[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0030] Refer to Figure 1 , which is a schematic structural diagram of an existing hot air drying system. The drying system includes a box body member 100. The box body member 100 has an air inlet 100a and an air outlet 100b at the position of the right side wall, and openings for the conveyor belt 101 to pass through are provided on the front and rear side walls of the box body member 100. During the operation of the hot air drying system, dry hot air enters the box body from the air inlet of the box body member 100 and flows upward to contact the materials on the conveyor belt 101 and then becomes wet air and is discharged from the air outlet 100b to achieve the drying of the materials. Further, in order to ensure the full contact between the hot air and the materials in the box body member 100, a raking mechanism is fixed in the box body member 100 of the existing drying system. The raking mechanism is used to loosen the material stack on the conveyor belt 101. However, due to the fixed position height of the raking mechanism, when the height of the material stack on the conveyor belt changes, the materials in some stacks are difficult to be loosened, thus affecting the drying effect of the materials. Based on this, the present application proposes a raking mechanism applicable to a hot air drying system to solve the above problems

[0031] In some embodiments, the main body of the above raking mechanism is composed of a raking unit 200 and a lifting unit 300. Among them, the raking unit 200 is configured as the working unit of the raking mechanism, that is, the raking unit 200 has a rake body 206 that directly contacts the materials and loosens the materials subsequently. The lifting unit 300 is configured to be able to adjust the position height of the raking mechanism to adapt to the change of the material stack height. Specifically, refer to Figure 3, the above-mentioned turning and raking unit 200 includes a frame structure 201 and a rake body 206 structure. In some embodiments, the frame structure 201 includes first brackets 202 extending along two first directions and spaced apart in the second direction, and two second brackets 203 extending along the second direction and spaced apart in the first direction, wherein the first direction and the second direction are perpendicular. Exemplarily, the first direction is configured as the width direction of the box member 100, and the second direction is configured as the length direction of the box member 100. And both ends of a single second bracket 203 are respectively fixedly connected to the two first brackets 202 by means of welding or the like, that is, a rectangular interval is jointly enclosed by the two first brackets 202 and the two second brackets 203. Further, both ends of the first bracket 202 have extension segments 202a extending outside the rectangular interval in the first direction. Correspondingly, the frame structure 201 is configured as an "H"-shaped frame. Back to Figure 3 , the above-mentioned rake body 206 structure includes a plurality of acting units 204 spaced apart in the second direction. A single acting unit 204 includes a shaft body 205 extending along the first direction and a rake body 206 assembled on the shaft body 205. At the same time, both ends of the shaft body 205 of a single acting unit 204 are respectively rotatably assembled to the two second brackets 203. When the shaft body 205 rotates, the rake body 206 on the shaft body 205 contacts the material to loosen it. Further, the shaft bodies 205 of the above-mentioned plurality of acting units 204 can rotate under the action of the same driving component. In some embodiments, the above-mentioned turning and raking unit 200 further includes a power structure, and the power structure includes a motor and a transmission unit. Exemplarily, the transmission unit is configured as a chain transmission unit. At this time, a sprocket 207 is arranged on the output shaft of the motor and one end of the shaft body 205 of the acting unit 204. The plurality of sprockets 207 are connected by a chain (not shown) to achieve transmission.

[0032] Refer to Figure 2, The main body of the above-mentioned lifting unit 300 is composed of a connecting rope body and a lifting structure. In some embodiments, the lifting structure includes a driving structure (not shown), a winding cylinder 303, and a supporting pulley 304. The driving structure is fixed on the top surface of the box member 100 and includes a motor and a speed reducer structure. The winding cylinder 303 is connected to the output end of the driving structure (such as the output shaft of the speed reducer) and is configured to be able to rotate under the action of the driving structure to realize the winding and releasing of the connecting rope body. The supporting pulley 304 is configured as a fixed pulley and is installed at the top end of the box member 100. In some embodiments, the above-mentioned connecting rope body includes a first rope body part 301 and a second rope body part 302. One end of the first rope body part 301 (hereinafter referred to as the fixed end 301a) is wound around the above-mentioned winding cylinder 303, and the other end (hereinafter referred to as the free end 301b) extends vertically downward into the box member 100 after passing around the supporting pulley 304. The second rope body part 302 is configured as a connecting rope between the free end 301b of the first rope body part 301 and the frame structure 201. Exemplarily, the second rope body part 302 includes four section units 302a. One end of a single section unit 302a is connected to one end of the first bracket 202, and the other end is connected to the free end 301b of the first rope body part 301. When the lifting unit 300 operates, the winding cylinder 303 rotates under the action of the driving structure, and the first rope body part 301 is wound or released along with the rotation of the winding cylinder 303, that is, the free end 301b of the first rope body part 301 moves up and down in the vertical direction along with the rotation of the winding cylinder 303, thereby driving the frame structure 201 and the turning rake unit 200 to move up and down as a whole.

[0033] In some embodiments, slide rails (not shown) that extend vertically and allow a part of the extension section 202a of the first bracket 202 to slide are provided on the front and rear side walls of the above-mentioned box member 100. Based on the limiting effect of the slide rails, the stability of the overall movement of the frame structure 201 and the turning rake unit 200 can be improved.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention.
