If the area on the left is 9 square meters, it will be cut in an hour.
The harvester was invented by Cyrus McCormick. Harvester This is a comprehensive machine for harvesting crops. Harvesting and threshing are completed at one time, and the grain is concentrated in the storage bin, and then transported to the transport vehicle through the conveyor belt.
You can also harvest by hand, spread the straws of crops such as rice and wheat in the ground, and then pick them up and thresh them with grain harvesting machinery. Crop harvesting machinery is used to harvest grains and straws of cereal crops such as rice and wheat. Include harvesters, lawn mowers, balers, grain combine harvesters and grain threshers. Grain harvesting machinery is developed on the basis of various harvesting and threshing tools.
1799 the first horse-drawn disc cutter harvester appeared in Britain; 1822, a reel device is added above the cutter. 1826, the prototype of modern reciprocating cutter and reel harvester appeared, which was pulled by many horses and driven by the rotation of the ground wheel. 183 1 ~ 1835, a similar animal-drawn wheat harvester became a commodity in the United States; 185 1 year, a rocker harvester appeared, which can collect the cut straw in piles. After 1920, due to the extensive use of tractors, harvesters matched with tractors began to replace animal-drawn harvesters. China began to produce animal-drawn rocker harvesters and other types of animal-drawn harvesters on 1952; 1962, began to develop mechanical horizontal header harvester and vertical header harvester with grass on the machine side. In order to meet the needs of harvesting wheat in the wheat-corn intercropping area in the north, 1977 developed a vertical header harvester with straw behind the machine.
The maintenance of harvester includes the maintenance of the whole machine and the management of small parts.
The sundries at the joint should be cleaned and lubricated or sealed with oil; If there are rust-prone parts exposed due to paint peeling, they need to be painted in time to prevent rust. If it is a rubber belt, it should be wiped and dried to prevent the harm of insects and rats; Metal chain can be cleaned with kerosene or diesel oil, and then soaked in engine oil 15-40 minutes, or soaked overnight. Take it out and dry it until it doesn't drip oil, coat it with softened oil, then wrap it in kraft paper and put it in a dry and ventilated place to avoid mildew and deformation.
There are also some rubber and plastic products on the harvester, which are easy to age and deteriorate after sun exposure and have poor elasticity, which will affect the use in the coming year. When storing these products, it is best to coat their surfaces with paraffin oil, and then put them in a ventilated and dry place that is not exposed to direct sunlight. Plastic products and springs will be deformed due to long-term compression or improper storage, so it is necessary to loosen the springs, disassemble the conveyor belt and store them separately.
In addition, some random instruments, especially special tools and various spare parts, need to be stored separately and put back in place after use to avoid being lost due to misplacement.
