[0027] Example 1

[0028] See Figures 1 to 6This utility model provides a ditching and fertilizing integrated machine with a fertilizer quantitative dispensing device, including a hand-held frame 1 with wheels, an engine 2 and a ditching mechanism 3 fixedly mounted on the frame 1, a transmission box 4 on the frame 1, the engine 2 drives the wheels and the ditching mechanism 3 through the transmission box 4, the transmission box 4 includes a rotating shaft 5 rotatably mounted on the frame 1, a driven pulley fixedly mounted on the rotating shaft 5, and a driving pulley fixedly mounted on the output shaft of the engine 2, the driving pulley and the driven pulley being connected by a transmission belt;

[0029] A drive sprocket is coaxially fixed on the shaft 5, an axle is set between the two wheels, a driven sprocket is fixed on the axle, and the drive sprocket and the driven sprocket are connected by a chain;

[0030] The frame 1 is also equipped with a fertilizer application mechanism 6, which includes a hopper 7 fixedly installed on the frame 1. A quantitative feeding unit 8 is installed at the lower end of the hopper 7. The quantitative feeding unit 8 is connected to the transmission box 4 through a power transmission unit 9.

[0031] A guide pipe is connected below the quantitative feeding unit 8, and the end of the guide pipe is located behind the trenching mechanism 3.

[0032] When the user starts the engine 2, the power of the engine 2 is transmitted through the drive pulley on the output shaft and the transmission belt 22 to the driven pulley on the shaft 5 of the transmission box 4, which drives the shaft 5 to rotate. When the shaft 5 rotates, the drive sprocket fixed on the same axis rotates accordingly, and the power is transmitted through the chain to the driven sprocket on the axle, thereby driving the wheels to rotate and enabling the device to move.

[0033] Simultaneously, power is transmitted from the transmission box 4 to the quantitative feeding unit 8 of the fertilization mechanism 6 via the power transmission unit 9. Driven by the power, the quantitative feeding unit 8 begins operation, and fertilizer in the hopper 7 enters the quantitative feeding unit 8 under gravity. The quantitative feeding unit 8 removes the fertilizer according to the set amount, and then the fertilizer falls through the guide pipe into the pre-dug trench behind the trenching mechanism 3, completing the fertilization process. Throughout the entire operation, the integrated machine moves while simultaneously trenching and fertilizing, achieving continuous operation.

[0034] The quantitative feeding unit 8 includes a housing 10 fixedly mounted on the hopper 7, a turntable 11 rotatably mounted inside the housing 10, and a plurality of material troughs 12 arrayed on the outer wall of the turntable 11.

[0035] When the fertilizer quantitative feeding unit 8 is working, the power transmission unit 9 transmits power to the turntable 11 of the quantitative feeding unit 8, causing it to rotate inside the outer shell 10. Under the action of gravity, the fertilizer in the hopper 7 falls into the feed trough 12 of the turntable 11. As the turntable 11 rotates, when the feed trough 12 containing fertilizer rotates to a specific position, due to the action of gravity, the fertilizer in the feed trough 12 will fall into the guide pipe connected below, and then be transported to the ditch behind the ditching mechanism 3. The turntable 11 continues to rotate, and the feed trough 12 continuously repeats the loading and unloading process, thereby realizing the quantitative application of fertilizer.

[0036] A baffle 13 is slidably installed in each trough 12. A screw 14 is fixedly installed on the side of each baffle 13 facing the center of the turntable 11. A driven bevel gear 15 is threadedly connected to the screw 14. The driven bevel gear 15 is rotatably mounted on the turntable 11.

[0037] A drive bevel gear 16 is also rotatably mounted on the turntable 11, and the drive bevel gear 16 meshes with a plurality of driven bevel gears 15 respectively.

[0038] Before the device is put into operation, the position of the baffle 13 in the feed trough 12 can be adjusted according to the fertilizer application requirements. The drive bevel gear 16 is rotated, which drives the multiple driven bevel gears 15 that mesh with it to rotate. Since the driven bevel gears 15 are threadedly connected to the screw 14, as the driven bevel gears 15 rotate, the screw 14 will drive the baffle 13 to move radially in the feed trough 12. Once the position of the baffle 13 is adjusted, the device can be started.

[0039] By adjusting the position of the baffle 13 within the feed trough 12, the effective volume of the feed trough 12 can be flexibly changed, thereby precisely controlling the amount of fertilizer applied each time. This adjustable design can adapt to the diverse needs of different crop types, different growth stages, and different soil fertility conditions for fertilizer application, greatly improving the accuracy of fertilization, which is conducive to achieving precision agriculture fertilization, improving fertilizer utilization, and reducing fertilizer waste and environmental pollution.

[0040] Two knobs 17 are rotatably mounted on the drive bevel gear 16, and each knob 17 is threadedly connected to a slider 18.

[0041] An annular groove 19 is fixedly provided on the turntable 11, and the slider 18 slides within the groove 19.

[0042] When it is necessary to adjust the fertilizer application rate, i.e., change the position of the baffle 13 in the feed trough 12, the operator first loosens the knob 17, allowing the slider 18 to move freely within the annular groove 19. Then, according to the required fertilizer application rate, one of the knobs 17 is slowly rotated, causing the slider 18, which is threaded to it, to move within the groove 19. Since the knob 17 is connected to the driving bevel gear 16, its movement will cause the driving bevel gear 16 to rotate. The rotation of the driving bevel gear 16 will then drive the multiple driven bevel gears 15 meshing with it to rotate synchronously, thereby driving the screw 14 to rotate, so that the baffle 13 moves radially within the feed trough 12.

[0043] During the movement of the baffle 13, the operator can determine the change in the effective volume of the trough 12 by observation or measuring tools, thereby precisely controlling the adjustment range of the fertilizer application rate. When the expected fertilizer application rate adjustment target is reached, stop turning the knob 17 and tighten the knob 17 to fix the slider 18 in the slide 19. The active bevel gear 16 and the entire baffle 13 adjustment mechanism will remain stably in the current state and will not easily change position due to vibration or other external forces during equipment operation.

[0044] In this way, during the subsequent trenching and fertilization operations, it can be ensured that the fertilizer metering device always operates according to the set precise fertilizer amount, providing a stable and reliable fertilization guarantee for the healthy growth of crops, while also helping to improve fertilizer utilization and reduce waste and potential environmental pollution.

[0045] The power transmission unit 9 includes an output pulley 20 fixedly mounted on one side of the turntable 11, and an input pulley 21 coaxially fixedly mounted on the rotating shaft 5. The input pulley 21 and the output pulley 20 are connected by a transmission belt 22.

[0046] When engine 2 is started, the power output of engine 2 is transmitted through the drive pulley fixed on its output shaft to the driven pulley on the drive belt 22, causing the drive shaft 5 to start rotating. As the drive shaft 5 rotates, it drives the input pulley 21 to rotate synchronously, which in turn drives the output pulley 20 connected to it to rotate, thereby realizing the rotation of turntable 11. The fertilizer is unloaded into the guide pipe connected below, so that the fertilizer can be transported to the ditch behind the ditching mechanism 3, completing the quantitative delivery of fertilizer in the entire fertilization process.

[0047] When using this utility model, the user starts the engine 2. The power of the engine 2 is transmitted through the drive pulley on the output shaft and the transmission belt 22 to the driven pulley on the rotating shaft 5 of the transmission box 4, which drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, the drive sprocket fixed on the same axis rotates accordingly. The power is transmitted through the chain to the driven sprocket on the axle, thereby driving the wheels to rotate and enabling the device to move.

[0048] Simultaneously, power is transmitted from the transmission box 4 to the quantitative feeding unit 8 of the fertilization mechanism 6 via the power transmission unit 9. Driven by the power, the quantitative feeding unit 8 begins operation, and fertilizer in the hopper 7 enters the quantitative feeding unit 8 under gravity. The quantitative feeding unit 8 removes the fertilizer according to the set amount, and then the fertilizer falls through the guide pipe into the pre-dug trench behind the trenching mechanism 3, completing the fertilization process. Throughout the entire operation, the integrated machine moves while simultaneously trenching and fertilizing, achieving continuous operation.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
