The sampling tube 10 sucks the sample liquid from the middle part of the filter screen 20.
[0030] In use, the mechanical arm clamps the sampling tube 10, moves to the placement position of the filter screen 20, connects the sampling tube 10 and the filter screen 20 together, and then moves to the sample to be detected together, inserts the filter screen 20 into the sample to be detected, and then the sample liquid filtered through the filter screen 20 enters the middle part of the filter screen 20, the sampling tube 10 sucks the sample liquid from the middle part of the filter screen 20 and is separated from the filter screen 20 under the action of the mechanical arm, and then the subsequent detection process is performed.
[0031] The fruit-particle beverage automatic sampling device provided by the embodiment of the utility model, the mechanical arm clamps the sampling tube 10 and the filter screen 20 after being connected and inserts into the sample liquid together, filters and samples simultaneously, compared with the mode of filtering first and sampling later, without waiting for the completion of filtering and the replacement of the sampling tube 10 and the filter screen 20, the sampling efficiency is high.
[0032] In a specific embodiment, as shown in Figure 3 and Figure 4 The filter screen 20 includes a filter cylinder 22 and a connecting rod 21. The connecting rod 21 is fixed to the open end of the filter cylinder 22, and the sampling tube 10 is buckled with the connecting rod 21.
[0033] The circumferential side wall and the bottom wall of the filter cylinder 22 are provided with filter holes to prevent fruit particles from entering the filter cylinder 22. The connecting rod 21 is provided to provide a setting position for the buckle of the sampling tube 10, so as to be connected with the connecting rod 21. For example, the connecting rod 21 is a U-shaped rod, both ends of which are connected with the filter cylinder 22, and the connecting points of the connecting rod 21 and the filter cylinder 22 are located on the same diameter line. For another example, a plurality of connecting rods 21 are connected to the filter cylinder 22 in an umbrella shape.
[0034] In an embodiment, as shown in Figure 4 The filter cylinder 22 includes a first filter cylinder 221 and a second filter cylinder 222, the filter hole size of the first filter cylinder 221 is larger than that of the second filter cylinder 222, the first filter cylinder 221 is sleeved outside the second filter cylinder 222 and has a spacing with the second filter cylinder 222, and both the first filter cylinder 221 and the second filter cylinder 222 are fixed to the connecting rod 21.

As shown in Figure 4 The first filter cylinder 221 and the second filter cylinder 222 are connected through a connecting ring 24. The inner ring of the connecting ring 24 is fixedly connected with the outer wall of the second filter cylinder 222, and the outer ring of the connecting ring 24 is fixedly connected with the inner wall of the first filter cylinder 221. In a specific embodiment, the connecting rod 21 is a U-shaped rod, which can be installed on the first filter cylinder 221 or the second filter cylinder 222.
[0036] In another specific embodiment, as shown in Figure 4As shown, the fruit-particle beverage automatic sampling device further comprises a connecting seat 23, the connecting rods 21 are multiple, one end of each connecting rod 21 is fixedly connected with the connecting seat 23, and the other end is fixedly connected with the open end of the filter cylinder 22, and the buckle is arranged on the connecting seat 23. Figure 5 As shown, the sampling tube 10 is provided with an elastic clamping head 50, the connecting seat 23 is provided with a clamping hole, and when the elastic clamping head 50 is clamped into the clamping hole, the sampling tube 10 is fixedly connected with the connecting seat 23.

It should be noted that the position of the groove arranged on the sampling tube 10 is close to the upper part of the sampling tube 10, and the corresponding position in the interior has a channel but does not accommodate sample liquid, so as to avoid that the arrangement of the elastic clamping head 50 affects the normal sampling of the sampling tube 10.
[0037] The fruit-particle beverage automatic sampling device provided in the embodiment of the utility model, sample liquid enters the interior of the second filter cylinder 222 after being filtered by the first filter cylinder 221 and the second filter cylinder 222, double-layer filtering is provided by the first filter cylinder 221 and the second filter cylinder 222, and the fruit particles are prevented from blocking the sampling tube 10 and affecting sampling.

[0039] In the case that the filter screen 20 comprises the first filter cylinder 221 and the second filter cylinder 222, the sealing connector 30 is arranged at the cylinder opening of the second filter cylinder 222. The sealing connector 30 is provided with the tapered hole 31, the minimum aperture of the tapered hole 31 is consistent with the outer diameter of the sampling tube 10, the large-diameter end of the tapered hole 31 faces outward, and the sampling tube 10 is conveniently inserted into the tapered hole 31. The mechanical arm drives the sampling tube 10 to be inserted into the tapered hole 31, and the sampling tube 10 is fixed by the small-diameter end of the tapered hole 31.
[0040] In a specific embodiment, as shown, Figure 2 The fruit-particle beverage automatic sampling device further comprises a storage rack 40, and the storage rack 40 is provided with multiple storage grooves 41, and one filter screen 20 can be accommodated in each storage groove 41.
[0041] Specifically, the receiving frame 40 is fixed on the operation table. The size of the receiving groove 41 is matched with the size of the filter screen 20. When the filter screen 20 is placed in the receiving groove 41, the groove wall of the receiving groove 41 can constrain the filter screen 20 to avoid the filter screen 20 shaking left and right. When the mechanical arm drives the sampling tube 10 to connect with one of the filter screens 20, the groove bottom of the receiving groove 41 can provide support for the filter screen 20, push the filter screen 20 to connect with the sampling tube 10, and move the whole to the sampling position to sample from the sample to be tested.

When sampling, the mechanical arm drives the sampling tube 10 to connect with the filter screen 20, pushes the filter screen 20 and the sliding table to move downward to the sampling position, and inserts the filter screen 20 into the sample to be tested. Then, the mechanical arm drives the sampling tube 10 to continue to move downward, so that the sampling tube 10 is stably connected with the filter screen 20. Thus, through the single action of the mechanical arm driving the sampling tube 10, filtering and sampling can be realized.
[0043] Optionally, the filter screens 20 in different receiving grooves 41 have different mesh numbers. According to the type of the sample to be tested, a suitable filter screen 20 is selected for filtering. For example, strawberries are relatively soft, and a filter screen 20 with a relatively large mesh number is selected. Mangoes, yellow peaches and the like are in block shape, and a filter screen 20 with a relatively large mesh number is selected.

The straight tube segment is fixed to the mechanical arm, and the large-diameter end of the frustum segment is fixed with a filter element.
[0045] The large-diameter end of the frustum segment is the inlet of the sampling tube 10. In order to prevent residual fruit particles in the sample liquid, a filter element is fixedly installed at the large-diameter end of the frustum segment. The filter element is embedded in the inner wall of the frustum segment in a mesh shape, or the filter element is integrally formed with the frustum segment.
[0046] In an optional embodiment, the filter element is in the form of a sieve net and is integrally formed with the frustum segment. Specifically, the sampling tube 10 is a stainless steel tube, the end of which is provided with a sieve net as a filter element, and the mesh number of the sieve net is set according to the needs. In yet another optional embodiment, the filter element is a flexible net which is sleeved and fixed to the sampling tube 10.
