Description

Technical Field

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

[0002] In many fields such as industrial production, logistics and transportation, and mining, material feeding and conveying is a crucial link, and its efficiency and quality directly affect the smoothness of the entire production process and the quality of products.

[0003] Chinese Utility Model Authorization Announcement No.: CN 223238943 U, a material feeding and conveying device, the buffer device includes an upright, the upright is fixedly installed on the surface of a base plate, a sliding plate is slidably connected to the surface of the upright, a carrying bucket is fixedly installed on the side of the sliding plate, two L-shaped plates are fixedly installed on the surface of the base plate, a sliding rod is fixedly installed between the two L-shaped plates, two movable plates are slidably connected to the surface of the sliding rod, a spring is fixedly installed between the two movable plates, a hinge plate is hinged to the top surface of the movable plates, and a crossbar is fixedly installed on the surface of the carrying bucket away from the sliding plate. This utility model solves the problem that in existing material feeding and conveying devices, the material drop point is subjected to long-term impact from the material on the upstream belt. Although buffer rollers are installed at the material drop point to greatly reduce the impact of the falling material, they cannot prevent damage to the conveyor belt surface. Long-term use will still increase the wear of the conveyor belt and reduce its service life.

[0004] The above equipment works by feeding material from the hopper into the carrying hopper, and then dropping it onto the conveying device through the buffer of the carrying hopper, thus completing the material conveying. However, since the size of the outlet of the carrying hopper is fixed, the size of the material discharged from the outlet cannot be adjusted, making it difficult to adapt to the needs of conveyor belts of different widths. When changing to a conveyor belt of different specifications and widths, it is often necessary to replace the carrying hopper to adapt to the width of the conveyor belt. This not only increases the modification cost and time cost of the equipment, but also limits the versatility and interchangeability of the equipment in different production environments. Utility Model Content

[0005] In view of this, the present invention provides a material feeding and conveying device, which enables the guide plate to guide the material to concentrate in the central area of ​​the conveyor belt, avoiding the material from being too dispersed, and is also adaptable to conveyor belts of different widths.

[0006] To solve the above technical problems, this utility model provides a material feeding and conveying device, including a conveyor belt body and a hopper body. The hopper body is located at one end of the conveyor belt body. The device is characterized by: a buffer hopper inclinedly arranged at the bottom of the hopper body; the discharge end of the buffer hopper located at the top of the conveyor belt body; and a discharge adjustment assembly arranged on the buffer hopper. The discharge adjustment assembly includes a rotating groove one and a rotating groove two respectively arranged on both sides of the inner wall of the buffer hopper. A rotating column one is rotatably arranged in the rotating groove one, and a rotating column two is arranged in the rotating groove two. Guide plates are arranged on both rotating columns one and two. That is, the hopper body acts as a material storage container, relying on gravity to allow the material to continuously flow to the bottom and fall into the buffer hopper. The inclined design of the buffer hopper can reduce the impact of the material on the conveyor belt, reducing the kinetic energy of its direct impact. Subsequently, the material flow direction is controlled by adjusting the angle of the guide plate on the buffer hopper: when the guide plate is at a small angle of 0°-30°, the material naturally disperses, suitable for wide conveyor belts or scenarios requiring low dispersion; if adjusted to 30°... With a large 60° angle, the guide plate forces materials to converge towards the center of the conveyor belt, preventing them from scattering. It can adapt to different conveyor belt widths, ensuring stable and efficient material transport.

[0007] The discharge adjustment assembly also includes a worm gear one and a worm gear two respectively disposed on the bottom of the buffer hopper. The side end of the worm gear one is connected to the end of the rotating column one, and the end of the worm gear two is connected to the end of the rotating column two; thus facilitating the subsequent rotation of the worm gear one or the worm gear two, so that the rotating column one or the rotating column two can rotate.

[0008] The discharge adjustment assembly also includes a mounting base one and a mounting base two respectively disposed at both ends of the bottom of the buffer hopper. A worm gear one is rotatably disposed on the mounting base one and meshes with a worm wheel one. A worm gear two is disposed on the mounting base two and meshes with a worm wheel one. That is, the worm gear one and the worm wheel one have a self-locking function, and the worm gear two and the worm wheel two have a self-locking function.

[0009] The discharge adjustment assembly also includes a plug block disposed on one end of the worm gear, and a slot is provided at one end of the second worm gear, with the plug block located in the slot; thus making the first worm gear and the second worm gear have a unified axis.

[0010] The discharge adjustment assembly also includes a fixing bolt disposed on the outer surface of the second worm gear, the fixing bolt being threaded into the slot and the insert; thus facilitating the assembly of the first and second worm gears, while preventing the insert from dislodging from the slot.

[0011] The discharge adjustment assembly also includes a drive button disposed on the side of the mounting base. The side of the drive button is connected to one end of the worm gear two; that is, the drive button provides drive for the worm gear two, thereby causing the worm gear two to drive the worm gear one to rotate.

[0012] The hopper body is equipped with a lifting device, which is used to lift and support the buffer hopper body; that is, the hopper provides support for the buffer hopper.

[0013] The buffer hopper has a smooth surface, which improves the smoothness of the material feeding process.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The discharge adjustment component adopts a structure consisting of a guide plate, rotating trough one, rotating trough two, rotating column one, and rotating column two. Rotating column one and rotating column two rotate within rotating trough one and rotating trough two, respectively, allowing the guide plate to flexibly adjust its angle within the range of 0° - 60° according to the width of the conveyor belt. When the guide plate is at a small angle of 0° - 30°, the material naturally disperses, which is suitable for wide conveyor belts or scenarios where the material dispersion requirement is low, ensuring that the material fully utilizes the conveyor belt surface and improving conveying efficiency. When the guide plate is adjusted to a large angle of 30° - 60°, the material is forcibly guided to the center area of ​​the conveyor belt, effectively preventing the material from scattering to the edge or outside of the conveyor belt.

[0015] 2. The discharge adjustment component adopts a worm gear transmission structure. Worm gear one and worm one, and worm gear two and worm two are respectively meshed. The rotation directions of worm gear one and worm gear two are opposite. This can adjust the angle of the guide plate. At the same time, the worm gear transmission has a self-locking function, which can automatically lock the position of the guide plate after the adjustment is completed. This effectively prevents the guide plate angle from changing unexpectedly due to equipment vibration or material impact, and ensures the stability and reliability of material guidance.

[0016] 3. The discharge adjustment component uses a worm gear with a plug at one end and a slot at the other end. The plug and slot can be fixed and limited by fixing bolts, which ensures that the first and second worm gears rotate synchronously on the same axis, avoiding loosening during rotation and facilitating the subsequent disassembly of the first and second worm gears.

Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0019] like Figure 1-5 As shown: This embodiment provides a material feeding and conveying device, including a conveyor belt body 100 and a hopper body 101. The hopper body 101 is used to store materials and is located at one end of the conveyor belt body 100. A buffer hopper 102 is inclinedly arranged at the bottom of the hopper body 101. The buffer hopper 102 can guide the material to slide naturally, reducing energy consumption. The discharge end of the buffer hopper 102 is located at the top of the conveyor belt body 100, and the discharge end of the buffer hopper 102 is precisely connected to the top of the conveyor belt, forming a buffer channel for the material to fall, reducing the wear caused by large pieces of material directly impacting the conveyor belt. The upper part is provided with a discharge adjustment component 200, which includes a first rotating groove 202 and a second rotating groove 203 respectively disposed on both sides of the inner wall of the buffer hopper 102. A first rotating column 208 is rotatably disposed in the first rotating groove 202, and a second rotating column 205 is disposed in the second rotating groove 203. A guide plate 201 is provided on both the first rotating column 208 and the second rotating column 205. The guide plate 201 can adjust its angle by rotating the first rotating column 208 and the second rotating column 205, so that the guide plate 201 can guide the material to concentrate in the center area of ​​the conveyor belt, avoid the material being too scattered, and adapt to conveyor belts of different widths. The hopper body 101 serves as a material storage container. Gravity causes the material to flow continuously to the bottom, falling onto the buffer hopper 102. The buffer hopper 102 then uses an inclined angle to transport the material onto the conveyor belt, reducing the kinetic energy of the material directly impacting the conveyor belt. The guide plate 201 on the buffer hopper 102 rotates according to the width of the conveyor belt. When the guide plate rotates at an angle of 0° to 30°, the material flow is less obstructed, which is suitable for scenarios with a wide conveyor belt or low material dispersion requirements. When the guide plate rotates at a large angle of 30° to 60°, the inclination of the guide plate intensifies, guiding the material flow and forcing it to converge towards the center of the conveyor belt, preventing the material from scattering to the edge or outside of the conveyor belt. This achieves symmetrical concentration of the material flow, avoids excessive material dispersion, and adapts to conveyor belts of different widths.

[0020] Worm Gear 1209 Figure 4 As shown, The discharge adjustment assembly 200 also includes a first worm gear 209 and a second worm gear 206 respectively disposed on the bottom of the buffer hopper 102. The side end of the first worm gear 209 is connected to the end of the first rotating column 208, and the end of the second worm gear 206 is connected to the end of the second rotating column 205. The discharge adjustment assembly 200 also includes mounting base one 215 and mounting base two 204 respectively disposed at both ends of the bottom of the buffer hopper 102. Mounting base one 215 and mounting base two 204 are mounted at both ends of the bottom of the buffer hopper 102 by welding. A worm gear one 207 is rotatably mounted on mounting base one 215, meshing with a worm wheel one 209. A worm gear two 213 is disposed on mounting base two 204, meshing with a worm wheel one 209. 13 is mounted on mounting base 1 215 and mounting base 204 respectively via bearings. At the same time, the helical directions of worm gear 1 207 and worm gear 213 are opposite, which facilitates the rotation of worm gear 1 207 and worm gear 213. This causes worm gear 1 207 and worm gear 213 to drive worm wheel 1 209 and worm wheel 206 to rotate, so that the rotation directions of worm wheel 1 209 and worm wheel 206 are opposite. At the same time, worm wheel 1 209 and worm gear 1 207 or worm gear 213 and worm wheel 206 have a self-locking function. Worm Gear 1207 Figure 5 As shown, The discharge adjustment assembly 200 also includes a plug 211 disposed on the end of the worm gear 1 207. The plug 211 is fixedly installed on the worm gear 1 207 by welding. One end of the worm gear 213 is provided with a slot 210. The plug 211 is located in the slot 210 to ensure complete embedding, so that the worm gear 1 207 and the worm gear 213 are on the same axis. The discharge adjustment assembly 200 also includes a fixing bolt 212 disposed on the outer surface of the worm gear 213. The fixing bolt 212 is threadedly connected to the slot 210 and the insert 211, thereby facilitating the fixing and limiting of the slot 210 and the insert 211. First, by rotating the fixing bolt 212, the fixing bolt 212 is inserted into the slot 210 and the insert block 211, thereby limiting the insertion block 211 and the slot 210. This prevents the worm gear 1 207 and the worm gear 213 from loosening during rotation, thus facilitating the subsequent disassembly of the worm gear 1 207 and the worm gear 213.

[0021] Mounting base 1215 Figure 4 As shown, The discharge adjustment assembly 200 also includes a drive button 214 disposed on the side end of the mounting base 215. The side end of the drive button 214 is connected to one end of the worm gear 213. The rotation of the drive button 214 can drive the worm gear 213, so that the worm gear 213 drives the worm gear 207 to rotate. The hopper body 101 is as follows Figure 3 As shown, The hopper body 101 is provided with a lifting component 300. The lifting component 300 is used to lift and support the buffer hopper 102 body. The lifting component 300 can be installed on the hopper body 101 using an existing hook. Then the hook hooks the buffer hopper 102 into the lifting opening. At the same time, the lifting component 300 can also use ropes in the prior art to lift the buffer hopper 102. The interior of the buffer hopper 102 has a smooth surface, which provides flowability for the material inside the buffer hopper 102. Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
