Description

Technical Field

[0001] This invention relates to the field of chestnut deburring technology, and more particularly to a deburring device for chestnut processing. Background Technology

[0002] In the prior art, chestnuts, as a type of nut food, have high nutritional value and edible value. After chestnuts are harvested when ripe, the fruit is covered with a spiky shell. Therefore, a deburring device is needed to remove the spiky shell before the chestnut fruit can be taken out. Currently, for small batches of chestnuts, manual removal of the spiky shell is usually done using tools such as pliers. However, for large batches of chestnuts, the efficiency of removing the spiky shell is low. Therefore, this application proposes a deburring device for chestnut processing, which can effectively improve the deburring efficiency.

[0003] A search revealed Chinese patent application number 201810024275.7, which discloses a deburring device for chestnut processing. The device includes a housing, a motor base fixedly connected to the top left side of the housing, a motor fixedly connected above the motor base, an upper rotating shaft fixedly connected to the motor output end via a coupling, a driving bevel gear fixedly connected to the middle of the upper rotating shaft, a longitudinal rotating shaft rotatably connected to the top center of the housing via a bearing, a driven bevel gear fixedly connected to the top of the longitudinal rotating shaft, the driven bevel gear meshing with the driving bevel gear, a rotating rod fixedly connected to the outer side of the lower end of the longitudinal rotating shaft, and cranks fixedly connected to the left and right sides of the upper rotating shaft. An upper connecting rod is rotatably connected below the cranks, and a lower connecting rod is rotatably connected below the upper connecting rod.

[0004] The deburring device for chestnut processing in the aforementioned patent has the following shortcomings: when the chestnut is pressed by the rotating plate and the clamping teeth, the lack of a corresponding positioning mechanism causes the chestnut to slip and become unstable in its burrs, thus failing to successfully remove the burrs. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a deburring device for chestnut processing.

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

[0007] A deburring device for chestnut processing includes a base and a deburring section, the deburring section comprising:

[0008] Support bracket: It is fixed to the top outer wall of the base, and a drive motor is fixed to the top outer wall of the support bracket;

[0009] Threaded rod: It is fixed to the output end of the drive motor by a pin;

[0010] Guide rod: It is fixed to the inner wall of the top of the bracket by a pin, and a disc seat is movably connected to the outer wall of the guide rod.

[0011] Bending rod: It is welded to the outer wall of the top of the disc base, and a lifting block adapted to the threaded rod is welded to the end of the bending rod away from the disc base;

[0012] The receiving frame is welded to the outer wall of the bottom of the tray base, and an adjusting arm is movably connected to the inner wall of the receiving frame. A swing arm is movably connected to the end of the adjusting arm away from the receiving frame, and an expansion plate is welded to the outer wall of the swing arm.

[0013] Mounting cylinder: A mounting bracket is welded to its bottom outer wall, and the swing arm and the mounting bracket are movably connected by a rotating shaft;

[0014] Electric telescopic rod two: It is fixed to the inner wall of the bottom of the mounting cylinder by a pin, and the output end of electric telescopic rod two is fixed with an electromagnet by a pin;

[0015] Conical crusher head: It is welded to the outer wall of the bottom of the mounting cylinder.

[0016] Preferably, a limiting shell is fixed to the inner wall of one side of the bracket, and the inner walls of the through holes on both sides of the limiting shell are movably connected to the same upright rod. A flap is fixed to the outer wall of the upright rod by a pin, and a retaining ring is welded to the outer wall of one side of the flap.

[0017] Preferably, the outer circumferential wall of the limiting shell is welded with an annular shell, and the outer circumferential wall of the upright and the inner wall of the annular shell are fixed together by a pin with the same coil spring.

[0018] Preferably, a connecting rod is welded to the outer wall of the top of the disc base, and a sleeve is fixed to the end of the connecting rod away from the disc base by a pin. A sliding rod is movably connected to the inner wall of the sleeve, and a spring is fixed between one end of the sliding rod and the inner wall of one side of the sleeve by a pin.

[0019] Preferably, an L-shaped plate is welded to the outer wall of the bottom of the slide rod, and a toggle plate is welded to one end of the upright rod, with rollers adapted to the L-shaped plate movably connected to the inner wall of the toggle plate.

[0020] Preferably, a pressing block is fixed to the top outer wall of the base.

[0021] Preferably, an inclined feeding box is fixed to the top outer wall of the base, and a feeding hole is opened at one end of the inclined feeding box.

[0022] Based on the aforementioned scheme: a rectangular plate is fixed to the top outer wall of the base, and an electric telescopic rod is fixed to one side outer wall of the rectangular plate, with a push plate fixed to the output end of the electric telescopic rod by a pin.

[0023] Based on the aforementioned scheme, the preferred embodiment is as follows: a T-shaped rod is welded to one side of the outer wall of the push plate, and a pressure plate is movably connected to the outer circumference of the T-shaped rod, and the same spring is fixed between the outer wall of the pressure plate and the inner wall of the T-shaped rod by a pin.

[0024] A further preferred embodiment based on the aforementioned scheme is that an extrusion ring is welded to one side of the outer wall of the pressure plate.

[0025] The beneficial effects of this invention are as follows:

[0026] 1. The chestnuts to be processed can be positioned and placed by the retaining ring. The conical crushing head can puncture the top of the chestnut with pressure, so that the expansion plate can be inserted into the burr shell. The rotation of the expansion plate can open the burr shell by external expansion, thereby initially separating the chestnut fruit from the burr shell.

[0027] 2. The L-shaped plate can press the roller, allowing the flip plate and retaining ring to rotate automatically to a horizontal position. The pressing block can support and limit the bottom of the flip plate. After the chestnut and the burr shell are separated, the spring force of the coil spring can restore the flip plate and retaining ring to the tilted position, allowing the chestnut and the burr shell to slide down the flip plate surface.

[0028] 3. The chestnut fruit and the burr-like outer shell are initially separated by a slanted feeding box. The chestnut fruit can be discharged through the feeding hole, while the burr-like outer shell remains in the slanted feeding box, thus achieving separation between the two.

[0029] 4. When the electric telescopic rod drives the push plate to move laterally, it can push the burr shell so that the burr shell can be pushed out from one side of the inclined feed box after being pushed, thus avoiding excessive accumulation of the burr shell on the inclined feed box.

[0030] 5. When the burr shell and chestnut are not completely separated by the conical crushing head and the expansion plate, the L-shaped plate can block the outer wall of one side of the pressure plate as it moves downward. At this time, when the electric telescopic rod drives the push plate to move laterally, the pressure plate can remain stationary, while the push plate can gradually move closer to the surface of the pressure plate. At this time, the push plate can push the not completely separated burr shell and chestnut towards the extrusion ring. The pressure applied between the chestnut and burr shell by the push plate causes the chestnut and burr shell to be separated a second time. Attached Figure Description

Detailed Implementation

[0041] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0042] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0043] Example 1:

[0044] A deburring device for chestnut processing, such as Figure 1-9 As shown, it includes a base 1 and a burr removal section, the burr removal section comprising:

[0045] Support 5: It is fixed to the top outer wall of the base 1 by bolts, and the top outer wall of the support 5 is fixed with a drive motor 4 by bolts;

[0046] Threaded rod 9: It is fixed to the output end of drive motor 4 by a pin;

[0047] Guide rod 13: It is fixed to the inner wall of the top of the bracket 5 by a pin, and the outer wall of the guide rod 13 is slidably connected to the disc seat 14.

[0048] Bending rod 10: It is welded to the top outer wall of the disc base 14, and a lifting block 15 adapted to the threaded rod 9 is welded to the end of the bending rod 10 away from the disc base 14.

[0049] The receiving frame 19 is welded to the bottom outer wall of the plate base 14, and the inner wall of the receiving frame 19 is rotatably connected to an adjusting arm 20. The end of the adjusting arm 20 away from the receiving frame 19 is rotatably connected to a swing arm 12, and the outer wall of the swing arm 12 is welded to an expansion plate 22.

[0050] Mounting cylinder 16: A mounting bracket 23 is welded to its bottom outer wall, and the swing arm 12 and the mounting bracket 23 are rotatably connected by a rotating shaft 21;

[0051] Electric telescopic rod 2 40: It is fixed to the inner wall of the bottom of the mounting cylinder 16 by a pin, and an electromagnet 39 is fixed to the output end of the electric telescopic rod 2 40 by a pin;

[0052] Conical crushing head 11: It is welded to the bottom outer wall of the mounting cylinder 16;

[0053] When deburring chestnuts, a drive motor 4 drives the threaded rod 9 to rotate, causing the lifting block 15 to drive the disc base 14 to move vertically downwards under the guidance of the guide rod 13. An electromagnet 39, when energized, can adhere to the bottom outer wall of the disc base 14, thus achieving adsorption and fixation. An electric telescopic rod 40 adjusts the vertical distance between the disc base 14 and the bottom of the mounting cylinder 16. When the output position of the electric telescopic rod 40 remains constant, the conical crushing head 11 first punctures the chestnut's burr shell by insertion as it moves downwards. The expansion plate 22 then applies pressure... Under the action of the electric telescopic rod 40, the output end of the electric telescopic rod 40 drives the electromagnet 39 to move downward. At the same time, the drive motor 4 drives the plate base 14 to move downward in the vertical direction, and the moving speed of the plate base 14 and the moving speed of the output end of the electric telescopic rod 40 are kept the same. During this process, the angle between the adjusting arm 20 and the swing arm 12 changes, so that the expansion plate 22 can expand outward with the swing arm 12. During the synchronous rotation of multiple expansion plates 22, the burr shell can be expanded outward, thereby dividing the burr shell into multiple petals, so that the chestnut fruit can be separated from the burr shell.

[0054] Furthermore, a limiting shell 29 is fixed to one side of the inner wall of the bracket 5 by bolts. The inner walls of the through holes on both sides of the limiting shell 29 are rotatably connected to the same upright rod 31. A flap 28 is fixed to the outer circumference of the upright rod 31 by pins, and a retaining ring 30 is welded to one side of the outer wall of the flap 28. An annular shell 27 is welded to the outer circumference of the limiting shell 29, and the same coil spring 26 is fixed between the outer circumference of the upright rod 31 and the inner wall of the annular shell 27 by pins.

[0055] When it is necessary to deburr chestnuts, the flap 28 and retaining ring 30 are rotated to a horizontal position. The retaining ring 30 can be used to place the chestnuts and limit their movement. When the conical crushing head 11 is pressed onto the chestnut, the force transmission allows the flap 28 and retaining ring 30 to remain in a horizontal position temporarily. After the chestnut fruit and the burred shell are separated, the spring force of the coil spring 26 is used to rotate the flap 28 and retaining ring 30 to an inclined state, so that the chestnut fruit and the burred shell can slide down the surface of the flap 28.

[0056] Furthermore, a pressing block 34 is fixed to the top outer wall of the base 1 by bolts;

[0057] By providing a pressing block 34, the bottom outer wall of the flip plate 28 can be rotated to contact the top of the pressing block 34, which can provide support for the bottom of the flip plate 28.

[0058] Furthermore, a connecting rod 17 is welded to the top outer wall of the disc base 14. A sleeve 3 is fixed to the end of the connecting rod 17 away from the disc base 14 by a pin. A sliding rod 8 is slidably connected to the inner circumference of the sleeve 3. A spring 18 is fixed between one end of the sliding rod 8 and one side inner wall of the sleeve 3 by a pin. An L-shaped plate 2 is welded to the bottom outer wall of the sliding rod 8. A toggle plate 25 is welded to one end of the upright rod 31. A roller 24 adapted to the L-shaped plate 2 is rotatably connected to the inner wall of the toggle plate 25.

[0059] By setting an L-shaped plate 2 to press against the surface of the roller 24 after it moves down, the roller 24 can roll along the lower surface of the L-shaped plate 2 during its downward movement, thereby achieving automatic selection of the flip plate 28 and the retaining ring 30. When the bottom of the flip plate 28 presses against the top of the pressing block 34, the spring 18 undergoes elastic deformation as the L-shaped plate 2 continues to move down, allowing the conical crushing head 11 to continue to move down to remove the burrs from the chestnut shell.

[0060] In this embodiment, when it is necessary to separate the chestnut fruit from the burr-like outer shell, the drive motor 4 first drives the threaded rod 9 to rotate, so that the disc base 14 can drive the conical crushing head 11 to move downwards in the vertical direction under the guidance of the guide rod 13. During this process, the L-shaped plate 2 presses the surface of the roller 24 as it moves downwards, so that the roller 24 and the actuating plate 25 can drive the upright rod 31 and the flip plate 28 to rotate. When the bottom of the flip plate 28 presses against the top of the pressing block 34, the pressing block 34 limits the flip plate 28, so that the flip plate 28 can always remain in a horizontal state. Then, the chestnut is placed in the retaining ring 30. As the conical crushing head 11 continues to move downwards, it can pierce the top of the chestnut. At the same time, the expansion plate 22 can apply pressure. When the conical crushing head 11 extends into the inner wall of the burr shell, the electric telescopic rod 40 drives the electromagnet 39 to move downward. The electromagnet 39 magnetically attracts the lower surface of the disc base 14, which can drive the disc base 14 to move downward, causing the swing arm 12 and the adjusting arm 20 to expand towards the shell. During the expansion process, the expansion plate 22 can expand the burr shell, making the chestnut burr shell into a petal shape after expansion, so that the chestnut fruit can be initially separated from the burr shell. When the conical crushing head 11 moves in the opposite direction to reset, when the L-shaped plate 2 disengages from the surface of the roller 24, the flip plate 28 and the retaining ring 30 can be reset under the elastic action of the coil spring 26. When the flip plate 28 and the retaining ring 30 tilt, the chestnut fruit and the burr shell slide down along the surface of the flip plate 28.

[0061] Example 2:

[0062] A deburring device for chestnut processing, such as Figure 1-9As shown, in order to facilitate the separate feeding of chestnut fruit and burr shell, this embodiment makes the following additions based on embodiment 1: the top outer wall of the base 1 is fixed with an inclined feeding box 7 by bolts, one end of the inclined feeding box 7 is provided with a feeding hole, the top outer wall of the base 1 is fixed with a rectangular plate 33 by bolts, one side outer wall of the rectangular plate 33 is fixed with an electric telescopic rod 6 by bolts, and the output end of the electric telescopic rod 6 is fixed with a push plate 38 by a pin;

[0063] After the chestnuts and their burrs have been initially removed, they fall into the inclined feeding box 7 and slide down its slope. The diameter of the feeding hole on the surface of the inclined feeding box 7 is smaller than that of the burr shells but larger than that of the chestnuts, allowing the chestnuts to be fed through the feeding hole. The burr shells remain on the inclined feeding box 7. When the electric telescopic rod 6 drives the push plate 38 to move laterally, it can push the burr shells, allowing them to be pushed out from one side of the inclined feeding box 7, thus preventing excessive accumulation of burr shells on the inclined feeding box 7.

[0064] Furthermore, a T-shaped rod 32 is welded to one side of the outer wall of the push plate 38, and a pressure plate 36 is slidably connected to the outer circumference of the T-shaped rod 32. The same spring 35 is fixed between the outer wall of one side of the pressure plate 36 and the inner wall of one side of the T-shaped rod 32 by a pin. A compression ring 37 is welded to one side of the outer wall of the pressure plate 36.

[0065] When the burr shell and chestnut are not completely separated by the conical crushing head 11 and the expansion plate 22, the L-shaped plate 2 can block one side of the outer wall of the pressure plate 36 during its downward movement. At this time, when the electric telescopic rod 6 drives the push plate 38 to move laterally, the pressure plate 36 can remain stationary, while the push plate 38 can gradually approach the surface of the pressure plate 36. At this time, the push plate 38 can push the not completely separated burr shell and chestnut towards the extrusion ring 37. When the chestnut and burr shell come into contact with the surface of the extrusion ring 37, the pressure applied between the chestnut and burr shell by the push plate 38 causes the chestnut and burr shell to separate a second time. When the L-shaped plate 2 moves upward and resets, it detaches from one side of the outer wall of the pressure plate 36. At this time, the pressure plate 36 can spring open under the action of the spring force of the second spring 35, making it easier for the push plate 38 to push out the separated burr shell.

[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present 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 the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
