[0022] Example: A preliminary washing device for precious metal recovery, as Figures 1 - 3As shown in the figure, it includes a collection box 1, a link box 2, a placement plate 3, a sliding rod 4, a fixed frame 5, a link frame 6, a water spray box 7, a first fixing block 8, a second fixing block 81, a water pipe 9, a driving motor 10, a third fixing block 11, a first rotating rod 12, a first bevel gear 13 and a gear ring 131. The collection box 1 is the installation carrier for parts. The outer circle of the collection box 1 is fixedly connected with the link box 2. The inner circle of the collection box 1 is rotatably provided with a placement plate 3. Square drain grooves are evenly spaced on the placement plate 3. The collection box 1 is slidably provided with sliding rods 4 symmetrically before and after. A fixed frame 5 is fixedly connected between the upper parts of the sliding rods 4. The inner circle of the fixed frame 5 is rotatably provided with a water spray box 7. Spray holes are evenly spaced on the lower side of the water spray box 7. The upper part of the water spray box 7 is communicated with a link frame 6. The upper side of the fixed frame 5 is fixedly connected with a first fixing block 8. The water pipe 9 is connected in an S shape between the first fixing block 8 and the second fixing block 81. The upper end of the water pipe 9 is detachably connected to the link frame 6. The water pipe 9 is located between the left sides of the two sliding rods 4. The water pipe 9 is composed of two elbows, a straight pipe and a folding pipe. A driving motor 10 is installed on one side of the upper part of the fixed frame 5. The driving motor 10 is located between the right sides of the two sliding rods 4. A third fixing block 11 is fixedly connected to one side of the upper part of the fixed frame 5. The third fixing block 11 is located below the driving motor 10. A first rotating rod 12 is fixedly connected to the third fixing block 11. A first bevel gear 13 is fixedly connected to the upper part of the first rotating rod 12. The lower end of the output shaft of the driving motor 10 is connected to the first bevel gear 13. The outer circle of the upper part of the water spray box 7 is evenly spaced and connected with a gear ring 131. The gear ring 131 meshes with the first bevel gear 13. The water source is connected to the water spray box 7 through the water pipe 9 and is washed onto the surface of the precious metal through the spray holes on the water spray box 7. The driving motor 10 is started to drive the first bevel gear 13 to rotate and cooperate with the gear ring 131, so that the water in the water spray box 7 is quickly sprinkled out to wash the surface of the precious metal.

[0023] As Figures 4 - 5 shown, it further includes a return spring 31. A return spring 31 is wound between the left end of the placement plate 3 and the collection box 1. The return spring 31 is located outside the collection box 1. A fourth fixing block 111 is fixedly connected to one side of the upper part of the fixed frame 5. The fourth fixing block 111 is located below the first rotating rod 12. A second rotating rod 121 is rotatably provided on the fourth fixing block 111. Limit blocks are symmetrically arranged on the left and right sides of the second rotating rod 121. A second bevel gear 14 is fixedly connected to the bottom end of the second rotating rod 121. A missing gear 141 is fixedly connected to the right end of the placement plate 3. The second bevel gear 14 meshes with the missing gear 141. When the first bevel gear 13 rotates, it drives the cooperation of the missing gear 14 and the second bevel gear 141, so that the placement plate 3 rotates regularly, making the precious metal vibrate on the placement plate, and the water on its surface flows downward with impurities and gradually dries.

[0024] As Figure 1 shown, it further includes a lid 15. The lid 15 is detachably provided on the outer circle of the link box 2.

[0025] When the device needs to be used, the staff moves the fixed frame 5 upward. The fixed frame 5 drives the sliding rod 4, the link frame 6, the water spraying frame 7, the first fixing block 8, the water pipe 9, the driving motor 10, the third fixing block 11, the first rotating rod 12, the first bevel gear 13 and the gear ring 131 to move downward. The folding pipe in the middle of the water pipe 9 unfolds. Put the precious metal on the placing plate 3, release the fixed frame 5, and the fixed frame 5 moves downward under the action of gravity. The fixed frame 5 drives the above-mentioned components to move downward and reset. The collection box 1 contacts the fixed frame 5 again. Connect the water pipe 9 to a container filled with water source. Water enters the link frame 6 through the water pipe 9 and then falls onto the surface of the precious metal through the spraying holes on the water spraying frame 7 for washing. During the washing process, by starting the driving motor 10, the output shaft of the driving motor 10 rotates to drive the first bevel gear 13 to rotate. Through the meshing transmission of the first bevel gear 13 and the gear ring 131, the water spraying frame 7 is driven to rotate, so that the water on the water spraying frame 7 is quickly sprinkled out to wash the precious metal, and the washing effect is better. At the same time, the first bevel gear 13 drives the missing gear 141 to rotate through the second rotating rod 121. The gear on the missing gear 141 meshes with the second bevel gear 14, thereby driving the placing plate 3 to rotate, and the return spring 31 deforms. When the gear on the missing gear 141 is disengaged from the second bevel gear 14, the return spring 31 returns to its original state, and the placing plate 3 resets under the elastic force of the return spring 31. Repeating this process makes the precious metal vibrate regularly on the placing plate 3, so that the water on the surface of the precious metal with impurities falls into the collection box 1 through the drain grooves on the placing plate 3, and the working efficiency is relatively high. After the washing operation is completed, turn off the driving motor 10 to stop the rotation of the water spraying frame 7 and the placing plate 3. Then operate according to the above content to open the fixed frame 5, take out the washed precious metal from the collection box 1. Finally, close the fixed frame 5, remove the lid 15 from the link frame 2, drain the water in the collection box 1, and then install the lid 15 back to its original position.
