Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a lifting operation device for agricultural machinery. Background Art

[0002] As an essential mechanical equipment in modern agricultural production, during the process of crop planting, agricultural machinery increasingly replaces manual labor to complete various operations.

[0003] When agricultural machinery performs various operations such as rotary tillage, ditching, and soil ridging, due to the different levels of land leveling and actual soil conditions in different working environments, it is often necessary to adjust the penetration depth of the operation device to ensure the operation effect.

[0004] The operation devices of existing agricultural machinery are often directly connected to the frame of the agricultural machinery. When adjusting the height of the operation device, manual adjustment is required, which is time-consuming and laborious. In addition, due to the working requirements of the operation device, the operation device is often low in height and long in length. When the agricultural machinery needs to be transferred between different working sites, the passing performance of the agricultural machinery is poor, which is likely to cause damage to the operation device by dragging on the ground, making it inconvenient to move. At the same time, due to the low height, the maintenance of the operation device of the agricultural machinery is particularly difficult.

[0005] Therefore, how to enable the penetration depth of the operation device of agricultural machinery to be flexibly adjusted according to the level of land leveling and actual soil conditions, and make the agricultural machinery easy to move, maintain, and repair has become an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0006] The utility model aims at the deficiencies of the prior art and provides a lifting operation device for agricultural machinery with flexible adjustment and convenient movement.

[0007] The utility model is realized through the following technical solutions. A lifting operation device for agricultural machinery is provided, which includes a frame and a transmission device, and further includes a lifting mechanism, a working mechanism, and a transmission mechanism. The lifting mechanism is connected to the frame, the working mechanism and the transmission mechanism are respectively connected to the lifting mechanism, and the working mechanism is in transmission connection with the transmission device of the agricultural machinery through the transmission mechanism.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: through the lifting mechanism, the working mechanism can realize the vertical lifting function, so that the height of the working mechanism can be adjusted according to the level of land leveling and actual soil conditions in different working environments, and then the penetration depth of the working mechanism can be adjusted, thereby improving the operation effect of the working mechanism. By raising the working mechanism through the lifting mechanism, the passing performance of the agricultural machinery can be improved, which is convenient for the agricultural machinery to be transferred between different working sites, and also provides great convenience for the operator to maintain the working mechanism.

[0009] Preferably, the lifting mechanism includes a third mounting member and a first lifting member. The third mounting member is connected to the frame through a first mounting member. The third mounting member is connected to the first lifting member through a first telescopic device. The working device is connected to the first lifting member.

Rollers are rotatably connected to both the left and right sides of the first lifting member. The rollers are in rolling connection with the first guiding groove and the second guiding groove.

[0011] The beneficial effect of adopting the above preferred technical solution is that: through the rollers rotatably connected to both sides of the third mounting member, the first guiding groove, and the second guiding groove, when the first telescopic device drives the first lifting member to lift or lower, it can prevent the first lifting member from twisting, tilting, etc. due to external forces, maintain the stability of the first lifting member, and further avoid damage to the moving parts in the first telescopic device.

[0013] The beneficial effect of adopting the above preferred technical solution is that: through the second telescopic member, the first working member can achieve the function of rotating up and down. Thus, the first working member can not only move up and down but also rotate up and down, enabling the working mechanism to more flexibly adjust the penetration depth and penetration angle, improving the working effect of the working mechanism. At the same time, it can also avoid unnecessary friction and collision between the first working member and sundries such as the ground or stones in the soil while ensuring the penetration depth of the working mechanism, prevent sundries on the ground from entering the moving parts of the working mechanism and causing damage to the working mechanism, and extend the service life of the working mechanism.

[0014] Preferably, at least one working mechanism is provided on the lifting mechanism. The transmission mechanism includes a first rotating shaft. The working mechanism includes a first working member and a second working member. The first rotating shaft is rotatably connected to the first working member.

The second rotating shaft is connected with a second transmission wheel. The first transmission wheel is in transmission connection with the second transmission wheel through a first transmission member.

[0015] The beneficial effects of adopting the above preferred technical solutions are as follows: The first rotating shaft can provide power for one or more working devices simultaneously. When multiple working devices are provided on the lifting mechanism, the synchronism of the multiple working devices during operation can be improved, ensuring the consistency of the operation effect within the operation area.

[0016] Preferably, the first working component is of a hollow structure, and the first transmission wheel, the second transmission wheel, and the first transmission component are all located in the internal cavity of the first working component.

[0017] The beneficial effects of adopting the above preferred technical solutions are as follows: Since the first transmission wheel, the second transmission wheel, and the first transmission component are all located in the internal cavity of the first working component, the housing of the first working component can provide protection for the first transmission wheel, the second transmission wheel, and the first transmission component, preventing damage to the first transmission wheel, the second transmission wheel, and the first transmission component caused by entanglement and collision with sundries during the operation of the working mechanism, which affects the normal operation of the working mechanism.

The ninth mounting component is rotatably connected with an eighth belt pulley. The output shaft of the transmission device is connected with a ninth belt pulley. The second transmission component annularly surrounds the third belt pulley, the eighth belt pulley, and the ninth belt pulley.

[0019] The beneficial effects of adopting the above preferred technical solutions are as follows: Through the first elastic component and the eighth belt pulley, when the lifting mechanism moves up and down, the second transmission component can be tensioned, preventing the second transmission component from falling off when the lifting mechanism moves up and down.
