Description

Technical Field

[0001] This utility model relates to the technical field of rice processing equipment, and in particular to a dust-free rice processing gravity destoner. Background Technology

[0002] Removing impurities such as stones from rice is a crucial step in rice processing. This not only affects the quality and taste of the rice but also directly impacts consumer health and safety. Traditional rice destoners primarily utilize the difference in suspension velocity and density between rice grains and stones, using mechanical airflow to separate the stones from the rice grains. However, these traditional destoners have revealed numerous problems in practical applications.

[0003] Dust pollution is a particularly prominent issue. The destoning process generates a large amount of dust, which not only permeates the working environment, posing a serious threat to the health of operators (long-term inhalation can lead to occupational diseases such as pneumoconiosis), but also pollutes the surrounding environment. Furthermore, dust accumulation inside the equipment can affect its normal operation and reduce its lifespan.

[0004] Furthermore, the destoning effect of traditional destoning machines is not entirely satisfactory. They often cannot be flexibly adjusted according to different material characteristics and processing requirements. In some special cases, such as when the stone content is high or when the rice variety is different, the destoning efficiency and precision will decrease significantly, resulting in some stone residue and affecting the quality of the rice. Moreover, the vibration mode of the screen plate of traditional destoning machines is relatively simple, and the vibration amplitude and tilt angle are generally fixed and cannot be adjusted, which cannot adapt to diverse processing needs and further limits the improvement of destoning effect.

[0005] Therefore, this utility model proposes a dust-free rice processing gravity destoner to solve the above problems.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

A groove is provided on the turntable 221, and a slider 222 is slidably installed in the groove.

A rotating block 224 is fixedly installed outside the groove to facilitate the adjustment of the distance between the slider 222 and the first output shaft of the dual-axis motor 22, thereby adjusting the vibration amplitude of the screen plate 2. In order to stably limit the slider 222 after the position is adjusted and prevent it from sliding in the groove, a limiting screw is threaded on the rotating block 224. A knob is fixedly installed at one end of the limiting screw. Multiple screw holes are opened on the outer periphery of the rotating block 224 based on the screw 223 as the center. The end of the limiting screw away from the knob is threaded into the corresponding screw hole.

In order to facilitate the operator to control the rotation of the screw rod 242, an adjusting wheel is fixedly sleeved on the screw rod 242.

[0049] The strip box 3 is fixedly installed on one side of the housing 1. The bottom of the hollow plate 32 has multiple through holes and is fixedly installed on the top inner wall of the housing 1. The strip box 3 and the hollow plate 32 are connected by the air duct 31. The side of the strip box 3 away from the housing 1 has a rectangular opening, and the sealing plate 302 is slidably installed in the rectangular opening. The air outlet duct 33 is fixedly installed at the bottom of the strip box 3 and is connected to the strip box 3. The second output shaft of the dual-axis motor 22 extends into the air outlet duct 33 and is fixedly fitted with fan blades 34. The power generated by the dual-axis motor 22 when it is working can be used to cooperate with the fan blades 34 and the air outlet duct 33 to realize the dust extraction operation in the housing 1. In order to intercept and temporarily store the dust sucked into the strip box 3, a filter plate 301 is fixedly installed in the strip box 3 at an incline.

[0050] Specifically, in order to effectively prevent large stones from entering the shell 1, and to divert the rice poured into the feed hopper 11 to a certain extent, so that it can be evenly dispersed and fall onto the screen plate 2, thereby effectively avoiding the phenomenon of rice accumulation in local positions on the screen plate 2, limit strips are fixedly installed on the inner walls of both sides of the feed inlet, and a grate plate 111 that contacts the top side of the two limit strips is snapped into the feed inlet.

[0051] Specifically, in order to prevent rice from falling between the sieve plate 2 and the inner wall of one side of the shell 1, a guide plate 12 is fixedly installed on the inner wall of one side of the shell 1, and the top side of the guide plate 12 is inclined and located above the sieve plate 2.

[0052] Specifically, to facilitate the installation and removal of the sealing plate 302 by operators, the front side of the sealing plate 302 extends to the front side of the strip box 3 and is fixedly installed with a handle.

[0053] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0054] Working principle: First, connect the power supply. When it is necessary to adjust the vibration amplitude of the screen plate 2, the operator can rotate the rotating block 224. The rotating block 224 drives the lead screw 223 to rotate. Since the slider 222 is threadedly connected to the lead screw 223, the slider 222 can move in the groove during the rotation of the lead screw 223. This allows for adjustment of the distance between the slider 222 and the first output shaft of the dual-axis motor 22, thereby adjusting the vibration amplitude of the screen plate 2 and enhancing the adaptability and flexibility of the equipment. After the slider 222 position is adjusted, the rotating block 224 can be limited by the limiting lead screw. Then, the dual-axis motor 22 is started, and its first output shaft drives the turntable 221 to rotate. With the cooperation of the support rod 23 and the two rotating pins, the front guide block 21 can be controlled to drive the screen plate 2 to reciprocate. At the same time, with the cooperation of the rear guide block 21 and the guide pin 241, the screen plate 2 can maintain stable reciprocating motion.

[0055] When the tilt angle of the screen plate 2 needs to be adjusted, the operator can rotate the adjusting wheel, which drives the screw 242 to rotate. Since the lifting block 24 is threadedly connected to the screw 242, the lifting block 24 can move on the screw 242 during the rotation of the screw 242. The lifting block 24 adjusts the tilt angle of the screen plate 2 through the guide pin 241 and the guide groove, thus optimizing the stone removal effect.

[0056] While the dual-shaft motor 22 is working, its second output shaft drives the fan blade 34 to rotate. The rotation of the fan blade 34 generates suction. Through the combined action of the air outlet duct 33, the strip box 3, the air duct 31 and the hollow plate 32, the dust generated during the screening process inside the shell 1 can be sucked into the strip box 3 through multiple through holes. The filter plate 301 inside the strip box 3 intercepts and temporarily stores the sucked-in dust, thereby realizing the dust removal operation inside the shell 1 and maintaining the cleanliness and efficient operation of the equipment.

[0057] When it is necessary to clean the dust inside the bar box 3, the operator can pull the handle, which will move the sealing plate 302. The sealing plate 302 can be removed from the bar box 3, and the dust inside the bar box 3 can be cleaned. The operation is simple.
