A rotor type liquid fertilizer precise application quantitative device

Abstract

The invention discloses a rotor-type liquid fertilizer accurate application quantifying device and belongs to the field of agricultural machinery. The rotor-type liquid fertilizer accurate applicationquantifying device is characterized in that two 'L'-shaped bases are welded at the front and the rear of the lower side of an outer barrel in a back-to-back manner; a liquid inlet and a liquid outletare formed in the front of the outer side of the outer barrel by means of welding; an inner rotary drum is mounted inside the outer barrel via a front rotary drum bearing and a rear rotary drum bearing; a front end cover and a rear end cover are fixed to the outsides of the front end and the rear end of the outer barrel by the aid of screws; a planetary gear device is mounted in the inner rotarydrum; a gear wheel shaft of a periodic fertilizer discharge device is fixedly welded with the front end cover; a piston fertilizer storage device is fixedly connected onto an opening in a side wall ofthe inner rotary drum, a piston rod of the piston fertilizer storage device is connected with a push rod of the periodic fertilizer discharge device in a contact manner, and the piston rod can be pushed by the push rod, so that the piston fertilizer storage device can be in a fertilizer outgoing state, and liquid fertilizer can flow out from the liquid outlet. The rotor-type liquid fertilizer accurate application quantifying device has the advantages that a piston can be pushed by the push rod to be exactly positioned at the maximum stroke location when the piston reaches the liquid outlet, accordingly, the liquid fertilizer in a piston barrel can be discharged, and the quantity of the liquid fertilizer can be accurately controlled.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a rotor type liquid fertilizer precise application quantitative device. Background technique [0002] China is the largest agricultural country in the world. Chemical fertilizer is an important material input in agriculture and the basis for increasing crop yields; according to statistics, China’s chemical fertilizer application accounted for nearly 40% of the world’s application in 2016; a large number of granular chemical fertilizers are used, although It has brought about a huge increase in production and income, but at the same time it has brought about problems such as soil structure damage, ecological environment pollution, and the decline in the quality of agricultural products. Liquid fertilizer is a liquid fertilizer containing nutrient elements for crop growth. It has the characteristics of zero dust, zero smoke and less pollution. Compared wi...

Foliar spraying is mainly used in large fields. A well-proportioned liquid fertilizer is sprinkled on the top of the plants, and the liquid fertilizer falls to the surface of the leaves of the plants under the action of its own weight to promote the absorption of nutrients by the plants. This method pollutes a lot and the utilization rate of fertilizers is not good. high

Drip irrigation is mainly used in facility agriculture. Liquid fertilizer is applied to each plant on demand through arranged fertilizer pipes. This method requires a large amount of equipment investment in the early stage, and the cost is high. It is not suitable for field crops.
