4results about How to "Prevent wilting" patented technology

This invention provides a storage rack for transporting agricultural products, relating to the field of agricultural product transportation. Its features include: a storage rack body, a loading / unloading mechanism, and a spraying mechanism; the loading / unloading mechanism and the spraying mechanism are respectively installed on the storage rack body; the loading / unloading mechanism includes multiple frames, several rollers, multiple conveyor belts, and several auxiliary shafts. The advantages of this invention are: by integrating an automatic spraying mechanism and an automatic loading / unloading mechanism, it effectively solves two major problems in agricultural product transportation. Its spraying system, through a reciprocating water collection tank and atomizing nozzles, can evenly and continuously moisturize fruits and vegetables, preventing wilting due to water loss, and avoiding the inaccuracies of manual watering; the loading / unloading mechanism, composed of conveyor belts and rollers, with an anti-slip design, can automatically transport goods from deep within the rack to the front, greatly reducing manual labor intensity and avoiding damage from bumps and squeezing caused by reaching out to retrieve goods.

The application relates to the field of new packaging materials, and provides a composite film for fresh-keeping of green leaf vegetables and a preparation method thereof, main raw materials of the composite film including a base material, citric acid, glacial acetic acid and nicotinamide; the base material is a mixture of chitosan and polyvinyl alcohol; the preparation method is that chitosan and polyvinyl alcohol are dissolved and mixed, then a nicotinamide solution is added, stirring and ultrasonic treatment are conducted to uniformly distribute the components, and finally a flow casting process is adopted to form a film. The composite film can effectively delay oxidation and corruption of green leaf vegetables, and significantly prolong the shelf life of the green leaf vegetables. The composite film has good mechanical properties and flexibility, and is suitable for various fresh-keeping applications. The preparation process is simple, easy for large-scale production, the material is environment-friendly and biodegradable, and the composite film has a wide application prospect.

The utility model relates to the technical field of anoectochilus formosanus planting, in particular to irrigation equipment for anoectochilus formosanus planting, which comprises a main body, two groups of planting racks are arranged in the main body, a plurality of groups of planting layers distributed at equal intervals are arranged in the planting racks, and a water tank is arranged at one end, far away from the planting racks, in the main body. A motor is arranged on the top of the water tank and located between the two planting frames, a threaded rod is rotationally connected to the position, located between the two planting frames, in the main body, a moving block is arranged on the outer side of the threaded rod and located between the two planting frames, and an electric lifting rod is fixedly connected to the position, located between the two planting frames, of the bottom of the moving block. One end, far away from the moving block, of the electric lifting rod is a driving end and is fixedly connected with a tray, atomization nozzles are fixedly connected to the two sides, close to the two sets of planting frames, of the tray, and compared with existing irrigation equipment for anoectochilus formosanus planting, the overall practicability of the irrigation equipment for anoectochilus formosanus planting can be improved through the design of the irrigation equipment for anoectochilus formosanus planting.

The application relates to the technical field of intelligent water-saving irrigation devices, and particularly provides an intelligent water-saving irrigation device and method for landscaping maintenance, which comprises two parallel water conveying pipes, a plurality of micro-spraying pipes are communicated between the two parallel water conveying pipes, the micro-spraying pipes are parallel to each other and perpendicular to the two parallel water conveying pipes, a plurality of micro-spraying holes are uniformly arranged on the periphery of the micro-spraying pipes, and an adjusting assembly is arranged, the adjusting assembly can automatically adjust the opening number of the micro-spraying holes according to the water pressure of the water conveying pipe, when the water pressure is reduced, the number of water outlet channels is reduced, the water pressure of the remaining spraying holes is increased, so that the attenuation of the water spraying distance is compensated, the irrigation blind area caused by the water pressure reduction in traditional irrigation is avoided, the landscaping plants are evenly watered, the local plants are prevented from wilting and withering due to water shortage, and the landscaping quality is ensured.
