DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] In various embodiments of the present invention, the silty clay and calcium carbonate before screening and crushing by the screening unit and the crushing unit are referred to as materials, and the material after the silty clay and calcium carbonate are crushed and screened by the screening unit and the crushing unit is referred to as a mixture.

[0031] like Figures 1 to 11As shown, an embodiment of the present invention provides a silty clay mixing and improvement processing device, including a frame 1, a stirring unit and a screening unit, wherein the frame 1 is provided with a stirring unit and a screening unit, and the screening unit 2 further includes a screening frame 21 and a screening net 22, and the screening frame 21 is installed on the frame 1 by a rotational fit, and a chute 25 is provided at the end of the screening frame 21, and a screening net 22 is installed in the chute 25 in a sliding fit manner, and the two ends of the screening net 22 pass through the chute 25 and are connected to a transmission plate 26, that is, the transmission plate 26 is located on the outer wall of the screening frame 21, and the outer wall of the screening frame 21 is symmetrically provided with Two return plates 27 are connected to the transmission plate 26 by an elastic member 28. A driving shaft 23 is installed on the screening frame 21 in a rotationally matched manner. Both ends of the driving shaft 23 pass through the screening frame 21 and are respectively installed with a cam 24, and the cam 24 and the transmission plate 26 abut against each other. A first motor 29 is installed on the outer wall of one side of the screening frame 21 through a motor seat. The output end of the first motor 29 is connected to the cam 24 on the same side. Specifically, when it is necessary to drive the screening net 22 to perform reciprocating motion to screen the material, the first motor 29 is started to drive the driving shaft 23 to rotate, and the driving shaft 23 drives the two The cams 24 rotate synchronously, and the cams 24 and the transmission plates 26 abut against each other. During the process of the cam 24 rotating one circle, the protrusions of the two cams 24 synchronously push the two transmission plates 26 to move, and the two transmission plates 26 drive the screening net 22 to slide in the chute 25 toward the end away from the driving shaft 23. At the same time, the transmission plate 26 squeezes the elastic member 28 (the elastic member 28 is an element capable of squeezing and resetting, preferably a spring) to put it in a compressed state. When the cam 24 rotates to the base (that is, the arc surface of the cam 24) and abuts against the transmission plate 26, under the rebound action of the elastic member 28, the transmission plate 26 drives the screening net 22 in the chute 25. The cam 24 slides toward one end close to the driving shaft 23, and can drive the screening mesh 22 to perform a linear reciprocating motion in the chute 25 during one rotation of the cam 24, so that the material performs a reciprocating motion on the screening mesh 22, so that the screening mesh 22 can screen the material, and the smaller material falls from the screening mesh 22 to the ground, and the larger material remains on the screening mesh 22, and the screening mesh 22 transports the larger material to the inside of the screening frame 21 when performing the reciprocating motion (that is, the screening mesh 22 provides power for the material when performing the reciprocating motion, so that the material can enter the inside of the screening frame 21), so that the material can be screened more evenly.

[0032] Furthermore, a plurality of breaking hammers 31 are evenly arranged on the outer wall of the portion of the driving shaft 23 located inside the screening frame 21. Specifically, the end portion of the screening frame 21 connected to the frame 1 is in an arc shape, and the top space of the screening frame 21 is closed (preferably, the top of the screening frame 21 is closed by a flat plate). The positions of the breaking hammers 31 arranged on the driving shaft 23 are staggered with each other. When the driving shaft 23 rotates, the breaking hammers 31 rotate with the driving shaft 23. When the breaking hammers 31 rotate to the bottom end (that is, the breaking hammers 31 rotate to the end close to the screening net 22), the breaking hammers 31 impact the larger materials, and the materials are crushed by the breaking hammers. The rotation of 31 enables the breaker hammer 31 to continuously impact and crush the larger materials, so that the breaker hammer 31 moves the materials from the screening frame 21 to the top thereof when impacting the materials. Under the impact of the side walls and the top of the screening frame 21, the materials are crushed more evenly, so that the smaller materials fall from the screening mesh 22 to the ground, while the larger materials continue to be impacted by the breaker hammer 31 and the screening frame 21 until all the larger materials are crushed. The materials can be crushed continuously, thereby improving the crushing efficiency and quality of the materials. When the cam 24 rotates to push the transmission plate 26 to the end away from the driving shaft 23 (such as Figure 5 As shown), at this time, the breaker hammer 31 on the driving shaft 23 is in a horizontal state (that is, the breaker hammer 31 and the screening net 22 are in a parallel state, as shown in FIG. Figure 4 As shown in the figure, when the breaker hammer 31 rotates to the top (that is, the breaker hammer 31 rotates to the end away from the screening mesh 22), the screening mesh 22 slides in the chute 25 toward the end away from the driving shaft 23, and the screening mesh 22 drives the material to move toward the end away from the driving shaft 23. The screening mesh 22 provides the material with a certain potential energy to move away from the driving shaft 23 (that is, the screening mesh 22 has a tendency to drive the material to move toward the end away from the driving shaft 23). At this time, the breaker hammer 31 rotates toward the bottom end, so that the breaker hammer 31 and the material move in opposite directions (that is, the breaker hammer 31 and the material move in opposite directions). This makes the breaker hammer 31 and the material collide more violently, makes the material crushed more evenly, and improves the material crushing effect.

[0033] Furthermore, the screening mesh 22 is provided with an auxiliary plate 32, the top of the auxiliary plate 32 is mounted on the top of the screening frame 21 in a sliding fit manner, and the bottom of the auxiliary plate 32 is provided with an opening. Specifically, when the material on the screening mesh 22 is being screened, the larger material on the screening mesh 22 enters the interior of the screening frame 21 through the opening of the auxiliary plate 32, and is impacted by the breaker hammer 31. At the same time, the screening mesh 22 drives the auxiliary plate 32 to reciprocate. When the auxiliary plate 32 moves away from the end of the breaker hammer 31, the auxiliary plate 32 blocks the material splashed when the breaker hammer 31 is broken. This prevents the material from flying out of the screening frame 21; when the auxiliary plate 32 moves toward one end of the breaker hammer 31, the auxiliary plate 32 crushes the flying material again (because the auxiliary plate 32 has a certain impact force when it moves toward one end of the breaker hammer 31, when the material hits the auxiliary plate 32, the auxiliary plate 32 will provide a certain impact force to the material, so that the material is impacted and crushed again), so that the material is crushed more evenly, while the traditional auxiliary plate 32 is in a static state. In this embodiment, the auxiliary plate 32 is set to dynamic, so that the auxiliary plate 32 can impact and crush the material again.

[0034] Preferably, a flat groove 34 is provided in the middle of the auxiliary plate 32, and an extrusion plate 35 is installed in the flat groove 34 in a sliding fit manner. A push plate 36 is provided on the side wall of the extrusion plate 35 close to the end of the driving shaft 23. The extrusion plate 35 and the top of the flat groove 34 are connected by a spring 37. Specifically, when the breaker hammer 31 rotates from its top to its bottom, the breaker hammer 31 can hit the side wall of the auxiliary plate 32 (because the distance between the breaker hammer 31 and the auxiliary plate 32 is smaller than that between the breaker hammer 31 and the auxiliary plate 32). The rotation radius is small), so that the breaker hammer 31 impacts and vibrates the auxiliary plate 32 to a certain extent, and the auxiliary plate 32 has a certain vibration effect on the screening net 22, so that the mesh holes blocked in the screening net 22 are vibrated, and the residual materials in the mesh holes fall to the ground. At the same time, the breaker hammer 31 and the propulsion plate 36 abut against each other, so that the breaker hammer 31 drives the propulsion plate 36 to move toward one end of the screening net 22, and the propulsion plate 36 drives the extrusion plate 35 to slide in the flat groove 34 toward one end of the screening net 22, so that the spring The spring 37 is in a stretched state until the extrusion plate 35 is pressed against the screening mesh 22. The extrusion plate 35 squeezes and crushes the material directly below it on the screening mesh 22, thereby improving the crushing effect of the material. The extrusion plate 35 also has a certain impact vibration on the screening mesh 22, further cleaning the residual material in the mesh of the screening mesh 22. After the extrusion plate 35 is pressed against the screening mesh 22, the breaker hammer 31 pushes the auxiliary plate 32 to move away from the end of the driving shaft 23, and the auxiliary plate 32 drives the screening mesh 22 to move. The net 22 slides in the chute 25 toward the end away from the driving shaft 23, so that the screening net 22 squeezes the elastic member 28 through the transmission plate 26, so that the elastic member 28 is in a compressed state. When the breaker 31 and the auxiliary plate 32 are separated from each other, under the rebound action of the elastic member 28, the auxiliary plate 32 slides in the chute toward the driving shaft 23. Under the rebound action of the spring 37, the propulsion plate 36 and the extrusion plate 35 slide toward their top ends in the flat groove 34, facilitating the next collision between the breaker 31 and the propulsion plate 36.

[0035] Furthermore, a baffle 33 is provided in the screening frame 21 near one end of the frame 1 and at the top of the chute 25. Specifically, when the screening mesh 22 screens the material, the screening mesh 22 slides back and forth in the chute 25 at the bottom end of the baffle 33. The larger material remaining on the screening mesh 22 moves from the baffle 33 to the screening frame 21 and will not fall to the ground from the gap between the chute 25 and the screening mesh 22 (that is, when the screening mesh 22 reciprocates and moves to the end away from the breaker hammer 31, there will be a certain gap between the screening mesh 22 and the chute 25). The breaker hammer 31 will impact the material remaining on the baffle 33, so that the material is broken more evenly.

[0036] Furthermore, the end of the frame 1 is rotatably mounted with a straight plate 11 through a positioning shaft, and an arc panel 12 is mounted on the end of the straight plate 11 facing away from the screening net 22, and a square plate 13 is rotatably mounted on the end of the straight plate 11 facing the screening net 22, and a screening frame 21 is mounted on the end of the square plate 13 away from the frame 1. Specifically, when the screening frame 21 and the screening net 22 need to shovel the material on the ground, and when the angle between the screening frame 21 and the screening net 22 and the ground needs to be adjusted, the square plate 13 is driven to rotate at the connection on the straight plate 11, and the straight plate 11 drives the screening frame 21 to rotate, and the screening frame 21 drives the screening net 22 to rotate, so that a certain angle is formed between the screening frame 21 and the screening net 22 and the ground, which facilitates the screening frame 21 and the screening net 22 to scoop up the material, making it easier for the material to enter the screening frame 21 and the screening net 22.

[0037] Furthermore, the square plate 13 is connected to the curved plate 12 at one end close to the frame 1 by a first hydraulic cylinder 14 in a rotationally coordinated manner. Specifically, when the screening frame 21 and the screening net 22 shovel the material, the square plate 13 needs to rotate on the straight plate 11, and the first hydraulic cylinder 14 is started to perform a telescopic operation, so that the square plate 13 rotates on the straight plate 11, and the square plate 13 drives the screening frame 21 to rotate, so that there is a certain angle between the screening frame 21 and the ground, which facilitates the screening frame 21 and the screening net 22 to shovel the material.

[0038] Furthermore, the end of the frame 1 and the straight plate 11 are connected in a rotationally coordinated manner through a second hydraulic cylinder 15. Specifically, when the screening frame 21 and the screening net 22 shovel the material, the straight plate 11 needs to rotate on the frame 1, and the second hydraulic cylinder 15 is started to make it telescope, so that the straight plate 11 rotates on the frame 1. The straight plate 11 drives the screening frame 21 to rotate through the square plate 13, so that there is a certain angle between the screening frame 21 and the ground, which facilitates the screening frame 21 and the screening net 22 to shovel the material.

[0039] Furthermore, the stirring unit 4 includes a slide rail 41 and a sliding plate 42. Two sets of slide rails 41 are symmetrically installed at the front and rear ends of the frame 1. A sliding plate 42 is installed in each set of two slide rails 41 in a sliding fit manner. The two sliding plates 42 are connected by two mutually symmetrical connecting rods 43. The two connecting rods 43 are connected by a plurality of evenly arranged stirring shafts 44 in a rotational fit manner. A stirring roller 45 is installed on the portion of each stirring shaft 44 located between the connecting rods 43. A plurality of stirring tip rods 46 are evenly arranged on the outer wall of each stirring roller 45. The frame 1 is away from the screening A second motor 47 is provided on the sliding plate 42 at one end of the frame 21, and a first gear 48 is installed at the output end of the second motor 47. A second gear is installed on the portion of the stirring shaft 44 located between the stirring roller 45 and the connecting rod 43 on the connecting rod 43 near the end of the second motor 47. The second gear and the first gear 48 are connected by a first chain 410. A third gear 411 is installed on each portion of the stirring shaft 44 away from the second gear and located between the connecting rod 43 and the stirring roller 45. The third gears 411 are connected by a second chain 412. Specifically, when the material is screened on the screening net 22, it falls to After the mixture is formed on the ground, when the mixture needs to be mixed, the sliding plate 42 is driven to slide in the slide rail 41 toward the bottom end of the frame 1, and the sliding plate 42 drives the connecting rod 43 to slide toward the bottom end of the frame 1. The connecting rod 43 drives the stirring shaft 44 and the stirring roller 45 to slide toward the bottom end of the frame 1, so that the stirring roller 45 drives the stirring tip rod 46 to be inserted into the mixture, and the second motor 47 is started to drive the first gear 48 to rotate. The first gear 48 and the second gear (not shown in the figure) are driven by the first chain 410, so that the first gear 48 drives the second gear to rotate through the first chain 410, and the second gear drives the connecting gear connected to it. The stirring shaft 44 rotates, and the stirring shaft 44 drives the third gear 411 to rotate. The third gears 411 are transmitted through the second chain 412, so that each third gear 411 rotates synchronously, and the third gear 411 drives the stirring shaft 44 connected thereto to rotate, and the stirring shaft 44 drives the stirring roller 45 to rotate, and the stirring roller 45 drives the stirring pointed rod 46 to rotate, so that the stirring pointed rod 46 mixes the mixture, so that the mixture is stirred more evenly, so that the mixed mixture can be better used as the raw material of the roadbed, so that the surface of the mixture roadbed is smooth and free of wheel marks after compaction, the compaction layer is dense, the compaction degree control is very ideal, and the roadbed deflection test is qualified.

[0040] Furthermore, each of the stirring shafts 44 is provided with an auxiliary roller 413 on the outside of the connecting rod 43, and a plurality of stirring blades 414 are evenly installed on the outer wall of each of the auxiliary rollers 413. Specifically, when the stirring shaft 44 drives the stirring roller 45 to rotate, the stirring roller 45 drives the stirring blades 414 to rotate, so that the stirring blades 414 stir the mixture, so that the stirring blades 414 mix the mixture more evenly, thereby improving the stirring efficiency of the mixture.

[0041] The bottom end of the frame 1 is symmetrically provided with two card plates 16 between the arc panel 12 and the slide rail 41, and a transmission gear 17 is installed between the two card plates 16 in a rotationally matched manner through a transmission shaft. A first latch tooth 18 is provided on the arc surface of the arc panel 12, and a second latch tooth 19 is provided on the side wall of the sliding plate 42 on the frame 1 close to the arc panel 12 close to the transmission gear 17, and the first latch tooth 18 and the second latch tooth 19 are both engaged with the transmission gear 17 for use. Specifically, when the second hydraulic cylinder 15 drives the straight plate 11 to rotate on the frame 1, the straight plate 11 drives the arc panel 12 to rotate a certain angle, and the arc panel 12 drives the transmission gear 17 to rotate through the first latch tooth 18. The transmission gear 17 drives the sliding plate 42 to slide in the slide rail 41 through the second tooth 19, so that the sliding plate 42 drives the stirring tip rod 46 to be inserted into the mixture through the connecting rod 43, the stirring shaft 44 and the stirring roller 45, so that the stirring tip rod 46 and the stirring blade 414 stir the mixture, making the mixture more uniform. The traditional stirring unit 4 needs to be provided with a reciprocating drive member to provide power for the sliding plate 42 to slide in the slide rail 41. In this embodiment, the reciprocating sliding of the sliding plate 42 in the slide rail 41 can be achieved by rotating the arc panel 12 and the straight plate 11 on the frame 1, so that the stirring tip rod 46 and the stirring blade 414 stir the mixture evenly.
