Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically to a jaw crusher with an adjustable discharge port. Background Technology

[0002] Waste metal drums (including paint drums, coating drums, acetone drums, and other discarded iron drums containing or contaminated with toxic or infectious hazardous waste) generated during industrial production cannot be directly discarded and must be properly disposed of to avoid unnecessary waste of resources, environmental damage, and safety hazards. The process requires high-quality waste drums, mainly for refurbishment and reuse. Furthermore, the process generates a large amount of industrial wastewater, which is classified as hazardous waste, incurring extremely high treatment costs, and improper handling can pollute local water resources. In response, our company has developed a dry treatment process for waste metal drums. During the entire process, no wastewater is generated, and the exhaust gas is treated by a treatment device to meet emission standards.

[0003] In existing technologies, preliminary crushing of waste metal drums often requires initial processing using a jaw crusher. However, the discharge port of existing jaw crushers is relatively fixed and cannot be adjusted. This results in the inability to process different types of waste metal drums, affecting the processing efficiency of waste metal drums. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a jaw crusher with an adjustable discharge port to solve the technical problem that the discharge port of the jaw crusher is relatively fixed and cannot be adjusted, which leads to the inability to process different waste metal barrels and affects the processing efficiency of waste metal barrels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jaw crusher with an adjustable discharge port, comprising a main body, a first motor disposed at the top of the main body, a pulley disposed at the output end of the first motor, a belt disposed on the outside of the pulley, a fixed cylinder movably connected inside the main body, a movable jaw fixed at the bottom end of the fixed cylinder, a cam rod movably connected inside the fixed cylinder, limit wheels disposed at both ends of the cam rod, a second motor disposed inside the main body, a lead screw disposed at the output end of the second motor, a fixed jaw movably connected inside the main body, and two sets of hydraulic rods disposed inside the main body.

[0006] By adopting the above technical solution, when in use, after connecting the power supply, the external staff first put the waste metal barrel that needs to be crushed into the gap between the fixed jaw and the moving jaw set inside the main body. Then, the external staff start the first motor through the control device. When the first motor rotates, it will drive the pulley fixed to its outer output end to rotate.

[0007] When the pulley rotates, it transmits the dynamic force to the limit wheel through the belt. The limit wheel rotates at high speed, causing the cam rod fixed at one end of the limit wheel to rotate at high speed. The rotation of the cam rod causes the fixed cylinder on its outer side to drive the moving jaw at its bottom end to vibrate in a certain regular manner.

[0008] This shaking causes the external scrap metal barrel to move into the body, and the squeezing of the moving jaw and the fixed jaw causes the scrap metal barrel to be crushed, thereby achieving the initial crushing effect.

[0009] When breaking large metal drums, external personnel need to start the second motor through an external control device. When the second motor starts, its output end will rotate at high speed, and the second toothed pulley set on the outside of the output end will also rotate at high speed synchronously.

[0010] The force is transmitted to the first toothed pulley through the toothed chain belt connected to the outside of the second toothed pulley, thereby achieving synchronous high-speed rotation of the two sets of lead screws.

[0011] When the two sets of lead screws rotate at high speed, the fixed jaw that meshes with the outer thread will move along the multiple sets of sliding grooves set inside the main body. By moving the fixed jaw, the feed inlet and discharge outlet can be adjusted, making it easier for external workers to crush more waste metal barrels of different sizes.

[0012] Specifically, this process mainly utilizes the high temperature of approximately -℃ generated during the two-stage crushing process to peel off harmful substances such as paint and attachments from the outer wall of the waste iron drum. After being separated from the iron by a screening machine, the waste iron is collected and sent to a qualified manufacturer for processing. At the same time, the harmful substances inside the drum are vaporized and evaporated, and then treated and collected by subsequent waste gas treatment devices. No waste gas or wastewater is generated during the production process.

[0013] Through the above structure, the jaw crusher can adjust the discharge port according to the usage conditions, which is convenient for processing waste metal drums of different sizes and specifications, and improves the processing efficiency of waste metal drums.

[0014] Furthermore, a ball shaft is fixed to one end of the hydraulic rod, and two sets of limiting sleeves that cooperate with the ball shaft are provided at one end of the movable jaw.

[0015] By adopting the above technical solution, the cooperation between the ball shaft and the limiting sleeve ensures that the hydraulic rod will not wobble while pushing the adjusting jaw.

[0016] Furthermore, the limiting wheel is connected to the pulley via a belt, and the first motor is fixed to the top of the main body by screws.

[0017] By adopting the above technical solution, the limit wheel can rotate synchronously with the pulley via the belt, thereby improving efficiency.

[0018] Furthermore, a second toothed pulley is provided on the outer side of the lead screw, and the second toothed pulley is provided with a toothed chain belt.

[0019] By adopting the above technical solution, the force that causes the lead screw to rotate via the second toothed pulley can be synchronously transmitted to another set of lead screws via the toothed chain belt.

[0020] Furthermore, the second toothed pulley is connected to the first toothed pulley via a toothed chain belt drive, and a fixing plate that cooperates with the hydraulic rod is provided inside the main body.

[0021] By adopting the above technical solution, the meshing of the toothed belt ensures that the second toothed pulley and the first toothed pulley can rotate synchronously, preventing slippage.

[0022] Furthermore, a lead screw sleeve that cooperates with the lead screw is provided at one end of the fixed jaw, and a cavity that cooperates with the lead screw is opened inside the fixed jaw.

[0023] By adopting the above technical solution, the lead screw sleeve can effectively limit the rotation of the lead screw, preventing the adjustable size from being limited due to the stroke.

[0024] In summary, the present invention has the following beneficial effects: When a waste metal barrel enters the opening between the fixed jaw and the moving jaw, the rotation of the first motor transmits its power through a belt to the limiting wheel. The cam rod fixed to one end of the limiting wheel causes the moving jaw to vibrate. This vibration causes the waste metal barrel to move slowly downwards, being squeezed by the moving jaw. When crushing larger metal barrels, the second motor can be activated to rotate the two sets of lead screws, causing the fixed block on the outside of the fixed jaw to move along the sliding groove inside the main body. This allows for adjustment of the size of the discharge port and the feed port. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] A jaw crusher with an adjustable discharge port, such as Figures 1-5 As shown, the device includes a main body 1, a first motor 2 at the top of the main body 1, a pulley 3 at the output end of the first motor 2, a belt 4 on the outside of the pulley 3, and a fixed cylinder 5 movably connected inside the main body 1. In use, when the power is turned on, the external personnel first put the waste metal barrel to be crushed into the gap between the fixed jaw 9 and the movable jaw 7 inside the main body 1. Then, the external personnel start the first motor 2 through the control device. When the first motor 2 rotates, it will drive the pulley 3 fixed at its output end to rotate.

[0034] For example, a movable jaw 7 is fixed at the bottom of the fixed cylinder 5, and a cam rod 18 is movably connected inside the fixed cylinder 5. Limiting wheels 6 are provided at both ends of the cam rod 18, and a second motor 8 is provided inside the main body 1. When the pulley 3 rotates, it transmits the dynamic force to the limiting wheel through the belt 4, and the limiting wheel 6 rotates at high speed, so that the cam rod 18 fixed at one end of the limiting wheel 6 rotates at high speed. The rotation of the cam rod 18 causes the fixed cylinder 5 on the outside to drive the movable jaw 7 at its bottom end to vibrate in a certain regular manner.

[0035] For example, the output end of the second motor 8 is provided with a lead screw 12, the main body 1 is movably connected with a fixed jaw 9, the main body 1 is provided with two sets of hydraulic rods 19, one end of the hydraulic rod 19 is fixed with a ball shaft 16, the movable jaw 7 is provided with two sets of limiting sleeves 17 that cooperate with the ball shaft 16, and the lead screw 12 is provided with a second toothed pulley 14. Through this vibration, the external waste metal barrel is moved into the main body 1, and the waste metal barrel is crushed by the squeezing of the movable jaw 7 and the fixed jaw 9, so as to achieve the initial crushing effect. When a larger metal barrel needs to be crushed, the external staff needs to start the second motor 8 through an external control device. When the second motor 8 is started, its output end will rotate at high speed, and the second toothed pulley 14 provided on the outside of the output end will also rotate at high speed synchronously.

[0036] For example, the second toothed pulley 14 is provided with a toothed chain belt 15, and the second toothed pulley 14 is connected to the first toothed pulley 13 through the toothed chain belt 15. The main body 1 is provided with a fixed plate that cooperates with the hydraulic rod 19. One end of the fixed jaw 9 is provided with a screw sleeve 11 that cooperates with the screw 12. The fixed jaw 9 has a cavity that cooperates with the screw 12. When the two sets of screws 12 rotate at high speed, the fixed jaw 9 that meshes with the outer thread of the screw 12 will move along the multiple sets of sliding grooves 10 provided inside the main body 1. By moving the fixed jaw 9, the feed inlet and the discharge outlet can be adjusted, which makes it convenient for external personnel to crush more waste metal barrels of different sizes.

[0037] The working principle of this utility model is as follows: When in use, the power is turned on, and the external staff first put the waste metal barrel that needs to be crushed into the gap between the fixed jaw 9 and the moving jaw 7 set inside the main body 1. Then the external staff start the first motor 2 through the control device. When the first motor 2 rotates, it will drive the pulley 3 fixed to its outer output end to rotate.

[0038] When the pulley 3 rotates, it transmits the dynamic force to the limit wheel through the belt 4, and the limit wheel 6 rotates at high speed, causing the cam rod 18 fixed at one end of the limit wheel 6 to rotate at high speed. The rotation of the cam rod 18 causes the fixed cylinder 5 on its outer side to drive the moving jaw 7 at its bottom end to vibrate in a certain regular manner.

[0039] This shaking causes the external waste metal barrel to move into the body 1, and the squeezing of the moving jaw 7 and the fixed jaw 9 causes the waste metal barrel to be crushed, thereby achieving the initial crushing effect.

[0040] When breaking large metal drums, external personnel need to start the second motor 8 through an external control device. When the second motor 8 starts, its output end will rotate at high speed, and the second toothed pulley 14 set on the outside of the output end will also rotate at high speed synchronously.

[0041] The force is transmitted to the first toothed pulley 13 through the toothed chain belt 15 connected to the outside of the second toothed pulley 14, thereby realizing the synchronous high-speed rotation of the two sets of lead screws 12.

[0042] When the two sets of lead screws 12 rotate at high speed, the fixed jaw 9, which meshes with the outer thread of the screw, moves along the multiple sets of sliding grooves 10 set inside the main body 1. The movement of the fixed jaw 9 is used to adjust the feed inlet and the discharge outlet, making it easier for external staff to crush more waste metal barrels of different sizes.

[0043] Specifically, this process mainly utilizes the high temperature (approximately 200-300℃) generated during the two-stage crushing process to peel off harmful substances such as paint and attachments from the outer wall of the waste iron drum. After being separated from the iron by a screening machine, the waste iron is collected and sent to a qualified manufacturer for processing. At the same time, the harmful substances inside the drum are vaporized and evaporated, and then treated and collected by subsequent waste gas treatment devices. No waste gas or wastewater is generated during the production process.

[0044] Through the above structure, the jaw crusher can adjust the discharge port according to the usage conditions, which is convenient for processing waste metal drums of different sizes and specifications, and improves the processing efficiency of waste metal drums.
