Technical Field
[0001] This utility model belongs to the technical field of rotary tillage, ridging and mulching machine, and particularly relates to a multi-functional spring sweet potato rotary tillage, ridging and mulching machine. Background Technology
[0002] Spring sweet potatoes are widely cultivated due to their high starch content and high yield per acre. Planting typically begins in March or April. Before planting, the soil is first loosened using rotary tillage machinery, and then ridged and compacted using a ridging machine. Currently used multi-functional spring sweet potato rotary tillage, ridging, and mulching machines include a frame, a rotary tillage mechanism with rotary tillage wings near the front of the frame, a ridging mechanism behind the rotary tillage mechanism, a mulch film roll frame and a sprinkler belt frame behind the ridging mechanism, and a soil-burying shaft with a soil-pulling plate between the ridging and rotary tillage mechanisms. The rotary tillage mechanism loosens the soil, the ridging mechanism of the spring sweet potato rotary tillage, ridging, and mulching machine forms ridges, the sprinkler belt and mulch film are laid on the ridges, and the soil-burying shaft spreads the loosened soil evenly over the laid mulch film and sprinkler belt. The above-mentioned rotary tillage, ridging, and mulching machine for spring sweet potatoes has the following defects: Firstly, after the rotary tiller tills, the soil-burying shaft spreads the soil evenly over the mulch film. The sweet potato seedlings are planted on both sides close to the ridge. Because the spring sweet potato planting season is early and the soil temperature is low, the sun shines on the soil above the mulch film, and the mulch film has a heat insulation effect. The soil temperature below the mulch film is low, which is not conducive to the growth and development of sweet potatoes. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a multifunctional spring sweet potato rotary tillage, ridging and mulching machine that is buried on both sides of the mulch film, which heats up the soil quickly and is conducive to the rooting and sprouting of sweet potatoes.
[0004] To solve the above problems, the technical solution adopted by this utility model of a multifunctional spring sweet potato rotary tillage, ridging, and mulching machine is as follows: It includes a frame, a rotary tillage mechanism with rotary tillage wings is provided near the front of the frame, a ridging mechanism is provided behind the rotary tillage mechanism, a mulch film roll frame and a sprinkler belt frame are provided behind the ridging mechanism, a soil-burying shaft with a soil-pulling plate is provided between the ridging mechanism and the rotary tillage mechanism, a soil-dividing mechanism is provided above the ridging mechanism, the soil-dividing mechanism includes a vertical support rod located in the middle, a hinge is provided on the vertical support rod, two soil-dividing plates are provided on the hinge, a connecting ring is provided behind the two soil-dividing plates, and a telescopic rod is provided between the two connecting rings.
[0005] Its additional technical features are:
[0006] A soil-pulling plate seat is provided on the soil-burying shaft. A strip-shaped hole is provided on the soil-pulling plate seat. A circular hole is provided on the soil-pulling plate. An adjusting bolt is provided in the strip-shaped hole and the circular hole.
[0007] The soil-removing plate seat is at a certain angle to the axial direction of the soil-burying shaft, and the soil-removing plate seats on both sides of the vertical support rod are symmetrical with respect to the radial plane where the vertical support rod is located.
[0008] Compared with existing technologies, the multifunctional spring sweet potato rotary tillage, ridging, and mulching machine provided by this utility model has the following advantages: Firstly, it includes a frame, a rotary tillage mechanism with rotary tillage wings is set near the front of the frame, a ridging mechanism is set behind the rotary tillage mechanism, a mulch film roll frame and a sprinkler belt frame are set behind the ridging mechanism, a soil-burying shaft with soil-dispensing plates is set between the ridging mechanism and the rotary tillage mechanism, and a soil-dividing mechanism is set above the ridging mechanism. The soil-dividing mechanism includes a vertical support rod located in the middle, a hinge is set on the vertical support rod, two soil-dividing plates are set on the hinge, a connecting ring is set behind the two soil-dividing plates, and a telescopic rod is set between the two connecting rings. Firstly, according to the soil moisture, soil quality, and crop rotation, the opening angle of the two soil-dividing plates is adjusted by adjusting the length of the telescopic rod, so that the soil thrown out by the soil-burying shaft is close to the mulch film on both sides above the ridge, forming two soil bands near the outer side above the mulch film, while there is almost no soil above the mulch film near the middle of the ridge. Covering the soil has several advantages. First, during sunny days, black plastic film effectively absorbs solar heat, while white film allows sunlight to penetrate and reach the soil beneath, leading to rapid soil warming. At night, the film effectively prevents heat loss, further promoting rapid soil warming and facilitating sweet potato rooting and sprouting. Second, the presence of a soil-pulling plate seat on the burying shaft, with strip-shaped holes and circular holes on the soil-pulling plate itself, along with adjusting bolts, allows for adjustment of the soil-pulling plate's height on the burying shaft based on soil moisture, soil type, and crop rotation, effectively regulating the thickness of the soil covering the plastic film and making it more convenient to use. Third, because the soil-pulling plate seat is at an angle to the axis of the burying shaft, and the soil-pulling plate seats on both sides of the vertical support rod are symmetrical with respect to the radial plane of the vertical support rod, soil in the middle of the axial direction can be pulled outwards, resulting in a flatter ridge and more uniform soil distribution in the soil band above the plastic film.

[0013] The structure and operating principle of this multifunctional spring sweet potato rotary tillage, ridging, and mulching machine will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0014] like Figure 1 and Figure 2 The diagram shows the structure of the multifunctional spring sweet potato rotary tillage, ridging, and mulching machine of this utility model. The machine includes a frame 1, a rotary tillage mechanism 3 with rotary tillage wings 2 near the front of the frame 1, a ridging mechanism 4 behind the rotary tillage mechanism 3, a mulch film roll frame 5 and a sprinkler belt frame 6 behind the ridging mechanism 4, a soil-burying shaft 8 with a soil-pulling plate 7 between the ridging mechanism 4 and the rotary tillage mechanism 3, and a soil-dividing mechanism 9 above the ridging mechanism 4. The soil-dividing mechanism 9 includes a vertical support rod 10 in the middle, a hinge 11 on the vertical support rod 10, two soil-dividing plates 12 on the hinge 11, a connecting ring 13 behind the two soil-dividing plates 12, and a telescopic rod 14 between the two connecting rings 13.
[0015] First, based on soil moisture, soil quality, and crop rotation, the angle of the two soil-separating plates 12 is adjusted by adjusting the length of the telescopic rod 14. This allows the soil thrown out by the soil-burying shaft to be close to the plastic film on both sides above the ridge, forming two soil bands on the outer side of the plastic film. There is almost no soil covering on the plastic film near the middle of the ridge. On sunny days, the black plastic film can effectively absorb the heat of sunlight, while the white plastic film allows sunlight to penetrate and reach the soil below, resulting in a rapid increase in soil temperature. At night, the plastic film effectively prevents heat loss, and the rapid increase in soil temperature is beneficial for sweet potato rooting and sprouting.
[0016] like Figure 3 and Figure 4 As shown, a soil-lifting plate seat 15 is provided on the soil-burying shaft 8, a strip-shaped hole 16 is provided on the soil-lifting plate seat 15, and a circular hole 17 is provided on the soil-lifting plate 7. Adjusting bolts 18 are provided in the strip-shaped hole 16 and the circular hole 17. The height of the soil-lifting plate 7 on the soil-burying shaft 8 can be adjusted according to the soil moisture, soil quality, and stubble conditions, effectively adjusting the thickness of the soil covering the mulch film, making it more convenient to use.
[0017] The soil-pulling plate seat 15 is at a certain angle to the axis of the soil-burying shaft 8, and the soil-pulling plate seats 15 on both sides of the vertical support rod 10 are symmetrical with respect to the radial plane where the vertical support rod 10 is located. This can pull the soil in the middle position of the axis outward, making the ridge flatter and the soil in the soil strip above the mulch film more uniform.
[0018] The scope of protection of this utility model is not limited to the above embodiments. Any structure that is the same as or similar to the structure of this utility model's multifunctional spring sweet potato rotary tillage, ridging, and mulching machine falls within the scope of protection of this utility model.
