Problems solved by technology

[0004] In order to solve the technical problems of processing temperature and processing efficiency in making fertilizer sticks, the present invention provides a fertilizer stick extrusion molding device, which feeds the fertilizer into the extrusion device through the feeding hopper, and the fertilizer is squeezed by the screw propeller of the extrusion device under the forceful extrusion process. The temperature of the material rises to the appropriate temperature under pressure and friction, and then the fertilizer is made into columnar particles through the first wide and then narrower formed discharge head cover column-shaped empty tube channel, and then dried to obtain fertilizer sticks that meet the requirements of crop production.

Abstract

The invention relates to the technical field of agricultural machine and specifically relates to a device for extrusion moulding of a fertilizer stick. This device comprises a feeder hopper, an extrusion device, a moulding discharge head, a power device and a frame. The feeder hopper is arranged at one end of the extrusion device far away from the moulding discharge head; the extrusion device is composed of an extrusion cavity and a spiral propeller placed in the extrusion cavity and is propelled by rotation of the power device; the moulding discharge head is a cylindrical hard head with a length of 10-15 centimeters, 1-7 cylindrical blank pipes are uniformly arranged at an intermediate part; the cross-sectional area of a discharge hatch of the cylindrical blank pipe is less than that of a feed inlet by 5%-10%; the moulding discharge head is connected with a discharge end of the extrusion device; the power device is arranged below the extrusion device of the frame, and the power device drives the spiral propeller of the extrusion device for rotation by a transmission mechanism. By using the device for extrusion moulding of the fertilizer stick, the produced fertilizer stick is firm, slow release effect is good, and production efficiency is high.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a fertilizer bar extruding device. Background technique [0002] Fertilizer bar is a kind of fertilizer that is required for the growth and development of crops and processed into a bar shape, and a certain proportion of stabilizers, plasticizers and partial gelling agents are added to make the fertilizer required for crop growth into a fertilizer bar. When top dressing is applied to the soil at one time, the film in the fertilizer stick that can slow down the dissolution and the synthetic resin that is difficult to dissolve is added inside to prolong the fertilizer effect period, so that the crops can continuously receive fertilizer supply throughout the growth period, reducing labor costs and improving planting benefits. [0003] The use of fertilizer bars in agricultural production is mostly limited to flower cultivation management at present, and the manufacturing metho...
