Detailed Description
Preferred embodiments of the present utility model are described in detail below with reference to the attached drawing figures, which form a part of the present utility model and are used in conjunction with the embodiments of the present utility model to illustrate the principles of the present utility model.
Example 1
The embodiment provides a loading ration balance, see fig. 1 through 3, including structure 1, ration storehouse 2, check weight 3, lift cylinder 4, flexible shell fragment 5, hang rope 6 and warning ball 7, the top of structure 1 is located to ration storehouse 2, the below of locating ration storehouse 2 is hung to the cylinder body of lift cylinder 4, check weight 3 hangs the output of locating lift cylinder 4 through bolt 8, the stiff end and the lateral wall fixed connection of structure 1 of flexible shell fragment 5, the suspension end of flexible shell fragment 5 is unsettled, the suspension end of flexible shell fragment 5 is hung through hanging rope 6 to warning ball 7, when check weight 3 is in the promotion state, lift cylinder 4 is in the shrinkage state, bolt 8 and the suspension end butt of flexible shell fragment 5, make flexible shell fragment 5 upwards crooked and drive and hang rope 6 and warning ball 7 upward movement.
In the process of weighing materials, once a system fault or human error occurs, the lifting oil cylinder 4 drives the check weight 3 to be in a lifting state, at the moment, the output end of the lifting oil cylinder 4 is contracted upwards and drives the bolt 8 to move upwards, when the bolt 8 contacts with the flexible elastic sheet 5 and continues to move upwards, the flexible elastic sheet 5 can bend upwards under the action of the bolt 8, and then the hanging rope 6 and the warning ball 7 can be driven to move upwards.
Compared with the prior art, the loading ration balance that this embodiment provided sets up flexible shell fragment 5 on the motion path of bolt 8 to hang at the suspension end of flexible shell fragment 5 and establish suspension rope 6 and warning ball 7, through the setting of warning ball 7, drive the motion of check-up weight 3 with lift cylinder 4 and turn into the motion of warning ball 7, because the position of warning ball 7 is lower, operating personnel can clearly see warning ball 7 upward movement to can in time discover that check-up weight 3 promotes, reduce the condition emergence because the weight deficiency that check-up weight 3 promoted causes.
For the structure of the structural frame 1, specifically, the structure comprises a top frame and a vertical supporting column, one end of the vertical supporting column is fixedly connected with the top frame, the other end of the vertical supporting column is installed on a mounting surface (such as the ground), the quantitative bin 2 is erected on the top frame, and the flexible elastic sheet 5 is arranged on the vertical supporting column.
In the foregoing loading scale, the number of the lifting cylinders 4 is 4, and correspondingly, the number of the flexible elastic sheets 5 and the number of the vertical support columns are also 4, which are in one-to-one correspondence.
For the structure of ration storehouse 2, in order to be convenient for arrange the material, it includes the main storehouse body, transition storehouse body and the unloading chute that connect gradually along the material direction of motion, and the shape of main storehouse body and unloading chute is the cylinder barrel, and the shape of transition storehouse body is the round platform barrel of inversion, and the diameter of main storehouse body is greater than the diameter of unloading chute.
In order to be able to ensure that the height of the warning ball 7 is low enough for the operator to clearly see the movement of the warning ball 7, the length of the suspension cord 6 is, for example, 3-5 m.
