Description

Technical Field

[0001] This utility model relates to the field of lead-zinc ore crushing technology, specifically an adjustable lead-zinc ore jaw crusher. Background Technology

[0002] Lead-zinc ore is a mineral rich in the metallic elements lead and zinc, mainly existing in the form of sulfides, such as galena and sphalerite.

[0003] In actual use, most existing jaw crushers transport lead-zinc ore into the equipment via conveyor belts. However, the conveyor belt's feeding speed is uncontrollable, leading to excessive material accumulation inside the equipment. Consequently, if the equipment cannot handle the material in time, the material will accumulate to an excessive height and overflow from the equipment. At the same time, the distance between the jaw plates cannot be adjusted, which limits the crushing effect. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustable jaw crusher for lead-zinc ore, which has the advantages of preventing material accumulation and adjusting the jaw plate spacing, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: an adjustable lead-zinc ore jaw crusher, including a fixed shell, a hopper fixedly installed on the top of the fixed shell, a conveyor belt fixedly installed on the outer wall of the hopper, an extension shell fixedly installed on the outer wall of the fixed shell, a fixed column fixedly installed on the outer wall of the fixed shell, a pressure plate slidably connected to the inner wall of the fixed column, a spherical head fixedly installed on the outer wall of the pressure plate, a spring provided on the inner wall of the fixed column, a pressure sensor fixedly installed on the inner wall of the fixed column, and jaw plate one and jaw plate two slidably connected to the inner wall of the fixed shell respectively. A rack one is fixedly installed on the outer wall of jaw plate two. A rotating shaft is rotatably connected to the inner wall of the extended shell. A gear and a worm gear are fixedly sleeved on the outer wall of the rotating shaft. A motor is fixedly installed on the outer wall of the extended shell. A worm gear is fixedly installed on the output shaft of the motor. A motor is fixedly installed on the outer wall of the fixed shell. A motor is fixedly installed on the outer wall of the hopper. A double-ended lead screw is fixedly installed on the output shaft of the motor. A rack is slidably connected to the outer wall of the hopper. A gear is rotatably connected to the outer wall of the hopper. A sliding rod is fixedly installed on the outer wall of the hopper. A rotating plate is rotatably connected to the inner wall of the hopper. A connecting column is fixedly installed on the outer wall of the rotating plate.

[0006] As a preferred technical solution of this utility model: the first gear is located above the first rack, and the first gear meshes with the first rack.

[0007] As a preferred technical solution of this utility model: the worm is located above the worm wheel, and the worm meshes with the worm wheel.

[0008] As a preferred technical solution of this utility model: the slide rod and the double-ended lead screw pass through the rack two, and the slide rod is slidably connected to the rack two, and the double-ended lead screw is threadedly connected to the rack two.

[0009] As a preferred technical solution of this utility model: the number of gear 2, rack 2, slide rod, connecting column and rotating plate is two, and the two gear 2, rack 2, slide rod, connecting column and rotating plate are symmetrically arranged. The two racks 2 are located at both ends of the double-ended lead screw, and the two racks 2 mesh with the two gear 2.

[0010] As a preferred technical solution of this utility model: the trigger head of the pressure sensor is attached to the outer wall of the pressure plate, and the pressure sensor and the motor are electrically connected.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This adjustable lead-zinc ore jaw crusher works by accumulating material between jaw plate one and jaw plate two. When the material accumulation reaches the outside of the spherical head, the material squeezes the spherical head, causing the spherical head to move the pressure plate. This causes the pressure plate to trigger the pressure sensor, which then sends an electrical signal to motor three. This causes motor three to drive the double-headed screw to rotate, which in turn drives the two racks two to move. The two racks two drive the two gears two to rotate, which in turn drives the two rotating plates to rotate. This causes the two rotating plates to close, thus blocking the material transmission from the hopper to the inside of the fixed shell, preventing excessive material accumulation inside the fixed shell.

[0013] 2. This adjustable lead-zinc ore jaw crusher, by starting motor one, causes motor one to drive the worm to rotate. The worm gear meshes with the worm wheel, causing the worm wheel to rotate. The worm wheel drives gear one to rotate through the rotating shaft. Gear one meshes with rack one, causing rack one to move. Rack one then drives jaw plate two to move, thereby adjusting the distance between jaw plate two and jaw plate one. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 5 An adjustable lead-zinc ore jaw crusher includes a fixed shell 1, a hopper 2 fixedly mounted on the top of the fixed shell 1, a conveyor belt 3 fixedly mounted on the outer wall of the hopper 2, an extension shell 4 fixedly mounted on the outer wall of the fixed shell 1, a fixed column 5 fixedly mounted on the outer wall of the fixed shell 1, a pressure plate 7 slidably connected to the inner wall of the fixed column 5, a spherical head 6 fixedly mounted on the outer wall of the pressure plate 7, a spring 8 provided on the inner wall of the fixed column 5, a pressure sensor 9 fixedly mounted on the inner wall of the fixed column 5, jaw plates 10 and 11 slidably connected to the inner wall of the fixed shell 1, a rack 12 fixedly mounted on the outer wall of the second jaw plate 11, and a rotating mechanism rotatably connected to the inner wall of the extension shell 4. The outer walls of the rotating shaft 25 are respectively fixedly fitted with gear 13 and worm gear 16. The outer wall of the extended housing 4 is fixedly installed with motor 14. The output shaft of motor 14 is fixedly installed with worm gear 15. The outer wall of the fixed housing 1 is fixedly installed with motor 27. The outer wall of the hopper 2 is fixedly installed with motor 34. The output shaft of motor 324 is fixedly installed with double-headed screw 18. The outer wall of the hopper 2 is slidably connected with rack 20. The outer wall of the hopper 2 is rotatably connected with gear 29. The outer wall of the hopper 2 is fixedly installed with slide rod 21. The inner wall of the hopper 2 is rotatably connected with rotating plate 23. The outer wall of rotating plate 23 is fixedly installed with connecting column 22.

[0022] In the above structure, lead-zinc ore is transported towards hopper 2 by conveyor belt 3. When the lead-zinc ore reaches the top of conveyor belt 3, it falls into the interior of hopper 2. At this time, the lead-zinc ore is discharged from the interior of hopper 2 and enters the interior of fixed shell 1 by controlling the opening and closing of rotating plate 23.

[0023] In a preferred embodiment, gear 13 is located above rack 12 and meshes with rack 12.

[0024] In the above structure, by rotating the rotating shaft 25, the rotating shaft 25 drives the gear 13 to rotate. The gear 13 meshes with the rack 12, causing the rack 12 to move on the inner wall of the extended housing 4. This causes the rack 12 to pull the jaw plate 11 to move, thus changing the position of the jaw plate 11 on the inner wall of the fixed housing 1. At this time, the distance between the jaw plate 11 and the jaw plate 10 changes.

[0025] In a preferred embodiment, the worm 15 is located above the worm wheel 16, and the worm 15 meshes with the worm wheel 16.

[0026] In the above structure, by starting the motor 14, the motor 14 drives the worm 15 to move. The worm 15 meshes with the worm wheel 16, causing the worm wheel 16 to rotate. The worm wheel 16 then drives the rotating shaft 25 to rotate, which in turn drives the gear 13 to rotate.

[0027] In a preferred embodiment: the slide rod 21 and the double-ended lead screw 18 pass through the rack 20, and the slide rod 21 is slidably connected to the rack 20, and the double-ended lead screw 18 is threadedly connected to the rack 20.

[0028] In the above structure, by starting the motor 3 24, the motor 3 24 drives the double-ended lead screw 18 to rotate. At this time, the double-ended lead screw 18 and the rack 2 20 are connected by a thread to move the rack 2 20. The rack 2 20 is limited by the slide rod 21, so that the rack 2 20 can only slide on the outer wall of the slide rod 21 when it moves.

[0029] In a preferred embodiment, there are two gears 19, two racks 20, two slide rods 21, two connecting columns 22 and two rotating plates 23, and the two gears 19, two racks 20, two slide rods 21, two connecting columns 22 and rotating plates 23 are symmetrically arranged. The two racks 20 are located at both ends of the double-ended lead screw 18, and the two racks 20 mesh with the two gears 19.

[0030] In the above structure, by starting the motor 24, the motor 24 drives the double-ended lead screw 18 to move, the double-ended lead screw 18 drives the two racks 20 to move, and the two racks 20 drive the two gears 29 to rotate through meshing with the two gears 29, and the two gears 29 drive the rotating plate 23 to rotate through the connecting column 22, thereby causing the rotating plate 23 to open and close.

[0031] In a preferred embodiment: the trigger head of the pressure sensor 9 is attached to the outer wall of the pressure plate 7, and the pressure sensor 9 is electrically connected to the motor 24.

[0032] In the above structure, when the height of the lead-zinc ore accumulation inside the fixed shell 1 reaches the outer wall of the spherical head 6, the weight of the lead-zinc ore presses the spherical head 6 toward the fixed column 5, thereby causing the fixed column 5 to drive the pressure plate 7 to move toward the pressure sensor 9, so that the trigger head of the pressure sensor 9 is pressed. At this time, the pressure sensor 9 is triggered to send an electrical signal to the motor 24, causing the motor 24 to start.

[0033] Working Principle: When using this equipment, the conveyor belt 3 transports lead-zinc ore towards the hopper 2. When the lead-zinc ore reaches the top of the conveyor belt 3, it falls into the hopper 2. At this time, the opening and closing of the rotating plates 23 discharges the lead-zinc ore into the hopper 2. At this time, the two rotating plates 23 are in the open state, allowing the material to enter the fixed shell 1 through the rotating plates 23. Then, the starting of the second motor 17 drives the jaw plate 10 to vibrate, causing the lead-zinc ore between the jaw plate 10 and the second jaw plate 11 to be crushed. The material then falls downward to the bottom of the equipment. When the material accumulation height between the jaw plate 10 and the second jaw plate 11 reaches the outer wall of the spherical head 6, the weight of the lead-zinc ore presses the spherical head 6 towards the fixed column 5, which in turn causes the fixed column 5 to move the pressure plate 7 towards the pressure sensor 9, causing the trigger head of the pressure sensor 9 to be pressed. At this time, the pressure sensor 9 is triggered and sends an electrical signal to the third motor 24, causing the third motor 24 to start. When the motor 24 drives the double-ended lead screw 18 to move, the double-ended lead screw 18 drives the two racks 20 to move, and the two racks 20 drive the two gears 29 to rotate through meshing with the two gears 29. The two gears 29 then drive the rotating plate 23 to rotate through the connecting column 22, causing the two rotating plates 23 to close and block the feed to prevent excessive material accumulation, which could lead to the jaw plates 10 and 21 not processing in time and thus causing material overflow. When it is necessary to adjust the distance between the jaw plates 10 and 21, the motor 14 is started, which drives the worm 15 to rotate. The worm 15 drives the worm wheel 16 to rotate, the worm wheel 16 drives the rotating shaft 25 to rotate, and the rotating shaft 25 drives the gear 13 to rotate. The gear 13 drives the rack 12 to move, which in turn drives the jaw plate 21 to move, thereby adjusting the distance between the jaw plates 10 and 21.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
