Description

Technical Field

[0001] The invention relates to the technical field of nut shelling, and in particular to a nut shelling machine with an anti-blocking function. Background Art

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

A cam 208 is rotatably arranged on the feeding barrel 201, and the cam 208 is in contact with the discharge plate 206. When the cam 208 is driven to rotate, the cam 208 drives the discharge plate 206 to rotate in the feeding barrel. The barrel 201 slides back and forth, and the nuts fall onto the discharge plate 206 through the discharge barrel 202. At this time, the discharge plate 206 shakes to slow down the falling speed of the nuts and avoid excessive accumulation of nuts in the shell crushing box 101. Multiple groups of adjusting blocks 209 are slidingly arranged in the feed barrel 201. A turning rack 210 is rotatably arranged on the adjusting block 209 to drive the turning rack 210 to rotate. The turning rack 210 turns the nuts to avoid blockage caused by the nuts. A pushing plate 205 is also slidingly arranged inside the feed barrel 201. Multiple groups of pushing plates 205 block the nuts and slow down the falling speed of the nuts. Multiple groups of baffles 211 are rotatably arranged at the lower end of the feed barrel 201. The baffle 211 closes the feed barrel 201, and the nuts enter the shell crushing box 101 through the feed barrel 201 for crushing.

[0031] The separation component 3 includes a screening box 301 installed on the side of the shell crushing box 101, a screening plate 302 is slidably arranged in the screening box 301, a spring 2 306 is arranged between the screening plate 302 and the screening box 301, a cam 304 is rotatably arranged on the screening box 301, the cam 304 is in contact with the screening plate 302, when the cam 304 is driven to rotate, the cam 304 drives the screening plate 302 to slide back and forth on the screening box 301, and the shelled nuts fall on the screening plate 302, there is a weight difference between the shell and the kernel, and the shell is lifted by the shaking of the screening plate 302, and an air selection port 305 is arranged on the side of the screening box 301, and the air selection port 305 blows the shell on the screening plate 302, and blows the shell into the recycling box 303, and the recycling box 3 03 is installed on the side of the screening box 301, and a particle board 307 is slidably provided at the connection between the recovery box 303 and the screening box 301. A baffle plate 308 is provided on the side of the recovery box 303 to prevent the shell from flying out of the recovery box 303 at too fast a speed. A discharge plate 311 is rotatably provided at the lower end of the recovery box 303. When the discharge plate 311 and the baffle plate 308 are in contact, the recovery box 303 is closed. An adjusting block 5 309 is slidably provided at the upper end of the recovery box 303. An adjusting frame 310 is rotatably provided at the lower end of the adjusting block 5 309. Two groups of clamping frames 312 are slidably provided in the adjusting frame 310. When the two groups of clamping frames 312 are close to each other, the shell is clamped. A plurality of groups of dredging rollers 313 are slidably provided on the adjusting frame 310, and the dredging rollers 313 dredge the blocked position.

[0032] Working principle: During operation, the nuts are poured into the discharge barrel 202, and the cam 208 is driven to rotate at the same time. The cam 208 drives the discharge plate 206 to slide back and forth on the feed barrel 201. When the nuts pass through the discharge barrel 202 and fall onto the discharge plate 206, the discharge plate 206 vibrates, slowing down the falling speed of the nuts on the discharge plate 206. Due to the different weights of different nuts, the discharge barrel 202 is driven to slide on the feed barrel 201, changing the distance between the discharge barrel 202 and the feed barrel 201, changing the speed at which the nuts fall onto the discharge plate 206, and the nuts falling from the discharge plate 206 pass through the dust cleaning chamber 203 and fall into the feed barrel 201, driving the exhaust port 204 to work, and the exhaust port 204 will extract the air in the feed barrel 201 through the dust cleaning chamber 203, and the air in the feed barrel 201 and the debris on the nuts will be sucked out at the same time to prevent dust from being thrown into the shell crushing assembly 1. When the lower end of the feed barrel 201 is blocked, the adjustment block 209 will be driven to rotate in the feed barrel 201, and the turning frame 210 will be driven to rotate. The turning frame 210 will turn the nuts in the feed barrel 201 and drive the push plate 205 to slide on the feed barrel 201. The push plate 205 pushes the nuts and slows down the falling speed of the nuts. When the feed barrel 201 feeds into the shell crushing box 101, the baffle 211 will be driven to rotate on the feed barrel 201, and the baffle 211 will release the seal on the feed barrel 201.

[0033] After the nuts enter and are discharged from the feed barrel 201, they are divided into two batches by the dividing plate 105 and enter the shell crushing box 101. The nuts fall on the shell crushing roller 103, driving the feeding roller 107 to slide on the adjusting block 106. The feeding roller 107 approaches the shell crushing roller 103. After the feeding roller 107 is fitted with the nuts, the adjusting block 106 is driven to slide in the shell crushing box 101. The adjusting block 106 drives the feeding roller 107 to slide back and forth. The feeding roller 107 spreads the nuts accumulated on the shell crushing roller 103 to avoid the nuts piling up and affecting the efficiency of nut shelling. The shell crushing frame 10 2 moves on the shell crushing box 101, adjusts the distance between the shell crushing frame 102 and the shell crushing roller 103, and then drives the shell crushing roller 103 to rotate, and the shell crushing roller 103 drives the nuts to be squeezed with the shell crushing frame 102 to realize the shelling of the nuts. After the nuts are shelled, they fall onto the feeding tube 201 through the lower end of the shell crushing box 101, and the regulating block 2 108 is driven to slide in the shell crushing box 101. The regulating block 2 108 drives the cleaning roller 109 to fit with the shell crushing roller 103, and drives the cleaning roller 109 to rotate. The cleaning roller 109 cleans the shell crushing roller 103 to avoid the nut shells remaining on the shell crushing roller 103.

[0034] When a blockage occurs between the shell crushing frame 102 and the shell crushing roller 103, if the shell crushing frame 102 and the shell crushing roller 103 are blocked in the direction of the feed port 104, the connecting rod 112 and the connecting rod 2 113 are driven to rotate, the connecting rod 2 113 drives the dredging roller 114 to move, the adjusting block 3 110 and the mounting frame 111 are driven to move, the mounting frame 111 drives the dredging roller 114 to reach the blocked position, the dredging roller 114 is driven to rotate, and the dredging roller 114 cleans the blocked position.

[0035] If the shell crushing frame 102 and the shell crushing roller 103 are blocked in the direction of the screening plate 302, the anti-blocking frame 116 is driven to slide in the anti-blocking plate 115, and the anti-blocking frame 116 drives the dredging column 117 to extend out from the anti-blocking plate 115, and the dredging column 117 is driven to rotate on the anti-blocking frame 116. After the dredging column 117 moves toward the blocked position, the cam 118 is driven to rotate, and the cam 118 drives the anti-blocking plate 115 to swing on the shell crushing box 101, and the anti-blocking plate 115 drives the dredging column 117 to dredge the blocked position.

[0036] After the nuts are shelled, they fall onto the screening plate 302, driving the cam 304 to rotate, which drives the screening plate 302 to shake, and at the same time drives the air selection port 305 to separate the shells and kernels of the nuts. The separated shells enter the recycling box 303, and are blown onto the baffle plate 308 to block, so as to prevent the shells from being blown out of the recycling box 303. The discharge plate 311 is driven to rotate, and the discharge plate 311 and the baffle plate 308 are fitted to close the recycling box 303. When the shells in the recycling box 303 need to be taken out, the discharge plate 311 is driven to rotate, and the discharge plate 311 releases the closure of the recycling box 303 to take out the shells. When a blockage occurs at the connection between 01 and the recycling box 303, the particle board 307 is driven to slide on the recycling box 303, and the particle board 307 presses the shell blocked at the connection. When there is a larger shell that cannot be squeezed at the connection, the adjustment frame 310 is driven to rotate on the adjustment block five 309, and the adjustment frame 310 drives the clamping frame 312 and the dredging roller two 313 to move, and adjusts the positions of the clamping frame 312 and the dredging roller two 313, and drives the adjustment block five 309 to move, and the adjustment block five 309 drives the clamping frame 312 to approach the blocked position, and when the clamping frames 312 are driven to approach each other, the larger shell is taken out, and the dredging roller two 313 is driven to rotate to dredge the blocked position.
