Here realize the connection to the bull stick 7 through connecting block 11, realize spacing to the bull stick 7 through ripples pearl screw 12 for when the bull stick 7 rotates, realize the rotation to connecting block 11 through ripples pearl screw 12, thereby realize the rotation to driven lever 10, here is in order to facilitate the realization to the dismantlement of filter screen case 8.

When the filter box 8 in the fixed box 1 needs to be disassembled, firstly, the sealing plate 20 is opened through the connecting piece 21, then the filter box 8 is pulled, so that the filter box 8 moves towards the direction of the sealing plate 20, the filter box 8 moves to drive the thread block 13 to move, the thread block 13 drives the screw rod 14 to move, the screw rod 14 drives the support rod 16 to move, the support rod 16 drives the positioning block 17 to move, meanwhile, the filter box 8 drives the driven rod 10 to move, so that the rod drives the connecting block 11 to move, the connecting block 11 is separated from the bead screw 12, when the positioning block 17 is positioned in the positioning groove on the positioning ring 18, the support rod 16 is limited, so that the limit relative to the screw rod 14 is realized, at this time, the rotation of the filter box 8 can be realized, because the piston cylinder 15 is fixed, and the support rod 16 is limited through the matching of the positioning block 17 and the positioning ring 18, at this time, the rotation of the filter box 8 can realize the rotation of the thread block 13, thereby make screw block 13 and lead screw 14 separate, at this moment through the restoring force of spring 19 for lead screw 14 and branch 16 are located initial condition, at this moment can take out fixed case 1 with filter screen box 8, thereby realize the washing to filter screen box 8, reduce intensity of labour, have improved the practicality of use.

When the filter screen box 8 needs to be installed after cleaning is completed, firstly, the threaded block 13 at the bottom end of the filter screen box 8 is moved to the position above the screw rod 14, at this time, the driven rod 10 and the rotating rod 7 which are positioned on one side of the filter screen box 8 are arranged in a staggered mode, so that when the filter screen box 8 moves towards the direction far away from the sealing plate 20, the driven rod 10 and the rotating rod 7 cannot abut against each other, at this time, the filter screen box 8 is pushed, the threaded block 13 on the filter screen box 8 abuts against one end, far away from the supporting rod 16, of the screw rod 14, the filter screen box 8 is rotated, at this time, the spring 19 is in a compressed state, the screw rod 14 is supported through the restoring force of the spring 19, so that when the filter screen box 8 rotates, the screw rod 14 can extend into the threaded block 13 through the restoring force of the spring 19, the screw rod 14 and the threaded block 13 are positioned, then the filter screen box 8 is moved, and the filter screen box 8 moves towards the direction far away from the piston barrel 15 primarily, thereby make locating piece 17 be located the holding ring 18 again, at this moment realize the spacing of first branch 16 through holding ring 18, make filter box 8 from rotating again, lead screw 14 and the better connection of screw piece 13, thereby can realize spacing to filter box 8, the driven lever 10 that is located on filter box 8 at this moment is located the U type directly over, promote filter box 8 and make connecting block 11 on the driven lever 10 be located the U type inslot on bull stick 7, realize spacing to connecting block 11 through ripples ball screw 12, at this moment spring 19 is in tensile state, carry out the supplementary spacing to connecting block 11 and bull stick 7 through the restoring force of spring 19.

Here, the limit of the connecting block 11 is realized through the abutting plate 22, and the rotating rod 7 is prevented from being separated from the rotating rod 7 when the connecting block 11 is driven to rotate, so that the connecting block 11 is better connected with the rotating rod 7 through the wave ball screw 12.

Compared with the prior art, the heat dissipation device for the hydraulic equipment realizes the heat dissipation of the main body through the heat dissipation mechanism, the air pump 2 accelerates the flow of air, so that the heat inside the fixed box 1 is better discharged through the communicating pipe 5 and the air outlet pipe 4, the communicating pipe 5 is spirally arranged, the contact area with the main body is increased, the heat inside the main body is better transmitted into the communicating pipe 5, the heat dissipation effect is improved, the main body is filtered through the filtering mechanism, the stirring of the main body is realized through the stirring device inside the stirring box 9, the main body is better communicated with the filtering net box 8, the filtering efficiency is improved, the disassembly of the filtering net box 8 is realized through the limiting main body, the cleaning of the filtering net box 8 is convenient to realize, the labor intensity is reduced, the service life of the main body is prolonged, the linkage of a plurality of mechanisms is realized through the same driving source, the practicability of use is improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
