Изобретение откоситс к области отбора проб, и в частности, к устройствам дл отбора монолитов мерзлых грунтов.The invention tends to the sampling area, and in particular, to devices for sampling frozen soil monoliths.
Известно устройство дл отбора монолитов грунтов, содержащее корпус, многорезцовый рабочий орган и керноприемную камеру l .A device for sampling monoliths of soils is known, comprising a body, a multi-cutter tool and a core receiver l.
Недостатком устройства вл етс плохое качество отбираемого монолита грунта.The drawback of the device is the poor quality of the soil monolith being sampled.
Наиболее близким к изобретению по технической сущности вл етс устройство дл отбора монолитов мерзлых грунтов , содержеидее корпус, многорезцовый рабочий орган и керноприемную камеру с подпружиненным скалыватeлeм 2J . .The closest to the invention to the technical essence is a device for the selection of monoliths of frozen soils, a housing with a lower body, a multi-cutter body and a core receiver chamber with a spring-loaded cleaver 2J. .
В этом устройстве многорезцовый рабочий орган выполнен в виде расположенных по периметру керноприемной камеры шнеков с резцами в нижней части , а скалыватель - в виде вилки.In this device, the multi-tool body is made in the form of augers located along the perimeter of the core-pickup chamber with cutters in the lower part, and the cleaver is in the form of a fork.
Недостатком его вл етс невысока надежность в работе, вследствие слабого закусывани монолита грунта вильчатым скалывателем., а также сложной конструкции рабочего .The disadvantage of it is low reliability in operation, due to the weak biting of the soil monolith with a forked cleaver, as well as the complex construction of the worker.
Целью изобретени вл етсй Повышение надежности устройства в работе .The aim of the invention is to improve the reliability of the device in operation.
Указанна цель достигаетс тем, что многорезцовый рабочий орган выполнен в виде цепных бар, а подпружиненный скалыватель выполнен в виде двух зазубренных уголков, установленных под углом друг к другу и чцарнирно соединенных между собой.This goal is achieved by the fact that the multi-tool body is made in the form of chain bars, and the spring-loaded cleaver is made in the form of two notched corners, set at an angle to each other and connected to each other.
На фиг. 1 дан общий вид устройства с разрезом; на фиг. 2 - кинематическа схема устройства.FIG. 1 shows a general view of the device with a slit; in fig. 2 - kinematic diagram of the device.
Устройство состоит из корпуса 1, смонтированного в нем редуктора 2, пр моугольной приемной камеры 3, цепных бар, включающих направл ющие 4 и установленные в их пазах 5 .на ос х 6 звездочки 7 многорезцовыми цеп ми 8, при этом цепные бары расположены во взаимноперпендикул рных плоскост х, образу пр моугольный параллелепипед, и соединеныпосредством редуктора 2 и вала 9 с приводом (на чертежах не показан), и выполнены в виде двух зазубренных уголков 10, шарнирно смонтированных на ос х 11 под тупым углом в нижней части керноприемной камеры 3 и подпружиненных относительно нее посредством пружин 12.The device consists of a housing 1, a gearbox 2 mounted therein, a rectangular receiving chamber 3, chain bars including guides 4 and sprockets 7 mounted on their grooves 5. On axles 6 and 7, multi-cutter chains 8, while the chain bars are arranged in mutual perpendicular planes, forming a rectangular parallelepiped, and connected by means of gear 2 and shaft 9 with a drive (not shown), and made in the form of two notched corners 10, hinged on axis x 11 at an obtuse angle at the bottom of the core receiver 3 and prod dinner relative to it by means of springs 12.
30 Работает устройство следующим образом . Включаетс привод (на чертежах не показан) цепнЫК бар.и через вал 9 и редуктор 2 привод тс во вращение звездочки 7. Многорезцовыми цеп ми 8 из исследуемого мерзлого грунта осуществл етс выпиливание монолита, который поступает в керноприемную камеру 3 и скользит по поверхности зазубренньос уголков 10, отжима их вершины к стенкам керноприемной камеры 3; пружины 12 при этом сжимаютс . После заглублени устройства на высоту керноприемной Кс1меры 3 привод цепных бар отключают и устройство извлекают из исследуемого мерзлого грунта. При этом происходит надежное закусывание зазубренными уголками 10 выпил гнного монолита мерзлого грунта и его скапывание по. всем гран м.30 The device works as follows. The drive (in the drawings not shown) of the chain bar is turned on, and through the shaft 9 and the gearbox 2 is driven into rotation of the sprocket 7. Multicutting chains 8 from the studied frozen soil are sawed out the monolith, which enters the core chamber 3 and slides along the surface of the serrated corners 10, pressing their tips to the walls of the core receiver chamber 3; the springs 12 are compressed. After the device is deepened to the height of the core-receiver Ks1mery 3, the drive of the chain bar is disconnected and the device is removed from the frozen ground under study. When this occurs, a reliable bite of the jagged corners 10 drank the gnaric monolith of the frozen soil and its digging along. all grand m
