TECHNICAL FIELD
The present disclosure relates to a work machine, in particular to a crawler cleaning device for a work machine which comprises various construction machinery with a crawler, such as an excavator, a bulldozer for waste handling, and etc.
BACKGROUND Generally, the work machine operates in a relatively severe work environment. For example, a bulldozer for waste handling is used to work in a wasteyard, thus there are always various waste adhered to the crawler of the bulldozer. The waste may adhere to the crawler due to the slits inherent in the crawler, thereby on one hand directly damaging the crawler and on the other hand having an adverse impact on the operation of the bulldozer for waste handling.
For this purpose, conventionally, the bulldozer for waste handling is generally provided with a device for cleaning the crawler. Said device is able to improve the service life of the crawler and to make the operation of the bulldozer safe and reliable.
However, the above-mentioned crawler cleaning device is generally of an integral type, which is bulky and heavy, and has a complex structure and a high manufacturing cost. Particularly, it will affect the normal operation of the power take off (PTO) on the rear axle case body of the bulldozer for waste handling.
SUMMARY OF THE DISCLOSURE
In view of the above, the task of the present disclosure is to provide a crawler cleaning device for a work machine. Said crawler cleaning device is of a split type, which has a simple structure, a low manufacturing cost (material saving), a relatively low weight and occupies smaller room, and additionally will not affect the normal operation of the power take off (PTO) on the rear axle case body. Meanwhile, said crawler cleaning device may make use of the mounting position on the rear axle case body of the work machine (e.g. a bulldozer for waste handling) when being mounted, thus it is convenient to mount and maintain.
To accomplish the above-mentioned task, this disclosure provides a work machine, comprising crawlers, a rear axle case body and a crawler cleaning device secured on the rear axle case body, characterized in that the crawler cleaning device extends laterally from its secured portion towards the crawlers on both sides of the work machine in a split manner respectively. Preferably, a power take off is also mounted on the rear axle case body, such that the crawler cleaning device extends on the two sides of the power take off towards the crawlers respectively. Preferably, the crawler cleaning device consists of two parts which have the same structure and are symmetrical to each other with respect to the longitudinal central axis of the work machine.
The crawler cleaning device of the present disclosure, as compared with the crawler cleaning device in the prior art that is formed integrally, is favorable in respect of lowered cost (due to saving material), simplified structure and reduced weight.
Preferably, the crawler cleaning device is removably mounted on the rear axle case body via a screwed member.
In the present disclosure, when being removably mounted on the rear axle case body via a screwed member, the crawler cleaning device may be mounted by using the mounting position on the rear axle case body. Moreover, the crawler cleaning device is very convenient to mount and maintain because of its simple structure and low weight.
Preferably, the crawler cleaning device includes a pedestal mounted on the rear axle case body and a strike bar extends from the pedestal and finally to the crawler in the transverse direction of the longitudinal central axis of the work machine, wherein the strike bar is at least partially overlapped with the crawler in the transverse direction but spaced at a certain distance away from the crawler, so as to effect the cleaning.
According to this structure, the crawler cleaning device of the present disclosure, along with the traveling of the work machine, is able to act on various waste adhered to the crawler through the strike bar which extends along the transverse direction of the longitudinal central axis of the work machine, thereby to remove the waste.
Preferably, the crawler cleaning device of the present disclosure further includes a reinforcement plate coupled to the pedestal and the strike bar. Preferably, a section of the strike bar, which is adjacent to the pedestal, has a slit opened to the pedestal, and the reinforcement plate partially passes through the slit and then is coupled to the strike bar and pedestal by welding. As mentioned above, for forming the crawler cleaning device, the reinforcement plate partially passes through the slit and then is coupled to the strike bar and the pedestal by welding, so as to increase the strength of the strike bar and the entire crawler cleaning device.
Preferably, the reinforcement plate extends at least on one side along the entire length of the strike bar. For example, the reinforcement plate extends on the side facing the crawler along the entire length of the strike bar.
According to this structure, the reinforcement plate of the crawler cleaning device, together with the strike bar, is able to act on the waste adhered to the crawler, thereby to remove the waste. As mentioned above, the crawler cleaning device is arranged in a split type to leave sufficient room on the rear axle case body of the work machine for placing the PTO, so that the crawler cleaning device will not obstruct the normal operation of the PTO. In addition, the crawler cleaning device may use the mounting position on the rear axle case body of the work machine when being mounted, thus it is very convenient to mount and maintain.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig.1 shows a work machine with a crawler cleaning device according to the present disclosure; Fig.2 is a front view of the work machine with a crawler cleaning device of Fig.1 ; and
Fig.3 is a left view of the work machine with a crawler cleaning device of Fig.2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The preferred embodiments of the present disclosure will now be described with reference to Figs.1 to 3.
As shown in Fig.1 , a crawler cleaning device according to the present disclosure is mounted on a rear axle case body 6 of a work machine such as a bulldozer for waste handling via a screwed member (e.g. a bolt and a nut). There may be, but not limited to, three pairs of bolts and nuts used in the present embodiment. It is to be pointed out that, the crawler cleaning device of the present disclosure may use the mounting position on the rear axle case body 6 when being mounted, and additionally it has a simple structure, thus it is very convenient to mount and maintain.
Furthermore, different from the crawler cleaning device in the prior art that has an integral structure, the crawler cleaning device of the present disclosure is of a split type and consists of two parts, which extend on the two sides of a PTO 4 arranged on the rear axle case body 6 towards the crawlers 5 respectively. In addition, the two parts have completely the same structure and are symmetrical to each other with respect to the longitudinal central axis of the work machine, so as to be adapted for the two crawlers 5 of the work machine.
Each part of the crawler cleaning device includes a pedestal 1 mounted on the rear axle case body, and a strike bar 2 which extends from the pedestal 1 and finally to the crawler 5 in the transverse direction of the longitudinal central axis of the work machine. It is to be noted that, the strike bar 2 is at least partially overlapped with the crawler 5 in the transverse direction and spaced at a certain distance away from the crawler 5. As a result, when the work machine is traveling, the strike bar 2, along with the rotation of the crawler 5, is able to act on the waste adhered to the crawler 5.
The pedestal 1 may be of any shape and structure, as long as the pedestal 1 and the crawler cleaning device including the pedestal 1 would not obstruct the PTO 4 on the rear axle case body 6. As shown in Figs.1-3, the pedestal 1 has the shape formed by cutting one angle off from a rectangle, and the formed cuts of the two pedestals face towards the substantially central portion of the rear axle case body 6 (i.e. the two parts of the crawler cleaning device are arranged at the two upper angle portions of the rear axle case body 6 respectively), so that there is sufficient room left in the substantially central portion of the rear axle 6 for the arrangement of the PTO. In such a way, the mounting position of the pedestal 1 will not obstruct the normal operation of the PTO 4.
To increase the strength of the strike bar 2 and the crawler cleaning device, a reinforcement plate 3 is provided on the pedestal 1 and the strike bar 2. Generally, the reinforcement plate 3 is arranged on the pedestal and on one side of the strike bar by welding or the like. The reinforcement plate 3 may be arranged on at least one side of the strike bar 2 and extend along the entire length of the strike bar 2. In this embodiment, preferably, a section of the strike bar 2, which is adjacent to the pedestal 1 , has a slit 7 opened to the pedestal 1. The reinforcement plate 3 partially passes through the slit 7 and then is secured to the strike bar 2 and the pedestal 1 by welding.
It is to be noted that, the reinforcement plate 3, other than reinforcing the strike bar 2, is able to, together with the strike bar 2, act on the waste adhered to the crawlers 5, thereby to remove the waste.
In the present disclosure, the size and shape of the strike bar 2 and the reinforcement plate 3 may be designed according to the practical need, so that the formed crawler cleaning device has a relatively high strength and operation efficiency, thereby removes the waste adhered to the crawlers 5 effectively. For example, in this embodiment, the section of the strike bar 2, which is adjacent to the pedestal 1 , is, but not limited to, a trapezoid. Moreover, the distance between the strike bar 2 and the crawler 5 may also be designed according to the practical need. In addition, the crawler cleaning device in the above-mentioned embodiment is mounted on the rear axle case body 6 of the work machine. In fact, it may be mounted at other positions, e.g. on the front portion of the work machine.
During the practical operation, the strike bar 2 (together with the reinforcement plate 3), along with the traveling of the work machine and the rotation of the crawler 5, removes the articles, such as waste, adhered to the crawler 5, so as to make the operation of the work machine more secure and reliable, and to prolong the service life of the crawler 5.
