Description

Technical Field

[0001] This utility model belongs to the technical field of ditching and fertilizing robots, specifically relating to an automatic ditching and fertilizing robot for orchards. Background Technology

[0002] Trench fertilization is a widely used technique in agricultural production, especially in orchards. This method involves digging trenches near the crop roots, applying fertilizer into the trenches, and then covering them with soil, thereby improving fertilizer utilization and crop growth quality. In daily life, to reduce workload and labor intensity, people often use robots for trench fertilization. However, most existing trench fertilization robots cannot achieve uniform fertilizer distribution, resulting in significant differences in the amount of fertilizer in different trenches.

[0003] A patent with publication number CN215301514U discloses a trenching and fertilizing machine, including a frame, a fertilizing component, and a trenching shovel. The fertilizing component includes a first fertilizer box and a second fertilizer box, both mounted on the frame. The first fertilizer box has a first discharge port, and the second fertilizer box has a second discharge port, which connects to the first and second fertilizer boxes. The frame is equipped with a trenching shovel, and a fertilizing pipe is fixedly connected to the trenching shovel. The fertilizing pipe is located below the first discharge port. A screw conveyor is provided inside the first and second fertilizer boxes. The screw conveyor is used to push the fertilizer in the first and second fertilizer boxes into the fertilizing pipe.

[0004] However, the above method cannot achieve timed fertilizer dispensing during the fertilization process, and cannot evenly distribute fertilizer in each trench, resulting in large differences in the amount of fertilizer in different trenches. This leads to uneven growth quality of fruit trees in the orchard, which not only affects the overall aesthetics of the orchard, but also has a certain impact on the yield of fruit trees. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides an automatic ditching and fertilizing robot for orchards.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic ditching and fertilizing robot for orchards includes a robot body. A box is fixedly installed on one side of the robot body. A sliding plate is mounted vertically inside the box. A ditching plow is fixedly installed at the bottom of the sliding plate. A material feeding channel is opened through the ditching plow and passes through the sliding plate. A through hole is opened at the top of the box. A material feeding pipe is opened on the inner wall of the top of the box and communicates with the through hole. The material feeding pipe and the material feeding channel are slidably engaged and communicate with each other. Two rotating plates are rotatably installed facing each other inside the through hole. The two rotating plates rotate to block the through hole. A first hinge seat is fixedly installed at the top of each rotating plate. A storage box is fixedly installed at the top of the box. The bottom of the storage box communicates with the through hole. A connecting sleeve is slidably installed vertically inside the storage box. A driving mechanism acting on the connecting sleeve is provided on the storage box. Two second hinge seats are symmetrically arranged on the outer surface of the connecting sleeve. The second hinge seats correspond one-to-one with the first hinge seats. Each second hinge seat is connected to the corresponding first hinge seat by a hinge rod.

[0008] Furthermore, a fixed cylinder is fixedly installed at the bottom of the slide plate, and a slide rod is slidably installed in the fixed cylinder along the vertical direction. A flat plate is fixedly installed at the bottom of the slide rod. A spring is provided between the slide rod and the fixed cylinder, and the extension and contraction direction of the spring is the same as the sliding direction of the slide rod.

[0009] Furthermore, the drive mechanism includes a motor, with the motor fixedly mounted on the top of the storage box. The output shaft of the motor extends rotatably into the storage box and a rotating shaft is fixedly installed therein. The rotating shaft is slidably engaged with the connecting sleeve, and a reciprocating screw is fixedly installed at the bottom of the rotating shaft. The reciprocating screw is threadedly engaged with the connecting sleeve, and the reciprocating screw is always located inside the connecting sleeve. The reciprocating screw, the connecting sleeve, and the balls form a ball screw pair.

[0010] Furthermore, a plurality of stirring rods are fixedly arranged on the outer surface of the rotating shaft, and the plurality of stirring rods are arranged in a circular array along the central axis of the rotating shaft; a feed pipe is fixedly arranged on the top of the storage tank.

[0011] Furthermore, an electric push rod is fixedly installed on the top of the box, and the telescopic shaft of the electric push rod is fixedly connected to the top of the slide plate.

[0012] This application has the following beneficial effects:

[0013] 1. During the process of digging ditches in the land, the drive mechanism can control the connecting sleeve to slide up and down, causing the rotating plate to rotate back and forth, thereby achieving an intermittent sealing effect on the through hole, enabling intermittent fertilizer application, so that the amount of fertilizer applied each time is roughly the same, thus ensuring that the amount of fertilizer in different ditches is roughly the same, achieving uniform fertilizer application.

[0014] 2. The start-up drive mechanism can also drive the stirring rod to rotate through the rotating shaft, thereby agitating the clumps of fertilizer and avoiding blockage of the discharge pipe and uneven distribution caused by fertilizer clumps, resulting in better overall practical effect.

[0015] 3. The spring mechanism allows the flat plate to be better suited for ground of different heights, thus achieving a more ideal leveling effect. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: an automatic ditching and fertilizing robot for orchards, including a robot body 1, a control unit (not shown in the figure) is provided inside the robot body 1, the control unit is used to control the movement of the robot body 1, the control unit is prior art, and this solution will not be described in detail.

[0026] A box 4 is fixedly installed on one side of the robot body 1. An electric push rod 5 is fixedly installed on the top of the box 4. The telescopic shaft of the electric push rod 5 slides through the top of the box 4 and a slide plate 6 is fixedly installed thereon. The slide plate 6 is limited and slidably installed inside the box 4 in the vertical direction.

[0027] A trenching plow 10 and a fixing cylinder 7 are fixedly installed at the bottom of the sliding plate 6. A material discharge channel 11 is formed on the trenching plow 10, penetrating both itself and the sliding plate 6. A sliding rod 25 is vertically slidable inside the fixing cylinder 7, and a leveling plate 8 is fixedly installed at the bottom of the sliding rod 25. The leveling plate 8 is used to level the area after trenching and fertilization. A spring 26 is provided between the sliding rod 25 and the fixing cylinder 7. The extension and retraction direction of the spring 26 is the same as the sliding direction of the sliding rod 25. The top of the spring 26 is fixedly connected to the fixing cylinder 7, and the bottom of the spring 26 is fixedly connected to the sliding rod 25. The spring 26 allows the leveling plate 8 to be better suited to different ground heights, facilitating a more ideal leveling effect.

[0028] A through hole 12 is provided on the top of the box body 4, and a material discharge pipe 9 communicating with the through hole 12 is fixedly provided on the inner wall of the bottom of the box body 4. The material discharge pipe 9 is slidably engaged with the material discharge channel 11 and the two are connected.

[0029] Two rotating plates 14 are rotatably arranged in opposite directions inside the through hole 12. A connecting shaft 13 is provided at the rotatable connection of the two rotating plates 14. The two rotating plates 14 rotatably block the through hole 12. A first hinge seat 15 is fixedly provided on the top of the two rotating plates 14.

[0030] A storage box 16 communicating with the through hole 12 is fixedly installed on the top of the box body 4. A connecting sleeve 22 is slidably installed in the vertical direction inside the storage box 16. Two second hinge seats 23 are symmetrically fixed on the outer surface of the connecting sleeve 22. The second hinge seats 23 correspond one-to-one with the first hinge seats 15. Each second hinge seat 23 is provided with a hinge rod 24 between it and the corresponding first hinge seat 15. Both ends of the hinge rod 24 are hinged to the first hinge seat 15 or the second hinge seat 23 connected to it.

[0031] The storage bin 16 is equipped with a drive mechanism that acts on the connecting sleeve 22. The drive mechanism includes a motor 17, which is fixedly mounted on the top of the storage bin 16. The output shaft of the motor 17 extends rotatably into the storage bin 16 and is fixedly mounted with a rotating shaft 19. The rotating shaft 19 is slidably engaged with the connecting sleeve 22. A reciprocating screw 21 is coaxially fixedly mounted at the bottom of the rotating shaft 19. The reciprocating screw 21 is threadedly engaged with the connecting sleeve 22, and the reciprocating screw 21 is always located inside the connecting sleeve 22. The reciprocating screw 21, the connecting sleeve 22, and the balls form a ball screw pair.

[0032] In addition, several stirring rods 20 are fixedly installed on the outer surface of the rotating shaft 19, and the stirring rods 20 are arranged in a circular array along the central axis of the rotating shaft 19. A feed pipe 18 is fixedly installed on the top of the storage tank 16.

[0033] Working principle: During use, fertilizer is fed into the storage bin 16 through the feed pipe 18. Activating the electric push rod 5 causes the sliding plate 6 to slide downwards via its telescopic shaft, bringing the ditching plow 10 and the leveling plate 8 into contact with the ground. During this process, the discharge pipe 9 and the discharge channel 11 slide relative to each other.

[0034] As the skateboard 6 gradually slides down, the ditching plow 10 inserts into the ground, while the slide bar 25 slides in the direction of the compression of the spring 26, so that the flat plate 8 always keeps in contact with the ground, thus making it suitable for ground of different heights.

[0035] The robot body 1 is driven to move by the control unit. During the movement of the robot body 1, the ditching plow 10 will dig trenches in the ground. The motor 17 is started, and the output shaft of the motor 17 drives the connecting shaft 13 to rotate. The rotation of the connecting shaft 13 will drive several stirring rods 20 to rotate, thereby stirring the inside of the storage box 16 and preventing the fertilizer from getting damp and clumping, which would cause blockage of the discharge pipe 9.

[0036] Meanwhile, the rotation of the rotating shaft 19 also drives the reciprocating screw 21 to rotate, causing the connecting sleeve 22 to slide up and down reciprocally. This, in turn, pulls the two rotating plates 14 around the central axis of the connecting shaft 13 via the hinge rod 24, causing the two rotating plates 14 to reciprocate during the opening and closing process. When the rotating plates 14 are open, fertilizer falls onto the ground sequentially through the discharge pipe 9 and the discharge channel 11. When the rotating plates 14 are closed, they impede the fall of fertilizer, thus achieving an intermittent sealing effect on the through hole 12. This allows for intermittent fertilizer dispensing, ensuring that the amount of fertilizer dispensed each time is approximately the same, thereby guaranteeing that the amount of fertilizer in different ditches is roughly the same and achieving uniform feeding.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
