Abstract
The utility model discloses a soil sampler, which comprises a pedestal with a center hole, a screw passing through the pedestal center hole, and a drill bit connected with the lower end of the screw; the screw is orderly sleeved with a soil-scraping device, a bayonet nut, a bearing, and a large bevel gear; The bayonet nut fixes the soil-scraping device on the pedestal by the bayonet slot, and is in threaded connection with the screw; the large bevel gear is engaged with a small bevel gear, and a center hole of the large bevel gear is connected with the screw through a sliding key mounted in a clamping slot on the screw; the small bevel gear is connected with a power input shaft through the bearing; the upper end of the screw is connected with a drill rod joint. The soil sampler of the utility model is simple in structure, and convenient for operation, is flexible and laborsaving.
Description
Technical field
The utility model relates to a kind of soil sampler.
Background technology
At present, commonly used pedology sampling thief mainly by handle, connecting link, storage earthenware, sampling pedal, unload a kind handle, long handle piston, mill teeth, card with holes and sliding tray etc. and form.Middle and upper part, connecting link right side has sliding tray.The left side of storage earthenware and connecting link weld slightly top is provided with the sampling pedal.Storage is provided with the long handle piston in the earthenware, and piston is in the bottom, and long handle is in the connecting link of hollow, and handle is connected the position, middle and upper part of long handle, leans out from the sliding tray of connecting link.The connecting link inner chamber of 5-10cm position is provided with card with holes under connecting link inner chamber that stores up 5-10cm position on earthenware and the connecting link weld or sliding tray, and the piston long handle passes from card hole, can slide by easy on and off.This sampling thief complex structure, operation easier is big, and effort.
Summary of the invention
To the problems and shortcomings that exist in the above-mentioned prior art, the purpose of the utility model is to provide a kind of simple in structure, easy to operate, flexible and laborsaving soil sampler.
The technical scheme that realizes above-mentioned utility model purpose is; A kind of soil sampler; By a base that is provided with center pit, pass the screw rod of said centre hole of base and the drill bit that is connected with the screw rod lower end is formed, be with scraping device, bayonet nut, bearing, bevel gear wheel on the said screw rod successively; Said bayonet nut is fixed on the scraping device on the base through bayonet slot, and cooperates with said screw flight; Said bevel gear wheel and bevel pinion engagement, the feather key in the draw-in groove is connected its center pit on the screw rod through being installed in screw rod, and institute's bevel pinion is connected with power input shaft through bearing.
Said screw rod upper end is connected with drill pipe sub.When the degree of depth that fetches earth during, can add the prolongation drilling rod in the drilling rod junction greater than a spiro rod length.
Principle of work:
Power is imported from the right side, drives the bevel pinion rotation, and the engagement through big bevel pinion is sent to power on the bevel gear wheel.The centre has screw rod to pass, and screw portion is equipped with feather key, and head is equipped with drill bit.Drive down in the rotation of bevel gear like this, because nut fixes, make screw rod rotate and move, thereby make among the soil sample barrel entering soil, fetch earth as required.During the screw rod backhaul, the work of scraping device can be cleared up foreign material in the screw thread.
When the degree of depth that fetches earth during greater than a spiro rod length, can add the prolongation drilling rod in the drilling rod junction, for easily manufactured, extension rod is made hollow polished rod, is installed on the bottom of screw rod, is convenient to save cost.
The utility model sampling thief can directly add miniature gasoline engine, and the centering performance of screw thread can realize high-quality and efficient low consumed green engineering thought in addition.Ingenious part is that like the improvement of drill bit and the fixed form of nut, scraping mechanism etc. are a kind of simple in structure, easy to operate, flexible and laborsaving soil sampler with worm drive and the gear-driven innovation that combines with microtexture.
