The top of the fertilizer baffle 5 abuts against the top wall of the mounting shell 2. A flow control slot hole 6 is provided on the flow control plate 4. The flow control slot hole 6 is connected to the fertilizer hole 3. The width of the flow control slot hole 6 gradually increases, and the tapered slot hole The end with a larger hole width is equal to the width of the fertilizer hole 3, and the end with a smaller tapered slot hole width is smaller than the width of the fertilizer hole 3. The height of the upper side surface of the flow control plate 4 is set to be an arc surface that gradually decreases toward the edge of the flow control slot hole 6. A flow control motor 7 is fixed on the installation shell 2, and a driving screw 8 is connected to the front end of the flow control motor 7. A transmission nut 9 is fixed on the side wall of the flow control plate 4, and the transmission nut 9 is threadedly connected to the driving screw 8. A limited slide rail is installed on the installation shell 2, and a slider is fixed on the flow control plate 4. The slider is slidably matched and connected to the limited slide rail;

[0030] like Figure 3-4 As shown, the interval fertilization device includes a rotating drum 10, the rotating drum is eccentrically provided with a fertilizer guide hole 11, the fertilizer guide hole 11 is connected to the fertilizer hole 3, a rotating shaft is provided at the center of the rotating drum 10, the rotating shaft is fixed on the frame, a gear ring 12 is sleeved on the side wall of the rotating drum 10, an interval adjustment mechanism is connected to the rotating drum 10, and the interval speed regulation mechanism includes a speed regulating motor 13, a speed regulating friction wheel 14, a speed regulating cylinder 15, a transmission friction wheel 16, a transmission rod 17 and a half gear 18, the speed regulating motor 13 and the speed regulating cylinder 15 are fixed on the frame, the speed regulating friction wheel 14 is fixedly connected to the speed regulating motor 13, the cylinder arm of the speed regulating cylinder 15 is connected with a sliding sleeve 19, the sliding sleeve 19 is sleeved on the rotating transmission rod 17, and the sliding sleeve 19 is rotatably connected to the rotating transmission rod 17. On the transmission friction wheel 16, a rotating bearing is connected between the sliding sleeve 19 and the transmission friction wheel 16, the sliding sleeve 19 is fixed on the inner ring of the transmission bearing, and the transmission friction wheel 16 is fixed on the outer ring of the rotating bearing. The speed regulating friction wheel 14 and the transmission friction wheel 16 are in vertical contact with each other, that is, the circumferential side wall of the transmission friction wheel 16 is in contact with the side of the speed regulating friction wheel 14, the transmission rod 17 is rotatably arranged on the frame, the transmission friction wheel 16 is slidingly sleeved on the transmission rod 17, a vertically opened limiting groove is arranged on the outer wall of the transmission rod 17, a limiting block is arranged on the inner wall of the transmission friction wheel 16, and the limiting block is slidingly inserted in the limiting groove, the half gear 18 is interference-fittedly sleeved on the transmission rod 17, and the half gear 18 is meshed with the gear ring 12.

[0031] In summary, in the utility model, the fertilizer is stored in the hopper 1, and enters the installation shell 2 from the hopper 1 downward through the fertilizer hole 3. Due to the restriction of the fertilizer baffle 5 around the flow control plate 4, the fertilizer can only flow onto the flow control plate 4. Since the upper side of the flow control plate 4 is set as an arc surface, the fertilizer will slide along the arc surface into the flow control slot hole 6 and will not be retained. The flow control slot hole 6 slides left and right under the action of the flow control motor 7, so as to change the connection area between the flow control slot hole 6 and the fertilizer hole 3 on the lower side of the installation shell 2, so as to adjust the flow rate of the fertilizer. The fertilizer flows to the position of the interval adjustment mechanism. Due to the rotation of the rotating cylinder 10, the fertilizer guide hole 11 is intermittently connected with the fertilizer hole 3, and the fertilizer is also intermittently sprinkled. This intermittent time is adjusted according to the planting interval of crops. The adjustment of the intermittent time can be completed by extending and retracting the speed regulating cylinder 15. The cylinder 15 contracts and pulls the transmission friction wheel 16 to lift on the transmission rod 17 through the sliding sleeve 19, that is, the transmission friction wheel 16 is lifted on the speed regulating friction wheel 14, and the contact position between the transmission friction wheel 16 and the speed regulating friction wheel 14 is closer to the rotating circle of the speed regulating friction wheel 14, that is, the circumferential speed of the contact position is reduced, and then the rotation speed of the transmission rod 17 is reduced, thereby reducing the rotation speed of the rotating drum 10. In this process, the time interval for the fertilizer guide hole 11 to be connected with the fertilizer hole 3 is increased, but the connection time is also increased. At this time, in order to keep the amount of fertilizer unchanged, the connection area between the flow control slot hole 6 and the fertilizer hole 3 can be appropriately increased to keep the amount of fertilizer unchanged. In summary, the flow control device and the interval fertilization device can be used in combination to meet different fertilization environments with different crop spacing and fertilizer application requirements.
