Travelling field weeding shielding device

Abstract

The invention discloses a travelling field weeding shielding device. The device includes a weeding shielding device body, wherein the weeding shielding device body includes a mounting frame and shielding covers arranged on both sides of the mounting frame; a spraying device is arranged on the upper part of the mounting frame; a travelling device is arranged at the bottom; the spraying device includes an electric sprayer arranged on the mounting frame and spraying heads arranged at the bottom of the mounting frame; the shielding covers cover crops on both sides of a row space; the travelling device drives the weeding shielding device body to travel in the row space of the crops; the electric sprayer sprays weeding pesticide stored in the electric sprayer on weeds in the row space through the spraying heads, and the pesticide sprayed by the spraying device is prevented from being left and floated on the crops on both sides of the row space. The device disclosed by the invention has the beneficial effects that not only can the crops not be damaged when weeding is performed, but manpower is also saved; manual work is not needed to carry a pesticide box; the pesticide spraying height and spraying range can be controlled; the workload of manual spraying is reduced; the efficiency of pesticide spraying is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a walking type farmland weeding and shielding device. Background technique [0002] Agriculture is the basic industry of the country. Agricultural products provide guarantee for people's life and production. When crops are planted, weeds often grow in the land. In order to ensure that the nutrients of crops are not divided by weeds, people often need to remove weeds. At present , Weeding tools, as tools that play an important role in agricultural production, have the most direct impact on the yield of crops. [0003] There are generally the following ways to pull out weeds in the field: one is to directly pull out the weeds by hand, which not only requires a lot of labor, damages the hands, but also has low work efficiency; It is difficult to eradicate and the weeding effect is not obvious. The third is to use a weeding machine to weed. Although the weeding speed ...

Problems solved by technology

[0003] There are generally the following ways to pull out weeds in the field: one is to directly pull out the weeds by hand, which not only requires a lot of labor, damages the hands, but also has low work efficiency; It is difficult to eradicate and the weeding effect is not obvious. The third is to use a weeding machine to weed. Although the weeding speed is fast, the roots of the weeds cannot be removed. The common method of weeding in farmland now is to spray pesticides or herbicides on a large area. Although weeds are eliminated, it still has the following disadvantages in actual use:

[0004] 1. This method must accurately grasp the concentration of pesticides. If the concentration is not enough, the weeding effect will not be obvious. If the concentration is too high, it will kill the crops together, and the pesticide is not directly sprayed on the roots of the weeds, which greatly reduces the weeding effect;

[0005] 2. The traditional spraying of pesticides or herbicides requires farmers to carry the cartridges on their backs and walk in the farmland. It is relatively heavy and has a limited capacity for carrying pesticides. This kind of pesticide spraying device not only needs to be carried by manpower, but also manually It is necessary to manually swing the nozzle, and the long-term operation can easily cause people's fatigue. The labor load is large, time-consuming and labor-intensive, and the work efficiency is reduced. The spraying range is limited and the spraying effect is average. The water mist sprayed by pesticides contacts people's mouths and noses, and at the same time, the herbicide dripped from the cartridges flows on the farmers' backs, causing harm to the skin and damaging people's health;

[0006] 3. Large-scale farms use drones to spray herbicides, which is costly, but it is not suitable for self-employed farmland production. There is an urgent need for a small-sized, low-cost, and easy-to-operate small mechanized herbicide spraying device to provide services for self-employed farmland;

[0007] 4. Existing pesticide spraying machines generally need to lay pesticide pipelines and set up many pesticide nozzles scatteredly to spray pesticides, which requires a lot of financial resources, and for crops with different plant heights, it is difficult to adjust the pipelines at any time, resulting in poor spraying effect

[0011] However, when the distance between crop plants is too small or too large, spraying pesticides will cause inconvenience. On the one hand, the distance between crop plants is too large, and some positions cannot be sprayed with pesticides. Grass, on the other hand, if the distance between the crop plants is too small, the pesticide will be sprayed on the crops, causing damage to the crops
