Description

 Description Mobile crusher technology field.

 The present invention relates to a mobile crusher having a crushing function and capable of moving by itself. Background technology

 As shown in FIGS. 5 and 6, a conventional mobile crusher has an engine, a cooling device, electrical equipment, a hydraulic pump, a hydraulic operating valve, and a solenoid valve at the rear of a frame 41 having a traveling device 40. It is equipped with a power unit 42 equipped with the above. On the left side of the frame 41, a traveling platform 44 having a traveling lever 43 is provided, and a control unit 45 for traveling and working equipment is provided. As shown in FIG. 7, the crusher body 50 mounted at the center of the frame 41 is driven via a belt 52 by a drive motor 51 mounted in front of the frame 41. The belt 52 is covered with a belt cover 53.

A hopper frame 60 having a hopper 61 is mounted in front of the frame 41, and a plate feeder 62 is provided below the hopper 61. A magnetic separator 63 is hung below the hopper frame 60 as necessary. A belt conveyor 64 is suspended between the hopper frame 60 and the frame 41. Above the frame 41, a left working space 65 and a right working space 66 are provided on the left and right, so that the inside of the hopper 61 and the crusher body 50 can be monitored. The entire mobile crusher can be moved by the traveling device 40. During traveling, the operet moves by operating the traveling lever 43 and the control unit 45 in the traveling space 44. At the time of the crushing work, the operator operates the control section 45 to operate the work machines such as the plate feeder 62, the crusher body 50, and the belt conveyor 64 to perform the work. As shown in Fig. 7, the crushed material 70 0 Is sent to the crusher main body 50 by the plate feeder 62 to be crushed, and the crushed object 71 is sent to the front of the vehicle body by the belt conveyor 64 and discharged.

 However, such a configuration causes the following problems.

 (1) When moving a mobile crusher to a remote location, it must be mounted on a truck, etc., but in the case of a large crusher, it must be disassembled and transported. In this case, the belt cover 53 must be removed, the belt 52 must be removed, and then the crusher body 50 must be removed. Also, when assembling, the crusher body 50 must be installed on site, the belt 52 must be hung, the tension must be adjusted, and then the belt cover 53 must be installed. It takes a lot of time.

 (2) Since the control section 45 is located near the traveling space 44, abnormalities occur during monitoring of crushing work in the working space 65 or 66 (for example, clogging of the crushed objects 70, 71, foreign matter, etc.). If mixing occurs or the crusher body 50 is overloaded, etc.), the work cannot be stopped immediately or the crushing speed cannot be reduced.

 (3) When moving between the working spaces 65, 66 and the traveling space 44, there is a risk that the operator may come into contact with the traveling lever 43, so it is desirable that the operator can work without moving. I have. Disclosure of the invention

 SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and is easy to disassemble and assemble during transportation, can quickly operate a work machine when an abnormality occurs, and has good workability. The purpose is to provide a machine.

 The mobile crusher according to the present invention,

A mobile crusher that includes a power unit having an engine, a hydraulic pump and a hydraulic control valve, a frame having a traveling device, and a crusher body, and crushes and discharges crushed materials by a working machine such as the crusher body. At

A power unit and a control unit for controlling the traveling of the traveling device and the operation of the work equipment. A knit, a crusher unit having at least a crusher body, a hottub feeder unit for supplying the crushed object to the crusher body, a conveyor unit for discharging the crushed crushed object, a traveling device and a frame. It is characterized in that it is provided with a frame unit that can be detachably attached.

 In addition, the crusher unit may include a crusher main body and a crusher driving unit that drives the crusher main body, which are integrally formed. Further, the crusher nit may be provided with either a jaw crusher or an impact crusher serving as a crusher body so as to be exchangeable. Furthermore, the control unit may be provided with a traveling control unit for controlling the traveling device and a work implement control unit for controlling the work implement separately.

 With this configuration, the crusher has a unity configuration, which facilitates disassembly and assembly. In particular, when the crusher main body and the crusher drive unit are integrally configured, adjustment of the crusher drive unit is not required when the crusher unit is attached / detached, so that work can be performed easily and in a short time. Therefore, when transported by truck or the like to a remote location, good transportability and assemblability can be obtained. Furthermore, since crushers with different crushing characteristics can be used interchangeably, a single mobile crusher can meet multiple requirements. Furthermore, since the work equipment control is provided separately, it is possible to quickly operate the work equipment in the event of an abnormality while monitoring the crushing work.
