Description

Technical Field

[0001] The present invention relates to the technical field of ridging machines, and particularly relates to a distance-adjusting and resistance-reducing wheat ridging and forming machine. Background Art

[0002] In agricultural production, in order to sow or raise seedlings, ridging needs to be carried out on cultivated land. The traditional ridging method is that operators use tools such as shovels for manual ridging. The ridges are prone to tilting and uneven height, resulting in uneven seedling raising. With the development of agricultural production mechanization, ridging machines have emerged to carry out mechanical ridging on cultivated land. Ridging machines are mainly applicable to post-tillage ridging operations in the fields of potatoes, beans, and vegetables. Most ridging machines are self-propelled or traction type, and there is a large traction resistance during the working process.

[0003] In order to maintain a certain depth and operation safety during the operation of agricultural implements under the condition of changing soil resistance, the prior art usually uses a pointed ridging plow to achieve ditch opening and ridging, so that the soil enters both sides along the pointed ridging plow to form ridges. The pointed ridging plow consists of two inclined and symmetrical ridging plates. In order to adjust the ridge distance as needed, adjusting the inclination of the ridging plates can achieve the adjustment of the ridge distance.

[0004] However, in the process of increasing the ridge distance, it is necessary to increase the included angle between the ridging plates, so that the ends of the ridging plates gradually move outwards. In the actual application process, the larger the angle between the ridging plate and the soil in the ridging direction, the greater the resistance received by the ridging plate during the ridging process. Therefore, the ridging resistance can also increase during the process of adjusting the ridge distance. Summary of the Invention

[0005] For this reason, the present invention provides a distance-adjusting and resistance-reducing wheat ridging and forming machine, which effectively solves the problem that the ridging resistance may increase significantly during the process of adjusting the ridge distance in the prior art.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0046] As Figure 1 and Figure 2 shown, the present invention provides a distance - adjustable and drag - reducing wheat ridging and forming machine, which includes a frame 1, a ridging plate group 2, and a distance adjustment structure 3.

[0047] The frame 1 is provided with a ridge pressing roller group 4 on both sides thereof. An installation shaft column 15 is arranged on the ridge pressing roller group 4. The ridge pressing roller group 4 is installed on the frame 1 through the installation shaft column 15. A ridge pressing cavity wall 5 is formed inside the ridge pressing roller group 4. The ridge pressing cavity wall 5 translates to press the soil pushed into the ridge pressing cavity wall 5 into a formed ridge heap 6. A ridge furrow 7 is formed between the formed ridge heaps 6.

[0048] The ridging plate group 2 is set in two groups and symmetrically installed on the frame 1. The ridging plate group 2 is provided with a number of ridging blades 21. The ridging ends of the ridging blades 21 are arranged in the width direction of the furrow 7. A soil-pushing channel 22 is formed between the ridging blades 21. Both the ridging blades 21 and the soil-pushing channel 22 are arc-shaped, and each ridging blade 21 corresponds to the same central axis. A soil guiding plate 23 is arranged at the end of the soil-pushing channel 22. The soil guiding plate 23 faces the ridging cavity wall 5. A boosting impeller 24 is rotatably installed inside the ridging blade 21.

[0049] The distance-adjusting structure 3 is installed at the upper end of the ridging blade 21. A distance-adjusting base rod 31 is arranged on the distance-adjusting structure 3. The distance-adjusting base rod 31 passes through the extension line of the central axis of the ridging blade 21. A translation cylinder base 32 is arranged on the distance-adjusting base rod 31 in a translational manner. The upper end of the ridging blade 21 is installed on the translation cylinder base 32.

[0050] Among them, the distance-adjusting structure 3 is used to drive the translation cylinder base 32 to translate on the distance-adjusting base rod 31, so as to drive the outermost ridging blade 21 to move along the radial direction of the circle where it is located, so that the end of the ridging blade 21 moves along the width direction of the furrow 7 to adjust the ridge distance.

[0051] The above mainly ridges the soil through the ridging blade 21. The ridging blade 21 pushes the ridged soil to both sides, and the soil is pressed by the ridging cavity wall 5 to form a formed ridge pile 6. The position of the end of the ridging blade 21 determines the size of the furrow 7 and the ridge distance.

[0052] In the present invention, the cultivated land is ridged by the ridging blade 21. The ridging blade 21 is arc-shaped. During the ridging process, the soil can enter the ridge pile through the soil-pushing channel 22. The arc-shaped design ensures a certain reduction in the ridging resistance. In addition, in the present invention, the distance-adjusting structure 3 drives the translation cylinder base to translate on the distance-adjusting base rod 31, so as to drive the ridging blade 21 to move along the radial direction of the circle where it is located, so that the end of the ridging blade 21 moves along the width direction of the furrow 7 to adjust the ridge distance. During the adjustment of the ridge distance, the overall width in the soil-pushing channel 22 changes, but the radian does not change, maintaining the stability of the ridging resistance while realizing the adjustment of the ridge distance.

[0053] In addition, in the present invention, a boosting impeller 24 is rotatably installed inside the ridging blade 21. Under the boosting action of the boosting impeller 24, a thrust is given to the soil to enter the ridge pile from the soil-pushing channel 22, further reducing the resistance during the ridging process.

[0054] Considering that the ridging blade 21 can be placed in the soil, the thickness of the ridging blade 21 needs to be set thinner. If only one blade is set, the soil in the other soil-pushing channel 22 may be subjected to an outward thrust on the inner side of the boosting impeller 24, resulting in an increase in resistance. Therefore, the present invention makes the following design, as Figure 1 and Figure 3As shown, the ridging blade 21 is composed of an inner pushing blade 211 and a supporting blade 212.

[0055] The boosting impeller 24 is installed on the inner pushing blade 211. A connecting gap 213 is provided between the inner pushing blade 211 and the supporting blade 212. An arc plate 214 is provided on the side wall of the inner pushing blade 211 close to the connecting gap 213, and the outer end of the boosting impeller 24 fits with the arc plate 214.

[0056] The boosting impeller 24 rotates clockwise outside the installation gap 213, which plays a role in pushing the soil entering the earth-pushing channel 22 forward. The part of the boosting impeller 24 inside the installation gap 213 will not push the soil in another earth-pushing channel 22 but only rotate on the inner wall of the arc plate 214.

[0057] Among them, during the boosting process, the boosting impeller 24 may also bring the soil into the installation gap 213. In order to prevent the soil from accumulating in the installation gap 213, the design of the arc plate 214 enables the soil entering the installation gap 213 to be taken out of the arc plate in time under the rotation of the boosting impeller 24, avoiding the accumulation of soil.

[0058] In the present invention, in order to prevent the resistance of the soil in the earth-pushing channel 22 from increasing sharply, the following design is also made in the present invention. The distance between adjacent ridging blades 21 is equal everywhere. The ends of the inner pushing blade 211 and the supporting blade 212 are jointly connected with a guiding plate 25. The guiding plate 25 is arranged along the length direction of the formed ridge heap 6. The soil guiding plate 23 is installed at the end of the guiding plate 25 through bolts, and the inclination of the soil guiding plate 23 can be adjusted.

[0059] In the above-mentioned embodiment, during the process of the soil from the entrance to the exit of the earth-pushing channel 22, the channel gradually tends to be closer to the same width direction as the ridge ditch 7. Therefore, during the gradual inner pushing of the soil, the resistance received by the soil gradually increases. The design of the guiding plate 25 enables the soil to gradually move forward a certain distance along the length direction of the ridge ditch 7 after coming out of the earth-pushing channel 22, and then enters the ridge pressing roller group 4 through the soil guiding plate 23, facilitating the pressing and forming of the soil.

[0060] Among them, the inclination of the soil guiding plate 23 can be adjusted, which can be achieved by adjusting the installation angle. The main purpose is that the end of the soil guiding plate 23 is just opposite to the end of the ridge pressing cavity wall 5, avoiding the soil from overflowing the ridge pressing cavity wall 5. When the ridge distance is adjusted, the outer end position of the ridge pressing cavity wall 5 changes. Correspondingly, the angle of the soil guiding plate 23 also changes, so that the end is always opposite to the end of the ridge pressing cavity wall 5.

[0061] In order to reduce the resistance suffered by the ridging blade 21 during the ridging process, the following design is also made in the present invention. A soil dividing tip plate 26 is provided at the end of the ridging blade 21 along the ridging direction, and the width of the soil dividing tip plate 26 gradually increases near one end of the ridging blade 21.

[0062] That is to say, the front end of the soil-dividing pointed plate 26 is pointed. The pointed design increases the pressure exerted on the soil by the ridging plow blade group 2, facilitating the smooth progress of the overall ridging and also enabling the soil to enter the soil-pushing channel 22 more smoothly.

[0063] In order to enable the distance-adjusting structure 3 to drive the inner pushing share 211 and the supporting share 212 to adjust their positions, the present invention also makes the following design, as Figure 5 shown, mounting arc plates 27 are installed on both side walls at the upper ends of the inner pushing share 211 and the supporting share 212. The mounting arc plates 27 are installed on the ridging share 21 through bolts 28. A connecting shaft frame 29 is connected to the upper end of the mounting arc plate 27, and the mounting arc plate 27 is installed on the translation cylinder base 32 through the connecting shaft frame 29.

[0064] When the translation cylinder base 32 translates, it drives the mounting arc plate 27 to translate along the direction of the distance-adjusting base rod 31 through the connecting shaft frame 29, thereby driving the inner pushing share 211 and the supporting share 212 to move.

[0065] In order to drive the position of the translation cylinder base 32 to be adjusted, the distance-adjusting structure 3 of the present invention adopts the following preferred embodiments, as Figure 3 and Figure 6 shown, the distance-adjusting structure 3 includes threaded sections 33 provided on the distance-adjusting base rod 31. The threaded sections 33 are provided in several numbers. Threads are provided on the threaded sections 33, and the thread pitch on the threaded sections 33 gradually approaching the extension line of the central axis of the ridging share 21 increases. The translation cylinder base 32 far from the extension line of the central axis of the ridging share 21 is rotatably arranged on the distance-adjusting base rod 31, and the remaining translation cylinder bases 32 are threadedly connected to the threaded sections 33. Each threaded section 33 corresponds to a translation cylinder base 32. A first driving motor 34 is provided on the distance-adjusting base rod 31, and the distance-adjusting base rod 31 is connected to the output end of the first driving motor 34.

[0066] In the above embodiment, the translation cylinder base 32 close to the first driving motor 34 is rotatably arranged on the distance-adjusting base rod 31. When the distance-adjusting base rod 31 rotates, the position of this translation cylinder base 32 on the distance-adjusting base rod 31 does not change.

[0067] The first driving motor 34 drives the distance-adjusting base rod 31 to rotate. Under the rotation of the distance-adjusting base rod 31, the translation cylinder seat 32 on the threaded section 33 can be driven to translate. The first translation cylinder seat 32 close to the first driving motor 34 is fixed. The second translation cylinder seat 32 and the third translation cylinder seat 32 translate on the distance-adjusting base rod 31. The larger the pitch, the farther the translation cylinder seat 32 translates on the distance-adjusting base rod 31. That is to say, the translation distance of the second translation cylinder seat 32 is greater than that of the third translation cylinder seat 32. Such a design can also make the distance between the second translation cylinder seat 32 and the third translation cylinder seat 32 gradually increase. During the translation process, the position of the first translation cylinder seat 32 remains unchanged, and both the second translation cylinder seat 32 and the third translation cylinder seat 32 translate. At this time, the distance between the first translation cylinder seat 32 and the second translation cylinder seat 32 increases, and the width of the earth-pushing channel 22 between them becomes larger. The distance between the second translation cylinder seat 32 and the third translation cylinder seat 32 also becomes larger, and the width of the earth-pushing channel 22 becomes larger. The width change of each earth-pushing channel 22 is roughly the same, and there is not much difference in width. In this case, the width difference of the earth-pushing channels 22 is small, the resistance difference of the soil entering the earth-pushing channels 22 is small, and the soil resistance in different earth-pushing channels 22 is evenly distributed, which can further increase the stability during the ridging process.

[0068] While realizing the translation of the translation cylinder seat 32, it is also necessary to limit the translation cylinder seat 32. Therefore, the present invention also makes the following design, as Figure 6 and Figure 7 shown, an inclined frame 8 is arranged on the frame 1. The inclined frame 8 is arranged directly above the distance-adjusting base rod 31 and is parallel to the distance-adjusting base rod 31. A vertical frame 9 is arranged at the bottom of the inclined frame 8. The first driving motor 34 is installed on the vertical frame 9. The bottom of the inclined frame 8 is connected with a limiting strip 35 through a connecting bolt 10. A limiting groove 36 is arranged on the outer wall of the translation cylinder seat 32. The limiting strip 35 is slidably arranged in the limiting groove 36.

[0069] The limiting strip 35 limits the translation cylinder seat 32, so that the translation cylinder seat 32 can only translate under the rotation of the distance-adjusting base rod 31 and cannot follow the rotation.

[0070] In order to drive the boosting impeller 24 to rotate, as Figure 4 shown, the present invention also makes the following design. The connecting shaft frame 29 is arc-shaped. A connecting cavity is arranged in the connecting shaft frame 29 corresponding to the upper part of the inner earth-pushing blade 211. A slot 215 is arranged on the side wall of the inner earth-pushing blade 211. The boosting impeller 24 extends outside the slot 215. A driving shaft 210 is connected to the boosting impeller 24. The driving shaft 210 penetrates through the inner earth-pushing blade 211, and the end of the driving shaft 210 extends into the connecting cavity. The end of the driving shaft 210 is rotatably arranged in the connecting cavity.

[0071] As Figure 8As shown, a rotating sprocket 11 is coaxially arranged at the end of the drive shaft 210. A drive chain 12 is arranged on the rotating sprocket 11. The drive chain 12 is arranged in the connecting cavity. A second drive motor 14 is arranged at the end of one of the drive shafts 210. A support arc plate 13 is arranged inside the drive chain 12. The rotating sprocket 11 meshes with the drive chain 12.

[0072] The second drive motor 14 drives the drive shaft 210 to rotate. The rotation of the drive shaft 210 drives the rotating sprocket 11 to rotate, thereby driving the drive chain 12 to rotate. The drive chain 12 can drive all the rotating sprockets 11 to rotate, that is, drive the drive shafts 210 to rotate at the same speed. Since the connecting shaft frame 29 is arc-shaped, in order for the drive chain 12 to play a transmission role, it is necessary to make the drive chain 12 in a taut state. In the present invention, the design of the support arc plate 13 can support the inside of the drive chain 12. In addition, the inner wall of the connecting cavity also supports the drive chain 12.

[0073] In the present invention, the soil is compacted by the ridging roller group 4. Among them, the ridging roller group 4 adopts the following preferred embodiment. The ridging roller group 4 includes an upper ridging roller 41 and a side ridging roller 42 arranged on the side of the upper ridging roller 41. The upper ridging roller 41, the side ridging roller 42 and the mounting shaft column 15 are coaxially arranged. The side ridging roller 42 is movably mounted on the upper ridging roller 41. The inner diameter of the end close to the upper ridging roller 41 is smaller than the inner diameter of the end of the side ridging roller 42 far from the upper ridging roller 41.

[0074] When the ridge spacing is adjusted and changed, the installation position of the corresponding side ridging roller 42 on the upper ridging roller 42 is also adjusted accordingly. Among them, the inner diameter of the end close to the upper ridging roller 41 is smaller than the inner diameter of the end of the side ridging roller 42 far from the upper ridging roller 41, in order to form a slope on the formed ridged heap 6 after compaction.

[0075] In summary, the main implementation process of the present invention is as follows:

[0076] Install the frame 1 on the tractor;

[0077] The first drive motor 34 drives the distance-adjusting base rod 31 to rotate. The limiting strip 35 limits the translation cylinder seat 32. Under the rotation of the distance-adjusting base rod 31, the translation cylinder seat 32 on the threaded section 33 is driven to translate, and the distance between the ridging blades 21 becomes larger, and the ridge spacing becomes larger, realizing the adjustment of the ridge spacing;

[0078] Adjust the installation position of the side ridging roller 42 on the upper ridging roller 42 so that the distance between the two ends of the side ridging roller 42 is exactly the preset ridge width;

[0079] Adjust the installation angle of the soil guiding plate 23 so that the end of the soil guiding plate 23 just faces the end of the ridging cavity wall 5;

[0080] Place the ridging roller set 4 in the soil and drive the tractor. The soil enters the soil pushing channel 22 from the side of the soil dividing tip plate 26. The second drive motor 14 drives the drive shaft 210 to rotate. The rotation of the drive shaft 210 drives the rotation of the rotating sprocket 11, thereby driving the rotation of the transmission chain 12. The transmission chain 12 can drive all the rotating sprockets 11 to rotate, drive the drive center 210 to rotate at the same speed, and drive the boosting impeller 24 to rotate. Under the boosting action of the boosting impeller 24, the soil is pushed out of the soil pushing channel 22 smoothly;

[0081] After the soil comes out of the soil pushing channel 22, it gradually moves forward a certain distance along the length direction of the ridge ditch 7 from the guide plate 25, and then enters the ridging roller set 4 through the soil guiding plate 23 for soil compaction and shaping.

[0082] In the present invention, the distance adjusting base rod 31 is on the extension line of the central axis of each ridging blade 21. Therefore, when the translation cylinder base 32 moves along the distance adjusting base rod 31, the distance between adjacent ridging blades 21 changes. However, the change range of the width inside the soil pushing channel 22 is not very different. Therefore, the width inside the soil pushing channel 22 tends to be equal everywhere, and the resistance received by the soil inside the soil pushing channel 22 is also a gradually changing process, and the influence caused by the resistance change caused by the change of the internal width of the pushing channel 22 is relatively small.

[0083] In addition, when the ridge distance becomes larger, the translation cylinder base 32 gradually moves outward along the distance adjusting base rod 31. During the process of the translation cylinder base 32 moving outward along the distance adjusting base rod 31, the guide plate 25 also moves along the direction parallel to the distance adjusting base rod 31, and the guide plate 25 gradually moves away from the soil guiding plate 23. At this time, the outlet of the soil pushing channel 22 for outputting soil outward is wider and the resistance received is smaller. That is to say, when the required ridge distance increases, the width of the soil to be ridged becomes smaller, the area and width of the ridge ditch 7 become larger, the width inside the soil pushing channel 22 becomes larger, and the outlet of the soil pushing channel 22 extending to the guide plate 25 also becomes larger, so that when the ridge distance becomes larger, the resistance received by the soil can be kept balanced, avoiding the situation where the resistance received during ridging increases correspondingly when the width of the ridging ridge ditch 7 becomes larger and the ridge distance becomes larger.

The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions within the essence and protection scope of the present application, and such modifications or equivalent substitutions should also be regarded as falling within the protection scope of the present application.
