Chemical fertilizer crushing device for agriculture

Abstract

The invention discloses a chemical fertilizer crushing device for agriculture. The device comprises a box body, wherein the left side surface of the box body is fixedly connected to two first fixing rods, and the opposite surfaces of the two first fixing rods are fixedly connected to the upper surface and the lower surface of a first driving device respectively; and the first driving device is correspondingly meshed with a second gear and a third gear, the right side surface of the second gear is fixedly connected to a first rotating shaft, and the surface of the first rotating shaft is sleeved with two first bearings. According to the chemical fertilizer crushing device for the agriculture, a first motor, a first gear, the second gear, the third gear, the first rotating shaft, a second rotating shaft, first teeth, second teeth, a filtering plate, a movable block, a sliding rod, an extruding plate, a first connecting rod, a second connecting rod, a rotating disc and a second motor arecoordinated with each other to enable chemical fertilizer capable of passing through screening holes rapidly, the utilization rate of the chemical fertilizer is increased, and the crushing effect of the chemical fertilizer is more rapid and complete under the condition that the time and the crushing treatment amount of the chemical fertilizer are same.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to an agricultural chemical fertilizer crushing device. Background technique [0002] Chemical fertilizers refer to chemically manufactured or mined ore and processed fertilizers, also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. They have the following common characteristics: simple ingredients, nutrients High content; fast fertilizer effect, strong fertilizer; some fertilizers have acid-base reaction; generally do not contain organic matter, and have no effect of improving soil and fertilizing. There are many types of chemical fertilizers, and their properties and application methods are quite different. [0003] When maintaining farmland, chemical fertilizers are often directly spread on the field. Since many chemical fertilizers are granular, they will...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an agricultural chemical fertilizer crushing device, which solves the problem of directly spreading chemical fertilizers in the field during farmland maintenance. Since many chemical fertilizers are granular, they will be damp when placed in a cool and humid place for a long time. , causing the granular chemical fertilizers to condense into blocks, which cannot be dissolved in time after they are directly spread, making their use efficiency inefficient and causing great waste. Moreover, chemical fertilizers have irritating gases that are harmful to the human body, and they are placed in the field for a long time Problems of human inhalation affecting human health
