Description

1. Description of the utility model.

1.1. The field of technology.

This utility model relates to machines for the construction and repair of roads, and is intended for the simultaneous distribution of binder (bitumen or bitumen emulsion) and crushed stone on the surface of the road surface with a rough surface treatment of the road surface.

1.2. The level of technology.

Known machines company SECMAIR, France, designed for the simultaneous distribution of binder and crushed stone on the surface of the roadway. These machines are described at http://www.secmair.fayat.com. SECMAIR machines contain a self-propelled chassis on which a binder container is mounted, a dumping body for crushed stone, a crushed stone distribution mechanism, and a binder dispensing device. The crushed stone distribution mechanism is located at the rear of the body. The receipt of crushed stone from the body to the mechanism of distribution of crushed stone occurs due to the lifting of the body during operation, by gravity.

A known unit for repair and restoration of road surfaces (RF patent No. 2149943), having a layout of the main elements similar to SECMAIR machines.

A drawback of the design of these machines is the lack of an overload mechanism for loading crushed stone into the car body from the bodies of dump trucks, as a result of which, when performing work, an additional unit of equipment (usually a front-end loader) has to be used, which increases the cost of the process of rough surface treatment and also leads to the risk of emergencies at the site of work, due to the fact that the front loader when loading crushed stone into the car body from the car body the dump truck has to travel outside the treated lane.

Known bituminous distributor DS-180 produced by OJSC "Kurgandormash", Russia. The DS-180 bitumen distributor is described on the website http://www.kzdm.ru. The DS-180 bitumen distributor has a tank for a binder, a body for crushed stone, a mechanism for distributing crushed stone, a device for pouring a binder. The crushed stone distribution mechanism of the DS-180 bitumen crusher is located in the middle part of the body. The receipt of crushed stone from the body to the mechanism of distribution of crushed stone occurs due to the natural shape of the body, by gravity. Additionally, the DS-180 bitumen distributor has a mechanism for loading crushed stone into the body in the form of a conveyor reloader with a receiving hopper located at the rear of the machine.

The design drawback of the DS-180 bituminous distributor is that the conveyor reloader has large dimensions and weight, which does not allow it to be compactly folded in the transport position, as a result of which the machine is structurally made in the form of a semi-trailer to the automobile tractor, in a state coupled to the tractor it has a large length low maneuverability and for this reason is inconvenient in work.

Known combined machine COMBIMAS 10 for in-line surface treatment, manufactured by MASSENZA. The description of the machine COMBIMAS 10 is given on the website http://www.massenza.ru. The COMBIMAS 10 machine has a self-propelled chassis, a binder container, a crushed stone body, a crushed stone distribution mechanism, a binder spreader, a crushed stone loading mechanism in the body in the form of a conveyor loader with a receiving hopper located at the rear of the machine, while this mechanism is connected to a self-propelled chassis lever system, and has the ability after loading the body with gravel to clean up the space above the body in the transport position, using hydraulic cylinders. The crushed stone distribution mechanism is located at the rear of the machine. According to the totality of features, the combined machine COMBIMAS 10 can be considered the closest of the existing analogues of the utility model (prototype).

The design drawback of the COMBIMAS 10 combined machine is that the shape and location of the crushed stone body do not allow crushed stone to independently enter the crushed stone distribution mechanism by gravity, there is no body lifting system, as a result of which two additional screw conveyors are used for crushed stone from the body to the crushed stone distribution mechanism feeding of crushed stone, which complicates and increases the cost of the design of the machine.

The task underlying this utility model is to create a machine for the synchronous distribution of bitumen and gravel with a design that is free from these drawbacks inherent in technical solutions representing the prior art.

This problem is solved due to the fact that the proposed machine contains a self-propelled chassis on which a binder container is located, a tipper body for crushed stone, a crushed stone distribution mechanism located in the rear of the crushed stone body, a binder spill device located in the rear of the machine, and there is also a mechanism for loading crushed stone into the body in the form of a conveyor reloader with a receiving hopper, while this mechanism is located behind the body, is connected to the body by levers, and can be removed after loading the body with crushed stone into the space above the body in the transport position, using hydraulic cylinders. The receipt of crushed stone from the body to the mechanism of distribution of crushed stone occurs due to the lifting of the body during operation, by gravity.

The technical result of the utility model is that:

- the machine allows you to perform work on the synchronous application of bitumen and gravel on the road surface without the use of additional overloading equipment for overloading gravel from dump trucks into the car body, due to the presence of its own overload device;

- the design of the machine is simple and lower cost of manufacture, compared with the known analogues, due to the lack of additional transporting devices between the body for gravel and the distribution mechanism of gravel;

- the design of the machine is compact and provides maneuverability, due to the fact that it is based on a self-propelled automobile chassis, and not on a semi-trailer.
