DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] The present application embodiment provides a fertilizer applicator with adjustable fertilizer application amount, such as Figure 1-Figure 5 As shown, it includes a storage barrel 1, a receiving plate 4, a rotating mechanism 5, etc.

[0026] Specifically, a feeding port 101 is provided on one side of the material storage barrel 1, and the outer side of the feeding port 101 is connected to a feeding hopper 2. A circular baffle 3 is provided in the material storage barrel 1, and a first arc-shaped notch 301 is provided on the circular baffle 3; the accommodating disk 4 is rotatably connected to the material storage barrel 1, and is arranged below the circular baffle 3, and its diameter matches the inner diameter of the material storage barrel 1, and a plurality of second arc-shaped notches 401 matching the first arc-shaped notch 301 are provided downward in a circular array on the top of the accommodating disk 4, and the bottom surfaces of the second arc-shaped notches 401 are all inclined downward, and the height of the bottom surface of each second arc-shaped notch 401 is different. When the second arc-shaped notch 401 rotates to face the feeding port 101, the second arc-shaped notch 401 is within the coverage range of the feeding port 101; the rotating mechanism 5 is provided at the bottom of the material storage barrel 1, which is connected to the accommodating disk 4, and is used to drive the accommodating disk 4 to rotate.

[0027] In actual use, fertilizer is loaded into the storage barrel 1, and then the receiving disk 4 is rotated by the rotating mechanism 5. When the second arc-shaped notch 401 of the receiving disk 4 is rotated to below the first arc-shaped notch 301 of the circular baffle 3, the fertilizer will fall into the second arc-shaped notch 401, and then the second arc-shaped notch 401 is rotated to face the discharge port 101, and the fertilizer therein will slide into the discharge hopper 2 along the inclined surface at its bottom, and then fall into the soil, realizing one-time quantitative fertilization, and then the receiving disk 4 is rotated back by the rotating mechanism 5, so that the second arc-shaped notch 401 is rotated again to below the first arc-shaped notch 301, and the above steps are repeated to realize multiple fertilizations. When the amount of fertilizer applied at a time needs to be adjusted, the other second arc-shaped notches 401 can be rotated to below the first arc-shaped notches 301 so that fertilizer can fall into them. Because the bottom height of the second second arc-shaped notches 401 is different from the bottom height of the other first arc-shaped notches 301, the amount of fertilizer contained therein is different. By rotating the second second arc-shaped notches 401 toward the discharge port 101, the fertilizer can be discharged for a single fertilization, thereby achieving the adjustment of the amount of fertilizer applied.

[0028] For details, see Figure 1The storage barrel 1 is connected to a fixed frame 6, and two pairs of rollers 601 are provided at the bottom of the fixed frame 6. When applying fertilizer, the fixed frame 6 can be pushed, and the fixed frame 6 is driven to move by the rollers 601, so that the fertilizer applicator does not need to be lifted for a long time for fertilization. More specifically, a U-shaped push rod 602 is provided on the side of the fixed frame 6 away from the lower hopper 2, which is used to push the fixed frame 6 to move, thereby improving the convenience of fertilization.

[0029] For details, see Figure 1 , Figure 2 , Figure 5 The rotating mechanism 5 includes a connecting column 501, a ring gear 502, a rack 503, and a cylinder 504. The connecting column 501 is coaxially connected to the bottom of the accommodating plate 4. The bottom of the connecting column 501 extends out of the storage barrel 1 and is connected to the ring gear 502. The ring gear 502 is meshed and connected to the rack 503. The rack 503 is connected to the telescopic end of the cylinder 504. The telescopic direction of the telescopic end of the cylinder 504 is parallel to the length direction of the rack 503. The cylinder 504 is fixed outside the storage barrel 1. During actual installation, the initial state of the receiving plate 4 is that the second arc-shaped notch 401 to be used is below the first arc-shaped notch 301. When fertilizer is needed, the telescopic end of the cylinder 504 is pushed out, and the gear ring 502 and the receiving plate 4 are driven to rotate through the rack 503, so that the second arc-shaped notch 401 to be used can be rotated to face the discharge port 101, and the fertilizer is discharged into the discharge hopper 2. When fertilizer needs to be filled in the second arc-shaped notch 401, the telescopic end of the cylinder 504 is controlled to retract. For more details, refer to Figure 5 The rack 503 is slidably connected in a slide rail 505, and the slide rail 505 is connected to the storage barrel 1 through a connecting block 506. The rack 503 can only slide in the slide rail 505, which can improve the stability of the rack 503 during sliding and prevent it from deflecting.

[0030] Preferably, see Figure 2 , Figure 5 , a threaded hole is provided on one side of the connecting block 506 facing the slide rail 505, a pair of guide rods 507 are provided at intervals on both sides of the threaded hole, a protrusion 508 is provided on the top of the slide rail 505, a pair of guide holes 5081 are provided on the protrusion 508, a pair of guide rods 507 are penetrated in the pair of guide holes 5081, a screw 5082 is penetrated on the protrusion 508, and the screw 5082 is threadedly connected with the threaded hole. When it is necessary to adjust the single fertilizer application amount, the screw can be loosened, and then the slide rail 505 and the rack 503 are moved outward along the guide column to disengage the rack 503 and the gear ring 502, and then the accommodating disk 4 is rotated to rotate the second arc notch 401 to be used to the bottom of the first arc notch 301, and then the slide rail 505 and the rack 503 are pushed back inward to restore the meshing and resetting of the rack 503 and the gear ring 502, and the screw is tightened.

[0031] The above are only some of the embodiments listed in this application and are not intended to limit this application.
