(54) МАШИНА ДЛЯ НАРЕЗАНИЯ ЩЕЛЕЙ(54) MACHINE FOR CUTTING

II

Изобретение относитс к землеройной технике, а более конкретно к дисковым фрезерным машинам, выполн ющим прорези в талом и мерзлом грунте.The invention relates to earthmoving machinery, and more specifically to disk milling machines that make slots in thawed and frozen ground.

Известна машина, включающа т гач с рамой, к которой шарнирно прикреплена подъемна рама с дисковой фрезой. В верхней части подъемной рамы на оси, установленной параллельно оси дисковой фрезы, укреплен вращающийс щнек, лопасти которого расположены между резцами (зубками ) дисковой фрезы, а в нижней части подъемной рамы смонтированы опорные лыжи .A machine is known that includes a tong with a frame, to which a lifting frame with a disk milling cutter is hinged. In the upper part of the lifting frame on an axis installed parallel to the axis of the disk cutter, a rotating pliers is fixed, the blades of which are located between the incisors (teeth) of the disk cutter, and supporting skis are mounted in the lower part of the lifting frame.

Недостатком фрезы вл етс то, что установка зачистного шнека параллельно оси дисковой фрезы из-за значительных биений фрезы приводит к заклиннванню шнека между зубками фрезы и, в конечном итоге к выходу зачистного устройства из стро .The disadvantage of the cutter is that the installation of the wiper screw parallel to the axis of the disk cutter due to the significant beating of the cutter leads to a wedge of the screw between the teeth of the cutter and, ultimately, to the release of the wiper.

Наиболее блнзкнм техннческим решением к предлагаемому вл етс ,машина, включающа т гач с рамой, дисковую фрезу с резцами, зачистной шнек, лопасти котс .рого проход т между резцами фрезы 2.The most blissful technical solution to the proposed is a machine that includes a machining gang with a frame, a disk milling cutter with chisels, a wiper blade, and a rotary blade running between the chisels of the milling cutter 2.

Недостатком машииы вл етс сниже-. нне ее эффективности из-за плохой очистки фрезы и неравномерного траНспортнровани материала.The disadvantage of machinii is reduced-. However, its effectiveness is due to poor cleaning of the cutter and uneven transportation of material.

Цель изобретени - повышеиНе эффективности путем улучшени очистки фрезы и транснортнровани материала.The purpose of the invention is to increase efficiency by improving the cleaning of the milling machine and trans-assortment of material.

Достигаетс цель тем, что в машине дл нарезани щелей, включающей т гач с рамой , дисковую фрезу с резцами, зачистной щнек, лопасти которого размещеНы между .резцами фрезы, машииа снабжена отгрузочным шнеком, установленным на кожухе, ко торым оснащен зачнстной шнек, при этом ло-. пасти зачистного шнека имеют гибкие элементы .The goal is achieved by the fact that in a slotting machine, including a cutting wheel with a frame, a disk milling cutter with chisels, a sweeping jaw, the blades of which are placed between the cutters, the machiia is equipped with lo- mouth sweep auger have flexible elements.

Claims

fS The machine contains a tacho with a frame 1, on which a disk milling cutter 2 driven by a transmission t of the tacci (not shown) is hinged. On frame I mounted hydraulic cylinders 3, which translate a milling cutter 2 from the transport position into working position and back, primer pickup 4 and stripping auger 5 along the generatrix of the screw blade of which are fixed panicles (brushes) 6. Wiper blades 5 are mounted in the casing 7. In the casing 7, perform a brush. which includes a part of the cutter disc with cutters 8. The blade of the wiper auger 5 is located between the incisors 8 of the disk milling cutter 2. The rotational drive of the wiper auger 5 is carried out, for example, by a chain drive 9 from the transducer. The rotation of the wiper 5 and the disk 2 are coordinated so that the blades of the screw 6 pass between the teeth 8 of the milling cutter like the turns of a worm, working in conjunction with a worm wheel — a disk milling cutter. Above the grinding auger and perpendicular to it, in the casing 7 there is mounted a discharge auger 10, the rotational drive of which is carried out from the motor II. A device for cutting gaps in the ground works as follows. Rotating, the cutter 2 teeth 8 cuts H makes the soil from the trench, where it is intercepted by a wiper auger 5, which raises the soil, and the shipping auger 10 transports it to the side of the trench. Subrafter 4 cleans the remaining primer, which also endures the milling cutter. The application of the invention provides a good cleaning of the cutter, and consequently, its external carrying capacity is improved and, in addition, the transportation of the soil becomes targeted. Claims slot cutting machine, including tach with frame, disk cutter with cutters, sweep auger, blades of which are placed between cutters of cutter, characterized in that, in order to increase efficiency by improving cutter cleaning and material transportation, the machine is equipped with a shipping screw mounted on the casing, which is equipped with a stripping auger, while the blades of the stripping auger have flexible elements.
