[0022] In order to make the technical means, creative features, achieved objectives and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0023] Embodiment:

[0024] Please refer to Figure 1 - Figure 4 , a corn straw end crushing device, including an outer structure cover 1 of the crushing device. A rotatable transmission assembly 2 is arranged inside the outer structure cover 1 of the crushing device. Transmission disks 3 are fixed on the surfaces of both ends of the part of the transmission assembly 2 located inside the outer structure cover 1 of the crushing device. A corresponding number of transmission rods 4 are fixed on the surfaces of the two groups of transmission disks 3. A crushing plate 5 that can move relative to the transmission rods 4 is installed between the two groups of transmission rods 4;

[0025] The transmission assembly 2 drives the crushing plate 5 to rotate through the transmission disks 3 and the transmission rods 4. A crushing area is formed during the rotation of the crushing plate 5, and the end of the corn straw is crushed after entering the crushing area.

[0026] The transmission assembly 2 includes a transmission shaft 21 and a transmission wheel 22. The transmission shaft 21 is installed inside the outer structure cover 1 of the crushing device through bearings. The transmission disk 3 is installed on the surface of the transmission shaft 21. The transmission wheel 22 is installed at the end of the transmission shaft 21. The transmission wheel 22 is connected to an external power component, receives external power input and drives the transmission shaft 21.

[0027] The transmission rod 4 is designed in a "C" shape. A cross bar for the crushing plate 5 to be sleeved and connected is connected between the two groups of transmission rods 4. The crushing plate 5 can move within the range of the transmission rod 4 with the cross bar as the axis. The crushing plate 5 has a "T" - shaped structure. The vertical part of the crushing plate 5 extends into the transmission rod 4 so that the movement of the crushing plate 5 is limited by the transmission rod 4. The crushing plate 5 rotates at a high speed driven by the transmission rod 4. When the crushing plate 5 hits hard straw or sundries during rotation, the crushing plate 5 can rotate relative to the transmission rod 4 to avoid collision, preventing damage to the crushing plate 5 due to rigid connection.

[0028] The transverse part of the crushing plate 5 is designed in an arc shape. The arc design enables the crushing plate 5 to have a smooth transition when touching the ground. The end of the transverse part of the crushing plate 5 is designed with an inclined chamfer. The chamfer design enables the crushing plate 5 to form a cutting part during rotation. The cutting part can easily break the straw without forming a smooth cross - section again.

[0029] A protective component 6 is also provided inside the outer structure cover 1 of the crushing device. The protective component 6 shields the crushing area. The protective component 6 includes an outer fixed baffle 61 and an inner movable baffle 62. The outer fixed baffle 61 is provided on one side of the outer structure cover 1 of the crushing device at a parallel position relative to the transmission component 2. The inner movable baffle 62 is sleeved in the outer fixed baffle 61 and fixed in the outer fixed baffle 61 by friction. After the outer structure cover 1 of the crushing device is placed horizontally to enter the working state, according to the direction of the outer structure cover 1 of the crushing device when it is installed, the inner movable baffle 62 can be pulled out from the outer fixed baffle 61 by pulling on both sides. The inner movable baffle 62 after being pulled out serves as an extension of the outer fixed baffle 61 to further shield the crushing area formed by the crushing plate 5, thereby ensuring the safety of the crushing plate 5 when rotating.

[0030] A connecting joint 7 is provided on one side of the outer structure cover 1 of the crushing device, and a connecting hole for connecting to an external device is provided in the connecting joint 7. The outer structure cover 1 of the crushing device can be fixed to the end of the straw harvesting equipment through the connecting joint 7. After the straw harvesting equipment passes by, the end of the straw is directly crushed.

[0031] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
