[0005] The beneficial effects of the utility model are:

[0006] Fresh tea is loaded through the feeding end of the feeding plate and moves in the separation box. The heat from the heating box is dissipated through the air holes and the air mesh at the filter to dry the tea. The heat dissipation rate is reduced by pulling the sliding door, and the working conditions in the separation box can be observed through the inspection window. At the same time, the fine tea powder produced can be filtered at the filter port of the filter through the curved filter, so that the tea leaves are separated from the fine powder, which is beneficial to improving the quality of the tea. The tea leaves that fall into the filter are cleaned by the left and right movement of the sweeping wheel. Collection boxes are set at the left and right ends of the filter to collect the tea. The size of the filter port at the filter is controlled by the up and down movement of the main rod. Therefore, by increasing the number of transport boxes, the filter port size of tea of ​​different qualities can be controlled to prevent blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings 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 shall fall within the scope of protection of the present invention.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example

[0018] Reference Figure 1-Figure 7 According to an embodiment of the present invention, a machine for removing impurities before tea frying includes a transport box 10, a feeding plate 11 is fixedly provided at the upper end of the transport box 10, a sliding door 12 that can be slid open is provided at the upper end of the transport box 10, and an inspection window 27 is provided on the rear end surface of the transport box 10. A separation box 13 is fixedly provided in the transport box 10, and a heating box 14 is provided at the lower end of the separation box 13. Air holes 25 are evenly distributed front and back are opened on the separation box 13, and the air holes 25 are connected to the heating box 14. Arc-shaped clamps 19 are evenly distributed front and back are fixed in the separation box 13, and the opening of the arc-shaped clamp 19 is arranged upward. The upper end of each arc-shaped clamp 19 is abutted with a filter screen 20, and the filter screen 20 is squeezed at the upper end by the arc-shaped clamp 19 to form a uniformly distributed filter port, and two adjacent filter ports A breathable net is provided in between, and a threaded rod 22 is provided in each arc-shaped clamping cylinder 19, and a cleaning wheel 21 is threadedly connected to the outer periphery of each threaded rod 22, and bristles are provided on the outer periphery of the cleaning wheel 21. A power box is provided at the front end of the transport box 10, and a power source is provided in the power box. The power source is connected to the threaded rod 22 for power. The front and rear ends of the transport box 10 are provided with two front-to-rear symmetrical lifting grooves 26, and each lifting groove 26 is embedded with a cylinder 16. The upper end of each cylinder 16 is connected with a spring telescopic rod 15, and the upper ends of the two spring telescopic rods 15 are connected with a lifting plate 17. A main rod 23 is fixed between the two adjacent lifting plates 17, and a bracket pressure rod 24 evenly distributed on the left and right is fixed on the lower end surface of the main rod 23. The bracket pressure rod 24 abuts against the upper end of the filter screen 20;

[0019] The tea leaves slide downward through the feeding plate 11 and fall into the separation box 13 fixed on the conveying box 10. The heating box 14 is energized to heat the air and release it upward through the filter screen 20. The heated air passes through the air vents 25 and enters the separation box 13 to dry the tea leaves on the separation box 13. The lifting slot 26 is energized to control the spring telescopic rod 15 to extend and retract, thereby driving the lifting plates 17 at the left and right ends to slide up and down. The lifting plates 17 simultaneously drive the fixedly connected main rod 23 to move up and down, and the support pressure rod 24 fixed at the lower end of the main rod 23 abuts against the filter screen 20. The main rod 23 moves downward, and the support pressure rod 24 pressurizes the filter screen 20, reducing the filter port width between the two filter screens 20, changing the filtration performance of the filter screen 20, so that small particles of broken tea leaves pass through the filter port and fall into the filter screen 20. Figure 7 As shown, the cleaning wheel 21 falls to the position of the cleaning wheel 21, and the power source in the power box controls the rotation of the threaded rod 22, so that the cleaning wheel 21, which is threadedly connected to the threaded rod 22, moves left and right. The cleaning wheel 21 cleans the broken tea leaves in the filter 20 and moves left and right. The broken tea leaves are discharged outward from the left and right notches of the filter 20, and the collection box is prevented from collecting the broken tea leaves below the left and right notches of the filter 20.

[0020] By arranging multiple transport boxes 10 on the left and right or multiple transport boxes 10 on the top and bottom, a conveying plate is connected between two adjacent transport boxes 10. The conveying plate is used to transfer the tea leaves on the upper end surface of the filter 20 left and right or up and down, and the lifting height of the threaded rod 22 on each transport box 10 is controlled respectively, so as to adjust the size of the filter opening at the filter 20. The tea leaves are transported from left to right, and the size of the filter opening increases from left to right or from top to bottom, so that broken tea leaves, small pieces of tea leaves and large pieces of tea leaves are screened in turn.

[0021] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All such modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims appended hereto.
