[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In the embodiments, by Figure 1-5 A complete acorn shelling production line is provided, comprising a support frame 1, a shelling cover 2 fixedly connected to the inner side of the support frame 1, the bottom end of the shelling cover 2 being open, a feed hopper 3 fixedly connected to the top end of the shelling cover 2, and a plurality of discharge rollers 4 fixedly connected to the bottom end of the shelling cover 2, with discharge gaps 5 formed between the plurality of discharge rollers 4, a shelling mechanism 6 provided on the inner side of the shelling cover 2, a screening mechanism 7 located below the shelling cover 2 provided on the inner side of the support frame 1, and a drive mechanism 8 provided on the support frame 1 for driving the shelling mechanism 6 and the screening mechanism 7.
[0023] With the above setup, acorns enter the shelling hood 2 through the feed hopper 3. First, the shelling mechanism 6 scratches and breaks the acorn shells, reducing the overall structural strength and facilitating subsequent shelling. The processed acorns fall into the discharge gap 5, composed of multiple discharge rollers 4. The drive mechanism 8 drives the shelling mechanism 6 to rotate at high speed. Within the discharge gap 5, the acorns are subjected to compression, impact, and friction, further breaking down the shells and separating them from the kernels. The shelled mixture falls to the screening mechanism 7 for screening, separating intact kernels, which are then output through the material handling channel (not shown in the figure). Broken kernels and small particles are screened out and collected through the crushed material channel (not shown in the figure). If a small amount of shell is mixed with the kernels or kernels are mixed with the crushed material, it can be manually removed. The drive mechanism 8 can simultaneously drive the shelling mechanism 6 and the screening mechanism 7, integrating the shelling and screening processes, reducing labor costs and saving floor space.
[0024] Reference Figure 1-5The shelling mechanism 6 includes a shelling shaft 61. Two shelling shafts 61 are rotatably connected to the inner side of the shelling cover 2. Two shelling rollers 62 are fixedly connected to the outer side of each of the two shelling shafts 61. Several protrusions 63 are fixedly connected to the outer side of each of the two shelling rollers 62.
[0025] With the above structural arrangement, after the acorns enter the shelling hood 2 from the feed hopper 3, they fall into the working area between two parallel shelling shafts 61. The shelling shafts 61 are driven by the drive mechanism 8 and rotate in opposite directions. The protrusions 63 (such as toothed or wedge-shaped structures) on the surface of the shelling rollers 62 first come into contact with the acorns. The impact force generated by the high-speed rotation forms initial cracks or scratches on the acorn shell, damaging the integrity of the shell. This step is similar to "pre-breaking," reducing the structural strength of the shell and creating conditions for subsequent extrusion and shelling. The acorns are carried into the wedge-shaped gap between the two shelling rollers 62 as the shelling rollers 62 rotate. Since the distance between the two shelling rollers 62 is smaller than the diameter of the acorn, the acorn is subjected to radial extrusion. The protrusions 63 act as local stress points, concentrating the extrusion force on the weak points of the shell, promoting crack propagation, and achieving shell rupture.
[0026] Reference Figure 1-5 The screening mechanism 7 includes rocker arms 71. Four rocker arms 71 are rotatably connected to the inner side of the support frame 1 via hinge shafts. All four rocker arms 71 are fixedly connected to the screening seat 72. Several screening shafts 73 are rotatably connected to the inner side of the screening seat 72. The screening seat 72 is inclined with the left side lower and the right side higher. A hinge seat 74 is fixedly connected to the right end of the screening seat 72. A rocking arm 75 is hinged to the inner side of the hinge seat 74 via a hinge shaft. Two rotating seats 76 are fixedly connected to the right end of the support frame 1. The inner sides of the two rotating seats 76 are rotatably connected to the transmission shaft 77. A cam 78 is fixedly connected to the outer side of the transmission shaft 77. The rocking arm 75 is hinged to the cam 78.
[0027] With the above structural configuration, the drive mechanism 8 drives the cam 78 to rotate via the transmission shaft 77. The eccentric profile of the cam 78 pushes the rocker arm 75, which is hinged to it, to perform periodic reciprocating oscillations. The rocker arm 75 is rigidly connected to the screening seat 72 via the hinge seat 74, thereby transmitting the oscillation to the entire screening seat 72. The screening seat 72 is supported on the support frame 1 by four sets of rocker arms 71 via hinge shafts, forming a stable inclined plane (left lower, right higher). This design allows the screening seat 72 to produce a planar oscillating motion in the back-and-forth direction under the drive of the cam 78. The shelled mixture (kernels, broken shells, coatings) falls onto the surface of the inclined screening seat 72. The screening shaft 73 (which can also be replaced by a screen) on the inner side of the screening seat 72 moves synchronously with the screening seat 72, and the planar oscillation causes the material to tumble in a directional jumping motion. The gaps between the multiple parallel screening shafts 73 allow the broken shells and coatings to fall into the screening seat 72, while the kernels roll on the surface of the screening shafts 73. The periodic oscillation and rotation of the screening shafts 73 can prevent the broken shells from clogging the screen holes. Light broken shells and coatings are collected through the broken material channel (not shown in the figure) due to the tilt (left lower and right higher) and reciprocating oscillation. The pure kernels are output through the whole material channel (not shown in the figure).
[0028] Reference Figure 1-5 The drive mechanism 8 includes a drive motor 81, which is fixedly connected to the support frame 1. A first belt pulley transmission mechanism 82 is provided on the outside of the drive motor 81. The first belt pulley transmission mechanism 82 is located on the outside of the right peeling shaft 61. The two peeling shafts 61 are connected by a second belt pulley transmission mechanism 83. The right peeling shaft 61 is connected to the transmission shaft 77 by a third belt pulley transmission mechanism 84.
[0029] With the above structural configuration, after the drive motor 81 starts, it transmits power to the right peeling shaft 61 through the first belt pulley transmission mechanism 82. The output shaft of the drive motor 81 is connected to the small pulley (driving pulley) of the first belt pulley transmission mechanism 82 through a flat belt or a V-belt. The large pulley (driven pulley) of the first belt pulley transmission mechanism 82 is fixed to the end of the right peeling shaft 61. The rotational power is transmitted to the shaft through the friction generated by the belt tension, driving the peeling roller 62 and the protrusion 63 on its outer side to rotate. The rotation of the right peeling shaft 61 is linked to the left peeling shaft 61 through the second belt pulley transmission mechanism 83, realizing dual-shaft coordination. The pulley of the right peeling shaft 61 drives the belt of the left peeling shaft 61 through the belt. The two shafts rotate at the same speed but in opposite directions (i.e., the driving and driven wheels of the second belt pulley transmission mechanism 83 have the same diameter); the reverse rotation of the two shafts causes the protrusions 63 of the shelling roller 62 to form a "shearing and rubbing zone", where the acorns are squeezed and the shells are torn in the gap between the rollers, while avoiding excessive breakage of the kernels due to unidirectional force; the power of the right shelling shaft 61 is transmitted to the transmission shaft 77 of the screening mechanism 7 through the third belt pulley transmission mechanism 84; a third-stage pulley is added to the end of the right shelling shaft 61, which is connected to the pulley at the end of the transmission shaft 77 through a flat belt, diverting part of the power to the screening mechanism 7; the transmission shaft 77 drives the cam 78 on its outer side to rotate, and the profile of the cam 78 pushes the rocking arm 75 to swing periodically. The swing arm 75 drives the screening seat 72 through the hinge seat 74, and forms a back-and-forth planar swing motion under the support of four sets of rocker arms 71, realizing the tumbling and stratification of materials on the screening shaft 73. It should be noted that the first belt pulley transmission mechanism 82, the second belt pulley transmission mechanism 83 and the third belt pulley transmission mechanism 84 can also be replaced by mechanisms such as chain and sprocket transmission mechanisms that can achieve the transmission effect.
