Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to an adaptive terrain track structure. Background Technology

[0002] A track is a flexible chain driven by a drive sprocket and surrounding the drive sprocket, road wheel, idler wheel, and track support roller. The track consists of track plates and track pins. The track pins connect the track plates to form the track chain. The track plates have holes at both ends that mesh with the drive sprocket, and guide teeth in the middle to straighten the track and prevent it from falling off when turning or tilting. The side in contact with the ground has reinforced anti-slip ribs to improve the strength of the track plates and the adhesion between the track and the ground.

[0003] Tracked structures have a wide range of applications. For example, in agricultural harvesting operations, agricultural products are often transported using tracked transport equipment. However, field terrain is often uneven. During the movement of traditional tracked transport equipment, the platform will tilt as the terrain changes, which may cause the items placed on it to fall off, affecting the efficiency of transportation and use, and thus has certain limitations.

[0006] Both ends of the middle beam are connected to a set of bushings. The middle outer end of the middle beam is provided with a set of outer sleeves. The inner left and right ends of the outer sleeves are connected to the two sets of bushings through auxiliary mechanisms. The top of the outer sleeve is connected to a set of horizontal support plates.

[0007] Preferably, the components of the two sets of bushings are identical. The right end of the bushing is provided with a set of mounting grooves.

The right end of the fixing flat washer is connected to a fixing nut. The right end of the intermediate beam extends through to the right end of the bushing and is connected to a fixing pin.

[0008] Preferably, all components of the auxiliary mechanism are identical. The auxiliary mechanism on the right end includes an annular groove, an external gear ring, gears, a synchronous shaft, a drive motor, and a protective sleeve. An annular groove is provided on the right end of the outer sleeve. A set of external gear rings is provided on the outer side of the middle beam at the position corresponding to the annular groove. A set of gears corresponding to the external gear rings is provided at the upper and lower ends of the annular groove. A set of synchronous shafts is connected to the middle right end of both sets of gears. The other end of the synchronous shafts extends to the left side of the right end sleeve. A set of drive motors is provided at the upper and lower ends of the right end sleeve. The right end of the drive shaft of the drive motor extends through to the outside of the sleeve and connects to the synchronous shaft. A set of protective sleeves is provided on the outside of the synchronous shaft.

[0024] Please see Figure 2 and 4This utility model provides an adaptive terrain track structure. The components of the auxiliary mechanism 22 are all identical. The right-end auxiliary mechanism 22 includes an annular groove 221, an external gear ring 222, a gear 223, a synchronous shaft 224, a drive motor 225, and a protective sleeve 226. An annular groove 221 is provided on the right end of the outer sleeve 23. A set of external gear rings 222 are embedded in the outer side of the middle beam 2 at positions corresponding to the annular groove 221. A set of gears 223 corresponding to the external gear rings 222 are provided at both the upper and lower ends of the annular groove 221.

[0025] The working principle is as follows:

[0026] In use, the left track assembly 1 and the right track assembly 3 drive the middle beam 2 and the items placed on the horizontal pallet 24 to move. When moving to terrain with a slope, one end of the left track assembly 1 and the right track assembly 3 tilts up. The drive motor 225 drives the gear 223 to rotate through the synchronous shaft 224. Through the meshing of the external gear ring 222 and the gear 223, the middle beam 2 rotates in the opposite direction. The two ends of the middle beam 2 rotate within the two sets of bushings 21, which keeps the horizontal pallet 24 in a horizontal state and prevents the items placed on the horizontal pallet 24 from tilting and falling.
