Description

Backpack Fertilizer

technical field

The utility model relates to a top dressing device.

Background technique

At present, when topdressing crops, farmers need to bend down and spread the fertilizer into the furrows with their hands. The work efficiency is extremely low. In case of windy weather, the fertilizer will be blown onto the leaves of the plants and cause harm to the host plants. In order to save fertilizers, some farmers use hoes to dig holes beside the plants to fertilize, but the labor intensity is high and the work efficiency is low. The utility model patent with the authorized announcement number CN200956731Y and the authorized announcement date on October 10, 2007 discloses a backpack type fertilizer applicator. Although it solves the problems of low work efficiency and easy blowing of fertilizer, it has the problem of using fertilizer Large amount of fertilizer, less fertilizer absorption, easy to block the fertilizer outlet and soil compaction.

Utility model content

The purpose of the utility model is to solve the problems of the existing top dressing device that the fertilizer outlet is easily blocked and the fertilizer consumption is large, and further provide a backpack type top dressing device.

The technical scheme of the utility model is: the knapsack top dressing device includes a fertilizer storage box, a box cover, a fertilizer filter, a hose, a first valve, a second valve, an inner tube, an outer tube, two straps, an end cover, a plurality of Connecting rod and quantitative cylinder, two straps are arranged on the side wall of the fertilizer storage box, the cover is installed on the upper end surface of the fertilizer storage box, the fertilizer filter is installed in the fertilizer storage box, the One end of the bottom plate of the fertilizer storage tank communicates with one end of the hose placed outside the fertilizer storage tank, the other end of the hose is connected to one end of the metering cylinder, and the connection between the hose and the metering cylinder is provided with a first valve, The other end of the dosing cylinder is connected to the fertilizer inlet end of the inner pipe, and a second valve is provided at the connection between the dosing cylinder and the inner pipe, the fertilizer outlet end of the inner pipe is inserted into the outer pipe, and the end cover passes through multiple The root connecting rod is fixedly connected to the end face of the fertilizer output end of the outer pipe.

Compared with the prior art, the utility model has the following beneficial effects: the utility model effectively prevents the blockage of the fertilizer outlet, realizes quantitative and positioned topdressing, reduces the labor intensity of farmers, and improves the efficiency of topdressing. The utility model also has the advantages of simple structure and flexible operation.
