Specifically, the first shaft sleeve 51 rotates synchronously with the transmission shaft 2, when the first shaft sleeve 51 is in a rotating state, whether the hinge clamping piece 54 is unfolded to the outside of the first shaft sleeve 51 determines whether the shaft transmission assembly 5 is in transmission connection with the protection mechanism 6, and as can be seen from the above, when the shaft transmission assembly 5 is in transmission connection with the protection mechanism 6, the shaft transmission assembly 5 can apply the rotating force of the transmission shaft 2 to the protection mechanism 6 so as to enable the protection mechanism 6 to be unfolded automatically, and when the protection mechanism 6 is unfolded completely, the shaft transmission assembly 5 can be controlled to be in no transmission connection with the protection mechanism 6 any more so that the protection mechanism 6 is not unfolded any more.

Specifically, since the first cylinder 7 is fixed on the outside of the transmission case 4, and the first shaft housing 51 rotates synchronously with the transmission shaft 2 in most cases, the link assembly 53 can rotate with low friction as the link assembly 53 between the first cylinder 7 and the first shaft housing 51, the link assembly 53 is connected with the telescopic shaft of the first cylinder 7 through the threaded hole 534 on the third shaft housing 533, the second link 531 is rotatably connected with the hinge clip 54 and can slide and stretch in the through hole 512, and the third shaft housing 533 is sleeved on the second link 531 to perform limited sleeving through the annular groove 532, so that the first shaft housing 51 does not affect the rotation when the first cylinder 7 stretches and stretches together with the third shaft housing 533.
The protection mechanism 6 comprises an arc-shaped track 61, an internal tooth shaft sleeve 62, a sliding seat 63 and a folding assembly 64;
the arc-shaped track 61 is embedded on the side surface of the transmission case 4, the inner tooth shaft sleeve 62 is sleeved on the outer side of the first shaft sleeve 51 of the corresponding shaft transmission assembly 5, the sliding seat 63 is slidably connected inside the arc-shaped track 61 and is connected with the inner tooth shaft sleeve 62, and the folding assembly 64 is distributed on the side surface of the transmission shaft 2 and is connected with the sliding seat 63;

Specifically, the inner gear sleeve 62 is movably sleeved on the outer side of the first shaft sleeve 51 and is connected with the sliding seat 63 slidingly connected in the arc-shaped track 61, so that when the inner gear sleeve 62 is in transmission connection with the first shaft sleeve 51, the rotating inner gear sleeve 62 can slide upwards in the arc-shaped track 61 together with the sliding seat 63, and in the process of sliding upwards the sliding seat 63, the folding assembly 64 connected with the sliding seat 63 can be gradually unfolded from a folding state, and the folding assembly 64 can be an existing device such as a folding plate, folding cloth and the like, so long as the existing device can be automatically unfolded when the local upward pulling force is applied to the device, and can be automatically retracted to an initial folding state when the device is reset.
In addition, the invention realizes the control of the unfolding degree of the protection mechanism 6 by arranging the control mechanism 8, and the protection mechanism 6 is reset to an initial state of no shielding the feed inlet above the crushing equipment after being unfolded.

when the sliding seat 63 slides unidirectionally in the arc-shaped track 61, the unidirectional ratchet 812 is separated from the ratchet groove 811, the sliding seat 63 slides unidirectionally in the arc-shaped track 61 to any position, the unidirectional ratchet 812 and the ratchet groove 811 can be reversely clamped, the telescopic end of the second cylinder 83 retracts together with the arc-shaped strip 81 far away from the sliding seat 63 to release the clamping of the unidirectional ratchet 812 and the ratchet groove 811, and meanwhile the sliding seat 63 slides naturally downwards in the arc-shaped track 61.
Specifically, by arranging the movable arc-shaped bar 81 at the outer edge of the arc-shaped rail 61, when the arc-shaped bar 81 is in the initial state, the sliding seat 63 can be located at any position in the arc-shaped rail 61 and can be clamped with the ratchet groove 811 at the inner side of the arc-shaped bar 81 through the installed unidirectional ratchet 812, so that in the sliding process of the sliding seat 63, if the shaft transmission assembly 5 is not transmitted with the protection mechanism 6 any more, the sliding seat 63 can be clamped with the arc-shaped bar 81 at the moment and cannot descend, and the unfolded folding assembly 64 cannot fall back.
When the folding assembly 64 needs to fall back, the telescopic end of the second air cylinder 83 needs to be controlled to retract, and the second air cylinder is rotated along the rotating shaft 82 together with the arc-shaped bar 81, at this time, most of the area of the arc-shaped bar 81 is far away from the arc-shaped rail 61, so that the unidirectional ratchet 812 on the sliding seat 63 is not clamped with the ratchet slot 811 on the inner side of the arc-shaped bar 81 any more, and the sliding seat 63 is caused to naturally slide down to the bottom end of the arc-shaped rail 61 to be clamped with the ratchet slot 811 on the inner side of the arc-shaped bar 81 again.
