A vehicle-mounted road solid binder spreader

Abstract

A vehicular spreader of a solid road binder comprises a storage bin, a material conveying mechanism, a material distributing mechanism, a spreading mechanism and a dust removal device, wherein the storage bin is of a square sealed box structure, openable and closable charging holes are formed in the top of the storage bin, the material conveying mechanism is in seal connection with the low part of the storage bin, and is corresponding to a discharge hole in the lower part of rear end of the storage bin; the rear end of the storage bin is in seal connection with the dust removal device additionally; the lower end of the dust removal device is in seal connection with the material distributing mechanism, the position of the material distributing mechanism directly faces an output end of the material conveying mechanism, and the spreading mechanism is in seal connection with the lower end of the material distributing mechanism; the vehicular spreader has the characteristics of being reliable in performance, reasonable in structure, easy to operate and maintain, environment friendly in construction and the like.

Description

technical field [0001] The invention relates to a vehicle-mounted road solid binder spreader, which belongs to the technical field of road construction machinery. Background technique [0002] In the process of road base soil stabilization and road in-situ cold regeneration construction, it is necessary to spread solid binder in order to improve the base soil strength, improve its compaction performance, or improve the structural strength and mechanical properties of the original road materials after regeneration performance and improve its performance. Commonly used solid binder materials include lime, cement, fly ash or a mixture of the above materials prepared in a certain proportion. The construction methods in use generally include manual construction and mechanical spreading. The procedure of manual construction is to divide the pavement to be constructed into squares of equal area, and calculate the material quality required for each square according to the requirem...

Problems solved by technology

The procedure of manual construction is to divide the pavement to be constructed into squares of equal area, and calculate the material quality required for each square according to the requirements of the spreading amount per square (usually converted to the number of bags of standard specification bagged materials) ), put the bagged solid binder into the grid, and then spread it manually. This method is not only time-consuming and labor-intensive, but the spreading amount cannot be guaranteed, and the personnel are polluted by dust and their health is threatened; mechanical construction Generally, the suspended gravel spreader used in the chip sealing layer is installed on the back of the dump truck filled with solid binder to spread the material. Due to the original design of the suspended gravel spreader It is used for spreading crushed stones. Usually, the particle size and porosity of crushed stones are large, but this kind of fine-grained materials have fine particles and small porosity. The suspended gravel spreader is used for spreading solid binder materials. Inaccurate measurement and inaccurate control, and open construction has defects such as unable to effectively suppress dust and serious pollution
