Description

Technical Field

[0001] The present invention relates to the technical field of peanut harvesting equipment, in particular to a peanut harvester. Background Art

[0002] Peanut vines are important livestock feed with high economic value. Peanut harvesters are equipped with vine boxes to collect the vines harvested by the peanut machines.

[0003] like Figure 15 As shown, the arrows in the figure represent the flow direction and flow trajectory of the material. The peanut machine cleaning system on the domestic market mainly relies on the second cleaning fan 32 to supply air, and cooperates with the third seedling collecting fan 33 to clean the screen surface and the peanuts at the tail of the second sieve 34. Among them, in addition to assisting in cleaning, the third seedling collecting fan 33 also has another function of collecting a large amount of material from the chopper 35 by suction and sucking it into the seedling box. The third seedling collecting fan 33 takes into account both the auxiliary cleaning and the conveying of seedlings. Because the seedling flow and the cleaning air path overlap during operation, they affect each other and the speed of the fan cannot be adjusted according to the working conditions. In addition, because the third seedling collecting fan 33 needs to be in direct contact with a large amount of material during operation, the third seedling collecting fan 33 suffers from severe wear and reduces its service life. Summary of the Invention

[0006] The beneficial effect of the technical solution of the present invention is to provide a peanut harvester with a cleaning system that specifically integrates a collecting fan with a cleaning fan to complete peanut cleaning. This system eliminates the influence of other factors such as material flow on the cleaning system, allowing the cleaning system to be individually adjusted for different operating conditions during peanut harvesting, resulting in greater targeted performance. It also reduces the amount of material passing through the collecting fan, reducing the fan speed to half its original speed under the same wind field, significantly extending the collecting fan's service life.

[0007] Furthermore, the first conveying channel and the second conveying channel are arranged side by side in the left-right direction.

[0008] The benefits of this enhanced technical solution include a compact structure, providing a peanut harvester with a cleaning system that uses a collecting fan specifically for cleaning peanuts.

[0018] The beneficial effects of adopting the above further technical solution are: the augers are used to transport the materials. The shredders shred the materials, and after the materials are shredded, they are sucked to the blades by the suction capacity of the throwing mechanism and thrown out by the centrifugal action of the blades of the throwing mechanism.

[0019] Furthermore, the shredding device includes: a cutter disc, multiple movable knives and multiple fixed knives. The cutter disc is coaxially arranged with the agitator device and the throwing mechanism. The multiple movable knives are installed on the cutter disc at intervals.

[0050] The beneficial effect of the technical solution of the present invention is to provide a peanut harvester with a cleaning system that specifically integrates a collecting fan with a cleaning fan to complete peanut cleaning. This system eliminates the influence of other factors such as material flow on the cleaning system, allowing the cleaning system to be individually adjusted for different operating conditions during peanut harvesting, resulting in greater targeted performance. It also reduces the amount of material passing through the collecting fan, reducing the fan speed to half its original speed under the same wind field, significantly extending the collecting fan's service life.

[0054] like Figures 1 to 14 As shown, further, the first conveying channel 26 and the second conveying channel 28 are arranged side by side in the left-right direction.

[0055] The benefits of this enhanced technical solution include a compact structure, providing a peanut harvester with a cleaning system that uses a collecting fan specifically for cleaning peanuts. This system eliminates the impact of other factors, such as material flow, on the cleaning system, allowing for individual adjustments to different operating conditions during peanut harvesting, resulting in greater targeted performance.

[0056] like Figures 1 to 14 As shown, further, the vine conveying and chopping device 27 includes an agitator device, a chopping device and a throwing mechanism which are coaxially arranged in sequence in the left and right directions, the agitator device is located on the inner side of the chopping device, the throwing mechanism is located on the outer side of the chopping device, the agitator device is connected to the grass discharge port of the de-separation unit 24, and the throwing mechanism is connected to the second conveying channel 28; the agitator device is used to convey the vines from the grass discharge port of the de-separation unit to the chopping device, and the throwing mechanism conveys the chopped vines to the vine storage device through the second conveying channel 28.

[0057] The beneficial effects of adopting this further technical solution are as follows: the auger device conveys a large amount of peanut vines from the drum to the throwing mechanism, where the vines are chopped by the chopping device. Finally, after being thrown by the throwing mechanism, the peanut vines are thrown through a second conveying channel to the vine storage device. The throwing mechanism replaces the gathering function of the seedling collecting fan, improving the durability of the entire machine and reducing the failure rate of the seedling collecting mechanism. By directing the material out of the drum for throwing and collecting, the first seedling collecting fan is only involved in cleaning, reducing wear on the first seedling collecting fan and extending its service life.

[0058] The housing 3, the second throwing drum 10, and the drum 18 are mounted on the frame 19. A chopping device for chopping the vines, a throwing mechanism for throwing the vines, and an auger device for conveying the vines are rotatably mounted in the housing 3. The auger device is connected to the output end of the drum 18, the chopping device is connected to the auger device, and the throwing mechanism is connected to the chopping device. The two ends of the second throwing drum 10 are connected to the vine box 20 and the throwing mechanism, respectively. The drum 18 can be tilted.

[0059] The auger, chopping, and throwing mechanisms are all mounted on the first rotating shaft, with the chopping mechanism located between them. An intermediate shaft 36 is mounted on the frame and is in transmission connection with the first rotating shaft. The auger, chopping, and throwing mechanisms are all mounted on the first rotating shaft, facilitating their synchronous rotation, simplifying the transmission structure and improving operational efficiency. The chopping mechanism is located between the auger and throwing mechanisms, facilitating the sequential conveying, chopping, and throwing processes. The intermediate shaft 36 is in transmission connection with the first rotating shaft, allowing it to drive the rotation of the first rotating shaft, thereby providing power for the auger, chopping, and throwing mechanisms.

[0060] Wherein, the first rotating shaft can be arranged horizontally.

[0061] A lining plate 13 may be mounted on the inner wall of the housing 3. The lining plate prevents the housing from being worn through and improves wear resistance. The lining plate may be made of metal.

[0062] The shell 3 is provided with an input port for communicating with the output end of the drum 18. The shell 3 is connected to the second throwing cylinder 10 through a joint 9. The second throwing cylinder 10 is located above the shell 3. The provision of the input port facilitates the material at the output end of the drum to directly enter the auger device through the input port. The shell is connected to the second throwing cylinder through a joint, which facilitates the adaptive connection between the second throwing cylinder and the shell, and facilitates the installation and maintenance of the second throwing cylinder. The second throwing cylinder is located above the shell, which facilitates the second throwing cylinder to transport materials to the vine box and is convenient for adapting to the height of the vine box. Among them, the second throwing cylinder 10 can be an L-shaped cylinder.

[0063] A tensioning pulley bracket can be mounted on the housing 3. A threaded rod and a guide rod are rotatably mounted on the tensioning pulley bracket. A nut is threadedly connected to the threaded rod, which in turn is connected to a mounting plate. The mounting plate is slidably mounted on the guide rod. A tensioning pulley 8 is rotatably mounted on the mounting plate. The tensioning pulley 8 abuts the belt between the second pulley 15 and the first pulley 7. The first rotating shaft is rotatably mounted in the housing via a bearing seat. The tensioning pulley is adjustably mounted on the housing, allowing the user to adjust the belt tension as needed and simplifying the tensioning pulley's position adjustment. The first rotating shaft is rotatably mounted in the housing via a bearing seat. This facilitates installation and maintenance of the first rotating shaft, reduces friction between the first rotating shaft and the housing, and extends its service life.

[0064] Among them, a threaded area can be provided in the middle of the threaded rod, and a nut adapted to the threaded rod can be installed on the mounting plate. The nut is connected to the threaded rod through threads. Rotating the threaded rod allows the mounting plate to slide along the guide rod to achieve position adjustment of the tensioning wheel.

[0065] A reinforcement bracket 4 and a cover plate 6 can be mounted on the housing 3. The housing 3 is connected to the frame 19 via the reinforcement bracket 4. The cover plate 6 is provided with an observation window 5, which is secured with a baffle. The reinforcement bracket facilitates a stable connection between the housing and the frame, increasing load resistance. The observation window facilitates observation of the interior of the housing.

[0066] The cross section of the reinforcing bracket 4 may be L-shaped. The baffle may be mounted at the position of the observation window 5 by means of bolts.

[0067] like Figures 1 to 14 As shown, further, the agitator device is located on the inner side of the lower part of the first conveying channel 26, and the agitator device is installed between the left wall 37 and the right wall 38 of the first conveying channel 26; the shredding device and the throwing mechanism are located outside the first conveying channel 26.

[0068] The beneficial effects of adopting the above further technical solution are: compact structure and reduced space occupancy.

[0069] like Figures 1 to 14 As shown, further, the auger device includes an auger shell 29 and an auger 2 arranged in the auger shell 29, the auger shell 29 includes an arcuate shell provided with an axial feed port and a grass guide plate 30 fixed between the feed port of the arcuate shell and the grass discharge port of the de-separating unit 24, the feed port of the arcuate shell is connected to the grass discharge port of the de-separating unit 24, the arcuate shell is used to separate the auger device and the first conveying channel 26, and the grass guide plate 30 is used to separate the auger device and the cleaning unit 25.

[0070] The beneficial effect of adopting this further technical solution is that the auger conveys a large amount of peanut vines from the drum to the throwing mechanism. The auger device is separated from the first conveying channel by a curved shell, and the auger device is separated from the cleaning unit by a grass guide plate. In the first conveying channel, the curved shell also serves as an air guide, ensuring smooth air flow.

[0071] The auger 2 can be a spiral blade mounted on the first rotating shaft. A reinforcing rib can be installed on one side of the spiral blade, connected to the first rotating shaft. The reinforcing rib can be a triangular structure. An auger 2 is added to the end of the drum 18. The auger 2 conveys a large amount of peanut vines from the drum 18 to the right side, shredding the vines in the process. Finally, the peanut vines are thrown by the throwing mechanism and then thrown by the second throwing cylinder 10 into the vine box.

[0072] like Figures 1 to 14 As shown, further, the throwing mechanism includes: an impeller and a plurality of blades 14 arranged coaxially with the agitator device and the chopping device, and the plurality of blades 14 are installed on the impeller at intervals.

[0073] The beneficial effect of adopting the above further technical solution is that the particles are thrown out by the centrifugal action of the blades.

[0074] The blades 14 may be multiple and may be trapezoidal plates, and may be arranged at equal intervals along the circumference of the first rotating shaft. A disc may be provided on the side of the blade 14 away from the auger 2, the disc being mounted on the first rotating shaft for blocking material.

[0075] Furthermore, the shredding device is located between the first conveying channel and the throwing mechanism.

[0076] The beneficial effects of adopting the above further technical solution are: the augers are used to transport the materials. The shredders shred the materials, and after the materials are shredded, they are sucked to the blades by the suction capacity of the throwing mechanism and thrown out by the centrifugal action of the blades of the throwing mechanism.

[0077] like Figures 1 to 14 As shown, further, the shredding device includes: a cutter disc, a plurality of movable knives 11 and a plurality of fixed knives 12, the cutter disc is coaxially arranged with the agitator device and the throwing mechanism, the plurality of movable knives 11 are installed on the cutter disc at intervals, a shell 3 is installed on the vine conveying and shredding device, and the plurality of fixed knives 12 are installed in the shell 3 at intervals.

[0078] The beneficial effect of adopting the above further technical solution is that when the material falls from the drum into the auger, it is transported by the auger to the moving knife and the fixed knife for chopping, which makes it easier for the chopped device to chopped the vines.

[0079] The cutter disc can be mounted on the first rotating shaft, with multiple movable blades 11 installed at intervals on the cutter disc, and multiple fixed blades 12 installed at intervals in the housing 3. When the material falls from the drum into the auger, it is transported by the auger to the movable and fixed blades for shredding, facilitating the shredding device to shred the vines.

[0080] As an alternative to the cutter disc, a movable cutter can be mounted on the first rotating shaft via a cutter holder, and the movable cutter is located between two adjacent fixed cutters.

[0081] like Figures 1 to 14 As shown, further, a first rotating shaft coaxially arranged with the vine conveying and chopping device is rotatably mounted on the frame 19, a first pulley 7 is mounted on the first rotating shaft, a second rotating shaft is rotatably mounted on the vine conveying and chopping device 27, an intermediate shaft 36 is rotatably mounted on the frame 19, a second pulley 15 and a third pulley 16 are mounted on the second rotating shaft, a fourth pulley is mounted on the intermediate shaft 36, the fourth pulley is connected to the third pulley 16 through a belt, and the second pulley 15 is connected to the first pulley 7 through a belt.

[0082] The beneficial effect of adopting this further technical solution is that power is transmitted via a belt from the fourth pulley to the third pulley, and then to the coaxial second pulley. Finally, the belt drives the first pulley to rotate, thereby driving the entire throwing mechanism. The intermediate shaft drives the first rotating shaft, providing power to the auger, chopping device, and throwing mechanism. The belt drive provides overload protection for the peanut harvester, preventing damage from overload.

[0083] The throwing mechanism is secured by the bearing block 1 and the housing 3. The fourth pulley transmits power via a belt to the third pulley 16, which then transmits it to the coaxial second pulley 15. Finally, the belt drives the first pulley 7, thereby driving the entire throwing mechanism. The housing 3 is mounted on the vine conveying and chopping device 27, and a second rotating shaft is rotatably mounted on the housing 3. A fifth pulley is mounted on the intermediate shaft 36 for transmission connection to the engine.

[0084] like Figures 1 to 14 As shown, further, the second vine conveying mechanism includes an agitator device and a chopping device coaxially arranged in sequence along the left-right direction, the chopping device is located on the outside, and the chopping device corresponds to the second conveying channel 28; a second vine collecting fan is provided in the upper end of the second conveying channel 28; the agitator device is used to convey the vines from the grass discharge port of the de-separating unit 24 to the chopping device, and the second vine collecting fan is used to suck the chopped vines into the second conveying channel 28 and convey them to the vine storage device.

[0085] The beneficial effect of adopting the above-mentioned further technical solution is: as an alternative solution to the combination of the agitator device, the chopping device and the throwing mechanism, the combination of the agitator device, the chopping device and the second seedling collecting blower can also realize the transportation of the seedlings discharged from the grass discharge port of the de-separation unit to the seedling storage device, thereby improving applicability.

[0086] like Figures 1 to 14As shown, when the material (peanut vines) falls from the drum 18 into the agitator 2, it is transported by the agitator 2 to the movable knife 11 and the fixed knife 12 for shredding. A lining plate 13 is fixed to the neck of the shell 3 and the fan shell (which can be the side wall of the fan) by square neck bolts to prevent the shell 3 from being worn through. After the material is chopped, it is sucked to the blades 14 by the suction capacity of the throwing mechanism (throwing mechanism), and is thrown out by the centrifugal action of the blades 14. Finally, it is sent to the vine box through the second throwing cylinder 10 and the joint 9, completing the collection, shredding and throwing of the material. Among them, the joint can be a structure with a circle on top and a square hole on the bottom, that is, the top of the joint is a round hole, the bottom of the joint is a square hole, and the square hole is connected to the round hole.

[0087] The peanut harvester provided by the present invention differs from existing commercially available harvester blower systems that use suction and rakes. It is widely used in balers and offers significant reliability advantages over existing technologies that rely on harvester blowers for throwing. By directing material from the drum for throwing, the harvester reduces the amount of material passing through the harvester blower by 80%, allowing the blower to perform only cleaning, thus extending its service life.
