[0002] Agricultural machinery vehicles are motor vehicles used for agricultural production, rural transportation and other agricultural-related operations. They are generally suitable for farmland operations, agricultural product transportation or rural infrastructure. Among them, curved drive reciprocating agricultural machinery vehicles use a special curved drive mechanism and work in a reciprocating motion. However, in order to improve the driver's working environment and allow the driver to adapt for a long time, the existing curved drive reciprocating agricultural machinery vehicles are equipped with air conditioners when in use. The air conditioner is composed of an evaporator, a condenser, an air-conditioning compressor, a throttling device and other parts.

[0003] In the existing technology, the existing curved drive reciprocating agricultural machinery air-conditioning compressor can absorb and compress the low-temperature and low-pressure gaseous refrigerant from the evaporator to increase its temperature and pressure during actual use, but it is not equipped with an emergency handling mechanism, that is, the electromagnetic clutch of the air-conditioning compressor is suddenly damaged during use, and the air-conditioning compressor needs to continue working for a period of time. At this time, if the air compressor is not equipped with an emergency handling mechanism, the air-conditioning compressor will stop working immediately when the electromagnetic clutch is damaged. At this time, the temperature of the agricultural machinery cab where the driver is located cannot be adjusted, which leads to a decrease in the comfort of the driver's working environment, which not only reduces the use effect of the curved drive reciprocating agricultural machinery air-conditioning compressor, but also reduces the use efficiency of the curved drive reciprocating agricultural machinery air-conditioning compressor.

At this time, if the air-conditioning compressor is not equipped with an emergency handling mechanism, the air-conditioning compressor will stop working immediately when the electromagnetic clutch is damaged. At this time, the temperature of the agricultural machinery vehicle cab where the driver is located cannot be adjusted, which leads to a decrease in the comfort of the driver's working environment, which not only reduces the use effect of the curved surface drive reciprocating agricultural machinery vehicle air-conditioning compressor, but also reduces the use efficiency of the curved surface drive reciprocating agricultural machinery vehicle air-conditioning compressor.

At this time, the threaded end of the rotating hexagonal bolt 216 will move out from the inside of the second threaded groove 214, and then the hexagonal bolt 216 will be moved out from the inside of the T-shaped hole 215. Then, use the tool to move the U-shaped block 209. At this time, the moving U-shaped block 209 will drive the limit block 206 to move.The movable limit block 206 will also drive the limit block 206 to move under the cooperation of the two installation blocks 210, the round rod 211 and the rectangular groove 203. At the same time, the round hole 207 will also change with the change of the position of the limit block 206, and the spring 212 will also be stretched. When the interior of the round hole 207 is connected to the interior of the first thread groove 213, the end of the L-shaped block 205 away from the spring 212 is just inside the slot 204. Then the hexagonal bolt 216 is passed through the interior of the round hole 207 until the threaded end of the hexagonal bolt 216 is connected to the interior of the first thread groove 213. When the hexagonal bolt 216 completes the installation operation, the force applied to the U-shaped block 209 is directly stopped. At this time, under the cooperation of the round hole 207, the hexagonal bolt 216, the first thread groove 213, the rectangular groove 203 and the limit block 206, the spring 212 can be prevented from driving the L-shaped block 205 to reset and move, and the air-conditioning compressor can be used again.
