[0003] When existing waste concrete crushing equipment crushes waste concrete, the waste concrete is usually directly added into the equipment, and then the crushing teeth in the equipment crush the waste concrete. However, for some large blocks of waste concrete, they are directly added into the equipment for crushing, and the crushing teeth in the equipment cannot crush them quickly, and the crushing efficiency is low. In view of this, we propose a waste concrete crushing equipment. Utility Model Content

[0023] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0024] Example: A discarded concrete crushing device, see Figures 1 to 6 , including a concrete crusher 1 for crushing waste concrete, a pre-crushing structure 2 is arranged at the top feed port of the concrete crusher 1, the pre-crushing structure 2 includes a mounting cover 3 that is matched with the top feed port of the concrete crusher 1, two groups of symmetrical crushing structures 5 are slidingly arranged on both sides of the mounting cover 3, four groups of hydraulic cylinders 4 corresponding to the four corners of the crushing structure 5 are arranged on both sides of the mounting cover 3, and the piston ends of the hydraulic cylinders 4 are fixedly connected to the crushing structure 5. When crushing waste concrete, if the waste concrete is crushed into large blocks, the large blocks of waste concrete are directly crushed and added vertically from the top port of the mounting cover 3, and then the bottom of the large blocks of waste concrete falls onto the crushing roller inside the concrete crusher 1. At this time, the large blocks of waste concrete are located inside the mounting cover 3, and then the two groups of crushing structures 5 are driven by the hydraulic cylinder 4 to move relative to each other, so as to pre-crush the large blocks of waste concrete. The pre-crushed waste concrete falls into the concrete crusher 1 for secondary crushing, thereby achieving rapid crushing of large blocks of waste concrete;

[0025] Specifically, shielding protrusions 301 are arranged on both sides of the interior of the installation cover 3 above the crushing structure 5, and the top surface of the shielding protrusion 301 is tilted downward. The shielding protrusion 301 is convenient for invisible shielding of the crushing structure 5 below it, and the inclined surface facilitates the introduction of waste concrete into the interior of the installation cover 3.

[0026] Furthermore, a slide groove 302 is arranged in the front and rear of the mounting cover 3, and a slider 303 is slidably installed inside the slide groove 302. The slider 303 passes through the outer end of the slide groove 302 and is fixedly connected to the mounting plate 501. The slide groove 302 and the slider 303 cooperate to realize the horizontal sliding installation of the crushing structure 5.

[0027] In a specific embodiment, the crushing structure 5 includes a mounting plate 501 and a crushing rod 502. Several groups of crushing rods 502 are arranged on the side of the mounting plate 501 facing away from the corresponding hydraulic cylinder 4, and the front end of the crushing rod 502 is conical. The crushing rods 502 on the mounting plate 501 are distributed in a field shape, and the crushing rods 502 on the two groups of mounting plates 501 are staggered. When the two groups of crushing structures 5 pre-crush large blocks of waste concrete, the large blocks of waste concrete can be directly crushed into multiple small blocks of waste concrete of equal size, so that the crushing structure 5 can pre-crush the large blocks of waste concrete more evenly and the crushing effect is better.

[0028] Specifically, four groups of equidistant protrusions 503 are arranged around the pounding rod 502, and the protrusions 503 are in the shape of triangular pyramids. As the pounding rod 502 is inserted into the waste concrete, the triangular pyramid protrusions 503 thereon can quickly crush and split the waste concrete.

[0029] Furthermore, baffles 6 are arranged on both sides of the interior of the mounting cover 3, and the side surfaces of the baffles 6 are aligned with the bottom sides of the corresponding shielding protrusions 301, and the baffles 6 cover the pounding rods 502 on the corresponding pounding structure 5. The baffles 6 have a shielding and protective effect on the pounding structure 5, preventing the waste concrete from touching the pounding rods 502 and being unable to fall smoothly, and also preventing the crushed waste concrete from being stuck between the pounding rods 502.

[0030] Furthermore, a plurality of through holes 601 are arranged on the surface of the baffle 6 , and the size of the through holes 601 matches the outer diameter size surrounded by the plurality of ridges 503 . The through holes 601 facilitate the passage of the pounding rod 502 with the ridges 503 .

[0031] It is worth noting that a reinforcement structure 504 is arranged on the side of the mounting plate 501 facing away from the masher rod 502. The reinforcement structure 504 is formed by a staggered combination of several groups of transverse ribs and vertical ribs. The reinforcement structure 504 is used to reinforce the mounting plate 501, improve the strength of the mounting plate 501, and effectively prevent its deformation. The utility model solves the technical problem of low efficiency of current waste concrete crushing equipment in crushing large blocks of waste concrete through the pre-crushing structure 2.

[0032] Working principle: When crushing waste concrete, if the waste concrete is crushed into large blocks, the large blocks of waste concrete are directly added vertically from the top of the installation cover 3, and then the bottom of the large blocks of waste concrete falls onto the crushing roller inside the concrete crusher 1. At this time, the large blocks of waste concrete are located inside the installation cover 3, and then the hydraulic cylinder 4 drives the two groups of crushing structures 5 to move relative to each other to pre-crush the large blocks of waste concrete. The pre-crushed waste concrete falls into the concrete crusher 1 for secondary crushing. Therefore, the large blocks of waste concrete can be quickly crushed;

[0033] Secondly, when the two groups of crushing structures 5 pre-crush large blocks of waste concrete, the crushing rods 502 distributed in a field shape on the crushing structure 5 can directly crush the large blocks of waste concrete into multiple small blocks of waste concrete of equal size, thereby making the crushing structure 5 pre-crush the large blocks of waste concrete more uniform and achieving a better crushing effect.

[0034] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
