[0002] At present, the straw blind ditch grid device is a drainage facility made of straw as the main material. It is mainly composed of straw bundles, wrapping materials and grid frames. The straw bundle is the core part of the drainage, and there are many gaps inside it to guide the water flow. The geotextile is wrapped outside the straw bundle to play a filtering role to prevent soil particles from entering the straw and blocking the drainage channel. The grid frame plays the role of supporting and fixing the straw bundle, so that the whole device maintains a stable shape; When the accumulated water is diverted by burying straw bundles in the blind ditch and the soil is provided with fertility through the oxidation and degradation of the straw, since there is no gap or flow channel between the bottom of the straw bundle and the soil, the accumulated water cannot be drained out in time when there is a lot of accumulated water, and the degradation of the straw bundle is affected.

DETAILED DESCRIPTION

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.

[0015] The first embodiment, as Figure 1 to Figure 2 and Figures 5 to 8 As shown, the present invention provides a technical solution: a straw blind ditch grille device for controlling water and fertilizing, comprising: A frame 1, wherein a conduit assembly 3 is installed inside the frame 1, fixing mechanisms 2 are fixedly installed on both sides of the frame 1, and a geotextile 4 is installed between the fixing mechanisms 2; A straw bundle 5 is installed inside the geotextile 4, and the geotextile 4 is located inside the frame 1 and above the conduit assembly 3; Among them, the conduit assembly 3 includes an end ring 32, the number of which is two, and the end ring 32 is symmetrically installed at the bottom of the inner side of the frame 1 along the center position of the axis of the frame 1, and the outer side of the end ring 32 is symmetrically provided with a pipe groove, and a support tube 31 is installed between the end rings 32. The number of the support tube 31 is two, and the two ends of the outer side of the support tube 31 are fixedly connected to the pipe groove of the end ring 32. The support tube 31 contacts the bottom of the geotextile 4 to provide a certain support for the straw bundle 5 wrapped inside the geotextile 4, so that a certain space is formed between the bottom of the straw bundle 5 and the soil by using the support tube 31, thereby increasing the air content below the straw bundle 5 At the same time, the spiral grooves opened on the outside of the support tube 31 make the straw bundle 5 unable to drain the soil water in time when the amount of water is large. The excess water, under the action of its own gravity and the gap between the straw bundle 5, passes through the geotextile 4 along the spiral grooves on the surface of the support tube 31 and enters the interior of the support tube 31. The support tube 31 cooperates with the straw bundle 5 to drain the accumulated water. The outside of the support tube 31 is provided with spiral grooves, and the spiral grooves are distributed on the outside of the support tube 31 along the center position of the support tube 31, and the top of the support tube 31 is tightly fitted with the bottom of the geotextile 4.

[0016] A support beam 36 is installed between the support tubes 31, and both ends of the support beam 36 are fixedly connected to the inner wall of the frame 1, and an arc-shaped support plate 34 is fixedly installed on the top of the support beam 36, and both ends of the arc-shaped support plate 34 are arc-shaped and contact the bottom of the support tube 31, and the arc-shaped support plate 34 is evenly installed on the top of the support beam 36 along the axial direction, and a bottom support plate 35 is fixedly installed between the arc-shaped support plates 34, and the top of the bottom support plate 35 is in contact with the bottom of the support tube 31, and the non-opposite surfaces of the two end rings 32 are respectively fixedly installed with a bottom buckle ring 33 and a top buckle ring 37, The top buckle ring 37 is fixedly installed on the top of the outer side of the end ring 32. During the export process, the arc-shaped support plate 34 cooperates with the bottom support plate 35 to provide a certain support at the bottom of the support tube 31, and at the same time, the spiral groove at the bottom of the support tube 31 is blocked to a certain extent, thereby speeding up the export when there is a lot of water. The bottom buckle ring 33 is installed on the bottom of the outer side of the other end ring 32. A buckle groove is provided on the top of the outer side of the bottom buckle ring 33, and a buckle block is provided on the bottom of the outer side of the top buckle ring 37, and the buckle block of the top buckle ring 37 is adapted to the buckle groove of the bottom buckle ring 33.

[0017] The second embodiment is based on the first embodiment. Figure 3 to Figure 4 As shown, the frame 1 includes a grid frame 11, grids are arranged on both sides of the grid frame 11, and the two sides of the grid frame 11 are inclined inward from top to bottom, and the inner wall of the grid frame 11 is fixedly connected to the bottom of the outer side of the end ring 32, and the geotextile 4 is located on the inner side of the grid frame 11, and a top pressure plate 12 is fixedly installed on the top of the grid frame 11. The grid frame 11 provides a certain support for the internal structure. At the same time, the top pressure plate 12 on the top provides protection for the internal structure after being buried. When agricultural machinery passes through the top of the blind ditch, the top pressure plate 12 can provide support in the blind ditch. When passing through the machinery, the pressure caused by the machinery is prevented from being directly transmitted to the geotextile 4 and the geotextile 4 through the soil. The internal straw bundle 5 causes the straw bundle 5 to bend, affecting the water conduction smoothness of the straw bundle 5. The center position of the top of the top pressure plate 12 is a plane, and the two sides of the top of the top pressure plate 12 are inwardly concave arc surfaces. The top pressure plate 12 is evenly installed on the top of the grille frame 11 along the axial direction. The bottom of the grille frame 11 is fixedly installed with a ground plug 13. The two sides of the grille frame 11 are inclined inward from top to bottom. When the straw bundle 5 conducts water, a larger area of ​​accumulated water on the top is infiltrated, and in the process of infiltration, the accumulated water is concentrated and diverted, and quickly discharged. The number of the ground plugs 13 is several, and the ground plugs 13 are symmetrically installed on both sides of the bottom of the grille frame 11 along the center position of the axis of the grille frame 11.

[0018] The third embodiment is based on the first and second embodiments. Figures 9 to 11As shown, the fixing mechanism 2 includes a fixing plate 21, which is symmetrically installed on both sides of the inner wall of the grille frame 11 along the center position of the axis of the grille frame 11, and an arc groove is provided at the bottom of the outer side of the fixing plate 21. The fixing plate 21 is tightly fitted with the top of the outer side of the end ring 32 through the arc groove. A circular groove is opened at the center position of the outer side of the fixing plate 21, and a conical disk 22 is fixedly installed at the circular groove of the fixing plate 21, so that the two ends of the geotextile 4 pass through the circular groove of the fixing plate 21 and enter the interior of the slot tube 23, and the geotextile 4 is fixed by a clamp or a rope through the annular groove on the outer side of the slot tube 23, so that water guide ports appear at both ends of the geotextile 4. After being buried in the blind ditch, the water guide ports between the straw blind ditch grille devices correspond to each other to form a water guide channel, and a slot tube 23 is fixedly installed on the outer side of the conical disk 22, and the end of the slot tube 23 away from the conical disk 22 is an arc ring protruding outward.

[0019] An annular groove is provided on the outer side of the groove tube 23, and the groove tube 23 fixes the two ends of the geotextile 4 to the groove tube 23 through a clamp. A groove plate 25 is fixedly installed on the outer side of the fixing plate 21. The groove plate 25 is located on the inner side of the conical plate 22, and an oblique annular groove is provided on the inner wall of the groove plate 25. An arc pressure ring 24 is slidably installed at the oblique annular groove of the groove plate 25. The arc pressure ring 24 is evenly installed along the center position of the groove plate 25. After fixing the geotextile 4, the arc pressure ring 24 contacts the surface of the geotextile 4, and the elastic gasket ring 26 pushes the arc pressure ring 24 inward to apply pressure to the outer side of the geotextile 4, compressing it inward, so that the geotextile 4 tightly wraps the straw bundle 5, and an elastic gasket ring 26 is fixedly installed between the arc pressure ring 24 and the groove plate 25.

[0020] When in use, the straw bundle 5 is wrapped inside the geotextile 4, and the geotextile 4 wrapped with the straw bundle 5 is placed inside the frame 1, and the two ends of the geotextile 4 are fixed by the fixing mechanism 2, so that the geotextile 4 wrapped with the straw bundle 5 is at the top of the conduit assembly 3, and then a plurality of straw blind ditch grid devices are placed in the ditch and buried. When water accumulates on the land surface, the water seeps into the blind ditch and is subjected to the pressure of the soil through the frame 1. At the same time, after the water passes through the geotextile 4, a continuous drainage channel is formed through the natural hollow structure and irregular gaps inside the straw bundle 5 to divert the accumulated water. At the same time, when the amount of water is large, the water enters the conduit assembly 3 in the gap between its own gravity and the straw bundle 5, and the water is diverted through the conduit assembly 3 in cooperation with the straw bundle 5.

[0021] In the conduit assembly 3, the support tube 31 contacts the bottom of the geotextile 4 to provide a certain support for the straw bundle 5 wrapped inside the geotextile 4, so that a certain space is formed between the bottom of the straw bundle 5 and the soil by the support tube 31, and the air content under the straw bundle 5 is increased. At the same time, the spiral grooves opened on the outside of the support tube 31 make the straw bundle 5 accumulate a large amount of water in the process of diverting soil water. When the straw bundle 5 cannot drain the accumulated water in time, the excess water passes through the geotextile 4 under the action of its own gravity and the gap between the straw bundle 5, and enters the interior of the support tube 31 along the spiral grooves on the surface of the support tube 31. The accumulated water is drained out through the support tube 31 in cooperation with the straw bundle 5. At the same time, during the drainage process, the arc-shaped support plate 34 cooperates with the bottom support plate 35 to provide a certain support at the bottom of the support tube 31, and at the same time, the spiral grooves at the bottom of the support tube 31 are blocked to a certain extent, so as to speed up the drainage when there is a lot of water.

[0022] In the frame 1, the grille frame 11 provides a certain support for the internal structure, and the top pressure plate 12 provides protection for the internal structure after being buried. When agricultural machinery passes through the top of the blind ditch, the top pressure plate 12 can provide support in the blind ditch. When passing through the machinery, the pressure caused by the machinery is prevented from being directly transmitted to the geotextile 4 and the straw bundle 5 inside the geotextile 4 through the soil, causing the straw bundle 5 to bend and affecting the water conduction smoothness of the straw bundle 5. At the same time, the inclined structure on both sides of the grille frame 11 from top to bottom allows a larger area of ​​accumulated water on the top to infiltrate when the straw bundle 5 conducts water, and in the process of infiltration, the accumulated water is concentrated and diverted for rapid discharge.

[0023] When the geotextile 4 is fixed by the fixing mechanism 2, the two ends of the geotextile 4 pass through the circular groove of the fixing plate 21 and enter the interior of the slot tube 23, and the geotextile 4 is fixed by a clamp or a rope through the annular groove on the outer side of the slot tube 23, so that water guide ports appear at both ends of the geotextile 4. After being buried in the blind ditch, the water guide ports between the straw blind ditch grid devices correspond to each other to form a water guide channel. At the same time, after the geotextile 4 is fixed, the arc pressure ring 24 contacts the surface of the geotextile 4, and the elastic gasket ring 26 pushes the arc pressure ring 24 inward to apply pressure to the outer side of the geotextile 4, compressing it inward, so that the geotextile 4 tightly wraps the straw bundle 5.

[0024] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
