Description

Technical Field

[0001] This utility model relates to the field of wood chipper technology, and in particular to a wood chipper with a tensioning device. Background Technology

[0002] A wood chipper is a machine used to crush wood materials such as timber, branches, and leaves into small chips or granules. It is commonly used in industries such as wood processing, landscaping, and waste recycling. Wood chippers can efficiently cut large pieces of timber or branches into uniformly sized chips, facilitating transportation, storage, or further processing.

[0003] In the prior art, traditional wood chippers are generally driven by an external motor, and the external motor is connected to the drive shaft on the wood chipper by a belt and pulley. However, after long-term use, the belt will stretch and loosen, which will cause the belt to slip or even fall off, thus affecting the normal use of the wood chipper. Therefore, this application proposes a wood chipper with a tensioning device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing wood chippers, which are generally driven by an external motor and connected to the drive shaft of the wood chipper via a belt and pulley. However, the belt can stretch and loosen after prolonged use, leading to slippage or even detachment, thus affecting the normal operation of the wood chipper. Therefore, this invention proposes a wood chipper with a tensioning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wood chipper with a tensioning device includes a worktable, the tensioning device further comprising:

[0007] The main body of the wood chipper is fixedly installed on the top of the workbench. A drive shaft is installed inside the main body of the wood chipper, and the two ends of the drive shaft extend to the front and rear sides of the main body of the wood chipper, respectively.

[0008] Mounting plate, which is slidably connected to the top of the workbench;

[0009] The motor is fixedly mounted on the top of the mounting plate;

[0010] The transmission wheel is provided in two parts, which are respectively fixedly installed on the front end of the transmission shaft and the output shaft of the motor, and the same transmission belt is fitted on the two transmission wheels;

[0011] The tensioning assembly includes a rectangular tube, a rectangular rod, a first spring, and a tensioning wheel. The bottom end of the rectangular tube is fixedly installed on the front side of the wood chipper body. The bottom end of the rectangular rod extends into the interior of the rectangular tube and is slidably connected to the inner wall of the rectangular tube. The bottom end of the first spring is fixedly installed on the bottom inner wall of the rectangular tube. The top end of the first spring is fixedly installed on the bottom end of the rectangular rod. The tensioning wheel is rotatably connected to the top end of the rectangular rod and makes rolling contact with the bottom of the transmission belt.

[0012] An adjustment component is disposed on the top of the workbench and cooperates with the mounting plate.

[0013] As a preferred embodiment of this utility model, the top of the workbench has two sliding grooves, and the bottom of the mounting plate has two sliders fixedly installed, with the sliders slidably connected in the corresponding sliding grooves.

[0014] In a preferred embodiment of this utility model, the adjustment assembly includes a fixed plate, a lead screw, a nut, a handle, and a limiting plate. The bottom end of the fixed plate is fixedly installed on the left side of the mounting plate, the right end of the lead screw is rotatably connected to the left side of the fixed plate, the nut is threaded onto the lead screw, and the bottom end of the nut is fixedly installed on the top of the workbench. The handle is fixedly installed on the left end of the lead screw, and the limiting plate is fixedly installed on the handle. The limiting plate has multiple limiting grooves evenly spaced in a ring. A limiting component is provided on the top of the workbench, and the limiting component cooperates with the corresponding limiting groove.

[0015] In a preferred embodiment of this utility model, a rotating seat is installed on the left side of the fixed plate, and the right end of the lead screw is rotatably connected to the rotating seat.

[0016] As a preferred embodiment of this utility model, the limiting assembly includes two sliding shafts, two sliding rings, and a limiting rod. The bottom ends of the two sliding shafts are fixedly installed on the top of the worktable, and the sliding rings are slidably sleeved on the corresponding sliding shafts. The left and right ends of the limiting rod are respectively fixedly connected to the sides of the two sliding rings that are close to each other, and the top end of the limiting rod is engaged with the corresponding limiting groove.

[0017] In a preferred embodiment of this utility model, a second spring is sleeved on the sliding shaft, with the bottom end of the second spring fixedly installed on the top of the worktable and the top end of the second spring fixedly installed on the bottom of the corresponding sliding ring. Beneficial effects

[0018] 1. By sliding and limiting the rectangular tube and the rectangular rod, and by using the first spring to provide elastic support between the rectangular tube and the rectangular rod, the tensioning wheel can be driven to apply pressure to the transmission belt. This can achieve tension protection of the transmission belt and prevent it from loosening and slipping after long-term use.

[0019] 2. By rotating the lead screw and engaging the threaded connection between the lead screw and the nut, the fixed plate and the motor can be moved laterally. When the motor moves to the right, the tension on the transmission belt can be released, making it easier to install and remove the transmission belt. When the motor moves to the left, after the transmission belt is installed, the position of the motor can be adjusted so that the two transmission wheels are far apart, thus tightening the transmission belt and ensuring that it will not come loose. In this way, even if the tensioning component fails, the transmission belt can be tightened by the motor driving the transmission wheels, thus ensuring the transmission tightness of the transmission belt.

[0020] 3. By locking the limit rod with the limit groove on the limit plate, the rotation limit of the handle and the lead screw can be controlled, which can prevent the vibration generated by the wood chipper body and motor from causing the lead screw to rotate, and ensure the tightness of the transmission belt. Then, when the limit rod disengages from the locking limit between the limit rod and the corresponding limit groove, the rotation limit of the handle can be released, which can facilitate the personnel to rotate the handle and the lead screw, and facilitate the personnel to adjust the lateral position of the motor.

[0021] This utility model achieves efficient tensioning of the transmission belt between the motor and the wood chipper body through a simple structure. In addition, the movement of the motor can drive the transmission wheel to tighten the transmission belt, thereby ensuring the transmission tightness of the transmission belt. It also facilitates the disassembly and maintenance of the transmission belt, making it highly practical. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0028] Reference Figures 1-4 A wood chipper with a tensioning device includes a worktable 1, the tensioning device further comprising:

[0029] Wood chipper body 2, the wood chipper body 2 is fixedly installed on the top of the workbench 1, and a drive shaft 3 is installed inside the wood chipper body 2. The two ends of the drive shaft 3 extend to the front and rear sides of the wood chipper body 2 respectively.

[0030] Mounting plate 4 is slidably connected to the top of workbench 1;

[0031] Motor 5 is fixedly mounted on the top of mounting plate 4;

[0032] The transmission wheel 6 is provided in two parts. The two transmission wheels 6 are respectively fixedly installed on the front end of the transmission shaft 3 and the output shaft of the motor 5. The same transmission belt 7 is sleeved on the two transmission wheels 6.

[0033] The tensioning assembly includes a rectangular tube 8, a rectangular rod 9, a first spring 10, and a tensioning wheel 11. The bottom end of the rectangular tube 8 is fixedly installed on the front side of the wood chipper body 2. The bottom end of the rectangular rod 9 extends into the interior of the rectangular tube 8 and is slidably connected to the inner wall of the rectangular tube 8. The bottom end of the first spring 10 is fixedly installed on the bottom inner wall of the rectangular tube 8. The top end of the first spring 10 is fixedly installed on the bottom end of the rectangular rod 9. The tensioning wheel 11 is rotatably connected to the top end of the rectangular rod 9 and makes rolling contact with the bottom of the transmission belt 7.

[0034] An adjustment component is located on the top of the workbench 1 and is designed to work in conjunction with the mounting plate 4.

[0035] With the above structure, the sliding limit between the rectangular tube 8 and the rectangular rod 9, and the elastic support between the rectangular tube 8 and the rectangular rod 9 by the first spring 10, can drive the tensioning wheel 11 to apply pressure to the transmission belt 7. At this time, the tensioning protection of the transmission belt 7 can be achieved, and the transmission belt 7 can be prevented from loosening and slipping after long-term use.

[0036] As a preferred embodiment of this utility model, the top of the workbench 1 has two sliding grooves 13, and the bottom of the mounting plate 4 is fixedly installed with two sliders 12. The sliders 12 are slidably connected in the corresponding sliding grooves 13. Through the sliding limit cooperation between the sliders 12 and the sliding grooves 13, the mounting plate 4 can be stably slidably limited and slidably supported.

[0037] In a preferred embodiment of this utility model, the adjustment assembly includes a fixed plate 14, a lead screw 16, a nut 17, a handle 18, and a limiting plate 19. The bottom end of the fixed plate 14 is fixedly installed on the left side of the mounting plate 4. The right end of the lead screw 16 is rotatably connected to the left side of the fixed plate 14. The nut 17 is threaded onto the lead screw 16, and its bottom end is fixedly installed on the top of the workbench 1. The handle 18 is fixedly installed on the left end of the lead screw 16. The limiting plate 19 is fixedly installed on the handle 18. Multiple limiting grooves 20 are evenly spaced in a ring on the limiting plate 19. A limiting component is provided on the top of the workbench 1, and the limiting component corresponds to the limiting groove 20. In conjunction with the screw 16, the screw 16 and the nut 17 are connected by a thread, which can drive the fixed plate 14 and the motor 5 to move laterally. When the motor 5 moves to the right, the tension on the transmission belt 7 can be released, making it easier to install and remove the transmission belt 7. When the motor 5 moves to the left, after the transmission belt 7 is installed, the position of the motor 5 can be adjusted so that the two transmission wheels 6 are far apart, which can tighten the transmission belt 7 and ensure that the transmission belt 7 will not come loose. In this way, if the tensioning component fails, the motor 5 can drive the transmission wheels 6 to move and tighten the transmission belt 7, thus ensuring the transmission tightness of the transmission belt 7.

[0038] As a preferred embodiment of this utility model, a rotating seat 15 is installed on the left side of the fixed plate 14, and the right end of the lead screw 16 is rotatably connected to the rotating seat 15. By setting the rotating seat 15, it is convenient to connect and transmit power between the lead screw 16 and the fixed plate 14.

[0039] As a preferred embodiment of this utility model, the limiting assembly includes two sliding shafts 21, two sliding rings 22, and a limiting rod 23. The bottom ends of the two sliding shafts 21 are fixedly installed on the top of the workbench 1. The sliding rings 22 are slidably sleeved on the corresponding sliding shafts 21. The left and right ends of the limiting rod 23 are respectively fixedly connected to the sides of the two sliding rings 22 that are close to each other. The top end of the limiting rod 23 is engaged with the corresponding limiting groove 20. Through the engagement and limiting between the limiting rod 23 and the limiting groove 20 opened on the limiting plate 19, the handle 18 and the lead screw 16 can be rotated and limited. This can prevent the vibration generated during the operation of the wood chipper body 2 and the motor 5 from causing the lead screw 16 to rotate, thus ensuring the tightness of the transmission belt 7. Then, when the limiting rod 23 disengages from the engagement and limiting between it and the corresponding limiting groove 20, the rotation limitation on the handle 18 can be released, making it convenient for personnel to rotate the handle 18 and the lead screw 16, and making it convenient for personnel to adjust the lateral position of the motor 5.

[0040] As a preferred embodiment of this utility model, a second spring 24 is sleeved on the slide shaft 21. The bottom end of the second spring 24 is fixedly installed on the top of the worktable 1, and the top end of the second spring 24 is fixedly installed on the bottom of the corresponding slide ring 22. By setting the second spring 24, the slide ring 22 and the limiting rod 23 can be driven to move upward and reset.

[0041] It should be noted that the specific model of wood chipper body 2 and motor 5 used can be selected by those skilled in the art. Furthermore, the wood chipper body 2 and motor 5 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0042] The working principle of this utility model is as follows: In use, firstly, the wood chipper body 2 and motor 5 are connected to an external power source. Then, through the sliding limit cooperation between the rectangular tube 8 and the rectangular rod 9, and the elastic support between the rectangular tube 8 and the rectangular rod 9 provided by the first spring 10, the tensioning wheel 11 can be driven to apply pressure to the transmission belt 7. This achieves tension protection for the transmission belt 7, preventing it from loosening and slipping after prolonged use. Additionally, by rotating the lead screw 16 and through the threaded connection between the lead screw 16 and the nut 17, the fixing plate 14 and motor 5 can be moved laterally. When the motor 5 moves to the right, the tension on the transmission belt 7 can be released, facilitating the installation and removal of the transmission belt 7. When the motor 5 moves to the left, after the transmission belt 7 is installed, the position of the motor 5 can be adjusted to allow the two transmission belts to move laterally. With wheel 6 moving away, the transmission belt 7 can be tightened, ensuring that the transmission belt 7 will not loosen. In this way, even if the tensioning component fails, the transmission wheel 6 driven by motor 5 can still tighten the transmission belt 7, thus ensuring the transmission tightness of the transmission belt 7. The locking and limiting between the limiting rod 23 and the limiting groove 20 on the limiting plate 19 can limit the rotation of the handle 18 and the lead screw 16, preventing the vibration generated by the wood chipper body 2 and motor 5 from causing the lead screw 16 to rotate, thus ensuring the tightness of the transmission belt 7. Then, when the limiting rod 23 disengages from the locking and limiting between it and the corresponding limiting groove 20, the rotation limit of the handle 18 can be released, allowing personnel to easily rotate the handle 18 and the lead screw 16, and making it easy for personnel to adjust the lateral position of motor 5.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
