Description

Technical Field

[0001] The utility model belongs to the technical field of impurity removal of cereal raw materials, and particularly relates to an impurity separator for cereal raw materials. Background Art

[0002] During the impurity removal process of cereal raw materials, a specific gravity stoner is used to screen stones and metal blocks in the raw materials. The specific gravity stoner drives the raw materials to vibrate through the vibration of the sieve plate. During actual operation, it is necessary to adjust the sieve plate to an appropriate vibration frequency to screen the stones in the raw materials. However, when the vibration frequency of the sieve plate changes, the screening effect of the specific gravity stoner will decline, resulting in stones falling downward together with the wheat raw materials. Due to the fast falling speed of the stones and raw materials, and the fact that some stones are close in color to the wheat, it is difficult for the staff beside the machine to notice the stones falling with the raw materials, leading to the inability to timely detect the decline in the screening effect of the specific gravity stoner, or even if the stones are found to be falling downward, they cannot be blocked in time from falling into the raw material pile. This not only affects the screening effect of the raw materials, but also requires secondary screening of the already screened raw materials due to the mixture of raw materials, seriously affecting the screening efficiency of the raw materials. Content of the Utility Model

[0003] The utility model provides an impurity separator for cereal raw materials, which has the characteristics of being able to reserve sufficient time for observing and processing the screened raw materials, timely detecting the decline in the screening effect of the specific gravity stoner main body on the raw materials, and avoiding the reduction of work efficiency caused by the need for secondary screening after the raw materials are mixed.

[0004] The utility model provides the following technical solution: an impurity separator for cereal raw materials, including a specific gravity stoner main body and a discharge chute plate. One side of the specific gravity stoner main body is provided with a supporting arc plate. The side wall of the supporting arc plate is fixedly connected with an "L"-shaped outward expanding port plate. Inside the supporting arc plate is a raw material spreading and transporting disc. The inner wall of the supporting arc plate is fixedly connected with an arc-shaped notch supporting block. The raw material spreading and transporting disc is rotatably connected to the inner wall of the arc-shaped notch supporting block. The top of the raw material spreading and transporting disc is provided with a raw material cleaning plate, and the raw material cleaning plate is fixedly connected with the inner wall of the supporting arc plate.

[0005] Wherein, the diameter of the raw material spreading and transporting disc is smaller than the inner diameter of the supporting arc plate, and the bottom end of the discharge chute plate is located above the raw material spreading and transporting disc.

[0006] Wherein, the center of the bottom end of the raw material spreading and transporting disc is fixedly connected with a driving motor, and the bottom end of the driving motor is fixedly connected with a frame support seat.

[0007] Wherein, the bottom end of the supporting arc plate is fixedly connected with a feeding funnel, and the outer wall of the supporting arc plate is fixedly connected with a side connecting vibration rod, and the side connecting vibration rod is fixedly connected with the specific gravity stoner main body.

[0008] Among them, a material guiding plate is rotatably connected to the bottom end of the material guiding funnel, and the material guiding plate is inclined.

[0009] Among them, a screening material conveyor belt is arranged below the supporting arc plate. A support frame is fixedly connected to the side wall of the screening material conveyor belt. The support frame is fixedly connected to the material guiding funnel, and the height of the bottom end of the material guiding plate is higher than the height of the top end of the screening material conveyor belt.

[0010] The beneficial effects of the present utility model are as follows: The raw material paving and transporting disc receives the raw materials discharged from the discharge chute plate, so that the materials will rotate a certain distance within the "L"-shaped outward expansion plate and then be discharged downward through the gap between the raw material paving and transporting disc and the supporting arc plate, leaving sufficient time for the staff to observe and process the screened raw materials, promptly discovering that the screening effect of the specific gravity stoner main body on the raw materials decreases. The adjustment of the discharge position of the raw materials by the material guiding plate can prevent the screened raw materials from being discharged into the raw materials with good screening effect after the screening effect of the specific gravity stoner main body decreases, avoiding the need for secondary screening after the raw materials are mixed and reducing work efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1 - 3, the present utility model provides the following technical solutions: An impurity separator for cereal raw materials, including a specific gravity stoner main body 1 and a discharge chute plate 11. On one side of the specific gravity stoner main body 1, there is a support arc plate 2. On the side wall of the support arc plate 2, an "L"-shaped outward expanding plate 21 is fixedly connected. Inside the support arc plate 2, there is a raw material spreading and transporting disk 22. On the inner wall of the support arc plate 2, an arc-shaped notch support block 23 is fixedly connected. The raw material spreading and transporting disk 22 is rotatably connected to the inner wall of the arc-shaped notch support block 23. At the top of the raw material spreading and transporting disk 22, there is a raw material cleaning plate 24, and the raw material cleaning plate 24 is fixedly connected to the inner wall of the support arc plate 2.

[0017] In this implementation scheme: The specific gravity stoner main body 1 is used to screen the stone grains and metal impurities in the cereal raw materials. The cereal raw materials are discharged downward from the discharge chute plate 11. The raw materials fall onto the top of the raw material spreading and transporting disk 22 via the discharge chute plate 11. After the raw material spreading and transporting disk 22 drives the materials to rotate a certain distance inside the "L"-shaped outward expanding plate 21, the materials are discharged downward through the gap between the raw material spreading and transporting disk 22 and the support arc plate 2 under the action of the raw material cleaning plate 24. During this process, the "L"-shaped outward expanding plate 21 can increase the space for the materials to fall, so that the materials can fall downward more smoothly, avoiding the accumulation of materials and affecting the staff's identification of the materials on the raw material spreading and transporting disk 22. During the rotation of the raw materials on the raw material spreading and transporting disk 22, sufficient time can be reserved for the staff to observe and process the screened raw materials, and timely discover that the screening effect of the specific gravity stoner main body 1 on the raw materials has decreased. When there are no stone grains and metal impurities doped in the raw materials, the opening of the guide plate 29 is located at the top of the screening material conveyor belt 3, and the material diameter falls onto the top of the screening material conveyor belt 3 via the guide plate 29. When there are stone grains and metal impurities doped in the materials, the staff rotates the guide plate 29 by 90 degrees, adjusts the outlet of the guide plate 29 to one side of the screening material conveyor belt 3, and discharges the raw materials doped with stone grains to one side of the screening material conveyor belt 3, avoiding the screened raw materials being discharged into the raw materials with good screening effect after the screening effect of the specific gravity stoner main body 1 on the raw materials has decreased, and avoiding the reduction of work efficiency due to the secondary screening after the raw materials are mixed. In the actual use process, a visual recognition device can be installed at the top of the support arc plate 2 according to the actual situation to identify the raw materials on the top of the raw material spreading and transporting disk 22, and a motor can be installed in the guide funnel 27 to automatically adjust the position of the guide plate 29 to replace the manual operation of the staff.

[0018] The diameter of the raw material leveling and transporting disc 22 is smaller than the inner diameter of the supporting arc plate 2, and the bottom end of the discharge chute plate 11 is located above the raw material leveling and transporting disc 22; there is a gap between the raw material leveling and transporting disc 22 and the supporting arc plate 2, so that the raw materials can fall downward through the gap. By setting the arc-shaped notch support block 23, the raw material leveling and transporting disc 22 can be supported, and at the same time, part of the gap between the supporting arc plate 2 and the raw material leveling and transporting disc 22 can be blocked, so that the raw materials can fall downward only after moving a certain distance.

[0019] The center of the bottom end of the raw material leveling and transporting disc 22 is fixedly connected with a driving motor 25, and the bottom end of the driving motor 25 is fixedly connected with a frame support seat 26; by setting the driving motor 25, the raw material leveling and transporting disc 22 can be driven to rotate, and the frame support seat 26 can support the driving motor 25, and the frame support seat 26 is a frame that can reserve enough space to avoid hindering the continuous downward movement of the raw materials.

[0020] The bottom end of the supporting arc plate 2 is fixedly connected with a material guiding funnel 27, and the outer wall of the supporting arc plate 2 is fixedly connected with a side connecting vibrating rod 28, and the side connecting vibrating rod 28 is fixedly connected with the specific gravity stoner main body 1; by setting the material guiding funnel 27, the materials falling from the raw material leveling and transporting disc 22 can be guided, so that the raw materials can move towards the central opening at the bottom end of the material guiding funnel 27. By setting the side connecting vibrating rod 28, it can be connected with the specific gravity stoner main body 1, and the vibration of the specific gravity stoner main body 1 can drive the supporting arc plate 2 and the material guiding funnel 27 to vibrate, so as to accelerate the downward movement of the raw materials.

[0021] The bottom end of the material guiding funnel 27 is rotatably connected with a material guiding plate 29, and the material guiding plate 29 is inclined; by setting the material guiding plate 29, the discharging position of the raw materials can be adjusted to avoid the raw materials mixed with stone particles falling on the screening material conveyor belt 3 and causing the raw materials to be mixed.

[0022] A screening material conveyor belt 3 is arranged below the supporting arc plate 2. The side wall of the screening material conveyor belt 3 is fixedly connected with a support frame 31, and the support frame 31 is fixedly connected with the material guiding funnel 27. The height of the bottom end of the material guiding plate 29 is higher than the height of the top end of the screening material conveyor belt 3; in actual use, multiple specific gravity stoner main bodies 1 and multiple supporting arc plates 2 are arranged in parallel, and the screening material conveyor belt 3 is arranged below the multiple supporting arc plates 2 to carry and transfer the raw materials, and the support frame 31 plays a supporting role.

[0023] The working principle and usage process of the present utility model: The main body 1 of the specific gravity stoner screens the stones and metal impurities in the cereal raw materials. The cereal raw materials are discharged downward from the discharge chute plate 11, and the raw materials fall onto the top of the raw material spreading and transporting disc 22 via the discharge chute plate 11. After the raw material spreading and transporting disc 22 drives the material to rotate a certain distance within the "L"-shaped outward expansion plate 21, the material is discharged downward through the gap between the raw material spreading and transporting disc 22 and the support arc plate 2 under the action of the raw material cleaning plate 24. During the rotation of the raw material on the raw material spreading and transporting disc 22, sufficient time can be reserved for the staff to observe and process the screened raw materials, and it can be timely found that the screening effect of the main body 1 of the specific gravity stoner on the raw materials decreases. When there are no stones and metal impurities doped in the raw materials, the opening of the guide plate 29 is located at the top of the screening material conveyor belt 3, and the material diameter falls onto the top of the screening material conveyor belt 3 via the guide plate 29. When there are stones and metal impurities doped in the material, the staff rotates the guide plate 29 by 90 degrees and adjusts the outlet of the guide plate 29 to one side of the screening material conveyor belt 3. The raw materials doped with stones are discharged on one side of the screening material conveyor belt 3, so as to avoid the screened raw materials being discharged into the raw materials with good screening effect after the screening effect of the main body 1 of the specific gravity stoner on the raw materials decreases.
