It is needed by the breeder and the owner of the garden plot, things will go faster from the bliss when harvesting in student production teams and on home mini-farms. Yes, and when carrying out school programs of experimental work - those sections that are devoted to studying the influence of various factors on the yield of grain crops - a small but productive threshing machine will bring considerable benefits. After all, harvesting without losses, determining the yield is the most important final phase of the agricultural season.

Here is one of the possible options for a threshing machine. The unit built by us is easy to manufacture, convenient to use, and highly productive. Its design ensures good threshing and does not crush plant stems.

The thresher is set up like this. A ZID 4,5 engine with a gearbox is fixed on a frame made of angle metal, reducing the speed of the drive to about 30-40 per minute. A massive flywheel is mounted on the output shaft of the gearbox, and four rods with annular grooves at the outer ends are welded to it. They are stretched and secured with a knitting wire "beat" - rubber tubes 550-500 mm long (we used pieces of decommissioned high-pressure hoses from the hydraulic systems of serial agricultural machines).

The thresher drive can also be provided with an asynchronous electric motor with a power of about 1 kW or any low-power internal combustion engine. To protect workers from injury, the rotor of the unit is protected by a wire mesh with a diameter of about 6 mm.

Electric variant

Use a threshing machine like this. The sheaf is placed on a platform of rubberized fabric. When the rotor rotates, the beaters whip the sheaf, knocking out the grains from the ears.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Microplastics end up in food 07.06.2019

The average person eats at least 50 microplastics a year and breathes in the same number more. This is evidenced by data from a scientific study at the University of Victoria in Canada.

Researchers report that in fact, the amount of plastic ingested by a person can be much higher. Since a small number of products were analyzed for plastic content in the study. For example, drinking bottled water will dramatically increase the rate.

At the moment, the exact effect of plastic on the body is still unknown, but it is very clear that microparticles are capable of releasing toxic substances. Also, some pieces of plastic are small enough to penetrate human tissue and trigger an immune response.

Microplastic air pollution comes from the decay of plastic waste, which is abundant all over the planet.

The scientists analyzed 26 previous studies that analyzed the content of microplastics in fish, shellfish, sugar, salt, beer and water, as well as in the air within cities.

Researchers estimate that adults eat about 50 micropalstic particles a year, and children about 000.

But most of the products have not been tested. Scientists suspect that the content of plastic in foods such as bread, meat, dairy products and vegetables may be even higher.
