Example Embodiment

[0022] Examples, as attached figure 1 And figure 2 As shown, a corn harvester ear picking roller includes a roller 3, the roller 3 is sheathed with a roller shell 9, and the roller shell 9 is provided with a picking device for picking ears.
[0023] The picking device includes a roller rack 4', which is spirally wound around the outer surface of the roller housing 9, and the roller rack 4'extends to a position close to the end of the roller housing 9, The roller rack 4 ′ is composed of a guide part 10 and a connecting part 11. The connecting part 11 is provided with a plurality of roller teeth 4. The roller teeth 4 are uniformly arranged on the connecting part 11, and the guide part 10 is not provided with roller teeth 4.
[0024] The guide portion 10 occupies 1/3 of the length of the roller rack 4'; the end of the roller 3 close to the guide portion 10 is connected with a tower head 1, the roller 3 has a sleeve portion 7', and the tower head 1'is sleeved in the sleeve Outside the connecting portion 7, a bearing 8 is provided between the sleeve connecting portion 7 and the roller housing 9, and the bearing 8 is connected to the bearing seat 2.
[0025] A number of auxiliary broaches 5'are fixed on the outer wall of the roller shell 9, and the auxiliary broach 5'is arranged at a position close to the roller teeth 4; the auxiliary broach 5'is elongated; The auxiliary strong broach 5 is arranged to protrude from the roller shell 9; the cross section of the auxiliary strong broach 5'is semicircular; the tower head 1'is a stubby truncated cone shape; the length of the tower head 1' The diameter of the top circle of the tower head 1'is 35.5 mm, and the diameter of the bottom circle of the tower head 1'is 68 mm.
[0026] When the picking roller in this embodiment is used, the roller rack 4'is not provided with roller teeth 4 at the position close to the tower head 1', so that the smooth roller rack 4'plays a guiding role, so that the The feeding effect is good, avoiding the blockage of stems and ears, thereby avoiding downtime; the auxiliary broach 5'beside the roller teeth 4 increases the friction when pulling the stems and improves the efficiency of pulling the stems; the tower head 1' The moment of inertia is small, the operation is smooth, the failure rate is low, and it is not easy to damage.
