Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a fully automatic and efficient baling device. Background Technology

[0002] With the continuous advancement of agricultural modernization, the storage of crop straw has become an urgent problem to be solved in agricultural production. When storing straw, straw balers are used to bale and wrap excess straw to achieve short-term collection and storage for later use. During the baling process, dry straw needs to be fed into the baling machine via a conveyor belt, where it is rolled, wrapped, and stored in the rollers. A search revealed that CN 119256780 A discloses an automatic straw baler, including a baling cart and side plates mounted on the baling cart. The baling cart contains a compression assembly, and an automatic pickup assembly is located between the side plates. A conveyor belt is located on one side of the automatic pickup assembly, a pressing cylinder is located on one side of the baling cart, and a rope-tying assembly is located on one side of the pressing cylinder. In this invention, an activating rotary motor drives blades to push straw from the ground onto the conveyor belt. The conveyor belt transports the straw to a discharge ramp where it falls into the collection trough of the baling cart. Subsequently, a servo motor is activated to drive an extrusion disc to push the straw from the collection trough into the pressing cylinder. After the extrusion is completed, the rolled straw is ejected and wrapped.

[0003] In practical use, the moisture content of straw has a significant impact on its baling quality and subsequent utilization. Existing balers lack effective means of controlling moisture content and cannot perform rough screening of straw before baling, resulting in a large amount of straw with unqualified moisture content being mixed in. Excessive moisture content in the baled straw can lead to problems such as mold and damage during the baling process, affecting the overall quality. At the same time, the uniformity of straw spreading during the baling process directly affects the density and uniformity of the baled structure. Straw often piles up together, and the inability to spread it evenly not only leads to uneven density of the baled structure but may also affect the normal operation of the baler due to excessive local accumulation, or even damage the equipment. Based on this, the present invention discloses a fully automatic and efficient baling device. Summary of the Invention

[0004] To address the problem mentioned in the background art that existing balers lack effective means of controlling moisture content, are unable to perform rough screening of straw before baling, resulting in a large amount of straw with unqualified moisture content being mixed in, and that excessively high moisture content of baled straw can lead to problems such as mold and damage during the baling process.

[0005] This invention provides a fully automatic and efficient baling device, including a baling host and a throwing structure.

[0007] As a further improvement to this technical solution, an inclined groove is provided on the top arc-shaped A surface of the guide plate, and a toggle plate is hinged in the inclined groove. The bottom side of the toggle plate is placed inside the feed inlet of the bundling host.

[0008] As a further improvement to this technical solution, the B-side of the guide plate is a curved arc surface, a sliding lug is fixed on the bottom side of the guide plate, and a sliding screw with external thread is fixed on both sides of the sliding lug. The sliding screws on both sides of the sliding lug are slidably disposed in the sliding holes inside the support frame, wherein the bottom side of the guide plate is slidably disposed on the top side of the support frame, and a first nut is fitted on the sliding screw.

[0009] As a further improvement to this technical solution, swing shafts are respectively installed on both sides of the swing plate, and the two swing shafts are respectively set through the mounting holes of the swing frame, and a second nut is rotatably installed on the swing shafts through threaded engagement.

[0010] As a further improvement to this technical solution, a connecting frame is fixed to the bottom side of one end of the support frame, a main flow pipe is installed between the two connecting frames, a branch pipe is connected to the main flow pipe, and one end of the branch pipe passes through the swing plate. The main flow pipe and the jet nozzle are connected through the branch pipe, and an air pump connector is installed at one end of the connecting frame.

[0011] As a further improvement to this technical solution, a flat-push structure is installed on the flow-limiting plate. The flat-push structure includes a movable plate. A movable seat is installed on the flow-limiting plate. The movable plate is rotatably installed between the two movable seats through a connecting shaft. A support plate is slidably arranged on the top side of the movable plate. The bottom side of the support plate has an inverted triangular structure. A limit groove is opened in the support plate. A limit post is fixed on the top side of the movable plate. The limit post is slidably arranged in the limit groove.

[0012] As a further improvement to this technical solution, a push head is fixed on the pallet, and the push head is arranged on the side of the bottom triangular side of the pallet. A flattening motor is mounted on the top and bottom side of the movable plate, and a rotating disk is mounted on the output shaft of the flattening motor. A crank connecting rod is connected and mounted on the top eccentric position of the rotating disk, and the other end of the crank connecting rod is connected to the top side of the middle of the pallet through a rotating pin. Support wheels are fitted to the bottom sides of the movable plate.

[0013] As a further improvement to this technical solution, the conveying structure includes a conveying frame, with conveying rollers mounted at both the upper and lower ends of the conveying frame. A conveyor belt is fitted onto the two conveying rollers. Protective railings are fixed to the top two side frames of the conveying frame. A guide plate is fixed to the inner side of the middle of the protective railing. The two guide plates are arranged in a figure-eight shape and are located below the cone angle of the support plate. The support wheels on the bottom side of the movable plate are mounted on the side frame of the conveying frame. A conveying motor is installed on the bottom side of the conveying frame, and the conveying motor is used to drive one of the conveying rollers.

[0014] As a further improvement to this technical solution, a conveying channel is formed between the movable plate and the upper surface of the conveyor belt, and the top of the conveyor belt of the conveying structure is positioned above the tilt angle of the jet nozzle.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This fully automatic and efficient baling equipment uses a throwing structure to screen the moisture content of straw, effectively preventing mold and damage caused by excessive moisture. During the throwing process, straw with higher moisture content falls earlier due to its greater weight and is screened out; while qualified straw smoothly passes through the throwing channel and enters the baling host. This screening mechanism not only improves the baling quality but also reduces the defect rate in subsequent processing. In addition, while screening for moisture content, the throwing structure can also separate large solid particles in the straw, preventing them from being mixed into the baling process. The screening mechanism ensures that the straw entering the baling host is purer, further improving the quality of the baled straw. By using a flat-push structure to spread and limit the thickness of the straw, the straw accumulation during feeding is avoided, and the straw is spread evenly along the width of the bundle. Through the reciprocating motion of the movable plate and the pallet, the straw is pushed downward and spread evenly. The triangular structure at the bottom of the pallet further realizes the spreading to both sides, which improves the feeding state of the straw that is compacted and piled up, and improves the uniformity and stability of the baling operation. The equipment also uses the combined action of the flat pushing structure and the throwing structure to allow the dry straw to enter the baling host in a loose state, which can better and more evenly roll and shape it, avoid the accumulation and concentrated rolling, ensure that the density of the rolled straw is more uniform, the shape is better, and improve the quality and consistency of baling.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Therefore, such as Figure 1 , Figure 2 As shown, the present invention provides a fully automatic and efficient baling device, including a baling host 1 and a throwing structure 5. A conveying structure 3 is provided in the feed inlet direction of the baling host 1 for conveying straw. The throwing structure 5 is installed between the baling host 1 and the conveying structure 3 for dispersing and throwing straw. A flat pushing structure 4 is installed on the throwing structure 5. A wrapping structure 2 is installed at the discharge port of the baling host 1 for wrapping the baled straw. During the baling and wrapping process of straw, the straw is conveyed by the conveying structure 3 and fed into the baling host 1. The straw is rolled into a roll by the roller cutter and belt in the baling host 1. After being rolled, the rolled straw is pushed out of the baling host 1 and falls onto the wrapping structure 2. The straw is wrapped by rotation and protective film. like Figure 3 , Figure 4 , Figure 5 As shown, the throwing structure 5 includes a support frame 51, a guide plate 57 is slidably disposed on the support frame 51, a transverse connecting rod 53 is fixed on one side of the guide plate 57, a vertical support rod 510 is vertically installed on the transverse connecting rod 53, and a flow limiting plate 511 is fixed at the top of the vertical support rod 510. like Figure 5 As shown, the bottom side arc surface of the flow limiting plate 511 is located directly above the top A surface of the guide plate 57, forming a throwing channel between the flow limiting plate 511 and the guide plate 57. During the baling process, it is necessary to ensure the dryness of the straw. Since the moisture content of straw varies, the weight of straw varies. For straw stored for a short period of time, the moisture content should be maintained between 12% and 15%. Straw with a higher moisture content is heavier. During the baling and conveying process, before the straw enters the baling host 1, it is screened through the throwing channel formed between the guide plate 57 and the flow limiting plate 511. During the throwing process, due to the different moisture contents of the straw, the straw with higher moisture content has greater weight. Under the same throwing force, the straw with higher moisture content falls earlier, causing the straws with different moisture contents to separate during the throwing process. Straws with the correct moisture content can enter the baling host 1 through the throwing channel to be baled, while straws with the incorrect moisture content cannot enter the baling host 1 for baling. This ensures that the moisture content of the baled straw is within acceptable limits and avoids mold and damage caused by high moisture content.

[0020] like Figure 4 As shown, a swing frame 517 is installed on the top side of one end of the support frame 51, and a swing plate 512 is provided between the two swing frames 517. An air nozzle 513 is installed on the swing plate 512, and the air nozzle 513 is oriented toward the throwing channel. During operation, constant pressure gas is sprayed out through the jet nozzle 513 during the throwing process, so that the conveyed straw is pushed into the throwing channel formed by the A side of the guide plate 57 and the bottom side of the flow limiting plate 511 under the constant pressure gas. The constant pressure push can be achieved by the jet nozzle 513 at different positions to convey straw in different areas, so as to ensure that the straw is subjected to uniform force during the throwing process and to ensure the throwing and screening effect. By throwing the straw, not only can the moisture content of the straw be screened, but also the large solid particles in the straw can be screened to avoid the mixing of large solid particles. At the same time, during the blowing and feeding process, the dry straw enters the baling host 1 in a loose state, so that the loose straw can be rolled and shaped more evenly in the baling host 1, avoiding the accumulation and concentrated rolling, and ensuring that the density of the rolled straw is more uniform and the shape is better.

[0021] like Figure 5 As shown, the top arc-shaped A surface of the guide plate 57 is provided with an inclined groove 520, and a toggle plate 58 is hinged in the inclined groove 520. The bottom side of the toggle plate 58 is placed in the feed inlet of the bundling host 1. During operation, after being thrown and separated, the separated dry straw enters the baling host 1 through the throwing channel. In order to extend the downward path of the straw, so that when the guide plate 57 is at a different distance from the feed inlet of the baling host 1, the overlapping between the straw throwing channel and the baling host 1 can be achieved by the actuating plate 58, so as to ensure that the straw effectively slides into the baling host 1 and avoids the separated dry straw from falling off. like Figure 4 , Figure 5As shown, the B-side of the guide plate 57 is a curved arc surface. A sliding lug 59 is fixed on the bottom side of the guide plate 57. A sliding screw 56 with external threads is fixed on both sides of the sliding lug 59. The sliding screws 56 on both sides of the sliding lug 59 are slidably disposed in the sliding holes 52 inside the support frame 51. The bottom side of the guide plate 57 is slidably disposed on the top side of the support frame 51. A first nut 54 is fitted on the sliding screw 56. Since the throwing and separation distance of different types of straw is limited by its own mass, the throwing distance needs to be adjusted in order to meet the throwing and separation operation during the throwing process. When adjusting between the guide plate 57 and the air nozzle 513, the first nut 54 on the sliding screw 56 can be loosened to allow the sliding screw 56 to slide freely in the sliding hole 52, and the guide plate 57 to slide freely on the support frame 51. After adjusting the appropriate throwing distance, the position of the guide plate 57 can be fixed by locking the first nut 54, thereby adjusting the throwing and separation distance. The B side of the guide plate 57 is a curved arc surface. After separation, the unqualified straw slides down along the B side of the guide plate 57. Since the B side is a curved arc surface, it can achieve better flow guidance and better cooperate to separate straws with different moisture contents. like Figure 4 As shown, swing shafts 514 are respectively installed on both sides of the swing plate 512. The two swing shafts 514 are respectively installed through the mounting holes of the swing frame 517, and a second nut 515 is rotatably installed on the swing shaft 514 through threaded engagement. During operation, in order to provide a directional and stable constant pressure gas thrust to the throwing process, the second nut 515 can be loosened. With the cooperation of the swing shaft 514, the swing plate 512 can be swinged, thereby adjusting the orientation of the jet nozzle 513. This is so that it can be better applied to the throwing operation of straw after the throwing channel is changed. It can be adjusted in a coordinated manner to achieve a better throwing and separation effect. like Figure 4 As shown, a connecting frame 516 is fixed to the bottom side of one end of the support frame 51, and a main pipe 519 is installed between the two connecting frames 516. A branch pipe 518 is connected to the main pipe 519, and one end of the branch pipe 518 passes through the swing plate 512. The main pipe 519 and the jet nozzle 513 are connected through the branch pipe 518, and an air pump connector is installed at one end of the connecting frame 516. During operation, the air pump is connected to the air pump connector at one end of the connecting frame 516. The air pump pumps air, which enters through the main pipe 519, is then diverted through the diversion pipe 518, and is ejected through the jet nozzle 513. This provides stable throwing power for the throwing operation, enabling the separation of straw with different moisture contents.

[0022] like Figure 3 , Figure 6 As shown, a flat-push structure 4 is installed on the flow-limiting plate 511. The flat-push structure 4 includes a movable plate 41. A movable seat 47 is installed on the flow-limiting plate 511. The movable plate 41 is rotatably installed between the two movable seats 47 via a connecting shaft. A support plate 46 is slidably provided on the top side of the movable plate 41. The bottom side of the support plate 46 has an inverted triangular structure. A limiting groove 42 is opened in the support plate 46. A limiting post 44 is fixed on the top side of the movable plate 41. The limiting post 44 is slidably provided in the limiting groove 42. To ensure that the straw is spread evenly during the throwing process, and to ensure that the thickness of the straw is uniform within the baling and rolling width, the thickness of the straw is limited by the distance between the movable plate 41 and the surface of the conveyor belt 35 on the conveying structure 3 during the straw feeding process. In order to ensure the stability of the movement of the pallet 46, limiting posts 44 are set. During the movement of the pallet 46, the two limiting posts 44 move relative to each other in the limiting groove 42, and the reciprocating movement of the movable plate 41 is effectively limited by the limiting grooves 42 on both sides. When spreading straw, the reciprocating push of the pallet 46 on the movable plate 41 pushes the straw piled higher than the movable plate 41 downwards. During the movement of the movable plate 41, the triangular structure at the bottom of the movable plate 41 can push the straw corresponding to the bottom of the movable plate 41 downwards and spread it to both sides, realizing the feeding and spreading of straw, avoiding the concentrated feeding of straw. For the straw that is compacted and piled up, the impact of pushing the bottom of the movable plate 41 can disperse the compacted straw and break it up. This can improve the situation of straw being bundled and fed in a compacted state and better maintain the feeding state. like Figure 7 , Figure 8 As shown, a push head 48 is fixed on the support plate 46. The push head 48 is arranged on the side of the bottom triangular side of the support plate 46. A push-flat motor 49 is assembled on the top and bottom side of the movable plate 41. A rotating disk 43 is assembled on the output shaft of the push-flat motor 49. A crank connecting rod 45 is connected and assembled at the eccentric position on the top side of the rotating disk 43. The other end of the crank connecting rod 45 is connected to the top side of the middle part of the support plate 46 through a rotating pin. Support wheels 410 are respectively installed on the bottom side of the movable plate 41; During the process of spreading and limiting the thickness of straw, the operation of the leveling motor 49 can drive the rotating disk 43 to rotate. With the operation of the crank connecting rod 45, the pallet 46 can move. Under the limiting action of the limiting column 44, the pallet 46 can realize up and down reciprocating transport. During the up and down reciprocating operation of the pallet 46, the straw corresponding to the bottom is pushed downward and spread to both sides, realizing the feeding and spreading of straw. With the increase of the height of the push head 48, it can better deal with the stack of straw that is too high, prevent excess straw from moving over the moving plate 41, and provide a better spreading force surface for straw, achieving a better spreading and pushing effect. By setting the support wheel 410, when the bundling host 1 and the conveying structure 3 are used together, the support wheel 410 can be placed on the side of the conveying frame 31 of the conveying structure 3. The support wheel 410 can limit the distance between the movable plate 41 and the conveyor belt 35, thereby limiting the thickness of the material being fed, and also facilitates the support and lifting of the flat push structure 4 itself.

[0023] like Figure 3 , Figure 6 As shown, the conveying structure 3 includes a conveying frame 31. Conveying rollers are mounted at the upper and lower ends of the conveying frame 31. Conveying belts 35 are fitted onto the two conveying rollers. Guardrails 32 are fixed to the top two side frames of the conveying frame 31. A guide plate 34 is fixed to the inner side of the middle of the guardrail 32. The two guide plates 34 are arranged in a figure-eight shape and are located below the cone angle of the support plate 46. The support wheel 410 on the bottom side of the movable plate 41 rests on the side frame of the conveying frame 31. A conveying motor 33 is installed on the bottom side of the conveying frame 31. The conveying motor 33 is used to drive one of the conveying rollers. During the feeding process, the straw is manually picked up and fed to the bottom of the conveyor belt 35. Under the driving action of the conveyor motor 33 on the conveyor roller, the conveyor belt 35 can be rotated, and the straw falling on the conveyor belt 35 can be lifted and conveyed. By setting up guardrails 32 on both sides, the straw can be prevented from slipping and falling during the lifting process. To achieve better straw spreading, the guide plates 34 on both sides gather the straw on the conveyor belt 35 towards the center of the conveyor belt 35. The gathered straw is located in the central area of ​​the conveyor belt 35. After rising, the straw can be spread to both sides by the reciprocating impact and dispersion action of the pallet 46. This can achieve orderly straw conveying and avoid straw conveying deviation, which would cause uneven density in various positions during the baling process, resulting in loose and shapeless baled straw and affecting the quality of the finished product.

[0024] A conveying channel is formed between the movable plate 41 and the upper surface of the conveyor belt 35. The top of the conveyor belt 35 of the conveying structure 3 is positioned above the inclined angle of the air nozzle 513. During operation, the conveying channel formed between the movable plate 41 and the upper surface of the conveyor belt 35 can limit the thickness of the straw feeding, 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, by spreading, it is easier for the straw to be bundled into rolls in the baling host 1, and the overall density of the bundled straw is relatively uniform.

[0025] Working principle: During the baling and wrapping process of straw, the straw is conveyed by the conveying structure 3 and fed into the baling host 1. The straw is rolled into a roll by the roller cutter and belt in the baling host 1. After being rolled, the rolled straw is pushed out of the baling host 1 and falls onto the wrapping structure 2. The straw is wrapped by rotation and protective film. During the baling process, it is necessary to ensure the dryness of the straw. Since the moisture content of straw varies, the weight of straw varies. For straw stored for a short period of time, the moisture content should be maintained between 12% and 15%. Straw with a higher moisture content is heavier. During the baling and conveying process, before the straw enters the baling host 1, it is screened through the throwing channel formed between the guide plate 57 and the flow limiting plate 511. During the throwing process, due to the different moisture content of the straw, the straw with higher moisture content has greater weight. Under the same throwing force, the straw with higher moisture content falls earlier, causing the straws with different moisture contents to separate during the throwing process. Straws with qualified moisture content can enter the baling host 1 through the throwing channel to be baled, while straws with unqualified moisture content cannot enter the baling host 1 for baling, so as to ensure the moisture content of the baled straw and avoid mold and damage caused by high moisture content. During the throwing process of straw, constant pressure gas is sprayed out through the jet nozzle 513, so that the conveyed straw is pushed into the throwing channel formed by the A side of the guide plate 57 and the bottom side of the flow limiting plate 511 under the constant pressure gas. The constant pressure push of straw conveyed in different areas can be achieved by the jet nozzle 513 at different positions to ensure that the straw is subjected to uniform force during the throwing process and to ensure the throwing and screening effect. By throwing the straw, not only can the moisture content of the straw be screened, but also the large solid particles in the straw can be screened to avoid the mixing of large solid particles. At the same time, during the blowing and feeding process, the dry straw enters the baling host 1 in a loose state, so that the loose straw can be rolled and shaped more evenly in the baling host 1, avoiding the accumulation and concentrated rolling, and ensuring that the density of the rolled straw is more uniform and the shape is better.

[0026] After being thrown and separated, the separated dry straw enters the baling host 1 through the throwing channel. In order to extend the downward path of the straw, so that when the guide plate 57 is at a different distance from the feed inlet of the baling host 1, the overlapping between the straw throwing channel and the baling host 1 can be achieved by the actuating plate 58, so as to ensure that the straw effectively slides into the baling host 1 and avoids the separated dry straw from falling off. Since the throwing and separation distance of different types of straw is limited by its weight, the throwing distance needs to be adjusted during the throwing process in order to meet the throwing and separation operation. When adjusting between the guide plate 57 and the air nozzle 513, the first nut 54 on the sliding screw 56 can be loosened to allow the sliding screw 56 to slide freely in the sliding hole 52, and the guide plate 57 to slide freely on the support frame 51. After adjusting the appropriate throwing distance, the position of the guide plate 57 can be fixed by locking the first nut 54, thereby adjusting the throwing and separation distance. The B side of the guide plate 57 is a curved arc surface. After separation, the unqualified straw slides down along the B side of the guide plate 57. Since the B side is a curved arc surface, it can achieve better flow guidance and better cooperate to separate straws with different moisture contents. During operation, in order to provide a directional and stable constant pressure gas thrust to the throwing process, the second nut 515 can be loosened. With the cooperation of the swing shaft 514, the swing plate 512 can be swinged, thereby adjusting the orientation of the jet nozzle 513. This is so that it can be better applied to the throwing operation of straw after the throwing channel is changed. It can be adjusted in a coordinated manner to achieve a better throwing and separation effect. During operation, the air pump is connected to the air pump connector at one end of the connecting frame 516. The air pump pumps air, which enters through the main pipe 519, is then diverted through the diversion pipe 518, and is ejected through the jet nozzle 513. This provides stable throwing power for the throwing operation, enabling the separation of straw with different moisture contents.

[0027] To ensure that the straw is spread evenly during the throwing process, and to ensure that the thickness of the straw is uniform within the baling and rolling width, the thickness of the straw is limited by the distance between the movable plate 41 and the surface of the conveyor belt 35 on the conveying structure 3 during the straw feeding process. In order to ensure the stability of the movement of the pallet 46, limiting posts 44 are set. During the movement of the pallet 46, the two limiting posts 44 move relative to each other in the limiting groove 42, and the reciprocating movement of the movable plate 41 is effectively limited by the limiting grooves 42 on both sides. When spreading straw, the reciprocating push of the pallet 46 on the movable plate 41 pushes the straw piled higher than the movable plate 41 downwards. During the movement of the pallet 46, the triangular structure at the bottom of the pallet 46 can push the straw corresponding to the bottom of the movable plate 41 downwards and spread it to both sides at the same time, so as to realize the feeding and spreading of straw and avoid the concentrated feeding of straw. For the straw that is compacted and piled up, it can push the impact at the bottom of the movable plate 41 to disperse it, and can break up the compacted straw. It can improve the situation of straw being bundled and fed in a compacted state and can better maintain the feeding state. During the process of spreading and limiting the thickness of straw, the operation of the leveling motor 49 can drive the rotating disk 43 to rotate. With the operation of the crank connecting rod 45, the pallet 46 can move. Under the limiting action of the limiting column 44, the pallet 46 can realize up and down reciprocating transport. During the up and down reciprocating operation of the pallet 46, the straw corresponding to the bottom is pushed downward and spread to both sides, realizing the feeding and spreading of straw. With the increase of the height of the push head 48, it can better deal with the stack of straw that is too high, prevent excess straw from moving over the moving plate 41, and provide a better spreading force surface for straw, achieving a better spreading and pushing effect. By setting the support wheel 410, when the bundling host 1 and the conveying structure 3 are used together, the support wheel 410 can be placed on the side of the conveying frame 31 of the conveying structure 3. The support wheel 410 can limit the distance between the movable plate 41 and the conveyor belt 35, thereby limiting the thickness of the material being fed, and also facilitates the support and lifting of the flat push structure 4 itself.

[0028] During the feeding process, the straw is manually picked up and fed to the bottom of the conveyor belt 35. Under the driving action of the conveyor motor 33 on the conveyor roller, the conveyor belt 35 can be rotated, and the straw falling on the conveyor belt 35 can be lifted and conveyed. By setting up guardrails 32 on both sides, the straw can be prevented from slipping and falling during the lifting process. To achieve better straw spreading, the guide plates 34 on both sides gather the straw on the conveyor belt 35 towards the center of the conveyor belt 35. The gathered straw is located in the central area of ​​the conveyor belt 35. After rising, the straw can be spread to both sides by the reciprocating impact and dispersion action of the pallet 46. This can achieve orderly straw conveying and avoid straw conveying deviation, which would cause uneven density in different positions during the baling process, resulting in loose and shapeless baled straw and affecting the quality of the finished product.

[0029] During operation, a conveying channel is formed between the movable plate 41 and the upper surface of the conveyor belt 35, which can limit the thickness of the straw feeding. This ensures that the thickness of the straw along the throwing path is relatively uniform during the throwing process, thus guaranteeing the effectiveness of the throwing operation. At the same time, by spreading the straw, it is easier for the straw to be bundled into rolls inside the baler 1, and the overall density of the bundled straw is more uniform.

[0030] During the conveying process, the straw is manually picked up and fed to the bottom of the conveyor belt 35. The conveyor motor 33 drives the conveyor rollers to rotate the conveyor belt 35 and lift the straw. Protective railings 32 are set on both sides to prevent the straw from slipping and falling during the lifting process. During the conveying process, the guide plates 34 on both sides gather the straw to the middle of the conveyor belt 35. The guide plates 34 on both sides gather the straw on the conveyor belt 35 to the middle of the conveyor belt 35. The gathered straw is located in the middle area of ​​the conveyor belt 35. In the subsequent upward conveying process, the pusher motor 49 drives the rotating disk 43 to rotate. With the cooperation of the crank connecting rod 45, the pallet 46 realizes up and down reciprocating motion. During the up and down reciprocating operation of the pallet 46, under the reciprocating impact and dispersion action of the pallet 46, and with the increase of the pusher head 48, the straw gathered in the middle of the conveyor belt 35 can be pushed down and spread. The triangular structure at the bottom of the pallet 46 can push the straw corresponding to the bottom of the pallet 46 downward and spread it to both sides at the same time, realizing the feeding and spreading of the straw. By spreading the straw to both sides, the straw is conveyed in an orderly manner. After the straw is limited in thickness, the conveying channel is formed by the movable plate 41 and the upper surface of the conveyor belt 35, which can evenly disperse the straw. When the straw with limited thickness is fed, it is thrown and screened. During the throwing and separation process, constant-pressure gas is sprayed through the jet nozzle 513 to push the conveyed straw into the throwing channel formed by the guide plate 57 and the flow limiting plate 511, thereby achieving the screening of the straw. Due to the different moisture content of the straw, the straw with higher moisture content is heavier and will drop earlier under the same throwing force, thus achieving the separation of straw with different moisture content during the throwing process. Straw with qualified moisture content can enter the baling host 1 through the throwing channel for baling, while straw with unqualified moisture content cannot pass through the throwing channel, so as to ensure the moisture content of the baled straw and avoid mold and damage.

[0031] In order to cope with different types of straw baling during the straw throwing process, the direction of the air nozzle 513 can be adjusted by loosening the second nut 515 and cooperating with the swing shaft 514 to adapt to the change of the throwing channel. Alternatively, the first nut 54 on the sliding screw 56 can be loosened to allow the sliding screw 56 to slide freely in the sliding hole 52, thereby allowing the guide plate 57 to slide freely on the support frame 51, adjusting the appropriate throwing distance, and cooperating to divert straw with different moisture contents.

[0032] By using the flat-push structure 4 to spread and limit the thickness of the straw, the accumulation of straw can be avoided. With the push of the pallet 46, the material can be distributed to avoid concentrated straw feeding. By distributing the straw, it can be ensured that the straw is fed along the width of the bundled roll, and the straw can be spread better along the width of the bundled roll. After the straw is spread out, it is thrown by the throwing structure 5. After the thickness is limited by the flat pushing structure 4, the throwing process of the throwing structure 5 can be more uniform and achieve better throwing effect. After the straw is thrown and separated, not only can the straw with low moisture content be screened, but also the large solid particles in the straw can be screened to avoid the mixing of large solid particles. At the same time, during the blowing and feeding process, the dry straw enters the baling host 1 in a loose state, so that the loose straw is better rolled and shaped evenly in the baling host 1, avoiding the accumulation and concentrated rolling, and ensuring that the density of the rolled straw is more uniform and the shape is better.
