[0028] See also Figure 1 , Figure 4 , Figure 5An auxiliary unloading mechanism 9 is provided inside the feed box 7, and the auxiliary unloading mechanism 9 includes a protective shell 91. The inner right side wall of the feed box 7 is fixedly connected with the protective shell 91. A rotating shaft 92 is installed inside the protective shell 91 through a bearing.

[0030] The specific implementation process of the utility model is as follows: When in use, as for the process of harvesting and crushing corn stalks, please refer to the self-propelled corn stalk green or yellow silage harvester published in the utility model patent with announcement number CN202979679U for details, which will not be repeated here;

[0031] By pushing the handle 89 to rotate, the screw 88 is driven to rotate. Under the relationship of threaded connection, the slider 1 83 can be driven to slide along the inner wall of the front fixing plate 82 to drive the support shaft 85 to move, and then the slider 2 84 can slide along the inner wall of the rear fixing plate 82 to ensure that the support shaft 85 drives the rice pressing roller 86 to be in a stable moving state. Under the action of the rice pressing roller 86, the corn stalks can be guided for subsequent harvesting and crushing. The setting of a single screw 88 and a handle 89 can ensure the convenience of use and avoid the problem of requiring the cooperation of multiple people.

[0032] By setting the forage box 7, the harvested and crushed corn stalks can be stored and unloaded for use. When there is less tailings left in the forage box 7, the forward and reverse motors 97 are started to rotate forward to drive the gear 98 to rotate. Under the meshing relationship, the gear 98 drives the half gear 95 to rotate, and then drives the impact ball 93 to move to the left, so that the impact ball 93 drives the rubber block 94 to break away from the inner wall of the forage box 7, and when the upper teeth of the half gear 95 contact the limit plate 96, the impact ball 93 no longer moves. When the forward and reverse motors 97 drive the output shaft to drive the gear 98 to rotate, the impact ball 93 will stop moving. When rotating in the reverse direction, similarly, the impact ball 93 drives the rubber block 94 to deflect to the right, and when the lower teeth of the half gear 95 contact the limit plate 96, the impact ball 93 stops moving, and finally the rubber block 94 contacts the inner wall of the feed box 7, continuously impacting and vibrating the feed box 7 to improve the feeding effect of the remaining tailings. Generally speaking, the mechanical force of the forward and reverse motor 97 is the main power source to drive the impact ball 93 to move, and the gravity of the impact ball 93 will have a certain influence on the movement process, playing a role of assisting the fall, so as to ensure the subsequent normal impact use;

[0033] As for the forward and reverse operation of the forward and reverse motor 97, the forward and reverse rotation can be achieved through a controller, and the controller can change the direction of the forward and reverse motor 97 by adjusting the direction and magnitude of the current. This is a mature existing technology.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
