DETAILED DESCRIPTION OF THE INVENTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0018] See also Figures 1 - 5 , an agricultural tillage turning machine, comprising a fixing plate 100 and a tillage blade 200, wherein a power shaft 300 driven by a motor is rotatably connected inside the fixing plate 100, a mounting seat 400 is fixedly connected to the outside of the power shaft 300, and a mounting cylinder 500 is fixedly connected to the outside of the mounting seat 400; The outer side of the power shaft 300 is connected to the hydraulic chamber 1 601 in a transmission manner. The inner wall of the hydraulic chamber 1 601 is connected to the movable block 603 by setting an elastic expansion plate 1 602. The side of the hydraulic chamber 1 601 is slidably connected to the arc rod 604. In order to improve the soil turning efficiency and thus increase the speed of the power shaft 300, Figure 3 From a middle perspective, by quickly rotating the power shaft 300 counterclockwise, the hydraulic chamber 601 connected thereto can be synchronously driven to rotate quickly, so that the movable block 603 in the hydraulic chamber 601 stretches the elastic expansion plate 602 under the action of centrifugal force and slides along the inner wall of the hydraulic chamber 601, thereby increasing the pressure in the hydraulic chamber 601 slidably connected to the movable block 603, thereby driving the arc rod 604 slidably connected to the hydraulic chamber 601 to move.

[0019] The outer side of the mounting seat 400 is fixedly connected with a hydraulic bin 2 605, one end of which is slidably connected with a force rod 606, which is located on the side of the arc rod 604 and in contact with the arc rod 604, the other end of the hydraulic bin 2 605 is slidably connected with a transmission rod 607, the side of the force rod 606 is fixedly connected with a spring 1 608, the side of the transmission rod 607 is connected with a limiting block 610 via an assembly spring 2 609, a through opening is provided on the mounting tube 500, the cross-sectional shape of the opening is adapted to the transmission rod 607 and the limiting block 610, and limiting grooves 611 are provided on both sides of the soil-turning piece 200. The arc rod 604 that rotates with the hydraulic chamber 1 601 extends synchronously, squeezes the force rod 606, and makes the force rod 606 move to both sides, cooperates with the hydraulic chamber 2 605 that is slidably connected to the force rod 606, so that the pressure in the hydraulic chamber 2 605 increases, drives the transmission rod 607 that is slidably connected to the hydraulic chamber 2 605 to move, and the transmission rod 607 applies a certain force to the limiting block 610 through the spring 2 609, so that the limiting block 610 further moves into the limiting groove 611 on the soil turning piece 200. That is, the stability of the soil turning piece 200 when in use is maintained while improving the soil turning efficiency, thereby improving the soil turning effect of the device in this case.

[0020] When the rotation speed of the power shaft 300 slows down or stops, the moving block 603 loses the traction of centrifugal force and can be reset under the action of the elastic telescopic plate 602. Similarly, the arc-shaped rod 604 is reset, causing the force-bearing rod 606 to lose its restraint and be reset under the action of the first spring 608. Similarly, the transmission rod 607 is reset. In this way, the device can be restored to its initial state to facilitate the next use of the device.

[0021] When the soil-turning blade 200 is installed on the power shaft 300, the soil-turning blade 200 moves into the installation cylinder 500. The bottom side of the soil-turning blade 200 first presses against the limiting block 610, causing the limiting block 610 to press 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 position of the limiting block 610 as the soil-turning blade 200 moves, the limiting block 610 loses its restraint and is reset under the action of the second spring 609, thereby snapping into the limiting groove 611 to complete the installation of the soil-turning blade 200, making the device easier to use. The inside of the fixing plate 100 is respectively equipped with a replacement component 700 for replacing the soil-turning blade 200 and a buffer component 800 for maintaining stability.

[0022] During use, in order to improve the soil-turning efficiency and thus increase the rotation speed of the power shaft 300, Figure 3In the middle perspective, when the power shaft 300 rotates rapidly counterclockwise, it can synchronously drive the first hydraulic chamber 601 connected to it in transmission to rotate rapidly. Under the action of centrifugal force, the movable block 603 in the first hydraulic chamber 601 stretches the first elastic telescopic plate 602 and slides along the inner wall of the first hydraulic chamber 601, increasing the pressure in the first hydraulic chamber 601 connected to the movable block 603 in a sliding manner, driving the arc-shaped rod 604 connected to the first hydraulic chamber 601 in a sliding manner to move. At this time, the arc-shaped rod 604 rotating together with the first hydraulic chamber 601 extends synchronously, squeezing the stress rod 606, causing the stress rod 606 to move to both sides. Cooperating with the second hydraulic chamber 605 connected to the stress rod 606 in a sliding manner, the pressure in the second hydraulic chamber 605 increases, driving the transmission rod 607 connected to the second hydraulic chamber 605 in a sliding manner to move. The transmission rod 607 applies a certain force to the limiting block 610 through the second spring 609, causing the limiting block 610 to further move into the limiting groove 611 on the soil-turning blade 200; when the rotation 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 first elastic telescopic plate 602. Similarly, the arc-shaped rod 604 is reset, causing the stress rod 606 to lose its restraint and be reset under the action of the first spring 608. Similarly, the transmission rod 607 is reset. In this way, the device can be restored to its initial state; when the soil-turning blade 200 is installed on the power shaft 300, the soil-turning blade 200 moves into the installation cylinder 500. The bottom side of the soil-turning blade 200 first squeezes the limiting block 610, causing the limiting block 610 to squeeze 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 position of the limiting block 610 as the soil-turning blade 200 moves, the limiting block 610 loses its restraint and is reset under the action of the second spring 609, thereby snapping into the limiting groove 611 to complete the installation of the soil-turning blade 200. Embodiment

[0023] Please refer to Figures 1 - 7 , on the basis of Embodiment 1, the replacement component 700 includes a third hydraulic chamber 701. The third hydraulic chamber 701 is located on the side of the second hydraulic chamber 605, fixedly connected to and communicating with the second hydraulic chamber 605. A baffle 702 is rotatably connected inside the third hydraulic chamber 701. An elastic telescopic plate 703 is assembled on the side of the baffle 702. Each group of the elastic telescopic plates 703 has two, and the two elastic telescopic plates 703 are symmetrically distributed with respect to 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. A stress block 706 is fixedly connected to the outside of the torsion spring block 705. When it is necessary to remove and clean the soil-turning blade 200 on the device, Figure 6In the middle perspective, start the power shaft 300 and rotate it clockwise by a certain angle. At this time, the hydraulic chamber three 701 fixed to the hydraulic chamber two 605 drives the force receiving block 706 to rotate clockwise synchronously. An extrusion block 707 is fixedly connected to the inner wall of the fixing plate 100. When the force receiving block 706 rotates clockwise, the force receiving block 706 is extruded by the extrusion block 707. Also, since one end of the force receiving block 706 far from the torsion spring block 705 is restricted by the connecting rod 704, it is difficult for the force receiving block 706 to rotate around the torsion spring block 705 in this case. Thus, the connecting rod 704 can move relative to the hydraulic chamber three 701 under the action of the force receiving block 706 and the extrusion block 707. At this time, the connecting rod 704 moves to the side away from the hydraulic chamber three 701, reducing the pressure in the hydraulic chamber three 701. Then, the baffle 702 in the hydraulic chamber three 701 compresses the elastic telescopic plate two 703 on the side close to the connecting rod 704 and rotates. As the connecting rod 704 continues to move, the pressure in the hydraulic chamber two 605 communicated with the hydraulic chamber three 701 is synchronously reduced, driving the transmission rod 607 to move. The transmission rod 607 drives the limiting block 610 to move out of the limiting groove 611 through the spring two 609, canceling the restriction between the installation cylinder 500 and the soil turning blade 200. At this time, the soil turning blade 200 can move out of the installation cylinder 500 by itself under the action of gravity. The soil turning blade 200 on the device can be quickly removed, improving the use efficiency of the device.

[0024] When the device is performing normal soil turning operations, from Figure 6 the middle perspective, the clockwise rotating power shaft 300 drives the hydraulic chamber three 701 and the force receiving block 706 to rotate counterclockwise. At this time, when the force receiving block 706 rotates to a state in contact with the extrusion block 707, the force receiving block 706 is not restricted by the connecting rod 704, so that the force receiving block 706 drives the torsion spring block 705 fixedly connected to it to rotate. Thus, when the force receiving 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, maintaining the normal use of the device. While improving the use efficiency of the device, it will not have an additional impact on the soil turning operation of the device.

[0025] During use, on the basis of Embodiment 1, when it is necessary to remove and clean the soil turning blade 200 on the device, from Figure 6In the middle view, start the power shaft 300 and rotate it clockwise by a certain angle. At this time, the hydraulic chamber three 701 fixed to the hydraulic chamber two 605 drives the force-receiving block 706 to rotate clockwise synchronously, so that the force-receiving block 706 is squeezed by the squeezing block 707. Also, because one end of the force-receiving block 706 far from the torsion spring block 705 is restricted by the connecting rod 704, it is difficult for the force-receiving block 706 to rotate around the torsion spring block 705 in this situation. Thus, the connecting rod 704 can move relative to the hydraulic chamber three 701 under the action of the force-receiving block 706 and the squeezing block 707. At this time, the connecting rod 704 moves to the side away from the hydraulic chamber three 701, reducing the pressure in the hydraulic chamber three 701. Then, the baffle 702 in the hydraulic chamber three 701 compresses the elastic telescopic plate two 703 on the side close to the connecting rod 704 and rotates. As the connecting rod 704 continues to move, the pressure in the hydraulic chamber two 605 connected to the hydraulic chamber three 701 can be synchronously reduced, driving the transmission rod 607 to move, so that the transmission rod 607 drives the limiting block 610 to move out of the limiting groove 611 through the spring two 609, canceling the restriction between the installation cylinder 500 and the soil-turning blade 200. And at this time, the soil-turning blade 200 can move out of the installation cylinder 500 by itself under the action of gravity; when the device is performing normal soil-turning operations, taking Figure 6 In the middle view, the clockwise-rotating power shaft 300 drives the hydraulic chamber three 701 and the force-receiving block 706 to rotate counterclockwise. At this time, when the force-receiving block 706 rotates to a state of contacting the squeezing block 707, the force-receiving block 706 is not restricted by the connecting rod 704, so that the force-receiving block 706 drives the torsion spring block 705 fixedly connected to it to rotate. Thus, when the force-receiving block 706 rotates counterclockwise to the squeezing block 707, it can avoid the squeezing block 707 under the action of the torsion spring block 705 to maintain the normal use of the device. Embodiment

[0026] Please refer to Figures 1 - 9, on the basis of the first and second embodiments, the buffer assembly 800 includes a hydraulic device 801 communicated with the second hydraulic chamber 605. 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 in the second hydraulic chamber 605 to increase, the pressure in the hydraulic device 801 communicated with the second hydraulic chamber 605 increases synchronously, driving the push rod 802 slidably connected to the hydraulic device 801 to move. A buffer chamber 803 is slidably connected to the inner wall side of the fixing 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 through an assembly spring three 804. A force receiving plate 806 is fixedly connected to the top of the buffer rod 805. A buffer rubber block 807 is assembled on the inner wall side of the buffer chamber 803. When the push rod 802 drives the buffer chamber 803 to move toward the side close to the power shaft 300, if the power shaft 300 generates a certain vibration due to too fast rotation, the power shaft 300 has a tendency to squeeze the force receiving plate 806. Cooperating with the buffer rod 805, the spring three 804 and the buffer rubber block 807 in the buffer chamber 803, the power shaft 300 with slight vibration caused by rapid rotation can be buffered to a certain extent, further improving the stability of the device during use.

[0027] During use, on the basis of the first and second embodiments, when the power shaft 300 rotates rapidly, causing the pressure in the second hydraulic chamber 605 to increase, the pressure in the hydraulic device 801 communicated with the second hydraulic chamber 605 increases synchronously, driving the push rod 802 slidably connected to the hydraulic device 801 to move, so that the push rod 802 drives the buffer chamber 803 to move toward the side close to the power shaft 300; at this time, if the power shaft 300 generates a certain vibration due to too fast rotation, the power shaft 300 has a tendency to squeeze the force receiving plate 806. Cooperating with the buffer rod 805, the spring three 804 and the buffer rubber block 807 in the buffer chamber 803, the power shaft 300 with slight vibration caused by rapid rotation can be buffered to a certain extent.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
