Description

Technical Field

[0001] This invention relates to the field of food processing machinery technology, and in particular to a device and method for removing pickled mustard tubers from the vat. Background Technology

[0002] As a traditional Chinese pickled vegetable, the fermentation process is crucial in the production of pickled mustard tuber, directly affecting its flavor and quality. In industrial production, pickled mustard tuber typically undergoes long-term natural or temperature-controlled fermentation in large fermentation tanks or fermentation vessels. After the fermentation cycle is complete, the fermented mustard tuber needs to be removed from the tank for subsequent cleaning, cutting, seasoning, and packaging. Currently, the removal of pickled mustard tuber from the tank mainly relies on manual labor using simple tools or basic hoisting equipment for overall lifting. In the traditional manual operation mode, workers need to enter or approach the edge of the fermentation tank and use tools such as strainers and tongs to scoop out the mustard tuber and load it into transfer containers. In semi-mechanized scenarios, overhead cranes or hoists are typically used to vertically lift the baskets containing the mustard tuber, and then workers manually assist in pouring them into the next stage's conveyor equipment or storage containers.

[0003] However, in existing technologies, the process of removing pickled mustard tubers from the fermentation tank still suffers from low operational efficiency, high labor intensity, and insufficient automation. Because the fermentation tank environment is humid and space is limited, manual handling is not only time-consuming and labor-intensive, but also makes it difficult to ensure the continuity and stability of material transfer, resulting in limited production cycle time and failing to meet the demands of large-scale industrial production for efficient flow. Summary of the Invention

[0004] The purpose of this invention is to provide a device and method for removing pickled mustard tubers from the fermentation tank, which can solve the technical problems of low efficiency, high labor intensity and difficulty in automation caused by traditional manual or inefficient equipment for removing pickled mustard tubers from the fermentation tank.

[0005] The first aspect of this application provides a pickled mustard tuber removal device, including a moving component, a material-collecting component, and a storage component. The moving component includes a base, a first moving wheel, and a support frame. The support frame is fixedly connected to the base and located on top of the base. The first moving wheel is rotatably disposed at the bottom of the base. The material-collecting component includes a lifting cylinder, a lifting plate, a rotating shaft, a rotating box, a gear, a rack, and a gripper structure. The lifting cylinder is fixed to the support frame. The lifting plate is connected to the output end of the lifting cylinder. The rotating box is rotatably disposed on the lifting plate. The gear is fixedly connected to the rotating box. The rack is fixed to one side of the support frame and is used to engage with the gear after the rotating box rises to a preset height to drive the rotating box to rotate and pour out the pickled mustard tuber. The gripper structure is disposed below the rotating box for gripping the pickled mustard tuber. The storage component is disposed on one side of the support frame for collecting the pickled mustard tuber poured out from the rotating box.

[0006] The base includes a base body and an extension rod. The extension rod is slidably connected to the base body and is located on one side of the base body. A first movable wheel is rotatably mounted on the extension rod.

[0007] The rotating box includes a box body and a counterweight. The counterweight is fixed to the box body and is used to keep the box body in a vertical position when the gear is not in contact with the rack.

[0008] The gripper structure includes a control cylinder, a push ring, multiple control levers, and multiple rotating claws. The multiple rotating claws are rotatably mounted on the housing and located around the perimeter of the housing. The push ring is slidably mounted on the outside of the housing. One end of each of the multiple control levers is rotatably connected to the push ring, and the other end of each of the multiple control levers is rotatably connected to the multiple rotating claws. The output end of the control cylinder is connected to the push ring.

[0009] The rotating claw includes a claw body and a buffer bar. The claw body is provided with a leakage hole, and the buffer bar is located on one side of the claw body.

[0010] The gripper structure also includes a return spring, which is located between the control cylinder and the push ring.

[0011] The storage components include a conveyor, a placement plate, and a storage box. The conveyor is fixed to a support frame and located on one side of the box. The placement plate is fixed to the support frame and is used to place the storage box.

[0012] The conveyor includes a support plate and a conveyor line. The support plate is fixed to the support frame, and the conveyor line is rotatably mounted on the support plate.

[0014] The second aspect of this application provides a method for removing pickled mustard tubers from the vat, using the pickled mustard tuber removal device described in any of the preceding claims.

[0015] This application provides a device and method for removing pickled mustard tubers from the fermentation tank. This solution integrates a moving component, a material-collecting component, and a storage component to construct a fully automated operation system from grasping to temporary storage. Specifically, the device is flexibly positioned next to the fermentation tank using a base and first moving wheels in the moving component. A lifting cylinder drives a lifting plate to raise a rotating box. During this process, when the rotating box reaches a preset height, its gears mesh with a rack fixed to a support frame. As the lifting motion continues, the gears climb along the rack, driving the rotating box to automatically rotate around its axis, causing the pickled mustard tubers inside to tilt into the storage component under gravity. Simultaneously, a gripper structure located below the rotating box cooperates to complete the initial grasping and release of the material, thus achieving mechanical linkage tilting without the need for an additional power source for tilting. This series of actions effectively solves the problems of low efficiency and high labor intensity caused by traditional manual retrieval or simple hoisting, ensuring the continuity and stability of the tank-removing operation. Furthermore, by using storage components to collect and temporarily store the poured-out pickled mustard tubers in an orderly manner, the material is prevented from being scattered and piled up, and the efficiency of subsequent processes is improved. The overall solution significantly improves the automation level and operational safety of pickled mustard tuber production and processing.

[0016] In summary, this application forms a complete, reliable, and efficient closed-loop technology for pickled mustard tuber removal by precise coordination and logical linkage among various components. It not only optimizes the execution accuracy of individual actions but also achieves smooth and controllable material flow at the system level, providing strong technical support for the mechanization upgrade of the pickled vegetable industry.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] First embodiment: In the production and processing of pickled mustard tubers, the tubers need to be pickled and fermented in fermentation tanks. Traditionally, the process of removing the tubers from the fermentation tanks relies mainly on manual labor. Workers need to enter the fermentation tanks or use simple tools to move the heavy jars or bulk tubers to transport vehicles or subsequent processing equipment. This method is not only labor-intensive and inefficient, but also poses significant safety hazards due to the humid and confined environment inside the fermentation tanks. While some existing mechanized equipment can assist in handling, it often has limited functionality and cannot achieve full automation of the entire process from grabbing and lifting to automatic dumping and unloading. This results in poor overall continuity of the process and fails to meet the needs of modern large-scale production.

[0022] To address the aforementioned issues, this application provides a pickled mustard tuber removal device, which aims to automatically grab, lift, flip, pour, and collect pickled mustard tubers through the coordinated operation of mechanical structures, thereby improving the automation level and work efficiency of the removal operation.

[0023] Based on the above issues, please refer to Figure 1-4This application provides a pickled mustard tuber removal device, including a moving component 1, a material-collecting component 2, and a storage component 3. The moving component 1 includes a base 101, a first moving wheel 102, and a support frame 103. The support frame 103 is fixedly connected to the base 101 and located on top of the base 101. The first moving wheel 102 is rotatably disposed at the bottom of the base 101. The material-collecting component 2 includes a lifting cylinder 201, a lifting plate 202, a rotating shaft 203, a rotating box 204, a gear 205, a rack 206, and a gripper structure 207. The lifting cylinder 201 is fixed to the support frame 3. On the support frame 103, the lifting plate 202 is connected to the output end of the lifting cylinder 201. The rotating box 204 is rotatably mounted on the lifting plate 202. The gear 205 is fixedly connected to the rotating box 204. The rack 206 is fixed to one side of the support frame 103. It is used to drive the rotating box 204 to rotate after the rotating box 204 rises to a preset height, so as to pour out the pickled mustard tuber. The gripper structure 207 is located below the rotating box 204 and is used to grab the pickled mustard tuber. The storage component 3 is located on one side of the support frame 103 and is used to collect the pickled mustard tuber poured out from the rotating box 204.

[0024] The core innovation of this application lies in constructing a mechanical structure that integrates lifting and tilting control through the linkage of gear 205 and rack 206. The working process and principle of this application are as follows: the device moves to the work point via the moving component 1; after the gripper structure 207 grabs the pickled mustard tuber, the lifting cylinder 201 drives the lifting plate 202 and the rotating box 204 to rise; when it rises to the preset height, the gear 205 fixed on the rotating box 204 meshes with the rack 206 fixed on the support frame 103; as the lifting action continues, the gear 205 rolls along the rack 206, forcing the rotating box 204 to rotate around the rotating shaft 203, thereby pouring the pickled mustard tuber into the storage component 3; the entire process utilizes a lifting power source to simultaneously complete both lifting and tilting actions, requiring no additional drive source.

[0025] As a preferred embodiment, the solution of this application is implemented as follows: The operator pushes the device to the side of the fermentation tank, starts the control system, the gripper structure 207 descends and closes, grabbing the container containing pickled mustard tubers; then the lifting cylinder 201 retracts, driving the lifting plate 202 and the rotating box 204 to move upward; when the rotating box 204 rises to the preset position in the middle of the support frame 103, the gear 205 contacts and begins to mesh with the rack 206; the lifting cylinder 201 continues to retract, the gear 205 climbs upward along the rack 206, driving the rotating box 204 to rotate approximately 90 to 180 degrees; at this time, the pickled mustard tubers in the rotating box 204 (or the pickled mustard tubers released from the gripper structure 207 and falling into the rotating box 204) slide down onto the conveyor belt of the storage component 3 located on the side below under the action of gravity; after unloading is completed, the lifting cylinder 201 retracts, the gear 205 rolls in the opposite direction along the rack 206, driving the rotating box 204 to return to the vertical state, and the device is ready for the next operation.

[0026] Through the above technical solution, this application achieves the following beneficial effects: Because of the meshing transmission mechanism of gear 205 and rack 206, the linear motion of the lifting cylinder 201 is directly converted into the rotational motion of the rotating box 204, thus eliminating the need for a separate tilting motor or hydraulic motor, simplifying the equipment structure and control system, and reducing the failure rate; Because the gripper structure 207 is integrated with the rotating box 204 and lifts and lowers synchronously, continuous operation from gripping to pouring is achieved, reducing intermediate transfer links and significantly improving the efficiency of pickled mustard tuber removal; Because the storage component 3 is located on one side of the support frame 103, it can promptly receive the poured pickled mustard tuber, avoiding material contamination upon impact and improving the hygiene and safety of the working environment.

[0027] The base 101 includes a base body 1011 and an extension rod 1012. The extension rod 1012 is slidably connected to the base body 1011 and is located on one side of the base body 1011. The first moving wheel 102 is rotatably mounted on the extension rod 1012.

[0028] When the pickled mustard tuber extraction device needs to move between fermentation tanks of different widths or operate on uneven ground, the operator or drive mechanism pushes the extension rod 1012 to slide relative to the base body 1011. If the ground is soft or stability needs to be increased, the extension rod 1012 is pulled outward, causing the first moving wheel 102 to move outward, increasing the effective support area and wheelbase of the base 101, and reducing the risk of tipping over due to a shift in the device's center of gravity. If it is necessary to pass through narrow doorways or save space in storage mode, the extension rod 1012 is pushed into the base body 1011, shortening the overall length. During this process, the first moving wheel 102 always rolls in contact with the ground, working in conjunction with the support of the base body 1011 to drive the entire device to move smoothly, providing a stable foundation for the precise positioning of the upper material extraction component 2.

[0029] Through the above technical solution, this application achieves the following: because the base 101 adopts a structure in which the base body 1011 and the extension rod 1012 are slidably connected, and the first moving wheel 102 is set on the extension rod 1012, the device can dynamically adjust its length and wheel spacing according to the size of the space and the ground conditions of the working environment. This solves the technical problems of insufficient mobility and easy overturning of existing fixed bases in fermentation tanks of different sizes or complex terrains, and achieves the technical effects of enhancing the device's terrain adaptability, improving transportation convenience, and ensuring the stability of the operation process.

[0030] The rotating box 204 includes a box body 2041 and a counterweight 2042. The counterweight 2042 is fixed to the box body 2041 and is used to keep the box body 2041 in a vertical state when the gear 205 is not in contact with the rack 206.

[0031] The counterweight 2042 refers to a solid component with a specific mass, and its material can be metal, concrete, or high-density composite material, etc., which is not specifically limited in this embodiment. The counterweight 2042 is fixedly installed at a specific position on the box 2041, for example, it can be fixed to one side of the bottom of the box 2041 or the lower part of the side wall. The counterweight 2042 and the box 2041 together constitute an integral structure with a specific center of gravity distribution; by adjusting the mass of the counterweight 2042 and its installation position relative to the rotation axis 203, the static equilibrium point of the box 2041 in the free state can be changed. In this scheme, the function of the counterweight 2042 is to provide restoring torque: when the box 2041 tilts slightly due to inertia or vibration, the gravitational torque generated by the counterweight 2042 can cause the box 2041 to automatically return to a vertical state, thereby forming a time-sequence logical interlock with the action of the gear 205 and the rack 206, ensuring that the box 2041 only performs the flipping and unloading action when the gear 205 climbs to the preset height of the rack 206 and generates sufficient driving torque.

[0032] Furthermore, the gripper structure 207 includes a control cylinder 2071, a push ring 2072, multiple control levers 2073, and multiple rotating claws 2074. The multiple rotating claws 2074 are rotatably mounted on the housing 2041 and located around the housing 2041. The push ring 2072 is slidably mounted on the outside of the housing 2041. One end of the multiple control levers 2073 is rotatably connected to the push ring 2072, and the other end of the multiple control levers 2073 is rotatably connected to the multiple rotating claws 2074 respectively. The output end of the control cylinder 2071 is connected to the push ring 2072.

[0033] When it is necessary to grab the pickled mustard tuber, the control cylinder 2071 is vented and extended, causing the push ring 2072 to slide downward. The downward movement of the push ring 2072 pushes the lower ends of multiple rotating claws 2074 to swing inward through the hinge points of multiple control rods 2073, thereby causing the multiple rotating claws 2074 to converge towards the center and clamp the pickled mustard tuber located below the box 2041, thus making it more convenient to grab.

[0034] The rotating claw 2074 includes a claw body 20741 and a buffer bar 20743. The claw body 20741 is provided with a leakage hole 20742, and the buffer bar 20743 is provided on one side of the claw body 20741.

[0035] When it is necessary to pickle the pickled mustard tuber, the buffer strip 20743 on the claw body 20741 contacts and clamps the pickled mustard tuber. Excess brine on the surface of the pickled mustard tuber flows out through the drain hole 20742 on the claw body 20741 under the action of gravity, realizing the draining function under the clamping state. Subsequently, the entire material picking assembly 2 rises. When the rotating box 204 reaches the unloading height and meshes with the rack 206 to flip, the control cylinder 2071 moves in the opposite direction, driving the rotating claw 2074 to open. The pickled mustard tuber falls into the storage assembly 3 under the action of gravity, completing one retrieval operation.

[0036] The gripper structure 207 also includes a return spring 2075, which is disposed between the control cylinder 2071 and the push ring 2072.

[0037] When the control cylinder 2071 drives the push ring 2072 to move axially to perform a gripping action, the return spring 2075 is compressed or stretched to store elastic potential energy; when the control cylinder 2071 removes the driving force or loses power due to a malfunction, the return spring 2075 releases the stored energy and generates a restoring force to push the push ring 2072 back to the initial position.

[0038] The storage assembly 3 includes a conveyor 301, a placement plate 302, and a storage box 303. The conveyor 301 is fixed on the support frame 103 and located on one side of the box body 2041. The placement plate 302 is fixed on the support frame 103 and is used to place the storage box 303.

[0039] When the lifting cylinder 201 drives the lifting plate 202 to rise to the preset height, the gear 205 meshes with the rack 206 to rotate the rotating box 204, and the pickled mustard tuber in the box 2041 is poured out. The poured-out pickled mustard tuber falls into the conveyor 301 located on one side of the box 2041, slides down the conveyor 301 and finally enters the storage box 303 placed on the placement plate 302. In this process, the conveyor 301 plays a guiding role and the placement plate 302 plays a stable supporting role. The two work together to ensure a smooth transition of the pickled mustard tuber from dynamic pouring to static storage.

[0040] The conveyor 301 includes a support plate 3011 and a conveyor line 3012. The support plate 3011 is fixed to the support frame 103, and the conveyor line 3012 is rotatably mounted on the support plate 3011.

[0041] After the material-grabbing component 2 finishes grabbing the pickled mustard tuber and rotates the rotating box 204 to the pouring angle, the pickled mustard tuber slides from the rotating box 204 into the conveyor 301. At this time, the conveyor line 3012 located in the conveyor 301 begins to rotate under the pressure of gravity and friction of the pickled mustard tuber (if it is a non-powered roller conveyor, it rotates passively with the movement of the material; if it is a powered conveyor line, it is driven by a drive source). The rotation of the conveyor line 3012 changes the friction between the pickled mustard tuber and the conveying surface from sliding friction to rolling friction or low-resistance sliding, significantly reducing the coefficient of friction. Supported by the support plate 3011, the conveyor line 3012 maintains stable operation, guiding the pickled mustard tuber along a preset trajectory towards the storage box 303 until it falls into the storage box 303 to complete the collection process.

[0042] The storage box 303 includes a storage box body 3031 and a second moving wheel 3032, which is rotatably disposed below the storage box body 3031.

[0043] When it is necessary to replace the storage box 303, the operator pushes the storage box body 3031 filled with pickled vegetables. At this time, the second moving wheel 3032 located under the storage box body 3031 rotates, causing the entire storage box body 3031 to shift relative to the ground or placement plate 302, moving the full box out of the work area. Subsequently, the empty storage box body 3031 is pushed back onto the placement plate 302 in the opposite direction, completing the preparation for a new round of collection. During this process, the rotational characteristics of the second moving wheel 3032 make the movement of the storage box body 3031 smooth and effortless, avoiding wear or difficulties caused by direct dragging, and ensuring the continuity of the pool-opening operation.

[0044] Through the above technical solution, this application realizes that the storage box 303, which was originally bulky and difficult to move, has the ability to move autonomously because a second moving wheel 3032 is set under the storage box body 3031. This solves the problem of difficulty in replacing traditional fixed or wheelless storage boxes after they are fully loaded and the labor cost is high. It achieves the technical effects of reducing the labor intensity of workers, improving the efficiency of box replacement and supporting continuous operation.

[0045] The second embodiment of this application also provides a method for removing pickled mustard tubers from the pool, which is performed using any of the pickled mustard tuber removal devices described in the foregoing embodiments.

[0046] Step 1: Move the pickled mustard tuber removal device to the fermentation tank operating area; use the device's moving component 1 to position the entire equipment next to the fermentation tank to be processed. Specifically, the operator or the automatic guidance system drives the first moving wheel 102 at the bottom of the base 101 to rotate, moving the device on the ground. When it is necessary to adapt to different widths of the working passage or adjust the support span, the extension rod 1012 can be pulled to slide relative to the base body 1011, thereby changing the overall length of the base 101. The first moving wheel 102 moves synchronously with the extension rod 1012 to provide support. Through this telescopic base 101 structure and the cooperation of the moving wheel, the footprint and stability of the device can be flexibly adjusted, ensuring that the device can smoothly reach the designated position even in narrow fermentation workshops. This step provides the necessary space for subsequent material removal operations.

[0047] Step 2: Control the gripper structure 207 to grab the pickled mustard tuber inside the fermentation tank; The material is secured by the gripper structure 207 in the material handling assembly 2. Specifically, the control cylinder 2071 is activated and outputs thrust, causing the push ring 2072 to slide on the outside of the housing 2041. The movement of the push ring 2072 transmits power through multiple control rods 2073, driving multiple rotating claws 2074 to rotate around their axes, thereby causing the rotating claws 2074 to move closer together or open. When the rotating claws 2074 are closed, the buffer strips 20743 on the claw body 20741 contact the pickled mustard tuber or its container, providing a flexible gripping force to prevent damage to the material. At the same time, the leakage holes 20742 on the claw body 20741 allow the fermentation liquid to flow out, reducing the weight of the gripping. For example, when gripping a filter basket full of pickled mustard tuber, the control cylinder 2071 extends by 50mm, causing the push ring 2072 to move downward, and the four rotating claws 2074 tighten inward through the linkage mechanism, firmly clamping the edge of the filter basket. By controlling the linkage between cylinder 2071, push ring 2072 and control rod 2073, adaptive gripping of materials of different sizes is achieved, and the design of buffer strip 20743 and leakage hole 20742 effectively avoids the problems of material breakage and excessive liquid accumulation.

[0048] Step 3: Drive the lifting cylinder 201 to raise the rotating box 204 to the preset height, and make the gear 205 mesh with the rack 206 to drive the rotating box 204 to rotate; The lifting and tilting mechanisms are used to lift the grabbed material to the unloading position and tilt it. Specifically, the lifting cylinder 201 is fixed on the support frame 103, and its output end is connected to the lifting plate 202, which drives the entire rotating box 204 and the gripper structure 207 below to rise vertically. During the lifting process, if the gear 205 does not contact the rack 206, the counterweight block 2042 fixed on the box 2041 uses gravity to keep the box 2041 in a vertical state, preventing the material from accidentally slipping during the lifting process. When the lifting plate 202 rises to the preset height, the gear 205 fixed on the rotating box 204 meshes with the rack 206 fixed on one side of the support frame 103; as the lifting action continues or a special rotation drive is applied, the gear 205 rolls or moves relative to the rack 206, forcibly driving the rotating box 204 to tilt around the rotation axis 203. For example, with the preset height set at 1.5 meters above the ground, gear 205 just enters the meshing area of ​​rack 206, and the rotating box 204 rotates from 90 degrees to 135 degrees under the transmission of gear 205 and rack 206. Through the synergy of the steady-state holding function of counterweight 2042 and the forced rotation function of gear 205 and rack 206, both the safety of the lifting process and the automatic unloading at a precise angle are ensured.

[0049] Step 4: Collect the poured-out pickled mustard tubers through storage component 3; use storage component 3 to receive and temporarily store the material poured out from rotating box 204. Specifically, the turned pickled mustard tubers fall into conveyor 301 fixed to one side of support frame 103. Conveyor 301 includes support plate 3011 and conveyor line 3012 rotatably mounted on support plate 3011. After the conveyor line 3012 starts, it transports the pickled mustard tubers forward. The pickled mustard tubers at the end of the transport fall into storage box 303 placed on placement plate 302. The bottom of storage box 303 is provided with second moving wheels 3032, which facilitates quick pushing away and replacement of a new empty box after it is full. For example, the conveyor line 3012 uses belt drive with a speed of 0.2m / s to smoothly feed the pickled mustard tubers into the storage box body 3031 with a capacity of 50kg. By combining the continuous transmission function of the conveyor 301 with the quick replacement function of the pulley storage box 303, continuous operation of the unloading process is achieved, avoiding manual handling and intermediate accumulation, and significantly improving the efficiency of pool opening.

[0050] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
