[0019] To this end, as shown in Figure 1 、 Figure 2 The present application provides a full-automatic high-efficiency bundling equipment, which comprises a bundling host 1 and a throwing structure 5. A conveying structure 3 is arranged at the feeding port of the bundling host 1, and the conveying structure 3 is used for straw conveying.

In order to meet the throwing and separating operation, the throwing distance needs to be adjusted. When adjusting the guide plate 57 and the air jet nozzle 513, the first nut 54 on the sliding screw rod 56 is loosened, the sliding screw rod 56 can freely slide in the sliding hole 52, the guide plate 57 can freely slide on the support frame 51, and after the appropriate throwing distance is adjusted, the position of the guide plate 57 is fixed by locking the first nut 54, and the throwing and separating distance is adjusted. The B surface of the guide plate 57 is a curved arc surface, and the separated straw, wherein the unqualified straw slides along the B surface of the guide plate 57 and falls. Due to the curved arc surface of the B surface, better flow guiding effect can be achieved, and better cooperation can be achieved to separate the straw with different water contents.

[0022] As shown in the figure,Figure 3 、 Figure 6 As shown in FIG. 1, the flow limiting plate 511 is provided with a flat push structure 4, the flow limiting plate 511 is provided with a movable seat 47, the movable plate 41 is rotatably connected between the two movable seats 47 through a connecting shaft, a supporting plate 46 is slidably arranged on the top side of the movable plate 41, the bottom side of the supporting plate 46 is a reverse triangular structure, a limiting sliding groove 42 is formed in the supporting plate 46, and a limiting column 44 is fixed on the top side of the movable plate 41 and slidably arranged in the limiting sliding groove 42. In order to ensure that the straw is evenly spread when being thrown, and the thickness of the straw in the rolling width is uniform, the thickness of the straw feeding is limited by the distance between the movable plate 41 and the surface of the conveying belt 35 on the conveying structure 3 during the straw feeding process. In order to ensure the stability of the movement of the supporting plate 46, the limiting column 44 is arranged, and the two limiting columns 44 move relatively in the limiting sliding groove 42 during the movement of the supporting plate 46, and the reciprocating movement of the movable plate 41 is effectively limited by the limiting sliding grooves 42 on both sides. During the straw spreading, the straw accumulated above the movable plate 41 is pushed downward by the supporting plate 46 on the movable plate 41, and during the movement of the movable plate 41, the bottom triangular structure of the movable plate 41 can push the straw at the bottom of the movable plate 41 downward and spread to both sides, realizing the feeding and spreading of the straw, avoiding the concentration of straw throwing, and dispersing the impact of the movable plate 41 at the bottom for the accumulated straw, which can improve the situation of baling and feeding the straw in the baling state, and better maintain the feeding state. As shown in FIG. 1, Figure 7 、 Figure 8 The supporting plate 46 is fixed with a push head 48, the push head 48 is arranged corresponding to the bottom triangular side of the supporting plate 46, the top of the movable plate 41 is equipped with a push flat motor 49, the output shaft of the push flat motor 49 is equipped with a rotating disc 43, the top side of the rotating disc 43 is eccentrically connected with a crank connecting rod 45, and the other end of the crank connecting rod 45 is connected to the middle top side of the supporting plate 46 through a rotating pin. The bottom side of the movable plate 41 is equipped with a supporting wheel 410. In the process of spreading the straw within the thickness limit, through the pushing motor 49 operation, the rotating disc 43 can be driven to rotate, and under the operation of the crank connecting rod 45, the supporting plate 46 can be driven to move, and under the limiting action of the limiting column 44, the supporting plate 46 realizes up-down reciprocating conveying, and in the process of up-down reciprocating operation of the supporting plate 46, the corresponding bottom straw is pushed downward and spread to both sides, realizing the feeding and spreading of the straw, and through the heightening cooperation of the pushing head 48, it can better cope with the stacked high straw, avoid the movement of the excess straw over the movable plate 41, and better spread the stress surface of the straw, and achieve better spreading and pushing effect; By setting the supporting wheel 410, when the bundling host 1 and the conveying structure 3 are matched for use, the supporting wheel 410 is arranged on the side of the conveying frame 31 of the conveying structure 3, and the distance between the movable plate 41 and the conveying belt 35 is limited by the supporting wheel 410, which limits the thickness of the feeding, and also facilitates the support and lifting of the flat pushing structure 4 itself.

[0023] As shown in Figure 3 , Figure 6 , the conveying structure 3 comprises a conveying frame 31, the conveying frame 31 is provided with conveying rollers at the upper and lower ends, and the conveying belt 35 is cooperatively arranged on the two conveying rollers, the top sides of the conveying frame 31 are respectively provided with guardrails 32, the middle inner sides of the guardrails 32 are fixedly provided with guide plates 34, the two guide plates 34 are arranged in an eight-shaped manner, the two guide plates 34 are located below the taper angle position of the supporting plate 46, the supporting wheel 410 at the bottom side of the movable plate 41 is arranged on the side frame of the conveying frame 31, and the bottom side of the conveying frame 31 is provided with a conveying motor 33, and the conveying motor 33 is used to drive one of the conveying rollers; In the feeding process, the straw is manually picked and sent to the bottom side of the conveying belt 35, and under the driving action of the conveying motor 33 on the conveying roller, the conveying belt 35 can be rotated to realize the climbing and conveying of the straw on the conveying belt 35, and the two guardrails 32 are arranged to prevent the straw from sliding and falling during the climbing process; In order to have better spreading effect on the straw, the two guide plates 34 on the sides are used to gather the straw on the conveying belt 35 to the middle part of the conveying belt 35, and the gathered straw is located in the middle area of the conveying belt 35, and after rising, the straw can be spread to both sides under the reciprocating impact and dispersion of the supporting plate 46, so as to realize the regular conveying of the straw and avoid the deviation of the straw conveying, which causes the bundling process, the uneven density of each position, the loose and unformed bundling straw, and affects the quality of finished products.

[0024] The conveying channel is formed between the movable plate 41 and the upper surface of the conveying belt 35, and the top of the conveying belt 35 of the conveying structure 3 is arranged above the inclined angle of the air jet nozzle 513. During operation, the thickness of the straw feeding can be limited through the conveying channel formed between the movable plate 41 and the upper surface of the conveying belt 35, so that the thickness of the straw along the throwing path is relatively uniform during the throwing process, ensuring the effectiveness of the throwing operation. At the same time, through paving, it is more convenient for the straw to enter the baling main machine 1 for baling into a roll, and the overall compactness of the baled straw is relatively uniform.

[0025] Working principle: during the baling and film wrapping process of the straw, the straw is conveyed by the conveying structure 3 and sent into the baling main machine 1. The straw is rolled into a roll through the cooperation of the roller cutter and the belt in the baling main machine 1. After rolling, the baled straw is pushed out of the baling main machine 1 and falls on the film wrapping structure 2. The baled straw is wrapped by the rotating protective film to realize the baling and film wrapping operation of the straw; During the baling process, the dryness of the straw needs to be ensured. Due to the different water content of the straw, the weight of the straw is different. The water content of the straw stored for a short period of time should be maintained between 12%-15%. If the water content of the straw is too high, the quality of the straw itself is heavier. During the baling and conveying process of the straw, the straw is screened through the throwing channel formed between the guide plate 57 and the flow limiting plate 511 before entering the baling main machine 1. During the throwing process, due to the different water content of the straw, the gravity of the straw with high water content is large. Under the action of the same throwing force, the straw with high water content falls earlier, so that the straws with different water contents are separated during the throwing process. The straw with qualified water content can enter the baling main machine 1 through the throwing channel to realize baling. The straw with unqualified water content cannot pass through the throwing channel and cannot enter the baling main machine 1 for baling operation, so as to ensure the water content of the baled straw and avoid mold damage caused by high water content. During the throwing process of the straw, the constant pressure gas is sprayed out through the air jet nozzle 513, so that the conveyed straw is pushed into the throwing channel formed by the A surface of the guide plate 57 and the bottom side of the flow limiting plate 511 under the pushing of the constant pressure gas. The straw conveyed in different areas can be pushed at a constant pressure through different air jet nozzles 513, so as to ensure that the straw is uniformly stressed during the throwing process and ensure the throwing screening effect. Through the throwing operation, not only the straw with water content can be screened, but also the large particles in the straw can be screened. The mixing of large particles can be avoided. At the same time, during the air blowing feeding process, the dry straw enters the baling main machine 1 in a loose state, so that the loose straw can be better uniformly rolled and formed in the baling main machine 1, avoiding accumulation and rolling. The compactness of the rolled and formed straw is more uniform, and the forming shape is better.

[0026] After the throwing and separating, the separated dry straw enters into the bundling main machine 1 through the throwing channel. In order to prolong the sliding path of the straw, the throwing channel and the bundling main machine 1 are overlapped through the shifting plate 58 when the distance between the guide plate 57 and the feeding port of the bundling main machine 1 is different, so as to ensure the straw to slide into the bundling main machine 1 effectively and avoid the separated dry straw from separating; Since the throwing and separating distance of different types of straw is limited by the quality of the straw, in order to meet the throwing and separating operation, the throwing distance needs to be adjusted. When adjusting the distance between the guide plate 57 and the air nozzle 513, the first nut 54 on the sliding screw 56 is loosened, so as to realize the free sliding of the sliding screw 56 in the sliding hole 52 and the free sliding of the guide plate 57 on the support frame 51. After the appropriate throwing distance is adjusted, the first nut 54 is locked, so as to fix the position of the guide plate 57 and adjust the throwing and separating distance. The B surface of the guide plate 57 is a curved arc surface. The separated straw, including the unqualified straw, slides along the B surface of the guide plate 57 and falls. Since the B surface is a curved arc surface, better flow guiding effect can be achieved, and the straw with different water content can be better separated. During operation, in order to provide directional stable constant pressure gas thrust for the throwing process, the second nut 515 is loosened, and the swinging plate 512 swings under the cooperation of the swinging shaft 514, so as to adjust the orientation of the air nozzle 513, so as to better apply to the throwing operation of the straw after the throwing channel is changed. The front and back adjustment can achieve better throwing and separating effect. During operation, the gas pump is connected through the gas pump connecting head at one end of the connecting frame 516. The gas is pumped by the gas pump, enters the main flow pipe 519, is separated by the shunt pipe 518, and is sprayed out of the air nozzle 513. Stable throwing power can be provided for the throwing operation to separate the straw with different water content.

[0027] In order to ensure the uniformity of the straw spreading of the thrown straw, and at the same time, through the spreading, the thickness of the straw in the bundling and rolling width is uniform. During the straw feeding process, the thickness of the straw feeding is limited by the distance between the movable plate 41 and the surface of the conveying belt 35 on the conveying structure 3. In order to ensure the stability of the movement of the supporting plate 46, the limiting column 44 is arranged. During the movement of the supporting plate 46, the two limiting columns 44 move relatively in the limiting sliding groove 42, and the reciprocating movement of the movable plate 41 is effectively limited by the limiting sliding grooves 42 on both sides. When the straw is spread, the straw accumulated above the movable plate 41 is pushed down by the reciprocating pushing of the supporting plate 46 on the movable plate 41. During the movement of the supporting plate 46, the bottom triangular structure of the supporting plate 46 can push the corresponding straw at the bottom of the movable plate 41 downward and spread it to both sides, realizing the feeding and spreading of the straw, avoiding the concentration of straw feeding, and dispersing the impact of the movable plate 41 at the bottom of the accumulated straw. It can scatter the compacted straw, improve the situation of compacted straw baling and feeding, and better maintain the feeding state. During the operation of limiting the thickness of the straw spreading, the rotating disc 43 is driven to rotate by the pushing motor 49, and the supporting plate 46 is driven to move under the operation of the crank connecting rod 45. Under the limiting action of the limiting column 44, the supporting plate 46 realizes up-down reciprocating conveying. During the up-down reciprocating operation of the supporting plate 46, the corresponding straw at the bottom is pushed downward and spread to both sides, realizing the feeding and spreading of the straw. Through the heightening cooperation of the push head 48, it can better cope with the high stacked straw, avoid the movement of excess straw over the movable plate 41, and have a better spreading force surface for the straw, achieving better spreading and pushing effect. By setting the supporting wheel 410, the supporting wheel 410 can be placed on the side of the conveying frame 31 of the conveying structure 3 when the baling host 1 and the conveying structure 3 are matched for use. The supporting wheel 410 can limit the distance between the movable plate 41 and the top of the conveying belt 35, realize the limitation of the feeding thickness, and also facilitate the support and lifting of the flat pushing structure 4 itself.

[0028] During the feeding process, the straw is manually picked and sent to the bottom side of the conveying belt 35. Under the driving action of the conveying motor 33 on the conveying roller, the rotation of the conveying belt 35 can be realized, realizing the climbing conveying of the straw falling on the conveying belt 35. By setting the two side guards 32, the straw is prevented from sliding and falling during climbing; In order to achieve better spreading effect of the straw, the straw on the conveying belt 35 is gathered to the middle part of the conveying belt 35 by the two side guide plates 34. After gathering, the straw is located in the middle area of the conveying belt 35. After rising, the straw can be spread to both sides under the reciprocating impact dispersion of the supporting plate 46, realizing the regular conveying of the straw, avoiding the deviation of the straw conveying during baling, and the uneven density of each position, leading to loose and unformed baling straw, affecting the quality of finished products.

[0029] When working, the conveying channel is formed between the movable plate 41 and the upper surface of the conveying belt 35, the thickness of the straw feeding can be limited, so that the thickness of the straw along the throwing path is relatively balanced during the throwing process, and the throwing operation is effective. At the same time, through paving, it is more convenient for the straw to enter the baling host 1 for baling into a roll, and the overall compactness of the baled straw is relatively balanced.

[0030] During conveying, the straw is manually picked and sent to the bottom side of the conveying belt 35, the conveying roller is driven by the conveying motor 33 to rotate the conveying belt 35, the straw is conveyed upward, and the two side guardrails 32 are arranged to prevent the straw from sliding off during the upward conveying process. During conveying, the straw is gathered to the middle of the conveying belt 35 by the two side guide plates 34, and the straw on the conveying belt 35 is gathered to the middle of the conveying belt 35 by the two side guide plates 34. After the subsequent upward conveying process, the pushing motor 49 operates to drive the rotating disc 43 to rotate, and the bracket 46 reciprocates up and down under the cooperation of the crank connecting rod 45. During the reciprocating operation of the bracket 46, the straw gathered in the middle of the conveying belt 35 can be pushed downward and spread out under the reciprocating impact dispersion of the bracket 46 and the height increase of the push head 48. The bottom triangular structure of the bracket 46 can push the straw at the bottom of the bracket 46 downward and spread it to both sides, realizing the feeding and spreading of the straw. By spreading the straw to both sides, the straw is regularly conveyed. After the thickness of the straw is limited, the conveying channel is formed between the movable plate 41 and the upper surface of the conveying belt 35, which can uniformly disperse the straw, and the limited thickness of the straw is thrown and separated during conveying. When throwing and separating, the constant pressure gas is sprayed out through the air nozzle 513 to push the conveyed straw into the throwing channel formed by the guide plate 57 and the flow limiting plate 511, realizing the separation of the straw. Because the water content of the straw is different, the straw with higher water content has heavier quality, and under the action of the same throwing force, it will drop earlier, thereby realizing the separation of the straw with different water content during the throwing process. The straw with qualified water content can pass through the throwing channel and enter the baling host 1 for baling, while the straw with unqualified water content cannot pass through the throwing channel, so as to ensure the water content of the baled straw and avoid mold damage.

[0031] In the process of straw throwing, in order to deal with different types of straw baling, the second nut 515 can be loosened, and under the cooperation of the swing shaft 514, the orientation of the air jet nozzle 513 can be adjusted to adapt to the change of the throwing channel. Also, the first nut 54 on the sliding screw 56 can be loosened to realize the free sliding of the sliding screw 56 in the sliding hole 52, so as to realize the free sliding of the guide plate 57 on the support frame 51, adjust the appropriate throwing distance, and realize the diversion of straw with different water content.

[0032] The spreading and thickness limiting operation of the feeding straw by the flat pushing structure 4 can avoid the accumulation of straw feeding. The material can be spread by the pushing of the supporting plate 46, which can avoid the concentrated feeding of straw. By spreading the straw, the feeding along the width of the baling roll can be ensured, and the straw can be better spread along the width of the baling roll. After the straw is spread, the straw is thrown by the throwing structure 5. After the thickness limiting process by the flat pushing structure 4, the throwing process of the straw by the throwing structure 5 can be more uniform, and better throwing effect can be achieved. After the straw is thrown and separated, not only the water content of the straw can be screened, but also the large particle solids in the straw can be screened, which can avoid the mixing of large particle solids. At the same time, in the process of air blowing and feeding, the dry straw enters the baling host 1 in a loose state, so that the loose straw can be better uniformly rolled and formed when entering the baling host 1, avoiding accumulation and concentrated rolling, which can ensure that the density of the rolled and formed straw is more uniform, and the formed shape is better.

[0033] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
