Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a multi-stage speed control mechanism for a tea shaker. Background Technology

[0002] A tea shaker is a mechanical device used in tea processing. It primarily screens, grades, and mixes tea leaves during the shaking process to improve their quality and consistency. Through rotation and vibration, it continuously tumbles the tea leaves on a screen, removing impurities, separating tea particles of different sizes, and ensuring uniform mixing. Tea shakers are typically motor-driven and feature adjustable shaking frequency and amplitude to accommodate the processing needs of different types and grades of tea.

[0003] In the tea processing process, some tea shaking machines control the speed through a gearbox. Usually, lubricating oil is added manually to lubricate the inside of the gearbox. However, manually adding lubricating oil cannot guarantee that the gear sets inside the gearbox are adequately lubricated, which can easily lead to some gear sets lacking lubrication, increasing the risk of wear and affecting the service life of the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-stage speed control mechanism for a tea shaking machine.

[0005] This utility model is achieved using the following technical solution: a multi-stage speed control mechanism for a tea shaking machine, comprising a shaking cage, with fixed rods fixedly connected to both ends of the shaking cage, a support frame rotatably connected to the surface of the fixed rods, a fixed base fixedly connected to the bottom of the support frame, a motor provided at the right end of the support frame, a mounting plate fixedly connected to the right end of the support frame, a gearbox fixedly connected to the top of the mounting plate, a lubrication assembly provided at the rear end of the gearbox, a filter assembly provided at the bottom of the mounting plate, two symmetrically arranged reinforcing ribs fixedly connected to the bottom of the mounting plate, and a PLC controller fixedly connected to the front end of the reinforcing ribs.

[0006] The lubrication assembly includes an oil pump, with an oil suction pipe connected to the bottom of the oil pump and an oil delivery pipe connected to the top of the oil pump. One end of the oil delivery pipe extends into the interior of the gearbox and is connected to an oil injection pipe.

[0007] With the above technical solution, when it is necessary to lubricate the gear set inside the gearbox, the oil pump is started. The oil pump draws lubricating oil from the oil tank through the oil extraction pipe and sends it into the oil injection pipe through the oil delivery pipe. The lubricating oil is then evenly sprayed out through several oil outlet holes to lubricate the gears in different positions inside the gearbox, reduce wear, and extend the service life of the equipment.

[0008] As a further improvement to the above solution, the output end of the motor is fixedly connected to the input end of the gearbox, the output end of the gearbox is fixedly connected to the left end of the fixed rod, and a through groove is provided at the bottom of the gearbox.

[0009] With the above technical solution, the left end of the motor is fixed to the right end of the gearbox. Since the output end of the motor is fixedly connected to the input shaft of the gearbox, the output shaft of the gearbox drives the fixed rod to rotate, causing the shaking cage to rotate. The gearbox has multiple sets of gears inside. By switching different gear combinations, the speed of the output shaft can be changed, thus realizing the adjustment of the speed. The PLC controller controls the speed of the motor through programming, realizing multi-stage speed control to meet different needs in the tea shaking process.

[0010] As a further improvement to the above solution, the front end of the oil pump is fixedly connected to the rear end of the reinforcing rib plate, and the left end of the reinforcing rib plate is fixedly connected to the right end of the support frame.

[0011] The above technical solution improves the structural strength of the mounting plate by using reinforcing ribs.

[0012] As a further improvement to the above solution, the two ends of the fuel injection pipe are fixedly connected to the inner wall of the gearbox, and several oil outlet holes are opened at the bottom of the fuel injection pipe.

[0013] With the above technical solution, the oil injection pipe is located above the gear set inside the gearbox, and lubricating oil is sprayed to different positions through several oil outlet holes to ensure that all gears inside the gearbox are lubricated.

[0014] As a further improvement to the above solution, the filter assembly includes an oil storage tank, the inner wall of which is provided with a groove, a filter screen is slidably connected to the inner wall of the groove, and a limit plate is fixedly connected to one end of the filter screen.

[0015] The above technical solution filters debris or impurities in the lubricating oil through the filter screen inside the oil tank, ensuring the cleanliness of the lubricating oil used subsequently. Since the filter screen is slidably connected to the slide groove, it is easy to slide it out for maintenance.

[0016] As a further improvement to the above solution, the top of the oil tank is fixedly connected to the bottom of the mounting plate, the oil tank is connected to the bottom of the gearbox through a through groove, and a handle is fixedly connected to one end of the limiting plate.

[0017] With the above technical solution, since the oil tank is connected to the gearbox, the lubricating oil after spraying can flow back into the oil tank for recycling. The filter screen can be easily pulled out by the handle, which improves the ease of operation.

[0018] As a further improvement to the above scheme, the end of the oil extraction pipe away from the oil pump is connected to the oil storage tank.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention incorporates a lubrication system. Specifically, by activating an oil pump, the pump draws lubricating oil from the oil tank through an oil extraction pipe and delivers it into the spray pipe through an oil delivery pipe. The lubricating oil is then evenly sprayed out through several oil outlets to lubricate the gears at different locations within the gearbox, reducing wear and extending the equipment's service life.

[0021] This utility model incorporates a filter assembly. Specifically, the sprayed lubricating oil flows into the oil storage tank through a channel, and a filter screen filters out debris from the lubricating oil, ensuring its cleanliness and preventing impurities from affecting the oil pump and the gear set inside the gearbox. A handle at one end of the limiting plate allows the filter screen to be easily slid out for cleaning or replacement, improving the convenience of maintenance. Attached Figure Description

The bottom of the oil pump 801 is connected to an oil suction pipe 802, and the top of the oil pump 801 is connected to an oil delivery pipe 803. One end of the oil delivery pipe 803 extends into the interior of the gearbox 6 and is connected to an oil injection pipe 804. When the motor 5 is started, its output end is fixedly connected to the input shaft of the gearbox 6, causing the output shaft of the gearbox 6 to drive the fixed rod 2 to rotate, thus rotating the crank cage 1. The gearbox 6 has multiple sets of gears inside; by switching different gear combinations, the rotational speed of the output shaft can be changed to achieve… To adjust the rotation speed, the PLC controller 11 controls the speed of the motor 5 through programming, realizing multi-stage speed control to meet different needs during the tea shaking process. When it is necessary to lubricate the gear set inside the gearbox 6, the oil pump 801 is started. The oil pump 801 draws lubricating oil from the oil storage tank 901 through the oil extraction pipe 802 and sends it into the oil spray pipe 804 through the oil delivery pipe 803. The lubricating oil is evenly sprayed out through several oil outlet holes to lubricate the gears at different positions inside the gearbox 6, reduce wear, and extend the service life of the equipment.

[0033] The output end of the motor 5 is fixedly connected to the input end of the gearbox 6, the output end of the gearbox 6 is fixedly connected to the left end of the fixed rod 2, and a through groove is provided at the bottom of the gearbox 6.
