Description

Technical Field

[0001] This utility model relates to the field of tea cleaning technology, and in particular to a high-efficiency cleaning device for tea processing. Background Technology

[0002] Tea is a widely consumed beverage worldwide, boasting a rich cultural history and diverse varieties. Cleaning is a crucial step in tea processing. After picking, tea leaves may be covered with dirt, impurities, pests, or other contaminants. If these impurities are not effectively removed, they will affect the quality and taste of the tea. Therefore, using efficient cleaning equipment can help processors clean tea leaves more thoroughly and quickly, improving processing efficiency while ensuring tea quality.

[0003] However, existing tea washing devices first place the tea leaves on a feeding device, transporting them in batches into the washing area. The tea leaves are then conveyed to a washing device above for rinsing and cleaning. Afterward, a transfer device transports the washed tea leaves to the drying chamber for drying. During this process, as the tea leaves are transported from the feeding device to the conveyor, some leaves may fall into the gap between the feeding and conveyor devices and end up at the bottom of the washing area. If these leaves are not removed promptly, they may cause blockages at the washing area outlet or rot and breed bacteria due to prolonged accumulation, hindering subsequent tea washing. Removing these leaves requires disassembling the conveyor, which is time-consuming and labor-intensive, reducing efficiency and the device's practicality. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a high-efficiency cleaning device for tea processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency cleaning device for tea processing, comprising a base, the base being divided into a feeding area and a rinsing area by a rubber baffle, the feeding area being provided with an inclined feeding structure for uniform feeding of tea leaves, the rinsing area being provided with a conveying structure for conveying and cleaning tea leaves inside, the rinsing area being provided with a cleaning structure located above the conveying structure outside the rinsing area, the cleaning structure rinsing the tea leaves transported on the conveying structure, and the bottom of the base being provided with a collecting structure for collecting tea leaves that fall to the bottom of the rinsing area from the joint between the feeding structure and the conveying structure.

[0006] Preferably, the feeding area is provided above the lower rising part of the feeding structure, and a feeding guide plate is provided. The tea leaves are poured along the feeding guide plate and slide onto the feeding structure. The feeding area is provided at the end of the feeding structure, and a collection trough is provided to collect the tea leaves that fall from the gap between the feeding guide plate and the feeding structure.

[0007] Preferably, the feeding area is provided with a spreading plate at the top of the feeding structure to evenly spread the tea leaves that are piled up too high in the feeding structure.

[0008] Preferably, the cleaning structure includes mounting blocks installed on the two outer side walls of the rinsing area for mounting connecting frames, and a pipe assembly between the two connecting frames for rinsing the tea leaves on the conveying structure.

[0009] Preferably, the pipeline assembly includes multiple No. 1 pipelines and multiple No. 2 pipelines, which are connected by a three-way ball valve. Each No. 2 pipeline is equipped with multiple detachable bubble nozzles. The connecting frame on one side has an internal cavity that is connected to the left and right No. 1 pipelines and the external pipeline above. The external pipeline is connected to a water source, which enters the internal cavity of the connecting frame and flows into the No. 1 pipelines on the left and right sides. Through the three-way ball valve, the water source enters all the No. 2 pipelines and is sprayed out by the bubble nozzles to rinse the tea leaves.

[0010] Preferably, the end side walls of the rinsing zone are provided with limiting structures, and the rinsing zone limits the position of the transfer structure through the limiting structures. The transfer structure is used to transfer the tea leaves after they have been washed.

[0011] Preferably, the collection structure includes a collection component and an installation component, and the bottom of the rinsing area is provided with a groove for inserting the collection component and a strip groove for installing the installation component.

[0012] Preferably, the collecting component includes a collecting box with a connector for collecting fallen tea leaves. The collecting box is installed at the bottom of the rinsing area via the connector. A filter plate is provided on the top of the collecting box. The height of the filter plate extending into the rinsing area is exactly between the bottom of the conveying structure and the bottom wall of the rinsing area, which is used to block the fallen tea leaves on one side of the collecting box. The inner wall of the collecting box is provided with protrusions to increase friction with the tea leaves, making it difficult for the tea leaves that fall into the collecting box to flow. A shaft is provided inside the collecting box for winding up the cowhide cloth. One end of the cowhide cloth is provided with a limiting plate with a mounting hole. The outer surface of the cowhide cloth may also be provided with protrusions to increase friction with the tea leaves.

[0013] Preferably, the mounting component includes a guide rod installed at the bottom of the rinsing area and a limiting component that slides on the guide rod. The limiting component can limit the limiting plate at one end of the cowhide cloth.

[0015] In summary:

[0016] In this invention, by setting up a collection structure, as much tea leaves falling to the bottom of the rinsing zone as possible from the joint between the feeding structure and the conveying structure is collected. This avoids disassembling the conveying structure above the rinsing zone to collect the tea leaves at the bottom of the rinsing zone. It also prevents tea leaves from accumulating at the bottom of the rinsing zone, causing blockage of the water outlet or rotting and bacterial growth. This allows the water in the subsequent rinsing zone to be recycled, and provides a hygienic and safe effect for cleaning the next batch of tea leaves, thus improving the overall safety and practicality of the device.

[0024] Example 1: Refer to Figure 1-6 As shown, this utility model provides a technical solution: a high-efficiency cleaning device for tea processing, including a base 1. The base 1 is divided into a feeding area 11 and a rinsing area 12 by a rubber baffle 10. The feeding area 11 is provided with an inclined feeding structure 2 for uniform feeding of tea leaves. The rinsing area 12 is provided with a conveying structure 4 for conveying tea leaves for cleaning. The rinsing area 12 is provided with a cleaning structure 5 located above the conveying structure 4. The cleaning structure 5 rinses the tea leaves transported on the conveying structure 4. The bottom of the base 1 is provided with a collecting structure 6 for collecting tea leaves that fall to the bottom of the rinsing area 12 from the joint between the feeding structure 2 and the conveying structure 4.

[0025] Reference Figure 1 , Figure 2 and Figure 3 As shown, specifically, the feeding area 11 is located above the lower rising part of the feeding structure 2 and is provided with a feeding guide plate 112. The tea leaves are poured along the feeding guide plate 112 and slide onto the feeding structure 2. The feeding area 11 is provided with a collection trough 111 at the end of the feeding structure 2 to collect the tea leaves that fall into the gap between the feeding guide plate 112 and the feeding structure 2. The feeding structure 2 includes a conveyor belt, a motor and a motor-driven conveyor roller. The rotation of the conveyor roller drives the external conveyor belt to convey the tea leaves. A gearbox can also be provided at the feeding structure 2 to adjust the rotation speed of the motor, so as to adjust the feeding speed of the tea leaves by the feeding structure 2.

[0026] The effect and principle achieved by the above structure: When the tea leaves to be cleaned are poured into the feeding structure 2, the feeding guide plate 112 provides a certain guiding effect. At this time, some tea leaves that slide from the gap between the feeding guide plate 112 and the feeding structure 2 are collected by the collection tank 111, which avoids the tea leaves falling to the ground and causing waste. The feeding structure 2 transports the tea leaves in batches.

[0027] Reference Figure 1 , Figure 2 and Figure 3 As shown in this embodiment: The feeding area 11 is located at the top of the feeding structure 2 and is provided with a spreading plate 3 for evenly spreading the tea leaves that are piled too high on the feeding structure 2. The two side walls of the feeding area 11 are rotatably connected to a rotating shaft 31, which is fixedly connected to the spreading plate 3. A limiting component 32 is provided on one side of the rotating shaft 31 to adjust and limit the angle between the spreading plate 3 and the feeding structure 2, so as to evenly spread tea leaves of different thicknesses on the feeding structure 2. The limiting component 32 includes a circular plate installed at one end of the rotating shaft 31, a limiting hole on the outer wall of the circular plate and a matching pin.

[0028] Reference Figure 1 , Figure 2 and Figure 3As shown, specifically, the conveying structure 4 includes a motor, a motor-driven conveyor roller, a metal conveyor belt connected to the conveyor roller, and guide wheels for limiting the wrap angle between the metal conveyor belt and the conveyor roller. A gearbox for adjusting the motor's rotation speed can also be installed at the conveying structure 4 to regulate the conveying speed of the tea leaves in the washing area. The tea leaves are conveyed on the conveying structure 4, while the washing structure 5 above rinses the tea leaves on the conveying structure 4, ensuring that the conveying structure 4 keeps the tea leaves moving forward.

[0029] Reference Figure 2 As shown, specifically, the cleaning structure 5 includes mounting blocks 51. Mounting blocks 51 are installed on both outer walls of the rinsing area 12 for mounting connecting frames 52. A pipe assembly is arranged between the two connecting frames 52. The pipe assembly includes multiple first pipes 53 and multiple second pipes 55. The first pipes 53 and second pipes 55 are connected by a three-way ball valve 54. Each second pipe 55 is equipped with multiple detachable bubble nozzles 56. One side of the connecting frame 52 has an internal cavity that connects to the left and right first pipes 53 and the external pipe 57 above. The external pipe 57 is connected to a water source, which enters the internal cavity of the connecting frame 52 and flows into the first pipes 53 on the left and right sides. Water enters all the No. 2 pipes 55 through the three-way ball valve 54 and is sprayed out through the bubble nozzle 56 to rinse the tea leaves. An adjustment component 58 is set at the bottom of one of the mounting blocks 51 of the connecting frame 52 to drive the connecting frame 52 to raise and lower the entire pipe assembly. The raising and lowering of the pipe assembly can facilitate the maintenance of the conveying structure and can also adjust the intensity of rinsing the tea leaves to avoid damage to the tea leaves caused by water with too much impact force, which would affect the taste of the tea leaves. The adjustment component 58 includes a motor, a threaded rod, and a limiting bar rod that passes through the mounting block 51 and is set on the connecting frame 52. The motor drives the threaded rod to rotate, and the connecting frame 52 moves along the outer surface of the threaded rod due to the limitation of the limiting bar rod.

[0030] Reference Figure 2 As shown, specifically, the rubber baffle 10 is installed below the feeding structure 2. The top of the rubber baffle 10 is set in an arc shape and has strong elasticity. If the tea leaves on the feeding structure 2 fall to the arc-shaped position above the rubber baffle 10, there is a certain probability that they will be affected by the elastic force of the arc-shaped area of ​​the rubber baffle 10 and bounce back to the conveying structure 4. At the same time, the rubber baffle 10 in the arc-shaped area can deform, making it convenient to put the water pipe and water pump into the rinsing area and extract the water.

[0031] Reference Figure 5 and Figure 6As shown, specifically, the collecting structure 6 includes a collecting component and an installation component. The bottom of the rinsing zone 12 has a groove for inserting the collecting component and a strip groove for installing the installation component. The collecting component includes a collecting box 61 with a connector 611 for collecting fallen tea leaves. The collecting box 61 is installed at the bottom of the rinsing zone 12 via the connector 611. A sealing ring can be provided at the connection between the collecting box 61 and the groove. A first filter plate 62 is provided on the top of the collecting box 61. The height of the first filter plate 62 extending into the rinsing zone 12 is exactly at the bottom of the conveying structure 4 and the rinsing zone. Between the bottom walls of washing area 12, a section is used to contain fallen tea leaves on one side of the collection box 61. The inner wall of the collection box 61 has protrusions 63 to increase friction with the tea leaves, making it difficult for fallen tea leaves to flow. Inside the collection box 61, a shaft 64 is installed to wind up a leather cloth 66. One end of the leather cloth 66 has a limiting plate 67 with mounting holes. A torsion spring 65 is installed at the end of the shaft 64 that passes through the outside of the collection box 61. Pulling the leather cloth 66 causes the shaft 64 to rotate, torturing the torsion spring 65. When the leather cloth 66 is released... The rebound force of the torsion spring 65 causes the shaft 64 to rotate and reset, winding up the cowhide cloth 66. The outer surface of the cowhide cloth 66 may also be provided with protrusions 63 to increase friction with the tea leaves. The mounting components include a guide rod 610 installed at the bottom of the rinsing area 12 and a limiting member 68 sliding on the guide rod 610. The limiting member 68 can limit the limiting plate 67 at one end of the cowhide cloth 66. The limiting member 68 includes a slider mounted on the guide rod 610 and a bolt mounted on the slider for insertion into the mounting hole of the limiting plate 67. A sleeve can be fitted onto the guide rod 610. A first spring 69 is provided. The sliding limit member 68 on the guide rod 610 compresses the first spring 69, pulling the limit plate 67 on the kraft cloth 66 through the strip groove into the outside of the rinsing area 12. In this way, the entire kraft cloth 66 will cover the bottom wall of the rinsing area 12 on the other side of the first filter plate 62 and be placed below the limit member 68. When the limit member 68 is released, the rebound force of the first spring 69 causes the limit member 68 to move in the opposite direction along the guide rod 610 to reset and be fixed in the mounting hole on the limit plate 67. A sealing strip can be set at the contact point between the limit plate 67 and the strip groove.

[0032] The effects and principles achieved by the above components are as follows: When the water inside the rinsing zone 12 is drained by an external water pump, the tea leaves that were originally floating in the water at the bottom of the rinsing zone 12 will fall as much as possible onto the kraft cloth 66. At this time, the collection box 61 is removed, allowing the filter plate 62 to slowly leak out of its filter holes. The residual water at the bottom of the rinsing zone will then carry the tea leaves towards the collection box 61 and allow as much as possible to enter the collection box 61. Simultaneously, the limiting member 68 is opened to limit the limiting plate 67, allowing the limiting plate 67 to pass through the strip groove and enter the rinsing zone. Inside the washing area 12, the limiting plate 67 is released. Under the rebound force of the torsion spring 65, the shaft 64 quickly returns to its original position and rotates, causing the cowhide cloth 66 to quickly rewind. When the cowhide cloth 66 retracts, it will bring as much tea as possible scattered on the cowhide cloth 66 into the collection box 61. At this time, the amount of tea that has fallen into the washing area 12 from the gap between the feeding structure 2 and the conveying structure 4 is already small, and it has been collected by the above operation. At this time, any remaining tea can be completely removed by simply rinsing with water.

[0033] Reference Figure 1 , Figure 2 and Figure 5 As shown, specifically, a control panel 9 is installed on the base 1. The control panel 9 controls the operation of the internal electrical components of the feeding structure 2, the conveying structure 4, and the adjustment component 58 through wiring and electrical connections.

[0034] Reference Figure 2 and Figure 4 As shown, specifically, the end side walls of the rinsing area 12 are provided with limiting structures 8 for limiting the transfer structure 7 of the tea leaves after washing. The transfer structure 7 includes a transfer cart 71, which includes a handle and movable wheels. The side wall of the transfer cart 71 is provided with limiting grooves 74 for limiting and guiding with the machine base 1. Limiting rods 73 are provided on both sides of the transfer cart 71. A second filter plate 72 for receiving the washed tea leaves is slidably connected inside the transfer cart 71. The washed tea leaves are drained on the second filter plate 72. At this time, in order to prevent the tea leaves from accumulating on the second filter plate 72, the tea leaves can be spread out manually or with the help of tools such as a rake. The limiting structure 8 includes a component installed on the side wall of the machine base 1 for insertion into the limiting groove 74. The limiting block 81 of the part is connected to the transfer car 71 through the limiting groove 74 to limit the position. The limiting structure 8 also includes a buckle set on the side walls of both sides of the base 1 for limiting the limiting rod 73. The buckle includes a vertical rod 84 installed on the side wall of the base 1 and a limiting hole plate 82 that slides on the vertical rod 84. A second spring 83 is sleeved between the limiting hole plate 82 and the vertical rod 84. When the limiting hole plate 82 is pressed, it slides on the vertical rod 84 and squeezes the second spring 83. At this time, the transfer car 71 is connected to the limiting block 81 through the limiting groove 74. When the limiting hole plate 82 is released, the rebound force of the second spring 83 causes the limiting hole plate 82 to slide along the vertical rod 84 and lock onto the outer surface of the limiting rod 73 for limiting.

[0035] The electrical components mentioned above are all available on the market, so the wiring and connection are not discussed in detail since they are not related to innovation. Some electrical components can also be obtained through private customization, so they will not be discussed in detail (for example, the control panel 9 controls the feeding structure 2, the conveying structure 4, and the adjustment component 58, etc.).

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
