Abstract
The invention discloses a toothed roller of a crushing machine. The toothed roller of the crushing machine comprises a roller drum and arc-shaped toothed plates, wherein a dovetail-shaped block is transversely arranged in the middle of the inner wall of each arc-shaped toothed plate, at least two bolt holes are formed in the connection line between every two dovetail-shaped blocks in the circumferential wall of the roller drum, countersunk-head bolts are mounted in the bolt holes among the arc-shaped toothed plates, a positioning block is arranged on one side of the roller drum between each row of bolts and each dovetail-shaped block, and a movable press block is arranged between one bolt and one dovetail-shaped block on the other side of the positioning block in an inserted mode. According to the toothed roller of the crushing machine, a dovetail-shaped locking mechanism between each arc-shaped toothed plate and the roller drum is used for fixing the toothed roller, and therefore the toothed roller of the crushing machine has the advantages that the structure is simple, the accuracy is high and the toothed plates can be replaced conveniently.
Description
Technical field:
The present invention relates to mechanical part, particularly a kind of fixing firm, change tooth plate cracker teeth roller easily and fast.
Background technology:
Existing cracker teeth roller is comprised of a roller and polylith arc tooth plate, and it is connected and fixed mode and is: a kind of employing wedge piece plate, a kind of is to adopt the wire drawing type locking mechanism of inserting.Being locked of wedge piece tooth plate is to use that piece of weight is urgent to be installed fixingly, gets a piece during replacing and clashes into or remove with forcing press, takes a lot of work, time-consuming, effort; Although adopt the wire drawing locking of inserting to improve the convenience of installing, firmly performance reduces, use for a long time yieldingly, make and change difficulty, take a lot of work equally, time-consuming, effort.Two kinds of fixed forms are long because of the replacing time, all can cause completely and shut down, and impact is produced.
Summary of the invention:
The purpose of this invention is to provide a kind of fixing firmly, change tooth plate cracker teeth roller easily and fast.
Technical scheme of the present invention is completed as follows, it includes roller and arc tooth plate, it is characterized in that: be horizontally arranged with respectively a dovetails in the middle of the inwall of each piece arc tooth plate, be respectively equipped with at least two bolts hole on the line between each dovetails on the circle wall of roller, in each bolt hole, countersunk bolt is installed respectively between each arc tooth plate, be respectively equipped with locating piece on the side roller between each row bolt and dovetails, be inserted with respectively movable holddown between the bolt of locating piece opposite side and dovetails.The present invention is fixed discaling roll by the dovetail retaining mechanism between each piece arc tooth plate and roller, has simple in structurely, and precision is high, change tooth plate advantage easily.
Description of drawings:
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is local structure for amplifying schematic diagram of the present invention.
The specific embodiment:
Describe by reference to the accompanying drawings embodiment in detail.The present invention laterally is provided with respectively a dovetails 2 in the middle of the inwall of each piece arc tooth plate 1, be respectively equipped with at least two bolts hole on the line between two dovetails on the circle wall of roller 6, in each bolt hole, countersunk bolt 4 is installed respectively between each two arc tooth plates, be provided with locating piece 5 on the side roller between each row bolt and dovetails, be inserted with respectively movable holddown 3 between the bolt of locating piece opposite side and dovetails.First each piece arc tooth plate is close to during installation and is arranged on each locating piece, be tightened by bolts after inserting movable pressing board, can make between each arc tooth plate and be locked on roller, when removing tooth plate, after unclamping bolt, movable pressing board separates with dovetails automatically, be slightly quick release arc lower tooth plate with external force, have simple in structurely, precision is high, the advantage of easy disassembly and maintenance.
