Description

A lifting bin type bitter melon seed and skin separator

Technical Field

The invention relates to the field of agricultural machinery, in particular to a lifting bin type bitter melon seed and skin separator.

Background technique

Bitter melon, also known as bitter gourd, is a plant of the genus Momordica in the Cucurbitaceae family. It is an annual climbing herb native to the tropical regions of East India and is also widely cultivated in both the north and south of my country. Bitter melon has a sweet and bitter taste and is a nutritious vegetable. It can also be used as a traditional Chinese medicine, with the effects of dispelling summer heat, clearing away heat, improving eyesight and detoxifying. The fruit of bitter melon is spindle-shaped or cylindrical, with many warts on the outer surface, about 100-200mm long, orange-yellow when mature, and split from the top. When bitter melon matures, the surface of its seeds is covered with a layer of red coating, which is the bitter melon seed coat. Most bitter melon seeds are oblong, with serrations at both ends and engraved on both sides. The seeds are about 10-20mm long, 5-10mm wide, and 2-4mm thick.

In the process of hybrid seed production and material purification and rejuvenation of bitter melon, it is necessary to remove the bitter melon seed coat, then dry it and store it for later use. The existing methods for separating the bitter melon seed coat include manual and mechanical methods. Among them, the manual method is to put the bitter melon seeds in a sieve basket or a mesh bag and rub and wash them repeatedly by hand, which is labor-intensive, time-consuming, low in efficiency, wastes water resources, and has poor cleaning effect.

The mechanical separation method also has the problem of difficulty in separating and cleaning the seed coat:

Chinese utility model patent CN 219441849U "A bitter melon seed collection device" discloses a bitter melon seed collection device. The device pours bitter melon into the inner side of the feed box through the feed hopper, and the bitter melon is crushed under the action of two crushing rollers, and then moves to the right side under the action of the spiral blade to enter the inner side of the outer box, and the elliptical block rotates, and the porous plate and the filter plate are reciprocated up and down under the action of eight corresponding springs. The crushed bitter melon entering the inner side of the outer box is filtered by the porous plate and the filter plate in turn, and the pulp moves to the left side to enter the inner side of the connecting box for collection. After passing through the filter plate, the bitter melon seeds move to the bottom of the outer box for collection. This device has a complex structure and has no cleaning function. After the bitter melon pulp and seed coat are crushed under the action of the two crushing rollers, they form a solid-liquid mixture with the seeds with a high viscosity. When passing through the porous plate and the filter plate, the holes are easily blocked, and clean seeds cannot be separated. Manual secondary separation and cleaning are required, which is time-consuming and labor-intensive.

Chinese utility model patent CN 205052096U "Bitter melon seed coat stripper" discloses a bitter melon seed coat stripper, including a container, a net bag and a squeeze plate. During operation, the seeds are placed in the net bag, and then the net bag is placed in the container, the net bag is continuously squeezed with the squeeze plate, and then the mixture of seeds and seed coats is rinsed with water. This device has a simple structure and no cleaning function. It takes a long time to squeeze the net bag with the squeeze plate to separate the seeds from the seed coat, and both separation and cleaning require manual operation, which is time-consuming and laborious.

Detailed ways

The present invention is further described in detail below in conjunction with the accompanying drawings.

The invention provides a lifting bin type bitter melon seed and skin separator which is mainly composed of a driving pipe, a cleaning barrel, a metal spiral rod, a driving head, a fixed head, a separation bin, upper and lower threaded rods, upper and lower threaded mounting plates, a spring and the like.

The driving tube Ⅰ4, the driving tube Ⅱ5 and the supporting sleeve 13 are all hollow steel tubes. The handle glove 2 is sleeved on the upper end of the driving tube Ⅰ4, and the two are clearance-matched. The upper end of the handle glove 2 is an upper end cover 1 fixedly mounted on the upper end of the driving tube Ⅰ4, and below it is a lower retaining ring 3 fixedly mounted on the driving tube Ⅰ4. The distance between the lower end surface of the upper end cover 1 and the upper end surface of the lower retaining ring 3 is slightly greater than the length of the handle glove 2. When the handle glove 2 is held by hand and pressed down and lifted vertically, the upper end surface of the lower retaining ring 3 limits its downward freedom relative to the driving tube Ⅰ4, and the lower end surface of the upper end cover 1 is limited to its upward freedom relative to the driving tube Ⅰ4, and the driving tube Ⅰ4 can rotate freely inside the handle glove 2.

The lower end of the drive tube I4 passes through the upper and lower end openings of the drive tube II5 and extends into the support sleeve 13 through the upper end opening of the support sleeve 13. A drive head 11 is fixed inside the lower end of the drive tube I4, and the lower end surface of the drive head 11 is flush with the lower end surface of the drive tube I4.

A fixed head 20 is fixedly installed in the lower end of the support sleeve 13, and the lower end surface of the fixed head 20 is flush with the lower end surface of the support sleeve 13. The lower end of the support sleeve 13 is fixedly connected to the barrel shaft 21. The lower end of the barrel shaft 21 passes through the central axis hole at the bottom of the cleaning barrel 9 and is fixedly connected thereto.

The pipe opening at the upper end of the driving tube II5 is fixedly connected to the outer wall of the driving tube I4. The inner diameter of the driving tube II5 is larger than the outer diameter of the driving tube I4. The gap between the inner wall of the driving tube II5 and the outer wall of the driving tube I4 is slightly larger than the wall thickness of the supporting sleeve 13.

When the driving tube I4 and the driving tube II5 rotate together and move up and down, they move relative to the supporting sleeve 13 fixedly installed between the two.

The lower end of the driving tube II 5 passes through the central axis hole of the mounting plate 6 on the threaded rod and is fixedly connected thereto, and the end surface of the lower end of the driving tube II 5 is flush with the lower end surface of the mounting plate 6 on the threaded rod.

The metal spiral rod 12 is divided into a straight rod portion 24 and a spiral portion 25. The straight rod portion 24 is inserted into the center hole of the fixed head 20, and the two are fixedly connected. A track that can engage with the spiral portion 25 is provided in the center of the drive head 11, and the drive head 11 is always engaged with the spiral portion 25. When the hand holds the handle sleeve 2 and presses down or lifts up vertically, the drive tube I4 gives the drive head 11 a downward or upward force, and the drive head 11 can rotate along the spiral portion 25 and move downward or upward at the same time. The drive head 11 drives the drive tube I4 to rotate synchronously and move up and down. The drive tube I4 and the drive tube II5 are fixedly installed to rotate and move up and down together, and the drive tube II5 drives the mounting plate 6 on the threaded rod to rotate and move up and down together.

The threaded rod upper mounting plate 6 is provided with a plurality of upper threaded rod mounting holes 27, and a plurality of ball positioning holes 26 are provided on the circumferential edge of the lower end surface thereof, and balls are installed in the ball positioning holes 26. The bottom surface and the side wall of the separation bin 14 are provided with a plurality of sieve holes 31, and the size of the sieve holes 31 is preferably such that the bitter melon seeds can be prevented from passing through. The width of the long hole sieve is smaller than the thickness of the bitter melon seeds, and the diameter of the round hole sieve is smaller than the width of the bitter melon seeds. The present invention takes the long hole sieve as an example.

The diameter of the bottom hole 29 of the separation bin is larger than the diameter of the lower threaded rod 15. There is a gap between the inner wall of the bottom hole 29 of the separation bin and the outer wall of the lower threaded rod 15. The gap has the same function as the sieve hole 31, which can prevent bitter melon seeds from passing through, but allows water, broken seed coats and shriveled seeds to pass through; the diameter of the central bottom hole of the separation bin 14 is slightly larger than the outer diameter of the support sleeve 13 and smaller than the outer diameter of the small spring 22.

The outer diameter of the upper end surface of the side wall of the separation chamber 14 is equivalent to the outer diameter of the threaded rod upper mounting plate 6, and a ball track 28 is provided thereon. When the lower end surface of the threaded rod upper mounting plate 6 contacts and rotates relatively with the upper end surface of the side wall of the separation chamber 14, the balls in the ball positioning holes 26 roll in the ball track 28 to reduce friction resistance. A plurality of guide plates I30 are provided on the outer side wall of the separation chamber 14 to limit its circumferential freedom, but it can move up and down in the limiting slide 19.

The threaded rod lower mounting plate 16 is provided with a plurality of threaded rod mounting holes 33, and the outer side wall is provided with a plurality of guide plates II 32, which are used to limit its circumferential freedom, but can move up and down in the limit slide 19. The separation bin bottom hole 29 and the threaded rod lower mounting hole 33 correspond one to one, and the setting principle of the threaded rod upper mounting hole 27 and the threaded rod lower mounting hole 33 is: the upper threaded rod 7 and the lower threaded rod 15 do not interfere when they rotate relative to each other, and the minimum radial spacing between the two can at least pass a bitter melon seed horizontally. When both the upper threaded rod 7 and the lower threaded rod 15 are completely entered into the separation bin 14 (as shown in the following working step (III), Figure 11), the distance between the lower end face of the upper threaded rod 7 and the upper end face of the separation bin 14 is greater than the size of a bitter melon seed, and the distance between the upper end face of the lower threaded rod 15 and the lower end face of the threaded rod upper mounting plate 6 is greater than the size of a bitter melon seed.

The spring sleeve 23 is divided into an inner tube 34 and an outer tube 35. The inner diameter of the inner tube 34 is slightly larger than the outer diameter of the support sleeve 13. The upper end of the spring sleeve 23 passes through the central axis hole of the threaded rod lower mounting plate 16 and is fixedly connected thereto, and the end face of the upper end of the spring sleeve 23 is flush with the upper end face of the threaded rod lower mounting plate 16. The small spring 22 is placed in the gap between the inner tube 34 and the outer tube 35, and the lower end of the small spring 22 is fixedly mounted on the bottom plate between the inner tube 34 and the outer tube 35, and the small spring 22 moves up and down synchronously with the threaded rod lower mounting plate 16. The inner diameter of the large spring 18 is larger than the outer diameter of the outer tube 35 of the spring sleeve 23, and its upper end is fixedly mounted on the lower end face of the threaded rod lower mounting plate 16, and its lower end is fixedly mounted on the upper end face of the bottom of the cleaning bucket 9.

When the separation chamber 14 moves downward under the pressure of the threaded rod mounting plate 6 (such as the position in the following working step (ii), Figure 10), its bottom lower end surface begins to compress the small spring 22. When the bottom lower end surface of the separation chamber 14 contacts the upper end surface of the threaded rod lower mounting plate 16, the lower threaded rod 15 now completely enters the separation chamber 14, and the small spring 22 is now completely compressed into the gap between the inner tube 34 and the outer tube 35. If the separation chamber 14 continues to move downward, the small spring 22 can no longer be compressed. The large spring 18 is compressed by a small distance by the threaded lower mounting plate 16 under the reaction force of the small spring 22. At this time, the threaded rod lower mounting plate 16 moves downward by the distance that the large spring is compressed. The separation chamber 14 continues to move downward to the lowest position (such as the following working step (iv), Figure 12), and the large spring 18 is compressed to the limit position by the threaded rod lower mounting plate. When the separation bin 14 moves upward from the lowest position, it is mainly divided into two stages according to the power source: when the separation bin 14 moves upward from the lowest position, the power for the upward movement in this process mainly comes from the elastic force of the large spring 18 on the threaded rod lower mounting plate 16 when it is reset. When the large spring 18 is fully reset (as shown in the following working step (five), Figure 13), the threaded rod lower mounting plate 16 stops moving upward; the power for the separation bin 14 to continue to move upward and separate from the threaded rod lower mounting plate 16 comes from the elastic force of the small spring 22 when it is fully reset. When the small spring is fully reset, the separation bin 14 reaches the highest position, and the lower threaded rod 15 is completely pulled out of the separation bin 14 (as shown in the following working step (six), Figure 14), and the upper end face of the lower threaded rod 15 is flush with the upper end face of the bottom of the separation bin 14, and the upper end face of the side wall of the separation bin 14 is flush with the upper end face of the side wall of the cleaning bucket 9.

A plurality of limit slides 19 are arranged on the inner wall of the cleaning bucket 9 in a circumferential direction, corresponding to the guide plates I 30 and II 32 one by one. A limit block 36 is fixed on the upper end of the limit slide 19 to limit the highest position of the guide plate I 30 of the separation bin 14 to slide upward, thereby controlling the highest position of the separation bin 14. A plurality of bucket handles 8 are arranged on the upper side of the outer wall of the cleaning bucket 9 to transport the entire separator. A drain port 17 and a drain port cover 10 are arranged at the bottom of the cleaning bucket 9 to discharge waste water after working for a period of time.

Since all parts are in contact with water during operation, they are prone to rust. To prevent the parts from rusting, stainless steel or other hard plastic materials can be used.

The specific working process of the present invention is as follows:

Working steps (a):

Lift the handle tube vertically by hand, the threaded rod upper mounting plate reaches the highest position, and the upper threaded rod is completely separated from the separation chamber. At this time, there is an opening between the threaded rod upper mounting plate and the separation chamber. Pour clean water into the cleaning bucket from the opening, and the water level does not exceed the lower end surface of the threaded lower mounting plate. Then, evenly put the bitter melon seeds with seed coats into the separation chamber from the opening, and the seed quantity should not exceed half the height of the separation chamber (Figure 9).

Working steps (two):

Hold the handle sleeve and press it vertically down. Drive tube I gives the drive head a downward force. The drive head rotates along the spiral part of the metal spiral rod and moves downward at the same time. The drive head drives drive tube I to rotate and move downward synchronously in the support sleeve. Drive tube II is fixed with drive tube I and rotates and moves downward synchronously. Drive tube II drives the threaded rod upper mounting plate to rotate and move downward together. The upper threaded rod rotates and descends under the drive of the threaded rod upper mounting plate. When the upper threaded rod enters the separation chamber, it begins to contact the seeds. The upper threaded rod has relative movement with the stationary seeds, and the seeds begin to be kneaded initially. At this time, there is still a gap between the lower end surface of the bottom of the separation chamber and the lower threaded rod mounting plate. The small spring is in the reset state. The lower threaded rod has not entered the separation chamber yet, and does not participate in kneading the seeds at this stage (Figure 10).

Working steps (three):

Hold the handle sleeve and continue to press down vertically. The action of drive tube I and drive tube II is the same as that of working step (II). The lower end face of the upper threaded mounting plate begins to contact the upper end face of the side wall of the separation bin. At this time, the upper threaded mounting plate and the separation bin form a combined bin body. The guide plate I of the separation bin does not rotate under the restriction of limited sliding. The lower end face of the upper mounting plate of the threaded rod and the upper end face of the side wall of the separation bin are provided with balls and tracks, which greatly reduces the friction resistance of relative rotation. The upper threaded mounting plate rotates while pressing down the separation bin. The lower end face of the bottom of the separation bin begins to compress the small spring. When the lower end face of the bottom of the separation bin contacts the upper end face of the lower mounting plate of the threaded rod, the lower threaded rod enters the separation bin completely. During this process, the lower spiral rod begins to contact the seeds, and the upper and lower threaded rods rotate relative to each other, further kneading the seeds. At this time, the seeds with seed coats gradually form a viscous mixture of seeds and seed coat slurry (Figure 11).

Working steps (four):

Hold the handle sleeve and continue to press it down vertically. The action of drive tube I and drive tube II is the same as that of working step (II). The combined bin body continues to move downward, and the water in the cleaning bucket begins to enter the combined bin body until the combined bin body is completely submerged under water. During this process, the upper and lower threaded rods continue to rotate relative to each other and rub the seeds. The combined bin body moves downward to the lowest position, and the large spring is compressed to the limit position by the mounting plate under the threaded rod. When the sticky seed and seed coating slurry mixture in the combined bin body is mixed with water, the broken seed coating and deflated seeds are stirred by the upper and lower threaded rods, and flow through the sieve holes of the separation bin and the gap between the lower threaded rod and the bottom hole of the separation bin into the cleaning bucket. Clean and full seeds will remain in the combined bin body (Figure 12).

Working steps (five):

Hold the handle and lift the sleeve vertically. Drive tube I gives the drive head an upward force. The drive head rotates along the spiral part of the metal spiral rod (opposite to the direction of work step (II), the same below) and moves upward at the same time. The drive head drives drive tube I to rotate and move upward synchronously in the support sleeve. Drive tube II is fixed with drive tube I and rotates and moves upward synchronously. Drive tube II drives the mounting plate on the threaded rod to rotate and move upward together. The upper threaded rod rotates and rises under the drive of the mounting plate on the threaded rod. The combined warehouse moves upward from the lowest position and gradually moves above the water level. The power for moving upward in this process mainly comes from the support force of the mounting plate under the threaded rod when the large spring is reset. When the large spring is fully reset, the mounting plate under the threaded rod stops moving upward. In this process, the upper and lower threaded rods are constantly rotating relative to each other, rubbing the seeds continuously, and the broken seed coats and deflated seeds enter the cleaning bucket with the water flow (Figure 13).

Working steps (six):

Hold the handle and continue to lift the sleeve vertically. The actions of drive tube I and drive tube II are the same as those in step (V). The combined bin body continues to move upward and gradually separates from the mounting plate under the threaded rod. During this process, the upward force of the separation bin comes from the elastic force of the small spring reset. When the small spring is fully reset and under the action of the limit block, the separation bin reaches the highest position, and the upper end face of the separation bin side wall is flush with the upper end face of the cleaning barrel side wall. The lower threaded rod is pulled out of the separation bin, and the upper end face of the lower threaded rod is flush with the upper end face of the bottom of the separation bin. During this process, the upper and lower threaded rods are constantly rotating relative to each other, kneading the seeds continuously, and the length of the lower spiral rod involved in the operation is gradually shortened to zero (Figure 14).

Working steps (seven):

Hold the handle and continue to lift the sleeve vertically. The action of drive tube I and drive tube II is the same as step (V). During this process, the mounting plate on the threaded rod rotates and rises and gradually separates from the separation chamber. The mounting plate on the threaded rod finally reaches the highest position. At this time, the state is consistent with step (I). If the seed coating is separated cleanly, take out the seed from the opening and start a new round of operation (Figure 15). If the seed coating is not separated cleanly, repeat steps (II) to (VI) and repeat this process.

After multiple operations, if the water in the cleaning bucket is too turbid, you can open the drain cover to drain the waste water. After the waste water is drained, refill it with clean water.
