[0025] As Figure 3 As shown, the inner wall of screening box 1 is fixedly connected with a plurality of supports 2;Rotary rod 21 is rotatably connected in the inside of support 2;Rotary rod 21 is set as damping;Net baffle 22 is fixedly connected on the side wall of rotary rod 21;Net baffle 22 is set as arc rigidity.Working, move net baffle 22 to the appropriate position above jet nozzle 18, and fix by the damping setting of rotary rod 21, to block the impurities such as broken leaf and dust in the screening process from entering jet nozzle 18;When jet nozzle 18 blows upward, airflow blows upward through the aperture in the inside of net baffle 22, and at the same time, the arc setting of net baffle 22 also plays a certain flow guiding effect, so that the airflow blown by jet nozzle 18 can be more accurately blown to the required position;By setting rotary rod 21 with damping, net baffle 22 can be fixed at the required position and not affected by airflow;By setting arc rigid net baffle 22, a part of impurities such as broken leaf and dust in the screening process can be blocked from entering jet nozzle 18, reducing the problem of mechanical blockage caused by impurities attachment;At the same time, the arc setting of net baffle 22 also plays a certain flow guiding effect, so that the airflow blown by jet nozzle 18 can be more accurately blown to the required position.
[0026] As Figure 1As shown, the outside wall of the screening box 1 is fixed with a plurality of heating blocks 3; the heating blocks 3 are symmetrically arranged on the outside wall of the screening box 1. When the screening operation is carried out inside the screening box 1, the heating blocks 3 are opened to heat and dry the inside of the screening box 1, so that the leaves adhered to each other due to moisture can be separated from each other, and the air inside the screening box 1 can be heated and dried to reduce the moisture inside. Through the arrangement of the heating blocks 3, the air inside the screening box 1 can be heated and dried to reduce the problems of leaf moisture and damage caused by excessive moisture inside the screening box 1. At the same time, the arrangement of the heating blocks 3 can also separate the leaves adhered to each other due to moisture, reducing the problem of being unable to screen due to leaf adhesion.
[0027] As shown in Figure 4 , the inside wall of the screening box 1 is fixed with a cross-shaped partition plate 4; the cross-shaped partition plate 4 is arranged below the air jet nozzle 18. When the screening operation is carried out inside the screening box 1, the cross-shaped partition plate 4 divides the inside of the screening box 1 into a plurality of areas, so that the broken leaves, dust and other impurities generated during the screening operation fall into each area, reducing the secondary pollution caused by the blowing of the screened impurities due to excessive air flow. At the same time, after the screening operation is completed, the screened impurities can be checked one by one in sequence to determine whether there are complete leaves required to be collected. Through the arrangement of the cross-shaped partition plate 4, the broken leaves, dust and other impurities generated during the screening operation can be uniformly collected in each area, reducing the secondary pollution caused by the blowing of the screened impurities due to excessive air flow. At the same time, the arrangement of the cross-shaped partition plate 4 can be used for secondary inspection after the work is completed, reducing the problem of material waste.
[0028] As shown in Figure 4 , the inside bottom of the screening box 1 is provided with a sponge pad 5; the sponge pad 5 is arranged at the bottom of the cross-shaped partition plate 4. When the impurities enter the inside of the cross-shaped partition plate 4, the sponge pad 5 can increase the adsorption of the impurities, so that they are less likely to leave the inside of the cross-shaped partition plate 4, reducing the secondary pollution caused by the blowing of the screened impurities due to excessive air flow. Through the arrangement of the sponge pad 5, the adsorption of the sponge pad 5 is used to increase the adsorption of the impurities, so that they are less likely to leave the inside of the cross-shaped partition plate 4, reducing the secondary pollution caused by the blowing of the screened impurities due to excessive air flow. At the same time, the arrangement of the sponge pad 5 also plays a certain buffering and protection role for the machine and materials.
[0029] As shown in Figures 4 to 5As shown, the screening box 1 side wall is provided with a plurality of pipe holes 6; the pipe hole 6 is internally slidably connected with a water pipe 61; the water pipe 61 side wall is provided with a plurality of water outlets 62; the pipe hole 6 end is communicated with a water inlet pipe 63. The water pipe 61 is located inside the sponge pad 5 and is in sliding fit with the sponge pad 5. In working, the water pipe 61 is put into the sponge pad 5 through the pipe hole 6, the water inlet pipe 63 is connected to the water pump, so that the water flows through the water pipe 61 and is discharged into the sponge pad 5 through the water outlet 62, and the sponge pad 5 is wetted. The wet sponge pad 5 can increase the adsorption of dust and other impurities, so that it is less likely to be blown out of the cross-shaped partition plate 4. The water pipe 61 can wet the sponge pad 5, the wet sponge pad 5 can increase the adsorption of dust and other impurities, so that it is less likely to be blown out of the cross-shaped partition plate 4, and the secondary pollution caused by the too large airflow blowing up the screened impurities is reduced.
[0030] Working principle: when working, first, the required screening tea is evenly and fully laid on the screen 12, and is put into the screening box 1 through the chute 11; first step, the fan 14 is opened, so that the air blows to the screen 12, at this time, the screen 12 is concave downward, and part of impurities is screened out through the screen 12; second step, the fan 14 is closed, at the same time, the air inlet pipe 17 is connected to the air pump, and air is ventilated into the inflation bin 16, and then is blown to the screen 12 by the air jet nozzle 18, at this time, the screen 12 is convex upward, and drives the tea and impurities on the screen 12 to move upward; the two steps are repeated, so that the tea continuously reciprocates on the screen 12 to achieve the screening effect; when working, the mesh baffle 22 is moved to the appropriate position above the air jet nozzle 18, is fixed through the damping setting of the rotating rod 21, and blocks the impurities such as broken leaves and dust in the screening process from entering the air jet nozzle 18; when the air jet nozzle 18 blows upward, the airflow blows upward through the pores in the mesh baffle 22, at the same time, the arc-shaped arrangement of the mesh baffle 22 also has a certain flow guiding effect, so that the airflow blown by the air jet nozzle 18 can be more accurately blown to the required position; when the screening box 1 is screening, the heating block 3 is opened, the inside of the screening box 1 is heated and dried, so that part of the leaves that are adhered to each other due to moisture can be separated from each other, and the air in the screening box 1 can also be heated and dried to reduce the humidity inside; when the screening box 1 is screening, the cross-shaped partition plate 4 divides the inside of the screening box 1 into multiple areas, so that the impurities such as broken leaves and dust generated in the screening operation fall into each area, reducing the secondary pollution caused by the airflow being too large to blow the screened impurities; at the same time, after the screening operation is completed, the screened impurities can be checked one by one according to the area sequence to see whether there are required complete leaves, so as to be collected; when the impurities enter the inside of the cross-shaped partition plate 4, the sponge pad 5 can increase the adsorption of the impurities, so that the impurities are less likely to be blown out of the inside of the cross-shaped partition plate 4, reducing the secondary pollution caused by the airflow being too large to blow the screened impurities; when working, the water pipe 61 is put into the inside of the sponge pad 5 through the pipe hole 6, the water inlet pipe 63 is connected to the water pump, so that the water flows through the water pipe 61 and is discharged into the sponge pad 5 through the water outlet hole 62, and the sponge pad 5 is wetted. The wet sponge pad 5 can increase the adsorption of the dust and other impurities, so that the impurities are less likely to be blown out of the inside of the cross-shaped partition plate 4.
