Description

Technical Field

[0001] The invention relates to the technical field of agriculture, in particular to an automatic fertilizing device for water and fertilizer crops. Background Art

[0002] Water fertilizer refers to fertilizer made from decomposed human feces and urine plus water. In a narrow sense, it is fertilization through an irrigation system, and crops absorb nutrients while absorbing water. Fertilization, which is usually carried out simultaneously with irrigation, is achieved by injecting fertilizer solution into the irrigation water pipe under pressure. The irrigation water with fertilizer is sprayed on the crops or dripped into the root zone through the sprinkler. In a broad sense, it is to dissolve the fertilizer and then apply it, including sprinkling, pouring, spraying, and pipe application. Water-fertilizer integration is simply to carry out irrigation and fertilization at the same time. It is to irrigate crops through pipes after mixing irrigation water and liquid fertilizer in a reasonable ratio through the pipe system. The equipment can reasonably allocate different crops and different seasons according to different fertilization needs in a certain proportion, which is more scientific than manual fertilization.

[0003] When developing new crops, in order to provide a good growth environment for new crops, it is necessary to irrigate and fertilize them to ensure the successful development of new varieties of crops. Traditional irrigation and fertilization often have many disadvantages. For the crops planted, watering is often based on feeling, and fertilization is based on experience, which often leads to the crops "eating for a few days and starving for a few days" and cannot be reasonably "eaten and drunk". The integrated water and fertilizer irrigation equipment can make a reasonable analysis based on the crops planted, and then set a standardized fertilization and irrigation plan;

[0004] In the prior art, integrated water and fertilizer fertilization is carried out on crops through traditional fixed irrigation systems, but the irrigation and fertilization effect is poor, and dead corners are easily present during the irrigation process. In addition, existing fertilization devices mostly fertilize crops and the soil surface, which makes it difficult for crop roots to absorb fertilizer, reduces the fertility of the deep soil, and causes unsatisfactory fertilization effects, thereby reducing the success rate of cultivating new varieties of crops. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic water-fertilizer crop fertilization device to at least solve the problems that the prior art water-fertilizer integration fertilizes and irrigates crops through a traditional fixed irrigation system, the irrigation and fertilization effect is poor, dead corners are easily present during the irrigation process, and the existing fertilization devices mostly fertilize crops and the soil surface, resulting in difficulty in crop root absorption, reduced fertility in the deep soil, and unsatisfactory fertilization effect.

[0060] By those skilled in the art, all electrical components in this case can be connected to an externally adapted power supply through wires, and an adapted external controller should be selected for connection according to the specific actual usage conditions to meet the control requirements of all electrical components. The specific connection method and control sequence should refer to the following working principle, in which the electrical components complete the electrical connection in the order of working in sequence. The detailed connection means are well-known technologies in the art and will not be explained here. The following mainly introduces the working principle and process, and the specific work is as follows.

[0061] Step 1: When in use, the staff will inject water and fertilizer liquid into the pump body 7 in advance, and the control box 8 will start the first motor 35, the second motor 311 and the third motor 315 in sequence. The first motor 35 drives the first gear 36 to rotate clockwise or counterclockwise. Since the first gear 36 and the first rack 37 are meshed, the first gear 36 is prompted to move to the left or rearward along the outer wall of the first rack 37 under the action of its own rotational force, and the first movable seat 33 drives the mounting frame 38 under the limiting action of the first guide wheel 34 to drive the internal fertilization mechanism 5 and the spray pipe 4 to move to the designated position in the left and right horizontal directions respectively under the cooperation of the first movable seat 39, the mounting seat 314, the limiting seat 318 and the first lead screw nut 317. The second motor 311 drives the second gear 312 to rotate clockwise or counterclockwise. Since the second gear 312 and the second rack 313 are meshed, the second gear 312 is prompted to move along the second rack under the action of its own rotational force. The outer wall of 313 moves to the left or rear side, and the first moving seat 39 drives the internal fertilization mechanism 5 and the spray pipe 4 to move horizontally to the designated position in the front and rear directions respectively under the limiting action of the second guide wheel 310 and the cooperation of the limiting seat 318 and the first screw nut 317. The third motor 315 drives the first screw rod 316 to rotate clockwise or counterclockwise. Since the first screw rod 316 and the first screw nut 317 are screwed together, the first screw nut 317 is driven to move upward or downward to a designated height position under the action of the rotation force of the first screw rod 316, and under the limiting action of the limiting seat 318, the first screw nut 317 drives the internal fertilization mechanism 5 and the spray pipe 4 to move up and down to the designated height position respectively. The staff controls the control box 8 to start the pump body 7, and the pump body 7 pumps the water and fertilizer liquid inside itself into the spray pipe 4, so as to spray the crops at the designated positions inside the incubator 2 in sequence, increase the spraying area, and avoid the existence of fertilization dead corners;

[0062] Step 2: When it is necessary to fertilize the roots of crops inside the incubator 2 or to fertilize the deep soil, the staff controls the moving mechanism 3 to drive the internal fertilization mechanism 5 to drive the soil internal injection assembly 6 to move to the specified position, inserts the pin 62 into the soil and fixes it, and enables the pump body 7 to pump the internal water fertilizer liquid into the storage tube 54. The staff controls the control box 8 to start the micro electric push rod 65, and the micro electric push rod 65 pushes the depth injection assembly 63 downward by its own extension, thereby extending the depth injection assembly 63 out of the inner cavity of the shell 61. The staff controls the control box 8 to start the fourth motor 55, the three-way electric control valve 636 and the micro motor 6311. The fourth motor 55 drives the second lead screw 56 to rotate clockwise. Since the second lead screw nut 57 and the second lead screw 56 are screwed together, the second lead screw nut 57 is prompted to move downward under the action of the rotational force of the second lead screw 56, and under the limiting action of the limiting slider 53, the second lead screw nut 57 drives the injection The piston 58 of the storage tube 54 moves downward in the inner cavity of the storage tube 54, so as to push the water fertilizer liquid in the storage tube 54 into the three-way electric control valve 636 along the telescopic tube 64 under the action of pressure, and then the water fertilizer liquid is discharged into the bottom nozzle tube 635 in sequence under the diversion of the three-way electric control valve 636. The micro motor 6311 drives the driving gear 6312 to rotate. Since the inner gear ring 6310 and the driving gear 6312 are engaged, the inner gear ring 6310 is driven by the rotation force of the driving gear 6312. The rotating disk 637 rotates, and the rotating disk 637 drives the limiting slide groove 638 to rotate, so that the limiting pin 639 drives the slider 634 under the action of the rotation force of the limiting slide groove 638, so that the slider 634 moves outward under the limiting action of the slide groove 633 at the corresponding position, and then the slider 634 drives the bottom nozzle pipe 635 at the corresponding position to extend from the inner cavity of the plug hole 6313 and insert into the outer soil, so that the water fertilizer liquid is injected deeper into the soil along the bottom nozzle pipe 635;

[0063] In summary, the technical solution can realize automatic fertilization and irrigation of water and fertilizer for crops and adjust the designated irrigation position and direction, avoid dead corners and omissions during fertilization and irrigation, improve the effect of irrigation and fertilization, and can realize direct fertilization of the roots of crops in the soil without the need for water and fertilizer to penetrate the soil, thereby improving the absorption effect of water and fertilizer by crops, increasing the deep fertility of the soil, and improving the success rate of cultivating new varieties of crops.
