This utility model relates to the field of engineering machinery and equipment technology, and provides a jet grouting pile device, which solves the technical problem that traditional large-diameter pile construction often requires large-tonnage, high-torque jet grouting machines, resulting in high energy consumption. The jet grouting pile device includes a drilling tool, which includes a drill bit assembly and at least one set of agitator blade units fixed to the outer periphery of the drill bit assembly and distributed in a ring-shaped interval. The drilling tool is a rotary jet grouting drill, and the drill bit assembly is provided with lateral nozzles; the agitator blade units include agitator blades and breaking teeth distributed on the agitator blades, and the injection channel of the nozzle is not higher than the breaking teeth.

This invention discloses a design method and device for a wheat field weeding actuator based on an operational power consumption model. The weeding actuator includes a rotary blade and a roller, with multiple rotary blades connected to the roller. The initial position is taken as the tip of the rotary blade contacting the soil. The entire weeding process is divided into four working conditions: contacting the soil, cutting the soil, chopping the grass, and lifting the soil. The rotary blade weeding actuator then employs a power consumption model during operation: W = ∑ i 1(W1+W2+W3+W4); The wheat field weeding device mainly consists of a rotary blade, rollers, a drive motor, a controller, and auxiliary mechanisms. The actuator of this invention uses a weeding wheel structure. By analyzing the robot-soil-weed interaction during wheat field weeding, a power consumption model of the rotary blade weeding robot actuator is constructed, and the structural parameters with the lowest power consumption during operation are determined. This not only results in a wide working area, low operating resistance, and high weeding efficiency, but also effectively solves the problem of high seedling damage rate when weeding crops with small row spacing.

The application discloses a novel plugging and flow guiding robot applied to pipeline emergency repair operation, relates to the technical field of oil and gas pipeline emergency repair, and comprises a sealing flow guiding device capable of guiding and dredging the medium conveyed in a pipeline, and two traction support units symmetrically arranged on the two sides of the sealing flow guiding device. Each traction support unit comprises a robot power device and a support part. Universal couplings for realizing bend self-adaption are arranged between the robot power devices and the support parts on the same side and between the support parts and the corresponding sides of the sealing flow guiding device. The main function of the device is to implement dynamic plugging at the pipeline rupture position. After a rupture crack is found, the robot travels to the position, the air bag of the plugging system is inflated through an inflation pump, the sealing air bag is inflated to tightly contact the pipeline, a sealing area is formed at the rupture position, and the liquid in the pipeline flows away through the small bypass flow guiding pipe.

The present application relates to a kind of soil remediation equipment, comprising: frame;Plough is arranged in front of frame;Rotary shaft is arranged in rear of frame and is located in the rear side of plough, rotary shaft is installed with plowshare;Spraying pipeline is arranged on rotary shaft, spraying pipeline is provided with at least one nozzle, nozzle is close to plowshare to be set to spray pesticide to soil interior when plowshare operation.Such, by setting plough in front of frame to pre-break soil structure, reduce subsequent plowshare resistance, plowshare installed on rotary shaft in rear of frame is rotated at low speed to reduce soil aggregate structure damage, while spraying pipeline is arranged on rotary shaft close to plowshare to spray pesticide to soil interior, form " plough pre-break resistance-low speed plowshare soil turning-close to plowshare spray medicine " synergic structure, effectively realize the sufficient turning of about 50cm deep soil, promote the uniform mixing of pesticide and deep and shallow soil, inhibit the secondary pollution caused by dust from source.
