The present application is described in further detail below with reference to figures 1-6.

Referring to fig. 1 and 2, the embodiment of the application discloses a waste concrete crusher for goaf filling, which comprises a vertically arranged casing 1, wherein a plurality of support rods 11 for supporting the casing 1 are fixedly connected to the lower surface of the casing 1, and an inner cavity 12 is arranged in the casing 1.

Referring to fig. 2 and 3, a crushing assembly 2 for crushing concrete is arranged at the top of the inner cavity 12, specifically, the crushing assembly 2 includes two rotating shafts 21 arranged in parallel to each other, two ends of the rotating shafts 21 are rotatably connected to the casing 1, the two rotating shafts 21 are arranged at equal height, a plurality of cutting knives 211 are arranged on the two rotating shafts 21, and the plane where the cutting knives 211 are located is perpendicular to the rotating shafts 21. The cutting blades 211 on the two rotating shafts 21 are arranged in a staggered manner. A driving motor 13 for driving the two rotating shafts 21 to rotate is also fixedly connected to the outer peripheral surface of the housing 1. The rotation directions of the two rotating shafts 21 are opposite, and the sides of the two rotating shafts 21 close to each other are rotated downward.

Referring to fig. 1 and 2, a feed inlet 14 is formed in the upper surface of the casing 1, and the feed inlet 14 is located right above the pulverization assembly 2. The inner cavity 12 of the housing 1 is also provided with a screen 3. A first discharge hole 15 and a second discharge hole 16 are formed in the side wall of the casing 1, the first discharge hole 15 corresponds to a chamber above the screen 3, and the second discharge hole 16 corresponds to a chamber below the screen 3. The screen cloth 3 is obliquely arranged towards the first discharge hole 15, and the bottom wall of the inner cavity 12 is obliquely arranged towards the second discharge hole 16.

When the staff smashes the concrete, at first throw the abandonment concrete through band conveyer and deliver to feed inlet 14 in, the abandonment concrete drops on crushing unit 2, and two epaxial blades of pivot 21 form the shearing force and cut the abandonment concrete into pieces, and the back drops on screen cloth 3, and screen cloth 3 sieves the concrete that accomplishes with smashing, and the abandonment concrete of different diameters is followed first discharge gate 15 and second discharge gate 16 discharges respectively.

Further, a first discharging pipe 151 is fixedly connected to the outer peripheral surface of the casing 1 at the first discharging port 15, a second discharging pipe 161 is fixedly connected to the outer peripheral surface of the casing 1 at the second discharging port 16, the directions of the discharging ports of the first discharging pipe 151 and the second discharging pipe 161 are opposite, and one end of the first discharging pipe 151 departing from the casing 1 and one end of the second discharging pipe 161 departing from the casing 1 are both inclined downwards. With the above arrangement, the material discharged from the first discharge pipe 151 and the second discharge pipe 161 can be collected more easily.

Referring to fig. 2 and 4, mounting grooves 17 have been all seted up on the peripheral casing 1 inner wall of screen cloth 3, and the peripheral equal rigid coupling of screen cloth 3 has the installing frame 31 with the mounting groove 17 adaptation, and installing frame 31 slides and connects in mounting groove 17, and installing groove 17 extends to on the casing 1 and on the lateral wall that is in relative position with first discharge gate 15 and second discharge gate 16 place lateral wall simultaneously. After screen cloth 3 used for a long time, the staff can take out screen cloth 3 from mounting groove 17 and carry out timely clearance, if the concrete of different diameters is sieved to the needs simultaneously, also can be with changing screen cloth 3 in the mounting groove 17.

Referring to fig. 4 and 5, further, an installing block 4 is fixedly connected to a side wall of the installing frame 31 outside the casing 1, a fixing ring 18 is fixedly connected to a side wall of the casing 1, the fixing ring 18 corresponds to the installing block 4 on the installing frame 31, the fixing ring 18 is located right above the installing block 4, a first hole 41 is formed in the upper surface of the installing block 4, and a second hole 42 is formed in a side wall of the installing block 4 away from the installing block. A fixing bolt 43 is threadedly coupled between the fixing ring 18 and the first hole 41. When installing frame 31 in casing 1, the staff wears to establish fixing bolt 43 in solid fixed ring 18 and first hole 41, makes installing frame 31 fixed, when the staff need be with installing frame 31 when pulling out in casing 1, the staff is at first with fixing bolt 43 follow solid fixed ring 18 and first hole 41 dismantlement get off, later in second hole 42 with fixing bolt 43 threaded connection, then through pulling fixing bolt 43 with installing frame 31 pull out can.

Referring to fig. 2 and 6, a pressure plate 5 is horizontally arranged in the inner cavity 12 right above the crushing assembly 2, a hydraulic cylinder 19 is fixedly connected to the upper surface of the machine shell 1, and a piston rod of the hydraulic cylinder 19 extends downwards into the machine shell 1 and is fixedly connected with the upper surface of the pressure plate 5. The pressing plate 5 can move downwards when concrete crushing is carried out, and the pressing plate 5 can press the concrete block falling on the crushing assembly 2 downwards, so that the concrete block is crushed by the cutting knife 211 more easily. Meanwhile, in the process that the pressing plate 5 moves downwards, materials entering the feeding port 14 may fall to the upper surface of the pressing plate 5 and then stay on the upper surface of the pressing plate 5, so that on one hand, the lifting of the pressing plate 5 is influenced, and on the other hand, the crushing of concrete is also influenced. Therefore, the upper surface of the pressing plate 5 is provided with two inclined surfaces 51 inclined from the middle to two sides, a baffle 6 is arranged right above the two inclined surfaces 51, the upper edge of the baffle 6 is hinged with the upper wall of the inner cavity 12, and the lower edge of the baffle 6 is arranged on the inclined surfaces 51 in an overlapping manner. When the pressure plate 5 moves downwards, the lower edge of the baffle 6 slides along the inclined plane 51, and when the pressure plate 5 rises, the lower edge of the pressure plate 5 slides downwards along the inclined plane 51, so that concrete on the inclined plane 51 can be pushed to the lower part of the pressure plate 5.

The implementation principle of the waste concrete pulverizer for filling the goaf is as follows: the staff delivers the abandonment concrete to feeder hopper 141 in through the belt conveyer, and the concrete piece can drop on crushing unit 2, is smashed and then drops on screen cloth 3 under the shearing force effect of cutting knife 211 on two pivot 21, and screen cloth 3 screens the concrete after smashing, then discharges the material of different diameters from first discharging pipe 151 and second discharging pipe 161. When concrete with different diameters needs to be screened, a worker first detaches the fixing bolt 43 from the fixing ring 18 and the attachment block 4, then screws the fixing bolt 43 into the second hole 42 on the attachment block 4, and then pulls out the mounting frame 31 to replace the screen mesh 3.

In the working process of the crusher, the pressing plate 5 presses the concrete above the crushing assembly 2 downwards under the action of the hydraulic cylinder 19, so that the crushing effect of the crushing assembly 2 is better, and meanwhile, the baffle 6 and the inclined surface 51 on the upper surface of the pressing plate 5 can avoid the phenomenon of material accumulation on the upper surface of the pressing plate 5 as much as possible.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
