Specific embodiment
The technical issues of in order to keep the utility model solved, technical solution and beneficial effect are more clearly understood, below
In conjunction with attached drawing and embodiment, the utility model is further elaborated.It should be appreciated that embodiment described herein is only used
In explaining the utility model, it is not used to limit the utility model.
As shown in Figs. 1-2, a kind of river and lake water channel dredging separating screen device, main body include the rotating cylinder 1 being obliquely installed and drive
The driving mechanism 4 that the rotating cylinder 1 rotates is moved, the rotating cylinder 1 is the cylinder 21 of both ends open, the inner wall of cylinder 21
The guide card 2 for being equipped with agitation silt sand and being sent silt sand to the inclined horizontal low spot direction of cylinder 21, the periphery of cylinder 21
If offering dry screen material hole 12, the distribution that the material-dropping hole 12 includes is set to the fine deposit on the bucket wall of 21 front end portion of cylinder
Thick silt sieve material hole on middle fine deposit sieve material hole 14 and 21 end section bucket wall of cylinder on sieve material hole 13, middle section bucket wall
15。
As a preferred option, the aperture in the fine deposit sieve material hole 13 on 21 front end portion of cylinder bucket wall is 5mm, centre
The aperture in the middle fine deposit sieve material hole 14 on the bucket wall of part is 10mm, the thick silt sieve material hole 15 on the bucket wall of barrel tip part
Aperture is 20mm, and the inclined angle of 1 relative level of rotating cylinder is≤25 °, and rotation speed is 15-20 revs/min.
The set-up mode in material hole 12 is sieved by above-mentioned silt, silt sand no longer passes through the weight of silt sand in the conventional mode
Amount effect and the ramp angles by sieve plate carry out sub-sieve work, but the silt sieve being arranged by different size expects hole 12, point
At multiple sub-sieve, the guide card 2 for rotating and being sent by cylinder 21 promotes the abundant sub-sieve of silt sand, and the silt that sub-sieve comes out
Can directly blanking at it is thin, in thin and thick silt state, the not only effective solution non-uniform problem of silt sub-sieve, but also
It is more convenient to utilize and sorting transport, it should be noted that sieve the embodiment in terms of the setting of material hole 12 above with respect to silt
It can adapt to the processing of most of river and lake silt, if encountering special ambient conditions, silt sieve material hole 12 actually can also be with
According to the specific large aperture size of different flexible settings and distribution distance etc. of the difference of environment and silt sand attribute, according to this programme
Provided enlightenment, the field technical staff property of the can adapt to adjustment and variation.
Guide card 2 be spiral helicine scraper guide card 2 and the scraper guide card with delivery inclination angle, the tilt angle of guide card is
50 ° -90 °, which not only improves delivery, and has certain barrier buffer function, can be further by scraper guide card 2
The whereabouts for preventing mud too fast without sufficiently sieving, may cause silt sand instead and sieves insufficient problem,
As much as possible more silt sand can be collected simultaneously, so as to more efficient delivery.
The surface of guide card 2 is equipped with the guide card hydrofuge through-hole 20 of fine and close distribution or through slot, the setting structure and can further mention
The permeable effect of high guide card 2 makes guide card 2 itself all have excellent water-permeable and air permeable effect, effectively avoids the occurrence of non-permeable structure
Guide card 2 cause the humidity of silt sand excessively high, influence the quality of sub-sieve.
The upper end opening of rotating cylinder 1 is charging port, and lower ending opening is blanking port, and the charging port is equipped with gear
Expect ring 3, thus prevent from being easy side leakage when silt sand pan feeding in the outside of cylinder 2, pollute and influence screening operation and is normal
Progress the problems such as.
When silt sand is imported from the feed inlet of 1 upper end of rotating cylinder, the blocking material ring 3 of charging port prevents part silt sand from leaking
Out except rotating cylinder 1, rotating cylinder 1 rotates it persistently by driving mechanism 4, while the performance of spiral helicine scraper guide card is scraped
The important function expected and prevent silt sand from depositing, the thin silt sand of particle pass through the thin mud on the bucket wall of 21 front end portion of cylinder first
Sand sieve material hole 13 carries out thin silt sand screening, then carries out secondary sieve using the middle fine deposit sieve material hole on the bucket wall of middle section
Choosing, finally again by the thick silt sieve material hole 15 on 21 end section bucket wall of cylinder, the silt sand people of screening come is protected by corresponding
Collection device collect and conveying, the above process uninterrupted can operate, and fine deposit and thick silt can sift out respectively,
Thus, efficiency and sub-sieve effect are very outstanding, and stability is reliable and controllable.
As the driving structure 4 of rotating cylinder 1, the driving mechanism 4 include set on rotating cylinder 1 blanking port from
Moving gear 5 and the driving gear 6 being engaged with driven gear 5, the driving gear 6 connect speed reducer 7, and the speed reducer 7 connects
Driving motor 8 is connect, the feed inlet of the rotating cylinder 1 is additionally provided with the rotary fixing frame 9 of the fixed rotating cylinder 1 of support,
Rotary fixing frame 9 includes support frame 10 and is flexibly connected the bearing rotation connection seat 11 of rotating cylinder 1 to realize rotating cylinder 1
Rotation and support it to remain heeling condition.
As a kind of driving structure mode for further increasing and/or replacing of rotating cylinder 1, the driving mechanism
4 include biconvex wheel drive mechanism 16, and the biconvex wheel drive mechanism 16 includes set on 1 charging port of rotating cylinder and/or falling
Expect the round driven wheel 17 of port and oppresses the oval driving gear 18 in 17 side of the round driven wheel respectively, it is described
Oval driving gear 18 be connected with driving its rotation driving motor 19.
Biconvex wheel drive mechanism 16 can be set to 1 charging port of rotating cylinder and blanking port simultaneously, can also with it is above-mentioned
Gear drives the mating combined use of drive mechanism, so that rotating cylinder 1 is able to maintain unified velocity of rotation, is driven by double cam
Mechanism is driven, since oval actuating cam 18 has compared to round driven wheel by specially designed oval actuating cam
There is variable motion profile, it, can be ellipse along correspondence by whole realization after setting that two groups of ellipse actuating cams 18 are unified
The motion profile wobbling action of round actuating cam 18, stirs silt sand, prevents silt sand due to viscosity or thickness
Etc. factors cause to deposit, further increase the effect of sub-sieve, and it is unsmooth etc. substantially to prevent silt sand silting, conveying
Problem greatly improves the quality of mud sub-sieve.
A kind of river and lake water channel dredging separating screen device disclosed by the utility model it is simple and reasonable, be capable of convenience and high-efficiency
Efficient, uniform sub-sieve is carried out to the mud of water channel cleaning.
The above-mentioned preferred embodiment for being only used for illustrating, within the spirit and principle of the utility model institute
Any modifications, equivalent replacements and improvements of work, shall fall within the scope of the present invention.
