Rotary cultivator use 1. Correct selection of rotavator knife shaft speed and tractor speed. In order to ensure that the rotary cultivator can meet the agronomic requirements during the operation, the forward speed of the dry tillage operation is 2~3km/h, and the operation of the water tillage or hoeing can be 3~5km/h. For the rotation speed of the rotary cutter shaft, the low speed gear is generally used for paddy farming or tilling with relatively large resistance, and the rotation speed is about 200 rpm. When the soil with relatively small specific resistance is used for hydroponic, alfalfa and tillage High-speed gears are used, and their speed is generally around 270 rpm. 2. Rotary tillage operation. Because there are two forms of the hydraulic suspension device and the structure of the power output shaft of the tractor, the rotary cultivator is different in the lifting operation. One is that the tractor hydraulic suspension mechanism and the power output shaft are respectively driven (such as Taishan-50, Dongfeng-50, Shanghai-50 and other tractors). Regardless of whether the power output shaft rotates, the rotation of the rotary tiller is not affected by the power output shaft. . Another type of tractor's hydraulic suspension mechanism and power output shaft are linked (such as the Harvest-27 tractor). With this model, the rotary cultivator can only be lifted when the power output shaft is rotated. When this kind of tractor is working in the field, if the cutter blade is stuck in the mud, the cutter shaft will not move, the tractor will be extinguished due to the heavy load, and the rotary tiller will not rise. At this moment, the power output shaft should be Remove the joints and allow the power output shaft to idle and lift the rotary tiller.
Rotary cultivator adjustment 1. Adjustment of the chain. Chain adjustment should pay attention to the looseness of the chain and the phenomenon of chain climbing, too tight will increase the wear and tear. When adjusting, pay attention to the force of the top tensioning slide rail should be within 5 ~ 10 kg, in order to be able to pressure the loose edge chain is appropriate, if the pressure does not move, then the chain is too tight. 2. Adjustment of bearing clearance. There are two ways to adjust: First, increase or decrease the shims. For bearings with fixed inner ring and adjustable outer ring, the axial clearance can be adjusted by increasing or decreasing the gasket at the bearing cover. After checking the adjusted bearing clearance, if there is no measuring instrument and special tool, the shaft can be turned by hand according to experience. There should be no obvious axial turbulence and rotation is flexible. If it is too tight and the rotation is difficult, the spacer should be added. Matsushita should remove the gasket. The second is the adjustment nut. All bearings that are fixed in the outer ring and adjustable in the inner ring can be used to adjust the axial clearance. The adjustment method (take a 1-meter rotary cultivator as an example) is: tighten the round nut of the big bevel gear first, lock the thrust washer, then tighten the other end of the round nut and rotate the bearing by hand until it cannot rely on the inertia force Then turn, and then hit the shaft with a wooden hammer head, so that the bearing inside and outside the ring close, and then review the bearing preload situation, adjusted and locked with a locking nut.
Maintenance of major components 1. Machete. The blunt machete should be re-sharpened, the deformed machete must be cushioned, and then quenched (the handle part is not hardened). The hardened machete hardness should be HRC50-55. If it is damaged, it should be replaced with a new one. 2. Tool holder. The damage of the tool seat is mostly de-welding, cracking or hexagonal hole deformation. The partially damaged tool holder can be repaired by the welding rod, and the damaged one should be replaced. But when welding the tool holder, pay attention to the deformation of the tool shaft. 3. Tool shaft tube. Broken knife shaft tube can put a piece of round steel with good weldability in the tube at the fracture. After welding, artificial aging and straightening should be performed. Then check the bearing shields at both ends. If the overshoot is too large, replace the end with no spline. The shaft head should be based on the original spline end diameter as the basis for processing the new shaft head to ensure that the knife shaft rotation and balance.
Veterinary Drug Preparation For Pets
Medicine for pets.,including antibiotics, hormones, feed, vitamin nutrients, etc.
Veterinary drugs refer to substances (including drug feed additives) used for prevention, treatment, diagnosis of animal diseases or purposeful regulation of animal physiological functions.
Veterinary drugs can be roughly divided into four categories: â‘ general disease prevention and treatment drugs; â‘¡ Drugs for prevention and treatment of infectious diseases; â‘¢ Drugs for prevention and treatment of internal and external parasitic diseases; â‘£ (including growth promoting drugs). Except for the biochemical immune products (vaccine, vaccine, serum, antitoxin, toxoid, etc.) for the prevention and treatment of infectious diseases, as well as special veterinary drugs for livestock and poultry parasitic diseases and growth promoting drugs, the rest are the same as those for human use, but the dosage, dosage form and specifications are different. It has long been widely used in the prevention and control of livestock and poultry diseases.
More than 20 kinds of veterinary drugs are commonly used, such as analgin, amoxicillin, florfenicol, ceftiofur, oxytetracycline, chlortetracycline, bacitracin, salinomycin, monensin, colistin, etc. 60% of antibiotics were used in chemotherapy; 40% is used as feed, which can not only prevent infectious diseases, but also promote the growth of livestock and poultry and improve the utilization rate of feed.
Among the Antiparasitic Drugs, in addition to the common anti helminth drugs (mebendazole, levamisole, thiadiazine, etc.), anti schistosomiasis drugs (antimony agent, nithiocyandiamide, praziquantel, etc.) and anti tapeworm drugs (niclosamide, etc.), the special anti Fasciola hepatica drugs (nitrochlorophenol, trichlorobenzole, etc.), Trypanosoma, and pyroplasmosis drugs (antracel, suramin, chloramphenicol, etc.) for livestock and poultry are also used Imidacloprid and other insecticides (organophosphorus insecticides). A macrolide antibiotic was found to have a significant killing effect on parasites such as gastrointestinal nematodes, Dermatophagoides, blood sucking lice, especially Sarcoptes scabiei. Coccidiosis is a serious threat to the safety of chickens and rabbits. There are more than 30 kinds of commonly used anticoccidial drugs, including synthetic drugs (such as chlorobenzoguanidine, changshanone) and antibiotics (such as monensin, salinomycin), which are often used alternately.
Biochemical immune products are mainly used to prevent animal anthrax, brucellosis, anthrax, salmonellosis, and a variety of viral infectious diseases.
Injections are commonly used in veterinary drug preparations, but their specifications are several times larger than those for human use. Oral veterinary drugs are usually in powder or microcapsule form, as feed additives, mixed into the feed for free feeding of livestock and poultry. Anabolic hormone can increase the benefit of raising livestock and poultry. It is mainly made into implant for subcutaneous implantation. Transdermal preparations and medicated baits for aquaculture are emerging.
