The utility model provides an automatic root scraping device for vegetable floating tray seedling culture. The vegetable floating tray seedling automatic root scraping device comprises a shell, a rectangular opening is formed in the top of the shell, and a plurality of supporting plates used for supporting vegetable floating trays are fixedly installed on the inner wall of the top of the shell; the two supporting blocks are both fixedly mounted at the top of the shell; the two fixing mechanisms are arranged on the two supporting blocks respectively and used for fixing vegetable floating trays; and the root scraping mechanism is assembled on the shell and is used for scraping root systems. The automatic root scraping device for vegetable floating tray seedling culture solves the technical problems that existing root scraping treatment for vegetable floating tray seedling culture is time-consuming and labor-consuming, working efficiency is low, and removed root systems are inconvenient to collect.

The utility model relates to the technical field of municipal road construction multi-bin pipe gallery structure construction, in particular to a movable type splicing concrete discharging device which comprises a discharging groove, the discharging groove comprises an upper groove body and a lower groove body, and the discharging groove is formed by assembling four plate materials through a mortise and tenon joint structure. The bottom surface of the guide rail adopts an inner concave surface embedded with a surface layer reinforcing steel bar, the guide rail is of a hollow thin-wall structure, the guide wheel is mounted at the bottom of the supporting leg, threaded holes are formed in the supporting leg and horizontally penetrate through the supporting leg, and a screw rod penetrates through the left threaded hole and the right threaded hole which correspond to each other. And the supporting legs are welded on the bottom surface of the lower tank body. The discharging device can effectively solve the construction cold seam formed due to the fact that the initial setting time of concrete between a wall body and a top plate is exceeded when the concrete is poured, and the structural integrity is guaranteed.

The invention relates to the technical field of stirring machines, in particular to a multifunctional stirring machine for hypha cultivation, which comprises a stirring tank, a carrying table is arranged at the lower end of the stirring tank, a stirring mechanism is arranged between the carrying table and the stirring tank, a feed port and a discharge port are arranged on the stirring tank, a water supply mechanism is arranged on the carrying table, and a water outlet is arranged on the water supply mechanism. A water outlet pipe is arranged at the output end of the water supply mechanism, a sealing structure is arranged on the feeding port, and a heating wire is arranged on the carrying table. The sealing structure comprises a sealing cover, the sealing cover covers the feeding port, a connecting arm is rotationally arranged on the feeding port, and a heating wire is arranged on the carrying table to heat the stirring tank, so that vinasse in the stirring tank is stirred, volatile substances such as alcohols and aldehydes are promoted to volatilize, acid substances in the vinasse are removed, and the vinasse can be uniformly stirred. And the stirring mechanism is used for stirring, so that the vinasse is uniformly heated, and the vinasse is convenient to volatilize and react.

The present application relates to the field of aquaculture breeding technology, and discloses an indoor cement pool artificial breeding method for east wind snail, which comprises the following steps: storing east wind snail egg sacs after disinfecting water body by ultraviolet rays, removing infected egg sacs, and performing specific water flow replacement 24 hours before hatching; feeding the larvae with a nutrient agent containing clostridium aceticum protein and agaricus blazei polysaccharide every day after hatching, feeding the larvae with monosomic algae such as chrysomonad, tetraselmis, chlorella, etc. in the early stage, and feeding the larvae with shelled algae in the middle stage until the larvae are attached and metamorphosed; keeping the breeding pool continuously aerated and controlling parameters such as dissolved oxygen, salinity, temperature and pH value of the water body during the breeding period, and finally collecting the snail seedlings to end the breeding. The indoor cement pool artificial breeding method for east wind snail provided by the present application is suitable for one or more of fasciolaria fasciolaris and mud east wind snail, and can effectively improve the success rate and seedling quality of indoor cement pool breeding of east wind snail.

The utility model relates to a movable type assembled concrete discharging device which comprises two guide rails arranged in parallel and a discharging groove arranged between the two guide rails in a sliding mode, clamping grooves are formed in the bottom faces of the guide rails, the guide rails are connected to surface layer steel bars in a clamped mode through the clamping grooves, guide rail grooves are formed in the surfaces of the guide rails, and a discharging opening is formed in the center of a bottom plate of the discharging groove. Two movable plates which can move in the opposite directions or in the opposite directions and adjust the size of the discharging opening are arranged on the bottom plate above the discharging opening in a sliding mode, supporting legs are arranged at the four corners, corresponding to the discharging opening, of the bottom plate respectively, and guide wheels located in the guide rail grooves are rotationally installed at the ends of the supporting legs. The discharging speed of the discharging opening can be adjusted, the situation that concrete is scattered is reduced, labor and material cost is saved, and the purposes that the structure is reliable and attractive can be achieved.
