Description

Technical Field

[0001] The utility model relates to the technical field of pesticide dilution, in particular to a cornfield herbicide concentrate dilution device. Background Art

[0002] Usually, herbicides are made into concentrates for the convenience of transportation, storage and use. The volume of herbicides can be greatly reduced by making them into concentrates, which makes transportation more convenient and economical. During long-distance transportation, concentrates not only take up less space, but also weigh less, thus reducing transportation costs; concentrates usually have a longer shelf life and can be stably stored under different environmental conditions, thus ensuring the quality and effect of the herbicide; before use, the concentrate needs to be diluted, and the concentrated solution weighed and diluted according to the spraying area.

The volatile gas of the drug will cause harm to the health of the operator. In addition, the weighing process increases the labor intensity of the operator and reduces the working efficiency of the equipment. Utility Model Content
