The material transport vehicle is used to transport the material output by the material output belt 9 to the designated destination. Since the material output point of the material output belt 9 is fixed, it is not conducive to evenly distributing the material on the longer transport vehicle . The material conveying device provided on the carriage 1 can move along the length direction of the carriage 1, and can be in various forms, such as a small hopper car, a sloping plate with a large slope (the material can slide on the sloping plate by its own gravity) and fall into the carriage 1) or the belt conveyor described below, therefore, the material output from the material output belt 9 can be received and released at different positions above the carriage 1, so that the material can be more evenly distributed in the carriage 1 in. In this case, the carriage 1 has a greater length, and manual material turning can be avoided, which saves manpower and improves work efficiency.

Preferably, the material conveying device is configured as a belt conveyor 2 extending along the length direction of the carriage 1 .

In addition, the carriage 1 includes a plurality of sections connected in sequence. Because the material output point of the material output belt 9 is fixed, even if a multi-section box section is connected, it is difficult to load material on other box sections. Because the utility model adopts the material conveying device, therefore, the material received from the material output belt 9 can be transferred to other box sections, which improves the loading capacity of a single transportation. Similar structures such as connecting beams or guide rails may be arranged between adjacent box sections to carry the material conveying device and allow the material conveying device to move between different box sections.

Further, the material conveying device includes an inclined belt conveyor 21 and a flat belt conveyor 22 capable of sequentially conveying materials, and the box section includes a first box section and a second box section, wherein the inclined belt conveyor 21 and the The first box section is slidingly fitted and located at one end of the first box section, one end of the flat belt conveyor 22 is slidingly fitted with the other end of the first box section, and the other end of the flat belt conveyor 22 is connected to the second box section of the other section. section slip fit. As shown in Figure 1, the length of the inclined belt conveyor 21 can be less than the first case section and is positioned at the bottom of the discharge end of the material output belt 9, and its belt can move bidirectionally, and the material received can be dropped into the place at both ends. One end of the flat belt conveyor 22 can be located on the first box section, and the other end is located on the second box section, so it can receive the material delivered from the inclined belt conveyor 21 and Drop the material onto the second case section.

In addition, the high end of the inclined belt conveyor 21 faces the flat belt conveyor 22 . When the inclined belt conveyor 21 is feeding materials at the high end, one end of the flat belt conveyor 22 can be adjacent to the high end of the inclined belt conveyor 21, and the materials delivered by the high end of the inclined belt conveyor 21 have a certain horizontal speed and can fall on the On the flat belt conveyor 22. When it is necessary to put materials on the first box section, the flat belt conveyor 22 can be spaced apart from the inclined belt conveyor 21, and the materials received by the inclined belt conveyor 21 can be placed in the first box through the high end or the low end. section; when materials need to be loaded on the second box section, materials can be delivered to the flat belt conveyor 22 through the high end of the inclined belt conveyor 21 and finally placed on the second box section. Moreover, the belts of the inclined belt conveyor 21 and the flat belt conveyor 22 can be supported by idler rollers 10 to ensure that the belts can transport materials stably.

As shown in Figures 2 and 3, the belt conveyor 2 used in the material transport vehicle of the present utility model mainly includes two forms of inclined belt conveyor 21 and flat belt conveyor 22, wherein the inclined belt conveyor 21 not only has The function of putting the received material on the car box 1, and the material can be transferred to another belt conveyor through the higher end, that is to say, the material can be transferred multiple times through a plurality of inclined belt conveyors 21 adjacent to each other , so the material can be transferred to different box sections; the flat belt conveyor 22 is generally only used for the last section of the box section, and is not used to transfer materials to the next-level belt conveyor; of course, if the adjacent Forming a suitable height difference between the flat belt conveyors 22 can also achieve the purpose of transferring materials step by step, but such a height space also puts forward higher requirements.

In addition, the flat belt conveyor 22 has a straight line running state and a curved running state. In the curved running state, the maximum offset of the flat belt conveyor 22 relative to the straight running state is 200 mm. The two ends of the flat belt conveyor 22 are respectively located on two box sections, and when the material transport vehicle is in a transition state, the first box section and the second box section are offset relative to each other, and the flat belt conveyor 22 is set to allow such an offset, and the maximum offset is 200mm.

In addition, the carriage 1 is an open-top car with an upward opening; or, the carriage 1 is provided with a lid, and the lid is configured to be opened when the material conveying device is filling the carriage 1 with materials, and to cover the carriage 1 after the materials are filled. When the loaded material can accommodate the carriage 1 more stably, the form of an open car can be used, and when the material is easy to spill during transportation, the carriage 1 with a lid can be used, and the installation form of the lid is required by those skilled in the art. well-known, and will not be described in detail here.

As mentioned above, for the requirement of loading at different positions of the carriage 1, the material conveying device can move on the carriage 1, specifically, guide rails 5 are respectively arranged on the top surfaces of the two side walls of the carriage 1, and the material conveying device The conveying device cooperates with the guide rail 5 through the rollers 7 formed at the bottom thereof to move on the carriage 1 . The cooperation between the roller and the guide rail is a relatively common form in this field. Of course, the form of sliding cooperation can also be adopted, but this also puts forward higher requirements on the frictional resistance treatment of the sliding cooperation.

Further, a bracket 4 is formed at the bottom of the material conveying device, the bracket 4 includes two support plates 3 arranged at intervals, and the roller 7 is arranged between the two support plates 3 . The bracket 4 can be used to support the belt conveyor 2 mentioned above, and a roller mechanism can be installed so as to move on the guide rail 5 of the carriage 1 .

In addition, as shown in Figure 4, the top surfaces of the two side walls of the carriage 1 are respectively provided with guide rail support beams 6 for carrying the guide rails 5, and a plurality of first rail support beams 6 arranged at intervals along the length direction are formed on the guide rail support beams 6.
