Abstract

The invention relates to a semi-trailer which is used to transport loose or packed and palletised products. The inventive semi-trailer comprises: a prism-shaped structure which is enclosed by side walls, a roof and a front element which are all laminated; a rear part with access doors; and a floor comprising discharge hoppers which are closed by means of hatches. The roof comprises holes which are used for loading loose products. Internally, the front and rear parts comprise two planes which are inclined towards the floor or the roof in order to convert the trailer into a hopper for loose or palletised products. The semi-trailer comprises a front rest skid and, moreover, said trailer can also comprise several rolling axles according to the loading capacity thereof.

Description

 SEMI-TRAILER HOPPER AND BOX

DESCRIPTION OF THE INVENTION BACKGROUND

In Mexico, as well as in other countries, there are vehicles that allow transporting land supplies and items that economic activity demands. In this sense in the market there are units for cargo transport in general known as containers, dry box semi-trailers or box-type wagons in which different products are transported protecting them from the weather and external conditions, the designs and dimensions vary according to to the needs of the users.

There are also semi-trailers "'hopper or hopper type wagons which are intended for the transportation of bulk products such as grains, seeds, flours, cement, etc. that are not packaged for transportation. These vehicles have hatches in the roof for loading the aforementioned materials, as well as gravity discharge gates on the floor.

From these two vehicles the idea of a new unit that allows transporting products or items previously packaged or packaged, as well as bulk products, can be seen.

From this idea I undertook the design calculation and engineering for the manufacture of this vehicle; so below I detail the novelty of the semi-trailer "Hopper-box"

ADVANTAGES OF THE SEMI -TOLVA-CAJA "REMOVAL" This unit has as main objective to increase the productivity of those who are dedicated to transport, the hopper-box semi-trailer allows to be used as a hopper for transporting grains, seeds, flours, cement, etc. . for which it has side walls, front and rear wall in the form of an inclined plane, roof with cargo hatches and at the bottom one or more gravity discharge cones with guillotine gates. This whole assembly is hermetically assembled, which allows bulk products to be transported safely.

Unlike the existing units in the market (hoppers) the hopper-box once unloaded the products in bulk can be used as a semi-trailer dry box simply by removing the inclined planes (front and rear wall) towards the ceiling or floor allowing the entrance of the different products that are transported in closed box semi-trailers, which can be loaded with forklifts, skateboards or manually.

In this way the benefits offered by the semi-trailer hopper-box are many, we cite some of these advantages: 1. It allows round trips, in a sense you can take bulk products that are generally transformed into other materials Premiums or finished products that are generally packed or packaged, or other transportation opportunities may simply be contacted.

2. Cost reduction for 100% use of the equipment (truck and hopper-box).

3. Reduction of environmental pollution.

4. Reduction of traffic on roads and cities.

5. A single investment to transport bulk and packaged products.

6. Different alternatives of manufacturing materials, steels, aluminum or composite materials.

CARACTERÍSTICAS DEL SEMI-REMOLQUE "TOLVA-CAJA"

CHARACTERISTICS OF THE SEMI-TRAILER "TOLVA-CAJA"

With reference to the drawings described above, the hopper-box semi-trailer is a vehicle that can be used for two purposes, the first one can be used as a hopper for transporting bulk products and the second function as a closed box type trailer.

Said unit is manufactured by two stringers or lateral embroideries placed on the top and bottom of each of the sides of the unit (Figs. 2, 3 Part No. 9, 10) these two stringers are spaced by several structural elements (Figs .2, 3, 9 Part No. 1) spaced according to the required load capacity, subject to these horizontal elements (Figs. 2, 3 Part No. 9, 10) and vertical elements (Figs. 2, 3, 9 Part No. 1) carries the lamination of the sides (Figs. 2, 3, 7, 8, 9 Part No. 2) which, in addition to containing and protecting the products transported inside the unit, functions as A structural element, in addition to the two sides, has a front wall on the outside (Figs. 1, Part 4 3), as well as a rear frame with doors (Figs. 1, Part 5 No. 12) and defense (Fig. .5 Part No. 13) As for shocks, on the upper part there is a cover made of aluminum foil or composite materials (Fig. 1 Part No. 15) qu and join the upper edges (Figs. 1, 2, 3 Part No. 9) the upper front edge (Figs. 1, 4 Part No. 11) in addition to the rear frame (Figs. 1, Part 5 No. 12), this roof lamination (Fig. 1 Part No. 15) serves the same purposes as the side lamination (Figs. 2, 3, 7, 8, 9 Part No. 2) on the roof has one or more gates for bulk loading (Figs. 1, 2, 3 Part No. 16) and in the surroundings of these hatches it has non-skid aisles (Fig. 1 Part No. 14) to access all the hatches. These vehicles can carry one, two or three axles (Figs. 1, 2, 7, 8, 11, 12 Part No. 6) is equipped with kidneys (Figs. 1, 2, 7, 8, 11, 12 Part No. 7) and tires (Figs. 1, 2, 7, 8, 11, 12 Part No. 8) according to the number of axles and load capacity, it has vertical supports known as support skates (Figs. 2, 3, 4, 7, 8, 11, 12 Part No. 5) for when the unit is not coupled to the drive unit, at the bottom of the unit coupled to the lower edges (Figs. 2, 3 Part No. 10) is the vehicle floor (Figs. 9, 10, 13 Parts Nos. 20,21) below the floor of the hopper section (Figs. 9, 10, 13 Part No. 21) carries the cones or bulk discharge hoppers (Figs 2, 3, 6, 7, 8, 11, 12,13 Part Nos. 17) and in the lower part of the cone it has a guillotine-shaped gate (Fig. 13 Part No. 18) which is actuated by turning a spindle (Fig. 13 Part No. 19). Inside the unit it has two walls that are placed as inclined planes one in the front of the unit (Figs. 11, 12 Part No. 22) and another in the back of the unit (Figs. 11, 12 Part No. 23) these inclined planes or walls can be removed towards the ceiling, or towards The floor, by counterbalance mechanism (Figs. 11, 12, 13, 14 Part No. 26), this mechanism consists of the following parts: main arrow (Fig. 14, Part No. 27), conical pulley (Fig. 14 Part No. 29), to increase power in relation to the advance of the steel cable (Fig. 14, Part No. 31), arrow bearings (Fig. 14 Part No. 30), and torsion spring (Fig. 14 Part No. 28), when removing these walls or inclined planes are those that allow this semi-trailer to give it the double function of hopper and box. Moldings are found on the sides (Figs. 7, 8, 11, 12 Part No. 25), so that the inclined planes can be supported consistently, on the sides of the unit there are also spacers (Fig. 7, 8, 11 , 12 Part No. 24) that allow stabilizing the load when the unit is being used in the cash mode.
