Abstract
A kind of hand-rail type screening machine.Be characterized on sieve box reel cage, having increased devices such as a bushing screen box carriage, ratchet, ratchet, make the sieve box when making reciprocally swinging, can rotate, improved screening quality; Simultaneously hand take turns and the runner of installing connecting rods between be provided with a pair of change-speed gearing, improved screening efficiency.This screening machine can be used for sieving various granular materials, is a kind of desirable soil test instrument.
Description
Present design relates to a kind of device that mixes building stones and other particulate materials that sieves.Belong to the soil test instrument.
When building various cement concrete engineerings or pitch and cement concrete road, need by designing requirement, the building stones with all size mix according to a certain percentage, mix with a certain proportion of water mix, sand, water or pitch is arranged, just can reach the design strength of the phase of giving.For reaching this purpose, need often to measure the grating of mixing building stones in design, construction, the building stones of promptly measuring all size account for the percentage that mixes building stones weight.This at first needs to separate by granular size mixing building stones.It is with artificial shaker screen box that the past screening mixes building stones method commonly used.Be about to mix the sample of building stones, shake repeatedly in the sieve box of packing into, will sieve less than the building stones of this sieve box particle diameter with a certain particle diameter.Then remaining mixing building stones are reinstalled in the sieve box with big one-level particle diameter and shake repeatedly once more ...So repeatedly for several times, until finishing by the designing requirement screening.To sieve the building stones that fall then at every turn and collect also weighing calculating respectively, can draw the grating of this kind mixing building stones sample.Adopt the method for artificial screening, the screening time is long, and labour intensity is big.Once developed electronic abroad and two kinds of screening machines of hand-rail type.See TG-108 type electric screen grader and the hand screening machine of TG-104 type that Japanese TANIFUJI company produces.Electric screen grader has characteristics such as screening time weak point, efficient height, but must could use in the place that power supply is arranged.The hand-rail type screening machine is simple in structure, and reliable operation is suitable in the job site that does not have power supply and uses.But hand wheel of existing hand screening machine rotated a week, and the sieve box can only move back and forth once, and efficient is lower.Simultaneously because the sieve box is a garden shape, do the oscillating riddle timesharing at the sieve box, be in the garden shape sieve box and maximum gauge place that swaying direction is perpendicular mix building stones, its motion is subjected to sieving the restriction of box wall, become the dead angle of screening motion, influence the screening quality that mixes building stones, can not accurately measure the grating of mixing building stones.
The purpose of the technical program is in order to overcome hand pendulum-type screening machine above shortcomings, a kind of hand rotary speed increase bolting mill that improves screening efficiency and quality to be provided.
The concrete structure of the technical program is so hinged on base four rocking bars to be installed, and the upper end of rocking bar is hinged to be equipped with a sieve box reel cage.Set up a rotatable sieve box bracket on sieve box reel cage, the lower end of sieve box bracket is equipped with a ratchet, and ratchet is stirred by a ratchet that is installed on the pole that is fixed on the base.Sieve box reel cage is affected by a connecting rod.One end of connecting rod is hingedly mounted on the sieve box reel cage, and the other end of connecting rod is hingedly mounted on the off-centered edge of a runner.A pair of change-speed gearing runner and hand take turns and change-speed gearing is installed on the hand wheel support that is fixed on the base are being arranged between runner and hand the wheel, and the sieve box is installed on the sieve box bracket, compresses with pressing plate.When shaking hand the wheel, the hand wheel by change-speed gearing, runner and connecting rod affects sieve box reel cage to make reciprocally swinging, and ratchet is stirred ratchet simultaneously, makes sieve box bracket and superincumbent sieve box is installed, and when making reciprocally swinging with sieve box reel cage, rotates.
Fig. 1 is an embodiment of the technical program, and among the figure: 2,17 2,18 of 1 base, 2 ratchet poles, 3 rocking bars, 4 sieve box reel cages, 5 sieve box brackets, 6 steady braces, 7 sieve boxes, 8 pressing plates, 9 nuts, 10 ratchets, 11 ratchets, 12 connecting rods, 13 runners, 1,15 1,16 change-speed gearings of 14 change-speed gearings are hand takes turns, 19 handles, 20 hand wheel supports.
In conjunction with the embodiments the technical program is further described.Hinged on base 1 four rocking bars 3 are installed, the upper end of rocking bar 3 is hinged to be equipped with a sieve box reel cage 4.Set up a rotatable sieve box bracket 5 on sieve box reel cage 4, the lower end of sieve box bracket 5 is equipped with ratchet 10, and ratchet 10 is stirred by the ratchet on the pole 2 that is installed on the firm banking 1.Sieve box rocker 4 is affected by connecting rod 12, and an end of connecting rod 12 is hingedly mounted on the sieve box reel cage 4, and the other end of connecting rod 12 is hingedly mounted on the off-centered edge of runner 13.At runner 13 and handly a pair of change-speed gearing 14,16 is arranged between taking turns 18, can increase the hunting frequency of sieve box reel cage 4 by change-speed gearing 14,16.Runner 13, hand take turns 18 with change-speed gearing 14,16, be installed on the support 20, support 20 is fixed on the base 1.Sieve box 7 is installed on the sieve box bracket 5, compresses with pressing plate 8.Hand when taking turns 18 when shaking, by change-speed gearing 14,16, runner 13 and connecting rod 12 affect sieve box reel cage 4 to make reciprocally swinging.Ratchet 11 is stirred ratchet 10 simultaneously, makes sieve box bracket 5 and superincumbent sieve box 7 is installed, and when making reciprocally swinging with sieve box reel cage 4, rotates.
The hand-rail type screening machine that the technical program provides has the advantages such as simple in structure, reliable operation, can also improve efficient and the quality of screening, is the screening plant of comparatively ideal mixing building stones.
