When branches and debris are stuck between the rake teeth on the adjacent first mounting ring and the second mounting ring, as the rake teeth on the second mounting ring continue to rotate, the stuck branches and debris can be more easily dropped from between the two, thereby ensuring the plowing efficiency and plowing effect of the rake teeth;

[0016] 3. The present invention is provided with a cutting blade. When branches and debris on the ground are turned upward with the rake teeth and contact the rotating cutting blade, the cutting blade can cut the branches and debris, so that the branches and debris can be more easily separated from the rake teeth on the adjacent first mounting ring and the second mounting ring, thereby ensuring the normal operation of the rake teeth and the tillage efficiency and tillage effect of the soil by the rake teeth;

A reset assembly 9 is provided between the second fixing ring 8 and the second mounting ring 5. A plurality of rake teeth 10 are fixedly connected to the peripheries of the first mounting ring 4 and the second mounting ring 5. A plurality of first bevel gears 11 are fixedly sleeved on the rotating shaft 3, and the plurality of first bevel gears 11 are distributed one by one between two adjacent first mounting rings 4 and the second mounting rings 5, wherein a driving assembly 12 is provided on the first bevel gear 11 located in the middle of the rotating shaft 3, and a transmission assembly 13 is provided on the remaining first bevel gears 11. The rake teeth 10 are spiral in shape as a whole, and the plurality of rake teeth 10 on the same first mounting ring 4 and the same second mounting ring 5 are rotationally symmetrical about the rotating shaft 3;

[0029] The driving assembly 12 includes a first connecting sleeve 121, which is rotatably sleeved on the rotating shaft 3, and the first bevel gear 11 located in the middle of the rotating shaft 3 is located inside the first connecting sleeve 121, and the top of the first connecting sleeve 121 is vertically rotated and inserted with a driving shaft 122, and the top of the driving shaft 122 is rotated and inserted into the top of the protective cover 1, and both ends of the driving shaft 122 are fixedly sleeved with second bevel gears 123, and the second bevel gear 123 at the bottom of the driving shaft 122 is connected to the first connecting sleeve The first bevel gear 11 in the 121 is meshed, and a mounting tube 124 is horizontally arranged at the top of the driving shaft 122, and the mounting tube 124 is fixedly connected to the top of the protective cover 1, and the top of the driving shaft 122 is rotatably inserted into the mounting tube 124, and the front end of the mounting tube 124 is rotatably inserted with a connecting shaft 125, and the part of the connecting shaft 125 located in the mounting tube 124 is fixedly sleeved with a third bevel gear 126, and the third bevel gear 126 is meshed with the second bevel gear 123 at the top of the driving shaft 122;

[0030] Before use, the protective cover 1 is first connected to the tractor through the mounting frame 2, and then the connecting shaft 125 is connected to the driving machine of the tractor. When in use, when the power of the driving machine is transmitted to the connecting shaft 125, the connecting shaft 125 can drive the driving shaft 122 to rotate through the transmission effect of the third bevel gear 126 on the second bevel gear 123. As the driving shaft 122 rotates, the driving shaft 122 can drive the rotating shaft 3 to rotate through the transmission effect of the second bevel gear 123 on the first bevel gear 11, thereby realizing the rotation operation of the rake teeth 10.

[0031] During use, when the rake teeth 10 on the first mounting ring 4 come into contact with the ground, since the rake teeth 10 are spiral, as the rake teeth 10 come into contact with the ground, the ground can apply a thrust to the first mounting ring 4 in a direction close to the first fixing ring 6 through the rake teeth 10, so that the first mounting ring 4 can drive the rake teeth 10 connected thereto to move horizontally, and as the first mounting ring 4 moves, the first return spring 7 can be compressed, and since the rake teeth 10 are subjected to different thrusts from the soil in the horizontal direction when they are in contact with the soil at different positions, the first mounting ring 4 can be driven to move horizontally. The amount by which the return spring 7 is compressed is also different, and thus during the entire plowing process, the distance between the rake teeth 10 located on the adjacent first mounting ring 4 and the second mounting ring 5 can be continuously changed. Thus, during the process of the rake teeth 10 plowing the land, when branches or debris are stuck between the rake teeth 10 on the adjacent first mounting ring 4 and the second mounting ring 5, the stuck branches or debris can be more easily removed from between the two as the rake teeth 10 on the first mounting ring 4 continue to move, thereby preventing the rake teeth 10 from being stuck by branches or debris, thereby affecting the plowing efficiency and plowing effect of the rake teeth 10.

[0032] like Figures 4 to 6 As shown, the reset assembly 9 includes two arc-shaped first extrusion blocks 91 and two arc-shaped second extrusion blocks 92, and the two first extrusion blocks 91 and the two second extrusion blocks 92 are alternately distributed, the two first extrusion blocks 91 are fixedly connected to the second fixing ring 8, the two second extrusion blocks 92 are fixedly connected to the second mounting ring 5, and arc-shaped limiting rods 93 are fixedly connected between the two sides of the two second extrusion blocks 92, and the center of the limiting rod 93, the first extrusion block 91, the second extrusion block 92 and the second mounting ring 5 are the same, the two first extrusion blocks 91 are respectively slidably sleeved on the two limiting rods 93, and a second reset spring 94 is fixedly connected between one side of the second extrusion block 92 and the corresponding first extrusion block 91, the second reset spring 94 is sleeved on the corresponding limiting rod 93, and the two second reset springs 94 are rotationally symmetrical about the rotating shaft 3;

[0033] By providing the reset assembly 9, when the rake teeth 10 on the second mounting ring 5 turn the ground, as the rake teeth 10 on the second mounting ring 5 contact the ground, the rake teeth 10 can drive the second mounting ring 5 to rotate at a certain angle, and as the second mounting ring 5 rotates, the second extrusion block 92 can cooperate with the corresponding first extrusion block 91 to squeeze the second reset spring 94, and because the rake teeth 10 when contacting soils of different hardness, the reaction size of the soil on the rake teeth 10 is also different, so that the rotation angle of the second mounting ring 5 is also different, and then when the rake teeth 10 on the second mounting ring 5 turn the land, the rake teeth 10 on the second mounting ring 5 can be dynamically displaced at a certain angle with the rake teeth 10 on the adjacent first mounting ring 4, so that when branches and debris are stuck between the rake teeth 10 on the adjacent first mounting ring 4 and the second mounting ring 5, as the rake teeth 10 on the second mounting ring 5 continue to rotate, the stuck branches and debris can be more easily dropped from between the two, thereby ensuring the turning efficiency and turning effect of the rake teeth 10.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 8 As shown, the transmission assembly 13 includes a second connecting sleeve 131, which is rotatably sleeved on the rotating shaft 3, and all the first bevel gears 11 except those located in the middle of the rotating shaft 3 are distributed in a plurality of second connecting sleeves 131 in a one-to-one correspondence, and a transmission shaft 132 is inserted and penetrated through the top of the second connecting sleeve 131 for vertical rotation, and the top of the transmission shaft 132 is vertically rotatably connected to the inner wall of the top of the protective cover 1, and a fourth bevel gear 133 is fixedly sleeved on the bottom end of the transmission shaft 132, and the fourth bevel gear 133 is meshed with the first bevel gear 11 in the second connecting sleeve 131, and a sleeve 134 is detachably fixedly sleeved on the part of the transmission shaft 132 located outside the second connecting sleeve 131, and a plurality of vertical cutting edges 135 are evenly distributed on the surface of the sleeve 134, and the cutting edges 135 are fixedly connected to the surface of the sleeve 134;

[0035] The cutting blade 135 is located at the lower half of the sleeve 134, and the top of the cutting blade 135 is higher than the height of the top of the rake teeth 10 when it is facing upward. The upper half of the sleeve 134 is annularly distributed with upper and lower groups of knocking rods 14, and the number of knocking rods 14 in each group is multiple. The knocking rods 14 are vertically fixedly connected to the surface of the sleeve 134, and the multiple knocking rods 14 in the two groups are alternately distributed;

[0036] By providing the cutting blades 135, during the process of the rake teeth 10 plowing the land, as the rotating shaft 3 rotates, the multiple first bevel gears 11 can drive the transmission shaft 132 to rotate through the multiple fourth bevel gears 133, and as the transmission shaft 132 rotates, the cutting blades 135 on the sleeve 134 can rotate together with the driving shaft 122, so that when the branches and debris on the ground are flipped upward with the rake teeth 10 and contact the rotating cutting blades 135, the cutting blades 135 can cut the branches and debris, so that the branches and debris can be more easily separated from the rake teeth 10 on the adjacent first mounting rings 4 and second mounting rings 5, thereby ensuring the normal operation of the rake teeth and ensuring the plowing efficiency and plowing effect of the rake teeth 10 on the soil.

[0037] By providing a knocking rod 14, the knocking rod 14 can rotate together with the sleeve 134 as the sleeve 134 rotates. During this process, when a larger mud block comes into contact with the knocking rod 14 driven by the rake teeth 10, the two groups of knocking rods 14 distributed up and down can knock the mud block, so that the mud block can be split into smaller mud blocks under the hitting of the knocking rods 14, thereby cooperating with the rake teeth 10 to improve the tillage effect of the soil.

[0038] like Figure 1 and Figure 2 As shown, the first mounting ring 4 and the second mounting ring 5 are fixedly connected with a protective sleeve 15 on one side close to the first fixing ring 6 and the second fixing ring 8, and the first fixing ring 6, the first return spring 7, the second fixing ring 8 and the return assembly 9 are always located inside the protective sleeve 15;

[0039] By providing the protective cover 15, during the process of the rake teeth 10 plowing the land, the protective cover 15 can protect the first fixed ring 6, the first return spring 7, the second fixed ring 8 and the return assembly 9, thereby preventing soil from falling into the first return spring 7 and the return assembly 9, and ensuring the normal operation of the first return spring 7 and the return assembly 9.

[0040] like Figure 1 and Figure 2 As shown, the driving shaft 122 and the transmission shaft 132 are both fixedly sleeved with the protective cover 16 near the bottom end, and the protective cover 16 is rotatably sleeved at the connection between the first connecting sleeve 121 and the second connecting sleeve 131 and the driving shaft 122 and the transmission shaft 132;

[0041] By providing the protective cover 16, during the process of the rake teeth 10 plowing the land, the protective cover 16 can protect the top of the connection between the first connecting sleeve 121 and the second connecting sleeve 131 and the drive shaft 122 and the transmission shaft 132, thereby preventing the turned-up soil from getting stuck in the above-mentioned connection, thereby ensuring the normal rotation of the drive shaft 122 and the transmission shaft 132.

[0042] like Figure 1 and Figure 2 As shown, both sides of the protective cover 1 are rotatably connected with a swivel 17, and a vertical U-shaped bracket 18 is fixed on the side of the swivel 17 away from the protective cover 1, and when the U-shaped bracket 18 is opened upward, the bottom of the U-shaped bracket 18 is lower than the bottom end of the bottom rake teeth 10;

[0043] By providing the U-shaped bracket 18, when the use is finished, as the protective cover 1 is placed on the ground, the two U-shaped brackets 18 can be supported on both sides of the protective cover 1, so that the rake teeth 10 can be separated from the ground, and then when the rake teeth 10 are cleaned, all the rake teeth 10 can be driven to rotate by rotating the rotating shaft 3, so that the rake teeth 10 close to the rear side of the protective cover 1 can be rotated to the front side for cleaning, thereby improving the cleaning efficiency of the rake teeth 10;

[0044] When in use, the protective cover 1 can be placed on the ground under the support of the U-shaped bracket 18. When the traction device moves forward, the bottom of the U-shaped bracket 18 can deflect backward under the action of the friction force of the ground. As the U-shaped bracket 18 deflects backward, the protective cover 1 can drive the rake teeth 10 to move downward under the action of gravity and automatically contact the ground. During the plowing process, the two U-shaped brackets 18 can slide along the ground in an inclined state, thereby not affecting the entire plowing operation.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
