Description

Technical Field

[0001] The invention relates to the technical field of saline-alkali land treatment, and in particular to a device and method for saline-alkali land treatment. Background Art

[0002] Soil microorganisms can convert nutrients in saline-alkali soil from ineffective or slow-acting states to effective or fast-acting states. They can also accelerate the humification of nutrients, secrete phytase, and degrade most of the phytate in the soil, thereby achieving the effect of improving saline-alkali soil. At present, microbial fertilizers are mainly made into granules by granulators and evenly distributed in the fields by machine spreading. There are also many ways of machine spreading, such as drones, single-person backpack spray barrels, etc. Among them, single-person backpack spray barrels are the most widely used due to their low cost.

The upper side of the discharge bin 5 is connected with the lower port of the closed funnel 2. The lower port of the rotating tube 6 is rotatably connected to the limiting chassis 8 below the fan-shaped discharge bin 5. The limiting chassis 8 is fixedly connected to the bottom wall of the fan-shaped discharge bin 5. A rotating shaft 9 is arranged in the middle part of the rotating tube 6. The lower end of the rotating shaft 9 is rotatably connected to the limiting chassis 8. The lower end of the rotating shaft 9 extends to the bottom of the limiting chassis 8 and is slidably connected to the limiting chassis 8 in the up and down directions.

[0022] As a further solution of the present invention, the driving mechanism includes a motor 11, which is fixedly connected to the lower side of the closed funnel 2, and 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 through a belt ring 13, and the second pulley 14 is fixedly connected to the outer wall of the rotating tube 6.

[0025] 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 up and down. When the rotating tube 6 rotates, the rotating tube 6 drives the active push plate 15 to rotate, and the driven push plate 16 does not rotate. At this time, the rotating shaft 9 is pushed up a distance by the adjusting component, and the rotating shaft 9 drives the driven push plate 16 to move up to contact with the active push plate 15. The active push plate 15 drives the rotating shaft 9 to rotate by pushing the driven push plate 16, and the rotating shaft 9 drives the conveying spiral disk 10 to rotate, thereby realizing the extrusion and discharge of debris in the granular inoculant.

[0027] When the above scheme is put into actual use, the end of the toggle rod 17 away from the first inclined surface block 18 is toggled backward, and the first inclined surface block 18 is flipped forward under the push of the toggle rod 17, and the inclined surface of the first inclined surface block 18 pushes the rotating shaft 9 to move upward, so that the driven push plate 16 moves up to contact with the active push plate 15, and then the rotating tube 6 drives the rotating shaft 9 to rotate; after the debris in the granular inoculant is completely separated and discharged, the same principle is applied, and the reverse operation is performed to flip the first inclined surface block 18 backward and away from the lower end of the rotating shaft 9, and the rotating shaft 9 slides freely to reset under the action of gravity, so that the driven push plate 16 drops to be offset from the active push plate 15, and then the rotating shaft 9 stops rotating.

[0028] As a further solution of the present invention, the limit locking unit includes two empty slots 19 and an arc-shaped limit frame 22, the two empty slots 19 are respectively opened on the front and rear sides of one end of the toggle rod 17 away from the first inclined block 18, the inner side of the empty slot 19 is slidably connected with a pressure plate 20 in the front and rear directions, and an elastic telescopic rod 21 is fixedly connected between the pressure plate 20 and the empty slot 19, the arc-shaped limit frame 22 is sleeved on the outer side of the toggle rod 17, the arc-shaped limit frame 22 is fixedly connected to the barrel 1, and the arc-shaped limit frame 22 A first locking hole 23 and a second locking hole 24 are respectively provided at the front and rear ends of the upper side wall, and a second inclined surface block 25 is slidably connected to the inner side of the empty slot 19 in the up and down directions.

[0029] When the above scheme is put into practical use, when the end of the toggle rod 17 away from the first inclined surface block 18 is toggled backward, the finger will press the front pressure plate 20, and the front pressure plate 20 will squeeze the front second inclined surface block 25 into the empty groove 19 through the inclined surface of the second inclined surface block 25, so that the front second inclined surface block 25 is separated from the first lock hole 23, and then the toggle rod 17 and the arc-shaped limit frame 22 slide relative to each other. When the toggle rod 17 is pushed to the rear end of the arc-shaped limit frame 22, the first inclined surface block 18 has pushed the rotating shaft 9 up to the set height, and at the same time, the rear second inclined surface block 25 is The inclined surface block 25 moves upward under the elastic force of the first spring 26 until it is just inserted into the second locking hole 24, so that the toggle rod 17 and the arc-shaped limit frame 22 are relatively fixed, and the rotating shaft 9 is kept at the set height; when the end of the toggle rod 17 away from the first inclined surface block 18 is pushed forward, the finger presses the rear pressure plate 20, and the rear pressure plate 20 squeezes the rear second inclined surface block 25 through the inclined surface of the second inclined surface block 25 to retract into the empty groove 19, so that the rear second inclined surface block 25 is separated from the second locking hole 24, so that the toggle rod 17 is relative to the arc-shaped limit frame 22. For sliding, when the toggle rod 17 is pushed to the front end of the arc-shaped limit frame 22, the inclined surface of the first inclined surface block 18 completely leaves 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 surface block 25 on the front side moves up to just insert into the first lock hole 23 under the elastic force of the first spring 26, so that the toggle rod 17 and the arc-shaped limit frame 22 are relatively fixed, thereby keeping the rotating shaft 9 in the reset state; when the hand leaves the pressing plate 20, the pressing plate 20 will automatically reset under the elastic force of the elastic telescopic rod 21; the device can be adjusted by the adjustable transmission mechanism at any time. The screening and extrusion functions of the debris in the granular inoculant can be turned off or on at the same time, so that the user can choose to turn off the screening and extrusion functions of the debris according to the real-time situation to reduce the energy consumption of the device, and the opening and closing operation of the adjustable transmission mechanism is convenient, which can be done by dialing the toggle rod 17 back and forth, and the end of the toggle rod 17 can be automatically fixed in the open or closed position under the action of the limit locking unit without external force collision, thereby ensuring the stability of the closing and opening of the screening and extrusion functions of the debris, and avoiding the situation where the screening and extrusion functions of the debris are stopped or suddenly opened halfway.
