Description

Technical Field

[0001] The utility model generally relates to the field of agricultural machinery, and in particular to a drone fertilizer adding device. Background Art

[0002] Fertilization is the agricultural practice of applying fertilizer to the soil to provide nutrients needed by plants and maintain and improve soil fertility. The primary purpose of fertilization is to increase crop yields and improve crop quality. Currently, drones are commonly used for large-scale fertilization to improve fertilization efficiency. However, due to the limited carrying capacity of drones, multiple fertilization attempts are required to complete the fertilization task.

[0003] In the prior art, fertilizer is generally added to drones manually, which increases the labor intensity of the workers and has low fertilizer efficiency. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a drone fertilizer adding device that reduces the labor intensity of workers.

[0005] In the first aspect, the drone fertilizer adding device of the utility model comprises:

[0006] A large silo is provided with a first accommodating chamber for storing fertilizer, a first material inlet is provided at the top of the first accommodating chamber, a first material outlet is provided at the first accommodating chamber, and an auger conveying mechanism is provided at the first material outlet to transfer the fertilizer in the first accommodating chamber to the first material outlet;

[0007] A small hopper is provided with a second accommodating chamber for temporarily storing fertilizer, a second inlet is provided at the top of the second accommodating chamber, a second outlet is provided at the bottom of the second accommodating chamber, and the second outlet is rotatably connected to a flip plate, which is used to open and close the second outlet;

[0008] The telescopic mechanism is provided with a fixed end and a movable end, wherein the fixed end is connected to the outer side wall of the large hopper, and the small hopper is connected to the movable end.

[0009] According to the technical solution provided in the embodiment of the present application, when it is necessary to add fertilizer to the drone, the drone stops at the fertilizer adding area, the small hopper is located below the first discharge port, and the auger conveying mechanism transfers the fertilizer in the first accommodating chamber to the first discharge port. The fertilizer falls from the first discharge port and enters the second accommodating chamber through the second feed port. The second accommodating chamber temporarily stores the fertilizer. After the fertilizer for a single fertilization completely enters the second accommodating chamber, the auger conveying mechanism stops moving, and the telescopic mechanism begins to extend, transferring the small hopper to directly above the drone. After the small hopper moves to directly above the drone, the telescopic mechanism stops moving, the flip plate begins to flip and open the second discharge port, and the fertilizer falls from the second discharge port and enters the drone to add fertilizer to the drone. After the fertilization is completed, the flip plate flips and closes the second discharge port, and the telescopic mechanism contracts and resets, thereby achieving the addition of fertilizer to the drone, reducing the labor intensity of the staff and improving the efficiency of fertilization.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0015] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] Please refer to Figures 1 to 3The drone fertilizer adding device of the present invention includes: a large hopper 100, which is provided with a first accommodating chamber 110 for storing fertilizer, a first feeding port 111 is provided at the top of the first accommodating chamber 110, a first discharging port 112 is provided at the first accommodating chamber 110, and an auger conveying mechanism 120 is provided at the first discharging port 112, and the auger conveying mechanism 120 transfers the fertilizer in the first accommodating chamber 110 to the first discharging port 112; a small hopper 200, which is provided with a second accommodating chamber 210 for temporarily storing fertilizer, a second feeding port 211 is provided at the top of the second accommodating chamber 210, a second discharging port 212 is provided at the bottom of the second accommodating chamber 210, and the second discharging port 212 is rotatably connected to a flip plate 220, and the flip plate 220 is used to open and close the second discharging port 212; a telescopic mechanism 300, which is provided with a fixed end and a movable end, the fixed end is connected to the outer wall of the large hopper 100, and the small hopper 200 is connected to the movable end.

[0017] In an embodiment of the present invention, the large silo 100 is used to store fertilizer. A tire 160 can be provided at the bottom of the large silo 100, and the large silo 100 can be moved by being dragged by a tractor, thereby improving the mobility of the drone fertilizer adding device. When using a drone for fertilizing, the large silo 100 can store enough fertilizer in the first accommodating chamber 110, reducing the number of times fertilizer is taken out from the warehouse. A first feed port 111 is provided at the top of the first accommodating chamber 110. When the large silo 100 is replenished with fertilizer, the fertilizer in the warehouse enters the large silo 100 from the first feed port 111. The first accommodating chamber 110 is provided with a first discharge port 112, and the first discharge port 112 is provided with a auger transmission mechanism. The auger transmission mechanism is located at the bottom of the first accommodating chamber 110. The auger transmission mechanism transmits the fertilizer in the first accommodating chamber 110 to the first discharge port 112. The auger transmission mechanism has the advantages of simple structure, low manufacturing cost, and easy maintenance, and the auger transmission mechanism has high transmission accuracy.

[0018] The fixed end of the telescopic mechanism 300 is connected to the large silo 100, and the small hopper 200 is connected to the mobile end. When the telescopic mechanism 300 is extended or retracted, the mobile end will move relative to the fixed end, that is, it will drive the small hopper 200 to move relative to the large silo 100. Specifically, when the telescopic mechanism 300 is extended, the small hopper 200 moves away from the large silo 100 and is extended; when the telescopic mechanism 300 is contracted, the small hopper 200 approaches the large silo 100 and is retracted. When the telescopic mechanism 300 is in the retracted state, the second inlet 211 of the small hopper 200 is located below the first outlet 112. When the auger conveying mechanism 120 transfers fertilizer from the first accommodating chamber 110 to the first outlet 112, the fertilizer falls from the first outlet 112 and enters the second accommodating chamber 210 through the second inlet 211, replenishing the small hopper 200. The small hopper 200 is used to temporarily store fertilizer. When the telescopic mechanism 300 is in the extended and retracted state, the small hopper 200 is driven above the drone, and the second outlet 212 is located above the drone's feed box inlet.

[0019] When fertilizer needs to be added to the drone, the drone stops at the fertilizer application area, the small hopper 200 is located below the first discharge port 112, and the auger conveying mechanism 120 transfers the fertilizer in the first accommodating chamber 110 to the first discharge port 112. The fertilizer falls from the first discharge port 112 and enters the second accommodating chamber 210 through the second feed port 211. The second accommodating chamber 210 temporarily stores the fertilizer. After the fertilizer for a single application has completely entered the second accommodating chamber 210, the auger conveying mechanism 120 stops, and the telescopic mechanism 300 begins to extend, transferring the small hopper 200 to directly above the drone. After the small hopper 200 moves to directly above the drone, the telescopic mechanism 300 stops, and the flip plate 220 begins to flip and open the second discharge port 212. The fertilizer falls from the second discharge port 212 and enters the drone, thus adding fertilizer to the drone. After the fertilizer is added, the flip plate 220 flips over and closes the second discharge port 212, and the telescopic mechanism 300 shrinks and resets, thereby adding fertilizer to the drone, reducing the labor intensity of the staff and improving the fertilizer addition efficiency.

[0020] Furthermore, the telescopic mechanism 300 includes a scissor-type telescopic arm 310 and a driving mechanism, and the driving mechanism drives the scissor-type telescopic arm 310 to extend and retract.

[0021] In this embodiment of the present invention, a drive mechanism drives the telescopic scissor-like arm 310 to extend and retract, thereby driving the movement of the small hopper 200. The telescopic scissor-like arm 310 offers advantages such as a simple telescopic structure, low manufacturing cost, and excellent stability. When the drone fertilizer dispenser is not in use, the telescopic scissor-like arm 310 can be retracted, reducing the volume occupied by the drone fertilizer dispenser.

[0022] Furthermore, the driving mechanism includes a first motor and a screw, the screw is rotatably connected to the large silo 100, the first motor drives the screw to rotate, and the scissor-type telescopic arm 310 is fixedly connected with a nut, which is threadedly connected to the screw.

[0023] In the embodiment of the present invention, a screw and nut form a screw-nut mechanism. A first motor drives the screw to rotate, thereby driving the nut to translate, and in turn, the scissor-type telescopic arm 310 to telescope. This screw-nut mechanism has a large load capacity and is self-locking, improving the stability and reliability of the drone fertilizer feeding device. Furthermore, the screw-nut mechanism offers high transmission accuracy, enabling precise control of the scissor-type telescopic arm 310.

[0024] Furthermore, a cover plate 130 is flipped and connected to the top of the large silo 100 , and the cover plate 130 is used to open and close the first feed port 111 .

[0025] In an embodiment of the present invention, when using the drone fertilizer adding device, the cover 130 can be used to cover the first feed port 111 to prevent debris from entering the first accommodating chamber 110 through the first feed port 111 and disturbing the fertilizer. This also prevents strong winds from blowing the fertilizer out of the first accommodating chamber 110, thereby improving the environmental adaptability of the drone fertilizer adding device. When adding fertilizer to the large silo 100, the cover 130 can be opened to prevent it from affecting fertilizer replenishment.

[0026] Furthermore, a standing platform 140 and a ladder 150 are fixedly connected to the outer side wall of the large silo 100 , and a handrail pipe is fixedly connected to the outer edge of the standing platform 140 .

[0027] In the embodiment of the present invention, the staff enters and exits the standing platform 140 via the ladder 150. The staff can stand on the standing platform 140 to rotate the cover 130 to open or close the first feeding port 111. The staff can stand on the standing platform 140 to observe the condition of the fertilizer in the first accommodating chamber 110.

[0028] Furthermore, the auger conveying mechanism 120 includes a transmission shaft 121 and a second motor. The transmission shaft 121 is fixedly connected to a spiral blade 122 , and the second motor drives the transmission shaft 121 to rotate.

[0029] In an embodiment of the present utility model, the second motor drives the transmission shaft 121 to rotate, and the transmission shaft 121 drives the spiral blade 122 to rotate, thereby realizing the transmission of the fertilizer in the first accommodating chamber 110 to the first discharge port 112. The auger transmission mechanism has the advantages of simple structure, low manufacturing cost, easy maintenance, etc., and the auger transmission mechanism has high transmission accuracy.

[0030] Furthermore, a third motor is included. The first discharge port 112 is rotatably connected to a warehouse door 113 . The warehouse door 113 is used to open and close the first discharge port 112 . The third motor drives the warehouse door 113 to rotate.

[0031] In an embodiment of the present invention, when delivering fertilizer to the small hopper 200, the third motor drives the door 113 to rotate, opening the first discharge port 112, allowing fertilizer to enter the second accommodating chamber 210 through the first discharge port 112. When the drone is not needed to add fertilizer, the door 113 closes the first discharge port 112 to prevent fertilizer from flowing out of the first discharge port 112. The third motor and the door 113 may be driven by, but are not limited to, gears.

[0032] Furthermore, the small hopper 200 is fixedly connected to a fourth motor, the flip plate 220 is fixedly connected to a rotating shaft 230, the rotating shaft 230 is rotationally connected to the small hopper 200, and the fourth motor drives the rotating shaft 230 to rotate.

[0033] In the embodiment of the present invention, the fourth motor is used to drive the flip plate 220 to rotate, thereby realizing the opening and closing of the second discharge port 212, further reducing the labor intensity of the staff.

[0034] Furthermore, the second discharge port 212 is bound with a passing bag 213 .

[0035] In an embodiment of the present invention, when fertilizing the drone, the fertilizer in the second accommodating chamber 210 passes through the second discharge port 212 and then passes through the bag 213 to enter the drone. The bag 213 can buffer the fertilizer and reduce the impact of the fertilizer on the drone.
