DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-4 As shown, an embodiment of the utility model provides a tea screening machine that is easy to maintain, including a screen box 1, an outer wall of one side of the screen box 1 is provided with two plug ports 2, an upper screen plate 3 and a lower screen plate 4 are respectively plugged into the two plug ports 2, an outer wall of one side of the upper screen plate 3 and the lower screen plate 4 are hinged with a pull ring 7, one side of the upper screen plate 3 and the lower screen plate 4 are provided with a baffle 5, the top of the baffle 5 is hinged to the screen box 1, a baffle 6 is fixed to the outer wall of one side of the screen box 1, the baffle 6 is adapted to the baffle 5, a base 10 is provided at the bottom of the screen box 1, an elastic support assembly 8 is fixed between the base 10 and the screen box 1, and a vibration motor 9 is fixed to the bottom outer wall of the screen box 1.

[0022] When the tea leaves are in the air, the teacup 3 and the bottom sieve 4 are in the air, and the tea leaves 3 are in the air, and the tea leaves 3 are in the air. The baffle plates 5 are adapted to each other. When the upper sieve plate 3 and the lower sieve plate 4 need to be taken out, the baffle plate 5 is rotated to the stopper 6. The stopper 6 can block the downward rotation of the baffle plate 5. At this time, the baffle plate 5 does not block the upper sieve plate 3 and the lower sieve plate 4. A base 10 is provided at the bottom of the screen box 1. An elastic support assembly 8 is fixed between the base 10 and the screen box 1. The elastic support assembly 8 elastically supports the screen box 1. A vibration motor 9 is fixed to the bottom outer wall of the screen box 1. The vibration motor 9 drives the screen box 1 to vibrate when working. The baffle plates 5 block the upper sieve plates 3 and the lower sieve plates 4, so that the upper sieve plates 3 and the lower sieve plates 4 are more stable when installed inside the screen box 1. The baffle plates 5 are blocked by the stopper 6, so that all baffle plates 5 can simultaneously remain unblocked from the upper sieve plates 3 and the lower sieve plates 4, thereby making it more convenient to take out the upper sieve plates 3 and the lower sieve plates 4.

[0023] The utility model provides a tea screening machine which is easy to maintain. The upper sieve plate 3 and the lower sieve plate 4 are movably connected to the inside of the sieve box 1, so that the upper sieve plate 3 and the lower sieve plate 4 can be conveniently pulled out for cleaning when cleaning is needed, thereby achieving the effect of more convenient maintenance of the tea screening machine. In addition, the cooperation of the upper sieve plate 3 and the lower sieve plate 4 can distinguish broken tea leaves, large leaves and small leaves, so that the screening effect of the tea leaves is better.

[0024] In another embodiment provided by the utility model, a slide rail 14 is fixed to the inner wall of the screen box 1, and a slide groove 15 is opened on the outer walls of the upper screen plate 3 and the lower screen plate 4. The upper screen plate 3 and the lower screen plate 4 are slidably connected to the slide rail 14 through the slide groove 15, so that the upper screen plate 3 and the lower screen plate 4 can be slidably connected to the screen box 1, so that the upper screen plate 3 and the lower screen plate 4 can be inserted into the screen box 1 more smoothly.

[0025] In another embodiment provided by the utility model, an upper discharge hopper 12 and a middle discharge hopper 22 are respectively fixed to the outer wall of one side of the screen box 1, and the upper discharge hopper 12 and the middle discharge hopper 22 are respectively adapted to the upper screen plate 3 and the lower screen plate 4, so that as the screen box 1 vibrates, small leaves and broken tea pass through the upper screen plate 3 and fall on the lower screen plate 4, and larger leaves slide from the upper screen plate 3 to the upper discharge hopper 12 and flow out as the screen box 1 vibrates; the broken tea passes through the lower screen plate 4 and falls on the bottom inner wall of the screen box 1, and flows out from the lower discharge hopper 13 as the screen box 1 vibrates, and the small leaves flow out from the middle discharge hopper 22; a feed hopper 11 is fixed to the top outer wall of the screen box 1, and the tea leaves to be screened are added to the screen box 1 from the feed hopper 11, and a lower discharge hopper 13 is fixed to the bottom outer wall of the screen box 1, and the broken tea flows out from the discharge hopper 13.

[0026] In another embodiment provided by the utility model, the elastic support assembly 8 includes a guide sleeve 16 fixed to the base 10, the guide sleeve 16 is internally slidably connected with a sliding column 18, a guide column 17 is fixed to the top outer wall of the sliding column 18, the top of the guide column 17 extends to the outside of the guide sleeve 16 and is fixed to the screen box 1, and a spring 21 located inside the guide sleeve 16 is provided at the bottom of the sliding column 18, and the spring 21 elastically supports the sliding column 18; a groove 20 is opened on the outer wall of one side of the sliding column 18, and a graphite block 19 is embedded in the outer wall of the sliding column 18, and the sliding of the sliding column 18 is lubricated by the arranged graphite block 19, and the upper and lower parts of the sliding column 18 can be connected through the groove 20 to prevent the movement of the sliding column 18 from being obstructed, thereby making the elastic support assembly 8 more effective when in use and making the screen box 1 more reliable when vibrating.

[0027] Working principle: when in use, the entire screen box 1 is driven to vibrate by the vibration motor 9, and then the tea leaves to be screened are poured from the feed hopper 11 into the interior of the screen box 1, and as the screen box 1 vibrates, the small leaves and broken tea leaves pass through the upper screen plate 3 and fall on the lower screen plate 4, and the larger leaves slide from the upper screen plate 3 to the upper discharge hopper 12 to flow out as the screen box 1 vibrates; the broken tea leaves pass through the lower screen plate 4 and fall on the bottom inner wall of the screen box 1, and flow out from the lower discharge hopper 13 as the tea leaves vibrate, and the small leaves flow out from the middle discharge hopper 22; when it is necessary to maintain and clean the tea leaves blocked on the upper and lower screen plates 3 and 4, the baffle plate 5 is rotated so that the block 6 blocks the baffle plate 5 to prevent the baffle plate 5 from continuing to rotate. At this time, the baffle plate 5 does not block the upper and lower screen plates 3 and 4, and then the upper and lower screen plates 3 and 4 are pulled out from the interior of the screen box 1 through the pull ring 7, so that the upper and lower screen plates 3 and 4 of the screening machine can be conveniently cleaned and maintained.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
