DETAILED DESCRIPTION

[0024] The following will be combined with the attached Figure 1-6 The utility model is further described with examples.

[0025] This embodiment discloses a tea sorting machine.

[0026] Since the existing tea sorting machine uses a vibration mechanism to drive the tea leaves to vibrate and screen, but when the vibration mechanism drives the tea leaves to vibrate, the noise caused by the vibration is loud, which will increase the speed of loosening or damage of the parts inside the tea sorting machine, and bring greater noise to the workplace. In order to solve the above problems, reference is made to Figure 1-6 The present embodiment provides a tea sorting machine, comprising a frame 11, a sorting screen 16, a collecting box 18, and a motor 19 for driving the sorting screen 16 to swing back and forth. The two ends of the sorting screen 16 are a swinging end 30 and a rotating end 29 respectively. The swinging end 30 of the sorting screen 16 swings relative to the frame 11. The rotating end 29 of the sorting screen 16 is coaxially connected to the movable end of the motor 19. The fixed end of the motor 19 is connected to the frame 11. The bottom wall of the sorting screen 16 is provided with a tea outlet 17. The tea outlet 17 is arranged near the rotating end 29 of the sorting screen 16. The frame 11 is provided with a receiving plate 12. The collecting box 18 is detachably connected to the top surface of the receiving plate 12. The opening of the collecting box 18 is located at the lower side of the tea outlet 17. The tea leaves on the classification screen 16 are collected, and the movable end of the motor 19 drives the classification screen 16 to rotate, so that the swinging end 30 of the classification screen 16 swings, and the tea leaves are turned over on the swinging classification screen 16. If the turning tea leaves meet the screening conditions, they will pass through the classification screen 16 and be screened. The tea leaves on the classification screen 16 will gradually move toward the tea outlet 17 as the classification screen 16 swings, and finally fall into the collection box 18 through the tea outlet 17, finally realizing the graded screening of the tea leaves, reducing the vibration of the tea classifier, reducing the risk of looseness between components, slowing down the damage rate of components, reducing the noise during the operation of the tea classifier, and reducing the noise pollution caused by the equipment to the surrounding environment.

[0027] It should be noted that when the classification screen 16 swings, the height of the swinging end 30 of the classification screen 16 is greater than the height of the rotating end 29 of the classification screen 16, and the swinging angle of the classification screen 16 is preferably such that the classification screen 16 swings within a range of 5° to 12° with respect to the horizontal plane.

[0028] When the motor 19 drives the classification screen 16 to swing, the swinging end 30 of the classification screen 16 has the risk of instability. In order to solve the above problem, the swinging end 30 of the classification screen 16 of the present embodiment is provided with a sliding shaft, and the inner surface of the side wall of the frame 11 is recessed with a sliding groove 21. The annular wall of the sliding shaft is slidably connected to the inner wall of the sliding groove 21. The movable end of the motor 19 drives the classification screen 16 to swing, and the sliding shaft slides in the sliding groove 21. The opening shape of the sliding groove 21 is adapted to the sliding trajectory of the sliding shaft. The sliding groove 21 limits the sliding trajectory of the sliding shaft. The swinging end 30 of the classification screen 16 is limited by the sliding groove 21, so that the stability of the classification screen 16 when it swings is improved.

[0029] When the sliding shaft slides in the sliding groove 21, the friction between the sliding shaft and the sliding groove 21 is sliding friction, and the sliding friction will increase the instability between the sliding shaft and the sliding groove 21. In order to solve the above problem, the sliding shaft is rotatably provided with a rotating wheel 22, and the rotating wheel 22 is coaxially arranged with the sliding shaft, and the rotating wheel 22 is connected to the inner wall of the sliding groove 21. The rotating wheel 22 converts the sliding friction between the sliding shaft and the sliding groove 21 into rolling friction, thereby improving the stability of the connection between the sliding shaft and the sliding groove 21, thereby improving the stability of the classification screen 16 when it swings.

[0030] When the motor 19 drives the classification screen 16 to swing and screen the tea leaves, the tea leaves will jump, and the tea leaves located at the swinging end 30 of the classification screen 16 will jump with a larger amplitude and will be more easily thrown out of the classification screen 16, and the tea leaves will be thrown from the side of the classification screen 16 away from the motor 19, which will affect the screening of the tea leaves. Based on the above problems, the classification screen 16 of this embodiment is provided with a blocking portion 23, the bottom wall of the blocking portion 23 is connected to the top wall of the classification screen 16, and the blocking portion 23 is arranged near the swinging end 30 of the classification screen 16. When the motor 19 drives the classification screen 16 to swing, the tea leaves will shake on the classification screen 16, and the tea leaves on the classification screen 16 located on the side away from the motor 19 will have a larger swing amplitude. When the tea leaves here shake, they will abut against the blocking portion 23, thereby reducing the risk of the tea leaves falling from the classification screen 16 and improving the stability when screening the tea leaves.

[0031] When the tea leaves collide with the blocking portion 23, there is a risk that the tea leaves that collide with the blocking portion 23 will rebound and fall to the outside of the classification screen 16. To solve the above problem, the blocking portion 23 is set in an arc shape, and the blocking portion 23 is set in an arc shape from the top wall of the classification screen 16 gradually toward the rotating end 29 of the classification screen 16. Since the shape of the blocking portion 23 is an arc-shaped setting, when the bouncing tea leaves collide with the blocking portion 23, the tea leaves will collide with the blocking plate again after hitting the blocking portion 23, thereby limiting the position of the tea leaves, reducing the risk of the tea leaves falling from the classification screen 16, and improving the stability of tea leaf screening.

[0032] In order to increase the level of tea screening and improve the fineness of tea screening, in order to solve the above problems, the classification screen 16 is set in one or more groups. When multiple groups are set, the multiple groups of classification screens 16 are arranged vertically from top to bottom, and the radius of the screen holes of the multiple groups of classification screens 16 decreases from top to bottom. The tea is screened on the classification screen 16 in turn. The classification screen 16 located on the upper side separates larger tea leaves, and the classification screen 16 located on the lower side separates smaller tea leaves. Through the above arrangement, the tea classifier can screen the tea into multiple groups of tea leaves of different sizes, thereby improving the refinement of the tea screening by the tea classifier.

[0033] In order to enable the motor 19 to drive multiple groups of classification screens 16 to swing at the same time, the present embodiment also includes a driving wheel 24, a driven wheel 25, and a transmission belt 26. The driven wheel 25 is fixedly connected to the classification screen 16, and the driven wheel 25 is arranged near the rotating end 29 of the classification screen 16. The driving wheel 24 is connected to the movable end of the motor 19, and the transmission belt 26 is sleeved on the driven wheel 25 and the driving wheel 24, and is used to synchronously drive the multiple groups of classification screens 16 to swing. The movable end of the motor 19 rotates, thereby driving the driving wheel 24 to rotate. The rotating driving wheel 24 drives the driven wheel 25 to rotate through the transmission belt 26, thereby driving the classification screen 16 to swing, and the swinging end 30 of the classification screen 16 swings around the rotating end 29, so as to achieve the effect that the motor 19 synchronously drives the multiple groups of classification screens 16 and drives the multiple groups of classification screens 16 at the same time.

[0034] When the collecting box 18 is placed on the receiving plate 12 to collect tea leaves, its position may be affected by the swing of the classification screen 16 and change its position, thereby affecting the collection of tea leaves. To solve the above problem, the top wall of the receiving plate 12 of this embodiment is provided with a first magnetic component 27, and the outer surface of the side wall of the collecting box 18 is provided with a second magnetic component 28. The first magnetic component 27 and the second magnetic component 28 are mutually attracted to each other and are used to locate the position of the collecting box 18. When the collecting box 18 is placed on the receiving plate 12, the first magnetic component 27 and the second magnetic component 28 are mutually attracted to each other, thereby locking the stability of the collecting box 18. Through the above arrangement, the possibility of the position of the collecting box 18 changing is reduced, and the stability of the position of the collecting box 18 is improved.

[0035] A further solution is that the frame 11 includes a vertical plate 13 and a bottom plate 14, the bottom walls of the two groups of vertical plates 13 are vertically connected to the top wall of the bottom plate 14 at intervals, multiple groups of receiving plates 12 are vertically arranged in sequence and connected between the two groups of vertical plates 13, multiple groups of collecting boxes 18 are respectively connected to the top walls of the receiving plates 12, and the sliding grooves 21 are arranged on the sides of the vertical plates 13. Through the above arrangement, a position is provided for the collection box 18 to be placed, and the multiple groups of receiving plates 12 are vertically arranged in sequence and the receiving plates 12 are arranged at intervals to form multiple groups of grid-like spaces, which provide positions for placing the collection box 18.

[0036] A further solution is that the frame 11 includes a top plate 15, the top plate 15 is connected to the top walls of the two groups of vertical plates 13, the fixed end of the motor 19 is connected to the bottom surface of the top plate 15, the receiving plate 12 is provided with a clearance hole 32, the transmission belt 26 passes through the clearance hole 32 and is sleeved on the driving wheel 24 and the driven wheel 25, the top plate 15 provides an assembly position for the assembly of the motor 19, and the clearance hole 32 provides an assembly position for the assembly of the transmission belt 26, so that the motor 19 can drive the classification screen 16 to swing simultaneously through the transmission belt 26, thereby driving the tea leaves and then screening the tea leaves.

[0037] A further solution is that the side wall of the vertical plate 13 is provided with an observation hole 31 , and the observation hole 31 is arranged corresponding to the plurality of groups of classification screens 16 . The observation hole 31 is convenient for observing the shaking of the tea leaves on the classification screens 16 .

[0038] Among them, the rotating end 29 of the classification screen 16 is fixedly provided with a bearing shaft, which is coaxially connected to the driven wheel 25. The opposite side walls of the two sets of vertical plates 13 are provided with rotating holes, and the bearing shaft is rotatably connected to the rotating holes, which plays a supporting role in the rotation of the classification screen 16.

[0039] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
