Description

Processing equipment for tea leaves

Technical Field

The utility model relates to an agricultural product processing equipment technical field, concretely relates to processing equipment for tealeaves.

Background

The tea leaf circular sieve machine is one of the main devices in tea leaf processing, and is used for sieving and grading tea leaves according to the differences of tea leaf shapes, lengths, thicknesses, particle sizes and the like, and a motor drives a sieve to move through a transmission mechanism, so that the tea leaves are sieved and graded in the moving process. In the actual operation in-process, need the continuous screen cloth of rocking from top to bottom, the displacement of rocking from top to bottom is big, and the screening is more thorough, and tealeaves can produce a large amount of broken tea and tea dust rocking the in-process, and these tea dust can be along with air current and overflow and drift in the air and fall to amass on mechanical equipment, cause the injury and influence mechanical equipment's life to operating personnel's healthy.

For this reason, a tea leaf screening device disclosed in CN203356057U is characterized in that a dust collector is communicated with the right side of a screening bed, and the dust collector is used for generating suction force to collect dust, but during the screening process, tea leaves freely fall down and can deviate in the direction under the action of the suction force of the dust collector, the deviation distance is large, the tea leaves fall to a discharge port on the right side of the screening bed and fall out from the discharge port, the tea leaf screening time is short, and the tea leaf screening efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a processing equipment for tealeaves to solve among the prior art problem that tealeaves takes place great skew under the effect of dust catcher.

In order to solve the above problem, the utility model provides a following technical scheme: the utility model provides a processing equipment for tealeaves, includes the screening case, the right side of screening case is equipped with the discharge gate, be equipped with the screen cloth towards the discharge gate downward sloping in the screening case, the screen cloth is connected with the screening motor, the right side intercommunication of screening case has the dust absorption pipe, the dust absorption union coupling has the air exhauster, the intraductal rotation of dust absorption is connected with the pivot, the pivot is connected with the gasket that is used for sealed dust absorption pipe, the pivot is still coaxial fixed cup jointed and is located the outside bevel gear of dust absorption pipe, the lateral wall of screening case still rotates and is connected with the helical gear with bevel gear meshing, the helical gear meshing has the rack, rack and screen cloth.

The utility model discloses a theory of operation: the screening motor drives the screen to move up and down in the screening box, when the screen moves up, the screen drives the rack to move up, the rack drives the bevel gear to rotate through the bevel gear, the bevel gear drives the sealing sheet to gradually rotate through the rotating shaft, and when the screen moves up to the highest point, the sealing sheet completely seals the dust absorption pipe; the screen cloth moves downwards gradually, the sealing sheet rotates gradually, the suction force generated to the falling tea leaves is small, the offset distance of the tea leaves under the action of the suction force is short, and the time for screening the tea leaves on the screen cloth is longer.

The utility model has the advantages that: when tealeaves free fall, the gasket takes place to rotate at the dust absorption pipe gradually, and the suction that the dust absorption pipe produced increases from zero gradually from the suction that the dust absorption pipe produced, and the suction that the dust absorption pipe produced is less, and the distance that tealeaves takes place the skew under the effect of suction is shorter, and the time that tealeaves was screened on the screen cloth is longer.

Furthermore, a filter screen is arranged at the pipe orifice of the dust collection pipe. The purpose of this setting is to prevent that the tealeaves piece from inhaling in the suction fan through the dust absorption pipe, causing the blade of suction fan impaired.

Further, the exhaust fan is communicated with a dust outlet pipe, and the dust outlet pipe is communicated with a water tank. The tea dust is blown to the water tank through the dust outlet pipe, then is wetted by the water in the water tank and falls into the water.

Further, a plurality of water spraying heads are arranged on the top inner wall of the water tank. The water spray head is utilized to spray water mist to the tea dust, and the water mist can submerge the tea dust.

Further, the discharge hole is communicated with a spiral discharge groove. The spiral discharge chute can slow down the impulsive force of tealeaves gliding downwards, can slow down simultaneously that the tea dirt runs out through the discharge chute.

Further, the bottom of screening case is equipped with the universal wheel. Utilize the universal wheel to conveniently remove the screening case.
