Description

Technical Field

[0001] This invention relates to the field of saline-alkali land management technology, specifically to an apparatus and method for saline-alkali land management. Background Technology

[0002] Soil microorganisms can transform nutrients in saline-alkali soil from unavailable or slow-release forms into available or readily available forms. They can also accelerate nutrient humification, secrete phytase, and degrade most of the phytates in the soil, thereby improving saline-alkali soil conditions. Currently, microbial fertilizers are mainly produced by granulation machines and then evenly distributed in fields via mechanical spreading. Various spreading methods exist, such as drones and single-person backpack sprayers, with the single-person backpack sprayer being the most widely used due to its low cost.

[0003] However, traditional spraying buckets are mainly used for crystalline granular fertilizers; while granular microbial agents are mainly made of powdered matrix, which easily generates fine debris during production and transportation. In order to ensure the survival rate of beneficial bacteria, granular microbial agents are often applied in the early morning when there is dew, which can cause debris to stick to the spray nozzle of the spraying bucket under the action of dew, resulting in blockage of the spraying area. This leads to uneven spraying of the granular microbial agent and affects the effect of improving saline-alkali soil.

[0004] Based on this, the present invention designs an apparatus and method for the treatment of saline-alkali land to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide an apparatus and method for treating saline-alkali land, so as to solve the problems mentioned in the background art.

The output shaft of the motor is fixedly connected to a first pulley, and the first pulley is connected to a second pulley via a belt ring. The second pulley is fixedly connected to the outer wall of the rotating tube.

[0008] As a further embodiment of the present invention, the adjustable transmission mechanism includes an active push plate and a driven push plate. The active push plate is fixedly connected to the inner wall of the rotating tube, and the driven push plate is fixedly connected to the outer wall of the limiting chassis. One side of the active push plate can contact one side of the driven push plate. The adjustable transmission mechanism also includes an adjustment component for adjusting the up-and-down sliding of the rotating shaft.

[0009] As a further embodiment of the present invention, the adjusting component includes a toggle lever, the middle of which is rotatably connected to the lower side of the fan-shaped discharge bin, one end of which is fixedly connected to a first inclined block, the first inclined block being located on the lower side of the limiting chassis, the inclined surface of the first inclined block being able to contact the lower end of the rotating shaft, and a limiting locking unit being provided between the end of the toggle lever away from the first inclined block and the material barrel.

[0010] As a further embodiment of the present invention, the limiting locking unit includes two slots and an arc-shaped limiting frame. The two slots are respectively opened on the front and rear sides of the end of the actuating rod away from the first inclined block. A pressure plate is slidably connected to the inner side of each slot in the front-rear direction. An elastic telescopic rod is fixedly connected between the pressure plate and the slot. The arc-shaped limiting frame is sleeved on the outside of the actuating rod and is fixedly connected to the material barrel.

[0015] A method of using an apparatus for saline-alkali land treatment, the method comprising the following steps:

[0016] Step 1: Pour a sufficient amount of granular microbial agent into the feed tank;

[0017] Step 2: Drive the rotating pipe and rotating plate to rotate through the drive mechanism. The granular microbial agent falls into the fan-shaped discharge bin through the discharge pipe and is then swept by the rotating plate, so that it is sprayed out from the outlet of the fan-shaped discharge bin in a fan shape.

[0018] Step 3: Simultaneously with starting the drive mechanism, start the adjustable transmission mechanism. The rotating tube drives the rotating shaft and the conveying spiral disc to rotate through the adjustable transmission mechanism. The rotating shaft drives the screening funnel to vibrate up and down at a small amplitude and high frequency through the vibration mechanism. The debris in the granular inoculant falls sequentially through the sieve holes of the screening funnel and the slope of the closed funnel to the upper port of the rotating tube. The rotating conveying spiral disc transports the debris to the lower port of the rotating tube and discharges it.

[0019] Step 4: After all the debris in the granular microbial agent in the material tank has been completely screened and discharged, turn off the adjustable transmission mechanism;

[0020] Step 5: After the granular microbial agent in the material tank has been sprayed out, pour in a sufficient amount of granular microbial agent again to facilitate the continued spraying of the granular microbial agent.

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

[0022] This invention enables a drive mechanism to rotate a rotating tube and a rotating plate. The rotating plate sweeps granular microbial agent out of the fan-shaped discharge bin in a fan shape. The rotating tube drives a rotating shaft and a conveying spiral disc to rotate via an adjustable transmission mechanism. The rotating shaft drives a screening funnel to vibrate via a vibration mechanism. The vibration of the screening funnel causes debris in the microbial agent to settle to the bottom. The settled debris passes through the sieve holes of the screening funnel and the slope of the closed funnel, concentrating at the upper end of the rotating tube. The rotating conveying spiral disc transports the debris to the lower end of the rotating tube and squeezes it out through the gap between the rotating tube and the limiting base plate. This achieves the separation of granular microbial agent from debris, thus preventing debris from sticking and blocking part of the outlet of the fan-shaped discharge bin due to dew, ensuring that the granular microbial agent can be sprayed evenly from the outlet of the fan-shaped discharge bin.

[0023] This invention enables the screening and extrusion functions of granular microbial agents to be turned on or off at any time via an adjustable transmission mechanism. This allows users to choose to turn off the screening and extrusion functions according to real-time conditions, thereby reducing the energy consumption of the device. The adjustable transmission mechanism is easy to operate by simply moving the lever back and forth. The end of the lever is automatically fixed in the open or closed position by the limit locking unit without external force impact, thus ensuring the stability of the screening and extrusion functions and preventing the screening and extrusion functions from stopping or suddenly starting midway.

[0037] Please see Figure 1-11This invention provides a technical solution: a device for saline-alkali land treatment, comprising a material bucket 1, a closed funnel 2 fixedly connected to the lower inner side of the material bucket 1, a discharge pipe 3 fixedly connected to the middle of the closed funnel 2, a screening funnel 4 slidably connected to the upper outer wall of the discharge pipe 3 in the vertical direction, the screening funnel 4 being slidably connected to the inner wall of the material bucket 1 in the vertical direction, a fan-shaped discharge bin 5 fixedly connected to the lower end of the discharge pipe 3, a rotating pipe 6 rotatably connected inside the fan-shaped discharge bin 5, a plurality of rotating plates 7 arranged in a circular array fixedly connected to the outer wall of the rotating pipe 6 inside the fan-shaped discharge bin 5, a driving mechanism provided at the lower end of the rotating pipe 6 extending to the lower side of the fan-shaped discharge bin 5 and between it and the closed funnel 2, the driving mechanism being able to drive the rotating pipe 6 to rotate, and the lower end of the rotating pipe 6 extending to the fan-shaped... The upper side of the discharge hopper 5 is connected to the lower port of the closed funnel 2. The lower port of the rotating pipe 6 is rotatably connected to the limiting base 8 below the fan-shaped discharge hopper 5. The limiting base 8 is fixedly connected to the bottom wall of the fan-shaped discharge hopper 5. A rotating shaft 9 is provided in the middle of the rotating pipe 6. The lower end of the rotating shaft 9 is rotatably connected to the limiting base 8. The lower end of the rotating shaft 9 extends to the bottom of the limiting base 8 and is slidably connected to the limiting base 8 in the vertical direction. A conveying spiral disk 10 is fixedly connected to the upper half of the outer wall of the rotating shaft 9 inside the rotating pipe 6. An adjustable transmission mechanism is provided between the rotating pipe 6 and the rotating shaft 9. The rotating pipe 6 can drive the rotating shaft 9 to rotate through the adjustable transmission mechanism. A vibration mechanism is provided between the rotating shaft 9 and the screening funnel 4. The rotating shaft 9 can drive the screening funnel 4 to rotate up and down through the vibration mechanism.

[0038] When the above scheme is put into actual use, first pour a sufficient amount of granular microbial agent into the material bucket 1, and start the drive mechanism. The drive mechanism drives the rotating tube 6 to rotate, and the rotating tube 6 drives the rotating plate 7 to rotate. At this time, the granular microbial agent on the upper side of the screening funnel 4 in the material bucket 1 falls into the fan-shaped discharge bin 5 through the discharge pipe 3, and is swept out of the front outlet of the fan-shaped discharge bin 5 by the rotating plate 7. At the same time, start the adjustable transmission mechanism. The rotating tube 6 drives the rotating shaft 9 to rotate through the adjustable transmission mechanism, and moves the rotating shaft 9 up a certain distance. The rotating shaft 9 drives the conveying spiral disk 10 to rotate. After moving up, the rotating shaft 9 drives the screening funnel 4 to vibrate up and down at a small amplitude and high frequency through the vibration mechanism. In this way, the debris in the microbial agent in the screening funnel 4 sinks to the bottom through the vibration and falls into the closed funnel 2 through the sieve holes of the screening funnel 4. It then slides to the upper port of the rotating tube 6 through the slope of the closed funnel 2, and is then conveyed to the lower port of the rotating tube 6 by the rotating conveying spiral disk 10. Finally, it passes through the screen. The granular agent is squeezed out through the gap between the rotating tube 6 and the limiting base plate 8. In this way, the device can drive the rotating tube 6 and the rotating plate 7 to rotate through the drive mechanism. The rotating plate 7 sweeps the granular agent out of the outlet of the fan-shaped discharge bin 5 in a fan shape. The rotating tube 6 can drive the rotating shaft 9 and the conveying spiral disk 10 to rotate through the adjustable transmission mechanism. The rotating shaft 9 can drive the screening funnel 4 to vibrate through the vibration mechanism. The vibration of the screening funnel 4 can cause the debris in the agent to settle to the bottom. The settled debris is concentrated at the upper end of the rotating tube 6 through the sieve holes of the screening funnel 4 and the slope of the closed funnel 2. The rotating conveying spiral disk 10 conveys the debris to the lower end of the rotating tube 6 and squeezes it out through the gap between the rotating tube 6 and the limiting base plate 8. This achieves the separation of the granular agent and the debris, thereby avoiding the debris from sticking and blocking part of the outlet end of the fan-shaped discharge bin 5 due to dew. This ensures that the granular agent can be sprayed evenly from the outlet end of the fan-shaped discharge bin 5.

[0039] As a further embodiment of the present invention, the driving mechanism includes a motor 11, which is fixedly connected to the lower side of the closed funnel 2. The output shaft of the motor 11 is fixedly connected to a first pulley 12, and the first pulley 12 is connected to a second pulley 14 via a belt ring 13. The second pulley 14 is fixedly connected to the outer wall of the rotating tube 6.

[0040] When the above solution is put into actual use, the motor 11 is started, the motor 11 drives the first pulley 12 to rotate, the first pulley 12 drives the second pulley 14 to rotate through the belt ring 13, the second pulley 14 drives the rotating tube 6 to rotate, the rotating tube 6 drives the rotating plate 7 to rotate, so that the rotating plate 7 can sweep the granular bacterial agent out from the outlet end of the fan-shaped discharge bin 5; through the fixed setting of the motor 11 and the closed funnel 2, the vibration of the motor 11 can drive the closed funnel 2 to vibrate to a certain extent, so that the debris falling into the closed funnel 2 can slide to the upper port of the rotating tube 6.

[0041] As a further embodiment of the present invention, the adjustable transmission mechanism includes an active push plate 15 and a driven push plate 16. The active push plate 15 is fixedly connected to the inner wall of the rotating tube 6, and the driven push plate 16 is fixedly connected to the outer wall of the limiting chassis 8. One side of the active push plate 15 can contact one side of the driven push plate 16. The adjustable transmission mechanism also includes an adjustment component for adjusting the up-and-down sliding of the rotating shaft 9.

[0042] When the above scheme is put into actual use, the initial positions of the active push plate 15 and the driven push plate 16 are staggered vertically. When the rotating tube 6 rotates, the rotating tube 6 drives the active push plate 15 to rotate, while the driven push plate 16 does not rotate. At this time, the rotating shaft 9 is pushed upward by the adjusting component. The rotating shaft 9 drives the driven push plate 16 to move upward until it contacts the active push plate 15. The active push plate 15 drives the driven push plate 16 to drive the rotating shaft 9 to rotate. The rotating shaft 9 drives the conveying spiral disk 10 to rotate, thereby squeezing out the debris in the granular bacterial agent.

[0043] As a further embodiment of the present invention, the adjusting assembly includes a toggle lever 17, the middle part of which is rotatably connected to the lower side of the fan-shaped discharge bin 5, and one end of the toggle lever 17 is fixedly connected to a first inclined block 18, which is located on the lower side of the limiting chassis 8. The inclined surface of the first inclined block 18 can contact the lower end of the rotating shaft 9, and a limiting locking unit is provided between the end of the toggle lever 17 away from the first inclined block 18 and the material barrel 1.

[0044] When the above scheme is put into actual use, the end of the lever 17 away from the first inclined block 18 is pushed backward. The first inclined block 18 is flipped forward under the push of the lever 17. The inclined surface of the first inclined block 18 pushes the rotating shaft 9 upward, thereby causing the driven push plate 16 to move upward to contact the active push plate 15, and then the rotating tube 6 drives the rotating shaft 9 to rotate. After the debris in the granular bacterial agent is completely separated and discharged, the same principle is applied in reverse, so that the first inclined block 18 is flipped backward and away from the lower end of the rotating shaft 9. The rotating shaft 9 slides freely to the reset under the action of gravity, thereby causing the driven push plate 16 to descend to be misaligned with the active push plate 15, and then the rotating shaft 9 stops rotating.

[0045] As a further embodiment of the present invention, the limiting locking unit includes two slots 19 and an arc-shaped limiting frame 22. The two slots 19 are respectively opened on the front and rear sides of the end of the actuating rod 17 away from the first inclined block 18. Pressure plates 20 are slidably connected to the inner side of each slot 19 in the front-rear direction. Elastic telescopic rods 21 are fixedly connected between the pressure plates 20 and the slots 19. The arc-shaped limiting frame 22 is sleeved on the outer side of the actuating rod 17 and is fixedly connected to the material bucket 1. The upper sidewall has a first lock hole 23 and a second lock hole 24 at its front and rear ends, respectively. The inner side of the slot 19 is slidably connected to a second inclined block 25 in the vertical direction. The lower end of the second inclined block 25 is fixedly connected to the inner wall of the slot 19 with a first spring 26. The inclined surface of the second inclined block 25 can contact the pressure plate 20 on the same side. The upper end of the second inclined block 25 can extend to the top of the lever 17. The second inclined blocks 25 on the front and rear sides can be inserted into the first lock hole 23 and the second lock hole 24, respectively.

[0046] When the above solution is put into actual use, when the end of the lever 17 away from the first inclined block 18 is moved backward, the finger will press the front pressure plate 20. The front pressure plate 20, through the inclined surface of the second inclined block 25, squeezes the second inclined block 25 into the recess 19, thereby separating the second inclined block 25 from the first lock hole 23. This causes the lever 17 to slide relative to the arc-shaped limiting frame 22. When the lever 17 is pushed to the rear end of the arc-shaped limiting frame 22, the first inclined block 18 has already pushed the rotating shaft 9 up to the set height. At the same time, the rear second... Under the elastic force of the first spring 26, the inclined block 25 moves upward until it is inserted into the second lock hole 24, thereby fixing the actuating rod 17 relative to the arc-shaped limiting frame 22, and thus keeping the rotating shaft 9 at the set height. When the end of the actuating rod 17 away from the first inclined block 18 is moved forward, the finger will press the pressure plate 20 on the rear side. The pressure plate 20 on the rear side squeezes the second inclined block 25 into the slot 19 through the inclined surface of the second inclined block 25, thereby separating the second inclined block 25 from the second lock hole 24, and thus making the actuating rod 17 and the arc-shaped limiting frame 22... When the lever 17 is pushed to the front end of the arc-shaped limiting frame 22, the inclined surface of the first inclined block 18 is completely away from the lower end of the rotating shaft 9, causing the rotating shaft 9 to reset under the action of gravity. At the same time, the second inclined block 25 on the front side moves upward under the elastic force of the first spring 26 until it is inserted into the first locking hole 23, thereby fixing the lever 17 relative to the arc-shaped limiting frame 22, thus keeping the rotating shaft 9 in the reset state. When the hand leaves the pressure plate 20, the pressure plate 20 will automatically reset under the elastic force of the elastic telescopic rod 21. This device can be adjusted by the transmission mechanism. The device can be turned on or off at any time to allow users to choose to turn off the screening and extrusion functions of the granular bacterial agent according to the real-time situation, thereby reducing the energy consumption of the device. The adjustable transmission mechanism is easy to operate by simply moving the lever 17 back and forth. The end of the lever 17 can be automatically fixed in the open or closed position under the action of the limit locking unit without external force collision, thus ensuring the stability of the screening and extrusion functions and preventing the screening and extrusion functions from stopping or suddenly starting midway.

[0047] As a further embodiment of the present invention, the vibration mechanism includes a fixed rod 27 and a fixed sleeve 28. The fixed rod 27 is fixedly connected to the upper end of the outer wall of the rotating shaft 9. The fixed sleeve 28 is fixedly connected to the bottom of the screening funnel 4 and is located above the fixed rod 27. The fixed sleeve 28 is concentrically arranged with the rotating shaft 9. The lower end of the fixed sleeve 28 is configured with a wavy structure, which can contact the fixed rod 27.

[0048] When the above scheme is put into actual use, when the rotating shaft 9 moves up to the set height under the action of the adjustable transmission mechanism, the fixed rod 27 moves up with the rotating shaft 9 to contact the wave-shaped structure at the lower end of the fixed sleeve 28. When the rotating shaft 9 drives the fixed rod 27 to rotate, the rotating fixed rod 27 drives the screening funnel 4 to vibrate up and down in a small amplitude at high frequency through the wave-shaped structure, so that the debris in the granular bacterial agent in the material bucket 1 settles to the bottom and falls into the closed funnel 2 through the sieve holes of the screening funnel 4.

[0049] As a further embodiment of the present invention, a lifting plate 29 is fixedly connected to the upper end of the rotating shaft 9. The lifting plate 29 is slidably connected to the inner wall of the fixed sleeve 28 in the vertical direction. A second spring 30 is fixedly connected between the lifting plate 29 and the screening funnel 4. During operation, the lifting plate 29 prevents the rotating shaft 9 from swaying during rotation, thus improving the stability of the rotating shaft 9 during rotation and vertical sliding. The second spring 30 facilitates the smoother reset of the rotating shaft 9, preventing it from getting stuck in the rotating tube 6 due to friction.

[0050] As a further embodiment of the present invention, pull rings 31 are fixedly connected to both the left and right sides of the upper port of the material bucket 1; during operation, the pull rings 31 are provided to facilitate the installation of a shoulder strap on the material bucket 1, so that the user can carry the material bucket 1 to his chest using the shoulder strap.

[0051] As a further embodiment of the present invention, an arc-shaped soft pad 32 is fixedly connected to the rear side of the material bucket 1; during operation, the arc-shaped soft pad 32 allows the user to more comfortably carry the material bucket 1 on their chest.

[0053] Step 1: Pour a sufficient amount of granular microbial agent into container 1;

[0054] Step 2: Drive the rotating pipe 6 and rotating plate 7 to rotate through the drive mechanism. The granular microbial agent falls into the fan-shaped discharge bin 5 through the discharge pipe 3 and is then swept by the rotating plate 7, so that it is sprayed out from the outlet of the fan-shaped discharge bin 5 in a fan shape.

[0055] Step 3: At the same time as starting the drive mechanism, start the adjustable transmission mechanism. The rotating tube 6 drives the rotating shaft 9 and the conveying spiral disk 10 to rotate through the adjustable transmission mechanism. The rotating shaft 9 drives the screening funnel 4 to vibrate up and down at a small amplitude and high frequency through the vibration mechanism. The debris in the granular bacterial agent falls to the upper port of the rotating tube 6 through the sieve holes of the screening funnel 4 and the slope of the closed funnel 2 in sequence. The rotating conveying spiral disk 10 conveys the debris to the lower port of the rotating tube 6 and discharges it.

[0056] Step 4: After all the debris in the granular microbial agent in the material tank 1 has been completely screened and discharged, turn off the regulating transmission mechanism;

[0057] Step 5: After the granular microbial agent in material tank 1 has been sprayed out, pour in a sufficient amount of granular microbial agent again to facilitate the continued spraying of the granular microbial agent.
