The device includes: an adjusting groove and a telescopic slot; displacement rods are slidably connected within the adjusting groove and the telescopic slot; displacement levers are fixedly connected to the ends of the two sets of displacement rods; and constraint blocks are fixedly connected to the other ends of the two sets of displacement rods. A baffle plate slidably connected within the constraint slot of the U-frame further prevents tea from scattering from the side. The baffle plate can slide and adjust its position along the inner extension groove according to the sorting requirements. When fixed in position, it effectively removes the top layer of tea while blocking impurities in the bottom layer, facilitating layered tea sorting.

Description

Technical Field

[0001] This utility model belongs to the field of screening device technology, and more specifically, it relates to a tea screening device with automatic foreign object sorting function. Background Technology

[0002] In the tea production process, whether hand-picked or machine-picked, various foreign objects are inevitably mixed in. Therefore, efficient and accurate tea screening is a key link to ensure tea quality. Traditional tea screening methods mainly rely on manual screening and mechanical screening. However, manual screening requires relying on the naked eye and experience to pick out foreign objects from the tea leaves, which can easily lead to worker fatigue due to long working hours, thus affecting the accuracy and efficiency of screening. Machine screening can only separate impurities that fit the size of the screen. Therefore, a tea screening device is needed to facilitate the screening of tea leaves.

[0003] Based on existing technology, traditional screening devices mainly use vibration screening to process tea leaves. However, vibration screening causes the tea leaves to be layered, and the top layer of tea leaves is then removed to complete the screening. But because the removal process is based on the same standard, when the amount of tea leaves is small, the uniform standard will result in low tea removal efficiency, affecting the normal screening process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model relates to a tea screening device with an automatic foreign object sorting function. This device addresses the issue that vibration screening causes tea to be layered, and then the top layer of tea is removed to complete the tea screening. However, since the tea is on the same standard during the removal process, the uniform standard leads to low tea removal efficiency when the amount of tea is small, which affects the normal tea screening process.

[0005] This utility model provides a tea sorting device with automatic foreign object sorting function, which is achieved by the following specific technical means:

[0006] A tea sorting device with automatic foreign object sorting function includes: an outer frame; an auxiliary sleeve fixedly connected to the top of the outer frame; a docking U-frame fixedly connected to the opening of the outer frame; docking slots evenly spaced on the outer wall of the docking U-frame; a baffle plate slidably connected within the constraint slot of the docking U-frame; two sets of telescopic slots on the outer wall of the baffle plate; two sets of adjustment slots on the top of the baffle plate; displacement rods slidably connected within the two sets of adjustment slots and telescopic slots; displacement levers fixedly connected to the ends of the two sets of displacement rods; and constraint blocks fixedly connected to the other ends of the two sets of displacement rods respectively.

[0007] Preferably, the outer frame is configured as a U-shaped structure, and a rectangular plate is fixedly connected to the outer wall of the outer frame; an outer guide sleeve is fixedly connected to the bottom of the outer frame; the outer guide sleeve has an inclined surface inside; a screening plate is fixedly connected to the inner wall of the outer frame; and the auxiliary sleeve is configured as a U-shaped structure, and a rectangular plate is fixedly connected to the outer wall of the auxiliary sleeve.

[0008] Preferably, the docking U-frame is configured as a U-shaped structure; a rectangular constraint groove is provided on the inner wall of the docking U-frame; an inner extension groove is provided at the bottom of the docking U-frame; the inner extension groove is configured as a rectangular through hole, and the inner extension groove is connected to the constraint groove in the docking U-frame; the docking slot is configured as a rectangular through hole.

[0009] Preferably, the shielding plate is slidably connected to the inner extension groove; the inner extension groove is configured as a square plate structure; the two sets of telescopic slots are configured as rectangular grooves, and the two sets of telescopic slots are respectively connected to rectangular through holes, and the two sets of telescopic slots can be aligned with the docking slot.

[0010] Preferably, the two sets of adjustment grooves are configured as rectangular grooves, and the two sets of adjustment grooves are connected to the corresponding telescopic slots through circular through holes.

[0011] Preferably, the displacement rod is configured as a cylindrical rod structure; the two sets of displacement paddles are slidably connected in corresponding adjustment slots.

[0012] Preferably, the two sets of constraint blocks are slidably connected in corresponding telescopic slots, and the two sets of constraint blocks are respectively inserted into docking slots; a return spring is fixedly connected to each of the two sets of constraint blocks.

[0013] The tea sorting device with automatic foreign object sorting function proposed in this utility model has the following beneficial effects:

[0014] 1. The baffle plate that slides inside the U-shaped constraint groove further prevents tea leaves from scattering from the side. The position of the baffle plate can be adjusted along the inner extension groove according to the screening requirements. When the position is fixed, it can effectively discharge the top layer of tea leaves while blocking the impurities in the bottom layer, which facilitates the layered screening of tea leaves. During the screening process, as the tea leaves jump and roll on the screening plate, the blocking effect of the baffle plate can prevent the tea leaves from deviating from the screening area due to vibration.

[0015] 2. The auxiliary sleeve fixed to the top of the outer frame has a U-shaped structure. Its presence provides basic protection for tea screening. During the screening process, especially when the external vibration equipment causes the screening plate to vibrate violently, the auxiliary sleeve can effectively prevent tea leaves from splashing upwards and avoid them from falling out of the device. This keeps the screening work in a relatively closed and clean space, reduces tea waste and pollution to the working environment, and ensures that the tea leaves are always within a controllable range during the screening process.

Once the baffle 3 has slid to the desired position, the baffle 3 is fixed by operating the displacement lever 401. When the displacement lever 401 is moved, the displacement rod 4 moves within the adjustment groove 302 and the telescopic slot 301, thereby moving the constraint block 402. The return spring 403 then controls the constraint block 402 to insert into the docking slot 202, thus constraining and fixing the baffle 3 and preventing it from shifting during tea screening.

When screening tea, by connecting the external vibration device to the outer frame 1, the screening plate 102 can vibrate under the action of the vibration device. Under the action of the vibration device, some impurities in the tea are removed by the screening plate 102. At the same time, with the vibration, the heavy impurities mixed in the tea move down and are kept at the bottom of the outer frame 1 and blocked by the baffle plate 3. The top layer of tea is not affected by the baffle plate 3 and can be easily exposed to the outside, so as to facilitate the screening of tea.
