Carbon dioxide is a gas that exists in the atmosphere, and its concentration has an impact on production and life. Since carbon dioxide is colorless and odorless, it is difficult to perceive, so the measurement of carbon dioxide content is mostly measured by means of a carbon dioxide detector . Here is a brief introduction to the detection principle of the carbon dioxide detector. The carbon dioxide detector developed by Top Yunong is mainly composed of a host computer and a sensor. The instrument is small and beautiful. The design is convenient for handheld operation. It can detect carbon dioxide at any time and place, and display functions such as color display, large-capacity storage and wireless transmission. The data viewing, preservation and analysis provide convenience and are the ideal instrument for the detection of carbon dioxide detectors in the field of agriculture and forestry. The detection principle of the carbon dioxide detector is generally to detect the carbon dioxide gas content of the on-site environment by the absorption principle of the infrared light source. Mainly based on the absorption of carbon dioxide on infrared light with a wavelength of 4270 nm, specifically, the gas to be measured is sucked into a measurement chamber, and one end of the measurement chamber is equipped with a light source and the other end is equipped with a filter and a detector. The function of the filter is only Allowing light of a particular wavelength to pass, the detector measures the luminous flux through the measurement chamber, and the luminous flux received by the detector depends on the concentration of the gas being measured in the environment. The above is the introduction of the detection principle of the carbon dioxide detector. This environmental monitoring instrument is not only widely used in agricultural planting. For example, in greenhouses, it is often necessary to use this instrument to monitor the concentration of carbon dioxide in the greenhouse and guide scientific production to ensure Safe and efficient growth of crops, etc. At the same time, it is widely used in animal husbandry, industry, public places and other fields. It is a powerful, wide-ranging, excellent and reliable gas environment monitoring instrument, which is trusted and welcomed by users.
The Loader linkage rod is the part connecting the Rocker arm of loader and the Loader Bucket. The pull rod of different models is mainly different from the center distance of two holes and the inner diameter of two holes
Structure of Loader Working Device
The working device consists of bucket, boom, beam, support, rocker arm, pull rod and so on. Each member is connected by hinge pin and has relative rotation. In order to enhance the stiffness of rocker arm and support, there is a rib plate connection between rocker arm and support, which can be regarded as a whole in calculation. The upper hinge point of the boom is hinged with the front frame of the loader, and the middle hinge point is hinged with the lift cylinder; The upper hinge point of the rocker arm is hinged with the bucket cylinder. In finite element static analysis with MARC, it is found that there is no relative rotation at each hinge of the working device. The boom is the main force component of the working device, and its section shape is rectangular. And because its length and width direction is much larger than the thickness direction, it can use plate shell element to discretize the boom. The cross beam is box shaped and welded.The rocker arm and support are also welded structures, and the cross-section of the welded plate is rectangular. Considering that the thickness of each component is much less than the thickness of the other two directions, it can be considered as plate parts.
