Description

Technical Field

[0001] The invention relates to the technical field of corn straw processing, and in particular to a self-propelled corn straw collecting and baling device. Background Art

[0002] Corn is simple to grow, offers high yields, and offers significant economic benefits. However, corn harvesting mechanization is less efficient than for wheat and rice. Furthermore, its straw is a versatile, renewable bioresource, useful as fertilizer, bio-oil, environmentally friendly industrial raw material, and feed. However, my country's straw utilization rate is low, with incineration being the primary method of disposal in the past. This inefficiency hinders wheat planting.

[0003] Corn straw is a dual-purpose crop used primarily as feed, both as a grain and cash crop. It is also a crucial resource for both industrial and agricultural production, rich in nutrients and bioavailable chemical components, making it a valuable raw material for livestock feed. Corn straw has long been a primary roughage source for livestock. It is also a valuable biomass energy resource within agricultural ecosystems. Annually, my country's agricultural production generates over 700 million tons of various straws, of which approximately 350 million tons are corn straw. Turning waste into valuable resources, efficiently and cost-effectively utilizing corn and other crop straw, is a key research and development focus in biomass resource utilization worldwide.

[0004] Corn straw has become a fuel for biomass power plants. To use corn straw as a fuel for power generation, the corn straw must first be transported from farmland to the plant, bundled, and stored. The plant then compresses the loose corn straw into neat blocks using hydraulic balers, which are then stacked into piles for future use. However, the compact stacking of corn straw blocks hinders ventilation and can lead to rotting over time. Furthermore, the straw is bulky and loose when transported from the field to the plant, resulting in low transportation efficiency. Therefore, it is particularly important to improve existing integrated corn straw collection and baling equipment by designing a new self-propelled corn straw collection and baling device to address these technical deficiencies and improve the overall practicality of the equipment.

When the straw is introduced above the connecting platform 4, the dust carried by the straw is adsorbed by the dust suction component 7 to prevent a large amount of dust from being generated during the work process. This setting will cause air pollution and will also cause certain damage to the health of the staff. At the same time, when the guide fan 11 guides the hot air, it can cooperate with the guide fan 11 to further guide the hot air, so that the hot air can pass smoothly between multiple groups of straw, effectively drying the straw, and preventing the corn straw from being compactly stacked for a long time and causing intermediate rot, affecting its use.
