Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a folding conveyor. Background Technology

[0002] Conveyors are widely used in material handling. While the domestic market offers a variety of conveyors, most employ a direct belt drive system using conveyor rollers, which has significant drawbacks. Firstly, the installation and adjustment precision of the two drive rollers is difficult to guarantee, causing the belt to easily slip to one side during operation, potentially even jamming and leading to equipment downtime. This significantly impacts work efficiency, increases maintenance costs, and raises the risk of production interruptions. Secondly, in scenarios requiring long-distance material transport, traditional conveyors are bulky and space-consuming, making them unsuitable for space-constrained applications such as vehicle-mounted conveyors, thus limiting their application scope. To adapt to diverse production needs, there is an urgent need to develop a new type of conveyor that is stable in operation and occupies less space. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a foldable conveyor, which solves the problems of large size and space occupation of existing conveyors.

A driven shaft rotates within the lower section of the conveyor, with a pair of driven sprockets at both ends. A chain with lugs is wound between the drive sprockets and the driven sprockets. Several chain connecting plates are installed between the pair of lugs. Both ends of the chain connecting plates are fixedly connected to the side lugs of the lugs on both sides of the chain connecting plates. A conveyor belt is fixedly installed on the upper wall of the chain connecting plates, and a pad is fixedly installed on the lower wall.

[0013] This utility model provides a folding conveyor, which has the following advantages:

[0014] By replacing the traditional belt drive with chain drive, the chain and sprockets mesh tightly, avoiding the problem of slippage and solving the problems of belt deviation and jamming. This greatly improves the stability and reliability of equipment operation, ensures production continuity, and reduces maintenance frequency and costs. The extension and retraction of the middle and upper sections of the conveyor can be realized by the extension and retraction of the boom extension cylinder and the forearm extension cylinder, respectively, effectively reducing the space occupied by the equipment and meeting the needs of space-constrained scenarios such as vehicle-mounted installations, thereby improving the applicability and flexibility of the equipment.

[0015] Arc tracks are installed at the lower section of the conveyor near the first bend point and at the middle section of the conveyor near the second bend point to allow the chain to move smoothly during folding and prevent the chain from jamming due to large turns during folding; the spring tension rod at the tail of the lower section of the conveyor ensures that the chain is always taut, avoids chain folding, ensures smooth chain operation during folding and unfolding, and improves the convenience and stability of equipment operation;

[0016] The hopper facilitates material entry into the conveyor, while side baffles prevent material spillage. The conveyor belt material can be rubber, PVC, or wire mesh, allowing users to choose according to the characteristics of the conveyed material. The drive unit can be a hydraulic motor or an electric motor to adapt to different power requirements. The dimensions of each section of the conveyor can also be adjusted according to the conveying distance to meet the conveying needs under different working conditions. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides a technical solution: a folding conveyor, including a conveyor body, which is composed of a lower section 1, a middle section 2, and an upper section 3. The bottom of the middle section 2 is hinged to the lower section 1 through a first bending point 4, and the top is hinged to the upper section 3 through a second bending point 5. A pair of boom extension cylinders 6 are movably installed on the outer walls of both sides of the lower section 1, and the telescopic ends of the pair of boom extension cylinders 6 are movably connected to the outer walls of both sides of the middle section 2. A pair of forearm extension cylinders 7 are movably installed on the outer walls of both sides of the middle section 2. The extension end of the arm-extension cylinder 7 is movably connected to the outer walls on both sides of the upper section 3 of the conveyor. The upper section 3 of the conveyor is equipped with a drive shaft 8, and a pair of drive sprockets are provided at both ends of the drive shaft 8. The lower section 1 of the conveyor is equipped with a driven shaft 9, and a pair of driven sprockets are provided at both ends of the driven shaft 9. A chain with lugs 10 is wound between the drive sprockets and the driven sprockets. Several chain connecting plates 11 are installed between the pair of chains with lugs 10. The two ends of the chain connecting plates 11 are fixedly connected to the side lugs of the chains with lugs 10 on both sides. A conveyor belt 12 is fixedly installed on the upper wall of the chain connecting plate 11, and a pad 13 is fixedly installed on the lower wall.

[0025] By adopting the above technical solution, during operation, the drive device 15 drives the drive shaft 8 to rotate, and the drive sprocket on the drive shaft 8 rotates accordingly. The driven sprocket and driven shaft 9 are driven to rotate through the lug chain 10. The lug chain 10 slides on the chain guide rail. The chain connecting plate 11 connects the lug chains 10 on both sides and fixes the conveyor belt 12. The pad block 13 ensures the stability of the position of the conveyor belt 12. The material enters from the receiving hopper 17 and is conveyed on the baffle conveyor belt 12. When the equipment needs to be folded, the boom extension cylinder 6 and the forearm extension cylinder 7 extend and retract, so that the middle section 2 and the upper section of the conveyor rotate and fold around the first bending point 4 and the second bending point 5 respectively, realizing the chain drive, folding function and material conveying, laying the foundation for stable and efficient material conveying.

[0026] In this embodiment, the lower section 1 of the conveyor near the first bending point 4 and the middle section 2 of the conveyor near the second bending point 5 are both provided with arc tracks 14.

[0027] By adopting the above technical solution, when the conveyor is folded or unfolded, the eared chain 10 smoothly transitions along the arc track 14 when it passes through the first bending point 4 and the second bending point 5, avoiding chain jamming due to right-angle bends, ensuring smooth folding and unfolding operations, and improving the reliability of equipment operation.

[0028] In this embodiment, the upper section 3 of the conveyor is provided with a drive device 15 connected to the drive shaft 8, and the drive device 15 is a hydraulic motor or an electric motor.

[0029] By adopting the above technical solution, the drive device 15, such as a hydraulic motor or electric motor, is started to drive the drive shaft 8 to rotate, providing power to the conveyor and driving the conveyor belt 12 to achieve material conveying. The appropriate type of drive device 15 can be selected according to actual needs and working conditions.

[0030] In this embodiment, the conveyor body is provided with a chain guide rail, and the lug chain 10 is slidably connected to the chain guide rail.

[0031] By adopting the above technical solution, the chain guide rail plays a guiding and supporting role for the lug chain 10, preventing the chain from deviating or shaking during operation, and further improving the stability and reliability of the conveyor transmission system.

[0032] In this embodiment, the lower section 1 of the conveyor is provided with a receiving hopper 17.

[0033] By adopting the above technical solution, the material enters the conveyor through the receiving hopper 17, and the receiving hopper 17 guides the material to fall smoothly onto the conveyor belt 12, thus starting the material conveying process.

[0034] In this embodiment, the conveyor body is further configured with baffles 18 on both sides.

[0035] By adopting the above technical solution, the baffle plate 18 effectively prevents material spillage, avoiding material loss and pollution of the working environment.

[0036] In this embodiment, the conveyor belt 12 is further configured to be a conveyor belt 12 with baffles.

[0037] By adopting the above technical solution, the baffle conveyor belt 12 is designed for conveying granular materials, effectively preventing material slippage, improving the stability and reliability of material conveying, and meeting the conveying needs of specific materials.

[0038] In this embodiment, the conveyor belt 12 is further configured to be made of any one of rubber, PVC, and steel wire mesh.

[0039] In this embodiment, the lower section 1 of the conveyor is provided with a spring tensioning rod for tightening the lug chain 10.

[0040] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0041] Example: During preparation, the equipment is initially in a folded state. The boom extension cylinder 6 is activated, causing its telescopic end to push the middle section 2 of the conveyor to rotate and unfold around the first bending point 4. Then, the forearm extension cylinder 7 is activated, pushing the upper section 3 of the conveyor to rotate and unfold around the second bending point 5 until the conveyor reaches the unfolded state required for operation. The drive device 15 is then activated, driving the drive shaft 8 to rotate, which in turn drives the drive sprocket, the lug chain 10, the driven sprocket, and the driven shaft 9 to rotate, causing the conveyor belt 12 to start running. The material is fed into the conveyor through the receiving hopper 17. The material moves towards the output end on the baffle conveyor belt 12 as the conveyor belt 12 rotates. During the conveying process, the baffle plates 18 on both sides prevent the material from spilling.

[0042] After the material is conveyed, turn off the drive unit 15 and stop the conveyor belt 12 from running; start the boom extension cylinder 7, so that it retracts and drives the upper section 3 of the conveyor to rotate and fold around the second bending point 5; then start the boom extension cylinder 6, so that it retracts and drives the middle section 2 of the conveyor to rotate and fold around the first bending point 4, folding the conveyor to a suitable state for storage or transfer.
