Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-6 , a starch product production and pulping device in this embodiment includes a support frame 1, a drive motor 9, a cover plate 3 and a mixing tank 4, all of which are existing structures. The cover plate 3 is installed above the mixing tank 4 through bolts and nuts for sealing. The mixing tank 4 is rotatably installed in the support frame 1. The support frame 1 is provided with a rotating assembly 2 for driving the mixing tank 4 to rotate. The mixing tank 4 is provided with a cover plate 3. A rotatable mixing shaft 5 is vertically arranged in the mixing tank 4. A plurality of mixing rods 6 are fixed on the outer side of the mixing shaft 5. The drive motor 9 is fixedly installed on the cover plate 3, and the output shaft of the drive motor 9 penetrates into the cover plate 3. An installation mechanism 7 is arranged in the mixing tank 4, and a scraping assembly 8 is arranged in the mixing tank 4.

[0026] The installation mechanism 7 includes a first rectangular groove 707, a second rectangular groove 709, and a through groove 711. The upper end of the stirring shaft 5 is provided with the second rectangular groove 709, and the output shaft of the driving motor 9 is provided with the first rectangular groove 707 corresponding to the second rectangular groove 709. A rectangular block 708 corresponding to the second rectangular groove 709 is slidably connected in the first rectangular groove 707.

[0027] A through groove 711 is provided in the stirring shaft 5. The through groove 711 communicates with the second rectangular groove 709. A sliding rod 702 is slidably installed in the second rectangular groove 709. One end of the sliding rod 702 is fixed to the lower end of the rectangular block 708. A first spring 712 is sleeved on the sliding rod 702. The two ends of the first spring 712 are respectively connected to the rectangular block 708 and the second rectangular groove 709.

[0028] The other end of the sliding rod 702 penetrates outside the stirring shaft 5 and the stirring tank 4 and is fixedly connected to a handwheel 701. The lower end of the stirring shaft 5 penetrates outside the stirring tank 4. A retaining ring 710 is fixed to the outer side of the sliding rod 702. A limiting sliding plate 703 is installed on the upper outer wall of the stirring tank 4.

[0029] When the device is in use, when the driving motor 9 drives the stirring shaft 5 to rotate, the cover plate 3 is installed on the upper end of the stirring tank 4 through bolts. Through the arrangement of the first spring 712, a part of the rectangular block 708 slides from the second rectangular groove 709 into the first rectangular groove 707 at the lower end of the output shaft of the driving motor 9. Then, when the driving motor 9 works at this time, the stirring shaft 5 is driven by the rectangular block 708 to rotate in the stirring tank 4 to stir the raw materials.

[0030] When it is necessary to pour the raw materials in the stirring tank 4, the rotating motor drives the stirring tank 4 to rotate to a horizontal position. Then, by pulling the rectangular block 708 downward to separate it from the output shaft of the driving motor 9, at this time, the cover plate 3 is disassembled from the stirring tank 4, and the stirring shaft 5 and the driving motor 9 are separable. After the cover plate 3 is disassembled, it is not necessary to take out the stirring shaft 5 from the stirring tank 4 either, which facilitates the pouring of the reacted raw materials in the stirring tank 4.

[0031] Among them, the sliding rod 702 is circular, which is convenient for the sliding rod 702 to slide in the through groove 711. The stirring shaft 5 can be rotated by rotating the handwheel 701. Since the rectangular block 708 is located in the second rectangular groove 709, the stirring rod 6 can rotate accordingly, so as to adjust the correspondence between the rectangular block 708 and the first rectangular groove 707 at the lower end of the driving motor 9, so that the rectangular block 708 slides into the first rectangular groove 707 for transmission. The first spring 712 is located in the second rectangular groove 709, and the retaining ring 710 is located at the lower end of the stirring shaft 5 and is in contact with it, so as to prevent the rectangular block 708 from moving out of the second rectangular groove 709 when the rectangular block 708 is separated from the first rectangular groove 707.

[0032] Meanwhile, the installation mechanism 7 includes a slider 704. The two sides of the cover plate 3 are fixed with the slider 704. A chute 705 that slidably cooperates with the slider 704 is provided inside the limit slide plate 703. One side of the limit slide plate 703 is fixed with a cylinder 706. The output end of the cylinder 706 is fixed with the cover plate 3. When it is necessary to open the cover plate 3, the rectangular block 708 is separated from the output shaft of the driving motor 9. The lower end surface of the output shaft of the driving motor 9 is higher than the upper end surface of the mixing tank 4. Thus, the cover plate 3 slides along the limit slide plate 703 to open the mixing tank 4. The limit slide plate 703 can limit the cover plate 3, facilitating the opening and closing of the cover plate 3.

[0033] In addition, the rotating assembly 2 includes a rotating motor. The rotating motor is installed on one side of the support frame 1. One end of the rotating motor is fixedly connected to the outer wall of the mixing tank 4. By starting the rotating motor, the rotating motor drives the mixing tank 4 to rotate, and then pouring is carried out.

[0034] Please refer to Figure 1 and Figure 3 In this embodiment, the scraping assembly 8 includes a cavity 801. A cavity 801 is provided at one end of the stirring rod. A second spring 802 is arranged inside the cavity 801. One side of the second spring 802 is connected to a fixed rod 803. A scraper 804 is fixed at the end of the fixed rod 803. The scraper 804 and the cavity 801 form an elastic telescopic structure through the fixed rod 803 and the second spring 802.

[0035] When the stirring rod 6 rotates, the scraper 804 can scrape the raw materials adhered to the inner wall of the mixing tank 4. And under the action of the second spring 802 itself, it can push the fixed rod 803 to move horizontally, enabling the scraper 804 to better contact the inner wall of the mixing tank 4, thereby improving the scraping effect.

[0036] The working principle of the above embodiment is as follows:

[0037] During use, when the driving motor 9 drives the stirring shaft 5 to rotate, the cover plate 3 is installed on the upper end of the mixing tank 4 through bolts. Due to the arrangement of the first spring 712, a part of the rectangular block 708 slides from the second rectangular groove 709 into the first rectangular groove 707 at the lower end of the output shaft of the driving motor 9. Then, when the driving motor 9 works at this time, the rectangular block 708 drives the stirring shaft 5 to rotate in the mixing tank 4 to stir the raw materials.

[0038] When it is necessary to pour the raw materials in the mixing tank 4, the rotating motor drives the mixing tank 4 to rotate to a horizontal position. Then, by pulling the rectangular block 708 down to separate it from the output shaft of the driving motor 9, at this time, the cover plate 3 is disassembled from the mixing tank 4, and the stirring shaft 5 and the driving motor 9 are separable. After the cover plate 3 is disassembled, it is not necessary to take out the stirring shaft 5 from the mixing tank 4 either, which facilitates the pouring of the reacted raw materials in the mixing tank 4.

[0039] During use, by starting the cylinder 706, the cylinder 706 drives the cover plate 3 to move. The cover plate 3 slides within the limit slide plate 703, enabling the cover plate 3 to close and open the mixing tank 4. When closing the mixing tank 4, simply move the cover plate 3 until it abuts against the inner wall of the limit slide plate 703. Without adjusting the cover plate 3, bolts and nuts can be used to seal it with the mixing tank 4. At the same time, when the mixing tank 4 rotates and tilts, the threaded rod can restrict the cover plate 3 to prevent it from sliding, facilitating the pouring and discharging of the reacted raw materials.

[0040] When cleaning the inner peripheral wall of the mixing tank 4, the drive motor 9 drives the mixing shaft 5 to rotate, and then the mixing shaft 5 drives the mixing rod 6 to rotate, so that the scraper 804 can scrape the raw materials adhering to the inner wall of the mixing tank 4. And under the action of the second spring 802 itself, it can push the fixed rod 803 to move horizontally, enabling the scraper 804 to better contact the inner wall of the mixing tank 4, thereby improving the scraping effect.
