DETAILED DESCRIPTION

[0030] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] Figure 1-Figure 5As one embodiment of the utility model, a tea dust removal and screening device comprises: a support base 1; a screening and conveying bin 2, which is installed on the support base 1 and outputs the screened dust to the outside, and comprises a bin body 21 and a conveyor belt 22 installed in the bin body 21 for transmitting to the outside; a screening bin 3, which is installed on the upper end of the bin body 21 for separating tea leaves and dust, and comprises a screening bin 31 and a moving track 32 installed on the side wall of the screening bin 31, the screening bin 31 is provided with a feed port 34 and a vibration motor 35 installed thereon, the moving track 32 clamps a screening plate 33, the screening plate 33 moves synchronously with the screening bin 31, and the screening bin 31 is elastically connected to the support base 1;

[0033] The specific problem addressed by this specific embodiment is that the existing solution of using wind power to remove dust mixed in tea leaves is not ideal. The utility model uses a screening bin 3 installed on a supporting base 1, and uses a vibrating motor installed thereon to vibrate it, so as to enable the dust attached or adhered to the tea leaves to break away and move downward through the sieve plate 33. On the other hand, the screening and conveying bin 2 installed at the lower end of the screening bin 3 can timely transport the dust separated from the sieve plate 33 to the outside, reducing the time the dust stays in the bin body 21, thereby enhancing the effect of separating the tea leaves from the dust.

[0034] In one embodiment, the support base 1 includes a support base 11 and a support lining rod 12, the support base 11 is connected to the bin body 21, the support lining rod 12 is placed at the front and rear ends of the bin body 21 and connected to the screen bin 31 through an elastic support rod. Figure 2 As shown in , the elastic support rod includes two straight rods connected to the side wall of the screen bin 31 and the supporting lining rod 12 respectively, and a spring is arranged between the two straight rods. The screen bin 31 vibrates at the upper end of the bin body 21 under the action of the vibration motor 35;

[0035] The sieve plate 33 is arranged in an inclined shape in the sieve bin 31, and a discharge end 36 is arranged on the side wall of the sieve bin 31 away from the feed inlet 34. The discharge end 36 moves synchronously with the sieve bin 31, and a guide plate 37 is arranged inside the sieve bin 31. The maximum height of the guide plate 37 arranged inside the discharge end 36 is less than the minimum height of the sieve plate 33 installed in the sieve bin 31. The tea leaves gradually approach the discharge end 36 on the sieve plate 33, and are output from the sieve bin 31 along the guide plate 37 through the arrangement of the guide plate 37.

[0036] In one embodiment, the feeding range value formed by the feed port 34 is smaller than the receiving range value of the sieve plate 33 at the lower end of the feed port 34 to enhance the carrying capacity of the sieve plate 33 for the material entering the feed port 34. A plurality of partitions 38 are provided on the side wall of the feed port 34. The cavity of the feed port 34 is partitioned into a plurality of channels for dispersing the tea leaves to be screened by the partitions 38. When the tea leaves to be screened are poured into the feed port 34, the partitions 38 act to disperse the tea leaves to be screened into a plurality of piles, thereby enhancing the dispersion range of the tea leaves to be screened on the sieve plate 33.

[0037] The bin body 21 is open and has a track groove 23 on its interface with the sieve bin 31. Therefore, when the sieve bin 31 is acted upon by the vibration motor 35 to generate vertical and horizontal movements, it can be guided in the horizontal direction through the connection with the track groove 23 to avoid front-to-back misalignment with the bin body 21, which would cause the conveyor belt 22 to have an insufficient dust receiving range and cause dust overflow. The opening length of the track groove 23 is adapted to the horizontal offset length of the sieve bin 31, and in this embodiment, a built-in block 39 adapted to the track groove 23 and built into the track groove 23 is provided at the lower end of the sieve bin 31. The opening depth of the track groove 23 is greater than the extension length of the built-in block 39 in the track groove 23. The top surface of the built-in block 39 in the track groove 23 is spaced apart from the top surface of the track groove 23, thereby forming a basis for the vertical movement of the built-in block 39 in the track groove 23.

[0038] In one of the embodiments, the conveyor belt 22 is placed horizontally in the bin body 21 and a guide plate 24 is provided at its upper end, which slides in the bin body 21 and moves synchronously with the screen bin 31. In this embodiment, the conveyor belt 22 is specifically a conveyor belt, which is a commonly used machine in the prior art. The function it realizes in this embodiment is only to transport the dust that falls thereon to the outside of the bin body 21. Therefore, in specific production, increasing or decreasing the length of the conveyor belt 22 based on the limitation of the length of the bin body 21 does not affect its role in this solution.

[0039] In one of the embodiments, there is a distance between the bottom of the guide plate 24 and the conveyor belt 22. The guide plate 24 in this embodiment plays the role of transferring the dust filtered out of the material from the sieve plate 33 to the conveyor belt 22 through the guidance of its inclined plate surface. Therefore, the effective path for the dust to be generated in this embodiment is from the feed port 34 to the sieve plate 33, after sieving, it falls directly from the sieve plate 33 to the conveyor belt 22 or falls onto the conveyor belt 22 through the guide plate 24, and is output outward through the conveyor belt 22. In this way, the layered output of tea leaves and dust is completed.

[0040] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0041] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
