[0036] In the description of this patent, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be fixedly connected or set, or it can be detachably connected or set, or connected or set in one piece. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.
[0037] Reference Figure 1-5A single-arm resin sand mixer comprises: a body 2, which is cylindrical and has a conveying space for mixing and processing inside; a discharge port 6, which is connected to the bottom of the surface of the body 2 and communicates with the conveying space inside the body 2; a docking part 7, which is installed on the outer surface of the discharge port 6 and has a screening mechanism for improving the discharge quality inside the body 2, so that the discharged material can be filtered and screened by the screening mechanism, thereby improving the discharge quality; a movable anti-leakage mechanism is installed inside the discharge port 6, and the anti-leakage mechanism can effectively prevent the material in the body 2 from leaking out, and a limiting mechanism linked to the anti-leakage mechanism is installed above the surface of the docking part 7, so that the anti-leakage mechanism can be fixed to a certain limit by the limiting mechanism, so as to avoid the anti-leakage mechanism from easily moving and affecting the anti-leakage sealing effect.
[0038] Reference Figure 1 and Figure 3 A machine chamber 5 is installed on the surface of the machine body 2, and a feed hopper 4 connected with the machine chamber 5 and the machine body 2 is installed on the upper part of the machine chamber 5. A protective mechanism is installed inside the feed hopper 4, which can protect the high-temperature hot air and related harmful gases generated by the sand mixer during operation to reduce the impact on personnel.
[0039] Reference Figure 1 and Figure 3 The protective mechanism includes: a fixed plate 11, a first elastic member 12 and two baffles 13; the fixed plate 11 is installed inside the feed hopper 4, and the two baffles 13 are rotatably connected to the inside of the machine chamber 5 through hinges, and the first elastic members 12 are correspondingly connected between the fixed plate 11 and the baffles 13. When the raw material is added into the machine body 2 through the feed hopper 4, the baffle 13 can be pressed downward by the weight of the raw material to open the feed hopper 4, and the baffle 13 can stretch the first elastic member 12 and flip it. After the raw material is added, the first elastic member 12 can restore its elasticity to drive the baffle 13 to reset and close the feed hopper 4.
[0040] Specifically, the baffle 13 is constructed with two position states: open and closed. When the baffle 13 is closed, it seals the feed hopper 4, so that the baffle 13 can fit better with the lower part of the feed hopper 4 when closed, thereby reducing the leakage of hot air or harmful gases and improving the sealing and protection effects.
[0041] Reference Figure 2 , Figure 4 and Figure 5The screening mechanism includes: a screening member 16 and a second elastic member 15; the screening member 16 is located at the lower part of the discharge port 6 and is movably arranged inside the docking portion 7, and the second elastic member 15 is vertically connected between the screening member 16 and the docking portion 7. When the material in the body 2 is discharged, the mixed material can be screened and filtered by the screening member 16 installed inside the docking portion 7 to avoid the discharged material being of different sizes or the existence of unmixed materials, thereby improving the quality of the material discharged from the body 2, and when the movable member 8 is turned over, the screening member 16 can be pushed to move, so that the material on the surface of the screening member 16 can be more effectively discharged downward to avoid blockage. Specifically, the cross-sectional area of the screening member 16 is larger than the cross-sectional area of the discharge port 6. In this way, the screening member 16 can more effectively perform the filtering and screening effect to avoid the material being directly discharged without being processed by the screening member 16 and affecting the quality.
[0042] Reference Figure 2 , Figure 4 and Figure 5 The leakage prevention mechanism includes: a rotating member 14, a movable member 8 and a connecting member 9; the rotating member 14 is connected to the inside of the discharge port 6 and partially penetrates to the outside of the discharge port 6, the movable member 8 is installed on the surface of the rotating member 14 located inside the discharge port 6 and fits with the inside of the discharge port 6, and the connecting member 9 is installed at one end of the rotating member 14 located outside the discharge port 6. The movable member 8 fits with the inside of the discharge port 6 so that the discharge port 6 can be better sealed, thereby preventing material from leaking out of the machine body 2 during operation. At the same time, when discharging, the movable member 8 can rotate through the rotating member 14, so that the material in the machine body 2 can be discharged in an orderly manner.
[0043] Refer to the figure Figure 2 and Figure 5 The limiting mechanism includes: a bracket 17, a third elastic member 18 and a limiting member 10; the bracket 17 is installed on the upper part of the docking portion 7, the limiting member 10 is meshed with the connecting member 9 and slidably connected to the inner side of the bracket 17, and the third elastic member 18 is installed between the limiting member 10 and the bracket 17. When the material in the sand mixer is discharged, the limiting member 10 can be pressed downward so that the limiting member 10 can slide downward in the bracket 17 and compress the third elastic member 18 to release the limit of the rotating member 14, so that the staff can rotate the connecting member 9, thereby driving the movable member 8 to flip to open the discharge port 6. On the contrary, when the mixing and stirring process is carried out, the movable member 8 can be limited and fixed by the limiting mechanism to prevent the movable member 8 from being affected and vibrating and loosening, thereby improving stability. Specifically, the limiting method of the limiting member 10 and the connecting member 9 can adopt the meshing of gear racks to fix the gears, and can also adopt a form with certain protrusions and grooves matching, so that the limiting member 10 and the connecting member 9 can be matched and fixed.
[0044] Reference Figure 1 and Figure 3 A base 1 is installed on the lower side of the body 2 away from the discharge port 6, and a control cabinet 3 is provided on the surface of the base 1 to connect and control the equipment through the control cabinet 3. A drive motor 20 is installed at one end of the body 2, and the output end of the drive motor 20 is connected to the stirring and conveying mechanism 19 installed inside the body 2, so that the drive motor 20 can be started after the raw materials are added into the body 2. After the drive motor 20 works, it can drive the stirring and conveying mechanism 19 to rotate, thereby performing a certain stirring, mixing and conveying process on the raw materials.
[0045] Working principle: When using the utility model, the raw materials are added into the machine body 2 through the feed hopper 4 for mixing. At this time, the weight of the raw materials can press the baffle 13 downward to open the feed hopper 4, and the baffle 13 can stretch the first elastic member 12 and turn it over. Then, after the raw materials are added, the first elastic member 12 can restore its elasticity to drive the baffle 13 to reset and close the feed hopper 4 to prevent the internal hot air and some harmful gases from leaking out during the operation of the sand mixer and affecting the staff, thereby improving the protection. At this time, the driving motor 20 works to drive the internal stirring and conveying mechanism 19 to operate for mixing and conveying processing. When performing the mixing and stirring process, the movable part 8 can be limited and fixed by the limiting mechanism to prevent the movable part 8 from being affected and vibrating and loosening, thereby improving stability. Then When the material in the sand mixer is to be discharged, the limiting member 10 can be pressed downward so that the limiting member 10 can slide downward in the bracket 17 and compress the third elastic member 18 to release the limit on the rotating member 14, so that the staff can rotate the connecting member 9, thereby driving the movable member 8 to flip to open the discharge port 6, so that the material in the machine body 2 can be discharged in an orderly manner and congestion can be avoided. At the same time, when the material in the machine body 2 is discharged, the mixed material can be screened and filtered by the screening member 16 installed inside the docking portion 7 to avoid the situation where the discharged material is of different sizes or cannot be mixed, thereby improving the quality of the material discharged from the machine body 2, and when the movable member 8 is flipped, it can push the screening member 16 to move, so that the material on the surface of the screening member 16 can be more effectively discharged downward to avoid blockage.
[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
