CZ307765B6 - Dosing device, in particular for dosing hydrogel, for planting forest growth, arranged as a superstructure on a creasing planting machine - Google Patents

Abstract

A dosing device, in particular for dosing hydrogel, for planting a forest growth as a superstructure on a creasing planting machine. It comprises a tank (1) with an opening for filling (2), a discharge opening (3) and a conduit (5) for conveying the dispensed material to the seedling. The inner space of the tank (1) contains a mixing and dosing device (4), connected to which is the conduit (5) for carrying the dispensed material. Mounted on the frame (10) of the grooving and planting machine is an operator cab (9), where the switch (6) for the mixing and dosing device (4) of the dispensed material is located above the floor, controlled by the operator.

Description

The invention relates to a metering device, in particular for metering of hydrogel and possible other admixtures, i.e. fertilizers, stabilizers and the like, in the artificial regeneration of forest stands by planting, as well as for establishing new stands in all areas affected by lack of moisture. The device forms a superstructure on a conventional creasing planter, allowing the dosing of a predetermined amount of ingredients to each plant separately.

BACKGROUND OF THE INVENTION

Artificial forest regeneration is currently carried out either manually, initially using hand hoes and planters, or mechanized using trenching machines or planting heads on hydraulic cranes of planters. Although the principle of the creasing planter has been known since the 1940s, its efficiency, ie up to 8000 seedlings per shift, has still not been surpassed.

Concerning the use of hydrogel in the restoration and establishment of stands, the application of hydrogel to soil is currently realized in three basic ways:

By soaking the root system in the prepared gel solution, the hydrogel in powder form is mixed in a certain proportion with the soil or substrate, which is then irrigated after planting, or the hydrogel in powder or mixture is poured directly into the prepared planting pit. Said methods are suitable for planting on smaller areas without full automation. There are also devices for the application of the hydrogel solution to the seedling, which are based on the principle of a planting stick supplemented with a hydrogel dispenser. However, these devices are also suitable only for individual planting.

None of the above mentioned solutions allows for highly efficient line planting with the addition of hydrogel and possible other impurities during the restoration and establishment of new large forest stands.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages largely eliminate a metering device, in particular a hydrogel, for planting forest stands arranged as a superstructure on a scoring planter equipped with an operator's cabin. The metering device comprises a tank provided with a filling and discharge opening and a pipeline for conveying the metering material. The essence of the invention is that the inner space of the tank is equipped with a mixing and dosing device to which a pipeline for conveying the dosing material is connected. This pipe is connected to the scoring planter structure between the rearwardly extended portions of the spreading blade. In the front of the operator's cab, the mixing and dosing device trigger switch is located above the floor.

From a material and structural point of view, it is advantageous if the hydrogel tank is made of plastic.

Furthermore, it is advantageous if the trigger switch of the mixing and dosing device is designed as a foot switch.

It is also preferred that the coupling between the trigger switch and the mixing and dosing device is mechanical or electrical.

DETAILED DESCRIPTION OF THE INVENTION

The metering device, in particular a hydrogel, for planting forest stands is arranged as a superstructure on a trench planting machine towed by a tractor in the present case. The metering device comprises a tank 1 provided with a top opening 2 and a bottom opening 3 and a conveying line 5. The tank 1 is equipped with a mixing and dosing device 4, to which said pipe 5 is connected for conveying the dosed material to the seedlings. This duct 5 terminates in the structure of the creasing planter between the rearwardly extended portions of the spreading coulter 7, behind which the spreading wheels 8 are arranged on the lifting mechanism. In the front part of the operator's cab 9 is located above its floor a trigger switch formed as a foot switch 6, which is here not shown in more detail by mechanical or electrical coupling with a mixing and dosing device 4. The hydrogel tank 1 is made of plastic.

When planting the forest, the spreading blade 7 of the trench planter creates a furrow in the soil into which the operator sitting in the cab 9 at certain intervals inserts the forest seedling, while simultaneously pushing each seedling in the foot furrow, a dose of hydrogel or other impurities, i.e. fertilizers, stabilizers, etc., is conveyed to the seedling root system via the conveying line 5. vegetation.
