Abstract

The utility model discloses a moving type gulch-gold washing and choosing device which is adapted to mechanically mine a placer mine. The washing and choosing device applies a hinge movable grate mechanism, a fast-change upper vibration screen mechanism, a hollow sleeve tube rack and a direction change walking wheel train in the design through taking centrifugal vibration elements as the foundation. Therefore, the performance of an original washing and choosing device is more superior. The economic cost of placer mine mining can be greatly reduced, and the economical benefit of the mine can be improved.

Description

Moving type gulch-gold washing device

The utility model belongs to a kind of panning mechanical field, particularly a kind of washing and screening plant that is used for the open-air gravel mine exploitation and sorts.

Existing gold dust washing ore deposit device as device as described in the Chinese patent application 85102450 in the setting angle of grid on the charging aperture fix, during screening, bigger gravel (greater than 200mm) must be under artificial help, roll in wet washer one side along the gravel chute by grid, during to some, release by bull-dozer again.Because big gravel generally will account for more than 20% of ore total amount in the ore dressing scene, by a dead lift, labour intensity is very big fully, and if by strengthening the powerful discharge of vibratory sieve and loop chain Transport Machinery gravel, the device fabrication cost that certainly will be multiplied again reduces Mechanical Reliability.Other defective that this class device remains has: vibrating screen mesh and sieve nest are structural member, link together with welding or screw, in case damage repair is very inconvenient; Rotating shaft is exposed to be provided with, and the protection facility is not arranged, and sand grains adheres on it when causing work, influences efficient and service life; In addition, the weight of this washing and screening plant is bigger, and structure is also complicated, support for moving with sledge again, thus move once, " needing the bull-dozer more than 180 horsepowers to drag " (see CN85102450A specification the 8th page), mobility is not strong.

The purpose of this utility model is to overcome in the prior art weak point in the Chinese patent application 85102540 described device techniques particularly, provides a kind of washing effective, portable gravel mine washing and screening plant simple and reliable for structure.

For achieving the above object, the utility model designer makes following improvement to original device: make grid be movably installed in the top of apparatus main body, so that utilize machinery (hopper on the excavator) to get rid of bigger gravel; Between the screen cloth of last vibratory sieve and sieve nest, a kind of mechanical self-latching clamp mechanism is set, makes it easy to the Fast Installation and the dismounting of vibratory sieve, help its maintenance, rotation axis seal is installed in the casing support, improve its efficient and service life; Increase the mobility of whole device in addition.

Below with reference to the time figure the utility model is described in detail.

Fig. 1 is the general assembly schematic diagram of portable gold dust washing and screening plant.

Fig. 2 goes up the cutaway view (A-A section) at eccentric vibrating wheels and rotating shaft position for this device

Referring to accompanying drawing, this portable gold dust washing and screening plant is by grid (1), upper and lower feed hopper (2,3), gravel chute (4), eccentric vibrating wheels (5), rotating shaft (6), up-down vibration sieve (7,8), front and back hitch frame (9,10) and cleaning sparge pipe parts such as (11) constitute.One end of grid (1) is provided with handle (12), the other end is fixed in the top of washing and screening plant main body with hinge (13), when having a considerable amount of big gravel on the grid, the excavator hopper on the available charging hopper promotes the handle of grid one end in passing, the gravel of can draining like this.Be provided with in the bottom of last vibratory sieve (7) screen cloth several be " " the mechanical self-latching clamp mechanism (14) of type, be provided with the crossbeam (15) of equal number in the bottom of this sieve nest, during the vibratory sieve action, crossbeam (15) is lived in the holding of self-locking clamp mechanism, and is solid and reliable, can realize that at ordinary times the fast quick-detach of top sieve screen cloth changes the outfit.Rotating shaft (6) is installed in the casing support (16) (seeing accompanying drawing 2), and the two has done excellent sealing, and casing support (16) is fixed, and eccentric vibrating wheels (5) is installed in both sides, and its counterweight can be regulated.Because during work on the spot, a large amount of gravels are discharged under the rear portion wheel that is piled up in apparatus main body, influence cleaning and mobile, therefore the designer is equipped with in the rear end of rear haulage support (10) and main body rack (17) between this retaining slabstone of retaining slabstone (18) and the main body rack by being connected than screw (19) carefully, be intended to meet exceed the normal forces impact down, can have disconnected safety effect.Locate to be equipped with the taper of certain density or the filter screen of other shape (20), sledge is not installed under this apparatus main body at following charging aperture (3), but be provided with the train (21) that can turn to, promptly turn to iron tyre more than four, so only need bull-dozer just can drag whole device easily with one 80 horsepowers, and can be in general road walking, mobility greatly improves.

The course of work of the present utility model is referring to Fig. 1, directly drop into gravel mine in the grid with excavator or other machinery, so bigger gravel will be trapped on the grid, gravel is long-pending many behind certain hour, available excavator hopper or other machinery will be located at the handle of grid one end and mention, make grid be inclined to certain angle, then big gravel is discharged along the gravel chute.And less gravel and ore in sand form etc. all drop to feed hopper is in the rough feed hopper, and under the flushing of feed hopper sparge pipe (22) ejection water, slide into vibratory sieve (7), sieve nest carries out sorting to gravel and the placer that leaks down under the effect of eccentric vibrating wheels (5) and spring (23), part placer after choosing enters vibratory sieve (8), upper space at vibratory sieve is equiped with the water flushing ore in sand form that cleans sparge pipe (11) ejection certain pressure, the ore in sand form of certain particle size enters feed hopper (3) by the sieve aperture of following vibratory sieve again then, enters at last in sorting chute and the gold dust separator.
