Description

Technical Field

[0001] This invention relates to the field of water and soil protection devices during the flood season, and in particular to a water and soil protection device for the flood season. Background Technology

[0002] During the flood season, farmland is frequently eroded by torrential rains, leading to significant loss of topsoil. Topsoil is a crucial factor in agricultural production, containing abundant organic matter and nutrients essential for plant growth. Soil erosion not only reduces farmland fertility but can also lead to land degradation, ecological deterioration, and ultimately, impact the sustainability of agricultural production.

[0003] Traditional soil conservation methods, such as terracing and vegetation cover, can slow down soil erosion to some extent, but these methods often require a lot of manpower and resources and have limited effects. In particular, the application of these traditional methods is limited in areas with complex terrain that are difficult to carry out large-scale engineering modifications.

[0004] Based on this, in order to achieve convenient protection of farmland, we propose a water and soil protection device for the flood season. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for large amounts of manpower and material resources and limited effectiveness, and to propose a flood season soil and water protection device.

[0007] Design a flood season soil and water protection device, including:

[0008] A frame used for connection with traction equipment;

[0009] A drum is rotatably connected to the middle of the frame, and an intercepting tube is wound around the outside of the drum. Two roller units are also rotatably connected to the frame, and a speed-changing mechanism for changing the speed of the drum is provided between the roller units and the drum.

[0010] Furthermore, the frame includes a frame and a transverse shaft section connected in the middle of the frame, the drum and the roller unit are rotatably connected to the outside of the transverse shaft section, and the rear end of the frame is provided with an outlet for the intercepting tube to pass through.

[0011] Furthermore, the intercepting tube includes an unfolding tube and a receiving tube;

[0012] The unfolding tube is wound around the outside of the roll, and several receiving tubes are provided, which are spaced apart and connected along the outer periphery of the unfolding tube;

[0013] The outer side of the storage tube is also equipped with a ground gripping component.

[0014] Furthermore, the gripping assembly includes multiple fixing rings spaced apart on the outside of the storage tube, and the outer periphery of the fixing rings has a groove, in which a hand grip is rotatably connected;

[0015] The end of the storage tube is fixedly fitted with a cap, and the cap is provided with a drive structure for driving the gripper to rotate.

[0016] Furthermore, the drive structure includes a drive rod that is movably inserted into the cover, and a piston is fixedly connected to the inner end of the drive rod located in the cover;

[0017] A compression spring is fixedly connected between the piston and the cap. A pull rod is fixedly installed on the drive rod, which passes through the outer side of the end fixing ring in sequence. A return spring is fixedly connected between the tail end of the pull rod and the end fixing ring. An eccentric rod is fixedly connected to the rotating shaft of the gripper, and the eccentric rod is connected to the pull rod.

[0018] Furthermore, the roller unit includes a hub rotatably connected to the outside of the transverse shaft section, and a rim is fitted onto the outside of the hub;

[0019] The inner side of the hub is provided with a clearance position, and a drive gear is fixedly installed in the clearance position.

[0020] Furthermore, the transmission mechanism includes a planetary carrier connected to the outside of the horizontal shaft section. Multiple transmission gears and drive gears rotate on the inner and outer sides of the planetary carrier. Every two transmission gears and drive gears form a group and are coaxially connected. The transmission gears mesh with the driving gear. A driven gear is also provided at the end of the drum, and multiple drive gears mesh with the outside of the driven gear.

[0021] Furthermore, a number of electromagnets are embedded in the inner ring of the planetary carrier, and the electromagnets and the electromagnetic brake of the transverse axis section are also present.

[0022] Furthermore, this also includes water supply organizations;

[0023] The water supply mechanism includes a water tank installed on the frame. The side of the water tank is connected to an outlet pipe via an output pump. The other end of the outlet pipe is connected to the horizontal shaft section. The middle of the horizontal shaft section has an open section. An inlet pipe is installed on the end face of the drum, which communicates with and rotates in the open section. The other end of the inlet pipe is connected to the interception pipe.

[0024] Furthermore, the side of the water tank is connected to a water supply pipe via a water pump, with the bottom end of the water supply pipe facing the ground. A protective plate is also installed on the outside of the frame and fitted onto the outside of the drum.

[0025] The present invention proposes a flood season soil and water protection device, which has the following advantages: The invention employs a retractable interception tube design, which, after being filled with water, forms multiple interception protrusions in the farmland. This effectively intercepts and protects the soil and water matrix in the farmland during the flood season, preventing the loss of topsoil due to rainwater erosion. Furthermore, considering that the overall outer diameter of the interception tube changes during the rewinding process, the invention utilizes a variable speed mechanism to ensure that the drum can perform constant length rewinding and unwinding operations, greatly improving the stability of the interception tube's laying and rewinding.

[0037] 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.

[0038] Reference Figure 1-10 As an embodiment of the present invention, a flood season soil and water protection device is disclosed, which is installed in farmland to reduce soil and water loss during the flood season to achieve the purpose of protection. Specifically, the device includes a frame 1 for connecting to a traction device. In this preferred embodiment, the traction device can be a tractor to pull the device to move it in the farmland for all-round operation.

[0039] Reference Figure 2 , Figure 3 A drum 2 is rotatably connected to the middle of the frame 1, and an intercepting tube 3 is wound around the outside of the drum 2. Two roller units 4 are also rotatably connected to the frame 1. The two roller units 4 are used as the basis for walking support. Considering that the outer diameter of the roller unit 4 is larger than the outer diameter of the drum 2 during actual walking, in order to avoid the problem of the intercepting tube 3 being dragged due to the short release length when the angular velocity is the same, a speed changing mechanism 5 is provided between the roller unit 4 and the drum 2 to change the speed of the drum 2. The speed changing mechanism 5 is used to change the rotation speed of the drum 2. In this way, when the outer diameter of the intercepting tube 3 changes, its rotation speed also changes adaptively to ensure stable winding of the intercepting tube 3.

[0040] Reference Figure 3In some embodiments, the frame 1 of the present invention includes a frame 11 and a transverse shaft section 12 connected in the middle of the frame 11. Specifically, in this embodiment, the frame 11 is used to connect the traction device, the transverse shaft section 12 is installed in the middle section of the frame 11, the drum 2 and the roller unit 4 are rotatably connected to the outside of the transverse shaft section 12, and the tail end of the frame 11 is provided with an outlet 13 for the intercepting tube 3 to pass through.

[0041] Reference Figure 3 Based on the above embodiments, the intercepting tube 3 in this embodiment includes an unfolding tube 31 and a receiving tube 32. Of course, both the unfolding tube 31 and the receiving tube 32 in this embodiment are set as flexible tubes.

[0042] Reference Figure 3 The unfolding tube 31 is wound around the outside of the roll 2. Several receiving tubes 32 are provided, and the several receiving tubes 32 are arranged at intervals and connected along the outer periphery of the unfolding tube 31. Specifically, in this embodiment, the several receiving tubes 32 are divided into two rows connected to the outside of the unfolding tube 31. The two rows of receiving tubes 32 are arranged at 180 degrees to ensure that when the unfolding tube 31 is unwound to the ground, the receiving tubes 32 on both sides can be horizontally attached to the ground. In addition, as a preferred embodiment, the outlet 13 is set as an oblong hole, which is to adapt to the outer dimensions of the unfolding tube 31 and the receiving tube 32. Of course, a larger round hole can also be used to ensure that the unfolding tube 31 and the receiving tube 32 can be moved out and in from the outlet 13 at the same time.

[0043] The outer side of the storage tube 32 is also provided with a ground gripping component 33, which is used to securely connect the storage tube 32 to the ground of the farmland.

[0044] In this invention, by adopting a structural design that connects multiple storage tubes 32 to the unfolding tube 31, the device can be moved and unwound in the farmland by a traction device during use. The unfolding tube 31 can be laid in the farmland as needed. After the pipe is laid, water can be supplied to the inside of the unfolding tube 31. The water supply mechanism 6 will be described in detail later, and will not be elaborated here.

[0045] When water is supplied, the water pressure will push out the receiving pipe 32 that is horizontally stacked on the unfolding pipe 31. At this time, the receiving pipe 32 expands vertically and is placed on the ground of the farmland. In this preferred embodiment, the receiving pipe 32 can be designed to be vertically connected to the unfolding pipe 31 to ensure the interception of water and soil. When the receiving pipe 32 expands, it is placed horizontally on the ground to form multiple interception protrusions. In this way, during the flood season, the water and soil matrix in the farmland can be effectively intercepted and protected to avoid the problem of rainwater erosion and loss of topsoil.

[0046] Reference Figure 5, Figure 6 In a preferred embodiment, the gripping component 33 of the present invention includes a plurality of fixing rings 331 spaced apart on the outside of the storage tube 32, the outer periphery of the fixing rings 331 having a groove, and a gripper 332 being rotatably connected in the groove;

[0047] The end of the receiving pipe 32 is fixedly installed with a cap 333. The cap 333 is provided with a drive structure for driving the gripper 332 to rotate. In this embodiment, the coupling force between the receiving pipe 32 and the ground after it is unfolded is taken into consideration. Due to the high water flow velocity during the flood season, if the receiving pipe 32 is not properly fixed to the ground, it is very easy for the receiving pipe 32 to bend and tilt under the scouring of the water flow, which will affect the interception effect of water and soil. Therefore, in this embodiment, multiple grippers 332 are set on the outside of the receiving pipe 32. When the receiving pipe 32 is unfolded, it can be gripped tightly to the ground by the grippers 332 to ensure the stability of the receiving pipe 32 after it is laid.

[0048] Reference Figure 5 , Figure 6 , Figure 7 Specifically, in this embodiment, the driving structure includes a driving rod 334 that is movably inserted into the cover 333, and a piston 335 is fixedly connected to the inner end of the driving rod 334 located in the cover 333.

[0049] A compression spring 336 is fixedly connected between the piston 335 and the cover 333. A pull rod 337 is fixedly installed on the drive rod 334, which passes through the outer side of the end fixing ring 331. A return spring 338 is fixedly connected between the tail end of the pull rod 337 and the end fixing ring 331. An eccentric rod 339 is fixedly connected to the rotating shaft of the gripper 332. The eccentric rod 339 is connected to the pull rod 337. Of course, in this structural design, the rotating shaft is also fixedly connected to the gripper 332. When the rotating shaft rotates on the fixing ring 331, it will drive the gripper 332 to rotate.

[0050] Specifically, during the laying process, when the water supply causes the receiving pipe 32 to expand, the water pressure will move inside the receiving pipe 32 and move against the piston 335 after the receiving pipe 32 expands. Of course, the piston 335 and the cover 333 slide tightly to avoid water leakage and pressure loss. Those skilled in the art know that an exhaust hole can also be opened on the cover 333 to facilitate the movement of the piston 335. Furthermore, since the piston 335 drives the drive rod 334 to move outward, the outer end of the drive rod 334 in this embodiment is formed with multiple connecting arms. The pull rod 337 is connected to the connecting arms. Therefore, when the drive rod 334 moves outward, it will drive multiple pull rods 337 to move horizontally in sync with each other through the multiple connecting arms. Since the eccentric rod 339 is connected to the pull rod 337, the movement of the pull rod 337 will drive the eccentric rod 339 to rotate, which in turn drives the gripper 332 to rotate and open until it is locked onto the ground to achieve a stable laying effect.

[0051] It should be noted that, in order to ensure that the linear movement of the pull rod 337 can adapt to the rotational movement of the eccentric rod 339, a guide shaft can be fixedly installed on the side of the pull rod 337, and a groove can be opened on the side of the eccentric rod 339. The guide shaft slides in the groove. In this way, when the pull rod 337 moves linearly, the eccentric rod 339 will be driven to rotate through the sliding cooperation of the guide shaft and the groove, thereby enabling the gripper 332 to produce a flipping motion.

[0052] Furthermore, when the flood control protection operation is completed and the entire interception pipe 3 needs to be wound up, the water in the interception pipe 3 is first drained. For this purpose, a valve can be installed at the end of the unfolding pipe 31. The valve can be opened to drain the water inside the entire interception pipe 3. At this time, the receiving pipe 32 will retract, and under the action of the return spring 338, the pull rod 337 will be reset. When the pull rod 337 moves to reset, it will drive multiple grippers 332 to flip and reset, thereby separating the grippers 332 from the ground to avoid the winding operation of the entire interception pipe 3. When winding up, the receiving pipe 32 is horizontally stored outside the unfolding pipe 31, and finally stored outside the drum 2 under the rotation of the drum 2.

[0053] Reference Figure 9 In some embodiments, the roller unit 4 of the present invention includes a hub 41 rotatably connected to the outside of the horizontal shaft section 12, and a rim 42 is fitted on the outside of the hub 41.

[0054] The inner side of the hub 41 is provided with a clearance position 43. In this embodiment, the clearance position 43 is set as a groove position, and the drive gear 44 is fixedly installed in the clearance position 43.

[0055] Reference Figure 10Based on the above embodiments, the speed change mechanism 5 in this embodiment includes a planetary carrier 51 connected to the outside of the horizontal shaft section 12. Multiple transmission gears 52 and drive gears 53 rotate on the inner and outer sides of the planetary carrier 51. It should be noted that the diameter of the transmission gear 52 in this embodiment is smaller than that of the drive gear 53. This speed ratio is increased to ensure that the drum 2 can rotate quickly. Every two transmission gears 52 and drive gears 53 form a group and are coaxially connected. The transmission gear 52 meshes with the driving gear 44. A driven gear 21 is also provided at the end of the drum 2, and multiple drive gears 53 mesh with the outside of the driven gear 21.

[0056] In other words, this invention takes into account that during the winding process, since the diameters of the drum 2 and the rim 42 are different, if the rim 42 is rotated directly to drive the drum 2 to rotate, it will be difficult for the drum 2 to perform a constant length winding operation, thus affecting the stable placement of the intercepting tube 3. Based on this problem, this invention uses a planetary gear structure for speed change, so as to ensure that during winding, the drum 2 can maintain a constant length winding of the intercepting tube 3 with different outer diameters.

[0057] Specifically, when the frame 1 is moving and winding, the roller unit 4 will rotate when it contacts the ground. At this time, the drive gear 44 inside the hub 41 will rotate. Since the drive gear 44 and the transmission gear 52 mesh, the transmission gear 52 will rotate synchronously. When the transmission gear 52 rotates, it will drive the drive gear 53 connected to it on the same axis to rotate. Then, through the meshing transmission of multiple drive gears 53, the rotation of the driven gear 21 is achieved, thereby realizing the rotation drive of the drum 2. In the initial state, the drum 2 and the roller unit 4 can maintain an initial speed ratio rotation, ensuring the stability of the winding or unwinding of the interceptor tube 3.

[0058] Reference Figure 9 The above descriptions all assume that the planetary carrier 51 is in a fixed position, and the gear ratio it achieves is fixed. Of course, in the actual winding process, as the interceptor tube 3 is continuously wound and unwound, its outer diameter will change accordingly. Therefore, in order to always maintain a constant winding and unwinding operation, the inner ring of the planetary carrier 51 in this invention is equipped with several electromagnets 54. The electromagnets 54 and the transverse shaft section 12 are electromagnetically braked. Of course, the electromagnets 54 in this invention are connected to an external control unit. The control unit can be installed in a tractor. By changing the power supply voltage of the electromagnets 54, the electromagnetic clamping force of the electromagnets 54 and the transverse shaft section 12 can be changed, thereby changing the rotational damping force of the planetary carrier 51.

[0059] Specifically, when the drum 2 is wound up to a full circle, the outer diameter of the intercepting tube 3 on its outer side will change. At this time, the magnetic attraction force can be controlled by changing the voltage of the electromagnet 54. For example, when the magnetic attraction force of the electromagnet 54 decreases, the planetary carrier 51 will rotate slowly. The slower the planetary carrier 51 rotates, the faster the drive gear 44 will drive the transmission gear 52 to rotate, thus making the drum 2 in the middle rotate faster, thereby achieving the effect of accelerating the rotation of the drum 2.

[0060] Therefore, by changing the rotational damping of the planetary carrier 51, the rotational speed of the intermediate drum 2 can be changed to achieve the effect of changing the transmission ratio, so that the drum 2 always maintains a constant unwinding length. This can be adapted to the intercepting tube 3 with different stacked outer diameters to improve the winding stability of the intercepting tube 3.

[0061] Reference Figure 3 In some embodiments, the present invention also includes a water supply mechanism 6;

[0062] The water supply mechanism 6 includes a water tank 61 installed on the frame 11. The side of the water tank 61 is connected to a water outlet pipe 63 via an output pump 62. The other end of the water outlet pipe 63 is connected to the horizontal shaft section 12. The middle part of the horizontal shaft section 12 has an opening section 14. An inlet pipe 64 is installed on the end face of the drum 2, which communicates with and rotates in the opening section 14. The other end of the inlet pipe 64 is connected to the intercepting pipe 3.

[0063] In other words, when the intercepting pipe 3 is laid, it is initially in a soft state. Therefore, the water in the water tank 61 can be pumped into the horizontal shaft section 12 by the output pump 62 to fill the intercepting pipe 3 with water. Specifically, the horizontal shaft section 12 in this embodiment is a hollow tube structure. The design of the open section 14 is to adapt to the rotation of the drum 2. When the water flows into the space between the open section 14 and the drum 2, it will enter the intercepting pipe 3 along the water inlet pipe 64, thus filling the receiving pipe 32 with water and expanding it to achieve the purpose of interception and protection.

[0064] Reference Figure 3To further realize energy utilization, the side of the water tank 61 in this invention is also connected to a water supply pipe 66 via a water pump 65. The bottom end of the water supply pipe 66 faces the ground. Through the action of the water pump 65 and the water supply pipe 66, water sources existing in the field can also be drawn to further improve the convenience of outdoor use. Furthermore, in this invention, a protective plate 7 is also installed on the outside of the frame 11 and sleeved on the outside of the roll 2. The protective plate 7 is used to protect the entire roll 2 and the intercepting pipe 3 wound on the outside of the roll 2. Preferably, in this embodiment, the protective plate 7 is a circular structure with an opening, which is used to avoid the entry and exit of the intercepting pipe 3. An elastic clamping plate can also be provided on the inside of the protective plate 7 to clamp and fix the intercepting pipe 3 after winding.

[0065] In summary, by employing a retractable intercepting tube 3, this invention can form multiple intercepting protrusions in farmland after being filled with water. This effectively intercepts and protects the soil and water matrix in farmland during the flood season, preventing the loss of topsoil due to rainwater erosion. Furthermore, considering that the overall outer diameter of the intercepting tube 3 changes during the rewinding process, this invention employs a speed-changing mechanism 5 to ensure that the roll 2 can perform constant length rewinding and unwinding operations, greatly improving the stability of the laying and rewinding of the intercepting tube 3.

[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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.
