Description

Technical Field

[0001] This invention relates to agricultural and forestry land reclamation and development technology, belonging to the field of engineering machinery, specifically to a bucket-type land reclamation device, a land reclamation machine, and its usage method. Background Technology

[0002] Vegetation clearing, agricultural and forestry reclamation, and the creation of forest firebreaks and firewalls are important operational links in land resource development, forest fire prevention infrastructure construction, and ecological management. This operation is carried out in a complex and ever-changing environment and involves the clearing, crushing, and targeted treatment of various vegetation such as shrubs, weeds, vines, and small and medium-sized trees. Some existing land reclamation equipment mainly focuses on cutting. For example, Chinese utility model patent CN219514557U discloses a new type of land reclamation machine cutter roller device. The disclosed content is as follows: the cutting roller has a circular tube and a mounting flange plate inside. The outer surface of the circular tube is welded with a cutter tooth seat, and cutter teeth are set on the cutter tooth seat. Through the new cutter teeth and their arrangement, the cutter teeth can be effectively mixed and combined, and the cutter teeth themselves can also rotate freely. However, its function is relatively simple, only performing cutting operations, and it has the problem of not being able to quickly clear some special vegetation. Taking the mass planting of some non-timber economic trees as an example, the fruit yield of trees such as palm trees will decline significantly after a certain number of years. Planters will clear these trees to make way for new trees. Existing land clearing equipment operates on vegetation by cutting action, but it has a weak ability to handle the root system and dense small branches of vegetation. Multiple operations with multiple machines are required. For example, additional bladed bucket equipment is needed to dig up tree roots or collect cutting debris. Multiple machines need to be used in combination, resulting in low work efficiency, poor mobility, difficulty in continuous operation, and unsuitability for some special working environments. Summary of the Invention

[0003] The purpose of this invention is to provide a bucket-type land reclamation device with a simple and compact structure, which realizes continuous shoveling and cutting operations, completes rapid land reclamation of the surrounding environment, has high mobility, reduces the use of traditional multi-machine operation, and is suitable for different working environments.

[0004] To achieve the above objectives, a bucket-type land reclamation device is provided, comprising: The top plate is supported, and corresponding side plates are fixed on both sides. The bucket assembly includes a bucket plate with an arc-shaped structure, a cutting edge fixed to the lower end of the bucket plate, and multiple bucket teeth arranged side by side on the cutting edge. The bucket plate is located between a pair of supporting side plates, and together with the supporting top plate, it forms a bucket structure with a certain volume; The cutting component, located at the rear of the bucket component, has a cutting drum that is rotatably connected between a pair of support side plates and has multiple cutting teeth on the cutting drum. The supporting top plate is driven to rotate circumferentially, which allows the bucket component and the cutting component to switch positions in the circumferential direction.

[0005] In some examples of the present invention, the cutting component further includes: a shaft; The shaft is coaxially connected to the cutting drum and rotatably connected to the support side plate at both ends. One end of the shaft extends out and is connected to the first drive assembly.

[0006] In some examples of the present invention, the shaft includes: The first shaft is rotatably mounted in the middle of the inner side of the cutting drum, and an eccentric block is provided on the first shaft; A pair of second shafts are fixedly connected to the cutting drum and located on both sides of the first shaft, and the second shafts are connected to the first drive assembly; The first axis and the second axis are connected by a connecting component; the connecting component is configured to controllably disconnect and fix the first axis and the second axis.

[0007] In some examples of the present invention, the connecting component is a clutch or a magnetic coupler; The supporting top plate is mounted on the slewing bearing and is equipped with shock-absorbing components.

[0008] In some examples of the present invention, the second shaft is provided with an axially arranged first hole and a radially arranged second hole connected to the first hole; An electric slip ring or rotary joint is installed on the end side of the second shaft; The control wires of the connecting assembly pass through the second hole and the first hole to connect to the slip ring or rotary joint and are then led out.

[0009] In some examples of the present invention, a pressure sensor is provided at the contact position between the bucket teeth and the bucket plate for obtaining the force exerted by the bucket teeth when in contact with the object; The pressure sensor is connected to the control unit via a wireless transmitter; The control component is connected to the first drive component and the connection component, and controls their corresponding actions.

[0010] In some examples of the present invention, the support side plate is provided with vertically arranged strip grooves; After the shaft passes through the strip groove, it is rotatably mounted on the support slide plate. The support slide plate is moved to the support side plate by the second drive assembly. The first drive component is installed on the support slide plate. When the support slide plate moves to the upper and lower extreme positions, the horizontal tangent at the lower end of the cutting roller can be higher than the lower end of the support side plate and lower than the lower end of the support side plate respectively. The control unit is connected to the second drive assembly and controls its corresponding actions.

[0011] In some examples of the present invention, the lower end of the support side plate is provided with a slipper; A guide plate is hinged to the rear side of the supporting top plate and located above the cutting drum. The guide plate is configured to guide the cut material. The outer side of the supporting side plate is provided with a cover plate that covers the first drive assembly and the second drive assembly.

[0012] The present invention also aims to provide a bucket-type land reclamation machine, which can drive the land reclamation device to adjust its position by moving the mechanical arm on the main unit, and realize the circumferential switching of the bucket component and the cutting component, so as to realize continuous operation of shoveling and cutting. The multi-functional operation enables rapid processing of materials and is suitable for some special working environments.

[0013] A bucket-type land reclamation machine, characterized in that it comprises: The aforementioned bucket-type land reclamation device also includes: The support bracket is connected to the support top plate by a controlled slewing bearing; A detection component used to measure the height of the workpiece being cut; The mobile host is movably connected to the support frame via a robotic arm; shock-absorbing components are installed between the support frame and the robotic arm.

[0014] The present invention also aims to provide a method for using a bucket-type land reclamation machine, which allows the bucket component and the cutting component to be switched in the circumferential direction and work together according to the height of the trees to complete the pushing down of branches of different heights and the digging of tree roots. This method can effectively reduce the cumbersome operation caused by multiple machines and improve the efficiency of tree debris processing.

[0015] A method for using a bucket-type land reclamation machine includes the following steps: S1, determine the height of the tree. When the tree height is not less than the maximum lifting height of the mobile host's robotic arm, perform the cutting operation: Once the location of the tree is determined to be unobstructed, the support top plate is driven to rotate, positioning the cutting component in front of that location. The position of the moving main unit is adjusted so that the cutting roller contacts the tree at a suitable height. The cutting roller is then driven to rotate, cutting the tree to a depth of not less than 1 / 2 of the tree's diameter to form a cut. The position of the moving main unit is then readjusted, and the bucket component is switched to the front by rotating the support top plate, with the bucket teeth positioned above the tree cut, causing it to tilt forward to the corresponding location. After the trees are felled, the cutting component is switched to the front, and the cutting roller rotates to cut and break the trees from top to bottom until they are broken down to the roots close to the ground. S2, when the tree height is less than the maximum lifting height of the mobile host's robotic arm, the cutting component rotates to cut and break the tree directly from top to bottom until it reaches the tree roots close to the ground; S3, after the trees are cut and broken, adjust the circumferential position of the bucket component and the cutting component. First, dig the tree roots from the ground with the bucket teeth, and then use the cutting roller to cut and break them. When the bucket teeth cannot directly dig the tree roots from the ground, the connecting components are controlled to fix the first shaft and the second shaft. When the cutting drum rotates, the eccentric block on the first shaft will generate a strong eccentric vibration effect, causing the support side plate and bucket components to vibrate synchronously. The continuous vibration impact causes the bucket teeth to act on the tree roots to dig.

[0016] Compared with existing technologies, this bucket-type land reclamation device has the following advantages: 1. The bucket component and the cutting component are integrated and installed on the support top plate. The circumferential rotation of the support top plate allows the bucket component and the cutting component to switch circumferential positions, thus realizing continuous shoveling and cutting operations, completing rapid material processing, with high mobility, reducing the use of traditional multi-tool operation, and suitable for different working environments; 2. By setting an eccentric block on the first shaft, the first shaft can be disengaged from and fixedly connected to the second shaft through the connecting assembly. When the first shaft and the second shaft are fixedly connected, strong eccentric vibration is generated, causing the support side plate and bucket components to vibrate synchronously. Thus, the switching between the two working modes of normal shoveling and enhanced shoveling is realized. The continuous vibration impact is beneficial for the bucket teeth to act on the shoveled object, which can be applied to different working environments and improve land reclamation efficiency. 3. The second drive component drives the support slide plate to move, thereby adjusting the height of the cutting drum so that the horizontal tangent at the lower end of the cutting drum is lower than the lower end of the support side plate. Therefore, when this bucket-type land reclamation device is pushed horizontally, the front bucket component can clean and collect the soft material on the upper layer of soil, and the rear cutting drum can cut and clean the hard material on the lower layer of soil. This can greatly improve land reclamation efficiency and is suitable for land reclamation operations in different terrains. Attached Figure Description

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, this bucket-type land reclamation device includes: The top support plate 11 is driven to rotate circumferentially, and corresponding side support plates 12 are fixed on both sides. The bucket component 200 includes a bucket plate 21 with an arc-shaped structure, a cutting edge 23 fixed to the lower end of the bucket plate 21, and a plurality of bucket teeth 22 arranged side by side on the cutting edge 23. The bucket plate 21 has an arc-shaped structure and is located between a pair of supporting side plates 12, forming a bucket structure with a certain volume; The cutting component 300, located at the rear of the bucket component 200, has a cutting drum 31 that is rotatably connected between a pair of support side plates 12 and is configured to cut the material. Among them, the supporting top plate 11 is driven to rotate circumferentially, so that the bucket component 200 and the cutting component 300 can switch circumferentially. Specifically, the top support plate 11 can rotate 360° in the circumference via the slewing bearing 13, and the two sides are fixed with support side plates 12 by welding, all of which are made of ultra-high strength plates; The bucket component 200 is configured for shoveling materials during land reclamation. The arc-shaped bucket plate 21 is welded and fixed, forming a bucket structure with the upper support top plate 11 and a pair of side support side plates 12 to hold a certain amount of material. The bucket teeth 22 have ultra-high strength and can directly act on hard objects such as vegetation and gravel. The bucket teeth 22 can be fixed and disassembled on the cutting edge plate 23 by bolts, fixing seats, etc. The cutting component 300 is configured for cutting operations during the land reclamation process. The cutting drum 31 is located on the rear side of the bucket component 200 and is connected to the first drive assembly 41 for driving. The cutting drum 31 is provided with cutting teeth 311, and the distribution of the cutting teeth 311 can be arranged according to the technical solution of a new type of land reclamation machine cutting tooth drum device disclosed by the applicant in CN219514557U. When this bucket-type land reclamation device is in use, the supporting top plate 11 is driven to rotate for circumferential adjustment, so that the bucket component 200 and the cutting component 300 are respectively positioned at the front to perform different operations. When the bucket component 200 is positioned at the front, the bucket component 200 performs actions such as pushing, digging, and collecting, for example, pushing down tree branches, digging at tree roots, and pushing on the soil surface to collect debris. When the cutting component 300 is positioned at the front, the cutting component 300 performs cutting and crushing actions, for example, cutting and crushing tree branches.

[0021] In some examples of the present invention, such as Figure 4 As shown, the cutting component 300 also includes a shaft 32; Shaft 32 is coaxially connected to cutting drum 31 and rotatably connected to support side plate 12 at both ends. One end of shaft 32 extends out and is connected to first drive assembly 41. Specifically, the first drive assembly 41 may be a hydraulic motor, a transmission component connected to the output end of the hydraulic motor, and a transmission wheel mounted on the end side of the shaft 32. Furthermore, such as Figure 4 As shown, the shaft 32 includes: The first shaft 321 is rotatably mounted in the middle of the inner side of the cutting drum 31, and an eccentric block 33 is provided on the first shaft 321; A pair of second shafts 322 are fixedly connected to the cutting drum 31 and are located on both sides of the first shaft 321 respectively. The second shafts 322 are connected to the first drive assembly 41. The first axis 321 and the second axis 322 are connected by a connecting component 34; the connecting component 34 is configured to controllably disengage and fix the first axis 321 and the second axis 322. Furthermore, the connecting component 34 is a clutch or a magnetic coupler; A controlled slewing bearing 13 is connected between the supporting top plate 11 and the supporting bracket 100; a shock-absorbing component is provided between the supporting bracket 100 and the robotic arm; Furthermore, the second shaft 322 is provided with an axially arranged first hole and a radially arranged second hole connected to the first hole; An electric slip ring 35 or a rotary joint is installed on the end side of the second shaft 322; The control wires of the connecting assembly 34 pass through the second hole and the first hole and are connected to the slip ring 35 or the rotary joint and led out. Specifically, the shaft 32 is divided into a first shaft 321 and a second shaft 322. The first shaft 321 is rotatably mounted inside the cutting drum 31 via bearings, and an eccentric block 33 for generating eccentric vibration is fixedly mounted on it. The second shaft 322 is fixedly connected to the end side of the cutting drum 31 and is rotatably mounted on the support side plate 12 via bearings. During initial normal use, the connecting component 34 enables the first shaft 321 and the second shaft 322 to rotate relative to each other, i.e., they are in a segmented disengaged state. The first drive component 41 drives the second shaft 322 and the cutting drum 31 to rotate, thus performing normal cutting operations. When the bucket component 200 encounters significant resistance while acting on the object being shoveled, the connecting assembly 34 enables the first shaft 321 and the second shaft 322 to be fixedly connected, i.e., in an integrally coupled state. The first drive assembly 41 drives the second shaft 322, the first shaft 321, and the cutting drum 31 to rotate. The eccentric block 33 on the first shaft 321 will generate a strong eccentric vibration effect, causing the support side plate 12 and the bucket component 200 to vibrate synchronously. The continuous vibration impact is beneficial for the bucket teeth 22 to act on the object being shoveled, thereby improving the shoveling operation effect. The connecting component 34 is a clutch or magnetic coupler, which can perform contact or non-contact transmission and is easy to control. It is existing technology and will not be described further here. The shock absorption component includes a shock absorber and a mounting bracket, which can reduce the vibration of this bucket-type land reclamation device acting on the installation position (mechanical arm). Both the clutch and the magnetic coupler are connected to the control components for easy control. When hydraulic control is used for switching, the control wire (pipeline) passes through the second hole and the first hole to connect to the rotary joint and is then led out to connect to the hydraulic source. When electronic control is used for switching, the control wire passes through the second hole and the first hole to connect to the electric slip ring 35 and is then led out. This example demonstrates that by setting an eccentric block 33 on the first shaft 321, the first shaft 321 can be disengaged from and fixedly connected to the second shaft 322, enabling the switching between normal shoveling and enhanced shoveling working modes. This allows it to be suitable for different working environments, avoids obstruction of the bucket component 200 on the shoveled material, and prevents the need for additional surrounding soil shoveling, thereby improving land reclamation efficiency.

[0022] Furthermore, a pressure sensor is provided at the contact position between the bucket teeth 22 and the bucket plate 21 to obtain the force exerted by the bucket teeth 22 when in contact with the object. The pressure sensor is connected to the control unit via a wireless transmitter; The control unit is connected to the first drive assembly 41 and the connection assembly 34, and controls their corresponding actions.

[0023] Specifically, when there are many bucket teeth 22, pressure sensors can be installed on several bucket teeth 22. When the contact force between the bucket tooth 22 and the hard object increases, the pressure sensor acquires the pressure signal and transmits the signal to the control unit through the wireless transmitter. The control unit includes a controller and an analysis component. The grouping component can analyze the pressure signal, that is, eliminate unreasonable or abnormal data, and then compare it with the set pressure threshold. When the pressure on the bucket teeth 22 reaches the set pressure threshold, the controller controls the first drive assembly 41 and the connecting assembly 34 to perform corresponding actions, such as controlling the first drive assembly 41 to start and the connecting assembly 34 to fix the first shaft 321 and the second shaft 322 to connect. The continuous vibration and impact improve the effect of the bucket teeth 22 on the shoveled material. When the pressure on the bucket teeth 22 does not reach the set pressure threshold, the controller controls the first drive assembly 41 to shut down and the connecting assembly 34 to disengage the first shaft 321 from the second shaft 322. At this time, the bucket component 200 performs normal shoveling operations.

[0024] In some examples of the present invention, such as Figure 5 , Figure 6 As shown, the supporting side plate 12 is provided with vertically arranged strip grooves 121; After the shaft 32 passes through the strip groove 121, it is rotatably mounted on the support slide plate 51. The support slide plate 51 is moved on the support side plate 12 by the second drive assembly 42. Among them, the first drive component 41 is installed on the support slide plate 51. When the support slide plate 51 moves to the upper and lower extreme positions, the horizontal tangent at the lower end of the cutting roller 31 can be higher than the lower end of the support side plate 12 and lower than the lower end of the support side plate 12 respectively. The control unit is connected to the second drive assembly 42 and controls its corresponding actions.

[0025] Specifically, the length of the strip groove 121 determines the vertical height of the cutting component 300. When the support slide plate 51 moves to the upper limit position, the cutting roller 31 can be located between a pair of support side plates 12 without affecting the operation of the bucket component 200. When the support slide plate 51 moves to the lower limit position, the lower end of the cutting roller 31 can extend to suit special working environments. A folded sealing film is provided between one end of the shaft 32 and the strip groove 121. This sealing film can ensure that the shaft 32 is always sealed with the strip groove 121 during movement, so as to prevent foreign objects from entering and affecting the operation of the second drive assembly 42. The support slide plate 51 is slidably mounted on the support side plate 12 via a slide rail. The slide rail can be an integrated linear slide rail or a T-shaped slider and slide groove. The second drive assembly 42 can be a hydraulic motor fixed on the support side plate 12 and a screw rod 52 fixedly connected to the output end of the hydraulic motor. The screw rod 52 is threadedly connected to the lug seat installed on the support slide plate 51. When the hydraulic motor starts and drives the screw rod 52 to rotate, the support slide plate 51 can move axially on the support side plate 12, and the first drive assembly 41 located on the support slide plate 51 can normally drive the cutting drum 31 to rotate. When clearing land, the bucket component 200 can be switched to the front to scoop materials in a flat pushing manner, which is convenient for collecting debris. However, when in complex terrain such as slopes or unleveled wasteland, the soil may be uneven or soft on top and hard on the bottom. The bucket component 200 will encounter a large obstruction when encountering hard soil layers and will not be able to clear them quickly. Although the cutting component 300 can be switched to the front to perform flat pushing cutting and crushing, the crushed debris will be thrown to the front by the cutting roller 31 and accumulate, affecting the forward movement. In this example, the second drive component 42 drives the support slide plate 51 to move, thereby adjusting the height of the cutting roller 31 so that the horizontal tangent at the lower end of the cutting roller 31 is lower than the lower end of the support side plate 12. Therefore, when this bucket-type land reclamation device pushes horizontally, as... Figure 6 As shown, the front bucket component 200 can clean and collect soft materials on the upper layer of soil, while the rear cutting roller 31 can cut and clean hard materials in the lower layer of soil. Therefore, it can greatly improve land reclamation efficiency and is suitable for land reclamation operations in different terrains.

[0026] In some examples of the present invention, such as Figure 2 , Figure 3 As shown, the lower end of the support side plate 12 is provided with a sliding shoe 60; A guide plate 14 is hinged to the rear side of the supporting top plate 11 and is located above the cutting drum 31. The guide plate 14 is configured to guide the cut material. The outer side of the supporting side plate 12 is provided with a surrounding plate 15 that covers the first drive assembly 41 and the second drive assembly 42; Specifically, the slipper 60 is fixedly installed on the support side plate 12 by bolts, which can prevent the lower end of the support side plate 12 from directly contacting the soil and being damaged; the guide plate 14 is hinged to the support top plate 11 and can be adjusted in angle to control the discharge direction of the debris. The supporting side plate 12 has a cover structure 15, which can be disassembled and installed to protect the first drive assembly 41 and the second drive assembly 42 on the inside.

[0027] This invention relates to a bucket-type land reclamation machine, comprising: the aforementioned bucket-type land reclamation device, and further comprising: A controlled slewing bearing 13 is connected between the support bracket 100 and the support top plate 11; A detection component used to measure the height of the workpiece being cut; The mobile host is movably connected to the support bracket 100 via a robotic arm; a shock-absorbing component is provided between the support bracket 100 and the robotic arm; Specifically, a slewing bearing 13 is provided between the supporting top plate 11 and the supporting bracket 100, and the supporting top plate 11 is driven to rotate by hydraulic means; the supporting bracket 100 has multiple brackets, each of which can be hinged to the robotic arm. The robotic arm is divided into a large arm and a small arm, and can be adjusted in various angles and positions by hydraulic means. The mobile host can be a loader, excavator, or other vehicle suitable for land reclamation operations. The detection component can be a distance and elevation sensor mounted on a robotic arm or mobile host, which acquires the distance from the base measuring end to the workpiece through the distance sensor. The horizontal elevation angle from the base measuring end to the workpiece is obtained through an elevation angle sensor. The height of the workpiece being cut The calculation formula is: The specific steps for using this bucket-type land reclamation device are as follows: S1, as Figure 7 As shown, the height of the tree is determined, and the cutting operation is performed when the tree height is not less than the maximum lifting height of the mobile host's robotic arm. Once the location of the tree without obstructions is determined, the supporting top plate 11 is driven to rotate, positioning the cutting component 300 in front of that location. The position of the moving host is adjusted so that the cutting roller 31 contacts the tree at a suitable height. The cutting roller 31 is driven to rotate, cutting the tree with a cutting depth of not less than 1 / 2 of the tree diameter to form a cut. The position of the moving host is readjusted, and the bucket component 200 is switched to the front by rotating the supporting top plate 11, with the bucket teeth 22 positioned above the tree cut, causing it to tilt forward to the corresponding location. After the tree is knocked down, the cutting component 300 is switched to the front, and the cutting roller 31 rotates to cut and break the tree from top to bottom until it is broken down to the roots close to the ground. S2, as Figure 8 As shown, when the tree height is less than the maximum lifting height of the mobile host's robotic arm, the cutting component 300 rotates directly from top to bottom to cut and break the tree until it is broken down to the tree roots close to the ground. S3, as Figure 9 As shown, after the tree is cut and crushed, the cutting roller 31 can penetrate to a certain depth into the ground, or the circumferential position of the bucket component 200 and the cutting component 300 can be adjusted so that the tree roots are first dug out from the ground by the bucket teeth 22, and then the cutting roller 31 is used for cutting and crushing. When the bucket teeth 22 cannot directly dig the tree roots from the ground, the connecting assembly 34 is controlled to fix the first shaft 321 and the second shaft 322. When the cutting drum 31 rotates, the eccentric block 33 on the first shaft 321 will generate a strong eccentric vibration effect, causing the support side plate 12 and the bucket component 200 to vibrate synchronously. The continuous vibration impact causes the bucket teeth 22 to act on the tree roots to dig.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this invention, and various combinations can be made to the various technical features and structures proposed in this invention, without exceeding the protection scope of this invention, which is determined by the appended claims.

A detection component used to measure the height of the workpiece being cut; The mobile host is movably connected to the support bracket (100) via a robotic arm; a shock-absorbing component is provided between the support bracket (100) and the robotic arm.

10. A method of using the bucket-type land reclamation machine according to claim 9, characterized in that, Specifically, the following steps are included: S1, determine the height of the tree. When the tree height is not less than the maximum lifting height of the mobile host's robotic arm, perform the cutting operation: Once the location of the tree is determined to be unobstructed, the support plate (11) is driven to rotate so that the cutting component (300) is positioned in front of that location. The position of the moving host is adjusted so that the cutting roller (31) contacts the tree at a suitable height. The cutting roller (31) is driven to rotate to cut the tree with a cutting depth of not less than 1 / 2 of the tree diameter to form a cut. The position of the moving host is readjusted, and the bucket component (200) is switched to the front by rotating the support plate (11). The bucket teeth (22) are positioned above the tree cut so that they tilt forward to the corresponding location. After the tree is knocked down, the cutting component (300) is switched to the front, and the cutting roller (31) rotates to cut and break the tree from top to bottom until it is broken down to the roots close to the ground. S2, when the height of the tree is less than the maximum lifting height of the robotic arm of the mobile host, the cutting component (300) rotates to cut and break the tree directly from top to bottom until it reaches the tree root close to the ground; S3, after the tree is cut and crushed, adjust the circumferential position of the bucket component (200) and the cutting component (300), first dig the tree roots from the ground through the bucket teeth (22), and then use the cutting roller (31) to cut and crush them; When the bucket teeth (22) cannot directly dig the tree roots from the ground, the connecting assembly (34) is controlled to fix the first shaft (321) and the second shaft (322). When the cutting drum (31) rotates, the eccentric block (33) on the first shaft (321) will generate a strong eccentric vibration effect, causing the support side plate (12) and the bucket component (200) to vibrate synchronously. The continuous vibration impact causes the bucket teeth (22) to act on the tree roots to dig.
