Potatoes - one of the most popularcrops that are grown not only in our country but also in many countries of Eastern Europe. Over three hundred years of the history of potato cultivation created agronomic technology with which tried to facilitate the cultivation of culture and increase its productivity. If an industrial scale potato cultivation hilling plants today use tractors with interchangeable nozzles cultivators, the home gardens can be used hiller made with their own hands for motoblock.
Hillers is the second most important tool after plow and winch. Use it to cut the first furrow for planting, and later fill them with the planting material.
Through the aisle exactly hiller potato planted rows can be seen as a tool of the wings rather quickly pour soil into the hole with tubers
On sale you can find several options for models of this tool.
This is the easiest type of instrument, which hasfixed widths. The design consists of two connected and slightly spaced fixed wing. Since the tool motionless wings, you can not adjust the width of the capture, hiller adjusting the width of the rows. Therefore, when working with a tool adapted to the aisle hiller capabilities, and not vice versa. Traditionally, manufacturers produce products with a width of 25-30 cm, which is also not the most convenient option, because potato production technology provides a width between rows 50-60 cm.
These tools are designed to work with the cultivators, that power does not exceed 3.5 hp, and the total weight of the unit is 25-30 kg
Design feature listernyh Hillers is also the presence of thin struts that prevent overload cultivators hiller with burial in the dense layers of the soil.
Some models listernyh Hillers are streamlined, which is more preferable, because when dealing with such a tool and less everted issushivaetsya soil.
Such tools are more convenient to work,as equipped with adjustment mechanism, with which you can change the position of the wings. This allows you to adjust the instrument at different row spacing.
Such Hillers are designed to work with a more powerful engine with tillers of 4, 0 hp or more, weighing more than 30 kg
A significant disadvantage of such constructionsis their large power consumption. The reason for this is that during operation of the tool in the soil the wings push side of which after passing though flaking back into the furrow. As a result, back and arms will get tired, and some of the engine power expended in useless work. But despite this, they are among the most popular models among the majority of farmers.
Disc Hillers are an order of magnitude more expensive than their traditional counterparts, but also the efficiency of such instruments at times more
The main advantages of disk Hillers are:
- The successful combination of two-wheel tractor with yourself tool. Using disk hiller, with decreasingcultivators speed increases its capacity. This not only increases the efficiency of cultivation, but also positively affects the work of the unit.
- Ease of use. To use this tool you need to make a minimum of effort: he propels itself forward, without requiring an additional push from behind.
- Versatility. With this tool, you can produce ridging after the planting of tubers, and in the period of active growth of the aerial parts of plants.
Choosing among the variety of assortment,it is desirable to give preference to models made of stainless steel, equipped with anti-friction bearings (rather than bushings sliding), with a large diameter and disc thickness.
The principle of the instrument is to workspecial props, under the influence of which the first is crushed soil and combed out weeds, and after the loose soil spud beds
Such Hillers intended for arrangementtillers and cultivators, who have two forward gears. This is necessary in order to transfer to the second power with an increase to 180 rev / min., With the tool can not only loosen, but also to transfer in a bed of soil between rows.
As can be seen, Hillers are a fairly simple structure. In fact, to make their own hands hiller for motoblock, no big deal.
To create a traditional unregulated hiller necessary pattern of metal 2 mm thick cut halves of the product
These halves should be bent to matchradii and then boiled for 2-3 passes. Welds should be treated and selectively podvarit grinder and re-clean if necessary. The result should be a perfect smooth layer of metal.
Tool as wings are cut from a 2 mm thick metal and connected to the same principle
The result is such a design should get. For clarity, the thickness of the elements and contains all dimensions of the tool base
For the manufacture of the tool you need to choose the type of wings. Discs plowshares or blades, are steel sheets 1.5-2 mm thick, having a bent lower edge.
An important condition: the disks must be strictly symmetrical. Otherwise, the design is the "lead" in the direction that will significantly complicate the work.
At arrangement design can be used plowshares, taken from the end of its term of sowing.
Felling ploughshare set at an angle, keeping the distance between the lower points of the corresponding wheel track width equal to the width between rows
Elements joined together usingby bolting or welding. The discs are connected by means of adjustable adapters. In addition to the drives, the basic elements of the tool are: T-leash, screw turnbuckles and racks. Lanyards necessary for regulation along the vertical axis of rotation disks. For walk-behind tractor tool is secured with the help of a beam with the wings.
In the manufacture and assembly of components on the basisDrawing is important to provide the ratio of the size and design of attachment. There are two variants of the tool manufacturing: fixed or variable width of the wings. In the second method arrangement distance between the discs can be varied by symmetrical permutations of racks.
Key elements of the assembly: 1 - processed row 2 - Disc 3 - fist 4 - T-shaped bracket 5 - Stand 6 - a steel scraper, 7 - axle, 8 - locking bolt 9 - arm-gryadil
To facilitate the work with the tool necessary to provide arrangement of sliding bearings. Installing bearings rather than the sliding sleeve can improve the reliability of the product.
During construction assembly for mountingTillers tool to involve the coupling bracket without gryadilya. To this end, the bracket is secured using the retainer bolts and flat washers leash hiller. The stopper is inserted into the square tubing and tightly pressed against its outer surface.
Sam hitch bracket with screws turn, and the lead is placed along the longitudinal axis of the motor cultivator
The unit is ready for operation. Working on the first gear, by reducing the forward speed can be increased traction motor cultivator. If during earthing up the wheels are slipping, to pair them.
