Common agricultural machinery terminology

1. Agricultural mechanized agricultural mechanization is a process in which machinery and equipment are used instead of manpower and animal husbandry to carry out technological transformation and economic development of agricultural production. Agricultural mechanization includes planting, aquaculture, and mechanization of the processing industry. It covers the whole process of pre-production, production, and post-production. The purpose of agricultural mechanization is to use modern engineering technology to equip agriculture, achieve high quality, high yield, and high efficiency in agriculture and ensure the sustainable development of agriculture.

2. Mechanized level The number of machines and equipment used in agricultural production accounted for the percentage of the total operating volume, which is generally calculated according to the operating items.

3, supporting the agricultural (machine) with the width, size and size of the power required to drive or drive it to work tractor or power machine power and overall dimensions of agricultural machinery fully adapted. If equipped with Dongfanghong-54 tractor, Wuling Plow 1L−5−35. The use of supporting agricultural machinery can avoid wasted power of the power machine, and give full play to the working capacity of the agricultural machinery.

4, technical maintenance referred to as maintenance. Periodically systematically inspect, clean, lubricate, tighten, adjust or replace certain parts of agricultural machinery. The purpose is to ensure the mechanical state of the machine, the life of the director, and the prevention of failure and damage.

5, regular technical maintenance referred to as regular maintenance. The maintenance performed by agricultural machinery after completing a certain amount of work hours, fuel consumption, or workload. The regular maintenance of the tractor is divided into No. 1, No. 2, No. 3 and No. 4. The first and second are called low maintenance, and the third and fourth are called high maintenance. The grain combine harvester is divided into maintenance number one and number two. The period of high technology maintenance of the tractor is often an integral multiple of the low maintenance period, and includes all the items and contents of low maintenance. The contents of technical maintenance of each number are clearly stipulated in the technical maintenance regulations or instruction manuals of various agricultural machinery.

6. Each class of maintenance of agricultural machinery to complete maintenance after a class work. Including dust removal, check and tighten bolts and screws; check and tighten the tractor's air filter, fan, water tank, lamp holder and fuel tank, check for oil leakage, water leakage, inspection gearbox and final drive Heat; refuel, add water; lubricate each part.

7, double class technical maintenance referred to as double class maintenance. Technical maintenance performed jointly by the shifter and the successor farmer. The advantage is that it can make the personnel responsible for the transfer of the locomotive responsible for the technical state of the machinery, facilitate the clear explanation of the technical status of the machinery, reduce the failure, and improve the maintenance efficiency.

8. Do not disassemble the inspection instrument (pressure gauge, flow meter, etc.) to check the technical status of the tractor and engine to determine if it needs to be repaired or to determine the cause of the malfunction without dismantling the tractor and the engine's parts and components.

9. Attendance The number of times the tractor is out of operation (including temporary faults, maintenance within the class, and land transfer time) reaches the time specified in one shift is called an attendance shift. General provisions of 10 hours for a shift attendance.

10. Tractor attendance rate The ratio of actual attendance and planned attendance shifts for each quarter or year of the tractor is called the quarter attendance rate and the annual attendance rate, expressed as a percentage.

11. The ratio of the number of tractors in good condition and the number of the total number of tractors in good condition is expressed as a percentage.

12. Time Utilization Ratio The ratio of pure working time and total time per shift of the tractor in each shift is expressed as a percentage.

13, tractors "armpit"

The tractor cannot work. Parking for more than two months is called "armpit."

14. Tractor productivity The workload per unit time of the tractor is usually expressed in terms of shift productivity (mu/shift), net working hour productivity (mu/h), and horsepower hour productivity (mu/hp 1 hour).

15, standard acres (folded mu)

The basic unit of calculation for the amount of work accomplished by tractors and supporting agricultural implements. One standard mu is the workload of cultivating one mu of ripe land under conditions with a specific resistance of 0.5 kg/cm2 and a tillage depth of 20–22 cm. Various other different operations can be converted into standard acres by using the corresponding conversion factor. The coefficient of ripening is determined by the ratio of the productivity of various operations to the productivity of the cultivation under standard conditions. For example, if the nails are pounded once, the coefficient of ripening is 0.1. If the disc is pounded once, the coefficient of ripening is 0.3. In compound work, the coefficient of ripening shall be added. For example, under the standard conditions, plowing with nails and tines, the fatigue coefficient is 1+0.1=1.1. The fatigue coefficient of various operations is awarded by the relevant authorities.

16. The amount of main fuel consumed by a standard mu fuel-efficient tractor to complete a standard mu operation (excluding the gasoline consumed by starter gasoline engines) is measured in kilograms.

17. Standard acres cost The sum of the expenses incurred by a tractor to complete a standard MU operation, which generally includes the production personnel's labor remuneration, fuel charges, maintenance fees, overhaul savings, basic depreciation and operating management fees.

18. Fixed-operation agricultural implements work at a fixed location. Such as pump pumping, threshing machine in the field threshing and processing of agricultural and sideline products.

19. When duplex tractors are used to drive agricultural implements, two or more operations are completed at one time. For example, the tractor can pull ploughs and rakes to complete arable and sloping operations. Duplex operations can compete for agricultural time, increase labor productivity and reduce operating costs.

20, rated speed (calibration speed)

The speed of the crankshaft specified by the manufacturer when the internal combustion engine emits rated power. The unit is RPM.
