DETAILED DESCRIPTION

[0031] The two embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0032] First embodiment:

[0033] Figures 1-2 As shown, an energy-saving crushing device for producing reclaimed rubber comprises a support frame 1, two groups of driving units are fixedly installed on the bottom upper end, a crushing chamber 3 is fixedly connected to the upper end of the support frame 1, a feeding hopper 4 is fixedly connected to the upper end of the crushing chamber 3, and a discharge hopper is fixedly connected to the lower end of the crushing chamber 3; the feeding hopper 4, the crushing chamber 3, and the discharge hopper are sequentially and mutually communicated; two crushing rollers 5 that are mutually engaged are installed inside the crushing chamber 3; the ends of the two crushing rollers 5 extend outside the crushing chamber 3; the crushing rollers 5 are connected to the crushing chamber 3 through bearings at both ends and extend outside the crushing chamber 3; one end of the crushing roller 5 is fixedly connected to a connecting shaft; the connecting shaft is connected to the driving unit on the same side; the driving unit comprises a horizontal rod 201 fixedly connected to the bottom of the support frame 1, an electric motor 2 fixedly connected to the upper end of the horizontal rod 201, and a synchronous belt assembly fixedly connected between the connecting shaft and the electric motor 2; the two connecting shafts are on different sides and are centrally symmetric about the center of the crushing chamber 3; the synchronous belt assembly comprises two belt pulleys 31 fixedly connected to the connecting shaft and the output shaft of the electric motor 2, respectively, and a synchronous belt 32 that is collectively sleeved outside the two belt pulleys 31; when crushing the rubber material, the two electric motors 2 can be controlled to rotate, thereby driving the two crushing rollers 5 to rotate towards each other, thereby engaging the rubber material in the feeding hopper 4, and realizing the crushing of the rubber material.

[0034] As Figures 3-4The crushing roller 5 comprises a center shaft fixedly connected with two limiting strips at outer ends, a plurality of annular cutters 51 and a plurality of limiting rings 52 are sleeved at outer ends of the center shaft in a spaced manner, two limiting grooves are formed in each of the annular cutters 51 and the limiting rings 52, the limiting grooves are matched with the limiting strips, the outermost two limiting rings 52 are fixedly connected with the crushing roller 5 through bolts, the cutting edges of the adjacent two annular cutters 51 on the same crushing roller 5 are deviated from each other by 5-10°, and the cutting edges of the opposite two annular cutters 51 in the two crushing rollers 5 are staggered, so as to facilitate the occlusion of the rubber material.

[0035] As Figures 5-6 The feeding hopper 4 comprises a material collecting section 41 and a pre-shaking section 42 fixedly connected at a lower end of the material collecting section 41, the material collecting section 41 is made of hard metal, and the pre-shaking section 42 is made of high-strength flexible material. The feeding hopper 4 is arranged in a double-layer structure of hard and soft combination, so that the feeding hopper 4 can be in an irregular state, and the rubber material in the feeding hopper 4 can be moved unbalancedly, so that the rubber material is difficult to bridge, thereby achieving the effect of effectively breaking the arch. Compared with the prior art, the influence of the rubber material bridging on the crushing efficiency is effectively avoided, and the connection between the pre-shaking section 42 and the material collecting section 41 is not lower than the middle line of the taper surface of the material collecting section 41, so that the span of the flexible pre-shaking section 42 is not too large or too small, which can maintain the carrying capacity of the rubber material and enable the pre-shaking section 42 to present relatively large unbalanced shaking, so that the arch breaking effect is better.

[0036] The arch breaking unit is fixedly connected with an upper support ring plate 402 at an outer end of the taper surface of the material collecting section 41, a lower support ring plate 401 at an outer end of a lower edge of the pre-shaking section 42, and four electric push rods 7 fixedly connected at an upper end of the lower support ring plate 401. The four electric push rods 7 are respectively located at four corners of the lower support ring plate 401. The lower support ring plate 401 is further fixedly connected with a plurality of evenly distributed buffer strips 6. The four buffer strips 6 are respectively and spacedly distributed with the four electric push rods 7. The buffer strips 6 are made of high-resilience material, and when the pre-shaking section 42 is in a straightened state, the upper ends of the buffer strips 6 are flush with the upper end of the pre-shaking section 42. Figure 9, when in use, two electric push rods 7 can be controlled to shorten quickly, and the top of the elongated section of the electric push rod 7 is lower than the buffer strip 6, the other two electric push rods 7 are controlled to be stationary, and then the whole feeding hopper 4 is tilted to the side of the shortened electric push rod 7, when the upper supporting ring plate 402 contacts the buffer strip 6, the buffer strip 6 can be in contact with the buffer strip 6 and continue to tilt, the buffer strip 6 can effectively control the tilting speed of the electric push rod 7, so that it is not easy to lose balance and tilt completely due to rapid tilting, when the upper supporting ring plate 402 contacts the electric push rod 7 again, control two electric push rods 7 to elongate to the original length, and then along the clockwise or counterclockwise direction, take one of the electric push rods 7 as the center point, control the adjacent other electric push rod 7 and the electric push rod 7 at the center point to shorten, and repeat the above process again, so that the whole feeding hopper 4 is always in a dynamic state, and the rubber material in the feeding hopper 4 is difficult to gather at a certain angle for a long time under the unbalanced shaking of the feeding hopper 4, thereby effectively avoiding bridging and achieving the effect of breaking the arch, thereby effectively ensuring the breaking efficiency of the rubber material.

[0037] As Figure 7 , the elongated end of the electric push rod 7 is upward, and the elongated end of the electric push rod 7 is in contact with the upper supporting ring plate 402, and the outer end of the fixed section of the electric push rod 7 is fixedly connected with the upper supporting ring plate 402. The restraint flexible sleeve 71 is arranged outside the elongated section of the electric push rod 7, and the restraint flexible sleeve 71 is also made of high-strength flexible material, so that the electric push rod 7 will not completely lose contact with the feeding hopper 4 after shortening, and the restraint flexible sleeve 71 can limit the shaking range of the feeding hopper 4, so that it is not easy to tilt excessively due to the gravity of the internal rubber material.

[0038] In summary, by arranging the feeding hopper 4 in a soft and hard combination of upper and lower double layers, and cooperating with the arrangement of the arch breaking unit, the feeding hopper 4 itself can be in an unbalanced and unstable state, thereby driving the rubber material inside to move unbalancedly, making it difficult to bridge, thereby achieving the effect of effectively breaking the arch. Compared with the prior art in Figure 8 , the influence of the bridging of the rubber material on the crushing efficiency is effectively avoided.

[0039] Second embodiment:

[0040] The present embodiment is further improved on the basis of the first embodiment, and the remaining parts remain the same as the first embodiment.

[0041] Figure 10It is shown that the buffer strip 6 comprises a fixed base plate 61 and a dynamic pressure layer 62 fixedly connected to the upper end of the fixed base plate 61, the lower end of the fixed base plate 61 is provided with a long sliding groove 601, the upper end of the lower support ring plate 401 is provided with an electric sliding rail, the electric sliding rail is provided with an electromagnetic sliding block 602, the electromagnetic sliding block 602 is matched with the long sliding groove 601, the inside of the dynamic pressure layer 62 is provided with two long holes perpendicular to the vertical center line of the dynamic pressure layer 62, a plurality of pre-hard capsules 8 are placed in the long holes, the pre-hard capsules 8 are filled with magnetorheological fluid, the length of the electromagnetic sliding block 602 is greater than the length of the pre-hard capsules 8, the two sides of the long sliding groove 601 are respectively matched with the inner walls of the two long holes, when the feeding hopper 4 is tilted on one side as in the first embodiment, as Figure 11 the electric sliding rail can drive the electromagnetic sliding block 602 to move, and the electromagnetic sliding block 602 can be controlled to be electrified, when the electromagnetic sliding block 602 passes through the pre-hard capsules 8, the corresponding pre-hard capsules 8 will be hardened under the action of the magnetic field, thereby forming a temporary support point, and the support point serves as a vertex, Figure 12 at this time, the hardened pre-hard capsules 8 and the two electric push rods 7 in the original length form a non-isosceles triangle vertical support for the upper support ring plate 402, thereby causing the support force received by the feeding hopper 4 to be difficult to balance, on the one hand, it will cause the feeding hopper 4 to tilt towards the side far away from the hardened pre-hard capsules 8, thereby achieving a certain tilting deflection in the process of the overall tilting of the feeding hopper 4 on one side, making the shaking effect on the internal rubber material better, making it easier to redistribute, and difficult to locally gather and overlap to form a bridge, on the other hand, the tilting speed of the feeding hopper 4 can be limited to a certain extent, so that it is not easy to produce too fast tilting towards one direction, thereby facilitating the relative stability of the feeding hopper 4 in the unbalanced shaking state.

[0042] By setting the feeding hopper 4 as a soft and hard combination of upper and lower double layers, and cooperating with the setting of the arch breaking unit, the feeding hopper 4 itself can be in an unbalanced and unstable state, thereby driving the rubber material inside to move unbalancedly, making it difficult to form a bridge, thereby achieving the effect of effectively breaking the arch, compared with the prior art, effectively avoiding the influence of the rubber material forming a bridge on the crushing efficiency; in addition, cooperating with the effect of the buffer strip 6 which can change the hardened point, when the feeding hopper 4 is tilted unbalancedly towards one side, the support point of the buffer strip 6 on this side can change constantly, thereby forming a non-isosceles triangular three-point support with the two electric push rods 7 on the lifting side, so that the feeding hopper 4 can not only deflect the angle when tilting on one side, making the arch breaking effect better, but also can make the unbalanced shaking relatively stable, so that it is not easy to occur in the case of one-sided rapid tilting, thereby maintaining the relative stability of the feeding hopper 4 in the unbalanced shaking state, so that it is not easy to tilt excessively.

[0043] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application do not limit the protection scope, various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection scope of the present application.
