Description

Oskkovnoy machine, dehumidifying the development of soils without prior loosening, is a sdnok; .vi; opy; -; tale2op, performing a large PURE of mechanic: :: e x earth; ;;;; :: CT.

Until now there is no effect:.;: -;; ze:.: leroy machines for work c. frozen and rocky ground.

The applied development methods of tight-walled grids with a preliminary warming of soils from the swamp, with the otinancim zle1 :: tropogrev. bonfires or loosening by pile driving equipment with a klkk-baba or a clip-hammer of a small piercing system, which is labor-intensive and greatly increases the cost of earthworks.

To organize work in frozen soils without explosions and loosening with a performance close to the Pr: cell, most of the conditions, it is proposed to use a single-bucket excavator with a bucket equipped with vibrating teeth, and with the ycTairoBicoii compressor for compressed air supply to the tooth m bucket.

The special feature of the proposed excanatos sostomt is that the compress installation for supplying compressed air Y. the teeth of the hammer are connected to them by a flexible hose suspended from the boom. One end of this hose is connected through the hollow axis to the compresor installation, and the other end is connected to the channels in the bucket, and then to the tooth:,;.

FIG. 1 shows a side view of an excavator with a bucket equipped with vibrating teeth; in fig. 2 - side view of the bucket; ka fig. 3- bucket rear view; in fig. The 4-vibrating tooth is xcive in section along aa-a in fig. 3

Buckets with vibrating teeth can be installed on the bottom excavator of any design.

The power of the group of vibrating teeth (three or four, depending on the capacity of the cowl) installed in the front front wall of the KOBHia is made by means of a hose 3 and channels 4 and 5 in the bucket.

In order to reduce the impact of the pump on the TaiOHiero pipe 3 during the operation of the excavator, the wheel is mounted on the BLS-drum 6, which automatically adjusts the glang length of the valve during the working cycle. lifting and; and twisting the H- and the handle is amazed, and due to the constant tension, provides one with a counter-load 7. 1 stores a new one close to the molar type. The supply of air from the compressor to the boosban via axis 5 ensures normal and safe spun ptlang, the o.UiH end of which enters the drum.

In the application of gynecals, only the front

KOBFia teeth are made in the form of wedges, the symmetry of which is Kovnadat with the metric of a recurring frontal wall of the bucket.

For the movement of a group of hammers, which vibrate the teeth of a m, 11e obhog g: they have a combusor from a producer of 4-5 liters per minute at a pressure of 5 6 atm.

C. Each 1; of pneumatic hammers consists of a barrel 10, in which the SM moves reciprocally under the effect of augmented air: nick //, gold 12 and spool box 13, connect with STBO.POM at P1. link 14, and so; ke launcher, smontproBaiinoro in link i4, acting automatically.

npi; cutting the soil cues the bucket tooth under the action of the axial load is mixed back in the box 15 and the tail part is moved by the hammer, which mounts the free fit in the nest 16, but towards the KOBHja unit. At this time, the support springs / 7 are compressed and the starting valve 18 opens, through which the compressed air of the foot moves into the annular chamber 19 located around the spool box, and alternates between one half-sided cylinder and the other. A drummer 11 moving under the action of compressed air hits the shank of the bucket tooth. The exhaust of air from cy.1I1-; d, the frame is carried out through the holes located on the outer side of the front wall of the bucket with a downward slope, which eliminates the possibility of their clogging with soil.

At the end of the cutting of the soil, the load on the tooth disappears when the load is 17; ozBra dg: Ute hammer to its original position, at which the starting valve 18 knot is closed by the action of the spring 20 and the hammer turns off.

The bucket tooth is secured with the aid of checks 21, which allow the tooth to mix in the axial direction by an amount necessary for the working stroke and automatic shutdown of the hammer. In addition, the tooth is located in a rectangular slot, in the front wall of the bucket, which holds it from enemy gear and unloads the check 21.

To absorb the energy of individual idle shocks, shock absorbers are provided, which are located in the absorbers, absorbing the impact energy, and protect those seeking a check from damage. .

The croo-me of the vibrating teeth is set by the usual non-suspended teeth 22, shorter, intended for cutting small tubercles, and not chipped.

Subject invention

Claims (2)

1. A single-bucket excavator with a bucket supplied with vibrating teeth, and an electronic gearbox for supplying pressurized air to the teeth of a bucket mounted on the rotary frame of the excavator, and with the fact that supplying air to the teeth of the bucket is connected to the teeth of the bucket by means of a flexible hose freely suspended from the boom, one end of which, for the purpose of 1) controlling the sag of the hose, is fixed on the rim of the rotary drum equipped with a counterweight and connected via a hollow axis to the compressor The other end is connected to channels in the bucket connected to the teeth of the bucket. 2. An excavator according to claim 1, characterized in that. that the teeth of the bucket are provided with shock absorbers for the Cl of the shock at idle and their own shank and sit in a guide that protects them from moving. -: -. -Afb 90798
