Description

Technical Field

[0001] The present invention relates to the technical field of material conveying equipment, and particularly to an adjustable bulk material guiding and conveying equipment. Background Art

[0002] During the processing of agricultural products, conveyors are needed to transport the agricultural products. Although the existing equipment can complete the material transportation task to a certain extent, there are also some significant disadvantages. First, the traditional conveyor belt system is prone to cause material fragmentation and loss during the material falling process. Second, in the process of the material moving from one conveying point to another, the traditional system lacks an effective buffer device. Especially for high-drop transportation tasks, the material may be impacted, resulting in a decline in quality. In addition, during the material conveying process, the material is likely to slide outside the conveyor belt due to mechanical vibration.

[0003] A material conveyor for primary processing of agricultural products with the Chinese patent document publication number CN119329998A includes a shielding falling cover. An opening is provided at the bottom of the shielding falling cover. A conveying belt is arranged below the opening, and the distance between the upper surface of the conveying belt and the bottom opening of the shielding falling cover can be adjusted; conveying baffles are arranged on both sides of the conveying belt. Belt driving rollers are rotatably installed at both ends between the opposite surfaces of the two conveying baffles. Among them, the two belt driving rollers are synchronously driven and matched through the conveying belt. A belt support plate is also fixed between the two conveying baffles. The belt support plate is used to support the conveying belt. Among them, the belt support plate does not pass below the bottom opening of the shielding falling cover, and uses the elasticity of the conveying belt itself to buffer the falling of the material. And one end of the belt support plate close to the shielding falling cover is provided with a downwardly inclined bend; an auxiliary triangular hypotenuse is arranged on the upper surface of the conveying belt. However, this patent still has some deficiencies: when conveying materials of different shapes, the materials placed unstably will displace on the conveyor belt, causing collisions between the materials, resulting in wear of the materials during the conveying process.

The axle frame is fixed at both ends of the support frame, the main shaft is rotatably installed on the axle frame and passes through the center of the arc bend of the guiding track, the end of the guiding track is fixedly connected to the axle frame through a connecting block, the pulleys of the pulley group are coaxially fixed on the main shaft, a plurality of pushing blocks are further fixed on the belt of the pulley group, the pushing blocks are arranged in one-to-one correspondence with the sliding seats, and when the pulley group rotates, the pushing blocks can abut against the clamping rods and push the seat body to slide along the guiding track.

[0009] Preferably, the width of the conveying belt is the same as the length of the supporting rod.

[0010] Preferably, one end of the support frame is further provided with an engagement mechanism. The engagement mechanism includes an arc-shaped track frame, a sliding carriage, a locking rod, and an engagement plate. The arc-shaped track frame is fixed to one end of the support frame. The sliding carriage is slidably clamped on the arc-shaped track frame. The engagement plate is fixed to the sliding carriage. One side of the engagement plate engages with the output end of the conveyor belt and is used to receive materials. One end of the locking rod is fixed to the end of the sliding carriage, and the other end of the locking rod is slidably connected to the side surface of the shaft frame.

The material is always located within the depression during the conveying process, preventing the material from rolling along the surface of the conveyor belt. During conveying, multiple materials can form depressions at different positions on the conveyor belt, further preventing rolling collisions between materials. Description of the Drawings

Detailed implementation manners

[0017] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention.

[0018] As Figures 1 to 8 shown, the present invention provides an embodiment of an adjustable bulk material guiding and conveying device, including two parallel support frames 1. The bottom of the support frame 1 is fixedly connected through support legs 2. A material supporting mechanism 3 and a guiding track 4 are arranged inside the support frame 1. The guiding track 4 is a closed track with arc bends at both ends, similar to the shape of a runway. The two straight line positions of the guiding track 4 are arranged vertically and parallel to each other up and down, and the material supporting mechanism 3 can slide along the guiding track 4.

[0019] The blanking mechanism 3 includes a plurality of support components 5 slidably arranged along the outer circumference of the guiding track 4. The blanking mechanism 3 is integrally covered with a conveying belt 6 along the outer circumference. The top of each support component 5 abuts against the inner side of the conveying belt 6, and the outer surface of the conveying belt 6 is used for placing materials.

[0020] The support component 5 includes a sliding seat 7, an elastic telescopic rod 8, a rod frame 9 and a supporting rod 10. The sliding seat 7 is slidably connected to the guiding track 4. The elastic telescopic rod 8 is fixed on the upper surface of the sliding seat 7. The rod frame 9 is fixed at the top end of the elastic telescopic rod 8. The supporting rod 10 is horizontally fixed on the rod frame 9. The supporting rods 10 of the plurality of support components 5 are arranged in parallel to form a supporting surface. The width of the conveying belt 6 is the same as the length of the supporting rod 10 so that the supporting rod 10 can completely support the conveying belt 6, and the upper half of the conveying belt 6 is attached to the supporting surface.

[0021] The sliding seat 7 includes a seat body 11, a spring piece 12 and a clamping rod 13. The spring piece 12 is arranged in a V shape. The upper end of the spring piece 12 is fixed to the inner top of the seat body 11. The seat body 11 is slidably connected to the side of the guiding track 4. The lower end of the spring piece 12 is slidably connected to the outer circumference of the guiding track 4. The clamping rod 13 is fixed to the lower end of the seat body 11 and is slidably clamped with the inner circumference of the guiding track 4.

[0022] The blanking mechanism 3 further includes a power component 14. The power component 14 includes a shaft frame 15, a main shaft 16 and a pulley group 17. The shaft frame 15 is fixed at both ends of the support frame 1. The main shaft 16 is rotatably installed on the shaft frame 15 and passes through the center of the arc bending part of the guiding track 4. The end of the guiding track 4 is fixedly connected to the shaft frame 15 through a connecting block 18. The pulleys of the pulley group 17 are coaxially fixed on the main shaft 16. A plurality of pushing blocks 19 are also fixed on the belt of the pulley group 17. The pushing blocks 19 are arranged in one-to-one correspondence with the sliding seats 7. When the pulley group 17 rotates, the pushing blocks 19 can abut against the clamping rods 13 and push the seat body 11 to slide along the guiding track 4.

[0023] When conveying materials, first place the materials downward on the conveyor belt 6. At this time, the bottom of the materials contacts the conveyor belt 6. Under the action of gravity, the supporting rod 10 at the bottom of the conveyor belt 6 is pressed downward, while the supporting rod 10 on the outside of the materials does not contact the materials, so the original height is maintained. At this time, a depression is formed on the conveyor belt 6, and it is difficult for the supporting rod 10 to drop when the materials squeeze the supporting rod 10 from the side. Therefore, the materials can always be located in the depression. When moving the materials, the push block 19 is driven to move by the pulley group 17 of the power component 14, and the push block 19 pushes each slide 7 to slide along the guide rail 4 together. At this time, the supporting rod 10 at the bottom of the materials and the supporting rod 10 on the outside of the materials move at the same time to drive the materials to move. When moving, the supporting rod 10 can also drive the conveyor belt 6 forward by friction. The materials are always located in the depression during the conveying process to prevent the materials from rolling along the surface of the conveyor belt 6. During transportation, multiple materials can form depressions at different positions of the conveyor belt 6 to further prevent rolling collisions between the materials.

[0024] A connecting mechanism 20 is also provided at one end of the support frame 1, and the connecting mechanism 20 includes an arc track frame 21, a slide 22, a locking rod 23 and a connecting plate 24. The arc track frame 21 is fixed at one end of the support frame 1, the slide 22 is slidably connected to the arc track frame 21, and the connecting plate 24 is fixed on the slide 22. One side of the connecting plate 24 is connected to the output end of the conveyor belt 6 and is used to receive materials. One end of the locking rod 23 is fixed to the end of the slide 22, and the other end of the locking rod 23 is slidably connected to the side of the shaft frame 15. A locking knob 25 is threadedly connected to the locking rod 23. Tightening the locking knob 25 can make the bottom of the locking knob 25 abut against the side of the shaft frame 15.

[0025] A discharge plate 26 is slidably mounted at the bottom of the connecting plate 24, and the discharge plate 26 and the bottom of the connecting plate 24 are also connected by a reset spring 27. A plurality of rotating friction blocks 28 are fixed on the surface of the discharge plate 26, and a through hole is opened on the surface of the connecting plate 24, and the rotating friction blocks 28 pass through the connecting plate 24 from the through hole.

[0026] The cross section of the rotating friction block 28 is a horizontally arranged teardrop-shaped structure. A friction seat 29 is fixed to the surface of the unloading plate 26. The rear end of the rotating friction block 28 is rotatably mounted on the friction seat 29. The diameter of the rear end of the rotating friction block 28 is greater than the thickness of the connecting plate 24.

[0027] The working principle of the connection mechanism 20 is as follows: After the material falls from the conveyor belt 6, the connection plate 24 is used to receive and guide the material. After loosening the locking knob 25, the carriage 22 is moved up and down along the arc-shaped track frame 21 to adjust the height of the connection plate 24. After the adjustment is completed, the locking knob 25 is tightened, so that the material on the conveyor belt 6 can move to subsequent platforms at different heights, realizing the buffering of the material and preventing the material from directly falling from the higher conveyor belt 6 to other platforms. When the slide base 7 moves to the position of the connection plate 24, the clamping rod 13 on the slide base 7 can push the discharge plate 26 forward. The movement of the discharge plate 26 drives the rotating friction block 28 to move forward. The rear end of the rotating friction block 28 is higher than the surface of the connection plate 24, so it can contact the bottom of the material on the connection plate 24. When the rotating friction block 28 moves forward, the rotating friction block 28 will rotate and cause the front end to tilt up. After the front end of the rotating friction block 28 tilts up, it abuts against the bottom of the material to increase the friction with the material, and pushes the material to move along the surface of the connection plate 24. When the clamping rod 13 disengages from the discharge plate 26, the return spring 27 drives the discharge plate 26 to move backward. After the rotating friction block 28 moves backward, the front end disengages from the material, reducing the friction with the material and preventing the material from moving backward. Repeating the above steps can drive the material to move forward unidirectionally along the surface of the discharge plate 26, so that when the discharge plate 26 is adjusted to a horizontal state or a raised state, it can still convey the material it receives to platforms at different heights.
