Description

Technical Field

[0001] This utility model relates to the field of hay bale grabbing technology, and in particular to a mechanical device for picking up hay bales in farmland. Background Technology

[0002] In daily agricultural activities, after harvesting crops, a large amount of straw or stalks are often left over. The conventional process involves using a baler to bundle these scattered straws and stalks before transporting them for processing. While balers demonstrate high efficiency in the baling process, quickly forming bales, the subsequent handling of these bales presents a challenge. Currently, manual handling is commonly used, moving the bales produced by the baler one by one into the collection box. However, the field working environment is already harsh, with dust, uneven ground, and noise and flying fluff during baling. Under such adverse conditions, manual handling is not only slow and inefficient, unable to keep up with the pace of the baler, but also exposes workers to various health risks, eventually leading to physical exhaustion. Therefore, developing a convenient device specifically designed for handling bales in the field to significantly improve efficiency is urgently needed. Summary of the Invention

[0003] This utility model provides a mechanical device for picking up hay bales in farmland to solve the problems in the background art.

[0004] This utility model adopts the following technical solution: a farmland hay bale picking machine includes a mounting frame installed on a tractor. A lifting device is provided on one side of the mounting frame, and a placement box is mounted on the lifting device. A rotating assembly is provided on the other side of the mounting frame, and a connecting assembly is mounted on the rotating assembly. The rotating assembly allows the connecting assembly to rotate. A driving assembly is installed inside the connecting assembly, and two symmetrically arranged grippers are also mounted on the connecting assembly. Both grippers are connected to the driving assembly, allowing the two grippers to perform a clamping action on the connecting assembly. This solves the problem of manual handling of hay bales in the field in the prior art. This application not only improves the efficiency of hay bale handling in the field but also reduces the potential health risks to workers caused by poor field conditions.

[0005] Furthermore, the rotating assembly includes a drive device, a mounting frame, and a drive sprocket. The drive device is mounted on a mounting plate and is located on one side of the lifting device. The drive device has a mounting frame for mounting the connecting assembly. The drive device also has a drive sprocket, one end of which is connected to the working end of the drive device, and the other end of which is connected to the connecting assembly mounted on the mounting frame. The rotating assembly is used to mount the connecting assembly and drive the connecting assembly to rotate.

[0006] Furthermore, the connecting assembly includes a connecting arm, a fixed connecting plate, and a drive frame. One end of the connecting arm is rotatably mounted in the placement frame, and the other end of the connecting arm is connected to the drive sprocket. The fixed connecting plate is disposed on the other end of the connecting arm, and the drive frame is mounted on the fixed connecting plate. The drive frame has a space for placing the drive assembly. The connecting assembly is used to place the drive assembly and also to mount two grippers. Under the operation of the rotating assembly, the connecting assembly can drive the two grippers to rotate, causing the two grippers to move between the field bale and the placement box.

[0007] Furthermore, the drive assembly includes a drive motor, a drive rod, a drive gear set, a transmission gear set, and a belt. The drive motor is located at the center of the drive frame. The drive gear assemblies are in pairs, with each drive gear having a transmission rod mounted on it. The two drive gears mesh with each other and are mounted at the center of the drive frame via the transmission rods. One of the drive gears has a transmission rod connected to the output end of the drive motor. There are two sets of transmission gear assemblies, symmetrically arranged on both sides of the drive frame. Each set contains two transmission gears, one of which is connected to a drive gear via a belt. The other transmission gear in each set is mounted on a gripper. The drive assembly drives the two grippers on the drive frame to rotate, enabling them to clamp the bale of straw.

[0008] Furthermore, each of the grippers is equipped with a rotating connecting rod, and each gripper is rotatably mounted on one side of the drive frame via the rotating connecting rod. The other transmission gear in each transmission gear set is mounted on a rotating connecting rod. The grippers are used to grip bales of straw.

[0009] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0010] This application designs a bale-grabbing device for moving pre-baled bales in the field. The device is applied to a tractor, a common technology, and moves the bale across the field using the tractor. When the device approaches a bale, a drive assembly causes the grippers to pick it up. A rotating assembly then drives a connecting assembly, which in turn moves the two grippers to move the bale into a placement box. A worker can then stack the bales neatly inside the placement box. Furthermore, this application places the placement box on a lifting device, and the box is filled with… After the bales are bled, the tractor will move the placement box to the hay collection box, which is usually a large truck body used to transport the bales. Therefore, in this application, a lifting device can be used to move the placement box up and down, so that the placement box can be moved to the same height as the hay collection box. This makes it easier for workers to move the bales from the placement box to the hay collection box. This method can solve the problem of manually handling bales in the field in the existing technology, which not only improves the efficiency of handling bales in the field, but also reduces the problem of the poor field environment that may cause harm to the health of workers.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0020] Reference Figures 1-5 This utility model provides a farmland hay bale picking machine, including a mounting frame 1 installed on a tractor. A lifting device 2 is provided on one side of the mounting frame 1, and a placement box 3 is installed on the lifting device 2. A rotating component 4 is provided on the other side of the mounting frame 1, and a connecting component 5 is installed on the rotating component 4. The connecting component 5 can be rotated by the rotating component 4. A driving component 6 is installed inside the connecting component 5, and two symmetrically arranged grippers 7 are also installed on the connecting component 5. Both grippers 7 are connected to the driving component 6, and the driving component 6 can cause the two grippers 7 to perform a clamping action on the connecting component 5.

[0021] This application designs a bale-grabbing device for moving pre-baled bales in the field. This device is applied to a tractor in the prior art. Using the tractor as a carrier, it moves in the field. When it reaches the vicinity of a bale, the drive assembly 6 opens the gripper 7, placing the bale within the gripper 7. The drive assembly 6 then causes the gripper 7 to grasp the bale. The rotating assembly 4 drives the connecting assembly 5 to rotate, allowing the connecting assembly 5 to move the two grippers 7 into a placement box 3. A worker can be positioned inside the placement box 3 to stack the bales neatly. Furthermore, in this application, the placement box 3 is designed with a lifting mechanism... After the bales are filled in the placement box 3 on the lifting device 2, the tractor will move the placement box 3 to the hay collection box, which is usually a large truck box used to transport these bales. Therefore, in this application, the lifting device 2 can be used to move the placement box 3 up and down, so that the placement box 3 can be moved to the same height as the hay collection box. This makes it easier for workers to move the bales in the placement box 3 to the hay collection box. This method can solve the problem of manually handling bales in the field in the prior art, which not only improves the efficiency of handling bales in the field, but also reduces the problem of the poor field environment that may cause harm to the health of workers.

[0022] Preferably, the rotating assembly 4 includes a driving device 41, a placement frame 42, and a driving sprocket 43. The driving device 41 is mounted on the mounting plate frame 1 and is located on one side of the lifting device 2. The driving device 41 is provided with a placement frame 42, which is used to install a connecting assembly 5. The driving device 41 is provided with a driving sprocket 43, one end of which is connected to the working end of the driving device 41, and the other end of which is connected to the connecting assembly 5 mounted on the placement frame 42.

[0023] In this application, the placement frame 42 is used to install the connecting component 5, and the connecting component 5 can rotate on the placement frame 42. Through the connection of the drive sprocket 43 to the connecting component 5, the connecting component 5 can be driven to rotate on the placement frame 42 by the drive sprocket 43 when the drive device 41 is running.

[0024] The drive device 41 uses a hydraulic motor, and one end of the drive sprocket 43 is fixedly mounted on its output shaft via a key connection to ensure stable power transmission. The connection between the other end of the drive sprocket 43 and the connecting arm 51 is designed as a specially made bushing structure. This bushing is tightly nested in the end of the connecting arm 51 near the placement frame 42, and the bushing and the connecting arm 51 are reinforced and fixed together by welding, making them a whole. On the outer circumferential surface of the bushing, multiple toothed grooves that are adapted to the drive sprocket 43 are evenly machined along the circumferential direction. The chain on the drive sprocket 43 is wrapped around these toothed grooves. When the hydraulic motor is running, it drives the drive sprocket 43 to rotate. Through the meshing action of the chain and the toothed grooves, the connecting arm 51 is driven to rotate smoothly around the axis of the bushing on the placement frame 42. Meanwhile, a high-precision bearing is installed at the connection between the connecting arm 51 and the placement frame 42 to reduce rotational friction, ensure the rotational flexibility and stability of the connecting arm 51, and ensure that it can accurately move the gripper 7 to the position of the straw bale in the field.

[0025] Preferably, the connecting assembly 5 includes a connecting arm 51, a fixed connecting plate 52, and a drive frame 53. One end of the connecting arm 51 is rotatably mounted in the placement frame 42, and the connecting arm 51 is connected to the other end of the drive sprocket 43. The fixed connecting plate 52 is disposed on the other end of the connecting arm 51, and the drive frame 53 is mounted on the fixed connecting plate 52. The drive frame 53 has a space for placing the drive assembly 6.

[0026] In this application, the connecting arm 51 is used to be mounted on the placement frame 42 and connected to the drive sprocket 43. When the drive device 41 is running, the connecting arm 51 can be rotated on the placement frame 42 by the drive sprocket 43. The connecting arm 51 will be tilted according to the height of the tractor. The connecting arm 51 can make the position of the gripper 7 correspond to the position of the hay bale in the field. The drive frame 53 is used to mount the gripper 7 and the drive assembly 6.

[0027] Preferably, the drive assembly 6 includes a drive motor 61, a drive rod, a drive gear set 62, a transmission gear set 63, and a belt 65. The drive motor 61 is located at the middle position above the drive frame 53. The drive gear sets 62 are in pairs, and each drive gear is equipped with a transmission rod 64. The two drive gears mesh with each other and are installed at the middle position inside the drive frame 53 through the transmission rod 64. The transmission rod 64 on one of the drive gears is connected to the output end of the drive motor 61. There are two sets of transmission gear sets 63, which are symmetrically arranged on both sides inside the drive frame 53. Each set of transmission gear sets 63 has two transmission gears. One of the transmission gears in each set of transmission gear sets 63 is connected to a drive gear through a belt 65. The other transmission gear in each set of transmission gear sets 63 is mounted on a gripper 7.

[0028] In this application, the drive motor 61 is used to drive the transmission rod 64 provided on the drive gear in the drive gear set 62 to rotate. In this way, the drive gear set 62 will rotate. When the drive gear set 62 rotates, it will drive the two sets of transmission gear sets 63 to rotate through the two belts 65 respectively. Since the drive gear set 62 transmits power through the meshing of the two drive gears, the drive gear set 62 will cause the two sets of transmission gear sets 63 to rotate in opposite directions. In this way, when the two sets of transmission gear sets 63 drive the two grippers 7 to rotate, the two grippers 7 will move relative to each other.

[0029] In this application, the connection between the drive gear set 62 and the belt 65 is optimized: On the side of each drive gear in the drive gear set 62, a trapezoidal tooth groove is provided along the circumference, matching the inner surface of the belt 65. The inner side of the belt 65 is also machined with corresponding trapezoidal teeth. Through the meshing of the teeth, reliable power transmission from the drive gear set 62 to the belt 65 is achieved. Simultaneously, at the connection end between the belt 65 and the transmission gear set 63, a hub with a groove is designed for each transmission gear. The belt 65 passes around this hub, and the shape of the groove matches the cross-sectional shape of the belt 65. This ensures that the belt 65 stably drives the transmission gear to rotate while preventing the belt 65 from slipping off during operation.

[0030] Preferably, each of the grippers 7 is provided with a rotating connecting rod 71, and each gripper 7 is rotatably mounted on one side of the drive frame 53 via the rotating connecting rod 71. In each set of transmission gears 63, another transmission gear is provided on a rotating connecting rod 71.

[0031] In this application, two grippers 7 are symmetrically arranged on the drive frame 53. The grippers 7 are connected to the drive frame 53 through a rotating connecting rod 71. One of the transmission gears in the transmission gear set 63 is installed on the rotating connecting rod 71. In this way, when each transmission gear set 63 is driven by the drive gear set 62, the grippers 7 can rotate on the drive frame 53. When the two grippers 7 rotate at the same time, they will move relative to each other.

[0032] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
