[0024] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] See also Figure 1 、 Figure 2 and Figure 3, a new type of screen heating structure of a crawler mobile heavy-duty screening station, including a screening station body 1 and an industrial hot air blower 2, the screening station body 1 and the industrial hot air blower 2 are existing devices, and no further details will be given here. The screening station body 1 is used to screen materials, and the industrial hot air blower 2 is used to generate hot air, and the hot air is introduced into the industrial hot air blower 2 through existing connecting parts such as pipes to thaw the frozen materials. A heavy-duty screen 11 is provided at the upper end of the screening station body 1, and symmetrical air inlets 12 are respectively provided at the front and rear ends of the screening station body 1. The air outlet of the industrial hot air blower 2 is connected to the air inlet 12 through a pipe, and the air outlet position of the industrial hot air blower 2 is connected to the air inlet 12 of the screening station body 1 through a pipe. The industrial hot air blower 2 generates Hot air is introduced into the air inlet 12 through a pipe, and is blown toward the screen 13 through the air outlet 3 to thaw the frozen material on the screen 13. The lower end of the heavy screen 11 is provided with a screen 13 connected to the screening station body 1, and the inner wall of the screening station body 1 is connected to the air inlet 12 with an air outlet 3. The air outlet 3 is located above the screen 13, and the air inlet 12 is connected to the frame 31 in a one-to-one manner. The air inlet 12 is located in the center of the frame 31. The screen 13 is used to screen the material and separate the qualified material from the unqualified material. At the same time, the air outlet 3 is set at the upper end of the screen 13 to facilitate the hot air to be blown to the upper end of the screen 13 through the air outlet 3, thereby ensuring that the frozen material on the upper end of the screen 13 is thawed and preventing the frozen material from clogging the screen 13.

[0026] See also Figure 4 、 Figure 5 、 Figure 6 and Figure 7The air outlet 3 includes a right-angled triangle frame 31. By setting the frame 31 to a right-angled triangle, the stability of the air outlet 3 is achieved when the air outlet 3 is fixed. At the same time, the two right-angled surfaces of the frame 31 can be provided with through holes to discharge hot air, which is convenient for hot air to be discharged from multiple angles, so that the hot air is evenly blown to the surface of the screen 13. The first windshield 32, the second windshield 33 and the third windshield 34 are rotatably connected to the long right-angled surface of the frame 31, and gaps are provided between the two. The first guide plate 35 and the third windshield 34 are symmetrically provided on the inner side of the frame 31. The second guide plate 36, the first guide plate 35 and the second guide plate 36 divide the frame 31 into three parts, and at the same time guide the hot air entering the frame 31 from the air inlet 12, so that the hot air is evenly discharged through the frame 31. At the same time, the gap between the two second guide plates 36 is smaller than the gap distance from the second guide plate 36 to the edge of the air inlet 12, so that the air inlet 12 is divided into three parts, ensuring that the hot air entering the three parts of the frame 31 is consistent, and preventing local overheating. The second guide plate 36 is S-shaped, the first guide plate 35 is arc-shaped, and the second guide plate 36 is S-shaped. The second guide plate 36 and the first guide plate 35 are fixedly connected to the frame 31, and the gap between the two second guide plates 36 is opposite to the air inlet 12. The gap between the two second guide plates 36 is smaller than the gap distance from the second guide plate 36 to the edge of the air inlet 12. The gaps between the first wind shield 32, the second wind shield 33 and the third wind shield 34 and the gaps between them and the frame 31 are parallelograms and have different inclination angles. The gaps between the first wind shield 32, the second wind shield 33 and the third wind shield 34 and the gaps between them and the frame 31 are set to be parallelograms. The quadrilaterals are arranged in a row with different inclination angles, which is conducive to the hot air blown out through the spacing to be evenly blown onto the screen 13, preventing the ice material from blocking the screen 13. At the same time, the first wind shield 32, the second wind shield 33 and the third wind shield 34 are rotatably connected to the frame 31, thereby realizing the adjustment of the angles of the first wind shield 32, the second wind shield 33 and the third wind shield 34, and then adjusting the position where the hot air is blown. When the screen 13 is partially blocked by ice material, the angles of the first wind shield 32, the second wind shield 33 and the third wind shield 34 are adjusted so that most of the hot air is blown to the blocked position, which is convenient for adjustment.

[0027] See also Figure 4 and Figure 9The right ends of the first wind deflector 32, the second wind deflector 33 and the third wind deflector 34 are respectively provided with a limit assembly 4, the limit assembly 4 includes a limit wheel 41, a limit column 42 and a fixed column 43, the limit wheel 41 is respectively fixedly connected to the first wind deflector 32, the second wind deflector 33 and the third wind deflector 34, the limit wheel 41 is meshed with the limit column 42, one end of the limit column 42 is provided with a gear meshed with the limit wheel 41, the other end of the limit column 42 is provided with a protrusion, which is convenient for moving the limit column 42 to release the meshing of the limit column 42 and the limit wheel 41, the limit column 42 is slidably connected with the fixed column 43, the limit wheel 41 is a half gear, the interior of the limit column 42 is provided with a through hole and a compression spring 44 is fixed in the through hole, one end of the compression spring 44 is fixedly connected to the limit column 42 Then, the other end of the compression spring 44 is fixedly connected to the fixing post 43, and the compression spring 44 pushes the limit post 42 to move, so that the limit post 42 is engaged with the limit wheel 41, limiting the limit wheel 41 so that it no longer rotates, thereby achieving the fixation of the frame 31, the first wind deflector 32 and the second wind deflector 33. The limit post 42 is slidably connected to the fixing post 43 through the through hole, and the fixing post 43 is fixed on the frame 31. When the limit between the limit post 42 and the limit wheel 41 is released, it is only necessary to pull the limit post 42, and the limit post 42 slides with the fixing post 43. At this time, the limit post 42 moves away from the limit wheel 41, releasing the limit on the limit wheel 41. After the limit post 42 is released, the compression spring 44 still pushes the limit post 42 to engage with the limit wheel 41, and re-limits the limit post 42.

[0028] When using this utility model:

[0029] First, based on the previous experience of the screening station body 1 in screening frozen materials, roughly determine the location where the frozen materials are concentrated and blocked on the screen 13;

[0030] Then, the limiting post 42 is pulled, and the limiting post 42 and the fixed post 43 slide. At this time, the limiting post 42 is away from the limiting wheel 41, and the compression spring 44 is compressed, releasing the limit on the limiting wheel 41, and swinging the inclination angle of the first wind deflector 32 so that the gap of the first wind deflector 32 is facing the position where the material is concentratedly blocked on the screen 13. After the limiting post 42 is released after adjustment, the compression spring 44 still presses against the limiting post 42 and engages with the limiting wheel 41, and the limiting post 42 is limited again. After the first wind deflector 32, the second wind deflector 33 and the third wind deflector 34 are adjusted in sequence;

[0031] Next, a pipe is used to connect the industrial hot air blower 2 and the air inlet 12. The hot air generated by the industrial hot air blower 2 enters the air inlet 12 and is blown out from the gaps between the first wind shield 32, the second wind shield 33 and the third wind shield 34.

[0032] Finally, the screening station body 1 is started to work. When the frozen material comes onto the screen 13, the hot air blown out through the gaps between the first wind shield 32, the second wind shield 33 and the third wind shield 34 thaws the frozen material, effectively preventing the screen 13 from being blocked.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
