[0031] The following describes the detailed embodiment of the present application with reference to the accompanying drawings. It should be understood that the detailed embodiment described herein is only for explaining and illustrating the present application, and is not used to limit the present application.

[0032] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0033] As Figures 1 to 3 shown, the first exemplary embodiment of the present application provides an engine shroud, which can be integrally disposed on the body of an agricultural machine and cover the engine located on the body. Specifically, the engine shroud of this exemplary embodiment includes a circumferential shroud and a top shroud 1. Among them, the circumferential shroud is formed by enclosing the grain bin wall 2, the radiator wall 3 and the partition board 4 in a circumferential direction, and encloses an engine cavity 5 for accommodating the engine. The top shroud 1 is movably disposed on the top of the circumferential shroud to open and close the top opening 6 located at the top of the engine cavity 5.

[0034] In this embodiment, the grain box and the radiator are both arranged adjacent to the engine. The grain box wall 2 is a part of the grain box housing, and the radiator wall 3 is a part of the radiator housing. It can be seen that the engine hood of this exemplary embodiment can simultaneously use the grain box wall 2 and the radiator wall 3 to enclose the engine, simplifying the design of the engine hood. Based on the grain box wall 2 and the radiator wall 3, only an additional partition 4 and a top cover 1 need to be provided to effectively protect the engine, while reducing the production cost of the engine hood. In addition, the top cover 1 is movably arranged on the top of the circumferential cover, so as to facilitate controlling the opening and closing of the engine cavity 5 and convenient for maintenance personnel to perform maintenance on the engine from the top opening 6. At the same time, using a lightweight top cover 1 can make it more labor-saving to open the top cover 1.

[0035] In an alternative or preferred embodiment, as Figure 1 shown, the circumferential cover further forms a side opening 7. The grain box wall 2, the radiator wall 3 and the partition 4 are connected in sequence along the circumference, and the side opening 7 is formed between the grain box wall 2 and the partition 4. Thus, when the top cover 1 is in the closed state, the engine hood of this embodiment can form a one-sided open air duct. The cooling air is sucked from one side of the radiator wall 3 into the engine cavity 5, and after cooling the engine, the cooling air flows out from the side opening 7, thereby improving the air fluidity and the heat dissipation effect of the radiator.

[0036] In an alternative or preferred embodiment, as Figure 1 and Figure 3 shown, the engine hood includes a pivot connection member 8 arranged at the top of the grain box wall 2. One end of the top cover 1 is movably connected to the pivot connection member 8, and the other end is detachably connected to the top of the partition 4. Connecting the top cover 1 and the grain box wall 2 through the pivot connection member 8 enables the top cover 1 to achieve flipping adjustment, that is, the top cover 1 can be opened or closed in a flipping manner, and at the same time, the distance between the top cover 1 and the grain box wall 2 can be adjusted, that is, the flipping radius of the top cover 1 can be adjusted. Thus, when there is welding deformation in the grain box wall 2 or the partition 4 resulting in the other end of the top cover 1 being unable to be effectively connected to the top of the partition 4, by adjusting the distance between the top cover 1 and the grain box wall 2, that is, adjusting the flipping radius of the top cover 1 itself, the problem that the top cover 1 cannot be connected to the partition 4 can be effectively solved.

[0037] The specific form of the pivotal connection formed by the top cover 1 and the grain box wall 2 can refer to Figure 3, the pivot connecting member 8 includes a fixed seat weldment, a pin shaft, and a hinge weldment. Among them, the fixed seat weldment is installed on the top of the grain bin wall 2 through bolts. The hinge weldment is connected to the fixed seat weldment through the pin shaft. The hinge weldment is provided with an oblong hole. One end of the top cover 1 is provided with a positioning hole aligned with the oblong hole. By passing bolts through the oblong hole and the positioning hole, the top cover 1 can be connected to the hinge weldment, realizing the flipping adjustment of the top cover 1. At the same time, by adjusting the relative position of the bolt and the oblong hole, the relative position between the top cover 1 and the grain bin wall 2 can be adjusted along the axis direction of the oblong hole, that is, the distance between the top cover 1 and the grain bin wall 2 can be adjusted. In some other embodiments, a sliding fit or the like can also be formed between the top cover 1 and the grain bin wall 2 to achieve distance adjustment, and the present application does not limit this.

[0038] Further, as Figure 1 shown, the engine hood includes a gas spring 9 whose two ends are respectively hinged to the top cover 1 and the grain bin wall 2. Specifically, a first hinge seat is provided on the bottom wall of the top cover 1, and a second hinge seat is provided on the outer side wall of the grain bin wall 2. The two ends of the gas spring 9 are respectively hinged to the first hinge seat and the second hinge seat. When the top cover 1 is in the closed state, the gas spring 9 is in a compressed state. When the top cover 1 is opened, that is, when the top cover 1 is flipped upward, the gas spring 9 changes from the compressed state to the extended state, thereby driving the top cover 1 to flip upward until the gas spring 9 extends to the maximum elongation or extends to a preset length. At this time, the top cover 1 is flipped up to the pre-opened angle, and the gas spring 9 supports the top cover 1. Generally speaking, by using the gas spring 9 to assist in opening and closing the top cover 1, the opening and closing force of the top cover 1 can be effectively saved, and the convenience of opening and closing the top cover can be improved.

[0039] In an alternative or preferred embodiment, the top cover 1 includes a first cover 101 and a second cover 102. Among them, the first cover 101 is fixedly connected to the grain bin wall 2, and the second cover 102 is movably connected to the first cover 101. For example, the second cover 102 forms a sliding connection with the first cover 101. By moving the second cover 102, the distance between the second cover 102 and the grain bin wall 2 can be adjusted, thereby also solving the problem that the top cover 1 cannot be effectively connected to the partition 4 due to welding deformation of the box wall 2 or the partition 4.

[0040] Specifically, as Figure 4As shown, the first housing 101 is fixedly connected to the grain bin housing wall 2. The second housing 102 includes a frame structure 1021 and a cover plate 1022. Among them, the frame structure 1021 is lapped on the first housing 101 and can move relative to the first housing 101. For example, long oblong holes are provided on the first housing 101 or the frame structure 1021 and bolts are passed through these long oblong holes, or a slide rail is provided on one of the first housing 101 and the frame structure 1021, and a slider that forms a sliding fit with this slide rail is provided on the other. This application does not make a limitation on this, as long as the movable connection between the frame structure 1021 and the first housing 101 can be achieved. Thus, by adjusting the relative position between the frame structure 1021 and the first housing 101, the length of the entire top housing 1 can be changed, so that the top housing 1 can adapt to the dimensional deviation between the grain bin housing wall 2 and the partition plate 4 to fully cover the top opening 6. At the same time, the frame structure 1021 forms a frame opening that communicates with the top opening 6 in alignment, thereby reserving an engine maintenance space, enabling maintenance personnel to perform maintenance on the engine through the frame opening. The cover plate 1022 is movably arranged on the frame structure 1021 to open and close the frame opening. In Figure 4 In the illustrated embodiment, an opening-and-closing type cover plate is used as the cover plate 1022, that is, two cover plates 1022 are provided. The two cover plates 1022 are respectively installed on both sides of the frame structure 1021 through hinges. By flipping the two cover plates 1022 or one of the cover plates 1022, the frame opening can be opened and closed. The cover plate 1022 can be made of aluminum alloy or plastic material to reduce the weight, so that maintenance personnel can easily open and close the cover plate 1022.

[0041] In the above embodiment, considering the gap between the first housing 101 and the second housing 102, referring to Figure 4 , the top housing 1 further includes a rubber covering member provided between the first housing 101 and the second housing 102. This rubber covering member is installed at the outer end of the first housing 101 or at the inner end of the second housing 102, and can cover the gap between the first housing 101 and the second housing 102 to prevent rainwater from flowing into the engine cavity through the gap.

[0042] In an alternative or preferred embodiment, as Figure 1 shown, the top housing 1 is provided with a housing opening 103 for the air-conditioning pipeline to pass through, thereby reducing the difficulty of pipeline layout. Further, in order to prevent rainwater or sundries from falling into the engine cavity, the top housing 1 is further provided with a housing cover for covering the housing opening 103. In actual application, a flexible rubber sheet can be used as the housing cover for covering the housing opening 103, so as to facilitate opening the housing opening 103.

[0043] In an alternative or preferred embodiment, as Figures 1 to 3As shown, an auxiliary ladder installation position 401 for installing the auxiliary ladder 10 is provided on the outer side wall of the partition plate 4. By installing the auxiliary ladder 10 on the auxiliary ladder installation position 401, maintenance personnel can climb to the top surface of the top cover 1 through the auxiliary ladder 10, and then perform maintenance operations on components such as the engine and the grain tank. Correspondingly, the top surface of the top cover 1 can be anti-slip treated, such as laying a rubber mat. Further, the top cover 1 is provided with a cover overlapping portion 104 for overlapping with the top of the auxiliary ladder 10. Thus, when the auxiliary ladder 10 is installed on the partition plate 4, when the top cover 1 is closed on the top of the circumferential cover, one end of the top cover 1 is connected to the partition plate 4, and the top cover 1 overlaps on the top of the auxiliary ladder 10 through the cover overlapping portion 104, thereby avoiding interference of the auxiliary ladder 10 with the closing of the top cover 1.

[0044] In an alternative or preferred embodiment, as Figure 2 shown, the engine shroud further includes a buckle seat provided at the end of the top cover 1 and a box buckle provided at the top of the partition plate 4. The buckle seat can be detachably buckled to the box buckle, so that the top cover 1 can form a detachable connection with the partition plate 4. Especially when the top cover 1 is in a closed state, it is convenient to lock the top cover 1 to prevent the top cover 1 from opening the top opening 6 due to vibration or other reasons.
