Description

Technical Field

[0001] The utility model relates to the technical field of beer brewing and processing, in particular to a multifunctional driving mechanism of a wheat screening machine for beer brewing. Background Art

[0002] Beer is a fermented wine made from malt and water with hops and fermented with yeast. It contains carbon dioxide and can form foam, including non-alcoholic beer. Before brewing, wheat usually needs to be screened to determine the quality and flavor of the beer. Therefore, a wheat screening machine is needed. The wheat screening machine is an agricultural machinery used to screen wheat and remove impurities. Its working principle is based on the principles of vibration and screening. Impurities are separated from wheat through the combination of a vibrator and a screen.

[0003] At present, the driving mechanism of the existing wheat screening machine for beer brewing usually generates vibration through a vibration motor to make the screen shake and filter the wheat inside. Therefore, the vibration motor will generate violent noise, causing noise pollution, and will also cause discomfort to the operator, greatly reducing the comfort of use. In addition, the existing wheat screening machine for beer brewing is not equipped with a wheat stirring device. Therefore, when the wheat enters the screening bin for screening, it is easy to accumulate, which reduces the screening efficiency, thereby reducing the practicality and work efficiency of the wheat screening machine for beer brewing.

[0006] According to the above technical solution, the eccentric shaft is driven to rotate by the motor, and the eccentric shaft drives the linkage rod to pull the screening bin to shake to achieve the screening effect, avoiding the violent noise generated by the transmission vibration motor. At the same time, it can also drive the blower mechanism to rotate, so that the wheat inside the screening bin is stirred by wind, avoiding the accumulation of wheat, and improving the efficiency of wheat screening.

[0009] Furthermore, the diameter of the pulley a is smaller than that of the pulley b, and the diameter of the pulley c is larger than that of the pulley d.

[0010] According to the above technical solution, by making the diameter of pulley a smaller than that of pulley b, the violent shaking of the screening bin can be reduced, thereby improving the accuracy and safety of screening. By making the diameter of pulley c larger than that of pulley d, the rotation speed of the impeller can be increased, thereby ensuring the wind force.

[0011] Furthermore, the guide port is rectangular, and an inclined surface is provided inside the guide port, and the inclination angle of the inclined surface gradually decreases toward the opening of the guide port.

[0012] According to the above technical solution, the accuracy of the wind force can be improved by the inclined surface, so that it can be blown and stirred directly into the screening bin.

DETAILED DESCRIPTION

[0023] Reference Figure 1-6 , the embodiment is a multifunctional driving mechanism of a wheat screening machine for beer brewing, which is composed of a mounting frame 1, a screening bin 2, a feed bin 3 and the like. The mounting frame 1 is used for mounting the screening bin 2 and the feed bin 3 and the like. The screening bin 2 is used for screening wheat. The feed bin 3 is used for pouring wheat. The feed bin 3 is located above one side of the screening bin 2. Two rotating shafts a 4 are respectively installed at two ends of the screening bin 2. The rotating shaft a 4 is rotationally connected with a connecting rod 5. The connecting rod 5 is rotationally connected with the mounting frame 1 at an end away from the rotating shaft a 4, so as to facilitate the screening bin 2 to shake. A driving mechanism is installed on the mounting frame 1. The driving mechanism comprises a motor 6. A pulley a 7 is installed at an output end of the motor 6. The pulley a 7 is transmissionally connected with a belt a 8 on a surface. An end of the belt a 8 away from the pulley a 7 is transmissionally connected with a pulley b 9. A transmission shaft a 10 is installed at one end of the pulley b 9. A fixed seat 11 is fixedly installed on one side of the mounting frame 1. The transmission shaft a 10 penetrates through a bearing 12 in a middle part of the fixed seat 11 at an end away from the pulley b 9 and is rotationally connected with the fixed seat 11. An eccentric shaft 13 is fixedly installed at an end of the transmission shaft a 10 away from the pulley b 9. The eccentric shaft 13 is rotationally connected with a linkage rod 14. A rotating shaft b 15 is fixedly installed at a bottom of the screening bin 2. An end of the linkage rod 14 away from the eccentric shaft 13 is rotationally connected with the rotating shaft b 15. A pulley c 16 is fixedly installed at one end of the pulley a 7. The pulley c 16 is coaxial with the pulley a 7 and the output end of the motor 6. The pulley c 16 is transmissionally connected with a belt b 17. An end of the belt b 17 away from the pulley c 16 is transmissionally connected with a pulley d 18. The pulley d 18 is transmissionally connected with a blowing mechanism. The blowing mechanism blows and stirs the wheat in the screening bin 2 when working, so as to avoid the wheat from piling up.

[0024] Further, the blowing mechanism comprises a mounting cover 19. An impeller 20 is rotationally installed inside the mounting cover 19. A transmission shaft b 21 is fixedly installed at one end of the pulley d 18. The transmission shaft b 21 is transmissionally connected with the impeller 20 at an end away from the pulley d 18. The mounting cover 19 is hollow inside and is continuously connected with an air outlet pipe 22 on a surface. An air inlet 23 is fixedly installed at a bottom of the feed bin 3. An end of the air outlet pipe 22 away from the mounting cover 19 is communicated with the air inlet 23. The air inlet 23 is hollow inside and is provided with an opening at one end. The opening is directed to an inside of the screening bin 2.

[0025] Furthermore, the diameter of pulley a7 is smaller than that of pulley b9, and the diameter of pulley c16 is larger than that of pulley d18.

[0026] Furthermore, the guide port is rectangular, and an inclined surface 24 is provided inside the guide port. The inclination angle of the inclined surface 24 gradually decreases toward the opening of the air guide port 23 , so that the air flow blows into the screening bin 2 .

[0027] Furthermore, the air outlet pipe 22 is made of soft material, which improves plasticity.

[0028] The working principle of this embodiment is as follows: when working, the motor 6 drives the pulley a7 and the pulley c16 to rotate, thereby driving the pulley b9 and the pulley d18 to rotate through the belt a8 and the belt b17 respectively. When the pulley b9 rotates, the eccentric shaft 13 is driven to rotate through the transmission shaft a10, and the linkage rod 14 is pulled by the eccentricity of the eccentric shaft 13. At this time, the linkage rod 14 pulls the screening bin 2 through the rotating shaft a4, and the screening bin 2 is rotatably connected to the rotating shaft a4 through the connecting rod 5, so that the screening bin 2 swings back and forth to screen the wheat, avoiding the noise generated by the traditional vibration motor; at the same time, when the pulley d18 rotates, it drives the impeller 20 to rotate through the transmission shaft b21, and when the impeller 20 rotates, it generates wind that is discharged into the guide port through the air outlet pipe 22, and finally blows and stirs the wheat on the surface of the screening bin 2 through the air guide port 23, avoiding the accumulation of wheat and improving the screening efficiency.
