Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0016] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0017] Example 1

[0018] See also Figures 1 to 4As shown, the present embodiment involves a fertilizer spreading device for improving soil fertility, comprising a storage container 1 and a spreader 2, the spreader 2 and the storage container 1 being connected in series via a feed hose 3, the spreader 2 comprising a spreading shell 201 having an axis extending up and down and in the shape of a cylindrical shell, a spreading port 202 being provided on the side of the spreading shell 201, a spreading disc 203 coaxially arranged therewith being rotatably connected in the spreading shell 201, a plurality of retaining strips 204 extending radially are arranged around the top of the spreading disc 203, a feed port 205 is provided on the top of the spreading shell 201 for connecting its interior with the interior of the feed hose, a feed baffle 206 is provided on the feed port 205, a fixed port 207 extending circumferentially is provided on the feed baffle 206, The shutter 208 for opening and closing the fixed opening has a tail plate 209 at the other end, and a limiting hole 210 extending along the circumferential direction is provided on the tail plate 209. A fixed limiting post 211 fixedly connected to the shutter is slidably connected in the limiting hole 210, and one end of the limiting hole 210 is provided with a movable limiting post 212 provided on the tail plate. An elastic member (not shown) is connected between the movable limiting post 212 and the fixed limiting post 211. The elastic member is a tension spring that is sleeved on the fixed limiting post at one end and sleeved on the movable limiting post at the other end. The bottom of the shutter 208 is provided with a protrusion 213 extending between the two adjacent stop strips, and the stop strip 204 is provided with a process notch 214 for the protrusion to pass through, and a spring piece 215 that is integrated with the stop strip and for blocking the protrusion is provided in the process notch 214.

[0019] Furthermore, a hood 216 is provided on the top of the sowing housing 201, and a motor (not shown) fixedly connected to the sowing housing is provided inside the hood 216, and the output shaft of the motor is transmission-connected to the sowing disc 203, and a power supply (not shown) for powering the motor is provided inside the hood 216, and a switch 217 for controlling the power on and off is provided outside the hood 216.

[0020] Furthermore, the interval angles between two adjacent blocking strips 204 are equal.

[0021] In this embodiment, due to the elastic force of the elastic member (i.e., the tension spring), the fixed limiting post 211 and the movable limiting post 212 are tightened, so that the shutter 208 in the natural state closes the fixed opening 207, and the fertilizer particles in the storage container 1 cannot flow into the spreader 2 along the feeding hose 3. By operating the switch 217, the motor drives the sowing disc 203 to rotate. During the rotation of the sowing disc 203, the spring piece 215 on the upper material blocking strip 204 thereof will move the protrusion 213, causing the protrusion 213 to rotate with the shutter 208, and realize opening the fixed opening 207, so that the fertilizer particles concentrated at the pipe opening flow to the sowing disc 203 of the spreader 2. Because the sowing disc 203 continues to rotate, when the shutter 208 is fully opened, the protrusion 213 can no longer As the shield 208 rotates, the rotating spreading disc 203 deforms the spring plate 215 on it until the protrusion 213 passes the spring plate 215. When the protrusion 213 is no longer rotating, the protrusion 213, under the restoring force of the elastic member, quickly drives the shield 208 to close the fixed opening 207 again until the next spring plate 215 moves the protrusion 213. This cycle continues, achieving the effect of intermittent feeding above the spreading disc 203. With the centrifugal motion of the spreading disc 203 within the spreading housing 201, the fertilizer particles supplied to the top of the spreading disc 203 are thrown out from the side spreading opening 202 for fertilizer dissemination.
