Abstract

The utility model relates to a hard straw grinder comprising a grinding cavity and a grinding roll which is rotatably arranged in the grinding cavity, wherein a material inlet and a material outlet are respectively arranged in two ends of the grinding cavity, a screening plate is arranged below the grinding roll, the size of the end of the grinding roll, close to the material outlet, is smaller than that of the other end of the grinding roll, grinding teeth are arranged on the grinding roll, and the grinding roll is connected with a power mechanism. According to the hard straw grinder disclosed by the utility model, the size of the end of the grinding roll, close to the material outlet, is smaller than that of the other end of the grinding roll so that the grinding space between the grinding roll and the screening plate is becomes smaller and smaller from the material inlet to the interior, the blockage of straw is unlikely to occur, the grinding capability is strong, the application range is wide, the continuity of grinding operation can be ensured, the working efficiency is high and the unit energy consumption is low.

Description

A kind of hard stalk crasher
Technical field
The utility model belongs to the disintegrating apparatus technical field, particularly a kind of hard stalk crasher.
Background technology
In recent years, along with the fast development of China's Biomass Energy Utilization, the stalk crasher that matches with Biomass Energy Utilization is development thereupon also.At present, there is certain defect in hard stalk crasher common on market: 1, breaker roll is that equal diameter is cylindrical, and stalk enters too much when too fast, causes easily that in crusher chamber, stalk blocks, and makes the breaker roll can't normal rotation, affects the equipment normal operation; 2, existing disintegrating machine intensity is limited, when running into the hard stalk of the rhizome such as tobacco rod, and broken difficulty, easy cause damage of equipment, and energy consumption is higher.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, be difficult for to block, the scope of application is wide and energy consumption is low hard stalk crasher.
For achieving the above object, the technical solution of the utility model is: a kind of hard stalk crasher, comprise and rotate the breaker roll that arranges in crusher chamber and crusher chamber, the crusher chamber two ends are respectively equipped with charging aperture and discharging opening, the breaker roll below is provided with sieve plate, the nearly discharge port end size of described breaker roll is less than other end size, and breaker roll is provided with crushing teeth, and breaker roll is connected with actuating unit.
Described breaker roll is hexagon, is evenly equipped with six row crushing teeths on breaker roll.
Described crusher chamber is provided with bearing block and bearing, and breaker roll is arranged in bearing by the rotating shaft of end; Roller end is provided with driving wheel, and driving wheel is connected with motor by belt transmission.
Described crusher chamber bottom is provided with access panel.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model comprises the breaker roll that rotates setting in crusher chamber and crusher chamber, the crusher chamber two ends are respectively equipped with charging aperture and discharging opening, the breaker roll below is provided with sieve plate, the nearly discharge port end size of described breaker roll is less than other end size, breaker roll is provided with crushing teeth, breaker roll is connected with actuating unit, simple in structure, due to the nearly discharge port end size of breaker roll less than other end size, broken space between itself and sieve plate is inwardly diminished gradually from charging aperture, be difficult for causing stalk to block, breaking capacity is strong, the scope of application is wide, can guarantee the continuation of broken work, high efficiency, specific energy consumption is low.
2, the crusher chamber bottom is provided with access panel, is convenient to equipment is carried out repair and maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Hard stalk crasher as depicted in figs. 1 and 2 comprises the breaker roll 4 that the interior rotation of crusher chamber 1 and crusher chamber 1 arranges, and the two ends of crusher chamber 1 are respectively equipped with charging aperture 2 and discharging opening 3, and the below of breaker roll 4 is provided with sieve plate 11, is evenly equipped with sieve aperture on sieve plate 11.Breaker roll 4 is hexagon, and the nearly discharge port end size of breaker roll 4 is evenly equipped with six row crushing teeths 5 less than other end size on breaker roll 4, and crushing teeth 5 is fin shape, and crushing teeth 5 is provided with sawtooth.Be provided with bearing block and bearing 7 on crusher chamber 1, breaker roll 4 two ends are provided with rotating shaft 6, and breaker roll 4 rotates by the rotating shaft 6 of end and is arranged in bearing block and bearing 7.Be provided with driving wheel 8 in the end of rotating shaft 6, driving wheel 8 is connected with motor 10 by belt 9, and the power of crushing straw is provided for breaker roll 4.For just with maintenance, be provided with access panel 12 in the bottom of crusher chamber 1.
Due to the nearly discharge port end size of breaker roll 4 less than other end size, broken space between itself and sieve plate 11 is inwardly diminished gradually from charging aperture 2, breaker roll 4 is hexagon, further increased again the broken space between breaker roll 4 and sieve plate 11, be difficult for causing stalk to block, breaking capacity is strong, can guarantee the continuation of broken work, high efficiency.
