Description

Technical Field

[0001] The present invention specifically relates to a soil-covering machine for agricultural planting and a use method thereof, and belongs to the technical field of agricultural machinery. Background Art

[0002] In agricultural production, when planting watermelon, tobacco, sweet potato, strawberry, etc., it is necessary to make ridges, which is convenient for covering with film and walking during operation. At the same time, the ridges are higher than the gullies between the ridges, which makes it convenient to walk between the gullies to operate the crops on the ridges. After the soil is turned over, it can alleviate the compaction of the soil and improve the soil structure.

[0003] For example, the Chinese invention patent application document, with publication number CN117178669A, discloses a soil-turning equipment for agricultural planting, including an operating body, an operating handle fixed on the operating body, a mounting groove opened on the operating body, U-shaped frames are arranged on both sides of the mounting groove, the U-shaped frames are fixed to the upper end of the operating body, two mounting frames are connected to the two U-shaped frames through a lifting assembly and a guide assembly, and a soil-turning assembly for turning the soil and a filtering and moving-up assembly for filtering and moving up stones inside the soil after turning the soil are arranged between the two mounting frames.

[0004] The above document can not only achieve the requirement of turning the soil, but also cover the mixed stones on the upper surface of the soil through the mutual cooperation of the lifting component, the guide component, the soil turning component and the filtering and moving component, so as to facilitate efficient and high-quality planting operations in agriculture. However, the above equipment only performs the soil turning operation, and filters out large pieces of debris and then transfers them to the upper surface of the soil. However, the soil surface after turning the soil is uneven and does not form ridges, and subsequent equipment is required to perform trenching and soil covering operations.

[0005] There are also many agricultural machines on the market that can both tillage and form ridges at the same time, but their fixed structures are difficult to adjust, and the ends of the ridges may be uneven or out of place. If complete ridges need to be formed on the field, the tillage range needs to be extended, but this will damage the road surface next to the field. Therefore, how to ensure the neatness of the ends of the ridges when they are formed and improve their utilization rate is an urgent problem that technicians in this field need to solve.

[0014] A second power wheel is fixed on the upper surface of the bracket, the second power wheel is connected to the first power wheel through a power belt, and an eccentric disk is fixed on one side of the second power wheel, and an eccentric shaft is fixed on the eccentric disk.

[0016] The method for using a soil-turning and covering machine for agricultural planting comprises the following steps:

[0017] In the initial state, under the pulling force of the pulling rope, the rotating rod flips to the left, and the two side plowshares face the front and rear sides of the main plowshare;

[0018] During the tillage operation, the pulling rope is released according to the movement intention of the lifting mechanism of the agricultural machine, and the lifting mechanism on the agricultural machine drives the connecting rod to be lowered close to the land, and then the agricultural machine is pulled to the left, and the main plowshare turns the soil in the middle and turns it to both sides, and the side plowshare turns around the cross bar due to the friction of the soil on the spot, and slowly inserts into the soil with the movement of the main plowshare, turning the soil on both sides to the middle, until it returns to the initial position and moves horizontally to the left to turn the soil;

[0019] During the ploughing process, as the agricultural machine is continuously moving, the contact wheel starts to rotate after being rubbed by the soil, and then the eccentric disk is rotated through the power transmission of the power belt, driving the reciprocating block and the anti-bow plate to move up and down. The turning effect of the main plowshare and the side plowshare is limited, and the soil is still in a clumping state. The reciprocating vertical cutting plate can crush the soil;

[0020] In the end state, after the main plowshare reaches the head of the field, the lifting mechanism drives the connecting rod and the main plowshare to rise until the main plowshare is higher than the field ridge after turning the soil, and then stops moving upward. Then the agricultural machine continues to move, driving the side plowshare to turn the soil until it reaches the end of the field ridge. The lifting mechanism moves upward, and the pulling rope pulls the side plowshare up, slides out of the soil, and gradually flips over and receives the front and rear sides of the main plowshare to reach the initial position.

[0021] The technical effects and advantages of the present invention are as follows: when the soil-turning and covering machine is in use, it needs to be installed on the lifting mechanism of the agricultural machinery. Initially, under the pulling force of the pull rope, the rotating rod flips to the left, and the two side plowshares face the front and rear sides of the main plowshare. At this time, the side plowshares are higher than the main plowshare. The lifting mechanism on the agricultural machinery drives the connecting rod to be lowered, and then the agricultural machinery is pulled to the left, the main plowshare turns the soil in the middle and turns to both sides, and the side plowshares turn around the crossbar on the spot due to the friction of the soil, and as the main plowshare moves slowly, the side plowshares turn around the crossbar. Slowly insert the soil, turn the soil on both sides to the middle, until it returns to the initial position and then moves horizontally to the left to turn the soil. After the main plowshare reaches the head of the field, the lifting mechanism drives the connecting rod and the main plowshare to rise until the main plowshare is higher than the ridge after turning the soil, and then stops moving up. Then the agricultural machine continues to move, driving the side plowshare to turn the soil until it reaches the end of the ridge. The lifting mechanism moves up, the pull rope pulls the side plowshare up, slides out of the soil, and gradually turns over the front and rear sides of the main plowshare to reach the initial position. This ensures that when it reaches the end, the tail can be kept neat and neat at the beginning. It is different from traditional equipment, which is separated from the left and right at the beginning. When the main plowshare plows, the side plowshare also starts to plow the land, resulting in an effective turning length greater than the original ridge length, and the middle of the starting section is not plowed up. At the end, there is still a part that has not been plowed in place, and it is impossible to form a ridge. The soil turning and covering machine can show better results, ensure the end is neat, and can also refine the soil when plowing, which is beneficial to agricultural planting.

[0038] The method for using a soil-turning and covering machine for agricultural planting comprises the following steps:

[0039] In the initial state, under the pulling force of the pulling rope 81, the rotating rod 502 flips to the left, and the two side plowshares 7 face the front and rear sides of the main plowshare 3;

[0040] During the tillage operation, the pulling rope 81 is released according to the movement intention of the lifting mechanism of the agricultural machine, and the lifting mechanism on the agricultural machine drives the connecting rod 2 to be lowered close to the land, and then the agricultural machine is pulled to the left, and the main plowshare 3 turns the soil in the middle and turns it to both sides, and the side plowshare 7 turns around the crossbar 501 due to the friction of the soil at the original place, and slowly inserts into the soil with the movement of the main plowshare 3, turning the soil on both sides to the middle, until it returns to the initial position and moves horizontally to the left to turn the soil;

[0041] During the ploughing process, as the agricultural machine is continuously moving, the contact wheel 602 starts to rotate after being rubbed by the soil, and then the eccentric disc 605 is rotated through the power transmission of the power belt 604, driving the reciprocating block 607 and the anti-bow plate 608 to move up and down. The turning effect of the main plowshare 3 and the side plowshare 7 is limited, and the soil is still in a clumping state. The reciprocating vertical cutting plate 609 can crush the soil;

[0042] In the end state, after the main plowshare 3 reaches the head of the field, the lifting mechanism drives the connecting rod 2 and the main plowshare 3 to rise until the main plowshare 3 is higher than the field ridge after turning the soil, and then stops moving upward. Then the agricultural machine continues to move, driving the side plowshare 7 to turn the soil until it reaches the end of the field ridge. The lifting mechanism moves upward, and the pulling rope 81 pulls the side plowshare 7 up, slides out of the soil, and gradually flips over and receives the front and rear sides of the main plowshare 3 to reach the initial position.

[0043] When the soil-turning and covering machine is in use, it needs to be installed on the lifting mechanism of the agricultural machinery. Initially, under the pulling force of the pull rope, the rotary rod 502 flips to the left, and the two side plowshares 7 face the front and rear sides of the main plowshare 3. At this time, the side plowshares 7 are higher than the main plowshare 3. The lifting mechanism on the agricultural machinery drives the connecting rod 2 to be lowered, and then the agricultural machinery is pulled to the left, and the main plowshare 3 turns the soil in the middle and turns to both sides. The side plowshares 7 turn around the crossbar 501 due to the friction of the soil in the original place, and are slowly inserted into the soil as the main plowshare 3 moves. The main plowshare 3 enters the soil and turns the soil on both sides toward the middle until it returns to the initial position and then moves horizontally to the left to turn the soil. After the main plowshare 3 reaches the head of the field, the lifting mechanism drives the connecting rod 2 and the main plowshare 3 to rise until the main plowshare 3 is higher than the field ridge after turning the soil, and then stops moving upward. Then the agricultural machine continues to move, driving the side plowshare 7 to turn the soil until it reaches the end of the field ridge. The lifting mechanism moves upward, and the pull rope pulls the side plowshare 7 to rise, slide out of the soil, and gradually turn over the front and rear sides received by the main plowshare 3 to reach the initial position. This ensures that when it reaches the end, the tail can be kept neat and tidy at the beginning. It is different from traditional equipment, which is separated from the left and right at the beginning. When the main plowshare 3 plows, the side plowshare 7 also starts plowing, resulting in the effective soil turning length being greater than the original ridge length, and the middle part of the starting section is not plowed up. At the end, there is still a part that has not been plowed in place and no ridge can be formed. The present soil turning and covering machine can show better effect, ensure the neatness of the end, and can also refine the soil when plowing, which is beneficial to agricultural planting.

The reciprocating vertical cutting plate (609) can crush the soil; In the end state, after the main plowshare (3) reaches the head of the field, the lifting mechanism drives the connecting rod (2) and the main plowshare (3) to rise until the main plowshare (3) is higher than the field ridge after turning the soil, and then stops moving upward. Then the agricultural machine continues to move, driving the side plowshare (7) to turn the soil until it reaches the end of the field ridge. The lifting mechanism moves upward, and the pulling rope (81) pulls the side plowshare (7) up, slides out of the soil, and gradually turns over and receives the front and rear sides of the main plowshare (3) to reach the initial position.
