[0036] The following is a detailed description of the specific embodiments of the present application with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0037] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0038] First of all, it should be noted that the radiator is an engine heat exchange device that dissipates the excess heat generated during the engine's operation by exchanging heat with the outside air. The radiator grille is an outer shell or cover used to protect and cover the radiator, which plays a role in aesthetics and dust prevention. When it is necessary to clean and repair the radiator, the radiator grille generally needs to be opened or disassembled in advance, and it is necessary to ensure that there is no interference with other components on the vehicle (such as the overall machine cover) in a narrow space.

[0039] As Figures 1 to 4 shown, the first exemplary embodiment of the present application provides a radiator grille for being arranged on the air inlet side of the radiator. The radiator grille mainly includes a grille body 1 and an opening and closing cover body. Among them, the grille body 1 forms a grille cavity for accommodating the radiator and a grille opening communicating with the grille cavity, which is convenient for the operator to clean and repair the radiator located in the grille cavity through the grille opening. The opening and closing cover body is used to open and close the grille opening and includes a first cover body 2 and a second cover body 3. Among them, the top of the first cover body 2 is rotatably connected to the top of the grille body 1. For example, the rotational connection between the two can be realized through a hinge 9, so that the overall opening and closing cover body can open and close the grille opening by flipping around a horizontal axis. The second cover body 3 is movably connected to the first cover body 2, so that the flipping radius of the opening and closing cover body can be adjusted.

[0040] It can be seen that the opening and closing cover body in the radiator grille of this exemplary embodiment can be flipped and adjusted relative to the grille body 1, so as to control the opening and closing of the grille opening. And the opening and closing cover body is in a split design form, and the second cover body 3 can move relative to the first cover body 2, so that the flipping radius of the opening and closing cover body can be adjusted, so as to be able to adaptively reduce the flipping radius of the opening and closing cover body, effectively avoid interference between the opening and closing cover body and other adjacent components (such as the overall machine cover), and at the same time increase the opening amplitude of the opening and closing cover body, which is convenient for cleaning and repairing the radiator main body in the grille cavity and the inner peripheral wall of the grille body 1, etc., and further reduces the space required to flip the opening and closing cover body upward to open the grille body 1.

[0041] In one embodiment, referring to Figure 1 and Figure 2 shown, the top of the second cover body 3 is rotatably connected to the bottom of the first cover body 2. For example, the rotational connection between the two can be realized through a hinge assembly composed of a hinge plate 10, a hinge shaft 11 and a positioning pin 12, so that when the first cover body 2 is flipped upward to open the grille body 1, the longitudinal length of the opening and closing cover body can be reduced by flipping the second cover body 3 downward, so as to enable the opening and closing cover body to avoid other components.

[0042] During the process of the second cover body 3 flipping around the bottom of the first cover body 2, as Figure 1As shown, the second cover 3 is arranged to remain in a natural hanging state during the flipping process of the first cover 2 without interfering with the adjacent outer cover of the whole machine.

[0043] In one embodiment, as Figure 1 shown, the first cover 2 includes a first frame 201 and a first corrugated mesh panel 202 disposed in the first frame 201. The second cover 3 includes a second frame 301 and a second corrugated mesh panel 302 disposed in the second frame 301. Among them, the first cover 2 and the second cover 3 can be meshed with each other through the first corrugated mesh panel 202 and the second corrugated mesh panel 302 to form a sliding connection, that is, the protruding portions of the first corrugated mesh panel 202 are engaged with the groove portions of the second corrugated mesh panel 302, and the groove portions of the first corrugated mesh panel 202 are engaged with the protruding portions of the second corrugated mesh panel 302. The second cover 3 can slide relative to the first cover 2 along the extending direction of the corrugations, so as to reduce the overall flipping radius of opening and closing the cover during the flipping process of the first cover 2.

[0044] Specifically, as Figure 3 shown, both the first corrugated mesh panel 202 and the second corrugated mesh panel 302 can be bent mesh panels, and their bent cross-sections are continuous trapezoids, so as to increase the air intake area of the first corrugated mesh panel 202 and the second corrugated mesh panel 302, thereby improving the heat dissipation effect.

[0045] Furthermore, a first guide rail portion (not shown in the drawings) is provided on the lateral side wall of one of the first frame 201 and the second frame 301, and a second guide rail portion (not shown in the drawings) that meshes with the first guide rail portion is provided on the lateral side wall of the other. So that the second cover 3 can slide smoothly along the first guide rail portion or the second guide rail portion, and under the limiting effect of the mutual limitation between the first guide rail portion and the second guide rail portion, the second cover 3 can be prevented from separating from the first cover 2 during the flipping process of the first cover 2. In this embodiment, the first guide rail portion can be a chute, and the second guide rail portion is a slider inserted into the chute for sliding, and the present application does not limit this.

[0046] In order to be able to fix the second cover 3 at a preset retracted position, the first cover 2 is further provided with a first fixing structure, and the second cover 3 is further provided with a second fixing structure. The second cover 3 is arranged to be able to slide between a retracted position and an extended position. Thus, in the retracted position, the first fixing structure and the second fixing structure can be fixedly connected to fix the first cover 2 and the second cover 3. In this embodiment, the first fixing structure and the second fixing structure can be a snap-fit assembly that cooperates with each other, or a pin hole and a pin shaft that are inserted and matched, as long as it can achieve the quick detachable connection between the second cover 3 and the first cover 2, and the present application does not limit this.

[0047] In one embodiment, as Figure 1As shown, the radiator cover includes a gas spring 4 whose two ends are respectively hinged to the first cover body 2 and the cover body main body 1. Specifically, when opening the radiator cover, that is, when flipping the first cover body 2 upward, the gas spring 4 can automatically change from the compressed state to the extended state, thereby driving the first cover body 2 to flip upward until the gas spring 4 extends to the maximum elongation or extends to a preset length, thus saving the effort of opening and closing the cover body, and at the same time playing a role of positioning and supporting the overall opening and closing of the cover body. When closing the radiator cover, that is, when flipping the first cover body 2 downward, the gas spring 4 can return from the extended state to the compressed state, so that the opening and closing cover body closes the cover opening.

[0048] In one embodiment, as Figure 1 shown, on one side of the first cover body 2 facing the cover body main body 1, there is a condenser installation position for installing the air conditioner condenser 5, and the cover body main body 1 is provided with a pipeline through hole for the air conditioner pipeline to pass through to connect the air conditioner condenser 5. Among them, the thickness of the cover body main body 1 is relatively large, and the formed cover cavity can not only accommodate the radiator, but also accommodate the air conditioner condenser 5. Therefore, by installing the air conditioner condenser 5 at the condenser installation position of the first cover body 2, when the first cover body 2 flips and closes the cover body main body 1, it can drive the air conditioner condenser 5 into the cover cavity.

[0049] In other words, in this embodiment, the air conditioner condenser 5 is arranged inside the radiator cover, and the originally independently arranged air conditioner condenser 5 is changed to a non-independent heat dissipation condenser, so that the air conditioner condenser 5 can use the fan that originally only assisted the radiator for heat dissipation, thereby reducing the design cost of the air conditioner condenser 5, and also effectively preventing the air conditioner condenser 5 from being blocked by foreign objects by using the wrapping effect of the radiator cover.

[0050] In one embodiment, the radiator cover further includes a buffer strip arranged between the cover body main body 1 and the opening and closing cover body, so as to avoid direct collision with the cover body main body 1 when closing the opening and closing cover body, reduce the risk of damage, and also play a sealing role. Among them, a sponge strip can be selected as the buffer strip, or a buffer member made of a buffer material such as a rubber strip can be used as the buffer strip, and this application does not limit this.

[0051] Furthermore, referring to Figure 1 , a buffer pad 13, such as a sponge pad, can also be arranged between the first cover body 2 and the second cover body 3, so that when the second cover body 3 contacts the first cover body 2, for example, when unfolding the opening and closing cover body to close the cover body main body 1, it can effectively prevent the second cover body 3 from colliding with the first cover body 2 and being damaged. Specifically, the first cover body 2 can be arranged on the outer peripheral wall of the top of the second cover body 3, or on the outer peripheral wall of the bottom of the first cover body 2, or both can be arranged, and this application does not limit this.

[0052] In one embodiment, as Figure 1As shown, a lifting structure 6 for hoisting is provided on the outer peripheral wall of the housing body 1, which facilitates the disassembly and assembly of the radiator housing. A first locking structure 7 is provided on the outer peripheral wall of the housing body 1, and a second locking structure 8 that can be detachably connected to the first locking structure 7 is provided on the outer peripheral wall of the opening and closing cover body. Among them, the first locking structure 7 can be a clamping seat as shown in the attached drawing, and the second locking structure 8 is a clamping head. Thus, when the opening and closing cover body is flipped downward, the first locking structure 7 and the second locking structure 8 can be locked with each other, so that the housing body 1 can be closed. When opening, only the connection between the first locking structure 7 and the second locking structure 8 needs to be unlocked, which is convenient and fast.

[0053] In one embodiment, a drain hole is formed through the bottom wall of the housing body 1, so that rainwater and the like can be automatically discharged from the housing body 1, effectively preventing problems such as rust on the radiator housing. In this embodiment, a plurality of drain holes can be provided, and the plurality of drain holes can be evenly distributed at the bottom of the housing body 1, so as to enhance the drainage capacity.

[0054] The second exemplary embodiment of the present application provides an agricultural machine, which includes the above-mentioned radiator housing. Obviously, the agricultural machine in this exemplary embodiment has all the technical effects brought by the above-mentioned radiator housing, so it will not be elaborated here.

[0055] It should be noted that in the present application, unless otherwise stated, the orientation words such as "upper and lower" generally refer to the upper and lower directions under the visual angle of the attached drawing.

[0056] After installing the radiator housing of the present application on the agricultural machine, when the agricultural machine is working, as Figure 1 shown, air can be sucked into the radiator housing by the fan. During this process, the air sequentially passes through the corrugated mesh plate of the opening and closing cover body, the air conditioner condenser and the radiator. When the radiator housing needs to be opened, the connection between the first locking structure 7 and the second locking structure 8 is disconnected, and the first cover body 2 can be manually pushed outwards. The gas spring 4 starts to stretch and pushes the first cover body 2 to flip upwards. The second cover body 3 always remains in a hanging state under the action of gravity, avoiding interference with the outer cover of the whole machine. When the gas spring 4 reaches the limit of the stretching stroke, the first cover body 2 opens to the limit position and remains stationary, so that it is convenient for the operator to clean and repair the inside of the housing. After completion, the first cover body 2 can be manually pressed downwards to compress the gas spring 4 until the first cover body 2 and the second cover body 3 return to the state of straight docking, and finally the first locking structure 7 and the second locking structure 8 are locked to complete the closing of the radiator housing.
