DETAILED DESCRIPTION

[0019] The invention discloses a unloading cargo box of a mining dump truck, which can realize rapid unloading of materials and effectively prevent the materials from piling up in the cargo box.

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0022] Reference below Figures 1 to 4 The unloading cargo box of a mining dump truck in an embodiment of the present invention is described.

[0023] The embodiment of the present application discloses a mining dump truck unloading box, comprising: a front plate 1, a left side plate 2, a right side plate 3, a bottom plate 4 and a bottom support beam structure 5.

[0024] Among them, the bottom support beam structure 5 is of a grid-like design, which can better reduce the overall weight of the cargo box while improving the overall structural strength of the cargo box. The front plate 1, the left plate 2 and the right plate 3 are all welded and fixed to the bottom support beam structure 5. The bottom plate 4 is assembled on the bottom support beam structure 5 through a plurality of rubber springs 9. The plurality of rubber springs 9 are arranged in an array on the bottom support beam structure 5. Such a design not only enables the rubber springs 9 to provide better support for the bottom plate 4, but also the load on the bottom plate 4 can be evenly dispersed to each rubber spring 9 and transmitted to the bottom support beam structure 5 through the rubber springs 9; a vibration motor 10 is fixedly installed at the bottom of the bottom plate 4, and a proximity switch 20 is provided at the tail of the bottom support beam structure 5, and the proximity switch 20 is electrically connected to the vibration motor 10.

[0025] When the cargo box is unloading, the proximity switch 20 at the rear of the bottom support beam structure 5 will be connected due to the overall lifting of the cargo box, so that the vibration motor 10 on the bottom will start working. The vibration motor 10 drives the bottom plate 4 to vibrate, so that the materials with high viscosity and difficult to unload can be quickly separated from the bottom plate 4, thereby achieving rapid unloading and effectively avoiding the accumulation of materials at the rear of the cargo box. At the same time, since the bottom plate 4 is constantly vibrating under the action of the vibration motor 10, even in a low temperature environment, the materials with high humidity cannot freeze, and the problem of materials being easily frozen in winter is solved. In addition, the design of the vibration motor 10 can also replace the existing cargo box heating device.

[0026] In some embodiments, the proximity switch 20 can be set as an adjustable range proximity switch 20. In this way, the proximity switch 20 can be set: as the lifting angle of the cargo box increases, the range of the proximity switch 20 continues to increase, and the exciting force of the vibration motor 10 also continues to increase, which can make the residual or accumulated materials in the cargo box flow out of the cargo box quickly.

[0027] In some embodiments, for example Figure 1 As shown, in the direction from front to back, the extension amounts of adjacent rubber springs 9 decrease successively, so that the bottom plate 4 installed above the rubber springs 9 is inclined at a certain angle relative to the bottom support beam structure 5. In this way, the material in the cargo box has a tendency to flow backwards, so that the material can be unloaded from the cargo box faster during unloading.

[0028] Preferably, the inclination angle between the bottom plate 4 and the bottom supporting beam structure 5 is 1°.

[0029] In some embodiments, for example Figure 1As shown, in the direction from front to back, multiple rows of bent angle steels 41 are sequentially spaced apart on the bottom plate 4, and the heights of adjacent bent angle steels 41 are sequentially reduced, so that a certain angle is formed between the highest point connection line of the multiple rows of bent angle steels 41 and the bottom plate 4. The design of multiple rows of bent angle steels 41 can not only improve the structural strength and rigidity of the bottom plate 4, but also when the cargo box is full of materials, the grooves between adjacent bent angle steels 41 can be filled with materials to form linings, thereby helping to protect the bottom plate 4 and extend the service life of the bottom plate 4; in addition, the design of the bent angle steels 41 gradually decreasing in height from front to back can further improve the unloading efficiency.

[0030] Preferably, the angle between the highest point line of the multiple rows of bent angle steels 41 and the bottom plate 4 is 1°.

[0031] In some embodiments, the angle between the highest point line of the multiple rows of bent angle steels 41 and the bottom plate 4 is the same as the inclination angle of the bottom plate 4 relative to the bottom support beam structure 5 .

[0032] In some embodiments, for example Figure 2 As shown, the rubber spring 9 includes a spring body 91, an upper fixing seat 92 and a lower fixing seat 93, the spring body 91 is installed between the upper fixing seat 92 and the lower fixing seat 93, the upper fixing seat 92 is welded and fixed to the bottom plate 4, and the lower fixing seat 93 is welded and fixed to the bottom support beam structure 5.

[0033] In some embodiments, for example Figure 4 As shown, the cargo box as a whole adopts a trumpet design with a narrow front and wide rear, wherein the left side panel 2 and the right side panel 3 are assembled at an angle of 2°. This design makes the distance between the left and right side panels 3 of the cargo box larger as it approaches the rear of the cargo box, thereby effectively reducing the risk of material blockage at the rear of the cargo box.

[0034] In some embodiments, for example Figure 3 As shown, a plurality of vibration motors 10 are provided, and the plurality of vibration motors 10 are arranged symmetrically and spaced apart from each other, so that the vibration can evenly cover the entire bottom plate 4, avoiding the situation where the various parts of the bottom are subjected to uneven vibration, thereby further improving the unloading speed and avoiding material accumulation; the plurality of vibration motors 10 are welded and fixed to the bottom plate 4 by a fixing frame 30, so that the installation stability of the vibration motor 10 can be ensured and the vibration motor 10 can be prevented from falling off the bottom plate 4.

[0035] In some embodiments, for example Figure 1 and Figure 4As shown, the unloading cargo box of the mining dump truck also includes a height limit plate 6, and a plurality of height limit plates 6 are provided. A part of the height limit plates 6 are symmetrically arranged on the left plate 2 and the right plate 3, and another part of the height limit plates 6 are arranged on the front plate 1 to limit the height direction of the bottom plate 4, so as to effectively prevent the bottom plate 4 from deviating too much to the upper part due to vibration.

[0036] In some embodiments, for example Figure 1 As shown, the unloading cargo box of the mining dump truck further includes a front-to-back direction limit plate 7, two of which are provided, and the two front-to-back direction limit plates 7 are symmetrically arranged at the rear of the left side plate 2 and the right side plate 3 to limit the bottom plate 4 in the front-to-back direction. During the unloading process, the bottom plate 4 is subjected to a side sliding force due to the lifting of the cargo box, and the front-to-back direction limit plates 7 can be provided to effectively limit the bottom plate 4 to prevent the bottom plate 4 from sliding forward and backward.

[0037] In some embodiments, for example Figure 1 As shown, mounting seats are symmetrically provided at the rear of the left side plate 2 and the right side plate 3, and the cargo box rear tailgate 8 is assembled on the mounting seats.

[0038] Other structures and operations of the unloading cargo box of the mining dump truck according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
