Description

Technical Field

[0001] This utility model relates to the field of ridging mechanism technology, and in particular to the ridging mechanism of a greenhouse ridging and film laying machine. Background Technology

[0002] The ridging and film-laying machine is an agricultural machine that integrates ridging and film-laying functions. It is mainly used for mulching operations in farmland and is widely used in the planting of crops such as vegetables, cotton, corn, and peanuts. It can complete ridging, shaping, film-laying, and film-pressing processes in one go, greatly improving work efficiency and saving labor costs. The ridging and film-laying machine is not only suitable for outdoor agricultural planting, but also for ridging and film-laying in greenhouses.

[0003] Patent document CN219395446U discloses a ridging mechanism and a ridging machine, including a frame with a ridging surface leveling component. The ridging surface leveling component includes two opposing ridging scrapers and a ridging pressure plate on the ridging scrapers. The ridging scrapers and the ridging pressure plate are joined to form a channel for soil crushing. This invention can quickly advance and compress, causing the crushed soil to be ridged into a ridging shape. The crushed soil is not easily scattered and can also be prevented from being over-compacted, thus meeting the growth needs of crops. During the ridging process, the invention guides the crushed soil into the channel formed by the ridging pressure plate and the ridging scrapers through a guide structure, forming furrows between adjacent ridgings, thus saving working time. This invention has a simple structure and is easy to operate. The connecting plate can smooth the surface of the furrows formed after the spikes are broken, eliminating the need for subsequent manual leveling, thereby improving work efficiency.

[0004] The above solution is a one-piece welded structure. The tractor moves and drags the plow blades of the ridging mechanism to rid the field. However, it lacks a mechanism to adjust the spacing of the plow blades during use, which means it cannot adjust the ridging spacing according to the required ridging width, thus having certain limitations. Utility Model Content

[0005] This utility model discloses a ridging mechanism for a greenhouse ridging and film-laying machine, aiming to solve the technical problem that existing ridging mechanisms cannot adjust the width and depth of the ridging as needed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The ridging mechanism of the greenhouse ridging and film laying machine includes an installation frame, two symmetrical plows are set below the installation frame, a spacing adjustment mechanism is set between the installation frame and the plows, and a smoothing mechanism and a depth adjustment mechanism are set on the front and back of the installation frame, respectively.

[0008] The spacing adjustment mechanism includes a first motor fixedly installed on the right end of the mounting frame. The output shaft of the first motor extends into the interior of the mounting frame and is fixedly connected to a bidirectional threaded rod. Two symmetrical threaded blocks are threadedly connected to the surface of the bidirectional threaded rod. The front sides of the two threaded blocks are fixedly connected to two plowshares respectively through a connecting frame.

[0009] In a preferred embodiment, both the upper and lower surfaces of the threaded block are provided with guide sliders, and the inner top and bottom walls of the mounting frame are provided with guide grooves for the guide sliders to slide.

[0010] By setting a guide slider, the two threaded blocks can move relative to each other or in opposite directions under the guidance of the guide slider through the rotation of the bidirectional threaded rod.

[0011] In a preferred embodiment, the smoothing mechanism includes a connecting plate fixedly connected to the front of the mounting frame, a second motor fixedly mounted on the upper surface of the connecting plate, the output shaft of the second motor extending to the lower surface of the connecting plate and fixedly connected to a lead screw, and a scraper threadedly connected to the surface of the lead screw.

[0012] The scraper can be used to smooth the surface of the ridges after ridging.

[0013] In a preferred embodiment, the surface of the connecting plate has two symmetrical sliding slots, the upper surface of the scraper is fixedly connected to a limiting strip through the sliding slots, and a power supply box is embedded in the upper surface of the connecting plate and the mounting frame.

[0014] By setting a limiting plate, the scraper can move up and down in a directional manner through the rotation of the screw, and the leveling height can be adjusted.

[0015] In a preferred embodiment, the depth adjustment mechanism includes a mounting plate fixedly mounted on the back of the mounting frame. A vertical groove is formed through the surface of the mounting plate. A third motor is fixedly mounted on the upper surface of the mounting plate. The output shaft of the third motor extends into the interior of the vertical groove and is fixedly connected to a screw. A moving block is threadedly connected to the surface of the screw, and the moving block is fixedly connected to the back of the mounting frame.

[0016] In a preferred embodiment, limit sliders are provided on both sides of the moving block, and limit grooves for the limit sliders to slide are provided on both sides of the inner wall of the vertical groove.

[0017] By setting a limit slider, the moving block can be guided by the rotation of the screw to drive the mounting frame to move up and down in a directional manner. The depth of the grooves dug by the two plowshares can be adjusted by the up and down movement of the mounting frame.

[0018] In a preferred embodiment, two symmetrical connecting arms are fixedly mounted on the back of the mounting plate, and the surface of the connecting arms is provided with a through-hole for mounting.

[0019] The ridging mechanism can be assembled with external tractor equipment by means of the connecting arm and mounting slot.

[0020] As can be seen from the above, the ridging mechanism of the greenhouse ridging and film laying machine provided by this utility model has the following technical effects.

[0021] Firstly, when the width of the ridge needs to be adjusted, the operation of the first motor drives the bidirectional threaded rod to rotate. Under the guidance of the guide slider, the two threaded blocks can drive the two plows to move relative to or in opposite directions through the rotation of the bidirectional threaded rod. This allows the ridge-making mechanism to adjust the distance between the two plows according to the required ridge width, thus improving its practicality.

[0022] Secondly, the depth of the furrow dug by the plow can be controlled by the height of the moving block that drives the mounting frame and the plow head to move up and down. At the same time, the second motor drives the lead screw to rotate. Under the guidance of the limit plate, the scraper can move up and down in a directional manner through the rotation of the lead screw. After adjusting the furrow depth, the smoothing height of the scraper can be adjusted, which further improves the practicality of the ridging mechanism. Attached Figure Description

[0030] The spacing adjustment mechanism includes a first motor 3 fixedly installed on the right end of the mounting frame 1. The output shaft of the first motor 3 extends into the interior of the mounting frame 1 and is fixedly connected to a bidirectional threaded rod 4. Two symmetrical threaded blocks 5 are threadedly connected to the surface of the bidirectional threaded rod 4. The front sides of the two threaded blocks 5 are fixedly connected to the two plowshares 2 respectively through a connecting frame.

[0031] Guide sliders 6 are provided on both the upper and lower surfaces of the threaded block 5. Guide grooves for sliding the guide sliders 6 are provided on the inner top and bottom walls of the mounting frame 1. Under the guidance of the guide sliders 6, the two threaded blocks 5 can move relative to each other or in opposite directions by rotating the bidirectional threaded rod 4.

[0032] Reference Figure 1 and Figure 4 In a preferred embodiment, the smoothing mechanism includes a connecting plate 7 fixedly connected to the front of the mounting frame 1. A second motor 8 is fixedly mounted on the upper surface of the connecting plate 7. The output shaft of the second motor 8 extends to the lower surface of the connecting plate 7 and is fixedly connected to a lead screw 9. A scraper 10 is threadedly connected to the surface of the lead screw 9. By setting the scraper 10, the ridge surface after ridging can be smoothed. After smoothing, the ridge surface can be covered with film by an additional film covering mechanism.

[0033] The surface of the connecting plate 7 has two symmetrical sliding slots. The upper surface of the scraper 10 is fixedly connected to the limiting plate 11 through the sliding slots. The upper surface of the connecting plate 7 and the mounting frame 1 is embedded with the power box 12. Under the limiting action of the limiting plate 11, the scraper 10 can move up and down in a directional direction by rotating the screw 9 to adjust its smoothing height position.

[0034] Reference Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the depth adjustment mechanism includes a mounting plate 13 fixedly mounted on the back of the mounting frame 1. A vertical groove is opened through the surface of the mounting plate 13. A third motor 14 is fixedly mounted on the upper surface of the mounting plate 13. The output shaft of the third motor 14 extends into the interior of the vertical groove and is fixedly connected to a screw 15. A moving block 16 is threadedly connected to the surface of the screw 15. The moving block 16 is fixedly connected to the back of the mounting frame 1.

[0035] Limiting sliders 17 are provided on both sides of the moving block 16, and limiting grooves for the sliding of the limiting sliders 17 are provided on both sides of the vertical groove.

[0036] Under the guidance of the limit slider 17, the moving block 16 can drive the mounting frame 1 to move up and down in a directional manner through the rotation of the screw 15, and the depth of the groove dug by the two plows 2 can be adjusted by the up and down movement of the mounting frame 1.

[0037] Two symmetrical connecting arms 18 are fixedly installed on the back of the mounting plate 13. The surface of the connecting arms 18 is provided with a mounting slot. Through the setting of the connecting arms 18 and the mounting slot, the ridging mechanism can be assembled with external tractor equipment.

[0038] Working principle: The device is assembled and connected to an external tractor via connecting arm 18. When ridging and mulching are required inside the greenhouse, the third motor 14 drives the screw 15 to rotate. The moving block 16, through the rotation of the screw 15, moves the mounting frame 1 downward. The downward movement of the mounting frame 1 causes the two plows 2 to insert into the soil. At this time, the tractor's operation drives the plows 2 to dig trenches and furrows in the field to achieve ridging. Under the action of scraper 10, the ridge surface is smoothed. During this process, the depth of the trenches dug by the plows 2 can be controlled by the height of the moving block 16 moving the mounting frame 1 and the plows 2. Simultaneously, the second motor 8 drives the lead screw. 9 rotates, and under the guidance of the limiting plate 11, the scraper 10 can move up and down in a directional manner through the rotation of the screw 9. After adjusting the digging depth of the plow head 2, the smoothing height of the scraper 10 can be adjusted. When it is necessary to adjust the width of the ridge, the operation of the first motor 3 drives the bidirectional threaded rod 4 to rotate. Under the guidance of the guide slider 6, the two threaded blocks 5 can drive the two plow heads 2 to move relative to or in opposite directions through the rotation of the bidirectional threaded rod 4. Thus, the ridge mechanism can adjust the distance between the two plow heads 2 according to the required ridge width. After ridge, the ridge surface can be covered with film through an additional film covering mechanism.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
