[0040] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0041] As shown in Figure 1 、 2 and 6, the transmission device for destroying solid media of the present invention includes a frame body 1, the top of the frame body 1 is fixedly connected with a first destruction mechanism 2, a second destruction mechanism 25 and a third destruction mechanism 26, the frame body 1 is provided with a first waste bin 21, a second waste bin 251 and a third waste bin 261, and the discharge ports of the first destruction mechanism 2, the second destruction mechanism 25 and the third destruction mechanism 26 are respectively arranged corresponding to the first waste bin 21, the second waste bin 251 and the third waste bin 261 for receiving different storage media (not shown in the figure) that have been crushed.

[0042] As shown Figure 3 in FIG. 1, the first destruction mechanism 2 includes a first housing 22 which is rectangular in shape and has an accommodation cavity inside. A long strip-shaped first feed port 221 is provided at the top of the first housing 22 for putting in the first storage medium. Two long cylindrical first cutter rollers 23 which are meshed are provided in the upper part inside the first housing 22. The two first cutter rollers 23 are arranged corresponding to the first feed port 221 and are used for performing the first crushing on the first storage medium. Two long cylindrical second cutter rollers 24 which are meshed are provided in the lower part inside the first housing 22. The second cutter rollers 24 and the first cutter rollers 23 are arranged corresponding to each other and are used for performing the second crushing on the first storage medium after the first crushing to form first primary particles. Further, the circumferential wall of the first cutter roller 23 is provided with first convex teeth, and the circumferential wall of the second cutter roller 24 is provided with second convex teeth. The size of the first convex teeth is larger than that of the second convex teeth, so as to perform step-by-step refinement crushing on the first storage medium and avoid equipment jamming. Further, the cross-sectional area of the first primary particles is A, and A is less than 40 mm² (that is, 2 mm × 20 mm). It should be noted that the first storage medium is a paper material.

[0043] As shown Figure 3 in FIGS. 2 5 and 3, a flat plate-shaped connecting plate 5 is fixedly connected to the bottom of the first housing 22. The connecting plate 5 is provided with an inclined first discharge chute 51 which extends obliquely downward from the middle area to the end, so that the first storage medium after the second crushing slides down along the first discharge chute 51 to the third cutter roller 32 which will be described below.

[0044] As shown Figure 3 in FIGS. 3 7 and 4, a second housing 3 is fixedly connected to the lower end of the connecting plate 5. The second housing 3 is rectangular in shape and has an accommodation cavity inside. The bottom of the second housing 3 is fixedly connected to the frame body 1. A long cylindrical magnetic roller 31 which has magnetism is provided in the upper part near the end inside the second housing 3. The magnetic roller 31 is arranged corresponding to the first discharge chute 51. The magnetic roller 31 rotates to adsorb iron impurities such as staples in the crushed first storage medium. Further, in Figure 3 the state shown in FIG. 4, the magnetic roller 31 rotates counterclockwise to bring the crushed first storage medium falling from the first discharge channel between the two third cutter rollers 32 which will be described below. Still further, a plurality of long strip-shaped inclined storage grooves 311 are arranged along the axial direction of the magnetic roller 31 for storing the adsorbed iron impurities and can also block the primary crushed particles, making it easier to slide into the space between the two third cutter rollers 32.

[0045] As shown Figure 3As shown, two long strip-shaped third cutter rollers 32 that mesh with each other are provided in the middle of the second housing 3. The meshing part of the two third cutter rollers 32 is arranged corresponding to the magnetic roller 31, and is used to receive the first storage medium that has been secondarily crushed by the rotation of the magnetic roller 31, and then perform a third crushing on the first storage medium to form first-stage particles. Further, the third cutter roller 32 is provided with third convex teeth around its circumferential wall. The size of the second convex teeth is larger than that of the third convex teeth, so as to further finely crush the first storage medium. The cross-sectional area of the first-stage particles is B, and B is less than 6 mm² (that is, 1 mm 6 mm).

[0046] As Figure 3 shown, two long strip-shaped fourth cutter rollers 33 that mesh with each other are provided in the lower part of the second housing 3. The two fourth cutter rollers 33 are arranged corresponding to the two third cutter rollers 32, and are used to perform a fourth crushing on the first storage medium that has been thirdly crushed to form first final particles. Further, the fourth cutter roller 33 is provided with fourth convex teeth around its circumferential wall. The size of the third convex teeth is larger than that of the fourth convex teeth, so as to further finely crush the first storage medium. Further, the thickness of the fourth convex teeth is H, and H is less than 1 mm. The cross-sectional area of the first final particles is C, and C is less than 2 mm² (that is, 1 mm 2 mm).

[0047] As Figure 2 shown, the first waste bin 21 is located in the lower part of the frame body 1. The first waste bin 21 is arranged corresponding to the two fourth cutter rollers 33, and is used to collect the first final particles that have been crushed by the fourth cutter rollers 33.

[0048] Compared with the prior art, the present invention adopts the cooperative structure of the first cutter roller 23, the second cutter roller 24, the third cutter roller 32 and the fourth cutter roller 33 to gradually and finely crush the first storage medium. The crushed particles are uniform, can be continuously crushed for a long time, and are not easily jammed. In addition, by adopting the cooperative structure of the magnetic roller 31 and the first discharge chute 51, the magnetic roller 31 adsorbs and separates iron impurities, protects the cutter rollers in the second housing 3, avoids the cutter teeth of the cutter rollers in the second housing 3 from breaking, and can also avoid mixing with the crushed particles of the first storage medium, and classifies and stores them.

[0049] As another embodiment of the first discharge chute 51, the upper end of the first discharge chute 51 is hinged to the connecting plate 5. An upper portion inside the second housing 3 is provided with a rotating member which is strip-shaped and has a triangular cross-section. Of course, it can also be quadrilateral. The rotating member is located below the end of the first discharge chute 51 close to the magnetic roller 31. The rotation of the rotating member causes the first discharge chute 51 to vibrate up and down, so that the primary crushed particles on the first discharge chute 51 fall more evenly onto the magnetic roller 31, making it easier for the magnetic roller 31 to adsorb iron impurities.
