Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a tractor implements working depth monitoring device. Background Technology

[0002] A reversible plow is a tillage implement used in conjunction with a high-powered tractor. It mainly consists of a plow frame, plow body, depth limit wheel, and hydraulic reversing mechanism. Its core feature is its two symmetrical plow bodies. During operation, a hydraulic system drives the entire plow frame to rotate 180°, alternatingly turning the soil. This design completely solves the problem of traditional moldboard plows needing to return empty at the end of the field to create open and closed furrows. After the tractor completes one pass, the reversible plow automatically reverses direction, ensuring the soil clods always turn in the same direction, resulting in a smooth, furrow-free surface. It can also operate continuously, significantly improving work efficiency and soil coverage. Reversible plows are particularly suitable for clay soils, sloping lands, and tillage after straw return. With depth limit adjustment and overload protection devices, they can maintain consistent tillage depth and reduce implement wear, making them an important implement in modern conservation tillage and precision agriculture.

[0003] Currently, most tillage depth monitoring in the industry uses gyroscope-based depth sensors. This approach uses the tractor body as a reference and indirectly calculates the tillage depth through the vehicle's pitch angle. However, in actual operation, when the tractor travels on uneven fields, the vehicle's pitch angle changes frequently, causing the gyroscope's measurement reference to shift, resulting in a large error in tillage depth measurement and failing to accurately reflect the depth of the plow. Furthermore, these sensors are susceptible to interference from vehicle vibration and attitude changes, exhibiting poor stability and failing to meet the high-precision requirements of precision agriculture for tillage depth monitoring. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a tractor implement working depth monitoring device.

[0005] The technical solution adopted to solve the above technical problems is: to provide a tractor implement working depth monitoring device, including a plow connection assembly, a second connecting hollow column is rotatably connected to one side of the plow connection assembly, a second fixed shaft is fixedly connected to one end of the second connecting hollow column, and a reversible plow body is fixedly connected to the other end of the second connecting hollow column; A mounting frame assembly is fixedly connected to the main body of the reversible plow. Two main monitoring mechanisms are mounted on the mounting frame assembly. The mounting frame assembly is used to connect the main body of the reversible plow and the two main monitoring mechanisms. A probe rod assembly is rotatably connected to each of the two main monitoring mechanisms.

[0006] Furthermore, the plow attachment connection assembly includes a first connecting hollow column, a multi-hole connecting frame rod is fixedly connected to the top center of the first connecting hollow column, and rotating connection assemblies are fixedly connected to both ends of the bottom of the first connecting hollow column. A first fixed shaft is installed on the top of the multi-hole connecting frame rod, and a hydraulic tilting drive assembly is rotatably connected to the first fixed shaft. A rotating connecting sleeve is installed at the output end of the hydraulic tilting drive assembly, and the rotating connecting sleeve is sleeved on the second fixed shaft. A rotating connecting shaft is fixedly connected to the center of one side of the first connecting hollow column.

[0007] With the above technical solution, before use, the plow is installed on agricultural machinery such as tractors through the multi-hole connecting frame rod and two rotating connecting components in the plow connecting assembly. When flipping, the hydraulic flipping drive assembly pulls the second connecting hollow column, which in turn drives the second fixed shaft to rotate on the rotating connecting shaft, so that the entire flipping plow body flips over, and multiple plow body components on the other side contact the ground to work.

[0008] Furthermore, the second connecting hollow column has a through hole corresponding to the rotating connecting shaft, and an integral sleeve is fixedly connected to the inner wall of the second connecting hollow column and sleeved onto the outer wall of the rotating connecting shaft.

[0009] Through the above technical solution, the second connecting hollow column can be rotated and adjusted around the rotating connecting shaft to realize the flipping of the plow body assembly. The integrated tube sleeve can strengthen the stability of the rotating connection. When rotating, the integrated tube sleeve can withstand more support force, thereby supporting the entire flipping plow body.

[0010] Furthermore, the reversible plow body includes a plow fixing main rod fixedly connected to one end of the second connecting hollow column, and multiple plow extension support rods are fixedly connected to the plow fixing main rod, with a plow body assembly installed at the other end of each of the multiple plow extension support rods.

[0011] With the above technical solution, during operation, when the reversible plow enters the soil for cultivation, multiple plow body components will move downward as the depth of penetration increases, and turn over the soil along the arc surface of the plow body components. Moreover, the multiple plow body components are not on the same straight line. During operation, rows of soil will be turned over in sequence, improving the soil turning efficiency.

[0012] Furthermore, the mounting bracket assembly includes two main mounting plates mounted on the reversible plow body. Each of the two main mounting plates is provided with an arc-shaped adjustment hole, multiple mounting positioning holes, and two mounting fixing holes. The multiple mounting positioning holes are used to fix the monitoring mechanism, and the two mounting fixing holes are used to mount the two main mounting plates on the reversible plow body. A reinforcing connecting plate is fixedly connected between the two main mounting plates.

[0013] With the above technical solution, during installation, the entire mounting frame assembly is installed and fixed on the reversible plow body through two mounting holes and bolt and nut assemblies. At the same time, the connecting plate is reinforced to strengthen the stability of the connection between the two main mounting plates. The design includes arc-shaped adjustment holes and multiple mounting positioning holes, which are suitable for adjusting the angle of the monitoring mechanism and installing it in different positions, thus enabling it to adapt to more different models of plows.

[0014] Furthermore, the monitoring mechanism includes a detection mechanism connecting frame. Two sets of mounting bolt assemblies are fixedly connected to the bottom of the detection mechanism connecting frame, and a fixed round rod is fixedly connected to the top of the detection mechanism connecting frame. An inner fixing plate and an outer fixing plate are respectively installed on both sides of the detection mechanism connecting frame. A transmission pin is provided between the inner fixing plate and the outer fixing plate. An encoder bracket is provided on the other side of the inner fixing plate. A rotary transmission coupling is installed inside the encoder bracket at one end of the transmission pin, and an encoder body is installed at the other end of the rotary transmission coupling.

[0015] With the above technical solution, during operation, when the reversible plow is used for tilling, the plow's soil-penetrating component moves downward as the soil penetration depth increases, thereby driving the main body of the probe rod to rotate downward. As the main body of the probe rod drives the transmission pin and the rotary transmission coupling to rotate, the encoder body collects the rotation angle signal of the main body of the probe rod in real time. Through the preset angle-tillage depth conversion formula, the real-time soil penetration depth of the plow can be directly calculated. When facing uneven fields, with the main body of the plow as a reference, without being affected by other factors, only the bottom depth of the plow body assembly and the value between the end of the probe rod contacting the ground are controlled, and the stability of this value is ensured, thus achieving a stable distance of the plow penetrating the ground.

[0016] Furthermore, the detection mechanism connecting frame is provided with circular through holes and grooves corresponding to the fixed round rod and the transmission pin, respectively. The inner fixing plate, the outer fixing plate and the encoder bracket are all fixed to the detection mechanism connecting frame by bolts and nuts. The detection mechanism connecting frame is provided with multiple limiting holes, and the encoder body is an absolute encoder.

[0017] Through the above technical solution, the circular through hole ensures that a fixed circular rod can be inserted, the groove is used to install the transmission pin, and the limiting hole on the connecting frame of the detection mechanism is divided into an upper part and a lower part. The upper part of the limiting hole can adjust the lower limit position of the detection rod according to the soil penetration depth range of the plow, while the lower part of the limiting hole is used to limit the lifting height of the detection rod to avoid interference with other parts of the plow during operation. The absolute encoder can directly output the rotation angle value of the detection rod without additional calibration, and the angle resolution is not less than 0.1°, which meets the accuracy requirements for tillage depth measurement.

[0018] Furthermore, the probe rod assembly includes a probe rod body fixedly connected to a transmission pin shaft, a round rod connecting shaft seat fixedly connected to the probe rod body, and a return spring installed between the round rod connecting shaft seat and the fixed round rod.

[0019] With the above technical solution, as the plow's soil-penetrating component gradually penetrates the soil, it drives the main body of the probe rod to rotate downwards. Simultaneously, the return spring is stretched through the round rod connecting shaft seat. The elasticity of the return spring keeps the main body of the probe rod in close contact with the ground. The end of the probe rod can be fitted with a suitable contact head according to the plow model to ensure a good fit with the plow's soil-penetrating component and improve the accuracy of angle acquisition. Also, depending on the plow or the depth of penetration, the fixed round rod can be inserted into different holes to ensure that the return spring between the fixed round rod and the round rod connecting shaft seat always maintains a certain elasticity during normal operation. This elasticity constantly pulls the probe rod body, keeping its end in close contact with the ground.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention designs a monitoring mechanism and a probe rod assembly. As the plow penetrates deeper into the soil, it will drive the probe rod body to rotate downwards. When the probe rod body drives the transmission pin and the rotary transmission coupling to rotate, the encoder body collects the rotation angle signal of the probe rod body in real time. Through the preset angle-tillage depth conversion formula, the real-time soil penetration depth of the plow can be directly calculated. Since the device moves synchronously with the plow, the measurement reference is the plow body. Therefore, it is not affected by factors such as the pitch angle and vibration of the tractor body. The measurement results are stable and accurate, thus ensuring that the depth of the plow penetrating the soil can be more accurate; (2) The present invention The invention designs the mounting frame assembly, and through the design of the arc-shaped adjustment hole and multiple mounting positioning holes, it can change the installation method at different angles, thereby adapting to more types of plows and improving the applicability of the monitoring device; (3) The invention designs multiple limiting holes on the connecting frame of the detection mechanism, and according to the different mounting hole positions, it can meet the monitoring needs of different tillage depth ranges, improve the applicability of the device, and does not require frequent calibration after installation. It has high operational stability. Using the plow as the measurement benchmark, it solves the problem of large measurement error of traditional gyro-based depth sensors. It has the characteristics of strong adaptability, stable structure, and convenient installation and maintenance, and is suitable for high-precision monitoring of tillage depth of reversible plows.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0024] like Figure 1 and Figure 2As shown, this embodiment of a tractor implement working depth monitoring device includes a plow attachment connection assembly 1. The plow attachment connection assembly 1 includes a first connecting hollow column 101. A multi-hole connecting frame rod 102 is fixedly connected to the top center of the first connecting hollow column 101. Rotary connecting assemblies 103 are fixedly connected to both ends of the bottom of the first connecting hollow column 101. A first fixed shaft rod 104 is installed on the top of the multi-hole connecting frame rod 102. A hydraulic tilting drive assembly 105 is rotatably connected to the first fixed shaft rod 104. A rotating connecting sleeve 106 is installed at the output end of the hydraulic tilting drive assembly 105, and the rotating connecting sleeve 106 is sleeved on a second fixed shaft rod 3. A rotating connecting shaft rod 107 is fixedly connected to the center of one side of the first connecting hollow column 101. Before use, the device is installed on agricultural machinery such as a tractor via the multi-hole connecting frame rod 102 and the two rotating connecting assemblies 103 in the plow attachment connection assembly 1. When the hydraulic tilting drive assembly 105 pulls the second connecting hollow column 2, it drives the second fixed shaft 3 to rotate on the rotating connecting shaft 107, causing the entire tilting plow body 4 to tilt over. Multiple plow body components 403 on the other side then contact the ground for operation. The second connecting hollow column 2 is rotatably connected to one side of the plow connecting assembly 1. The second connecting hollow column 2 has a corresponding through hole on the rotating connecting shaft 107. An integral sleeve is fixedly connected to the inner wall of the second connecting hollow column 2 and fits onto the outer wall of the rotating connecting shaft 107, ensuring that the second connecting hollow column 2 can rotate and adjust around the rotating connecting shaft 107 to achieve the tilting of the plow body components 403. The integral sleeve can strengthen the stability of the rotating connection. When rotating, the integral sleeve can withstand more support force, thereby supporting the entire tilting plow body 4. The second fixed shaft 3 is fixedly connected to one end of the second connecting hollow column 2.

[0025] like Figure 1 and Figure 2 As shown, the other end of the second connecting hollow column 2 is fixedly connected to the reversible plow body 4. The reversible plow body 4 includes a plow fixing main rod 401 fixedly connected to one end of the second connecting hollow column 2. Multiple plow extension rods 402 are fixedly connected to the plow fixing main rod 401. The other end of each of the multiple plow extension rods 402 is equipped with a plow body assembly 403. During operation, when the reversible plow enters the soil for cultivation, the multiple plow body assemblies 403 will move downward as the soil depth increases and turn over the soil along the arc surface of the plow body assembly 403. Moreover, the multiple plow body assemblies 403 are not on the same straight line. During operation, they will turn over rows of soil one by one, improving the soil turning efficiency.

[0026] like Figures 1-5As shown, a mounting frame assembly 5 is fixedly connected to the reversible plow body 4. The mounting frame assembly 5 includes two main mounting plates 501 mounted on the reversible plow body 4. Each of the two main mounting plates 501 has an arc-shaped adjustment hole 502, multiple mounting positioning holes 503, and two mounting fixing holes 504. The multiple mounting positioning holes 503 are used to fix the monitoring mechanism 6, and the two mounting fixing holes 504 are used to install the two main mounting plates 501 on the reversible plow body 4. A reinforcing connecting plate 505 is fixedly connected between the two main mounting plates 501. During installation, the entire mounting frame assembly 5 is installed and fixed on the reversible plow body 4 through the two mounting fixing holes 504 and the bolt and nut assembly. At the same time, the reinforcing connecting plate 505 is used to strengthen the stability of the connection between the two main mounting plates 501. The design of the arc-shaped adjustment hole 502 and multiple mounting positioning holes 503 is suitable for adjusting the angle of the monitoring mechanism 6 and installing it in different positions, thus accommodating more different models of plows.

[0027] like Figures 1-8As shown, two main monitoring mechanisms 6 are mounted on the mounting frame assembly 5. The mounting frame assembly 5 is used to connect the reversible plow body 4 and the two main monitoring mechanisms 6. The monitoring mechanism 6 includes a detection mechanism connecting frame 601. Two sets of mounting bolt assemblies 602 are fixedly connected to the bottom of the detection mechanism connecting frame 601, and a fixing rod 603 is fixedly connected to the top of the detection mechanism connecting frame 601. An inner fixing plate 604 and an outer fixing plate 605 are respectively installed on both sides of the detection mechanism connecting frame 601. A transmission pin 606 is provided between the inner fixing plate 604 and the outer fixing plate 605. An encoder support is provided on the other side of the inner fixing plate 604. The encoder bracket 607 houses a rotary transmission coupling 608 installed at one end of the transmission pin 606 inside the encoder bracket 607, and an encoder body 609 is installed at the other end of the rotary transmission coupling 608. During operation, when the reversible plow enters the soil, the plow's soil-entry component moves downward as the soil-entry depth increases, thereby driving the detection rod body 701 to rotate downward. As the detection rod body 701 drives the transmission pin 606 and the rotary transmission coupling 608 to rotate, the encoder body 609 collects the rotation angle signal of the detection rod body 701 in real time. Using a preset angle-tillage depth conversion formula, the plow depth can be directly calculated. The real-time penetration depth of the plow, when facing uneven fields, uses the plow body as a reference and is unaffected by other factors. It only controls the depth between the bottom of the plow body assembly 403 and the contact depth between the end of the probe rod body 701 and the ground, ensuring the stability of this value. The probe penetration distance is thus stable. The probe mechanism connecting frame 601 has circular through holes and grooves corresponding to the fixed round rod 603 and the transmission pin 606. The inner fixing plate 604, outer fixing plate 605, and encoder bracket 607 are all fixed to the probe mechanism connecting frame 601 with bolts and nuts. The encoder body 609 has multiple limiting holes. It is an absolute encoder. The circular through hole ensures that the fixed rod 603 can be inserted. The groove is used to install the transmission pin 606. The limiting holes on the connecting frame 601 of the detection mechanism are divided into upper and lower parts. The upper limiting hole can adjust the lower limit position of the detection rod according to the soil penetration depth range of the plow. At the same time, the lower limiting hole is used to limit the lifting height of the detection rod to avoid interference with other parts of the plow during operation. The absolute encoder can directly output the rotation angle value of the detection rod without additional calibration. The angle resolution is not less than 0.1°, which meets the accuracy requirements for tillage depth measurement.

[0028] like Figure 1 - Figure 8As shown, each of the two main monitoring mechanisms 6 is rotatably connected to a probe rod assembly 7. The probe rod assembly 7 includes a probe rod body 701 fixedly connected to a transmission pin shaft 606. A round rod connecting shaft seat 702 is fixedly connected to the probe rod body 701. A return spring 703 is installed between the round rod connecting shaft seat 702 and the fixed round rod 603. As the plow's soil-penetrating component gradually penetrates the soil, it drives the probe rod body 701 to rotate downwards. At the same time, the return spring 703 is stretched through the round rod connecting shaft seat 702. The return spring 703's elastic force... The probe body 701 is kept in close contact with the ground. The end of the probe body 701 can be fitted with a suitable contact head according to the plow model to ensure the fit with the plow's soil-entry parts and improve the accuracy of angle acquisition. At the same time, depending on the plow or the depth, the fixed round rod 603 can be inserted into different holes to ensure that the return spring 703 between the fixed round rod 603 and the round rod connecting shaft seat 702 always maintains a certain elastic force during normal operation. The elastic force always pulls the probe body 701, keeping its end in close contact with the ground.

[0029] The working principle of this embodiment is as follows: Before use, the plow assembly 1 is installed on agricultural machinery such as tractors via the multi-hole connecting rod 102 and two rotating connecting assemblies 103 in the plow attachment connecting assembly 1. At the same time, one of the mounting bolt assemblies 602 is loosened, allowing the overall monitoring mechanism 6 to rotate around the other mounting bolt assembly 602, thereby adjusting the detection rod assembly 7 to a suitable angle. During operation, when the plow is inserted into the soil, the soil-penetrating parts of the plow (such as the plowshare and plowshare) will move downward as the soil penetration depth increases, thereby driving the detection rod body 701 to rotate downward. Simultaneously, it will be connected via a round rod... The bearing seat 702 stretches the return spring 703, and the elastic force of the return spring 703 keeps the detection rod body 701 in close contact with the ground. When the detection rod body 701 drives the transmission pin 606 and the rotary transmission coupling 608 to rotate, the encoder body 609 collects the rotation angle signal of the detection rod body 701 in real time. Through the preset angle-plowing depth conversion formula, the real-time soil penetration depth of the plow can be directly calculated. Since the whole device moves synchronously with the plow and the measurement reference is the plow body, it is not affected by factors such as the pitch angle and vibration of the tractor body, and the measurement results are stable and accurate. During the flipping process, the hydraulic flipping drive assembly 105 pulls the second connecting hollow column 2, which in turn drives the second fixed shaft 3 to rotate on the rotating connecting shaft 107, causing the entire flipping plow body 4 to flip over. Multiple plow body assemblies 403 on the other side then contact the ground to perform operations. At the same time, the monitoring mechanism 6 and the probe rod assembly 7 on the other side can be adjusted to continue monitoring operations.
