It includes a base plate, a square box fixedly connected to the top of the base plate, a cylinder fixedly connected to the right side of the inner wall of the square box, a slider fixedly connected to the driving end of the cylinder, a limit block fixedly connected to the top of the slider, two limit plates fixedly connected to the inner wall of the base plate, and a connecting rod slidably connected to the adjacent side of each of the two limit plates. A fixing plate is fixedly connected to the outer wall of the connecting rod. This utility model facilitates the integration of manual operation and mechanization, reducing labor intensity. It can also be efficiently integrated with transplanters and sprinkler irrigation equipment, reducing labor costs. Combined with temperature and humidity sensors, it can achieve automated environmental control, reducing energy consumption and pest and disease risks, providing strong support for the standardized and large-scale seedling cultivation of Chinese herbal medicines.

The present invention relates to the field of high-pressure sealing technology, and in particular to a sealing ring blank pressing tool and a sealing ring pressing method. The sealing ring blank pressing tool comprises an outer ring sleeve and an inner ring sleeve, wherein the outer ring sleeve is sleeved outside the inner ring sleeve, the bottom of the outer ring sleeve has a first annular cutter, the bottom of the inner ring sleeve has a second annular cutter, the bottom of the outer ring sleeve has a blank accommodating space, and the blank accommodating space is located on the inner side of the first annular cutter; the parts are pressed by a non-overlapping annular feeding method, which solves the problem of fracture and surface bubbling of the pressed parts under the action of high pressure. By adopting the above-mentioned structural form, the sizes of the first annular cutter and the second annular cutter can be determined according to the appropriate blank blanking, and the thickness of the flash of the formed parts is controlled within a suitable range, which is conducive to the removal of the flash.

The utility model discloses a crystal growth continuous feeding device which comprises an operation box and a reaction container, the bottom wall of the reaction container protrudes upwards to form an inner baffle, the inner baffle enables a crystallization area and a liquid supplementing area to be formed in the reaction container, the top of the inner baffle is fixedly connected with a filter screen, and the top end of the filter screen is lower than the top end of the reaction container. A heater is arranged outside the crystallization area; a liquid conveying pipe is connected to the bottom side of the liquid box, the free end of the liquid conveying pipe is arranged in the liquid supplementing area, and the bottom end of the crystal block is arranged in the crystallization area. According to the utility model, a crystal growth solution is injected into the liquid supplementing area, and along with the rising of the liquid level in the liquid supplementing area, when the liquid level exceeds the inner baffle plate, the solution flows into the crystallization area, liquid supplementing is carried out on the crystallization area, and bubbles are filtered and intercepted by the filter screen, so that the crystal growth solution supplemented in the crystallization area does not generate bubbles; crystal growth malformation is avoided, holes or cracks are formed, and it is guaranteed that the whole device can stably output high-quality crystals.

The application belongs to the technical field of sporogon culture, and particularly relates to a culture method of sporogon of Brychus based on a liquid culture medium, which comprises the following steps: S1, preparing a Brychus sample with mature sporogon; S2, preparing a spore suspension, taking a mature sporangium of the Brychus and taking out spores, and dispersing the spores into distilled water to prepare a spore suspension; and S3, inoculation, inoculating the spore suspension into a culture bottle containing a liquid culture medium, and then culturing the culture bottle after being covered. The application customizes a special liquid culture medium formula according to the physiological characteristics and growth requirements of the sporogon of the Brychus, and matches highly adaptive culture environment parameters, and the two synergistically ensure the smooth culture of the sporogon of the Brychus from the two dimensions of nutrient supply and environment adaptation.
