Description
Technical Field
[0001] This utility model belongs to the field of bar production technology, and in particular relates to a buffer collection trough. Background Technology
[0002] Collection equipment is essential in bar production lines and is widely used for collecting bars. The diameter of the bars is generally [missing information]. Collect the bars into the collection trough for easy packaging. See Figure 1 The collection trough collects the bar stock into a basket for easy packaging. The bar stock is transported to the collection trough, where a lifting chain is installed. A transmission mechanism raises the lifting chain to a horizontal position, and then a feeding arm feeds the bar stock into the chain. While the lifting chain provides some cushioning, the instantaneous impact when the bar stock contacts the chain is extremely high. Furthermore, the feeding process involves feeding multiple bar stock at a time, only lowering the chain after a certain number are reached before packaging. This repeated impact can cause the lifting chain to break, or damage to components in the transmission mechanism such as the reducer and bearing housing. Additionally, when the lifting chain is raised to a high position (horizontal), the bar stock, guided by the chain, subjects the basket to a longitudinal force, causing displacement. Over time, this can lead to anchor bolt breakage or secondary grout layer damage.
[0003] A factory produces The bar stock, after being packaged, weighs at least 3.5 tons, or even 12 tons per bundle. The weight of these bars and the impact force generated when they fall are even greater, causing damage to the components and foundation of the collection trough, and shortening the service life of the collection trough. Summary of the Invention
[0004] The purpose of this invention is to provide a buffered material collection trough to solve the problem that the traditional rod collection process is prone to damage to the basic structure. By setting a buffer structure on the material collection trough, the impact force of the rods on the material basket body and the basic structure during material feeding is reduced, thereby extending the service life of the material collection trough.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] A buffer collection trough includes a basket body, a feeding arm, and a shaft. One end of the basket body is connected to the feeding arm via the shaft, the shaft is fixedly connected to the feeding arm, and the shaft is rotatably connected to the basket body. The basket body has a groove structure in the middle, a buffer platform is fixed to the top of one end of the basket body, and a stop block is fixed to the other end. A buffer rubber layer is fixed on the groove structure. The feeding arm is divided into a deceleration section and a buffer section near the shaft. The deceleration section connects to the buffer section. A deceleration rubber layer is fixed to the upper surface of the deceleration section, and a corrugated rubber layer is provided on the upper surface of the buffer section.
[0007] Furthermore, the feeding arm includes an end cap and a frame, with the end cap and frame fixedly connected to the shaft by bolts.
[0008] Furthermore, the buffer rubber layer transitions smoothly with the lower edge of the buffer platform.
[0009] Furthermore, the position of the stop is higher than that of the buffer platform.
[0010] Furthermore, a buffer rubber block is fixed to the inner side of the stop block.
[0011] Furthermore, the groove structure is arc-shaped.
[0012] Furthermore, a transition surface is formed between the buffer platform and the groove structure, and the angle between the transition surface and the horizontal plane is less than 50°.
[0013] Furthermore, the top surface of the corrugated rubber layer has a wavy or toothed structure.
[0014] Furthermore, the buffer rubber layer is fixedly connected to the basket body by bolts.

[0032] The present invention will now be described in detail with reference to the accompanying drawings. However, it should be noted that the implementation of the present invention is not limited to the following embodiments.
[0033] Example 1
[0034] See Figure 2 , Figure 4 , Figure 5A buffer collection trough includes a basket body 1, a feeding arm 2, and a shaft 6. One end of the basket body 1 is connected to the feeding arm 2 via the shaft 6. The shaft 6 is fixedly connected to the feeding arm 2 and rotatably connected to the basket body 1. The basket body 1 has a groove structure 15 in the middle. A buffer platform 11 is fixed to the top of one end of the basket body 1, and a stop block 13 is fixed to the other end. A buffer rubber layer 12 is fixed on the groove structure 15. The buffer rubber layer 12 can be fixed by strong adhesive or bolts. The bolts can be hexagonal socket head cap screws, which are placed on both sides of the groove structure 15. The top surface of the hexagonal socket head cap screws is embedded in the buffer rubber layer 12 to prevent the rod material 5 from being bumped and affecting the surface quality of the rod material 5. The feeding arm 2 is divided into a deceleration section and a buffer section near the shaft 6. The deceleration section connects to the buffer section. A deceleration rubber layer 23 is fixed to the upper end surface of the deceleration section, and a corrugated rubber layer 24 is provided on the upper surface of the buffer section. The bar 5 first falls onto the deceleration rubber layer 23, where it is decelerated by friction, and then enters the buffer section where it is decelerated a second time by the corrugated rubber layer 24.
[0035] Example 2
[0036] See Figure 6 Based on Example 1, the feed arm 2 includes an end cap 22 and a boom 21, with the end cap 22 and boom 21 fixedly connected to the shaft 6 by bolts. The boom 21 is divided into a deceleration section and a buffer section, with the included angle between the deceleration section and the buffer section being 160° to 215°. The top surface of the corrugated rubber layer 24 has a wavy or toothed structure to facilitate further deceleration of the rod 5.
[0037] Example 3
[0038] See Figure 2 , Figure 4 , Figure 5 The material basket body 1 of the buffer collection trough is connected to the shaft 6 via a bearing seat 7, ensuring relative rotation between the shaft 6 and the material basket body 1. One end of the buffer platform 11 is lower than the centerline of the roller conveyor, the top surface of the middle section is a planar structure, and the other side forms a transition surface 16 with the groove structure 15, with the angle between the transition surface 16 and the horizontal plane being less than 50°. The buffer rubber layer 12 smoothly transitions to the lower edge of the buffer platform 11, allowing the rod 5 to enter the groove structure 15 at a relatively uniform speed. The groove structure 15 is arc-shaped, serving a buffering function. The stop block 13 is positioned higher than the buffer platform 11, preventing the rod 5 from moving out of the material basket body 1 due to inertia. A buffer rubber block 14 (which can be made of rubber) is fixed inside the stop block 13. Its function is to buffer the lateral force when the rod 5 rolls out of the groove structure 15 under the action of inertial force after being pushed into the collection groove, so that the material basket body 1 is subjected to lateral force. This prevents the side wall of the material basket body 1 from being subjected to repeated force by multiple rolling rods 5, which would cause the buffer collection groove foot to break and shift.
[0039] Example 4
[0040] Buffer collection troughs are arranged in rows at the end of the roller conveyor of the conveyor bar 5. The feeding arm 2 is driven by the shaft 6, which can be driven by a motor to rotate, thereby causing the arm 21 to swing. Furthermore, see... Figure 3 The feeding arm 2 can be powered by a pneumatic or hydraulic cylinder 8. At least two feeding arms 2 are equipped with pneumatic or hydraulic cylinders 8 in rows of buffer collection troughs. A support 25 is fixed to the bottom of the feeding arm 2, and the support 25 is hinged to the piston rod of the pneumatic or hydraulic cylinder 8. The cylinder body of the pneumatic or hydraulic cylinder 8 is hinged to the base, which can be fixedly connected to the material basket body 1 or directly fixed to the foundation. When the piston rod of the pneumatic or hydraulic cylinder 8 extends, it drives the feeding arm 2 to rise, feeding the bar 5 into the material basket body 1.
[0041] The working principle of the buffer collection trough: see Figure 9 The feeding arm 2 rotates around point O. Point A, the endpoint of the buffer platform 11, must be lower than the centerline of the roller conveyor to prevent the bar 5 from getting stuck between the feeding arm 2 and the material basket body 1 when the feeding arm 2 feeds the steel. During the lifting process of the feeding arm 2, the bar 5 rolls from a high place to a low place. The deceleration rubber layer 23 on the working surface C forms an angle with the working surface B of the buffer platform, which performs a first-level deceleration on the bar 5. When the feeding arm 2 continues to lift, the bar 5 rolls to the corrugated rubber layer 24. The elasticity of the rubber reduces the kinetic energy of the rolling bar 5, which performs a second-level deceleration on the bar 5. Finally, the bar 5 can pause briefly after rolling to the top plane of the buffer platform. When a certain number of bars 5 have accumulated, the feeding arm 2 continues to lift and feed, so that all the bars 5 enter the groove structure 15 together. In addition, the buffer rubber layer 12 in the groove structure 15 not only decelerates the bars 5 but also reduces the impact force of the bars 5 on the material basket body 1.
[0042] This utility model has a simple and reasonable structure, low equipment modification cost, and can decelerate the material during feeding. The rods are also buffered as they enter the material basket, preventing damage to the basket and its foundation due to impact when the rods fall, thus extending the service life of the collection trough. Rubber layers are provided on the upper surface of the feeding arm and inside the material basket, giving the feeding arm and basket a deceleration function. The rods are decelerated and buffered from the start of feeding, increasing friction. Simultaneously, a corrugated rubber layer is provided in the buffer section of the feeding arm, working in conjunction with the buffer platform to minimize the movement speed of the rods. Furthermore, the transition surface reduces the impact force of the rods entering the groove structure, minimizing damage to the collection trough.

However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
