Technical Field
[0001] The utility model relates to the technical field of concrete surface crushing equipment, in particular to a concrete surface roughness crusher. Background Art
[0002] The surfaces of factory concrete structure columns and beams, bridge concrete structures, road concrete structures, etc. need to add a concrete structure layer. The old structure surface needs to be broken and a new layer of the same structure needs to be added to ensure good bonding between the new and old concrete structures.
[0003] In order to improve the crushing effect of the concrete surface, we propose a concrete surface roughness crusher. Utility Model Content
[0004] The purpose of the utility model is to provide a concrete surface roughness crusher to solve the problems in the prior art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete surface roughening crusher, comprising a fixed seat and a frame, a plurality of winches are installed at equal intervals on the outside of the fixed seat, and the winches are connected to the frame by ropes; a plurality of steel drill bases are installed at equal intervals on the frame, a plurality of alloy steel drills are installed on one end of the steel drill base, a cam motor for acting on the steel drill base is installed on the frame, and the steel drill base is located at one end of the cam motor and is covered with a spring.
[0006] Preferably, the steel drill base is provided with an arc-shaped groove at one end of the cam motor.
[0007] Preferably, there are four winches in total, and the four winches are evenly distributed outside the fixing seat.
[0008] Preferably, the cam motor drives a cam, and there are four cam motors in total.
[0009] Compared with the existing technology, the beneficial effects of the utility model are: the cam crusher is fixed on the frame, the cam rotates with the motor to hit the crusher slot, and a circle of spring is set under the crusher slot to ensure that the crusher can recover quickly after it fails; the main work of the crusher is to repeatedly crush the concrete surface with an alloy steel drill (the crushing depth is about 5-10mm); the crusher contact surface needs to be set according to the different concrete structure sections.

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.
[0014] See also Figure 1 In an embodiment of the present invention, a concrete surface roughness crusher includes a fixed base 2 and a frame 4. A plurality of hoists 1 are installed at equal intervals outside the fixed base 2. There are four hoists 1 in total. The four hoists 1 are evenly distributed outside the fixed base 2. The hoists 1 are connected to the frame 4 through ropes 3.
[0015] The rack 4 is equipped with multiple steel drill bases 6 at equal intervals, and multiple alloy steel drills 5 are installed at one end of the steel drill base 6. The rack 4 is equipped with a cam motor 7 that acts on the steel drill base 6. The steel drill base 6 is located at one end of the cam motor 7 and is sleeved with a spring 8. The steel drill base 6 is located at one end of the cam motor 7 and is provided with an arc-shaped groove. The cam motor 7 drives a cam, and there are four cam motors 7. A fixed winch is provided, and the winch pulls the crusher to move. The crusher frame is made according to the different cross-sections of concrete structure beams and columns. The cam crusher is fixed on the frame, and the cam rotates with the motor to hit the crusher slot.
