Description

Technical field [0001] The invention provides an agricultural topdressing device, which is a topdressing device specially for summer topdressing of crops, and belongs to a special device for agricultural topdressing. Background technique [0002] Crops need to be topdressed in the summer. The fertilizer is usually sprayed around the roots of the crops by hand. Rainwater is needed to bring the fertilizer into the soil. However, this method has many drawbacks. First, because the fertilizer is composed of urea, It volatilizes quickly, is wasteful, and corrodes the skin when exposed to water, so the time for top dressing is limited. You can only wait until the dew of the crops evaporates at noon or afternoon before you can work. Farmers perform top dressing operations under the scorching sun. The working environment of farmers is harsh. It is prone to heatstroke, and this top dressing method requires a large amount of fertilizer. Moreover, because the fertilizer is floating on the so...

Problems solved by technology

[0002] Crops need to be topdressed in summer. Usually, manpower is used to sprinkle the fertilizer near the roots of the crops in trips, and rainwater is needed to bring the fertilizer into the soil. However, there are many defects in this method. First, because the fertilizer is composed of urea, It volatilizes quickly, wastes amazingly, and corrodes the skin after being exposed to water, so the time for top dressing is limited. You can only work after the dew on the crops evaporates at noon or afternoon. Farmers carry out top dressing operations under the scorching sun, and the working environment for farmers is harsh. It is prone to heatstroke, and this method of topdressing requires a large amount of fertilizer. Moreover, since the fertilizer is sprinkled on the soil above the roots of the crops, the state of the fertilizer is very unstable. In case of strong winds, it is easy to blow the loose fertilizer. In the furrows, if it does not rain for several days, it is difficult to bring the fertilizer into the soil in time to topdress the crops only by the dew at night. Even when it rains, the rainwater will wash the fertilizer floating on the soil into the furrows , in case of rapid rain or heavy rain, the fertilizer will be washed into the ditch by the rain before it can seep into the ground, resulting in insufficient topdressing of crops, and farmers need to replenish it again, resulting in a waste of fertilizer. Existing topdressers on the market , actually take out the lower fertilizer device on the planter and press the upper handle to turn it into a top dressing device. When in use, hold the handle and insert the duckbill of the topdresser into the soil near the roots of the crops, and the duckbill will apply fertilizer into the soil. Advantages It is best to apply fertilizer to the soil and topdress the fertilizer, and save fertilizer at the same time. However, this topdresser is only suitable for loose land that is turned over by the machine during spring plowing. After drying, it has been hardened, and farmers need to use a lot of effort to insert this top dressing device into the dry and hard land, which leads to a significant increase in the work intensity of farmers and slower work progress. Compared with the trade-off, most farmers have given up this kind of fertilizer. Fertilizer, for work efficiency, still use manual topdressing
