Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, specifically to a mobile concrete mixer. Background Technology

[0002] Commonly used mobile concrete mixers are shown in the attached image. Figure 1 As shown, it includes a support frame 1, a swing frame 6, a wheel frame 2, rollers 5, a mixing tank 7, an operating panel 9, a transmission mechanism, a drive device, and an angle adjustment and fixing mechanism 13. The wheel frame 2 is installed at the bottom of the support frame 1, and two rollers 5 are mounted on the wheel frame 2. The drive device includes a motor and a motor cover 10. The motor cover 10 and the operating panel 9 are respectively installed on both sides of the top of the support frame 1. The motor is installed inside the motor cover 10. The transmission mechanism includes a gear 17 and a gear ring 8. The gear 17 is fixedly installed on the transmission at the motor output end. On shaft 16, a drive shaft is installed on one side of the top of support frame 1. The operating plate 9 is fixedly connected to the drive shaft. The swing frame 6 is U-shaped. The two ends of the swing frame 6 are respectively connected to the drive shaft and the transmission shaft 16. The bottom of the mixing tank 7 is rotatably mounted on the swing frame 6. The inner wall of the mixing tank 7 is provided with a stirring blade assembly. The gear ring 8 is coaxially mounted on the mixing tank 7. The gear ring 8 meshes with the gear 17. The angle adjustment and fixing mechanism 13 is installed on the support frame 1 on one side of the operating plate 9. The angle adjustment and fixing mechanism 13 is used to lock or release the operating plate 9.

[0003] When using this type of mobile concrete mixer, the material is first poured into the mixing tank 7. Then, the operating disc 9 is released using the angle adjustment and fixing mechanism 13, and the worker manually rotates the operating disc 9. The operating disc 9 drives the drive shaft to rotate, which in turn drives the swing frame 6 to rotate. As the swing frame 6 rotates, the tilt angle of the mixing tank 7 changes accordingly. When the tilt angle of the mixing tank 7 reaches a suitable range, the operating disc 9 is locked using the angle adjustment and fixing mechanism 13, and the swing frame 6 remains stable. Finally, the motor is started, and the motor drives the gear 17 to rotate. The rotation of the gear 17 drives the gear ring 8 to rotate, thereby driving the mixing tank 7 to rotate around its own axis. The mixing blade assembly inside the mixing tank 7 mixes the material inside the mixing tank 7.

[0004] like Figure 2 As shown, the current wheel frame 2 includes an axle 3, with a baffle 301 fixedly installed on the outer circumferential surface of each end of the axle 3. When installing the roller 5, the roller 5 is first fitted onto the end of the axle 3 until the roller 5 is in contact with the baffle 301. Then, the retaining wire 12 is inserted into the locking hole at the end of the axle 3, thereby limiting the roller 5 to be located between the retaining wire 12 and the baffle 301.

[0005] The aforementioned commonly used mobile concrete mixers use retaining wire 12 and limiting roller 5, which are relatively troublesome to install, and the retaining wire 12 is also easy to detach. Utility Model Content

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 3-9 As shown, one embodiment of this utility model provides a mobile concrete mixer, including a support frame, which includes a support frame 1 and at least one wheel frame 2 connected to each other. A wheel axle 3 is fixedly installed on the wheel frame 2, and at least two rollers 5 are installed on each wheel axle 3. A baffle 301 is fixedly installed at each end of the wheel axle 3, and the two rollers 5 are rotatably installed at the two ends of the wheel axle 3, and the rollers 5 are in contact with the baffle 301. A snap cap 14 for fixing the rollers 5 is detachably installed at each end of the wheel axle 3. The snap cap 14 cooperates with the baffle 301 to restrict the movement of the rollers 5 along the axial direction of the wheel axle 3. On the circumferential surfaces of both ends of the axle 3, there are annular grooves 302 that correspond one-to-one with the baffles 301. The annular grooves 302 are located on the outer side of the corresponding baffles 301. A spring piece 141 is provided on one side of the snap cap 14. The snap cap 14 has a cavity inside. The spring piece 141 has a socket 142 that communicates with the cavity. The diameter of the socket 142 is smaller than the diameter of the axle 3 and larger than the inner diameter of the annular groove 302.

[0020] In this embodiment, when installing the roller 5, simply put the roller 5 onto the axle 3, then align the insertion hole 142 on the snap cap 14 with the axle 3 and press the snap cap 14 so that the end of the axle 3 is inserted into the insertion hole 142 on the snap cap 14. Since the diameter of the insertion hole 142 is smaller than the diameter of the axle 3 and larger than the inner diameter of the annular groove 302, after the spring piece 141 deforms, the spring piece 141 will be stuck into the annular groove 302 at the end of the axle 3. Since the spring piece 141 is stuck by the annular groove 302 at the end of the axle 3, and at the same time, the two sides of the roller 5 are in contact with the spring piece 141 and the baffle 301 respectively, the roller 5 is limited by the snap cap 14 and the baffle 301 and cannot move along the axial direction of the axle 3.

[0021] It is evident that using this clip cap 14 and the retaining roller 5 has at least the following advantages compared to using the retaining wire 12 and the retaining roller 5: First, the installation process is simpler and more convenient. Second, the clip cap 14 is less likely to fall off the axle 3, resulting in greater stability and a more secure fit. Third, it is more aesthetically pleasing.

[0022] In some embodiments, the snap cap 14 is any one of a hemispherical, cylindrical, or frustum-shaped form. As a specific embodiment, such as... Figure 6 and Figure 8 As shown, the buckle cap 14 is hemispherical.

[0023] In some embodiments, the snap cap 14 and the spring piece 141 are made of metal and integrally formed, preferably of alloy material.

[0024] It should be noted that the alloy spring 141 has a slight deformation capability. When the axle 3 presses the end face of the spring 141, the spring 141 is recessed towards the internal cavity of the snap cap 14 until the end of the axle 3 passes through the insertion hole 142 of the spring 141 and the spring 141 is inserted into the annular groove 302 at the end of the axle 3. When the spring 141 is inserted into the annular groove 302 at the end of the axle 3, the spring 141 returns to its natural state. After the spring 141 returns to its natural state, it cannot detach from the axle 3 because it is stuck in the annular groove 302 at the end of the axle 3, and therefore the snap cap 14 is also difficult to detach.

[0025] In this embodiment, as Figure 9 As shown, multiple U-shaped notches 143 are evenly distributed around the axis of the spring piece 141, and the notches 143 are connected to the insertion holes 142. The multiple U-shaped notches 143 divide the inner side of the spring piece 141 into several parts, so that the spring piece 141 can be more easily deformed when the wheel axle 3 presses the spring piece 141, which makes the installation work more convenient.

[0026] It should be noted that, as Figure 1As shown, the motor cover 10 of a traditional mobile concrete mixer has an opening on one side, through which a door panel 11 is fixedly installed using screws. Specifically, a round hole is made at each of the four corners of the door panel 11, and a screw hole is made at each of the four corners of the opening in the motor cover 10. When installing the door panel 11, it is fitted against the opening in the motor cover 10, and its position is adjusted so that the four round holes on the door panel 11 align with the four screw holes on the motor cover 10. Finally, the four screws are tightened in sequence.

[0027] Since the door panel 11 needs to be opened frequently to maintain the motor and controller components inside the motor cover 10, it is currently necessary to unscrew four screws to remove the door panel 11 in order to expose the opening of the motor cover 10. When installing the door panel 11 later, four screws need to be screwed in again, which makes the installation and disassembly process of the door panel 11 cumbersome.

[0028] To solve this technical problem, in this embodiment, as follows: Figure 4 and Figure 5 As shown, in this embodiment, a mounting hole 111 is provided at each of the four corners of the door panel 11. Each mounting hole 111 includes a connected circular hole and a U-shaped hole. That is, Figure 1 The door panel 11 of a traditional mobile concrete mixer has a round hole, while the mounting hole 111 in this application includes a connected round hole and a U-shaped hole. A screw hole corresponding to the mounting hole 111 is provided at each of the four corners of the opening on the motor cover 10.

[0029] Thus, when installing the door panel 11, the door panel 11 is fitted against the opening of the motor cover 10, and the position of the door panel 11 is adjusted so that the U-shaped holes of the four mounting holes 111 on the door panel 11 are aligned with the four screw holes on the motor cover 10. Then, the four locking screws 15 are tightened in sequence to fix the door panel 11 in place, thereby achieving the desired result. Figure 4 The state shown.

[0030] When removing the door panel 11, simply loosen the four locking screws 15. Under gravity, the screws 15 will then enter the round holes of the mounting holes 111. Since the diameter of these holes is larger than the diameter of the screw heads, the door panel 11 can be pulled out directly. This allows the door panel 11 to be removed smoothly without removing the four locking screws 15. When reinstalling the door panel 11, simply align the round holes of the four mounting holes 111 with the four locking screws 15, then push the door panel 11 so that all four locking screws 15 pass through the round holes simultaneously. Then push the door panel 11 upwards so that all four locking screws 15 simultaneously enter the U-shaped holes of the four mounting holes 111. Finally, tighten the four locking screws 15 in sequence. This greatly simplifies the removal and reinstallation of the door panel 11, saving time and effort.

[0031] In this embodiment, the mobile concrete mixer also includes a mixing tank 7, a swing frame 6, an operating disc 9, a gear ring 8, and an angle adjustment and fixing mechanism 13. The aforementioned support frame includes a connected support frame 1, wheel frames 2, and support legs 4, wherein the wheel frames 2 and support legs 4 are installed on both sides of the bottom of the support frame 1. The motor cover 10 is fixedly installed on the left side of the support frame 1 and near the top of the support frame 1. A drive shaft is installed on the top right side of the support frame 1, and the operating panel 9 is fixedly connected to the drive shaft. Furthermore, a motor is installed inside the motor cover 10, and a transmission shaft 16 and a gear 17 are sequentially installed at the motor's output end. The swing frame 6 is a U-shaped frame, with both ends fixed to the transmission shaft 16 and the drive shaft, respectively. The bottom of the mixing tank 7 is rotatably mounted on the swing frame 6 via a rotating shaft assembly, and a gear ring 8 is coaxially mounted on the mixing tank 7, with the gear 17 meshing with the gear ring 8.

[0032] Furthermore, the angle adjustment and fixing mechanism 13 is installed on the right side of the support frame 1, and the angle adjustment and fixing mechanism 13 is used to lock or release the operating panel 9.

[0033] It should be noted that the angle adjustment and fixing mechanism 13 is existing technology. It typically includes a brake disc mounted on the drive shaft and a clamping mechanism mounted on the support frame 1. The edge of the brake disc has multiple slots. The clamping mechanism is inserted into the slots of the brake disc to fix the brake disc and prevent the operating disc 9 from rotating, thereby keeping the mixing tank 7 in an inclined state.

[0034] In this embodiment, a trailer connector is installed on the support leg 4. The trailer connector is used to connect to a trailer, so that the trailer can be connected to the trailer to move the mobile concrete mixer.

[0035] In some embodiments, the support frame includes a support frame 1 and two wheel frames 2 connected to each other. The two wheel frames 2 are respectively installed on both sides of the bottom of the support frame 1, and each wheel frame 2 is equipped with two rollers 5. In this way, the mobile concrete mixer can be moved freely without the need for a trailer.
