Description

Technical Field

[0001] The present application belongs to the field of agricultural machinery, and specifically relates to an adjustable vibrating ridge pressing device. Technical Background

[0002] Land ridging is a traditional agricultural practice that improves soil structure and promotes crop growth by forming mounds of soil (ridges) above the ground and furrows (furrows) between ridges.

[0003] Ridging before planting improves soil temperature and moisture management, increases surface area, and enhances photosynthetic efficiency. It also combats drought and flooding, inhibits weed growth, facilitates mechanized harvesting, and improves crop yield and quality. Ridging improves soil quality, light, ventilation, photosynthetic efficiency, and fertilizer and water utilization.

[0004] Common ridging machines generally use the weight of the ridging device to passively press out ridges in the soil. This ridging method has the problem that the structure of the ridges pressed out is unstable, and the ridge structure is easily destroyed when subsequent operations are performed on the ridges, thereby affecting the function of the ridges.

[0005] In the prior art, there is a utility model patent with application number 202223328383.4, entitled "A Ridge Forming and Compacting Device." The patent provides a device that can actively compact ridges, which to some extent solves the problem of unstable and easily damaged ridge structures in the prior art. However, the following problems still exist:

[0006] The loose soil is directly ridged. Although the height of the compacting roller can be adjusted by the adjusting rod, the compaction degree of the ridges pressed out by the vibration is actually adjusted. Lowering the compacting roller height will make the ridge height shorter, thus making it more compact. Conversely, raising the compacting roller height will make the ridge height higher, thus making it looser. During adjustment, the ridge height is inversely proportional to the compaction degree, and the looseness of the soil cannot be adjusted at the same ridge height. Summary of the Invention

[0007] The purpose of this application is to address the problem in the prior art that the ridge height is inversely proportional to the compaction degree during adjustment, and the looseness of the soil cannot be adjusted at the same ridge height.

[0032] Please refer to Figures 1 to 9 In one embodiment of the present application, there is an adjustable vibrating ridge pressing device, comprising

[0033] The frame 100 and the soil-fixing roller assembly 200 and the vibrating compacting assembly 300 are sequentially arranged on the rear side of the frame 100. The soil-fixing roller assembly 200 is used to initially gather the soil into a loose ridge shape. The soil-fixing roller assembly 200 can be any existing ridging tool. The vibrating compacting assembly 300 further vibrates and compacts the loose ridge shape into a compact ridge structure. The frame 100 is provided with a first driving member 110, a mounting frame 120 and an adjustable scraper plate 150. The adjustable scraper plate 150 is used to scrape the loose soil in the field to a required thickness. The soil-fixing roller assembly 200 can be rotatably arranged on the frame 100. The soil-fixing roller assembly 200 presses the soil of a specified thickness into a ridge shape for the first time. The thicker the soil thickness, the compacter the ridge shape. Similarly, the thinner the soil thickness, the tighter the ridge shape. , the looser the ridge shape, and the soil fixing assembly is transmission-connected to the first driving member 110, the vibrating compacting assembly 300 is hinged to the mounting frame 120, and the vibrating compacting assembly 300 further presses the ridge shape into a tighter high-strength ridge through active vibration based on the compactness of the first pressed ridge shape. The adjustable scraper plate 150 is located between the frame 100 and the soil fixing roller assembly, and the upper end of the adjustable scraper plate 150 is hinged to the frame 100. The adjustable scraper plate 150 and the frame 100 can be locked at multiple locations to adjust the scraping angle of the adjustable scraper plate 150. By locking the adjustable scraper plate 150 with different points, the height of the lower end of the adjustable scraper plate 150 from the ground is adjusted, thereby adjusting the soil thickness when pressing the ridge and adjusting the tightness of the pressed ridge.

[0034] In a specific implementation process, the tractor tows the frame 100 to operate in the field. If a looser ridge is required, the adjustable scraper board 150 is locked with a lower point, and the adjustable scraper board 150 is adjusted and fixed in a lower position. When the frame 100 moves, the adjustable scraper board 150 in the lower position can scrape the soil to a lower thickness. When the soil-fixing roller assembly 200 is working, the soil of lower thickness is pressed into a ridge shape. The height of the pressed ridge remains unchanged, but the ridge shape will become looser. On the contrary, if a tighter ridge shape is required, the adjustable scraper board 150 is locked with a higher point, and the adjustable scraper board 150 is adjusted and fixed in a higher position. When the frame 100 moves, the adjustable scraper board 150 in the higher position can scrape the soil to a higher thickness. When the soil-fixing roller assembly 200 is working, the soil of higher thickness is pressed into a ridge shape. The height of the pressed ridge remains unchanged, but the ridge shape will become tighter. Finally, the vibration of the vibrating compaction component 300 can further compact the extruded ridge into a ground ridge. Since the vibration force changes suddenly and the frequency is high, the vibrating compaction component 300 can compact the surface of the extruded ridge each time it vibrates, while the inside of the ridge is still relatively loose. Since the compaction degree of the ridge shape is adjusted differently, the vibrating compaction component 300 further compacts the ridge shape with different compaction degrees, so the compaction degree of the final extruded ridge is also adjusted accordingly.

[0035] Beneficial effect: The present application adjusts the fixed point by adjusting the adjustable scraper plate 150, the adjustable scraper plate 150 is located between the frame 100 and the soil-fixing roller assembly, and the upper end of the adjustable scraper plate 150 is hinged to the frame 100, the adjustable scraper plate 150 and the frame 100 can be locked at multiple locations to adjust the scraping angle of the adjustable scraper plate 150, and the height of the lower end of the adjustable scraper plate 150 from the ground is adjusted by locking the adjustable scraper plate 150 with different points, so as to press the ridges. The soil thickness can adjust the compactness of the ridge pressed out by the soil-fixing roller assembly 200 during operation, and the compacted ridge surface pressed out by the vibrating compaction assembly 300 is based on the ridge shape. The compacter the ridge shape, the greater the supporting force of the soil. The ridge surface is pressed into a compacted ridge surface by the vibration force of the vibrating compaction assembly 300 and the supporting force provided by the soil. Therefore, the compacter the ridge shape, the compacter the ridge surface. Adjusting the adjustable scraper plate 150 can adjust the compactness of the ridge and the ridge surface at the same ridge height.

[0036] Furthermore, the frame 100 is provided with a plurality of adjustment holes 170, and the adjustable scraper blade 150 is provided with a support rod 160. One end of the support rod 160 is hinged to the upper side of the adjustable scraper blade 150 facing away from the ridge, as shown in FIG8 . The other end of the support rod 160 is provided with a hook 161, and the hook 161 can be locked with the adjustment hole 170. The plurality of adjustment holes 170 are arranged in a straight line. When the hook 161 is hooked to different adjustment holes 170, the lower end of the adjustable scraper blade 150 can be maintained at different heights, thereby achieving the height adjustment of the adjustable scraper blade 150 in a relatively simple manner.

[0037] In the above process, if a vibration mode with external power is used, since the vibration compaction assembly 300 needs to rotate while vibrating, it is difficult to connect to the power source of most vibration modes, such as a vibration pump, and the rotation speed of the hollow roller 340 is consistent with the vibration frequency of the vibration shaft 320. In a possible embodiment, the vibration compaction assembly 300 includes two swing plates 310, a vibration shaft 320, an eccentric block 330, a hollow roller 340 and a second driving member 350. One end of the two swing plates 310 is respectively hinged to the two ends of the mounting frame 120, and the vibration shaft 320 is rotatably arranged between the other ends of the two swing plates 310. The eccentric block 330 is arranged on the vibration shaft 320, and the hollow roller 340 is rotatably sleeved on the vibration shaft 320. The second driving member 350 is arranged on the swing plate 310 and is transmission-connected to the vibration shaft 320. At this time, the second driving member 350 transmits power to the vibration shaft 320. The rotation of the vibration shaft 320 will drive the eccentric block 330 to rotate eccentrically. When the eccentric block 330 rotates around the vibration shaft 320, a vibration force will be generated. At this time, the hollow roller 340 is sleeved on the vibration shaft 320 and rotates around the vibration shaft 320 by relying on the friction force when it contacts the soil. The way the eccentric block 330 provides the vibration force only requires external power to the vibration shaft 320. Since the vibration shaft 320 passes through the hollow roller 340, it is very easy to connect power to the vibration shaft 320. A transmission part can be set at one end of the vibration shaft 320, and the transmission of rotation between the hollow roller 340 and the vibration shaft 320 is disengaged. The specific disengagement form can be to set a bearing between the two, and the hollow roller 340 and the vibration shaft 320 are respectively connected to the inner and outer rings of the bearing, so as to realize the differential operation of the rotation of the hollow roller 340 and the vibration frequency of the vibration shaft 320, that is, the vibration shaft 320 does not vibrate up and down once when the hollow roller 340 rotates one circle, but the rotation of the hollow roller 340 and the vibration shaft 320 is not synchronized, and does not affect the transmission of the vibration force of the vibration shaft 320 to the hollow roller 340.

[0038] In the above process, if the soil-fixing roller assembly 200 is misaligned with the vibrating compacting assembly 300, the strength of the two sides of the ridges pressed out by the vibrating compacting assembly 300 will be asymmetric, resulting in one side of the pressed ridge being too tight and having weak air permeability, and the other side being too loose, and the ridge structure strength on this side is too weak. In one possible embodiment, the soil-fixing roller assembly 200 includes a rotating shaft 210 and an intermediate ridge-forming roller 220, and the intermediate ridge-forming roller 220 is a hollow cylindrical roller, and the two ends of the cylindrical roller are cones extending outward. The rotating shaft 210 is rotatably arranged on the frame 100 and is connected to the second driving member 350. The transmission method between the second driving member 350 and the rotating shaft 210 is preferably pulley transmission. The pulley transmission has better adaptability and can well adapt to the harsh environment of field operations. The intermediate ridging roller 220 is arranged on the rotating shaft 210. The intermediate ridging roller 220 can be fixed on the rotating shaft 210, or can be any type of concentrically matched on the rotating shaft 210, and is arranged in opposition to the hollow roller 340.

[0039] In a specific implementation process, since the intermediate ridging roller 220 and the hollow roller 340 are arranged in opposition, the intermediate ridging roller 220 of the present application first rotates to press out a relatively compact preliminary ridge shape, and then the hollow roller 340 is aligned with the outer contour of the preliminary ridge shape. After the hollow roller 340 actively vibrates and compacts, the compacted ridge structure strength is symmetrical, thereby avoiding the above-mentioned problems.

[0040] In the above process, if on both sides of the ridge opened by the soil-fixing roller assembly 200, only the inner side of the ridge close to the soil-fixing roller assembly 200 is compacted, while the outer side is prone to collapse, the soil collapsed in the ridge will hinder the vibration compaction assembly 300 from performing the vibration ridge pressing operation, and the soil collapses in the outer ridge. The soil collapsed on this side will lift up the hollow roller 340 on this side when the hollow roller 340 vibrates, resulting in asymmetric strength on both sides of the ridge pressed by the vibration ridge pressing assembly 300, thereby causing the inner side of the pressed ridge to be too compact and the air permeability to be weakened, and the outer side to be too loose. The strength of the ridge structure on the outer side is too weak, and only the soil on the outer side collapses, which will also make the force on the hollow roller 340 unbalanced, making the hollow roller 340 40 is subjected to torsion, resulting in a decrease in the service life of the hollow roller 340. In a possible embodiment, the soil-fixing roller assembly 200 also includes two tapered rollers 230, and the two tapered rollers 230 are spaced apart at both ends of the intermediate ridge-forming roller 220. There is a ridge gap between the tapered roller 230 and the end of the intermediate ridge-forming roller 220. The above arrangement realizes that the ridges on both sides of the ridge pressed out by the soil-fixing roller assembly 200 are inverted trapezoidal, wherein the tapered roller 230 stabilizes the outer side of the ridge, thereby avoiding the above-mentioned problem of unbalanced force on the hollow roller 340 due to the collapse of the outer side of the ridge, causing the connection of the hollow roller 340 to be subjected to torsion, resulting in a decrease in the service life of the hollow roller 340.

[0041] In the above process, if the ridge opened by the soil-fixing roller assembly 200 collapses and excess soil appears in the ridge, the excess soil will hinder the vibration compaction assembly 300 from performing the vibration ridge compaction operation. For example, if excess soil appears in only one side of the ridge, the excess soil will lift up the hollow roller 340 on that side when the hollow roller 340 vibrates, resulting in asymmetric strength on both sides of the ridge pressed out by the vibration compaction assembly 300, thereby causing one side of the pressed ridge to be too tight and the air permeability to be weakened, and the other side to be too loose, and the ridge on that side If the structural strength is too weak and the soil collapses on only one side, the force on the hollow roller 340 will be unbalanced, and the connection of the hollow roller 340 will be subjected to torsion, resulting in a shorter service life of the hollow roller 340. In a possible embodiment, at least two ditching members 130 are provided on the frame 100, and the two ditching members 130 are arranged in alignment with the ridge gap. The ditching members 130 push the soil in the ridge away to avoid excess soil in the ridge that hinders the vibration compaction assembly 300 from performing the vibration ridge compacting operation.

[0042] In the above process, the same problem of soil collapse in the ditch occurs as above. Only the collapsed soil can lift the hollow roller 340, which will also make the force on the hollow roller 340 unbalanced, and the connection of the hollow roller 340 will be subjected to torsion, resulting in a shorter service life of the hollow roller 340. In a possible embodiment, an anti-torsion bar 360 is connected between the two swing plates 310. The function of the anti-torsion bar 360 is to make the two swing plates 310 swing up and down synchronously, so as to avoid the above-mentioned torsion being transmitted to the hinge of the swing plate 310, thereby reducing the life of the fragile hinge point. The above process significantly increases the service life of the hinge connection point of the swing plate 310.

[0043] During the above implementation process, the swing plate 310 swings up and down with the hollow roller 340, which will cause the anti-torsion bar 360 to be subjected to additional force, reducing the service life of the anti-torsion bar 360, and transmitting additional vibration force to the frame 100, which will damage the service life of the frame 100. Once the structure of the frame 100 resonates, the welding points of the frame 100 will be broken. In a possible embodiment, at least one shock-absorbing spring 140 is connected between the mounting frame 120 and the anti-torsion bar 360. The shock-absorbing spring 140 is vertically arranged. When the swing plate 310 swings up and down, the vertically arranged shock-absorbing spring 140 can convert the potential energy of the swinging plate 310 into the deformation of the shock-absorbing spring 140. The deformation of the shock-absorbing spring 140 will further buffer the potential energy generated by the swinging of the swing plate 310.

[0044] During the above implementation process, the unilaterally driven rotary tillage blade group 420 will cause uneven force on both sides of the rotary tilled soil, which will to a certain extent lead to different degrees of crushing of the soil on both sides of the frame 100. In a possible embodiment, it also includes a rotary tillage assembly 400 arranged on the frame 100, and the rotary tillage assembly 400 includes a transmission member 410 and two rotary tillage blade groups 420 connected to both ends of the transmission member 410. One end of the rotary tillage blade group 420 is arranged on the transmission member 410, and the other end is rotatably arranged on the frame 100. The above arrangement realizes the direct rotary tillage and soil crushing operations and ridge compaction operations through this application, and the two symmetrically arranged rotary tillage blade groups 420 can achieve consistent conditions on both sides of the tilled soil, provide symmetrical soil conditions for ridge formation, and further ensure the strength symmetry of the ridges pressed out by this application.

[0045] Furthermore, in the above implementation process, the transmission member 410 is located between the two rotary tillage assemblies 400, where the soil cannot be turned over and crushed, and the impact of unbroken soil blocks will damage the transmission member 410. The transmission member 410 is provided with a protective shovel 430, and the protective shovel 430 is vertically arranged and faces the moving direction of the frame 100. The setting of the protective shovel 430 protects the transmission member 410 from being hit by unbroken soil blocks, and can also cultivate the dead corner between the two rotary tillage assemblies 400, thereby achieving the cultivating effect of a plow.

[0046] In a specific implementation process, the tractor tows the frame 100 to operate in the field. If a looser ridge is required, the adjustable scraper board 150 is locked with a lower point, and the adjustable scraper board 150 is adjusted and fixed in a lower position. When the frame 100 moves, the adjustable scraper board 150 in the lower position can scrape the soil to a lower thickness. When the soil-fixing roller assembly 200 is working, the soil of lower thickness is pressed into a ridge shape. The height of the pressed ridge remains unchanged, but the ridge shape will become looser. On the contrary, if a tighter ridge shape is required, the adjustable scraper board 150 is locked with a higher point, and the adjustable scraper board 150 is adjusted and fixed in a higher position. When the frame 100 moves, the adjustable scraper board 150 in the higher position can scrape the soil to a higher thickness. When the soil-fixing roller assembly 200 is working, the soil of higher thickness is pressed into a ridge shape. The height of the pressed ridge remains unchanged, but the ridge shape will become tighter. As shown in FIG8 , a plurality of adjustment holes 170 are arranged in sequence along a straight line. When the hook 161 is hooked on different adjustment holes 170, the lower end of the adjustable scraper plate 150 can be kept at different heights, thereby achieving the adjustment of the height of the adjustable scraper plate 150 in a relatively simple manner. Finally, the vibrating compacting component 300 can further compact the pressed ridge into a ridge through vibration. Since the vibration force changes suddenly and the frequency is high, the vibrating compacting component 300 can compact the surface of the pressed ridge each time it vibrates, while the inside of the ridge is still relatively loose. Since the compaction degree of the ridge is adjusted differently, the vibrating compacting component 300 further compacts the ridges with different compaction degrees. At this time, the second driving member 350 transmits power The vibration shaft 320 rotates, driving the eccentric mass 330 to rotate eccentrically. This rotation generates a vibration force around the vibration shaft 320. The hollow roller 340, mounted on the vibration shaft 320, rotates around the vibration shaft 320 by virtue of friction from the soil. The eccentric mass 330 provides the vibration force simply by connecting an external power source to the vibration shaft 320. Since the vibration shaft 320 passes through the hollow roller 340, connecting the power source to the vibration shaft 320 is very easy. Furthermore, the hollow roller 340 is decoupled from the vibration shaft 320, achieving a differential speed between the rotation of the hollow roller 340 and the vibration frequency of the vibration shaft 320. This means that the vibration shaft 320 does not vibrate up and down once for each rotation of the hollow roller 340. Therefore, the compaction of the final ridge is also adjusted by the adjustable scraper blade 150.

[0047] Obviously, the above embodiments of the present application are merely examples for the purpose of clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, other variations or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
