Abstract
The utility model discloses a wire type sand discharging head for sample preparation by a sand rain method. The wire type sand discharging head is structured in such a manner that the lower part of a guide pipe (1) of the sand discharging head is funnel-shaped, a rectangular port (1a) at the lower end of the guide pipe is welded with a strip-like sand discharging head connecting plate (2) which is provided with a rectangular groove (2a) adaptive to the rectangular port (1a), the sand discharging head connecting plate (2) is in bolt connection with a sand discharging plate (3), and the sand discharging plate (3) is provided with a rectangular sand discharging port (3a) which is not greater than the rectangular groove (2a) in width. The wire type sand discharging head for sample preparation by the sand rain method is convenient to operate, high in sample preparation efficiency and good in stability.
Description
Technical field
The utility model relates to a kind of line formula for the sample preparation of sand rain method head that shakes out.
Background technology
Sand rain method and vibratory drilling method, compacting process, the method for plugging and pounding are four kinds of conventional method for making sample without cohesive soil of current Geotechnical Engineering physical simulation experiment.The scope of application of these four kinds of method for making sample is not quite similar.Wherein, the method for sand rain method sample preparation is: the sand in sand bucket enters by connecting pipe the head that shakes out, and by the sand export of the head that shakes out, is fallen into model casing and is formed sand rain, carries out sample preparation; The manual control head that shakes out in sample making course, the head that makes to shake out moves back and forth by " bow " font route, and the whole model casing of scanning covering, completes one deck stucco; Successively stucco is until complete the sample preparation of model.The natural forming process of the process of sample preparation and current deposition, aeolian sand soil layer is very approaching, is more suitable for preparing the natural sand soil layer that simulated flow deposits and aeolian accumulation forms; In the model test of research topsoil ground mechanical characteristic, geotechnical centrifugal model test especially, sand rain method sample making technology is widely applied.
The line formula sand export that existing sand rain legal system sample adopts, adopts two iron sheet pieces to process mostly, adds to stitch that wide precision is low, error is large man-hour, and also easily produce distortion in the process of using, and causes the low and poor stability of the efficiency of sample preparation; In the process of preparation soil sample, need in addition to change while shaking out width, must change the whole head that shakes out, troublesome poeration.Preparation soil sample need to be prepared the head that shakes out of a plurality of different in width, has also strengthened sample preparation cost.
Utility model content
The purpose of this utility model is to provide a kind of line formula for the sample preparation of sand rain method head that shakes out, and adopts this head that shakes out to carry out the sample preparation of sand rain method, and easy to operate, sample preparation efficiency is high, good stability.
The utility model is to realize the technical scheme that its goal of the invention adopts to be, a kind of line formula for the sample preparation of sand rain method head that shakes out, it is characterized in that: the pezzer's catheter,mushroom cathete bottom that shakes out is flat infundibulate, the rectangular opening of its lower end is welded with a web joint that shakes out for strip, a web joint that shakes out is provided with the rectangular channel that is less than rectangular opening, a web joint bolt that shakes out connects the plate that shakes out, and the plate that shakes out is provided with the rectangle sand export that width is not more than width of rectangular.
Compared with prior art, the beneficial effects of the utility model are:
One, the width shaking out determines by the width of the rectangle sand export of the plate that shakes out, rectangle sand export easily processing and precision high; And the plate that shakes out is connected with the head that shakes out by a web joint that shakes out, the integral rigidity of structure is large, makes rectangle sand export in use also not yielding, makes the efficiency of sample preparation high, good stability.
Two, in the process of preparation soil sample, need to change while shaking out width, needn't change the whole head that shakes out, only need to unclamp the bolt that connects shake out a web joint and the plate that shakes out, change after the wide plate that shakes out of other seams and again tight a bolt and can proceed sample preparation, easy to operate, further improved sample preparation efficiency.
Three, preparation soil sample does not need to prepare the head that shakes out of a plurality of different in width, only needs to prepare the plate that shakes out of the different width that shake out, and has reduced sample preparation cost.
The steel plate that the above-mentioned plate that shakes out is greater than 5mm by thickness is made.
Like this, machining precision and the rigidity of structure of the rectangle sand export of the plate that can better guarantee to shake out, further guaranteed the stability of sample preparation.
Below in conjunction with drawings and Examples, the utility model is described further.

Embodiment
Embodiment
Fig. 1-2 illustrates, a kind of embodiment of the present utility model, a kind of line formula for the sample preparation of sand rain method head that shakes out, pezzer's catheter,mushroom cathete 1 bottom that wherein shakes out is flat infundibulate, the rectangular opening of its lower end is welded with the web joint 2 that shakes out of strip, the web joint 2 that shakes out is provided with the rectangular channel that is less than rectangular opening, and a web joint 2 bolts that shake out connect the plate 3 that shakes out, and the plate 3 that shakes out is provided with the rectangle sand export that width is not more than width of rectangular.
The steel plate that the plate 3 that shakes out of this example is greater than 5mm by thickness is made.
Claims (2)
1. the line formula for the sample preparation of the sand rain method head that shakes out, it is characterized in that: the pezzer's catheter,mushroom cathete that shakes out (1) bottom is flat infundibulate, the rectangular opening of its lower end (1a) is welded with the web joint (2) that shakes out of strip, the web joint (2) that shakes out is provided with the rectangular channel (2a) that is less than rectangular opening (1a), a web joint (2) bolt that shakes out connects the plate (3) that shakes out, and the plate that shakes out (3) is provided with the rectangle sand export (3a) that width is not more than rectangular channel (2a) width.
2. according to the head that shakes out of a kind of line formula for the sample preparation of sand rain method described in claims 1, it is characterized in that: the steel plate that the described plate that shakes out (3) is greater than 5mm by thickness is made.
