PURPOSE:To simplify both construction and operation by installing the lower case of a grain lifter which should be fitted in a pit, and a hopper whose top end is positioned in said pit, in a main frame which is removably fitted to the top edge part of said pit. CONSTITUTION:The lower case 5 of a grain lifter 4 which should be fitted in the inside of a pit 1 and a hopper 6 whose top end is positioned in the pit 1 while whose lower end is opened to the lower case 5 so as to feed grains, are installed in a main frame 3 which is removably fitted to the top edge part 2 of a pit 1. That is, grains fed into the hopper 6 are lifted through the grain lifter 4, and the lower case 5 of the grain lifter 4 and the hopper 6 are constructed in an integrated form with the main frame 3 so as to be fitted in the pit 1. Thereby, fitting and removing operation in and from the pit 1 is simplified, the bottom end of the case 5 is not directly mounted on the bottom face of the pit thereby being hardly subjected to humidity, it is not necessary for a worker to enter the inside of the pit 1 without requiring a large space for the pit, and both the construction and operation are simplified and the device is economical. |
