Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a three-variable controllable anti-clogging mixed fertilization device. Background Art

[0002] The solution to ecological problems is imminent, but the current level of agricultural development in China is still far behind that of Western countries. Fully and effectively utilizing limited resources and developing modern agriculture with the goal of saving land, water, and fertilizers are the focus of China's agriculture. According to a survey by the Food Organization of the United Nations (FAO), chemical fertilizers contribute 40% to 60% to agricultural production, 41.43% to improving soil productivity, and 53.89% to improving labor productivity. Outdated fertilization machinery and fertilization methods not only lead to poor fertilizer utilization by crops during fertilization, but also cause soil compaction and eutrophication of water bodies due to fertilizers not absorbed by crops, which pollutes the environment.

[0003] In view of the problems existing in the existing controllable variable fertilizer spreaders, the present invention proposes a three-variable controllable anti-clogging mixed fertilization device. It has three variables, which are controlled in time and segmented manners and completed in collaboration. The opening of the fertilizer slot a (independent variable), the thickness of the fertilizer disc h (independent variable), the displacement v (dependent variable) of the fertilizer disc after one rotation, and the size of the flow rate V (dependent variable) under different speeds n (independent variable). First, when the opening of the fertilizer slot remains unchanged and the thickness of the disc remains unchanged, different flow rates V can be achieved by changing the speed n of the fertilizer disc. As the speed of the fertilizer disc continues to increase, the fertilizer cavity of the fertilizer disc cannot be guaranteed to be filled, so when the speed reaches a certain value, the flow rate cannot continue to be increased, and the flow rate regulation is limited. Second, when the speed regulation is limited, the filling volume can be guaranteed by changing the opening a of the fertilizer slot. The opening of the fertilizer slot is controlled by the steering gear, and its angle can be accurately controlled. The maximum opening is 30°, that is, the corresponding position of the fertilizer disc hole and the fertilizer box changes from a single hole to a hole to a slot, the fertilizer drop stroke increases, the fertilizer drop time becomes longer, and the filling volume is guaranteed. However, the speed cannot be increased infinitely. The higher the speed, the more unstable the fertilizer disc is, the more likely it is to be eccentric, and the requirements for the mechanical manufacturing level are also greater, so the fertilizer amount is limited again. Third, when the speed is limited, even if the filling volume is met, the required flow rate V cannot be reached. The third variable, the thickness h of the fertilizer disc, can be changed. By changing the thickness h of the fertilizer disc, the thickness h is increased under the condition of ensuring the filling volume, the volume of a single fertilizer cavity is increased, the displacement is increased, and the flow rate is also increased. Fourth, the minimum fertilization adjustment method is the same as the maximum fertilization adjustment method, and the minimum fertilization amount can be adjusted. Therefore, by adjusting the three variables, a larger fertilization flow range can be obtained. 5. Regarding the setting of the anti-blocking device, the air compressor generates gas, and the pneumatic reversing valve ensures the gas flow. The pressure sensor detects the unblocked condition of the fertilizer drop hole. The pressure sensor is installed on the slope of the anti-blocking fertilizer drop pipe. The pressure sensor transmits a signal to Arduino. If the blockage PWM display statistical curve changes from a peak and trough type to a strip or linear growth, it means that the fertilizer drop hole is blocked. Arduino outputs instructions to control the air compressor and the pneumatic electromagnetic reversing valve to generate air pressure and blow open the blocked part. Summary of the invention
