[0002] In industrial and agricultural production, pellet materials are widely transported, stored, processed, mixed, and blended. These materials include grain, coal, slag, sand, gravel, and plastics. Currently, traditional loaders are used for most of the transportation and storage processes. Loading and unloading with traditional loaders relies entirely on manual operation, and repetitive manual movements can easily lead to fatigue. In particular, during the transport of pellet materials back to the warehouse, loaders are used in conjunction with transport vehicles to stack the pellets in the storage area. This creates a situation where transport vehicles and loaders work alternately, which can easily lead to collisions. Furthermore, the back-and-forth operation of transport vehicles and loaders within the storage area hinders the installation of automated pellet handling equipment within the warehouse. The constant stacking of pellets by loaders while transport vehicles load and unload, while also incurring significant fuel consumption and labor costs. Most conventional loaders currently use diesel fuel, and the stacking process produces significant exhaust emissions that pollute the environment. This can cause significant contamination of grain, especially during grain stacking operations.

[0020] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, this should not be understood as limiting the scope of the present invention to the following embodiments, and all technologies implemented based on the present invention fall within the scope of the present invention.

[0021] Unless otherwise specified, in the description of the specific embodiments of the present invention, the terms indicating the orientation or positional relationship, such as "upper", "lower", "left", "right", "center", "inside", and "outside", are based on the expressions of the orientation or positional relationship shown in the accompanying drawings, or are the orientation or positional relationship in which the invented product / device / apparatus is placed when it is conventionally used. These terms of orientation or positional relationship are merely for the purpose of facilitating the description of the scheme of the present invention or simplifying the description of the specific embodiments to facilitate the rapid understanding of the scheme by technicians, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship, and therefore should not be understood as limiting the present invention.

For example, they may refer to fixed connections, detachable connections, or integral connections. They may be welded, riveted, bolted, threaded, or other commonly used connection methods in the art. Such connections may be mechanical, electrical, or communicative; they may be direct, indirect via an intermediate medium, or internally connected between two components.

[0026] In the related art, traditional loaders are used for loading and unloading in most working conditions during the entire process of transportation or storage. The loading and unloading of traditional loaders is completely dependent on manual operation, and manual operations that repeat the same action over and over are very likely to cause work fatigue. Especially in the process of transporting pellets back to the warehouse, it is necessary to use a loader to cooperate with the transport vehicle to stack the pellets in the storage yard, and there will be a scene where the transport vehicle and the loader work alternately, which is very likely to cause a production safety accident of a vehicle collision; at the same time, the transport vehicle and the loader work back and forth in the storage yard, which hinders the installation of automatic pellet output equipment in the storage yard. The transport vehicle enters the warehouse for loading and unloading, and the loader keeps stacking pellets, which will also generate a considerable amount of fuel consumption and labor costs. Most of the traditional loaders currently used are powered by diesel, and the loader will also produce a large amount of exhaust gas that pollutes the environment during the stacking operation.
