Description

Technical Field

[0001] The utility model belongs to the technical field of grain screening, and particularly relates to a grain screening device. Background Technique

[0002] Grain screening is a technology used in the process of grain processing. The main purpose is to grade and screen grains in order to remove impurities, separate grains of different sizes or varieties. Grains include rice, wheat, corn, millet, etc.;

[0003] In the existing grain screening, the grains are usually directly poured into the screening device for rotation all at once. However, sometimes, due to too much grain poured in at one time, the situation of grain blockage will occur, making the grains unable to flow into the screening machine normally. In severe cases, the device will be damaged. Therefore, we provide a grain screening device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a grain screening device. Through the stirring rod, the problem that sometimes, due to too much grain poured in at one time, the situation of grain blockage occurs, making the grains unable to flow into the screening machine normally is solved.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a grain screening device, including an anti-blocking mechanism and a storage box. The bottom of the anti-blocking mechanism is provided with a screening mechanism. The bottom of the storage box is fixedly connected with a screening box. The top of the screening box is fixedly connected with a fixed platform. The top of the fixed platform is fixedly connected with a motor. The bottom output end of the motor is fixedly connected with a rotating shaft. The front of the rotating shaft penetrates through the storage box and extends to the inside. The front of the rotating shaft is fixedly connected with a rotating disk. The front of the rotating disk is provided with a sliding groove. The inner wall of the sliding groove is slidably connected with a stirring rod. One end of the stirring rod away from the rotating disk is fixedly connected with a movable block. The outer surface of the stirring rod contacts a fixed disk. The stirring rod moves to stir the materials inside the storage box, preventing blockage and abnormal feeding.

[0007] Furthermore, the front of the fixed disk is fixedly connected with the inner wall of the storage box. The inside of the fixed disk is provided with a movable groove. The inner wall of the movable groove is slidably connected with the outer surface of the movable block. The top of the movable block is fixedly connected with a first spring. The top of the first spring is fixedly connected with the inner wall of the movable groove. The outer surface of the rotating shaft is fixedly connected with a driving wheel. The resilience of the first spring can make the stirring rod move quickly.

[0008] Further, a driven wheel is meshed and connected to the bottom of the driving wheel. The bottom of the driving wheel penetrates through the screening box and extends into the interior. An air flow groove is formed inside the screening box. A rotating rod is rotatably connected to the inner wall of the air flow groove. The outer surface of the rotating rod is fixedly connected to the inner wall of the driven wheel. A fan is fixedly connected to the back of the rotating rod. An ash collection groove is inserted into the right side of the screening box. The cooperation of the driving wheel and the driven wheel enables the fan to suck external air flow into the air flow groove.

[0009] Further, the screening mechanism includes a flow groove formed inside the screening box. A fixing frame is inserted into the screening box. A filter plate is fixedly connected to the inner wall of the fixing frame. A groove is formed at the top of the fixing frame. Since the filter plate is inclined and the holes of the filter plate are from small to large from left to right, when the material flows to the appropriate holes, it will fall through the filter plate into the collection box.

[0010] Further, a collection box is inserted into the front of the screening box. A handle is fixedly connected to the left side of the fixing frame. An extrusion groove is formed inside the screening box. A second spring is fixedly connected to the inner wall of the extrusion groove. The bottom of the second spring is fixedly connected to a convex block. The outer surface of the convex block is adapted to the inner wall of the groove. The convex block is spherical. So when the fixing frame moves to the left, the convex block will be squeezed into the extrusion groove to complete the disassembly of the fixing frame.

[0011] The utility model has the following beneficial effects:

[0012] 1. By arranging the stirring rod in the utility model, when the motor is started, the rotating shaft rotates, and the rotating disk rotates driven by the rotating shaft. While the rotating disk rotates, the stirring rod will expand and contract along the sliding groove. And while the stirring rod moves, it will drive the movable block to squeeze the first spring. The material inside the storage box is stirred through the movement of the stirring rod to prevent blockage and abnormal feeding.

[0013] 2. By arranging the filter plate in the utility model, the cleaned material will flow onto the filter plate through the flow groove. Since the filter plate is inclined and the holes of the filter plate are from small to large from left to right, when the material flows to the appropriate holes, it will fall through the filter plate into the collection box for screening and collection. When the filter plate needs to be replaced, pull the handle to the left. When the handle moves to the left, it drives the fixing frame to move. And since the convex block is spherical, when the fixing frame moves to the left, the convex block will be squeezed into the extrusion groove to complete the disassembly of the fixing frame.

[0014] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. Description of the Drawings

[0025] Please refer to Figure 1-6As shown in the figure, the utility model is a grain screening device, including an anti-blocking mechanism 1 and a storage box 101. The bottom of the anti-blocking mechanism 1 is provided with a screening mechanism 2. The bottom of the storage box 101 is fixedly connected with a screening box 201. The top of the screening box 201 is fixedly connected with a fixed platform 102. The top of the fixed platform 102 is fixedly connected with a motor 103. The bottom output end of the motor 103 is fixedly connected with a rotating shaft 118. The front of the rotating shaft 118 penetrates through the storage box 101 and extends to the inside. The front of the rotating shaft 118 is fixedly connected with a rotating disk 110. The front of the rotating disk 110 is provided with a sliding groove 111. The inner wall of the sliding groove 111 is slidably connected with a stirring rod 112. One end of the stirring rod 112 away from the rotating disk 110 is fixedly connected with a movable block 115. The outer surface of the stirring rod 112 contacts a fixed disk 113. When the motor 103 is started, it drives the rotating shaft 118 to rotate. The rotating disk 110 is driven to rotate by the rotation of the rotating shaft 118. While the rotating disk 110 is rotating, the stirring rod 112 will expand and contract along the sliding groove 111. And while the stirring rod 112 is moving, it will drive the movable block 115 to squeeze the first spring 116. The materials inside the storage box 101 are stirred by the movement of the stirring rod 112 to prevent blockage and abnormal feeding.

[0026] The front of the fixed disk 113 is fixedly connected with the inner wall of the storage box 101. An activity groove 114 is opened inside the fixed disk 113. The inner wall of the activity groove 114 is slidably connected with the outer surface of the movable block 115.

[0027] The top of the movable block 115 is fixedly connected with a first spring 116. The top of the first spring 116 is fixedly connected with the inner wall of the activity groove 114. The outer surface of the rotating shaft 118 is fixedly connected with a driving wheel 104.

[0028] The bottom of the driving wheel 104 is meshed with a driven wheel 108. The bottom of the driving wheel 104 penetrates through the screening box 201 and extends to the inside.

[0029] An air flow groove 105 is opened inside the screening box 201. The inner wall of the air flow groove 105 is rotatably connected with a rotating rod 106. The outer surface of the rotating rod 106 is fixedly connected with the inner wall of the driven wheel 108. The back of the rotating rod 106 is fixedly connected with a fan 107. A dust collection groove 117 is inserted on the right side of the screening box 201.

[0030] The screening mechanism 2 includes a flow channel 210 opened inside the screening box 201. A fixed frame 203 is inserted into the screening box 201. A filter plate 204 is fixedly connected to the inner wall of the fixed frame 203. A groove 207 is opened at the top of the fixed frame 203. The cleaned material will flow onto the filter plate 204 through the flow channel 210. Since the filter plate 204 is inclined and the holes of the filter plate 204 are from small to large from left to right, when the material flows to the appropriate holes, it will fall into the collection box 205 through the filter plate 204 for screening and collection. When the filter plate 204 needs to be replaced, pull the handle 202 to the left. When the handle 202 moves to the left, it pulls the fixed frame 203 to move. And the convex block 206 is spherical, so when the fixed frame 203 moves to the left, the convex block 206 will be squeezed into the extrusion groove 208 to complete the disassembly of the fixed frame 203.

[0031] A collection box 205 is inserted into the front of the screening box 201. A handle 202 is fixedly connected to the left side of the fixed frame 203. An extrusion groove 208 is opened inside the screening box 201.

[0032] A spring two 209 is fixedly connected to the inner wall of the extrusion groove 208. The spring two 209 is fixedly connected to the bottom of a convex block 206. The outer surface of the convex block 206 is adapted to the inner wall of the groove 207.

[0033] A specific application of this embodiment is as follows: First, the staff pour the materials into the storage box 101, and then start the motor 103. When the motor 103 starts, it drives the rotating shaft 118 to rotate. The rotation of the rotating shaft 118 drives the rotating disk 110 to rotate. While the rotating disk 110 is rotating, the stirring rod 112 will expand and contract along the sliding groove 111. And while the stirring rod 112 is moving, it will drive the movable block 115 to squeeze the first spring 116. The materials inside the storage box 101 are stirred by the movement of the stirring rod 112 to prevent blockage, which may cause abnormal material feeding. When the rotating shaft 118 rotates, it drives the driving wheel 104 to rotate. The rotation of the driving wheel 104 drives the driven wheel 108 to rotate. Then, the rotation of the driven wheel 108 drives the rotating rod 106 to rotate. While the rotating rod 106 is rotating, it drives the fan 107 to rotate. Then, the air flow outside is inhaled into the air flow groove 105 through the rotation of the fan 107 and moves forward. When the air flow moves to the innermost part, it is ejected through the ejection port. Then, the remaining debris in the materials is blown away by the ejected air flow and falls into the ash collection groove 117. The materials that have been cleaned will flow to the filter plate 204 through the flow groove 210. Since the filter plate 204 is inclined and the holes from left to right are gradually increasing in size, when the materials flow to the appropriate holes, they will fall through the filter plate 204 into the collection box 205 for screening and collection. When the filter plate 204 needs to be replaced, pull the handle 202 to the left. When the handle 202 moves to the left, it pulls the fixing frame 203 to move. And since the convex block 206 is spherical, when the fixing frame 203 moves to the left, the convex block 206 will be squeezed into the extrusion groove 208 to complete the disassembly of the fixing frame 203.
