Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a multifunctional fruit shelling machine. Background Technology

[0002] The fruit has a shell on the outside and contains seeds inside. Cypress seeds are a type of fruit; the kernels of the Chinese arborvitae (Platycladus orientalis) have calming, metabolism-boosting, relaxation-inducing, and fatigue-relieving effects. They can also be used as an adjunct treatment for insomnia, palpitations, anxiety, and fright, possessing high medicinal value. Cypress trees are native to northwestern China and widely distributed throughout Asia, generally growing at altitudes of 100 to 3440 meters, often along roadsides, on sunny slopes, and in mixed forests. Every autumn, people harvest the mature, unopened green cones (cypress fruits), remove the shells, and dry them to obtain the cypress seeds.

[0003] Many fruit trees, especially cypress trees, grow mostly in mountainous areas, so people have to harvest the heavy cypress fruits, skin and seeds together, and then dry and process them. Because cypress fruits, skin and seeds together, are heavy and large, transportation is inconvenient, labor-intensive, and time-consuming; moreover, the cypress seeds need to undergo further drying. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a multifunctional fruit shelling machine that can be easily carried to mountainous areas where fruit trees grow.

[0017] 1. This invention integrates an eccentric crushing and screening device, a spiral screening and conveying device, a drying device, and a collection device into a single unit. It is compact, lightweight, and easily portable for use in mountainous areas where fruit trees thrive. The eccentric crushing and screening device crushes and screens the fruit. The dehulled seeds are then conveyed to the drying device via the spiral screening and conveying device, where they are dried before being transferred to the collection device.

[0018] 2. This invention features a rectangular case with a lid fixed to the front side and shoulder straps on the rear side. The lid facilitates disassembly and maintenance. The backpack-style design offers ample capacity, convenient travel, and excellent portability. It is ergonomically designed to reduce pressure on the shoulders and back during extended periods of carrying.

[0019] 3. This invention uses the eccentric crushing and screening device to perform primary screening of fruit shells, and then uses the swinging arc-shaped screen plate of the spiral screening and conveying device to perform secondary screening. The separation efficiency of fruit shells and seeds is high and the screening effect is good.

[0020] 4. This invention includes a reciprocating oscillating device, which drives the guide plate to oscillate back and forth. This ensures that the seeds are heated evenly during the drying process, which not only improves drying efficiency but also reduces drying time.

[0021] 5. The present invention is equipped with a cleaning device, wherein the roller brush rotates in the opposite direction to the sieve barrel. The roller brush can remove the debris adhering to the outer surface of the sieve barrel, thereby preventing fruit debris from clogging the sieve holes.

[0022] 6. The collection device of this invention has a drawer-type structure, and the hopper can be pulled out directly for easy access.

[0023] 7. The motor of the present invention is a dual-output shaft motor. One output shaft is connected to the transmission device, which drives the eccentric rolling and screening device and the spiral screening and conveying device to operate through the transmission device. The other output shaft is connected to the reciprocating swing device, which drives the reciprocating swing device to operate. The structure is compact, reducing its own weight and volume.

[0024] 8. The left end face of the eccentric roller of the present invention is located on the right side of the left end face of the sieve barrel. A gap is left at the left end face of the eccentric roller, which provides a buffer time for the fruit to enter the eccentric roller crushing and screening device and solves the problem of fruit blockage.

[0043] like Figure 1 , Figure 2 As shown, this embodiment is a multifunctional cypress fruit shelling machine, including a machine box 1, a left-side transmission device 2, a reciprocating swing device 3, a motor 4, a cleaning device 5, a right-side transmission device 6, an eccentric crushing and screening device 7, a spiral screening and conveying device 8, a drying device 9, and a collecting device 10.

[0044] like Figure 3As shown, the chassis 1 includes a chassis 101, shoulder straps 102, a U-shaped plate 104, a cover 105, a guide plate 106, and a partition plate 107. The chassis 101 is rectangular. The cover 105 is fixed to the front side of the chassis with screws, and the two shoulder straps 102 are fixed to the rear side of the chassis. The guide plate 106 is arc-shaped and fixed inside the chassis, with its bottom end fixed to the upper left side of the collecting device 10. The U-shaped plate 104 is fixed inside the chassis 1 and located above the guide plate 106. The partition plate 107 is vertically fixed inside the chassis 101, separating the left-side transmission device 2. A feed inlet 108 is provided on the left side of the top surface of the chassis, and a waste discharge outlet 103 is provided at the U-shaped plate 104 on the right side of the chassis.

[0045] like Figure 4 As shown, the eccentric rolling and screening device 7 includes a screen barrel 701, an eccentric rolling roller 702, a gear and rack eccentric structure 703, a screen barrel support 704, a bushing 705, a left rotating shaft 706, a positioning disc 707, a support 709, and a right rotating shaft 711. Screen holes 708 are evenly distributed on the wall of the screen barrel 701, and the surface roughness of the lower inner wall of the screen barrel is greater than 12.5. A shaft hole 710 is provided at the center of the support 709. The axis of the eccentric rolling roller is located above the axis of the screen barrel, and the left end face of the eccentric rolling roller is located to the right of the left end face of the screen barrel. A gap is provided between the outer wall of the eccentric rolling roller and the inner wall of the screen barrel.

[0046] The bushing 705 is fixed to the center of the screen barrel support 704. The left inner wall of the screen barrel 701 is fixed to both ends of the screen barrel support 704. The screen barrel support 704 is located inside the screen barrel 701, and the left end face of the screen barrel support 704 is on the same plane as the left end face of the screen barrel 701. The support 709 is fixed to the right end face of the screen barrel 701. The support 709 is located outside the screen barrel 701. The support 709 has a shaft hole 710 at its center, through which the right-hand rotating shaft 711 passes.

[0047] Two positioning discs 707 are provided, located on the left and right sides of the eccentric rolling roller 702. A left rotating shaft 706 is fixed to the left end face of the left positioning disc 707, and a right rotating shaft 711 is fixed to the right end face of the right positioning disc 707. A bushing 705 is mounted on the left rotating shaft 706 and rotatably connected to it. The right rotating shaft 711 passes through a shaft hole 710, and a bracket 709 is mounted on the right rotating shaft 711 and rotatably connected to it.

[0048] The positioning disc 707 has elongated bolt holes. The left and right end faces of the eccentric rolling roller 702 are connected to the positioning disc 707 by bolts. The gear of the gear and rack eccentric structure 703 is mounted on the roller shaft of the eccentric rolling roller 702, and the rack of the gear and rack eccentric structure 703 is fixed to the positioning disc 707. The distance between the outer wall of the eccentric rolling roller 702 and the screen barrel 701 is adjusted by the gear and rack eccentric structure 703 and the elongated bolt holes, thus adjusting the eccentricity of the eccentric rolling roller 702. The axis of the eccentric rolling roller is located above the axis of the screen barrel, and the distance between the axis of the eccentric rolling roller and the axis of the screen barrel is the eccentricity of the eccentric rolling roller 702.

[0049] The left end of the eccentric crushing roller 702 is conical. The screen barrel support 704 is located inside the screen barrel 701, and the width of the screen barrel support 704 is the distance between the left end of the eccentric crushing roller 702 and the left end face of the screen barrel 701. The design of the distance on the left side of the eccentric crushing roller 702 in this embodiment provides a buffer time for the cypress fruit to enter the eccentric crushing and screening device 7, solving the problem of cypress fruit accumulation and blockage. The left end of the eccentric crushing and screening device 7 is connected to the feed inlet 108. The cypress fruit enters between the outer wall of the eccentric crushing roller 702 and the inner wall of the screen barrel 701. Through the compression of the eccentric crushing roller 702 against the barrel wall and the screen holes 708, this invention has the function of crushing fruit and discharging debris, greatly saving internal space.

[0050] In this embodiment, the sieve holes 708 are arranged along the axial direction of the sieve barrel 701, and the inner surface of the sieve barrel 701 opposite to the sieve holes 708 is a rough inner surface with a large roughness. The diameter of the sieve holes 708 is 3mm, and the roughness of the rough inner surface can be Ra25 to Ra12.5. The sieve holes 708 can effectively separate cypress seeds, while the large roughness enhances the crushing effect, prevents insufficient crushing due to slippage, and improves the shelling efficiency.

[0051] In this embodiment, the eccentricity of the eccentric roller 702 is 4mm. The closest distance between the outer surface of the eccentric roller 702 and the inner surface of the screen barrel 701 is 2.6mm, and the furthest distance is 10.6mm. The closest distance between the outer radius of the spiral structure on the surface of the eccentric roller 702 and the inner surface of the screen barrel 701 is 1mm. The outer surface of the eccentric roller 702 is provided with spiral strips 712, which are spiral strips 712 along the axial direction of the eccentric roller 702. The spacing of the spiral strips 712 corresponds to the diameter of the cypress fruit, increasing friction while promoting fruit movement and preventing material blockage. During installation, the distal end of the eccentric roller 702 faces the rough inner surface of the screen barrel 701, and the proximal end of the eccentric roller 702 faces the screen hole 708.

[0052] like Figure 1 , Figure 5 , Figure 6As shown, the cleaning device 5 is installed directly above the eccentric crushing and screening device 7. The cleaning device 5 includes a drive shaft 501 and brushes 502 evenly distributed on the drive shaft 501, thus forming a roller brush. The roller brush rotates in the opposite direction to the eccentric crushing roller 702. The roller brush is used to remove debris adhering to the outer surface of the screen barrel 701. The right-side transmission device 6 includes a drive pulley 603, a driven pulley 601, and a V-belt 602. The drive pulley 603 is installed on the right rotating shaft 711, and the driven pulley 601 is installed on the drive shaft 501. The drive pulley 603 drives the driven pulley 601 to rotate through the V-belt 602, which in turn drives the drive shaft 501 to rotate. The brushes 502 on the drive shaft 501 remove fruit shell debris adhering to the surface of the screen barrel, completing the cleaning work and effectively solving the problem of fruit debris clogging the screen holes.

[0053] like Figure 7 As shown, the spiral screening and conveying device 8 is installed directly below the eccentric crushing and screening device 7, and includes a spiral shaft 801, spiral blades 804, an arc-shaped screen plate 803, and a swing rod 802. The spiral shaft 801 is a crankshaft with connecting rod journals at both ends. The spiral blades 804 are fixed to the middle of the spiral shaft. The swing rod 802 has an elongated hole in the middle, through which the connecting rod journals pass. The swing rod 802 is mounted on the spiral shaft 801. The rotation of the spiral shaft 801 drives the swing rod 802 to swing, which in turn drives the arc-shaped screen plate 803 to swing back and forth. The arc-shaped screen plate 803 has evenly distributed screen holes. The arc-shaped screen plate 803 further screens the crushed fruit product and fruit fragments. The semi-finished fruit is conveyed to the drying device 9 through the spiral drive device 804. The U-shaped plate 104 inside the box 101 is located directly below the arc-shaped sieve plate 803 with the arc curvature facing downwards. Excess fruit fragments will be sieved out by the arc-shaped sieve plate 803 and then discharged by the U-shaped plate 104.

[0054] like Figure 8 As shown, the drying device 9 includes a hinge block 901, a heating plate 902, a drive rod 903, and a guide plate 904. The right end of the guide plate 904 is hinged to the housing 101 via the hinge block 901 and a hinge shaft. The left end of the guide plate 904 is connected to the right end of the drive rod 903, and the left end of the drive rod 903 is connected to a reciprocating swing device 3, which drives the guide plate 904 to swing back and forth. The right end of the guide plate 904 is higher than the left end. The guide plate 904 is wavy, and its upper surface is provided with parallel and equally spaced guide strips. The heating plate 902 is installed below the guide plate 904.

[0055] The semi-finished fruit is conveyed to the drying device 9 via the spiral screening conveyor 8. The guide plate 904 forces the fruit seeds to move along a curved track under the action of gravity. The heating plate 902 below the guide plate 904 dries the fruit. The reciprocating oscillating device 3 drives the guide plate 904 to swing back and forth, ensuring that the cypress seeds are heated evenly during the drying process, which not only improves the drying efficiency but also reduces the drying time. The cypress seeds move from the right side of the guide plate 904 to the left side. At this time, the seeds are dry. The guide plate 106 on the left side of the machine box 1 guides the seeds so that they fall into the collection device 10.

[0056] like Figure 9 As shown, the reciprocating swing device 3 includes an adjusting block 301, a swing rod 302, a turntable 303, a support base 304, and a groove 305. The support base 304 has two parallel support blocks with through holes. The swing rod 302 passes through these through holes and is mounted on the support base 304, allowing it to move back and forth. The turntable 303 is mounted on the output shaft on the right side of the motor 4. The adjusting block 301 is mounted on the turntable 303 and is a slider that slides along a track. The groove 305 has an elongated hole through which the adjusting block 301 passes.

[0057] Motor 4 drives turntable 303 to rotate, which in turn drives adjusting block 301 to move along the slide rail, thereby driving swing arm 302 to move back and forth. The left end of drive rod 903 is connected to swing arm 302, thus realizing the back and forth swing of guide plate 904. Adjusting block 301 controls the movement amplitude of tank 305 and swing arm 302, and support base 304 plays a supporting and stabilizing role.

[0058] like Figure 10 As shown, the collection device has a drawer-type structure, including a pull-out hopper 1001, which is installed below the drying device 9. A pull groove 1002 is provided in the middle of the front side of the hopper 1001 for easy pulling out.

[0059] like Figure 11 As shown, the left-side transmission device 2 includes a drive gear 201, an idler gear 202, a driven gear 203, a left drive pulley 204, and a left driven pulley 205. The drive gear 201 is mounted on the left output shaft of the motor 4. The idler gear 202 and the left drive pulley 204 are mounted on the left end of the helical shaft 801. The driven gear 203 and the left driven pulley 205 are mounted on the left end of the left rotating shaft 706. The drive gear 201, idler gear 202, and driven gear 203 mesh sequentially, and the left drive pulley 204 and the left driven pulley 205 are connected by a belt. The left-side transmission device 2 is equipped with both gear transmission and belt transmission. The pulleys and gears can be used alternately, effectively preventing motor burnout due to blockage.

[0060] Motor 4 is electrically connected to the battery, which supplies power to motor 4. The battery is also electrically connected to the heating plate 902, which supplies power to heating plate 902.

[0061] The working principle and process of this invention are as follows:

[0062] Cypress trees bloom from March to May each year, and their fruits ripen from May to June. The best time to harvest the fruits is from August to October, when they are about to split open but have not yet fallen off.

[0063] After the harvested cypress fruits are conveyed into the cypress dehulling machine through the feed inlet 108, the eccentric crushing and screening device 7, driven by the motor 4, rotates the screen barrel 701 and the eccentric crushing roller 702 relative to each other. When the distal end of the eccentric crushing roller 702 rotates to the bottom, the lower part of the screen barrel 701 (i.e., the part without screen holes 708 and with a rough inner surface) is opposite to the distal end of the eccentric crushing roller 702. Under the action of gravity, the cypress fruits will slide down to the bottom to complete the crushing work, and most of the cypress fruit shells will be discharged from the waste discharge outlet 103.

[0064] When the proximal end of the eccentric roller 702 rotates downwards, the upper part of the sieve barrel 701 (i.e., the position with sieve holes 708) is opposite to the proximal end of the eccentric roller 702. Under the action of gravity, the crushed debris and cypress seeds will slide down and fall into the spiral screening and conveying device 8 through the sieve holes 708. The spiral screening and conveying device 8 conveys the cypress seeds from left to right to the drying device 9. Excess fruit debris will be screened out by the sieve plate 803 and then discharged through the U-shaped plate 104 inside the machine housing 1.

[0065] The drying device 9 is tilted, and the guide plate 904 allows the fruit seeds to move along a curved track under the action of gravity. Below the guide plate 904 is the heating plate 902 to dry the fruit. The motor 4 is connected to the wheel 303 on the right side. The wheel 303 is equipped with an adjustable block 301 and a trough 305. The adjustable block 301 can adjust the movement range of the trough 305. The wheel support 304 stabilizes the movement direction of the trough 305, and the drive rod 903 drives the drying device 9 to work.

[0066] The seeds move from the right side of the drying device 9 to the left side of the guide plate 904. At this point, the seeds are dry. The guide plate 106 on the left side of the box 101 guides the seeds, causing them to fall into the hopper 1001. The debris is discharged from the machine through the discharge port 103, thus completing the entire process of shelling the cypress fruit. The shelling rate of this invention can reach 80%.

[0067] This invention integrates an eccentric crushing and screening device 7, a spiral screening and conveying device 8, a drying device 9, and a collecting device 10 into a single housing 1. This design is compact, lightweight, and easily portable for use in mountainous areas where cypress trees thrive. The eccentric crushing and screening device 7 crushes and screens the cypress fruits. The dehulled cypress seeds are then conveyed to the drying device 9 via the spiral screening and conveying device 8. The drying device 9 dries the cypress seeds and then transfers them to the collecting device 10. This invention repeatedly crushes and screens the cypress fruits using the eccentric crushing and screening device 7, separating debris from the seeds. This effectively prevents the fruits from remaining unhulled, resulting in higher dehulling efficiency and better results. The cypress fruits can be dehulled and dried on-site immediately after harvesting, and the seeds can be stored in the collecting device 10, saving time and effort and optimizing the process.

[0068] This invention features a rectangular case with a lid 105 fixed to the front side of the case and a shoulder strap 102 on the rear side. The lid 105 facilitates disassembly and maintenance. The backpack-style design offers large capacity, convenient travel, and excellent portability. It is ergonomic and reduces pressure on the shoulders and back during prolonged carrying.

[0069] This invention uses the eccentric crushing and screening device 7's sieve barrel 701 to perform primary screening of cypress fruit shells, and the spiral screening and conveying device 8's swinging arc-shaped sieve plate 803 to perform secondary screening. The separation efficiency of fruit shells and seeds is high and the screening effect is good.

[0070] This invention includes a reciprocating oscillating device 3, which drives the guide plate 904 to oscillate back and forth. This ensures that the cypress seeds are heated evenly during the drying process, which not only improves drying efficiency but also reduces drying time.

[0071] The present invention is equipped with a cleaning device 5, whose roller brush rotates in the opposite direction to the eccentric rolling roller 702. The roller brush can remove the debris adhering to the outer surface of the sieve barrel and prevent fruit debris from clogging the sieve holes.

[0072] The collection device 10 of the present invention has a drawer-type structure, and the hopper 1001 can be pulled out directly for easy access.

[0073] The motor 4 of this invention is a dual-output shaft motor. One output shaft is connected to the transmission device, which drives the eccentric rolling and screening device 7 and the spiral screening and conveying device 8 to operate. The other output shaft is connected to the reciprocating swing device 3, which drives the reciprocating swing device 3 to operate. The structure is compact, reducing its own weight and volume.

[0074] The left end face of the eccentric roller of the present invention is located to the right of the left end face of the screen barrel. A gap is left at the left end face of the eccentric roller to provide a buffer time for the cypress fruit to enter the eccentric roller screening device 7, thus solving the problem of cypress fruit blockage.

[0075] The scope of protection of this invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be included within the scope of protection of this invention.
