Abstract
The utility model discloses a rotatable continually soil-sampling bit belonging to a soil sample drilling device. A steel ball and a bearing ratchet wheel are arranged between a handle and a drill rod. The handle can be twisted quickly back and forth without reversing hand to make the drill rod and the drill bit drill in the ground in clockwise rotation. The device can be used for drilling soil sample, and can also be used for sampling of drilling hole in ice layer and the departments of construction, archaeology, water conservancy, etc.
Description
The utility model belongs to a kind of device of coring.
Prior art of the present utility model publication is in the weather post usefulness technical device data that meteorological scientific information research institute of Central Weather Bureau publishes in October, 1977, and its name of product is the light geotome of DHM10-1 type, and the degree of depth that fetches earth is 60cm.
Because when utilizing original light geotome coring, operating personnel hold tight handle only to a direction rotation, that need not stop changes hands.Therefore, generally need a strong gay to bore soil, it is not high to bore native efficient.The utility model is installed a ratchet device between drilling rod and handle, operating personnel needn't change hands when fetching earth operation, and common woman can hold back and forth twisting fast of handle, it is underground that drilling rod and drill bit are pierced in a clockwise direction, bores native efficient and improve more than the twice.
Accompanying drawing 1 is the twisting type geotome: the 1st, and the drill bit that fetches earth, the 2nd, drilling rod, the 3rd, keyway, the 4th, T-shaped key, the 5th, ratchet bearing box, the 6th, handle, the 7th, handle frame, the 8th, steel ball, the 9th, bearing ratchet, the 10th, locking key, the 11st, positioning key, the 12nd, guide-localization coordinate, the 13rd, handle location fore shaft.
Be marked with corresponding sign and the numeral of the degree of depth that fetches earth on the drilling rod. Steel ball 8 and the bearing ratchet 9 of handle below can allow handle back and forth to twist, and the effect of ratchet bearing box is to make rod bit bore in the direction of the clock soil. Detent mechanism can slide at drilling rod, and the positioning key 11 on it and locking key 10 are used at any time selecting the height of suitable handle twisting when boring soil.
The utility model not only can be used for coring, ice sheet punching sampling and wooden boring, also can use in departments such as building, archaeology, water conservancies.
Provide a kind of size of twisting type geotome below: length overall 1000～1500mm, drill pipe diameter 18～22mm, the long 40～50mm of handle, bit diameter 30～40mm.
Claims (2)
1, a kind of coring device of being made up of the drill bit that fetches earth, drilling rod and handle is characterized in that having the steel ball and the bearing ratchet that can work the effect of falling the wheel below handle.
2, according to the described coring device of claim 1, it is characterized in that a locking key and positioning key are arranged on the drilling rod, but handle mechanism fixes on the position that is suitable for firmly boring soil.
