Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a corn stalk returning to the field crushing equipment and crushing method. Background Technology

[0002] In the past, due to outdated technology and concepts, crop straw was often burned directly on the spot after harvest. This burning of straw by farmers not only caused numerous socio-economic and ecological problems such as air pollution, soil mineralization, and fire accidents, but also wasted the nutritional value of the straw itself. Further processing of straw requires its shredding. In northern my country's corn-producing areas, especially in areas with a two-crop rotation of wheat and corn, the high moisture content of corn straw at harvest makes it soft and easily deformed. This increases the workload of the shredder and makes it more prone to sticking to the internal parts, accelerating wear and tear and increasing the risk of blockages, thus affecting the normal operation of the equipment. Furthermore, when corn straw is crooked on the ridges and a large amount is returned to the field after shredding, some straw tends to accumulate in the shredding equipment, affecting the shredding effect and preventing the straw from being evenly distributed in the field.

[0041] This invention also provides a method for crushing corn stalks for returning to the field. The crushing method is applied to the aforementioned corn stalk returning to the field crushing equipment and includes the following steps:

[0042] Step S1: Install one end of the connecting frame 11 into the tractor, and place the multiple rows of ridges between the two end guide elements 21 and the four middle guide elements 22;

[0043] Step S2: Then start the tractor and use the tractor to push the corn stalk returning and crushing equipment to arrange, transport and soften the corn stalks on the rows;

[0044] Step S3: The crushing component 40 will crush the softened corn stalks.

[0045] For example, in one embodiment: a drive motor is provided at the bottom of the support frame 12, and the drive shaft 31 is connected to the output shaft of the drive motor.

[0046] For example, in one embodiment: when a crushing operation is required, a tractor pushes the corn stalk returning to the field to crush the corn stalks on multiple rows. When it comes into contact with the skewed corn stalks on the rows, the driven guide wheel 28 rotates, causing the driven guide shaft 27 to move inward along the driven guide cylinder 26. This allows the skewed corn stalks to be collected evenly side-by-side under the guidance of the driven guide wheel 28, guide plate 144, and guide collection inclined plate 121. Simultaneously, the drive motor starts, driving the drive shaft 31 to rotate and transmitting power through the first transmission belt to the six transmission wheels 33. Subsequently, the power is transmitted through the second transmission belt on the six transmission wheels 33 to the two connecting wheels 24 of the two end guide elements 21 and the four middle guide elements 22, causing them to rotate and arrange and convey the corn stalks that enter them. This ensures the uniformity of the stalk feed during subsequent crushing and prevents sudden accumulation that could affect the crushing effect.

[0047] Simultaneously, since the outer wall of the bonding wheel 292 is attached to the outer wall of the second transmission belt, when the second transmission belt is driven, the bonding wheel 292 will rotate synchronously, causing the primary crushing column 29 to rotate, and the striking roller 291 within it to rotate synchronously. This provides initial crushing and softening of the corn stalks, making subsequent crushing more uniform and convenient. At the same time, excess moisture in the corn stalks is knocked out. Subsequently, the softened corn stalks will enter between the inclined elastic plate 417 and the extrusion bar 414, and be further extruded by the inclined elastic plate 417 and the extrusion bar 414 to remove excess moisture, preventing blockages during subsequent crushing due to excessive moisture in the corn stalks.

[0048] When the drive motor drives the drive shaft 31 to rotate, its power is transmitted to the transmission shaft 421 along the fourth transmission belt, causing it to rotate. The fifth transmission belt 425 causes the crushing drive wheel 423 to rotate, which in turn causes the crushing roller 431 to rotate and crush the corn stalks.

[0049] For example, in one embodiment: when accumulation occurs during crushing, the accumulated portion will cause the inclined elastic plate 417 to deform and move outward, thereby pushing the two elastic sealing strips 419 to be compressed and deformed synchronously. Since the width of the inner end of the trigger slider 441 gradually decreases from the outside to the inside, the trigger slider 441 will slide outward along the trigger groove 416, thereby pushing the vertical trigger block 443 to slide downward, causing the rolling mounting plate 451 to rotate and tilt up, causing the rolling roller 453 to move accordingly, and causing the distance between the rolling roller 453 and the inclined elastic plate 417 to change synchronously, thereby squeezing and "kneading" the corn stalks at the crushing feed point, thereby evenly dispersing the corn stalks at the crushing feed point, preventing the continuous feeding of a large amount of corn stalks into the accumulation, which would lead to blockage.

[0050] Installation process: Install one end of the connecting frame 11 into the tractor, install the inner side of the support frame 12 onto the other end of the connecting frame 11, install the inner ends of the two end guide frames 13 onto the middle of the outer ends of the support frame 12, and install the inner ends of the two middle guide frames 14 along the length direction onto the middle of the outer side of the support frame 12 and between the two end guide frames 13.

[0051] This invention can achieve:

[0052] 1. This invention can effectively guide and uniformly collect skewed corn stalks, ensuring uniform feeding during subsequent conveying and crushing processes. It avoids uneven crushing or equipment blockage caused by uneven stalk accumulation, while maintaining high conveying and crushing efficiency. It can also effectively soften corn stalks and remove excess moisture, thereby achieving a more uniform crushing effect. This reduces the risk of failure caused by uneven load or overload, and improves the overall reliability and safety of the operation.

[0053] 2. This invention, by squeezing and kneading the piled straw, evenly disperses the straw, ensuring that the straw can enter the crushing zone evenly during the subsequent crushing process. This improves the crushing effect, reduces equipment overload or instability caused by accumulation, helps protect the equipment, enhances the overall stability and reliability of the operation, extends the service life of the equipment, and reduces the frequency and cost of maintenance and repair.

[0054] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
