Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a bio-organic fertilizer applying device for eggplant planting. Background Art

[0002] The rational application of bio-organic fertilizer during the eggplant planting process is a key agricultural technical measure to ensure the healthy growth of eggplant and achieve high yield and high quality. It not only provides necessary nutrients for eggplant, but also improves soil fertility, which is crucial in the growth process of eggplant.

[0003] Existing eggplant fertilization generally adopts two forms: underground fertilization and foliar spraying. Foliar fertilization generally applies swelling agents or liquid foliar organic fertilizers during the eggplant fruit setting and swelling period. However, foliar fertilization is inconvenient to control and the fertilization workload is large. At the same time, the retention time of the sprayed foliar organic fertilizer is short and it is greatly affected by the external environment. The fertilization effect is inconvenient to control. Foliar fertilization cannot improve the soil and requires multiple fertilizations, which increases the workload. Underground fertilization is generally carried out near the roots of the eggplant plants at a specific time. The applied biological organic fertilizer is slowly released after being buried underground, improving the soil and taking effect for a long time. However, the digging, fertilizing and covering of the soil in the fertilization process are carried out separately, which increases the construction steps and makes it inconvenient to control the amount of fertilizer, resulting in uncontrolled fertilizer effect, which affects the fertilizer effect.

[0032] The fertilizer pipe 3 includes a fixed pipe 32 and a lifting pipe 33 which are correspondingly arranged and connected to each other.

[0033] The traveling vehicle 1 is provided with a driving assembly, which is connected to the fertilizing head 31 through a transmission assembly arranged along the fixed pipe 32 .

[0034] The present invention discloses a bio-organic fertilizer application device for eggplant planting, which realizes mobile fertilization through a walking vehicle 1, integrates multiple functions such as walking, fertilizer storage, mixing, material guiding, and fertilizing, has a high degree of automation, replaces the traditional tedious operations of manual digging, fertilizing, covering with soil, and realizes the integrated operation from bio-organic fertilizer storage to fertilization, so that the fertilization process does not need to be separately dug and covered with soil, simplifies the fertilization process, reduces manual intervention, improves fertilization efficiency, and reduces labor intensity; a mixing component is arranged in the fertilizer storage tank 2, which can fully mix the bio-organic fertilizer before fertilization, avoids uneven composition of the bio-organic fertilizer, ensures consistency of fertilization effect and maximizes fertilizer efficiency; through the cooperation of the fertilizer storage tank 2, the material guiding component and the fertilizer pipe 3, the driving component and the transmission component drive the fertilizer head 31 to rotate, thereby realizing the synchronous digging and fertilizing, and realizing quantitative and fixed-point application of the bio-organic fertilizer. , avoids the problem of inconvenient fertilizer amount control caused by digging holes, covering soil and other links in traditional underground fertilization, thereby realizing accurate control of fertilizer amount, fertilizer application position and fertilizer application depth, and improving the stability of fertilization effect; the lifting tube 33 can be lifted and lowered longitudinally at the bottom of the traveling vehicle 1, and the fertilizer head 31 can be rotatably connected, so that it can adapt to eggplant plants of different heights and complex field terrains, ensuring that the bio-organic fertilizer can be accurately applied near the roots of the eggplant, thereby improving the flexibility and adaptability of fertilization; during the fertilization process, the fertilizer head 31 drills into the ground to send the bio-organic fertilizer into the ground and mix it with the soil, which can not only provide necessary nutrients for the eggplant, but also improve soil fertility, loosen the soil, promote the healthy growth of eggplant, and achieve high-quality and high-yield eggplant; at the same time, the device can control the application process and effect of the bio-organic fertilizer, avoid waste of bio-organic fertilizer and environmental pollution, and improve the economy and environmental protection of the use of bio-organic fertilizer. The present invention has a simple structure and is easy to use. It can complete the fertilization of eggplants at one time without manual trenching and soil filling, thus realizing mechanized, precise and automated fertilization, and significantly improving the application efficiency and effect of biological organic fertilizers in eggplant planting.

[0035] In one embodiment of the present invention, the fertilizer pipe 3 is divided into a fixed pipe 32 and a lifting pipe 33. The lifting pipe 33 is raised and lowered at the bottom of the traveling vehicle 1, which can drive the fertilizer head 31 to rise and fall, making it convenient to insert the fertilizer head 31 into the ground to fertilize the fertilization site; at the same time, the fertilizer head 31 can be conveniently lifted to separate from the ground when no fertilizer is applied, so as to prevent it from affecting the movement of the traveling vehicle 1.

[0036] In one embodiment of the present invention, the walking vehicle 1 of this embodiment includes a body 11, the fertilizer storage tank 2 and the fertilizer pipe 3 are both arranged on the body 11, and a plurality of walking wheels 13 are provided at the bottom end of the body 11 for convenient walking; a handle 12 is provided at one end of the body 11 for conveniently pushing the body 11 to walk.

[0037] In one embodiment of the present invention, the running wheel 13 of this embodiment can be configured to be electrically driven or driven by other power sources, which can reduce the driving difficulty.

[0038] In one embodiment of the present invention, the fertilizer storage tank 2 is fixed to the vehicle body 11 via a plurality of supporting legs 25 .

[0039] In one embodiment of the present invention, a control panel may be provided on the handle 12 of this embodiment to control all actions of the device.

[0040] In one embodiment of the present invention, a controllable control valve 27 is provided in the fertilizing pipe 3 to control the movement of the bio-organic fertilizer.

[0041] In one embodiment of the present invention, the mixing assembly includes a mixing motor 22 mounted on a feed hopper 24 in the air through a mounting frame 212. The output shaft of the mixing motor 22 extends downward into the fertilizer storage tank 2 and is transmission-connected to a mixing shaft 21. A plurality of mixing rods 23 are fixed to the side wall of the mixing shaft 21. The mixing motor 22 drives the mixing shaft 21 to rotate, and then the biological organic fertilizer is mixed through the mixing rods 23, and the agglomerated biological organic fertilizer is crushed at the same time.

[0042] A further optimized solution includes a guide tube 26 disposed on the traveling vehicle 1, the guide tube 26 being connected between the bottom end of the fertilizer storage tank 2 and the fixed tube 32; a conveying assembly for controlling the efficiency of organic fertilizer delivery is rotatably connected within the guide tube 26, and the conveying assembly is in driving connection with the fixed shaft 36. The guide tube 26 is connected between the fertilizer storage tank 2 and the fixed tube 32, facilitating the movement of the bio-organic fertilizer and its delivery into the fertilization tube 3; when the bio-organic fertilizer, evenly mixed in the fertilizer storage tank 2, is delivered from the bottom end into the guide tube 26, it is then delivered to the fixed tube 32 via the conveying assembly; at the same time, because the conveying assembly is driven by the drive assembly, the need for a power source is reduced, and the conveying assembly and the drive assembly are interlocked, allowing for simultaneous digging and fertilizing, facilitating precise control of the amount of fertilizer applied, and blocking the delivery of organic fertilizer between the guide tube 26 and the fixed tube 32 when digging is not in progress.

[0043] A further optimized solution includes a through hole 14 extending through the trolley 1. A fixed tube 32 extends into and is fixedly connected to the through hole 14. The top end of the lifting tube 33 is slidably connected within the through hole 14. A lifting assembly is provided between the lifting tube 33 and the bottom end of the trolley 1. The through hole 14 facilitates the passage of the bio-organic fertilizer without affecting the raising and lowering of the lifting tube 33, ensuring the normal passage of the bio-organic fertilizer.

[0044] A further optimization scheme includes a lifting assembly comprising several lifting rods 34 fixed to the bottom end of the vehicle 1 and arranged at equal intervals around the circumference of the lifting tube 33. A common connecting ring 35 is fixed to the bottom ends of the lifting rods 34. The connecting ring 35 is sleeved and fixed to the outer wall of the lifting tube 33 and slidably connected to the fertilizer head 31. The lifting rods 34 are synchronized and move in unison, driving the connecting ring 35 to rise and fall, which in turn drives the lifting tube 33 and, in turn, the fertilizer head 31. The connecting ring 35 is also slidably connected to the top of the fertilizer head 31, ensuring that the rotation and elevation of the fertilizer head 31 are independent and do not affect each other.

[0045] In one embodiment of the present invention, an annular guide groove 322 is formed at the bottom end of the connecting ring 35 , and a guide block 323 is slidably connected in the guide groove 322 for limiting and fixing the fertilizing head 31 .

[0046] In one embodiment of the present invention, the top end of the lifting tube 33 is configured to be inclined, which can prevent the bio-organic fertilizer from accumulating on the top end of the lifting tube 33 .

[0047] A further optimized solution includes a transmission assembly that is transmission-connected to the drive assembly. The fixed shaft 36 is arranged along the axis of the fixed tube 32 and extends into the lifting tube 33. The fixed shaft 36 is transmission-connected to a movable shaft 37, which slides longitudinally at the bottom end of the fixed shaft 36 and is transmission-connected to the fertilizer head 31. A prismatic transmission hole 319 is provided at the bottom end of the fixed shaft 36. A transmission rod 318 is slidingly connected within the transmission hole 319. The bottom end of the transmission rod 318 is fixedly connected to the top end of the movable shaft 37. When the fertilizer head 31 is raised or lowered, the transmission rod 318 is driven to slide within the transmission hole 319, thereby achieving follow-up adjustment of the length of the entire transmission control assembly. At the same time, the transmission hole 319 and the transmission rod 318 are prismatic in design, so that they can only be raised and lowered without relative rotation, allowing transmission to occur during the raising and lowering process.

[0048] In one embodiment of the present invention, a support spring 320 is fixed between the fixed shaft 36 and the movable shaft 37. The support spring 320 is sleeved outside the transmission rod 318 to ensure that the fixed shaft 36 and the movable shaft 37 rebound and reset when no external force is applied.

[0049] A further optimized solution is that the conveying assembly includes a spiral conveying shaft 28 that is transmission-connected to the fixed shaft 36. A conveying block 29 corresponding to the top of the fixed tube 32 is sleeved and fixed on the spiral conveying shaft 28. The outer wall of the conveying block 29 is in sliding contact with the inner wall of the guide tube 26. When the spiral conveying shaft 28 rotates, the conveyed organic fertilizer is transferred to the fixed tube 32. The spiral conveying shaft 28 is transmission-connected to the fixed shaft 36. When the fixed shaft 36 rotates, the spirally arranged spiral conveying shaft 28 pushes the falling organic fertilizer toward the conveying block 29, and the organic fertilizer is transferred into the fixed tube 32 through the conveying block 29, thereby controlling the organic fertilizer to enter the fixed tube 32 and controlling the transfer timing of the organic fertilizer, thereby avoiding the waste and blockage of biological organic fertilizer, improving the fertilization efficiency, ensuring the continuous and stable fertilization process, and avoiding the impact of poor fertilizer supply on the fertilization effect.

[0050] A further optimization scheme is to provide a plurality of equally spaced conveying troughs 210 on the outer wall of the conveying block 29. The conveying troughs 210 extend through the end of the conveying block 29 toward the end of the spiral conveying shaft 28, and the other end of the conveying troughs 210 extends above the fixed tube 32. The plurality of conveying troughs 210 are arranged in a spiral shape and at equal intervals around the outer wall of the conveying block 29. When misaligned with the entrance of the fixed tube 32, a closed cavity is formed between the conveying troughs 210 and the inner wall of the guide tube 26, facilitating the storage of organic fertilizer. When the conveying block 29 rotates to the corresponding position, the conveying troughs 210 align with the top of the fixed tube 32, allowing the stored organic fertilizer to fall into the fixed tube 32, thereby transferring the organic fertilizer.

[0051] In one embodiment of the present invention, the fixed shaft 36 is divided into two independent sections based on the axis of the spiral conveying shaft 28. The two ends of the fixed shaft 36 are respectively connected to the symmetrically arranged driving gear 38 and the driven gear 310, and the driving gear 38 and the driven gear 310 are isolated and disconnected; and the spiral conveying shaft 28 is connected to the transmission gear 311, which is respectively engaged with the driving gear 38 and the driven gear 310 for transmission, thereby realizing power transmission between the fixed shaft 36 and the spiral conveying shaft 28.

[0052] In one embodiment of the present invention, the spiral conveying shaft 28 is disconnected from the corresponding positions of the driving gear 38 and the driven gear 310, and the two ends are connected by a linkage rod 211, so as to avoid affecting the transmission of the driving gear 38 and the driven gear 310, and also support the stable rotation of the spiral conveying shaft 28.

[0053] In one embodiment of the present invention, a spiral piece 39 is provided on the fixed shaft 36, and the spiral piece 39 is arranged corresponding to the through hole 14 to achieve the closure of the through hole 14. The biological organic fertilizer can only fall when the spiral piece 39 rotates, so that the spiral piece 39 can control the speed of the biological organic fertilizer falling and avoid waste halfway.

[0054] To further optimize the solution, an annular lifting ring 312 is fixedly connected to the inner wall of the lifting tube 33, and the movable shaft 37 passes through the lifting ring 312 and is set with a gap between it and the lifting ring 312; a fixed ring 313 corresponding to the lifting ring 312 is sleeved on the fixed shaft 36, and a gap is set between the outer ring of the fixed ring 313 and the inner wall of the lifting tube 33. When the lifting ring 312 moves with the lifting tube 33, it is detachably connected to the fixed ring 313. The fixing ring 313 and the lifting ring 312 are respectively arranged on the fixing shaft 36 and the lifting tube 33. When the lifting tube 33 is raised, the lifting ring 312 is raised accordingly to abut against the fixing ring 313, blocking the channel so that the biological organic fertilizer cannot pass through. Fertilization can be stopped when the fertilizing head 31 is raised, and the fertilization channel can be blocked in combination with the spiral piece 39 to avoid waste of biological organic fertilizer when no fertilization is performed; and when the fertilizing head 31 is lowered and inserted into the ground, the lifting tube 33 drives the lifting ring 312 to lower, thereby separating the lifting ring 312 from the fixing ring 313, forming a channel for the biological organic fertilizer to pass through, making it convenient for fertilization.

[0055] In one embodiment of the present invention, in order to prevent the accumulation of bio-organic fertilizer on the lifting ring 312 and the fixing ring 313 and prevent the flow from being intercepted, the top of the lifting ring 312 and the top of the fixing ring 313 are both configured as arc-shaped surfaces.

[0056] To further optimize the solution, a fertilizer chamber 314 is provided in the fertilizer head 31, and the lifting tube 33 is connected to the fertilizer chamber 314. The bottom end of the movable shaft 37 extends into the fertilizer chamber 314 and is in transmission connection with the fertilizer chamber 314. The side wall of the fertilizer chamber 314 is provided with a plurality of fertilizer outlet holes 315, and the bio-organic fertilizer delivered into the fertilizer chamber 314 is discharged into the soil through the plurality of fertilizer outlet holes 315. The fertilizer chamber 314 serves as a temporary storage and distribution space for bio-organic fertilizer. The bio-organic fertilizer delivered by the lifting tube 33 is stored in the fertilizer chamber 314, which facilitates the uniform distribution of the bio-organic fertilizer. The plurality of fertilizer outlet holes 315 are provided at the bottom end of the side wall of the fertilizer chamber 314 and are connected to the outside world. When fertilizing, the bio-organic fertilizer is dispersed into the soil to complete the fertilization, avoiding root burn or uneven fertility caused by concentrated fertilization, improving the uniformity of fertilizer efficiency and soil improvement effect, and better meeting the requirements of eggplant growth for the distribution of bio-organic fertilizer.

[0057] In one embodiment of the present invention, the bottom end of the fertilizer distribution chamber 314 is arranged in an outward arc shape, and the arc bottom end is flush with the bottom end of the fertilizer outlet hole 315 to prevent the biological organic fertilizer from remaining.

[0058] In one embodiment of the present invention, a plurality of digging teeth 321 are fixedly connected to the outer wall of the fertilizing head 31. The digging teeth 321 can increase the digging efficiency of the fertilizing head 31, making it convenient for the fertilizing head 31 to be sent underground for fertilizing; at the same time, the soil layer can be softened and the biological organic fertilizer can be mixed with the soil to achieve coverage of the biological organic fertilizer and prevent the volatilization of the biological organic fertilizer. The soil can also be loosened by stirring the soil, thereby improving the growth environment of eggplant.

[0059] In a further optimization scheme, the drive assembly includes a support frame 316 fixed to the vehicle 1 and suspended at the top of the material guide assembly. A drive motor 317 is fixedly mounted at the top of the support frame 316. The output shaft of the drive motor 317 extends downward into the fixed tube 32 and is in driving connection with the fixed shaft 36. The support frame 316 is mounted on the fixed material guide tube 26 to secure it and also supports and fix the drive motor 317. The drive motor 317 is controlled via a control panel on the handle 12, driving the fixed shaft 36 to rotate, providing power for the fertilizing head 31 to apply fertilizer.

[0060] In the embodiment of the present invention, bio-organic fertilizer is a fertilizer with organic matter as the main component and beneficial microorganisms added. It can not only provide the nutrients required for plant growth, but also improve soil structure, enhance soil water retention and air permeability, and promote the growth of plant roots.

[0061] In an embodiment of the present invention, during the growth process of eggplant, according to the actual growth conditions of the plant, the biological organic fertilizer is spread on the soil near the root system of the crop, or the fertilizer is buried around the root system using the "buried application method". This device is a device for the buried application method. By scientifically and rationally applying the biological organic fertilizer, the yield and quality of eggplant can be effectively improved, while reducing dependence on chemical fertilizers and promoting the development of ecological agriculture.

[0062] In the embodiment of the present invention, topdressing is an important step in ensuring healthy plant growth and high yield in eggplant cultivation. Solid organic fertilizer or liquid organic fertilizer can be selected for topdressing. Both have their advantages and disadvantages, and the specific effect depends on the fertilization method, soil conditions and plant needs.

[0063] Solid organic fertilizer: Solid organic fertilizer usually contains rich organic matter and a variety of trace elements, which can provide the comprehensive nutrition needed for eggplant growth. It can slowly decompose in the soil, and the nutrient release is relatively long-lasting, which is suitable for long-term supply. It can improve soil structure, increase soil water retention and air permeability, and help root growth; however, solid organic fertilizer needs to decompose in the soil before it can be absorbed by plants, and the nutrient release rate is relatively slow. Fertilization requires manual spreading or furrow application, and the operation is relatively cumbersome.

[0064] Liquid organic fertilizer: Liquid organic fertilizer can dissolve quickly in water and be quickly absorbed by plants through the root system. It is suitable for quickly replenishing nutrients during the critical growth period. It can be applied through irrigation systems such as drip irrigation and sprinkler irrigation to achieve water and fertilizer integration, save labor, reduce soil salinization, and is suitable for long-term use; however, the production cost of liquid organic fertilizer is relatively high, and the price is more expensive than solid organic fertilizer. It releases nutrients faster, but is not as durable as solid organic fertilizer, and may require more frequent fertilization.

[0065] In terms of application effect, solid organic fertilizer can provide a long-lasting supply of nutrients, which helps to improve the yield and quality of eggplant, while liquid organic fertilizer can quickly supplement nutrients during critical growth periods such as the fruiting period, which can significantly improve fruit quality and yield; long-term use of solid organic fertilizer can improve soil structure and increase soil biological activity, while liquid organic fertilizer can reduce soil salinization and is suitable for long-term use, but the effect on improving soil structure is not as significant as solid organic fertilizer; solid organic fertilizer is relatively cumbersome to apply, but the nutrient release is long-lasting and it is suitable for base fertilizer and long-term topdressing, while liquid organic fertilizer is easy to apply, suitable for rapid application through the irrigation system, and suitable for topdressing during the critical growth period.

[0066] Therefore, solid organic fertilizer and liquid organic fertilizer each have their advantages, and the choice of which fertilizer depends on the specific planting needs and conditions. If you need to quickly supplement nutrients, especially during the critical growth period, liquid organic fertilizer is a better choice; if you need to improve soil structure and provide a lasting nutrient supply in the long term, solid organic fertilizer is more suitable. In actual planting, solid and liquid organic fertilizers can also be used in combination to achieve the best planting effect. The device of the present invention is mainly used for topdressing solid biological organic fertilizer.

[0067] Working process:

[0068] Move the device to the plot that needs fertilization, and at the same time transport the required biological organic fertilizer to the place for easy fertilization;
