A transparent resin plate 14 formed to follow the shape of the pillar 6 is stretched over the upper half and horizontal portion of the pillar 6 above the upper edge of the pillar 6, so that the driver can see through the side surface of the driver's seat 2 and the space above.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to the cabin canopy of a mini excavator that expands the driver's field of vision. It is something to do.

0002

[Conventional technology]

Conventionally, mini excavators have been designed to withstand light wind and rain and operate with a bucket or bucket. In order to ensure the safety of the driver against debris and stones flying from the jet arm, as shown in Figure 3, Between the driver's seat 2 and the bucket arm 3, which are provided on the swing frame 1 so as to Pillars 4 of a predetermined height stand upright parallel to each other at a predetermined interval in the front and back direction of the driver's seat 2. , 4 are provided, and extend parallel to each other from the top of each of the pillars 4, 4 above the driver's seat 2. In addition, its protruding tip should be placed around the front and rear of the driver's seat 2 with approximately the same curvature as the outer periphery of the rotating frame 1. A roof frame 5 connected by a member 5a extending horizontally is provided, and a tip of the roof frame 5 is provided. In order to support the rotating frame 1 near the rear of the driver's seat 2 along the outer circumference of the rotating frame 1, A support 5b is provided on the upper surface and connected to the member 5a, and a transparent resin plate is fitted in the upper half. A protective wall 8 having a window 7 is attached to the side surface of the support columns 4, 4 on the side of the bucket arm 3. , a roof 10 having a skylight 9 fitted with a transparent resin plate at the upper position in front of the driver's seat 2. It is attached to the upper surface of the roof frame 5.

0003

[Problem that the idea aims to solve]

However, the cabin canopy of the mini excavator described above does not allow for The driver's view is blocked by the roof 10 excluding the upper edge of the window 7 and the skylight 9 provided in the protection room 7. Obstacles such as electric wires and beams that are directly above the roof 10 and difficult to see from the driver's seat 2 because they are obstructed It is said that the bucket or bucket arm of the mini excavator may come into contact with objects. There was a problem.

0004 In view of the above-mentioned circumstances, the present invention is designed to cover the roof with a transparent plate like an extension of a window with a protective wall. The cabin of the mini excavator expands the driver's field of vision by forming This was done for the purpose of providing nopi.

[0005]

[Means to solve the problem]

This invention is installed on the side of the bucket arm side of the driver's seat, and The column, which has an inverted L shape when viewed from above, is erected so that the horizontal part of the column extends above the driver's seat. It is formed into an inverted L shape to cover the bucket arm side side surface and horizontal part of the support. The structure is such that a transparent plate material is attached to the support column.

[0006]

[Effect]

Therefore, in this invention, from the side of the bucket arm side of the driver's seat to the upper part of the driver's seat. Extensive visibility through the protective walls and roof, which are made transparent using transparent panels. ensure that

[0007]

【Example】

Embodiments of the present invention will be described below with reference to the drawings.

[0008] Figure 1 is a front view schematically showing the cabin and canopy of the mini excavator of the present invention. FIG. 2 is a view taken along arrow II-II in FIG. In the figure, the same parts as in Figure 3 are given the same symbols. There is.

[0009] Place a predetermined distance on the side of the bucket arm 3 of the driver's seat 2 in the front and back direction of the driver's seat 2. It has two inverted L-shaped supports 6, 6, and a bucket in the lower half of the height direction of the supports 6, 6. A thin steel plate 11 is attached to the side surface of the arm 3, and a piece plate 12 has bolt holes. is the outer surface of the part in the height direction of the columns 6, 6 located above the part where the thin steel plate 11 is stretched. and arranged and fixed at a predetermined interval on the upper surface of the horizontal part.

0010 Further, the lower end portion slightly overlaps the outer side of the upper edge of the thin steel plate 11, and the opposing support 6, has a width and an outer circumference commensurate with the interval between the height direction parts and the interval between the horizontal parts. The entire outer periphery is covered with trim rubber 13 to protect the edges, and the above-mentioned A transparent resin plate 14 formed in an inverted L shape so as to fit along the pillars 6, 6 is used, and the transparent resin plate 14 is Along the outer periphery of the fat plate 14, at a pitch that matches the arrangement interval of the piece plates 12. Bolt holes 15 are provided, and rubber washers are installed to protect the transparent resin plate 14 as shown in FIG. Piece-split the transparent resin plate 14 using the carrier 16, screw with washer 17, and cap nut 18. It is attached to the struts 6, 6 via the rate 12.

[0011] Thus, the vertical portions of the thin steel plates 11 and transparent resin plates 14 attached to the sides of the columns 6, 6 A protective wall 19 is formed by the transparent resin plate 14, and a roof 20 is formed by the horizontal part of the transparent resin plate 14. do.

0012 The upper half of the protective wall 19 provided between the driver's seat 2 and the bucket arm 3 and the top of the driver's seat 2 Since the roof 20 provided on the driver's seat 2 is formed from the transparent resin plate 14, A driver operating a mini excavator can withstand light wind and rain and has a working backhoe. You can ensure your body's safety from the dirt and stones scattered from the bucket and bucket arm 3, Moreover, the space above the driver's seat 2 cannot be seen through the upper half of the protective wall 19 and the protective roof 20. You can get an expanded field of view.

[0013] According to the above-mentioned configuration, the transparent material allows the upper edge of the window and the roof that obstruct the driver's view to be seen through. Made of resin plate, which expands the driver's field of view and improves work safety. be able to.

[0014] Note that the present invention is not limited to the above-mentioned embodiments; for example, the present invention is not limited to the above embodiments. After forming the part and the roof part using separate transparent resin plates, the two parts are joined together. The inverted L-shaped support can be made into a single inverted L-shaped support using a transparent plate material. may be supported, and other matters within the scope of the gist of this invention. Of course, various changes can be made.

[0015]

[Effect of the idea]

According to the cabin canopy of the mini excavator of this invention, the driver's seat and bucket A protective wall made of a transparent plate material is provided between the arm and the protective wall is connected to the protective wall. Since the roof is made of transparent plate material, the space to the side and above the driver's seat can be seen through, making it easier to drive. The operator's field of vision has been expanded, improving work safety and efficiency. It can be effective.
