Description

Technical Field

[0001] This application relates to the technical field of cutting rods, and in particular to a flexible cutting rod and its tightening and unloading mechanism. Background Technology

[0002] A sampling rod, also known as a sampling rod, is a tool used to collect representative samples from bulk grains, seeds, feed, or other granular materials. It is widely used in agriculture, grain storage, quality inspection, and food processing.

[0003] To collect samples from bulk granular materials, the conventional method is to use a traditional rigid sampling rod. Patent CN105738149A discloses a grain sampling machine with a sampling rod 3-6 meters long. This rod length exceeds the cantilever, resulting in a total equipment height of 7-11 meters. For sites with limited height, this conventional sampling machine cannot be installed and requires improvement. Utility Model Content

[0004] The purpose of this application is to provide a flexible rod and its tightening and unloading mechanism for use in low-height sites.

[0005] The flexible rod and its tightening and unloading mechanism provided in this application adopt the following technical solution: A flexible rod includes a flexible tube and two flexible clips. Each flexible clip has a mounting cavity for engaging with the flexible tube. Each flexible clip has a plurality of engaging portions and a plurality of engaging slots, with each engaging portion and engaging slot engaging in a one-to-one engagement. By adopting the above technical solution, the flexible tube and two flexible clamps are wound around the tightening and unloading machine, resulting in a lower overall equipment height than usual, making it suitable for low-height sites. When the flexible skewer is needed, the tightening and unloading mechanism engages the clamping part with the clamping groove, and the flexible clamps and flexible tube have an interference fit, making the connection of the flexible skewer more stable and ensuring the structural stability of the flexible skewer. This solves the problem that conventional rigid skewer rods cannot be installed in low-height sites due to length and equipment height limitations, allowing for flexible use in more locations.

[0006] Optionally, the flexible clip includes a plurality of connecting blocks, with two adjacent connecting blocks rotatably connected by a connecting shaft, and the snap-fit ​​portion and the snap-fit ​​groove are disposed on the connecting blocks.

[0007] By adopting the above technical solution, two adjacent connecting blocks are connected by a connecting shaft, which allows the flexible clamp to bend and coil into a circle, making the total height of the equipment lower than the conventional height.

[0008] A tightening and unloading mechanism includes a worktable with two turntables rotatably connected at intervals. The turntables are used for winding flexible components. A winding roller is rotatably connected to the worktable for winding the flexible tube. Two transmission components are rotatably connected to the worktable at intervals. A tightening channel is formed between the two transmission components for the flexible tube and flexible components to pass through. A drive assembly is connected to the worktable for driving the two transmission components to rotate in opposite directions.

[0009] By adopting the above technical solution, one end of the two flexible clips and part of the flexible tube are installed in the tightening channel. When the flexible rod is needed, the drive assembly drives the two transmission components to rotate in opposite directions. The two transmission components abut against the two flexible clips respectively and drive the two flexible clips to slide along the direction of the flexible tube. During the movement of the flexible clips, the flexible tube and the flexible clips move synchronously. The snap-fit ​​part of one flexible clip engages with the snap-fit ​​groove of the other flexible clip, thereby realizing the automatic installation of the two flexible clips on the flexible tube, so that the assembled flexible rod can move vertically.

[0010] Optionally, the workbench is connected to two rope take-up devices, each corresponding to a turntable, and the rope of the rope take-up device is connected to the rotation shaft of the turntable.

[0011] By adopting the above technical solution, the flexible clip can be wound around the turntable, and the pull rope of the rope take-up device is connected to the turntable, which can play an auxiliary role in taking in and releasing the turntable, making it convenient to store and release the flexible clip.

[0012] Optionally, the transmission component includes a transmission belt and two rotating rods rotatably connected to the worktable, the transmission belt being sleeved on the two rotating rods, and the drive assembly being used to drive the rotating rods to rotate.

[0013] By adopting the above technical solution, the driving component drives the rotating rod to rotate, the rotating rod drives the transmission belt to rotate, and the transmission belt abuts against the flexible clamp during the rotation process and drives the flexible clamp to move, thereby realizing the automatic installation of the flexible clamp on the flexible tube, so that the assembled flexible rod can move vertically.

[0014] Optionally, each of the rotating rods is provided with a limiting ring groove, which is used to rotate with the conveyor belt.

[0015] By adopting the above technical solution, when the conveyor belt is rotating, the limiting ring groove cooperates with the rotation of the conveyor belt to guide and limit the rotation of the conveyor belt, thereby improving the stability of the conveyor belt rotation and preventing the conveyor belt from detaching from the conveyor belt during rotation.

[0016] Optionally, each of the conveyor belts has a plurality of conveyor blocks connected to its outer surface, and each of the conveyor blocks has a conveyor groove on the side away from the conveyor belt, the conveyor groove being used to cooperate with a flexible card.

[0017] By adopting the above technical solution, the cooperation between the transmission groove and the flexible card increases the contact area between the flexible card and the transmission block, thereby increasing the friction and facilitating the movement of the flexible card.

[0018] Optionally, the drive assembly includes a drive gear rotatably connected to the worktable, two driven gears, and a drive member for driving the drive gear to rotate. The two driven gears are respectively connected to one of the rotating rods of the two transmission members. The drive gear meshes with one of the driven gears, and the two driven gears mesh.

[0019] By adopting the above technical solution, the driving component drives the active gear to rotate, the active gear drives the passive gear meshing with it to rotate, the two passive gears rotate, which in turn drives the corresponding rotating rod to rotate, so that the two conveyor belts rotate. The rotation of the two conveyor belts is connected through the driving component, the active gear and the two passive gears, reducing the driving force and increasing the overall structural coherence.

[0020] Optionally, the workbench is connected to a support block, the support block being provided with support holes for flexible clamps to pass through.

[0021] By adopting the above technical solution, when the flexible tube and flexible clamp pass through the tightening channel, the support hole of the support block can support and guide the assembled flexible rod, so that the flexible rod passes through more stably and improves the stability of the movement of the flexible rod.

[0022] Optionally, the worktable is rotatably connected to a support roller, the support roller corresponds to the tightening channel, and the support roller is provided with a support ring groove for sliding cooperation with the flexible tube.

[0023] By adopting the above technical solution, the inner wall of the support ring groove can support the flexible tube, making the flexible tube pass through the tightening channel more smoothly and improving the effect of installing the flexible clamp on the flexible tube.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The flexible tube and two flexible clamps are wound around the tightening and unloading machine, making the overall height of the equipment lower than the conventional height. When the flexible skewer is needed, the tightening and unloading mechanism engages the clamping part with the clamping groove. The flexible clamps and the flexible tube have an interference fit, making the connection of the flexible skewer more stable and ensuring the structural stability of the flexible skewer. This solves the problem that conventional rigid skewer rods cannot be installed in height-limited sites due to length and equipment height limitations, allowing for flexible use in more locations.

[0025] 2. One end of each of the two flexible clips and part of the flexible tube are installed in the tightening channel. When the flexible rod is needed, the drive assembly drives the two transmission components to rotate in opposite directions. The two transmission components abut against the two flexible clips respectively and drive the two flexible clips to slide along the direction of the flexible tube. During the movement of the flexible clips, the flexible tube and the flexible clips move synchronously. The snap-fit ​​part of one flexible clip engages with the snap-fit ​​groove of the other flexible clip, thereby realizing the automatic installation of the two flexible clips on the flexible tube, so that the assembled flexible rod can move vertically.

A flexible tube 1 is wound around the winding roller 35, reducing the space occupied by the flexible tube 1. A drive motor is fixedly connected to the worktable 3. Pulleys are fixedly connected to the output end of the drive motor and one end of the winding roller 35. Belts are fitted onto the two pulleys. The drive motor drives the winding roller to rotate via the belts and the two pulleys, realizing the winding and unwinding of the flexible tube 1. A controller (not shown in the attached diagram) is externally connected to the drive motor, and the signal output end of the controller is connected to the signal input end of the drive motor. Two turntables 31 are rotatably connected to the worktable 3, spaced apart. Two flexible clips 2 are wound around the turntables 31, reducing the space occupied by the two flexible clips 2. Two rope take-up devices 4 are fixedly connected to the worktable 3, each corresponding to one of the turntables 31. The pull rope of the rope take-up device 4 is fixedly connected to the rotation shaft of the turntable 31. The workbench 3 is rotatably connected to two transmission components 5, which are arranged opposite to each other. A tightening channel 32 is formed between the two transmission components 5. The flexible tube 1 and two flexible clamps 2 pass through the tightening channel 32 to complete the assembly. The transmission component 5 includes a transmission belt 51 and two rotating rods 52 rotatably connected to the workbench 3. The two rotating rods 52 are arranged opposite to each other. The transmission belt 51 is sleeved on the two rotating rods 52. A limiting ring groove 521 is formed on the outer circumference of each rotating rod 52. The transmission belt 51 is rotatably engaged with the limiting ring groove 521. Several transmission blocks 53 are fixedly connected to the outer surface of each transmission belt 51. A transmission groove 531 is formed on the side of each transmission block 53 away from the transmission belt 51. The transmission groove 531 engages with the flexible clamps 2. During the movement of the transmission block 53, the inner wall of the transmission groove 531 abuts against the flexible clamps 2 and drives the flexible clamps 2 to move, thereby realizing the automatic assembly of the flexible clamps 2 onto the flexible tube 1.

[0037] Combination Figure 4 and Figure 5As shown, the workbench 3 is connected to a drive assembly 6. The drive assembly 6 includes two driven gears 61, a drive gear 62 rotatably connected to the workbench 3, and a drive component 63 fixedly connected to the workbench 3. The drive component 63 is a motor. The signal output terminal of the controller is connected to the signal input terminal of the drive component 63. The side of the drive gear 62 closest to the drive component 63 is fixedly connected to the output terminal of the drive component 63. The two driven gears 61 are respectively fixedly connected to one of the rotating rods 52 of the two transmission components 5. The two driven gears 61 mesh, and the drive gear 62 meshes with one of the driven gears 61.

The support block 33 has a support hole 331 through which the flexible tube 1 and two flexible clips 2 pass. A support roller 34 is rotatably connected to the worktable 3. The support roller 34 corresponds to the tightening channel 32. Two transmission components 5 are located between the support roller 34 and the support block 33. A support ring groove 341 is formed on the outer circumferential surface of the support roller 34, and the flexible tube 1 cooperates with the support ring groove 341.

[0039] The implementation principle of a flexible rod in this application embodiment is as follows: One end of each of the two flexible clips 2 and part of the flexible tube 1 are installed in the tightening channel 32. When the flexible rod is needed, the drive motor drives the winding roller 35 to rotate, realizing the feeding of the flexible tube 1. The drive component 63 drives the active gear 62 to rotate, and the two passive gears 61 rotate in opposite directions, that is, the two transmission components 5 rotate in opposite directions. When the two transmission components 5 respectively abut against the two flexible clips 2 and drive the two flexible clips 2 to slide along the length direction of the flexible tube 1, the flexible tube 1 and the flexible clips 2 move synchronously during the movement of the flexible clips 2. The snap-fit ​​part 212 of one flexible clip 2 engages with the snap-fit ​​groove 213 of the other flexible clip 2, thereby realizing the automatic installation of the two flexible clips 2 on the flexible tube 1, so that the assembled flexible rod can move vertically.
