Description

Technical Field

[0001] The invention relates to the technical field of workpiece processing, in particular to a water-fertilizer ratio control mechanism. Background Art

[0002] Integrated water and fertilizer use a pressure system (or natural terrain height difference) to mix soluble solid or liquid fertilizers according to the soil nutrient content and the fertilizer requirements and characteristics of the crop type. The fertilizer solution is then mixed with irrigation water through a controllable pipe system to supply water and fertilizer. After the water and fertilizer are mixed, sprinkler irrigation or drip irrigation is formed through pipes and drippers to evenly, regularly and quantitatively infiltrate the crop root development and growth area.

[0003] In the existing method of mixing fertilizer and water, fertilizer is poured into the water supply pipe, and then water is transported to the location where fertilizer is needed through the water supply pipe. Due to the different types of fertilizers to be applied, different fertilizers need to be added to the water supply pipe. The water supply pipe is centrally pumped by a pumping device. After filtering, multiple fertilizers are directly added to the water supply pipe. The fertilizers stick to each other, which is not convenient for rapid dissolution and mixing with the water in the water supply pipe. In addition, due to the different dissolution conditions of the fertilizers, some of the fertilizers in the water supply pipe are dissolved and some are not dissolved. Putting fertilizers in batches is likely to cause the dissolved fertilizers to be directly discharged from the water supply pipe, which is not conducive to the subsequent fertilizer configuration and dissolution. For this reason, we propose a water-fertilizer ratio control mechanism. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-10 The present invention provides a technical solution: a water-fertilizer ratio control mechanism, which is used to solve the problem that when preparing water-fertilizer mixture, fertilizer is not fully dissolved, fertilizer types and quantities are different, resulting in uneven mixing. The design includes a pumping device 1, as shown in the attached Figure 1As shown in the figure, the pumping equipment 1 is connected by two pumps, and the pumping pipe is plugged into the pool to pump water. The pumping equipment 1 is connected with a pumping pipe 11, and a plurality of filter tanks 12 are distributed on one side of the pumping equipment 1. The upper part of the filter tank 12 is connected to the pumping pipe 11. The filter tank 12 is an existing product, which mainly plays a filtering effect. When the pumping equipment draws water, it is passed from the upper part of the filter tank 12. After the filter tank 12 is filtered, the lower part of the filter tank 12 is connected with a delivery pipe 13, and then the water is transported from the delivery pipe 13. In this scheme, The filter tank 12 is designed to be distributed in three groups in sequence. The delivery pipe 13 is externally connected to a pretreatment pipe 2, and multiple laminated filters 21 are connected to the pretreatment pipe 2. The water from the laminated filters 21 enters the filter through the filter water inlet. When passing through the filter laminates, the filter laminates are tightly pressed together under the action of spring force and water force, and the impurity particles are trapped at the intersection of the laminates. The filtered water flows out from the main channel of the filter. At this time, the one-way diaphragm valve is in an open state, so that the water filtered by multiple filter tanks 12 is mixed and filtered. One end of the pretreatment pipe 2 is connected to a mixing pipe 3, and one end of the mixing pipe 3 is connected to an irrigation pipeline group 4;

[0029] In order to mix the fertilizers, a plurality of barrels 5 for filling fertilizers are distributed outside the mixing tube 3. The barrels 5 are arranged according to the type of fertilizers to be added and the order of addition (for example, if three different fertilizers A, B, and C need to be filled and added in the corresponding order, three groups of barrels 5 are arranged, and the fertilizers A, B, and C are sequentially loaded into the three barrels 5). A stirring component 6 is arranged inside the barrel 5. The stirring component 6 is designed as a plurality of barrels 5 are connected to the outside with a bracket plate 61, and a plurality of mounting plates 62 are connected to the bracket plate 61, and the mounting plate 62 is located at the top of the barrel 5. The stirring component 6 includes a mounting plate 62. A rotating seat 63 on the mounting plate 62 is connected to a rotating rod 64, a roller 65 is connected to the top of the rotating rod 64, a boss plate 66 is connected to the bracket plate 61, and a transmission rod 67 is connected to the boss plate 66, one end of the transmission rod 67 is connected to the roller 65, and the other end of the transmission rod 67 is connected to a first bevel gear 68, a motor 69 is installed on the outside of one barrel 5, and a second bevel gear 691 meshing with the first bevel gear 68 is connected to the output end of the motor 69, and multiple rollers 65 are driven by belts 651, and multiple stirring crank rods 641 are connected to the rotating rod 64. Multiple recessed areas are distributed on the rotating rod 64.

[0030] A shifting ball 642 is installed at the bottom of the rotating rod 64 , and a plurality of groove holes are formed on the outside of the shifting ball 642 .

[0031] Driven by the motor 69, the second bevel gear 691 rotates with the first bevel gear 68, so that the transmission rod 67 starts to rotate. Because the roller 65 installed on the top of the transmission rod 67 and the roller 65 installed on the top of the rotating rod 64 are both driven by the belt 651, the rotating rod 64 drives the stirring rod 641 to stir the fertilizer inside the barrel. Since the surface design of the rotating rod 64 consists of multiple recessed areas, during the stirring process, it is necessary to press the recessed areas to slide up and down, which is convenient for full contact with the stirring rod 64, thereby improving the stirring effect of the fertilizer.

[0032] When the fertilizer is stirred, because the transmission member 8 includes a bracket body 81 installed on the bracket plate 61, the upper part of the bracket body 81 is connected to a cross bar 82, and the lower part of the bracket body 81 is installed with an inclined rod 83, one end of the cross bar 82 is connected to a third bevel gear 84, and the top of one of the rotating rods 64 is installed with a fourth bevel gear 85 that meshes with the third bevel gear 84, and the other end of the cross bar 82 is installed with a first bevel gear 86, and one end of the inclined rod 83 is connected with a second bevel gear 87 that meshes with the first bevel gear 86, and the bottom of the inclined rod 83 is installed with a transmission gear 88, and the outside of the plurality of rotating sleeves 73 is connected with a rack belt 89 that meshes with the transmission gear 88.

[0033] When the rotating rod 64 rotates, the third bevel gear 84 is driven to rotate by the fourth bevel gear 86, so that the cross bar starts to rotate, and then the second bevel gear is driven to rotate by the first bevel gear 86, so that the bevel rod 83 starts to rotate along the lower part of the bracket body 81, and the transmission gear 88 on the bevel rod 83 drives the rack belt 89 to start moving, thereby realizing the feeding of the feed elbow 51.

[0034] A feed elbow 51 is provided at the bottom of the barrel 5, a flow detection probe 52 is installed at the mouth of the feed elbow 51, a propulsion component 7 is provided inside the feed elbow 51, and a plurality of feed elbows 51 are externally connected to a transmission component 8, and the transmission component 8 is connected to the stirring component 6;

[0035] The designed propulsion component 7 includes an annular block 71 installed on the feed elbow 51, a connecting plate 72 is connected inside the annular block 71, and a rotating sleeve 73 is installed on the annular block 71, a propulsion rod 74 is installed in the middle of the connecting plate 72, and propulsion vanes 76 are distributed outside the propulsion rod 74. A guide curved rod 75 is installed at the bottom of the propulsion rod 74, and one end of the guide curved rod 75 is at the bottom of the toggle ball 642. When the rack belt 89 starts to rotate, the rotating sleeve 73 is driven to rotate at this time, because the rotating sleeve 73 is installed outside the annular block 71, and the annular block 71 is engaged on the feed elbow 51, so that the connecting plate 72 inside the annular block 71 starts to rotate. Since the propulsion rod 74 is fixedly installed on the connecting plate 72, at this time, the propulsion vanes 76 start to rotate. At the same time, since the guide curved rod 75 is fixed at one end of the bottom of the propulsion rod 74, in the process of the guide curved rod 75 starting to rotate, the fertilizer in the barrel 5 is stirred to the bottom inlet of the feed elbow 51. When the fertilizer When a lot of materials are accumulated, the rotating propulsion blades 76 push the fertilizer from the feed elbow 51 into the mixing tube 3. Since the discharge port of the feed elbow 51 is designed to be spherical, it is convenient to concentrate the fertilizer after being pushed. After the flow detection probe 52 outside the spherical feed elbow 51 detects the storage flow inside the elbow, when the discharged fertilizer flow is too large, it is necessary to temporarily block the mixing tube 3 to facilitate the mixing of the fertilizer in the water. When the discharged fertilizer flow is small, the mixing tube 3 needs to be fully opened to facilitate the mixing of the fertilizer pushed in the next step.

[0036] A plurality of mixing zones are distributed on the mixing tube 3, and the mouth of the feed elbow 51 is inserted in the mixing zone. A retractable isolator 9 is connected inside the mixing tube 3, and a movable magnetic ball 91 is installed on the isolator 9 at the mixing zone, and electromagnetic sheets 31 are distributed outside the mixing tube 3.

[0037] The mixing zone includes a straight-through pipe 32 and a spherical pipe 33. The straight-through pipe 32 is distributed in front of the spherical pipe 33. The isolation member 9 includes a plurality of sliding bars 92. One end of the plurality of sliding bars 92 is connected to a mounting block 93. The mounting block 93 is connected to a connecting rod 94 connected to the inner wall of the mixing pipe 3. The sliding bar 92 is located at the spherical pipe 33 and is a retractable elastic bar 95. The movable magnetic ball 91 moves in the straight-through pipe 32.

[0038] After the extracted water is filtered, it first enters the straight pipe 32. At the same time, after the first processed fertilizer is pushed forward, the flow rate stored inside the curved pipe is detected by the flow detection probe 52. When the flow rate is too large, more fertilizer is discharged at this time. At this time, the electromagnetic sheet 31 is controlled to produce the same magnetic pole as the moving magnetic ball 91, so that the elastic strip 95 shrinks in the spherical pipe 33, which is convenient for blocking the fertilizer, and then facilitating the full mixing of the fertilizer and water. After the fertilizer mixing is completed, the detection probe 52 detects that the flow rate stored inside the curved pipe is reduced, so the electromagnetic sheet 31 is controlled to produce the opposite magnetic pole to the moving magnetic ball 91, so that the moving magnetic ball 91 moves toward the straight pipe 32, and the spherical pipe 33 is completely opened, so that the mixed fertilizer and the fertilizer to be mixed in the next step are mixed.

[0039] The barrel 5 is provided with a pouring port 53 .

[0040] The irrigation pipe group 4 includes a vertical pipe 41 connected to the mixing pipe 3 , a pipe valve 42 is installed on the vertical pipe 41 , one end of the vertical pipe 41 is connected to a transverse pipe 43 , and a plurality of irrigation pipes 44 are distributed on the transverse pipe 43 .

[0041] By mixing the fertilizer and water in batches, the effect of separate mixing treatment is achieved. At the same time, the mixing and stirring effect is controlled in real time according to the flow rate passing through. At the same time, the designed moving magnetic ball 91 drives the elastic bar 95 to tighten or open when the sliding bar 92 slides, thereby changing the space area in the mixing tube 3 and adjusting the movement effect of the fertilizer and water after mixing in the mixing tube 3.
