Description

An adjustable-diameter silage bagging device Technical Field

[0001] This utility model relates to the field of silage filling, and more specifically to a silage bagging device with adjustable diameter. Background Technology

[0002] Silage is a method of preserving the nutritional value of feed by harvesting silage materials at an appropriate time, then chopping, compacting, and sealing them for storage. This method effectively maintains the nutritional components of the feed and extends its shelf life. Silage bags are containers used to store and preserve silage feed. They are typically made of multiple layers of plastic film, providing excellent barrier properties to effectively prevent air and moisture from entering the bag, thus providing favorable conditions for anaerobic fermentation during the silage process.

[0003] During the silage filling process, silage bags need to be fitted onto the discharge port of the silage filling machine. However, in actual production, customers select silage bags of different sizes, especially with significant differences in the diameter of the silage bags. The factory's silage filling machine fills silage bags with different diameters. When there is a large difference between the diameter of the silage filling machine and the diameter of the silage bag, it is difficult to accurately and securely fit the silage bag onto the silage filling machine, which can easily lead to loose connections and leakage.

[0004] Alternatively, CN222098099U discloses a forage silage baler that provides another filling method, in which silage flows out from the outlet of the buffer bin (equivalent to the outlet of the silage filling machine) and falls into the fixed bag column fitted with silage bags through the guide bucket. Although this structure can fit the silage bags into the fixed bag column that is adapted to its size, there is a problem that the silage spills during the filling process, thereby reducing the bagging efficiency and causing waste. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides an adjustable-diameter silage bagging device. By using isomorphic diameter adjustment devices at both ends of the elastic connecting pipe, and through the cooperation of a telescopic rod and a drive mechanism, the bag diameter can be quickly and accurately adjusted. This solves the installation difficulties and leakage problems caused by the mismatch between the silage bag and the filling machine diameter in the prior art, thereby improving filling efficiency and sealing performance.

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

[0007] An adjustable-diameter silage bagging device includes an elastic connecting pipe, with a first diameter adjustment device for connecting to a silage filling machine and a second diameter adjustment device for connecting to a silage bag at both ends of the elastic connecting pipe. The first diameter adjustment device and the second diameter adjustment device have the same structure.

[0008] The first regulating device includes a housing, a driving mechanism and several telescopic rods extending radially out of the housing. The outer end of the telescopic rod is connected to an elastic connecting tube, the rod body slides on a guide rail provided inside the housing, and the inner end of the telescopic rod is connected to the driving mechanism. The telescopic rod moves radially along the housing under the action of the driving mechanism.

[0009] The elastic connecting tube can be made of thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU) or modified polyethylene material, which has good elastic recovery performance and tear resistance, and can maintain a stable sealing state during multiple expansion and contraction deformations, adapting to the high compatibility connection requirements between silage filling machines and silage bags of different diameters.

[0010] Currently, during the silage filling process, the diameter of the silage bag and the discharge port of the filling machine are often inconsistent, making it difficult to accurately fit the silage bag. This often results in problems such as unstable installation, loose connection, and leakage of liquid. Traditional connection methods rely on fixed-size adapters, which lack flexible adjustment functions and cannot cope with changes in various bag types and equipment interface specifications, thus limiting the equipment's versatility and on-site adaptability.

[0011] Compared with the prior art, the adjustable silage bagging device described in this application overcomes the shortcomings of traditional fixed-size adapters that cannot flexibly match the discharge port of filling machines and the bag opening of silage bags of different specifications. By setting the same diameter adjustment device at both ends of the elastic connecting tube, combined with multiple radially distributed telescopic rods and their cooperating drive mechanism, the connection diameter can be dynamically adjusted, giving the bagging interface a high degree of versatility and compatibility. The telescopic rod drives the elastic connecting tube with flexible deformation capability, and its diameter expands or contracts during the telescopic process, which can effectively fit the contour of the filling machine and the silage bag to form a good circumferential sealing contact surface.

[0012] Preferably, the driving mechanism includes a rotating wheel supported in the middle of the housing, and a plurality of arc-shaped rails are provided on the rotating wheel. The protruding key provided at the inner end of the telescopic rod is slidably engaged in the arc-shaped rails. The rotating wheel rotates under the drive of the power mechanism, driving the plurality of telescopic rods to move synchronously along the radial direction of the housing.

[0013] Multiple telescopic rods are driven by a unified rotating wheel, enabling them to extend and retract synchronously along the radial direction of the housing. This ensures a stable and consistent adjustment process, improves the coordination and accuracy of the caliper adjustment, and requires only a small input force to drive multiple telescopic rods to move synchronously radially.

[0014] Preferably, there are at least three telescopic rods, which are evenly distributed along the circumference of the shell, and each telescopic rod has the same length;

[0015] This structural design ensures that multiple telescopic rods move synchronously and symmetrically in the radial direction under the action of the drive mechanism. This allows the diameter of the elastic connecting pipe to remain balanced during the adjustment process, which not only improves the stability and accuracy of the adjustment, but also enhances the tightness of the fit between the device and the silage filling machine and silage bags, effectively preventing leakage and further improving filling efficiency and sealing reliability.

[0016] Preferably, the outer end of the telescopic rod is provided with a circumferentially extending arc-shaped portion. The arc-shaped portion is made of a material with a certain degree of elasticity or flexibility, which can move synchronously with the telescopic rod during radial adjustment and deform accordingly according to the diameter of different connected objects, thereby making it fit more closely with the elastic connecting tube, improving the sealing and stability of the overall assembly, and avoiding leakage or slippage caused by poor contact. This structure not only enhances the adaptability of the bagging device, but also helps to improve the efficiency and reliability of on-site operations.

[0017] Preferably, the outer edge of the arc-shaped portion of the first diameter adjustment device is provided with a plurality of hooks, and one end of the elastic connecting tube is provided with a plurality of hanging holes, which are hung on the hooks;

[0018] The elastic connecting pipe is detachably connected to the first diameter adjustment device, so that when in use, the first diameter adjustment device can be fixed at the discharge port of the silage filling machine first, and then the elastic connecting pipe can be hung on the hook, which facilitates assembly and disassembly.

[0019] Preferably, the arc-shaped part of the first diameter adjustment device is magnetic; the magnetic arc-shaped part can be directly adsorbed onto the outer periphery of the discharge pipe of the silage filling machine, so that the diameter adjustment device can be quickly positioned and firmly fixed on the discharge pipe without additional fasteners, simplifying the installation steps and maintaining a stable fit during the filling process, further improving the installation convenience and sealing reliability at the interface.

[0020] Preferably, the inner edge of the arc-shaped part of the second diameter adjustment device is fixedly connected to the elastic connecting tube, and a plurality of pawls are provided on the outer edge of the arc-shaped part;

[0021] The outer edge of the arc-shaped part is equipped with several pawls for engaging the edge of the silage bag. This not only prevents the elastic connecting tube from slipping relative to the silage bag during material filling, but also allows the pawls to self-lock and maintain the clamping state after the diameter shrinks. This significantly improves the tensile strength and sealing reliability of the bag connection, avoiding the risk of the bag falling off or leaking.

[0022] Preferably, when the telescopic rod is retracted, the arc-shaped parts fit together sequentially in the circumferential direction to form a ring structure;

[0023] After the arc-shaped part is fitted into a ring, it can effectively protect the end of the telescopic rod from external impacts and debris intrusion, improve the durability and reliability of the device during storage and transportation, and also make the device more compact in the non-use state, making it easier to store and transport on site.

[0024] Preferably, the power mechanism includes a handwheel supported on the housing, the handwheel disc being located on the outside of the housing, and the handwheel axle being connected to a rotating gear;

[0025] When the operator rotates the handwheel, the input torque is transmitted to the rotating wheel via the axle and gears, causing the rotating wheel to drive the telescopic rod to move radially synchronously, thereby achieving precise adjustment of the caliber. This handwheel drive method is simple in structure, reliable and durable, and can complete the adjustment without an external power supply, which reduces maintenance and energy costs, and allows on-site personnel to quickly and intuitively adjust the caliber.

[0026] Preferably, the power mechanism includes a drive motor installed inside the housing, and the output gear of the drive motor is connected to the rotary gear;

[0027] Preferably, this invention integrates a drive motor within the housing, with its output gear directly meshing with the rotating gear to power the rotating wheel. This design not only embeds the power source within the housing, maintaining the overall compactness and sealing of the device, but also precisely controls the synchronous movement of the telescopic rod through the motor's rotational speed and torque, automating the diameter adjustment process and significantly improving adjustment efficiency and repeatability.

[0028] The beneficial effects of this utility model are as follows:

[0029] 1. High adaptability and versatility: By setting the same diameter adjustment device at both ends of the flexible connecting tube, a flexible connection between the filling machine outlet and the silage bag opening can be achieved, effectively solving the problems of loose connection, poor sealing and liquid leakage caused by mismatched diameters in the existing technology, and improving the versatility and on-site adaptability of the bagging device.

[0030] 2. The diameter is dynamically adjustable and easy to operate; multiple telescopic rods distributed radially along the shell work in conjunction with the drive mechanism to achieve synchronous telescopic movement. The connection diameter can be dynamically adjusted according to actual needs, and it has the advantages of high coordination, high precision and intuitive and simple operation in the adjustment process.

[0031] 3. Supports multiple driving methods to adapt to different application scenarios; the device can be manually driven by a handwheel or driven by a built-in motor, which can realize on-site adjustment with no electricity and simple structure, as well as support intelligent operation mode with automation and precise control, to meet the needs of different use environments and degrees of automation.

Detailed Implementation

[0037] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of this utility model and the features within them can be combined with each other.

[0038] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below. Example 1

[0039] Referring to Figure 1, an adjustable-diameter silage bagging device includes an elastic connecting pipe 1. The elastic connecting pipe 1 is preferably made of materials with good flexibility and wear resistance, such as thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), or modified polyethylene, which ensures the sealing performance of the connection part and has a certain resistance to deformation. The elastic connecting pipe 1 is provided with a first diameter adjustment device 21 for connecting to the silage filling machine 18 and a second diameter adjustment device 22 for connecting to the silage bag, respectively. The first diameter adjustment device 21 and the second diameter adjustment device 22 have the same structure, which facilitates uniform manufacturing and assembly.

[0040] The first caliber adjustment device 21 includes a housing 2, which is cylindrical in shape and made of high-strength metal or engineering plastic, providing good structural stability. Inside the housing 2 is a drive mechanism and several telescopic rods 6 extending radially out of the housing 2. The outer ends of the telescopic rods 6 are connected to elastic connecting pipes 1, and the rod bodies of the telescopic rods 6 slide on guide rails 4 provided inside the housing 2. The inner ends of the telescopic rods 6 are connected to the drive mechanism. Under the action of the drive mechanism, the telescopic rods 6 move radially along the housing 2. The drive mechanism can be a drive assembly composed of several cylinders, electric push rods, or hydraulic cylinders. Alternatively, an electric lead screw assembly with synchronous output function can be used. Using the aforementioned drive assembly to drive the telescopic rod 6 is existing technology and will not be elaborated further. The drive mechanism is installed in the middle of the housing 2 and is used to centrally drive multiple telescopic rods 6 to extend and retract synchronously. Radially extending guide rails 4 are evenly distributed on the inner wall of the housing 2 around the drive mechanism, cooperating with the drive mechanism and providing guidance and fixation, so that each telescopic rod 6 performs synchronous reciprocating motion in the radial direction, driving the openings at both ends of the elastic connecting pipe 1 to extend and retract, thereby adjusting the diameter of the entire device to adapt to the connection requirements of silage filling machines or silage bags of different diameters. Example 2

[0041] Based on the above embodiment 1, the driving mechanism includes a rotating wheel 9 supported in the middle of the housing 2. The rotation plane of the rotating wheel 9 is perpendicular to the axial direction of the housing 2. The rotating wheel 9 is rotatably supported in the housing 2 by bearings. The rotating wheel 9 is provided with several arc-shaped rails 10. The arc-shaped rails 10 are curved structures extending outward from the center of the rotating wheel 9. The form can be an arc-shaped groove or an arc-shaped hole penetrating the rotating wheel 9. The inner end of each telescopic rod 6 is provided with a protruding key 11 corresponding to the arc-shaped rail 10. The protruding key 11 is slidably embedded in the arc-shaped rail 10. When the rotating wheel 9 rotates in a predetermined direction under the drive of the power mechanism, the arc-shaped rail 10 drives the protruding key 11 embedded therein to move synchronously, thereby driving each telescopic rod 6 to move forward and backward along the radial direction of the housing 2. The power mechanism can be a handwheel or a motor.

[0042] To ensure the stability of the caliber adjustment, at least three telescopic rods 6 are used, preferably six, evenly distributed around the circumference of the housing 2, and each telescopic rod 6 has the same length. The coordinated movement of multiple telescopic rods achieves uniform adjustment of the interface, effectively avoiding problems such as interface misalignment, poor sealing, or material leakage caused by uneven adjustment. Example 3

[0043] Based on the above embodiment 1, referring to Figure 4, the outer end of the telescopic rod 6 is provided with a circumferentially extending arc-shaped part 7, and the arc-shaped part 7 should have a certain deformation capacity;

[0044] The outer edge of the arc-shaped part 7 of the first diameter adjustment device 21 is provided with several hooks 5 distributed at equal intervals. One end of the elastic connecting tube 1 is provided with a corresponding number and position of hanging holes. The hanging holes are securely attached by the hooks 5. This structure ensures a sealing and fixing effect while having good disassembly and ease of operation, making it easy to replace or maintain.

[0045] The arc-shaped part 7 of the first diameter adjustment device 21 is made of magnetic material or its surface is coated with magnetic material, thereby giving the arc-shaped part 7 a magnetic function, so that the first diameter adjustment device 21 can be adsorbed onto the outer peripheral surface of the discharge port pipe wall of the silage filling machine 18, achieving rapid positioning and stable fit under different diameter conditions; in order to further enhance the firmness and vibration resistance of the connection, it can be used in conjunction with external auxiliary fixing structures such as cable ties and clamps, so as to adapt to the working environment with frequent equipment vibration or complex working conditions;

[0046] The arc-shaped part 7 is preferably made of a material with a certain elasticity or flexibility, such as elastic rubber, thermoplastic elastomer or composite plastic, etc., which has a certain deformation capacity and can generate slight deformation during the extension or retraction of the telescopic rod 6, so as to better adapt to the contour changes of the discharge port pipe diameter of different silage filling machines 18, thereby improving the fit and sealing between the adjustment device and the equipment, and enhancing the structural stability.

[0047] The inner edge of the arc-shaped portion 7 of the second diameter adjustment device 22 is fixedly connected to the elastic connecting tube 1. Preferably, a secure assembly is achieved using methods such as bonding, hot melting, screws, or rivets to ensure that the arc-shaped portion 7 always moves synchronously with the elastic connecting tube 1 during the extension and retraction process, maintaining the overall structure's sealing and stability. Several pawls 23 are provided on the outer edge of the arc-shaped portion 7 to engage the edge of the silage bag, preventing relative slippage between the elastic connecting tube 1 and the silage bag during material filling. When the telescopic rod 6 retracts, the arc-shaped portions 7 sequentially adhere in the circumferential direction, forming a ring structure. Example 4

[0048] Based on the above embodiment 1, referring to Figure 2, the power mechanism is a manually driven structure, including a handwheel 16 located on the outside of the housing 2. The handwheel 16 is supported on the housing 2 by a wheel axle, and its wheel disk is located on the outside of the housing 2 for easy manual rotation. The wheel axle of the handwheel 16 is connected to a rotating wheel 9 located inside the housing 2 by gear meshing. By rotating the handwheel 16, the user can drive the rotating wheel 9 to rotate, thereby driving multiple telescopic rods 6 connected to the rotating wheel 9 to move synchronously along the radial direction of the housing, realizing the opening and closing adjustment of the first or second diameter adjustment device. This structure has the advantages of simple structure, intuitive operation, and no need for power supply.

[0049] When the user rotates the handwheel 16, the axle drives the gear to rotate, and through gear meshing, drives the rotating wheel 9 to rotate in the set direction. As the rotating wheel 9 rotates, the multiple arc-shaped rails 10 mounted on it simultaneously drive the embedded protruding keys 11 to move synchronously, thereby pushing the multiple telescopic rods 6 connected to the protruding keys 11 to extend or retract synchronously along the radial direction of the housing 2, completing the opening and closing adjustment of the first diameter adjustment device 21 or the second diameter adjustment device 22. Example 5

[0050] Based on the above embodiment 1, referring to Figure 3, the power mechanism is an electric drive structure, including a drive motor 12 installed inside the housing 2. A drive gear is provided on the output shaft of the drive motor 12, and the drive gear meshes with the gear part of the rotating wheel 9.

[0051] During the rotation of the rotating wheel 9, several arc-shaped rails 10 set on it simultaneously drive the convex key 11 embedded therein to move synchronously, thereby driving the telescopic rod 6 connected to the convex key 11 to extend or retract synchronously along the radial direction of the housing 2, completing the opening and closing adjustment of the first diameter adjustment device 21 or the second diameter adjustment device 22, and realizing the rapid adjustment and automatic bonding of the connection diameter between the silage filling machine and the silage bag.

[0052] To ensure the normal operation of the drive motor 12, a battery assembly should be installed inside the housing 2 to provide an independent power supply for the motor. Additionally, a controller should be provided to control the motor's start / stop, rotation direction switching, and speed adjustment, meeting the needs of different operating conditions. This electric drive structure offers advantages such as convenient operation, high adjustment efficiency, and strong adaptability, making it particularly suitable for automated operation scenarios with high requirements for adjustment response speed and accuracy.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
