However, due to its large width, when the equipment is not in use, it occupies a large area and requires a large farm warehouse for storage, which is a waste of land resources. At the same time, the existing irrigation method of the intelligent irrigation integrated machine for unmanned farms is relatively single, and it can only irrigate single crops, unable to meet the irrigation needs of different crops, and its applicability is poor.

[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0032] Refer to Figure 1 , an intelligent irrigation all-in-one machine for unmanned farms, including an upright frame 3. A rear side of the upright frame 3 is provided with an irrigation mechanism 2 for irrigating farm crops, and a front side of the upright frame 3 is provided with a traction mechanism 1 for driving the irrigation mechanism 2 to move among farm crops.

[0033] Refer to Figure 1 and Figure 5, the irrigation mechanism 2 includes a horizontal main pipe 24 movably arranged at the rear side of the vertical frame 3 and distributed in the left-right direction. A height adjustment component 22 for controlling the up-and-down movement of the horizontal main pipe 24 is arranged inside the vertical frame 3. Telescopic components 21 for widening the irrigation range are respectively arranged at the left and right ends of the horizontal main pipe 24. The telescopic component 21 includes a multi-stage telescopic pipe 214. The inner section of the multi-stage telescopic pipe 214 is sleeved inside the horizontal main pipe 24. Vertical branch pipes 25 are communicated with the outer ends of each section of the multi-stage telescopic pipe 214, the left and right ends of the horizontal main pipe 24, and the lower side of its central position. A number of sprinkler sub-heads 252 with the spray nozzles facing the front side are equidistantly installed on the vertical branch pipes 25. Irrigation main heads 251 are symmetrically arranged at the left and right ends of the lower part of the vertical branch pipes 25. A conversion component 27 for converting the water outlet mode is jointly arranged inside and outside the vertical branch pipes.

[0034] Refer to Figure 1 and Figure 2 , the traction mechanism 1 includes a frame 12 fixedly connected to the bottom of the vertical frame 3. A number of brackets 13 are fixedly connected to the bottom of the frame 12. Traveling wheels 14 are installed on the brackets 13. An installation opening is formed inside the frame 12, and a pipe laying component 11 for arranging the water pipes for pumping water along the way is arranged.

[0035] By using the irrigation mechanism 2 and the traction mechanism 1 in cooperation, the automatic irrigation and sprinkler irrigation of various crops on the farm can be realized.

[0036] Refer to Figure 5 , the telescopic component 21 further includes a hinged frame group 211 arranged on the upper side of the multi-stage telescopic pipe 214. The hinged frame group 211 is successively hinged by a plurality of hinged frames connected in an X shape and a hinged frame with the head and tail ends connected in a V shape. The central hinge rods of the hinged frame group 211 are successively fixedly connected to the outer ends of each section of the multi-stage telescopic pipe 214 and the upper side of the outer end of the horizontal main pipe 24. Fixed seats 213 are symmetrically fixedly connected to the left and right sides of the horizontal main pipe 24. An electric push rod 212 is fixedly connected to the fixed seat 213. The output end of the electric push rod 212 is fixedly connected to the central hinge rod of an X-shaped connected hinged frame close to the horizontal main pipe 24.

[0037] During specific operation, the central hinge rod of an X-shaped connected hinged frame close to the horizontal main pipe 24 is controlled to move in the horizontal direction through the electric push rod 212. During the movement, each section of the multi-stage telescopic pipe 2 is driven by the central hinge rods of the hinged frame group 211 to synchronously extend, so as to adjust the horizontal extension range of the horizontal main pipe 24, and the overall floor area of the instrument can be effectively saved when it is shortened to the minimum range.

[0038] Refer to Figure 1 and Figure 4, the height adjustment component 22 includes a lead screw 222 rotatably connected inside the vertical frame 3, and guide rods 223 symmetrically and fixedly connected to the inside of the vertical frame 3 on the left and right. A moving seat 224 is threadedly connected to the lead screw 222, and the moving seat 224 is also slidably connected to the left and right guide rods 223. The horizontal main pipe 24 is rotatably connected to the front side of the moving seat 224. The upper end of the lead screw 222 extends outside the vertical frame 3 and is fixedly connected to the output end of the second motor 221, and the second motor 221 is fixedly connected to the top of the vertical frame 3.

[0039] During specific operation, the second motor 221 is used to control the rotation of the lead screw 222, and the lead screw 222 drives the moving seat 224 to move up and down along the guide rod 223, thereby driving the horizontal main pipe 24 to move up and down through the moving seat 224, and adaptively adjusting the irrigation height according to the irrigation position required by the crops.

[0040] Refer to Figure 6 , a distance adjustment component 26 for controlling the distance between the two is arranged between the two irrigation main heads 251. The distance adjustment component 26 includes a T-shaped mounting seat 262 fixedly sleeved on the lower side of the vertical water pipe. An electric push rod three 261 is fixedly connected to the upper side of the T-shaped mounting seat 262. The output end of the electric push rod three 261 faces downward and is fixedly connected to a double-sided rack 264. Both sides of the double-sided rack 264 are meshed with drive gears 263. The drive gears 263 are rotatably connected to the T-shaped mounting seat 262 through rotating rods. The rotating rods extend outward and are fixedly connected to rotating arms 265. One end of the rotating arm 265 away from the drive gear 263 is hinged with a movable sleeve 266. The movable sleeve 266 is slidably sleeved on the connecting hose 268. One end of the connecting hose 268 is communicated with the vertical branch pipe 25, and the other end of the connecting hose 268 is communicated with the irrigation main head 251. A first spring 267 is sleeved on a section of the connecting hose 268 between the irrigation main head 251 and the movable sleeve 266. Both ends of the first spring 267 are fixedly connected to the irrigation main head 251 and the movable sleeve 266 respectively.

[0041] During specific operation, the electric push rod three 261 is used to control the movement of the double-sided rack 264, the double-sided rack 264 controls the rotation of the drive gears 263, and the drive gears 263 drive the rotating arms 265 to rotate to control the movable sleeve 266 to drive the two connecting hoses 268 to change the forking angle, thereby adjusting the irrigation distance of the irrigation main head 251. Since different crops have different abilities to withstand the impact of water flow, keeping the irrigation main head 251 away from the crops can avoid the direct impact of water flow on crops with weak impact resistance. For crops with strong impact resistance, direct contact irrigation can be carried out.

[0042] Refer to Figure 6 、 Figure 7 and Figure 8, the conversion component 27 includes a sliding tube 279 that is tightly and slidably connected within the vertical branch pipe 25. The sliding tube 279 is provided with a first set of perforations that correspond one-to-one with a number of sub-sprinkler heads 252. The lower side of the sliding tube 279 is also provided with a second set of perforations that correspond one-to-one with the installation positions of the connecting hoses 268 on both sides. The vertical distance between the lowermost first perforation and the second perforation is greater than the vertical distance between the lowermost sub-sprinkler head 252 and the connecting hose 268. The bottom of the sliding tube 279 is closed and integrally and fixedly connected to a movable seat 272. The movable seat 272 slidably penetrates the bottom of the vertical branch pipe 25. A second spring 271 is installed between the bottom wall of the movable seat 272 and the bottom of the vertical branch pipe 25. A contact roller 273 is rotatably installed at the bottom of the movable seat 272. The contact roller 273 is in rolling contact with a cam 275. The cam 275 is provided with a protrusion 277. When the vertical branch pipe 25 is in a vertical state, the protrusion 277 points in the same direction as the sub-sprinkler head 252. A stop weight ball 276 is also fixedly connected to the cam 275. The stop weight ball 276 is perpendicularly distributed with respect to the protrusion 277. A connecting pin 274 is fixedly connected to the rotation center of the cam 275. Both ends of the connecting pin 274 are rotatably connected to a support plate 278. The two support plates 278 are fixedly connected to the bottom of the T-shaped mounting seat 262. A rotating pipe component 23 for controlling its rotation is provided in the middle of the horizontal main pipe 24. A locking component 28 for locking the sliding tube 279 when the vertical branch pipe 25 is in a horizontal state is provided on one of the support plates 278; the rotating pipe component 23 includes a rotating gear 231 fixedly connected to the middle position of the horizontal main pipe 24. The outer periphery of the rotating gear 231 is meshed with a vertically distributed moving rack 232. The upper end of the moving rack 232 is fixedly connected to the output end of the second electric push rod 233. The second electric push rod 233 is fixedly connected to the moving seat 224 through a fixing bracket.

[0043] During specific operation, when the vertical branch pipe 25 is in the vertical state, the second perforation of the sliding pipe 279 corresponds to the installation position of the connecting hose 268, and the first perforation is offset from the position of the sprinkler sub-head 252. The second spring 271 is in an unloaded state. When watering, water flows out from the watering main head 251 for irrigation. The electric push rod 233 controls the downward movement of the moving rack 232 to drive the rotation of the rotating gear 231, which controls the horizontal main pipe 24 to rotate 90°. This converts the vertical branch pipe 25 to the horizontal state. The stop weight ball 276 can keep the cam 275 in its original state, and the contact roller 273 will roll around the cam 275. Affected by the change in the distance between the rotation center axes of the cam 275 and the contact roller 273, the sliding pipe 279 will move upward along the vertical branch pipe 25 and compress the second spring 271. After the horizontal main pipe 24 rotates 90°, the installation positions of the second perforation and the connecting hose 268 are offset, and the first perforation corresponds to the position of the sprinkler sub-head 252. When watering, water flows out from the sprinkler sub-head 252 for sprinkler irrigation. The vertical branch pipe 25 is in the horizontal state for sprinkler irrigation, which can save water. At the same time, the same position can be repeatedly sprinkler-irrigated multiple times, and it can ensure that the crops fully absorb water. When the vertical branch pipe 25 is in the horizontal state, the water flow inside the sliding pipe 279 has a certain water pressure, and the locking component 28 limits the sliding pipe 279 to ensure that the sliding pipe 279 does not shift and affect the position correspondence between the first perforation and the sprinkler sub-head 252.

[0044] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS.

[0045] During specific operation, water is pumped by the pressure pump 16, and the water is transported by the water pipe 112 until it is transported to the horizontal main pipe 24. The front driving wheel 14 is controlled to rotate by the motor 17 to drive the entire device. At the same time, the central pipe 115 is synchronously driven by the motor 17 to rotate to lay the water pipe 112 along the way, so as to maintain continuous water supply.

[0046] See Figure 2 and Figure 3 A reinforcing plate 15 is fixedly connected between the left and right brackets 13 , and a U-shaped bracket 151 is fixedly connected to the upper middle side of the reinforcing plate 15 , and the tail section of the water pipe 112 slides through the center of the U-shaped bracket 151 .

[0047] During specific operation, the left and right side brackets 13 are supported on the inside by the reinforcing plate 15 to increase the structural strength of the two brackets 13 , and the water pipe 112 is arranged and limited by the U-shaped bracket 151 .

[0048] See Figure 5 and Figure 7 Sealing rings are installed at the connection position between the multi-stage telescopic pipe 214 and the horizontal main pipe 24, the connection position between two adjacent sections of the multi-stage telescopic pipe 214, and the connection position between the movable seat 272 and the bottom of the vertical branch pipe 25.

[0049] During specific work, sealing rings are used to seal each connected position to avoid water leakage.

[0050] During use: S1: The front traveling wheel 14 is controlled to rotate by the motor 17 to drive the entire device. At the same time, the central pipe 115 is synchronously driven by the motor 17 to rotate to lay the water pipe 112 along the way. Water is pumped by the pressure pump 16 and transported by the water pipe 112 until it is transported to the horizontal main pipe 24.

[0051] S2: During normal use, the vertical branch pipe 25 is in a vertical state, the second perforation of the sliding tube 279 corresponds to the installation position of the connecting hose 268, the first perforation is staggered with the position of the sprinkler sub-head 252, and the second spring 271 is in a stress-free state. When water is released, water flows out from the main irrigation head 251 for irrigation.

[0052] S3: When it is necessary to change the irrigation method, the electric push rod two 233 controls the downward movement of the moving rack 232 to drive the rotation of the rotating gear 231, which controls the rotation of the horizontal main pipe 24 by 90°, so that the vertical branch pipe 25 is converted to a horizontal state. The stop weight ball 276 can keep the cam 275 in its original state, and the contact roller 273 will roll around the cam 275. Affected by the change in the distance between the rotation center axes of the cam 275 and the contact roller 273, the sliding pipe 279 will move upward along the vertical branch pipe 25 and compress the spring two 271. After the horizontal main pipe 24 rotates 90°, the installation positions of the second perforation and the connecting hose 268 are staggered, and the first perforation corresponds to the position of the sprinkler sub-head 252. When discharging water, the water source flows out from the sprinkler sub-head 252 for sprinkler irrigation.

[0053] S4: When it is necessary to change the irrigation height, the motor two 221 controls the rotation of the lead screw 222. The lead screw 222 drives the moving seat 224 to move up and down along the guide rod 223, so as to drive the horizontal main pipe 24 to move up and down through the moving seat 224, and adaptively adjust the irrigation height according to the irrigation position required by the crops. When it is necessary to change the irrigation distance, the electric push rod three 261 controls the movement of the double-sided rack 264. The double-sided rack 264 controls the rotation of the drive gear 263. The drive gear 263 drives the rotation of the rotating arm 265 to control the movable sleeve 266 to drive the two connecting hoses 268 to change the forking angle, so as to adjust the irrigation distance of the irrigation main head 251.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc., made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
