Description

Technical Field

[0001] The present invention belongs to the technical field of peanut harvesting equipment, and in particular relates to a peanut harvesting device and a peanut harvesting method using the device. Background Art

[0002] Peanuts, a major oil-producing crop, are widely cultivated in my country. When the peanut berries are ripe, they are pulled from the soil using machinery, shaken free of dirt, and then turned over to dry in the sun. Once the berries are dry (to a moisture content of around 10%), they are harvested by detaching them from the seedlings.

[0003] Patent CN201710239993.1 mentions a peanut picking machine that uses staggered comb blades to move back and forth to cut peanut seedlings for picking. However, when cutting the connection between the peanut fruit and the seedling, the roots will be cut off and fall into the fruit, increasing the complexity of subsequent processing. Summary of the Invention

[0004] The present invention addresses the problem that the roots of peanuts are cut off when harvesting peanuts using the cutting method in the prior art, which increases the complexity of subsequent processing. The present invention proposes the following technical solutions:

[0005] A peanut harvesting device, comprising: a first comb plate, a second comb plate, and two limiting assemblies, wherein the limiting assemblies are used to clamp and fix peanut plants passing in a feeding direction, the teeth of the first comb plate and the teeth of the second comb plate being staggered, and the ends of the first comb plate and the second comb plate are each provided with a reciprocating rotating shaft, the ends of the shaft being connected to an external power mechanism, and the two shafts are symmetrically arranged;

[0006] After the limiting component clamps the peanut seedlings on both sides, the two rotating shafts rotate back and forth at the same time to drive the corresponding first comb plate and second comb plate to deflect. The first comb plate and the second comb plate separate the forward and reverse peanut seedlings respectively during the reciprocating process, and comb and pick the peanut fruits from the staggered gaps between the teeth of the first comb plate and the teeth of the second comb plate during the two interlacing processes.

[0007] As a preferred embodiment of the above technical solution, the limiting component includes a power unit and two mounting frames, wherein an extrusion plate is movably inserted inside the mounting frame, and the two extrusion plates are symmetrically arranged. The power unit pushes the two extrusion plates to move to clamp and fix the position of the peanut seedlings.

[0008] As a preferred embodiment of the above technical solution, the angle between the squeezing plate and the mounting bracket is in the range of 30-60 degrees, and the squeezing plate is tilted to push the peanut fruits away from the clamping position and only clamp and fix the peanut seedlings.

[0009] As a preferred embodiment of the above technical solution, the power unit includes a mounting seat, a screw rod and two sliding rods, the surface of the sliding rod is movably connected with a slider fixedly connected to the corresponding extrusion plate, one end of the two screw rods is fixedly connected, and the other end of the screw rod rotates through the mounting seat and extends to the outside, and a moving block is threadedly connected to the end of the screw rod, and a limiting rod is movably inserted in the middle of the moving block, and the two ends of the limiting rod are movably inserted in the two sliders.

[0010] As a preferred embodiment of the above technical solution, the sliding rod and the extrusion plate have the same inclination angle, and the sliding rod is fixedly connected to the mounting seat.

[0011] As a preferred embodiment of the above technical solution, the teeth of the first comb plate and the teeth of the second comb plate are both arranged in a prism shape, and the gap at the intersection of the teeth of the first comb plate and the teeth of the second comb plate gradually increases from the outside to the inside.

[0012] As a preferred embodiment of the above technical solution, an auxiliary component is also included, which includes two groups of connecting frames. The connecting frames in the same group are fixedly connected to the corresponding mounting frames. The connecting frames are located at the teeth gap of the second comb plate, and multiple supporting rollers are rotatably plugged into the inside of the connecting frames.

[0013] As a preferred embodiment of the above technical solution, it also includes a warehouse body, and a feed port, a discharge port and a collection port are respectively provided on both sides and the bottom of the warehouse body. The warehouse body is provided with a transmission device on both sides of the feed port and the discharge port. The peanut seedlings enter from the feed port and are discharged from the discharge port, and the combed and picked peanut fruits fall from the collection port and enter the external collection equipment.

[0014] The peanut harvesting method comprises the following steps:

[0015] S1, feeding;

[0016] The conveying mechanism of the harvesting device collects the dried peanut plants and transports them through the transmission device. The peanut plants enter the bin body from the feed port in a forward or reverse direction.

[0017] S2, clamping and fixation;

[0018] After temporarily stopping the conveyance of the peanut plants, the limiting components on both sides work to fix the peanut plants in the forward or reverse direction respectively;

[0024] The limiting component is reset and the transmission device is started, the peanut plants continue to enter and push the split peanut seedlings out of the bin body and leave from the discharge port, and step S2 is continued until the processing is completed.

[0025] The beneficial effects of the present invention are:

[0026] 1. Peanut seedlings are separated by rotating the staggered first and second comb plates simultaneously. During the two staggering processes of the first and second comb plates, the forward and reverse peanut fruits are combed and picked from the staggered gaps respectively. The roots of the peanut seedlings remain intact and will not be mixed with the fruits, making subsequent processing simpler and more convenient. In addition, with the cooperation of the two limiting components, there is no need to consider the entry direction of the peanut plants, which makes it more applicable and more convenient for batch processing.

[0027] 2. The inclined squeezing plates extend under the push of the power unit. The two squeezing plates clamp and fix the peanut seedlings to facilitate the fruit picking operation. During the extension process, the squeezing plates push the peanut fruits away from the clamping position, and only clamp and fix the peanut seedlings. This can fix the peanut seedlings while avoiding excessive clamping and damage to the peanut fruits.

[0028] 3. The power unit can move multiple extrusion plates at the same time to complete the clamping and fixing of the peanut seedlings, making the clamping and fixing of the peanut seedlings more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings. Example

[0037] Figure 1-Figure 5 In the peanut harvesting device, the peanut harvesting device includes: a first comb plate 11, a second comb plate 12 and two limiting components 20, the limiting components 20 are used to clamp and fix the peanut plants passing in the feeding direction, such as Figure 1 and Figure 2 The direction A is the feeding direction. The teeth of the first comb plate 11 and the teeth of the second comb plate 12 are staggered. The ends of the first comb plate 11 and the second comb plate 12 are both provided with a reciprocating rotating shaft 13. The ends of the rotating shaft 13 are connected to an external power mechanism, and the two rotating shafts 13 are symmetrically arranged.

[0038] After the limiting component 20 clamps the peanut seedlings on both sides, the two rotating shafts 13 rotate back and forth at the same time to drive the corresponding first comb plate 11 and second comb plate 12 to deflect. The first comb plate 11 and the second comb plate 12 separate the forward and reverse peanut seedlings respectively during the reciprocating process, and comb and pick the peanut fruits from the staggered gaps between the teeth of the first comb plate 11 and the teeth of the second comb plate 12 during the two interlacing processes.

[0039] It also includes a warehouse body 40, which is respectively provided with a feed port 41, a discharge port 42 and a collection port 43 on both sides and the bottom of the warehouse body 40. The warehouse body 40 is provided with a transmission device on both sides of the feed port 41 and the discharge port 42. The peanut seedlings enter from the feed port 41 and are discharged from the discharge port 42, and the combed and picked peanut fruits fall from the collection port 43 and enter the external collection equipment.

[0040] When the peanut fruits are harvested, the conveying mechanism of the harvesting device collects the dried peanut plants and transmits them through the transmission device. The peanut plants enter the warehouse body 40 from the feed port 41 in the forward or reverse direction. Then the conveying of the peanut plants is temporarily stopped, and the limiting components 20 on both sides are started to fix the peanut plants in the forward or reverse direction. The external power device drives the two symmetrically arranged rotating shafts 13 to rotate, and the first comb plate 11 and the second comb plate then perform a reciprocating operation. The teeth of the first comb plate 11 and the second comb plate 12 separate the forward and reverse peanut seedlings, and comb and pick them from the staggered gaps between the teeth of the first comb plate 11 and the teeth of the second comb plate 12 during the two interlacing processes. After being picked, the picked peanut fruits fall into the external collection device through the collection port 43. After dust and impurity removal, the dust and dead leaves inside are removed. Then the limiting component 20 is reset and the transmission device is started. The peanut plants continue to enter and push the separated peanut seedlings out of the warehouse body 40 and leave from the discharge port 42. The cycle is continued until the processing is completed.

[0041] The peanut seedlings are split by rotating the staggered first comb plates 11 and the second comb plates 12 at the same time, and the forward and reverse peanut fruits are combed and picked from the staggered gaps during the two staggering processes of the first comb plates 11 and the second comb plates 12. The roots of the peanut seedlings remain intact and will not be mixed in the fruits, making subsequent processing simpler and more convenient. In addition, with the cooperation of the two limiting components 20, there is no need to consider the entry direction of the peanut plants, and the applicability is stronger and more convenient for batch processing.

[0042] The peanut harvesting method comprises the following steps:

[0043] S1, feeding;

[0044] The conveying mechanism of the harvesting device collects the dried peanut plants and transports them through the transmission device. The peanut plants enter the bin body 40 from the feed port 41 in a forward or reverse direction.

[0045] S2, clamping and fixation;

[0046] After temporarily stopping the conveyance of the peanut plants, the limiting components 20 on both sides work to fix the peanut plants in the forward or reverse direction respectively;

[0047] S3. Fruit picking;

[0048] The two symmetrically arranged rotating shafts 13 simultaneously rotate back and forth once, driving the corresponding first comb plates 11 and second comb plates 12 to deflect. The first comb plates 11 and second comb plates 12 separate the peanut seedlings in the forward and reverse directions respectively during the reciprocating process, and the peanut fruits are combed and picked from the interlaced gaps between the teeth of the first comb plate 11 and the teeth of the second comb plate 12 during the two interlacing processes;

[0049] S4, collection;

[0050] The picked peanut fruits fall into the external collection device through the collecting port 43 and are then processed to remove dust and dead leaves from the outside.

[0051] S5, continuous processing;

[0052] The limiting assembly 20 is reset and the transmission device is started. The peanut plants continue to enter and push the split peanut seedlings out of the bin body 40 and out of the discharge port 42. Step S2 is continued until the processing is completed.

[0053] Figure 2-Figure 4 In the figure, the limiting component 20 includes a power unit 23 and two mounting frames 21. The mounting frames 21 are movably connected with extrusion plates 22. The two extrusion plates 22 are symmetrically arranged. The power unit 23 pushes the two extrusion plates 22 to move and clamp and fix the position of the peanut seedlings.

[0054] The angle between the squeezing plate 22 and the mounting frame 21 is in the range of 30-60 degrees. The squeezing plate 22 is tilted to push the peanut fruits away from the clamping position and only the peanut seedlings are clamped and fixed.

[0055] When limiting the position of the peanut plants, the power unit 23 simultaneously pushes the squeezing plates 22 on both sides to move, and the squeezing plates 22 extend tiltedly and push the peanut fruits away from the clamping position, and the two squeezing plates 22 on one side then clamp the peanut plants at the corresponding positions.

[0056] The inclined squeezing plates 22 are extended under the push of the power part 23. The two squeezing plates 22 clamp and fix the peanut seedlings to facilitate the fruit picking operation. During the extension process, the squeezing plates 22 push the peanut fruits away from the clamping position and only clamp and fix the peanut seedlings. This can fix the peanut seedlings while avoiding excessive clamping and damage of the peanut fruits.

[0057] Figure 1 and Figure 6 In the figure, the power unit 23 includes a mounting seat 231, a screw rod 232 and two sliding rods 233. The surface of the sliding rod 233 is movably connected with a slider 234 fixedly connected to the corresponding extrusion plate 22. One end of the two screw rods 232 is fixedly connected, and the other end of the screw rod 232 rotates through the mounting seat 231 to extend to the outside, and the end of the screw rod 232 is threadedly connected with a moving block 235. The middle part of the moving block 235 is movably inserted with a limiting rod 236, and the two ends of the limiting rod 236 are movably inserted in the two sliders 234.

[0058] The sliding rod 233 and the extrusion plate 22 have the same inclination angle, and the sliding rod 233 is fixedly connected to the mounting seat 231 .

[0059] When the limiting component 20 needs to be started, the external power device pushes the screw rod 232 to rotate so that it drives the moving block 235 to move. Under the connection of the limiting rod 236, the two sliders 234 move on the surface of the sliding rod 233 and drive the movement of the extrusion plate 22, thereby completing the clamping and fixing of the peanut seedlings.

[0060] The power unit 23 is capable of simultaneously moving the plurality of squeezing plates 22 to complete the clamping and fixing of the peanut seedlings, making the clamping and fixing of the peanut seedlings more convenient.

[0061] Figure 5 In the embodiment, the teeth of the first comb-shaped plate 11 and the teeth of the second comb-shaped plate 12 are both arranged in a prism shape, and the gap between the teeth of the first comb-shaped plate 11 and the teeth of the second comb-shaped plate 12 at the intersection increases gradually from the outside to the inside.

[0062] The gap between the teeth of the first comb plate 11 and the teeth of the second comb plate 12 gradually increases from the outside to the inside, which can reserve space for the connection between the peanut fruit and the rhizome, making it easier to comb and pick the peanut fruit.

[0063] Figures 1-4 The auxiliary component 30 is also included, and the auxiliary component 30 includes two groups of connecting frames 31. The connecting frames 31 of the same group are fixedly connected to the corresponding mounting frames 21. The connecting frames 31 are located at the tooth gaps of the second comb plate 12, and a plurality of supporting rollers 32 are rotatably inserted inside the connecting frames 31.

[0064] The mounting frame 21 and the supporting roller 32 arranged at the tooth gap of the second comb plate 12 can support the peanut seedlings to prevent the peanut seedlings from falling directly into the external collecting equipment from the collecting port 43. At the same time, the supporting roller 32 can reduce the friction between the peanut seedlings and the mounting frame 21, facilitating the transmission of the peanut seedlings to avoid accumulation in the bin body 40.

[0065] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
