Abstract
Description
Technical Field
[0001] The invention belongs to the field of machinery, and in particular relates to a flat-rubbing peanut shelling machine. Background Art
[0002] In the prior art, most peanut shelling machines adopt a horizontal drum or a three-dimensional drum structure, in which the peanuts are repeatedly rubbed in the drum to crack and break the peanut shells to complete the shelling. There are also peanut shelling machines that use a double roller extrusion method. The peanuts are repeatedly rubbed in the shelling chamber under the action of the rotating drum, so that the shells are broken and the peanut shells are separated through the shelling augers and shelling concave screens. Although peanut shelling machines with these structures can achieve efficient peanut shelling, the peanut kernel breakage rate is high, and they are not suitable for shelling breeding peanuts.

The two sides of the rubbing frame 8 are fixedly connected to the frame 1. The main support frame 4 and the auxiliary support frame 5 are both connected to the slideways 23 on both sides of the frame 1 through rollers. Two main rubbing pull rods 15 are provided under the main support frame 4. The two ends of the main rubbing pull rod 15 are respectively provided with eccentric bearing sleeves 20 and eccentric bearing sleeves 16. The eccentric bearing sleeves 20 and the main support frame are connected to the main support frame 4. The auxiliary support frame 5 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 arranged on the main rubbing motor bracket 19, and the main rubbing motor 7 drives the main rubbing rod 15 and the main support frame 4 to reciprocate along the slide 23 through the main eccentric wheel 17; a secondary rubbing rod 26 is provided under the auxiliary support frame 5, and eccentric bearings are provided at both ends of the secondary rubbing rod 26. The eccentric bearing sleeve 28 and the eccentric bearing sleeve 25 are connected to the auxiliary support frame 5, the eccentric bearing sleeve 25 is connected to the auxiliary eccentric wheel 24, the auxiliary eccentric wheel 24 is connected to the auxiliary rubbing motor 11, and the auxiliary rubbing motor 11 drives the auxiliary rubbing pull rod 26 and the auxiliary support frame 5 to reciprocate along the slide 23 through the auxiliary eccentric wheel 24; the distance between the rubbing frame 8 and the main screen frame 9 or the rubbing frame 8 and the auxiliary screen frame 10 is adjusted by the spacing adjustment mechanism 12, and the spacing adjustment mechanism 12 It includes a screw rod 22 provided on the frame 1, a spring 13 provided on the screw rod 22, a nut 14 provided above the spring 13, and the four corners of the rubbing frame 8 are connected to the screw rod 22 through collars 803; a plurality of pressing plate seats 21 are provided on the four sides below the rubbing frame 8, and a pressing plate 211 is provided on the pressing plate seat 21. A relatively closed space is formed between the pressing plate 211 and the rubbing plate 801 and the main screen frame 9 or between the pressing plate 211 and the rubbing frame 801 and the auxiliary screen 10 to prevent peanuts from falling between the rubbing frame and the screen; The distance between each rubbing board strip 1201 on the rubbing board 12 matches the size of the shelled peanuts; the size of the sieve holes on the main screen frame 9 and the auxiliary screen frame 10 matches the size of the shelled peanuts; the mesh diameter of the main screen frame 9 is larger than the mesh diameter of the auxiliary screen frame 10; the flat-rubbing peanut sheller cooperates with the bucket loader 29 to load materials. The bucket loader 29 is arranged above the flat-rubbing peanut sheller frame 1 and can be moved for loading. The power of the main rubbing motor 7 and the auxiliary rubbing motor 11 are 5.5KW and 2.2KW respectively.
[0011] Specifically, when the flat-rubbing peanut sheller is working, the shelled peanuts that have been sorted and de-stoned by the stone remover 32 are first sent to the main screen frame 9 above the sheller through the bucket loader 29. According to the size of the peanuts to be shelled, the distance between the main screen frame 9 and the auxiliary screen frame 10 and the upper rubbing plate 801 can be fine-tuned by the spacing adjustment mechanism 12. When the distance is too large, the nut 14 is screwed down to press the spring 13 downward to make the rubbing plate 801 move downward and reduce the distance between the two. Conversely, when the distance is too small, the nut 14 is screwed upward appropriately to press the spring 13 upward to make the rubbing plate 801 move upward and increase the distance between the two. After adjusting the distance, the main rubbing motor 7 is started and the main The rubbing rod 15 drives the main screen frame 9 to do reciprocating motion. The peanut shells are peeled off through the gentle reciprocating motion between the main screen frame 9 and the rubbing plate 801 on the rubbing frame 8. The peeled peanut kernels fall from the sieve holes on the main screen frame 9 to 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 peanut shells that come out and the peanuts that are not rubbed into place fall from the gap between the main screen frame 9 and the auxiliary screen frame 10 to the conveyor belt 3 below. The shelled peanuts with incomplete particles fall directly from the sieve holes on the main screen frame 9 to the conveyor belt 3 without being shelled, and enter the next sorting process from the outlet 30 together with the peanuts. After the sorting machine 31 sorts out the peanuts that have not been rubbed in place and the peanuts with incomplete particles, they are sent to the auxiliary screen frame 10 by the feeding machine 29. The peanut particles of the second rubbing are smaller than the peanut particles of the main rubbing. The distance between the auxiliary screen frame 10 and the upper rubbing plate 801 can be fine-tuned by the spacing adjustment mechanism 12. After the distance is adjusted, the auxiliary rubbing motor 11 drives the auxiliary rubbing pull rod 26, thereby driving the auxiliary screen frame 10 to do reciprocating motion. The peanut shells are peeled off through the gentle reciprocating motion between the auxiliary screen frame 10 and the rubbing plate 801 on the rubbing frame 8. The peeled peanuts fall from the sieve holes on the auxiliary screen frame 10 onto the conveyor belt 3 below, and are driven by the conveying motor 6 to be transported to the exit 30 at the end of the main frame.
[0012] The main screen frame 9 and the auxiliary screen frame 10 can be equipped with suitable sieve holes according to the peanut variety and the size of the shelled peanuts. The main screen frame and the auxiliary screen frame can be replaced each time the shelling is performed.
[0013] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
