Technical Field
[0001] This utility model relates to the technical field of oil pressing equipment, specifically a rapeseed oil pressing device. Background Technology
[0002] Oil pressing, an agricultural science term, refers to the process of converting crops such as peanuts, sunflower seeds, and sesame seeds into oil. Currently, oil pressing equipment includes horizontal and vertical types. Among them, the vertical oil pressing equipment uses a hydraulic cylinder to press the material placed in the pressing cylinder, which is simple to operate and yields a high oil output.
[0003] A search revealed a Chinese patent publication number, CN221969039U, which discloses an oil pressing device. The device includes a base plate with a first support and a second support. A first hydraulic cylinder is mounted on the first support, and a pressing disc for pressing materials is rotatably mounted on the first hydraulic cylinder. The device rotates an oil pressing cylinder inside a container. After the first hydraulic cylinder presses the material inside the cylinder through the pressing disc, it stops. Then, a motor is started, driving the oil pressing cylinder to rotate via a transmission unit. This causes the oil on the oil pressing cylinder to be thrown onto the inner wall of the container, allowing the oil to quickly detach from the cylinder, saving time and improving work efficiency.
[0004] Although the aforementioned patent allows the oil to be quickly removed from the oil press, the device still has the following problems: during use, the pressed oil is prone to splashing onto the inner wall of the barrel, leaving a large amount of oil residue, which reduces the oil extraction rate of rapeseed. Furthermore, the oil adhering to the barrel wall for a long time makes it difficult to clean the inner wall, making subsequent cleaning of the barrel more troublesome. In view of the above, technical innovation is carried out on the basis of the existing device. Utility Model Content
[0005] The purpose of this invention is to provide a rapeseed oil pressing device to solve the problems mentioned in the background art.

[0023] Please see Figure 1-5This utility model provides a technical solution: a rapeseed oil pressing device, including a device body 22, a tank 1 mounted on the device body 22, and an oil pressing device (see patent: CN221969039U) mounted on the device body 22. An annular bottom plate 18 is fixedly connected to the lower surface of the tank 1. An annular groove 20 is formed inside the annular bottom plate 18, penetrating the bottom of the tank 1. The cross-section of the annular groove 20 is T-shaped. A T-shaped ring 19 is rotatably connected inside the annular groove 20. A toothed ring 14 is fixedly connected to the bottom of the T-shaped ring 19, and the surface of the toothed ring 14 is slidably connected to the inside of the annular groove 20. A motor 6 is mounted inside the annular bottom plate 18, and a gear 17 is fixedly connected to the output end of the motor 6. The gear 17 is located inside the annular groove 20, and the inner surface of the toothed ring 14 meshes with the surface of the gear 17 through teeth. Four second scrapers 5 are evenly fixedly connected to the top of the T-shaped ring 19. The T-shaped ring 19 rotates... The second scraper 5 is moved, and oil scraping brushes 13 are provided on the left, right and bottom sides of the second scraper 5. A T-shaped limiting ring 15 is fixedly connected to the inner surface of the tank 1. The inside of the second scraper 5 is slidably connected to the surface of the T-shaped limiting ring. An oil outlet pipe 16 is provided at the bottom of the tank 1. The pressed oil can be discharged through the oil outlet pipe 16. The operator starts the motor 6. The motor 6 rotates and drives the gear 17 to rotate, causing the moving gear ring 14 of the gear 17 to rotate. Under the rotation of the gear ring 14, the four second scrapers 5 start to rotate. Under the action of the oil scraping brushes 13 on the second scraper 5, the rapeseed oil on the inner surface of the tank 1 and the lower inner surface of the tank 1 can be scraped and sent to the oil outlet pipe 16 to complete the collection of rapeseed oil in the tank. This scraping can collect rapeseed oil better, reduce rapeseed oil waste, and reduce oil residue in the tank 1 to a certain extent, so as to improve the oil collection rate.
[0024] An annular oil-blocking inclined plate 7 is fixedly connected to the lower inner surface of the tank 1. The annular oil-blocking inclined plate 7 prevents oil leakage. An annular oil-blocking block 8 is fixedly connected to the top of the annular oil-blocking inclined plate 7. An oil pressing barrel 2 is set on the top of the annular oil-blocking block 8. The inside of the oil pressing barrel 2 can hold rapeseed, and the oil is pressed by starting the tank 1. A sliding groove 21 is opened at the bottom of the oil pressing barrel 2. The inside of the sliding groove 21 is slidably connected to the surface of the annular oil-blocking block 8. An oil drain 9 extending to the outside of the oil pressing barrel 2 is opened inside the oil pressing barrel 2. The oil drain 9 can filter the oil and block waste. Four limiting grooves 12 are evenly opened on the outer surface of the annular oil-blocking inclined plate 7. The limiting grooves 12 are located on the inclined surface. A support plate 11 is inserted into the inside of the limiting groove 12. A collecting ring 10 is fixedly connected to the upper surface of the support plate 11. A groove is opened on the top of the collecting ring 10. A gear ring mechanism is placed in the groove for connection and support. A mesh extending to the outside of the collecting ring 10 is opened inside the collecting ring 10. The mesh facilitates oil drainage. A filter screen 4 is fixedly connected to the upper surface of the collecting ring 10. The filter screen 4 can block and filter impurities in the discharged oil, reducing the impurity content in the oil to a certain extent and ensuring the quality of rapeseed oil extraction. The inner surface of the collecting ring 10 is in contact with the outer surface of the annular oil baffle 8. A first scraper 3 is fixedly connected to the outer surface of the oil pressing barrel 2. An oil scraping brush 13 is provided on the surface of the first scraper 3 near the screen. The first scraper 3 drives the oil scraping brush 13 to rotate, which facilitates the scraping of rapeseed oil on the filter screen and avoids the loss and waste of rapeseed oil. The pressed rapeseed oil passes through the oil outlet 9 and is then filtered on the filter screen 4. The oil residue produced by filtration falls into the collecting ring 10 for collection through the first scraper 3. When cleaning the device, firstly, the oil pressing barrel is pulled out through the first scraper 3, then the filter screen 4 is pulled out, and the oil residue accumulated in the collecting ring 10 is poured out for cleaning.
[0025] Working Principle: For this type of rapeseed oil pressing device, the operator first pours rapeseed into the oil pressing barrel 2 and starts the transmission mechanism fixed on the main body 22 of the equipment. The transmission mechanism has been described in detail in reference patent CN221969039U and will not be repeated here. The transmission mechanism drives the oil pressing barrel 2 to rotate, and starts the hydraulic cylinder to move downward to press the rapeseed oil in the oil pressing barrel 2. After pressing out the rapeseed oil, the pressed rapeseed oil is thrown through the filter screen 4. The filter screen 4 filters the pressed rapeseed oil. The rapeseed residue produced by the filter will fall into the collection ring 10 for collection under the action of the first scraper 3. The filtered rapeseed oil will be on the lower surface of the inside of the barrel 1. The operator starts the motor 6, and the motor 6 drives the second scraper 5 to move, scraping the rapeseed oil to the designated oil outlet pipe 16 to complete the oil pressing work. During cleaning, the operator can pull out the oil pressing barrel through the first scraper 3, and then pull out the filter screen 4 to pour out the oil residue and complete the cleaning work.
