DETAILED DESCRIPTION

[0026] The present invention will be further described below by way of embodiments in conjunction with the accompanying drawings.

[0027] refer to Figures 1 to 7 A positioning and shaking device for a conical bottle includes a frame assembly and a shaking device. The frame assembly includes a base plate 1, a frame platform 2 and a cover shell 3. The base plate 1 is arranged at the bottom of the frame platform 2. The shaking device moves inside the frame platform 2 and reciprocates horizontally on the base plate 1. The cover shell 3 is arranged on the top of the frame platform 2 to protect the shaking device.

[0028] The rocking bed device includes a carrier 4 and a driving motor 5. The carrier 4 is provided with a plurality of placement platforms 6 evenly distributed in a rectangular array. The placement platforms 6 include two symmetrically arranged support bars 61 and a tray 62. The support bar 61 is provided with a placement groove 15 extending along its length direction. The placement groove 15 and the first end of the support bar 61 form a step surface 7. The two sides of the bottom of the tray 62 are respectively matched with the corresponding two adjacent placement grooves 15, so that the bottom of the tray 62 is respectively adapted to the step surfaces 7 of the corresponding two support bars 61. The support bar 61 is provided with a side stopper 10 adapted to the tray 62, and the opposite sides of the two side stops 10 of the storage platform are used to limit the two sides of the tray 62. The storage platform limits the tray 62 by the step surface 7 and the side stops 10 of the support bar 61. The side stops 10 are used to limit the front side of the tray 62. The second end of the support bar 61 is provided with a baffle block 16 for limiting the rear side of the tray 62. The second end of the support bar 61 is provided with a first photoelectric sensor 17. When the shaking device is actually used, the first photoelectric sensor 17 cooperates with the corresponding tray 62. The first photoelectric sensor 17 is used to sense the position of the tray 62, thereby feeding back the placement status of the tray 62 of each placement platform 6 on the carrier 4.

[0029] A plurality of clamping structures 9 are installed in the placement cavity 8 of the tray 62 in a rectangular array and at intervals. The clamping structure 9 includes a mounting portion 91 and a plurality of elastic clips 92 circumferentially arranged on the mounting portion 91. Each elastic clip 92 is vertically and obliquely arranged on the mounting portion 91 to form a clamping cavity for clamping the conical bottle 32. The ends of the elastic clips 92 are bent outward to form guide pieces 14. The guide pieces 14 on the clamping structure 9 cooperate with each other to form a hole for the bottom of the conical bottle 32 to be inserted. When the conical flask 32 is placed on the clamping structure 9, the bottom of the conical flask 32 squeezes the guide pieces 14, and the guide pieces 14 are deformed outward so that the conical flask 32 can be moved to the mounting portion 91. The bent portion between the guide pieces 14 and the elastic clip pieces 92 is pressed against the conical flask 32 by the elastic force of the elastic clip pieces 92, so as to locate the position of the conical flask 32 on the tray 62, thereby preventing the conical flask 32 from being displaced or tipped over in the placement cavity 8 due to external force.

[0030] The bottom of the object carrier 4 is symmetrically provided with a first crossbar 18 and a second crossbar 20. The first crossbar 18 is provided with two directional rollers 12. The travel direction of the directional rollers 12 is the same as that of the first crossbar 18. The second crossbar 20 is provided with two guide mounting plates 28. The guide mounting plates 28 are provided with two guide members 11. The bottom plate 1 is provided with a linear guide rail 21 extending along the length direction of the second crossbar 20. The linear guide rail 21 is slidably connected with the corresponding guide member 11. Preferably, the linear guide rail 21 is an optical axis guide rail. The sliding direction of the guide member 11 is the same as that of the travel direction of the directional roller 12.

[0031] The driving motor 5 is installed on the base plate 1. Two mounting rods 22 are symmetrically installed between the first cross bar 18 and the second cross bar 20. The driving motor 5 is located between the two mounting rods 22. Adjusting parts 23 are provided on opposite sides of the two mounting rods 22. The output shaft of the driving motor 5 is provided with an eccentric wheel 24. The eccentric wheel 24 has an eccentric hole 25 for installing the output shaft of the driving motor 5. The eccentric wheel 24 is located between the two adjusting parts 23. The eccentric wheel 24 is sleeved with a bearing part 26. When the eccentric wheel 24 rotates eccentrically, the bearing part 26 conflicts with any one of the two adjusting parts 23, thereby driving the object carrier 4 to reciprocate horizontally on the base plate 1.

[0032] The bottom plate 1 is provided with a limit plate 13, and the upper part of the limit plate 13 exposes the first cross bar 18 and is bent to form a limit plate 19, which is matched with the top of the first cross bar 18. The carrier 4 realizes horizontal reciprocating motion through the guide 11 and the directional roller 12, and the motion is stable. In this process, the carrier 4 drives each tray 62 to synchronously reciprocate horizontally. The limit plate 19 is used to limit the horizontal reciprocating motion of the carrier 4 to prevent the carrier 4 from being bumped during the movement. The conical bottles 32 are respectively positioned and placed by the clamping devices on the tray 62, so that multiple conical bottles 32 can be shaken quickly while preventing sliding and tipping. The cleaning ensures the oscillation and shaking effect of the shaking device on each conical bottle 32, and is convenient for taking and placing, simple to operate, and highly practical.

[0033] The two mounting rods 22 are mounted with a motor cover 27 , which covers the drive motor 5 , the eccentric wheel 24 and the two adjusting members 23 .

[0034] When the shaking device is in use, the staff cuts the sample into pieces and puts them into conical flasks 32 containing extraction liquid respectively, and places each conical flask 32 on a tray 62 respectively. Preferably, the tray 62 is also equipped with a label plate 31 so that the staff can attach an identification label to the label plate 31. The first side opening of the cover shell 3 corresponds to the discharge side of the carrier 4, so that the tray 62 can be placed on the corresponding placement platform 6. After the trays 62 on the carrier 4 are placed, the drive motor 5 is started to drive the carrier 4 as a whole to perform horizontal reciprocating motion, so as to oscillate and shake the conical flask 32 on the tray 62. Preferably, a photoelectric sensor is provided on the top surface of the guide mounting plate 28, and a sensing element 29 is provided on the bottom plate 1. The photoelectric sensor cooperates with the corresponding sensing element 29. The photoelectric sensor is used to record the number of horizontal reciprocating motions of the carrier 4. The shaking device presets the number of oscillations through an external controller until the number of horizontal reciprocating motions of the carrier 4 reaches a preset value. The drive motor 5 stops, and the second side opening of the cover shell 3 corresponds to the material taking side of the carrier 4, so that the tray 62 can be taken out from the placement platform 6 for the next stage of PH testing.

[0035] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
