When feeding livestock herbivores, forage needs to be crushed by a crushing device to make it easier for herbivores to eat.

[0003] Based on the above, the inventors found that the existing grass crushing device has the following shortcomings:

[0004] 1. The feed inlet is normally open, which causes the crushed dust of the grass to easily float out from the feed inlet, affecting the crushing site environment. It is not convenient to install a self-closing sealing measure on the feed inlet to seal the feed inlet after the grass enters to prevent dust;

[0005] 2. There is no auxiliary support measure on one side of the forage discharge port, which may cause the crushing device to tip over due to the deviation of the center of gravity. It is not convenient to install auxiliary support measures on the crushing device to prevent the crushing device from tipping over due to the deviation of the center of gravity.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In the utility model, Figure 1 As shown, the crusher body 1 is in a placed state, the auxiliary support rod 6 and the placement support rod 8 are both lowered to the limit position, and the bottom end surface of the placement contact plate 9 is in contact with the ground, thereby achieving the placement support of the crusher body 1 to prevent the crusher body 1 from tipping over due to the deviation of the center of gravity. At the same time, the feed closing plate 3 is in a closed state under the action of its own weight. When in use, the feed closing plate 3 is pushed to the right by the grass material, so that the feed closing plate 3 can be flipped open, and the state is as shown in FIG. Figure 4 As shown, after the grass passes through, the feed closing plate 3 will fall back under its own weight to close the feed opening of the grinder housing 2, thereby preventing the grass crushing dust from floating out. At the same time, the flip opening limit position of the feed closing plate 3 can be adjusted by the lifting limit rod 4. When the lifting limit rod 4 rises through the threaded engagement, the flip opening opening of the feed closing plate 3 becomes larger. When the lifting limit rod 4 falls through the threaded engagement, the flip opening opening of the feed closing plate 3 becomes smaller. Figure 1As shown, when the pulverizer body 1 is dragged and moved, the auxiliary support rod 6 is rotated by a tool to engage with the auxiliary support plate 5, so that the auxiliary support rod 6 rises through the threaded engagement, and the placement contact plate 9 is driven by the auxiliary support rod 6 to rise synchronously off the ground, and the placement support rod 8 is rotated by a tool to engage with the dragging bearing frame 7, so that the placement support rod 8 rises through the threaded engagement, and the placement support rod 8 drives the placement contact plate 9 to rise synchronously off the ground.
