[0019] Embodiment 1

[0020] Referring to Figures 1-4 , a fertilizing device for sandy gravel soil, comprising a vehicle body 1, a connecting frame 5 is fixedly installed on the top of the vehicle body 1, a plurality of tillage plows 3 are fixedly installed on one side of the vehicle body 1, a fertilizer tank 2 is fixedly installed on the top of the vehicle body 1, a water distribution pipe 6 is fixedly installed at the bottom of the vehicle body 1, the water distribution pipe 6 is of a T-shaped structure, one end of the water distribution pipe 6 penetrates the vehicle body 1 and is connected to the fertilizer tank 2 in a through manner, a plurality of outflow pipes 11 are connected to the outside of the water distribution pipe 6 in a through manner, a relative set of tillage plows 3 and a set of outflow pipes 11 are on the same horizontal line, and a quantitative mechanism is provided at one end of each of the plurality of outflow pipes 11. The quantitative mechanism is used to control the fertilizing amount flowing out of the outflow pipe 11 at one time. The quantitative mechanism includes a frame body 10, connecting columns 12 are fixedly installed on both sides of the top of the frame body 10, one ends of the two groups of connecting columns 12 are fixedly installed on the outside of the water distribution pipe 6, a connecting plate 22 is fixedly installed on one side of the bottom of the frame body 10, a bottom plate 14 is fixedly installed on the bottom of the connecting plate 22, sliding grooves 21 are opened on both sides inside the frame body 10, a sliding plate 19 is slidably arranged inside the sliding grooves 21, a through hole 24 is opened on one side of the sliding plate 19, the top of the sliding plate 19 abuts against one end of the outflow pipe 11, the outflow pipe 11 is communicated with the through hole 24, a quantitative pipe 13 is fixedly installed at the bottom of the sliding plate 19, the quantitative pipe 13 is communicated with the through hole 24, a connecting member 17 is movably installed on the outside of the quantitative pipe 13, a blocking plate 15 is fixedly installed at one end of the connecting member 17, the bottom of the blocking plate 15 abuts against the top of the bottom plate 14, and a stress plate 18 is fixedly installed on the outside of the quantitative pipe 13.

[0021] A support frame 7 is fixedly installed at the bottom of the vehicle body 1, a telescopic motor 8 is fixedly installed on one side of the support frame 7, a transmission plate 9 is fixedly installed at the end of the transmission shaft of the telescopic motor 8, and the outside of the transmission plate 9 is fixedly installed with a plurality of stress plates 18.

[0022] Tracks 4 are sleeved on both sides of the wheels of the vehicle body 1. The terrain of sandy gravel soil is complex and changeable, including soft soil, hard rock, potholes, etc. The release device can utilize the flexibility and grip of the tracks 4 to adapt to these complex terrains, ensuring that the fertilizing device can fertilize smoothly.

[0023] In actual use, the driving device is connected through the connecting frame 5, and then the machine moves forward. The tilling plow 3 will plow the gravel soil, and at the same time, the fertilizer in the fertilizer barrel 2 will flow into the water distribution pipe 6, and the fertilizer in the water distribution pipe 6 will flow into the outflow pipe 11. The outflow pipe 11 will flow the fertilizer into the quantitative pipe 13 through the through hole 24. At this time, the bottom of the quantitative pipe 13 is supported by the blocking plate 15, and the blocking plate 15 is supported by the bottom plate 14. The blocking plate 15 will block the quantitative pipe 13, and the fertilizer will The fertilizer will accumulate inside the quantitative tube 13. When the fertilizer accumulates to the required amount, the telescopic motor 8 will start, and the transmission shaft of the telescopic motor 8 will generate a thrust on the transmission plate 9. The transmission plate 9 will generate a thrust on the force-bearing plate 18. The force-bearing plate 18 will drive the slide plate 19 to slide forward in the slide groove 21 provided inside the frame 10. The slide plate 19 sliding forward will make the through hole 24 no longer connected with the outflow pipe 11, and the outlet of the outflow pipe 11 will be blocked by the slide plate 19, so that the fertilizer will no longer flow out. The sliding plate 19 that slides forward drives the metering tube 13 to slide forward at the same time, and the metering tube 13 drives the blocking plate 15 to slide forward, and the blocking plate 15 will slide on the bottom plate 14, so that the blocking plate 15 will be separated from the extrusion of the bottom plate 14 during sliding, and the blocking plate 15 will leave from the outlet of the metering tube 13 due to the loss of extrusion force, so that the fertilizer accumulated in the metering tube 13 will fall into the soil just plowed by the tilling plow 3, and then the transmission shaft of the telescopic motor 8 will generate a pulling force on the transmission plate 9, so as to pull the sliding plate 19 back to its original position, so that the blocking plate 15 can continue to block the outlet of the metering tube 13 by the extrusion of the bottom plate 14, and the outflow pipe 11 can continue to accumulate the fertilizer in the metering tube 13 through the through hole 24, and repeat the cycle, so as to realize the quantitative fertilization of the soil, meet the actual needs of crops by controlling the amount of fertilizer applied, avoid waste and reduce the cost of fertilization, and at the same time, reduce nutrient loss and environmental pollution, and protect water resources and soil health.

[0024] Example 2

[0025] According to Example 1, when the slide plate 19 in Example 1 slides forward, the outflow pipe 11 will be blocked by the slide plate 19, and the fertilizer in the outflow pipe 11 will seep out from the outlet. Similarly, when the blocking plate 15 blocks the quantitative pipe 13, the fertilizer in the quantitative pipe 13 will also seep out from the outlet, thereby causing fertilizer flow loss and increasing fertilization costs. Figures 1-4, as another preferred embodiment of the present utility model, based on Embodiment 1, it further includes that a groove 20 is formed at the top of the sliding plate 19, and the inside of the groove 20 is in contact with the outflow pipe 11. By forming the groove 20, the outflow pipe 11 can slide inside the groove 20, creating a height difference between the outlet of the outflow pipe 11 and the sliding plate 19, thereby reducing the loss of fertilizer. A sealing ring 23 is fixedly installed at the top of the blocking plate 15, and the outside of the sealing ring 23 is in contact with the inside of the metering pipe 13. When the blocking plate 15 blocks the metering pipe 13, the sealing ring 23 will also be squeezed inside the metering pipe 13 to block the fertilizer. The sealing ring 23 is used to reduce the gap, thereby avoiding the loss of fertilizer. When the blocking plate 15 loses the extrusion force of the bottom plate 14, the fertilizer inside the metering pipe 13 can also offset the friction force of the sealing ring 23 being squeezed against the metering pipe 13 by its own weight, so as not to affect the normal opening of the blocking plate 15 from the outlet of the metering pipe 13. By reducing the loss of fertilizer, the agricultural cost is reduced.

[0026] Embodiment 3

[0027] According to Embodiment 1, when the blocking plate 15 slides on the bottom plate 14 in Embodiment 1, sliding friction will be generated, which is likely to produce noise and a sense of jerk. Referring to Figures 1-4 , as another preferred embodiment of the present utility model, based on Embodiment 1, it further includes that rollers 16 are rotatably arranged inside the bottom plate 14, and the rollers 16 are in contact with the bottom of the blocking plate 15. By arranging the rollers 16 inside the bottom plate 14, the blocking plate 15 can slide by the rolling of the rollers 16. This way of rolling contact greatly reduces the frictional resistance, making the sliding process quieter and smoother.

[0028] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, should be covered within the protection scope of the present utility model.
