Description

Technical Field

[0001] The invention relates to the technical field of stone washing and mud removal, and more specifically to a stone washing and mud removal device for highway roadbed construction. Background Art

[0002] During the roadbed construction of highway projects, materials such as stones are needed. However, due to the large amount of dirt on the surface of the stones during the mining and transportation process, in order to ensure the quality of paving, the dirt on the surface of the stones needs to be removed before paving. The existing stone washing and mud removal devices for highway roadbed construction include drum-type stone washing and mud removal machines. Stones with mud and stone powder are fed into the rotating drum through the feed port, and the drum is driven to rotate by the reduction rotation mechanism. The materials in the drum are continuously lifted and thrown down by the rubber lining, rolling, rubbing and colliding in the drum, thereby removing the dirt and impurities attached to the surface. After multiple cycles of cleaning, the clean stones are discharged from the discharge end of the drum.

[0003] In the process of stone washing and mud removal, the transportation of stones in the drum depends on the rotation of the inclined drum. Therefore, under the premise of continuously putting stones containing mud balls and stone powder into the rotating drum, the rotation speed of the drum directly affects the efficiency of stone washing and mud removal, and the length of the drum affects the time of stone tumbling, friction and collision in the drum, thereby directly affecting the effect of stone washing and mud removal. Stones from different sources require different cleaning times. However, the existing drum-type stone washing and mud removal machine has a single structure and a fixed drum length, resulting in a single stone cleaning effect. It is not suitable for stone washing and mud removal from different sources and has a single function. In view of this, we propose a stone washing and mud removal device for highway roadbed construction. Summary of the invention

[0017] The beneficial effects of the present invention are:

[0018] 1. The present invention, through the structural design of the drum mechanism and the planetary transmission mechanism, can drive the inner cylinder and the connecting ring to form differential rotation according to the content of mud balls and stone powder on stones from different sources through the differential rotation state of the two rotating ends of the planetary transmission mechanism, so that the ball block A moves in the threaded guide groove, so that the connecting ring drives the outer cylinder to move relative to the inner cylinder, and adjusts the distance of the cleaning chamber formed by the inner cylinder and the outer cylinder to adjust the cleaning distance and cleaning time of the stone to ensure the cleaning effect of the stone. The stone to be washed and demudden is fed into the drum mechanism through the spiral feeding mechanism, and the inner cylinder and the outer cylinder are driven to rotate as a whole to clean the stone through the overall rotation state of the two rotating ends of the planetary transmission mechanism. The cleaned stone is output from the tail end of the filter cylinder, and part of the crushed stone, mud balls and stone powder leak out from the gap of the filter cylinder to complete the cleaning of the stone. The present invention can be applied to the stone washing and demudification of stones from different sources, has high functionality, and solves the technical problem of the single function of the current stone washing and demudification device for highway roadbed construction.

[0019] 2. The present invention also designs the structure of the protrusion and the protrusion assembly so that when the inner cylinder and the outer cylinder rotate as a whole, the protrusion and the protrusion assembly assist the falling, rolling, friction and collision of the stones, thereby improving the efficiency of removing the dirt and impurities attached to the surface, and by further setting the protrusion assembly, the outer cylinder is relatively displaced relative to the inner cylinder. If the protrusion assembly moves from the inner cylinder to the outside of the inner cylinder as the outer cylinder moves, under the elastic force of the elastic spring, the slider A slides relative to the slide groove A, and the slider B slides relative to the slide groove B, causing the protrusion assembly to move from the inner cylinder to the outside of the inner cylinder. Fig. 9 The status shown changes to Fig.10 The raised state shown in the figure assists the falling, rolling, friction and collision of the stone after entering the outer cylinder. If the raised component moves from the outside of the inner cylinder to the inside of the inner cylinder as the outer cylinder moves, the inclined guide surface of the slider A contacts the rear end of the outer cylinder, so that the slider A slides along the eccentric direction relative to the slide groove A, and the elastic spring is compressed. Then the slider B contacts the rear end of the outer cylinder, and the slider B slides along the eccentric direction relative to the slide groove B, and the elastic spring is compressed. The raised component moves from Fig.10 The status shown changes to Fig. 9 In the raised state shown, the raised assembly is automatically received into the inner cylinder without manual adjustment, so that the distance of the cleaning chamber formed by the inner cylinder and the outer cylinder is easy to adjust. In actual use, when cleaning stones, the falling and impact of stones will easily damage the elasticity of the elastic spring, and the raised assembly at the tail end of the outer cylinder is used more times, and the elasticity of the corresponding elastic spring is more easily damaged. When replacing the raised assembly, you only need to remove the bolts on the mounting plate, remove the raised assembly with damaged elasticity, slide the slider B of the new raised assembly into the slide groove B, and use the bolts again to fix the mounting plate and the mounting groove.

[0020] 3. The present invention further designs the threaded guide groove so that when the ball block A moves in a part of the threaded groove, the connecting ring drives the outer cylinder to move relative to the inner cylinder, and the displacement distance of the ball block A in the part of the threaded groove is equal to the gap distance between the two adjacent groups of mounting grooves, which facilitates the ejection of the protrusion assembly after the outer cylinder is displaced relative to the inner cylinder by a corresponding distance. When the ball block A moves on the arc groove A or the arc groove B, the position of the outer cylinder relative to the inner cylinder remains stationary, which facilitates the adjustment of the cleaning cavity distance formed by the inner cylinder and the outer cylinder, and also facilitates the adjustment of the planetary transmission mechanism from the differential rotation state to the overall rotation state.

[0021] 4. The present invention further designs the threaded guide groove so that when the ball block A moves in a part of the threaded groove, the connecting ring drives the outer cylinder to move relative to the inner cylinder, and the displacement distance of the ball block A in the part of the threaded groove is equal to the gap distance between two adjacent groups of mounting grooves, which facilitates the ejection of the protrusion assembly after the outer cylinder is displaced relative to the inner cylinder by a corresponding distance. When the ball block A moves on the arc groove A or the arc groove B, the position of the outer cylinder relative to the inner cylinder remains stationary, which facilitates the adjustment of the distance of the cleaning chamber formed by the inner cylinder and the outer cylinder.

The present invention drives the inner cylinder 41 and the connecting ring 44 to form a differential rotation through the differential rotation state of the two rotating ends of the planetary transmission mechanism 6, so that the ball block A45 moves in the thread guide groove 42, so that the connecting ring 44 drives the outer cylinder 43 to move relative to the inner cylinder 41, adjusts the cleaning cavity distance formed by the inner cylinder 41 and the outer cylinder 43, so as to adjust the cleaning distance and cleaning time of the stone, ensure the cleaning effect of the stone, and feeds the stone to be washed and desilted into the drum mechanism 4 through the spiral feeding mechanism 5, and drives the inner cylinder 41 and the outer cylinder 43 to rotate as a whole through the overall rotation state of the two rotating ends of the planetary transmission mechanism 6.

[0057] The outer surface of the outer cylinder 43 is provided with a plurality of mounting grooves 431 in a linear and equidistant structure, and each group of mounting grooves 431 includes a plurality of mounting grooves 431 arranged in a circular and equidistant structure, and a slide groove A432 is provided on the mounting groove 431, and a protrusion assembly 48 is provided on the mounting groove 431. In the present invention, a plurality of protrusions 411 are evenly fixed on the inner surface of the inner cylinder 41, and a protrusion assembly 48 is provided on the mounting groove 431, so that when the inner cylinder 41 and the outer cylinder 43 rotate as a whole, the protrusions 411 and the protrusion assembly 48 assist the throwing, rolling, friction and collision of the stones, thereby improving the efficiency of removing the dirt and impurities attached to the surface.

[0058] In an embodiment of the present invention, the protrusion assembly 48 includes a mounting plate 481 and a slider A482. The mounting plate 481 is detachably connected to the mounting groove 431 by a plurality of bolts. The mounting plate 481 is adapted to the surface shape of the outer cylinder 43.

The swivel C634 is swivel-connected to the slide groove C626. A swivel D630 is movably connected, and the swivel D630 is movably connected to the rotating groove A623. The tail end of the swivel D630 is fixed with a plurality of plug-in blocks A635 in a ring-shaped equidistant structure. The plurality of plug-in blocks A635 are respectively slidably connected to the plurality of plug-in grooves A617. A plug-in block B636 is fixed at the tail end of the plug-in block A635. The plug-in block B636 is movably connected to the rotating groove B624. The two ends of the plug-in block B636 are respectively plugged into and matched with the plug-in groove B618 and the plug-in groove C625.

[0066] The present invention adopts the mechanism design of the planetary transmission mechanism 6. When the motor 631 is controlled to rotate by an external control mechanism, the screw rod 632 rotates, and the slip ring 633 slides on the slide groove C626, so that the rotating ring D630 slides relative to the rotating groove A623, the plug-in block B636 slides relative to the rotating groove B624, and the plug-in block A635 slides relative to the plug-in groove A617. Fig.15 As shown, when the plug-in block B636 is plugged into the plug-in slot B618, the plug-in block B636 is disengaged from the plug-in slot C625. At this time, the gear ring A611 and the rotating ring X613 cannot rotate relative to each other. Therefore, the gear 616 cannot rotate by itself, so that the rotation of the gear ring B612 can drive the entire planetary assembly 61 to rotate, so that the rotating ring D630 rotates relative to the rotating ring C634. Fig.16As shown, when the plug-in block B636 is disengaged from the plug-in slot B618, the plug-in block B636 is plugged into the plug-in slot C625. At this time, the swivel D630 cannot rotate, making the gear ring A611 unable to rotate. At this time, the rotation of the gear ring B612 can drive the gear 616 to perform planetary revolution, thereby making the swivel Y614 rotate differentially relative to the gear ring B612, thereby making the connecting ring 44 drive the outer cylinder 43 to move relative to the inner cylinder 41. Among them, since the protrusion assembly 48 is used to assist the falling, rolling, friction and impact of stones, the elastic spring 486 of the present invention has a high elasticity, so that the protrusion assembly 48 has a large resistance when it moves from the outside of the inner cylinder 41 to the inside of the inner cylinder 41 as the outer cylinder 43 moves. The differential rotation of the swivel Y614 relative to the gear ring B612 can further reduce the rotation load of the deceleration rotation assembly 31.

[0067] Working principle: This embodiment provides a stone washing and mud removal device for highway roadbed construction. When in use, the cleaning time required is evaluated according to the specific conditions of the stones to be processed, and the distance of the cleaning chamber formed by the inner cylinder 41 and the outer cylinder 43 is adjusted;

[0068] The motor 631 is controlled to rotate by an external control mechanism, the screw 632 rotates, the slip ring 633 slides on the slide groove C626, and the plug block B636 slides relative to the rotating groove B624, so that the plug block B636 is disengaged from the plug groove B618, and the plug block B636 is plugged into the plug groove C625. At this time, the rotating ring D630 cannot rotate, so that the gear ring A611 cannot rotate. At this time, the gear ring B612 is driven to rotate through the reduction rotation component 31, and the gear 616 performs a planetary revolution motion, so that the rotating ring Y614 rotates differentially relative to the gear ring B612, so that the connecting ring 44 drives the outer cylinder 43 relative to the inner cylinder 41. After the gear ring 612 is moved to an appropriate length, the gear ring B612 continues to rotate, so that the ball block A45 moves on the arc groove A422, and the outer cylinder 43 remains stationary relative to the inner cylinder 41 until the position of the plug-in block B636 is aligned with the plug-in slot B618, and the deceleration rotation component 31 stops working; the motor 631 is controlled to rotate by an external control mechanism, the plug-in block B636 is plugged into the plug-in slot B618, and the plug-in block B636 is disengaged from the plug-in slot C625. At this time, the gear ring A611 and the rotating ring X613 cannot rotate relative to each other, so the gear 616 cannot rotate by itself, so that the rotation of the gear ring B612 can drive the entire planetary component 61 to rotate;

[0069] The gear ring B612 is driven to rotate by the reduction rotation component 31, so that the inner cylinder 41 and the outer cylinder 43 rotate as a whole, and the stones to be washed and demudden are fed into the drum mechanism 4 through the spiral feeding mechanism 5. The rotating inner cylinder 41 and the outer cylinder 43 throw, roll, rub and impact the stones for cleaning.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
