there is a need in the art for a new solution to this problem.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model provides a maintainable ventilation unit which is used for solving the problems of labor waste and time waste and high maintenance cost of the ventilation unit during maintenance.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a maintainable ventilation unit comprises a cab middle top plate, a fan bottom plate, a fan shield and a fan; one end of a top plate in the cab is fixed through a first hinge, and a first four-corner lock is arranged at the other end of the top plate in the cab; the fan bottom plate and the fan shield enclose a box structure, one end of the fan bottom plate is fixed through a second hinge, and a second four-corner lock is arranged at the other end of the fan bottom plate; the fan is fixed on the top surface of the fan bottom plate, and the fan is arranged in the box body formed by the fan bottom plate and the fan shield in a surrounding mode.
The roof in the cab is provided with a first vent.
The fan bottom plate is provided with a second ventilation hole.
Through the design scheme, the utility model has the following beneficial effects:
1. one end of a top plate in the cab is connected by a hinge, and the other end of the top plate is locked by a four-corner lock, so that when maintenance is needed, the four-corner lock is only needed to be opened, and labor and time are saved;
2. the ventilation unit fan is arranged on the bottom plate, the bottom plate is of a turnover structure, one end of the bottom plate is connected through a hinge, and the other end of the bottom plate is locked through a four-corner lock, so that when maintenance is needed, only the four-corner lock is needed to be opened, and labor and time are saved; the maintenance cost is reduced.

Detailed Description
The following describes the embodiments of the present utility model in detail with reference to the drawings
It should be noted that the terms "front and rear," up and down, left and right, "and the like are merely simplified terms for intuitively describing the positional relationship based on the drawings, and are not limited to the technical solution.
In order to more clearly illustrate the present utility model, the present utility model will be further described with reference to preferred embodiments. Those skilled in the art will appreciate that. The following detailed description is illustrative rather than limiting, and the user may make various changes to the following parameters without departing from the inventive mechanism and scope set forth in the claims. Well-known methods and procedures have not been described in detail so as not to obscure the present utility model.
The method is shown in the accompanying drawings from 1 to 5: a maintainable ventilation unit comprises a cab middle top plate 1, a fan bottom plate 2, a fan shield 3 and a fan 4; one end of the roof 1 in the cab is fixed through a first hinge 11, and a first four-corner lock 12 is arranged at the other end of the roof 1 in the cab; the fan bottom plate 2 and the fan shield 3 enclose a box structure, one end of the fan bottom plate 2 is fixed through a second hinge 21, and a second four-corner lock 22 is arranged at the other end of the fan bottom plate 2; the fan 4 is fixed on the top surface of the fan bottom plate 2, and the fan 4 is arranged in the box body formed by enclosing the fan bottom plate 2 and the fan shield 3.
The roof panel 1 in the cab is provided with a first vent hole 13.
The fan bottom plate 2 is provided with a second ventilation hole 23.
In the concrete implementation, one end of the top plate 1 in the cab is connected by adopting a hinge, the other end is locked by using a four-corner lock, when maintenance is needed, the four-corner lock is only needed to be opened, the fan 4 of the ventilation unit is arranged on the fan bottom plate 2, the fan bottom plate 2 is of a turnover structure, one end is connected by adopting the hinge, the other end is locked by using the four-corner lock, when maintenance is needed, the four-corner lock is only needed to be opened, and after maintenance is finished, the fan bottom plate 2 and the top plate 1 in the cab can be arranged by only needing single operation due to the positioning function of the hinge, so that labor and time are saved; the maintenance cost is reduced.
