[0022] This utility model provides a foldable protective device for an excavator, including a bracket 12 mounted on the excavator. A folding assembly is provided on the upper part of the bracket 12, and a roof assembly is connected to the folding assembly. The roof assembly can rotate around the folding assembly as a pivot, lowering the overall height of the excavator. The folding assembly includes a folding seat 7 fixedly mounted on the top of the bracket 12, with pin holes 6 and rotating holes 8 at its upper and lower ends, respectively. The roof assembly includes a folding plate 5, with two through holes corresponding to the pin holes 6 and rotating holes 8 at its lower end. It also includes a pin shaft and a rotating shaft, with the pin shaft detachably passing through the pin holes 6. The rotating shaft passes through the rotating hole 8 and the lower through hole in sequence, with the upper through hole and the lower through hole. The rear side of the folding plate 5 is fixedly connected to the upright 3, which is coaxial with the bracket 12 when it is in the vertical position. The top rod of the upright 3 is also equipped with a canopy 1. The front side of the upright 3 is equipped with a handle 4. The bracket 12 is also equipped with a positioning seat 9 near the lower part of the folding seat 7. The positioning seat 9 has an inclined surface for supporting the folding plate 5 at its upper and lower sides. The bracket 12 also includes a protective net, which includes side plates 11 on both sides and a grid 10 in the middle. The upper and lower ends of the side plates 11 are provided with screw holes 2 and are detachably connected to the bracket 12 and the upright 3 by bolts.
[0023] The first embodiment of this utility model is as follows:
[0024] A foldable protective device for an excavator includes a bracket 12 mounted on the excavator. The lower end of the bracket 12 is provided with an ear plate 13, which is connected to the excavator. The lower end of the bracket 12 has a base plate, from which two iron rods extend upward. Correspondingly, two uprights 3 are also provided, which are coaxial with the two iron rods in the vertical state.
[0025] The protective netting includes side plates 11 on both sides and a grid 10 in the middle. The side plates 11 and the grid 10 are welded together. The grid 10 is made of crisscrossing iron bars, which can block branches when passing through trees and bushes. The upper and lower ends of the side plates 11 are provided with screw holes 2, and are detachably connected to the bracket 12 and the upright 3 by bolts. A pin structure can also be used to ensure that the protective netting can be quickly disassembled. The protective netting can be removed when the canopy 1 needs to be folded, or in some cases, the protective netting is not required. At the same time, the protective netting is small in size and weight, and is easy to carry.
[0026] The folding assembly includes a folding seat 7 fixedly installed at the top of the bracket 12. The folding seat 7 is supported by two identical plates with a gap between them. The folding plate 5 can be installed inside the gap. A vertical rod 3 is fixedly connected to the rear side of the folding plate 5. The top rod of the vertical rod 3 is also equipped with a canopy 1. The upper and lower ends of the folding seat 7 are respectively provided with a pin hole 6 and a rotating hole 8. The lower end of the folding plate 5 is provided with two through holes corresponding to the pin hole 6 and the rotating hole 8. The pin passes through the pin hole 6 and the upper through hole in a detachable manner, and the rotating shaft passes through the rotating hole 8 and the lower through hole in a detachable manner. In the working state, the folding plate 5 is rotated to a vertical state and then positioned by the pin. At this time, the vertical rod 3 is coaxial with the bracket 12. When folding is required, the pin is pulled out, which allows the canopy 1 to rotate around the rotating shaft.
[0027] To ensure the stability of the pin during operation, a threaded screw is installed on the other end of the pin, which is then secured with bolts to prevent the pin from accidentally falling off due to vibration.
[0028] A handle 4 is installed on the front side of the upright 3 for easy handling when folding.
[0029] A positioning seat 9 is also installed on the bracket 12 near the folding seat 7. An inclined surface for supporting the folding plate 5 is provided on the upper side of the positioning seat 9. The positioning seat 9 is made of plate material and is located directly below the gap in the middle of the folding seat 7. After the upright 3 and the folding plate 5 are rotated, the folding plate 5 can be pressed against the inclined surface to complete the positioning and ensure its stability.
[0030] The inclination angle of the ramp is the same as the inclination angle of the upright 3 when it is rotated to this point. The increased contact surface makes it more stable on the one hand, and the folding plate 5 will not be damaged on the other hand. At the same time, the highest point of the canopy is lower than the highest point of the support, which greatly improves the passability.
[0031] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.
[0032] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
