Manual concrete mixer. Tips for the home master

Builder, home master

The prepared cement mortar needs constant stirring, otherwise it hardens quickly. But it's easy to say, but not easy to do; doing this work manually is extremely tiring - it is hard to lift a shovel with a solution. How would you try to spend your energy more rationally? So this device appeared in my household, facilitating work.

The design of a manual concrete mixer is extremely simple: four boards (made of hard wood) are fastened with T-shaped bolts and connected to each other by a bottom - a 1,5 mm thick sheet of tin. At the top of the racks, cutouts are made for a 30 mm diameter pipe rod. Two chains 800 mm long are attached to the latter with hooks, which, in turn, end with loops for the handles of ordinary shovels. Hooks and loops are twisted from 6 mm wire, and the latter have at least three turns (so as not to spoil the handle) and are stopped by one thick nail.

It is best to work together, from opposite sides, while mixing the solution and moving from one edge to the other. But you can do it alone - alternately on both sides. The chain, the length of which is adjustable with a hook, creates additional support. Thanks to the lever effect, it is much easier to use a shovel: you just need to press the handle and overturn the solution.

Device for mixing cement mortar (click to enlarge): 1 - rack (2 pcs.), 2 - M8 bolt (8 pcs.), 3 - sidewall (2 pcs.), 4 - bottom, 5 - shovel (2 pcs. ), 6 - rod (pipe), 7 - hook (2 pcs.), 8 - chain (2 pcs.), 9 - loop (2 pcs.), 10 - nails 3x40.

In order for the tin to be less deformed under the mass of the mortar, it is advisable to deepen the bottom into the ground or place a row of bricks or boards under the edges.

And the last thing: in an inverted form, my concrete mixer serves as a canopy for building materials.

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 ... >>

The full moon affects children's sleep 15.01.2017

Canadian scientists have found that the full moon affects the health of children. Including their sleep. Scientists came to this conclusion after a series of experiments.

It turned out that when the full moon comes, children and teenagers sleep much worse than at normal times. Sleep deprivation negatively affects overall health.

The most significant problems with falling asleep were experienced by children under the age of 11 years. Their sleep was also restless.

But adults are not subject to such a noticeable effect of the full moon.
