Description

Technical Field

[0001] The invention relates to the technical field of tea production equipment, and in particular to a multi-stage sorting device for tea processing. Background Art

[0002] Tea is a popular beverage in the world, and the sorting process in its processing plays a vital role. The accuracy and efficiency of sorting are not only related to the quality and grade of tea, but also directly affect its market value. With the continuous development of the tea industry and the continuous improvement of consumers' quality requirements, the demand for tea sorting technology and equipment is becoming increasingly stringent. The traditional tea sorting method mainly relies on manual operation. Workers use vision and touch to carefully identify and classify tea to distinguish tea of ​​different sizes, shapes, colors and qualities.

[0003] However, there are many limitations to manual sorting. First, the efficiency of manual sorting is relatively low, and it is difficult to cope with the increasing production of tea. In order to maintain the production schedule, a lot of manpower and time costs are often required, which will undoubtedly greatly increase the production cost. Secondly, the quality stability of manual sorting is difficult to guarantee. Due to factors such as individual differences, work experience, and fatigue level of workers, the sorting results often fluctuate greatly, resulting in uneven tea quality. This not only affects the overall quality of the product, but also weakens the market competitiveness of tea and restricts the further development of the tea industry. Therefore, it is necessary to design a multi-stage sorting device for tea processing that is efficient, uniform, and can reduce tea damage. Summary of the invention

[0029] When it is necessary to sort the tea leaves in multiple levels, the staff first pours the tea leaves into the feed hopper 141, and then starts the driving assembly 11, which drives the rotating rod 10 to rotate, and the rotating rod 10 drives the screening drum 4 to rotate through the supporting frame 101, and the screening drum 4 drives the annular pouring ring 145 to rotate through the annular guide ring 5, and the tea leaves in the feed hopper 141 fall into the annular pouring ring 145. Since the two partitions 143 on the upper side and the annular pouring ring 145 form a fixed material area, the tea leaves at the bottom fall into the fixed material area, and the annular During the rotation of the pouring ring 145, when the drop opening of the annular pouring ring 145 faces upward, the tea leaves fall into the middle side of the annular pouring ring 145. As the cylindrical block 16 of the annular guide ring 5 rotates, the toggle rod 18 is driven to scatter the tea leaves. Since the middle side is inclined to the left, the scattered tea leaves slide into the screening cylinder 4. The rotating screening cylinder 4 gradually drives the tea leaves to flip and slide to the left. Tea leaves of different sizes are screened out through the circular holes of the screening cylinder 4. The isolation plate 1210 on the screen 128 distinguishes tea leaves of different sizes. When the annular guide ring 5 rotates, the gear ring 1312 is driven to rotate, the gear ring 1312 drives the pinion 138 to rotate, the pinion 138 drives the crank 139 to rotate, the crank 139 drives the slot plate 1311 to slide up and down through the sliding shaft 1310, and the crank 139 makes a circular motion with the pinion 138, and the sliding shaft 1310 can slide back and forth in the slot plate 1311, and the slot plate 1311 drives the cross plate 123 to move up and down, so that the entire screen 128 vibrates up and down. It is beneficial to screen out the tea leaves, and the tea leaves slowly slide backward to the collection frame. When the screen 128 moves downward, the sliding shaft 132 squeezes the inclined surface of the wedge block 131, and then the entire screen 128 slides backward along the straight slide rail 124 with the slider 125 through the sliding sleeve 126 and the moving rod 127. The second elastic member 135 is compressed, and the top rod 134 can also drive the screen 128 to shake up and down when it contacts the wave bar 133. The first elastic member 129 can keep the screen 128 finally reset. The device has a simple structure, can realize the segmented feeding of tea leaves, and quickly complete the spreading. At the same time, it can gradually and progressively sort the tea leaves entering the screening cylinder 4, and finally complete the multi-level sorting operation through the screening mechanism 12.
