In the lower part of the body (1), the opening is covered by flaps (4) slidably mounted on the body itself (1), slidable by hydraulic motors (6). This whole structure is mounted on a chassis with one or more axles (5).

Description

Technical field

The technical solution concerns a trailer intended for the spreading of construction base materials, such as soil, gravel, etc., for the purpose of strengthening the subsoil. The technical solution falls into the field of construction, agronomic and wood industry.

Prior art

Trucks with tipping mechanisms, various trailers, etc. are widely used for the transport and dumping of construction base materials. As these are not primarily devices intended for even spreading of building materials, there is an irregular layering of base materials. This requires the subsequent use of other heavy equipment, such as crawler dozers, graders, loaders and the like.

When using these vehicles, there is not only uneven but also poorly controllable discharge of base materials. Their design does not allow the operator to correctly ensure that such conditions do not occur. Suddenly and uncontrolled dumping of base materials also creates obstacles that can complicate the further movement of the machine, truck, respectively. other special-purpose equipment. Again, it is necessary to use heavy machinery to remove the thus formed built-up building materials and to modify the terrain in the desired manner.

The proposed trailer is a purpose-built device whose task is to eliminate these shortcomings and ensure even spreading and layering of the underlying building materials.

The essence of the technical solution

The above requirements for even spreading and layering of the underlying building materials are ensured by a laying trailer, which can be connected behind a truck, tractor or other special-purpose towing device. This laying trailer eliminates the shortcomings of uncontrollable and uneven spreading of materials and allows direct control of the speed and amount of spreading of material.

The laying trailer consists of a self-supporting frame, which is assembled from steel profiles by means of non-detachable and detachable joints. A body made of thick-walled sheets without the possibility of tilting is firmly connected to the frame of the trailer. The frame with the body is mounted on the chassis. At the front of the vehicle there is a drawbar which is connected to the frame and is intended to be connected to the towing vehicle by means of a standard coupling mechanism.

The main role in the transport and dumping of building materials is performed by an asymmetrical "V" body. In the lower part of the body, in the "V" -shaped connection, there is an opening through which the underlying building material falls. The movement of the material towards the discharge opening is ensured by the sloping walls of the body and the use of gravitational forces acting on the material. Even and controllable pouring of the material is ensured through the pouring opening with flaps, which by their sliding movement change the size of the overflow opening, and thus regulate the volume of the poured material. Controlling the amount of bulk material allows mechanical or hydraulic control of the dampers.

The number of dampers, their shape, functional principle and layout vary depending on the version of the special-purpose connection device and the requirements for the type of building material used. The flaps are placed next to each other in the number of two or more over the entire width of the lower part of the body.

The advantages of the utility trailer design according to the utility model are obvious from the effects which are manifested externally. In general, it can be stated that the originality of the presented device lies in its ability to simplify, more controllable, more even and faster discharge of building base materials, as well as simplified operation, which is ensured by mechanical or hydraulic control of flaps. The use of a laying trailer also ensures higher productivity and easier fulfillment of the requirements for layering the underlying building materials. This vehicle therefore eliminates the main disadvantages of using trucks and various trailers with tipping mechanisms.

Examples of embodiments

The following embodiments of the technical solution are presented for illustration and not as a limitation of technical solutions.

Example 1

In this example of a specific embodiment of the subject of the technical solution, a laying trailer is described, as shown in FIG. 1, 2 and 3. It consists of a trough-shaped "V" body 1, which is inseparably connected to the self-supporting frame 2, while connecting rods 3 are inseparably mounted on the body 1. In the lower part of the body 1 the overflow opening is covered by flaps 4 slidably mounted on the body 1 itself, by sliding hydraulic motors 6 connected at one end to the flaps 4 by pin joints and at the other end to the frame 2 by pin joints. This whole structure is mounted on a chassis with one or more axles 5. The body 1 is made of sheets connected by a non-detachable joint.

Example 2

Laying trailer constructed according to Example 1, with the difference that the flaps 4 are actuated by coiled chains 8 and compression springs 7.

Example 3

Laying trailer as in Example 1, with the difference that the flaps 4 are actuated by wound steel ropes 9 and compression springs 7.

Industrial applicability

The laying trailer is preferably intended for spreading construction base materials, such as soil, gravel and the like, for the purpose of strengthening the subsoil, when working on construction sites, temporary roads and forest roads, when creating substrates for concreting and asphalt roads and large areas, creation of sidewalks, etc. Its use is mainly in the construction industry, agro-industry and the wood industry.
