[0025] like Figure 1-2As shown, in one embodiment of the utility model, a corn stalk crushing device comprises a first conveyor belt 1, a segmentation assembly 2, a second conveyor belt 3, a vibrating screen 4, a third conveyor belt 5 and a crusher 6 connected in sequence from left to right, wherein the first conveyor belt 1 is provided with a height limiting member 7, the second conveyor belt 2 is provided with a first material shifting member 8, and the third conveyor belt 5 is provided with a second material shifting member 9. Corn stalks are fed from the left end of the first conveyor belt 1 to the right, and are limited by the height limiting member 7, which, on the one hand, maintains a stable conveying amount, and on the other hand, is conducive to subsequent segmentation. After the corn stalks are transported to the segmentation assembly 2, they are cut into stalk segments and enter the second conveyor belt 3 for further transportation, and the first material shifting member 8 shifts the material, so that the stalk segments can be uniformly entered into the vibrating screen 4 for vibration and impurity removal, and the impurity-removed stalk segments enter the third conveyor belt 5 for further transportation, and after being shifted again by the second material shifting member 9, they are uniformly entered into the crusher 6 for crushing, and the overall crushing effect is good, the efficiency is high, and the damage of the crusher can be avoided.

[0026] In this embodiment, in order to improve the vibration cleaning effect, the vibration screen 4 is arranged to be tilted downward from left to right, and the tilt angle is 10-15°.

[0027] In this embodiment, the height limiting member 7 includes vertical rods (not marked in the figure) arranged on both sides of the first conveyor belt and height limiting plates (not marked in the figure) mounted on the two vertical rods, which are used to control the conveying amount of corn stalks and facilitate the subsequent cutting process.

The output end of the cutting lifting driver 26 is connected to a cutting machine 27 located under the lifting platform 25. A avoidance hole 29 is provided on the table of the support frame 21 corresponding to the position of the cutting machine 27. Both left and right ends of the lifting platform 25 are provided with a straw pressing piece 28. During operation, the integral lifting driver 24 drives the lifting platform 25 to move down to the straw pressing piece 28 to press the two ends of the corn stalk. At this time, the cutting lifting driver 26 drives the cutting machine 27 downward to cut the corn stalk, and returns to its position after the cutting is completed, and continues the next segment cutting. Through the structure of the cutting component 2, the corn stalks can be cut into segments stably and efficiently, which is beneficial for subsequent crushing.

[0030] In another preferred embodiment, in order to improve the cutting stability of the cutting assembly 2, the front and rear ends of the lifting platform 25 can be movably connected to the front and rear support rods 22 respectively. When the lifting platform 25 is driven by the integral driver 24 to move up and down, the two ends of the lifting platform 25 can move up and down along the support rods 22.

[0031] In this embodiment, baffle plates 10 are provided on both sides of the first conveyor belt 1, the second conveyor belt 3, the cutting assembly 2, the vibrating screen 4 and the third conveyor belt 5. The baffle plates 10 can improve the conveying effect of corn stalks and prevent corn stalks from falling.

[0032] In a more preferred embodiment of the present invention, the first conveyor belt 1 is a roller conveyor belt having gaps therein, which is conducive to the stones and the like on the corn stalks falling from the gaps during the transportation of the corn stalks.

[0033] In a more preferred embodiment of the present invention, the right end of the vibrating screen 4 is connected to a magnet block (not shown in the figure), which can absorb iron impurities in the corn stalks and further improve the impurity removal effect.

[0034] To sum up, the corn stalk processing device of the utility model has a simple overall structure, is easy to operate, has uniform material feeding and few impurities, can effectively improve the efficiency and effect of corn stalk crushing, and is highly practical.
