[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4This utility model provides a technical solution: an asphalt concrete mixing arm device, including a mixing shaft 1, a first mounting base 11, and a second mounting base 12. A connecting component is provided between the first mounting base 11 and the second mounting base 12. Adjustable distance components are provided on one side of both the first mounting base 11 and the second mounting base 12. The connecting component includes a first recess 21 opened on one side of the first mounting base 11, a second recess 22 opened on one side of the second mounting base 12, a through opening 23 opened on one side of the first recess 21, a push rod 24 disposed in the through opening 23, a push plate 25 fixedly connected to one end of the push rod 24, an annular groove 26 opened on the inner wall of the through opening 23, an annular plate 27 fixedly connected to the outer side of the push rod 24, and a first spring 26 fixedly connected to one side of the annular plate 27. 8. A first inclined plate 29 fixedly connected to the other end of the push rod 24, a second inclined plate 30 cooperating with the first inclined plate 29, a movable plate 31 fixedly connected to one side of the second inclined plate 30, a locking rod 32 fixedly connected to the movable plate 31, a locking groove 33 formed in the inner wall of the second recess 22, a groove 34 formed in the inner wall of the first recess 21, a guide rod 35 fixedly connected to the second inclined plate 30, and a second spring 36 sleeved on the outside of the guide rod 35. The guide rod 35 is slidably connected to the groove 34, the annular plate 27 is slidably connected to the annular groove 26, and the push rod 24 is slidably connected to the through port 23. By pushing the push plate 25, the push rod 24 can be moved, and the push rod 24 can drive the first inclined plate 29 to move. At the same time, the first spring 28 deforms, and the first inclined plate 29 can squeeze the second inclined plate 20. The movement of the second inclined plate 30 causes the second spring 36 to deform, which in turn moves the locking rod 32. The first mounting base 11 and the second mounting base 12 can then fit against the outer side of the stirring shaft 1. The return of the first spring 28 and the second spring 36 causes the first inclined plate 29 and the second inclined plate 30 to return to their original positions, allowing the locking rod 32 to engage in the locking groove 33. This allows for quick and easy fixing of the first mounting base 11 and the second mounting base 12, improving installation efficiency. Limiting grooves 51 are provided on both sides of the second mounting base 12, and limiting blocks 52 are fixedly connected to both sides of the first mounting base 11. The limiting blocks 52 are inserted into the limiting grooves 51, facilitating alignment of the first mounting base 11 and the second mounting base 12. For connection and fixation, protective covers 61 are provided on both sides of the first mounting base 11. A knob 62 is fixedly connected to the outer side of each protective cover 61. The protective cover 61 is screwed to the first mounting base 11. The protective cover 61 protects the push plate 25 and push rod 24, preventing them from moving due to concrete collision. Multiple evenly arranged rolling grooves 81 are provided on one side of the second inclined plate 30. Ball bearings 82 are provided in the rolling grooves 81. The first inclined plate 29 can contact the ball bearings 82 and push them to roll within the rolling grooves 81, reducing friction between the first inclined plate 29 and the second inclined plate 30. Slots 91 are provided on both sides of the stirring shaft 1. Insert rods 92 are fixedly connected to the inner walls of the first mounting base 11 and the second mounting base 12, and the insert rods 92 are inserted into the slots 91.The insert rod 92 can be inserted into the slot 91, which can further improve the connection stability between the first mounting base 11 and the second mounting base 12 and the stirring shaft 1, and prevent vertical displacement.

[0026] Please see Figure 1 , Figure 2 , Figure 5 as well as Figure 6 The adjusting component includes a first arm plate 41 fixedly connected to one side of the first mounting base 11 and the second mounting base 12 respectively, an adjusting groove 42 formed on one side of the first arm plate 41, a second arm plate 43 disposed in the adjusting groove 42, a plurality of positioning grooves 44 evenly arranged on one side of the second arm plate 43, and a positioning screw 45 connected to the first arm plate 41. The positioning screw 45 is screwed to the first arm plate 41 and inserted into the positioning groove 44. The second arm plate 43 is slidably connected to the adjusting groove 42. By rotating the positioning screw 45, it can be disengaged from the positioning groove 44, thereby adjusting the distance. The second arm plate 43 is released and can then be pulled to move it to a suitable position. The positioning screw 45 is rotated in the opposite direction to lock it into another slot 33, which can fix the adjusted second arm plate 43 and prevent it from resetting. A guide groove 71 is provided on one side of the adjustment groove 42, and a guide block 72 is slidably connected in the guide groove 71. The guide block 72 is fixedly connected to the second arm plate 43, and the second arm plate 43 can drive the guide block 72 to move. The guide block 72 can prevent the second arm plate 43 from tilting and improve its adjustment stability.

[0027] Working principle: During operation, pushing the push plate 25 moves the push rod 24, which in turn moves the annular plate 27 and the first inclined plate 29. The movement of the annular plate 27 deforms the first spring 28. The movement of the first inclined plate 29 brings it into contact with the ball bearing 82, pushing the ball bearing 82 and the second inclined plate 30 to move. The movement of the second inclined plate 30 moves the moving plate 31 and the guide rod 35. The movement of the guide rod 35 deforms the second spring 36. The movement of the moving plate 31 moves the locking rod 32, which in turn moves the insertion rod 92 into the slot 91. At this point, the moving plate 31 and the locking rod 32 enter the second recess 22, aligning the locking rod 32 with the slot 33. Releasing the push plate 25 resets the first spring 28 and the second spring 36. This allows the first inclined plate 29 and the second inclined plate 30 to be reset, thereby allowing the locking rod 32 to be engaged in the locking groove 33. This fixes the first mounting base 11 and the second mounting base 12. Then, the protective cover 61 is screwed onto the first mounting base 11. When it is necessary to adjust the position of the second arm plate 43, the positioning screw 45 can be turned to move it away from the positioning groove 44. At this time, the second arm plate 43 can be pulled to move it. After adjusting the second arm plate 43 to the appropriate position, the positioning screw 45 is turned in the opposite direction to insert it into the positioning groove 44, which can fix the adjusted second arm plate 43. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
