Description

Technical Field

[0001] The invention relates to the technical field of mining machinery accessories, in particular to a feeding hopper for mining machinery. Background Art

[0002] Mining machinery is machinery directly used for mineral mining and enrichment, including mining machinery and mineral processing machinery. After mining, mining machinery will immediately transfer the minerals to the feed hopper for crushing and screening. Ore crusher is a type of mining machinery. Ore crusher generally adds materials from the feed hopper. Since the existing feed hopper structure is mostly open, when the material inside the mining machinery is crushed, a lot of dust will be generated, which will escape directly from the discharge hopper, causing environmental pollution.

[0003] The existing patent (publication number: CN113617502B) discloses a feed hopper structure for mining machinery, including a device body, including a lower base of the feed hopper, a horizontal cylindrical tube connected to the lower base of the feed hopper, and a support opening and closing component arranged in the horizontal cylindrical tube; the support opening and closing component includes an automatic opening and closing part, and a counterweight support resistance reducing part connected to the automatic opening and closing part. The beneficial effects of the present invention are to realize automatic opening and closing without manual operation by the staff, easy to use, time-saving and labor-saving, good dust-proof effect, ensure the stability of the device and not easy to damage, reduce the resistance inside the device, and extend the service life of each accessory.

[0004] The above patented technology utilizes a rotating sealing plate to block dust and prevent dust from escaping from the upper seat of the feed hopper and causing environmental pollution. However, in actual use, the sealing plate is rotated by utilizing the gravity of the ore. The main axis of the rotation point of the sealing plate is located at the center of the feed hopper. However, when the ore enters the feed hopper and accumulates at the main axis of the feed hopper, the force on both sides of the sealing plate is uniform, which may not cause the sealing plate to rotate at the rotation point of the main axis. Moreover, when the sealing plate rotates, if the ore is large, the ore above the sealing plate may be stuck to the inner wall of the feed hopper, resulting in the ore being unable to fall from the feed hopper, causing the feed hopper to be blocked. The possibility of blockage is relatively high, and after blockage, it needs to be manually unblocked, which makes the working efficiency of the mining machinery low.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0035] Please refer to Figure 1-Figure 7The present invention provides a technical solution: a feed hopper for mining machinery, comprising a feed hopper body 1, the feed hopper body 1 is funnel-shaped, the left and right outer surfaces of the feed hopper body 1 are fixedly connected with a first accommodating box, the front and rear opposite inner surfaces of the two first accommodating boxes are rotatably connected with a rotating shaft 2, the outer surfaces of the two rotating shafts 2 are fixedly sleeved with two rotating seats 3, the opposite outer surfaces of the two left rotating seats 3 and the two right rotating seats 3 are fixedly connected with a closing plate 4, the two closing plates 4 do not fit each other, the front and rear outer surfaces of the feed hopper body 1 are fixedly connected with a second accommodating box, the top inner surface of the second accommodating box is fixedly connected with two elastic ropes 5, the front and rear outer surfaces of the two closing plates 4 are fixedly connected with a supporting seat 6, the top outer surface of the supporting seat 6 is fixedly connected with a fixing ear 7, and the other ends of the four elastic ropes 5 are respectively fixedly connected to the four fixing ears 7. The ore is transported to the inside of the feed hopper body 1, and the ore falls onto the closing plate 4. Due to the action of its own gravity, the closing plate 4 drives the rotating seat 3 to rotate the rotating shaft 2. Since there is a certain gap between the two closing plates 4, one end of the two closing plates 4 can move downward to stretch the elastic rope 5, so that the ore falls. The rotation axis of the closing plate 4 is located on both sides. When the ore is accumulated on the closing plate 4, the closing plate 4 can be tilted due to the action of gravity. After the ore falls in, when there is no ore on the closing plate 4, the elastic rope 5 resets and pulls the closing plate 4 to reset, and performs sealing work to reduce dust discharge from the feed hopper body. The rotating shaft 2 of the closing plate 4 is located on both sides, so it can be tilted and rotated due to the gravity of the ore.

[0036] Two crushing rollers 8 are rotatably connected between the opposite inner surfaces on the left and right sides of the feed hopper body 1, and the left outer surfaces of the two crushing rollers 8 rotate and penetrate the left outer surface of the feed hopper body 1. The outer surfaces of the two crushing rollers 8 located outside the feed hopper body 1 are fixedly sleeved with driving gears 9, and the left outer surface of the feed hopper body 1 is rotatably connected to two rotating shafts, and the left outer surface of the feed hopper body 1 is fixedly connected to a motor frame, and a driving motor 11 is fixedly installed on the outer surface of the motor frame. The driving motor 11 is fixedly connected to the output end of the rotating shaft on the rear side, and the outer surfaces of the two rotating shafts are fixedly sleeved with transmission gears 10, which are meshed with each other, and the two transmission gears 10 are located between the two driving gears 9. The outer surfaces of the two transmission gears 10 are movably meshed with the outer surfaces of the two driving gears 9 respectively. The driving motor 11 drives the rotating shaft on the rear side to rotate, and drives the transmission gear 10 on the rear side to rotate. When the transmission gear 10 on the rear side rotates, it drives another transmission wheel 28 gear to rotate. The rotation directions of the two transmission gears 10 are opposite. The two transmission gears 10 respectively drive the two driving gears 9 to rotate, and the rotation directions of the two driving gears 9 are opposite, so that the two crushing rollers 8 rotate relative to each other to crush larger ores to prevent the feed hopper body 1 from being blocked.

[0037] Two limiting plates are fixedly connected to the top inner surfaces of the two first containing boxes, and the bottom outer surfaces of the two limiting plates are respectively in contact with the four supporting seats 6. The limiting plates limit the supporting seats 6, thereby limiting the closing plate 4. When the supporting seats 6 are in contact with the limiting plates, the elastic rope 5 cannot pull the closing plate 4, so that the closing plate 4 is in a relatively horizontal state.

[0038] The bottom outer surface of the feed hopper body 1 is fixedly connected with a mounting plate 33, the interior of the mounting plate 33 is hollow, and the outer surface of the mounting plate 33 is provided with a plurality of mounting screw holes 34. The mounting plate 33 is installed by screwing the mounting bolts into the corresponding mounting screw holes, and then the feed hopper body 1 is installed at the feed end of the mining machinery.

[0039] In the specific implementation process, the mounting plate 33 is installed by screwing the mounting bolts into the corresponding mounting threaded holes, and then the feed hopper body 1 is installed at the feed end of the mining machinery, and the ore is transported to the inside of the feed hopper body 1, and the drive motor 11 is turned on. The drive motor 11 drives the rotating shaft connected to its output end to rotate, thereby driving the transmission gear 10 thereon to rotate, and then the two transmission gears 10 and the two driving gears 9 rotate. The rotation directions of the two transmission gears 10 are opposite, so that the rotation directions of the two driving gears 9 are opposite, so that the two driving gears 9 rotate in opposite directions, and the two driving gears 9 rotate in opposite directions. The two crushing rollers 8 are driven to rotate in opposite directions, so as to crush the larger ore inside the feed hopper body 1, and the ore falls onto the closing plate 4. Due to the action of its own gravity, the closing plate 4 drives the rotating seat 3 to rotate the rotating shaft 2, and one end of the closing plate 4 moves downward to stretch the elastic rope 5, so that the ore falls. The rotation axis of the closing plate 4 is located on both sides. When the ore is accumulated on the closing plate 4, the closing plate 4 can be tilted due to the action of gravity. When the ore falls in and there is no ore on the closing plate 4, the elastic rope 5 is reset to pull the closing plate 4 to reset, and the sealing work is performed to reduce the discharge of dust from the feed hopper body.

[0040] Embodiment 2: A dust suction pipe 12 is fixedly connected to the upper end of the inner surface of the feed hopper body 1, and a plurality of dust suction nozzles 15 are fixedly connected to the outer surface of the dust suction pipe 12. A dust exhaust box 13 is fixedly connected to the right outer surface of the feed hopper body 1, and an air suction pump 14 is fixedly installed on the top outer surface of the dust exhaust box 13. The input end of the air suction pump 14 is fixedly connected to an air suction pipe 16, and the output end of the air suction pump 14 is fixedly connected to an exhaust pipe 17. One end of the air suction pipe 16 away from the input end of the air suction pump 14 is fixedly connected to the interior of the dust suction pipe 12, and one end of the exhaust pipe 17 away from the output end of the air suction pump 14 is connected to the interior of the dust exhaust box 13. A filter plate 18 is arranged inside the dust exhaust box 13, and a filter screen 19 is arranged inside the filter plate 18. An air outlet is provided on the right outer surface of the dust exhaust box 13.

[0041] The inner surface of the feed hopper body 1 is fixedly connected with a guide plate at the upper end, and the guide plate is tilted inwards and arranged above the dust suction pipe 12. The ore is guided by the guide plate, and the dust suction pipe 12 and the dust suction nozzle 15 are protected to prevent the ore from bumping against the dust suction pipe 12 and the dust suction nozzle 15.

[0042] In the specific implementation process, when the ore enters the interior of the feed hopper body 1, dust will be raised to a certain extent. At this time, the air suction pump 14 works, and the air suction pump 14 absorbs the gas mixed with dust from the dust suction nozzle 15 through the suction pipe 16 and the dust suction pipe 12, and discharges it to the dust exhaust box 13 through the exhaust pipe 17, filters the mixed dust through the filter net 19, and discharges relatively fresh air through the air outlet. Example 2

[0043] Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a hook rod 20 is fixedly sleeved on the outer surface of the right rotating shaft 2, a rectangular groove for accommodating the movement of the hook rod 20 is opened on the outer surface of the right first accommodating box, a movable rod 21 is rotatably connected to the outer surface of the hook rod 20, the movable rod 21 movably penetrates the bottom outer surface of the dust exhaust box 13, a pushing plate 22 is fixedly connected to the top outer surface of the movable rod 21, the diameter of the pushing plate 22 is larger than the diameter of the movable rod 21, a spring 23 is fixedly connected to the bottom outer surface of the pushing plate 22, the bottom outer surface of the spring 23 is fixedly connected to the bottom inner surface of the dust exhaust box 13, the spring 23 is sleeved on the outer surface of the movable rod 21, the inner surface of the dust exhaust box 13 is fixedly connected to a rotating rod 24, and the outer surface of the rotating rod 24 is rotatably sleeved with a toggle rod 25.

[0044] The filter plate 18 is movably inserted into the inner surface of the dust box 13, and the top outer surface of the filter plate 18 is fixedly connected with a fixing plate 30. The top outer surface of the fixing plate 30 is provided with two symmetrically arranged fixing screw holes 31, and the bottom outer surface of the fixing plate 30 is fixedly connected with a sealing gasket. The fixing plate 30 is installed on the top outer surface of the dust box 13 by screwing the fixing bolts into the fixing screw holes 31. When the filter screen 19 needs to be replaced, the fixing bolts are removed, the fixing plate 30 is removed, the filter plate 18 is taken out, the filter screen 19 is replaced, and the sealing between the fixing plate 30 and the dust box 13 is increased by the sealing gasket.

[0045] The inner periphery of the filter plate 18 is fixedly connected with an elastic fiber cloth 32, and the filter screen 19 is fixedly connected to the periphery of the elastic fiber cloth 32. When the toggle rod 25 knocks the filter screen 19, the filter screen 19 can be elastically deformed under the action of the elastic fiber cloth 32, and the filter screen 19 can be reset by the action of the elastic fiber cloth 32.

[0046] In a specific embodiment, after the filter screen 19 is used for a long time, it may be clogged. Therefore, when the closing plate 4 tilts downward, the rotating shaft 2 is driven to rotate, and the rotating shaft 2 drives the hook rod 20 to rotate. When the hook rod 20 rotates, it drives the movable rod 21 to move upward. At this time, the spring 23 is deformed, and the movable rod 21 drives the push plate 22 to make the toggle rod 25 rotate on the rotating rod 24, so that the toggle rod 25 knocks on the filter screen 19 to knock off the dust on it, thereby reducing the possibility of clogging of the filter screen 19. After the spring 23 is deformed, when the closing plate 4 is reset, it drives the push plate 22 to reset, and the toggle rod 25 is reset under the action of the counterweight block. Example 3

[0047] Please refer to Figure 2 , Figure 4 and Fig.11 The present invention provides a technical solution: the inner surface of the feed hopper body 1 is rotatably connected with a diverter rod 26, the left outer surface of the diverter rod 26 rotates and penetrates the left outer surface of the feed hopper body 1, the outer surface of the front crushing roller 8 located outside the feed hopper body 1 and the outer surface of the diverter rod 26 located outside the feed hopper body 1 are both fixedly sleeved with a transmission wheel 28, a belt 29 is wound between the two transmission wheels 28, and the outer surface of the diverter rod 26 is fixedly sleeved with a plurality of diverter plates 27.

[0048] In a specific embodiment, when the crushing roller 8 rotates, the transmission wheel 28 on the crushing roller 8 is driven to rotate, and under the action of the belt 29, the diverter rod 26 is driven to rotate, thereby driving the diverter plate 27 to rotate. The rotation of the diverter plate 27 allows the ore to intermittently enter the interior of the mining machinery, thereby preventing a large amount of ore from entering the mining machinery together and raising a large amount of dust.

[0049] Working principle: When the present invention is used, the mounting plate 33 is installed by screwing the mounting bolts into the corresponding mounting threaded holes, and then the feed hopper body 1 is installed on the feed end of the mining machinery, and the ore is transported to the inside of the feed hopper body 1, and the drive motor 11 is turned on. The drive motor 11 drives the rotating shaft connected to its output end to rotate, thereby driving the transmission gear 10 thereon to rotate, and then the two transmission gears 10 and the two driving gears 9 rotate. The rotation directions of the two transmission gears 10 are opposite, so that the rotation directions of the two driving gears 9 are opposite, so that the two driving gears 9 rotate in opposite directions, and the two driving gears 9 rotate in opposite directions. The wheels 9 drive the two crushing rollers 8 to rotate in opposite directions respectively, so as to crush the larger ore inside the feed hopper body 1, and the ore falls onto the closing plate 4. Due to the action of its own gravity, the closing plate 4 drives the rotating seat 3 to rotate the rotating shaft 2, and one end of the closing plate 4 moves downward to stretch the elastic rope 5, so that the ore falls. The rotation axis of the closing plate 4 is located on both sides. When the ore is accumulated on the closing plate 4, the closing plate 4 can be tilted due to the action of gravity. When the ore falls in and there is no ore on the closing plate 4, the elastic rope 5 resets and pulls the closing plate 4 to reset, thereby sealing and reducing the discharge of dust from the feed hopper body.

[0050] When the ore enters the interior of the feed hopper body 1, dust will be raised to a certain extent. At this time, the air suction pump 14 works, and the air suction pump 14 absorbs the gas mixed with dust from the dust suction nozzle 15 through the suction pipe 16 and the dust suction pipe 12, and discharges it to the dust exhaust box 13 through the exhaust pipe 17, filters the mixed dust through the filter net 19, and discharges relatively fresh air through the air outlet.

[0051] After the filter 19 is used for a long time, it may be clogged. Therefore, when the closing plate 4 tilts downward, the rotating shaft 2 is driven to rotate, and the rotating shaft 2 drives the hook rod 20 to rotate. When the hook rod 20 rotates, it drives the movable rod 21 to move upward. At this time, the spring 23 is deformed, and the movable rod 21 drives the push plate 22 to make the toggle rod 25 rotate on the rotating rod 24, so that the toggle rod 25 knocks on the filter 19 to knock off the dust on it, thereby reducing the possibility of clogging of the filter 19. After the spring 23 is deformed, when the closing plate 4 is reset, it drives the push plate 22 to reset, and the toggle rod 25 is reset under the action of the counterweight block.

[0052] In order to reduce the amount of dust raised by a large amount of ore entering the mining machinery, when the crushing roller 8 rotates, the transmission wheel 28 on the crushing roller 8 is driven to rotate, and under the action of the belt 29, the diverter rod 26 is driven to rotate, thereby driving the diverter plate 27 to rotate. The rotation of the diverter plate 27 allows the ore to intermittently enter the interior of the mining machinery, thereby preventing a large amount of ore from entering the mining machinery and raising a large amount of dust.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
