Description

Technical Field

[0001] The invention relates to the technical field of rapeseed crushing, and in particular to a rapeseed pre-crushing device for rapeseed oil processing. Background Art

[0002] Rapeseed, also known as Brassica rapa, is the seed of the cruciferous crop rapeseed. Rapeseed has long pods, many pods, and full grains. The oil content in rapeseed is 37.5%-46.3%. The oil content varies slightly depending on the type of rapeseed. It is one of China's major oil crops and nectar crops, and its seeds are one of the main varieties of raw materials for making oil.

[0003] At present, when traditional rapeseed is used to press rapeseed oil, the harvested rapeseed is first dried, and then the rapeseed is passed through a screening machine to remove impurities. After the impurities are removed, the rapeseed is moved to a grinder to be crushed, and the crushed rapeseed is transported to a stir-frying furnace for high-temperature stir-frying. After stir-frying, it is then pressed through a press to squeeze out the rapeseed oil. The squeezed rapeseed oil can enter the market after hydration and impurity removal, storage sedimentation, constant temperature refining and refrigerated storage.

[0004] Since the screening and crushing of rapeseed are completed independently, and the rapeseed can only be transported to the next process after the previous equipment has processed the rapeseed, this not only increases the labor of the staff, but also makes the equipment investment high and occupies a large area.

[0050] Embodiment 3

[0051] like Figure 1-Figure 9 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0052] The material discharge assembly 3 includes a material discharge hopper 31 and a spline 32. The top surface of the crushing box 21 is fixedly connected to the material discharge hopper 31. The inner cavity of the material discharge hopper 31 is fixedly connected to the material discharge rack 33.

[0053] The double-shaft motor in the feeding assembly 3 drives the spline 32 to rotate, thereby driving the feeding rod 34 to rotate, and also driving the auger blade 35 to rotate, so that uniform feeding can be achieved, which is convenient for better crushing of the rapeseed in the later stage.

[0054] The working principle and use process of the present invention:

[0055] In use:

[0056] When in use, first, put the rapeseed to be cleaned into the hopper 62. After putting it in, move the sealing plate 64 so that the sealing plate 64 slides in the sealing groove 63 to change the size of the discharge port so that the rapeseed can be discharged evenly. After adjusting the sealing plate 64, screw the positioning screw 67 so that one end of the positioning screw 67 contacts one end of the inner cavity of the track 65, and the connecting rod 66 and the sealing plate 64 can be fixed to prevent the sealing plate 64 from moving and changing the size of the discharge port.

[0057] The vibration motor 45 is started and works. Under the action of the reciprocating spring rod 43, the screening bucket 41 is driven to vibrate reciprocatingly up and down. At this time, the rapeseeds dropped on the upper part of the first filter plate 461 will drop onto the second filter plate 462 under the action of vibration, and the larger impurities will be discharged from the discharge plate 464 at one end of the first filter plate 461. When discharging, in order to prevent the rapeseeds from falling from one end of the first filter plate 461, the intercepting rod 465 is used to slow down the discharge time of the impurities, so that the separation is more thorough. The rapeseeds dropped on the second filter plate 462 will drop from the second filter plate 462 to the slag discharge plate 463 under the action of vibration, and the rapeseeds will drop from the gathering hopper 466 into the dust removal cylinder 51.

[0058] Start the double-shaft motor 56, the bag dust collector 582, the blower 541 and the heating box 542. When the rapeseed falls into the dust removal cylinder 51, the first gathering ring 52 causes the rapeseed to fall into the filter basin 572. At this time, the double-shaft motor 56 drives the centrifugal shaft 571, the filter basin 572 and the disc 573 to rotate. When the filter basin 572 rotates, the rapeseed inside can be thrown out to the surroundings. When being thrown out, the purpose is to separate the rapeseed from impurities. When the rapeseed is thrown out, the blower inputs the outside air into the heating box 542, and after heating, The air will be input into the hot air ring 545 under the action of the hot air pipe 544, and finally, be discharged into the dust removal cylinder 51. At this time, the hot air moves upward, which heats the rapeseed on the one hand, and on the other hand, makes it easier to remove the rapeseed and the surface dust. When the hot air moves upward with the dust, it drives the dust to the dust suction plate 581. At this time, the bag dust collector 582 works and can suck the dust from the dust suction plate 581 into the bag dust collector 582, thereby removing the dust. When the rapeseed is thrown out, it will fall into the lower hopper 31 under the action of the second gathering ring 53.

[0059] When the dual-axis motor 56 is working, it will drive the spline 32 to rotate. When the spline 32 rotates, it will drive the discharge rod 34 to rotate, thereby driving the auger blade 35 to rotate. When the auger blade 35 rotates, the material in the discharge hopper 31 can be evenly output to between the first crushing roller 227 and the second crushing roller 229.

[0060] At this time, the first drive motor 223 and the second drive motor 226 are started respectively. When the first drive motor 223 and the second drive motor 226 are working, they will drive the first crushing roller 227 and the second crushing roller 229 to rotate respectively. When the first crushing roller 227 and the second crushing roller 229 rotate, the rapeseed can be initially squeezed and crushed, and the squeezed and crushed rapeseed will fall into the arc filter 25. At this time, the crushing motor 261 is started, and the crushing motor 261 will drive the crushing rod 262 to rotate. When the crushing rod 262 rotates, it will drive the mouth frame 263 and the crushing knife 264 to rotate. When the mouth frame 263 rotates, the arc filter 25 can be cleaned, and the rotation of the crushing knife 264 will start to crush the rapeseed in the arc filter 25, and the crushed rapeseed will fall from the arc filter 25.

[0061] When it is necessary to adjust the degree of crushing according to the squeezing degree, the movable threaded rod 225 can be rotated, and the movable threaded rod 225 will drive the movable plate 224 to move, thereby driving the first crushing roller 227 to move, so as to adjust the distance between the first crushing roller 227 and the second crushing roller 229, so as to crush the rapeseed into particles of different sizes in the later stage.
