Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural product processing machinery, and in particular to an automatic melon core removing device. BACKGROUND

[0002] Melon is an agricultural product that can be eaten or used as a container. When used as a container, the inside of the melon usually needs to be cored. In the case of not cutting open the melon, the traditional cored method is to scratch the inside of the melon with a hook-wired iron wire to remove the core. This method requires a large time cost, and it is difficult to effectively remove the core attached to the inside of the melon. When a large number of melons need to be cored, the traditional manual cored method is very inefficient, and it is difficult to ensure the quality and effect of cored. Currently, mechanical equipment has been used to core melons, but the degree of cored refinement still needs to be improved. CONTENT OF THE INVENTION

[0003] In order to improve the efficiency and refinement of melon cored, the present application provides an automatic melon core removing device.

[0004] The automatic melon core removing device provided by the present application adopts the following technical solution:

[0005] An automatic melon core removing device, comprising:

[0006] an operation table;

[0007] a clamping and positioning mechanism for clamping an inverted melon, the clamping and positioning mechanism being vertically arranged on the operation table;

[0008] a lifting mechanism for driving the clamping and positioning mechanism to vertically move up and down;

[0009] a rough core removing assembly comprising a rotating telescopic brush for rough core removal inside the melon;

[0010] a fine core removing assembly comprising a rotating rope brush for fine core removal inside the melon;

[0011] a brush changing mechanism for changing the position of the telescopic brush and the rope brush, so that the axis of the telescopic brush or the rotating axis of the rope brush is collinear with the axis of the melon.

[0012] The process of removing the pulp from gourds using this application is divided into two stages: coarse pulp removal and fine pulp removal. This is beneficial for improving the fineness of pulp removal and is more efficient than manual pulp removal. In use, the hoist is first inverted and clamped by the clamping and positioning mechanism. Then, the positions of the telescopic brush and rope brush are adjusted by the brush changing mechanism to make the axis of the telescopic brush collinear with the axis of the hoist. Next, the vertical position of the clamping and positioning mechanism is adjusted by the lifting mechanism to allow the telescopic brush to extend into the hoist. The telescopic brush is then rotated to perform coarse de-pulping. After coarse de-pulping, the vertical position of the clamping and positioning mechanism is adjusted by the lifting mechanism to remove the telescopic brush from the hoist. Then, the positions of the telescopic brush and rope brush are adjusted by the brush changing mechanism to make the axis of the rope brush collinear with the axis of the hoist. The vertical position of the clamping and positioning mechanism is then adjusted by the lifting mechanism to allow the rope brush to extend into the hoist. The rope brush is then rotated to perform fine de-pulping. After fine de-pulping, the vertical position of the clamping and positioning mechanism is adjusted by the lifting mechanism to remove the rope brush from the hoist.

[0013] Furthermore, the clamping and positioning mechanism includes a gourd placement platform, one side of which is provided with a slot for accommodating the waist of the gourd; the clamping and positioning mechanism also includes a set of central positioning components and two sets of end positioning components, which are used to clamp and position the middle and both ends of the gourd, respectively.

[0014] First, place the waist of the gourd into the slot of the gourd placement platform to initially position the gourd. Then, use a set of middle positioning components to further clamp and position the middle of the gourd, and use two sets of end positioning components to clamp and position the two ends of the gourd respectively, thereby fixing the gourd on the gourd placement platform.

[0015] Furthermore, the upper surface of the gourd placement platform is provided with an installation groove, and the central positioning component includes a central positioning cone and a movable semi-cone disposed in the installation groove, wherein the movable semi-cone is detachable; both the central positioning cone and the movable semi-cone are semi-circular, and the annular space formed by the two together is used to position the waist of the gourd.

[0016] When positioning the middle part of the gourd, first fix the central positioning cone in the mounting groove, then insert the waist part of the gourd into the slot of the gourd placement platform, and then install the movable semi-circular cone in the mounting groove. At this time, the waist part of the gourd is located in the annular space enclosed by the central positioning cone and the movable semi-circular cone, thus achieving the positioning of the middle part of the gourd.

[0017] Furthermore, each set of the end positioning components includes a mounting plate that is lifted and disposed on the hoist placement platform. A clamping cone is fixedly connected to the side of the mounting plate facing the hoist, and the clamping cone is provided with a groove for accommodating the top or bottom of the hoist.

[0018] After the hoist is positioned in the middle, the mounting plates at both the top and bottom ends of the hoist are moved towards the hoist, causing the two clamping cones to abut against the top and bottom ends of the hoist, clamping and positioning it. The grooves on the clamping cones accommodate the ends of the hoist, helping to improve the stability of the hoist clamping. The cylinder rods of two cylinders extend and retract under constant air pressure, thereby raising and lowering the upper and lower mounting plates respectively, enabling the clamping and positioning of hoists of different heights with a constant clamping force.

[0019] Furthermore, the lifting mechanism includes a lead screw rotatably mounted on the operating table and a guide rod fixedly mounted on the operating table. Both the lead screw and the guide rod are vertical. The lead screw is threadedly connected to the hoist placement platform, and the guide rod passes through the hoist placement platform.

[0020] The rotation of the lead screw drives the hoist placement platform to rise and fall, and the guide rod guides the rise and fall of the hoist placement platform.

[0021] Furthermore, the telescopic brush includes a plurality of elastic support wires and an elastic sleeve covering the plurality of elastic support wires, the outer surface of the elastic sleeve being provided with a protruding structure; the telescopic brush also includes an elastic drive assembly for driving the plurality of elastic support wires to bend simultaneously and supporting the elastic sleeve into a spherical shape.

[0022] Furthermore, the elastic drive assembly includes a brush head shaft and a sleeve rod slidably sleeved on the brush head shaft. The two ends of the elastic support wire are respectively fixed to the end of the brush head shaft and the end of the sleeve rod. An elastic element is provided between the end of the brush head shaft and the end of the sleeve rod to drive the sleeve rod to slide and reset along the brush head shaft.

[0023] When the elastic element is not compressed by external force, there is a certain distance between the end of the brush head shaft and the end of the sleeve rod. The bending degree of the elastic support wire is very small, and the elastic sleeve is not supported by the elastic support wire, which makes it easy for the telescopic brush to extend into the gourd from the mouth of the gourd. As the telescopic brush continues to approach the bottom of the gourd, until the pressure of the bottom wall of the gourd on the end of the brush head shaft overcomes the elastic force of the elastic element, the elastic element is compressed, and the distance between the end of the brush head shaft and the end of the sleeve rod is reduced. This causes multiple elastic support wires to bend simultaneously and support the elastic sleeve into a spherical shape. When the telescopic brush rotates, the protruding structure on the outer surface of the elastic sleeve scrapes inside the gourd, coarsely removing the pulp from the gourd.

[0024] After the coarse pith removal is completed, the telescopic brush moves away from the bottom of the gourd, the pressure of the inner bottom wall of the gourd on the end of the brush head shaft is eliminated, and under the action of the deformation force of the elastic element, the sleeve slides and resets along the brush head shaft, causing the bent elastic support wire to gradually straighten, the elastic sleeve to contract, making it easier to remove the telescopic brush from the gourd.

[0025] Furthermore, the rope brush includes a brush rod and a nylon rope fixed to the brush rod, with a brush head fixedly disposed at the free end of the nylon rope; the nylon rope is a flexible rope, and the brush head is rigid and has barbed protrusions on its surface.

[0026] When the brush rod rotates at high speed, the brush head at the end of the nylon rope adheres tightly to the inner wall of the gourd under centrifugal force. The barbed protrusions on the brush head rub against the inner wall to finely remove the pulp. Furthermore, by adjusting the vertical position of the gourd through the lifting mechanism, the position of the nylon rope inside the gourd can be adjusted, thereby enabling fine pulp removal from various parts of the gourd.

[0027] Furthermore, the brush rod is hollow inside and connected to an external air source, and several air holes are opened on the periphery of the brush rod.

[0028] Gas from an external air source enters the gourd through the air holes on the brush rod, and high-pressure gas is used to flush the inside of the gourd to remove any remaining fine debris. Because the gourd is inverted, the debris is easily flushed out of the gourd opening by its own weight.

[0029] Furthermore, the brush changing mechanism includes a brush changing frame rotatably mounted on the operating table, the rotation axis of the brush changing frame being vertical, and the telescopic brush and the rope brush being rotatably mounted at both ends of the brush changing frame, respectively.

[0030] By rotating the brush changer, the positions of the telescopic brush and the rope brush can be switched; when coarse de-pulping is required, align the telescopic brush with the gourd opening, and when fine de-pulping is required, align the rope brush with the gourd opening.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The clamping and positioning mechanism allows for quick and accurate clamping and positioning of the hoist, facilitating the alignment of the axis of the telescopic brush or rope brush with the axis of the hoist, thus enabling the de-coring process to be completed safely and efficiently; and the clamping and positioning mechanism is applicable to hoists of different sizes.

[0033] 2. The gourd de-pulling operation using this application is divided into two stages: coarse de-pulling and fine de-pulling. First, a telescopic brush is used for coarse de-pulling to provide sufficient working space for subsequent fine de-pulling. Then, by rotating the rope brush at high speed, the brush head will be pressed tightly against the inner wall of the gourd under the action of centrifugal force. The spike-like protrusions on the brush head will be used to rub against the inner wall for fine de-pulling. The combination of the two de-pulling tools helps to reduce the dead corners inside the gourd for de-pulling, improve the fineness of de-pulling, and is more efficient than manual de-pulling.

[0034] 3. Gas from an external air source enters the gourd through the air holes on the brush rod, and high-pressure gas is used to flush the inside of the gourd to remove any remaining fine debris. Since the gourd is inverted, the debris is easily flushed out of the gourd opening by its own weight. Attached Figure Description

[0055] The following is in conjunction with the appendix Figures 1-14 This application will be described in further detail.

[0056] This application discloses an automatic gourd pith removal device. (Refer to...) Figure 1 The automatic de-coring device for a hoist includes an operating platform 102. A clamping and positioning mechanism is vertically mounted on the operating platform 102 for clamping an inverted hoist. The operating platform 102 is also equipped with a lifting mechanism for driving the clamping and positioning mechanism to move up and down vertically.

[0057] To achieve precise de-pigging of the gourd, the automatic de-pigging device provided in this application uses two de-pigging tools in combination: a coarse de-pigging component and a fine de-pigging component. The coarse de-pigging component includes a rotatably mounted telescopic brush 402, and the fine de-pigging component includes a rotatably mounted rope brush 401. A brush-changing mechanism is also provided on the operating table 102 to switch the positions of the telescopic brush 402 and the rope brush 401, ensuring that the axis of the telescopic brush 402 or the rotation axis of the rope brush 401 is collinear with the axis of the gourd.

[0058] Reference Figure 1The clamping and positioning mechanism includes a hoist placement platform 106 that is lifted and mounted on the operating table 102. (See reference...) Figure 2 and Figure 3 The gourd placement platform 106 has a U-shaped bayonet 1064 on one side for accommodating the waist of the gourd. The clamping and positioning mechanism also includes a set of middle positioning components and two sets of end positioning components, which are used to clamp and position the middle and both ends of the gourd, respectively.

[0059] Specifically, refer to Figure 2 and Figure 3 The upper surface of the gourd placement platform 106 has a mounting groove 1063, which is coaxial with the gourd. The central positioning component includes a central positioning cone 209 and a movable semi-cone 210 disposed in the mounting groove 1063. The movable semi-cone 210 is detachable. The central positioning cone 209 can be fixed in the mounting groove 1063 or detachably installed therein. Both the central positioning cone 209 and the movable semi-cone 210 are semi-annular, and the annular space formed by their combination is used to position the waist of the gourd. Both the central positioning cone 209 and the movable semi-cone 210 have arc-shaped grooves that can fit against the surface of the gourd, improving the stability of the gourd's clamping and positioning.

[0060] Reference Figure 4 The end positioning assembly includes an upper mounting plate 205 that is lifted and disposed on the upper end face of the hoist placement platform 106, and a lower mounting plate 207 that is lifted and disposed on the lower end face of the hoist placement platform 106. Specifically, two upper cylinders 201 are symmetrically mounted on the upper end face of the hoist placement platform 106, and an upper connecting plate 203 is fixedly connected to the output end of the upper cylinder 201. The upper connecting plate 203 is fixedly connected to the upper mounting plate 205. Two lower cylinders 202 are symmetrically mounted on the lower end face of the hoist placement platform 106, and a lower connecting plate 204 is fixedly connected to the output end of the lower cylinder 202. The lower connecting plate 204 is fixedly connected to the lower mounting plate 207.

[0061] Furthermore, refer to Figure 4 An upper clamping cone 206 is fixedly connected to the lower end face of the upper mounting plate 205, and a lower clamping cone 208 is fixedly connected to the upper end face of the lower mounting plate 207. The upper clamping cone 206 is provided with an arc-shaped groove for accommodating the bottom of the gourd, and the lower clamping cone 208 is provided with an arc-shaped groove for accommodating the top of the gourd. A circular through hole is provided through the lower clamping cone 208 and the lower mounting plate 207 to facilitate inserting a de-coring tool into the gourd opening through this circular through hole.

[0062] When installing the hoist, first fix the central positioning cone 209 in the installation groove 1063, then invert the hoist and place its waist in the slot 1064 of the hoist placement platform 106, and then install the movable semi-circular cone 210 in the installation groove 1063. At this time, the waist of the hoist is located in the annular space enclosed by the central positioning cone 209 and the movable semi-circular cone 210, thus achieving the positioning of the middle part of the hoist.

[0063] After the hoist is positioned in the middle, the upper mounting plate 205 and lower mounting plate 207 are moved towards the hoist by the upper cylinder 201 and lower cylinder 202 respectively. This causes the upper clamping cone 206 and lower clamping cone 208 to abut against the two ends of the hoist, clamping and positioning it. The arc-shaped grooves of the upper and lower clamping cones 206 and 208 accommodate the ends of the hoist, helping to improve the stability of the hoist clamping. For reliable positioning and clamping, the clamping force of the upper cylinder 201 must be greater than that of the lower cylinder 202. In this way, the hoist is clamped and fixed on the hoist placement platform 106. When it is necessary to release the hoist clamp, the clamping of the lower cylinder 202 must be released first, and then the clamping of the upper cylinder 201 must be released. By extending and retracting the cylinder rods of the upper cylinder 201 and the lower cylinder 202 under constant air pressure, the upper mounting plate 205 and the lower mounting plate 207 are raised and lowered respectively, which can clamp and position hoists of different heights with a constant clamping force.

[0064] The lifting mechanism is used to drive the hoist placement platform 106 to rise and fall. For details, please refer to... Figure 1 The lifting mechanism includes a lead screw 104 rotatably mounted on the operating table 102 and a guide rod 105 fixedly mounted on the operating table 102. Both the lead screw 104 and the guide rod 105 are vertical. A speed-regulating motor 101 for driving the lead screw 104 to rotate is installed under the operating table 102. The output end of the speed-regulating motor 101 is coaxially fixed to the lead screw 104. The lead screw 104 passes through the operating table 102 and is rotatably mounted on the operating table 102 via bearings. (Refer to...) Figure 2 A threaded sleeve 1062 is fixedly installed on one side of the hoist placement platform 106, and the hoist placement platform 106 is threadedly connected to the lead screw 104 through the threaded sleeve 1062; a platform limiting hole 1061 is provided on the hoist placement platform 106 for the guide rod 105 to pass through. In order to prevent the hoist placement platform 106 from rotating, the guide rod 105 is a square rod, and the platform limiting hole 1061 is a square hole.

[0065] The speed-regulating motor 101 drives the lead screw 104 to rotate forward or backward, thereby raising and lowering the hoist placement platform 106 and adjusting the hoist's vertical position. The guide rod 105 guides the raising and lowering of the hoist placement platform 106. To support the lead screw 104 and limit the rise of the hoist placement platform 106, refer to... Figure 1The top end of the guide rod 105 is fixedly connected to the limiting block 107, and the lead screw 104 is rotatably connected to the limiting block 107 through a bearing.

[0066] To achieve coarse pulp removal, refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 The telescopic brush 402 includes multiple elastic support wires 4023 and an elastic sleeve 4025 covering the multiple elastic support wires 4023. The elastic support wires 4023 can be made of elastic steel wire or alloy wire, and the elastic sleeve 4025 can be made of rubber. The outer surface of the elastic sleeve 4025 is uniformly provided with spike-like protrusions. The telescopic brush 402 also includes an elastic drive assembly for driving the multiple elastic support wires 4023 to bend simultaneously and support the elastic sleeve 4025 into a balloon shape.

[0067] Specifically, refer to Figure 6 and Figure 8 The elastic drive assembly includes a brush head shaft 4021 and a sleeve rod 4022 slidably sleeved on the brush head shaft 4021. Two ends of elastic support wires 4023 are respectively fixed to the ends of the brush head shaft 4021 and the sleeve rod 4022. Multiple elastic support wires 4023 are evenly spaced around the circumference of the brush head shaft 4021. The end of the brush head shaft 4021 is fixed to the inner wall of the elastic sleeve 4025, which can be achieved by adhesive bonding. An elastic element is provided between the end of the brush head shaft 4021 and the end of the sleeve rod 4022 to drive the sleeve rod 4022 to slide and reset along the brush head shaft 4021. In this embodiment, the elastic element is a spring 4024 sleeved on the brush head shaft 4021. One end of the spring 4024 is fixed to the end of the brush head shaft 4021 or abuts against the inner wall of the elastic sleeve 4025, and the other end of the spring 4024 is fixed to or abuts against the end of the sleeve rod 4022.

[0068] To prevent relative rotation between the sleeve 4022 and the brush head shaft 4021, a limiting structure can be provided between the sleeve 4022 and the brush head shaft 4021. For example, a protrusion or protrusion (not shown in the figure) can be fixedly provided on the outer wall of the brush head shaft 4021, and a sliding groove (not shown in the figure) can be opened on the inner side wall of the sleeve 4022. The sliding groove extends along the length of the sleeve 4022. The protrusion or protrusion is adapted to slide along the sliding groove, which guides the sliding of the sleeve 4022 along the brush head shaft 4021 and helps to prevent relative rotation between the sleeve 4022 and the brush head shaft 4021.

[0069] Reference Figure 6When the telescopic brush 402 is in its natural state, the spring 4024 is not compressed by external force, the distance between the end of the brush head shaft 4021 and the end of the sleeve 4022 is relatively large, the bending degree of the elastic support wire 4023 is very small, and the elastic sleeve 4025 is not supported by the elastic support wire 4023, making it easy for the telescopic brush 402 to extend into the gourd from the gourd opening. As the telescopic brush 402 approaches the bottom of the gourd, until the pressure of the bottom wall of the gourd on the end of the brush head shaft 4021 overcomes the elastic force of the spring 4024, compressing the spring 4024, the distance between the end of the brush head shaft 4021 and the end of the sleeve 4022 decreases. This causes multiple elastic support wires 4023 to bend simultaneously, supporting the elastic sleeve 4025 into a spherical shape. Figure 8 and Figure 9 As shown, the more elastic support wires 4023 there are, the closer the elastic sleeve 4025 will be to a spherical shape after being supported. The outer surface of the elastic sleeve 4025 is in contact with the inner wall of the gourd. When the telescopic brush 402 rotates, the raised structure on the outer surface of the elastic sleeve 4025 scrapes inside the gourd, coarsely removing the pulp from the gourd.

[0070] After the coarse de-pulping is completed, the gourd rises, the telescopic brush 402 moves away from the bottom of the gourd, and the pressure of the inner bottom wall of the gourd on the end of the brush head shaft 4021 is relieved. Under the action of the deformation force of the spring 4024, the sleeve rod 4022 slides back along the brush head shaft 4021, causing the bent elastic support wire 4023 to gradually straighten, and the elastic sleeve 4025 to contract (as shown). Figure 6 As shown in the figure, this facilitates the removal of the telescopic brush 402 from the gourd.

[0071] Subsequently, a rope brush 401 was used for fine de-peeling, referring to... Figure 10 and Figure 11 The rope brush 401 includes a brush rod 4011 and a nylon rope 4012 fixed to the upper end of the brush rod 4011. A rigid brush head 4013 is fixedly provided at the free end of the nylon rope 4012. The nylon rope 4012 is a flexible rope, and the brush head 4013 can be made of rigid plastic and its surface is provided with barbed protrusions 4014.

[0072] When the brush rod 4011 rotates at high speed, the brush head 4013 at the end of the nylon rope 4012 adheres tightly to the inner wall of the hoist under centrifugal force. The barbed protrusions 4014 on the brush head 4013 rub against the inner wall to perform fine de-pigging. Furthermore, by adjusting the vertical position of the hoist through the lifting mechanism, the position of the nylon rope 4012 inside the hoist can be adjusted, thereby enabling fine de-pigging of various parts inside the hoist and minimizing blind spots in the de-pigging operation.

[0073] To switch between different de-pulping methods, a brush-changing mechanism is needed to change the positions of the telescopic brush 402 and the rope brush 401, as shown in the following figure. Figure 1 and Figure 12The brush changing mechanism includes a brush changing frame 301 rotatably mounted on the operating table 102. The rotation axis of the brush changing frame 301 is vertical. A telescopic brush 402 and a rope brush 401 are rotatably mounted at both ends of the brush changing frame 301, respectively. For details, refer to... Figure 12 The brush changing frame 301 has a first electric drive motor 306 and a second electric drive motor 304 installed at both ends. The output end of the first electric drive motor 306 is connected to the sleeve rod 4022 of the telescopic brush 402 to drive the sleeve rod 4022 to rotate. The output end of the second electric drive motor 304 is connected to the brush rod 4011 of the rope brush 401 to drive the brush rod 4011 to rotate. Two electric drive motor protective covers 305 are also fixedly installed on the brush changing frame 301, respectively covering the first electric drive motor 306 and the second electric drive motor 304. A drive motor 302 is installed on the operating table 102, and the output end of the drive motor 302 is connected to the middle of the brush changing frame 301 to drive the brush changing frame 301 to rotate. A drive motor 302 protective cover is also fixedly installed on the operating table 102 to cover the drive motor 302.

[0074] By rotating the brush changer 301, the positions of the telescopic brush 402 and the rope brush 401 can be switched: when coarse de-pigging is required, rotate the brush changer 301 to align the telescopic brush 402 with the gourd opening; when fine de-pigging is required, rotate the brush changer 301 to align the rope brush 401 with the gourd opening, thus switching between different de-pigging methods.

[0075] To facilitate the cleaning of debris generated during the pulping process, refer to... Figure 10 The brush rod 4011 is hollow inside, and its sidewalls are evenly provided with a large number of air holes. The cavity in the brush rod 4011 is connected to an external air source. In this embodiment, the external air source is... Figure 1 The air compressor 501 in the middle.

[0076] As an example, Figure 12 and Figure 13 The connection method between the brush rod 4011 and the external air source is shown: the second electric drive motor 304 is a hollow shaft motor, and its output end is a through hollow shaft sleeve structure; the brush rod 4011 is coaxially fixed to the output end of the second electric drive motor 304 and passes through the hollow shaft sleeve of the output end of the second electric drive motor 304. A rotary joint 307 is installed on the brush changer 301. The rotary joint 307 includes a fixed part and a rotating part rotatably connected to the fixed part; wherein, the fixed part of the rotary joint 307 is fixed to the brush changer 301, and the rotating part of the rotary joint 307 is coaxially fixed to the end of the brush rod 4011. The fixed part of the rotary joint 307 has an air inlet 3071. One end of the air inlet 3071 is connected to the cavity inside the brush rod 4011 through the air passage inside the rotary joint 307, and the other end of the air inlet 3071 can be connected to the air compressor 501 through an external air pipe (not shown in the figure).

[0077] The high-pressure air generated by the air compressor 501 enters the cavity inside the brush rod 4011 through the air pipe and rotary joint 307, and then enters the inside of the hoist through the air hole on the brush rod 4011 to flush the inside of the hoist with high-pressure gas and remove the fine debris remaining inside the hoist. Since the hoist is inverted, the debris is easily flushed out of the hoist opening by its own weight.

[0078] In order to collect the ejected debris, refer to Figure 1 and Figure 14 A chip collection tray 103 is fixedly installed on the upper surface of the operating table 102. The edges of the chip collection tray 103 are provided with raised ridges to help prevent chips from slipping off the edges. A tray opening 1034 is provided on one side of the chip collection tray 103 to facilitate the emptying and discharge of the collected chips. A drive motor mounting hole 1033 is provided on the chip collection tray 103 for mounting the drive motor 302; a square hole 1031 and a lead screw hole 1032 are also provided on the chip collection tray 103 for the guide rod 105 and the lead screw 104 to pass through, respectively. The lead screw 104 is rotatably mounted on the chip collection tray 103 via bearings.

[0079] The implementation principle of the automatic gourd de-pigging device according to this application embodiment is as follows: The gourd de-pigging operation using this application is divided into two stages: coarse de-pigging and fine de-pigging. First, the gourd is inverted and clamped and fixed on the gourd placement platform 106. Then, the brush changing frame 301 is rotated so that the telescopic brush 402 is aligned with the gourd opening. Then, the gourd placement platform 106 is driven to descend by the lifting mechanism, so that the telescopic brush 402 extends into the gourd. Then, the telescopic brush 402 is rotated to perform coarse de-pigging on the gourd. After the coarse de-pigging is completed, the lifting mechanism... The hoist placement platform 106 is raised to remove the telescopic brush 402 from the inside of the hoist. Then, the brush changer 301 is rotated to align the rope brush 401 with the hoist opening. The hoist placement platform 106 is then lowered via the lifting mechanism to allow the rope brush 401 to extend into the hoist. The rope brush 401 is then rotated and flushed with high-pressure gas through the air hole on the brush rod 4011 to perform fine de-pigging of the hoist. After fine de-pigging is completed, the hoist placement platform 106 is raised again via the lifting mechanism to remove the rope brush 401 from the inside of the hoist.

[0080] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
