Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a screening device for tea processing. Background Technology

[0002] Tea leaves, usually referring to the leaves and buds of the tea plant, can be processed into beverages. During the processing of tea leaves, impurities need to be sieved out.

[0003] Chinese Patent 202323302853.4 discloses a high-efficiency tea processing screening device, including a main body comprising a screening box and a screening plate. The screening box has first grooves on both sides, with telescopic supports installed inside each groove. Springs are connected to the telescopic supports. A striking mechanism is installed inside the screening box, comprising a motor housing, a chain, and a rotating rod. The motor drives a first sprocket to rotate, which, in conjunction with the chain and a second sprocket, drives the rotating rod to rotate, which in turn drives a cam to rotate. The rotation of the cam intermittently strikes the screening plate. Combined with the telescopic supports and springs, this allows the screening plate to reciprocate left and right, facilitating the screening of tea leaves. An electric telescopic rod moves a hopper, ensuring that the tea leaves in the hopper are evenly distributed on the screening plate, preventing tea leaves from concentrating in one area and affecting screening efficiency.

[0004] However, when operators need to pour all the tea leaves directly into the hopper, the tea leaves may cause blockages, requiring operators to clear the blockages, which is quite troublesome. When operators gradually pour the tea leaves into the moving hopper, they need to control the rhythm of tea leaf introduction according to the real-time movement trajectory of the hopper, which increases the difficulty of manual operation and may also cause tea leaves to spill or be wasted, affecting the overall work efficiency and operating experience. Therefore, a screening device for tea processing is proposed to solve the above problems. Utility Model Content

[0027] like Figure 1-5 As shown, the present invention proposes a screening device for tea processing, including a screening shell 18 and a vibrating screening plate 8. The vibrating screening plate 8 is located inside the screening shell 18. It also includes an outer frame 9, which is rotatably connected to the inner end face of the screening shell 18. The vibrating screening plate 8 is disposed on the inner end face of the outer frame 9. The outer end face of the screening shell 18 is also provided with a first motor 3. The output shaft of the first motor 3 passes through the outer end face of the screening shell 18 and is connected to one end of the outer frame 9.

[0028] The lower sides of both sides of the outer end face of the screening shell 18 are connected to the base plate 13 through support components. The upper end face of the base plate 13 is also provided with a feeding component, and the bottom of the screening shell 18 is provided with a second feeding hopper 17.

[0029] Movable components are provided on the upper sides of both sides of the outer end face of the screening shell 18. The moving ends of the two movable components are connected to the first feeding hopper 2 through the connecting frame 4. The top of the first feeding hopper 2 is detachably connected to the mounting cover 1. The top of the mounting cover 1 is provided with a diversion pipe 5. The upper end of the diversion pipe 5 is connected to the upper discharge end of the feeding component through the connecting pipe 6. The connecting pipe 6 is a flexible pipe and the length of the connecting pipe 6 is suitable. The mounting cover 1 can be removed from the first feeding hopper 2, so as to facilitate the cleaning of the inside of the first feeding hopper 2.

[0030] In this invention, during use, the vibrating screen plate 8 is first activated to make it vibrate. Then, the moving components on both sides are activated. The moving components on both sides can drive the first hopper 2 to move along the screen via the connecting frame 4. At this time, the feeding component is activated and tea leaves are added to the feed end of the feeding component. The tea leaves are fed through the feeding component and then guided into the diversion pipe 5 through the connecting pipe 6. The tea leaves inside the diversion pipe 5 can fall onto the vibrating screen plate 8 through the first hopper 2. Because the first hopper 2 is moving, the tea leaves can be evenly distributed on the screen plate. The vibrating screen plate 8 prevents tea leaves from concentrating in one place, thus affecting screening efficiency. The screened impurities will fall down and eventually drop into the pre-prepared impurity collection box through the second hopper 17. When it is necessary to remove the tea leaves from the vibrating screen plate 8, the first hopper 2 is moved to the rightmost end by the moving component, and then the first motor 3 is started. The first motor 3 can drive the outer frame 9 to rotate. When the outer frame 9 rotates, it also drives the vibrating screen plate 8 to rotate. The tea leaves will fall into the pre-prepared tea collection box through the second hopper 17, thus facilitating collection.

[0031] In an optional embodiment, the feeding assembly includes a feeding cylinder 16, a second motor 7, a discharge pipe 19, a feeding shaft 20, and a feeding component. The feeding cylinder 16 is located on the upper end face of the base plate 13, the second motor 7 is located on the upper end face of the feeding cylinder 16, the feeding shaft 20 is rotatably connected between the upper and lower inner walls of the feeding cylinder 16, the output shaft of the second motor 7 passes through the upper end face of the feeding cylinder 16 and is coaxially connected to the upper end of the feeding shaft 20 through a coupling, the feeding component is located below the outer end face of the feeding cylinder 16, the discharge pipe 19 is located above the outer end face of the feeding cylinder 16, and the discharge end of the discharge pipe 19 is connected to the connecting pipe 6. The feeding component includes a feeding hopper 14 and a feeding pipe 15. The lower part of the outer end face of the feeding cylinder 16 is connected to the feeding hopper 14 through the feeding pipe 15, and the feeding end of the feeding hopper 14 faces upward.

[0032] It should be noted that when adding tea leaves, the second motor 7 is started. The second motor 7 can drive the feeding auger 20 to rotate. Then, by adding tea leaves into the feed hopper 14, these tea leaves will enter the feed cylinder 16 through the feeding pipe 15. Since the feeding auger 20 is rotating, these tea leaves will move upward and finally fall out through the discharge pipe 19.

[0033] In an optional embodiment, the moving component includes a mounting housing 10, a slide bar 21, a moving block 24, and a moving part. The upper sides of both sides of the outer end face of the screening housing 18 are respectively connected to the mounting housing 10. The slide bar 21 is disposed between the inner walls of the mounting housing 10. The moving block 24 is slidably sleeved on the outer end face of the slide bar 21. The upper end of the moving block 24 is connected to the outer end face of the first discharge hopper 2 through the connecting frame 4. The moving part is disposed on the inner bottom wall of the mounting housing 10. The moving part includes a slide rail 22 and an electric slider 23. The slide rail 22 is disposed on the inner bottom wall of the mounting housing 10. One end of the electric slider 23 is slidably connected to the slide rail 22, and the other end of the electric slider 23 is connected to the moving block 24.

[0034] It should be noted that when the electric sliders 23 on both sides are activated, the electric sliders 23 can drive the moving block 24 to move. When the moving block 24 moves, it can drive the first hopper 2 to move along with it through the connecting frame 4. Moreover, when the moving block 24 moves, it can slide on the outer end face of the slide rod 21, which ensures the stability of the movement of the moving block 24.

[0035] In an optional embodiment, the support assembly includes a side plate 11 and support columns 12. The lower sides of both sides of the outer end face of the screening housing 18 are respectively connected to the side plate 11, and the bottom of the side plate 11 is connected to the bottom plate 13 through multiple support columns 12.

[0036] It should be noted that multiple support columns 12 can support the side plates 11, and the side plates 11 on both sides can support the screening shell 18.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
