If you want to have a good harvest, take care of the garden. Autumn is a busy time for such events. Branches are completely cut off, tops are dug out, various plant waste is removed. Once it was all burned at the stake. At the present time, when there is a struggle for the environment all over the world, and making fires even on private plots threatens with administrative responsibility, one should think about another method of disposal. An irreplaceable assistant in this matter will be a garden shredder (crusher) for a summer residence.
Description and purpose
This is a highly specialized equipment created for the processing of plant waste. For example, such as grass, cut or cut branches of shrubs and trees, fruits, small pieces of processed wood, sticks, chips, etc. And in the end:
- you get excellent fertilizer in the form of mulch or excellent filling for the compost pit;
- keep your area clean;
- save money that you would have spent on garbage collection and the purchase of fertilizers.
Shredders are often called foreign words - chippers or shredders. Their structure is quite simple. They have a housing made of plastic, steel, or a combination thereof, it all depends on the class of the unit.
Plastic units are the lightest . They are comfortable and easy to move around the garden area. Steel body versions are usually used for stationary applications, regardless of the presence of wheels for movement, since they are heavy.
An important detail is the wheels . If they are too narrow, then the heavy shredder will be difficult to move around the site, it will get bogged down in the ground. Therefore, the wider the outside of the wheel, the better.
A material receiver or hopper (loading box) is located on top of the body. With it, you can load debris to the cutterhead . It can be a fixed extension of the body, or it can move, changing the degree of inclination.
The crushed material is discharged through a special bell or hopper . It can be straight or located at a certain angle (it can be rearranged). This makes it possible to more conveniently collect the crushed material.
Varieties
Taking into account the power, weight and diameter of branches for processing, chippers can be symbolically divided into 3 types: household, semi-professional and professional.
By the type of engine used
Garden shredders can be electric or gasoline, some professional modifications are equipped with diesel engines.
Electrical are mains powered, therefore their use is determined by the size of the cable. For the most part, these are samples of small mass with a power of up to 1.5 kW. They are capable of crushing branches with a diameter of 20-30 mm. If you have a small plot (10-15 acres) and not a lot of grass, foliage and natural waste that needs to be recycled, this version is fine.
There are also more powerful electrical units that are capable of chopping branches up to 50-60 mm . Their power can reach 3, 8-4 kW, but for their operation they must be connected to a 3-phase network, therefore, these modifications are difficult to call a household version for a wide range of users.
Note: the most simple household models are designed for manual (mechanical) cutting of grass on a special platform using a knife, which is integrated with the body and can be raised and lowered above it. They can be used to make feed from grass cuttings, nettles for animals and birds such as chickens.
Gasoline function without being connected to the mains. The power of these units depends on the application.
For household samples, this figure is 5-8 liters. with. For professional modifications, the power can reach up to 14 liters. with. The diameter of the shredded branches is 10 cm (for domestic ones - 5-8 cm). In small areas with several fruit trees, this technique is not justified.
On the bulk of gasoline units, in order to provide the necessary torque on the cutting mechanism, 4-stroke engines with a horizontal crankshaft are practiced. Manufacturers install third-party motors on the shredders. On modifications of the budget segment, as a rule, motors from Chinese companies are used.
The main advantage of gasoline samples is maneuverability . Professional units are installed as a trailer to a walk-behind tractor, car or tractor. On separate devices, it is possible to operate from the power take-off shaft (PTO) of the tractor. For the sphere of housing and communal services, the fundamental parameter is the noise of the engine, since it is often brought to work in parks and squares, where the loud operation of the engine will be inappropriate.
Diesel motors, as a rule, are installed on professional equipment. These drives can operate for a long time without interruptions, they perfectly keep low revs, they do not need a complex ignition system.
Such samples will fit in organizations engaged in the improvement of significant territories, squares, parks, as well as in industrial enterprises and forestry enterprises. But at home, such shredders, in essence, do not find use, simply because of their high price, large size and difficulty with independent movement across the site.
However, the type of power plant does not always become a determining condition in terms of the "professionalism" of the unit . So, you can buy a small-sized household model with a gasoline 2-stroke engine, along with this, there are also stationary or mobile units of the pro class, equipped with a powerful 3-phase electric motor.
By type of cutting mechanism
An important criterion that has a great influence on the choice of a garden shredder is the type of cutting mechanism. The type of garbage that the installation is capable of processing depends on it.
Knife system - the cutting mechanism includes circular knives . It is suitable for crushing fresh branches with a diameter of 1-2 cm, leaves and raw grass. When using the knife system to chop hard woody branches, the cutting tool will quickly become unusable and the knives will need to be replaced.
On a note! The main parts of the milling system are the gear (cutter) and the cutting blade. Rotating, the gear grips the branch between the cutting insert and itself. During use, the distance between the plate and the cutter can change - the device only begins to leave scars on the branches, but does not split them. This means that the clearance needs to be corrected.
Milling (gear) mechanism - contains in its structure a large gear rotating on a shaft, and a gearbox that reduces the speed . The cutter speed is low, but a huge force is applied to the gear, which makes it possible to split and chop large dry branches. The output is coarse chips, which are suitable for surface soil coverage. The gear mechanism is not suitable for chopping green grass, soft debris will wind on the gear shaft, and the unit will eventually clog.
Universal cutting mechanism - copes with both branches and leaves . These shredders are equipped with a milling-turbine crushing system, it has the shape of a funnel with sharp blades that process soft material, the branches are pressed against the stop and crushed according to the pattern of the milling system. In some modifications, the universal system is performed differently. Inside the shredder, 2 separate channels are formed with two funnels, one for branches, the other for soft organics. Such a design implies a serious complication of the design, which affects the cost of the unit. Individual channels are present in the bulk of professional designs.
Fishing line - the cutting mechanism contains in its structure a spool with a fishing line similar to a grass trimmer; a garbage bag is installed under it . Samples with a similar design belong to electric ones and are capable of crushing leaves and grass exclusively.
