[0020] Reference Figure 1 The figure shows a preferred embodiment of the present invention.

[0021] The mixing equipment 10 for cold patch asphalt mixture includes a mixing pot 20, the mixing pot 20 has a cavity arranged with an upward opening, a first fixing member and a second fixing member are provided on the side wall of the mixing pot 20, the first fixing member and the second fixing member, and the line between the first fixing member and the second fixing member passes through the center of the mixing pot 20, a first cable 30 is connected to the first fixing member, and the other end of the first cable 30 is fixedly connected to the first driving device; the first driving device includes a first motor, a first eccentric wheel 40 is provided on the rotating shaft of the first motor, and the end of the first cable 30 is fixedly arranged on the first eccentric wheel On the heart wheel 40; a second cable 31 is connected to the second fixing member, and the other end of the second cable 31 is fixedly connected to the second driving device; the second driving device includes a second motor, and a second eccentric wheel 41 is provided on the rotating shaft of the second motor, and the end of the second cable 31 is fixedly arranged on the second eccentric wheel 41; when the first eccentric wheel 40 and the second eccentric wheel 41 rotate, the mixing pot 20 swings back and forth up and down; the first motor drives the first eccentric wheel 40 to rotate, and the second motor drives the second eccentric wheel 41 to rotate, and the first eccentric wheel 40 and the second eccentric wheel 41 drive the mixing pot 20 to swing back and forth.

[0022] In the mixing equipment 10 for cold patch asphalt mixture provided above, during the process of stirring the cold patch asphalt mixture, the first motor drives the first eccentric wheel 40 to rotate, and the second motor drives the second eccentric wheel 41 to rotate. The first eccentric wheel 40 and the second eccentric wheel 41 drive the mixing pot 20 to swing back and forth. At this time, the mixing pot 20 swings in both horizontal and vertical directions. Compared with traditional agitators, during the swinging process of the mixing pot 20, all the cold patch asphalt mixture in the mixing pot 20 can be mixed without any dead angles in the mixing. Therefore, the cold patch asphalt mixture can be stirred more evenly, achieving a better stirring effect.

[0023] Specifically, the movement frequency of the first drive device and the second drive device are consistent, and the movement direction of the first drive device and the second drive device are consistent, that is, the two drive devices swing back and forth to the right or to the left at the same time, and the old road planing and milling materials are constantly shaken in the engine oil and diesel, thereby automatically mixing the cold patch asphalt mixture in the mixing pot 20.

[0024] In this way, when the first driving device and the second driving device are in operation, the first cable 30 and the second cable 31 located on both sides of the mixing pot 20 respectively drive the mixing pot 20 to swing back and forth, thereby facilitating the coordination between the old road planing and milling materials and the engine oil and diesel in the mixing pot 20. On the other hand, it can also realize automatic mixing of the old road planing and milling materials, engine oil and diesel without manual stirring, thus freeing up manpower.

[0025] The first eccentric wheel 40 and the second eccentric wheel 41 are arranged vertically. During the rotation of the first eccentric wheel 40 and the second eccentric wheel 41, due to the eccentric effect of the eccentric wheel, the first eccentric wheel 40 and the second eccentric wheel 41 can adjust the mixing pot 20 in height and length. Specifically, X and Z spatial rectangular coordinate systems are defined respectively. By rotating the first eccentric wheel 40 and the second eccentric wheel 41, the mixing pot 20 can be adjusted in the X-axis direction and the Y-axis direction.

[0026] In order to prevent the first eccentric wheel 40 and the second eccentric wheel 41 from interfering with each other during rotation, the rotation directions of the first eccentric wheel 40 and the second eccentric wheel 41 are defined to be consistent, and the rotation frequencies and rotation angles of the two are consistent.

[0027] Furthermore, in order to adjust the movement of the mixing pot 20 in the Y-axis direction, a first moving block 50 is arranged below the first motor. The first motor and the first moving block 50 are fixedly arranged, and the first moving block 50 reciprocates left and right on one side of the mixing pot 20. A second moving block 51 is arranged below the second motor. The second motor and the second moving block 51 are fixedly arranged, and the second moving block 51 reciprocates left and right on the other side of the mixing pot 20.

[0028] In the first embodiment, the first moving block 50 and the second moving block 51 move in opposite directions.

[0029] Through the cooperation between the first eccentric wheel 40, the second eccentric wheel 41, the first movable block 50 and the second movable block 51, the mixing pot 20 can be swung in the three directions of the X, Y and Z axes, so that the cold patch asphalt mixture is mixed more comprehensively and multi-directionally, thereby improving the mixing effect of the cold patch asphalt mixture in the mixing pot 20.

[0030] In the second embodiment, the first moving block 50 and the second moving block 51 move in opposite directions.

[0031] In addition, a stirring device is provided above the mixing pot 20. The stirring device includes a support rod 60 and a stirring claw. The stirring claw is placed at the end of the support rod 60 and extends into the interior of the mixing pot 20. The stirring claw is used to stir the asphalt mixture in the mixing pot 20. During the mixing of the cold-patch asphalt mixture, the stirring claw is placed inside the mixing pot 20 under the multi-directional shaking of the mixing pot 20 itself. The stirring claw does not need to be stirred and is in motion relative to the cold-patch asphalt mixture in the mixing pot 20, thereby achieving stirring of the cold-patch asphalt mixture in the mixing pot 20.

[0032] The stirring device can move along with the first moving block 50 , so that the stirring device will not be separated from the stirring pot 20 when the stirring pot 20 is shaken.

[0033] Of course, the stirring claws can also be capable of independently grasping and stirring the cold patch asphalt mixture. In this way, in conjunction with the shaking of the mixing pot 20, a better mixing effect of the cold patch asphalt mixture can be achieved.

[0034] The stirring claw includes a plurality of dispersedly arranged grippers 61. A plurality of stirring rods are provided on the side walls of the grippers 61. The plurality of stirring rods are spaced apart and arranged vacantly in different directions to expand the contact area with the cold patch asphalt mixture and further enhance the stirring effect of the cold patch asphalt mixture.

[0035] During the stirring process, the support rod 60 can rotate, and the support rod 60 drives the stirring claw located at the end to rotate, thereby improving the stirring efficiency.

[0036] A limiting device is provided at the bottom of the mixing pot 20. The limiting device is a universal wheel 71. A movable sleeve 70 is provided on the outer periphery of the universal wheel 71. The movable sleeve 70 rotates in all directions around the universal wheel 71. The upper end of the movable sleeve 70 is fixedly connected to the bottom of the mixing pot 20. In this way, when the mixing pot 20 swings in any direction of the X and Y axes, the limiting device does not affect its swinging, but can play a role in limiting the position of the mixing pot 20. The mixing pot 20 does not leave the limiting device, thereby avoiding the problem of spilling material and uncontrolled shaking of the mixing pot 20 during the swinging process.

[0037] A spring column 72 is also provided at the bottom of the limiting device. When the mixing pot 20 moves along the Z-axis driven by the first eccentric wheel 40 and the second eccentric wheel 41, the spring column 72 can be extended and retracted without affecting the shaking of the mixing pot 20 in the Z-axis direction. When the mixing pot 20 stops shaking, the spring column 72 restores its shape and continues to play the role of supporting and fixing the mixing pot 20. Moreover, while improving the stability of the mixing pot 20, it does not interfere with the shaking of the mixing pot 20 in the X, Y, and Z directions.

[0038] Another advantage of providing the spring column 72 is that when the mixing pot 20 moves along the Y-axis direction under the traction of the first movable block 50 and the second movable block 51, the spring column 72 is stretched and will not affect the movement of the mixing pot 20. When the mixing is completed, the first movable block 50 and the second movable block 51 stop operating, and the spring column 72 returns to the vertical arrangement state, and the mixing pot 20 is directly above the spring column 72. The spring column 72 supports the mixing pot 20, and is in a relatively stable state at this time.

[0039] The support rod 60 is rotatable.

[0040] The support rod 60 is retractable, and the distance between the stirring claw and the bottom of the mixing pot 20 can be adjusted by retracting it. When the amount of cold patch asphalt mixture in the mixing pot 20 is large, the support rod 60 can be retracted upward to stir the middle area of ​​the cold patch asphalt mixture. When the amount of cold patch asphalt mixture in the mixing pot 20 is small, the support rod 60 can be extended toward the bottom of the mixing pot 20 until it contacts the cold patch asphalt mixture.

[0041] The gripper 61 is provided with a heating device, which is arranged inside the gripper 61 and is used to heat the asphalt mixture during the mixing process.

[0042] The gripping handle 61 is arranged in a cylindrical pile shape, and an enlarged end is formed at the end of the gripping handle 61. The contact area between the enlarged end and the cold patch asphalt mixture is larger, which is convenient for stirring and heating the cold patch asphalt mixture.

[0043] In order to prevent interference between the heating device and the pot body of the mixing pot 20 during the shaking of the mixing pot 20 , the heating device is arranged inside the gripper 61 .

[0044] The heating device is arranged inside the gripper 61. Compared with arranging the heating device in other parts, the advantage is that during the mixing process, there is a larger contact area between the gripper 61 and the cold patch asphalt mixture, which facilitates the rapid transfer of heat to the cold patch asphalt mixture, has higher thermal conductivity, and conducts heat more evenly, so that all parts can be evenly heated, further improving the mixing quality and mixing efficiency of the cold patch asphalt mixture.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
