Description

A kind of nut automatic sieving and hulling machine

Technical field

The present invention relates to a kind of nut cracking equipment, especially a kind of nut automatic sieving and hulling machine.

Background technology

The dry nut such as hickory nut is the essential part of plant, generally all full of nutrition, containing protein, grease, minerals, dimension Raw element is higher, and growth in humans is developed, is built up health, prevents disease and has the effect of fabulous；But nice difficult stripping is the dry heavily fortified point of puzzlement One big technical barrier of fruit processing industry.It is at present, in all parts of the country that there are many food research, universities and colleges break in research hickory nut in one's power Shell machine, tapping machine, principle is mostly identical, using first progress roller classification processing, then carry out the processing of drum extrusion broken shell Mode, equipment investment is big, low production efficiency, and due to hickory nut size and the difference of shape, and broken shell effect is undesirable, Therefore most enterprises are still using the processing method tapped by hand at present, and labor intensity is big, product high processing costs, production Quality is difficult to control.

Therefore it can make the serial dried nut shells such as hickory nut, fibert, green fruit, macadamia, pine nut there is an urgent need to a kind of Uniformly cracking and kernel completely strips the high-efficiency multi-function mechanical device of benevolence convenient for hand, especially hickory nut surface can be made uniformly to open It splits and the more complete Nutcracker of particle, is processed with solving the dry nut such as the hickory nut difficult dry nut of this puzzlement of shelling of being fond of eating The technical barrier of industry.

The present invention is divided into three steps, the first step when using：Nut is sieved as three kinds of specifications according to size；Nut is poured into Start motor 27 after in one screening box 4, motor 27 drives shaft 23 by second shaft coupling 25 again after the deceleration of retarder 26 And two cams 24 being connected in shaft 23 rotate, third screening box 6 lower surface in 24 motion process of cam always High by-pass is kept to contact with cam 24, therefore third screening box 6 and the mounted thereto second screening box 5, first sieve box 4 It can make periodic wobble around hanging rod 3 with the rotation of cam 24 so that nut is divided into three kinds of different sizes, and large size nut is in In first screening box 4, medium size nut is in the second screening box 5, and small size nut is in third screening box 6；In the first screening Box 4 and second sieves the first observation panel M for being formed between box 5, the formed between the second screening box 5 and third screening box 6 Two observation panel N can observe nut screening progress, be powered off in time to motor 27 after the completion of screening, save electric energy in time.

Second step：It takes out nut and is put into nut box 6；Motor 27 is turned off in nut screening after finishing, after motor 27 stalls, The first screening screening of box 4, second box 5, third screening box 6 are disassembled respectively, then sieving the nut in box 4 by first takes Go out and be put into the first receiving cavity A of nut box 6, the nut that second is sieved in box 5 is removed and placed in the second appearance of nut box 6 Receive cavity B, third is sieved the nut in box 6 is removed and placed in the third receiving cavity C of nut box 6.

Third walks：Nut progress of different size and specifications while uniform broken shell to three kinds；Start stepper motor 16, stepping electricity Machine 16 by first shaft coupling 17 drive planetary roller screw leading screw 18 rotate, leading screw 18 set leading screw external screw thread 18.2 with Roller 28 carries out threaded engagement, and roller 28 carries out threaded engagement with nut 32 again simultaneously；Roller 28 is along before leading screw external screw thread 18.2 Into while, the roller screws tooth 28.2 at 28 both ends of roller is engaged with ring gear thread 29.3, both can guarantee that roller 28 surrounds Rotation while leading screw 18 revolves round the sun, and can guarantee that roller 28 is parallel with 18 axis of leading screw, it prevents in transmission process because torque tilts Roller 28 is caused to de-orbit；The cooperation of positioning runner 32.2 and arc boss 19.4 so that nut 32 is circumferentially fixed, finally makes Obtaining roller 28 drives nut 32 to move in a straight line downwards, and it is crowded that the nut 32 moved downward drives the second broken shell pressure head 8 to move down The nut in the second receiving cavity B is pressed, the first broken shell plate 7 and third broken shell that the drive of the second broken shell plate 8 is fixed together with it Plate 9 moves down the nut squeezed in the first receiving cavity A and third receiving cavity C, completes nut first position broken shell；It is primary to squeeze After change stepper motor 16 steering, at this time the leading screw 18 of planetary roller screw rotate backward, roller 28 drive nut 32 It moves up, and then the second broken shell pressure head 8 being threadedly coupled with nut 32 is driven to move upwards, the first broken shell pressure head 7, third are broken Coverboard 9 also moves upwards therewith, then pushes plate 13 several times back and forth, drives the nut rolling in nut box 12 so that nut The part not being extruded upward, repeats and nut is pressed down against, and completes nut second position broken shell；It twitches back and forth again Plate 13 several times drive the nut rolling in nut box 12 so that the other parts that nut is not extruded upward, repeat progress Nut is pressed down against, other position broken shells of completion nut；Repeat above-mentioned extruding work, until completing the arbitrary of nut Position broken shell.

Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent Pipe is described in detail the present invention with reference to foregoing embodiments, it will be understood by those of ordinary skill in the art that：Its according to Can so modify to the technical solution recorded in foregoing embodiments either to which part or all technical features into Row equivalent replacement；And these modifications or replacement, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution The range of scheme.
