[0051] Combination Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown in the content, the fertilizer application mechanism 2 is fixedly mounted on the main frame 11 of the mobile vehicle frame 1. The fertilizer application mechanism 2 includes a storage box 21 fixedly mounted above the main frame 11 of the mobile vehicle frame 1, a feeding unit 22 located below the storage box 21, and a feeding unit 23 located on the left and / or right side of the main frame 11 of the mobile vehicle frame 1. (See reference) Figure 6 and Figure 7 As shown, the storage box 21 is provided with a storage cavity with a "U" shaped cross-section and a discharge port 211 connected to the storage cavity. The discharge unit 22 is connected to the storage cavity through the discharge port 211, and the feeding unit 23 is connected to the discharge unit 22 through a conveying pipe (not shown in the figure).

[0052] like Figure 5 and Figure 7 As shown, the feeding unit 22 includes a distributing box 221 fixedly installed at the feeding port 211 below the storage box 21, a distributing wheel 222 rotatably installed inside the distributing box 221, and a distributing drive assembly connected to the distributing wheel 222. The bottom of the distributing box 221 has a discharge port to transport fertilizer through the discharge port and the connected conveying pipe to the application unit 23 for spreading and fertilization. The distributing wheel 222 has several circumferentially spaced teeth. For details, refer to...

The material distribution controller can change the amount of fertilizer applied at the bottom outlet of the material distribution box 221 by controlling the operating state of the material distribution motor 224, thereby achieving precise adjustment and control of the amount of fertilizer applied.

[0053] Combination Figure 1 and Figure 2As shown in the contents, the material application unit 23 includes a landing gear 231 connected to the main frame 11 of the mobile frame 1, and a material spreading terminal 232 connected to the landing gear 231. The landing gear 231 includes an upper crossbar 2311 and a lower crossbar 2312 that are movably hinged to the main frame 11 of the mobile frame 1, and a vertical support bar 2313 that is movably hinged to the upper crossbar 2311. One end of the upper crossbar 2311 is movably hinged to the main frame 11, and the other end is movably hinged to the vertical support bar 2313. One end of the lower crossbar 2312 is movably hinged to the main frame 11, and the other end is movably hinged to the material spreading terminal 232. The material spreading terminal 232 is also connected to the end of the vertical support bar 2313.

[0054] The upper crossbar 2311 is equipped with a control lever 2314 fixedly connected thereto. The control lever 2314 is equipped with a lifting frame 2315 movably connected thereto. The end of the lifting frame 2315 is equipped with a locking groove. The main frame 11 of the mobile frame 1 is equipped with a locking post that matches the locking groove. When the locking groove of the lifting frame 2315 is engaged with the locking post, the control lever 2314 is in a downward pressing state. At the same time, the upper crossbar 2311 drives the vertical support 2313 to lift upward, thereby lifting the spreading terminal 232 so that the spreading terminal 232 is detached from the soil surface. This is the non-fertilizing working state. When fertilizing is required, simply pull the lifting frame 2315 to detach it from the locking post. At this time, the spreading terminal 232 contacts the soil surface to perform spreading and fertilizing work.

[0055] refer to Figure 2 and Figure 3As shown in the description, the vertical support rod 2313 has a guide sleeve 2316 at its end, and the guide sleeve 2316 has a limiting groove 23161 that penetrates its side wall. The material spreading terminal 232 includes a leg support body 2324, an upper shell cover 2325 fixedly connected to the leg support body 2324, and material spreading discs 2326 symmetrically arranged on both sides of the leg support body 2324. The guide sleeve 2316 of the vertical support rod 2313 is sleeved on the outer periphery of the top end of the leg support body 2324. The bottom end of the leg support body 2324 has an inner rotating shaft 23242 and an outer rotating shaft 23243 symmetrically distributed. The material spreading discs 2326 are rotatably sleeved on the outer periphery of the inner rotating shaft 23242 and the outer rotating shaft 23243. The upper shell cover 2325 has an inlet located between the two material spreading discs 2326. 23251, for spreading fertilizer transported through the conveying pipe, the end of the lower crossbar 2312 is movably hinged to the leg support 2324; the top of the leg support 2324 is provided with a limiting block 23241 adapted to the limiting groove 23161, the limiting block 23241 is movably embedded in the limiting groove 23161 to limit the suspension movement of the leg support 2324; the spreading terminal 232 also includes a floating spring 2327 disposed between the bottom of the guide sleeve 2316 at the end of the vertical support 2313 and the upper shell 2325, the two ends of the floating spring 2327 respectively abut against the guide sleeve 2316 and the upper shell 2325 of the vertical support 2313, so that the spreading disc 2326 is in contact with the soil surface during the fertilization spreading process.

[0056] Further reference Figure 3 As shown, the inner rotating shaft 23242 and the outer rotating shaft 23243 are arranged in parallel, and the angle between the plane where they are located and the horizontal plane is between 90° and 180°. The angle between the inner rotating shaft 23242 and the outer rotating shaft 23243 is less than 180°, so that the spreading discs 2326 on both sides have an opening shape that narrows in front and widens in the back, which facilitates fertilization and spreading when plowed into the soil. The upper shell 2325 is provided with a scraper 2328 fixedly connected to it. The scraper 2328 contacts the surface of the spreading disc 2326 to scrape off the soil adhering to the surface of the spreading disc 2326.

[0057] like Figure 4 and Figure 6 As shown, the spraying mechanism 3 is fixedly mounted on the main frame 11 of the mobile vehicle frame 1 and located behind the fertilizer application mechanism 2.

[0058] refer to Figure 8 As shown, the main frame 11 of the mobile vehicle frame 1 is equipped with a height adjustment disc 13 fixedly connected to it. The height adjustment disc 13 has an arc-shaped piece 131 located on its outer edge, and the arc-shaped piece 131 has several adjustment holes 132 spaced apart along the circumferential direction. The spray frame 33 is rotatably connected to the height adjustment disc 13 via a rotating shaft. The rotating shaft and the height adjustment disc 13 are coaxially arranged. The spray frame 33 is equipped with a locking seat 331 located outside the arc-shaped piece 131 and a plug 332 adapted to the adjustment holes 132. The plug 332 is movably inserted into the locking seat 331 so that the plug 332 can be inserted into the adjustment hole 132 for locking, or the plug 332 can be pulled out of the adjustment hole 132 to release the locking state, so that the spray frame 33 can rotate automatically, thereby achieving the function of adjusting the height position of the spray frame 33.

[0059] Furthermore, the locking seat 331 is provided with a locking plate 3311, and the insert rod 332 is provided with a cam plate 3321 and a locking spring 3322 that abuts against the cam plate 3321. The other end of the locking spring 3322 abuts against the side of the locking seat 331 away from the height adjustment disc 13. By rotating the insert rod 332, the cam plate 3321 and the locking plate 3311 are misaligned and no longer abut against each other. Under the action of the locking spring 3322, the insert rod 332 is inserted into the adjustment hole 132. To prevent the insertion rod 332 from automatically disengaging from the adjustment hole 132, when the height of the spray frame 33 needs to be adjusted, simply pull the insertion rod 332 upwards. At this time, the locking spring 3322 is compressed. After pulling a certain distance, the insertion rod 332 is rotated so that the cam plate 3321 and the retaining plate 3311 alternately abut against each other. The insertion rod 332 is relatively fixed and remains disengaged from the adjustment hole. After the height of the spray frame 33 is adjusted, the above locking steps are repeated to lock the height of the spray frame 33.

[0060] Combination Figure 1 , Figure 4 and Figure 6 As shown in the description, the spray frame 33 includes a main frame 333 and an extension rod 334 that is movably hinged to the main frame 333. The main frame 333 is in the shape of a "∏" and its bottom ends are rotatably connected to the height adjustment discs 13 on both sides. The extension rod 334 is symmetrically arranged on both sides of the main frame 333 and the hinge axis is located at the top of the main frame 333. The extension rod 334 is provided with at least two branch rods 3341 that are hinged end to end to increase the spraying area. At the same time, the extension rod 334 can be stored after the spraying work is completed, improving the overall accessibility and placement convenience.

[0061] Furthermore, the integrated fertilization and pesticide application device provided in this embodiment also includes a power mechanism, which is fixedly mounted on the main frame 11 of the mobile frame 1. The power mechanism includes a power source connected to the mobile wheels 12, the fertilization mechanism 2, and the pesticide application mechanism 3. It should be noted that the power source can be a power battery or fuel gas. Given that these are mature existing technologies, their structure and principle will not be described in detail here, nor will they be shown in the figure.
