Description

TECHNICAL FIELD

[0001] The application relates to the technical field of charging trolleys, in particular to a hopper structure and a charging trolley. BACKGROUND

[0002] In the traditional design of charging trolleys, the installation mode of the hopper generally adopts a welding type fixing method, which permanently fixes the hopper at the front end of the charging trolley. In this way, the charging trolley can only be equipped with one type of hopper, and cannot replace or select different types of hoppers according to the actual needs of different material types transported. This fixed configuration greatly limits the operation flexibility of the charging trolley, so that the operator cannot flexibly adjust the equipment to adapt to different working scenes when facing different operation requirements, thereby reducing the operation efficiency and the application range of the equipment. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at solving the above-mentioned problems and provides a hopper structure and a charging trolley.

[0004] The technical scheme of the application is implemented as follows:

[0005] In the first aspect, the application provides a hopper structure, which further comprises:

[0006] A hopper connecting frame, the front end of which is detachably connected with the hopper body, and the rear end of which is connected with a transport carrier;

[0007] A hopper push plate, which is slidably installed in the hopper body along the length direction of the hopper body;

[0008] A push plate push-pull frame, which is movably installed in the hopper connecting frame, the front end of the push plate push-pull frame is detachably connected with the hopper push plate, and the hopper push plate moves forward and backward in the hopper body through the push plate push-pull frame.

[0009] The advantages or beneficial effects of the above technical scheme at least include:

[0010] In the second aspect, the application further provides a charging trolley, the front end of which is provided with the hopper structure as described above; and the charging trolley is connected with the hopper connecting frame through a cylinder assembly.

[0011] The advantages or beneficial effects of the above technical scheme at least include:

[0012] By adopting the detachable hopper body, the operator of the factory can flexibly select a suitable hopper body according to different material types and weight requirements. For example, in a narrow environment with limited space, the operator can select a hopper with a smaller size, thereby significantly improving the maneuverability and flexibility of the charging trolley. This design enables the operator to select and replace the hopper according to the actual material conditions, thereby greatly improving the overall work efficiency. BRIEF DESCRIPTION OF DRAWINGS
