The invention relates to a machine destined for the destruction of weeds and vine branches, which machine is composed of the framework having accessories placed thereon and a four stroke 7 Hp gasoline engine placed on 4 rubber bases via a screw stretching the belts for preventing jerks and allowing the rotation of the drum shaft. This drum shaft has 12 bases with 36 herb-cutting knives (3 knivesper base) inclinable on the left and right by 80 deg. so as not to impede the operation of the engine; this drum shaft is supported by bearings and its motion is ensured by 2 belts. A towing arm rising and lowering in dependence on the soil condition starts from the aforementioned framework bearing the accessories and ends with a pivoting tow bar towing a digging vehicle supplying to the inventeduprooting machine power. An operator's seat is placed on a double base of three tyres dispensing with jerks. Covers protect the bearings and the pulley of the shaft. The dimensions of the machine permitits access to smaller than 2 m spaces where tractor's access is impossible. Weeds covering 2500 m2 area may be destroyed in an hour. The drum shaft is 80 cm long, the framework (from one end to another) is 95 cm long, and the machine (along with thetowing digger) is 2,30 cm long, respectively. |
