Description

Technical Field

[0001] This utility model relates to the technical field of placer gold beneficiation tools, specifically a new type of gold panning basket. Background Technology

[0002] The gold panning sieve, a traditional tool with a long history, works on the principle of utilizing the significant density difference between gold and other mineral particles. By shaking the sieve in flowing water, the less dense sand and gravel are washed away, thus concentrating the denser gold particles. Existing individual gold panning tools (represented by the sieve) have significant shortcomings in terms of durability, gold recovery efficiency, and ease of use. While modern large-scale equipment is highly efficient, it is not suitable for individual or small-scale operations.

[0003] In response to the aforementioned technologies, the inventors propose a new type of gold panning winnowing basket. Utility Model Content

[0004] To address the aforementioned problems, this application provides a novel gold panning basket, employing the following technical solution:

[0005] A novel gold panning basket includes a basket body, the bottom of which is divided into two functionally distinct areas along its length: a heavy-duty sorting area for initial enrichment and a light-duty sorting area for fine screening; the bottom of the heavy-duty sorting area is provided with a stepped gilding groove, and the bottom of the light-duty sorting area is a smooth groove; multiple lifting holes are provided on the side wall of the basket body.

[0006] By employing the above technical solution, during operation, a large quantity of ore is first placed in the heavy-load sorting zone. A vortex is generated by shaking the gilding troughs (especially the herringbone sluices) to quickly wash away most of the light sand and gravel, achieving initial enrichment of heavy minerals. Subsequently, the enriched material is transferred to a smooth trough in the light-load sorting zone for fine shaking. Due to the smooth bottom of the trough, observation and final separation of gold particles are easy. A lifting hole allows for the connection of ropes, enabling a lever-like, labor-saving operation.

[0007] Furthermore, the ratio of the bottom area of ​​the heavy-load sorting zone to the bottom area of ​​the light-load sorting zone is approximately 6:4.

[0008] Furthermore, the stepped gilding groove includes an inlet groove, a parallel groove, and at least one herringbone chute connected in sequence; the tip of the herringbone chute faces the smooth groove.

[0009] Furthermore, the walls and bottom of the herringbone chute are set at acute angles.

[0010] Furthermore, the wide groove edge of the winnowing basket body is provided with an annular hand grip, and the hand grip is provided with a functional cover at the position corresponding to the user's hand position.

[0011] Furthermore, the lifting holes are symmetrically arranged on the hand-held guards on both sides of the main body of the winnowing basket, and there are at least 4 lifting holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] High sorting efficiency: By setting up functional zones at the bottom of the tanks (gilding tank and smoothing tank), a standardized operation process of "coarse sweeping and fine sorting" is realized, which greatly improves sorting efficiency and gold recovery rate, especially the ability to capture fine gold particles.

[0014] Effortless operation: The unique hoisting hole design supports multiple operation modes such as the spreader pole method. It utilizes the lever principle to transform the local arm force into the whole body force, significantly reducing the labor intensity of long-term work.

[0015] Ingenious structure, portable and practical: The advanced sorting concept of large equipment is miniaturized and integrated into a portable winnowing basket. While maintaining the advantages of traditional tools in terms of low cost and high portability, it greatly improves its core performance, making it particularly suitable for individual gold prospectors and field exploration.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0022] For specific examples, please refer to the following: Figure 1 , Figure 2 , Figure 3 As shown, for reference Figures 1 to 3 This embodiment provides a novel gold panning winnowing basket. The main body 1 of the basket is a shallow trough shape with one end open and three sides enclosed. It is preferably manufactured using high-density polyethylene (HDPE) or ABS engineering plastic through an integrated injection molding process to ensure that the overall structure is sturdy, lightweight, and corrosion-resistant. Figure 1 As shown, the bottom of the trough of the main body 1 is clearly divided into two functionally continuous but structurally distinct areas along its length: a heavy-load sorting area A and a light-load sorting area B. The heavy-load sorting area A occupies approximately 60% of the total area of ​​the trough bottom, while the light-load sorting area B occupies approximately 40%. This "60 / 40" area allocation conforms to the actual process requirements of "large-scale initial sorting and small-scale fine sorting" in gold panning operations. The bottom of the heavy-load sorting area A is not flat, but rather has a complex stepped gilding groove 3 integrally formed within the mold.

[0023] Combination Figure 3 As can be seen from the enlarged detailed view, the gilding groove 3 is a highly efficient composite flow channel system, which extends inward from the end near the opening of the sieve and includes, in sequence:

[0024] Inlet channel 31: As the receiving area for slurry, its channel is relatively wide, which is convenient for receiving a large amount of ore.

[0025] Parallel channel 32: Connected to the inlet channel 31, it consists of multiple parallel shallow channels and mainly serves to stabilize the slurry flow and perform preliminary enrichment.

[0026] The herringbone sluice 33, as the core of this sorting area, is located at the end of the flow channel, with the acute angle of its "V" shape pointing towards the light-load sorting area B. The walls and bottom of these herringbone sluices 33 form an acute angle of 70° to 80°. Its core function is to effectively generate controllable eddies and turbulence when the sluice sways left and right in the water. This powerfully washes away light gravel while simultaneously using the dead angles created by the herringbone structure to perfectly trap fine-grained gold and other heavy minerals, greatly reducing the "gold runaway" phenomenon.

[0027] The bottom of the light-load sorting zone B is a smooth plane, namely the smooth trough 2. This area has a smooth surface without any obstructions. Its design purpose is that after the small amount of heavy sand enriched in the initial sorting is transferred to this area, the operator can gently agitate it in calm water. Due to the smooth bottom of the trough, the distribution of gold particles and the remaining small amount of black heavy sand such as magnetite is clearly visible, making it easy to observe and perform the final fine separation, thus facilitating the picking out of gold particles. At the wide edge of the winnowing basket body 1, there is an integrally formed, upward-curving annular hand grip 4. This grip not only enhances the overall structural strength but also, in the positions corresponding to the user's two hands (usually the middle of the sides of the winnowing basket), nested with anti-slip rubber sleeves (not shown in the diagram), significantly improves the comfort and safety of holding the basket.

[0028] Specifically, four lifting holes 11 are symmetrically arranged on the hand-held edge guard 4. These lifting holes 11 are not simple round holes; their walls are thickened and reinforced to withstand repeated friction and pulling of the rope. Figure 1 As shown, the two lifting holes 11 on each side are spaced a certain distance apart. This design ensures that the main body 1 of the winnowing basket remains balanced and stable during subsequent use, when ropes are connected and "carrying pole" operations are performed, preventing it from tipping over. Furthermore, reference numeral "6" in the attached drawing indicates a possible reinforcing rib structure at the bottom of the main body 1. Based on the drawing, these reinforcing ribs effectively prevent deformation of the bottom of the trough during load-bearing and shaking, further improving the product's durability. The method of use of this utility model is briefly described below:

[0029] 1. Preliminary selection stage: Place the ore sand in the heavy-duty sorting zone A, immerse the winnowing basket in water, lift it up and tilt it slightly. The operator holds the hand-held guard 4 with both hands and shakes it vigorously from side to side. The ore sand is efficiently sorted in the gilding tank 3. Most of the sand and gravel is carried away by the water flow, and heavy minerals are enriched at the bottom of the tank.

[0030] 2. Fine selection stage: Transfer the initially selected concentrate to the smooth trough 2 in the light-load sorting zone B. Hold the sieve level and gently shake it back and forth in water until the gold particles are clearly visible on the smooth bottom of the trough.

[0031] 3. Labor-saving mode: When long-term operation or handling large quantities of materials is required, two ropes can be tied to the two lifting holes 11 on the same side, and then the other end of the ropes can be fixed to a base or a lightweight metal rod. The operator can lift the device like carrying a shoulder pole and swing the scoop in the water by swinging their body. This method utilizes the lever principle to greatly save arm strength.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
