The proposed design consists of a float with an electric pump, which is lowered into a barrel of water intended for irrigation. The mechanical "heart" of the Eureka washing machine is used as a drive - an electric motor aggregated with a centrifugal pump. Its productivity is about 2000 l / h, which will completely satisfy the owner of any garden.

The float is cut out of a piece of dense foam and is a disk Ø 530 and 50-60 mm thick. In the center of it, recesses are made for the supporting bracket and the discharge pipe of the motor-pump, as well as through holes for the suction pipe and fastening screws. It is impossible to reduce the thickness of the float in order to bring the impeller closer to the water surface - it must provide buoyancy to the structure.

Floating pump device (click to enlarge): 1 - barrel, 2 - water mirror, 3 - float, 4 - bearing bracket, 5 - motor-pump mounting bracket, 6 - motor-pump, 7 - protective cap, 8 - handle- ring, 9 - watering hose, 10 - support clamp, 11 - outlet pipe, 12 - power cord, 13, 15 - pieces of rubber hose, 14 - discharge pipe, 16 - suction pipe

The supporting bracket is made of light aluminum alloy and is attached to the float with three Mb screws. The motor-pump mounting bracket is screwed to its vertical part with four M8 screws. The suction pipe, passed through the hole in the float, is lengthened with a piece of rubber hose so that the latter is immersed in water by 15-20 mm. The discharge pipe is connected by the same segment to a vertical outlet pipe Ø 20 mm, on which a watering hose is put on.

The motor-pump is protected from rain by a cap - a food-grade aluminum bowl attached to the bearing bracket with a ring-head bolt.

The structure is held by the ring when it is lowered into the container.

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 ... >>

Monkeys love music more than movies 25.06.2022

Scientists in Scotland and Finland have developed "animal versions" of Spotify and Netflix and have given monkeys the ability to turn on multimedia on their own. It turned out that the primates would rather listen to Arctic Monkeys than watch Planet of the Apes - they liked the music more than the movies.

The experiment took place at the Helsinki Zoo. It was attended by three pale saki - monkeys living in Brazil, Guyana, Suriname and Venezuela.

In three interactive zones of a special enclosure, scientists have placed infrared sensors. In this room, the primates could turn on a video or sound track on the screen. They were reproduced until the pale saki themselves turned them off.

It turned out that the monkeys included audio files twice as often as visual ones. That is, they preferred to listen to music rather than watch movies.

Among video files, primates more often chose scenes with the underwater world - they were competed with videos with worms and abstractions. Among the audio tracks, human-written music turned out to be the most popular, and not the sound of rain or the street.

The results of the study will help scientists maintain the mental health of captive animals.
