Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of perfusion devices, in particular to a perfusion device for static blasting breaking agent. BACKGROUND

[0002] The underground pipe gallery is a public tunnel space built in the city underground, which can centrally accommodate municipal pipelines such as power, communication, water supply and drainage and their auxiliary facilities for management and maintenance.

[0003] In the process of building the underground pipe gallery, if the underground rock is blocked, static breaking agent will be used for static blasting of the rock. The static breaking agent is generally a powdery material with calcium oxide as the main component. When used, a hole is opened on the rock, which is called a blast hole. Then the static breaking agent is mixed with water to form a slurry, which is then poured into the hole. After the slurry expands, it can support and break the large rock from the inside to the outside, achieving the breaking of the large rock.

[0004] In the prior art, the diameter of the blast hole is generally 3-5 cm. Due to the small cross section of the blast hole, the speed of the static breaking agent rising inside the blast hole is relatively fast during the perfusion process. If not properly controlled, when the static breaking agent rises to the top opening of the blast hole, it will overflow if the reaction is not fast enough. The overflow of the static breaking agent not only causes material waste, but also adheres to the surface of the rock around the blast hole or the construction equipment, increasing the cleaning workload. If the perfusion speed is slowed down to avoid the overflow of the static breaking agent, the perfusion efficiency will be reduced. If the perfusion speed is too slow, the slurry poured first may begin to set before the subsequent blast hole is completed, resulting in uneven transmission of the expansion pressure and ultimately affecting the breaking effect. SUMMARY

[0019] First, the fixing ring 5 is sleeved on the outer end of the bucket 4 and fixed, the bottom end of the stirring shaft 602 and the stirring blades 603 are inserted into the inside of the bucket 4, then the powder-like static breaking agent and water are poured into the bucket 4 according to the existing technology of mixing static breaking agent in proportion, the driving motor 601 is started, the stirring shaft 602 and the stirring blades 603 are driven to rotate by the driving motor 601, the rotation of the stirring blades 603 is utilized to uniformly mix the powder and water, and finally the static breaking agent slurry is formed, the slurry in the inside of the bucket 4 cannot be too full, and it is more convenient to control the slurry to pour out during filling, and the slurry in the inside of the bucket 4 is at most not more than two-thirds of the volume of the bucket 4.

[0020] Embodiment 2 of the present application: as shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the bottom end of the filling bucket 1 is fixedly provided with a filling nozzle 101 inserted into the inside of the blast hole 3, the filling nozzle 101 is located at the central position in the inside of the blast hole 3, and a gap is left between the outer side of the filling nozzle 101 and the inner wall of the blast hole 3; Both sides of the pouring hopper 1 are fixedly provided with side plates 102, the bottom end of the side plate 102 is provided with two tension components 8, the tension component 8 comprises an outer tube 801 fixedly provided at the bottom end of the side plate 102, a spring 802 is fixedly provided on the inner wall of the outer tube 801, an inner rod 803 is fixedly provided at the bottom end of the spring 802, the top end of the inner rod 803 is located in the outer tube 801, and the bottom end of the inner rod 803 extends to the bottom of the outer tube 801 and is fixedly provided with a pressing plate 804.

[0021] The pouring hopper 1 is placed at the opening of the top end of the blast hole 3, the sharp end at the bottom of the pouring hopper 1 is inserted into the blast hole 3 together with the pouring nozzle 101, then the pressing plate 804 is pushed by external force, so that the pressing plate 804 which is not in contact with the rock is pressed on the surface of the rock, in the process, the pressing plate 804 drives the inner rod 803 to move and lengthen the spring 802, the outer tube 801 is pulled by the elastic force of the spring 802, and then the pouring hopper 1 is pulled by the outer tube 801 and the side plate 102, so that the pouring hopper 1 is tightly attached to the opening of the blast hole 3.

[0022] Embodiment 3 of the present application: as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 7 The pouring hopper 1 and the barrel 4 are provided with a material guiding component 2, the material guiding component 2 comprises a material guiding belt 201, the bottom of the front end of the material guiding belt 201 is fixedly provided with a connecting piece 202, the pouring hopper 1 is fixedly provided with two inserting rods 104 for mounting the connecting piece 202, the top end of the inserting rod 104 penetrates through the connecting piece 202, and a nut is threadedly connected to the outer end of the inserting rod 104, so that the connecting piece 202 is fixed on the inserting rod 104, the connecting piece 202 is transversely arranged on the top end of the pouring hopper 1 and the front end of the material guiding belt 201 is fixed to the top end of the pouring hopper 1.

[0023] The material guiding component 2 further comprises a center winding shaft 203, the rear end of the material guiding belt 201 is fixedly connected to the outer end of the center winding shaft 203 and wound around the outer end of the center winding shaft 203, two limiting stop plates 206 are fixedly provided at the outer end of the center winding shaft 203, and the material guiding belt 201 is wound around the position between the two stop plates 206.

[0024] The end plates 204 are rotatably connected to both ends of the center winding shaft 203, the rear end of the end plate 204 is connected to the front side of the fixed ring 5, the stop plate 206 is provided with a torsional spring 205 away from the material guiding belt 201, one end of the torsional spring 205 is connected to the corresponding end plate 204, the torsional spring 205 is sleeved on the outer end of the center winding shaft 203, and the torsional spring 205 does not need too large elastic force, and can make the material guiding belt 201 which is pulled out and unfolded slightly tense.

[0025] Pull the guide belt 201 and the connecting piece 202, as the wound guide belt 201 is pulled out, the center reel 203 rotates accordingly, the torsional spring 205 is thus tightened and generates elastic force, the elastic force of the torsional spring 205 drives the center reel 203, tightens the guide belt 201, and then fixes the connecting piece 202 at the top end of the pouring hopper 1 through the insertion rod 104, so that the front end of the guide belt 201 is connected to the top end of the pouring hopper 1, and the guide belt 201 between the bucket 4 and the pouring hopper 1 is thus kept in an unfolded and straightened state; Then lift the bucket 4, and as much as possible, make the bucket 4 close to the top end of the pouring hopper 1 from back to front, and gradually tilt it. According to the operation experience, judge the possible falling point of the slurry when pouring, and constantly adjust the position of the bucket 4 during the tilting process, and then adjust the falling point of the slurry. Because of the existence of the guide belt 201, when adjusting the falling point, the falling point is allowed to be at the top end of the unfolded guide belt 201, so if the falling point cannot be accurately grasped, the falling point is adjusted to the top end of the obviously rear guide belt 201. When the inclination angle of the bucket 4 is greater than a certain degree, the slurry in the bucket 4 will be poured out. If the falling point is accurately judged, the poured slurry will form a liquid column and directly fall into the pouring hopper 1. Even if it is not accurate, the falling point falls on the top end of the guide belt 201, and the slurry will finally flow into the pouring hopper 1 along the inclined guide belt 201. This way makes the slurry not fall on other positions outside the pouring hopper 1, reducing the waste of slurry. Then adjust the falling point position under the condition that the falling point has been formed, and move the falling point from the top end of the guide belt 201 to the pouring hopper 1, so that the slurry accurately falls into the pouring hopper 1. This way has higher fault tolerance, even if the falling point of the slurry is not accurately judged, it will not cause waste of slurry, and the falling point can be further adjusted to the accurate position to avoid waste of slurry caused by inaccurate falling point when pouring slurry; In addition, the falling point can also not be adjusted, and the slurry can be directly poured on the top end of the guide belt 201, so that the slurry flows into the pouring hopper 1 along the guide belt 201. The advantage of this operation is that the bucket 4 does not need to be too close to the pouring hopper 1, and the pouring hopper 1 is relatively low, so the bucket 4 is appropriately away from the pouring hopper 1, which can make the operator not too bent over, and the operation is more convenient. The operator can choose the pouring method flexibly according to the actual situation. In reality, the bucket 4 can also be directly poured against the top end of the pouring hopper 1, but this requires the operator to bend over or even squat, which is very inconvenient, so this way is generally not used.

[0026] Since the guide belt 201 is located on the front of the material bucket 4, the slurry falls at the center of the guide belt 201. After the slurry falls to the top of the guide belt 201, the middle part of the guide belt 201 will be concave due to the weight of the slurry, thus preventing the slurry from flowing to the side of the guide belt 201. In addition, although there are existing grouting devices that transport slurry through pipelines, the devices themselves are large and inconvenient to handle and carry during construction. Furthermore, such grouting devices have dedicated, relatively closed slurry containers and long, narrow pipes, making cleaning and maintenance after use inconvenient. Therefore, in actual construction, the method of mixing the slurry in a bucket and pouring it into the blast hole 3 using a funnel is more commonly used. In this invention, the material bucket 4 can be selected from various types of buckets, and the materials are readily available. The fixing ring 5 and the mounting bracket 6 can be disassembled and sorted from the material bucket 4. Furthermore, the material bucket 4 is not enclosed and does not have too many long and narrow enclosed pipes, making it more convenient to carry, clean, and maintain. On this basis, the problem of inaccurate pouring and pouring points is also solved.

[0027] Embodiment 4 of the present invention: Figures 2-4 As shown, two exhaust channels 9 are fixedly provided on the inner wall of the injection hopper 1 for discharging air from the inside of the borehole 3. The top of the exhaust channel 9 can be connected to an extended hose, and the hose extends to the outside of the injection hopper 1 to prevent the slurry poured out of the material bucket 4 from entering the exhaust channel 9. The bottom of the exhaust channel 9 is connected to the borehole 3. A hollow scale rod 7 is provided at the center of the inside of the injection hopper 1. The bottom of the hollow scale rod 7 extends into the inside of the borehole 3 through the injection nozzle 101. Because the hollow scale rod 7 is hollow, the overall density of the hollow scale rod 7 is less than the density of the static crushing agent. The hollow scale rod 7 is fitted with a collar 701 at its outer end. Two connecting arms 702 connected to the inner wall of the filling hopper 1 are fixedly provided at the outer end of the collar 701. A sponge ring is fitted at the bottom end of the collar 701 and fitted at the outer end of the hollow scale rod 7. A top plate is fixedly provided at the top end of the hollow scale rod 7. An arc-shaped surrounding plate 103 is fixedly provided at the rear side of the top end of the filling hopper 1. The surrounding plate 103 can block the slurry poured out of the material bucket 4 and prevent the slurry from falling too far forward when it is poured out and landing in front of the filling hopper 1.

[0028] The slurry falling into the pouring bucket 1 falls along the inner wall of the pouring bucket 1 and finally flows into the blast hole 3 through the pouring nozzle 101, and the diameter of the pouring nozzle 101 is smaller than the inner diameter of the blast hole 3, so that the diameter of the liquid column formed when the slurry flows out of the bottom end of the pouring nozzle 101 is also smaller than the inner diameter of the blast hole 3, so that when the slurry fills the space inside the blast hole 3 from bottom to top, the air inside the blast hole 3 squeezed by the slurry will flow upward through the gap between the outside of the liquid column and the inner wall of the blast hole 3 and finally be discharged through the exhaust passage 9, thereby avoiding the pouring bucket 1 blocking the top end of the blast hole 3 and causing poor air exhaust, and also avoiding the liquid column entering the blast hole 3 being too thick to block the passage of gas flowing in the blast hole 3, thereby causing poor pouring; Under normal circumstances, the hollow scale rod 7 is naturally inserted into the blast hole 3 under the action of gravity, and the top plate is blocked at the top end of the collar 701, blocking the further downward movement of the hollow scale rod 7. As the slurry is poured, the blast hole 3 is gradually filled, and when the slurry poured in the blast hole 3 moves to the bottom end of the hollow scale rod 7 near the opening of the blast hole 3, because the overall density of the hollow scale rod 7 is smaller than the density of the slurry, the slurry that continues to move upward will make the hollow scale rod 7 float and move upward with the slurry. When the operator observes that the hollow scale rod 7 has moved significantly upward, it indicates that the height of the slurry has approached the opening at the top end of the blast hole 3, and the blast hole 3 is about to be filled. At this time, the pouring speed should be slowed down, and the change in the slurry inside the blast hole 3 should be observed through the scale change of the hollow scale rod 7 at the collar 701 until the blast hole 3 is filled; When the slurry stops moving downward inside the pouring nozzle 101, it indicates that the blast hole 3 has been filled. At this time, if the operator does not react in time and overfills, causing a small amount of slurry to remain inside the pouring bucket 1, the hollow scale rod 7 can be pulled upward and extracted from the collar 701. The slurry on the surface of the hollow scale rod 7 will be wiped clean by the sponge ring, and although the density of the hollow scale rod 7 is smaller than that of the slurry, a part of the bottom end of the hollow scale rod 7 will still be immersed in the slurry. As the hollow scale rod 7 is extracted, the liquid surface of the slurry will drop, thereby causing the liquid surface that has overflowed into the pouring bucket 1 to fall back down, thereby greatly reducing the residual slurry; Therefore, by setting the overall density of the hollow scale rod 7 to be smaller than that of the slurry, the rise and fall of the hollow scale rod 7 can provide an early warning when the slurry is about to be filled, so as to slow down the pouring speed in time and avoid the slurry overflowing due to a delayed reaction. In addition, a part of the bottom end of the hollow scale rod 7 is immersed in the slurry, so that even if a small amount of slurry overflows, the slurry will fall back after the hollow scale rod 7 is extracted. The presence of the hollow scale rod 7 leaves a certain amount of space for the overflowing slurry to fall back, reducing the residual slurry overflow and waste, and ensuring the efficiency of the pouring process. The slurry can also be uniformly solidified, ensuring uniform transmission of expansion pressure and ensuring the effectiveness of rock breaking.
