Description

Technical Field

[0001] The present invention relates to the technical field of agricultural planting, and specifically relates to a uniform fertilization device for millet planting. Background Art

[0002] Fertilization refers to the agricultural technical measure of applying fertilizers to the soil or spraying them on plants to provide the nutrients required by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, fertilize the soil, and increase economic benefits. Therefore, reasonable and scientific fertilization is one of the main means to ensure food security and maintain the sustainable development of agriculture. The main basis for fertilization is the soil fertility level, crop type, target yield, climate environment, and fertilizer characteristics, so as to select the appropriate fertilizer, estimate the required fertilizer dosage, and determine the fertilization time and fertilization mode.

[0003] Publication No. CN214282146U discloses a uniform fertilization device for millet planting. By pouring fertilizers and water into the feed pipe, at this time, the fertilizers and water fall into the fertilizer tank through the feed pipe. Then, turning the handle drives the stirring rod to rotate in the fertilizer tank to stir the fertilizers, so that different fertilizers are mixed more evenly, and the fertilization effect is better. When the walking wheels are moving, the discharge valve on the discharge pipe is opened. At this time, the liquid fertilizer will enter the hollow cavity of the spraying plate through the discharge pipe, and the liquid fertilizer is evenly sprayed through the nozzles at the bottom of the spraying plate. Fertilization is carried out according to the uniform rotation of the walking wheels, so as to achieve equidistant fertilization. The fertilizers are applied more evenly, which is beneficial to the normal growth of crops, ensures the health of crops, and is very convenient to use. However, the following problems still exist in the actual use of this patent: Although the uniform fertilization device for millet planting can achieve uniform stirring of fertilizers, it cannot adjust the nozzles according to the growth conditions and growth height of millet, resulting in the inability to make the fertilizers fall to the root areas of millet during millet fertilization, thus affecting the fertilization effect. At the same time, the spacing of the walking wheels cannot be adjusted, and it cannot adapt to millet planting fields with different spacings. At the same time, it cannot clean weeds, which affects the fertilization effect.

[0004] Therefore, a uniform fertilization device for millet planting is proposed to solve the problems raised above. Summary of the Invention

At the same time, by using the universal wheels, the fertilization device can shuttle in millet planting fields with different spacings for fertilization operations of millet. The specific content is as follows: 1. By setting up the fertilizing mechanism, not only can the first rotating motor be used to drive the rotating main gear to rotate, and by utilizing the meshing connection between the rotating main gear and the rotating tooth disc, the rotating tooth disc can drive the connecting column and the spray pump to rotate. Through rotation, uniform fertilization of millet can be achieved. By starting the first electric telescopic rod to drive the opening and closing bracket to move up and down, under the action of the opening and closing rotating rod, the opening and closing rotating rod can drive the opening and closing slider to slide in the opening and closing sliding groove inside the opening and closing bracket, so that the opening and closing slider drives the inclined nozzle to move relatively, thereby being able to adjust the position of the inclined nozzle, thus adapting to millet of different growth sizes.

[0024] Working principle: Before using this uniform fertilization device for millet planting, it is necessary to first check the overall situation of the device to ensure that it can work normally.

At the same time, the fertilizer applicator can shuttle through the millet planting fields with different spacings by means of the universal wheels 212 to perform the fertilizer application operation for millet. By rotating the lifting knob 205, the lifting double-threaded rod 206 is driven to rotate, so that the lifting thread sleeve 207 moves relatively on the outside of the lifting double-threaded rod 206 and drives the lifting rotating rod 208 to rotate, thereby enabling the adjustment of the distance between the top lifting bracket 204 and the bottom lifting bracket 211. By changing the height of the adjusting bracket 201, fertilizer can be applied to millet with different rising heights at different growth stages. Before adjusting the spacing of the top lifting bracket 204, by pressing the top of the unlocking rotating rod 221, under the action of the unlocking bracket 220, the separation of the fixed pin 223 and the fixed block 224 can be realized, and the rotating sleeve 219 can be opened to facilitate the relative sliding of the first sliding rod 214 and the second sliding rod 215. By utilizing the characteristic that the rotating sleeve 219 is engaged with the second sliding rod 215, the fixing of the second sliding rod 215 can be realized, which is convenient for the stable movement of the top lifting bracket 204 and improves the stability of fertilizer application.

[0025] Secondly, by opening the feeding box door 127, fertilizer can be put into the inside of the mixing box 124. The second rotating motor 129 is started to drive the rotating worm 130 to rotate. By utilizing the meshing connection between the rotating worm 130 and the rotating worm gear 131, the rotating connection ring 132 drives the top rotating disc 133, the mixing lifting column 134 and the bottom rotating disc 135 to rotate, thereby realizing the rotation of the mixing filter plate 136 and the mixing auger 137, which is convenient for mixing the fertilizer. At the same time, the third rotating motor 138 is started to drive the rotating threaded rod 139 to rotate, and the up and down movement of the mixing filter plate 136 can be realized. This not only facilitates the full mixing of the fertilizer, but also enables the observation of whether there is fertilizer residue on the mixing filter plate 136, which is convenient for the full mixing of the fertilizer.

[0026] Finally, the first rotating motor 104 is used to drive the rotation of the main rotating gear 105. By virtue of the meshing connection between the main rotating gear 105 and the rotating gear disk 101, the rotating gear disk 101 drives the connecting column 106 and the spraying pump 107 to rotate. Uniform fertilization of millet can be achieved by rotation. By starting the first electric telescopic rod 109, the opening and closing bracket 110 is driven to move up and down. Under the action of the opening and closing rotating rod 114, the opening and closing rotating rod 114 drives the opening and closing slider 112 to slide in the opening and closing sliding groove 111 inside the opening and closing bracket 110, so that the opening and closing slider 112 drives the inclined nozzle 113 to move relatively, thereby being able to adjust the position of the inclined nozzle 113 to adapt to millet of different growth sizes. By virtue of the meshing connection between the rotating gear disk 101 and the driven rotating gear 115, the rotation of the rotating connecting rod 116 can be achieved. The rotating connecting rod 116 drives the square lifting column 117 and the second electric telescopic rod 118 to rotate. The square lifting column 117 drives the square lifting sleeve 119 to rotate. The weed is cleared by the weed whipping rope 122 inside the weed whipping disk 120. At the same time, the second electric telescopic rod 118 can be used to realize the sliding of the square lifting sleeve 119. By changing the height of the weed whipping disk 120, it is convenient to clear the weed. By rotating the adjusting knob 123 to drive the winding column 121 to rotate, the length of the weed whipping rope 122 can be adjusted, which is convenient for clearing weeds at different positions.

Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
