Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an agricultural tillage and soil-turning machine. Background Technology

[0002] Agricultural tillage machinery, commonly known as tillers or tractors, is a type of mechanical equipment widely used in agricultural production. It is primarily used for cultivating land and loosening the soil to provide a more suitable soil environment for crop cultivation. Through mechanical force, it loosens the soil, promotes soil aeration, improves soil structure, eliminates weeds, and enhances the soil's water and fertilizer retention capacity.

[0003] Chinese patent CN117859420B, authorized and published on May 3, 2024, discloses a soil-turning machine for agricultural tillage. It includes side plates and an arc-shaped plate mounted on the side plates. A transverse rotating shaft is rotatably mounted on the side plates. A radial insertion mechanism rotates synchronously with the transverse rotating shaft to turn the soil. A connecting mechanism is disposed within the radial insertion mechanism to fix its movable end. A circulating covering mechanism passes through one side plate and abuts against the radial insertion mechanism, facilitating adjustment of its working position along the transverse rotating shaft axially during the soil-turning process. In the aforementioned application, a soil-turning blade mounted on a drive shaft is used for the turning operation. However, when increasing the drive shaft speed to improve turning efficiency, the stability of the soil-turning blade mounted on the drive shaft becomes poor, affecting the turning effect of the device. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an agricultural tillage and soil-turning machine, solving the problems mentioned in the background section. To achieve the above objectives, this invention is implemented through the following technical solution: an agricultural tillage and soil-turning machine, comprising a fixed plate and tilling blades, wherein a power shaft driven by a motor is rotatably connected inside the fixed plate, a mounting base is fixedly connected to the outside of the power shaft, and a mounting cylinder is fixedly connected to the outside of the mounting base;

[0005] A hydraulic chamber one is driven to the outer side of the power shaft. The inner wall of the hydraulic chamber one is connected to a movable block via an elastic telescopic plate. An arc-shaped rod is slidably connected to the side of the hydraulic chamber one. A second hydraulic chamber is fixedly connected to the outer side of the mounting base. A force-bearing rod is slidably connected to one end of the second hydraulic chamber, and a transmission rod is slidably connected to the other end. A spring one is fixedly connected to the side of the force-bearing rod, and a limiting block is connected to the side of the transmission rod via a spring two. Limiting grooves are provided on both sides of the turning blade. The interior of the fixed plate is equipped with a replacement assembly for changing the turning blade and a buffer assembly for maintaining stability. This improves turning efficiency while maintaining the stability of the turning blade during use, thereby enhancing the turning effect of the device in this situation.

[0006] Preferably, the force-bearing rod is located on the side of the arc-shaped rod and is in contact with the arc-shaped rod.

[0007] Preferably, the mounting cylinder has a through opening, the cross-sectional shape of which is adapted to the transmission rod and the limiting block.

[0008] Preferably, the replacement component includes a hydraulic chamber three, with a baffle rotatably connected inside the hydraulic chamber three. An elastic telescopic plate two is fitted to the side of the baffle. A connecting rod is slidably connected to the side of the hydraulic chamber three away from the hydraulic chamber two. A torsion spring block is rotatably connected to the side of the connecting rod. A force-bearing block is fixedly connected to the outer side of the torsion spring block. A pressing block is fixedly connected to the inner wall of the fixing plate. This allows for quick removal of the soil-turning blades from the device, improving the device's efficiency.

[0009] Preferably, the hydraulic chamber three is located on the side of the hydraulic chamber two, and is fixedly connected to and communicates with the hydraulic chamber two.

[0010] Preferably, each group of elastic telescopic plates has two plates, and the two elastic telescopic plates are symmetrically distributed about the baffle.

[0011] Preferably, the buffer assembly includes a hydraulic device communicating with the hydraulic chamber two. A push rod is slidably connected to the top of the hydraulic device, and a buffer chamber is slidably connected to the inner wall side of the fixed plate. A buffer rod is connected to the bottom of the inner wall of the buffer chamber via a spring three. A force-bearing plate is fixedly connected to the top of the buffer rod, and buffer rubber blocks are fitted to the inner wall side of the buffer chamber. This provides additional buffering for the rapidly rotating power shaft, further improving the stability of the device during use.

[0012] Preferably, the buffer chamber is located at the top of the push rod and is fixed to the push rod.

[0013] This invention provides an agricultural tillage and soil-turning machine. It has the following beneficial effects:

[0014] (1) This agricultural tillage tillage machine, when the speed of the power shaft is increased, can be combined with hydraulic chamber 1, elastic telescopic plate 1, movable block, arc rod, hydraulic chamber 2, force rod, transmission rod, spring 1, spring 2, limiting block and limiting groove to improve tillage efficiency while maintaining the stability of the tillage plate during use, thereby improving the tillage effect of the device under this condition.

[0015] (2) When the soil turning machine needs to clean the soil turning blades on the device, start the power shaft and rotate it clockwise by a certain angle. With the help of the hydraulic chamber three, baffle, elastic telescopic plate two, connecting rod, torsion spring block, force block and extrusion block, the soil turning blades on the device can be quickly removed, which improves the efficiency of the device.

[0016] (3) When the power shaft rotates rapidly, causing the pressure inside the hydraulic chamber to increase, the agricultural tillage and soil turning machine can perform additional buffering operation on the rapidly rotating power shaft by cooperating with the hydraulic device, push rod, buffer chamber, spring three, buffer rod, force plate and buffer rubber block, which further improves the stability of the device during use.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0031] Please see Figures 1-5 An agricultural tillage and soil turning machine includes a fixed plate 100 and a tilling blade 200. The fixed plate 100 is rotatably connected to a power shaft 300 driven by a motor. The power shaft 300 is fixedly connected to a mounting base 400 on the outside. The mounting base 400 is fixedly connected to a mounting cylinder 500 on the outside.

[0032] A hydraulic chamber 601 is connected to the outer side of the power shaft 300. A movable block 603 is connected to the inner wall of the hydraulic chamber 601 via an elastic telescopic plate 602. An arc-shaped rod 604 is slidably connected to the side of the hydraulic chamber 601. To improve soil turning efficiency and thus increase the rotational speed of the power shaft 300, [further details are needed]. Figure 3 From a medium perspective, rapidly rotating the power shaft 300 counterclockwise will synchronously drive the hydraulic chamber 601 connected to it to rotate rapidly. This causes the movable block 603 inside the hydraulic chamber 601 to stretch the elastic telescopic plate 602 under the action of centrifugal force and slide along the inner wall of the hydraulic chamber 601. This increases the pressure inside the hydraulic chamber 601, which is slidably connected to the movable block 603, and drives the arc-shaped rod 604, which is slidably connected to the hydraulic chamber 601, to move.

[0033] A hydraulic chamber 2 605 is fixedly connected to the outer side of the mounting base 400. A force-bearing rod 606 is slidably connected to one end of the hydraulic chamber 2 605. The force-bearing rod 606 is located on the side of the arc-shaped rod 604 and is in contact with the arc-shaped rod 604. A transmission rod 607 is slidably connected to the other end of the hydraulic chamber 2 605. A spring 1 608 is fixedly connected to the side of the force-bearing rod 606. A limiting block 610 is connected to the side of the transmission rod 607 through a spring 2 609. A through opening is provided on the mounting cylinder 500. The cross-sectional shape of the opening is adapted to the transmission rod 607 and the limiting block 610. Limiting grooves 611 are provided on both sides of the soil turning blade 200. As the hydraulic chamber 601 rotates, the arc-shaped rod 604 extends synchronously, compressing the force-bearing rod 606. This causes the force-bearing rod 606 to move to both sides. In conjunction with the hydraulic chamber 605, which is slidably connected to the force-bearing rod 606, the pressure within the hydraulic chamber 605 increases. This drives the transmission rod 607, which is slidably connected to the hydraulic chamber 605, to move. The transmission rod 607, through the spring 609, applies a certain force to the limiting block 610, causing the limiting block 610 to move further into the limiting groove 611 on the soil-turning blade 200. This improves soil-turning efficiency while maintaining the stability of the soil-turning blade 200 during use, thereby enhancing the soil-turning effect of the device in this configuration.

[0034] When the speed of the power shaft 300 slows down or stops, the movable block 603 loses the traction of centrifugal force and can be reset under the action of the elastic telescopic plate 602. Similarly, the arc rod 604 is reset, so that the force rod 606 is unrestricted and is reset under the action of the spring 608. Similarly, the transmission rod 607 is reset. In this way, the device can be restored to its initial state for the next use of the device.

[0035] When the soil-turning blade 200 is installed on the drive shaft 300, the soil-turning blade 200 moves into the mounting cylinder 500. The bottom part of the soil-turning blade 200 first presses against the limiting block 610, causing the limiting block 610 to press against the second spring 609 and move towards the transmission rod 607. When the limiting groove 611 on the soil-turning blade 200 moves to the limiting block 610 as the soil-turning blade 200 moves, the limiting block 610 loses its restraint and resets under the action of the second spring 609, thus locking into the limiting groove 611, completing the installation of the soil-turning blade 200 and making the device easier to use. The fixed plate 100 is equipped with a replacement assembly 700 for replacing the soil-turning blade 200 and a buffer assembly 800 for maintaining stability.

[0036] In order to improve soil turning efficiency, and thus increase the power shaft speed by 300, during use, Figure 3From a medium perspective, rapidly rotating the power shaft 300 counterclockwise will synchronously drive the hydraulic chamber 601 connected to it to rotate rapidly. This causes the movable block 603 inside the hydraulic chamber 601 to stretch the elastic telescopic plate 602 under centrifugal force and slide along the inner wall of the hydraulic chamber 601. This increases the pressure inside the hydraulic chamber 601, which is slidably connected to the movable block 603, causing the arc-shaped rod 604, also slidably connected to the hydraulic chamber 601, to move. Simultaneously, the arc-shaped rod 604, rotating with the hydraulic chamber 601, extends and compresses the force-bearing rod 606, causing it to move to both sides. This, in conjunction with the hydraulic chamber 605, which is slidably connected to the force-bearing rod 606, increases the pressure inside the hydraulic chamber 605, causing the transmission rod 607, slidably connected to the hydraulic chamber 605, to move. The transmission rod 607, through the spring 609, applies a certain force to the limiting block 610, causing the limiting block 610 to further move into the limiting groove 6 on the soil-turning blade 200. 11. Movement within the shaft: When the speed of the power shaft 300 slows down or stops, the movable block 603 loses the traction of centrifugal force and can be reset under the action of the elastic telescopic plate 602. Similarly, the arc rod 604 is reset, causing the force rod 606 to lose its restriction and be reset under the action of the spring 608. Similarly, the transmission rod 607 is reset, thus restoring the device to its initial state. When the soil turning plate 200 is installed on the power shaft 300, the soil turning plate 200 moves into the mounting cylinder 500. The bottom part of the soil turning plate 200 first presses the limiting block 610, causing the limiting block 610 to press the spring 609 and move towards the transmission rod 607. When the limiting groove 611 on the soil turning plate 200 moves to the limiting block 610 as the soil turning plate 200 moves, the limiting block 610 loses its restriction and is reset under the action of the spring 609, thus locking into the limiting groove 611, completing the installation of the soil turning plate 200. Example

[0037] Please see Figures 1-7 Based on Embodiment 1, the replacement component 700 includes a third hydraulic chamber 701, which is located to the side of the second hydraulic chamber 605 and is fixedly connected to and communicates with the second hydraulic chamber 605. A baffle 702 is rotatably connected inside the third hydraulic chamber 701. Two elastic telescopic plates 703 are mounted on the side of the baffle 702, with each group having two plates symmetrically distributed about the baffle 702. A connecting rod 704 is slidably connected to the side of the third hydraulic chamber 701 away from the second hydraulic chamber 605. A torsion spring block 705 is rotatably connected to the side of the connecting rod 704, and a force-bearing block 706 is fixedly connected to the outer side of the torsion spring block 705. When it is necessary to remove and clean the soil-turning blade 200 on the device, Figure 6From a medium perspective, the power shaft 300 is started and rotated clockwise by a certain angle. At this time, the hydraulic chamber 3 701, which is fixed to the hydraulic chamber 2 605, drives the force-bearing block 706 to rotate clockwise synchronously. A pressing block 707 is fixedly connected to the inner wall of the fixing plate 100. When the force-bearing block 706 rotates clockwise, it is pressed by the pressing block 707. Because the end of the force-bearing block 706 away from the torsion spring block 705 is restricted by the connecting rod 704, the force-bearing block 706 cannot rotate around the torsion spring block 705 as its axis. Thus, the connecting rod 704 moves relative to the hydraulic chamber 3 701 under the action of the force-bearing block 706 and the pressing block 707. At this time, the connecting rod 704 moves away from the hydraulic chamber 3 701, reducing the pressure inside the hydraulic chamber 3 701. The baffle 702 inside hydraulic chamber 3 701 then compresses the elastic telescopic plate 703 near the connecting rod 704, causing it to rotate. The connecting rod 704 continues to move, simultaneously reducing the pressure in hydraulic chamber 2 605, which is connected to hydraulic chamber 3 701. This causes the transmission rod 607 to move, allowing it to move via spring 2 609, which in turn moves the limiting block 610 out of the limiting groove 611. This removes the restriction between the mounting cylinder 500 and the soil-turning blade 200, allowing the soil-turning blade 200 to move out of the mounting cylinder 500 under gravity. This allows for quick removal of the soil-turning blade 200 from the device, improving its efficiency.

[0038] When the device is performing the soil turning operation normally, Figure 6 From a medium perspective, the clockwise rotating power shaft 300 drives the hydraulic chamber 701 and the force-bearing block 706 to rotate counterclockwise. At this time, when the force-bearing block 706 rotates to the state of contact with the extrusion block 707, the force-bearing block 706 is not restricted by the connecting rod 704, so that the force-bearing block 706 drives the torsion spring block 705 fixedly connected to it to rotate. In this way, when the force-bearing block 706 rotates counterclockwise to the extrusion block 707, it avoids the extrusion block 707 under the action of the torsion spring block 705, maintaining the normal use of the device. While improving the efficiency of the device, it will not have any additional impact on the soil turning operation of the device.

[0039] In use, based on Embodiment 1, when it is necessary to remove and clean the soil-turning blades 200 on the device, Figure 6From a medium perspective, the power shaft 300 is started and rotated clockwise by a certain angle. At this time, the hydraulic chamber 3 701, which is fixed to the hydraulic chamber 2 605, drives the force-bearing block 706 to rotate clockwise synchronously. This causes the force-bearing block 706 to be squeezed by the compression block 707. Because the end of the force-bearing block 706 away from the torsion spring block 705 is restricted by the connecting rod 704, the force-bearing block 706 is difficult to rotate around the torsion spring block 705 as the axis under this condition. Thus, the connecting rod 704 can move relative to the hydraulic chamber 3 701 under the action of the force-bearing block 706 and the compression block 707. At this time, the connecting rod 704 moves away from the hydraulic chamber 3 701. The movement reduces the pressure inside hydraulic chamber 701, causing baffle 702 inside hydraulic chamber 701 to compress and rotate the elastic telescopic plate 703 near the connecting rod 704. The connecting rod 704 continues to move, causing the pressure inside hydraulic chamber 605, which is connected to hydraulic chamber 701, to decrease synchronously. This drives transmission rod 607 to move, causing it to move via spring 609, which in turn moves limiting block 610 out of limiting groove 611. This removes the restriction between mounting cylinder 500 and soil-turning blade 200, allowing soil-turning blade 200 to move out of mounting cylinder 500 under gravity. When the device is performing normal soil-turning operation, Figure 6 From a medium perspective, the clockwise rotating power shaft 300 drives the hydraulic chamber 701 and the force-bearing block 706 to rotate counterclockwise. At this time, when the force-bearing block 706 rotates to the state of contact with the extrusion block 707, the force-bearing block 706 is not restricted by the connecting rod 704, so that the force-bearing block 706 drives the torsion spring block 705 fixedly connected to it to rotate. In this way, when the force-bearing block 706 rotates counterclockwise to the extrusion block 707, it can avoid the extrusion block 707 under the action of the torsion spring block 705, thus maintaining the normal operation of the device. Example

[0040] Please see Figures 1-9Based on Embodiments 1 and 2, the buffer assembly 800 includes a hydraulic device 801 connected to the hydraulic chamber 2 605, and a push rod 802 is slidably connected to the top of the hydraulic device 801. When the power shaft 300 rotates rapidly, causing the pressure inside the hydraulic chamber 2 605 to increase, the pressure inside the hydraulic device 801 connected to the hydraulic chamber 2 605 increases synchronously, driving the push rod 802, which is slidably connected to the hydraulic device 801, to move. A buffer chamber 803 is slidably connected to the inner wall side of the fixed plate 100. The buffer chamber 803 is located at the top of the push rod 802 and is fixed to the push rod 802. A buffer rod 805 is connected to the bottom of the inner wall of the buffer chamber 803 by a spring 3 804. A force-bearing plate 806 is fixedly connected to the top of the buffer rod 805. A buffer rubber block 807 is fitted to the inner wall side of the buffer chamber 803. When push rod 802 moves buffer chamber 803 closer to the power shaft 300, if the power shaft 300 vibrates due to excessive rotation, the power shaft 300 tends to press against the force plate 806. With the help of buffer rod 805, spring 804, and buffer rubber block 807 in buffer chamber 803, the power shaft 300, which vibrates slightly due to rapid rotation, can be buffered to a certain extent, further improving the stability of the device during use.

[0041] In use, based on Embodiment 1 and Embodiment 2, when the power shaft 300 rotates rapidly, causing the pressure inside the hydraulic chamber 2 605 to increase, the pressure inside the hydraulic device 801 connected to the hydraulic chamber 2 605 increases synchronously, driving the push rod 802, which is slidably connected to the hydraulic device 801, to move. This causes the push rod 802 to move the buffer chamber 803 towards the side closer to the power shaft 300. At this time, if the power shaft 300 vibrates due to excessive rotation, it tends to compress the force plate 806. With the help of the buffer rod 805, the spring 3 804, and the buffer rubber block 807 inside the buffer chamber 803, the power shaft 300, which vibrates slightly due to rapid rotation, can be buffered to a certain extent.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
