Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to a continuous pushing charging machine for deep-hole blasting in coal mines. Background Technology

[0002] Deep-hole blasting technology plays an important role in solving problems such as coal and gas outbursts and loosening of the upper coal seam in top coal caving mining. In deep-hole blasting, loading explosives into blast holes tens of meters deep and ensuring reliable detonation of the explosives are the key to the implementation of deep-hole blasting. Therefore, it is necessary to study the loading method.

[0003] When loading explosives, the coal dust or rock dust in the blast hole must first be removed with a scoop or compressed air. Then, the explosive cartridge is gently pushed in with a wooden or bamboo tug, without bumping or tamping. The explosive cartridges in the blast hole must be in close contact with each other. Traditionally, explosives are loaded manually, and before loading, a depth check, slope check, humidity check, and check for any remaining impurities in the blast hole are required. During loading, the blast hole must be cleaned first, and then the explosive cartridge is pushed into the blast hole with a tug. The whole process takes a long time, and manual loading of explosives is still quite dangerous. The cleaning and various checks of the blast hole must be done manually, and during the process of pushing in the explosive cartridge, some impurities may be generated in the blast hole due to friction between the explosive cartridge, the tug, and the inner wall of the blast hole. These impurities are difficult to remove. If there are too many impurities or the blast hole collapses, which seriously damages the explosive loading, loading must be stopped for cleaning. Currently, it is also difficult to remove the explosive from the blast hole and reload it after loading. Summary of the Invention

[0004] This invention is based on the inventor's discovery and understanding of the following facts and problems: in related technologies, manual cleaning and inspection are required before loading explosives, which is time-consuming, and it is difficult to remove the explosive cartridge after the blast hole is damaged. This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, embodiments of this invention propose a continuous pushing charging machine for deep-hole blasting in coal mines, which has the advantages of convenient and efficient loading and unloading of explosives, and automatic cleaning and inspection without manual intervention.

[0005] According to an embodiment of the present invention, a continuous pushing charging machine for deep-hole blasting in coal mines includes a body, a charging mechanism, a cleaning mechanism, a clamping structure, a storage mechanism, and a material unloading mechanism. A lifting platform is mounted on the body and is movable vertically relative to the body. The charging mechanism includes a charging cylinder and a charging rod. The charging cylinder is pivotally connected to the lifting platform. The charging rod is located on the charging cylinder, and a humidity sensor is mounted on the first end of the charging rod to check the humidity inside the blast hole. The cleaning mechanism includes a blowing section and a scraping section. The blowing section is connected to the charging rod for blowing air, and the scraping section is connected to the first end of the charging rod for cleaning the blast hole. The clamping structure includes a push plate and a pressure sensor. The push plate is movably connected to the delivery cylinder.

At least a portion of the elastic rod is located inside the air bladder. Initially, the elastic rod is located inside the delivery rod. When air is supplied to the inside of the delivery rod to open the air bladder, the movable seat moves closer to the air bladder, and the elastic rod moves out of the inside of the delivery rod. Under the elastic action of the elastic rod, the elastic rod bends upward and opens, providing a certain degree of support for the air bladder.

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] According to embodiments of the present invention, a continuous pushing charging machine for deep-hole blasting in coal mines, such as... Figures 1 to 12As shown, the continuous push-loading charging machine for deep-hole blasting in coal mines includes a body 1, a charging mechanism, a cleaning mechanism, a clamping structure, a storage mechanism, and a discharge mechanism. A lifting platform 2 is mounted on the body 1 and can move up and down relative to the body 1. The charging mechanism includes a charging cylinder 101 and a charging rod 102. The charging cylinder 101 is pivotally connected to the lifting platform 2. The charging rod 102 is located on the charging cylinder 101. A humidity sensor 4 is installed at the first end of the charging rod 102 to check the humidity inside the blast hole. The cleaning mechanism includes a blowing section and a scraping section. The blowing section is connected to the charging rod 102 for blowing air, and the scraping section is connected to the first end of the charging rod 102 for cleaning the blast hole. The clamping structure includes a push plate 401 and a pressure sensor 402. 401 is movably connected to the delivery cylinder 101. The pressure sensor 402 is located on the side of the push plate 401 adjacent to the machine body 1. The storage mechanism includes a support frame 501, an explosive box 502, and a detonator box 503. The support frame 501 is connected to the lifting platform 2. A material discharge port is provided on the support frame 501. The explosive box 502 and the detonator box 503 are located on the support frame 501 and are symmetrically arranged about the material discharge port. Both the explosive box 502 and the detonator box 503 are provided with discharge ports. The material discharge structure includes a baffle block 602 and a sliding plate 601. The sliding plate 601 is located inside the explosive box 502 and the detonator box 503 to guide the material to slide down. The baffle block 602 is movably arranged in the explosive box 502 and the detonator box 503 to restrict the material from falling through the discharge port. The explosive box 502 and detonator box 503 of the storage mechanism move on the support frame 501 to feed the explosives and detonators. The feeding mechanism guides the explosives and detonators into the feeding mechanism. The pressing mechanism presses the explosives in the feeding mechanism. The cleaning mechanism cleans the inner wall of the blast hole to ensure cleanliness during the charging process. The feeding mechanism checks the humidity inside the blast hole through the humidity sensor 4. The delivery cylinder 101 is rotatably connected to the lifting platform 2 via a ball joint 103. The ball joint 103 allows the delivery cylinder 101 to rotate at multiple angles, adapting to the loading of explosives into boreholes at different angles. The delivery cylinder 101 is equipped with a screw feed mechanism 104, and the delivery rod 102 is mounted on the nut of the screw feed mechanism 104. The screw feed mechanism 104 drives the delivery rod 102 to move. Explosives are placed on the delivery rod 102. The delivery rod 102 moves into the borehole, allowing the explosives to enter the borehole. The delivery rod 102 enters along the borehole, and as it enters, its angle matches the borehole. The ball joint 103 causes the receiving cylinder 802 to rotate to an angle matching the borehole, facilitating subsequent explosive loading.

[0029] The continuous pushing charging machine for deep-hole blasting in coal mines according to embodiments of the present invention has the advantages of convenient charging and retrieval of explosives, high efficiency, and automatic cleaning and inspection without the need for manual intervention.

[0030] In some embodiments, the purging section includes an air inlet cylinder 301, a one-way valve 303, and a purging nozzle 302. The air inlet cylinder 301 is connected to the drug delivery rod 102, and an air inlet pipe is provided on the air inlet cylinder 301. The purging nozzle 302 is connected to the drug delivery rod 102 through an air outlet pipe. The one-way valve 303 is provided on the air outlet pipe. The scraping section includes an air bag 304, and the air bag 304 is connected to the air outlet pipe.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, the air inlet pipe is connected to an external air supply device, an external air extraction device, or an integrated suction device. The external air supply device supplies air into the air inlet cylinder 301 and the delivery rod 102. The delivery rod 102 has a hollow structure. Air is supplied to the airbag 304 through the delivery rod 102, which inflates the airbag 304. After the airbag 304 is inflated, it can block the explosive. At the same time, the airbag 304 enters the inside of the blast hole and contacts the inner wall of the blast hole. The airbag 304 moves inside the blast hole with the delivery rod 102, so that the airbag 304 can scrape the impurities on the inner wall of the blast hole. At the same time, the gas in the delivery rod 102 is blown out through the one-way valve 303 and the purging nozzle 302 to purge the inside of the blast hole, further reducing the impurities in the blast hole and facilitating the loading of explosives. There is a certain gap between the explosive and the blast hole. After the explosive is loaded, the external air extraction device extracts air from the air inlet cylinder 301, thereby extracting the gas from the air bag 304 and making the air bag 304 stick tightly to the surface of the delivery rod 102. This prevents the explosive from blocking the air bag 304 and allows the delivery rod 102 to be pulled out of the blast hole. Under the action of the one-way valve 303, the purge nozzle 302 is prevented from extracting air from the blast hole, thus preventing impurities from being sucked into the purge nozzle 302 and causing blockage.

[0032] In some embodiments, the deep-hole blasting continuous push-loading charging machine in coal mines further includes a support mechanism, which includes a movable seat 1001 and an elastic rod 1002. The movable seat 1001 is located inside the delivery rod 102 and can move along the delivery rod 102. One end of the elastic rod 1002 is connected to the movable seat 1001, and at least a portion of the elastic rod 1002 is located inside the airbag 304.

[0033] Specifically, such as Figure 5As shown, the push-pull rod 1004 and the delivery rod 102 correspond one-to-one. The push-pull rod 1004 extends into the delivery rod 102 and is connected to the moving seat 1001. The moving seat 1001 has a vent for gas to pass through the delivery rod 102. The elastic rod 1002 is mounted on the moving seat 1001 and is located inside the airbag 304. In its initial position, the elastic rod 1002 is located inside the delivery rod 102. When gas is supplied to the delivery rod 102 to open the airbag 304, the push-pull rod 1004 moves, causing the moving seat 1001 to move closer to the airbag 304. The elastic rod 1002 moves out of the delivery rod 102. Under the elastic action of the elastic rod 1002, the elastic rod 1002 bends upward and opens, opening the airbag 304. 4. Provide a certain degree of support to reduce the deformation of the airbag 304. At the same time, when it is necessary to remove the explosive or detonator from the borehole, the screw feed mechanism 104 drives the feed rod 102 to move outward, and the explosive comes into contact with the airbag 304. The explosive is pushed outward by the airbag 304, and the elastic rod 1002 supports the airbag 304, which facilitates the stable removal of the explosive from the borehole. After the explosive is loaded, when it is necessary to remove the feed rod 102 from the borehole, the elastic rod 1002 is elastic and can be bent into a near-horizontal state under the squeezing action of the edge of the feed rod 102, so as to retract into the interior of the feed rod 102. When the screw feed mechanism 104 drives the feed rod 102 to move out, it avoids the elastic rod 1002 from contacting the explosive and causing obstruction to the feed rod 102.

[0034] In some embodiments, the deep-hole blasting continuous pushing charging machine in coal mines further includes a turning mechanism. The turning mechanism includes a fixed platform 801, a receiving cylinder 802, and an opening and closing component. The fixed platform 801 is connected to the charging cylinder 101, and the receiving cylinder 802 is pivotally connected to the fixed platform 801. The first end of the receiving cylinder 802 is inclined toward the fixed platform 801, and the opening and closing component is located at the first end of the receiving cylinder 802 to open and close the receiving cylinder 802.

[0035] Specifically, such as Figure 11As shown, a fixed platform 801 is mounted on the delivery cylinder 101, and a receiving cylinder 802 is inclinedly mounted on the fixed platform 801. A rotating shaft is rotatably mounted on the top of the fixed platform 801, and the receiving cylinder 802 is fixed to the rotating shaft. An opening and closing assembly is used to open and close the side of the receiving cylinder 802 with its lower height relative to the upper surface of the fixed platform 801. The fixed platform 801 is located in the middle of the delivery cylinder 101, and the receiving cylinder 802 can rotate around the rotating shaft. Explosives or detonators pass through... The discharge port and the drop port fall on the receiving cylinder 802. Since the receiving cylinder 802 is set at an inclination, the explosive or detonator slides to the lower side of the receiving cylinder 802 under the action of gravity. The opening and closing device blocks the explosive or detonator. The opening and closing device is controlled to open and close the receiving cylinder 802, so that the explosive or detonator slides down the receiving cylinder 802 into the inside of the delivery cylinder 101. The receiving cylinder 802 can rotate 180 degrees, so the direction of the explosive or detonator can be adjusted and the detonation direction can be changed.

[0036] In some embodiments, the opening and closing element includes an opening and closing plate 901, a driving gear 903, and a driven gear 904. The opening and closing plate 901 is pivotally connected to the first end of the receiving cylinder 802. The driven gear 904 is disposed on the opening and closing plate 901. A motor 902 is disposed on the receiving cylinder 802. The driving gear 903 is disposed on the output end of the motor 902. The driving gear 903 meshes with the driven gear 904.

[0037] Specifically, such as Figure 11 As shown, the opening and closing component includes an opening and closing plate 901, which is disposed on the lower side of the receiving cylinder 802 and rotatably connected to the receiving cylinder 802. A rotating rod is rotatably disposed on one side of the receiving cylinder 802. The opening and closing plate 901 is fixedly connected to the rotating rod and can rotate relative to the receiving cylinder 802 about the rotating rod as an axis. The opening and closing plate 901 has at least a first position and a second position. In the first position, the opening and closing plate 901 closes the opening on the lower side of the receiving cylinder 802. In the second position, the opening and closing plate 901 is away from the receiving cylinder 802 so that the opening of the receiving cylinder 802 is completely open. A motor 902 is fixed on the receiving cylinder 802. A drive gear 903 is disposed at the output end of the motor 902. A driven gear 904 is concentrically disposed on the rotating rod. The driven gear 904 and the drive gear 903 mesh. The rotation of the motor 902 drives the drive gear 903 to rotate. The drive gear 903 drives the driven gear 904 and thus drives the rotating rod to rotate. As the rotating rod rotates, the opening and closing plate 901 rotates relative to the receiving cylinder 802. Understandably, the rotation direction of the motor 902 can be changed, which in turn changes the rotation direction of the rotating rod, thereby realizing the reciprocating motion of the opening and closing plate 901 between the first and second positions.

[0038] In some embodiments, the deep-hole blasting continuous pushing charging machine in coal mines further includes a wire-sorting mechanism. The wire-sorting mechanism includes a wire-feeding roller 701, a rotating seat 702, a clamping seat 703, and a pressing seat 704. The wire-feeding roller 701 has rotating plates 706 at both ends and is pivotally connected to the rotating plates 706. The end of the rotating plate 706 away from the wire-feeding roller is connected to the charging cylinder 101. The pressing seat 704 is provided with a pressure ball 705. The first end of the pressing seat 704 is provided with a rotating seat 702, which is pivotally connected to the rotating plate 706 at one end of the wire-feeding roller 701. The second end of the pressing seat 704 is provided with a clamping seat 703, which is detachably connected to the rotating plate 706 at the other end of the wire-feeding roller 701. The end of the pressing seat 704 is connected to the clamping seat 703 or the rotating seat 702 through an elastic element. The clamping seat 703 is provided with a clamping block 707.

[0039] Specifically, such as Figure 9 and Figure 10 As shown, the wire feeding mechanism is used to limit the detonator lead wire. The delivery cylinder 101 has two rotating plates 706. The wire feeding roller 701 is rotatably positioned between the two rotating plates 706. A rotating base 702 is mounted on one of the two rotating plates 706 and rotatably connected to it. A locking block 707 is mounted on a locking seat 703. The rotating plate 706 furthest from the rotating base 702 has a slot that matches the locking block 707. A pressing seat 704 is mounted on the rotating base 702 and the locking seat 703 respectively via a pressing spring and a telescopic rod. A pressure ball 705 is rotatably mounted on the pressing seat 704 and contacts the wire feeding roller 701. Through the rotational cooperation of the rotating base 702 and the rotating plate 706, the pressure ball 705 and the wire feeding roller... The opening and closing mechanism between 701 is achieved. When loading the detonator, the pressure ball 705 is rotated upward to separate it from the wire feeding roller 701, and the lead wire on the detonator is placed on the wire feeding roller 701. The pressure ball 705 is rotated to make the clamping seat 703 clamp onto the rotating plate 706, and the clamping block 707 is clamped into the inside of the clamping groove to ensure the stability of the clamping seat 703 and the rotating seat 702. The pressure ball 705 presses the lead wire tightly onto the surface of the wire feeding roller 701. When pushing the detonator in, the wire feeding roller 701 and the pressure ball 705 work together to limit the lead wire. The rotation of the wire feeding roller 701 and the pressure ball 705 allows the lead wire to enter the blast hole with the detonator, ensuring the tension of the lead wire when entering the blast hole, while ensuring that the part of the lead wire away from the detonator is located outside the blast hole, which facilitates the subsequent mud sealing of the blast hole and detonation.

[0040] In some embodiments, the machine body 1 is connected to the lifting platform 2 via a first electric cylinder 3, and the first electric cylinder 3 is used to drive the lifting platform 2 to move up and down. A second electric cylinder 403 is provided at the end of the medicine delivery cylinder 101 away from the lifting platform 2. The telescopic end of the second electric cylinder 403 is connected to the push plate 401 to drive the push plate 401 to move along the axial direction of the medicine delivery cylinder 101. A third electric cylinder 504 is provided on the support frame 501. The telescopic end of the third electric cylinder 504 is connected to the explosive box 502 or the detonator box 503 to drive the explosive box 502 and the detonator box 503 to move relative to the support frame 501. Both the explosive box 502 and the detonator box 503 are equipped with a fourth electric cylinder 603. The fourth electric cylinder 603 is located at one end of the explosive box 502 or the detonator box 503 near the material discharge port. The telescopic end of the fourth electric cylinder 603 is connected to the baffle block 602 to drive the baffle block 602 to rise and fall.

[0041] Specifically, the machine body 1 is equipped with multiple first electric cylinders 3, and the lifting platform 2 is located at the output end of the first electric cylinders 3. The switches of the multiple first electric cylinders 3 can be set to one, so as to realize the synchronous start and stop of the multiple first electric cylinders 3. The first electric cylinders 3 can drive the lifting platform 2 to move up and down, so that the explosive feeding mechanism moves to the position corresponding to the height of the blast hole. The output end of the second electric cylinder 403 is equipped with a push plate 401. The second electric cylinder 403 can drive the push plate 401 to move, pressing the explosive onto the surface of the airbag 304, or pressing the subsequent explosive onto the surface of the previous explosive, so that the multiple explosives are close to each other. The pressure sensor 402 judges the pressure between the push plate 401 and the explosive, and presets a value to make the explosive and the airbag 304 or two adjacent explosives close but not too close. After reaching the value, the second electric cylinder 403 drives the push plate 401 to move back to the original position, so that the subsequent explosive falls between the push plate 401 and the previous explosive. The output end of the third electric cylinder 504 is connected to the explosive box 502 or the detonator box 503. The third electric cylinder 504 can drive the explosive box 502 and the detonator box 503 to move. When the discharge port and the drop port of the explosive box 502 or the detonator box 503 are aligned, the explosives or detonators in the explosive box 502 or the detonator box 503 can fall through the discharge port and the drop port to complete the discharge. The fourth electric cylinder 603 can drive the baffle block 602 to rise and fall, separating the explosives (or detonators) at the discharge port from the adjacent explosives (or detonators).

[0042] In some embodiments, the support mechanism further includes a push-pull rod 1004 and a sixth electric cylinder. The first end of the push-pull rod 1004 is connected to the movable seat 1001, and the sixth electric cylinder is located on the drug delivery cylinder 101. The sixth electric cylinder is connected to the second end of the push-pull rod 1004 to push the movable seat 1001 to move within the drug delivery rod 102.

[0043] Specifically, the output end of the electric cylinder 1003 is equipped with a movable plate, which is connected to two push-pull rods 1004. The electric cylinder 1003 drives the movable plate and push-pull rods 1004 to move, so that the movable seat 1001 moves closer to the air bag 304, and the elastic rod 1002 moves out of the inside of the delivery rod 102. After the charge is loaded, when it is necessary to remove the delivery rod 102 from the borehole, the electric cylinder 1003 drives the movable seat 1001 to move away from the air bag 304, so that the elastic rod 1002 is pulled back into the inside of the delivery rod 102.

[0044] In some embodiments, a driven gear 805 is provided at the bottom of the receiving cylinder 802, and a fifth electric cylinder 803 is provided on the fixed platform 801. The telescopic end of the fifth electric cylinder 803 is connected to the drive rack 804. The drive rack 804 meshes with the driven gear 805. The fifth electric cylinder 803 is used to drive the drive rack 804 to move in a linear direction relative to the fixed platform 801.

[0045] Specifically, such as Figure 11 As shown, a fifth electric cylinder 803 is installed on the fixed platform 801. A drive rack 804 is installed at the output end of the fifth electric cylinder 803, and a driven gear 805 is concentrically installed on the rotating shaft. The driven gear 805 and the drive rack 804 mesh. The fifth electric cylinder 803 can drive the drive rack 804 to move, thereby driving the driven gear 805 and the rotating shaft to rotate, so that the receiving cylinder 802 can rotate 180 degrees.

[0046] In some embodiments, the support mechanism further includes a locking member, which includes a locking plate 201 and a seventh electric cylinder 202. The locking plate 201 is driven by the seventh electric cylinder 202 to abut against the drug delivery cylinder 101, and the locking plate 201 is provided with anti-slip texture.

[0047] Specifically, such as Figure 12 As shown, the locking plate 201 is movably mounted on the lifting platform 2. The locking plate 201 contacts the ball joint 103. The locking plate 201 is provided with anti-slip texture. The lifting platform 2 is provided with a seventh electric cylinder 202. The locking plate 201 is located at the output end of the seventh electric cylinder 202. When the feed rod 102 is inserted into the blast hole, the feed rod 102 is matched with the angle of the blast hole under the limiting action of the blast hole. At the same time, the feed rod 102 drives the feed cylinder 101 to rotate to a state that matches the angle of the blast hole. At this time, the seventh electric cylinder 202 drives the locking plate 201 to press against the surface of the ball joint 103, locking the ball joint 103 and the feed cylinder, ensuring the stability of the feed cylinder and making it correspond to the angle of the blast hole.
