Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a rear-mounted folding side plow for agricultural machinery. Background Technology

[0002] Rotary tillers use the power output from a tractor to drive the cutter shaft to rotate. The blades cut into the soil tangentially, breaking up soil clods and throwing them backward, while simultaneously covering the surface with weeds or stubble, thus achieving integrated tillage, soil breaking, and leveling.

[0003] When a rotary tiller is working, it tills and loosens the soil using a spiral plow and a breaking shovel. The breaking shovel cuts and breaks up the turned soil. However, most current breaking shovels are fixed to a beam, making it impossible to adjust the spacing or number of shovels, as well as their angle and height, resulting in poor soil breaking efficiency and effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rear-mounted folding side plow for agricultural machinery, which solves the problem that the spacing, number, angle, and height of current soil-breaking shovels are difficult to adjust.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A rear-mounted folding side plow for agricultural machinery includes two symmetrical sets of first connecting plates and two symmetrical sets of connecting members located below the two first connecting plates. A first hydraulic cylinder and a second hydraulic cylinder are hinged to both sides of the first connecting plates, with the two first hydraulic cylinders located on the outer sides of the two first connecting plates and the two second hydraulic cylinders located on the inner sides of the two first connecting plates. A first mechanical arm and a second mechanical arm are hinged to the connecting members, with the two first mechanical arms located on the outer sides of the two connecting members and the two second mechanical arms located on the inner sides of the two connecting members. The telescopic ends of the first hydraulic cylinders are pivotally connected to the first mechanical arm, and the telescopic ends of the second hydraulic cylinders are pivotally connected to the second mechanical arm. A third mechanical arm is hinged to the ends of both second mechanical arms, and a third hydraulic cylinder is also hinged to each of the two second mechanical arms. The two third hydraulic cylinders are pivotally connected to the two third mechanical arms. Several sliding sleeves are slidably arranged on the two third mechanical arms, and the sliding sleeves are fixed to the third mechanical arms by positioning components. The proximal ends of the two third mechanical arms are fixed by bolts. Mounting sleeves are fixedly connected to the ends of the first mechanical arms and the sliding sleeves, and a soil-breaking mechanism is mounted on the mounting sleeves.

[0007] Preferably, the connecting component includes a second connecting plate, a U-shaped plate fixed to the second connecting plate, and two side plates fixed to the U-shaped plate. A first robotic arm is hinged to both sides of one of the side plates, and a second robotic arm is hinged to the inner side of the other side plate. A first hinge shaft is fixedly connected to both sides of the first connecting plate. A second hinge shaft is fixedly connected to the first robotic arm. A third and fourth hinge shaft are fixedly connected to the inner side of the second robotic arm. One end of a first hydraulic cylinder is rotatably connected to the outer first hinge shaft, and the telescopic end of the first hydraulic cylinder is rotatably connected to the second hinge shaft. One end of the second hydraulic cylinder is rotatably connected to the inner first hinge shaft, and the telescopic end of the second hydraulic cylinder is rotatably connected to the third hinge shaft. A first hinge seat is fixedly connected to the inner side of the second robotic arm, and the third robotic arm is hinged to the first hinge seat. A second hinge seat is fixedly connected to the third robotic arm near the first hinge seat. One end of the third hydraulic cylinder is rotatably connected to the fourth hinge shaft, and the telescopic end of the third hydraulic cylinder is pivotally connected to the second hinge seat.

[0008] In the above technical solution, when the first hydraulic cylinder is working, it can drive the first robotic arm to swing up and down along the connecting member; when the second hydraulic cylinder is working, it can drive the second robotic arm to swing up and down along the connecting member.

[0009] Preferably, the positioning component includes a first positioning hole on the sliding sleeve and a plurality of second positioning holes on the third robotic arm, and the sliding sleeve is fixed in the first positioning hole and the second positioning holes by positioning screws.

[0010] The above technical solution involves removing the positioning screw to slide the sliding sleeve on the third robotic arm, thereby adjusting the spacing of the earth-breaking mechanism. Once the desired position is reached, the positioning screw is then installed to fix the sliding sleeve on the third robotic arm, thus securing the earth-breaking mechanism.

[0011] Preferably, the soil-breaking mechanism includes a connecting rod, a cover connected to the lower end of the connecting rod, a motor installed inside the cover, and a round shovel connected to the motor shaft of the motor. The connecting rod and the mounting sleeve are both provided with first screw holes, and the connecting rod and the mounting sleeve are connected by bolts.

[0012] The above technical solution involves starting the motor, which drives the circular shovel to rotate, thereby breaking the soil. When the circular shovel is damaged, the connecting rod can be removed from the mounting sleeve, and a new circular shovel can be replaced.

[0013] Preferably, one of the third robotic arms has a slot at its end, and the other third robotic arm has a plate connected to its end. Both the slot and the plate have second screw holes, and the slot and the plate are connected by bolts.

[0014] In the above-described technical solution, when the two third robotic arms separate, the extension of the third hydraulic cylinder pushes the third robotic arm on each side to swing outward, thereby making the two third robotic arms conical and adjusting the angle of the circular shovel to adapt to different soil-breaking environments. When the two third robotic arms are brought together, the slots and plates are fixed together with bolts, allowing for straight-line soil-breaking operations.

[0015] Preferably, both the first connecting plate and the second connecting plate are provided with a number of third screw holes.

[0016] In the above technical solution, both the first connecting plate and the second connecting plate are fixed to the rotary tiller by bolts.

[0017] The beneficial effects of this utility model are:

[0018] The operation of the first hydraulic cylinder drives the first robotic arm to swing up and down, thereby causing the soil-breaking mechanism on the first robotic arm to swing up and down. The operation of the second hydraulic cylinder drives the second robotic arm to swing up and down, thereby causing the third robotic arm and its soil-breaking mechanism to swing up and down. Ultimately, this allows for height adjustment of all soil-breaking mechanisms. The operation of the third hydraulic cylinder causes the third robotic arm to extend outwards, making the two third robotic arms conical, thus adjusting the angle of the soil-breaking mechanism. The position of the soil-breaking mechanism can be adjusted by adjusting the position of the sliding sleeve. Furthermore, the soil-breaking mechanism is bolted to the mounting sleeve for easy replacement. In other words, by adjusting the spacing, number, height, or angle of the soil-breaking mechanisms, different soil-breaking conditions can be accommodated, improving soil-breaking quality and efficiency.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 A rear-mounted folding side plow for agricultural machinery includes two symmetrical sets of first connecting plates 1 and two symmetrical sets of connecting members 2 located below the two first connecting plates 1. The connecting member 2 includes a second connecting plate 201, a U-shaped plate 202 fixed to the second connecting plate, and two side plates 203 fixed to the U-shaped plate. The first connecting plate 1 and the second connecting plate 201 are each provided with several third screw holes. The first connecting plate and the second connecting plate are both fixed to the rotary tiller by bolts.

[0027] One of the side plates 203 has a first robotic arm 5 attached to both sides, and a second robotic arm 6 is hinged to the inside of the other side plate 203. A third robotic arm 7 is hinged to the end of each of the two second robotic arms 6. The two first robotic arms 5 are located on the outside of the two connecting parts 2, and the two second robotic arms 6 are located on the inside of the two connecting parts 2.

[0028] Two first hydraulic cylinders 3 are located on the outer side of the two first connecting plates 1, and two second hydraulic cylinders 4 are located on the inner side of the two first connecting plates 1. First hinge shafts 11 are fixedly connected to both sides of the first connecting plates 1, and second hinge shafts 12 are fixedly connected to the first robotic arm 5. Third hinge shafts 13 and fourth hinge shafts 14 are fixedly connected to the inner side of the second robotic arm 6. One end of the first hydraulic cylinder 3 is rotatably connected to the outer first hinge shaft 11, and the telescopic end of the first hydraulic cylinder 3 is rotatably connected to the second hinge shaft 12. One end of the second hydraulic cylinder 4 is rotatably connected to the inner first hinge shaft 11, and the telescopic end of the second hydraulic cylinder 4 is rotatably connected to the third hinge shaft 13. A first hinge seat 15 is fixedly connected to the inner side of the second robotic arm 6, and the third robotic arm 7 is hinged to the first hinge seat 15. A second hinge seat 16 is fixedly connected to the third robotic arm 7 near the first hinge seat. One end of the third hydraulic cylinder 8 is rotatably connected to the fourth hinge shaft 14, and the telescopic end of the third hydraulic cylinder 8 is pivotally connected to the second hinge seat 16.

[0029] Several sliding sleeves 9 are slidably mounted on the two third robotic arms 7. The sliding sleeves 9 are fixed to the third robotic arms 7 by positioning components. The proximal ends of the two third robotic arms 7 are fixed by bolts. Mounting sleeves 10 are fixedly connected to the end of the first robotic arm 5 and the sliding sleeves 9. The soil-breaking mechanism is mounted on the mounting sleeves 10. The positioning components include a first positioning hole 17 on the sliding sleeve and several second positioning holes on the third robotic arms 7. The sliding sleeves 9 are fixed in the first and second positioning holes by positioning screws 18. The positioning screws 18 are removed to slide the sliding sleeves 9 on the third robotic arms 7, thereby adjusting the spacing of the soil-breaking mechanism. When it reaches the desired position, the positioning screws 18 are reinstalled to fix the sliding sleeves 9 on the third robotic arms 7, thereby fixing the soil-breaking mechanism.

[0030] The soil-breaking mechanism includes a connecting rod 19, a housing 20 connected to the lower end of the connecting rod, a motor installed inside the housing, and a circular shovel 21 driven by the motor shaft. Both the connecting rod 19 and the mounting sleeve 10 have first threaded holes, and the connecting rod 19 and the mounting sleeve 10 are connected by bolts. Starting the motor drives the circular shovel to rotate, thereby breaking the soil. When the circular shovel is damaged, the connecting rod can be removed from the mounting sleeve, and a new circular shovel can be replaced. Additionally, a sealing ring can be installed at the connection between the motor shaft and the housing to prevent soil from entering the motor during the soil-breaking process.

[0031] One of the third robotic arms 7 has a slot 22 at its end, and the other has a plate 23 connected to its end. Both the slot 22 and the plate 23 have second screw holes, and the slots and plates are connected by bolts. When the two third robotic arms separate, the extension of the third hydraulic cylinder pushes the third robotic arm on each side to swing outward, thus making the two third robotic arms conical and adjusting the angle of the circular shovel to adapt to different soil-breaking environments. When the two third robotic arms are closed, the slots and plates are fixed together by bolts, allowing for straight-line soil-breaking operations.

[0032] The working principle of this utility model is as follows: The operation of the first hydraulic cylinder 3 drives the first robotic arm 5 to swing up and down, thereby causing the soil-breaking mechanism on the first robotic arm 5 to swing up and down. The operation of the second hydraulic cylinder 4 drives the second robotic arm 6 to swing up and down, thereby causing the third robotic arm 6 and its soil-breaking mechanism to swing up and down; ultimately, the height of all soil-breaking mechanisms can be adjusted. The operation of the third hydraulic cylinder 8 drives the third robotic arm 7 to extend outward, making the two third robotic arms 7 conical, thereby adjusting the angle of the soil-breaking mechanism. The position of the soil-breaking mechanism can be adjusted by adjusting the position of the sliding sleeve 9. Furthermore, the soil-breaking mechanism is bolted to the mounting sleeve 10 for easy replacement. In other words, by adjusting the spacing, number, height, or angle of the soil-breaking mechanisms, different soil-breaking conditions can be adapted, improving soil-breaking quality and efficiency.
