Detailed Description

The technical solutions in the present embodiments will be clearly and completely described below with reference to the accompanying drawings in the present embodiments, which, however, should not be construed as limiting the present invention to specific embodiments, but are for explanation and understanding only:

as shown in fig. 1, 2 and 3, the present embodiment provides a tung oil fruit screening device, which comprises a vibrating screen mechanism and a sorting mechanism.

The shale shaker device includes feeder hopper, sieve 11, the motor 12 of 11 vibrations of drive sieve, it has several bar hole 13 to open on the sieve 11, several bar hole 13 is crisscross arranges, through preliminary peeled tung oil fruit, through the mode of vibration on sieve 11, make some not fallen by clean up's peel by bar hole 13 whereabouts, the peel is mostly flat form or tiny graininess, prolate bar hole 13, guarantee that tung oil seed does not fall when being favorable to the whereabouts of peel, and the bar hole 13 of crisscross arranging can increase the probability of tung oil seed through bar hole 13, promote the sieve yield of tiny peel, the discharge gate of sieve 11 is connected with sorting mechanism's feed inlet.

Sorting mechanism includes support 21, several level and installs the roller set on support 21 side by side, drive roller set pivoted actuating mechanism and clearance mechanism, and the roller set includes two roller shafts 22, and two roller shafts 22 are main roll shaft 22 and driven roller shaft 22 respectively, and driven gear is installed to driven roller shaft 22 one end, and main roll shaft 22 one end is installed and is waited big second gear with driven gear meshing and, and first gear is installed to the other end, actuating mechanism includes the worm with the first gear engagement of several and drive worm pivoted motor 12. The motor 12 drives the worm to rotate, so that the primary roller shaft 22 and the secondary roller shaft 22 rotate in opposite directions synchronously.

The lateral wall of the roll shaft 22 is provided with a thread passage 23, the thread rotating directions of the main roll shaft 22 and the driven roll shaft 22 are opposite, the thread pitch of the thread passage 23 is gradually increased along the conveying direction of the sorting mechanism, the thread pitch of the starting part of the thread passage 23 is equal to the width of the strip-shaped hole 13, the thread pitch of the tail end of the thread passage 23 is larger than the size of the tung oil fruits, and when the motor 12 drives the roller set to rotate, the tung oil seeds are pushed to the tail end of the sorting mechanism from the feed port of the. The pitch is gradually increased, so that small tung oil seeds fall first, larger tung oil seeds fall later, and the tung oil seeds adhered with peels have larger volume and finally fall. The box 41 is collected to the small fruit, box 42 is collected to the big fruit and box 43 is collected in doing over again to the transport direction of sorting mechanism below edge sorting mechanism, the box 41 is collected to the small fruit, box 42 is collected to the big fruit and box 43 is collected in doing over again to doing over again, the tung oil seed whereabouts of equidimension not is to the collection box of difference, realize the size screening of tung oil seed, the tung oil seed that falls into box 43 is collected in doing over again will be carried out peeled procedure again, it is few to ensure the tung oil seed epidermis content of selecting, reduce the influence of peel to tung oil purity.

The cleaning mechanisms are arranged below the plurality of roller shafts 22 and comprise cross rods 31 horizontally arranged on the support 21, bristles 32 in annular contact with the threaded channels 23 are arranged on the top surfaces of the cross rods 31, and the bristles 32 are made of materials with hardness and elasticity, such as PET. When the roller 22 rotates, the brush bristles 32 sequentially contact the annular surface of the threaded passage 23 to clean fine slag adhered to the surface of the threaded passage 23, and the surface of the threaded passage 23 can be continuously cleaned due to the elasticity of the brush bristles 32.

The relative both sides wall of horizontal pole 31 all installs collection sediment board 33, and collection sediment board 33 is used for collecting the thin sediment that brush hair 32 brushed down, collection sediment board 33 level and its width are not more than the running roller radius, when guaranteeing to collect thin sediment, avoid the tung oil seed to fall into. The one end that collection sediment board 33 kept away from horizontal pole 31 rolls up upwards and forms the gathering chamber, install the baffle between collection sediment board 33 and the horizontal pole 31, collection sediment board 33 and baffle enclose into box-like, the collection and the storage of the further thin sediment of being convenient for. The cleaning mechanism can prevent peel or other impurities from sticking to affect the operation of the roller shaft 22, and further reduce the peel mixed in the tung oil seeds.

Slag collecting plate 33 is installed at the lateral wall of cross rod 31 through the bounce-back hinge, and during the beginning, slag collecting plate 33 level, and the contained angle between cross rod 31 is 90, when regularly clearing up slag collecting plate 33, remove each box after, will collect slag collecting plate 33 and push down, slag collecting plate 33 is rotatory around articulated department, clean out fine slag can, after external force disappears, slag collecting plate 33 will reply to initial position.

It is to be understood that the above examples are merely illustrative for clarity of description and are not limiting on the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are intended to be within the scope of the invention.
