Agricultural spraying machine with water level alarm function

Abstract

The invention belongs to the field of an agricultural technology, and discloses an agricultural spraying machine with a water level alarm function. The agricultural spraying machine with the water level alarm function comprises a spraying assembly and a protecting assembly arranged in the spraying assembly, wherein the protecting assembly comprises a communicating pipe, electric contact pieces, afloating block, an insulating bush and a sliding rod; a sliding rod is fixedly connected into the communicating pipe; the floating block is arranged on the outer side of the sliding rod in a sleevingway; the electric contact pieces are arranged on the top part of the floating block and the inner side of the sliding rod; the electric contact piece located on the inner side of the sliding rod is electrically connected with an external power supply; the electric contact piece located on the floating block is electrically connected with the spraying assembly; when a water level in the spraying assembly is higher, a floating force of water drives the floating block to move upwards, so that the two electric contact pieces fit to form an access, and the spraying assembly works; and when the water level is lowered to a certain position, the two electric contact pieces are separated to form an open circuit, and the spraying assembly is powered off so as to stop working, so that the occurrenceof the problem that when the water level in the spraying assembly is lower, the spraying assembly is powered on to work so as to cause idling and influence the service life of internal elements is avoided.

Description

technical field [0001] The invention belongs to the technical field of agriculture, in particular to an agricultural sprayer capable of alarming water levels. Background technique [0002] A sprayer is a machine that disperses a liquid into a mist. It is a kind of machinery. It is divided into agricultural, medical and other uses (such as industrial use). The agricultural machinery is classified as agricultural machinery and plant protection machinery; it is generally called a human-driven sprayer. The power (engine, motor) drives the sprayer; the sprayer is divided into hydraulic, pneumatic and centrifugal sprayers according to the working principle. [0003] The sprayer is generally equipped with a water tank. The clean water inside the water tank is pumped out by the water pump and then sprayed out through the nozzle with small holes to atomize the clean water. The clear water is pumped out, and it will cause the water pump to run dry, which seriously affects the service...

AI Technical Summary

Problems solved by technology

[0004] The invention provides an agricultural sprayer with water level alarm, aiming at solving the problem that the fog machine is generally equipped with a water tank, and the clear water inside the water tank is pumped out through the water pump and then sprayed out through the nozzle with small holes to atomize the clear water. When the internal clean water level is low, if the clean water is not added in time, not only the clean water cannot be pumped out, but also the water pump will run dry, seriously affecting the service life of the pump
