Description

Tea screening device Technical Field The utility model belongs to a tea screening device, and particularly relates to a tea screening device. Background In the processing process of the tea, the tea is also distinguished according to the size of the tea, and the tea is often subjected to screening by using a screen when the tea is screened by the tea which is often provided with impurities after being dried; But the sieve can only one deck sieve to the speed that the sieve sieved the tealeaves has been influenced through the manpower is sieved to the sieve, can not satisfy the screening demand of a large amount of tealeaves, is in traditional screening plant and utilizes tealeaves to pass through gravity's effect on the screen cloth and make tealeaves roll by oneself and sieve, but tealeaves can not sieve completely on the screen cloth, leads to having remaining tealeaves to need sieving through the manual work on the screen cloth. Disclosure of utility model The utility model provides a tea screening device, and aims to solve the problems of the tea screening device in the background technology. The utility model is realized in such a way, the tea screening device comprises a mounting frame, wherein the mounting frame is U-shaped, a plurality of mounting holes are formed in the surface of the mounting frame, a screening cylinder is rotatably arranged on one side of the mounting frame, a feeding pipe is formed in the top of the screening cylinder, a discharging pipe is arranged at the bottom of the screening cylinder, and a screening mechanism is arranged in the screening cylinder; the screening mechanism comprises a plurality of discharging pipes; The screening device comprises a screening barrel, a feeding hole is formed in the side wall of the screening barrel, the feeding hole is formed in the side wall of the feeding pipe, the end portion of the feeding pipe penetrates through the screening barrel and is fixedly connected with the screening barrel, two connecting rods are fixedly connected between the feeding pipe and the inner wall of the screening barrel, a screening net is connected to the outer periphery of the screening barrel in a circulating mode and is arranged in a funnel shape, the periphery of the screening net is rotationally connected with the inner wall of the screening barrel, a driven toothed ring is fixedly connected to the top of the screening net, a driving gear is connected to the top of the driven toothed ring in a meshed mode, a stepping motor is arranged on one side of the driving gear, the side wall of the stepping motor is fixedly connected with the outer wall of the screening barrel, and the output end of the stepping motor is fixedly connected with the driving gear; the surface pore diameters of the screening nets are sequentially reduced from top to bottom; An angle adjusting mechanism is arranged on one side of the screening cylinder and used for adjusting the angle of the screening cylinder; In the initial state, the screening cylinder is obliquely arranged, a feed inlet formed in the surface of the discharge pipe is positioned at the upper part of the screening net rotationally connected with the discharge pipe, then the driving gear can be driven to rotate by starting the stepping motor, meanwhile, the driving gear can drive the funnel-shaped screening net to rotate by driving the driven toothed ring, and a plurality of stepping motors can be started simultaneously to drive a plurality of funnel-shaped screening nets to rotate in the mode, so that the aperture of the funnel-shaped screening nets is sequentially reduced from top to bottom; Then can add tealeaves to the screen cloth surface at top through the inlet pipe, and the tealeaves can slide at the screen cloth surface of slope because of gravity when rotatory at the top screen cloth, thereby accelerate the speed that tealeaves passed through the screen cloth, the tealeaves that can fall into to the screen cloth surface of bottom through the top screen cloth continues screening, until too finely divided tealeaves passes through the screen cloth at bottom and discharges through the row material pipe of screening barrel bottom, a plurality of screen cloth surface remaining tealeaves all are greater than the sieve mesh on a plurality of screen cloth surfaces this moment, thereby accomplish the multistage screening to tealeaves, afterwards adjust screening barrel into vertical state through starting angle adjustment mechanism, the tealeaves that remains at each screen cloth surface can slide to the center of funnel-shaped screen cloth this moment, and along with the rotation of screen cloth drive tealeaves and get into this discharging pipe through the feed inlet that screen cloth center discharging pipe surface was offered, and discharge through this discharging pipe, thereby accomplish the ejection of compact operation to the tealeaves of a plurality of screen cloth surfaces. Preferably, the angle adjusting mechanism
