Bushcutters

The invention relates to a vesicle clearing device which combines mechanical cutting of a vesicle and chemical treatment of stumps. The device comprises a vesicle cutting part, in connection with which a carrier handling device is built. The strain-5 treatment device brushes the stumps immediately after cutting with a chemical, whereby watering and strain growth is stopped for 2-3 years. The backhoe loader can be mounted on a power machine, for example a standard medium-sized or larger wheeled tractor, and does not require any 10 expensive special machines. The device is particularly well suited for clearing various roadsides.

Roadside times block visibility and thus endanger road safety. A creeper growing near the road increases the number of deer crashes. It has been found that deer 15 tends to cross the road from the safest possible place, i.e. at densities.

Snow throttling caused by vesicles also increases road maintenance costs, not just danger. In addition, a groomed ramp is more aesthetic than a ramp growing.

20 Among other things, various chemical and mechanical water control methods and equipment have been developed due to the above-mentioned factors. Among the chemical methods, mention should be made of air-spraying, which is currently completely banned. Foliage spraying is also used, but it will also be abandoned due to the environmental damage of the 25 countries. Foliage spraying is difficult to control as toxic mist may spread some distance with the wind.

Various mechanical devices have been used for clearing plows, but they have the disadvantage of strong watering, especially on willow and alder. Mere mechanical control in wicker areas must be carried out annually. In addition, mechanical ./ ..

2 66107 control is more expensive than chemical control.

FI - patent publications 4.9354 »52508 and 59691 disclose clearing equipment attached to a vehicle, e.g. a tractor. The disadvantage, however, is that they lack chemical treatment after cleavage.

FI - Publication 49103, FI - Patent publications 52648 and 53649 disclose combinations of clearing saws in which a venom sprayer is arranged in connection with 40 clearing saws for the chemical treatment of stumps. However, as in the embodiment of the present invention, they do not have a rotating roller which foams the ends of the bases. In addition, the devices disclosed in the publications are hand-held and cannot be compared in efficiency to a nailing device to be connected to a vehicle according to the invention.

It is an object of the present invention to overcome the disadvantages of the above methods and apparatus and to provide a clearing device which combines both a chemical and a hydraulic clearing device and thus to produce a clearing device which is considerably more efficient, less expensive, easier to use and more environmentally friendly than hitherto known devices.

The characteristic features of the invention are given in the appended claims.

The invention will now be described in more detail with reference to the accompanying drawing 1, which shows a chemical carrier processing device mounted on the cutting head of a clearing device.

The operation of the device according to the invention is essentially 60 as follows:

The clearing device 1 with rotating blades (not shown) mechanically cuts the blade, after which the stumps 3 661 07 are chemically treated with a strainer 2. Hormone solution in a separate container, e.g. MCPA solution 65 (trademark) mixed with a blowing agent, e.g. 2 (trademark), is pumped along the transfer tube 3 into the nozzle tube 4 · In the nozzle tube 4, the solution is foamed by the branch tube 5 with compressed air. Through the nozzle tube 4, the foam 6 is discharged into the housing 8 on the roll 7. When the housing 8 is full of foam, the photocell 9 stops the pump (not shown), and when the foam surface has settled, the photocell 9 in the housing 8 restarts the pump. The hydraulic motor 10 rotates the roll 7, and at the front of the housing 8 there is a scraper 11 which keeps the foam even throughout the length of the roll 7 75. As the roll 7 rotates at a constant speed, the foam remains attached to the roll 7. When the roller 7 touches the carrier, foam remains from the roller 7. The foam only stays in the stems and crops and does not spill into the soil at all. The size-80 formed by the clearing device 1 and the stump handling device 2 is connected to the power unit by means of hydraulic booms and hydraulic hoses (only the connection point is shown on the left side of the figure). The arrow indicates the direction of the picture power of advance of the machine.

The above-described device, in which a mechanical cutting and chemical carrier handling device attached to the power machine-85 performs clearing and post-treatment of the coulter as the power machine travels, e.g., along the roadside, provides numerous advantages over current methods and devices. These include e.g. the following: 90 Combining mechanical cutting and chemical treatment of strains saves about $ 40 in clearing costs. In addition, watering and growth are stopped for 2-3 years.

Based on experiments, the hormone solution when foamed is more effective than as a liquid.

K

95 As the foam liquefies, it is better absorbed into the carrier, as the soap solution reduces the surface tension of the liquid. When the chemical treatment is done with foam, no pesticide is poured into the soil, so the device does not harm the environment.

100 The clearing machine is efficient, inexpensive and easy to use, and is suitable for use on all types of roads.

The device can be mounted on different types of power engines, e.g. a standard medium-sized or larger wheeled tractor. It does not require any expensive special machines. The device cat-105 covers and chemically treats vegetation with a diameter of less than 10 cm. The device is easy to attach to the power unit with quick-release or bolts and hydraulic hoses with quick-connect fittings.

The device can also be used on road signs 110 thanks to the hydraulic folding extension booms.

The woodcut clearing device is also suitable for clearing telephone and electricity lines, as well as small wood and woodcock clearing in forestry work.
