Description

Technical Field

[0001] This utility model relates to the field of tunnel construction, specifically a tunnel drilling rock transport and unloading hopper. Background Technology

[0002] Tunnel construction aims to open up roads by breaking through mountains. During tunnel construction, a large amount of rock is generated, some of which is too large. These larger rocks need to be crushed and then transported out by truck. A search of application CN20201044790.8, which discloses a rock transport mechanism for tunnel drilling and blasting engineering, reveals a transport vehicle comprising a truck bed and wheels. The rear of the truck bed is equipped with a retractable inclined support rod, which is fitted with a helical telescopic drive mechanism. An electric motor is located below the truck bed, driving the wheels. The helical telescopic drive mechanism and the electric motor are equipped with a wireless receiver, which is also equipped with a remote control for operation. The described transport vehicle moves and is supported at an angle. The stone transport mechanism can stay close to the blasting surface, and a large portion of the stones that fall forward after the blast will fall onto the truck bed. Furthermore, through wireless control, the transport vehicle can exit the tunnel along the track, avoiding the need for workers to enter areas with large amounts of smoke and dust after the blast. It can also quickly and automatically load the blasted stones. However, the above description still has the following drawbacks in actual use: the transport device is not convenient for unloading the transferred stones during use, and in some cases, the driver needs to be on the vehicle to operate it, resulting in a lack of protective structure for the driver during transportation. Therefore, it is necessary to design a more practical tunnel drilling stone transport and unloading bucket truck. Utility Model Content

The tops of the two lifting rods 25 are hinged to the two sides of the bottom of the truck bed 13.

[0024] In practical use: two motors 21, in conjunction with bearings 23, drive two threaded rods 22 to rotate. The two threaded rods 22 drive two sliders 24 to move within two strip grooves 12. The two sliders 24 drive two lifting rods 25, which are hinged to them, to move. The two lifting rods 25 drive the bucket 13, which is hinged to them, to move. The bucket 13 drives two adjusting blocks 14 to rotate on the surfaces of two fixed shafts 16. With the help of two lubricating rings 19, the rotation efficiency is increased, thereby realizing the unloading of stones from the bucket 13.

[0025] Please see Figure 4 The protective component 3 includes two sets of fixing rods 31 installed on the top two sides of the front of the vehicle 1. The top of the two sets of fixing rods 31 is inserted and connected to the two ends of the bottom of the protective housing 32. The top surfaces of the two sets of fixing rods 31 are each fitted with a first spring 33. The bottom of the two sets of first springs 33 is fixedly connected with a limit block 34. The bottom of the inner wall of the protective housing 32 is provided with several second springs 35. The bottom of the several second springs 35 is provided with a top plate 36.

[0039] In use, two motors 21, in conjunction with bearings 23, drive two threaded rods 22 to rotate. The two threaded rods 22 drive two sliders 24 to move within two strip grooves 12. The two sliders 24 drive two lifting rods 25, which are hinged to them, to move. The two lifting rods 25 drive the truck bed 13, which is hinged to them, to move. The truck bed 13 drives two adjusting blocks 14 to rotate on the surfaces of two fixed shafts 16. With the help of two lubricating rings 19, the rotation efficiency is increased, thus unloading the stones in the truck bed 13. The protective shell 32 provides buffer support for stones falling into the tunnel. When the protective shell 32 is under force, the inner walls of the two sets of slots 37 are inserted and connected to the tops of the two sets of fixed rods 31. With the help of two sets of limiting blocks 34, the two sets of first springs 33 are compressed to different degrees. At the same time, the protective shell 32, in conjunction with the top plate 36, compresses several second springs 35 to different degrees, buffering the impact of external stones and protecting the top of the truck head 1 from injury to the driver.
