Detailed Description

Referring to fig. 1-3, a spiral sand washer comprises a box body 1, a rotating shaft and a bottom plate 2, wherein the box body 1 is obliquely arranged on the bottom plate 2 through a supporting seat, two ends of the rotating shaft are arranged in the box body 1 through bearings, a servo motor 3 is arranged on the outer side of the box body 1, the servo motor 3 is in transmission connection with the rotating shaft, the rotating shaft comprises a lower half shaft 4 immersed in sand washing water and an upper half shaft 5 higher than the sand washing water, the upper half shaft 5 is arranged in a telescopic mode along the lower half shaft 4, spiral stirring wheels 6 are arranged on the upper half shaft 5 and the lower half shaft 4, and a driving device 7 for driving the upper half shaft 5 to slide is arranged on the box body 1. When the sand washing machine is used, the upper half shaft 5 and the lower half shaft 4 can be opened in a telescopic mode, the spiral stirring wheel 6 of the upper half shaft 5 and the spiral stirring wheel 6 of the lower half shaft 4 are separated, sand cannot be driven by the spiral stirring wheel 6 of the upper half shaft 5 to be discharged from a sand outlet along the bottom of the box body 1, the sand is continuously immersed in sand washing water and is continuously washed by the lower half shaft 4 and the spiral stirring wheel 6, and the effect that the washing process can be adjusted in real time according to working conditions can be achieved.

Wherein, drive arrangement 7 includes shell 8, pneumatic cylinder 9 and wedge 10, has seted up spacing groove 11 in the shell 8, and pneumatic cylinder 9 is installed in spacing groove 11, and wedge 10 is installed at pneumatic cylinder 9 expansion end, and 5 tip on the semi-axis pass box 1 and lie in shell 8, and 5 tip on the semi-axis is provided with ejector pin 12 with wedge 10 complex. In the working process, the hydraulic cylinder 9 drives the wedge block 10 to move along the limiting groove 11, and the wedge block 10 and the ejector rod 12 are matched to drive the upper half shaft 5 to extend upwards, so that the effect of separating the spiral stirring wheel 6 of the upper half shaft 5 and the lower half shaft 4 is achieved.

Wherein, the tip of ejector pin 12 still is provided with reset spring 13, and shell 8 installs swivel disc bearing 14, and reset spring 13 passes through spring holder 15 and swivel disc bearing 14 and connects. The return spring 13 presses the upper half-shaft 5 to ensure it is in a contracted state when the drive 7 is not in operation.

Wherein, the upper half shaft 5 and the lower half shaft 4 adopt key connection transmission. The key connection can be adopted, so that the transmission effect of the upper half shaft 5 and the lower half shaft 4 is not influenced in the telescopic process.

Wherein, the bottom of the higher end of the box body 1 is also provided with a sand outlet 16. Because the upper half shaft 5 can stretch out and draw back, therefore when the upper half shaft and the lower half shaft 4 shrink, the helical blade of the upper half shaft 5 transports cleaned gravel out, the helical blade of the upper half shaft 5 has a certain distance from the tail part of the box body 1, and the sand outlet 16 is arranged at the bottom of the higher end of the box body 1, so that the gravel can be discharged better conveniently.

Wherein, the bottom of the box body 1 at the joint of the upper half shaft 5 and the lower half shaft 4 is provided with a fine sand collecting port 17, a filter screen 18 is arranged in the fine sand collecting port 17, a filter plate 19 is arranged below the fine sand collecting port 17 at the outer side of the box body 1, a water tank 20 is arranged below the filter plate 19, one end of the filter plate 19 is provided with a fine sand outlet 21, and a material conveying belt 22 is arranged at the fine sand outlet 21. When the upper half shaft 5 and the lower half shaft 4 are unfolded, the spiral stirring wheel 6 of the upper half shaft 5 can drive the gravel to be continuously cleaned, the spiral stirring wheel 6 of the upper half shaft 5 cannot be in contact with the gravel to discharge the gravel, the spiral stirring wheel 6 of the upper half shaft 5 can drive the gravel to continuously move upwards to the joint of the upper half shaft 5 and the lower half shaft 4 to be continuously stirred and stirred to continuously clean the gravel, fine sand mixed with the gravel flows out from a fine sand outlet during stirring and cleaning, the fine sand is intercepted by the filter plate 19 and then falls onto the material conveying belt 22 under the washing of sand washing water, the fine sand is timely conveyed away through the material conveying belt 22 to perform the next step, the gravel is intercepted by the filter screen 18 to be continuously cleaned in the box body 1, and the redundant sand washing water falls into the water tank 20 to be uniformly treated. Because the sand and stone can be stirred at the joint of the upper half shaft 5 and the lower half shaft 4, the fine sand in the sand and stone can be recovered as much as possible.

Wherein, one end of the filter plate 19 is arranged in a downward inclination way, and a gap for fine sand to pass through is arranged between the filter plate 19 and the bottom of the box body 1. It is ensured that the fine sand slides more easily off the filter plate 19.

Wherein, the bottom of the box body 1 is provided with a support 23 downwards, one end of the filter plate 19 is hinged with the support 23, and the other end of the filter plate 19 is connected with the box body 1 through a tension spring 24. When the fine sand accumulates on the filter plate 19 to a certain amount, the weight thereof becomes higher, and the end of the filter plate 19 is pressed down to a lower angle, so that the fine sand falls onto the material transfer belt 22.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
