Function

• Mulching Function: It can cover films on various crops that allow mulching, such as potatoes, peanuts, cotton, corn, watermelons, and medicinal materials. Mulching can increase the soil temperature, retain water, preserve soil and fertilizer, improve fertilizer efficiency, and also has the functions of weed control, pest and disease prevention, drought resistance and waterlogging prevention, salt suppression and seedling protection, and improving the near - ground light and heat conditions.
• Pesticide Spraying Function: The machine is equipped with an electric sprayer device. During the mulching process, it can spray herbicides, insecticides, and other pesticides, achieving the integration of mulching and pest control in one operation, which is time - saving and labor - saving.

Structure

• Frame and Mounting Part: The frame is the main body of the machine, which provides support and stability for other components and is usually used to be connected to tractors or other power sources. The mounting part is used to install the mulching machine on the power source to ensure reliable connection and easy installation and removal.
• Mulching Film Laying Mechanism: It includes components such as a film - feeding roller, a film - spreading roller, and a film - pressing wheel. The film - feeding roller is used to hold the mulching film roll and release the film as the machine moves; the film - spreading roller spreads the film flat on the ground; the film - pressing wheel presses the two edges of the film into the soil to ensure that the film is tightly attached to the ground.
• Pesticide Spraying System: It is mainly composed of a medicine tank, a spray pump, a pipeline, and a spray head. The medicine tank is used to store pesticides; the spray pump pumps the pesticides in the medicine tank out and transports them to the spray head through the pipeline; the spray head sprays the pesticides evenly on the soil surface or crop leaves.
• Depth Control and Guidance Devices: Depth - control devices such as wheels or skids are used to control the depth of film laying and pesticide spraying to ensure that they meet the agronomic requirements. The guidance device is used to keep the machine moving in a straight line to ensure the uniformity and quality of mulching and spraying.

Types

• Hand - held Mulching Machines with Pesticide Sprayers: They are suitable for small - scale agricultural production or operations in areas with limited space. They are usually powered by 人力 or small - power engines and have the characteristics of flexibility and convenience, but their work efficiency is relatively low.
• Tractor - drawn Mulching Machines with Pesticide Sprayers: They are connected to tractors and use the power of tractors to drive. They have high work efficiency and can be used for large - area agricultural production. According to the connection method with tractors, they can be divided into three - point - hitch - type and front - mounted - type.

Working Principle

First, the power source (such as a tractor) drives the mulching machine to move forward. The leveler first levels the ridge surface, and then the ditcher turns the soil outward to open ditches on both sides of the ridge. Next, the spray heads located on both sides of the ridge top spray herbicides or other pesticides onto the ridge top and both sides. After that, the film spreading roller rolls to take the mulching film from the film roll and attach the middle part to the ridge back, and the two edges hang down along both sides of the ridge. The film - pressing wheel presses the film edges into the ditches, and finally, the covering device turns the soil dug out by the ditcher inward to bury and press the film edges.
