The transmission gear 412 comprises a driving wheel 4121 and a driven wheel 4122, and the number of the second grooves is two; the driving wheel 4121 and the driven wheel 4122 are respectively arranged in the second grooves, and a transmission shaft of the driving assembly is connected with the driving wheel 4121. On the tooth surface of the rack, there are two gears, one as a driving wheel 4121 to provide power, and the other as a driven wheel 4122 to assist the rack movement.

An integrated withdrawing pipe head is further arranged below the adapter plate 4112 and is used for being connected with the straw assembly 41 b; the integrated pipe withdrawing head is also provided with a withdrawing pipe piece 4113. The pipe withdrawing piece 4113 is arranged for unloading the suction pipe assembly arranged on other unit plates, and because the scheme of the utility model can independently control a certain unit plate to move up and down, the pipe withdrawing operation at any position can be realized; for example, when three adjacent unit plates are arranged together, if the straw assembly mounted at the middle unit plate needs to be removed, the following control mode can be performed: the left unit plate or the right unit plate is fixed, the middle unit plate is controlled to move upwards at the moment, and when a certain position is reached, the pipe withdrawing piece of the left unit plate or the pipe withdrawing piece of the right unit plate is abutted to the sucking pipe assembly of the middle unit plate so as to realize pipe withdrawing operation. It should be noted that when the pipe withdrawing piece is installed at the same position, the installation heights are different, so that the different unit plates can be ensured to be close to each other, and the situation that the space is insufficient due to the fact that the pipe withdrawing piece is located at the same position is avoided; and the structure of the pipe withdrawing piece is a double-U-shaped piece structure, so that the installation and the connection are convenient.

The solution provided by the embodiment of the present invention further includes a sensing assembly 43, where the sensing assembly 43 includes a sensor 431 and a sensing tab 432, the sensor 431 is disposed at the interposer 4112, and the sensing tab 432 is disposed at the unit board 42. The sensing assembly 43 is used for positioning convenience, and when the sensor 431 detects the corresponding sensing piece 432, the action state of the corresponding motor can be controlled.

The foregoing is considered as illustrative of the preferred embodiments of the utility model and technical principles employed. The present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model. Therefore, although the present invention has been described in more detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the claims.
