Description

Technical Field

[0001] The utility model relates to the technical field of tea screening and processing, in particular to a tea screening device for tea planting. Background Art

[0002] Artemisia capillaris Thunb., commonly known as cypress wormwood, is the seedling of the perennial herb Artemisia capillaris Thunb. of the Compositae family. It is distributed in most parts of China and is harvested every spring. The tender and fragrant ones are the best. It is the main medicine for traditional Chinese medicine to treat damp-heat jaundice. Modern medical research shows that Artemisia capillaris Thunb. not only has extremely high medicinal value, but also is rich in vitamin C and vitamin B, contains various trace elements and more than twenty kinds of amino acids needed by the human body, and has good health care functions.

[0003] After tea is picked, since the tea contains tea leaves of different sizes, it is necessary to screen the tea in layers. The existing tea is screened and processed by a screening component for horizontal screening, so that the material reciprocates on the surface of the screening component to complete the screening and processing. However, at the same time, when the material is horizontally screened, some materials are easily stuck with the screen aperture, resulting in blockage of the remaining materials during screening, affecting the filtration efficiency. For this reason, we propose a tea screening device for tea planting. Summary of the Utility Model

[0004] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a tea screening device for tea planting.

[0005] To achieve the above object, the utility model adopts the following technical scheme. A tea screening device for tea planting includes a mounting frame and a bottom support. Two sets of assembled and matched screening inner drums are arranged inside the mounting frame. Two sets of assembled and matched screening outer drums are sleeved outside the screening inner drums. The two sets of screening inner drums and screening outer drums are movably connected and matched through hinges. Sieve holes are formed in the peripheries of the screening inner drums and the screening outer drums. Position-limiting sleeves are arranged at the positions corresponding to the sieve holes on the periphery of the screening inner drums. A top material shaft for top material cooperation is telescopically arranged inside the position-limiting sleeves. The peripheries of the position-limiting sleeves are supported and connected with the periphery of the screening inner drums through a support mechanism. The two ends of the top material shaft are respectively provided with a first limiting member and a second limiting member.

[0006] Preferably, when the screening inner drum drives the tea inside the screening inner drum to rotate, when the top material shaft inside the position-limiting sleeve rotates to the lower position in cooperation with the screening inner drum, the top material shaft is in a telescopic sliding state away from the sieve hole, and the end of the top material shaft is limited and supported with the position-limiting sleeve through the second limiting member.

[0007] Preferably, when the top feed shaft inside the limit sleeve rotates to the upper position in cooperation with the inner screening drum, one end of the top feed shaft enters the sieve holes to top the jammed tea leaves.

[0008] Preferably, when the two groups of inner screening drums drive the tea leaves inside the inner screening drums to rotate, the tea leaves are in a rolling screening and grading state through the sieve holes on the periphery of the inner screening drums. When the two groups of outer screening drums drive the tea leaves inside the outer screening drums to rotate, the tea leaf impurities are in a rolling filtering state through the sieve holes on the periphery of the outer screening drums.

[0009] Preferably, docking members are integrally formed on the peripheries of the two groups of inner screening drums and outer screening drums. Thread grooves are formed inside the docking members, and fixing bolts for fixing the inner screening drums and outer screening drums are threadedly connected inside the thread grooves.

[0010] Preferably, when the two groups of inner screening drums and outer screening drums are turned close to each other, the docking members on the two groups of inner screening drums and outer screening drums are in an assembled docking state.

[0011] Preferably, installation grooves are formed on the front and rear sides inside the mounting frame. Both ends of one group of inner screening drums are provided with drive shafts passing through the outer screening drums, and the periphery of the drive shafts is rotationally connected and matched with the inner side of the installation grooves.

[0012] Beneficial effects

[0013] The utility model provides a tea screening device for tea planting. It has the following beneficial effects:

[0014] 1. For the tea screening device for tea planting, in this article, after the inner screening drum is filled with tea materials, when the drive shaft drives the inner screening drum to rotate by an external drive device, the materials can be in a rolling and flipping screening state inside the inner screening drum, increasing the movement amplitude of the material screening. When the sieve holes on the surface of the inner screening drum are jammed with materials, when the jammed materials are flipped to the upper part by the inner screening drum, the materials can automatically fall off and continue the screening process. Moreover, at the position corresponding to the sieve holes outside the inner screening drum, a top feed shaft that can telescopically slide is provided in the limit sleeve. When the top feed shaft rotates to the upper position in cooperation with the inner screening drum, the top feed shaft can automatically move downward by gravity and insert into the sieve holes to eject the jammed materials, ensuring the throughness inside the sieve holes, so as to achieve the effect of enabling the tea materials to be normally filtered and screened, avoiding blockage, and improving the tea filtering and screening efficiency.

[0015] 2. For the tea screening device for tea planting, when the two groups of inner screening drums drive the tea inside the inner screening drums to rotate through the drive shaft, the tea is preliminarily screened and graded by rolling through the sieve holes on the periphery of the inner screening drums. The smaller tea leaves and foreign matters are first removed into the inner part of the outer screening drums. When the two groups of outer screening drums drive the tea after screening and filtration to rotate again, the impurities and foreign matters in the tea can be screened and removed through the sieve holes on the periphery of the outer screening drums, so as to achieve the effect of improving the tea filtering quality.

An outer sleeve of the screening inner drum 3 is provided with two sets of assembled and matched screening outer drums 4. Installation grooves 5 are formed on both the front and rear sides of the inner side of the mounting frame 1. Both ends of one set of screening inner drums 3 are installed with drive shafts 6 that penetrate the screening outer drums 4. The periphery of the drive shaft 6 is rotationally connected and matched with the inner side of the installation groove 5. The two sets of screening inner drums 3 and screening outer drums 4 are all movably connected and matched through hinges 13. Sieve holes 7 are formed on the peripheries of the screening inner drums 3 and screening outer drums 4. Position-limiting sleeves 8 are provided at positions corresponding to the sieve holes 7 on the periphery of the screening inner drums 3. A top material shaft 10 for top material cooperation is telescopically arranged inside the position-limiting sleeve 8. The periphery of the position-limiting sleeve 8 is supported and connected with the periphery of the screening inner drum 3 through a support mechanism 9. First limit members 11 and second limit members 12 are respectively installed at both ends of the top material shaft 10. Docking members 14 are integrally formed on the peripheries of the two sets of screening inner drums 3 and screening outer drums 4. Thread grooves 15 are formed inside the docking members 14. Fixing bolts 16 for fixing the screening inner drums 3 and screening outer drums 4 are threadedly connected inside the thread grooves 15.

[0026] Furthermore, when the screening inner drum 3 drives the tea inside the screening inner drum 3 to rotate, when the top material shaft 10 inside the position-limiting sleeve 8 rotates to the lower position in cooperation with the screening inner drum 3, the top material shaft 10 is in a telescopic sliding state away from the sieve hole 7, and the end of the top material shaft 10 is limited and supported by the second limit member 12 with the position-limiting sleeve 8.

[0027] Furthermore, when the top material shaft 10 inside the position-limiting sleeve 8 rotates to the upper position in cooperation with the screening inner drum 3, one end of the top material shaft 10 enters the sieve hole 7 and is in a top material state for the stuck tea.

[0028] Furthermore, when the two sets of screening inner drums 3 drive the tea inside the screening inner drums 3 to rotate, the tea is in a rolling screening and grading state through the sieve holes 7 on the periphery of the screening inner drums 3. When the two sets of screening outer drums 4 drive the tea inside the screening outer drums 4 to rotate, the tea impurities are in a rolling filtering state through the sieve holes 7 on the periphery of the screening outer drums 4.

[0030] The working principle of the present utility model:

[0031] After the tea materials are loaded inside the screening inner drum 3, when the driving shaft 6 is driven by an external driving device to drive the screening inner drum 3 to rotate, the materials can be in a rolling and flipping screening state inside the screening inner drum 3, increasing the movement amplitude of the material screening. When the sieve holes 7 on the surface of the screening inner drum 3 are blocked by the materials, when the blocked materials are flipped to the upper part by the screening inner drum 3, the materials can automatically fall off and continue the screening process. Moreover, at the position corresponding to the sieve holes 7 outside the screening inner drum 3, a top material shaft 10 that can telescopically slide is arranged in the limit sleeve 8. When the top material shaft 10 cooperates with the screening inner drum 3 to rotate to the upper position, the top material shaft 10 can automatically move downward by gravity and insert into the sieve holes 7 to eject the blocked materials, ensuring the throughness inside the sieve holes 7, so that the tea materials can be normally filtered and screened, avoiding blockage and improving the tea filtering and screening efficiency.
