Description

Technical Field

[0001] The present invention relates to an irrigation and conveying device, in particular to a vertical and horizontal mixed anti-blocking irrigation and conveying device used in the field of agricultural irrigation. Background Art

[0002] Drip irrigation is a precise irrigation method that uses a low-pressure pipe system to deliver water directly to the field. The water is then dripped evenly and slowly into the soil near the crop root zone through emitters, orifices or drip tapes installed on capillary tubes, so that the soil in the area where the crop root system is most developed always maintains an appropriate humidity.

[0003] The specification of Chinese patent CN112262742B discloses a drip irrigation belt pressure stabilization and control system and method, comprising: a water pump, a drip irrigation belt, a plurality of drip irrigation belts, a water diversion valve provided between the drip irrigation belt and the delivery pipeline; a plurality of pressure stabilizing devices provided in the drip irrigation belt, and the pressure stabilizing devices correspond one-to-one to the drip irrigation holes on the drip irrigation belt, and the arrangement of the pressure stabilizing devices ensures that the flow rate of water flowing out of the drip irrigation holes on the same drip irrigation belt is the same; a detection and adjustment device, at least one detection and adjustment device is provided on the outside of each drip irrigation belt, and the detection and adjustment device is provided at the drip irrigation hole, and the detection and adjustment device is used to detect the flow rate of water flowing out of the drip irrigation hole and adjust the flow rate of water flowing out of the drip irrigation hole. The present invention can perform drip irrigation according to crop needs and prevent sediment in the water from clogging the drip irrigation hole.

[0004] The specification of Chinese patent CN112655526B discloses a water-saving irrigation system and method for corn fields. By automatically detecting soil moisture and sunlight intensity in the corn fields at multiple points, a centralized controller adjusts the operating power of the water pump and the opening and closing degree of the branch valve and nozzle solenoid valve according to the soil moisture and sunlight intensity, thereby adjusting the irrigation intensity and achieving the purpose of water saving while ensuring effective irrigation.

[0005] Most existing drip irrigation systems use valves or water pressure regulation to control the dripping speed of the drip irrigation belt. However, this method changes the irrigation speed of the entire drip irrigation belt and uniformly adjusts the irrigation volume of the area along the entire drip irrigation belt. However, in actual environments, due to factors such as terrain and crop needs, the soil along the drip irrigation belt may require different irrigation needs, but existing drip irrigation equipment is difficult to achieve local irrigation control. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that it is difficult for the existing drip irrigation equipment to achieve different irrigation controls on local soil.

[0007] To solve the above problems, the present invention provides a vertical and horizontal hybrid anti-blocking irrigation and delivery device, comprising a main water pipe and a plurality of evenly distributed main drip irrigation belts fixedly connected to the main water pipe, and also comprising at least one pair of auxiliary drip irrigation belts, wherein the auxiliary drip irrigation belts are horizontally arranged on the plurality of main drip irrigation belts and vertically distributed with the main drip irrigation belts, and the main drip irrigation belts and the auxiliary drip irrigation belts are connected by a cross member, and the cross member comprises a square seat, wherein a confluence groove is provided at the center position of the upper end of the square seat, wherein a main pipe groove is provided on one pair of non-adjacent inner walls of the confluence groove, and an auxiliary pipe groove is provided on the other pair of non-adjacent inner walls, the main drip irrigation belt is placed inside the pair of main pipe grooves, and the auxiliary drip irrigation belt is placed inside the pair of auxiliary pipe grooves; The main drip irrigation belt and the auxiliary drip irrigation belt are respectively provided with a main incision and an auxiliary incision in the local area inside the confluence trough. The inner walls of the main drip irrigation belt and the auxiliary drip irrigation belt are fitted with a pair of support rings. The multiple support rings are respectively located inside the main pipe groove and the auxiliary pipe groove. The upper end of the square seat is connected to a seal by a main bolt.

At this time, the water in the main drip irrigation belt is transported to the auxiliary drip irrigation belt through the cross piece, and also penetrates into the soil through the small holes in the auxiliary drip irrigation belt. In the local area c, the main drip irrigation belt and the auxiliary drip irrigation belt are combined to achieve vertical and horizontal mixed micro-irrigation; Step 3: Local flow stop: S3.1. Select a pair of auxiliary drip irrigation tapes of appropriate length based on the lateral width of the local area a where irrigation is to be stopped, and place them on either side of the local area a in the longitudinal direction. S3.2, repeat S2.2; S3.3. Select multiple sealing members and insert them into the multiple cross members to squeeze and seal all the main drip irrigation tapes flowing through area a. This eliminates any significant flow through the main drip irrigation tapes in area a, while water continues to flow through the main drip irrigation tapes in the remaining areas. This stops flow in area a, while the remaining areas continue to receive normal micro-irrigation. Step 4: Local throttling: S4.1. Select a pair of auxiliary drip irrigation tapes of appropriate length based on the lateral width of the local area b to be throttled, and place the pair of auxiliary drip irrigation tapes on both longitudinal sides of the local area b; S4.2, repeat S2.2; S4.3. Select multiple pipe sealing parts, insert them into the cross parts at intervals, and perform interval squeezing and blocking on multiple main drip irrigation belts flowing through area b, so as to increase the irrigation spacing in area b and achieve flow-saving irrigation in area b.

[0009] As a further supplement to the present application, the sealing member includes a cover plate and a pair of short vertical plates and a pair of long vertical plates fixedly connected to the lower end of the cover plate.

[0013] As a further supplement to the present application, the outer ends of the short vertical plates, the long vertical plates and the pressure plates, as well as the inner walls of the main pipe groove and the auxiliary pipe groove are all fixedly connected with elastic sealing layers.

[0014] As another improvement of the present application, the square seat is fixedly connected to a water inlet pipe and a water outlet pipe, and both ends of the water inlet pipe and the water outlet pipe are connected to the confluence trough and the outside world.

[0016] To sum up, the present application lays a secondary drip irrigation belt longitudinally on the existing main drip irrigation belt that is laid uniformly in the horizontal direction, and closes and connects the intersection of the main drip irrigation belt and the secondary drip irrigation belt through a cross piece as the water flow intersection between the two. During irrigation, according to the different irrigation needs of the soil in different areas, on the one hand, the local soil can be irrigated intensified by the main drip irrigation belt and the secondary drip irrigation belt mixed vertically and horizontally. On the other hand, the water inlet side or the water outlet side of the main drip irrigation belt can be blocked by the cross piece, so that no water flows through the middle section of multiple main drip irrigation belts in the local soil area, and local stop flow or local throttling irrigation operations are performed, and the remaining areas are still in normal micro-irrigation state. Therefore, the present application effectively realizes the dynamic adjustment and optimization of irrigation scheme according to soil or crop needs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method: The present invention provides a vertical and horizontal mixed anti-blocking irrigation and delivery device, please refer to Figure 1 and Figure 2 , including a main water pipe 1 and a plurality of evenly distributed main drip irrigation belts 2 fixedly connected to the main water pipe 1. The main water pipe 1 and the main drip irrigation belt 2 are laid in an existing drip irrigation manner, and the two are generally connected by a joint. The main drip irrigation belt 2 can be a patch-type drip irrigation belt, and the internal water flow overflows through the small holes on the patch.

[0021] See also Figure 2 、 Figure 3 and Figure 4 The present application also includes at least one pair of auxiliary drip irrigation belts 3, which are of the same type as the main drip irrigation belts 2. The auxiliary drip irrigation belts 3 are horizontally arranged on multiple main drip irrigation belts 2 and distributed vertically with the main drip irrigation belts 2. The main drip irrigation belts 2 and the auxiliary drip irrigation belts 3 are connected by cross pieces. The cross pieces include square seats 4. A confluence groove is provided at the center position of the upper end of the square seat 4. A main pipe groove 401 is provided on one pair of non-adjacent inner walls of the confluence groove, and a secondary pipe groove 402 is provided on the other pair of non-adjacent inner walls. The center lines of the pair of main pipe grooves 401 are on the same straight line, and the center lines of the pair of secondary pipe grooves 402 are on the same straight line. This makes it convenient to place the main drip irrigation belt 2 inside a pair of main pipe grooves 401 and to place the auxiliary drip irrigation belt 3 inside a pair of secondary pipe grooves 402.

[0022] See also Figure 4 and Figure 5The main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 are respectively provided with a main incision 201 and an auxiliary incision 301 in the local area inside the confluence trough (the two can be formed by the following method: Figure 6 As shown, a cutter is used to cut a long notch at the fold edge of the unused flat main drip irrigation belt 2 (or auxiliary drip irrigation belt 3). A pair of support rings 6 are fitted on the inner walls of the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3. The outer diameter of the support ring 6 is the same as the inner diameter of the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3. Since the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 are flexible structures, the support ring 6 can be inserted into the corresponding main drip irrigation belt 2 or auxiliary drip irrigation belt 3 through the main incision 201 or the auxiliary incision 301. After the insertion is completed, the placement position and state of the support ring 6 are adjusted so that the support ring 6 props up the inside of the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3, so that when the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 are installed in the square seat 4, multiple support rings 6 are just located inside the main pipe groove 401 and the auxiliary pipe groove 402, respectively.

[0023] See also Figure 3 and Figure 7 The upper end of the square seat 4 is connected to the sealing member 5 through the main bolt. The cover plate 51 is provided with a plurality of screw holes. The upper end of the square seat 4 is provided with a plurality of screw grooves 403. The main bolt passes through the screw hole and is threadedly connected to the inner part of the screw groove 403. Figure 5 and Figure 8 As shown, the sealing member 5 includes a cover plate 51 and a pair of short vertical plates 52 and a pair of long vertical plates 53 fixedly connected to the lower end of the cover plate 51. The pair of short vertical plates 52 are respectively inserted into a pair of main pipe grooves 401 and abut against the support rings 6 on the inner side thereof. The pair of long vertical plates 53 are respectively inserted into a pair of secondary pipe grooves 402 and abut against the support rings 6 on the inner side thereof. The support rings 6 are hard structures.

[0024] See also Figure 5 and Figure 7 The inner bottom surfaces of the main pipe groove 401 and the auxiliary pipe groove 402 are both concave semicircular structures, which match the shapes of the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 after being filled with water. The lower ends of the short vertical plates 52 and the long vertical plates 53 are both concave semicircular structures, which are convenient for matching with the annular structure of the support ring 6. The short vertical plates 52, the long vertical plates 53 and the inner walls of the main pipe groove 401 and the auxiliary pipe groove 402 are fixedly connected with an elastic sealing layer, such as elastic sealing rubber, which can improve the tightness of the connection between the above structures and with other structures (such as the abutment between the short vertical plates 52, the long vertical plates 53 and the support ring 6).

[0025] Since the depth of the main pipe groove 401 is smaller than the depth of the auxiliary pipe groove 402, after the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 are installed in the square seat 4, the main drip irrigation belt 2 is located on the upper side of the auxiliary drip irrigation belt 3. During irrigation, the water flow in the main drip irrigation belt 2 will flow out through the main incision 201, gather in the confluence groove, and enter the auxiliary drip irrigation belt 3 through the auxiliary incision 301. The confluence groove is closed on all sides through the close fit of the short vertical plate 52 and the main pipe groove 401, the close fit of the long vertical plate 53 and the auxiliary pipe groove 402, and the extrusion fit between the short vertical plate 52, the long vertical plate 53 and the support ring 6. Combined with the sealing of the upper port of the confluence groove by the cover plate 51, the square seat 4 serves as the water flow intersection between the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3. At the same time, the intersecting water flow is not easy to overflow and leak outward, and is not easy to affect the irrigation of the soil.

[0026] See also Figure 9 and Figure 10 , the interior of the main pipe groove 401 and the auxiliary pipe groove 402 is also provided with a sealing pipe part 7 that matches itself. The upper end of the sealing pipe part 7 is connected to the square seat 4 by a secondary bolt 8. The sealing pipe part 7 includes a cross bar 71 and a pressure plate 72 fixedly connected to the lower end of the cross bar 71. A pair of lock holes are provided on the cross bar 71, and a plurality of screw grooves 404 are provided on the upper end of the square seat 4. The secondary bolt 8 passes through the lock hole and is threadedly connected to the interior of the screw groove 404. The lower end of the pressure plate 72 is a convex semicircular structure, which is convenient for matching the concave semicircular structure of the inner bottom surface of the main pipe groove 401 and the auxiliary pipe groove 402. The outer end of the sealing pipe part 7 is also fixedly connected with an elastic sealing layer. When the main drip irrigation belt 2 or the auxiliary drip irrigation belt 3 is sealed by the sealing pipe part 7, it is effectively squeezed into a flat shape (combined with Figure 11 As shown), it is difficult for water to flow through the squeezed area.

[0027] A vertical and horizontal hybrid anti-blocking irrigation and delivery device, the use method of which comprises the following steps: Step 1: Full-area irrigation: In the agricultural area that needs irrigation, use the existing installation method to evenly connect multiple main drip irrigation belts 2 to the main water pipe 1, then connect the main water pipe 1 to the water source, and supply water to the main drip irrigation belts 2 through the main water pipe 1. The water slowly flows out through the small holes on the main drip irrigation belts 2 and penetrates into the soil to achieve micro-irrigation. This irrigation method is an existing drip irrigation method (such as Figure 1 (Shown in the structure in the upper left corner); Step 2: Local hydration: S2.1. Select multiple auxiliary drip irrigation belts 3 according to the area of the local area c that needs water replenishment, and evenly distribute them in the area c; S2.2. Cut a primary incision 201 and a secondary incision 301 at the intersection of the primary drip irrigation belt 2 and the secondary drip irrigation belt 3, respectively. Place a pair of support rings 6 in each of the primary drip irrigation belt 2 and the secondary drip irrigation belt 3 through the primary incision 201 and the secondary incision 301, and connect the primary drip irrigation belt 2 and the secondary drip irrigation belt 3 at the intersection using a cross piece. S2.3, such as Figure 1 As shown in the structure in the lower right corner, at this time, the water flow in the main drip irrigation belt 2 is transported to the auxiliary drip irrigation belt 3 through the cross piece, and also penetrates into the soil through the small holes on the auxiliary drip irrigation belt 3, so that in the local area c, the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 are combined to achieve vertical and horizontal mixed micro-irrigation.

[0028] Step 3: Local flow stop: S3.1. Select a pair of auxiliary drip irrigation tapes 3 of appropriate length based on the lateral width of the local area a where irrigation is to be stopped, and place the pair of auxiliary drip irrigation tapes 3 on both longitudinal sides of the local area a. S3.2, repeat S2.2; S3.3. Select multiple pipe sealing members 7 and insert them into multiple cross members respectively to squeeze and seal all the main drip irrigation belts 2 flowing through area a, so that no obvious water flows through the main drip irrigation belts 2 in area a, while water still flows through the main drip irrigation belts 2 in other areas, thus stopping the flow in area a and allowing normal micro-irrigation in other areas (such as Figure 1 As shown in the upper right corner or as Figure 2 shown); Please refer to the specific stop flow principle Figure 2 、 Figure 11 and Figure 12 First, for the multiple square seats 4 on the auxiliary drip irrigation belt 3 close to the main water pipe 1, except for a pair of square seats 4 on both sides of the edge, the remaining square seats 4 are installed with sealing members 7, and the sealing members 7 are installed in the main pipe groove 401 away from the main water pipe 1 to squeeze and seal the water outlet of the main drip irrigation belt 2 (such as Figure 12 As shown), the main drip irrigation belt 2 is not easy to continue to transport water to the subsequent parts, so that there is no obvious water flow through the main drip irrigation belt 2 entering the area a. Secondly, for the multiple square seats 4 on the auxiliary drip irrigation belt 3 away from the side of the main water pipe 1, except for a pair of square seats 4 on both sides of the edge, the remaining square seats 4 are all equipped with sealing members 7, and the sealing member 7 is installed in the main pipe groove 401 on the side close to the main water pipe 1 (as shown). Figure 11 and 12 As shown), the water flow in the confluence trough is not easy to reverse into the main drip irrigation belt 2, thereby effectively ensuring that there is no obvious water flow in the main drip irrigation belt 2 in area a, that is, it is impossible to irrigate area a; Moreover, since the square seats 4 on both sides of the edge can serve as the water flow intersection point of the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3, and the auxiliary drip irrigation belt 3 is not blocked, therefore, for the main drip irrigation belt 2 on the rear side of area a, although the main drip irrigation belt 2 cannot converge water flow into the confluence trough, at this time, due to the effect of water pressure (water flow can overflow through the small holes on the patch only when there is water pressure), the water flow in the auxiliary drip irrigation belt 3 will be released back into the confluence trough through the auxiliary incision 301, and then enter the main drip irrigation belt 2 through the main incision 201 (such as Figure 11 As shown), therefore, the main drip irrigation belt 2 on the rear side of area a can play a normal irrigation role.

[0029] Step 4: Local throttling: S4.1. Select a pair of auxiliary drip irrigation tapes 3 of appropriate length based on the transverse width of the local area b to be throttled, and place the pair of auxiliary drip irrigation tapes 3 on both longitudinal sides of the local area b; S4.2, repeat S2.2; S4.3. Select multiple pipe sealing members 7 and insert them into the cross members at intervals to squeeze and seal multiple main drip irrigation belts 2 flowing through area b, so that the irrigation spacing in area b is increased and flow-saving irrigation in area b is achieved (e.g. Figure 1 The blocking principle of the main drip irrigation belt 2 is the same as that in step 3, except that the number of blocked main drip irrigation belts 2 is reduced. In an adjacent pair of main drip irrigation belts 2, one main drip irrigation belt 2 irrigates normally, and the other main drip irrigation belt 2 stops irrigating, thereby increasing the irrigation spacing.

[0030] Second implementation method: This embodiment adds the following structure based on the first embodiment: Figure 13 and Figure 14 The inside of the square seat 4 is fixedly connected with an inlet pipe 91 and an outlet pipe 92, and both ends of the inlet pipe 91 and the outlet pipe 92 are connected to the confluence trough and the outside world. The ends of the inlet pipe 91 and the outlet pipe 92 that are connected to the confluence trough are both threadedly connected to one end of a hose 10, and one end of one hose 10 away from the inlet pipe 91 passes through the main incision 201 and is placed inside the main drip irrigation belt 2, and the other end of the hose 10 away from the outlet pipe 92 passes through the secondary incision 301 and is placed inside the secondary drip irrigation belt 3.

[0031] When in use, the following operations can be performed regularly: connect the end of the water inlet pipe 91 away from the hose 10 to the water outlet end of the external water pump, connect the end of the water outlet pipe 92 away from the hose 10 to the water inlet end of the external water pump, start the external water pump, and draw the water flow from the auxiliary drip irrigation belt 3 through the hose 10 and inject it into the main drip irrigation belt 2, which not only accelerates the flow rate of water in the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3, but also the water flow injected into the main drip irrigation belt 2 collides with the original water flow inside it, causing turbulence in the main drip irrigation belt 2, thereby achieving the effect of In terms of direction and flow rate, impurities are easily separated from the inner wall or small holes of the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3, which effectively alleviates the drip irrigation blockage. Moreover, since the attachment of impurities is reduced in advance, the staff can effectively judge the accumulation of impurities in the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 by opening the seal 5 and visually observing the turbidity of the water flow in the square seat 4, so as to backwash the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 in time. At the same time, due to the early desorption of impurities, the flushing time of the main drip irrigation belt 2 and the auxiliary drip irrigation belt 3 in the later period is also effectively reduced.

[0032] For the water inlet pipe 91 and the water outlet pipe 92 without the hose 10 and the external water pump installed, a threaded plug can be used to seal one end of the water inlet pipe 91 and the water outlet pipe 92 to prevent the water in the confluence trough from overflowing through the two ends.

[0033] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
