Carrier fertilizer

Abstract

The invention discloses a backpack type fertilizer application device. The backpack type fertilizer application device comprises a fertilizer storage barrel with shoulder straps and a flexible pipe with the upper end connected to an outlet of the fertilizer storage barrel, the lower end of the flexible pipe is in butt joint with a connecting pipe, and the front end of the connecting pipe is fixedly provided with an installation block. The installation block is provided with an upper cavity, a middle cavity and a lower cavity which are arranged vertically side by side, the front end of the connecting pipe is fixedly inserted into the rear end of the upper cavity, and a fertilizer application pipe is inserted into the front end of the lower cavity. A first outlet communicated with the middlecavity is formed in the upper cavity, a second outlet communicated with the lower cavity is formed in the middle cavity, and the first outlet is staggered with the second outlet. A quantification block is slidably installed in the middle cavity, the quantification block is provided with a quantification cavity, an upper opening and a lower opening are formed in the quantification cavity, and thequantification block is connected with a driving device and a reset device. The backpack type fertilizer application device which is simple in structure and convenient to use is thus provided, and thebackpack type fertilizer application device is especially suitable for quantitatively applying a small amount of a fertilizer.

Description

technical field [0001] The invention relates to the technical field of agricultural implements, in particular to a backpack type fertilizer applicator. Background technique [0002] At present, plants need to be fertilized to ensure the nutrients for growth during the planting process. Traditional fertilization is extensive watering, which has problems such as uneven distribution, inaccurate location, and inaccurate amount. With the development of refined planting, fertilizers for some plants need to be applied in a quantitative and targeted manner. Especially when topdressing landscape crops such as potted flowers, a small amount of fertilizer is required to be given quantitatively to the soil surface in the pot. At present, there is no device available on the market that can be used for quantitative fertilization of plants. In fact, it can only be done manually. For large-scale planting, the workload is very heavy, which is not only laborious, but also not conducive to sav...

Problems solved by technology

[0007] The above-mentioned technical solutions can realize quantitative fertilization in theory, but it is inconvenient to use in practice, and it is not suitable for the quantitative application of a small amount of fertilizer, mainly because on the one hand, the fertilizer quantitative device requires operator experience and hand speed High, unable to ensure the consistency of the amount of fertilizer delivered each time; on the other hand, due to overall structural problems, the fertilizer is prone to jamming from the lower end of the hose, and it is necessary to shake the applicator at the lower end to make the fertilizer fall, which is not only inconvenient to use, but also Moreover, the loss of fertilizer transportation from the quantitative device to the fertilizer application port is large, resulting in insufficient fertilizer application.
