Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically to a tea impurity removal mechanism. Background Technology

[0002] After picking, tea leaves need to undergo preliminary screening to remove impurities mixed in during picking, thus preventing them from affecting the taste of the tea. In this regard, patent document CN222491016U proposes a dust removal device, which adds a dust removal mechanism for knocking and vibration at the bottom of the box and installs a blowing component below the feed inlet. The blowing component performs preliminary air separation on the falling tea leaves, and then the dust removal component knocks them for secondary separation. The drawback is that when the tea leaves fall in in clumps, the air separation effect is poor and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a tea impurity removal mechanism, including an inclined box and an inlet on one side of the top surface of the box. An inlet cylinder is provided at the inlet and the two are connected. The inlet of the inlet cylinder is inclined to one side and the inlet cylinder is rotatably connected to the box wall at the inlet. The diameter of the top inlet of the inlet cylinder is larger than the diameter of the bottom outlet. Baffles are alternately arranged in the cavity of the inlet cylinder and the length of the baffle is smaller than the diameter of the cavity segment. The baffles are inclined and the end of the first baffle is elastically hinged to the cavity wall.

[0005] In this design, the feed cylinder is rotatably connected to the feed inlet column wall, allowing the inlet orientation to be adjusted as needed for ease of use. Furthermore, baffles are alternately installed inside the feed cylinder cavity to appropriately block the falling tea leaves, preventing them from clumping together and facilitating subsequent air blowing and screening, thereby improving stability and the quality of the tea leaves being screened.

[0006] Furthermore, a connecting cylinder is provided at the feed inlet, which is fitted and connected to the lower part of the feed cylinder. A retaining ring is provided on the lower peripheral wall of the feed cylinder. A hoop is provided on the connecting cylinder, and protrusions are provided on the two legs of the hoop. The protrusions extend into the cavity of the retaining ring through holes formed on the peripheral wall of the connecting cylinder to axially limit the feed cylinder. This increases the convenience of docking the connecting cylinder with the feed cylinder. The cooperation between the hoop and the retaining ring helps to axially limit the feed cylinder and improve stability.

[0007] Furthermore, the hoop is semi-circular, and a groove for inserting the hoop is provided on the peripheral wall of the connecting cylinder to improve the stability of the hoop.

[0008] Furthermore, a hinge seat is provided inside the inlet cavity of the feed cylinder, and a receiving groove is provided on one side of the hinge seat. The end of the first baffle is located in the receiving groove and is hinged to its groove wall. An elastic element is provided between the bottom surface of the baffle and the corresponding groove wall. The hinge configuration at the receiving groove helps to avoid the influence of tea leaves. The elastic hinge of the baffle can adjust the tilt angle according to the weight of the tea leaves poured in, which helps to reduce clogging.

[0009] Furthermore, an elastic layer is provided on the lower peripheral wall of the feed cylinder. Adding an elastic layer helps to improve the stability of the connection between the feed cylinder and the connecting cylinder, and also helps to reduce noise.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model rotatably connects the feed cylinder to the housing of the impurity removal mechanism to facilitate adjustment of the inlet orientation, and adds a baffle to appropriately limit the input tea leaves, which helps the tea leaves fall in batches, thereby facilitating subsequent blowing and screening work and improving the stability of operation.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 , Figure 2As shown, the tea impurity removal mechanism in this example includes an inclined housing 1, allowing tea leaves to slide down under gravity. The housing has a double-chamber configuration as shown in CN222491016U, where a vibration-type impurity removal mechanism taps the tea leaves to separate them from impurities. An inlet is formed on one side of the top surface of housing 1, and a blowing assembly is installed on the same side as shown in CN222491016U. Tea leaves entering through the inlet are first initially separated by airflow from the blowing assembly, and then further separated by vibration.

[0021] In this example, a feed cylinder 2 is installed at the inlet and connected to it. The feed cylinder 2 has a vertical lower section and an upper section that slopes to one side. This sloped inlet facilitates the pouring of tea leaves. The diameter of the upper opening (inlet) of the feed cylinder 2 is larger than the diameter of the bottom outlet, creating a funnel-like shape for easy tea pouring. The feed cylinder 2 is rotatably connected to the box wall at the inlet. Specifically, a connecting cylinder 3 is fixed to the box wall at the inlet using bolts. The lower part of the feed cylinder 2 is axially inserted into the connecting cylinder 3, forming a nested connection that allows relative rotation. To improve stability, an elastic layer, such as rubber, can be applied to the lower circumferential wall of the feed cylinder 2. This elastic layer, abutting against the connecting cylinder wall, helps improve the stability of the feed cylinder.

[0022] To axially restrict the disengagement of the connecting cylinder, in this example, a circumferential groove is formed on the lower peripheral wall of the feed cylinder 2, i.e., the retaining ring 10, and a mounting groove is formed on the peripheral wall of the connecting cylinder 3, such as... Figure 3 As shown, a semi-annular clamp 8 is fitted onto the connecting cylinder 3 and positioned in the mounting groove. Two protrusions 9 are formed opposite each other at the two legs of the clamp 8. The protrusions 9 extend from holes formed in the peripheral wall of the connecting cylinder 3 into the cavity of the retaining ring to axially limit the feeding cylinder 2. The clamp is molded from materials such as plastic. Furthermore, a rod or plate, i.e., a force-bearing part 11, can be formed protruding outwards at the outer side of the clamp corresponding to the protrusion 9, allowing for finger application to pull the protrusion outwards.

[0023] In this example, baffles 4 are alternately placed inside the cavity of the feed cylinder 2, and the length of the baffle 4 is smaller than the diameter of the cavity segment it is in. Figure 1 , Figure 2 As shown, the baffle 4 is inclined and the end of the baffle 4 is spaced at a predetermined distance from the opposite cavity wall to allow the tea leaves to fall. When in use, if the tea leaves enter from the feed cylinder inlet, they will be limited by the baffles in sequence, and the clumps of tea leaves will fall in batches, which will facilitate the subsequent blowing of the blowing component for initial separation.

[0024] In this example, the end of the first baffle 4 is elastically hinged to the cavity wall. For example, the inlet cavity of the feed cylinder 2 has a convex hinge seat 6 inside and outside, and a recessed receiving groove 7 is formed on one side of the hinge seat 6. The end of the first baffle 4 is located in the receiving groove 7 and is hinged to its groove wall to rotate up and down. An elastic element 5 is installed between the bottom surface of the baffle 4 and the corresponding groove wall below. If a spring is used as the elastic element, when too much tea leaves enter, the first baffle can rotate down to expand the channel for the tea leaves to fall, which helps to reduce blockage.

[0025] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
