Description

Technical Field

[0001] This utility model relates to the field of crop fertilization technology, and in particular to a self-propelled liquid manure precision application device. Background Technology

[0002] Fertilizers play a crucial role in crop growth, primarily providing the essential nutrients needed by plants to promote growth and development. However, a mismatch between fertilizer application and crop requirements often occurs. Insufficient fertilizer application reduces crop yield, while excessive application decreases nutrient utilization and can cause problems such as ammonia volatilization and nitrogen and phosphorus leaching. Therefore, there is an urgent need to develop precision fertilizer application equipment to improve nutrient utilization and reduce environmental pollution. This is of great significance for achieving cost reduction and efficiency improvement in my country's grain production and promoting sustainable agricultural development.

[0003] Meanwhile, with the continuous improvement of people's living standards, the demand for livestock and poultry products is constantly increasing, leading to the rapid development of my country's livestock and poultry farming industry and the generation of a large amount of liquid manure. Liquid manure contains rich nutrients. By returning liquid manure to the fields in a timely and appropriate manner, it can not only replenish soil nutrients and ensure the sustainable production capacity of farmland, but also improve the quality of agricultural products. This is extremely important for solving the environmental pollution caused by livestock and poultry farming and improving the utilization rate of nutrient resources.

[0004] The patent with publication number CN115316099A discloses a drag-tube type liquid manure application equipment, which injects liquid organic manure directly and quantitatively into farmland from a closed manure storage tank through a hose, realizing the most efficient utilization of liquid manure nutrients. It does not require attaching a liquid manure tank or going back and forth to fill the tank, and is highly efficient and low in cost.

[0005] The aforementioned liquid manure application equipment is susceptible to uneven application due to variations in travel speed. Therefore, a more efficient, unattended application device for precisely returning liquid manure from livestock and poultry farms to the fields is urgently needed to promote sustainable agricultural development.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 and 2 As shown, this embodiment provides a self-propelled liquid manure precision application device, including a frame 12, wheels, a roller 9, a cable, a ratchet mechanism 10, a flywheel 4, a swivel joint 2, a spraying arm 1, and a spraying head 24. Wheels are provided on both sides of the frame 12. The roller 9 is mounted on the frame 12 and located at the front end of the frame 12. One end of the cable is wound around the roller 9, and the other end of the cable is used to connect to a fixed object in the field. The lower end of the swivel joint 2 is connected to the output end of the fertilizer pipe, and the upper end of the swivel joint 2 is connected to one end of the spraying arm 1. The other end of the spraying arm 1 is equipped with a spraying head 24. The flywheel 4 is coaxially connected to the upper end of the swivel joint 2. The flywheel 4 is driven by the ratchet mechanism 10. The ratchet mechanism 10 is driven by the roller 9.

[0027] In this specific embodiment, the ratchet 10 mechanism includes a rocker arm 5, a pawl 6, a ratchet 10, a tension spring 7, and a check pawl 27; multiple transmission teeth are arranged circumferentially on the circumferential surface of the flywheel 4; the lower end of the rocker arm 5 is rotatably connected to the frame 12, and the upper end of the rocker arm 5 is in contact with the transmission teeth; one end of the tension spring 7 is connected to the middle part of the rocker arm 5, and the other end of the tension spring 7 is connected to the frame 12; one end of the pawl 6 is rotatably connected to the upper middle part of the rocker arm 5, and the other end of the pawl 6 is in contact with the ratchet teeth of the ratchet 10; one end of the check pawl 27 is rotatably connected to the frame 12, and the other end of the check pawl 27 is in contact with the ratchet teeth on the ratchet 10; the ratchet 10 is coaxially fixedly arranged with the roller 9.

[0028] The top of the rocker arm 5 is provided with a roller shaft 3, and a roller 3 is provided on the roller shaft 3. The roller 3 contacts the transmission teeth of the flywheel 4 to reduce the wear of the flywheel 4.

[0029] A return spring 8 is provided between the pawl 6 and the rocker arm 5. The return spring 8 can keep the pawl 6 at a preset height and can also adapt to the angle change when the pawl 6 pushes the ratchet 10, so that the pawl 6 can push the ratchet 10 to rotate more stably.

[0030] A rocker arm base 11 is provided between the rocker arm 5 and the frame 12. An amplitude adjuster 26 is provided between one side of the rocker arm base 11 and the lower part of the rocker arm 5. The amplitude adjuster 26 includes an adjusting screw, which is threadedly connected to the rocker arm base 11. One end of the adjusting screw contacts the side wall of the rocker arm 5. By adjusting the depth of the adjusting screw into the rocker arm base 11, the distance between the top of the rocker arm 5 and the flywheel 4 can be adjusted, thereby adjusting the maximum swing amplitude of the rocker arm 5. This allows the forward speed of the application device to be changed without changing the spray angle of the spray head 24.

[0031] A rocker arm seat spacer 19 is provided inside the rocker arm base 11, and a rocker arm spacer 20 is provided between the rocker arm seat spacer 19 and the rocker arm 5. The rocker arm spacer 20 is used to reduce wear between the bottom of the rocker arm 5 and the rocker arm base 11.

[0032] An electronic flow meter 21 and an electronic butterfly valve 22 are installed between the lower end of the rotary joint 2 and the output end of the fertilizer pipe. The electronic flow meter 21 and the electronic butterfly valve 22 are used to detect and control the amount of fertilizer applied.

[0033] A rotary joint 23 is provided between the spraying arm 1 and the spraying head 24.

Both ends of the rotary joint 23 are threaded, and the rotary joint 23 is threaded to the spraying arm 1 and the spraying head 24 respectively. By manually rotating the rotary joint 23, the angle between the two ends of the rotary joint 23 is changed, thereby adjusting the horizontal angle between the spraying direction and the spraying arm 1. This changes the horizontal component of the force received by the spraying arm 1, and thus changes the rotation speed of the spraying arm 1 while keeping the spraying pressure constant, ultimately adjusting the overall travel speed of the application device.

[0034] The lower part of the fertilizer application pipe is connected to the upper end of a bypass pipe. The lower end of the bypass pipe is equipped with a guide groove 25, and the front end of the guide groove 25 is a furrow opener. The lower end of the bypass pipe is connected to the rear end of the furrow opener. During the movement of the application device, the furrow opener is inserted into the soil to a certain depth. As the application device moves, the furrow opener opens a fertilizer furrow in the soil.
