Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a material leakage recovery device for a baling and wrapping machine. Background Technology

[0002] After crop harvesting, a large amount of crop straw is discarded or burned, which wastes resources, pollutes the environment, and to some extent affects the sustainable development of the economy and society. By crushing the straw, baling it, and wrapping it for micro-storage before feeding it to livestock, feed costs can be saved, and the straw can be returned to the field through livestock manure, promoting a virtuous cycle in agriculture. This is a highly efficient utilization method.

[0003] In existing silage baling and wrapping machines on the market, a large amount of forage scatters from the bottom of the baling bin and wrapping frame during operation. This forage cannot be collected and utilized, resulting in low silage utilization and unnecessary waste. In addition, forage also leaks into the conveyor belt during transport. The more forage leaks into the conveyor belt, the more it accumulates. If it is not cleaned up in time, it will cause the conveyor belt to break, affecting the stable operation and utilization rate of the silage baling and wrapping machine. Utility Model Content

[0004] This utility model provides a material leakage recovery device for a baling and wrapping machine to solve the problems of waste caused by a large amount of straw scattered under the baling and wrapping mechanism and the straw leakage into the conveyor belt not being cleaned up in time in the existing technology.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A material leakage recovery device for a baling and wrapping machine includes a material leakage return mechanism and a material leakage guide mechanism. The material leakage return mechanism consists of a material leakage recovery conveyor belt, an upper roller, a lower roller, and several guide rollers. The material leakage recovery conveyor belt is placed below the baling bin and rotating wrapping seat of the baling and wrapping machine. The material leakage recovery conveyor belt surrounds the upper roller, lower roller, and guide rollers. The upper roller is adjacent to the roller shaft of the baling bin. The material leakage guide mechanism consists of two arc-shaped guide plates, a material leakage disc, and a material-pushing rod. The two arc-shaped guide plates are respectively installed on the left and right sides of the rotating wrapping seat. The material leakage disc is fixed on the rotating wrapping seat and has a U-shaped structure. The material-pushing rod is connected to the frame of the baling and wrapping machine and is located above the material leakage disc.

[0007] The lower roller of the aforementioned material return mechanism is an anti-accumulation roller, which consists of a central rotating shaft and several circular rods in the circumferential direction. Spiral blades are set between the rotating shaft and the circular rods. The lower roller of the feeding conveyor belt is also an anti-accumulation roller.

[0008] The working principle of this utility model is as follows: When the baling and wrapping machine is running, the feeding conveyor belt delivers straw to the baling bin. The baling motor drives the rollers to rotate, causing the straw to tumble and rotate in a circular motion to form a round bale. Then, the round bale is tied by the rope feeding mechanism. After tying, the round bale rolls from the movable bin door onto the rotating wrapping seat. The rotating motor drives the rotating wrapping seat to rotate, pulling open the stretch film on the film conveyor and wrapping it around the round bale. At the same time, the rollers of the baling bin drive the adjacent spillage recovery conveyor belt to rotate along the upper roller, lower roller, and guide roller, and the rotating wrapping seat... During rotation, the straw that falls off the machine falls onto the leakage disc through the left and right arc-shaped guide plates. The U-shaped disc rotates together with the wrapping frame. When the U-shaped notch rotates to a position above the rotating leakage conveyor belt, the fixed baffle bar pulls the straw that has fallen onto the U-shaped disc along the circular plates on both sides of the wrapping frame down and onto the rotating anti-leakage conveyor belt below. The conveyor belt then sends the straw to the baler's hopper. The straw that falls off during the baling process also falls onto the leakage recovery conveyor belt. The leakage recovery conveyor belt sends the straw back up to the baling hopper for recycling and continued baling and wrapping operations.

[0009] The lower rollers of both the material leakage recovery conveyor belt and the upper rollers of the feeding conveyor belt of this utility model are made of anti-accumulation rollers. During operation, the grass that leaks into the conveyor belt falls into the roller through the gap between the round rods. The rotating spiral blades inside the anti-accumulation roller can push the leaked material out, preventing the grass from accumulating too much and damaging the conveyor belt.

[0010] This utility model is a leak recovery device specifically developed for baling and wrapping machines. It does not require additional power and cleverly utilizes the power of the rollers in the baling bin to realize the leakage recovery conveyor belt drive, thereby achieving automatic recovery of leaked material during the baling and wrapping process. It has the advantages of ingenious design, low cost, and environmental protection and high efficiency. Attached Figure Description

Detailed Implementation

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a material leakage recovery device for a baling and wrapping machine includes a material leakage return mechanism and a material leakage guide mechanism. The material leakage return mechanism consists of a material leakage recovery conveyor belt 4, an upper roller 5, a lower roller 6, and several guide rollers 7. The material leakage recovery conveyor belt 4 is placed below the baling bin 1 and the rotating wrapping seat 2 of the baling and wrapping machine. The material leakage recovery conveyor belt 4 surrounds the upper roller 5, the lower roller 6, and the guide rollers 7. The upper roller 5 is adjacent to the roller shaft 11 of the baling bin 1. The material leakage guide mechanism consists of two arc-shaped guide plates 8, a material leakage disc 8, and a material-pulling rod 10. The two arc-shaped guide plates 8 are respectively installed on the left and right sides of the rotating wrapping seat 2. The material leakage disc 8 is fixed on the rotating wrapping seat 2 and has a U-shaped structure. The material-pulling rod 9 is connected to the frame of the baling and wrapping machine and is located above the material leakage disc 8. The lower roller 6 of the material return mechanism is an anti-accumulation roller. The anti-accumulation roller consists of a central rotating shaft 12 and several circular rods 13 in the circumferential direction. A spiral blade 14 is set between the rotating shaft 12 and the circular rods 13. The lower roller 31 of the feeding conveyor belt 3 is also an anti-accumulation roller.

[0018] The working principle of this utility model is as follows: When the baling and wrapping machine is running, the feeding conveyor belt delivers straw to the baling bin. The baling motor drives the rollers to rotate, causing the straw to tumble and rotate in a circular motion to form a round bale. Then, the round bale is tied by the rope feeding mechanism. After tying, the round bale rolls from the movable bin door onto the rotating wrapping seat. The rotating motor drives the rotating wrapping seat to rotate, pulling open the stretch film on the film conveyor and wrapping it around the round bale. At the same time, the rollers of the baling bin drive the adjacent spillage recovery conveyor belt to rotate along the upper roller, lower roller, and guide roller, and the rotating wrapping seat... During rotation, the straw that falls off the machine falls onto the leakage disc through the left and right arc-shaped guide plates. The U-shaped disc rotates together with the wrapping frame. When the U-shaped notch rotates to a position above the rotating leakage conveyor belt, the fixed baffle bar pulls the straw that has fallen onto the U-shaped disc along the circular plates on both sides of the wrapping frame down and onto the rotating anti-leakage conveyor belt below. The conveyor belt then sends the straw to the baler's hopper. The straw that falls off during the baling process also falls onto the leakage recovery conveyor belt. The leakage recovery conveyor belt sends the straw back up to the baling hopper for recycling and continued baling and wrapping operations.

[0019] The lower rollers of both the material leakage recovery conveyor belt and the upper rollers of the feeding conveyor belt of this utility model are made of anti-accumulation rollers. During operation, the grass that leaks into the conveyor belt falls into the roller through the gap between the round rods. The rotating spiral blades inside the anti-accumulation roller can push the leaked material out, preventing the grass from accumulating too much and damaging the conveyor belt.
