Description

Technical Field

[0001] The present invention relates to the technical field of fertilizing devices, and particularly relates to a special fertilizing device for biological fertilizers. Background Art

[0002] Biological fertilizers, also known as microbial fertilizers, refer to a class of fertilizer products that take the life activities of microorganisms as the core and enable crops to obtain specific fertilizer effects. There is an essential difference between microbial fertilizers and micronutrient fertilizers: the former are living organisms, while the latter are mineral elements. Microbial resources are rich, with a wide variety of types and functions, and can be developed into fertilizers with different functions and uses. Existing fertilizing devices require higher fertilization uniformity. Otherwise, the microbial flora will be overly concentrated, which not only affects the rapid growth of the colonies but also greatly reduces the fertilizer effect they can produce. In particular, the microorganisms in biological fertilizers have requirements for the growth environment and cannot be applied randomly like traditional fertilizers. For example, the Chinese invention patent with the patent publication number CN119344051A solves the problem of fertilization uniformity.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1 - 10As shown in the figure, the present invention is a special fertilizing device for biological fertilizers, including a storage tank 1. Installation frames 2 are fixedly installed at both ends of the storage tank 1. Biological fertilizers are stored in the storage tank 1. A moving wheel 3 is rotatably installed at one end of the installation frame 2 away from the storage tank 1. The moving wheel 3 facilitates the rolling fertilization of the storage tank 1 in the soil. A quantitative component 4 for quantitative fertilization is arranged on the storage tank 1; The quantitative component 4 includes a plurality of material discharge holes 411 formed in the inner bottom wall of the storage bin 1. The material discharge holes 411 facilitate the discharging and fertilizing of biological fertilizer. A support column 410 is slidably installed through the material discharge holes 411. One end of the support column 410 close to the storage bin 1 is fixedly installed with a top plate 41. The top plate 41 serves to block the material discharge holes 411. The other end of the support column 410 is fixedly installed with a frustum 47. The frustum 47 can not only block the material discharge holes 411 but also facilitate the dredging of material discharge. A connecting plate 46 is fixedly installed on the side of the plurality of frustums 47 away from the support column 410. The connecting plate 46 facilitates driving the frustums 47 to move upward synchronously, so that the frustums 47 drive the top plate 41 to open the material discharge holes 411 through the support column 410 for discharging operation. A support plate 49 is fixedly installed on the outer surface of the support column 410. The support plate 49 is slidably installed in the material discharge holes 411.

[0023] Working principle of the present invention: When using the device, first install the material storage box 1 on the driving device, and then pour the biological fertilizer into the material storage box 1. The biological fertilizer flows into the material storage box 1 under the diversion of the material distribution arc plate 51. Then, the driving device drives the moving wheels 3 on the material storage box 1 to roll on the land. At the same time, start the first motor 414 to drive one of the belt pulleys 412 to rotate. One of the belt pulleys 412 drives the other belt pulley 412 to rotate synchronously through the belt 413. At the same time, the belt pulley 412 drives the eccentric wheel 45 to rotate and squeeze the connecting plate 46, so that the connecting plate 46 drives the frustum 47 to squeeze the second spring 48, making the second spring 48 in a compressed state. The frustum 47 drives the support column 410 to slide in the feeding hole 411 and lift the top plate 41. At the same time, the support column 410 drives the support plate 49 to slide in the feeding hole 411. At the same time, the biological fertilizer in the material storage box 1 flows out of the feeding hole 411 through the gap between the two support plates 49 and drops onto the spreading plate 43. When the protruding end of the eccentric wheel 45 turns to the spreading plate 43, the elastic restoring force of the second spring 48 drives the top plate 41 to block the top plate 41 through the frustum 47 and the support column 410. At the same time, the protruding end of the eccentric wheel 45 squeezes the spreading plate 43, making the spreading plate 43 stretch the first spring 44. When the protruding end of the eccentric wheel 45 turns past the spreading plate 43, the elastic restoring force of the first spring 44 drives the spreading plate 43 to vibrate and fertilize. At the same time, start the second motor 52, and the output end of the second motor 52 drives the bidirectional screw 512. The bidirectional screw 512 drives the moving block 57 to move on the double-sided toothed plate 53. The moving block 57 drives the slider 55 to slide on the rectangular through hole 54. At the same time, the moving block 57 drives the first gear 56 to rotate meshingly on the double-sided toothed plate 53 through the extension plate 58. At the same time, the first gear 56 drives the rotating rod 59 to rotate on the extension plate 58. At the same time, the rotating rod 59 drives the dispersing rod 510 and the dispersing block 511 to rotate and disperse in the material storage box 1, so that the rotating rod 59 rotates and disperses during the moving process; when the material storage box 1 moves, it drives the soil covering plate 61 to cover the soil on the biological fertilizer through the mounting plate 64. Then, start the third motor 69, and the output end of the third motor 69 drives the third gear 68. The third gear 68 meshes and drives the second gear 67 to rotate. The second gear 67 drives the reciprocating screw 63 to rotate in the soil covering plate 61. The reciprocating screw 63 drives the reciprocating ring 65 to reciprocate in the soil covering plate 61. At the same time, the first gear 56 drives the mud scraping plate 66 to reciprocate on the outer surface of the soil covering plate 61 to scrape mud.
