Description

Technical Field

[0001] The utility model relates to the technical field of tea drying, in particular to a dynamic continuous drum drying device. Background Art

[0002] The dynamic continuous drum drying device is a device used for drying tea leaves. It usually consists of a long drum with a heat source and a hot air circulation system inside the drum to provide heat and air flow to dry the tea leaves.

[0003] The existing drum drying device adds the rolled tea leaves into an elevator, lifts the tea leaves and drops them into a funnel at one end of the drying device. A round tube is provided at the bottom of the funnel and is connected to the inside of the drum. The tea leaves are pushed forward by the rotation of the spiral blades in the round tube, so that the tea leaves are continuously added to the drum dryer for drying. However, when the tea leaves enter the round tube and are pushed forward by the rotating spiral blades, the tea leaves in contact with the outer side of the spiral blades are squeezed by the round tube and the spiral blades, resulting in part of the tea leaves being crushed by the squeezing force generated by the rotation. A large amount of debris is produced after drying, affecting the quality of the tea leaves. Utility Model Content

[0004] The purpose of the utility model is to provide a dynamic continuous drum drying device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dynamic continuous drum drying device, comprising a dryer and an elevator, a feeding shell is fixedly installed at one end of the dryer, a rotating chamber is fixedly installed on the inner wall of the feeding shell, a feeding roller is rotatably connected to the inner wall of the rotating chamber, a containing groove is provided on the outer wall of the feeding roller, a feeding plate is fixedly installed on one side of the rotating chamber, a funnel is fixedly installed on the top of the feeding shell, a pulley is fixedly installed on one end of the feeding roller, a motor is fixedly installed on the top of the feeding shell, a first belt is connected to the rotating shaft of the motor and the tooth groove of the pulley, one side of the elevator is fixedly installed at one end of the dryer, and the discharge end of the elevator is directly above the funnel.

[0006] By adopting the above technical solution, the elevator conveys the tea leaves to the top of the funnel and drops them into the containing trough. The motor drives the first belt and the pulley to rotate, so that the feeding roller rotates to rotate the containing trough containing the tea leaves to one side of the feeding plate. The tea leaves will fall onto the feeding plate and slide into the dryer for drying.

[0007] Preferably, the inner wall of the feeding shell at one end of the feeding plate is rotatably connected to a pushing roller, one end of the pushing roller is fixedly installed with a gear, one side of the dryer is fixedly connected to a fixing plate, the inner wall of the fixing plate is rotatably connected to a gear shaft, the outer wall of the gear shaft and one end of the feeding roller are transmission-connected to a second belt, and the gear shaft is meshingly connected to the gear.

[0008] By adopting the above technical solution, the gear shaft is driven to rotate by the second belt, and the gear shaft drives the meshing gear to rotate, so that the push roller can rotate to push part of the tea leaves that have not slipped off into the interior of the dryer for drying.

[0017] Preferably, the width of the cleaning groove is the same as the width of the containing groove, and a plurality of holes are formed on the outer wall of the protective plate.

[0018] By adopting the above technical solution, the width of the cleaning groove is the same as the width of the holding groove, so that all the tea leaves stuck in the holding groove can be directly cleaned during cleaning, thereby improving the efficiency of cleaning the tea leaves. When holes are opened on the surface of the protective plate to play a ventilating role, it is also possible to observe through the holes whether there are tea leaves stuck inside.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) The tea leaves are conveyed to the top of the hopper by an elevator and fall into the holding trough. The motor is started to drive the first belt and the pulley to rotate, so that the feeding roller rotates to rotate the holding trough containing the tea leaves to one side of the feeding plate. The tea leaves fall onto the feeding plate and slide into the dryer for drying. This structure reduces the problem of broken tea leaves in the prior art during the feeding process, keeps the shape of the tea leaves intact after drying, and improves the quality of the tea leaves after drying.

[0021] (2) The feeding roller can rotate to drive the second belt to rotate, which in turn drives the gear shaft to rotate.
