[0001] The invention relates to the technical field of self-propelled sprinkler irrigation machines, in particular to a self-propelled sprinkler irrigation machine for fields with high passability. Background Art

[0002] In modern agriculture, cultivating crops, increasing crop yields, and thereby boosting economic returns are the goals of the agricultural industry's ongoing development and advancement. This process places considerable demands on, and investment in, agricultural machinery and equipment. The demand for various types of machinery and equipment not only increases agricultural production costs, but also simplifies operations.

[0003] When existing sprinklers avoid obstacles, the sprinkler wheels usually rotate to avoid obstacles, which often causes the sprinkler to deviate from the original route and fail to spray the fields on the sprinkler route. In addition, the same field may be sprayed repeatedly. Therefore, we propose a self-propelled sprinkler for fields with high passability. Summary of the Invention

The rotating assembly is arranged through the interior of the water tank.

[0005] Preferably, the fixing rod is a cross-shaped fixing rod, and the top end of the fixing rod is connected to the third rack on a side close to the support column.

[0006] Preferably, a movable groove is provided on the side wall of the support column, and the size of the movable groove matches the size of the fixed rod, and the support column is slidably connected to the fixed rod through the movable groove provided on the side wall.

[0007] Preferably, the second connecting rod is an L-shaped connecting rod, the second rack is longitudinally arranged at the top end of the second connecting rod, and the position of the second rack corresponds to the position of the first rack.

[0008] Preferably, the sensing assembly includes a sensing block arranged at the front end of the second connecting rod, a driving rod is provided inside the sensing block, the driving rod is connected to the bottom end of the second connecting rod, and the sensing block and the driving rod are electrically connected.

[0009] Preferably, the positions of the three second moving wheels correspond to the positions of the two first moving wheels, and the initial position of the front wheel is lower than the initial position of the two first moving wheels.

[0010] Preferably: the rotating assembly includes a third rack arranged at the top end of the fixed rod, a second gear meshing with the third rack is provided at the side wall of the third rack, one end of the second gear is fixedly provided at the side wall of the water tank, and a stirring blade is fixedly provided at the other end of the second gear.

[0011] Preferably, a limit block is fixedly provided on the top of the second rack, a sliding groove matching the size of the limit block is provided on the side wall of the vehicle body, and the second rack slides in the sliding groove through the limit block provided on the top.

[0012] Preferably, a protective shell is fixedly provided on the side wall of the vehicle body, and a limiting groove is provided on the top of the protective shell.

[0013] Preferably, a pull rod is provided at the bottom end of the fixing rod and the bottom end of the first connecting rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The self-propelled sprinkler for fields with high passability, when there is an obstacle at the front end of the second moving wheel, the driving rod pushes the second connecting rod connected to the top to move upward, and the second rack moves upward until the pull rod is fully straightened, and then the second moving wheel is lifted again. At this time, the first gear rotates to drive the fixed rod to move downward, so that the first moving wheel is in contact with the ground before the second moving wheel leaves the ground. After the second moving wheel continues to rise, the first moving wheel replaces the second moving wheel to drive the irrigation machine forward, so as to avoid the situation where the traveling wheel crushes the seedlings. When encountering obstacles during spraying on the ridge, if the sprinkler wheel rotates to avoid obstacles, the sprinkler deviates from the original route and cannot spray the fields on the spraying route. The second moving wheel and the first moving wheel will not destroy the original spraying route when moving forward alternately, so as to avoid the situation where repeated spraying may occur in the same field.

[0015] This high-passability self-propelled field sprinkler has a third rack provided on the top of the fixed rod. As the fixed rod moves downward, the third rack drives the second gear to rotate, thereby stirring the mixed liquid stored in the water tank. This effectively reduces the occurrence of the mixed liquid sinking to the bottom due to long-term lack of stirring, improves irrigation efficiency, and avoids the reduction of irrigation efficiency caused by insufficient stirring of the mixed liquid during spraying.

[0016] 3. The self-propelled sprinkler for fields with high passability also effectively ensures, through the setting of the pull rod, that when the second moving wheel and the first moving wheel are alternating, the speed of the descending side is faster than the speed of the ascending side. When the first moving wheel is in contact with the ground before the second moving wheel leaves the ground, after the second moving wheel continues to rise, the first moving wheel replaces the second moving wheel to drive the irrigation machine forward, effectively ensuring the stability of the sprinkler during irrigation. After traveling a certain distance, the driving rod drives the second connecting rod to move downward, and the second moving wheel returns to the initial position to continue to drive the irrigation machine forward. The width of the second moving wheel and the first moving wheel is matched with the reserved width of the field ridge, so it is not easy to damage the field to be irrigated when moving forward, and the situation of the traveling wheels crushing the field is avoided.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-8 A self-propelled sprinkler with high passability for fields includes a vehicle body 1 and a connecting frame 4. A sprinkler head 7 is fixed to the front end of the connecting frame 4. Support columns 2 are fixed to both ends of the side walls of the vehicle body 1. Fixed rods 9 are slidably provided on the side walls of the support columns 2. Front wheels 6 are fixed to the side walls of the fixed rods 9. The front wheels 6 are fixed to the sprinkler head 7 through a telescopic rod 5 provided at the top. Two first moving wheels 10 are fixed to the bottom end of the fixed rod 9. A fixed block 12 is fixed to the bottom of the vehicle body 1. A first gear 13 is provided on the side wall of the fixed block 12. The bottom end of the fixed rod 9 is meshed with the first gear 13 through a first rack 11. It should be noted that in the initial state, the second moving wheel 18 is in contact with the ground and drives the irrigation machine forward along the ridge, while the first moving wheel 10 is retracted at one end close to the water tank 3. During movement, only the second moving wheel 18 drives the mechanism forward. At this time, if the sensing block 16 senses that there is an obstruction at the front end of the second moving wheel 18, since the sensing block 16 is electrically connected to the driving rod 23, the driving rod 23 pushes the second connecting rod 15 connected to the top to move upward, and the second rack 17 moves upward to drive the first gear 13 to rotate. The bottom of the fixed rod 9 and the first connecting rod 14 are both provided with a pull rod. After the second rack 17 moves upward to fully straighten the pull rod, the second moving wheel 18 is lifted again. The setting of the pull rod effectively ensures that when the second moving wheel 18 and the first moving wheel 10 are alternating, the speed of the descending side is faster than the speed of the ascending side.

[0021] A second connecting rod 15 is slidably provided on the side wall of the vehicle body 1. The top of the second connecting rod 15 is meshed with the first gear 13 through a second rack 17. An extension rod is provided on the side wall of the second rack 17. A first connecting rod 14 is transversely provided on the side wall of the extension rod. The side wall of the first connecting rod 14 is fixed between the extension rod and the second connecting rod 15. A sensing component is provided on the top of the second connecting rod 15. Three second moving wheels 18 are transversely provided on the side wall of the first connecting rod 14. It should be noted that since the first connecting rod 14 and the second connecting rod 15 are fixedly connected by an extension rod, when the first connecting rod 14 moves upward, it drives the first gear 13 to rotate. The other side of the first gear 13 is provided with a first rack 11 engaged with it. The first rack 11 drives the fixed rod 9 to move downward, so that the first moving wheel 10 is in contact with the ground when the second moving wheel 18 has not left the ground. After the second moving wheel 18 continues to rise, the first moving wheel 10 replaces the second moving wheel 18 to drive the irrigation machine forward, effectively ensuring the stability of the sprinkler during irrigation. After traveling a certain distance, the driving rod 23 drives the second connecting rod 15 to move downward, so that the second moving wheel 18 returns to the initial position and continues to drive the irrigation machine forward.

[0022] A water tank 3 is fixedly provided on the side wall of the support column 2 , and a rotating assembly is provided on the top end of the fixing rod 9 , which penetrates the interior of the water tank 3 .

[0023] It should be noted that after traveling a certain distance, the driving rod 23 drives the second connecting rod 15 to move downward, so that the second moving wheel 18 returns to the initial position and continues to drive the irrigation machine forward until it encounters the next obstacle and then alternates. The second moving wheel 18 and the first moving wheel 10 are not easy to damage the fields that need to be irrigated when alternating forward and will not deviate from the original route when obstacles need to be avoided, reducing the occurrence of repeated spraying. Whenever the fixed rod 9 moves downward, it cooperates with the stirring blade 22 to stir the mixed liquid in the water tank 3, reducing the occurrence of sinking to the bottom due to the mixed liquid not being stirred for a long time, thereby improving irrigation efficiency.

[0024] In an optional embodiment, the fixing rod 9 is a cross-shaped fixing rod, and the top end of the fixing rod 9 is connected to the third rack 20 on a side close to the support column 2 .

[0025] It should be noted that it is ensured that when the fixing rod 9 moves, the third rack 20 is also driven to move downward, thereby improving the stability of the device.

[0026] In an optional embodiment, a movable groove 19 is provided on the side wall of the support column 2, and the size of the movable groove 19 is adapted to the size of the fixed rod 9. The support column 2 is slidably connected to the fixed rod 9 through the movable groove 19 provided on the side wall.

[0027] It should be noted that when the fixing rod 9 is moving, the setting of the moving groove 19 effectively limits it, thereby preventing the fixing rod 9 from moving too far and causing the vehicle body to be bumpy.

[0028] In an optional embodiment, the second connecting rod 15 is an L-shaped connecting rod, the second rack 17 is longitudinally arranged at the top end of the second connecting rod 15 , and the position of the second rack 17 corresponds to the position of the first rack 11 .

[0029] It should be noted that when the first gear 13 rotates, it drives the second rack 17 to move. Since the second rack 17 is connected to the second connecting rod 15, the second connecting rod 15 is driven to move upward when the second rack 17 moves.

[0030] In an optional embodiment: the sensing assembly includes a sensing block 16 arranged at the front end of the second connecting rod 15, a driving rod 23 is provided inside the sensing block 16, the driving rod 23 is connected to the bottom end of the second connecting rod 15, and the sensing block 16 and the driving rod 23 are electrically connected.

[0031] It should be noted that when the sensing block 16 senses an obstacle at the front end, due to the electrical connection between the sensing block 16 and the driving rod 23, the driving rod 23 drives the second moving wheel 18 to move upward, so that the irrigation machine can effectively avoid the obstacle.

[0032] In an optional embodiment, the positions of the three second moving wheels 18 correspond to the positions of the two first moving wheels 10 , and the initial position of the front wheel 6 is lower than the initial position of the two first moving wheels 10 .

[0033] It should be noted that, since a telescopic rod 5 is provided at the top of the front wheel 6, when the front wheel 6 needs to move upward following the fixed rod 9, the front wheel 6 and the first movable wheel 10 are prevented from leaving the ground at the same time, thereby increasing the stability of the irrigation machine.

[0034] In an optional embodiment: the rotating assembly includes a third rack 20 arranged at the top of the fixed rod 9, and a second gear 21 meshing with the third rack 20 is provided at the side wall thereof, one end of the second gear 21 is fixedly provided at the side wall of the water tank 3, and a stirring blade 22 is fixedly provided at the other end of the second gear 21.

[0035] It should be noted that, in the process of the fixed rod 9 moving downward, since the third rack 20 is provided at the top of the fixed rod 9, the third rack 20 drives the second gear 21 to rotate, thereby stirring the mixed liquid stored in the water tank 3, effectively reducing the occurrence of the bottoming phenomenon caused by the mixed liquid not being stirred for a long time, thereby improving the irrigation efficiency and avoiding the reduction of irrigation efficiency caused by insufficient stirring of the mixed liquid during spraying.

[0036] In an optional embodiment: a limit block is fixedly provided on the top of the second rack 17, and a sliding groove matching the size of the limit block is opened on the side wall of the vehicle body 1, and the second rack 17 slides in the sliding groove through the limit block set on the top.

[0037] In an optional embodiment: a protective shell 8 is fixedly provided on the side wall of the vehicle body 1, and a limiting groove is provided on the top of the protective shell 8.

[0038] It should be noted that the provision of the protective shell 8 effectively protects the internal parts, avoiding dust accumulation caused by long-term exposure to the outside, which would reduce the service life.

[0039] In an optional embodiment, a pull rod is provided at the bottom end of the fixing rod 9 and the bottom end of the first connecting rod 14 .

[0040] Working principle: when the fields need to be irrigated, the water in the water tank 3 is transmitted to the sprinkler head 7 through the connecting frame 4, and the sprinkler head 7 sprays the fields that need to be irrigated. Since the ridges can form closed field boundaries, the irrigation water is prevented from flowing randomly and concentrated in the designated area, ensuring that each piece of farmland can be evenly irrigated, thereby improving the irrigation efficiency. In the initial state, the second moving wheel 18 is in contact with the ground and drives the irrigation machine forward along the ridge, while the first moving wheel 10 is retracted at one end close to the water tank 3. During movement, only the second moving wheel 18 drives the mechanism forward. At this time, if When the sensing block 16 senses that there is an obstruction at the front end of the second moving wheel 18, since the sensing block 16 is electrically connected to the driving rod 23, the driving rod 23 pushes the second connecting rod 15 connected to the top to move upward, and the second rack 17 moves upward to drive the first gear 13 to rotate. The bottom of the fixed rod 9 and the first connecting rod 14 are both provided with a pulling rod. After the second rack 17 moves upward to fully straighten the pulling rod, the second moving wheel 18 is pulled up again. The setting of the pulling rod effectively ensures that when the second moving wheel 18 and the first moving wheel 10 are alternating, the speed of the descending side is faster than the speed of the ascending side; Since the first connecting rod 14 and the second connecting rod 15 are fixedly connected by an extension rod, when the first connecting rod 14 moves upward, it drives the first gear 13 to rotate. The other side of the first gear 13 is provided with a first rack 11 meshed with it. The first rack 11 drives the fixed rod 9 to move downward, so that the first moving wheel 10 is in contact with the ground when the second moving wheel 18 does not leave the ground. After the second moving wheel 18 continues to rise, the first moving wheel 10 replaces the second moving wheel 18 to drive the irrigation machine forward, effectively ensuring the stability of the sprinkler during irrigation. After traveling a certain distance, the driving rod 23 drives the second connecting rod 15 to move downward, so that the second moving wheel 18 returns to the initial position and continues to drive the irrigation machine forward. The widths of the second moving wheel 18 and the first moving wheel 10 are matched with the reserved width of the ridge, so that the second moving wheel 18 and the first moving wheel 10 are not easy to damage the fields that need to be irrigated when they move forward alternately, and avoid the situation where the driving wheels crush the seedlings. If an obstacle is encountered during spraying on the ridge, the wheels of the sprinkler rotate to avoid the obstacle, causing the sprinkler to deviate from the original route and unable to spray the fields on the spraying route, and the same field may be sprayed repeatedly. The second moving wheel 18 and the first moving wheel 10 will not damage the original spraying route when they move forward alternately.

[0041] During the downward movement of the fixed rod 9, since the third rack 20 is provided at the top of the fixed rod 9, the third rack 20 drives the second gear 21 to rotate, stirring the mixed liquid stored in the water tank 3, effectively reducing the occurrence of the phenomenon of sinking to the bottom due to the mixed liquid not being stirred for a long time, improving the irrigation efficiency, and avoiding the reduction of irrigation efficiency caused by insufficient stirring of the mixed liquid during spraying.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
