Each professional industry will have its own industry terminology, and the agricultural machinery industry is not listed. To understand the agricultural machinery industry, we must first understand some of the technical terms related to agricultural machinery in the agricultural machinery industry.

1. Agricultural mechanization

Agricultural mechanization is the process of technological transformation and economic development of agricultural production by replacing human and animal power with machinery and equipment. Agricultural mechanization includes mechanization of planting, aquaculture and processing industries, which runs through the whole process of pre-production, mid-production and post-production. The purpose of agricultural mechanization is to equip agriculture with modern engineering technology to achieve high quality, high yield and high efficiency of agriculture and to ensure the sustainable development of agriculture.

2, mechanization level

The number of machines and equipment used in agricultural production accounts for the percentage of the total work volume, which is generally calculated separately for the work items.

3, supporting agricultural (machine)

The width, dimensions and power required to match the power and form factor of the tractor or power unit that drives it or that drives it. Such as the five-plow 1L-5-35 with Dongfanghong-54 tractor. The use of supporting agricultural machinery can avoid the power waste of the power machine and give full play to the working ability of agricultural machinery.

4, technical maintenance

Referred to as maintenance. Regularly inspect, clean, lubricate, tighten, adjust or replace parts of agricultural machinery. The purpose is to ensure the good technical state of the machine, the life of the director, and prevent malfunction and damage.

5, regular technical maintenance

Referred to as regular maintenance. Maintenance of agricultural machinery after completion of certain working hours, fuel consumption or workload. The regular maintenance of the tractor is divided into one, two, three and four. The first and second numbers are called low number maintenance, and the third and fourth numbers are called high number maintenance. The grain combine harvester is divided into one and two maintenance. The cycle of the tractor's high technical maintenance is often a multiple of the low technical maintenance cycle, and includes all the items and contents of the low maintenance. The technical maintenance contents of each number are clearly defined in the technical maintenance procedures or instruction manuals of various agricultural machinery.

6, each class of technical maintenance

Maintenance of agricultural machinery after completing a class work. This includes removing dust, checking and tightening bolts and screws; checking and tightening the tractor's air filter, fan, water tank, lamp holder and fuel tank to check for oil leaks and water leaks. Check the gearbox and final drive section. Heat; add oil, add water; lubricate each part.

7, double class technical maintenance

Referred to as double shift maintenance. Technical maintenance carried out by the agricultural hand of the shift and succession. The advantage is that the locomotive handover personnel are responsible for the technical state of the machine, which is convenient for clearing the technical state of the machine, reducing the fault and improving the maintenance efficiency.

8, do not disassemble inspection

Use the 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 failure, without disassembling the tractor and engine parts and components.

9, attendance shifts

The time specified by the tractor for the time of the vehicle's departure (including temporary faults, in-class maintenance and transfer of the plot time) to reach one shift is called an attendance shift. It is generally stipulated that 10 hours is an attendance shift.

10, tractor attendance rate

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

11, the tractor integrity rate

The ratio of the number of tractors in good technical condition to the total number of units in total, expressed as a percentage.

12, time utilization

The ratio of the pure working time of the tractor to the total time of each shift in each shift is expressed as a percentage.

13, the tractor "armpit"

The tractor can't work, and it is called "armpit" for more than two months.

14, tractor productivity

The workload of the tractor per unit time is usually expressed in shift productivity (mu/shift), pure working hour productivity (mu/hour), and horsepower one hour productivity (mu/horsepower one hour).

15, standard acres (folding mature acres)

The basic unit of calculation for the workload of tractors and supporting implements. A standard acre is the workload of cultivating an acre of cultivated land under the condition that the specific resistance of the soil is about 0.5 kg/cm 2 and the depth of ploughing is 20-22 cm. A variety of other different operations can be converted into standard acres using the corresponding conversion factor (compromising factor). The folding factor is determined by the ratio of various job productivity to the productivity of the cultivated land under standard conditions. If the nails are twisted once, the folding coefficient is 0.1; the disc is smashed once, and the folding coefficient is 0.3. When working in duplex, the folding factor should be added. For example, under standard conditions, the plow belt is operated by a nail, and the folding coefficient is 1+0.1=1.1. The folding factor for various operations is determined by the relevant leadership department.

16, standard mu fuel consumption

The total amount of main fuel consumed by the tractor to complete a standard acre operation (excluding the gasoline consumed by the starting gasoline engine), in kilograms.

17, standard mu cost

The sum of the various expenses incurred by the tractor for completing a standard acre operation generally includes the labor remuneration of the production personnel, fuel costs, maintenance costs, overhaul, basic depreciation and operating management fees.

18, fixed operations

Agricultural machinery is carried out at a fixed location. Such as pump pumping, threshing machine on the field threshing and processing of agricultural and sideline products.

19. Duplex operation

When the tractor drives the agricultural implement, two or more operations are completed at a time. For example, the tractor pulls the plow and the hoe to complete the arable land and the hoeing operation. Duplex operations can fight for agricultural time, increase labor productivity, and reduce operating costs.

20, rated speed (calibrated speed)

The speed of the crankshaft as specified by the manufacturer and the rated power of the internal combustion engine. The unit is transfer/minute. (to the wire)
