Description

Technical Field

[0001] The invention relates to the technical field of mobile crushers, in particular to a mobile crusher for mines. Background Art

[0002] In many industries such as metallurgy, construction, chemical industry, and materials, it is necessary to crush large pieces of materials into fine particles that meet production requirements. The process of reducing the particle size of the materials is called the crushing process. Generally, the crushing process is completed by mechanical equipment. The commonly used equipment is the cone crusher. The working gap is a key parameter of the cone crusher, which refers to the size of the crusher's discharge port. The working gap is related to the result of the crushing work. Therefore, the measurement and adjustment of the working gap of the cone crusher is very important. Its adjustment is relatively convenient and can be achieved manually or by the equipment itself; its measurement is also relatively convenient when the crusher stops working, but it is very difficult when the crusher continues to work. The measurement data is inaccurate and cannot be completed manually. Stopping the work for measurement affects production efficiency. Summary of the invention

DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-5 , the present invention provides a technical solution:

[0019] A mobile crusher for mining includes a vehicle body 1, and six legs 2 are arranged at the bottom of the vehicle body 1. Each leg 2 is provided with an independent telescopic system, so that it can be flexibly parked on a construction site that is not flat enough. The vehicle body 1 is provided with a level sensor 3, and the level sensor 3 is used to detect the balance state of the vehicle body 1 and make adjustments to ensure that the crusher operates on a stable platform. The bottom of the leg 2 is rotatably connected to a bottom plate 5, and the bottom plate 5 can rotate around the bottom of the leg 2 within a certain range, so as to reduce the tilting of the support point of the leg 2 due to the uneven ground, resulting in the unreliable support of the leg 2, and increase the contact effect between the bottom plate 5 and the ground. A pressure sensor is provided at the bottom of the bottom plate 5, and the pressure sensor is used to detect whether the contact between the bottom plate 5 and the ground is tight.

[0020] A cone crusher 4 is arranged on one side of the top of the vehicle body 1. The cone crusher 4 includes a frame body 401, a moving cone 402, an adjusting sleeve 403 and a fixed cone 404. An annular track 406 is fixedly connected to the outer wall of the adjusting sleeve 403. The annular track 406 is used to connect the distance detection sensor 6 when the adjusting sleeve 403 rotates. An annular dovetail groove 405 is provided on the bottom surface of the annular track 406. The distance detection sensor 6 is slidably connected with the annular dovetail groove 405. The annular dovetail groove 405 is used to drive the dovetail slide bar 601 to move up and down while not separating from the distance detection sensor 6 when the adjusting sleeve 403 rotates. Distance detection sensors 6 are evenly arranged between the gaps of the frame body 401 and the adjusting sleeve 403. The distance detection sensors 6 are used to detect the distance between the gaps of the frame body 401 and the adjusting sleeve 403, so as to calculate the gap distance between the moving cone 402 and the fixed cone 404. The bottom of the distance detection sensor 6 is fixedly connected to the frame body 401.

[0021] The distance detection sensor 6 includes an outer sleeve 607, the inner side of the outer sleeve 607 is slidably connected to the inner sleeve 603, the inner wall of the inner sleeve 603 is provided with a conductor sleeve 606, the top of the inner sleeve 603 is fixedly connected to a dovetail slide bar 601 slidably connected to the annular dovetail groove 405, a roller is provided at the connection between the dovetail slide bar 601 and the annular dovetail groove 405, and the outer wall of the roller is made of a rubber material with a certain elastic effect, which reduces the direct vibration of the distance detection sensor 6 and prolongs the service life. The inner bottom of the outer sleeve 607 is fixedly connected to a magnetic core 604 plug-connected to the conductor sleeve 606, the outer wall of the magnetic core 604 is wound with a coil 605, and the bottom of the outer sleeve 607 is provided with a connection seat 602 fixedly connected to the frame body 401.

[0022] A circuit board is arranged in the connection base 602, the output signal of the circuit board is 4-20mA, and the optional voltage range is 0-10V. One end of the lead wire of the coil 605 is connected to the circuit board, and the induced object is the conductor sleeve 606. The conductor sleeve 606 is inserted into the coil 605 to cause the conductor inductance to change, and then the insertion depth, that is, the displacement, is measured. The measurement method is to apply an excitation signal at both ends of the coil 605, take the feedback signal at the midpoint of the coil 605 to measure the displacement, and calculate the displacement through the measured amplitude and phase values.

[0023] When the gap distance between the moving cone 402 and the fixed cone 404 needs to be adjusted, the adjusting sleeve 403 is controlled to rotate. Since the adjusting sleeve 403 is connected to the frame body 401 through a thread, the adjusting sleeve 403 is moved up and down, and then the annular track 406 fixed on the outer wall of the adjusting sleeve 403 is driven to move, and the dovetail slide bar 601 is driven to move through the annular track 406, and the inner sleeve 603 is driven to move through the up and down movement of the dovetail slide bar 601, and the inner sleeve 603 drives the conductor sleeve 606, causing the conductor inductance coefficient to change, and then the insertion depth, that is, the displacement, is measured. The gap distance between the moving cone 402 and the fixed cone 404 is calculated according to the distance value between the gap between the frame body 401 and the adjusting sleeve 403.
