(57) [Summary] [Purpose] To improve the appearance of construction machinery and to prevent breakdowns due to entrainment of earth and sand. [Structure] The upper and side parts of the crawler 6 are covered with a crawler cover 7. Earth removal plates 8 and 9 are provided at the front and rear ends of the crawler cover 7 to scrape off dirt and the like adhering to the crawler 6.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to construction machinery equipped with a crawler in the traveling device, and in particular , relates to a cover that covers a crawler.

0002

[Conventional technology]

Construction machinery such as power shovels and bulldozers are equipped with crawlers on their traveling devices. There are many. This type of crawler is installed exposed on the fuselage.

0003

[Problem that the idea aims to solve]

Conventional construction machinery is installed with the crawler exposed, causing it to become contaminated with dirt and sand. Crawlers spoil the aesthetics and give a bad impression to the outside, and the rotation of the crawlers also This may cause dirt, etc. to enter the frame or rollers, causing a malfunction. Also, Ki When getting on and off the cabin, the operator may put his or her feet on the crawler. If you miss your step, there is a risk of injury from the sharp edges of the crawler.

0004 Therefore, we aim to improve the aesthetic appearance of construction machinery and prevent breakdowns caused by dirt and sand. However, there are technical issues that need to be resolved to ensure operator safety. The present invention aims to solve this problem.

[0005]

[Means to solve the problem]

This idea was proposed in order to achieve the above purpose, and it includes a clock on the traveling device. In a construction machine equipped with a crawler, the top and sides of the crawler are covered, and A soil removal plate is provided at the front and rear ends thereof, which is inclined with respect to the traveling direction of the crawler. The present invention provides a crawler cover for construction machinery with the following characteristics.

[0006]

[Effect]

This idea covers the top and sides of the crawler with a crawler cover, so The exposed part of the crawler is reduced and the appearance is improved. Also, the front and rear ends of the crawler cover A soil removal plate is provided at the crawler, and the soil removal plate is installed diagonally with respect to the direction of travel of the crawler. Therefore, the earth and sand attached to the crawler are discharged toward the outside of the aircraft by the soil removal plate. , it is possible to prevent the entrainment of earth and sand, etc.

[0007]

【Example】

An embodiment of this invention will be described below in detail with reference to the drawings. Figures 1 and 2 are construction machines A power shovel is shown as an example of a machine, with a lower frame at the bottom of the machine 1. A drive wheel 4 and a drive wheel 4 are installed by fixing side frames 3, 3 on both the left and right sides of the frame 2. A driving wheel 5 is attached and a crawler 6 is wrapped around it to form a traveling device.

[0008] Furthermore, the crawler cover 7 is fixed to the side frame 3. The crawler cover -7 covers the top and sides of the upper crawler 6a, and covers the exposed portion of the crawler 6. is decreasing. The crawler cover 7 will be explained with reference to FIG. Earth removal plates 8, 8 and 9, 9 are fixed to the front and rear ends of the top and side surfaces of the roller cover 7, respectively. do.

[0009] The earth removal plate 8 is installed obliquely with respect to the traveling direction of the upper crawler 6a, and The earth removal plates 8, 8 are inclined so that the distance between them gradually decreases toward the outside of the fuselage 1. or The upper edge of the earth removal plate 8 is rounded with appropriate dimensions. On the other hand, the earth removal plate 9 is is inserted into the lower surface of the crawler 6a on the side, and the It is inclined at approximately the same angle as the earth removal plate 8. That is, the crawler 6a on the upper side It is in a state where it is narrowly inserted between the earth removal plate 9 and the soil removal plate 9 with a certain gap.

0010 Therefore, when the traveling device is driven to make the aircraft 1 travel, the crawler 6 rotates. It moves to the upper crawler 6a with dirt, pebbles, etc. on the ground attached, but the crawler The earth and sand adhering to the upper surface of the roller 6a are scraped off by the earth removal plate 8. mentioned above As described above, the upper edge of the earth removal plate 8 is rounded, and the crawler 6a Since the crawler 6a is inclined with respect to the traveling direction of the crawler 6a, the scraped earth and sand are As it advances, it gradually moves to the outside of the aircraft 1 and is ejected from the outer end of the crawler 6a to the ground. Served.

[0011] On the other hand, earth and sand adhering to the lower surface of the upper crawler 6a are scraped by the earth removal plate 9. be dropped. Since the earth removal plate 9 is also inclined with respect to the traveling direction of the crawler 6a, The scraped earth and sand are discharged from the crawler cover 7 to the ground. Also, chloraka The bar 7 covers the upper and side parts of the upper crawler 6a, and the front Since the crawler 6a is narrowly inserted between the soil removal plates 8 and 9, the crawler 6a This prevents dirt, pebbles, etc. thrown up by the air from entering the inside of the side frame 3. Wear. In addition, if a rubber scraper is attached to the soil removal plates 8 and 9, the soil removal plates 8 and 9 can be Therefore, the soil removal performance of the roller 6a can be further improved.

0012 Here, as shown in FIGS. 1 and 3, a foldable stand is installed on the side of the crawler cover 7. 10, 10 may also be provided. This step 10 usually It does not protrude outward from the side surface of the bar 7 and is held flush with the side surface. And the operation When you get on and off, push the lever in with your foot, and the weight of your foot will cause it to tilt inward, making it easy to use for going up and down. Acts as a step. When the operator's feet are removed, the spring, etc. By this means, the step 10 is returned to its original state.

[0013] Although not shown, the upper part of the crawler cover 7 can be slid outwardly. , it can also be made compatible with the installation of wide crawlers. Furthermore, Ku The sides of the roller cover 7 can be opened and closed freely, improving the maintainability of the inside of the crawler cover 7. It is possible to make various modifications such as Of course.

[0014]

[Effect of the idea]

As detailed in the above embodiment, this invention has a crawler cover attached. Exposed parts of the crawler are reduced, improving external appearance. The crawler cover has no exhaust gas. A clay plate is installed to prevent dirt, etc. attached to the crawler from entering the inside of the frame. It can be prevented. Furthermore, there is a risk of injury from exposed parts of the crawler when the operator gets on and off the machine. This can contribute to improving safety.
