Detailed Implementation
[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. Example
[0019] Please see Figures 1-5 This utility model discloses a tea sieving machine, comprising a sieving hopper 1 and an L-shaped support 8. The bottom of the sieving hopper 1 is connected to a material inlet 2. A material cover 3 is mounted on the top of the sieving hopper 1 via a hinged rotating cover. A locking buckle 4 is provided between the material cover 3 and the front end of the sieving hopper 1. A screen 5 is fixedly connected to the lower part of the interior of the sieving hopper 1. Both ends of the sieving hopper 1 are fixedly provided with locking grooves 6, and each set of locking grooves 6 is screwed with a knob bolt 7. A collection tray 9 is placed on the L-shaped support 8, positioned below the material inlet 2. A dual-shaft motor 10 is fixedly mounted on the L-shaped support 8, and drive shafts 11 are fixedly connected to both output ends of the dual-shaft motor 10. Two sets of drive shafts 11 are each fixedly fitted with cams 12. Two sets of T-shaped guide rods 13 are symmetrically slidably mounted on the L-shaped bracket 8. The front ends of the two sets of T-shaped guide rods 13 are fixedly connected to a C-shaped connecting frame 14. The C-shaped connecting frame 14 is symmetrically provided with two sets of positioning screw holes. The screening hopper 1 is detachably mounted on the C-shaped connecting frame 14 through the cooperation of the knob bolts 7 on the two sets of buckle grooves 6 with the positioning screw holes. Springs 15 are fitted on both sets of T-shaped guide rods 13, and the two ends of the springs 15 are fixedly connected to the C-shaped connecting frame 14 and the L-shaped bracket 8 respectively. A top plate 16 is fixedly mounted in the middle of the right end of the C-shaped connecting frame 14. The two sets of cams 12 All are in contact with the right end of the top plate 16. In use, the tea leaves to be sieved are placed into the sieve hopper 1, and the material cover 3 is closed using the lock 4. Then, the dual-shaft motor 10 is started, causing the dual-shaft motor 10 to drive the cam 12 to rotate via the transmission shaft 11. The rotation of the cam 12, under the reset action of the spring 15, causes the cam 12 to drive the C-shaped connecting frame 14 to oscillate back and forth through the top plate 16. This, in turn, causes the C-shaped connecting frame 14 to oscillate back and forth through its connection with the latch groove 6, thus causing the sieve hopper 1 to oscillate back and forth. This repeated oscillation of the sieve hopper 1 causes tea dust and tea fragments to sink to the bottom of the tea leaves and pass through the sieve. 5. The tea leaves fall into the bottom of the screening hopper 1 and are then discharged through the material outlet 2 into the collection tray 9 below. The collection tray 9 collects the screened tea ash and tea leaves, while the screened tea leaves remain in the screening hopper 1. This prevents tea ash and tea leaves from being mixed into the tea leaves. After screening, the knob bolt 7 is unscrewed from the positioning screw hole on the C-shaped connecting frame 14. Then, the retaining groove 6 can be slid off the C-shaped connecting frame 14, and the tea leaves in the screening hopper 1 can be poured out. This effectively prevents tea ash and tea leaves from being mixed into the tea leaves, improves the screening effect of the tea leaves, avoids affecting the quality of the tea leaves, and improves practicality.
[0020] The bottom end of the L-shaped support 8 is fixedly provided with four groups of universal wheels 17 symmetrically, and brake pads are arranged on the four groups of universal wheels 17.
[0021] Two groups of limiting plates 18 are fixedly connected to the inner side of the L-shaped support 8 symmetrically, and the left and right ends of the collecting disc 9 abut against the inner side of the two groups of limiting plates 18 respectively.
[0022] An observation window 19 is fixedly arranged in the observation opening in the top of the material cover 3.
[0023] Two groups of guide holes are arranged on the L-shaped support 8 symmetrically, and a sliding sleeve 20 is fixedly arranged in each of the two groups of guide holes.
[0024] The working principle of the tea shaking and screening machine is as follows: when the machine is used, the tea to be screened is put into the screening hopper 1, the material cover 3 is closed through the lock buckle 4, then the double-shaft motor 10 is started, the double-shaft motor 10 drives the transmission shaft 11 to drive the cam 12 to rotate, the cam 12 drives the top plate 16 to reciprocatingly shake the U-shaped connecting frame 14 left and right under the reset action of the spring 15, the U-shaped connecting frame 14 drives the screening hopper 1 to reciprocatingly shake left and right through the connection with the buckle groove 6, the tea dust and tea crumbs in the tea fall into the bottom of the tea through the reciprocating shaking of the screening hopper 1 and fall into the bottom of the screening hopper 1 through the screen 5, then the tea dust and tea crumbs are discharged to the collecting disc 9 below through the material port 2, the tea dust and tea crumbs screened out are collected through the collecting disc 9, and the screened tea is left in the screening hopper 1, so that the tea dust and tea crumbs are not mixed into the tea, after the screening is completed, the knob bolt 7 is unscrewed from the positioning screw hole in the U-shaped connecting frame 14, then the buckle groove 6 is slid off and removed from the U-shaped connecting frame 14, and then the tea in the screening hopper 1 is poured out.
[0025] The installation mode, connection mode or setting mode of the tea shaking and screening machine are all common mechanical modes, and as long as the beneficial effects can be achieved, the implementation can be carried out.
[0026] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present application.
