Description

Technical Field

[0001] This utility model relates to the field of conveyor technology. Background Technology

[0002] In fruit and vegetable production, large quantities of produce require efficient collection and transfer via conveyors. In large-scale fruit and vegetable production, the receiving belt conveyor used for transporting produce is typically designed as a lightweight, flexible mobile or fixed device. Its core component is a circular rubber belt or a conveyor belt made of special material, driven by a motor to rotate rollers in a circular motion. It often has a front end with a certain inclination angle or adjustable height to directly receive fruits or vegetables that have spilled after manual or mechanical harvesting. The conveyor belt runs smoothly, gently transporting the scattered fruits backward or horizontally, achieving initial buffering, collection, and diversion during the transport process, providing a continuous and orderly flow of raw materials for subsequent sorting, washing, or packing stages.

[0003] However, in existing material receiving belt conveyors, the conveyor belt surface is often kept horizontal by the conveyor rollers during operation. However, due to site limitations, the conveyor belt surface is often set at an angle, making it easy for fruits and vegetables to hit the side walls of the conveyor belt. At the same time, the belt is prone to slippage and deviation during long-term operation, resulting in damage to the fruits and vegetables. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed support device for a material receiving belt conveyor in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A fixed support device for a receiving belt conveyor includes a frame, conveyor rollers, and a conveyor belt. Auxiliary rollers are symmetrically arranged in pairs on the frame, facing the conveyor rollers towards the middle of the conveyor belt. The auxiliary rollers are inclined towards the middle of the conveyor belt. A first adjustment component is provided on the frame to adjust the inclination angle of the auxiliary rollers. A support frame is provided at the bottom of the frame, and a mounting platform is attached to the support frame. The conveyor rollers and the conveyor belt are mounted on the mounting platform. A second adjustment component is provided on the support frame to adjust the inclination angle of the mounting platform. The second adjustment component includes a spring damping rod on the support frame and a lifting support at the bottom of the spring damping rod. A lifting shaft is provided on the lifting support, with its upper end connected to the bottom end of the spring damping rod. An adjustment component is provided on the lifting support to adjust the length of the lifting shaft.

[0007] The above solution uses auxiliary rollers for correction. Symmetrically arranged inclined auxiliary rollers continuously contact the two edges of the conveyor belt, forming a guiding force towards the center. The support frame is easy to support the ground, and the spring shock absorber absorbs the running vibration. At the same time, the mounting platform is set up and the tilt angle of the mounting platform is adjusted by the lifting shaft, thereby adjusting the tilt angle of the conveyor belt. The entire adjustment device has a compact structure, avoids fruits and vegetables from hitting the side wall, and improves the system's adaptability.

[0008] Furthermore, the first adjustment component includes a long shaft disposed at the end of the auxiliary roller, the long shaft being hinged to the mounting platform, an arc-shaped groove being provided between the long shaft and the mounting platform, and a sliding rod being bolted into the arc-shaped groove, the sliding rod being fixed to the end of the long shaft.

[0009] With the above scheme, when it is necessary to adjust the curvature of the belt surface, the slide bar moves in the arc groove, driving the long shaft to rotate synchronously, thereby adjusting the rotation angle of the auxiliary roller. After the adjustment is completed, the slide bar is fixed with bolts, and the adjustment is completed synchronously.

[0010] Furthermore, an auxiliary tension spring is provided between the arc-shaped groove and the slide bar, and the auxiliary tension spring has a tendency to make the auxiliary roller stick to the conveyor belt.

[0011] Through the above scheme, the auxiliary tension spring always applies tension to the slide bar, so that the auxiliary roller is in close contact with the edge of the conveyor belt, compensating for the gap caused by belt deformation or vibration, and maintaining continuous correction force.

[0012] Furthermore, the spring damping rods are provided in several groups and distributed on the support frame according to their weight distribution.

[0013] The above solution distributes the load to avoid single-point overload and reduces the risk of deformation of the mounting platform.

[0014] Furthermore, the adjustment assembly includes a ratchet assembly located at the bottom end of the lifting support, the ratchet assembly having a drive tooth coaxially arranged, the side wall of the lifting shaft having a rack that meshes with the drive tooth, and a pad block stored on one side of the lifting shaft.

[0015] The above scheme uses a ratchet drive gear to engage a rack to control the extension and retraction of the lifting shaft. After adjustment, inserting pads for reinforcement reduces the risk of device failure.

[0016] Furthermore, the ratchet assembly is provided in two sets, symmetrically distributed on both sides of the lifting support. The two sets of ratchet assemblies are coaxially arranged and driven to rotate synchronously by the same handle.

[0017] The above solution uses a single handle to synchronously drive the ratchet groups on both sides, ensuring that the lifting shaft moves up and down synchronously and avoiding belt misalignment caused by asynchronous adjustment.

[0018] Furthermore, positioning hooks are provided on both sides of the mounting platform, and inclined anchor rods are connected to the positioning hooks.

[0019] With the above scheme, the inclined anchor rod is fixed to the ground and connected to the installation platform through the hook to form a triangular traction, which counteracts the gravity slippage component when the conveyor tilts.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. Correction is achieved by setting auxiliary rollers, namely, symmetrically set inclined auxiliary rollers continuously contact the two sides of the conveyor belt to form a guiding force towards the center. The support frame is easy to support the ground, and the vibration of operation is absorbed by the spring shock absorber. At the same time, the mounting platform is set up and the tilt angle of the mounting platform is adjusted by the lifting shaft, thereby adjusting the tilt angle of the conveyor belt. The entire adjustment device has a compact structure, avoids fruits and vegetables from hitting the side wall, and improves the adaptability of the system. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1 to 3 As shown, this embodiment provides a fixed support device for a receiving belt conveyor, including a frame 11, conveyor rollers 12, and a conveyor belt 13. Auxiliary rollers 14 are symmetrically arranged in pairs on the frame 11 on the side of the conveyor rollers 12 facing the conveyor belt 13. The auxiliary rollers 14 are inclined and positioned towards the middle of the conveyor belt 13. A first adjustment component for adjusting the inclination angle of the auxiliary rollers 14 is provided on the frame 11. A support frame 15 is provided at the bottom of the frame 11, and a mounting platform 16 is attached to the support frame 15. The conveyor rollers 12 and the conveyor belt 13 are mounted on the mounting platform 16. A second adjustment assembly is provided to adjust the tilt angle of the mounting platform 16. The second adjustment assembly includes a spring damping rod 17 mounted on the support frame 15. The top end of the spring damping rod 17 is hinged to the top of the support frame 15. The second adjustment assembly also includes a lifting support 18 located at the bottom end of the spring damping rod 17. A lifting shaft 19 is provided on the lifting support 18. The upper end of the lifting shaft 19 is connected to the bottom end of the spring damping rod 17. Several sets of spring damping rods 17 are distributed on the support frame 15 according to their weight distribution. An adjustment assembly for adjusting the length of the lifting shaft 19 is provided on the lifting support 18.

[0030] The deviation is corrected by setting auxiliary rollers 14, that is, the symmetrically set inclined auxiliary rollers 14 continuously contact the two sides of the conveyor belt 13 to form a guiding force towards the center. The support frame 15 is easy to support the ground. At the same time, the spring shock absorber 17 absorbs the running vibration, disperses the load to avoid single-point overload, and reduces the risk of deformation of the mounting platform 16. Meanwhile, the mounting platform 16 is set to be raised and lowered by the lifting shaft 19, which drives the tilt angle of the mounting platform 16 to be adjusted, thereby realizing the adjustment of the tilt angle of the conveyor belt 13. The entire adjustment device has a compact structure, avoids fruits and vegetables from hitting the side wall, and improves the system adaptability.

[0031] like Figures 1 to 3 As shown, in order to improve the stability of the device, positioning hooks 20 are provided on both sides of the mounting platform 16. An inclined anchor rod 21 is connected to the positioning hook 20. The inclined anchor rod 21 is fixed to the ground and forms a triangular traction by connecting to the mounting platform 16 through the hook, which counteracts the gravity slip component when the conveyor tilts.

[0032] like Figures 1 to 3As shown, the first adjustment assembly includes a long shaft 22 located at the end of the auxiliary roller 14. The long shaft 22 is hinged to the mounting platform 16. An arc-shaped groove 23 is provided between the long shaft 22 and the mounting platform 16. A sliding rod 24 is bolted into the arc-shaped groove 23 and fixed to the end of the long shaft 22. When it is necessary to adjust the curvature of the belt surface, the sliding rod 24 moves within the arc-shaped groove 23, causing the long shaft 22 to rotate synchronously, thereby adjusting the rotation angle of the auxiliary roller 14. After adjustment, the sliding rod 24 is fixed with bolts, completing the adjustment synchronously. An auxiliary tension spring 28 is provided between the arc-shaped groove 23 and the sliding rod 24. The auxiliary tension spring 28 tends to make the auxiliary roller 14 press against the conveyor belt 13. The auxiliary tension spring 28 always applies tension to the sliding rod 24, making the auxiliary roller 14 press against the edge of the conveyor belt 13, compensating for gaps caused by belt deformation or vibration, and maintaining continuous correction force.

[0033] like Figures 1 to 3 As shown, the adjustment assembly includes a ratchet assembly 25 located at the bottom of the lifting support 18. The ratchet assembly 25 has a coaxially mounted drive tooth 29. Racks 30, which mesh with the drive tooth 29, are distributed on the side wall of the lifting shaft 19. The drive tooth 29 is internally located and meshes with the racks 30 on the lifting shaft 19. A pad 27 is placed on one side of the lifting shaft 19. Rotating the ratchet assembly 25 synchronously drives the drive tooth 29, and the racks 30 meshing with the drive tooth 29 control the extension and retraction of the lifting shaft 19. After adjustment, the ratchet assembly 25 self-locks, and the pad 27 is inserted into the lower end of the lifting shaft 19 for reinforcement and support, reducing the risk of device failure. Two ratchet assemblies 25 are provided, symmetrically distributed on both sides of the lifting support 18. The two ratchet assemblies 25 are coaxially mounted and synchronously driven by the same handle. A single handle synchronously drives both ratchet assemblies 25, ensuring synchronous lifting and lowering of the lifting shaft 19 and preventing belt misalignment caused by asynchronous adjustment.

[0034] It should be noted that the connection relationships of components not specifically mentioned in this application are all assumed to be based on existing technology. Since they do not involve the inventive point and are commonly used in existing technology, the structural connection relationships are not described in detail.
