Detailed Implementation

[0024] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0025] like Figure 1 , 2 As shown in Figure 3, a stirring device for coumarin includes a stirring vessel 101. A top cover 102 is detachably mounted on the top of the stirring vessel 101. A stirring shaft 103 is rotatably mounted inside the stirring vessel 101. Stirring blades 104 are mounted on the side end of the stirring shaft 103. A connecting cylinder 105 is rotatably mounted on the top cover 102 and sleeved outside the stirring shaft 103. A scraper 106 is mounted on the connecting cylinder 105 via a crossbar 114 for scraping and cleaning scraper plates 106 adhering to the inner wall of the stirring vessel 101. In this embodiment, the crossbar 114 is welded to the connecting cylinder 105. The side end of the scraper 106 has a fastening groove for engaging with the crossbar 114. A fastening bolt 113 is screwed into the fastening groove for screwing the crossbar 114. Threaded fastening holes are provided on the crossbar 114 for engaging with the fastening bolt 113. Simply make the crossbar 114 snap into the fastening groove 112 and then make the fastening bolt 113 pass through the side wall of the fastening groove and screw it into the threaded fastening hole to achieve flexible fixation of the crossbar 114 and the scraper 106.

[0026] After the worker adds coumarin to the mixing tank 101, the mixing shaft 103 can be driven to rotate, which in turn drives the mixing blades 104 to stir the coumarin in the mixing tank 101. When it is necessary to scrape and clean the coumarin adhering to the inner wall of the mixing tank 101, the connecting cylinder 105 can be driven to rotate, which drives the scraper 106 to rotate through the crossbar 114 to scrape and clean the coumarin adhering to the inner wall of the mixing tank 101.

[0027] This allows the rotation of the connecting cylinder 105 to be independent of the rotation of the stirring shaft 103. Since the stirring shaft 103 and the stirring blades 104 need to continuously stir the coumarin, the scraper 106 can only rotate when scraping and cleaning is needed. Therefore, it can prevent the scraper 106 from easily wearing out in a short time due to the ineffective operation of the stirring shaft 103 for a long time.

[0028] The top cover 102 is also equipped with a feed hopper 108. The lower end of the mixing vessel 101 is conical. The bottom of the mixing vessel 101 is also equipped with a support leg 109 and a discharge pipe 110. A control valve 111 is installed on the discharge pipe 110. Workers can add coumarin to the mixing vessel 101 through the feed hopper 108. After the mixing process is completed, the control valve 111 is opened to discharge the coumarin through the discharge pipe 110. Because the lower end of the mixing vessel 101 is conical, the coumarin can be discharged completely.

[0029] According to another embodiment of the present invention, such as Figure 1 , 3 As shown in Figure 4, a U-shaped mounting bracket 201 is welded onto the top cover 102. A first telescopic push rod 202 is vertically arranged on the mounting bracket 201. A mounting plate 203 is provided at the lower end of the output shaft of the first telescopic push rod 202. The upper end of the stirring shaft 103 passes through the top cover 102 and is rotatably connected to the mounting plate 203 through a first bearing 207. A connection insertion hole 204 is provided at the top of the mounting bracket 201. A connection rod 205 is provided on the mounting plate 203 and is inserted into the connection insertion hole 204.

[0030] During the stirring process of the stirring shaft 103 and stirring blades 104 in the stirring vessel 101, the output shaft of the first telescopic push rod 202 can also be extended and retracted. Through the insertion and engagement of the connecting socket 204, the mounting plate 203 and the stirring shaft 103 can be vertically adjusted, thereby changing and expanding the stirring range of the stirring blades 104 on the coumarin, so as to stir the coumarin more fully and efficiently.

[0031] like Figure 1 , 2 As shown in Figure 3, a drive motor is also installed on the mounting plate 203. A drive gear is installed on the output shaft of the drive motor, and a driven gear 206 that meshes with the drive gear is installed on the upper end of the stirring shaft 103. The worker only needs to drive the drive motor to rotate the stirring shaft 103 through the transmission cooperation of the drive gear and the driven gear 206.

[0032] According to another embodiment of the present invention, such as Figure 1 , 2As shown in Figure 3, a transmission gear 301 is also provided on the connecting cylinder 105, and a vertical plate 302 is also provided on the top cover 102. A second telescopic push rod 303 is horizontally arranged on the vertical plate 302. A rack 304 that meshes with the gear is provided on the output shaft of the second telescopic push rod 303. The rack 304 is also slidably connected to the top cover 102. The top cover 102 is rotatably connected to the connecting cylinder 105 through a second bearing 307. A through hole 308 is provided on the top cover 102 that is rotatably connected to the connecting cylinder 105. The outer ring of the second bearing 307 is connected to the outer wall of the top cover 102, and the inner ring of the second bearing 307 is connected to the connecting cylinder 105. The connecting cylinder 105 passes through the through hole 308 and extends into the interior of the stirring vessel 101.

[0033] like Figure 1 , 2 As shown in Figure 4, a connecting groove 306 is provided on the top cover 102, and a connecting slider 305 that is slidably connected to the connecting groove 306 is provided at the bottom of the rack 304. The slot of the connecting groove 306 and the vertical section of the connecting slider 305 are both T-shaped.

[0034] The worker only needs to drive the output shaft of the second telescopic push rod 303 to extend and retract, and under the sliding cooperation of the connecting slider 305 and the connecting groove 306, the rack 304 will move back and forth, thereby driving the transmission gear 301 to move back and forth, and thus driving the scraper 106 to rotate back and forth.

[0035] According to another embodiment of the present invention, such as Figure 1 , 3 As shown, the top cover 102 is snapped into and fixed to the mixing vessel 101. A U-shaped handle is welded to the top cover 102, allowing for easy movement. The top cover 102 also has a fixing bolt 107 for screwing into the mixing vessel 101, and a threaded fixing hole for screwing into the fixing bolt 107. The worker only needs to snap the top cover 102 into the mixing vessel 101 and then pass the fixing bolt 107 through the side wall of the top cover 102 and screw it into the threaded fixing hole to achieve flexible fixing of the top cover 102 and the mixing vessel 101.

[0036] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
