[0047] In the working state, the two hydraulic motors 83 respectively drive the two driving wheels 72 to rotate, so that the two rubber tracks 74 move on the ground. When the two driving wheels 72 rotate forward at the same speed, the crawler hauler moves forward in a straight line; when the two driving wheels 72 rotate backward at the same speed, the crawler hauler moves backward in a straight line; when the two driving wheels 72 stop rotating, the crawler hauler stays on the ground; when the two driving wheels 72 rotate at different speeds, the crawler hauler turns.

[0048] The bucket 3 is located above the chassis 1, and is connected to the top of the chassis 1 through a lifting drive mechanism, which raises or lowers the bucket 3 relative to the chassis 1. The lifting drive mechanism includes a scissor frame 31 and a third oil cylinder 32, and the scissor frame 31 includes an upper frame body 311, a lower frame body 312 and an X-shaped frame body 313. The upper frame body 311 and the lower frame body 312 are both square frame structures, and the lower frame body 312 is fixedly connected to the top of the chassis 1.

[0049] The upper frame 311 is located directly above the lower frame 312. The upper and lower sides of the front end of the X-shaped frame 313 are respectively hinged to the upper frame 311 and the lower frame 312. Two first sliders 314 are respectively slidably provided on the left and right sides of the rear of the upper frame 311, and two second sliders 315 are respectively slidably provided on the left and right sides of the rear of the lower frame 312. The upper side of the rear end of the X-shaped frame 313 is respectively rotatably connected to the two first sliders 314, and the lower side thereof is respectively rotatably connected to the two second sliders 315. One end of the third oil cylinder 32 is hinged to the bottom frame 1, and the other end is hinged to the rear of the X-shaped frame 313. The third oil cylinder 32 drives the upper frame 311 to move up and down through the X-shaped frame 313.

[0050] When the piston rod of the third oil cylinder 32 is in the working state, when the piston rod of the third oil cylinder 32 is extended, the two first sliding blocks 314 on the left and right sides of the rear part of the upper frame 311 slide forward relative to the upper frame 311, driving the upper frame 311 to maintain a horizontal state and rise, thereby driving the bucket 3 to rise; when the piston rod of the third oil cylinder 32 is contracted, the two first sliding blocks 314 on the left and right sides of the rear part of the upper frame 311 slide backward relative to the upper frame 311, driving the upper frame 311 to maintain a horizontal state and descend, thereby driving the bucket 3 to descend.

[0051] In addition, a flip frame 33 with an integral structure is fixed to the bottom of the truck bed 3, the front end of the flip frame 33 is hinged to the top of the lifting drive mechanism, and the middle part of the flip frame 33 is connected to the lifting drive mechanism through a first oil cylinder 34. The first oil cylinder 34 causes the truck bed 3 to flip upward and forward relative to the lifting drive mechanism.

[0052] Specifically, an upper hinge seat 316 is provided on the upper side of the front end of the upper frame body 311, and a lower hinge seat 317 is provided on the lower side of the front end thereof, and the front end of the flip frame 33 is rotatably connected to the upper hinge seat 316. The first oil cylinder 34 is located above the third oil cylinder 32, and its front end is rotatably connected to the lower hinge seat 317, and its rear end is rotatably connected to the middle part of the flip frame 33. The first oil cylinder 34 drives the flip frame 33 to rotate around the connection between it and the lower hinge seat 317. A shock-absorbing bracket 318 is fixed to the upper surface of the rear end of the upper frame body 311, and a plurality of shock-absorbing pads 319 are provided on the shock-absorbing bracket 318 to match the rear end bottom of the flip frame 33.

[0053] In the working state, when the piston rod of the first oil cylinder 34 is extended, the bucket 3 and the turning frame 33 rotate upward relative to the connection between the front end of the turning frame 33 and the upper hinge seat 316, and the material contained in the bucket 3 is poured out. After the material is poured out, the piston rod of the first oil cylinder 34 contracts, driving the bucket 3 and the turning frame 33 to reset.

[0054] The bucket 4 is located at the front side of the bucket 3 and is rotationally connected to the bucket 3 through two driving arms 41 arranged symmetrically on the left and right. A second cylinder 42 is arranged on the rear side of each driving arm 41. The second cylinder 42 is synchronously extended and retracted, and the bucket 4 is flipped upward and forward relative to the bucket 3 through the driving arms 41.

[0055] Specifically, the front side plate of the bucket 3 is arranged obliquely, and two mounting plates 43 are symmetrically fixed on the outer walls on the left and right sides of the bucket 3. The left and right outer side walls of the bucket 4 are respectively fixedly connected to one end of the two driving arms 41, and the upper rear end of the driving arm 41 is rotatably connected to the mounting plate 43. The rear end of the cylinder body of the second oil cylinder 42 is hinged to the mounting plate 43 on the same side, and the end of its piston rod is hinged to the lower rear end of the driving arm 41. When working, the second oil cylinder 42 drives the bucket 4 to rotate around the connection between the driving arm 41 and the mounting plate 43.

[0056] In the working state, the piston rods of the two second oil cylinders 42 are synchronously contracted, and the two driving arms 41 rotate forward around the connection between them and the mounting plate 43, and the bucket 4 falls to the front side of the crawler hauler. The crawler hauler moves forward to shovel the materials on the ground into the bucket 4. After that, the piston rods of the two second oil cylinders 42 are synchronously extended to drive the bucket 4 to move up and down and backward. The materials in the bucket 4 slide into the bucket 3 through the rear side of the bucket 4. The above actions are repeated to fill the bucket 3 with materials. After the crawler hauler reaches the destination, the third oil cylinder 32 drives the bucket 3 to rise to the set height through the X-shaped frame 313, and the first oil cylinder 34 drives the bucket 3 to flip forward to unload the materials in the bucket 3.

[0057] The control unit is arranged on the fixed plate 62 of the operating table 6, and includes a single manual valve, a double manual valve, a triple manual valve and a throttle handle 91.

The top of the operating platform 6 is provided with elongated holes 64, which are equal in number to the handles and correspond in position to each other, and each handle is located inside the corresponding elongated hole 64. Specifically, the throttle handle 91 is installed on the throttle rotating plate, and is used to control the output power of the engine 81, thereby realizing the control of the walking speed of the crawler transporter. The first handle 92 is located on the right side of the throttle handle 91, and is connected to the control end of the single manual valve. The first handle 92 is used to control the working state of the double gear pump 82, and realizes the distribution of oil supply and return to the hydraulic motor and each cylinder.

[0059] The second handle 93 and the third handle 94 independently control the working state of the hydraulic motor 83 located on the left and the right respectively. The second handle 93 and the third handle 94 are self-resetting control handles. Pushing the second handle 93 or the third handle 94 forward makes the rubber track 74 move forward, and pulling the second handle 93 or the third handle 94 backward makes the rubber track 74 move backward. After releasing, the second handle 93 or the third handle 94 is in the middle position, and the rubber track 74 does not move. The crawler transporter can move forward, backward, stop or turn by controlling the second handle 93 and the third handle 94 respectively. In addition, the fourth handle 95 controls the third oil cylinder 32 to raise or lower the bucket 3, the fifth handle 96 controls the first oil cylinder 34 to flip the bucket 3, and the sixth handle 97 controls the second oil cylinder 42 to drop or lift the bucket 4, and they cooperate with each other to realize material loading, transfer and unloading.
