Description

Technical Field

[0001] The utility model relates to the technical field of tea processing, in particular to a high-efficiency tea processing and screening device. Background Art

[0002] Screening devices in tea processing are mainly used to separate tea leaves of different sizes to ensure the uniformity and quality of the tea.

[0003] For example, an efficient tea processing and screening device disclosed in the authorization announcement number CN216297071U includes a machine body, a feed port is provided at the top of the machine body, a fixed frame is fixedly connected to the side of the machine body, filter screen 1 and filter screen 2 are fixedly connected to the inner wall of the machine body, a vibration device is provided at the outer end of filter screen 1, and a collection box is passed through and slidably connected to the side wall of the fixed frame. After adopting the above technical solution, the beneficial effect of the utility model is as follows: the device can periodically knock filter screen 1 and filter screen 2 during filtering, and in conjunction with the vibration device, filter screen 1 and filter screen 2 can be vibrated, so that the tea stuck in the filter hole is vibrated and falls off, and the speed of the tea leaves discharged from the inclined surface of the filter screen is accelerated, which is more convenient and quick.

[0004] Although the above patent can screen by vibration, since the filter is placed at an angle, when vibrating, the tea leaves will float up after being vibrated and move toward the lower side. In this way, the unfiltered tea leaves may fall to the discharge port, resulting in incomplete screening. Utility Model Content

[0005] The purpose of the present invention is to provide an efficient tea processing and screening device to solve the problems raised in the above background technology.

During screening, the tea is put into the feeding port at the upper end of the screening box, and the intermittent fan is started. After the intermittent fan is started, intermittent compressed air enters the air pipe, enters the cannula through the air pipe, and enters the two sleeves at the same time through the connecting pipe. The gas lifts the piston rod, and the screen vibrates after the piston rod is lifted, thereby screening the tea leaves that fall on the screen. Since baffles are provided above both sides of the screen, the tea leaves will not be discharged from the discharge port on the right side during vibration, thereby achieving the purpose of facilitating screening.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-4 As shown, the utility model provides a technical solution:

[0025] The tea leaves are put into the tea box 1 and the tea leaves are put into the tea box 1. The tea leaves are put into the tea box 1 and the tea leaves are put into the tea box 1. The tea leaves are put into the tea box 1 and the tea leaves are put into the tea box 1. The tea leaves are put into the tea box 1 and the tea box 1 is put into the tea box 1.

[0026] In this embodiment, during screening, tea leaves are put into the feeding port at the upper end of the screening box 1, and the intermittent fan 11 is started. After the intermittent fan 11 is started, intermittent compressed air enters the air pipe 9, enters the cannula 8 through the air pipe 9, and enters the two sleeves 4 at the same time through the connecting pipe 7. The gas lifts the piston rod 5, and the piston rod 5 vibrates the screen 2 after being lifted, thereby screening the tea leaves that fall on the screen 2. Since baffles 16 are provided above both sides of the screen 2, the tea leaves will not be discharged from the discharge port 17 on the right side during vibration, thereby achieving the purpose of facilitating screening.

[0027] like Figure 2 and Figure 3 As shown, the screening box 1 is provided with a blowing mechanism on the left side near the screen 2, and the blowing mechanism includes an intermittent fan 11, which is provided on the outside of the lower left side of the screening box 1, and the air outlet end of the intermittent fan 11 is connected to the lower end of the air supply pipe 9. A plurality of nozzles 12 are arranged side by side on the inner wall of the upper left end of the screening box 1 near the screen 2, and the top of the air supply pipe 9 is connected with an air inlet pipe 13, and the air inlet pipe 13 is connected to the plurality of nozzles 12. A switch valve 14 is provided on the top of the air supply pipe 9, and the material blocking mechanism includes an electric push rod 15, which is symmetrically provided on both sides of the top of the screening box 1, and a baffle 16 is provided at the output shaft end of the two electric push rods 15. A discharge port 17 is provided on the right side of the screening box 1 near the screen 2, and a discharge port 2 18 is provided on the lower right side of the screening box 1;

[0028] In this embodiment, when the tea screening is completed, the electric push rod 15 is started, and the electric push rod 15 lifts the baffle 16, so that the nozzle 12 and the discharge port 17 are opened, and then the switch valve 2 10 is closed, and the switch valve 14 is started. At this time, the gas in the gas pipe 9 enters the air inlet pipe 13 and is ejected through several nozzles 12, so that the large volume of tea leaves intercepted by the screen 2 is ejected from the discharge port 17, and after the air flow passes through the screen 2, the tea leaves that have been screened at the bottom of the screening box 1 can also be ejected from the discharge port 2 18, thereby achieving the purpose of facilitating and quickly unloading.

[0029] Working principle: When screening, put the tea leaves into the feeding port at the upper end of the screening box 1 and start the intermittent fan 11. After the intermittent fan 11 is started, intermittent compressed air enters the air pipe 9, enters the cannula 8 through the air pipe 9, and enters the two sleeves 4 at the same time through the connecting pipe 7. The gas lifts the piston rod 5, and the piston rod 5 vibrates the screen 2 after lifting, and then the tea leaves falling on the screen 2 are screened. Since baffles 16 are provided above both sides of the screen 2, the tea leaves will not be discharged from the right side during vibration. The tea leaves are discharged from the outlet 17. When the tea leaves are screened, the electric push rod 15 is started, and the electric push rod 15 lifts the baffle 16 to open the nozzle 12 and the outlet 17. Then the switch valve 10 is closed and the switch valve 14 is started. At this time, the gas in the air supply pipe 9 enters the air inlet pipe 13 and is ejected through a number of nozzles 12, so that the large volume of tea leaves trapped by the screen 2 are ejected from the outlet 17. After the air flow passes through the screen 2, the tea leaves screened at the bottom of the screening box 1 can be ejected from the outlet 18.
