[0032] The utility model discloses a working principle: material is entered into material cylinder 2 from material basin 1 through downcomer 53, when material enters a certain amount, motor 4 drives agitator to rotate, and material is pushed to the discharge end in the stirring process, and valve rod subassembly 7 initial state closes discharge passage 611, and when discharging, valve rod subassembly 7 opens discharge passage 611, and the material in material cylinder 2 is discharged through discharge passage 611.

[0033] In practical application, the refrigeration subassembly includes condenser and compressor, which is used for conveying refrigerant to evaporimeter 3, and evaporimeter 3 transmits cold quantity to material cylinder 2, and since it is prior art, detailed description is not given.

[0034] Further, the first end of the connecting seat 5 is provided with a connecting column 51 for connecting with the motor 4, the second end of the connecting seat 5 is provided with a connecting plate 52 for connecting with the support 21 of the barrel 2, the connecting seat 5 is transversely provided with a through hole 54 penetrating the connecting column 51 and the connecting plate 52, the output shaft of the motor 4 penetrates the through hole 54 and is connected with the stirrer; the discharging port 57 of the discharging pipe 53 is arranged on the connecting plate 52, and the central axis of the discharging port 57 is not in the same vertical plane as the central axis of the through hole 54. In this way, during assembly, the connecting column 51 is connected with the motor 4, the connecting plate 52 is connected with the support 21 of the barrel 2, the output shaft of the motor 4 penetrates the through hole 54 and extends into the barrel 2 to be connected with the transmission shaft of the stirrer. It should be noted that, since the central axis of the discharging port 57 is not in the same vertical plane as the central axis of the through hole 54 (for example, as shown in a and b), when the material is discharged through the discharging port 57, the material will not interfere with the output shaft of the motor 4 or the connecting shaft of the stirrer, that is, the material will not form a material accumulation on the output shaft of the motor 4 or the connecting shaft of the stirrer, but will directly fall into the barrel 2, thereby making the discharging effect and efficiency more ideal. Figure 4

[0035] In actual application, the output end of the motor 4 is connected with a speed reducer for driving connection with the stirrer, which is prior art and will not be described in detail.

[0036] Further, the connecting column 51 is provided with a sensor mounting hole 55 communicating with the through hole 54, and a sensor for detecting the rotating speed of the motor 4 is mounted in the sensor mounting hole 55. In this way, the rotating speed of the motor shaft can be accurately detected by the sensor.

[0037] In actual application, the sensor is integrated on the connecting column 51, which is more convenient to assemble and more accurate to detect, compared with the conventional technology of mounting the sensor on the motor housing.

[0038] Further, the through hole 54 is provided with a limiting ring 56 and a sealing ring mounting groove 58 at one end close to the connecting plate 52, and a sealing ring for sealing the output shaft of the motor 4 is mounted in the sealing ring mounting groove 58. In this way, the limiting ring 56 can limit the assembly position of the motor 4, so that the assembly position is more accurate; in order to improve the rotation of the output shaft of the motor 4, a bearing is assembled on the limiting ring 6; by mounting the sealing ring in the sealing ring mounting groove 8, the sealing ring can form a seal with the outer wall of the output shaft of the motor 4 after assembly, so as to prevent the material in the barrel 2 from overflowing into the through hole 54 and affecting the working performance of the output shaft of the motor 4.

[0039] ​Furthermore, the inner side of the discharge valve 6 is fixedly connected to the support 22 of the material cylinder 2, and the inner side of the discharge valve 6 is formed with an annular groove 61 corresponding to the material cylinder 2. The inner wall of the annular groove 61 is provided with a shaft hole 62 and a discharge port 63. The discharge port 63 is connected to the discharge channel 611, and the discharge channel 611 is provided with a discharge port 610. With this configuration, during assembly, the annular groove 61 is fitted onto the outer wall of the material cylinder 2. After assembly, the inner wall of the opening of the annular groove 61 is sealed to the outer wall of the material cylinder 2 to prevent material overflow. When the agitator in the evaporator 3 rotates, it drives the material to push towards the discharge port 63. The material enters the discharge channel 611 through the discharge port 63 and is discharged through the discharge port 610. One end of the drive shaft of the agitator is connected to the output end of the motor 4, and the other end is rotatably located in the shaft hole 62. The agitator is existing technology and will not be described in detail.

[0040] Furthermore, the inner wall of the annular groove 61 is provided with an arc-shaped guide groove 64 that mates with the discharge port 63. The arc-shaped guide groove 64 is inclined, with its higher end connected to the inner wall surface of the annular groove 61 and its lower end connected to the discharge port 63. The discharge port 63 is provided with a baffle 65. This arrangement, as... Figure 5 As shown, when the agitator is working, it drives the material to rotate counterclockwise relative to the inner wall of the annular groove 61. When the moving material comes into contact with the inner wall of the annular groove 61, the material is guided to the discharge port 63 along the inclined surface of the arc-shaped guide groove 64 under the thrust of the spiral blades. After the material is blocked by the baffle 65, the material enters the discharge channel 611 from the discharge port 63.

[0041] Furthermore, such as Figure 5 and 8 As shown, there are two discharge ports 63 arranged side by side, with a partition between them. This arrangement improves material feeding efficiency while reducing the pressure during material feeding, preventing material from clumping or forming large particles, and avoiding excessive pressure during feeding that could cause splashing when receiving the material.

[0042] Furthermore, the valve stem assembly 7 includes a handle 71, a connecting shaft 72, and a valve stem 73.

The connecting shaft 72 is hinged to the outside of the discharge valve 6. With this configuration, in the initial state, the valve stem 73 is located in the discharge channel 611, and the discharge channel 611 is in a closed state. When it is necessary to open the discharge channel 611, pulling the handle 71 downward will cause the valve stem 73 to move upward, thereby opening the discharge channel 611. When closing the discharge channel 611, pushing the handle 71 upward will cause the valve stem 73 to move downward, making operation convenient.

[0043] Further, two sides of the upper opening 69 are provided with mounting ears 68, a connecting shaft 72 is hingedly connected between the two mounting ears 68 through a rotating shaft, a limiting block one 67 is arranged on the connecting shaft 72, a limiting block two 74 is arranged on the outer wall of the discharge channel 611, and the limiting block one 67 and the limiting block two 74 are arranged in correspondence. In this way, when assembling, the valve rod 73 is inserted into the discharge channel 611 through the upper opening 69, and then the rotating shaft passes through the connecting shaft 72 and the two mounting ears 68 to form a hinge connection, so that the assembly is convenient; when the handle 71 is pulled downward to a certain position, the limiting block one 67 abuts against the limiting block two 74 to form a limit, so as to limit the stroke of the valve rod 73 in the discharge channel 611.

[0044] Further, the valve rod 73 comprises a connecting portion 76 and a sealing portion 77, the connecting shaft 72 is clampedly connected with the connecting portion 76, the connecting portion 76 is slidingly arranged at the upper portion of the discharge channel 611, and the sealing portion 77 is slidingly arranged at the lower portion of the discharge channel 611, and the sealing portion 77 is used for opening or closing the discharge channel 611. In this way, the discharge channel 611 is opened or closed through the sealing portion 77.

[0045] Further, the sealing portion 27 is a sealing ring fixedly sleeved on the lower portion of the valve rod 73, and the upper and lower ends of the sealing ring are limited by a limiting step arranged at the lower end of the valve rod 73 through the connecting portion 76. After assembly, the sealing ring is sealed with the inner wall of the discharge channel 611.

[0046] Further, a slot hole 78 is arranged on the connecting portion 76, a fixed rod 79 is fixedly arranged in the slot hole 78, a fixed clamp 75 is fixedly arranged on the connecting shaft 72, and the fixed clamp 75 extends into the slot hole 78 and is clampedly connected with the fixed rod 79. In this way, the fixed clamp 75 is arranged at a certain angle downward relative to the handle 71, and the fixed clamp 75 and the handle 71 form a lever structure. When the handle 71 is pulled downward, the fixed clamp 75 drives the valve rod 73 to act upward; when the handle 71 is pushed upward, the fixed clamp 75 drives the valve rod 73 to act downward.
