Description

Technical Field

[0001] The present application relates to the technical field of peanut processing, and in particular to a peanut impurity removal device. Background Art

[0002] Impurities in peanuts, such as dirt and stones, can seriously affect their edible quality. These impurities not only make the peanuts taste worse, but may also carry unhealthy bacteria or viruses, posing a threat to the health of consumers. In the peanut processing process, such as oil extraction and peanut butter making, the presence of impurities may cause equipment failure or affect product quality. Removing impurities can ensure the smooth progress of the processing process while improving the purity and quality of the product.

[0003] In the prior art, peanuts and impurities are separated by means of a vibrating screen, but this method is inefficient. At present, there is a device that uses wind power to separate peanuts and impurities. Since the density of peanuts and impurities is different, the peanuts will be blown together by the wind. However, as the number of peanuts increases, there will be more stones on the platform. Therefore, the impurities on the platform need to be cleaned multiple times, resulting in reduced efficiency.

[0004] Therefore need a kind of peanut impurity removal device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a peanut impurity removal device to solve the above-mentioned technical problems.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: a peanut impurity removal device includes a transportation device, the transportation device includes a conveyor belt and a conveyor frame, one end of the conveyor frame is provided with a driving shaft rotatably connected to the conveyor frame, and the other end is provided with a driven shaft rotatably connected to the conveyor frame, one end of the conveyor belt is sleeved on the driving shaft, and the other end is sleeved on the driven shaft, a motor is fixedly arranged below the conveyor frame, a driving gear is fixedly arranged at the output end of the motor, a driven gear is fixed on the driving shaft, a drive chain is sleeved between the driving gear and the driven gear, the drive chain and the driving gear and the driven gear are meshingly connected, a rotating shaft rotatably connected to the conveyor frame is provided in the middle of the conveyor frame, a cam is fixedly connected to the middle of the rotating shaft, a second motor is provided on the rotating shaft, the second motor is fixedly connected to the conveyor frame, the output end of the second motor is fixedly connected to the rotating shaft, and a fan is provided at one end of the conveyor frame.

[0007] By adopting the above technical solution, peanuts that need to remove impurities are placed on the conveyor belt, the first motor and the second motor are started, and the first motor drives the conveyor belt to be transported in the direction of the fan. When the conveyor belt is transported to the position of the cam, the cam drives the conveyor belt to vibrate, and the peanuts and stones on the conveyor belt jump with the vibration of the conveyor belt. As the fan blows, the density of peanuts is less than that of stones, so the peanuts will be moved toward the other end of the fan, and the stones will continue to move to both sides of the conveyor belt due to the vibration of the conveyor belt until they fall into the gap on both sides.

[0008] Furthermore, the conveyor belt is inclined, one end of the conveyor frame close to the fan is higher than the other end, and the air outlet of the fan is also inclined downward.

[0009] By adopting the above technical solution, the efficiency of collecting peanuts can be improved by tilting the fan, the air outlet and the conveyor belt.

[0010] Furthermore, a baffle is provided at one end of the conveying frame away from the fan, and two sides of the baffle are fixedly connected to the conveying frame.

[0011] By adopting the above technical solution, since the conveyor belt is set at an angle, in order to prevent smooth stones from rolling out of one end of the transmission belt, the baffle can solve this problem well. After the baffle blocks the smooth stones, they continue to fall into the gaps on both sides as the conveyor belt continues to be transported to the cam position.

[0012] Furthermore, the surface of the conveyor belt is provided with friction lines.

[0013] By adopting the above technical solution, the friction lines can increase the friction between the stones and the conveyor belt, thereby better preventing the smooth stones from moving to the end of the conveyor belt.

[0014] Furthermore, the friction pattern is directed from the fan toward the other end.

[0015] By adopting the above technical solution, the wind force of the fan on the conveyor belt can be increased, so that the peanuts can be better screened.

[0016] Furthermore, the friction lines are streamlined.

[0017] By adopting the above technical solution, the streamlined setting can increase the wind force of the fan on the conveyor belt, and the peanuts on the conveyor belt can still be blown without vibration, thereby improving the screening efficiency.

[0018] Furthermore, a centralized pipe is fixedly arranged between the conveyor belt and the conveyor frame, and an impurity recovery box is fixedly arranged at one end of the centralized pipe away from the conveyor belt.

[0019] By adopting the above technical solution, as the conveyor belt vibrates, the vibration force will bring the stones on the conveyor belt to both sides of the conveyor belt, and the stones will fall into the centralized pipe and finally fall into the impurity recovery box for collection.

[0020] Furthermore, a collection box is provided at one end of the conveyor belt away from the fan.

[0021] By adopting the above technical solution, after the fan blows the vibrated peanuts to the end of the conveyor belt, they will enter the collection box for unified collection.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. A cam is set in the middle of the conveyor frame. When the peanuts that need to be cleaned of impurities are conveyed to the middle of the conveyor belt, the rotation of the cam drives the conveyor belt to vibrate, and some heavier impurities such as stones will keep moving to the sides until they fall into the gaps on both sides. The density of peanuts is smaller than that of stones, so they move in the direction of the wind under the blowing of the fan. Impurities are sorted out from peanuts in the above way, achieving the purpose of removing impurities. At the same time, impurities can be removed from the conveyor belt, reducing the number of times the conveyor belt needs to be cleaned;

[0024] 2. The efficiency of collecting peanuts is improved by tilting the conveyor belt and the fan. A baffle is set on the end of the conveyor frame away from the fan to prevent smooth stones from rolling from the conveyor belt into the collected peanuts, reducing the impurities in the peanuts after the impurities are separated;

[0025] 3. By setting up impurity recovery boxes and collection boxes, peanuts and impurities can be collected separately and centrally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Example, see Figure 1 , Figure 2 A peanut impurity removal device includes a transport device, which includes a conveyor belt 1 and a conveyor frame 2. A driving shaft 3 rotatably connected to the conveyor frame 2 is provided at one end of the conveyor frame 2, and a driven shaft 4 rotatably connected to the conveyor frame is provided at the other end. One end of the conveyor belt 1 is sleeved on the driving shaft 3, and the other end is sleeved on the driven shaft 4. A first motor 30 is fixedly arranged below the conveyor frame 2, a driving gear 5 is fixedly arranged on the output end of the first motor 30, a driven gear 50 is fixed on the driving shaft 3, a driving chain 51 is sleeved between the driving gear 5 and the driven gear 50, and the driving chain 51 is meshingly connected with the driving gear 5 and the driven gear 50. A rotating shaft 6 rotatably connected to the conveyor frame 2 is provided in the middle of the conveyor frame 2, and a cam 60 is fixedly connected to the middle of the rotating shaft 6. A second motor 61 is arranged on the rotating shaft 6, and the second motor 61 is fixedly connected to the conveying frame 2. The output end of the second motor 61 is fixedly connected to the rotating shaft 6. A fan 7 is arranged at one end of the conveying frame 2. The conveyor belt 1 is inclined. The end of the conveying frame 2 close to the fan 7 is higher than the other end. The air outlet of the fan 7 is also inclined downward. A baffle 21 is arranged at the end of the conveying frame 2 away from the fan 7. Both sides of the baffle 21 are fixedly connected to the conveying frame 2. Friction lines 10 are provided on the surface of the conveyor belt 1. The friction lines 10 are streamlined from the fan 7 to the other end. A concentrated pipe 8 is fixedly arranged between the conveyor belt 1 and the conveying frame 2. An impurity recovery box 80 is fixedly arranged at the end of the concentrated pipe 8 away from the conveyor belt 1, and a collecting box 9 is arranged at the end of the conveyor belt 1 away from the fan 7.

[0031] In this embodiment, the first motor 30 fixedly connected to the bottom of the conveyor frame 2 rotates, driving the driving gear 5 to rotate, and the drive chain 51 and the driven gear 50 meshing with the driving gear 5 rotate, so that the driving shaft 3 rotates, driving the conveyor belt 1 sleeved on the driving shaft 3 and the transmission shaft to rotate, so that objects such as peanuts can move on the conveyor belt 1. The air outlet directions of the conveyor belt 1 and the fan 7 are both inclined downward. When using this application, the peanuts and impurities are driven by the friction lines 10 to move toward the air outlet direction under the rotation of the conveyor belt 1, and the end of the conveyor frame 2 away from the fan 7 is provided with a baffle 21 to block a part of the stones rolling obliquely along the direction of the conveyor belt 1. The second motor 61 rotates to drive the rotating shaft 6 and the cam 60 to rotate. The rotation of the cam 60 causes the conveyor belt 1 to vibrate up and down. The stones and other impurities with higher density on the conveyor belt 1 move to both sides of the conveyor belt 1 under the vibration. The peanuts move in the direction of the wind force under the action of the fan 7. The peanuts and impurities are separated in different directions. The impurity recovery box 80 and the collection box 9 under the conveyor belt 1 collect the impurities and peanuts respectively.

[0032] Specific implementation process:

[0033] First, peanuts containing impurities such as sand and stones are placed on the conveyor belt 1 of the present application, and the first motor 30 and the second motor 61 are started. The first motor 30 drives the conveyor belt 1 to rotate toward the fan 7, and the friction lines 10 on the conveyor belt 1 drive the peanuts and impurities thereon to move obliquely upward. The baffle 21 blocks a part of the stones rolling obliquely downward along the conveyor belt 1 to prevent them from falling into the collection box 9. Under the action of the friction lines 10, the rolling stones are brought back to the conveyor belt 1 and returned to the middle of the conveyor belt 1. When the peanuts and impurities are transported to the position of the cam 60, the cam 60 fixedly connected to the rotating shaft 6 rotates to vibrate the conveyor belt 1, and the peanuts and stones on the conveyor belt 1 will jump due to the vibration of the conveyor belt 1. With the blowing of the fan 7, since the density of peanuts is less than that of stones, the peanuts will be moved toward the other end of the fan 7 and collected in the collection box 9. The stones will continuously move to both sides under the vibration of the conveyor belt 1 until they fall into the gaps on both sides and fall into the centralized pipe 8, and are finally collected into the impurity recovery box 80, thus completing the separation of peanuts and impurities.

Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
