[0010] A further improvement of this utility model is that a guide hopper is fixedly installed at the top of the inside of the cooling box, and a drive roller is rotatably installed on the inner wall of the output end of the guide hopper. The rotation of the drive roller can prevent tea leaves from clogging at the output end of the guide hopper.

[0011] A further improvement of this utility model is that the screening unit includes a screening screen plate movably installed on the bottom of the cooling box, and limit slide rods are movably inserted around the screen plate, so that the screening screen plate can screen the tea leaves.

[0012] A further improvement of this utility model is that a fixing block is fixedly installed on the bottom end of the limiting slide rod, the fixing block is fixedly installed on the bottom inner wall of the cooling box, and a return spring is movably sleeved on the outer surface of the limiting slide rod below the screening screen plate and above the fixing block.

[0013] A further improvement of this utility model is that: an inclined plate is provided at the bottom of the interior of the cooling box, and the other end of the inclined plate extends to the bottom of the interior of the dust collection tank. The inclined plate allows impurities at the screening point to enter the dust collection tank in an inclined direction.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a cooling air separation device for tea production. By setting a motor to drive the drive wheel, the drive rod drives the fan blades to rotate at a constant speed. The rotation of the fan blades generates wind power, which facilitates rapid cooling of the tea.

[0017] 2. This utility model provides a cooling air separation device for tea production. By setting a guide hopper, the tea leaves can be pushed downwards in small amounts multiple times, which further improves the cooling efficiency. The rotation of the drive roller can prevent the tea leaves from clogging the output end and promote smooth feeding.

[0018] 3. This utility model provides a cooling air separation device for tea production. By setting a screening screen plate to screen the tea, impurities and broken leaves are separated. The rotation of the driving wheel drives the transmission belt to make the driven wheel follow. When the driven wheel rotates, it drives the extrusion rod to rotate and press against the top of the contact plate. The contact plate is subjected to the extrusion force, which causes the screening screen plate to move downward and slide on the outer surface of the limiting slide rod, and presses the return spring. When the extrusion rod rotates away, the contact plate loses the extrusion force and rebounds to its original position under the elastic reaction force of the return spring. Thus, the screening screen plate realizes up and down reciprocating motion, which further promotes the screening rate. Attached Figure Description

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.

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model provides a cooling air separation device for tea production, including a cooling air separation device body 1. The cooling air separation device body 1 includes a cooling box 2. A dust guide box 3 is fixedly installed on the right side of the cooling box 2. A dust collection trough 4 is provided on the bottom end of the dust guide box 3. A discharge port 21 is fixedly installed on the front bottom end of the cooling box 2. A cooling unit is provided inside the cooling box 2. A screening unit is provided at the bottom end of the cooling box 2. A guide hopper 27 is fixedly installed at the top inside the cooling box 2. A drive roller 28 is rotatably installed on the inner wall of the output end of the guide hopper 27.

[0028] Furthermore, the guide hopper 27 enables the tea leaves to flow downwards in small amounts multiple times, and the rotation of the drive roller 28 helps prevent the tea leaves from clogging at the output end.

[0029] Example 2

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the cooling unit includes a through groove on the left side inside the cooling box 2, a bracket 22 is fixedly installed at the top of the left outer surface of the cooling box 2, a motor 23 is fixedly installed on the inner side of the bracket 22, a drive wheel 24 is fixedly installed on the output end of the motor 23, a drive rod 25 is fixedly installed on the output end of the drive wheel 24, and the other end of the drive rod 25 passes through the left through groove of the cooling box 2 and is fixedly sleeved with a fan blade 26.

[0031] Furthermore, the output of the motor 23 drives the drive wheel 24, which in turn drives the drive rod 25 to rotate the fan blade 26 at a constant speed. The rotation of the fan blade 26 generates wind power, which facilitates the cooling of the tea leaves.

[0032] Example 3

[0033] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: Preferably, the screening unit includes a screening screen plate 29 movably installed on the bottom of the cooling box 2. Limiting slide rods 210 are movably inserted into all four sides of the screening screen plate 29. A fixing block 211 is fixedly installed on the bottom end of the limiting slide rod 210. The fixing block 211 is fixedly installed on the inner wall of the bottom of the cooling box 2. A return spring is movably sleeved on the outer surface of the limiting slide rod 210 below the screening screen plate 29 and above the fixing block 211. 212. An inclined plate 213 is provided at the bottom of the interior of the cooling box 2. The other end of the inclined plate 213 extends to the bottom of the interior of the dust collection trough 4. A transmission belt 214 is movably sleeved on the outer surface of the drive wheel 24. A driven wheel 215 is movably sleeved inside the other end of the transmission belt 214. A pressing rod 216 is fixedly sleeved at the front end of the driven wheel 215. A contact plate 217 is provided below the pressing rod 216. The other end of the contact plate 217 passes through the left through hole of the cooling box 2 and is fixedly installed at the rear end of the screening screen plate 29.

[0034] Furthermore, when the tea leaves fall onto the top of the screening mesh plate 29, the mesh plate performs screening processing on the tea leaves, allowing impurities and broken leaves to be separated.

[0035] The working principle of the cooling air separation device used in tea production will be explained in detail below.

[0036] like Figure 1-5As shown, during use, the tea leaves to be cooled are guided into the feed hopper 27. The feed hopper 27 facilitates the slow downward movement of the tea leaves. The rotation of the drive roller 28 prevents the tea leaves from clogging the output end. As the tea leaves gradually descend, the output end of the motor 23 drives the drive wheel 24, which in turn drives the drive rod 25 to rotate the fan blades 26 at a constant speed. The rotation of the fan blades 26 generates airflow, facilitating the cooling of the tea leaves. When the tea leaves fall onto the top of the screening screen 29, the screen sieves the tea leaves, separating impurities and broken leaves. As the driving wheel 24 rotates, it drives the transmission belt 214 to cause the driven wheel 215 to rotate as well. When the driven wheel 215 rotates, it drives the pressing rod 216 to rotate and press against the top of the contact plate 217. The contact plate 217 is subjected to the pressing force, which causes the screening screen plate 29 to move downward and slide on the outer surface of the limiting slide rod 210, and presses the return spring 212. When the pressing rod 216 rotates away, the contact plate 217 loses the pressing force and rebounds to its original position under the elastic counter-propulsion force of the return spring 212. Thus, the screening screen plate 29 realizes up and down reciprocating motion, which further promotes the screening rate.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
