Description
Technical field
The invention belongs to tea-processing equipment technical fields, specifically disclose a kind of tea screening device.
Background technology
After just system, quality characteristic has basically formed tealeaves.But due to primary processing of tea comparision of production disperse, picking it is tender
Degree differs, and just technology processed is different, thus, the quality specification of gross tea is complicated.In order to improve the commodity value of tealeaves, make production
Product quality specification, it is necessary to which the needs that domestic market is just adapted to by fine manufacture are finally met the requirements of consumers.
The technological process of tea leaf refining is different and different because tea kinds, teas of the same race, and the technological process of each tea processing factory is not yet
It is identical to the greatest extent.But its purpose is substantially the same, mainly：Ornamenting shape divides and does pattern, detaches old tender, divided rank, and rejecting time is miscellaneous,
Pure product, humidity drying, adjustment quality, stabilised quality.But no matter which kind of technological process is used, be required to by screening, carefully
Wind cutting choosing is picked and is picked and re-dry.It usually will appear problems with during tea screening：(1) prior art uses
The mode of continuous feed carries out screening tealeaves, and inlet amount causes greatly the size distribution of tea screening uneven so that point of tealeaves
It is bad from effect；(2) when sieving tealeaves, discharge velocity is big, is easy to make unsegregated tealeaves to mix discharging, does not play point
From effect.
Invention content
The purpose of the present invention is to provide a kind of tea screening devices, to solve to lead to tea screening greatly due to inlet amount
Size distribution is uneven, the problem for causing the separating effect of tealeaves bad.
In order to achieve the above object, base case of the invention is：Tea screening device, including pedestal, on the pedestal
Equipped with holder, the holder is equipped with the sieve bucket being slidably connected with it, and the lower face of the sieve bucket is inclined-plane, the middle of the base
Equipped with the motor that output shaft is arranged upwards, the output shaft of the motor is equipped with turntable, on position of the turntable far from axle center
Equipped with mandril, the mandril is slidably connected with inclined-plane；The top of the sieve bucket is equipped with feed inlet, and the frame upper is equipped with blowing
Bucket, the drain hopper are slidably connected with sieve bucket, and the drain hopper is equipped with can be with the drain hole of feed inlet face；In the sieve bucket
It is equipped with multiple sieve plate successively from top to bottom, the screen-aperture of multiple sieve plates is sequentially increased from top to bottom, and the sieve bucket position is in each
Position above sieve plate is equipped with discharge port, and the top of the motor output shaft is equipped with the supporting rod being rotatablely connected with it, described
Supporting rod is equipped with piston head, and the piston head is slidingly and sealingly connect with sieve bucket inner wall, and the sieve bucket position is above piston head
Position be equipped with the first check valve of the one-way conduction into sieve bucket, the discharge outlet is equipped with the of the one-way conduction to outside sieve bucket
Two check valves.
The operation principle of this base case is：Before the present apparatus, first the tealeaves sieved will be needed to be placed into drain hopper
In, start motor, motor rotation drives turntable rotation, turntable rotation to drive mandril rotation；It is oblique due to mandril and sieve bucket lower end
Face is slidably connected, and sieve bucket is connect with bracket slide, and therefore, when mandril is rotated with the output shaft of motor, the upper end edge of mandril is oblique
It slides in face；When mandril is located at the highest point on inclined-plane, drain hole on drain hopper and feed inlet face, the tealeaves in drain hopper are fallen into
Into sieve bucket；From the eminence on inclined-plane into inclined-plane lower sliding process, sieve bucket moves down mandril；Mandril slides energy on inclined-plane
Sieve bucket is driven to move up and down, sieve bucket, which moves up and down, drives sieve plate to move up and down, and sieve plate, which moves up and down, to play the tealeaves in sieve bucket
It is acted on to shake；Due to being equipped with multiple sieve plates from top to bottom in sieve bucket, the screen-aperture of multiple sieve plates is sequentially increased from top to bottom,
Therefore the tealeaves sieved in bucket can be sieved when sieve plate is moved up and down with sieve bucket.Due to the output shaft of motor be equipped with and its
The supporting rod of rotation connection, supporting rod are equipped with the piston head slidingly and sealingly being connect with sieve bucket inner wall, and mandril is by the low of inclined-plane
Place hoists in moving process, and piston head is moved down relative to sieve bucket, and the second check valve is closed, the first check valve
In the open state, air is entered by the first check valve in sieve bucket；When mandril is moved to the lower process by the eminence on inclined-plane
In, piston head is moved up along sieve bucket inner wall, and piston head moves up the air above extrusion piston head, in the process, the
One closed check valve, the second check valve is opened, and under airflow function, air-flow drives tealeaves discharge sieve bucket.
The advantageous effect of this base case is：
(1) by the way that the drain hopper being slidably connected with sieve bucket is arranged on holder, blowing can be realized when sieving bucket and moving up and down
The intermittence of mouth and feed inlet is fed, and intermittence charging can control inlet amount, and tealeaves in sieve bucket can be prevented by control inlet amount
Excessively it is unfavorable for sieving to measuring；
(2) drive mandril rotation that can realize moving up and down for sieve bucket by motor, sieve bucket moves up and down can be in sieve bucket
Tealeaves is shaken, and sieve bucket shake can make tea screening uniform；
(3) by being equipped with the supporting rod of rotation connection on the output shaft of motor, setting and sieve bucket inner wall on supporting rod
The piston head slidingly and sealingly connected, convenient for sieve bucket move up and down when make piston head relative to sieve bucket generate movement, sieve bucket to
Into sieve bucket, air-breathing, sieve bucket are vented when moving down, can realize self-emptying by being vented outward, reduce outward when upper mobile
The operation artificially to discharge；
(4) in discharging, feed inlet is closed the present apparatus, is conducive in time isolate the tealeaves of screening in this way
Bucket is sieved, avoids mixing with unsized tealeaves.
Compared with prior art, present apparatus screening effect is good, and screening efficiency is high.
Further, position of the sieve bucket position above discharge port is equipped with inclined stock guide, and the stock guide is located at
The side of material mouth is higher than the other side.When sieve bucket moves down, piston head pushes air to move up, and is led when air moves up
Flitch can generate air barrier effect, and air moves after being stopped to adjacent discharge port, and being convenient for by air movement will
Tealeaves takes sieve bucket out of；During air moves up, air can play the role of stirring to the tealeaves being packed together, and be convenient for sieve plate will
Smaller tealeaves sieves downwards.
Further, middle part of the discharge port between two neighboring sieve plate.Setting is convenient for having heap on sieve plate in this way
Long-pending tealeaves can will be deposited in the tealeaves discharge sieve bucket of top layer when discharging so that screening effect is more preferable.
Further, the sieve plate is located at the side of discharge port less than the other side.Sieve plate is obliquely installed convenient for tealeaves to going out
Material mouth side is accumulated, and is convenient for quickly discharging when the second check valve is opened.
Further, the discharge outlet is equipped with passage.By passage convenient for collecting the tealeaves outside discharge sieve bucket, it is conducive to
Subsequent packages.
