DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] A paddy field leveling machine with a grass pressing function comprises a vehicle body, one end of which is connected to a lifting and adjusting mechanism 1, the end of which is connected to a main leveling mechanism 2, a first earth-breaking plate 222 is distributed on the bottom surface of the main leveling mechanism 2, a second hydraulic rod 3 is installed on the top of the main leveling mechanism 2, both ends of the main leveling mechanism 2 are slidably connected to auxiliary leveling mechanisms 4, the output end of the second hydraulic rod 3 is rotatably connected to the outer end of the auxiliary leveling mechanism 4, the outer end of the auxiliary leveling mechanism 4 is hinged with an anti-collision plate 7, and an auxiliary earth-breaking mechanism 5 is installed on the upper surface of each of the auxiliary leveling mechanisms 4; the second hydraulic rod 3 is used to drive the auxiliary leveling mechanism 4 to slide and the anti-collision plate 7 to rotate; the actions of the anti-collision plate 7 and the auxiliary earth-breaking mechanism 5 are all completed in association with the actions of the auxiliary leveling mechanism 4;

[0030] The secondary leveling mechanism and the anti-collision plate can be pushed out and retracted by the second hydraulic rod, thereby lengthening the leveling length to the maximum extent, increasing the single working surface of the leveling machine, and improving the leveling efficiency; the earth-breaking mechanism can be retracted upward when retracted to ensure that the retracting action of the secondary leveling mechanism is not affected. The additional earth-breaking mechanism can ensure that the secondary leveling mechanism can not only level the soil and press the grass, but also break the soil and separate the grass, ensuring the leveling effect and grass pressing effect of the extended leveling surface;

[0031] The auxiliary leveling mechanism 4 has two states: working and storage;

[0032] In the working state: the auxiliary leveling mechanism 4 extends parallel to the two ends of the main leveling mechanism 2, the anti-collision plate 7 is in the unfolded state and is arranged horizontally, and the auxiliary earth-breaking mechanism 5 lowers the second earth-breaking plate 56;

[0033] In the retracted state: the auxiliary leveling mechanism 4 is retracted into the main leveling mechanism 2 , the anti-collision plate 7 is in an upwardly folded state and is vertically arranged with the auxiliary leveling mechanism 4 , and the auxiliary earth-breaking mechanism 5 retracts the second earth-breaking plate 56 .

[0034] like Figure 1 and Figure 2 As shown, the main leveling mechanism 2 includes a long storage box 21 and a main pressure plate 22. The long storage box 21 is a long strip with openings at both ends. The back of the long storage box 21 is connected to the lifting adjustment mechanism 1. The front panel of the long storage box 21 is provided with a notch 211 of equal length. The bottom plate of the long storage box 21 is horizontally extended with a main pressure plate 22. The bottom surface of the main pressure plate 22 is vertically spaced with a plurality of first earth-breaking plates 222.

[0035] Specifically, the storage long box has four side panels, which are, in clockwise order, a bottom panel, a back panel, a top panel, and a front panel. The back panel is connected to a lifting and adjusting mechanism. A gap is left between the front panel and the bottom panel. A main pressure plate extends outward from the bottom panel.

[0036] The auxiliary leveling mechanism 4 includes a fixed bar 41 and an auxiliary pressure plate 42. The fixed bar 41 is slidably received in the storage long box 21. The bottom plate of the fixed bar 41 is horizontally extended with an auxiliary pressure plate 42. The auxiliary pressure plate 42 is placed parallel to the top of the main pressure plate 22. The auxiliary pressure plate 42 extends outward from the notch 211. The notch 211 is used as an intake channel for the auxiliary pressure plate 42.

[0037] The design of the notch can ensure that the fixed bar is stored in the long storage box and the auxiliary pressure plate can be stored in the top surface of the main pressure plate; the length of the auxiliary pressure plate is half of the length of the main pressure plate.

[0038] like Figure 3 As shown, the auxiliary earth-breaking mechanism 5 includes a support seat 51, a second earth-breaking plate fixing frame 53, a first spring 54, a movable column 55, and a second earth-breaking plate 56; the support seat 51 is installed on the upper surface of the extended area of ​​the auxiliary pressure plate 42, and both ends of the second earth-breaking plate fixing frame 53 are extended into the support seat 51, and the installation directions of the two support seats 51 are consistent;

[0039] The support seat 51 is vertically slidably connected to the second breaking plate fixing frame 53. The bottoms of both ends of the second breaking plate fixing frame 53 are provided with first springs 54, which are installed on the surface of the auxiliary pressure plate 42. The first spring is used to push the second breaking plate fixing frame to move upward and reset to the top of the auxiliary pressure plate when the pressure is lost, so as to avoid the second breaking plate from conflicting with the main pressure plate.

[0040] The surface of the auxiliary pressure plate 42 is provided with a through hole 422, and the through hole 422 is relatively located at the bottom of the second breaking plate 56; the through hole is used as a channel for the second breaking plate to move up and down;

[0041] The second breaking plates 56 are vertically spaced apart on the bottom surface of the second breaking plate fixing frame 53. The lifting movement of the second breaking plate fixing frame 53 drives the second breaking plates 56 to move up and down.

[0042] A movable column 55 is vertically provided on the end side wall of the second earth-breaking plate fixing frame 53, and a sliding hole 511 is opened in the support seat 51 for the movable column 55 to slide through. The extended end of the movable column 55 is cooperated with a lifting drive assembly, and the lifting drive assembly is used to drive the second earth-breaking plate fixing frame 53 to move up and down through the movable column 55; the lifting drive assembly drives the movable column to move up and down, and then drives the second earth-breaking plate fixing frame to move up and down, so as to realize the automatic lowering and retracting of the second earth-breaking plate.

[0043] like Figure 3 As shown, the lifting drive assembly includes a rotating cover 52, a connecting rod 57 and a baffle 8. The rotating cover 52 is rotatably installed on the outside of the support seat 51. The rotating cover 52 is tilted toward the anti-collision plate 7. The extended end of the movable column 55 is rotatably embedded in the rotating cover 52. The rotating cover 52 is used to drive the movable column 55 to move up and down. The two ends of the connecting rod 57 are respectively rotatably connected to the top side walls of the two rotating covers 52. The baffle 8 is fixed to the side wall of the storage long box 21. The baffle 8 extends to the two rotating covers. The baffle 8 is located above the connecting rod 57 between the two rotating covers 52, and the baffle 8 is used to stop the rotating cover 52 from rotating. The baffle is placed between the two rotating covers to ensure that when the auxiliary earth-breaking mechanism and the auxiliary leveling mechanism move outward synchronously, the baffle can contact the rotating cover located on the inner side. As the auxiliary earth-breaking mechanism moves, the baffle will push the inner rotating cover to rotate, and the rotation of the inner rotating cover will drive the outer rotating cover to rotate through the connecting rod, thereby driving the movable column to move downward, so that the second earth-breaking plate fixing frame and the earth-breaking plate move downward.

[0044] The initial angle between the rotating cover 52 and the support seat 51 is 100-140°; the obtuse angle design ensures that the rotating cover in motion can be pushed and rotated, and the moving process is automatically lowered without manual operation.

[0045] like Figure 4As shown, the second hydraulic rod 3 is fixed to the top surface of the storage long box 21 through the second hydraulic rod fixing plate 212, and the baffle 8 is installed on the side wall of the second hydraulic rod fixing plate 212; the baffle is directly fixed to the second hydraulic rod fixing plate, which makes the installation of the baffle easier and there is no need to open a separate installation hole on the storage long box.

[0046] like Figure 4 and Figure 5 As shown, the fixed strip 41 is connected to the anti-collision plate 7 through a transmission mechanism 6, and the transmission mechanism 6 includes a first connecting plate 61, a second connecting plate 62, a first limiting plate 64 and a second limiting plate 65; the first limiting plate 64 is symmetrically arranged on the surface of the fixed strip 41, the bottom end of the first connecting plate 61 is rotatably connected to the first limiting plate 64, the top end of the first connecting plate 61 is rotatably connected to the end of the second connecting plate 62, the middle parts of the two first connecting plates 61 are rotatably connected to the end of the second hydraulic rod 3, the end of the first connecting plate 61 away from the first limiting plate 64 is rotatably connected to the end of the second connecting plate 62, the end of the second connecting plate 62 away from the first connecting plate 61 is rotatably connected to the middle part of the second limiting plate 65, the second limiting plate 65 is arranged on the surface of the anti-collision plate 7, and the outer walls of the first limiting plate 64 and the second limiting plate 65 are connected by a reset component;

[0047] The reset assembly includes a first pin, a second pin and a second spring. The first pin is provided at the bottom end of the outer wall of the first limiting plate 64, and the second pin is provided at one end of the outer wall of the first limiting plate 64 close to the anti-collision plate 7. One end of the second spring 63 is connected to the first pin and the other end is connected to the second pin. The rotation connection between the second connecting plate 62 and the second limiting plate 65 is located in the middle of the second limiting plate 65.

[0048] The lifting and adjusting mechanism 1 includes a fixed frame 11, a first hydraulic rod 12 and a support frame 13. The fixed frame 11 is fixedly arranged on the inner side of the storage long box 21. One end of the first hydraulic rod 12 is rotatably connected to the vehicle body, and the other end is rotatably connected to the fixed frame 11. One end of the support frame 13 is rotatably connected to the vehicle body, and the other end is rotatably connected to the fixed frame 11. The support frame 13 is located at the bottom of the first hydraulic rod 12.

[0049] A first guide groove 221 distributed in a linear array is opened at the edge of the main pressure plate 22, and a second guide groove 421 distributed in a linear array is opened at the edge of the auxiliary pressure plate 42. The guide grooves are used to spread and spread the soil; each perforation 422 is located between two second guide grooves 421.

[0050] When the present invention is implemented:

[0051] Initial state: the auxiliary leveling mechanism 4 is placed in the main leveling mechanism 2, and the anti-collision plate 7 is rotated upward and retracted to a vertical state;

[0052] Working state: the first hydraulic rod 12 pushes the main leveling mechanism 2 to rotate downward, the first breaking plate 222 of the main leveling mechanism 2 is embedded in the soil, and the main pressing plate 22 is in contact with the soil;

[0053] The second hydraulic rod 3 pushes the fixed bar 41 to move outward, and the anti-collision plate 7 follows the outward movement, the fixed bar 41 leaves the storage long box 21, and the auxiliary pressure plate 42 gradually leaves the main pressure plate 22; as the movement proceeds, the rotating cover 52 located on the inside fits with the baffle 8, and the baffle 8 pushes the rotating cover 52 to rotate clockwise, and the inner rotating cover 52 drives the other rotating cover 52 to move synchronously through the connecting rod 57; when the rotating cover 52 rotates around the support seat 51, the rotating cover 52 will drive the movable column 55 to move downward along the sliding hole 511, and the second breaking plate fixing frame 53 slides downward and compresses the first spring 54, and the downward movement of the second breaking plate fixing frame 53 will drive the second breaking plate 56 to extend downward from the through hole 422;

[0054] When the second earth-breaking plate 56 is fully extended downward, the baffle plate 8 will stop the rotating cover 52, thereby stopping the entire auxiliary earth-breaking mechanism 5 and the auxiliary leveling mechanism 4;

[0055] The second hydraulic rod 3 continues to extend outward, pushing the middle parts of the two first connecting plates 61, so that the first connecting plate assembly rotates outward, the first connecting plate 61 pushes the second connecting plate 62 to rotate outward, and the outer end of the second connecting plate 62 pushes the second limit plate 65 and the anti-collision plate 7 to rotate outward, and the anti-collision plate 7 rotates 90° to a horizontal state, and the second pin on the outer wall of the second limit plate 65 stretches the second spring 63; at this time, the anti-collision plate can be deployed;

[0056] When leveling the paddy field: the first breaking plate 222 and the second breaking plate 56 perform plowing operations and separate the grass and soil clods. After the soil and grass are broken and separated, the main pressing plate 22, the auxiliary pressing plate 42 and the anti-collision plate 7 can flatten the land.

[0057] In the non-working storage state: the second hydraulic rod 3 drives the fixed bar 41 to slide inwards and be stored in the storage long box 21, the anti-collision plate 7 and the rotating cover 52 are no longer subjected to thrust, the second spring 63 drives the anti-collision plate 7 to rotate upwards to the retracted state, the first spring 54 pushes the second breaking plate fixing frame 53 to slide upwards, and the second breaking plate 56 passes through the through hole 422 and is retracted to the top of the auxiliary pressure plate 42;

[0058] The fixed bar 41 is gradually slid into the long storage box 21, and the auxiliary pressing plate 42 is slid into the upper surface of the main pressing plate 22, so that automatic folding is achieved.
