Description

Technical Field

[0001] The present invention relates to the technical field of nut shelling, and particularly to a nut shelling machine with a blockage prevention function. Background Art

[0002] Traditional nut shelling often relies on manual labor or simple machinery, which is not only time-consuming but also has low efficiency. Nut shelling machines can quickly and efficiently process a large number of nuts, significantly improving production efficiency, especially suitable for large-scale production environments, effectively reducing labor costs. The working stability and high efficiency of the shelling machine reduce errors in manual operations, improve product consistency, and traditional manual shelling is prone to damaging nut kernels due to improper operation, resulting in waste. Modern shelling machines use scientific shelling methods, which can minimize losses, reduce waste products, and improve the utilization rate of resources. At the same time, automated shelling machines can be precisely set according to the type, size, hardness, etc. of nuts, so as to ensure the complete removal of nut shells without damaging nut kernels. This is more accurate than manual operations or traditional mechanical methods, improving the quality and integrity of nut kernels.

Detailed implementation manners

[0028] Refer to Figures 1 to 14 A nut shell-breaking machine with an anti-blocking function as shown, which includes a shell-breaking component 1 for breaking nuts. A plurality of shell-breaking frames 102 and shell-breaking rollers 103 are arranged in the shell-breaking component 1. After the nuts are placed on the shell-breaking rollers 103, they are squeezed with the shell-breaking frames 102 to break the nuts. An upper end of the shell-breaking component 1 is provided with a feeding component 2. The feeding component 2 is used to place the nuts into the shell-breaking component 1. At the same time, the feeding component 2 avoids blockage during feeding by batch feeding, and stirs the nuts to avoid too fast dropping speed of the nuts. A separation component 3 for separating the shells and kernels of the broken nuts is arranged on a side of the shell-breaking component 1. The separation component 3 blows out the lighter shells through the vibration of a screening plate 302 and the blowing of an air separation port 305. The separation component 3 collects the shells. When collecting the shells, a clamping frame 312 is provided to avoid blockage.

[0029] The shell crushing assembly 1 includes a shell crushing box 101, a group of shell crushing frames 102 are slidably arranged on both sides of the shell crushing box 101, two groups of shell crushing rollers 103 are rotatably arranged inside the shell crushing box 101, and multiple groups of grooves are arranged on the shell crushing rollers 103. After the nuts fall on the grooves, the shell crushing rollers 103 are driven to rotate, and the shell crushing rollers 103 drive the nuts and the shell crushing frames 102 to squeeze and complete the shelling of the nuts, and the shell crushing frames 102 are driven to slide on the shell crushing box 101 to change the spacing between the shell crushing frames 102 and the shell crushing rollers 103 to achieve different shelling effects, which is suitable for different kinds of nuts. An adjusting block 108 is slidably arranged at the lower end of the shell crushing box 101, and two groups of cleaning rollers 109 are rotatably arranged on the adjusting block 108. The adjusting block 108 is driven to slide on the shell crushing box 101, and the cleaning rollers 109 are fitted with the shell crushing rollers 103 to crush the shells. 3. After the shell crushing roller 103 crushes the nuts, the shells are likely to remain on the shell crushing roller 103. The cleanliness and crushing efficiency of the shell crushing roller 103 can be improved by wiping with the cleaning roller 109. A feeding port 104 is provided at the upper end of the shell crushing box 101. The nuts enter the shell crushing box 101 through the feeding port 104. A dividing plate 105 is provided on the feeding port 104. When the nuts enter the shell crushing box 101, they are divided into two batches by the dividing plate 105 and enter the shell crushing box 101 to avoid overloading caused by too many nuts processed by a single group of shell crushing rollers 103. An adjusting block 106 is slidably provided on the dividing plate 105. A feeding roller 107 is slidably provided on the adjusting block 106. When the nuts enter the shell crushing roller 103, some nuts accumulate on the shell crushing roller 103 and do not enter the groove. The feeding roller 107 is driven to adjust the adjusting block 106. The material-dispensing roller 107 slides up, and the material-dispensing roller 107 is close to the shell-breaking roller 103, driving the adjusting block 106 to slide back and forth on the dividing plate 105. The material-dispensing roller 107 moves the nuts on the shell-breaking roller 103, thereby improving the uniformity of the distribution of the nuts on the shell-breaking roller 103, and improving the shell-breaking efficiency of the shell-breaking roller 103 and the shell-breaking frame 102. Two groups of adjusting blocks 110 are slidingly arranged on the upper end of the shell-breaking box 101, and a mounting frame 111 is slidingly arranged on the adjusting block 110. A connecting rod 112 is rotatably arranged on the mounting frame 111. One end of the connecting rod 112 is rotatably connected to the mounting frame 111, and a connecting rod 2 113 is rotatably arranged on the other end of the connecting rod 112. It is rotatably connected with the connecting rod 112, and the other end of the connecting rod 2 113 is rotatably provided with a dredging roller 114. The connecting rod 112 and the connecting rod 2 113 are driven to rotate to adjust the position of the dredging roller 114. At the same time, the adjusting block 3 110 and the mounting frame 111 are driven to move, and the dredging roller 114 is placed at the blocked position. The dredging roller 114 is driven to rotate, and the dredging roller 114 dredges the blocked position. Two groups of anti-blocking plates 115 are rotatably provided at the lower end of the crushing shell box 101. A torsion spring is provided between the anti-blocking plate 115 and the rotating shaft of the crushing shell box 101. An anti-blocking frame 116 is slidably provided inside the anti-blocking plate 115. A plurality of groups of dredging columns 117 are rotatably provided inside the anti-blocking frame 116.A first cam 118 is rotatably arranged on the shell-breaking box 101. The first cam 118 is in contact with the anti-blocking plate 115. When driving the first cam 118 to rotate, the first cam 118 drives the anti-blocking plate 115 to swing reciprocally on the shell-breaking box 101, drives the anti-blocking frame 116 to slide in the anti-blocking plate 115, the anti-blocking frame 116 drives the dredging column 117 to extend out, drives the dredging column 117 to rotate on the anti-blocking frame 116. After the dredging column 117 rotates out, it faces the blocked position. Driving the first cam 118 to rotate, the first cam 118 drives the anti-blocking plate 115 to swing, and the anti-blocking plate 115 drives the dredging column 117 to swing to achieve dredging of the blocked position.

[0030] The feeding assembly 2 includes a feeding cylinder 201 installed at the upper end of the shell-breaking box 101. A dust-removing chamber 203 is arranged on the feeding cylinder 201. Multiple air extraction openings 204 are arranged on the dust-removing chamber 203. When nuts are put in, driving the air extraction openings 204 to work, the air extraction openings 204 extract the air in the dust-removing chamber 203 and the feeding cylinder 201, and the dust generated when the nuts are put in is sucked out, preventing dust and sundries from entering the shell-breaking box 101. A blanking cylinder 202 and a blanking plate 206 are slidably arranged at the upper end of the feeding cylinder 201. A first spring 207 is arranged between the blanking plate 206 and the feeding cylinder 201. A second cam 208 is rotatably arranged on the feeding cylinder 201. The second cam 208 is in contact with the blanking plate 206. When driving the second cam 208 to rotate, the second cam 208 drives the blanking plate 206 to slide reciprocally on the feeding cylinder 201. Nuts fall onto the blanking plate 206 through the blanking cylinder 202. At this time, the blanking plate 206 shakes, slowing down the falling speed of the nuts and preventing excessive accumulation of nuts in the shell-breaking box 101. Multiple adjusting blocks four 209 are slidably arranged in the feeding cylinder 201. A stirring frame 210 is rotatably arranged on the adjusting blocks four 209. Driving the stirring frame 210 to rotate, the stirring frame 210 stirs the nuts to prevent blockage. A pushing plate 205 is also slidably arranged inside the feeding cylinder 201. Multiple pushing plates 205 block the nuts, slowing down the falling speed of the nuts. Multiple baffle plates 211 are rotatably arranged at the lower end of the feeding cylinder 201. The baffle plates 211 close the feeding cylinder 201, and the nuts enter the shell-breaking box 101 through the feeding cylinder 201 for crushing.

[0031] The separation component 3 includes a screening box 301 installed on the side of the shell-breaking box 101. A screening plate 302 is slidably arranged in the screening box 301. A second spring 306 is arranged between the screening plate 302 and the screening box 301. A third cam 304 is rotatably arranged on the screening box 301. The third cam 304 is in contact with the screening plate 302. When driving the third cam 304 to rotate, the third cam 304 drives the screening plate 302 to slide back and forth on the screening box 301. The nuts after shell-breaking fall on the screening plate 302. There is a difference in weight between the outer shell and the kernel. The outer shell is lifted by the shaking of the screening plate 302. An air separation port 305 is arranged on the side of the screening box 301. The air separation port 305 blows air on the outer shell on the screening plate 302 to blow the outer shell into the recycling box 303. The recycling box 303 is installed on the side of the screening box 301. A crushing plate 307 is slidably arranged at the connection between the recycling box 303 and the screening box 301. A baffle plate 308 is arranged on the side of the recycling box 303 to prevent the outer shell from flying out of the recycling box 303 too fast. A discharging plate 311 is rotatably arranged at the lower end of the recycling box 303. When the discharging plate 311 is in contact with the baffle plate 308, the recycling box 303 is closed. An adjusting block five 309 is slidably arranged at the upper end of the recycling box 303. An adjusting frame 310 is rotatably arranged at the lower end of the adjusting block five 309. Two groups of clamping frames 312 are slidably arranged in the adjusting frame 310. When the two groups of clamping frames 312 approach each other, the outer shell is clamped. Multiple groups of dredging rollers two 313 are slidably arranged on the adjusting frame 310. The dredging rollers two 313 dredge the blocked positions.

[0032] Working principle: During operation, pour the nuts into the feeding cylinder 202. At the same time, drive the second cam 208 to rotate. The second cam 208 drives the feeding plate 206 to slide back and forth on the feeding cylinder 201. When the nuts fall on the feeding plate 206 through the feeding cylinder 202, due to the vibration of the feeding plate 206, the falling speed of the nuts on the feeding plate 206 is slowed down. Since different nuts have different weights, drive the feeding cylinder 202 to slide on the feeding cylinder 201 to change the distance between the feeding cylinder 202 and the feeding cylinder 201, and change the falling speed of the nuts on the feeding plate 206. The nuts falling from the feeding plate 206 pass through the dust-removing chamber 203 and fall into the feeding cylinder 201. Drive the air extraction port 204 to work. The air extraction port 204 extracts the air in the feeding cylinder 201 through the dust-removing chamber 203. The air in the feeding cylinder 201 and the sundries on the nuts are sucked out at the same time to prevent dust from being put into the shell-breaking component 1. When the lower end of the feeding cylinder 201 is blocked, drive the adjusting block four 209 to rotate in the feeding cylinder 201. At the same time, drive the stirring frame 210 to rotate. The stirring frame 210 stirs the nuts in the feeding cylinder 201. At the same time, drive the pushing plate 205 to slide on the feeding cylinder 201. The pushing plate 205 pushes the nuts and slows down the falling speed of the nuts. When the feeding cylinder 201 feeds materials into the shell-breaking box 101, drive the baffle plate 211 to rotate on the feeding cylinder 201. The baffle plate 211 releases the closure of the feeding cylinder 201.

[0033] After the nuts are discharged from the feeding cylinder 201, they are divided into two batches by the material distribution plate 105 and enter the shell-breaking box 101. The nuts fall on the shell-breaking roller 103. The driving feeding roller 107 slides on the first adjusting block 106. The feeding roller 107 approaches the shell-breaking roller 103. After the feeding roller 107 fits with the nuts, it drives the first adjusting block 106 to slide in the shell-breaking box 101. The first adjusting block 106 drives the feeding roller 107 to slide back and forth, and the feeding roller 107 spreads out the nuts piled up on the shell-breaking roller 103 to prevent the nuts from piling up and affecting the efficiency of nut shell-breaking. The driving shell-breaking frame 102 moves on the shell-breaking box 101 to adjust the distance between the shell-breaking frame 102 and the shell-breaking roller 103. Subsequently, the shell-breaking roller 103 is driven to rotate. The shell-breaking roller 103 drives the nuts to be squeezed with the shell-breaking frame 102 to achieve nut shell-breaking. After the nuts are shell-broken, they fall on the feeding cylinder 201 at the lower end of the shell-breaking box 101. The driving second adjusting block 108 slides in the shell-breaking box 101. The second adjusting block 108 drives the cleaning roller 109 to fit with the shell-breaking roller 103. The cleaning roller 109 is driven to rotate, and the cleaning roller 109 cleans the shell-breaking roller 103 to prevent nut shells from remaining on the shell-breaking roller 103.

[0034] When a blockage occurs between the shell-breaking frame 102 and the shell-breaking roller 103, if the blockage occurs in the direction of the feeding port 104 between the shell-breaking frame 102 and the shell-breaking roller 103, the first connecting rod 112 and the second connecting rod 113 are driven to rotate. The second connecting rod 113 drives the first dredging roller 114 to move. The third adjusting block 110 and the first mounting frame 111 are driven to move. The first mounting frame 111 drives the first dredging roller 114 to reach the blocked position. The first dredging roller 114 is driven to rotate, and the first dredging roller 114 cleans the blocked position.

[0035] If the blockage occurs in the direction of the screening plate 302 between the shell-breaking frame 102 and the shell-breaking roller 103, the anti-blocking frame 116 is driven to slide in the anti-blocking plate 115. The anti-blocking frame 116 drives the dredging column 117 to extend out of the anti-blocking plate 115. The dredging column 117 is driven to rotate on the anti-blocking frame 116. After the dredging column 117 faces the blocked position, the first cam 118 is driven to rotate. The first cam 118 drives the anti-blocking plate 115 to swing on the shell-breaking box 101. The anti-blocking plate 115 drives the dredging column 117 to dredge the blocked position.

[0036] After the nutshells are cracked, they fall onto the screening plate 302. The third driving cam 304 rotates, driving the screening plate 302 to shake. At the same time, the air separation port 305 is driven to work to complete the separation of the nut shells and kernels. The separated outer shells enter the recycling box 303, and the outer shells are blown onto the baffle plate 308 to be blocked, preventing the outer shells from being blown out of the recycling box 303. The discharging plate 311 is driven to rotate. When the discharging plate 311 is in contact with the baffle plate 308, the recycling box 303 is closed. When it is necessary to take out the outer shells in the recycling box 303, the discharging plate 311 is driven to rotate, and the discharging plate 311 releases the closure of the recycling box 303 to take out the outer shells. When the connection between the screening box 301 and the recycling box 303 is blocked, the crushing plate 307 is driven to slide on the recycling box 303, and the crushing plate 307 presses the outer shells blocked at the connection. When there are relatively large outer shells at the connection that cannot be squeezed, the adjusting frame 310 is driven to rotate on the fifth adjusting block 309. The adjusting frame 310 drives the clamping frame 312 and the second dredging roller 313 to move, adjusting the positions of the clamping frame 312 and the second dredging roller 313. The fifth adjusting block 309 is driven to move, and the fifth adjusting block 309 drives the clamping frame 312 to approach the blocked position. When the clamping frames 312 are driven to approach each other, the relatively large outer shells are taken out, and the second dredging roller 313 is driven to rotate to dredge the blocked position.
