Abstract
The utility model discloses a gear tooth type graded crusher which is composed of a frame. The frame is provided with a crushing chamber, the top and the bottom of the crushing chamber are respectively provided with a feeding inlet and a discharge hole, a crushing roller with gear teeth is arranged in the crushing chamber, the crushing roller is driven by a drive mechanism, and the side surface of the crushing chamber is provided with a primary screening chamber. The bottom of the primary screening chamber has a discharge hole, the discharge holes at the bottoms of the primary screening chamber and the crushing chamber are both led to and arranged at a total discharge hole which is arranged at the bottom of the crusher, the top of the primary screening chamber has a feeding inlet which is adjacently connected with the feeding inlet of the crushing chamber, the feeding inlet of the crushing chamber is internally provided with a plurality of conveying screen rollers which can rotate and have the conveying direction toward the crushing chamber in parallel from outside to inside, a gap which is used for material blocks with qualified volume to pass through is arranged between every two adjacent conveying screen rollers, and each conveying screen roller is driven by the drive mechanism through a transmission mechanism. When the gear tooth type graded crusher works, the primary screen separation is carried out on materials in the primary screening chamber to cause materials to carry out current division, thereby reducing the blockage phenomenon existing in the prior crusher efficiently, and enhancing the crushing capability of the whole crusher.
Description
Technical field
The utility model relates to disintegrating apparatus, especially the gear tooth-type Sizing Crusher.
Background technology
Existing gear tooth-type Sizing Crusher is mainly used in the fragmentation of raw coal, in crushing chamber, be provided with a pair of breaker roll, two breaker roll upper edges are axially arranged with the gear teeth, material is poured directly on the feeding mouth of crusher chamber when work, coal cinder not of uniform size falls together, its broken classification is to realize in crusher chamber, and the bulk raw coal roller that is broken beats pulverizing, pulverizes the piece material that requires and directly falls to discharging from blanking port and meet; The problem that existing gear tooth-type Sizing Crusher exists is: when the bulk raw coal is mingled with under the bigger situation of fritter and raw coal continuous flow, the fritter raw coal can not in time be discharged and can be produced jam, when the humidity of coal is big, a large amount of wet coals can stick between two groups of gear teeth, also can produce jam.
The utility model content
The purpose of this utility model is to provide a kind of can carry out the gear tooth-type Sizing Crusher that primary screen divides does not influence blanking velocity again before pulverizing.
The technical solution of the utility model is: the gear tooth-type Sizing Crusher, comprise frame, frame is provided with crushing chamber, the top of crushing chamber, the bottom be respectively equipped with into, discharging opening, be provided with the breaker roll that has the gear teeth in the crushing chamber, driving mechanism on breaker roll and the fixed frame is in transmission connection, described crushing chamber side is provided with the primary dcreening operation chamber, bottom, primary dcreening operation chamber has discharging opening, the discharging opening of primary dcreening operation chamber and crushing chamber bottom all feeds the total discharging opening that is arranged at the disintegrating machine bottom, top, primary dcreening operation chamber has the feeding mouth with the feeding mouth adjacency of crushing chamber, ecto-entad is provided with the conveying sieve roller of a plurality of rotating throughput directions towards crushing chamber side by side in the feeding mouth of primary dcreening operation chamber, but be provided with the gap that the long-pending qualified material piece of donor passes through between each adjacent conveyor sieve roller, each carry sieve roller by transmission mechanism by the drive mechanism that is fixed on the frame.
The bottom of described pulverizer is provided with total discharging opening, and the discharging opening of primary dcreening operation chamber and crushing chamber bottom all feeds in the total discharging opening that is arranged at the disintegrating machine bottom.
Described each carry roll shaft one end of sieve roller to be equipped with travelling gear, engaged transmission is equipped with carrier gear between the adjacent travelling gear, carry in the sieve roller one of them carry the roll shaft of sieve roller by being fixed on motor-driven on the frame.
The utility model is provided with the primary dcreening operation chamber in the feeding mouth one side adjacency of pulverizing chamber, adopted the rotational conveyance structure of conveying sieve roller arranged side by side on this primary dcreening operation chamber, material enters crushing chamber again after carrying the elementary screening of sieving roller on the primary dcreening operation chamber, most of satisfactory coal cinder can directly leak down from the gap between the adjacent conveyor sieve roller and fall into discharging opening, the material that remaining volume is bigger is admitted to pulverizing chamber soon and carries out fragmentation under the drive of the conveying sieve roller that rotates, because material has carried out elementary screening in the primary dcreening operation chamber and with material diversion, like this under the situation that does not influence overall mass flow, mass flow in the pulverizing chamber diminishes, thereby can effectively reduce the jam that existing pulverizer exists, improve the breaking capacity of complete machine.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, the utility model comprises frame 14, frame 14 is provided with crushing chamber 2, crushing chamber 2 sides are connected with primary dcreening operation chamber 1, be provided with the breaker roll 3 that has the gear teeth in the crushing chamber 2,4, breaker roll 3,4 respectively by being fixed on motor 11 on crushing chamber 2 machine frame at two sides, 12 drive, the top of primary dcreening operation chamber 1 and crushing chamber 2 is provided with the feeding mouth that adjoins each other, ecto-entad is provided with the conveying sieve roller 7 of a plurality of throughput directions towards crushing chamber side by side in the feeding mouth of primary dcreening operation chamber 1, but be provided with the gap that the long-pending qualified material piece of donor passes through between each adjacent conveyor sieve roller 7, each carries roll shaft one end of sieve roller 7 to be equipped with travelling gear 5, engaged transmission is equipped with carrier gear 6 between the adjacent travelling gear 5, one of them carry the roll shaft of sieve roller 7 motor 8 drive on the frame 14 by being fixed on, the bottom of primary dcreening operation chamber 1 and crushing chamber 2 is equipped with discharging opening, and the discharging opening of primary dcreening operation chamber 1 and crushing chamber 2 bottoms all feeds in total discharging opening 13 of disintegrating machine bottom.
The utility model is when work, material is admitted under the drive of the conveying sieve roller 7 of the rotation on 1 top, primary dcreening operation chamber and carries out fragmentation in the crushing chamber 2, in the process that material is advanced on carrying sieve roller 7, directly fall in the slit of the qualified material piece of volume between adjacent conveyor sieve roller 7 and with crushing chamber 2 broken good material piece discharge from total discharging opening 13 in the lump, the material of the needs fragmentation that volume is bigger is admitted to pulverizing chamber 2 soon and carries out fragmentation under the drive of roller 7 is sieved in the conveying of rotating.
