Description

Mulching Apparatus Having Variable Structure}

The present invention relates to a mulching device including a variable structure, and more specifically, to a mulching device including a variable structure capable of performing a mulching operation on the upper surface of a raised bed in various sizes.

In general, seedling and transplanting farming methods allow for consistent and relatively high yields compared to direct sowing, which involves sowing seeds directly into farmland, and are therefore applied to many farms, including rice farming. In particular, seedling and transplanting methods are adopted for more than 90% of rice farming.

However, seedling and transplanting work requires a lot of labor and is becoming increasingly difficult in rural areas where the population is aging, so the need for direct seeding that does not require seedling or transplanting is rapidly increasing. In addition, mulching film provides weed control, insulation, and moisturizing functions, making it an essential agricultural material for farmers who want to produce high-quality agricultural products and produce high yields.

In light of the current rural reality where labor problems are intensifying, the seedling and transplanting stages can be replaced with direct seeding and the laying of mulching film can be done at the same time, resulting in significant labor savings. With the idea that a significant amount of labor can be saved, a seed film (seed film attached to the mulching film) The use of Mulching Film with Seed is gradually increasing, and the need for equipment to spread seed film is also increasing.

Prior Art Patent Registration No. 10-1254462 is “a seed film laying device installed at the rear end of agricultural machinery such as a riding spreading device, rice transplanter, tractor, cultivator or manager, a frame provided at the rear end of the agricultural machinery; a seed film is wound; , a seed film holder installed on the upper side of the frame; a flat plate provided on the lower side of the frame, the longitudinal direction of which is parallel to the plane direction of the paddy field floor, and evenly leveling the paddy field floor on which the seed film is to be laid; the bacteria A seed film pressurizing unit that is spaced apart from the flat plate at a specific interval and is provided on the rear side of the flat plate to press the seed film spread on the bottom of the paddy field by rotation of the seed film holding unit; And is spaced at a specific interval from the seed film pressurizing unit. It includes a wheel-shaped seed film fixing part that is provided on the rear side of the seed film pressing part and presses and fixes both ends of the pressurized seed film, wherein the balanced plate has a concave rearward curved formation, and the balanced plate It further comprises a control unit that rotates the control unit based on the longitudinal axis of the level plate, a sensor that detects the height and strength of the paddy field, and a control unit that controls the control unit based on data detected by the sensor. “Seed film placement device.”

As seen in the prior art, mulching film is easily peeled off by the wind due to its nature, so when mulching, it must be covered with soil to fix the film to the ground. However, manual work requires a lot of labor, so the power of the tractor and the agricultural rotary must be used as dirt rain. There have been many attempts to cover the soil by using it as a birthplace. Figure 1 shows a side configuration diagram of a conventional soil mulching device having a soil scattering unit.

Structurally, the position of the tillage blade of the agricultural rotary that scatters soil is located below the roll-type mulching film, so the mulching film may be damaged by the scattering soil, so a mulching film protective cover must be installed to protect the mulching film. By doing this, the scattered soil can pass over the mulching film protective cover in a parabolic curve and reach the mulching film.

In the case of a soil mulching device having only a soil scattering portion according to the prior art shown in FIG. 1, there is a problem in that a soil wall is formed inside the device.

Moreover, in the case of the mulching device according to the prior art, it is a structure that is tied to and towed at the rear end of a large equipment of a tractor. In order to check whether the mulching state is progressing stably during the mulching process, the rear end in the opposite direction to the moving direction of the tractor is used. There is a problem that needs to be looked back on.

Therefore, there is a need for a technology that can solve the problems caused by the prior art mentioned above.
