Description

Technical Field

[0001] The present invention relates to the field of transfer machines, and in particular to a new type of lightweight scraper transfer machine. Background Art

[0002] A scraper transfer machine is a mechanical device for continuously transporting materials. It belongs to a special type or application form of a scraper conveyor. Usually, it is used in industries such as mining and building materials production in supporting with mining equipment, playing the role of material transfer and long-distance transportation, and transferring the materials mined by the mining equipment to the subsequent transportation equipment. A scraper transfer machine is a construction engineering mechanical device, usually used for earthwork in mines and construction projects. It uses a large boom system equipped with a rotatable bucket to collect, transport and unload materials such as earth and stone from the materials excavated underground. This machine is mainly used to quickly move a large amount of materials and improve efficiency during excavation and heavy loading.

[0003] It is developed from new types of raw materials such as carbon fiber and ultra-high molecular weight polyethylene researched, developed and manufactured by the company, non-toxic, odorless, flame-retardant, antistatic, wear-resistant, corrosion-resistant, high-strength and anti-aging.

[0004] The non-metallic middle trough of the scraper conveyor is made of ultra-high molecular weight polyethylene, which is an updated product replacing the traditional steel scraper transfer machine and can be widely used in many fields such as coal, power plants, coal preparation, transportation, building materials, ships and automobile shells and accessories industries.

[0005] After retrieval, the patent publication number is CN212831350U, which discloses a scraper transfer machine, relating to the technical field of mining machinery. The scraper transfer machine includes a scraper transfer machine body and a control unit, and also includes a material pushing device and a surface topography acquisition device for acquiring the shape and motion state of the material. The material pushing device includes a pushing plate that moves linearly driven by a driving mechanism. The driving mechanism and the surface topography acquisition device are both arranged at the tail of the scraper transfer machine body, and the driving mechanism and the surface topography acquisition device are respectively electrically connected to the control unit; the pushing plate is arranged on the driving mechanism. The scraper transfer machine of the present invention solves the problem of material jamming at the tail and improves the working efficiency.

[0006] In the existing technology, although a certain transfer and transportation effect can be achieved during use, the defect is that the existing scraper transfer machine lacks the function of adjusting the movement trajectory, resulting in the inability to achieve the transportation with a lifting effect under some special transportation conditions, making the coal mine work unable to proceed smoothly and effectively. In view of this, we propose a new type of lightweight scraper transfer machine to solve the above problems. Summary of the Invention

[0007] The object of the present invention is directed to the background art, where although a certain transfer and conveying effect can be achieved during use, there are defects: the existing scraper conveyor lacks the function of adjusting the movement trajectory, resulting in the inability to achieve conveying with a lifting effect under some special transportation conditions, making the coal mine work unable to proceed smoothly and effectively. In view of this, we propose a problem of a new type of light scraper conveyor and propose a new type of light scraper conveyor.

[0008] The technical solution of the present invention: A new type of light scraper conveyor, including mounting frame one, mounting frame two, a drum, and a connecting rod. Guide wheels are rotatably installed at the upper ends of the mounting frame one and the mounting frame two. A groove is provided on one side of the mounting frame one. An elevating plate is arranged inside the groove. The drums are rotatably installed between the elevating plates through a rotating shaft. A hydraulic cylinder is fixed at the lower end of the mounting frame two. A hydraulic rod is inserted into the hydraulic cylinder. The hydraulic rod is fixedly connected to one side of the mounting frame one. A connecting rod is rotatably installed between the mounting frame one and the mounting frame two;

[0009] When this device is in use, an external chain can be installed on the upper end of the guide wheel in cooperation with the connecting seat fixed on the surface of the chain. The chain is driven by the protrusion, so that the connecting seat with a scraper moves circularly on the surfaces of the mounting frame one and the mounting frame two to achieve the conveying effect. This device can adjust the distance between the mounting frame one and the mounting frame two by using the hydraulic cylinder. When the distance is increased, the lifting block will move downward under the action of the connecting rod, and the drum will descend, and the chain on the surface will be in a parallel state, and the trajectory of the conveyed object is also a straight line. When the distance between the mounting frame one and the mounting frame two becomes smaller, the connecting rod will drive the drum to move upward, making the movement trajectory of the chain in a triangular state. The baffle will be lifted upward by a certain distance and then descend under the drive of the chain, so as to achieve the convenient switching effect of material conveying in different states, and has high practicability.

[0010] Preferably, brackets are fixed at the lower ends of the mounting frame one and the mounting frame two, and a base is fixed at the lower ends of the brackets.

[0011] Preferably, an installation groove is provided on one side of the mounting frame two. A moving block is slidably inserted at the bottom of the installation groove. A fixing frame two is fixed on the outer wall of one side of the moving block. The connecting rod is rotatably installed between the fixing frame two.

[0012] Preferably, a mounting seat is inserted into the groove. The elevating plate is fixed at the upper end of the mounting seat. A limiting block is fixed at the top of the groove. The width of the mounting seat is equal to the width of the groove. The width of the elevating plate is equal to the distance between the limiting blocks.

[0013] Preferably, a fixing frame one is fixed on the outer wall of one side of the mounting seat. The connecting rod is rotatably installed between the fixing frame one. When the mounting seat is located at the bottom of the groove, the connecting rod is in a state of inclining at an angle of thirty degrees.

[0014] Preferably, a convex portion is provided in the middle of the guide wheel and is distributed in an annular array. A motor is fixed to an outer wall of one side of the second mounting bracket, and an output shaft of the motor is fixedly connected to a rotation center of one side of the guide wheel.

[0015] Preferably, a fixing block is fixed in the middle of the first mounting bracket and the second mounting bracket, and the upper and lower surfaces of the fixing block do not exceed the upper and lower vertices of the guide wheel.

[0016] Preferably, the base is connected between the bracket and the first mounting bracket, and the number of bases is multiple and they are parallel to each other.

[0017] Preferably, the connecting rod is connected between the second fixing bracket and the moving block, and the second fixing brackets are respectively arranged on both sides of the connecting rod and are symmetrically arranged with respect to the vertical center line of the connecting rod.

[0018] Preferably, the convex portion is connected between the guide wheel and the second mounting bracket, and the number of guide wheels is multiple and the guide wheels are arranged to surround the convex portion as the center point.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] First, the present invention can use the hydraulic cylinder to adjust the distance between the first mounting bracket and the second mounting bracket. When the distance is widened, the roller moves downward, and the movement trajectory of the external chain is a parallel straight line. When the distance is narrowed, the roller moves upward, and the movement trajectory of the external chain is triangular.

[0021] Second, based on the first beneficial effect, when the distance between the first mounting bracket and the second mounting bracket is reduced, the chain will be slack. Therefore, it is necessary to cooperate with the upward movement of the roller to achieve the effect of tightening the chain and ensure the stable conveying of the device.

[0022] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0035] Embodiment 1

[0036] Please refer to Figures 1 - 6 As shown, this embodiment is a new type of lightweight scraper conveyor, including a first mounting frame 1, a second mounting frame 6, a roller 8 and a connecting rod 12. Guide wheels 9 are rotatably mounted at the upper ends of the first mounting frame 1 and the second mounting frame 6. A groove 14 is provided on one side of the first mounting frame 1. A lifting plate 13 is provided inside the groove 14. A roller 8 is rotatably mounted between the lifting plates 13 through a rotating shaft 19. A hydraulic cylinder 5 is fixed at the lower end of the second mounting frame 6. A hydraulic rod 4 is inserted into the hydraulic cylinder 5. The hydraulic rod 4 is fixedly connected to one side of the first mounting frame 1. A connecting rod 12 is rotatably mounted between the first mounting frame 1 and the second mounting frame 6;

[0037] When this device is in use, an external chain can be installed on the upper end of the guide wheel 9 in cooperation with the connecting seat fixed on the surface of the chain. The chain is driven by the protrusion 10, so that the connecting seat with the scraper moves circularly on the surfaces of the first mounting frame 1 and the second mounting frame 6, realizing the conveying effect. This device can adjust the distance between the first mounting frame 1 and the second mounting frame 6 by using the hydraulic cylinder 5. When the distance is increased, the lifting block will move downward under the action of the connecting rod 12, and the roller 8 will descend, and the chain on the surface will be in a parallel state, and the trajectory of the conveyed object is also a straight line. When the distance between the first mounting frame 1 and the second mounting frame 6 becomes smaller, the connecting rod 12 will drive the roller 8 to move upward, making the movement trajectory of the chain in a triangular state. The baffle will be lifted upward by a certain distance and then descend under the drive of the chain, so as to realize the convenient switching effect of material conveying in different states, and has high practicability.

[0038] Embodiment 2

[0039] Please refer to Figures 1 - 6 As shown, this embodiment further includes: brackets 2 are fixed at the lower ends of the first mounting frame 1 and the second mounting frame 6, and a base 3 is fixed at the lower ends of the brackets 2. The brackets 2 and the base 3 can increase the stability of the first mounting frame 1 and the second mounting frame 6 and reduce the spread of noise to a certain extent.

[0040] An installation groove 16 is provided on one side of the second mounting frame 6. A moving block 17 is slidably inserted at the bottom of the installation groove 16. A fixing agent two 18 is fixed on the outer wall of one side of the moving block 17. The connecting rod 12 is rotatably installed between the fixing agent two 18. A top block is provided at the bottom of the outer edge of the installation groove 16. The top block can prevent the moving block 17 from sliding out of the inside of the installation groove 16 when sliding along the bottom of the installation groove 16.

[0041] An installation seat 20 is inserted into the groove 14. A lifting plate 13 is fixed at the upper end of the installation seat 20. A limiting block 21 is fixed at the top of the groove 14. The width of the installation seat 20 is equal to the width of the groove 14, and the width of the lifting plate 13 is equal to the distance between the limiting blocks 21. When the installation seat 20 moves upward to the top, its position will be limited by the limiting block 21 so that it will not move out of the groove 14, but the lifting plate 13 can pass through the distance between the limiting blocks 21, which is convenient for realizing the up and down movement effect of the roller 8. The up and down movement of the roller 8 in cooperation with the distance adjustment between the first mounting frame 1 and the second mounting frame 6 can ensure that the external chain between the guide wheels 9 can be kept in a tightened state, ensuring the stability of its conveying.

[0042] A fixing frame 15 is fixed to the outer wall of one side of the mounting seat 20, and a connecting rod 12 is rotatably installed between the fixing frames 15. When the mounting seat 20 is located at the bottom of the groove 14, the connecting rod 12 is inclined at a thirty-degree angle. The thirty-degree angle of the connecting rod 12 is the angle when the distance between the mounting frame 1 and the mounting frame 2 6 is the longest. Subsequently, as long as the distance between the mounting frame 1 and the mounting frame 2 6 is shortened, one end of the connecting rod 12 will move upward under the condition of mutual squeezing, and the problem of movement locking of the connecting rod 12 when it is in a horizontal state will not occur.

[0043] A protrusion 10 distributed in a circular array is provided in the middle of the guide wheel 9, and a motor 11 is fixed to the outer wall of one side of the mounting frame 6. The output shaft of the motor 11 is fixedly connected to the rotation center of one side of the guide wheel 9. The motor 11 can drive the guide wheel 9 to rotate, thereby driving the guide wheel 9 to drive the external chain and the baffle fixed on the surface of the chain to move.

[0044] A fixing block 7 is fixed in the middle of the mounting frame 1 and the mounting frame 2 6. The upper and lower surfaces of the fixing block 7 do not exceed the upper and lower vertices of the guide wheel 9. The fixing block 7 can ensure that when conveying large objects, it has a certain bearing and lifting effect to prevent the chain from deforming and seriously affecting the conveying effect.

[0045] The base 3 is connected between the bracket 2 and the mounting frame 1, and the base 3 is multiple and parallel to each other. The base 3 is multiple and parallel to each other, which can stably place the bracket 2 and the mounting frame 1.

[0046] The connecting rod 12 is connected to the moving block 17 through the fixing frame 18, and the fixing frame 18 is respectively arranged on both sides of the connecting rod 12, and the fixing frame 18 is symmetrically arranged with the vertical midline of the connecting rod 12 as the symmetry axis. The fixing frame 18 symmetrically arranged with the vertical midline of the connecting rod 12 as the symmetry axis can facilitate the user to connect the connecting rod 12 and the moving block 17.

[0047] The protrusion 10 is connected between the guide wheel 9 and the mounting frame 6, and there are multiple guide wheels 9, and the guide wheels 9 are arranged around the protrusion 10 as the center point. The guide wheels 9 arranged around the protrusion 10 as the center point can facilitate users to use the storage and transmission efficiently.

[0048] Working principle: When the user needs to use the device, an external chain needs to be installed on the upper end of the guide wheel 9 in cooperation with the connecting seat fixed on the surface of the chain. The chain is driven by the protrusion 10, so that the connecting seat with a scraper moves circularly on the surfaces of the first mounting frame 1 and the second mounting frame 6 to achieve the conveying effect. This device can adjust the distance between the first mounting frame 1 and the second mounting frame 6 by using the hydraulic cylinder 5. When the distance is increased, the lifting block will move downward under the action of the connecting rod 12, and the roller 8 will descend, and the chain on the surface will be in a parallel state, and the trajectory of the conveyed object is also a straight line. When the distance between the first mounting frame 1 and the second mounting frame 6 becomes smaller, the connecting rod 12 will drive the roller 8 to move upward, so that the movement trajectory of the chain presents a triangular state. The baffle will be lifted upward by a certain distance and then descend under the drive of the chain, so as to achieve the convenient switching effect of material conveying in different states, and has high practicability.
