[0041] The utility model generally relates to a rotary reclamation device, which is connected to an external power source such as a tractor when in use, and is used for reclaiming land. The device itself has a rotary tillage unit and a leveling unit. The device is efficient and energy-saving in land reclamation, easy to operate, and can be applied to various soil environments, such as sandy land, black soil, and cultivated land containing more gravel.

[0042] Reference Figure 1-11 In one embodiment of the utility model, the rotary tillage reclamation equipment 1 includes a rotary tillage unit 2, a leveling unit 3, a hydraulic control unit 6 and a height adjustment unit 4. The rotary tillage unit 2 is arranged in front of the leveling unit 3 and is used to perform rotary tillage operations on the soil. The leveling unit 3 is rotatably connected to the rotary tillage unit 2 and is used to level the soil. The hydraulic control unit 6 is arranged between the leveling unit 3 and the rotary tillage unit 2 and is used to control the movement of the leveling unit 3 relative to the rotary tillage unit 2. The height adjustment unit 4 is connected to the leveling unit 3 and is used to adjust the distance between the leveling unit and the ground, thereby adjusting the height difference between the leveling unit and the rotary tillage unit, so as to ensure efficient and high-quality reclamation of land under different soil conditions. Among them, the rotary tillage unit 2 includes a rotary tillage bracket 20, a rotary tillage shaft 21 and multiple groups of rotary tillage blade groups 23 arranged axially along the rotary tillage shaft 21. The rotary tillage shaft 21 is installed on the rotary tillage bracket 20 and each group of rotary tillage blade groups 23 includes multiple rotary tillage blades 22 arranged radially along the rotary tillage shaft. When the rotary tillage shaft 21 rotates, the rotary tillage blades 22 rotate with the rotary tillage shaft and reclaim the land. The rotary tillage and reclamation equipment 1 can be connected to an external power source to provide power to it. For example, the external power source can be a vehicle such as a tractor. The external power source is connected to the front of the rotary tillage unit 2. The external power source pulls the rotary tillage and reclamation equipment 1 to operate on the soil, first performing rotary tillage on the soil and then leveling the soil.

[0043] After careful study of existing reclamation equipment, the inventor found that by adjusting the rotating axis of the rotary tiller, that is, setting the rotary tiller to rotate around the central axis of the rotary tiller shaft 21, the blade breakage rate can be greatly reduced while improving the reclamation efficiency. In addition, by adjusting the distance between the rotary tillage unit and the leveling unit, the land reclamation quality can be greatly improved.

[0044] In addition, the utility model can adjust the height of the leveling unit 3 as needed through the coordinated use of the hydraulic control unit 6 and the height adjustment unit 4, thereby ensuring the leveling effect of the leveling unit and preventing the leveling unit from being stuck.

[0045] In addition, by controlling the leveling unit 3 to rotate relative to the rotary tilling unit 2 through the hydraulic control unit 6, it is also possible to adjust whether the leveling unit 3 is in a working state or a non-working state. Figure 1-11 The state shown is a working state. When the leveling unit 2 is rotated and flipped upward, it enters a non-working state. The rotary tillage device can follow an external power source such as a tractor to transfer the working place.

[0046] In one embodiment of the utility model, the rotary tiller 22 includes a root 221 and a blade 222, one end of the blade 222 away from the root 221 is bent to form an arc, the bending directions of the blades of two adjacent rotary tillers in each set of rotary tillers are opposite, and the blades in two adjacent sets of rotary tillers are staggered. This design can help to better break up the soil, improve the reclamation efficiency and make the soil loose.

[0047] In one embodiment, referring to Figure 3-4 Each rotary tiller blade group 23 contains an even number of rotary tillers 22, the blades 222 of adjacent rotary tillers 22 are in opposite directions, and the blades 222 of opposite rotary tillers 22 are in the same direction.

[0048] Specifically, refer to Figure 3-4 Any rotary tiller blade group 23 is rotated by a certain angle compared with the adjacent rotary tiller blade group 23, that is, the rotary tillers 22 in adjacent rotary tiller blade groups 23 are staggered, and the blades 222 of the rotary tillers 22 in adjacent rotary tiller blade groups 23 are not on the same radial projection of the rotary tiller shaft 21.

[0049] In one embodiment of the present invention, referring to Figure 3-4 A rotary tiller blade disc 24 for mounting a rotary tiller blade group is also provided along the axial direction of the rotary tiller shaft 21, and a rotary tiller blade groove 241 for mounting a rotary tiller blade 22 is provided along the circumferential direction of the rotary tiller blade disc 24. The blade root 221 of the rotary tiller blade 22 is inserted into the rotary tiller blade groove 241 and fixed by screws or the like. The rotary tiller blade disc 24 and the rotary tiller shaft 21 may be connected by a spline sleeve.

[0050] In one embodiment of the present invention, referring to Figure 1 The leveling unit 3 includes a leveling bracket 34 and a leveling shaft 31. The leveling bracket 34 can be rotatably connected to the rotary tillage bracket 20. Both ends of the leveling shaft 31 can be rotatably installed on the leveling bracket 34 and are provided with multiple groups of leveling blade groups 32. Each group of leveling blade groups 32 is arranged around the leveling shaft 31 and includes multiple leveling blades 33. Two adjacent groups of leveling blade groups are arranged at a certain distance.

[0051] Optionally, refer to Figure 1 The leveling blade 33 is V-shaped with the tip facing outward.

[0052] Optionally, the height of the positive blade 33 is smaller than the height of the rotary tillage blade 222 .

[0053] In one embodiment of the present invention, along the axis direction of the leveling shaft 31, any leveling blade set 32 ​​can be rotated by a certain angle compared to the adjacent leveling blade set 32. That is, the leveling blades 33 in the adjacent leveling blade sets 32 are arranged in a staggered manner, and the tips of the leveling blades 33 in the adjacent leveling blade sets 32 are not on the same radial projection of the leveling shaft 31. Figure 1 The leveling blades 33 in adjacent leveling blade groups 32 are not staggered, and the tips of the leveling blades 33 in adjacent leveling blade groups 32 are on the same radial projection of the leveling axis 31 .

[0054] In one embodiment, the hydraulic control unit 6 includes a hydraulic cylinder 61 and a controller (not shown), the two ends of the hydraulic cylinder 61 are respectively fixedly connected to the leveling bracket 34 and the rotary tillage bracket 20, and the controller is connected to the hydraulic cylinder through a hydraulic pipeline. The controller can be set in the cab of an external power source such as a tractor, and the movement of the hydraulic cylinder can be controlled by operating the controller in the cab, thereby controlling the movement of the leveling unit. It can be seen that the leveling bracket 34 can be driven to rotate by the extension and contraction of the hydraulic cylinder, thereby lowering or raising the height of the leveling shaft and the leveling blade group from the ground.

[0055] Optionally, the leveling bracket 34 includes a first end plate 341 and a second end plate 342 located at both ends, a leveling beam 343 connected between the first end plates at both ends, and a leveling baffle 344 connected between the second end plates at both ends, and both ends of the height adjustment unit 4 are respectively connected between the leveling baffle 344 and the leveling beam 343. Optionally, the height adjustment unit 4 includes a mounting seat 43 and a lead screw 41, the mounting seat 43 is integrally extended from the upper part of the leveling baffle 344 and fixedly connected to the housing of the lead screw, the lower end of the lead screw 41 is fixed on the leveling beam 343, and the extension or shortening of the lead screw can be adjusted by the lead screw knob 42, thereby adjusting the height of the leveling beam 343.

[0056] It should be noted that in the present invention, the hydraulic control unit 6 is used to control the overall lifting of the leveling unit, that is, when the hydraulic cylinder of the hydraulic control unit 6 is extended, the entire leveling unit rotates and descends, and the leveling beam 343 also follows the descent, which may cause the height of the leveling beam to be lower than the ground, resulting in soil jamming, causing the leveling shaft to move unsmoothly. At this time, the height of the leveling beam can be raised by the height adjustment unit, thereby ensuring that when the leveling shaft and the leveling blades are lowered, the leveling beam 343 maintains a high position to prevent the occurrence of soil jamming. In other words, the present invention achieves a good technical effect through the coordinated use of the hydraulic control unit and the height adjustment unit, which can reduce the occurrence of faults in actual use, greatly improve the reclamation efficiency, and can be adjusted according to different working environments, expanding the product's scope of use and application scenarios.

[0057] Optionally, the leveling baffle 344 is a hollow structure. The hollow structure design can prevent soil from being integrated on the inner surface of the baffle and affecting the rolling of the leveling shaft 31.

[0058] In one embodiment of the present invention, referring to Figure 1 The rotary tillage support 20 includes rotary tillage end plates 26 at both ends and a first rotary tillage beam 27 and a second rotary tillage beam 28 connected between the rotary tillage end plates 26. The rotary tillage reclamation equipment 1 is also provided with an external connection component 5, which is used to connect an external power source such as a tractor and includes a connection arm 51 respectively connected to the first rotary tillage beam and the second rotary tillage beam.

[0059] Specifically, refer to Figure 1 The external connection component 5 includes four connection arms 51, the lower ends of two of the four connection arms 51 are connected to the second cross beam at intervals, the lower ends of the other two of the four connection arms are connected to the first cross beam at intervals, and the upper ends of the four connection arms are interconnected and fixed to the external power source, thereby connecting the leveling unit and the rotary tillage unit to the external power source.

[0060] Optionally, the rotary tillage unit further includes an upper cover plate 25 , which is openably and closably disposed above the rotary tillage support 20 .

[0061] Specifically, refer to Figure 1 The rotary tillage and reclamation device 1 further includes a drive shaft 6, and the external power source outputs power to the rotary tillage unit 2 through the drive shaft 6. For example, the drive shaft is arranged in a direction perpendicular to the rotary tillage shaft and is connected to the rotary tillage shaft through a reversing gear, so that the external power source provides power to the rotary tillage unit 2 through the drive shaft 6.

[0062] Optionally, refer to Figure 1-3 , the driving shaft 6 is arranged between the connecting arms 51. That is, the connecting arms 51 are arranged around the driving shaft 6 to form a ring-shaped surrounding form.

[0063] In one embodiment of the present invention, the rotary tillage unit 2 further includes a soil retaining plate 29, both ends of which are rotatably connected to the rotary tillage bracket 20, and the soil retaining plate 29 is arranged behind the rotary tillage shaft 21 and the rotary tillage blade 22.
