Abstract
The utility model discloses a discharge outlet regulating device for a compound pendulum jaw crusher. The regulating device comprises a movable jaw and a pull rod, wherein one end of the pull rod is connected with a hook at the lower part of the movable jaw, a compression spring is sheathed on the other end of the pull rod, one end of the compression spring is propped against the outer side of the bottom of a rack, the other end of the compression spring is propped against a gland, the gland is fixed by double nuts screwed with the pull rod, a tray is arranged between the compression spring and the outer side of the bottom of the rack and has a semisphere structure and is correspondingly connected with a groove at the outer side of the bottom of the rack, so that the compression spring and the rack are not easily worn under the to-and-fro impact action of the movable jaw, the tray and the rack can keep close connection, and the discharge outlet can be opened and closed normally; and the included angle alpha formed by the pull rod and a horizontal line ranges from 15 degrees to 20 degrees, the load of the crushing region at the upper part of the movable jaw can be reduced, and the efficiency of the crushing region at the lower part can be improved.
Description
Technical field
The utility model relates to a kind of disintegrating machine, especially a kind of single toggle jaw crusher discharge gate adjusting device.
Background technology
Existing single toggle jaw crusher discharge gate adjusting device is by making the pull bar running under the drive of moving jaw, and at moving jaw back and forth under the percussion, make compression spring and frame junction damage easily, cause normally folding of discharge gate, disintegrating machine will quit work; And existing pull bar and horizontal line are on same horizontal line, and moving jaw top fracture area load is bigger, and disintegrating machine efficient at work is lower.
The utility model content
At above-mentioned situation, the utility model purpose is to provide a kind of compression spring and frame not easy to wear, can improve the single toggle jaw crusher discharge gate adjusting device of crushing efficiency.
The technical solution of the utility model is: a kind of single toggle jaw crusher discharge gate adjusting device, comprise moving jaw and pull bar, one end of pull bar is connected with hook place, moving jaw bottom, the other end is with the compression spring, one end of compression spring withstands the frame bottom outside, the other end withstands gland, gland is thread on the double nut of pull bar and fixes, be provided with a pallet between described compression spring and the frame bottom outside, pallet be " hemispherical " structure and with the corresponding connection of groove of frame bottom outside, the angle ɑ that pull bar and horizontal line constitute is 15 °～20 °.
The beneficial effects of the utility model are: the corresponding connection of groove of " hemispherical " pallet and frame bottom outside between compression spring and the frame bottom outside, make compression spring and frame not easy to wear under the percussion back and forth at moving jaw, and can make pallet and frame keep closely being connected, normally folding of discharge gate; The angle ɑ that pull bar and horizontal line constitute is 15 °～20 °, makes the top fracture area of jaw reduce load, and the bottom fracture area is raised the efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram at A place among Fig. 1;
Fig. 3 is the structural representation of the angle ɑ of pull bar of the present utility model and horizontal line formation.
Among the figure: moving jaw 1, pull bar 2, compression spring 21, gland 22, double nut 23, pallet 24, frame 3, groove 31.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of single toggle jaw crusher discharge gate adjusting device, comprise moving jaw 1 and pull bar 2, one end of pull bar 2 is connected with hook place, moving jaw 1 bottom, the other end is with compression spring 21, one end of compression spring 21 withstands frame 3 bottom outside, the other end withstands gland 22, it is fixing that gland 22 is thread on the double nut 23 of pull bar 2, be provided with a pallet 24 between described compression spring 21 and frame 3 bottom outside, pallet 24 be " hemispherical " structure and with the groove 31 corresponding connections of frame 3 bottom outside, make compression spring 21 and frame 3 not easy to wear under the percussion back and forth at moving jaw 1, and can make pallet 24 keep closely being connected normally folding of discharge gate with frame 3; Pull bar 2 is 15 °～20 ° with the angle ɑ that horizontal line constitutes, and makes the top fracture area of jaw 1 reduce load, and the bottom fracture area is raised the efficiency.
