The soil compactness measuring instrument was developed by Top Instrument. The main models are TJSD-750 and TJSD-750-II. The same type of GPS soil compactness measuring instrument, which has a built-in GPS positioning and depth measuring system, can simultaneously display the soil compactness, measuring depth and geographical location, and can automatically generate the soil tightness of each measuring point after connecting with the computer. Solid curve. The current soil compaction tester can be used to measure soil compactness in the field. Compact soil can prevent the infiltration of water, reduce the utilization of chemical fertilizers, affect the growth of plant roots, resulting in reduced crop production. There is an old saying in the countryside, which roughly means: sowing cotton and kicking a pit. The pits and pits mentioned here are not to say that the geographical soil is soft and that one foot can step on a pit, but because the cotton sowing needs to compact the above soil after the soil is buried, otherwise it is not conducive to growth. This is the most convenient nature. It is to step on one foot. This is the source of one foot and one pit. In Xinjiang, there are large areas of cotton cultivation. In recent years, Top Cloud Yunnong has done a lot of agricultural production projects in Xinjiang. Naturally, our soil compactness analyzer has applications there, and even we have one. The customer is cotton, and the customer places special emphasis on our soil compactness tester. In order to obtain higher product and crop quality, modern agricultural production often requires the best possible control of all aspects of crop growth, so our soil compactness tester is also used by customers to sow cotton seeds. Some people may question, do I have to test each pit seed sowing? In fact, this is not the case. We only need to put a certain amount of soil in a container with a unit area, then sow the seeds, and then use different weights to press the same amount of time on the soil surface per unit area. After this test, record the data and observe. In the latter stage of the seed germination, it is possible to determine how much tighter the soil is most conducive to the production of the cotton seed. After that, our cotton planters can directly use the forceful tool to compact the soil on the seed pit. In order to ensure the correctness of the work, a certain amount of spot checks should be performed after sowing. Through this example also let us understand that the soil compactness tester can not only determine the soil physical properties including soil texture, structure, porosity, etc., involving soil solidity, plasticity, permeability, drainage, impoundment Ability, difficulty of root penetration, etc. It can also be used on the sowing of cotton, which is another new use of the product.
Design, production and inspection carry out the latest issued relevant national standard, equivalently adopts some foreign criteria including FEM, DIN and IEC. Compared with the general QD Bridge Crane ( Overhead Crane), its weight is reduced by about15-30%. the max. Wheel pressure is reduced by about10-35%. which can be the requirements of crane for the factory building structure and reduce production cost. As the core component of driving mechanism, reducer gear pair with hard tooth surface and high accuracy. Together with steel reel, forged wheel and variable- frequency speed regulating system, which makes this type of crane become renewal product of traditional general bridge crane in industry of machinery production, assembling, petrochemicals. Warehouses logistics, electric power construction, papermaking and railway
There are different kinds for such New Type Crane: European type overhead crane, European Single Girder Bridge Crane, European Double Girder Bridge Crane and Kbk Crane
