Description

Technical Field

[0001] The present invention relates to the technical field of agricultural machinery, and in particular to a ground film burying and pressing device and a straw ground film cooperative covering sowing machine. Background Art

[0002] Strip tillage is a conservation tillage technique that focuses on localized tillage within crop strips while retaining the soil in the stubble strips between them (e.g., using straw, stubble, or natural vegetation). This achieves the sustainable agricultural goals of reducing soil disturbance, conserving water and soil, and improving fertilizer efficiency. During strip tillage, mulch film laying equipment is typically used to increase ground temperature within the crop strips and ensure seed and seedling survival rates.

[0003] As in the prior art, the Chinese invention patent with authorization announcement number CN111386945B proposes a device for burying and pressing ground film on a seeding machine. When burying the ground film, a pair of furrowing plows arranged on the left and right sides of the connecting frame plow a ditch on the ground below the two side edges of the ground film before laying the ground film, and uses the ground film initial laying and pressing mechanism to press the ground film unfolded on the ground film roller downward so that it is close to the ground. Then, during the movement of the equipment, the ground film pressing wheel presses the two sides of the laid ground film while rolling, so that the ground film covering plow will cover the plowed pressed soil on the side edges of the ground film laid on the ground, so that the pressed soil sinks into the ditch on the same side together with the side edges of the ground film when pressing the side edges of the ground film, thereby burying and pressing the side edges of the ground film.

[0004] For the device for burying ground film on the above-mentioned seed drill, the fixation of the ground film mainly relies on the friction resistance at the contact interface between the film surface and the soil to achieve positioning. However, due to the smooth surface of the ground film, its lateral anchoring system is difficult to provide sufficient restraint force. When encountering strong winds, it is easy to cause the film layer to peel off and cause structural failure. Summary of the Invention

[0012] The second embodiment of the present invention provides a straw-film coordinated covering seeding machine, which includes the film burying device of the first embodiment of the present invention.

[0013] The ground film burying and pressing device according to the embodiment of the present invention has the following beneficial effects: 1. This device arranges multiple puncturing members on the circumferential side wall of the pressing wheel, which puncture the ground film during the rolling process of the pressing wheel and form multiple incisions on the side of the ground film, so that the soil buried by the covering module on the upper side of the ground film can be combined with the soil on the lower side of the ground film through the incisions, and the cohesive force between the soils is used to strengthen the anchoring effect of the soil on the side of the ground film, effectively improving the problem of poor anchoring effect of the ground film side in the existing technology.

[0014] 2. This device utilizes an assembly component to movably assemble the piercing element in the assembly hole. When the magnetic metal element rolls with the pressing wheel to a position directly below the permanent magnet, the magnetic metal element, under the magnetic attraction of the permanent magnet, drives the piercing element upward for a distance, forming a narrow gap between the outer wall of the piercing element and the inner wall of the assembly hole. The aqueous solution stored in the pressing wheel can flow out through the narrow gap, flushing the piercing element. The aqueous solution flowing along the piercing element into the V-shaped ditch effectively strengthens the soil cohesion.

[0015] 3. This device utilizes a slow-release assembly to assemble a permanent magnet on the bearing shaft to slow down the descent of the permanent magnet under the action of an external force. This allows the magnetic metal part to move upward a certain distance under the magnetic attraction of the permanent magnet when the magnetic metal part follows the pressing wheel and moves to the position directly below the permanent magnet, so that a slit is formed between the outer wall of the piercing part and the inner wall of the assembly hole. As the time it takes for the slit to form between the outer wall of the piercing part and the inner wall of the assembly hole increases, the piston connected to the permanent magnet through the connecting rod gradually slides toward the bottom port of the cylinder until the piercing part, driven by the elastic force of the support spring, blocks the assembly hole. This prevents the assembly hole from being open for too long when the frame body stops moving or moves too slowly, causing excessive outflow of the aqueous solution stored therein and reduced soil cohesion in the V-shaped ditch. 4. This device installs an air pump on the top of the water tank to input air into the pressing wheel through the air pipe and the first guide cavity. It also installs a safety valve on the load-bearing shaft and connects it to the inner cavity of the pressing wheel through the second guide cavity, thereby forming a certain degree of pressure in the inner cavity of the pressing wheel to enhance the sealing effect between the plurality of piercing members and the assembly holes, and the flushing effect of the water flow output through the slit between the piercing members and the assembly holes on the piercing members.

The bottom end of the piercing member 3 is provided with a blade portion 31, and the bottom end of the piercing member 3 protrudes from the pressing wheel 2. The circumferential side wall surface of the wheel 2; the fixed bracket 672 is fixedly set on the inner wall of the pressing wheel 2, the fixed bracket 672 matches the position of the assembly hole 671, and the fixed bracket 672 is slidably connected to the piercing member 3; the support spring 673 is fixedly set on the fixed bracket 672, the elastic force of the support spring 673 is greater than the elastic force of the return spring 653, and the support spring 673 is connected to the top of the piercing member 3 for elastically supporting the piercing member 3; the movable bracket 674 is fixedly set on the piercing member 3 for driving the piercing member 3 to slide; the magnetic metal part 675 is fixedly set on the top of the movable bracket 674 for driving the movable bracket 674 to move.

[0027] Further, if Figure 3 、 6 As shown in Figures 7 and 8, a first sealing protrusion 32 is fixedly provided on the circumferential outer wall of the piercing member 3, a sealing ring 33 is fixedly sleeved on the circumferential outer wall of the piercing member 3, and a second sealing protrusion 6711 is fixedly provided on the circumferential inner wall of the assembly hole 671. Driven by the elastic force of the supporting spring 673, the piercing member 3 drives the first sealing protrusion 32 to cooperate with the second sealing protrusion 6711, and squeezes the sealing ring 33, so as to achieve the purpose of sealing the gap between the piercing member 3 and the assembly hole 671 by using the sealing ring 33. Further, if Figure 1 As shown, the covering module 4 includes: a covering plate 41 and a pressing wheel 42; the covering plate 41 is fixedly arranged on the frame body 9, the covering plate 41 is located on the rear side of the pressing wheel 2, and the covering plate 41 is located on the outside of the V-shaped ditch, and is used to fill soil into the V-shaped ditch; the pressing wheel 42 is rotatably arranged on the frame body 9, the pressing wheel 42 is located on the rear side of the covering plate 41, and the pressing wheel 42 matches the position of the V-shaped ditch, and is used to compact the soil in the V-shaped ditch.

[0028] When the tractor drives the frame body 9 forward, a pair of furrow openers plows a V-shaped ditch with a radial cross-section on both sides of the crop planting strip. At the same time, a pair of pressing wheels 2 located at the rear side of the furrow opener presses the side of the ground film 941 downward to the inside of the V-shaped ditch. As the pressing wheel 2 rolls, the blade portion 31 of the piercing member 3 provided on the pressing wheel 2 breaks the side of the ground film 941, forming an incision on the ground film 941. At the same time, the air pump 7 is started to continuously input outside air into the water tank 5, increase the internal pressure of the water tank 5, and make the air at the top of the inner cavity of the water tank 5 flow into the inner cavity of the pressing wheel 2 through the air pipe 8. When the internal pressure of the pressing wheel 2 reaches a certain intensity, the internal gas of the pressing wheel 2 flows through the second guide cavity 612 and the safety valve 63 in turn to continuously discharge the pressing gas. The outside of the wheel 2 causes a certain degree of pressure in the inner cavity of the pressing wheel 2 to enhance the sealing effect between the piercing member 3 and the assembly hole 671 under the condition that there is no magnetic force. At the same time, the aqueous solution stored in the water tank 5 flows through the water pipe 62 and the first guide cavity 611 in sequence into the inner cavity of the pressing wheel 2. When the liquid level of the aqueous solution stored in the pressing wheel 2 reaches a certain height, the water level sensor sends a monitoring signal, and the electric control valve closes after receiving the monitoring signal, preventing the aqueous solution from flowing into the inner cavity of the pressing wheel 2 through the water pipe 62. When the liquid level of the aqueous solution stored in the pressing wheel 2 is lower than a certain height, the water level sensor sends a detection signal, and the electric control valve opens after receiving the monitoring signal, so that the aqueous solution stored in the water tank 5 can continue to flow through the water pipe 62 and the first guide cavity 611 in sequence into the inner cavity of the pressing wheel 2.

[0029] As the pressing wheel 2 rotates, when the magnetic metal part 675 moves to the bottom of the permanent magnet 66, the magnetic metal part 675 overcomes the elastic force of the supporting spring 673 under the magnetic force of the permanent magnet 66 and is adsorbed and fixed to the bottom of the permanent magnet 66. In this process, the magnetic metal part 675 drives the piercing member 3 to move upward through the movable bracket 674, thereby opening the assembly hole 671, so that a slit channel of a certain width is formed between the inner surface of the assembly hole 671 and the outer surface of the piercing member 3. After the assembly hole 671 is opened, the aqueous solution stored in the pressing wheel 2 is discharged through the piercing member 3 under the action of the air pressure in the inner cavity of the pressing wheel 2. 3 and the assembly hole 671, flushing the bottom of the piercing member 3, preventing the soil attached to the bottom of the piercing member 3 from being brought into the interior of the assembly hole 671 and attached to the inner surface of the assembly hole 671 during the upward displacement of the piercing member 3, so as to prevent the soil attached to the inner surface of the assembly hole 671 from adversely affecting the sealing between the piercing member 3 and the assembly hole 671 after the piercing member 3 is reset, and the aqueous solution flowing out through the slit channel between the piercing member 3 and the assembly hole 671 eventually falls into the V-shaped ditch, thereby increasing the humidity of the soil in the V-shaped ditch, thereby strengthening the soil in the V-shaped ditch. Secondly, in this embodiment, when the magnetic metal piece 675 is adsorbed and fixed to the bottom of the permanent magnet 66, the bottom of the piercing piece 3 still protrudes from the outer surface of the pressing wheel, so that it can still pierce the ground film to form an incision; as the pressing wheel 2 rotates further, the magnetic metal piece 675 is separated from the permanent magnet 66, and the magnetic force between the two is reduced. The piercing piece 3 slides downward again under the elastic force of the supporting spring 673 to reset, until the piercing piece 3 blocks the assembly hole 671 again, preventing the aqueous solution from flowing out through the slit channel between the piercing piece 3 and the assembly hole 671; in this embodiment, by pressing the pressing wheel 2, the magnetic metal piece 675 is separated from the permanent magnet 66, and the magnetic force between the two is reduced. Air is continuously introduced into the inner cavity of the pressing wheel 2 to maintain a certain degree of air pressure strength in the inner cavity of the pressing wheel 2, so as to enhance the sealing effect between the piercing member 3 and the assembly hole 671 under the condition that there is no magnetic force, and prevent the aqueous solution stored in the inner cavity of the pressing wheel 2 from leaking during the rolling process of the pressing wheel 2; and, when the piercing member 3 is subjected to the magnetic force and a narrow slit channel is formed between it and the inner wall of the assembly hole 671, the water flow ejected through the narrow slit channel has a certain intensity, so as to achieve a better flushing effect on the piercing member 3, and prevent the piercing member 3 from bringing the soil attached to its bottom into the assembly hole 671 during the retraction process.

[0030] Since the elastic force of the support spring 673 is greater than the elastic force of the return spring 653, when the magnetic metal part 675 stays at the position directly below the permanent magnet 66 for too long, as the gas entering the cavity between the piston 652 and the top wall of the inner cavity of the cylinder body 651 through the second one-way valve 655 increases, the piston 652 connected to the permanent magnet 66 through the connecting rod 656 is driven by the elastic force of the support spring 673 to overcome the elastic force of the return spring 653 and gradually move downward until the piercing part 3 blocks the assembly hole 671 to prevent the assembly hole 671 from being open for too long when the frame body 9 stops moving or moves too slowly, resulting in excessive outflow of the aqueous solution stored therein and reduced soil cohesion in the V-shaped ditch.

[0031] As the frame body 9 moves forward, the covering plate 41 located at the rear side of the pressing wheel 2 backfills the soil turned over by the furrowing plow 1 into the V-shaped ditch, so that it covers the upper side of the side of the ground film 941, and the pressing wheel 42 arranged at the rear side of the covering plate 41 rolls and presses the backfilled soil covering the upper side of the side of the ground film 941 as the frame body 9 moves forward, causing the soil on the upper side of the side of the ground film 941 to break through the incision opened on the side of the ground film 941 and combine with the soil on the lower side of the side of the ground film 941, and utilizes the cohesion between the soils to constrain the side of the ground film 941 to enhance the anchoring effect of the side of the ground film 941, prevent the ground film 941 from being blown away by strong winds, and ensure the survival rate of seeds and seedlings sown with the film.
