[0002] As an important earthwork construction machine, the continuous optimization of the performance and structure of loaders is an important direction for the development of the industry. Traditional loaders are usually large in size, complex in structure, and high in maintenance cost, making it difficult to be applied to narrow or complex working environments. Therefore, for different working environments, it is necessary to develop new mini four-wheel drive loaders to meet the market demand for miniaturization;

[0003] During the R & D process of our company, basically the driving equipment is set inside the frame. For example, in this equipment, the diesel engine is set inside the frame, and then the diesel engine is protected by a protective hood, and a seat is set on the protective hood, thus effectively reducing the body size of the loader; and other components inside the frame will be preferentially located in the protective hood for protection according to requirements; however, due to the protection of the diesel engine by the hood, it is necessary to make adaptive improvements to the hood and make it convenient to open and maintain the equipment inside the hood; therefore, in view of the above problems, there is an urgent need for a seat hood that can adapt to the shape of the diesel engine.

[0027] Embodiment 1:

[0028] Please refer to Figure 1 - Figure 3 , the protective hood of the loader of the present utility model includes a hood body 3 installed on the frame 1 and covering the diesel engine 2. The hood body 3 is movably installed on the frame 1 through a connecting component 9, and the hood body 3 is installed on the frame 1 through a locking mechanism 7;

[0029] A seat 5 is provided on the top of the hood body 3;

[0030] A fuel filling hole 31 corresponding to the fuel tank cap of the diesel engine 2 is provided on the top of the hood body 3; a mounting hole 32 for the exhaust pipe of the diesel engine 2 to extend out is opened on the side surface of the hood body 3 corresponding to the side surface of the diesel engine 2, and the bottom of the mounting hole 32 is open to facilitate the exhaust pipe to enter the mounting hole 32.

[0031] A tail plate 6 is provided at the tail of the frame 1, and the hood body 3 is rotatably mounted on the tail plate 6 through a connecting member 9, and the connecting member 9 is a hinge, a rotating shaft or a hinge;

[0032] The baffle 4 is fixedly connected to the hood body 3, and can be synchronously carried to rotate by the rotation of the hood body 3.

[0033] The locking mechanism 7 includes latches 71 installed on both sides of the frame 1 and hooks 72 correspondingly installed on both sides of the hood body 3; the hood body 3 is locked by the latches 71 being latched on the hooks 72.

[0034] In this embodiment:

[0035] By setting the hood body 3 in an inverted U shape and opening mounting holes 32 in the hood body 3, it can effectively conform to the extension of the exhaust pipe of the diesel engine 2, thereby protecting the diesel engine 2. In this embodiment, by making the hood body 3 rotate backward through the connecting member 9, when the latch 71 of the locking mechanism 7 is not connected to the hook 72, the hood body 3 can directly carry components such as the seat 5 and rotate backward, so that while specifically protecting the diesel engine 2, it is also convenient to perform maintenance after removing the shroud of the diesel engine 2.

[0036] In this embodiment, right-angle limit plates 8 are provided on both sides of the frame 1 corresponding to the baffle 4 and on both sides of the hood body 3. The right-angle limit plates 8 can limit the front end of the hood body 3, thereby facilitating the locking of the locking mechanism 7.

[0037] Embodiment Two:

[0038] In the technology of Embodiment One, by rotating, the protection of the diesel engine 2 by the hood body 3 is released, so as to facilitate the maintenance of the diesel engine 2 inside the hood body (3). However, due to the working environment of this equipment, slag and stones are likely to remain at the connecting member 9 after loading. And due to the weight of the body, it is not easy to slowly lower the flipped hood body 3. When the flipping speed of the hood body 3 is too fast and the slag and stones are not cleared, the rotating shaft, hinge and other mechanisms of the connecting member 9 are likely to be damaged by impact;

[0039] Please refer to Figure 4 , as a variation of Embodiment One, the connecting member 9 includes a slide rail 91 installed on the frame 1, and a slide bar 92 is slidably connected inside the slide rail 91. The top of the slide bar 92 is detachably connected to the hood body 3 by bolts or screws.

[0040] A sliding block 10 is rotatably connected to the top of the baffle 4, and a sliding rail 11 for the sliding of the sliding block 10 is fixedly connected to the top inner wall of the hood body 3.

[0041] One side of the mounting hole 32 close to the baffle 4 is open;

[0042] On the side of the baffle plate 4 close to the mounting hole 32, a fitting plate 41 adapted to the mounting hole 32 is vertically provided, and the bottom of the fitting plate 41 is arc-shaped.

[0043] The locking mechanism 7 includes a locking screw 73 installed on the side of the slide rail 91, and a locking hole 74 adapted to the locking screw 73 is formed on the slide bar 92.

[0044] When using the present utility model:

[0045] By rotating the baffle plate 4, the fitting plate 41 can be driven to rotate synchronously, so that the front end of the air outlet pipe in the diesel engine 2 and the mounting hole 32 is unblocked. Then, the engine hood body 3 moves on the slide rail 91 through the slide bar 92, and the engine hood body 3 can be horizontally disengaged from covering the diesel engine 2. While having the characteristics of protecting the diesel engine 2, the engine hood body 3 can be conveniently opened by pushing, thus avoiding the problems existing when the engine hood body 3 is opened in the first embodiment.

[0046] The above is only the embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
