Description

[0002] Seeding is a very important link in agricultural production. The quality of the compaction effect during seeding operations directly affects the seeding quality. For different soil water contents, the required compaction intensity is different. If the compaction intensity is too small, the soil around the seeds will be too loose and moisture will be lost, affecting the germination of crop seeds. If the compaction intensity is too large, the soil will be too compact, affecting the emergence of seedlings. In addition, the amount of soil adhered to the compaction wheel and the size of the contact area with the soil both affect the rolling of the compaction wheel.

[0003] Ensuring that the compaction intensity is applied as required and the compaction wheel works efficiently is of great significance for improving seeding quality and achieving increased production and income of crops. However, in the existing technology, the compaction device only adjusts the compaction force in advance or replaces the corresponding compaction wheel according to the dry and wet conditions of the soil to be operated and the type of crop seeds before seeding operations, and the compaction force and compaction angle cannot be changed during the operation.

[0046] In order to enable those skilled in the art to better understand the present invention, the present invention will be further clearly and completely described below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0047] A typical embodiment of the present invention provides an intelligent compaction device, as Figure 2 shown, including a compaction support 56 and a rubber compaction wheel 57. On this basis, the intelligent compaction device further includes an optical sensor 51, an image acquisition device 52, a controller 53, a compaction pressure adjustment system 54, and a compaction angle adjustment system 55.

[0048] The optical sensor 51 is used to collect the water content of the soil flowing back into the seed furrow, and the image acquisition device 52 is used to collect the soil image after compaction. The optical sensor can adopt the Laender LD - TR04 type optical sensor.

The image acquisition device 52 is arranged at the upper rear part of the compaction support 56. The controller 53 is fixed on the single - body frame 33.

[0050] In this embodiment, the compaction pressure adjustment system 54 and the compaction angle adjustment system 55 are arranged inside the compaction bracket 56 to automatically adjust the compaction pressure and the compaction angle respectively. Rubber compaction wheels 57 are arranged on both sides of the compaction bracket 56 in a V shape, and the rubber compaction wheel sleeves for installing the rubber compaction wheels can rotate freely on the rubber compaction wheel shafts 58.

[0051] In this embodiment, as Figure 3 , Figure 4 shown, the compaction pressure adjustment system 54 includes a pressure adjustment motor 541, a first bevel gear 542, a second bevel gear 543, a lead screw 544, a guide sleeve 545, a first spring 546, a first coupling 547, a first shaft 548 and a guide sleeve fixing rod 549.

[0052] The pressure adjustment motor 541 is fixed to the upper rear of the compaction bracket 56. The pressure adjustment motor 541 is connected to the first shaft 548 through the first coupling 547. The first shaft 548 passes through the compaction bracket 56 and is connected to the first bevel gear 542 inside the compaction bracket 56. The second bevel gear 543 is vertically engaged with the first bevel gear 542. A thread is provided in the central hole of the second bevel gear 543. The second bevel gear 543 is threadedly connected to the lead screw 544. The lead screw 544 passes through the second bevel gear 543, then passes through the guide sleeve 545 and is connected to one end of the first spring 546 through a swivel sleeve 550. The swivel sleeve 550 includes a swivel sleeve body and a swivel sleeve shaft rotatably connected to the front end of the swivel sleeve body. Specifically, the first spring 546 is connected to the swivel sleeve shaft, and the front end of the lead screw 544 is connected to the swivel sleeve body after passing through the guide sleeve 545. The other end of the first spring 546 is connected to the rear end of the monomer frame 33. The guide sleeve 545 is fixed inside the compaction bracket 56 through the guide sleeve fixing rod 549.

[0053] In this embodiment, as Figure 5 , Figure 6 , Figure 7 shown, the compaction angle adjustment system 55 includes an angle adjustment motor 551, a motor fixing frame 552, a second coupling 553, a bushing 554, a second shaft 555, a rhombic swing frame 556, an arc-shaped slide rail 557 and an electromagnetic slider 558.

[0054] The angle adjustment motor 551 is fixed to the side of the compaction bracket 56 through the motor fixing frame 552. The angle adjustment motor 551 is connected to the second shaft 555 through the second coupling 553. The second shaft 555 is installed on the compaction bracket 56. A bushing 554 is arranged in the middle of the second shaft 555. The bushing 554 is fixedly installed on the second shaft 555 and rotates together with the second shaft 555. The bushing 554 is connected to the front end of the rhombic swing frame 556. The rear end of the rhombic swing frame 556 is connected to the electromagnetic slider 558.

[0055] An arc-shaped slide rail fixing plate 560 is installed on the pressing support 56, and the arc-shaped slide rail 557 is installed on the pressing support 56 through the arc-shaped slide rail fixing plate 560. The electromagnetic slider 558 is installed in the arc-shaped slide rail 557, and the electromagnetic slider 558 can move up and down along the arc-shaped slide rail 557 installed on the pressing support 56.

[0056] The left and right ends of the diamond-shaped swing frame 556 are connected to the rubber pressing wheels 57. Specifically, the rubber pressing wheels 57 are installed on the rubber pressing wheel shaft 58, and one end of the rubber pressing wheel shaft 58 is fixed to the diamond-shaped swing frame 556. The rubber pressing wheels 57 at both ends of the diamond-shaped swing frame 556 can change the angle relative to the ground as the diamond-shaped swing frame 556 rotates.

[0057] In a relatively specific embodiment, in the pressing angle adjustment system, fixing sleeves 559 are respectively arranged on both sides of the pressing support 56, and both ends of the second shaft 555 are rotatably installed in the fixing sleeves 559.

[0058] The controller 53 is respectively connected to the optical sensor 51, the image acquisition device 52, the pressure adjustment motor 541, and the angle adjustment motor 551. The controller 53 receives the signals obtained by the optical sensor 51 and the image acquisition device 52, and issues action instructions to the pressure adjustment motor 541 and the angle adjustment motor 551.

[0059] Both the above-mentioned pressure adjustment motor 541 and the angle adjustment motor 551 are servo motors.

[0060] Another typical embodiment of the present invention provides a seeding unit, as Figure 1 shown, which includes a four-bar linkage profiling mechanism 1, a seed metering system 2, a furrowing system 3, a depth-limiting and soil-covering system 4, and the intelligent pressing device 5 described above.

[0061] Among them, as Figure 8 shown, the four-bar linkage profiling mechanism 1 is arranged above the front of the seeding unit; the four-bar linkage profiling mechanism 1 includes an upper rod 11, a lower rod 12, a second spring 13, and a front plate 14.

[0062] The front plate 14 is bolted to the upper rod 11 and the lower rod 12 in front of the four-bar linkage profiling mechanism, and the front plate 14 can rotate freely between the upper rod 11 and the lower rod 12. The second spring 13 is arranged between the upper rod 11 and the lower rod 12 to apply pressure to the seeding unit. The other ends of the upper rod 11 and the lower rod 12 are bolted to the unit frame 33, and the unit frame 33 can rotate freely between the upper rod 11 and the lower rod 12.

[0063] Among them, as Figure 9 shown, the seed metering system 2 is arranged in the middle of the seeding unit. The seed metering system 2 includes a seed box 21, a seed metering device 22, and a seed guiding pipe 23.

[0064] The metering device 22 is fixedly installed on the seed box support by bolts. The seed box support is connected to the single unit frame 33. A seed box 21 is arranged above the metering device 22. The seed box 21 is connected to the seed box support at the side rear. The bottom of the metering device 22 is connected to the seed guiding pipe 23.

[0065] Among them, as Figure 10 shown, the ditching system 3 is arranged below the seeding single unit. The ditching system 3 includes a disc cutter 31, a cutter disc frame 32, a double disc ditching opener 34 and a first soil scraping plate 35.

[0066] The disc cutter 31 is arranged in front of the ditching system 3. The disc cutter 31 is installed on the single unit frame 33 through the cutter disc frame 32. The double disc ditching opener 34 is arranged below the single unit frame 33. The bottom of the seed guiding pipe 23 of the seeding system 2 is located inside the double disc ditching opener 34. The first soil scraping plate 35 is installed on the single unit frame 33 and is arranged outside the rear upper side of the double disc ditching opener 34.

[0067] Among them, as Figure 11 shown, the depth-limiting soil covering system 4 is arranged behind the double disc ditching opener 34. The depth-limiting soil covering system 4 includes a depth-limiting wheel 41, a wheel arm 42, a wheel shaft 43, a second soil scraping plate 44 and a seeding depth adjusting mechanism 45. The depth-limiting wheels 41 are respectively located at the outer rear positions of the double disc ditching opener 34. The depth-limiting wheels 41 are connected to the single unit frame 33 through the wheel arms 42. The second soil scraping plate 44 is installed on the single unit frame 33 and is arranged at the rear upper side of the depth-limiting wheels 41. The seeding depth adjusting mechanism 45 is arranged inside the rear of the single unit frame 33 and is used for adjusting the seeding depth.

[0068] Among them, the intelligent pressing device 5 is arranged behind the seeding single unit and is connected to the single unit frame 33 through a shaft 59.

[0069] When the seeding operation starts, the four-bar linkage profiling mechanism 1 pulls the single unit frame 33 to move forward. At the same time, the second spring 13 inside the four-bar linkage profiling mechanism 1 applies pressure to ensure that the seeding single unit always closely adheres to the soil surface. The disc cutter 31 draws a line on the cultivated land surface. The double disc ditching opener 34 cuts open the soil to form a seed furrow. Seeds are discharged one by one from the seed box 21 through the metering device 22 and fall into the formed seed furrow from the seed guiding pipe 23. The depth-limiting wheels 41 behind the double disc ditching opener 34 squeeze and cover the soil in the seed furrow. The seeding depth adjusting mechanism 45 controls the depth of the seed furrow. The rubber pressing wheel 57 of the intelligent pressing device 5 rotates around the shaft 59 under the action of the first spring 546 to complete the pressing work.

[0070] The optical sensor 51 measures the soil in the seed furrow squeezed and covered by the depth-limiting wheels 41 to obtain its moisture content. The optical sensor 51 transmits the moisture content information to the controller 53. The controller 53 issues an adjustment instruction to the pressure adjustment motor 541 and an adjustment instruction to the angle adjustment motor according to the change of the soil moisture content.

[0071] 1. Adjustment for compaction pressure

[0072] When the soil moisture content increases, the pressure regulating motor 541 rotates clockwise ( Figure 4 seen from above), driving the first bevel gear 542 to rotate clockwise. The first bevel gear 542 drives the second bevel gear 543 to rotate counterclockwise ( Figure 4 seen from the left). The second bevel gear 543 drives the screw rod 544 to move outward along the guide sleeve 545. Since the screw rod 544 is connected to the first spring 546 through the rotating sleeve 550, the screw rod 544 rotates and moves outward at the same time, causing the first spring 546 to only be stretched, increasing the compaction pressure and the compaction intensity of the rubber compaction wheel 57 on the soil.

[0073] When the soil moisture content decreases, the pressure regulating motor 541 rotates counterclockwise ( Figure 4 seen from above), driving the first bevel gear 542 to rotate counterclockwise. The first bevel gear 542 drives the second bevel gear 543 to rotate clockwise ( Figure 4 seen from the left). The second bevel gear 543 drives the screw rod 544 to move inward along the guide sleeve 545, causing the first spring 546 to retract, reducing the compaction pressure and the compaction intensity of the rubber compaction wheel 57 on the soil.

[0074] 2. Adjustment for compaction angle

[0075] When the soil moisture content increases, the angle regulating motor 551 rotates counterclockwise and drives the second shaft 555 to rotate through the second coupling 553. The second shaft 555 drives the diamond-shaped crank frame 556 to rotate upward with the sleeve 554 as the center through the sleeve 554. At the same time, the other end of the diamond-shaped crank frame 556 moves upward along the arc-shaped slide rail 557. The two rubber compaction wheels 57 at the left and right ends of the diamond-shaped crank frame 556 rotate eccentrically upward with the sleeve 554 as the rotation center. The two rubber compaction wheels 57 roll along the soil surface. Since the V-shaped angle formed by the two rubber compaction wheels 57 is from large to small from directly above to directly in front (the forward direction), taking the middle position between directly above and directly in front as the starting position, directly above as the position when the V-shaped angle is adjusted to the maximum, and directly in front as the position when the V-shaped angle is adjusted to the minimum. When the rubber compaction wheels 57 rotate eccentrically upward, the position of the highest point of the rubber compaction wheels 57 relative to the ground changes, and the V-shaped angle relative to the ground also changes accordingly. When the rubber compaction wheels 57 rotate eccentrically upward, the highest point of the rubber compaction wheels 57 before rotation is offset forward and downward relative to the highest point after rotation. Relative to the ground, the V-shaped angle of the highest point of the rubber compaction wheels 57 becomes larger. Therefore, the contact area between the rubber compaction wheels 57 and the soil decreases, and the soil adhesion decreases, enabling the rubber compaction wheels 57 to work properly.

[0076] Conversely, when the soil moisture content decreases, the angle adjustment motor 551 rotates clockwise, drives the second shaft 555 to rotate through the second coupling 553. The second shaft 555 drives the rhombic crank frame 556 to rotate downward with the bushing 554 as the center. The other end of the rhombic crank frame 556 moves downward along the arc-shaped slide rail 557. The two rubber pressing wheels 57 at the left and right ends of the rhombic crank frame 556 rotate eccentrically downward with the bushing 554 as the rotation center. Relative to the ground, the V-shaped angle at the highest point of the rubber pressing wheel 57 becomes smaller, increasing the contact area with the soil and achieving a better pressing effect.

[0077] When the soil moisture content is stable, the electromagnetic slider 558 is energized to generate an electromagnetic force, adsorbs the arc-shaped slide rail 557, locks the position, and keeps the angle of the pressing wheel unchanged.

[0078] The image acquisition device 52 collects the real-time compaction condition of the soil after pressing and feeds the collected image back to the controller 53. The controller 53 analyzes the fed-back image. If it is determined that the pressing device fails, an alarm prompt is issued.

[0079] The scope of protection claimed by the present invention is not limited to the above specific embodiments. For those skilled in the art, the present invention can have various deformations and modifications. Any modification, improvement, and equivalent replacement made within the concept and principle of the present invention should be included within the protection scope of the present invention.
