The silage feed harvesters in the prior art generally include self-propelled mobile equipment, harvesting equipment, crushing equipment, storage boxes and other equipment. The harvesting equipment, crushing equipment and storage boxes are driven by the self-propelled mobile equipment to move in the field, the silage raw materials are harvested and transported by the harvesting equipment, the silage raw materials are transported to the crushing equipment for crushing, and then the crushed silage raw materials are further transported and transported to the storage box. Finally, when too much crushed silage raw materials are collected in the storage box, the silage raw materials are discharged as a whole onto a special transport vehicle, thereby completing the harvesting operation of the silage raw materials.

[0003] In the prior art, in order to facilitate the discharge of the silage materials in the storage box, a lifting mechanism is usually provided between the storage box and the self-propelled moving device during installation.

The electromagnetic sliding seat 18 is an electromagnetic device well known to those skilled in the art. The electromagnetic sliding seat 18 is powered to generate magnetic force, and the magnetic body 17 is made of ferrous material, so that the magnetic body 17 can be stably magnetically connected to the electromagnetic sliding seat 18.

[0045] A material box fixing assembly 300 is arranged between the mounting frame 1 and the material storage box 4. The material box fixing assembly 300 includes a support seat 20, a lifting screw 22, a first drive motor 23 and a sliding plate 24. There are multiple support seats 20, and the multiple support seats 20 are fixedly connected by a connecting piece 21. The multiple support seats 20 are all located at the bottom of the material storage box 4. The lifting screw 22 is rotatably connected to the mounting frame 1, and the lifting screw 22 is threadedly connected to the connecting piece 21. The first drive motor 23 is arranged in the mounting frame 1. The output end of the motor 23 is fixedly connected to the lifting screw 22, and a sliding plate 24 is slidably connected to the support seat 20, and the sliding plate 24 is fixedly connected to the mounting frame 1. During the lifting and moving process of the material storage box 4, after pausing the movement of the material storage box 4, the first drive motor 23 is started to drive the lifting screw 22 to rotate, so that the lifting screw 22 drives the connecting piece 21 and multiple support seats 20 to rise and fall between the multiple sliding plates 24, so that the support seat 20 supports the bottom of the material storage box 4, so that the material storage box 4 remains stable during the discharge process.

[0046] In this embodiment, it also includes a support frame 25, which is fixedly connected to the top of the storage box 4. The top of the support frame 25 is connected to the feed pipe. In order to avoid affecting the position of the feed pipe during the rising process of the storage box 4, the feed pipe includes a tube body 36, one end of the tube body 36 is connected to the crushing equipment 45, and the other end of the tube body 36 is connected to the feed terminal 38 through a hose 37. The top of the support frame 25 is fixedly connected to the feed terminal 38. During the rising process of the storage box 4, the support frame 25 drives the feed terminal 38 to rise. When the storage box 4 is moved back into the installation frame 1, the feed terminal 38 is reset during the descending process of the support frame 25, so as to avoid affecting the feed terminal 38 during the position adjustment of the storage box 4.

[0047] In the present embodiment, after the silage raw materials are harvested, they need to be sealed and fermented to make silage feed, so during the discharge process of the silage raw materials in the storage box 4, the silage raw materials need to be discharged in multiple groups in a dispersed manner, while the conveying direction of the raw material conveyor belt 30 remains consistent. Therefore, the present application also includes a sliding frame 39, and the sliding frame 39 is fixedly connected to the side of the rotating frame 6 close to the storage box 4, and a sliding member 40 is slidably connected in the sliding frame 39, and a limiting slide 41 is rotatably connected to the side of the sliding member 40 close to the raw material conveyor belt 30 through a rotating shaft, and a guide plate 42 is slidably connected in the limiting slide 41, and a threaded rod 43 is fixedly connected to the sliding member 40, and a nut 44 is threadedly connected to the threaded rod 43. When the silage raw material is moving on the raw material conveyor belt 30, the guide plate 42 is driven to move, and one end of the guide plate 42 is in contact with the raw material conveyor belt 30. Because the sliding member 40 and the limiting slide groove 41 are rotatably connected by a rotating shaft, the angles of the limiting slide groove 41 and the guide plate 42 can be adjusted. By driving the sliding member 40 to slide on the sliding frame 39, the positions of the sliding member 40, the limiting slide groove 41 and the guide plate 42 can also be adjusted. Therefore, with the cooperation of the two guide plates 42 on both sides, the two guide plates 42 are adjusted and overlapped at appropriate angles, so that the silage raw materials can be discharged from both sides of the raw material conveyor belt 30 during the movement of the silage raw materials on the raw material conveyor belt 30, thereby improving the diversity of transportation and discharge of the silage raw materials.

[0048] The working principle of the storage box lifting mechanism for the silage harvester is as follows: a large amount of crushed silage materials are stored in the storage box 4. When the silage materials need to be discharged from the storage box 4, the double-headed electric cylinder 14 is started to move the rotating rings 13 on both sides, so that the rotating rings 13 drive the fixed rings 11 to slide on the rotating shaft 8, so that the meshing rods 12 on the fixed rings 11 are meshed with the corresponding rotating seats 9 through the meshing holes, so that during the rotation of the rotating shaft 8, the fixed rings 11 and the corresponding rotating seats 9 are driven to rotate with the rotating shaft 8, while the rotating seats 9 that are not meshed with the fixed rings 11 will not rotate with the rotating shaft 8, thereby realizing the sequential adjustment of the positions of the rotating frame 6 and the storage box 4. After the rotating frame 6 moves to the specified position, the electromagnetic slide The movable seat 18 is powered to generate magnetic force on the electromagnetic sliding seat 18, and the electromagnetic sliding seat 18 is magnetically connected to the magnetic body 17 on the sliding ring 16, so that the rotating frame 6 remains fixed after moving to the specified position. During the lifting and moving process of the storage box 4, after pausing the movement of the storage box 4, the first driving motor 23 is started to drive the lifting screw 22 to rotate, so that the lifting screw 22 drives the connecting piece 21 and multiple support seats 20 to rise and fall between the multiple sliding plates 24, so that the support seat 20 supports the bottom of the storage box 4, so that the storage box 4 remains stable during the discharging process, and the silage raw materials in the storage box 4 are discharged through the tilted discharge hopper 7, so that the silage raw materials fall onto the raw material conveyor belt 30, and the silage raw materials are unloaded through the raw material conveyor belt 30.
