Description

Technical Field

[0001] This invention relates to the field of agricultural machinery and equipment, and in particular to an intelligent adaptive forage harvesting and flattening integrated machine. Background Technology

[0002] With the development of animal husbandry and the increase in the number of herbivorous large livestock such as cattle and sheep, the planting area of ​​forage grass has also increased, especially alfalfa, a high-nutrition, high-protein, and economically valuable forage grass. Ryegrass is known for its tenderness, juiciness, and palatability. It is rich in crude protein, minerals, vitamins, and other nutrients. The moisture content of ryegrass is usually around 70%-80%. At this time, the stems and leaves of ryegrass are tender and the nutritional value reaches its peak. However, excessive moisture also makes it easy to rot and spoil, which is not conducive to storage and transportation. Only by quickly dehydrating the forage grass during its nutrient-rich period, such as making hay or silage, can its nutritional components be preserved to the maximum extent. Dehydrated ryegrass is not only easier to store safely, but also effectively improves the feed intake and digestibility of the material.

[0003] Existing harvesting and flattening machines effectively flatten the stalks of ryegrass during harvesting and flattening, increasing the drying speed by over 50%, shortening the drying time in the pasture, reducing protein loss, improving forage quality, and maximizing the preservation of nutrients for subsequent processing. However, they cannot monitor the moisture content of the forage in real time during the cutting process. This makes it difficult to rationally arrange subsequent drying and storage according to actual conditions, easily leading to mold and spoilage due to improper moisture handling, resulting in nutrient loss, especially vitamins and other easily oxidized nutrients. Furthermore, the proliferation of microorganisms can cause mold and spoilage, reducing the quality and palatability of the forage. Secondly, it is difficult to flexibly adjust the cutting height and angle according to actual conditions. For ryegrass with uneven growth, incomplete harvesting or over-harvesting may occur, affecting the yield and quality of the forage. To solve the above problems, we propose an intelligent adaptive forage harvesting and flattening machine. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This intelligent adaptive hay harvester and calender is equipped with a humidity detection mechanism. During harvesting, it can monitor the moisture content of the hay in real time. Using a moisture meter and probe, it quickly measures the moisture content based on the hay's conductivity or dielectric constant, providing accurate data support for subsequent drying and storage. This avoids improper moisture handling due to a lack of timely moisture information, effectively preventing hay mold and spoilage, minimizing the loss of vitamins and other easily oxidized nutrients, and ensuring high quality and nutritional value of the hay. When excessive moisture content is detected, the machine activates the first air pump, blowing air through the first air pipe, first air chamber, second air chamber, and first one-way valve. The high-speed airflow accelerates airflow across the hay surface, speeding up moisture removal. The speed at which the forage diffuses from its surface into the surrounding air allows for simultaneous harvesting and drying. This timely drying method significantly improves the drying efficiency of the forage, reduces the chance of microbial growth, and further ensures the quality and palatability of the forage. The chopping and flattening mechanisms can precisely adjust processing parameters based on moisture data provided by the humidity detection mechanism. Air is delivered to the sleeve through the second air transmission pipe via the second air pump. The airflow generates blowing force by opening the second one-way valve. The chopping device cuts the forage into appropriate lengths, making it easier for the forage to be subjected to uniform pressure during flattening, better breaking down the tissue structure of the stems and promoting moisture evaporation. The flattening mechanism adjusts the height of the second pressure roller according to the moisture content, precisely controlling the flattening pressure and gap, further improving the drying efficiency and storage quality of the forage.

[0018] 2. This intelligent adaptive forage harvester and flattener integrates a cutting mechanism that, through the rotational connection of a first rotating block, a first rotating shaft, and a second rotating block, as well as universal wheels at the bottom of the base plate, can flexibly adapt to different terrains and forage growth conditions. Operators can precisely select the length of forage to harvest by pushing the first cutting plate up and down via the first electric telescopic rod, based on actual conditions. This effectively avoids the problems of incomplete or over-harvesting when dealing with unevenly growing forage, as seen in traditional equipment, thus improving forage yield and quality. During the cutting process, a baffle is embedded in the groove at the top of the base plate to ensure the stability of the cutting plate. Simultaneously, the first motor drives the cam to rotate, causing the second cutting plate to slide linearly back and forth within the T-shaped groove. The relative motion between the first and second cutting blades creates a stable shearing force, ensuring high efficiency and stability in cutting and further improving harvesting quality.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-10 As shown, an intelligent adaptive forage harvester and flattener includes a frame 1. A shell 12 is fixedly connected to the top side wall of the frame 1. A cutting mechanism 2 for cutting forage is rotatably connected to one side wall of the frame 1. A humidity detection mechanism 3 for detecting and combing the moisture of the forage is fixedly connected to one side wall of the frame 1. A conveying mechanism 4 for conveying forage is fixedly connected to one corresponding end of the inner side of the frame 1. A chopping and conveying mechanism 5 for chopping and conveying forage is fixedly connected to one side wall of the conveying mechanism 4. A flattening mechanism 6 for flattening forage is fixedly connected to the other side wall of the frame 1.

[0032] In this embodiment, the cutting mechanism 2 includes a plurality of first rotating blocks 21 fixedly connected to one end of a frame 1. A first rotating shaft 23 is fixedly connected to the inner side wall of the plurality of first rotating blocks 21. A second rotating block 22 is rotatably connected to the outer side wall of the first rotating shaft 23. The plurality of first rotating blocks 21 are all located between the second rotating blocks 22. A base plate 24 is fixedly connected to one side wall of the plurality of second rotating blocks 22. A plurality of holes are opened at the top of the base plate 24 and a first electric telescopic rod 26 is fixedly connected thereto. A first cutting plate 27 is provided at the telescopic end of the plurality of first electric telescopic rods 26. A baffle 298 is provided at the bottom end of the first cutting plate 27. A slot is opened at the top of the base plate 24 and fits with the baffle 298. A plurality of universal wheels 25 are provided at the bottom end of the base plate 24.

[0033] Specifically, the rotational connection of the first rotating block 21, the first rotating shaft 23, and the second rotating block 22 allows for flexible adaptation to different terrains. Meanwhile, the casters 25 at the bottom of the base plate 24 facilitate its movement and positioning on the ground. The first electric telescopic rod 26 extends to push the first cutting plate 27 up and down, thereby adapting to different grass growth conditions and selecting the length of grass to harvest. Furthermore, the baffle 298 is embedded in the groove at the top of the base plate 24 to ensure the stability of the cutting plate.

[0034] In this embodiment, a plurality of second cutting blades 293 are provided on one side wall of the first cutting plate 27. A T-shaped groove 28 is provided on one end of the first cutting plate 27. A T-shaped slide plate 29 is slidably connected to the inner side of the T-shaped groove 28. A second cutting plate 291 is provided at the top of the T-shaped slide plate 29. A plurality of first cutting blades 292 are provided on one side wall of the second cutting plate 291. The top of the first cutting blade 292 contacts the bottom of the second cutting blade 293. A first fixing frame 294 is provided on both side walls of the first cutting plate 27. A first motor 295 is provided at the top of each of the two first fixing frames 294. A first transmission shaft 296 is provided through the output end of the first motor 295 and is provided on the top of the first fixing frame 294. A cam 297 is provided on the outer side wall of the first transmission shaft 296. The outer side wall of the protruding end of one cam 297 contacts the side wall of one end of the second cutting plate 291, and the outer side wall of the smooth end of the other cam 297 contacts the side wall of the other end of the second cutting plate 291.

[0035] Specifically, the first motor 295 is started, and its output end drives the first transmission shaft 296 to rotate, which in turn causes the cam 297 to rotate. Since the protruding end of one cam 297 is in contact with one end of the second cutting plate 291, and the smooth end of the other cam 297 is in contact with the other end, as the cam 297 rotates, the second cutting plate 291 slides linearly back and forth in the T-shaped slide groove 28. In this way, the first cutting blade 292 and the second cutting blade 293 generate relative motion, forming a shearing force to cut the hay.

[0036] In this embodiment, the humidity detection mechanism 3 includes support plates 31 fixedly connected to the two side walls of the frame 1. A second rotating shaft 35 is rotatably connected to the side wall of one opposite end of the two support plates 31. An eighth motor 397 is provided on one side wall of one support plate 31. The output end of the eighth motor 397 is fixedly connected to one end of the second rotating shaft 35. Support plates 37 are provided at both ends of the outer side wall of the second rotating shaft 35. Multiple support rods 39 are arranged in a circular array at the corresponding ends of the two support plates 37. Multiple combing rods 392 are provided on the outer side wall of the multiple support rods 39. Multiple holes are opened on the outer side wall of the multiple combing rods 392, and a second electric telescopic rod 393 is fixedly connected inside the corresponding hole. A moisture meter 394 is provided at the telescopic end of the second electric telescopic rod 393. A probe 395 is provided at the other end of the moisture meter 394. A soft membrane cover 396 is provided on the outside of the multiple holes opened on the outer side wall of the combing rod 392.

[0037] Specifically, the eighth motor 397 starts, driving the second rotating shaft 35 to rotate, causing the support plate 37 and its support rod 39 to perform circular motion. During the rotation, the combing rod 392 on the support rod 39 combs the pasture on the ground, making the pasture more neatly tilted into the integrated machine for easy cutting. At the same time as the rotation, multiple second electric telescopic rods 393 extend, pushing the moisture meter 394 and probe 395 out from the holes on the outer wall of the combing rod 392 and the soft membrane cover 396. The probe 395 is inserted into the pasture. The moisture meter 394 quickly measures the moisture content based on the pasture's electrical conductivity or dielectric constant. After the test is completed, the second electric telescopic rods 393 retract, and the probe 395 returns to the hole. The soft membrane cover 396 protects the probe 395 and prevents the pasture from getting caught on the probe 395.

[0038] In this embodiment, multiple first one-way valves 391 are provided on the outer walls of multiple support rods 39. The direction of the first one-way valves 391 is perpendicular to the direction of the combing rods 392. A first air chamber 36 is provided inside a second rotating shaft 35. A second air chamber 38 is provided inside a support plate 37. The second air chamber 38 is connected to the first air chamber 36 and multiple support rods 39. A hole is provided on the other side wall of the first air chamber 36 and a first air transmission pipe 34 is fixedly connected thereto. A first support frame 32 is provided on one side wall of another support plate 31. A first air pump 33 is fixedly connected to the inner side wall of the first support frame 32. The output end of the first air pump 33 is fixedly connected to the other end of the first air transmission pipe 34.

[0039] Specifically, when excessive moisture content is detected in the forage, the first air pump 33 starts working, delivering air through the first air transmission pipe 34 to the first air chamber 36, then through the second air chamber 38 into multiple support rods 39, and finally blowing the air out through the first one-way valve 391. The blown airflow further combs the forage, and the high-speed airflow can accelerate the air flow on the surface of the forage, speeding up the diffusion of moisture from the surface of the forage into the surrounding air, thereby achieving simultaneous harvesting and drying.

[0040] In this embodiment, the conveying mechanism 4 includes a second motor 42 fixedly connected to one side wall of the frame 1. The output end of the second motor 42 passes through one end of the frame 1 and is provided with a bidirectional auger 41. The other end of the bidirectional auger 41 is rotatably connected to one end of the frame 1. Mounting plates 49 are provided at both ends of the inner side of the frame 1. A transmission port 491 is opened on one side wall of the mounting plate 49. Two second support frames 45 are provided on one side wall of the mounting plate 49. A third rotating shaft 46 is rotatably connected to the inner side of the two second support frames 45. Multiple transmission rods 47 are arranged in a circular array on the outer side wall of the third rotating shaft 46. Multiple stop bars 48 are provided on one side wall of the mounting plate 49. The multiple stop bars 48 are all located between the multiple transmission rods 47. A third motor 43 is provided on one side wall of the frame 1. The output end of the third motor 43 passes through the frame 1 and is provided with a second drive shaft 44. The other end of the second drive shaft 44 is fixedly connected to one end of the third rotating shaft 46.

[0041] Specifically, the second motor 42 starts, driving the bidirectional auger 41 to rotate. The spiral blades of the bidirectional auger 41 push the cut hay from both sides to the middle, achieving initial conveying and dispersion. Then, the third motor 43 starts, causing the second drive shaft 44 to drive the third rotating shaft 46 to rotate. This causes the transmission rods 47, which are arranged in a circular array on the third rotating shaft 46, to rotate. The hay passes through the transmission port 491 of the mounting plate 49 and is conveyed towards the chopping and conveying mechanism 5 under the pushing of multiple transmission rods 47, the rotation of the bidirectional auger 41, and the blocking and guiding action of multiple baffles 48.

[0042] In this embodiment, the chopping and conveying mechanism 5 includes a second fixed frame 592 fixedly connected to the other side wall of the mounting plate 49. The bottom side wall of the second fixed frame 592 has multiple holes, and a third electric telescopic rod 593 is fixedly connected inside the corresponding holes. The telescopic ends of the multiple third electric telescopic rods 593 are all equipped with a fifth motor 594. The output end of the fifth motor 594 is equipped with a chopping device 595. Two transmission wheels 57 are rotatably connected to one side wall of the inner side of the frame 1. The outer side walls of the two transmission wheels 57 are rotatably connected to the same conveyor belt 58. A fourth motor 56 is provided on one side wall of the frame 1. The output end of the fourth motor 56 passes through the side wall of the frame 1 and is fixedly connected to one end of one of the transmission wheels 57. The outer side wall of the conveyor belt 58 has multiple holes, and a second one-way valve 591 is fixedly connected inside the corresponding holes. Multiple pallets 59 are fixedly connected to the outer wall of the conveyor belt 58. The multiple second one-way valves 591 are all located between the multiple pallets 59.

[0043] Specifically, the fourth motor 56 starts, driving the transmission wheel 57 to rotate, causing the conveyor belt 58 to operate, and conveying the cut hay through multiple pallets 59. The fifth motor 594 starts, driving the shredder 595 to rotate at high speed. The blades of the shredder 595 shred the conveyed hay into appropriate lengths. The shredded hay is more easily subjected to uniform pressure when flattened, which can better break down the tissue structure of the stems, promote moisture evaporation, and dry the hay again through the generated airflow. Subsequently, the shredded hay is conveyed to the flattening mechanism 6 by the conveyor belt 58.

[0044] In this embodiment, a sleeve 54 is fixedly connected to one side wall of the inner side of the frame 1. The sleeve 54 is located inside the conveyor belt 58. A plurality of first slots 55 are opened on the outer side wall of the sleeve 54. A third support frame 51 is provided on one side wall of the frame 1. A second air pump 52 is fixedly connected to the inner side of the third support frame 51. A second air transmission pipe 53 is provided at the output end of the second air pump 52. The other end of the second air transmission pipe 53 passes through one side wall of the frame 1 and is fixedly connected to one end of the sleeve 54.

[0045] Specifically, the second air pump 52 operates, delivering air to the sleeve 54 through the second air transmission pipe 53, and blowing it out through the first slot 55 on the outer wall of the sleeve 54. The airflow is also blown by the second one-way valve 591, which blows the chopped hay into the air and close to the chopping device 595.

[0046] In this embodiment, the flattening mechanism 6 includes a housing 61 with a frame 1 fixedly connected to one side wall of the outer shell 12. Two first pressure rollers 65 are symmetrically rotatably connected to the side wall of opposite ends of the housing 61. One end of each of the two first pressure rollers 65 is provided with a third transmission shaft 63 through the housing 61. The outer side wall of the two third transmission shafts 63 is rotatably connected to the same third transmission bar 64. A bracket 695 is provided on one side wall of the housing 61. A sixth motor 62 is provided on one side wall of the bracket 695. The output end of the sixth motor 62 is fixedly connected to one end of a third transmission shaft 63. A base 693 is provided on the bottom side wall of the housing 61. Multiple holes are opened through the base 693 at the bottom end of the housing 61.

[0047] Specifically, the sixth motor 62 starts up and drives the two first pressure rollers 65 to rotate synchronously through the third transmission shaft 63 and the third transmission bar 64, providing power for flattening the hay. In addition, multiple fourth electric telescopic rods 67 adjust the height of the second pressure roller 691 according to the moisture content of the hay detected by the humidity detection mechanism 3, so that the gap and pressure between the second pressure roller 691 and the first pressure roller 65 can be precisely adjusted.

[0048] In this embodiment, connecting plates 66 are fixedly connected to both ends of the housing 61. Two fourth electric telescopic rods 67 are provided at the bottom of the connecting plates 66. The telescopic ends of the two fourth electric telescopic rods 67 are provided with fourth support frames 68. A seventh motor 692 is provided on one side wall of the two fourth support frames 68 at the same end. A fourth rotating shaft 69 is provided at the output end of the seventh motor 692. Moving grooves 694 are provided on the side walls of both ends of the housing 61. The fourth rotating shaft 69 slides inside the moving grooves 694. A second pressure roller 691 is provided through the housing 61 at the other end of the fourth rotating shaft 69. The groove position of the second pressure roller 691 corresponds to the protruding position of the first pressure roller 65. A discharge port 696 is provided on one side wall of the housing 61. The discharge port 696 is located between the second pressure roller 691 and the first pressure roller 65.

[0049] Specifically, the chopped hay enters the casing 61 and is flattened under the combined action of the first pressure roller 65 and the second pressure roller 691. The first pressure roller 65 rolls the hay into the flattening area, and the second pressure roller 691 applies pressure to the hay, destroying its stem structure. By using pressure to destroy the stem structure of the hay, the moisture evaporation is accelerated, improving the drying efficiency and storage quality of the hay. Finally, the flattened hay is discharged through the discharge port 696.

[0050] It should be noted that this invention is an intelligent adaptive hay harvester and flattener. The user moves the machine to the hay harvesting area. The cutting mechanism 2, through the rotational connection of the first rotating block 21, the first rotating shaft 23, and the second rotating block 22, can flexibly adapt to different terrains. Simultaneously, the universal wheels 25 at the bottom of the base plate 24 facilitate its movement and positioning on the ground. The first electric telescopic rod 26 extends, pushing the first cutting plate 27 up and down to adapt to different hay growth conditions, thus selecting the appropriate length for harvesting. Furthermore, the baffle 298 is embedded in the groove at the top of the base plate 24 to ensure the stability of the cutting plate. Subsequently, the first motor 295 is started, and its output drives the first transmission shaft 296 to rotate, thereby causing the cam 297 to rotate. The protruding end of cam 297 contacts one end of the second cutting plate 291, and the smooth end of another cam 297 contacts the other end. As cam 297 rotates, the second cutting plate 291 slides linearly back and forth within the T-shaped groove 28. This causes relative motion between the first cutting blade 292 and the second cutting blade 293, generating shearing force to cut the forage. Simultaneously, the eighth motor 397 starts, driving the second rotating shaft 35 to rotate, causing the support plate 37 and its support rod 39 to perform circular motion. During rotation, the combing rod 392 on the support rod 39 combs the forage on the ground, making the forage more neatly tilted into the machine for easier cutting. Simultaneously with rotation, multiple second electric telescopic rods 393 extend to measure moisture content. The moisture meter 394 and probe 395 are pushed out from the holes on the outer wall of the combing rod 392 and the soft membrane cover 396, and the probe 395 is inserted into the forage. The moisture meter 394 quickly measures the moisture content based on the electrical conductivity or dielectric constant of the forage. After the test is completed, the second electric telescopic rod 393 retracts, and the probe 395 returns to the hole. The soft membrane cover 396 protects the probe 395 and prevents the forage from hanging on the probe 395. When the moisture content of the forage is detected to be too high, the first air pump 33 starts to work, delivering air through the first air transmission pipe 34 to the first air chamber 36, then through the second air chamber 38 into multiple support rods 39, and finally blowing the air out through the first one-way valve 391. The blown air enters... In the first step, the high-speed airflow accelerates the airflow on the surface of the forage, speeding up the diffusion of moisture from the forage surface into the surrounding air, thus achieving simultaneous harvesting and drying. At the same time, the second motor 42 starts, driving the bidirectional auger 41 to rotate. The spiral blades of the bidirectional auger 41 push the cut forage from both sides to the middle, achieving initial conveying and dispersion. Furthermore, the third motor 43 starts, causing the second drive shaft 44 to drive the third rotating shaft 46 to rotate, causing the transmission rods 47 arranged in a circular array on the third rotating shaft 46 to rotate. The forage is conveyed towards the chopping and conveying mechanism 5 through the transmission port 491 of the mounting plate 49, driven by the multiple transmission rods 47, the rotation of the bidirectional auger 41, and the blocking and guiding action of multiple baffles 48.

[0051] Subsequently, the fourth motor 56 starts, driving the transmission wheel 57 to rotate, causing the conveyor belt 58 to operate, and conveying the chopped hay through multiple pallets 59. At the same time, the second air pump 52 works, delivering air through the second air transmission pipe 53 to the sleeve 54, and blowing it out through the first slot 55 on the outer wall of the sleeve 54. The airflow is also blown by the second one-way valve 591, which opens to generate blowing force, blowing the chopped hay into the air and close to the chopping device 595. At the same time, the third electric telescopic rod 593 lowers the fifth motor 594 and the chopping device 595 to a suitable position, bringing them close to the conveyed hay. The fifth motor 594 starts, driving the chopping device 595 to rotate at high speed. The blades of the chopping device 595 chop the conveyed hay into suitable lengths. The chopped hay is more easily subjected to uniform pressure when flattened, which can better break down the tissue structure of the stems, promote moisture evaporation, and dry the hay again through the generated airflow. Subsequently, the chopped hay is conveyed to the flattening mechanism 6 by the conveyor belt 58.

[0052] After the hay enters the flattening mechanism 6, the sixth motor 62 starts, driving the two first pressure rollers 65 to rotate synchronously through the third transmission shaft 63 and the third transmission bar 64, providing power for the flattening of the hay. Meanwhile, multiple fourth electric telescopic rods 67 adjust the height of the second pressure roller 691 according to the moisture content of the hay detected by the humidity detection mechanism 3, so that the gap and pressure between the second pressure roller 691 and the first pressure roller 65 are precisely adjusted. The chopped hay enters the housing 61 and is flattened under the combined action of the first pressure roller 65 and the second pressure roller 691. The first pressure roller 65 rolls the hay into the flattening area, and the second pressure roller 691 applies pressure to the hay, destroying its stem structure. Using pressure to destroy the stem structure of the hay accelerates moisture evaporation, improves the drying efficiency and storage quality of the hay, and finally discharges the flattened hay through the discharge port 696.
