Modern models of knapsack sprayers are characterized by reliability, efficiency and high ergonomics. Such an apparatus can be considered not only as a garden assistant in protecting plants from insects. If necessary, some models can be used as a tool for paintwork. Compared to other types of sprayers, handheld garden sprayers are easier to handle and require less maintenance. True, you cannot serve large areas with such a device, so there is no need to talk about wide versatility either.
Sprayer device
The basic structure of such units provides for the presence of three mandatory components. This is a container that contains a chemical or other working fluid, a pumping mechanism and the spray channel itself. As for the container, that is, the tank, it can have a different volume and is made from a wide range of materials. Polypropylene and its modifications are considered the most practical solution. The material is lightweight, durable and does not affect the contents. The knapsack sprayer also contains one or another liquid supply system. It could bepump mechanism, and a drive motor system and even a battery. Regardless of the tank and pumping system, almost all sprayer models have similar mixture release devices, i.e. nozzles.
Key Features
Models are quite diverse, each parameter is of great importance in the process. For example, the tank capacity of modern backpack sprayers varies on average from 5 to 25 liters. On the one hand, it may seem advantageous to purchase the most capacious model, since it will have to be filled less often, but, on the other hand, it will be heavier. Do not forget that during operation, the user's shoulders will act as a support for the unit. The mass is from 7 to 10 kg, which should also be taken into account. As the practice of those who use a backpack sprayer shows, 12 liters is quite enough to work on a medium-sized private plot. But there is another important characteristic - it is performance. It is determined by the volume of fluid released in 1 minute. This indicator depends on the type of drive mechanism, but in the simplest models it varies from 0.7 to 1 l/m.
Varieties of models
As mentioned above, the fundamental difference between knapsack sprayers is the type of mechanism that provides spraying. There are three different approaches to implement this part. The basic and traditional is the pump-action manual mechanism. Such a unit is driven by pumping provided by muscle effort. Help relieve yourself of physical exhaustionbackpack powered sprayer powered by gasoline fuel. Such models have the highest performance and a decent spray radius. The advantages are attractive, but you will have to pay for them with exhaust from fuel processing, noise with vibrations and the high cost of the sprayer itself. And this is not to mention the cost of refueling with gasoline, although such devices consume little. An alternative solution would be a battery powered sprayer. It also benefits from good performance, but, unlike the gasoline model, it is environmentally friendly, quiet and weighs less. But its working time is limited by the capacity of the battery, so you should initially calculate the amount of one-time consumption if there is no access to the mains on site.
Additional features
In terms of the spray system itself, manufacturers do not indulge in new technologies, but this is understandable. The existing principle of supplying liquid through nozzles with the possibility of adjustment is optimal and additional optional difficulties can only be harmful. Therefore, the main emphasis is on improving ergonomics. Many manufacturers are improving the design of the back of the device, providing it with special linings. Also, for ease of installation on a horizontal flat plane, the knapsack sprayer is equipped with a special stand that can be removed, lightening the weight. Some models optionally include additional booms that extend the spray channel.
Reviews of the Beetle models
It can be said that the basic solution used by most Russian summer residents and gardeners. Products of this brand attracts attention with a simple design, affordable price tag and unpretentiousness in care. An example is the modification of the Cicle OG-112, which has a volume of 12 liters. Users of this sprayer note its reliability and modest weight, due to which acute physical fatigue is not observed even after prolonged use of the device. In addition, the Zhuk knapsack sprayer is provided with a filtration system that prevents solid inclusions from penetrating into the working channel. This addition is important both in terms of the reliability of the device, and in terms of maintaining the he alth of the vegetation. The owners of Zhuk knapsack sprayers also note the convenience of the telescopic rod, which is easily adjustable, adapting to the needs of specific conditions and tasks.
Reviews of Gardena models
For ordinary gardeners, the manufacturer produces a line of sprayers "Comfort". It presents models with different displacements, but most of them are based on a pump-action mixture supply system. From the user's point of view, an important difference between these products is their manufacturability. Gardena has always been famous for high-quality constructions and careful selection of materials, therefore, polypropylene sprayers do not cause any complaints about strength and durability. More interest in many is precisely the technological development of models. So, even a pump-action knapsackthe 5 l sprayer is equipped with a filling indicator, which is convenient when working with sensitive plants. Of course, there are larger devices in the Gardena line, designed to service public areas, gardens and park areas.
Reviews about Solo models
Modification 417 in the Solo line is a sprayer equipped with a 12 V lead-gel battery. According to users, this model is convenient when working with greenhouse plants. The fact is that, unlike gasoline devices, battery models can, in principle, be used indoors. And if it is impractical to use a pump-action device for maintenance of large areas, then a battery-operated handheld backpack sprayer is quite suitable for such tasks. What's more, the 417 version stands out from competitive battery models in that one charge is enough to release a large amount of chemical - on average, users say about 180 liters.
Reviews of ECHO models
The SHR-170SI model deserves attention in the line of this manufacturer. It should be noted right away that this device is not designed for an ordinary private gardener or summer resident, but for owners of large areas with green spaces. This is a gasoline unit with a 0.6 kW 2-stroke engine. Also, the owners of the model note a capacious tank of 17 liters. However, this layout will not be convenient for everyone - you need to understand that both the engine and the tank cause considerable weight.designs. But in terms of performance, the knapsack sprayer in this version is one of the best representatives of its class. According to experienced users, the model is productive, functional and reliable. If you need to spray large areas, then this option will be optimal. However, it is important to take into account another nuance: it will not be possible to serve greenhouses and greenhouse facilities with this model due to harmful emissions.
How to choose the right option?
First of all, it is worth deciding on the requirements for the production volume of the chemical. For a small area, 5-liter devices are quite suitable, which, if possible, can be retrofitted with regulators and flow control devices. Plots of medium size can be served with 10-12-liter units. It can be either a domestic unit from the Zhuk family of a pump-action type, or a representative of foreign garden equipment based on the battery pumping principle. If the task is to work in the fields or large areas, then a knapsack sprayer with motor traction on gasoline is suitable. Such models, of course, have the negative aspects of operation and not the best ergonomics, but they have no equal in terms of performance.
Conclusion
The presence of a garden sprayer on the farm is necessary for any caring and responsible summer resident. This tool will effectively maintain the vegetation in a he althy state, timely eliminate and prevent disease processes and the spread of harmful insects. Compared to otherschemical spraying devices, the backpack sprayer features convenient operation, simple liquid supply system and lightweight structure. At the same time, there are different modifications with certain indicators of performance, functionality and reliability. Although the basic design principles of these horticultural products have not changed for many years, individual technological improvements are increasingly appearing in recent versions. This includes the introduction of a chemical flow sensor, and effective filtration systems, as well as structural devices that contribute to a more comfortable handling of the units.
