[0001] The invention relates to the technical field of flood season soil and water conservation devices, and in particular to a flood season soil and water conservation device. Background Art

[0002] During the flood season, farmland is often washed away by heavy rains, which leads to a large loss of topsoil. Topsoil is a key factor in agricultural production. It contains a large amount of organic matter and nutrients, which are essential for plant growth. Soil loss not only reduces the fertility of farmland, but also may lead to land degradation and ecological environment deterioration, thus affecting the sustainability of agricultural production.

DETAILED DESCRIPTION

[0037] 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.

[0038] Reference Figure 1-10 An embodiment of the present invention discloses a flood season soil and water conservation device, which is installed in farmland and is used 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 with a traction device. As a preferred embodiment, the traction device described in this embodiment can be towed by a tractor to drive the device to move in the farmland for all-round operation;

[0039] Reference Figure 2 , Figure 3 A reel 2 is rotatably connected to the middle part of the frame 1, and an interception tube 3 is wound around the outside of the reel 2. Two roller units 4 are also rotatably connected to the frame 1, and 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 reel 2 during actual walking, in order to avoid the problem that the interception tube 3 is dragged due to the short length of the interception tube 3 being released when the angular velocity is the same, a speed change mechanism 5 for changing the speed of the reel 2 is provided between the roller unit 4 and the reel 2 in the present invention. The speed change mechanism 5 is used to change the rotation speed of the reel 2, so that when the winding outer diameter of the interception tube 3 outside it changes, its rotation speed also changes adaptively to ensure the stable winding of the interception tube 3.

[0040] Reference Figure 3In some embodiments, the vehicle frame 1 in the present invention includes a frame 11 and a transverse axis section 12 connected to the middle part of the frame 11. Specifically, the frame 11 in this embodiment is used to connect a traction device, and the transverse axis section 12 is installed in the middle part of the frame 11. The reel 2 and the roller unit 4 are both rotatably connected to the outside of the transverse axis 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 On the basis of the above embodiment, the interception tube 3 in this embodiment includes a deployment tube 31 and a storage tube 32. Of course, the deployment tube 31 and the storage tube 32 in this embodiment are both configured as hoses;

[0042] Reference Figure 3 , the unfolding tube 31 is wound around the outside of the reel 2, and a plurality of the receiving tubes 32 are provided, and the plurality of the receiving tubes 32 are arranged at intervals along the outer circumference of the unfolding tube 31 and are connected. Specifically, in this embodiment, the plurality of the receiving tubes 32 are divided into two rows and are connected to the outside of the unfolding tube 31, and the two rows of the receiving tubes 32 are arranged at a 180-degree angle to ensure that when the unfolding tube 31 is unwound onto 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 described in this embodiment is set as a waist-shaped hole, the purpose of 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 of and into the outlet 13 at the same time;

[0043] A gripping assembly 33 is further provided on the outer side of the receiving tube 32 , and the gripping assembly 33 is used to securely connect the receiving tube 32 to the ground of the farmland.

[0044] That is, in the present invention, by adopting a structural design in which a plurality of storage tubes 32 are connected on the deployment tube 31, the device is pulled by a traction device to move and unwind in the farmland when in use, and the deployment tube 31 can be laid in the farmland according to demand. After the laying of the tube is completed, water can be supplied to the inside of the deployment tube 31. The water supply mechanism 6 will be described in detail later and will not be described in detail here.

[0045] When water is supplied, the water pressure will push out the storage tube 32 horizontally stacked on the expansion tube 31. At this time, the storage tube 32 expands vertically and is placed on the ground of the farmland. As a preferred embodiment, the storage tube 32 described in this embodiment can adopt a vertical connection design with the expansion tube 31 to ensure the interception of water and soil. When the storage tube 32 expands, it is placed horizontally on the ground to form a plurality of 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 reducing the loss of surface soil due to rain erosion.

[0046] Reference Figure 5, Figure 6 In a preferred embodiment, the grip assembly 33 of the present invention comprises a plurality of fixing rings 331 installed at intervals on the outside of the receiving tube 32, a groove is provided on the outer circumference of the fixing ring 331, and a hand grip 332 is rotatably connected in the groove;

[0047] A cover 333 is fixedly installed at the end of the storage tube 32, and a driving structure for driving the hand grip 332 to rotate is provided on the cover 333. In this embodiment, the coupling force between the storage tube 32 and the ground after being unfolded is taken into consideration. Due to the high flow velocity of water in flood season, if the storage tube 32 and the ground are not well fixed, it is very easy for the storage tube 32 to bend and tilt under the erosion of water flow, which will affect the interception effect of water and soil. Therefore, in this embodiment, a plurality of hand grips 332 are arranged on the outside of the storage tube 32. When the storage tube 32 is unfolded, it can be grasped between the hand grip 332 and the ground to ensure the stability of the storage tube 32 after laying.

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

[0049] A compression spring 336 is fixedly connected between the piston 335 and the sealing cover 333, a pull rod 337 is fixedly installed on the driving rod 334 and is passed through the outside of the end fixing ring 331 in sequence, a reset 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 hand grip 332, and the eccentric rod 339 is connected to the pull rod 337. Of course, under this structural design, the rotating shaft and the hand grip 332 are also fixedly connected, so that when the rotating shaft rotates on the fixing ring 331, it will drive the hand grip 332 to perform a flipping movement.

[0050] Specifically, during the laying process, when the water supply causes the storage tube 32 to expand, the water pressure will move inside the storage tube 32, and after the storage tube 32 expands, it will resist the piston 335 to move. Of course, the piston 335 and the cover 333 slide tightly to avoid the problem of water leakage and pressure loss. Technical personnel in the relevant field 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 described in this embodiment is formed with a plurality of connecting arms, and the pull rod 337 is connected to the connecting arm. Therefore, when the drive rod 334 moves outward, it will drive the plurality of pull rods 337 to move horizontally synchronously with the help of the plurality of connecting arms. Since the eccentric rod 339 is connected to the pull rod 337, the pull rod 337 will drive the eccentric rod 339 to rotate when it moves, thereby further driving the hand grip 332 to rotate and open until it is engaged on 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 in the present embodiment 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 in the present embodiment, and a waist groove is opened on the side of the eccentric rod 339, and the guide shaft slides in the waist groove. In this way, when the pull rod 337 moves linearly, the sliding cooperation of the guide shaft and the waist groove can achieve the effect of driving the above-mentioned eccentric rod 339 to rotate, thereby enabling the hand grip 332 to produce a flipping movement.

[0052] Furthermore, after the flood prevention and protection operation is completed, when it is necessary to reel in the entire interception pipe 3, the water in the interception pipe 3 is first discharged. For this purpose, a valve can be installed at the end of the unfolding pipe 31 in the present invention, which can be used to open and discharge the water inside the entire interception pipe 3. At this time, the storage tube 32 will retract, and at the same time, the pull rod 337 will be driven to reset under the action of the reset spring 338. When the pull rod 337 moves and resets, it will drive multiple hand grips 332 to flip and reset, thereby separating the hand grips 332 from the ground to avoid the reeling operation of the entire interception pipe 3. When reeling, the storage tube 32 is horizontally stored on the outside of the unfolding tube 31, and is finally stored on the outside of the reel 2 under the rotation of the reel 2.

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

[0054] An escape position 43 is provided on the inner side of the wheel hub 41 . The escape position 43 in this embodiment is configured as a groove position, and a driving gear 44 is fixedly installed in the escape position 43 .

[0055] Reference Fig.10On the basis of the above-mentioned embodiment, the speed change mechanism 5 in this embodiment includes a planetary carrier 51 connected to the outside of the transverse shaft section 12, and a plurality of transmission gears 52 and driving gears 53 are rotated inside and outside 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 driving gear 53. In this way, the speed ratio is increased to ensure that the reel 2 can rotate quickly. Every two transmission gears 52 and driving gears 53 form a group and are coaxially connected. The transmission gear 52 is meshed with the driving gear 44. A driven gear 21 is also provided at the end of the reel 2, and a plurality of driving gears 53 are meshed on the outside of the driven gear 21.

[0056] That is to say, the present invention takes into account that during the winding process, due to the different diameters of the reel 2 and the rim 42, if the rim 42 directly drives the reel 2 to rotate, it will cause the reel 2 to be difficult to perform a constant length winding operation, thereby affecting the stable placement of the intercepting tube 3. Based on this problem, the present invention adopts a planetary gear structure for speed change, thereby ensuring that during winding, the reel 2 can maintain a constant length winding for the intercepting tubes 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 driving active gear 44 on the inner side of the hub 41 rotates. Since the active gear 44 is meshed with the transmission gear 52, the transmission gear 52 will rotate synchronously. When the transmission gear 52 rotates, it will drive the driving gear 53 coaxially connected thereto to rotate, and then through the meshing transmission of multiple driving gears 53, the driven gear 21 can be driven to rotate, so as to realize the rotation drive of the reel 2, so that in the initial state, the reel 2 and the roller unit 4 can maintain an initial speed ratio to ensure the winding or unwinding stability of the intercepting tube 3.

[0058] Reference Fig. 9 The above descriptions are all based on the example that the planetary carrier 51 is in a fixed position, and the gear ratio achieved is fixed. Of course, in the actual winding process, as the intercepting tube 3 is continuously wound and unwound, its outer diameter will change accordingly. Therefore, in order to always keep the reel 2 able to always maintain a constant winding and unwinding operation, a plurality of electromagnets 54 are embedded in the inner ring of the planetary carrier 51 in the present invention, and the electromagnet 54 and the transverse axis section 12 are electromagnetically braked. Of course, the electromagnet 54 described in the present invention is connected to an external control unit, and the control unit can be installed in a tractor, and the power supply voltage of the electromagnet 54 is changed to change the electromagnetic clamping force of the electromagnet 54 and the transverse axis section 12, so as to change the rotational damping force of the planetary carrier 51.

[0059] Specifically, when the reel 2 is fully wound, the outer diameter of the interception tube 3 on its outer side will change. At this time, the voltage of the electromagnet 54 can be changed to control its magnetic attraction. For example, when the magnetic attraction of the electromagnet 54 decreases, the planet carrier 51 will rotate slowly. The slower the planet carrier 51 rotates, the faster the driving gear 44 will drive the transmission gear 52 to rotate, so that the middle reel 2 rotates faster, thereby achieving an effect of accelerating the rotation of the reel 2.

[0060] Therefore, the rotational damping of the planetary carrier 51 can be changed, that is, the rotational speed of the intermediate reel 2 can be changed to achieve the effect of changing the transmission ratio, so that the reel 2 always maintains a constant unwinding length, so that it can adapt to the intercepting tubes 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 further includes a water supply mechanism 6;

[0062] The water supply mechanism 6 includes a water tank 61 installed on the frame 11, and the side of the water tank 61 is connected to a water outlet pipe 63 through an output pump 62. The other end of the water outlet pipe 63 is connected to the transverse axis section 12. The middle of the transverse axis section 12 has an opening section 14. A water inlet pipe 64 connected to and rotating in the opening section 14 is installed on the end surface of the reel 2, and the other end of the water inlet pipe 64 is connected to the intercepting pipe 3.

[0063] That is to say, when the intercepting pipe 3 is laid, it is in a loose state in the initial state. Therefore, the water in the water tank 61 can be pumped into the transverse axis section 12 through the output pump 62 to fill the intercepting pipe 3 with water. Specifically, the transverse axis section 12 described in this embodiment is a hollow tube structure, and the opening section 14 is designed to adapt to the rotation of the reel 2. When the water flows into between the opening section 14 and the reel 2, it will enter the intercepting pipe 3 along the water inlet pipe 64, so that the receiving tube 32 is filled with water and expanded to achieve the purpose of interception protection.

[0064] Reference Figure 3In order to further realize the utilization of energy, the side of the water tank 61 in the present invention is also connected to a water supply pipe 66 through a water suction pump 65, and the bottom end of the water supply pipe 66 faces the ground. Through the action of the water suction pump 65 and the water supply pipe 66, the water source in the field can also be absorbed to further improve the convenience of outdoor use. Furthermore, in the present invention, a guard plate 7 is also installed on the outside of the frame 11 and is sleeved on the outside of the reel 2. The guard plate 7 is used to protect the entire reel 2 and the interception tube 3 wrapped around the outside of the reel 2. Preferably, in this embodiment, the guard plate 7 is a circular structure with an opening, which is used to avoid the entry and exit of the interception tube 3. An elastic clamping plate can also be provided on the inner side of the guard plate 7 to clamp and fix the interception tube 3 after winding.

[0065] In summary, the present invention adopts the design of a retractable intercepting tube 3, which can form multiple intercepting protrusions in the farmland after being filled with water. 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 reducing the loss of surface soil due to rain erosion. Secondly, the present invention takes into account that the overall outer diameter of the intercepting tube 3 will change during the reeling process. Therefore, the present invention adopts the design of a speed changing mechanism 5 to ensure that the reel 2 can perform a constant length of reeling and unreeling operations, which greatly improves the stability of the laying and reeling of the intercepting tube 3.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
