Description
Technical field
The utility model relates to a kind of sand and dust gathering-device, refers in particular to a kind of rotary type sand-taped instrument for desertification monitoring.
Background technology
At present, known sand-taped instrument structure is formed by combining by main body frame, collection sandbag/box, stationary installation.For adapting to changeable wind direction, improve sand and dust acquisition precision, sand-taped instrument original structure adds wind direction guide plate (wind direction rudder), in stationary installation, bearing is installed, sand-taped instrument main body box haul can be made to change flexible rotating, achieve sand inlet and aim at direction of the wind comes from real time.But rotary type sand-taped instrument Bearing inner easily enters sand and dust, cause bearing rotary resistance to increase, have a strong impact on the dirigibility of sand-taped instrument body rotation, sand inlet effectively can not aim at direction of the wind comes from, and finally causes sand and dust Acquisition Error.In addition, sand and dust collection bag/box is all installed on main body frame, adds sand-taped instrument body weight, and with adopting the increase of sand collecting amount, bearing rotary resistance is larger, has had a strong impact on the accuracy that sand and dust gather.
China Patent Publication No. CN105043709A discloses a kind of air-flow convolution sand-taped instrument, and primary structure comprises spud pile (1), O-ring taper roller bearing assembly (2), lateral support frame (3), weathervane (4) and the husky module of collection (5); Weathervane (4) is fixed in described lateral support frame (3) one end, and the other end is affixed with the husky module of collection (5); Lateral support frame (3) is fixed on O-ring taper roller bearing assembly (2); O-ring taper roller bearing assembly (2) is fixed on spud pile (1).This sand-taped instrument significantly reduces flow velocity and the kinetic energy of gas-solid biphase flow after dust-contained airflow can be made to enter the husky module of collection, be convenient to grains of sand sedimentation, can reach air-flow and be separated with the efficient of sand and dust, thus improve measuring accuracy.And this sand-taped instrument is modular design, compact conformation is reasonable, easy accessibility, can carry out analytical test under different combinations to the stream of differing heights level.The defect that this technical scheme exists is: 1, utilize bearing assembly to fix, under the rugged surroundings that dust storm is larger, dust storm very easily enters into bearing assembly, causes the damage of equipment; 2, store up husky device to rotate with the husky device of collection, add the deadweight of whirligig, thus add the resistance of rotation, certain influence can be produced to the husky effect of collection.
The present utility model people groping through long-term and put into practice, continuous exploration and improvement, for difficult point and the limitation of current sand-taped instrument, the rotary sand-taped instrument of a kind of bearing-free of the utility model is by improving its structure, the bearing-free achieving sand-taped instrument by catch and back up pad rotates, and avoids the destruction because dust storm causes bearing assembly, is separated by husky for storage device with the husky device of collection simultaneously, alleviate the husky device deadweight of collection, improve the effect of this instrument collection sand.
Utility model content
The object of the rotary sand-taped instrument of a kind of bearing-free of the utility model is to provide a kind of husky device of collection that can realize rotating without the need to bearing arrangement.
For realizing above-mentioned goal of the invention, the technological means that the rotary sand-taped instrument of a kind of bearing-free of the utility model adopts is: the rotary sand-taped instrument of a kind of bearing-free, comprise wind direction guide plate, balance bob, adopt sand tube, catch, back up pad, storage Sand Bucket, protection bucket, describedly adopt the pipe that sand tube is metal material, wind direction guide plate, balance bob can be installed in upper end, and catch is fixed at top position, lower end;
Described wind direction guide plate and balance bob are fixed on adopts both sides, sand tube top, and the two is 180 degree;
Described back up pad front center opens circular hole, and Circularhole diameter is a bit larger tham the external diameter adopting sand tube, and one section of metal tube is installed at the back side place of back up pad center hole, and round tube inside diameter is a bit larger tham adopts sand tube external diameter;
Between balance bob and catch, cut one section of even gap as sand inlet along adopting sand tube longitudinal centre line, sand inlet is positioned at immediately below balance bob and back in wind direction guide plate, in air-flow, sand and dust are entered by sand inlet and adopt in sand tube;
When this instrument is installed, sand tube lower end will be adopted and insert back up pad center hole, until catch contacts completely with back up pad, and back metal pipe box is being adopted outside sand tube, rely on the friction of catch and back up pad, supporting role and back up pad back metal pipe to the effect of contraction adopting sand tube lower end, under the braking of wind direction guide plate, adopt sand tube realize stable rotation; Storage Sand Bucket is positioned in protection bucket, and storage Sand Bucket aimed at by back up pad back metal pipe, enters the sand and dust adopting sand tube sand inlet and can all fall in storage Sand Bucket.
The utility model also comprises following scheme: catch and lower supporting plate surface of contact smooth, be metal material, reduce adopt sand tube rotate time produce friction force; Adopt the sealing of sand tube upper end, according to the height needs of reality test, adopting sand tube and adopting the sand inlet on sand tube of corresponding length can be made; According to acquisition time or dust storm intensity, corresponding size storage Sand Bucket can be made; In support plate edge, gas outlet is installed, gas outlet sectional area is more than or equal to and adopts the sand tube sand inlet total area.
Adopt above-mentioned technological means, the beneficial effect of the rotary sand-taped instrument of a kind of bearing-free of the utility model be can realize bearing-free can flexible rotating, overcome bearing enter sand and dust can not the shortcoming of flexible rotating; Meanwhile, sand and dust Storage Box and rotating main body are departed from, reduces rotating main body weight greatly, and then effectively reduce the rotational resistance of rotating main body.The rotary sand-taped instrument catch of bearing-free and back up pad, adopting sand tube and back up pad back metal pipe and form turntable, and then instead of bearing wheelwork, avoiding bearing rotates difficulty problem because entering sand.Meanwhile, catch can stop earth's surface sand and dust enter adopt the back side under sand tube and back up pad metal tube gap in, ensure that the dirigibility of rotation.By storage Sand Bucket with adopt sand tube and be separated, alleviate whirligig weight largely.Therefore the utility model structure is simple, installs, dismantles easily, use operation steps simple.
