Description

Technical Field

[0001] The invention relates to the technical field of irrigation and fertilization, in particular to an automatic sprinkler irrigation and drip irrigation integrated machine with a function according to vegetation coverage. Background Art

[0002] With the continuous development of agricultural production and technological advancement, the rational use of water resources and water-saving irrigation have become important issues that cannot be ignored in modern agriculture. Especially in arid and semi-arid areas, traditional irrigation methods often have problems such as wasting water resources and uneven irrigation, which affect the growth of crops and the yield of farmland. Therefore, research and development of more efficient irrigation and fertigation systems have become the key to improving agricultural productivity and water resource utilization efficiency.

[0003] Traditional irrigation and fertilization methods basically use sprinkler irrigation and flooding. The above irrigation and fertilization methods often result in uneven distribution of water and liquid fertilizer, over-irrigation or under-irrigation, which easily leads to waste of irrigation water and liquid fertilizer. Especially in arid areas or when water resources are scarce, the waste problem is more serious, thus failing to achieve the effect of agricultural water-saving irrigation. In addition, current irrigation also relies heavily on manual judgment and manual operation, which has high labor costs and is prone to management omissions due to human factors. Summary of the Invention

Then the controller controls the drive group to start, and the drive group drives the irrigation device to move to the center of the vegetation range. When the drive group moves to the designated position, if the surrounding vegetation coverage rate is high, sprinkler irrigation is used. If the surrounding vegetation coverage rate is low, drip irrigation is used, thereby improving the utilization rate of water resources and liquid fertilizers, reducing resource waste, and improving the quality of vegetation irrigation and fertilization.

[0012] Preferably, a plurality of power grooves are provided on the side wall of the irrigation body, and the plurality of power grooves are arranged around the axis of the irrigation body. A moving block is provided in the power groove, and a No. 1 motor is provided in the moving block.

[0014] Preferably, a plurality of through holes are provided on the water pipe, a bracket is provided in the through hole, a connecting rod is provided on the bracket, the connecting rod is slidingly connected to the bracket, a water-facing block is provided on the side of the connecting rod close to the inner wall of the water pipe, a blocking plate is provided on the side of the connecting rod close to the outer wall of the water pipe, and a spring is provided between the blocking plate and the bracket.

[0015] Preferably, an air tank is provided on the top of the irrigation body, an air pump is provided in the air tank, the air pump is connected to the moving cavity through a pipeline, an electromagnet is provided on the side of the rotating rod close to the sprinkler head, and a magnet is provided on the sprinkler head.

[0016] Preferably, the cross section of the side of the water receiving block facing the water flow direction is larger than the cross section of the side of the water receiving block away from the water flow direction.

[0017] When the camera transmits image information to the controller, the controller controls the drive motor to start, and the drive motor drives the crawler to move, and then the crawler drives the chassis to move, and when the chassis moves, it drives the irrigation body to move, so that the irrigation body moves toward the center of the range close to the vegetation;

[0018] When the irrigation body moves to the designated position, the controller identifies the signal transmitted by the camera. When the image signal shows a high vegetation coverage rate, the controller controls the irrigation body to irrigate and fertilize using sprinkler irrigation. Water and liquid fertilizer are mixed in the mixing chamber. The controller then controls the water pump in the mixing chamber to start and the solenoid valve in the sprinkler head to open. The water pump extracts the mixed liquid and transports it to the water pipe through the pipeline. The mixed liquid flows along the water pipe to the moving rod and is finally sprayed out through the sprinkler head.

[0019] When the mixed liquid is sprayed out from the sprinkler head, the controller controls the rotating motor in the driving group to start, and the driving shaft of the rotating motor drives the irrigation body to rotate. When the irrigation body rotates, it drives the fixed ring to rotate. During the rotation of the fixed ring, it drives several irrigation rods to rotate, and then the sprinkler head is in a state of rotating sprinkling irrigation. At the same time, the controller controls the No. 1 motor in the moving block to start, and the driving shaft of the No. 1 motor drives the transmission wheel to rotate. During the rotation of the transmission wheel, it contacts the inner wall of the power groove, so that the transmission wheel drives the moving block to move vertically up and down along the power groove. During the movement of the moving block, it drives the pull rod to move, and when the pull rod moves, it pulls the rotating rod to rotate. The rotating rod rotates around the fixed axis, so that the rotating rod moves from the placement groove to the rotating groove. The rotating rod slides in the sliding groove through the slider, thereby realizing the conditions of the irrigation rod spraying angle, so that when the ground is undulating, the mixed liquid can cover the vegetation behind the undulating ground through the spraying angle, thereby improving the quality of vegetation irrigation and fertilization;

[0020] Since the water pipe is provided with a plurality of through holes, and the mixed liquid in the water pipe is pressurized by the water pump and moves toward the sprinkler head at high speed, the flow rate in the water pipe is relatively fast. When the high-speed mixed liquid flows through the water inlet block, since the cross-section of the side of the water inlet block facing the water flow direction is larger than the cross-section of the side of the water inlet block away from the water flow direction, the mixed liquid drives the water inlet block to move toward the side close to the axis of the water pipe. When the water inlet block moves, it drives the connecting rod to move, and the connecting rod drives the blocking plate to move, so that the blocking plate fits and seals with the through hole, thereby preventing the mixed liquid in the water pipe from leaking through the through hole.

[0021] When the vegetation coverage rate reflected by the image signal is low, the controller controls the irrigation body to use drip irrigation for irrigation and fertilization. Before irrigation, the rotating motor in the sprinkler head and the drive group is in a closed state, and the electromagnet on the rotating rod is energized. The electromagnet attracts the magnet on the sprinkler head, causing the sprinkler head to be adsorbed on the rotating rod. Then the controller controls the air pump in the air storage tank to start, and the air pump draws outside air and delivers it to the mobile cavity through a pipeline. After a large amount of pressurized gas is delivered to the mobile cavity, the air pressure in the mobile cavity rises. When the air pressure in the mobile cavity reaches the set value, the controller controls the electromagnet to cut off the power, and then the sprinkler head loses the magnetic influence of the electromagnet, and then the sprinkler head and the mobile cavity are The movable rod moves to the side away from the placement slot under the action of the air pressure in the moving chamber, so that the sprinkler head is thrown toward the vegetation. When the movable rod moves, it drives the water pipe to move. When the water pipe moves, it drives the reel to rotate, so that the reel unwinds the water pipe. When several sprinkler heads fall to the ground, the controller controls the water pump to start, and the mixed liquid is immediately transported to the water pipe under the action of the water pump. Since the sprinkler head is in a closed state, the mixed liquid cannot be quickly transported to the outside world, and the flow rate of the mixed liquid in the water pipe is reduced. At this time, the elastic force of the spring arranged between the blocking plate and the bracket is greater than the force of the water flow on the water-facing block, so that the through hole connects the outside world and the water pipe, and the mixed liquid in the water pipe can flow to the outside world through the through hole, thereby achieving the effect of drip irrigation of vegetation.

[0022] When the drip irrigation operation is completed, the controller controls the No. 2 motor on the reel to start, and the drive shaft of the No. 2 motor drives the reel to rotate, and the reel then reels the water pipe and reels the water pipe into the reel chamber.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The vegetation coverage rate of the irrigation area is identified by the camera, so that the irrigation method (drip irrigation or sprinkler irrigation) can be adjusted. When the vegetation coverage rate is high, the mixed liquid is directly sprayed out through the sprinkler head, and the moving block is used to drive the irrigation rod to slide in the rotating groove, thereby changing the sprinkler head's spraying angle. In this way, on the undulating ground, the vegetation on the side away from the irrigation body can be irrigated, thereby increasing the vegetation irrigation coverage rate and thus improving the quality of vegetation irrigation and fertilization.

[0025] 2. When the vegetation coverage rate is low, the gas is transported into the mobile cavity, so that the air pressure in the mobile cavity rises, and then the mobile rod and the sprinkler head are pushed to the side away from the irrigation body, so that the mobile rod drives the water pipe to move, and the water pipe moves toward the vegetation. After the mixed liquid falls to the ground in the water pipe, it flows to the vegetation through the through hole, achieving a drip irrigation effect, avoiding sprinkler irrigation in areas with low vegetation coverage, resulting in waste of water resources and liquid fertilizer, thereby improving resource utilization.

[0045] Working principle of the present invention:

[0046] Water and liquid fertilizer are delivered to the irrigation body 21. Then, the controller starts the camera 22, which monitors the surrounding environment and converts the surrounding image signal into an electrical signal and transmits it to the controller. The controller recognizes the transmitted signal and calculates the vegetation coverage rate of the surrounding environment, and then selects the drip irrigation or sprinkler irrigation method.

[0047] When the camera 22 transmits image information to the controller, the controller controls the drive motor to start, and the drive motor drives the crawler 12 to move, and then the crawler 12 drives the chassis 11 to move, and when the chassis 11 moves, it drives the irrigation body 21 to move, so that the irrigation body 21 moves toward the center of the range close to the vegetation;

[0048] After the irrigation body 21 moves to the designated position, the controller identifies the signal transmitted by the camera 22. When the image signal indicates a high vegetation coverage, the controller controls the irrigation body 21 to perform irrigation and fertilization by means of sprinkler irrigation. Water and liquid fertilizer are mixed in the mixing chamber 33. The controller then controls the water pump in the mixing chamber 33 to start and the solenoid valve in the sprinkler head 281 to open. The water pump extracts the mixed liquid and transports it to the water pipe 29 through a pipeline. The mixed liquid flows along the water pipe 29 to the movable rod 28 and is finally sprayed out through the sprinkler head 281.

[0049] When the mixed liquid is sprayed out from the sprinkler head 281, the controller controls the rotating motor in the driving group 1 to start, and the driving shaft of the rotating motor drives the irrigation body 21 to rotate. When the irrigation body 21 rotates, it drives the fixed ring 23 to rotate. During the rotation of the fixed ring 23, it drives several irrigation rods 25 to rotate, and then the sprinkler head 281 is in a state of rotating sprinkling. At the same time, the controller controls the No. 1 motor in the moving block 31 to start, and the driving shaft of the No. 1 motor drives the transmission wheel to rotate. During the rotation of the transmission wheel, it contacts the inner wall of the power groove 30, so that the transmission wheel drives the moving block 31 to move vertically up and down along the power groove 30. During the movement of the moving block 31, it drives the pull rod 32 to move. When the pull rod 32 moves, it pulls the rotating rod 27 to rotate. The rotating rod 27 rotates around the fixed axis, so that the rotating rod 27 moves from the placement groove 24 to the rotating groove 26. The rotating rod 27 slides in the sliding groove 261 through the slider, thereby realizing the conditions of the irrigation angle of the irrigation rod 25, so that when the ground is undulating, the mixed liquid can cover the vegetation behind the undulating ground through the irrigation angle;

[0050] Since the water pipe 29 is provided with a plurality of through holes 291, the mixed liquid in the water pipe 29 is pressurized by the water pump and moves at high speed toward the sprinkler head 281, resulting in a relatively fast flow rate in the water pipe 29. When the high-speed mixed liquid flows through the water inlet block 293, since the cross-section of the side of the water inlet block 293 facing the water flow direction is larger than the cross-section of the side of the water inlet block 293 away from the water flow direction, the mixed liquid drives the water inlet block 293 to move toward the side close to the axis of the water pipe 29. When the water inlet block 293 moves, it drives the connecting rod 292 to move, and the connecting rod 292 drives the blocking plate 294 to move, so that the blocking plate 294 fits and seals against the through holes 291, thereby preventing the mixed liquid in the water pipe 29 from leaking through the through holes 291.

[0051] When the vegetation coverage reflected by the image signal is low, the controller controls the irrigation body 21 to use drip irrigation for irrigation and fertilization. Before irrigation, the sprinkler head 281 and the rotating motor in the drive group 1 are in a closed state, and the electromagnet on the rotating rod 27 is in a powered state. The electromagnet attracts the magnet on the sprinkler head 281, so that the sprinkler head 281 is adsorbed on the rotating rod 27. Then the controller controls the air pump in the air storage tank to start. The air pump draws outside air and transports it to the mobile chamber 271 through a pipeline. After a large amount of pressurized gas is transported to the mobile chamber 271, the air pressure in the mobile chamber 271 rises. When the air pressure in the mobile chamber 271 reaches the set value, the controller controls the electromagnet to cut off the power, and then the sprinkler head 281 loses the magnetic influence of the electromagnet, and then the sprinkler head 281 and the mobile rod 28 move. Under the action of the air pressure in the cavity 271, it moves to the side away from the placement groove 24, so that the sprinkler head 281 is projected toward the vegetation. When the moving rod 28 moves, it drives the water pipe 29 to move. When the water pipe 29 moves, it drives the reel 35 to rotate, so that the reel 35 unwinds the water pipe 29. When several sprinkler heads 281 fall to the ground, the controller controls the water pump to start, and the mixed liquid is immediately transported to the water pipe 29 under the action of the water pump. Since the sprinkler heads 281 are in a closed state, the mixed liquid cannot be quickly transported to the outside world, and the flow rate of the mixed liquid in the water pipe 29 is reduced. At this time, the elastic force of the spring provided between the blocking plate 294 and the bracket is greater than the force of the water flow on the water-facing block 293, so that the through hole 291 connects the outside world with the water pipe 29, and the mixed liquid in the water pipe 29 can flow to the outside world through the through hole 291, thereby achieving the effect of drip irrigation of vegetation;

[0052] When the drip irrigation operation is completed, the controller controls the second motor on the reel 35 to start, and the drive shaft of the second motor drives the reel 35 to rotate. The reel 35 then reels the water pipe 29 and reels the water pipe 29 into the reel chamber 34.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
