Description

Technical Field

[0001] This utility model belongs to the field of machinery, specifically relating to a flat-rolling peanut shelling machine. Background Technology

[0002] In existing technologies, most peanut shelling machines adopt a horizontal drum or three-dimensional drum structure. Peanuts are repeatedly rubbed inside the drum to crack and break the shells, thus completing the shelling process. Others use a method of pressing peanuts with rollers. In the shelling chamber, the peanuts are repeatedly rubbed by the rotating drum, causing the outer shell to break. The shells are then separated by a shelling auger and a shelling concave screen. Although these types of peanut shelling machines achieve efficient shell removal, the peanut kernel breakage rate is relatively high, making them unsuitable for shelling breeding peanuts.

[0022] See attached document Figure 1-6A flat-rolling peanut shelling machine includes a frame 1, a main frame 2 mounted on the frame 1, a conveyor belt 3 mounted on the main frame 2, the conveyor belt 3 being connected to a conveyor motor 6 located at one end of the frame 1, a main support frame 4 and a secondary support frame 5 mounted above the main frame 2, a main screen frame 9 mounted on the main support frame 4, and a secondary screen frame 10 mounted on the secondary support frame 5, with a material-rolling frame 8 mounted above both the main screen frame 9 and the secondary screen frame 10. A washboard 801 has multiple washboard strips 802 arranged at equal intervals. Each washboard strip 802 has a spiral thread. The material washing frame 8 is fixedly connected to the machine frame 1 on both sides. The main support frame 4 and the auxiliary support frame 5 are both connected to the slide rails 23 on both sides of the upper part of the machine frame 1 via rollers. Two main washing pull rods 15 are located below the main support frame 4. Eccentric bearing sleeves 20 and 16 are respectively provided at both ends of the main washing pull rods 15. The eccentric bearing sleeves 20 and 16 are connected to the main support rods 15. The support frame 4 is connected, the eccentric bearing sleeve 16 is connected to the main eccentric wheel 17, the main eccentric wheel 17 is connected to the bearing seat 18, the main rubbing motor 7 is connected to the main eccentric wheels 17 at both ends through the bearing seat 18, the main rubbing motor 7 is mounted on the main rubbing motor bracket 19, the main rubbing motor 7 drives the main rubbing tie rod 15 and the main support frame 4 to reciprocate along the slide rail 23 through the main eccentric wheels 17; the auxiliary support frame 5 is provided with an auxiliary rubbing tie rod 26 below, and the auxiliary rubbing tie rod 26 is provided with eccentric shafts at both ends. The eccentric bearing sleeve 28 and eccentric bearing sleeve 25 are connected. The eccentric bearing sleeve 28 is connected to the secondary support frame 5, and the eccentric bearing sleeve 25 is connected to the secondary eccentric wheel 24. The secondary eccentric wheel 24 is connected to the secondary rubbing motor 11. The secondary rubbing motor 11 drives the secondary rubbing rod 26 and the secondary support frame 5 to reciprocate along the slide rail 23 through the secondary eccentric wheel 24. The distance between the rubbing frame 8 and the main screen frame 9 or between the rubbing frame 8 and the secondary screen frame 10 is adjusted by the spacing adjustment mechanism 12. The machine includes a lead screw 22 mounted on the frame 1, with a spring 13 on the lead screw 22 and a nut 14 above the spring 13. The four corners of the material rubbing frame 8 are connected to the lead screw 22 via collars 803. Multiple pressure plate seats 21 are provided around the bottom of the material rubbing frame 8, with pressure plates 211 on each seat. The pressure plates 211, the rubbing plates 801, the main screen frame 9, or the pressure plates 211, the material rubbing frame 8, and the secondary screen frame 10 form a relatively sealed space to prevent peanuts from falling between the material rubbing frame and the screen. The distance between each rubbing strip 802 on plate 801 is matched with the size of the peanuts to be shelled; the size of the screen holes on the main screen frame 9 and the auxiliary screen frame 10 is matched with the size of the peanuts to be shelled; the diameter of the mesh hole on the main screen frame 9 is larger than the diameter of the mesh hole on the auxiliary screen frame 10; the flat rubbing peanut shelling machine is used in conjunction with the bucket feeder 29 for feeding, and the bucket feeder 29 is located above the frame 1 of the flat rubbing peanut shelling machine and can be moved for feeding; the power of the main rubbing motor 7 and the auxiliary rubbing motor 11 are 5.5KW and 2.2KW respectively.

[0023] Specifically, when the flat-rolling peanut shelling machine is working, the shelled peanuts, after being sorted and destoned by the destoner 32, are first fed onto the main screen frame 9 above the shelling machine by the bucket-type feeder 29. Depending on the size of the peanuts to be shelled, the distance between the main screen frame 9, the secondary screen frame 10, and the upper rubbing plate 801 can be finely adjusted by the spacing adjustment mechanism 12. When the distance is too large, the nut 14 is turned downwards, pressing the spring 13 downwards, causing the rubbing plate 801 to move downwards, thus reducing the distance between them. Conversely, when the distance is too small, the nut 14 is turned upwards appropriately, causing the spring 13 to move upwards, causing the rubbing plate 801 to move upwards, thus increasing the distance between them. After adjusting the distance, the main rubbing motor 7 is started. The rubbing rod 15 drives the main screen frame 9 to reciprocate. Through the gentle reciprocating motion between the main screen frame 9 and the rubbing plate 801 on the rubbing frame 8, the peanut shells are peeled off. The peeled peanut kernels fall from the screen holes on the main screen frame 9 onto the conveyor belt 3 below. The conveyor motor 6 drives the conveyor belt 3 to the outlet 30 at the end of the main frame. The peeled peanut shells, along with peanuts that were not properly rubbed, fall through the gap between the main screen frame 9 and the secondary screen frame 10 onto the conveyor belt 3 below. Peanuts with shells that are not fully peeled fall directly from the screen holes on the main screen frame 9 onto the conveyor belt 3, and enter the next sorting process from the outlet 30 along with the peanut kernels. After the sorting machine 31 separates the peanuts that were missed due to improper rubbing and the peanuts that are not fully plump, they are sent to the secondary screen frame 10 by the feeder 29. The peanuts rubbed in the second rubbing are smaller than those rubbed in the main rubbing. The distance between the secondary screen frame 10 and the upper rubbing plate 801 can be finely adjusted by the spacing adjustment mechanism 12. After the distance is adjusted, the secondary rubbing motor 11 drives the secondary rubbing rod 26, thereby driving the secondary screen frame 10 to reciprocate. Through the gentle reciprocating motion between the secondary screen frame 10 and the rubbing plate 801 on the rubbing frame 8, the peanut shells are peeled off. The peeled peanuts fall from the screen holes on the secondary screen frame 10 onto the conveyor belt 3 below, and the conveyor motor 6 drives the conveyor belt to the outlet 30 at the end of the main frame.

[0024] The main screen frame 9 and the secondary screen frame 10 can be matched with appropriate screen holes according to the peanut variety and the size of the peanuts to be shelled. The main screen frame and the secondary screen frame can be replaced each time the peanuts are shelled.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
