Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, in particular to an adjustable two-ridge four-row opposite-grouping peanut seedling turning harvester. Background Art

[0002] Peanuts, as a major oil crop, are widely planted throughout the country. Peanut harvesting is the last link in its production activities. The quality of the harvesting operation directly affects the peanut yield. Peanut harvesters, as an important tool for peanut harvesting, directly affect the peanut harvesting efficiency.

[0003] Existing peanut digging and spreading machines can only lay peanuts neatly in ridges in the field, resulting in the moisture content of the peanuts in the lower drying layer being much higher than that in the upper drying layer. The drying effect is poor, causing the peanuts in the lower layer to become moldy, which is not conducive to preservation and storage, resulting in a reduced peanut harvest. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an adjustable two-ridge four-row opposite-collecting peanut vine turning harvester to solve the problem of different moisture contents of upper and lower layers of peanuts when peanuts are laid out for drying during the peanut crop harvesting process.

[0011] Preferably, the flip assembly includes two guide bars, the two guide bars are fixedly connected to the clamping and conveying unit bracket, the bars of the guide bars are distributed in a stepped manner, and the two guide bars are mirror-imaged.

[0012] Preferably, the pressing assembly includes two pressing roller brackets, both of which are rotatably connected to the frame, the bottoms of the two pressing roller brackets are fixedly connected to pressing roller support bearing seats, the pressing roller body is rotatably connected between the two pressing roller support bearing seats, the tops of the pressing roller brackets are rotatably connected to an adjustable stud, and the adjustable stud is threadedly connected to the frame.

[0013] Preferably, a plurality of annular through holes are provided on the surface of the excavating blade seat, an oblique edge is provided on the front side of the excavating blade body, and the opening angle of the front side of the excavating blade body is 110 degrees.

[0014] Preferably, the two adjacent lifting chains are distributed in a Y shape, and the front side spacing between the two adjacent lifting chains is greater than the rear side spacing.

[0015] Preferably, both left and right ends of the plurality of driven sprockets are fixedly connected to a bevel gear set, and the bottom end of the bevel gear set is fixedly connected to the plurality of clamping drive sprockets.

[0016] Working principle: The user first connects the peanut rice harvester to the tractor through the three-point suspension frame on the front side of the frame, and connects the gearbox to the rear power output shaft of the tractor. According to the characteristics of the peanut variety and the actual conditions of the soil, the bolts at the connection between the digging shovel handle seat and the digging shovel handle body are removed, and the connection position of the two is changed to achieve control of the digging depth to meet the different digging depth requirements of peanut harvesting. When it is necessary to adjust the digging shovel's entry angle into the soil, the multiple circular through holes opened on the surface of the digging shovel seat are used to adjust the installation angle of the digging shovel body and the digging shovel seat, so that the digging shovel can better adapt to the soil conditions when entering the soil.

[0017] When the tractor pulls the harvester forward, the excavation blade body slides into the soil through the oblique edge and the opening angle of the blade, reducing the resistance during excavation and is used to cut off the peanut roots and loosen the soil.

[0018] The rear output shaft of the tractor drives the gearbox to rotate, and the gearbox drives the driving sprockets on both ends to rotate. The driving sprocket drives the driven sprocket to rotate through the chain, and the driven sprocket drives the clamping drive sprocket to rotate through the bevel gear set, so that the lifting chain starts to circulate and realizes the clamping and transportation of peanut vines.

[0019] During use, if the peanut plants are tall, screw in the flower basket screws appropriately to shorten the length of the connection between the clamping and conveying components and the frame, thereby increasing the clamping height and avoiding pulling the peanut vines during transportation to prevent the vines from breaking; if the peanut plants are short, unscrew the flower basket screws to increase the connection length, reduce the clamping height, and enhance the stability of the peanut plant clamping. At the same time, the angle of the lifting chain will also change with the adjustment of the flower basket screws, so that the collision effect between the peanut plants and the bottom soil-beating strips will change, further optimizing the soil removal function. In addition, the user adjusts the length of the adjustable support rod according to different ridge spacing. At this time, the clamping and conveying body is moved by rotating the rollers on the frame, thereby changing the spacing between the two clamping and conveying bodies, so that the clamping and conveying components can adapt to peanuts in different planting patterns. In the process of the peanut plants being clamped and conveyed by the lifting chain, they will continuously collide with the soil-beating strips fixed at the bottom. During the collision, the soil attached to the peanut fruits and roots will be shaken off, realizing efficient soil removal.

[0020] When the whole peanut plant reaches the guide grid area along the lifting chain, the peanut fruit will first contact the grid. As the peanut fruit falls step by step, the falling speed will be slowed down due to the obstruction each time it passes through a grid. However, the peanut vines are located at the back and are relatively soft, so they fall relatively quickly. In this process, the peanut plant gradually completes the posture adjustment, and finally realizes the inverted laying form with the peanut vines at the bottom and the fruit at the top. The two rows of peanuts are laid opposite each other and lean against each other to form a triangular structure after landing. The two groups of peanut roots are on top. This laying method increases the gaps between the peanuts, improves the ventilation effect, can effectively reduce the mildew of the peanuts due to moisture, facilitates the subsequent collection and storage, and also improves the quality of the peanuts after harvest.

[0021] The user turns the adjustable stud to rotate the pressing roller bracket around the connection point with the frame. During the rotation, the support angle of the pressing roller body changes, and the height of the pressing roller can be adjusted at the same time. The pressing roller presses down to level the soil, forming a surface that is conducive to drying peanuts and effectively avoiding water accumulation in the drying area.

[0022] The present invention provides an adjustable two-ridge four-row opposite peanut harvester.

[0023] Beneficial effects:

[0024] 1. The present invention uses a guide bar design of a flip assembly, and the bars of the two guide bars are distributed in a stepped manner. When the whole peanut plant is transported to the guide bars by the clamping and conveying assembly, the peanut fruits are blocked step by step by the bars, and the falling speed gradually slows down, thereby realizing an inverted laying form of peanut vines at the bottom and fruits at the top. The two rows of peanuts are laid opposite to each other and lean against each other, forming a triangular structure with the ground after landing. The two groups of peanut roots are placed on top, which is convenient for ventilation and drying, and reduces mildew.

[0025] 2. The present invention sets an oblique blade with an opening angle of 110 degrees on the front side of the excavating blade body, and multiple annular through holes on the surface, so that the excavating blade can slide into the soil, reducing the forward resistance of excavation. The installation angle of the excavating blade body and the excavating blade seat can be changed through the annular through holes, thereby controlling the angle of the excavating shovel entering the soil. The excavating shovel handle body, the excavating shovel handle seat and the excavating shovel seat are connected by bolts, and the excavating depth and the left and right excavation spacing can be adjusted, thereby adapting to the excavation depth requirements of different varieties of peanuts and improving the excavation operation effect.

[0026] 3. The present invention ensures the tensioning of the lifting chain through the tensioning pulley, realizes stable clamping and conveying of peanut vines and fruits, and does not break the peanut vines. The two adjacent lifting chains are distributed in a Y shape, and the front side spacing is larger than the rear side spacing, which facilitates the whole peanut plant to better enter the clamping area at the initial stage of transportation. As the transportation process gradually clamps, the spacing of the clamping and conveying units can be adjusted by the adjustable support rod to adapt to different ridge spacing requirements.

[0027] 4. The present invention adjusts the angle between the clamping and conveying unit bracket and the frame through the flower basket screw, thereby adjusting the clamping height and the chain lifting angle. When the peanut plant is taller, the flower basket screw is screwed in to shorten the length of the connection between the clamping and conveying component and the frame, thereby increasing the clamping height and avoiding excessive pulling of the peanut vines during the clamping and conveying process, thereby preventing the vines from breaking and ensuring that the entire peanut plant can be smoothly conveyed. If the peanut plant is shorter, the flower basket screw is unscrewed to increase the connection length. At this time, the clamping height is reduced, which allows the clamping and conveying component to grasp the peanuts more stably, enhances the firmness of the clamping, reduces the falling of peanuts during the conveying process, and improves the integrity and efficiency of the harvest.

[0028] 5. The present invention achieves soil removal by clamping multiple soil-beating bars fixedly connected to the bottom of the conveying body, which collide with the peanut plants during the whole peanut plant transportation process, shake off the soil attached to the peanut fruits, and avoid the peanuts from becoming moldy and deteriorating due to residual soil.

[0029] 6. The present invention drives the pressing roller bracket to rotate by rotating the adjustable stud, thereby adjusting the pressing depth and support angle of the pressing roller body, thereby optimizing the soil state, ensuring the peanut drying environment, promoting ventilation, and enabling the harvester to adapt to operating conditions of different terrains and soil moisture, thereby improving the versatility of the equipment.

[0039] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Please see the attached Figure 1 -Attached Figure 3 An embodiment of the present invention provides an adjustable two-ridge four-row opposite-grouping peanut seedling turning harvester, comprising a frame 1, a three-point suspension frame fixedly connected to the front side of the frame 1, a plurality of digging components 2 are arranged on the front side of the bottom of the frame 1, a transmission component 3 is arranged on the top of the frame 1, a clamping and conveying component 4 is arranged on the top of the frame 1, a turning component 5 is arranged on the rear side of the clamping and conveying component 4, and a suppression component 6 is arranged on the rear side of the bottom of the turning component 5.

[0041] Specifically, when in use, the vehicle is connected to the tractor via a three-point suspension frame, and the gearbox 3-1 is connected to the rear power output shaft of the tractor to provide power as a whole.

[0042] See attached Figure 3 and attached Figure 5 The excavation assembly 2 includes an excavation shovel handle seat 2-4, which is fixedly connected to the frame 1. The bottom of the excavation shovel handle seat 2-4 is fixedly connected to the excavation shovel handle body 2-3, the bottom of the excavation shovel handle body 2-3 is fixedly connected to the excavation blade seat 2-2, and the bottom of the excavation blade seat 2-2 is fixedly connected to the excavation blade body 2-1.

[0043] Specifically, before harvesting peanuts, the user can change the connection position of the digging shovel handle seat 2-4 and the digging shovel handle body 2-3 by removing the bolts on the digging shovel handle seat 2-4 and the digging shovel handle body 2-3 according to actual needs, thereby changing the digging depth. When the digging shovel's entry angle needs to be changed, the annular through hole on the digging shovel blade seat 2-2 is used to adjust the installation angle of the digging shovel blade body 2-1 and the digging shovel blade seat 2-2. Then, the tractor connected to the harvester is started, and the tractor pulls the whole forward. The digging shovel blade body 2-1 penetrates into the soil in the form of sliding cuts through the front bevel edge and the opening angle of 110 degrees, which can effectively reduce the forward resistance of digging, cut off the peanut roots and loosen the soil, thereby digging the peanuts out of the soil.

[0044] See attached Figure 2 and attached Figure 6 The transmission assembly 3 includes a gearbox 3-1, which is fixedly connected to the frame 1. The left and right ends of the gearbox 3-1 are fixedly connected to driving sprockets 3-2. The bottoms of the two driving sprockets 3-2 are each provided with a driven sprocket 3-3, and chains are provided between adjacent driving sprockets 3-2 and driven sprockets 3-3.

[0045] Specifically, the user first connects the peanut rice turning harvester to the tractor through the three-point suspension frame on the front side of the frame 1. The power output shaft at the rear of the tractor rotates to drive the gearbox 3-1. The gearbox 3-1 drives the driving sprockets 3-2 on the left and right sides to rotate synchronously. When the driving sprocket 3-2 rotates, it drives the driven sprocket 3-3 at the bottom to rotate through the chain. The driven sprocket 3-3 drives the clamping drive sprocket 4-2 through the bevel gear set, and then drives the lifting chain 4-6 to operate, thereby realizing the clamping and transportation of peanuts.

[0046] See attached Figure 1 , Attachment Figure 3 and attached Figure 7 The clamping and conveying assembly 4 includes a basket screw 4-10, which is fixedly connected to the frame 1. Two clamping and conveying bodies 4-1 are fixedly connected to the rear side of the basket screw 4-10. A clamping and conveying single bracket 4-9 is fixedly connected between the two clamping and conveying bodies 4-1. An adjustable support rod 4-8 is fixedly connected between the two clamping and conveying bodies 4-1. A plurality of soil-beating strips 4-5 are fixedly connected to the bottom of the clamping and conveying body 4-1. A plurality of rollers 4-7 are rotatably connected to the front and rear sides of the two clamping and conveying bodies 4-1, and the plurality of rollers 4-7 are tightly fitted between the frame 1.

[0047] Specifically, the user can control the clamping height by turning the basket screws 4-10 according to the actual situation of the peanut plants to change the length of the connection between the clamping and conveying components 4 and the frame 1. If the peanut plants are taller, screw in the basket screws 4-10 to shorten the length of the connection between the clamping and conveying components 4 and the frame 1, thereby increasing the clamping height and avoiding pulling the peanut vines. If the plants are shorter, unscrew the basket screws 4-10 to increase the connection length, thereby reducing the clamping height and enhancing the clamping stability. While adjusting the height, the angle of the lifting chain 4-6 also changes accordingly, affecting The collision effect between the peanut plants and the soil-beating strips 4-5 optimizes the soil removal function. According to different ridge spacings, the user adjusts the length of the adjustable support rod 4-8, so that the clamping and conveying body 4-1 moves on the frame 1 through the roller 4-7, and changes the spacing between the two clamping and conveying bodies 4-1, so that the clamping and conveying assembly 4 can adapt to peanuts in different planting patterns. During the conveying process, the peanut plants collide with the soil-beating strips 4-5 fixed at the bottom, shaking off the attached soil blocks, realizing the soil removal function, ensuring that the entire clamping and conveying process is carried out efficiently and stably, and improving the quality and efficiency of peanut harvesting.

[0048] See attached Figure 1 , Attachment Figure 3 and attached Figure 7 A plurality of clamping drive sprockets 4-2 are rotatably connected to the bottom of the clamping conveying body 4-1, a tensioning wheel 4-3 is provided on the rear side of the plurality of clamping drive sprockets 4-2, a clamping sprocket 4-4 is provided on the rear side of the plurality of tensioning wheels 4-3, and the plurality of tensioning wheels 4-3 and the clamping sprocket 4-4 are all rotatably connected to the clamping conveying body 4-1, and a lifting chain 4-6 is provided between adjacent clamping drive sprockets 4-2, tensioning wheels 4-3 and clamping sprockets 4-4.

[0049] Specifically, after the user starts the peanut harvester, the transmission component 3 transmits power to the clamping drive sprocket 4-2, and the clamping drive sprocket 4-2 drives the connected lifting chain 4-6 to operate, and the lifting chain 4-6 starts to circulate, thereby achieving the clamping and transportation of the peanuts. The tensioner 4-3 can adjust the tension of the lifting chain 4-6 to ensure that the lifting chain 4-6 always maintains an appropriate tension, stably clamps the peanuts, and ensures that the peanuts can be transported continuously and stably. As the lifting chain 4-6 operates, the peanuts are transported from the digging component 2 to the subsequent turning component 5.

[0050] See attached Figure 2 and attached Figure 7 The flip assembly 5 includes two guide bars 5-1, which are fixedly connected to the clamping and conveying monomer bracket 4-9. The bars of the guide bars 5-1 are distributed in a stepped manner, and the two guide bars 5-1 are mirror-imaged.

[0051] Specifically, when the whole peanut plant is clamped and conveyed to the flipping component 5 by the lifting chain 4-6 of the clamping and conveying component 4, since the two guide bars 5-1 are fixedly connected to the clamping and conveying single bracket 4-9 and are mirrored, the peanut plant enters the guide bar 5-1 area, and the peanut fruit first contacts the bar. In the step-by-step falling process, the falling speed will be slowed down due to the obstruction after each level of the bar. The peanut vines are located at the back and are relatively soft, so the falling speed is relatively fast. In this process, the peanut plant gradually completes the posture adjustment, and the peanut vines are placed at the bottom and the fruits are placed on the top in an inverted manner. The two rows of peanuts are laid opposite each other and lean against each other to form a triangular structure after landing. The two groups of peanut roots are on top, which increases the gap between the peanuts and improves the ventilation effect. It can effectively reduce the mildew of peanuts due to moisture, create good conditions for drying peanuts, facilitate subsequent collection and storage, and also improve the quality of peanuts after harvest.

[0052] See attached Figure 2 and attached Figure 8 The pressing assembly 6 includes two pressing roller brackets 6-3, and the two pressing roller brackets 6-3 are rotatably connected to the frame 1. The bottoms of the two pressing roller brackets 6-3 are fixedly connected to the pressing roller support bearing seats 6-2, and the pressing roller body 6-1 is rotatably connected between the two pressing roller support bearing seats 6-2. The top of the pressing roller bracket 6-3 is rotatably connected to an adjustable stud 6-4, and the adjustable stud 6-4 is threadedly connected to the frame 1.

[0053] Specifically, when the adjustable stud 6-4 is rotated, the pressing roller bracket 6-3 rotates at the connection point of the frame 1, thereby changing the support angle of the pressing roller body 6-1 and adjusting the pressing depth. If the soil is relatively loose, the user will unscrew the adjustable stud 6-4 to increase the inclination angle of the pressing roller bracket 6-3, so that the pressing roller body 6-1 penetrates the soil with greater pressure, compacts the soil, and reduces soil voids. If it is necessary to move the pressing roller body 6-1 downward, rotate the adjustable stud 6-4 to move it downward, reduce the pressing depth of the pressing roller body 6-1, and avoid soil compaction. The pressing roller body 6-1 moves forward with the harvester to compact the excavated soil, level the land, and form a surface that is conducive to peanut drying, avoiding water accumulation in the drying area, and can adapt to working environments with different terrains and soil moisture, thereby improving the versatility and adaptability of the peanut harvester.

[0054] See attached Figure 5 A plurality of annular through holes are provided on the surface of the excavating blade seat 2-2, and an oblique edge is provided on the front side of the excavating blade body 2-1. The opening angle of the front side of the excavating blade body 2-1 is 110 degrees.

[0055] Specifically, a plurality of annular through holes are provided on the surface of the excavating shovel seat 2-2. The user can adjust the matching angle between the excavating shovel body 2-1 and the excavating shovel seat 2-2 by changing the installation position of the excavating shovel body 2-1 in these annular through holes, thereby controlling the angle of the excavating shovel entering the soil. When excavating, the bevel blade can reduce the forward resistance of excavation by sliding into the soil, making it easier for the excavating shovel to enter the soil. The opening angle of 110 degrees allows the soil to flow smoothly to both sides along the bevel blade during the excavation process, avoiding soil accumulation in front of the shovel, ensuring a smooth excavation process, and helping to completely dig the peanut plants out of the soil, reducing damage to the peanut roots and fruits.

[0056] See attached Figure 6 The two adjacent lifting chains 4-6 are distributed in a Y shape, and the front side spacing of the two adjacent lifting chains 4-6 is larger than the rear side spacing.

[0057] Specifically, peanuts are dug out by the digging device 2, and at this time, the two adjacent lifting chains 4-6 are moving. The larger front side spacing of the Y-shaped lifting chains 4-6 allows the whole excavated peanut plant to smoothly enter the clamping area between the two lifting chains 4-6, and does not cause the peanut plant to be stuck or difficult to enter due to the small spacing. As the peanut plant is gradually transported backward under the drive of the lifting chains 4-6, the design of the smaller rear side spacing allows the lifting chains 4-6 to gradually clamp the peanut plant, ensuring that the peanut plant will not fall during the transportation process, ensuring the stability and reliability of the peanut transportation, thereby realizing the smooth transportation of the peanuts from the digging device to the subsequent turning device 5, ensuring the smooth progress of the entire peanut harvesting process.

[0058] See attached Figure 6 The left and right ends of the multiple driven sprockets 3-3 are fixedly connected with a bevel gear set, and the bottom end of the bevel gear set is fixedly connected to the multiple clamping drive sprockets 4-2.

[0059] Specifically, the user starts the tractor, and the tractor power is transmitted to the gearbox 3-1, and the gearbox 3-1 drives the driving sprocket 3-2 to rotate. Multiple driving sprockets 3-2 drive the driven sprocket 3-3 through the chain, and the driven sprocket 3-3 drives the bevel gear groups on the left and right sides to rotate. When the bevel gear groups rotate, they drive the clamping drive sprocket 4-2, thereby driving the lifting chain 4-6 to operate, and then the clamping and conveying device 4 can clamp the peanut vines and convey them, so that the peanuts dug out from the digging device are smoothly clamped and conveyed to the subsequent process, ensuring the continuity and efficiency of the entire peanut harvesting operation.
