Thereby improving agricultural production efficiency and reducing production costs. In addition, it can mark the straightness of the tractor forward, so that the tractor driver can ensure that the tractor drives in a straight line according to the mark, reduce the probability of deviation from the track, improve the accuracy and work efficiency of the tractor's driving, and thus improve the effect and efficiency of agricultural operations.

[0015] 2. The present invention ensures the discharge rate and uniformity of fertilizers through the coordination of soil preparation components, fertilizer mounting frames, fertilizer boxes, multiple material leveling components and multiple quantitative components, so that solid fertilizers and liquid fertilizers can fall into the surface soil evenly and quickly, thereby improving the effect of fertilization, and can evenly locate and quantitatively fertilize the soil according to the speed and distance of the tractor, further improving the effect and efficiency of agricultural operations.

Through the real-time identification and monitoring of the quantitative box, it can be discovered in time that the liquid fertilizer and solid fertilizer suddenly have problems such as agglomeration, crystallization or precipitation, which leads to a reduction in delivery amount. Once a problem is found, the quantitative box will send a signal to the control cylinder to retract it, thereby preventing further delivery. At the same time, the quantitative box will also send a reminder to the tractor until the fertilizer in the liquid cavity and the solid cavity reaches the required delivery amount. This allows the present invention to ensure that the fertilizer delivery amount is accurate and uniform, achieve intelligent delivery effects, and improve the effect and efficiency of fertilization.

[0042] For example, in one embodiment: when fertilization is required, solid fertilizer is poured into the solid fertilizer chamber 42, and liquid fertilizer is poured into the liquid fertilizer chamber 43, then the tractor is started, the fertilization device is driven forward by the tractor, and the loosening motor is started synchronously to rotate the loosening shaft 14, and the multiple soil crushing claws 141 on the loosening shaft 14 will crush and overturn the surface soil, and the overturned surface soil will impact the loosening plate 13 and the inner side wall of the loosening mounting plate 11, and the multiple first soil crushing plates 111 and the multiple second soil crushing plates 131 will cause the surface soil to be further crushed and fall between the loosening shaft 14 and the roller 22. With the continuous movement of the tractor, the roller 22 will level the crushed surface soil, and the scraper 23 can prevent the surface soil from adhering to the surface of the roller 22, and prevent the surface soil from adhering too much to the surface of the roller 22 after continuous loosening and leveling operations, thereby hindering the leveling effect. As the tractor continues to move, the soil leveling cones 252 in the multiple soil leveling elements 25 on the soil leveling mounting strip 26 will divide the surface soil after the leveling operation into ridges, thereby realizing automated soil loosening, rolling, leveling and ridge division operations, which can effectively improve the soil structure, increase soil aeration and water permeability, promote root growth, increase crop yield and quality, and enable crop roots to grow better, improve soil utilization, and reduce waste, thereby improving agricultural production efficiency and reducing production costs.

[0043] For example, in one embodiment: when the tractor drives the fertilizer application device forward, the positioning spur wheel 27 will rotate around the spur wheel shaft 212, so that the positioning spur wheel 27 can be used to equidistantly dig holes in the adjacent surface soil, and indicate the direction for the tractor to move forward straight, so that the tractor driver can ensure that the tractor drives in a straight line according to the indication, reduce the possibility of deviation from the track, improve the accuracy and work efficiency of the tractor's driving, and thus improve the effect and efficiency of agricultural operations.

[0044] At the same time, when the spur wheel shaft 212 rotates, its power will be transmitted to the first shaft 324 along the first transmission belt 325, so that the first shaft 324 rotates, thereby causing the paddle wheels 513 on the plurality of solid material equalizing elements 51 to rotate synchronously, so that a negative pressure space is formed at the fourth rotating hole 531 of the solid material equalizing chamber 517, so that the solid fertilizer in the solid fertilizer chamber 42 will be accelerated to fall from the solid material dropping trough 44 along the solid material feeding square tube 511 into the solid material equalizing chamber (5 17), and falls into the fourth rotating hole 531 of the solid material mixing chamber 517, and when the dial wheel 513 rotates, the teeth on the dial wheel 513 will quickly transmit the solid fertilizer to the discharge trough 532, and fall into the discharge pipe 514 through the discharge trough 532. At the same time, some solid fertilizers are not sent out through the discharge trough 532, and will be thrown out under the action of centrifugal force as the dial wheel 513 rotates, and impact the elastic plate 515, so that the elastic plate 515 The elastic plate 515 rotates and bends over the top of the triangular block 533, so that the two ends of the top surface of the elastic plate 515 will abut against the bottom surfaces of the two limiting sealing plates 536, and push the limiting sealing plates 536, so that the limiting sealing plates 536 transmit power to the rotating bar 535, so that the rotating bar 535 rotates around the rotating shaft 519, so that the sealing plate 516 rotates with it, until the two ends of the top surface of the elastic plate 515 are attached to the top surfaces of the two limiting sealing plates 536. At this time, the sealing plate 516 is adjacent to the entire One end of the soil component 20 will also fit against the inner wall of the inclined tube 518, thereby closing the inclined tube 518 to prevent solid fertilizer from leaking out. At the same time, due to the continuous rotation of the thumbwheel 513, the solid fertilizer in the solid fertilizer chamber 42 will fall from the solid feeding square tube 511 into the solid material equalizing chamber 517 more quickly and evenly, and enter the discharge pipe 514 evenly and quickly through the discharge trough 532, thereby ensuring the discharge rate and uniformity of the solid material equalizing element 51.

[0045] In addition, when the first rotating shaft 324 rotates, its power will be transmitted to the second rotating shaft 328 along the second transmission belt 329, so that the second rotating shaft 328 will rotate synchronously, and then the impellers 522 in the plurality of liquid material equalizing elements 52 will rotate synchronously, so that the liquid fertilizer in the liquid fertilizer chamber 43 can be accelerated and uniformly enter the liquid material equalizing chamber 524 through the liquid inlet hole 526 as the impeller 522 rotates, and is uniformly and quickly sent to the liquid guide tube 523 through the liquid outlet groove 527. Subsequently, the liquid fertilizer in the liquid guide tube 523 and the solid fertilizer in the material outlet tube 514 will be sent to the liquid material chamber 613 and the solid material chamber 612 respectively.

[0046] When the first rotating shaft 324 rotates, its power will be transmitted to the third rotating shaft 341 along the third transmission belt 342, so that the third rotating shaft 341 rotates synchronously, and then the multiple trigger rings 343 on the third rotating shaft 341 rotate synchronously. Since one side of the outer wall of the trigger ring 343 is equidistantly provided with multiple gear teeth 344 along the circumferential direction, and the two sides of the control groove 636 are equidistantly provided with multiple control gear teeth 637 along the height direction, and the trigger ring 343 is meshed and connected with the control groove 636, that is, the control bar 631 can perform synchronous reciprocating vertical linear motion under the continuous rotation of the trigger ring 343. When the control bar 631 generates downward power, it will make the quantitative control slide bar 622 move downward along the quantitative control slide groove 621, and then the control cylinder 632 moves downward, and then the control plate 633 moves downward. The two opening and closing rotating rods 634 will rotate downward and outward to open synchronously, and the two opening and closing plates 635 will open synchronously, so that the liquid material chamber 613 and the solid material chamber 612 will open synchronously, so that the liquid fertilizer and solid fertilizer in the liquid material chamber 613 and the solid material chamber 612 will fall into the liquid material separation chamber 644 and the solid material separation chamber 643 respectively, and fall into the liquid fertilizer cylinder 256 and the solid fertilizer cylinder 255 respectively through the liquid discharge pipe 648 and the solid discharge pipe 646, and then fall evenly from the liquid fertilizer cylinder 256 and the solid fertilizer cylinder 255 into the triangular plate 253 respectively, and fall evenly into the surface soil along the inclined top surface of the triangular plate 253 to fertilize the surface soil, so that the present invention can uniformly position and quantitatively fertilize the soil according to the speed and distance of the tractor.

[0047] For example, in one embodiment: the metering box 62 will weigh the liquid fertilizer and solid fertilizer entering the liquid chamber 613 and the solid chamber 612 in real time. When the amount of liquid fertilizer and solid fertilizer in the liquid chamber 613 and the solid chamber 612 suddenly decreases due to solid fertilizer agglomeration, liquid fertilizer crystallization or precipitation, the metering box 62 will recognize this situation in real time and send a signal to retract the output shaft of the control cylinder 632, so that when the control cylinder 632 moves downward, the control plate 633 will not move downward, so that the opening and closing plate 635 will not be opened, and a reminder will be sent to the tractor until the liquid fertilizer and solid fertilizer in the liquid chamber 613 and the solid chamber 612 reach the required amount. The output shaft of the control cylinder 632 will extend rapidly to drive the liquid fertilizer and solid fertilizer to be released, so as to achieve an intelligent release effect.
