In the process of shearer running, the coal plate comes into contact with the left and right supporting sliding shoes in the middle trough and the left and right walking wheels are meshed with the pin rails of the middle trough.
Therefore, there are two meshing relationships, namely, the coupling relationship between the walking wheels and shape of pin rails and that between the supporting sliding shoes and coal plate.
(6) The key points of two walking wheels are determined by the key point coordinates of the two supporting sliding shoes, and the shearer body pitch angle is determined on the basis of the left and right walking wheels and pin rails.
They also have an intact walking wheel, used for wool spinning; a very large warping board; bobbin winder; wool carders; flax hackles; and jig for making string heddles.
But in a more recent development, he has started to use "walking wheels" in the last month.
Also, the wheels were simply described as "Two walking wheels, 48 inches high," but text did not identify whether they were front-driving wheels or rear-driving.
Ms Linton said: "He tried a set of walking wheels last year, but they just fell apart.
