Tea screening device for preliminary screening according to leaf shape

Technical field

The present invention relates to the technical field of screening devices, in particular to a tea screening device that performs preliminary screening according to the shape of leaves.

Background technique

Tea-making technology has existed and developed in our country for thousands of years. With the continuous expansion of the tea product market, in order to improve production efficiency, people have begun to find machines that can replace humans.

The tea picker can replace manual tea picking. When in use, the tea picker is swiped across the top of the tea tree, and the sprouts at the tip of the tea branches are cut into the tea picker through the rapidly rotating blade at the opening, and the blade that rotates in the process may be Some detached old leaves and young shoots will be sent into the tea picker together, so that the old leaves are mixed in the young shoots, which will affect the quality of tea. At the same time, in the later stage of sorting, it is necessary to manually separate the old leaves from the young leaves. ，Waste a lot of human resources and increase the cost of production.

In order to solve the above problems, the inventor proposed a tea screening device that performs preliminary screening according to the shape of the leaves, which has the advantage of screening and sorting tea leaves, and avoids the influence of the mixing of young leaves and old leaves during tea picking on the finished tea products. The quality problem has improved the quality of tea, and at the same time, the manual secondary selection is omitted, which saves a certain amount of working time and improves the efficiency of production.

An outlet 18 is provided on the outside of the classification tube 17, and the separation table 4 is movable above. A collection box 19 is connected, and a pick rod 20 is movably connected to the left side of the top of the collection box 19.

among them:

a. The width of the transmission slot 2 is no more than one centimeter. The tea-dial shaft 3 rotates clockwise. The tea-dial shaft 3 is equipped with eight dials. The specifications and dimensions of the eight dials are the same. The axis is evenly distributed for reference.

b. A torsion spring is installed at the connection between the rotating rod 7 and the shovel plate 8. The twisting keeps the angle between the rotating rod 7 and the shovel plate 8 at ninety degrees. The bottom surface of the groove 9 is inclined backward. The rotating rod 7 consists of two specifications. Consistent rod-shaped structure, two rod-shaped structures are perpendicular to each other and hinged at the center.

c. The sorting pipe 17 is in an inclined state, and the inclination angle is not less than 30 degrees, the length of the outlet 18 gradually becomes longer to the right, the number of shovel plates 8 is four, and the four shovel plates 8 are respectively two rods with the rotating rod 7 The two ends of the shaped structure are movably connected.

among them:

d. The adjusting rod 16 is located at the center of the adjusting cavity 15, the length of the through groove 14 is greater than the length of the groove 9, the height of the through groove 14 is less than the thickness of the shovel plate 8, the pick rod 20 is located on the left side of the top of the collection box 19 and The collection box 19 is in a movable hinged state.

e. The bottom surface of the reset slot 11 is set to be an inclined surface, and the horizontal height of the reset slot 11 is the same as that of the through slot 14.

When in use, pour the collected tea leaves on the conveyor belt 1, and the tea dial shaft 3 is constantly turned clockwise to move the tea leaves into the conveyor slot 2, so that the tea leaves move to the right along the conveyor slot 2, due to the width of the conveyor slot 2. It is narrower, and the tea leaves in the conveying trough 3 are parallel to it.

When the tea leaves pass under the separation table 4, as shown in Fig. 3, the rotating shaft drives the shovel plate 8 to rotate clockwise through the rotating rod 7 to scoop up the tea leaves in the conveying trough 2 to fall into the groove 9, and the shovel plate 8 continues to rotate. To the state of Figure 1, the end of the shovel plate 8 is in contact with the slider 13, pushing the slider 13 to compress the return spring 12 to slide upward in the chute 10. Since the elastic force of the return spring 12 is greater than the elastic force of the torsion spring where the shovel plate 8 connects and rotates, the shovel The angle between the plate 8 and the rotating rod 7 gradually increases.

The shovel plate 8 gradually rotates so as to be parallel to the trough 14, and the tea leaves are elongated and completely located in the trough 9. At this time, it can slide into the trough 14 along the inclined bottom surface of the trough 9, and the old leaves are flat, and It has a large area and extends out of the groove 9 and folds on its side.
