DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Reference Figure 1-3 One embodiment of the utility model provides a scrap steel crushing device, comprising the following parts:

[0031] A box body 1 and a crushing assembly 2 arranged in the box body 1. The box body 1 is equipped with legs and can be placed on the ground. The crushing assembly 2 is used to crush the scrap steel. The box body 1 is through-set from top to bottom. The upper and lower parts can be understood as the discharge end and the discharge end respectively. The material is put in from the top and discharged from the bottom after being crushed.

[0032] A material receiving frame 3 is arranged at the material discharging end of the box body 1, and a material leakage hole 4 is arranged on the material receiving frame 3, and the aperture of the material leakage hole 4 is consistent with the size that the crushed material is required to reach in the end;

[0033] The guide assembly 5 is arranged on one side of the receiving frame 3. When the crushed materials discharged from the box body 1 fall onto the receiving frame 3, the materials that meet the size requirements will pass through the leakage holes 4 and fall to the bottom, so that they can be recycled, while the materials that do not pass through will be buffered on the receiving frame 3 and can be transported to the box body 1 under the action of the guide assembly 5, so as to continue to be crushed.

[0034] Based on the above, with the cooperation of the guiding component 5, after the crushed material is discharged from the box body 1, as long as it fails to pass through the leakage hole 4, it can be continuously put into the box body 1, so as to continuously crush the metal blocks that have not been completely crushed, and can only fall from the leakage hole 4 after being completely crushed, thereby ensuring the uniformity of the particles of the waste material finally crushed, so as to smoothly carry out the subsequent refining process.

[0035] Further, see Figure 1-3 as well as Figure 5 and Figure 7 The guide assembly 5 may be in various forms. In the present application, it includes a belt 501 that circulates along a fixed path and a push plate 502 connected to the belt 501. The push plates 502 are arranged along the length of the belt 501. The belt 501 only needs to move along a fixed path. Specifically, it may be a belt or a chain belt. The movement path of the belt 501 is relatively fixed to the box 1.

[0036] Based on this, when the belt 501 moves, all the push plates 502 move synchronously with it along the movement path of the belt 501. The path of the belt 501 can be set to pass through the material receiving frame 3 and the top of the box 1, so that the material buffered in the material receiving frame 3 is pushed onto the belt 501 under the pushing action of the push plates 502. The cooperation between the belt 501 and the push plates 502 will transport the material to the top of the box 1. When it arrives here, Figure 1 As shown, due to the change in direction of the push plate 502, the material falls from the push plate 502 into the box body 1, thereby guiding the material. This structure makes the guiding process simple and the structure is also relatively simple, so as to achieve a compact effect of the device.

[0037] Further, see Figure 1-3 as well as Figure 5-6 The present application also includes a protective cover 6 fixedly arranged relative to the movement path of the belt body 501, which is used to form a cover for the place where the push plate 502 passes, and the two ends of the protective cover 6 extend to the material receiving frame 3 and the top of the box body 1 respectively, so as to ensure that the push plate 502 is not easy to cause the material to fall off when carrying the material; through the cooperation of the protective cover 6, the movement path of the belt body 501 can be formed by installing a guide wheel 10 on the protective cover 6 and the box body 1, so that the belt body 501 is wound thereon, thereby completing the assembly of the belt body 501, and regarding the setting of the driving force of the belt body 501, the driving force can be set on the guide wheel 10, specifically, a driving motor can be set, and at least one of the guide wheels 10 can be set to cooperate with the transmission.

[0038] Further, see Figure 5 and Figure 6 Regarding the material receiving frame 3, it at least includes a bottom plate 301, the leakage hole 4 is arranged on the bottom plate 301, the bottom plate 301 is inclined, and the push plate 502 passes through the lowest level of the bottom plate 301 to one side, so that the material cached on the bottom plate 301 can better slide to the push plate 502 through the inclined cooperation of the bottom plate 301 surface, thereby ensuring that the cached material can be guided in time to reduce the occurrence of accumulation.

[0039] Further, see Figure 4 The pulverizing assembly 2 includes multiple pairs of pulverizing rollers 201, three pairs of which are shown in the figure and can be used as a reference. The multiple pairs of pulverizing rollers 201 are vertically distributed, and the rolling gap of each pair of pulverizing rollers 201 decreases from top to bottom. This design can better adapt to the crushing and rolling process, that is, during crushing, it can be broken into large pieces first, and then gradually broken into small pieces, so that the crushing effect is more thorough.

[0040] Further, see Figure 2 and 4 Regarding the power configuration of the multiple crushing rollers 201, specifically, a belt drive or gear drive can be configured between the multiple crushing rollers 201, or the method shown in the figure can be adopted, that is, a chain belt 7 is included, and a sprocket 8 is provided on each of the crushing rollers 201, and the chain belt 7 and the multiple sprockets 8 are assembled. Finally, as long as at least one of the crushing rollers 201 or the chain belt 7 is configured with a driving force, the driving of the multiple crushing rollers 201 can be achieved. The driving force here can be a motor, such as Figure 1 As shown in , the driving motor is connected to one of the crushing rollers 201 .

[0041] Further, see Figure 2 and Figure 5-6, the present application also includes an elastic connector 9 fixedly arranged relative to the box body 1, which can be an elastic iron bar or a spring, and is directly fixedly connected to the box body 1. The figure shows an elastic iron bar, which is used as a reference. The material receiving frame 3 also includes a frame body 302, and the frame body 302 and the protective cover 6 can also be fixedly connected. One end of the bottom plate 301 is movably connected to the frame body 302, and the other end is connected to the elastic connector 9. One end of the elastic connector 9 extends to the movement path of the chain belt 7;

[0042] Based on this, when the chain belt 7 moves, it can continuously touch the elastic connecting part 9 and drive the bottom plate 301 to shake, thereby promoting the qualified crushed materials to pass through the bottom plate 301 as soon as possible, and at the same time promoting the unqualified crushed materials to shake faster toward the push plate 502, so as to reduce the accumulation on the bottom plate 301 and increase the working speed of the device.

[0043] Further, see Figure 3 and Figure 6 The bottom plate 301 and the frame 302 may be hingedly connected at one end. The hinged connection has a better stabilizing effect and ensures that there is no gap at the connection between the bottom plate 301 and the frame 302, so that the material is not likely to leak.

[0044] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
