Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of shelling tools for Acer truncatum seeds, and in particular to a shelling device for Acer truncatum seeds. Background Technology
[0002] In the deep processing industry of Acer truncatum seeds, shell-kernel separation is a key pre-processing step for subsequent oil extraction and food processing. However, Acer truncatum seeds have the characteristics of "hard and tough outer shell and fragile and easily broken kernel". Traditional shelling technology has long been limited by the problems of "incomplete shelling" and "insufficient raw material turning", resulting in low processing efficiency, serious waste of raw materials, and difficulty in meeting the needs of large-scale production. Traditional Acer truncatum seed shelling equipment mostly uses a "static crushing" shelling method. Its core structure consists of two crushing plates with a fixed distance between them. The Acer truncatum seeds are squeezed by the gravity or hydraulic pressure of the upper plate. The seeds only bear the pressure in the vertical direction. The outer shell must be completely in contact with the plate to break. However, gaps between the seeds or irregularly shaped seeds can easily cause some of the outer shell to crack but not fall off. In some cases, uneven force can cause the kernel to break first while the outer shell remains intact. Therefore, these problems need to be solved. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Example: See Figures 1 to 4 This utility model discloses a shelling device for Acer truncatum seeds, comprising a machine body 8, a base plate fixedly connected to the bottom of the machine body 8, a mounting base welded to one side of the base plate, and a first motor 2 mounted on the mounting base. The first motor 2 provides rotational power to the rotating shaft, driving the shelling component to swing back and forth, thereby achieving all-round shelling of Acer truncatum seeds. A feeding hopper 1 is fixedly connected to the top of the machine body 8, which guides the raw materials to concentrate into the shelling area inside the machine body 8, preventing the raw materials from scattering. A dust collection box 4 is fixedly connected to one side of the machine body 8, and a discharge pipe is provided on one side of the bottom of the dust collection box 4. A rotating shaft is rotatably mounted on the inner wall of the machine body 8, and a shelling component is fixedly connected to the rotating shaft. A discharge door 7 is movably provided at the bottom of the machine body 8, which allows the shelled material to enter the discharge chamber 11. At the same time, it automatically closes under the action of a return spring, realizing intermittent material discharge.
[0015] In this utility model, a material discharge chamber 11 is provided on one side of the bottom of the machine body 8. A discharge gate 7 is rotatably provided on the top of the material discharge chamber 11. A return spring is installed on the discharge gate 7. One end of the discharge pipe extends to the bottom of the material discharge chamber 11. A support bearing seat is fixedly connected inside the discharge pipe. A second spiral blade 10 for pushing the material out is rotatably provided at the bottom of the material discharge chamber 11. The other end of the second spiral blade 10 is rotatably connected to the support bearing seat. A third motor is installed on the other side of the machine body 8. The output end of the third motor is coaxially fixedly connected to the second spiral blade 10. The second spiral blade 10 facilitates continuous and stable material conveying to the discharge pipe, thereby pushing it to the outside of the machine body 8, realizing automatic material conveying. The shelling component includes two support plates symmetrically fixedly connected to the rotating shaft. A mounting plate 9 is welded to the bottom of the two support plates. A first spiral blade 5 is rotatably provided between the two mounting plates 9. A second motor 12 is installed on one side of one mounting plate 9. The output end of the second motor 12 is coaxially fixedly connected to the first spiral blade 5. The shell component facilitates the squeezing, friction, and pushing of the Acer truncatum seeds, achieving separation of the shell from the kernel. A rotating bearing is installed at the connection position between the mounting plate 9 and the first spiral blade 5. Four connecting beams 6 are axially arrayed between the two mounting plates 9, and the four connecting beams 6 are distributed around the first spiral blade 5. A protrusion for pushing the discharge gate 7 is fixed to one side of each of the two mounting plates 9. The mounting plates 9 facilitate the rotation of the entire shelling component with the rotating shaft. A first pulley is fixed to the output end of the first motor 2, and a second pulley is fixed to one end of the rotating shaft extending out of the outer wall of the machine body 8. A transmission belt 3 for transmission is sleeved between the first pulley and the second pulley, which facilitates the transmission of the motor's rotational motion to the shelling component. An induced draft fan is installed on the top of the dust collection box 4. Three inclined air guide pipes connect the dust collection box 4 and the machine body 8. Three filter plates are equidistantly arranged inside the dust collection box 4, which facilitates the collection of dust and debris generated during the shelling process, avoiding dust pollution of the environment.
[0016] Working Principle: When using this utility model, firstly, connect each electrical component in this application to the power supply. Then, start the device. The first motor 2 is fixed to the base plate via the mounting base. The first pulley at its output end drives the second pulley at the end of the rotating shaft to rotate via the transmission belt 3. The rotating shaft performs alternating forward and reverse reciprocating motion under the support of the side wall of the machine body 8. At the same time, the second motor 12, mounted on one side mounting plate 9, swings synchronously with the shelling component. Its output end drives the first spiral blade 5 between the two mounting plates 9 to rotate at high speed. This composite motion of "semi-circular reciprocating oscillation + spiral rotation" provides multi-directional squeezing, friction, and impact forces for shelling Acer truncatum seeds. Then, operate... Personnel feed Acer truncatum seeds into the feed hopper 1 at the top of the machine body 8. The funnel-shaped feed hopper 1 guides the raw material through its inclined inner wall, concentrating it into the shelling area inside the machine body 8. This area is enclosed by two mounting plates 9, four axially arrayed connecting beams 6, and a first spiral blade 5. These blades reciprocate in a semi-circular motion synchronously with the shelling component. During shelling, the high-speed rotating first spiral blade 5 generates an axial pushing force on the raw material through its spiral structure. Simultaneously, the reciprocating oscillation of the shelling component causes the space between the connecting beams 6 and the first spiral blade 5 to change periodically: when the shelling component oscillates to one side, the raw material is squeezed between the connecting beams 6 and the spiral blades, and the outer shell cracks due to friction and compression; when oscillating in the opposite direction, the raw material... The material tumbles under inertia, with the unshelled portion turning towards the force-bearing surface. Combined with the continuous rotation of the spiral blades, the outer shell and kernel are gradually separated. Simultaneously, dust and fine shell fragments generated during the shelling process are drawn into the dust collection box 4 by a fan at the top of the dust collection box 4 through three inclined air ducts between the machine body 8 and the dust collection box 4. The inclined design of the air ducts utilizes gravity to assist dust settling, preventing suspended dust from flowing back to the shelling area. Then, the shelled material is pushed towards the bottom of the machine body 8 by the reciprocating motion of the shelling component. When the shelling component swings to the side near the discharge chamber 11, the protrusion on the mounting plate 9 presses against the discharge gate 7, overcoming the spring force of the return spring and pushing it open. The material then passes through the top opening of the discharge chamber 11. The material enters the discharge chamber 11 through the inlet; when the shelling component swings in the opposite direction and the protrusion leaves, the discharge gate 7 automatically closes under the action of the return spring, realizing intermittent discharge and ensuring that the amount of material falling into the discharge chamber 11 each time is uniform. Finally, the material falling into the discharge chamber 11 accumulates to the bottom under the action of gravity. At this time, the third motor drives the second spiral blade 10 in the discharge chamber 11 to rotate, and the material is transported to the outside of the machine body 8 through the spiral pushing force, completing the collection of the shelled material. The fit gap between the second spiral blade 10 and the inner wall of the discharge chamber 11 is small, which can avoid material residue, and the conveying speed matches the intermittent discharge rhythm to prevent the discharge chamber 11 from being blocked. At this point, the use of the Acer truncatum seed shelling device ends.
