Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the structure of a canopy mounted on a small construction machine.

[Conventional technology]

A small construction machine is equipped with a canopy to ensure the operator's operating environment. As this canopy, one in which a canopy is attached to a pillar attached to a vehicle body frame is known.

[Problems to be solved by the device]

As described above, since the canopy only has the canopy, rain wind is blown from the left and right sides and the rear side to wet the operator's back and the operating environment cannot be sufficiently improved.

[Purpose of device]

The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the problem that rain wind is blown from one side and one side of the canopy to wet the operator's back. To provide a canopy.

[Means for Solving the Problems]

The first strut 6 is attached to one side of the vehicle body frame 1 near the front of the driver's seat 5, and the second and third struts 7 and 8 are attached to both sides of the body seat 1 near the rear of the driver's seat 5. A canopy 16 is attached over the upper ends of the first, second and third columns 6, 7, 8 and a side guard 9 is attached over the first column 6 and the third column 8, and the second column 7 is attached. And a canopy of a construction machine in which a windshield 10 is attached across the third support column 8.

[Action]

The windshield 10 on the rear side of the driver's seat 5 and the side guards 9 on the left and right sides of the driver's seat 5 can prevent rain and wind from blowing into the rear side of the driver's seat 5 and the left and right sides. , The third pillar 6,7,
Since three columns 8 are used, the mounting strength of the canopy 16 is strong, and there are no columns on the left, right, and other sides of the front side of the driver's seat 5, which facilitates the operator's entry and exit.

〔Example〕

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

In the drawings, reference numeral 1 denotes a body frame that serves as an upper revolving structure, and this body frame 1 has a canopy mounting portion composed of a horizontal portion 1a and a vertical portion 1b to which a floor 2 is attached, and a driver seat 5 is attached to the floor 2 The rear portion of the canopy 3 is supported by the left and right mounting devices 4 on the vertical portion 1b of the body frame 1 near the rear of the driver's seat 5.

The canopy 3 is located on the front left and right sides of the driver's seat 5, for example, on the right side of the first strut 6 and on the rear side of the driver's seat 5 on the left and right sides and on the other sides, for example, in the rear left and right sides It is provided with struts 7 and 8, and a left and right one-sided guard, for example, a right guard 9 is attached between the first stanchion 6 and the second stanchion 8, and the second and third stanchions 7 on the rear left and right sides are attached. A windbreak plate 10 is attached between the eight.

That is, as shown in FIG. 6, a mounting bracket 11 projecting rearward is fixedly provided on the second support column 7 on the left side of the rear portion.
A mounting bracket 12 projecting toward the second strut 7 (inward to the left) is fixedly attached to the third strut 8 on the rear right side. Further, the wind stop plate 10 has a substantially U shape in plan view.
On the left side (second pillar 7 side) of the mounting part that protrudes in the forward direction
13 is formed on the right side of the windshield 10 (on the side of the third support column 8)
A mounting portion 14 is formed at the right side so as to project to the right.

Then, the mounting portion 13 is attached to the mounting bracket 11 and the mounting portion 14
Are attached to the mounting bracket 12 by a plurality of elastic supporting mechanisms 15, and the wind stop plate 10 is attached to the second and third columns 7 and 8. As shown in FIG. 4, the elastic support mechanism 15 includes the mounting portion 1
A rubber tubular seat body 35 is fitted in the mounting holes 34 formed in 3, 14 and a hole 36 is formed in the mounting brackets 11, 12, and the plate 38 is brought into contact with the seat body 35 to form the plate 38 and the seat. The bolt 39, which penetrates the body 35, is screwed into the nut 37.

Further, the first, second and third support columns 6, 7, 8 hold a canopy 16. The lower ends of the second and third columns 7 and 8 on the left and right of the rear part are fixed to the connecting plate 27.

As shown in FIG. 5, the mounting device 4 includes the vertical portion 1b.
The support bracket 17 is fixedly mounted on the support bracket 17, and a hole 19 is formed in the horizontal portion 18 of the support bracket 17. The elastic mount member 20 is provided with bolts 22 and 23 provided on the upper and lower sides of an elastic body 21, and this elastic mount member 20 inserts a lower bolt 23 into the hole 19 and screw a nut 24 into the bolt 23 to connect the bolt 24 and the bolt 24. It is attached to the support bracket 17. Elastic mount member 20
A screw member 25 is provided on the upper surface of the bolt 22 in a state where the upper bolt 22 penetrates the lock member 26.The lock nut 26 is screwed onto the bolt 22, and the lock nut 26 presses the screw member 25. The screw member 25 is screwed onto a nut member 28 fixed to the connecting plate 27.

The lower end of the first strut 6 on the front right side of the canopy 3 and the lower end of the right guard 9 are attached to the floor 2 with bolts 30, and the lower end of the side plate member 31 is attached to the floor 2 with bolts 32. The upper end of the side plate member 31 is attached to the left side of the connecting plate 27 with a bolt 33.

The wind stop plate 10 is made of transparent or colored transparent acrylic.

Next, the operation will be described.

Since the wind stop plate 10 is provided on the back of the operator, wind and rain do not directly hit the operator.

In addition, the adjustment of the mount of the canopy 3 is performed by loosening the lock nut 26 in the mount device 4 to remove the screw member 25.
This is done by rotating and rotating the nut member 28, which is screwed into the screw member 25, up and down.

[Effect of device]

Since the back side of the driver's seat 5 is covered with the windshield 10 and the left and right sides of the driver's seat 5 are covered with the side guards 9, rain wind can be blown from the back side of the driver's seat 5, the left and right sides. Moreover, since the operator is not shaken, the operating environment of the operator can be improved.

Moreover, since the three columns of the first, second, and third columns 6, 7, and 8 are used, the mounting strength of the canopy 16 can be made strong, and the front side of the driver's seat 5 can be moved to the left, right, and other sides. Has no support posts, which makes it easier for operators to get on and off.
