    The invention relates to a snow plow. The invention relates in particular to a snow plow, the structure of which can be modified according to the intended use.
    Snow clearing and removal from property yards and walkways must be done with equipment that is best suited for a variety of locations. This causes difficulties in designing and manufacturing snow plows to meet customer-specific needs. Customer needs vary, for example, between the working width of snow plows and other dimensions and other features. Plows to be mounted behind or in front of the implement, plows with adjustable working width, plows with swiveling or fixed blades are required. Frame-driven implements require machines that are suitable for their construction and working methods, etc. Contractors do not find snow plows suitable for different jobs in the manufacturers' offer, which means that they have to acquire more equipment. In this case, the utilization rate of the equipment easily decreases and the costs increase. The present invention provides a snow plow that is structurally modifiable. The snow plow consists of a central frame on which - alternative subassemblies can be mounted with a mechanical joint. A mechanical connection is, for example, a detachable screw connection, a pin connection or a form-fitting connection. In connection with the center frame, in front of the direction of travel, there are first N fastening means in front of the snow plow, with which the snow plow can be fastened behind the implement. The center frame-> 25 also has other fastening means with which the snow plow can be fastened to the implement to the front. Both fastening means are mounted by a detachable mechanical connection, whereby, for example, when fastening a snow plow to the front side of the implement, the first fastening means are not installed at all. At both ends of the central body there are connecting members with which various extensions can be attached to the central body to achieve the desired working width. Alternative subassemblies such as fixed wings, widening wings, pivoting wings and alternative combinations thereof can be attached to the central body or these extensions.
    The following are examples of snow plow applications in which the snow plow is secured by other attachment means to pivoting or fixed attachments on either the front or rear of the implement.
    1. The center frame alone acts as a dozer blade
    2. Middle body with fixed wings, so-called. grabber model
    3. Middle frame extended with extensions and fixed wings (grab model)
    4. Middle frame with widening fixed wings (grab model)
    5. Middle body with widening fixed wings extended by extension pieces (grab model)
    6. Middle frame with swivel wings, so-called. grabber model
    7. Center frame extended with extensions and swivel wings (grab model)
    8. Center frame with widening swivel wings (grab model)
    9. Center frame with widening swivel vanes extended with extensions (grab model) The following are examples of snow plow applications in which the snow plow is attached to the swivel or fixed attachments of the implement at the rear of the implement by first attachment means.
    10. The center frame alone acts as a dozer blade
    11. Central body with fixed wings, so-called. grabber model
    12. Center frame extended with extensions and fixed wings (grab model) N 13. Center frame with widening fixed wings (grab model)> 25 14. Center frame with widening fixed wings extended with extensions (grab Model) ia An alternative combination of L is attached to the pivoting attachments of the front boom of the implement by means of other attachment means. This snow plow includes N a central frame with a working width of 2400 mm, 300 mm extension pieces connected to the ends of the central frame and even widening parts with swiveling wings. In this case, the working width of the plow can be adjusted between 3000-4800 mm.
    The central frame consists of a curved chest plate corresponding in length to the working width, supported on the back by cut-out support plates. Arranged on the back of the breast plate is a female, casing guide with conductive material on the inner surfaces. The widening wings have an actuator with said female guide (the first end of which is fixed to the central body and the second end of which is fixed to the wing. A front blade body is provided with a strong blade body plate with a plow blade attached to the lower part thereof. there are brackets for the first fastening means on the front and second fastening means for fastening the front of the snow plow on the rear side.
    Modern methods have been utilized in the design and manufacture of snow plow structures, in which the parts of the assemblies are manufactured precisely on the basis of 3D files. In this case, it is possible e.g. control the positioning of the parts of the assembly relative to each other by applying form-fitting joints, which requires less other joining methods, such as welding. At the same time, the need for guiding assembly tools such as welding jigs is reduced. Since the joints of the main parts are mechanical joints, such as simple screw joints, it is possible to cost-effectively implement a relatively large number of product variations with a limited number of subassemblies.
    The snow plow and its interchangeable subassemblies are light in structure, because the material is placed as cheaply as possible in terms of stresses.
    S> 25 The object of the invention is to provide efficient industrial production methods a snow plow that is structurally modifiable. The invention eliminates the drawbacks of the prior art and provides a snow plow which is simple in construction and inexpensive to purchase.
