The collection hopper of cotton harvesting machine
Technical field
The present invention relates to the collection hopper of a Cotton Harvesters.
Background technology
Cotton is that the cultivated area of the important economic crops, particularly Xinjiang of China is very large, but the results of cotton perplex a difficult problem for Cotton in China plant husbandry for a long time, and mechanized harvest cotton has become the trend of Future Development.Cotton, after being gathered by cotton, is first deposited in casing, and then unloads from casing by cotton harvesting machinery.The collection hopper of current cotton harvesting machinery is after cotton is filled, and need manually to be unloaded by cotton, inefficiency, labour intensity is large.Also have sensible self-unloading mode to unload cotton, but the door of switch collection hopper still need manually to intervene, have impact on the operating efficiency of cotton picker.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of can to the collection hopper of the cotton harvesting machine that the cotton of collection hopper automatically unloads after cotton collection is full.
The object of the invention is to be realized by following structure: comprise underframe (1), bracing frame (2), casing (4) and back carriage plate (4-1), described casing (4) by pinned connection on bracing frame (2), simultaneously, elevate a turnable ladder oil cylinder (3) is provided with between bracing frame (2) and casing (4), the top of back carriage plate (4-1) to be connected with casing (4) by hinge and to be provided with back carriage plate opening mechanism (6), this back carriage plate opening mechanism (6) comprises push rod (6-1), the middle part of push rod (6-1) is articulated with on bracing frame (2) by a support (6-2), the upper end of push rod (6-1) is connected by bearing pin with back carriage plate (4-1), the casing (4) of the relevant position, bottom of described push rod (6-1) is provided with chute (6-3), and can slide in push rod (6-1) bottom in described chute (6-3), the casing (4) at back carriage plate (4-1) lower edge place is provided with back carriage plate retaining mechanism (7), this back carriage plate retaining mechanism (7) comprises latch hook (7-4), this latch hook (7-4) leading section is in hooking shape, latch hook (7-4) middle part is upper and can pin joint be that axle swings in casing (4) by hinge, the hook of latch hook (7-4) front end is made to pin or to decontrol back carriage plate (4-1), the rear end of latch hook (7-4) is provided with pull bar (7-3) and connecting lever (7-2) successively, pull bar (7-3) is connected by bearing pin one end with connecting lever (7-2), connecting lever (7-2) middle part also can pull pull bar (7-3) while the rotation of this bearing pin by pinned connection in casing (4) is upper, the corresponding site of the bracing frame (2) of connecting lever (7-2) the other end is provided with collision block (7-1).
As improvement, between push rod (6-1) upper end of described back carriage plate opening mechanism (6) and back carriage plate (4-1), be preferably provided with connecting rod (6-5), to cushion; Casing (4) front portion also can be provided with front wicket, and during cotton picker operation, staff opens front wicket and can enter hopper and can tread cotton in casing (4).
Compared with prior art, the present invention automatically can unload the cotton of collection hopper after cotton collection is full, substantially increases operating efficiency, solves the problem that when manually unloading, labour intensity is large simultaneously.
