[0002] The ventilation grid is an important component of the heat dissipation of the bulldozer, and different ventilation grids need to be designed according to the actual working environment under different working conditions of different working environments due to the relatively complex and harsh working environment of the bulldozer. When the bulldozer works in the forestry environment, it will be affected by branches and leaves. The current structure of the ventilation grid of the bulldozer is a grid type with an opening upward. The ventilation grid of this structure cannot prevent the entry of branches and leaves when the bulldozer is working on the forest road, thereby causing damage to the fan and the radiator and causing the engine to be high temperature, which affects the normal work of the whole machine.

[0019] The application will be further described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative changes belong to the protection scope of the application.

[0020] As Figures 1-6As shown, the technical scheme adopted in the present application is: a forestry type air permeable grille for a bulldozer, comprising a front housing 1 and a grille 2 arranged at an air outlet of the front housing 1, wherein the grille 2 comprises at least a first air outlet area and a second air outlet area, the air permeable openings of the first air outlet area are arranged obliquely downward, the air permeable openings of the second air outlet area are arranged obliquely upward, and the first air outlet area is located above the second air outlet area.

[0021] In the present application, the grille 2 is divided into the first air outlet area with the air permeable openings arranged obliquely downward and the second air outlet area with the air permeable openings arranged obliquely upward, the first air outlet area can prevent fallen leaves and branches from entering the front housing 1 through the air permeable openings, the air permeable openings of the second air outlet area are arranged obliquely upward to avoid the air outlet from directly blowing to the ground to cause dust raising, which not only has the function and effect of reducing dust raising of the existing grille 2, but also can be effectively applied to forestry work to prevent leaves and branches from entering the front housing 1 and prevent damage to the radiator or fan.

[0022] In one embodiment, as shown in Figure 1 The grille 2 comprises a frame 21 and a plurality of leaf plates 22, the frame 21 is arranged around the plurality of leaf plates 22 to form the air permeable openings between adjacent two leaf plates 22, the leaf plates 22 in the first air outlet area are arranged obliquely downward, and the leaf plates 22 in the second air outlet area are arranged obliquely upward. The area of the first air outlet area and the area of the second air outlet area can be adjusted according to actual conditions, and the larger the area of the second air outlet area is, the lighter the dust raising phenomenon is, and the falling probability of leaves and branches increases. More specifically, the grille 2 is in a rectangular shape, comprising four frames 21 and a plurality of leaf plates 22, the plurality of leaf plates 22 are arranged transversely, and the four frames 21 are arranged around the plurality of leaf plates 22 to form the grille 2.

[0023] As another embodiment, as shown in Figures 2-4 In order to facilitate adjustment of the area of the first air outlet area and the area of the second air outlet area, the grille 2 comprises at least two grille modules 24, each grille module 24 comprises the frame 21 and the plurality of leaf plates 22, the frame 21 is arranged around the plurality of leaf plates 22 to form the grille module 24, the leaf plates 22 in the grille module 24 in the first air outlet area are arranged obliquely downward, and the leaf plates 22 in the grille module 24 in the second air outlet area are arranged obliquely upward. The size of each grille module 24 can be the same or different, as shown in Figures 2-4As shown, each lattice module 24 has four frames 21, and the four frames 21 enclose the plurality of lamellas 22 to form a lattice module 24. Two or more lattice modules 24 are combined to form the whole lattice 2. One or more lattice modules 24 with the lamellas 22 inclined downward form the first air outlet area, and one or more lattice modules 24 with the lamellas 22 inclined upward form the second air outlet area. In this way, the number of lattice modules 24 can be set according to actual needs, and the area ratio of the first air outlet area and the second air outlet area can be adjusted.

[0024] In one embodiment, as shown in Figure 5 and 6 In order to further avoid fallen leaves or branches entering the inside of the front cover 1 from the second air outlet area with the opening upward, the distance between the lamellas 22 of the second air outlet area and the outside of the frame 21 is less than the distance between the lamellas 22 of the first air outlet area and the outside of the frame 21. That is, the lamellas 22 of the second air outlet area are more recessed into the air outlet of the front cover 1 than the lamellas 22 of the first air outlet area, further reducing the probability of fallen leaves or branches entering the inside of the front cover 1.

[0025] In another embodiment, as shown in Figures 1-5 In order to strengthen the strength of the lattice 2, the lattice 2 further comprises a support frame 23, which is vertically arranged between the plurality of lamellas 22 and is located between the frames 21.

[0026] In one embodiment, as shown in Figure 1 In order to facilitate the installation of the lattice 2, one side of the lattice 2 is provided with a hinge hole 25, and the front cover 1 is provided with a hinge seat 11. A pin shaft passes through the hinge hole 25 and the hinge seat 11 to hinge the lattice 2 to the air outlet of the front cover 1. The other side of the lattice 2 is fixedly connected to the air outlet of the front cover 1 by bolts. In this way, in the case of poor working conditions, i.e. in the case of many fallen leaves and branches, the lattice 2 can be closed to prevent debris from entering the front cover 1. In the case of good working conditions, i.e. in the case of no fallen leaves and branches, the side of the lattice 2 can be unbolted, and the lattice 2 can be hinged to the front cover 1. The lattice 2 can be completely opened by the hinge structure, the air outlet is completely exposed, and the heat dissipation effect is improved.

[0027] In one embodiment, as shown in Figure 1 In order to further improve the protection effect, a protective net 3 is further included. The protective net 3 is fixedly installed on the inner side of the lattice 2, and the hole size of the protective net 3 is smaller than the size of the air-permeable opening. Even if fallen leaves or branches fall vertically into the lattice 2, the protective net 3 can further block them to prevent affecting the fan, radiator and other components.

[0028] Although the present disclosure discloses as above, the protection scope of the present disclosure is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
