Description

Technical Field

[0001] This invention relates to the field of agricultural tillage machinery technology, and more specifically, to a concave ridge forming device and ridge forming method for a ridger. Background Technology

[0002] In the "double-row per ridge" high-yield cultivation model for crops such as corn and potatoes, ridging machines are typically used for tillage. Currently, most mainstream ridging machines (whether tractor-mounted or suspended) use simple, flat scrapers to form ridges with flat tops after operation. This type of ridge has significant drawbacks: First, the effective width of the ridge is limited, hindering the expansion of growth space for the double-row crops and easily leading to overcrowding. Second, after several washes by rainwater, the flat-topped ridge easily forms a convex ridge, which, during rain or irrigation, can easily wash applied fertilizer down the ridge slope into the furrows, causing nutrient loss, environmental pollution, and reduced fertilizer utilization. Third, while increasing the overall ridge width can alleviate this, it increases power consumption and soil usage. Ridging machines with special, complex structures are expensive and unsuitable for ordinary farmers. Therefore, we propose a concave ridge-forming device and ridging method for ridging machines. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a concave ridge forming device and a ridge forming method for a ridger, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a concave ridge forming device and ridge forming method for a ridge forming machine, comprising a scraper, a connecting groove at one end of the scraper, a plurality of positioning components connected inside the connecting groove, a ridge blank component installed at the bottom of each positioning component, a mounting seat installed at the top of the scraper, a measuring ruler installed on the front side of the mounting seat, and a plurality of equidistant positioning grooves opened on the rear side of the mounting seat.

[0005] The ridge assembly includes a wedge plate installed at the bottom of the positioning assembly. The front side of the wedge plate has a front end plane, the rear side of the wedge plate has a rear end elevation, the top of the wedge plate has a top slope, and both ends of the wedge plate have curved surfaces.

[0006] Preferably, the positioning component includes a connecting seat connected inside the connecting groove, a mounting plate mounted on the top of the connecting seat, and a fixing seat mounted on the outer side of the mounting plate.

[0007] Preferably, two symmetrical guide posts are installed inside the fixing base, and a spring is installed on one side of the inside of the fixing base.

[0008] Preferably, a sliding plate is fitted around the outside of the two guide posts, one end of the spring is connected to the sliding plate, a positioning block is installed on one side of the sliding plate, and a connecting rod is installed on the other side of the sliding plate. The positioning block is adapted to the positioning groove.

[0009] Preferably, a pull plate is installed at one end of the connecting rod, which extends through and to the outside of the fixed seat, and a sealing ring is provided at the connection between the fixed seat and the sealing ring.

[0010] Preferably, a connecting bracket is installed on the top of the mounting plate, and a guide plate is installed at one end of the connecting bracket, with the guide plate located in front of the measuring tape.

[0011] Preferably, the front end of the wedge plate is thinner and gradually thickens towards the rear, with the highest point pointing towards the rear, for plowing grooves in the ridge soil.

[0012] Preferably, it includes the following steps:

[0013] Step 1: Fix the positioning component to the connecting groove at one end of the scraper using the connecting seat, ensuring a secure connection. Install the ridge component at the bottom of each positioning component. Specifically, install the wedge plate at the bottom of the positioning component, ensuring that the front plane, rear vertical surface, top sloping surface, and two curved surfaces of the wedge plate are set correctly so that it can be effectively shaped when moving in the soil. Install the mounting seat on the top of the scraper, and install a measuring ruler on the front side of the mounting seat. Open several sets of equidistant positioning grooves on the rear side to adjust the position of the ridge component later.

[0014] Step 2: According to the actual operation requirements, pull the pull plate to drive the slide plate to compress the spring, so that the positioning block is disengaged from the current positioning slot. Move the positioning component to a new position, so that the positioning block is aligned with the new positioning slot. Release the pull plate, the spring returns to its deformation, and pushes the slide plate to slide along the guide post. The positioning block then enters the new positioning slot to fix the position of the ridge component. Use a ruler and guide plate to make precise measurements and positioning to ensure that the ridge component is adjusted to the required position.

[0015] Step 3: Attach the ridging machine with the concave ridge forming device to the tractor, ensuring a secure and reliable connection. Adjust the tillage depth of the ridging machine to the appropriate value according to the crop type and cultivation mode.

[0016] Step 4: Start the tractor to pull the ridging machine forward. The plowshare turns over the soil and pushes it towards the center to form a preliminary ridge. As the ridging machine continues to move forward, the ridge passes the scraper and the ridge assembly installed in the middle. At this time, the wedge plate begins to play its role. The front end of the wedge plate is thinner, which can easily cut into the soil and reduce resistance. As the wedge plate gradually goes deeper, its rear end gradually thickens and is designed to be offset towards the rear to form a groove in the soil. The sloping design on the top surface is used to deepen the depth of the groove. At the same time, the rear vertical and curved surfaces ensure that the soil can transition smoothly during the movement of the wedge plate.

[0017] Step 5: Under the action of the wedge plate, the soil in the middle of the top of the ridge is pressed down or diverted to form a groove; at the same time, the scraper is used to level the whole surface. Under the combined action of the overall leveling by the scraper and the local downward pressure of the wedge plate, a flat or concave ridge surface with a central groove is formed on the top of the ridge.

[0018] Step Six: If the ridging effect is not ideal or needs to be adapted to different plots and operating conditions during the operation, the position of the ridging component can be adjusted again. Repeat the positioning component adjustment process in Step Two, adjust the ridging component to the new position, and continue ridging operation.

[0019] The technical effects and advantages of this invention are as follows:

[0020] 1. In terms of optimizing the crop growth environment, the concave ridge surface formed by this invention effectively increases the usable width of the ridge surface, providing ample space for the high-yield cultivation model of "two rows on one ridge." The two rows of crops are no longer crowded, each crop can receive sufficient sunlight for efficient photosynthesis, and ventilation is greatly improved, reducing the probability of pests and diseases and creating favorable conditions for healthy crop growth, thereby improving crop yield and quality. In terms of water and fertilizer utilization and cost control, the central groove or flat area of ​​the concave ridge surface has a strong water storage capacity, which can effectively intercept and contain rainwater or irrigation water, reduce water runoff loss, and allow water to fully penetrate into the soil, providing a stable water supply for crops. At the same time, it avoids the problem of fertilizer loss under water erosion of traditional flat-topped ridge surfaces, reduces nutrient waste, improves fertilizer utilization, and reduces fertilizer use costs. In addition, compared with improving ridge surface performance by increasing the overall ridge width, this invention does not require excessive ridge width, reducing power consumption and soil occupation, and improving energy and land use efficiency.

[0021] 2. In use, the concave ridge forming device of this invention has the function of flexibly adjusting the position of the ridge components, which can well adapt to the needs of different plots and operating conditions. The positioning component and the positioning groove on the scraper cooperate with each other. By pulling the pull plate, the sliding plate is driven to compress the spring, so that the positioning block is disengaged from the current positioning groove, and the positioning component can be easily moved to a new position. Then, the pull plate is released, the spring returns to its deformation and pushes the positioning block into the new positioning groove, thus fixing the position of the ridge components. The measuring ruler and guide plate on the front of the mounting base can perform precise measurement and positioning to ensure the accuracy of adjustment. By flexibly adjusting the position of the ridge components, this invention can accurately shape the ridge shape and size to meet the needs of crop growth according to the actual situation, providing ideal conditions for crop root growth and above-ground development, fully demonstrating its adaptability and practicality in actual agricultural production.

[0034] The positioning component 3 includes a connecting seat 31 connected inside the connecting groove 2. A mounting plate 32 is installed on the top of the connecting seat 31. A fixing seat 33 is installed on the outer side of the mounting plate 32. Two symmetrical guide posts 34 are installed inside the fixing seat 33. A spring 35 is installed on the inner side of the fixing seat 33. A sliding plate 36 is fitted on the outside of the two guide posts 34. One end of the spring 35 is connected to the sliding plate 36. A positioning block 37 is installed on one side of the sliding plate 36. A connecting rod 38 is installed on the other side of the sliding plate 36. The positioning block 37 is adapted to the positioning groove 7. A pull plate 39 is installed on one end of the connecting rod 38 through and extending to the outside of the fixing seat 33. A sealing ring 310 is provided at the connection between the fixing seat 33 and the sealing ring 310. A connecting frame 311 is installed on the top of the mounting plate 32. A guide plate 312 is installed on one end of the connecting frame 311. The guide plate 312 is located in front of the measuring ruler 6.

[0035] Includes the following steps:

[0036] Step 1: Fix the positioning component 3 inside the connecting groove 2 at one end of the scraper 1 through the connecting seat 31 to ensure a stable connection. Install the ridge component 4 at the bottom of each positioning component 3. Specifically, install the wedge plate 41 at the bottom of the positioning component 3. Ensure that the front plane 42, rear vertical surface 43, top inclined surface 44 and two curved surfaces 45 of the wedge plate 41 are set correctly so that it can be effectively shaped when moving in the soil. Install the mounting seat 5 on the top of the scraper 1, and install the measuring ruler 6 on the front side of the mounting seat 5. Open several sets of equidistant positioning grooves 7 on the rear side to adjust the position of the ridge component 4 later.

[0037] Step 2: According to the actual operation requirements, pull the pull plate 39 to drive the slide plate 36 to compress the spring 35, so that the positioning block 37 is disengaged from the current positioning groove 7, move the positioning component 3 to the new position, so that the positioning block 37 is aligned with the new positioning groove 7, release the pull plate 39, the spring 35 returns to its deformation, push the slide plate 36 to slide along the guide post 34, and the positioning block 37 enters the new positioning groove 7 to fix the position of the ridge component 4. Use the measuring ruler 6 and the guide plate 312 to make precise measurements and positioning to ensure that the ridge component 4 is adjusted to the required position.

[0038] Step 3: Attach the ridging machine with the concave ridge forming device to the tractor, ensuring a secure and reliable connection. Adjust the tillage depth of the ridging machine to the appropriate value according to the crop type and cultivation mode.

[0039] Step 4: Start the tractor and pull the ridging machine forward. The plowshare turns over the soil and pushes it towards the center to form a preliminary ridge. As the ridging machine continues to move forward, the ridge passes the scraper 1 and the ridge assembly 4 installed in the middle. At this time, the wedge plate 41 begins to play its role. The front end of the wedge plate 41 is thinner, which can easily cut into the soil and reduce resistance. As the wedge plate 41 gradually goes deeper, its rear end gradually thickens and is designed to be biased towards the rear to form a groove in the soil. The design of the top sloping surface 44 is used to deepen the depth of the groove. At the same time, the rear vertical surface 43 and curved surface 45 ensure that the soil can smoothly transition during the movement of the wedge plate 41.

[0040] Step 5: Under the action of the wedge plate 41, the soil in the middle of the top of the ridge is pressed down or diverted to form a groove; at the same time, the scraper 1 is used to level the whole surface. Under the combined action of the overall leveling by the scraper 1 and the local downward pressure of the wedge plate 41, a flat or concave ridge surface with a central groove is formed on the top of the ridge.

[0041] Step 6: If the ridging effect is not ideal or needs to be adapted to different plots and operating conditions during the operation, the position of the ridging component 4 can be adjusted again. Repeat the adjustment process of the positioning component 3 in Step 2, adjust the ridging component 4 to the new position, and continue ridging operation.

[0042] The scraper 1 serves as the main structure, with a connecting groove 2 at one end for installing and fixing multiple positioning components 3; each positioning component 3 is connected to a ridge component 4 at its bottom, which is responsible for the actual ridge surface forming work; the mounting base 5 is fixed to the top of the scraper 1, with a measuring ruler 6 installed on the front side for measurement and positioning, and several sets of equally spaced positioning grooves 7 on the rear side, which cooperate with the positioning blocks 37 on the positioning component 3 to realize the position adjustment of the ridge component 4;

[0043] Under the action of the wedge plate 41, the soil in the middle of the top of the ridge is pressed down or diverted to form a groove; at the same time, the overall leveling action of the scraper 1 ensures that the ridge surface is flat; under the combined action of the overall leveling of the scraper 1 and the local downward pressure of the wedge plate 41, the top of the ridge surface is flat or has a concave ridge surface with a central groove. This ridge surface design effectively increases the usable width of the ridge surface, providing more ample growing space for double-row crops; at the same time, the central groove or flat area can effectively intercept and contain rainwater or irrigation water, reduce runoff, and improve water and fertilizer utilization.

[0044] Working principle of the invention: The positioning component 3 is fixed inside the connecting groove 2 by the connecting seat 31. The top of the connecting seat 31 is equipped with a mounting plate 32. A fixing seat 33 is installed on one side of the mounting plate 32. Two symmetrical guide posts 34 and a spring 35 on one side are installed inside the fixing seat 33. The two guide posts 34 are fitted together with a sliding plate 36. The sliding plate 36 can only slide in a straight line under the constraint of the guide posts 34. A positioning block 37 is installed on one side of the sliding plate 36 and a connecting rod 38 is installed on the other side. One end of the connecting rod 38 passes through and extends to the outside of the fixing seat 33, and a pull plate 39 is installed. By pulling the pull plate 39, the sliding plate 36 can be driven to compress the spring 35 and slide along the guide post 34, thereby causing the positioning block 37 to disengage from or enter the positioning groove 7.

[0045] The ridge assembly 4 is the core part of the concave ridge surface forming device. Its design is ingenious and its function is clear. It mainly uses the special shape and structural features of the wedge plate 41 to precisely shape the soil during the ridge forming process and form a concave ridge surface that meets the requirements.

[0046] The wedge plate 41 is the main working component of the ridge assembly 4. Its front end is thinner and gradually thickens towards the rear, with the highest point biased towards the rear. This design allows the wedge plate 41 to gradually penetrate the soil as it moves through the soil, reducing initial resistance and generating sufficient downward pressure during subsequent movement. The front side of the wedge plate 41 is provided with a front plane 42, the rear side is provided with a rear vertical surface 43, the top is provided with a top inclined surface 44, and both ends are provided with curved surfaces 45. These surfaces work together to ensure that the wedge plate 41 can smoothly and effectively shape the soil as it moves through the soil.

[0047] As the ridging machine moves forward, the plowshare turns up the soil and pushes it towards the center to form a preliminary ridge. As the ridging machine continues to move forward, the ridge passes the scraper 1 and the ridge assembly 4 installed in the middle. At this time, the wedge plate 41 begins to play its role. Because its front end is thinner, it can easily cut into the soil and reduce resistance. As the wedge plate 41 gradually goes deeper, its rear end gradually thickens and is designed to be biased towards the rear, thus plowing out grooves in the soil. The design of the top inclined surface 44 makes the wedge plate 41 generate a downward component force on the soil as it goes deeper into the soil, further deepening the groove. At the same time, the rear vertical surface 43 and curved surface 45 ensure that the soil can transition smoothly during the movement of the wedge plate 41, avoiding soil accumulation or collapse.

[0048] Under the action of the wedge plate 41, the soil in the middle of the top of the ridge is pressed down or diverted to form a groove. At the same time, the overall leveling action of the scraper 1 ensures that the ridge surface is flat. Finally, under the combined action of the overall leveling of the scraper 1 and the local downward pressure of the wedge plate 41, a flat or concave ridge surface with a central groove is formed at the top of the ridge. This ridge surface design effectively increases the usable width of the ridge surface, providing more ample growing space for double-row crops. At the same time, the central groove or flat area can effectively intercept and contain rainwater or irrigation water, reduce runoff, and improve water and fertilizer utilization.

[0049] When the position of the ridge assembly 4 needs to be adjusted, first pull the pull plate 39 to compress the spring 35 with the slide plate 36. The positioning block 37 then disengages from the current positioning groove 7. Then, move the positioning assembly 3 to a new position so that the positioning block 37 aligns with the new positioning groove 7. Release the pull plate 39, and the spring 35 returns to its original shape, pushing the slide plate 36 to slide along the guide post 34. The positioning block 37 then enters the new positioning groove 7, thus fixing the position of the ridge assembly 4. The measuring scale 6 installed on the front side of the mounting base 5 is used to measure and display the moving distance of the ridge assembly 4 to ensure the accuracy of the adjustment. One end of the connecting bracket 311 installed on the top of the mounting plate 32 is connected to the guide plate 312. The guide plate 312 is located in front of the measuring scale 6 and is used to indicate and confirm the current position of the ridge assembly 4, making it convenient for the operator to make adjustments.

[0050] Before actual operation, the position of the ridge assembly 4 is adjusted by pulling the pull plate 39 according to the needs of crop type and cultivation mode. The measuring ruler 6 and guide plate 312 are used for precise measurement and positioning. After adjustment, the ridger is attached to the tractor, the tillage depth is adjusted to the appropriate value, and the ridge operation begins.

[0051] The plow turns the soil up and pushes it towards the center to form a ridge. When the ridge passes the scraper 1 and the ridge assembly 4 in the middle, the wedge plate 41 exerts downward pressure or diversion on the soil in the middle of the top of the ridge, forming a concave ridge surface with a flat top or a central groove. During the operation, the position of the ridge assembly 4 can be adjusted again as needed to adapt to the needs of different plots and operating conditions.

[0052] Finally, the following points should be noted: First, in the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can refer to mechanical connection or electrical connection, or internal connection between two components, or direct connection.
