Description

Technical Field

[0001] This utility model belongs to the field of pomegranate processing technology, and in particular relates to a pomegranate seed separation device. Background Technology

[0002] In the deep processing of pomegranates, the separation and extraction of pomegranate seeds is a crucial step. Traditionally, this relies mainly on manual seed removal, which is inefficient, labor-intensive, and difficult to maintain hygiene. Existing mechanical seed removal devices often use squeezing or rotary stirring methods, which can easily damage the pomegranate seeds, leading to juice loss and affecting product quality and yield. At the same time, because pomegranate seeds are tightly connected to the inner membrane, gravity or vibration alone is often insufficient for complete separation, still requiring manual assistance and preventing continuous, efficient, and automated production. Furthermore, broken pomegranate peel fragments easily mix with the seeds, increasing the difficulty of subsequent sorting. These factors severely restrict the efficiency and development of large-scale pomegranate processing.

[0003] To address these issues, we provide a pomegranate seed separation device. Utility Model Content

[0004] The purpose of this invention is to provide a pomegranate seed separation device. Two conveyor belts are placed on a conveyor platform, with one side of the belts close to the other tilted downwards to form a V-shape. Striking strips are placed on the conveyor belts. A peeling component is located at one end of the conveyor platform. This component cuts the top of the pomegranate and makes segmented cuts on the sides of the pomegranate. The peeled pomegranate is then placed upside down on the two conveyor belts. The conveyor belts push the pomegranate forward while the striking strips strike it downwards, causing the seeds to fall out. The seeds fall through the gap between the two conveyor belts and are collected. The pomegranate shells are then conveyed to the other end by the conveyor belts, thus completing the pomegranate seed separation process.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0021] Please see Figures 1 to 5This utility model relates to a pomegranate seed separation device, comprising a peeling component 1 and a seed-threshing component 2. The seed-threshing component 2 includes a conveying assembly 201 and a striking assembly 202. The conveying assembly 201 includes a conveying platform 201a and two conveyor belts 201b. The two conveyor belts 201b are rotatably mounted above the conveying platform 201a. The sides of the two conveyor belts 201b that are close to each other are inclined downwards to form a V-shape, and a gap is left between the lower sides of the sides of the two conveyor belts 201b that are close to each other. The striking assembly 202 includes striking strips 202a, a set of spring tubes 202b, and a side frame 202c. The side frame 202c is disposed on one side of the conveying platform 201a, the spring tubes 202b are fixedly mounted on one side of the side frame 202c, and the striking strips 202a are disposed on the V-shaped openings of the two conveyor belts 201b. In this invention, a pull rod 202a-1 is vertically fixed at both ends of the upper surface of the striking strip 202a. A sliding plug 202a-2 is fixed at the upper end of the pull rod 202a-1. The two sliding plugs 202a-2 are vertically slidably sleeved in two spring tubes 202b. A compression spring 202b-1 is sleeved inside the spring tube 202b. The two ends of the compression spring 202b-1 are fixedly connected to the upper surface of the sliding plug 202a-2 and the inner top surface of the spring tube 202b, respectively. The peeling component 1 is set at one end of the conveyor table 201a. This invention, by setting a V-shaped conveying channel composed of two inclined conveyor belts 201b, and cooperating with the striking strip 202a above, applies a vertical striking force while conveying the pomegranate, which can effectively shake off the pomegranate seeds and avoid squeezing damage to the seeds.

[0022] Specifically, a drive rod 202a-3 is vertically fixed to the middle section of the upper end face of the striking strip 202a. A drive shaft 202c-1 is sleeved through the plate surface of the side frame 202c. Two rotary push arms 202c-2 are circumferentially arrayed and fixed to the outer wall of one end of the drive shaft 202c-1. A bushing 202c-3 is rotatably sleeved on the outer side of the drive shaft 202c-1. A swing arm 202c-4 is fixed to the outer wall of the bushing 202c-3. A rotary push column 202c-5 is fixed to the end face of the bushing 202c-3. The side wall of the rotary push column 202c-5 fits against the side wall of the rotary push arm 202c-2. The drive rod 202a-3 is vertically sleeved through the horizontal plate on one side of the side frame 202c. A swing rod 202a-4 is hinged to the upper end of the drive rod 202a-3. The end of the swing rod 202a-4 away from the drive rod 202a-3 is hinged to... At the end of the swing arm 202c-4 away from the bushing 202c-3, the drive shaft 202c-1 is connected to the output shaft of the motor via a belt. The motor drives the drive shaft 202c-1 to rotate, and the rotary push arm 202c-2 at one end of the drive shaft 202c-1 pushes the rotary push column 202c-5 to move, thereby causing the bushing 202c-3 to rotate. The bushing 202c-3 drives the swing rod 202a-4, which in turn drives the drive rod 202a-3 to move up and down. When the rotary push arm 202c-2 pushes the rotary push column 202c-5 to the highest point, the rotary push column 202c-5 is no longer pushed by the rotary push arm 202c-2. The compression spring 202b-1 pushes the slide plug 202a-2 downward, causing the striking strip 202a to move downward quickly and strike the pomegranate, causing the pomegranate seeds to detach from the pomegranate shell.

[0023] Furthermore, the peeling component 1 includes a base 101 and a bottom-cutting ring knife 102. The bottom-cutting ring knife 102 is a cylindrical structure with an open top and a closed bottom. The upper surface of the bottom-cutting ring knife 102 is a cutting edge. A rotary motor 102a is arranged below the bottom-cutting ring knife 102. The output end of the rotary motor 102a is fixedly connected to the lower surface of the bottom-cutting ring knife 102. The rotary motor 102a is arranged above the base 101. The rotary motor 102a drives the bottom-cutting ring knife 102 to rotate, so that the bottom-cutting ring knife 102 can quickly and neatly cut annular marks at the bottom of the pomegranate, preparing for the subsequent segmentation and threshing processes.

[0024] Furthermore, a pressing cylinder 101a is provided above the base 101. A fixed sleeve 101a-1 is fixedly installed at the lower telescopic end of the pressing cylinder 101a. A set of fixing tags 101a-2 is fixedly provided on the inner top surface of the fixed sleeve 101a-1. When the pomegranate is placed inside the fixed sleeve 101a-1, the fixing tags 101a-2 move down and pierce into the pomegranate, thereby achieving reliable fixation of the pomegranate. The pressing cylinder 101a pushes the pomegranate downward, causing the pomegranate to be pushed towards the bottom-cutting ring knife 102 below.

[0025] Furthermore, a spring cylinder 101b is provided below the pedestal 101. The upper end of the spring cylinder 101b penetrates the table surface of the pedestal 101. A vertical sliding sleeve 102a-1 is provided at the lower end of the rotary motor 102a. The vertical sliding sleeve 102a-1 is slidably sleeved inside the spring cylinder 101b. An upper top spring 101b-1 is sleeved inside the spring cylinder 101b. The two ends of the upper top spring 101b-1 are respectively fixedly connected to the inner bottom surface of the spring cylinder 101b and the lower bottom surface of the vertical sliding sleeve 102a-1.

[0026] Furthermore, a set of segmented blade holders 101c are fixedly mounted in a circumferential array on the upper end face of the pedestal 101. A blade slide tube 101c-1 is fixedly mounted on the upper end of each segmented blade holder 101c. The axis of the slide tube 101c-1 is perpendicular to the pedestal 101. The end of the slide tube 101c-1 away from the axis of the pedestal 101 is closed. A blade holder 101c-2 is slidably sleeved inside the slide tube 101c-1. A segmented blade 101c-3 is fixedly mounted on the end face of the blade holder 101c-2 near the axis of the pedestal 101. The blade surface of the segmented blade 101c-3 is perpendicular to the horizontal plane. The end of the segmented blade 101c-3 away from the blade holder 101c-2 has an upward-facing inclined surface, which is the cutting edge. A side-top spring 101c-4 is fitted inside the slide tube 101c-1. The two ends of the side-top spring 101c-4 are fixedly connected to the inner bottom surface of the slide tube 101c-1 and the end face of the cutter seat 101c-2, respectively. When the bottom-cutting ring cutter 102 cuts into the bottom of the pomegranate, the downward-pressing cylinder continues to push the pomegranate downward, causing the vertical slide sleeve 102a-1 to press down on the upper-top spring 101b-1, thereby causing the pomegranate to continue to move downward. During the downward movement of the pomegranate, the surrounding splitting cutters 101c-3 cut the pomegranate shell with splitting marks. At the same time, as the pomegranate moves downward, the splitting cutters 101c-3 continuously compress the side-top spring 101c-4 to prevent the splitting cutters 101c-3 from cutting too deeply.

[0027] The operation process of this embodiment is as follows: First, the pomegranate is placed inside the fixed sleeve 101a-1, causing the fixed tag 101a-2 to move down and pierce the pomegranate. The pressing cylinder 101a is activated to press down, pushing the pomegranate towards the bottom-cutting ring knife 102, causing the bottom-cutting ring knife 102 to cut into the bottom shell of the pomegranate. Then, the rotary motor 102a drives the bottom-cutting ring knife 102 to rotate and move down, removing annular cuts on the bottom of the pomegranate. Next, the pressing cylinder 101a continues to push downward, causing the vertical sliding sleeve 102a-1 to press down on the upper spring 101b-1, thereby causing the pomegranate to continue to move downward. During the downward movement of the pomegranate, the surrounding segmenting knives 101c-3 cut segmented cuts into the pomegranate shell. At the same time, as the pomegranate moves downward, the segmenting knives 101c-3 do not... The compression side top spring 101c-4 is broken to prevent the splitting knife 101c-3 from cutting too deeply; after the peeling and splitting are completed, the pressing cylinder 101a is reset, the pomegranate is taken out, the bottom skin of the pomegranate is manually peeled off along the pomegranate's annular cut, and then part of the outer skin is peeled off along the side cut. Then the pomegranate is placed upside down on the V-shaped conveyor belt 201b of the threshing unit 2; the drive motors of the conveyor belt 201b and the striking component 202 are started, the conveyor belt 201b carries the pomegranate forward, and at the same time the drive shaft 202c-1 drives the striking strips 202a to continuously move up and down through the transmission mechanism, which elastically strikes the passing pomegranate, causing the pomegranate seeds to fall and fall through the gaps between the conveyor belts 201b for collection, while the empty pomegranate shells are conveyed to the end for discharge.
