Description

Technical Field

[0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a device for sorting and shelling sour jujube kernels. Background Art

[0002] Jujube, a woody plant of the genus Jujube in the family Rhamnaceae. It grows on sunny hillsides and roadsides, and is mainly produced in Henan, Hebei, Shaanxi, Liaoning, Shanxi, Shandong, Yunnan and other places. The fruit is harvested in autumn when it is ripe, and the pulp is removed to obtain the jujube kernel. The hard jujube kernel is broken to obtain the seeds, and the jujube kernel can be obtained. The jujube kernel can nourish the liver, calm the mind, soothe the nerves, and restrain sweating. It can treat symptoms such as insomnia, palpitations, spontaneous sweating and night sweats. Not only can the jujube kernel be used as medicine, but the hard core of the jujube also has a certain value for playing with. The jujube kernel is oblate or oval, and the yield of round kernels is very small. The size range is 5~9mm long, 5~7mm wide, and about 3mm thick. The jujube kernel with good appearance can be made into a hand string for playing with. The characteristics of the jujube kernel in the hand string for playing with are large eyes and beautiful patterns. The size of the jujube kernel hand string for playing with the general appearance is about 7.5mm. The larger and rounder the jujube kernel, the more expensive it is.

DETAILED DESCRIPTION

[0018] In order to better understand the present invention, the content of the present invention is further clearly set forth in conjunction with the embodiments below, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are provided in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0019] A device for sorting and shelling jujube kernels, comprising a spiral conveying device 1, a sorting device 2, a shelling device 3, a screening device 4, a device body 5 and a side shield 6; the lower part of the spiral conveying device 1 is sleeved and fixed in the opening above the side shield 6; the sorting device 2 is fixedly arranged inside the side shield 6, and a power transmission port 601 is opened on the side; the sorting device 2 is connected to a first driving motor 502 fixed on the device body 5 by a belt 501 passing through the power transmission port 601; a slotted funnel 602 is integrally fixedly connected below the side shield 6; a shelling device 3 mounted on the device body 5 is arranged below the slotted funnel 602, and a screening device 4 is fixedly arranged below the shelling device 3.

[0020] Preferably, the spiral conveying device 1 comprises a second driving motor 101, a spiral blade conveying rod 102, a conical silo 103, a silo shield 104 and a discharge channel 105; the lower part of the conical silo 103 is sleeved and fixed in the opening above the side shield 6, and one end of the discharge channel 105 is fixedly connected to the cone tip of the conical silo 103; a semi-enclosed silo shield 104 is fixedly provided on the upper part of the conical silo 103; the second driving motor 101 is fixedly provided on the silo shield 104; the power output shaft end of the second driving motor 101 is drivingly connected to the spiral blade conveying rod 102; the spiral blade conveying rod 102 extends into the discharge channel 105. The other end of the discharge channel 105 is fixedly connected to an arc-shaped flat groove-shaped discharge port 106 that is provided in a clearance matching with the surface of the sorting disk 201.

[0021] The implementation method of feeding by spiral blades can linearly adjust the feeding speed and accurately control the sorting effect of the sorting disk 201 in the next stage. The spiral blade conveying rod 102 extends into the discharge channel 105 to further accurately control the state of the jujube kernel when it enters the sorting disk 201, thereby reducing the vertical speed of the jujube kernel when it enters the sorting disk 201; the design of the arc-shaped flat groove-shaped discharge port 106 of the discharge channel further changes the movement direction of the jujube kernel when it enters the sorting disk 201, so that it can be consistent with the tangent direction of the rotation of the sorting disk 201. The flat groove shape can further reduce the drop impact generated when the jujube kernel rolls into the sorting disk 201, thereby changing the movement posture of the jujube kernel and affecting the sorting effect.

[0022] Preferably, the sorting device includes a sorting disc 201, a leakage port 202, a guide plate 203, a bearing 204, a leakage screen plate 205 and a sorting transmission hollow shaft 206; the leakage screen plate 205 is tiltedly arranged inside the side shield 6 and fixedly connected thereto; a discharge port 603 is provided on the side shield 6 at the lowest point of the inclination of the leakage screen plate 205; the bearing 204 passes through the leakage screen plate 205 and is fixedly arranged at its center; a sorting transmission hollow shaft 206 is fixedly sleeved inside the bearing 204; the sorting transmission hollow shaft 206 is connected to the first drive motor 502 fixed on the equipment body 5 by a belt passing through the power transmission port 601; a conical sorting disc 201 is fixedly arranged at the leakage port 202 on the upper end of the sorting transmission hollow shaft 206; the other end of the discharge channel 105 is gapped with the conical sorting disc 201.

[0023] Preferably, the sieve hole diameter of the sieve plate 205 is 6.8 mm-7.2 mm.

[0024] By obliquely setting the sieve plate 205 inside the side shield 6, the size of the jujube pits that have been screened for roundness by the sorting disk 201 can be screened again. The small-sized and well-rounded jujube pits that do not meet the screening conditions will be screened out and enter the shell breaking and kernel extraction stage; the large-sized and well-rounded jujube pits that meet the screening conditions will roll towards the discharge port 603 under the action of gravity.

[0025] Preferably, the discharge direction of the discharge channel 105 is consistent with the rotation tangent direction of the sorting disk 201; a guide plate 203 is provided on the side opposite to the discharge direction of the discharge channel 105; the guide plate 203 is fixedly connected to the side shield 6 with a clearance fit with the upper surface of the sorting disk 201.

[0026] The guide plate 203 is used to guide the oblate or elliptical sour jujube kernels that have not fallen off the sorting disk 201 under the action of centrifugal force and have not passed through the leakage port 202 in time and through the sorting transmission hollow shaft 206 to enter the shell breaking and kernel taking process, so as to guide them into the leakage port 202 and prevent them from continuing to rotate with the sorting disk 201, thereby affecting and interfering with the ongoing sorting work.

[0027] Preferably, the shell breaking device 3 includes a first crushing tooth roller 301, a second crushing tooth roller 302, a first gear 303, a second gear 304 and a third drive motor 305; the first crushing tooth roller 301 and the second crushing tooth roller 302 are respectively mounted inside the equipment body 5 through two rotating shafts 306 passing through rotating shaft bearings 307 fixedly arranged on opposite sides of the equipment body; a pair of gears meshing and connected to each other are fixedly arranged at both ends of the two rotating shafts 306, and one gear at one end is connected to the third drive motor 305; the first crushing tooth roller 301 and the second crushing tooth roller 302 are arranged with a gap, and the gap extending between the two along the length direction is directly below the notch arranged along the length direction of the notch funnel 602.

[0028] The first crushing tooth roller 301 and the second crushing tooth roller 302 are set with a gap of 4.8mm-5.2mm. The way of setting the gap between the crushing tooth rollers can achieve efficient crushing of the shell of the sour jujube pit while reducing the damage to the sour jujube kernel in the sour jujube pit.

[0029] The rotating shaft 306 is fixedly connected to the gear disposed outside the device body 5, and then the power transmission is provided through the gear meshing. If the gap between the two crushing tooth rollers is too wide, the sour jujube kernels in the sour jujube kernels will not be completely crushed, and if it is too narrow, the sour jujube kernels in the sour jujube kernels will be damaged, affecting the appearance. In this way, the relative position between the two crushing tooth rollers will not be offset due to the vibration generated when the sour jujube kernels are crushed, which ensures the fixation of the relative position between the two crushing tooth rollers, thereby improving the crushing effect.

[0030] Preferably, the screening device 4 includes a vibrating screen 401, a connecting plate 402, a positioning column 403, and a vibration source motor 404; the vibrating screen 401 is arranged directly below the fitting gap extending along the length direction between the first crushing tooth roller 301 and the second crushing tooth roller 302; at least three groups of mutually corresponding cam shafts 405 are fixedly arranged on both sides of the vibrating screen 401, and the rotating shaft of the cam shaft 405 is connected to one end of the connecting plate 402, the other end of one of the connecting plates 402 is fixedly connected to the power output shaft end of the vibration source motor 404, and the other end of the other connecting plates 402 is connected to the rotating shaft of the positioning column 403 fixedly arranged on the equipment body.

[0031] The screening device 4 can screen the mixture after the jujube kernels are broken by the shell breaking device 3, mainly screening out the small pieces of jujube kernel residues and scum in the mixture, and can also simply screen and partition the large pieces of jujube kernel residues and jujube kernels in the vibrating screen 401.

[0032] Furthermore, the spiral blade conveying rod 102 is fixedly connected with a disturbance member 107 around the conical silo 103. The disturbance member 107 can disturb the jujube kernels to be processed in the conical silo 103, so that the jujube kernels in the conical silo 103 rub against each other, achieving a ball-milling-like effect, further improving the roundness of the jujube kernels, and reducing the influence of the protruding parts of the jujube kernels through friction as much as possible, thereby enhancing the effects of sorting, screening, and shelling.

[0033] Furthermore, the upper surface of the sorting disc 201 is made of energy-absorbing friction silica gel material. This method further improves the friction of the sorting disc 201 and further reduces the connection stability when the sour jujube kernels enter the sorting disc 201 from the discharge channel, reduces the generation of vibration, and ensures that the discharge direction is controlled and consistent.

[0034] Furthermore, a belt guard 604 is provided on the outer protective cover of the belt inside the side guard 6; one end of the belt guard 604 is fixedly connected to the bearing 204, and the other end is fixedly connected to the side guard 6 at the power transmission port 601; a guide block 605 is fixedly provided at the position of the belt guard 604 below the sorting disk 201. The guide block 605 can prevent the sour jujube kernels falling on the belt guard 604 from moving further to the power connection point between the belt 501 and the sorting transmission hollow shaft 206, and guide the sour jujube kernels to fall on the sieve plate 205 to both sides, so as not to affect the sorting stability of the sorting disk 201.

[0035] When in use, firstly, the jujube kernels to be processed are put into the conical silo 103, and the first drive motor 502, the second drive motor 101, the third drive motor 305 and the excitation source motor 404 are started; the disturbance member 107 performs disturbance friction on the jujube kernels to be processed in the conical silo 103, and the spiral blade conveying rod 102 conveys the jujube kernels to the discharge channel 105, passes through the arc-shaped flat groove-shaped discharge port 106 and rolls into the sorting disk 201 along the tangential direction of the sorting disk 201. The speed at which the sour jujube pits with good roundness roll out is faster than that of the oval sour jujube pits. The upper surface of the sorting disk 201 made of energy-absorbing friction silicone material can prevent the movement trend of the sour jujube pits with good roundness from changing significantly in the rolling direction. Combined with the rotation speed of the sorting disk 201, the sour jujube pits with good roundness will be quickly thrown out of the sorting disk 201 under the action of centrifugal force and fall on the sieve plate 205. The sour jujube pits with appropriate roundness and size that meet the requirements will roll towards the discharge port 603 under the action of gravity; the sour jujube pits with appropriate roundness but too small size will be screened out and fall into the slot funnel 602.

[0036] The initial velocity of the elliptical or oblate jujube kernels rolling out of the arc-shaped flat groove-shaped discharge port 106 of the discharge channel is slow. Under the combined influence of the friction provided by the upper surface of the sorting disk 201 made of energy-absorbing friction silicone material, the shape of the elliptical or oblate jujube kernels themselves and the rotating sorting disk 201, the movement direction and trend of the jujube kernels change, and the initial velocity decays rapidly, so that they fall into the leakage port 202, enter the sorting transmission hollow shaft 206, and fall into the slot funnel 602.

[0037] The sour jujube kernels falling into the slotted funnel 602 will be caught in the gap between the first crushing tooth roller 301 and the second crushing tooth roller 302. As the sour jujube kernels rotate, their shells will be squeezed and broken by the crushing tooth rollers rotating in opposite directions. The broken sour jujube kernel shells and sour jujube kernels will fall into the vibrating screen 401 together. The small pieces of sour jujube kernel residues and scum in the mixture will be screened out, and the sour jujube kernels and sour jujube kernels with simple stratification and partitioning can be obtained.

[0038] Compared with the prior art, the present invention realizes the efficient and rapid sorting of different specifications of sour jujube kernels, thereby realizing the multi-directional development of sour jujube and bringing higher economic value. Moreover, the sour jujube kernels of large specifications are sorted out in advance, and the size specifications of the sour jujube kernels to be shelled and kerneled are relatively unified, which is more beneficial to the subsequent shelling and kerneling work. It can greatly reduce the probability of damage to the sour jujube kernels during the shelling and kerneling process of large-size sour jujube kernels, and realize economical and efficient production.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in the field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
