The utility model discloses a storage device for rape seed breeding, and relates to the technical field of rape seed storage devices.The storage device comprises a base, two supporting seats are symmetrically installed on the top face of the base, the two supporting seats are jointly and rotationally connected with a storage barrel, a rotating mechanism is arranged on the top face of the base, and the rotating mechanism drives the storage barrel to rotate; when the seed stirring device is used, the driving mechanism drives the material stirring shaft to rotate, then seeds are stirred through the material guide plate, static accumulation of the seeds is avoided, the porosity among the seeds can be increased, cold air is discharged through micropores of the material guide plate in cooperation with the cold air conveying mechanism, and therefore the seed stirring device is used for stirring the seeds. And cold air can quickly take away heat emitted by the seeds, so that mildew caused by accumulation is avoided.

This invention relates to the field of N-(2,4-dinitrophenyl)-4-nitrobenzamide preparation technology, specifically to a green method for preparing nitramide compounds. The method involves adding a catalyst and dispersant to a reactor and mixing them uniformly. Then, a first and a second stream of materials are simultaneously added dropwise to the reactor for reaction. The temperature within the system is controlled during the dropwise addition. After the dropwise addition is complete, the temperature is increased to continue the reaction. After the reaction is completed, N-(2,4-dinitrophenyl)-4-nitrobenzamide is obtained through post-treatment. The first stream is a dispersion containing 4-nitro-N-phenylbenzamide, and the second stream is a nitrating agent consisting of a uniform mixture of N₂O₅ and nitric acid. This preparation method features high product conversion rate, a mild reaction process, safe and controllable production process, effectively reduces the amount of residual intermediates, and minimizes pollution.

This utility model relates to the field of rubber extruder technology, specifically a funnel-shaped rubber extrusion device. The device includes a barrel for connecting to the rubber extruder hopper, a discharge head detachably connected to the end of the barrel, and a plunger head slidably connected inside the barrel. A mandrel is disposed inside the discharge head, and a funnel-shaped extrusion orifice is formed at the rear end of the mandrel. A conical head that mates with the inclined surface of the extrusion orifice is fixedly connected to the front end of the plunger head. The funnel-shaped mandrel design of this device improves the utilization rate of rubber in a single extrusion, reduces the amount of rubber remaining in the die head, and minimizes material loss and energy consumption caused by secondary extrusion. The device also features a high sealing strength between the discharge head and the barrel, preventing rubber residue from remaining in the gap between them. Furthermore, the device allows for the replacement of the central mandrel, enabling the processing of rubber of corresponding sizes according to different product dimensions.
