[0024] As attached Figure 1 To be continued Figure 5 As shown:

[0025] This utility model provides an orchard grass-pressing device with terrain-adaptive function, including an outer mounting base 1. The bottom of the outer mounting base 1 has a trapezoidal structure with a higher front and lower rear. Two sets of support wheels 101 are rotatably arranged on the lower rear sides of the outer mounting base 1. Pressure roller connecting rods 102 are hinged to the lower front sides of both sides of the outer mounting base 1. A front pressure roller 103 is rotatably arranged in the middle of the front end of the two sets of pressure roller connecting rods 102. Control connecting rods 104 are hinged to the outside of the pressure roller connecting rods 102. A transmission frame 105 is rotatably arranged in the middle of the top of the control connecting rod 104. The transmission frame 105 slides vertically on the front side of the outer mounting base 1. A front hydraulic cylinder 106 is fixedly arranged on the upper front side of the outer mounting base 1. The telescopic end of 06 is fixedly installed above the transmission frame 105; a hydraulic oil tank 2 is fixedly installed on the top front side of the assembly outer seat 1, and an adjustment hole is provided above the hydraulic oil tank 2 as needed to ensure the pressure inside the hydraulic oil tank 2; a control compartment 3 is fixedly installed on the top rear side of the assembly outer seat 1, and a processor and an electronic level are installed inside the control compartment 3; a connecting pipe frame 4 is fixedly installed in the upper middle part of the interior of the assembly outer seat 1, and two sets of rear hydraulic cylinders 5 are fixedly installed at the bottom of the connecting pipe frame 4; a rear grass pressing frame 6 for secondary grass pressing is vertically slidable on the interior rear side of the assembly outer seat 1, and two sets of connecting seats 601 are fixedly installed on the top of the rear grass pressing frame 6, and the top of the connecting seat 601 is fixedly connected to the telescopic end of the rear hydraulic cylinder 5.

[0026] The front oil pump 201 is fixedly connected to the front side of the hydraulic oil tank 2, and the front oil pump 201 is connected to the front hydraulic cylinder 106 by a pipeline; the rear oil pump 202 is fixedly installed on the rear side of the hydraulic oil tank 2, and the rear oil pump 202 is connected to the two sets of rear hydraulic cylinders 5 by a pipeline passing through the connecting pipe frame 4.

[0027] The main body of the rear hay pressing frame 6 is a square frame structure. Two sets of guide rods 602 are fixedly installed on the inner walls of both sides of the rear hay pressing frame 6. Five sets of staggered saw slots 603 are opened at the bottom of the rear hay pressing frame 6.

[0028] The rear grass pressing frame 6 is equipped with a cutter 7. Two sets of slides 701 are fixed on both sides of the cutter 7. The slides 701 slide outside the guide rod 602. A spring is sleeved on the lower part of the guide rod 602.

[0029] The cutter 7 has five sets of linkage shafts 702 rotatably mounted inside, and the five sets of linkage shafts 702 are connected by synchronous belts. A drive motor 703 is fixedly mounted on the top of the cutter 7, and the drive motor 703 is connected to the linkage shaft 702 in the middle by bevel gear transmission. Five sets of circular saw frames 704 are fixedly mounted on the lower front and rear sides of the cutter 7. A circular saw 705 is rotatably mounted below each of the circular saw frames 704 and the circular saw 705. Each circular saw 705 is connected to a set of linkage shafts 702 by synchronous belt transmission. The circular saw 705 can pass through the saw through slot 603.

[0030] Two sets of secondary hydraulic cylinders 8 are fixedly installed inside the upper part of the rear grass pressing frame 6. The telescopic end of the secondary hydraulic cylinder 8 is fixedly connected to the top of the cutter 7. The top of the secondary hydraulic cylinder 8 passes through the rear grass pressing frame 6 and is connected to a solenoid valve 9. The other end of the solenoid valve 9 is connected to the outside of the connecting seat 601. When the solenoid valve 9 is opened, the rear hydraulic cylinder 5 is connected to the secondary hydraulic cylinder 8.

[0031] like Figure 1-5 As shown, the outer mounting base 1 is moved to the orchard by manual pushing to press the grass;

[0032] The front pressure roller 103 directly compresses the turf by its own weight; the level in the control chamber 3 automatically detects the orchard terrain. When it encounters a raised mound, the processor controls the front oil pump 201 to input hydraulic oil into the front hydraulic cylinder 106 after the front pressure roller 103 crosses the mound, pushing the control linkage 104 and the front pressure roller 103 downward to align the rear turf pressing frame 6 with the slope of the mound; conversely, the front pressure roller 103 is raised, and the rear turf pressing frame 6 is tilted in the opposite direction to press the turf on the other side of the mound.

[0033] The rear oil pump 202 inputs hydraulic oil into the rear hydraulic cylinder 5, which pushes the rear grass pressing frame 6 downward to contact the ground, completing the secondary grass pressing; when the rear oil pump 202 works in the reverse direction, the rear grass pressing frame 6 is retracted, and multiple grass pressing is achieved by repeatedly raising and lowering the rear grass pressing frame 6. Example 2

[0034] Based on Embodiment 1, a traveling machine can be installed behind the outer mounting base 1 for driving. The outer mounting base 1 and the traveling machine are hinged to maintain the adjustable angle of the outer mounting base 1. Example 3

[0035] Based on Example 1, if weeds need to be cut, open the solenoid valve 9, and the hydraulic oil will fill the rear hydraulic cylinder 5 and continue to flow into the secondary hydraulic cylinder 8. The secondary hydraulic cylinder 8 will extend and drive the cutter 7 to move down.

[0036] Start the drive motor 703 to drive the linkage shaft 702 to rotate, and each set of linkage shafts 702, together with the conveyor belt, drives the circular saw 705 to rotate.

[0037] The circular saw 705 descends and passes through the saw groove 603 to cut and flatten the grass, achieving the effect of weeding.

[0038] When the cutter 7 is raised, the spring outside the guide rod 602 plays a role in ensuring that the secondary hydraulic cylinder 8 retracts first, and then the rear hydraulic cylinder 5 retracts, thus achieving two-stage sequential control.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In this utility model, when in use, the outer mounting base 1 is moved to the orchard for grass pressing by manual pushing or a traveling machine pushing.

[0041] The front pressure roller 103 can directly compress the turf by its own weight; the level in the control chamber 3 can automatically detect the terrain of the orchard. When it encounters a raised mound, the processor controls the front pressure roller 103 to cross the mound, and the front oil pump 201 inputs hydraulic oil into the front hydraulic cylinder 106 to push the control linkage 104 and the front pressure roller 103 downward, so that the rear turf pressing frame 6 is aligned with the slope of the mound; conversely, the front pressure roller 103 is raised to tilt the rear turf pressing frame 6 in the opposite direction, so that the turf can be pressed on the other side of the mound.

[0042] The rear oil pump 202 inputs hydraulic oil into the rear hydraulic cylinder 5, which pushes the rear hay press 6 downward to make it contact the ground for secondary hay pressing. The rear oil pump 202 can work in reverse to retract the rear hay press 6. The rear hay press 6 can be raised and lowered repeatedly to perform multiple hay pressing operations.

[0043] Above this, the grass can be cut. Open the solenoid valve 9 to fill the rear hydraulic cylinder 5 with hydraulic oil and then continue to flow into the secondary hydraulic cylinder 8. The secondary hydraulic cylinder 8 extends and moves the cutter 7 downward. Start the drive motor 703 to drive the linkage shaft 702 to rotate. Each linkage shaft 702, together with the conveyor belt, drives the cutting circular saw 705 to rotate, providing the cutting function. After the cutting circular saw 705 passes through the saw groove 603, it cuts the flattened grass, which can achieve the weeding effect.

[0044] When the cutter 7 is raised, the spring outside the guide rod 602 provides force to ensure that the secondary hydraulic cylinder 8 retracts first, and then the rear hydraulic cylinder 5 retracts, thus achieving two-stage sequential control.
