[0015] 2) The first soil turning and initial fertilization of the soil breaking wheel: The soil breaking wheel rotates and inserts into the ground to initially turn the ground. During the soil turning process of the soil breaking wheel, the fertilizer enters the soil retaining cover from the feed trough through the first lower material cover, and then falls down from the first material cavity of the soil retaining cover to the ground or the soil breaking wheel. The soil breaking wheel crushes the fertilizer that falls on it and drives the crushed fertilizer into the soil. At the same time of turning the soil, the fertilizer and soil are mixed, thus completing the soil turning, fertilizer crushing and fertilization before and during soil turning;

[0016] 3) Secondary tillage and secondary fertilization by the tilling knife: While step 2) is being carried out, the tilling knife is inserted into the soil and performs secondary tillage and crushing of the soil after the initial tillage at the rear side. During this process, the fertilizer in the feed trough enters the second material chamber through the second lower material cover and is sprinkled from the second material chamber onto the second tilled soil. Afterwards, the knife rake mixes and levels the fertilizer and soil again.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. By arranging a feed trough, a soil-breaking blade wheel, a soil-turning blade, a first lower material cover, a second lower material cover and a soil retaining cover, when turning the soil, the soil-breaking blade wheel first turns the soil for the first time, and in this process, fertilizer enters the soil retaining cover from the feed trough through the first lower material cover, and is scattered from the soil retaining cover to the ground or the soil-breaking blade wheel, completing the first soil turning and fertilization of the land, and the soil retaining cover can be used to fertilize before and during the soil turning by the soil-turning blade wheel, thereby improving the effect of fertilizer infiltration into the soil and improving fertilizer efficiency; after that, turning the soil The soil knife continues to turn the soil for the second time, and in this process, the fertilizer enters the second material chamber of the soil turning knife from the feed trough through the second lower material cover, and is sprinkled into the soil from the second material chamber, completing the secondary turning and fertilizing of the land. Afterwards, the knife rake scrapes the soil flat and mixes the soil and fertilizer. The whole device combines the turning function and the fertilizing function together, and simultaneously completes the multi-step operations of turning the soil and fertilizing, with high efficiency, saving labor costs and machine costs, and the overall setting structure is compact and the combination and mixing are clever.

[0019] In addition, the setting of the soil-breaking wheel can be used for turning the soil, crushing the fallen fertilizer, bringing the fertilizer down into the soil to facilitate burying the fertilizer deeply in the soil, and mixing the soil and fertilizer during the rotation; as for the soil retaining cover, it can cover the soil-breaking wheel on the upper side to prevent the soil from flying outward, and be used as a fertilization tool to fertilize the soil, and can scrape off large pieces of mud or entangled plants stuck on the soil-breaking wheel; as for the soil-turning knife, it can be used to turn the soil and act as a fertilization tool for fertilization. Each component can achieve multiple functions and effects through mutual cooperation, and has high functionality.

[0020] 2. By arranging a stirring device in the feed trough, the fertilizer in the feed trough can be stirred and mixed, and the feed trough can be prevented from being blocked.

[0021] 3. By arranging a toggle plate in the second material chamber, the toggle plate is connected to the push plate through an extending rod, movable holes are arranged on the left and right side walls of the second material chamber, a telescopic corrugated cover is arranged on the movable hole, and an outer push plate that can extend the telescopic corrugated cover is arranged on the left and right sides of the toggle plate. When the tilling knife moves forward in the soil to turn the soil, the turned soil moves backward, and the backward soil and the fixed soil on both sides of the tilling knife have a backward resistance thrust on the outer push plate, and the resistance thereby pushes the outer push plate backward. When the outer push plate is pushed backward, it will drive the toggle plate to move backward. After the toggle plate moves backward, it will drive the push plate backward, and then the push plate will push the fertilizer backward, so that the fertilizer can flow out of the second feed hole more smoothly, thereby improving the flow smoothness of the fertilizer.

[0022] 4. By arranging a slide rail in the second material cavity, the toggle plate is slidably connected to the slide rail, which provides a guide for the moving direction of the toggle plate to prevent the toggle plate from deflecting.

[0023] 5. By arranging a plurality of second sharp knives on the inner wall of the second material cavity, the fertilizer falling into the second material cavity can be crushed.

[0024] 6. By setting a beating bar at the bottom of the material retaining cover, the earth-breaking knife wheel can be thrown away to reduce the accumulation of mud on the earth-breaking knife wheel.

[0025] 7. By arranging the first valve and the second valve in the feed trough, the opening and closing of the first feed cover and the second feed cover can be controlled according to actual conditions.

[0026] 8. By using a fruit and vegetable planting soil turning and fertilizing device to perform soil turning and fertilizing, multiple soil turning and multiple fertilization can be completed simultaneously, the initial fertilization is completed before the soil breaking knife wheel turns the soil for the first time, the second fertilization is completed during the soil turning process of the soil breaking knife wheel, and the third fertilization is performed when the soil turning knife turns the soil for the second time. In the process of turning the soil, multiple steps of fertilization operations are completed, the fertilizer efficiency is improved, the overall efficiency is high, and labor costs can be saved.
