[0002] A double-roll crusher usually has two pairs of rollers that rotate relative to each other to achieve the crushing and tearing of the crushed materials. In order to improve the efficiency of grabbing objects, corresponding tooth structures are usually set on the crushing rollers to press down on objects to prevent them from escaping from the feed port. When manually delivering objects, under the influence of some force majeure factors, workers' clothes and other items are easily brought into the feed port of the crusher, thereby involving human limbs in the crusher. In recent years, there have been many accidents involving crushers injuring people. When a person is involved in the crusher, due to the limited movement of the local limbs, even if an emergency stop button is installed around the equipment, it cannot be guaranteed that the person can press the emergency stop button when an accident occurs.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] Example:

[0026] The utility model provides a double-roll crusher, which collects sound through a microphone and distinguishes the sound through an analyzer. After identifying the human voice, the equipment can be stopped urgently and the two crushing rollers can be moved away from each other, which is conducive to timely preventing accidents and improving the operational safety of the equipment. To realize the structural function of the equipment, the equipment includes a first mounting bracket 1, a second mounting bracket 2, a second driving device 17, a controller and a sound analyzer. For details, refer to Figure 1-Figure 4 As shown, a first crushing roller 6 is rotatably mounted on the first mounting bracket 1, and a second crushing roller 7 is rotatably mounted on the second mounting bracket 2. The first mounting bracket 1 is arranged to be slidably mounted relative to the second mounting bracket 2, so that the first crushing roller 6 can be close to or away from the second crushing roller 7, so that when an accident occurs, the two crushing rollers can be automatically separated to leave a safe space for operators to escape. The first mounting bracket 1 and the second mounting bracket 2 are respectively equipped with a first driving device 8 for driving the corresponding first crushing roller 6 and second crushing roller 7 to rotate, so that the equipment can work normally, and the second driving device 17 is used to drive the first mounting bracket 1 to slide relative to the second mounting bracket 2; in order to prevent workers from being unable to move when being involved The emergency stop button cannot be touched. A microphone 9 is installed on the first mounting bracket 1 and / or the second mounting bracket 2 for converting the obtained sound signal into an electrical signal and collecting the amplitude and waveform of the sound. The microphone 9 is electrically connected to a sound analyzer. The sound analyzer is used to analyze the waveform, amplitude and duration of the obtained electrical signal and determine whether the currently emitted sound is a human voice. If a human voice or a human voice with fixed characteristics is detected, it is necessary to stop the operation of the equipment in time to avoid accidents. For this purpose, the analyzer, the first drive device 8 and the second drive device 17 are all electrically connected to the controller so that the controller can send relevant control signals to realize the regulation of the equipment. The system connection diagram can refer to Figure 5 shown.

[0027] The utility model provides a double-roll crusher. When the crusher is working, it is easy to generate large noise at the crushing position. For this reason, the microphone 9 can be designed as a gun-type microphone, wherein the sound receiving source of the gun-type microphone points to the position above the first crushing roller 6 and the second crushing roller 7, so as to reduce the interference of the sound emitted by the two crushing rollers on the sound source position and affect the normal analysis. Since the gun-type microphone obtains less noise at the non-pointing position, and the workers may be at different positions around the equipment, the number of gun-type microphones can be set to be multiple, each pointing to the position where the workers are most likely to be.

[0028] A double-roll crusher provided by an embodiment of the utility model can be supplemented with an emergency stop switch 10 on the first mounting bracket 1 and / or the second mounting bracket 2 in order to further improve the safety performance of the equipment. The emergency stop switch 10 can be electrically connected to the controller, which is conducive to workers adopting different response measures to further reduce the occurrence of accidents.

[0029] The utility model provides a double-roll crusher. In order to prevent workers from repeatedly accidentally touching the emergency stop switch 10, which causes the equipment to fail to work normally and effectively, a semi-open protective cover 11 is provided on the emergency stop switch 10. The semi-open protective cover 11 is rotatably arranged above the first mounting bracket 1 or the second mounting bracket 2. The opening position of the semi-open protective cover 11 is used to expose a part of the emergency stop switch 10. The emergency stop switch 10 can be protected from accidental touching while being pressed to realize emergency stop without the need for workers to open the cover.

[0030] The utility model provides a double-roll crusher. Considering that the two crushing rollers of the crusher need to be able to withstand a large pressure, in order to ensure that the corresponding drive can drive the two crushing rollers to move closer or farther from each other while supporting the pressure of the two crushing rollers, a connecting plate 3 can be relatively fixedly installed on the second mounting bracket 2, and a plurality of first guide rails 4 are installed on the connecting plate 3. The first mounting bracket 1 is slidably installed on the first guide rail 4 through the first slider 5, and the second drive device 17 is set as a hydraulic push rod. The output end of the hydraulic push rod is connected to the first mounting bracket 1, and the second drive device 17 is prevented from collapsing by the hydraulic force. In order to further reduce the pressure on the hydraulic push rod 17, specifically, refer to Figure 1 As shown, it also includes a connecting rod 16. Specifically, a connecting block 12 is installed on the first mounting bracket 1, a vertically arranged second guide rail 13 is installed on the second mounting bracket 2, a second slider 14 is slidably installed on the second guide rail 13, a rotating seat 15 is provided on the connecting block 12 and the second slider 14, and both ends of the connecting rod 16 rotate on the two rotating seats 15 respectively. The output end of the hydraulic push rod is used to control the second slider 14 to slide back and forth in the sliding direction provided by the second guide rail 13, so that the second slider 14 can drive the connecting rod 16 to push the connecting block 12 and the first mounting bracket 1. By controlling the angle between the connecting rod 16 and the horizontal plane to be always less than 45° during the action process, if F1 represents the push and pull force of the hydraulic push rod, and F2 represents the lateral force on the connecting block 12, then:

[0031] F2 = F1COTα;

[0032] Where α is the angle between the connecting rod 16 and the horizontal plane. α When it is less than 45 degrees, F2 will be greater than F1, which means that the force amplification effect of the hydraulic push rod 17 is achieved. Conversely, the force requirement of the hydraulic push rod 17 is reduced, which is beneficial to improving the reliability of the equipment.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
