Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a sugarcane stubble leveling device for hillside land. Background Technology

[0002] Sugarcane is a perennial root crop grown on raised beds. After the previous year's sugarcane harvest, the sugarcane stubble left in the raised bed will sprout and grow into sugarcane plants under suitable environmental conditions. With proper management, a single planting can sustain harvesting for 3-5 years.

[0003] In agricultural machinery classification, the coppicing machine for ratooned sugarcane belongs to the field management category. It is a very important agronomic process for ratooned sugarcane. After manual or mechanical harvesting, the sugarcane stubble left for ratooning is uneven, which affects the development of ratooned plants and the growth of subsequent sugarcane. If it is not coppiced, the sugarcane stalks exposed above ground are easily affected by frost, pests, etc., which can affect the germination of underground buds at the base of the ratooned sugarcane. Alternatively, the sugarcane buds above ground may grow rapidly, but without soil cover around the roots, they will not receive sufficient nutrients during the growth process, which can lead to the death of the sugarcane seedlings and the failure of the seedlings to grow into sugarcane stalks, thus affecting the sugarcane yield.

[0004] In order to perform stubble cutting on the ratooned sugarcane after harvest, the existing stubble cutting devices on the market cannot adjust the spacing and height of the stubble cutting blades, which limits their applicability. They also cannot level the ridge height, and a lot of time is still needed to level the ridge height after stubble cutting, which is time-consuming and labor-intensive. Utility Model Content

The connecting rod 331 is slidably connected inside the rotating cylinder 32, and its upper end passes through the rotating cylinder 32 to the outside. A cutter 332 is fixedly connected to the lower end of the rotating rod 33. The rotation of the rotating cylinder 32 drives the connecting rod 331 to rotate, the connecting rod 331 drives the rotating rod 33 to rotate, and the rotating rod 33 drives the cutter 332 to rotate, thereby making a flat cut on the sugarcane rootstock.

One end of pull block 62 is connected to a tension adjuster 63. The tension adjuster 63 is connected to the side of the frame 1 at one end of pull block 62. A third pulley 611 is fixedly connected to tension rod 61. The third pulley 611 is connected to the belt 321 connected to the first pulley 241 and the second pulley 322. The tension adjuster 63 drives the pull block 62 to move, the pull block 62 drives the tension rod 61 to move, and the tension rod 61 drives the third pulley 611 to move, thereby tightening the belt 321.

The circular connecting platform 3311 is slidably connected in the rail groove 421. The limiting groove 422 and the limiting platform 422 are connected to the upper side of the frame 1 via the rail groove 123. The circular limiting platform 3312, when engaged, allows the circular limiting platform 3312 to slide and rotate within the limiting groove 422. It also prevents the circular limiting platform 3312 from tilting, thereby preventing the connecting rod 331 from tilting and improving the stability of the outer cylinder 31. The height adjuster 41 can drive the adjusting plate 42 to move up and down. The adjusting plate 42, through the circular limiting platform 3312, drives the connecting rod 331 to move up and down. The connecting rod 331 drives the rotating rod 33 to move up and down. The rotating rod 33 drives the cutter 332 to move up and down, thereby achieving the adjustment of the vertical distance of the cutter 332.

[0058] The height adjuster 41 can be manual or automatic. If automatic, it can be a mechanism such as a cylinder or a motor screw that can push the connecting block 52 to move. If manual, it can be a screw.

One end of the depth limiting support rod 71 passes through the frame 1 into the drive cavity 12 and is fixedly installed on one side of the frame 1 by the first U-shaped frame 73 and the first nut 74. The other end is rotatably connected to the depth limiting wheel 72. The distance between the depth limiting wheel 72 and the bottom side of the frame 1 can be adjusted by the first U-shaped frame 73 and the first nut 74, and the relative distance between the cutter 332 and the depth limiting wheel 72 can be controlled, so as to adapt to the application on sloping land and not affect the depth of the cutter 332 in soil gathering due to uneven soil.

[0060] refer to Figure 2 , Figure 5 and Figure 9 As shown, four soil-gathering support rods 81 are provided on the frame 1 behind the cutter 332. One end of the soil-gathering support rod 81 passes through the frame 1 to the storage box. The storage box is equipped with a fixing plate. One end of the soil-gathering support rod 81 is fixedly installed on the side of the frame 1 or the fixing plate by the second U-shaped frame 84 and the second nut 85.

The height of the soil-gathering plate 82 can be adjusted by the second U-shaped frame 84, the second nut 85 and the pad 83, so that it can better adapt to the corresponding terrain and ridge height. The spacing between the soil-gathering plates 82 can also be adjusted to adapt to the corresponding ridge width, so that the device has a wide range of applications.

[0061] Among them, the soil-gathering plate 82 can gather the soil on both sides of the sugarcane ridge, increase the height of the sugarcane ridge, and allow the ratoon to be buried in the soil.

[0062] Among them, the pad 83 near the soil-gathering support rod 81 has an arc-shaped groove on the side facing the soil-gathering support rod 81. The arc-shaped groove fits into the soil-gathering support rod 81, improving the stability of the soil-gathering support rod 81.

The other end is rotatably connected to both ends of the rotating frame 91. The rotating frame 91 can level the top of the sugarcane ridge and make the sugarcane ridge height uniform. The leveling support rods 92 can be moved by the third U-shaped frame 93 and the third nut 94, thereby adjusting the height of the rotating frame 91. The rotating frame 91, together with the depth-limiting wheel 72, can keep the frame 1 in a stable state, so that it will not rise and fall excessively due to the undulation of the land, thus facilitating better and more even cutting of the ratoon.
