DETAILED DESCRIPTION

[0014] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0015] A saline-alkali land improvement device using crop straws comprises a connecting frame 3, one end of which is provided with a dispersed transmission component, and the dispersed transmission component is used for dispersed transmission of the straws; The dispersion transmission component includes a receiving channel 10, which is fixedly arranged at one end of the connecting frame 3. A rotating ring 12 is rotatably arranged on the upper side of the connecting channel. A distribution pipe 13 with an inclined bottom cross section is fixedly arranged on the upper side of the rotating ring 12. A group of circumferentially evenly arranged dispersion baffles 29 are fixedly arranged on the inner wall of the distribution pipe 13. The other side of the dispersion baffle 29 is fixedly connected to the circumferential outer wall of the dispersion block 28. The height of the dispersion baffle 29 corresponds to the height of the distribution pipe 13. The upper side of the dispersion baffle 29 is fixedly connected to the feed pipe 16. The upper side of the dispersion block 28 is conical, which is used to assist in dispersing the straw so that it can be dispersed into the straw channel formed between the adjacent partitions 29. The upper end of the receiving channel 10 is closed, and a feed port 101 is provided on the side of the upper end of the receiving channel 10 away from the connecting frame 3. When the rotating ring 12 performs the falling program according to the set falling time or falling distance, the rotating ring 12 rotates half a circle, and the distribution pipe 13 rotates to a position away from the connecting frame 3. The closed area on the upper side of the receiving channel 10 does not move, and the straw falls when it follows the distribution pipe 13 to rotate to the feed port 101; The angle between the bottom slope of the distribution pipe 13 and the horizontal plane of the connecting frame 3 is 50 degrees to 70 degrees. The setting of this angle enables the distribution pipe 13 to be inclined in the direction of the transmission belt. Under the action of gravity and the blocking action of the dispersion block 28, the straw is inclined and scattered between the dispersion partitions 29 corresponding to the position where the feed port 101 is not set on the upper side of the receiving channel 10, and the closed area on the upper side of the receiving channel 10 blocks the straw from falling; The bottom surface of the partition 29 is an inclined surface, and the inclination angle of the bottom surface of the partition 29 is the same as the inclination angle of the bottom inclined surface of the distribution pipe 13, and the bottom surface of the partition 29 and the bottom inclined surface of the distribution pipe 13 are on the same inclined surface.

[0016] As a further limitation of the present technical solution, it also includes a rotating component, which is used to drive the rotation of the rotating ring 12, thereby driving the rotation of the distribution pipeline 13, and the rotating component includes a belt 11, a motor 14 and a pulley 15. The rotating ring 12 and the pulley 15 are connected through the transmission of the belt 11, the motor 14 is fixed on the lower side of one end of the connecting frame 3, the output shaft of the motor 14 is fixedly connected to the central axis of the pulley 15, and the central axis of the pulley 15 is rotatably connected to the connecting frame 3.

[0017] In this embodiment, the motor 14 can drive the pulley 15 to rotate, and then drive the rotating ring 12 and the distribution pipe 13 to rotate through the belt 11; The motor 14 is connected to the motor 14 driver, and the motor 14 is a stepper motor 14. The output shaft of the motor 14 is controlled to rotate by the motor 14 driver (an existing product of the prior art, which will not be described in detail and will not be shown in the figure), so as to finally realize that after driving the distribution pipe 13 to rotate 180 degrees, it rotates 180 degrees in the opposite direction to return to its original position, thereby driving the distribution pipe 13 to rotate continuously back and forth. The motor 14 drives the pulley 15 to rotate, and the pulley 15 drives the rotating ring 12 to rotate on the upper side of the receiving channel 10 through the belt 11, thereby causing the distribution pipe 13 to rotate accordingly. After the straw enters the distribution pipe 13 from the feed pipe 16, the conical upper side of the dispersion block 28 disperses the straw to the surroundings, and guides the straw into the straw channel formed between adjacent dispersion partitions 29. Since the bottom slope of the distribution pipe 13 is at an angle of 50 to 70 degrees with the horizontal plane of the connecting frame 3, the straw is transmitted downward along the straw channel and the receiving channel 10 under the action of gravity, so as to realize the dispersed transmission of the straw. In addition, since a feed port 101 is provided, when the opening 901 of the feed pipe 16 connected to the distribution pipe 13 faces one end of the connecting frame 3, most of the straw will be blocked by the portion of the upper end of the distribution pipe 13 where the feed port 101 is not provided, and most of the straw will not fall. The straw is dispersed in the straw channel formed by the distribution channel partition 29. In the process of the motor 14 driving the distribution pipe 13 to rotate, the straw channels correspond to the feed port 101 one by one. After the distribution pipe 13 rotates 180 degrees, all the straw channels have completed the process of corresponding to the feed port 101. When the straw channel corresponds to the feed port 101, the straw falls into the receiving channel 10 and is finally discharged from the discharge channel 9.

[0020] As a further limitation of the present technical solution, the conveyor belt assembly 1 includes a driving machine 22, a conveyor belt 23 and a conveying wheel 24, the conveying wheel 24 is rotatably connected to the bracket 2, the conveying wheels 24 are respectively arranged at both ends of the bracket 2, the conveying wheels 24 are connected through the transmission of the conveyor belt 23, the output shaft of the driving machine 22 is fixedly connected to one end of the conveying wheel 24, and the driving machine 22 is fixed on the connecting frame 3.

[0021] In this embodiment, the driving machine 22 can be a diesel engine or an electric motor, etc. The driving machine 22 serves as the power source of the conveyor belt assembly 1, and its output shaft drives the conveyor wheel 24 to rotate. Due to the friction between the conveyor wheel 24 and the conveyor belt 23, the conveyor belt 23 starts to operate, thereby realizing horizontal transportation of the straw and allowing the straw to reach the discharge channel 20.

[0022] As a further limitation of the present technical solution, an opening 901 is provided at the lower end of the discharge channel 9, and a stopper 25 is fixedly provided at the upper portion of the discharge channel 9 corresponding to the opening 901. The upper side of the stopper 25 is an inclined surface and the inclined surface extends downward along the centerline direction of the discharge channel 9. A motor 26 is fixedly provided at the lower end of the discharge channel 9, and the output shaft of the motor 26 is fixedly connected to a bending part 27. The bending part 27 is provided on the lower side of the stopper 25. The bending part 27 will not interfere with the stopper 25 when being driven to rotate by the motor 26, and the bending part 27 is L-shaped.

[0023] In this embodiment, the inclined surface of the stopper 25 guides the straw to fall, and the motor 26 drives the bending member 27 to rotate. By controlling the rotation of the bending member 27, the straw is assisted to fall and pressed down so that the straw is pressed into the soil.

[0024] As a further limitation of the technical solution, wheels 7 are further included, and the wheels 7 are rotatably provided at the lower parts of both sides of the connecting frame 3.

[0025] As a further limitation of the present technical solution, the central axes of the rotary tilling wheels 8 are rotatably arranged at the lower parts of both sides of the connecting frame 3.

The rotary tillage wheels 8 are connected to the rotation of the engine, and the engine is fixed on the connecting frame 3. During the movement, the rotary tillage wheels 8 are rotated by the engine to perform rotary tillage operations to achieve soil loosening.

[0028] The method of use of the present invention is: Install the equipment on the traction vehicle through the mounting hole 4 at the other end of the connecting frame 3 to ensure a firm connection.

After the straw enters the distribution pipe 13 from the feed pipe 16, it is dispersed The conical upper side of block 28 disperses the straw to the surroundings and guides the straw into the straw channel. Due to the angle between the bottom slope of the distribution pipeline 13 and the horizontal plane of the connecting frame 3, the straw is transmitted downward along the straw channel and the receiving channel 10 under the action of gravity. The straw enters the discharge channel 9 through the receiving channel 10. The slope of the block 25 guides the straw to fall, and the motor 26 drives the bending part 27 to rotate to press the straw into the soil. At the same time, the traction vehicle drives the equipment to move on the saline-alkali land, and the rotary tillage wheels 8 on both sides of the connecting frame 3 are driven by the engine to perform rotary tillage and loosening of the soil to complete the saline-alkali land improvement operation.
