Problems solved by technology

The above structure is to control the amount of fertilizer falling due to gravity by adjusting the cross-sectional size of the feeding port. This structure can realize real-time control of the amount of fertilizer discharge within a certain range, but when the opening of the feeding port is small, it is limited by the diameter of the fertilizer particles The impact may lead to blockage and make the fertilizer discharge unstable. Therefore, the variable range of variable fertilization by controlling the cross-sectional size of the feed opening is small, and the variable accuracy is low

Abstract

The invention relates to a variable fertilizer spreading device and a variable fertilizer spreading method. The variable fertilizer spreading device comprises a fertilizer container and a fertilizer spreading disc which are placed on a mobile device, the variable fertilizer spreading device further comprises a fertilizer conveying pipe, one end of the fertilizer conveying pipe communicates with the fertilizer container, the other end of the fertilizer conveying pipe is located above the fertilizer spreading disc, and a spiral blade is arranged in the fertilizer conveying pipe in a matched mode. The spiral blade is connected with a first motor for driving the spiral blade to rotate, the fertilizer spreading disc is connected with a second motor for driving the fertilizer spreading disc to rotate, the first motor and the second motor are both connected with a motor controller for controlling the rotating speed of the first motor and the rotating speed of the second motor, and the motor controller is electrically connected with a control device; and the control device is further electrically connected with a speed detection device used for measuring the moving speed of the moving device. The variable fertilizer spreading device can be used as an independent operation system, the matching applicability is wide, the fertilizer flow change is adjusted through the rotating speed of the spiral blade, variable fertilizer spreading is achieved, the variable precision is high, and the variable range is wide.

Description

technical field [0001] The invention relates to the field of fertilizer spreading machinery, in particular to a variable variable fertilizer spreading device and a variable variable fertilizer spreading method. Background technique [0002] Fertilizer pollution is mainly the phenomenon of water, soil and air pollution caused by the application of large amounts of chemical fertilizers in agriculture. It can lead to eutrophication of rivers, lakes and inland seas; soil pollution, deterioration of physical properties; increase of toxic components in food, feed and drinking water. In order to prevent pollution of the environment, the chemical fertilizers used should be controlled and managed. [0003] In response to the above problems, the existing Chinese patent with the publication number CN106856763A discloses a real-time variable manure spreader based on crop growth information, including a variable manure spreader system, which consists of a bracket, a fertilizer box, a dr...
