However, in the actual use process of the scrap steel recycling machine, at least the following 3 defects exist, and the scrap steel recycling machine is also the technical problem to be solved by the utility model:

when the first baffle plate is pulled out, the scrap steel material can be clamped by a large force, so that the resistance of the pulling-out action is large, and the whole discharging action efficiency is low;

secondly, when the observation window structure is used, the first baffle plate is required to be pulled open slightly so as to discharge a small part of scrap steel materials, so that the size of the materials can be checked, and the first baffle plate is difficult to pull at the moment;

thirdly, the recycling bin structure lacks a drainage function, and the inclined plate can guide and receive all water bodies accidentally contained in the scrap steel materials downwards, so that the first crushing shaft and the second crushing shaft in the recycling bin are easy to rust.

Therefore, in view of the above, there is an urgent need for an anti-rust crushing apparatus that is relatively easy in both the discharging operation and the crushing degree checking operation, so as to be used in the recovery process of various scrap steel materials.

Detailed Description

The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.

As shown in fig. 1 to 9, a crushing apparatus for recovering scrap steel is structured to include a vertical upper cylinder 11, an upper crushing roller 12, and a lower crushing roller 13, and is characterized in that: the vertical upper cylinder body 11 is provided with a lower breaking roller 13, a transverse opening cylinder unit 1 for discharging water downwards and discharging materials, 2 rotary guide plate units 2 arranged on the transverse opening cylinder unit 1 and below the lower breaking roller 13 and used for supporting scrap steel materials a, and 2 sliding plate units 3 arranged in the transverse opening cylinder unit 1 and respectively positioned at two sides of the rotary guide plate units 2 and used for pushing the rotary guide plate units 2.

In this embodiment, the method of using the crushing apparatus is as follows in order.

The first sliding plate unit 3 and the second sliding plate unit 3 are both pushed inwards, firstly touch the rotary material guiding plate unit 2, and then continue to advance until the 2 rotary material guiding plate units 2 are mutually propped.

At this time, a "closed crushing chamber" for the scrap material has been formed, and for the waste water, between 2 of the rotary stock guide units 2, between the rotary stock guide units 2 and the sliding plate unit 3, and between the lateral walls of the lateral opening cylinder unit 1 can leak water downward, eventually ensuring that at least the lower crushing roller 13 is not easily rusted.

And the second, said upper crushing roller 12 and lower crushing roller 13 are opened, the former pulverizes the scrap steel singly and largely, the latter pulverizes the scrap steel continuously and complementarily, ensuring that the size of the scrap steel material in the pulverizing cavity is small enough.

Thirdly, during the period, the single sliding plate unit 3 withdraws outwards for a certain distance by a small margin, the corresponding torsion on the rotary stock guide unit 2 can rotate upwards by the same small margin, so that a small opening is exposed between the 2 rotary stock guide units 2, a small amount of scrap steel materials fall off, at the moment, whether the crushing degree of the scrap steel materials reaches the standard can be observed, and then the crushing is continued, or the upper crushing roller 12 and the lower crushing roller 13 are stopped and then the materials are discharged.

The fourth and the 2 sliding plate units 3 are largely withdrawn outwards until the upward rotation of the rotary stock guide unit 2 is blocked by the transverse opening cylinder unit 1.

At this time, the materials can fall between the 2 rotary material guide plate units 2 and the transverse opening cylinder unit 1, so that the complete one-time crushing operation can be smoothly ended.

The transverse opening cylinder unit 1 comprises a transverse rectangular cylinder 101, a feeding hole 102 arranged on the top plate of the transverse rectangular cylinder 101, a mounting hole 103 arranged on the bottom plate of the transverse rectangular cylinder 101 and used for inserting two rotary guide plate units 2, and 2 discharging holes 104 respectively arranged at two symmetrical side edge positions of the mounting hole 103.

In this embodiment, the long side direction of the inlet 102 is the length direction of the horizontal rectangular cylinder 101 and is also the sliding direction of the sliding plate unit 3, and the 2 outlet 104 are respectively disposed on two sides of the horizontal rectangular cylinder 101 in the length direction.

The width of the mounting opening 103 may be smaller than or equal to the width of the bottom plate of the horizontal rectangular cylinder 101.

Finally, the end point of the upward rotation opening of the rotary guide plate unit 2 is the broadside against the mounting opening 103, and the discharge opening 104 is narrower than the mounting opening 103, so that the rotary guide plate unit 2 does not enter the mounting opening 103.

In other words, the outlet 104 is normally open, but if it is in use, the sliding plate unit 3 slides outwards until it enters or passes the outlet 104, at which point the outlet 104 can not effectively be discharged downwards, depending on the sliding plate unit 3.

The rotary stock guide unit 2 comprises a vertical side plate 201 arranged on the transverse rectangular cylinder 101, a fixed shaft 202 arranged on the vertical side plate 201, an inclined stock guide 203 arranged in the mounting opening 103, and a mounting hole 204 arranged on the inclined stock guide 203 and used for inserting the fixed shaft 202.

In this embodiment, the inclined guide plates 203 are inclined all the time, and the inclined guide plates 203 have relatively small inclination amplitude when the crushing device is used for rotary crushing, and 2 inclined guide plates 203 are abutted against each other for bearing the scrap steel material a.

And when this crushing equipment discharges after the crushing is accomplished, the slope range of slope stock guide 203 is great relatively, and 2 slope stock guide 203 separates each other, finally obtains 3 ejection of compact positions, namely:

2 notches between the inclined guide plates 203, and 2 discharge ports 104.

The rotary stock guide unit 2 further comprises a torsion spring 205 which is sleeved on the fixed shaft 202 and is positioned in the mounting hole 204 and used for pressing the inclined stock guide 203 against the side edge of the mounting hole 103.

In this embodiment, one end of the torsion spring 205 is inserted on the fixed shaft 202, and the other end is inserted on the inner ring surface of the mounting hole 204, so as to ensure that the basic function of driving the inclined guide plate 203 to rotate by torsion is effective.

Wherein, the torsion force of the torsion spring 205 is relatively large, so that after the sliding plate unit 3 is withdrawn outwards, the torsion spring 205 drives the inclined guide plate 203 to rotate upwards until the inclined guide plate 203 abuts against the side edge of the mounting hole 103 in the length direction, namely: the weight of the scrap material a must not be excessive.

The rotary stock guide unit 2 further comprises a material size viewing port 206 provided on the vertical side plate 201.

In this embodiment, when the material size observation port 206 is used, the sliding plate unit 3 on one side is retracted slightly outwards, so as to ensure that the upper end sides of the inclined guide plates 203 originally abutted against each other are separated, and an opening is reserved.

Of course, the opening width needs to be significantly larger than the preset scrap size, otherwise the size observation operation is not meaningful.

On the other hand, if the material size observation port 206 is not available for observation, the falling sample material b for observation can be received by a basin directly below the mounting port 103, which is also convenient.

The two ends of the fixed shaft 202 are respectively arranged on the two vertical side plates 201.

In this embodiment, 1 rotary guide plate unit 2 corresponds to 1 vertical side plate 201 and 1 fixed shaft 202.

Wherein a total of 2 vertical side plates 201 are respectively positioned on the left and right sides of the mounting opening 103. Therefore, by fixedly connecting the two ends of the fixing shaft 202, the stability of the installation structure of the 2 rotary guide plate units 2 can be improved, and at least the fixing shaft 202 is not easy to break.

The sliding plate unit 3 includes a lateral sliding plate 301 provided on the inner side surface of the lateral rectangular cylinder 101 for pushing the upper surface of the inclined guide plate 203.

In this embodiment, in the whole crushing process of the crushing apparatus, the deepest and innermost positions of the sliding plates 301 that slide inward are positions where the upper end edges of the 2 inclined guide plates 203 abut against each other.

Further, since the height of the lower crushing roller 13 is relatively much higher than 2 inclined guide plates 203, in principle, the 2 horizontal sliding plates 301 need not slide synchronously, i.e., the upper end edges of the 2 inclined guide plates 203 abutting against each other need not necessarily be located directly under the centers of the 2 lower crushing rollers 13.

Also to be described is: the lower crushing roller 13 is crushed in the same manner as the upper crushing roller 12, and only when the scrap steel material falls through, the crushing operation is performed, and the material is not stirred in the crushing cavity. Therefore, when the size of the crushed material is observed to be relatively large, the rotation speed of the lower crushing roller 13 needs to be increased.

The reason why the crushing apparatus is provided with the rotary stock guide units 2 is that there is no site condition of continuous blanking every crushing operation, and moreover the sliding plate units 3 are sufficiently withdrawn outward, and the 2 rotary stock guide units 2 are separated, and the crushing apparatus is also in a state of continuous blanking.

The sliding plate unit 3 further comprises an L-shaped rod 302 arranged on the inner side surface of the transverse rectangular cylinder 101, a limiting pipe 303 arranged on the transverse sliding plate 301 and sleeved with the L-shaped rod 302, and a pushing cylinder 304 arranged on the L-shaped rod 302 and connected with the transverse sliding plate 301.

In this embodiment, the limiting pipe 303 and the cylinder shaft of the pushing cylinder 304 are fixedly connected to the outward side of the lateral sliding plate 301.

The L-shaped rods 302 are provided on the inner top surface and the vertically inner side surface of the lateral rectangular cylinder 101.

In this embodiment, no absolute leakage is possible between the lateral sliding plate 301 and the inner side of the lateral rectangular cylinder 101, so that the unexpected leakage c is formed by accumulation of the lateral sliding plate 301 over time.

At this time, the L-shaped rod 302 and the pushing cylinder 304 are not arranged on the inner bottom surface of the transverse rectangular cylinder body 101, so that the accidental leakage material c can be conveniently swept out, and the efficiency is very high.

The inclined guide plate 203 and the lateral sliding plate 301 are provided with elastic sealing rods 4 on the inner side of the lateral rectangular cylinder 101.

In this embodiment, if the opposite relatively tight seams are formed between the inclined guide plate 203, the lateral sliding plate 301 and the inner side surface of the lateral sliding plate 301, the seams are easily blocked by broken scrap steel, so that the inclined guide plate 203 cannot rotate and the lateral sliding plate 301 cannot slide, which is to be avoided.

In contrast, if the gap is too large, a large amount of scrap steel crushed material leaks from the gap, which is inconvenient for material collection operation, and thus needs to be avoided.

Therefore, in this embodiment, a row of short bars made of common rubber, that is, the elastic sealing bars 4, are disposed on the upper half portion of the two sides of the inclined guide plate 203 and one circle of the horizontal sliding plate 301, so that it is ensured that a large amount of material leakage is not easy to occur at the position, and the accidentally entered scrap is not blocked.

In other words, the elastic sealing rod 4 gives the transversal sliding plate 301 and the inclined guide plate 203 a "blurred, flexible" boundary.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
