When in work: the controller is started, the vegetable seeds are put into the charging hopper 4, hot air is blown in through the air inlet holes 41 on the side wall of the charging hopper 4, the temperature of the vegetable seeds in the charging hopper 4 is maintained, meanwhile, the vegetable seed residues in the charging hopper 4 are blown up, the impurities of the vegetable seeds entering the press barrel 2 are reduced, and the working efficiency of the equipment is improved; the gear set 6 drives the wheel disc 61 to rotate intermittently, the wheel disc 61 drives the two steel wire ropes 7 to twist and press the hose 5 when rotating, the pipe diameter of the hose 5 changes, the torsional restoring force of the steel wire ropes 7 enables the wheel disc 61 to reset reversely when the wheel disc 61 rotates intermittently, the vibration and the pipe diameter of the hose 5 change, the blockage of the rapeseed in a feeding channel is avoided, and the oil extraction efficiency is improved; the lever 9 is driven to rotate by the wind power of the hot air blower 10, so that the sliding block 8 slides to one end far away from the hose 5, the spring is pressed tightly, the wind power of the hot air blower 10 is weakened, the spring bounces, the sliding block 8 slides to one end close to the hose 5, the protrusion 81 impacts the hose 5 to vibrate the hose 5, the wind power of the hot air blower 10 is enhanced, the lever 9 drives the sliding block 8 to slide and reset to one end far away from the hose 5, and the reciprocating manner is carried out, the feeding rate of the rape seeds in the hose channel is balanced by the vibration of the hose, and the oil pressing efficiency is; meanwhile, hot air is guided to be blown into the machine shell 1 through the arc-shaped upper lever arm 91, so that a heat insulation effect is provided for the hose 5 and the squeezing barrel 2 in the machine shell 1, and the influence of temperature difference between the inside and the outside of the hose 5 and the squeezing barrel 2 is reduced; the force application effect of the lever 9 is enlarged by the long and short lever arms formed by the lower lever arms 92 of the lever 9 and two contact points of the sliding block 8, and the transmission of the lever 9 is facilitated; and the rapeseed enters the squeezing barrel 2 to be squeezed to obtain squeezed oil, and the squeezed oil is filtered to obtain the finished oil.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
