The process of transportation of any cargo always consists of three components: loading, delivery and unloading. Suppose the cargo has already been transported to the farmyard. The moment of unloading comes - it usually happens here manually, rarely when it is possible to use a crane, except for removing some large-sized weights from the vehicle.

And all by hand! The work is laborious, whether it is bulk cargo or piece. Here the question of "mechanization of the process" involuntarily arises.

I took up this as well. I decided to design a small "self-dumping" trailer for a tractor with a carrying capacity of 2 - 3 tons. As strange as it may seem, my first glance was fixed on ... a kvass barrel. Officially, it is called the ATsPT-9 tank trailer for transporting kvass. Of course, I considered only the trailer itself, its frame, which can withstand a barrel of kvass with a total mass of about a ton.

As it turned out, it was created on the basis of a single-axle tractor trailer 1-PT-1,7. With its own weight of 0,8 tons, it was possible to carry cargo up to 1,8 tons on such a trailer; the mounting platform - 2484x940 mm - was also quite sufficient to accommodate the trailer body I had planned.

For the manufacture of the trailer frame, I picked up metal profiles similar to the channels on the frame: the front traverse with a section of 100x46x5 mm, side spars (to avoid the occurrence of longitudinal bends when passing on uneven roads) - more powerful - with a section of 140x58x5 mm; the rear beam, which accounts for most of the mass of the load when lifting the body, is 120x52x5 mm. The frame in diameter was reinforced with a central beam of a slightly smaller section - 100x100x4 mm. In addition, he secured the connection of the rear beam and spars with scarves. Thus, a metal frame with dimensions of 1800x1700 mm was obtained, all the joints of which are welded.

Scheme of the body frame (click to enlarge): 1 - side post (channel 500x50x5); 2 - stringer (channel 120x52x5); 3 - spar (channel 100x46x4); 4 - loop; 5 - floor trim (corner 80x80x6)

As a hydraulic cylinder, I used a 1PTS-9 tractor trailer lift. The stroke of its rod is 850 mm, which made it possible to raise the body at an angle slightly more than 50 °, sufficient for complete sliding from the ground.

However, in order to install a hydraulic cylinder on the frame, it was necessary to make a truss in the form of an inverted truncated triangle - a brace - from a channel with a section of 120x52x5 mm. On the resulting bottom platform of the brace with a width of 300 mm, I placed a hydraulic cylinder. As a stop in the upper part, I used a metal circle with a diameter of 650 mm, welded to the details of the body frame. I connect the hose directly to the tractor hydraulic system. The strut clearance is 300 mm.

It took a little longer to tinker with the drawbar. The wheels of the cart - from GAZ-53 (8,25R20) - have a diameter of 962 mm, and it turned out that when connected to the tractor, the frame was not installed in a horizontal position, but with a significant slope. I had to "lower" the drawbar, and for this, a 100x45x4 mm channel was welded under it, in addition, a trailed thrust plate with dimensions of 150x20 mm was put in front. After that, the frame "flattened".

Front part of the frame: 1 - front traverse; 2 - drawbar; 3 - transverse amplifier; 4 - shook; 5 - emphasis

Then I moved on to building the body. This is where things moved faster. Stringers and spars, again from channels 120x52x5 mm and 100x46x4 mm, laid in a honeycomb pattern at a distance of 550 mm and 600 mm on the floor strapping from corners measuring 80x80x6 mm. From above covered with sheet iron 2 mm thick. I hung the boards with a height of 600 mm from edged boards measuring 150x25, fastened them with vertical metal strips measuring 500x55x5 mm. In the corners they are locked with conventional side locks.

The rear stringer of the body is fixed in the hinges of the rear frame beam.

It should be noted that in order to balance the center of gravity, the body had to be shifted in the horizontal plane by 200 mm forward from the axis along the frame.

Body size - 2500x 2000 mm. I place the load in it, as I planned, about 2,5 tons.

For several years, the trailer has been doing its job perfectly without any breakdowns or failures. I mainly transport bulk cargo, but I also have to load the trailer with hay, teddy grass, and also "iron".

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 ... >>

Most young people watch their body for the sake of social networks 19.08.2016

Most young people monitor their body tone in order to post pictures of it on social networks. This is evidenced by the results of studies conducted by specialists from the University of East Anglia.

According to scientists, the trend of attending gyms and constant diets among young people began to gain popularity in the early 90s. It was then that most young people had the opportunity to use blogs and the first social networks to publish their pictures. In most cases, this study focuses primarily on girls who take care of their bodies in order to be sexy and attractive among their peers.

Scientists note that it is the Internet and television that influence young people who strive to be sexual. Seeing attractive bodies in sports stars and erotic films, boys and girls try to imitate them. In this regard, there is a need for classes in gyms and constant diets, which can lead to negative consequences at an early age.

In the course of research conducted by scientists from the University of East Anglia, it was possible to establish that approximately 55 percent of all boys and girls surveyed go in for sports solely in order to look sexy and attractive on their pages on social networks. In addition, about 20 percent of them drink alcohol and smoke, which affects their body. Only 35 percent of those surveyed said that they go in for sports solely for the sake of improving their health.
