The "Four Preventions" Should Be Doed Well during the "Renang Vacation" of Farm Machinery
The use of agricultural machinery is affected by the seasonality. It has been idle for a long time. In order to prolong the service life of agricultural machinery, the following “four preventions†should be implemented during the idle period of agricultural machinery.
First, anti-corrosion
1. After the agricultural machinery is completed in the field, it is necessary to remove the external dirt, clean up the seeds, fertilizers, pesticides and stubbles from the working organization, and clean it with water or oil if necessary.
2. Clean all lubrication points and re-lubricate. For all friction surfaces, such as ploughshares, openers, spade shovels, etc., must be wiped and coated with oil, preferably with stickers to reduce the chance of contact with the air.
3, sophisticated and accurate tools are best kept in a cool, dry, ventilated indoor storage; simple equipment such as ploughs, rakes, and suppressors can be kept in the open, but should be placed on a high ground, dry, out of direct sunlight , It is best to cover the roof; any parts that come in direct contact with the ground should be supported by planks or bricks; the protective paint that has fallen off should be repainted.
Second, anti-corrosion, mildew
1. Wooden parts are rotted, cracked and deformed due to the action of microorganisms, as well as rain, wind, and sun. The effective method of protection is to coat the exterior of the wood with paint, place it in a dry place, and avoid sun exposure. Rain.
2, textiles, such as canvas conveyor belt, improper storage and mildew. Such products should not be placed in the open air, they should be removed after cleaning and drying, and stored indoors in a dry and pest-proof and rodent-proof place.
Third, anti-deformation
Parts such as springs, transmission belts, long shanks, and tires will be plastically deformed due to prolonged stress or improper placement. To this end, proper support shall be provided under the rack; the tires shall not be subjected to load; all pressing or pulling on the machine The springs must be loosened; the removed belts are kept in the room; some of the dismountable parts, such as the long knife bar, must be laid flat or hung; and the parts removed, such as tires, seedlings, etc., must be prevented from being stored. , squeeze, pressure deformation.
Fourth, anti-aging
Due to the oxygen in the air and the ultraviolet rays in the sunlight, rubber and plastic products are susceptible to ageing and deterioration, making the elasticity of the rubber parts poor and easily broken. For the storage of rubber parts, it is best to use hot paraffin oil on the surface of the rubber, be sure to put it on the indoor shelf, cover it with paper, keep it ventilated, dry and free from direct sunlight.
Antiparasitics are a class of medications which are indicated for the treatment of parasitic diseases such as nematodes, cestodes, trematodes, infectious protozoa, and amoebas.
Antiparasitic drugs are used to inhibit, kill or expel parasites in and out of animals. Most of the ancient antiparasitic drugs originated from natural plants and animals. Most of them have been eliminated because of their weak antiparasitic effect or high toxicity. The progress of modern science and technology has accelerated the development of pharmaceutical industry, and the variety and quality of antiparasitic drugs are increasing. At present, a large number of new, efficient, broad-spectrum and adaptive antiparasitic drugs have been developed. Antiparasitic drugs are usually divided into Anti helminth drugs, insecticidal drugs and antigenic drugs. According to the species of helminths parasitic on livestock, anti helminth drugs can be divided into nematicides, tapeworms and trematodes. At present, the commonly used antiparasitic drugs are: 1) nematicides: levamisole, tetraimidazole, thibendazole, mebendazole, thiadiazine (Kangchongling), tetrachloroethylene, ivermectin, etc; ② Anti tapeworm drugs: praziquantel, niclosamide (miezaoling), dichlorophenol, areca, etc; ③ Anti filariasis drugs: thioarsenamine sodium, iodothiazide, dichlorophenylarsine and Di, antimonol, etc; ④ Fluke repellents: Nitrazine, Nitrazine, hexachloro-p-xylene, praziquantel, etc; ⑤ Antigenic agents: chlorphenamidine, aminopropyl, benzoquinoline, shachongling nitrobenzamide (Qiuliling), etc; ⑥ Insecticides: trichlorfon, fenthion, phoxim, oxyphos, dimethamidine, etc.
