[0035] Reference Figure 1 , Figure 3 , Figure 4The sealing assembly includes a rubber pad 51. A handle is fixedly connected to the front surface of the drawer 42 for easy gripping. A lock is provided on the front surface of the drawer 42. The lock, the motor 41 and the oil press 1 are prior art and can be implemented by technicians in this field. Since they are prior art, they will not be described in detail in this case. The lock is divided into two parts, one part is fixed to the front surface of the drawer 42, and the other part is fixed to the front surface of the oil press 1. The lock can connect the drawer 42 and the oil press 1. The inner wall of the oil press 1 is elastically connected to the rubber ring 52 through a connecting spring 53.

[0036] Reference Figure 1 , Figure 3 , Figure 4 The rubber pad 51 and the rubber ring 52 are arranged in a ring shape, the front surface of the rubber pad 51 is fixedly connected to the rear surface of the drawer 42, the rubber ring 52 is slidably connected to the inner wall of the oil press 1, the outer wall of the rubber ring 52 is in contact with the oil press 1, one end of the connecting spring 53 is fixedly connected to the rear surface of the rubber ring 52, and the other end of the connecting spring 53 is fixedly connected to the inner wall of the rear side of the oil press 1.

The rubber pad 51 is inserted into the inner wall of the oil press 1, and when the rubber pad 51 and the oil press 1 are in contact, it will squeeze the connecting spring 53 to generate a reaction force.

[0037] Reference Figure 1 , Figure 2 , Figure 5 The motor 41 is arranged on the front surface of the oil press 1, the rotating shaft 44 penetrates and is rotatably connected to the front surface of the oil press 1, and the centers of the rotating shaft 44 and the rotating disk 45 are located on the same horizontal line.

The two groups of drawers 42 are symmetrically distributed up and down along the center line of the turntable 45. The mesh aperture of the filter plate 43 arranged in the upper position drawer 42 is larger, and the mesh aperture of the filter plate 43 arranged in the lower position drawer 42 is smaller.

[0039] Reference Figure 3 , Figure 5 , Figure 6 One end of the compression spring 49 is fixedly connected to the lower surface of the slide rod 410, and the other end of the compression spring 49 is fixedly connected to the inner wall of the bottom end of the hollow tube 48. When the slide rod 410 moves downward, it will squeeze the compression spring 49 to generate a reaction force. The slide rod 410 passes through and is slidably connected to the upper surface of the hollow tube 48.

[0040] Reference Figure 3 , Figure 5 , Figure 6The upper surface of the positioning block 47 is set to be an arc surface. When the arc surface of the positioning block 47 is squeezed, it will move downward, and the filter plate 43 is slidably connected to the inner wall of the drawer 42.

[0041] Working principle: When the device is used, the crops to be pressed for oil are first poured from the lower hopper 2 into the oil press 1. The crops entering the oil press 1 will be crushed and squeezed for oil. The squeezed oil and a small amount of crop residue will move downward and fall on the upper filter plate 43. The larger crop residue will be blocked, and the oil and the smaller residue will continue to move downward through the upper filter plate 43 to the lower filter plate 43. The smaller residue will be blocked by the smaller filter plate 43. The oil can pass through and finally flow out from the oil outlet bin 3 and be collected.

[0042] When the crop residues contact the two groups of filter plates 43, they are easily accumulated on the filter plates 43. In order to prevent the residues from clogging the mesh, the motor 41 can be started to drive the rotating shaft 44 and the turntable 45 to rotate. The rotating turntable 45 will drive the positioning plate 46 to move. The moving positioning plate 46 will squeeze the arc surface of the positioning block 47 to make the positioning block 47 move longitudinally. The longitudinally moving positioning block 47 will drive the filter plates 43 and the slide bar 410 to move longitudinally. The longitudinally moving slide bar 410 will squeeze the compression spring 49 to generate a reaction force. Under the influence of the reaction force of the compression spring 49, the slide bar 410, the filter plates 43 and the positioning block 47 will shake longitudinally to shake off the crop residues, which can achieve an anti-clogging effect.

[0043] After the oil pressing is completed, the motor 41 is turned off and the lock is unlocked. After the unlocking is completed, the drawer 42 is pulled out to clean the crop residues remaining on the drawer 42 and to replace and repair the drawer 42. After the cleaning is completed, the drawer 42 is inserted into the oil press 1. When the drawer 42 is inserted into the oil press 1, the rubber pad 51 will be plugged into the oil press 1 and will squeeze the rubber ring 52 so that the rubber ring 52 moves backward to squeeze the connecting spring 53 to generate a reaction force. Under the influence of the reaction force of the connecting spring 53, the rubber ring 52 and the rubber pad 51 will be tightly attached to form a seal to prevent oil leakage. After the drawer 42 is inserted, the lock is locked.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
