Description

Technical Field

[0001] The invention relates to the technical field of crop planting equipment, and in particular to automatic fertilization equipment for crop planting with uniform spreading. Background Art

[0002] Crops are various plants cultivated in agriculture, including food crops and cash crops (oil crops, vegetable crops, flowers, grasses, and trees). The growth of crops is inseparable from scientific and technological production technologies, as well as mechanical equipment manufactured by new industries to assist agricultural production. Fertilization is an agricultural technical measure, which refers to applying fertilizer to the soil or spraying it on plants to provide the nutrients needed by plants and maintain and improve soil fertility. The main purpose of fertilization is to increase crop yields, improve crop quality, improve soil fertility, and improve economic benefits. Therefore, reasonable and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. Therefore, in order to increase crop yields and improve crop quality during the planting process, crops usually cannot do without fertilization.

[0003] At present, most of the automatic fertilization equipment for crop planting on the market directly sprays fertilizers or sprinkles fertilizers on the soil during the crop planting process. This method is not only not conducive to the absorption of fertilizers by crops and soil, but also cannot well control the amount of fertilizer spread, which may lead to uneven fertilizer spread, affecting the growth environment of crops, causing uneven growth of crops, and thus reducing yields. In addition, in agricultural production, mixed fertilizers are sometimes required for fertilizing crops. At present, most of the automatic fertilization equipment for crop planting on the market only have a single spreading effect and do not have the function of mixing fertilizers. Multiple fertilizers need to be mixed manually before fertilization, which makes fertilization inconvenient. Fertilizers may have different particle sizes, and may be accumulated in the fertilizer box during the spreading process. Layering may occur as the equipment vibrates, resulting in unsatisfactory subsequent fertilization effects. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose an automatic fertilizing equipment for crop planting with uniform spreading, which can spread the required fertilizer into the soil in a quantitative and uniform manner, so that the crops and soil can absorb the fertilizer, and the amount of fertilizer spread can be better controlled, thereby alleviating the problem of uneven fertilizer spreading, affecting the growth environment of crops, causing uneven growth of crops, and thus reducing the yield. In addition, the equipment can mix a variety of fertilizers before fertilization, and during the fertilization process, the fertilizers can be turned over and mixed while being spread, thereby alleviating the need for manual mixing of a variety of fertilizers before fertilization, which makes fertilization more inconvenient.

[0047] The rotating rod 913 is rotatably connected to the middle part of the mixing barrel 93, and multiple mixing plates 914 are arranged on the lower side of the support seat 911, and multiple mixing plates 914 are arranged inside the mixing barrel 93. The outer wall of the mixing barrel 93 is fixedly connected with a bucket 94. The mixing barrel 93 and the bucket 94 are fixedly connected to the inside of the carrier frame 91. When only a single fertilizer needs to be sown, the cover plate 916 is opened, and the fertilizer to be sown is poured into the bucket 94. The fertilizer can slide into the mixing barrel 93 along the bucket 94, and then slide into the end of the conveying pipe 96 close to the motor 97. The motor 97 is started to drive the conveying roller 98 to rotate, and the fertilizer dropped in the mixing barrel 93 is pushed to the fertilizer outlet pipe 910, so that the fertilizer can be passed through The fertilizer falls into the fertilizer box 7 through the fertilizer outlet pipe 910, and the motor 912 is started at the same time, driving the rotating rod 913 to drive the mixing plate 914 to rotate, so as to stir the fertilizer in the mixing barrel 93 to prevent the fertilizer in the mixing barrel 93 from sticking and clogging, and to facilitate the fertilizer to remain dispersed before sowing, so as to facilitate the subsequent quantitative and uniform sowing. When it is necessary to sow mixed fertilizers and mix the fertilizers, one type of fertilizer can be poured into the mixing barrel 93 through the bucket 94 first, and then the meniscus 917 can be opened to pour the remaining types of fertilizers into the feeding barrel 95 in turn, and the remaining types of fertilizers can gradually slide into the mixing barrel 93 through the connecting pipe 915 in turn, and be tumbled and mixed in the mixing barrel 93 under the stirring of the mixing plate 914.

[0051] Working principle: Before using this equipment, connect this equipment to the driving device through the connecting frame on the front side of the main frame 11, so that the equipment can be pulled by the driving device to facilitate subsequent work. When it is necessary to fertilize a certain planting area, pull this equipment in the required fertilization area so that the fertilization tillage knife 12, the tillage knife 14 and the ridge dividing knife 15 are staggered with the crops. When only a single fertilizer needs to be sown, open the cover 916, pour the fertilizer to be sown into the bucket 94, and the fertilizer can slide along the bucket 94 into the mixing barrel 93, and then slide into the end of the conveying pipe 96 close to the motor 97, start the motor 97, drive the conveying roller 98 to rotate, and push the fertilizer dropped in the mixing barrel 93 to the fertilizer outlet pipe 910, so that the fertilizer can pass through the fertilizer outlet pipe 910 falls into the fertilizer box 7, and the motor 912 is started at the same time, driving the rotating rod 913 to drive the mixing plate 914 to rotate, so as to stir the fertilizer in the mixing barrel 93 to prevent the fertilizer in the mixing barrel 93 from sticking and clogging, and also facilitate the fertilizer to remain dispersed before sowing, so as to facilitate the subsequent quantitative and uniform sowing. When it is necessary to sow mixed fertilizers and mix the fertilizers, one type of fertilizer can be poured into the mixing barrel 93 through the bucket 94 first, and then the meniscus 917 is opened to pour the remaining types of fertilizers into the feeding barrel 95 in turn, and the remaining types of fertilizers gradually slide into the mixing barrel 93 through the connecting pipe 915 in turn, and are stirred and mixed in the mixing barrel 93 under the stirring of the mixing plate 914, so that the device can mix multiple fertilizers before fertilization and mix them during fertilization. During the process, the fertilizer is stirred and mixed while being spread, which alleviates the need to manually mix multiple fertilizers before fertilization, which makes fertilization inconvenient. Fertilizers may have different particle sizes, and may be accumulated in the fertilizer box during the spreading process. Layering may occur as the equipment vibrates, resulting in unsatisfactory subsequent fertilization effects. When the equipment moves, the rolling wheel 36 rotates with the movement of the equipment through the fixed plate 310 and the ground, and then drives the shaft rod 32 and the sprocket wheel 2 33 to rotate through the sprocket wheel four 38, the chain two 39 and the sprocket wheel three 37, and then drives the sprocket wheel one 31 and the rotating rod 5 to rotate through the chain one 34, thereby driving the multiple quantitative wheels 64 on the rotating rod 5 to rotate together, and the fertilizer inside the fertilizer box 7 passes through the through port 8 and the slot 66 and slides along the slide plate 67 into the outer shell 61. On the dosing wheel 64 and the positioning block 63, smaller particles of fertilizer can pass through the space between the upper side of the positioning block 63 and the shell 61 and fall into the fertilizer hopper 62, while larger particles of fertilizer will fall quantitatively in each angle of the outer wall of the dosing wheel 64, and fall quantitatively and uniformly into the fertilizer hopper 62 as the dosing wheel 64 rotates. This method can not only quantify the fertilizer and make the sowing more uniform, but also prevent the fertilizer from clogging the through pipe 68. The larger particles of fertilizer are matched with the smaller particles of fertilizer and finally slide out along the through pipe 68. During the movement, the fertilizing blade 12 breaks the soil next to the crops, and the fertilizer falls into the soil channel along the lower end of the fertilizing blade 12. Then the tilling blade 14 performs secondary tillage to make the fertilizer and the soil roll and mix, which is convenient for the soil to absorb the fertilizer.Finally, the ridge dividing knife 15 levels the plowed soil and pushes the soil carrying fertilizer to the crops on both sides, so that the crops can absorb the fertilizer. In this way, the required fertilizer can be quantitatively and evenly spread into the soil, which is convenient for the crops and soil to absorb the fertilizer. The amount of fertilizer spread can also be better controlled, alleviating the problem of uneven fertilizer spread, affecting the growth environment of crops, causing uneven growth of crops, and thus reducing the yield.

[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
