DETAILED DESCRIPTION

[0049] The utility model is in brief described below in combination with the drawings.

[0050] As Figures 1 to 5 The utility model discloses a high -efficient energy -conserving ploughing machine, including frame 1, walking wheel 2, walking driver 3, front driver 4, front plough knife 5, rotary telescopic drive part 6, rear plough knife 7 and rear driver 8,

[0051] Walking wheel 2 rotation setting is in frame 1.

[0052] Walking driver 3 is fixed in frame 1 and is used to drive walking wheel 2 rotation.

[0053] Front driver 4 is fixed in frame 1 and is used to drive front plough knife 5 rotation.

[0054] Rotary telescopic drive part 6 sets up in frame 1 and is used to drive rear plough knife 7 lift and telescopic.

[0055] Rear driver 8 is fixed in rotary telescopic drive part 6 and is used to drive rear plough knife 7 rotation.

[0056] Through the cooperation of the front plow 5 and the rear plow 7, a wider plowing area can be covered, and the plowing efficiency is improved.

[0057] The design of the rotating telescopic driving member 6 allows the rear plow 7 to be raised and lowered in the vertical direction and to be telescoped in the horizontal direction, so that the plowing machine can plow flexibly to adapt to different terrains and plowing depths.

[0058] On the other hand, in terrains with slopes such as mountains and hills, traditional plowing machines often have difficulty climbing slopes due to insufficient driving force, which not only limits the plowing range but also increases the risk of mechanical failure and operation. The rotating telescopic driving member 6 designed in this application can effectively control the contact between the rear plow 7 and the ground, thereby enhancing the driving force of the plowing machine and improving its performance in complex terrains, especially when climbing slopes.

[0059] All key components are fixed or arranged on the frame 1, making the overall structure compact and facilitating operation and maintenance.

[0060] The walking driver 3, the front driver 4, and the rear driver 8 are responsible for walking, rotating the front plow 5, and rotating the rear plow 7, respectively, with clear power distribution, improving work efficiency and machine stability.

[0061] When working, the plowing machine uses the walking driver 3 to drive the walking wheel 2 to rotate, realizing the movement of the machine; the front driver 4 drives the front plow 5 to rotate for preliminary plowing; the rotating telescopic driving member 6 adjusts the position and angle of the rear plow 7 according to plowing requirements; and the rear driver 8 drives the rear plow 7 to rotate, completing further plowing work.

[0062] As shown in Figure 4 the rotating telescopic driving member 6 of the present embodiment includes a lifting mechanism, a telescopic mechanism, and a mounting mechanism. The lifting mechanism is fixed to the frame 1 at one end and is used to drive the telescopic mechanism to lift and lower, and the telescopic mechanism is used to drive the mounting mechanism to telescope.

[0063] The rotating telescopic driving member 6 combines lifting and telescoping functions, meeting the needs of different application scenarios and improving the flexibility and applicability of the equipment.

[0064] The lifting mechanism can stably drive the telescopic mechanism to lift and lower, and the telescopic mechanism can accurately drive the mounting mechanism to telescope, ensuring the efficiency and stability of the driving process.

[0065] The lifting mechanism and the telescopic mechanism can be linear motors, electric cylinders, air cylinders, oil cylinders, gas-liquid booster cylinders, pulling arm telescopic modules, forklift mast type telescopic modules, scissor type telescopic arm modules, and rack or screw telescopic modules, so as to realize the lifting of the telescopic mechanism driven by the lifting mechanism and the telescoping of the mounting mechanism driven by the telescopic mechanism.

[0066] As shown in Figure 4 The lifting mechanism of the embodiment includes a first actuator 61, a first transmission member 62, and a first transmission device 63.

[0067] The telescopic mechanism includes a second actuator 64.

[0068] The mounting mechanism includes a mounting frame 65.

[0069] The first actuator 61 is fixed to the rack 1, and the first transmission member 62 is rotationally arranged on the rack 1. The first actuator 61 drives the first transmission member 62 to rotate through the first transmission device 63, so that the rotating telescopic driving member 6 realizes lifting.

[0070] The second actuator 64 is connected between the first transmission device 63 and the mounting frame 65 and is used to drive the mounting frame 65 to telescope, so that the rotating telescopic driving member 6 realizes telescoping.

[0071] Through the cooperation of the first actuator 61, the first transmission device 63, and the first transmission member 62, the rotating telescopic driving member 6 can be flexibly lifted, so that the rear plow 7 is more closely contacted with the ground, thereby enhancing the driving force of the plowing machine, and especially in complex terrain and climbing, showing higher adaptability and stability.

[0072] The introduction of the second actuator 64 enables the mounting frame 65 and the rear plow 7 to realize telescoping in the horizontal direction, adjusts the plowing range according to the plowing demand, improves the plowing efficiency, and reduces unnecessary energy consumption.

[0073] By precisely controlling the actions of the first actuator 61 and the second actuator 64, the position and angle of the rear plow 7 can be precisely adjusted, meeting the demand of different terrains and plowing depths, and improving the precision and quality of plowing.

[0074] The first actuator 61 (such as a motor, a hydraulic cylinder, or a hydraulic motor) serves as a power source, and transmits power to the first transmission member 62 (such as a rotating shaft or a screw) through the first transmission device 63 (such as a gear box, a speed reducer, or a chain transmission device), so that the first transmission member 62 rotates, and the rotating telescopic driving member 6 realizes lifting. In the embodiment, the first actuator 61 is a motor, the first transmission device 63 is a gear box, and the first transmission member 62 is a rotating shaft.

[0075] Meanwhile, the second actuator 64 (such as a linear motor, an electric cylinder, a pneumatic cylinder, an oil cylinder, a gas-liquid booster cylinder, a pull arm lifting and retracting module, a forklift gantry lifting and retracting module, a scissor arm module, and a rack or screw lifting and retracting module) is connected between the first transmission 63 and the mounting frame 65, and drives the mounting frame 65 to realize horizontal extension and retraction through the extension and retraction action of the second actuator 64. This design enables the rotary extension and retraction drive 6 to flexibly adjust the position and angle of the rear tiller 7 in the vertical and horizontal directions according to the tillage requirements, thereby improving the adaptability and tillage efficiency of the land tiller. In the embodiment, the second actuator 64 is taken as an example of an electric cylinder. In actual use, the number of second actuators 64 can be one, two or more, which is set according to the requirements.

[0076] As shown in Figure 4 , the rear drive 8 of the embodiment includes a third actuator 81, a second transmission 82, and a second transmission 83.

[0077] The third actuator 81 is fixed to the mounting frame 65.

[0078] The third actuator 81 drives the second transmission 83 to rotate through the second transmission 82.

[0079] The second transmission 83 is in transmission connection with the rear tiller 7.

[0080] The rear drive 8 is directly connected with the mounting frame 65 through the compact design of the third actuator 81, the second transmission 82 and the second transmission 83, which improves the integration and space utilization of the whole system, and makes the land tiller structure more compact, facilitating operation and transportation.

[0081] The third actuator 81 as a power source efficiently transmits power to the second transmission 83 through the second transmission 82, and then drives the rear tiller 7 to till. This design ensures the efficiency and stability of power transmission, and through precise control of the output of the third actuator 81, the movement speed and position of the rear tiller 7 can be precisely controlled to meet different tillage requirements. It can also be adjusted according to different tillage conditions and soil hardness, and by changing the output power and speed of the third actuator 81, the adaptability and flexibility of the land tiller are enhanced.

[0082] The third actuator 81 is usually powered by an electric motor or a hydraulic motor to generate rotary motion. Then, the rotary motion is transmitted to the second transmission 83 through the second transmission member 82 (such as a gear shaft or a chain sprocket). Finally, the second transmission 83 drives the rotation of the rear tiller 7 through a transmission connection (such as gear meshing, chain connection, or connecting rod, etc.) to achieve the tillage function. In this embodiment, the third actuator 81 is an electric motor, the second transmission member 82 is a gear shaft, the second transmission 83 is a chain sprocket transmission assembly, and the second transmission 83 drives the rear tiller 7 through a connecting rod.

[0083] In another embodiment, the second transmission 83 can be a speed reducer or a speed increaser for adjusting the speed and torque of the rotary motion to meet the driving requirements of the rear tiller 7.

[0084] As shown in Figure 4 The mounting bracket 65 of this embodiment includes a connecting portion 651 and an extension portion 652.

[0085] The connecting portion 651 is connected to the third actuator 81, and the extension portion 652 is connected to the end of the connecting portion 651 away from the third actuator 81, realizing the connection of the third actuator 81, the connecting portion 651, and the extension portion 652.

[0086] The connecting portion 651 is provided with a first mounting cavity 653 for accommodating the second transmission member 82, and the first mounting cavity 653 provides convenience for the installation of the second transmission member 82.

[0087] The inside of the extension portion 652 is provided with a second mounting cavity 654, and the second transmission 83 is arranged in the second mounting cavity 654. The second mounting cavity 654 provides convenience for the installation of the second transmission 83.

[0088] As shown in Figure 5 The rear tiller 7 of this embodiment includes at least two end plates 71, a plurality of long harrow blades 72, and a plurality of short harrow blades 73.

[0089] The end plate 71 is provided with a plurality of mounting grooves in the radial direction;

[0090] The plurality of long harrow blades 72 are respectively fixed to the corresponding mounting grooves of the at least two end plates 71;

[0091] The plurality of short harrow blades 73 are respectively fixed to the plurality of long harrow blades 72.

[0092] The rear tiller 7 realizes multi-level cutting and crushing of the soil by combining the long harrow blades 72 and the short harrow blades 73. The long blades are mainly used for preliminary cutting and turning over the soil, while the short blades further refine the soil particles, enhancing the tillage effect and making the soil more loose, which is beneficial to the growth of crops.

[0093] A plurality of mounting grooves are arranged radially on the end plate 71 of the rear tillage knife 7, which can flexibly adjust the number and position of the long rake blades 72 and the short rake blades 73. This design enables the rear tillage knife to adapt to different soil textures and tillage depths.

[0094] As shown in Figure 3 , the front tillage knife 5 of the embodiment includes a front main shaft 51 and a plurality of front blades 52 arranged on the front main shaft 51.

[0095] The front blades 52 are arranged radially along the front main shaft 51.

[0096] The front blade 52 includes a mounting portion 521 and a bent portion 522, which are integrally formed. The front blade 52 is connected to the front main shaft 51 through the mounting portion 521.

[0097] Since the mounting portion 521 and the bent portion 522 are integrally formed, this design not only enhances the overall strength of the blade, but also reduces the risk of blade breakage or deformation caused by long-term use or impurities in the soil.

[0098] The front tillage knife 5 can cover a wider tillage area at one time by arranging a plurality of front blades 52 on the front main shaft 51, and these blades are arranged radially along the front main shaft, which significantly improves the tillage efficiency.

[0099] The design of the front blade 52 combines the mounting portion 521 and the bent portion 522. The presence of the bent portion 522 enables the blade to cut into the soil better during tillage, especially when encountering relatively hard soil layers. The bent portion 522 can provide additional cutting force to enhance the cutting effect of the soil.

[0100] As shown in Figure 2 and Figure 3 , the front driver 4 of the embodiment includes a transmission 41 and a walking transmission 42. The transmission 41 is fixed to the frame 1 and is in transmission connection with the front driver 4. The walking transmission 42 is in transmission connection with the transmission 41 and drives the front main shaft 51 to rotate.

[0101] The front driver 4 can realize precise control of the rotation speed of the front main shaft 51 through the combination of the transmission 41 and the walking transmission 42. This control capability enables the front tillage knife 5 to be flexibly adjusted according to factors such as soil texture, tillage depth, and crop type, thereby improving the flexibility and adaptability of tillage.

[0102] The walking transmission 42 is a walking transmission box, such as a 186 micro tiller walking box assembly.

[0103] As shown in Figure 2 and Figure 3As shown, the front drive 4 of the present embodiment is also provided with a generator 43 and a battery. The front drive 4 drives the generator 43 to generate electricity, and the electricity of the generator 43 is stored in the battery (not shown).

[0104] The battery is electrically connected to the electrical equipment of the land tiller.

[0105] The front drive 4 drives the generator 43 to generate electricity, realizing self-sufficiency of energy. This design enables the land tiller to generate electricity by itself during the tillage process, reducing the dependence on external power supply and improving the autonomy and flexibility of the equipment.

[0106] The front drive 4 is a motor, and in other embodiments, the front drive 4 and the generator 43 are integrated to form a hybrid engine. The hybrid engine combines the functions of a traditional engine and a generator, and can flexibly adjust the power output according to the tillage requirements and working conditions. When high power output is required, the engine can run at full capacity; when the power requirement is low, the generator can assist in providing electricity, or further improve energy utilization efficiency through the recovery of braking energy, etc.

[0107] The battery, as an electrical energy storage device, can provide stable power supply when the generator 43 cannot generate electricity or the power demand suddenly increases. This design enhances the reliability and stability of the equipment in complex environments, ensuring the normal operation of the functions of the land tiller. The use of hybrid power driving mode reduces the use cost of the land tiller.

[0108] In another embodiment, the land tiller is controlled by a remote system to work, realizing unmanned intelligent operation of the land tiller.

[0109] As Figure 2 As shown, the frame 1 of the present embodiment is provided with a fixing seat 11, and the walking drive 3 is fixed to the fixing seat 11 and in transmission connection with the walking wheel 2. The walking drive 3 is an electric motor, a reduction motor or a hydraulic motor. In the present embodiment, the walking drive 3 is an electric motor.

[0110] The walking wheel 2 includes a wheel body 21 and a harrow tooth 22 arranged on the wheel body 21. The wheel body 21 and the harrow tooth 22 can be metal, non-metal or a combination thereof. The metal material is, for example, iron wheel, steel wheel or aluminum alloy wheel, so that the wheel body 21 and the harrow tooth 22 have high strength and wear resistance. The non-metal material is, for example, rubber wheel, polyurethane wheel or nylon wheel, so that the wheel body 21 and the harrow tooth 22 have certain elasticity and wear resistance. The combination of metal and non-metal materials makes the wheel body 21 and the harrow tooth 22 have high strength, certain elasticity and wear resistance.

[0111] The fixed seat 11 arranged on the frame 1 provides stable support for the walking driver 3, ensuring the stability of the walking wheel 2 during the plowing process. This design helps to reduce the bumping and vibration of the equipment on uneven ground, improves the reliability and durability of the equipment.

[0112] The rolling harrow teeth 22 arranged on the walking wheel 2 can reduce the occurrence of slipping of the walking wheel 2 through the rolling harrow teeth 22. On the other hand, it can also loosen and crush the soil to a certain extent during walking, thereby improving the plowing efficiency. This design enables the land tiller to complete part of the plowing task when moving.

[0113] In other embodiments, the walking wheel 2 can also be a track walking module, and the driving of the track walking module by the walking driver 3 can also realize the walking of the land tiller.

[0114] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
