From scratch, from extensive to precise, the changes that have taken place in China's agricultural sector are obvious to all. Once, the vast numbers of farmers faced the climate change of nature, and they were helpless. However, with the help of sophisticated meteorological instruments such as hand-held meteorological instruments, they have mastered meteorological changes, realized meteorological services for agriculture, and allowed meteorological production of agricultural products and agricultural production. The trend can be completely grasped by ourselves. The agriculture that eats in the sky is gradually developing into an intelligent agriculture that can be chosen independently.

In response to changes in the climate environment, it is important to have sufficient and accurate meteorological data. If temperature, humidity, illumination values, wind direction and wind speed can be accurately grasped, farmers can respond in advance to avoid losses and reasonable. Arrange for production, and carry out farming work in a timely manner. Handheld meteorological instrument is a powerful "weapon" for modern farmers to collect and record and apply meteorological data for agriculture. The instrument can detect meteorological elements such as temperature, humidity, rainfall, wind direction, wind speed, soil temperature and humidity, and illumination. The weather monitoring data is recorded and displayed by the host computer, and can also be imported into a computer for viewing. Handheld meteorological instruments provide first-hand information for crop growth, defense against agrometeorological disasters, and special meteorological services.

In the past, farmers could only rely on their own experience and general weather forecasts to cultivate cultivation and field management, and this rough management model is clearly not suitable for modern agricultural development. The modernization of agriculture needs to be equipped with specialized meteorological observation services. With the help of scientific meteorological instruments such as handheld meteorological instruments, technicians can conduct high-frequency, high-accuracy real-time meteorological environment monitoring and analysis on a regular and irregular basis, using accurate Meteorological data guide farmers' production labor, make agricultural production more refined and scientific, and accelerate the transformation of traditional agriculture to modern agriculture.

Lifting Jack

Jack is one of the most simple lifting equipment with lifting height of less than 1 m, using jacking rigidity as a working device, through the top bracket or hold claw in the schedule at the bottom of the light and small lifting heavy lifting equipment.Divide into two kinds, mechanical and hydraulic jack is mainly used in mines, transportation and other departments as vehicle repair and other lifting, support, etc.The structure light and strong, flexible and reliable, one man can carry and operation.

Jack is divided into mechanical jacks and hydraulic jack, principle is different. In principle, the principle of hydraulic jack is based on PASCAL's principle, namely: the liquid pressure is the same everywhere, so, in a balanced system, the smaller piston top pressure is small, and the big pressure on the piston is bigger, it can keep the liquid stationary. Through liquid, so can be different on the different pressure, so that you can achieve the goal of a transformation.We are common to the hydraulic jack is to use the principle to achieve the force transfer.Mechanical jacks, using mechanical principle, in the past after pull (handle, claw namely rotary driving ratchet clearance, pull small bevel gear drive big bevel gear, make weight lifting screw rotation, so that the lifting socket for lifting or falling, and achieve the function of the lifting force. But not as easy hydraulic jack.
