A system includes a hollow shaft, a drum, an absolute encoder, a driving mechanism, a conveyor belt, a photoelectric sensor, and a controller. A structural optimization design method of the drum is provided on the basis of theoretical calculation of a seeding track of the drum-type seed-metering device, a theoretical model of a conveying position of a tray and a seed-metering angle is built with the aim of continuously sowing grains to the center of each hole, the conveying position of the tray and a rotating position of suction holes on the drum are monitored in real time on a seedling raising line, and a difference value between the actual position of the suction holes and the theoretical seed-metering angle and a change rate of the difference value are calculated and serve as input parameters to design a fuzzy controller of the rotation speed of the drum.

The present invention disclosesand a method for improving fermentation quality of a low-salt fish sauce by, and relates to the application field of food microbiology technology. Thestrains have been deposited in China General Microbiological Culture Collection Center (CGMCC) under CGMCC NO. 17057, CGMCC NO. 17058, CGMCC NO. 17059, and CGMCC NO. 17060. The production cycle of fermented fish sauce using thestrains is greatly shortened, and the fermentation temperature is reduced. The fish sauce obtained by this method is transparent brown red, and has the unique aroma of aquatic products without impurities such as suspension or flocculent. The finished fish sauce has low salt content and high amino acid nitrogen content (according to the Chinese fish sauce industry standard, the fish sauce is classified as first-grade fish sauce). The contents of total volatile basic nitrogen and histamine are lower than the national standard.

A device for measuring the internal temperature of heap fermentation includes an infrared thermal imaging camera, a distance detection camera, and a controller. The infrared thermal imaging camera obtains a temperature distribution image of a surface of a fermentation heap. The distance detection camera obtains a distance between the surface of the fermentation heap and the distance detection camera. The controller matches the temperature distribution image of the surface of the fermentation heap with the distance between the surface of the fermentation heap and the distance detection camera, performs semantic segmentation on the image after matching is completed, extracts a three-dimensional (3D) contour temperature map of the surface of the fermentation heap, corrects a surface temperature of the fermentation heap, and predicts an estimated internal temperature of the fermentation heap, such that the internal temperature of the fermentation heap is effectively and accurately predicted.

A linear surgical stapler includes an upper staple cartridge receiving half-section, a lower staple cartridge receiving half-section and a staple cartridge assembly. The staple cartridge assembly includes a cutting groove in which a reciprocating movement cutter is mounted. The cutter includes a bottom surface and a knife blade located at a far end of the cutter. The staple cartridge assembly includes a restricting member mounted therein and an elastic stopper. The elastic stopper abuts against the restricting member when the staple cartridge assembly is in an initial state. The restricting member breaks away from the staple cartridge assembly when the staple cartridge assembly is in a firing complete state, thereby preventing the cutter from sliding towards the far end of the staple cartridge. As a result, misfiring throughout the whole operation of the linear surgical stapler is prevented.

A linear cutting stapler includes an upper jaw and a lower jaw capable of closing or opening relative to each other. A staple cartridge is disposed at a distal end of the lower jaw. The lower jaw is U-shaped, and has a staple driving rod and a blade driving rod slidably disposed therein. The linear cutting stapler further includes a safety mechanism which includes an engagement member. A notch fitting the engagement member is disposed on a bottom surface of the staple driving rod. The safety mechanism further includes a floating block which is displaceable in the lower jaw in an up-down direction perpendicular to the length direction of the lower jaw. When the floating block is pressed against the staple cartridge or an anvil, a top end of the engagement member is driven to displace in the up-down direction, thus the engagement member is separated from the notch.

The present invention provides an instrument for anorectal surgery, comprising a hollow main body, a suture junction disposed at a rear end of the main body and an inserting guider disposed at a front end of the main body. At an operating position, all or part of mucosa and tissues can get through the main body. At least one opening is made in the wall of the main body, and all or part of the mucosa and tissues can get into a hollow interior of the main body through the opening. Because of the openings on the wall of the main body, the present invention can be operated to perform the anorectal surgery of local and non-annular cutting, which facilitates a quick surgical operation, further allays the pain of the patients, and a better operation effect is obtained.
