[0017] In order to deepen the understanding of the utility model, the utility model will be further described in the following combined with examples and drawings, the examples are only used to explain the utility model, and do not constitute the limitation of the protection scope of the utility model.

[0018] As Figs. 1-3 Shown, header 1, auger 2, impurity removing mechanism 3, ear picking mechanism 4, chain 5, chain 6, adjusting seat 7, adjusting plate 8, second sprocket 9, V-shaped rubber belt 10, seat plate 11, support 12, shaft tube 13;

[0019] A kind of corn header bract leaf impurity removing device, including header 1, the header 1 on it is equipped with impurity removing mechanism 3, auger 2, chain 5, ear picking mechanism 4, the auger 2, chain 5 and ear picking mechanism 4 form ear picking channel, the impurity removing mechanism 3 is used to clean the sundries on ear picking channel, the impurity removing mechanism 3 includes being equipped with first sprocket, second sprocket 9, the first sprocket is coaxial with auger 2, the second sprocket 9 is fixedly connected with shaft tube 13, the shaft tube 13 is rotatably connected on adjusting support by bearing, first sprocket and second sprocket 9 are driven by chain 6, the outer wall of the shaft tube 13 is equipped with multiple impurity removing assemblies at intervals.

[0020] In the present example, the impurity removing assembly includes seat plate 11 and V-shaped rubber belt 10, the seat plate 11 is fixed on the shaft tube 13, and the V-shaped rubber belt 10 is fixedly connected with the seat plate 11.

[0021] In the present example, the seat plate 11 and the V-shaped rubber belt 10 are fixedly connected by bolt and nut.

[0022] In the present example, the adjusting support is arranged on the upper end of the two sides of the header 1, the adjusting support includes adjusting plate 8, adjusting seat 7, support 12, the adjusting seat 7 is fixed on the header 1, the adjusting seat 7 is equipped with multiple adjusting holes, the adjusting holes are arranged according to arc trajectory, one end of the adjusting plate 8 is hinged with the adjusting seat 7, and the middle section is connected with the adjusting seat 7 by means of bolt, the bolt passes through the adjusting hole on the adjusting plate 8 and the adjusting seat 7, the support 12 is used to be connected with the shaft tube 13, and the support 12 is installed on the adjusting plate 8.

[0023] It needs to be explained that before cleaning, the adjusting plate 8 is rotated to a suitable angle, the distance between the impurity removing assembly and the ear picking channel is suitable for the current working condition, then the bolt is inserted into the fixing, the power is transmitted to the chain wheel set through the stirrer 2, the shaft tube 13 is rotated, and then the impurity removing assembly is rotated.
