Abstract
The utility model relates to an expanding protection device of a crushing cutter set of a straw crushing machine. The expanding protection device comprises the crushing cutter set and an expanding protector, wherein the crushing cutter set comprises two cutter shafts and a plurality of sheets of crushing blades; the two cutter shafts are correspondingly provided with a plurality of sheets of the crushing blades which are mutually staggered and distributed; any one cutter shaft is externally connected with a power input; and the expanding protector is a connecting plate with two through holes; and the two cutter shafts are respectively arranged in the two through holes. The expanding protection device is simple in structure, can effectively solve the expanding force between the cutter shafts, prolongs the service life of the shaft for crushing, and meets the crushing requirements.
Description
Technical field
The utility model relates to a kind of disintegrating apparatus, is a kind of cutting tool varicose protective device for stalk crusher specifically.
Background technology
Living beings various straws in rural area fully utilize into renewable sources of energy technology, burn for solution the environmental pollution that brings and have opened up the clean energy resource new way, the extremely concern of business and government.No matter be to be fuel or generating or biochemical treatment with the straw regeneration and granulation, all need straw crushing to the length below 10cm, tradition adopts high speed centrifugation to beat stranding formula disintegrating apparatus crushed straw, adopt built-in getting rid of to beat the formula cutter and under the high speed centrifugation of 1800 rev/mins rotation, straw is beaten to rub with the hands and realize pulverizing, its rotating speed requires high, need to be equipped with heavy-duty motor, energy consumption is high; Cutter is beaten at a high speed the stranding easy damaged, improves use cost; The equipment middle cutter that runs up easily throws away, and has potential safety hazard; Straw is beaten at a high speed stranding, and in using area, dust is large, and contaminated environment affects operator ' s health.
Existing straw crushing equipment adopts the structure of similar garbage pulverator, by interlaced knife cut crushed straw on two parallel main shafts, to satisfy the slow-speed of revolution, low energy consumption, low cost, the requirements such as non-environmental-pollution and potential safety hazard.Pulverize by straw Disintegrating knife on cutter shaft between existing pulverizer cutting tool two parallel main axis, there is varicose power between two main shafts, long-term work easily makes two main shaft generation varicose distortion, thereby affects the knife cut performance on it, affects straw subsequent applications performance.
Summary of the invention
In order to solve deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and can effectively solve the varicose power between the crushing knife axle, extends the service life of pulverizing with axle, satisfies and pulverize the stalk crusher cutting tool varicose protective device that requires.
The technical solution adopted in the utility model is: a kind of stalk crusher cutting tool varicose protective device, it is characterized in that: comprise cutting tool and varicose protector, cutting tool comprises two cutter shafts and multi-disc Disintegrating knife, the corresponding multi-disc Disintegrating knife that is provided with interlaced distribution on two cutter shafts, described arbitrary cutter shaft external connection power input; The varicose protector is a connecting plate with two through hole, and two cutter shafts are connected in two through hole respectively.
Described connecting plate is connected in two cutter shaft middle parts.
Compared with prior art, advantage of the present invention is: socket varicose protector connecting plate on two cutter shafts of cutting tool, when passing through straw crushing for a long time between two cutter shafts, two cutter shafts are played the varicose protection, and avoid cutter shaft varicose distortion, increase the service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 top view.
In figure: crushing bin 1, active cutter shaft 2, from movable arbor 3, Disintegrating knife 4, connecting plate 5 picks tooth axle 6, picks teeth cutter blade 7, tripper 8.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, a kind of embodiment of stalk crusher cutting tool varicose protective device shown in 2, one group of above cutting tool is located in crushing bin 1, cutting tool comprises that socket initiatively respectively, the active cutter shaft 2 of driven gear, from movable arbor 3 and multi-disc Disintegrating knife 4, active cutter shaft 2, from movable arbor 3 respectively in the bearing horizontal parallel is supported on crushing bin 1, active cutter shaft 2, the corresponding multi-disc Disintegrating knife 4 that is provided with interlaced distribution from the movable arbor 3, multi-disc Disintegrating knife 4 is on cutter shaft along cutter shaft axial screw line to be installed, the initiatively external hydraulic power of cutter shaft 2 or electric power input, be used on crushing bin 1 supporting initiatively cutter shaft 2, form from the bulkhead of the movable arbor 3 upper and lower bulkhead by stepped cooperation, two cutter shafts are supported on respectively on the hierarchic structure that is in differing heights on lower bulkhead, Disintegrating knife 4 is the hook tooth blade with relief angle, initiatively cutter shaft 2, be socketed with the varicose protector from movable arbor 3, the varicose protector is a connecting plate 5 with two through hole, initiatively cutter shaft 2, from movable arbor 3 respectively gapless be connected in the two through hole of connecting plate, also be provided with below every group of cutting tool and pick tooth axle 6, pick tooth axle 6 in the crushing bin 1 of bearing horizontal parallel below cutter shaft is supported on cutter shaft, pick cross-under on tooth axle 6 have Disintegrating knife 4 on multi-disc and cutter shaft be gapless staggered pick teeth cutter blade 7, pick the external hydraulic power of tooth axle 6 or electric power input and rotation direction opposite with described cutter shaft rotation direction, also be provided with a tripper 8 above two cutter shaft intervening portions of every group of cutting tool.When in broken storehouse, charging is pulverized, by many groups cutting tool, straw is pulverized, the protector of varicose simultaneously carries out the varicose protection, picks the tooth axle and pick tooth and reject residual straw between the interlaced Disintegrating knife of cutting tool two cutter shafts of cutting tool.
