Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rapeseed oil extraction, in particular to a rapeseed selection device and use method. BACKGROUND

[0002] Rapeseed oil extraction is a common plant oil extraction process, mainly using rapeseed as raw material. Rapeseed is rich in oil, usually containing 35-45% oil. The oil extraction process mainly includes cleaning, crushing, steaming and frying, rolling, pressing and other steps. The extracted oil is filtered, precipitated and treated to obtain golden yellow, nutrient-rich rapeseed oil.

[0003] Usually, the rapeseed is selected before oil extraction to remove impurities, shriveled grains and moldy grains. The purity of the selected rapeseed is higher, and the impurity content is greatly reduced, which not only helps to improve the oil extraction efficiency, but also improves the quality and taste of the oil. The selection process can also remove diseased and insect-infested grains, reducing the risk of damage and deterioration during storage.

[0004] Broken rapeseed can cause internal structure damage, oil cell rupture, and partial oil loss or oxidation before processing, resulting in reduced oil yield. Broken rapeseed is more susceptible to microbial infection, leading to oil spoilage or off-flavor. In addition, broken grains may release more free fatty acids during processing, increasing the acid value of the oil and reducing the quality of the oil.

[0015] A use method of the rapeseed selection device, comprising the following steps:

[0016] S1, the required selected rapeseed is input from the feed guide slot into the installation shell, and the small rapeseed falls directly into the installation shell from the gap of the rear roller after passing through the rear roller. The complete small rapeseed is output into the side collection box for collection by the driving push plate and the screening fan working alternately. The incomplete small rapeseed directly falls into the storage shell. The rapeseed on the top is blown off into the storage shell by the screening fan when passing through the inner support block. The larger rapeseed continues to advance to the front roller, crushes the incomplete rapeseed, and scrapes the rapeseed shell and oil on the surface by the scraping knife to select the complete large particles in the rapeseed;

[0017] S2, the driving motor is started to drive the driving bevel gear to rotate. The driving bevel gear top is engaged with the shaft bevel gear and the roller bevel gear respectively. The rotation directions of the shaft bevel gear and the roller bevel gear are opposite. The roller bevel gear transmits the rotation to the roller driving engagement gear and drives the roller driving engagement gear on the other side to rotate. The two roller driving engagement gears drive the two front rollers to rotate respectively. When the surface of the front roller passes through the incomplete rapeseed, the groove of the front roller will be stuck on the surface of the rapeseed and pull it down and crush it. The shaft bevel gear drives the driving shaft to rotate. The rotation direction of the driving shaft on this side is opposite to that of the roller bevel gear. The driving shaft is not connected with the intermediate front roller, the roller bevel gear, the roller driven engagement gear and other components, but is directly connected with the shaft engagement gear on the other side to drive it to rotate. The shaft engagement gear drives the driven input bevel gear to rotate. The rotation is transmitted to the roller driven engagement gear through the driven intermediate bevel gear and the driven output bevel gear. The rotation direction of the roller driven engagement gear is opposite to that of the driving shaft. The roller driven engagement gear drives the rear roller to rotate through the two roller driven engagement gears. The front roller and the rear roller on each side are separated in the middle, but the rotation directions are the same. The front roller and the rear roller on both sides cooperate to crush the incomplete rapeseed and output it to the storage shell.

[0018] S3, the driving shaft is not connected with the intermediate front roller, the roller bevel gear, the roller driven engagement gear and other components, but is directly connected with the shaft engagement gear on the other side to drive it to rotate. There are also two shaft engagement gears, and the other shaft engagement gear drives the driven shaft to rotate. The driving shaft and the driven shaft drive the screening fan to rotate. The two screening fans are different by one hundred and eighty degrees. When the screening fan on one side blows downward, the screening fan on the other side blows upward. The wind of the downward blowing screening fan is guided to the inner support block through the air guide groove, so that the rapeseed and the empty shell passing through it are subjected to the upward wind force and enter the air duct composed of the top guide block and the side baffle. The upward blowing screening fan on the other side blows air to both sides in the upward direction in the air duct, drives the empty shell in the air duct into the storage shell, and the rotation directions of the screening fan and the front roller and the rear roller on this side are opposite. In this way, the incomplete shell is crushed from the front roller and the rear roller and output downward to the storage shell, while the empty shell is blown by the screening fan and output upward to the different compartments of the storage shell, which separates the incomplete rapeseed and the rapeseed empty shell.

[0019] S4, the process of rotating the driven shaft drives the surface cam column to rotate, the cam column drives the reciprocating arm to realize reciprocating movement and drives the driven push plate to reciprocate, the two sides of the driven push plate are connected by the push arm, when one side of the driven push plate moves, the other side of the driven push plate will be pushed by the push arm, so that the two driven push plates are always in opposite positions, and each driven push plate pulls the blocking plate on the other side through the traction rope, when the driven push plate moves away from the blocking plate, the blocking plate on the same side of the driven push plate will be lowered, so that when the incomplete small particles and the complete small particles fall from the gap of the rear roller, they will fall into the inner guide plate and continue to fall, and roll to the two driven push plates in the fixed chute, the two sides of the screening fan will rotate to output wind force alternately downward, and the complete small particles on the driven push plate will be blown and rolled to the other side of the side collecting box, while the surface damaged rapeseed cannot be blown and waits to be pushed into the storage shell by the fixed chute after the driven push plate is collected, and at this time the blocking plate on this side is lowered, so that no new rapeseed enters the driven push plate, realizing the effect of alternately screening small rapeseed according to the rotation state of the screening fan.

[0020] Compared with the prior art, the beneficial effects of the present application are:

[0021] In the present application, through the setting of the driving mechanism, the power of a single motor can be distributed to multiple working components such as the front roller, the rear roller, the screening fan, etc., ensuring that the components work cooperatively, controlling the rolling and winnowing of the rolling and winnowing mechanism, so that the rolled rapeseed and the winnowed empty hulls are stored in different areas for differentiation, and through multiple stages of screening, the purity of the finally collected rapeseed is high and the impurities are few.

[0022] In the present application, through the cooperation of the driving mechanism and the rolling and winnowing mechanism, through the dual action of rolling and winnowing, incomplete rapeseed and empty hulls can be effectively separated, the purity of the selected rapeseed is improved, mechanical rolling and air screening are combined, the screening efficiency is greatly improved, and the labor intensity of manual screening is reduced.

[0023] In the present application, through the cooperation of the rolling and winnowing mechanism and the secondary screening mechanism, small rapeseed is further screened, and through the multiple actions of mechanical rolling, air screening and secondary screening, complete rapeseed, incomplete rapeseed and empty hulls can be efficiently separated.

[0059] S1, the required rapeseed is input from the feed guide groove 2 into the installation housing 1, and the small rapeseed falls directly into the installation housing 1 from the gap of the rear roller 511 after passing through the rear roller 511. The complete small rapeseed is output into the side collection box 3 for collection by the alternating work of the driven push plate 72 and the screening fan 52. The incomplete small rapeseed directly falls into the storage housing 11. The rapeseed on the top is blown into the storage housing 11 by the screening fan 52 when passing through the inner support 532. The larger rapeseed continues to move to the front roller 51, crushes the incomplete rapeseed, and scrapes the rapeseed shell and oil on the surface by the scraping knife 62 to select the complete large particles in the rapeseed.

[0060] S2, the driving motor 41 is started to drive the driving bevel gear 411 to rotate. The driving bevel gear 411 top is engaged with the shaft bevel gear 42 and the roller bevel gear 43 respectively. The rotation directions of the shaft bevel gear 42 and the roller bevel gear 43 are opposite. The roller bevel gear 43 transmits the rotation to the roller driving engagement gear 431 and drives the roller driving engagement gear 431 on the other side to rotate. The two roller driving engagement gears 431 drive the two front rollers 51 to rotate respectively. When the surface of the front roller 51 passes through the incomplete rapeseed, the recess of the front roller 51 will clamp the surface of the rapeseed and pull it down and crush it. The shaft bevel gear 42 drives the driving shaft 421 to rotate. The rotation direction of the driving shaft 421 on the side of the roller bevel gear 43 is opposite. The driving shaft 421 is not connected with the intermediate front roller 51, the roller bevel gear 43, the roller driven engagement gear 4421, etc. It is directly connected with the shaft engagement gear 422 on the other side to drive it to rotate. The shaft engagement gear 422 drives the driven input bevel gear 44 to rotate. The rotation is transmitted to the roller driven engagement gear 4421 through the driven intermediate bevel gear 441 and the driven output bevel gear 442. The rotation direction of the roller driven engagement gear 4421 is opposite to that of the driving shaft 421. The two roller driven engagement gears 4421 drive the rear roller 511 to rotate. The front roller 51 and the rear roller 511 on each side are separated in the middle, but the rotation directions are the same. The front roller 51 and the rear roller 511 on both sides cooperate to crush the incomplete rapeseed and output it to the storage housing 11.​

[0061] S3, the driving shaft 421 is not connected with the intermediate front roller 51, the roller bevel gear 43, the roller driven gear 4421 and other components, and is directly connected with the shaft engaging gear 422 on the other side to drive the rotation of the shaft engaging gear 422. The shaft engaging gear 422 also has two, and the other shaft engaging gear 422 drives the rotation of the driven shaft 4221. The driving shaft 421 and the driven shaft 4221 drive the rotation of the screening fan 52. The two screening fans 52 are different by one hundred and eighty degrees. When the screening fan 52 on one side blows downward, the screening fan 52 on the other side blows upward. The wind of the screening fan 52 blowing downward is guided to the inner support block 532 through the air guide groove 531, so that the rapeseed and the empty shell passing through are subjected to the upward wind force, and enter the air duct composed of the top guide block 54 and the side baffle 541. The screening fan 52 on the other side blows upward and blows air to both sides in the upward direction in the air duct, so as to drive the empty shell in the air duct into the accommodation shell 11. The screening fan 52 is opposite to the rotation direction of the front roller 51 and the rear roller 511 on the side. In this way, the incomplete empty shell is crushed from the front roller 51 and the rear roller 511 and output downward to the accommodation shell 11, and the empty shell is blown by the screening fan 52 and output upward to different compartments of the accommodation shell 11, so as to separate the incomplete rapeseed and the rapeseed empty shell;

[0062] S4, the driven shaft 4221 drives the rotation of the surface cam column 71 during the rotation. The cam column 71 drives the reciprocating arm 711 to realize reciprocating movement and drives the driven push plate 72 to reciprocate. The two driven push plates 72 are connected by the pushing arm 73. When one side of the driven push plate 72 moves, the other side of the driven push plate 72 will be pushed by the pushing arm 73, so that the two driven push plates 72 are always in opposite positions. Each driven push plate 72 pulls the blocking plate 752 on the other side through the traction rope 75. When the driven push plate 72 moves away from the blocking plate 752, the blocking plate 752 on the same side as the driven push plate 72 will be lowered. In this way, after the incomplete small particles and the complete small particles fall from the gap of the rear roller 511, they will fall into the inner connecting plate 741 and continue to fall, and roll to the two driven push plates 72 through the fixed chute 74. The two screening fans 52 will rotate to output wind force downward alternately, and blow and roll the complete small particle rapeseed on the driven push plate 72 to the other side of the side collecting box 3. The surface damaged rapeseed cannot be blown and is pushed into the accommodation shell 11 by the fixed chute 74 after the driven push plate 72 is retracted. At this time, the blocking plate 752 on the side is lowered, and no new rapeseed enters the driven push plate 72, so as to realize the effect of alternately screening small particle rapeseed according to the rotation state of the screening fan 52.
