Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery, specifically relating to a device for edge rolling and shaping of plastic container bags. Background Technology

[0002] Walnut trees are highly adaptable and are cultivated in more than 20 provinces, municipalities, and autonomous regions across China. my country has the largest walnut cultivation area in the world. After harvesting green walnuts, the green husk should be removed from the nuts as soon as possible to ensure that the walnut shells are clean and bring higher economic value.

[0003] Currently, there are four methods for peeling green walnuts: manual peeling, composting peeling, chemical peeling, and mechanical peeling.

[0004] Manual peeling is the most common method. The green husk of the walnut is gently tapped with a stick, or a large piece of green husk is peeled off with a hand scraper. Then, a brush dipped in water is used to scrub away any remaining husk. During this process, a substance called "walnut husk extract" seeps out, staining the skin a difficult-to-wash black color, and requires a lot of manual labor.

[0005] The composting method is a traditional Chinese method for peeling walnuts. Harvested green-skinned walnuts are transported to a cool, shady place and piled up to a thickness of about 50cm. To accelerate the dehydration of the green husks, a layer of dry grass or leaves about 10cm thick can be added to the pile to raise the temperature inside. After 3-5 days, when more than 50% of the green husk has separated from the shell or cracked, it can be peeled off by tapping it with a stick. This method is difficult to control in terms of timing, has low efficiency, and a high rate of fruit contamination, significantly impacting the commercial quality of the walnuts.

[0006] The chemical peeling method uses a 0.3%–0.5% ethephon solution to ripen green walnuts. The green walnuts are dipped in the solution for half a minute, then piled in a cool, shady place or indoors. Under conditions of 30℃ and 80%–95% relative humidity, the peeling rate can reach over 95% after about 5 days. This method is fast, but it damages the environment and causes pollution.

[0007] With the development of science and technology, mechanical peeling methods are becoming increasingly popular. The methods that can achieve mechanical peeling include: (1) using a high-speed rotating cutting blade and a roller to complete the peeling work. This method has a simple structure and strong versatility, but it has the disadvantages of incomplete peeling and a high breakage rate, such as Publication No.: CN210329261U (Green Walnut Peeling and Cleaning Machine). (2) using a rotating wire brush and a cylindrical screen to complete the peeling work. This method peels the walnuts by friction, reducing the breakage rate, but the green skin brushed off is difficult to collect, causing environmental pollution and requiring a large amount of water resources, resulting in resource waste, such as Publication No.: CN203467619U (A Green Walnut Peeling Machine). (3) using a wear-resistant rubber roller and a peeling cutter to complete the peeling work. This method has a simple structure and high peeling efficiency, but it has the disadvantage of incomplete peeling, such as Publication No.: CN201336918Y (Green Walnut Peeling Machine).

[0008] Current mechanical peeling methods are simple to operate, fast, and reduce manual labor costs, but they also have problems such as incomplete removal of green husks, high walnut breakage rate, difficulty in collecting green husks, and waste of resources. Summary of the Invention

[0043] The structure of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that these embodiments are descriptive and not limiting.

[0044] Please see the following: A machine for peeling and washing green walnuts. Figures 1-15 The invention comprises a feeding device 1, a peeling device 2, a separation and cleaning device 3, and a collection and moving device 4. Please refer to [link / reference]. Figure 1 The specific structure and connection relationships of each part are as follows:

[0045] Feeding device

[0046] like Figures 2-4The system includes a feed hopper 1.1, an inner housing 1.2, an outer housing 1.3, and a drive motor 1.4. The feed hopper is a conical hopper that is wider at the top and narrower at the bottom. The outer housing is an annular shell with a flange 1.3.1 at its lower end. The inner housing is an annular shell with a conical surface on its upper end and a motor mounting hole at its lower center. Further, a ring of triangular ribs 1.5 is welded around the motor mounting hole at the lower end of the inner housing to reinforce it. The lower end of the feed hopper is coaxially inserted and fixed to the upper end of the outer housing. The inner housing is coaxially disposed within the outer housing. Multiple connecting ribs 1.7 are evenly distributed circumferentially between the lower edge of the inner housing and the lower inner ring of the outer housing, forming a fixed connection between the inner and outer housings at the lower part. A discharge port 1.6 is formed between the connecting ribs, and a discharge ring cavity 1.8, wider at the top and narrower at the bottom, is formed between the inner and outer housings, allowing materials to fall to the discharge port. The drive motor is inserted and fixed into the motor mounting hole at the lower end of the inner housing with its output shaft facing downwards.

[0047] Peeling device

[0048] like Figures 5-7 The peeling device is located below the feeding device and mainly includes an outer scraper assembly, an inner scraper assembly, an outer scraper mounting base 2.1, and an inner scraper mounting base assembly. The outer scraper mounting base is an annular fixed base. The outer scraper assembly consists of multiple vertically arranged outer scraper blades 2.3 evenly distributed and fixed along the circumference of the inner ring of the outer scraper mounting base. The inner scraper mounting base assembly is coaxially disposed inside the outer scraper mounting base. The inner scraper assembly consists of multiple vertically arranged inner scraper blades 2.4 evenly distributed along the circumference and movably connected radially to the outer ring of the inner scraper mounting base assembly. The specific structural form of the inner scraper mounting base assembly is as follows:

[0049] The device includes an inner turntable, an inner scraper seat 2.8, and a connecting spring 2.7. The inner turntable is composed of a central bushing 2.5, radial connecting rods 2.6, an inner ring 2.10, an outer ring 2.11, an upper cover plate 2.2, a lower cover plate, and a spring sleeve 2.9. The inner hole of the central bushing is a drive hole for external power input. The central bushing, inner ring, and outer ring are coaxially arranged. The central bushing is fixedly connected to the inner wall of the inner ring through radial connecting rods evenly distributed along the circumference. The inner ring and outer ring are fixedly connected through the upper and lower cover plates. Multiple radial inserts 2.13 are evenly distributed in a square pattern along the circumference of the outer wall of the inner ring, forming the inner end fixing posts of the connecting spring. A spring sleeve arranged radially is fixed on the outer wall of the inner ring outside each radial insert with a set gap. Multiple inner scraper seats are evenly distributed circumferentially outside the outer ring. Multiple inner scraper blades are evenly distributed on the outer wall of each inner scraper seat, arranged circumferentially. A radial insertion post 2.12 is vertically fixed on the inner wall of each inner scraper seat, forming the outer end fixing post of the connecting spring. The multiple inner scraper seats correspond one-to-one with the multiple inner spring fixing posts on the inner ring, and an adjustable radial connection is formed by connecting springs connected to the inner and outer end fixing posts. The spring sleeve is fitted onto the outside of the corresponding connecting spring with a clearance fit, providing directional protection for the spring.

[0050] The blades of the outer scraper assembly are arranged in the same direction, and the blades of the inner scraper assembly are also arranged in the same direction, but opposite to the blades of the outer scraper assembly. The inner scraper assembly and the outer scraper assembly form an annular peeling cavity. The annular peeling cavity is located directly below the material inlet of the above-mentioned feeding device, and the lower end of the peeling annular cavity is the material outlet.

[0051] When this peeling device is in operation, the green walnuts roll into the annular peeling chamber between the outer and inner scrapers. The inner scraper mounting bracket drives the inner scraper to make a circular motion. The blades of the inner and outer scrapers are in opposite directions, thus peeling the green walnut skin. The inner scraper is subjected to centrifugal force, which squeezes the rolling green walnuts. The connecting spring can reduce the centrifugal force to a certain extent, ensuring that the walnuts will not be damaged due to excessive squeezing.

[0052] Separation and cleaning device

[0053] Please see Figures 8-11 The separation and cleaning device is located below the peeling device and is used to separate the peeled green husk from the walnut and to clean the separated walnut.

[0054] The separation and cleaning device mainly includes a bowl-shaped dispensing cylinder 3.2, an outer cleaning cylinder 3.3, a drive shaft 3.1, an inner cleaning assembly 3.4, and a water supply device.

[0055] The bowl-shaped distributing cylinder consists of an outer grid ring 3.2.1 and an inner ring 3.2.2. The outer grid ring is formed by a ring of grid strips evenly distributed along the circumference, connected at the upper end by an end plate, forming a peeling gap 3.2.1a between the grid strips. The lower end of the outer grid ring is fixedly connected to the upper exterior of the outer washing cylinder by welding or other methods. The upper end of the inner ring is coaxially fixedly connected to the upper end of the outer grid ring by multiple (four in the attached figure) connecting ribs 3.2.3 evenly distributed along the circumferential axis. A material leakage annular cavity is formed between the outer ring and the outer grid ring, and this material leakage annular cavity is aligned vertically with the discharge port at the lower end of the aforementioned peeling annular cavity. A certain gap is left between the lower end of the outer ring and the upper end of the outer washing cylinder, the size of which allows the walnuts to fall smoothly into the outer washing cylinder below. The inner ring can be a solid ring structure as a whole. To save weight, the inner ring can adopt a weight-reducing structure with grid strips at the top and bottom as shown in the attached figure.

[0056] Multiple fixed brushes with bristles facing inward are evenly distributed and fixedly installed on the inner wall of the outer cleaning drum along the circumferential direction.

[0057] The inner cleaning assembly is coaxially arranged inside the outer cleaning cylinder and mainly includes a cylindrical inner rotor with bristles 3.4.1 evenly distributed on the outer surface of the inner rotor. The upper center of the inner rotor is driven to the lower part of the drive shaft, and the upper part of the drive shaft is threaded and driven to the center of the inner turntable. The upper end of the drive shaft is fixedly connected to the output shaft of the drive motor, realizing the simultaneous driving of the inner scraper and the inner cleaning assembly.

[0058] The water supply device includes a water tank 3.7 and a water supply pipe 3.8. Multiple water inlets 3.3.1 are evenly distributed along the circumference on the outer cleaning cylinder near the lower edge of the outer fence ring. The water tank contains a water pump, which is connected to the multiple water inlets through the water supply pipe to deliver water to the outer cleaning cylinder.

[0059] Using this separation and cleaning device, the peeled walnuts and green husk residue are discharged through the outlet of the peeling device and fall into the annular cavity between the outer and inner rings. During the falling process, the green husk residue is discharged downwards through the gaps between the grid bars on the outer ring, while the walnuts, blocked by the inner ring, slide down the inner wall of the outer ring and enter the outer cleaning cylinder. With the rotation of the inner cleaning component, the bristles on the inner cleaning component cooperate with the fixed brushes on the inner wall of the outer cleaning cylinder, and water rinsing completes the cleaning of the remaining green husks on the walnuts. To achieve a better cleaning effect, a discharge baffle 3.5 is installed on the inner wall of the outer cleaning cylinder between adjacent fixed brushes. The discharge baffle is distributed in a stepped pattern from top to bottom, ensuring that the walnuts can fully contact the brushes on the inner cleaning component during rotation, ensuring a cleaner and more thorough cleaning.

[0060] Collect mobile devices

[0061] Please see Figures 12-15 It is located below the separation and cleaning device to support the separation and cleaning device, so as to realize the collection of green husks and the output of cleaned walnuts.

[0062] The collection and moving device mainly includes a frame 4.2, a waste feeding bin 4.1, a blower 4.4, a waste collection box 4.6, a discharge plate 4.3, and a wastewater collection box 4.7.

[0063] The frame is a structure with an upper support platform and a lower support platform, and a caster wheel 4.5 is installed at each of the four corners of the lower end of the frame for easy movement. An opening is provided in the middle of the upper platform of the frame along its longitudinal direction. Two partitions are arranged along the long side of the opening between the upper and lower support platforms, dividing the area corresponding to the opening between the upper and lower support platforms into a left waste discharge area, a right waste discharge area, and a middle installation area. The waste feed hopper is vertically fixed to the upper end of the upper support platform and located outside the opening. The separation and cleaning device is integrally inserted into the middle of the waste feed hopper and the middle installation area. A cover plate 4.8 is installed above the middle installation area, outside the installation position of the separation and cleaning device, to prevent the peeled green slag from falling into this area. The upper part of the outer fence ring of the separation and cleaning device is fixedly connected to the inner wall of the waste feed hopper by multiple radial connectors.

[0064] The feeding plate is tilted and fixedly installed in the middle installation area, directly below the outer washing cylinder, to allow the washed walnuts to fall and be output through the feeding plate. The feeding plate can be fixed in the following way: a vertical upper insert plate is installed at the high end of the feeding plate, and a vertical slot that mates with the upper insert plate is installed at the lower end of the upper support platform. Simultaneously, a vertical lower insert plate is installed at the low end of the lower support, and a vertical slot that mates with the lower insert plate is installed at the upper end of the lower support platform. The tilted fixing of the feeding plate is achieved through the cooperation of these two sets of slots and insert plates.

[0065] A drainage hole is provided on the feeding plate. The wastewater collection box is placed directly below the feeding plate, with its upper surface slope consistent with that of the feeding plate, to collect the wastewater and waste residue after cleaning.

[0066] There are two waste collection boxes, one located in the left waste discharge area and the other in the right waste discharge area. A handle is provided on the outer side of each waste collection box for easy emptying of the inner husk. Two sets of blowers are located at the front and rear of the waste inlet hopper. Each set of blowers includes a blower 4.4.1, an air supply pipe 4.4.2, and a blower cover 4.4.3. The blower is fixedly installed on the upper support platform. An opening is provided on each of the front and rear side walls of the waste inlet hopper. The blower covers of the two sets of blowers are fixedly installed on the outer side of each opening. The two blowers are connected to the blower covers via their respective air supply pipes. Multiple air outlets 4.4.4 are provided on the air supply pipes inside the blower covers to deliver air into the front and rear sections of the waste inlet hopper.

[0067] A collection and movement device is used. During operation, the green shavings enter the waste feed hopper along the outer grid of the distribution cylinder. Part of it falls directly into the waste collection box through an opening at the top of the frame; the other part falls onto the inclined edge and rolls into the waste collection box. The blower outlet is located above the inclined surface on the inner wall of the waste feed hopper, blowing any remaining green shavings into the opening and into the waste collection box. Water tanks are installed at the lower end of the support platform on the frame, one at the front and one at the back. The inlets introduce external water flow, which is supplied to the cleaning device via a water supply pipe.

[0068] The lower end of the outer casing of the above-mentioned feeding device is fixedly supported on the upper end of the outer scraper mounting seat of the peeling device. The lower end of the inner scraper mounting seat assembly of the peeling device is rotatably supported and engaged with the upper end of the bowl-shaped distributing cylinder of the separation and cleaning device. An end face bearing (not shown in the attached figure) can be set on the mating surface of the two. The axis limit of the inner cleaning component is indirectly achieved by limiting the axis of the transmission shaft and the output shaft of the drive motor and limiting the axis of the transmission shaft and the inner scraper mounting seat assembly.

[0069] Working principle of this green walnut peeling and washing machine:

[0070] Before using this device, if time permits, place the harvested walnuts in a cool place for 3 to 5 days to allow the moisture on their outer skin to evaporate to a certain extent, which will make it easier for the machine to complete the peeling and cleaning work.

[0071] When the equipment is in operation, green walnuts are fed in through the top inlet. Under the action of the conical inner box, the green walnuts roll down their surface into the peeling device. The drive motor drives the transmission shaft to rotate at high speed. The transmission shaft is connected to a bushing, which drives the inner scraper to rotate through the inner turntable. With the cooperation of the inner and outer scrapers, the green skin is peeled off.

[0072] As the green husk peels off, the diameter of the walnut gradually decreases, eventually rolling down the inner wall of the outer grid ring of the feeding cylinder into the washing device. The green husk falls through the gaps in the outer grid ring into the waste feed hopper and then enters the waste collection box through the opening on the support platform on the frame. The inner wall of the waste feed hopper is sloped, with a blower inlet above the slope. When some green husks fall on the slope and cannot roll down, the blower can blow them into the waste collection box. The inner washing component in the washing device rotates under the drive of the transmission shaft. The walnuts rolling in are fully contacted with the brushes on the inner washing drum by the feeding baffle, and together with the fixed brushes on the inner wall of the outer washing cylinder and the water spray nozzles, the walnut skin is cleaned.

[0073] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
