Description

Technical Field

[0001] This utility model relates to the field of material guide trough technology, specifically a material guide trough with a buffer baffle. Background Technology

[0002] The guide chute is a key component in the material conveying system. It is usually made of wear-resistant stainless steel plate and forms a closed or semi-closed channel for material flow. It is mainly installed at the drop point of belt conveyors, bucket elevators or vibrating feeders. Its core function is to guide the material to fall smoothly and accurately into the center of the conveyor belt along a predetermined path, avoiding material imbalance, splashing or blockage, thereby improving conveying efficiency and reducing equipment wear.

[0003] After installation, the end of the feed chute closest to the conveyor belt may have a large angle. Therefore, when the material in the feed chute is conveyed onto the conveyor belt, the material flows at a high speed and directly hits the conveyor belt. The impact causes the rebound, which makes the material splash. The conveyor belt will also be subjected to a large impact force. Long-term exposure to high impact force may cause the conveyor belt to crack, damage the skeleton layer, or even belt misalignment, shortening its service life. To address this, we propose a feed chute with a buffer baffle. Utility Model Content

[0004] The purpose of this invention is to provide a feed trough with a buffer baffle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide trough with a buffer baffle, comprising a guide trough body, the surface of which is provided with a buffer structure, the buffer structure including a discharge bin, the discharge bin being fixedly connected to the surface of the guide trough body, a rotating shaft passing through the surface of the discharge bin, a baffle body being fixedly connected to the arc surface of the rotating shaft, driven wheels being fixedly connected to both ends of the rotating shaft, a threaded rod being rotatably connected to the surface of the discharge bin, a support arm being threadedly connected to the surface of the threaded rod, limit rings being fixedly connected to both ends of the support arm, a transmission rod being inserted into the inner wall of the two limit rings, a drive wheel being fixedly connected to both ends of the transmission rod, and a belt being fitted onto the surface of the drive wheel and the driven wheel.

[0006] The effect achieved by the above components is as follows: by setting up a buffer structure, the baffle body will rotate with the impact force of the material. At this time, the rotation of the baffle body will flip and discharge the material from the other end of the feeding bin. The belt will increase the friction when the driven wheel rotates, thereby buffering the impact force when the material is fed into the guide chute.

[0007] Preferably, the surface of the support arm has two guide rods that slide through it, and the guide rods are fixedly connected to the surface of the feeding bin.

[0008] The effect achieved by the above components is that the guide rod restricts the rotation of the support arm when it moves, thus maintaining its smooth movement and preventing deviation.

[0009] Preferably, a turntable is fixedly connected to the end of the threaded rod away from the feeding bin, and the vertical cross-section of the turntable is in the shape of a cross.

[0010] The effect achieved by the above components is that the rotation of the turntable will drive the threaded rod to rotate, and the turntable facilitates the rotation of the threaded rod.

[0011] Preferably, the surfaces of the driven wheel and the transmission wheel are covered with protective covers, and the transmission rod passes through the protective covers.

[0012] The effect achieved by the above components is that the protective cover covers the driven wheel and the drive wheel, preventing the belt drive components from being exposed, and improving the safety and dustproof performance of the equipment.

[0013] Preferably, a number of ribs are fixedly connected to the surface of the baffle body.

[0014] The effect achieved by the above components is that the ribs fixed to the surface of the baffle body enhance its structural strength and prevent deformation from long-term material impact.

[0015] Preferably, the arc surface of the guide rod is fixedly connected to two limiting plates, and the two limiting plates are respectively attached to the sides of the two limiting rings that are far apart from each other.

[0016] The effect achieved by the above components is that the limiting plate fixed on the arc surface of the transmission rod fits against both sides of the limiting ring, preventing the transmission rod from moving axially and ensuring transmission stability.

[0017] Preferably, a guide plate is fixedly connected to the inner wall of the feeding hopper, and the guide plate is arc-shaped.

[0018] The effect achieved by the above components is that the material will fall into the feeding hopper, and the arc-shaped guide plate on the inner wall of the feeding hopper will guide the material to fall along the arc-shaped path, initially reducing the vertical impact force of the material and causing the material to flow in a concentrated manner towards the baffle body area.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model, by setting a buffer structure, achieves the effect that the baffle body will rotate with the impact force of the material. At this time, the rotation of the baffle body will flip and discharge the material from the other end of the feeding bin. The belt increases the friction force when the driven wheel rotates, thereby buffering the impact force of the material during feeding. By rotating the threaded rod, the tension of the belt can be adjusted, thereby adjusting the friction force when the baffle body rotates, and thus adjusting the buffering efficiency of the baffle body on the material.

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-2This utility model provides a technical solution: a guide trough with a buffer baffle, including a guide trough body 1, a buffer structure 2 on the surface of the guide trough body 1, the buffer structure 2 including a discharge bin 201, the discharge bin 201 being fixedly connected to the surface of the guide trough body 1, a rotating shaft 202 rotatably passing through the surface of the discharge bin 201, a baffle body 203 fixedly connected to the arc surface of the rotating shaft 202, driven wheels 204 fixedly connected to both ends of the rotating shaft 202, a threaded rod 205 rotatably connected to the surface of the discharge bin 201, and a support arm 206 threadedly connected to the surface of the threaded rod 205 for support. Both ends of the arm 206 are fixedly connected to limit rings 207. The inner walls of the two limit rings 207 are inserted with guide rods 208. Both ends of the guide rods 208 are fixedly connected to drive wheels 209. The surfaces of the drive wheels 209 and the driven wheels 204 are covered with belts 210. By setting the buffer structure 2, the baffle body 203 will rotate with the impact force of the material. At this time, the rotation of the baffle body 203 will flip and discharge the material from the other end of the discharge bin 201. The belt 210 will increase the friction force when the driven wheel 204 rotates, thereby buffering the impact force when the material is discharged using the guide chute body 1.

[0030] Reference Figure 3-6 As shown in this embodiment: Two guide rods 211 slide through the surface of the support arm 206. The guide rods 211 are fixedly connected to the surface of the feeding bin 201. The guide rods 211 limit the rotation of the support arm 206 during movement, ensuring stable movement and preventing deviation. A turntable 212 is fixedly connected to the end of the threaded rod 205 away from the feeding bin 201. The vertical cross-section of the turntable 212 is cross-shaped. Rotation of the turntable 212 will drive the threaded rod 205 to rotate, facilitating the rotation of the threaded rod 205. A protective cover 213 covers the surfaces of the driven wheel 204 and the drive wheel. The transmission rod 208 passes through the protective cover 213, which covers the driven wheel 204 and the drive wheel 209, preventing the belt 210 transmission components from being exposed and improving equipment safety and dustproof performance. Several ribs 214 are fixedly connected to the surface of the baffle body 203. The ribs 214 fixed to the surface of the baffle body 203 enhance its structural strength and prevent deformation from long-term material impact. Two limiting plates 215 are fixedly connected to the arc surface of the transmission rod 208. The two limiting plates 215 are respectively attached to the two limiting rings 207 on the opposite sides. The limiting plates 215 fixed to the arc surface of the transmission rod 208 are attached to both sides of the limiting rings 207 to prevent the transmission rod 208 from moving axially and to ensure transmission stability. A guide plate 216 is fixedly connected to the inner wall of the feeding bin 201. The guide plate 216 is arc-shaped. The material will fall into the feeding bin 201. The arc-shaped guide plate 216 on the inner wall of the feeding bin 201 guides the material to fall along the arc path, initially reducing the vertical impact force of the material and causing the material to flow to the area of ​​the baffle body 203.

[0031] Working principle: The operator rotates the turntable 212, which has a cross-shaped vertical cross section, causing the threaded rod 205, which is rotatably connected to the feeding bin 201, to rotate. When the threaded rod 205 rotates, the support arm 206, which is threaded to it, moves upward along the axis of the threaded rod 205. At the same time, the guide rod 211, which slides through the surface, maintains the stability of the movement and avoids deviation. When the support arm 206 moves, the limiting rings 207 at both ends drive the transmission rod 208 inserted therein to move synchronously. The limiting plate 2, which is fixed on the arc surface of the transmission rod 208, moves synchronously. 15. The two sides of the limiting ring 207 are fitted to prevent the axial movement of the transmission rod 208 and ensure transmission stability. The drive wheels 209 at both ends of the transmission rod 208 are connected to the driven wheels 204 at both ends of the rotating shaft 202 through the belt 210 to form a transmission system. The movement of the transmission rod 208 will drive the two drive wheels 209 to move away from the discharge bin 201. The movement of the drive wheels 209 will cause the belt 210 to gradually stretch, thereby increasing the friction between the belt 210 and the transmission wheel and drive wheel 209, thereby increasing the friction of the baffle body 2. The driving force required for rotation is as follows: When the material is fed into the feeding hopper using the guide chute, it falls into the feeding hopper 201. The arc-shaped guide plate 216 on the inner wall of the feeding hopper 201 guides the material to fall along the arc-shaped path, initially reducing the vertical impact force of the material and causing the material to flow towards the baffle body 203 area. The baffle body 203 rotates due to the impact force of the material. At this time, the rotation of the baffle body 203 will cause the material to be discharged from the other end of the feeding hopper 201. The belt 210 will increase the rotation of the driven wheel 204. The friction force during material feeding is adjusted to buffer the impact force of the material. The tension of the belt 210 is adjusted by rotating the threaded rod 205, thereby adjusting the friction force when the baffle body 203 rotates, and thus adjusting the buffering efficiency of the baffle body 203 on the material. The ribs 214 fixed on the surface of the baffle body 203 enhance its structural strength and prevent deformation due to long-term material impact. The protective cover 213 covers the driven wheel 204 and the drive wheel 209 to prevent the belt 210 transmission components from being exposed, thereby improving the safety and dustproof performance of the equipment.
