Description

Technical Field

[0001] The present invention relates to the technical field of fertilizing devices, and in particular to a wheat fertilizing device using a drone. Background Art

[0002] In today's agricultural modernization process, wheat, as an important food crop, is of vital importance for its efficient and sustainable cultivation. Traditional wheat fertilization mostly relies on manual labor or large-scale ground agricultural machinery to spread fertilizer. Manual fertilization is extremely inefficient. The area that a worker can fertilize in a day is very limited. It is also extremely labor-intensive and labor-intensive, with high labor costs. It is also difficult to ensure the uniformity of fertilization, which can easily result in too much or too little fertilizer in some areas, affecting the consistency of wheat growth and the final yield. Although large-scale ground agricultural machinery is more efficient than manual labor, it has high requirements for the flatness of farmland and is difficult to use in complex terrain, small fields or terraced areas. In addition, agricultural machinery entering the field will compact the soil, destroy the soil structure, affect the growth of wheat roots and the air permeability and water retention of the soil, and increase the cost of subsequent soil improvement. Therefore, it is necessary to use drone fertilization devices. An existing drone fertilization mechanism (Announcement No.: CN218680031U) has the following shortcomings during use: When spreading dry fertilizer on wheat, the fertilizer enters the fertilizer pipe from the discharge pipe. Since the fertilizer pipe is fixed below the discharge pipe, the fertilizer is not easy to flow in the fertilizer pipe and then be discharged through the fertilizer nozzle, causing the fertilizer to easily get blocked in the fertilizer pipe, thereby affecting the fertilization efficiency. For this reason, this patent proposes a wheat drone fertilizing device to solve the above problem. Summary of the Invention

[0003] The purpose of the present invention is to provide a wheat drone fertilizing device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a wheat drone fertilizing device, comprising a drone and a drone bracket, a storage box is provided on the top of the drone bracket, a mounting plate is fixed on the top of the storage box, the bottom end of the mounting plate is rotatably connected to a rotating rod, a motor is fixed on the top of the mounting plate, the output end of the motor passes through the mounting plate and is fixed to the rotating rod, an auger is fixed on the outer wall of the rotating rod, a discharge port is provided at the bottom end of the storage box, a discharge pipe is fixedly connected to the bottom end of the storage box, the auger is in contact with the inner wall of the discharge pipe, a feed pipe is rotatably connected to the outer wall of the discharge pipe, a plurality of fertilizer nozzles are fixedly connected to the feed pipe, the rotating rod is fixed to the outer wall of the rotating rod, a scraper is fixed to the bottom end of the mounting rod, and the scraper is in contact with the inner wall of the storage box and the inner wall of the discharge port.

[0005] Preferably, the bottom end of the discharge pipe is tilted downward to facilitate the discharge of fertilizer.

[0006] Preferably, a bearing is fixed to the outer wall of the discharge pipe, and the outer wall of the bottom end of the bearing is fixed to the discharge pipe.

[0008] Preferably, a fixing frame is fixed to the outer wall of the storage box, and the fixing frame is fixed to the drone bracket.

[0009] Preferably, a fixed leg is fixed to the bottom end of the drone bracket, and a roller is provided on the fixed leg.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By starting the motor, the motor drives the rotating rod to rotate, and the rotation of the rotating rod drives the auger to rotate. The rotation of the auger drives the material in the storage box to move downward, enter the discharge pipe through the discharge port and the discharge pipe, and is discharged through the fertilizer nozzle to fertilize the wheat. The rotation of the rotating rod drives the discharge pipe and the mounting rod to rotate. The rotation of the discharge pipe significantly improves the fluidity of the fertilizer through centrifugal force, so that the fertilizer can flow better in the discharge pipe to avoid blockage. At the same time, the fertilizer can be sown in different positions. The rotation of the mounting rod drives the scraper to rotate to clean the inner wall of the storage box and the inner wall of the discharge port to avoid fertilizer adhering to the storage box and causing waste.

[0013] 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.

[0014] In today's agricultural modernization, wheat, as an important food crop, is crucial for its efficient and sustainable cultivation. Traditional wheat fertilization relies on manual labor or large-scale ground-based agricultural machinery. Manual fertilization is extremely inefficient, with a worker's daily fertilization area being very limited. It is also labor-intensive and labor-intensive, with high labor costs. It also struggles to ensure uniform fertilization, which can easily result in areas receiving too much or too little fertilizer, impacting wheat growth consistency and ultimate yield. While large-scale ground-based agricultural machinery is more efficient than manual labor, it requires high field flatness, making it difficult to operate in complex terrain, small plots, or terraced areas. Furthermore, agricultural machinery operations in the fields compact the soil, disrupting its structure, affecting wheat root growth, soil permeability, and water retention, increasing subsequent soil improvement costs. This is why drone-based fertilization devices are becoming increasingly popular.

[0015] like Figure 1-Figure 4 As shown, the present invention provides a technical solution: a wheat drone fertilizing device, comprising a drone and a drone bracket 1, a storage box 2 is penetrated at the top of the drone bracket 1, a mounting plate 5 is fixed at the top of the storage box 2, a rotating rod 6 is rotatably connected to the bottom end of the mounting plate 5, a motor 14 is fixed to the top of the mounting plate 5, the output end of the motor 14 passes through the mounting plate 5 and is fixed to the rotating rod 6, a screw dragon 7 is fixed to the outer wall of the rotating rod 6, a discharge port 4 is opened at the bottom end of the storage box 2, a discharge pipe 8 is fixedly connected to the bottom end of the storage box 2, the screw dragon 7 contacts the inner wall of the discharge pipe 8, the outer wall of the discharge pipe 8 is rotatably connected to the discharge pipe 12, the bottom end of the discharge pipe 12 is fixedly connected to a plurality of fertilizer nozzles 13, the rotating rod 6 is fixed to the discharge pipe 12, a mounting rod 9 is fixed to the outer wall of the rotating rod 6, a scraper 10 is fixed to the bottom end of the mounting rod 9, and the scraper 10 contacts the inner wall of the storage box 2 and the inner wall of the discharge port 4. The bottom of the feed pipe 12 is tilted downwards to facilitate the feeding of fertilizer. The outer wall of the discharge pipe 8 is fixed with a bearing 11, and the outer wall of the bottom end of the bearing 11 is fixed to the feed pipe 12.

[0016] It should be noted that by starting the motor 14, the motor 14 drives the rotating rod 6 to rotate, and the rotation of the rotating rod 6 drives the auger 7 to rotate. The rotation of the auger 7 drives the material in the storage box 2 to move downward, enter the discharge pipe 12 through the discharge port 4 and the discharge pipe 8, and is discharged through the fertilizer nozzle 13 to fertilize the wheat. The rotation of the rotating rod 6 drives the discharge pipe 12 and the mounting rod 9 to rotate. The rotation of the discharge pipe 12 allows the fertilizer to flow better in the discharge pipe 12 to avoid blockage, and at the same time, the fertilizer can be sown at different positions. The rotation of the mounting rod 9 drives the scraper 10 to rotate, and the inner wall of the storage box 2 and the inner wall of the discharge port 4 are cleaned to avoid fertilizer adhering to the storage box 2 and causing waste.

[0017] like Figure 1As shown, a mounting shell 15 is fixed to the outer wall of the storage box 2, and a cover plate 16 is installed on the top of the mounting shell 15.
