The side of the second push rod fixing seat 9-5 is provided with screw holes 10-1. After the screw holes 10-1 coincide with the fixing seat connection holes 9-1-2 on the side of the motor end 9-2, screws 10-1 are inserted for installation.

When the first clamping element 9-13 is installed, the first fixing block 9-6 connects to the first clamping element 9-13 from the clamping element mounting end 9-13-4. The first clamping element 9-13 and the second clamping element 9-14 have the same structure. When the second clamping element 9-14 is installed, the second fixing block 9-7 connects to the first clamping element 9-13 from the clamping element mounting end 9-13-4 of the second clamping element 9-14. The first clamping element 9-13 and the second clamping element 9-14 have the same structure. Figure 11As shown, after installation, the first clamping part 9-13 and the second clamping part 9-14 are positioned opposite each other. The shape inside the two slots is the same as the shape of a walnut 17 after the components inside the slots are installed. Before the shelling operation of the walnut 17, the walnuts 17 are screened according to size. Multiple sets of clamping parts are set according to the specifications of the walnuts 17. Matching clamps are set according to the specifications of the walnuts 17. The corresponding clamping parts are matched with the walnuts 17 according to the actual production situation to ensure the shelling effect of the walnuts.

The lower push rod insertion holes 9-13-5 are located below the first clamping member 9-14. 13. One side of the second clamping member 9-14 extends to the other side of the first clamping member 9-13. The fixed end push rod 9-9 and the motor end push rod 9-10 are inserted into the lower push rod insertion hole 9-13-4. The upper push body of the fixed end push rod 9-9 and the motor end push rod 9-10 is inserted into the upper push rod insertion hole 9-13-8 of the groove of the first clamping member 9-13 and the second clamping member 9-14. During installation, the motor end push rod is inserted into the upper push rod insertion hole 9-13-8 of the second clamping member 9-13.

[0029] The walnut shelling machine is assembled using screws, facilitating installation, fixation, disassembly, and maintenance. During shelling, the feeder 3 delivers walnuts that meet the placement requirements, and the bracket 16 forms a placement rack 8. The placement rack 8 corresponds to the clamping mechanism 9. After the walnuts are delivered, the first clamping member 9-13 and the second clamping member 9-14 clamp the walnut 17. When clamping the walnut, the meshing saw teeth 9-13-6 of the first clamping member 9-13 and the second clamping member 9-14 engage, fixing the walnut 17 in a position where the outer ridge edge 17-1 faces upwards and downwards. Simultaneously, the cutting blade 9-13-7 cuts the walnut open from the side 17-2, and the extrusion shaft 9-13-2 aligns with the kernel. The walnuts are squeezed, and the squeezing position of walnut 17 is aligned with the growth structure of the walnut kernel. Squeezing is performed from the shell of walnut 17 to the gap of the walnut kernel. The squeezing process is to keep the walnut kernel intact as much as possible and avoid violent squeezing that will break the walnut kernel. During the squeezing process, the upper push rod and the lower push rod of the fixed end push rod 9-9 and the motor end push rod 9-10 move within the range of the fixed end push rod 9-9 and the motor end push rod 9-10. The upper push rod in the slot can be slid to squeeze out the shelled walnut. The squeezed walnut 17 falls back onto the chain plate 15 of the feeder 3. The feeder 3 continues to move to send out the shelled walnut kernel, which is discharged from the discharge bin 5 and discharged through the discharge guide plate 6 for recycling.

[0030] Take 3 kg of walnut kernels processed using the described walnut shelling method. Sift the kernels through a sieve to separate broken kernels, second-grade kernels, and first-grade kernels. The broken kernels are as follows: Figure 15 As shown, grade two walnut kernels are as follows: Figure 16 As shown, grade two walnut kernels are as follows: Figure 17 As shown, the crushed walnut kernels were weighed, with the weight of the crushed and second-grade walnut kernels being 0.6 kg, and the weight of the first-grade walnut kernels being 2.4 kg. Based on the weight of the crushed and first-grade walnut kernels, the first-grade rate of the shelled walnut kernels was calculated. The weight ratio of first-grade walnut kernels in 3 kg of shelled walnut kernels was 80%. Therefore, the walnut shelling method described uses a walnut shelling machine. A chain plate feeder feeds the walnuts into the walnut shelling device. The walnuts are positioned on the top surface of the placement rack placed in the feeder, and the outer spine of the walnuts is adjusted to face upwards. After the walnuts are positioned, they are fed into the walnut shelling machine by the feeder. After shelling, the walnut kernels are collected. The first-grade rate of the shelled walnut kernels is 80%.
