Description

A drip irrigation device and drip irrigation system based on smart agriculture Technical Field

[0001] The present invention relates to the technical field of drip irrigation equipment, and more specifically, to a drip irrigation device and a drip irrigation system based on smart agriculture. Background Art

[0002] Drip irrigation is a water-saving irrigation method, achieving a water utilization rate of up to 95%. Compared to sprinkler irrigation, drip irrigation offers greater water conservation and yield-increasing benefits. It can also be combined with fertilization to more than double fertilizer efficiency. It is suitable for irrigating fruit trees, vegetables, cash crops, and greenhouses, and can also be used to irrigate field crops in drought-scarce areas.

[0010] Furthermore, a support shaft is rotatably connected between the two ends of the extrusion block on one side close to the water storage bag, and a rotating wheel is provided on the support shaft.

[0011] Furthermore, the support shaft is rotatably connected to the rotating wheel, and a receiving groove is provided at one end of the rotating wheel.

Teeth are distributed on the upper side of the driving groove, and the extrusion gear () is engaged with the teeth ().

[0013] Furthermore, a driving shaft is rotatably provided between the upper and lower ends of the water storage layer, a driving guide rail is fixed between the upper and lower ends of the water storage layer, a movable sleeve and a driving gear are sleeved on the driving shaft, one end of the movable sleeve is rotatably connected to the driving gear, one side of the movable sleeve is slidably connected to the driving guide rail, the driving shaft is threadedly connected to the movable sleeve, a slot is provided between the two ends of the driving shaft, a block is fixed on the inner side of the driving gear, the block is stuck in the slot, the driving gear is meshed with the rack, a driver is fixed on the upper side of the box body, and the output shaft of the driver is fixed to the driving shaft.

[0019] The beneficial effects of the present invention are:

[0020] By placing the box at a high point, it is possible to use water pressure for drip irrigation;

[0036] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0038] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0039] As shown in Figures 1-7, the present application provides a drip irrigation device based on smart agriculture, including a box body 1, in which a partition 11 is fixed. The partition 11 separates the box body 1 into two layers, namely a water storage layer 12 and a protective layer 13.

[0040] A water bag 2 is positioned within the water reservoir 12. A water outlet pipe 21 is secured to the underside of the bag 2, with the lower end of the pipe extending from the bottom of the housing 1. The upper end of the bag 2 is open, and a bracket 121 is secured to the top of the inner surface of the water reservoir 12. The edge of the upper opening of the bag 2 is secured to the bracket 121. A water level sensor 122 and a water inlet 123 are located on the upper side of the bag 2, corresponding to the location of the upper opening.

[0041] It is understandable that the water outlet pipe 21 is connected to an external drip irrigation pipe (not shown), and the water inlet 123 is connected to an external water supply device (not shown).

[0042] A plurality of extrusion blocks 3 are distributed from bottom to top on one side of the partition 11 close to the water storage bag 2. Extrusion guide rails 124 corresponding to the positions of the extrusion blocks 3 are provided on both sides of the water storage layer 12, and the two ends of the extrusion block 3 are respectively slidably connected to one extrusion guide rail 124.

[0043] A support shaft 31 is rotatably connected between the two ends of the squeezing block 3, near the water storage bag 2. A rotating wheel 32 is rotatably mounted on the support shaft 31. A receiving slot 321 is provided at one end of the rotating wheel 32. Several protrusions 311 are fixed to the circumferential outer wall of the support shaft 31 within the receiving slot 321. Several receiving holes 322 are distributed along the circumferential inner wall of the receiving slot 321. Each of these holes is equipped with a movable block 323. An elastic member 324 is connected between the bottom of the receiving hole 322 and the movable block 323. In this embodiment, the elastic member 324 is a spring.

[0044] The upper side of the extrusion guide rail 124 is provided with a driving groove 125 corresponding to the position of the support shaft 31. The two ends of the support shaft 31 are respectively extended into the driving groove 125 on one side and an extrusion gear 312 is fixed thereon. The upper side of the driving groove 125 is distributed with teeth 126, and the extrusion gear 312 is engaged with the teeth 126.

[0045] Guide shafts 33 are fixed to both ends of the extrusion block 3 on the side away from the water storage bag 2. A rack 34 is also fixed to the side of the extrusion block 3 away from the water storage bag 2. A shaft sleeve 111 corresponding to the position of the guide shaft 33 and two clamping plates 112 corresponding to the position of the rack 34 are fixed to the partition 11. The shaft sleeve 111 is mounted on the guide shaft 33, and the clamping plates 112 clamp the rack 34. One end of the guide shaft 33 and the rack 34 both pass through the partition 11 and extend into the protective layer 13. A spring piece 113 corresponding to the position of the rack 34 is fixed to the partition 11, and one side of the spring piece 113 is engaged with the rack 34.

[0046] A driving shaft 4 is rotatably provided between the upper and lower ends of the water storage layer 12 , and a driving guide rail 41 is fixed between the upper and lower ends of the water storage layer 12 .

[0047] A movable sleeve 42 and a driving gear 43 are sleeved on the driving shaft 4. One end of the movable sleeve 42 is rotatably connected to the driving gear 43. One side of the movable sleeve 42 is slidably connected to the driving guide rail 41. The driving shaft 4 is threadedly connected to the movable sleeve 42.

[0048] A clamping groove 44 is provided between the two ends of the driving shaft 4. A clamping block 45 is fixed to the inner side of the driving gear 43. The clamping block 45 is clamped into the clamping groove 44. The driving gear 43 is meshed with the rack 34.

[0049] A driver 46 is fixed to the upper side of the housing 1 . In this embodiment, the driver 46 is a motor, and an output shaft of the driver 46 is fixed to the driving shaft 4 .

[0050] The box body 1 is supported by an external bracket (not shown), which supports the box body 1 at a high place. The water pressure generated by the height causes the water in the water storage bag 2 to flow to the drip irrigation pipe through the outlet pipe 21 for drip irrigation.

[0051] The water level sensor 122 is used to detect the water level in the water storage bag 2 in real time. When the water level in the water storage bag 2 is too low, the driver 46 is activated to rotate the drive shaft 4. Through the threaded connection between the drive shaft 4 and the movable sleeve 42, and the drive guide 41 preventing the movable sleeve 42 from rotating, the movable sleeve 42 drives the drive gear 43 to move upward from the lower end of the drive shaft 4. The card block 45 is pushed through the card slot 44, which allows the drive gear 43 to rotate while moving upward.

[0052] Because the driving gear 43 is meshed with the rack 34, the driving gear 43 rotates to push the squeezing blocks 3 toward the water bag 2, thereby squeezing the water bag 2. When one squeezing block 3 is extended to its limit, as the driving gear 43 moves upward, the driving gear 43 separates from the rack 34 on that squeezing block 3 and meshes with the rack 34 on the squeezing block 3 above it, thereby allowing the squeezing blocks 3 to extend one by one from bottom to top.

[0053] By extending the squeezing block 3, the squeezing block 3 can squeeze and deform the lower end of the water storage bag 2. At this time, the volume of the lower side of the water storage bag 2 will decrease, thereby causing the water level inside the water storage bag 2 to rise until the water level inside the water storage bag 2 reaches a suitable height. The driver 46 stops running, thereby achieving the effect of maintaining the water level, thereby maintaining the water pressure and stabilizing the drip irrigation speed.

[0054] The spring piece 113 is engaged with the rack 34 , so that there is a certain resistance to the movement of the extrusion block 3 , which can prevent the extrusion block 3 from being pushed back by water pressure after the driving gear 43 is separated from the rack 34 .

[0055] During the movement of the squeezing block 3, the squeezing gear 312 meshes with the teeth 126, causing the support shaft 31 to rotate. The engagement between the protrusion 311 and the movable block 323 causes the rotating wheel 32 to rotate along with the support shaft 31. When the water storage bag 2 contacts the rotating wheel 32, the rotating wheel 32 rotates, causing the water storage bag 2 to flip toward the upper side of the rotating wheel 32, thereby preventing the water storage bag 2 from being squeezed and damaged between the two squeezing blocks 3.

[0056] When the water storage bag 2 cannot continue to flip toward the upper side of the rotating wheel 32, the rotating wheel 32 will encounter resistance. At this time, the continued rotation of the support shaft 31 will cause the protrusion 311 and the movable block 323 to be squeezed. Through the elastic deformation of the elastic member 324, the movable block 323 will shrink into the accommodating hole 322, thereby preventing the rotating wheel 32 from continuously pulling the water storage bag 2, and further preventing the water storage bag 2 from being pulled and damaged.

[0057] When the driver 46 drives the driving shaft 4 to reverse, the extended extrusion blocks 3 will be reset one by one from top to bottom.

[0058] Since the extrusion blocks 3 extend one by one from bottom to top, it can be ensured that the upper part of the water surface will shrink last, thereby slowing down the falling speed of the water surface, and further reducing the starting frequency of the driver 46, saving power while avoiding damage to the driver 46 due to frequent starting and stopping.

[0059] This mode of operation allows drip irrigation to be carried out without a water pump.

[0060] A drip irrigation system based on smart agriculture includes a control terminal. Upper and lower contacts corresponding to the positions of a movable sleeve 42 are provided at the upper and lower ends of a water storage layer 12. When the movable sleeve 42 moves to the uppermost end, it contacts the upper contact. When the movable sleeve 42 moves to the lowermost end, the drive gear 43 contacts the lower contact. The upper and lower contacts, water level sensor 122, driver 46, water supply equipment, and drip irrigation pipes are all connected to the control system.

[0061] The control end is provided with an irrigation system and a water supply system, and the control end is provided with a required water level height range.

[0062] When the irrigation system is running, the water supply equipment is closed and the drip irrigation pipe is opened. When the water level is within the set range;

[0063] When the water level is higher than the set range, the control end controls the driver 46 to reverse, causing the movable sleeve 42 to descend. When the lower contact is triggered, if the water level is still higher than the set range, an alarm is issued.

[0064] When the water level is lower than the set range, the control end controls the driver 46 to rotate forward, causing the movable sleeve 42 to rise. When the upper contact is triggered, if the water level is still lower than the set range, the water replenishment system is operated.

[0065] When the water supply system starts to operate, the drip irrigation pipe is closed, and the control end controls the driver 46 to reverse, so that the movable sleeve 42 descends until the lower contact is triggered. Then the water supply equipment is started, and when the water level reaches the set range, the irrigation system starts to operate.
