Description

Technical Field

[0001] This invention relates to the field of shell-breaking machine technology, and more specifically to a horizontal disc rotating extrusion shell-breaking machine. Background Technology

[0002] Walnut shelling is the most crucial step in walnut processing, a vital link in enhancing the economic value and industrial development of walnuts. However, due to the hard, difficult-to-crack shells of walnuts and the easily broken kernels that are difficult to extract intact, existing shelling machines often suffer from insufficient crushing, low kernel yield, and large shell fragments, hindering their widespread use. To reduce losses and ensure kernel quality, walnut shelling currently relies heavily on manual labor. However, manual shelling suffers from low efficiency, high labor intensity, high costs, high contamination levels, and hygiene issues, severely impacting kernel quality. The development of walnut shelling and kernel extraction equipment has become a bottleneck restricting the development of the walnut processing industry.

[0003] Existing walnut shelling machines mainly use the extrusion method to crack the shell and extract the kernel, applying a concentrated normal force to break the shell while ensuring the integrity of the kernel. However, in actual production, the following problems exist: 1) Poor production continuity, affecting work efficiency; 2) Fixed extrusion spacing, unable to adapt to walnuts of different diameters; 3) Low shelling efficiency. For example, patent number ZL202010502049.2, entitled "A Walnut Shelling Machine," uses a striking device and an adjustment device to crack the walnuts, achieving single-kernel extraction and striking shelling, but the striking force and distance cannot be adjusted, making it difficult to apply to walnuts of different diameters; another example is patent number ZL202223502447.8, entitled "A Walnut Shelling Equipment," which uses double clamping rollers and collision shelling to achieve extrusion and collision shelling, but the gap between the double clamping rollers cannot be adjusted, resulting in low shelling efficiency.

[0004] Therefore, providing a horizontal disc rotating extrusion crusher with adjustable extrusion gap is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a horizontal disc rotating extrusion shell-breaking machine that operates continuously and can adjust the extrusion gap according to different walnut sizes, thereby improving work efficiency and shell-breaking effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A horizontal disc rotating extrusion shell-breaking machine includes a frame, a feed hopper, a shell-breaking device, a discharge hopper, a power unit, and a lifting and conveying device. The feed hopper, the shell-breaking device, and the discharge hopper are installed sequentially on the frame from top to bottom, with the feed hopper corresponding to the feed inlet of the shell-breaking device and the discharge hopper corresponding to the discharge outlet of the shell-breaking device. The power unit is installed on the frame and is drivenly connected to the shell-breaking device. The lifting and conveying device is located on one side of the frame, and its output port corresponds to the position of the feed hopper.

[0008] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0009] The lifting conveyor continuously transports walnuts to the feed hopper, from where they enter the shell-breaking device. Once the shells are broken, the walnuts are output through the discharge hopper, enabling continuous walnut shell-breaking processing and improving work efficiency.

[0010] Furthermore, the shell-breaking device includes a housing, a mounting ring, a boss, a working disc assembly, and a flexible plate. The housing is mounted on the frame. The mounting ring and the boss are sequentially installed inside the housing from the outside to the inside and are coaxially distributed to form a shell-breaking space between the mounting ring and the boss. The working disc assembly is installed inside the housing and is located below the mounting ring and the boss, coaxially distributed. The power unit is connected to the working disc assembly. The flexible plate is inserted into the slot of the mounting ring and located within the shell-breaking space.

[0011] Furthermore, the working disc assembly includes a working disc, multiple inner ring movable push rods, multiple outer ring movable push rods, a rotating shaft, a rotating wheel, and multiple rotating wheel protrusions. The working disc is driven by the power device. The working disc has multiple working holes evenly arranged circumferentially. The multiple inner ring movable push rods are respectively installed on the inner side of the working disc and are evenly arranged circumferentially. The multiple outer ring movable push rods are respectively installed on the outer side of the working disc and correspond to the positions of the multiple inner ring movable push rods. Each inner ring movable push rod is tangent to the protrusion, and each outer ring movable push rod is tangent to the housing. The clamping arms of the inner ring movable push rod and its corresponding outer ring movable push rod are aligned with the lower part of the working hole. The rotating shaft is fixed to the inner side of the mounting ring. The rotating wheel is rotatably connected to the rotating shaft. The multiple rotating wheel protrusions are respectively fixed on the circumferential wall of the rotating wheel and are evenly distributed circumferentially, and at least one rotating wheel protrusion is inserted into the working hole.

[0012] Furthermore, the boss includes a boss body, an inner ring, multiple inner ring protrusions, an inner movable block, an inner hinge, and a ratchet adjusting handle. The boss body is mounted on the mounting ring via a baffle on its conical surface. The inner ring is fixed to the bottom of the boss body. The multiple inner ring protrusions are respectively fixed to the outer side wall of the inner ring. The inner movable block is hinged to the inner ring via the inner hinge. The ratchet adjusting handle is threadedly connected to the inner ring, and the extended end of the ratchet adjusting handle contacts the inner movable block. The multiple inner ring movable push rods are tangent to the inner ring and the inner movable block, respectively.

[0013] Furthermore, the housing includes a housing body, multiple outer ring protrusions, an outer movable block, an outer hinge, and an outer adjusting handle. The housing body is mounted on the frame. The multiple outer ring protrusions are respectively fixed to the inner sidewall of the housing body. The outer movable block is hinged to the housing body via the outer hinge, and the outer movable block corresponds to the position of the inner movable block. The outer adjusting handle is threaded to the housing body, and the extended end of the outer adjusting handle contacts the outer movable block. The multiple outer ring movable push rods are tangent to the inner wall of the housing body and the outer movable block, respectively.

[0014] The beneficial effects of adopting the above-mentioned further technical solution are that the ratchet adjustment handle can adjust the position of the inner movable block, and then when the working disc assembly rotates to the position of the inner movable block, the radial position of the inner ring movable push rod is adjusted. At the same time, the outer adjustment handle can adjust the position of the outer movable block, and then when the working disc assembly rotates to the position of the outer movable block, the radial position of the outer ring movable push rod is adjusted, thereby realizing the adjustment of the clamping size of the corresponding two clamping arms and realizing the adjustment of the extrusion gap according to different walnut sizes.

[0015] Furthermore, the inner ring has five protrusions with an angle range of 47°, arranged clockwise as a first inner protrusion, a second inner protrusion, a third inner protrusion, a fourth inner protrusion, and a fifth inner protrusion, with equal intervals between the second, third, fourth, and fifth inner protrusions; the outer ring has six protrusions with an angle range of 60°, arranged clockwise as a first outer protrusion, a second outer protrusion, a third outer protrusion, a fourth outer protrusion, a fifth outer protrusion, and a sixth outer protrusion. The first outer protrusion, the second outer protrusion, the third outer protrusion, the fourth outer protrusion, and the fifth outer protrusion are spaced equally apart; the radial line of the first inner protrusion coincides with the radial line of the first outer protrusion, the radial line of the second inner protrusion coincides with the radial line of the second outer protrusion, the radial line of the third inner protrusion coincides with the radial line of the third outer protrusion, the radial line of the fourth inner protrusion coincides with the radial line of the fourth outer protrusion, and the radial line of the fifth inner protrusion coincides with the radial line of the fifth outer protrusion.

[0016] The beneficial effect of adopting the above-mentioned further technical solution is that the inner ring movable push rod generates intermittent vibration when passing the inner ring protrusion, and the outer ring movable push rod generates intermittent vibration when passing the outer ring protrusion. The vibration is eventually transmitted to the walnut, which adjusts the posture of the walnut in the working hole, so that the walnut is embedded in the working hole as a whole.

[0017] Furthermore, the bottom of the lifting and conveying device is equipped with multiple casters.

[0018] The beneficial effect of adopting the above-mentioned further technical solution is that the orientation of the lifting conveyor relative to the frame can be adjusted, thereby avoiding the problem of not being able to properly arrange the machine due to space limitations and improving applicability.

[0019] Furthermore, the shell-breaking device also includes a compression baffle and a movable cover plate. The compression baffle is inserted into the mounting ring and located directly above the working hole. The movable cover plate is placed in the mounting groove of the boss body and has a notch.

[0020] The beneficial effects of adopting the above-mentioned further technical solution are that the extrusion baffle restricts the vertical displacement of the walnut during extrusion, thereby increasing the success rate of walnut shell breaking; and the movable cover can be removed, making it convenient to adjust the internal structure of the boss body.

[0021] Furthermore, both the ratchet adjustment handle and the outer adjustment handle are provided with scale lines.

[0022] The beneficial effect of adopting the above-mentioned further technical solution is that it displays the size of the extrusion gap, making it easier to adjust the shell-breaking gap according to the size of the walnut.

[0023] Furthermore, the power unit includes an electric motor, a driving pulley, a gearbox, a driven pulley, and a belt. The electric motor is mounted on the frame; the driving pulley is mounted on the output shaft of the electric motor; the gearbox is mounted on the frame; the shaft hole at the center of the bottom of the working disc is mounted on the output shaft of the gearbox; the driven pulley is mounted on the input shaft of the gearbox; and the driving pulley and the driven pulley are connected by the belt drive.

[0024] The beneficial effect of adopting the above-mentioned further technical solutions is that a compact and efficient transmission is achieved. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1-12 As shown in the figure, this invention discloses a horizontal disc rotation extrusion shell-breaking machine, including a frame 1, a feed hopper 2, a shell-breaking device 3, a discharge hopper 4, a power unit 5, and a lifting and conveying device 6. The feed hopper 2, the shell-breaking device 3, and the discharge hopper 4 are installed on the frame 1 from top to bottom, with the feed hopper 2 corresponding to the feed inlet of the shell-breaking device 3 and the discharge hopper 4 corresponding to the discharge outlet of the shell-breaking device 3. In this embodiment, the feed hopper 2 is a sheet metal part, which is bolted to the top of the frame 1 via a side plate. The shell-breaking device 3 is fixed inside the frame 1 by bolts. The discharge hopper 4 is a sheet metal part, which is bolted to the right side of the frame 1. The power unit 5 is installed on the frame 1 and is connected to the shell-breaking device 3 for transmission. The lifting and conveying device 6 is located on one side of the frame 1, and its output port corresponds to the position of the feed hopper 2. The present invention uses a lifting conveyor device 6 to continuously transport walnuts to the feed hopper 2, and then from the feed hopper 2 into the shell-breaking device 3. After shell-breaking is completed, the walnuts are output through the discharge hopper 4, thus realizing the continuous processing of walnut shell-breaking and improving work efficiency.

[0040] To further optimize the technical solution of the present invention, the frame 1 is made of square tubes through processing and welding. The bottom of the frame 1 is equipped with horizontal adjustment feet. Multiple reinforcing plates are welded between the vertical square tubes and the horizontal square tubes of the frame 1 to improve the stability and adaptability of the machine structure.

[0041] Specifically, the shell-breaking device 3 includes a housing 31, a mounting ring 32, a boss 33, a working disc assembly 34, and a flexible plate 35. The housing 31 is mounted on the frame 1. The mounting ring 32 and the boss 33 are installed sequentially from the outside to the inside of the housing 31 and are coaxially distributed to form a shell-breaking space between the mounting ring 32 and the boss 33, confining the walnut within the shell-breaking space. The working disc assembly 34 is installed inside the housing 31 and is located coaxially below the mounting ring 32 and the boss 33. The mounting ring 32 restricts the up-and-down movement of the working disc assembly 34. The power device 5 is connected to the working disc assembly 34 via a transmission. The flexible plate 35 is inserted into the slot of the mounting ring 32 and is located within the shell-breaking space. In this embodiment, the flexible plate 35 is made of silicone and is arranged in a uniform circumferential array with an angle range of 90°. There are 3 of them, which are used to pry the walnut so that it can smoothly enter the working hole 3411.

[0042] Specifically, the working disc assembly 34 includes a working disc 341, multiple inner ring movable push rods 342, multiple outer ring movable push rods 343, a rotating shaft 344, a rotating wheel 345, and multiple rotating wheel protrusions 346. In this embodiment, there are 36 inner ring movable push rods 342 and 36 outer ring movable push rods 343. The working disc 341 is connected to the power device 5 for transmission. The working disc 341 has multiple working holes 3411 evenly arranged circumferentially. In this embodiment, there are 36 working holes 3411. The multiple inner ring movable push rods 342 are respectively installed on the inner side of the working disc 341 and are evenly arranged circumferentially. The multiple outer ring movable push rods 343 are respectively installed on the outer side of the working disc 341 and are corresponding to the positions of the multiple inner ring movable push rods 342. Each inner ring movable push rod 342 is tangent to the protrusion 33, and each outer ring movable push rod 343 is tangent to the shell. The inner ring movable push rod 342 and its corresponding outer ring movable push rod 343 are tangent to each other, and their clamping arms are aligned with the lower part of the working hole 3411. The rotating shaft 344 is fixed inside the mounting ring 32. In this embodiment, the rotating shaft 344 is provided with an external thread and is inserted into the threaded hole of the mounting ring 32. The rotating wheel 345 is rotatably connected to the rotating shaft 344. Multiple rotating protrusions 346 are respectively fixed on the circumferential wall of the rotating wheel 345 and are evenly distributed along the circumference. At least one rotating protrusion 346 is inserted into the working hole 3411. In this embodiment, there are 6 rotating protrusions 346. The rotating protrusions 346 work in cooperation with the working disc 341. When the working disc 341 rotates, it drives the rotating wheel 345 to rotate, always keeping at least one rotating protrusion 346 inserted into the working hole 3411 to push out the broken walnuts from the working hole 3411.

[0043] Specifically, the boss 33 includes a boss body 331, an inner ring 332, multiple inner ring protrusions 333, an inner movable block 334, an inner hinge 335, and a ratchet adjusting handle 336. The boss body 331 is mounted on the mounting ring 32 via a baffle 38 on its conical surface, thus fixing the boss body 331 at the center of the housing 31. The inner ring 332 is fixed to the bottom of the boss body 331; in this embodiment, the fixing method is welding. The multiple inner ring protrusions 333 are respectively fixed to the outer side wall of the inner ring 332; in this embodiment, the fixing method is welding. The inner movable block 334 is connected to the inner ring 332 via the inner hinge 335. The hinge, i.e., the inner hinge 335 is composed of two half-hinges hinged together. One half-hinge is fixed to the inner ring 332 by screws, and the inner movable block 334 is fixed to the other half-hinge by screws. The ratchet adjustment handle 336 is threadedly connected to the inner ring 332, and the extended end of the ratchet adjustment handle 336 contacts the inner movable block 334. The position of the inner movable block 334 can be adjusted by rotating the ratchet adjustment handle 336. In this embodiment, the ratchet adjustment handle 336 is provided with external threads and is inserted into the threaded hole of the inner ring 332. Multiple inner ring movable push rods 342 are tangent to the inner ring 332 and the inner movable block 334, respectively.

[0044] Specifically, the housing 31 includes a housing body 311, multiple outer ring protrusions 312, an outer movable block 313, an outer hinge 314, and an outer adjusting handle 315. The housing body 311 is mounted on the frame 1. The multiple outer ring protrusions 312 are respectively fixed to the inner sidewall of the housing body 311. In this embodiment, the fixing method is welding. The outer movable block 313 is hinged to the housing body 311 through the outer hinge 314, and the outer movable block 313 corresponds to the inner movable block 334 in position. The position of the outer movable block 313 can be adjusted by rotating the outer adjusting handle 315. In this embodiment, the outer hinge 314 is composed of two half-hinges hinged together. One half-hinge is fixed to the housing body 311 by screws, and the outer movable block 314 is fixed to the other half-hinge by screws. The outer adjusting handle 315 is threadedly connected to the housing body 311, and the extended end of the outer adjusting handle 315 contacts the outer movable block 313. In this embodiment, the outer adjusting handle 315 is provided with external threads and is inserted into the threaded hole of the housing body 311. Multiple outer ring movable push rods 343 are tangent to the inner wall of the housing body 311 and the outer movable block 313, respectively.

[0045] In the above scheme, the ratchet adjustment handle 336 can adjust the position of the inner movable block 334. Then, when the working disc assembly 34 rotates to the position of the inner movable block 334, the radial position of the inner ring movable push rod 342 is adjusted. At the same time, the outer adjustment handle 315 can adjust the position of the outer movable block 313. Then, when the working disc assembly 34 rotates to the position of the outer movable block 313, the radial position of the outer ring movable push rod 343 is adjusted, thereby realizing the adjustment of the clamping size of the two clamping arms and realizing the adjustment of the extrusion gap according to different walnut sizes.

[0046] Specifically, there are five inner ring protrusions 333, with an angle range of 47°, arranged clockwise as the first inner protrusion, second inner protrusion, third inner protrusion, fourth inner protrusion, and fifth inner protrusion, with equal intervals between them; there are six outer ring protrusions 312, with an angle range of 60°, arranged clockwise as the first outer protrusion, second outer protrusion, third outer protrusion, fourth outer protrusion, fifth outer protrusion, and sixth outer protrusion, with equal intervals between them; the radial lines of the first inner protrusion coincide with the radial lines of the first outer protrusion, while the radial lines of the second inner protrusion, third inner protrusion, fourth outer protrusion, and fifth inner and fifth outer protrusions are staggered. In this way, the inner ring movable push rod 342 generates intermittent vibrations when passing the inner ring protrusion 333, and the outer ring movable push rod 343 generates intermittent vibrations when passing the outer ring protrusion 312. These vibrations are ultimately transmitted to the walnut, adjusting the walnut's posture within the working hole 3411, so that the walnut is fully embedded in the working hole 3411. Of course, the arrangement of the inner ring protrusion 333 and the outer ring protrusion 312 is not unique and can be tailored to different design requirements.

[0047] To further optimize the technical solution of the present invention, multiple casters are installed at the bottom of the lifting conveyor 6, which can adjust the position of the lifting conveyor 6 relative to the frame 1, thereby avoiding the problem of not being able to arrange the machine normally due to space limitations and improving applicability.

[0048] To further optimize the technical solution of the present invention, the shell-breaking device 3 also includes a squeezing baffle 36 and a movable cover plate 37. The squeezing baffle 36 is inserted into the mounting ring 32 and located directly above the working hole 3411, which restricts the vertical displacement of the walnut during squeezing and improves the success rate of shell breaking. The movable cover plate 37 is placed in the mounting groove of the boss body 331. The movable cover plate 37 has a notch and can be removed, which facilitates the adjustment of the internal structure of the boss body 331.

[0049] To further optimize the technical solution of the present invention, scale lines are provided on both the ratchet adjustment handle 336 and the outer adjustment handle 315 to display the size of the squeezing gap, so as to facilitate the adjustment of the shell-breaking gap according to the size of the walnut.

[0050] Specifically, the power unit 5 includes an electric motor 51, a driving pulley 52, a gearbox 53, a driven pulley 54, and a belt 55. The electric motor 51 is mounted on the frame 1; the driving pulley 52 is mounted on the output shaft of the electric motor 51; the gearbox 53 is mounted on the frame 1; the shaft hole at the center of the bottom of the working disc 341 is mounted on the output shaft of the gearbox 53; the driven pulley 54 is mounted on the input shaft of the gearbox 53. The driving pulley 52 and the driven pulley 54 are connected by a belt 55, achieving a compact and efficient transmission.

[0051] Working principle of the invention:

[0052] The lifting conveyor 6 and motor 51 are started. The lifting conveyor 6 continuously transports walnuts to the feed hopper 2. The walnuts fall from the feed hopper 2 into the shell-breaking space of the shell-breaking device 3. The motor 51 provides power, the drive pulley 52 rotates, and the belt 55 transmits power to the driven pulley 54. The driven pulley 54 drives the input shaft of the gearbox 53 to rotate. The gearbox 53 transmits power to the output shaft of the gearbox 53. The output shaft of the gearbox 53 drives the working disc 341 to rotate. Under the influence of the soft plate 35, the walnuts smoothly enter the working hole 3411, or are blocked by the baffle 38 on the conical surface of the boss body 331. The working disc 341 continues to rotate. Due to the friction between the walnuts and the working disc 341, the position of the walnuts changes irregularly under the rotation of the upper surface of the working disc 341. The walnuts successively fill the working hole 3411. The working disc 341 drives the working hole... The walnut inside 3411 continues to rotate. The working hole 3411 has radially symmetrical inner ring movable push rods 342 and outer ring movable push rods 343 on both sides. When passing the inner ring protrusion 333 on the inner ring 332 and the outer ring protrusion 312 on the shell 311, the inner ring movable push rods 342 and outer ring movable push rods 343 are first compressed by springs, advancing radially on both the inner and outer sides to clamp the walnut. Then, the push rod springs return to equilibrium, and the inner ring movable push rods 342 and outer ring movable push rods 343 release the walnut. Finally, under the action of the circumferentially misaligned arrangement of the outer and inner protrusions, the push rod springs reciprocate through compression and extension, causing the inner ring movable push rods 342 and outer ring movable push rods 343 to alternately vibrate. This vibration adjusts the walnut's posture within the working hole 3411, causing the walnut's stitching line to contact the bottom surface of the working hole 3411, and the walnut is completely embedded in the working hole 3411.

[0053] When the outer adjusting handle 315, ratchet adjusting handle 336, outer movable block 313, and inner movable block 334 are in their initial positions, the outer movable push rod 343 is displaced as it passes the outer movable block 313. Under the action of the outer movable block 313, the spring contracts, and the outer movable push rod 343 is pushed radially. The inner movable block 334 is hinged to the inner ring 332 via the inner hinge 335, forming a cam-like mechanism. The inner movable push rod 342 is not engaged. When the inner movable block 334 is touched, the spring is not under force, and the inner movable push rod 342 has no radial displacement. When the inner movable push rod 342 contacts the highest point of the inner movable block 334, the spring is compressed, and the radial displacement of the inner movable push rod 342 is at its maximum. When the inner movable push rod 342 leaves the inner movable block 334, the spring returns to its original state, and the inner movable push rod 342 has no radial displacement. The outer movable push rod 343 and the inner movable push rod 342 advance radially at the same time, realizing the squeezing and cracking of walnuts with a large radius.

[0054] Rotating the outer adjustment handle 315 clockwise moves it to the left, pushing the outer movable block 313 to rotate clockwise. As the outer movable push rod 343 passes the outer movable block 313, it generates a larger displacement. Under the action of the outer movable block 313, the spring contracts, and the outer movable push rod 343 generates a larger radial push. Rotating the ratchet adjustment handle 336 counterclockwise moves it to the right, pushing the inner movable block 334 to rotate counterclockwise, changing the position of the highest point of the cam-like mechanism. Under the action of the inner movable block 334, when the inner movable push rod 342 contacts the highest point of the cam, the spring is compressed, and the inner movable push rod 342 generates a larger radial push, thus achieving the squeezing and cracking of the shell of the small-radius walnut.

[0055] By rotating the outer adjusting handle 315 and the ratchet adjusting handle 336, the radial distance between the outer movable block 313 and the inner movable block 334 is changed, and the displacement of the outer ring movable push rod 343 and the inner ring movable push rod 342 is changed to accommodate walnuts of different diameters. The shell 31 and the extrusion baffle 36 restrict the vertical displacement of the walnut, so that the walnut completes the shell-breaking process under the shell-breaking gap controlled by the ratchet adjusting handle 336 and the outer adjusting handle 315. Driven by the working disc 341, the rotating wheel 345 has its rotating wheel protrusion 346 inserted into the working hole 3411 in sequence. Under the dual action of gravity and the rotating wheel protrusion 346, the broken walnuts are discharged from the working hole 3411 and fall into the discharge hopper 4. The discharge hopper 4 collects the broken walnuts for subsequent processing and handling.
