Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, in particular to a hydraulic lifting farmland management machine. Background Art

[0002] The farmland management machine is powered by a small diesel engine or gasoline engine, and has the characteristics of light weight, small size, simple structure, etc. The farmland management machine is widely used in dry land, paddy fields, orchards, etc. in plains, mountains, and hills. By connecting with different operating devices (including furrow openers, ridgers, rotary tillage cutters, etc.), it can realize different operations such as furrowing, backfilling, ridging, and rotary tillage, and has a wide range of applications. At the same time, the farmland management machine can be freely used in the field, which is convenient for users to use and store, and is flexible to operate, eliminating the trouble that large agricultural machinery cannot enter mountain fields. It is an agricultural machinery designed for small farmland farming.

[0003] In order to adapt to working devices with different structures and different working depth requirements, it is necessary to be able to adjust the working depth of different working devices. When adjusting the depth of traditional farm management machines, a depth adjustment rod is installed on the farm management machine, and then before the operation is carried out, the depth of the working device entering the ground is manually adjusted through the depth adjustment rod before the operation is carried out.

[0004] For example, the utility model patent with the authorization announcement number CN209949817U discloses a depth adjustment rod for a farmland management machine, which is installed at the rear of the machine body. By setting the rod body and the positioning pin to cooperate, the depth rod is inserted into the soil to adjust the tillage depth. However, this traditional method of adjusting the depth of penetration has the following disadvantages:

[0005] 1. The operating depth must be determined before the operation is carried out, and it cannot be adjusted in time according to the actual ground conditions, and the adaptability is poor; when the depth needs to be changed, the operation must be stopped before it can be carried out, which is time-consuming and reduces work efficiency;

[0006] 2. It is necessary to manually change the different insertion positions of the positioning pin to change the depth of the depth rod inserted into the soil, which is cumbersome to operate; when adjusting the position of the positioning pin, it is necessary to lift one end of the farm management machine to adjust it, which is labor-intensive.

[0045] In the present utility model, the power device 5 provides power for the farmland management machine. Preferably, the power device 5 adopts a gasoline engine or a diesel engine. The power output shaft of the power device 5 is directly connected to the power input end of the gearbox 2. The power device 5 is fixedly connected to the outer shell of the gearbox 2. When the gearbox 2 rotates around the travel output shaft, the power device 5 is driven to rotate around the travel output shaft. The power output of the power device 5 is transmitted through the gearbox 2 and output through the travel output shaft 21, the hydraulic output shaft 22 and the operation output shaft 23 respectively, providing power for walking, hydraulic lifting and operation. The operation output shaft 23 is used to connect with the operation device 9. The operation device 9 includes but is not limited to a furrow opener, a ridger, a rotary tillage cutter, etc., to achieve different operations such as furrowing, backfilling, ridging, and rotary tillage.

[0046] Among them, the travel output shaft 21, the hydraulic output shaft 22 and the working output shaft 23 are all arranged horizontally.

[0047] In order to facilitate the hinge connection between the piston rod 42 and the gearbox 2, a connecting seat 24 is installed on the gearbox 2, and the piston rod 42 is hinged to the connecting seat 24, and the connecting seat 24 is located between the travel output shaft 21 and the working output shaft 23.

[0052] The farmland management machine of the present application can adjust the working depth of the working device 9 before the operation, and can also adjust the working depth of the working device 9 at any time during the operation based on the actual ground conditions, and the adjustment method is the same. When adjusting, the piston rod 42 is controlled to extend or retract through the diverter valve 8 to change the overall length of the lifting cylinder 4. By controlling the piston rod 42 to extend, the length of the lifting cylinder 4 is lengthened, and the piston rod 42 and the gearbox 2 are hinged between the travel output shaft 21 and the work output shaft 23. The lifting cylinder 4 pushes the gearbox 2 to rotate around the axis of the travel output shaft 21. Specifically, the work output shaft 23 moves toward the direction close to the ground, lowering the height of the working device 9 installed on the work output shaft 23, thereby changing its working depth and making it deeper; or, the piston rod 42 is controlled to retract, so that the length of the lifting cylinder 4 becomes shorter, the work output shaft 23 moves away from the ground, and the height of the working device 9 installed on the work output shaft 23 is raised, thereby changing its working depth and making it shallower. During this adjustment process, there is no need to stop the operation, which improves the adjustment efficiency. Moreover, there is no need for manual adjustment, and it can be achieved by lifting the oil cylinder, which is simple to operate and reduces labor intensity.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
