The first end 721 of the pull rod 72 is provided with a hook 77 connected with the steel wire rope. The transmission member 73 is connected at one end with the first end 721. The elastic reset member 74 is connected at one end with the second end 722 and at the other end with the trolley 2. The locking block 75 is rotationally arranged on the trolley 2 and is connected at the other end of the transmission member 73. The locking block 75 is adapted to switch between a locking state and an unlocking state. In the unlocking state, the steel wire rope pulls the first end 721 of the pull rod 72 to rotate relative to the fixing seat 71 in a first direction, so as to drive the transmission member 73 to rotate the locking block 75 away from the guide ladder 1. In the locking state, the elastic reset member 74 pulls the second end 722 to rotate, so as to drive the first end 721 to rotate in a second direction and drive the transmission member 73 to rotate the locking block 75 towards the guide ladder 1 and abut against the guide ladder 1. The first direction is the clockwise direction in Figure 8 , and the second direction is the counterclockwise direction in Figure 8 .

[0096] According to one embodiment of the present application, as shown in Figure 1 , Figure 4 , Figure 8 and Figure 9 , the transmission member 73 comprises a transmission rod 731, a connecting rod 732 and a rotating shaft 733. One end of the transmission rod 731 is rotationally connected with the first end 721. The connecting rod 732 is connected with the other end of the transmission rod 731. One end of the connecting rod 732 is connected with the locking block 75. When the first end 721 rotates, the connecting rod 732 is adapted to be pushed to move by the transmission rod 731, so as to drive the locking block 75 to rotate towards or away from the guide ladder 1.

[0097] It can be understood that the locking block 75 is rotatably arranged on the trolley 2 through the rotating shaft 733, and the locking block 75 rotates around the center of the rotating shaft 733 under the driving of the connecting rod 732, when the hook 77 is pulled by the steel wire rope, the first end 721 of the pull rod 72 is driven to rotate clockwise, the pull rod 72 transmits the movement to the transmission rod 731 connected with the pull rod 72, and the transmission rod 731 transmits the movement to the connecting rod 732 through the universal joint bearing 734, at this time, the connecting rod 732 drives the locking block 75 to rotate away from the guide ladder 1, at this time, the locking block 75 does not contact the guide ladder 1, and the trolley 2 can smoothly slide along the guide ladder 1; when the steel wire rope is broken or the hook 77 is dropped, etc. When an accident occurs, the elastic reset member 74 pulls the second end 722 of the pull rod 72 to rotate counterclockwise, the first end 721 of the pull rod 72 also rotates counterclockwise, and finally the locking block 75 is driven by the transmission rod 731 and the connecting rod 732 to rotate towards the guide ladder 1, so that the locking block 75 abuts against the surface of the guide ladder 1, and as the rotation amount of the locking block 75 increases, the locking block 75 is more and more tightly fitted with the surface of the guide ladder 1, so that the friction between the locking block 75 and the guide ladder 1 is larger and larger, when the friction reaches a certain degree, the trolley 2 will stop moving and be locked on the guide ladder 1, avoiding the trolley 2 and the hopper 3 from falling, and ensuring the use safety of the material conveying machine.

[0098] It can be understood that the locking block 75 is formed with a sawtooth structure, and the sawtooth structure can abut against the guide ladder 1, further increasing the friction between the locking block 75 and the guide ladder 1, and the trolley 2 is more easily locked on the guide ladder 1.

[0099] According to one embodiment of the present application, as shown in Figure 4 and Figure 8 , the trolley 2 is provided with a mounting beam 76, and the fixing seat 71 is fixed to the mounting beam 76, when the trolley 2 slides, the steel wire rope pulls the hook 77 to pull the first end 721, and the second end 722 abuts against the mounting beam 76, at this time, the pull rod 72 rotates to the limit position, and the mounting beam 76 can limit the rotation of the pull rod 72, and at the same time, the mounting beam 76 can improve the connection strength of the steel wire rope and the trolley 2, and improve the safety and reliability when the steel wire rope pulls the trolley 2.

[0100] According to one embodiment of the present application, as shown in Figure 1 , Figure 4 and Figure 5As shown, the trolley 2 is provided with a guide assembly 24, the trolley 2 is slidably connected with the guide ladder 1 through the guide assembly 24, the sliding friction is reduced, and the trolley 2 is facilitated to slide on the guide ladder 1. Further, the guide assembly 24 comprises a mounting frame 241, a pressing wheel 242, a side wheel 243, and a hook wheel 244: the mounting frame 241 is mounted on the trolley 2; the pressing wheel 242 is rotatably arranged on the mounting frame 241 and is adapted to roll along the upper surface of the guide ladder 1; the side wheel 243 is rotatably arranged on the mounting frame 241 and is adapted to roll along the outer side surface of the guide ladder 1; and the hook wheel 244 is rotatably arranged on the mounting frame 241 and is located at the inner side of the guide ladder 1 and is adapted to roll along the inner side surface of the guide ladder 1. In the embodiment, the pressing wheel 242, the side wheel 243, and the hook wheel 244 roll along different surfaces of the guide ladder 1 and respectively play the roles of pressure bearing, side guiding, and preventing the trolley 2 from falling out of the guide ladder 1.

[0101] The embodiment of the present application provides a material conveying machine, which comprises a guide ladder 1, a trolley 2, and a hopper 3. The trolley 2 is slidably arranged on the guide ladder 1, and the trolley 2 is adapted to be connected with a driving device 5 to drive the trolley 2 to slide along the guide ladder 1. The hopper 3 comprises a front end 31 and a rear end 32, and the rear end 32 is rotatably connected with the trolley 2. The hopper 3 is adapted to be pushed by the trolley 2 to slide along the guide ladder 1. After the trolley 2 pushes the front end 31 to slide out of the guide ladder 1, the trolley 2 is adapted to continue to slide to push the hopper 3 to rotate relative to the guide ladder 1. The rear end 32 of the hopper 3 is rotatably connected with the trolley 2. After the front end 31 gradually slides out of the guide ladder 1, the rear end 32 of the hopper 3 rotates relative to the trolley 2, so that the hopper 3 is inclined. The material in the hopper 3 is gradually poured out by means of the inclined hopper 3, the automatic unloading of the material in the hopper 3 is realized, the working strength is reduced, and the application range of the material conveying machine is improved.
