Description

Technical Field

[0001] This invention relates to the field of forestry logging machinery and equipment technology, and in particular to a logging head clamping and conveying device. Background Technology

[0002] Logging is a management activity involving forests and trees, including four types: primary felling, thinning felling, regeneration felling, and low-yield forest transformation felling. Logging is one of the basic processes in timber production. It involves felling trees according to the purpose and requirements of forestry management, including thinning felling before the trees mature and primary felling of mature and over-mature forests. In forestry production, logging and regeneration are equally important and closely integrated. Logging should not only consider the needs of timber but also pay attention to the full utilization of forest resources, the economic benefits of timber harvesting and transportation, and the restoration of forest resources to facilitate long-term management and ensure that logging is conducive to regeneration. When carrying out forest clearing and logging work, workers will use chainsaws to cut down trees.

[0003] Existing technology, such as Chinese Patent CN 216164022 U, discloses a four-link spine-type main structure logging head for forestry engineering machinery. It includes a frame assembly, with a side-cutting blade body rotatably connected to the front of the frame assembly. Side-cutting blade uprights are fixedly connected to adjacent sides of the side-cutting blade body, and an upper cutting blade is fixedly connected to the top rear end of the side-cutting blade uprights. Chainsaw rotating mechanisms are fixedly connected to both sides of the front end of the frame assembly, and chainsaw assemblies are fixedly connected to the top of the output shafts of the chainsaw rotating mechanisms. Feed roller rotating shafts are installed inside each chainsaw assembly, and hydraulic cylinders are rotatably connected to both sides of the front end of the frame assembly. This four-link spine-type main structure logging head for forestry engineering machinery uses hydraulic rods to push the side-cutting blade body to clamp the tree trunk, and the chainsaw rotating mechanism drives the chainsaw assembly to rotate, breaking the bark of the trunk and allowing the bark to enter through the left and right feed rollers. However, the logging head with a four-link spine-type main structure used in this forestry engineering machinery has a complex timber clamping mechanism and is not conducive to axial centering of the timber during logging operations. Therefore, it is not conducive to clamping the timber when logging larger diameter timber, which is not conducive to the later maintenance and use of the equipment and is not conducive to efficient timber logging operations. Summary of the Invention

[0004] To address the problems of complex structure and poor clamping effect of existing logging equipment timber clamping devices.

[0005] The technical solution of the present invention:

[0006] A logging head clamping and conveying device is provided, including a frame, a power component, an auxiliary wheel assembly, a clamping assembly, and a transmission and detection assembly. One side of the frame has a V-shaped structure, and the frame is welded from steel plates to support and mount all functional components of the device. The power component is embedded in one side of the V-shaped structure of the frame, at its center. The power component includes a protective housing and a drive roller. A hydraulic drive assembly is installed inside the protective housing to drive the rotation of the drive roller. The auxiliary wheel assembly includes a transition plate and an auxiliary rotating wheel. The auxiliary rotating wheel is rotatably connected to the transition plate, and the transition plate is fixedly connected to the frame. The auxiliary wheel assembly is embedded in the other side of the V-shaped structure of the frame, opposite to the power component. The axes of the auxiliary rotating wheel and the drive roller form a V-shape, thus achieving a better clamping effect on the timber. The clamping assembly includes a connecting shaft, a first connecting arm, a second connecting arm, a connecting swing arm, a clamping component, and an adjusting connecting rod. The connecting shaft is connected to the end of the frame that is V-shaped and furthest from the power component. One end of the second connecting arm is fixedly connected to one end of the connecting shaft, and the other end is rotatably connected to the clamping component. One end of the first connecting arm is fixedly connected to the other end of the connecting shaft, and the other end is rotatably connected to the clamping component. The middle part of the connecting swing arm is rotatably connected to the connecting shaft. One end of the connecting swing arm is connected to the clamping component via the adjusting connecting rod. The end of the connecting swing arm furthest from the adjusting connecting rod is connected to the frame. The transmission detection assembly is used to assist in detecting the displacement of the wood during its movement relative to the device. It includes a support frame and a pressure roller. The support frame is fixedly connected to the frame, and the pressure roller is connected to the support frame. The pressure roller is located in the middle of the inner side of the V-shaped structure of the frame, close to the auxiliary wheel assembly and the power component.

[0007] A hydraulic cylinder is installed between the end of the first connecting arm, which is fixedly connected to the connecting shaft, and the frame to drive the first connecting arm and connecting shaft, and the second connecting arm to rotate relative to the frame. The first connecting arm, the second connecting arm, the connecting swing arm, the adjusting connecting rod, and the clamping component form a four-bar linkage structure. The hydraulic cylinder drives the first connecting arm and connecting shaft, and the second connecting arm to rotate relative to the frame, causing the clamping component to move closer to or further away from the auxiliary rotating wheel and the drive roller. That is, the hydraulic cylinder drives the clamping component, the auxiliary rotating wheel, and the drive roller to clamp the wood. After clamping, the drive roller can move the clamping position of the device on the wood, and the transmission detection component can accurately detect the displacement of the wood.

[0008] Furthermore, in this invention, a logging head clamping and conveying device is provided. To improve the applicability of the clamping component in this device when logging timber of different diameters, thereby improving the efficiency of timber logging operations, the two ends of the adjusting connecting rod are respectively connected to the clamping component and the connecting swing arm. The adjusting connecting rod can adjust the distance between the clamping component and the connecting swing arm, thereby adjusting the clamping effect of the clamping component, the auxiliary wheel component, and the power component.

[0009] Furthermore, in order to improve the structural strength of the clamping component and thus ensure that the device can operate stably for a long time, the clamping component of the present invention includes a clamping wheel and a clamping shell. The clamping wheel is sleeved on the inner side of the clamping shell, and the clamping shell is welded from steel plate. The clamping wheel and the clamping shell are rotatably connected.

[0010] Furthermore, in order to improve the structural strength and reliability of the clamping assembly during operation, the first connecting arm is connected to one side of the clamping shell, and the second connecting arm is connected to the other side of the clamping shell. The first connecting arm and the second connecting arm are respectively fixedly connected to both ends of the connecting shaft to form a U-shaped structure. The clamping shell and the first connecting arm and the second connecting arm are respectively fixedly connected to the ends of the U-shaped structure formed by the two ends of the connecting shaft.

[0011] Furthermore, in order to improve the detection accuracy of the transmission detection component, the present invention provides a logging head clamping and conveying device, wherein the transmission detection component further includes an angle bracket and a driving device, the angle bracket is rotatably connected to the support frame, the pressure roller is rotatably connected to one end of the angle bracket, and the other end of the angle bracket is connected to the driving device, the driving device being able to drive the angle bracket to rotate relative to the support frame.

[0012] Furthermore, in order to further improve the detection accuracy of the transmission detection component, the logging head clamping and conveying device of the present invention also includes a buffer component. One end of the buffer component is connected to the driving device. When the driving device drives the angle bracket to rotate relative to the support frame, the buffer component can stretch the driving device at the end connected to the driving device.

[0013] Furthermore, in order to ensure the reliability and stability of the operation of the driving device, the harvesting head clamping and conveying device of the present invention includes a telescopic cylinder, one end of which is connected to the corner bracket and the other end of which is connected to the buffer assembly.

[0014] Furthermore, in order to improve the reliability of the buffer assembly, the logging head clamping and conveying device of the present invention includes a connecting member, a connecting pipe and a spring. The connecting pipe passes through the connecting member, and the spring is sleeved on the connecting pipe at the end of the connecting member and the connecting pipe away from the connecting member. The end of the connecting pipe away from the spring is connected to a telescopic cylinder.

[0015] Furthermore, in the logging head clamping and conveying device of the present invention, the spring is in a compressed state, and the end of the telescopic cylinder connected to the connecting pipe tends to move towards the connecting member.

[0016] The beneficial effects of this invention are:

[0017] This invention discloses a logging head clamping and conveying device, comprising a frame, a power unit, an auxiliary wheel assembly, a clamping assembly, and a transmission and detection assembly. The device utilizes a support frame to ensure reliable structure for each component. The power unit, auxiliary wheel assembly, and clamping assembly together form a clamping mechanism that can quickly and stably clamp timber. Simultaneously, the transmission and detection assembly reliably detects and provides real-time feedback when the timber is moved in the clamping position, enabling precise clamping of the timber and allowing for efficient logging operations using the logging head. Furthermore, the clamping assembly is optimized to improve its structural strength and reliability, thus ensuring the device's service life and reliable performance. The structure of the transmission and detection assembly is also optimized to improve its stability and reliability. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 5 As shown, the present invention provides a harvesting head clamping and conveying device, including a frame 1, a power component 2, an auxiliary wheel assembly 3, a clamping assembly 4, and a transmission and detection assembly 5. One side of the frame 1 has a V-shaped structure, as shown in the figure. Figure 1 As shown along the side of the device, its structure is visible. The frame 1 is welded from steel plates and is used to support and install the various functional components of the entire device. The power assembly 2 is embedded in one side of the V-shaped structure of the frame 1, at the middle position. Figure 2 As shown, the power assembly 2 is embedded inside the frame 1, and a portion of the power assembly 2 protrudes from the inside of the frame 1. The power assembly 2 includes a protective housing 201 and a drive roller 202. A hydraulic drive assembly is installed inside the protective housing 201 to drive the rotation of the drive roller 202, thereby allowing the device to move the clamped position after clamping the wood. Figure 12 The auxiliary wheel assembly 3 shown includes an adapter plate 301 and an auxiliary wheel 302. The auxiliary wheel 302 is rotatably connected to the adapter plate 301, and the adapter plate 301 is fixedly connected to the frame 1. The auxiliary wheel assembly 3 is embedded in the middle of the inner side of the V-shaped structure of the frame 1, opposite to the side where the power assembly 2 is installed. Figure 2 The diagram shows its relative installation position, as shown in the image. Figure 1 , Figure 2 and Figure 4 The auxiliary roller 302 and the active roller 202 have a V-shaped structure on their axes, which can create a better clamping effect on the wood.

[0033] like Figures 1 to 9 As shown, the clamping assembly 4 includes a connecting shaft 41, a first connecting arm 42, a second connecting arm 44, a connecting swing arm 43, a clamping component 45, and an adjusting connecting rod 46. The connecting shaft 41 is connected to the end of the frame 1 that is V-shaped and away from the power component 2. One end of the second connecting arm 44 is fixedly connected to one end of the connecting shaft 41, and the other end is rotatably connected to the clamping component 45. One end of the first connecting arm 42 is fixedly connected to the other end of the connecting shaft 41, and the other end is rotatably connected to the clamping component 45. The first connecting arm 42 and the second connecting arm 44 are respectively fixedly connected to both ends of the connecting shaft 41 to form a U-shaped structure, so that the first connecting arm 42 and the second connecting arm 44 can rotate synchronously, thereby driving the movement of the clamping assembly 4. The middle part of the connecting swing arm 43 is rotatably connected to the connecting shaft 41. One end of the connecting swing arm 43 is connected to the clamping component 45 through the adjusting connecting rod 46. The end of the connecting swing arm 43 away from the one connected to the adjusting connecting rod 46 is connected to the frame 1. As shown in the figure, the device is also equipped with a transmission detection component 5 for assisting in detecting the displacement of the wood during its movement relative to the device. It includes a support frame 501 and a pressure roller 502. The support frame 501 is fixedly connected to the frame 1, and the pressure roller 502 is connected to the support frame 501. The pressure roller 502 is located in the middle of the inner side of the V-shaped structure of the frame 1, close to the auxiliary wheel assembly 3 and the power assembly 2.

[0034] A hydraulic cylinder is installed between the end of the first connecting arm 42, which is fixedly connected to the connecting shaft 41, and the frame 1 to drive the first connecting arm 42, the connecting shaft 41, and the second connecting arm 44 to rotate relative to the frame 1. The first connecting arm 42, the second connecting arm 44, the connecting swing arm 43, the adjusting connecting rod 46, and the clamping component 45 form a four-bar linkage structure. The hydraulic cylinder drives the first connecting arm 42, the connecting shaft 41, and the second connecting arm 44 to rotate relative to the frame 1, causing the clamping component 4 to move closer to or further away from the auxiliary rotating wheel 302 and the active roller 202. That is, the hydraulic cylinder drives the clamping component 45, the auxiliary rotating wheel 302, and the active roller 202 to clamp the wood. After clamping, the clamping position of the device on the wood can be moved by the drive of the active roller 202. Simultaneously, the transmission detection component 5 can accurately detect the displacement of the wood. When using this device, if... Figure 1 The diagram shows the structure of the clamping component 4 when it is close to the power component 2. In this position, the device can clamp the wood. Figure 4The diagram shows the structure of the clamping component 4 when it is far away from the power component 2. This is the structural state of the device when it is not clamping timber. The logging head clamping and conveying device uses a bracket to support the reliable structure of each component. The power component 2, auxiliary wheel component 3, and clamping component 4 form a clamping mechanism that can quickly and stably clamp timber. At the same time, in conjunction with the transmission detection component 5, it can reliably detect and provide feedback in real time when the timber clamping position is moved, which can accurately achieve the device's clamping of timber, so that the logging head can be used for efficient logging operations.

[0035] Furthermore, in this invention, a logging head clamping and conveying device is provided. To improve the applicability of the clamping component 4 in the device when logging timber of different diameters, thereby increasing the efficiency of timber harvesting operations, the two ends of the adjusting connecting rod 46 are respectively connected to the clamping component 45 and the connecting swing arm 43. The adjusting connecting rod 46 can adjust the distance between the clamping component 45 and the connecting swing arm 43, thereby adjusting the clamping effect of the clamping component 4, the auxiliary wheel component 3, and the power component 2. In other words, by adjusting the distance between the clamping component 45 and the connecting swing arm 43, the structural dimensions of the four-bar linkage structure consisting of the first connecting arm 42, the second connecting arm 44, the connecting swing arm 43, the adjusting connecting rod 46, and the clamping component 45 can be adjusted, thereby adjusting the clamping angle of the clamping component 4 and making the device more adaptable to clamping timber of different sizes.

[0036] like Figures 6 to 9 As shown, further, in this invention, a harvesting head clamping and conveying device, to improve the structural strength of the clamping component 45 and thus ensure that the device can operate stably for a long time, the clamping component 45 includes a clamping wheel 451 and a clamping shell 452. The clamping wheel 451 is sleeved inside the clamping shell 452, which is welded from steel plates. The clamping wheel 451 and the clamping shell 452 are rotatably connected. That is, by setting the clamping shell 452 to protect the clamping wheel 451, the clamping wheel 451 can be effectively protected from damage during harvesting operations, thereby improving the service life of the clamping component 45. Similarly, to improve the structural strength and reliability of the clamping assembly 4 during operation, one end of the first connecting arm 42 is connected to one side of the clamping shell 452, and one end of the second connecting arm 44 is connected to the other side of the clamping shell 452. The first connecting arm 42 and the second connecting arm 44 are respectively fixedly connected to both ends of the connecting shaft 41 to form a U-shaped structure. The clamping shell 452, the first connecting arm 42, and the second connecting arm 44 are respectively fixedly connected to the ends of the U-shaped structure formed by the two ends of the connecting shaft 41. That is, by connecting the clamping shell 452 to one end of the first connecting arm 42, the second connecting arm 44, and the adjusting connecting rod 46 respectively, a good protective effect can be achieved for the clamping component 45.

[0037] Furthermore, in this invention, a harvesting head clamping and conveying device is provided to improve the detection accuracy of the transmission detection component 5, such as... Figure 10 , Figure 11 As shown, the transmission detection assembly 5 further includes an angle bracket 503 and a driving device. The angle bracket 503 is rotatably connected to the support frame 501. The pressure roller 502 is rotatably connected to one end of the angle bracket 503, and the other end of the angle bracket 503 is connected to the driving device. The driving device can drive the angle bracket 503 to rotate relative to the support frame 501. That is, Figure 2 As shown, the driving action of the drive device allows the pressure roller 502 to have a better adaptability space, thereby preventing the pressure roller 502 from failing to make good contact with the wood when clamping wood of different diameters, which would lead to inaccuracy of the transmission detection component 5.

[0038] Furthermore, in order to further improve the detection accuracy of the transmission detection component 5, the logging head clamping and conveying device of the present invention also includes a buffer component. One end of the buffer component is connected to the driving device. When the driving device drives the angle bracket 503 to rotate relative to the support frame 501, the buffer component can stretch the driving device at the end connected to the driving device. By setting the buffer when the driving device drives the angle bracket 503 to rotate relative to the support frame 501, the pressure roller 502 can play a better buffering role when it contacts and squeezes the wood and when the wood moves relative to the device, thereby preventing the problem of the pressure roller 502 being easily damaged when rolling on the wood surface due to unevenness.

[0039] Furthermore, in this invention, a harvesting head clamping and conveying device is provided to ensure the reliability and stability of the drive device's operation, such as... Figure 10 , Figure 11 As shown, the driving device includes a telescopic cylinder 504, one end of which is connected to the corner bracket 503 and the other end to the buffer assembly. Further, to improve the reliability of the buffer assembly, the buffer assembly includes a connector 505, a connecting pipe 506, and a spring 507. The connecting pipe 506 passes through the connector 505, and the spring 507 is sleeved on the connecting pipe 506 at the end of the connector 505 and the connecting pipe 506 furthest from the connector 505. The end of the connecting pipe 506 furthest from the spring 507 is connected to the telescopic cylinder 504. The spring 507 is in a compressed state, and the end of the telescopic cylinder 504 connected to the connecting pipe 506 tends to move closer to the connector 505. Figure 10 and Figure 11As shown, by using the spring 507 in conjunction with the telescopic cylinder 504, the transmission detection component 5 can clamp timber of different sizes in this device, or when the surface of the timber is uneven, the transmission detection component 5 can effectively detect the amount of movement of the timber relative to the clamping position of this device in real time, thereby ensuring the efficient operation of logging.
