Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular, to an electronically controlled clutch mechanism. Furthermore, this utility model also relates to a square baler including the aforementioned electronically controlled clutch mechanism. Background Technology

[0002] With the rapid development of agricultural mechanization and large-scale operations, balers have become crucial equipment in the harvesting of straw and forage. Existing large square balers have relatively simple feeding mechanisms, lacking refinement and intelligence in their design, resulting in highly unstable feeding volumes. This instability directly affects the quality and specifications of the bales, leading to inconsistent bale density and varying sizes. On the one hand, uneven bale density can result in wasted space during transportation and storage, increasing logistics costs; on the other hand, inconsistent bale sizes reduce the convenience of subsequent processing and utilization, impacting market competitiveness.

[0003] Furthermore, the baler's production efficiency is significantly limited by the inadequate performance of the feeding mechanism. In actual operation, the instability and inefficiency of the feeding mechanism often lead to problems such as decreased bale regularity, insufficient bale density, and inconsistent overall quality. These problems not only increase operating costs but also reduce equipment reliability, affecting user experience and economic benefits. Especially when dealing with straw or forage of different moisture levels and varieties, the existing feeding mechanism has poor adaptability and is difficult to adjust flexibly according to material characteristics, further exacerbating the aforementioned problems.

[0006] A pressure feedback mechanism is installed in the pre-compression channel to detect the accumulation pressure of the forage in the pre-compression channel;

[0007] A clutch assembly is disposed in the feeding mechanism and is used to control the transmission engagement between the feeding mechanism and the driving device by an external drive.

[0008] A stop mechanism, disposed on the frame, is used to engage or disengage from the clutch assembly under external drive;

[0009] The actuating mechanism is electrically connected to the pressure feedback mechanism, and the output end of the actuating mechanism is connected to the stop mechanism. It is used to actuate the stop mechanism when the pressure value fed back by the pressure feedback mechanism reaches a set value.

[0010] As a further improvement to the above technical solution, the electronically controlled clutch mechanism also includes a braking device, which is disposed on the drive shaft and is used to dampen the engagement between the stop mechanism and the clutch assembly.

[0011] As a further improvement to the above technical solution, the stopping mechanism includes a V-shaped stopping rod, which includes a first mating rod and a second mating rod. The first mating rod and the second mating rod are rotatably connected to the frame at their connection positions. The outer end of the first mating rod is used to engage with the clutch assembly. The stopping rod is also used to be driven to rotate by a pushing mechanism to disengage the first mating rod from the clutch assembly. The clutch assembly includes a cam surface disposed on the feeding mechanism. The cam surface is used to abut against the end of the second mating rod when rotating to a preset circumferential position range, thereby driving the stopping rod to rotate and reset.

[0012] As a further improvement to the above technical solution, the pressure feedback mechanism includes a pressure detection unit disposed in the pre-pressure channel.

[0013] As a further improvement to the above technical solution, the pressure feedback mechanism includes a pressure plate disposed in the pre-compression channel, and the pressure detection unit is disposed in the pressure plate; the pushing mechanism includes a control rod, an adjusting rod, an electric push rod, a mounting base, and an elastic pressure application component; the mounting base is hinged to the frame, the two ends of the control rod are respectively hinged to the frame and the pressure plate and the control rod passes through the mounting base, the two ends of the adjusting rod are respectively hinged to the stop mechanism and the control rod, the fixed end of the electric push rod is hinged to the frame, and the output end of the electric push rod is rotatably connected to the middle of the first cooperating rod through the elastic pressure application component. The elastic pressure application component is used to apply force to the control rod so that when the pressure plate in the pre-compression channel reaches a preset pressure, it drives the control rod to swing, which in turn drives the stop mechanism to disengage from the clutch component via the adjusting rod. The electric push rod is used to adjust the compression or extension of the elastic pressure application component according to the set pressure value to adjust the preset pressure of the pressure plate movement.

[0014] As a further improvement to the above technical solution, the elastic pressure assembly includes a rotating handle rotatably connected to the mounting base, the first end of the rotating handle being hinged to the output end of the electric push rod, and an elastic element being disposed between the second end of the rotating handle and the control rod.

[0015] As a further improvement to the above technical solution, the pressure detection unit is located at the bottom of the pre-pressure channel; the pushing mechanism includes an electric push rod mounted on the frame, and the output end of the electric push rod is rotatably connected to the middle of the first mating rod.

[0016] As a further improvement to the above technical solution, the clutch assembly includes a clutch lever, an elastic auxiliary component, and a mating structure. The mating structure is connected to the drive device. The elastic auxiliary component is connected to both the mating structure and the clutch lever. The elastic auxiliary component is used to store energy when the clutch lever engages with the stop mechanism and to disengage the mating structure from the feeding mechanism. It is also used to release the stored energy when the stop mechanism disengages from the clutch lever to drive the mating structure to engage with the feeding mechanism.

[0017] As a further improvement to the above technical solution, the driving device includes a sprocket disposed on the driving shaft, and the feeding mechanism includes a rotating arm disposed on the driving shaft, an arc-shaped swing arm rotatably connected to the end of the rotating arm, and a feeding fork disposed at the end of the arc-shaped swing arm. An arc-shaped groove is provided on the arc-shaped swing arm, and a sliding rod passing through the arc-shaped groove is provided on the frame. The rotating arm is used to be driven by the sprocket to rotate, causing the feeding fork of the arc-shaped swing arm to be inserted from the bottom of the pre-compression channel and swing along the pre-compression channel to the top before retracting to the reset position.

[0018] According to another aspect of the present invention, a square bundling machine is also provided, which includes the above-mentioned electronically controlled clutch mechanism.

[0019] This utility model has the following beneficial effects:

[0020] This electronically controlled clutch mechanism detects the accumulated pressure of the straw in the pre-compression channel through a pressure feedback mechanism and feeds it back to the pushing mechanism. When the preset pressure value is reached, the pushing mechanism drives the stop mechanism to disengage from the clutch assembly. After the clutch assembly disengages from the stop mechanism, it engages with the feeding mechanism, causing the drive device to drive the feeding mechanism through the clutch assembly to perform one feeding action. After the feeding mechanism performs one feeding action, it resets and simultaneously drives the stop mechanism to reset and engage with the clutch assembly again. This clutch mechanism controls the feeding mechanism's action based on the pressure value detected by the pressure feedback mechanism, ensuring that it performs the feeding action after reaching the set pressure. The pressure value can be matched and set according to different humidity levels and different varieties of straw or forage, with higher precision. This effectively improves the pre-compression effect of straw and the uniformity of individual straw pieces, which is more conducive to bale formation and quality stability. It greatly improves the adaptability and intelligence of the square baler and reduces manual operation.

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0030] Figure 1 This is a schematic diagram of the structure of an embodiment of the present utility model; Figure 2 This is a schematic diagram of another embodiment of the present invention; Figure 3 This is a partial structural schematic diagram of the pushing mechanism of a preferred embodiment of the present invention; Figure 4 This is a reference diagram showing the usage state of the braking device according to a preferred embodiment of the present invention.

[0031] like Figures 1 to 4As shown, the electronically controlled clutch mechanism of this embodiment is applied to the pre-compression system of a square baler. The pre-compression system includes a frame, a drive shaft mounted on the frame, a drive device mounted on the drive shaft, and a feeding mechanism fixedly mounted on the drive shaft. The frame has a pre-compression channel 8. The drive device is used to drive the feeding mechanism to move and push the straw in the pre-compression channel 8. The electronically controlled clutch mechanism includes:

[0032] A pressure feedback mechanism is installed in the pre-compression channel 8 to detect the accumulation pressure of the forage in the pre-compression channel 8;

[0033] The clutch assembly is located in the feeding mechanism and is used for the transmission engagement between the feeding mechanism and the drive shaft, which is controlled by an external drive.

[0034] The stop mechanism, mounted on the frame, is used to engage or disengage from the clutch assembly under external drive.

[0035] The actuating mechanism 1 is electrically connected to the pressure feedback mechanism. The output end of the actuating mechanism 1 is connected to the stop mechanism and is used to actuate the stop mechanism when the pressure value fed back by the pressure feedback mechanism reaches the set value.

[0036] The feeding mechanism is based on the feeding mechanism of the existing square bundling machine. Specifically, the driving device includes a sprocket 5 on the drive shaft, which drives the equipment to rotate. The feeding mechanism includes a rotating arm 6 on the drive shaft, an arc-shaped swing arm 7 rotatably connected to the end of the rotating arm 6, and a feeding fork 14 on the end of the arc-shaped swing arm 7. The arc-shaped swing arm 7 has an arc-shaped groove, and a slide rod passing through the arc-shaped groove is provided on the frame. The rotating arm 6 is driven by the sprocket 5 to rotate and drive the feeding fork 14 of the arc-shaped swing arm 7 to insert from the bottom of the pre-compression channel 8 and swing along the pre-compression channel 8 to the top before retracting to the reset position. The rotating arm 6 and the arc-shaped swing arm 7 are symmetrically distributed at both ends of the drive shaft. The rotation of the rotating arm 6 on one side drives the rotation of the rotating arm 6 on the other side to rotate synchronously.

[0037] Understandably, this electronically controlled clutch mechanism detects the accumulated pressure of the straw in the pre-compression channel 8 through a pressure feedback mechanism and feeds it back to the push mechanism 1. When the preset pressure value is reached, the push mechanism 1 pushes the stop mechanism to disengage from the clutch assembly. After the clutch assembly disengages from the stop mechanism, it engages with the feeding mechanism, causing the drive device to engage with the feeding mechanism via the clutch assembly. This drives the feeding mechanism to perform one feeding action and then resets, simultaneously driving the stop mechanism to reset and engage with the clutch assembly again. This clutch mechanism controls the feeding mechanism's action based on the pressure value detected by the pressure feedback mechanism, ensuring that it performs the feeding action after reaching the set pressure. It can match and set pressure values ​​according to different humidity levels and different varieties of straw or forage, with higher precision. This effectively improves the pre-compression effect of straw and the uniformity of individual straw pieces, making it more conducive to bale formation and quality stability, improving the adaptability and intelligence of the square baler, and reducing manual operation.

[0038] Furthermore, the electronically controlled clutch mechanism also includes a braking device 17, which is disposed on the drive shaft and is used to dampen the engagement between the stop mechanism and the clutch assembly. By providing the braking device 17, damping is continuously provided during the engagement of the drive stop mechanism and the clutch assembly to reduce impact, making the operation more stable. It also prevents the clutch assembly and stop mechanism from slipping out or sliding during the reset process, which would cause the reset failure and cause the feeding mechanism to perform the feeding action again, thus further ensuring the bale forming and quality stability. The braking device 17 preferably adopts a brake of the prior art.

[0039] In some embodiments, the stopping mechanism includes a V-shaped stop rod 4. The stop rod 4 includes a first mating rod 401 and a second mating rod 402. The connection position of the first mating rod 401 and the second mating rod 402 is rotatably connected to the frame. The outer end of the first mating rod 401 is used to engage with a clutch assembly. The stop rod 4 is also used to be driven to rotate by the pushing mechanism 1 to disengage the first mating rod 401 from the clutch assembly. The clutch assembly includes a cam surface 601 disposed on the rotating arm 6 of the feeding mechanism. The cam surface 601 is used to abut against the end of the second mating rod 402 when rotating to a preset circumferential position range, thereby driving the stop rod 4 to rotate and reset. Specifically, the first mating rod 401 and the second mating rod 402 are arranged at a preset angle. In this embodiment, an acute angle is used as an example. The length of the first mating rod 401 is... The length of the first engaging rod 401 is greater than that of the second engaging rod 402. The pushing mechanism 1 acts on the middle position of the first engaging rod 401. The end of the first engaging rod 401 engages with the clutch assembly. When the pushing mechanism 1 acts on the first engaging rod 402, it drives the stop rod 4 to swing, causing the first engaging rod 401 to disengage from the clutch assembly. The second engaging rod 402 swings to the circumferential rotation range of the cam surface 601. At this time, the cam surface 601 does not engage with it. After the cam surface 601 moves for nearly one revolution with the feeding mechanism, the cam surface 601 abuts against the end of the second engaging rod 402. As the cam surface 601 rotates, it drives the second engaging rod 402 to move, which in turn drives the stop rod 4 to swing, causing the first engaging rod 401 to reset. It continues to rotate until the clutch assembly engages with it again, making the overall structure simple, reasonable and space-saving.

[0040] Understandably, a roller is installed at the end of the second mating rod to reduce friction when mating with the cam surface and avoid jamming.

[0041] In some embodiments, the pressure feedback mechanism includes a pressure detection unit disposed in the pre-pressure channel 8. The pressure detection unit may be a pressure sensor, strain gauge, or other prior art device.

[0042] In some embodiments, reference Figure 1 The pressure detection unit is located at the bottom of the pre-pressure channel 8; the pushing mechanism 1 includes an electric push rod 10 mounted on the frame, the output end of which is rotatably connected to the middle of the first cooperating rod. When the pressure value fed back by the pressure detection unit reaches the set pressure value, the electric push rod 10 moves to drive the stop mechanism to move the clutch assembly, and the drive device and the feeding mechanism work together to perform the feeding action. The electric clutch mechanism in this embodiment has a simplified structure. The pressure is detected by the pressure detection unit at the bottom of the pre-pressure channel 8. Only a matching pressure value needs to be set for different working conditions. When the pressure reaches the pressure value, the electric clutch mechanism works to make the feeding mechanism perform the feeding action. It has strong working stability and strong adaptability.

[0043] In some embodiments, reference Figure 2Alternatively, the pressure feedback mechanism may include a pressure plate 9 disposed in the pre-compression channel 8, and a pressure detection unit disposed in the pressure plate 9; the pushing mechanism 1 may include a control rod 2, an adjusting rod 3, an electric push rod 10, a mounting base 15, and an elastic pressure application component; the mounting base 15 is hinged to the frame, the two ends of the control rod 2 are respectively hinged to the frame and the pressure plate 9 and the control rod 2 passes through the mounting base 15, the two ends of the adjusting rod 3 are respectively hinged to the stop mechanism and the control rod 2, the fixed end of the electric push rod 10 is hinged to the frame, and the output end of the electric push rod 10 is rotatably connected to the middle of the first cooperating rod through the elastic pressure application component. The elastic pressure application component is used to apply force to the control rod 2 so that when the pressure plate 9 reaches the preset pressure in the pre-compression channel 8, it drives the control rod 2 to swing, which in turn drives the stop mechanism to disengage from the clutch component via the adjusting rod 3. The electric push rod 10 is used to adjust the pressure value according to the set pressure value. The compression or extension of the elastic pressure component is adjusted to regulate the preset pressure of the pressure plate 9. It can be understood that when the control rod 2 swings, its end moves along the path of the pre-pressure channel 8. Based on this, the control rod 2 swings based on the rotation of the mounting base 15 and slides axially along the mounting base 15 to ensure the bottom fits with the pre-pressure channel 8. In this embodiment, the elastic force of the elastic pressure component applies a load to the control rod 2. When the pressure of the straw in the pre-pressure channel 8 is higher than the force exerted by the elastic pressure component on the control rod 2, the control rod 2 can swing, thereby actuating the stop mechanism. This method has lower energy consumption than the previous embodiment. The pressure that triggers the action of the pressure plate 9 can be adjusted by regulating the compression or extension of the elastic pressure component through the electric push rod 10. That is, the electric push rod 10 only needs to adjust the compression or extension of the elastic pressure component according to the set pressure value, resulting in low energy consumption and strong adaptability.

[0044] The elastic pressure assembly includes a rotating handle 12 rotatably connected to the mounting base 15. The first end of the rotating handle 12 is hinged to the output end of the electric push rod 10. An elastic element 13, which is a spring, is provided between the second end of the rotating handle 12 and the control rod 2. The electric push rod 10 drives the first end of the rotating handle 12 to move, causing the elastic element 13 between the second end of the rotating handle 12 and the control rod 2 to compress, thereby acting on the control rod 2. The end of the control rod 2 has a limiting structure 11 to restrict its movement towards the feed end of the pre-compression channel 8. When the pressure of the straw accumulation in the pre-compression channel 8 reaches the set value, it pushes the pressure plate 9 to drive the control rod 2 to overcome the force of the elastic element 13 and make the control rod 2 swing. The structure is simple, the implementation cost is low, and the maintenance is convenient.

[0045] In some embodiments, the clutch assembly includes a clutch lever 16, an elastic auxiliary component, and a mating structure. The mating structure is connected to the drive device, and the elastic auxiliary component is connected to both the mating structure and the clutch lever 16. The elastic auxiliary component is used to store energy when the clutch lever 16 engages with the stop mechanism and to disengage the mating structure from the feeding mechanism. It is also used to release the stored energy when the stop mechanism disengages from the clutch lever 16 to drive the mating structure to engage with the feeding mechanism. The end of the clutch lever 16 is provided in the mating groove so that the end of the first mating rod can be embedded, resulting in a tight and stable fit. When the clutch lever 16 engages with the first mating rod, the elastic auxiliary component is in an energy-storing state, i.e., a stretched or compressed state. After the first mating rod disengages from the clutch lever 16, the elastic auxiliary component releases, driving the mating structure to engage with the drive device, thereby enabling the drive device to be connected to the feeding mechanism for transmission and performing the feeding action. After the cam surface drives the second mating rod to reset the stop lever 4, the clutch assembly continues to rotate circumferentially until the clutch lever 16 engages with the first mating rod again. The elastic auxiliary component stores energy, and the mating structure disengages from the drive device.
