[0018] Advantages of the present invention:

[0019] (1) The paver for preventing segregation of the cement stabilized aggregate base of the present invention is provided with three anti-segregation structures: a turning and mixing mechanism, a stirring mechanism, and a conversion mechanism. Among them, the turning and mixing mechanism can turn the bottom cement upward, the stirring mechanism can fully stir the cement, and the conversion mechanism facilitates the position conversion of the cement at the bottom. All three can effectively mix the components of the cement, making the cohesion between the cement components uniform, avoiding the phenomenon of coarse aggregate sinking and mortar floating, and thus making the cement stable and preventing the occurrence of poor base segregation, achieving a good anti-segregation effect.

[0020] (2) Whether it is during the paving operation or not, since the loading box is connected to the transition box and the inclined end of the inclined plate faces the connection port of the loading box and the transition box, under the action of gravity, the cement inside the transition box is always full. When a part of the cement flows out from the feeding nozzle, another part of the cement is still conveyed to the hopper by the screw conveyor mechanism to repeat the cyclic action of the turning and mixing mechanism, the stirring mechanism, and the conversion mechanism. The triple interference makes the cement always maintain an efficient cyclic movement state, which can further improve the anti-segregation effect of the cement.

[0021] (3) A single double-shaft motor can simultaneously provide power sources for the conversion mechanism, the screw conveyor mechanism, and the turning and mixing mechanism. On the one hand, it can save equipment costs, and on the other hand, it can make the connection between various parts of the mechanism more compact, thus making the structure more stable.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figure 1-8 As shown, the present invention is a paver based on preventing segregation of the cement stabilized macadam base course, including the main body 1 of the machine and the carriage 2 installed on the main body 1 of the machine; the carriage 2 is composed of a loading box 21, an inclined plate 22, a transition box 23, a blanking nozzle 24 and a solenoid valve 25. The transition box 23 is fixedly connected to one end of the loading box 21 away from the main body 1 of the machine and is connected to the main body 1 of the machine. The inclined plate 22 is arranged inside the loading box 21, and the downward inclined end is connected to the transition box 23; the blanking nozzle 24 is installed on the lower side of the transition box 23 and extends through the vehicle plate of the main body 1 of the machine to the lower side of the vehicle plate;

[0034] The solenoid valve 25 is installed in the blanking nozzle 24; one end of the upper side of the loading box 21 near the transition box 23 is provided with a box top, a stirring mechanism 8 is arranged below the box top, and a material box 4 is arranged on the upper side. A spiral conveying mechanism 9 is arranged between the transition box 23 and the material box 4; a conversion mechanism 5 is arranged inside the material box 4, and a stirring mechanism 7 extending into the loading box 21 is arranged on the upper side of the material box 4; a pipeline leading to the loading box 21 is arranged at the lower end of the side wall of the material box 4, and a valve is arranged in the pipeline.

[0035] Specifically, when using the above-mentioned paver for paving, first inject a sufficient amount of cement into the loading box 21. Since the loading box 21 is communicated with the transition box 23, then, under the action of gravity, the cement will flow into the transition box 23 along the inclined plate 22, making the transition box 23 full of cement; Subsequently, the spiral conveying mechanism 9, the conversion mechanism 5, the stirring mechanism 7 and the mixing mechanism 8 are all put into working state. Then the cement in the loading box 21 will flow into the transition box 23 after the action of the stirring mechanism 7 and the mixing mechanism 8, and then enter the material box 4 through the transmission of the spiral conveying mechanism 9 from the transition box 23. When there is a certain amount of cement in the material box 4, the conversion mechanism 5 will act on the cement, and the cement after the action of the conversion mechanism 5 will flow back into the loading box 21 through the pipeline to repeat the above process, realizing the cyclic action of the stirring mechanism 7, the mixing mechanism 8 and the conversion mechanism 5 on the cement, so that the cement is always in a moving state;

[0036] It should be noted that when performing the cement leveling operation, only need to open the solenoid valve 25 and keep the main body 1 of the machine running at a constant speed on the road surface. The cement that has undergone the cyclic action of the stirring mechanism 7, the mixing mechanism 8 and the conversion mechanism 5 will flow to the ground through the blanking nozzle 24 in the transition box 23 and be rolled flat by the subsequent flattening roller 3, that is, the cement paving is completed; At the same time, since the loading box 21 is communicated with the transition box 23 and the lower inclined end of the inclined plate 22 faces the communication port of the loading box 21 and the transition box 23, then, under the action of gravity, the cement inside the transition box 23 is always full. When a part of the cement flows out from the blanking nozzle 24, another part of the cement is still conveyed to the material box 4 by the spiral conveying mechanism 9 to repeat the previous cyclic action process;

[0037] Generally speaking, whether it is in the paving operation period or not, the stirring mechanism 7, the mixing mechanism 8 and the conversion mechanism 5 can all perform cyclic action on the cement, making the cement always maintain a high-efficiency moving state, so that the cohesion between the cement components is uniform, avoiding the phenomenon of coarse aggregate sinking and mortar floating, and further making the cement stable and not showing the bad situation of base segregation.

[0038] Furthermore, the conversion mechanism 5 is composed of a dual-axis motor 51, a rotating shaft 52, a connecting rod 53, a metal ball 54, and a conversion plate 55. The dual-axis motor 51 is fixedly installed at the center of the upper side of the feed bin 4. The rotating shaft 52 is fixedly connected to the lower output end of the dual-axis motor 51 and movably passes through the top wall of the feed bin 4 and extends to the lower part inside the feed bin 4. One end of the connecting rod 53 is movably connected to the side wall of the rotating shaft 52, and the other end is fixedly connected to the metal ball 54. The conversion plate 55 is installed on the metal ball 54.

[0039] In a further embodiment, each of the connecting rod 53, the metal ball 54, and the conversion plate 55 constitutes a swinging member. The metal ball 54 is made of a high-quality metal material. A number of layers of the swinging members are longitudinally arranged on the rotating shaft 52. Each layer includes a number of groups of swinging members. The number of groups of the swinging members is evenly distributed and movably connected to the shaft wall of the rotating shaft 52 in the horizontal direction.

[0040] Preferably, in the present invention, there are two layers of the swinging members, the number of swinging members in each layer is four, and the metal ball 54 is made of metal iron with a coating. In practical applications, the size and number of the swinging members can be reasonably determined according to the size of the feed bin 4.

[0041] Specifically, when the dual-axis motor 51 is started, the conversion mechanism 5 enters the working state. The dual-axis motor 51 drives the rotating shaft 52 to rotate, and the rotating shaft 52 drives the swinging members to move. The detailed process is as follows: The initial state of the swinging member is that the conversion plate 55 thereof hangs downwards. When the rotating shaft 52 rotates, it will drive each group of swinging members to rotate around the rotating shaft 52. Under the action of centrifugal force, the swinging members will overcome the downward resistance of the cement and gradually move from the initial rotation below to the rotation above until they reach the horizontal height of the connection between the connecting rod 53 and the rotating shaft 52. During this period, the swinging members not only stir the cement in the feed bin 4, but also the cement below the feed bin 4 will be carried to the upper part of the feed bin 4 by the conversion plate 55, realizing the conversion of the position of the bottom cement.

[0042] When the switch of the dual-axis motor 51 is turned off, the rotating shaft 52 will stop rotating, and the swinging members will gradually stop moving. Since the metal ball 54 is made of a high-quality metal material, the metal ball 54 can overcome the upward resistance of the cement to the swinging members, so that the swinging members will fall back to the original position under the gravity of the metal ball 54. Based on this, as long as the dual-axis motor 51 works intermittently, the swinging members can continuously rotate, rise and then fall, thereby continuously carrying the cement below the feed bin 4 to the upper part, which can effectively prevent the cement from sedimenting at the bottom of the feed bin 4 and causing segregation.

[0043] Furthermore, the stirring mechanism 7 is composed of a mounting frame 71, a movable shaft 72, a turntable 73, a connecting member 74, a straight rod 75, a reciprocating rod 76, an L-shaped connecting rod 77, a vertical rod 78 and a stirring plate 79; the mounting frame 71 is Z-shaped and fixedly installed on one side of the upper surface of the material box 4 away from the screw conveyor mechanism 9, the movable shaft 72 is movably penetrated through the side wall of the mounting frame 71, one end of the movable shaft 72 close to the dual-axis motor 51 is connected with a driving source, and the other end is fixedly connected with the turntable 73. The straight rod 75 is movably connected to a non-central position on the side of the turntable 73 away from the movable shaft 72 through the connecting member 74. The reciprocating rod 76 is movably penetrated through the top wall of the mounting frame 71. The lower end of the reciprocating rod 76 is fixedly connected to one end of the straight rod 75 away from the connecting member 74, and the other end is fixedly connected to the L-shaped connecting rod 77; a horizontal plate is fixedly connected to the lower end of the L-shaped connecting rod 77. There are several vertical rods 78, all fixedly connected to the lower side of the horizontal plate. There are several stirring plates 79, which are respectively fixedly connected to the lower side of each vertical rod 78 and extend into the loading box 21.

[0044] In the present invention, the connecting member 74 is composed of a ball groove and a rolling ball. The ball groove is fixedly connected to the turntable 73, and the rolling ball is fixedly connected to the straight rod 75. The rolling ball is movably embedded in the ball groove, so that the adjustment of any angle between the straight rod 75 and the turntable 73 can be realized.

[0045] Specifically, under the action of the driving source, the movable shaft 72 will rotate, thereby driving the turntable 73 to rotate. Since the connection mode between the turntable 73 and the straight rod 75 is an activity connection with adjustable angles at any angle, and the connection with the reciprocating rod 76 is a fixed connection, on this basis, the straight rod 75 will drive the reciprocating rod 76 to perform a reciprocating up and down movement, and at the same time, the reciprocating rod 76 will also perform a rotational reciprocating movement of less than one full circle, so that the reciprocating rod 76 performs two kinds of movements simultaneously; the reciprocating rod 76 will drive the vertical rod 78 and the stirring plate 79 to move accordingly through the L-shaped connecting rod 77, so that the stirring plate 79 also has two simultaneous movement states of reciprocating up and down movement and rotational reciprocating movement; in the above movement state, the stirring plate 79 will continuously stir the cement at the bottom inside the loading box 21 upward, so as to effectively avoid the segregation of the base cement.

[0046] Furthermore, a transmission mechanism 6 associated with the stirring mechanism 7 and the screw conveyor mechanism 9 is provided above the dual-axis motor 51. The transmission mechanism 6 is composed of a first bevel gear 61, a second bevel gear 62 and a third bevel gear 63. The first bevel gear 61 is connected to the end of the rod shaft of the screw in the screw conveyor mechanism 9. The second bevel gear 62 is fixedly connected to the upper output end of the dual-axis motor 51. The third bevel gear 63 is fixedly connected to the end of the movable shaft 72 away from the turntable 73. Both the first bevel gear 61 and the third bevel gear 63 are meshed with the second bevel gear 62.

[0047] Specifically, when the biaxial motor 51 operates, it drives the second bevel gear 62 to rotate. The second bevel gear 62 drives the first bevel gear 61 and the third bevel gear 63 to rotate accordingly, causing the second bevel gear 62 to drive the screw rod in the screw conveyor mechanism 9 to rotate, and at the same time, the third bevel gear 63 drives the movable shaft 72 to rotate. The advantage of this setting is that through a single biaxial motor 51, the power source can be provided for the conversion mechanism 5, the screw conveyor mechanism 9, and the stirring mechanism 7 simultaneously. On the one hand, it can save equipment costs, and on the other hand, it can make the connection between various parts of the mechanism more compact, thus making the structure more stable.

[0048] Furthermore, the stirring mechanism 8 is composed of an electric cylinder 81, a connecting seat 82, a splined outer shaft 83, a propeller 84, a splined inner shaft 85, and a rotating motor 86. The rotating motor 86 is fixedly installed on the outer side wall of the loading box 21. The output shaft of the rotating motor 86 passes through the carriage 2 and extends into the loading box 21, and is fixedly connected to one end of the splined inner shaft 85. The propeller 84 is fixedly sleeved on the outer wall of the splined outer shaft 83. One end of the splined outer shaft 83 is movably sleeved on the splined inner shaft 85, and the other end is movably installed in the connecting seat 82. The electric cylinder 81 is fixedly installed on the outer side wall of the loading box 21 away from the rotating motor 86. The telescopic end of the electric cylinder 81 passes through the side wall of the loading box 21 and extends into the loading box 21 to be fixedly connected to the connecting seat 82.

[0049] Specifically, when the electric cylinder 81 and the rotating motor 86 are started simultaneously, the rotating motor 86 drives the splined inner shaft 85 to rotate. Since the connection between the splined inner shaft 85 and the splined outer shaft 83 is a key connection, the splined inner shaft 85 will drive the splined outer shaft 83 to rotate accordingly. The splined outer shaft 83 drives the propeller 84 to rotate. At the same time, the electric cylinder 81 drives the connecting seat 82 to move back and forth left and right. Since the connection between the connecting seat 82 and the splined outer shaft 83 is a movable connection, that is, the splined outer shaft 83 can rotate in the connecting seat 82, the connecting seat 82 can drive the splined outer shaft 83 to move back and forth left and right while the splined outer shaft 83 is rotating. The splined outer shaft 83 then drives the propeller 84 to move back and forth left and right. In summary, the propeller 84 can rotate and move back and forth left and right at the same time, thereby fully stirring the cement inside the loading box 21, making the stirring effect of the cement better, and greatly reducing the probability of cement segregation.

[0050] The working principle of the present invention:

[0051] When paving with the above paver, first inject a sufficient amount of cement into the loading box 21. Since the loading box 21 is connected to the transition box 23, under the action of gravity, the cement will flow along the inclined plate 22 into the transition box 23, filling the transition box 23 with cement. Subsequently, start the spiral conveyor mechanism 9, the conversion mechanism 5, the stirring mechanism 7, and the mixing mechanism 8. Then, the cement in the loading box 21 will flow into the transition box 23 after the action of the stirring mechanism 7 and the mixing mechanism 8, and then enter the material box 4 through the transmission of the spiral conveyor mechanism 9. When there is a certain amount of cement in the material box 4, the conversion mechanism 5 will act on the cement. The cement that has passed through the action of the conversion mechanism 5 will flow back into the loading box 21 through the pipeline to repeat the above process, realizing the cyclic action of the stirring mechanism 7, the mixing mechanism 8, and the conversion mechanism 5 on the cement, keeping the cement in a moving state at all times.

[0052] When performing the leveling operation of the cement, only need to open the solenoid valve 25 and keep the main body 1 of the machine running at a constant speed on the road surface. The cement that has undergone the cyclic action of the stirring mechanism 7, the mixing mechanism 8, and the conversion mechanism 5 will flow to the ground through the discharging nozzle 24 in the transition box 23 and be rolled flat by the subsequent flattening roller 3, thus completing the cement paving. At the same time, since the loading box 21 is connected to the transition box 23 and the lower end of the inclined plate 22 faces the connection port of the loading box 21 and the transition box 23, under the action of gravity, the cement inside the transition box 23 is always full. When a part of the cement flows out from the discharging nozzle 24, another part of the cement is still conveyed to the material box 4 by the spiral conveyor mechanism 9 to repeat the previous cyclic action process.

[0053] In short, whether it is in the paving operation period or not, the stirring mechanism 7, the mixing mechanism 8, and the conversion mechanism 5 can all act on the cement cyclically. The triple interference keeps the cement in a highly efficient moving state, so that the cohesion between the cement components is uniform, avoiding the phenomenon of coarse aggregate sinking and mortar floating, and then making the cement stable without the bad situation of base segregation, and the anti-segregation effect is excellent.
