[0025] Example 1 Reference Figure 1 to Figure 6, which is the first embodiment of the present invention, an automatic feeding device for grass silk processing is proposed, including a feeding box 1 and a fixed frame 10, the bottom of the feeding box 1 is fixedly connected with a supporting leg 2, the inner bottom of the feeding box 1 is provided with an opening 3, the inner bottom of the feeding box 1 is provided with a filter screen 4, the inner bottom of the feeding box 1 is fixedly connected with a guide plate 5, the inner side of the fixed frame 10 is fixedly connected with a guide plate 11, the inside of the feeding box 1 is provided with a convenient feeding mechanism 6, the front end of the feeding box 1 is provided with a pushing mechanism 7, and the bottom of the feeding box 1 is provided with a shaking mechanism 8; the convenient feeding mechanism 6 includes a bracket 61, a mounting frame 66 and a connecting frame 68, the bracket 61 penetrates and is rotatably connected with a rotating shaft 62, the surface of the rotating shaft 62 is fixedly connected with an active roller 63, the inner side of the bracket 61 is rotatably connected with a driven roller 64, a conveyor belt 65 is provided between the active roller 63 and the driven roller 64, the mounting frame 66 is fixedly connected to the side of the feeding box 1, the inner side of the mounting frame 66 is fixedly installed with a motor 67, the guide plate 11 The end away from the conveyor belt 65 is inclined, and the output shaft of the motor 67 is fixedly connected to the rotating shaft 62. After the grass falls onto the guide plate 11, it will slide down along the inclined direction of the guide plate 11 due to gravity. When the motor 67 is turned on, its output shaft will drive the rotating shaft 62 to rotate. The connecting frame 68 is fixedly connected to the conveyor belt 65. A torsion spring rod 69 is arranged on the inner side of the connecting frame 68. The surface of the torsion spring rod 69 is fixedly connected to the feeding plate 611. The horizontal distance from the surface of the conveyor belt 65 to the guide plate 11 is greater than the distance from the feeding plate The horizontal length of 611, the loading plate 611 will contact with the guide plate 11 during the process of following the movement of the conveyor belt 65. At this time, the deflection of the torsion spring rod 69 and the loading plate 611 will not affect the movement of the conveyor belt 65. The size of the opening 3 is larger than the size of the loading plate 611. There are two groups of guide plates 5, and the two groups of guide plates 5 are arranged in an eight-shaped shape. The overall larger opening 3 will not affect the movement of the loading plate 611 following the conveyor belt 65. The eight-shaped guide plate 5 plays a role in guiding the forage.

[0026] In this embodiment, when it is necessary to perform feeding work with a height difference, the entire device is moved to a suitable position, the grass is put into the feeding box 1, and the motor 67 is turned on. The motor 67 drives the rotating shaft 62 to rotate through its output shaft, and the rotation of the rotating shaft 62 drives the active roller 63 to rotate. The active roller 63 rotates and cooperates with the driven roller 64 to drive the conveyor belt 65 to move. The movement of the conveyor belt 65 drives the feeding plate 611 to move through the connecting frame 68 and the torsion spring rod 69. The overall large opening 3 will not affect the movement of the feeding plate 611 following the conveyor belt 65. In the process of the feeding plate 611 moving from the bottom to the top, Part of the grass in the feeding box 1 is taken away, and when the loading plate 611 moves to the upper side, it will flip over. At this time, the grass falls onto the guide plate 11 and slides down along the inclined direction of the guide plate 11 due to gravity to complete the loading. When the loading plate 611 continues to move, it will contact the guide plate 11. At this time, the torsion spring rod 69 and the loading plate 611 will be deflected and will not affect the movement of the conveyor belt 65. Then the elastic force of the torsion spring on the torsion spring rod 69 drives the loading plate 611 to be restored. Through the cyclic movement of the array loading plate 611, the grass in the feeding box 1 is loaded in batches. The overall use is more convenient and saves labor.

[0027] Example 2 Reference Figures 1 to 8, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the pushing mechanism 7 includes a hydraulic chamber 71 and a rotating gear 76. The hydraulic chamber 71 penetrates and is fixedly connected to the front end of the charging box 1. The internal piston at one end of the hydraulic chamber 71 is slidably connected to a piston rod A72. The end of the piston rod A72 away from the hydraulic chamber 71 is fixedly connected to a gear rod 73. The internal piston at the other end of the hydraulic chamber 71 is slidably connected to a piston rod B74. The end of the piston rod B74 away from the hydraulic chamber 71 is fixedly connected to a push plate 7. 5. The end of the push plate 75 close to the piston rod B74 is fixedly connected to a return spring 77. The end of the return spring 77 away from the push plate 75 is fixedly connected to the hydraulic chamber 71. The rotating gear 76 is fixedly connected to the surface of the rotating shaft 62. The rotating gear 76 is an incomplete gear, and the teeth on the rotating gear 76 are meshed with the teeth on the gear rod 73 in the initial state. When the rotating gear 76 rotates and its upper teeth are meshed with the teeth on the gear rod 73, the gear rod 73 will be driven to move toward the front end. The push plate 75 is located inside the charging box 1, and the push plate 75 The bottom of the feeding box 1 is close to the inner bottom of the feeding box 1. When the push plate 75 moves to the rear end, the grass in the feeding box 1 will be pushed toward the feeding plate 611. The shaking mechanism 8 includes an extrusion block 81 and a connecting plate 82. The extrusion block 81 is fixedly connected to the conveyor belt 65. The top of the connecting plate 82 is fixedly connected to the bottom of the feeding box 1. The bottom of the connecting plate 82 is fixedly connected to a pneumatic chamber 83. One end of the pneumatic chamber 83 is provided with an air bag 84. The air bag 84 is in an expanded state in the initial state. The top of the air bag 84 is connected to the bottom of the conveyor belt 65. The distance is smaller than the horizontal length of the extrusion block 81. When the extrusion block 81 moves to the bottom following the conveyor belt 65, it will squeeze the airbag 84. The other end of the air pressure chamber 83 is internally piston-slidingly connected with a piston rod C85. The top of the piston rod C85 is fixedly connected with an impact block 86. The top of the impact block 86 is close to the bottom of the filter screen 4 in the initial state, and the impact block 86 is made of rubber. When the impact block 86 moves upward, it will hit the filter screen 4. The impact block 86 made of rubber is elastic and will not cause damage to the filter screen 4.

[0028] Compared with Example 1, further, when the motor 67 is turned on to drive the rotating shaft 62 to rotate, the rotation of the rotating shaft 62 will also drive the rotating gear 76 to rotate. When the rotating gear 76 rotates and its upper teeth mesh with the teeth on the gear rod 73, it will drive the gear rod 73 to move toward the front end. The gear rod 73 moves toward the front end and drives the piston rod A72 to move toward the front end. The movement of the piston rod A72 toward the front end will drive the piston rod B74 to move toward the rear end through the hydraulic pressure in the hydraulic chamber 71. The movement of the piston rod B74 toward the rear end drives the push plate 75 to move toward the rear end, and the reset spring 77 is stretched. When the rotating gear 76 rotates to the toothless part and disengages from the gear rod 73, the reset spring 77 rebounds and drives the push plate 75 and the piston rod B74 to move toward the front end to restore. The hydraulic pressure in the hydraulic chamber 71 drives the piston rod A72 and the gear rod 73 to move toward the rear end to restore, thereby forming a cycle. The push plate 75 is repeatedly moved to the rear end to cooperate with the guide plate 5 to push the hay to the vicinity of the upper feeding plate 611 to cooperate with the feeding work, which effectively prevents the hay from remaining at the bottom of the feeding box 1. When the extrusion block 81 follows the conveyor belt 65 to move to the bottom, it will squeeze the air bag 84. The air pressure inside the air bag 84 will enter the air pressure chamber 83 to push the piston rod C85 to move upward. The upward movement of the piston rod C85 will drive the impact block 86 to move upward and hit the filter 4. When the extrusion block 81 leaves the air bag 84, the air bag 84 rebounds, and the air pressure returns to the air pressure chamber 83. The piston rod C85 moves downward and drives the impact block 86 to restore. The impact block 86 repeatedly moves upward to hit the filter 4, causing the filter 4 to vibrate slightly. The shaking of the filter 4 can screen the hay in the feeding box 1 to prevent stones and the like from being mixed in the hay.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
