[0022] A method for using a pesticide detection device for quantitative sample detection comprises the following steps:

[0023] S1. When in use, insert the reagent tube into the support cylinder at the position of the material box bracket, and then start the transmission motor to rotate the turntable, so that the concave disk and the movable pin on the top of the turntable periodically cooperate with the cross-shaped plate. When the movable pin rotates to the inner position of the movable groove on the surface of the cross-shaped plate, the movable pin rotates the cross-shaped plate ninety degrees, so that the cross-shaped plate rotates the eight support cylinders on the adjustment disk ninety degrees, and the positions of the two support cylinders at the bottom of the material box bracket and the medicine adder are switched;

[0024] S2. When the adjusting disk rotates along the circumference with the wedge block, the wedge block presses against the T-shaped pressure rod position at the lower position of the material box bracket, so that the T-shaped pressure rod is pressed and rises, and then the T-shaped pressure rod rises with the lower part of the two spring rods. During the sliding process between the horizontal pin on the surface of the spring rod and the waist-shaped groove on the pull block, the pull block moves the fixedly connected baffle toward the outside of the L-shaped discharge barrel, so that the fruit and vegetable debris inside the L-shaped discharge barrel falls into the corresponding reagent tube. After the wedge block passes over the position of the T-shaped pressure rod, the T-shaped pressure rod moves down and resets. During the sliding process between the horizontal pin and the waist-shaped groove, the pull block resets and moves with the baffle, so that the baffle seals the L-shaped discharge barrel position again, and automatic quantitative feeding is performed;

[0025] S3. After the adjusting disk rotates 90 degrees with the loaded support tube and reagent tube again, the support tube and reagent tube rotate to the bottom position of the reagent adder, and the reagent adder adds the detection reagent into the reagent tube. Then the adjusting disk continues to rotate 90 degrees with the support tube and reagent tube with the added reagent. At this time, the support tube moves to the position of the arc-shaped rack. In the process of meshing between the circular gear at the lower part of the support tube and the arc-shaped rack, the support tube and the reagent tube with the added reagent rotate synchronously inside the adjusting disk to oscillate. At the same time, the vertical rod at the top of the turntable engages the transmission half gear with the synchronous gear in stages, so that the synchronous gear rotating in stages meshes with the synchronous rack and moves along the arc-shaped rack along the arc groove track. Under the action of the reset spring, the arc-shaped rack moves back and forth, and the support tube and reagent tube with the added reagent rotate back and forth to oscillate.

[0026] S4. Finally, when the adjusting disk rotates to the side wall position of the adjusting bracket with the vibrated supporting cylinder and reagent tube, the cam will periodically press the adjusting rod to move toward the adjusting bracket during the rotation of the vertical rod with the cam. During the process of the cam pressing the adjusting rod, the adjusting disk is in a stopped rotating state. At this time, the adjusting rod slides with the inclined groove on the U-shaped adjusting plate and the adjusting pin at the bottom of the adjusting rack, so that the adjusting rack rises to the limit position. During this process, the adjusting rack meshes with the gear rod on the upper part of the adjusting bracket, so that the gear rod flips the swing plate, and the flipped swing plate drives the hinged pull plate to slide vertically along the inside of the U-shaped block. The swing plate will simultaneously move the U-shaped block and the moving block to the left inside the moving groove, so that the pull plate will move the clamp on the transfer plate to the upper part of the supporting tube on the right side of the adjusting disk to clamp the reagent tube. After the cam that continues to rotate releases the pressure on the adjusting rod, the adjusting rod and the U-shaped adjusting plate will reset and move under the action of the return spring, so that the adjusting rack moves down and resets. After the adjusting rack moves down to the limit position, the gear rod will reverse 180 degrees with the swing plate, so that the swing plate will slide upward with the pull plate inside the U-shaped block, and at the same time move the clamped reagent tube to the right side of the moving groove, and transfer the vibrated reagent tube to the inside of the placement tube.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, through the coordinated use of components such as the adjustment disk, the transmission mechanism and the vibration transfer mechanism, the adjustment disk is staged to rotate ninety degrees under the action of the transmission mechanism to switch the position of the support tube on the top of the adjustment disk. After the adjustment disk stops rotating, the transmission mechanism that continues to run drives the vibration transfer mechanism to automatically vibrate the support tube and the reagent tube after the addition of the reagent, thereby avoiding the need to start the vibration mechanism alone to complete the vibration operation of the reagent tube, thereby improving ease of use.

[0029] In the present invention, through the coordinated use of components such as the adjustment disk, the transmission mechanism and the vibration transfer mechanism, when the adjustment disk stops rotating and adjusting, the vibration transfer mechanism cooperates with the transmission mechanism to automatically transfer the reagent tube after vibration on the right side of the adjustment disk to the inside of the placement tube. This operation is automatically achieved through the operation of the transmission mechanism, avoiding separate operation and improving the convenience of equipment operation.

[0042] An L-shaped transfer groove 10 matching with the adjustment bracket 4 is provided on the right side of the top of the detection bracket 1, and a placement tube 11 is movably connected inside the L-shaped transfer groove 10. It should be noted that: two placement tubes 11 are set as a group, and a movable seat is fixedly connected between the two placement tubes 11. The two placement tubes 11 correspond to the two support tubes 801 on the right side of the top of the adjustment disk 3 one by one, and the adjustment bracket 4 is set in the middle position between the two placement tubes 11 and the corresponding two support tubes 801, and the vibration transfer mechanism 8 on the adjustment bracket 4 transfers the two reagent tubes on the right side of the adjustment disk 3 to the inside of the corresponding placement tubes 11.

[0043] The transmission mechanism 6 includes a transmission groove 601, which is opened inside the detection bracket 1. The left side of the bottom surface of the transmission groove 601 is rotatably connected to a support rod 602. The top of the support rod 602 passes through the transmission groove 601 and is fixedly connected to the bottom of the adjustment disk 3. The lower part of the support rod 602 is fixedly sleeved with a cross-shaped plate 603, and the surface of the cross-shaped plate 603 is provided with four movable grooves 604 equidistantly along the circumference.

[0044] The inner bottom surface of the transmission groove 601 is fixedly connected with a transmission motor 605, the rotating end of the transmission motor 605 is fixedly connected with a turntable 606, the top of the turntable 606 is fixedly connected with a concave disk 607, the turntable 606 is arranged at the bottom position of the cross-shaped plate 603, the side wall of the concave disk 607 overlaps the side wall of the cross-shaped plate 603, the top of the turntable 606 is fixedly connected with a movable pin 608 that matches the movable groove 604, and the bottom of the vertical rod 7 extends to the interior of the transmission groove 601 and is fixedly connected to the top of the concave disk 607. It should be noted that: a recessed groove is provided on the inner bottom surface of the transmission groove 601, and the transmission motor 605 is fixedly connected inside the recessed groove; the four sides of the cross-shaped plate 603 are all arranged as arc-shaped surfaces matching with the concave disk 607, and when the movable pin 608 on the turntable 606 leaves the position of the movable groove 604 of the cross-shaped plate 603, the side wall of the concave disk 607 cooperates with the arc-shaped surface of the side wall of the cross-shaped plate 603, which can limit the rotation of the cross-shaped plate 603 and avoid affecting the use effect.

[0045] In this embodiment, Figures 1 to 8 As shown, the vibration transfer mechanism 8 includes a support cylinder 801, and the support cylinders 801 are set to eight, and the eight support cylinders 801 are equidistantly rotated along the circumference and connected to the top of the adjustment disk 3, and the lower part of the support cylinder 801 penetrates the adjustment disk 3 and is fixedly sleeved with a circular gear 802. It should be noted that: the middle part of the support cylinder 801 is fixedly sleeved with a support bearing, and the outer ring of the support bearing is fixedly connected to the inner wall of the adjustment disk 3, so that the support cylinder 801 can rotate on the adjustment disk 3 with the reagent tube to vibrate the medicine inside the reagent tube.

[0046] An arc-shaped groove 803 is provided on the front side of the top of the detection bracket 1, and an arc-shaped rack 804 is slidably connected inside the arc-shaped groove 803. The side wall of the arc-shaped rack 804 is meshed with the side wall of the corresponding circular gear 802. The right end of the arc-shaped rack 804 is fixedly connected with a synchronous rack 805. A transmission half gear 806 is fixedly sleeved on the upper part of the vertical rod 7. The top of the detection bracket 1 is rotatably connected with a synchronous gear 807, and the synchronous gear 807 is arranged between the synchronous rack 805 and the transmission gear. It should be noted that: when the turntable 606 and the concave disk 607 rotate with the vertical rod 7, the transmission half gear 806 on the vertical rod 7 is periodically meshed with the synchronous gear 807 for transmission, so that the synchronous gear 807 moves along the trajectory of the arc groove 803 with the arc rack 804. At this time, the inner circle position of the arc rack 804 is meshed with the circular gear 802 at the lower position of the two support cylinders 801 at the front end of the adjustment disk 3, so that the support cylinder 801 rotates with the internal reagent tube in stages to achieve the oscillation effect; and in the process of the half gear meshing with the synchronous gear 807, the movable pin 608 on the turntable 606 is no longer in the position of the movable groove 604 on the cross plate 603, so that the arc rack 804 meshes with the corresponding circular gear 802 only after the turntable 606 stops rotating.

[0047] The top of the vertical rod 7 is fixedly connected with a cam 808, the top of the detection bracket 1 is slidably connected with an adjustment rod 809 that matches the adjustment bracket 4, the front end of the adjustment rod 809 overlaps the side wall of the cam 808, and the rear end of the adjustment rod 809 is fixedly connected with a U-shaped adjustment plate 810, and both sides of the U-shaped adjustment plate 810 are provided with oblique grooves 811. It should be noted that: when the turntable 606 rotates with the concave plate 607 and the vertical rod 7, when the convex position of the cam 808 on the upper part of the vertical rod 7 contacts the end of the adjustment rod 809, the movable pin 608 on the turntable 606 is no longer in the position of the movable groove 604 on the cross-shaped plate 603, ensuring that the vibration transfer mechanism 8 transfers the reagent tubes in the two support cylinders 801 on the right side of the top of the turntable 606 after the turntable 606 stops rotating.

[0048] The rear side of the adjustment bracket 4 is vertically slidably connected with an adjustment rack 812, the lower part of the adjustment rack 812 is movably inserted in the middle position of the U-shaped adjustment plate 810, the lower part of the adjustment rack 812 is symmetrically fixedly connected with an adjustment pin 813, the two adjustment pins 813 are respectively slidably connected to the inside of the two inclined grooves 811, and the upper part of the adjustment bracket 4 is rotatably connected with a gear rod 814, and the side wall of the gear rod 814 is engaged with the side wall of the adjustment rack 812. It should be noted that: a sliding block is fixedly connected to the rear side of the adjustment bracket 4, and the adjustment rack 812 is vertically slidably connected to the inside of the sliding block. A restoring spring is movably connected between the bottom of the sliding block and the lower part of the adjustment rack 812. When the raised position of the cam 808 is released from contact with the adjustment rod 809, the restoring spring can move the adjustment rack 812 downward and reset; when the end of the adjustment rod 809 is compressed, it moves with the U-shaped adjustment plate 810. At this time, the inclined groove 811 on the U-shaped adjustment plate 810 cooperates with the adjustment pin 813 at the bottom of the adjustment rack 812 to slide, and the adjustment rack 812 rises and meshes with the gear rod 814, so that the gear rod 814 swings with the swing plate 815 in the direction of the adjustment disk 3.

[0049] The front end of the gear rod 814 passes through the adjusting bracket 4 and is fixedly connected to a swing plate 815. The end of the swing plate 815 away from the gear rod 814 is rotatably connected to a pull plate 816. Vertical grooves 817 are provided on both sides of the pull plate 816. A movable groove 818 is provided on the upper part of the front side of the adjusting bracket 4. A movable block 819 is slidably connected inside the movable groove 818. A U-shaped block 820 is fixedly connected to the front end of the movable block 819. The U-shaped block 820 is slidably connected between the two sides of the pull plate 816. It should be noted that: when the adjusting rack 812 moves upward to the extreme position, the gear rod 814 can swing the swing plate 815 to the horizontal position in the direction of the adjusting disk 3; conversely, when the adjusting rack 812 moves downward to the extreme position, the gear rod 814 rotates the swing plate 815 in the opposite direction by one hundred and eighty degrees; when the swing plate 815 swings in the direction of the adjusting disk 3, the swing plate 815 pulls the movably connected pull plate 816 to slide vertically inside the U-shaped block 820, and at the same time, the U-shaped block 820 translates toward the position of the adjusting disk 3 in the moving groove 818 along with the moving block 819.

[0050] The bottom of the pull plate 816 is fixedly connected with a transfer plate 821, and the top of the transfer plate 821 is symmetrically fixedly connected with a clamp 822 that matches the support tube 801. It should be noted that: when the transfer plate 821 moves to the position above the adjustment disk 3 along with the pull plate 816, the clamp 822 clamps the adjacent reagent tubes, and then the pull plate 816 and the transfer plate 821 move in the reverse direction, so that the reagent tube is moved out of the support tube 801 and moves to the position of the placement tube 11, thereby automatically moving the vibrated reagent tube out of the adjustment disk 3; the clamp here is a prior art and will not be described in detail.

[0051] In this embodiment, Figures 1 to 8 As shown, a pad is symmetrically fixedly connected to the top of the detection bracket 1, an arc-shaped guide rod is connected between the two pads, a guide block is slidably connected to the surface of the arc-shaped guide rod, one end of the guide block is fixedly connected to the side wall of the arc-shaped rack 804, and a reset spring is movably connected between the left side of the guide block and the surface of the adjacent pad.

[0052] The bottom of the arc rack 804 is symmetrically fixed with a pin shaft, and the lower part of the pin shaft is slidably connected to the inside of the arc slot 803. It should be noted that the stability of the arc rack 804 during the movement inside the arc slot 803 is improved by setting the arc guide rod and cooperating with the pin shaft.

[0055] In this embodiment, Figures 1 to 8 As shown, the inner bottom surface of the support tube 801 is fixedly connected with an anti-skid rubber pad, and the top of the support tube 801 is provided with a conical chamfer. It should be noted that the diameter of the support tube 801 is set to 1.5 times the diameter of the reagent tube, and the inside of the support tube 801 is fixedly connected with a conical rubber block, and with the cooperation of the anti-skid rubber pad, the reagent tube is effectively confined inside the support tube 801. Here, the anti-skid rubber pad and the conical rubber block are both based on the existing technology and will not be described in detail.

[0056] In this embodiment, Figures 1 to 8 As shown, the quantitative feeding mechanism 9 includes an L-shaped unloading barrel 901, and the L-shaped unloading barrel 901 is set to two. The two L-shaped unloading barrels 901 are symmetrically fixedly connected to the lower part of the material box bracket 5. The inside of the L-shaped unloading barrel 901 is slidably connected with a baffle 902. The rear end of the baffle 902 passes through the L-shaped unloading barrel 901 and is symmetrically fixedly connected with a pull block 903. The side wall of the pull block 903 is provided with a waist-shaped groove 904. It should be noted that: the two L-shaped unloading barrels 901 correspond one-to-one with the two supporting barrels 801 on the rear side of the top plate of the adjusting disk 3, so that the fruit and vegetable debris inside the L-shaped unloading barrel 901 can accurately fall into the corresponding reagent tube; the side walls of the lower part of the L-shaped unloading barrel 901 are symmetrically fixedly connected with cross bars, and the two pull blocks 903 are respectively slidably connected to the surfaces of the two cross bars. The cross bar setting ensures the stability of the pull blocks 903 and the baffle 902 during the movement, and the baffle 902 is located at one end of the inner wall of the L-shaped unloading barrel 901 and is set to a cone, which is convenient for sealing the interior of the L-shaped unloading barrel 901.

[0057] An electric telescopic rod 905 is fixedly connected to the bottom of the L-shaped discharge barrel 901 , and a transverse pin 906 is symmetrically fixedly connected to the movable end of the electric telescopic rod 905 . The two transverse pins 906 are slidably connected to the inside of the two waist-shaped grooves 904 .

[0058] In this embodiment, Figures 1 to 8 As shown, a method for using a pesticide detection device for quantitative detection of samples includes the following steps:

[0059] S1. When in use, insert the reagent tube into the support tube 801 at the position of the material box bracket 5, and then start the transmission motor 605 to rotate the turntable 606, so that the concave disk 607 and the movable pin 608 on the top of the turntable 606 periodically cooperate with the cross-shaped plate 603. When the movable pin 608 rotates to the inner position of the movable groove 604 on the surface of the cross-shaped plate 603, the movable pin 608 rotates ninety degrees with the cross-shaped plate 603, so that the cross-shaped plate 603 rotates ninety degrees with the eight support tubes 801 on the adjustment disk 3, and the positions of the two support tubes 801 at the bottom of the material box bracket 5 and the drug adder 2 are switched;

[0060] S2, then start the electric telescopic rod 905 to extend, and during the sliding process of the horizontal pin 906 on the surface of the electric telescopic rod 905 and the waist-shaped groove 904 on the pull block 903, the pull block 903 moves the fixedly connected baffle 902 toward the outside of the L-shaped discharge barrel 901, so that the fruit and vegetable debris inside the L-shaped discharge barrel 901 falls into the corresponding reagent tube, completing the quantitative loading;

[0061] S3, when the adjusting disk 3 rotates 90 degrees with the loaded support cylinder 801 and the reagent tube again, the support cylinder 801 and the reagent tube rotate to the bottom position of the reagent adding device 2, and the reagent adding device 2 adds the detection reagent to the inside of the reagent tube, and then the adjusting disk 3 continues to rotate 90 degrees with the support cylinder 801 and the reagent tube after the reagent is added. At this time, the support cylinder 801 moves to the position of the arc-shaped rack 804. During the meshing process between the circular gear 802 at the lower part of the support cylinder 801 and the arc-shaped rack 804, the support cylinder 801 is rotated to the bottom position of the reagent adding device 2. 01 brings the reagent tube after adding the medicine to rotate synchronously inside the adjustment disk 3 to oscillate. At the same time, the vertical rod 7 on the top of the turntable 606 brings the transmission half gear 806 to mesh with the synchronous gear 807 in stages, so that the synchronous gear 807 that rotates in stages meshes with the synchronous rack 805 and brings the arc rack 804 to move along the arc groove 803 track. Under the action of the reset spring, the arc rack 804 moves back and forth, bringing the support tube 801 and the reagent tube after adding the medicine to rotate back and forth to oscillate.

[0062] S4. Finally, when the adjusting disk 3 rotates to the side wall position of the adjusting bracket 4 with the vibrated supporting cylinder 801 and the reagent tube, as the vertical rod 7 rotates with the cam 808, the cam 808 will periodically press the adjusting rod 809 to move toward the adjusting bracket 4. During the process of the cam 808 pressing the adjusting rod 809, the adjusting disk 3 is in a state of stopping rotation. At this time, the adjusting rod 809 cooperates with the inclined groove 811 on the U-shaped adjusting plate 810 to slide with the adjusting pin 813 at the bottom of the adjusting rack 812, so that the adjusting rack 812 rises to the limit position. During this process, the adjusting rack 812 meshes with the gear rod 814 on the upper part of the adjusting bracket 4 for transmission, so that the gear rod 814 flips with the swing plate 815, and the flipped swing plate 815 brings the hinged pull plate 816 to slide vertically along the inside of the U-shaped block 820. At the same time, the swing plate 815 will move the U-shaped block 820 and the moving block 819 to the left inside the moving groove 818, so that the pull plate 816 moves with the clamp 822 on the transfer plate 821 to the upper part of the support cylinder 801 on the right side of the adjusting disk 3 to clamp the reagent tube. After the cam 808 that continues to rotate releases the pressure on the adjusting rod 809, the adjusting rod 809 and the U-shaped adjusting plate 810 are reset and moved under the action of the return spring, so that the adjusting rack 812 moves down and resets. After the adjusting rack 812 moves down to the extreme position, the gear rod 814 reverses the swing plate 815 180 degrees, so that the swing plate 815 slides upward with the pull plate 816 inside the U-shaped block 820, and at the same time moves the clamped reagent tube to the right side of the moving groove 818, and transfers the vibrated reagent tube to the inside of the placement tube 11.
