Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mining blasting technology, specifically a mining blasting hole filling machine. Background Technology
[0002] Mining blasting is a crucial step in mining operations. It utilizes the enormous energy generated by explosive explosions to break and separate ore from the rock mass in order to obtain the desired mineral resources. The filling of blast holes is of paramount importance. The filling operation is carried out after the explosives are placed. It prevents the explosive gases from escaping prematurely and allows the explosive energy to fully act on the ore for crushing.
[0003] The existing mine blasting hole packing machine still has the following shortcomings: The existing mine blasting hole packing machine has low screening and filtration efficiency for sand and gravel. The existing mine blasting hole packing machine uses a spherical protrusion filter screen fixed on the top of the device to screen and filter large pieces of sand and gravel. The screening and filtration efficiency is low. When a large amount of sand and gravel rushes in in a short period of time, the filter screen cannot screen and filter in time, which can easily cause sand and gravel to accumulate and block the blockage. It requires the staff to clean it, which is relatively troublesome to use. Utility Model Content

The guide component transports the qualified sand and gravel along the guide pipe 4 to the vertical pipe 5. The vertical pipe 5 is set above the blast hole for convenient and accurate feeding. The qualified sand and gravel fall directly into the blast hole. After the filling is completed, the electric telescopic rod 6 is activated. The output end of the electric telescopic rod 6 can drive the pressing disc 7 to press down, which efficiently compacts the sand and gravel in the blast hole. Compared with the traditional manual compaction, its compaction effect is more uniform and stable, greatly enhancing the tightness of the filling and improving the blasting effect.
[0024] The screening assembly includes a pair of guide rods 8, both of which are fixedly connected to the inner wall of the hopper 1. Each guide rod 8 is slidably connected to a sliding block 9.

A discharge plate 11 is fixedly connected to one side of the screening frame 10. A discharge port is opened on one side of the hopper 1. The transmission assembly drives the screening frame 10 to move. The screening frame 10 slides back and forth between the pair of guide rods 8 through the sliding blocks 9 on both sides. Sand and gravel fall onto the screening frame 10. The screening frame 10 can vibrate and screen the sand and gravel. The sand and gravel can fully contact the screen on the screening frame 10, which greatly improves the screening efficiency of the sand and gravel. The screening frame 10 is slightly tilted. Large pieces of sand and gravel roll down through the screening frame 10 onto the discharge plate 11 and then are discharged onto the ground through the discharge plate 11.
[0025] The transmission assembly includes a servo motor 12, which is fixedly connected to the bottom of the mounting base 2. The output end of the servo motor 12 is coaxially fixedly connected to a transmission shaft. A pulley 13 is coaxially fixedly connected to the transmission shaft.

A connecting cylinder is fixedly connected to one side of the rotating disk 14 away from the axis. A connecting rod 15 is rotatably connected to one end of the connecting cylinder. A connecting block 16 is rotatably connected to one end of the connecting rod 15. One side of the connecting block 16 is fixedly connected to the screening frame 10. When the servo motor 12 is started, the output end of the servo motor 12 drives the transmission shaft to rotate. The pulley 13 and the rotating disk 14 both rotate together with the transmission shaft. The rotating disk 14 drives the connecting block 16 to reciprocate through the connecting cylinder and the connecting rod 15. The connecting block 16 drives the screening frame 10 to move together.
[0026] The material guiding assembly includes a rotating shaft, which is rotatably connected to the material guiding pipe 4. A spiral blade 17 is coaxially fixedly connected to the rotating shaft.

The rotating disk 14 drives the connecting block 16 to reciprocate through the connecting cylinder and the connecting rod 15. The connecting block 16 drives the screening frame 10 to move together. The screening frame 10 slides back and forth between a pair of guide rods 8 through the sliding blocks 9 on both sides. At the same time, the pulley 13 drives the pulley 18 to rotate through the belt. The pulley 18 drives the spiral blade 17 to rotate through the rotating shaft.
[0032] Workers use shovels to shovel sand and gravel from the ground into the feed inlet 19. The sand and gravel fall through the feed inlet 19 onto the screening frame 10 inside the hopper 1. The screening frame 10 can vibrate and screen the sand and gravel, allowing them to fully contact the screen on the screening frame 10, which greatly improves the screening efficiency. The screening frame 10 is slightly tilted, and large pieces of sand and gravel roll through the screening frame 10 onto the discharge plate 11, and then are discharged onto the ground through the discharge plate 11. The qualified sand and gravel fall through the discharge port 3 at the bottom of the hopper 1 into the gap of the spiral blades 17 in the guide pipe 4. The spiral blades 17 push the qualified sand and gravel along the guide pipe 4 to be transported into the vertical pipe 5. The vertical pipe 5 is set above the blast hole for convenient and accurate feeding. The qualified sand and gravel fall directly into the blast hole.
[0033] After the filling is completed, the electric telescopic rod 6 is activated.
