Description

Technical Field

[0001] This invention relates to the field of agricultural fertilization equipment technology, and in particular to a soil fertilization device suitable for eggplant cultivation. Background Technology

[0002] Currently, fertilizer application in eggplant cultivation is generally carried out using the hole application method. Hole application requires digging a fertilization hole at a suitable location around the plant's root zone, placing a measured amount of solid fertilizer at the bottom of the hole, and then backfilling and covering it to complete the fertilization operation. However, in large-scale planting scenarios, the highly repetitive nature of individual plant operations and the cumbersome workflow significantly increase time and labor costs. Furthermore, prolonged, frequent bending over can easily lead to lower back fatigue and cumulative strain on operators, thus limiting production efficiency. Summary of the Invention

The motor drives the first gear, which is driven and connected to the meshing end to drive the turning shovel to swing.

[0011] Furthermore, there are two of each of the soil-turning shovels and the first pivot joint. The two soil-turning shovels and the two first pivot joints are distributed on opposite sides of the frame and spaced apart along the width direction of the frame.

[0012] Furthermore, the two turning shovels are respectively a first turning shovel and a second turning shovel. A second gear is provided between the second turning shovel and the lifting drive mechanism. The second gear is connected to the meshing end of the second turning shovel and the first gear respectively.

[0016] Furthermore, at least two of the first feed inlet, the second feed inlet, and the guide tube are provided, and the guide groove is provided with a partition, which divides the guide groove into two cavities.

[0017] Furthermore, the vehicle frame is also equipped with a scraper, and the soil-turning shovel, the guide tube, and the scraper are arranged sequentially along the moving direction of the vehicle frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See Figures 1-4 A preferred embodiment of the present invention provides a soil fertilization device suitable for eggplant cultivation, comprising: a frame 1, a soil turning shovel 4, and a fertilization device.

[0031] The frame 1 is equipped with a walking mechanism 2 and a handle 3, and the frame 1 is supported by the walking mechanism 2; the handle 3 is used for gripping and facilitating the movement of the frame 1. The frame 1 serves as an integral load-bearing structure, on which the mechanisms for travel and operation are mounted. The walking mechanism 2 consists of wheel sets and their matching transmission components, providing ground support and movement functionality for the frame 1; the operation mechanism is a push-pull handle 3 or a direction control lever, whose design and arrangement facilitate the operator to apply pushing or traction force and to control the direction and speed of the equipment's movement, thereby driving the entire machine to move smoothly along a predetermined path, thus meeting the positioning and transfer requirements for field operations.

[0032] The bottom of the turning shovel 4 is a digging section 401, which is used to embed into the soil to dig trenches during the movement of the vehicle frame 1. The vehicle frame 1 is equipped with a lifting drive mechanism 5, and the turning shovel 4 is connected to the output of the lifting drive mechanism 5 so that it can be driven by the output to make the digging section 401 sink into or detach from the soil. The digging section 401 is located at the bottom of the turning shovel 4 and is used to cut into the soil during the movement of the equipment, and to strip the soil and dig trenches through its specific shape. The turning shovel 4 is connected to the output of the lifting drive mechanism 5 on the vehicle frame 1. With the driving action of this mechanism, the turning shovel 4 can achieve vertical displacement, thereby realizing the sinking or detaching action of the digging section 401. In the working state, as the vehicle continues to move forward, the turning shovel 4 maintains a certain depth of insertion into the soil, continuously lifting the soil in the area in front of it and diverting it to both sides, thereby forming a continuous and regularly shaped trench. The lifting drive mechanism 5 can control the soil turning shovel 4 to enter and exit the soil to adjust the longitudinal extension length of the trench. It can also adjust the working depth of the soil turning shovel 4 to control the trench excavation depth and meet the fertilization depth requirements under different planting periods.

[0033] The fertilization device is installed on the frame 1. The device includes a storage tank 6 and a guide pipe 7. The storage tank 6 has a receiving cavity 8 for holding fertilizer. The guide pipe 7 connects to the receiving cavity 8 and guides the fertilizer from the receiving cavity 8 to the trench excavated by the excavation unit 401. The storage tank 6 has a sealed receiving cavity 8 for storing solid granular fertilizer or pre-dissolved liquid fertilizer, possessing a certain capacity and corrosion resistance. The guide pipe 7 connects to the outlet of the storage tank 6, forming a continuous fertilizer delivery path that stably guides the fertilizer into the trench excavated by the tillage shovel 4. The guide pipe 7 adopts a directional outlet design, with its output end extending precisely towards the trench position. This allows for continuous and even application of fertilizer into the trench during the continuous movement of the equipment, achieving efficient fertilization operations synchronized with trenching. During operation, it works in conjunction with the tillage shovel 4 to ensure accurate placement and coverage of fertilizer within the trench.

[0034] Working Principle: During operation, the traveling mechanism 2 of the chassis 1 facilitates the movement of the device. The turning shovel 4, controlled by the lifting drive mechanism 5, can move upwards or downwards to cut into the soil at a preset depth. As the chassis 1 continues to move forward, its digging section 401 continuously lifts the soil in front and diverts it to both sides, thus forming a continuous and regular trench. The lifting drive mechanism 5 can dynamically adjust the soil penetration depth and lifting timing of the turning shovel 4, thereby controlling the depth and longitudinal extension length of the trench. Simultaneously, the fertilization device installed on the chassis 1 operates synchronously: solid or liquid fertilizer in the storage tank 6 is stably guided through the guide pipe 7 and accurately placed into the newly excavated trench, achieving integrated continuous operation of trenching and fertilization.

[0035] Clearly, the walking mechanism 2, composed of wheel sets and its matching transmission system, undertakes the functions of supporting and moving the entire machine. By controlling the speed and direction of travel, it drives the equipment to move stably along a predetermined path, meeting the requirements of precise field operations and workstation transfers. The tilling shovel 4 achieves precise vertical displacement control through the lifting drive mechanism 5. It can adjust the soil penetration depth and working state according to different crop types and agronomic needs, thereby forming trenches with adjustable depth and length, enhancing the targeting and adaptability of fertilization operations. The fertilization device adopts a directional flow guidance structure, which can accurately deliver fertilizer into the trench, reducing waste during the spreading process, improving fertilizer utilization, and achieving concentrated supply of nutrients to the crop root zone, further enhancing the fertilization effect.

[0036] In this embodiment, preferably, the frame 1 is provided with a first pivot member 9, and the rod portion 402 of the tilling shovel 4 is provided with a second pivot member 10. The first pivot member 9 and the second pivot member 10 are pivotally connected, so that the tilling shovel 4 can swing upward or downward relative to the frame 1. The frame 1 is equipped with the first pivot member 9, and the rod portion 402 of the tilling shovel 4 is fixed at a corresponding position with the second pivot member 10. The two form a reliable pivot connection, giving the tilling shovel 4 the freedom to rotate around the pivot center, allowing it to swing upward or downward relative to the frame 1. This pivot structure is the key mechanism for realizing the changing working posture of the tilling shovel 4. By driving the tilling shovel 4 to swing downward, the digging part 401 can effectively cut into the soil, and swinging upward, it can completely detach from the cultivated layer, thereby precisely controlling the start and end positions of the trench and realizing flexible adjustment of the trench length. Furthermore, this structure also supports a mode where the tilling shovel 4 can be rapidly lifted after cutting into the soil, thereby excavating independent pits in the field to meet differentiated agronomic needs such as targeted fertilization. The entire hinge and drive system work in tandem, significantly enhancing the equipment's adaptability and control precision to complex operational requirements.

[0037] In this embodiment, preferably, the end of the turning shovel 4 furthest from the digging section 401 is the meshing end 403. The meshing end 403 has a fan-shaped structure with transmission teeth. The transmission teeth are driven by the lifting drive mechanism 5 to drive the turning shovel 4 to swing. The drive device includes a motor and a first gear 11. The motor drives the first gear 11, which is driven by the meshing end 403 to drive the turning shovel 4 to swing. The meshing end 403 of the turning shovel 4 has a fan-shaped structure with continuously distributed transmission teeth machined on its outer edge. The lifting drive mechanism 5 includes a motor and a first gear 11 driven directly or indirectly by the motor output shaft. The first gear 11 meshes with the transmission teeth on the meshing end 403 to form a complete gear transmission system. When the motor is running, the power is transmitted to the turning shovel 4 through the meshing action of the first gear 11 and the fan-shaped transmission teeth, thereby driving it to make a precise swinging motion around the pivot point. By changing the rotation direction of the motor, the soil-turning shovel 4 can be controlled to swing up or down, thereby enabling the excavation unit 401 to perform orderly digging or detaching from the soil, and to accurately control the trench excavation depth, length and pit excavation mode.

[0038] In this embodiment, preferably, two tilling shovels 4 and two first pivot joints 9 are provided. The two tilling shovels 4 and the two first pivot joints 9 are distributed on opposite sides of the frame 1 and spaced apart along the width direction of the frame 1. Two sets of first pivot joints 9 and corresponding tilling shovels 4 are symmetrically arranged on both sides of the frame 1. The two sets of first pivot joints 9 are respectively fixed to the left and right main structures of the frame 1, and their positions can ensure the force balance and movement stability of the tilling shovels 4 during operation. Each tilling shovel 4 is pivotally connected to the first pivot joint 9 on the frame 1 through the second pivot joint 10 of its rod 402, so that the tilling shovels 4 on both sides can swing independently or synchronously around the hinge point. The digging parts 401 of the two tilling shovels 4 maintain a certain interval in the width direction of the frame 1. This interval can be designed or adjusted according to the planting row spacing of the eggplant crop. The lifting drive mechanism 5 drives the fan-shaped meshing ends 403 of the tilling shovels 4 on both sides simultaneously or separately through the transmission system to control the swing angle and direction. During operation, the equipment moves along the rows of crops, and the two side shovels 4 swing down synchronously under the action of the drive mechanism and cut into the soil, completing the trenching or pit digging operation as the frame 1 moves forward. This dual-sided symmetrical operation mode allows the equipment to complete the digging of fertilization pits or trenches for two rows of crops in one stroke, which significantly improves the operation efficiency, reduces the number of trips to the field, reduces energy consumption and soil compaction, and is suitable for efficient fertilization operations in large-scale planting models.

[0039] In this embodiment, preferably, the two turning shovels 4 are a first turning shovel 4 and a second turning shovel 4. A second gear 12 is provided between the second turning shovel 4 and the lifting drive mechanism 5. The second gear 12 is connected to the meshing end 403 of the second turning shovel 4 and the first gear 11 respectively. The first turning shovel 4 and the second turning shovel 4 are symmetrically arranged on both sides of the frame 1. The second gear 12 is added between the second turning shovel 4 and the lifting drive mechanism 5. This gear meshes with the transmission teeth of both the first gear 11 and the meshing end 403 of the second turning shovel 4, forming a series transmission structure. When the motor drives the first gear 11, the power is directly transmitted to the first turning shovel 4 on the one hand, and indirectly transmitted to the second turning shovel 4 through the second gear 12 on the other hand, thereby realizing synchronous driving of the two. This transmission scheme ensures that the two turning shovels 4 always maintain the same swing direction and angle during operation, and can swing down synchronously to cut the soil or lift up synchronously to remove the topsoil. It realizes symmetrical excavation of trenches or fertilization pits on both sides, effectively ensuring the consistency of the operation form and improving the digging accuracy and operation efficiency.

[0040] In this embodiment, preferably, the frame 1 is provided with a plurality of elastic elements 13, which are respectively located below the turning shovel 4, and have a tendency to drive the turning shovel 4 to rotate upward. One end of the elastic element 13 is fixed to the frame 1, and the other end acts on the rod 402 of the turning shovel 4. Its elastic force always acts in the direction that resists the downward swing of the turning shovel 4, thereby providing a continuous upward reset tendency for the turning shovel 4. After the digging operation is completed, the lifting drive mechanism 5 is unloaded, and the elastic stored energy is released, assisting the turning shovel 4 to quickly and reliably rotate upward, so that its digging part 401 is completely removed from the soil and returns to the transport posture. This design effectively avoids the situation where the turning shovel 4 accidentally enters the soil due to its own weight or vibration when the equipment is not in operation, improves the passability and safety during the movement of the equipment, and reduces unnecessary movement resistance and mechanical wear.

[0041] In this embodiment, preferably, the receiving cavity 8 is provided with a metering device 14, which includes a pivot shaft 1401, a metering box 1402, and a metering disc 1403. The pivot shaft 1401 is connected to the inner wall of the storage box 6 and passes through the metering box 1402. A first inlet 15 is provided below the metering box 1402, and a first outlet 16 is provided above the metering box 1402. The metering disc 1403 is pivotally connected to the pivot shaft 1401 so that the metering disc 1403 can rotate around the pivot shaft 1401. The metering disc 1403 is disposed inside the metering box 1402 and has multiple metering grooves distributed circumferentially along the metering disc 1403. The two ends of the pivot shaft 1401 are fixedly installed on the inner wall of the storage box 6, pass through the metering box 1402, and provide stable rotational support for the metering disc 1403 to prevent displacement during operation. The metering box 1402 is a sealed container with a first inlet 15 at the bottom communicating with the receiving cavity 8, and a first outlet 16 at the top communicating with the guide tube 7. A metering disc 1403 is rotatably mounted inside the metering box 1402 via a pivot shaft 1401, with its axis of rotation collinear with the pivot shaft 1401. The disc has multiple uniformly shaped, fixed-volume metering slots evenly distributed circumferentially, used to hold and transfer fertilizer during rotation. During operation, an external drive mechanism continuously rotates the metering disc 1403. When a metering trough rotates with the metering disc 1403 to the first inlet 15, fertilizer is filled into the trough under gravity. As the disc continues to rotate, the metering trough is effectively sealed by the inner wall of the metering box 1402 after leaving the inlet area, preventing fertilizer leakage at non-discharge positions. When the metering trough rotates above the first discharge port 16, its top reopens, and fertilizer falls into the guide pipe 7 under gravity, ultimately being precisely delivered into the trench or pit excavated by the tilling shovel 4. This metering device 14 achieves strict control over the unit amount of fertilizer applied through the geometric volume of the metering trough, effectively avoiding fertilizer waste and uneven application. Furthermore, the amount of fertilizer can be flexibly adjusted by replacing the metering disc 1403 with different metering trough volumes according to different fertilizer application requirements. This helps ensure that each crop receives a uniform fertilizer supply, thereby significantly improving the accuracy of fertilization operations and the consistency of crop growth and development.

[0042] In this embodiment, preferably, the first discharge port 16 of the metering device 14 abuts against the second inlet of the guide tube 7. The second inlet is provided with a guide groove 17, which is used to guide solid fertilizer into the guide tube 7. The first discharge port 16 and the second inlet are in close contact, forming a continuous and reliable fertilizer conveying channel. The inlet of the second inlet is designed with a tapered guide groove 17, the inner wall of which is smoothed and the cross-sectional shape matches the fertilizer flow discharged from the metering disc 1403. This effectively receives the solid granular fertilizer falling from the first discharge port 16 and smoothly guides it into the internal channel of the guide tube 7. This significantly reduces the risk of fertilizer blockage or adhesion at the junction, ensuring the continuity and stability of the solid fertilizer conveying process, thereby improving the operational reliability of the entire fertilization system.

[0043] In this embodiment, preferably, at least two first inlet 15, two second inlet, and guide pipe 7 are provided. The guide channel 17 is provided with a partition 18, which divides the guide channel 17 into two cavities. Two sets of the first inlet 15, the second inlet, and the guide pipe 7 are symmetrically arranged, corresponding to the fertilization needs on both sides respectively. A partition 18 is provided inside the guide channel 17, dividing the inner cavity of the guide channel 17 into two independent cavities, forming a non-interfering dual-cavity structure. Each cavity is connected to the first inlet 15, the first outlet 16, the second inlet, and the guide pipe 7 on the same side, forming a complete single-sided fertilizer flow path. This design enables independent dual-path fertilizer delivery, operating synchronously during work. It can accurately and evenly distribute fertilizer into the excavated pits or ditches on both sides, effectively avoiding mutual interference and uneven fertilizer distribution during the dual-sided fertilization process, significantly improving work efficiency and fertilization accuracy.

[0044] In this embodiment, preferably, the frame 1 is further provided with a scraper 19, and the turning shovel 4, the guide pipe 7, and the scraper 19 are arranged sequentially along the moving direction of the frame 1. The turning shovel 4 is responsible for excavating trenches or pits, the guide pipe 7 puts a measured amount of fertilizer into them, and then the scraper 19 backfills and levels the soil brought out and piled around the trenches or pits during the excavation process. More preferably, the scraper 19 is made of flexible material, or forms a flexible structure by combining hinges and elastic elements, so that it can adapt to soil of different heights and pile shapes, effectively covering the soil and leveling the surface during the backfilling process, thereby further improving the surface flatness and work quality after fertilization.

[0045] In this embodiment, preferably, the bottom of the storage box 6 is designed as a sloping structure with a lower center and higher sides. This shape helps the fertilizer inside the box to automatically gather in the central area by gravity, thereby ensuring that the fertilizer flows continuously and smoothly to the feed inlet of the metering device 14 located in the center of the bottom of the box. This design effectively reduces fertilizer residue in the box, avoids blockage or interruption of material flow caused by local accumulation, and improves the reliability and stability of metering.

[0046] In this embodiment, preferably, the walking mechanism 2 of the frame 1 is equipped with an independent power source to drive the entire machine. The frame 1 integrates a control system, which is electrically connected to the power source of the walking mechanism 2, the lifting drive motor of the tilling shovel 4, and the drive mechanism of the quantitative disc 1403 through electrical lines, so as to realize centralized control and collaborative operation management of key parameters such as equipment movement, digging depth, and fertilizer application rate.
