DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figure 1 to Figure 2 As shown, a peanut oil pressing device according to an embodiment of the present invention comprises a screw press 1, a feed hopper 11 is installed at the top of the screw press 1, an oil outlet hopper 12 is fixed inside the screw press 1, a slag discharge port 13 is arranged on one side of the screw press 1, and a post-processing component for squeezing residual oil in the oil residue is arranged at one end of the screw press 1 close to the slag discharge port 13; the post-processing component comprises a slag collecting box 2 arranged at one end of the screw press 1 close to the slag discharge port 13, and a support frame 3 is arranged on the side of the slag collecting box 2 away from the screw press 1;

[0033] In the production process of peanut oil, it is necessary to first squeeze out peanut oil from peanuts, drive the screw press 1 to operate through an external power source, and then put the peanuts into the feed hopper 11. At this time, the peanuts enter the screw press 1 through the feed hopper 11 and are squeezed out of peanut oil. The peanut oil flows out through the oil outlet hopper 12 and is collected. The oil residue after squeezing will be discharged through the residue discharge port 13, and the discharged oil residue enters the residue collecting box 2, and then the residual oil inside is squeezed out by the post-processing component. By directly processing the oil residue, the time consumed by squeezing the oil residue through the screw press 1 again is reduced.

[0034] like Figures 2 to 4As shown, a slag inlet 21 is provided at the top of the slag collecting box 2, a conveying port 23 is provided at the side of the slag collecting box 2 close to the supporting frame 3, a turning box 22 is rotatably connected inside the slag inlet 21, and a first pulley 221 is fixed at one end of the turning box 22;

[0035] When the oil residue is discharged from the slag discharge port 13, the oil residue falls into the slag inlet 21 inside the slag collecting box 2, and then falls on the top of the turning box 22. The turning box 22 can store the oil residue inside the slag inlet 21 within a set time.

[0036] like Figures 4 to 5 As shown, a first motor 31 is installed at the top of the support frame 3, a rotating shaft 32 is rotatably connected inside the support frame 3, a toothed disc 321 is fixed at the top of the rotating shaft 32, the first motor 31 is meshed and connected with the toothed disc 321 through an output gear at the end, a second pulley 322 is fixed at the middle of the rotating shaft 32, a double-layer pulley 33 is rotatably connected at one end of the support frame 3 near the first pulley 221, the second pulley 322 is rotatably connected to the double-layer pulley 33 through a belt, and the double-layer pulley 33 is rotatably connected to the first pulley 221 through a belt;

[0037] After the set time is up, the first motor 31 is started to drive the toothed disc 321 to rotate, the toothed disc 321 drives the rotating shaft 32 to rotate, the rotating shaft 32 drives the second pulley 322 to rotate, the second pulley 322 drives the double-layer pulley 33 to rotate via the belt, the double-layer pulley 33 drives the first pulley 221 to rotate via the belt, at this time the first pulley 221 drives the flip box 22 to flip, when the flip box 22 flips 120°, the first motor 31 stops rotating, during this process the flip box 22 will discharge the oil residue at the top into the interior of the conveying port 23, and at the same time the other side of the flip box 22 flips to the top, and during the flipping process of the front side of the flip box 22, the oil residue dropped from the slag discharge port 13 is received.

[0038] like Figures 4 to 5 As shown, three material storage troughs 34 are fixed at equal intervals at the bottom end of the rotating shaft 32, a plurality of oil outlet holes are opened at equal intervals below the outer side wall of the material storage trough 34, a docking port 231 matching the rotation trajectory of the material storage trough 34 is opened below the delivery port 23, and a material baffle is provided at the top end of the material storage trough 34;

[0039] When the rotating shaft 32 rotates, it will drive the storage trough 34 to rotate. The flip box 22 flips 120° and drives the rotating shaft 32 to rotate 120° at the same time. At this time, the rotating shaft 32 drives one of the storage troughs 34 to leave the interior of the docking port 231 and moves the other storage trough 34 into the interior of the docking port 231. At this time, the oil residue falls into the storage trough 34. During the flipping process of the flip box 22, the material baffle of the storage trough 34 can catch part of the oil residue to prevent it from falling.

[0040] like Figures 5 and 6 As shown, a bracket 356 is fixed to one side of the support frame 3, a hydraulic cylinder 35 is fixed to the bottom end of the bracket 356, and a pressing plate 351 is fixed to the bottom end of the hydraulic cylinder 35;

[0041] After receiving the oil residue, the storage tank 34 continues to rotate 120°. At this time, the storage tank 34 is below the pressing plate 351. Then, the hydraulic cylinder 35 is started to drive the pressing plate 351 to squeeze the oil residue into the storage tank 34. After the oil residue is squeezed, the residual grease inside can be squeezed out, and the squeezed grease is discharged through the oil outlet hole of the storage tank 34.

[0042] like Figures 5 to 8 As shown, a collecting frame 37 is provided below the pressing plate 351, and the collecting frame 37 is below the material storage tank 34. Three threaded sleeves 371 are fixed at equal intervals on the outside of the collecting frame 37. A second motor 372 is provided below the threaded sleeve 371. A threaded column is fixed to the end of the rotating shaft of the second motor 372. The threaded column and the threaded sleeve 371 are threadedly connected. An oil discharge nozzle 373 is provided at one end of the collecting frame 37.

[0043] After the storage tank 34 flips 120°, the second motor 372 rotates through the threaded column to drive the threaded sleeve 371 to push the collecting frame 37 upward. The collecting frame 37 can wrap and support the bottom of the storage tank 34. The oil discharged from the oil outlet of the storage tank 34 is collected by the collecting frame 37 and discharged to the outside through the oil discharge nozzle 373.

[0044] like Figure 6 to Figure 7 As shown, a plurality of plug plates 36 are fixed at equal intervals at the bottom end of the pressing plate 351, a flip plate 361 is arranged below the plug plate 36, hinge blocks 362 are fixed on both sides of the top of the flip plate 361, a positioning groove 363 is provided inside the hinge block 362, notches matching the hinge block 362 are provided on both sides of the bottom end of the plug plate 36, a hinge column 364 is fixed to the side wall of the notch, the hinge column 364 is rotatably connected to the inside of the hinge block 362, a fixing spring 365 is fixed inside the hinge column 364, a steel ball 366 is fixed to one end of the fixing spring 365, and the positioning groove 363 engages with the steel ball 366 after the flip plate 361 is flipped 90° toward the center direction of the pressing plate 351;

[0045] When the pressing plate 351 is pressed into the storage tank 34, the inserting plate 36 and the flipping plate 361 are driven to insert into the oil residue. At this time, due to the curvature set at the bottom of the flipping plate 361, the flipping plate 361 can contact the bottom end of the storage tank 34 and then flip 90°. At this time, the position of the positioning groove 363 matches the position of the steel ball 366, and the fixing spring 365 pushes the steel ball 366 to be stuck into the interior of the positioning groove 363, so that the inserting plate 36 and the flipping plate 361 can be fixed. At this time, the inserting plate 36 and the flipping plate 361 are L-shaped, so that the squeezed oil cake can be fixed under the pressing plate 351.

[0046] like Figure 6 to Figure 7 As shown, a slag pushing plate 352 is provided below the pressing plate 351, a plurality of push posts 353 distributed at equal intervals are fixed to the top of the slag pushing plate 352, a connecting ring 355 is fixed to the top of the push posts 353, a return spring 354 is sleeved on the outside of the push posts 353, the bottom end of the return spring 354 is fixedly connected to the pressing plate 351, and the top end of the return spring 354 is fixedly connected to the connecting ring 355;

[0047] After squeezing, the hydraulic cylinder 35 is started to drive the pressing plate 351 to move out from the inside of the storage tank 34. At this time, the oil residue is squeezed into oil cakes and pulled out under the action of the insert plate 36 and the flip plate 361. At this time, the connecting ring 355 is pushed to drive the slag pushing plate 352 to move downward through the pushing column 353. The slag pushing plate 352 pushes the oil cake downward, so that the oil cake can fall off from the bottom of the pressing plate 351. At the same time, under the action of the slag pushing plate 352, the flip plate 361 can be reversed and in a vertical state with the insert plate 36. Then the connecting ring 355 is loosened, and the reset spring 354 can drive the connecting ring 355 to rise to reset the slag pushing plate 352.

[0048] like Fig. 9 As shown, a slag receiving plate 38 is provided between the pressing plate 351 and the material storage tank 34, a flip frame 381 is fixed to the side of the slag receiving plate 38 away from the support frame 3, the bottom end of the flip frame 381 is rotatably connected to a support column 385, a third motor 384 is installed inside the support column 385, the end of the rotating shaft of the third motor 384 is fixedly connected to the bottom end of the flip frame 381, and the bottom end of the support column 385 is fixed on the ground;

[0049] Before the pressing plate 351 discharges slag, the third motor 384 is started to drive the turning frame 381 to rotate, and the turning frame 381 drives the slag receiving plate 38 to move into the position between the pressing plate 351 and the storage trough 34. When the oil cake falls, the slag receiving plate 38 catches the oil cake. Then the third motor 384 drives the slag receiving plate 38 to rotate in the opposite direction to move the slag receiving plate 38 out from between the storage trough 34 and the pressing plate 351, and then the oil residue inside the slag receiving plate 38 is collected.

[0050] like Fig. 9As shown, an electric telescopic rod 382 is installed at the top of the flip frame 381, and a push plate 383 is fixed at the bottom end of the electric telescopic rod 382;

[0051] When the slag receiving plate 38 is turned over, the electric telescopic rod 382 is driven to move above the connecting ring 355. When discharging slag, the electric telescopic rod 382 is started to drive the push plate 383 to push the connecting ring 355 to discharge slag. After discharging slag, the electric telescopic rod 382 drives the push plate 383 to reset.
