Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Example 1
[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a chain conveyor for preventing jamming of tea leaves, comprising a housing 1 and a conveying section 2.
[0034] The outer casing 1 has an inlet 101 at the top and an outlet 102 at the bottom. A feeding belt 103 is located on the side of the outer casing 1. The interior of the outer casing 1 houses components such as heating elements for drying, a fan, and a temperature sensor. The working principle of the tea chain plate dryer is to continuously dry tea leaves by using a steel chain plate as a conveyor belt. Specifically, the chain plate dryer uses electric heating, steam heating, or hot air heating to heat the air, and then allows the hot air to flow through the tea leaves, thereby achieving rapid drying. This is existing technology and will not be elaborated further below.
[0035] The conveying unit 2 is located inside the outer casing 1. The conveying unit 2 has a drive shaft 201 that is longitudinally rotatably arranged inside the outer casing 1. A driven shaft 204 is longitudinally rotatably arranged inside the conveying unit 2. A transmission chain 203 is externally meshed with the drive shaft 201. The transmission chain 203 is meshed with the driven shaft 204. Several chain plate bodies 206 are arranged on the side of the transmission chain 203. A rubber strip 208 is provided on the top surface of the chain plate body 206. The rubber strip 208 abuts against the adjacent chain plate body 206 to fill the gaps between the chain plate bodies 206. Through the dynamic filling effect of the rubber strip 208, the gap changes between multiple chain plate bodies 206 can be automatically compensated during the movement of the chain plate bodies 206, preventing small tea leaves or tea dust from getting stuck in the gaps of the chain plates. At the same time, the elasticity of the rubber strip 208 can buffer the mechanical impact during the conveying of tea leaves.
[0036] Example 2
[0037] Please see Figure 4 , Figure 5 , Figure 6 and Figure 7 This embodiment provides a technical solution: a chain conveyor for preventing jamming of tea leaves, comprising a housing 1 and a conveying section 2.
[0038] The conveying section 2 is provided in three sets. The three sets of conveying sections 2 are arranged horizontally and parallel inside the outer shell 1. The three sets of conveying sections 2 are arranged in an "S"-shaped meandering manner. Through the passage with a meandering shape, the time of tea leaves inside the outer shell 1 can be extended, thereby improving the drying efficiency.
[0039] A motor 202 is fixedly installed on the side of the outer casing 1. The fixing method is an existing detachable fixing, such as bolt connection, snap connection, etc. The working principle of the motor 202 is based on electromagnetic induction and Lorentz force. The motor 202 generates force in the magnetic field through current, thereby driving mechanical movement. The above is the existing technology and will not be repeated below. When selecting the model, its power should be selected to match the needs of the device to ensure that the object to be driven is driven. The output end of the motor 202 is connected to the drive shaft 201, and the drive shaft 201 can be driven to rotate inside the outer casing 1 by the motor 202.
[0040] The drive shaft 201 has meshing teeth at both ends and is connected to the transmission chain 203. The driven shaft 204 also has meshing teeth at both ends and is connected to the transmission chain 203. This allows the double-end synchronous meshing structure to eliminate the chain plate deviation caused by single-sided transmission and improve the stability when conveying tea.
[0041] Two transmission chains 203 are provided, and several chain plate bodies 206 are arranged longitudinally in the middle of the two transmission chains 203, which allows the double chain support structure to make the chain plate bodies 206 more evenly stressed.
[0042] A slot 207 is longitudinally provided on the top of the chain plate body 206. The rubber strip 208 is embedded in the slot 207 and is longitudinally slidably connected to the chain plate body 206. The connection between the rubber strip 208 and the chain plate body 206 is wedge-shaped, and the rubber strip 208 can be installed on the top of the chain plate body 206 by sliding.
[0043] A cleaning roller 209 is longitudinally rotatably arranged inside the outer casing 1. A gear b210 is provided at one end of the cleaning roller 209, and a gear a205 is provided at one end of the driven shaft 204. The gear a205 meshes with the gear b210. Through the transmission of the gears, the driven shaft 204 can drive the cleaning roller 209 to rotate together when it rotates.
[0044] Brush bristles 211 are arranged around the outer side of the cleaning roller 209. The cleaning roller 209 is located directly below the driven shaft 204. The brush bristles 211 abut against the chain plate body 206. The rotating cleaning roller 209 can drive the brush bristles 211 to rotate, thereby brushing off the tea leaves and tea dust adhering to the surface of the chain plate body 206.
[0045] Working principle: First, the device is powered on. Then, the tea leaves to be dried are evenly spread on the first-layer chain plate body 206 through the feed inlet 101 via the feeding belt 103. The heating element heats the air to the set temperature. When the chain plate moves, the rubber strip 208 slides slightly within the slot 207 due to its wedge-shaped connection, filling the gap between the chain plates by 1-2mm in real time to prevent broken tea leaves from seeping in. The sensor monitors the temperature in real time and adjusts the power of the heating element accordingly. The motor 202 drives the drive shaft 201 to rotate, which in turn drives the chain plate body 206 to move via the double transmission chain 203. When the tea leaves fall from the upper chain plate to the lower layer, the cleaning roller 209 works synchronously. Gear a 205 drives gear b 210 to rotate, causing the brush bristles 211 to rotate and brush the side of the chain plate body 206 to remove residual tea dust.
