Description

Technical Field

[0001] The utility model belongs to the technical field of crawlers, and in particular relates to a self-cleaning crawler, a crawler wheel assembly, a crawler wheel chassis and a crawler-type agricultural machine. Background Art

[0002] At present, there are mainly two types of large-scale agricultural machinery: rubber tracked agricultural machinery and wheeled agricultural machinery. Tracked agricultural machinery has the advantages of low ground contact pressure and good soil protection performance. It can also improve the passability of agricultural machinery. In addition, compared with traditional metal tracks, rubber tracks cause less damage to hardened roads. However, the gaps between the patterns of rubber tracks are easily filled with mud, which will increase the slip rate of the track system, reduce traction, and increase fuel consumption. Utility Model Content

[0003] In order to solve the above technical problems, one of the objectives of the present invention is to provide a self-cleaning crawler with a simple structure and in which mud is not easily adhered between the main ridges.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a self-cleaning track, comprising a track body made of rubber material, wherein the outer side of the track body is provided with strip-shaped main ridges at intervals along the circumferential direction, and secondary ridges are provided between two adjacent main ridges.

[0005] The beneficial effect of the above technical solution is that when the crawler body bends at the position of the guide wheel, the space between two adjacent main ridges is opened, thereby loosening the mud mass between the two, and finally the loosened mud mass is squeezed out by the secondary ridges and falls off under the action of its own weight.

[0006] In the above technical solution, two groups of main ridge groups are arranged on the outer side of the track body, which are spaced apart along the width direction of the track body. Each group of the main ridge groups has multiple main ridges spaced apart along the circumferential direction of the track body, and the secondary ridges are arranged between two adjacent main ridges in the main ridge group.

[0007] The beneficial effect of the above technical solution is that it makes the track body more passable on the ground.

[0008] In the above technical solution, the plurality of main ridges in the two groups of main ridges are distributed in an alternating manner.

[0009] The beneficial effect of the above technical solution is that it makes the anti-skid performance of the crawler track better.

[0010] In the above technical solution, the main ridges are arranged obliquely along the width direction of the track body.

[0011] The beneficial effect of the above technical solution is that it can further improve the anti-skid performance of the crawler track, and at the same time make it easier for the mud balls between two adjacent main ridges to fall off after being loosened.

[0012] In the above technical solution, the angle between two adjacent main ridges in the width direction of the track body is an obtuse angle.

[0013] The beneficial effect of the above technical solution is that it can further improve the anti-skid performance of the crawler track.

[0014] In the above technical solution, the side of the secondary ridge facing away from the crawler body has a sharp corner or edge.

[0015] The beneficial effect of the above technical solution is that the corners and edges of the secondary ridges facing away from the track body can crush the mud clumps adhering between the corresponding two primary ridges until they are separated.

[0016] The surface of the secondary convex pattern in the above technical solution is provided with a low-adhesion layer.

[0017] The beneficial effect of the above technical solution is that the adhesion between the auxiliary convex patterns and the mud balls is reduced, so that the mud balls can be dropped more easily.

[0018] The second purpose of the present utility model is to provide a track wheel assembly which has a simple structure and can automatically clean mud clumps between the main ridges on the track.

[0019] In order to achieve the above-mentioned purpose, another technical solution of the present invention is as follows: a track wheel assembly, comprising the self-cleaning track as described above.

[0020] The beneficial effects of the above technical solution are: its structure is simple, and its crawler track can be self-cleaned during field operations, thereby improving the operating efficiency of the entire crawler wheel assembly.

[0021] The third purpose of the present invention is to provide a crawler wheel chassis with a simple structure and high operating efficiency.

[0022] In order to achieve the above-mentioned purpose, another technical solution of the present invention is as follows: a track wheel chassis, comprising the track wheel assembly as described above.

[0023] The beneficial effects of the above technical solution are: its structure is simple, and its crawler can automatically clean mud clumps between the main ridges when working in the field.

[0024] A fourth object of the present invention is to provide a crawler-type agricultural machine with a simple structure and high operating efficiency.

[0025] In order to achieve the above-mentioned purpose, another technical solution of the present invention is as follows: a crawler-type agricultural machine includes the crawler wheel chassis as described above.

[0026] The beneficial effects of the above technical solution are: low energy consumption and high operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown, this embodiment provides a self-cleaning track, including a track body 1 made of rubber material, the outer side of the track body 1 is provided with strip-shaped main ridges 2 at intervals along the circumferential direction, and secondary ridges 3 are provided between two adjacent main ridges 2, so that when the track body is bent at the position of the guide wheel, the space between the two adjacent main ridges is opened, thereby loosening the mud mass between the two, and finally squeezing the loosened mud mass out by the secondary ridges and falling off under the action of its own weight.

[0034] in, Figure 1 The front-to-back direction is the length direction of the crawler body, and the left-to-right direction is the width direction of the crawler body.

[0035] Specifically, in the above technical solution, the outer side of the track body 1 is provided with two groups of main ridge groups 20 distributed at intervals along the wide direction of the track body 1, each group of the main ridge groups 20 has a plurality of main ridges 2 distributed at intervals along the circumferential direction of the track body 1, and the auxiliary ridges 3 are provided between two adjacent main ridges 2 in the main ridge group 20, so that the passability of the track body and the ground is better; the multiple main ridges 2 in the two groups of the main ridge groups 20 are staggered, so that the anti-skid performance of the track is better; the main ridges 2 are inclined along the wide direction of the track body 1, which can further improve the anti-skid performance of the track and make it easier for mud balls between two adjacent main ridges to fall off after loosening; the angle between two adjacent main ridges 2 in the wide direction of the track body 1 is an obtuse angle (specifically, it can be any value among 120°, 140° and 160° or the corresponding range between any two values), so that the anti-skid performance of the track can be further improved.

[0036] like Figure 1-Figure 3 As shown, in the above technical solution, the side of the secondary ridge 3 facing away from the track body 1 has corners or edges, so that the corners or edges of the secondary ridge facing away from the track body can crush the mud clumps adhered between the corresponding two main ridges until they are separated.

[0037] Specifically, such as Figure 3 As shown, the secondary ridges include two triangles along the length of the main ridges, and one edge of each triangle faces away from the track body. Preferably, the two triangles are a first triangle 32 and a second triangle 33. The first triangle 32 can be an isosceles triangle, and its bottom side is connected to the track body, while the second triangle 33 can be a right-angled triangle, and one straight side is connected to the track body, and the other straight side is close to the first triangle. At this time, the edges of the two triangles facing away from the track body are used to crush mud balls (especially at the position of the guide wheel, when the two adjacent main ridges are unfolded, the secondary ridges have a better crushing effect on the mud balls).

[0038] like Figure 3 As shown, the surface of the secondary convex pattern 3 in the above technical solution is provided with a low-adhesion layer 31 (that is, the surfaces of the first triangle and the second triangle are both provided with a low-adhesion layer 31), so that the adhesion between the secondary convex pattern and the mud ball is small, so that the mud ball can fall off more easily.

[0039] in, Figure 3 The middle is along Figure 1 Cross-sectional view taken along the dashed line K.

[0040] The low adhesion layer 31 described in the above technical solution is a low-viscosity rubber (specifically, it can be similar to the surface rubber material disclosed in document No. CN108948508B "A material for improving the service life of rubber track pattern surface rubber and its preparation method"), which has good durability.

[0041] Example 2

[0042] This embodiment provides a track wheel assembly, including the self-cleaning track as described in Example 1. It has a simple structure, and its track can perform self-cleaning during field operations to improve the operating efficiency of the entire track wheel assembly.

[0043] Example 3

[0044] This embodiment provides a track wheel chassis, including the track wheel assembly as described in Example 2, which has a simple structure and its track can automatically clean mud clumps between the main ridges when working in the field.

[0045] Example 4

[0046] This embodiment provides a crawler-type agricultural machine (which may be a harvester), including the crawler wheel chassis as described in Example 3, which has low energy consumption and high operating efficiency.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
