[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In one embodiment, see Figure 1-Figure 13 , a crawler conveying device, comprising a support base 1, a walking mechanism 2 and a conveying mechanism 3; The walking mechanism 2 is arranged below the support seat 1, and includes a support plate 4 fixedly connected to the two side edges of the support seat 1. In order to improve stability, the support plate 4 is arranged to be a downwardly protruding triangular structure. The support plate 4 is vertically arranged in the middle of the front and rear sides of the lower surface of the support seat 1. The lower end of the support plate 4 is rotatably connected to the middle of the front-to-back main shaft 5. The main shaft 5 is fixedly connected to the middle of the upper surface of the support beam 6. A C-shaped connecting seat is arranged in the middle of the upper surface of the support beam 6. The front and rear ends of the main shaft 5 are fixedly connected through the C-shaped connecting seat, so that the middle part of the support beam 6 rotates along the center of the main shaft 5. The left and right ends of the support beam 6 are rotatably connected to the middle part of the deflection beam 7, and the two ends of the deflection beam 7 are rotatably connected to the walking pulleys 8, and the walking pulleys 8 are tightly pressed against the inside of the walking belt 9. Therefore, a walking belt 9 is arranged on both the front and rear sides below the support seat 1, and four walking pulleys 8 are arranged inside a walking belt 9. In order to ensure the passability of the conveying equipment, it is necessary to keep the two outermost walking pulleys 8 at a high position. At this time, the two sides of the oblique edges of the walking belt 9 are in an upward state, so that the approach angle and departure angle of the conveying equipment during the movement process are increased, and it can walk freely on uneven roads; The conveying mechanism 3 is arranged above the support seat 1, and a vertically arranged lifting slide bar 37 is slidably connected to the front and rear sides of the support seat 1. The upper end of the lifting slide bar 37 is fixedly connected to the front and rear ends of the lifting top plate 38 arranged in the front and rear directions. A rotating seat is arranged on the lower surface of the lifting top plate 38, and the rotating seat is rotatably connected to the middle part of the upper surface of the deflection support plate 39. The outer sleeve of the deflection support plate 39 is provided with a conveyor belt 43, and the function of conveying materials is realized by the rotation of the conveyor belt 43. In addition, a clearance groove 41 is arranged on the left and right ends of the deflection support plate 39, and the inner center position of the clearance groove 41 is rotatably connected to the deflection cylinder 40, and the piston rod of the deflection cylinder 40 extends in the direction away from the center of the deflection support plate 39. The end of the piston rod of the deflection cylinder 40 is rotatably connected to the left and right sides of the lower surface of the deflection support plate 39, and the deflection support plate 39 is limited by the lifting slide bar 37. The center of the plate 39 can only move vertically up and down, while the piston rods of the deflection cylinders 40 on both sides can extend and retract, which can control the up and down movement of the deflection support plate 39 on the one hand, and drive the deflection support plate 39 to pitch and deflect on the other hand. Moreover, since notches are provided on the left and right sides of the support seat 1, the support seat 1 is in an I-shaped structure, so that the deflection support plate 39 can pass through the notches, so that the deflection support plate 39 extends to the bottom of the support seat 1, so that the height of the feed end and the discharge end of the deflection support plate 39 at both ends can be freely adjusted, and when the piston rods of the two deflection cylinders 40 are retracted, the lower surface of the deflection support plate 39 will fall on the upper surface of the support seat 1, and the deflection support plate 39 is now attached to the support seat 1. At this time, the deflection support plate 39 is stably in a horizontal state and will not shake, and the entire equipment can be moved freely.

[0028] In one case of the present embodiment, the travel drive assembly 30 includes a drive shaft 49, and the drive shaft 49 is arranged to face forward and backward. The front and rear ends of the drive shaft 49 are rotatably connected to one end of the main shaft 5 close to the center of the support seat 1. The axis of the drive shaft 49 and the main shaft 5 are arranged in a colinear manner. A third pulley 25 is arranged on the front and rear sides of the drive shaft 49, and a fourth pulley 22 is arranged on one end of the first rotating shaft 12 on the left and right sides close to the center of the support seat 1. The fourth pulley 22 presses against the two ends of the second belt 23, and the third pulley 25 presses against the middle part of the second belt 23. Therefore, the third pulley 25 drives the fourth pulleys 22 on both sides through the second belt 23. The drive shaft 49 rotates synchronously, so when the drive shaft 49 rotates, a total of eight walking pulleys 8 are synchronously rotated through belt transmission, so that the two walking belts 9 in the front and rear rotate synchronously, and the middle part of the support beam 6 on the rear side is fixedly connected to the extension beam 15 arranged in the front and rear directions, and the front end of the upper surface of the extension beam 15 is provided with a first driving motor 26, and the output shaft of the first driving motor 26 is fixedly connected to the first pulley 27, and the first pulley 27 is connected to the second pulley 29 through the first belt 28, and the second pulley 29 is fixedly connected to the middle part of the driving shaft 49, so the first driving motor 26 can drive the driving shaft 49 to rotate through the belt transmission. And for stability, a fixed horizontal plate 24 is set on the side of the support beam 6 close to the center of the support seat 1, and the two ends of the fixed horizontal plate 24 are rotatably connected to the first rotating shaft 12, and the middle part of the fixed horizontal plate 24 is fixedly connected to the main shaft 5, so that the driving shaft 49 can stably drive the first rotating shaft 12 to rotate.

[0029] In one case of this embodiment, the first buffer components 21 driving the support beam 6 to rotate in a parallel state with the support seat 1 are arranged on both sides of the support beam 6, so when the support beam 6 deflects left and right relative to the support seat 1, the first buffer component 21 will drive the support beam 6 to rotate to a parallel state again, and the end of the support beam 6 is provided with a second buffer component 36 driving the end of the deflection beam 7 away from the center of the support seat 1 to rotate away from the ground. The first buffer component 21 and the second buffer component 36 achieve a buffering effect during the walking process of the entire device, which is equivalent to the shock absorber of the vehicle.

[0030] In one case of the present embodiment, the first buffer component 21 includes a buffer frame 16 fixedly connected to the support beam 6, the buffer frame 16 is a U-shaped structure with an opening upward, the buffer frame 16 is arranged on the left and right sides of the upper surface of the support beam 6, the upper end of the buffer frame 16 is fixedly connected to the first buffer slide bar 17 arranged in the left and right directions, the middle part of the first buffer slide bar 17 is slidably connected to the buffer slider 18, the upper surface of the buffer slider 18 is rotationally connected to the lower end of the first buffer support rod 19, the upper end of the first buffer support rod 19 is rotationally connected to the lower surface of the support seat 1, and the upper end of the first buffer support rod 19 is inclined in the direction away from the center of the support seat 1, and a first buffer spring 20 is arranged between the buffer slider 18 and the buffer frame 16, and the first buffer spring 20 is sleeved on the side of the first buffer slide bar 17 close to the center of the support beam 6, so that the first buffer spring 20 will push the buffer slider 18 to move in the direction away from the center of the support beam 6.

[0031] In one case of the present embodiment, the second buffer assembly 36 includes a buffer block 31 arranged on one side of the support beam 6 close to the center of the support seat 1, the buffer block 31 is fixed on the left and right sides of the support beam 6, the middle part of the buffer block 31 is slidably connected with a second buffer slide bar 33 arranged in a left and right direction, the upper end of the deflection block 35 is fixedly connected to the lower surface of the rotating sleeve 14, the lower end of the deflection block 35 is rotatably connected to the upper end of the second buffer support rod 34, the lower end of the second buffer support rod 34 is rotatably connected to the end of the second buffer slide bar 33 away from the center of the support beam 6, and a second buffer spring 32 is sleeved on the side of the second buffer slide bar 33 away from the center of the support beam 6, so when the rotating sleeve 14 rotates synchronously with the deflection beam 7, the second buffer spring 32 will be stretched or compressed.

[0032] In one case of the present embodiment, the lower end of the lifting slide bar 37 is fixedly connected to the fixed block 46, the middle part of the fixed block 46 is rotatably connected to the driving roller 47 arranged in the front-back direction, the driving roller 47 is pressed tightly against the lower middle part of the conveyor belt 43, and a second driving motor 48 is arranged on the fixed block 46 on the rear side, the output shaft of the second driving motor 48 is fixedly connected to the rear end of the driving roller 47, the second driving motor 48 drives the conveyor belt 43 to rotate through the driving roller 47, and the two ends of the deflection support plate 39 are provided with a clearance groove 41, and the two ends of the clearance groove 41 are rotatably connected to the conveyor roller 42 arranged in the front-back direction, and the conveyor roller 42 is pressed tightly against On both sides of the conveyor belt 43, the conveyor rollers 42 will press the conveyor belt 43 tightly, the driving rollers 47 will drive the conveyor belt 43 to rotate, and the conveyor belt 43 will pass through the give way groove 41, so the conveyor belt 43 will not interfere with the end of the deflection support plate 39, and a plurality of support frames 44 are evenly distributed on the upper surface of the deflection support plate 39. The upper ends of the support frames 44 are rotatably connected to the support rollers 45 arranged in the front and rear directions, and the support rollers 45 will press the lower surface above the conveyor belt 43. Therefore, even if the spacing between the drive rollers on the left and right sides is large, the support rollers 45 will lift the middle part of the conveyor belt 43, thereby ensuring the stable conveying effect of the conveyor belt 43.

[0033] During the implementation of this embodiment, the deflection cylinder 40 is first started, and the piston rods of the two deflection cylinders 40 are retracted, and the deflection support plate 39 falls on the upper surface of the support seat 1. The angle of the deflection support plate 39 is fixed and will not shake.

[0034] Walking action, start the first drive motor 26, the first drive motor 26 rotates the drive roller 47 through the belt transmission, the drive roller 47 drives the first rotating shaft 12 to rotate through the belt transmission, the first rotating shaft 12 drives the walking pulley 8 to rotate through the gear transmission, so that the front and rear two walking belts 9 rotate, and then the whole device starts to walk. For example, when the device moves to the right, a step appears on the right side and needs to be moved upward. At this time, the walking belt 9 on the right side will contact the edge of the step. At this time, the deflection beam 7 on the right side will rotate clockwise, so that the walking belt 9 between the two walking pulleys 8 on the right side is pressed tightly against the surface of the step. At this time, the support beam 6 will rotate counterclockwise, so that the walking belt 9 between the walking pulleys 8 on the left side is always in contact with the ground, thereby ensuring the driving force, and because the front and rear support beams 6 can rotate relative to each other, when the contact heights of the front and rear walking belts 9 are different, the upper support seat 1 can also maintain a certain horizontal state. The entire equipment reduces the shaking of the support seat 1 through the rotation of the support beam 6 and the deflection beam 7, thereby reducing the shaking of the deflection support plate 39 above, making it easier for the entire equipment to walk on uneven ground, and can achieve a climbing effect, adapting to the movement of open-pit mines.

[0035] Conveying action, when the equipment moves to the target position, stop the first drive motor 26, lock the walking pulley 8 at this time, start the deflection cylinder 40, and the piston rods of the deflection cylinders 40 on both sides will extend, so that the lifting top plate 38 will drive the deflection support plate 39 to rise, and adjust the extension length of the piston rods of the deflection cylinders 40 on both sides according to the required moving direction, so that the deflection support plate 39 is tilted. For example, if the material at the lower position on the left side needs to be transported to the higher position on the right side, the deflection support plate 39 is rotated counterclockwise at this time so that the deflection support plate 39 faces the upper right side, and the excavation equipment is moved to the left end of the equipment, and the second drive motor 48 is started. The second drive motor 48 drives the conveyor belt 43 to rotate clockwise through the drive roller 47. The excavation equipment places the mineral material on the left end of the conveyor belt 43, and the mineral material moves to the upper right side with the conveyor belt 43, thereby achieving the effect of mineral material transportation.

[0036] The present invention is applicable to a crawler conveying equipment, by arranging left-right deflected support beams 6 on the front and rear sides below the support seat 1, and the left and right ends of the support beam 6 are rotatably connected to the deflection beam 7, so that the walking belts 9 arranged on the front and rear sides of the support seat 1 can always be close to the ground, which is convenient for the whole equipment to move on the ground at different heights in the open-pit mine. In addition, since the walking mechanism 2 is the walking belts 9 arranged on the front and rear sides, it will not interfere with the rotation of the deflection support plate 39, so that the conveyor belt 43 can transport and process materials at a lower height, making the use of the equipment more convenient.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
