Description

Technical Field

[0001] This utility model belongs to the field of sand and gravel processing technology, and specifically relates to a sand and gravel separation and cleaning device. Background Technology

[0002] Sand and gravel separation is an important process in industries such as construction, road construction, and concrete production. It aims to separate sand (fine particles) and gravel (coarse particles) from a mixture and wash them to remove impurities. The main function of sand and gravel separation and washing equipment is to separate sand and gravel through physical methods and wash away impurities such as mud and dust attached to the surface of the particles.

[0003] Existing sand and gravel separation and washing devices feed the sand and gravel mixture to be processed into the separation device via a conveyor belt or other means. A vibrating screen is used to vibrate and screen the sand and gravel. During the screening process, a spray system is installed to spray water for rinsing. The sand and gravel are continuously washed by the water flow during vibration, thereby achieving the effect of separation and cleaning. However, in use, because the position of the spray nozzles in the spray system is fixed, the angle of the water flow during sand and gravel separation and cleaning is fixed. This results in a certain limitation on the spray range of the nozzles. In addition, some areas are far from the center of the spray nozzle, resulting in a limited water flow that can be sprayed, which may affect the separation and cleaning effect of the sand and gravel mixture. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a sand and gravel separation and cleaning device. During the sand and gravel separation and cleaning process, the rotating frame where the spray head is located can be rotated to adjust the spraying area of ​​the spray head, thereby enabling more comprehensive and uniform water spraying and cleaning of the sand and gravel during the vibration process, which can effectively improve the separation and cleaning effect of the sand and gravel mixture.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sand and gravel separation and washing device, including a frame, inside which symmetrically distributed guide rails are arranged, and a screening frame is slidably arranged between the guide rails. A screen is arranged inside the screening frame. A support is arranged on the upper surface of the frame, and a rotating rod is rotatably arranged at the upper end of the support. A U-shaped rotating seat is fixedly fitted on the outer arc surface of the rotating rod. Multiple evenly distributed water spray pipes are arranged on the lower surface of the U-shaped rotating seat. Multiple inclined nozzles are arranged at the lower end of each water spray pipe. Each part is equipped with multiple evenly distributed nozzles; the drive assembly includes a drive box II located on the upper end of the support, a U-shaped mounting base located at the bottom of the drive box II, a worm gear rotatably mounted inside the U-shaped mounting base, a worm wheel fixedly sleeved in the middle of the outer arc surface of the rotating rod, the worm wheel meshing with the worm gear, a servo motor mounted on the U-shaped mounting base, the output shaft of the servo motor being fixed to the worm gear via a coupling; multiple evenly distributed support legs are detachably mounted on the lower surface of the frame, and rubber pads are glued and fixed to the lower surface of each support leg.

[0006] As a further improvement of this utility model, a feed hopper is provided at the upper end of the side of the frame away from the screening frame. The feed hopper is installed in conjunction with the screening frame, and a discharge hopper is provided at the discharge port of the screening frame. A drive box is provided on the side of the frame away from the screening frame. A dual-shaft motor is installed inside the drive box. A turntable is fixedly installed on the output shaft of the dual-shaft motor. A linkage rod is rotatably installed on the turntable. The end of the linkage rod away from the turntable is hinged to the screening frame.

[0007] As a further improvement of this utility model, the upper end of the bracket is provided with multiple evenly distributed clamps, and a conveying pipe is provided between the clamps. The water spray pipe is connected to the conveying pipe through a telescopic flexible hose.

[0008] As a further improvement of this utility model, a control panel is provided on the outside of the frame, and the dual-axis motor and servo motor are both electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the conveying pipe is connected to an external water source, which supplies water into the conveying pipe. The water then enters the interior of the spray pipe through a telescopic hose. The spray nozzles, located on the inclined surfaces on both sides of the lower surface and the spray nozzle in the middle of the lower surface, can cover a large area to spray water onto the sand and gravel materials on the screen.

[0011] Secondly, the output shaft of the servo motor drives the worm gear connected to it to rotate back and forth, which in turn causes the rotating rod to drive the water spray pipe to swing back and forth continuously through the U-shaped rotating seat. This drives the water spray pipe and the nozzles 1 and 2 installed on the water spray pipe to spray water from all directions below the bracket for separation and cleaning.

[0012] Thirdly, by continuously reciprocating the screen to screen the sand and gravel, and by driving the water spray pipe and the spray nozzles 1 and 2 on the water spray pipe to swing back and forth, the spraying area of ​​spray nozzles 1 and 2 can be adjusted, so as to spray water to clean the sand and gravel more comprehensively and evenly during the vibration process, which can effectively improve the separation and cleaning effect of the sand and gravel mixture.

[0013] Fourth, the rubber pads on the upper surface of the outriggers allow for flexible contact with the ground, thus avoiding wear caused by long-term rigid contact and extending service life. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4As shown, the device includes a frame 101, inside which symmetrically distributed guide rails 103 are arranged. A screening frame 104 is slidably arranged between the guide rails 103. A screen 105 is arranged inside the screening frame 104. A support 201 is arranged on the upper surface of the frame 101. A rotating rod 202 is rotatably arranged on the upper end of the support 201. A U-shaped rotating seat 203 is fixedly sleeved on the outer arc surface of the rotating rod 202. Multiple evenly distributed water spray pipes 204 are arranged on the lower surface of the U-shaped rotating seat 203. Multiple inclined nozzles 205 are arranged at the lower end of each water spray pipe 204. Multiple evenly distributed nozzles 206 are provided in the center of the surface; a feed hopper 107 is provided on the upper end of the side of the frame 101 away from the screening frame 104. The feed hopper 107 is installed in conjunction with the screening frame 104. The feed hopper 107 is always located above the screening frame 104 to ensure that the material falls into the screening frame 104. A discharge hopper 106 is provided at the discharge port of the screening frame 104; multiple evenly distributed clamps 207 are provided at the upper end of the support 201. A conveying pipe 208 is provided between the clamps 207. The water spray pipe 204 is connected to the conveying pipe 208 through a telescopic flexible hose 209.

[0022] like Figure 1 , 2 As shown, a drive box 108 is provided on the side of the frame 101 away from the screening frame 104. A dual-axis motor 111 is provided inside the drive box 108. A turntable 109 is fixedly provided on the output shaft of the dual-axis motor 111. A linkage rod 110 is rotatably provided on the turntable 109. The end of the linkage rod 110 away from the turntable 109 is hinged to the screening frame 104.

[0023] like Figure 2 , 3 As shown, the drive assembly includes a drive housing 210 mounted on the upper end of the bracket 201. A U-shaped mounting base 212 is provided at the bottom of the drive housing 210. A worm gear 213 is rotatably mounted inside the U-shaped mounting base 212. A worm wheel 211 is fixedly sleeved in the middle of the outer arc surface of the rotating rod 202. The worm wheel 211 is meshed with the worm gear 213. A servo motor 214 is mounted on the U-shaped mounting base 212. The output shaft of the servo motor 214 is fixed to the worm gear 213 by a coupling.

[0024] like Figure 1 , 2 As shown, a control panel 301 is provided on the outside of the frame 101, and the dual-axis motor 111 and the servo motor 214 are electrically connected to the control panel 301.

[0025] When in use, the delivery pipe 208 is connected to an external water source, and the dual-axis motor 111 and servo motor 214 are controlled by the control panel 301.

[0026] The output shaft of the dual-axis motor 111 drives the turntable 109 connected to it to rotate. During the rotation of the turntable 109: the turntable 109 rotates with the linkage rod 110, and the linkage rod 110 rotates with the screening frame 104, so that the turntable 109 drives the screening frame 104 to slide back and forth at a constant speed between the guide rails 103 through the linkage rod 110.

[0027] The output shaft of the servo motor 214 rotates in both directions, causing the worm gear 213 connected to it to rotate in both directions. Through the meshing relationship between the worm gear 213 and the worm wheel 211, the rotating rod 202 where the worm wheel 211 is located rotates in both directions. This causes the rotating rod 202 to drive the water spray pipe 204 to swing back and forth continuously through the U-shaped rotating seat 203. During the swinging process of the water spray pipe 204, water is sprayed evenly and comprehensively onto the screen 105 inside the screening frame 104 through the first nozzle 205 set on the inclined surfaces on both sides of the lower surface and the second nozzle 206 set in the middle of the lower surface.

[0028] The sand and gravel raw materials are poured into the inside of the feed hopper 107 and fall onto the screen 105 set inside the screening frame 104. The sand and gravel are screened by the continuously reciprocating screen 105. The spraying area of ​​the water spray pipe 204 and the spray nozzles 205 and 206 set on the water spray pipe 204 is adjusted by reciprocating the swing, so that the sand and gravel can be sprayed with water more comprehensively and evenly during the vibration process, which can effectively improve the separation and cleaning effect of the sand and gravel mixture.

[0029] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, the lower surface of the frame 101 is detachably equipped with multiple evenly distributed support legs 102, and rubber pads are adhesively fixed to the lower surface of each support leg 102. During use, the rubber pads on the lower surface of the support legs 102 can reduce wear caused by the frame 101's long-term contact with the ground, thus preventing damage to the frame 101.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
