The existing mining machine cab is usually composed of a steel frame, and tempered glass and a cab door are installed in the hollow part of the frame. When glass is installed on the upper part of the cab, it is easy to cause the temperature in the cab to be too high due to sunlight or other heat radiation. However, the insulation material is directly fixed in the cab, which is not convenient to take out and replace when used for a long time, and ventilation cannot be opened. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a mining machine cab with a heat-insulating ceiling, which is convenient for removing the heat-insulating material and does not affect normal ventilation when the heat is not insulated.

It is characterized in that a top frame is provided on the upper part of the cab frame, a bracket is fixedly installed between the top frame and the cab frame, a heat-insulating winding layer assembly is installed on the inner upper side of the cab frame, the heat-insulating winding layer assembly comprises a double-track slide, a winding shaft is provided on the rear side of the double-track slide, a heat-insulating layer is wound on the outside of the winding shaft, a front end of the heat-insulating layer is fixedly installed on two sliders of the double-track slide, and a motor is provided on one side of the winding shaft.

[0006] Preferably, the output shaft of the motor is connected to one end of the winding shaft through a coupling, and the other end of the winding shaft is connected to a bearing of the cab frame.

[0007] Preferably, the motor and the double-track slide are both fixed to the cab frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. In the utility model, the arrangement of the double-track slide, the heat insulation layer, the winding shaft and the motor is conducive to opening or winding the heat insulation layer, facilitating the removal of the heat insulation material, and does not affect normal ventilation when heat insulation is not provided.

[0010] 2. In the utility model, the provision of the top frame and the bracket is helpful to reduce the situation where large stones on the upper part roll down to the front glass layer, thus protecting the cab frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, a mining machine cab with a heat-insulating ceiling comprises a cab frame 1, a front glass layer 2 is installed at the front hollow of the cab frame 1, an upper glass window 7 is installed at the upper hollow of the cab frame 1, the upper glass window 7 adopts a top-hung tempered glass window, a seat frame 3 is fixedly installed on the inner rear side of the cab frame 1, warehouse doors 4 are installed on the left and right sides of the cab frame 1, a top frame 5 is arranged on the upper part of the cab frame 1, the top frame 5 is arranged as an arc-shaped hollow steel frame with a high front and a low rear, a bracket 6 is fixedly installed between the top frame 5 and the cab frame 1, and a heat-insulating winding layer assembly 8 is installed on the inner upper side of the cab frame 1.

[0016] In this embodiment, combined with the Figure 2 As shown, the heat insulation winding layer assembly 8 includes a double-track slide 81, a winding shaft 83 is arranged at the rear side of the double-track slide 81, a heat insulation layer 82 is wound around the outside of the winding shaft 83, the front end of the heat insulation layer 82 is fixedly installed with two sliders of the double-track slide 81, a motor 84 is arranged at one side of the winding shaft 83, the motor 84 adopts a non-self-locking servo motor, the output shaft of the motor 84 is connected to one end of the winding shaft 83 by a coupling, the other end of the winding shaft 83 is connected to the bearing of the cab frame 1, and the motor 84 The double-track slide 81 is fixed to the cab frame 1, and the double-track slide 81 and the motor 84 are connected to an external power supply. When heat insulation is needed, the user makes the double-track slide 81 pull open the heat insulation layer 82, and the heat insulation layer 82 plays a role of reflective heat insulation. When heat insulation is not needed, the motor 84 drives the winding shaft 83 to rotate to wind up the heat insulation layer 82, and an external light source can be used through the upper glass window 7 or it can be opened for ventilation, and the heat insulation layer 82 can be easily accessed, so that the heat insulation layer 82 can be removed and replaced.
