Description

Изобретение относится к бурению горных пород, а именно к устройствам для очистки шнеков.The invention relates to rock drilling, and in particular to devices for cleaning screws.

Известно устройство для очистки шнеков, включающее очистительный элемент [1 ] .A device for cleaning screws, including a cleaning element [1].

Недостатком этого устройства является то, что для очистки шнека необходимо его вращение, приводящее К осыпанию буровой мелочи в скважину и снижению эффективности бурения.The disadvantage of this device is that for cleaning the auger it is necessary to rotate it, leading to the shedding of drill fines into the well and a decrease in drilling efficiency.

Наиболее близким к изобретению из известных техничесжих решений является устройство для очистки шнека, включающее барабан с очистньми Элементами и привод [2].Closest to the invention of the known technical solutions is a device for cleaning a screw, including a drum with cleaning elements and a drive [2].

' Недостатком этого устройства является то, что поджатие винтами очистных элементов к шнеку производится вручную.'The disadvantage of this device is that the screws tighten the cleaning elements to the screw manually.

Цель изобретения - автоматизация поджатия очистных элементов к шнеку.The purpose of the invention is the automation of the preload of the treatment elements to the screw.

Цель достигается тем, что барабан снабжен коромыслами, одни плечи кото-25 рых подпружинены и имеют грузы, а на других закреплены очистные элементы.The goal is achieved by the fact that the drum is equipped with rocker arms, some shoulders of which are 25 spring-loaded and have loads, while cleaning elements are fixed on others.

На чертеже изображено устройство для очистки шнеков, общий вид.The drawing shows a device for cleaning screws, General view.

Устройство содержит барабан 1, ко-?30 ромысла 2 с очистными элементами 3, грузами 4 и пружинами 5 и привод 6.The device contains a drum 1, number 30 of the beam 2 with cleaning elements 3, weights 4 and springs 5 and a drive 6.

Устройство работает следующим образом.The device operates as follows.

При подъеме шнека 7 из скважины барабан 1 приводом. 6 приводится во вращение. Грузы 4, преодолевая сопротивление пружин 5, отходят от оси вращения под действием центробежных сил, и очистные элементы 3 автоматически поджимаются к шнеку 7. При этом усилие Поджатия очистных элементов к шнеку регулируется скоростью вращения барабана 1.When lifting the screw 7 from the well, the drum 1 is driven. 6 is driven into rotation. The weights 4, overcoming the resistance of the springs 5, move away from the axis of rotation under the action of centrifugal forces, and the cleaning elements 3 are automatically pressed to the screw 7. In this case, the force of pressing the cleaning elements to the screw is regulated by the speed of rotation of the drum 1.

Claims

The invention relates to the drilling of rocks, in particular to screw cleaning devices. A device for cleaning augers, including a cleaning element 1, is known. A disadvantage of this device is that it requires rotation to clean the auger: leading to the shedding of fines into the well and decrease in drilling efficiency. The closest to the invention of the known technical solutions is a screw cleaning device, including a drum with cleaning elements and a drive 2. The disadvantage of this device is that the screws of the cleaning elements are pressed manually to the screw. The purpose of the invention is to automate the pressing of cleaning elements to the auger. The goal is achieved by the fact that the drum is equipped with rocker arms, one shoulders of which are spring-loaded and have weights, while others are attached to cleaning elements. The drawing shows a device for cleaning screws, a general view. The device contains a drum 1, romady with cleaning elements 3, weights 4 and springs 5 and a drive 6. The device operates as follows. When podyshenes 7 from the bore drum 1 driven. 6 is rotated. The weights 4, overcoming the resistance of the springs 5, move away from the axis of rotation under the action of centrifugal forces, and the cleaning elements 3 are automatically pressed against the screw 7. At this force, the pressing of the cleaning elements to the screw is controlled by the speed of rotation of the drum 1. The invention of the device for cleaning screws , including a drum with cleaning elements and a drive, which is different from the fact that, in order to automate the pressing of cleaning elements to the auger, the drum is equipped with rocker arms, one shoulders of which are spring-loaded and have weights, and on others fixed s treatment .elementy.
