Description

Technical Field

[0001] The utility model relates to a crawler guide rail which is resistant to breakage, belonging to the technical field of agricultural machinery accessories. Background Art

[0002] The crawler of a harvester is an important component of the harvester. The crawler is driven by a main driving wheel. To use the crawler, a guiding rail must be installed on the machine. The guiding rail is fixed in the crawler guiding groove and is fixedly connected to the machine chassis through screws. During the running of the harvester, the existing crawler guiding rail often causes wear of the iron teeth of the crawler guiding groove by the guiding rail, and frequent breakage of the fixing screws of the guiding rail, resulting in derailment and damage to the crawler. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a crawler guide rail which is resistant to breakage, safe and reliable, not easy to break, not easy to break screws, and not easy to wear the iron teeth of the crawler guiding groove.

[0004] In order to achieve the above-mentioned utility model purpose, the technical solution adopted by the utility model is as follows: A crawler guide rail which is resistant to breakage includes a guiding bottom plate placed in the crawler guiding groove. An installation seat for connecting with the machine chassis is arranged on the guiding bottom plate. A screw fixing hole is arranged on the installation seat. A screw is also provided. The screw passes through the screw fixing hole and is screwed and tightened into the screw hole on the machine chassis, so that the guiding bottom plate is fixed to the machine chassis;

[0005] Both sides in the length direction of the guiding bottom plate are inclined planes. When the guiding bottom plate is placed in the crawler guiding groove, both sides in the length direction of the guiding bottom plate are respectively parallel to the two inner side surfaces in the length direction of the corresponding crawler guiding groove. Its characteristics are:

[0006] Reinforcing ribs are arranged on both sides in the length direction of the guiding bottom plate, and the reinforcing ribs are arranged along the length direction of the guiding bottom plate;

[0007] An impact buffer spacer is arranged in the screw fixing hole, and the impact buffer spacer is located inside the screw fixing hole. The screw passes through the impact buffer spacer in the screw fixing hole and is screwed and tightened into the screw hole on the machine chassis. When the screw passes through the screw fixing hole, the screw is supported on the impact buffer spacer in the screw fixing hole.

[0008] The impact buffer spacer is located in the lower half section of the screw fixing hole.

[0009] The reinforcing rib is a concave steel structure.

[0010] The number of the installation seats is one or more, and one or several installation seats are installed on the guiding bottom plate.

[0011] On both sides of the guiding bottom plate in the length direction, the inclined planes are respectively the guiding bottom plate side A and the guiding bottom plate side B, and on both inner sides of the crawler guiding groove in the length direction are respectively the crawler guiding groove iron tooth inner side A and the crawler guiding groove iron tooth inner side B; the guiding bottom plate side A of the guiding bottom plate is parallel to the crawler guiding groove iron tooth inner side A, and the guiding bottom plate side B of the guiding bottom plate is parallel to the crawler guiding groove iron tooth inner side B.

[0012] Both sides of the bottom of the guiding bottom plate are chamfered.

[0013] Both the front and rear ends of the guiding bottom plate are upturned.

[0014] The hardness of the impact buffering spacer is lower than that of the mounting seat.

[0015] On both sides of the impact buffering spacer extending out of the screw fixing holes, there are flanges, and the flanges are attached to the mounting seat.

[0016] On both sides of the mounting seat, there are flange grooves, and the flanges on both sides of the impact buffering spacer extending out of the screw fixing holes are placed and attached in the corresponding flange grooves.

[0017] On both sides of the guiding bottom plate, there are respectively a plurality of mounting holes, and solid lubricants are respectively inlaid in the mounting holes.

[0018] The structure of the utility model is reasonable and simple, easy to manufacture and convenient to use. Through the utility model, a crawler guide rail that prevents breakage is provided. Structurally, it includes a guiding bottom plate placed in the crawler guiding groove, and one to several mounting seats are arranged on the guiding bottom plate. The contact surfaces on both sides of the guiding bottom plate are integral inclined planes and are parallel to the inner side of the crawler guiding groove, and both sides of the bottom of the guiding bottom plate are chamfered.

[0019] Among them, the mounting seat includes one to several screw fixing holes, and an impact buffering layer is arranged in the lower half of the screw fixing holes. The impact buffering layer of the mounting seat can be composed of various materials, and its hardness should be lower than that of the mounting seat itself. Both the front and rear ends of the guiding bottom plate are upturned.

[0020] Through the utility model, most of the problems that may occur in the crawler guide rail during years of actual use are solved. Specifically:

[0021] 1. To solve the problem that the guide rail often breaks during operation in high-temperature and drought in summer or in hard mountainous areas.

[0022] Two reinforcing ribs running through the entire guide rail are added to the upper plane of the guide rail bottom plate, forming a concave shape when viewed from the cross-section. Greatly increasing the impact resistance of the guide rail under impact and other conditions. The concave steel structure is not easy to deform and break during long-term use. The broken guide rail will seriously damage the crawler of the harvester. The situation where the crawler is damaged due to the breakage of the guide rail is very common every year, and the cost is high.

[0023] 2. In years of use, it has been found that the guide rail screws often break, so that each harvester has formed the habit of keeping spare guide rail screws. Through long-term observation and experiments, the breakage of the guide rail screws is mainly because when the guide rail crosses ditches or uneven plots during operation, the guide rail makes an impact and then instantly moves upward. The fixed screw of the guide rail hits the lower side wall of the mounting hole of the guide rail seat, forming a cutting effect. To reduce the breakage of the guide rail screws, we set impact buffer spacers in the lower half of the screw holes of the guide rail mounting seat. The spacers can be made of rubber. After adding the buffer spacers, the direct hard collision between the screw and the mounting hole of the guide rail seat becomes a relatively gentle soft contact, greatly reducing the breakage of the screws.

[0024] 3. It has also been found in long-term use that when new guide rails and new crawler belts are just installed, the friction during the running-in period is relatively large, and the wear of the iron teeth of the crawler belt is mainly concentrated in this stage. To solve this problem, we set multiple mounting holes on both sides of the guide rail, and layered solid lubricants (such as graphite blocks, molybdenum disulfide, etc.) are inlaid in the mounting holes respectively. In the initial installation stage, with the operation of the guide rail, it is gradually released after friction and coats the guide rail and the iron teeth of the crawler belt. Greatly reduce the dynamic friction between the guide rail and the iron teeth of the crawler belt during the running-in period, and reduce the wear of the crawler belt and the guide rail.

[0025] Through the present utility model, the anti-breakage crawler guide rail is safe and reliable, not easy to break, and not easy to break the screws, and has great market application and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
