Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0012] The present invention uses a screw adjusting device to replace the worm gear adjusting device in the prior art to adjust the gap between the ring hammer and the sieve plate of the ring hammer crusher. image 3 is an embodiment of the present invention, Figure 4 yes image 3 It is a schematic diagram of the cooperation mode of the embodiment integrated in the ring hammer crusher. Such as image 3 As shown, the first connecting rod 25 is hinged with the sieve plate frame 22 through the second pin shaft 5; the screw rod 43 is threaded on the car, and the head has a "T" groove, and the pin is inserted into the "T" groove. 41 is hinged with the first connecting rod 25; the other end of the screw mandrel 43 is milled into a square, and the square head can be clamped by a wrench to drive the screw mandrel 43 to rotate. Due to the effect of the second pin...

The invention discloses a gap adjusting device which is convenient to be assembled and between a perforated plate and a ring hammer of a ring hammer type crusher. The invention comprises a perforated plate frame which is fixed together with the perforated plate and a first connecting rod which is connected with the perforated plate frame in a rotatable mode, wherein the first connecting rod is connected with one end of a connecting lead screw in the rotatable mode, a feed screw nut is screwed on the connecting lead screw, the feed screw nut is installed on a retaining bracket of the feed screw nut, the retaining bracket of the feed screw nut is fixed on a frame of the ring hammer type crusher, and the feed screw nut can be moved on the retaining bracket of the feed screw nut along a direction which is vertical to the lead screw. When the lead screw rotates, the first connecting rod can be driven to rotate by rotations of the lead screw, thereby the perforated plate frame can be driven to rotate, and the device which is provided by the invention can be functioned to adjust a gap between the perforated plate and the ring hammer. Compared with a turbine worm device which is adopted by the prior art, the invention has simple structure, convenient manufacture, and easy assembly.
Description
technical field [0001] The invention relates to a ring hammer crusher, in particular to a device for adjusting the gap between the sieve plate and the ring hammer in the ring hammer crusher. Background technique [0002] At present, the adjustment device used to adjust the gap between the crusher screen plate and the ring hammer in the ring hammer crusher generally adopts a worm gear device, such as figure 1 and figure 2 shown. figure 1 It is a schematic diagram of the coordination of the ring hammer, crushing plate, sieve plate and gap adjustment mechanism in the ring hammer crusher with the worm gear adjustment device. figure 2 yes figure 1 The worm gear adjustment device used in the Such as figure 2 As shown, the bow-shaped sieve plate 1 is fixed on the sieve plate frame 22, and the sieve plate frame 22 can rotate around the first pin shaft 3, so as to approach or move away from the ring hammer 2; The connecting rod 25 is hinged, and the rotation of the sieve fra...
