[0016] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0017] A fertilizer box for an agricultural machinery fertilizer spreader includes a fertilizer box body 1. The lower side of the fertilizer box body 1 is provided with two opposite inclined side plates 16. Both inclined side plates 16 are inclined inward from top to bottom. A long strip-shaped feeding opening 2 is formed between the bottom of the two inclined side plates 16. The two inclined side plates 16 are respectively connected to vertical side plates 17 extending upward. A fertilizer box front end plate 23 and a fertilizer box rear end plate 7 are respectively installed at both ends of the fertilizer box body 1.

[0018] The fertilizer box body 1 is equipped with a scraper conveyor on the lower side of the discharge opening 2. The scraper conveyor includes a housing 3 connected to the fertilizer box body 1. The top of the portion of the housing 3 inside the fertilizer box body 1 is open and communicates with the discharge opening 2 at the bottom of the fertilizer box body 1. The fertilizer inside the fertilizer box body 1 enters the housing 3 directly through the discharge opening 2 and the opening at the top of the housing 3.

[0019] The scraper conveyor described in this utility model has the structure of a common scraper conveyor in the current market. Two chains 4 are rotatably installed inside the housing 3. The chains 4 are fitted onto two sprockets. The sprockets on both sides of the chains 4 are driven to rotate by a rotating shaft mounted on the side plate 13 of the housing. One of the rotating shafts on the front and rear sides is connected to the drive sprocket.

[0020] Multiple scrapers 5 are installed at intervals between the chains 4 on both sides. The scrapers 5 are driven to rotate by the chains 4 on both sides. As the multiple scrapers 5 on the chains 4 on both sides rotate toward the discharge end, the scrapers 5 will transport the fertilizer that falls into the housing 3 toward the discharge end and throw the fertilizer toward the side of the bottom plate 6 that extends out of the rear end plate of the housing 3, and then throw the fertilizer toward the discharge port 8.

[0021] The housing 3 includes a base plate 6, one end of which extends rearward to the rear end plate 7 of the fertilizer box body 1. A lower discharge port 8 is provided on the rear side of the chain 4 on the base plate 6. The housing 3 is box-shaped and includes side plates 13 arranged opposite to each other on both sides, a front plate 22 arranged opposite to each other on both sides, and a rear end plate. The rear end plate 7 extends rearward from the side of the housing 3 near the discharge port, and a cover plate 11 is provided on the rear side of the rear end plate 7. The side plates 13 extend upward from the rear side of the rear end plate 7 to form an extension plate, which is connected to both sides of the cover plate 11. The front ends of the extension plate and the cover plate 11 are welded to the rear end plate 7, respectively. The rear end of the cover plate 11 is connected to the rear end plate of the housing 3.

[0022] A valve 9 is installed on the lower discharge port 8. The valve 9 is a gate valve. The gate valve is driven by a hydraulic cylinder to move the gate, which in turn drives the valve 9 to open and close.

[0023] The bottom of the rear end plate 7 of the fertilizer box has an upward-facing side discharge port 10. The side discharge port 10 is located between the two side plates 13 of the two shells and below the cover plate 11, that is, the side discharge port 10 is between the cover plate 11 and the two side plates 13 of the two shells. This utility model can control the amount of material pushed by the scraper 5 on the scraper conveyor at one time by controlling the opening size of the side discharge port 10. When the opening of the side discharge port 10 becomes larger, more material is discharged at one time; when the opening of the side discharge port 10 becomes smaller, less material is discharged at one time.

[0024] The top of the cover plate 11 has a limiting hole. A telescopic cylinder 14 is installed on the upper side of the fertilizer box rear end plate 7. The telescopic cylinder 14 is a hydraulic cylinder, and the piston rod of the telescopic cylinder 14 is connected to a limiting plate 15 inserted into the limiting hole. This utility model controls the opening size of the side discharge hole by setting the limiting plate 15 and driving the limiting plate 15 to move up and down by the telescopic cylinder 14. When the telescopic cylinder 14 drives the limiting plate 15 to move downward, the opening of the side discharge hole becomes smaller; when the telescopic cylinder 14 drives the limiting plate 15 to move upward, the opening of the side discharge hole becomes larger.

[0025] Mounting bases are connected to the left and right sides of the fertilizer box body 1. The mounting base includes a base plate 18 with multiple fixing holes. An outer vertical plate 19 and an inner vertical plate 20 are respectively installed on the left and right sides of the base plate 18. A diagonal brace 21 connects the outer vertical plate 19 and the inner vertical plate 20. The diagonal side plates 16 on both sides are respectively placed on the diagonal brace 21. The upper side of the outer vertical plate 19 is connected to the vertical side plate 17 by bolts and nuts.

[0026] This utility model uses two mounting seats on both sides to mount the fertilizer tank body 1 onto the chassis of the fertilizer spreading vehicle, ensuring a secure installation. During installation, first, the base plate 18 on the two mounting seats is placed onto the chassis of the fertilizer spreading vehicle, aligning the fixing holes on the base plate 18 with the mounting holes on the chassis. Then, the base plate 18 is fixedly connected to the chassis using bolts and nuts. Next, the two inclined side plates 16 of the fertilizer tank body 1 are placed onto the two inclined support plates 21, and finally, the outer vertical plate 19 is fixedly connected to the vertical side plate 17 using bolts and nuts.

[0027] The front end of the housing 3 is provided with a front end plate 22, which extends forward beyond the front end plate 23 of the fertilizer box body 1, and the front end plate 22 has an arc-shaped plate structure. The inner diameter of the arc-shaped plate in this invention is slightly larger than the rotation radius of the scraper 5.

[0028] The fertilizer spreading process of this utility model is as follows: When spreading fertilizer, first open valve 9, then start the scraper conveyor. At this time, when the lower discharge port 8 on the scraper conveyor is located at the right end of the bottom plate 6, we can observe from the front side of the scraper conveyor that the chain 4 and scraper 5 on the scraper conveyor are rotating clockwise. The chains 4 on both sides inside the scraper conveyor drive multiple scraper 5 to rotate. The scraper 5 rotating to the upper side will transport the fertilizer that has fallen into the housing 3 to the discharge end and throw the fertilizer to the side of the bottom plate 6 that extends out of the rear end plate of the housing 3, and then throw the fertilizer to the lower discharge port 8. Finally, the fertilizer flows out from the lower discharge port 8. When the fertilizer in the fertilizer box body 1 is finished spreading and the fertilizer is concentrated on the lower side of the housing 3, we reverse the scraper conveyor. At this time, the scraper 5 on the scraper conveyor will scrape the fertilizer on the lower side of the housing 3 into the lower discharge port 8, thereby avoiding the accumulation of material in the housing 3. When this invention does not require fertilizer application, such as when walking on the road, we can close valve 9 to effectively prevent leakage.
