Description

Technical Field

[0001] This utility model relates to the field of rock blasting technology, specifically to an auxiliary charging device for breaking rock strata. Background Technology

[0002] Blasting is a technique that utilizes the compression, loosening, destruction, throwing, and killing effects produced by the explosion of explosives in air, water, soil, rock, or objects to achieve a desired purpose. When explosive charges or charges explode in soil, rock, or structures, they cause compression, deformation, destruction, loosening, and throwing of the soil, rock, or structures. Blasting is widely used in tunnel construction and mining.

[0003] In existing technologies, rock breaking typically involves operators using a pre-fixed funnel to precisely pour explosives into the charging hole. However, the discharge port at the bottom of the funnel is small, which can easily cause blockage of the explosives and affect the charging efficiency. Therefore, a rock breaking auxiliary charging device is needed. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary charging device for breaking rock strata, which solves the problems mentioned in the background art.

[0005] This application provides an auxiliary charging device for breaking rock strata, including a base. A fixed plate and a vertical plate are sequentially arranged from left to right at the top of the base. A through-hole is formed at the top of the base, located between the fixed plate and the vertical plate. A bidirectional motor is installed on the side of the fixed plate away from the vertical plate. The output shaft of the bidirectional motor passes through the fixed plate and is fixedly connected to a funnel, which is located above the slot. A rotating rod is rotatably connected to the outer wall of the vertical plate facing the funnel. The end of the rotating rod away from the vertical plate is fixedly connected to the funnel. Two limiting blocks are fixedly connected to the outer wall of the vertical plate on the side of the rotating rod, respectively located on both sides of the rotating rod. A fixed sleeve is fixedly fitted onto the rotating rod, and a connecting block is fixedly connected to the bottom end of the fixed sleeve.

[0006] In use, explosives can be poured into the funnel and then fed into the orifice through the tube. The bidirectional motor can rotate the funnel left and right, shaking it to prevent the explosives from clogging. The rotating rod and vertical plate support one side of the funnel, reducing the load on the output shaft of the dual motor without affecting the rotation of the funnel. At the same time, the limiting block, fixing sleeve and connecting block can limit the rotation angle of the funnel, preventing the explosives from not accurately entering the orifice due to a large rotation angle. It is convenient and practical, and improves the efficiency of loading explosives.

[0007] Optionally, a tube is fixedly connected to the bottom end of the funnel.

[0008] By adopting the above technical solution, the explosive can be more accurately delivered into the blast hole through the tube.

[0009] Optionally, rubber blocks are attached and fixed to the inner walls on both sides of the groove.

[0010] By adopting the above technical solution, it is possible to avoid damage and deformation of the pipe body caused by collision with the base when the funnel drives the pipe body to shake.

[0011] Optionally, universal self-locking wheels are installed at the four corners of the bottom of the base.

[0012] By adopting the above technical solution, the base can be moved flexibly.

[0013] Optionally, a handle is fixedly connected to one side of the outer wall of the base.

[0014] By adopting the above technical solution, operators can more flexibly move the base.

[0015] Optionally, a dust-proof plate is fixedly connected to the outer wall of the fixed plate facing the vertical plate, and the dust-proof plate is located above the funnel.

[0016] By adopting the above technical solution, the dust-blocking effect of the funnel can be improved by using the dust-blocking plate.

[0017] Optionally, the diameter of the tube body is smaller than the diameter of the medicine hole.

[0018] By adopting the above technical solution, the leakage of explosives can be avoided.

[0019] Optionally, the fixing sleeve and the connecting block are an integral structure.

[0020] By adopting the above technical solution, the firmness of the fixing sleeve and connecting block can be improved, and breakage can be avoided.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] The technical solution of this application uses a bidirectional motor to drive the funnel to rotate left and right, shaking the funnel to prevent the explosive inside the funnel from clogging. The rotating rod and vertical plate support one side of the funnel, which reduces the load on the output shaft of the bidirectional motor and does not affect the rotation of the funnel. At the same time, under the action of the limiting block, the fixing sleeve and the connecting block, the rotation angle of the funnel can be limited, preventing the explosive from not being able to accurately enter the explosive hole when the rotation angle is too large. It is convenient and practical and improves the efficiency of loading explosives. Attached Figure Description

[0032] In the technical solution of this utility model, such as Figure 3As shown, universal self-locking wheels 5 are installed at the four corners of the bottom of the base 10, which facilitates the flexible movement of the base 10.

[0033] In the technical solution of this utility model, such as Figure 1 As shown, a handle 4 is fixedly connected to one outer wall of the base 10, which makes it easier for the operator to push the base 10 more flexibly.

[0035] In the technical solution of this utility model (not shown), the diameter of the tube body 8 is smaller than the diameter of the explosive hole; this can prevent the explosive from spilling.

[0036] In the technical solution of this utility model, such as Figure 4 As shown, the fixing sleeve 13 and the connecting block 14 are an integral structure; this helps to improve the firmness of the fixing sleeve 13 and the connecting block 14 and avoid breakage.
