Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary tiller technology, specifically a folding disc plow. 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] However, the current rotary tillers have the following problems: (1) When working, the tilling shaft drives the spirally distributed tilling blades to rotate, thereby tilling the land. However, it is difficult to break the soil on both sides of the tilling shaft by tilling blades alone. If the soil texture is hard, the tilling effect is not good. (2) If a soil breaking shovel is added to both sides of the rotary tiller, the soil breaking shovel cannot be adjusted in height and angle, so the depth and angle of soil breaking cannot be adjusted. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a folding disc plow to solve the problem mentioned in the background art of the difficulty in adjusting the soil-breaking depth and angle of the soil-breaking shovel.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A folding disc plow includes a first mounting plate and a second mounting plate. A first hydraulic cylinder is hinged to the first mounting plate, and a hinge seat is fixed to the second mounting plate. A deflection plate is hinged to the hinge seat, and a first connecting plate is fixedly connected to the top of the deflection plate. The telescopic end of the first hydraulic cylinder is pivotally connected to the first connecting plate. A bushing is fixedly connected to the end of the deflection plate away from the hinge seat. A rotating shaft is rotatably connected to the bushing via a rotary bearing. A housing is connected to the lower end of the rotating shaft. A motor is housed inside the housing, and the motor is connected to a drive shaft via a coupling. The drive shaft extends out of the housing, and a first flange is fixedly connected to the extending end. A circular shovel is bolted to the first flange. The deflection plate is also provided with a hydraulic adjustment mechanism for adjusting the angle of the shovel.
[0007] Preferably, the hinge seat includes a base plate, two side plates fixedly connected to one side of the base plate, and a reinforcing plate fixedly connected to the base plate and located outside the two side plates. The reinforcing plate is connected to the side plate on its respective side, and the deflection plate is hinged between the two side plates through a hinge shaft.
[0008] The above technical solution, by connecting the bottom plate and the side plate with a reinforcing plate, plays a role in improving the structural strength.
[0009] Preferably, the surface of the soil-breaking shovel is spherical, and its outer periphery is serrated.
[0010] With the above technical solution, the outer periphery of the soil-breaking shovel is serrated, which can tear the soil. The torn soil will spread outward along the spherical surface of the soil-breaking shovel to prevent soil accumulation from affecting the operation of the soil-breaking shovel.
[0011] Preferably, both the first mounting plate and the second mounting plate have mounting holes.
[0012] The above technical solution involves fixing the first mounting plate and the second mounting plate onto the rotary tiller using bolts.
[0013] Preferably, the hydraulic adjustment mechanism includes an extension plate vertically connected to one side of the deflection plate, and a second connecting plate fixedly connected to the upper end of the rotating shaft and facing the extension plate. A second hydraulic cylinder is pivotally connected to the extension plate, and the telescopic end of the second hydraulic cylinder is pivotally connected to the second connecting plate.
[0014] With the above technical solution, when it is necessary to adjust the soil breaking angle, the second hydraulic cylinder is controlled to work, and the second hydraulic cylinder will drive the rotating shaft to rotate at a certain angle, thereby fine-tuning the angle of the soil breaking shovel.
[0015] Preferably, the upper part of the rotating shaft is provided with a cylindrical groove, and a pipe is fixedly connected in the cylindrical groove. The upper end of the pipe is connected to a water inlet pipe through a rotary sealing joint. A second flange is fixedly connected to the water inlet pipe. A water spray pipe is connected to the lower part of the rotating shaft. The water spray pipe is connected to the pipe, and a nozzle is connected to the side of the water spray pipe facing the shovel.
[0016] The above technical solution connects the second flange to the water tank on the rotary tiller, supplies water to the pipeline through the water tank, and sprays it onto the soil-breaking shovel through the nozzle, thereby delivering water to the soil, reducing soil hardness, and facilitating soil breaking.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] (1) Install two sets of disc plows as described in this utility model on the rotary tiller. When tilling the land, the soil can be torn apart by the two soil-breaking shovels, thereby improving the efficiency and quality of tilling.
[0019] (2) The first hydraulic cylinder can drive the deflector plate to swing up and down, thereby adjusting the soil breaking depth of the soil breaking shovel. The angle of the soil breaking shovel can be finely adjusted through the hydraulic adjustment mechanism, thereby adjusting the soil breaking angle and improving the convenience of soil breaking.

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.
[0025] Example 1
[0026] Please see Figures 1-2 A folding disc plow includes a first mounting plate 1 and a second mounting plate 2. Both the first mounting plate 1 and the second mounting plate 2 are provided with mounting holes. The first mounting plate 1 and the second mounting plate 2 are fixed to the rotary tiller by bolts. A first hydraulic cylinder 3 is hinged to the first mounting plate 1. A hinge seat 4 is fixed to the second mounting plate 2. A deflection plate 5 is hinged to the hinge seat 4. A first connecting plate 6 is fixedly connected to the top of the deflection plate 5.

The drive shaft passes through the housing 9 and a first flange 10 is fixedly connected to the end of the drive shaft. A circular shovel 11 is bolted to the first flange 10. The drive shaft is rotatably connected to the housing through a rotary bearing, and a sealing ring is provided at the contact point between the drive shaft and the housing to prevent soil from entering the housing.
[0027] In this embodiment, the hinge base 4 includes a base plate 401, two side plates 402 fixedly connected to one side of the base plate, and a reinforcing plate 403 fixedly connected to the base plate and located outside the two side plates. The reinforcing plate 403 is connected to the side plate 402 on its respective side, and the deflection plate 5 is hinged between the two side plates 402 via a hinge shaft. The reinforcing plate 403 connects the base plate 401 and the side plates 402, thereby improving the structural strength of the hinge base 4.
[0028] In this embodiment, the surface of the soil-breaking shovel 11 is spherical, and its outer periphery is serrated. The serrated outer periphery of the soil-breaking shovel 11 can tear the soil, and the torn soil will spread outward along the spherical surface of the soil-breaking shovel 11 to prevent soil accumulation from affecting the operation of the soil-breaking shovel.
[0029] In this embodiment, the deflection plate 5 is also equipped with a hydraulic adjustment mechanism for adjusting the angle of the breaking shovel 11. The hydraulic adjustment mechanism includes an extension plate 12 vertically connected to one side of the deflection plate 5, and a second connecting plate 13 fixedly connected to the upper end of the rotating shaft and facing the extension plate. A second hydraulic cylinder 14 is pivotally connected to the extension plate 12, and the telescopic end of the second hydraulic cylinder 14 is pivotally connected to the second connecting plate 13. When it is necessary to adjust the breaking angle, the second hydraulic cylinder 14 is controlled to work, and the second hydraulic cylinder 14 drives the rotating shaft 8 to rotate at a certain angle, thereby fine-tuning the angle of the breaking shovel 11.
[0030] The working principle of this embodiment is as follows:
[0031] like Figure 3 As shown, the disc plows described in the utility model are installed at both ends of the rotary tiller 20, that is, the first mounting plate 1 and the second mounting plate 2 are both fixed to the ends of the rotary tiller 20. When tilling the land, the motor drives the soil-breaking shovel 11 to rotate, thereby tearing the soil and improving tillage efficiency and quality. The first hydraulic cylinder 3 drives the deflection plate 5 to swing up and down, thereby adjusting the soil-breaking depth of the soil-breaking shovel 11. The second hydraulic cylinder 14 drives the rotating shaft 8 to rotate at a certain angle, thereby adjusting the soil-breaking angle and improving the convenience of soil breaking.
