Description

Technical Field

[0001] This utility model belongs to the technical field of grain conveyors, specifically relating to a grain conveyor with a hidden winding device. Background Technology

[0002] Grain conveyors are mobile, steering belt conveyors primarily used for bulk grain loading operations in flat warehouses. They consist mainly of a conveying section, a steering section, and a traveling section, and are suitable for loading operations in large and medium-sized grain warehouses. During operation, grain conveyors often need to be placed outdoors, requiring long power cords for operation. After use, to store the long power cords, a winding reel is usually installed on one side of the conveyor frame. To meet winding capacity requirements, the winding reel is often designed to be quite long, protruding beyond the frame. However, this design not only occupies extra lateral space, compromising the overall aesthetics of the equipment, but also creates a rigid protrusion that can easily cause workers to trip and be injured in densely populated or busy grain warehouse environments, especially at night or in low-light conditions. Furthermore, the protruding part is susceptible to impact damage during conveyor movement, potentially causing structural damage to the winding reel. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a grain conveyor with a hidden winding device.

[0004] To solve the above-mentioned technical problems, the present invention provides a grain conveyor with a concealed winding device, comprising a grain conveyor body. A plurality of winding mechanisms for winding power cords are spaced apart along the length of the grain conveyor body on one side. Each winding mechanism includes a fixed base fixedly connected to the grain conveyor body, a plurality of positioning rings spaced apart at the top of the fixed base along the width of the grain conveyor body, and a winding rod slidably connected within the positioning rings. A locking assembly is provided at the top of the fixed base, and a plurality of locking portions cooperating with the locking assembly are spaced apart along the length of the winding rod at the bottom. The locking assembly can lock with the locking portions to restrict the sliding of the winding rod.

[0005] Furthermore, the locking assembly includes two connecting bolts spaced apart at the top of the fixed base along a length direction perpendicular to the winding rod, a sliding plate slidably sleeved outside the two connecting bolts, a plug-in block disposed on the top surface of the sliding plate, and a first telescopic spring disposed between the sliding plate and the fixed base for pushing the sliding plate to move toward the winding rod; the locking part includes a plurality of plug-in slots spaced apart at the bottom of the winding rod along the length direction of the winding rod, and the plug-in block can be inserted into any of the plug-in slots.

[0006] Furthermore, the cross-section of the plug block is an isosceles triangle, and the plug groove is a "V" shaped groove that matches the shape of the plug block.

[0007] Furthermore, one end of the winding rod is threadedly connected to a limiting plate, which is located below the grain conveyor body, and the other end of the winding rod is provided with a wire-blocking disc, which is located on the outside of the grain conveyor body.

[0008] Furthermore, each of the positioning rings is symmetrically distributed with limiting grooves, and the two sides of the winding rod are provided with limiting parts that are adapted to the limiting grooves.

[0009] Furthermore, the fixing base is U-shaped and includes a top plate and a first side plate and a second side plate located at both ends of the top plate. The first side plate is provided with threaded holes that penetrate both inside and outside, and fixing bolts for fixing the fixing base are threaded into the threaded holes.

[0010] Furthermore, the line guide plate is provided with a clearance hole, the clearance hole is positioned corresponding to the fixing bolt, and the diameter of the clearance hole is larger than the diameter of the fixing bolt.

[0011] Furthermore, a pressing plate is provided at one end of the fixing bolt near the second side plate. The fixing bolt engages with the threaded hole to drive the pressing plate to move toward the second side plate. The second side plate and the pressing plate respectively form a clamp from both sides of the grain conveyor body to fix the fixing seat on the grain conveyor body.

[0012] Furthermore, a second telescopic spring is sleeved on the outside of the fixing bolt, and the two ends of the second telescopic spring abut against the first side plate and the extrusion plate, respectively.

[0013] Furthermore, anti-slip pads are provided on the opposite sides of the second side plate and the extrusion plate.

[0014] This utility model discloses a grain conveyor with a concealed winding device. The winding rod can be slidably stored on the side of the grain conveyor's main support frame. When not in use, it does not protrude from the outside of the support frame, completely eliminating the risk of tripping and injury caused by the rigid protrusion of the traditional winding reel, significantly improving safety, especially at night or in low-light conditions. Furthermore, the sliding connection between the positioning ring and the winding rod allows for flexible adjustment of the winding rod's extension length according to the power cord length, meeting different winding capacity requirements without the need for a fixed long winding reel, resulting in a more flexible design. The locking assembly can fix the winding rod in any position, locking it during use to prevent slippage and unlocking it for easy sliding back to its original position when storing, ensuring convenient, stable, and reliable operation. The limiting groove of the positioning ring cooperates with the limiting part of the winding rod, guiding the winding rod to slide smoothly and preventing free rotation. The fixing base is fixed to the support frame by fixing bolts, a compression plate, and a second telescopic spring, ensuring a secure installation and providing a certain degree of cushioning performance to adapt to the vibration environment during equipment operation.

Detailed Implementation

[0021] The following detailed implementation methods further illustrate the following:

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5This utility model discloses a grain conveyor with a concealed winding device, comprising a grain conveyor body 1. A plurality of winding mechanisms 2 for winding power cords are spaced apart along the length of the grain conveyor body 1 on one side. Each winding mechanism 2 includes a fixed base 21 fixedly connected to the grain conveyor body 1, a plurality of positioning rings 22 spaced apart at the top of the fixed base 21 along the width of the grain conveyor body 1, and a winding rod 23 slidably connected within the positioning rings 22. A locking assembly 3 is provided at the top of the fixed base 21, and a plurality of locking parts 4, cooperating with the locking assembly 3, are spaced apart along the length of the winding rod 23 at the bottom. The locking assembly 3 can lock with the locking parts 4 to restrict the sliding of the winding rod 23. The winding rod 23 can be slidably stored in the side of the grain conveyor body 1, and does not need to protrude from the outside of the grain conveyor body 1 when not in use, eliminating the risk of tripping or injury caused by the rigid protrusion of the traditional winding reel. Furthermore, the slidable connection between the positioning ring 22 and the winding rod 23 allows for flexible adjustment of the extension length of the winding rod 23 according to the power cord length, resulting in a more flexible design. The locking assembly can fix the winding rod 23 in any position, locking it during use to prevent slippage, and unlocking it for easy sliding reset when storing, making operation convenient, stable, and reliable.

[0023] In this embodiment, there are two take-up mechanisms 2, which are spaced apart along the length of the conveyor body 1 on one side of the conveyor body 1. To facilitate the installation and disassembly of the entire take-up mechanism 2, in this embodiment, the fixing base 21 is U-shaped. The fixing base 21 includes a top plate 211 and a first side plate 212 and a second side plate 213 located at both ends of the top plate 211. The first side plate 212 has a through-hole 2121, and a fixing bolt 5 for fixing the fixing base 21 is threaded into the through-hole 2121. The U-shaped fixing base 21's opening design can accommodate conveyor supports with different cross-sectional shapes (such as rectangular tubes and round tube supports). By tightening the fixing bolts 5, the support can be clamped without customized processing, significantly improving the equipment's versatility. Furthermore, the threaded connection facilitates disassembly and maintenance, adapting to equipment repair or replacement needs. Furthermore, the spacing between the two winding mechanisms 2 can be adjusted according to the length of the power cord. If the power cord is long, the spacing between the two winding mechanisms 2 can be increased to increase the length of the power cord that can be stored, which can prevent the power cord from becoming loose due to insufficient storage capacity.

[0024] To improve the fixing effect of the fixing seat 21, a pressing plate 6 is provided at the end of the fixing bolt 5 near the second side plate 213. The fixing bolt 5 is threadedly engaged with the threaded hole 2121, driving the pressing plate 6 to move towards the second side plate 213. The second side plate 213 and the pressing plate 6 respectively form a clamp from both sides of the grain conveyor body 1 to fix the fixing seat 21 to the grain conveyor body 1. Since the clamping force is concentrated when fixing the fixing seat 21 with a single bolt, it is easy to cause local loosening of the connection. The pressing plate 6 increases the contact area with the conveyor support, converting the axial tension of the fixing bolt 5 into a uniform lateral clamping force, thereby improving the structural strength of the connection. To address the problem of relative sliding caused by the smooth contact surface of the metal fixing seat 21 and the conveyor support and insufficient friction, it is necessary to increase the friction between the pressing plate 6 and the second side plate 213 and the conveyor body 1 support. In this embodiment, anti-slip pads 8 are provided on the opposite sides of the second side plate 213 and the pressing plate 6. Specifically, the anti-slip pad 8 can be made of a high-friction coefficient material such as rubber, so that the fixed seat 21 is not prone to sliding or displacement even when the equipment is frequently vibrating or tilting. Meanwhile, a second telescopic spring 7 is sleeved on the outside of the fixing bolt 5, with its two ends abutting against the first side plate 212 and the extrusion plate 6, respectively. The second telescopic spring 7 buffers the vibration energy of the conveyor body 1 during operation, reduces rigid collisions between the fixed seat 21 and the support, and extends the service life of the connecting components. The elastic deformation of the second telescopic spring 7 automatically compensates for connection gaps caused by vibration or temperature changes, continuously maintaining the clamping force between the extrusion plate 6 and the support, ensuring the long-term stable installation of the take-up mechanism 2.

[0025] After the winding mechanism 2 is fixedly installed, when the power cord needs to be stored, the operator pulls the winding rod 23 so that it protrudes from the side of the conveyor body 1. If the power cord is long, the operator can pull out the winding rods 23 of both winding mechanisms 2 and wind the power cord between the two winding rods 23. If the power cord is short, only one winding rod 23 needs to be pulled out. To prevent the winding rod 23 from disengaging from the positioning ring 22 when the winding rod 23 is pulled, a limiting plate 231 is threaded to one end of the winding rod 23. The limiting plate 231 is located below the grain conveyor body 1, and a wire-blocking disc 232 is provided at the other end of the winding rod 23. The wire-blocking disc 232 is located on the outside of the grain conveyor body 1. By setting the limiting plate 231 and the wire-blocking disc 232, the wire can be prevented from slipping off the positioning ring 22 when the winding rod 23 is slidable. Simultaneously, the wire-blocking disc 232 prevents the power cable from slipping off the end of the winding rod 23, ensuring the power cable is tightly wound around the winding rod 23. In this embodiment, the wire-blocking disc 232 is fixed to one end of the winding rod 23 by welding, and the limiting plate 231 is fixed to one end of the winding rod 23 by a threaded connection. This design also facilitates the installation and removal of the winding rod 23 and the positioning ring 22.

[0026] Once the winding rod 23 protrudes from the side of the conveyor body 1, the operator can then retract the power cord onto the outside of the winding rod 23. To prevent the winding rod 23 from rotating within the positioning ring 22 during retraction, causing the power cord to loosen, symmetrically distributed limiting grooves 221 are provided on each positioning ring 22. Simultaneously, limiting portions 233, adapted to the limiting grooves 221, are provided on both sides of the winding rod 23. The tight fit between the limiting portions 233 and the limiting grooves 221 restricts the rotational freedom of the winding rod 23 around its own axis. When the operator pulls or pushes the winding rod 23 to perform winding or unwinding operations, the limiting portions 233 can only slide along the direction of the limiting grooves 221, ensuring that the winding rod 23 can only move linearly along the width direction of the grain conveyor body 1. This avoids problems such as spiral winding and knotting of the power cord caused by the rotation of the winding rod 23, allowing the power cord to be wound evenly along the axial direction of the winding rod 23, ensuring the neatness and orderliness of the power cord storage, and improving storage quality and efficiency. To prevent the winding rod 23 from sliding freely during storage, in this embodiment, the locking assembly 3 includes two connecting bolts 31 spaced apart at the top of the fixing base 21 along the length direction perpendicular to the winding rod 23, a sliding plate 32 slidably sleeved outside the two connecting bolts 31, an insertion block 33 disposed on the top surface of the sliding plate 32, and a first telescopic spring 34 disposed between the sliding plate 32 and the fixing base 21 for pushing the sliding plate 32 toward the winding rod 23. The locking part 4 includes a plurality of insertion slots 41 spaced apart at the bottom of the winding rod 23 along the length direction of the winding rod, and the insertion block 33 can be inserted into any of the insertion slots 41. When the winding rod 23 is pulled, the operator can press the sliding plate 32 to cause the plug block 34 to exit from the plug slot 41. When the winding rod 23 is adjusted to a suitable position, the first telescopic spring 34 will push the sliding plate 32 under elastic force, thereby inserting the plug block 33 into the plug slot 41 and fixing the winding rod 23. At this time, the power cord can be stored. Through the cooperation of the locking component 3 and the locking part 4, the winding rod 23 can be prevented from sliding freely when storing the power cord. At the same time, after the winding rod 23 is retracted after storage, the cooperation of the locking component 3 and the locking part 4 can also limit the accidental sliding of the winding rod 23.

[0027] For easier operation, in this embodiment, the cross-section of the plug-in block 33 is designed as an isosceles triangle, and the plug-in groove 41 is designed as a "V"-shaped groove that matches the shape of the plug-in block 33. When the winding rod 23 slides to the target position, the plug-in block 33 aligns with the new plug-in groove 41. At this time, the elastic restoring force of the first telescopic spring 34 pushes the sliding plate 32 to move towards the winding rod 23, and the plug-in block 33 automatically slides into the groove along the inclined surface of the plug-in groove 41. As the plug-in block 33 goes deeper, it fits tightly against the "V"-shaped surface of the plug-in groove 41, forming a stable mechanical lock, fixing the winding rod 23 in the current position. When it is necessary to slide the winding rod 23 to adjust its position, the operator directly applies a pulling or pushing force along the width direction of the grain conveyor body 1. At this time, the inner wall of the "V"-shaped insertion groove 41 at the bottom of the winding rod 23 contacts the inclined surface of the isosceles triangular insertion block 33. Due to the characteristics of the inclined surface structure, the insertion groove 41 applies a lateral component force to the insertion block 33. This component force pushes the sliding plate 32 to overcome the elastic force of the first telescopic spring 34 and slide along the connecting bolt 31 away from the winding rod 23 until the insertion block 33 is completely disengaged from the current insertion groove 41, thereby unlocking the winding rod 23 and allowing it to slide freely. By using the isosceles triangular cross section of the insertion block 33 in conjunction with the inclined surface of the "V"-shaped insertion groove 41, the problem of inconvenient operation of the locking assembly is solved, allowing the operator to achieve sliding unlocking of the winding rod 23 by applying only a linear pulling or pushing force, without the need to press the sliding plate 32 additionally. Utilizing the inclined plane guiding principle, when the winding rod 23 is slid, the plug block 33 can automatically slide out or slide in along the inclined plane of the plug slot 41. The unlocking process does not require additional manual action from staff, making it more convenient.

[0028] Based on the above embodiments, the working principle of the grain conveyor with a concealed winding device of this utility model is as follows: First, the grain conveyor body 1 is clamped by the first side plate 212 and the second side plate 213 of the "U"-shaped fixed seat 21. Tightening the fixing bolt 5 drives the extrusion plate 6 to move towards the second side plate 213, so that the two are clamped and fixed from both sides. The anti-slip pad 8 increases the friction to prevent slippage, and the second telescopic spring 7 buffers vibration and compensates for the connection gap, ensuring that the fixed seat 21 is stably installed. The winding rod 23 cooperates with the limiting groove 221 of the positioning ring 22 through the limiting part 233, restricting its rotation around its own axis, and can only slide linearly along the width direction of the grain conveyor body 1. The limiting plate 231 and the wire-blocking disc 232 prevent the winding rod 23 from coming off from both ends. The clearance hole 2321 of the wire-blocking disc 232 avoids the fixing bolt 5 and does not affect its sliding towards the grain conveyor body 1. When the power cord needs to be stored, the winding rod 23 is pulled out directly. The inclined surface of the "V"-shaped insertion slot 41 at its bottom contacts the insertion block 33, which has an isosceles triangular cross-section. This generates a lateral force that pushes the sliding plate 32 to compress the first telescopic spring 34, causing the insertion block 33 to disengage from the current insertion slot 41, thus unlocking the cord. After the winding rod 23 is pulled out to the appropriate position, the insertion block 33 automatically slides into the corresponding insertion slot 41 under the elastic force of the first telescopic spring 34. The "V"-shaped surfaces fit tightly together to form a mechanical lock, fixing the position of the winding rod 23. At this time, depending on the length of the power cord, the operator can pull out multiple winding rods 23 of the winding mechanism 2 individually or simultaneously to wind the power cord onto one of the winding rods 23 or between multiple winding rods 23. The cord retainer 232 prevents the end of the power cord from slipping off. When no power cord is needed, push the winding rod 23 to slide towards the grain conveyor body 1 until the winding rod 23 slides into the grain conveyor body 1.

[0029] This utility model discloses a grain conveyor with a concealed winding device, which has the following advantages: The "U"-shaped fixed seat, combined with threaded connection, extrusion plate, anti-slip pad, and telescopic spring, not only facilitates installation and disassembly and is compatible with various brackets, but also evenly distributes clamping force, buffers vibration, and prevents displacement, thus enhancing connection stability and component lifespan. The concealed winding mechanism design allows the winding rod to be slidably stored on the side of the conveyor body, eliminating the collision risk caused by rigid protrusions and improving operational safety. The adjustable winding rod and multiple winding mechanism layout can flexibly adapt to power cords of different lengths, avoiding loosening problems caused by insufficient storage capacity. The locking component, in conjunction with the specially structured plug-in block and plug-in slot, achieves automatic and convenient locking and unlocking, making operation labor-saving and stable and reliable. The setting of the limit plate, the line-blocking disc, and the limit slot prevents the winding rod from slipping and rotating, ensuring that the power cord is neatly wound, improving storage quality and efficiency.

[0030] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
