Description

Technical Field

[0001] The invention belongs to the technical field of agricultural planting, and specifically relates to a mobile integrated water and fertilizer equipment. Background Art

[0002] The mobile integrated water and fertilizer equipment refers to a new agricultural technology that combines irrigation and fertilization. Integrated water and fertilizer is to mix solid or liquid fertilizers into fertilizer solutions according to the nutrient content of the soil and the fertilizer requirements of different crop varieties with the help of a pressure system (or natural terrain drop), and then irrigate the land with the fertilizer solutions. The mobile integrated water and fertilizer equipment is powered by a diesel water pump integrated machine, which can achieve precise irrigation and fertilization, improve the utilization rate of water and fertilizer. The mobile wheels designed at the bottom can move between different plots, which is very suitable for the needs of modern agriculture. Timely, effectively and scientifically meeting the water and fertilizer requirements of soybeans through the integrated water and fertilizer technology is the key measure to increase the yield of soybeans per unit area. The integrated water and fertilizer equipment is also widely used in scenarios such as field crops, greenhouse greenhouses, fruit tree planting and facility agriculture.

[0003] In the prior art, external water is usually pumped by a diesel water pump integrated machine and transmitted through a connecting pipeline. During this process, a part of the water in the connecting pipeline is diverted and flows into the fertilizer tank through a fertilization inlet pipe, where it is mixed with the fertilizer in the tank. The mixed fertilizer solution then flows back to the connecting pipeline through a fertilization outlet pipe, and then is filtered by a disc filter, and finally discharged through a drain pipe for irrigation. However, when it comes to the dissolution operation of solid granular fertilizers in the fertilizer tank, some solid granular fertilizers are relatively hard due to their own hardness. Once the hardness of the solid granular fertilizers is relatively large, it is extremely easy to form blockages inside the fertilization outlet pipe, seriously hindering the normal outflow of water containing fertilizers, resulting in a significant reduction in the fertilizer concentration of the water discharged from the drain pipe. At the same time, if the dissolution rate of solid granular fertilizers in the fertilizer tank continues to be slow, it will also continuously affect the fertilizer concentration of the water discharged from the drain pipe, causing crops to be unable to obtain sufficient and appropriately concentrated fertilizer solutions, greatly restricting the effectiveness of the integrated water and fertilizer equipment, and further affecting the growth trend and final yield of crops. Therefore, we propose a mobile integrated water and fertilizer equipment. Summary of the Invention

[0015] A grinding column is fixedly arranged at the bottom of the rotating column for grinding the granular impurities falling on the top of the chassis.

[0016] Preferably, a fixed pipe is fixedly arranged at the bottom of the material cylinder;

[0020] Preferably, a diesel water pump integrated machine, a sand settling tank, a centrifugal filter and a disc filter are respectively arranged on the flat trolley. A horizontal pipe is arranged at the bottom of the disc filter. A drain pipe is arranged at the end of the horizontal pipe. A water inlet pipe is arranged on the diesel water pump integrated machine.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] (1) Through the designed crushing mechanism of the present invention, three-level protrusions are arranged on the conical lower grinding disc, and a progressive crushing channel is formed in cooperation with the circular groove of the upper grinding disc. The granular fertilizer needs to pass through the gaps between the three-level protrusions in sequence, increasing the crushing time of the granular fertilizer, and thus enhancing the crushing effect on the granular fertilizer. In cooperation with the re-crushing of the incompletely crushed granular fertilizer between the upper grinding disc and the mesh ring, the conical plate and the conical seat in the feeding assembly can synchronize the rotation speed of the stirring frame and the upper grinding disc by adjusting the opening size, and the falling speed of the granular fertilizer in the first hopper is controlled by two methods, so as to control the amount of the crushed powdery fertilizer falling into the lower fertilizing tank, making the amount of the water containing fertilizer solution flowing out of the fertilizing tank remain consistent for a long time, and thus making the concentration of the water containing fertilizer solution discharged from the drain pipe consistent.

[0023] (2) Through the combination of the designed cleaning part and the stirring part, the cleaning part synchronously sweeps away impurities such as particles and dust attached to the outer wall and the upper surface through the cleaning brush, the first scraping strip, the second scraping strip and the middle scraping strip during the rotation of the upper gear, the toothed ring and the small gear, avoiding the probability of abrasion to the gear, the toothed ring and the small gear, and extending their service life. At the same time, the rotation of the upper gear on the stirring part indirectly drives the stirring frame located in the fertilizing tank to rotate, stirring and mixing the ground powdery fertilizer and water in the fertilizing tank, which can not only improve the mixing effect, but also prevent the precipitation of the fertilizer solution.

[0024] (3) The comminution mechanism of the present invention is composed of a barrel, a driving rod, a waterproof motor II, a mesh barrel, an upper box, an inclined filter plate, an installation pipe, a connecting rod, a stirring loop bar, a chopping blade, a grinding column, a chassis, a rotating column, and a fixed pipe. The solid granular fertilizer is divided into two parts by the inclined filter plate. The fine powder part: directly passes through the inclined filter plate and falls into the fertilizing tank to be quickly dissolved with water. The granular part: slides along the inclined filter plate into the conical opening at the bottom of the upper box, enters the mesh barrel through the installation pipe, avoiding the un-screened particles directly entering the tank to form precipitation. The chopping blade rotates at a high speed in the mesh barrel to chop the particles into powder, and the grinding column performs secondary grinding on the granular fertilizer at the bottom, further crushing the residual particle size. While the chopping blade driven by the rotating column and the grinding column crush the particles, they drive the water flow in the mesh barrel to form a vortex, playing a stirring effect and increasing the mixing uniformity.

Specific embodiments

[0040] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1

[0042] Please refer to Figures 1-10, the present invention provides a technical solution: a mobile integrated water and fertilizer equipment, including a flatbed trolley 100, a connecting pipe 104, a fertilizer tank 108, and a fertilizer inlet pipe 103 and a fertilizer outlet pipe 111 fixed on the fertilizer tank 108. Two sets of moving wheels are installed at the bottom of the flatbed trolley 100, and the right side is connected to a traction machine through a towing head. The flatbed trolley 100 is driven to move by the traction machine, which is convenient to move to different places for irrigation and fertilization. The fertilizer tank 108 utilizes the negative pressure (Bernoulli principle) generated when the water flow in the connecting pipe 104 passes through a Venturi tube (or throttling device). When the high-speed water flow passes through the narrow section of the Venturi tube, the flow rate increases and the pressure decreases, forming a vacuum suction force to suck the solution in the fertilizer tank 108 into the connecting pipe 104, or a pressure difference is formed between the connecting pipe 104 and the fertilizer tank 108 through a differential pressure valve to suck the solution in the fertilizer tank 108 into the connecting pipe 104. A crushing mechanism is provided on the fertilizer tank 108, and the crushing mechanism includes a grinding assembly. The grinding assembly includes an upper grinding disc 202, a conical lower grinding disc 214, and a pipe body 200 fixed on the fertilizer tank 108. The upper grinding disc 202 and the conical lower grinding disc 214 are both located inside the pipe body 200. A mesh ring 213 is fixedly arranged between the outer wall of the conical lower grinding disc 214 and the inner wall of the pipe body 200. During the rotation and grinding of the upper grinding disc 202, the bottom of the outer edge will also contact the mesh ring 213, which can grind the granular fertilizer that enters the mesh ring 213 and has not become powdery. Multiple groups of protrusions 215 are fixedly arranged on the upper surface of the conical lower grinding disc 214. The outside of the protrusions 215 can penetrate into the circular grooves in the upper grinding disc 202, and circular grooves for the protrusions 215 to penetrate are opened on the lower surface of the upper grinding disc 202;

[0043] A first hopper 201 is arranged above the upper grinding disc 202. A lower pipe 220 is fixedly arranged at the bottom of the first hopper 201. A second sealing bearing is arranged at the top of the upper grinding disc 202, and the bottom of the lower pipe 220 extends to the inner wall of the second sealing bearing;

[0044] A toothed ring 210 is sleeved and fixed on the outer side of the top of the lower pipe 220. An upper gear 209 is meshed with the outside of the toothed ring 210. A bracket 203 is fixedly arranged at the top of the fertilizer tank 108, and the pipe body 200 and the first hopper 201 are both fixed on the bracket 203;

[0045] A waterproof motor one 205 is fixedly arranged on the bracket 203. The working end of the waterproof motor one 205 is fixedly connected to the bottom of the upper gear 209.

[0046] Embodiment Two

[0047] On the basis of Embodiment One, please refer to Figures 7-9 , the crushing mechanism further includes a feeding assembly, which is arranged inside the lower pipe 220;

[0048] The feeding component includes a conical plate 217 located inside the lower pipe 220. The conical plate 217 is fixed on the upper rotating rod 211. A conical seat 219 is rotatably arranged inside the conical plate 217. A spiral column is connected to the inside of the conical plate 217 by threads. The working end of the spiral column contacts and presses against the conical seat 219. After adjusting the opening size between the conical seat 219 and the conical plate 217 by rotating the conical seat 219, the conical seat 219 can be fixed. The amount of granular fertilizer falling in the first hopper 201 can be adjusted according to the opened opening size. At the same time, the conical seat 219, the conical plate 217, the upper rotating rod 211, and the upper grinding disc 202 all rotate synchronously;

[0049] The inner wall of the upper grinding disc 202 is fixedly provided with an upper rotating rod 211. A seal bearing one 218 is arranged outside the upper rotating rod 211. The conical seat 219 is fixed on the outer wall of the seal bearing one 218. The top of the upper rotating rod 211 is fixedly provided with a stirring frame 212. When the granular fertilizer in the first hopper 201 is discharging, it is stirred in the first hopper 201 by the rotating stirring frame 212 to prevent the granular fertilizer from blocking the top position of the lower pipe 220 below.

[0050] Through the designed crushing mechanism of the present invention, three - level protrusions 215 are arranged on the conical lower grinding disc 214, and cooperate with the circular grooves of the upper grinding disc 202 to form a progressive crushing channel. The granular fertilizer needs to pass through the gaps between the three - level protrusions 215 in sequence, increasing the crushing time of the granular fertilizer, and thus increasing the crushing effect on the granular fertilizer. The incomplete - ly crushed granular fertilizer is crushed again between the upper grinding disc 202 and the mesh ring 213. The conical plate 217 and the conical seat 219 in the feeding component can be synchronized with the rotation speed of the stirring frame 212 and the upper grinding disc 202 by adjusting the opening size. The two methods control the falling speed of the granular fertilizer in the first hopper 201, and then control the amount of the crushed powdery fertilizer falling into the lower fertilizing tank 108, so that the amount of the fertilizer solution contained in the water flowing out of the fertilizing tank 108 remains consistent for a long time.

[0051] In summary, pour some solid granular fertilizers into the first hopper 201. At this time, start the waterproof motor 1 205 to drive the upper gear 209 above to rotate. The upper gear 209 drives the tooth ring 210 and the upper grinding disc 202 on the tooth ring 210 to rotate. The upper grinding disc 202 drives the upper rotating rod 211 to rotate, and then can drive the conical plate 217, the outer ring of the sealed bearing 1 218 and the conical seat 219 to rotate inside the lower pipe 220. At this time, some granular fertilizers in the first hopper 201 fall from the opening between the conical seat 219 and the conical plate 217, and then fall onto the lower conical grinding disc 214 below. The granular fertilizers are ground by the rotating upper grinding disc 202. At the same time, the granular raw materials falling onto the conical lower grinding disc 214 will first accumulate at the first-stage multi-group protrusions 215 near the center of the conical lower grinding disc 214, and then enter the middle second-stage protrusions 215 through the channels formed between the two groups of first-stage protrusions 215 under the rotation and rolling drive of the upper grinding disc 202. According to this principle, until it enters the third-stage protrusions 215 located away from the center of the conical lower grinding disc 214. Finally, with the rotation of the upper grinding disc 202 and the drive of the mucus, it enters the mesh ring 213 through the channels formed between the two groups of protrusions 215 at the third stage. At this time, some fertilizers ground into powder fall into the lower fertilizer application tank 108 through the mesh holes in the mesh ring 213. While the granular fertilizers falling onto the conical lower grinding disc 214 are ground and rolled by the first-stage, second-stage and third-stage protrusions 215 in turn, the speed of the granular fertilizers passing through the conical lower grinding disc 214 is slowed down, and the rolling and crushing effect on the granular fertilizers is increased. By controlling the rotation speed of the working end of the waterproof motor 1 205, the rotation speeds of the conical plate 217, the conical seat 219, the upper rotating rod 211 and the stirring frame 212 can be controlled. As the rotation speed of the stirring frame 212 is adjusted, the granular fertilizers in the first hopper 201 are quickly stirred. When the rotation speed of the stirring frame 212 is fast, the flow rate of the granular fertilizers in the first hopper 201 increases (breaking the adhesion between granular materials and promoting the feeding speed), which can increase the amount of granular fertilizers in the first hopper 201 entering the upper grinding disc 202. When the rotation speed slows down, the flow rate of the granular fertilizers in the first hopper 201 slows down (the granular fertilizers slow down the feeding speed due to adhesion or friction), reducing the amount of granular fertilizers in the first hopper 201 entering the upper grinding disc 202. Furthermore, the amount of granular fertilizers in the first hopper 201 entering the conical lower grinding disc 214 is controlled, so as to control the amount of fertilizers ground into powder entering the fertilizer application tank 108. The rotation speed can be controlled according to the amount of water flowing into the fertilizer application tank 108 or flowing out of the fertilizer application tank 108, so that the amount of fertilizer solution in the water flowing out of the fertilizer application tank 108 remains consistent for a long time;

[0052] Then start the integrated water and fertilizer machine. At this time, the diesel water pump integrated machine 101 on the integrated water and fertilizer machine starts, driving the external water source to enter the centrifugal filter 102 through the water inlet pipe 110. Sand and sediment are filtered in the centrifugal filter 102 (the centrifugal force generated by the high-speed rotating water flow separates sand grains and other heavier impurities from the water body), and the sediment sinks into the sedimentation tank 109 below. At this time, the water filtered by the centrifugal filter 102 enters the connecting pipe 104. During this period, a part of the water in the connecting pipe 104 is diverted and flows into the fertilizer tank 108 through the fertilizer inlet pipe 103, mixing with the powdered fertilizer that has fallen into the fertilizer tank 108 to form a fertilizer solution. Then, the fertilizer solution flows back into the connecting pipe 104 through the fertilizer outlet pipe 111 and mixes with the water in the connecting pipe 104. Finally, the water containing the fertilizer solution is discharged outward through the drain pipe 106 to irrigate and fertilize the crops on the planting ground.

[0053] Embodiment Three

[0054] Based on Embodiment Two, please refer to Figures 1-6 , a cleaning member is provided on the bracket 203. The cleaning member includes a cleaning brush 301 fixed on the bracket 203. The outer side of the cleaning brush 301 is in contact with the outer walls of the tooth ring 210 and the upper gear 209. Scraping strips one 300 and two 302 are respectively fixed at both ends of the cleaning brush 301. The scraping strip two 302 is used to scrape off the particulate impurities adhering to the upper surface of the upper gear 209, and the scraping strip one 300 is used to remove the particulate impurities adhering to the top of the tooth ring 210. A middle scraping strip is fixed on the cleaning brush 301, and the bottom of the middle scraping strip can be in contact with the upper surface of the pinion 305;

[0055] A stirring member is provided on the bracket 203. The stirring member includes a pinion 305 externally meshed with the tooth ring 210. A transfer rod 304 is fixed at the bottom of the pinion 305. The bottom of the transfer rod 304 extends into the interior of the fertilizer tank 108, and a stirring frame 306 is fixed at the bottom of the transfer rod 304;

[0056] A mechanical seal two 303 is provided on the fertilizer tank 108. The mechanical seal two 303 can increase the sealing performance between the transfer rod 304 and the fertilizer tank 108, and the bottom of the transfer rod 304 passes through the interior of the mechanical seal two 303.

[0057] In the present invention, the designed cleaning member and stirring member are combined. The cleaning member, through the cleaning brush 301, the first scraping strip 300, the second scraping strip 302 and the middle scraping strip, synchronously sweeps away impurities such as particles and dust adhering to the outer wall and the upper surface during the rotation of the upper gear 209, the gear ring 210 and the pinion gear 305, avoiding the probability of abrasion on the upper gear 209, the gear ring 210 and the pinion gear 305, and extending their service life. At the same time, the rotation of the upper gear 209 on the stirring member indirectly drives the stirring frame 306 located in the fertilizer application tank 108 to rotate, stirring and mixing the ground powdery fertilizer and water in the fertilizer application tank 108, which can not only increase the mixing effect but also prevent the fertilizer solution from precipitating.

[0058] In summary, during the rotation of the gear ring 210 and the upper gear 209, it is easy for some particles and dust to adhere to their surfaces. When they mesh, abrasion will occur, and at this time, they need to be cleaned. During cleaning, since the upper gear 209 rotates clockwise and the gear ring 210 rotates counterclockwise, the rotating upper gear 209 and gear ring 210 enter the cleaning brush 301, and the cleaning brush 301 sweeps away the dust particles adhering to their outer walls, reducing the probability of abrasion. At the same time, the cleaning brush 301 can also sweep away the particles and dust adhering to the outer wall of the pinion gear 305. Moreover, the second scraping strip 302 can remove some particle impurities adhering to the upper surface of the upper gear 209, the first scraping strip 300 can scrape off the particle impurities adhering to the upper surface of the gear ring 210, and at the same time, the middle scraping strip can also scrape off the particle impurities adhering to the upper surface of the pinion gear 305;

[0059] When the gear ring 210 rotates to drive the upper grinding disc 202 to grind the granular fertilizer, it will also drive the meshing pinion gear 305 to rotate. The pinion gear 305 drives the fixed transfer rod 304 below to rotate, and then drives the stirring frame 306 at the bottom to rotate. At this time, the stirring frame 306 stirs and mixes the powdery fertilizer and water falling into the fertilizer application tank 108, increasing the mixing effect.

[0060] In this embodiment, a diesel water pump integrated machine 101, a sand settling tank 109, a centrifugal filter 102 and a disc filter 105 are respectively arranged on the flat trolley 100. A pipeline is arranged at the bottom of the disc filter 105, a sewage pipe 107 is arranged at the bottom of the pipeline, and a drain pipe 106 is arranged at the end of the pipeline. An inlet water pipe 110 is arranged on the diesel water pump integrated machine 101, and an external water source pipe is connected to the inlet water pipe 110. Relying on the extraction of the diesel water pump integrated machine 101 and transmitted through the connecting pipeline 104. During this process, a part of the water is separated from the connecting pipeline 104 and flows into the fertilizer application tank 108 through the fertilizer inlet pipe 103, mixes with the fertilizer in the tank, and the mixed fertilizer solution then flows back into the connecting pipeline 104 from the fertilizer outlet pipe 111. Subsequently, the water containing the fertilizer solution is filtered by the disc filter 105 and finally discharged through the drain pipe 106 for irrigation.

[0068] The crushing mechanism of the present invention is composed of a barrel 400, a driving rod 401, a waterproof motor II 402, a mesh barrel 403, an upper box 404, an inclined filter plate 405, an installation pipe 406, a connecting rod 407, a stirring loop bar 408, a chopping blade 409, a grinding column 410, a chassis 411, a rotating column 412, and a fixing pipe 413. The solid granular fertilizer is divided into two parts by the inclined filter plate 405. The fine powder part: directly passes through the inclined filter plate 405 and falls into the fertilizing tank 108 to be quickly dissolved with water. The granular part: slides along the inclined filter plate 405 into the conical opening at the bottom of the upper box 404, enters the mesh barrel 403 through the installation pipe 406, avoiding the direct entry of un-screened particles into the tank to form precipitation. The chopping blade 409 rotates at a high speed in the mesh barrel 403 to chop the particles into powder form. The grinding column 410 performs secondary grinding on the granular fertilizer at the bottom, further crushing the particle size of the remaining particles. While the chopping blade 409 driven by the rotating column 412 and the grinding column 410 crush the particles, they drive the water flow in the mesh barrel 403 to form a vortex, playing a stirring effect and increasing the mixing uniformity. Under the double crushing of the chopping blade 409 and the grinding column 410, it is ensured that some particles with higher hardness can also be fully crushed, fundamentally solving the problems of slow dissolution and blockage of the fertilizing water outlet pipe 111 caused by particle residues.

[0069] In summary, first, turn on the diesel water pump integrated machine 101 according to the same principle as in the first embodiment above. Then, water enters the connecting pipe 104. During this period, a part of the water in the connecting pipe 104 is diverted and flows into the fertilizer application tank 108 through the fertilizer application water inlet pipe 103. Turn on the waterproof motor two 402. At this time, the working end of the waterproof motor two 402 drives the driving rod 401 to rotate, driving the rotating column 412 to rotate. The rotating column 412 drives a plurality of groups of chopping blades 409, grinding columns 410 and connecting rods 407 to rotate synchronously. The connecting rod 407 drives the stirring return strip 408 at the top to rotate (the stirring return strip 408 can stir the granular fertilizer that enters the bottom conical opening of the upper box 404 later to prevent blockage in the conical opening). Pour the solid granular fertilizer into the material cylinder 400. Then, open the valve on the fixed pipe 413 to an appropriate size. Then, the granular fertilizer falls along the fixed pipe 413 onto the inclined filter plate 405 in the upper box 404. At this time, some powdered fertilizers directly fall into the fertilizer application tank 108 below through the mesh holes in the inclined filter plate 405. The remaining granular fertilizers slide to the bottom position of the upper box 404 under the influence of the inclined surface of the inclined filter plate 405, and then fall into the mesh cylinder 403 through the conical opening at the bottom of the upper box 404 and the installation pipe 406. Since the water level line in the fertilizer application tank 108 is at a position above the middle of the mesh cylinder 403, the rotating chopping blades 409 chop the granular fertilizer into powder and dissolve it in the water at the same time, flowing out of the mesh cylinder 403 to the outside of the mesh cylinder 403. Some granular fertilizers sink to the bottom plate 411, and then the rotating grinding column 410 grinds the granular fertilizer on the bottom plate 411 into powder (the rotating chopping blades 409 and grinding columns 410 can also play a stirring role to increase the mixing effect of the powdered fertilizer and water). Then, it dissolves and mixes with the water and flows out to the outside of the mesh cylinder 403. The water and the powdered fertilizer in the fertilizer application tank 108 are mixed into a fertilizer solution, and then flow back into the connecting pipe 104 through the fertilizer application outlet pipe 111 and mix with the water in the connecting pipe 104. Finally, the water containing the fertilizer solution is discharged outward through the drain pipe 106 to irrigate and fertilize the crops on the planting land.
