Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea sieving technology, and in particular to a tea sieving machine. Background Technology
[0002] Tea sieving is a process in tea processing, and sieving machines are used to sieve tea leaves during the production and processing of tea.
[0003] Existing tea sieving machines have the following shortcomings in use:
[0004] Tea sieving machines typically sieve tea leaves at the same horizontal level. However, this is inconvenient if sieving is required at different angles. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that existing tea sieving machines usually sieve tea at the same horizontal line when vibrating and sieving, which is inconvenient when sieving at different angles. Therefore, a new tea sieving machine is proposed.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A tea sieving machine includes a machine body, a circular plate on the top of the machine body, a fixed frame fixedly mounted on the top of the circular plate, a plurality of springs fixedly mounted on the top of the fixed frame, the plurality of springs being arranged in a ring, a common placement plate fixedly mounted on the top of the plurality of springs, a collection box placed on the top of the placement plate, a sieving box mounted on the collection box, a limit ring fixedly mounted on the bottom of the sieving box, a limit groove formed on the top of the collection box, the limit ring being inserted into the limit groove, a plurality of sieving holes formed on the bottom of the sieving box, and a T-shaped cover placed on the top of the sieving box.
[0008] An adjustment mechanism is located on the top of the machine body to adjust the angle of the placement plate, facilitating screening at different angles.
[0009] The fixing mechanism is set on the placement plate to press down and fix the cover.
[0010] Preferably, the adjustment mechanism includes a connecting frame, a first hinge seat, an electric push rod, and a second hinge seat. The bottom of the connecting frame is fixedly connected to the top of the machine body. One side of the first hinge seat is welded to one side of the connecting frame. The top of the second hinge seat is welded to one side of the bottom of the circular plate. The fixed part of the electric push rod is hinged to the first hinge seat, and the telescopic part of the electric push rod is hinged to the second hinge seat. The same rotating rod is rotatably connected to the inner walls of both sides of the connecting frame. A connecting plate is welded to one side of the rotating rod, and the top of the connecting plate is welded to the center of the bottom of the circular plate.
[0011] Preferably, the fixing mechanism includes two threaded rods, two nuts, and a lower pressure plate. The bottom ends of the two threaded rods are welded to the top two sides of the placement plate, respectively. Both ends of the lower pressure plate are provided with through holes. The lower pressure plate is sleeved on the threaded rods through the through holes. The two nuts are threadedly connected to each other. Both sides of the nuts are welded with torsion plates to facilitate the rotation of the nuts.
[0012] Preferably, a vibration motor for causing the placement plate to vibrate is fixedly installed at the bottom center of the placement plate.
[0013] Preferably, a positioning ring for positioning the collection box is fixedly provided on the top of the placement plate, and the collection box is located inside the positioning ring.
[0014] Preferably, each of the four corners of the bottom of the machine body is fixedly provided with a support foot, and the bottom of the support foot is fixedly provided with a rubber pad for anti-slip.
[0015] In this application, during use, the tea sieving machine is placed on a stable workbench, ensuring that the four support legs provide stable support and that the rubber pads are in close contact with the table surface to prevent slippage. The collection box is placed on top of the placement plate, ensuring that the collection box is positioned within the positioning ring. The sieving box is then placed on top of the collection box, ensuring that the limiting ring at the bottom of the sieving box is correctly inserted into the limiting groove at the top of the collection box. The tea to be sieving is poured into the sieving box. The T-shaped cover is placed on top of the sieving box to close the sieving space. Then, the lower pressure plate is fitted onto the two threaded rods and placed on the cover. The two nuts are then rotated to move downwards along the threaded rods and tighten on both sides of the lower pressure plate, thereby fixing the cover in place. Turn on the vibration motor to vibrate the placement plate and the sieving box on it. The vibration helps the tea leaves to be evenly separated through the sieving holes. Broken tea leaves and debris fall into the collection box through the sieving holes, while whole tea leaves remain in the sieving box. During the sieving process, according to the sieving requirements, start the electric push rod. The telescopic part of the electric push rod pushes the second hinge seat, which in turn drives the circular plate and the placement plate to rotate around the rotating rod to the required angle. This allows the angle of the placement plate to be adjusted for sieving at different angles. After sieving is completed, turn off all power, loosen the nut, and remove the lower pressure plate and cover. It should be noted that the vibration motor and electric push rod require an external controller and an external power supply for operation.
[0016] In this utility model, the tea sieving machine, through the adjustment mechanism, starts the electric push rod, the telescopic part of the electric push rod pushes the second hinge seat, thereby driving the circular plate and the placement plate to rotate around the rotating rod to the required angle, so that the angle of the placement plate can be adjusted to facilitate sieving at different angles;
[0017] In this utility model, the tea sieving machine uses a fixing mechanism to place the lower pressure plate on two threaded rods and onto the cover. Then, two nuts are rotated to move them downwards along the threaded rods and fasten them to both sides of the lower pressure plate, thereby fixing the cover.
[0018] In this invention, the angle of the placement plate can be adjusted by the adjustment mechanism to facilitate sieving at different angles, and the cover can be fixed by the fixing mechanism. Attached Figure Description
