[0032] like Figure 2 , Figure 4 as well as Figure 6-7 As shown, according to another embodiment of the utility model, the limiting device of the pressure rod of the ash roasting machine is further optimized in terms of the limiting part, the operating part, the first limiting piece and the second limiting piece included therein, the limiting part includes a limiting sleeve 6 coaxially rotatably mounted on the upper part of the support ring 2, the upper end surface of the limiting sleeve 6 is provided with a notch 61, the distance between one end of the notch 61 and the support ring 2 from the other end gradually decreases along the circumferential direction of the limiting sleeve 6, the rotational connection between the pressure rod 8 and the support ring 2 is located in the limiting sleeve 6, the lower part of the pressure rod 8 slides against the side wall of the notch 61, the operating part is fixedly mounted on the outer wall of the limiting sleeve 6, and the first limiting piece is arranged near the high end of the notch 61; preferably, a column 21 is fixedly mounted on the support ring 2, the column 21 is located in the limiting sleeve 6, and two brackets 22 are fixedly mounted opposite to each other on one end of the column 21 away from the support ring 2, the pressure rod 8 is rotatably mounted between the two brackets 22 to ensure the stability of the rotation of the pressure rod 8.

[0033] The operating part includes an operating rod 66 fixedly installed on the outer wall of the limiting sleeve 6 along the radial direction. The second limiting member is arranged on the supporting ring 2 and is located on the rotation trajectory of the operating rod 66. Preferably, the second limiting member includes a limiting plate 23 fixedly installed on the supporting ring 2 along the radial direction, and the limiting plate 23 is located on the rotation trajectory of the operating rod 66, so as to limit the rotation position of the operating rod 66.

When the pressure rod 8 is out of contact with the limit block 63, the limit block 63 is reset by the elastic action of the spring 65 to limit the position of the pressure rod 8, and the joint action of the baffle plate 64 and the limit block 63 makes it impossible for the limit sleeve 6 to slide relative to the pressure rod 8, thereby fixing the position of the pressure rod 8.

[0035] like Figure 2-4 As shown, according to another embodiment of the utility model, the pressure rod limiting device of the ash roasting machine is preferably further optimized in that the stirring mechanism included therein is evenly provided with a plurality of slots 12 on the end surface of the barrel mouth of the stirring barrel 1 along its circumference, and a sealing plate 3 is provided between the inner and outer sides of the stirring barrel 1, and a plurality of blocks 31 are fixedly installed on the side wall of the sealing plate 3 along its circumference, and a plurality of the blocks 31 are engaged with the plurality of slots 12 in a one-to-one correspondence, so as to seal the barrel mouth of the stirring barrel 1 through the sealing plate 3 to prevent impurities from falling into the stirring barrel 1 and affecting the quality of the aluminum liquid; a shaft sleeve 4 is installed through the middle part of the sealing plate 3 along its axial rotation, wherein the shaft The sleeve 4 includes two large pipe diameter sections and a small pipe diameter section that are coaxially fixedly connected. The small pipe diameter section is located between the two large pipe diameter sections. The sealing plate 3 is rotatably connected to the small pipe diameter section and is clamped between the two large pipe diameter sections. The bottom of the mixing barrel 1 is coaxially fixedly connected and connected with a discharge pipe 11. The stirring mechanism includes a stirring shaft 5 rotatably arranged in the mixing barrel 1 and a driving member installed on the sealing plate 3. A plurality of stirring blades 51 are fixedly installed on the stirring shaft 5 along its axial direction. The upper end of the stirring shaft 5 is fixedly passed through the sleeve 4 and is connected to the driving member and the pressure rod 8. The lower end of the stirring shaft 5 is used to be inserted into the discharge pipe 11 to close the discharge pipe 11.

[0036] The driving member includes a motor 9 fixedly mounted on the sealing plate 3 through a fixing block 93, and a first bevel gear 91 and a second bevel gear 92 meshing with each other, wherein the first bevel gear 91 is coaxially fixedly connected to the power output shaft of the motor 9, and the second bevel gear 92 is fixedly sleeved on one end of the stirring shaft 5 located outside the stirring barrel 1; the rotation of the motor 9 is driven by the transmission of the first bevel gear 91 and the second bevel gear 92, thereby driving the stirring shaft 5, the shaft sleeve 4 and a plurality of stirring blades 51 to rotate synchronously.

[0037] A connector 7 is fixedly installed on one end of the stirring shaft 5 located outside the stirring barrel 1 and on the end of the pressure rod 8 close to the stirring barrel 1. The two connectors 7 are rotatably connected by a connecting rod 71; the rotation of the pressure rod 8 can drive the stirring shaft 5 and the sealing plate 3 to move upward, thereby separating the stirring shaft 5 from the discharge pipe 11.

[0038] The operating principle of the utility model is as follows: when the utility model is used, when it is necessary to discharge the aluminum liquid produced by the ash roasting and add raw materials into the mixing barrel 1 again, the motor 9 is stopped, and then the limit block 63 is pressed and the spring 65 is compressed at the same time, so that the limit block 63 is retracted into the slide groove 62, and then the operating rod 66 is pulled to drive the limit sleeve 6 to rotate, so that the position where the pressure rod 8 and the limit sleeve 6 abut against each other slides from the high end of the notch 61 to the low end of the notch 61, providing a rotation space for the pressure rod 8. At this time, the pressure rod 8 is rotated to drive the stirring shaft 5, the shaft sleeve 4 and the sealing plate 3 to move out of the mixing barrel 1, and the several blocks 31 on the sealing plate 3 are separated from the groove 12, and the stirring shaft 5 is separated from the discharge pipe 11, so that the aluminum liquid can be discharged from the discharge pipe 11. After the aluminum liquid is discharged, since the sealing plate 3 is separated from the barrel mouth of the mixing barrel 1, the raw materials can be added into the mixing barrel 1. After the raw materials are added, the pressure rod 8 is rotated in the opposite direction to drive the stirring shaft 5, the shaft sleeve 4 and the sealing plate 3 to move into the mixing barrel 1, so that the several blocks 31 on the sealing plate 3 are separated one by one. The plurality of slots 12 are correspondingly inserted, and the stirring shaft 5 is inserted into the discharge pipe 11 to close it. Then, the operating rod 66 is pulled to drive the limit sleeve 6 to rotate in the opposite direction, so that the position where the pressure rod 8 and the limit sleeve 6 abut against each other slides from the lower end of the notch 61 to the higher end of the notch 61. In addition, during the rotation of the limit sleeve 6, the wedge-shaped surface of the limit block 63 abuts against the pressure rod 8, thereby pressing the limit block 63 into the slide groove 62 and compressing the spring 65. When the pressure rod 8 is out of contact with the limit block 63, the spring 65 is used to release the pressure rod 8. The elastic action of the limit block 63 resets the position of the pressure rod 8, and the joint action of the baffle 64 and the limit block 63 prevents the limit sleeve 6 from sliding relative to the pressure rod 8, thereby fixing the position of the pressure rod 8 and ensuring that the positions of the stirring shaft 5 and the sealing plate 3 do not change. Subsequently, the motor 9 is started to drive the stirring shaft 5, the shaft sleeve 4 and the plurality of stirring blades 51 to rotate synchronously through the transmission of the first bevel gear 91 and the second bevel gear 92 to perform stable ash frying.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
