Description

Technical Field

[0001] This utility model relates to the field of concrete mixer truck technology, and in particular to a mixer truck anti-spillage device. Background Technology

[0002] A concrete mixer truck is a specialized truck used to transport concrete for construction; it is also often called a "snail truck." These trucks are equipped with a cylindrical mixing drum to carry the mixed concrete. During transport, the mixing drum continues to rotate to ensure the concrete does not harden. After delivery, the inside of the mixing drum is usually rinsed with clean water to prevent residual concrete from hardening and taking up space.

[0003] Chinese Patent Publication No. (CN220198101U) discloses a spill-proof receiving hopper for a concrete mixer truck, including a receiving hopper assembly. The receiving hopper assembly includes a receiving hopper body, with mounting plates welded and fixed to the front and rear sides of the right outer wall of the receiving hopper body. The ultra-high molecular weight polyethylene liner has strong anti-stick properties, making it difficult for concrete to stick to the liner. When the concrete solidifies, it can be easily cleaned with a scraper, ensuring the overall receiving quality. After receiving the concrete, the spring rod is pulled outward, and the receiving hopper is rotated to the right by holding the handle to pour out the concrete for easy cleaning. During installation, the fixing post is snapped into the U-shaped bracket, and the spring rod is inserted into the fixing post to fix the receiving hopper part, allowing for receiving operations. When it is necessary to unload the concrete, the spring rod is pulled outward, and the receiving hopper is rotated to the right to the side below the mounting platform to unload, ensuring the overall performance.

[0004] However, the above-mentioned utility model still has the following problems: When unloading the concrete in the receiving hopper, the above-mentioned utility model requires the staff to hold the handle and drive the receiving hopper to rotate in order to complete the unloading work. However, in actual use, due to the large weight of the concrete, once the concrete content in the receiving hopper is large, it will be more difficult to manually pull the receiving hopper or even it will be impossible to pull it, thus affecting the unloading efficiency. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a material spillage prevention device for a mixer truck, which has the effect of automatic unloading.

[0016] A further feature of this invention is that a discharge pipe is fixedly connected to the bottom of one side of the receiving hopper, and a valve is provided on the outer surface of the discharge pipe.

[0017] By adopting the above technical solution, and by setting up a discharge pipe and valve, when the amount of concrete in the receiving hopper is small, the discharge pipe can be opened through the valve to discharge the concrete from the receiving hopper.

[0018] A further feature of this invention is that a stabilizing plate is fixedly connected to the top of the tilting table, an arc-shaped groove is formed on the outer surface of the stabilizing plate, and a slider is fixedly connected to the outer surface of the receiving hopper, the slider being slidably connected to the arc-shaped groove.

This design achieves the effect of automatic tilting of the hopper, that is, it realizes... The automatic unloading function of the concrete inside the receiving hopper avoids the trouble of manually turning the receiving hopper, saves manpower, enhances the degree of automation, and improves the unloading efficiency of the device. By setting up a buffer box, shock-absorbing springs, limit plates, connecting plates, and rectangular slots, when the drive cylinder drives the receiving hopper to reset, the moment the buffer plate contacts the turning table, the shock-absorbing springs inside the buffer box are compressed through the connecting plate and limit plate, which plays a role in buffering and protecting the receiving hopper. After the receiving hopper is fully reset, the buffer plate is just locked into the rectangular slot on the turning table, realizing the fixing function of the receiving hopper and effectively improving the stability of the receiving hopper in a static state.
