Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a fertilizing device for improving the fertility of high-standard farmland. Background Art

[0002] During the construction of high-standard farmland, fermented manure (including compost and retting) is used for fertilization to ensure soil fertility. This fertilization process is typically carried out using a fertilizer spreader. This fertilizer spreader consists of a wheeled chassis and a fertilizer tank. The tank is mounted on the wheeled chassis and equipped with a fertilizer scraping chain. A spreading device is located at the rear of the tank.

[0003] After the fertilizer spreader finishes spreading fertilizer, a certain amount of manure will remain in the fertilizer box. Since there is generally no car washing equipment in farmland, this part of the fertilizer can only be simply rinsed manually, which is more troublesome to manually clean the fertilizer box.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown, this embodiment discloses a fertilizing device for improving the fertility of high-standard farmland, including a wheeled chassis 1, a traction bracket 2 towed by a power machine is provided at the front of the wheeled chassis 1, a fertilizer box 3 is provided above the wheeled chassis 1, and a spreading device 4 is provided below the rear of the fertilizer box 3.

[0019] The fertilizer box 3 is provided with a fertilizer scraper chain 5. This is typically an annular structure, with the upper portion located within the fertilizer box 3 and the lower portion located below the box. The function of the fertilizer scraper chain 5 is to scrape the fertilizer in the fertilizer box 3 backwards to the rear of the box 3 for discharge. Sprocket shafts are mounted at both the front and rear ends of the bottom of the fertilizer box 3. The sprocket shafts at both ends of the fertilizer box 3 are connected by a closed conveyor chain, and the sprocket shafts are mounted on the sprocket shafts to cooperate with the conveyor chain. The front of the fertilizer box 3 is provided with an opening to facilitate the passage of the conveyor chain, while the rear of the fertilizer box 3 is open. In this embodiment, one of the sprocket shafts of the fertilizer scraper chain 5 is connected to a hydraulic motor, which drives the fertilizer scraper chain 5. The structure of the fertilizer scraper chain 5 and its installation on the fertilizer box 3 are prior art, and its detailed structure is not repeated here.

[0020] A baffle 11 is provided above the front of the fertilizer box 3, and the baffle 11 extends backward. The baffle 11 is provided with several front nozzles 6 in different directions on one side surface facing the rear of the fertilizer box 3. The front nozzles 6 can flush the inside of the fertilizer box 3. Each front nozzle 6 is connected to the water supply device 7 through a pipe, and the water supply device 7 is provided on the traction bracket 2.

[0021] The water supply device 7 mainly includes a water tank 701 and a water pump 702. One port of the water pump 702 is connected to the water tank 701, and the other port is connected to a water distributor 703. Several water outlets on the water distributor 703 are connected to corresponding front nozzles 6 through pipes. The water pump 702 can be driven by a hydraulic motor.

[0022] In this embodiment, a flip-up tailgate 8 is provided at the rear open position of the fertilizer bin 3. The upper portion of the tailgate 8 is pivotally connected to the fertilizer bin 3. Hydraulic cylinders 9 are provided on both sides of the tailgate 8. The working ends of the hydraulic cylinders 9 are hinged to the side walls of the tailgate 8, and the main bodies of the hydraulic cylinders 9 are hinged to the fertilizer bin 3. The hydraulic cylinders 9 extend and retract to drive the tailgate 8 open, thereby changing the gap between the lower edge of the tailgate 8 and the fertilizer scraping chain 5, thereby controlling the amount of fertilizer discharged.

[0023] In this embodiment, a plurality of rear nozzles 10 facing the scattering device 4 are provided on the tailgate 8. The rear nozzles 10 can flush the scattering device 4. The rear nozzles 10 are connected to the water outlet on the water distributor 703 through pipes.

[0024] like Figure 2As shown, the spreading device 4 includes a receiving trough 401, which is connected to the rear of the fertilizer box 3. A horizontal fertilizer-beating and spreading roller 402 is provided in the receiving trough 401. The horizontal fertilizer-beating and spreading roller 402 includes a roller shaft 402-1, which is rotatably connected to the receiving trough 401. One end of the roller shaft 402-1 is connected to the power of a hydraulic motor. A plurality of crushing and spreading fertilizer blades 402-2 are provided on the outer circular wall of the roller shaft 402-1. When the fertilizer falls from the rear of the fertilizer box 3 and enters the receiving trough 401, the fertilizer is crushed by the crushing and spreading fertilizer blades 402-2 and scattered backwards.

[0025] It should be noted that the traction machinery is generally a tractor, which has its own hydraulic system. The hydraulic motor and the hydraulic cylinder in this embodiment can be connected to the hydraulic system on the tractor.

[0026] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
