Description

Technical Field

[0001] The present invention relates to the technical field of fertilizing equipment, and in particular to organic liquid fertilizer fertilizing equipment for protecting and utilizing black soil. Background Art

[0002] As a precious soil resource, black soil plays an irreplaceable and important role in ensuring national food security and maintaining sustainable agricultural development. With the acceleration of agricultural modernization, the protection and utilization of black soil has become one of the key tasks in the agricultural field. In agricultural production on black soil, reasonable fertilization is the key link to increase crop yields, improve soil quality, and achieve sustainable utilization of black soil. Organic liquid fertilizer, as a fertilizer rich in multiple nutrients and friendly to the soil environment, has been widely used in the protection and utilization of black soil.

[0003] At present, there are many kinds of equipment for applying organic liquid fertilizer on the market. These equipment have met the needs of agricultural production to a certain extent. However, the existing equipment for applying organic liquid fertilizer still has many defects in practical application, which limits its effect in the protection and utilization of black soil.

[0004] In terms of fertilization uniformity, most existing equipment uses a relatively simple spraying method, which makes it difficult to spray liquid fertilizer evenly on each crop. In large areas of farmland or areas with uneven crop planting density, it is easy to have excessive or insufficient fertilization in some areas, resulting in uneven crop growth quality and poor yield stability. This not only affects the economic benefits of crops, but is also not conducive to the balanced distribution and long-term utilization of soil nutrients in black soil.

[0005] Low fertilizer utilization rate is another prominent problem of existing fertilization equipment. Due to unreasonable spraying methods, liquid fertilizers are often sprayed in the form of larger droplets, falling quickly and staying in the air for a short time. Many fertilizers fall directly to the ground due to gravity and cannot be fully absorbed and utilized by crops. This not only causes fertilizer waste and increases farmers' fertilizer procurement costs, but also the excess fertilizer is lost in the soil, which may also pollute the surrounding water and soil and damage the ecological environment of the black soil.

[0006] Therefore, it is necessary to provide an organic liquid fertilizer fertilization equipment for black soil protection and utilization to solve the above technical problems. Summary of the Invention

[0017] The present invention provides an organic liquid fertilizer fertilizing device for protecting and utilizing black soil, which has the following beneficial effects:

[0018] (1) Expand the spraying range and improve the uniformity of fertilization

[0019] The air cylinder drives the pressure plate to squeeze the airbag, causing a high-speed airflow to be ejected from the exhaust pipe, which collides and mixes with the liquid fertilizer ejected from the discharge pipe, further breaking up the originally relatively concentrated liquid fertilizer droplets into smaller and more uniform droplets. Driven by the airflow, these fine droplets can diffuse to a wider area, significantly expanding the spraying range of the liquid fertilizer. In actual agricultural production, for large areas of farmland or areas with uneven crop planting density, it can ensure that every crop can obtain fertilizer nourishment evenly, avoiding the situation of excessive or insufficient local fertilization, thereby improving the growth quality of crops and yield stability.

[0020] Reduce fertilizer spillage and improve fertilizer utilization

[0021] Because liquid fertilizer is dispersed into smaller droplets, its falling speed is relatively slowed down and its residence time in the air is prolonged. This not only enables the fertilizer to come into contact with the air more fully, which is conducive to the uniform distribution of the fertilizer, but more importantly, it reduces the situation where liquid fertilizer is directly spilled onto the ground due to gravity. According to actual tests, compared with traditional fertilization methods, this device can reduce the amount of fertilizer spilled and effectively improve the utilization rate of fertilizer. For farmers, this means that with the same amount of fertilizer, better fertilization effects can be obtained and fertilizer procurement costs can be reduced. From an environmental protection perspective, it reduces the loss of fertilizer in the soil and reduces the risk of pollution to surrounding water bodies and soil.

[0022] Precisely control the spraying effect to meet diverse needs

[0023] The device can achieve precise control of the spraying effect by adjusting parameters such as the working pressure of the cylinder and the moving speed of the pressure plate according to different crop planting densities, fertilization requirements and environmental conditions. For example, for crops with vigorous growth and high fertilizer requirements, the working pressure of the cylinder can be appropriately increased to make the sprayed droplets finer and the spraying range wider; in an environment with strong winds, the moving speed of the pressure plate can be adjusted to change the airflow intensity to ensure that the fertilizer can be accurately sprayed to the target area. This flexibility enables the device to be widely used in various crop planting scenarios to meet the diverse needs of agricultural production.

[0024] 2. Beneficial effects of precise discharge control

[0025] Ensure stable discharge of fertilizer and achieve precise fertilization

[0026] The meshing transmission between the toothed plate and the gear drives the movable shaft and cam to rotate, thereby controlling the movement of the movable rod, the limit block, and the sealing block, achieving precise opening and closing of the drainage channel. This mechanical control method is stable and reliable, ensuring that the organic liquid fertilizer in the medicine box is discharged smoothly when needed, and the discharge volume can be precisely adjusted according to actual needs. In agricultural production, accurate fertilizer application control is crucial to crop growth. Excessive or insufficient fertilizer application can affect crop yield and quality. The device's precise drainage control function can effectively prevent this from happening, providing a guarantee for healthy crop growth.

[0027] Buffer protection device to extend service life

[0028] During the movement of the sealing block, the damping spring is compressed, which can provide a certain buffering effect and reduce the impact of impact force on the device. During long-term use, this buffering design can effectively reduce the risk of wear and damage between components and extend the service life of the device. For farmers, it reduces the cost of equipment maintenance and replacement and improves the use efficiency of the equipment.

[0029] 3. Beneficial effects of fertilizer recovery system

[0030] Realize fertilizer recycling and reduce fertilization costs

[0031] The spilled fertilizer will fall into the liquid receiving box, and the fertilizer will be extracted and transported back to the medicine box through the pump body, the first fixed pipe, the second fixed pipe and the second delivery pipe, thus realizing the recycling of fertilizer. It is estimated that the utilization rate of fertilizer can be improved through this recycling system, which greatly reduces the cost of fertilization. For large-scale agricultural production, this is a considerable economic benefit. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] Please refer to Figures 1-8 , an organic liquid fertilizer fertilizing equipment for protecting and utilizing black soil includes a frame 1, a medicine box 2 is provided on the top of the frame 1, a fertilizer assembly 3 is provided at the bottom of the medicine box 2, the fertilizer assembly 3 includes a discharge box 31 fixedly installed in a row at the bottom of the medicine box 2, and the discharge box 31 is connected to the medicine box 2, a first conveying pipe 34 is connected to the bottom of the discharge box 31, and the first conveying pipe 34 is installed on the frame 1 through a support frame 35, a liquid separation pipe 36 is connected to the bottom of the first conveying pipe 34, and the other end of the liquid separation pipe 36 is connected to a horizontal pipe 37, and a row of drain pipes 38 are connected to the bottom of the horizontal pipe 37, an air bag 311 is provided between the two horizontal pipes 37, and an air intake pipe 312 and an exhaust pipe 313 are respectively provided on both sides of the air bag 311, and the positions of the exhaust pipe 313 and the drain pipe 38 correspond to each other;

[0043] The frame 1 is fixedly connected to a mounting frame 11 on both sides at one end, and a drive shaft 12 is rotatably connected to the mounting frame 11. A swing frame 13 is fixedly connected to the mounting frame 11, and a moving wheel 14 is rotatably provided on the swing frame 13. The moving wheel 14 is transmission-connected to the drive shaft 12 through a first sprocket assembly 15, and one end of the rotating shaft 32 is transmission-connected to the rotating shaft 32 through a second sprocket assembly 16. A turning cone 17 is provided at the other end of the frame 1. When the frame 1 and the moving wheel 14 move, the moving wheel 14 drives the drive shaft 12 to rotate synchronously through the first sprocket assembly 15, and the drive shaft 12 drives the rotating shaft 32 to rotate synchronously through the second sprocket assembly 16. The rotating shaft 32 drives the liquid separator 33 to rotate, thereby enabling the transportation of organic liquid fertilizer, and the turning cone 17 turns the soil;

[0044] The bottom of the medicine box 2 is rotatably connected to a rotating shaft 32, and the rotating shaft 32 passes through the discharge box 31. The outer wall of the rotating shaft 32 is provided with a plurality of liquid separation plates 33 in a circumferential array, and the liquid separation plates 33 are installed in the discharge box 31. When the rotating shaft 32 rotates, the rotating shaft 32 can drive the liquid separation plates 33 located in the discharge box 31 to rotate, so that the rotating liquid separation plates 33 can intermittently transport the organic liquid fertilizer to the first delivery pipe 34 and the horizontal pipe 37, and discharge it through the discharge pipe 38;

[0045] Cylinders 39 are fixedly connected to both sides of the inner cavity of the support frame 35, and a pressure plate 310 is fixedly connected to the output end of the cylinder 39. The pressure plate 310 is connected to the top of the airbag 311. The airbag 311 is installed in the support frame 35, and a one-way valve is provided on the air inlet pipe 312 and the exhaust pipe 313. The one-way valve on the air inlet pipe 312 allows gas to enter the air inlet pipe 312 for reset, and the one-way valve on the exhaust pipe 313 allows gas to be discharged. By opening the cylinder 39, the pressure plate 310 is driven to move downward, so that the pressure plate 310 can squeeze the airbag 311 when moving downward, so that the gas in the airbag 311 is discharged through the exhaust pipe 313.

[0046] A toothed plate 314 is fixedly connected to the outer wall of the air intake pipe 312, and a movable shaft 315 is rotatably connected to the axis of the cross tube 37. One end of the movable shaft 315 is fixedly connected to a gear 316. The gear 316 meshes with the toothed plate 314. When the cylinder 39 drives the pressure plate 310 to move downward, the air bag 311 is compressed, thereby driving the air intake pipe 312 and the toothed plate 314 to move downward, so that the toothed plate 314 drives the meshed gear 316 and the movable shaft 315 to rotate. When the air bag 311 is driven to move upward for air inhalation, the air bag 311 can drive the air intake pipe 312 and the toothed plate 314 to move upward and reset, thereby driving the gear 316 and the movable shaft 315 to rotate in the opposite direction. In this way, the gear 316 and the movable shaft 315 can be driven to rotate forward and backward.

[0047] The outer wall of the movable shaft 315 is fixedly connected to a row of cams 318, and the inner wall of the cross tube 37 is fixedly connected to a fixed plate 317. A row of moving rods 319 are slidably connected to the fixed plate 317. The top of the moving rod 319 slides in contact with the side wall of the cam 318. The outer wall of the moving rod 319 is fixedly connected to a limit block 320. A damping spring 321 is provided between the limit block 320 and the fixed plate 317 and is sleeved on the moving rod 319. The bottom of the moving rod 319 is fixedly connected to a sealing block 322, and the sealing block 322 is sealingly slidably installed in the drain pipe 38. When the cam 318 rotates until the convex surface contacts the end of the moving rod 319, the cam 318 can push the moving rod 319, the limit block 320, and the sealing block 322 to move downward and compress the damping spring 321, so that the sealing block 322 moves out of the drain pipe 38, so that the sealing block 322 no longer seals and combs the drain pipe 38, thereby allowing the organic liquid fertilizer to be discharged through the drain pipe 38;

[0048] The support frame 35 is fixedly connected to a liquid receiving box 323 on both sides, and the position of the liquid receiving box 323 and the drain pipe 38 correspond to each other. The inner cavity of the liquid receiving box 323 is tilted inwardly so that the liquid can flow inwardly. A first fixed pipe 324 is connected to one side of the liquid receiving box 323, and the other end of the first fixed pipe 324 is connected to the second fixed pipe 325. The other end of the second fixed pipe 325 is connected to a pump body 326, and the other end of the pump body 326 is connected to a second delivery pipe 327. The other end of the second delivery pipe 327 is connected to the medicine box 2. During the fertilizer spraying process, some fertilizer will inevitably spill, and the spilled fertilizer can fall into the liquid receiving box 323. The pump body 326 cooperates with the second fixed pipe 325 and the first fixed pipe 324 to extract the fertilizer in the liquid receiving box 323 and deliver it to the medicine box 2 through the second delivery pipe 327. In this way, the spilled fertilizer can be recovered, which is convenient for reuse of the recovered fertilizer.

[0049] In the embodiment of the present invention, first, the control system sends an opening signal to the cylinder 39, and the cylinder 39 responds immediately, and the piston inside it begins to move downward under the action of air pressure. As the piston of the cylinder 39 moves downward, the pressure plate 310 connected thereto also begins to descend synchronously. In the process of moving downward, the pressure plate 310 gradually approaches the airbag 311 that cooperates with it. The airbag 311 is made of a special material with high strength and high elasticity, has good sealing and pressure resistance, and can withstand a certain pressure without breaking. When the pressure plate 310 contacts the airbag 311 and continues to apply pressure, the airbag 311 is squeezed, and the air inside it is squeezed. As the airbag 311 is further squeezed, the internal gas pressure continues to rise. When it reaches a certain level, the gas begins to look for a release channel. At this time, the exhaust pipe 313 connected to the airbag 311 plays a key role. The exhaust pipe 313 is made of high-quality metal material with a smooth inner wall, which can effectively reduce the resistance of gas flow. Under the action of high pressure, the gas flows rapidly along the exhaust pipe 313 and is finally ejected from the outlet of the exhaust pipe 313. The outlet position of the exhaust pipe 313 has been carefully designed, and its spray direction is precisely toward the drain pipe 38 to spray liquid. When the high-speed airflow is ejected from the exhaust pipe 313, it collides and mixes with the liquid fertilizer ejected from the drain pipe 38. The high-speed airflow exerts a strong impact and dispersion effect on the liquid fertilizer, so that the relatively concentrated liquid fertilizer droplets are further broken up to form smaller and more uniform droplets. These fine droplets can be spread to a wider area under the drive of the airflow, thereby significantly expanding the spraying range of the liquid fertilizer. At the same time, since the liquid fertilizer is dispersed into smaller droplets, its falling speed is relatively slowed down and the time it stays in the air is prolonged, which not only allows the fertilizer to be more fully in contact with the air, but also has the effect of It is conducive to the uniform distribution of fertilizers and can also reduce the situation where liquid fertilizers are directly spilled onto the ground due to gravity, effectively reducing fertilizer waste and improving fertilizer utilization. Through this pneumatic assisted spraying method, we have successfully achieved the expansion of the liquid fertilizer spraying range and the reduction of the spillage amount, bringing higher benefits and a more environmentally friendly fertilization method to agricultural production. In actual application, the device can achieve precise control of the spraying effect by adjusting parameters such as the working pressure of the cylinder 39 and the moving speed of the pressure plate 310 according to different crop planting densities, fertilization requirements and environmental conditions, thereby meeting the diverse needs of agricultural production.

[0050] When the tooth plate 314 moves downward, it meshes with the gear 316 for transmission. The gear 316 is installed on the movable shaft 315, and the movable shaft 315 is fixed to the bracket of the device through a bearing and can rotate freely. Driven by the tooth plate 314, the gear 316 starts to rotate clockwise, thereby driving the movable shaft 315 to rotate synchronously; the rotation of the movable shaft 315 further triggers the movement of the cam 318. The cam 318 and the movable shaft 315 are connected by a key to ensure that the two can rotate synchronously. The profile of the cam 318 has been carefully designed. The height difference and shape of the convex and concave surfaces can accurately control the movement stroke of the moving rod 319. When the cam 318 rotates until the convex surface contacts the end of the moving rod 319, the cam 318 applies an upward thrust to the moving rod 319; the moving rod 319 is made of high-strength, lightweight aluminum alloy material, and its surface is anodized and has good wear resistance and corrosion resistance. The moving rod 319 is fixedly connected to the limit block 320 The limit block 320 plays the role of limiting the moving range of the moving rod 319 to prevent it from excessive movement and damaging other parts. Under the thrust of the cam 318, the moving rod 319 drives the limit block 320 and the sealing block 322 connected thereto to move downward; the sealing block 322 is made of rubber material, and its shape matches the inner diameter of the drain pipe 38, which can fit tightly against the inner wall of the drain pipe 38 to achieve sealing of the drain pipe 38. During the movement, the damping spring 321 is compressed. The damping spring 321 is selected from a spring with appropriate stiffness and damping coefficient, which can provide a certain buffering effect during the movement of the sealing block 322, reducing the impact of the impact force on the device. As the sealing block 322 moves downward, it gradually moves out of the drain pipe 38, the channel of the drain pipe 38 is opened, and is no longer sealed by the sealing block 322. At this time, the organic liquid fertilizer in the medicine box 2 is smoothly discharged through the drain pipe 38 under the action of its own gravity and system pressure, thereby achieving accurate spraying of the fertilizer.

[0051] During the fertilizer spraying process, although the device is well designed, it is inevitable that some fertilizer will spill due to various reasons, resulting in uneven spraying. In order to achieve fertilizer recycling, the device is equipped with a special recovery system. The spilled fertilizer will fall into the liquid receiving box 323. The liquid receiving box 323 is made of stainless steel with good corrosion resistance and strength. Its shape and size are carefully designed to collect the spilled fertilizer to the greatest extent.

[0052] The liquid receiving box 323 is connected to the pump body 326 through the first fixed pipe 324. The first fixed pipe 324 is made of a plastic hose with a certain degree of flexibility, which can adapt to the position change of the liquid receiving box 323. The pump body 326 uses a high-efficiency, low-noise centrifugal pump, and its flow rate and head can meet the needs of fertilizer recovery. The pump body 326 is connected to the other end of the liquid receiving box 323 through the second fixed pipe 325 to form a closed circulation loop. When a certain amount of fertilizer has accumulated in the liquid receiving box 323, the operator starts the pump body 326, and the pump body 326 starts working, generating a strong suction force to pump the liquid receiving box 323 The fertilizer in the medicine box 2 is extracted through the first fixed pipe 324 and the second fixed pipe 325, and the extracted fertilizer is then transported to the medicine box 2 through the second delivery pipe 327. The second delivery pipe 327 adopts a corrosion-resistant plastic pipe, and its inner diameter and length are selected according to actual needs to ensure that the fertilizer can be smoothly transported back to the medicine box 2; through this fertilizer recovery system, the spilled fertilizer can be collected and transported back to the medicine box 2 in time, realizing the recycling of fertilizer, which not only reduces the cost of fertilization and reduces the waste of fertilizer, but also avoids the pollution of fertilizer to the environment, which meets the requirements of sustainable development of modern agriculture.

[0053] The working principle of the organic liquid fertilizer fertilization equipment for black soil protection and utilization provided by the present invention is as follows:

[0054] When the cylinder 39 drives the pressure plate 310 to move downward, the air bag 311 is compressed, thereby driving the air intake pipe 312 and the gear plate 314 to move downward, so that the gear plate 314 drives the meshing gear 316 and the movable shaft 315 to rotate;

[0055] The movable shaft 315 can drive the cam 318 to rotate synchronously when rotating. When the cam 318 rotates until the convex surface contacts the end of the movable rod 319, the cam 318 can push the movable rod 319, the limit block 320, and the sealing block 322 to move downward, and compress the damping spring 321, so that the sealing block 322 moves out of the drain pipe 38, so that the sealing block 322 no longer seals and combs the drain pipe 38, thereby allowing the organic liquid fertilizer to be discharged through the drain pipe 38;

[0056] During the fertilizer spraying process, some fertilizer will inevitably spill, and the spilled fertilizer can fall into the liquid receiving box 323. The pump body 326 cooperates with the second fixed pipe 325 and the first fixed pipe 324 to extract the fertilizer in the liquid receiving box 323 and transport it to the medicine box 2 through the second delivery pipe 327. In this way, the spilled fertilizer can be recovered, which is convenient for reuse of the recovered fertilizer.

[0057] Compared with the related art, the organic liquid fertilizer fertilization equipment for black soil protection and utilization provided by the present invention has the following beneficial effects:

[0058] 1. Expand the spraying range and improve the uniformity of fertilization

[0059] The cylinder 39 drives the pressure plate 310 to squeeze the airbag 311, causing the exhaust pipe 313 to spray out a high-speed airflow, which collides and mixes with the liquid fertilizer sprayed out of the discharge pipe 38, further breaking up the originally relatively concentrated liquid fertilizer droplets into smaller and more uniform droplets. Driven by the airflow, these fine droplets can diffuse to a wider area, significantly expanding the spraying range of the liquid fertilizer. In actual agricultural production, for large areas of farmland or areas with uneven crop planting density, it can ensure that every crop can obtain fertilizer nourishment evenly, avoiding the situation of excessive or insufficient fertilization in some areas, thereby improving the growth quality of crops and the stability of yield.

[0060] 2. Reduce fertilizer spillage and improve fertilizer utilization

[0061] Because liquid fertilizer is dispersed into smaller droplets, its falling speed is relatively slowed down and its residence time in the air is prolonged. This not only enables the fertilizer to come into contact with the air more fully, which is conducive to the uniform distribution of the fertilizer, but more importantly, it reduces the situation where liquid fertilizer is directly spilled onto the ground due to gravity. According to actual tests, compared with traditional fertilization methods, this device can reduce the amount of fertilizer spilled and effectively improve the utilization rate of fertilizer. For farmers, this means that with the same amount of fertilizer, better fertilization effects can be obtained and fertilizer procurement costs can be reduced. From an environmental protection perspective, it reduces the loss of fertilizer in the soil and reduces the risk of pollution to surrounding water bodies and soil.

[0062] 3. Precisely control the spraying effect to meet diverse needs

[0063] The device can achieve precise control of the spraying effect by adjusting parameters such as the working pressure of the cylinder 39 and the moving speed of the pressure plate 310 according to different crop planting densities, fertilization requirements and environmental conditions. For example, for crops with vigorous growth and high fertilizer requirements, the working pressure of the cylinder 39 can be appropriately increased to make the sprayed droplets finer and the spraying range wider; in an environment with strong winds, the moving speed of the pressure plate 310 can be adjusted to change the airflow intensity to ensure that the fertilizer can be accurately sprayed to the target area. This flexibility enables the device to be widely used in various crop planting scenarios to meet the diverse needs of agricultural production.

[0064] 2. Beneficial effects of precise discharge control

[0065] 1. Ensure stable discharge of fertilizer and achieve precise fertilization

[0066] The meshing transmission between the toothed plate 314 and the gear 316 drives the movable shaft 315 and the cam 318 to rotate, thereby controlling the movement of the movable rod 319, the stop block 320, and the sealing block 322, thereby precisely opening and closing the drainage pipe 38. This mechanical control method is stable and reliable, ensuring that the organic liquid fertilizer in the medicine box 2 is smoothly discharged when needed, and the discharge amount can be precisely adjusted according to actual needs. In agricultural production, accurate control of fertilizer application is crucial to crop growth. Excessive or insufficient fertilizer application can affect crop yield and quality. The precise drainage control function of this device can effectively prevent this from happening, providing a guarantee for the healthy growth of crops.
