Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and more specifically, to a tea processing screening device. Background Technology

[0002] Tea leaves vary in size after picking, and different sizes of tea leaves have different requirements for "force, heat, and time" during processing. If tea leaves are mixed for processing, some tea leaves may be damaged, affecting the aroma and color of the entire batch of tea. Therefore, before processing, it is necessary to use a screening device to grade and screen the tea leaves according to their size.

[0003] Currently, the commonly used screening device is a drum-type structure. The drum rotates, causing the tea leaves to be continuously scattered and screened using the sieve holes on the drum. However, during the process of the drum scattering the tea leaves, the tea leaves are only scattered on one side of the drum, and the scattered tea leaves pile up together, resulting in poor screening effect of the sieve holes. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tea processing screening device to solve the problem that in the existing screening device, during the process of tea scattering in the drum, the tea is only scattered on one side of the drum and the scattered tea leaves pile up together, resulting in poor tea sieving effect of the sieve holes.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a tea processing and screening device, including a base, a support frame fixedly installed on the base, a roller rotatably connected to the support frame, a rotary drive assembly for driving the roller to rotate on the support frame, an inclined dispersing plate provided on the inner side of the roller, a sliding sleeve fixedly installed on the side of the support frame, a sliding rod slidably inserted into the sliding sleeve, the dispersing plate fixedly connected to the middle of the sliding rod, and a reciprocating dispersing assembly capable of driving the dispersing plate to move back and forth on the base.

[0006] Preferably, the reciprocating dispersion component includes a second support frame, which is fixedly mounted on a base. Both ends of the slide rod are fixedly connected to vertical grooves. A multi-shaped rod is rotatably connected to the top of the second support frame. The middle part of the multi-shaped rod is slidably mounted in the vertical groove. A second motor is fixedly mounted on the second support frame, and the output end of the second motor is connected to one end of the multi-shaped rod.

[0007] Preferably, the rotary drive assembly includes two drive wheels, both of which are rotatably connected to a support frame and are frictionally connected to the outer side of the roller end. Synchronous pulleys are fixedly installed on the shafts of the two drive wheels, and a belt is fitted between the two synchronous pulleys. A motor is fixedly installed on the support frame, and the output end of the motor is connected to the shaft end of the drive wheel.

[0008] Preferably, the roller has a frustum-shaped structure, and the surface of the roller is uniformly distributed with a first sieve hole and a second sieve hole along the axial direction. The diameter of the first sieve hole is smaller than that of the second sieve hole, and the inner side of the roller is welded with ribs.

[0009] Preferably, the base is provided with casters at all four corners of the bottom, and a feeding hopper is fixedly installed on one side of the support frame and a discharging hopper is fixedly installed on the other side.

[0010] Preferably, a screening slide plate fixed to a support frame is provided below the roller, and a partition plate located between the first screen hole and the second screen hole is welded to the middle of the screening slide plate.

[0011] Preferably, the top of the support frame is fixed with a splash guard that covers the roller.

[0012] Preferably, a pipe is welded to the top of the splash guard, and a fan is installed on the inner wall of the pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses ribs to toss tea leaves into the air. As the tea leaves fall, some of them land on a dispersing plate. At this point, the reciprocating dispersing component is activated, causing the inclined surface of the dispersing plate to quickly push some of the tea leaves back to the other side of the drum. During this pushing process, the tea leaves are evenly scattered on the other side of the drum, while the remaining tea leaves fall directly back to the original tossing position. This process is repeated to screen the tea leaves, expanding the screening area of ​​the drum and thus improving the screening efficiency.

[0015] This invention, through the setting of a screening slide and a separator plate, allows the screened tea leaves to slide down the screening slide and be separated into different sizes by the separator plate, thus automatically separating the screened tea leaves.

[0016] In the screening process, this invention activates a blower to generate an inward blowing force on the drum screen holes, clearing away tea leaves stuck in the screen holes and preventing them from affecting the tea screening effect. Attached Figure Description

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 5 This utility model provides a tea processing and screening device, including a base 1, a support frame 2 fixedly installed on the base 1, a roller 3 rotatably connected to the support frame 2, a rotary drive assembly 8 for driving the roller 3 to rotate on the support frame 2, an inclined dispersing plate 4 provided on the inner side of the roller 3, a sliding sleeve 5 fixedly installed on the side of the support frame 2, a sliding rod 6 slidably inserted into the sliding sleeve 5, the dispersing plate 4 fixedly connected to the middle of the sliding rod 6, and a reciprocating dispersing assembly 7 capable of driving the dispersing plate 4 to reciprocate on the base 1.

[0026] Preferably, the reciprocating dispersion component 7 includes a second support frame 71, which is fixedly installed on the base 1. Both ends of the slide rod 6 are fixedly connected to vertical groove bodies 72. The top of the second support frame 71 is rotatably connected to a multi-shaped rod 73. The middle part of the multi-shaped rod 73 is slidably installed in the vertical groove body 72. A second motor 74 is fixedly installed on the second support frame 71, and the output end of the second motor 74 is connected to one end of the multi-shaped rod 73.

[0027] Among them, the rotating rod 73 is driven by the motor 74. The part of the rotating rod 73 that is off-center can be matched with the vertical groove 72, which drives the dispersion plate 4 and the slide rod 6 to move back and forth horizontally along the sliding sleeve 5.

[0028] Preferably, the rotary drive assembly 8 includes two drive wheels 81, both of which are rotatably connected to the support frame 2, and the drive wheels 81 are frictionally connected to the outer side of the end of the roller 3. Synchronous pulleys 82 are fixedly installed on the shafts of the two drive wheels 81, and a belt 83 is fitted between the two synchronous pulleys 82. A motor 84 is fixedly installed on the support frame 2, and the output end of the motor 84 is connected to the shaft end of the drive wheel 81.

[0029] In this system, through the synchronous driving action of the synchronous pulley 82 and the belt 83, the motor 84 drives one of the drive wheels 81 to rotate, and the other drive wheel 81 rotates synchronously in the same direction. The friction between the drive wheel 81 and the drum 3 drives the drum 3 to rotate, thus screening the tea leaves.

[0030] Preferably, the roller 3 has a frustum-shaped structure, and the surface of the roller 3 is uniformly distributed with a first sieve hole 31 and a second sieve hole 32 along the axial direction. The diameter of the first sieve hole 31 is smaller than the diameter of the second sieve hole 32. Ribs 33 are welded to the inner side of the roller 3.

[0031] During the rotation of the drum 3, the tea leaves will gradually move from the side with a smaller diameter to the side with a larger diameter, so that the tea leaves pass through the first sieve hole 31 and the second sieve hole 32 in sequence, and the tea leaves are screened from small to large. The ribs 33 can rotate synchronously with the drum 3 to turn and toss the tea leaves, which helps to improve the screening efficiency.

[0032] Preferably, the base 1 is equipped with casters 9 at all four corners of the bottom. By feeding the tea into the casters 9, the tea leaves can automatically slide into the feed end of the roller 3 for screening and processing. A feeding hopper 10 is fixedly installed on one side of the support frame 2, and a discharge hopper 11 is fixedly installed on the other side. Tea leaves larger than the diameter of the second screen hole 32 can slide out and be discharged along the discharge hopper 11.

[0033] Specifically, in existing screening devices, the tea leaves are turned and tossed at approximately the following positions: Figure 4 In area A, the contact area between the tea leaves and the drum 3 is relatively small, which may result in some tea leaves not being accurately screened, leading to low screening efficiency. However, the tea processing and screening device of this application, during use, involves feeding tea leaves into the drum 3 through the feeding hopper 10, activating the rotary drive assembly 8 to rotate the drum 3 and the ribs 33, causing the tea leaves to be tumbled and screened through the first screen hole 31 and the second screen hole 32. Simultaneously, through a program set in the controller, the ribs 33 throw the tea leaves up. As the tea leaves fall, some will land on the dispersing plate 4. At this point, the reciprocating dispersing assembly 7 is activated, causing the inclined surface of the dispersing plate 4 to push some of the tea leaves to the other side of the drum 3 (approximately...). Figure 4 The tea leaves are quickly pushed back once in the middle B area. During the pushing process, the tea leaves are evenly scattered on the other side of the drum 3. The remaining tea leaves fall directly to the original turning position. This process is repeated to screen the tea leaves, which expands the screening area of ​​the drum 3 and thus improves the screening efficiency of the tea leaves.

[0034] Furthermore, a screening slide plate 12 fixed on the support frame 2 is provided below the roller 3, and a partition plate 13 located between the first screen hole 31 and the second screen hole 32 is welded to the middle of the screening slide plate 12.

[0035] The screened tea leaves can slide down the screening slide plate 12 and be separated into different sizes by the separator plate 13.

[0036] Furthermore, the top of the support frame 2 is fixed with a splash guard 14 that covers the roller 3, which can intercept the tea leaves that fly directly out of the sieve holes during the turning process, so that the tea leaves fall evenly onto the sieve slide plate 12 for easy collection and processing.

[0037] Furthermore, a pipe 15 is welded to the top of the splash guard 14, and a fan 16 is installed on the inner wall of the pipe 15.

[0038] During the screening process, the blower 16 is activated to generate an inward blowing force on the screen holes of the drum 3, which clears the tea leaves stuck in the screen holes and avoids affecting the tea screening effect.
