Abstract
The utility model relates to a kind of modified cutting ring assembly, and comprise cutting ring and cutting ring handle, cutting ring top is provided with lengthening ring, and the inwall lengthening ring is provided with spiral internal tooth, and the outer wall top of cutting ring is provided with spiral external tooth, and this spiral external tooth engages with the spiral internal tooth lengthening ring; Cutting ring handle has the pressure-bearing collar, and the pressure-bearing collar is made up of circular cast iron plate and tubular cast iron ring, and circular cast iron plate is evenly provided with multiple manhole around the center of circle.The utility model is to these two improvement of cutting ring assembly, and one is the amount of fetching earth increased and make top disturbed sample enter lengthening ring, and the soil body lengthened in ring is wiped off with scraper when assembly takes out, and decreases the impact of sample on test findings of loosening the soil of disturbance; Two is to see from the pressure-bearing collar whether the soil body just fills up space in cutting ring, prevents the artificial compression occurred because of invisible.
Description
Technical field
The utility model relates to civil engineering work soil matrix on-site detecting device technical field, particularly relates to a kind of modified cutting ring assembly.
Background technology
In the work of civil engineering work soil matrix Site Detection, it is the on-the-spot earth base density detection method be in daily use that core cutter method does density, the instrument of the method---cutting ring is easy to carry, test method is easy to operation, is the first-selected detection method that earth base density detects.But usually there is the problem that Parallel testing result error is large in Site Detection, traced it to its cause two: one is that core cutter method is in the process of fetching earth, cutting ring and cutting ring handle form a space, utilizing cutting ring handle, cutting ring is pressed down in the process of burying, air in space hinders soil matrix soil to enter cutting ring, and the soil body of cutting ring internal upper part is because of disturbance, and volume becomes large, should enter the soil body in cutting ring, thus cause Density Detection result less than normal when finally causing the soil body entered in cutting ring to be less than Density Detection; Two is because integral loop knife assembly inside is invisible, cannot learn whether the soil body fills up cutting ring, occurs overvoltage and causes the soil body in cutting ring artificially to be compressed, occur the situation that Density Detection result is bigger than normal.For solving this two problems, cutting ring handle and cutting ring being done an improvement, having made a set of Novel ring knife assembly.
Utility model content
The technical matters that the utility model solves is to provide a kind of modified cutting ring assembly, to solve the shortcoming in above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
The utility model provides a kind of modified cutting ring assembly, comprise cutting ring and cutting ring handle, described cutting ring top is provided with lengthening ring, and the inwall lengthening ring is provided with spiral internal tooth, the outer wall top of cutting ring is provided with spiral external tooth, and this spiral external tooth engages with the spiral internal tooth lengthening ring; Described cutting ring handle has the pressure-bearing collar, and the pressure-bearing collar is made up of circular cast iron plate and tubular cast iron ring, and circular cast iron plate is evenly provided with multiple manhole around the center of circle.
In the utility model, described manhole quantity is five.
In the utility model, described cutting ring and cutting ring handle are cast iron quality.
In the utility model, described circular cast iron plate and tubular cast iron ring are welded as a whole.
Advantage and beneficial effect:
Former cutting ring assembly comprises cutting ring and cutting ring handle two parts, and the cutting ring after improvement adds lengthening ring, the cutting ring handle after improvement, and be increases by five manholes on the circular cast iron plate body that the pressure-bearing collar is original.The utility model is to these two improvement of cutting ring assembly, and one is the amount of fetching earth increased and make top disturbed sample enter lengthening ring, and the soil body lengthened in ring is wiped off with scraper when assembly takes out, and decreases the impact of sample on test findings of loosening the soil of disturbance; Two is to see from the pressure-bearing collar whether the soil body just fills up space in cutting ring, prevents the artificial compression occurred because of invisible.These two improvement enable cutting ring assembly avoid the test findings deviation that should not occur, reduce earth base density metrical error, improve test accuracy, and practicality is good, is with a wide range of applications.

Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See the modified cutting ring assembly of Fig. 1 ~ 5, it comprises cutting ring 1 and cutting ring handle 2.
Cutting ring 1 top is provided with and lengthens ring 3, lengthening ring 3 and cutting ring 1 are all tubular cast-iron structure, the inwall lengthening ring 3 is provided with spiral internal tooth 31, the outer wall top of cutting ring 1 is provided with spiral external tooth 11, this spiral external tooth 11 with lengthen the spiral internal tooth 31 of ring and engage, make lengthening ring 3 can need to be installed on cutting ring 1 or from cutting ring 1 according to test and take off; Cutting ring 1 has cutting ring mouth 12.
Cutting ring handle 2 comprises the pressure-bearing collar 4, and the pressure-bearing collar 4, by circular cast iron plate 41 and the integrally welded structure of tubular cast iron ring 42, circular cast iron plate 41 is evenly provided with 5 manholes 43 around the center of circle.
Using method of the present utility model:
Before using, first by spiral internal tooth 31 and spiral external tooth 11, cutting ring 1 and lengthening ring 3 are linked together, then the pressure-bearing collar 4 free trip buckle is being lengthened ring 3 top, this component integration is placed on the soil matrix of leveling, cutting ring mouth 12 is downward, firmly whole assembly is evenly pressed into inside soil body, when five circular holes of the pressure-bearing collar 4 have soil outwards to overflow, stop the pressure pressure-bearing collar 4, with scoop, component integration is taken out together with the soil body, take off the pressure-bearing collar 4 and lengthen ring 3, with scraper cutting ring 1 both sides are struck off and weigh, the weight of the soil body in cutting ring 1 can be recorded, the density of this soil body can be obtained divided by the volume of cutting ring 1 with weight.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
