[0001] The utility model relates to the field of concrete recycling, in particular to a crusher for concrete recycling. Background Art

[0002] In the process of rapid urban development, some old and dilapidated buildings are usually demolished, and the concrete structures after demolition are usually crushed and recycled.

[0003] The Chinese utility model patent with publication number CN206631283U discloses a concrete recycling machine, including a cylindrical barrel, the barrel is provided with an inlet and a discharge port penetrating the barrel, the end surface of the barrel is provided with a sand outlet, a screw for conveying concrete is provided in the barrel, the barrel is provided with a driving motor for driving the screw to rotate, the barrel is provided with a screen that seals the screw and is fixedly connected to the screw, a plurality of nozzles for spraying carbon dioxide are provided on the inner wall of the barrel, a feeding device for conveying concrete into the barrel is provided at the inlet, and a discharging device is provided at the discharge port.

[0004] The above disclosed concrete recycling machine uses a paddle fixed on a screw to hit concrete to crush the concrete. In actual use, the farther the position on the paddle is from the screw, the faster the speed, so the crushing efficiency of hitting the concrete is better. However, the paddles currently on the market will not deliberately increase the area of ​​the end away from the screw, so that the contact area between the position where the paddle has a good crushing efficiency and the concrete is insufficient, resulting in unsatisfactory crushing efficiency. Utility Model Content

[0005] The utility model aims to provide a concrete recycling crusher, which has the advantage of improving crushing efficiency.

[0006] To achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a crusher for concrete recycling, comprising a shell, a rotating shaft built into the shell, and a rotating drive member driving the rotating shaft to rotate, and also comprising: a connecting member fixed to the rotating shaft and extending in a direction away from the rotating shaft; a crushing plate fixed to one end of the connecting member away from the rotating shaft; and at least two sections of disturbance plates fixed to the rotating shaft and located between the rotating shaft and the crushing plate along the radial direction of the rotating shaft, the disturbance plates being spiral, and the spiral directions of two adjacent sections of the disturbance plates being opposite; a plurality of the crushing plates being staggered, and two crushing plates mounted on a pair of connecting members and two adjacent crushing plates being arranged at an angle.

[0007] Through the above technical scheme, concrete is placed in the shell during crushing, and the rotating drive member drives the rotating shaft to rotate. During the rotation of the rotating shaft, the crushing plate hits the concrete block to break the concrete block. Since the crushing plate is arranged at a position away from the rotating shaft, when the speed at which the rotating drive member drives the rotating shaft to rotate is equal and the area of ​​the crushing plate is the same, the crushing plate can have a larger average speed, thereby enhancing the crushing efficiency. The spirally arranged disturbance plate can swing the concrete in a direction away from the rotating shaft, that is, toward the position where the crushing plate is located, during rotation, thereby increasing the frequency of contact between the concrete and the crushing plate and further improving the crushing efficiency. The opposite spiral direction of the disturbance plate can avoid the threaded disturbance plate driving the concrete to accumulate on one side of the shell, thereby making the concrete fully contact with the crushing plate and improving the crushing efficiency.

[0008] In one embodiment of the utility model, a plurality of connecting members are provided, the crushing plates are provided in one-to-one correspondence with the connecting members, and the connecting members are arranged in a distributed manner on the rotating shaft so that the center of gravity of the plurality of connecting members and the plurality of crushing plates is located on the axis of the rotating shaft.

[0009] Through the above technical solution, the collision frequency between the concrete and the crushing plate is increased, the crushing efficiency is further improved, and the stability of the rotation of the rotating shaft is ensured.

[0010] In an embodiment of the present invention, a plurality of pairs of the connecting members are arranged in pairs on the rotating shaft at intervals, and each pair of the connecting members is symmetrically arranged along the axis of the rotating shaft.

[0011] Through the above technical solution, the stability of the rotation of the rotating shaft is guaranteed.

[0012] In an embodiment of the present invention, two adjacent pairs of the connecting members are distributed at an angle along the circumference of the rotating shaft.

[0013] Through the above technical solution, interference between adjacent crushing plates can be avoided, and the installation density of crushing plates and connecting parts can be increased, so that more crushing plates can be installed on a rotating shaft of fixed length, the collision frequency between concrete and crushing plates can be further increased, and the crushing efficiency can be improved.

[0014] In an embodiment of the present invention, it further includes reinforcing ribs respectively fixedly connected to the rotating shaft and the connecting member.

[0015] By means of the above technical solution, the strength of the connecting piece is enhanced.

[0016] As described above, the concrete recycling crusher of the utility model has the following beneficial effects:

[0017] When crushing, concrete is placed in the shell, and the rotating drive member drives the rotating shaft to rotate. During the rotation of the rotating shaft, the crushing plate hits the concrete block to break the concrete block. Since the crushing plate is arranged at a position away from the rotating shaft, when the speed at which the rotating drive member drives the rotating shaft to rotate is equal and the area of ​​the crushing plate is the same, the crushing plate can have a larger average speed, thereby enhancing the crushing efficiency. The spirally arranged disturbance plate can swing the concrete in a direction away from the rotating shaft, that is, toward the position where the crushing plate is located, during rotation, thereby increasing the frequency of contact between the concrete and the crushing plate and further improving the crushing efficiency. The opposite spiral direction of the disturbance plate can prevent the threaded disturbance plate from driving the concrete to accumulate on one side of the shell, thereby allowing the concrete to fully contact with the crushing plate and improving the crushing efficiency.

[0022] The following specific embodiments illustrate the implementation of the present invention, and those familiar with the technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] See also Figure 1 The utility model provides a concrete recycling crusher, comprising:

[0024] A housing 1, a rotating shaft 2 built into the housing 1, both ends of the rotating shaft 2 are rotatably connected to the housing 1 through bearings, and a rotating driving member 3 driving the rotating shaft 2 to rotate, the rotating driving member 3 is configured as a motor, the housing of the motor is fixed to the housing 1 by screws, and the output shaft is transmission-connected to the rotating shaft 2.

[0025] See also Figure 2, and also includes a connecting member 4 fixed on the rotating shaft 2 and extending in a direction away from the rotating shaft 2. In this embodiment, the connecting member 4 is configured as a connecting rod, and the axial direction of the connecting rod is configured perpendicular to the axial direction of the rotating shaft 2. One end of the connecting rod is welded and fixed to the rotating shaft 2, and a crushing plate 5 is welded and fixed to the end of the connecting rod away from the rotating shaft 2. In this embodiment, multiple pairs of connecting members 4 are arranged on the rotating shaft 2 in pairs, and each pair of connecting members 4 is symmetrically arranged along the axis of the rotating shaft 2, so that the center of gravity of the multiple connecting members 4 and the multiple crushing plates 5 is located on the axis of the rotating shaft 2, so that the rotating shaft 2 rotates stably. In other embodiments, multiple connecting members 4 can be dispersedly arranged at any position on the rotating shaft 2, but it is necessary to satisfy that the overall center of gravity is located on the axis of the rotating shaft 2, and the crushing plates 5 correspond to the connecting members 4 one by one; two adjacent pairs of connecting members 4 are distributed at an angle in the circumferential direction of the rotating shaft 2. In this embodiment, two adjacent pairs of connecting members 4 are arranged at an angle of ninety degrees along the axis on the rotating shaft 2 to avoid interference between adjacent crushing plates 5, which can increase the installation density of the crushing plates 5 and the connecting members 4, thereby installing more crushing plates 5 on the rotating shaft 2 of a fixed length, further increasing the collision frequency between the concrete and the crushing plates 5, and improving the crushing efficiency.

[0026] See also Figure 2 The multiple crushing plates 5 are staggered, that is, two crushing plates 5 installed on a pair of connecting members 4 and two adjacent crushing plates 5 are arranged at an angle, so that the concrete is hit in different directions when colliding with the multiple crushing plates 5, increasing the probability of the concrete being hit and broken, and further improving the crushing efficiency.

[0027] See also Figure 2 , and also includes reinforcing ribs 7 welded and fixed to the rotating shaft 2 and the connecting member 4 respectively. In this embodiment, four reinforcing ribs 7 are fixed to each connecting member 4, and adjacent reinforcing ribs 7 are arranged at a 90-degree interval. The reinforcing ribs 7 are used to enhance the mechanical strength of the connecting member 4 to prevent the crushing plate 5 from being broken due to excessive force when colliding with concrete, thereby extending the service life.

[0028] See also Figure 2 , and also includes at least two sections of disturbance plates 6 welded and fixed on the rotating shaft 2 and located between the rotating shaft 2 and the crushing plate 5 along the radial direction of the rotating shaft 2. The disturbance plates 6 are spiral, and the spiral directions of two adjacent sections of the disturbance plates 6 are opposite. Therefore, the diffusion effect of the disturbance plates 6 when rotating is utilized to diffuse the concrete blocks in the direction away from the rotating shaft 2, that is, diffuse toward the position where the crushing plates 5 are located, thereby increasing the frequency of contact between the concrete and the crushing plates 5 and further improving the crushing efficiency.

[0029] During crushing, the utility model puts concrete into the shell 1, and the rotary drive member 3 drives the rotary shaft 2 to rotate. During the rotation of the rotary shaft 2, the crushing plate 5 hits the concrete block to crush the concrete block. Since the crushing plate 5 is arranged at a position away from the rotary shaft 2, when the rotary drive member 3 drives the rotary shaft 2 to rotate at the same speed and the crushing plate 5 has the same area, the crushing plate 5 can have a larger average speed, thereby enhancing the crushing efficiency. The spirally arranged disturbance plate 6 can swing the concrete in a direction away from the rotary shaft 2, that is, toward the position where the crushing plate 5 is located, during rotation, thereby increasing the frequency of contact between the concrete and the crushing plate 5 and further improving the crushing efficiency. The opposite spiral directions of the disturbance plate 6 can prevent the threaded disturbance plate 6 from driving the concrete to accumulate on one side of the shell 1, thereby making the concrete fully contact with the crushing plate 5 and improving the crushing efficiency.

[0030] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
