piston rod of each first driving device 12 (hydraulic oil cylinder) can drive one connecting section 14 mounted on the first driving device to move, and then drive one first extrusion head 11 mounted on the connecting section 14 to move back and forth to extrude sludge in front of the first extrusion head.
The extrusion device is used for extruding and removing impurities of the materials containing the impurities entering the sludge bin 93 and separating the impurities from the sludge. The working process is as follows: piston rods of a first driving device 12 (a hydraulic oil cylinder) of the first extrusion mechanism all return to the last position, and the front end faces of first extrusion heads 11 of the first extrusion mechanisms are flush, so that spaces for bearing sludge are formed among the front end faces of second extrusion heads 21 formed by splicing all the first extrusion heads 11, a sludge bin 93, a sludge discharge grid 92, an upper sealing door 94 and a lower sealing door 95. The lower sealing door 95 is initially in a forward most position (shown as the leftmost position in fig. 11) to block the interior of the sludge tank 93 from the environment. The upper sealing door 94 moves backward to the final position (the rightmost position shown in fig. 11) to communicate the sludge temporary storage bin 96 with the cavity of the sludge box 93, and the impurity-containing sludge material originally on the upper sealing door 94 in the sludge temporary storage bin 96 falls into the cavity of the sludge box 93 under the action of gravity. Then, the upper sealing door 9 is driven to move to the foremost position (leftmost position shown in fig. 11) to block the sludge temporary storage bin 96 and the sludge box 93 from communicating, and the impurity-containing sludge material is enclosed in the space between the sludge box 93 cavity, the upper sealing door 94, the lower sealing door 95, the second extrusion head 21 and the sludge discharge barrier 92. After the work begins, the piston rods of the two extrusion hydraulic oil cylinders (the second driving device 22) extend out, the extrusion movable beam 24 is driven to drive the second extrusion head 21 formed by splicing the 9 groups of first extrusion heads 11 installed on the extrusion movable beam to move forwards along the length direction of the guide upright column, sludge materials are compressed, and only the sludge barrier 92 is provided with grid holes in the original space, so that the sludge materials can be extruded out of the holes of the sludge barrier 92 only, and are discharged to the outside from a crushed sludge outlet under the action of gravity.
If no impurities exist in the sludge or the size of the impurities is smaller than the size of the holes formed in the sludge discharge barrier 92, the piston rods of the two extrusion hydraulic cylinders (the second driving device 22) can reach the maximum stroke when extending out, the front end surfaces of the 9 first extrusion heads 11 are simultaneously moved forwards to positions close to the inner side of the sludge discharge barrier 92, and the first driving devices 12 in the 9 first extrusion heads 11 do not act in the whole process.
When the size of impurities contained in the sludge is larger than that of holes formed in the sludge discharging barrier 92, piston rods of two extrusion hydraulic cylinders (second driving devices 22) extend out to drive the front end face of a second extrusion head 21 consisting of 9 first extrusion heads 11 to move forwards to compress the sludge until the impurities simultaneously contact the inner side of the sludge discharging barrier 92 and the front end face of the second extrusion head 21, the extrusion head assemblies are prevented by the impurities from moving forwards continuously, so that the pressure of hydraulic oil in the two extrusion hydraulic cylinders (second driving devices 22) rises, and when a set value is reached, the two extrusion hydraulic cylinders (second driving devices 22) stop moving forwards. At the moment, hydraulic oil is supplied to the 9 sub-oil cylinders (the first driving device 12) simultaneously, and due to the blocking effect of impurities, all the extrusion head assemblies with the impurities in front cannot move forwards, and the extrusion head assemblies without the impurities in front continue to move forwards under the driving of the sub-oil cylinders (the first driving device 12) on the extrusion head assemblies to compress sludge until the extrusion head assemblies are close to the inner side of the sludge discharge barrier 92. If there are smaller sized foreign objects blocking the advancing extrusion head assembly during the advance, the blocked extrusion head assembly will also stop advancing.
Example 5

In the first extrusion head 11 shown in fig. 7, the extrusion section 13 is square, the connecting section 14 is diamond-shaped, and the connecting section 14 away from the extrusion section 13 may be of equal shape for connection with the first driving device 12.

Example 6

The first extrusion head guide member 18 can provide a guiding function for the advance or retreat of the first extrusion head 11, provide radial force for the connecting section and reduce the abrasion caused by uneven force during the extrusion process. When the first driving device 12 drives the first extrusion head 11 to advance alone, the first extrusion head 11 penetrates out of the mud scraper assembly 19, that is, the front end of the first extrusion head 11 exceeds the mud scraper assembly 19, and when the first extrusion head 11 retracts, the mud scraper assembly 19 can scrape out the sludge adhered to the first extrusion head 11, so that an effective cleaning effect is achieved.
The first driving devices 12 are hydraulic oil cylinders, the first driving devices 12 are communicated through pipelines, and a set of hydraulic system is adopted for controlling, so that the first driving devices 12 operate in a linkage mode.
Because a set of hydraulic system control is adopted, in the process that the first driving device 12 drives the first extrusion heads 11 to advance to extrude mud, each first extrusion head 11 can independently advance (without head aligning and advancing) according to different resistances, so that the running distances of the extrusion sections 13 are different, large pieces of mud are prevented from being adhered to the end surfaces of the extrusion sections 13, and the effect of scraping the mud on the side surfaces of the extrusion sections is also realized when the first extrusion heads 11 retract backwards.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
