Description

Technical Field

[0001] The utility model relates to an automatic fertilizer spreading vehicle. Background Art

[0002] With the continuous development of society and the economy, the pace of agricultural modernization is accelerating. In this process, the use of various types of modern agricultural machinery is becoming increasingly common. For example, equipment such as seed drills, tillers, and combine harvesters play a vital role in agricultural production. These machines not only significantly reduce farmers' labor intensity but also greatly improve agricultural production efficiency.

[0003] At the same time, as people's living standards improve, the demand for green food is also growing. To meet this demand, agricultural production has begun to pay more attention to improving the growth quality of crops and striving to achieve green and circular development of agriculture. As a result, the use of green organic fertilizers is also growing.

[0004] Compared to traditional inorganic fertilizers, organic fertilizers have a high water content and tend to clump easily. Even solid organic fertilizers are prone to caking when stored in damp, poorly ventilated areas or in high-humidity weather. However, existing fertilizer spreaders often struggle to effectively handle these bulky, lumpy fertilizers. To address this issue, specialized fertilizer spreading machines—spreaders—have emerged. These machines can crush clumped organic fertilizers for easy distribution.

[0005] Currently, high-end crops require precise control of fertilizer application. However, traditional fertilizer spreaders often suffer from uneven fertilizer distribution, resulting in some crops not receiving sufficient nutrients while others may be negatively impacted by excessive fertilizer application.

[0029] (Example 1)

[0030] See Figure 1 The automatic fertilizer spreading vehicle of this embodiment includes a frame 1, a controller 2, a silo 3, a discharge mechanism 4, a fertilizer spreading mechanism 5, and a positioning device 6 arranged on the frame 1; the discharge mechanism 4 is arranged at the outlet of the silo 3, and transports the fertilizer to be spread in the silo 3 to the fertilizer spreading mechanism 5, and the positioning device 6 sends the position information of the frame 1 to the controller 2; the controller 2 adjusts the travel route of the frame 1 and the discharge amount of the discharge mechanism 4 according to the position information of the frame 1 and the preset fertilizer spreading amount per unit area.

[0031] Specifically, the frame 1 is the support and driving component of the automatic fertilizer spreader, and the controller 2 is the central brain of the automatic fertilizer spreader, responsible for receiving signals from various sensors and controlling the entire fertilizer spreading process according to a preset program. In this embodiment, the positioning device 6 is a GPS device. Through the GPS device, the controller 2 can clearly know the specific location of the fertilizer spreader in the field, which is crucial to the entire fertilizer spreading process.

[0032] The discharge mechanism 4 includes a discharge roller 4-1, which is rotatably mounted at the outlet of the silo 3. The discharge speed is controlled by controlling the rotational speed of the discharge roller 4-1. Grooves are evenly distributed along the axial direction of the discharge roller 4-1. As the discharge roller 4-1 rotates, the grooves convey the fertilizer to be spread to the fertilizer spreading mechanism 5. The rotation of the discharge roller 4-1 pulverizes large fertilizer lumps, embedding the fertilizer in the grooves and conveying it to the fertilizer spreading mechanism 5.

[0033] The discharge roller 4-1 is provided with a discharge roller rotary encoder 4-2, which measures the number of revolutions of the discharge roller 4-1 and sends it to the controller 2. By measuring the number of revolutions of the discharge roller 4-1, the amount of fertilizer spread is determined.

[0034] The fertilizer spreading mechanism 5 includes a fertilizer spreading disc with multiple spreading rods evenly arranged on its upper surface. Driven by a power unit, the fertilizer spreading disc rotates, distributing fertilizer via the spreading rods fixed to the upper surface of the disc. As a preferred embodiment of this embodiment, the spreading rods are angled with the diameter of the fertilizer spreading disc, allowing the fertilizer to be spread farther and more evenly.

[0035] A weighing sensor 7 is provided at the bottom of the silo 3. The weighing sensor 7 measures the weight of the fertilizer to be spread in the silo 3 and sends it to the controller 2. It cooperates with the rotary encoder 4-2 of the discharge roller to achieve more accurate measurement.

[0036] A silo fertilizer retaining plate 8 is provided in the silo 3 to control the speed and amount of the fertilizer to be spread flowing to the discharge mechanism 4, thereby ensuring a smooth fertilization process.

[0037] During operation, the required fertilizer amount per unit area is determined based on the crop variety, and the total fertilizer amount required is calculated based on the total area occupied by the crops. The operator inputs the predetermined route into controller 2, and the fertilizer spreader follows the predetermined route while spreading fertilizer. Based on the spreader's positioning information, controller 2 continuously adjusts its route and the movement of the discharge roller 4-1 to ensure that the fertilizer is evenly distributed according to the specified pattern. Simultaneously, a weighing sensor 7 continuously monitors the weight changes of the fertilizer in the silo 3 and combines this with data from the discharge roller's rotary encoder 4-2 to precisely control the fertilizer spread rate. This ensures uniform fertilizer distribution, whether traveling in a straight line or turning, significantly improving fertilization efficiency and land utilization.

[0038] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
