DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present invention: a mobile concrete mixing device for water conservancy construction, including a mobile towing flatbed truck 1, a mixer guardrail 2, a concrete mixer 3, and a mixer limiting device 12. A protective limiting frame 8 is fixedly connected to the middle of the top end of the mobile towing flatbed truck 1. Hydraulic shock-absorbing rods 9 are uniformly and fixedly installed inside the protective limiting frame 8. A buffer spring 10 is nested outside the hydraulic shock-absorbing rods 9. A buffer support frame 7 is movably inserted into the outer top end of the protective limiting frame 8. The top end of the hydraulic shock-absorbing rod 9 is fixedly installed at the inner top end of the buffer support frame 7. The buffer support frame 7 and the protective limiting frame 8 can protect the internal hydraulic shock-absorbing rods 9 and buffer springs 10. Two fixing brackets 11 are symmetrically and fixedly connected to the top end of the buffer support frame 7. The concrete mixer 3 is movably connected to the top end of the buffer support frame 7.

[0022] The mixer limiting device 12 includes connecting brackets 15. There are multiple connecting brackets 15. Connecting shafts 13 are respectively rotatably connected to both ends of the connecting brackets 15. The length of the mixer limiting device 12 can be adjusted according to the size of the concrete mixer 3 to apply limiting fixation to the concrete mixer 3. Limiting rollers 14 are respectively rotatably connected to both ends of the connecting shaft 13.

[0023] The mixer guardrails 2 are symmetrically distributed at both ends of the protective limiting frame 8, and the bottom end of the mixer guardrails 2 is fixedly connected to the top end of the mobile towing flatbed truck 1. Two movable guardrails 4 are symmetrically and slidably inserted between the two mixer guardrails 2. The two movable guardrails 4 are distributed on both sides of the protective limiting frame 8. The concrete mixer 3 is safely protected by inserting the movable guardrails 4 into the mixer guardrails 2 to prevent it from tipping and falling when moving the concrete mixer 3.

[0024] Two slots 5 are symmetrically opened on one side of the mixer guardrail 2 close to the protective limiting frame 8. Two limiting insertion rods 6 are respectively fixedly connected to both ends of the movable guardrail 4. The limiting insertion rods 6 are slidably inserted into the inner side of the slots 5. When using the concrete mixer 3 for mixing, the two movable guardrails 4 are removed from the mixer guardrails 2 by an external force. When it is necessary to move the concrete mixer 3, the two movable guardrails 4 are inserted between the two mixer guardrails 2 by an external force to protect the concrete mixer 3.

[0025] Two connecting brackets 15 are connected by a connecting shaft 13, and the connecting brackets 15 located at both ends of the mixer limiting device 12 are rotatably connected to the top of the fixed bracket 11 through the connecting shaft 13. The limiting rollers 14 are rollingly connected to the outside of the concrete mixer 3. The mixer limiting device 12 covers the outside of the concrete mixer 3 and installs the connecting brackets 15 at both ends of the mixer limiting device 12 on the tops of the two fixed brackets 11 respectively through the connecting shaft 13, so as to fix the concrete mixer 3. At the same time, the rolling connection between the limiting rollers 14 and the outside of the concrete mixer 3 can avoid damaging the outer shell of the concrete mixer 3.

[0026] Working principle: During the use process, when it is necessary to move the concrete mixer 3, the mixer limiting device 12 is covered on the outside of the concrete mixer 3 by an external force, and the two ends of the mixer limiting device 12 are respectively connected to the tops of the two fixed brackets 11 through the connecting shaft 13. Then, the mobile towing trailer 1 is pulled by a tractor to move to the required position. During the movement, when the road surface is uneven, the moving mobile towing trailer 1 generates bumps. The bumps of the mobile towing trailer 1 drive the buffer support frame 7 to shake. The shaking buffer support frame 7 presses down on the hydraulic shock-absorbing rod 9 and the buffer spring 10. The buffer spring 10 buffers the pressure. At the same time, the hydraulic shock-absorbing rod 9 absorbs kinetic energy and converts it into heat energy, thereby eliminating vibration. At the same time, the concrete mixer 3 is fixed by the mixer limiting device 12, improving the stability between the concrete mixer 3 and the buffer support frame 7. During the movement, when the concrete mixer 3 generates shaking, the limiting rollers 14 in the mixer limiting device 12 roll on the outside of the concrete mixer 3, thereby reducing the damage to the concrete mixer 3. When using the concrete mixer 3 for mixing, the mixer limiting device 12 is removed by an external force. The shaking generated during the mixing operation of the concrete mixer 3 can be buffered by the hydraulic shock-absorbing rod 9 and the buffer spring 10, thereby reducing the damage to the wheels and axles in the mobile towing trailer 1.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
