DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-6 A controlled-release urea spraying device includes a workbench 1, with rotating rollers 2 equidistantly connected to the upper part of the workbench 1 for rotation, a support frame 3 fixedly connected to the top of the workbench 1, a spray frame 4 slidably connected to the bottom of the support frame 3, a storage box 5 fixedly connected to the top of the support frame 3, a hose 6 is provided between the storage box 5 and the spray frame 4, one end of the hose 6 extends to the interior of the storage box 5 and a booster pump is installed, a push plate 20 is slidably connected to one side of the inner part of the workbench 1 through a limit rod, and a transmission assembly is provided on the outside of the workbench 1.

[0023] Specifically, the transmission assembly includes a reciprocating screw 7 and a linkage unit. The reciprocating screw 7 is rotatably connected to the bottom of the support frame 3, and the spray frame 4 is threadedly connected to the outside of the reciprocating screw 7. One side of the outside of the support frame 3 is fixedly connected to the first motor 8 through a limit plate. The output end of the first motor 8 extends to the inside of the support frame 3 and is fixedly connected to the reciprocating screw 7. The output end of the first motor 8 is fixedly connected to the first pulley 9. The rotating roller 2 can be rotated through the linkage unit. The linkage unit includes a worm gear 10, one end of which is connected to the outside of the workbench 1 through a rotating shaft and is fixedly connected to the worm gear 10. The outside of the workbench 1 is rotatably connected to a worm 11 through a limiting plate. The worm gear 10 and the worm gear 11 are meshed and connected. One end of the worm gear 11 is fixedly connected to a second pulley 12. The first pulley 9 and the second pulley 12 are connected by a first transmission belt 13. Every two adjacent rotating rollers 2 are fixedly connected to a third pulley 14 by a rotating shaft, and each group of third pulleys 14 are connected by an interlaced second transmission belt 15.

[0024] Through the above technical solution, firstly, the large-particle urea is evenly transported to the space between the multiple rotating rollers 2 through the external feeding equipment, and then the first motor 8 and the booster pump are started by the external controller. The output end of the first motor 8 can drive the reciprocating screw 7 to rotate, so that the reciprocating screw 7 drives the spray rack 4 to reciprocate under the limit of the support frame 3 through the threaded connection relationship. The surfactant inside the storage box 5 can be drawn into the inside of the spray rack 4 in conjunction with the booster pump, and then sprayed out through the nozzle 23. Under the reciprocating motion of the spray rack 4, the large-particle urea between the multiple groups of rotating rollers 2 is evenly sprayed, and the surfactant is evenly wrapped on the surface of the urea, which has a slow-release effect on the urea, so that the urea is slowly released when used, thereby extending the use time of urea and reducing the use of fertilizers. The surfactant covers the surface of urea to achieve slow release, which is an existing technology. When the first motor 8 is running, it can drive the first pulley 9 to rotate, so that the first pulley 9 drives the second pulley 12 and the worm 11 to rotate through the first transmission belt 13, and the worm 11 drives the worm wheel 10 and the first rotating roller 2 to rotate through the meshing relationship, so that the first rotating roller 2 drives the multiple groups of rotating rollers 2 to rotate continuously through the multiple groups of third pulleys 14 and the second transmission belt 15, and the large-particle urea on the top can be driven to roll continuously through the rotating roller 2, which can further improve the uniformity of spraying of the surfactant, avoid the trouble of the bottom of the stationary large-particle urea being difficult to be covered by the sprayed surfactant and requiring manual turning, thereby greatly improving the processing efficiency and reducing the labor burden.

[0025] Specifically, the side of the interior of the workbench 1 away from the limit rod is rotatably connected to the transmission screw 21, the push plate 20 is threadedly connected to the outside of the transmission screw 21, the outside of the workbench 1 is fixedly connected to the second motor 22 through the limit plate, the output end of the second motor 22 extends to the inside of the workbench 1 and is fixedly connected to the transmission screw 21, the side of the outside of the workbench 1 away from the push plate 20 is fixedly connected to the inclined plate 16, the top of the workbench 1 is fixedly connected to the side close to the inclined plate 16, the top of the fixed frame 17 is fixedly connected to the electric telescopic rod 18, the output end of the electric telescopic rod 18 passes through the fixed frame 17 and extends to the inside of the inclined plate 16 and is fixedly connected to a baffle 19.

[0026] Through the above technical solution, when the spraying of all the current large-particle urea is completed, the first motor 8 and the boost pump are turned off, and the second motor 22 and the electric telescopic rod 18 are started at the same time. The output end of the electric telescopic rod 18 drives the baffle 19 to rise, canceling the isolation of the large-particle urea, and the output end of the second motor 22 drives the transmission screw 21 to rotate, so that the transmission screw 21 drives the push plate 20 to move toward the inclined plate 16 under the limit of the limit rod through the threaded connection relationship, and the large-particle urea can be pushed toward the inclined plate 16 during the movement until all the large-particle urea is transported to the next processing step through the inclined plate 16, and the baffle 19 and the push plate 20 are driven to return to their positions through the reverse process operation.

[0027] Specifically, the bottom of the spray rack 4 is fixedly connected to the nozzle 23 at equal intervals, the top side of the storage box 5 is fixedly connected to the feed port 24, and the booster pump, the first motor 8, the electric telescopic rod 18 and the second motor 22 are all electrically connected to the external controller.

[0028] Through the above technical solution, when the surfactant inside the storage box 5 is insufficient, it can be added through the feed port 24, and the staff can quickly control the booster pump, the first motor 8, the electric telescopic rod 18 and the second motor 22 through the external controller.

[0029] During use, the large-particle urea is first evenly transported to the space between the multiple rotating rollers 2 through an external feeding device, and then the first motor 8 and the booster pump are started by an external controller. The output end of the first motor 8 can drive the reciprocating screw 7 to rotate, so that the reciprocating screw 7 drives the spray rack 4 to reciprocate under the limit of the support frame 3 through a threaded connection relationship. The surfactant inside the storage tank 5 can be drawn into the inside of the spray rack 4 in conjunction with the booster pump, and then sprayed out through the nozzle 23. Under the reciprocating motion of the spray rack 4, the large-particle urea between the multiple groups of rotating rollers 2 is evenly sprayed, and the surfactant is evenly wrapped in the urea. The surface of the surfactant has a slow-release effect on urea, so that the urea is slowly released when used, thereby extending the use time of urea and reducing the amount of fertilizer used. The slow release is achieved by covering the surface of urea with a surfactant, which is an existing technology. While the first motor 8 is running, it can drive the first pulley 9 to rotate, so that the first pulley 9 drives the second pulley 12 and the worm 11 to rotate through the first transmission belt 13, and the worm 11 then drives the worm wheel 10 and the first rotating roller 2 to rotate through the meshing relationship, so that the first rotating roller 2 drives the multiple groups of rotating rollers 2 to rotate continuously through multiple groups of third pulleys 14 and the second transmission belt 15. By rotating the roller 2, the large urea particles on the top can be driven to roll continuously, which can further improve the uniformity of the surfactant spraying and avoid the trouble of manual turning over of the bottom of the stationary large urea particles that are difficult to be covered by the sprayed surfactant, thereby greatly improving the processing efficiency and reducing the labor burden. When the spraying of all the large urea particles is completed, the first motor 8 and the booster pump are turned off, and the second motor 22 and the electric telescopic rod 18 are started at the same time. The output end of the electric telescopic rod 18 drives the baffle 19 to rise, canceling the isolation of the large urea particles, and the output end of the second motor 22 The transmission screw 21 is driven to rotate, so that the transmission screw 21 drives the push plate 20 to move toward the inclined plate 16 under the limit of the limit rod through the threaded connection relationship, and the large-particle urea is pushed toward the inclined plate 16 during the movement until all the large-particle urea is transported to the next processing step through the inclined plate 16. The baffle 19 and the push plate 20 are driven to return to their positions through the reverse process operation. When the surfactant inside the storage box 5 is insufficient, it can be added through the feed port 24. The external controller can facilitate the staff to quickly control the booster pump, the first motor 8, the electric telescopic rod 18 and the second motor 22.
