Preferably, the self-cleaning block is vertically symmetrical about a horizontal axis X.

Preferably, the connection part of the self-cleaning block and the crawler body adopts fillet transition, and the radius of the fillet is more than 5 mm.

A second object of the present invention is to provide a crawler type traveling device, which comprises a chassis, a wheel system disposed on the chassis, and a crawler belt disposed around the wheel system, wherein the crawler belt adopts the above mud scraping crawler belt.

Preferably, a gap of 5-10mm is left between the self-cleaning block and the chassis.

To sum up, the utility model has the advantages that the inboard at the track body has set up the automatically cleaning piece to when making the track motion, the automatically cleaning piece can be cleared up the attachment on the chassis, prevents that the attachment from piling up, leads to the unable operation of machine.

Detailed Description

As shown in fig. 1 and 2, a crawler type traveling device comprises a chassis 1, wherein a wheel train is rotatably arranged on the chassis 1, and the wheel train specifically comprises a driving wheel 2 positioned on the left side of the chassis 1, a supporting wheel 5 positioned on the lower portion of the chassis 1, a tension wheel 7 positioned on the right side of the chassis 1, and a carrier roller 8 positioned on the upper portion of the chassis 1. The endless track is provided around the wheel train, and the endless track includes an endless track body 11, a core 12 is provided inside the track body 11, and the end of the core 12 constitutes a driving tooth 13 for connecting the driving wheel 2, so the core 12 needs to be arranged along the length direction of the endless track, and the core 12 needs to be arranged at the pitch of the driving wheel 2 so as to be engaged with the driving wheel 2. The flower blocks 14 are arranged on the outer side of the crawler body 11, the positions of the flower blocks 14 correspond to the core metal 12, and the flower blocks 14 are used for improving the ground holding force of the crawler when the crawler walks.

As mentioned in the background art, during the walking process of the crawler, the attachments 9 such as soil, weeds, rice straws and the like attached on the surface of the flower blocks 14 and the wheel system are thrown onto the chassis 1 of the machine along with the rotation of the crawler.

As shown in fig. 3 and 4, in order to automatically clean the attachments 9, the self-cleaning block 17 is disposed on the track, the self-cleaning block 17 may be disposed on a certain pitch of the track body 11, or on a plurality of pitches of the track body 11, and the specific number and position may be selected according to different use scenes. The specific location and configuration of the self-cleaning block 17 is as follows: the self-cleaning block 17 is positioned at the end, close to the chassis 1, of the inner side surface of the crawler body 11, the self-cleaning block 17 extends from the inner side of the crawler body 11 to the end part, and continues to extend upwards after reaching the end part to be connected with the flower block 14, and the connection strength of the self-cleaning block 17 is guaranteed. In order to ensure the cleaning effect, the shape of the self-cleaning block 17 is approximately adapted to the contour of the chassis 1, but a gap of 5-10mm is required between the self-cleaning block 17 and the chassis 1, so that the self-cleaning block 17 can normally pass through the chassis 1.

To further enhance cleaning, as shown in FIG. 4, self-cleaning block 17 is generally trapezoidal and generally vertically symmetrical about a transverse axis X. Wherein the base 171 of the trapezoid is wider and relatively near the center of the track body 11. The top edge 172 of the trapezoid is narrower and is located at the end of the track body 17. The included angle between the side 173 of the trapezoid and the longitudinal axis Y is 90-110 degrees, so that the attachments 9 can be discharged outwards along the side 173 of the trapezoid, and the attachments 9 are prevented from moving towards the inner end of the crawler body 11.

In order to further improve the cleaning capability, the junction of the self-cleaning block 17 and the track body 11 is in a fillet transition, the radius of the fillet should be larger than 5mm, the fillet transition has the function of avoiding the accumulation of the attachments 9 at the root of the self-cleaning block 17, and the fillet transition is added to facilitate the flowing of the attachments at the root position.

To sum up, the utility model has the advantages that the inboard at track body 11 has set up automatically cleaning piece 17 to when making the track motion, automatically cleaning piece 17 can clear up attachment 9 on the chassis 1, prevents that attachment 9 from piling up, leads to the unable operation of machine.
