[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0027] As Figure 2 and Figure 3 shown, this embodiment provides a technical solution: a screw press for walnut oil extraction, including a support frame 1. The support frame 1 includes a feeding port 11. The bottom of the feeding port 11 is provided with a pressing shaft 12. The side of the pressing shaft 12 is fixedly connected with a converging groove 13. The side of the converging groove 13 is provided with a pressing component 2

[0028] The pressing assembly 2 includes a first disc 21. A first limiting groove 29 is formed on the side surface of the first disc 21. A first connecting rod 22 is slidably connected to the inner cavity of the first limiting groove 29. A rotating shaft 23 is rotatably connected to the middle of the first connecting rod 22. One end of the first connecting rod 22 away from the first disc 21 is rotatably connected to a second connecting rod 24. A second support plate 28 is fixedly connected to the side surface of the second connecting rod 24. A first support plate 25 is fixedly connected to the side surface of the second support plate 28. One end of the first support plate 25 away from the second support plate 28 is fixedly connected to a fixing rod 26. A elastic sheet 27 is fixedly connected to the bottom of the fixing rod 26. A motor is arranged on the side surface of the first disc 21. The position of the rotating shaft 23 is fixed. A pressing head is arranged at the bottom of the fixing rod 26. By starting the motor, the output shaft of the motor rotates forward, so as to drive the first disc 21 to rotate. When the first disc 21 rotates, it can drive the first connecting rod 22 to move along the inner cavity of the first limiting groove 29. By setting the shape of the first limiting groove 29 to have a certain slope, one end of the first connecting rod 22 can be promoted to move upward. When one end of the first connecting rod 22 moves upward, through the cooperation with the rotating shaft 23, the other end of the first connecting rod 22 can be promoted to move downward, and then the second connecting rod 24 can be driven to move downward. When the second connecting rod 24 moves downward, it can drive the first support plate 25 to move downward through the second support plate 28, so as to promote the fixing rod 26 to move downward, and then drive the pressing head arranged at the bottom of the fixing rod 26 to perform secondary pressing on the walnuts that have not been fully pressed. When the pressing head contacts the walnuts, the elastic sheet 27 arranged on the top of the pressing head will be compressed, so as to absorb the stress. When the stress is absorbed to a certain extent, the stress is released, and then the walnuts can be further pressed, ensuring the completion rate of pressing, significantly improving the oil yield, and at the same time, the residual impurities and moisture in the walnuts can be further removed, avoiding the direct recycling of the walnuts that have not been fully pressed, resulting in waste.

[0029] Furthermore, as Figure 2 - Figure 4As shown in the figure: An interception component 3 is provided on the side of the first turntable 21. The interception component 3 includes a third connecting rod 31. A rack 32 is rotatably connected to the side of the third connecting rod 31. A second limiting block 33 is provided on the side of the rack 32. A gear 34 is rotatably connected to the inner cavity of the second limiting block 33. A first bevel gear 35 is fixedly connected to the side of the gear 34. A second bevel gear 36 is provided on the side of the first bevel gear 35. A second turntable 37 is fixedly connected to the side of the second bevel gear 36. A third limiting block 38 and a limiting rod 39 are provided on the side of the second turntable 37. A second limiting groove 312 is formed on the side of the limiting rod 39. One end of the third limiting block 38 extends into the inner cavity of the second limiting groove 312. The third limiting block 38 is slidably connected to the inner cavity of the second limiting groove 312. A transmission rod 310 is fixedly connected to the bottom of the limiting rod 39. A baffle 311 is fixedly connected to the top of the transmission rod 310. By providing the third connecting rod 31, the rack 32 can be driven to reciprocate when the first turntable 21 rotates. When the rack 32 moves, the gear 34 can be driven to rotate, so that the first bevel gear 35 can be driven to rotate. When the rack 32 and the gear 34 move, the second limiting block 33 can ensure that the rack 32 and the gear 34 remain meshed, avoiding detachment and damage. When the gear 34 rotates, the first bevel gear 35 can be driven to rotate, so that the second bevel gear 36 can be driven to rotate through the first bevel gear 35, and then the second turntable 37 can be driven to rotate. When the second turntable 37 rotates, the third limiting block 38 can be driven to move along the inner cavity of the second limiting groove 312, so that the transmission rod 310 can be driven to reciprocate horizontally, and then the baffle 311 can be driven to block the converging groove 13, avoiding the walnuts in the inner cavity of the pressing shaft 12 falling on the top of the fixed rod 26 during the secondary pressing, resulting in damage. Similarly, when the first turntable 21 runs to a certain position, the rack 32 moves backward, so that the baffle 311 can be driven away from the converging groove 13, and then the next pressing work can be continued.

[0030] During use, the walnuts that have not been fully pressed will fall into the inner cavity of the storage tank 44 through the converging groove 13. After the secondary pressing, they will remain in the inner cavity of the storage tank 44 and cause blockage, as Figure 2As shown in the figure: A cleaning component 4 is arranged at the bottom of the pressing shaft 12. The cleaning component 4 includes a protective shell 41. A push rod 42 is fixedly connected to the inner cavity of the protective shell 41. One end of the push rod 42 is fixedly connected to a scraping plate 43. A material storage groove 44 is arranged on the side of the scraping plate 43. A collection groove 45 is arranged on the side of the material storage groove 44. A filter screen 46 is arranged on the side of the collection groove 45. After the secondary pressing is completed, the push rod 42 is started, so that the output shaft of the push rod 42 can be promoted to push the scraping plate 43 to move forward, and then the walnut residues and residual oil adhering to the bottom inner wall of the material storage groove 44 can be pushed into the inner cavity of the collection groove 45. The oil passes through the filter screen 46 arranged on the side of the collection groove 45, so that it can flow into the oil groove located at the bottom of the pressing shaft 12, and then the problem that the walnut residues are piled up in the inner cavity of the material storage groove 44 and cause blockage can be avoided.

[0031] Working principle:

[0032] As Figures 1-4 shown:

[0033] During use: First, place the collection bucket on the side of the oil tank. Put the prepared walnuts into the inner cavity of the pressing shaft 12 through the feeding port 11. Start the motor, and the output shaft of the motor rotates forward, so as to drive the pressing shaft 12 to initially press the input walnuts. The walnuts after the initial pressing fall into the inner cavity of the storage tank 44 through the converging groove 13. At this time, start the motor arranged on the side of the first disk 21, and the output shaft of the motor rotates forward, so as to drive the first disk 21 to rotate. When the first disk 21 rotates, it can drive the first connecting rod 22 to move along the inner cavity of the first limiting groove 29. When the first connecting rod 22 moves, it can drive the first support plate 25 to move through the second connecting rod 24, so as to promote the fixed rod 26 to move downward. When the pressing head arranged at the bottom of the fixed rod 26 contacts the walnuts, the elastic piece 27 is compressed, so as to absorb the stress. When the elastic piece 27 is compressed to a certain extent, the stress is released, and then the walnuts can be further pressed. At the same time, when the first disk 21 rotates, it can drive the third connecting rod 31 to move, so as to drive the gear 34 to rotate through the rack 32, and then drive the first bevel gear 35 to rotate. When the first bevel gear 35 rotates, it can drive the second disk 37 to rotate through the second bevel gear 36, so as to promote the third limiting block 38 to move along the inner cavity of the second limiting groove 312, and then achieve the effect of driving the transmission rod 310 to move. When the transmission rod 310 moves, it can drive the baffle 311 to move, and can promote the baffle 311 to block the converging groove 13. Similarly, when the first disk 21 runs to a certain position, the rack 32 moves backward, so as to drive the baffle 311 away from the converging groove 13. At the same time, the first connecting rod 22 moves downward, and then the effect of driving the fixed rod 26 to move upward can be achieved. After the secondary pressing is completed, start the push rod 42, so as to promote the output shaft of the push rod 42 to push the scraper 43 forward, and then the walnut residues and residual oil adhering to the bottom inner wall of the storage tank 44 can be pushed into the inner cavity of the collection tank 45. The oil passes through the filter screen 46 arranged on the side of the collection tank 45, and then can flow into the oil tank located at the bottom of the pressing shaft 12.

[0034] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
