Description

Technical Field

[0001] This invention relates to the field of shell-breaking and sorting devices, specifically a multi-stage shell-breaking and sorting device for processing jujube kernels. Background Technology

[0002] Sour jujube seed, the seed of the sour jujube plant (Rhamnaceae family), has extremely high medicinal value. It is sweet and sour in nature and neutral in taste. It can nourish the heart and liver, calm the mind and soothe the nerves, astringe sweat and promote body fluid production. It has significant effects on symptoms such as insomnia due to deficiency and restlessness, palpitations and dreaminess, excessive sweating due to physical weakness, and thirst due to fluid depletion. It is widely used in the medical field. In the traditional processing of sour jujube seed, after the sour jujube is harvested and the pulp is removed, the sour jujube kernel is obtained. Then, the sour jujube kernel needs to be cracked to obtain the sour jujube seed. This requires the use of a corresponding cracking and sorting device.

[0003] Currently, when using the shell-breaking and sorting equipment for jujube kernel processing, operators manually crush the jujube kernels one by one with a hammer. This method not only requires operators to have certain skills, but also involves extremely high labor intensity. Alternatively, mechanical equipment can be used for one-time roller crushing. If the jujube kernels are of different sizes, or if they overlap during one-time feeding and roller crushing, it may result in the jujube kernels being difficult to crush in one go, or the jujube kernels being damaged due to excessive force in one go, thus reducing the yield of the finished product.

[0004] To address the above problems, a multi-stage shell-breaking and sorting device for processing jujube kernels is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-stage shell-breaking and sorting device for processing jujube kernels. By using this device, the problem of using manual or mechanical equipment for one-time roller crushing, which may result in the jujube kernels being difficult to crush in one go or being damaged due to excessive force, is solved, thereby reducing the yield of the finished product.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage shelling and sorting device for processing jujube kernels, comprising a working frame and a shelling mechanism.

[0010] Furthermore, the driven gear is rotatably connected to the intermittent gear through the second gearbox, the sliding block is elastically connected to the support guide post through the compression spring, and the sliding block is slidably connected to the support guide post, while the support guide post is fixedly connected to the shell-breaking seat.

[0011] Furthermore, a sorting mechanism for sorting is provided on one side of the work frame. The sorting mechanism includes a sorting frame, a power shaft, a first sorting roller, and a second sorting roller. The power shaft is installed in the middle of the sorting frame, and the first sorting roller is installed at the outer front end of the power shaft. The second sorting roller is provided behind the first sorting roller, and the aperture of the first sorting roller is smaller than the aperture of the second sorting roller.

[0012] Furthermore, the sorting mechanism also includes a discharge slide plate, a reciprocating screw, and a sliding seat. A discharge slide plate is provided below both the first and second sorting rollers. A reciprocating screw is installed at the middle of the rear end of the power shaft, and a sliding seat is installed at the middle of the surface of the reciprocating screw. The reciprocating screw is integrated with the power shaft.

[0013] Furthermore, the sorting mechanism also includes a connecting frame, a first roller cylinder, and a second roller cylinder. The connecting frame is fixed to the middle of both sides of the sliding seat, and the second roller cylinder is fixed to the front end of the connecting frame. The first roller cylinder is fixed to the front end of the second roller cylinder, and there is a certain gap between the first roller cylinder and the second roller cylinder and the first sorting cage and the second sorting cage.

[0014] Furthermore, a cleaning mechanism for re-pressing and cleaning is provided on the lower inner part of the upper part of the work frame. The cleaning mechanism includes a synchronous extrusion roller, a second reduction motor and a support frame. The input end of the synchronous extrusion roller is equipped with a second reduction motor, and support frames are installed on both sides below the synchronous extrusion roller.

[0015] Furthermore, the cleaning mechanism also includes a contact baffle and an elastic rotating seat. The contact baffle is installed on the lower part of the inner side of the support frame, and the elastic rotating seat is installed at the bottom of the contact baffle. The contact baffle is elastically connected to the support frame through the elastic rotating seat.

[0016] Furthermore, the cleaning mechanism also includes an abutting scraper, a receiving bin, a cover plate, and a fixing rod. An abutting scraper is provided on the upper side of one side of the support frame, and the abutting scraper is in contact with the surface of the synchronous extrusion roller. A receiving bin is installed on the inner side of the support frame, and a cover plate is installed on one side surface of the receiving bin. A fixing rod is fixed in the middle of one side of the cover plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention utilizes a shell-removing mechanism to pre-crack the hard jujube pits using a pressing receiving seat. Subsequently, fixed protrusions and an impact head continuously apply secondary pressure and impact to the jujube pits, allowing them to undergo a process of loosening the hard shell through compression before being impacted to break the shell. This achieves a multi-stage shell-breaking process, ensuring stable shell breaking while avoiding excessive force and adhesion or even damage to the jujube kernel caused by a single high-pressure process. The use of an independent receiving seat for conveying also avoids uneven compression or damage caused by overlapping forces due to material accumulation. Furthermore, the impact force of the impact head helps to disperse and separate the broken jujube pits, reducing the possibility of the pits sticking to the receiving seat and the jujube kernel. Additionally, the radially distributed, annular fixed protrusions that rotate with the inner cylinder prevent excessive wear from a single row of fixed protrusions during compression, ensuring a long-lasting and effective compression effect.

[0019] 2. This invention uses a sorting mechanism to apply a certain amount of kneading force to the jujube kernels after they have been cracked. At the same time, it uses flexible silicone material to protect the jujube kernels and reduce damage. This allows for the kneading and removal of any remaining jujube shell material of a certain thickness that may have not been completely removed from the surface after cracking. This helps to improve the cleanliness of the final product and avoids the adhesion of impurities and debris, which would be difficult to handle and affect the yield of the jujube kernels.

[0020] 3. The present invention, through a cleaning mechanism, further enables the jujube kernels to undergo a three-stage process of extrusion, impact, and extrusion cracking, which helps to further improve the cracking effect, ensure product yield, and continuously scrape off impurities and mud adhering to the surface of the synchronous extrusion rollers. The scraped impurities and mud can fall into the receiving hopper for collection. This continuous cleaning of the surface of the synchronous extrusion rollers can prevent the problem of the synchronous extrusion roller gap narrowing due to the long-term adhesion of impurities, which affects the stability of cracking.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] To address the technical issue of how single-stage roller crushing using manual or mechanical equipment can lead to problems such as difficulty in crushing jujube pits or damage to jujube kernels due to excessive stress, thus reducing the yield of the finished product, the following measures are proposed. Figures 1-6 As shown, the following preferred technical solutions are provided:

[0034] A multi-stage shelling and sorting device for processing jujube kernels includes a working frame 1 and a shelling mechanism 2 disposed inside the upper part of the working frame 1. The working frame 1 includes a shelling seat 101 disposed on one side of the upper part of the working frame 1. An inlet 102 is provided on the upper side of the shelling seat 101, and a processing trough 103 is opened in the middle of the inner side of the shelling seat 101. A power lever 104 is provided on the upper side of the processing trough 103. A vibrating screen 105 is installed at the bottom of the processing trough 103. A power motor is installed at the input end of the power lever 104 to drive its rotation, so that the rotating power lever 104 can disperse the jujube kernel material added from the inlet 102 into the processing trough 103, thereby preventing the jujube kernels from accumulating and making it difficult to feed the material stably.

[0035] The shell removal mechanism 2 includes a receiving roller 201 disposed in the middle of the processing tank 103. A receiving groove 202 is provided in the middle of the surface of the receiving roller 201, and a fixed tooth ring 203 is fixed on both ends of the receiving roller 201. A drive gear 204 is meshed on one side of the fixed tooth ring 203, and a first reduction motor 205 is installed at the input end of the drive gear 204.

[0036] A first gearbox 206 is installed below the front end of the first gear motor 205, and a rotating inner cylinder 207 is connected to the lower front end of the first gearbox 206. A fixing protrusion 208 is fixed on the surface of the rotating inner cylinder 207. A receiving seat 209 is installed below the inner side of the receiving groove 202, and elastic supports 210 are installed on both sides below the receiving seat 209. A driven gear 211 meshes with one side of the fixed gear ring 203, and a second tooth is provided at the front end of the driven gear 211. The gearbox 212 has an intermittent gear 213 connected to one side above it. A fixed rack 214 meshes with the upper part of the intermittent gear 213. A sliding block 215 is fixed above the fixed rack 214. A support guide post 216 passes through the middle of the sliding block 215. A compression spring 217 is provided at the rear middle of the sliding block 215. A connecting plate 218 is fixed at the middle of one side of the sliding block 215. An impact head 219 is fixed on the front surface of the connecting plate 218.

[0037] The receiving roller 201 is rotatably connected to the processing tank 103, and the drive gear 204 is rotatably connected to the first reduction motor 205. The first reduction motor 205 is rotatably connected to the rotating inner cylinder 207 through the first gearbox 206. The receiving seat 209 is elastically connected to the receiving roller 201 through the elastic support 210. The receiving tank 202, the receiving seat 209 and the elastic support 210 are arranged in a ring about the receiving roller 201.

[0038] Driven gear 211 is rotatably connected to intermittent gear 213 via second gearbox 212. Sliding block 215 is elastically connected to support guide post 216 via compression spring 217. Sliding block 215 is slidably connected to support guide post 216. Support guide post 216 is fixedly connected to shell breaker 101.

[0039] The first reduction motor 205 and the drive gear 204 drive the fixed gear ring 203 and the receiving roller 201 to rotate within the processing tank 103. Multiple sets of receiving grooves 202, arranged annularly and equidistantly on the surface of the receiving roller 201, individually receive the jujube pits. As the receiving roller 201 rotates clockwise, it carries the jujube pits from the receiving grooves 202 into the processing tank 103. The first gearbox 206, connected to the conveying shaft of the first reduction motor 205, converts the rotation to drive the inner rotating cylinder 207 to rotate. The inner rotating cylinder 207 rotates faster than the receiving roller 201, ensuring that the fixed protrusions 208 on the inner rotating cylinder 207 pass through the receiving grooves one by one during rotation. The receiving seat 209 corresponding to 202 allows the fixed protrusion 208, which is set in an arc shape at the top, to push the receiving seats 209 one by one upward when it passes the receiving groove 202 on the lower arc surface. This allows the pushed receiving seats 209 to cooperate with the inner wall of the processing groove 103 to exert a certain squeezing and cracking force on the jujube pits in the receiving seats 209, so as to pre-crack the hard jujube pits. After squeezing, the elastic support 210 can pull the receiving seat 209 back, so that the pre-cracked jujube pits can continue to be rotated. At the same time, the fixed protrusions 208, which are arranged in multiple rings in the radial direction and can rotate with the rotating inner cylinder 207, can also avoid the wear problem of excessive consumption of single-row fixed squeezing during squeezing, so as to ensure a long-term effective squeezing effect.

[0040] When the pre-cracked jujube pits are moved to the middle of the side wall of the processing tank 103, the rotating fixed gear ring 203 drives the driven gear 211 to rotate. After a specific speed increase through the second gearbox 212, it eventually drives the intermittent gear 213 to rotate. When the intermittent gear 213 rotates, it can push the sliding block 215 under the push of the fixed rack 214, thus pressing the compression spring 217. When the receiving seat 209 rotates to the side perpendicular to the sliding block 215, the intermittent gear 213 separates from the fixed rack 214. At this time, the sliding block 215, the connecting plate 218, and the impact head 219 will be rapidly ejected forward by the rebound force of the compression spring 217, so that a row of impact heads 219, which are set in equal numbers to the receiving seat 209, can perform a secondary impact cracking process on the jujube pits in the receiving seat 209. Furthermore, the impact stroke of the impact head 219 is slightly greater than the distance from the jujube kernel to the bottom of the receiving seat 209. During the impact, the elastic support 210 can also absorb the excessive impact force to prevent damage to the jujube kernel. Thus, during the rotation of the receiving roller 201, the fixed protrusion 208 and the impact head 219 continuously apply pressure and impact to the jujube kernel in the receiving seat 209, allowing the jujube kernel to undergo the process of squeezing and loosening the hard shell before impacting and breaking the shell. This achieves multi-stage shell breaking. While ensuring stable shell breaking, the multi-stage shell breaking process can also avoid the problem of excessive force and adhesion or even damage to the jujube kernel caused by one-time high pressure. At the same time, the use of an independent receiving seat 209 for conveying also avoids the problem of uneven squeezing or damage caused by material accumulation or overlapping force.

[0041] To address the technical problem of jujube kernel shell fragments easily adhering to the surface after cracking and being difficult to remove, thus affecting the quality and yield of the finished product, such as... Figure 1 , Figure 7 and Figure 8 As shown, the following preferred technical solutions are provided:

[0042] A sorting mechanism 3 for sorting is provided on one side of the working frame 1. The sorting mechanism 3 includes a sorting frame 301 located on one side below the shell breaking seat 101. A power shaft 302 is installed in the middle of the sorting frame 301, and a first sorting roller 303 is installed at the outer front end of the power shaft 302. A second sorting roller 304 is provided behind the first sorting roller 303, and the aperture of the first sorting roller 303 is smaller than the aperture of the second sorting roller 304.

[0043] The first sorting roller 303 and the second sorting roller 304 are both provided with a discharge slide plate 305. A reciprocating screw 306 is installed in the middle of the rear end of the power shaft 302, and a sliding seat 307 is installed in the middle of the surface of the reciprocating screw 306. The reciprocating screw 306 and the power shaft 302 are integrated. A power motor is provided at the input end of the power shaft 302, which can drive it to rotate.

[0044] A connecting frame 308 is fixed at the middle of both sides of the sliding seat 307, and a second roller 310 is fixed at the front end of the connecting frame 308. A first roller 309 is fixed at the front end of the second roller 310, and there is a certain gap between the first roller 309 and the second roller 310 and the first sorting cage 303 and the second sorting cage 304.

[0045] After being processed by the vibrating screen 105, the jujube pits, having undergone shell breaking, fall into the gap between the first sorting cylinder 303 and the first roller 309. The front end of the first roller 309 is closed, and the gap between the first roller 309 and the first sorting cylinder 303 is the same as the spacing of the feed grid of the first sorting cylinder 303. Similarly, the gap between the second roller 310 and the second sorting cylinder 304 is the same as the spacing of the feed grid of the second sorting cylinder 304. When the power shaft 302 drives the first and second sorting cylinders 303 and 304 to rotate and screen the material, the reciprocating screw 306 drives the sliding seat 307 and the connecting frame 308 to move back and forth, thereby causing the first roller 309 and the second roller 310 to move back and forth. The first sorting roller 303 and the second sorting roller 304 move back and forth, thereby relying on the rotation of the first sorting roller 303 and the back and forth movement of the first sorting roller 303 and the second sorting roller 304 to exert a certain kneading force on the jujube kernels in the gap. At the same time, the outer surfaces of the first roller 309 and the second roller 310, as well as the first sorting roller 303 and the second sorting roller 304, are all provided with flexible silicone material to protect the jujube kernels and reduce damage. This can knead and remove the jujube shell material with a certain thickness that may not be completely removed after the shell is broken, thereby improving the cleanliness of the subsequent jujube kernel finished product and avoiding the adhesion of impurities and debris that are difficult to handle and affect the yield of jujube kernels.

[0046] To address the technical problems of incomplete shell cracking of jujube pits and the tendency for impurities to adhere and affect the stability of the cracking process, such as... Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown, the following preferred technical solutions are provided:

[0047] A cleaning mechanism 4 for re-pressure cleaning is provided on the lower inner part of the upper part of the work frame 1. The cleaning mechanism 4 includes a synchronous extrusion roller 401 located in the middle of the lower part of the processing tank 103. A second reduction motor 402 is installed at the input end of the synchronous extrusion roller 401, and support frames 403 are installed on both sides below the synchronous extrusion roller 401. The synchronous extrusion roller 401 is located directly below the receiving roller 201.

[0048] A fitting baffle 404 is installed on the lower side of the inner side of the support frame 403, and an elastic rotating seat 405 is installed at the bottom of the fitting baffle 404. The fitting baffle 404 is elastically connected to the support frame 403 through the elastic rotating seat 405.

[0049] A scraper 406 is provided on one side of the support frame 403, and the scraper 406 is in contact with the surface of the synchronous extrusion roller 401. A receiving bin 407 is installed on one side of the inside of the support frame 403, and a cover plate 408 is installed on one side surface of the receiving bin 407. A fixing rod 409 is fixed in the middle of one side of the cover plate 408.

[0050] The second reduction motor 402 and the reduction gearbox drive the two sets of synchronous extrusion rollers 401 to rotate in opposite directions. Material falling from below the processing tank 103 after being impacted by the receiving seat 209 will fall into the middle gap of the synchronous extrusion rollers 401. This gap is larger than the size of a jujube kernel but smaller than the size of a whole jujube pit, allowing jujube pits that haven't been properly shelled to continue being shelled. The shelled jujube kernels will fall directly through the gap, further enhancing the shelling effect through a three-stage process of extrusion, impact, and extrusion shelling. This ensures a higher product yield. The adhesive baffle 404 and the elastic rotating seat 405 can further enhance the shelling effect of the synchronous extrusion rollers 401. 1. When impurities adhere to the working surface for a long time, as the synchronous extrusion roller 401 rotates, the elastic deformation of the contact baffle 404 can transfer the surface of the synchronous extrusion roller 401 to between the contact baffle 404 and the contact scraper 406. As the synchronous extrusion roller 401 rotates continuously, the contact scraper 406 can continuously scrape off the impurities and mud adhering to the surface of the synchronous extrusion roller 401, so that the scraped impurities and mud can fall into the receiving bin 407 for collection. Through the fixed pull rod 409 and the cover plate 408, the collected impurities can be periodically extracted and cleaned. This continuous cleaning of the surface of the synchronous extrusion roller 401 can avoid the problem of the gap of the synchronous extrusion roller 401 becoming smaller due to the long-term adhesion of impurities, which affects the stability of shell breaking.
