Specifically, each side wall of the rotating shaft 9 is provided with four limiting grooves 11.

Specifically, each rake disc assembly 5 comprises an inner ring 51, four limiting fixture blocks 52, four return springs 53, four spring columns 54, a rake disc 55, a U-shaped fixture block 56, an outer ring 57 and a scraper 58, the rake disc 55 is fixedly arranged on the rotating shaft 9, the inner ring 51 is rotatably arranged on the side wall of the rake disc 55, the outer ring 57 is rotatably arranged on the side wall of the rake disc 55, one end of the scraper 58 is fixedly arranged on the side wall of the outer ring 57, the other end of the scraper 58 is fixedly connected with the bottom of the corresponding connecting rod 4, the four spring columns 54 are inserted into the inner ring 51 in a circular array, the four limiting fixture blocks 52 are correspondingly arranged at the end portions of the four spring columns 54, the four U-shaped fixture blocks 56 are respectively arranged at the other ends of the four spring columns 54, and the four return springs 53 are respectively sleeved on the outer side walls of the corresponding spring columns 54. Damage or eccentricity through the round rake disc 55, thereby the round rake disc 55 collides with corresponding outer ring 57 when the rotary shaft 9 drives the round rake disc 55 to rotate, make the outer ring 57 incline, the outer ring 57 extrudes the U-shaped fixture block 56, make the U-shaped fixture block 56 break, at this moment, the reset spring 53 lacks the limiting action of the U-shaped fixture block 56 and drives the spring column 54 and the limiting fixture block 52 to move towards the rotary shaft 9 direction, until the limiting fixture block 52 collides with the side wall of the rotary shaft 9, and because of the arrangement of the limiting groove 11 of the side wall of the rotary shaft 9, the limiting fixture block 52 cooperates with the limiting groove 11 to forcibly stop rotating the rotary shaft 9, the worker is reminded to timely replace the round rake disc 55, and the round rake disc 55 around being prevented from being damaged from influencing the inestimable loss caused by the round rake disc 55 around.

Specifically, the adjusting mechanism 3 includes a hinge seat 31, a hydraulic push rod 32, two connecting members 33, a hinge shaft 34 and a hinge member 35, the hinge member 35 is disposed at inner ends of the two connecting rods 4, the hinge seat 31 is disposed at a top of the hinge member 35, one end of the hydraulic push rod 32 is hinged to the hinge seat 31, the hinge shaft 34 is disposed at an end of an output shaft of the hydraulic push rod 32, one ends of the two connecting members 33 are fixedly connected to inner side walls of the two sub-rods 2, and the other ends of the two connecting members 33 are rotatably connected to two ends of the hinge shaft 34. The output shaft of the hydraulic push rod 32 stretches out to drive the hinged seat 31 to move, so that the hinged seat 31 moves, the angle adjustment of the rotating shaft 9 is realized, and the deflection angle of the circular rake disc 55 can be correspondingly adjusted.

Specifically, the thickness of each limiting fixture block 52 is smaller than the width of the limiting groove 11.

Specifically, each U-shaped latch 56 is made of a breakable hard plastic material.

The working principle is that the whole rake disc set is firstly installed on a corresponding agricultural machine, then the output shaft of the hydraulic push rod 32 stretches out to drive the hinged seat 31 to move, so that the hinged seat 31 moves, the angle adjustment of the rotating shaft 9 is realized, the deflection angle of the rake disc 55 is correspondingly adjusted, the machine can be started after the adjustment is finished, the machine drives the rotating shaft 9 to rotate, the rotating shaft 9 rotates to drive all the rake discs 55 to rotate, when soil preparation is carried out, if any one of the rake discs 55 is damaged or eccentric, the rake disc 55 abuts against the corresponding outer ring 57 while the rotating shaft 9 drives the rake discs 55 to rotate, the outer ring 57 tilts, the outer ring 57 presses the U-shaped fixture block 56, so that the U-shaped fixture block 56 is broken, at the moment, the reset spring 53 drives the spring column 54 and the limiting fixture block 52 to move towards the rotating shaft 9 direction under the limiting effect that the U-shaped fixture block 56 lacks the limiting effect, until the limiting fixture block 52 abuts against the side wall of the rotating shaft 9, and due to the arrangement of the limiting groove 11 on the side wall of the rotating shaft 9, the limiting fixture block 52 is matched with the limiting groove 11, so that the rake disc 55 is not damaged and the rake shaft can stop rotating loss caused by the rake shaft.
