Description

Technical Field

[0001] This utility model relates to the field of pesticide technology, and in particular to a pesticide dosage monitoring device for agricultural sprayers. Background Technology

[0002] With the popularization of smart agriculture and precision agriculture concepts, the traditional extensive spraying mode can no longer meet the requirements of modern agriculture for efficiency, safety and environmental protection. Accurate monitoring of pesticide dosage is the basis for achieving variable-rate application, which can avoid waste or insufficient pesticide solution, reduce production costs and reduce pesticide pollution to the environment. The shortage of rural labor and the increase in labor costs are forcing agricultural production to transform towards mechanization and intelligence. As the core equipment for plant protection operations, the intelligent upgrading of agricultural sprayers can reduce manual intervention, improve operational efficiency and alleviate labor pressure.

[0003] A search revealed Chinese Patent Publication No. CN216992061U, which discloses a liquid-dispensing agricultural sprayer, including a housing, a hydraulic pump, and a spray bar. The top of the inner surface of the housing is fixedly connected to the top of the hydraulic pump. A clamp is fixedly connected to the right side of the housing, and the inner surface of the clamp engages with the outer surface of the spray bar. This utility model relates to the field of agricultural technology. The liquid-dispensing agricultural sprayer divides the housing into two parts by a partition, with each part containing different pesticides to prevent mixing. The pesticide to be sprayed is selected by an adjusting valve. During the replacement process, the equipment is cleaned by connecting to an external water source through a cleaning pipe to prevent the influence of residual pesticides. This ensures that the equipment can carry different pesticides without affecting each other. The battery is connected to the power supply compartment by a detachable connecting block. The battery position is fixed by multiple sets of limiting holes, limiting grooves, and limiting rods, facilitating battery replacement and saving time. However, this utility model does not consider that if the discharge pipe cannot be sealed and closed when the connecting pipe is disassembled, it may lead to internal pesticide leakage, thereby causing environmental pollution. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an agricultural sprayer dosage monitoring device, which aims to improve the problem in the prior art where the discharge pipe cannot be sealed and closed when the connecting pipe is disassembled, which leads to internal pesticide leakage and environmental pollution.

[0021] As a further description of the above technical solution:

[0022] The pressure measuring assembly includes multiple pressure sensors, the bottom of which is fixedly connected to the bottom of the inner wall of the hollow box, and strain gauges are fixedly connected to the top of each pressure sensor.

[0023] The above technical solution involves installing a pressure sensor at the bottom of the inner wall of the hollow box, ensuring a stable connection with the structure. The strain gauge can sensitively capture pressure changes, providing a reliable basis for subsequent data analysis.

[0024] As a further description of the above technical solution:

[0049] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The pressure measuring component 306 includes multiple pressure sensors 3061. The bottom of the multiple pressure sensors 3061 is fixedly connected to the bottom of the inner wall of the hollow box 1.

[0051] Working principle: When the connecting ring 2031 needs to be disassembled, rotate the connecting ring 2031. The connecting ring 2031 will drive the fixing block 2032 to rotate, so that the fixing block 2032 rotates along the inner wall of the track 2041. When the fixing block 2032 rotates to the position of the track 2042, pull the connecting pipe 2033 to the right to disassemble the connecting ring 2031. During the rotation of the connecting ring 2031, since the fixing rod 2051 is already inserted into the insertion hole 2052, the fixing rod 2051 will rotate with the connecting ring 2031. Because the rotating valve 202 is fixedly connected to the fixing rod 2051, the rotating valve 202 will rotate accordingly, thereby closing the rotating valve 202. This achieves the simultaneous sealing and closure of the discharge pipe 201 during the disassembly process, preventing the leakage of internal pesticides and causing environmental pollution.

[0052] The pressure sensor 3061 at the bottom of the hollow box 1 can detect local pressure through the strain gauge 3062, and the ultrasonic probe 3072 installed at the top can emit ultrasonic waves to measure the liquid level. The baffle 305 will drop as the liquid level drops. Therefore, when the liquid level is below the warning line, the baffle 305 will block the infrared light emitted by the infrared lamp 304, reminding the staff to add pesticide in time. This enables the monitoring of multiple performance characteristics of the equipment, making it more convenient for personnel to use and improving the practicality of the equipment.
