Abstract
The utility model relates to a locking device for plate hammers, wherein the barb of a plate hammer seat A is barbed on a support plate; a fastening bolt on the support plate tightly jacks the plate hammer seat A, and then tightly jacks the plate hammer; the plate hammer seat A is also protected by two protective plates forming an angle of 45 degrees; and a plate hammer seat B tightly pressed and welded by the welded plate hammer seat protective plates is arranged at the other side of the plate hammer. Three plate hammers in a rotor are connected with the plate hammer seats in a clamping manner via two convex ledges respectively, and the convex ledges are as long as the plate hammers, thus enhancing the strengths of the plate hammers; the parts which cannot be used at the middles are thinner, thus increasing the utilization rates of the plate hammers, and saving materials and resources; the plate hammers are in zero-clearance fit with the plate hammer seat A and cannot fall off during working, thus ensuring the safety of operation personnel; and the plug-in plate hammer seat A can still be fixed during a wear process, thus facilitating detachment and maintenance work. The locking device for the plate hammers has the characteristics of simple structure, strong practicability and long service life, and is easy to install, detach and maintain.
Description
Technical field
The utility model belongs to the disintegrating machine technical field, relates to the bar locking device in a kind of disintegrating machine.
Background technology
Disintegrating machine is that granularity accounts for the size reduction machinery of total discharge weight more than 50% greater than three millimeters content in a kind of discharge, and impact breaker is to utilize the high speed impact of bar and the rebound effect of counterpunch board, makes material be subjected to repeated stock and broken machinery.Bar is packed on the high speed rotor rotated, and press different angles along crusher chamber and arrange some counterpunch boards, existing sand machine rotor processed mainly fixes bar by the bar seat backplate welding with two ends, the loosening situation of bar will appear but service time is long, thereby cause equipment fault, influenced the normal operation of equipment.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art
,The utility model provide a kind of simple in structure, practical, be easy to install, dismantle and the bar locking device of maintenance, long service life characteristics.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of bar locking device; comprise and be arranged on bar one side according to the bar seat A of the plug-in type of fixed-direction installation; the barb of bar seat A is hooked on the gripper shoe; fastening bolt on the gripper shoe holds out against bar seat A; and then hold out against bar; bar seat A also is subjected to the backplate of two welding at 45 again and protects, and is provided with the bar seat B of a welding of pressing by the bar seat backplate of welding at the opposite side of bar.
Described bar and bar seat A, bar seat B are by two fin clampings.
The beneficial effects of the utility model are: three bars in the rotor are respectively by two fins and the clamping of bar seat phase, fin is identical with bar length, compare with existing short fin or groove, improved bar intensity, use in the middle of can making less than that part of thinner, improved the utilization rate of bar, saved material, saved resource, wherein bar seat A joins work at last, be that no gap cooperates between bar and the bar seat A like this, bar and the formed chucking of bar seat position are more firm, can not come off during work, guaranteed operating personnel's safety, the bar seat A of plug-in type still can keep fixing in wear process, also made things convenient for dismounting and maintenance work simultaneously, has simple in structure, practical, be easy to install, dismounting and maintenance, the characteristics of long service life.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-bar, 2-bar seat A, 3-gripper shoe, 4-fastening bolt, 5-bar seat B, 6-fin, 7-bar seat backplate.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1; a kind of bar locking device; comprise and be arranged on bar 1 one sides according to the bar seat A2 of the plug-in type of fixed-direction installation; the barb of bar seat A2 is hooked on the gripper shoe 3; fastening bolt 4 on the gripper shoe 3 holds out against bar seat A2; and then hold out against bar 1; bar seat A2 also is subjected to the backplate of two welding at 45 again and protects; be provided with the bar seat B5 of a welding of pressing by the bar seat backplate 7 of welding at the opposite side of bar 1, bar 1 and bar seat A2, bar seat B5 are by two fin 6 clampings.
Three bars in the utility model rotor are respectively by two fins 6 and the clamping of bar seat phase, fin 6 is identical with bar length, compare with existing short fin 6 or groove, improved bar 1 intensity, use in the middle of can making less than that part of thinner, improved the utilization rate of bar 1, saved material, saved resource, wherein bar seat A2 joins work at last, be that no gap cooperates between bar and the bar seat A2 like this, bar 1 is more firm with the formed chucking of bar seat position, can not come off during work, guaranteed operating personnel's safety, the bar seat A2 of plug-in type still can keep fixing in wear process, also made things convenient for dismounting and maintenance work simultaneously, has simple in structure, practical, be easy to install, dismounting and maintenance, the characteristics of long service life.
