They have strong soil crushing ability, flat ground after plowing, and can also cut up root stubble buried under the surface to provide a good seed bed for later sowing. Traditional rotary tillers are divided into single-axis and double-axis. Compared with single-axis, double-axis rotary tillers can achieve the effect of single-axis operations twice in one operation, significantly improving work efficiency.

[0043] Embodiment 2

[0044] Embodiment 2 is based on the structure of embodiment 1, and the lubrication device 8 is improved. Figure 5 In the figure, the moving direction represents the moving direction of the entire rotary tiller, and the sliding direction represents the sliding direction of the oiling structure 803 inside the input gear 602;

[0045] See also Figure 5According to the movement direction of the entire rotary tiller, it can be known that the rotation direction of the input gear 602, the output gear I604, the transition gear II605, and the output gear II607 is counterclockwise, and the transition gear I603 and the transition gear IV606 are clockwise.

[0046] See also Figure 5 The lubricating device 8 includes an oil filling port 801 and an oil storage structure 802. The oil storage structure 802 and the oil filling port 801 are fixedly installed on the side wall of the gear box housing 601. The lubricating oil is filled into the oil storage structure 802 through the oil filling port 801. An oil coating structure 803 is fixedly installed on the side of the oil storage structure 802 close to the gear. The length of the oil coating structure 803 is greater than or equal to the circumference of the side wall of the input gear 602 between the input gear 602 and the output gear II 607, so that when one end of the oil coating structure 803 is transmitted at the input gear 602, the other end can realize the transmission function with the output gear II 607 ​​after passing through the positions of the transition gear I 603 and the output gear I 604. The oil coating structure 803 is made of rubber. A corner protrusion 804 is provided on 02, and the position of the corner protrusion 804 is between the transition gear I 603 and the transition gear II 605. The shape of the corner protrusion 804 is a right angle. The shape of the corner protrusion 804 is designed so that the contact surface between the transition gear II 605 and the corner protrusion 804 and the right angle side close to the corner protrusion 804 are in a parallel state, so that when the oiling structure 803 slides to the top of the transition gear II 605, the direction of gravity is perpendicular to the contact plane of the transition gear II 605 and the corner protrusion 804, so that the oiling structure 803 can better achieve the lubrication effect. The lubrication device 8 includes an indirect lubrication structure 805, and the indirect lubrication structure 805 is installed between the transition gear I 603 and the gear box housing 601.

[0047] The shape design of the oil storage structure 802 will ensure that the oil-coating structure 803 will only be in transmission contact with the input gear 602, the transition gear II 605, and the output gear II 607. Since among the six gears, only the three counterclockwise gears have the same rotation speed and direction, the transmission force can be maximized through the transmission of these three gears. In addition, the gears with the same rotation speed and direction can effectively prevent the oil-coating structure 803 from bulging due to the speed difference. At the same time, it can also effectively prevent the clockwise gear from contacting the oil-coating structure 803, resulting in pulling between the clockwise size and the counterclockwise size, causing the oil-coating structure 803 to be damaged.

[0048] refer to Figure 6 and Figure 8 The oil storage structure 802 includes an oil storage shell 8021. The oil storage shell 8021 is made of hard material. The oil storage shell 8021 is an open cavity. The two side walls of the cavity of the oil storage shell 8021 are provided with slide grooves. A sliding block 8022 is movably installed in the slide groove. An oil storage capsule 8023 is installed on the sliding block 8022. The oil storage capsule 8023 and the inner cavity of the oil storage shell 8021 form an oil storage cavity 8024. The oil storage cavity 8024 is connected to the oil filling port 801. The oil storage The capsule 8023 is made of elastic rubber material. The oiling structure 803 includes an oiling block 8031. The oiling block 8031 ​​is fixed on the side of the oil storage capsule 8023 away from the oil storage shell 8021. The oil storage capsule 8023 and the oiling block 8031 ​​are integrally formed.

The fixed hard plate 8025 has weak magnetism. 25 is provided with an oil hole 8026, and the oiling block 8031 ​​is provided with an oil storage structure 8032, and the oil storage structure 8032 can penetrate the oiling block 8031, so that the lubricating oil in the oil storage cavity 8024 is stored in the hole cavity of the oil storage structure 8032 through the oil hole 8026. After the oiling block 8031 ​​contacts and squeezes the gear, the lubricating oil will flow out of the hole cavity of the oil storage structure 8032 into the oiling block 8031 ​​to lubricate the gear. A strip-shaped sliding bar 8033 is also installed on the side of the oiling block 8031 ​​close to the gear. The sliding bar 8033 is evenly distributed on the surface of the oil storage structure 802. The oil storage structure 8032 and the sliding bar 8033 are made of rubber material, so that when the input gear 602, the transition gear II 605, and the output gear II 607 ​​rotate, they can partially engage the sliding bar 8033, so that the oiling block 8031 ​​slides along the gear box housing 601.

[0049] The shape of the oil storage structure 8032 is similar to a ball-and-stick model of a crystal. An oil outlet hole is provided on one side of the oiling block 8031 ​​close to the sliding bar 8033. A plurality of spherical holes are provided inside the oiling block 8031. A portion of the spherical holes close to the oil storage cavity 8024 is connected to the oil through hole 8026. The spherical holes close to the sliding bar 8033 are connected to the oil outlet hole. A fine oil passage is provided between the remaining spherical holes in the middle of the oiling block 8031, so that the spherical holes in the middle of the oiling block 8031 ​​are connected to each other. The shape of the oil storage structure 8032 inside the entire oiling block 8031 ​​can be The structure is a combination of multiple diamond ball-and-stick structures. The purpose of this structure is to ensure that the oiling structure 803 and the oil storage bag 8023 can realize the overall transmission. The amount of oil lubricating oil for each gear can be limited by storing oil in the oiling block 8031. Most of the oil will be stored in the spherical hole in the middle of the oiling block 8031. Only when the gravity of the lubricating oil in the oil storage chamber 8024 and the weak magnetic force of the oil hole 8026 are combined, the oiling block 8031 ​​will contact the gear and squeeze the oiling block 8031, so that the lubricating oil in the spherical hole is squeezed out and flows from the oil outlet to the gear, thereby realizing gear lubrication.

[0050] See also Figure 7, a cross-sectional view of the indirect lubrication structure 805 from the BB angle, the indirect lubrication structure 805 comprises an indirect lubrication ring 8051, the inner shape of the indirect lubrication ring 8051 is the same as that of the oil storage structure 8032, a rotating shaft 8052 is movably installed in the middle of the indirect lubrication ring 8051, the rotating shaft 8052 has a weak magnetism, the indirect lubrication ring 8051 can rotate circumferentially along the central axis of the rotating shaft 8052 of the lubrication structure, and a moving block 8053 is fixedly installed at the bottom of the rotating shaft 8052 of the lubrication structure, and the moving block 8053 is fixedly installed at the bottom of the rotating shaft 8052 of the lubrication structure. The outer sleeve of the movable block 8053 is provided with an indirect lubrication structure limit frame 8054, which is fixedly connected to the gear box housing 601, and the inner portion of the limit frame 8054 is provided with a slide groove for the sliding of the movable block 8053, and the sliding direction of the movable block 8053 is parallel to the transverse meridian of the transition gear I 603. When the oiling structure 803 slides along the inner wall of the gear box housing 601, if it slides to the position of the indirect lubrication structure 805, the rotating shaft 8052 has weak magnetism, and the fixed The fixed hard plate 8025 also has weak magnetism, and the magnetic force between the magnetic strips is greater than the magnetic force between the magnetic strips and the stainless steel gear. At this time, the indirect lubrication structure 805 will be driven to move towards the oiling structure 803, so that the indirect lubrication ring 8051 and the oiling block 8031 ​​are subjected to extrusion pressure, and the lubricating oil on the oiling block 8031 ​​is squeezed into the crystal ball-and-stick structure of the indirect lubrication ring 8051, so that the lubricating oil is stored in the indirect lubrication ring 8051. When the entire oiling structure 803 slides to leave the area where the indirect lubrication structure 805 is located, the suction force between the magnetic strips disappears, and only the suction force between the lubrication structure shaft 8052 and the gear makes the lubrication structure shaft 8052 contact with the gear of the transition gear Ⅰ603, and the lubricating oil is squeezed onto the transition gear Ⅰ603 to achieve a lubrication effect. In this way, when the oiling structure 803 passes through the transition gear Ⅰ603, the transition gear Ⅰ603 can be lubricated without affecting the normal sliding of the oiling structure 803.

[0051] In summary, the entire workflow is as follows:

[0052] Lubricating oil is injected into the oil storage chamber 8024 from the oil filling port 801. When the input gear 602 rotates, the oil block 8031 ​​passes through the indirect lubrication structure 805, the transition gear I 603, the output gear I 604, and finally transmits to the output gear II 607. During the sliding process of the entire oiling structure 803, it only contacts with the input gear 602, the output gear II 607, and the transition gear II 605. Through the gravity of the lubricating oil in the oil storage chamber 8024 and the weak magnetism of the fixed hard plate 8025, the oil block 8031 ​​rotates counterclockwise. The gears are in contact with each other, and the lubricating oil stored in the oil storage structure 8032 is squeezed into the gears by squeezing. Since the transmission of the output gear Ⅰ604 has no gear in direct contact with it, in order to speed up the lubrication speed, an indirect lubrication structure 805 is set on the side of the transition gear Ⅰ603, and the indirect lubrication ring 8051 and the oiling block 8031 ​​are both provided with an oil storage structure 8032. At this time, under the weak magnetic effect of the lubricating structure shaft 8052 and the fixed hard plate 8025, the lubricating oil will be squeezed and transferred, so that the lubricating structure shaft 8052 can be indirectly The transition gear I603 is then lubricated. At this time, the transition gear I603 transfers the lubricating oil to the output gear I604 during the rotation process, and indirectly lubricates the output gear I604. The transition gear IV606 can be directly lubricated because the output gears II607 and the transition gear II605 on both sides can achieve direct lubrication, and the lubricating oil transfer speed is fast. Part of the lubricating oil can be transferred to the transition gear IV606, thereby achieving the lubrication effect of the transition gear IV606. In this process, due to the rotation of the gear, under the action of centrifugal force, the excess lubricating oil will be thrown onto the oil storage structure 802 and the oiling structure 803. Part of the lubricating oil will be absorbed by the oil storage structure 8032, reducing the problem of over-lubrication of a single gear, and the other part will flow to the bottom of the oil storage structure 802. The lubricating oil at the bottom will flow to the space above the input gear 602 as the oil storage structure 802 rotates, and then under the action of gravity, the gear is replenished with lubrication to improve the lubrication effect until the lubricating oil in the entire oil storage cavity 8024 is used up. This lubrication is completed and lubrication is performed again after the next lubrication cycle.
