Description

Technical Field

[0001] This utility model relates to the technical field of tea processing equipment, specifically a tea impurity removal and separation device. Background Technology

[0002] Tea is a high-end food and beverage, and its quality directly affects its taste and nutrition. The presence of impurities can have a serious adverse effect on the quality of tea, such as tea seeds, stones, sand, and soil. Therefore, impurity removal and separation devices are needed to process tea for impurity removal, as follows.

[0003] A search revealed a patent with authorization announcement number CN220239209U, which discloses a tea-processing impurity removal device. The device includes a base with a filter screen inside. A placement box is located at the lower end of one side of the base, and a motor is mounted on one side of the placement box. The output end of the motor passes through the placement box and is connected to a rotating shaft. Cams are fixedly connected to the outer walls of both sides of the rotating shaft. A sliding plate is slidably connected inside the placement box, and knocking rods are located on both sides of the upper end of the sliding plate. Sliding grooves are formed on both sides of the base, and threaded rods are installed inside the sliding grooves. A sliding seat is threadedly connected to the outer wall of the threaded rod, and an electric telescopic rod is located at the upper end of the sliding seat. A connecting rod is fixedly connected to the upper end of the electric telescopic rod, and multiple toggle blocks are located at the lower end of the connecting rod. This invention can quickly filter impurities from tea leaves, allows for tea leaf movement to facilitate impurity removal, and collects and treats dust and gases generated during the impurity removal process.

[0004] However, the aforementioned patents still have the following areas for improvement:

[0005] After the tea leaves are cleaned, they still need to be discharged separately, and impurities need to be cleaned separately. This means that after a portion of the tea leaves are cleaned, the processing needs to be paused for discharge or cleaning, resulting in low processing efficiency. Although the method of using a prying block to move the tea leaves can prevent them from piling up tightly to some extent, there are gaps between adjacent prying blocks, resulting in poor uniformity of movement. This can lead to the tea leaves piling up tightly between adjacent prying blocks, which greatly reduces the cleaning effect. The structure needs to be improved, and the practicality needs to be enhanced. Utility Model Content

[0010] The aforementioned material feeding structure includes a mounting frame, a first motor, and a turntable. The material feeding structure is provided in two sets. The first motor is fixedly installed on the top of the mounting frame. The top of the turntable is connected to the output end of the first motor, and the turntable is located at the bottom of the mounting frame. Multiple material feeding strips are fixedly connected to the bottom of the turntable.

[0011] As described above, the mounting bracket is fixedly installed on the top of the screening frame, and the feeding strip is made of soft rubber material.

[0012] The aforementioned auxiliary vibration structure includes a mounting plate, a second motor, an eccentric wheel, a movable rod, and spring plates. The second motor is fixedly mounted on the top of the mounting plate. The eccentric wheel is connected to the output end of the second motor. Multiple balls are movably mounted on the outer circumference of the eccentric wheel. The movable rod movably passes through the mounting plate. A top plate is fixedly connected to the top of the movable rod. The top of the top plate contacts the balls on the outer circumference of the eccentric wheel. A bottom plate is fixedly connected to the bottom of the movable rod. Multiple spring plates are provided. The two ends of the multiple spring plates are fixedly connected to the mounting plate and the bottom plate, respectively. Two sets of connecting rods are fixedly connected to the bottom of the bottom plate.

[0013] As described above, the mounting plate is fixedly installed on the side of the impurity removal box away from the feed hopper, and the bottom ends of both sets of connecting rods are fixedly connected to the top of the screening frame.

[0014] The drying structure described above includes a hot air blower and an air supply pipe. The air outlet of the hot air blower is fixedly connected to one end of the air supply pipe, and a diffuser is fixedly connected to the other end of the air supply pipe.

[0016] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0017] I. This utility model, by incorporating an auxiliary vibration structure and a material feeding structure, allows for continuous feeding of tea leaves into the screening frame via the feed hopper during operation. This activates both the first and second motors. The second motor drives an eccentric wheel to rotate. As the eccentric wheel rotates, it engages with multiple ball bearings on its outer circumference to move the top plate up and down. A spring plate assists in the top plate's downward movement and subsequent upward return to its original position. During the top plate's up-and-down movement, a movable rod moves the bottom plate up and down, which, in conjunction with multiple sets of connecting rods, moves the screening frame up and down, assisting in the vibration of the screening frame and improving the tea leaf impurity removal effect. Furthermore, because the screening frame is inclined... Therefore, the screened tea leaves can be directly discharged through the opening side of the screening frame, while the screened impurities fall to the bottom of the impurity removal box and are discharged through the discharge chute. No manual discharge is required afterward, and the tea leaf impurity removal process can be carried out continuously without interrupting the processing, which greatly improves the overall tea leaf impurity removal efficiency. During this process, the operation of the first motor drives the turntable to rotate, which in turn drives multiple feeding strips to rotate, thereby evenly moving the tea leaves inside the screening frame that pass under the turntable, effectively preventing the tea leaves from piling up tightly and affecting the impurity removal effect.

[0018] Second, this utility model has a drying structure, which allows the tea leaves inside the sieving frame to be effectively dried by the operation of a hot air blower, in conjunction with the air supply pipe and the air diffuser, thus preventing the tea leaves from deteriorating and being damaged during subsequent storage due to excessive moisture.

[0019] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, this utility model provides a technical solution: a tea impurity removal and separation device, including an impurity removal box 1, with through grooves 2 on both sides of the impurity removal box 1, the two through grooves 2 having different heights, a feed hopper 3 fixedly installed on the side of the impurity removal box 1 with the higher through groove 2, and a discharge groove 4 opened at the bottom of the impurity removal box 1 with the higher through groove 2, the inner bottom surface of the impurity removal box 1 inclined towards the discharge groove 4, a screening frame 5 slidably connected inside the impurity removal box 1, the top and one side of the screening frame 5 being open, the two ends of the screening frame 5 extending through the two through grooves 2 to the outside of the impurity removal box 1 respectively, the screening frame 5 being inclined, a material feeding structure 6 fixedly installed on the top of the screening frame 5, an auxiliary vibration structure 7 fixedly installed on the side of the impurity removal box 1 away from the feed hopper 3 and connected to the screening frame 5, and a drying structure 8 fixedly installed on the top of the impurity removal box 1, the drying structure 8 extending into the interior of the impurity removal box 1.

[0028] The bottom of the sieving frame 5 has multiple through sieving holes, which are used to sieve impurities in the tea leaves.

[0029] The feeding structure 6 includes a mounting frame 601, a first motor 602, and a turntable 603. The feeding structure 6 has two sets. The first motor 602 is fixedly installed on the top of the mounting frame 601. The top of the turntable 603 is connected to the output end of the first motor 602, and the turntable 603 is located at the bottom of the mounting frame 601. Multiple feeding strips 604 are fixedly connected to the bottom of the turntable 603, so that the first motor 602 can drive the turntable 603 to rotate. The rotation of the turntable 603 can drive the multiple feeding strips 604 to rotate, thereby making the tea leaves inside the screening frame 5 passing under the turntable 603 more evenly fed, thus effectively preventing the tea leaves from piling up tightly and affecting the impurity removal effect.

[0030] The mounting bracket 601 is fixedly installed on the top of the screening frame 5. The feeding bar 604 is made of soft rubber material, which makes it less likely to damage the tea leaves.

[0031] The auxiliary vibration structure 7 includes a mounting plate 701, a second motor 702, an eccentric wheel 703, a movable rod 704, and spring plates 705. The second motor 702 is fixedly mounted on the top of the mounting plate 701. The eccentric wheel 703 is connected to the output end of the second motor 702. Multiple balls 706 are movably mounted on the outer circumference of the eccentric wheel 703. The movable rod 704 movably passes through the mounting plate 701. A top plate 707 is fixedly connected to the top of the movable rod 704. The top of the top plate 707 contacts the balls 706 on the outer circumference of the eccentric wheel 703. A base plate 708 is fixedly connected to the bottom of the movable rod 704. Multiple spring plates 705 are provided, and their two ends are fixedly connected to the mounting plate 701 and the base plate 708, respectively. Two sets of connecting rods 709 are fixedly connected to the bottom of the base plate 708, so that during operation, the second motor 702 can drive the vibration structure. When the eccentric wheel 703 rotates, it works with multiple ball bearings 706 on its outer circumference to move the top plate 707 up and down. The spring plate 705 assists the top plate 707 in rebounding and resetting after it moves down. When the top plate 707 moves up and down, it works with the movable rod 704 to move the bottom plate 708 up and down, which in turn works with multiple sets of connecting rods 709 to move the screening frame 5 up and down, assisting the screening frame 5 in vibrating and improving the tea impurity removal effect. Since the screening frame 5 is inclined, the screened tea can be discharged directly through the opening side of the screening frame 5. The screened impurities fall to the bottom of the impurity removal box 1 and are discharged through the discharge chute 4. No manual discharge is required afterward, and the tea impurity removal process can be carried out continuously without interrupting the processing, which greatly improves the overall tea impurity removal efficiency.

[0032] Mounting plate 701 is fixedly installed on the side of the impurity removal box 1 away from the feed hopper 3, and the bottom ends of the two sets of connecting rods 709 are fixedly connected to the top of the screening frame 5.

[0033] The drying structure 8 includes a hot air blower 801 and an air supply pipe 802. The air outlet of the hot air blower 801 is fixedly connected to one end of the air supply pipe 802, and the other end of the air supply pipe 802 is fixedly connected to a diffuser 803. This allows the hot air blower 801, in conjunction with the air supply pipe 802 and the diffuser 803, to effectively dry the tea leaves inside the sieve frame 5 with hot air, thus preventing the tea leaves from becoming too moist and spoiling during subsequent storage.

[0034] The hot air blower 801 is fixedly installed on the top of the impurity removal box 1. The end of the air supply pipe 802 away from the hot air blower 801 passes through the top of the impurity removal box 1. The opening of the air diffuser 803 faces the inside of the screening frame 5.

[0035] Working Principle: During operation, tea leaves are continuously added to the screening frame 5 through the feed hopper 3, and the first motor 602 and the second motor 702 are started. The operation of the second motor 702 drives the eccentric wheel 703 to rotate. When the eccentric wheel 703 rotates, it can cooperate with multiple ball bearings 706 on its outer circumference to drive the top plate 707 to move up and down. The spring plate 705 is used to assist the top plate 707 to rebound and reset after moving down. When the top plate 707 moves up and down, it can cooperate with the movable rod 704 to drive the bottom plate 708 to move up and down, thereby cooperating with multiple sets of connecting rods 709 to drive the screening frame 5 to move up and down, assisting the vibration of the screening frame 5 and improving the tea impurity removal effect. Since the screening frame 5 is inclined, the screened tea leaves can be discharged directly through the opening side of the screening frame 5, and the screened impurities fall to the bottom. The bottom of the impurity removal box 1 discharges the tea leaves through the discharge chute 4, eliminating the need for manual discharge and allowing for continuous impurity removal without interrupting the process. This significantly improves the overall efficiency of tea impurity removal. During this process, the first motor 602 drives the turntable 603 to rotate, which in turn drives multiple feeding strips 604 to rotate. This evenly moves the tea leaves inside the screening frame 5 below the turntable 603, effectively preventing the tea leaves from piling up and affecting the impurity removal effect. Furthermore, during operation, the hot air blower 801, in conjunction with the air supply pipe 802 and the air diffuser 803, effectively dries the tea leaves inside the screening frame 5 with hot air, preventing excessive moisture in the tea leaves from causing spoilage during subsequent storage.
