Title: Earth removal plate device of trencher
Inventor: YOKOMAKU YOSHIRO
IPC: E02F7/00
Filed: 1994-06-10
Abstract: PURPOSE:To improve work efficiency by mounting a main conveyor and auxiliary conveyor which rotate downwardly to an earth removal plate onto which blocks of earth are dropped from an excavation bucket and specifying an attaching angle of the main conveyor. CONSTITUTION:When a chain 33 is rotated in a wet field or the like, an excavation bucket 34 flings off forward scooped earth at the highest point. Next light blocks of earth are thrown far away and attach to the vicinity of the forward end of an earth removal plate 41 and also fall down under their own weight so that the blocks are drawn downward by a main conveyor 42 since they are viscous and drop onto the side of an excavated trench. The flying distance of heavy blocks is short and hence they rapidly fall onto the vicinity of the rear end of the plate 41. The blocks are carried downward by an auxiliary conveyor 43 and fall down onto the side of the groove. Further the end of the plate 41 is oriented so as to intersect the flying direction of the earth and a conveyor inclined at a bevel of 3-60 deg. is disposed below the plate 41. As a result, clogging can be prevented and scraping and washing of attached earth is not required, facilitating execution of work.
