The utility model relates to agricultural machinery technology field, and the utility model discloses a rotary cultivator blade shaft assembly, the utility model discloses in order to solve the rotary cutting speed of the rotary cultivator rotating tillage part in the prior art is slow, and the chopping capacity is poor, and in the humid environment, the soil of bending blade is often with mud ball when crushing, and the adaptability to soil is poor, and tractor needs multiple operations, and multiple operations lead to farmland compaction, and the rotary cultivator tool is seriously damaged and the like problem. The utility model discloses a blade shaft and a plurality of rotary tillage tool groups set on the blade shaft along the axial direction, and the rotary tillage tool group is composed of a blade disc and a plurality of rotary tillage blades arranged radially around the blade shaft, the rotary tillage blade includes three left rotary tillage blades and three right rotary tillage blades, and the rotary tillage blade is divided into three groups, each group of rotary tillage blade is composed of a left rotary tillage blade and a right rotary tillage blade, the blade disc is fixedly connected to the blade shaft, and the left rotary tillage blade and the right rotary tillage blade are both installed on the blade disc. The utility model is used for straw returning to field.

This invention relates to water pump technology to solve the problems of clogging and poor heat dissipation in water pumps during operation. Specifically, it is an anti-clogging water pump for farmland irrigation, comprising a pump body, an outlet pipe, and a suction pipe. The suction pipe is connected to one side of the outer wall of the pump body. This invention utilizes a pulverizing blade to enhance the crushing ability of impurities in the water flow. Impurities filtered by the filter screen frame are discharged from the filter box by a scraper gate, ensuring that the filtration effect of the filter screen frame does not weaken with increasing impurity levels. A cross-shaped rotating block on a rotating rod lifts a movable plate within the connecting frame, thereby lifting the filter screen frame and facilitating the removal of impurities from it by the scraper gate. The rotating rod also drives a reciprocating plate to stretch and compress a telescopic hose, allowing the hose to circulate water from the filter box to the water supply pipe for cooling the pump's internal components.

This invention relates to a multi-stage forward and reverse controllable dual-shaft rotary tiller, belonging to the field of rotary tiller seeder technology. It includes a frame with side plates on both sides, and two parallel rotary tiller shafts assembled between the two side plates. A drive mechanism is mounted on the frame, configured to drive the two rotary tiller shafts to rotate in opposite directions. The drive mechanism includes a transmission gearbox, a first gear arm, a second gear arm, a linkage adjustment structure, and a telescopic mechanism. The linkage adjustment structure is configured to control the unlocking or locking of the second gear arm. The telescopic mechanism is configured to, in the unlocked state, allow the second gear arm to swing around the main rotation axis as needed, adjusting the position of one of the rotary tiller shafts and adjusting the relative position of the two rotary tiller shafts to match the optimal tillage mode, significantly broadening the scope of application. It can also precisely control the overlap of the two cutting operations and the soil spreading path.
