Description

Technical Field

[0001] This utility model relates to the field of paddy field graders, and in particular to a paddy field grader. Background Technology

[0002] A paddy field grader is an agricultural machine specifically designed for cultivating paddy fields (such as rice paddies). It is primarily used to level the soil in paddy fields, creating a flat and uniform surface for subsequent agricultural activities such as transplanting and sowing. It is typically used in conjunction with tractors and other power machinery, employing specific working devices to scrape, push, and level the paddy field soil, adapting to the muddy and waterlogged environment of paddy fields.

[0003] In existing technologies, the surface of paddy fields is scraped and leveled by working parts such as shovels to eliminate differences in height within the fields, ensuring uniform water depth and avoiding localized water accumulation that is too deep or too shallow. This provides a consistent water environment for the growth of aquatic crops such as rice. However, some land leveling machines cause unevenness and undulating surfaces due to factors such as uneven soil hardness and slight machine tilt, which affects the quality of subsequent irrigation and rice transplanting. Utility Model Content

[0004] The purpose of this invention is to increase the contact area with the ground, disperse the pressure of the equipment on the soil, and reduce the risk of the machine sinking, especially in deep muddy paddy fields. It provides a paddy field grader that solves the problem of excessive cutting of loose areas of the soil surface in subsequent operations, or insufficient treatment of hard areas, resulting in local unevenness.

[0005] This utility model also provides a paddy field leveling machine as described above, including a frame, a pressure rail rotatably connected to the outside of the frame, a depth limiting roller fixedly connected to the outside of the pressure rail, a plurality of leveling shovels fixedly connected inside the depth limiting roller, and a chain fixedly connected to the outside of the frame.

[0006] According to the present invention, a paddy field leveling machine is provided, wherein a flat rail is rotatably connected to the outside of the chain, and a suspension frame is fixedly connected to the outside of the frame.

[0007] According to the present invention, a paddy field leveling machine has a hydraulic oil tank fixedly connected inside the suspension frame, and a solenoid valve group is fixedly connected to the hydraulic oil tank.

[0008] According to the present invention, a paddy field leveling machine has multiple parallel four-bar linkages externally connected to the frame, and a hydraulic cylinder internally connected to each parallel four-bar linkage.

[0009] According to the present invention, a paddy field leveling machine has an oil inlet pipe fixedly connected to the outside of the oil cylinder, and a rotating rod rotatably connected inside the frame.

[0010] According to the present invention, a paddy field leveling machine has multiple stubble rollers fixedly connected inside the rotating rod, and a speed increaser fixedly connected inside the frame.

[0011] According to the present invention, a paddy field leveling machine has a gear pump fixedly connected to the outside of the speed increaser.

[0012] According to the present invention, a paddy field leveling machine has a locking spline sleeve externally fixedly connected to the speed increaser.

[0013] Beneficial effects:

[0014] 1. This technical solution describes a paddy field grader with a pressure rail installed on the outside of the grading blade. Paddy field soil has high moisture content and weak bearing capacity, making it easy for the equipment to sink into the mud during operation due to its own weight or uneven stress. The pressure rail increases the contact area with the ground, dispersing the pressure exerted by the equipment on the soil and reducing the risk of the machine sinking, especially effective in deep muddy paddy fields.

[0015] 2. An external flat rail is installed on the outside of the chain. In paddy fields, where soil moisture content is high and load-bearing capacity is weak, traditional graders are prone to getting their tires or tracks stuck due to the machine's weight, affecting operational efficiency. The flat rail increases the contact area with the ground, disperses the pressure on the equipment, reduces the ground pressure, and decreases the risk of getting stuck. Attached Figure Description

[0025] Specifically, the power is transmitted to the flat rail 12 via the chain 11 for initial leveling, which causes the stubble roller 5 to break up the stubble, the compactor rail 6 to compact the shallow soil, the depth limiting roller 7 to ensure stable working depth, and the leveling shovel 13 to complete fine leveling.

[0026] The chain 11 is externally rotatably connected to the flat rail 12, and the frame 1 is externally fixedly connected to the suspension frame 2.

[0027] The suspension frame 2 is internally fixedly connected to a hydraulic oil tank 3, and the hydraulic oil tank 3 is fixedly connected to a solenoid valve assembly 14.

[0028] Pressurized oil is delivered to the solenoid valve assembly 14 via the oil inlet pipe 10, controlling the extension and retraction of the oil cylinder 9, which in turn drives the parallel four-bar linkage 8 to adjust the height of the working component.

[0029] The frame 1 is externally rotatably connected to multiple parallel four-bar linkages 8, and the parallel four-bar linkages 8 are internally rotatably connected to hydraulic cylinders 9.

The tractor's power drives the gear pump 16 through the speed increaser 15, which draws oil from the hydraulic oil tank 3 and delivers the pressurized oil to the solenoid valve group 14 through the oil connection pipe 10. This controls the extension and retraction of the oil cylinder 9, which in turn drives the parallel four-bar linkage 8 to adjust the height of the working parts. At the same time, the power is transmitted through the chain 11 to the flat rail 12 for initial leveling, which causes the stubble roller 5 to break up the stubble, the compactor rail 6 to compact the shallow soil, the depth limiting roller 7 to ensure stable working depth, and the leveling shovel 13 to complete fine leveling. All rotating parts are fixed by the locking spline sleeve 17, realizing efficient leveling of paddy fields.
