[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 shown, a winnowing machine for tea processing includes a housing 1, a feeding hopper 2 is fixedly connected to the top of the housing 1, a collection structure 3 is fixedly installed on the left part of the housing 1, and a feeding structure 4 is fixedly installed on the front part of the housing 1.

[0025] By setting the collection structure 3 and starting the air pump 34, a certain air flow is formed inside the box, and then the tea leaves sliding down from the second inclined plate 46 are winnowed. At this time, the relatively complete and heavier tea leaves directly fall into the collection box 32. After that, the collection box 32 can be taken out by pulling out the cover plate 33, and the tea leaves collected inside can be further processed or stored. The smaller debris or dust passes through the first filter plate 35 under the action of the air flow and is then discharged from the inside of the housing 1 under the action of the second filter plate 37.

[0026] As Figure 2 and Figure 3 shown, the collection structure 3 includes a U-shaped frame 31. The collection box 32 is lapped inside the top of the U-shaped frame 31. The outer wall of the collection box 32 is inserted into the front part of the housing 1. The front end of the collection box 32 is fixedly connected with a cover plate 33. The rear part of the cover plate 33 is inserted into the lower part of the front part of the housing 1. An air pump 34 is fixedly installed on the right part of the U-shaped frame 31.

[0027] By setting the collection box 32 and starting the air pump 34, a certain air flow can be formed inside the box, and then the tea leaves sliding down from the second inclined plate 46 are winnowed. At this time, the relatively complete and heavier tea leaves directly fall into the collection box 32. After that, the collection box 32 can be taken out by pulling out the cover plate 33, and the tea leaves collected inside can be further processed or stored.

[0028] As Figure 3As shown, the right part of the top end of the U-shaped frame 31 is plugged with a first filter plate 35. The front end of the first filter plate 35 is fixedly connected with a magnetic plate 36. The rear end of the magnetic plate 36 is magnetically connected to the front end of the housing 1. The left end of the U-shaped frame 31 is fixedly connected with a second filter plate 37. The left end of the second filter plate 37 extends out of the housing 1 at a position slightly below the left end.

[0029] By setting the first filter plate 35 and the second filter plate 37, debris or dust with relatively small mass passes through the first filter plate 35 under the action of air flow and is then discharged from the inside of the housing 1 under the action of the second filter plate 37. The magnetic plate 36 can be used to replace the first filter plate 35, so as to perform air separation on different types of tea.

[0030] As Figure 4 and 5 As shown, a first transmission assembly 39 is fixedly installed at a position slightly to the left of the rear end of the housing 1. The first transmission assembly 39 includes a first protective shell, two transmission rollers and a toothed belt. The outer walls of the two transmission rollers are both meshed with the inner wall of the toothed belt. The two transmission rollers and the toothed belt are all located inside the first protective shell. The top of the rear end of the first protective shell is fixedly installed with a first motor 38. The output end of the first motor 38 is fixedly connected to the rear end of the upper transmission roller. The front ends of the two transmission rollers both extend into the housing 1. The front ends of the two transmission rollers are both fixedly connected with round rods 310. A number of protrusions 311 are fixedly connected to the outer walls of the two round rods 310. The two round rods 310 are respectively located at the left end of the first filter plate 35 and below the second filter plate 37.

[0031] By setting the protrusions 311, start the second motor 41 to drive the first transmission assembly 39 to work, thereby driving the two round rods 310 to rotate, so that the protrusions 311 on the two round rods 310 respectively strike the two filter plates, thereby preventing tea debris and the like from blocking the first filter plate 35 and the second filter plate 37.

[0032] As Figure 4As shown, the feeding structure 4 includes a second motor 41. At the top of the front end of the housing 1, a second transmission assembly 42 is fixedly installed. The second transmission assembly 42 includes a second protective housing, a first transmission belt, and two first transmission gears. The outer walls of the two first transmission gears are meshed with the inner wall of the first transmission belt. The first transmission belt and the two first transmission gears are both located inside the second protective housing. The left part of the front end of the second protective housing is fixedly installed with the rear part of the second motor 41. The output end of the second motor 41 is fixedly connected to the front end of the first transmission gear on the left. The rear ends of the two first transmission gears both extend into the interior of the housing 1. The rear ends of the two transmission gears are both fixedly connected with transmission rods 43. A conveyor belt 44 is meshed with the outer walls of the two transmission rods 43. The left part of the conveyor belt 44 is directly below the feed hopper 2. At the top of the left side inside the housing 1, a first inclined plate 45 is fixedly connected. The bottom end of the first inclined plate 45 is lapped with the left part of the top end of the conveyor belt 44. At a position above the middle on the right side inside the housing 1, a second inclined plate 46 is fixedly connected. The second inclined plate 46 is located below the right part of the conveyor belt 44.

[0033] By setting the conveyor belt 44 and using the rotation of the conveyor belt 44, the tea is sent to the second inclined plate 46, and then through the action of the second inclined plate 46, feeding is carried out, thereby realizing the uniform feeding of the tea, avoiding a large amount of tea being put into the interior of the housing 1 at one time, and thus affecting the air separation effect.

[0034] As Figure 4 and Figure 5 As shown, at a position to the right of the top of the rear end of the housing 1, a third transmission assembly 48 is fixedly installed. The third transmission assembly 48 includes a third protective housing, a second transmission belt, and two second transmission gears. The outer walls of the two second transmission gears are meshed with the inner wall of the second transmission belt. The second transmission belt and the two second transmission gears are both located inside the third protective housing. The front end of the second transmission gear located below is fixedly connected to the rear end of the transmission rod 43 on the right. The front end of the second transmission gear located above is fixedly connected with a brush roller 47. The front end of the brush roller 47 is rotatably connected to the top of the front end of the inner cavity of the housing 1. The brush roller 47 is located above the right part of the conveyor belt 44.

[0035] By setting the brush roller 47, while the transmission rod 43 on the right rotates, the third transmission assembly 48 works, thereby driving the brush roller 47 to rotate. The rotation of the brush roller 47 levels the tea, thereby making the feeding of the tea more uniform and dispersed, and further improving the air separation effect.

[0036] Working principle of the utility model: When in use, start the second motor 41, feed the tea leaves into the interior of the housing 1 through the feed hopper 2. Under the action of the second motor 41, the two transmission rods 43 drive the conveyor belt 44 to rotate, and then send the tea leaves to the second inclined plate 46. Then, under the action of the second inclined plate 46, feeding is carried out, thereby realizing uniform feeding of the tea leaves, avoiding a large amount of tea leaves being put into the interior of the housing 1 at one time, which may affect the air separation effect. While the right transmission rod 43 is rotating, the third transmission assembly 48 works, thereby driving the brush roller 47 to rotate. The rotation of the brush roller 47 equalizes the tea leaves, making the feeding of the tea leaves more uniform and dispersed, and further improving the air separation effect. Start the air pump 34, thereby forming a certain airflow inside the box body, and then carry out air separation on the tea leaves sliding down from the second inclined plate 46. At this time, the relatively complete and heavier tea leaves directly fall into the collection box 32. After that, the collection box 32 can be taken out by pulling out the cover plate 33, and the tea leaves collected inside can be further processed or stored. The smaller-quality debris or dust passes through the first filter plate 35 under the action of the airflow and is discharged from the interior of the housing 1 under the action of the second filter plate 37. During this process, start the second motor 41, thereby driving the first transmission assembly 39 to work, and then driving the two round rods 310 to rotate, causing the bumps 311 on the two round rods 310 to strike the two filter plates respectively, thereby preventing the tea leaf debris, etc. from blocking the first filter plate 35 and the second filter plate 37, which may directly affect the air separation effect.
