[0020] When worker carries raw material bag and adds material into hopper, footboard 4 is stepped on to open hopper cover 3, without taking out hand to open hopper cover 3, it is very convenient to use.

[0021] In a preferred scheme of the utility model, hopper body 2 or support 1 is provided with hopper cover mounting seat 5, and one side of hopper cover 3 is fixed with swing rod 31 hinged with hopper cover mounting seat 5. Transmission mechanism includes crowbar 61, connecting rod 62 and first fixed seat 63 fixed relative to support 1, footboard 4 is fixed at the front end of crowbar 61, the middle part of crowbar 61 is hinged with first fixed seat 63, the rear end of crowbar 61 is hinged with the lower end of connecting rod 62, and the upper end of connecting rod 62 is hinged with swing rod 31. Generally, support 1 and first fixed seat 63 can be directly installed on floor 81, and can be installed and fixed on the base of bottom surface.

[0022] Crowbar 61, connecting rod 62 and swing rod 31 jointly constitute double-crank rod mechanism or crank rocker mechanism. When crowbar 61, connecting rod 62 and swing rod 31 constitute double-crank rod mechanism, crowbar 61 and swing rod 31 both act as crank. When crowbar 61, connecting rod 62 and swing rod 31 constitute crank rocker mechanism, crowbar 61 acts as rocker, and swing rod 31 acts as crank.
