Because the outer flexible connecting sheet 181 and the bottom flexible connecting sheet 182 are made of flexible materials, such as flexible rubber or flexible polymer plastic materials, when the movable baffle 08 is in a vertical state in a buckling manner, the outer flexible connecting sheet 181 and the bottom flexible connecting sheet 182 are in a folded state, and the action of buckling and opening cannot be influenced.

For prior art's hopper and movable baffle hinged joint mode, flexible material makes movable baffle 08 can be for the vibration of hopper small-amplitude under the drive of external force, and the material can be more smooth and easy output under the condition of movable baffle 08 vibration, avoids the material bite in movable baffle 08 department. Specifically, on the basis of the flexible connection between the hopper and the movable baffle 08, the vibrating motor 183 is arranged on the side, far away from the hopper, of the movable baffle 08, the vibrating motor 183 is driven by a hydraulic control system of the material vehicle to drive the movable baffle 08 to vibrate at high frequency, and materials in the hopper 06 are driven to vibrate when conveyed to the movable baffle 08, so that the smoothness of material output is improved, and the material conveying device is particularly suitable for occasions with small inclination of the hopper 06. In some embodiments of the present invention, the movable baffle 08 has a feeding port 12 and a feeding pipe 14 with closed openings, the feeding port 12 is disposed to block the material, and the vibration motor 183 is disposed to counteract the blocking.

Fig. 11 is a schematic diagram of a hydraulic control system of the solid material feeding vehicle. As shown in the figure, for example, in the angle adjusting mechanism, the height adjusting mechanism 05, the turnover adjusting mechanism 07, the opening and closing adjusting mechanism 09, the flow rate control part 13 and the length control mechanism 15 of the solid material feeding vehicle, which are hydraulically driven, the linear cylinder is subjected to reversing control through a reversing valve, so that the extension and retraction of the movable rod of the linear cylinder are realized; the motor used is controlled by a reversing valve to change the direction of the output shaft, and the vibration motor 183 is driven by a hydraulic control system. In the hydraulic machine, the reversing control of the linear cylinder and the motor is a technique mature in the industry, and the hydraulically driven vibration motor 183 is also a mature technique, and therefore, a detailed description thereof is omitted.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
