DETAILED DESCRIPTION

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0018] like Figure 1-3 As shown, a concrete slab blank cutting mechanism comprises a main body 1, a driving assembly is installed at the rear side of the main body 1, screws 2 are arranged on both sides of the main body 1, and one end of the screws 2 is connected to the driving assembly. A door frame 3 is arranged on the top of the main body 1, and the two sides of the bottom of the door frame 3 are slidably connected to the screws 2 located on both sides of the main body 1.

[0019] A blocking cover 4 is installed on the upper side of the door frame 3, and a cutting device 5 is installed inside the blocking cover 4. Connecting frames 6 are arranged on both sides of the door frame 3, and a dust box 7 is installed on the top of the door frame 3. An exhaust fan 8 is connected to one side of the dust box 7, and both sides of the dust box 7 are connected to the connecting frames 6 located on both sides of the blocking cover 4 through a three-way pipe. A first filter plate 9 is arranged on the top of the main body 1, and the interior of the main body 1 is set to be hollow. A second filter plate 10 is arranged inside the main body 1, and one end of the second filter plate 10 is slidably connected to the inner wall of the main body 1.

[0020] The driving assembly is mainly composed of an assembly bin 11 , a driving motor 12 , two synchronous wheels 13 and a synchronous belt 14 .

[0021] The assembly bin 11 is installed on the rear side of the main body 1 , the drive motor 12 is installed on the rear side of the assembly bin 11 , one end of the lead screw 2 passes through the assembly bin 11 and is connected to the synchronous wheel 13 , the two synchronous wheels 13 are connected by a synchronous belt 14 , and the drive end of the drive motor 12 passes through the assembly bin 11 and is connected to the synchronous wheel 13 .

[0022] The upper side of the main body 1 and the first filter plate 9 are concave as a whole. When cutting the concrete plate blank, the concrete plate blank can be placed on the top of the first filter plate 9, and then the motor 12 is driven to operate. Through the cooperation of the synchronous wheel 13, the synchronous belt 14 and the lead screw 2, the door frame 3 and the cutting device 5 at the bottom of the door frame 3 can be driven to move, so as to cut the concrete plate blank located on the top of the first filter plate 9. Cutting will also generate a lot of dust and debris. The blocking cover 4 can prevent the two from splashing. At the same time, the exhaust fan 8 is running, and the dust can be attracted through the connecting frame 6 and the three-way pipe, and the dust can be collected through the dust bag inside the dust box 7. The connecting frame 6 is hollow inside, and a number of through holes are provided at the bottom of the connecting frame 6 to facilitate the absorption of dust.

[0023] Since the upper side of the main body 1 and the first filter plate 9 are integrally concave, the debris can be further blocked, and then the debris will be filtered through the first filter plate 9 and the second filter plate 10. A vibration motor 15 is also provided inside the guide trough 17. After the cutting operation is completed, the collection box 18 can be inserted into the front end of the main body 1, and the vibration motor 15 at the bottom of the second filter plate 10 and inside the guide trough 17 can be controlled to run, so as to quickly send the filtered waste into the collection box 18 for subsequent processing.

[0024] Since the collecting box 18 is provided with two layers, the debris on the second filter screen and the material guide trough 17 can be collected and classified, thereby increasing the convenience of subsequent processing.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
