Description

Empty and shrivelled walnut sorting machine

Technical Field

The utility model relates to an agricultural product processing equipment especially relates to a machine is selected to empty flat walnut.

Background

The walnut is a dry fruit rich in nutrition, the walnut has hard shells and nuts, in the growth process of the walnut, partial walnut fruits are not full, some walnut fruits are even empty, if empty walnut fruits are not removed, the quality of the whole batch of walnuts can be influenced, the commercial value is influenced, the empty walnut fruits need to be selected out for independent treatment in the production process of the walnut, the uniformity of the whole batch of walnuts is improved, if the empty walnut fruits are selected by observing the appearance and feeling manually, the success rate is low, the production efficiency is low, no practical empty walnut selecting equipment exists at present, and the requirement of actual production cannot be met.

Disclosure of Invention

The utility model aims at providing a machine is selected to empty flat walnut, it can solve the not enough of above-mentioned existence, empty flat walnut is because inside has great space and fruit not full, the empty flat walnut of the same overall dimension and the weight difference of qualified walnut are obvious, the difference of the density of utilizing empty flat walnut and qualified walnut, in airtight space, adopt wind-force to suck away empty flat walnut, use separator to separate out, outside exporting the eduction gear alone, qualified walnut falls the eduction gear outside naturally, respectively to empty flat walnut and qualified walnut collect the packing, and has high production efficiency, empty flat walnut selects the error little, low in production cost's advantage, be fit for the mass production of walnut.

The utility model aims at realizing according to the following technical scheme: the empty and shrivelled walnut selecting machine consists of a feed hopper, a vibration conveying mechanism, an eccentric vibration motor, a rack, an air inlet hole, a selecting chamber, a fan, a cyclone separator, an empty and shrivelled walnut collecting chamber and a qualified walnut collecting chamber, wherein the feed hopper is arranged on the rack and positioned at the front end of the machine, the feed hopper is made into a square shape or a circular shape, an outlet of the feed hopper is connected to a feed end of the vibration conveying mechanism, the vibration conveying mechanism is arranged on the rack and obliquely and downwards arranged, a contact part with the rack is in spring connection, the vibration conveying mechanism is made into a rectangular groove-shaped structure, the eccentric vibration motor is arranged on the vibration conveying mechanism and used as a power source for conveying, a mechanical connecting rod mechanism can also be adopted to generate vibration and transmit power, the selecting chamber is connected to the tail end of the vibration conveying mechanism, the selecting chamber is fixed on the, the bottom of selecting the room stretches into for vibration conveyor constructs and selects indoor part constitution, it has the fresh air inlet to process on the bottom, a use for the air inlet, it sets up adjustable door to select the room import, the degree of opening of door can only allow the walnut on 1~2 layers to get into selects the room, the walnut is more even in the quantity of selecting the room, the air-supply line of cyclone is connected to the upper end of selecting the room, the lower extreme of selecting the room is connected qualified walnut and is collected the chamber, cyclone's air outlet connection fan, empty walnut is connected to cyclone's bottom and is collected the chamber, empty walnut is collected outside the chamber discharge machine from empty walnut, the amount of wind is adjusted to fan export installation air door, cyclone upper portion is the cylinder, the lower part is the taper shape, the air inlet is followed the tangent direction air inlet of cylinder, the centre of cylinder is the straight tube, a use for the.

The theory of operation, add the feeder hopper with the walnut in, start eccentric vibrating motor and fan, the air damper size, make amount of wind and wind pressure can inhale cyclone with empty flat walnut, the walnut gets into behind the conveying mechanism that vibrates, jump forward's removal under the effect of vibrating force, get into and select the room, under the wind-force effect of upwards taking out of fan, empty flat walnut suspension is in the air, because the density of empty flat walnut is little, upward movement under the wind-force effect of fan, the tangential gets into cyclone, empty flat walnut is rotatory along the inner wall in cyclone, produce centrifugal force, the circular cone part falls into empty flat walnut collection chamber below, the interval certain time discharges once, the qualified walnut that density is big falls into qualified collection chamber, the interval certain time discharges once.

Due to the adoption of the technical scheme, the empty and shriveled walnut selecting machine selects empty and shriveled walnuts by utilizing the wind power, so that the production efficiency is high, the error of the empty and shriveled walnuts is small, the production cost is low, and the empty and shriveled walnut selecting machine is suitable for mass production.
