Description

Technical Field

[0001] The utility model relates to the field of improvement of agricultural machinery, in particular to an improved soil turning and covering composite device suitable for agricultural machinery. Background Art

[0002] As a traditional agricultural country, my country has implemented the household contract responsibility system since the 1970s. The development of agriculture is closely linked to the interests of farmers. However, due to the accelerating urbanization process in my country, most young and middle-aged people in mountainous areas have turned to work in cities, resulting in a shortage of rural labor.

[0003] As the population settles in urban areas and the rural population declines, land abandonment (the phenomenon of suitable land being left idle and uncultivated) has emerged. To effectively address this issue, ensure production efficiency, and increase crop yields, existing technologies utilize agricultural machinery and equipment to replace traditional manual agricultural labor. This saves labor while more effectively utilizing resources and reducing the labor burden on agricultural workers. Agricultural development is of great significance to the transformation and upgrading of my country's agricultural industry. If crop yields and quality can be significantly improved, it will help ensure my country's food security and promote rural revitalization.

[0004] However, existing small agricultural machinery still faces several challenges: insufficient versatility, long periods of idle time, and limited crop production. This results in single-type agricultural equipment having short operating times and spending the majority of its time idle. This idle machinery not only fails to fully utilize its capabilities, resulting in equipment waste, but also requires additional maintenance during its idle period. Improper maintenance can lead to rust and malfunctions, potentially rendering it unusable the following year. This makes some machinery consumable, requiring repeated purchases and repairs, resulting in poor economic returns.

[0005] Furthermore, regarding the lack of versatility, most existing small agricultural machinery cannot fully adapt to different environmental and working conditions, and cannot freely switch between different functional requirements. Different agricultural machinery is often required to complete the work, resulting in poor efficiency during plowing and sowing. For example, in late autumn and early winter, or before spring plowing, soil turning is often required, while soil covering is required after the crops are planted. The former requires appropriate tools and controlled soil depth, while the latter requires a tight burial, without exposed roots, branches, or loose soil covering. With existing technology, these two operations require different tools and machinery, resulting in insufficient versatility and long periods of idle time. Utility Model Content

[0006] In summary, after analyzing and redesigning existing agricultural machinery, the present invention provides a soil turning and covering composite device suitable for agricultural machinery, which combines the soil turning function and the soil covering function in the same module to achieve a multifunctional working mode of a single module. The present invention is easy to install or disassemble and can be adapted for use with a variety of agricultural machinery currently on the market. The present invention is a soil turning and covering composite device suitable for agricultural machinery, and its specific structure is as follows:

[0007] A soil turning and covering composite device suitable for agricultural machinery includes an agricultural operation vehicle that can travel in the field, and is characterized by:

[0008] The agricultural vehicle is fixed with an L-shaped connecting plate at both ends of the front of the vehicle, and a cantilever bracket is fixed on the horizontal plate surface above the connecting plate, that is, there are two cantilever brackets in total, and they are arranged in the same direction;

[0011] The electric push rod design here controls the lifting height position of the soil-turning and covering composite component, making its distance from the ground adjustable to ensure its contact with the ground.

[0012] One of the extension sections is provided with a drive motor at the tail position near the connecting plate. The drive end of the drive motor passes through the extension section horizontally, and a transmission chain is sleeved on the drive end. The other end of the transmission chain is connected to the soil turning and covering composite component.

One end of the transmission hexagonal shaft is sleeved with a transmission gear, which is engaged with the transmission chain. The driving end of the drive motor drives the transmission chain to transmit torque to the transmission hexagonal shaft, the central gear and the soil turning and covering composite claw.

[0015] There are 6 to 8 center gears in total. The center of the center gear has a hexagonal through hole corresponding to the size of the shaft of the transmission hexagonal shaft. Each center gear is sequentially sleeved on the transmission hexagonal shaft and fixed. That is, the transmission hexagonal shaft can drive the center gear to rotate.

[0016] The number of the soil-turning and covering composite claws corresponds to the number of the central gears. Each soil-turning and covering composite claw is composed of four gear claws, which are connected to the central gear through gear claw connecting holes and meshed with the central gear.

[0017] According to the utility model, a soil-turning and covering composite device suitable for agricultural machinery is characterized in that the right side of the gear claw is an arcuate surface and the left side is a rack surface, and the rack surface is meshed with the center gear; when the transmission hexagonal shaft rotates clockwise, the arcuate surface on the right side of the gear claw first contacts the soil, and the rack surface on the left side of the gear claw after being subjected to force engages with the center gear in the positive direction, and the four gear claws are retracted inward to form a circular soil-turning and covering composite claw part for soil covering operation; and when the transmission hexagonal shaft rotates counterclockwise, the tip of the gear claw first contacts the soil, and the rack surface on the left side of the gear claw after being subjected to force engages with the center gear in the reverse direction, and the four gear claws are expanded outward to form a windmill-shaped soil-turning and covering composite claw part for soil turning operation.

[0018] Since the electric push rod can control the distance between the soil-turning and covering composite components and the bottom surface, the depth of soil turning can be controlled, maintaining consistency within the soil turning operation time.

[0019] According to the utility model, a soil turning and covering composite device suitable for agricultural machinery is characterized in that the driving motor can rotate forward or reverse, and drives the soil turning and covering composite claw of the soil turning and covering composite assembly to rotate clockwise or counterclockwise through the transmission chain.
