Abstract
The utility model which relates to a harrowing gear fixation structure of a screen scarifier mining chain comprises a cylinder pin (3), a gear sleeve (4) and a harrowing gear (1) which passes through an axial hole of a harrowing plate (2), and the gear sleeve (4) is sleeved on the axis of the harrowing gear (1), and the cylinder pin (3) which passes through an axis of the gear sleeve (4) and the harrowing gear (1) connects the gear sleeve (4) and the harrowing gear (1) together, and the utility model is characterized in that the external round of the gear sleeve (4) is provided with a ring-shaped groove (4-1), and a steel wire shield ring (5) is arranged in a ring-shaped groove (4-1). The utility model which can guarantee the using requirements of the harrowing gear is both easy for assembly and disassembly and is convenient in replacing the harrowing gear.
Description
Technical field
The utility model relates to railway track maintenance and service equipment-railway roadbed cleaning mechine field, specifically, relates to a kind of screen scarifier digger chain rake teeth fixed structure.
Background technology
Ballast cleaning machine is to be used for the Work machine of ballast aggregate in the ballast cleaning, the RM80 type that mainly contains, QQS300 type, QQS500 type that China uses now, and below narration is an example with the RM80 type all.It digs out dirty ballast aggregate under sleeper, after sieving, will clean ballast aggregate and be backfilled to railway roadbed, and the dirty soil that sieves out is scavenged into outside the circuit.Digger chain is one of main building block of screen scarifier excavating gear, and according to the difference of excavating width, digger chain is made up of 82 to 86 joints.
The digger chain rake teeth is installed in the axis hole of rake plate, and can freely rotate, and adopts gear ring and straight pin fastening.Directly contact during rake teeth work, be subjected to high-speed friction and impact with ballast, though make with the high-strength abrasion-proof material, but still need often to change.When rake teeth is changed at the scene, as shown in Figure 1, need straight pin be got, need squeeze into new straight pin during installation with special punch.Because the straight pin head has distortion when squeezing into, the very difficulty that becomes when getting has to gas cutting rake teeth be sliced off sometimes, and is very time-consuming when therefore changing rake teeth, and causes the part waste.
Summary of the invention
The purpose of this utility model provides a kind of instructions for use that can guarantee rake teeth, is convenient to the screen scarifier digger chain rake teeth fixed structure that mounts and dismounts again.
The technical scheme that realizes above-mentioned purpose is: a kind of screen scarifier digger chain rake teeth fixed structure, comprise straight pin, tooth cover and the rake teeth that passes rake plate axis hole, the tooth cover is sleeved on the axle of rake teeth, straight pin passes the axle of tooth cover and rake teeth, and tooth cover and rake teeth linked together, have annular groove on the cylindrical of tooth cover, elastic spring is housed in the annular groove.
After adopting technique scheme, when needing to change rake teeth,, the elastic spring in the annular groove is prized as long as screwdriver is inserted in the cylinder pin hole place with one, rotate rake teeth, make straight pin keep the upright position, straight pin drops out automatically, takes off tooth cover and rake teeth, therefore dismantle very convenient, need not special-purpose instrument, and except that rake teeth, other part can be reused.

Fig. 2 is the schematic diagram of the utility model screen scarifier digger chain rake teeth fixed structure;
Fig. 3 is the sectional structure schematic diagram of tooth cover among Fig. 2;
Fig. 4 is the left view of Fig. 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 2,3,4, a kind of screen scarifier digger chain rake teeth fixed structure, comprise straight pin 3, tooth cover 4 and the rake teeth 1 that passes rake plate 2 axis holes, tooth cover 4 is sleeved on the axle of rake teeth 1, straight pin 3 passes the axle of tooth cover 4 and rake teeth 1, and tooth cover 4 and rake teeth 1 linked together, have annular groove 4-1 on the cylindrical of tooth cover 4, elastic spring 5 is housed in the annular groove 4-1.
Shown in Fig. 3,4, the outer face of tooth cover 4 and the intersection of cylindrical are processed with big chamfering 4-2.After adopting this structure, can easily elastic spring 5 be fit among the ring groove 4-1.
When the utility model is installed, rake teeth 1 is contained in the axis hole of rake plate 2 earlier, puts tooth cover 4, big chamfering 4-2 outwardly, aim at the pin-and-hole on the rake teeth 1, the straight pin 3 of packing into rotates rake teeth 1, make straight pin 3 keep horizontal level, at last elastic spring 5 is pushed in the annular annular groove 4-1, install.
During dismounting, with one screwdriver is inserted in place, straight pin 3 holes, the elastic spring in the annular groove 4-1 5 is prized, rotate rake teeth 1, make straight pin 3 keep the upright position, straight pin 3 drops out automatically, takes off tooth cover 4 and rake teeth 1, and dismounting finishes.
Claims (2)
1. screen scarifier digger chain rake teeth fixed structure, the rake teeth (1) that comprises straight pin (3), tooth cover (4) and pass rake plate (2) axis hole, tooth cover (4) is sleeved on the axle of rake teeth (1), straight pin (3) passes the axle of tooth cover (4) and rake teeth (1), and tooth cover (4) and rake teeth (1) linked together, it is characterized in that: have annular groove (4-1) on the cylindrical of tooth cover (4), elastic spring (5) is housed in the annular groove (4-1).
2. screen scarifier digger chain rake teeth fixed structure according to claim 1 is characterized in that: the outer face of tooth cover (4) and the intersection of cylindrical are processed with big chamfering (4-2).
