High-yield and high-quality rice has always been a production target in the agricultural field. In order to achieve this goal, various types of operations such as variety improvement, water and fertilizer optimization, etc. have been performed, and at the same time, one of the most critical sites for root growth of rice has not been forgotten, and roots have been used. The analyzer carried out related research work. It can be said that the root system is the bridge between the plant and the soil for material exchange and information exchange. It is essential for the growth and development of the plant. Therefore, using the root analyzer to analyze the root system of rice is to regulate the root system of rice by analyzing the characteristics of the root system. The growth and development, and then achieve the purpose of improving rice yield.
Since the roots of rice directly affect the growth and development of the aboveground parts and the formation of yield, it can be said that the rice root system is a key factor restricting the further development of the yield potential of high-yielding rice. Therefore, with the development of science and technology, agricultural scientific research workers certainly cannot Abandon this important link and actively use the root analyzer to provide data materials for high-yield rice research. By improving agronomic practices, optimizing the structure of water and fertilizer, promoting the formation of good root morphology, and providing reliable guarantees for achieving high rice yield, increase rice yield. At the same time, reduce fertilizer use, reduce pollution to the environment, and promote high-yield and high-quality cultivation of rice.
In addition, the application of the root analyzer also provides support for strengthening the genetic research of rice roots and carrying out rice root breeding. This helps breeders with a high utilization rate of fertilizers from roots, good lodging resistance and rice quality. The varieties with good promoting effect, slow aging, strong functions, drought resistance and salt tolerance can not only greatly promote the development of rice breeding, increase the yield and economic benefits of rice cultivation, but also will be comprehensive and sustainable for the rice industry in China. Balanced development plays a good role in promoting.
1. What is cement bulker?
Bulk Cement Trailer is also called cement bulker, silobas or silo trailer. It is mainly used for the bulk packing of powder dry materials such as fly ash, cement, lime powder, ore powder, granular alkali, aluminum powder, etc. transport. We often see bulk cement tank Semi Trailer for the transportation of powdered materials at cement plants, cement warehouses and large construction sites. And bulk feed tankers for sale.
It adopt pneumatic discharge, the vertical height of the discharge can reach 25m, and the fastest discharge speed can reach 1.5 tons / minute.
(1) What are the common types of all bulk tankers?
V type bulk cement truck, W type double warehouse bulk tanker trailer and Horizontal bulk cement tanker
(2) What is the tonnage and volume of the cement tanker trailer?
The bulk cement tanker trailer for export to Uzbekistan and Africa are mainly used to transport 30 tons, 40 tons, 45 tons and 80 tons of cement.
The main volumes of silo semi trailer for export to Africa and South America are 25 cubic meters, 30 cubic meters, 35 cubic meters, 38 cubic meters, 40 cubic meters, 50 cubic meters, 60 cubic meters, and 80 cubic meters.
2. Sealability test of silobas for transportation of powder materials.
Cement bulker trailer will be tested for airtightness after the production is completed. The tank is compressed to 0.2MPa by air compressor. If the air pressure does not decrease after 12 hours, the next production will be carried out.
If the air pressure after 12 drops, the tank needs to find the welding defects and re-weld, and then conduct the leak test again.
3. Package and transportation of bulk cement trailers for sale.
In order to prevent the vehicle paint from being corroded by seawater, we spray a layer of wax on the surface of the pneumatic sand trailer before shipping, and then seal it with a waterproof rain cloth.
We will wrap diesel engines of all bulk cement semi trailer with rain cloth.
4. What is the working principle of cement tanker?
Working Principle:
The cement transport vehicle uses its own engine to drive the on-board air compressor, and sends compressed air through the pipeline to the air chamber at the bottom of the sealed tank, so that the cement on the fluidized bed is suspended in a fluid state. When the pressure reaches the rated value, the discharge valve is opened, and the fluidized cement is transported through the pipeline for transportation.
Design Features:
Only by the world`s most advanced manufacturing process, the design is novel, durable. The air bag type has a large carrying capacity, fast discharge speed and small residual quantity. The integrated tank body has the characteristics of high overall strength, good rigidity, good pressure resistance.
The fluidized bed in the tank is scientifically designed and reasonably arranged, which can effectively shorten the discharge time to 1.4T / min, which improves the volume utilization rate of the tank and reduces the residual ash rate, which is 0.2%. The tank body of the silobas trailer adopts a double-cone inclination horizontal structure, double-tube intake and double-barrel feeding, and its discharge speed and remaining rate meet the requirements of industry standards.
5. How does dry bulk trailer load powder materials.
(1). Before opening the feeding cover, you must open the pressure relief valve and the inlet pipe ball valve to remove the remaining air in the tank before opening the tank cover to avoid injury.
(2). You should always pay attention to whether the pressure gauge is working properly, to prevent the pressure gauge from malfunctioning and overpressure, and the tank bursting.
(3). Always check the safety valve to ensure that the pressure is released at 0.2Mpa, and the pressure inside the tank must not exceed 0.2Mpa.
(4). Often check whether the operation table is working properly, so as not to overrun and damage the air compressor.
(5). Always listen to the sound of power take-off and air compressor rotation. If there are abnormal sounds, stop troubleshooting immediately.
6. How does dry bulk tanker trailer unload powder materials?
(1). Before unloading, check whether the unloading disc valve, external air source interface, exhaust valve and two feeding ports are closed and tightened. If they are not tightened, tighten them first to prevent air leakage;
(2). Start the engine and shift the transmission to neutral while pressing the clutch pedal to completely separate the transmission from the engine;
(3). Turn on the power take-off solenoid valve switch, and slowly release the clutch pedal to rotate the air compressor.
(4). Adjust the control handle of the control mechanism to adjust the speed of the air compressor to about 900r / min and stabilize it;
(5). When the pressure reaches 0.18MPa, first open the auxiliary blow pipe, then open the front and rear bin discharge disc valves to start discharging, after which the pointer of the air compressor will stabilize to a certain value;
(6). When the air pressure drops to 0.04Mpa, the back bin has been unloaded. Close the blower tube, open and close the back bin valve several times, and then close the back bin valve and the back bin intake valve. After which the pressure will rise and stabilize to a certain value;
(7). When the pressure of the barometer reaches 0MPa, the discharge is completed, the air compressor is closed, and the discharge disc valve is closed.
7. How to maintain powder tanker trailers?
(1). Air compressor: According to the instructions of the air compressor. Be sure to add lube before use!
(2). Engine: Pay attention to regularly check its lubrication and operating conditions. If there is any abnormal noise, the cause to identified and eliminated in time. The gear meshing and wear should check once a year, and it should not run at high speed.
(3). Gas path: The sealing condition should be checked frequently, and if there is air leakage, it should be removed in time.
(4). Tank body: Regularly check the tank body for leaks.
(5). Tank air chamber: Check the air chamber canvas frequently. And check whether the air chamber bead is compacted.
