Description

Technical Field

[0001] This utility model relates to a food auxiliary processing equipment, specifically a fully automatic sunflower seed shelling machine. Background Technology

[0002] A sunflower seed shelling machine is a mechanical device that uses a power mechanism to crack the outer shell of sunflower seeds, thereby separating the kernel from the shell. Because it can partially replace the manual labor of using one's teeth, it has the effect of protecting teeth and is safer and more hygienic.

[0003] Existing sunflower seed shelling machines typically consist of a power unit, a crushing mechanism, and a material discharge device. Their structure and function are relatively simple, requiring users to feed the seeds one by one into the crushing mechanism. Furthermore, the crushing mechanism has poor compatibility with different seed sizes, making fully automated shelling impossible. While existing automated shelling equipment, such as the Chinese invention patent with publication number CN107927809A, discloses a collision-type sunflower seed shelling robot, which uses a crushing blade to break the shell and a catapult collision device to separate the seeds, achieving fully automated shelling, it requires two motors and an external air source, resulting in a complex structure and high production costs. Summary of the Invention

[0004] This utility model provides a fully automatic sunflower seed shelling machine, which is small in size and low in cost. It can realize fully automatic feeding, shelling and unloading, and has a high success rate in shelling sunflower seeds, freeing up the user's hands.

[0005] The technical solution adopted by this utility model is: a fully automatic sunflower seed shelling machine, including a machine shell, a power mechanism, a feeding mechanism, a shell breaking mechanism, and a unloading mechanism.

[0006] The power mechanism includes a motor, which is positioned perpendicular to the bottom surface of the lower housing along its output shaft axis and is fixed to the bottom surface of the lower housing via a connector. The power mechanism also includes a turntable, which is mounted on the output shaft of the motor. The turntable does not rotate relative to the motor output shaft, and the axis of the motor output shaft coincides with the axis of rotation of the turntable. One side of the turntable has an end face cam, and the other side has a radial cam. The end face of the end face cam slides in contact with the bottom surface of the pusher plate, and the radial cam slides in contact with the shell-breaking rod.

[0007] In one embodiment, the motor drives the turntable to rotate, and the turntable drives the pusher plate to reciprocate in a direction perpendicular to the turntable surface via the end face cam.

[0008] In another embodiment, the motor drives the turntable to rotate, and the turntable pushes the shell-breaking rod to reciprocate in the horizontal direction through the radial cam.

[0009] The feeding mechanism includes a hopper, which is formed on the top surface of the upper shell and is funnel-shaped to hold sunflower seeds. One side of the hopper extends into a material selection trough. There are stepped fixed plates between the two side walls of the material selection trough. The push plate is formed with stepped sliding plates, which are interlocked and slidably engaged with the fixed plates.

[0010] In one embodiment, as the turntable rotates, the pusher plate, constrained by the material selection slot, the fixed plate, and the turntable end face cam, can reciprocate up and down relative to the turntable surface.

[0011] In another embodiment, the sunflower seeds in the hopper are selected and pushed upwards one by one along the stepped direction by the alternating pusher plate and the fixing plate until they reach the top of the selection trough. The feeding mechanism also includes a slide, one end of which is connected to the outer side of the selection trough, and the other end is connected to the material trough. The slide is inclined and the end of the slide connected to the selection trough is at a higher position. The material trough has a structure with openings at the top and bottom and closed sides. The upper opening surface of the material trough is formed on the upper shell and continues with the slide. The lower opening surface of the material trough slides in parallel contact with the upper surface of the turntable. A material window is formed on the turntable, and the size of the material window is greater than or equal to the opening area of ​​the material trough.

[0012] In one embodiment, the sunflower seeds that slide down from the top of the selection trough slide into the material trough along the slide.

[0013] In another embodiment, the sunflower seeds that have slid into the feed trough cannot continue to fall downwards due to the obstruction of the turntable. As the turntable rotates, when the feed window on the turntable rotates to the bottom of the feed trough, the sunflower seeds pass through the feed window and continue to fall downwards into the shell-breaking trough.

[0014] The shell-breaking mechanism includes a shell-breaking rod, which is a linear reciprocating push rod with a central ring shape. One end face of the shell-breaking rod has a groove. Under the constraint of a limiting boss and a limiting plate, the shell-breaking rod can reciprocate along the long axis of the shell-breaking groove. The limiting boss is formed on the base, and the limiting plate is fixed to the limiting boss by screws. One end of the shell-breaking rod slides close to the bottom and side surfaces of the shell-breaking groove. The shell-breaking mechanism also includes a shell-breaking groove, which consists of a bottom surface and three side walls. The bottom surface and two side walls are formed on the base, and one side wall is formed by the end face of the shell-breaking rod. A through hole is opened on one side wall of the shell-breaking groove. The upper opening of the shell-breaking groove is aligned with the material trough, and the size of the shell-breaking groove is slightly larger than the material window.

[0015] In one embodiment, a radial cam drives a shell-breaking rod to squeeze the sunflower seeds axially, causing the seed shells to break.

[0016] The unloading mechanism includes an unloading hole formed on the base, one side of which is adjacent to the shell-breaking groove. The unloading mechanism also includes an unloading plate formed on the same side of the turntable as the radial cam. The unloading plate is perpendicular to the turntable surface and is arc-shaped with the center of the arc located on the axis of rotation of the turntable. One side of the unloading plate is in sliding contact with the bottom surface of the shell-breaking groove.

[0017] In one embodiment, as the turntable rotates, the unloading plate can pass through the through hole on one side wall of the shell-breaking trough and push the sunflower seed material in the shell-breaking trough into the unloading hole.

[0018] The implementation of this utility model has at least the following advantages: 1. The sunflower seed shelling machine of this utility model is fully automatic and can separate and shell the sunflower seeds in the hopper one by one, freeing the user's hands and providing convenience. 2. The sunflower seed shelling machine of this utility model is driven by only one motor. This motor can drive the feeding mechanism, the shell-breaking mechanism and the unloading mechanism at the same time, which helps to simplify the structure of the sunflower seed shelling machine, reduce the size and weight of the sunflower seed shelling machine and reduce production costs. 3. The sunflower seed shelling machine of this utility model has less limitation on the width of sunflower seeds, is suitable for sunflower seeds of various sizes, and has a high success rate in shelling.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings and examples. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Combination Figures 1 to 8 As shown, this utility model discloses a fully automatic sunflower seed shelling machine, which includes a shell, a power mechanism, a feeding mechanism, a shell-breaking mechanism, and a unloading mechanism.

[0022] Combination Figure 2 , Figure 3 , Figure 4 As shown, the power mechanism includes a motor 7, a turntable 3, an end face cam 302, and a radial cam 301. Preferably, the motor 7 is a geared motor with an output shaft speed of 10-50 revolutions per minute. The output shaft axis of the motor 7, the rotation axis of the radial cam 301, and the rotation axis of the end face cam 302 coincide with the rotation axis of the turntable 3. One side of the turntable 3 is formed with an end face cam 302, and the other side is formed with a radial cam 301. The end face of the end face cam 302 is an inclined surface. The inclined surface of the end face cam 302 slides in contact with the bottom surface of the pusher plate 2. Under the constraint of the fixed plate 102, the material selection groove 105, and the end face cam 302, the pusher plate 2 performs up-and-down reciprocating motion.

[0023] Combination Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, the inside of the shell-breaking rod 5 is a smooth hollow structure. The radial cam 301 is located inside the shell-breaking rod 5. The outer wall of the radial cam 301 slides in contact with the inner wall of the shell-breaking rod 5. The output shaft of the motor 7 is fixedly connected to the turntable 3, and the two do not rotate relative to each other.

[0024] Combination Figure 2 , Figure 3 , Figure 7As shown, the motor 7 drives the turntable 3 to rotate. The turntable 3 pushes the pusher plate 2 to reciprocate along a direction perpendicular to the turntable 3 via the end face cam 302. Under the push of the sliding plate 201, the sunflower seeds in the hopper 101 are pushed one by one to the top of the selection trough 105 and slide down into the slide 103 from one side of the fixed plate 102. Finally, the sunflower seeds slide down into the trough 104 along the slide 103. The sunflower seeds that slide into the trough 104 cannot continue to fall down due to the obstruction of the turntable 3. As the turntable 3 rotates, when the material window 304 on the turntable 3 rotates to the bottom of the trough 104, the sunflower seeds pass through the material window 304 and continue to fall down into the shell-breaking trough 401, thus completing the feeding process.

[0025] Combination Figure 5 , Figure 7 As shown, the motor 7 drives the turntable 3 to rotate, and the turntable 3 pushes the shell-breaking rod 5 to reciprocate in the horizontal direction through the radial cam 301. The end face of the shell-breaking rod 5 pushes the sunflower seed material to squeeze one side of the shell-breaking groove 401, thus breaking the shell.

[0026] Combination Figure 7 , Figure 8 As shown, the shell-breaking groove 401 consists of a bottom surface and three side walls. The bottom surface and two side walls are formed on the lower shell 4, and one side wall is formed by the end face of the shell-breaking rod 5. A through hole 404 is provided on one side wall of the shell-breaking groove 401. The unloading plate 303 rotates around the center of the turntable 3 under the drive of the turntable 3, and the unloading plate 303 can pass through the through hole 404 and push the sunflower seed material in the shell-breaking groove 401 into the unloading hole 403 to complete the unloading process.
