Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically to a high-efficiency and stable tea conveying device. Background Technology

[0002] In the traditional tea processing industry, sorting and conveying equipment is a key component. Existing technologies typically include various mechanical devices such as conveyor belts, screening machines, and other mechanical structures for sorting tea leaves of different sizes and qualities. The main function of these devices is to ensure that tea leaves are effectively classified and transferred during processing, thereby improving the efficiency of the entire production process.

[0003] In the existing technology, the conveying device screens the tea leaves by vibration when conveying them. The conveying device is generally set at an angle. When the device vibrates, the tea leaves can easily slide directly downwards. At this time, some tea leaves may slide directly downwards without being screened, which can easily affect the screening effect of the tea leaves.

[0004] This utility model proposes an efficient and stable tea conveying device to solve the problem that when conveying tea, the tea is sieved by vibration. The conveying device is generally set at an incline. When the device vibrates, the tea leaves can easily slide directly downwards. At this time, some tea leaves may slide downwards without being sieved, which can easily affect the sieving effect of the tea leaves. Utility Model Content

When the device vibrates, the tea leaves can easily slide directly downwards. At this time, some tea leaves may slide directly downwards without being sieved, which can easily affect the sieving effect of the tea leaves.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0007] A high-efficiency and stable tea conveying device includes a left support and a right support. A multi-stage screen is movably arranged between the left and right supports. Limiting rods are fixedly inserted into both the front and rear sides of the multi-stage screen. The two limiting rods on the left side are movably inserted into the left support, and the two limiting rods on the right side are movably inserted into the right support. Rotating rods are rotatably arranged in both the left and right supports. The ends of the two rotating rods are connected by a transmission belt.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0024] Example 1: This example provides a highly efficient and stable tea conveying device, such as... Figure 1 As shown, this invention addresses the problem of tea leaves being sieved through vibration during conveying, especially since the conveying device is typically tilted. When the device vibrates, the tea leaves tend to slide directly downwards, potentially affecting the sieving effect. The invention includes a left support 1 and a right support 2. First, the tea leaves are poured into the right side of the multi-stage screen 3. Then, a motor 9 and a transmission belt 6 drive two rotating rods 5 to rotate synchronously. These rods then rotate the first control disc 7 and the second control disc 8, causing the multi-stage screen 3 to vibrate up and down. During this process, the multi-stage screen 3 sieves the tea leaves. After multiple vibrations, the screen 3 tilts, causing the sieved tea leaves to slide downwards for further sieving. This multiple vibrations followed by tilting and feeding reduces the possibility of unscreened tea leaves being conveyed directly downwards with other tea leaves, thus improving the sieving effect.

[0025] A multi-stage screen 3 is movably installed between the left support 1 and the right support 2. Limiting rods 4 are fixedly inserted into both the front and rear sides of the multi-stage screen 3. The two limiting rods 4 on the left side are movably inserted into the left support 1, and the two limiting rods 4 on the right side are movably inserted into the right support 2. Rotating rods 5 are rotatably installed in both the left support 1 and the right support 2. The ends of the two rotating rods 5 are connected by a transmission belt 6. Two first control discs 7 are symmetrically sleeved on the left rotating rod 5, and two second control discs 8 are symmetrically sleeved on the right rotating rod 5. The bottom surface of the multi-stage screen 3 slides in contact with the outer surfaces of the first control discs 7 and the second control discs 8. A motor 9 is fixedly installed on the left support 1, and the rotating shaft of the motor 9 is fixedly connected to one end of the left rotating rod 5.

[0026] Combination Figure 1 , Figure 2 In this embodiment of the present invention, a limiting groove 11 is provided on the left support 1, the left limiting rod 4 is inserted into the limiting groove 11 and a bushing 12 is fixedly sleeved thereon, and a plurality of springs 13 are fixedly provided on the outer wall of the bushing 12. The upper ends of the plurality of springs 13 are fixedly connected to the inner top wall of the limiting groove 11. The bushing 12 facilitates the limiting rod 4 to be limited inside the limiting groove 11, thereby causing the limiting rod 4 to only drive the left end of the multi-stage screen 3 to move up and down. The bushing 12 also allows the right end of the multi-stage screen 3 to deflect up and down. The springs 13 facilitate the pushing of the bushing 12 and the limiting rod 4 downward, thereby causing the abutment rod 32 at the bottom of the multi-stage screen 3 to always abut against the outer wall of the first control disk 7 and the second control disk 8.

[0027] Combination Figure 1 In this embodiment of the utility model, a movable groove 21 is provided on the right support 2. The movable groove 21 is arc-shaped. The right limiting rod 4 is movably inserted into the movable groove 21 and slides in cooperation with the inner wall of the movable groove 21. The movable groove 21 facilitates the limiting of the right limiting rod 4, thereby increasing the stability of the multi-stage screen 3 when it deflects.

[0028] Example 2: Reference Figure 2 , Figure 3 The multi-stage screen 3 has three sets of screening holes 31, and the inner diameter of the three sets of screening holes 31 decreases from left to right. The bottom surface of the multi-stage screen 3 is fixedly provided with abutment rods 32 corresponding to the first control disk 7 and the second control disk 8. The lower end of the abutment rods 32 slides in cooperation with the outer surface of the first control disk 7 and the second control disk 8. The three sets of screening holes 31 facilitate the screening of tea leaves of different specifications, so as to facilitate the classification of tea leaves. The abutment rods 32 cooperate with the first control disk 7 and the second control disk 8 to facilitate the control of the vibration and tilt of the multi-stage screen 3, thereby realizing the conveying and screening of tea leaves.

[0029] The multi-stage screen 3 has three collection boxes 10 at its bottom. The positions of the three collection boxes 10 correspond to the positions of the three sets of sieving holes 31. The collection boxes 10 are used to collect the sieving tea leaves. The three collection boxes 10 facilitate the classification and collection of the tea leaves sieving through the three sets of sieving holes 31.

[0030] Two baffles 33 are fixedly installed on the top surface of the multi-stage screen 3. The two baffles 33 are used to separate the three sets of screening holes 31 and to block the tea leaves. The baffles 33 can block the tea leaves to reduce the possibility that some tea leaves will move directly downwards without being screened.

[0031] Example 3: Reference Figure 2 , Figure 3 The outer wall of the first control disk 7 is provided with several first grooves 71. The lower end of the left abutment rod 32 slides in cooperation with the inner wall of the first groove 71. When the rotating rod 5 drives the first control disk 7 to rotate, the abutment rod 32 intermittently inserts into the first groove 71, thereby causing the multi-stage screen 3 to shake up and down, so as to facilitate the sieving of tea leaves.

[0032] The outer wall of the second control disk 8 has several second grooves 81, and a protrusion 82 is fixedly installed on the outer wall of the second control disk 8. The lower end of the right-side contact rod 32 slides in cooperation with the inner wall of the second groove 81 and the outer surface of the protrusion 82. When the rotating rod 5 drives the second control disk 8 to rotate, the contact rod 32 intermittently inserts into the second groove 81, thereby causing the multi-stage screen 3 to shake up and down. When the second control disk 8 rotates until the protrusion 82 coincides with the contact rod 32, the contact rod 32 is pushed and drives the right end of the multi-stage screen 3 to move upward. At this time, the left end of the multi-stage screen 3 moves downward, thereby causing the multi-stage screen 3 to be in an inclined state, thus realizing the conveying of tea leaves.

[0033] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
