Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a handcart for automatically dispensing mortar or concrete used in construction engineering. Background Technology

[0002] In construction engineering, whether it is pouring concrete structures, building walls, or plastering walls, a large amount of mortar or concrete materials are required. Usually, ready-made mortar or concrete is transported to the construction site by large-tonnage professional transport vehicles. At the construction site, this ready-made mortar or concrete is loaded into wheelbarrows for secondary handling. Then, the ready-made mortar or concrete is shoveled from the wheelbarrows into small buckets by workers to be transported to professional workers. This kind of process involves repetitive physical labor, is time-consuming, and reduces work efficiency. Therefore, there is an urgent need to improve the process or construction equipment to reduce labor intensity, improve work efficiency, and increase overall economic benefits.

[0003] Chinese patent document with announcement number CN2214110879 U (patent number CN202023121229.0, publication date September 3, 2021) discloses a mortar or concrete storage tank with multiple discharge ports, including a main body, a mixing zone inside the main body, a rotating ring movably installed at the bottom of the main body, a connecting zone on the bottom surface of the rotating ring, a first leakage hole on the top of the rotating ring, and a rotating zone on the inner side of the rotating ring. This type of mortar or concrete storage tank has the following three shortcomings: 1. The mortar or concrete storage tank lacks a moving device, making it impossible to transport directly to the construction site. Additional material transport tools are required, which greatly limits the functionality of this device; 2. This type of mortar or concrete storage tank with multiple discharge ports is cumbersome to manufacture, inconvenient to operate, and difficult to clean after use, failing to meet the requirements of civilized construction and environmental protection; 3. Using this device makes it impossible to dispense mortar or concrete materials into small buckets for convenient distribution to individual workers, still requiring manual dispensing, significantly reducing work efficiency.

[0004] Therefore, there is an urgent need for a handcart that can work normally on the construction site and automatically dispense mortar or concrete. Utility Model Content

[0035] In actual use, construction workers place the stacked handcarts below the discharge port of the large mortar or concrete transport vehicle. They then move the pin in the latch on cart one upwards, engaging the lever in the middle with the L-shaped support rod, thus separating cart one and cart two. Cart one and cart two are then pulled apart to their maximum distance. Each group of six buckets, with their openings facing upwards, is placed in cart two. A partition is placed on the opening of each of the six buckets. The discharge port switch of the mortar or concrete transport vehicle is then opened, and the mortar or concrete is poured into the six buckets in cart two one by one. Excess material is wiped off the top of the six buckets. Cart one is then moved from cart one to directly above cart two. The pin in the latch on cart one is moved downwards and inserted into the locking lug at the top of the front plate 211 of cart two. At this point, cart one and cart two are combined into a single unit. Similarly, place each set of six buckets, opening upwards, in the first bucket of cart one. Place a partition over the opening of each bucket. Then, open the discharge port of the finished mortar or concrete transport vehicle and pour the finished mortar or concrete into the six buckets in the first bucket, wiping away any excess material from the top of the buckets. Operate the second handle of cart two to move the cart to the work site of the professional worker, remove the partition in cart one or cart two, and lift out the buckets from cart one or cart two for use. This eliminates the repetitive manual labor of shoveling the finished mortar or concrete into small buckets one by one from the cart and then transporting them to the professional worker.
