Description

Technical Field

[0001] This invention relates to the field of ridging devices, and in particular to a vegetable field tillage and ridging device and its ridging method. Background Technology

[0002] The vegetable field tillage and ridging device is a combined land preparation machine for large-scale vegetable planting, which is equipped with a tractor and is used for tractor-pulverized soil preparation. It integrates rotary tillage and soil breaking, ditching and ridging, and ridge shaping and compaction functions, and completes soil tillage and ridge formation in one operation.

[0003] Existing vegetable field tillage and ridging devices mostly rely on fixed-specification shaping rollers to compact and shape the ridge surface. The overall structural dimensions of the shaping rollers are not adjustable; the outer diameter and width of the rollers are fixed values. They can only form ridges of a single specification and cannot flexibly change the ridge height, ridge width, and ridge surface curvature according to the agronomic planting needs of different vegetable varieties. If different sizes of ridges are to be processed, rollers of different specifications must be replaced as a whole, which is time-consuming and labor-intensive. The adaptability of the operation is poor, and it cannot meet the ridging requirements of rotating multiple types of vegetables. It lacks versatility and increases the cost of field operations and the time spent on the process.

[0004] Therefore, it is necessary to design a vegetable field tillage and ridging device and its ridging method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vegetable field tillage and ridging device and its ridging method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vegetable field tillage and ridging device includes a fixed frame, a movable frame rotatably mounted on the fixed frame, a cylinder mounted on the fixed frame, the telescopic end of the cylinder being rotatably connected to the movable frame, two mounting rods fixed on the fixed frame, the ends of the two mounting rods away from the fixed frame being jointly fixed to the mounting frame, the mounting frame being located directly above the movable frame, a ridge surface shaping component being provided on the movable frame, and two sliding components and two adjusting components being provided on the movable frame.

[0007] As a preferred embodiment of the present invention, the ridge shaping component includes a connecting rod, which is fixed on a movable frame. An installation ring is fixed to the end of the connecting rod away from the movable frame. A rotating cylinder is rotatably mounted on the installation ring. Sliding cylinders are slidably sleeved at both ends of the rotating cylinder. A shaping cylinder is fixed to the ends of the two sliding cylinders that are far apart from each other. The shaping cylinder has a frustum-shaped structure, and the two shaping cylinders are arranged in a mirror image. A fixing rod is fixed to each shaping cylinder.

[0008] As a preferred embodiment of the present invention, the two fixed rods, the two shaping cylinders, the two sliding cylinders, and the rotating cylinder are arranged coaxially.

[0009] As a preferred embodiment of the present invention, the inner wall of the sliding cylinder is in contact with the outer surface of the rotating cylinder.

[0010] As a preferred embodiment of the present invention, the sliding assembly includes a guide rail, the guide rail is fixed to the side of the movable frame, a slide block is slidably disposed on the guide rail, a mounting seat is fixed to the side of the slide block, a slot is provided on the side of the mounting seat, a bearing seat is fixed on the mounting seat, and the fixing rod is rotatably mounted on the bearing seat.

[0011] As a preferred embodiment of the present invention, the adjustment assembly includes a side plate, which is fixed to the side of the movable frame. The side plate has several openings, and a locking pin is inserted into one of the openings.

[0012] As a preferred embodiment of the present invention, the plurality of openings are arranged in a linear array along the length of the side plate.

[0013] As a preferred embodiment of the present invention, the mounting frame is provided with a cleaning assembly, the cleaning assembly including two vertical rods, both of which are fixed on the mounting frame, and a mounting frame is fixed to the end of each of the two vertical rods away from the mounting frame. The two mounting frames are inclined and mirror images of each other. Several rollers are rotatably mounted on each mounting frame. The cleaning assembly also includes a scraper, which is placed below the mounting frame and is fixed to the two mounting frames by two horizontal rods.

[0014] As a preferred embodiment of the present invention, the two mounting frames are respectively positioned opposite the two shaping cylinders.

[0015] A method for ridging vegetables in a field using a tillage and ridging device includes the following steps: Step 1: According to the agronomic requirements for vegetable planting, adjust the distance between the two shaping cylinders to determine the ridge size. First, pull out the locking pin of the adjusting component so that the locking pin is disengaged from the slot of the mounting base, releasing the restriction on the slide. Push the shaping cylinder to drive the fixing rod, bearing seat and slide to move along the guide rail. The guide rail and slide provide guidance to ensure that the shaping cylinder moves smoothly. After adjusting to the target size, insert the locking pin into the corresponding opening of the side plate and the slot of the mounting base to lock the position of the shaping cylinder. Step 2: Move the adjusted device to the vegetable field to be ridged, adjust the connection angle between the fixed frame and the traction machine to ensure that the ridge shaping component is aligned with the area to be ridged, start the traction machine, and drive the fixed frame and the movable frame to move slowly. The rotating cylinder, sliding cylinder and shaping cylinder on the movable frame rotate synchronously and make initial contact with the soil during the movement, laying the groundwork for ridge shaping. Step 3: The traction machinery continues to move at a constant speed. The ridge shaping component on the movable frame moves forward synchronously with the device. The rotating cylinder, sliding cylinder and shaping cylinder roll on the soil surface to compact and shape the tilled soil. The two mirror-shaped frustum-shaped shaping cylinders, together with the sliding cylinder and rotating cylinder, squeeze the soil into a regular ridge surface. During the shaping process, the cooperation between the sliding seat and the guide rail ensures that the position of the shaping cylinder is stable, ensuring that the ridge surface is uniform in size and flat, meeting the requirements for vegetable planting. Step 4: After ridging is completed, turn off the traction machine, start the cylinder, control the cylinder extension end to retract, lift the tail end of the traction frame, and drive the ridge shaping component to rise synchronously. At this time, the shaping cylinder contacts the roller on the mounting frame. Under the guidance of the inclined mounting frame, the two shaping cylinders approach each other, the sliding cylinder fits against the rotating cylinder, and the shaping cylinder, sliding cylinder and scraper contact the scraper. Rotate the shaping cylinder, the scraper scrapes off the soil attached to the surface, and the sliding cylinder scrapes off the soil on the surface of the rotating cylinder for cleaning.

[0016] The present invention has the following beneficial effects: This invention features an adjustable ridge shaping component. Through the cooperation of a sliding component and an adjusting component, the distance between the two shaping cylinders can be flexibly adjusted according to different agronomical needs of vegetable cultivation. This allows for the shaping of ridges of various sizes, breaking the limitations of traditional shaping rollers with fixed dimensions and poor versatility. It can adapt to different ridge widths without replacing any parts of the machine. The adjustment operation is simple and convenient, and the positioning and locking are reliable. During operation, it is not easily shifted by soil thrust, ensuring that the ridges are formed neatly and uniformly. The added cleaning component allows the shaping cylinders to automatically retract after the movable frame is raised, guided by an inclined mounting frame and rollers. A scraper removes soil from the surfaces of the shaping cylinders and sliding cylinders. Simultaneously, the sliding cylinder can clean the accumulated mud on the outer wall of the rotating cylinder during its sliding process, achieving automatic mud removal without disassembly and eliminating the tedious manual cleaning.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1: A vegetable field tillage and ridging device disclosed in this example, referring to... Figure 1-5 The machine includes a fixed frame 1, which serves as the main load-bearing base of the machine. The frame is made of thickened channel steel and square tube welded together, resulting in high overall structural strength and strong resistance to torsion and compression. It can adapt to complex bumpy road conditions in the field and the soil reaction force during tillage and ridging operations. A movable frame 2 is rotatably installed on the fixed frame 1. The movable frame 2 is also made of agricultural machinery special steel bent and welded together, and can be tilted and rotated at a certain angle relative to the fixed frame 1. A cylinder 3 is installed on the fixed frame 1. The cylinder 3 is an agricultural dustproof and mudproof telescopic cylinder 3, which has good sealing and protection performance. It can prevent mud, water, straw and other debris from entering the cylinder 3, ensuring that the telescopic action is sensitive and reliable. The telescopic end of the cylinder 3 is rotatably connected to the movable frame 2. When the telescopic end of the cylinder 3 retracts, it can pull the movable frame 2 to rotate, thereby controlling the tail end of the movable frame 2 to lift. The cylinder 3 is rotatably installed on the fixed frame 1. It can adaptively deflect slightly with the angle change of the movable frame 2, avoiding bending damage to the telescopic end caused by radial torque, and improving the service life and transmission stability of the cylinder 3. like Figure 1 As shown, the fixed frame 1 can be towed by agricultural drive vehicles such as tractors. The front end of the fixed frame 1 is equipped with a standard suspension connector, which can be directly matched with the rear suspension structure of common tractors. It is convenient to disassemble and connect, and is compatible with multiple models of agricultural traction machinery. It has strong versatility. The fixed frame 1 is equipped with two wheels, which facilitates the smooth movement of the fixed frame 1. During the movement, it can provide auxiliary support and smooth guidance for the whole machine. There are two mounting rods 4 fixed on the fixed frame 1. The two mounting rods 4 are jointly fixed to the mounting frame 5 at the ends away from the fixed frame 1. The mounting frame 5 is located directly above the movable frame 2. The movable frame 2 is equipped with a ridge shaping component, which includes a connecting rod 61. An installation ring 62 is fixed to the end of the connecting rod 61 away from the movable frame 2. A rotating cylinder 63 is rotatably mounted on the installation ring 62. The rotating cylinder 63 is made of seamless steel pipe and the surface is treated with anti-rust and wear-resistant treatment. The rotating cylinder 63 can rotate freely in the installation ring 62. During the rotation, it runs smoothly without jamming. The rotation connection between the installation ring 62 and the rotating cylinder 63 adopts an embedded bearing limiting structure. As prior art, it is not shown in the figure and will not be described in detail here. Both ends of the rotating cylinder 63 are slidably fitted with sliding cylinders 64. The inner diameter of the sliding cylinder 64 is precisely matched with the outer diameter of the rotating cylinder 63. The gap is moderate, which can slide smoothly along the axial direction of the rotating cylinder 63 without shaking, tilting or offset. It has good sealing performance and can reduce the entry of mud and sand into the fitting gap and cause jamming and wear. Two sliding cylinders 64 are each fixed with a shaping cylinder 65 at their far ends. The shaping cylinder 65 has a frustum-shaped structure and is made of wear-resistant cast steel in one piece. Its outer surface is smooth and rounded, making it difficult for wet clay to adhere. It also has strong compressive and deformation resistance. The two shaping cylinders 65 are set up in a mirror symmetrical manner. During operation, they work together to gather and compress the soil on both sides, naturally forming a standard trapezoidal ridge outline, which is suitable for the ridge cross-section requirements of various vegetable plantings. Each shaping cylinder 65 is fixed with a fixing rod 66. When using the ridging device proposed in this invention, the fixed frame 1 is securely suspended at the tail of the agricultural traction machinery through a suspension structure. After the connection and installation are secure, the device can be put into field operation after adjusting the level and working height. The fixed frame 1 moves forward at a uniform speed under the drive of the traction machinery, and simultaneously drives the movable frame 2 to move forward as a whole. The two shaping cylinders 65, the two sliding cylinders 64 and the rotating cylinder 63 on the movable frame 2 roll synchronously to the ground, and cooperate with each other to squeeze, gather, level and compact the soil after tillage, and complete the rapid shaping operation of the ridge surface. The ridging and shaping process after tillage is completed in one go, without the need for secondary manual trimming. The movable frame 2 is symmetrically equipped with two sliding components and two adjusting components. The left and right sets of structures are completely symmetrical, and the distance between the two shaping cylinders 65 can be adjusted synchronously to ensure that the ridge is centered, symmetrical, and well-formed. The sliding components include a guide rail 71, which is horizontally fixed to the side of the movable frame 2 by bolts. A slide block 72 is slidably mounted on the guide rail 71. A mounting seat 73 is fixed to the side of the slide block 72. A slot 74 is opened on the side of the mounting seat 73. A bearing seat 75 is fixed on the mounting seat 73. The fixing rod 66 is rotatably mounted on the shaft. On the support 75, the adjustment component includes a side plate 81, on which a plurality of openings 82 are provided. The plurality of openings 82 are evenly distributed in a linear array along the length of the side plate 81. The openings 82 have uniform diameter and regular spacing, and can provide multiple position adjustment points to adapt to the adjustment requirements of different ridge widths. A locking pin 83 is inserted into one of the openings 82. The locking pin 83 is inserted into the slot 74 of the mounting base 73 to lock the position of the sliding base 72 and the mounting base 73, preventing displacement due to soil thrust during operation. When using the ridging device proposed in this invention, the operator can flexibly adjust the distance between the two shaping cylinders 65 according to the planting row spacing and ridge width agronomic requirements of different vegetable varieties, thereby precisely changing the overall width and ridge specifications of the formed ridge surface. Specifically, during adjustment, the operator first manually pulls out the locking pin 83, completely disengaging it from the slot 74 on the side of the mounting base 73, releasing the positional constraints on the slide block 72 and the mounting base 73. After the locking pin 83 is removed, the slide block 72 can move freely and smoothly along the length of the guide rail 71. Then, the operator manually pushes... The shaping cylinder 65 is moved laterally. When the shaping cylinder 65 moves, the fixing rod 66 is moved synchronously, which in turn causes the bearing seat 75 and the mounting seat 73 to slide synchronously with the slide 72. During the entire process of the shaping cylinder 65 moving, the guide rail 71 and the slide 72 form a reliable linear guide, which effectively ensures the levelness and stability of the shaping cylinder 65 during the movement process and prevents skewness or offset. The array of several openings 82 on the side plate 81 can correspond to different ridge widths, making it convenient to accurately fix the shaping cylinder 65 at different spacing positions. The adjustment position is clear and the positioning is accurate. After adjusting the distance between the two shaping cylinders 65 and the size of the ridge surface, the workers reinsert the locking pin 83 into the corresponding opening 82 of the side plate 81, and precisely insert its lower end into the slot 74 of the mounting base 73. The mounting base 73 and the sliding base 72 are rigidly positioned by the insertion limiting structure of the locking pin 83. When the distance between the two shaping cylinders 65 changes, the width of the ridge surface and the curvature of the ridge formed by the two shaping cylinders 65 change synchronously with the linkage and adaptation of the middle rotating cylinder 63 and the sliding cylinder 64. This can adapt to the field ridging needs of various types of vegetables and greatly improve the versatility. Example 2: Based on Example 1, this example discloses a vegetable field tillage and ridging device, referring to... Figure 6-7The mounting frame 5 is equipped with a cleaning component, which is integrated and arranged below the mounting frame 5 and corresponds to the ridge shaping component. It does not require additional field operation space and has a compact and reasonable structure. It can automatically clean the shaping component without disassembling the whole machine, saving the tedious manual cleaning process. The cleaning assembly includes two vertical rods 91, which are vertically fixed to both sides of the bottom surface of the mounting frame 5. A mounting frame 92 is fixed to the end of each vertical rod 91 furthest from the mounting frame 5. The two mounting frames 92 are inclined to precisely guide the two shaping cylinders 65 to converge towards the center. The two mounting frames 92 are mirror images of each other, and several rollers 93 are rotatably mounted on each frame 92. The cleaning assembly also includes a scraper 94 made of wear-resistant, high-hardness rubber. The scraper 94 is tough, wear-resistant, and does not damage the equipment surface. It effectively scrapes away wet clay and hardened soil without easily damaging the anti-corrosion surface of the shaping cylinder 65. The scraper 94 is horizontally positioned below the mounting frame 5, directly opposite the converged rotating cylinder 63, sliding cylinder 64, and shaping cylinder 65. The scraper 94 is fixed to the two mounting frames 92 by two horizontal rods 95. The ridging device proposed in this invention also has the function of automatically cleaning the soil on the surface of the shaping cylinder 65 and the rotating cylinder 63. The working environment of vegetable fields is mostly wet clay and loam. During the ridging process, the wet soil is very easy to adhere and accumulate on the outer surface of the shaping cylinder 65, the sliding cylinder 64 and the rotating cylinder 63. If it is not cleaned in time, it will cause uneven ridge formation and deviation of ridge width. Traditional methods mostly rely on manual scraping and cleaning after the machine stops, which is time-consuming, labor-intensive, inefficient and can easily delay the farming season. When the device finishes operation or when the machine stops at the edge of the field and soil needs to be cleaned, the staff only needs to start the cylinder 3. Using the retraction traction of the telescopic end of the cylinder 3, the tail end of the movable frame 2 is controlled to be raised smoothly upward. At the same time as the movable frame 2 rotates in pitch, the ridge shaping component on it is raised synchronously and moved as a whole into the corresponding area of ​​the cleaning station. When the tail end of the movable frame 2 is raised to the set height position, the two shaping cylinders 65, the two sliding cylinders 64 and the middle rotating cylinder 63 will rise synchronously and move slightly. During this movement, the outer circular surfaces of the two shaping cylinders 65 will flexibly contact the rollers 93 arranged on the two mounting frames 92 respectively. Since the two mounting frames 92 are fixedly inclined, the two shaping cylinders 65 will be gradually guided to move closer to each other and pull together, synchronously driving the two inner sliding cylinders 64 to slide towards each other along the axis of the rotating cylinder 63 until the inner end faces of the two sliding cylinders 64 are precisely fitted and limited to the outer end faces of the mounting ring 62. At this time, the two sliding cylinders 64 reach the minimum distance state, and the distance between the two shaping cylinders 65 also shrinks to the minimum position. In this limited position, the lower outer surfaces of the two shaping cylinders 65, the two sliding cylinders 64, and the intermediate rotating cylinder 63 simultaneously come into contact with the scraper strip 94 fixedly arranged below, forming a stable scraping engagement position, such as... Figure 6 As shown in the corresponding state, the staff then manually and slowly controlled the two shaping cylinders 65 to rotate in place. During the rotation, the outer surface of the two shaping cylinders 65 and the scraper 94 slide relative to each other. The scraper 94 can continuously scrape off the hardened soil and wet clay adhering to the outer surface of the two shaping cylinders 65 and the two sliding cylinders 64, quickly realizing automatic surface cleaning. It is worth noting that the inner wall of the sliding cylinder 64 is precisely fitted to the outer surface of the rotating cylinder 63, with minimal gap and smooth fit. During the axial sliding process of the two sliding cylinders 64, the inner wall of the sliding cylinder 64 can simultaneously form a radial scraping on the outer surface of the rotating cylinder 63, which can simultaneously scrape off the dirt adhering to the surface of the rotating cylinder 63, and complete the internal cleaning of the rotating cylinder 63. The cleaning range is comprehensive and without dead corners, eliminating the need for manual cleaning of each component. In addition, the roller 93 can rotate freely, which can transform the hard sliding friction between the shaping cylinder 65 and the mounting frame 92 during the movement and retraction into rolling friction, greatly reducing the contact friction force and reducing wear and tear between components. At the same time, it makes the retraction process of the shaping cylinder 65 smoother and more stable, without jamming or hard collisions, making it easy for operators to manually control the slow rotation of the shaping cylinder 65 to complete the fully automatic mud cleaning operation, saving time and labor, and improving the convenience and service life of the whole machine.
