Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0036] Research has found that when tea leaves are transported in the existing technology, small pieces of soil, gravel, stems and hair are easily transported and packaged together with the tea leaves, which reduces the quality of the tea leaves after production. To this end, Example 1 proposes a conveying device for tea production, as shown in Figures 1 to 8. The conveying device for tea production includes a conveyor 100, a top shell 101 is fixed on one side of the top surface of the conveyor 100, and two rotating rods 102 are arranged on the top of the top shell 101. The outer wall of the rotating rod 102 is fixed with a plurality of circumferentially distributed driving strips 103, and the opposite sides of the outer wall of the driving strip 103 are respectively fixed with three evenly distributed positioning columns 106, and the outer wall of the positioning column 106 is movably connected with a rotating sleeve 104. The rotating sleeve 104 A number of winding columns 105 distributed in a circle are fixed to the outer wall, and a number of the driving strips 103 on both sides are staggered. A screening plate 400 is provided near the bottom of the top shell 101, and a connecting pipe 404 is connected to the middle of one side of the bottom of the screening plate 400. The inner side walls of the top shell 101 are rotatably connected to the bottom of one side, and cams 700 are fixed on both sides of the outer wall of the rotating rod 701. The outer wall of the cam 700 is in contact with the bottom of the screening plate 400, and an air-drying component is provided in the middle of the top shell 101.

[0037] As a further solution of the present invention, the air-drying component includes a processing barrel 301, which is fixed to the middle of the inner wall of the top shell 101. The top surface of the processing barrel 301 is connected with a collection frame 300. The outer wall of the collection frame 300 is fixed to the inner wall of the top shell 101. The inner wall of the processing barrel 301 is provided with a number of exhaust holes 302 distributed in a circle. An air pump 304 is fixed to the top of one side of the outer wall of the top shell 101. The output end of the air pump 304 is connected to an air filter 303. The output end of the air filter 303 passes through the top shell 101 and is connected with the outer wall of the processing barrel 301.

[0038] Through the provided collection frame 300, the tea leaves processed by the driving bar 103 and the winding column 105 can be collected in a centralized manner by the collection frame 300, thereby facilitating the tea leaves to enter the processing barrel 301. Through the provided filter, the air drawn in by the vacuum pump 304 can be filtered and processed to prevent dust in the air from being adsorbed on the surface of the tea leaves. Through the provided vacuum pump 304, the moisture on the surface of the tea leaves can be blown dry.

[0039] As a further solution of the present invention, a retaining frame 401 is fixed to the edge of the top surface of the screening plate 400 , and a plurality of evenly distributed collision columns 402 are fixed to the top surface of the screening plate 400 .

[0040] By setting up the collision column 402, when the tea leaves are vibrated and screened on the screening plate 400, the falling speed of the broken soil, gravel and stems mixed in the tea leaves can be slowed down, so that the broken soil, gravel and stems can collide with the collision column 402 and then pass through the screening plate 400.

[0041] As a further solution of the present invention, two symmetrically distributed inclined blocks 403 are fixed to one side of the top surface of the screening plate 400.

[0042] By providing the inclined block 403 , the screened tea leaves can conveniently enter the connecting pipe 404 and then enter the conveyor belt of the conveyor 100 .

[0043] As a further solution of the present invention, an inclined plate 600 is fixed to the bottom of the inner wall of the top shell 101 , the connecting pipe 404 movably passes through the inclined plate 600 , and a triangular block 601 is fixed to the top surface of the inclined plate 600 .

[0044] By setting the inclined plate 600, the broken soil, gravel and stems that fall onto the inclined plate 600 after screening can slide down along the inclined plate 600, making it easier to take out the broken soil, gravel and stems later. By setting the triangular block 601, the broken soil, gravel and stems will not be processed at the outer wall position of the connecting pipe 404, so that the broken soil, gravel and stems on the inclined plate 600 can all reach the bottom position, avoiding the connecting pipe 404 from blocking the broken soil, gravel and stems from sliding.

[0045] As a further solution of the present invention, two positioning grooves 501 are respectively provided on opposite sides of the outer wall of the screening plate 400 and the baffle frame 401, and two positioning bars 500 matching the positioning grooves 501 are respectively fixed on opposite sides of the inner wall of the top shell 101.

[0046] By providing the positioning grooves 501 and the positioning bars 500 , the position of the screening plate 400 can be movably limited in the vertical direction, thereby facilitating the vibration of the screening plate 400 .

[0047] As a further solution of the present invention, two discharge ports 800 are opened at the bottom of one side of the outer wall of the top shell 101, and the discharge ports 800 cooperate with the inclined plate 600. Two symmetrically distributed guide rails 801 are fixed on both sides of the bottom of one side of the outer wall of the top shell 101, and a baffle 802 is movably engaged between the two guide rails 801.

[0048] The discharging port 800 is provided so that the crushed soil, gravel and stems accumulated on the inclined plate 600 can be discharged from the discharging port 800 to an external collecting device, and the guide rail 801 is provided so that the position of the baffle 802 can be limited.

[0049] As a further solution of the present invention, rotating shafts 200 are fixed at both ends of the rotating rod 102, and gears 201 are fixed to the outer side walls of the two rotating shafts 200 on one side, and the two gears 201 are meshed.

[0050] The gear 201 is provided so that the two rotating rods 102 can rotate simultaneously, thereby causing the winding column 105 to wind and collect the filamentous impurities such as hair in the tea leaves.

[0051] As a further solution of the present invention, a second pulley 702 is fixed to the outer wall of the rotating shaft 200 on one side, a third pulley 704 is fixed to the outer wall of the rotating rod 701 on one side, and a second belt 703 is movably connected between the second pulley 702 and the third pulley 704.

[0052] By providing the second pulley 702 , the third pulley 704 and the second belt 703 , when the motor 204 rotates, it can not only drive the rotating rod 102 to rotate, but also drive the rotating rod 701 to rotate.

[0053] As a further solution of the present invention, a mounting plate 205 is fixed near the middle position on the other side of the outer wall of the top shell 101, a motor 204 is fixed on the top surface of the mounting plate 205, and a first pulley 202 is fixed on the output end of the motor 204 and the outer wall of the rotating shaft 200 on the other side, respectively, and a first belt 203 is movably connected between the two first pulleys 202.

[0054] The rotating rod 102 can rotate by means of the motor 204 , the first pulley 202 and the first belt 203 .

[0055] In summary, when processing tea leaves, first start the motor 204. The motor 204 rotates and drives the rotating rod 102 to rotate through the transmission of the first pulley 202 and the first belt 203. The two rotating rods 102 are finally driven to rotate through the transmission of the gear 201. At the same time, the second pulley 702, the third pulley 704 and the second belt 703 drive the rotating rod 701 to rotate. The rotation of the rotating rod 701 drives the cam 700 to rotate. The rotation of the cam 700 causes the screening plate 400 to vibrate back and forth, and the air filter 303 and the vacuum pump 304 are started. The vacuum pump 304 draws air into the air filter 303. The dust in the air is filtered and processed by the air filter 303, and then enters the processing barrel 301 and is discharged from the exhaust hole 302. The conveyor 100 is started, and then the tea leaves are poured into the top shell 10 1, when the tea leaves pass through the two rotating rods 102, the winding column 105 winds the hair and other filamentous impurities in the tea leaves on the winding column 105, and the tea leaves are driven downward by the driving bar 103, and then are collected by the collecting frame 300 and finally enter the processing barrel 301. The air in the processing barrel 301 blows the tea leaves, making the tea leaves air-dried, and then the tea leaves fall onto the screening plate 400. The screening plate 400 vibrates and screens the broken soil, gravel and stems in the tea leaves, so that the broken soil, gravel and stems pass through the screening plate 400 and fall onto the inclined plate 600. When the tea leaves slide down due to the vibration, the broken soil, gravel and stems collide with the collision column 402, so that the broken soil, gravel and stems fall slowly, and the tea leaves finally enter the connecting pipe 404, and fall onto the conveyor belt of the conveyor 100 through the connecting pipe 404, and are transported to the corresponding position by the conveyor belt.

[0056] The conveyor 100, the motor 204 and the air filter 303 can all be purchased on the market. They are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0057] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
