For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example 1

[0031] like Figure 1-6As shown, a sand washing device for sand and stone processing includes two driven shafts 10, which are sleeved on a rotating shaft 21. The driven shaft 10 and the rotating shaft 21 are rotatably matched, and the two driven shafts 10 are connected by a conveyor belt 4. Chains 9 are fixedly provided on the left and right edges of the conveyor belt 4. Driven gears 12 are sleeved on the left and right ends of the driven shaft 10. The driven gears 12 are fixedly connected to the driven shaft 10, and the driven gears 12 are meshed with the chains 9. The chains 9 are also connected to a driving mechanism, and the driving mechanism is used to drive the chains 9 to move; a water pipe 2 is arranged above the conveyor belt 4, the water pipe 2 is connected to an external water source, and a plurality of sprinkler heads 3 are installed at the bottom of the water pipe 2.

[0032] The driving mechanism drives the chain 9 to move, and the chain 9 drives the conveyor belt 4 to rotate cyclically. The length of the conveyor belt 4 can be set to 10 meters, 20 meters, or 30 meters as needed.

[0033] The sand and gravel to be cleaned are continuously put onto the conveyor belt 4 , and when the sand and gravel move below the spray head 3 , the sand and gravel are cleaned by the water sprayed from the spray head 3 .

[0034] Example 2

[0035] like Figure 1-6 As shown, when other parts are the same as those of Example 1, the difference between this embodiment and Example 1 is that: both left and right sides of the driven shaft 10 are provided with limit plates 11, the limit plates 11 are sleeved on the rotating shaft 21, and the limit plates 11 are fixedly connected to the rotating shaft 21. Both left and right ends of the rotating shaft 21 are provided with first brackets 5, the upper end of the first bracket 5 is fixedly connected to the rotating shaft 21, and the lower end of the first bracket 5 is fixedly connected to the ground. A plurality of suspension rods 1 are arranged above the water pipe 2, the lower end of the suspension rod 1 is fixedly connected to the water pipe 2, and the upper end of the suspension rod 1 is fixedly connected to the roof. A plurality of drainage holes 22 are provided on the conveyor belt 4.

[0036] The driving mechanism includes a motor 15, a base 18 is provided below the motor 15, the top of the base 18 is fixedly connected to the motor 15, the bottom of the base 18 is fixedly connected to the ground, the power output end of the motor 15 is fixedly connected to the driving shaft 17, the end of the driving shaft 17 close to the motor 15 is sleeved with a driving gear 16, the driving gear 16 is fixedly connected to the driving shaft 17, and the driving gear 16 is meshed with the chain 9. The driving mechanism also includes a water tank 6, the water tank 6 is in the shape of a boat, the conveyor belt 4 surrounds the water tank 6, a mud discharge pipe 7 is fixedly provided at the bottom of the water tank 6, and a plurality of water inlet holes 13 are opened on the side of the mud discharge pipe 7 close to the motor 15, an auger blade 8 is fixedly provided on the driving shaft 17, the auger blade 8 and the driving shaft 17 are both located in the mud discharge pipe 7, a mud discharge cover 19 is fixedly provided at the end of the mud discharge pipe 7 away from the motor 15, the mud discharge cover 19 is funnel-shaped, and a plurality of water seepage holes are opened at the bottom of the mud discharge pipe 7. A plurality of second brackets 14 are fixedly provided at the edge of the water tank 6, and the second brackets 14 are fixedly connected to the ground.

[0037] The motor 15 drives the driving gear 16 to rotate, the driving gear 16 drives the chain 9 to rotate, and the chain 9 drives the conveyor belt 4 to rotate cyclically.

[0038] When the sand and gravel are cleaned by the water sprayed from the sprinkler head 3, the mud in the sand and gravel is entrained by the water to form muddy water, which flows downward through the drainage hole 22 on the conveyor belt 4, and then enters the water tank 6, and enters the mud discharge pipe 7 through the water inlet hole 13 on the mud discharge pipe 7. The water in the muddy water entering the mud discharge pipe 7 flows out through the seepage hole at the bottom of the mud discharge pipe 7, and the sludge is retained in the mud discharge pipe 7.

[0039] When the motor 15 drives the driving gear 16 to rotate, it drives the driving shaft 17 and the auger blades 8 to rotate synchronously. The auger blades 8 drive the sludge in the mud discharge pipe 7 to move toward the mud discharge cover 19. Since the outlet of the funnel-shaped mud discharge cover is much smaller than the mud discharge pipe 7, the sludge accumulates on the side of the mud discharge pipe 7 close to the mud discharge cover 19.

[0040] When the sand and gravel passing under the spray head 3 are dirty and have more sludge, more sludge accumulates on the side of the sludge discharge pipe 7 close to the sludge discharge cover 19, increasing the sludge density there, thereby limiting the rotation of the auger blades 8, slowing down the rotation of the auger blades 8, thereby slowing down the speed of the driving gear 16, and thus slowing down the speed of the chain 9 and the conveyor belt 4, increasing the time it takes for the sand and gravel to be cleaned by the spray head 3.

[0041] When the sand and gravel passing under the spray head 3 are relatively clean and have less sludge, less sludge accumulates on the side of the sludge discharge pipe 7 close to the sludge discharge cover 19, reducing the sludge density there, thereby making the auger blade 8 rotate faster, thereby making the driving gear 16 rotate faster, thereby making the chain 9 and the conveyor belt 4 rotate faster, reducing the time for the sand and gravel to be cleaned by the spray head 3, and quickly cleaning the sand and gravel.

[0042] The present invention automatically adjusts the rotation speed of the conveyor belt 4. When there is more sludge on the sand and gravel, the rotation speed of the conveyor belt 4 slows down, allowing more time to clean the sand and gravel. When there is less sludge, the rotation speed of the conveyor belt 4 slows down, allowing quick cleaning, thereby effectively improving the cleaning efficiency and effect.

[0043] Example 3

[0044] like Figure 1-6 As shown, when other parts are the same as those of Example 2, the difference between this embodiment and Example 2 is that a sludge collecting bucket 20 is provided below the sludge discharge cover 19. By providing the sludge collecting bucket 20, the sludge discharged through the sludge discharge cover 19 can be collected.

[0045] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
