Description

Technical Field

[0001] The utility model relates to the technical field of rubber crawlers, and more specifically to a rubber crawler without iron teeth. Background Art

[0002] Iron-free rubber tracks are widely used in construction machinery, agricultural machinery and military equipment. Machinery equipped with iron-free rubber tracks has the advantages of low noise, low vibration and comfortable ride.

[0020] Some existing rubber tracks have rubber tread blocks on their outer surfaces to improve grip. However, on muddy roads with a lot of mud, the mud can easily adhere to and get stuck between the rubber tread blocks, reducing the friction between the rubber tread blocks and the road surface, thereby affecting the grip of the rubber track and making it prone to slipping. The following solution is used to solve this problem.

[0021] See also Figures 1 to 4 The rubber crawler without iron teeth comprises a crawler body 1, an inner guide rubber block 2 is fixedly connected to the inner surface of the crawler body 1, a rubber pattern block 3 is fixedly connected to the outer surface of the crawler body 1, a first mud cleaning piece 4 is arranged between two adjacent rubber pattern blocks 3, first grooves 5 are provided on both sides of the corresponding sides of the first mud cleaning piece 4, a first fixed shaft 6 is fixedly connected inside the first groove 5, a second mud cleaning piece 7 is sleeved outside the first fixed shaft 6, and the mud stuck between the two rubber pattern blocks 3 is cleared by the first mud cleaning piece 4 and the second mud cleaning piece 7. The soil is automatically cleaned to ensure the grip of the crawler body 1, the second mud cleaning piece 7 is rotatably connected to the first fixed shaft 6, a second groove 8 is provided on the side of the second mud cleaning piece 7 away from the first fixed shaft 6, the second groove 8 is fixedly connected to the second fixed shaft 9, a connecting piece 10 is sleeved on the outside of the second fixed shaft 9, the connecting piece 10 is rotatably connected to the second fixed shaft 9, the rubber pattern block 3 is fixedly connected to the connecting piece 10, and the rubber pattern block 3 and the second mud cleaning piece 7 are connected by the connecting piece 10 in cooperation with the second fixed shaft 9.

[0022] There are two second grooves 8 , which are symmetrically distributed. The two sets of second fixed shafts 9 and connecting pieces 10 can ensure the stability of the connection between the second mud clearing piece 7 and the rubber pattern block 3 to prevent separation.

[0023] The first mud cleaning piece 4 and the second mud cleaning piece 7 are both elastic, which can ensure the service life of the first mud cleaning piece 4 and the second mud cleaning piece 7, prevent the first mud cleaning piece 4 or the second mud cleaning piece 7 from bending, deforming or breaking, and ensure the effect of cleaning the mud.

[0024] The first mud cleaning sheet 4 and the second mud cleaning sheet 7 have the same thickness, so that the first mud cleaning sheet 4 and the second mud cleaning sheet 7 are more regular as a whole when unfolded, and there is no thickness difference between the first mud cleaning sheet 4 and the second mud cleaning sheet 7, and it is not easy to leave mud.

[0025] The length of the first mud cleaning piece 4 is greater than that of the second mud cleaning piece 7. The rubber pattern block 3 is close to a quadrangular pyramid structure as a whole. The side away from the track body 1 is small, which is the upper surface, and the side close to the track body 1, that is, the side connected to the track body 1, is large, which is the lower surface. The overall length of the second mud cleaning piece 7 is close to the length of the upper surface of the rubber pattern block 3, and the length of the first mud cleaning piece 4 is close to the length of the lower surface of the rubber pattern block 3. The shorter second mud cleaning piece 7 can ensure that it can be completely retracted into the position between the two rubber pattern blocks 3, and the longer first mud cleaning piece 4 can maximize the push away of the mud stuck between the two rubber pattern blocks 3, thereby improving the cleaning effect.

[0026] The use steps of the utility model are as follows: when the rubber track without iron teeth is in use, when the track body 1 walks on a muddy road with more mud, the rubber pattern blocks 3 on the outer surface of the track body 1 are in contact with the ground. As the track body 1 walks, the positions of the rubber pattern blocks 3 on the outer surface of the track body 1 are constantly changing. The distance between the rubber pattern blocks 3 above and below the track body 1 is the smallest. At this time, the first mud cleaning piece 4 and the second mud cleaning piece 7 are both retracted between two adjacent rubber pattern blocks 3, and the distance between the rubber pattern blocks 3 at both ends of the track body 1 becomes larger, which makes the two adjacent rubber pattern blocks 3 pull the first mud cleaning piece 4 through the second mud cleaning piece 7, so that the first mud cleaning piece 4 moves away from the track body 1, thereby being able to push away the mud stuck on the track body 1, thereby achieving the purpose of automatic cleaning and ensuring the gripping ability of the track body 1.
