[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A filling device for mine blasting holes, comprising:

[0026] The box body 1 has a feed hopper 4 at the center of the upper end face, a crushing structure 5 at the upper center of the inside of the box body 1, a screening structure 6 at the center of the inside of the box body 1, an anti-blocking structure 7 at the lower center of the inside of the box body 1, a packing pipe 8 at the center of the lower end face of the box body 1, four support legs 9 arranged in a rectangle at the lower end face of the box body 1, a rotator 10 at the center of the lower end face of the four support legs 9, and wheels 11 at the output end of each of the four rotators 10, an observation window 2 at the center of the front end face of the box body 1, a control panel 3 at the upper center of the front end face of the box body 1, and pushers 12 at the front and rear of the upper side wall of the box body 1. The box body 1 is made of aluminum alloy.

[0027] When the device needs to be moved to different working positions, the rotators 10 on the lower end faces of the four support legs 9 drive the wheels 11 to rotate. The operator can push the pusher 12 to move the entire box 1. After reaching the working position, the rotators 10 can be used to adjust the state of the wheels 11 so that the device can be stably supported on the ground for operation. The operator can observe the condition of the material inside the box 1 at any time through the observation window 2 on the front face of the box 1, such as the amount of material and whether there are signs of blockage. At the same time, the control panel 3 can be used to start or stop the power components corresponding to each structure to ensure the normal operation of the entire packing device.

[0028] The crushing structure 5 includes four first servo motors 501, which are arranged in a front-to-back manner at the upper center of one side wall of the housing 1. The output ends of the four first servo motors 501 all penetrate through one side wall of the housing 1 and extend into the interior of the housing 1, and each end is fixedly connected to a crushing rod 502. By starting the four first servo motors 501, the crushing rod 502 is driven to rotate. When the material falls, the high-speed rotating crushing rod 502 will crush larger particles of material, making them smaller in size, which is beneficial for subsequent processing. By using the crushing rod 502, the agglomerated packing material can be made into a looser state with a suitable particle size, preventing large pieces of material from entering the subsequent structure and causing blockage problems.

[0029] The screening structure 6 includes two sliding frames 601, which are respectively located at the upper and lower center of the box body 1. A sliding box 602 is slidably connected to the center of each sliding frame 601. A filter screen 603 is installed at the center of each sliding box 602. One end of each sliding box 602 penetrates the rear inner wall of the box body 1 and extends to the rear end face of the box body 1. The crushed material falls onto the screening structure 6 and is supported by the two sliding frames 601. The filter screen 603 inside the sliding box 602 can screen the material. Fine materials that meet the particle size requirements can continue to fall through the filter screen 603, while larger particles remain inside the sliding box 602. By slidably connecting the sliding box 602 to the sliding frame 601, it is convenient for workers to remove the sliding box 602 and clean the filter screen 603. It also facilitates the handling of larger or clump-like materials remaining on the filter screen 603.

[0030] The anti-clogging structure 7 includes three second servo motors 701, which are arranged in a front-to-back manner at the lower center of one side wall of the housing 1. The output ends of the three second servo motors 701 all pass through one side wall of the housing 1 and extend into the interior of the housing 1. Each end is fixedly connected to an anti-clogging stirring rod 702. By starting the three second servo motors 701, the anti-clogging stirring rods 702 are driven to rotate. The rotating anti-clogging stirring rods 702 continuously stir the material, preventing the material from being blocked in the lower part of the housing 1 and at the inlet of the packing tube 8, thus ensuring that the material can flow smoothly into the packing tube 8.

[0031] The working principle of this utility model is as follows:

[0032] The operator pushes the housing 1 by holding the push handle 12, controls the rotation direction of the wheels 11 by the rotator 10, and moves the housing 1 by the wheels 11 to the designated mining blasting hole operation position. After reaching the position, the angle and state of the wheels 11 can be adjusted again by the rotator 10 to ensure that the device is placed stably and ready for subsequent work. The material to be filled into the blasting hole is poured into the housing 1 through the feed hopper 4. At the same time as the material is poured in, the four first servo motors 501 are started to drive the four crushing rods 502 to rotate. After the material enters the housing 1, the high-speed rotation of the crushing rods 502 can effectively crush the falling large pieces of material, reducing their particle size to meet the processing requirements of subsequent processes. This can prevent large pieces of material from clogging the internal channels of the device or affecting the normal operation of subsequent screening and anti-clogging structures.

[0033] The crushed material falls downwards, supported by two sliding frames 601. The filter screen 603 inside the sliding box 602 filters the material; finer particles that meet the size requirements can pass through the filter screen 603 and continue falling, while larger particles remain inside the sliding box 602. By sliding the sliding box 602 inside the sliding frame 601, it is easy for workers to remove the sliding box 602 to clean the filter screen 603. This also facilitates the removal of larger or clump-like particles remaining on the filter screen 603. The material, after being screened, continues to fall to the bottom. Three second servo motors 701 drive the anti-blocking stirring rods 702 to rotate. The rotating anti-blocking stirring rods 702 can continuously stir the material passing through this point, preventing the material from accumulating and clumping in the lower part of the box 1 and at the inlet of the filling pipe 8, thus preventing blockage. This ensures the smooth passage of the material and provides a guarantee for subsequent output through the filling pipe 8. The material is finally transported from the box 1 to the mine blasting hole through the filling pipe 8, thereby completing the filling work of the blasting hole and achieving the purpose of sealing the blasting hole.

[0034] Throughout the operation, the operator can observe the status of the materials inside the device at any time through the observation window 2, including the falling of materials and whether there is any abnormal accumulation, so as to promptly identify any potential problems and take corresponding measures. At the same time, the operator can control various functional components through the control panel 3, such as controlling the start or stop of the first servo motor 501 and the second servo motor 701, and making appropriate adjustments to the device's operating parameters according to the actual operation conditions, so as to ensure that the device can adapt to different operation requirements and operate smoothly and efficiently.

[0035] In addition, the housing 1 is made of aluminum alloy, which is lightweight and has high strength. This facilitates the movement and transportation of the device and ensures the stability of the device structure to withstand various stresses and impacts generated during operation, providing basic structural support for the effective cooperation of various functional components and the normal operation of the whole device.

[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
