Description

Technical Field

[0001] The invention relates to the technical field of edible oil, and in particular to a preparation device for peanut oil. Background Art

[0002] Edible oil, also known as "cooking oil", refers to animal or vegetable oils used in the process of making food. It is liquid at room temperature. Due to the source of raw materials, processing technology and quality, most common edible oils are vegetable oils, including rapeseed oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, etc.; peanut embryos need to be put into a baking oven for baking before oil refining. The purpose of baking is to increase the oil yield of peanuts. In existing baking equipment, the temperature control is not so concerned. When the peanut embryos are baked for a long time, they will be burnt, which will affect the oil yield of peanuts.

[0003] In order to solve the above problems, a Chinese patent with publication number CN214528887U discloses an oil refining equipment for peanut oil production, including a support platform, a heating plate is embedded in the upper surface of the support platform, a motor is fixedly connected to the upper surface of the support platform, a feeding barrel is fixedly connected to the upper surface of the support platform, a spiral rod is rotatably connected inside the feeding barrel, one end of the spiral rod penetrates the inner wall of the feeding barrel and is fixedly connected to the output end of the motor, a feeding port is opened on the surface of the feeding barrel, a feeding seat is connected to the feeding port, and a feeding roller is arranged in the feeding seat; the equipment puts peanuts in a hopper, and then drives the feeding roller and the spiral rod to rotate by rotating the motor, and the feeding roller feeds the same amount of peanuts each time it rotates, and the peanuts fall under the spiral rod and are sent away, which will not cause accumulation, and the feeding is uniform. The roasting time of the peanuts in the feeding barrel is consistent, which ensures that the peanuts will not be burnt due to excessive roasting time.

[0004] The above device has the following problems during actual use: during the movement of the peanuts in the feeding barrel, since the heating plate is fixedly arranged at the bottom of the feeding barrel, most of the heat emitted by the heating plate will act on the lower part of the feeding barrel, and only a small part of the heat can be transferred to the upper part of the feeding barrel, resulting in uneven heat distribution in the feeding barrel, making the roasting efficiency of the peanuts low; and, the small amount of heat emitted by the heating plate takes too long to penetrate into the interior of the peanuts, which leads to uneven heating inside and outside the peanuts, that is, the surface of the peanuts is overheated, the inside of the peanuts is not heated enough, and even the heat cannot fully act on the inside of the peanuts, resulting in poor roasting effect. Summary of the invention

[0005] The invention provides a peanut oil preparation device to solve the problem that the peanuts in the existing oil refining device are heated unevenly inside and outside, thereby reducing the roasting effect.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a peanut oil preparation device, comprising a drying box with a feed port, and also comprising a crushing mechanism arranged in the drying box; the crushing mechanism comprises a worm, a crushing shaft, a worm wheel, a cam, a guide cylinder, a first spring, a through hole opened on the bottom of the drying box, a plurality of crushing knives equidistantly arranged along the length direction of the crushing shaft, a screen plate for sealing the through hole, and a driving component for driving the worm to rotate; the worm and the crushing shaft are both rotatably connected to the drying box; the worm wheel is fixedly connected to the crushing shaft, and the worm wheel is meshed with the worm; the cam is fixedly connected to the worm; the guide cylinder is fixedly connected to the drying box, and the guide cylinder is communicated with the through hole; the screen plate is vertically slidably connected to the inner wall of the guide cylinder, and the cam is against the screen plate; the two ends of the first spring are respectively connected to the screen plate and the inner wall of the guide cylinder; the crushing knife is fixedly connected to the crushing shaft; and also comprises a hot air component for introducing hot air into the drying box.

[0007] The principles and advantages of this solution are:

[0008] 1. The crushing shaft drives the crushing knife to rotate, and the crushing knife can fully crush the peanuts in the drying box, so that the peanuts are broken into several peanut particles with smaller particle sizes, and screened through the screening plate, so that the peanut particles with qualified particle sizes can fall from the screening plate, and the peanut particles with unqualified particle sizes are retained on the screening plate, so that they are crushed by the crushing knife again until the peanut particles have a qualified particle size.

[0009] Through the above movement, under the joint action of the crushing knife and the screening plate, the crushing and screening of the peanuts are completed, so that the particle size of the peanuts becomes smaller, thereby preparing for the subsequent pressing and oil refining, thereby improving the practicability of the device.

[0010] 2. During the period when the peanuts are broken into several peanut particles, the several peanut particles can increase the surface area of ​​the peanuts that are heated, expand the baking range of the hot air component, and enable the hot air component to better bake the peanuts; and, after the peanuts are broken, the thickness of the peanuts will become smaller, and the time for heat to penetrate into the interior of the peanuts will be shortened, thereby improving the baking efficiency of the hot air component, that is, ensuring that the peanuts are heated evenly inside and outside; evenly heated peanuts can ensure that the active ingredients of the peanuts are enhanced, enhance the oil production effect of the peanuts, and improve the oil production quality of the peanuts.

[0011] 3. The cam continuously acts on the screening plate, so that the screening plate can make vertical reciprocating motion; during the vertical reciprocating motion of the screening plate, the peanut particles blocked in the screening plate can be prompted to make vertical reciprocating motion, and finally fall somewhere on the screening plate, thereby changing the position of the peanut particles on the screening plate, thereby ensuring that the peanut particles will not be blocked in the screening holes of the screening plate, enhancing the screening effect of the screening plate, and improving the screening capacity of the screening plate, that is, the screening plate can continuously and efficiently screen the peanut particles; and, during the vertical reciprocating motion of the screening plate, the position of the peanuts on the screening plate can also be changed, prompting the peanuts to be evenly distributed on the screening plate, thereby enhancing the crushing effect of the crushing knife on the peanuts and improving the crushing efficiency of the crushing knife.

[0012] To sum up, through the joint action of the crushing knife, the screening plate and the hot air component, the crushing knife can crush the peanuts multiple times, so that the particle size of the peanuts is gradually reduced; during the crushing of the peanuts, if the particle size of the peanut particles is qualified, the peanut particles will fall out from the screening plate, and the fallen peanut particles have been completely dried, which is convenient for the staff to carry out subsequent collection, storage, pressing and other operations; if the particle size of the peanut particles is unqualified, the peanut particles will be dried and crushed again until the particle size of the peanut particles is qualified; that is, the integration of crushing, roasting, screening and feeding is realized, the work process is simplified, unnecessary work troubles for the staff are saved, and work efficiency is improved.

[0013] Furthermore, it also includes a throwing component; the throwing component includes a throwing block, a connecting block, a second spring, and a throwing part symmetrically arranged on both sides of the crushing shaft along the axial direction of the crushing shaft; the throwing block is vertically slidably connected to the drying box, and the cam is against the throwing block; the connecting block is fixedly connected to the throwing block; the two ends of the second spring are respectively connected to the throwing block and the drying box; the throwing part includes a vertical block, a transverse block, and a plurality of equally divided blocks equidistantly arranged along the length direction of the transverse block; the vertical block is fixedly connected to the connecting block; the transverse block is fixedly connected to the vertical block; and the equally divided block is fixedly connected to the transverse block.

[0014] Under the joint action of the cam, the throwing block, the connecting block, the transverse block and the second spring, the dividing block can make vertical reciprocating motion; during the vertical downward motion of the dividing block, the dividing block extends into the peanuts, so that the peanuts will adhere to the surface of the dividing block; during the vertical upward motion of the dividing block, the dividing block has a certain force, so the peanuts attached to the surface of the dividing block will fly from bottom to top along the height direction of the drying box to both sides of the dividing block, and finally fall on the screening plate; therefore, the peanuts below the crushing knife and the peanuts above the crushing knife are exchanged with each other, so that the peanuts in the height direction of the drying box can directly contact the crushing knife, further enhancing the crushing effect of the crushing knife; that is, through the vertical reciprocating motion of the dividing block, the distribution range of the peanuts can be expanded, so that the peanuts can be evenly distributed in the drying box, further ensuring that the crushing knife can comprehensively and evenly crush the peanuts in the drying box.

[0015] In summary, through the vertical reciprocating motion of the dividing block and the vertical reciprocating motion of the screening plate, the peanuts in the drying box can be evenly distributed in the drying box, ensuring that the peanuts at any position in the drying box can be acted upon by the crushing knife and screened under the action of the screening plate.

[0016] Furthermore, the transverse block is a transverse tube; the equally-dividing block is an equally-dividing tube, which is connected to the transverse tube; the hot air assembly includes a hot air part symmetrically arranged on both sides of the crushing shaft along the axial direction of the crushing shaft; the hot air part includes a hot air heater and a hose; the hot air heater is fixedly connected to the drying box; the two ends of the hose are respectively connected to the hot air heater and the transverse tube; and a number of air outlets are equidistantly opened along the length direction of the equally-dividing tube.

[0017] During the vertical reciprocating motion of the evenly distributing pipe, the hot air flowing out of the hot air generator flows into the horizontal pipe through the hose and finally flows out from the air outlet. Therefore, the hot air can directly act on the inside of the piled peanuts from top to bottom or from bottom to top, ensuring that the inside and outside of the piled peanuts are heated evenly, that is, the roasting time of the peanuts is shortened; and, because the peanuts can change their vertical position under the joint action of the evenly distributing pipe and the screen plate, all the peanuts in the drying box can directly contact with the hot air, further expanding the scope of action of the hot air and enhancing the roasting effect of the hot air.

[0018] Furthermore, it also includes a blowing part arranged in the transverse tube; the blowing part includes blowing units symmetrically arranged on both sides of the transverse tube along the width direction of the transverse tube; the blowing unit includes a rotating shaft, fan blades, and a power unit for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the transverse tube; and the fan blades are fixedly connected to the rotating shaft.

[0019] During the rotation of the rotating shaft, the fan blades rotate synchronously; during the rotation of the fan blades, the fan blades can blow the hot air flowing in the transverse tube, so that the flow rate of the hot air is accelerated, which further ensures that the hot air can flow comprehensively and fully inside and outside the piled peanuts, thereby providing a strong guarantee for the uniform heating of the peanuts and comprehensively enhancing the roasting effect of the peanuts.

[0020] Furthermore, the rotating shaft is a screw; it also includes a linkage unit symmetrically arranged on both sides of the transverse tube along the width direction of the transverse tube; the linkage unit includes a guide rod and a plurality of linkage parts equidistantly arranged along the axial direction of the screw; the guide rod is fixedly connected to the transverse tube; the linkage part includes a nut seat and a linkage block; the nut seat is threadedly connected to the screw, and the nut seat is slidingly connected to the guide rod; the linkage block is fixedly connected to the nut seat, the linkage block is in contact with the inner wall of the transverse tube, and the equalizing tube is located on the motion trajectory of the linkage block.

[0021] When the nut seat makes reciprocating motion along the length direction of the guide rod, the linkage block moves synchronously; during the movement of the linkage block, when the linkage block gradually sticks to the equalizing pipe, the aperture of the air inlet of the equalizing pipe will gradually shrink, that is, by controlling the change of the air inlet aperture of the equalizing pipe, the pressure in the equalizing pipe is increased, so that the hot air has a better roasting effect on the peanuts and the roasting efficiency is higher.

[0022] Furthermore, the spacing between the two sides of the drying box gradually decreases from top to bottom; it also includes a booster part symmetrically arranged on both sides of the crushing shaft along the axial direction of the crushing shaft; the booster part includes a number of booster units equidistantly arranged along the length direction of the transverse tube; the booster unit includes a piston cylinder, a piston block, a third spring, and a wedge block; the piston cylinder is fixedly connected to the inner wall of the equalizing tube; the piston block is slidingly connected to the equalizing tube and the piston cylinder respectively; the two ends of the third spring are respectively connected to the equalizing tube and the piston block; the wedge block is fixedly connected to the piston block, and the wedge block is against the side wall of the drying box; the piston cylinder is respectively connected to an air inlet pipe and an air outlet pipe.

[0023] While the hot air flows into the equalizing pipe, the piston cylinder can pressurize the hot air flowing in the equalizing pipe, ensuring that the hot air flowing out of the air outlet has a faster wind speed and moves a longer distance, that is, further expanding the flow range of the hot air, ensuring that the peanuts in the drying box can be evenly heated inside and outside, so that the peanuts can complete the roasting operation efficiently.

[0024] Furthermore, it also includes a stirring unit symmetrically arranged on both sides of the transverse tube along the width direction of the transverse tube; the stirring unit includes a stirring shaft, a stirring block, and a power part for driving the stirring shaft to rotate; the stirring shaft is rotationally connected to the transverse tube; and the stirring block is fixedly connected to the stirring shaft.

[0025] During the rotation of the stirring shaft, the stirring block rotates synchronously; during the rotation of the stirring block, the stirring block can stir the peanuts from the radial direction, so that the peanuts have a certain fluidity in the radial direction. On the one hand, it can prompt the peanuts to move toward the position of the crushing knife, enhance the crushing effect, and improve the crushing efficiency. On the other hand, it can break up the peanuts, increase the gap between two adjacent peanuts, and enhance the flow effect of hot air, which ensures that the peanuts can be roasted more thoroughly.

[0026] Moreover, since the stirring block can also make vertical reciprocating motion driven by the horizontal tube, on the one hand, it can stir the peanuts in the vertical direction, thereby expanding the stirring range of the peanuts and enhancing the stirring effect of the peanuts; on the other hand, it can make the peanuts have a certain fluidity in the vertical direction, so that the peanuts can continuously change their position in the vertical direction, that is, the stirring block can fully break up the peanuts in the drying box, thereby ensuring the quality of the peanuts after processing.

[0027] Furthermore, it also includes a cleaning part arranged in the guide cylinder; the cleaning part includes a plurality of cleaning units equidistantly arranged along the length direction of the screening plate; the cleaning unit includes a guide block, a slider, a cleaning block, a plurality of brush layers equidistantly arranged along the length direction of the cleaning block, and a driving member for driving the slider to reciprocate along the length direction of the guide block; the guide block is fixedly connected to the guide cylinder, and two adjacent guide blocks are fixedly connected; the slider is slidably connected to the guide block; the cleaning block is fixedly connected to the slider; the brush layer is fixedly connected to the cleaning block, and the free end of the brush layer is against the screening plate.

[0028] During the vertical reciprocating motion of the screening plate, since the free end of the brush layer is against the screening plate, when the screening plate moves vertically downward, the brush layer extends into the screening holes of the screening plate; during the period when the brush layer extends into the screening holes of the screening plate, the brush layer has a certain force, and the brush layer can drive the peanut particles blocked in the screening holes to move upward; during the upward movement of the peanut particles, the peanut particles are no longer blocked in the screening holes of the first screening plate, and finally fall on the screening plate again, preparing for the crushing knife to crush them again.

[0029] The slider drives the brush layer to do reciprocating motion along the length direction of the guide block; during the movement of the brush layer, the brush layer can clean any position along the length direction of the screen plate, that is, the action range of the brush layer is expanded, ensuring that the screen plate is cleaned more comprehensively and fully.

[0030] To sum up, through the reciprocating motion of the bristle layer along the length direction of the guide block and the vertical reciprocating motion of the screen plate, it is ensured that the screening holes at any position on the screen plate can be cleaned, that is, the screening holes of the screen plate are no longer blocked by peanut particles, so that the screen plate is in a high-efficiency screening state for a long time, thereby enhancing the screening effect and improving the screening efficiency.

[0031] Furthermore, the power unit includes a first gear and a first rack; the first gear is fixedly connected to the screw rod; the first rack is fixedly connected to the drying box; and the first gear is meshed with the first rack.

[0032] During the vertical reciprocating motion of the screw, the first gear moves synchronously; during the motion of the first gear, the first gear is engaged with the first rack, thereby rotating the first gear; during the rotation of the first gear, the screw rotates synchronously; therefore, the screw can rotate while it reciprocates vertically.

[0033] Furthermore, the power part includes an auxiliary shaft, a first bevel gear, a second bevel gear, and a belt; the auxiliary shaft is rotatably connected to the transverse tube; the first bevel gear is fixedly connected to the stirring shaft; the second bevel gear is fixedly connected to the auxiliary shaft, and the first bevel gear is meshed with the second bevel gear; and both ends of the belt are respectively sleeved between the screw and the auxiliary shaft.

[0034] During the rotation of the screw, the screw drives the auxiliary shaft to rotate synchronously through the belt; during the rotation of the auxiliary shaft, the second bevel gear rotates synchronously; during the rotation of the second bevel gear, the first bevel gear rotates due to the meshing of the first bevel gear and the second bevel gear; during the rotation of the first bevel gear, the stirring shaft rotates synchronously.

[0055] The staff puts the peanuts into the drying box 1 through the feed port, and after the peanuts are placed, the motor 9 is started to drive the worm 2 to rotate through the output shaft of the motor 9; during the rotation of the worm 2, the worm 2 is engaged with the worm wheel 4, so that the worm wheel 4 rotates; during the rotation of the worm wheel 4, the crushing shaft 3 rotates synchronously; during the rotation of the crushing shaft 3, the crushing knife 8 rotates synchronously; during the rotation of the crushing knife 8, the crushing knife 8 can fully crush the peanuts in the drying box 1, so that the peanuts are broken into a number of peanut particles with smaller particle sizes, and are screened through the screening plate 44, so that the peanut particles with qualified particle sizes can fall from the screening plate 44, and the peanut particles with unqualified particle sizes are retained on the screening plate 44, so that they are crushed by the crushing knife 8 again until the peanut particles have a qualified particle size.

[0059] During the vertical reciprocating motion of the screening plate 44, the peanut particles blocked in the screening plate 44 can be forced to make vertical reciprocating motion, and finally fall somewhere on the screening plate 44, thereby changing the position of the peanut particles on the screening plate 44, thereby ensuring that the peanut particles will not be blocked in the screening holes of the screening plate 44, thereby enhancing the screening effect of the screening plate 44, and improving the screening capacity of the screening plate 44, that is, the screening plate 44 can continuously and efficiently screen the peanut particles; and, during the vertical reciprocating motion of the screening plate 44, the position of the peanuts on the screening plate 44 can also be changed, so that the peanuts are evenly distributed on the screening plate 44, thereby enhancing the crushing effect of the crushing knife 8 on the peanuts and improving the crushing efficiency of the crushing knife 8.

[0060] To sum up, through the joint action of the crushing knife 8, the screening plate 44 and the hot air generator 16, the crushing knife 8 can crush the peanuts multiple times, so that the particle size of the peanuts is gradually reduced; during the crushing of the peanuts, if the particle size of the peanut particles is qualified, the peanut particles will fall out from the screening plate 44, and the fallen peanut particles have been completely dried, which is convenient for the staff to carry out subsequent collection, storage, pressing and other operations; if the particle size of the peanut particles is unqualified, the peanut particles will be dried and crushed again until the particle size of the peanut particles is qualified; that is, the integration of crushing, roasting, screening and feeding operations is realized, the work process is simplified, unnecessary work troubles of the staff are saved, and work efficiency is improved.

[0061] During the rotation of the cam 5, when the raised portion of the cam 5 abuts against the throwing block 10, the cam 5 moves vertically upward, and the second spring 12 is compressed. When the raised portion of the cam 5 no longer abuts against the throwing block 10, the throwing block 10 is reset under the action of the second spring 12, and the throwing block 10 moves vertically downward; therefore, the throwing block 10 can perform vertical reciprocating motion.

[0062] During the vertical reciprocating motion of the throwing block 10, the equalizing tube can move synchronously with the throwing block 10 under the joint action of the connecting block 11 and the vertical block 13; during the vertical downward motion of the equalizing tube, the equalizing tube extends into the peanuts, so that the peanuts will adhere to the surface of the equalizing tube; during the vertical upward motion of the equalizing tube, the equalizing tube has a certain force, so the peanuts attached to the surface of the equalizing tube will fly from bottom to top along the height direction of the drying box 1 to both sides of the equalizing tube, and finally fall on the screening plate 44; therefore, the peanuts below the crushing knife 8 and the peanuts above the crushing knife 8 are exchanged with each other, so that the peanuts in the height direction of the drying box 1 can directly contact the crushing knife 8, further enhancing the crushing effect of the crushing knife 8; that is, through the vertical reciprocating motion of the equalizing tube, the distribution range of the peanuts can be expanded, so that the peanuts can be evenly distributed in the drying box 1, further ensuring that the crushing knife 8 can comprehensively and evenly crush the peanuts in the drying box 1.

[0063] To sum up, through the vertical reciprocating motion of the equalizing pipe and the vertical reciprocating motion of the screening plate 44, the peanuts in the drying box 1 can be evenly distributed in the drying box 1, ensuring that the peanuts at any position in the drying box 1 can be acted upon by the crushing knife 8 and screened under the action of the screening plate 44.

[0064] During the vertical reciprocating motion of the evenly distributing pipe, the hot air flowing out of the hot air device 16 flows into the transverse pipe through the hose 17, and finally flows out from the air outlet 18. Therefore, the hot air can directly act on the inside of the piled peanuts from top to bottom or from bottom to top, ensuring that the inside and outside of the piled peanuts are heated evenly, that is, the roasting time of the peanuts is shortened; and, because the peanuts can change their vertical position under the joint action of the evenly distributing pipe and the sieve plate 44, all the peanuts in the drying box 1 can directly contact with the hot air, further expanding the scope of action of the hot air and enhancing the roasting effect of the hot air.

[0065] During the vertical reciprocating motion of the transverse tube, the screw moves synchronously; during the motion of the screw, the first gear 34 moves synchronously; during the motion of the first gear 34, the first gear 34 is engaged with the first rack 35, thereby rotating; during the rotation of the first gear 34, the screw rotates synchronously; therefore, the screw can rotate while it reciprocates vertically.

[0066] During the rotation of the screw, the fan blades 20 rotate synchronously; during the rotation of the fan blades 20, the fan blades 20 can blow the hot air flowing in the transverse tube, so that the flow rate of the hot air is accelerated, which further ensures that the hot air can flow comprehensively and fully inside and outside the piled peanuts, thereby providing a strong guarantee for the uniform heating of the peanuts and comprehensively enhancing the roasting effect of the peanuts.

[0067] During the rotation of the screw, the nut seat 22 can make reciprocating motion along the length direction of the guide rod 21, and the linkage block 23 moves synchronously; during the movement of the linkage block 23, when the linkage block 23 and the equalizing tube gradually stick together, the aperture of the air inlet of the equalizing tube will gradually shrink, that is, by controlling the change of the air inlet aperture of the equalizing tube, the pressure in the equalizing tube is increased, so that the hot air can better roast the peanuts and the roasting efficiency is higher.

[0068] During the period when the hot air flows in the equalizing pipe and the equalizing pipe moves vertically upward, the wedge block 27 drives the piston block 25 away from the air inlet pipe along the length direction of the piston cylinder 24 under the action of the inclined surface of the drying box 1, and the third spring 26 is compressed, so that the piston block 25 exhausts air, and the hot air flows into the piston cylinder 24 along the air inlet pipe and is temporarily stored; when the equalizing pipe moves vertically upward, the piston block 25 is reset under the action of the third spring 26, and the piston block 25 approaches the air inlet pipe along the length direction of the piston cylinder 24, so that the piston block 25 exhausts air, and the hot air stored in the piston cylinder 24 is discharged along the air outlet pipe; therefore, the piston block 25 can make reciprocating motion along the length direction of the piston cylinder 24.

[0069] Through the above movement, the piston block 25 can pressurize the hot air flowing in the distribution pipe, ensuring that the hot air flowing out of the air outlet 18 has a faster wind speed and moves a longer distance, that is, the flow range of the hot air is further expanded, ensuring that the peanuts in the drying box 1 can be evenly heated inside and outside, so that the peanuts can be roasted efficiently.

[0070] During the rotation of the screw, the screw drives the auxiliary shaft 36 to rotate synchronously through the belt 39; during the rotation of the auxiliary shaft 36, the second bevel gear 38 rotates synchronously; during the rotation of the second bevel gear 38, the first bevel gear 37 rotates due to the meshing of the first bevel gear 37 with the second bevel gear 38; during the rotation of the first bevel gear 37, the stirring shaft 28 rotates synchronously.

[0071] During the rotation of the stirring shaft 28, the stirring block 29 rotates synchronously; during the rotation of the stirring block 29, the stirring block 29 can stir the peanuts from the radial direction, so that the peanuts have a certain fluidity in the radial direction. On the one hand, it can promote the peanuts to move toward the position of the crushing knife 8, enhance the crushing effect, and improve the crushing efficiency. On the other hand, it can break up the peanuts, increase the gap between two adjacent peanuts, and enhance the flow effect of the hot air, that is, ensure that the peanuts can be roasted more thoroughly.

[0072] Furthermore, since the stirring block 29 can also make vertical reciprocating motion driven by the horizontal tube, on the one hand, the peanuts can be stirred in the vertical direction, thereby expanding the stirring range of the peanuts and enhancing the stirring effect of the peanuts; on the other hand, the peanuts can have a certain fluidity in the vertical direction, so that the peanuts can continuously change their position in the vertical direction, that is, the stirring block 29 can fully break up the peanuts in the drying box 1, thereby ensuring the quality of the peanuts after processing.

[0073] During the vertical reciprocating motion of the screening plate 44, the second rack 43 moves synchronously; during the movement of the second rack 43, the second rack 43 is meshed with the second gear 41, so that the second gear 41 rotates; during the rotation of the second gear 41, the third gear 42 rotates synchronously; during the rotation of the third gear 42, the third gear 42 is meshed with the third rack, so that the third rack can reciprocate along the length direction of the guide block 30.

[0074] The screening plate 44 reciprocates vertically. Since the free end of the brush layer 33 abuts against the screening plate 44, when the screening plate 44 moves vertically downward, the brush layer 33 extends into the screening holes of the screening plate 44; during the period when the brush layer 33 extends into the screening holes of the screening plate 44, the brush layer 33 has a certain force, and the brush layer 33 can drive the peanut particles blocked in the screening holes to move upward; during the upward movement of the peanut particles, the peanut particles are no longer blocked in the screening holes of the first screening plate 44, and finally fall onto the screening plate 44 again, preparing for the crushing knife 8 to crush them again.

[0075] During the movement of the third rack, the cleaning block 32 moves synchronously; during the movement of the cleaning block 32, the bristle layer 33 reciprocates along the length direction of the guide block 30; during the movement of the bristle layer 33, the bristle layer 33 can clean any position in the length direction of the screen plate 44, that is, the scope of action of the bristle layer 33 is expanded, ensuring that the screen plate 44 is cleaned more comprehensively and fully.

[0076] To sum up, through the reciprocating motion of the bristle layer 33 along the length direction of the guide block 30 and the vertical reciprocating motion of the screen plate 44, it is ensured that the screening holes at any position on the screen plate 44 can be cleaned, that is, the screening holes of the screen plate 44 are no longer blocked by peanut particles, so that the screen plate 44 is in a high-efficiency screening state for a long time, thereby enhancing the screening effect and improving the screening efficiency.
