Description

Technical Field

[0001] This invention relates to the field of brewing technology, and more particularly to a vat-digging device. Background Technology

[0002] The essence of winemaking lies in the skillful use of microbial communities to transform sugar- or starch-rich raw materials into flavorful beverages containing a specific concentration of alcohol through fermentation. Among China's rich and diverse wine culture, the brewing process of baijiu (white liquor) is particularly unique and complex, constituting a complete and rigorous system engineering project.

[0003] The entire production process of baijiu typically begins with the careful selection of raw materials, followed by the crucial koji-making stage, which cultivates a powerful microbial community for subsequent fermentation. Next comes the core step in the brewing process—fermentation. In this stage, the materials are placed in specific fermentation vessels. The sugars generated during koji-making and saccharification are efficiently converted into ethanol (alcohol) and trace flavor compounds such as alcohols, acids, esters, and aldehydes—all essential for the typical style of baijiu—through the metabolism of microorganisms. After fermentation, the liquor undergoes distillation, aging, blending, and flavoring before finally being bottled and shipped.

[0004] In traditional strong-aroma baijiu production, fermentation takes place in underground pits known as "mud pits." After a fermentation cycle is complete, the fermented mash (i.e., the raw material) needs to be dug out of the pits and sent to the next distillation process. Existing pit-digging equipment has a low degree of automation, resulting in low operational efficiency. Summary of the Invention

[0039] like Figures 4 to 6As shown, the digging equipment includes a guide rail device 60, a frame device 70, a digging bucket moving device 80, a rotating device 90, a first digging bucket device 100, and a second digging bucket device 110. The guide rail device 60 includes two parallel and spaced-apart first guide rails 61, as shown in the figure. Figure 4 As shown, two first guide rails 61 are arranged parallel and spaced apart in the vertical direction, and the first guide rails 61 extend in the horizontal direction. A truss device 70 is mounted on the first guide rails 61, and a hopper moving device 80 is mounted on the truss device 70. The truss device 70 is used to drive the hopper moving device 80 to move along the length direction of the first guide rails 61. A rotating device 90 is mounted on the hopper moving device 80, and the hopper moving device 80 is used to drive the rotating device 90 to move along the width direction of the first guide rails 61.

[0040] The first hopper device 100 and the second hopper device 110 are both mounted on the rotating device 90. The second hopper device 110 is used to scoop up the material in the upper part of the cylinder, and the first hopper device 100 is used to scoop up the remaining material in the cylinder. The rotating device 90 is used to drive the first hopper device 100 and the second hopper device 110 to rotate, so that the first hopper device 100 and the second hopper device 110 alternately rotate to the scooping position above the cylinder.

[0041] The cylinder digging equipment provided by this invention drives the digging bucket moving device 80 to move along the length direction of the first guide rail 61 via the gantry device 70, and drives the rotating device 90 to move along the width direction of the first guide rail 61 via the digging bucket moving device 80. This enables the free movement of the first digging bucket device 100 and the second digging bucket device 110 in the horizontal direction (XY two-dimensional plane), ensuring that the digging bucket can flexibly and accurately cover the entire working area above the cylinder opening. The rotating device 90 drives the first digging bucket device 100 and the second digging bucket device 110 to rotate, so that the first digging bucket device 100 and the second digging bucket device 110 alternately rotate to the digging position above the cylinder body. This realizes the function switching for different digging stages, and the optimal digging bucket can be used for operation without changing equipment, improving the adaptability and thoroughness of digging. The first digging bucket device 100 and the second digging bucket device 110 automatically switch between the digging position and the unloading position, so that the digging and unloading actions can be closely connected, greatly shortening the cycle of a single operation and effectively improving the overall operation efficiency.

[0042] In one embodiment of the present invention, such as Figure 7 and Figure 8As shown, the gantry device 70 includes a gantry body 71 and two first drive components. The gantry body 71 is arranged along the width direction of the first guide rail 61, thereby constructing a stable moving platform spanning the entire working area. The two first drive components are respectively arranged at both ends of the gantry body 71. This bilateral synchronous drive layout ensures that the gantry body 71 is subjected to balanced force during movement, effectively preventing equipment deviation or jamming that may be caused by unilateral drive, thereby ensuring the smoothness and synchronization accuracy of operation. The two first drive components are in one-to-one contact with the two first guide rails 61. The function of the first drive components is to drive the gantry body 71 to move along the length direction of the first guide rail 61.

[0043] In one embodiment of the present invention, such as Figure 7 and Figure 8 As shown, the first drive assembly includes a first drive motor 72 and a first drive wheel 73. The housing of the first drive motor 72 is bolted to the frame body 71. The first drive wheel 73 is connected to the shaft of the first drive motor 72 and contacts the corresponding first guide rail 61, realizing the direct output of driving torque. The rotational motion of the motor is efficiently converted into linear driving force through the friction between the drive wheel and the guide rail. When the first drive motor 72 drives the first drive wheel 73 to rotate, the first drive wheel 73 drives the frame body 71 to move along the length direction of the first guide rail 61 by relying on the friction between the first drive wheel and the guide rail. This achieves smooth and continuous longitudinal displacement control of the entire frame device 70. The entire drive process is responsive and simple to control.

[0044] In one embodiment of the present invention, such as Figure 7 and Figure 8 As shown, the main body 71 of the gantry includes two second guide rails and two connecting frames 76. The two second guide rails are arranged parallel to and spaced apart along the length of the first guide rail 61 and extend along the width of the first guide rail 61. The second guide rails are perpendicular to the first guide rail 61, providing a precise guiding reference for the lateral movement of the subsequent bucket moving device 80. A first track plate 74 is provided on the upper part of the second guide rail, and a second track plate 75 is provided on the lower part of the second guide rail. Both extend horizontally along the width of the first guide rail 61. Through this layered track design, the bucket moving device 80 and the bucket conveying device 120 are cleverly provided with their own independent running paths, so that equipment with different functions can move on the same gantry without interfering with each other, greatly improving space utilization and overall operational efficiency. Preferably, the second guide rails are I-beams. Utilizing the excellent cross-sectional characteristics of I-beams, they achieve extremely high bending strength with a relatively light weight, effectively supporting the weight of the bucket and materials, and ensuring structural stability and safety over long spans.

[0045] One connecting frame 76 is bolted to the first end of the two second guide rails, and the other connecting frame 76 is bolted to the second end of the two second guide rails, together forming a rectangular frame. Two first drive motors 72 are fixedly mounted on the two connecting frames 76 one-to-one and connected by bolts, so that the power source is directly arranged on the connecting frame 76 closest to the main guide rail, shortening the transmission chain and making the transmission of driving force more direct and efficient.

[0046] In one embodiment of the present invention, such as Figure 8 and Figure 9 As shown, the hopper moving device 80 includes a moving frame 81 and a second drive motor 84. The moving frame 81 is a rectangular frame. Two first limiting roller 82 assemblies are provided on both sides of the moving frame 81. Of course, the number of first limiting roller 82 assemblies is not limited to this. One, three or more first limiting roller 82 assemblies can also be provided on each side of the moving frame 81.

[0047] The first limiting roller assembly 82 includes a first limiting roller 82 and a second limiting roller 83. The first limiting roller 82 and the second limiting roller 83, positioned vertically, cooperate to clamp the track plate, providing a basis for subsequent precise positioning. Four connecting shafts are provided on both sides of the movable frame 81. Specifically, on the same side of the movable frame 81, two connecting shafts are located above the first track plate 74 and are spaced apart along the length of the first track plate 74. The two first limiting rollers 82 are rotatably engaged with the two connecting shafts above the first track plate 74. The remaining two connecting shafts are located below the first track plate 74 and are spaced apart along the length of the first track plate 74. The two second limiting rollers 83 are rotatably engaged with the two connecting shafts below the first track plate 74. The first limiting roller 82 and the second limiting roller 83 are respectively arranged above and below the first track plate 74 and spaced apart along its length. This layout of multiple support points on both sides of the track and along the direction of movement greatly enhances the running stability of the mobile frame 81, effectively preventing it from tipping over or swaying left and right when moving or carrying load, and ensuring smooth movement and stable posture.

[0048] The first limiting roller 82 rolls with the upper surface of the first track plate 74, and the second limiting roller 83 rolls with the lower surface of the first track plate 74, realizing rolling friction instead of sliding friction, significantly reducing movement resistance, energy consumption and wear; through the upper and lower cooperation of the first limiting roller 82 and the second limiting roller 83, the moving frame 81 can be bidirectionally limited in the vertical direction. The upper roller 42 can bear the weight of the moving frame 81 and the device above it, and the lower roller 42 can offset the upward reaction force or equipment vibration that may be generated during digging, thereby ensuring that the moving frame 81 is firmly constrained on the horizontal track and can only move along the length of the second guide rail.

[0049] The second drive motor 84 is mounted on the movable frame 81 and connected to it by bolts. A first gear 85 is sleeved on the shaft of the second drive motor 84. A first rack 86 is provided on the lower surface of one of the first track plates 74; alternatively, first racks 86 can be provided on the lower surfaces of both first track plates 74. The first rack 86 is connected to the first track plate 74 by screws and extends along the length of the second guide rail. The first gear 85 meshes with the first rack 86. When the second drive motor 84 drives the first gear 85 to rotate, the meshing action of the first gear 85 and the first rack 86 moves the movable frame 81 along the length of the second guide rail, achieving precise lateral movement of the hopper device.

[0050] In one embodiment of the present invention, such as Figure 8 and Figure 9 As shown, lateral limiting rollers 42 are provided on both sides of the movable frame 81. The lateral limiting rollers 42 are rotatably engaged with the movable frame 81, and the lateral limiting rollers 42 are rolledly engaged with the side of the two first track plates 74 that are close to each other, so as to limit the movable frame 81 in the length direction of the first guide rail 61.

[0051] In one embodiment of the present invention, such as Figures 8 to 10 As shown, a rotating hole is provided in the middle of the movable frame 81. The rotating hole is a circular through hole. An internal gear ring gear 87 is provided on the edge of the rotating hole. The upper surface of the internal gear ring gear 87 is an annular plane. The internal gear ring gear 87 is fixedly connected to the movable frame 81, which can be welded or bolted.

[0052] The rotating device 90 includes a turntable 91, a drive assembly, and a second gear 94. The turntable 91 is a circular disc and is rotatably mounted above the rotating hole, providing a stable and freely rotating bearing reference for the installation of the first hopper device 100 and the second hopper device 110. The turntable 91 is provided with rotating rollers 92, which roll in contact with the upper surface of the internal gear ring 87. Rolling friction replaces sliding friction, effectively reducing the frictional resistance of the turntable 91 during rotation, making the rotation smoother and reducing energy consumption. Similarly, the lower part of the internal gear ring 87 is also provided with rotating rollers 92, which rotate in contact with the turntable 91 and roll in contact with the lower surface of the internal gear ring 87. By providing rotating rollers 92 on both the upper and lower sides of the internal gear ring 87, the turntable 91 can be limited in the vertical direction, thereby forming a stable clamping structure and preventing the turntable 91 from overturning or moving up and down when subjected to unbalanced torque, significantly improving the operational stability of the rotating mechanism.

[0053] The turntable 91 is rotatably provided with a plurality of first circumferential limiting rollers 93. The plurality of first circumferential limiting rollers 93 are arranged at equal intervals along the circumference. The first circumferential limiting rollers 93 roll in cooperation with the outer side of the internal gear ring 87. The plurality of first circumferential limiting rollers 93 can limit the turntable 91 in the radial direction, ensuring that the turntable 91 always stays at the predetermined rotation center, avoiding gear meshing failure or jamming due to radial offset, and ensuring the durability of rotational accuracy.

[0054] The drive assembly is located on the turntable 91. The second gear 94 meshes with the internal gear ring gear 87 and is connected to the drive assembly. Through the meshing transmission of the second gear 94, a large torque output can be provided, ensuring the reliability of the drive under heavy load conditions. When the drive assembly drives the second gear 94 to rotate, the turntable 91 rotates horizontally under the cooperation of the second gear 94 and the internal gear ring gear 87, thereby driving the first digging bucket device 100 and the second digging bucket device 110 to rotate, realizing the change of position of the first digging bucket device 100 and the second digging bucket device 110, thus efficiently completing the automatic switching between the digging position and the unloading position, improving the overall operating efficiency of the cylinder digging equipment.

[0055] In one embodiment of the present invention, such as Figures 8 to 10 As shown, the drive assembly includes a third drive motor 95 and a steering reducer 96. The third drive motor 95 is mounted on the turntable 91; alternatively, the housing of the third drive motor 95 can be fixedly connected to the housing of the steering reducer 96. Two second gears 94 are provided, and they are horizontally positioned. The two second gears 94 are symmetrically arranged about the central axis of the turntable 91. This symmetrical arrangement ensures that the turntable 91 experiences balanced forces on both sides during rotation, effectively avoiding the eccentric torque caused by unilateral drive. This guarantees the smoothness of the turntable 91's rotation and the accuracy of its positioning, and significantly reduces wear on the central support structure of the turntable 91, extending its service life. The steering reducer 96 is mounted on the turntable 91, and its input shaft is connected to the shaft of the third drive motor 95. The steering reducer 96 has two output shafts, which are connected to the corresponding second gears 94. This allows the two symmetrically arranged second gears 94 to be driven synchronously, ensuring that the driving force on both sides of the turntable 91 is equal in magnitude and phase. This results in a smooth and powerful torque output, which drives the turntable 91 to complete a precise rotation.

[0056] In one embodiment of the present invention, such as Figure 11 As shown, the first hopper device 100 includes a first lifting assembly 101 and a first hopper. The first lifting assembly 101 is connected to the turntable 91, and the first hopper is connected to the first lifting assembly 101. The first lifting assembly 101 is used to drive the first hopper to move up and down.

[0057] The second hopper device 110 includes: a second lifting assembly 111 and a second hopper. The second lifting assembly 111 is connected to the turntable 91, and the second hopper is connected to the second lifting assembly 111. The second lifting assembly 111 is used to drive the second hopper to move up and down.

[0058] The first hopper device 100 includes a first lifting assembly 101 and a first hopper. The first lifting assembly 101 is connected to the turntable 91, and the first hopper is connected to the first lifting assembly 101. The first lifting assembly 101 is used to drive the first hopper to move up and down, so as to accurately control the digging depth and lifting height of the hopper according to the process requirements, realize the effective digging and transfer of materials deep in the pit, and ensure the automation and controllability of the digging operation.

[0059] The second digging bucket device 110 includes a second lifting assembly 111 and a second digging bucket. The second lifting assembly 111 is connected to the turntable 91, and the second digging bucket is connected to the second lifting assembly 111. The second lifting assembly 111 is used to drive the second digging bucket to move up and down. By independently controlling the second lifting assembly 111, the second digging bucket can operate at a different height than the first digging bucket, realizing the possibility of layered and zoned operations, which greatly improves the precision of digging and the overall efficiency.

[0060] In one embodiment of the present invention, such as Figure 4 , Figure 14 and Figure 15 As shown, the cylinder digging equipment also includes a hopper transport device 120, which is located below the mobile frame 81. This layout makes full use of the idle space below the equipment, realizing layered operations of digging and transporting materials in the vertical space without interference, thereby improving the overall efficiency of the equipment's operation process.

[0061] The hopper conveying device 120 includes a conveying trolley 130, a hopper assembly 140, and a gate assembly 150. The conveying trolley 130 includes a suspension 131 and a fourth drive motor 132 mounted on the suspension 131. The drive motor is directly integrated on the suspension 131, forming a self-driven power unit, which makes the energy transfer efficiency high. Two second limiting roller assemblies 83 are provided on both sides of the upper part of the suspension 131. The four second limiting roller assemblies 83 are arranged symmetrically in pairs. The second limiting roller assemblies 83 include a third limiting roller 133 and a fourth limiting roller 134. The third limiting roller 133 and the fourth limiting roller 134 are both rotatably engaged with the suspension 131. The third limiting roller 133 is rolled in engagement with one side of the upper surface of the second track plate 75, and the fourth limiting roller 134 is rolled in engagement with the other side of the upper surface of the second track plate 75. The third limiting roller 133 and the fourth limiting roller 134 are symmetrically arranged about the second track. This double-sided symmetrical roller limiting method firmly constrains the suspension 131 to the track, greatly enhances the lateral stability of the transport trolley 130 during operation, and effectively prevents the risk of swaying or derailment when it is running at high speed or under uneven load.

[0062] A second rack 135 is provided on the lower surface of the second track plate 75, extending along the length of the second track. A third gear 136 is sleeved on the shaft of the fourth drive motor 132, meshing with the second rack 135. When the fourth drive motor 132 drives the third gear 136 to rotate, the transport trolley 130 moves along the length of the second track under the cooperation of the third gear 136 and the second rack 135, realizing the efficient conversion of the motor's rotational motion into the trolley's linear translational motion, providing reliable and powerful power for long-distance horizontal material transport. The hopper assembly 140 is detachably connected to the suspension 131, facilitating the disassembly and installation of the hopper and greatly reducing downtime for maintenance. A discharge port is provided at the bottom of the hopper assembly 140, and a gate assembly 150 is connected to the hopper assembly 140, used to control the opening and closing of the discharge port.

[0063] In one embodiment of the present invention, such as Figure 4 , Figure 14 and Figure 15As shown, the gate assembly 150 is rotatably coupled to the hopper assembly 140 via a rotating shaft. A fourth gear 141 is mounted on the rotating shaft. A third rack 142 is mounted on the upper part of the hopper assembly 140. The third rack 142 is horizontally positioned and slidably coupled to the hopper assembly 140. The fourth gear 141 meshes with the third rack 142. A fifth drive motor 143 and a screw jack 144 are mounted on the lower part of the suspension 131. The shaft of the fifth drive motor 143 is connected to the input shaft of the screw jack 144. The output shaft of the screw jack 144 is positioned opposite to the end of the third rack 142. When the fifth drive motor 143 rotates in the forward direction, it drives the input shaft of the screw jack 144 to rotate. The output shaft of the screw jack 144 extends and contacts the end of the third rack 142, thereby pushing the third rack 142 to slide horizontally. The third rack 142 drives the gate assembly 150 to rotate through the fourth gear 141, thus opening the discharge port. When the fifth drive motor 143 rotates in the reverse direction, the output shaft of the screw jack 144 retracts and separates from the end of the third rack 142. The gate assembly 150 rotates under the action of gravity and returns to its initial position to close the discharge port.

[0064] In one embodiment of the present invention, the hopper assembly 140 is provided with a positioning post, which faces downwards. This arrangement utilizes the weight of the hopper assembly 140 itself as the locking force, resulting in a simple structure that eliminates the need for an additional locking mechanism, thus ensuring the reliability and safety of the connection. The suspension 131 is provided with a positioning hole, the opening of which faces upwards. The positioning post is inserted into the positioning hole. This insertion method not only achieves reliable load-bearing in the vertical direction but also provides precise positioning constraints in the horizontal plane, effectively preventing the hopper from shaking or shifting during the operation of the transport trolley 130, ensuring a smooth and safe transportation process. When it is necessary to separate the suspension 131 from the hopper assembly 140, simply use other equipment to lift the hopper assembly 140 from the bottom upwards a certain distance, causing the positioning post to separate from the positioning hole. Then, control the fourth drive motor 132 to rotate, causing the suspension 131 to move a certain distance horizontally, ensuring that the suspension 131 and the hopper assembly 140 are horizontally offset. The entire separation process is simple and logical, requiring only two basic actions: "vertical lifting" and "horizontal movement." This simplifies the automation control process and reduces its complexity, enabling rapid and efficient replacement and maintenance of the hopper assembly 140. Alternatively, positioning posts can be installed on the suspension 131 and positioning holes on the hopper assembly 140, achieving the same effect.

[0065] In one embodiment of the present invention, the first hopper includes a hopper body 10, two first gripping blades 20, and a first linear drive assembly 30. The hopper body 10 includes an upper cylinder 11 and multiple arc-shaped gripping plates 12. The upper cylinder 11 is a circular cylinder. In this embodiment, the sidewall of the upper cylinder 11 is composed of multiple plates arranged sequentially along the circumference, and the upper ends of the multiple plates are connected to the top wall of the upper cylinder 11. Of course, the sidewall of the upper cylinder 11 can also be composed of a single circular plate. The bottom of the upper cylinder 11 has a lower port, which is a circular opening.

[0066] Each arc-shaped gripping piece 12 is designed to have equal width and height. Multiple arc-shaped gripping pieces 12 are arranged circumferentially to form a variable-diameter cylinder with a feed inlet at the bottom. A small gap is reserved between adjacent arc-shaped gripping pieces 12, providing necessary space for the radial swing of each gripping piece. This effectively ensures that adjacent gripping pieces do not collide or interfere with each other during contraction, guaranteeing the smooth operation of the variable-diameter function. The upper end of each arc-shaped gripping piece 12 is hinged to the upper cylinder 11 via a hinge, allowing each gripping piece to swing precisely radially around its axis. The hinge is located on the inner side of the arc-shaped gripping piece 12 to protect it from external scratches and collisions, effectively protecting critical moving parts and extending their service life. It also makes the outer wall of the variable-diameter cylinder smoother, facilitating its sliding against the inner wall of the cylinder. The upper cylinder 11 and the variable-diameter cylinder work together to form a complete storage chamber.

[0067] The first gripping blade 20 is a semi-circular plate. When the two blades are closed, they can be joined to form a complete circular disc, thus sealing the circular feed inlet without gaps and effectively preventing the excavated material from spilling during lifting and transfer. The two first gripping blades 20 are symmetrically arranged at the feed inlet, ensuring the mechanical balance and motion coordination of the opening and closing action, and making the force on the drive mechanism more even. The side of the two first gripping blades 20 that is close to each other is rotatably connected to the first pin 21. This structure is simple and reliable, and can achieve a large angle of opening and closing around the common pin. It can provide a large opening for unobstructed material entry and provide a strong closing force to ensure reliable closure of the feed inlet.

[0068] The first linear drive assembly 30 is connected to the first gripping blade 20 and the upper cylinder 11. The first linear drive assembly 30 is used to drive the first gripping blade 20 to switch between a folded state and an unfolded state. In the folded state, the two first gripping blades 20 are in a vertical state and both first gripping blades 20 are located below the first pin 21, and the feed inlet is in an open state. In the unfolded state, the two first gripping blades 20 are in a horizontal state to block the feed inlet.

[0069] The hopper provided by this invention arranges multiple arc-shaped gripping plates 12 sequentially along the circumference to form a variable-diameter cylinder with a feed inlet at the bottom. The upper end of each arc-shaped gripping plate 12 is hinged to the upper cylinder 11, enabling each arc-shaped gripping plate 12 to move freely in the radial direction of the variable-diameter cylinder, providing a structural basis for the adaptive deformation of the hopper. When the hopper enters the cylinder to dig up material at the bottom, the lower end of the arc-shaped gripping plate 12 contacts the inner wall of the cylinder with its rounded transition. Under the guidance and compression of the inner wall of the cylinder, each arc-shaped gripping plate 12 can synchronously contract inward along the radial direction of the variable-diameter cylinder, thereby reducing the outer diameter of the variable-diameter cylinder in real time to accurately fit the arc shape of the bottom corner of the cylinder, solving the problem that traditional hoppers cannot fit the corner of the cylinder due to their fixed shape. This adaptive fit ensures that the material located at the junction of the cylinder sidewall and the cylinder bottomwall is effectively scraped up and completely enters the storage chamber. Ultimately, it ensures that the hopper can remove all the remaining material in the bottom area of ​​the cylinder, avoiding material residue and significantly improving the efficiency and thoroughness of material removal in a single operation.

[0070] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the first linear drive assembly 30 includes a first electric cylinder 31 and two first arc-shaped connecting rods 32. The first electric cylinder 31 is vertically arranged on the upper part of the upper cylinder 11. The cylinder body of the first electric cylinder 31 is connected to the top wall of the upper cylinder 11 by bolts. A through hole is provided in the center of the top wall of the upper cylinder 11, and the telescopic rod of the first electric cylinder 31 passes through the through hole.

[0071] Two first arc-shaped connecting rods 32 are disposed within the storage cavity, and these two connecting rods 40 are symmetrically arranged about the extension line of the central axis of the telescopic rod. This symmetrical structural layout ensures the force balance of the mechanism during movement, effectively counteracts lateral forces, and guarantees the smoothness of transmission. Simultaneously, the centers of the two first arc-shaped connecting rods 32 are located on the side of the first arc-shaped rod facing its extension line, allowing the connecting rods 40 to avoid the first gripping blade 20 and the first pin 21 during retraction, thus improving space utilization. The upper ends of both first arc-shaped connecting rods 32 are hinged to the telescopic rod of the first electric cylinder 31 via pins, and the lower ends are respectively hinged to the upper surfaces of the two first gripping blades 20 via pins. The pin hinges construct a flexible and reliable connecting rod 40 transmission pair, which can efficiently convert linear motion into rotational motion.

[0072] The first electric cylinder 31 is used to switch between the extended and retracted states. In the extended state, the first electric cylinder 31 drives the connecting rod 40 downward, causing the two first gripping blades 20 to be in a vertical position. At this time, the two first arc-shaped connecting rods 32 are located on opposite sides of the two first gripping blades 20. The two first arc-shaped connecting rods 32 push the two first gripping blades 20 closer together and ensure that the feed inlet is in its maximum open state, thereby maximizing the cross-sectional area of ​​the feed channel, reducing the resistance to material entry, and improving loading efficiency. In the retracted state, the first electric cylinder 31 drives the connecting rod 40 upward, pulling the two first gripping blades 20 back to a horizontal state. At this time, the two first arc-shaped connecting rods 32 are located above the two first gripping blades 20. The two first gripping blades 20 are spliced ​​together to form a circular plate that seals the feed inlet, achieving complete sealing of the bottom and effectively preventing material spillage during lifting or transportation, ensuring the cleanliness of the operation.

[0073] In one embodiment of the present invention, such as Figure 1 As shown, the first linear drive assembly 30 also includes a pusher plate 33, which is a circular plate with a diameter smaller than the inner diameter of the upper cylinder 11. The pusher plate 33 is horizontally positioned inside the storage cavity and is connected to the telescopic rod of the first electric cylinder 31. The first electric cylinder 31 is also used to drive the pusher plate 33 to move up and down. When the first electric cylinder 31 is in the retracted state, the pusher plate 33 is above the storage cavity, thereby emptying the main volume space of the storage cavity to ensure that the hopper can hold a sufficient amount of material during the digging process, thus ensuring the loading efficiency of a single digging. When the first electric cylinder 31 is in the extended state, the pusher plate 33 moves downward to push the material in the storage cavity out of the feed inlet. The material is discharged by physical pushing, which can effectively overcome the adhesion between wet or sticky materials (such as distiller's grains) and the cylinder wall, and prevent material residue in the storage cavity.

[0074] In one embodiment of the present invention, a connecting post 34 is provided at the bottom of the pusher plate 33, and the connecting post 34 is located at the center of the bottom of the pusher plate 33. The upper ends of the two first arc-shaped connecting rods 32 are hinged to the connecting post 34. Of course, the connection method of the first arc-shaped connecting rods 32 is not limited to this. Alternatively, a through hole can be provided at the center of the pusher plate 33, and the telescopic rod of the first electric cylinder 31 can be passed through the through hole and then hinged to the upper ends of the two first arc-shaped connecting rods 32.

[0075] In one embodiment of the present invention, such as Figure 1 and Figure 2As shown, the hopper also includes multiple connecting rods 40, which are circumferentially spaced within the storage cavity. The distance between adjacent connecting rods 40 is equal, and the positions of the connecting rods 40 correspond one-to-one with the positions of the arc-shaped gripping plates 12. The lower end of each connecting rod 40 has a first bending portion 43, which bends towards the side of the connecting rod 40 near the side wall of the upper cylinder 11. By providing the outward bending portion 43, the force-bearing end of the connecting rod 40 can avoid the movement trajectory of the upper component, ensuring that the connecting rod 40 does not interfere with the hinge at the upper end of the gripping plate during transmission. The first bending portion 43 of the connecting rod 40 is connected one-to-one with the arc-shaped gripping plates 12. The upper end of the connecting rod 40 is provided with a second bending part 44. The second bending part 44 bends towards the side of the connecting rod 40 away from the side wall of the upper cylinder 11. The second bending part 44 forms a force-bearing boss at the top of the connecting rod 40, which facilitates the contact and force application of the driving component. At the same time, it also provides reasonable space for the installation of the elastic reset component. The second bending part 44 of the connecting rod 40 is connected to the top wall of the upper cylinder 11 through a tension spring 41. By utilizing the elastic recoil force of the tension spring 41, the connecting rod 40 can automatically reset when it loses external driving force, thereby driving the arc-shaped gripping plate 12 to return to its initial open state, ensuring the reliability and stability of the device during repeated operations.

[0076] The pusher plate 33 has multiple downward-sloping inclined surfaces 35 along its edge. These inclined surfaces 35 slide against the side of the second bent portion 44 opposite to the side wall of the upper cylinder 11. The inclined surfaces 35 and the second bent portion 44 form a wedge-shaped transmission pair. Utilizing the guiding effect of the inclined surfaces 35, the vertical lifting motion of the pusher plate 33 can be converted into the horizontal radial motion of the upper end of the connecting rod 40, thus achieving a change in the direction of force. When the pusher plate 33 moves upward, it pushes the second bent portion 44 towards the side wall of the upper cylinder 11 via the inclined surfaces 35. This causes the tension spring 41 to be further stretched, while the first bent part 43 moves closer to the extension line of the central axis of the upper cylinder 11, causing the corresponding arc-shaped gripping piece 12 to rotate around the hinge point between itself and the upper cylinder 11, thereby reducing the outer diameter of the variable diameter cylinder and realizing the active shrinkage of the outer diameter of the hopper. This allows it to flexibly adapt to working areas of different diameters, especially to fit tightly into the arc-shaped corner at the bottom of the fermentation tank, ensuring thorough scraping and effectively solving the problem of incomplete material removal in dead corners of traditional equipment, thus significantly improving the digging efficiency.

[0077] In one embodiment of the present invention, a plurality of fixing seats 36 are provided on the edge of the upper surface of the pusher plate 33. The plurality of fixing seats 36 are arranged at equal intervals along the circumference. The fixing seats 36 are welded or bolted to the pusher plate 33. The inclined surface 35 is located on the side of the fixing seat 36 facing the side wall of the upper cylinder 11.

[0078] In one embodiment of the present invention, such as Figure 1 and Figure 2As shown, a roller 42 is provided at the upper end of the connecting rod 40, that is, the roller 42 is located at the second bend 44, and the roller 42 and the inclined surface 35 are in rolling contact. By setting the roller 42, the contact form between the connecting rod 40 and the driving inclined surface 35 is changed from traditional sliding friction to rolling friction, which greatly reduces the friction coefficient between the contact surfaces, thereby significantly reducing the resistance loss of the mechanism during operation and avoiding the problem of severe wear or jamming of parts caused by long-term dry friction.

[0079] In one embodiment of the present invention, such as Figure 3 As shown, multiple limiting blocks 13 are provided on the outer side of the lower port. The multiple limiting blocks 13 are arranged at equal intervals along the circumference and are vertically set. The position of the limiting blocks 13 corresponds one-to-one with the position of the arc-shaped clamping piece 12 to ensure that each arc-shaped clamping piece 12 can obtain independent limiting support, so that the entire variable diameter cylinder is evenly distributed when under force, avoiding structural deformation or asynchronous movement caused by the lack of local limiting. The upper end of the limiting block 13 is welded or riveted to the outer side of the upper cylinder 11, and the lower end of the limiting block 13 extends downward to ensure that even when the arc-shaped clamping piece 12 swings within a certain angle range, its upper end is always within the blocking stroke of the limiting block 13. In the extended state, the limiting block 13 engages with the outer side of the upper end of the arc-shaped gripping plate 12, thereby limiting the maximum outer diameter of the variable diameter cylinder and precisely defining the initial maximum outline size of the variable diameter cylinder. This prevents the arc-shaped gripping plate 12 from excessively flipping outward under the action of spring or gravity, avoiding situations where the hopper cannot be smoothly placed into the cylinder or the articulation mechanism is damaged due to excessive diameter, thus ensuring the safety and reliability of the equipment operation.

[0080] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the hopper also includes two fixed rods 50, which are vertically installed inside the storage chamber. The upper ends of both fixed rods 50 are connected to the upper cylinder 11, and the lower ends of the two fixed rods 50 are respectively rotatably engaged with the two ends of the first pin 21, providing two stable rotational fulcrums for the first pin 21, limiting the axial movement and radial displacement of the pin, and ensuring that the first gripping blade 20 connected to it has a precise trajectory during opening and closing, without jamming or deflection. The fixed rods 50 are used to provide support for the first pin 21, ensuring that the two first gripping blades 20 have a stronger material-bearing capacity. This allows the bottom closing mechanism to maintain extremely high structural stability when the hopper is gripping high-density or fully loaded materials, preventing bottom leakage or breakage failure caused by pin bending under stress, and significantly extending the service life of the equipment under high-load conditions.

[0081] In one embodiment of the present invention, such as Figures 11 to 13As shown, the first lifting assembly 101 includes a second electric cylinder, which is vertically mounted on the turntable 91. The cylinder body of the second electric cylinder is connected to the turntable 91 by bolts, and the telescopic rod of the second electric cylinder passes through the turntable 91 and connects to the top of the upper cylinder 11. Preferably, the cylinder body of the first electric cylinder 31 is located inside the telescopic rod of the second electric cylinder, which effectively improves the compactness of the first hopper device 100. When the first hopper is used for digging, the telescopic rod of the second electric cylinder extends, allowing the first hopper to insert into the cylinder body for digging. After digging, the telescopic rod of the second electric cylinder retracts, raising the height of the first hopper so that the first hopper leaves the cylinder body. By controlling the rotation of the third drive motor 95, the third drive motor 95 drives the second gear 94 to rotate. With the cooperation of the second gear 94 and the internal gear ring gear 87, the turntable 91 rotates in the horizontal direction, thereby driving the first digging bucket to rotate above the conveying bucket assembly 140. Then, the first electric cylinder 31 is controlled to extend, and the first electric cylinder 31 drives the first arc-shaped connecting rod 32 to press down, so that the two first grabbing blades 20 are in a vertical state, the feed port of the hopper body 10 is in an open state, and the material in the storage chamber enters the interior of the conveying bucket assembly 140 from the feed port.

[0082] In one embodiment of the present invention, such as Figures 11 to 13 As shown, the second hopper includes a barrel hopper 112, two second gripping blades 113, and a second linear drive assembly 114. The bottom of the barrel hopper 112 has a lower opening, which is a circular opening.

[0083] The second gripping blade 113 is a semi-circular plate. When the two second gripping blades 113 are closed, they can be spliced ​​together to form a complete circular disc, thereby sealing the circular lower opening and effectively preventing the excavated material from spilling during lifting and transfer. The two second gripping blades 113 are symmetrically arranged at the lower opening, and the side of the two second gripping blades 113 that is close to each other is rotatably connected to the second pin shaft, which is connected to the side wall of the drum hopper 112.

[0084] The second linear drive assembly 114 is connected to the second gripping blade 113 and the barrel hopper 112. The second linear drive assembly 114 is used to drive the second gripping blade 113 to switch between a folded state and an unfolded state. In the folded state, the two second gripping blades 113 are in a vertical state and both are located below the second pin shaft, with the lower opening in an open state. In the unfolded state, the two second gripping blades 113 are in a horizontal state to seal the lower opening.

[0085] In one embodiment of the present invention, such as Figures 11 to 13As shown, the second linear drive assembly 114 includes a third electric cylinder and two second arc-shaped connecting rods 115. The third electric cylinder is vertically arranged on the upper part of the barrel hopper 112. The cylinder body of the third electric cylinder is connected to the top wall of the barrel hopper 112 by bolts. A through hole is provided in the center of the top wall of the barrel hopper 112, and the telescopic rod of the third electric cylinder passes through the through hole.

[0086] Two second arc-shaped connecting rods 115 are disposed inside the barrel hopper 112, and the two second arc-shaped connecting rods 115 are arranged symmetrically about the extension line of the central axis of the telescopic rod. The centers of the two second arc-shaped connecting rods 115 are located on the side of the second arc-shaped connecting rod 115 facing the extension line. The upper ends of the two second arc-shaped connecting rods 115 are hinged to the telescopic rod of the third electric cylinder by pins, and the lower ends are respectively hinged to the upper surfaces of the two second gripping blades 113 by pins.

[0087] In one embodiment of the present invention, such as Figures 11 to 13 As shown, the second linear drive assembly 114 also includes a pusher disc 116. The pusher disc 116 is a circular plate with a diameter smaller than the inner diameter of the barrel hopper 112. The pusher disc 116 is horizontally positioned inside the barrel hopper 112. The pusher disc 116 is connected to the extension rod of the third electric cylinder, which also drives the pusher disc 116 to move up and down. When the third electric cylinder is in the retracted state, the pusher disc 116 is above the barrel hopper 112; when the third electric cylinder is in the extended state, the pusher disc 116 moves downward to push the material in the barrel hopper 112 out of the lower opening, preventing material residue in the barrel hopper 112.

[0088] In one embodiment of the present invention, a connecting post is provided at the bottom of the pusher disk 116, the connecting post is located at the center of the bottom of the pusher disk 116, and the upper ends of the two second arc-shaped connecting rods 115 are hinged to the connecting post.

[0089] In one embodiment of the present invention, such as Figure 11As shown, the second lifting assembly 111 includes a fourth electric cylinder, which is vertically mounted on the turntable 91. The cylinder body of the fourth electric cylinder is connected to the turntable 91 by bolts, and the telescopic rod of the fourth electric cylinder passes through the turntable 91 and connects to the top of the bucket hopper 112. Preferably, the cylinder body of the third electric cylinder is located inside the telescopic rod of the fourth electric cylinder. When the second hopper is used for digging, the telescopic rod of the fourth electric cylinder extends, causing the second hopper to insert into the cylinder body for digging. After digging, the telescopic rod of the fourth electric cylinder retracts, raising the height of the second hopper so that the second hopper leaves the cylinder body. By controlling the rotation of the third drive motor 95, the third drive motor 95 drives the second gear 94 to rotate. With the cooperation of the second gear 94 and the internal gear ring gear 87, the turntable 91 rotates in the horizontal direction, thereby driving the second hopper to rotate above the conveying hopper assembly 140. Then, the third electric cylinder extension rod is controlled to extend, and the third electric cylinder drives the second arc-shaped connecting rod 115 to press down, so that the two second gripping blades 113 are in a vertical state, and the lower opening of the barrel hopper 112 is in an open state. The material in the barrel hopper 112 enters the interior of the conveying hopper assembly 140 from the lower opening.
