Technical Field

[0001] The utility model relates to the technical field of tea drying, in particular to a tea drying machine which can automatically flatten tea leaves. Background Art

[0002] After the tea leaves are fried or steamed, they need to be spread out and dried using a drying machine before entering the next process to ensure the production quality of the tea leaves.

[0003] However, in the prior art, when the tea leaves are sent to the drying machine, due to the lack of a flattening mechanism, the tea leaves are easily locally piled up on the drying machine, thereby affecting its cooling and drying effect, and further affecting the quality of the tea leaves to a certain extent. In addition, the drying efficiency is low, which is not conducive to mass production and processing. Therefore, it is necessary to propose a drying machine that can automatically flatten the tea leaves to solve the above problems. Utility Model Content

[0006] By adopting the above technical solution, the tea leaves are poured flatly into the drying rack through the mobile feeding device, and the electric push rods on both sides are driven at the same time. The moving block drives the rotating rod to slide horizontally, thereby driving the gear at the end to move. Under the push of the rack, the gears rotate at the same time, thereby driving the rotating rod to move and rotate at the same time, so that the external pushing rack moves and rotates, thereby automatically flattening the tea leaves poured into the drying rack, and with the cooperation of the dehumidification mechanism, the tea leaves can be quickly dried.

[0007] The utility model is further configured as follows: the end of the rotating rod passes through the moving block and is rotatably connected thereto through a bearing, and brackets are installed at the four corners of the outer side of the drying rack.

[0008] By adopting the above technical solution, when the moving block pushes the rotating rod forward, the rotation of the rotating rod will not conflict with the movement of the moving block, and the bracket is used to support the equipment.

The setting of the filter can prevent impurities from entering and affecting the quality of the tea leaves, and can speed up the drying efficiency of the tea leaves.

[0023] The utility model is further configured as follows: the control component includes a third motor installed at the bottom of the dehumidification chamber, a worm is installed at the output end of the third motor, and a worm wheel matching the worm is installed at the outer side of the driven rod.

[0024] By adopting the above technical solution, the worm is driven by the third motor to push the two worm wheels to rotate synchronously, so that the driven rod drives the fan blades to rotate, and the fried green tea leaves are quickly dehumidified.

[0025] The beneficial effects of the utility model are:

[0026] 1. The utility model pours the roasted green tea leaves into a feed bin, breaks them up through a breaking roller, and then transports them to a drying rack through a conveyor belt. At the same time, the second motor controls the rotation of the screw rod, and under the restriction of the limit rod, the moving block slides synchronously, driving the feed bin to move left and right, and pouring the tea leaves evenly into the drying rack. Then, the electric push rods on both sides are driven, and the moving block drives the rotating rod to slide horizontally, thereby driving the gear at the end to move. Under the push of the rack, the gears rotate at the same time, thereby driving the rotating rod to move and rotate at the same time, so that the external pushing rack moves and rotates, thereby automatically flattening the tea leaves poured into the drying rack, and the device is convenient for quickly drying the tea leaves.

[0027] 2. In the utility model, after the tea leaves are evenly spread, the third motor drives the worm to push the two worm wheels to rotate synchronously, so that the driven rod drives the fan blades to rotate, and the fried green tea leaves are quickly dehumidified, which can greatly improve the drying efficiency of the tea leaves and make the device more suitable for batch production and processing.
