Description

Technical Field

[0001] The utility model relates to the technical field of plant protection, in particular to a self-propelled plant protection spraying device. Background Art

[0002] Plant protection is directly related to the production quality and quantity of food and agricultural products. By controlling pests and weeds, we can ensure the healthy growth of crops, improve yield and quality, and thus ensure food security and the stable development of the agricultural economy. Plant protection is not only related to the ecosystem of farmland, but also affects the wider ecological environment. Through reasonable pest and disease control measures, we can reduce the negative impact on the environment and maintain ecological balance and local biodiversity.

[0003] Plant protection sprayers are equipment used to spray pesticides or other treatment agents on farmland and horticultural crops. Their design and use are crucial to effectively control pests and diseases, weeds, and ensure crop health and yield. Sprayers can not only improve the efficiency of agricultural production and crop protection effects, but also effectively reduce the impact on the environment, meeting the requirements of sustainable development of modern agriculture.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Most common plant protection spraying devices are handheld or backpack spraying devices, which are only suitable for spraying plants of small or medium areas. When a large area needs to be sprayed, the labor of the staff will be significantly increased and the spraying efficiency will also be reduced; 2. Common plant protection spraying devices spray at a single fixed angle. When the plant area is too large, the spraying time will also increase, and the spraying range will not change, which will reduce the working efficiency of the spraying device. Utility Model Content
