Shape ring is not departed from strip plate, and fixed block along the longitudinal direction is respectively and fixedly provided on the downside of straight-flanked ring both ends, and fixed block mutually leans on
Close end face is inclined-plane, and two inclined-planes are in the V shape of opening upwards, and two inclined-planes do not contact；It is placed in straight-flanked ring and communicates up and down
Rectangular frame, horizontal sieve, the container of sieve and frame composition opening upwards are fixed in frame through multiple screws；Often
There is a level to run through the push rod of shell on the right side of a straight-flanked ring, the right end of push rod is placed on the right side of shell, and there have on the right side of shell to be vertical
Installation and the crank that can actively rotate have multiple rod journals on crank, and multiple rod journals and multiple push rods correspond, often
A connecting rod is hinged on a rod journal, the connecting rod other end and push rod are hinged, and rod journal, connecting rod and push rod constitute slide crank
Block mechanism.
The utility model clever structure realizes field and carries out silt acquisition testing, silt is sufficiently sieved, structure letter
It is single, it is easy to accomplish.
Detailed description of the invention
Fig. 1 is the utility model front sectional view.
Fig. 2 is the structure chart of the shell in the utility model.
Fig. 3 is the structure chart of part in the utility model.
Specific embodiment
Further description is made to specific embodiment of the present utility model below in conjunction with attached drawing.
It is provided by Fig. 1 to Fig. 3, the utility model includes the vertical rectangular housing 1 placed and communicated up and down, is had in shell 1
Multiple straight-flanked rings 2,2 lateral wall lower end outside of straight-flanked ring have protrusion, have on the inside of the front-rear side walls of shell 1 multiple along right and left
To fixed strip plate 3, straight-flanked ring 2 is placed on two correspondence strip plates 3 and can move left and right along strip plate 3, straight-flanked ring 2
On protrusion straight-flanked ring 2 is not departed from strip plate 3, fixation along the longitudinal direction is respectively and fixedly provided on the downside of 2 both ends of straight-flanked ring
Block 4, the end face close to each other of fixed block 4 are inclined-plane, and two inclined-planes are in the V shape of opening upwards, and two inclined-planes do not contact；Rectangle
It is placed with the rectangular frame 5 communicated up and down in ring 2, is fixed with horizontal sieve 6, sieve 6 and frame through multiple screws in frame 5
The container of the composition opening upwards of frame 5；The push rod 7 that each 2 right side of straight-flanked ring has a level to run through shell 1, the right end of push rod 7
It is placed in 1 right side of shell, has crank 8 that is vertically-mounted and can actively rotating on the right side of shell 1, there are multiple rod journals on crank 8, it is more
A rod journal and multiple push rods 7 correspond, and a connecting rod, the connecting rod other end and push rod 7 are hinged on each rod journal
Hingedly, rod journal, connecting rod and push rod 7 constitute 8 slide block mechanism of crank.
In order to after the completion of screening, conveniently remove each container, it is provided with opening on the front side wall of the shell 1, is open
1 front side board of shell is divided into left and right two parts, and the length being open is not less than the length of container.
In order to install crankshaft, it is fixed with bracket outside 1 right side plate of shell, crankshaft is connect with holder pivots.
It is separated to save the grains of sand of manpower and different-diameter, 8 upper end of crank is connected with motor 9,9 band of motor
Dynamic crank 8 rotates, and motor 9 is fixed on bracket.
In order to also collect fine particle, 1 lower end of shell is placed with horizontal Material collecting box for harvesting, on Material collecting box for harvesting
End is openning shape, and Material collecting box for harvesting can be extracted out from 1 front end of shell.
It is worth noting that, the sieve pore of the sieve 6 in multiple containers is not of uniform size, and the sieve pore of the sieve 6 of the top
Diameter is maximum, more smaller to the aperture of lower screen cloth 6；Two fixed block supports frame frame is not fallen out.
In use, collected silt is placed in the container of the top, 9 power supply of motor is connected, motor 9 drives crank
8 rotations, crank 8 drive push rod 7 to move left and right through connecting rod, and push rod 7 drives straight-flanked ring 2 to move fast left and right, realize container
Interior silt is sieved, and the maximum sediment retention of particle is in uppermost container, remaining falls to second container, together
Reason, less than the sieve diameter of sieve 6 in second container particle to falling in third container, successively downwards, up to mud
The smallest particle drops into Material collecting box for harvesting in sand, then removes out each container silt, and carries out air-drying processing, is convenient for the later period pair
The experimental work of silt.
Inclined-plane on two fixed blocks 4 effectively prevent silt to be thrown out of in dropping process, reduces error.
The utility model is with structurally reasonable, manufacturing cost is low, can require manufacture, using easily excellent according to specific screening
Point can meet the requirement of general sediment grain size analysis experiment.Specifically, collected silt sample is put into the present apparatus, it will
Silt left and right directions mulberry is quickly rocked, and effectively prevent the screening of the silt as caused by the bonding of silt uneven, reduces experiment and misses
Difference.Each aperture silt sample completed, later period of being more convenient for experimental works such as the weight measurements of different pore size silt, can be improved pair
The producing efficiency of sediment grain size grading curve, can be applied to field trial, have stronger practicability.
