Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of placer gold beneficiation equipment, specifically relating to a left-right swinging flushing device on a placer gold beneficiation sluice. Background Technology
[0002] Traditional placer gold sluices, regardless of whether the bed surface uses gold-adhesive straw or gold-adhesive blanket, are prone to bed surface hardening during production due to their inherent structure. To mitigate this hardening, some equipment employs flushing devices, which, compared to sluices without such devices, do reduce bed surface hardening to some extent. However, these flushing devices operate in a linear reciprocating motion. In areas with nozzles, the nozzles continuously spray back and forth in a fixed position, causing some fine gold particles that haven't yet settled to be agitated and floated to the surface, flowing down with the slurry. Furthermore, the gaps between the nozzles contribute to localized hardening in these areas. Both of these factors lead to significant loss of recoverable material, thus impacting economic efficiency. Utility Model Content
[0003] To address the aforementioned problems, effectively prevent bed caking in mineral processing sluices, improve flushing efficiency, and increase the enrichment ratio and recovery rate of recovered materials, this invention is a left-right swinging flushing device. During the reciprocating flushing process, the path of its spray nozzles is a non-fixed S-shaped path.
[0004] This utility model is an auxiliary device for a placer gold beneficiation sluice, excluding the sluice body, the reciprocating motion drive system, and the water supply system. The technical solution adopted is as follows: including a U-shaped main component, front and rear mounting brackets, a DC planetary gear reducer motor, an eccentric wheel, left and right sliding components, a sliding guide shaft, a single-sided flange bearing, a water pipe, a nozzle, a connecting plate, and a traveling roller.
[0005] The aforementioned left-right swinging flushing device includes a U-shaped component (the length of which can be set according to the width of the chute bed) with front and rear supports installed on it; a planetary gear motor is installed on one of the supports; the planetary gear motor is a DC 24V adjustable speed motor, which can be adjusted to a suitable speed according to actual needs; an eccentric wheel is installed on the shaft of the planetary gear motor, and the eccentric distance of the eccentric wheel is set according to the nozzle spacing distance; a bearing is installed on the eccentric shaft of the eccentric wheel; the bearing is connected to the left and right sliding components; the sliding components are installed on the guide shafts on the left and right sides, and the guide shafts are installed on the front and rear supports; a single-sided flange bearing is installed on the guide shaft, and the single-sided flange bearing is locked on both sides of the sliding component to prevent the sliding component from deviating from its track position; water pipe hangers are installed at both ends of the sliding component; the water pipe hangers are connected to rectangular water pipes (the length of which can be set according to the width of the chute bed); water nozzles are installed at equal intervals on the lower side of the rectangular water pipe, and a circular water pipe is installed on the other side; the circular water pipe is connected to the external water supply system hose.
[0006] The aforementioned left-right swinging flushing device has connecting plates installed on both sides of the U-shaped component. The connecting plates can be connected to an external drive system to drive the left-right swinging flushing device to flush back and forth. The connecting plates are equipped with traveling rollers, which drive the entire flushing device to move back and forth on the top of the chute.
[0007] The beneficial effect of this invention is that the rotational speeds of the left-right swing drive motor and the front-back reciprocating drive motor are disproportionate. This causes the water nozzles of the flushing device to create an S-shaped path with an unfixed position during the back-and-forth motion along the length of the sluice, ultimately ensuring that the water nozzles continuously flush the entire sluice bed surface. This significantly improves the enrichment ratio and recovery rate, extends the ore discharge time, and substantially increases economic benefits. This left-right swing S-shaped path back-and-forth flushing device is an auxiliary device for placer gold beneficiation sluices and is applicable to various sluice-type beneficiation equipment.

[0011] Examples, such as Figure 1As shown: A left-right swinging flushing device includes a U-shaped main body component 1, with connecting plates 13 installed on both sides of the U-shaped main body component 1. The connecting plates 13 can be connected to different types of drive systems. Rollers 14 are installed on the connecting plates 13. Under the action of the drive system, the rollers 14 drive the left-right swinging flushing device to reciprocate back and forth on the top surface of the chute. The top surface of the U-shaped main component 1 is equipped with front and rear brackets 2. A DC adjustable speed 24V planetary gear reducer motor 3 is installed on one side of the front and rear brackets 2. An eccentric wheel 4 is installed on the output shaft of the planetary gear reducer motor 3. A push bearing 5 is installed on the eccentric wheel 4. The push bearing 5 is connected to the left and right sliding components 6. The left and right sliding components 6 are installed on the left and right guide shafts 7. The guide shafts 7 are installed on the front and rear brackets 2. A single-sided flange bearing 8 is installed on the guide shaft 7. The single-sided flange bearing is locked on both sides of the sliding component to prevent the sliding component from deviating from its track position. Water pipe hangers 9 are connected to the left and right ends of the left and right sliding components 6. A rectangular water pipe 10 is connected to the bottom of the water pipe hanger 9. An equidistant spray nozzle 11 is installed on the lower side of the rectangular water pipe 10. A circular water pipe 12 connected to the external water supply system is installed on the other side of the rectangular water pipe 10.
[0012] In operation, the ore dressing sluice equipped with the left-right swinging flushing device described in this utility model uses a DC adjustable-speed planetary gear reducer motor 3 to drive the push bearing 5 on the eccentric wheel 4 to rotate. The bearing 5 pushes the sliding component 6 to slide left and right on its fixed track. Through the hanger 9, the water nozzles 11 on the water supply pipe 10 swing left and right together. At the same time, the sluice's drive system drives the left-right swinging flushing device to reciprocate back and forth along the length of the sluice. This results in the left-right swinging water nozzles 11 traveling in a non-fixed S-shaped curve during their reciprocating motion. As a result, the water nozzles continuously flush the entire sluice bed surface.

Those skilled in the art can make various variations or modifications based on the above description without creative effort. It is neither necessary nor possible to provide an endless description of all embodiments.
