Description

Wet mix mortar production vehicle

technical field

The utility model relates to the technical field of mixing, in particular to a wet mixing mortar production vehicle.

Background technique

Mortar refers to the mixture formed by mixing a certain proportion of cement, sand, water and other materials, which can be used for masonry, plastering and other construction operations. With the rapid advancement of urbanization, in order to take into account the increasing demand for mortar construction and the requirements of quality and environmental protection, many cities are currently promoting the use of ready-mixed mortar while gradually prohibiting on-site mixing of mortar.

Ready-mixed mortar mainly includes dry-mixed mortar and wet-mixed mortar. Among them, dry-mixed mortar refers to a powdery or granular mixture produced by a professional production plant by mixing dry and screened sand with cement, mineral admixtures and admixtures in a certain proportion. After the ordinary truck is transported to the construction site, it can be used after adding water and stirring according to the instructions. Wet-mixed mortar refers to a mortar mixture formed by mixing cement, sand, water-retaining thickening material, water, fly ash or other mineral admixtures and admixtures in a certain proportion; in a common way Among them, wet-mixed mortar is mostly produced by ordinary mixing plants, and after being transported to the construction site by mixer trucks, it is used up within the specified time.

When producing dry-mixed mortar, it is necessary to dry the wet sand, which has high energy consumption and cost. Therefore, in recent years, the industry has paid more attention to the development of wet-mixed mortar. In the traditional scheme, the mixing station used to produce wet-mixed mortar is generally an independent building, and it is located in a place with no residents or few residents (such as the urban-rural junction) to reduce the damage caused by pollution; for urban areas For construction projects, the mortar mixing station is usually quite a distance away from the construction site (such as 10 kilometers to 50 kilometers). Too long transportation distance and too long storage time will seriously affect the performance and spraying effect of mortar.

Based on this, relevant manufacturers in the industry have proposed various solutions on the basis of referring to the original concrete equipment. For example, the applicant proposed an original wet-mixed mortar production process route, and formed a corresponding complete set of mortar equipment (referred to as Mortar Master). Specifically, the complete set of mortar equipment can include sand hoppers, sand conveying equipment, mixing buildings, powder conveying equipment, powder tanks, sand screening machines, sand trucks, mixer trucks, and mortar pumps; among them, the mixing building, sand Hoppers, sand conveying equipment, powder tanks and powder conveying equipment are arranged near the construction site. The mixing building adopts a modular design without foundation to facilitate rapid movement and placement. The sand screening machine screens sand in the sand field and transports The sand truck transports the sand screened by the sand sieving machine to the sand hopper near the construction site, and the sand conveying equipment transports the predetermined amount of sand in the sand hopper to the mixing building, and the powder conveying equipment will store it in the powder tank (There can be more than one) The predetermined amount of cement or fly ash is transported to the mixing building, and other components such as water, admixtures, etc. are also transported to the mixing building according to the predetermined amount, and finally the mortar formed by mixing can be passed through the mixer truck Wait to transport to the construction site, and complete the pumping of the mortar by the mortar pump, and then complete the spraying of the mortar.

After adopting the aforementioned scheme, the defects and deficiencies in the traditional scheme can be effectively solved, and the performance and spraying effect of the mortar can be improved. However, this scheme also brings some new problems: for example, the number of equipment required for the entire mortar complete set of equipment Many, because a lot of equipment needs to be temporarily arranged near the construction site, which is not only limited by the site conditions, but also takes time and effort to arrange and install; in addition, the production capacity of this complete set of mortar equipment is relatively large, which can usually meet the mortar demand of multiple buildings , but for occasions where the demand for mortar is small (for example, when only one building’s mortar demand is required), the production capacity of this complete set of mortar equipment needs to be greatly reduced, resulting in low equipment use efficiency and high unit cost of mortar; in addition, In this scheme, it takes a certain amount of time from the production of the mortar to the use of the mortar. During this time, the performance and spraying effect of the mortar will also be affected.

In addition, in the field of mixing technology, the metering system is used to measure the weight of each material. Whether the metering system is accurate or not directly affects the quality and properties of the stirred mixture. In the prior art, the metering system is usually arranged above the main mixer. After each metering hopper measures each material, the material is then unloaded into the main mixer. However, during the working process, the mixing main engine often needs long-term high-frequency vibration, and considering other harsh working conditions around the mixing main engine, it is easy to cause the metering system to suffer from large and more vibrations and shocks. For systems that need to be transported and moved (such as the aforementioned complete set of mortar equipment), the vibration and impact suffered by the metering system will be more frequent and greater, so the metering system is prone to sensor damage or data distortion. In order to alleviate this phenomenon, it is often used in the metering system. Configure more sensors in the sensor or check and replace sensors frequently, but this method is time-consuming and laborious, and in many cases, the method of using more sensors is not feasible.

Therefore, how to solve the above problems and promote the further development of wet-mixed mortar and metering methods is the direction that the inventors of this application have been working hard and exploring.

1. As shown in FIG. 1 , a vibration damping pad 75 can be provided between the bracket 70 and the installation surface in the rear area of the cargo box 3 , so as to further avoid the impact of vehicle body vibration on the metering system 7 .

The semi-trailer chassis can be transported by being equipped with a corresponding tractor.

6.
