Description

TECHNICAL FIELD

[0001] The utility model belongs to soil pulverization rotary tillage technical field especially relates to a soil high pulverization rotary tillage device. BACKGROUND

[0002] Rotary tillage is a kind of mode of soil loosening, pulverization, and currently rotary tillage is carried out by rotary tillage machine, and soil loosening, pulverization are realized by the rotary tillage effect of rotary tillage machine, especially the soil with high hardness is conveniently planted after soil loosening and breaking by rotary tillage.

[0043] Example 1

[0044] like Figures 1-5 As shown, a high-efficiency soil pulverizing rotary tillage device includes a frame 1. The specific structure of the frame 1 is as follows: the frame includes frame sections spaced apart on the left and right sides. Each frame section includes bearing frames 12 that are rotatably connected to the rotary tillage shaft and the pulverizing roller. A bottom beam plate 11 is fixedly connected to the bottom of the bearing frames 12. Furthermore, to prevent soil splashing during the soil pulverization process, the frame 1 also includes dust covers 2 fixedly connected between the bearing frames 12.

[0045] The bearing bracket 12 is fixedly connected to the inner wall of the dust cover 2 by a connecting stiffener 13. A mounting plate is welded onto the connecting stiffener 13 on the front side in the conventional manner, and the machine is mounted to the frame of the rotary tiller by the mounting plate.

[0046] The aforementioned frame 1 is equipped with a rotary tillage and harrow mechanism 4 and a soil crushing mechanism 5. Specifically, the rotary tillage and harrow mechanism 4 includes a rotary tillage shaft 41 (same as in the existing method, with the two ends of the rotary tillage shaft 41 fixedly connected to a rotating shaft, which is rotatably connected to a bearing frame 12), and a number of rotary tillage blade structures are fixedly assembled and connected to the rotary tillage shaft 41.

[0047] Specifically, the rotary tiller structure includes a female mounting base 42 fixedly mounted on the rotary tiller shaft 41 and a female mounting base 43 slidably mounted on the rotary tiller shaft 41. A plurality of rotary tillers 44 are disposed in the gap between the female mounting base 42 and the female mounting base 43. The female mounting base and the female mounting base are locked together by a plurality of locking screws, which secure the rotary tillers 44. The locking screws pass through the rotary tillers 44. Nuts are installed at both ends of the locking screws.

[0048] The aforementioned soil shredding mechanism 5 includes a shredding roller 51 rotatably connected to the frame (similarly, the two ends of the shredding roller 51 are fixedly connected to a rotating shaft, which is rotatably connected to a bearing bracket 12). Two shredding corrugated plates 52 are mounted on the shredding roller 51. The shredding corrugated plates 52 are symmetrically distributed on the front and rear sides of the shredding roller 51.

[0049] Meanwhile, the shredding corrugated board 52 is elastically and slidably connected to the shredding roller 51 through several elastic structures 54.

[0050] Specifically, the convex surface of the corrugated sheet 52 faces outward, and the concave surface of the corrugated sheet 52 faces inward; the elastic structure 54 includes a spring seat fixedly connected to the concave surface of the corrugated sheet 52, a spring slide rod fixedly connected to the spring seat, and the spring slide rod slidably connected to the shredding roller 51 (the shredding roller 51 has a suitable sliding cavity); a spring is sleeved on the spring slide rod, and the two ends of the spring are fixedly connected to the spring seat and the shredding roller 51 respectively.

[0051] Meanwhile, several arc-shaped blade structures 53 are fixedly connected to the corrugated sheet 52 (the arc-shaped blade structures 53 are distributed along the length direction of the corrugated sheet 52). The arc-shaped blade structure 53 includes an arc-shaped blade holder 531 (welded to the corrugated sheet 52 by welding), and several shredding teeth 532 are integrally formed on the arc-shaped blade holder 531. Specifically, the shredding teeth 532 are arc-shaped distributed on the arc-shaped blade holder 531; the cross-sectional shape of the shredding teeth 532 is triangular.

[0052] During the rotary tillage operation, the rotary tillage harrow mechanism 4 first initially tills and breaks up the soil. After tillage and breaking, the soil with a high degree of hardening is tilled into a large number of soil clods. At this time, the crushing corrugated plate 52 located at the rear presses against the soil clods while rotating. During this process, the spring is compressed. Subsequently, the arc-shaped blade holder 531-crushing tooth 532 structure further breaks up the soil.

[0053] When one side of the corrugated crushing plate 52 is under elastic compression, the soil is further finely crushed by the arc-shaped blade holder 531 and crushing teeth 532 after rapid soil breaking. The elastically configured corrugated crushing plate 52, while rotating, repeatedly switches and elastically compresses the soil, thus achieving further thorough crushing and refinement of soil that has not been sufficiently broken down by rotary tillage. Specifically, during rotation, the corrugated crushing plate 52 rolls and kneads the soil using an elastic contact method. During this kneading process, the crushing teeth 532 break the soil, achieving high crushing efficiency and thorough crushing through this kneading and pressing method.

[0054] The aforementioned rotary tillage mechanism 4 and soil shredding mechanism 5 are connected by a pulley drive structure 6. Specifically, the pulley drive structure 6 includes drive pulleys 62 (mounted on the shaft) respectively installed on the shredding roller 51 and the rotary tillage shaft 41. The drive pulleys 62 are connected by a drive belt. The pulley drive structure 6 also includes a driven pulley 61 installed at the other end of the shredding roller 51. Following conventional methods disclosed in the prior art, the pulley drive structure also includes a pulley motor (similar to existing rotary tillers, the motor is mounted on the frame of the rotary tiller, not shown in the figure). A driving pulley connected to the driven pulley 61 via a drive belt is installed on the output shaft of the pulley motor.

[0055] The aforementioned belt drive structure enables the rotary tillage and harrow mechanism 4 and the soil crushing mechanism 5 to rotate synchronously and work together to fully break up the soil.

[0056] Example 2

[0057] like Figures 1-5 As shown, based on the structure of Embodiment 1, the above-mentioned high-pulverization rotary tillage device further includes a trailing pulverizing structure located behind the soil crushing mechanism 5. The trailing pulverizing structure achieves further pulverization of the soil already broken by the rotary tillage harrow mechanism 4 and the soil crushing mechanism 5 through trailing roller pressing pulverization.

[0058] Specifically, the trailing shredding structure includes a trailing roller 31, on which a plurality of trailing shredding teeth 32 are welded. The trailing shredding teeth 32 are crescent-shaped and are distributed circumferentially and axially on the trailing roller 31.

[0059] Meanwhile, the two ends of the trailing roller 31 are rotatably connected to hinge seats 33 (similarly, the two ends of the trailing roller 31 are fixedly connected to rotating shafts, and the rotating shafts are rotatably connected to hinge seats 33). The hinge seats 33 are hinged to the connecting stiffener plate 13 at the rear end by pins.

[0060] Under the action of gravity, the trailing roller 31 supports the soil and moves forward with the rotary tiller (in the current way, the entire device is installed on the frame of the rotary tiller), pulling the soil. During the pulling process, the trailing roller 31 rotates, and the trailing crushing teeth 32 further refine the soil. In this way, in conjunction with the above-mentioned rotary tillage harrow mechanism 4 and soil crushing mechanism 5, the soil is thoroughly crushed.

[0061] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
