Description

Technical Field

[0001] The utility model relates to the field of bucket wheel machines, in particular to a chute structure of a bucket wheel machine. Background Art

[0002] A chute is a slot on the ground that is used to transport things from a high place to a low place. The inner surface is smooth and things can slide down automatically (such as a ore flow chute for washing gold ore or an inclined water chute for discharging logs). The chute structure of an existing bucket wheel machine usually has only one inclined section, which directly dumps the material onto the belt conveyor. This can easily lead to the bucket wheel machine belt being easily scattered when stacking and taking material blocks, and the material spills into the non-working surface of the belt, causing small holes and tears. The machine often needs to be shut down for maintenance to fill the holes, resulting in increased hole filling costs. Over time, if the belt is torn too much, it will take a long time to replace the belt, reducing the throughput of the cantilever belt, seriously affecting the production rhythm, and increasing the equipment maintenance cost. Utility Model Content

[0003] The purpose of the utility model is to solve the above technical problems and to provide a segmented chute structure which can adjust the flow of materials in the chute and make the materials in the chute fall to the center of the belt conveyor to prevent material from being scattered.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A chute structure of a bucket wheel excavator comprises an inclined section, a vertical section and a narrowing section connected in sequence, the inclined section is composed of an inclined plate and a first baffle connected to both ends of the inclined plate, the vertical section is perpendicular to a belt conveyor corresponding to the bottom of the narrowing section, the vertical section is surrounded by four lining plates, the narrowing section is perpendicular to the belt conveyor corresponding to the bottom, and the narrowing section is surrounded by four inwardly inclined lining plates to form a shape that is wide at the top and narrow at the bottom.

[0006] In order to be able to control the flow rate of the chute, a further preferred technical solution is that the inclined section is rotatably connected to the vertical section via a rotating shaft, at least one group of relatively arranged cylinder push rods are hinged at the bottom of the inclined section, and the two cylinder push rods are hinged at both sides of the bottom of the inclined plate along the width direction, and a group of relatively arranged cylinder push rods are uniformly controlled by a controller.

[0007] In order to reduce the impact force of the material in the chute on the surface of the belt conveyor, a further preferred technical solution is that a second baffle is provided on both sides of the vertical section, the second baffle is rotatably connected to the lining plate, a spring is connected to the bottom of the second baffle, and the other end of the spring is connected to the lining plate and is arranged at an angle.

[0008] In order to prevent material blockage in the vertical section, a further preferred technical solution is that the initial state of the second baffle is an inclined state.

[0009] In order to prevent excessive dust at the discharge port, a further preferred technical solution is that a dust removal device is provided at the bottom of the vertical section, and the dust removal device includes a nozzle arranged in the vertical section, and the nozzle is connected to a water tank arranged outside the vertical section through a water pipe, and a water pump is provided between the water pipe and the water tank.

[0010] In order to adapt to different belt conveyors and prevent material from spilling out of the chute, a further preferred technical solution is that each of the inclined lining plate surfaces is rotatably connected to a third baffle plate, a rotating shaft rotatably connected to the third baffle plate is arranged at the discharge port of the inclined section, a hanging ring is arranged at the end of the third baffle plate facing away from the rotating shaft, and a hook adapted to the hanging ring is provided on the surface of the inclined lining plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model sets a segmented chute structure, first transports the material from the initial inclined section, then concentrates it in the vertical section for transition connection, and finally concentrates the material dropping at the middle drop point of the belt conveyor through the narrowed section, so as to prevent the problem of material spillage. In addition, the problem of material spillage is usually caused by too fast a dropping speed and a large dropping flow rate. Therefore, an oil cylinder is set in the inclined section, and the flow rate and speed of the material transport are controlled by adjusting the inclination angle of the inclined section, and a baffle is set in the vertical section to buffer the dropping material, so as to reduce the impact force on the belt at the dropping point. The two work together to prevent the belt from being damaged, reduce the maintenance cost of the belt conveyor, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0015] like Figure 1As shown, a chute structure of a bucket wheel excavator includes an inclined section 1, a vertical section 3 and a narrowing section 5 connected in sequence. The inclined section 1 is composed of an inclined plate and a first baffle 2 connected to both ends of the inclined plate, and the connection method is a fixed connection. The vertical section 3 is perpendicular to a belt conveyor 1 corresponding to the bottom of the narrowing section 5. Specifically, a blanking port of the narrowing section 5 is aligned with the center of the belt of the belt conveyor. The vertical section 3 is surrounded by four lining plates 4, which are opened at the top and the bottom respectively. The narrowing section 5 is perpendicular to the belt conveyor 7 corresponding to the bottom. The narrowing section 5 is surrounded by four inwardly inclined lining plates 6 to form a shape that is wide at the top and narrow at the bottom, that is, a funnel shape.

[0016] In order to be able to control the flow of the chute, a further preferred technical solution is that the inclined section 1 is rotatably connected to the vertical section 3 by a rotating shaft 9, and at least one group of relatively arranged cylinder push rods 8 are hinged at the bottom of the inclined section 1. In the present embodiment, one group is hinged, and the reason for the relative arrangement is to ensure the stability of the inclined section 1. The two cylinder push rods 8 are hinged on both sides of the bottom of the inclined plate along the width direction. A group of relatively arranged cylinder push rods 8 are uniformly controlled by the controller to lift and lower the cylinder push rods synchronously, and the flow of the material is adjusted by lifting and lowering the cylinder push rods. When the material flow rate is too fast, the cylinder push rod can be lowered to slow down the slope of the inclined section, and the flow of the material will be slowly reduced. When the material flow is too slow, the slope of the inclined section can be increased to increase the flow.

[0017] In order to reduce the impact force of the material in the chute on the surface of the belt conveyor, a further preferred technical solution is that a second baffle 10 is provided on both sides of the vertical section 3, the second baffle 10 is rotatably connected to the lining plate 4, a spring 11 is connected to the bottom of the second baffle 10, and the other end of the spring 11 is connected to the lining plate 4, and is arranged in an inclined manner. Specifically, in order to prevent material blockage in the vertical section 3, a further preferred technical solution is that the initial state of the second baffle 10 is an inclined state. Since the material in the vertical section is a free fall body, its falling speed is fast, which is easy to cause impact on the surface of the belt conveyor, causing damage to the belt, so the second baffle is set to play a buffering role in the process of descent, and the falling material will be affected by the elastic force transmitted to the second baffle by the spring, thereby reducing its impact force. In addition, the initial state of the second baffle is an inclined state to prevent the material from concentrating on the baffle outlet and causing material blockage. Even if the weight of the accumulated material is greater than the elastic force and the baffle is opened, the accumulated material suddenly falls and causes an impact on the surface of the belt conveyor.

[0018] In order to prevent excessive dust at the discharge port, a further preferred technical solution is that a dust removal device is provided at the bottom of the vertical section 3, and the dust removal device includes a nozzle 12 arranged in the vertical section 3, and the nozzle 12 is connected to a water tank 14 arranged outside the vertical section through a water pipe 13, and a water pump 15 is provided between the water pipe 13 and the water tank 14. Since the material is subject to the elastic force of the baffle, it is easy to cause excessive dust. Therefore, a dust removal device is provided at the outlet to appropriately reduce the dust of the material and prevent excessive dust in the on-site working environment, which will affect the health of the workers. The water tank here can also be replaced with any water supply equipment, such as a faucet, etc., and the utility model does not make too many restrictions.

[0019] In order to adapt to different belt conveyors and prevent material from spilling from the chute, a further preferred technical solution is that each inclined lining plate 6 is rotatably connected to the surface of a third baffle plate 16, and a rotating shaft rotatably connected to the third baffle plate 16 is arranged at the discharge port of the inclined section 5. A hanging ring is arranged at the end of the third baffle plate 16 away from the rotating shaft, and a hook matched with the hanging ring is arranged on the surface of the inclined lining plate 6. Since the height of the device is fixed when it is manufactured, it is easy to cause material spilling due to the discharge port being too high for different belt conveyor heights. Therefore, a third baffle plate is arranged. When the discharge port is too high, the third baffle plate is opened as a supplement to the discharge port, and the baffle plate is used to block the material that is about to be spilled. When the discharge port is just right, the hook can be used to retract it.

[0020] The utility model sets a segmented chute structure, first transports materials from the initial inclined section, then concentrates them in the vertical section for transition connection, and finally concentrates the materials at the middle drop point of the belt conveyor through the narrowed section, so as to prevent the problem of material scattering. In addition, the problem of material scattering is usually caused by too fast drop speed and large drop flow rate. Therefore, an oil cylinder is set in the inclined section, and the flow rate and speed of the material transport are controlled by adjusting the inclination angle of the inclined section, and a baffle is set in the vertical section to buffer the drop, so as to reduce the impact force on the belt at the drop point. The two work together to prevent the belt from being damaged, reduce the maintenance cost of the belt conveyor, and improve production efficiency.

[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
