[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. By setting up a filter screen, it is possible to effectively prevent straw fragments from coming into contact with the engine, avoiding straw from falling on the surface of high-temperature engine parts and causing a straw fire. By pressing down the handle, the limiting post is driven into the sliding hole, which facilitates the protrusion into the limiting groove, and then the filter screen is quickly snapped into the inside of the mounting plate. Releasing the handle, the spring pushes the limiting post into the limiting hole, completing the fixation of the filter screen, which is convenient for installing and replacing the filter screen.
[0013] 2. By pushing the baffle, the engagement between the fixed wheel 2 and the fixed tooth 2 can be disengaged, allowing the baffle angle to be freely adjusted to cope with different weather conditions. At this time, the baffle pushes the movable ring to move towards the sleeve and compresses the spring 2. After the angle adjustment is completed, the baffle is released, the spring 2 pushes the movable ring away from the sleeve, and the movable ring pushes the fixed tooth 2 to re-engage with the fixed wheel 2, thus locking the baffle angle.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0025] like Figures 1-5As shown, a protective engine cover includes a protective cover 1. Connecting plates 101 are fixedly connected to both sides of the protective cover 1. Bolts 102 are threaded into the connecting plates 101, allowing the protective cover 1 to be connected to the engine. Mounting plates 2 are fixedly connected to the inner walls of both sides of the protective cover 1. The mounting plates 2 support the filter screen 3, while maintaining a certain distance from the sides of the protective cover 1, ensuring that the filter screen 3 can still dissipate heat even when the baffle 703 is fully lowered, preventing engine overheating. The mounting plates 2 are inverted T-shaped, dividing the sides of the protective cover 1 into two areas, ensuring the required filter screen 3 is of appropriate size for easy installation and replacement. A slot 201 is provided at the bottom of the side of the mounting plate 2 away from the protective cover 1, and a limiting groove 202 is provided in the middle of the side of the mounting plate 2 away from the protective cover 1. The filter screen 3 is snapped into the mounting plate 2, blocking straw fragments and dust, providing protection for the engine.
[0026] A locking block is fixedly connected to the bottom of the filter screen 3 at a position corresponding to the slot 201. A protrusion 301 is fixedly connected to one side of the filter screen 3 at a position corresponding to the limiting groove 202. A limiting hole 302 is opened through the protrusion 301. The filter screen 3 and the mounting plate 2 can be quickly locked together by the cooperation of the locking block and the slot 201, and the protrusion 301 and the limiting groove 202.
[0027] The inner wall of the limiting groove 202 is provided with two sets of sliding holes 203. The two sets of sliding holes 203 are slidably connected to the limiting posts 303. The two sets of limiting posts 303 are fixedly connected to the outside of the two sets of limiting posts 303. The lifting handles 304 can connect the two sets of limiting posts 303, so as to fix the two sets of filter screens 3 at the same time. A spring 305 is provided inside the sliding hole 203. One end of the spring 305 is fixedly connected to the bottom end of the sliding hole 203, and the other end of the spring 305 is fixedly connected to the bottom end of the limiting post 303.
[0028] When installing filter screen 3, first pull down handle 304. Handle 304 will move the two sets of limiting posts 303 down simultaneously until the two sets of limiting posts 303 are fully inserted into the corresponding two sets of sliding holes 203. Then, align the protrusion 301 of filter screen 3 with the limiting groove 202 and insert it. After the insertion is complete, release handle 304. Spring 305 will push the limiting post 303 up and insert it into the limiting hole 302, thus fixing filter screen 3. When replacing or cleaning filter screen 3, pull down handle 304 to move the limiting post 303 away from the limiting hole 302, releasing the fixing of filter screen 3. Then filter screen 3 can be removed. The operation is convenient.
[0029] Both sides of the top of the protective cover 1 are fixedly connected to sleeves 4. The sleeves 4 are rotatably connected to a rotating shaft 7. The rotating shaft 7 can drive the baffle 703 to rotate, and adjust the angle of the baffle 703 to adapt to the protection requirements of different weather. The rotating shaft 7 is provided with fixing components at both ends. The fixing components include fixing tooth 1 701 and fixing tooth 2 702. Fixing tooth 1 701 and fixing tooth 2 702 are respectively fixedly connected to both ends of the rotating shaft 7. Both fixing tooth 1 701 and fixing tooth 2 702 are fixedly connected to the baffle 703.
[0030] The fixing assembly also includes a connecting ring 5. The connecting ring 5 is fixedly connected to one end of the sleeve 4 near the fixing tooth 702. The other end of the connecting ring 5 is fixedly connected to a spring 502. The other end of the spring 502 is fixedly connected to a movable ring 501. The movable ring 501 is sleeved on the outside of the rotating shaft 7 and can slide along the outside of the rotating shaft 7. The inner diameter of the connecting ring 5 and the movable ring 501 corresponds to the inner diameter of the sleeve 4.
[0031] The fixing assembly also includes a first fixing wheel 401 and a second fixing wheel 6. The first fixing wheel 401 is fixedly connected to one end of the sleeve 4 near the first fixing tooth 701. The second fixing wheel 6 is fixedly connected to the side of the protective cover 1 away from the first fixing wheel 401 and corresponding to the position of the first fixing wheel 401. Both the first fixing wheel 401 and the second fixing wheel 6 have multiple sets of tooth grooves. Both the first fixing tooth 701 and the second fixing tooth 702 have multiple sets of teeth fixedly connected to them. The teeth mesh with the tooth grooves. By meshing the teeth with the tooth grooves, the rotating shaft 7 can be locked at different angles, thereby locking the baffle 703 at different angles.
[0032] During operation, first connect the protective cover 1 to the engine using bolts 102. Then, pull down the handle 304, which causes the two sets of limiting posts 303 to move down simultaneously until they are fully engaged in the corresponding sliding holes 203. Next, align the protrusion 301 of the filter screen 3 with the limiting groove 202 and insert it. After engagement, release the handle 304. Spring 1 305 pushes the limiting post 303 upward and inserts it into the limiting hole 302, thus securing the filter screen 3. To replace or clean the filter screen 3, pull down the handle 304 to move the limiting post 303 away from the limiting hole 302, releasing the filter screen 3. The filter screen 3 can then be removed. The operation is convenient. Then, adjust the rotating shaft 7 according to the weather to adjust the angle of the baffle 703. When adjusting the rotating shaft 7, first push the fixed tooth 2 702 towards the movable ring 501. The movable ring 501 slides along the surface of the rotating shaft 7, compressing the spring 2 502. Fixed teeth 701 and 702 disengage from fixed wheels 401 and 6 respectively, allowing the shaft 7 to rotate inside the sleeve 4. The rotation of the shaft 7 drives the baffle 703 to rotate. In rainy or snowy weather, the baffle 703 is rotated to be parallel to the mounting plate 2 to prevent rain and snow from entering the engine through the filter screen 3 and causing damage. In sunny weather, the baffle 703 is rotated to be perpendicular to the mounting plate 2 to facilitate ventilation and heat dissipation of the filter screen 3. After the angle is adjusted, the teeth of fixed teeth 702 are aligned with the tooth grooves of fixed wheels 6. Under the push of spring 502, the teeth of fixed teeth 702 engage with the tooth grooves of fixed wheels 6. At the same time, fixed teeth 701 and fixed wheels 401 at the other end of the shaft 7 also engage synchronously, locking the angle of the shaft 7 and thus locking the angle of the baffle 703. This facilitates handling different weather conditions and improves the applicability of the device.
