[0002] Hawthorn trees are a common economic crop in Shandong, Henan, Hebei and other places in China. Hawthorn is a shallow-rooted tree species with strong growth ability and can grow on barren mountains. Moreover, hawthorn fruits can be both eaten and used medicinally, so it has high popularization and planting value; although hawthorn trees are drought-tolerant and barren-tolerant, in order to promote the growth of plants and increase fruit yield, it is necessary to spray liquid fertilizer on the leaves of plants irregularly after the planting of hawthorn saplings, during the growth period of plants and during the flowering period to achieve the purpose of rapid topdressing and promoting growth.

[0003] The utility model patent with the patent number "CN 217160446 U" discloses a fertilizing device for hawthorn planting, which solves the problem that the direction and height of the nozzle cannot be adjusted during the fertilizer spraying process and improves the fertilizing efficiency to a certain extent. However, the mechanism components for adjusting the height and direction of the nozzle on the device are all exposed, and the liquid fertilizer sprayed by the nozzle is easily adhered to these mechanism components, which is likely to cause rust over time and seriously affect the service life of the device.

[0004] Therefore, it is necessary to propose a fertilizing device for hawthorn planting to reduce the probability of contact between the liquid fertilizer sprayed by the nozzle and the mechanism components and extend the service life of the device. Summary of the Utility Model

[0006] The technical solution of the utility model is as follows:

[0007] A fertilizing device for hawthorn planting includes a frame. The frame is rotatably connected with a turntable. The frame is provided with a first driving device, and the first driving device drives the turntable to rotate. A support seat is fixedly connected to the top of the turntable. A shaft hole is provided in the support seat. A lead screw is arranged in the shaft hole. A nut is sleeved on the lead screw. A protective shell is fixedly connected to the top of the support seat. The lead screw and the nut are located inside the protective shell. A groove is provided on one side of the protective shell. A slide rail is provided on the side wall of the groove. A slider is slidably connected to the slide rail. A nozzle is provided on the slider. The slider is fixedly connected to the nut. The lead screw is connected with a second driving device, and the second driving device drives the lead screw to rotate and then drives the slider to slide in the groove.

[0008] Furthermore, the frame is provided with a first fixing hole, and the first driving device is fixedly arranged in the first fixing hole.

[0009] Further, the first driving device is a motor, and a gear is connected to the output end of the first driving device. An internal gear ring is fixedly connected to the bottom of the turntable, and the internal gear ring is in meshing transmission with the gear.

[0010] Further, the frame is provided with a second fixing hole, and the bottom of the turntable is located in the second fixing hole. A bearing is provided in the second fixing hole, and the turntable is rotatably connected to the frame through the bearing.

[0011] Further, a speed reducer is connected to the output end of the second driving device, and the output end of the speed reducer is fixedly connected to the lead screw.

[0012] Further, the second driving device is a motor, and the second driving device is located between the turntable and the support seat and is fixedly connected to the turntable.

[0013] Further, a medicine cylinder is provided on the frame, a pressure pump is installed at the top of the medicine cylinder, the pressure pump is connected with a medicine pipe, and the medicine pipe is communicated with a nozzle.

[0014] Further, a handrail is provided at one end of the frame, and a controller is installed at the top of the handrail. The controller controls the start-stop and operating power of the first driving device and the second driving device.

[0015] For a fertilizer application device for hawthorn planting according to the present utility model, driven by the first driving device, the turntable can rotate the turntable and the support seat on the turntable. When the support seat rotates, the lead screw, nut and nozzle on it will rotate synchronously, so as to realize the adjustment of the nozzle angle. And the second driving device can drive the lead screw to rotate so as to drive the slider to lift, and finally realize the height adjustment of the nozzle. Since a protective shell is fixedly connected to the support seat, and the lead screw and nut are both located in the protective shell. When the nozzle sprays liquid fertilizer, the protective shell can block the liquid fertilizer from falling into the lead screw and nut, thereby playing a protective role for components such as the lead screw and nut. Compared with the traditional technology, this technical solution sets a protective shell on the support seat, which plays a protective role for components such as the lead screw and nut, reduces the probability of the liquid fertilizer sprayed by the nozzle contacting the mechanism components, and prolongs the service life of the equipment.

The stepping motor drives the gear 15 to rotate, and the gear 15 drives the internal gear ring 16 to rotate, so as to realize the rotation of the turntable 2 and the adjustment of the angle of the nozzle 12. Preferably, the frame 1 is provided with a second fixing hole 17, the bottom of the turntable 2 is located in the second fixing hole 17, a bearing is arranged in the second fixing hole 17, and the turntable 2 is rotatably connected with the frame 1 through the bearing.

The turntable 2 rotates under the drive of the first driving device 3, driving the support base 4 on the turntable 2 to rotate. When the support base 4 rotates, the lead screw 6, the nut 7, the second driving device 13 and the nozzle 12 thereon will rotate synchronously, thereby realizing the adjustment of the angle of the nozzle 12. When it is necessary to adjust the height of the nozzle 12, the corresponding switch button on the controller 23 is adjusted. The second driving device 13 is started and drives the lead screw 6 to rotate, thereby driving the slider 11 to lift. The slider 11 slides in the groove 9. Since the slider 11 is fixedly connected to the nozzle 12, the height of the nozzle 12 can be adjusted. Since a protective shell 8 is fixedly connected to the support base 4, the lead screw 6 and the nut 7 are both located inside the protective shell 8, and only the nozzle 12 and part of the slider 11 are exposed outside the protective shell 8. When the nozzle 12 sprays liquid fertilizer, the protective shell 8 can block the liquid fertilizer from falling into the lead screw 6 and the nut 7, thereby playing a protective role for components and mechanisms such as the lead screw 6 and the nut 7. Compared with the traditional technology, in this technical solution, by providing the protective shell 8 on the support base 4, it plays a protective role for components and mechanisms such as the lead screw 6 and the nut 7, reduces the probability of the liquid fertilizer sprayed by the nozzle 12 contacting the mechanism components, and extends the service life of the equipment.
