Among them, the rotating mechanism 100 includes a rotating body 2, and the rotating mechanism 100 is installed on the base plate 500. The rotary evaporator bottle 1 to be discharged is placed on the rotating body 2 and rotates circumferentially with the rotating body 2; the fixing mechanism 200 is installed on the base plate 500.

[0061] That is to say, Figure 1As shown, the discharging equipment includes a rotating mechanism 100, a fixing mechanism 200, a scraping mechanism 300 and a scraping pushing mechanism 400; the rotating mechanism 100 includes a rotating power part (such as a servo motor), a first transmission shaft 6, a rotating body 2, etc., which is used to provide power for the rotation of the rotary evaporator bottle 1, driving the rotary evaporator bottle 1 to rotate at a certain speed.

[0063] In this way, during the working process, after the rotary evaporator bottle 1 is placed in the designated position, the bottle mouth position of the rotary evaporator bottle 1 is fixed by the fixing mechanism 200 to avoid circumferential movement; the rotating mechanism 100 is started, the rotary evaporator bottle 1 rotates under the drive of the rotating body 2, and the scraping mechanism 300 extends into the interior of the rotary evaporator bottle 1 to scrape the material. After the scraping is completed, the scraping pushing mechanism 400 moves in the opposite direction to withdraw the scraping mechanism 300 from the rotary evaporator bottle 1. No manual intervention is required during the scraping process, reducing the contamination of the composite by human factors; the mechanical actions mainly include the rotation of the rotary evaporator bottle 1, the pushing of the scraping mechanism 300, and the rotation of the scraping mechanism 300, with a simple structure and easy operation. The problem of long manual scraping time is solved. Manual scraping takes two hours to complete the scraping, and the scraping can be completed in ten minutes after using the machine, which greatly improves the production efficiency. The discharging equipment for the rotary evaporator bottle realizes scraping through mechanical equipment, improves the discharging efficiency and cleanliness, so as to solve the technical problems of low discharging efficiency of the rotary evaporator bottle and easy contamination of materials in the prior art.

The rotating body 2 is connected to the rotating power piece through a rotating transmission assembly and rotates under the drive of the rotating power piece.

[0065] Specifically, the rotating power part is a rotating motor (such as a servo motor), and a belt drive connection is adopted between the rotating motor and the rotating body 2, that is, the rotating transmission assembly includes a first transmission belt assembly connected to the rotating motor, and the rotating body 2 is a rotating wheel connected to the driven wheel of the first transmission belt assembly.

[0076] The scraper member includes a second transmission shaft 20, a swing arm, a scraper needle seat 27 and a scraper needle 28. The second transmission shaft 20 is connected to the driven wheel of the third transmission belt assembly through a bearing; the swing arm is fixedly connected to the second transmission shaft 20, and when the driven wheel of the third transmission belt assembly rotates, the swing arm rotates horizontally around the second transmission shaft 20; the scraper needle seat 27 is mounted on the swing arm, and the scraper needle 28 is mounted on the scraper needle seat 27. After the scraper mechanism 300 enters the interior of the rotary evaporator bottle 1 through the scraper propulsion mechanism 400, the scraper power member is started, and the third transmission belt assembly drives the second transmission shaft 20 to rotate around its longitudinal axis, thereby driving the swing arm to rotate in the horizontal direction, and then driving the scraper needle 28 to move within a certain range, so as to cooperate with the movement of the rotary evaporator bottle 1 and realize scraping.
