Technical Field

[0001] This utility model relates to the field of fertilizer applicator technology, specifically to a fertilizer uniform spreading mechanism for a traction fertilizer applicator. Background Technology

[0002] Fertilizer applicators are specialized mechanical equipment designed to meet the needs of agricultural operations. They can be classified into solid fertilizer applicators, liquid fertilizer applicators, and manure spreaders according to the fertilizer properties. They are generally divided into two main types: towed and suspended.

[0003] Existing small-scale tractor-mounted fertilizer applicators use rotating scrapers to accelerate and throw out fertilizer that falls onto the receiving tray, thus achieving uniform fertilizer spreading. However, this method has the following drawbacks in actual use: during fertilizer spreading, material blockage occurs in areas such as the fertilizer tank support and tractor body, affecting spreading uniformity and causing fertilizer waste. In addition, the spreading range cannot be adjusted, making it difficult to meet different usage needs. Furthermore, during fertilizer transportation, blockages can easily occur due to fertilizer characteristics and moisture levels, affecting spreading uniformity. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4As shown, the fertilizer spreading mechanism of the traction fertilizer applicator includes a frame 100 and a material receiving plate 200 installed on its outer side. The material receiving plate 200 is equipped with a set of scrapers 210 and also includes an adjustment mechanism 300. The adjustment mechanism 300 is located on the outer side of the material receiving plate 200 and is used to adjust the spreading range. The adjustment mechanism 300 also includes an arc-shaped sleeve 310 and two arc-shaped plates 320. One end of the arc-shaped plate 320 extends into the interior of the arc-shaped sleeve 310, and the ends of the two arc-shaped plates 320 away from the arc-shaped sleeve 310 form discharge ports. The arc-shaped plates 320 can move in a circular motion along the axis of the material receiving plate 200.

[0017] When performing fertilizer spreading operations, the user can pre-adjust the position of the arc plate 320 to change the size of the discharge port. The area where the arc box 310 and the arc plate 320 are located is the fertilizer blocking area. Then the fertilizer is introduced into the receiving tray 200, and then the scraper 210 rotates, driving the fertilizer to accelerate and then being discharged along the discharge port, thus completing the uniform spreading of fertilizer. It should be noted that the fertilizer box is pre-installed on the frame 100 so that the discharge pipe of the fertilizer box corresponds to the receiving plate 200, and the tractor is connected to the frame 100 so that the traction operation is completed after the tractor runs. The top of the scraper 210 is bent to reduce fertilizer runoff. The rotating spreading method of the scraper 210 is a mature technology. The specific spreading of fertilizer depends on the specifications and speed of the scraper 210. The top of the material receiving tray 200 is recessed to facilitate the collection of fertilizer, ensure the acceleration path of the scraper 210 after it is driven, and make the fertilizer spreading distance and uniformity better.

[0018] A rotating shaft is provided on the material receiving tray 200, and a spiral guide vane 220 is provided on the outside of the rotating shaft.

[0019] The end of the rotating shaft and the spiral guide plate 220 are placed into the fertilizer box discharge pipe. The rotating shaft drives the spiral guide plate 220 to rotate, which helps to transport the fertilizer to the receiving plate 200, reducing the occurrence of blockage, thereby ensuring continuous fertilizer discharge and uniform spreading. It should be noted that a crossbar is provided between the rotating shaft and the scraper 210 to connect the two and drive the scraper 210.

[0020] The top of the arc-shaped sleeve 310 is provided with a baffle cover 311, and the baffle cover 311 has a through hole inside.

[0021] By using the material blocking cover 311, accidental splashes of fertilizer can be blocked and intercepted, reducing fertilizer waste.

[0022] The inner side of the arc plate 320 is provided with a set of grooves, and a compensating strip 321 is slidably connected in the grooves. One side of the compensating strip 321 is provided with a chamfer, and a set of springs 322 is provided between the compensating strip 321 and the grooves.

[0023] The compensation strip 321 can compensate for the space on the arc plate 320, and together with the material receiving plate 200, it forms a good receiving space for fertilizer, ensuring the driving effect of the scraper 210. When the arc plate 320 is pulled out along the arc-shaped sleeve 310, the spring 322 will drive the corresponding compensating strip 321 to move along the groove. When the arc plate 320 moves into the arc-shaped sleeve 310, the chamfer of the compensating strip 321 can abut against the opening of the arc-shaped sleeve 310, improving storage efficiency.

[0024] The arc-shaped sleeve 310 and the arc-shaped plate 320 are connected by threads, and the arc-shaped plate 320 has a set of threaded holes.

[0025] The multi-point threaded hole design allows users to flexibly adjust the position of the arc plate 320 according to their needs, forming fertilizer spreading and discharging ports of varying degrees.

[0026] The frame 100 is equipped with two wheels and a set of ear plates.

[0027] One side lug connects to the tractor body, and the user can connect the plow blade to the other side lug for soil turning to meet different fertilization needs. During tractor operation, the walking wheels drive the frame to follow the movement.

[0028] A motor 230 is installed below the material receiving tray 200, and the output shaft of the motor 230 is connected to the rotating shaft through a coupling.

[0029] The motor 230 is used to drive the rotating shaft and the spiral guide vane 220 to move in a corresponding manner to complete the fertilizer driving operation; It should be noted that the motor 230 is powered by a battery, which can be installed on the frame 100.

[0030] Working principle: The user pre-pulls the two arc plates 320 to adjust the spreading range, then fixes them with bolts. Next, the frame 100 is pre-connected to the tractor, and then the fertilizer box is installed so that the spiral guide vane 220 is in the fertilizer box discharge pipe. Then the tractor operates, pulling the frame 100 to move. During this process, fertilizer is discharged onto the receiving plate 200. Then the motor 230 operates, driving the scraper 210 to spread and discharge the material on the receiving plate 200.
