Description

Technical Field

[0001] The present application belongs to the field of ridging machines, and specifically relates to a vibrating ridging machine. Technical Background

[0002] Land ridging is a traditional agricultural method 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] During the ridge forming process, a vibration pump is used to provide active suppression vibration force. Although the ridge can be vibrated and compacted, it is difficult to connect the power to the vibration pump because the compaction roller is always in a rotating working state. In addition, the vibration of the vibration pump is instantaneous vibration ridge compaction, that is, each time the vibration pump vibrates downward, it presses a compact ridge surface on the ridge, and then immediately starts the upward vibration process. Taking into account the periodic vibration of the vibration pump, loose ridge surfaces will be pressed out on both sides of the compacted ridge surface, which will result in the loose ridge surface and the compacted ridge surface being close to each other in the pressed ridge. Since the loose ridge surface is higher than the compacted ridge surface, the ridge surface is approximately serrated, resulting in a sudden change in the longitudinal strength of the pressed ridge surface. This ridge surface structure with a sudden change in longitudinal strength will affect the stability of the ridge surface strength. The ridge surface with a sudden change in longitudinal strength pressed out by the prior art, that is, the loose ridge surface is much more prominent than the compacted ridge surface, and the protruding loose ridge surface is easily damaged. Summary of the Invention

[0007] The purpose of this application is to address the ridge surface with sudden change in longitudinal strength pressed out in the prior art, that is, the loose ridge surface protrudes much more than the compact ridge surface, and the protruding loose ridge surface is easily damaged.

[0008] To achieve the above objectives, this application provides the following technical solutions:

[0009] A vibratory ridging machine comprises: a frame and a vibratory ridge pressing mechanism, the frame is provided with a driving member, the vibratory ridge pressing mechanism comprises a connecting plate, a vibrating shaft, a differential transmission member and a hollow roller, one end of the connecting plate is hinged to the frame, and the other end is rotatably provided with a vibrating shaft, the vibrating shaft is in transmission connection with the driving member, an eccentric block is provided on the vibrating shaft, and the hollow roller is sleeved on the vibrating shaft, and the differential transmission member is provided between the vibrating shaft and the hollow roller.

[0010] Preferably, it also includes a vibration damping component, which includes a first elastic member, a movable rod, a second elastic member and a mounting block, one end of the movable rod is connected to the frame through the first elastic member, and the other end is connected to the mounting block through the second elastic member, and the end of the vibration shaft is hinged to the mounting block.

[0011] Preferably, an adjusting rod is provided on the frame, one end of the adjusting rod is hinged to the frame, and the other end is hinged to the connecting plate.

[0012] Preferably, the adjustment rod includes a telescopic adjustment section and a vibration damping section.

[0013] Preferably, the differential transmission member is a planetary gear train.

[0014] Preferably, a tillage assembly is provided on the frame.

[0015] Preferably, a soil crushing assembly is rotatably provided on the frame and is located between the tillage assembly and the vibrating ridge pressing mechanism. The soil crushing assembly includes a soil crushing shaft and loosening teeth provided on the soil crushing shaft. The soil crushing shaft is rotatably provided on the frame and is transmission-connected to the driving member.

[0016] Preferably, the eccentric block is detachably connected to the vibration shaft.

[0017] Preferably, a plurality of the vibrating ridge pressing mechanisms are arranged at intervals along the traveling direction of the frame, and the plurality of the vibrating ridge pressing mechanisms are located in the same plane.

[0018] Preferably, there is an initial phase difference between the eccentric blocks of adjacent vibrating ridge pressing mechanisms, the interval between adjacent vibrating ridge pressing mechanisms is equal to the circumference of the hollow roller, and the initial phase difference is 180°.

[0019] Beneficial effects:

[0020] 1. When the eccentric block rotates, when it turns downward, that is, when the eccentric block deviates to the position half a circle below the plane of the vibration axis, gravity and centrifugal force together make the vibration axis and hollow roller gradually force downward to compact the ridge surface, and the closer the eccentric block is to the bottom, the greater the downward compacting force it produces. Conversely, the farther the eccentric block is from the bottom, the smaller the downward compacting force it produces. When it turns upward, that is, when the eccentric block deviates to the position half a circle above the plane of the vibration axis, centrifugal force gradually lifts the vibration axis and hollow roller upward, and the closer the eccentric block is to the top, the greater the upward lifting force it produces. Conversely, The further away the eccentric block is from directly above, the smaller the upward force it generates. The structural strength of the pressed ridge along the length direction is compact, sub-compact (the strength gradually decreases), loose (the ridge surface directly pressed by the rotation of the ridge-forming roller), and sub-compact (the strength gradually increases), which continuously cycles through four levels. For the ridges of the above structure, the longitudinal strength of the ridge surface is not sudden, but gradual. Compared with the ridge surface with sudden longitudinal strength pressed out by the prior art (that is, the loose ridge surface is much more prominent than the compact ridge surface, and the protruding loose ridge surface is easily damaged), this ridge surface structure with gradual longitudinal strength has stronger ridge surface strength stability.

[0021] 2. The vibrating shaft and the hollow roller are connected through a differential transmission member. The differential transmission member can be a planetary gear system or a bearing. The driving member drives the vibrating shaft to rotate. While the vibrating shaft rotates, the vibration force is transmitted to the hollow roller through the differential transmission member, so that the hollow roller vibrates and presses out the ridges. At the same time, the hollow roller can rely on the friction of the soil to rotate, so that the hollow roller can vibrate and press the ridges while there is a certain speed difference with the vibrating shaft, which is convenient for adjusting the vibration frequency and the hollow roller speed to reach a certain difference. At the same time, the vibration force can be transmitted to the hollow roller through the differential transmission member, so that the hollow roller vibrates and presses out the ridges.

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The following will further describe the technical solution of this application in conjunction with the drawings of the embodiments of this application, and this application is not limited to the following specific implementation methods.

[0033] It should be understood that the same or similar reference numerals in the drawings of the embodiments correspond to the same or similar components. In the description of this application, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom" and the like indicating an orientation or positional relationship, they are based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0034] In a specific embodiment of the present application, Figures 1 to 9As shown, there is a vibrating ridger, comprising: a frame 100 and a vibrating ridge pressing mechanism 200, the frame 100 can be a self-propelled frame that can provide power for travel, or it can be powered by other devices, the frame 100 is provided with a driving member 110, the driving member 110 can be a reducer that can be externally connected to the power of a tractor, or it can be any driving device that can directly or indirectly provide power, the vibrating ridge pressing mechanism 200 includes a connecting plate 210, a vibrating shaft 220, a differential transmission member 230 and a hollow roller 240, one end of the connecting plate 210 is hinged to the frame 100, and the other end is rotatably provided with a vibrating shaft 220, the vibrating shaft 220 is transmission-connected to the driving member 110, and an eccentric block 221 is provided on the vibrating shaft 220, and the eccentric block 221 is provided on the vibrating shaft 220 when the vibrating shaft 220 rotates. 21 generates a vibration force, and the vibration frequency of the vibration force is positively correlated with the rotational speed of the vibration shaft 220. The greater the rotational speed of the vibration shaft 220, the higher the vibration frequency of the vibration force. Conversely, the smaller the rotational speed of the vibration shaft 220, the lower the vibration frequency of the vibration force. When the eccentric block 221 rotates, there is an unbalanced centrifugal force. When it rotates upward, the centrifugal force lifts the vibration shaft 220 and the hollow roller 240 upward. When it rotates downward, gravity and centrifugal force together cause the vibration shaft 220 and the hollow roller 240 to force the ridge surface downward, completing the process of the vibration shaft 220 vibrating once, and the hollow roller 240 is sleeved on the vibration shaft 220. The differential transmission member 230 is provided between the vibration shaft 220 and the hollow roller 240. The differential transmission member 230 can be a planetary gear system or a reducer.

[0035] In a specific embodiment, the field soil is first broken up using tillage equipment. When the vibrating ridger of the present application performs ridging operations in the field, the tractor drives the frame 100 to move in the field and drives the vibration shaft 220 to rotate. The differential transmission member 230 can be a planetary gear system or a bearing. The driving member 110 drives the vibration shaft 220 to rotate. While the vibration shaft 220 rotates, the vibration force is transmitted to the hollow roller 240 through the differential transmission member 230, so that the hollow roller 240 vibrates to press out the ridges. At the same time, the hollow roller 240 can rely on the friction of the soil to rotate, so that the hollow roller 240 can vibrate and press the ridges while having a certain rotation speed with the vibration shaft 220. The difference is convenient for adjusting the vibration frequency and the rotation speed of the hollow roller 240 to reach a certain difference, and at the same time, the vibration force can be transmitted to the hollow roller 240 through the differential transmission member 230, so that the hollow roller 240 vibrates to press out the ridge. The rotation speed of the vibration shaft 220 and the rotation speed linear speed of the hollow roller 240 (that is, the speed of the frame traveling) are in a fixed speed ratio, that is, when the hollow roller 240 rotates one circle and presses out the ridge with the circumference length of the hollow roller 240, the number of circles of rotation of the vibration shaft 220 is determined, and the vibration frequency provided by the eccentric block 221 is constant, so that the structure of the pressed ridge is uniform, and the uniform structure has more stable mechanical properties and better appearance.

[0036] When the eccentric block 221 rotates, when it turns downward, that is, when the eccentric block 221 deviates to the position half a circle below the plane of the vibration shaft 220, gravity and centrifugal force together cause the vibration shaft 220 and the hollow roller 240 to gradually force the ridge surface downward, and the closer the eccentric block 221 is to the bottom, the greater the downward tamping force it generates. Conversely, the farther the eccentric block 221 is from the bottom, the smaller the downward tamping force it generates. When it turns upward, that is, when the eccentric block 221 deviates to the plane of the vibration shaft 220, the ridge surface is compacted. When the eccentric block 221 is in the position half a circle above the surface, the centrifugal force gradually lifts the vibration shaft 220 and the hollow roller 240 upward, and the closer the direction of the eccentric block 221 is to the top, the greater the upward force it generates. Conversely, the farther the direction of the eccentric block 221 is from the top, the smaller the upward force it generates. The vibration shaft 220 vibrates once, and the ridge structure pressed out by this process is that when the eccentric block 221 rotates downward, the force that tamps the ridge surface downward first gradually increases, reaches the maximum value, and then gradually decreases. The force is small, and when it reaches its maximum value, a most compact ridge surface will be pressed out. The most compact ridge surface is relative to the compact ridge surface pressed out when the vibration pump in the prior art vibrates downward instantaneously. Before and after the force reaches its maximum value, the compactness of the pressed ridge surface gradually decreases as it moves away from the most compact ridge surface. However, compared with the ridge surface directly pressed out by the non-vibrating ridging roller in the prior art, its strength is still higher, thereby achieving the structural strength of the pressed ridge along the length direction of compact, sub-compact (strength gradually decreases), loose (ridge surface directly pressed out by the rotation of the ridging roller), and sub-compact (strength gradually increases) four levels that are continuously cycled. The ridge structure pressed out by the above-mentioned application has a ridge surface that is a gradually wavy shape. In the ridge surface pressed out by the vibration of the prior art, the loose ridge surface is much more prominent than the compact ridge surface, forming a nearly sawtooth ridge surface. The protruding loose ridge surface is easily destroyed, and the longitudinal strength of the ridge surface pressed out by the present application is not sudden, but gradual. This ridge surface structure with gradual longitudinal strength has stronger ridge surface strength stability.

[0037] Beneficial effects:

[0038] 1. When the eccentric block 221 rotates, when it turns downward, that is, when the eccentric block 221 deflects to a position half a circle below the plane of the vibration shaft 220, gravity and centrifugal force together cause the vibration shaft 220 and the hollow roller 240 to gradually force downward to compact the ridge surface, and the closer the eccentric block 221 is to the bottom, the greater the downward compacting force it generates. Conversely, the farther the eccentric block 221 is from the bottom, the smaller the downward compacting force it generates. When it turns upward, that is, when the eccentric block 221 deflects to a position half a circle above the plane of the vibration shaft 220, the centrifugal force gradually lifts the vibration shaft 220 and the hollow roller 240 upward, and the closer the eccentric block 221 is to the top, the smaller the downward compacting force it generates. The larger the direction of the eccentric block 221 is, the greater the upward force it generates. Conversely, the farther away from the top, the smaller the upward force it generates. The structural strength of the pressed ridge along the length direction is compact, sub-compact (the strength gradually decreases), loose (the ridge surface directly pressed by the rotation of the ridging roller), sub-compact (the strength gradually increases), and the four levels are continuously cycled. For the ridges of the above structure, the longitudinal strength of the ridge surface is not sudden, but gradual. Compared with the ridge surface with sudden longitudinal strength pressed out by the prior art (that is, the loose ridge surface is much more prominent than the compact ridge surface, and the protruding loose ridge surface is easily damaged), this ridge surface structure with gradual longitudinal strength has stronger ridge surface strength stability.

[0039] 2. The vibration shaft and the hollow roller are connected through a differential transmission member. The differential transmission member can be a planetary gear system or a bearing. The driving member 110 drives the vibration shaft to rotate. While the vibration shaft rotates, the vibration force is transmitted to the hollow roller through the differential transmission member, so that the hollow roller vibrates and presses out the ridges. At the same time, the hollow roller can rely on the friction of the soil to rotate, so that the hollow roller can vibrate and press the ridges while there is a certain speed difference with the vibration shaft, which is convenient for adjusting the vibration frequency and the speed of the hollow roller to reach a certain difference. At the same time, the vibration force can be transmitted to the hollow roller through the differential transmission member, so that the hollow roller vibrates and presses out the ridges.

[0040] In the above implementation process, the eccentric block 221 generates an unbalanced centrifugal force when the vibration shaft 220 rotates to achieve vibration, but the vibration force is transmitted to the frame 100 along with the connection of the structure, and then transmitted to the tractor. In this process, the transmitted vibration force will increase the loss of the connection structure between the frame 100 and the connecting plate 210 or the frame 100, reducing the service life of the connection structure, and the transmitted vibration force will also affect the travel and service life of the tractor and the frame 100 itself. In a possible embodiment, a vibration damping component is also included, and the vibration damping component includes a first elastic member 31 0, a movable rod 320, a second elastic member 330 and a mounting block 340, the first elastic member 310 can be a mechanical spring, a gas / hydraulic spring or any elastic member that can automatically return to its position after being subjected to force, one end of the movable rod 320 is connected to the frame 100 through the first elastic member 310, and the other end is connected to the mounting block 340 through the second elastic member 330, the second elastic member 330 can be a mechanical spring, a gas / hydraulic spring or any elastic member that can automatically return to its position after being subjected to force, and the end of the vibration shaft 220 is hinged to the mounting block 340.

[0041] In one implementation process, the vibration force generated by the vibrating ridge pressing mechanism 200 will be partially transmitted to the vibration damping component. The transmission process is specifically as follows: the vibration force is first transmitted to the mounting block 340, and the mounting block 340 then transmits the vibration force to the second elastic member 330. The second elastic member 330 is preferably a spring. The second elastic member 330 is compressed or stretched by the vibration force, and the vibration force is converted into elastic potential energy. Then, through its own return deformation, the second elastic member 330 pulls one end of the movable rod 320 to swing in space, so that the gravitational potential energy and kinetic energy of the movable rod 320 are constantly changing. This process converts part of the elastic potential energy into the change in the gravitational potential energy and kinetic energy of the movable rod 320. This process completely converts this part of the elastic potential energy and no longer transmits it to the frame 100; the swinging of one end of the movable rod 320 in space will bring The other end of the movable rod 320 swings relatively, causing the end of the first elastic member 310 fixed to the movable rod 320 to continuously displace, while the end of the first elastic member 310 fixed to the frame 100 does not move. The first elastic member 310 will deform, and the gravitational potential energy and kinetic energy of the movable rod 320 will be converted into the elastic potential energy of the first elastic member 310 again. The deformed first elastic member 310 will generate elastic force to automatically return to its original position, driving the movable rod 320 to return to its original position. The return of the movable rod 320 is essentially a process in which the elastic potential energy of the first elastic member 310 and the elastic potential energy of the second elastic member 330 offset each other. Therefore, most of the vibration force transmitted to the vibration damping component is converted into the elastic potential energy of the two in this process, and finally completely offset. Only a small part of the vibration force is transmitted to the frame 100.

[0042] The above embodiment converts the vibration force transmitted to the frame 100 into the change of the gravitational potential energy of the movable rod 320 through the vibration damping component, thereby reducing the additional impact on the frame 100 caused by the vibration force, reducing the loss of the connection structure between the frame 100 and the connecting plate 210 or the frame 100, increasing the service life of the connection structure, and increasing the travel and service life of the tractor and the frame 100 itself; and can also improve the stability of the hollow roller 240 when vibrating and pressing the ridges.

[0043] In the above implementation process, the height of the hollow roller 240 is not adjustable, so the height of the pressed ridge is not adjustable, and the compactness of the pressed ridge cannot be changed, which makes it difficult to meet the requirements of different crops for ridge height and ridge compactness. In a possible embodiment, an adjusting rod 120 is provided on the frame 100. The adjusting rod 120 can be a hydraulic telescopic rod or any rod that can adjust the length. One end of the adjusting rod 120 is hinged to the frame 100, and the other end is hinged to the connecting plate 210. When the length of the adjusting rod 120 changes, the two ends of the adjusting rod 120 can adaptively rotate around the hinge points at both ends.

[0044] In a specific implementation process, the height of the soil surface is constant. By controlling the extension or shortening of the adjustment rod 120, the hollow roller 240 can be adjusted to rise or fall. When the height of the hollow roller 240 is increased, the height of the ridge pressed by the hollow roller 240 becomes higher. Since the height of the soil surface before pressing the ridge is constant, the ridge will become looser when the ridge height increases. When the height of the hollow roller 240 is decreased, the height of the ridge pressed by the hollow roller 240 becomes lower. Since the height of the soil surface before pressing the ridge is constant, the ridge will become tighter when the ridge height decreases.

[0045] Through the above process, the height of the hollow roller 240 can be adjusted, thereby adjusting the ridge height and the compactness of the ridge. In this way, according to the requirements of different crops for ridge height and compactness, ridges with different heights and compactness can be suppressed to meet the requirements of different crops for ridge height and compactness.

[0046] In the above implementation process, if the adjustment rod 120 adopts a conventional fixed-point adjustment structure, for example, it is locked when adjusted to a certain height, which will fix the hollow roller 240 in a certain position. This rigid fixed-point adjustment prevents the hollow roller 240 from vibrating, or can only drive the entire body to vibrate together, making the above-mentioned entire vibration ridge pressing process impossible to achieve. In a possible embodiment, the adjustment rod 120 includes a telescopic adjustment section 121 and a damping section 122. The telescopic adjustment section 121 can be telescopically adjusted in the form of a sleeved telescopic rod, or the length can be adjusted in a rigid fixed-point manner, while the damping section 122 uses elastic components such as springs or a structure that can be telescopic within a certain range for damping, so that the hollow roller 240 can vibrate up and down within a certain range, thereby realizing the vibration compaction of this application, and at the same time being able to adjust the height of the hollow roller 240 from the ground.

[0047] Furthermore, the adjusting rod 120 includes a telescopic adjusting section 121 and a vibration damping section 122. The telescopic adjusting section 121 can adjust its own length, thereby adjusting the height of the hollow roller 240. The vibration damping section 122 can play a buffering role when the hollow roller 240 vibrates and swings. The vibration damping section 122 contracts or stretches within a certain range as the hollow roller 240 vibrates up and down, thereby allowing the hollow roller 240 to vibrate freely without being fixed by the adjusting rod 120.

[0048] Furthermore, the differential transmission member 230 is a planetary gear train, which has the advantages of compact structure, low mass, large load-bearing capacity, wide power transmission range and transmission range, low operating noise, high efficiency, and long life. One arrangement of the planetary gear train is as follows: a ring gear is disposed within the hollow roller 240, a main gear is disposed at the end of the vibration shaft 220, and three planetary gears are disposed between the ring gear and the main gear. When the main gear rotates, it drives the planetary gears to rotate, and the planetary gears rotate on the ring gear, achieving differential rotation of the vibration shaft 220 and the hollow roller 240 and disengaging the rotation transmission around the same axis. At the same time, the planetary gear train is in hard contact, capable of transmitting the vibration force of the vibration shaft 220 to the hollow roller 240.

[0049] Furthermore, the frame 100 is provided with a tillage assembly 400, which can be a rotary tillage blade, a plow or a harrow, or any mechanical device that can till the land, so that the present application can realize active suppression of the broken soil blocks after one-time tillage, and finally press out a relatively compact ridge structure, avoiding the need for the tillage machinery to first till the field soil surface for pre-ridge treatment as in the above-mentioned implementation process, and can directly complete the tillage and ridge-forming operations at one time.

[0050] In the above embodiment, the soil conditions in the northwest region are poor and the land surface is easily compacted. When the tilling assembly 400 performs tillage operations on the compacted soil, large compacted soil blocks will be generated. If ridge formation and compaction are performed directly, large blocks of compacted soil will appear on the surface of the ridge, which will not only affect the structural stability of the ridge, but also affect subsequent ridge operations, such as planting and watering. In a possible embodiment, a soil crushing assembly 500 is rotatably provided on the frame 100 and is located between the tilling assembly 400 and the vibrating ridge pressing mechanism 200. The soil crushing assembly 500 includes a soil crushing shaft 510 and loosening teeth 520 provided on the soil crushing shaft 510. The soil crushing shaft 510 is rotatably provided on the frame 100. When large soil blocks appear after the tilling assembly 400 operates, the loosening teeth 520 on the rotating soil crushing shaft 510 can be inserted into the large soil blocks to crush the large soil blocks. The soil crushing shaft 510 is also connected to the driving member 110 in a transmission manner.

[0051] In one implementation process, when the tractor drives the frame 100 forward, the tilling assembly 400 performs tilling operations, turning most of the soil into loose clods, among which some large compacted clods appear. Then, the soil crushing shaft 510 rotates, and the loosening teeth 520 are inserted into the large clods, so that the large clods are crushed and squeezed into loose soil and small soil particles, avoiding the subsequent ridge pressing mechanism 200 from embedding large clods on the surface of the ridge, causing the surface structure of the ridge to be destroyed, thereby ensuring that the ridge structure pressed by this application is stable and beautiful, and the pressed ridge is not easy to be destroyed by subsequent ridge operation processes.

[0052] In the above implementation process, although the vibrating ridge pressing mechanism 200 achieves a ridge surface with a sudden change in longitudinal strength compared to the prior art, this ridge surface structure with a gradual change in longitudinal strength has a technical effect of stronger ridge surface strength stability, but the loose ridge surface still exists, and because the vibration force of the eccentric block 221 has a periodic up and down change, the loose ridge surface and the compacted ridge surface account for half. In a possible embodiment, the vibrating ridge pressing mechanism 200 is arranged at intervals along the traveling direction of the frame 100, and the multiple vibrating ridge pressing mechanisms 200 are located in the same plane. When vibration pressing is performed, the loose ridge surface pressed out of the ridge by the previous vibrating ridge pressing mechanism 200 along the traveling direction of the frame 100 will be vibrated and compacted by the next vibrating ridge pressing mechanism 200 along the traveling direction of the frame 100. The multiple vibrating ridge pressing mechanisms 200 located in the same plane can reduce the proportion of loose ridge surface on the ridge during operation, so that the ridge surface pressed out of the ridge in this application is more compact and has higher structural strength.

[0053] In an optimized implementation process, there is an initial phase difference between the eccentric blocks 221 of adjacent vibrating ridge pressing mechanisms 200, and the interval between adjacent vibrating ridge pressing mechanisms 200 is equal to the circumference of the hollow roller 240. This setting will realize the following process: the hollow roller 240 of the previous vibrating ridge pressing mechanism 200 vibrates downward ten times during one rotation to press out ten compacted ridge surfaces and ten loose ridge surfaces, which are arranged as compacted ridge surfaces and loose ridge surfaces cyclically arranged on a section of ridge with the circumference length of the hollow roller 240. If the initial phase difference between the eccentric block 221 of the next vibrating ridge pressing mechanism 200 and the eccentric block 221 of the previous vibrating ridge pressing mechanism 200 is 180°. When the next vibrating ridge pressing mechanism 200 moves to this section of ridge, it will press out ten compacted ridge surfaces and ten loose ridge surfaces, but the arrangement order of the loose ridge surfaces and the compacted ridge surfaces is cyclically distributed in this section of ridge. Through the above process, the position where the next vibrating ridge pressing mechanism 200 presses out the compacted ridge surface is exactly the position where the hollow roller 240 of the previous vibrating ridge pressing mechanism 200 presses out the loose ridge surface, so that the ridge surfaces of the pressed ridges are all the above-mentioned compacted ridge surfaces, avoiding the appearance of loose ridge surfaces, and achieving the best effect expected by this application.

[0054] In a more specific embodiment, when the vibratory ridger of the present application performs ridging operations in a field, a tractor drives the frame 100 to advance in the field, first using the tillage assembly 400 to break up the field soil, then the loosening teeth 520 on the soil crushing shaft 510 are inserted into large clods to crush the large clods together, and at the same time, the vibration shaft 220 is driven to rotate. While the vibration shaft 220 rotates, the vibration force is transmitted to the hollow roller 240 through the differential transmission member 230. The hollow roller 240 rotates by friction with the soil, thereby pressing out a ridge, and the vibration force generated by the vibration shaft 220 is transmitted to the hollow roller 240 through the differential transmission member 230, so that the hollow roller 240 vibrates up and down while rotating;

[0055] Before use, the height of the hollow roller 240 from the ground can be adjusted by adjusting the length of the telescopic adjustment section 121 of the adjustment rod 120, so as to adjust the height of the pressed ridge. When the eccentric block 221 rotates, when it turns downward, that is, when the eccentric block 221 deviates to the position half a circle below the plane of the vibration shaft 220, gravity and centrifugal force together cause the vibration shaft 220 and the hollow roller 240 to gradually force the ridge surface downward, and the closer the eccentric block 221 is to the bottom, the greater the downward tamping force it generates. Conversely, the farther the eccentric block 221 is from the bottom, the smaller the downward tamping force it generates. When the hollow roller 240 vibrates downward, the adjustment rod 120 The slow vibration section 122 of the adjusting rod 120 works, causing the hollow roller 240 to vibrate freely downward within a certain range. When it turns upward, that is, when the eccentric mass 221 deviates to a position half a circle above the plane of the vibration shaft 220, the centrifugal force gradually lifts the vibration shaft 220 and the hollow roller 240 upward, and the closer the direction of the eccentric mass 221 is to directly above, the greater the upward force it generates. When the hollow roller 240 is lifted upward, the slow vibration section 122 of the adjusting rod 120 works, causing the hollow roller 240 to vibrate upward within a certain range. Conversely, the farther the direction of the eccentric mass 221 is from directly above, the smaller the upward force it generates, thus completing the process of one vibration of the vibration shaft 220.

[0056] The structure of the ridge pressed out in this process is that when the eccentric block 221 rotates downward, the force for compacting the ridge surface gradually increases first, and then gradually decreases after reaching the maximum value. When the force reaches the maximum value, a most compact ridge surface is pressed out. The most compact ridge surface is relative to the compact ridge surface pressed out when the vibration pump in the prior art vibrates downward instantaneously. Before and after the force reaches the maximum value, the compactness of the pressed ridge surface gradually decreases as it moves away from the most compact ridge surface, but its strength is still higher than the ridge surface directly pressed out by the ridging roller, thereby realizing the pressed ridge along the length direction. The structural strength is in a continuous cycle of four levels: compact, sub-compact (strength gradually decreases), loose (ridge surface directly pressed out by the rotation of the ridging roller), and sub-compact (strength gradually increases). The ridge structure pressed out by the above-mentioned application has a ridge surface with a gradual wavy shape, while in the ridge surface pressed out by vibration in the prior art, the loose ridge surface is much more prominent than the compact ridge surface, forming an almost sawtooth ridge surface. The protruding loose ridge surface is easily damaged, while the longitudinal strength of the ridge surface pressed out by the present application is not sudden, but gradual. This ridge surface structure with gradual longitudinal strength has stronger ridge surface strength stability.
