Description
Technical Field
[0001] The utility model relates to the technical field of blasthole cleaning, in particular to a blasthole cleaning device. Background Art
[0002] During mine blasting, blastholes need to be opened first. During the blasthole opening process, gravel will fall to the bottom of the hole. At the same time, some gravel from the mountain will also fall to the bottom of the hole. These gravel will block the blasthole and affect the normal filling of the explosives. In order to ensure that the explosives can be installed normally, the gravel needs to be manually removed.
[0003] For example, Chinese patent application number CN201810990536.0 discloses a negative pressure blasthole slag cleaning device for tunnel surrounding rock blasting, the specific content of which is: by setting a driving mechanism, an exhaust mechanism, a ventilation pipe and a first through hole, the ventilation pipe is inserted into the blasthole, the driving mechanism is turned on, and the second fan blade is driven to rotate through the first and third rotating shafts to generate negative pressure in the second shell, and the air in the blasthole is sucked into the interior of the second shell through the first and fifth through holes in turn. The dust in the blasthole follows the airflow into the interior of the second shell, and the dust in the air is blocked by the filter plate, so that the dust accumulates in the second shell, and the dust in the blasthole is cleaned. However, the following technical problems exist:
[0004] In the prior art, only dust in the blasthole can be removed by negative pressure adsorption of the blasthole. It is difficult to clean gravel that is heavier than dust, and the gravel can easily clog the dust conveying pipe. Therefore, it is difficult to clean the gravel in the blasthole. Utility Model Content
[0005] In order to solve the problem of difficulty in cleaning gravel in blastholes raised in the above background technology, the present invention provides the following technical solutions:
[0006] A blasthole cleaning device comprises a barrel extending into the blasthole, a top of the barrel being provided with a push rod, and a bottom of the barrel being provided with a support block;
[0007] Electromagnets are fixedly installed around the support block, and support rods are installed on the edge of the support block. The support rods are fixedly connected to the inner wall of the cylinder, and there are four groups of support rods in total;
[0008] An inner rod is fixedly mounted on the side of the support block close to the electromagnet, and the outer end of the inner rod is fixedly connected to the inner wall of the cylinder. An iron cylinder is sleeved on the outer side of the inner rod, and a tension spring a is sleeved on the side of the inner rod close to the iron cylinder, and one end of the tension spring a is fixedly connected to the iron cylinder, and the other end of the tension spring a is fixedly connected to the inner wall of the cylinder;
[0009] A fan-shaped plate is fixedly installed at the bottom of the iron cylinder, and the fan-shaped plate is located at the bottom of the cylinder. A blocking cloth for limiting the gravel is installed between the two fan-shaped plates;
[0010] A switch button is fixedly installed on one side of the top of the push rod, and the signal output end of the switch button is connected to the signal input end of the electromagnet, which can be used in conjunction with components such as the fan-shaped plate, the tension spring b and the electromagnet. During the use of the blasthole cleaning device, the cylinder is located at the bottom of the blasthole, and then the electromagnet is closed. The force of the tension spring causes the iron cylinder to move along the inner rod, and the iron cylinder simultaneously drives the fan-shaped plate to move outward, and the cylinder is moved up and down by manpower at the same time. The four groups of fan-shaped plates extend to the outside of the cylinder and are located under the gravel. Then the extraction device is pulled out to separate it from the blasthole, and the gravel brought out is cleaned. This structure effectively improves the cleaning efficiency and is highly practical.
[0011] Furthermore, a hinge is installed on one side of the junction of the push rod and the cylinder, and a protrusion is fixedly installed on the side of the push rod and the cylinder facing away from the hinge. A T-bar passes through the middle of the protrusion, and the upper end of the T-bar is sleeved with a tension spring b. The top end of the T-bar is connected to the protrusion through the tension spring b, and can be used in conjunction with components such as the hinge and the T-bar. After a single blast hole is cleaned, the T-bar can be moved outward by applying force during the carrying process of the device, so that the position of the protrusion is no longer restricted, and the push rod is rotated synchronously to fold the push rod to one side of the cylinder, which can reduce the length of the device and facilitate manual carrying. At the same time, the T-bar limiting method is easy to disassemble and adjust, and the use effect is more ideal.
[0012] Furthermore, a battery is fixedly installed on the top of the top rod, and the battery is electrically connected to the electromagnet through a wire. The battery can provide power to avoid pulling too long wires, which meets the use requirements of the mobile device.
[0013] Furthermore, grips are fixedly installed on both sides of the top of the top rod, and anti-slip sleeves are fixedly installed on the grips. The top rod can be gripped by the grips to facilitate the carrying and lifting of the device. At the same time, the anti-slip sleeves can increase the grip friction to prevent slipping.
[0014] Furthermore, an indicator sticker is glued to one side of the push rod close to the grip rod, and guiding text is printed on the indicator sticker. The operator can be informed of the corresponding process through the indicator sticker and the guiding text, which is convenient for different personnel to operate and use.
[0015] Compared with the prior art, the beneficial effects of the present invention are:

The four groups of fan-shaped plates extend to the outside of the cylinder and are located under the gravel. Then the extraction device is pulled out to separate it from the blasthole, and the gravel brought out is cleaned. This structure effectively improves the cleaning efficiency and is highly practical.
[0017] 2. The utility model is provided with a hinge and a T-bar. After a single blasthole is cleaned, the T-bar can be moved outward by applying force during the transportation of the device, so that the position of the protrusion is no longer restricted. The top rod is rotated synchronously to fold the top rod to one side of the barrel, which can reduce the length of the device and facilitate manual transportation. At the same time, the T-bar limiting method is easy to disassemble and adjust, and the use effect is more ideal. BRIEF DESCRIPTION OF THE DRAWINGS
