In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1-3, an embodiment of the present invention provides a flax threshing device 100, which comprises a frame 1, a rolling device and a winnowing mechanism. Wherein, the frame 1 can be a box body with a hollow structure. The frame 1 is provided with a feed inlet, and a chopper 2 for chopping flax heads is arranged at the feed inlet. The fodder chopper 2 is rotatably connected with the frame 1, and the fodder chopper 2 can be in transmission connection with the motor through belt transmission. The rolling device is arranged below the hand hay cutter 2 and is used for rolling the flax heads. The rolling device comprises an upper grinding disc 3, a lower grinding disc 4 and a driving mechanism. The upper grinding disc 3 and the lower grinding disc 4 are coaxially arranged with a gap therebetween. One of the upper grinding disc 3 and the lower grinding disc 4 is rotatably connected with the machine frame 1, for example, as shown in fig. 1, the upper grinding disc 3 is rotatably connected with the machine frame 1, and optionally, the upper grinding disc 3 is rotatably connected with the machine frame 1 through a bearing. The center of the upper millstone 3 is provided with a through hole for the flax head to enter between the upper millstone 3 and the lower millstone 4, and the lower millstone 4 is provided with a blanking hole for the flax granules to pass through and fall down. The driving mechanism is used for driving the upper grinding disc 3 or the lower grinding disc 4 to rotate. For example, a peripheral gear is arranged on the outer peripheral wall of the upper grinding disc 3, and the driving mechanism comprises a driving gear which is rotatably connected with the frame 1 and is in gear engagement with the upper grinding disc 3 and a motor which is in transmission connection with the driving gear. The motor can drive the driving gear to rotate through chain transmission, belt transmission and gear transmission, and the driving gear can drive the upper grinding disc 3 to rotate at the same time. And the winnowing mechanism is arranged below the rolling device and comprises a fan 5 arranged on one side of a blanking path of the rolling device and a receiving pipe 6, wherein the first end pipe orifice of the receiving pipe is opposite to the fan 5.
The specific using process is as follows: when the flax head crusher is used, flax is fed from a feed inlet, the flax head can be cut by the fodder chopper 2, the cut flax head falls onto the upper grinding disc 3 and enters between the upper grinding disc 3 and the lower grinding disc 4 through the through hole on the upper grinding disc 3, the upper grinding disc 3 and the lower grinding disc 4 rotate relatively under the driving of the driving mechanism, the fallen flax grains fall through the blanking hole on the lower grinding disc 4, and the flax head with larger volume is rolled between the upper grinding disc 3 and the lower grinding disc 4 and finally becomes crushed and falls. Through setting up the blanking hole for flaxseed grain and flaxseed skin both can fall from the blanking hole, can fall from the circumference border of mill 4 down again, thereby accelerate the efficiency of flaxseed grain whereabouts, avoid taking place the jam. The fan 5 of the air separation mechanism works simultaneously, the flax peels can be blown into the receiving pipe 6 to be discharged, and the fallen flax seeds are collected.
In some embodiments, the flax threshing device 100 further comprises a collection hopper 7. The upper end of the aggregate bin 7 is provided with an opening which is wrapped on the lower part of the rolling device. The receiving pipe 6 and the fan 5 are respectively arranged on two sides of the lower end opening of the collecting hopper 7. Can collect the discharged sesame grain of rolling machine and sesame skin through collecting hopper 7 to winnowing mechanism carries out the selection by winnowing.
Referring to fig. 1, in some embodiments, receiving pipe 6 is horizontally disposed, and a discharge opening is formed in the bottom wall of receiving pipe 6. Be equipped with first end in the receiving tube 6 and be connected with the 6 diapire of receiving tube, the second end is to keeping away from the first baffle 8 of the orificial direction slope of the first end of receiving tube 6, and 8 first ends of first baffle are close to the bin outlet. The outer wall of the receiving pipe 6 is provided with a storage box 9, and the storage box 9 is communicated with the discharge port. The discharge openings, the first baffle 8 and the material storage boxes 9 are the same in number and are in one-to-one correspondence. So set up, when fan 5 insufflates the receiving tube 6 with the flax skin in, probably have partial flax seed and insufflate in receiving tube 6 simultaneously, keep off the speed reduction through 8 check of first baffle, keep off the relatively heavier flax seed of quality down, in the flax seed slided down along first baffle 8 and finally enters into storage case 9 through the bin outlet, and the flax skin can continue to discharge under wind-force effect.
In some embodiments, the number of the first baffle plates 8 is at least two, and a second baffle plate 10 is disposed between two first baffle plates 8, wherein the first end of the second baffle plate is connected to the top wall of the receiving pipe 6, and the second end of the second baffle plate is inclined away from the nozzle of the first end of the receiving pipe 6. With the arrangement, the flax peels in the receiving pipe 6 can be screened twice, so that the recovery rate of the flax seeds is improved. The second baffle 10 can further decelerate the flax seeds so that the flax seeds fall down, while the flax skin is lighter and still discharges with the wind.
In some embodiments, the bottom of the storage box 9 is provided with an opening and a cover plate 11 for closing and opening the opening, the cover plate 11 is rotatably connected with the storage box 9, and the storage box further comprises a closing mechanism for keeping the cover plate 11 and the storage box 9 closed. When the storage box 9 is not full, the cover plate 11 is always covered under the action of the covering mechanism, so that the problem that the flax skin enters due to the through air leakage of the storage box 9 is avoided. When the storage box 9 is full, the cover mechanism can open the cover plate 11 to discharge the flax seeds. For example, the closure mechanism may be a spring or a torsion spring. The cover plate 11 is rotatably connected with the frame 1 through a rotating shaft, one end of the spring or the torsion spring is abutted against the frame 1, and the other end of the spring or the torsion spring is abutted against the cover plate 11 so as to cover the cover plate 11.
