Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery and equipment, in particular to a device for sowing green manure between rows of corn for cultivation. Background Art

[0002] Corn, one of the world's most important food crops, is widely cultivated worldwide. However, long-term continuous cropping can lead to a partial depletion of nutrients such as nitrogen and potassium in the soil, leading to nutritional imbalances, deterioration of soil physical and chemical properties, reduced soil enzyme activity, imbalanced microbial populations, and the frequent occurrence of certain diseases, seriously affecting corn yields. Green manure, as a complete fertilizer rich in organic matter, can quickly promote the growth of beneficial microorganisms after being incorporated into the soil, improving the soil microbial balance, inhibiting the growth of pathogens, and promoting improvements in soil structure. It also enhances the soil's ability to retain water and fertilizer, thereby addressing the issue of continuous cropping to a certain extent.

[0003] Most current cultivators are capable of combined operations, allowing other devices such as fertilizing, weeding, and seeding equipment to be installed on the cultivator's frame to improve operating efficiency. This approach is also commonly used for inter-row seeding of green manure, with corn and green manure planters installed on the cultivator's frame. However, this places a heavy burden on the cultivator and increases energy consumption. Green manure can be sown either in rows or broadcast, and plant and row spacing do not require specific regulations, eliminating the need for energy-intensive seeding equipment.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1-5 As shown, a green manure equipment for inter-row sowing of corn includes a bracket 1, a green manure box 2 is fixed on the bracket 1, a mounting frame 3 is welded on the outer wall of the outlet end of the green manure box 2, a plurality of movable plates 4 are plugged into the outlet end of the green manure box 2, a feeding hole 5 is opened on the movable plate 4, one end of the movable plate 4 is bolted to the mounting frame 3, a plurality of electric cylinders 6 are installed on the mounting frame 3, a push plate 7 is fixed to the output end of the electric cylinder 6, a proximity switch 8 is installed at one end of the push plate 7, a gear lever 9 is plugged into the mounting frame 3, and two guide plates 10 are welded inside the green manure box 2.

[0027] The movable plate 4 has a solid part and a part with a movable hole. When one end of the movable plate 4 is bolted to the mounting frame 3, the solid part of the movable plate 4 is located above the discharge hole 11, thereby blocking the discharge hole 11 and preventing green manure seeds from falling from the discharge hole 11, which is used to avoid the corn planting rows; when the other end of the movable plate 4 is bolted to the push plate 7 and the electric cylinder 6 is fully extended, the solid part of the movable plate 4 is located above the discharge hole 11, thereby blocking the discharge hole 11, which is used to stop sowing green manure seeds; after the electric cylinder 6 retracts, the discharge hole 5 and the discharge hole 11 partially overlap, and the green manure seeds fall from the overlapping part, which is used for normal sowing of green manure seeds.

[0028] The top of the green manure box 2 is open, and a discharge hole 11 is provided at the discharge end of the green manure box 2. Through holes 12 are provided on both sides of the discharge end of the green manure box 2. Two guide plates 10 are welded obliquely on the inner wall of the discharge end of the green manure box 2. There is a gap at the bottom end of the two guide plates 10 to allow green manure seeds to fall from the green manure box 2 to the movable plate 4.

[0029] The discharge hole 11 is in the shape of an elongated hole and is used to allow the green manure seeds to fall from the discharge hole 11 . The through hole 12 is in the shape of an elongated hole and is used to plug in the movable plate 4 .

[0030] The mounting frame 3 is a square frame structure. A first slot 13 is provided on the inner wall of one side of the mounting frame 3. One end of the movable plate 4 is inserted into the first slot 13 and then bolted to the mounting frame 3. A sleeve 14 is welded to the mounting frame 3, and a limiting bolt 15 is threadedly connected to the outer wall of the sleeve 14.

[0031] The lever 9 is inserted into the mounting frame 3 via a sleeve 14. The tail of the limit bolt 15 abuts the outer wall of the lever 9, aligning the lever 9 with the trigger end of the proximity switch 8. As the electric cylinder 6 retracts, the feed hole 5 of the movable plate 4 gradually moves above the discharge hole 11. Because the width of the feed hole 5 varies, the position of the lever 9 can be adjusted according to the size of the green manure seed and the seeding rate. This ensures that the proximity switch 8 contacts the lever 9 during the retraction of the electric cylinder 6, thereby stopping the retraction.

[0032] The material discharge hole 5 is a long strip structure, and the width of the material discharge hole 5 gradually decreases from one end to the other end.

[0033] A second draw-in slot 16 is provided on one side of the push plate 7. When the movable plate 4 is bolted to the push plate 7, the movable plate 4 is inserted into the second draw-in slot 16.

[0034] The working principle of this utility model is:

[0035] During use, the bracket 1 of the present invention is fixed to the frame of the cultivator, the electric cylinder 6 is electrically connected to the power supply of the cultivator, and the electric cylinder 6 is associated with the proximity switch 8. According to the row spacing of corn planting and the row spacing of the green manure to be sown, the corresponding movable plate 4 is loosened from the bolted part on the mounting frame 3, and its other end is inserted into the second slot 16 of the push plate 7 and bolted to the push plate 7. The limiting bolt 15 on the mounting frame 3 is loosened, and according to the size of the green manure seed and the sowing amount, the shift lever 9 is slid in the sleeve 14 to the corresponding position and the limiting bolt 15 is tightened.

[0036] To begin sowing, pour green manure seeds into the manure tank 2, start the tiller, and activate the electric cylinder 6 to retract. When the proximity switch 8 touches the shift lever 9, the electric cylinder 6 stops retracting. At this point, the feed hole 5 and the discharge hole 11 partially overlap, and the green manure seeds fall from this overlapping area into the soil, thus completing the inter-row sowing of the green manure seeds. To turn, reverse, or otherwise stop sowing, the electric cylinder 6 is controlled to extend. At this point, the feed hole 5 and the discharge hole 11 no longer overlap, and the green manure seeds stop falling.

[0037] The above-described embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.

[0038] The technology, shape and structure that are not described in detail in this utility model are all well-known technologies.
