Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to a novel rotary tillage and mulching machine for sweet potatoes. Background Technology

[0002] In sweet potato cultivation, ridging, laying drip irrigation tape, and mulching are key steps to ensure high yields. Ridging increases soil aeration and soil temperature, while also facilitating drainage and flood prevention, providing a suitable environment for sweet potato tuber growth. Laying drip irrigation tape enables precise irrigation, reduces water waste, and ensures adequate water supply during sweet potato growth. Mulching effectively suppresses weed growth, reduces soil moisture evaporation, and further increases soil temperature, promoting early and rapid growth of sweet potatoes.

[0003] While existing agricultural machinery includes equipment capable of ridging and mulching, in actual sweet potato cultivation, these devices often cannot simultaneously complete the integrated operation of ridging, drip irrigation tape laying, and mulching. Specifically, existing equipment typically performs ridging first. After ridging, drip irrigation tape needs to be laid manually or using separate equipment on the ridges. Only after the drip irrigation tape is laid is the mulching machine used for covering. This step-by-step operation has significant drawbacks: firstly, multiple separate operations require repeated equipment adjustments or a large investment of manpower, increasing the labor intensity of planting, extending the operation cycle, and reducing planting efficiency; secondly, during the step-by-step operation, the position of the drip irrigation tape is easily shifted due to manual operation or subsequent equipment work, affecting irrigation effectiveness. Furthermore, the compaction of the soil from multiple operations may damage the shape and structure of the ridges, which is detrimental to sweet potato growth.

[0004] Therefore, in view of the problems of cumbersome and inefficient operations of sweet potato planting, such as ridging, laying drip irrigation tape, and mulching in existing technologies, there is an urgent need to develop a new type of rotary tillage sweet potato ridging and mulching machine that can integrate the ridging, drip irrigation tape laying, and mulching processes into one, so as to simplify the operation process, improve planting efficiency, and ensure the quality of sweet potato planting. Utility Model Content

[0005] To improve the planting efficiency of sweet potatoes, this application provides a novel spray-rotary tillage sweet potato ridging and mulching machine.

[0006] The novel rotary tillage sweet potato ridging and mulching machine provided in this application adopts the following technical solution: A novel rotary tillage sweet potato ridging and mulching machine includes a frame. The lower end of the frame is provided with a rotary tillage component and a ridging component for forming soil ridges. The front end of the frame is equipped with a fertilizer box for adding fertilizer into the rotary tillage component. The upper end of the frame is equipped with a drip irrigation tape support frame, on which a drip irrigation tape roll is placed.

[0007] By adopting the above technical solution, the machine frame can be attached to the tractor body. The rotary tiller then tills the land, and fertilizer is added during the tilling process via a fertilizer bin to improve soil fertility. Simultaneously, the ridging component shapes the soil ridges, and the drip irrigation tape support frame and guide wheels work together to lay the drip irrigation tape. Then, the mulch film support frame and mulch film roll cover the drip irrigation tape and soil ridges with mulch film, and the rotary tiller component covers some of the loose soil kicked up by the mulching machine.

[0010] Optionally, the height of the second rotary tiller blade is higher than that of the first rotary tiller blade.

[0011] By employing the above-mentioned technical solution, the first rotary tiller blade tills the soil, loosening and breaking it up. Subsequently, the second rotary tiller blade lifts the topsoil, allowing it to fall onto the mulch film covering the soil ridges.

[0012] Optionally, a guide plate is provided below the guide wheel, and the guide plate is fixedly connected to the frame.

[0013] By adopting the above technical solution, the drip irrigation tape can be guided, making the drip irrigation tape laying process more stable and smooth.

[0014] Optionally, the ridging assembly includes multiple pairs of ridging plates, each ridging plate including two oppositely arranged ridging plates with their ends close to each other, and the ridging plates are fixedly connected to the frame.

[0015] By adopting the above technical solution, soil ridges can be formed, realizing the ridge-making operation of sweet potatoes.

[0016] Optionally, the mulch film support frame is configured as two, and each of the two mulch film support frames is rotatably connected to a mulch film support guide wheel at one end that is close to the other.

[0017] By adopting the above technical solutions, the plastic film can be supported and guided, making the laying of the plastic film more stable and smooth.

[0018] Optionally, a guide cover for guiding the soil direction is provided above the second rotary tiller blade, the guide cover is fixedly connected to the frame, and the guide cover is located at the rear end of the frame.

[0019] By adopting the above technical solution, a guide cover is set above the second rotary tiller blade to guide the direction of the soil, so that the soil lifted by the second rotary tiller blade can fall more accurately onto the laid film.

[0020] Optionally, the ridging board is configured as a corner board, and a reinforcing plate is fixedly connected to the corner of the corner board.

[0021] By adopting the above technical solution, a reinforcing plate can be set at the corner of the corner plate to enhance the structural strength of the ridging plate and improve the durability of the ridging components.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. It integrates multiple functions such as rotary tillage, ridging, fertilization, drip irrigation tape laying and mulching, improving the efficiency of sweet potato planting operations and reducing labor intensity and planting costs; 2. The fertilizer bin allows fertilizer to be added to the rotary tiller assembly, enabling precise fertilization, avoiding fertilizer waste, and improving fertilizer utilization. 3.

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0025] The embodiment of this application is: a novel rotary tillage sweet potato ridging and mulching machine, referring to... Figure 1 The system includes a frame 1, which is connected to a tractor body (not shown in the figure). A rotary tillage assembly 2 is located at the lower end of the frame 1, and a fertilizer box 3 for adding fertilizer to the rotary tillage assembly 2 is installed at the front end of the frame 1. The fertilizer box 3 is a conventional fertilizer box 3, which generally includes a box body, a discharge port located at the bottom of the box body, and an opening and closing device for controlling the opening and closing of the discharge port, enabling the addition of fertilizer to the soil.

[0026] Reference Figure 1 and Figure 2 The rotary tillage assembly 2 includes a first rotary tillage blade 21 and a second rotary tillage blade 22 rotatably connected to the lower end of the frame 1. The first rotary tillage blade 21 is located at the front end of the frame 1, which is the end of the frame 1 closest to the tractor body, and the height of the second rotary tillage blade 22 is higher than that of the first rotary tillage blade 21.

[0027] The rotary tillage assembly includes a gearbox 27 mounted on the frame 1. The gearbox 27 is an agricultural machinery gearbox found in existing agricultural machinery equipment. Its internal gearbox housing is connected to the drive shaft of the towing machinery, providing stable power. The gearbox 27 is connected to the first rotary tiller blade 21 via an integrated gear transmission as in the prior art. The two ends of the gearbox 27 are connected to the first sprocket 23 via connectors. Both ends of the second rotary tiller blade 22 are provided with bearing seats 25. The bearing seats 25 are mounted on the frame 1 and connected to the shaft of the second rotary tiller blade 22. A second sprocket 24 is mounted on the bearing seat 25, and a chain 27 is sleeved between the second sprocket 24 and the first sprocket 23.

[0028] During the transmission process of the gearbox 27, the gearbox 27 can drive the first rotary tiller blade 21 to rotate, and then drive the second rotary tiller blade 22 to rotate through the chain 26. The first rotary tiller blade 21 tills the soil, loosening and breaking it up. Since the second rotary tiller blade 22 is higher than the first rotary tiller blade 21, the second rotary tiller blade 22 will lift up the surface soil. At the same time, in order to limit the direction of soil lifting, a guide cover 13 is provided above the second rotary tiller blade 22 to guide the direction of the soil. The guide cover 13 is fixedly connected to the frame 1 and is located at the rear end of the frame 1.

[0029] A drip irrigation tape support frame 5 is installed at the upper end of the frame 1, and a drip irrigation tape roll 6 is placed on the drip irrigation tape support frame 5. The drip irrigation tape roll 6 can be rotated. Two drip irrigation tape guide wheels 7 are provided on the lower side of the frame 1. The end of the drip irrigation tape in the drip irrigation tape roll 6 is placed on the drip irrigation tape guide wheels 7. A guide plate 11 is provided below the guide wheels 7, and the guide plate 11 is fixedly connected to the frame 1.

[0030] The frame 1 is equipped with a ridging assembly 4 for forming soil ridges. The ridging assembly 4 includes multiple pairs of ridging plates 41. Each ridging plate 41 includes two oppositely arranged ridging plates 41. In this embodiment, the ridging plates 41 are corner plates, and a reinforcing plate 14 is fixedly connected to the corner of the corner plate. The two ridging plates 41 extend from the side away from their traction end to the side that is closer to each other. The ridging plates 41 are fixedly connected to the frame 1. A plastic film support frame 9 is installed at the tail end of the frame 1. There are two plastic film support frames 9, and each of the two plastic film support frames 9 is rotatably connected to a plastic film support guide wheel 12 at the end that is closer to each other. A plastic film roll 10 is rotatably connected to the plastic film support guide wheel 12 on the plastic film support frame 9.

[0031] Thus, when the frame 1 moves, the drip irrigation tape support frame 5 and the guide wheel 7 work together to lay the drip irrigation tape. Then, the mulch film support frame 9 and the mulch film roll 10 can cover the mulch film, covering the drip irrigation tape and the soil ridges, and the rotary tillage component 2 can cover some of the soil on the loose soil raised by the mulching machine.

[0032] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
