[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1 As shown, Figure 1 What is shown is a schematic diagram of the entirety (outer side) of the protective cover in the embodiment;

[0025] The device includes:

[0026] Back cover 10;

[0027] Front cover 20;

[0028] The connecting component is arranged at the connecting end of the rear cover 10 and the front cover 20. The front cover 20 is movably connected to the rear cover 10. The rear cover 10 and the front cover 20 are jointly covered on the material cutting mechanism. The front cover 20 can be lifted up alone to expose the part covered by the front cover 20.

[0029] By means of the connecting assembly, the integral cover body is arranged into a rear cover 10 and a front cover 20 which are movably connected. While playing a protective role, the front cover 20 can be opened separately to repair or maintain the cutting mechanism protected inside. Compared with opening the entire cover body, the process is labor-saving and occupies less space. It is more flexible and convenient to choose to open only the front cover 20 or to turn up the rear cover 10 together according to the actual situation.

[0030] like Figure 2 , Figure 3 As shown, Figure 2 What is shown is a schematic diagram of the entirety (inside) of the protective cover in the embodiment; Figure 3 It shows Figure 2 A schematic diagram of the structure enlargement in the middle;

[0031] The connecting assembly includes a shaft 32 and a hole 31. The shaft 32 is disposed on one end of the rear cover 10 close to the front cover 20. Both ends of the shaft 32 extend to both sides. The holes 31 are provided on the front cover 20 at positions corresponding to both ends of the shaft 32. Both ends of the shaft 32 pass through the holes 31 on the corresponding sides and are movably connected to the holes 31.

[0032] The front cover 20 and the rear cover 10 are movably connected by the cooperation between the shaft 32 and the hole 31 .

[0033] An installation end 11 is provided on one end of the rear cover 10 away from the front cover 20 , and the installation end 11 is hingedly connected to the device body.

[0034] The mounting end 11 is used for stable mounting of the rear cover 10 and can be lifted up under a certain external force.

[0035] It also includes a positioning seat 33 and a fixing plate 34, which are respectively fixedly arranged at one end of the rear cover 10 and the front cover 20 close to each other. A limiting rod 35 is hingedly arranged on the positioning seat 33, and the other end of the limiting rod 35 passes through the fixing plate 34 and is provided with a limiting end 36 with a diameter greater than that of the limiting rod 35 at the end, and a spring 37 is also sleeved between the limiting end 36 and the fixing plate 34.

[0036] Two ends of the spring 37 are fixedly connected to the fixing plate 34 and the limiting end 36 respectively.

[0037] A movable limit rod 35 is provided to guide and limit the front cover 20 when it is opened, thereby ensuring that the position of the front cover 20 does not shift when it is opened and limiting the opening angle. When the front cover 20 is opened by an external force, the limit rod 35 is driven to rotate at one end close to the positioning seat 33, and the spring 37 is compressed at the same time. The structure can also control the force required to open the front cover 20, thereby preventing the front cover 20 from being lifted up when a small force is applied during the walking and working process of the corn harvester, thereby ensuring that the daily protection status of the front cover 20 and the rear cover 10 is normal.

[0038] like Figure 4 As shown, Figure 4 What is shown is a schematic diagram of the connection between the limiting rod and the positioning seat in the embodiment.

[0039] The positioning seat 33 includes a cavity 331 , and the limiting rod 35 includes a T-shaped matching end 351 , which is rotatably disposed in the cavity 331 .

[0040] The arrangement of the matching end 351 and the cavity 331 realizes a movable connection between the limiting rod 35 and the positioning seat 33 .

[0041] Working principle: This device is covered on the cutting mechanism during the normal working process of the corn harvester to protect the cutting mechanism. During the daily maintenance and repair of the cutting mechanism, the front cover 20 or the front cover 20 and the rear cover 10 can be manually lifted up according to the specific part to be repaired to expose the part that needs repair and maintenance. Compared with the integral protective cover, it is more flexible.

[0042] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
