[0023] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of the utility model proposes a grinding mechanism for asphalt for drilling fluid, including a grinding box 1, which performs preliminary grinding of asphalt, and the inner side of the grinding box 1 is rotatably connected with two symmetrically distributed crushing shafts 2, and the two crushing shafts 2 are provided with staggeredly distributed crushing blades 3, and the crushing blades 3 on the two crushing shafts 2 are staggered. When the two crushing shafts 2 rotate, the asphalt is crushed by the crushing blades 3, and a driving component 4 for controlling the rotation of the crushing shafts 2 is installed on one side of the grinding box 1 to realize the rotational drive of the two crushing shafts 2 so that the two crushing shafts 2 rotate inwardly, and a lower hopper 6 is integrally formed at the bottom of the grinding box 1, and a grinding pipe 5 is arranged at the bottom of the lower hopper 6, and the preliminary crushed asphalt enters the grinding pipe 5 through the lower hopper 6 for secondary grinding of the asphalt, and a driving component 4 for controlling the rotation of the crushing shafts 2 is installed on the inner bottom of the grinding pipe 5 for crushing the asphalt material The secondary crushing component 7 for processing is used to perform secondary crushing of asphalt to increase the fineness of asphalt crushing. The secondary crushing component 7 includes a transverse plate 701 fixedly connected to the bottom of the crushing tube 5, and a protective sleeve 702 rotatably connected to the transverse plate 701. The top of the protective sleeve 702 extends to the top of the transverse plate 701 and is fixed with forward crushing blades 708. When the protective sleeve 702 rotates, the forward crushing blades 708 are driven to rotate, and the asphalt is crushed clockwise. The inner side of the protective sleeve 702 is rotatably connected to the shaft rod 703. The top of the shaft rod 703 extends to the top of the protective sleeve 702 and is fixed with reverse crushing blades 709. When the shaft rod 703 rotates, it drives the reverse crushing blades 709 to rotate, realizing the counterclockwise crushing of the asphalt. This method can simultaneously perform forward and reverse crushing of asphalt, and quickly realize the crushing of asphalt.

[0024] like Figure 4 As shown, in some embodiments, the bottom of the shaft 703 extends to the bottom of the protective sleeve 702 and is fixed with a gear 1 704. When the gear 1 704 rotates, it can drive the shaft 703 to rotate. The protective sleeve 702 is fixedly connected with a gear 3 707 for driving the protective sleeve 702 to rotate. A motor 2 706 is installed on the lower surface of the cross plate 701. The output shaft of the motor 2 706 is fixedly connected with a gear 2 705. The gear 2 705 is meshed with the gear 1 704 and the gear 3 707 respectively. When the gear 2 705 rotates, it can simultaneously drive the gear 3 707 and the gear 1 704 to move forward and reversely, thereby realizing the forward and reverse rotation of the protective sleeve 702 and the shaft 703, driving the corresponding forward crushing blades 708 and reverse crushing blades 709 to rotate, thereby realizing the forward crushing blades 708 and reverse crushing blades 709 to rotate. Drive the rotation drive.

[0025] like Figure 4 As shown, in some embodiments, bearings are provided between the protective sleeve 702 and the cross plate 701 , and between the protective sleeve 702 and the shaft rod 703 , so as to achieve stable rotation of the protective sleeve 702 and the shaft rod 703 .

[0026] like Figure 1 and Figure 3 As shown, in some embodiments, the driving component 4 includes two supports 401 fixedly connected to one side of the crushing box 1, and a rotating rod 402 rotatably connected between the two supports 401. The rotating rod 402 can rotate stably and can drive the crushing shaft 2 to rotate when rotating. Two worms 403 are fixedly connected to the rotating rod 402. The driving shaft at the end of the crushing shaft 2 extends to the outside of the crushing box 1 and is fixed with a worm wheel 405. The worm wheel 405 is meshed with the corresponding worm 403. When the rotating rod 402 rotates, the crushing shaft 2 can be driven to rotate through the matching relationship between the worm 403 and the worm wheel 405, thereby realizing the rotation drive of the crushing shaft 2.

[0027] like Figure 1 and Figure 3 As shown, in some embodiments, a motor 404 for controlling the rotation of the rotating rod 402 is installed on the crushing box 1 to realize the rotation drive of the rotating rod 402.

[0028] The working principle and use steps of the utility model are as follows: the motor 1 404 and the motor 2 706 are driven to work, and the asphalt raw material is placed inside the crushing box 1. The motor 1 404 can drive the rotating rod 402 to rotate on the support 401. When the rotating rod 402 rotates, the worm 403 can be rotated. The corresponding crushing shaft 2 is driven to rotate through the matching relationship between the worm 403 and the worm wheel 405, so that the two crushing shafts 2 rotate in opposite directions, and then the asphalt inside the crushing box 1 is crushed by the staggered crushing blades 3. The initially crushed asphalt enters the crushing tube 5 through the lower hopper 6. Then, the asphalt is secondary crushed by the secondary crushing component 7. When the secondary crushing component 7 is working, the motor 2 706 drives the gear 2 705 to rotate, and drives the gear 3 707 and the gear 1 704 to rotate in the opposite direction, so that the protective sleeve 702 and the shaft 703 rotate relatively, and drives the corresponding forward crushing blades 708 and reverse crushing blades 709 to rotate. The forward crushing blades 708 and the reverse crushing blades 709 rotate in opposite directions, and then the asphalt is finely crushed by the forward crushing blades 708 and the reverse crushing blades 709, thereby increasing the crushing effect and facilitating the subsequent production and processing of drilling fluid.
