1. Reasonable use of dividers and Fufu

In North China, South China and the central and western regions of China, the maturity of corn is about 110 days. When the corn is mature, the water content of the straw is still very high. Under normal weather conditions, the straw does not fall, and the ear has no sagging phenomenon. In the northeastern region, the maturity of corn is 150-180 days. At this time, the planting rate of corn stalks, the rate of ear sag and the rate of crop lodging are high. After analyzing the above situation, two suggestions were made for the operators who are preparing for the inter-regional operation: First, the dividers are only used in areas where the crop indicators are normal, and the second is that the Fuhe is only used for lodging crops.

2. Unloading food with a transport vehicle

A “two-way unloading device” was installed at the rear end of the elevator, a transport vehicle was hired, and the corn harvester was synchronized on the side, and the corn that was lifted by the lifter was thrown onto the transport vehicle through the outer exit of the two-way unloading device. In this way, the efficiency of the corn harvester can be improved.

3. Problems that should be paid attention to during work

(1) Before operation, it is necessary to check whether the fastening of the components is normal, whether the tension of the transmission belt and the chain is appropriate, and whether diesel, oil and hydraulic oil are in place.

(2) The clutch should be smoothly engaged during operation, and the throttle should be small to large until the stable rated speed can be started.

(3) When working in the field, check the cutting and crushing quality and the stubble height regularly.

(4) Judging the working state of the picking device according to the number of seeds thrown to the ground, the grain loss should not exceed 1% of the total amount of corn kernels; when the loss rate is increasing, it should be checked whether the working gap of the picking mechanism is normal.

(5) The corn harvester should be interrupted for 1 to 2 minutes in a timely manner, and the working parts should be idling to discharge all the corn ear, grain and other residues from the working parts, thereby reducing the blockage of the working parts.

(6) When the harvester is in operation due to overload, the running clutch and working clutch must be disconnected, and if necessary, the engine should be stopped.

4. Safety operation precautions

(1) When starting the machine, a signal must be sent to confirm that no one is nearby.

(2) It is forbidden to remove the safety shield when the harvester is running, working or transferring.

(3) Fire extinguishers should be provided and carried randomly. Always check whether the performance of the fire extinguisher is good. When encountering a fire, you should first think of using a fire extinguisher.

(4) When working under the picking table, the picking table must be reliably supported.

(5) Always check the reliability of the brake, steering and signal system. If abnormalities are found, they must be adjusted or repaired.

(6) When the harvester is working, it is strictly forbidden to stand behind the straw crushing and returning machine.

(7) When the harvester stops, the returning machine must be lowered to the ground.

(8) When the straw is crushed and returned to the field, the blade is prohibited from entering the soil.

Antimicrobials Drugs

Antimicrobial drugs are a class of drugs used to treat infections caused by microorganisms such as bacteria, viruses, fungi, and parasites. These drugs work by either killing the microorganisms or inhibiting their growth and replication include antibacterial drug,antimicrobial agents,antimicrobial medicine,broad spectrum antimicrobial.

There are several types of antimicrobial drugs, including antibiotics, antivirals, antifungals, and antiparasitics. Antibiotics are used to treat bacterial infections, while antivirals are used to treat viral infections. Antifungals are used to treat fungal infections, and antiparasitics are used to treat parasitic infections.

Antimicrobial drugs can be administered orally, topically, or intravenously. The choice of drug and route of administration depends on the type and severity of the infection, the age and health status of the patient, and the sensitivity of the microorganism to the drug.

However, the overuse and misuse of antimicrobial drugs have led to the development of antimicrobial resistance, which is a major public health concern. To prevent the spread of antimicrobial resistance, it is important to use these drugs only when necessary and to follow proper prescribing guidelines.
