The invention relates to a multifunctional ecological purification system for large-scale circulation breeding water, which is used for exchanging water in a pond and purifying the breeding wastewater in the pond. The purification system comprises an efficient precipitation and filtration region, an ecological breeding purification region, an artificial wetland purification region, a water collecting pond and an automatic water quality monitoring and regulating device, wherein the efficient precipitation and filtration region, the ecological breeding purification region and the artificial wetland purification region are used for purifying a water body, and the automatic water quality monitoring and regulating device is used for monitoring the quality of the water body in the purification system and controlling operation of the purification system. Compared with the prior art, the system can be used for automatically monitoring the water quality in the system, so that water in the pond can satisfy the requirements of aquaculture water after being subjected to circulation treatment of the purification system. Meanwhile, aquatic animals and plants and bottom mud generated in the purification system can be recycled. The system provided by the invention can be applied to purifying large-scale aquaculture wastewater and has good economic and environmental benefits.

The invention discloses an agricultural fruit picking buffer device. The device comprises a feeding port formed in a lifting support, a hose channel communicating with a fruit collecting box, a buffermechanism and a feeding mechanism, the lifting support, the buffer mechanism and the fruit collecting box are all installed on a base, and the end, away from the fruit collecting box, of the hose channel communicates with the feeding port. The buffer mechanism is located under the feeding port, and the feeding mechanism is movably connected with the hose channel. According to the agricultural fruit picking buffer device, through cooperation of the feeding port formed in the lifting support, the hose channel communicating with the fruit collecting box, the buffer mechanism and the feeding mechanism, fruits can be buffered after being thrown down, and the fruits cannot be broken due to falling. The feeding mechanism is automatically started for feeding, manual control is not needed, convenience is achieved, and the problems that according to most existing fruit pickers, after fruits are picked down, the fruit pickers are taken back, the fruits are taken down, the manner is too troublesome, the fruits are directly thrown down, and the fruits are likely to be broken are solved.
