Description

The automatic continuous sampling machine of vehicle-mounted cleaned coal

The utility model belongs to mechanical engineering gearing field, is specifically related to a kind of automatic continuous sampling machine of vehicle-mounted cleaned coal for the quality testing of loading the cleaned coal that carries, transports with car is designed.

In prior art 95240358 patent disclosures a kind of " going into factory's coal mechanical sampling machine " be that a top by the four-post vertical steel framework is provided with motor and variable speed drive, wire rope, wire reel, at last with wire rope with place the coal taking head platform of framework to join, this platform can be moved up and down along four root posts, platform is provided with a framework that coal taking head is housed, the motor that can drive the coal taking head side-to-side movement is equipped with on the right side of framework, variable speed drive and wire rope, driving wheel group, the left side of framework is equipped with and can be driven framework motor and speed change gear, wire rope and the free wheel group that move front and back on platform.Coal taking head is a steel cylinder of adorning the helical blade and the manganese steel vertex of a cone in one.Its shortcoming is: sampling head needs move up and down with framework when 1, taking a sample, and the profile of framework is easily conflicted with vehicle, and limited to sampling depth.2, sampling process is counter-rotating → feeding → stall → upwards feeding → laterally or length feed → just producing material, the process complexity, and the time is long, and downward because of discharging opening, and sampling precision is not enough.3, because of in its sampling sleeve bearing being installed, so easy coal dust stops up.4,, easily take place in the sampling process owing to get full coal sample in the sleeve if untimely parking easy burn-out motor or damage transmission shaft because the sampling sleeve is totally-enclosed except that following end entrance.5, the wet coal of the northern cold open work of incompatibility easily with in the tube freezes and is in the same place.

The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of to loading the automatic continuous sampling machine of the cleaned coal that carries, transports with car.

The technical scheme that the utility model provides is: build a construction platform, can hold vehicle under the platform and pass through.Platform is provided with two transverse movement guide rails, be equipped with wide 120mm～150mm between guide rail across the slotted hole of platform and laterally travelling car and locking position screw, the sampler mainframe is contained on the dolly, the left side of mainframe is a reducing gear, the right side is that X-gear rolls row, and the rear portion is the feed motion motor.Be sliding rack and slide plate in the gathering sill of mainframe front portion, sampling head is contained on the slide plate.

Feed motion is that X-gear rolls row by the motor via reducer structure, drives tooth bar slide plate and sampling head, the material sample that can move up and down and adopt different depth.Trolley is done transversal displacement and locking on guide rail, adjust the position, the left and right sides of loaded material sampling on the vehicle and the front and back parking spot of vehicle, determines the some position of sampling.

Feed motion adopts a plurality of even number tooth X-gears to roll the row while and a tooth bar engagement drives the tooth bar motion.

Sampling head is one and is made up of bearing bracket stand, belt gear and main motion motor and screw rod sleeve and crushing head, bearing and main shaft are housed in the bearing bracket stand, the main shaft upper end is connected with motor by belt gear, the lower end is connected with motor by belt gear with the screw rod upper end, the lower end connects with the screw rod upper end, screw rod lower end head is welded with the stainless steel crushing head, and screw rod is contained in the sleeve, and the sleeve upper end has discharging opening.The screw rod head is welded with and has the top crushing head of centering, and the upper end is connected with the main shaft of bearing bracket stand, in order to the gap of control helical blade and sleeve.

During use, adjust locking (adjusted 2-3 time and get final product in general one day) behind the transverse movement dolly position, by the selected sampling spot in the position of stopping before and after the staff vehicles, start the main motion motor, start the sampling of feeding motor again, coal sample constantly flows out from overlapping letter upper end discharging opening in the sampling process, show according to degree of depth groove and depth needle, can adopt the material sample of any degree of depth, after sampling finished, counter-rotating feeding motor made sampling head rise, wraparound main movement shaft get rid of the heels sample in the sleeve.

The utility model has the advantages that: the airframe structure compactness, profile is little, the indoor and outdoor operation all can, easy to process, cost is low, sampling precision and efficient height, the sampling scope is wide, can be little bulk, powder, mud shape.Be specially adapted to vehicle-mounted cleaned coal sampling, convenient maintenance.Can fix a point, break and freeze layer sampling by fixed continuously layer simultaneously.

Further specify as follows below in conjunction with accompanying drawing:

Accompanying drawing 1 is the structural representation of facing of the present utility model.

Accompanying drawing 2 is that the broken section structural drawing is looked on a left side of the present utility model.

Accompanying drawing 3 is the broken section structural drawing of overlooking of the present utility model.

Accompanying drawing 4 is sectional structure charts of sampling head of the present utility model.

Accompanying drawing 5 is that bottom and top feed even number tooth Modified Gear Transmission of the present utility model is rolled the row schematic diagram.

With reference to the accompanying drawings, automatically the continuous sampling machine is 1 to be provided with cross slide way 2 on the construction platform, top is equipped with frame 13, upper and lower feeding reducing gear 4, sampling head 5 and horizontal travelling car 3, by horizontal travelling car moving and locking in cross slide way, select the lateral seat cursor position of sampling spot.By the front and back position of material containing vehicle parking being determined vertical coordinate of sampled point.Bottom and top feed motor 14 is by small belt pulley 12 afterwards, big belt pulley 11, gear reduction 4,
