Description
Technical field
The present invention designs agricultural machinery technological field, and in particular to a kind of walnut rocks screening machine.
Background technique
It to be generally classified according to its volume after walnut harvest, to be directed to different specification unbundling, or be used
In the different walnut product of production, the maximization of seeking results.Walnut is classified at present, most walnut plantations peasant household is still
By manually being sieved, due to being sieved according to the experience of oneself, not only working efficiency is low, but also is classified effect
Fruit is also unsatisfactory.
China application CN201520847196.8 discloses a kind of novel walnut and rocks screening machine.It includes rack, screening
Case and sieving plate, characterized in that be obliquely installed a screening case in the upper end of rack, several layers sieving plate, sieve are equipped in screening case
The angle of scoreboard and horizontal plane is 3-10 °, and several penetrating screening holes are provided on sieving plate, sieves the diameter in hole from upper sieve
Scoreboard is successively gradually successively decreased to lower layer's sieving plate；The upper right side for sieving case is equipped with a lower hopper, and the top of lower hopper is equipped with motor
The infeed conveyor of driving；Screening case left end correspond at sieving plate be equipped with discharging hang plate, discharge hang plate end just under
Side is equipped with splicing bucket.Walnut is tumbled from the upper right corner of screen plate from the lower left corner under gravity, and when falling to, its diameter is big
When sieving the diameter in hole, it will be dropped into splicing bucket along the screen plate from discharging hang plate.
But this surface of walnut is sufficiently oily, rollability is bad, promotes walnut to roll if increasing the sieving plate gradient, and meeting
It causes walnut rolling speed too fast, causes lesser walnut that cannot be sized removing in time.Therefore separative efficiency is not high.
Summary of the invention
When in order to solve the artificial screening of walnut screening in the prior art and existing mechanical grading, inefficient problem,
The present invention provides a kind of walnuts to rock screening machine.Technical scheme is as follows:

Embodiment 1:
When in order to solve the artificial screening of walnut screening in the prior art and existing mechanical grading, inefficient problem, this hair
Bright one kind walnut as depicted in figs. 1 and 2 that provides rocks screening machine, including pedestal 1 and screening case 2, screening case 2 pass through hollow
Bucking ladder 3 is fixed on pedestal 1.Screening case 2 is fixed on the top surface of hollow bucking ladder 3 by hinge.Screening case sliding is prevented,
It will not allow screening case can not the relatively hollow movement of bucking ladder 3 again.The sieving plate 4 being parallel to each other in screening case 2 equipped with several layers, sieve
The angle of scoreboard 2 and horizontal plane is 3 ~ 8 °.Sieving plate 4 is divided into multiple screening areas, each sieving plate for case 2 is sieved from top to bottom
Several equal-sized screening holes are provided on 4, the diameter for sieving hole successively gradually successively decreases from upper layer sieving plate to lower layer's sieving plate.
When sieving walnut, the biggish screening hole separation in upper layer is biggish walnut, and more downward screening hole is smaller, isolates
The walnut come is also just smaller.
The top surface for sieving case 2 is a slope surface, and higher-end is provided with feed inlet 6, is sieved on the front end face of case 2, each screening
4 low side corresponding position of plate offers corresponding discharge port 7.A guide plate 8 is arranged in the bottom of each discharge port 7, so that walnut is fallen into pair
In the container answered.The walnut occurred in each discharge port with its corresponding to sieving plate screening hole it is in the same size, therefore,
The walnut that each discharge port occurs is not of uniform size, respectively with unused containers.There is channel among guide plate, assist walnut
Into in different containers, prevent walnut unrestrained.
As shown in Figure 1, it further includes swaying mechanism 5 that walnut, which rocks in screening machine, the side of screening case 2 is arranged in swaying mechanism 5
Face, swaying mechanism 5 include that bracket, drive rod 51, sector gear 52, gag lever post 53, rotating disk 54 and motor 55, bracket include
Bottom plate and riser perpendicular to the base plate.One end of gag lever post 53 is fixedly connected with the center of circle of sector gear 52, and link position is cut with scissors
Connect has a waist hole 531 in the middle part of the bottom of riser, gag lever post 53, and rotating disk 54 is fixed on the top of riser, and rotating disk 54
Center be fixedly connected with the output end of motor 55, rotating disk 54 far from a protruding shaft 541 is fixedly installed on the side of motor,
The diameter of the protruding shaft 541 and the width fits of waist hole 531, are inserted into protruding shaft 541 in waist hole 531 just.
Drive rod 51 includes rack gear 511 and round bar 512, and the both ends of rack gear 511 are fixedly connected with round bar 512, drive rod 51
It is mounted on transverse slat by round bar 512, the tooth on rack gear 511 and sector gear 52 is intermeshed, close to the round bar of screening case 2
512, it is connect by spring with screening 2 bottom of case.
When motor 55 drives rotating disk 54 to rotate, protruding shaft 541 is inserted in waist hole, and gag lever post 53 is driven to swing, into
And sector gear 52 or so is driven to fiddle with rack gear 511, so that the reciprocal side-to-side movement of round bar 512 is driven, with the fortune of round bar
It is dynamic, it rolls with the screening case 2 that round bar is connect by spring, walnut is promoted to roll screening.
Embodiment 2:
The present embodiment and the main distinction of embodiment 1 are: in the swaying mechanism course of work, drive rod side-to-side movement more frequency
Numerous, in order to reduce frictional force, the round bar 512 of drive rod is fixed on transverse slat by sleeve, the internal layer of sleeve and 512 gap of round bar
Cooperation, the outer layer of sleeve are fixedly connected with transverse slat, have ball between the internal layer and outer layer of sleeve, reduce round bar table using ball
The frictional force in face.
Embodiment 3:
The present embodiment and the main distinction of embodiment 1 are: adjustable in order to make to rock rate, vibrating mechanism 3 is including further including adjusting
Fast device；The output shaft of motor 55 is connect by shaft coupling with governor, and the output end of governor and the shaft of rotating disk are fixed
Connection.
Walnut rock screening machine use process is as follows:
Walnut is added in screening case by feed inlet, sieves the inclined-plane that the sieving plate in case is 3-8 ° of inclination angle, motor drives
Band rotates disc spins, and the protruding shaft in rotating disk is inserted in waist hole, so that rotating disk drives gag lever post to swing, and then drives fan
Shape gear or so rack gear that fiddles with to drive the reciprocal side-to-side movement of round bar, with the movement of round bar, passes through spring with round bar
The screening case of connection rolls, and walnut is promoted to roll screening.Biggish walnut cannot be by upper during slide downward
The sieving plate of layer, just directly the discharge port corresponding to the sieving plate of upper layer rolls out screening case, falls into corresponding container；It is lesser
Walnut is fallen in lower screen scoreboard from the screening hole on upper layer during scrolling down through, until suitably being sieved by aperture
Hole retention；By such process, walnut not of uniform size is through that quickly can be respectively put into difference according to the size in screening hole
Container in, very efficiently.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
