Description

Technical Field

[0001] This invention relates to the field of furrow building machines, specifically to an agricultural furrow building machine with adjustable depth. Background Technology

[0002] As an agricultural machine, the ridge-building machine can be used to build field ridges and irrigation ditches. When in use, it can be driven by a tractor to control its movement to form ridges. In different regions, the ridge-building machine may also be called a ridging machine or a furrow-building machine. It effectively shapes the ground in the field to form planting ridges, thereby increasing the yield after planting. However, there are still some problems with the use of existing ridge-building machines.

[0003] In the prior art, the patent announcement number CN107736096A describes a rotary tiller and a ridging machine, which includes a rotary tiller module and a ridging machine module connected to the front end of the rotary tiller module. The ridging machine module includes a leveling wheel axle, on which at least one pair of ridge leveling wheels are provided. Both ends of the leveling wheel axle are rotatably inserted into the ridging machine connecting part. The ridging machine connecting part is connected to the rotary tiller module. The rotary tiller module or the ridging machine module is provided with a drive device, which is connected to one end of the leveling wheel axle.

[0004] During the operation of the above-mentioned device, the existing rotary tiller module and ridging machine module are improved to make their structure more compact and stable, and their transmission more efficient. The two are effectively combined through the ridging machine connection part, realizing soil crushing and ridging in one step, which improves the work efficiency. However, when using it, it is not convenient to effectively control the height of the ridging machine according to the required ridging height, which can easily affect the range of use during operation.

[0005] In the prior art, the "Adjustable Ridging Machine" in patent announcement number CN108184347A includes a drive head, a ridge-forming mechanism, a compaction mechanism, and a furrow-forming mechanism arranged sequentially from front to back; the ridge-forming mechanism can form ridges, the compaction mechanism can compact and shape them, and the furrow-forming mechanism is used for final furrow shaping; both the ridge-forming mechanism and the compaction mechanism can be easily adjusted to the required ridge shape.

[0006] In the prior art, the patent announcement number CN116918494A, entitled "A Paddy Field Edge Ridging Machine", includes a ridger body, a support frame disposed on the ridger body, a rotating cylinder disposed on the support frame, and a depth limiting wheel disposed on the rotating cylinder; the adjustment component includes a guide assembly disposed on the rotating cylinder, an insertion assembly disposed on the guide assembly, a transmission assembly disposed on the rotating cylinder, a limiting assembly disposed on the transmission assembly, and a closing assembly disposed on the transmission assembly;

[0007] During the operation of the above-mentioned device, by setting anti-loosening components, it is possible to prevent the depth limiting wheel from becoming loose after adjustment, thus ensuring the stability of the depth limiting wheel after adjustment. This solves the problem that the fixed distance between the two depth limiting wheels can only meet the needs of a single ridge width, resulting in a limited range of applications. It achieves the effect of easy adjustment of the distance between the two depth limiting wheels and stable position of the limiting wheel after adjustment. However, in use, it is inconvenient to control the leveling height based on the ridge height, which can easily lead to inconvenience in coordinating ridge raising and leveling. Summary of the Invention

[0008] The purpose of this invention is to provide a depth-adjustable ridge-building machine for agricultural use, in order to solve the problems mentioned in the background art, such as the inconvenience of effectively controlling the height of the ridge-building machine according to the required ridge height, which easily affects the scope of use during operation, and the inconvenience of controlling the range of leveling height according to the ridge height, which easily leads to the problem of inconvenient coordination between ridge-building and leveling.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an agricultural ridge-building machine with adjustable depth, equipped with a frame that facilitates assembly onto agricultural machinery;

[0010] Includes: a bevel gear set, rotatably connected to the inner surface of the frame, and a nested ring is installed on the lower side of the horizontal gear in the bevel gear set, and the nested ring is built into the inner surface of the frame. At the same time, a threaded rod is threadedly connected to the inner surface of the bevel gear set and the nested ring, and a movable frame is installed on the lower surface of the threaded rod. The movable frame is equipped with a limit adjustment mechanism for positioning control.

[0011] The control component is installed on the front and rear sides of the outer surface of the frame. The inner surface of the control component is rotatably connected to the main gear, and the outer right side of the main gear is meshed with the auxiliary gear. At the same time, the outer sides of the main gear and the auxiliary gear are meshed with the rack, and the outer surface of the rack is equipped with a height rod, which is telescopically connected to the inner surface of the control component. The control component is also equipped with a limit locking mechanism for height adjustment.

[0012] A connecting rod is rotatably connected at one end to the right side of the outer surface of the frame, and a limiting shaft is nested at the other end of the inner surface of the connecting rod. A leveling frame is nested on the outer side of the limiting shaft, and a telescopic cylinder is rotatably connected to the upper surface of the leveling frame. The other end of the telescopic cylinder is rotated to the middle section of the outer surface of the frame. At the same time, a spacing plate is telescopically connected to the inner surface of the leveling frame, and a movable sleeve is nested on the inner surface of the spacing plate. A leveling wheel is nested on the outer surface of the movable sleeve, and a main shaft is slidably connected to the inner surface of the movable sleeve. The main shaft is positioned and rotated on the lower surface of the leveling frame.

[0013] Preferably, the frame forms a positioning and rotating structure through a nested ring and a bevel gear set, and the bevel gear set is evenly spaced about the inner surface side of the frame. The bevel gear set, the nested ring, and the threaded rod form a threaded structure, and the threaded rod and the moving frame form an integral structure.

[0014] With the above structure, it is easy to stably control the up and down movement of the threaded rod during use, control the height of the moving frame, and the limiting block assembled with the moving frame prevents the threaded rod from twisting and jamming.

[0015] Preferably, in the limiting adjustment mechanism, a limiting block is installed on the outer side of the movable frame and the limiting block is limited to slide on the inner surface of the movable frame. A lead screw is rotatably connected to the inner surface of the movable frame, and a movable block is threadedly connected to the outer surface of the lead screw and the movable block is limited to slide on the inner surface of the movable frame. Meanwhile, a spacing frame is installed on the lower surface of the movable block, and a positioning shaft is rotatably connected to the inner surface of the spacing frame. A gathering plate is installed on the lower surface of the positioning shaft.

[0016] An angle groove is provided on the right side of the inner surface of the spacing frame, and an angle shaft is slidably connected to the inner surface of the angle groove. A telescopic rod is rotatably assembled on the outer surface of the angle shaft, and a telescopic component is telescopically connected to the outer surface of the telescopic rod, and the telescopic component is positioned and rotated on the upper surface of the spacing frame.

[0017] The above structure facilitates stable assembly of the spacing frame during use, and allows for spacing adjustment based on usage conditions. Furthermore, the use of the gathering plate on the spacing frame allows for control of its angle and spacing during use.

[0018] Preferably, the limiting block and the middle section of the outer surface of the movable frame are symmetrically embedded and installed, and the movable frame forms a limiting sliding structure with the frame through the limiting block, and the movable frame forms a threaded adjustable limiting sliding structure with the spacing frame through the lead screw and the movable block, while the spacing frame forms a positioning rotation structure with the gathering plate through the positioning shaft.

[0019] The above structure facilitates stable control of the lifting and lowering stability of the mobile frame during use, thereby controlling the height adjustment of the gathering plate, the height adjustment of the ridging, and the height difference between the plate and the support wheels used on the side. It also controls the spacing adjustment of the gathering plate and improves the stability of the ridging width adjustment.

[0020] Preferably, the inner surface of the angle groove has an arc-shaped structure, and the spacing frame forms a limiting sliding structure with the angle axis through the angle groove, and the angle axis forms a telescopic adjustment positioning rotation structure with the spacing frame through the telescopic rod and telescopic component.

[0021] The above structure facilitates stable control of the position of the angle axis on the spacing frame during use, thereby controlling the angle adjustment of the gathering plate and controlling the amount of soil gathered.

[0022] Preferably, the control component is embedded in the front and rear sides of the outer surface of the frame, and the control component forms a limiting lifting structure with the height rod through the main gear, the secondary gear and the rack, and the rack and the height rod form an integral structure. At the same time, the height rod is symmetrically arranged about the inner surface of the control component.

[0023] The above structure allows for effective control of the height adjustment of the height bar during use, thereby controlling the height of the support wheels. When used in conjunction with the gathering plate, it controls the height adjustment range.

[0024] Preferably, in the limiting engagement mechanism, the inner surface of the height rod assembled with the control component has a slot, and a secondary rod is telescopically connected to the lower side of the inner surface of the height rod. A slider is installed on the upper end of the outer surface of the secondary rod, and a compression spring is nested between the secondary rod and the height rod. At the same time, a support wheel is rotatably connected to the outer surface of the secondary rod.

[0025] The inner surface of the slot can be connected to a limit rod, and one end of the outer surface of the limit rod is rotatably connected to a connecting rod, and the other end of the outer surface of the connecting rod is rotatably connected to an off-axis. The off-axis is installed on the outer side of the turntable, and the turntable is rotatably connected to the inner surface of the control component.

[0026] The above structure facilitates effective control of the stability of the support wheels during use, improves stability on uneven ground, and, in conjunction with the limit rod, controls the stability of the height rod during use.

[0027] Preferably, the slots are arranged at equal vertical distances from the right side of the outer surface of the height rod, and the height rod forms an elastically adjustable limiting sliding structure with the auxiliary rod through a compression spring and a slider, and the auxiliary rod forms a rotating structure with the support wheel.

[0028] With the above structure, the height adjustment bar, in conjunction with the elastically assembled auxiliary bar, effectively controls the stability of the support wheel, prevents it from being suspended in mid-air, and provides automatic height adjustment when used on uneven ground.

[0029] Preferably, the limiting rod forms a limiting engagement structure with the height rod through a slot, and the limiting rod forms a linkage rotation sliding structure with the turntable through a connecting rod and an offset shaft, and the turntable forms a positioning rotation structure with the control component.

[0030] The above structure effectively controls the position of the limit rod during use, thereby effectively limiting the height rod after adjustment and preventing slippage that could cause height deviation.

[0031] Preferably, the connecting rod and the machine frame form a positioning and rotating structure, and the other end of the connecting rod forms a positioning and nesting structure with the leveling frame through a limiting shaft. The leveling frame forms a telescopic and adjustable rotating structure with the machine frame through a telescopic cylinder. At the same time, the leveling frame forms a sliding nesting structure with the moving sleeve through a spacing plate. The moving sleeve and the leveling wheel have an external locking and nesting structure. The moving sleeve and the main shaft form an internal limiting and sliding structure. Meanwhile, the main shaft and the leveling frame form a rotating structure.

[0032] With the above structure, the stability of the connecting rod, frame, and leveling frame can be effectively controlled during use. In conjunction with the use of the spacing plate and the movable sleeve, the spacing of the leveling wheels can be stably controlled, and the position of the spacing plate can be controlled independently, thereby controlling the position of the leveling wheels.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] 1. A limit adjustment mechanism is set up. The bevel gear set effectively matches the nested ring to control the position of the threaded rod, thereby adjusting the height of the moving frame. When the moving frame is adjusted, the use of limit blocks prevents the threaded rod from tilting and jamming. The screw on the moving frame controls the width between the moving blocks and the installation spacing of the frames, thereby controlling the width between the gathering plates. It also works in conjunction with the angle adjustment of the gathering plates to control the amount of soil gathered and cooperate with the leveling wheels in the later stage.

[0035] 2. A limit locking mechanism is provided to facilitate the rotation of the motor on the control assembly, adjust the meshing rotation between the main gear and the auxiliary gear, thereby controlling the position of the height rod installed on the rack, and then adjusting the height rod to form a limit adjustment on the inner surface of the control assembly. In conjunction with the rotary control turntable, it effectively controls the limit rod of the connecting rod assembly to form a limit locking action on the height rod.

[0036] Furthermore, the height bar, when in use, effectively controls the elastic buffer of the support wheel through the elastically assembled sub-bar, forming contact to prevent suspension when the ground is uneven;

[0037] 3. It is equipped with a connecting rod that is easy to rotate. One end rotates to assemble the frame, and the other end is used to assemble with the leveling frame in conjunction with the limiting shaft. This allows the leveling frame to be used at an angle controlled by a telescopic hydraulic cylinder, thereby controlling the height of the leveling wheels assembled on the leveling frame and thus controlling the height of the raised beds.

[0038] Furthermore, the movable sleeve installed inside the leveling wheel is in a limiting sliding fit with the main shaft, which can control the main shaft, leveling wheel and movable sleeve to rotate simultaneously while rotating. The movable sleeve, in conjunction with the nested spacing plate, controls the position of the leveling wheel. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Please see Figures 1-10 The present invention provides a technical solution: an agricultural ridge-building machine with adjustable depth, which is equipped with a frame 1 for easy assembly on agricultural machinery;

[0052] Example 1: As Figures 1-5 The present invention provides the following technical solution: a depth-adjustable agricultural ridge-building machine, which discloses:

[0053] Includes: a bevel gear set 2, rotatably connected to the inner surface of the frame 1, and a nested ring 3 is installed on the lower side of the horizontal gear in the bevel gear set 2, and the nested ring 3 is built into the inner surface of the frame 1. At the same time, the inner surfaces of the bevel gear set 2 and the nested ring 3 are threadedly connected to a threaded rod 4, and a movable frame 5 is installed on the lower surface of the threaded rod 4. The movable frame 5 is equipped with a limit adjustment mechanism for positioning control.

[0054] The frame 1 forms a positioning and rotating structure with the nested ring 3 and the bevel gear set 2. The bevel gear set 2 is set at equal distances from the inner surface side of the frame 1. The bevel gear set 2, the nested ring 3, and the threaded rod 4 form a threaded structure. At the same time, the threaded rod 4 and the moving frame 5 form an integrated structure.

[0055] In the limit adjustment mechanism, a limit block 6 is installed on the outer side of the movable frame 5 and the limit block 6 is limited to slide on the inner surface of the movable frame 5. A lead screw 7 is rotatably connected to the inner surface of the movable frame 5, and a movable block 8 is threadedly connected to the outer surface of the lead screw 7 and the movable block 8 is limited to slide on the inner surface of the movable frame 5. Meanwhile, a spacing frame 9 is installed on the lower surface of the movable block 8, and a positioning shaft 10 is rotatably connected to the inner surface of the spacing frame 9. At the same time, a gathering plate 11 is installed on the lower surface of the positioning shaft 10.

[0056] An angle groove 901 is provided on the right side of the inner surface of the spacing frame 9, and an angle shaft 902 is slidably connected to the inner surface of the angle groove 901. A telescopic rod 903 is rotatably assembled on the outer surface of the angle shaft 902. At the same time, a telescopic component 904 is telescopically connected to the outer surface of the telescopic rod 903, and the telescopic component 904 is positioned and rotated on the upper surface of the spacing frame 9.

[0057] The limiting block 6 and the moving frame 5 are symmetrically embedded in the middle section of the outer surface. The moving frame 5 forms a limiting sliding structure with the frame 1 through the limiting block 6. The moving frame 5 forms a threaded adjustable limiting sliding structure with the spacing frame 9 through the lead screw 7 and the moving block 8. At the same time, the spacing frame 9 forms a positioning rotation structure with the gathering plate 11 through the positioning shaft 10.

[0058] The inner surface of the angle groove 901 has an arc-shaped structure, and the spacing frame 9 forms a limiting sliding structure with the angle shaft 902 through the angle groove 901. The angle shaft 902 forms a positioning and rotating structure with the spacing frame 9 through the telescopic rod 903 and the telescopic component 904 to form a telescopic adjustment.

[0059] In use, the frame 1 is assembled onto the agricultural machinery, thereby controlling the components on the frame 1. When it is necessary to control the ridging height using the frame 1, the motor on the frame 1 is rotated, which, in conjunction with the belt and shaft, controls the rotation of the bevel gear set 2. This rotation drives the horizontal gear on the bevel gear set 2 to engage with the nested ring 3 and the frame 1, effectively forming a threaded adjustment with the threaded rod 4. When adjusting the height of the threaded rod 4, the limiting block 6, which is mounted on the lower part of the movable frame 5, slides on the lower end of the inner surface of the frame 1, improving the stability of the movable frame 5. It can also be used in conjunction with the motor built into the movable frame 5 to control the threaded control between the lead screw 7 and the movable block 8, and adjust the movement. Block 8 slides on the inner surface of the movable frame 5 to control the width between the spacing frames 9 installed on the movable block 8, and to control the ridging width. The spacing frames 9 are connected by the telescopic assembly 904. When the telescopic assembly 904 is telescopically adjusted, the telescopic rod 903 of the telescopic assembly 904 is telescopically adjusted, and the angle shaft 902 is driven to slide in the angle groove 901 to limit the movement. The gathering plate 11 assembled on the lower side of the angle shaft 902 is also driven to rotate with the positioning shaft 10 installed on it to form a positioning rotation with the spacing frame 9. This can also control the height and width of the ridging. This can be combined with the height adjustment of the movable frame 5, the spacing adjustment of the spacing frames 9, and the angle adjustment of the gathering plate 11 to control the height and width of the ridging.

[0060] Example 2: Figure 1 , Figure 2 , Figure 6 , Figure 7 and Figure 8 The technical solution shown, based on Embodiment 1, further discloses a control component 12 for adjusting the height of the support wheel 21, the specific details of which are as follows:

[0061] The control component 12 is installed on the front and rear sides of the outer surface of the frame 1. The inner surface of the control component 12 is rotatably connected to the main gear 13, and the right side of the outer surface of the main gear 13 is meshed with the auxiliary gear 14. At the same time, the outer sides of the main gear 13 and the auxiliary gear 14 are meshed with the rack 15, and the outer surface of the rack 15 is equipped with a height rod 16, which is telescopically connected to the inner surface of the control component 12. The control component 12 is also provided with a limit locking mechanism for height adjustment.

[0062] The control component 12 is embedded in the front and rear sides of the outer surface of the frame 1. The control component 12 forms a limit lifting structure with the height rod 16 through the main gear 13, the auxiliary gear 14 and the rack 15. The rack 15 and the height rod 16 form an integrated structure. The height rod 16 is symmetrically arranged about the inner surface of the control component 12.

[0063] In the limiting engagement mechanism, the inner surface of the height rod 16 assembled by the control component 12 is provided with a slot 17, and the lower side of the inner surface of the height rod 16 is telescopically connected to a secondary rod 18. A slider 19 is installed on the upper end of the outer surface of the secondary rod 18, and a compression spring 20 is nested between the secondary rod 18 and the height rod 16. At the same time, a support wheel 21 is rotatably connected to the outer surface of the secondary rod 18.

[0064] The inner surface of the slot 17 can be connected to the limit rod 1701, and one end of the outer surface of the limit rod 1701 is rotatably connected to the connecting rod 1702, and the other end of the outer surface of the connecting rod 1702 is rotatably connected to the off-axis 1703. The off-axis 1703 is installed on the outer side of the turntable 1704, and the turntable 1704 is rotatably connected to the inner surface of the control component 12.

[0065] The slot 17 is set at equal distances above and below the right side of the outer surface of the height rod 16, and the height rod 16 forms an elastically adjustable limiting sliding structure with the auxiliary rod 18 through the compression spring 20 and the slider 19, and the auxiliary rod 18 forms a rotating structure with the support wheel 21.

[0066] The limiting rod 1701 forms a limiting engagement structure with the height rod 16 through the slot 17, and the limiting rod 1701 forms a linkage rotation sliding structure with the turntable 1704 through the connecting rod 1702 and the off-axis 1703, and the turntable 1704 forms a positioning rotation structure with the control component 12.

[0067] When adjusting the height of the gathering plate 11, the motor built into the control assembly 12 can be used to rotate and adjust the main gear 13 and the secondary gear 14 to control the height lever 16 mounted on the rack 15 to rise and fall on the inner surface of the control assembly 12, thereby controlling the rise and fall of the frame 1. After the height lever 16 is adjusted, the motor assembled on the outer surface of the control assembly 12 can be controlled to rotate the turntable 1704, which in turn drives the off-axis 1703 assembled on the turntable 1704 to control the connecting rod 1702 set at the same angle to rotate in a linkage manner, and drives the limiting rod assembled on the connecting rod 1702 to rotate in a linkage manner. The positioning rod 1701 forms a limiting slide inside the control component 12, thereby controlling the positioning rod 1701 to engage with the slot 17 provided on the height rod 16 for positioning, controlling the stability of the height rod 16, and when the support wheel 21 assembled on the height rod 16 is used on uneven road surfaces, the auxiliary rod 18 assembled on the support wheel 21, together with the installed slider 19, forms a limiting slide on the inner surface of the height rod 16, and the compression spring 20 assembled between the auxiliary rod 18 and the height rod 16 forms an elastic buffer to prevent the support wheel 21 assembled on the auxiliary rod 18 from being suspended;

[0068] Example 3: Figure 1 , Figure 2 , Figure 9 and Figure 10 The technical solution shown, based on Embodiment 2, further discloses that the connecting rod 22 controls the rotational stability of the leveling frame 24 and controls the height and spacing of the leveling wheels 28, the specific details of which are as follows:

[0069] One end of the connecting rod 22 is rotatably connected to the right side of the outer surface of the frame 1, and the other end of the inner surface of the connecting rod 22 is nested with a limiting shaft 23. The outer side of the limiting shaft 23 is nested with a leveling frame 24, and the upper surface of the leveling frame 24 is rotatably connected with a telescopic cylinder 25. The other end of the telescopic cylinder 25 is rotated to the middle section of the outer surface of the frame 1. At the same time, the inner surface of the leveling frame 24 is telescopically connected with a spacing plate 26, and the inner surface of the spacing plate 26 is nested with a movable sleeve 27. The outer surface of the movable sleeve 27 is nested with a leveling wheel 28, and the inner surface of the movable sleeve 27 is slidably connected with a main shaft 29, which is positioned and rotated on the lower surface of the leveling frame 24.

[0070] The connecting rod 22 and the frame 1 form a positioning and rotating structure, and the other end of the connecting rod 22 forms a positioning and nesting structure with the leveling frame 24 through the limiting shaft 23. The leveling frame 24 forms a telescopic and adjustable rotating structure with the frame 1 through the telescopic cylinder 25. At the same time, the leveling frame 24 forms a sliding nesting structure with the moving sleeve 27 through the spacing plate 26. The moving sleeve 27 and the leveling wheel 28 have an external locking and nesting structure. The moving sleeve 27 and the main shaft 29 form an internal limiting and sliding structure. At the same time, the main shaft 29 and the leveling frame 24 form a rotating structure.

[0071] When the height of the gathering plate 11 is adjusted in conjunction with the height of the support wheel 21, the stability of the ridge-building machine's height adjustment is effectively controlled, as well as the height and width of the ridges. After centering in the soft soil, the telescopic cylinder 25 can be controlled to extend and retract, driving the leveling frame 24 to rotate in conjunction with the limiting shaft 23 and connecting rod 22 of the limiting assembly. This positions the leveling wheel 28 on the right side of the outer surface of the frame 1, thereby controlling the height of the leveling wheel 28 assembled on the leveling frame 24. In conjunction with the cylinder assembled on the leveling frame 24, the adjustment of the spacing plate 26 is effectively controlled, thereby controlling the moving sleeve 27 nested in the spacing plate 26 to adjust the leveling wheel 28 to form a limiting slide on the outer surface of the main shaft 29. When the moving sleeve 27 is adjusted, it can be coordinated with the rotation of the main shaft 29 to synchronously control the moving sleeve 27 and the leveling wheel 28 to form a positioning rotation under the nesting of the spacing plate 26, improving the stability of use and controlling the stability of the ridge-leveling width.
