Description
Technical Field
[0001] This application relates to the technical field of nut shelling, and more specifically, to a pine nut shelling device. Background Art
[0002] Pine nuts are rich in nutrients such as fat, protein, and vitamins. Their excellent quality is characterized by a thin shell, fragrant meat, and large size. They can supplement energy, enhance resistance, and also have beauty benefits. With the improvement of people's living standards, the demand for pine nuts has been increasing, leading to an expansion of the global pine nut planting scale.
[0003] Currently, commonly used pine nut shelling devices usually have a pair of relatively rotating rolling rollers to crush the hard shell of pine nuts. However, due to the relatively hard shell of pine nuts, the rolling rollers are likely to crush the kernels while breaking the shell, resulting in a poor actual shelling effect. Summary of the Utility Model
[0004] The purpose of this utility model is to provide a pine nut shelling device that can reduce damage to the internal kernels while breaking the outer shell of pine nuts.
[0005] The embodiment of this utility model is achieved by the following technical solutions: A pine nut shelling device includes a frame, a feed hopper, and a shelling mechanism. The shelling mechanism is installed above the frame, and the feed hopper is located above the shelling mechanism.
[0006] The shelling mechanism includes an arc-shaped extrusion shell, a rotating motor, a rotating roller, and a rolling roller. The rotating roller is arranged at the output end of the rotating motor. A plurality of accommodation holes for accommodating pine nuts are formed on the surface of the rotating roller. The depth of the accommodation holes is less than half of the average width of pine nuts. The rotating roller and the arc-shaped extrusion shell respectively abut on both sides of the pine nuts. A plurality of groups of cutting knife assemblies are arranged on the side of the arc-shaped extrusion shell facing the rotating roller. The cutting knife assemblies are used to scratch the outer shell of the pine nuts located in the accommodation holes. The rolling roller is located below the rotating roller. The rolling roller is connected to the output end of the rotating motor through a belt. A rolling plate is arranged at the discharging end of the arc-shaped extrusion shell. The rolling roller rolls and abuts on the rolling plate.
[0007] Further, the cutting knife assembly includes a first cutting knife. The first cutting knife is perpendicular to the axis of the rotating roller, and the first cutting knife is located in the plane where the center of the accommodation hole rotates.
[0008] Further, the cutting knife assembly further includes a second cutting knife. The second cutting knife is parallel to the axis of the rotating roller. A parallel driver is arranged on the arc-shaped extrusion shell. The parallel driver drives the second cutting knife to move along a direction parallel to the axis of the rotating roller.
[0009] Furthermore, the cutter assembly further includes a third cutter, and the third cutter is located in the plane where the two ends of the accommodating hole rotate.
[0010] Furthermore, an auxiliary cutter is arranged in the accommodating hole, and the auxiliary cutter abuts against the outer shell of the pine nut on the side facing the accommodating hole.
[0011] Furthermore, the inside of the rolling roller is hollow, and a hammering weight is arranged to roll inside the rolling roller.
[0012] Furthermore, a plurality of partition plates are convexly arranged on the inner wall of the rolling roller, the partition plates extend along the axial direction of the rolling roller, and the hammering weight abuts against the surface of the partition plates.
[0013] Furthermore, a plurality of raised strips are arranged on the surface of the rolling roller.
[0014] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects:
[0015] 1. In the present utility model, first, during the process of the pine nut passing through the arc-shaped extrusion shell, the cutter assembly is used to scratch the outer shell of the pine nut, so that scratches are generated on the outer shell of the pine nut, thereby destroying the integrity of the outer shell of the pine nut, so that when the rolling roller is used to roll the pine nut later, the rolling roller can separate the outer shell and the kernel with a smaller pressure.
[0016] 2. The present utility model can scratch intersecting scratches on the surface of the outer shell of the pine nut by arranging a plurality of cutters facing different directions, destroying the connection between the outer shells, and making it easier to separate the outer shell fragments.
[0017] 3. In the rolling roller of the present utility model, a hammering weight is used. During the rotation of the rolling roller, the hammering weight falls from a high place inside the rolling roller and impacts the side wall of the rolling roller, increasing the pressure of the rolling roller on the outer shell of the pine nut and more quickly breaking the outer shell of the pine nut.

[0027] Embodiment
[0028] The following is further described with specific embodiments. Refer to Figures 1 - 5 As shown, the present utility model is a pine nut shell-breaking device, including a frame 100. A feed hopper 110 and a shell-breaking mechanism are installed at the top of the frame 100. The feed hopper 110 is located above the shell-breaking mechanism.
[0029] Refer to Figure 2, the shell-breaking mechanism includes an arc-shaped extrusion shell 120, a rotating motor, a rotating roller 130, and a rolling roller 140. The arc-shaped extrusion shell 120 and the rotating motor are fixedly installed on the frame 100, and the arc-shaped extrusion shell 120 faces the side of the rotating roller 130. The rotating roller 130 and the rolling roller 140 are rotatably installed on the frame 100. The axes of the rotating roller 130 and the rolling roller 140 are both distributed in the horizontal direction, and the axes of the rotating roller 130 and the rolling roller 140 are parallel to the output end of the rotating motor. The output end of the rotating motor is respectively connected to the ends of the rotating roller 130 and the rolling roller 140 through belts to drive the rotating roller 130 and the rolling roller 140 to rotate.
[0030] Refer to Figure 3 , the bottom end of the feed hopper 110 is located at the top of the rotating roller 130. A plurality of accommodation holes 131 for accommodating fixed pine nuts are provided on the side surface of the rotating roller 130. The length of the accommodation holes 131 is adapted to the average length of the pine nuts, and the depth of the accommodation holes 131 is less than half of the average width of the pine nuts. Auxiliary cutting blades 132 are provided on the inner wall of the accommodation holes 131. The auxiliary cutting blades 132 include axial cutting blades and radial cutting blades. The axial cutting blades are along the direction parallel to the axis of the rotating roller 130, and the radial cutting blades are along the direction parallel to the plane where the diameter of the rotating roller 130 is located. And the axial cutting blades intersect with the radial cutting blades and abut against the outer shell surface of the pine nuts on the side facing the accommodation holes 131.
[0031] Refer to Figure 4 , the top end of the arc-shaped extrusion shell 120 is the first end, and the bottom end of the arc-shaped extrusion shell 120 is the second end. A gap is reserved between the arc-shaped extrusion shell 120 and the rotating roller 130. The side of the pine nut facing away from the rotating roller 130 abuts against the inner wall of the arc-shaped extrusion shell 120. A plurality of groups of cutting blade assemblies are provided on the side of the arc-shaped extrusion shell 120 facing the gap. Among them, the cutting blade assembly includes a first cutting blade 121, a second cutting blade 122, and a third cutting blade 123. The first cutting blade 121 is close to the first end of the arc-shaped extrusion shell 120. The first cutting blade 121 is along the direction parallel to the radial plane of the rotating roller 130, and the first cutting blade 121 is located in the plane where the center of the accommodation hole 131 moves. When the rotating roller 130 drives the pine nut to pass by the first cutting blade 121, the first cutting blade 121 is aligned with the center of the accommodation hole 131, and a scratch is cut out at the middle position of the outer shell of the pine nut in the accommodation hole 131.
[0032] Refer to Figure 2 and Figure 4, the second cutting knife 122 is located below the first cutting knife 121, and the second cutting knife 122 is located between the first end and the second end of the arc-shaped extrusion shell 120. The tip of the second cutting knife 122 is perpendicular to the axis of the rotating roller 130 and the second cutting knife 122 moves along a direction parallel to the axis of the rotating roller 130. The shape of the second cutting knife 122 is needle-shaped. A parallel driver 124 is provided on the surface of the arc-shaped extrusion shell 120. The parallel driver 124 is along a direction parallel to the axis of the rotating roller 130, and the second cutting knife 122 is arranged at the output end of the parallel driver 124 so that the parallel driver 124 drives the second cutting knife 122 to move along the axis direction of the rotating roller 130. When the pine nut rotates to the position of the second cutting knife 122 along with the rotating roller 130, due to the parallel driver 124 driving the second cutting knife 122 to move horizontally and the rotating roller 130 driving the pine nut to rotate around the center of the rotating roller 130, when the second cutting knife 122 abuts against the surface of the pine nut shell, the second cutting knife 122 scratches an inclined scratch on the pine nut shell. In this embodiment, the parallel driver 124 is a cylinder, and the second cutting knife 122 is arranged at the end of the piston rod of the cylinder.
[0033] In one embodiment, the parallel driver is a linear motor. The stator of the linear motor is arranged on the arc-shaped extrusion shell, and the second cutting knife is arranged on the mover of the linear motor.
[0034] Refer to Figure 4 , the third cutting knife 123 is located below the second cutting knife 122. The third cutting knife 123 is close to the second end of the arc-shaped extrusion shell 120, and the third cutting knife 123 has the same orientation as the first cutting knife 121. There are two third cutting knives 123 in each group, and the two third cutting knives 123 are respectively located in the plane where the two ends of each accommodation hole 131 rotate around the center of the rotating roller 130. So that when the pine nut passes through the third cutting knife 123, the two third cutting knives 123 respectively cut and scratch the two ends of the pine nut, thereby cutting open the two ends of the pine nut shell.
[0035] Refer to Figure 4 , a rolling plate 125 is provided at the second end of the arc-shaped extrusion shell 120. The pine nut slides onto the surface of the rolling plate 125 after being cut by the cutting knife assembly. The rolling plate 125 is inclined gradually towards the ground from one end connected to the arc-shaped extrusion shell 120 to the end far from the arc-shaped extrusion shell 120. The rolling roller 140 abuts against the surface of the rolling plate 125. A plurality of protruding strips 141 are provided on the surface of the rolling roller 140, and the material of the protruding strips 141 is an elastic material.
[0036] Refer to Figure 5, the interior of the rolling roller 140 is hollow, and a plurality of partition plates 142 are arranged inside the rolling roller 140. The plurality of partition plates 142 all protrude from the inner wall of the rolling roller 140, and there are gaps between the ends of the partition plates 142 away from the rolling roller 140. The plurality of partition plates 142 divide the inner surface of the rolling roller 140 into a plurality of partition chambers, and the plurality of partition chambers are symmetrically distributed relative to the center of the rolling roller 140. A hammer weight 143 is placed inside the rolling roller 140, and the width of the hammer weight 143 is smaller than the distance between adjacent partition plates 142. During the rotation of the rolling roller 140, the partition plate 142 raises the height of the hammer weight 143 through the partition plate 142, and then the vertical weight falls under the action of gravity and impacts the inner wall of the rolling roller 140, increasing the pressure between the rolling roller 140 and the pine nut shell.
[0037] Referring to Figure 1 , an output slide plate 150 and a screening slide plate 160 are further installed on the frame 100. The output slide plate 150 and the screening slide plate 160 are both located below the rolling plate 125. The output slide plate 150 and the screening slide plate 160 are arranged in parallel. The first ends of the output slide plate 150 and the screening slide plate 160 are located below the rolling plate 125, and the second ends of the output slide plate 150 and the screening slide plate 160 are inclined towards the ground. Leakage holes 161 are formed on the surface of the screening slide plate 160.
[0038] The working process of this embodiment is as follows: When cracking pine nuts, the pine nuts are put into the cracking device from the feed hopper 110. The pine nuts fall into the accommodation holes 131 and move along the first end of the arc-shaped extrusion shell 120 towards the second end under the rotation of the rotating roller 130. When the rotating roller 130 drives the pine nuts past the first cutting knife 121, the first cutting knife 121 cuts the pine nut shell along the width direction of the pine nut. When the rotating roller 130 drives the pine nuts past the second cutting knife 122, the second cutting knife 122 moves along the axis direction of the rotating roller 130 under the action of the parallel driver 124, and at the same time, under the combined action of the rotating force of the rotating roller 130, inclined scratches are made on the outer shell of the pine nuts. When the rotating roller 130 drives the pine nuts past the third cutting knife 123, the third cutting knife 123 cuts the two ends of the pine nuts respectively. And during the whole process, the first cutting knife 121, the second cutting knife 122 and the third cutting knife 123 squeeze the pine nuts to make the pine nuts press against the auxiliary cutting knife 132 in the accommodation hole 131, and cut on the surface of the pine nuts facing the accommodation hole 131 side, so that scratches are distributed on both sides of the outer shell.
[0039] When the pine nuts move to the second end of the arc-shaped extrusion shell 120, the pine nuts fall onto the rolling plate 125 under the action of gravity, and the rolling roller 140 rolls the pine nuts on the rolling plate 125 to crush the damaged outer shell.
[0040] Finally, the pine nuts fall onto the screening slide plate 160, and the broken shell fragments fall onto the output slide plate 150 through the leakage holes 161, realizing the separation of the kernels from the shells. The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
