AI Technical Summary
During the cutting process, existing silage cutters suffer from changes in the distance between the fixed and moving blades due to blade wear and grinding by the whetstone, which affects the quality of silage and lacks effective automatic adjustment methods.
An automatic blade setting mechanism for silage harvester cutting was designed. It utilizes a ball joint structure, rocker arm, lead screw, and knock sensor. The motor controls the lead screw to drive the rocker arm to adjust the position of the fixed blade, and the knock sensor provides feedback signals to achieve precise blade setting.
It achieves precise control over the cutting process, ensuring the quality of the cutting, improving the working efficiency of the silage machine and the quality of the feed, and reducing manual intervention.

Description
TECHNICAL FIELD
[0001] The utility model relates to a silage machine sectioning automatic tool setting mechanism. BACKGROUND
[0002] With the attention of the state to the animal husbandry, the overall national meat and milk intake is improved. The quality and delicacy of the animal husbandry feed are required higher and higher, at present, most of the green forage harvester (silage machine) is imported from abroad, and in the increasingly complex foreign situation, it is necessary to cultivate independent mechanized harvesting, and the localization of silage machine is more and more important.
[0003] The sectioning of green forage directly affects the quality of feed, and the real-time state of the cutter is an important means to ensure the harvesting efficiency, and in addition to the sharp moving cutter, the sectioning distance between the moving cutter and the fixed cutter also affects the quality of the sectioned material. The two are closely related. In the harvesting of the silage machine, with the wear of the sectioning cutter itself and the grinding of the grinding stone, the length gradually becomes shorter. At this time, the distance and parallelism between the corresponding sectioning fixed cutter and the moving cutter also change, which affects the sectioning effect of the silage feed. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at solving the above technical deficiencies, and provides a silage machine sectioning automatic tool setting mechanism.
[0005] A silage machine sectioning automatic tool setting mechanism, comprising a rack, a moving cutter and a fixed cutter, the moving cutter is rotationally connected to the rack, one end of the fixed cutter is hinged to the rack, and the other end is connected to a push-pull mechanism, and the push-pull mechanism is used for controlling the fixed cutter to approach or move away from the moving cutter.
[0006] Further, the hinged structure of one end of the fixed cutter and the rack is a spherical hinge, a hinged seat is arranged on the rack, an arc-shaped groove is arranged on the surface of the hinged seat, one end of the fixed cutter is provided with a spherical connector, and the connector is rotationally connected in the arc-shaped groove.
[0007] Further, the push-pull mechanism comprises a rocker arm and a lead screw, one end of the lead screw is hingedly connected to the rack through a rotating shaft, the other end of the lead screw is connected to a connecting seat, the connecting seat is hingedly connected to one end of the rocker arm, and the other end of the rocker arm is connected to the fixed cutter.
[0008] Further, the connecting seat is threadedly connected with the lead screw.

[0016] In order to deepen the understanding of the utility model, the utility model will be further described below in conjunction with examples and drawings, and the examples are only used to explain the utility model and do not constitute the limitation to the protection scope of the utility model.
[0017] As shown in Figs. 1-2 The shaft 1, the lead screw 2, the connecting seat 3, the rocker arm 4, the limiting column 5, the fixed cutter 6, the shock sensor 7, the hinged seat 8 and the moving cutter 9;
[0018] A kind of silage machine cutting section automatic tool setting mechanism, including rack, moving cutter 9, fixed cutter 6, the moving cutter 9 is rotatably connected on rack, the fixed cutter 6 is hinged with one end of rack, the other end is connected with push-pull mechanism, the push-pull mechanism is used to control fixed cutter 6 close to or away from moving cutter 9.
[0019] In the present example, the hinged structure of the one end of fixed cutter 6 and rack is spherical hinge, the rack is provided with hinged seat 8, the surface of hinged seat 8 is provided with arc-shaped recess, the one end of fixed cutter 6 is provided with spherical connector, and connector is rotatably connected in arc-shaped recess.
[0020] In the present example, the push-pull mechanism includes rocker arm 4 and lead screw 2, one end of lead screw 2 is hinged on rack through shaft 1, the other end of lead screw 2 is connected with connecting seat 3, connecting seat 3 is hinged with one end of rocker arm 4, and the other end of rocker arm 4 is connected with fixed cutter 6.
[0021] In the present embodiment, the connecting seat 3 is threadedly connected with the screw rod 2.
[0022] In the present embodiment, the rocker arm 4 is connected with the fixed blade 6 by means of bolts.
[0023] In the present embodiment, the fixed blade 6 is provided with knock sensors 7 on both sides.
[0024] In the present embodiment, the rack is provided with a limiting column 5, and the surface of the rocker arm 4 is provided with a limiting hole, the diameter of the limiting hole being greater than the diameter of the limiting column 5, and the limiting column 5 is located in the limiting hole.
[0025] Working principle: when the relative position of the fixed blade 6 and the moving blade 9 needs to be adjusted, the rocker arm 4 is driven to move by the screw rod 2, so that the fixed blade 6 connected with the rocker arm 4 approaches or moves away from the moving blade 9. In actual work, since the length of the fixed blade 6 is relatively large, the same push-pull mechanism is arranged on both sides of the fixed blade 6. Before work, the fixed blade 6 needs to be leveled, and the two push-pull structures are started in sequence, so that both sides of the fixed blade 6 are in contact with the moving blade 9. When colliding, vibration will be generated, the knock sensor 7 senses the vibration and feeds back the signal to the control console, and the control console sends a stop signal to stop the motor from working. If manual adjustment is needed, personnel need to judge by the collision sound.
[0026] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
