Detailed ways

Referring to FIGS. 1-3 , a sampling tube feeding mechanism includes a support 1 on which a horizontal sample tube conveyor belt 2 is provided, and a sample tube conveyor belt 2 is provided on the support 1 above the initial end of the sample tube conveyor belt 2 The bevel toothed plate 3 whose axis is perpendicular to the conveying direction of the sample tube conveyor belt 2, the plane where the tooth top of the bevel toothed plate 3 is located is perpendicular to the side wall of the sample tube conveyor belt 2, the bevel toothed plate 3. The plane where the tooth top of the bottom end is located is parallel to the conveying surface of the sample tube conveyor belt 2, and the bracket 1 is provided with a conical arc coaxial with the bevel tooth plate 3 on the tooth top side of the bevel tooth plate 3. The two end points of the conical arc baffle 4 correspond to the tooth crest of the tooth 5 at the top of the bevel tooth plate 3 and the tooth crest of the tooth 5 at the bottom end of the bevel tooth plate 3 respectively. The arc-shaped concave direction of the baffle plate 4 faces the conveying direction of the sample tube conveying belt 2 .

In the present utility model, when in use, the sampling tube 11 located at a relatively high station is transmitted to the tooth slot on the upper end of the bevel toothed plate 3 through the conveyor belt or the conveyor chain, because the bevel toothed plate 3 is relatively located at the top of the bevel toothed plate 3 . The plane where the tooth top of the tooth 5 is located is vertical and parallel to the side wall of the sample tube conveyor belt 2, and the bracket 1 is provided with a coaxial with the bevel tooth plate 3 on the tooth top side of the bevel tooth plate 3. The conical arc baffle 4, that is to say, the setting of the conical arc baffle 4 prevents the sampling tube 11 located in the tooth slot from leaving the bevel tooth plate 3 during the rotation of the bevel tooth plate 3, and the conical arc shape The two end points of the baffle plate 4 correspond to the tooth crest of the tooth 5 at the top end of the bevel toothed plate 3 and the tooth crest of the toothed tooth 5 at the bottom end of the bevel toothed plate 3 respectively. Describe the conveying direction of the sample tube conveyor belt 2, that is to say, the conical arc baffle 4 directly blocks half of the tooth grooves of all the tooth grooves on the bevel tooth plate 3, and blocks the bevel tooth plate 3 close to the sample tube conveyor belt. 2 All the tooth slots on the side of the initial end, therefore, the sampling tube 11 rotates with the bevel tooth plate 3 during the rotation of the bevel tooth plate 3 until it moves to the lowest point on the bevel tooth plate 3, that is, the bevel tooth plate 3. The position closest to the sample tube conveyor belt 2 will leave the bevel gear plate 3 and enter the sample tube conveyor belt 2 under the action of gravity, and then move to the preset station along with the sample tube conveyor belt 2. In this process, one tooth slot conveys one sampling tube 11, so that even under the action of the sampling tube 11's own gravity, the collision between the sampling tubes 11 will not occur when moving to the sampling tube conveyor belt 2 . Ordinary conveyor belts can also be used on the sample tube conveyor belt 2 with some devices specially used for placing sampling tubes 11, or some slots for placing sampling tubes 11 can be set on the ordinary conveyor belt, or ordinary conveyor belts can be used. The conveying surface of the conveyor belt is set as a rough surface with great friction, and even the conveying speed of the ordinary conveyor belt can be slowed down, etc., to prevent the sampling tube 11 from rolling.

In order to make the functions of the present invention more perfect, so that the user can use the device of the present invention without adding additional auxiliary to prevent the sample tube conveyor belt 2 from rolling, a number of sample tubes are arranged on the conveying surface of the sample tube conveyor belt 2 Slot 6, the axis of the sample tube slot 6 is set horizontally, and the axis of the sample tube slot 6 is perpendicular to the conveying direction of the sample tube conveyor belt 2, and the upper surface of the sample tube slot 6 is located on the bevel gear plate 3 After this setting, the conveying speed of the sample tube conveyor belt 2 can be adjusted to match the rotation speed of the bevel gear plate 3, so that the sampling tube 11 falling from the tooth slot of the bevel gear plate 3 to the sample tube conveyor belt 2 directly falls into the sample tube slot 6 so that the sample tube 11 will not roll and collide during the movement of the sample tube conveyor belt 2 .

As a preferred way, the bracket 1 is also provided with a straight vibration machine 7, and the discharge nozzle 8 of the straight vibration machine 7 is horizontally arranged and aligned with the tooth crest of the tooth 5 at the top of the bevel tooth plate 3, The sampling tube 11 is fed into the tooth slot of the bevel gear plate 3 by the direct vibration machine 7 .

Further, on the basis of setting the straight vibration machine 7, the end of the discharge nozzle 8 of the straight vibration machine 7 is provided with an arc-shaped material guide section 9, and the arc-shaped concave direction of the arc-shaped material guide section 9 is toward the At the initial end of the sample tube conveyor belt 2, the setting of the arc-shaped material guide section 9 can change the movement direction of the sampling tube 11 conveyed from the direct vibration machine 7. Since the arc-shaped depression direction of the arc-shaped material guide section 9 is toward the The initial end of the sample tube conveyor belt 2 reduces the angle between the movement direction of the sample tube 11 after it exits the discharge nozzle 8 and the direction of the linear velocity of the top of the bevel gear plate 3, thereby reducing the distance between the sample tube 11 and the bevel teeth. The impulse between the inner walls of the tooth slots of the disc 3 prevents damage to the sampling tube 11 .

As a preferred way, the distance from each point on the inner surface of the conical arc baffle plate 4 to the tooth top of the bevel tooth plate 3 is the same. The purpose of this setting is to make the sampling tube 11 in the bevel tooth plate It can be tightly clamped by the conical arc baffle 4 and the inner wall of the tooth slot, and at the same time, the pressure exerted by the conical arc baffle 4 and the inner wall of the tooth slot on the sampling tube 11 is uniform.

As a preferred way, the width of the conical arc baffle plate 4 is smaller than the tooth width of the toothed teeth 5. The purpose of this setting is to enable the device of the present invention to transport sampling tubes 11 of different lengths, and to increase usage scenarios. Of course, from the perspective of production cost, the use rate is improved, and the production cost of the conical arc baffle 4 is also saved.

As a preferred method, see FIG. 3 , the tooth 5 is provided with a chamfer 10 on the side facing away from the rotation direction of the bevel ring 3 . The edge of the opening is convenient for the sampling tube 11 to enter the tooth slot of the bevel toothed plate 3, and at the same time, when the sampling tube 11 moves with the bevel toothed plate 3 to the lowest point of the bevel toothed plate 3, it is convenient for the sampling tube 11 to enter the sampling tube 11.
