Wherein, the bottom in the feeding hopper 102 is equipped with and divides storehouse board 1021, and initiative ejector pad 401 and driven ejector pad 402 are located the left and right sides of dividing storehouse board 1021 respectively, the inside grafting of curb plate of feeding hopper 102 has leak protection closure plate 1022, and the outside of leak protection closure plate 1022 is equipped with leak protection top spring 10221, the both ends of leak protection top spring 10221 are fixed connection respectively in the outside of leak protection closure plate 1022 and the outside of feed frame 202, this design makes the bottom in the feeding hopper 102 separated into two working spaces by dividing storehouse board 1021, initiative ejector pad 401 and driven ejector pad 402 can work independently in two working spaces respectively, mutual noninterference, it is nimble to use.

The specific use mode and function of the embodiment are as follows:

in the invention, the device is arranged at the top of a feed inlet of a grinding device, cereal agricultural products are poured into the material storage assembly 1, the device can start to feed the interior of the grinding device uniformly, stably and continuously by starting a power supply of the driving motor 301, when the driving motor 301 rotates, the driving rod 3021 of the driving turntable 302 can drive the driving push block 401 to reciprocate under the action of the driving groove 4011, the cereal agricultural products at the bottom of the feeding hopper 102 are pushed out of the interior of the feeding hopper 102 for feeding, the driving push block 401 and the driven push block 402 are arranged in the feeding hopper 102, the continuous and uninterrupted feeding operation can be realized under the cooperation effect of the two push blocks, when the driving push block 401 moves, the synchronous rack 4021 of the driving push block 401 can drive the synchronous gear 2022 to rotate, and simultaneously when the synchronous gear 2022 rotates, the driven push block 402 can be driven by the synchronous rack 4021 of the driven push block 402 to realize the movement in the direction opposite to that of the driving push block 401, therefore, the feeding assembly 4 can continuously and uniformly feed the grain agricultural products in the feeding hopper 102 to the inside of the milling device for use, the opening and closing door 501 can be opened when the active push block 401 is pushed outwards under the action of the opening and closing control block 502 and the opening and closing control rod 4013, and is closed when the active push block 401 is retracted, so that the grain agricultural products are prevented from leaking and polluting the working environment, meanwhile, the inside of the feeding hopper 102 can be prevented from leaking through the leakage-proof blocking plate 1022, the leakage-proof blocking plate 1022 can automatically lift along with the movement of the active push block 401 under the action of the leakage-proof jacking spring 10221, the leakage-proof blocking plate 1022 cannot block the movement and feeding operation of the active push block 401, the feeding assembly 4 is opened when pushed outwards, the collision contact rod 4014 positioned at the outermost end of the opening and closing control rod 4013 cannot be bent when moving outwards, so as to push the control contact rod 5023 to drive the opening door 501 to rotate for ninety degrees to open, and the collision feeler lever 4014 that is located and opens and close inner of control lever 4013 this moment can buckle, so open and close inner collision feeler lever 4014 of control lever 4013 can not hinder initiative ejector pad 401's removal, when feed subassembly 4 inwards contracts and resets, open and close inner collision feeler lever 4014 of control lever 4013 and can't buckle, open and close the collision feeler lever 4014 of control lever 4013 outermost end and can buckle, thereby can close opening and closing door 501 through control feeler lever 5023, influence feed or polluted environment in order to avoid the inside cereal agricultural product of feeding hopper 102 to leak.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
