[0011] According to the above technical solution, the screening device also includes a screw rod and a spring sheet. The screw rod is rotatably installed on the surface of the discharging rack. The spring sheet is arranged between the discharging rack and the screen plate. A reciprocating spiral groove is arranged on the circumferential surface of the screw rod. The screw rod is connected to the rotating rod through a No. 2 belt, and the movement of the screen plate is restricted by the spring sheet.

[0012] According to the above technical solution, the feeding device includes an L-shaped frame and a feeding port, the L-shaped frame is fixedly mounted on the surface of the discharging frame, and the feeding port is fixedly mounted on the inner wall of the L-shaped frame, and the fried rapeseed is added to the feeding port.

[0013] According to the above technical solution, the feeding device also includes a sliding button, a brake block, a round rod and a baffle, the sliding button is slidably mounted on the circumferential surface of the screw rod, the round rod rotates to penetrate the inner and outer walls of the feeding port, the brake block is fixedly mounted on the front side of the round rod, and the baffle is fixedly mounted on the circumferential surface of the round rod.

At this time, rapeseed is added to the feeding port, and the input of rapeseed is intermittently blocked by the rotation of the baffle.

[0014] A method for using a device for improving the production efficiency of rich-flavor rapeseed oil comprises the following steps: Step 1: Place gauze inside the filter tank, move the filter tank to the working area of ​​the pressing plate after the rapeseed is loaded, fix the position of the filter tank by the plug rod to prevent it from shifting during the pressing process, move the pressing plate downward by the cylinder to press the rapeseed, and the oil from the rapeseed is discharged through the sliding seat. During the pressing process, the scraper is driven by the rotation of the tooth block frame to clean the inner wall of the sliding seat to prevent the filter holes of the filter tank from being blocked by grease accumulation; Step 2: Release the limit of the filter tank through the brake lever to facilitate the operator to operate it, and the screen plate moves back and forth through the rotation of the driving rod. The rapeseed is screened by this force to remove impurities, so that high-quality rapeseed enters the discharge rack and is transported to the filter tank; Step 3: The sliding button is moved and contacts the brake block by rotating the screw rod, so that the baffle plate is rotated. The rotation of the baffle plate intermittently blocks the input of rapeseed.

[0015] The present invention provides a device and method for improving the production efficiency of fragrant rapeseed oil. It has the following beneficial effects: (1) The invention, through the setting of the pressing device, places the gauze inside the filter tank. When there is a sufficient amount of rapeseed inside the filter tank, the sliding seat moves to drive the filter tank to move. The filter tank is fixed by the filter tank, the fixed block, the tooth block frame, the plug rod, and the No. 1 spring, that is, the sliding seat is fixed. At this time, the output end of the cylinder moves downward to drive the pressing plate to move, the rapeseed is pressed and the oil is output through the sliding seat. The fixed filter tank can ensure that the filter tank always maintains the correct position during the pressing process, thereby improving the pressing efficiency. If the filter tank moves during the pressing process, it may result in poor pressing effect or even failure to complete the pressing process. The tooth block frame is driven to rotate by the rotating motor 1 and the gear, and the rotation of the tooth block frame drives the scraper to move. The scraper cleans the impurities accumulated inside the sliding seat, which can reduce blockage, thereby improving the oil output efficiency. It also helps to prevent impurities from mixing into the oil product, thereby ensuring the purity and quality of the oil product.

[0016] (2) The invention, through the setting of the screening device, uses the knob, brake rod and round block to make the block rod disengage from the fixed block, and then the sliding seat can be freely moved. By releasing the limit of the sliding seat, the operator can conveniently operate the filter tank after the pressing is completed. The screen plate is moved by rotating the second motor, the rotating rod, the connecting knob, the driving rod and the spring. At this time, the rapeseed on the screen plate will pass through the screen plate to the discharge rack, and some impurities that cannot enter will be discharged through the reciprocating movement of the screen plate. Screening can remove impurities in the rapeseed, such as stones, soil, straw, etc., which may affect the aroma of the rapeseed. Through screening, it can be ensured that only high-quality rapeseed enters the pressing process, thereby improving the aroma of the final product.

[0017] (3) The invention, through the setting of the feeding device, enables the sliding button to move back and forth left and right through the screw rod and the reciprocating spiral groove. The movement of the sliding button cooperates with the brake block to rotate the round rod, and the rotation of the round rod drives the baffle to rotate. At this time, rapeseed is added to the feeding port, and the input of rapeseed is intermittently blocked by the rotation of the baffle. If the rapeseed is continuously input into the sieve plate, it may cause the sieve plate to be blocked, affecting the screening effect. Intermittent blocking can avoid this situation and ensure the smooth progress of the screening process. BRIEF DESCRIPTION OF THE DRAWINGS

A device for improving the production efficiency of rich fragrant rapeseed oil according to claim 6, characterized in that: The feeding device comprises an L-shaped frame (30) and a feeding port (31); the L-shaped frame (30) is fixedly mounted on the surface of the discharging frame (24); and the feeding port (31) is fixedly mounted on the inner wall of the L-shaped frame (30).

8. A device for improving the production efficiency of rich fragrant rapeseed oil according to claim 7, characterized in that: The feeding device further comprises a sliding button (32), a brake block (33), a round rod (34) and a baffle (35), wherein the sliding button (32) is slidably mounted on the circumferential surface of the screw rod (29), the round rod (34) rotates to penetrate the inner and outer walls of the feeding port (31), the brake block (33) is fixedly mounted on the front side of the round rod (34), and the baffle (35) is fixedly mounted on the circumferential surface of the round rod (34). The sliding button (32) is threadedly connected to the reciprocating spiral groove.

9. A method for using a device for improving the production efficiency of rapeseed oil, using the device for improving the production efficiency of rapeseed oil according to claim 8, characterized in that: The following steps are involved: Step 1: gauze is placed inside the filter tank (11), and after the filter tank (11) is loaded with rapeseed, it is moved to the working area of ​​the pressing plate (4), and the position of the filter tank (11) is fixed by a plug rod (18) to prevent it from being offset during the pressing process. The pressing plate (4) is moved downward by the cylinder (3) to press the rapeseed, and the oil from the rapeseed is discharged through the sliding seat (10). During the pressing process, the scraper (16) is driven by the rotation of the tooth block frame (15) to clean the inner wall of the sliding seat (10), so as to prevent the accumulation of grease from clogging the filter holes of the filter tank (11); Step 2: The limit of the filter tank (11) is released by the brake rod (18) to facilitate the operator to operate it, and the screen plate (28) is moved back and forth by the rotation of the driving rod (27). The rapeseed is screened by this force to remove impurities, so that high-quality rapeseed enters the discharge rack (24) and is transported to the filter tank (11); Step 3: The screw rod (29) is rotated to move the sliding button (32) to contact the brake block (33) so that the baffle (35) rotates. The baffle (35) rotates to intermittently block the input of rapeseed.
