DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1 to 5 In the embodiment of the present invention, a leaf cutting and sampling device for forest pest control includes a cutting component 1, which includes a sample storage barrel 101, a cross bar 102 is fixedly connected to the side wall of the sample storage barrel 101 by bolts, an opening is cut in the middle of the cross bar 102, and a hinged rod 103 is rotatably connected to the inner side wall of the opening, and the pressing frame 201 can be pressed by squeezing the cross bar 102 and the hinged rod 103, and the lever can achieve the purpose of labor saving, and a sample cutting barrel 104 is arranged on the upper side of the sample storage barrel 101, and two connecting barrels 105 are connected and fixed between the sample cutting barrel 104 and the sample storage barrel 101, and a flipping component 2 for driving the sampling knife barrel 203 to flip is installed on the upper side wall of the sample storage barrel 101; The flip assembly 2 includes a pressing frame 201 inserted into the upper side wall of the sample cutting tube 104, and the pressing frame 201 is set to a C-shaped structure with an opening facing downward. The front and rear inner walls of the sample storage tube 101 are slidably connected to two movable plates 206. The front and rear inner walls of the sample storage tube 101 are both opened with sliding grooves. The two movable plates 206 are slidably connected by sliding blocks clamping the sliding grooves, and the sliding blocks are covered with rubber blocks, so as to increase the movement resistance of the two movable plates 206, so that the two movable plates 206 will not automatically move downward due to gravity. The two movable plates 206 are rotatably connected to the same rotating rod 202, and two connecting ropes 207 are fixedly connected between the movable plates 206 and the lower end of the pressing frame 201. The middle part of the rotating rod 202 is fixedly connected to the sampling knife cylinder 203 by welding. The rotating rod 202 is rotatably connected to two left and right pressing frames 201 through a one-way bearing. The gears 204 on the right side, when the pressing frame 201 moves down, the pressing frame 201 pushes the movable plate 206 to move down, and the gears 204 cannot drive the rotating rod 202 to rotate. When the pressing frame 201 rebounds and moves up, the pressing frame 201 pulls the movable plate 206 up through the connecting rope 207. At this time, the gear 204 will drive the rotating rod 202 to rotate under the action of the one-way bearing. The upward movement of the gear 204 driven by the rebound of the pressing frame 201 can drive the rotating rod 202 to rotate exactly 180 degrees, so that the blades at both ends of the sampling knife cylinder 203 can be replaced. The inner wall of the rear side of the sample cutting cylinder 104 is fixedly connected with a toothed plate 205 by bolts. The tooth surface on the toothed plate 205 meshes with the gear 204, so that when the gear 204 moves up and down, it drives the gear 204 to rotate. A transmission component 3 that drives the rotating block 401 to rotate is installed inside the sample storage cylinder 101.

[0023] After pinching the cross bar 102 and the hinged rod 103, the hinged rod 103 will press the pressing frame 201 to move the pressing frame 201 downward. Due to the resistance between the moving plate 206 and the cutting tube 104, the moving plate 206 will not move downward at this time. Until the pressing frame 201 can abut against the moving plate 206, the pressing frame 201 will push the moving plate 206 downward. At this time, the moving plate 206 can drive the rotating rod 202 to move downward, so that the knife head of the sampling knife cylinder 203 can be pressed against the leaf The sheet is pressed and cut, and when the pressing frame 201 moves up and rebounds on the spring 504, the pressing frame 201 pulls the moving plate 206 up through the connecting rope 207, and the moving plate 206 drives the gear 204 to move up through the rotating rod 202. At this time, the gear 204 rotates through the engagement of the tooth plate 205, and the gear 204 drives the rotating rod 202 to rotate through the one-way bearing, so that the sampling knife cylinder 203 completes the flipping, thereby replacing the knife head of the sampling knife cylinder 203.

[0024] It is worth noting that when the pressing frame 201 moves downward, the cleaning wiper 505 can be sleeved on the sampling knife cylinder 203, so the sampling knife cylinder 203 will not deflect a certain angle due to the friction force that may be generated by the one-way bearing, thereby improving the stability of the sampling knife cylinder 203.

[0025] The transmission assembly 3 includes two first gears 301 rotatably connected to the inner walls of the left and right sides of the sample storage cylinder 101, and the inner walls of the left and right sides of the sample cutting cylinder 104 are rotatably connected to the second gears 302. A toothed belt 303 is sleeved between the first gear 301 and the second gear 302, and the toothed belt 303 runs through the connecting cylinder 105. The two second gears 302 are rotatably connected to the opposite side walls and the two ends of the rotating rod 202 with universal joints 304. A telescopic rod 305 is rotatably connected between the two universal joints 304. The two first gears 301 are fixedly connected. There is a fixed rod 306, and a sample storage component 4 is slidably connected to the fixed rod 306. When the pressing frame 201 moves upward, the gear 204 pulls the movable plate 206 upward through the connecting rope 207, and the movable plate 206 also drives the universal joint 304 to rotate through the rotating rod 202, and then the universal joint 304 drives another universal joint 304 to rotate through the telescopic rod 305, and finally drives the universal joint 304 to rotate. The universal joint 304 drives the first gear 301 to rotate through the toothed belt 303, and the first gear 301 drives the sample storage component 4 to rotate through the fixed rod 306.

[0026] The sample storage component 4 includes a rotating block 401 slidably connected to the fixed rod 306. Since the cross-section of the fixed rod 306 is square, the fixed rod 306 can drive the rotating block 401 to rotate when it rotates. A plurality of threaded slots 402 are drilled on the rotating block 401, and sampling tubes 403 are inserted into the plurality of slots 402. A threaded groove 404 matching the distribution trajectory of the slots 402 is drilled on the side wall of the rotating block 401. A slider 405 with a semicircular bottom is fixedly connected to the inner wall of the sample storage tube 101, and the slider 405 is slidably connected to the inside of the threaded groove 404. A magnetic ring cutting block 406 is fixedly connected to the upper end of the sampling tube 403. When in use, the inclined surface of the knife head of the sampling knife cylinder 203 can be offset against the inner ring angle of the magnetic ring cutting block 406, so that the blade can completely fall into the sampling tube 403. A cleaning component 5 is fixedly connected between the pressing frame 201 and the sample cutting tube 104.

[0027] When the fixed rod 306 drives the rotating block 401 to rotate, the slider 405 is slidably connected to the inside of the threaded groove 404, thereby driving the rotating block 401 to rotate and move at the same time. Since the multiple sampling barrels 403 are distributed in a spiral shape, during the rotation and movement of the rotating block 401, each sampling barrel 403 can pass directly under the sampling knife barrel 203, so that each cut leaf sample can be loaded into a different sampling barrel 403 to avoid infection between samples.

[0028] It is worth noting that due to the difference in diameter between the second gear 302 and the first gear 301, the rotation angle of the second gear 302 is greater than the rotation angle of the first gear 301. When the second gear 302 rotates 180 degrees, the first gear 301 can drive the rotating block 401 to rotate, so that the next sampling cylinder 403 corresponds to the bottom of the sampling knife cylinder 203.

[0029] The cleaning assembly 5 includes a fixed cylinder 501 fixedly connected to the upper side wall of the cutting sample cylinder 104, a movable threaded block 502 is slidably connected inside the fixed cylinder 501, a threaded rod 503 is threadedly connected to the movable threaded block 502, and the threaded rod 503 is rotatably connected to the upper inner wall of the pressing frame 201, a spring 504 is fixedly connected between the upper inner wall of the pressing frame 201 and the cutting sample cylinder 104, and a cleaning wiper 505 matching the sampling knife cylinder 203 is fixedly connected to the upper end of the threaded rod 503. In the initial state, when the pressing frame 201 moves downward, First, the threaded rod 503 will drive the movable threaded block 502 to move downward. When the movable threaded block 502 moves down to the bottom of the fixed cylinder 501, the cleaning wiper block 505 can completely wrap the cutting head of the sampling knife cylinder 203. As the pressing frame 201 continues to move downward, the movable threaded block 502 is restricted by the fixed cylinder 501 and cannot move downward. Therefore, the threaded rod 503 will rotate under the thread pressure of the movable threaded block 502, so that the rotation of the threaded rod 503 can effectively clean the cutting heads at both ends of the sampling knife cylinder 203.

[0030] Example 2: Please refer to Figures 5 to 8 Based on Example 1, the rear side wall of the sample storage tube 101 is fixedly connected to a tube removal assembly 6, and the tube removal assembly 6 includes a sealing sheet 601 slidably connected to the rear side wall of the sample storage tube 101, and a through hole 602 is drilled on the rear side wall of the sample storage tube 101. The rear side wall of the sample storage tube 101 is fixedly connected to a fixed plate 603, and a rotating plate 604 is rotatably connected to the fixed plate 603. The rotating plate 604 is fixedly connected to a magnetic block 605 that is magnetically attracted to the magnetic ring cutting block 406. The sample storage tube 101 The rear side wall is fixedly connected with a limit plate 606 which abuts against the rotating plate 604, and the side wall of the sample storage tube 101 is rotatably connected with a knob 607, and the knob 607 is fixedly connected to the first gear 301. When it is necessary to take out the sampling tube 403, the staff only needs to slide the sealing sheet 601 to open the through hole 602, and use the magnetic force of the magnetic block 605 and the magnetic ring cutting block 406 to automatically bring out the sampling tube 403. At this time, the staff can directly take out the sampling tube 403.

[0031] It is worth noting that when rotating the knob 607, it is necessary to rotate in the direction opposite to the rotation direction of the rotating block 401 when sampling, so as to drive the first gear 301 to rotate in the opposite direction. When the first gear 301 rotates in the opposite direction, the second gear 302 can be driven to rotate through the toothed belt 303. Since a one-way bearing is installed between the gear 204 and the rotating rod 202, when the second gear 302 rotates in the opposite direction, it will not affect the gear 204, nor will it drive the moving plate 206 to move. It can only drive the sampling knife cylinder 203 to rotate. Therefore, when using it, the staff needs to pay attention to whether the slot 402 corresponds to the through hole 602. When the slot 402 corresponds to the through hole 602, the sampling knife cylinder 203 is in a vertical state.

[0032] The working principle of the present invention is: When the present invention is in use, first, the staff puts the collected leaves in the gap between the sample storage tube 101 and the sample cutting tube 104, and then the staff squeezes the cross bar 102 and the hinged rod 103 so that the hinged rod 103 presses the pressing frame 201 to move downward. When the pressing frame 201 and the movable plate 206 are against each other, the pressing frame 201 will push the movable plate 206 to move downward. At this time, the movable plate 206 can drive the rotating rod 202 to move downward, so that the blade head of the sampling knife cylinder 203 can press and cut the leaves, and the inclined surface of the blade head of the sampling knife cylinder 203 can be against the inner ring angle of the magnetic ring cutting block 406, so that the leaves can completely fall into the sampling tube 403. At the same time, when the pressing frame 201 moves downward, the threaded rod 503 drives the movable threaded block 502 to move downward. When the movable threaded block 502 moves downward to the bottom of the fixed cylinder 501, the cleaning wiper block 505 can completely wrap the cutting head of the sampling knife cylinder 203. As the pressing frame 201 continues to move downward, the movable threaded block 502 is restricted by the fixed cylinder 501 and cannot move downward. Therefore, the threaded rod 503 rotates under the thread pressure of the movable threaded block 502, so that the threaded rod 503 rotates to effectively clean the cutting heads at both ends of the sampling knife cylinder 203. Then the staff releases the cross bar 102 and the hinge rod 103, and the pressing frame 201 rebounds under the action of the spring 504. The pressing frame 201 pulls the moving plate 206 upward through the connecting rope 207, and the moving plate 206 drives the gear 204 upward through the rotating rod 202. At this time, the gear 204 rotates through the meshing of the tooth plate 205, and the gear 204 drives the rotating rod 202 to rotate through the one-way bearing, so that the sampling knife cylinder 203 is turned over, thereby replacing the knife head of the sampling knife cylinder 203; At the same time, during the upward movement of the movable plate 206, the movable plate 206 will also drive the universal joint 304 to rotate through the rotating rod 202, and then the universal joint 304 will drive another universal joint 304 to rotate through the telescopic rod 305, and finally drive the universal joint 304 to rotate, and the universal joint 304 will drive the first gear 301 to rotate through the toothed belt 303, and the first gear 301 will drive the rotating block 401 to rotate through the fixed rod 306, and the sliding block 405 is slidably connected to the inside of the thread groove 404, so that the rotating block 401 can be driven to rotate and move at the same time. Since the multiple sampling barrels 403 are distributed in a spiral shape, each sampling barrel 403 can pass directly under the sampling knife barrel 203 during the rotation and movement of the rotating block 401, thereby realizing the replacement of multiple sampling barrels 403; When the sample needs to be taken out, the staff only needs to drive the rotating block 401 to rotate in the opposite direction through the knob 607. When the slot 402 corresponds to the through hole 602, the sampling tube 403 can be automatically taken out by utilizing the magnetic force of the magnetic block 605 and the magnetic ring cutting block 406. At this time, the staff can directly take out the sampling tube 403.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
