Description

Technical Field

[0001] The invention relates to food processing equipment, in particular to a melon seed shelling device. Background Art

[0002] Melon seeds are a common food that people love to eat. People usually eat the seeds by cracking the shells one by one with their teeth. However, cracking the seeds for a long time will cause uneven teeth and blistering on the tip of the tongue. If you use a melon seed clamp to peel the seeds, although the problem of teeth and tongue tip is solved, you still have to peel the seeds one by one, which is very inefficient. For a melon seed food processing factory, it is unhygienic if workers use their teeth to peel the seeds, and it is inefficient if workers use a melon seed clamp to peel the seeds.

[0003] In order to solve the above problems, we invented a melon seed peeling device suitable for batch processing and production. Summary of the invention

[0004] The invention aims to solve the problem that peeling melon seeds with teeth is unhygienic and easy to damage teeth, and peeling melon seeds with a melon seed clamp is inefficient. The specific solution is as follows:

[0005] A melon seed shelling device includes a melon seed supply box, an adapter box, an output pipe, a shelling machine, a shelling machine, a bending pipe, a shell collecting barrel, a kernel collecting barrel, an electrical control box, and a clamping block. The melon seed supply box is a flat hollow body with a larger upper part and a smaller lower part and a box cover. The height of its internal space is greater than the thickness of a piece of melon seeds and less than the thickness of two pieces of melon seeds. A square hole is provided at the lower end of the melon seed supply box to allow a piece of melon seeds to fall freely. The internal space of the melon seed supply box within the square hole gradually expands upward. The square hole protrudes from the lower end of the melon seed supply box and is inserted into the upper end of the output pipe. The adapter box sleeves the lower part of the melon seed supply box with the upper part of the output pipe. The shelling machine is composed of a left shelling arm, a right shelling arm, a left shelling rod, a right shelling rod, a connecting strip, a rotating wheel, a sliding shaft, a shelling motor, a shell, and a cushion block. The concave ends of the left and right shell-pressing arms are arranged opposite to each other and are respectively aligned with the outwardly facing square openings arranged on the left and right sides of the lower end of the output tube matched therewith. The other ends of the left and right shell-pressing arms are respectively vertically fixedly connected to one end of the left and right shell-pressing rods. The other ends of the left and right shell-pressing rods are provided with round through holes, which are respectively sleeved on the two ends of the sliding shaft fixed in the cushion block. The lower part of the cushion block is fixedly connected to the inner side of the bottom of the shell. The shell-pressing motor is fixed on the cushion block. The shaft of the shell-pressing motor is fixedly connected to the rotating wheel. Two pillars are symmetrically arranged on the diameters on both sides of the center of the rotating wheel. One end of the two connecting strips is hooked in the round hole of one of the pillars, and the other end is hooked in the middle round hole of the left and right shell-pressing rods. The shell is fixed on the wall.

[0006] The shell splitting machine located at the lower end port of the output pipe is composed of a front shell splitting sheet, a rear shell splitting sheet, a shell splitting cavity, a front shell splitting motor, and a rear shell splitting motor. The interior of the shell splitting cavity is a channel for the melon seed kernels to slide down from top to bottom. The left and right ends of the front lower part of the shell splitting cavity are provided with circular rings for allowing the rotating shaft of the front shell splitting motor to penetrate from left to right. The straight lower end of the front shell splitting sheet is fixedly connected to the rotating shaft of the front shell splitting motor passing between the circular rings. The front shell splitting sheet leans upward against the front of the shell splitting cavity, and its upper end is provided with a slope that bends backward and gradually becomes thinner. The left and right ends of the rear lower part of the shell splitting cavity are provided with circular rings for allowing the rotating shaft of the rear shell splitting motor to penetrate from right to left. The straight lower end of the rear shell splitting sheet is fixedly connected to the rotating shaft of the rear shell splitting motor passing between the circular rings. The rear shell splitting sheet leans upward against the back of the shell splitting cavity, and its upper end is provided with a slope that bends forward and gradually becomes thinner, and closes with the upper end of the front shell splitting sheet. The left and right sides of the shelling cavity are exposed outside the front shelling sheet and the rear shelling sheet, and are respectively fixedly connected to one end of a bracket fixed to the wall. The front shelling motor and the rear shelling motor are respectively fixedly connected to one end of a support bar fixed to the wall. One end of the bent pipe is fixed to the lower end of the shelling cavity, and the other end faces the mouth of the kernel collecting barrel, and the shell collecting barrel is located below the shelling machine. One end of the clamping block is fixed to the wall, and the other end is clamped on the left and right sides of the middle of the melon seed supply box. The electrical control box is electrically connected to the shell pressing motor, the front shelling motor and the rear shelling motor respectively.

[0007] The output tube is rectangular, and its internal space only allows one melon seed after another to pass through. The shell pressing motor, the front shell splitting motor and the rear shell splitting motor are stepping motors. The outer shell is provided with slots for the left shell pressing rod and the right shell pressing rod to slide. The back of the adapter box is fixedly connected to one end of a fixed block fixed to the wall. A handle is provided in the middle of the box cover. The concave ends of the left shell pressing arm and the right shell pressing arm match the shapes of the two sides of the melon seeds. The left shell pressing arm and the right shell pressing arm have the same structure, are located on the same straight line, and are parallel to the sliding shaft. The front shell splitting motor is located on the left side of the shell splitting machine, and the rear shell splitting motor is located on the right side of the shell splitting machine. The shell splitting cavity is strip-shaped, and its length matches the length of the straight section of the front shell splitting sheet. The front shell splitting sheet has the same structure as the rear shell splitting sheet.

[0008] The working process of this device is described as follows:

[0009] First, open the cover of the melon seed supply box, put in an appropriate amount of melon seeds, shake the melon seed supply box horizontally so that all the melon seeds inside are flat on the bottom of the box without stacking, then close the cover, put the melon seed supply box with the big end upward and the small end downward, and vertically insert it into the clamp and the adapter box. At this time, the melon seeds in the melon seed supply box will fall into the output pipe one by one from the square hole at the lower end of the melon seed supply box under the action of gravity. The melon seeds at the bottom of the output pipe are blocked by the front shelling piece and the rear shelling piece on the shelling machine. Turn on the power switch of the electrical control box, and the electrical control box The shelling machine is automatically controlled to shell the melon seeds between the concave ends of the left shelling arm and the right shelling arm, and then the front shelling motor and the rear shelling motor of the shelling machine are controlled to perform shelling operations at the same time. The front shelling piece is inserted into the front shell of the melon seeds and separates the front shell and drops it into the shell collecting barrel below, and the rear shelling piece is inserted into the rear shell of the melon seeds and separates the rear shell and drops it into the shell collecting barrel below. The shelled melon seed kernels fall into the shelling cavity and fall into the kernel collecting barrel along the curved pipe. After one piece of melon seeds is shelled, the next piece of melon seeds is automatically shelled according to the same steps as before.

[0010] In summary, the technical solution of the present invention has the following beneficial effects:

[0011] The invention solves the problems of unhygienic and bad teeth-peeling melon seeds with teeth and low efficiency of peeling melon seeds with melon seed clamps. At the same time, only one worker needs to load melon seeds in batches and press the power switch of the electrical control box to take out melon seed kernels and melon seed shells in batches. The device will automatically perform the melon seed shelling operation, saving labor, improving production efficiency, ensuring the hygiene of melon seed processing, and being suitable for mass production needs.
