Embodiment
Be described in detail the utility model below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of flow regulation type sand material angle of repose determinator as shown in Figure 1, comprise base 1, support bar 2, cross bearer 3, needle beam 4, flow regulation type feeder 5 and hold sand table 6, this support bar 2 is vertically fixed on base 1, this cross bearer 3 and needle beam 4 are horizontally disposed with, one end is fixedly connected with this support bar 2, and other end support lives flow regulation type feeder 5; This holds on the base 1 that sand table 6 is positioned at immediately below this flow regulation type feeder 5.
The structure of flow regulation type feeder 5 as shown in Figures 2 and 3, be made up of funnel 7, inserted sheet 8 and hose 9, the discharge nozzle radial direction of this funnel 7 is provided with penetrating horizontal type slot, this inserted sheet 8 is provided with the different circular hole in several apertures, this inserted sheet 8 and the activity grafting in consistent manner of this slot, this slot place discharge nozzle internal diameter is greater than the maximum diameter of hole of circular hole.Hose 9 is located in this funnel 7, and is positioned at below slot; This hose 9 upper end seals with this inserted sheet 8 and contacts.
Wherein cross bearer 3 and needle beam 4 carry out dual fixing respectively on the top of funnel 7 and discharging oral area, prevent the skew of rollover and the yarn outgoing position caused because sand material is overweight.
Containing the circular hole of aperture respectively 5mm, 3mm, 2mm, 1mm, 0.5mm totally 5 different pore sizes on inserted sheet 8.
Hose 9 is that for anti-leak-stopping is husky, be located at the bell mouth of inserted sheet 8 bottom, its external diameter and bell mouth internal diameter match and thickness is enough to space between closed inserted sheet and inner wall of hopper face, along being close to inserted sheet 8 lower surface on hose 9.
The installation steps of this flow regulation type sand material angle of repose determinator are:
The first step, the installation of brace table.Support bar 2 with a scale is vertically fixed on the side that specification is the base 1 of 50cm × 50cm.This part also available iron pallet substitutes, and when substituting with iron stand, need paste and fix the hard panel that an area is 50cm × 50cm on the upper surface of iron stand base, ensure enough sand district areas, meanwhile, need be equipped with the angle block gauge measuring angle of repose; When substituting with iron stand, the gradiometer measuring angle of repose need be equipped with.
Second step, the fixing and requirement for height of horizontal gird.One end clip of cross bearer 3 and needle beam 4 and screwing bolts are separately fixed on support bar, regulate the height of cross bearer 3 and needle beam 4, make cross bearer 3 be about 30cm to the vertical range of holding husky disk, the height of needle beam 4 and the distance of cross bearer 3 are the distance of the upper and lower point of fixity of feeder.
3rd step, the making of flow regulation type feeder 5 is with fixing.First, be about at the discharging opening of distance funnel 7 the linear slot that 3cm place cutting width is slightly less than bell mouth internal diameter; Then, cutting makes inserted sheet 8, and the width of inserted sheet 8 and slot width are matched, and inserted sheet 8 cuts the circular hole that a row aperture is respectively 5mm, 3mm, 2mm, 1mm, 0.5mm, afterwards inserted sheet is inserted slot; Afterwards, being that anti-leak-stopping is husky, matching and thickness is enough to the hose in space between closed inserted sheet and inner wall of hopper face, along being close to inserted sheet lower surface on hose at the bell mouth of inserted sheet bottom nested enter an external diameter and bell mouth internal diameter.So far, the making of flow regulation type feeder 5 is completed.The top of the feeder made and discharging opening are fixed on needle beam 4 and cross bearer 3 with clip respectively.
4th step, holds specification and the placement of sand table 6.The diameter of holding sand table 6 depends on the floorage of the stable sand drift that the sand material of different-grain diameter is formed, and is determined by preliminary experiment.During mensuration, the central point holding sand table 6 is aimed at the discharging opening of feeder.
5th step, measures.Sand material to be measured is added funnel, regulates inserted sheet, make wide-aperture circular hole aim at discharging opening, along with the change of sand drift form, twitch inserted sheet and make the circular hole of small-bore switch to discharging opening, the adjustment of concrete caliber size is determined by experimental observation process.Observation sand drift domatic change, when judging and measure domatic generation shearing motion and the angle of surface level, i.e. angle of repose.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
