[0028] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 4 as shown in .

[0029] Embodiment 1: A flour mixer, comprising a lower supporting barrel 1, the bottom of which is mounted on the top of a first lifting drive mechanism, an upper inverted barrel 2 is inserted and sealed in the inner cavity of the lower supporting barrel 1, a feeding pipe opening 3 connected to the inner cavity of the upper inverted barrel 2 is arranged on the top of the upper inverted barrel 2, the lower outer wall of the upper inverted barrel 2 is sealed against the inner wall of the lower supporting barrel 1, the bottom of the upper inverted barrel 2 is open and the bottom end is against the bottom of the inner cavity of the lower supporting barrel 1, and the upper inverted barrel 2 is in the middle of the upper inverted barrel 2. An expansion sleeve 4 is integrally formed and fixed on the outer wall of the upper inverted barrel 2, and a jacket cavity 5 for clamping the outer wall of the lower supporting barrel 1 is formed between the expansion sleeve 4 and the middle outer wall of the upper inverted barrel 2. An expansion disk 6 is arranged on the periphery of the expansion sleeve 4, and the bottom two sides of the expansion disk 6 are respectively installed on the top of the second lifting drive mechanism at the corresponding position. A stirring mechanism is installed in the inner cavity of the lower supporting barrel 1, and the lower end of the stirring mechanism is connected to the driving member installed on the first lifting drive mechanism. It should be noted in this embodiment that the lower supporting barrel 1 is located at the bottom as the main supporting structure, and the upper inverted barrel 2 is inserted and inserted above it. The lower supporting barrel 1 and the upper inverted barrel 2 can form an inner cavity for mixing flour and water liquid. When it is necessary to control the feeding into the inner cavity, an appropriate amount of flour is fed into the inner cavity through the feeding nozzle 3. At the same time, the first lifting drive mechanism and the second lifting drive mechanism are controlled to cooperate to achieve the docking and pressing of the lower supporting barrel 1 and the upper inverted barrel 2 to ensure the sealing effect inside. The outer wall of the upper inverted barrel 2 and the inner wall of the lower supporting barrel 1 are inserted to achieve a first seal, and the clamping of the jacket cavity 5 is used to achieve a second seal, thereby achieving the purpose of improving the sealing effect. After the feeding is completed, the driving member is started. When the driving member starts to operate, it can drive the stirring mechanism to drive the flour and water inside to mix and stir quickly into a mass.

[0030] In any of the above schemes, preferably, the driving member includes a stirring motor 7 fixedly installed at the top center of the first lifting drive mechanism, and the top of the motor shaft of the stirring motor 7 is fixedly connected to the lower end of the stirring mechanism.

[0031] The stirring motor 7 is used as a driving component, and can achieve stirring effect and efficiency during the stirring process by controlling its rotation speed and direction during operation.

[0032] In any of the above schemes, it is preferred that the first lifting drive mechanism includes a horizontally arranged supporting chassis 8, and a plurality of first synchronous lifting electric cylinders 9 are arranged at intervals at the bottom of the supporting chassis 8, and each of the first synchronous lifting electric cylinders 9 works in a synchronous lifting state, and the bottom of the cylinder barrel of each of the first synchronous lifting electric cylinders 9 is fixedly installed on the ground, and the stirring motor 7 is fixedly installed at the top center of the supporting chassis 8, and support columns 10 are respectively fixedly installed on both sides of the stirring motor 7, and the bottom of each of the support columns 10 is fixedly installed on the bottom of the lower supporting barrel 1.

[0033] The first lifting drive mechanism as a whole relies on the first synchronous lifting electric cylinder 9 at its bottom as a lifting component. When it is necessary to control each first synchronous lifting electric cylinder 9 to perform synchronous lifting, it can drive the lower supporting barrel 1 and the stirring motor 7 connected at the bottom to achieve synchronous lifting and positioning control. During the stirring process, the lower supporting barrel 1 remains in a locked state.

[0034] In any of the above schemes, it is preferred that the stirring mechanism includes a hollow stirring shaft 11 vertically arranged inside the cavity of the upper inverted barrel 2, the top of the hollow stirring shaft 11 is open and the bottom is closed, and a rectangular scraper frame 12 is fixedly installed on both sides of the outer wall of the hollow stirring shaft 11, and the outer walls of the rectangular scraper frame 12 are abutted against the inner wall of the cavity of the upper inverted barrel 2, and a plurality of horizontal stirring rods 13 are fixedly installed on the inner wall of the inner frame of each of the rectangular scraper frames 12 at intervals along its height direction.

[0035] As an executive structural component, the stirring mechanism mainly relies on the linkage of the stirring motor 7 to drive the hollow stirring shaft 11 to rotate on a fixed axis during operation. When the hollow stirring shaft 11 rotates, it will drive the rectangular scraper frame 12 fixedly connected to its outer wall to scrape the inner wall of the cavity of the upper inverted barrel 2, thereby ensuring the rapid scraping of the dough blocks adhered to the inner wall of the cavity of the upper inverted barrel 2; in addition, during the operation of the hollow stirring shaft 11, the rotating stirring of the horizontal stirring rod 13 can achieve rapid stirring of the flour inside the cavity of the upper inverted barrel 2, thereby improving the stirring effect.

[0036] In any of the above schemes, it is preferred that an outer spiral tube 14 is screwed into the central screw hole of the upper inverted barrel 2 just above the hollow stirring shaft 11, and a water inlet pipe joint 15 is connected to the bottom of the central cavity of the outer spiral tube 14. In the working state, the outer side wall of the lower end of the water inlet pipe joint 15 is sealed and inserted into the inner side wall of the upper cavity of the hollow stirring shaft 11, and a water control valve 16 is fixedly installed on the top of the outer spiral tube 14, and the inlet end of the water control valve 16 is connected to a delivery pipe 17, and the delivery pipe 17 is connected to an external water source.

[0037] The top of the hollow stirring shaft 11 is equipped with a water inlet pipe joint 15 that can be quickly assembled or separated. When installing the water inlet pipe joint 15, the outer screw tube 14 is screwed together to drive it to rise and fall, thereby ensuring that the lower part of the water inlet pipe joint 15 can be quickly sealed and inserted into the inner wall of the upper cavity of the hollow stirring shaft 11. At the same time, when the hollow stirring shaft 11 rotates, no motion interference will occur, thereby ensuring smooth operation.

[0038] When it is necessary to add the matching water into the cavity of the upward inverted bucket 2, the amount of water added can be effectively controlled by controlling the opening of the water control valve 16 and the water adding time to ensure a suitable ratio of flour to water.

[0039] In any of the above solutions, preferably, the two second lifting drive mechanisms are in a synchronous lifting motion state when working.

[0040] In any of the above schemes, it is preferred that the second lifting drive mechanism includes a vertically arranged second lifting electric cylinder 18, the bottom of the cylinder barrel of the second lifting electric cylinder 18 is fixed on the ground, and the upper part of the piston rod of the second lifting electric cylinder 18 is fixedly connected to the expansion disk 6 at the corresponding position.

[0041] The second lifting drive mechanism relies on the synchronous remote control of each second lifting electric cylinder 18 to ensure the stability of the lifting movement when realizing the lifting control, and effectively ensures that it can drive the expansion plate 6 on the top and the lifting control of the entire upper inverted barrel 2.

[0042] Embodiment 2: The difference between this embodiment and embodiment 1 is that:

[0043] It also includes the following technical features:

[0044] In any of the above solutions, preferably, drainage pipes 19 with valves are installed on both sides of the bottom of the lower supporting bucket 1 respectively.

[0045] By opening the drainage pipe 19, the remaining water can be quickly discharged to the outside after the cleaning process inside the lower support barrel 1 is completed and collected by the collection device.

[0046] In any of the above schemes, it is preferred that a plurality of water flow holes 20 are arranged on the lower outer wall of the hollow stirring shaft 11 from top to bottom, and each of the water flow holes 20 is connected to the inner cavity of the hollow stirring shaft 11 and discharges water to the outside during operation.

[0047] The water entering the hollow stirring shaft 11 can quickly flow into the flour through the water flow holes 20 at different heights, thereby ensuring that the water is quickly mixed with the flour, ensuring the mixing efficiency and effect when the flour and water are subsequently stirred.

[0048] Specific working principle: the lower supporting barrel 1 is located at the bottom as the main supporting structure, and the upper inverted barrel 2 is inserted above it to form an inner cavity for mixing flour and water through the cooperation of the lower supporting barrel 1 and the upper inverted barrel 2.

[0049] When it is necessary to control the feeding into the inner cavity, an appropriate amount of flour is fed into the inner cavity through the feeding pipe opening 3 .

[0050] At the same time, the first lifting drive mechanism and the second lifting drive mechanism are controlled to cooperate with each other so as to achieve the docking and pressing of the lower supporting bucket 1 and the upper inverted bucket 2 to ensure the sealing effect inside.

[0051] One seal is achieved by inserting and fitting the outer wall of the upper inverted barrel 2 with the inner wall of the lower supporting barrel 1, and two seals are achieved by clamping the jacket cavity 5, thereby achieving the purpose of improving the sealing effect. After the feeding is completed, the driving member is started. When the driving member starts to operate, it can drive the stirring mechanism to drive the flour and water inside to mix and stir quickly into a mass. Specifically, as an execution structure, the stirring mechanism mainly relies on the linkage of the stirring motor 7 to drive the hollow stirring shaft 11 to rotate on a fixed axis during operation. When the hollow stirring shaft 11 rotates, it will drive the rectangular scraper frame 12 fixedly connected to its outer wall to scrape the inner wall of the cavity of the upper inverted barrel 2, thereby ensuring the rapid scraping of the dough blocks adhered to the inner wall of the cavity of the upper inverted barrel 2; in addition, during the operation of the hollow stirring shaft 11, the rotating stirring of the horizontal stirring rod 13 can achieve rapid stirring of the flour inside the cavity of the upper inverted barrel 2, thereby improving the stirring effect.

[0052] From the above, it can be seen that the flour mixer as a whole adopts a structure that is coordinated and detachable up and down, which can ensure the internal sealing and leakage-proof effect when the flour and water are mixed and stirred. At the same time, after the flour mixing and stirring is completed, it can be separated up and down to expose the mixed dough, which is convenient for picking up the dough outside.

[0053] When mixing flour, the flour mixer can rely on the rectangular scraper frames 12 on both sides to quickly scrape the dough blocks adhered to the inner wall of the inner cavity, thereby reducing the probability of the side wall adhering to the surface of the dough; during the mixing process, the upper outer spiral tube 14 and the conveying pipe 17 can be used to add external water sources to different positions of the flour as needed, thereby better ensuring that the water is quickly and fully mixed, and improving the efficiency and effect of mixing.

[0054] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model. For technicians in this technical field, any replacement improvements or changes made to the implementation methods of the utility model fall within the protection scope of the utility model.
