Description

Technical Field

[0001] This utility model relates to the technical field of toothed roller grading crushers, and more specifically, to a safety protection device for a toothed roller grading crusher. Background Technology

[0002] Toothed roller crushers are equipment used for crushing materials such as ores and coal. Utilizing the special structure and movement of the toothed rollers, the material is subjected to compression, shearing, and tensile forces simultaneously during the crushing process, thereby achieving efficient crushing. At the same time, by rationally designing parameters such as the spacing and rotation speed of the toothed rollers, the crushed material can be classified to meet the particle size requirements of different production processes. Toothed roller crushers are widely used in industries such as mining, coal, and metallurgy.

[0003] A search revealed that Chinese patent CN221868785U discloses a grading toothed roller crusher for coal mines. The first motor on the connecting frame is started, causing the first lead screw to rotate, which in turn causes the moving storage box to lift the raw material. Once the storage box reaches a certain height and is no longer in contact with the baffle, the second motor is started, causing the second lead screw to rotate, allowing the moving raw material to fall from the feed plate into the feed inlet of the grading toothed roller crusher. Simultaneously, the anti-detachment plate prevents the raw material from detaching from the sides of the feed plate when entering the feed inlet.

[0004] When the above-mentioned toothed roller grading crusher is in use, the raw material can be fed into the feed inlet of the grading toothed roller crusher from the feed plate. However, it is difficult to monitor the amount of raw material. When a large amount of raw material floods into the feed inlet in a short period of time, exceeding the processing capacity of the crushing chamber, the accumulation of material will cause the toothed roller rotation resistance to increase sharply, causing motor overload (excessive current), increasing the maintenance frequency, and affecting the continuity of production. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a safety protection device for a toothed roller grading crusher, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety protection device for a toothed roller classifying crusher, comprising a toothed roller classifying crusher body, a feed hopper, and a side frame. The feed hopper is fixedly connected to the top of the toothed roller classifying crusher body, and one side of the side frame is fixedly connected to the toothed roller classifying crusher body. A guide frame and a support frame are fixedly connected inside the side frame, and the support frame is located at the bottom of the guide frame. A monitoring component is provided on the support frame. The monitoring component includes a mounting frame, a laser emitter, a laser receiver, and an insert plate. The laser emitter and laser receiver are respectively fixedly installed on both sides inside the mounting frame. One side of the insert plate is fixedly connected to the mounting frame, and the other side of the insert plate extends into the interior of the support frame. An alarm is fixedly installed on the front side of the side frame.

[0007] Furthermore, the insert plate is provided with locking bolts, and the insert plate is fixed to the support frame by the locking bolts.

[0008] It can be seen that the above technical solution facilitates the disassembly and maintenance of the laser transmitter and laser receiver.

[0009] Furthermore, both the laser emitter and the laser receiver are provided with protective sleeves on their outer sides, and the opposite sides of the two protective sleeves are fixedly connected to the mounting bracket.

[0010] As can be seen, the above technical solution facilitates the protection of the laser emitter and laser receiver to prevent the raw materials from directly contacting the laser emitter and laser receiver.

[0011] Furthermore, the side frame is internally equipped with a feeding assembly, which includes a stepper motor, a lead screw, two sliders, two fixed frames, a limit rod, a storage frame, a self-locking motor, and two rotating shafts.

[0012] Furthermore, the stepper motor is fixedly mounted on the top of the side frame, and the output shaft end of the stepper motor is fixedly connected to the lead screw. The top and bottom ends of the lead screw are movably connected to the side frame through bearings, and the lead screw is threadedly connected to one of the sliders. The opposing sides of the two sliders are fixedly connected to the fixed frame.

[0013] It can be seen that the above technical solution is designed to facilitate the vertical movement of the storage frame.

[0014] Furthermore, the top and bottom ends of the limiting rod are fixedly connected to the side frame, and the other slider is movably sleeved on the limiting rod.

[0015] As can be seen, in the above technical solution, another slider and a limiting rod work together to restrict the rotation of the storage frame.

[0016] Furthermore, the two opposing ends of the two rotating shafts are fixedly connected to the storage frame, and the opposite ends of the two rotating shafts are movably connected to the two fixed frames through bearings. The self-locking motor is fixedly installed inside one side of one of the fixed frames, and the output shaft end of the self-locking motor is fixedly connected to one of the rotating shafts.

[0017] It can be seen that the above technical solution is designed to facilitate the rotation of the storage frame.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. This utility model emits a laser beam through a laser emitter and receives the laser beam through a laser receiver. When the laser receiver does not receive the beam within three seconds, it indicates that the feed hopper is blocked by raw materials. At this time, the alarm will sound to remind the staff to stop adding raw materials, turn the locking bolt away from the support frame, and disassemble and repair the laser emitter and laser receiver. The operation is simple and convenient for monitoring the amount of raw materials.

[0020] 2. This utility model uses a stepper motor to drive a lead screw to rotate. The lead screw can drive two sliders, two fixed frames, and a storage frame to move upward, so that the storage frame moves to the top of the guide frame. Then, the self-locking motor is started, which drives two rotating shafts to rotate, thereby driving the storage frame to rotate, so that the raw material in the storage frame moves into the guide frame. The structure is simple and convenient for adding raw materials. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Refer to the instruction manual appendix Figure 1-5 This embodiment of a safety protection device for a toothed roller classifying crusher includes a toothed roller classifying crusher body 1, a feed hopper 2, and a side frame 3. The feed hopper 2 is fixedly connected to the top of the toothed roller classifying crusher body 1, and one side of the side frame 3 is fixedly connected to the toothed roller classifying crusher body 1. A guide frame 4 and a support frame 8 are fixedly connected inside the side frame 3, and the support frame 8 is located at the bottom of the guide frame 4. A monitoring component 5 is provided on the support frame 8. The monitoring component 5 includes a mounting frame 501, a laser emitter 502, a laser receiver 503, and an insert plate 504. The laser emitter 502 and the laser receiver 503 are respectively fixedly installed on both sides inside the mounting frame 501. One side of the insert plate 504 is fixedly connected to the mounting frame 501, and the other side of the insert plate 504 extends into the interior of the support frame 8. An alarm 7 is fixedly installed on the front side of the side frame 3.

[0030] Furthermore, the insert plate 504 is provided with locking bolts 505, and the insert plate 504 is fixed to the support frame 8 by locking bolts 505. The outer sides of the laser emitter 502 and the laser receiver 503 are both provided with protective sleeves 506, and the opposite sides of the two protective sleeves 506 are fixedly connected to the mounting frame 501.

[0031] Furthermore, the side frame 3 is internally equipped with a feeding assembly 6, which includes a stepper motor 601, a lead screw 602, two sliders 603, two fixed frames 604, a limiting rod 605, a storage frame 606, a self-locking motor 607, and two rotating shafts 608. The stepper motor 601 is fixedly mounted on the top of the side frame 3, and the output shaft end of the stepper motor 601 is fixedly connected to the lead screw 602. The top and bottom ends of the lead screw 602 are movably connected to the side frame 3 through bearings, and the lead screw 602 is threadedly connected to one of the sliders 603. The opposing sides of the sliders 603 are fixedly connected to the fixed frame 604. The top and bottom ends of the limiting rod 605 are fixedly connected to the side frame 3. The other slider 603 is movably sleeved on the limiting rod 605. The opposing ends of the two rotating shafts 608 are fixedly connected to the storage frame 606, and the opposing ends of the two rotating shafts 608 are movably connected to the two fixed frames 604 through bearings. The self-locking motor 607 is fixedly installed inside one side of one of the fixed frames 604, and the output shaft end of the self-locking motor 607 is fixedly connected to one of the rotating shafts 608.

[0032] The process involves adding raw materials into the storage frame 606, starting the stepper motor 601, which drives the lead screw 602 to rotate. Since one slider 603 is threadedly connected to the lead screw 602, and the other slider 603 and the limiting rod 605 cooperate to restrict the rotation of the storage frame 606, the lead screw 602 can drive the two sliders 603, the two fixed frames 604, and the storage frame 606 to move upwards, causing the storage frame 606 to move to the top of the guide frame 4. Then, the self-locking motor 607 is started, which drives the two rotating shafts 608 to rotate, thereby driving the storage frame 606 to rotate, so that the raw materials in the storage frame 606 move into the guide frame 4. The structure is simple and convenient for adding raw materials.

[0033] The usage method of this embodiment is as follows:

[0034] During use, the raw materials are guided by the guide frame 4 and enter the interior of the toothed roller grading crusher body 1 through the feed hopper 2. The laser emitter 502 is activated and emits a beam of light, which is received by the laser receiver 503. If the laser receiver 503 does not receive the beam of light within three seconds, it means that the feed hopper 2 is blocked by raw materials. At this time, the alarm 7 will sound an alarm to remind the staff to stop adding raw materials. The operation is simple and convenient for monitoring the amount of raw materials. At the same time, the locking bolt 505 is turned and moved away from the support frame 8, thereby releasing the fixation between the insert plate 504 and the support frame 8, and the laser emitter 502 and laser receiver 503 can be disassembled and inspected. The laser emitter 502 and laser receiver 503 can be protected by two protective sleeves 506, which can intercept most of the dust falling from above or around, reducing the probability of dust falling directly on the laser emitter 502 and laser receiver 503.
