[0011] 1. The rice seedling spraying device is provided with an adjustable adjusting swing arm. After two mounting bases are separated from each other and mounted on the inner bottom surface of the mounting cross plate, the two adjusting swing arms are respectively inserted into the openings on the top of the mounting bases and locked and mounted by bolts, the telescopic support rod is mounted in the mounting cavity preset inside the adjusting swing arm, and then the water delivery pipeline at the tail of the spraying component is connected with the shunt pipe on the output end of the water pump through the connecting port. After the device is installed, when spraying the rice seedlings, the water pump is started to push the pushing cart to move. After the two adjusting swing arms extend out of the limit card slots, the bottoms touch the surface of the limit card slots. The water pump drives the liquid in the storage tank to be transported to the adjusting swing arm through the delivery pipe and sprayed out through the spray hole at the bottom of the adjusting swing arm. When performing the spraying operation, the seedlings on both sides of the cart can be sprayed only by pushing the cart, so that the manual operation amount is greatly reduced, the user's fatigue is reduced, and the operation can be performed for a long time.

[0012] 2. The rice seedling spraying device is provided with a telescopic support rod for supporting and positioning. After the adjusting swing arm is installed, the telescopic support rod is installed between two locking holes opened inside the installation cavity. The length of the telescopic support rod is adjusted to make the telescopic support rod retract into the inside of the installation cavity. After the two adjusting swing arms are installed above the mounting cross plate, in a normal state, the two adjusting swing arms are parallel to the surface of the pushing cart. When it is necessary to adjust the spray range to spray seedlings farther away, the knob on the surface of the telescopic support rod is adjusted to pull up the telescopic support rod. The entire adjusting swing arm is lifted by the telescopic support rod against the inner bottom surface of the mounting cross plate, so that the spraying range of the spraying part becomes wider. During the movement of the entire device, the seedlings on both sides of the pushing cart can be covered in a large range by adjusting the deployment angle of the adjusting swing arm, thereby improving the spraying efficiency.

The mounting cross plate 6 is a plate of a rectangular structure, and the upper surface of the mounting cross plate 6 is provided with two position corresponding limit slots 8, and a water pump 9 is arranged and installed below the supporting columns 5, and the input end of the water pump 9 is connected to the interior of the material storage tank 4, and the inner bottom surface of the mounting cross plate 6 is provided with a connecting port 7 connected to the lower surface of the mounting cross plate 6, and the inner bottom surface of the mounting cross plate 6 is fixedly provided with two mounting bases 10 at positions far away from each other.

[0020] The interior of the two mounting bases 10 is provided with locking sockets 12 for bolts to pass through, and the interior of the two mounting bases 10 is movably provided with an adjusting swing arm 11 with a long plate structure. A through hole is provided in the interior of the adjusting swing arm 11 corresponding to one end of the mounting base 10. The end of the adjusting swing arm 11 is inserted between the two locking sockets 12 and then locked with bolts.

[0021] A spray component 13 is embedded and installed inside the ends of the two adjusting swing arms 11 that are away from each other. A spray hole for spraying fertilizer is opened on the lower surface of the spray component 13. The water supply pipe of the spray component 13 is connected and installed with the output port of the water pump 9. After starting the water pump 9, the liquid stored in the storage tank 4 is pumped into the interior of the adjusting swing arm 11 by the water pump 9, and the rice seedlings on both sides of the device are sprayed through the adjusting swing arm 11.

[0022] An installation cavity 14 is provided inside the ends of the two spray components 13 that are close to each other. Locking holes 15 are provided on the wall surfaces on both sides of the ends of the installation cavity 14 that are close to the spray components 13. The locking holes 15 are connected to the outer surface of the adjusting swing arm 11. A telescopic support rod 16 is movably installed between the two locking holes 15. The entire telescopic support rod 16 is a T-shaped structure and an adjusting knob is installed on the outside. When the adjusting swing arm 11 is rotated to lift, the lower end of the telescopic support rod 16 is pulled out and the knob on the outside of the telescopic support rod 16 is rotated.

The lifting angle of the adjusting swing arm 11 is maintained by the telescopic support rod 16, so that the spray range of the spray component 13 is improved and the coverage is wider.

[0023] The working principle of this utility model:

[0024] By providing an adjustable adjusting swing arm 11, after the two mounting bases 10 are installed separately from each other on the inner bottom surface of the mounting cross plate 6, the two adjusting swing arms 11 are respectively inserted into the openings at the top of the mounting base 10 and locked and installed by bolts, the telescopic support rod 16 is installed in the preset mounting cavity 14 inside the adjusting swing arm 11, and then the water delivery pipeline at the tail of the spray component 13 is connected with the shunt pipe on the output end of the water pump 9 through the connecting port 7. After the device is installed, when spraying the rice seedlings, the water pump 9 is started to push the push cart 1 to move, and the bottom of the two adjusting swing arms 11 extends out of the limit card slot 8 and touches the surface of the limit card slot 8. The water pump 9 drives the liquid in the storage tank 4 to be transported to the adjusting swing arm 11 through the delivery pipe and sprayed out through the spray hole at the bottom of the adjusting swing arm 11. When performing the spraying operation, the seedlings on both sides of the cart can be sprayed by only pushing the cart, which greatly reduces the amount of manual operation, reduces the fatigue of the user, and allows the operation to be performed for a long time.

[0025] By providing a telescopic support rod 16 for supporting and positioning, after the adjustment swing arm 11 is installed, the telescopic support rod 16 is installed between the two locking holes 15 opened inside the installation cavity 14, and the length of the telescopic support rod 16 is adjusted so that the telescopic support rod 16 is retracted into the inside of the installation cavity 14. After the two adjustment swing arms 11 are installed above the mounting cross plate 6, in the normal state, the two adjustment swing arms 11 are parallel to the surface of the pushing cart 1. When it is necessary to adjust the spray range to spray seedlings farther away, adjust the knob on the surface of the telescopic support rod 16 and pull up the telescopic support rod 16. The telescopic support rod 16 is pressed against the inner bottom surface of the mounting cross plate 6 to lift the entire adjustment swing arm 11, so that the spray range of the spray component 13 becomes wider. During the movement of the entire device, the expansion angle of the adjustment swing arm 11 can be adjusted to cover a large range of seedlings on both sides of the pushing cart 1, thereby improving the spraying efficiency.
