[0030] Example 1
[0031] Reference Figures 1-4 As one embodiment of this utility model, a trough-type mixer with anti-sticking function is provided, which can effectively and promptly scrape off materials adhering to the bottom of the inner wall of the trough. It includes a mixing unit 100 and an anti-sticking unit 200.
[0032] The mixing unit 100 includes a tank 101 and two housings, 102 and 103, located on either side of the tank 101. A stirring shaft 104 is rotatably mounted inside the tank 101. A rotary drive assembly 105 is housed inside the housing 103, with its output end connected to the stirring shaft 104. The tank 101 serves as the basic space for material mixing. The housings 102 and 103 not only provide protection but also offer installation positions for key components. The rotary drive assembly 105 inside the housing 103 is the power source for the rotation of the stirring shaft 104. A fixedly mounted motor 105a serves as the core power unit, with its output drive shaft 105b connected to the stirring shaft 104 extending into the housing 103. After the motor 105a starts, it precisely transmits power to the stirring shaft 104 via the drive shaft 105b, causing the stirring shaft 104 to rotate stably within the tank 101, thus performing initial mixing of the materials.
[0033] The anti-sticking unit 200 includes a transmission component 201 disposed at the output end of the rotary drive component 105 and a plurality of scrapers 203 disposed inside the tank 101. The working surface of the scrapers 203 maintains sliding contact with the bottom curved surface of the inner wall of the tank 101. The transmission component 201 is used to drive the scrapers 203 to reciprocate horizontally. The transmission component 201 disposed at the output end of the rotary drive component 105 works in cooperation with the plurality of scrapers 203 inside the tank 101. The working surface of the scrapers 203 is in close contact with the bottom curved surface of the inner wall of the tank 101. Driven by the transmission component 201, the scrapers 203 can achieve reciprocating horizontal displacement, promptly scraping off the material adhering to the bottom of the inner wall of the tank 101, ensuring the uniformity of material mixing.
[0034] The rotary drive assembly 105 includes a motor 105a fixedly installed in the housing 103. The output end of the motor 105a is fixedly connected to a drive shaft 105b. The stirring shaft 104 extends into the interior of the housing 103 and is connected at one end to the drive shaft 105b.
[0035] In use, the materials to be mixed are first poured into the tank 101, and then the motor 105a in the casing 103 is started. After the motor 105a starts running, the drive shaft 105b drives the stirring shaft 104 to start rotating, stirring the materials in the tank 101. At the same time, the transmission component 201 uses the power output from the rotation drive component 105 to drive the scraper 203 to make reciprocating horizontal movements in the tank 101. Under the dual action of continuous stirring by the stirring shaft 104 and continuous scraping of the wall by the scraper 203, the materials are fully mixed in the tank 101.
[0036] This embodiment effectively avoids the adhesion and accumulation of materials on the bottom of the inner wall of the tank 101 by cooperating with the stirring shaft 104 and the scraper 203, which significantly improves the uniformity of material mixing, simplifies the mixing process, reduces the cleaning work caused by material sticking to the wall, improves mixing efficiency, and reduces maintenance costs.
[0037] Example 2
[0038] Reference Figures 1-4 This is the second embodiment of the present invention. Unlike the previous embodiment, the transmission assembly 201 includes a fixed seat 201a fixedly installed on the outer wall of the tank 101. A synchronous shaft 201b rotatably passes through the fixed seat 201a. One end of the synchronous shaft 201b is fixedly connected to a bevel gear 201c. A second bevel gear 201d is fixedly connected to the stirring shaft 104. The first bevel gear 201c and the second bevel gear 201d are meshed together. The other end of the synchronous shaft 201b is fixedly connected to a turntable 201e. An eccentric shaft 201f is fixedly connected to the bottom of the turntable 201e.
[0039] The interior of the tank 101 is horizontally equipped with crossbars 202, two of which are symmetrically arranged. Each scraper 203 is vertically fixed to the crossbar 202 at equal intervals. One end of each crossbar 202 slides through the tank 101 and is fixedly connected to a push rod 204. The push rod 204 is rotatably connected to the eccentric shaft 201f. Regarding the transmission assembly 201, a fixed base 201a, fixedly installed on the outer wall of the tank 101, provides a stable rotation fulcrum for the synchronous shaft 201b. A bevel gear 201c at one end of the synchronous shaft 201b meshes with a bevel gear 201d on the stirring shaft 104, forming a highly efficient transmission structure. When the stirring shaft 104 rotates, power is transmitted to the synchronous shaft 201b through the meshing transmission of bevel gear 201c and bevel gear 201d. The turntable 201e at the other end of the synchronous shaft 201b rotates accordingly. During the rotation, the eccentric shaft 201f at the bottom of the turntable 201e provides the driving force for the reciprocating motion of the push rod 204. The two symmetrical crossbars 202 inside the tank 101 serve as mounting carriers for the scrapers 203, fixing multiple scrapers 203 vertically at equal intervals, so that the scrapers 203 can evenly cover the bottom area of the inner wall of the tank 101. The push rod 204 at one end of the crossbar 202 is rotatably connected to the eccentric shaft 201f, thereby converting the circular motion of the eccentric shaft 201f into the reciprocating horizontal motion of the crossbar 202 and the scrapers 203.
[0040] Connecting rings 106 are provided between the two ends of the tank 101 and the first chassis 102 and the second chassis 103, and the connecting rings 106 are fixedly connected to the tank 101.
[0041] One end of a connecting ring 106 rotatably penetrates the wall of housing 102 and extends into the interior of housing 102. One end of the other connecting ring 106 is rotatably connected to housing 103, and the stirring shaft 104 passes through the connecting ring 106. The connecting rings 106 at both ends not only ensure a stable connection between the tank 101 and housings 102 and 103, but also guarantee the rotational flexibility of the tank 101. The fact that one end of a connecting ring 106 rotatably penetrates housing 102 and extends into the interior, while the other connecting ring 106 is rotatably connected to housing 103, and the stirring shaft 104 passes through the connecting ring 106 ensures that the stirring shaft 104 is not disturbed during rotation.
[0042] It also includes a flipping assembly 107 disposed inside the chassis 102. The flipping assembly 107 includes a worm gear 107a, which is fixedly installed on one end of the connecting ring 106 located inside the chassis 102. A worm 107b is rotatably installed on the inner wall of the chassis 102, and the worm 107b is meshed with the worm gear 107a.
[0043] A second motor 107c is fixedly installed inside the casing 102. The second motor 107c is used to drive the worm gear 107b to rotate. When unloading is required, the second motor 107c starts, and through the transmission between the worm gear 107b and the worm wheel 107a, it drives the connecting ring 106 to rotate, thereby realizing the flipping of the tank 101.
[0044] The material is placed into the tank 101. Motor 105a in the second housing 103 is started. Motor 105a drives the stirring shaft 104 to rotate. The stirring shaft 104, through bevel gear transmission, causes the synchronous shaft 201b to rotate. The synchronous shaft 201b drives the turntable 201e and the eccentric shaft 201f to rotate. The eccentric shaft 201f pushes the push rod 204, causing the crossbar 202 and scraper 203 to reciprocate horizontally within the tank 101, mixing the material while preventing it from sticking to the walls. After mixing is complete, motor 107c in the first housing 102 is started. Motor 107c drives the worm gear 107b to rotate. The worm gear 107b drives the worm wheel 107a to rotate, thereby rotating the connecting ring 106 and causing the tank 101 to flip, smoothly discharging the mixed material.
[0045] This embodiment optimizes the transmission component 201, making the movement of the scraper 203 more stable and efficient, and further enhancing the anti-sticking effect. The connection ring 106 and the flipping component 107 not only ensure the stability of the equipment operation, but also realize convenient unloading, greatly improving production efficiency, reducing unloading time and manpower input, while ensuring more thorough and uniform mixing of materials, and improving product quality.
[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
