Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a solar-powered, terrain-adaptable tractor-type fertilizer spreader. Background Technology

[0002] Traditional methods of applying solid fertilizer mainly involve using small tractors to pull agricultural transport vehicles to unload the fertilizer at certain intervals into the field and pile it up, followed by manual spreading of the fertilizer in the field. This method of applying solid fertilizer is labor-intensive, has high labor intensity, and a poor working environment. In addition, the fertilizer is spread unevenly and the work efficiency is low, which directly affects the economic benefits and work efficiency of large-scale planting. Currently, most towed fertilizer spreaders still rely on fuel for power and have poor adaptability to terrain. For example, existing technology CN205284144U discloses a manure spreader that uses fuel from a tractor for power. This increases fuel consumption, greenhouse gas emissions, and environmental pollution, and the narrow spreading range is caused by the spreading rollers being placed on both sides. Existing technology CN2715497Y discloses a ground-wheel driven manure spreader. While this device solves the problem of relying on fuel for power, it suffers from uneven spreading on uneven roads due to the characteristics of the ground wheels, resulting in poor terrain adaptability. Existing technologies CN205284144U and CN214102283U both disclose an electric three-wheeled manure spreader. Although it solves the problem of relying on fuel for power, its complex structure makes it unsuitable for spreading solid granular fertilizer and prone to fertilizer blockage. Therefore, it is necessary to propose a solar-powered, terrain-adaptable towed fertilizer spreader to solve the above problems. Utility Model Content

The motor 13 is connected to the extension platform of the front baffle 23 of the fertilizer bin 2. The battery 14 is fixedly placed in the waterproof cover 15. The motor 13 and the battery 14 are connected by wires, replacing the previous traction machinery to provide power, reducing fuel consumption and greenhouse gas emissions.

[0028] The fertilizer silo 2 includes an upper cover 21, a rear baffle 22, a front baffle 23, a silo bottom 24, and a feed cover 25. The rear baffle 22 and the front baffle 23 are respectively located at the rear and front of the silo bottom 24. The upper cover 21 is located above the silo bottom 24, and the feed cover 25 is located on the upper cover 21. The feed cover 25 is connected to the upper cover 21 by a pin. A side cover plate is provided on the lower side of the upper cover 21. The silo bottom 24 is trapezoidal with a narrow bottom and a slope of 280°.

[0029] The drive device 3 includes a spiral auger 31, a spreading disc 32, a first bearing seat 33, a second bearing seat 34, and a coupling 35. The front and rear ends of the spiral auger 31 are connected to the first bearing seat 33 and the second bearing seat 34 respectively and fixed inside the fertilizer bin 2. The axis of the spiral auger 31 is parallel to the bearing axis of the first bearing seat 33 and the second bearing seat 34. The front and rear ends of the spiral auger 31 are mounted in the bearing holes of the first bearing seat 33 and the second bearing seat 34. The first bearing seat 33 and the second bearing seat 34 are fixed on the rear end baffle 22 and the front end baffle 23 of the fertilizer bin 2 respectively. The front end of coupling 35 is connected to the power output shaft of motor 13 by a pin, and the rear end of coupling 35 is connected to the front shaft of screw conveyor 31. The spreading disc 32 is connected to the extension of the rear end of the bin bottom 24 via a smooth shaft. The connection point covers the front half of the fertilizer outlet. A partition is installed between the two spreading discs 32, which are symmetrically placed on both sides of the partition. The nearest edge of each spreading disc 32 is 3cm from the partition, and the upper surfaces of both spreading discs 32 are on the same horizontal plane. The axes of both spreading discs 32 are vertically upward. The bottom of the spreading disc 32 can rotate, replacing the previous large bin, avoiding fertilizer waste and increasing the spreading area. The upper end of the spreading disc 32 has eight curved blades. One end of each blade is connected to the center of the spreading disc 32, and the other end is evenly distributed in a circular pattern. The tangents of adjacent blades form a 45° angle.

[0030] The chassis 4 includes wheels 41, a crossbeam 42, a slope adapting device 43, a hydraulic rod 44, a chassis frame 45, a support rod 46, and a traction ring 47. The wheels 41 are located at both ends of the crossbeam 42, which is welded to the slope adapting device 43. The slope adapting device 43 is connected to the chassis frame 45 via pins.

The traction ring 47 is located at the end of the chassis frame 45. The slope adapting device 43 is Y-shaped with two curved branches, made of high-strength spring steel. When traversing uneven surfaces, its unique structure transmits the bumpy force generated by the fertilizer hopper 2 and its constituent structures to both ends of the slope adapting device 43, releasing the force onto the branches and converting it into a low-potential-energy elastic force, thus reducing the weight of the chassis. This allows it to adapt to different road conditions during operation, improving the device's adaptability.

[0031] The actuating roller 5 is mounted on a vertical bearing seat 51, which is installed on the rear end boss of the bin bottom 24, with its axis parallel to the bearing axis of the vertical bearing seat 51. The actuating roller 5 has ten circumferentially distributed blade bins, each with an included angle of 36°, and each bin has a 0.5cm gap between its bottom end and the bin bottom 24 when rotating. The actuating roller 5 can evenly receive the fertilizer conveyed by the auger 31, preventing clogging caused by excessive rotation speed of the spreading disc 32 during operation, and ensuring the uniformity of fertilizer application.

[0032] This utility model provides a solar-powered, terrain-adaptive traction fertilizer spreader. Its working principle is as follows: Before operation, fertilizer is poured into the fertilizer bin through the feed cover. The fertilizer accumulates at the bottom along the trapezoidal inclined wall. The traction device is connected to the traction ring of the chassis, and the solar panel is adjusted to a sunny location using the solar panel adjustment frame. During operation, the operator controls the motor switch via a remote control compatible with the power supply. When the motor is at a suitable speed, it transmits power to the auger through the coupling. As the traction device pulls the fertilizer spreader forward, the fertilizer is pushed along the bottom of the bin by the auger blades into the chamber of the agitator roller. The agitator roller rotates as the fertilizer is conveyed forward, evenly distributing the fertilizer into the chambers of the spreading disc. Due to the pushing force of subsequent fertilizer and the fertilizer's own gravity, the fertilizer in the chambers of the spreading disc is discharged.

[0033] When the traction device runs out of power or fuel, the operator can use a remote control to stop the motor and replenish the traction device's energy.

[0034] When the device stops operating, the fertilizer in the fertilizer bin is emptied by raising the hydraulic rod and unloaded from the traction device. The support rod is then pulled downward so that the bottom of the support rod contacts the ground, keeping the device in a horizontal position. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0035] This device is compared with similar fertilizer applicators on the market in terms of energy consumption, amount of waste gas generated, fertilizer discharge efficiency, labor and fuel costs per acre, as shown in Table 1.
