| 摘要 | A sidewall attachment for unloading devices which are used for unloading bulk material from a boxlike enclosure in a uniform and controlled manner in which there is included a flexible attachment for the sidewalls of the boxlike enclosure which coacts with a scraper unit to produce a scraping and rippling action which keeps the sidewalls free of bulk material. | ||||||
| 权利要求 | 1. An attachment for the surface of an unloading device for unloading bulk material which as a tendency to adhere to the surface of the unloading device comprising: a container member for receiving bulk material and having means for confining the bulk material therein; a flexible member attached to said means for confining the bulk material therein; a pusher member mounted in said container member for forcing the bulk material out of said container member, said pusher member including a pliable scraper member for sliding along said flexible member to thereby clean the flexible member as the pusher member slides along said flexible member. 1. An attachment for the surface of an unloading device for unloading bulk material which as a tendency to adhere to the surface of the unloading device comprising: a container member for receiving bulk material and having means for confining the bulk material therein; a flexible member attached to said means for confining the bulk material therein; a pusher member mounted in said container member for forcing the bulk material out of said container member, said pusher member including a pliable scraper member for sliding along said flexible member to thereby clean the flexible member as the pusher member slides along said flexible member. 2. The invention of claim 1 wherein said flexible member is spaced sufficiently from said means for confining the bulk material to produce a ripplIng action when said pusher member slides along said flexible member. 3. The invention of claim 1 including a splash beater for spreading the bulk material in an open field. 4. The invention of claim 1 including flexible members located on said pusher member to prevent said pusher member from binding in said container member. 5. The invention of claim 2 wherein said container member comprises a spreader box and said means for confining the bulk material comprises a pair of side walls each having a top and bottom. 6. The invention of claim 5 wherein each of said flexible members is sealed to the top of said side wall member to prevent moisture from entering therein. 7. The invention of claim 6 wherein each of said flexible members is spaced from said side wall by a compressible member. 8. The invention of claim 7 wherein said flexible member comprises a polymer plastic material. |
