[0030] Aiming at the problem that the traditional pumping device in the prior art has a low recovery rate of returned powder and residual explosives, resulting in serious waste of explosives, the utility model proposes a powder residual collection device to improve workers' work efficiency and reduce safety hazards.

[0031] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] This embodiment discloses a device for collecting powdery residual medicine. Figure 1 The entire three-dimensional structure of the powdery residual medicine collecting device is shown. Figure 2 The three-dimensional structure of the catheter involved in the powdery residual medicine collection device is shown.

[0033] Please refer to Figure 1 and Figure 2The powdery residual drug collection device of the present invention comprises: a conduit 1, an opening 11 provided on the conduit 1, a charging tube 3 inserted into the opening 11, and a collection assembly provided at the lower end of the conduit 1. The conduit 1 is hollow, with one end of the conduit 1 disposed at the end of the charging hole 2 and the other end disposed within the collection assembly. The conduit 1 not only ensures the smooth installation of the explosives but also avoids the generation of excessive powdery residual drug during the installation process. One end of the charging tube 3 extends into the opening 11 and is inserted into the conduit 1. The charging tube 3 is used to install the explosive into the charging hole 2. The conduit 1 allows construction workers to accurately insert the charging tube 3 into the charging hole 2, ensuring accurate installation of the explosives. The collection assembly is used to collect the returned powdery residual drug, which can be put into the next wave of use, saving costs.

[0034] The conduit 1 is a plastic round tube. Plastic not only has good corrosion resistance and can maintain stable performance, but also is anti-static and flame-retardant, ensuring a long service life of the conduit 1. It is also lightweight, making installation and transportation more convenient and easy to install and operate, thereby improving the work efficiency of construction workers.

[0035] In this embodiment, the conduit 1 is a plastic round tube. In a specific embodiment, a suitable material can be selected for production according to actual conditions. The material is not limited to the materials described above. It only needs to be light and able to effectively prevent the generation of static electricity.

[0036] The length of the conduit 1 is greater than the depth of the charge hole 2. A sufficiently long conduit 1 ensures that the conduit 1 can be fully inserted into the charge hole 2 to achieve the best collection effect.

[0037] The opening 11 is elliptical, with the minor axis of the opening 11 being equal to the diameter of the conduit 1. This elliptical shape not only facilitates the insertion of the charge tube 3 but also facilitates its vertical rotation. When explosives are installed in the charge tube 3, the charge tube 3 can fit snugly against the opening 11. The equalization of the minor axis of the opening 11 and the diameter of the conduit 1 also allows the charge tube 3 to fit snugly against the conduit 1 during insertion, minimizing the gap between the opening 11 and the charge tube 3 and reducing explosive dropout. This ensures that the explosives can fall along the conduit 1 into the collection assembly, avoiding leakage due to size mismatch. Furthermore, this design makes the charge tube 3 more flexible when bending, further improving the reliability of the entire system.

[0038] The outer diameter of the charge tube 3 is smaller than the inner diameter of the guide tube 1. In order to ensure accurate installation of the explosives, the outer diameter of the charge tube 3 needs to be small, which facilitates the flexible movement of the charge tube 3 in the guide tube 1 and ensures smooth operation of the explosives installation.

[0039] The collection assembly includes a collection bag 4 and a collection basket 5. The collection bag 4 has a first opening at its upper end and a second opening at its lower end. The first opening is sleeved onto the lower end of the conduit 1, and the collection basket 5 is positioned below the second opening. The collection basket 5 is used to collect returned powder residues. Once the explosives are installed, the powder residues will fall down the conduit 1 and first enter the collection bag 4. The collection bag 4 has a second opening at its lower end, which is connected to the collection basket 5. The main function of the collection basket 5 is to collect the powder residues that fall from the collection bag 4. Collecting the powder residues together facilitates subsequent processing and reuse.

[0040] The first opening is a retractable opening. When installing the collection assembly, after the catheter 1 is fixed, the collection bag 4 is placed on the lower end of the catheter 1 and the first opening is retracted to better fix the collection bag 4 on the catheter 1 to prevent it from falling. By tightening the first opening, both hands can be freed and manpower can be reduced.

[0041] The diameter of the second opening is smaller than the diameter of the collecting basket 5. The smaller diameter of the second opening facilitates the collection of the fallen powdered drug residues to be better collected by the collecting basket 5. Improving the collection basket 5 not only greatly reduces the scattering and waste of powdered drug residues, but also facilitates subsequent processing and reuse. In other embodiments, the second opening can be closed to allow the powdered drug residues to fall directly into the collection bag 4. There is no need to place the collecting basket 5 at the lower end of the collection bag 4. In this case, the construction personnel need to fix the collection bag 4 to prevent the powdered drug residues from being too heavy, causing the collection bag 4 to fall from the catheter 1, affecting the construction efficiency.

[0042] The collection bag 4 is an anti-static cloth bag, and the collection basket 5 is an anti-static basket. Such materials can effectively prevent the generation and accumulation of static electricity, avoid explosions of explosives caused by static electricity, lead to fires and other safety accidents, and ensure the safety of construction workers.

[0043] In another embodiment, a plastic film can be passed through the charge tube 3, the plastic film fits tightly to the charge tube 3, and the plastic film can cover the opening 11, which can effectively prevent the explosives from falling from the opening 3. In addition, the plastic film is elastic and will not be easily damaged, and will not affect the up and down movement of the charge tube 3.

[0044] To sum up, when it is necessary to blast a mine, first extend one end of the catheter 1 into the set charging hole 2 until the top of the catheter 1 reaches the deepest part of the charging hole 2. After fixing the catheter 1, extend the charging tube 3 into the catheter 1 through the opening 11 and reach the charging hole 2 to install the explosives. The powdery residue dropped during charging falls along the catheter 1, passes through the collection bag 4, and falls into the collection basket 5, which is convenient for next use.

[0045] In short, the utility model eliminates the phenomenon of powdered residual explosives returning during medium-deep hole blasting and charging operations, improves the safety factor, standardizes the blasting and charging operations to a certain extent, and ensures the safety of construction workers. By re-using the powdered residual explosives, costs are saved to a certain extent.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
