Portable semiautomatic screw screener

Abstract

The invention discloses a portable semiautomatic screw screener, comprising a body component and a screw suction component. The body component includes a housing, a base, a seal cover, a main handle,an auxiliary handle, a transmission motor, a cutting saw, a PCB (printed circuit board) and a lithium battery; the base is arranged on the lower surface of the housing and is fixedly connected to thehousing; a transmission motor is electrically connected with the lithium battery; the transmission motor drives the cutting saw to rotate; the cutting saw is aligned to weeds for clearing; after the weeds are cleared, the transmission motor and the lithium battery are disconnected; the screw suction motor is electrically connected with the lithium battery; a screw suction head is used to suck in screws; a screw suction tube is used to feed the screws into a strainer; separating and filtering are performed via centrifugal force generated by wind according to different specific gravities of objects, and therefore, the key difficulty in separating screws from other objects is overcome and screw collection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of oncomelania investigation mechanization, in particular to a portable semi-automatic onnail investigation machine. Background technique [0002] Oncomelania is a mollusk, divided into male and female, amphibious on land and water, consisting of shell and mollusk. The front part of the mollusk is the head, neck, feet and mantle, and the rear part is the viscera, and the surface has longitudinal ribs. "Snail with rib shell", the shell is about 10 mm long and 4 mm wide, and it lives in lakes and swamps or water network areas. Those with smooth shell surface are "light shell snail", which are slightly smaller than the snail with rib shell, and the length and width are 6 mm respectively. and three millimeters, more common in hilly areas, snails are the only intermediate host of Schistosoma japonicum. [0003] Most of the current methods of oncomelania investigations are traditional manual inspection of snails,...

Problems solved by technology

[0004] The purpose of the present invention is to provide a portable semi-automatic snail inspecting machine to solve the problem that most of the current oncomelania investigation methods proposed in the above-mentioned background technology all adopt the traditional manual inspection of snails, and most young adults in schistosomiasis endemic areas go out to work all the year round. , only the old, the weak, the sick, and the disabled stay behind in the village, and most of the snail inspectors are over 60 years old or illiterate. In this way, it is time-consuming and laborious to use manual snail inspection, and there will be problems of missing inspections
