The invention relates to the technical field of ecological restoration, in particular to a degraded grassland ecological restoration method based on an unmanned aerial vehicle, which comprises the following steps: (1) grassland information acquisition; (2) a degradation evaluation step; (3) a terrain analysis step; (4) a sowing scheme generation step; (5) variable sowing execution; (6) repairing and monitoring; according to the method, the high-precision degradation degree and terrain information are obtained through the multispectral remote sensing and laser radar technology, precise control over the grass seed ratio and the sowing density is achieved in combination with the variable sowing decision model, and compared with a traditional unified sowing mode, the grass seed utilization rate is increased, and the restoration success rate is increased.

The utility model discloses a liquid mixing device, relates to the technical field of medicine processing devices, and solves the problems that the mixing effect is poor, the activity of added components is damaged due to mechanical stirring and the like. Comprising a mixing pipeline, the mixing pipeline conveys at least two kinds of liquid, the mixing pipeline is connected with a mixer, the mixer comprises an outer pipe and a central shaft, the central shaft is arranged in the outer pipe, and the outer pipe is connected with the mixing pipeline to form communication; a plurality of stirring and mixing blocks are fixedly arranged on the central shaft in the axial direction of the central shaft, the stirring and mixing blocks protrude outwards in the radial direction of the central shaft, a preset distance is formed between every two adjacent stirring and mixing blocks, and a preset included angle is formed in the mounting direction of every two adjacent stirring and mixing blocks. By means of the uniform mixer, especially the stirring and mixing blocks which are arranged in a staggered mode, a strong turbulent flow effect can be generated when liquid flows through the uniform mixer, the liquid can be promoted to form complex vortexes and folds, collision and diffusion among liquid molecules are greatly improved, and therefore the mixing efficiency is improved.

This invention discloses a lucky bag binding machine, including a bean curd skin feeding frame, a main frame fixedly installed on one side of the bean curd skin feeding frame, a bean curd skin feeding conveying mechanism fixedly installed at one end of the bean curd skin feeding frame, a bean curd skin cutting mechanism fixedly installed on one side of the top of the bean curd skin feeding frame, dry ladle feeding mechanisms fixedly installed at both ends of one side of the inner wall of the main frame, two binding mechanisms fixedly installed on the main frame above the dry ladle feeding mechanisms, a filling conveying mechanism fixedly installed on one side of the top of the main frame, and a finished product conveying mechanism fixedly installed inside the main frame. This invention adopts automated assembly line operation throughout the entire production process, realizing integrated automatic operation from raw material conveying, food processing, molding to finished product discharge, without the need for a large number of people to be on duty throughout the process. Compared with the traditional manual production mode, it completely avoids the problems of low efficiency, high labor costs, and raw material waste caused by human error in manual operation.

The invention belongs to the technical field of flame-retardant materials, and particularly relates to an aluminum hypophosphite flame retardant with a spheroidic pine-cone-shaped laminated structure and a preparation method and application thereof.The flame retardant is an inorganic phosphorus halogen-free flame retardant, the microstructure of the aluminum hypophosphite flame retardant is of the spheroidic pine-cone-shaped laminated structure, a single particle is formed by stacking a plurality of sheet layers in a staggered mode, and the sheet layers are stacked in a staggered mode. Forming a regular sphere-like outer contour; the thermal decomposition temperature of the aluminum hypophosphite flame retardant is higher than 330 DEG C, the particle size distribution meets the conditions that the particle size D10 ranges from 8 micrometers to 15 micrometers, the particle size D50 ranges from 25 micrometers to 40 micrometers, the particle size D90 ranges from 60 micrometers to 80 micrometers, the particle size D97 ranges from 80 micrometers to 100 micrometers, and the specific surface area ranges from 1.2 m / g to 3.5 m / g. According to the present invention, the continuous stacking preparation process of primary crystallization in the crystallization kettle, dissolution in the dissolution kettle and crystal growth in the precipitation kettle is adopted, the parameters in the preparation process are controllable, no auxiliary agent is added, the method is suitable for industrial mass production, and the flame retardant can be applied to engineering plastics, and can achieve efficient flame retardation and good mechanical properties.
