Abstract

(57) [Summary] [Purpose] To prevent the paint on the exterior wall surface from peeling off due to heat. [Structure] A duct 9 is attached to the front wall 2, a partition plate 11 is attached inside the duct 9 to constitute an exhaust gas introduction part 12 and an outside air introduction part 13, and the exhaust gas introduction part 12 is connected to the exhaust gas intake case 10. , is opened to the front passage 6 to allow engine exhaust gas to flow through the front passage 6 and the side passages 8 to heat the body, and the outside air introducing portion 13 is opened to the outside air through the upper and lower holes 17 and 18 to allow the side wall 4 to allow cooling.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a boon for off-road dump trucks such as dump trucks for large construction machinery. Regarding Day.

0002

[Conventional technology]

Off-road dump trucks have a body mounted on the vehicle body that can be raised and lowered freely, and soil is stored inside the body. It is also possible to load and transport sand, etc., and then place the body in an upright position to discharge the sand, etc. inside the body. In order to prevent dirt from adhering to the inner wall surface of the body, A rib is provided on the bottom part to form a passage, and the exhaust gas from the engine is circulated through the passage. Heating the day.

0003

[Problem that the idea aims to solve]

As mentioned above, when the engine exhaust gas flows through the body passage, the outer wall of the body The paint may peel off due to the high surface temperature.

0004 Therefore, this invention is an off-road dump truck that can solve the above-mentioned problems. The purpose is to provide the body of

[Means to solve the problem]

A duct is installed on the front wall, and a partition plate is installed on this duct to connect the exhaust gas inlet and outside air. The exhaust gas introduction part is opened to the exhaust gas intake part and the front passage, and the exhaust gas introduction part is opened to the exhaust gas intake part and the front passage. The air introduction section has upper and lower holes that open to the outside air.

[Effect]

The outside air flowing through the outside air intake section cools the side walls, causing the paint on the outside walls to peel off due to heat. can be prevented.

[0005]

【Example】

As shown in Fig. 1, the body 1 is box-shaped with a front wall 2, a bottom wall 3, and left and right side walls 4, 4. , U-shaped front ribs 5 are attached to the top and bottom of the front wall 2 to form a front passage 6, U-shaped side ribs 7 are attached to the top and bottom of the left and right side walls 4 to form side passages 8. The front passage 6 and the side passage 8 are in continuous communication with the front rib 5 and the side rib 7, and the upper and lower front portions are connected to each other. A duct 9 is attached between the ribs 5, 5, and an exhaust gas introduction case 10 is attached to this duct 9. When the body 1 is placed in a reclining position relative to the vehicle body, the engine exhaust vent (not shown) The engine exhaust gas is transferred from the exhaust gas intake casing 10 to the duct 9 and the upper and lower front passages 6. , 6 and is discharged to the outside through the side passage 8. As shown in FIGS. 2 and 3, the duct 9 includes a lower surface 5a of the upper and lower front ribs 5, 5, It is attached across the top surface 5b, the front wall 2, and the side wall 4, and the partition plate 11 is attached inside it. The exhaust gas introduction part 12 and the outside air introduction part 13 are divided into two parts. 2 opens into the front passage 6 through upper and lower openings 14 and 15, and exhaust gas is taken in through the front opening 16. The outside air introduction part 13 opens to the outside through the upper and lower holes 17 and 18 to introduce outside air. By circulating outside air through the section 13 and cooling the side wall 4, the temperature rise of the side wall 4 is reduced and the coating is improved. Prevents the coating from peeling off.

[0006]

[Effect of the idea]

The side wall 4 can be cooled by the outside air flowing through the outside air introduction part 13 to reduce the temperature rise. This prevents the paint on the exterior walls from peeling off due to heat.

Claims (1)

[Scope of utility model registration request] Claim 1: A front passage 6 and a side passage 8 are formed by attaching a front rib 5 and a side rib 7 to a front wall 2 and a side wall 4, and a duct 9 is attached to the front wall 2. A partition plate 11 is attached to the duct 9 to form an exhaust gas introduction part 12 that opens into the front passage 6 and an outside air introduction part 13 on the side wall 4 side, and the exhaust gas introduction part 12 is connected to the front passage 6 and the exhaust gas intake. This body of an off-road dump truck is characterized in that it opens in a casing 10, and an outside air introduction part 13 is opened to the outside air through upper and lower holes 17 and 18.
