Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a conveying device. Background Technology

[0002] Currently, when moving various bagged materials from low to high or from high to low, there are often no suitable tools available, requiring manual handling; this is time-consuming, labor-intensive, and physically demanding.

[0003] For example, relying on manual handling when moving fish feed from the storage area to transport trucks has significant limitations: Firstly, a single bag of fish feed typically weighs 20-50 kg, which is quite heavy; moreover, the large volume of handling requires workers to continuously bend over, carry heavy loads, and walk, resulting in extremely high labor intensity and a high risk of occupational injuries to the waist, shoulders, and other parts of the body; secondly, the efficiency of manual handling is significantly affected by factors such as physical strength, skill level, and fatigue, and the amount that a single person can handle is extremely limited; in addition, loading and unloading not only requires the cooperation of multiple people but also poses certain safety risks; especially in large-scale aquaculture scenarios, it is difficult to meet the demand for loading large amounts of feed in a short period of time, which seriously restricts the efficiency of the transportation process.

[0004] This problem is also widespread in other material handling industries, such as agriculture and construction, and in various other transport environments.

[0005] As industries become more scaled and integrated, the demand for efficient and low-labor-intensity material handling is becoming increasingly urgent. Existing manual handling methods are no longer adequate to meet the needs of industrial development, and there is an urgent need for a technological solution that can replace manual labor, reduce labor intensity, and improve handling efficiency.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0049] Please refer to Figures 1-10 A conveying device, comprising:

[0050] The frame 1 has a movable frame 2 that slides on it, and a carrying plate 3 is installed on the movable frame 2.

[0051] A drive device is mounted on the frame 1 to drive the movable frame 2 to move along the length of the frame 1.

[0052] Block 4, one block 4 is provided at the upper and lower ends on the same side of the frame 1;

[0053] A lever 5 is mounted on a movable frame 2. When the movable frame 2 reaches the top or bottom, the lever 5 contacts a stop block 4 and is actuated, thereby adjusting the lever 5 to a stop state.

[0054] Understandably, the height of both stops 4 is higher than the height of the lever 5.

[0055] like Figure 6 As shown; at this time, when the lever 5 swings upward, the drive device moves the moving frame 2 upward; correspondingly, when the lever 5 swings downward, the drive device moves the moving frame 2 downward; as Figure 7 , 8 As shown, during the upward movement of the movable frame 2, when it is about to reach the top, the lever 5 approaches the stop block 4 and is gradually blocked by the stop block 4, thus stopping the movable frame 2.

[0056] After unloading, the moving frame 2 needs to be moved down. At this time, the operator swings the lever 5 downward, and the drive device moves the moving frame 2 down. When it is about to reach the lower end, the lever 5 approaches the stop block 4 and is gradually blocked by the stop block 4, which moves it to the stop state, and the moving frame 2 stops moving.

[0057] Preferably, the positioning of the lever 5 and the stop block 4 is designed so that after the lever 5 contacts the stop block 4, the lever 5 is moved to a parallel state.

[0058] It should be noted that the frame 1, as the basic support component of the entire device, is made of steel (square steel, angle steel, etc.) and provides an installation and support platform for components such as the mobile frame 2 and the drive device. Its length can be set according to the actual handling distance, generally between 3 and 7 meters. The mobile frame 2 is slidably mounted on the frame 1 and moves along the length of the frame 1. The load plate 3 above the mobile frame 2 is used to carry materials. The load plate 3 is made of wear-resistant alloy material and can withstand the weight of heavy materials (such as tens of kilograms of fish feed) and maintain good condition during use (preferably, a metal frame made of square steel, angle steel, etc. is also set below the load plate 3). The drive device is located on the frame 1 and can drive the mobile frame 2 to move smoothly along the length of the frame 1 to realize the conveying of materials. Two stops 4 are respectively located near both ends of the frame 1 and are made of steel plate, which serve as limiters to control the movement range of the mobile frame 2. The actuating rod 5 is located on the mobile frame 2, between the two stops 4, and its height is lower than the two stops 4, cooperating with the stops 4.

[0059] It is understood that the frame 1 includes longitudinal bars along its length and several transverse bars arranged between two longitudinal bars to form a high-strength support system; preferably, end bars are provided at both ends of the frame 1 to form a closed end; furthermore, a hanging plate 13 is provided at the front end of the frame 1; it can be easily erected on the side panel of a vehicle, etc., to avoid slippage during use and improve stability and safety.

[0060] like Figure 2 As shown, the stop block 4 can be configured as a flat plate and directly fixed to the side of the frame 1; or, as shown... Figure 8 As shown, the stop block 4 is set in the form of a folded plate and is fixed to the lower side of the frame 1 (it can also be fixedly assembled on the side).

[0061] The working principle of this device is as follows: one end of the frame 1 is placed on the ground, and the other end is attached to the transport vehicle; the loading plate 3 is located near the end, and the material to be transported is placed on the loading plate 3. The drive device is started, and the drive device drives the moving frame 2 to move upward or downward along the length of the frame 1; during the movement of the moving frame 2, the actuating rod 5 moves between two stops 4. When the moving frame 2 approaches the end of the frame 1, the actuating rod 5 will contact the corresponding stop 4 and trigger a stop; thus, the material on the loading plate 3 is transported from the ground to the vehicle or from the vehicle to the ground by the movement of the moving frame 2.

[0062] In this invention, the frame 1 provides stable support for each component, ensuring the overall structural stability of the device. The moving frame 2 is driven by a drive device to achieve mechanized material transport, replacing manual handling and reducing labor intensity. Two stops 4 and a lever 5 are provided, with the stops 4 being higher than the lever 5. The movement range of the moving frame 2 is effectively limited (automatically stopped) by the cooperation of the stops 4 and the lever 5, ensuring safe operation of the device. The material is supported by the loading plate 3 on the moving frame 2, ensuring stable placement of the material during transport. Through the cooperation of these structures, the overall transport efficiency is improved, and the stability and safety of the transport process are guaranteed.

[0063] Understandably, in order to reduce wear and tear during use, rubber, wear-resistant plates, or other structures can be installed at both ends of the frame 1 to reduce contact and damage between the metal structure and the vehicle or the ground.

[0064] In some embodiments, the driving device includes: a drive motor 6, two first sprockets 61 and a chain 62; the two first sprockets 61 are respectively rotatably mounted at both ends of the frame 1 in the length direction, the chain 62 is fitted with the first sprockets 61, and the output end of the drive motor 6 is provided with a second sprocket 63 which is connected to the chain 62 for transmission; the movable frame 2 is fixed on the chain 62.

[0065] In this drive device structure, two first sprockets 61 are rotatably connected to both ends of the frame 1 and can rotate around their own axes. They are preferably made of high-strength alloy steel and can withstand the impact force and load when the chain 62 is driven. The chain 62 is made of wear-resistant steel and meshes with the two first sprockets 61 to form a closed transmission circuit. Power is transmitted through meshing with the teeth of the sprockets. The movable frame 2 is fixed on the chain 62 and forms a synchronous whole with the chain 62.

[0066] Its structural principle is as follows: when the first sprocket 61 rotates under the drive of external force, the chain 62 is driven to circulate along the length of the frame 1 through the meshing action of the sprocket teeth and the chain links; while the movable frame 2 fixed on the chain 62 moves synchronously along the frame 1 with the movement of the chain 62 under the traction of the chain 62, thereby realizing the driving function of the movable frame 2.

[0067] The advantages of this structure are: the meshing transmission between the sprocket and the chain has the characteristic of stable power transmission, which can ensure that the moving frame 2 maintains a uniform speed when carrying materials; the use of two sprockets in conjunction with the chain 62 to form a closed-loop transmission can realize the reciprocating motion of the moving frame 2, meeting the needs of bidirectional conveying; and the material selection of the chain 62 and the sprocket gives it strong wear resistance and load-bearing capacity, which can adapt to the heavy load scenarios when conveying large loads, ensuring and extending the service life of the device.

[0068] It is understandable that, such as Figure 1 As shown; ear plates, bearing seats and other structures are respectively set at both ends of the frame 1 for assembling two first sprockets 61.

[0069] Preferably, the drive motor 6 is installed below the frame 1 near the middle.

[0070] Furthermore, the drive unit also includes an adjustment mechanism.

[0071] The adjustment mechanism includes: a support frame 7 fixed to the lower side of the frame 1, and a third sprocket 71 installed on one side of the support frame 7 and whose position is adjusted by an adjusting member.

[0072] The adjusting components include: two long screws 72 arranged in a U-shape and fixedly connected as one piece, and a fixing rod 73; a third sprocket 71 is mounted on the fixing rod 73 and rotates; correspondingly, the two long screws 72 pass through the support frame 7 respectively, and adjusting nuts 74 are mounted on both sides of the support frame 7.

[0073] Preferably, a mounting bracket is also provided below the frame 1 for mounting the drive motor 6; and the mounting bracket and the support frame 7 are positioned close to each other and the length of the downward extension is controlled to avoid interference.

[0074] Understandably, the power is output from the drive motor 6 and transmitted to the chain 62 through the second sprocket 63; thereby driving each sprocket to rotate and cooperate to achieve power output.

[0075] like Figure 3 , 4 As shown in Figures 5 and 7; mounting brackets and support brackets 7 are provided at intervals along the length of the frame 1 below it; the drive motor 6 is mounted on the mounting bracket, the second sprocket 63 is fixedly mounted on the output shaft of the drive motor 6, the third sprocket 71 is rotatably connected to the support bracket 7, and the height of the third sprocket 71 is lower than the height of the second sprocket 63, and each sprocket is engaged with the chain 62.

[0076] It should be noted that both the mounting frame and the support frame 7 are made of steel. The mounting frame is used to fix and support the drive motor 6, providing a stable mounting base for the drive motor 6. The support frame 7 is used to assemble the third sprocket 71, ensuring that the third sprocket 71 is stable in position during operation. The chain 62 meshes with the two first sprockets 61, the second sprocket 63, and the third sprocket 71 to form a closed transmission circuit, transmitting power through meshing with the sprocket teeth. The drive motor 6, as the power source, is fixed on the mounting frame, and the second sprocket 63, which is fixedly mounted on its output shaft, rotates synchronously with the output shaft. The height of the third sprocket 71 is lower than that of the second sprocket 63, and it works with the second sprocket 63 to tension the chain 62. The movable frame 2 is fixed on the chain 62, forming a synchronously moving whole with the chain 62.

[0077] The advantages of this structure are: the height difference between the second sprocket 63 and the third sprocket 71 can effectively tension the chain 62, ensuring that the chain 62 and each sprocket are always tightly engaged, improving the stability and reliability of the transmission, and avoiding transmission failure caused by the loosening of the chain 62; the drive motor 6, as a power source, provides continuous and stable driving force, which, together with the transmission of the sprockets and the chain 62, can ensure that the moving frame 2 maintains a uniform speed when carrying materials.

[0078] Preferably, two long screws 72 and a fixing rod 73 are welded and fixed together; the long screws 72 pass through the support frame 7, and the third sprocket 71 is rotatably mounted on the fixing rod 73; the position of the third sprocket 71 can be changed by adjusting the adjusting nut 74; in this configuration, the structure is simple, reliable and easy to maintain.

[0079] Understandably, the two long screws 72 are made of high-strength alloy steel to ensure load-bearing capacity. Their design, with one end passing through the support frame 7, allows them to move freely along the thickness of the support frame 7, providing a direct transmission medium for adjusting the position of the third sprocket 71. Through their own displacement, they drive the fixed rod 73 and the third sprocket 71 to move synchronously, thus achieving precise adjustment of the third sprocket 71's position. The fixed rod 73 is a metal rod-shaped structure, fixedly connected to the long screws 72 at both ends, and rotatably connected to the third sprocket 71 in the middle via bearings, sleeves, and other structures. It transmits the displacement of the long screws 72 to the third sprocket 71, while providing a stable rotational support point for the third sprocket 71, ensuring that the third sprocket 71 can still rotate flexibly after position adjustment.

[0080] Understandably, the two adjusting nuts 74 are nuts that match the long screw 72; they are mounted on the long screw 72 and located on both sides of the support frame 7. After the third sprocket 71 is adjusted to the appropriate position, the two adjusting nuts 74 are tightened so that the nuts are tightly pressed against the two sides of the support frame 7. The limiting action between the nuts and the support frame 7 securely fixes the long screw 72, preventing it from shifting during device operation, thereby locking the adjustment position of the third sprocket 71.

[0081] The working principle of the three is as follows: When the position of the third sprocket 71 needs to be adjusted, first loosen the adjusting nut 74, push the long screw 72 to slide along the support frame 7, and drive the third sprocket 71 to move to the target position. Then tighten the adjusting nuts 74 on both sides to fix the long screw 72 relative to the support frame 7, complete the adjustment and locking of the position of the third sprocket 71, and ensure that it can stably play the role of tensioning the chain 62.

[0082] In some embodiments, a controller 8 is provided on the movable frame 2, and the controller 8 is electrically connected to the drive motor 6 via a wire; correspondingly, when the toggle lever 5 contacts the stop block 4 and is toggleed, the controller 8 stops the drive device.

[0083] It is understandable that the lever 5 has at least three states: an upward control for moving upward, a downward control for moving downward, and a stop control for the middle position; when the lever 5 is moved by contacting the stop block 4, the lever 5 reaches the middle position.

[0084] Preferably, the wire is wrapped with a protective sleeve.

[0085] The controller 8 uses a waterproof and dustproof shell and integrates control circuitry inside. In addition to being operated by the lever 5, it can also be controlled by buttons, remote control, etc., to adjust the start / stop and speed of the drive motor 6, thereby regulating the operating status of the moving frame 2. It is understood that the controller 8 also has a maximum travel limit, so even if the lever 5 fails, it can stop after reaching the end. This is a technology that can be implemented in the industry and will not be elaborated here.

[0086] The wire is a copper core cable, with one end connected to the controller 8 and the other end connected to the drive motor 6. It is responsible for transmitting electrical signals and power supply between the controller 8 and the drive motor 6, ensuring the electrical connection between the two. Preferably, the protective sleeve wrapped around the wire is made of wear-resistant and aging-resistant rubber material, which tightly wraps the outside of the wire to isolate external dust, moisture, oil, etc., and reduce the damage to the wire caused by friction and collision during the operation of the device.

[0087] In some embodiments, a guide groove 11 is provided on the inner side of the frame 1 in the width direction, and guide wheels 12 are respectively mounted on both ends of the movable frame 2, and the guide wheels 12 are slidably placed into the guide groove 11.

[0088] To further enhance stability, at least two guide wheels 12 are provided on each side of the movable frame 2; for example... Figure 9 As shown, a guide wheel 12 is provided on each side near the front and rear ends.

[0089] It should be noted that the guide groove 11 is a long strip-shaped groove along the length of the frame 1; when the frame 1 is made of square steel, a groove can be cut in the side wall of the square steel to connect to the interior; in other structures, the guide groove 11 structure can be set separately, and those skilled in the art can set the specific shape in a conventional way without making any restrictions.

[0090] The guide wheel 12 is made of wear-resistant rubber or steel and can roll within the guide groove 11. The function of the guide groove 11 is to provide a track for the guide wheel 12, limit the direction of movement of the guide wheel 12, and ensure that it slides smoothly along the length of the frame 1. The guide wheel 12 can rotate flexibly around its own axis, and converts the sliding friction between the moving frame 2 and the frame 1 into rolling friction within the guide groove 11, thereby reducing the resistance when the moving frame 2 moves.

[0091] The working principle of the two is as follows: when the drive device drives the mobile frame 2 to move along the length of the frame 1, the guide wheels 12 on both sides of the mobile frame 2 roll in the guide groove 11. The guide groove 11 constrains the guide wheels 12 to prevent them from deviating from the track, so that the mobile frame 2 always moves along the set path of the frame 1, and avoids the mobile frame 2 from lateral deviation or shaking during the movement.

[0092] Furthermore, the lower end of the frame 1 is equipped with casters, which facilitates the movement of the entire device.

[0093] Preferably, the moving wheels and the drive motor 6 are mounted on a single mounting bracket; for example... Figure 1 , 7 As shown, the drive motor 6 is mounted on the side of the mounting bracket, and the casters are mounted at the lower end of the mounting bracket.

[0094] As mentioned earlier, the mounting frame is positioned near the center; it employs a steel frame structure and is fixedly connected to the bottom of frame 1, providing stable bottom support for frame 1 and enhancing the overall structural strength of frame 1; the casters can rotate flexibly around their own axes. During movement, the weight of frame 1 is transferred to the casters, enabling frame 1 to be easily moved between different work locations, meeting the transportation needs of different positions.

[0095] In some embodiments, the front end of the loading plate 3 is hinged to the movable frame 2; thus, the angle of the loading plate 3 can be adjusted according to the placement angle of the frame 1 to keep it as horizontal as possible, making the load-bearing process more stable.

[0096] Correspondingly, the rear end of the mobile frame 2 is equipped with a height adjustment component 9 that supports the load plate 3, so as to adjust and lock the shape of the load plate 3.

[0097] Furthermore, bubble levels 10 are provided on both sides and the rear end of the loading plate 3 to assist in the adjustment process; such as Figure 9 , 10 As shown, there are at least three horizontal bubbles 10.

[0098] It is understandable that the height adjustment component 9 is a telescopic rod, which controls and adjusts the load plate 3 through different strokes.

[0099] Correspondingly, the bottom end of the telescopic rod is rotatably assembled with the moving frame 2, and the top end is rotatably assembled with the lower end of the carrying plate 3; or, the bottom end of the telescopic rod is fixedly assembled with the moving frame 2, and the top end abuts against the lower end of the carrying plate 3.

[0100] That is to say, the top of the height adjustment component 9 can be connected to or in contact with the carrier plate 3 to provide support; when set to the contact position, the carrier plate 3 can also be flipped over during unloading (preferably, a handle can be provided at the upper rear end of the carrier plate 3 to facilitate flipping and unloading).

[0101] The telescopic rod can be hydraulic, electric, or a combination of screw and cylinder.

[0102] Preferably, the carrier plate 3 has a cutout of the company logo.

[0103] When using this utility model, the entire unit is moved to one side of the vehicle; then, one end of the frame 1 is placed on the ground and the other end is placed on the vehicle; the state of the loading plate 3 is adjusted according to the placement shape to form a reliable carrying platform; by using the lever 5 or remote control in conjunction with the controller 8, the drive motor 6 is adjusted to drive the mobile frame 2 to move along the length of the frame 1, so as to load and unload materials.

[0104] In this invention, a frame provides stable support for each component, ensuring the overall structural stability of the device. A drive unit moves the mobile frame, enabling mechanized material transport (such as feed), replacing manual handling and reducing labor intensity. Baffles and a lever are used, with the baffles higher than the levers, effectively limiting the movement range of the mobile frame and ensuring safe operation. A loading plate on the mobile frame carries the material, ensuring its stable placement during transport. These structural elements work together to improve transport efficiency and ensure stability and safety. The meshing transmission of the sprocket and chain provides stable power transmission. Features include ensuring the mobile frame maintains a constant speed while carrying materials; employing a sprocket and chain to form a closed-loop transmission, enabling reciprocating motion of the mobile frame and meeting the needs of bidirectional material conveying; the selection of chain and sprocket materials provides strong wear resistance and load-bearing capacity, adapting to heavy-load conveying scenarios and extending the service life of the device; the height difference design between the second and third sprockets effectively tensions the chain, ensuring that the chain and each sprocket are always tightly engaged, improving the stability and reliability of the transmission, and avoiding transmission failure due to chain loosening; the motor, as the power source, provides continuous and stable driving force, which, together with the sprocket and chain transmission, ensures the mobile frame maintains a constant speed while carrying materials.
