Description
Technical Field
[0001] This utility model belongs to the field of plowing technology, specifically relating to a manual adjustment mechanism for horizontal and vertical directions. Background Technology
[0002] A furrowing plow is a moldboard-type furrowing implement. Types include deep furrow plows, green manure furrow plows, and symmetrical furrow plows. The furrowing structure of a plow mainly consists of the moldboard, plowshare, plowpost, and plow rest. The moldboard is the primary component, and its shape and material directly affect the furrowing effect and quality. The plowshare guides the soil upwards and turns it to both sides of the furrow, helping to form neat furrows. The plowpost and plow rest provide support and connection, ensuring the stability and reliability of the entire furrowing structure. For non-permanent farmland irrigation and drainage ditches with a furrow depth of 30 cm or less, a furrow plow consists of a frame, suspension frame, and plow body. The plow body has a symmetrical working surface, and the plowshare wings are equipped with flat soil plates. During furrowing, the plow body turns the soil to both sides, and the flat soil plates are used to push and level the soil turned onto the ground.
[0003] In existing technologies, the furrow opener in a plow is fixedly mounted on the plow. However, soil conditions in farmland are often complex and varied, including soil moisture, hardness, and type. If the furrow opener cannot adjust the furrow depth according to actual needs, it will be difficult to adapt to the tillage requirements under different soil conditions, which may lead to poor tillage results, reduce tillage efficiency, affect crop production and yield, and thus reduce the practicality of the plow.
[0004] Therefore, a manual adjustment mechanism for both horizontal and vertical directions is needed to solve the problem that existing trenchers cannot adjust the trenching depth according to actual needs. Utility Model Content
[0005] The purpose of this invention is to provide a manual adjustment mechanism for both horizontal and vertical directions to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a manual adjustment mechanism for both horizontal and vertical directions, comprising a frame, a lead screw frame fixedly connected to the right side of the frame, a first rocker arm rotatably connected above the lead screw frame, a lead screw rotatably connected inside the lead screw frame, and the bottom end of the first rocker arm fixedly connected to the lead screw, a slider threadedly connected to the outside of the lead screw, a first connecting plate fixedly connected to the right side of the slider, a first channel steel fixedly connected to the right side of the first connecting plate, a roller rollingly connected inside, and a trencher fixedly connected to the right side of the roller.
[0007] It should be noted in the solution that the internal structure of the lead screw frame is symmetrically fixed with sliding rods, and the sliding rods are symmetrically arranged on the front and rear sides of the lead screw. The slider has holes that are adapted to the sliding rods.
[0008] It is worth noting that a movable block is fixedly connected to the right side of the trencher, and a second channel steel is provided on the right side of the trencher, which is slidably connected to the inside of the second channel steel by the movable block.
[0009] Furthermore, it should be noted that a second connecting plate is fixedly connected to the back of the second channel steel, and an inclined fixing plate is fixedly connected to the top of the second connecting plate.
[0010] In a preferred embodiment, a telescopic frame is connected to the right side of the vertical plate of the second connecting plate, and a connecting column is rotatably connected to the staggered position of the telescopic frame, which is rotatably connected to the vertical plate of the second connecting plate through the connecting column.
[0011] In a preferred embodiment, a second rocker arm is fixedly connected to the upper back of the frame, and a transmission structure is fixedly connected to the lower part of the second rocker arm. A drive pulley is fixedly connected to the output end of the transmission structure, and a belt is externally engaged with the drive pulley. A driven pulley is internally engaged with the front end of the belt.
[0012] In a preferred embodiment, a third connecting plate is fixedly connected above the second connecting plate on the front side, the driven pulley passes through the interior of the third connecting plate, and the interior of the third connecting plate is provided with a toothed block that meshes with the driven pulley.
[0013] In a preferred embodiment, a slide rail is fixedly connected to the lower rear side of the frame, and the second connecting plate is slidably connected above the slide rail.
[0014] Compared with the prior art, the lateral and longitudinal manual adjustment mechanism provided by this utility model has at least the following beneficial effects:
[0015] (1) By setting the first rocker, lead screw, slide bar, slider, first connecting plate and first channel steel, the furrow opener is driven to rise and fall. At the same time, it completes self-locking when a suitable height is determined, so as to meet the needs of different sowing depths and improve the applicability and practicality of the mechanism.
[0016] (2) By setting the second connecting plate, telescopic frame, second rocker, active pulley, belt and third connecting plate, the trencher can be adjusted synchronously to quickly adapt to different operation requirements without stopping the machine to adjust or replace parts, thereby improving operation efficiency and further expanding the applicability of the mechanism.

[0022] The present invention will be further described below with reference to the embodiments.
[0023] Please see Figure 1-4 This utility model provides a horizontal and vertical manual adjustment mechanism, including a frame 1, a lead screw frame 2 fixedly connected to the right side of the frame 1, a first rocker arm 3 rotatably connected to the top of the lead screw frame 2, a lead screw 4 rotatably connected inside the lead screw frame 2, and the bottom end of the first rocker arm 3 fixedly connected to the lead screw 4, a slider 6 threadedly connected to the outside of the lead screw 4, a first connecting plate 7 fixedly connected to the right side of the slider 6, a first channel steel 8 fixedly connected to the right side of the first connecting plate 7, a roller 9 rollingly connected inside, and a trencher 10 fixedly connected to the right side of the roller 9.
[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the internal structure of the lead screw frame 2 is symmetrically fixed with slide rods 5, and the slide rods 5 are symmetrically arranged on the front and rear sides of the lead screw 4. The slider 6 has holes that are compatible with the slide rods 5.
[0025] Since the slider 6 is slidably connected to the outside of the slider 5, the rotation of the slider 6 can be restricted, preventing the slider 6 from rotating with the lead screw 4 and ensuring that the slider 6 moves up and down stably.
[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that a movable block is fixedly connected to the right side of the trencher 10, and a second channel steel 11 is provided on the right side of the trencher 10, which is slidably connected to the inside of the second channel steel 11 by the movable block.
[0027] As can be seen from the above working process, the first rocker arm 3, lead screw 4, slide bar 5, slider 6, first connecting plate 7 and first channel steel 8 are set to drive the furrow opener 10 to rise and fall. At the same time, it completes self-locking when a suitable height is determined, so as to meet the requirements of different sowing depths and improve the applicability and practicality of the mechanism.
[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a second connecting plate 12 is fixedly connected to the back of the second channel steel 11, and an inclined fixing plate 20 is fixedly connected to the top of the second connecting plate 12.
[0029] By using the inclined fixing plate 20, a stable triangular support is formed between the second connecting plate 12 and the inclined fixing plate 20, thereby improving the stability and load-bearing capacity of the overall structure.
[0030] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a telescopic frame 13 is connected to the right side of the vertical plate of the second connecting plate 12. A connecting column is rotatably connected to the staggered position of the telescopic frame 13, and the connecting column is rotatably connected to the vertical plate of the second connecting plate 12.
[0031] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a second rocker arm 14 is fixedly connected to the upper back of the frame 1, and a transmission structure is fixedly connected to the lower part of the second rocker arm 14. A drive pulley 15 is fixedly connected to the output end of the transmission structure. A belt 16 is meshed with the outside of the drive pulley 15. A driven pulley 18 is meshed with the front end of the belt 16. A third connecting plate 17 is fixedly connected to the upper part of the second connecting plate 12 on the front side. The driven pulley 18 passes through the interior of the third connecting plate 17, and a toothed block that meshes with the driven pulley 18 is provided inside the third connecting plate 17.
[0032] While the belt 16 rotates, the engagement between the belt 16 and the third connecting plate 17 drives the second connecting plate 12 on the front to move. Then, the connecting column on the second connecting plate 12 drives the telescopic frame 13 to extend and retract, which can drive the other second connecting plates 12 to move simultaneously, thereby synchronously adjusting the row spacing of the trencher 10.
[0033] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that a slide rail 19 is fixedly connected to the lower rear side of the frame 1, and the second connecting plate 12 is slidably connected to the upper part of the slide rail 19.
[0034] The sliding rail 19 further ensures the stability of the second connecting plate 12 during movement, thereby ensuring the stability of the trencher 10 when adjusting the spacing.
[0035] This solution has the following working process: In use, firstly, rotating the first rocker arm 3 drives the lead screw 4 to rotate. Since the slider 6 is slidably connected to the outside of the slide rod 5, the rotation of the slider 6 can be restricted, preventing it from rotating with the lead screw 4 and ensuring stable up-and-down movement. This, in turn, drives the first channel steel 8 to move via the first connecting plate 7, and the furrow opener 10 to move via the roller 9. The sliding block on the right side of the furrow opener 10 slides inside the second channel steel 11, improving the stability of the furrow opener 10's movement and thus enabling the furrow opener 10 to be raised and lowered to meet the needs of different sowing depths. Then, rotating the second rocker arm 14... The drive pulley 15 rotates, which in turn drives the driven pulley 18 to rotate via the belt 16. This causes the belt 16 to rotate, and as it rotates, it engages with the third connecting plate 17, which in turn moves the second connecting plate 12. The connecting column on the second connecting plate 12 then drives the telescopic frame 13 to extend and retract, which in turn moves the other second connecting plates 12 simultaneously. This allows for synchronous adjustment of the row spacing of the trencher 10, enabling it to quickly adapt to different operational needs without requiring machine downtime for adjustments or parts replacement. This improves operational efficiency and expands the applicability of the mechanism.
[0036] In summary: By using the first rocker arm 3, lead screw 4, slide bar 5, slider 6, first connecting plate 7, and first channel steel 8, the furrow opener 10 is driven to rise and fall, and self-locking is completed when a suitable height is determined, thus meeting the requirements of different sowing depths and improving the applicability and practicality of the mechanism. By using the second connecting plate 12, telescopic frame 13, second rocker arm 14, drive pulley 15, belt 16, and third connecting plate 17, the row spacing of the furrow opener 10 can be adjusted synchronously, quickly adapting to different operational needs without stopping the machine for adjustment or replacement of parts, thereby improving operational efficiency and further expanding the applicability of the mechanism.
