Description

Technical Field

[0001] The utility model belongs to the technical field of spraying fertilizers, in particular to an automatic proportioning device for spraying fertilizers. Background Art

[0002] In order to ensure the healthy growth of crops, it is necessary to spray fertilizers on them regularly. Fertilizers account for about 35% to 40% of the contribution to grain production. However, the nutrients in different soils are also different, so fertilizers cannot be used blindly. Instead, the staff must mix appropriate fertilizers according to the soil composition. In addition, the fertilizers required in different seasons are also different, so most fertilizers need to be mixed before they can be sprayed on crops.

[0003] However, most of the current fertilizer mixing work is done manually by staff. The staff need to take different amounts of fertilizers separately and then mix them. There is no effect when mixing a small amount of fertilizer, but once the amount of fertilizer increases, the mixing efficiency will be insufficient and it will cause a greater burden on the staff's body.

[0004] For this reason, we propose a fertilizer spraying automatic proportioning device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art and proposes an automatic proportioning device for fertilizer spraying.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] An automatic proportioning device for fertilizer spraying, comprising a proportioning box, the proportioning box comprising a mixing box and a motor box, a proportioning pipe fixedly connected to the top of the motor box, the mixing box fixedly arranged outside the proportioning pipe, the length of the proportioning pipe being greater than the height of the mixing box, an operating table installed on the outer wall of the motor box, a servo motor installed in the motor box, the operating table electrically connected to the servo motor, a telescopic rod fixedly connected to the output end of the servo motor, a threaded rod fixedly connected to the other end of the telescopic rod, a threaded hole provided on the top of the motor box, the threaded rod threadedly connected to the threaded hole, the threaded rod extending into the proportioning pipe, the threaded rod rotatably connected to a bottom plate at one end away from the servo motor, scale lines provided on the side wall of the proportioning pipe, the outer diameter of the bottom plate being consistent with the inner diameter of the proportioning pipe.

[0009] Preferably, two baffles are installed on the top wall of the mixing box. Both of the baffles are semicircular with a groove in the middle, and the inner wall of the groove abuts against the outer wall of the dispensing pipe.

[0010] Preferably, the discharge pipe is "L"-shaped, and a rubber tube is sleeved on the outside of one end of the discharge pipe away from the mixing box.

[0011] Preferably, two limiting rods are fixedly connected to the bottom wall of the baffle, two limiting grooves are respectively provided on both sides of the top wall of the mixing box, and the limiting rods are slidably connected to the inner walls of the limiting grooves.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] like Figure 1 - Figure 4 As shown, an automatic proportioning device for fertilizer spraying includes a proportioning box, which includes a mixing box 1 and a motor box 2. A proportioning pipe 3 is fixedly connected to the top of the motor box 2. The mixing box 1 is fixedly mounted outside the proportioning pipe 3. The mixing box 1 is in the shape of a truncated cone with a larger top and a smaller bottom. A discharge pipe 11 is connected to the bottom wall of the mixing box 1, and a valve 12 is installed on the side wall of the discharge pipe 11. The discharge pipe 11 is "L"-shaped and does not contact the motor box 2. A rubber tube 15 is sheathed on the outside of the discharge pipe 11 away from the mixing box 1. The rubber tube 15 is a flexible hose, which is more convenient for connecting to spraying equipment at different heights.

[0023] Two baffles 13 are installed on the top wall of the mixing box 1. Both baffles 13 are semicircular with a groove 14 in the middle. The inner wall of the groove 14 is against the outer wall of the dosing pipe 3. Two limit rods 16 are fixedly connected to the bottom wall of the baffle 13. Two limit grooves 17 are respectively provided on both sides of the top wall of the mixing box 1. The limit rods 16 are slidably connected to the inner walls of the limit grooves 17. When the fertilizer needs to be mixed, the baffle 13 can be removed. Normally, the baffle 13 can prevent dust from entering the mixing box 1.

[0024] The length of the dispensing pipe 3 is greater than the height of the mixing box 1. Therefore, when the base plate 9 rises, it pushes the fertilizer on the base plate 9 into the mixing box 1. An operating table 4 is mounted on the outer wall of the motor box 2. A servo motor 5 is mounted inside the motor box 2 and is electrically connected to the servo motor 5. The forward and reverse rotation of the servo motor 5 can be controlled by controlling the operating table 4. A telescopic rod 6 is fixedly connected to the output end of the servo motor 5. A threaded rod 7 is fixedly connected to the other end of the telescopic rod 6. A threaded hole 8 is defined in the top of the motor box 2, and the threaded rod 7 is threadedly connected to the threaded hole 8. The threaded rod 7 extends into the dispensing pipe 3 and is pivotally connected to the base plate 9 at the end away from the servo motor 5. Scale lines 10 are recessed on the side wall of the dispensing pipe 3. The depth of the scale lines 10 ranges from 1 mm to 1.5 mm. The shallowness of the scale lines 10 effectively prevents fertilizer particles from getting stuck inside the scale lines 10, thereby ensuring a clear reading. The outer diameter of the base plate 9 matches the inner diameter of the dispensing pipe 3.

[0025] The side wall of the dispensing pipe 3 is rotatably connected to a ring plate 18, and the top wall of the ring plate 18 is fixedly provided with a slope 19. The slope 19 can make the ejected fertilizer fall directly into the mixing box 1 without remaining on the ring plate 18. The side wall of the slope 19 is fixedly connected to a plurality of levers 20, and the bottom wall of the ring plate 18 is fixedly connected to a stirring rod 21. The stirring rod 21 can stir and mix the fertilizer in the mixing box 1.

[0026] The working principle is as follows: the staff first controls the operating table 4 to make the servo motor 5 rotate forward, and the telescopic rod 6 installed at the output end of the servo motor 5 will drive the threaded rod 7 to rotate together, and then the threaded rod 7 drives the bottom plate 9 to rise along the dispensing pipe 3. When the bottom plate 9 rises to the specified scale line 10, the servo motor 5 is stopped, and the staff pours the specified fertilizer into the dispensing pipe 3 until the fertilizer is flush with the top of the dispensing pipe 3, and starts the servo motor 5 again, so that the bottom plate 9 continues to push the fertilizer upward, and the fertilizer will fall into the mixing box 1, and then drive the servo motor 5 in the reverse direction to make the bottom plate 9 fall. When it falls to the new specified scale line 10, new fertilizer is poured in, and so on and so forth until all the fertilizers are automatically proportioned. Then, the annular plate 18 can be turned to drive the stirring rod 21 to stir and mix the fertilizer in the mixing box 1, and then the valve 12 is opened to allow the fertilizer to enter the spraying equipment through the discharge pipe 11 and the rubber tube 15.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
