Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and in particular to a floating control type paddy field slurry leveling machine. Background Technology

[0002] Paddy field leveling is a prerequisite for the application of irrigation, transplanting, broadcasting, and direct seeding technologies. A higher degree of leveling can increase rice yield by more than 10%. During paddy field leveling operations, traditional paddy field leveling machines are rigidly connected to tractors. A hard bottom layer can cause the paddy field leveling machine to pitch or tilt, resulting in digging or unloading of mud, reducing the machine's operating efficiency and the leveling of the paddy field, and increasing the number of leveling operations.

[0003] Chinese invention patent CN113207330B discloses a paddy field slurry leveling machine, which adjusts the level and elevation of the scraper blade through two horizontal adjustment cylinders and one height adjustment cylinder. However, due to the time delay in hydraulic control technology, machine control failure and digging issues easily occur when the machine tilts or pitches. Chinese invention patent CN114766103B discloses an automatic leveling system and method for a rotary tiller. When the ground support force is less than the weight of the rotary tiller, the force-bearing components of the automatic leveling mechanism are hydraulic columns and control modules. In this case, the rotary tiller and tractor remain rigidly connected, making automatic leveling impossible. Using the above technologies to reduce the impact of a hard subgrade on paddy field leveling operations is insufficient to achieve a high degree of paddy field flatness. A paddy field slurry leveling machine with flexible connection to the tractor and adaptive leveling capabilities is needed. Summary of the Invention

[0004] The present invention provides a floating control type paddy field slurry leveling machine to solve the problems existing in the prior art.

[0007] A further design of the floating control type paddy field slurry leveling machine is that the floating device is at least one two-bar structure, including a rotating connecting rod for adjusting the attitude of the floating device, a floating connecting rod for adjusting the amount of soil transported, a scraper plate connecting seat, a primary hydraulic cylinder, and a secondary hydraulic cylinder.

The reset unit includes a strong pressure rod, a support sleeve, two springs, and two adjusting sleeves. The support sleeve is rotatably supported on the floating connecting rod. One end of the strong pressure rod is hinged to the rotating connecting rod, and the other end passes through the support sleeve. The two adjusting sleeves are engaged with the strong pressure rods on both sides of the support sleeve. The springs are respectively sleeved on the strong pressure rods between the two adjusting sleeves and the support sleeve.

[0009] A further design feature of the floating control type paddy field slurry leveling machine is that a protective sleeve is fitted around the outer periphery of the spring.

[0010] A further design of the floating control type paddy field slurry leveling machine is that the suspension device includes a frame, lugs for connecting the surface contouring device, and two rotating sliders. The lugs are respectively located on the crossbeams on both sides of the frame. The two rotating sliders are respectively hinged to the front and rear sides of the frame relative to the forward direction of the machine body, and the rotation axis is located on the central axis of the frame. The rotating sliders are provided with grooves.

[0011] A further design of the floating control type paddy field slurry leveling machine is that the suspension device also includes a baffle, a friction plate, and a limiting block. The baffle is welded to the inner side of the bottom corner of the frame, the limiting blocks are fixed to the outer side of the bottom corner of the frame, and the friction plate is installed on one side of the baffle and abuts against the inner surface of the frame and the limiting block.

[0012] A further design of the floating control type paddy field slurry leveling machine is that the frame includes a frame crossbeam, suspension lugs, positioning rails, frame longitudinal beams, and retractable lugs.

[0013] A further design of the floating control type paddy field leveling machine is that the surface contouring device includes a buffer rod, a buffer pressure rod, an adjusting clip, and a compression spring. One end of the buffer pressure rod is hinged to the lifting lug, and the other end has a through hole for passing through the buffer rod. One end of the buffer rod passes through the through hole and is hinged to the suspension lug, and the other end is connected to the adjusting clip.

Detailed Implementation

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] like Figures 1 to 6 As shown, the floating control type paddy field slurry leveling machine of the present invention mainly consists of a suspension device 1, a frame 2, a floating device 3, a surface contouring device, a scraper blade 4, and a lifting plate 7. The suspension device 1 is hinged to the frame 2 and connected to the frame 2 through the surface contouring device. The scraper blade 4 is movably connected to the frame 2 through the floating device 3, and the lifting plate 4 is connected to the bottom end of the frame 2.

[0028] In this embodiment, the floating device 3 consists of two parallel bi-link structures arranged on the frame. For example... Figure 5 The two-bar linkage structure in this embodiment mainly consists of a rotating connecting rod 32 for adjusting the attitude of the floating device, a floating connecting rod 33 for adjusting the soil transport volume, a scraper plate connecting seat 40, a primary hydraulic cylinder 5, and a secondary hydraulic cylinder 6. The rotating connecting rod 32 is hinged to the frame 2 and connected to the frame 2 via the primary hydraulic cylinder 5. The floating connecting rod 33 is hinged to the rotating connecting rod 32; the scraper plate connecting seat 40 is fixedly connected to the scraper plate 4. One side of the scraper plate connecting seat 40 is hinged to the floating connecting rod 33, and the other side is connected to the floating connecting rod 33 via the secondary hydraulic cylinder 6. Both the rotating connecting rod 32 and the floating connecting rod 33 are irregularly shaped rods.

[0029] like Figure 6As shown, the secondary cylinder 6 causes the scraper 4 to rotate around the floating connecting rod 33, and the primary cylinder 5 causes the rotating connecting rod 32 to rotate around the fixed lifting lug 31. When the primary cylinder 5 and the secondary cylinder 6 are fully retracted, the machine body is in the transport state, and when the primary cylinder 5 is fully extended, the machine body is in the working state.

[0030] The floating device in this embodiment also includes a reset unit, see [link to relevant documentation]. Figure 5 The reset unit mainly consists of a pressure rod 34, a support sleeve 38, two springs 35, and two adjusting sleeves 37. The support sleeve 38 is rotatably supported on the floating connecting rod 33. One end of the pressure rod 34 is hinged to the rotating connecting rod 32, and the other end passes through the support sleeve 38. The two adjusting sleeves 38 are engaged with the pressure rods on both sides of the support sleeve. The springs 35 are respectively sleeved on the pressure rods between the two adjusting sleeves 37 and the support sleeve 38. The support sleeve 38 and the floating connecting rod 33 only rotate, and the support sleeve 38 and the pressure rod 34 only have relative linear motion. Under the combined action of the pressure rod 34, the springs 35, and the support sleeve 38, the floating connecting rod 33 generates a return force when rotating around the rotating connecting rod 32. The compression of the spring 35 is changed by shortening the distance between the adjusting sleeves 37 and the support sleeve 38, and the angle between the floating connecting rod 33 and the rotating connecting rod 32 is adjusted by changing the position of the two adjusting sleeves 37. In this embodiment, a protective sleeve 36 is also fitted around the outer periphery of the spring 35.

[0031] like Figure 2 and 3 The suspension device in this embodiment mainly consists of a frame 111, lugs 112 for connecting the ground contouring device, and two rotating sliders 17. The frame 111 in this embodiment is a three-point suspension structure. The lugs 112 are respectively provided on the crossbeams on both sides of the frame 111, and the two rotating sliders 17 are respectively hinged to the front and rear sides of the frame 111 relative to the forward direction of the machine body, with the rotation axis located on the central axis of the frame. The rotating sliders 17 are provided with grooves.

[0032] The suspension bracket 11 device in this embodiment also includes a baffle 113, a friction plate 114, and a limiting block 115. The baffle 113 is welded to the inner side of the bottom corner of the frame 111, and the limiting blocks 115 are respectively fixed to the outer side of the bottom corner of the frame 111. The friction plate 114 is installed on one side of the baffle 113 and abuts against the inner surface of the frame and the limiting block 115. The friction plate 114 contacts the frame crossbeam 22 to provide dry friction damping and attenuate vibration.

[0033] like Figure 4The frame in this embodiment mainly consists of a frame crossbeam 22, suspension lugs 23, positioning rails 16, frame longitudinal beams 21, extension plates 26, and retractable lugs 24. The frame crossbeams are welded to the frame longitudinal beams. The suspension lugs 23 are welded to the frame crossbeam 22 and connected to the ground contouring device. The retractable lugs 24 are welded to the frame longitudinal beams 21 and hinged to the floating device 3. The positioning rails 16 are fixed to the frame crossbeam 22 and detachably connected to the groove of the rotating slider 17, achieving the hinge connection between the suspension device and the frame. The rotating slider 17 allows the suspension frame 11 to move only vertically and rotate relative to the frame 2. The frame crossbeam 22 and the extension plate 26 are both slidably connected to the friction plate 114. The extension plate 26 increases the contact area between the friction plate 114 and the frame 2, limiting the pitching motion of the suspension frame 11 relative to the frame 2.

[0034] like Figure 2 The ground contouring device in this embodiment mainly consists of a buffer rod 12, a buffer pressure rod 13, an adjusting clip 15, and a compression spring 14. One end of the buffer pressure rod 13 is hinged to a lifting lug 112, and the other end has a through hole for the buffer rod to pass through. One end of the buffer rod 13 passes through the through hole and is hinged to the suspension lug 12, and the other end is connected to the adjusting clip 15. The compression spring 13 is sleeved on the buffer rod 12 between the adjusting clip 15 and the buffer pressure rod 13.

[0035] In this embodiment, the lifting plate 7 is an inclined structure on the side opposite to the forward direction of the aircraft body, which is used to convert drag into lift.

[0036] The working principle of this device is as follows:

[0037] This invention relates to a floating, adjustable paddy field leveling machine. The suspension device is fixed to the center of the frame and is secured to the tractor via a three-point suspension. Before operation, the position of the adjustment device needs to be determined so that the buffer spring is at the user's desired length, and the position of the adjustment parts needs to be determined so that the floating connecting rod is at the user's desired position. During operation, under the action of the buffer spring, the suspension device allows the paddy field leveling machine to float on the mud surface, enabling it to adaptively adjust its level and elevation. Under the action of the spring, the floating device adaptively adjusts the height of the scraper blade and stabilizes it in a suitable position. When a lift plate is installed, the buoyancy generated enhances the floating effect of the paddy field leveling machine. The amount of soil transported by the scraper blade is controlled by adjusting the length of the secondary hydraulic cylinder, achieving the purpose of leveling the paddy field. The transport and operation modes of the floating device are switched by adjusting the length of the primary hydraulic cylinder, facilitating the transport of the implement. This invention features a simple structure, ease of control, high reliability, and convenient transportation.

[0038] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
