Description

Technical Field

[0001] This utility model provides a bidirectional centralized conveying and feeding device for hemp harvesting platform, belonging to the field of agricultural equipment, and is mainly used for harvesting hemp and other stalk crops. Background Technology

[0002] Apocynum venetum is a fiber plant with salt and alkali tolerance and drought resistance, making it suitable for ecological restoration and possessing high economic value. However, the lack of standardized cultivation techniques and constraints imposed by water resources in arid regions and low harvesting efficiency pose significant challenges to the industrialization of Apocynum venetum, severely hindering its sustainable development.

[0003] Apocynum venetum grows mainly in desert and saline-alkali areas, and is primarily harvested manually, which is labor-intensive and costly. Existing harvesting machinery mainly consists of modified grain harvesters and small mowers, with some producing areas using semi-automatic handheld electric brush cutters. These methods are inefficient and lack adaptability. Furthermore, current Apocynum venetum harvesting techniques generally suffer from inconsistent stubble heights during manual harvesting, affecting the germination rate the following year, while mechanical harvesting results in poor quality, leading to difficulties in subsequent processing.

[0004] Looking at the current state of the agricultural equipment industry, there is an urgent need for a bidirectional centralized conveying and feeding device for hemp harvesting tables that has high harvesting efficiency, good stubble uniformity, and functions such as lifting, pulling, and automatic feeding of hemp. Utility Model Content

[0005] The purpose of this invention is to provide a bidirectional centralized conveying and stalk feeding device for hemp harvesting platform that can overcome the problems existing in the current agricultural equipment industry, and has not only high harvesting efficiency and good stubble uniformity, but also a high degree of automation.

[0006] The technical solution includes a header frame, cutting components, a bidirectional conveying device, a baling device, and a baling device. The header frame comprises a frame body, guard plates, balers, and side output guide plates. The frame body has a planar frame structure. A plane perpendicular to the long frame and perpendicular to the frame plane is defined as the plane of symmetry of the header frame. After one long frame of the planar frame is broken in the middle, U-shaped guard plates are installed on the outer sides of both planar frame sections. Balers extend from the two short frames on one side of the frame plane in a direction perpendicular to the frame plane. Side output guide plates are installed on the frame plane of the frame body away from the balers. The header frame is connected to the tractor via the frame plane of the frame body away from the balers. The long frame of the cutter head, after the plane frame of the cutter head is disconnected, is located at the top. The cutting assembly includes fixed blades, moving blades, blade shanks, connecting rods, rocker arms, vibration damping blocks, cutting drives, balancing eccentric blocks, and connecting rods. Multiple fixed blades are mounted on the frame plane extending from the side of the cutter head that has the harvester, located on the long frame near the ground. The plane of the fixed blades is perpendicular to the frame plane of the cutter head and parallel to the long frame frame. The blade shank with multiple moving blades slides on the side of the frame plane near the center of the fixed blades. The cutting plane of the moving blades is in contact with the cutting plane of the fixed blades, and the length direction of the blade shank is parallel to the frame plane of the cutter head. A connecting rod is mounted on the side of the moving blade away from the fixed blade, and the connecting rod is close to the blade. One end of the rod is hinged to a rocker arm, and the other end of the rocker arm is hinged to the frame plane of the cutting table. The cutting drive is installed on the frame plane of the cutting table. A balancing eccentric block is mounted on the output shaft of the cutting drive. One end of the connecting rod is fitted onto the eccentric shaft of the balancing eccentric block, and the other end is hinged to the middle of the rocker arm. The bidirectional conveying device includes a drive roller, a conveying shaft, a conveying drive, a drive shaft, a chain drive, a gear drive, a driven roller, a toothed conveyor belt, and an auxiliary feed wheel. The outer diameter of the drive roller is smaller than the inner width of the U-shaped groove of the cutting table's guard plate. The two conveying shafts, each equipped with three drive rollers, are supported at both ends on the middle of the two long side frames of the frame plane of the cutting table, and the two conveying shafts are symmetrically arranged relative to the cutting table. The conveying drive is installed on the frame plane. On the frame plane, the conveyor drive output shaft is connected to one end of the drive shaft, and the other end of the drive shaft is supported on the frame plane of the platform. The middle part of the drive shaft is connected to one conveyor shaft through chain drive. The two conveyor shafts have their ends extending through the long side frame of the platform near the ground and connected to another chain drive through gear drive. Three driven rollers with the same outer diameter as the drive roller are supported on the frame plane of the platform near the short side frame. The axes of the three driven rollers are coaxial and are respectively in the same plane as the three drive rollers installed on the conveyor shaft. Another three driven rollers are supported on the frame plane of the platform near another short side frame. The axes of the three driven rollers are coaxial and are respectively in the same plane as the three drive rollers installed on the conveyor shaft.The annular toothed conveyor belt has several teeth along its annular length on its outer surface. Three toothed conveyor belts are respectively hung on three driving rollers and three driven rollers at the same end of the frame plane of the platform. Another three toothed conveyor belts are respectively hung on three driving rollers and three driven rollers at the other end of the frame plane of the platform. The tight section of all toothed conveyor belts faces the direction of machine movement. The teeth of all toothed conveyor belts extend beyond the U-shaped groove of the cutter frame after passing through the guard plate. One auxiliary feeding wheel is installed at the extended end of the drive shaft after passing through the long side frame of the platform. Another auxiliary feeding wheel is installed above the long side frame of the platform and connected to the conveyor shaft away from the drive shaft via another chain drive. The rice-feeding device includes a rice-picking frame, a dividing plate, a rice-picking star wheel, a rice-pressing spring I, and a rice-pressing spring II. The rice-picking frame has a planar frame structure, the dividing plate is triangular in shape with one acute angle, and the dividing plate... A dividing plate is installed on one side of the reeling frame, with its surface perpendicular to the frame plane. A reeling star wheel is mounted on the side of the dividing plate closest to the reeling frame, located away from the acute angle of the dividing plate, and its axis is perpendicular to the dividing plate surface. A pressing rod I is J-shaped, with its J-shaped head mounted on the end of one reeling star wheel shaft furthest from the dividing plate. A pressing rod II is S-shaped, with its end furthest from the S-shape mounted on the other reeling star wheel shaft. Two separate feeding devices are symmetrically installed on the cutter frame near the star wheel, one at each end of the dividing plate. The cutting components are mounted on the fixed blades of the cutter frame. Both feeding devices have their pressing rods (II) mounted on the cutter frame in the middle of the frame. All dividing plate surfaces of the two feeding devices are on the same plane, with the acute angles of the dividing plates pointing towards the machine's forward direction. All star wheels and the toothed conveyor belt of the bidirectional conveyor are at the same height.

[0007] Compared with the existing technology, this invention, because the harvesting platform is attached to the tractor, can automatically control the ground clearance and longitudinal tilt angle of the harvesting platform according to different crops such as Apocynum venetum and terrain characteristics. It can also automatically adjust the lateral tilt angle of the harvesting platform, thereby improving the adaptability of the implement to the environment and terrain. Because the harvesting platform frame has crop lifters on both sides, a crop feeding device in the middle, and a toothed conveyor belt in the bidirectional conveyor system, the crops such as Apocynum venetum are effectively lifted by the toothed conveyor belt and the crop lifters. Together with the feeding device, the rice stalks are fed in a concentrated bidirectional manner towards the center of the harvesting platform, thus reducing blockages and improving feeding efficiency. Because the feeding device includes a dividing plate, a star wheel, and pressing rods I and II, and the bidirectional conveyor uses a toothed conveyor belt, the cut stalks of crops such as Apocynum venetum are evenly compressed between the toothed conveyor belt and the pressing rods I and II under the combined action of the toothed conveyor belt, the dividing plate, the star wheel, and the pressing rods I and II. The bidirectional centralized conveying towards the center of the header, coupled with the actuating action of the auxiliary feeding wheels mounted on the header, prevents crops such as Apocynum venetum from deviating from the header due to the loose upper branches and leaves. This allows for sorting and separate feeding, further improving feeding efficiency. Because a side output guide plate is located at the rear of the header, crops such as Apocynum venetum transported to the center of the header are guided by the side output guide plate and then conveyed to one side of the header for baling under the reverse conveying action of the loose section of the toothed conveyor belt. This means that both the tight and loose sections of the toothed conveyor belt can be used for conveying, thereby improving equipment utilization and operational efficiency. The continuously variable speed drive of the toothed conveyor belt improves adaptability to the height of crops such as Apocynum venetum, thus preventing congestion and improving conveying efficiency. The harvesting table uses a reciprocating cutting device with vibration damping function, effectively reducing impact and vibration. Furthermore, the continuously variable speed cutting drive adapts to different operating conditions and harvesting requirements of different crops, extending the life of the cutting components.

[0017] exist Figures 1-8In the illustrated embodiment: the cutter frame 1 has a planar frame structure. The plane perpendicular to the long frame and perpendicular to the frame plane of the cutter frame 1 is defined as the plane of symmetry of the cutter frame 1. After one long frame of the planar frame of the cutter frame 11 is broken in the middle, both sections of the planar frame are equipped with U-shaped protective plates 12 to prevent the stalks and branches of crops such as Apocynum venetum from getting tangled. Two short frames on one side of the frame plane of the cutter frame 11 extend with stalk straighteners 13 in a direction perpendicular to the frame plane of the cutter frame 11 to straighten and guide the stalks of crops such as Apocynum venetum to be in an upright and stable state, which is convenient for subsequent cutting. The frame plane of the cutter frame 11 away from the stalk straighteners 13 is equipped with a side output guide plate 14 to guide the stalks of crops such as Apocynum venetum that are fed in and pass through the middle of the planar frame of the cutter frame 11 to be conveyed to one side, which is convenient for subsequent baling operations. The header frame 1 is attached to the front of the tractor via the frame plane of the header body 11 on the side away from the loader 13, with the long side of the cut frame of the header body 11 located at the top. The height of the header frame 1 relative to the tractor is adjustable, and it can swing around the longitudinal axis of the tractor. The multiple fixed blades 21 of the cutting assembly 2 are installed on the frame plane of the header body 11 on the side where the loader 13 is located, and are located at the long side of the side closer to the ground. The plane of the multiple fixed blades 21 is perpendicular to the frame plane of the header body 11 and parallel to the long side of the frame plane of the header body 11. The blade shank 23 with multiple movable blades 22 is slidably mounted on the side of the multiple fixed blades 21 near the center of the frame plane of the header body 11. The cutting plane of the multiple movable blades 22 is in contact with the cutting plane of the multiple fixed blades 21, and the length direction of the blade shank 23 is parallel to the frame plane of the header body 11, so as to cut the straw of crops such as Apocynum venetum fed to the movable blades 22 and fixed blades 21. A connecting rod 24 is mounted on the side plate away from the fixed blade 21 of the moving blade 22. One end of the connecting rod 24 near the end of the blade holder 23 is hinged to a rocker arm 25, and the other end of the rocker arm 25 is hinged to the frame plane of the frame body 11 of the cutting table 1. A stepless speed-regulating cutting drive 26 is mounted on the frame plane of the frame body 11. A balancing eccentric block 27 is mounted on the output shaft of the cutting drive 26 to balance the impact and vibration caused by the reciprocating movement of the moving blade 22 and the blade holder 23. One end of the connecting rod 28 is fitted on the eccentric shaft of the balancing eccentric block 27, and the other end is hinged to the middle of the rocker arm 25. Therefore, the cutting drive 26 can drive the rocker arm 25 to swing back and forth through the balancing eccentric block 27 and the connecting rod 28, thereby driving the blade holder 23 and the moving blade 22 to move back and forth.The outer diameter of the drive roller 31 of the bidirectional conveying device 3 is smaller than the inner width of the U-shaped groove of the guard plate 12 of the cutting table 1. The two conveying shafts 32, which are equipped with three drive rollers 31, are supported at both ends on the middle of the two long side frames of the frame plane of the frame body 11 of the cutting table 1, and the two conveying shafts 32 are arranged symmetrically with respect to the cutting table 1. The continuously variable speed conveying drive 33 is installed on the frame plane of the frame body 11. The output shaft of the conveying drive 33 is connected to one end of the drive shaft 34, and the other end of the drive shaft 34 is supported on the frame plane of the frame body 11. The middle part of the drive shaft 34 is connected to one conveying shaft 32 through the chain drive 35. The protruding ends of the two conveying shafts 32, which are facing the ground, are connected to another chain drive 35 through the gear drive 36 after passing through the long side frame of the frame body 11 near the ground, so as to ensure that the two conveying shafts rotate in opposite directions. Three driven rollers 37, with an outer diameter equal to that of the driving roller 31, are supported on the frame plane of the platform body 11 near the short side. The axes of the three driven rollers 37 are coaxial and are respectively located in the same plane as the three driving rollers 31 mounted on the conveyor shaft 32. Another three driven rollers 37 are supported on the frame plane of the platform body 11 near another short side. The axes of the three driven rollers 37 are coaxial and are respectively located in the same plane as the three driving rollers 31 mounted on the conveyor shaft 32. The annular toothed conveyor belt 38 has several teeth on its annular outer surface along its annular length. Three toothed conveyor belts 38 are respectively hung on three driving rollers 31 and three driven rollers 37 located at the same end of the frame plane of the frame body 11. Another three toothed conveyor belts 38 are respectively hung on three driving rollers 31 and three driven rollers 37 located at the other end of the frame plane of the frame body 11. The tight section of all toothed conveyor belts 38 faces the forward direction of the machine. After passing through the guard plate 12 of the cutter frame 1, the teeth of all toothed conveyor belts 38 extend out of the U-shaped groove of the guard plate 12, so as to convey the cut crop straw such as Apocynum venetum to the middle of the cutter frame 1 in both directions. One auxiliary feeding wheel 39 is installed at the extended end of the drive shaft 34 after passing through the long side frame of the frame body 11. Another auxiliary feeding wheel 39 is installed above the long side frame of the frame body 11 and connected to the conveying shaft 32 away from the conveying drive 33 via another chain drive 35. This enables combing and feeding of the rice, effectively preventing the rice stalks of crops such as Apocynum venetum from deviating from the header due to the loose upper branches and leaves. The rice feeding device 4 has a rice-picking frame 41 with a planar frame structure. The rice-dividing plate 42 is triangular with one acute angle. The rice-dividing plate 42 is installed on one side of the rice-picking frame 41, and the surface of the rice-dividing plate 42 is perpendicular to the frame plane of the rice-picking frame 41. A rice-picking star wheel 43 is installed on the side of the rice-dividing plate 42 closest to the rice-picking frame 41. The rice-picking star wheel 43 is located away from the acute angle of the rice-dividing plate 42, and the axis of the rice-picking star wheel 43 is perpendicular to the surface of the rice-dividing plate 42.The pressing rod I 44 is J-shaped, and the J-shaped head of the pressing rod I 44 is installed on the end of the shaft of one reeling star wheel 43 away from the dividing plate 42. The pressing rod II 45 is S-shaped, and the end of the pressing rod II 45 away from the S-shape is installed on the end of the shaft of another reeling star wheel 43 away from the dividing plate 42. The two reeling feeding devices 4 are symmetrically installed on the frame body 11 of the cutter frame 1 near the fixed blade 21 of the cutting component 2 through the reeling frame 41. The reeling frames 41 of the two reeling feeding devices 4 with pressing rod II 45 are both located in the middle of the frame body 11. All the dividing plates 42 of the two reeling feeding devices 4 are located in the same plane, and the acute angles of the dividing plates 42 are all facing the forward direction of the machine. All the reeling star wheels 43 and the toothed conveyor belt 38 of the bidirectional conveyor 3 are at the same height. During the harvesting process, each grain-pulling star wheel 43 is rotated by the grain-pulling tooth conveyor belt 38, so that the cut crop stalks such as Apocynum venetum can be pulled to the grain-pulling tooth conveyor belt 38, and then evenly pressed between the grain-pressing spring rod I 44 and the grain-pressing spring rod II 45 under the action of the pressing spring rod I 44 and the pressing spring rod II 45, and then fed into the middle of the header frame 1 in both directions.

[0018] Its working principle is as follows: The harvesting platform is attached to the tractor. Based on the characteristics of different crops such as hemp and the terrain, the ground clearance and longitudinal tilt angle of the harvesting platform are adjusted, as well as the cutting and conveying drive speeds. When encountering laterally sloping terrain, the implement can automatically adjust the lateral tilt angle. After the implement moves with the tractor to the plot to be harvested, the cutting drive of the cutting assembly is activated. Through the balancing eccentric block, connecting rod, and rocker arm, the cutter bar reciprocates, which in turn drives the moving cutter to reciprocate. The conveying drive of the bidirectional conveying device is activated, driving one conveyor shaft and drive roller to rotate via the drive shaft and chain drive. This, in turn, drives another conveyor shaft and drive roller to rotate via gear transmission and another chain drive, thus driving the toothed conveyor belts. Simultaneously, the drive shaft also drives one auxiliary feed wheel to rotate, and another auxiliary feed wheel is driven by the conveyor shaft through another chain drive. Additionally, the toothed conveyor belts also drive the grain feeding device's grain feeding star wheel to rotate, and the harvesting operation begins.

[0019] As the machine moves forward, the straw of crops such as Apocynum venetum, supported by the straw supports on both sides of the header, enters the cutting edge of the moving and stationary blades of the cutting assembly and is quickly cut by the reciprocating moving blade. The inclusion of a balancing eccentric block effectively reduces impact and vibration, extending the lifespan of the cutting assembly.

[0020] After being cut, the stalks of crops such as Apocynum venetum are guided by the dividing plate of the feeding device and moved towards the toothed conveyor belts by the action of the star wheel. Then, under the action of the toothed conveyor belts of the bidirectional conveyor device and the elastic action of the pressing rods I and II, they are evenly compressed between the tight section of the toothed conveyor belt and the pressing rods I and II, and conveyed bidirectionally towards the center of the header. The auxiliary feeding wheel installed on the header gathers the loose branches and leaves at the top of the stalks of crops such as Apocynum venetum together to prevent the stalks from deviating from the header. Therefore, the combing, dividing, feeding, and bidirectional centralized conveying are smooth and the operation is highly reliable.
