Valve opening control mechanism of lawn fertilizer distributor

Abstract

The invention discloses a valve opening control mechanism of a lawn fertilizer distributor, which is mounted on a fertilizer distributor product, and comprises a four-link mechanism and a fertilizer distributor. The four-link mechanism comprises a wrench, a connecting rod, a rotating plate, a push-and-hold handle and a hopper box; the rotating plate is respectively connected with a valve push-pullrod and a valve limit rod; a valve push-pull rod is connected with a valve mounted on a valve guide seat; a leakage plate is installed under the hopper box; the leakage plate and the bottom part of the hopper box are arranged with leakage holes; the valve limit rod is installed on a limit guide rail bracket; a reset spring sleeves the valve limit rod; the top of the valve limit rod is provided with a limited position pin; according to the valve opening control mechanism of the lawn fertilizer distributor, the structure design is reasonable; in the process of lawn curing, the fertilizer application amount can be adjusted to meet the control of valve opening size; the control mechanism can ensure that the amount of fertilizer thrown by the multi-machine walking at the same time is the same,so as to achieve the accurate measurement of fertilizer amount; the amount of fertilizer applied each time can be controlled and the efficiency of fertilizer application can be improved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a valve opening control mechanism of a lawn fertilizer applicator. Background technique [0002] Fertilization refers to the agricultural technical measures of applying fertilizer to the soil or spraying it on the lawn to provide the nutrients needed by the lawn, and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, fertilize soil and improve economic benefits. Therefore, rational and scientific fertilization is one of the main means to ensure food security and maintain sustainable agricultural development. The maintenance and management of the lawn directly affects the growth and use of the lawn. A lot of improper work or insufficient maintenance work may cause the growth of the lawn to weaken and even cause the death of the grass seedlings. During the maintenance of the lawn, the state of the lawn is differ...
