Description

Technical Field

[0001] The utility model relates to a conveying device, in particular to a linkage conveying device and a harvester. Background Art

[0002] In modern agricultural production, cutting machines are used to harvest crops, for example, cutting machines are used to harvest and transport stem crops. At present, the cutting blades in the cutting machines are usually driven by independent power sources, and in the mechanism for transporting crops, two independent power sources are usually used to drive two conveyor belts to clamp and transport the stem crops. Therefore, the entire cutting machine needs to superimpose multiple power sources to drive the operation of each component, and in the mechanism for transporting crops, the two power sources drive the two conveyor belts separately, which makes it difficult to ensure that the two conveyor belts rotate synchronously, which is easy to affect the transportation effect of stem crops. Therefore, there is an urgent need for a conveying device that can reduce energy consumption and improve the transportation effect. Utility Model Content

[0003] The utility model aims to provide a linkage conveying device and a harvester to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A linkage conveying device comprises: a frame; a conveying unit, which is arranged on the frame, the conveying unit having a rotatable conveying belt, an input shaft transmission-connected to one side of the conveying belt, and an output shaft transmission-connected to the other side of the conveying belt, at least two conveying units are arranged at intervals, and the conveying directions of two adjacent conveying units are the same; a cutting knife, the center of which is connected to a cutting shaft, the number of the cutting knives is at least two, a plurality of the cutting shafts are transmission-connected to a plurality of the output shafts, and two adjacent cutting knives are staggered from each other in the up-down direction; a driving source, which is transmission-connected to the plurality of the input shafts.

[0006] The technical solution has at least the following beneficial effects: when working, the driving source transmits power to the conveying unit through the input shaft, thereby driving the conveyor belt in the conveying unit to rotate. Between two adjacent conveying units, a conveying area is formed between the gaps between the two conveyor belts. When the conveyor belt rotates, power can be transmitted to the output shaft on the other side. Since the output shaft is connected to the cutting shaft on the cutting knife, the cutting knife can be driven to rotate. The stem crops can be cut by two adjacent cutting knives staggered in the upper and lower directions. The top of the stem crops is clamped by the two adjacent conveyor belts. After cutting, the stem crops move along the conveying direction of the conveyor belt in the conveying area to achieve cutting and conveying of the stem crops. In this way, a single driving source provides power for the rotary motion of the conveyor belt and the rotation of the cutting knife, thereby optimizing the overall power composition system, reducing the stacking of motors, and making the operation more energy-efficient. It is also beneficial to ensure that the two adjacent conveyor belts rotate synchronously, thereby achieving stable clamping of the stem crops and improving working stability.

[0007] As a further improvement of the above technical solution, the frame is connected with an angle adjustment seat, the cutting shaft is rotatably connected to the angle adjustment seat, the rotation axis of the cutting shaft extends in the up-down direction, the cutting knife is located at the bottom end of the cutting shaft, and a universal joint is connected between the top end of the cutting shaft and the output shaft. The cutting shaft is rotatably connected to the angle adjustment seat, and the angle adjustment seat can be used to change the inclination angle of the cutting shaft relative to the frame, so that the rotation axis of the cutting knife extends in the up-down direction. At this time, there is an angle between the output shaft and the cutting shaft on the frame, and the universal joint is used to connect the two to each other, so that the power of the output shaft is transmitted to the cutting shaft through the universal joint, driving the cutting knife to rotate synchronously, so that the cutting knife can be conveniently installed on the frame relative to the installation angle required for the cutting knife.

[0008] As a further improvement of the above technical solution, there are two conveying units, which are arranged at intervals, and two conveyor belts form a channel for conveying stem crops, thus forming a cutting and conveying working line.

[0009] As a further improvement of the above technical solution, a connecting sleeve and a transmission gear are rotatably connected on the frame, a first gear is sleeved on the outer side of the connecting sleeve, and second gears are sleeved on the outer sides of the two input shafts, respectively. One of the second gears is meshed with the transmission gear on both sides of the first gear, and the other second gear is meshed with the transmission gear, and the input end of the driving source is connected to the connecting sleeve. The input end of the driving source is connected to the connecting sleeve, so that the connecting sleeve is driven to rotate synchronously. During operation, since the first gear on the outer side of the connecting sleeve is meshed with the second gear and the transmission gear on the outer side of an input shaft, the transmission gear and one input shaft are driven to rotate, and the second gear on the outer side of the other input shaft is meshed with the transmission gear, thereby driving the other input shaft to rotate. At this time, the two input shafts have opposite directions, and one driving source can drive two conveyor belts to rotate synchronously, so as to achieve stable clamping and transportation of stem crops.

[0010] As a further improvement of the above technical solution, an elastic layer is provided on the outer side of the conveyor belt. When the elastic layer on the outer side of the conveyor belt clamps the stem crops, the elastic layer contacts the stem crops, and the elastic deformation of the elastic layer can realize flexible clamping of the stem crops, reduce damage to the stem crops, and greatly improve the stability of clamping the stem crops.

[0011] As a further improvement of the above technical solution, the elastic layer is detachably connected to the conveyor belt. The elastic layer can be removed from the conveyor belt, so that the elastic layer can be easily maintained or replaced, thereby improving the overall use experience.

[0012] As a further improvement of the above technical solution, the elastic layer is a sponge. The sponge, as an elastic layer for clamping and contacting stem crops, can achieve flexible clamping of stem crops, protect stem crops from being damaged, and at the same time ensure a larger clamping area and clamping force, which is conducive to ensuring that the clamped crops do not fall.

[0013] As a further improvement of the above technical solution, the conveying unit includes a side transmission wheel and a middle transmission wheel rotatably arranged on the frame, the two side transmission wheels are respectively connected to the two sides of the conveyor belt along the length direction, the input shaft is connected to one of the side transmission wheels, the output shaft is connected to the other side transmission wheel, and the middle transmission wheel is connected to the middle of the conveyor belt. The two side transmission wheels can stretch and stretch the conveyor belt along its length direction. When working, the input shaft transmits power to one side transmission wheel, and the whole conveyor belt is driven to rotate through the side transmission wheel, thereby driving the side transmission wheel on the other side to rotate. At this time, the output shaft connected to the side transmission wheel is also driven to rotate, thereby outputting power to the cutting shaft, and the middle transmission wheel can be in the middle of the conveyor belt. The middle transmission wheel can tighten the position of one side of the conveyor belt used for clamping and conveying stem crops, so as to achieve that the whole conveyor belt can stably clamp and convey stem crops.

[0014] As a further improvement of the above technical solution, the conveying unit also includes a tensioning wheel rotatably connected to the frame, the tensioning wheel can lift the conveyor belt in a direction away from the other conveying unit, and the tensioning wheel can move on the frame along the length direction of the conveyor belt. By the tensioning wheel moving on the frame along the length direction of the conveyor belt, the overall shape formed by the conveyor belt being stretched outward can be changed, thereby changing the tensioning force of the conveyor belt. After completion, the tensioning wheel can be repositioned on the frame, so that the clamping force of the conveyor belt when clamping and conveying stem crops can be fine-tuned, which is conducive to adapting to the transportation of different fine stem crops and improving the effect of conveying stem crops.

[0025] Reference Figure 1 and Figure 2A linkage conveying device, comprising a frame 100, a conveying unit, a cutting knife 310 and a driving source, wherein the conveying unit is arranged on the frame 100, and the conveying direction of the conveying unit is generally arranged upwardly and obliquely away from the cutting knife 310, so as to lift the cut stem crops to be conveyed to another station, the conveying unit has a rotatable conveying belt 210, an input shaft 220 connected to one side of the conveying belt 210, and an output shaft 230 connected to the other side of the conveying belt 210, and at least two conveying units are arranged at intervals, and the conveying directions of two adjacent conveying units are the same; A cutting shaft 320 is connected to the center of the cutting knife 310, and there are at least two cutting knives 310. The multiple cutting shafts 320 are respectively connected to the multiple output shafts 230, and two adjacent cutting knives 310 are staggered along the up and down directions; the driving source is respectively connected to the multiple input shafts 220. In actual application, two cutting knives 310 staggered along the up and down directions are a cutting group, and two adjacent conveying units are a conveying group. Multiple conveying groups and cutting groups can be arranged side by side, and the numbers correspond to each other. The products cut by each cutting group are collected and conveyed by the corresponding conveying group.

[0026] As can be seen from the above, when working, the driving source transmits power to the conveying unit through the input shaft 220, thereby driving the conveyor belt 210 in the conveying unit to rotate. Between two adjacent conveying units, a conveying area is formed between the gaps between the two conveyor belts 210. When the conveyor belt 210 rotates, the power can be transmitted to the output shaft 230 on the other side. Since the output shaft 230 is connected to the cutting shaft 320 on the cutting knife 310, the cutting knife 310 can be driven to rotate. The two adjacent cutting knives 310 staggered in the upper and lower directions can be used to cut the stems. During crop cutting, the top of the stem crop is clamped by two adjacent conveyor belts 210. After the cutting is completed, the stem crop moves along the conveying direction of the conveyor belt 210 in the conveying area to achieve cutting and conveying of the stem crop. In this way, a single driving source provides power for the rotary motion of the conveyor belt 210 and the rotation of the cutting knife 310, thereby optimizing the overall power component system, reducing the stacking of motors, and making the operation more energy-efficient. It is also beneficial to ensure that the two adjacent conveyor belts 210 rotate synchronously, thereby achieving stable clamping of the stem crops and improving working stability.

[0027] In the above embodiment, the cutting shaft 320 is connected to the output shaft 230 in a transmission manner, and the two may be directly connected to each other, or a transmission structure may be added to realize the transmission of power from the output shaft 230 to the cutting shaft 320. Since the conveying angle of the conveying unit on the frame 100 needs to be configured in conjunction with the next workstation, and the cutting knife 310 is preferably configured to have a rotation axis extending in a vertical direction in order to better cut stem crops, in this embodiment, an angle adjustment seat 110 is connected to the frame 100, and the cutting shaft 320 is rotatably connected to the angle adjustment seat 110, and the rotation axis of the cutting shaft 320 extends in the up and down directions. The cutting knife 310 is located at the bottom end of the cutting shaft 320, and a universal joint 330 is connected between the top end of the cutting shaft 320 and the output shaft 230. The cutting shaft 320 is rotatably connected to the angle adjustment seat 110. The angle adjustment seat 110 can be used to change the inclination angle of the cutting shaft 320 fixed to the frame 100, so that the rotation axis of the cutting knife 310 extends in the up-down direction. At this time, there is an angle between the output shaft 230 on the frame 100 and the cutting shaft 320. The universal joint 330 is used to connect the two to each other, so that the power of the output shaft 230 is transmitted to the cutting shaft 320 through the universal joint 330, driving the cutting knife 310 to rotate synchronously, so that the cutting knife 310 can be conveniently installed relative to the frame 100 according to the installation angle requirements of the cutting knife 310. In practical applications, the angle adjustment seat 110 can be a structurally fixed accessory, and the installation requirements of the cutting knife 310 are met by forming an inclined surface on its surface, or it can be an accessory that can change the rotation angle and position, and the inclination angle can be flexibly changed to meet the installation requirements of the cutting knife 310.

[0028] In some embodiments, there are two conveying units, and in this case, there can also be two cutting knives 310, and the gap between the two conveying units corresponds to the position where the two cutting knives 310 are offset from each other. The two conveying units are arranged at intervals, and the two conveyor belts 210 form a channel for conveying stem crops, thus forming a cutting and conveying working line.

[0029] The driving source is respectively connected to the two input shafts 220 by transmission, and the driving source can be respectively connected to the two input shafts 220 by transmission through belts. In this embodiment, a connecting sleeve 120 and a transmission gear 130 are rotatably connected to the frame 100, and a first gear 121 is sleeved on the outer side of the connecting sleeve 120, and second gears 221 are respectively sleeved on the outer sides of the two input shafts 220. One of the second gears 221 is respectively meshed with the transmission gear 130 on both sides of the first gear 121, and the other second gear 221 is meshed with the transmission gear 130. The input end of the driving source is connected to the connecting sleeve 120. The driving source can be a reduction motor, and the rotating rod of the reduction motor is the input end of the driving source. The input end of the driving source is connected to the connecting sleeve 120, so that the connecting sleeve 120 is driven to rotate synchronously. During operation, the first gear 121 on the outside of the connecting sleeve 120 is engaged with the second gear 221 and the transmission gear 130 on the outside of an input shaft 220, so that the transmission gear 130 and an input shaft 220 are driven to rotate, and the second gear 221 on the outside of the other input shaft 220 is engaged with the transmission gear 130, thereby driving the other input shaft 220 to rotate. At this time, the two input shafts 220 have opposite directions, and one driving source can drive the two conveyor belts 210 to rotate synchronously, thereby realizing stable clamping and transportation of stem crops.

[0030] In order to better utilize the two conveyor belts 210 to clamp the stem crops, in this embodiment, an elastic layer is provided on the outer side of the conveyor belt 210. When the elastic layer on the outer side of the conveyor belt 210 clamps the stem crops, the elastic layer contacts the stem crops, and the elastic deformation of the elastic layer can realize flexible clamping of the stem crops, reduce damage to the stem crops, and greatly improve the stability of clamping the stem crops.

[0031] Furthermore, the elastic layer is detachably connected to the conveyor belt 210, for example, the elastic layer can be directly bonded to the outside of the conveyor belt 210, or the elastic layer can be connected to the outside of the conveyor belt 210 via Velcro. The elastic layer can be removed from the conveyor belt 210, so that the elastic layer can be easily maintained or replaced, thereby improving the overall user experience.

[0032] The elastic layer can be made of rubber, cloth or other materials, and in this embodiment, the elastic layer is sponge. The sponge, as the elastic layer for clamping the stem crops, can achieve flexible clamping of the stem crops, protect the stem crops from being damaged, and at the same time ensure a larger clamping area and clamping force, which is conducive to ensuring that the clamped crops do not fall.

[0033] As a specific structural embodiment of the conveying unit, the conveying unit includes a side transmission wheel 240 and a middle transmission wheel 250 rotatably arranged on the frame 100, the two side transmission wheels 240 are respectively connected to the two sides of the conveyor belt 210 along the length direction, the input shaft 220 is connected to one of the side transmission wheels 240, the output shaft 230 is connected to the other side transmission wheel 240, and the middle transmission wheel 250 is connected to the middle of the conveyor belt 210. In actual application, the frame 100 is provided with bearing seats at both ends of the conveyor belt 210 in the length direction and at the middle of the conveyor belt 210 for mounting the two side transmission wheels 240 and the middle transmission wheel 250. The middle drive wheel 250 and the two side drive wheels 240 can be directly connected to the input shaft 220 and the output shaft 230 in two bearing seats through bearings, and then the two side drive wheels 240 can be connected to the input shaft 220 and the output shaft 230 respectively, so that the input shaft 220 and one side drive wheel 240 can rotate synchronously, and the output shaft 230 and the other drive wheel can rotate synchronously. In addition, in order to better transfer the stem crops in the conveying area, the middle drive wheel 250 close to the conveying area and the two side drive wheels 240 are located on the same straight line. At this time, the surface of the conveyor belt 210 close to the conveying area is a straight conveying surface, so that the conveying area is formed by two straight conveying surfaces.

[0034] In this conveying unit, the two side drive wheels 240 can stretch and tighten the conveyor belt 210 along its length direction. During operation, the input shaft 220 transmits power to one side drive wheel 240, and the entire conveyor belt 210 is driven to rotate through the side drive wheel 240, thereby driving the side drive wheel 240 on the other side to rotate. At this time, the output shaft 230 connected to the side drive wheel 240 is also driven to rotate, thereby outputting power to the cutting shaft 320, and the middle drive wheel 250 can be in the middle of the conveyor belt 210. The middle drive wheel 250 can tighten the side position of the conveyor belt 210 used for clamping and conveying stem crops, so as to achieve that the entire conveyor belt 210 can stably clamp and convey stem crops.

[0035] Furthermore, the conveying unit further comprises a tension wheel 260 rotatably connected to the frame 100, the tension wheel 260 can lift the conveyor belt 210 in a direction away from another conveying unit, and the tension wheel 260 can move on the frame 100 along the length direction of the conveyor belt 210. By the tension wheel 260 moving on the frame 100 along the length direction of the conveyor belt 210, the overall shape formed by the conveyor belt 210 being stretched outward can be changed, thereby changing the tension of the conveyor belt 210. After completion, the tension wheel 260 can be repositioned on the frame 100, so that the clamping force of the conveyor belt 210 when clamping and conveying stem crops can be finely adjusted, which is conducive to adapting to the transportation of different fine stem crops and improving the effect of conveying stem crops. In actual applications, for the installation of the tensioning wheel 260 on the frame 100, a bearing seat can also be set on the frame 100, and the tensioning wheel 260 can be connected to the bearing seat through a bearing, and the bearing seat can be movable on the frame 100 along the length direction of the conveyor belt 210, so as to adjust the position of the tensioning wheel 260. After the adjustment is completed, screws, bolts and other connecting parts are inserted into the bearing seat, and the bearing seat is pressed and fixed on the frame 100 to realize the positioning of the tensioning wheel 260.

[0037] In this harvester, the power component structure is optimized to reduce the stacking of motors, making the operation more energy-saving and environmentally friendly. It is also safer and more reliable through pure mechanical linkage, achieving stable clamping of stem crops and improving working stability.
