The punching assembly 6 comprises a plurality of buffer springs 62 positioned on the blanking box 1, an arc plate 61 positioned on the buffer springs, a punching plate 63 fixed below the arc plate, and a plurality of through holes 64 arranged on the arc plate; the top surface of the arc plate is contacted with the transmission block 59; the length and width of the punching plate are 2-4 mm smaller than the size of the material box 21; the bottom of the four buffer springs is welded and fixed on the blanking box 1 and is used for supporting the arc plate 61 and the stamping plate 63; the arc plate 61 is in an arc shape as shown in fig. 10, and the top surface of the arc plate is supported by the buffer spring 62 and pressed by the transmission block 59, so that the arc plate and the punching plate 63 can reciprocate up and down to complete the crude oil extraction work; the middle part of the arc plate 61 is hollowed out to reduce the overall weight and the burden of the buffer spring 62, and meanwhile, the middle part is provided with a reinforcing rib to ensure that the arc plate cannot deform to influence the extraction effect in the working process; the welding of punching press board top is in the arc board bottom, moves down back in the magazine 21, because its size is 2~4mm less than the size of magazine, and the dregs of fat has buffer space, avoids transmission block 59 to snap back too big and directly with the magazine shatter when making the punching press board whereabouts impact force, and the dregs of fat is carried in a large number and is played when avoiding punching press board 63 to shift up simultaneously, reduces the unstable factor.

The blanking box 1 is provided with a filter port 11 and a leakage port 12, the inside of the blanking box is provided with a chute 13, and the blanking box is fixedly provided with a plurality of vertically arranged support columns 14 and a second guide column 15 through threaded connection; a plurality of stop blocks 16 are welded and fixed on the blanking box; the side surface of the stopper contacts with the side surface of the positioning block 231 to limit the positioning block 231 to move only linearly; the number of the supporting columns is four, the top parts of the supporting columns are connected and fixed on the top plate 3 in a threaded manner and are used for supporting the top plate, a platform 4 and a transmission assembly 5; the number of the second guide posts is four, four buffer springs 62 are respectively sleeved on the second guide posts, and the second guide posts are inserted into the through holes 64 to limit the punching plate 63 to only vertically move; the oil filtering port is positioned right below the material box 21 at the working position and is a square port for enabling the extracted crude oil to smoothly fall into the chute 13; the leakage port is positioned under the other material box, the cross section of the leakage port is in an arc shape, and the bottom of the leakage port is communicated with the chute, so that the existing liquid oil in the oil residue to be processed can fall into the chute, and the waste is prevented; the slide bar 22 is fixed on the blanking box and used for limiting the material box 21 and avoiding accidents caused by the material box shaking in the processing process; the bottom of the chute 13 is communicated with the outside, and the extracted crude oil is collected from the bottom of the chute.

The working process of the invention is as follows: placing the oil residues in the material box 21 and below the stamping plate 63, starting the motor 51 to drive the transmission block 59 to reciprocate, so that the stamping plate 63 continuously impacts the oil residues to extract crude oil, loading the oil residues to be processed into another material box 21 in the process, and buckling an upper buckle of the material box in which the oil residues are being processed with a lower buckle of the material box in which the oil residues to be processed are loaded; after crude oil is refined, the motor 51 stops rotating, the pull ring 25 is pulled to take down the extracted oil residue and the extracted material box, meanwhile, the oil residue and the material box to be processed are transferred to a working position, the motor is restarted to carry out oil refining, the treated residue is cleaned and loaded into the residue to be processed, the two material boxes are buckled, and continuous and repeated crude oil extraction is carried out.
