A rotary plunger type straw granulator

Abstract

The invention provides a rotary plunger type straw granulator. The rotary plunger type straw granulator comprises a first rolling die, a second rolling die, a charging chamber, discharging chambers, connecting rods and a mechanism, wherein material extruding heads and forming holes, which are of staggered arrangement, are formed in each of the first and second rolling dies, the material extruding heads on the first rolling die extend into the forming holes of the second rolling die, the material extruding heads on the second rolling die extend into the forming holes of the first rolling die, compression holes are formed in the heads of the forming holes, and the inside diameter of the compression holes is greater than or equal to the outside diameter of the material extruding heads and decreases gradually; cutters are arranged in the discharging chambers; the connecting rods are arranged between end faces of the same sides of the first and second rolling dies; the mechanism is used for increasing the extruding force of the material extruding heads. The rotary plunger type straw granulator has the beneficial effects that the work efficiency is high, the reactive power loss is low, and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a rotary plunger type straw granulator for extruding biomass such as straw, weeds and branches into granules. Background technique [0002] With the advancement of science and technology, in addition to direct accumulation and combustion of crop straw, people often process it into pellets to improve combustion efficiency and meet higher-level needs. The existing straw granulator is mainly a flat die rolling granulator or a ring die rolling granulator, which has low working efficiency, high energy consumption, high requirements on the humidity and crushing degree of raw materials, and has a low service life and is prone to failure . Patent application number 201020519186.9 and authorized announcement number CN201841002U propose a dual-mode mutual-extrusion straw granulator, which consists of two rolling dies, and each rolling die is evenly equipped with an extrusio...

The existing straw granulator is mainly a flat die rolling granulator or a ring die rolling granulator, which has low working efficiency, high energy consumption, high requirements on the humidity and crushing degree of raw materials, and has a low service life and is prone to failure

Patent application number 201020519186.9 and authorized announcement number CN201841002U propose a dual-mode mutual-extrusion straw granulator, which consists of two rolling dies, and each rolling die is evenly equipped with an extrusion head and a forming hole. The forming holes are arranged staggeredly. There are compression holes at the heads of the forming holes. The middle part of the rolling die is the discharge cavity, and a cutter is installed in the discharge cavity: the extrusion head of one rolling roll extends to the end of the other rolling roll. In the forming hole, the extrusion head of the other rolling roller extends back into the forming hole of this rolling roller. The double-mode mutual-pressing and inter-extruding straw pellet machine has low energy consumption, high efficiency and low requirements for raw materials. , but the die hole of the equipment is easy to block or material accumulates around the die, which affects the efficiency of granulation work, increases reactive power loss, and even causes shutdown, and cannot be opened quickly after shutdown, and there are many faults in use
