Description

Technical Field

[0001] This invention relates to the field of monitoring technology, and in particular to an intelligent monitoring system for forage harvesting agricultural machinery operations. Background Technology

[0002] Agricultural machinery is a general term for various mechanical equipment used in agricultural production. It is mainly used in crop cultivation and livestock production, as well as in the initial processing and handling of agricultural and livestock products. In hay harvesting, equipment is first used to cut the hay and cause it to fall. Then, hay balers are used to collect, bale, and compress the harvested hay for storage and transportation. Currently, hay balers are primarily mounted on the rear of tractors for operation.

[0003] Existing forage collection methods cannot achieve intelligent monitoring of the forage collection process. They cannot monitor the tractor's movement or the forage baling and collection process, cannot monitor the tractor's status, and cannot accurately monitor the number of bales or the weight of individual bales.

[0004] Moreover, existing hay collecting and baling machines are not convenient for separating small stones mixed in with the hay, and some hay cannot be separated from the collecting rod in time.

[0005] Therefore, in order to address the above problems, a smart monitoring system for forage harvesting agricultural machinery is proposed to solve these problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention develops an intelligent monitoring system for agricultural machinery operations involving forage harvesting. This invention enables intelligent monitoring of the forage harvesting process and the separation of small stones mixed in with the forage.

[0007] The technical solution to the technical problem solved by this invention is as follows: This invention provides a smart monitoring system for forage harvesting agricultural machinery operations, comprising: a power component, a forage harvesting baler, and a forage harvesting component; the power component includes a tractor, the tractor is connected to a cab, cameras are connected to the front and rear ends of the cab respectively, a controller is connected to the top plate of the cab, and the tractor and the cameras are electrically connected to the controller; the forage harvesting baler is connected to the forage harvesting component, the forage harvesting baler is electrically connected to the controller, and a counter and a weighing sensor are installed inside the forage harvesting baler. The counter and the weighing sensor are electrically connected to the controller; the hay collecting assembly includes a cover, the rear end of which is connected to symmetrical L-shaped mounting rods, which are respectively connected to the hay collecting baler; the front end of which is connected to symmetrical L-shaped swing arms, which are respectively connected to the tractor; the cover is connected to an intermediate cylinder, the two ends of which are respectively connected to bearing rings; the symmetrical rings are respectively connected to a set of arc plates, each arc plate is respectively connected to a set of collecting rods; the upper part of the intermediate cylinder is provided with a set of impurity front holes, and the bottom end of the intermediate cylinder is provided with an impurity discharge groove. The camera monitors the front, rear, and driver information to ensure normal operation and traceability. The controller has multiple expansion interfaces, allowing external devices to analyze and process engine data, video data, fuel consumption data, etc., and transmit them synchronously to the platform for visualization. The tractor's engine is equipped with an ECU reader, electrically connected to the controller, which can read engine speed, torque, etc., in real time to determine the tractor's operating status. The controller is equipped with a Beidou positioning module to collect real-time working time, vehicle speed, trajectory, distance, and other information. The hay baler uses existing technology to compact and bale hay. Weighing sensors weigh the hay, and counters calculate the number of bales, enabling monitoring of hay collection. The use of sensors, cameras, and ECU readers for intelligent monitoring of hay collection facilitates smart agriculture. As the collecting rod swings, it contacts the hay, causing the hay to move inside the cover. Due to the combined effects of gravity and centrifugal force, the hay and small stones move inside the cover. Since the small stones are smaller in volume and heavier than the hay, their movement is more intense when they are at the top of the cover, above the middle cylinder. Furthermore, the vibration caused by the tractor's movement intensifies the movement of the small stones, making it easier for them to fall from the impurity front hole into the middle cylinder.

[0008] As an optimization, a wedge-shaped ring is connected to the circular plate on the side of the intermediate cylinder near the discharge trough. Two circular plates of the intermediate cylinder are respectively connected to a large shaft, which is connected to a cross plate. The cross plate is connected to a set of guide rods, and a retaining spring is connected to each guide rod. Each retaining spring surrounds its corresponding guide rod, and each retaining spring is connected to a square tube. Each guide rod is disposed within its corresponding square tube, and a hemisphere is connected to the end of each square tube. Each hemisphere contacts the inclined surface of the wedge-shaped ring. Each square tube is rotatably connected to a set of power plates, and a baffle is connected to each power plate. When the power plate contacts a small stone, the resistance of the baffle causes the small stone to move towards the discharge trough, allowing it to enter and be discharged. When the hemisphere moves upward from under the wedge-shaped ring, the power plate moves away from the discharge trough. When the power plate contacts the small stone, it tilts and does not move the small stone.

[0009] As an optimization, one of the rings is connected to a gear ring, which meshes with a gear. The central shaft of the gear is connected to the cover via a bearing. The central shaft of the gear and the main shaft are respectively connected to synchronous pulleys, and the two ends of the synchronous belt are respectively wrapped around the corresponding synchronous pulleys. The other side of the intermediate cylinder has a circular plate connected to an extension plate, and the central shaft of the gear is connected to the extension plate via a bearing. The movement of the picking rod and the power plate is achieved by using gear ring meshing and a synchronous belt mechanism.

[0010] As an optimization, an intermediate conveying component is also included. This component comprises a U-plate and a scraper conveying assembly. The U-plate is connected to the hay collecting and baling machine, and the scraper conveying assembly is connected to the U-plate. The conveyor belt of the scraper conveying assembly has a set of evenly distributed impurity back holes. The scraper conveying assembly adopts existing technology and includes a conveyor motor, a conveyor belt, two belt shafts, and a set of scrapers. The two belt shafts are respectively bearing-connected to the U-plate. The conveyor motor is connected to the U-plate, and its output shaft is connected to one of the belt shafts. Both ends of the conveyor belt are respectively wrapped around the corresponding belt shafts. The conveyor belt is connected to the set of scrapers. The conveyor motor is electrically connected to a controller. The conveyor belt is inclined, with its lower end positioned at the notch in the cover.

[0011] As an optimization, the U-plate is connected to a mounting block, which is connected to symmetrical guide rods and T-bars. The T-bars pass through a middle block, which is connected to the mounting block via a return spring. The symmetrical guide rods pass through side blocks, and the middle block is rotatably connected to symmetrical stop bars. The symmetrical stop bars are rotatably connected to their corresponding side blocks. The return spring is looped around the T-bars. Some small stones fall from the impurity rear hole onto the U-plate. After contacting the stop bars, they cause the stop bars to swing inward, increasing the tilt angle to facilitate the falling of small stones. Moreover, as the number of small stones changes, the position of the stop bars continuously changes, facilitating the falling of small stones and preventing their accumulation.

[0012] As an optimization, one of the edge blocks is connected to a diagonal rod, which in turn connects to a diagonal block, which is positioned below the waste outlet trough. The movement of the diagonal block is driven by stones falling from the waste outlet trough, thereby changing the position of the stop bar and preventing small stones from accumulating and blocking the area between the edge block and the U-plate.

[0013] As an optimization, the inclined surface of the wedge-shaped ring is in the same direction as the inclination of the inclined block. This allows small stones to fall and move outward after hitting the inclined block, causing the inclined block to move inward, thus expanding the area between the edge block and the U-plate.

[0014] As an optimization, the wedge-shaped ring is wider at the top and narrower at the bottom, which facilitates the movement of the power plate on the lower side towards the discharge trough, thus propelling the small stones forward.

[0015] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects:

[0016] 1. The camera of this invention monitors the front, rear, and driver information to ensure normal operation and traceability; the ECU reader can read engine speed, torque, etc. in real time to determine the tractor's operating status; the controller is equipped with a Beidou positioning module to collect real-time working time, vehicle speed, trajectory, distance, and other information. The hay baler compacts and bales hay, weighs the hay, records the number of bales, and monitors hay collection. By employing sensors, cameras, and ECU readers to achieve intelligent monitoring of hay collection, it facilitates the realization of smart agriculture.

[0017] 2. This device employs a collecting rod that, during its swing, contacts the hay and moves it within the enclosure. Due to gravity and centrifugal force, the hay and small stones move within the enclosure. The small stones, being smaller and heavier than the hay, move more rapidly when they are above the middle cylinder. Furthermore, the vibration from the tractor's movement intensifies the movement of the small stones, facilitating their fall from the impurity inlet into the middle cylinder. The ejector plate moves along the collecting rod, ejecting the hay. When the limiting rod is in the lower half of the V-ring, the limiting rod, under the limiting action of the V-ring, causes the ejector plate to return to its original position. When the collecting rod contacts the hay, the ejector plate is flush against the arc plate, not obstructing hay collection. This facilitates both hay collection and small stone removal.

[0018] 3. When the power plate of this device contacts a small stone, the resistance of the baffle causes the small stone to move closer to the discharge trough, allowing it to enter and be discharged. The power plate then moves away from the discharge trough, tilting upon contact with the small stone and preventing it from moving. Small stones falling from the discharge trough impact the inclined block and move outwards, causing the inclined block to move inwards, thus expanding the area between the side block and the U-plate. When a small stone contacts the stop bar, it causes the stop bar to swing inwards, increasing the tilt angle and facilitating the falling of the small stone. Furthermore, the position of the stop bar continuously changes with the number of small stones, facilitating their fall and preventing accumulation. Attached Figure Description

[0037] like Figures 1 to 11As shown in Embodiment 1: A smart monitoring system for forage harvesting agricultural machinery includes: a power unit 1, a forage harvesting baler 2, and a forage harvesting assembly 4; the power unit 1 includes a tractor 11, the tractor 11 is connected to a cab 12, cameras 13 are connected to the front and rear ends of the cab 12 respectively, and a controller 14 is connected to the top plate of the cab 12; the tractor 11 and the cameras 13 are electrically connected to the controller 14 respectively; the forage harvesting baler 2 is connected to the forage harvesting assembly 4, the forage harvesting baler 2 is electrically connected to the controller 14, and a counter and a weighing sensor are installed inside the forage harvesting baler 2, the counter and the weighing sensor being electrically connected to... The controller 14; the hay collecting assembly 4 includes a cover 42, the rear end of the cover 42 is connected to symmetrical L-mounting rods 41, the symmetrical L-mounting rods 41 are respectively connected to the hay collecting baler 2, the front end of the cover 42 is connected to symmetrical L-swing arms 49, the symmetrical L-swing arms 49 are respectively connected to the tractor 11; the cover 42 is connected to an intermediate cylinder 43, the two ends of the intermediate cylinder 43 are respectively connected to bearing rings 410, the symmetrical rings 410 are respectively connected to a set of arc plates 411, each arc plate 411 is respectively connected to a set of collecting rods 412, the upper part of the intermediate cylinder 43 is provided with a set of impurity front holes 47, and one end of the bottom of the intermediate cylinder 43 is provided with an impurity discharge groove 426. The camera 13 monitors the front, rear, and driver information to ensure normal operation and traceability. The controller 14 wirelessly connects to a host computer, including but not limited to mobile phones, computers, and tablets. The controller 14 has multiple expansion interfaces for connecting external devices to analyze and process engine data, video data, fuel consumption data, etc., and transmits them synchronously to the platform for visualization. The tractor 11 has an ECU reader installed corresponding to its engine, electrically connected to the controller 14, which can read engine speed, torque, etc. in real time to determine the operating status of the tractor 11. The controller 14 is equipped with a Beidou positioning module to collect real-time working time, vehicle speed, trajectory, distance, and other information. The hay baler 2 uses existing technology to compact and bale hay. Weighing sensors weigh the hay, and counters calculate the number of bales, enabling monitoring of hay collection. The use of sensors, camera 13, and ECU readers for intelligent monitoring of hay collection facilitates smart agriculture. During the swinging process, the collecting rod 412 contacts the hay and causes the hay to move inside the cover 42. Due to the action of gravity and centrifugal force, the hay and small stones move inside the cover 42. The small stones are smaller in volume and heavier than the hay. When they are above the cover 42, that is, above the intermediate cylinder 43, the movement speed of the small stones is more intense. Moreover, the tractor 11 vibrates during the movement, which intensifies the movement of the small stones and makes it easier for them to fall from the impurity front hole 47 into the intermediate cylinder 43.

[0038] The intermediate cylinder 43 has a circular plate connected to a wedge ring 417 near the discharge trough 426. The two circular plates of the intermediate cylinder 43 are respectively connected to a large shaft 422. The large shaft 422 is connected to a cross plate 424. The cross plate 424 is connected to a set of guide rods 423. The cross plate 424 is connected to a retaining spring 425 for each guide rod 423. Each retaining spring 425 surrounds the corresponding guide rod 423. Each retaining spring 425 is connected to a square tube 419. Each guide rod 423 is set inside the corresponding square tube 419. The end of each square tube 419 is connected to a hemisphere 418. Each hemisphere 418 contacts the inclined surface of the wedge ring 417. Each square tube 419 is rotatably connected to a set of power plates 420. Each square tube 419 is connected to a baffle 421 for each power plate 420. When the power plate 420 contacts the small stone, under the resistance of the baffle 421, it drives the small stone to move closer to the discharge trough 426, so that the small stone enters the discharge trough 426 and is discharged from the discharge trough 426. When the hemisphere 418 moves upward from under the wedge ring 417, the power plate 420 moves away from the discharge trough 426. When the power plate 420 contacts the small stone, it tilts and does not drive the small stone to move.

[0039] A ring 410 is connected to a gear ring 414, which meshes with a gear 413. The central shaft of the gear 413 is connected to the cover 42 via a bearing. The central shaft of the gear 413 and the main shaft 422 are respectively connected to synchronous pulleys 44. The two ends of the synchronous belt 45 are respectively wrapped around the corresponding synchronous pulleys 44. The other side of the intermediate cylinder 43 is connected to an extension plate, and the central shaft of the gear 413 is connected to the extension plate via a bearing. The movement of the picking rod 412 and the power plate 420 is realized by using gear ring meshing and synchronous belt mechanism transmission.

[0040] It also includes an intermediate transmission component 3, which comprises a U-plate 31 and a scraper transport component 32. The U-plate 31 is connected to the hay collecting and baling machine 2, and the scraper transport component 32 is connected to the U-plate 31. The conveyor belt of the scraper transport component 32 has a set of evenly distributed impurity back holes 33. The scraper transport component 32 adopts existing technology and includes a transport motor, a transport belt, two belt shafts, and a set of scrapers. The two belt shafts are respectively bearing-connected to the U-plate 31. The transport motor is connected to the U-plate 31, and the output shaft of the transport motor is connected to one of the belt shafts. The two ends of the transport belt are respectively wrapped around the corresponding belt shafts, and the transport belt is connected to the set of scrapers. The transport motor is electrically connected to a controller 14. The transport belt is inclined, with its lower end located at the notch of the cover 42.

[0041] The wedge-shaped ring 417 is wider at the top and narrower at the bottom, which facilitates the movement of the power plate 420 on the lower side towards the discharge trough 426, thus driving the small stones forward.

[0042] The workflow of this embodiment is as follows:

[0043] When traveling on the road, the collection boom 412 is at its lowest point, above the road surface. When collecting hay, the adjustment mechanism on the tractor 11 is operated to swing the L-arm 49 so that the collection boom 412 is at its lowest point and in contact with the soil.

[0044] A synchronous pulley 44 can be connected to the engine of the tractor 11 via a mechanism such as a conveyor belt, or it can be provided with a separate power source.

[0045] The tractor 11 and controller 14 are started to move the device. One synchronous pulley 44 rotates, which in turn drives the other synchronous pulley 44 to rotate via the synchronous belt 45. One synchronous pulley 44 drives the gear 413 to rotate, which in turn drives the gear ring 414 to rotate. The gear ring 414 drives the ring 410, the arc plate 411, and the picking rod 412 to rotate. After the picking rod 412 contacts the hay, it causes the hay to move. When small stones move to the top of the impurity hole 47, they fall into the intermediate cylinder 43. The other synchronous pulley 44 drives the main shaft 422 to rotate, which in turn drives the cross plate 424, the retaining spring 425, the guide rod 423, the square tube 419, the power plate 420, and the baffle 4. 21 and hemisphere 418 swing. Under the action of spring 425, hemisphere 418 always contacts the inclined surface of wedge ring 417. When hemisphere 418 moves downward from wedge ring 417, power plate 420 moves towards the discharge trough 426. When power plate 420 contacts small stones, under the resistance of baffle 421, it drives the small stones towards the discharge trough 426, so that the small stones enter the discharge trough 426 and are discharged from the discharge trough 426. When hemisphere 418 moves upward from wedge ring 417, power plate 420 moves away from discharge trough 426. When power plate 420 contacts small stones, it tilts and does not drive the small stones to move. When the collecting rod 412 moves the hay to the gap in the cover 42 above the conveyor belt of the scraper conveyor assembly 32, the hay slides down the collecting rod 412 onto the scraper conveyor assembly 32. Some small stones fall from the impurity rear hole 33 and slide down the U-plate 31 onto the soil. The scraper conveyor assembly 32 then moves the hay into the hay collecting baler 2, achieving compaction, baling, and discharge.

[0046] Example 2: This example further elaborates on Example 1. The U-plate 31 is connected to the mounting block 35. The mounting block 35 is connected to symmetrical guide rods 34 and T-rods 36. The T-rods 36 pass through the intermediate block 37. The intermediate block 37 and the mounting block 35 are connected by a return spring 39. The symmetrical guide rods 34 pass through the side blocks 310 respectively. The intermediate block 37 is rotatably connected to symmetrical stop rods 38. The symmetrical stop rods 38 are rotatably connected to the corresponding side blocks 310. The return spring 39 is looped around the T-rod 36. Some small stones fall from the impurity rear hole 33 onto the U-plate 31. After contacting the stop rods 38, they cause the stop rods 38 to swing inward, increasing the tilt angle to facilitate the falling of small stones. Moreover, as the number of small stones changes, the position of the stop rods 38 continuously changes to facilitate the falling of small stones and prevent their accumulation.

[0047] The workflow of this embodiment is as follows:

[0048] Some small stones fall from the impurity hole 33 onto the U-plate 31. After contacting the stop bar 38, the stop bar 38 swings inward. The stop bar 38 causes the side block 310 to swing along the guide rod 34. The stop bar 38 causes the middle block 37 to move along the T-rod 36. The middle block 37 stretches the reset spring 39. After all the stones have fallen, the reset spring 39 resets, causing the stop bar 38 to reset.

[0049] Example 3: This example further elaborates on Example 1 or 2. One of the edge blocks 310 is connected to a diagonal rod 311, and the diagonal rod 311 is connected to a diagonal block 312. The diagonal block 312 is located below the waste discharge trough 426. Stones falling from the waste discharge trough 426 drive the diagonal block 312 to move, thereby changing the position of the stop bar 38 and preventing small stones from accumulating and blocking the area between the edge block 310 and the U-plate 31.

[0050] The inclined surface of the wedge-shaped ring 417 is in the same direction as the inclination of the inclined block 312. Small stones falling from the wedge block 312 move outwards after impacting it, causing the inclined block 312 to move inwards, thus expanding the area between the edge block 310 and the U-plate 31.

[0051] The workflow of this embodiment is as follows:

[0052] Small stones falling from the waste outlet 426 contact the inclined block 312, causing the inclined block 312 to move inward. The inclined block 312 drives the inclined rod 311 to move, and the inclined rod 311 drives one side block 310 to swing along the guide rod 34. One side block 310 drives one side stop rod 38 to swing inward. The stop rod 38 drives the middle block 37 to move along the T rod 36, thereby realizing the swing of both side stop rods 38. The middle block 37 stretches the return spring 39.

[0053] Example 4: This example further elaborates on Example 1, 2, or 3. At least one side of the cover 42 is connected to an arc ring 46 and a V-shaped ring 48. The arc ring 46 connects to the V-shaped ring 48 to form a closed loop. Each picking rod 412 passes through the top plate 415. The top plate 415 is connected to a limiting rod 416. The limiting rod 416 is located within the area formed by the arc ring 46, the V-shaped ring 48, and the circular ring 410. The limiting rod 416 is positioned between the arc ring 46 and the V-shaped ring 48. When the circular ring 410 forms the area, the ejector plate 415 is in close contact with the arc plate 411, the V-shaped ring 48 corresponds to the upper half of the notch in the cover 42, and the limiting rod 416 is in the upper half of the V-shaped ring 48. Under the action of gravity, the ejector plate 415 moves along the collecting rod 412 and ejects the hay. When the limiting rod 416 is in the lower half of the V-shaped ring 48, under the limiting action of the V-shaped ring 48, the limiting rod 416 drives the ejector plate 415 to reset. When the collecting rod 412 contacts the hay, the ejector plate 415 is in close contact with the arc plate 411 and does not hinder the collection of hay.

[0054] The lower half of the V-ring 48 and the limiting rod 416 are made of magnetic materials with opposite polarities.

[0055] The camera 13 of this invention monitors the front, rear, and driver information to ensure normal operation and traceability. The ECU reader can read engine speed, torque, etc. in real time to determine the operating status of the tractor 11. The controller 14 is equipped with a Beidou positioning module to collect real-time working time, vehicle speed, trajectory, distance, and other information. The hay baler 2 compacts and bales hay, weighs the hay, records the number of bales, and monitors hay collection. By using sensors, camera 13, and ECU reader to achieve intelligent monitoring of hay collection, it is beneficial to realize smart agriculture.

[0056] This device employs a collecting rod 412, which, during its swing, contacts the forage and moves it within the cover 42. Due to gravity and centrifugal force, the forage and small stones move within the cover 42. The small stones, being smaller and heavier than the forage, move more rapidly when positioned above the intermediate cylinder 43. Furthermore, the vibration of the tractor 11 during operation further intensifies the movement of the small stones, facilitating their fall from the impurity front hole 47 into the intermediate cylinder 43. The ejector plate 415 moves along the collecting rod 412, ejecting the forage. When the limiting rod 416 is in the lower half of the V-ring 48, the limiting rod 416, under the limiting action of the V-ring 48, causes the ejector plate 415 to return to its original position. When the collecting rod 412 contacts the forage, the ejector plate 415 is in close contact with the arc plate 411, not obstructing forage collection. This facilitates the collection of forage and the removal of small stones.

[0057] When the power plate 420 of this device contacts a small stone, under the resistance of the baffle 421, it drives the small stone to move closer to the discharge trough 426, allowing it to enter and be discharged. The power plate 420 then moves away from the discharge trough 426, tilting upon contact and preventing further movement of the stone. Small stones falling from the discharge trough 426 strike the inclined block 312 and move outwards, causing the inclined block 312 to move inwards, thus expanding the area between the side block 310 and the U-plate 31. When a small stone contacts the stop bar 38, it causes the stop bar 38 to swing inwards at a larger angle, facilitating the falling of the small stone. Furthermore, the position of the stop bar 38 continuously changes with the number of small stones, further facilitating their fall and preventing accumulation.

[0058] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
