Both the fuel tank 4 and the drum transmission box 5 are arranged inside the open assembly tail cover. Since the tail cover is of an open structure, ventilation is convenient, and the heat dissipation effect of heat-generating devices (such as the fuel tank 4 and the drum transmission box 5) is greatly enhanced. The open assembly tail cover includes a first side wall plate 1, a second side wall plate 2, and a tail cover main body 3.

[0028] In the following description, reference will be made to Figures 1 to 3 specifically describe the detailed structures of the first side wall plate 1, the second side wall plate 2, and the tail cover main body 3 of the open assembly tail cover.

[0029] As Figure 1 and Figure 2As shown, in the embodiment, the tail cover body 3 is the main structure of the open assembly tail cover, and the first side wall plate 1, the second side wall plate 2, the fuel tank 4 and the roller transmission box 5 are all installed on the tail cover body 3. The tail cover body 3 can be formed into a frame structure, and the frame structure is assembled by a plurality of cross bars and a plurality of vertical bars, so that the tail cover body 3 can be ventilated conveniently, thereby enhancing the heat dissipation effect of the fuel tank 4 and the roller transmission box 5 located inside the tail cover body 3. Specifically, the fuel tank 4 and the roller transmission box 5 are both arranged inside the tail cover body 3, and the tail cover body 3 can be fixedly connected with the fuel tank 4 and the roller transmission box 5 by opening screw holes and matching fastening bolts. The first side wall plate 1 and the second side wall plate 2 are arranged at the lower part of the two ends of the tail cover body 3, and the first side wall plate 1 and the second side wall plate 2 can protect the lower part of the fuel tank 4 and the roller transmission box 5, and at the same time increase the ventilation effect. The first side wall plate 1 and the second side wall plate 2 surround the two ends of the fuel tank 4 and the two ends of the roller transmission box 5, and the two ends here can be understood as the left and right ends.

[0030] The open assembly tail cover surrounds the fuel tank 4 and the roller transmission box 5 through the first side wall plate 1, the second side wall plate 2 and the tail cover body 3. At the same time, the tail cover body 3 formed into a frame structure can facilitate overall ventilation, thereby enhancing the ventilation effect, ensuring the heat dissipation requirements, reducing the probability of damage to the fuel tank 4 and the roller transmission box 5, and improving the performance of the whole machine. In addition, since the first side wall plate 1, the second side wall plate 2 and the tail cover body 3 are assembled structures, the problem of difficulty in assembly of the overall structure is solved, and it is also convenient for later maintenance.

[0031] Preferably, if Figure 1 and Figure 2 As shown, in the embodiment, the tail cover body 3 may include a first surrounding portion 301, a second surrounding portion 302, a first connecting bracket 303 and a second connecting bracket 304, the first connecting bracket 303 and the second connecting bracket 304 are respectively arranged at the lower parts of the first surrounding portion 301 and the second surrounding portion 302, and the first surrounding portion 301 and the second surrounding portion 302 are respectively arranged at both ends of the fuel tank 4. The first surrounding portion 301 and the second surrounding portion 302 may both be formed into a frame structure and are arranged at both ends of the fuel tank 4, the first surrounding portion 301 and the second surrounding portion 302 may serve as the main structure of the tail cover body 3, not only to protect the fuel tank 4, but also to facilitate ventilation, and at the same time facilitate the installation of the first connecting bracket 303 and the second connecting bracket 304.

[0032] Preferably, if Figure 1 and Figure 2As shown, in the embodiment, the first side wall plate 1 and the second side wall plate 2 are detachably connected to the first connecting bracket 303 and the second connecting bracket 304 respectively. The first connecting bracket 303 and the second connecting bracket 304 can both be U-shaped steels. Multiple threaded holes are provided on both sides of the U-shaped steel.

When crop straws and dust fall on the first side wall plate 1 and the second side wall plate 2, the crop straws and dust will slide down along the grass guiding plates 9.

[0040] The open assembly tail cover first encloses the fuel tank and the drum transmission box through the first side wall plate, the second side wall plate and the tail cover main body. At the same time, the overall ventilation is convenient through the tail cover main body formed into a frame structure, thereby enhancing the ventilation effect, ensuring the heat dissipation requirements, reducing the damage probability of the fuel tank and the drum transmission box, and improving the performance of the whole machine. Secondly, since the first side wall plate, the second side wall plate and the tail cover main body are of an assembled structure, the problem of difficult assembly due to the large overall structure is solved, and it is also convenient for later maintenance, reducing the burden on the staff.

[0041] In addition, according to a second aspect of the present utility model, a harvester is provided, and the harvester includes the open-type assembly tail cover as described above. During the use of the harvester, by being equipped with the open-type assembly tail cover, the heat dissipation capacity of the heating device can be enhanced, the normal operation of the harvester can be ensured, and the heating device can also be prevented from being damaged due to excessive heat.

[0042] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them.
