Description

Technical Field

[0001] The present application relates to the technical field of tea leaf winnowing machines, and in particular to a tea leaf winnowing machine. Background Art

[0002] Tea, as a unique drink in China, is loved by the people. During the production process, the quality of tea needs to be graded. Generally, it is divided according to the degree of wholeness and brokenness of the leaves of the same type. Since the whole leaves have the largest mass and the tea powder has the smallest mass, in this process, a wind sorter is usually used for sorting, using wind power to screen tea leaves of different qualities.

[0003] In the prior art, when the tea sorting machine sorts tea leaves, after the tea leaves to be screened enter the air selection channel from the feed hopper, under the action of the blast hood, heavier impurities (such as sand and gravel, large branches and stems) are separated into the impurity collection frame, and the lighter tea dust passes through the material blocking net and is then separated into the tea dust collection bag, while most of the tea leaves fall directly into the lower hopper, and a small part of the tea leaves move forward with the tea dust until they are blocked by the material blocking net, and then move to the lower hopper under the action of gravity and are discharged, thereby effectively screening out normal tea leaves. However, when some tea leaves are fed into the sorting machine, they will condense and adhere together due to moisture and other reasons, causing the tea leaves to agglomerate. In this way, the agglomerated tea leaves cannot be thoroughly air-selected during air selection due to being in an agglomerated state, thereby reducing the air selection effect of the tea leaves. Therefore, a person skilled in the art provides a tea air sorting machine to solve the problems raised in the above background technology. Utility Model Content

A rotating component 6 for driving the rotating shaft 4 to rotate is provided on one side of the feed hopper 2, and the rotating component 6 is connected to the feed hopper 2 through a linkage component 7.

[0028] In this embodiment, the tea leaves are first conveyed to the air separation box 1 through the feed hopper 2. When the tea leaves are fed through the feed hopper 2, they first fall onto the guide plate 3. At the same time, the movement of the linkage component 7 drives the rotation of the rotating component 6, and the rotating component 6 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the breaking rod 5 to rotate. The breaking rod 5 can break up the tea leaves agglomerated on the guide plate 3 during its rotation, and then the tea leaves fall into the air separation box 1 for air separation, which facilitates the full air separation of the tea leaves, avoids incomplete air separation due to agglomeration of the tea leaves, and improves the air separation effect of the tea leaves.

[0029] In a further embodiment, Figure 2-4 As shown, the rotating assembly 6 includes driven wheels 61 respectively fixedly arranged at one end of two rotating shafts 4, one side of the feed hopper 2 is rotatably connected to two driving wheels 62, and the two driving wheels 62 are respectively connected to the driven wheels 61 through belts 63. The linkage assembly 7 includes meshing gears 71 respectively fixedly arranged on one side of the two driving wheels 62, a motor seat 72 is fixed on one side of the feed hopper 2, and a driving motor 73 fixed to the gear 71 is fixed on the top of the motor seat 72.

[0030] When tea leaves are fed through the feed hopper 2, under the movement of the driving motor 73, the meshing movement of the two gears 71 can drive the two driving wheels 62 to rotate in the opposite direction. The two driving wheels 62 drive the two driven wheels 61 to rotate in the opposite direction through the belts 63. The two driven wheels 61 drive the two rotating shafts 4 to rotate in the opposite direction, thereby driving the rotation of the breaking rod 5. The breaking rod 5 can be used to break up the tea leaves agglomerated on the guide plate 3 to avoid tea leaves agglomerating and affecting air selection, thereby facilitating the full air selection of the tea leaves and improving the air selection effect of the tea leaves.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, baffles 8 are interspersed and connected on both sides of the feed hopper 2, and connecting plates 9 are fixed on one side of the two baffles 8 located outside the feed hopper 2. Pull rods 10 are fixed on one end of the two connecting plates 9. The two pull rods 10 are connected to the feed hopper 2 through sliding components 11, and a swing component 12 is provided on one side of the feed hopper 2 to drive the pull rods 10 to move.

[0032] During the feeding process of tea leaves through the feed hopper 2, the movement of the swinging assembly 12 drives the pull rod 10 to reciprocate, and the pull rod 10 drives the connecting plate 9 to reciprocate, and the connecting plate 9 drives the baffle 8 to reciprocate. During the reciprocating movement of the baffle 8, the feed hopper 2 can be reciprocated and opened and closed, thereby facilitating the quantitative feeding of tea leaves through the feed hopper 2, avoiding excessive feeding of tea leaves that affects air selection, facilitating sufficient air selection of tea leaves, and improving the air selection effect of tea leaves.

[0034] During the feeding process of tea leaves through the feed hopper 2, the driving motor 73 works to drive the rotating shaft 4 and the breaking rod 5 to rotate, the driven wheel 61 drives the second connecting rod 122 to rotate, the second connecting rod 122 drives the movement of the first connecting rod 121, and the first connecting rod 121 drives the reciprocating motion of the pull rod 10. At the same time, with the cooperation of the slider 111 and the slide groove 112, the movement of the pull rod 10 is kept stable, the pull rod 10 drives the reciprocating motion of the connecting plate 9, thereby driving the reciprocating motion of the baffle 8, and the feed hopper 2 can be reciprocated. Open and close, it is convenient for the quantitative feeding and air selection of tea leaves, and the air selection effect of tea leaves is improved.

The tea leaves are broken up to avoid agglomeration and affect air selection, which facilitates sufficient air selection of the tea leaves and improves the air selection effect of the tea leaves. When the driven wheel 61 rotates, the second connecting rod 122 is driven to rotate, and the second connecting rod 122 drives the movement of the first connecting rod 121.
