Description

Technical Field

[0001] This utility model relates to the technical field of rapeseed oil processing equipment, specifically a rapeseed oil pressing device. Background Technology

[0002] Rapeseed oil pressing has a long history in my country. The traditional manual pressing method mainly uses the lever principle, using human power to drive wooden wedges to squeeze rapeseed to extract oil. With the development of industrial technology, small-scale mechanical pressing equipment has gradually emerged.

[0003] In existing technologies, the feeding device is mostly connected to the machine body through a feeding hopper and a connecting pipe. The connecting pipe is directly connected to the inlet of the pressing chamber. During pressing, rapeseed is poured into the feeding hopper and reaches the pressing chamber through the connecting pipe. The rotation of the screw shaft causes the rapeseed to be squeezed and rubbed in the pressing chamber, thereby squeezing out the oil.

[0004] However, the connecting pipe of the oil press is connected to the feed hopper. It is difficult to adjust the material flow rate through the connecting pipe. If the feeding speed is too fast, the rapeseed may accumulate in the feed pipe or pretreatment device, causing blockage. In addition, the rapeseed often contains impurities such as stones and metal fragments, which will enter the pressing equipment during oil pressing and cause damage to the internal components. Utility Model Content

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: a rapeseed oil pressing device, including an oil press body 1. The top of the oil press body 1 is integrally formed with a connecting pipe 2, and the top of the connecting pipe 2 is connected to a feed hopper 3. A shaft 7 is rotatably connected to the surface of the feed hopper 3. A stirring rod 6 is fixedly connected to both sides of the surface of the shaft 7. A scraper 11 is provided at the bottom end of the shaft 7. A screen plate 10 is fixedly connected to the surface of the connecting pipe 2. The scraper 11 is attached to the surface of the screen plate 10. An adjusting plate 12 is rotatably connected to the surface of the connecting pipe 2. The stirring rod 6 in the feed hopper 3 prevents rapeseed from accumulating and clumping, which could lead to blockage. The screen plate 10 and scraper 11 in the connecting pipe 2 can prevent impurities from entering the interior of the pressing device. The scraper 11 can clean the surface of the screen plate 10 in time to keep the screen holes unobstructed. By setting the adjusting plate 12, the feed flow rate can be adjusted to adapt to the working state of the oil press body 1 and improve the working efficiency of the oil press body 1.

[0024] Example 2

[0025] Please see Figures 1 to 4 Based on Embodiment 1, in order to prevent blockage inside the oil press body 1, a horizontal plate 5 is fixedly connected to the top surface of the feed hopper 3. The horizontal plate 5 is used to support the servo motor 4. The top of the horizontal plate 5 is fixedly connected to the servo motor 4. One end of the shaft 7 is connected to the output end of the servo motor 4. Two stirring rods 6 are symmetrically distributed on the surface of the shaft 7. The stirring rods 6 can stir the rapeseed entering the feed hopper 3, which helps to break up the clumps of rapeseed and make the rapeseed more evenly distributed in the feed hopper 3.

[0026] A linkage rod 8 is fixedly connected to the bottom end of the shaft 7. The linkage rod 8 has a T-shaped circular plate structure and passes through the center of the screen plate 10. The diameter of the linkage rod 8 is smaller than the diameter of the shaft 7. The linkage rod 8 can drive the scraper 11 to rotate synchronously with the shaft 7.

[0027] Square grooves are provided on both sides of the surface of the linkage rod 8. A fixing plate 15 is slidably connected to the surface of the square groove. The fixing plate 15 has a square plate structure. A rubber sleeve 14 is fixedly connected to the surface of the fixing plate 15. The other end of the rubber sleeve 14 is fixedly connected to the surface of the annular groove. Two scrapers 11 are fixedly connected to the surface of the fixing plate 15. The rubber sleeve 14 is in a compressed state and has a tendency to recover to its original state. When the surface of the scraper 11 is worn after long-term use, the rubber sleeve 14 will always provide elasticity to the scraper 11, so that the scraper 11 always adheres to the surface of the screen plate 10.

[0028] Example 3

[0029] Please see Figures 1 to 5 Based on Example 2, in order to adjust the amount of rapeseed feed, the adjustment plate 12 has a circular plate structure. By rotating the adjustment plate 12, the relative position relationship with the connecting pipe 2 can be changed, thereby effectively controlling the flow rate of rapeseed in the connecting pipe 2 and realizing precise adjustment of the feed flow rate to adapt to different pressing process requirements and raw material characteristics.

[0030] The surface of the adjusting plate 12 has a circular hole, and a connecting rod 13 is fixedly connected to the surface of the circular hole. One end of the connecting rod 13 is rotatably connected to the inner wall of the connecting pipe 2, and the other end of the connecting rod 13 extends through to the top surface of the connecting pipe 2. A limiting plate 19 is fixedly connected to one side of the surface of the connecting pipe 2. The surface of the limiting plate 19 has multiple toothed grooves. A handwheel 9 is fixedly connected to one end of the connecting rod 13, which facilitates the operation of the adjusting plate 12 by the operator. Sliding grooves 20 are formed on both sides of the surface of the connecting rod 13. A rubber block 16 is fixedly connected to the surface of the sliding groove 20 away from the handwheel 9. The rubber block 16 has a pulling effect on the toothed plate 18 and the slider 17, which prevents the toothed plate 18 and the limiting plate 19 from separating due to vibration. A slider 17 is fixedly connected to one end of the rubber block 16. The slider 17 drives the toothed plate 18 to slide on the surface of the connecting rod 13, and the toothed plate 18 can rotate synchronously with the connecting rod 13.

[0031] Two sliders 17 are fixedly connected to toothed plates 18, which are slidably connected to the surface of connecting rod 13. The surface of toothed plates 18 is provided with multiple teeth arranged in an array. One end of toothed plates 18 is embedded in limiting plate 19 to brake adjusting plate 12. The grooves on the surface of limiting plate 19 and the teeth of toothed plates 18 cooperate with each other. When one end of toothed plates 18 is embedded in limiting plate 19, it can brake adjusting plate 12 and fix it in the set position, thereby locking the feed flow rate.

[0032] In actual use, first pull the toothed plate 18 towards the handwheel 9 to separate the toothed plate 18 from the toothed groove in the limiting plate 19. At this time, the rubber block 16 changes from its original state to a stretched state. Then rotate the handwheel 9, which drives the connecting rod 13 and the adjusting plate 12 to rotate, adjusting the opening and closing degree of the adjusting plate 12 and the connecting pipe 2. After adjustment, align the teeth on the surface of the toothed plate 18 and embed them into the toothed groove on the surface of the limiting plate 19. Then pour rapeseed into the feed hopper 3. Drive the shaft 7 and the stirring rod 6 to rotate through the servo motor 4. The stirring rod 6 stirs the rapeseed to prevent it from accumulating and clumping, which would cause blockage. The rapeseed passes through the sieve plate 10, which intercepts impurities. The shaft 7 drives the bottom linkage rod 8 and the scraper 11 on its surface to rotate. The scraper 11 adheres to the surface of the sieve plate 10 to prevent impurities from clogging the sieve holes.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
