MODIFIED TRAILER FOR THE TRANSPORTATION, QUICK LOADING AND UNLOADING OF GRANULATED MATERIALS

Abstract

The present invention consists of a modified trailer for the transportation, quick loading and unloading of granulated materials, which includes an ensemble of differently sized walls that, when put together, resemble a trapezoidal prism in shape. This trailer is fitted with a hatch located on its upper wall that's used for the loading of materials, as well as a discharge hatch that's designed for a quick and loss-free unloading of said material that avoids the generation of dust which is located in its lower wall. Additionally, it is also fitted with a wheel axle and a couple of support legs with a similar configuration to conventional load trailers.

Description

PURPOSE OF THE INVENTION

The present invention provides a means of transport that specifically consists of a modified trailer for the transportation, quick loading and unloading of granulated materials, which has been generated in response to the need of transporting raw materials of diverse kinds, having a number of specific modifications that ease in every step the trailer's loading and transported material's emptying processes.

BACKGROUND

There exist a number of trailers for the hauling of materials that are well documented within the state of the art. Those commercialized under the Timpte, Wilson, and JetCo can be mentioned as examples. Relative to said conventional examples, the present invention differentiates itself, firstly, by its size, weight, shape and the fact that it is fitted with a chute that's coupled to an aperture mechanism that controls a discharge hatch by means of a manually-actioned lever that when cranked opens said hatch by means of a roller chain. This renders its opening more efficient and lessens the probability of failure by jamming. Secondly, the present trailer is fitted with a top-side covering that secures the transported materials. This covering incorporates a rectangular hatch that is used to load said trailer with the raw materials of interest, said hatch opens by means of a lever that is located in the rear part of the trailer.

DETAILED DESCRIPTION OF THE INVENTION

The present invention consists of a modified trailer for the transportation, quick loading and unloading of granulated materials, similar to a conventional trailer container, which consists of an ensemble of differently sized walls that, when put together, resemble a trapezoidal prism in shape, as is illustrated in FIG. 1. The modified trailer has a lower wall as a base (1), two same-sized lateral walls (2), an upper wall (3) smaller in size than the lower one, and same-sized forward (4) and rear (5) walls. The trailer's shape and construction materials allow for a lightweight ensemble that permits the hauling a greater amount of materials than existing trailer containers.

The trailer has a double axle (6) for wheels, located at its lower wall, as well as a pair of metallic support legs (7), perpendicular to said wall's surface, that are located near the longitudinal end opposite to the double axle, similar to a conventional trailer's configuration. These legs are necessary in order to support the present trailer when it is not docked to a truck.

The trailer's upper wall is completely covered by the same material that the whole trailer is made of There is a rectangular opening which is located at said upper wall's central part which is covered by a hatch (8). Said hatch can be designated as the loading hatch, and is used to load the trailer with the material intended to be hauled. It is opened and closed manually by means of a crank (9), which is located over the trailer's rear wall and has a longitudinal extension (10) that transmits the crank's motion to the hatch in order to open or close it.

This loading hatch is hooked to a couple of safeties (11) in order to prevent its opening when the trailer is being hauled or to prevent its closing during the loading process. There is a stairway located on the forward wall that can be used to access said loading hatch. There is a layer of diamond plate, preferably made of chromed aluminum, located next to the hatch that can be used to prevent the operator from falling when standing on top of the trailer and next to the loading hatch.

There is a chute attachment (12) located at the center of the lower wall that resembles an upside-down trapezoidal prism in shape. This attachment is fitted with a hatch (13) which is located at its inferior end, through which the materials contained within the trailer are unloaded. This discharge hatch is manually opened and closed by means of a lever (14) that is placed towards the left end of the hatch and is fastened with a hook (15) that acts as a safety. When the lever is turned, a conventional roller chain mechanism (16) that is placed on both sides of the discharge hatch helps it slide to an open or closed position.

Both the forward (4) and rear (5) walls have been fitted in their internal faces with nets (17), preferably made of metal, in order to protect the surface of said walls from an impact with any object during the hauling of the trailer.

The trailer's interior has two extra walls that extend from the upper front and upper rear edges towards the chute, with a 45-degree inclination and an overall shape resembling an upside-down trapezoidal pyramid. Said walls end where the chute begins, and achieve a hermetic space with a greater storage capacity and security than that in similar trailers.

A greater efficiency and security in the transportation of materials, as well as a quicker, safer and easier gravity-assisted discharge of said materials is achieved as a product of the ensemble's obtained shape. Discharge rates of, for example, 54,000 pounds of granulated material in 8 to 10 minutes can be achieved on a fully loaded trailer, which represents approximately a third of the time similar competing models take to perform the same operation. The present configuration of loading and discharge prevents in great measure the generation of dust, which is highly harmful towards human health and equipment infrastructure.
