Description

Technical Field

[0001] The utility model relates to the technical field of tea wind selection, in particular to an adjustable sorting plate mechanism of a tea wind sorting machine. Background Art

[0002] Different teas require different production processes during production, but in the process of tea production, the tea leaves need to be processed from wet to dry. In the process of drying, it is inevitable that defective products such as broken tea leaves will appear, which will affect the quality of the tea leaves. After the tea leaves are produced, it is usually necessary to use a tea winnowing machine to blow out the broken tea leaves and separate tea leaves of different sizes, so as to improve the yield rate of the tea leaves and grade the tea leaves at the same time.

[0003] However, different teas have different volumes, for example, Taiping Houkui and Maojian, both of which are very large and very flat. Therefore, when affected by wind, large pieces of Taiping Houkui will fly to a location far away from the wind source, while Maojian, which is cylindrical in shape and smaller in volume, will land closer to the wind source when affected by wind. However, the sorting mechanism of the tea air sorting machine in the prior art is difficult to adjust at a large angle, which makes it impossible for the device to effectively air sort larger tea types, thereby reducing the applicability of the device. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide an adjustable sorting plate mechanism for a tea air sorting machine, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A tea wind sorting machine has an adjustable sorting plate mechanism, comprising a sorting trough, a fixed ring is arranged at one end inside the sorting trough, a plurality of evenly distributed sorting rods are arranged on one side of the fixed ring, a plurality of expansion rings are jointly sleeved on the middle parts of the sorting rods, an isolation plate is arranged at a position inside the sorting trough corresponding to the expansion ring, and one of the expansion rings is located at the end of the sorting rod away from the fixed ring, an expansion mechanism is arranged at the end of the sorting rod away from the fixed ring, a feed trough is arranged at the end of the fixed ring away from the sorting rod, and a wind tube is arranged at one end of the feed trough.

[0007] By adopting the above technical scheme, when in use, tea leaves are put into the inside of the feed trough and blown toward one end of the sorting rod through the setting of the wind tube, so that different tea leaves fall on different positions of the sorting rod, thereby achieving the effect of grading and screening the tea leaves. At the same time, one end of the sorting rod is expanded by the setting of the expansion mechanism, so that the distance between two adjacent sorting rods changes, thereby achieving the change of the distance between the sorting rods away from the end of the wind tube, thereby achieving the effect of screening tea leaves with large volume differences.

[0008] In a preferred example, the utility model can be further configured as follows: the expansion ring includes a first ball valve sleeved on the middle part of the sorting rod, a fixing plate sleeved on the outer surface of the first ball valve, and outer sleeves for connecting two adjacent fixing plates are provided on both sides of the fixing plate.

[0009] By adopting the above technical solution, air is injected into the outer sleeve and the two positioning plates are pushed toward both sides by the air, thereby changing the distance between two adjacent sorting rods, and improving the flexibility of the sorting rods by setting the first ball valve.

[0010] In a preferred example, the utility model can be further configured as follows: the expansion mechanism includes a positioning ring located at one end inside the sorting trough, a positioning mechanism connected to the sorting rod is provided on one side of the interior of the positioning ring, a connecting pipe connected to the outer sleeve is provided at a position inside the positioning ring corresponding to the outer sleeve, and a compression piston is provided on one side of the positioning ring.

[0011] By adopting the above technical solution, the air inside the positioning ring is pushed by the compression piston, so that the air enters the interior of the outer sleeve through the connecting pipe, thereby pushing the fixed plates on both sides inside the outer sleeve to move, thereby changing the distance between two adjacent sorting rods, and improving the stability of the sorting rod when moving by setting the positioning mechanism.

[0012] In a preferred example, the utility model can be further configured as follows: a screw rod is disposed on one side of the interior of the positioning ring, and a thread groove meshing with the screw rod is disposed on the upper end of the compression piston.

[0013] By adopting the above technical solution, the compression piston is moved by the rotation of the screw in cooperation with the thread groove, thereby squeezing or extracting the air inside the positioning ring, thereby controlling the movement of the fixed plates on both sides of the outer sleeve.

[0014] In a preferred example, the utility model can be further configured as follows: the positioning mechanism includes a connecting piece connected to the end of the sorting rod, a second ball valve rotatably connected is embedded in the middle of the connecting piece, and a guide rod connected to the inner wall of the positioning ring is provided in the middle of the second ball valve.

[0015] By adopting the above technical solution, the second ball valve is installed by setting the connecting piece, and the guide rod is connected to the second ball valve to achieve the effect of positioning the sorting rod.

[0016] In a preferred example, the utility model can be further configured as follows: an air bag is provided inside the isolation plate and sleeved on the outer peripheral side of the expansion ring.

[0017] By adopting the above technical solution, the airbag is arranged to ensure that there is no gap at the contact position between the isolation plate and the expansion ring, thereby preventing the tea leaves from mixing with each other through the gap between the isolation plate and the expansion ring.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] 1. The tea air sorting machine can adjust the sorting plate mechanism, and the air inside the positioning ring is pushed by the compression piston, so that the air enters the inner part of the outer sleeve through the connecting pipe, thereby pushing the fixed plates on both sides of the inner part of the outer sleeve to move, so that the distance between two adjacent sorting rods is changed, so that the distance between the sorting rods away from the end of the air cylinder is changed, thereby achieving the effect of screening different types of tea with large volume differences, and effectively improving the applicability of the device;

[0020] 2. The tea wind sorting machine has an adjustable sorting plate mechanism. Tea leaves are put into the feed trough and blown toward one end of the sorting rod through the wind tube, so that different tea leaves fall on different positions of the sorting rod, thereby achieving the effect of grading and screening the tea leaves.
