Description

Technical Field

[0001] This invention belongs to the field of tea garden fertilization technology, specifically a pure electric ride-on tracked fertilizer for tea gardens. Background Technology

[0002] Traditional manual fertilization methods have been gradually replaced by machinery. Currently, tea garden fertilization is mainly carried out by tracked fertilizer applicators, which are powered by electricity. Compared with traditional fuel-powered models, they have the advantages of zero emissions, low noise, and low operating costs.

[0003] The prior art document, CN115176573B, discloses a side-position deep fertilization machine for tea gardens in hilly and mountainous areas. It includes a frame, drive system, rotary ditching device system, double-disc ditching system, synchronous fertilization system, transmission system, compaction system, and ditching depth control system. An engine drives the tracks via a power chassis, simultaneously driving the rotary ditching device to break up and dump soil. The ditching depth control system controls an electromagnetic reversing valve to change the pressure and flow rate of the gas delivered by the air pump. The gas is transmitted to cylinders on a parallel four-bar linkage, which adjust the ditching depth of the double-disc ditching device. Simultaneously, a battery supplies power to the drive device, ensuring that the grooved wheel of the synchronous fertilization device is proportional to the overall machine speed, guaranteeing uniform fertilization. Finally, the compaction system compacts the soil and fertilizer, completing the fertilization process. This design not only enables high-precision and efficient fertilization in hilly and mountainous areas but also features a lightweight and flexible mechanical design. Although the above-mentioned device uses an engine to drive the machinery forward during the fertilization process, and the rotating trenching device, the double-disc trenching system, the synchronous fertilization system, and the compaction system operate in sync, completing the steps of trenching, deep fertilization, and soil covering during the forward movement, thus improving the efficiency of fertilization, the fertilizer feeding process has not been optimized. The caking of fertilizer may result in uneven feeding. Summary of the Invention

[0004] The purpose of this invention is to provide a pure electric ride-on tracked fertilizer applicator for tea gardens that can fully disperse fertilizer and distribute it evenly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pure electric ride-on tracked fertilizer applicator for tea gardens, comprising a frame, a cab fixedly connected to the top of the frame, a track assembly fixedly connected to the bottom of the frame, a trenching assembly fixedly connected to the end of the track assembly, a battery pack fixedly connected to one side of the middle of the frame, and a fertilizer hopper fixedly connected to the other side of the middle of the frame, and further comprising: A reverse auger mechanism, located on the upper side of the fertilizer hopper; A chain conveyor mechanism, located below the fertilizer hopper; The reverse auger mechanism includes a pair of rotating rods rotatably connected to both sides of the fertilizer hopper. A spiral blade is fixed to one side of each rotating rod, and a lever is fixed to the other side. Both sides of the fertilizer hopper have discharge ports. The reverse auger mechanism above the fertilizer hopper, through the cooperation of the rotating rods and spiral blades, effectively pushes fertilizer from the hopper to the discharge ports, ensuring continuous fertilizer flow. The chain conveyor mechanism below is responsible for transporting fertilizer from the discharge ports to the fertilization position, achieving precise fertilization. The cooperation of these components not only improves fertilization efficiency but also ensures a smooth and reliable fertilization process.

[0006] Preferably, the reverse auger mechanism further includes protective shells fixed to both sides of the fertilizer hopper. A dual-head motor is fixedly connected to the inner cavity of each protective shell. A first gear is fixedly connected to the first output end of the dual-head motor, and there are two first gears. The two first gears mesh with a first chain. The side wall of the first gear is fixedly connected to the end of the rotating rod. Large pieces of compacted fertilizer are pushed in the opposite direction by the spiral blades and moved to the position of the lever. As the lever rotates continuously, it breaks up the compacted fertilizer. After this series of actions, all the fertilizer can finally enter the discharge port smoothly, preparing for subsequent fertilization.

[0007] Preferably, an eccentric wheel is fixedly connected to the end of the rotating rod near the lever, and a connecting rod is rotatably connected to the side wall of the eccentric wheel.

[0008] Preferably, the end of the connecting rod away from the eccentric wheel is rotatably connected to a sliding plate, and the sliding plate is slidably connected to the side wall of the fertilizer hopper via a slide rail.

[0009] Preferably, brackets are fixed to both sides of the slide rail, the brackets are U-shaped and snapped into the side wall of the fertilizer hopper.

[0010] Preferably, a conical panel is fixedly connected to the inner side of the bracket, and an arc-shaped pressure plate is fixedly connected to the bottom of the conical panel. Both the conical panel and the arc-shaped pressure plate slide against the inner wall of the fertilizer hopper. When the rotating rod rotates, it can also drive the rotation of the eccentric wheel synchronously. The movement of the eccentric wheel causes the end of the connecting rod to move back and forth continuously, thereby making the slide plate slide back and forth on the slide rail. The movement of the slide plate further drives the bracket to move up and down back and forth. The conical panel connected to the inner side also moves back and forth at the corner of the fertilizer hopper. The advantage of this design is that the arc-shaped pressure plate at the bottom can move up and down accordingly, effectively twisting and crushing the clumped fertilizer in the lever area, thereby enhancing the dispersing effect.

[0011] Preferably, the chain conveyor mechanism includes a support frame fixed to the bottom of the fertilizer hopper, and a second gear is fixed to the second output end of the dual-head motor, and there are two second gears.

[0012] Preferably, the two second gears mesh together with a second chain, and a transmission component is fixedly connected to the side wall of the second gear, the transmission component being mounted on a support frame.

[0013] Preferably, a plurality of U-shaped plates are fixedly connected at equal intervals on the surface of the conveying component, and an arc-shaped plate is fixedly connected to the middle of each U-shaped plate.

[0014] Preferably, a discharge baffle is rotatably connected to the bottom of the fertilizer hopper. Grooves are provided on both sides of the arc-shaped plate, and the depth is adapted to the edge of the discharge baffle. A torsion spring is sleeved on the outer wall of the fertilizer hopper through a small shaft, and the end of the torsion spring abuts against the side wall of the discharge baffle. Through multiple arc-shaped plates that are evenly distributed, the fertilizer is evenly separated to ensure that the amount of fertilizer applied is consistent. When the fertilizer reaches the position of the discharge baffle, the discharge baffle uses a scraping function to smooth the surface of the fertilizer separated by the arc-shaped plates, ensuring that the volume of fertilizer in the interval area is relatively consistent and avoiding the occurrence of accumulation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention facilitates the crushing and dispersing of compacted fertilizer through the combination of a lever, an arc-shaped pressure plate, and spiral blades. During fertilizer feeding, the spiral blades and lever rotate synchronously. Loose fertilizer enters the feeding port through the gaps in the spiral blades, while large pieces of compacted fertilizer are pushed to the lever by the reverse motion of the spiral blades. The lever's continuous rotation breaks them up, and they all enter the feeding port together. Furthermore, the linkage between the eccentric wheel and the support causes the arc-shaped pressure plate at the bottom to press down repeatedly, further crushing the compacted fertilizer in the lever area and enhancing the dispersing effect. This ensures the fertilizer is loose and continuously fed downwards, effectively preventing large-area compaction and accumulation. It not only improves the lever's ability to fully disperse lumpy waste but also avoids fertilizer scattering and waste.

[0016] This invention facilitates uniform discharge and prevents blockages by using a combination of discharge baffles and arc-shaped plates. Fertilizer falls onto the surface of the conveyor and is evenly separated by multiple equally spaced arc-shaped plates. When the fertilizer reaches the discharge baffle, the grooves on both sides of the arc-shaped plates, with depths matching the edges of the discharge baffle, smooth the surface of the fertilizer separated by the arc-shaped plates, ensuring a relatively uniform volume of waste in the interval area and preventing accumulation. Furthermore, when encountering large foreign objects, the discharge baffle is automatically pushed open and discharged, and a torsion spring resets the discharge baffle, applying pre-tension.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 12As shown, the present invention provides a pure electric ride-on tracked fertilizer applicator for tea gardens, including a frame 100, a cab 800 fixedly connected to the top of the frame 100, a track assembly 300 fixedly connected to the bottom of the frame 100, a trenching assembly 400 fixedly connected to the end of the track assembly 300, a battery pack 200 fixedly connected to one side of the middle of the frame 100, and a fertilizer hopper 500 fixedly connected to the other side of the middle of the frame 100. It also includes: The reverse auger mechanism 600 is located on the upper side of the fertilizer hopper 500. Chain conveyor mechanism 700, which is located below fertilizer hopper 500; The reverse auger mechanism 600 includes a pair of rotating rods 660 rotatably connected to both sides of the fertilizer hopper 500. One side of each rotating rod 660 is fixed with a spiral blade 670, and the other side of each rotating rod 660 is fixed with a lever 680. Both sides of the fertilizer hopper 500 are provided with a discharge port 650.

[0021] The above-mentioned design employs the following structure: The cab 800 mainly consists of a signal transceiver, controller, joystick, seat, and canopy, used to control the movement of the device. The track assembly 300 mainly consists of tracks, traveling wheels, support rollers, tension rollers, and servo motors, used to drive the device to move within the tea garden. The trenching assembly 400 mainly consists of a cylinder, push plate, grooving cutter, and discharge guide plate, used for real-time trenching and fertilization during movement. The push plate is rotatably connected to the grooving cutter, and the tail of the grooving cutter is also rotatably connected to the discharge guide plate. Therefore, the push plate can be adjusted up and down by the cylinder, thereby changing the depth of the grooving cutter head and creating trenches of appropriate depth. The frame 100 serves as the basic support, while the cab 800 on top provides a comfortable control environment for the operator. The track assembly 300 at the bottom gives the machine good ground adaptability and stability, while the trenching assembly 400 connected to its end allows for real-time trenching before fertilization. The battery pack 200 and fertilizer hopper 500 are fixedly connected to both sides of the middle of the frame 100, providing continuous power support and fertilizer storage for the equipment. The reverse auger mechanism 600, located above the fertilizer hopper 500, effectively pushes fertilizer from the hopper to the discharge port 650 through the cooperation of a pair of rotating rods 660 and spiral blades 670, ensuring continuous fertilizer flow. The chain conveyor mechanism 700 below is responsible for transporting fertilizer from the discharge port 650 to the fertilization position, achieving precise fertilization. The coordinated operation of these components not only improves fertilization efficiency but also ensures a smooth and reliable fertilization process.

[0022] like Figures 7 to 11As shown, the reverse auger mechanism 600 also includes protective shells 610 fixed to both sides of the fertilizer hopper 500. A dual-head motor 620 is fixedly connected to the inner cavity of each protective shell 610. A first gear 630 is fixedly connected to the first output end of each dual-head motor 620. Two first gears 630 are provided, and both first gears 630 mesh with a first chain 640. The sidewall of the first gear 630 is fixedly connected to the end of a rotating rod 660. An eccentric wheel 6130 is fixedly connected to the end of the rotating rod 660 near the lever 680. The sidewall of the eccentric wheel 6130 is rotatably connected to a connecting rod. Rod 6120; the end of rod 6120 away from eccentric wheel 6130 is rotatably connected to slide plate 6110, slide plate 6110 is slidably connected to the side wall of fertilizer hopper 500 via slide rail 6100; brackets 690 are fixed to both sides of slide rail 6100, brackets 690 are U-shaped and are snapped into the side wall of fertilizer hopper 500; a conical panel 6140 is fixed to the inner side of bracket 690, an arc-shaped pressure plate 6150 is fixed to the bottom of conical panel 6140, and both conical panel 6140 and arc-shaped pressure plate 6150 slide against the inner wall of fertilizer hopper 500.

[0023] The above scheme employs a method where levers 680 are arranged at different angles to enhance the dispersing effect. The first gear 630, driven by a dual-head motor 620, and the first chain 640 mutually drive each other, causing the rotating rod 660 to rotate. During the rotation of the rotating rod 660, it synchronously drives the spiral blades 670 and the levers 680 to rotate together. At this time, loose fertilizer can enter the discharge port 650 through the gaps between the spiral blades 670, while large pieces of compacted fertilizer are pushed in the opposite direction by the spiral blades 670 and moved to the position of the levers 680. As the levers 680 rotate continuously, they disperse the compacted fertilizer. Through this series of actions, all the fertilizer can eventually enter the discharge port 650 smoothly, preparing for subsequent fertilization. The next process involves the rotating rod 660 also synchronously driving the rotation of the eccentric wheel 6130. The movement of the eccentric wheel 6130 causes the end of the connecting rod 6120 to move back and forth continuously, thereby enabling the slide plate 6110 to slide back and forth on the slide rail 6100. This design not only enhances the dynamic performance of the equipment but also improves fertilization efficiency. The movement of the sliding plate 6110 further drives the support 690 to reciprocate up and down, causing the inner conical plate 6140 to reciprocate at the corner of the fertilizer hopper 500. The advantage of this design is that the bottom curved pressure plate 6150 can move up and down accordingly, effectively twisting and crushing the compacted fertilizer in the area of ​​the lever 680, thereby enhancing the dispersing effect and ensuring that the fertilizer flows more evenly into the discharge port 650. Waste falling onto the surface of the conical plate 6140 can also slide down the slope. This effectively avoids the problem of fertilizer splashing outside the fertilizer hopper 500 due to impact when the lever 680 processes compacted fertilizer. Through precise mechanical coordination, the entire fertilization process becomes more efficient and stable.

[0024] like Figures 2 to 7 As shown, the chain conveyor mechanism 700 includes a support frame 710 fixed to the bottom of the fertilizer hopper 500, a second gear 730 fixed to the second output end of the dual-head motor 620, and two second gears 730 are provided; the two second gears 730 mesh together with a second chain 740, a conveying component 720 fixed to the side wall of the second gear 730, and the conveying component 720 is set on the support frame 710; multiple U-shaped plates 750 are fixedly fixed at equal intervals on the surface of the conveying component 720, and an arc plate 760 is fixedly fixed in the middle of each U-shaped plate 750; a discharge baffle 780 is rotatably connected to the bottom of the fertilizer hopper 500, and grooves are provided on both sides of the arc plate 760, the depth of which is adapted to the side wings of the discharge baffle 780; a torsion spring 770 is sleeved on the outer wall of the fertilizer hopper 500 through a small shaft, and the end of the torsion spring 770 abuts against the side wall of the discharge baffle 780.

[0025] The above-mentioned scheme employs a conveyor 720, primarily composed of a belt chain and a rotating shaft, which continuously conveys fertilizer in a U-shape. Fertilizer entering the discharge port 650 falls evenly onto the surface of the dual-head motor 620. Multiple equally spaced arc-shaped plates 760 evenly separate the fertilizer, ensuring consistent application. When the fertilizer reaches the discharge baffle 780, the baffle, through its leveling function, smooths the surface of the fertilizer separated by the arc-shaped plates 760, ensuring relatively uniform fertilizer volume in the intervals and preventing accumulation. This design not only improves the accuracy of fertilization but also ensures the rational use of fertilizer and reduces waste. During fertilization, the equipment may encounter larger stones or debris; in this case, the discharge baffle 780 plays a crucial role. Under the action of the torsion spring 770, the stones can smoothly squeeze and push aside the discharge baffle 780 and deflect the torsion spring 770, thus preventing system blockage. Torsion springs 770 are installed on both sides of the discharge baffle 780, providing pre-tension to the baffle. The discharge baffle 780 will only be pushed open when the external force exceeds this pre-tension. This design ensures that the equipment can automatically adapt to environmental changes and maintain smooth operation during fertilization. In summary, this pure electric ride-on tracked fertilizer applicator for tea gardens forms a complete and efficient fertilization system through the coordinated efforts of each step, from trenching and fertilizer dispersal to uniform application. This not only improves the efficiency and accuracy of fertilization but also helps reduce labor costs and enhances the overall management level of the tea garden.

[0026] Working principle and usage process of this invention: First, the device moves via the track assembly 300 and digs trenches using the trenching assembly 400. During the trenching and fertilization process, the fertilizer may clump, so a reverse auger mechanism 600 is needed to break it up. The operator pushes a lever, which sends a signal to the controller to activate the dual-head motor 620. The first gear 630 and the first chain 640 drive each other, causing the rotating rod 660 to rotate. During the rotation of the rotating rod 660, the spiral blades 670 and the lever 680 are driven to rotate synchronously. Loose waste material can enter the discharge port 650 through the gaps in the spiral blades 670, while large pieces of clumped fertilizer are pushed in the reverse direction by the spiral blades 670 to the position of the lever 680. As the lever 680 rotates, the clumps are broken up and finally enter the discharge port 650. Secondly, as the rotating rod 660 rotates, it can also drive the eccentric wheel 6130 to rotate simultaneously. The eccentric wheel 6130 then pulls the end of the connecting rod 6120 to rotate back and forth. Through the other end of the connecting rod 6120, the sliding plate 6110 can slide back and forth on the slide rail 6100. The sliding plate 6110 continues to drive the bracket 690 to move up and down back and forth, so that the inner connected conical plate 6140 also moves back and forth at the corner of the fertilizer hopper 500. This allows the bottom arc-shaped pressure plate 6150 to press down back and forth, crushing the clumped fertilizer in the area of ​​the lever 680 with the twisting and crushing of the lever 680, enhancing the dispersing effect and effectively preventing the lever 680 from hitting and splashing the fertilizer out of the fertilizer hopper 500. Finally, the fertilizer entering the discharge port 650 falls onto the surface of the conveyor 720. Multiple equally spaced arc-shaped plates 760 evenly separate the fertilizer, and upon reaching the discharge baffle 780, the baffle smooths the surface of the fertilizer separated by the arc-shaped plates 760, ensuring that the waste volume in the interval area is relatively uniform and preventing accumulation. When encountering relatively large stones, the discharge baffle 780 is pushed aside by the torsion spring 770, deflecting the torsion spring 770 and preventing blockage. The torsion springs 770 are installed on both sides of the discharge baffle 780, providing preload; only when the preload is exceeded can the discharge baffle 780 be pushed open.
