Technical Field

The invention relates to a combined device, in particular to a simple soil screening combined device in a laboratory.

Background

In the geotechnical test, the fine soil with different particle sizes is screened according to the test requirements, which is an essential part of the test. Particularly, the soil screening and vibrating machine can cause a series of problems of power waste, troublesome cleaning and the like when a small amount of soil is screened by the soil screening and vibrating machine with one or two particle sizes. The experimenters typically used manual soil screening for screening. However, fine soil dust often flies in the process of manually screening soil, which not only causes fine soil loss, but also damages the cleanness of a laboratory, and easily causes waste of soil dust and fine-particle-size soil sucked by experimenters.

At present, a detachable aluminum disc-shaped soil collector is usually connected below a soil screening device at home and abroad. But from the specific experimental process, the problems of clean laboratory and simple operation cannot be solved well. Therefore, under the background of continuously advocating environmental protection and improving work efficiency, it is necessary to improve the structural design of the soil screening combination device to improve the test efficiency.

Disclosure of Invention

The invention aims to overcome the defects of the existing device and provide a combined device capable of effectively improving soil screening efficiency.

The idea of the invention is as follows: the upper part of the combined device is a common soil sieve required by the test, a groove on the outer side of the bottom of the soil sieve is connected with the funnel-type soil receiver, and the bottom of the funnel-type soil receiver is designed into a spiral bottle mouth and is connected with the bottle stopper. When soil screening is started, the combined device is connected, the soil screen is connected with the funnel type receiver, and the bottle stopper is screwed down. The screened soil with a certain mass is poured into the soil screen, and the screen is properly rocked to take fine soil, so that the screened soil can be directly collected into the funnel type soil collector in the soil screening process, soil dust is prevented from being sucked by experimenters and fine soil loss caused by soil dust volatilization is avoided, and cleanness of a laboratory is guaranteed. After soil screening is completed, the funnel type soil receiving device is disassembled, the position of the bottle plug is aligned to the soil containing container above the electronic scale, and the bottle plug is unscrewed to directly measure the mass of the soil to be screened. This reduces inconvenience and time waste caused by weighing the soil mass at the transfer location during the soil screening process. Because this composite set is simple easy to operate, can bring very big facility for laboratory personnel, the greatly reduced sieve soil time and the soil loss volume improve test efficiency.

The invention is realized by the following steps: a simple soil screening combination device suitable for screening soil particles with different particle sizes in a laboratory. The combined device mainly comprises soil sieves with different diameter screens, an improved funnel type soil receiving device and a bottle stopper, wherein the upper part of the combined device is the soil sieve with the particle size required by an experiment, the lower part of the combined device is the funnel type soil receiving device which is connected by a groove at the outer edge of the bottom of the soil sieve, and the bottom of the funnel type soil receiving device is designed into a spiral bottle mouth and is connected with the bottle stopper. When soil screening is started, the combined device is connected, the soil screen is connected with the funnel type soil receiving device, and the bottle stopper is screwed down. The screened soil with certain mass is poured into the soil screen, the screen is properly shaken to take fine soil, the screened soil can be directly collected into the soil receiving device in the soil screening process, the funnel type soil receiving device is dismounted after the soil screening is finished, the position of the bottle plug is aligned to the soil containing container above the electronic scale, and the bottle plug is unscrewed to directly measure the mass of the screened soil.

The soil sieve is a laboratory standard soil sieve

The size of the funnel type receiver is consistent with that of a standard soil sieve, and the material can be plastic, aluminum or iron according to the requirement.

The invention has the following beneficial effects:

(1) avoids the laboratory personnel from sucking the soil dust and the loss of fine soil caused by the volatilization of the soil dust, and ensures the cleanness and tidiness of the laboratory

(2) The combined device is simple and easy to operate, and can greatly reduce the soil sieving time.

(3) The funnel-type soil receiving device can be used only by slightly changing the funnel, replaces the traditional aluminum disc-shaped soil receiving device in a laboratory, and can be used as a common funnel after being disassembled, so that the funnel-type soil receiving device has multiple functions, and the cost is reduced.
