Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to an intelligent wheat press with adjustable pressure. Background Technology

[0002] To address the issue of soil asymmetry after wheat sowing, which hinders moisture retention and frost resistance, unmanned rolling operations are necessary after sowing and during the overwintering period. Traditional rolling operations involve manually driving small tractors to pull rollers or increasing the number of tractor tires to widen the rolling area. These methods suffer from poor row alignment accuracy, leading to missed or excessive compaction, and low efficiency. Furthermore, they cannot adjust the rolling pressure according to soil conditions. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that when using the existing compaction machine for compaction operations, it is impossible to adjust the compaction pressure according to the soil conditions.

[0004] To address the aforementioned technical problems, this invention provides an intelligent wheat pressing machine with adjustable pressure. It does not require tractor traction, but drives the rear pressing roller to move forward automatically, which in turn drives the front pressing roller to roll forward. The front and rear pressing rollers perform pressing operations simultaneously, resulting in a wide pressing width and improved work efficiency. At the same time, the pressing pressure is adjustable.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wheat intelligent press with adjustable pressure, comprising,

[0006] The main component includes a frame, with a steering bracket connected to the front end of the frame and a rear axle bracket fixedly connected to the rear end of the frame.

[0007] The pressing assembly includes a rear axle connected to a rear axle bracket, the left and right ends of the rear axle being power output ends, and the left and right ends of the rear axle being respectively connected to rear pressing rollers. The lower part of the steering bracket is rotatably connected to a front pressing roller, and the left and right ends of the front pressing roller cover the gap between the two rear pressing rollers.

[0008] The post-press pressure regulating assembly includes several rear counterweights detachably connected to the post-press roller;

[0009] The front press pressure regulating assembly includes several front counterweights that are detachably connected to the front press roller.

[0010] The frame is equipped with a Beidou navigation system, and a steering motor is fixedly connected to the front end of the frame. The Beidou navigation system and the steering motor are electrically connected. The steering motor is connected to the steering bracket via a steering system. The steering system is existing technology and not an improvement in this application, so it will not be described in detail. The pressing path is planned through the Beidou navigation system. The rear axle in this application is a drive axle, which is existing technology. A power motor is fixedly connected to the housing of the rear axle, and the power motor is the power source for driving the rear pressing rollers to rotate. The two rear pressing rollers are positioned to the left and right of the front pressing rollers in the left-right direction to avoid missed pressing. Before operation, the pressing is adjusted according to the farmland soil. The pressure is adjusted by installing corresponding front and rear counterweights inside the front and rear pressing rollers. During operation, the power motor, Beidou navigation system, and steering motor are activated. The power motor drives the rear pressing roller to rotate via the rear axle. The simultaneous rotation of the two rear pressing rollers propels the entire pressing machine forward. The Beidou navigation system controls the steering motor, which in turn drives the steering bracket to steer. The steering bracket then steers the front pressing roller. The Beidou navigation system guides the pressing machine to follow a set pressing path, improving pressing efficiency. This method can be applied to pressing operations in wheat planting.

[0046] Example 2

[0047] Reference Figure 2 , Figure 3 , Figures 7-11 and Figures 15-17 This is the second embodiment of the present invention, which provides a wheat intelligent press with adjustable pressure, which facilitates pressure adjustment on the front press roller 201 and the rear press roller 202.

[0048] In this embodiment, a front counterweight 306 is connected to the front pressing rollers 201 on both sides of the front partition 201c, and a rear counterweight 411 is connected to the rear pressing rollers 202 on both sides of the rear partition 202c. Several first rear fixing blocks 202b are arranged on the side of the rear partition 202c away from the rear axle 105. Each first rear fixing block 202b has a first rear receiving opening on the side away from the rear partition 202c. A first rear clamping claw 401 and a second rear clamping claw 403 are rotatably connected to the first rear fixing block 202b at the first rear receiving opening, capable of simultaneously pressing the rear counterweight 411 onto the first rear fixing block 202b. In the radial direction, the first rear clamping claw 401 is located between the center of the second rear clamping claw 403 and the center of the rear partition 202c. A first rear transmission block 408 that can move axially is slidably connected inside the first rear fixing block 202b. At least one first rear spring 409 is fixed between the first rear clamping jaws 401 and 403 on opposite sides of one end of the first rear receiving port. In the axial direction, the first rear spring 409 is located between the first rear transmission block 408 and the rear partition 202c. The first rear transmission block 408, in the radial direction, has a first rear inclined surface 408b that is inclined axially from the outside inwards towards the center of the first rear transmission block 408 on one side of each of the first and second rear clamping jaws 401 and 403, respectively. Initially, the first and second rear clamping jaws 401 and 403, at one end within the first rear receiving port and on opposite sides, are inclined towards the two first rear inclined surfaces 408b under the action of the first rear spring 409. The outward-facing ends of the first and second rear clamping jaws 401 and 403 (the ends furthest from the rear partition 202c) are open (e.g., ...). Figure 9 As shown), when the first rear drive block 408 moves toward the direction of the rear partition 202c, the side of the first rear drive block 408 away from the rear partition 202c in the axial direction gradually moves away from the rotation center of the first rear clamping jaw 401 and the second rear clamping jaw 403. The side of the first rear drive block 408 away from the rear partition 202c pushes against the first rear clamping jaw 401 and the second rear clamping jaw 403 and opens at one end of the first rear receiving port, so that the side of the first rear clamping jaw 401 and the second rear clamping jaw 403 away from the rear partition 202c gradually closes.

[0049] Specifically, a plurality of second rear fixing blocks 202e are arranged on the side of the rear partition 202c opposite to the rear axle 105. The side of each second rear fixing block 202e away from the rear partition 202c has a second rear receiving opening 202e-1. A third rear clamping claw 417 and a fourth rear clamping claw 416, capable of simultaneously pressing the rear counterweight 411 onto the second rear fixing block 202e, are rotatably connected to the second rear fixing block 202e at the second rear receiving opening 202e-1. In the radial direction, the third rear clamping claw 417 is located between the fourth rear clamping claw 416 and the center of the rear partition 202c. A second rear transmission block, capable of axial sliding, is slidably connected within the second rear fixing block 202e. At least one second rear spring is fixed to one end of the third rear clamping claw 417 and the fourth rear clamping claw 416, which are positioned opposite each other. The second rear spring is located between the second rear transmission block and the rear partition 202c. The rear drive block has a second rear inclined surface that is inclined from the outside to the center of the second rear drive block in the axial direction on one side of the second rear clamping jaw 403 and the other side of the second rear clamping jaw 403, respectively. In the initial state, the third rear clamping jaw 417 and the fourth rear clamping jaw 416 are located at one end of the second fixed block and are respectively inclined in the direction of the two second rear inclined surfaces under the action of the second rear spring. The third rear clamping jaw 417 and the fourth rear clamping jaw 416 are open. When the second rear drive block moves in the direction of the rear partition 202c, the side of the second rear drive block away from the rear partition 202c in the axial direction gradually moves away from the rotation center of the third rear clamping jaw 417 and the fourth rear clamping jaw 416, and the side of the third rear clamping jaw 417 and the fourth rear clamping jaw 416 away from the rear partition 202c gradually closes.

[0050] The first rear drive block 408, the second rear drive block, and the front drive block 309 have the same structure. The first rear fixed block 202b and the second rear fixed block 202e have the same structure. The inner ends of the first rear fixed block 202b and the second rear fixed block 202e are both fixedly connected to slide rails 410 parallel to the central axis of the rear pressing roller 202. The first rear drive block 408 has a slide groove 408a that corresponds one-to-one with the slide rail 410. The first rear drive block 408 is slidably connected to the slide rail 410 through the slide groove 408a.

[0051] When the moving rod drives each transmission block to move horizontally, each transmission block slides horizontally along the corresponding slide rail 410, improving the reliability of the transmission block movement.

[0052] In the initial state, the first rear clamping jaw 401 and the second rear clamping jaw 403 are open at one end outside the first rear fixing block 202b, and the third rear clamping jaw 417 and the fourth rear clamping jaw 416 are open at one end outside the second rear fixing block 202e. When adjusting the pressing pressure, the four corresponding weight rear counterweights 411 are inserted into the two rear pressing rollers 202 in pairs. Taking the pressing pressure adjustment of one rear pressing roller 202 as an example, a first counterweight 411a and a second counterweight 411b are inserted horizontally into the rear pressing roller 202 below the rear fixing plate 202a in sequence. The first counterweight 411a and the second counterweight 411b are connected together, and the ring 411c is aligned with each open first rear clamping jaw 401 and the second rear clamping jaw 403. When the rear counterweights are adjusted, the pressing pressure is adjusted. When the counterweight 411 enters the rear mounting opening 202d inside the rear fixing plate 202a, align the counterweight 411 so that each ring 411c is inserted into each of the open first rear clamping jaws 401 and second rear clamping jaws 403. Then, insert another first counterweight 411a and another second counterweight 411b horizontally into the rear pressure roller 202 below the rear axle 105. The first counterweight 411a and second counterweight 411b are joined together, and the rings 411c are aligned with each of the open first rear clamping jaws 401 and second rear clamping jaws 403. Each ring 411c is inserted between the third rear clamping jaw 417 and the fourth rear clamping jaw 416. The two rear counterweights 411 respectively abut against the first rear fixing block 202b and the second rear fixing block 202e. Use a tool set 500 (e.g., Figure 18 As shown, the tool sleeve 500 has insertion holes 501 corresponding to the two handles 411e. The tool sleeve 500 can be sleeved onto the two handles 411e through the insertion holes 501, covering two of the handles 411e and pressing down on the rear counterweight 411 to stabilize the rear counterweight 411. This causes the first rear transmission block 408 and the second rear transmission block to move towards the direction of the rear partition 202c. The inner ends of the first rear clamping jaws 401 and the second rear clamping jaws 403 gradually open, and the first rear clamping jaws 401 and the second rear clamping jaws 403 rotate. The first rear clamping jaws 401 and the second rear clamping jaws 403 are outside the first rear fixing block 202b. One end gradually closes and rotates in the direction of the corresponding ring 411c. The first rear transmission block 408 stops moving. At the same time, the inner ends of the third rear clamping jaw 417 and the fourth rear clamping jaw 416 gradually open. The third rear clamping jaw 417 and the fourth rear clamping jaw 416 rotate.

[0057] Reference Figures 2 to 18 This is the third embodiment of the present invention, which provides a wheat intelligent pressing machine with adjustable pressure, which can further facilitate the adjustment of the pressing pressure of each pressing roller.

[0058] Specifically, the rear pressing pressure regulating assembly 400 also includes a first rear moving block 404 and a second rear moving block 414 that can move left and right along the central axis of the rear pressing roller 202. The power output end is rotatably connected inside the second rear moving block 414. The first rear moving block 404 and the second rear moving block 414 are respectively located on both sides of the rear partition 202c in the axial direction. The first rear moving block 404 and the second rear moving block 414 move towards each other or away from each other in the left and right direction. A plurality of first rear moving rods 402 are arranged on the outer edge of the first rear moving block 404. The first rear clamping jaw 401 has a first movable groove 401a that allows the first rear moving rods 402 to move axially.

The second rear fixed block 202e has a second rear sliding groove 202e-2 that allows the second rear moving rod 415 to slide left and right. The end of the second rear moving rod 415 away from the second rear moving block 414 passes through the second rear sliding groove 202e-2 and the second movable groove 417a in sequence and is fixedly connected to the second rear transmission block.

[0059] The rear counterweight 411 has several rings 411c arranged on it, each corresponding to a second rear fixing block 202e. The first rear clamping claw 401 and the second rear clamping claw 403 can press the rings 411c. The rear counterweight 411 includes a first counterweight part 411a and a second counterweight part 411b. When the first counterweight part 411a and the second counterweight part 411b are placed vertically, they can fit together. The first counterweight part 411a has insertion slots on both sides of its end in the radial direction. The second counterweight part 411b has insertion protrusions 411b-1 on both sides of its end in the radial direction, which correspond to the insertion slots. The second counterweight part 411b can be inserted into the insertion slots through the insertion protrusions 411b-1. In this embodiment, the schematic diagram of the counterweight is a whole ring 411c, that is, the first counterweight part 411a and the second counterweight part 411b inserted together are combined to form the whole ring 411c (e.g., Figure 15 (As shown), but not limited to this method, the shape of the rear counterweight 411 between adjacent rings 411c can be configured according to the required weight. It is sufficient that the center of the rear counterweight 411 has a through-hole 411d to avoid the corresponding rear moving rod and the corresponding rear moving block, as shown. Figure 16As shown in the rear counterweight 411 (used at the first rear moving block 404), a handle 411e for easy hand gripping can also be provided on the rear counterweight 411 between the rings 411c; the structure of the rear counterweight for passing through the second rear moving block 414 is configured according to the shape of the second rear moving block 414, and will not be shown in this application.

[0060] Specifically, a rear drive screw 412 is rotatably connected between the rear fixed plate 202a and the rear partition 202c. The end of the rear drive screw 412 away from the rear axle 105 is rotatably connected to the corresponding rear rotating shaft 107. The rear drive screw 412 is threadedly connected to the first rear moving block 404. A transmission screw 406 rotatably connected to the rear partition 202c is threadedly connected to the second rear moving block 414. The rear partition 202c has a mounting groove 20 on the side opposite to the first rear moving block 404. 2c-1, A drive gear 405 is fixedly connected to the rear drive screw 412 at the installation sink 202c-1. The end of the transmission screw 406 away from the second rear moving block 414 is connected to a driven gear 407 that cooperates with the drive gear 405. The first rear moving block 404 and the second rear moving block 414 move in opposite directions. Rear counterweight motors 413 are fixedly connected to the left and right sides of the frame 101 respectively. The rear counterweight motors 413 are connected to the corresponding rear drive screws 412.

[0061] When the rear counterweight 411 is stabilized by the tool sleeve 500, the rear counterweight motor 413 is activated, the rear drive screw 412 rotates, the rear drive screw 412 drives the drive gear 405 to rotate and the first moving block to move. The drive gear 405 drives the driven gear 407 to rotate, the driven gear 407 drives the transmission screw 406 to rotate, the transmission screw 406 drives the second moving block to move. The first moving block drives the first rear transmission block 408 to move via the first moving rod, and the second moving block drives the second rear transmission block to move via the second moving rod. The direction of action of the rear counterweight motor 413 is controlled so that the first rear transmission block 408 and the second rear transmission block slide towards the direction of the rear partition 202c respectively. When each gripper presses the rear counterweight 411 onto the corresponding rear fixed block, the rear counterweight motor 413 stops operating, thereby further realizing the adjustment of the pressing pressure of the rear pressing roller 202, making pressure adjustment more convenient.

[0062] Specifically, the front pressurization pressure regulating assembly 300 also includes a front drive screw 302 rotatably connected to two front rotating shafts 108. Front moving blocks 303 are threadedly connected to the front drive screws 302 on both sides of the front partition 201c. The two front moving blocks 303 move towards each other or away from each other. Each front moving block 303 is threadedly connected to the front drive screw 302. Several front moving rods 304, corresponding one-to-one with the front fixed blocks 201b, are arranged on the front moving blocks 303. A front sliding groove 201b-1 is opened at one end of the front moving block 303. The front moving rod 304 is slidably connected to the front fixed block 201b via the front sliding groove 201b-1. A front movable groove 305a is opened on the first front clamping claw 305. The front moving rod 304 passes through the front movable groove 305a and is connected to the front transmission block 309. A front counterweight motor 301 is fixedly connected to one side of the steering bracket 103 in the left-right direction. The front counterweight motor 301 is connected to the front drive screw 302.

[0063] When the front counterweight 306 is stabilized by the tool sleeve 500, the front counterweight motor 301 is activated, the front drive screw 302 rotates, and the front drive screw 302 drives the two front moving blocks 303 to move. The front moving blocks 303 drive the front transmission blocks 309 to move via the corresponding front moving rods 304, controlling the direction of the front counterweight motor 301 so that the two front transmission blocks 309 move simultaneously toward the direction of the front partition 201c. When each front clamping jaw presses the front counterweight 306 onto the corresponding front fixed block 201b, the front counterweight motor 301 stops operating, thereby further realizing the adjustment of the pressing pressure of the front pressing roller 201, making pressure adjustment more convenient.

[0064] Example 4

[0065] Referring to the figure, this is the fourth embodiment of the present invention, which provides a wheat intelligent press with adjustable pressure, which can further improve the reliability of the horizontal movement of each moving block.

The rear guide sleeve 402a can slide along the outer edge of the corresponding rear guide rod 415a. Several rear guide holes corresponding to the rear guide sleeve 402a are arranged on the rear partition 202c, and the rear guide sleeve 402a is slidably connected to the rear partition 202c through the corresponding rear guide holes. Two front moving rods 304 are respectively fixed to one side of the front partition 201c with front guide sleeves and front guide rods. The front guide sleeves can slide along the outer edge of the corresponding front guide rods. Several front guide holes corresponding to the front guide sleeves are arranged on the front partition 201c, and the front guide sleeves can slide along the corresponding front guide holes to the front partition 201c.

[0067] When the first rear moving block 404 and the second rear moving block 414 move, the rear guide sleeve 402a slides along the rear partition 202c, and at the same time, the rear guide rod 415a slides along the corresponding rear guide sleeve 402a, further restricting the rotation of the first rear moving block 404 and the second rear moving block 414, and improving the reliability of the horizontal movement of the first rear moving rod 402 and the second rear moving rod 415; when the two front moving blocks 303 move in opposite directions or towards each other, the front guide sleeve slides along the front partition 201c, and at the same time, the front guide rod slides along the corresponding front guide sleeve, further restricting the rotation of the two front moving blocks 303, and improving the reliability of the horizontal movement of the two front moving rods 304.
