Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, specifically to a pioneering device for adjusting the front and rear door panels. Background Technology

[0002] The development of wasteland, the clearing of shrubs in courtyards, and the establishment of forest firebreaks all require the clearing of some trees and shrubs.

[0003] Manual clearing is not only inefficient but also extremely dangerous, especially with thorny plants. Current methods involve installing clearing devices on loaders and skid steer loaders for rapid clearing, using a rotating cutting drum to break up and clear thorns and bushes. However, the following problems remain: 1. To prevent material from being thrown and splashing after cutting, a baffle is often installed on the back of the cutting drum. This baffle is fixed and cannot be adjusted for finer cutting of trees; 2. Clearing devices have a relatively limited function. For more complex working environments, simple cutting is not suitable. For example, when clearing tall or tough trees or bushes, raising or adjusting the angle of the cutting drum still results in insufficient cutting force. Furthermore, additional equipment is needed to grip and transport the cut trees. Utility Model Content

[0004] The purpose of this utility model is to provide a pioneering device with adjustable front and rear door panels. It has a simple and compact structure and can not only adjust the size and throwing direction of the material after cutting, but also prevent the flying of cutting chips. It is suitable for cutting large-diameter trees.

[0005] To achieve the above objectives, this front and rear door panel adjustment device includes: a mounting on a robotic arm. The supporting frame has a cutting component at the bottom that rotates and cuts the tree. The front door assembly and the rear door assembly are mounted on the support frame and are arranged accordingly on the periphery of the cutting assembly. The front door assembly has a front door panel, the upper part of which is rotatably connected to the support frame, and the middle part is driven to rotate or positioned; the rear door assembly has a rear door panel, the upper part of which is rotatably connected to the support frame, and the middle part is driven to rotate. The support frame has an arc-shaped liner near the cutting component. The connection points between the front door panel, the rear door panel and the support frame are located on both sides of the liner, and the surface near the cutting component is an arc-shaped surface.

[0006] In some examples of this utility model, the end of the robotic arm is rotatably connected to one side of the upper part of the hanger via a central shaft; The other end of the upper part of the bracket is fixedly connected or connected to the main hydraulic cylinder so that the bracket can rotate around the central axis, and the support frame is installed at the lower end of the bracket.

[0007] In some examples of this utility model, a finger-clamping assembly is also included; the finger-clamping assembly has; The first clip is fixedly installed on one side of the support frame; The second clamping finger is rotatably mounted on the central shaft at its upper end and connected to the first hydraulic cylinder in the middle for driving rotation. The first hydraulic cylinder is connected to the controller and extends or retracts under control.

[0008] In some examples of this utility model, the upper end of the support frame is provided with a plurality of horizontally spaced through holes; The lower end of the bracket is installed on the through hole by bolts.

[0009] In some examples of this utility model, the bracket is slidably connected to the support frame via a slide rail; The lower end of the bracket is provided with an ear seat, and a helical rod with a horizontally arranged axis is provided on the support frame; the two ends of the helical rod are rotatably supported, one end is driven to rotate, and the middle part is threadedly connected to the ear seat.

[0010] In some examples of this invention, the rear door assembly also has a second hydraulic cylinder; The second hydraulic cylinder is rotatably mounted on the support frame at one end and rotatably connected to the middle of the rear door panel at the other end. The second hydraulic cylinder is connected to the controller and extends or retracts under control.

[0011] In some examples of this invention, the front door assembly includes a third hydraulic cylinder; The third hydraulic cylinder is rotatably mounted on the support frame at one end and rotatably connected to the middle of the front door panel at the other end. The third hydraulic cylinder is connected to the controller and extends or retracts under control.

[0012] In some examples of this utility model, the support frame is provided with a plurality of positioning holes arranged in an arc shape with the upper end of the front door panel as the center; The positioning pin passes through the front door panel and the positioning hole to fix the front door panel to the support frame.

[0013] In some examples of this utility model, the cutting assembly has: The cutting roller is rotatably mounted on the support frame and has multiple cutting teeth on its circumference. The drive unit is connected to the support shaft on the end side of the cutting drum via a transmission assembly.

[0014] In some examples of this utility model, the lower end of the support frame is provided with a slipper that can contact the ground.

[0015] Compared with existing technologies, in this front and rear door panel adjustment pioneering device, when the lower end of the rear door panel is away from the cutting component, most of the material can be thrown out from the rear door panel; when the lower end of the rear door panel is close to the cutting component, most of the material will be thrown out from the direction of the front door component, and the material will be cut into smaller pieces. The size of the material after cutting and the direction of throwing can be adjusted by changing the position of the rear door panel. When the lower end of the front door panel is close to the cutting component, it can prevent the cutting debris from splashing. When the lower end of the front door panel is away from the cutting component, the circumference of the cutting roller will increase the contact with the tree, which is suitable for cutting large-diameter trees. Because of the clamping component, the tree can be clamped and its position adjusted without affecting the operation of the cutting component, so that the cutting component has good cutting force; or after the cutting is completed, the tree can be clamped to facilitate transportation and site cleanup, thus adding more functions.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, the front and rear door panel adjustment device includes: a mechanical arm 10 mounted on the front and rear door panels. The support frame 30 has a cutting component 50 at the bottom that rotates and cuts the tree. The front door assembly 40 and the rear door assembly 70 are mounted on the support frame 30 and are arranged accordingly on the periphery of the cutting assembly 50. The front door assembly 40 has a front door panel 43, the upper end of which is rotatably connected to the support frame 30, and the middle part is driven to rotate or positioned and installed; the rear door assembly 70 has a rear door panel 73, the upper end of which is rotatably connected to the support frame 30, and the middle part is driven to rotate. Among them, an arc-shaped liner 32 is provided inside the support frame 30 near the cutting component 50. The connection points between the front door panel 43, the rear door panel 73 and the support frame 30 are located on both sides of the liner 32, and the surface near the cutting component 50 is an arc-shaped surface. Specifically, the robotic arm 10 can be the excavator arm, which can flexibly move this land reclamation device to various positions in space; The support frame 30 can be a frame structure formed by welding, bolting or other methods of steel plates. It has strong rigidity. The cutting component 50 at the bottom of the support frame 30 can be controlled to rotate at high speed to break trees. The front door panel 43 can be rotatably mounted on the support frame 30 via the first pin 41, and the rear door panel 73 can be rotatably mounted on the support frame 30 via the second pin 71. Relative to the cutting assembly 50, the front door panel 43 is biased to the upper front side, and the rear door panel 73 is biased to the lower rear side. The connection points between the front door panel 43, the rear door panel 73 and the support frame 30 are located on both sides of the liner 32, and the surface near the cutting assembly 50 is an arc-shaped surface, which allows the cut material to smoothly transition from the rear door panel 73 and the liner 32 to the front door panel 43 for ejection, avoiding large turns that would affect the ejection force of the material. When using this front and rear door panel adjustment device, first adjust the position of the support frame 30 by using the robotic arm 10 so that the cutting component 50 is arranged horizontally and attached to the corresponding ground. Adjust the rotation angle of the front door panel 43 and the rear door panel 73, such as... Figure 3 As shown, when the middle part of the rear door panel 73 is driven to rise, the lower end of the rear door panel 73 will move away from the cutting assembly 50. After the cutting assembly 50 rotates and cuts, larger materials can be thrown out from the rear door panel 73. For example, when the rear door panel 73 is fully opened, most of the materials will be thrown out from the rear door panel 73. When the middle part of the rear door panel 73 is driven to lower, the lower end of the rear door panel 73 will move closer to the cutting assembly 50. After the cutting assembly 50 rotates and cuts, most of the materials will be thrown out towards the front door assembly 40 as the cutting assembly 50 rotates. And because the material spends more time on the cutting assembly 50, the thrown material will be more fragmented. Therefore, by changing the position of the rear door panel 73, the size of the material after cutting and the throwing direction can be adjusted. When the lower end of the current door panel 43 is close to the cutting assembly 50, it can prevent cutting debris from flying. When the lower end of the current door panel 43 is far away from the cutting assembly 50, the circumference of the cutting roller 51 will increase the contact with the tree, which is suitable for cutting large-diameter trees.

[0020] In some examples of this utility model, such as Figure 1 As shown, the end of the robotic arm 10 is rotatably connected to one side of the upper part of the hanger 20 via the central shaft 21; The other end of the upper part of the bracket 20 is fixedly connected to or connected to the main hydraulic cylinder so that the bracket 20 can rotate around the central axis 21, and the support frame 30 is installed at the lower end of the bracket 20. Specifically, when the other end of the upper part of the hanger 20 is fixedly connected, the support frame 30 and the robotic arm 10 are fixedly arranged; When the other end of the upper part of the bracket 20 is connected to the main hydraulic cylinder, one end of the main hydraulic cylinder can be rotatably mounted on the robotic arm 10 or other support arm. At this time, after the main hydraulic cylinder extends and retracts, it can drive the support frame 30 to adjust the angle relative to the robotic arm 10 to suit different cutting actions.

[0021] In some examples of this utility model, such as Figure 1 , Figure 4 , Figure 5 As shown, the front and rear door panel adjustment device also includes a finger clamping assembly; The finger clamp assembly has; The first clip 61 is fixedly installed on one side of the support frame 30; The second clamping finger 62 is rotatably mounted on the central shaft 21 at its upper end and connected to the first hydraulic cylinder 63 in the middle for driving rotation. The first hydraulic cylinder 63 is connected to the controller and extends and retracts under control. Specifically, the first clamping finger 61 can be fixedly connected to the support frame 30 by bolts, and the clamping surface is inclined to match the second clamping finger 62; the second clamping finger 62 is driven by the first hydraulic cylinder 63 to unfold and close. In this example, the gripper assembly is initially closed, which does not affect the operation of the cutting assembly 50. In some complex working environments, when the cutting assembly 50 cannot cut directly or cutting is inconvenient, the first hydraulic cylinder 63 is activated, which drives the second gripper 62 to unfold and then close as the position of the robotic arm 10 is adjusted, thus clamping and adjusting the position of the tree, giving the cutting assembly 50 good cutting force. Alternatively, after cutting is completed, the gripper assembly unfolds and closes to clamp the tree for easy transport and site cleanup. The connection between the bracket 20 and the support frame 30 can be a fixed structure or an adjustable structure. When a fixed structure is used, such as Figure 5 As shown, the upper end of the support frame 30 is provided with a plurality of horizontally spaced through holes 31; The lower end of the bracket 20 is mounted on the through hole 31 by bolts; Specifically, before cutting, a suitable through hole 31 is selected to assemble the support frame 30 onto the hanger 20. In this example, the support frame 30 cannot be adjusted in real time during use. When an adjustable structure is used, the bracket 20 is slidably connected to the support frame 30 via a slide rail; The lower end of the hanger 20 is provided with an ear seat, and the support frame 30 is provided with a helical rod arranged horizontally along the axis; The screw rod is rotatably supported at both ends, with one end being driven to rotate and the middle part threadedly connected to the lug seat; Specifically, the screw rod can be driven by a hydraulic motor. After the screw rod rotates, the support frame 30 can move on the bracket seat 20 via the slide rail. In this example, by adjusting the position of the support frame 30 on the bracket seat 20, not only can the position of the cutting component 50 be adjusted to suit cutting at different positions, but the clamping force between the first clamping finger 61 and the second clamping finger 62 can also be adjusted to suit the clamping action of different trees. For example, when the support frame 30 moves on the bracket seat 20 and the first clamping finger 61 moves away from the second clamping finger 62, after the first hydraulic cylinder 63 is activated, the second clamping finger 62 needs to rotate at a larger angle, and the clamping force decreases. When the first clamping finger 61 moves closer to the second clamping finger 62, after the first hydraulic cylinder 63 is activated, the second clamping finger 62 needs to rotate at a smaller angle, and the clamping force increases.

[0022] In some examples of this utility model, such as Figure 3 As shown, the rear door assembly 70 also has a second hydraulic cylinder 72; The second hydraulic cylinder 72 is rotatably mounted on the support frame 30 at one end and rotatably connected to the middle of the rear door panel 73 at the other end. The second hydraulic cylinder 72 is connected to the controller and extends or retracts under control. Specifically, the second hydraulic cylinder 72 can be located inside the support frame 30 to avoid damage; The controller is an electro-hydraulic control system, which can control the flow of corresponding hydraulic oil to achieve real-time adjustment of the rear door panel 73 during cutting operations; Furthermore, the front door assembly 40 may have the same structure as the rear door assembly 70, for example, including a third hydraulic cylinder, which is controlled by a controller, with one end rotatably mounted on the support frame 30 and the other end rotatably connected to the middle of the front door panel 43. Alternatively, the front door assembly 40 can be fixed, such as... Figure 3 As shown, at the initial stage of use, the location is determined according to the usage environment. At this time, the support frame 30 is provided with multiple positioning holes 42 arranged in an arc shape with the upper end of the front door panel 43 as the center. After the positioning pin passes through the front door panel 43 and the positioning hole 42, it fixes the front door panel 43 to the support frame 30.

[0023] In some examples of this utility model, such as Figure 2 As shown, the cutting assembly 50 has: A cutting roller 51 is rotatably mounted on a support frame 30, and has multiple cutting teeth 52 on its circumference. The drive unit 57 is connected to the support shaft on the end side of the cutting drum 51 via a transmission assembly; Specifically, the axis of the cutting roller 51 is arranged horizontally, and support shafts extend to both sides at both ends. The support shafts are rotatably mounted on the support frame 30 through bearings and fixed seats 53. The drive unit 57 can be a hydraulic motor and is installed inside the support frame 30 to avoid contact with trees and damage. The transmission assembly can have a drive wheel 56, a transmission belt 55, and a driven wheel 54. That is, the drive wheel 56 is fixedly installed at the output end of the drive unit 57, and the driven wheel 54 is fixedly installed on the support shaft on the end side of the cutting drum 51. The drive wheel 56 and the driven wheel 54 are driven by the transmission belt 55 wrapped around its outer side. The transmission assembly is equipped with a protective cover to prevent damage from contact with trees; the cutting teeth 52 on the cutting roller 51 can be arranged in multiple spirals to effectively cut the soil and vegetation below ground level.

[0024] In some examples of this utility model, such as Figure 1 As shown, the lower end of the support frame 30 is provided with a sliding shoe 80 that can contact the ground; Specifically, the slipper 80 provides a stable fulcrum for the support frame 30 and prevents the cutting assembly 50 from directly contacting the ground.

[0025] When using this front and rear door panel adjustment device, first adjust the position of the support frame 30 by using the robotic arm 10 so that the cutting component 50 is arranged horizontally and attached to the corresponding ground. Adjust the rotation angle of the front door panel 43 and the rear door panel 73. When the middle of the rear door panel 73 is driven to rise, the lower end of the rear door panel 73 will move away from the cutting assembly 50. After the cutting assembly 50 rotates and cuts, larger materials can be thrown out from the rear door panel 73. When the middle of the rear door panel 73 is driven to lower, the lower end of the rear door panel 73 will move closer to the cutting assembly 50. Most of the materials after the cutting assembly 50 rotates and cuts will be thrown out towards the front door assembly 40 as the cutting assembly 50 rotates. Moreover, because the material spends more time on the cutting assembly 50, the thrown material will be more fragmented. When the lower end of the current door panel 43 is close to the cutting assembly 50, it can prevent cutting debris from flying. When the lower end of the current door panel 43 is far away from the cutting assembly 50, the circumference of the cutting roller 51 will increase the contact with the tree, which is suitable for cutting large-diameter trees. When the cutting assembly 50 cannot cut directly or cutting is inconvenient, the first hydraulic cylinder 63 is activated, which drives the second gripper 62 to unfold and then close as the position of the robotic arm 10 is adjusted, thus completing the clamping and position adjustment of the tree, so that the cutting assembly 50 has good cutting force; or after the cutting is completed, the gripper assembly unfolds and closes to clamp the tree for easy transportation and site cleanup.

[0026] The foregoing description, with reference to preferred embodiments, details an exemplary implementation of the front and rear door panel adjustment device proposed by this utility model. 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 utility model, and various combinations can be made to the various technical features and structures proposed by this utility model without exceeding the protection scope of this utility model, which is determined by the appended claims.
