Description

Technical Field

[0001] This application relates to the field of baler technology, and in particular to a bale pressurizing device and a baler. Background Technology

[0002] The baler has a front chamber and a rear chamber, which are locked together by a bale pressurizing device to form a baling chamber. During the bale formation process in the baling chamber, as the weight of the bale increases, the pressure generated within the baling chamber is transmitted to the bale pressurizing device. When the weight of the bale reaches the preset pressure of the bale pressurizing device, the device unlocks, causing the rear chamber to rotate relative to the front chamber and open the baling chamber, thus allowing the bale to be discharged. In related technologies, the preset pressure of the baling pressurizing device is not easily adjustable, making it unable to meet the baling requirements of bales of different weights, resulting in poor versatility.

[0039] See Figure 1An embodiment of this application provides a bale pressurizing device for a baler, comprising a hook locking assembly 3 and a pressure regulating assembly 4. The hook locking assembly 3 is connected to the front chamber 1, and the pressure regulating assembly 4 is connected to the rear chamber 2. When bale processing is required, the hook locking assembly 3 and the pressure regulating assembly 4 connect to lock the front chamber 1 and the rear chamber 2, creating a baling chamber. The pressure regulating assembly 4 includes a pressurizing arm 41, a support rod (not shown), an elastic body 44, a connecting plate 45, multiple spring plates 46, an adjusting screw 47, and a connecting seat 48. One end of the pressurizing arm 41 is movably connected to the rear chamber 2, and the other end of the pressurizing arm 41 is connected to the hook locking assembly 3 to lock the front chamber 1 and the rear chamber 2. One end of the support rod is connected to the pressure arm 41, and the other end of the support rod passes through the pressure arm 41, the elastic body 44, the connecting plate 45, and multiple spring pieces 46 in sequence, and is connected to the connecting seat 48, so that the elastic body 44, the connecting plate 45, and the multiple spring pieces 46 are all located between the pressure arm 41 and the connecting seat 48 and are in abutting state. One end of the elastic body 44 abuts against the pressure arm 41, and the other end abuts against the connecting plate 45. The multiple spring pieces 46 are located between the connecting plate 45 and the connecting seat 48. The threaded section of the adjusting screw 47 passes through the connecting seat 48 and the connecting plate 45 in sequence, and is threadedly connected to the connecting seat 48. The distance between the end of the threaded section of the adjusting screw 47 and the pressure arm 41 is adjustable; the connecting seat 48 is used for movable connection with the rear compartment 2.

[0040] like Figure 1 and Figure 3 As shown, the hook locking assembly 3 and the pressure regulating assembly 4 are connected to lock the front chamber 1 and the rear chamber 2. During the bale formation process in the baling chamber, the pressure arm 41 is compressed by the tension of the hook locking assembly 3, which compresses the elastic body 44 and / or the spring sheet 46 to provide pressure to the bale. During the bale formation process in the baling chamber, due to the compression of the elastic body 44, the distance between the end of the adjusting screw 47 and the pressure arm 41 continuously decreases. When the elastic body 44 reaches its maximum compression, the end of the adjusting screw 47 abuts against the pressure arm 41, at which point the elastic body 44 provides maximum pressure. Therefore, by controlling the distance between the end of the threaded section of the adjusting screw 47 and the pressure arm 41, the compression of the elastic body 44 can be adjusted to achieve the adjustment of the preset pressure of the bale pressing device.

[0041] Furthermore, one end of the support rod is connected to the pressure arm 41, and the other end passes through the elastic body 44, the connecting plate 45, and multiple spring pieces 46 in sequence, and is connected to the connecting seat 48. The preset pressure of the bale pressurizing device can be adjusted by changing the number of spring pieces 46. When the compression of the elastic body 44 reaches its maximum, the number of spring pieces 46 can be adjusted to meet the bale-forming needs of different weights of bales. The preset pressure of the bale pressurizing device can be adjusted by changing the compression of the elastic body 44 and the number of spring pieces 46, demonstrating good versatility. It should be noted that both the elastic body 44 and the spring pieces 46 are made of materials with a certain elastic deformation capacity, such as rubber or silicone.

[0042] Since multiple spring pieces 46 are located between the connecting plate 45 and the connecting seat 48, in order to facilitate the relative fixation of the multiple spring pieces 46, in one embodiment, the pressure regulating assembly 4 further includes a connector 49. The connector 49 is used to fix the multiple spring pieces 46 together. Specifically, the connector 49 includes a connecting screw 491 and a connecting nut 492. The threaded section of the connecting screw 491 passes through the multiple spring pieces 46 and the connecting seat 48 in sequence, and its end is connected to the connecting nut 492. That is, the spring pieces 46 and the connecting seat 48 have through holes corresponding to the connecting screw 491, the threaded section of the connecting screw 491 passes through the through holes, and its end is connected to the connecting nut 492, thereby locking and fixing the multiple spring pieces 46.

[0043] It should be noted that there are multiple connectors 49, which are arranged circumferentially around the spring piece 46, which helps to ensure that the spring piece 46 is subjected to uniform force during compression.

[0044] Furthermore, such as Figure 3 As shown, to simplify the structure of the pressure arm 41 and reduce its weight, in one embodiment, the pressure arm 41 includes a body 411, a mounting plate 412, and a connecting shaft 413. One end of the body 411 has a first connecting hole 4114 for connecting to the rear compartment 2, and the other end of the body 411 has a cavity 4115, within which the mounting plate 412 is located. One end of a support rod is located outside the mounting plate 412 and is detachably connected to it. The other end of the support rod passes sequentially through the mounting plate 412, the elastic body 44, the connecting plate 45, and multiple spring pieces 46, and is connected to a connecting seat 48. The distance between the end of the threaded section of the adjusting screw 47 and the mounting plate 412 is adjustable. By adjusting the distance between the end of the adjusting screw 47 and the mounting plate 412, the compression amount of the elastic body 44 can be adjusted. Furthermore, in order to facilitate the connection between the pressure arm 41 and the hook locking assembly 3, the connecting shaft 413 is located inside the cavity 4115, and its two ends pass through the opposite side walls of the cavity 4115 one by one. The axial direction of the connecting shaft 413 and the axial direction of the support rod are perpendicular to each other. The connecting shaft 413 is used to connect with the hook locking assembly 3.

[0045] Furthermore, such as Figure 3 As shown, in order to facilitate the disassembly of the support rod and the pressure arm 41, the pressure regulating assembly 4 also includes a locking nut 42. The end of the support rod away from the connecting seat 48 is fitted with the locking nut 42. The end face of the locking nut 42 near the elastic body 44 abuts against the pressure arm 41. The other end of the support rod passes through the pressure arm 41, the elastic body 44, the connecting plate 45, and multiple spring pieces 46 in sequence and is connected to the connecting seat 48. When the number of spring pieces 46 needs to be adjusted, the connector 49 can be disassembled first to remove multiple spring pieces 46, increase or decrease the number of spring pieces 46 to the specified number, then loosen the locking nut 42, adjust the distance between the connecting plate 45 and the connecting seat 48 so that multiple spring pieces 46 can be installed between the connecting plate 45 and the connecting seat 48, and lock the multiple spring pieces 46 to the connecting seat 48 through the connector 49, then tighten the locking nut 42, adjust the distance between the connecting seat 48 and the pressure arm 41 to press the multiple spring pieces 46, the connecting plate 45 and the elastic body 44 together.

[0046] Furthermore, in order to facilitate the support rod passing through the mounting plate 412, the elastic body 44, and the multiple spring pieces 46, the gap between the support rod and the through holes opened on the mounting plate 412, the elastic body 44, and the multiple spring pieces 46 is relatively large, and the contact area between the locking nut 42 and the mounting plate 412 is small, making the support rod prone to shaking. Therefore, in one embodiment, the pressure regulating assembly 4 also includes a pressure plate 43, which is sleeved on the support rod and located between the locking nut 42 and the mounting plate 412. The inner diameter of the through hole provided on the pressure plate 43 is slightly smaller than the diameter of the support rod to increase the contact area between the locking nut 42 and the mounting plate 412.

[0047] Furthermore, such as Figure 2 and Figure 3 As shown, to facilitate the connection between the connecting seat 48 and the rear compartment 2, the connecting seat 48 is provided with a second connecting hole 481 for connection with the rear compartment 2. The rear compartment 2 is provided with a pin corresponding to the second connecting hole 481. The pin is inserted into the second connecting hole 481. To prevent the connecting seat 48 from disengaging from the pin, a limiting snap ring is provided at the end of the pin outside the second connecting hole 481.

[0048] Furthermore, such as Figure 3As shown, to simplify the structure of the body 411 and facilitate its processing, in one embodiment, the body 411 includes a first plate 4111, a second plate 4112, and a third plate 4113. The first plate 4111 and the second plate 4112 are fitted together and fixedly connected at one end, while the other ends of the first plate 4111 and the second plate 4112 are spaced apart. The third plate 4113 is located between the first plate 4111 and the second plate 4112, and both ends of the third plate 4113 are connected to the first plate 4111 and the second plate 4112 respectively. The first plate 4111, the second plate 4112, and the third plate 4113 enclose a cavity 4115. The third plate 4113 is used to enhance the overall structural strength of the body 411 and prevent deformation of the body 411 under tension. A first connecting hole 4114 is provided at one end where the first plate 4111 and the second plate 4112 are attached. A hinge shaft corresponding to the first connecting hole 4114 is provided on the rear compartment 2. To increase the contact area between the first connecting hole 4114 and the hinge shaft, such as... Figure 3 As shown, a bushing is inserted into the first connecting hole 4114.

[0049] In one embodiment, the two ends of the connecting shaft 413 pass through the first plate 4111 and the second plate 4112 respectively, and the connecting shaft 413 is detachably connected to the first plate 4111 and the second plate 4112, making it easy to replace the connecting shaft 413. Each end of the connecting shaft 413 corresponding to the end passing through the first plate 4111 and the second plate 4112 is provided with a retaining spring, thereby enabling quick assembly and disassembly of the connecting shaft 413. It should be noted that the connections between the first plate 4111, the second plate 4112, and the third plate 4113 are all fixed by welding.

[0050] Furthermore, such as Figure 1 and Figure 2 As shown, to facilitate the locking and unlocking of the hook locking assembly 3 and the pressure regulating assembly 4, and to facilitate the monitoring of the pressure provided by the pressure regulating assembly 4, the bale pressurizing device of the baler also includes a drive mechanism 5. In one embodiment, the hook locking assembly 3 includes a hook 31 and a density sensor 32; one end of the drive mechanism 5 is rotatably connected to the rear compartment 2, and the other end of the drive mechanism 5 is rotatably connected to the hook 31. The hook 31 has a first strip-shaped hole 3111, and the front compartment 1 has a limiting shaft 11 inserted into the first strip-shaped hole 3111. The hook 31 can rotate around the limiting shaft 11 and can move along the length direction of the first strip-shaped hole 3111. The density sensor 32 is connected to the hook and is used to measure the relative position of the limiting shaft 11 in the first strip-shaped hole 3111. The drive mechanism 5 can drive the hook 31 to rotate and hook onto the connecting shaft 413 of the pressure regulating assembly 4 for locking, or to separate the hook 31 from the connecting shaft 413 for unlocking. The drive mechanism 5 can be a hydraulic cylinder.

[0051] During the bale forming process in the baling chamber, the pressure arm 41 is compressed by the tension of the hook locking assembly 3, which compresses the elastic body 44 and / or the spring sheet 46 to provide pressure to the bale. At this time, due to the compression of the elastic body 44 and the spring sheet 46, the locking hook 31 can move along the length direction of the first strip hole 3111, and the relative position of the limiting shaft 11 within the first strip hole 3111 changes. Since the density sensor 32 is connected to the locking hook 31, the distance between the detection end of the density sensor 32 and the limiting shaft 11 changes, thereby measuring the pressure on the bale. It should be noted that the density sensor 32 is electrically connected to the drive structure and drive mechanism 5 that can drive the rear chamber 2 to rotate relative to the front chamber 1. When the measured pressure on the bale reaches a preset value, the drive mechanism 5 drives the locking hook 31 to rotate and the adjusting assembly to unlock, and the rear chamber 2 rotates away from the front chamber 1 to allow the bale to be discharged.

[0052] Furthermore, after the bales are unloaded, the rear compartment 2 needs to be rotated and reset. In order to facilitate the detection of the reset of the rear compartment 2, the bale pressurizing device also includes a distance sensor 6. The distance sensor 6 is connected to the front compartment 1, and the detection end of the distance sensor 6 is set facing the rear compartment 2. The distance sensor 6 is used to measure the gap between the front compartment 1 and the rear compartment 2.

[0053] Furthermore, to keep the locking hook 31 locked to the pressure arm 41, the hook locking assembly 3 also includes an elastic component 33. One end of the elastic component 33 is connected to the front compartment 1, and the other end of the elastic component 33 is connected to the locking hook 31. When the locking hook 31 and the connecting shaft 413 are in the hooked state, the elastic component 33 is in the stretched state, and the elastic force of the elastic component 33 can make the inner wall of the locking hook 31 abut against the outer wall of the connecting shaft 413. In one embodiment, the elastic component 33 may be a tension spring.

[0054] Furthermore, since both the pressure regulating assembly 4 and the hook locking assembly 3 are assembled from multiple parts, there are internal assembly errors. Therefore, in order for the drive mechanism 5 to rotate the locking hook 31 so that it can engage with the connecting shaft 413, as follows: Figure 1 As shown, the locking hook 31 includes a mounting part 311, a hooking part 312, and a fastener. The mounting part 311 is rotatably connected to the end of the drive mechanism 5 away from the rear compartment 2. The mounting part 311 has a first strip-shaped hole 3111 and a second strip-shaped hole 3112. The second strip-shaped hole 3112 extends toward the pressure arm 41. The fastener is located in the second strip-shaped hole 3112 and is used to fix the mounting part 311 and the hooking part 312. The hooking part 312 is used to hook with the connecting shaft 413. The fastener can be a screw. By adjusting the position of the fastener in the second strip-shaped hole 3112, the relative position of the mounting part 311 and the hooking part 312 can be adjusted, thereby adjusting the overall length of the locking hook 31 so that it can hook with the connecting shaft 413 when the drive mechanism 5 drives the locking hook 31 to rotate.

[0055] This application also provides a baler, including a front chamber 1, a rear chamber 2, and a bale pressurizing device for the baler described above. The front chamber 1 and the rear chamber 2 are locked together by the bale pressurizing device to form a baling chamber.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
