DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Tea grading and screening is to determine the quality and grade of tea to meet the needs of different consumers. Tea grading helps consumers understand the quality of tea and choose tea that suits their taste and needs. At the same time, tea grading can ensure that tea of ​​the same grade remains consistent in quality and improve the overall quality of tea. In order to achieve convenient replacement of the screen according to the requirements of screening of different tea sizes, and to evenly put tea into the screening device, the subsequent screening efficiency is improved. Please refer to an implementation method disclosed in the following embodiment.

[0022] like Figure 1-Figure 4 As shown, an embodiment provided by the utility model:

[0023] A grading and screening device for tea processing, wherein a feed component 2 is mounted on a vibrating carrier 1 for evenly placing tea leaves, at least two groups of screening components 3 are mounted inside the vibrating carrier 1 for cooperating with the vibrating carrier 1 itself to realize the vibrating screening function of tea leaves, a discharge hopper 4 for discharging tea leaves from the screening component 3 is plugged into one side of the vibrating carrier 1, a baffle plugged into the discharge hopper 4 is used to block the outlet to prevent tea leaves from being discharged from the discharge hopper 4 during the vibrating screening stage, and an extension plate mounted on the baffle is used to improve the convenience of lifting. In actual applications, tea leaves are placed into the feed component 2, and then evenly spread on the upper surface of the screening component 3, and in combination with the vibration effect provided by the vibrating carrier 1 itself, the tea leaves are shaken at a certain frequency on the upper surface of the screening component 3, so that tea leaves particles can be separated on the screening component 3, and by equipping at least two groups of screening components 3 with inconsistent hole gaps, grading and screening by vibration can be realized;

[0024] like Figure 1 and Figure 2As shown, the screening component 3 includes a three-side enclosure 301 fixedly installed inside the vibration carrier 1, and magnetic support strips 302 are installed on both sides of the bottom of the three-side enclosure 301. A screen structure 303 extending into the interior of the three-side enclosure 301 and mutually attracted with the magnetic support strips 302 is inserted on the front of the vibration carrier 1, and the rear ends of the bottoms of the two magnetic support strips 302 are fixedly installed with a bearing support plate 304, and the screen structure 303 and the magnetic support strip 302 are both provided with a through slot 305. A spring for locking the screen structure 303 and the magnetic support strip 302 through the through slot 305 is installed on the bearing support plate 304. The spring rod 3041 is squeezed downward along the through slot 305, so that the spring rod 3041 shrinks in length downward, and the top of the spring rod 3041 gradually separates from the screen structure 303 downward, thereby achieving the purpose of unlocking the screen structure 303 and the magnetic support bar 302. Thereafter, the screen structure 303 can be pulled forward with great force to be extracted from the inside of the vibration carrier 1, so as to facilitate the replacement of the screen structure 303. In addition, magnetic suction plates adapted to the magnetic support bar 302 are installed on both sides of the bottom of the screen structure 303, which effectively increase the firmness of the screen structure 303 and the magnetic support bar 302 when they are combined.

[0025] In traditional tea screening equipment, after the tea leaves are put into the hopper, the tea leaves discharged downward from the hopper will be concentrated on one spot on the surface of the screen, thus affecting the efficiency of subsequent tea screening. In order to solve this problem, Figure 1 and Figure 3 As shown, the feeding assembly 2 includes a feeding hopper 201 arranged above the vibrating carrier 1, and feeding frames 202 for transferring tea leaves are installed on both sides of the feeding hopper 201, and the inclination of the feeding frame 202 is not less than 20°. Combing rods 203 for dispersing and discharging tea leaves are clamped on the feeding frame 202, and a load-bearing frame 204 is installed on the feeding hopper 201. An electric guide rail 205 slidably connected with the load-bearing frame 204 and used to drive the feeding frame 202 to move horizontally at a uniform speed is installed on the vibrating carrier 1. The feeding hopper 201 is wide at the top and narrow at the bottom, which can reduce the speed of discharging tea leaves from the feed hopper 201. In actual use, the tea leaves are put into the feed hopper 201, and then fall down into the discharge frame 202, and are gradually discharged outward along the inclined discharge frame 202. At the same time, the comb rod 203 is used to disperse the tea leaves to prevent them from sliding down along the middle of the discharge frame 202 in an accumulated manner. In addition, the electric guide rail 205 is used to drive the feed hopper 201 and the discharge frame 202 to move at a uniform speed along the vibration carrier 1 at a set speed, so that the discharged tea leaves are spread more evenly on the surface of the upper screen structure 303, thereby improving the efficiency and effect of subsequent screening.

[0026] like Figure 4As shown, the vibration carrier 1 includes a frame structure 101 as a device carrier, an elastic structure 102 is installed at the bottom of the frame structure 101, and a vibration motor 103 is installed on the back of the frame structure 101 to cooperate with the elastic structure 102 to shake and screen tea leaves. The vibration motor 103 is used to cooperate with the elastic structure 102 to generate vibration of a set frequency, so that the tea particles shake on the upper surface of the screen structure 303, thereby promoting the separation of tea particles according to size.
