(54) РАБОЧИЙ ОРГАН ПЛУЖНОГО КАНАЛОКОПАТЕЛЯ(54) WORKING BODY OF THE PLUNNY DUCKER

II

Изобретение относитс к землеройным , а более конкретно к плужным каналокопател м.The invention relates to earthmoving, and more specifically to plow canal-smokers.

Известен плужный каналокопатель, включающий раму и отвал с режущими ножами 1 .Known plow kanalokopatel, including the frame and blade with cutting knives 1.

Известный рабочий орган требует больших т говых усилий.Known working body requires large traction efforts.

Известен также рабочий орган плужного каналокопател , включающего отвалы и ножи, к режущим кромкам которых подаетс сжатый газ. При этом частично обеспечиваетс снижение потребного т гового усили 2.Also known is the working body of a plow canal-blade, including blades and knives, to which cutting edges compressed gas is supplied. In this case, a reduction in the required tractive effort 2 is partially ensured.

Однако имеют место потери на трение опорной лыжи о грунт.However, there are friction losses of the supporting ski on the ground.

Цель изобретени - снижение потребного т гового усили .:The purpose of the invention is to reduce the required tractive effort.

Достигаетс это тем, что в рабочем органе плужного каналокопател , включающем отвал с режущими ножами и опорную лыжу, последн сверху снабжена газовым коллектором, соединенным с источником сжатого газа.This is achieved by the fact that in the working body of the plow canal-blade, which includes a blade with cutting blades and a supporting ski, the latter is equipped with a gas collector connected to a source of compressed gas.

а снизу - опорной плитой с пазами, при этом коллектор и опорна плита соединены посредством крепежных элементов, в которых выполнены каналы дл прохода газа к пазам, которые выполнены относительно горизонтальной плоскости под углом .and at the bottom - a base plate with grooves, while the collector and the base plate are connected by means of fasteners in which channels for the passage of gas to the grooves, which are made relative to the horizontal plane at an angle, are provided.

Каналокопатель включает отвальнуй поверхность скольжени , центральный 2 и боковые 3 режущие ножи, раму 4, опорную ль1жу 5 с рычагами 6, The digger includes a slide-out surface, central 2 and side 3 cutting knives, frame 4, support 5 with levers 6,

15 установленную на тыльной стороне поЧ верхностей скольжени 1 на уровне центрального ножа 1. На опорной лыже 5 сверху смонтирован газовый коллектор 7 с трубопроводом сжатого 15 mounted on the rear side of the glide surfaces of slip 1 at the level of the central knife 1. On the supporting ski 5, a gas collector 7 is mounted on top with a compressed pipeline

Claims

20 gas 8 from a source, such as a compressor installed on tons of gas (not shown). Bolts 9 pass through the gas collector 7, under the knife, sunk under the knife, with secret heads and enveloping the support plate 10 installed below the support ski 5, and at the top with nuts 11 through the gaskets 12 abut against the outer surface of the collector 7. Along the vertical axis of the bolts 9, channels 13 are provided with plugs 14 in the upper part and connected by upper radial holes 15 with the internal capacity of the gas collector 7, and lower 16 near the blind heads of the bolts with slots 17 made below and oriented to the side, against the canalocopathlon movement. The grooves 17 in the base plate 10 with respect to the horizontal are made at an angle of cl 30 to provide a release of gas lubricant to the surface of the skull along the tangent. A support ski 5 is mounted on the canalbogger with the help of levers 6 and a screw 18, which also controls the position of the ski relative to the central knife 2. The canalminator operates as follows. The canal-digger is mounted with the help of frame 4 on the tank trailer (not shown). When lowering it to the required depth with a screw 18, the supporting ski 5 is installed on the same level as the central cutting knife 2. When the canal-blade has just moved, the heel of the sliding surface 1 cuts out the ground and forms the required cross-section, the lower base of which moves with great pressure on the ground. Unt support ski. To reduce the resistance to movement of the supporting ski 5, compressed gas is supplied from the compressor through the pipe 8 into the gas collector 7. From there, the gas flows through channels 14-16 into the slots 17, and then goes to the outer sliding surface of the support plate 10, while ensuring its movement gas lubricating layer. This reduces the overall traction resistance of the canal-smoker, especially when trenching in wet and sticky soils. On the base plate 10 (FIG. 3), the bolts 9 are made in two rows and in a checkerboard pattern, which provides almost complete lubrication of the sliding surface of the base plate 5. This leads to a decrease in the thrust force of the canal-cokings, which reduces the energy intensity of the process. The head of the bolts 9 has recesses 19 for a four-sided wrench for mounting the bolts when screwing in the nuts 1I. The use of the invention provides a reduction in traction effort, which allows the passage of ditches at a higher operating speed. Claim 1 The working body of a plow canal-blade, which includes a blade with cutting knives and a supporting ski, is characterized in that, in order to reduce the required pulling force, the upper side is equipped with a gas collector and a source of compressed gas connected to it, at the same time, the collector and the support plate are connected by means of fasteners in which channels for the passage of gas to the grooves are made, 2. The body is pop.1, which is also distinguished by the fact that the grooves are made relative to the horizontal plane at an angle ct; 5 30.
