Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, and more specifically, to a cone crusher belt feed belt soil self-cleaning device. In addition, the utility model also relates to a cone crusher including the cone crusher belt feed belt soil self-cleaning device. Background Art

[0002] Cone crushers are widely used in metallurgy, construction, highway, chemical and construction industries. Cone crushers are suitable for crushing ores and rocks with medium to high hardness and high abrasiveness, especially for crushing metal ores and building stones. They are often used as second-stage and third-stage crushers, mainly for medium and fine crushing of ores or rocks.

[0003] The feeding belt is a conveying mechanism connecting the first-stage crusher and the second-stage crusher. It is used to transport sand and gravel from the first-stage crusher to the cone crusher for secondary crushing. The feeding belt usually adopts a belt structure. During the sand and gravel transportation process, the belt will be wetted due to spraying and other reasons, causing a large amount of mud to adhere to the belt. As the belt circulates, the mud will fall on the main crushing motor and main engine oil station under the feeding belt, and accumulate on the main crushing motor and main engine oil station, thereby affecting the heat dissipation and the daily operation and maintenance of the equipment.

[0004] To address this technical issue, related technologies employ a fixed baffle between the feed belt 1 and the motor and oil station, using it to block mud from covering the equipment below. However, due to limitations in transport height and the angle at which the feed belt is arranged, the fixed baffle has no tilt angle, or the tilt angle that can be set is very small. This tilt angle is insufficient to allow mud that falls onto the fixed baffle to slide down automatically, causing mud to accumulate on the fixed baffle, requiring regular manual cleaning. If this is not done promptly, the mud on the fixed baffle will rub against the belt, increasing the power of the feed motor and causing increased belt wear.

[0005] In summary, how to clean the soil on the feeding belt of the cone crusher conveniently and promptly to avoid soil accumulation is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of the utility model is to provide a cone crusher belt feeding belt soil self-cleaning device, which can conveniently and timely clean the cone crusher belt feeding belt soil to avoid soil accumulation.

[0007] Another object of the present invention is to provide a cone crusher comprising the above-mentioned cone crusher belt feeding belt soil self-cleaning device, so that the soil on the feeding belt can be cleaned conveniently and promptly to avoid soil accumulation.

[0008] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0009] A cone crusher belt feeding belt soil self-cleaning device, comprising:

[0010] Feeding belt, with transport state and working state;

[0011] A mudguard is provided below the feeding belt, and the inclination angle of the mudguard is adjustable so that when the feeding belt is in the transport state, the mudguard has a first preset angle, and when the feeding belt is in the working state, the mudguard has a second preset angle, the second preset angle being greater than the first preset angle, and when the mudguard has the second preset angle, the mud on the mudguard can automatically fall off.

[0012] Optionally, an elastic member is connected between the fender and the feeding belt. When the elastic member stretches to a preset length as the amount of mud on the fender increases, the fender has the second preset angle.

The two elastic members in the same group have the same stiffness coefficient, and the two elastic members in different groups and located on the same side of the center line are spaced apart along the tilt direction.

[0015] Optionally, the distance from the elastic member close to the inclined top end of the fender to the inclined top end is smaller than the distance from the elastic member close to the inclined bottom end to the inclined bottom end.

[0016] Optionally, a support is provided at the bottom of the feeding belt, and one end of the elastic member is connected to the support.

[0017] Optionally, a flexible member is connected between the fender and the feeding belt. When the flexible member is tensioned, the fender has the second preset angle. When the flexible member is relaxed, the fender has the first preset angle.

[0019] Optionally, it also includes:

[0020] The spraying device is arranged above the feeding belt of the cone crusher belt feeding belt soil self-cleaning device and is used for removing dust from the material transported on the conveyor belt of the feeding belt.

[0022] The utility model provides a cone crusher belt feed belt soil self-cleaning device. Since the inclination angle of the mudguard is adjustable, the mudguard can be adjusted to adapt to the state of the feed belt by adjusting the inclination angle of the mudguard. When the feed belt is in a transport state, it is limited by the transport height. The position of the feed belt limits the mudguard from having a large inclination angle. Therefore, the inclination angle of the mudguard can be adjusted to a first preset angle at this time, so that the mudguard can adapt to the installation space when the feed belt is in the transport state, avoiding interference between the mudguard and other structural parts of the cone crusher. When the feed belt is in a working state, the space allowed for the mudguard is relatively large. At this time, the mudguard can be made to have a larger inclination angle, for example, the mudguard is made to have a second preset angle, so that the mud that falls on the mudguard during the operation of the feed belt can automatically slide off the mudguard.

[0023] That is to say, the mud guard of the cone crusher belt feeding belt soil self-cleaning device can adjust the inclination angle, which can not only meet the transportation status requirements of the feeding belt, but also enable the mud on the mud guard to slide off automatically. Without human operation, the mud under the feeding belt can be automatically cleaned, avoiding soil accumulation and preventing the mud on the mud guard from rubbing against the belt of the feeding belt, etc., which is conducive to ensuring the stability and reliability of equipment operation and reducing maintenance costs.

DETAILED DESCRIPTION

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] The core of the utility model is to provide a cone crusher belt feed belt soil self-cleaning device, which can conveniently and timely clean the soil on the cone crusher belt feed belt to avoid soil accumulation. Another core of the utility model is to provide a cone crusher including the above-mentioned cone crusher belt feed belt soil self-cleaning device, which can conveniently and timely clean the soil on the feed belt to avoid soil accumulation.

[0032] Please refer to Figure 1 The embodiment of the utility model provides a cone crusher belt feeding belt soil self-cleaning device, which is applied to the cone crusher. The cone crusher belt feeding belt soil self-cleaning device includes a feeding belt 1 and a mudguard 2. The feeding belt 1 has a transport state and a working state. The mudguard 2 is arranged below the feeding belt 1, and the inclination angle of the mudguard 2 is adjustable, so that when the feeding belt 1 is in the transport state, the mudguard 2 has a first preset angle, and when the feeding belt 1 is in the working state, the mudguard 2 has a second preset angle, the second preset angle is greater than the first preset angle, and when the mudguard 2 has the second preset angle, the mud on the mudguard 2 can fall automatically.

[0033] It is understandable that, since the inclination angle of the mudguard 2 is adjustable, the mudguard 2 can be adjusted to adapt to the state of the feed belt 1 by adjusting the inclination angle of the mudguard 2. When the feed belt 1 is in the transport state, it is limited by the transport height, and the position state of the feed belt 1 limits the mudguard 2 from having a larger inclination angle. Therefore, at this time, the inclination angle of the mudguard 2 can be adjusted to a first preset angle so that the mudguard 2 can adapt to the installation space when the feed belt 1 is in the transport state, avoiding interference between the mudguard 2 and other structural parts of the cone crusher; when the feed belt 1 is in the working state, the space allowed for the mudguard 2 is relatively large. At this time, the mudguard 2 can be made to have a larger inclination angle, for example, the mudguard 2 can be made to have a second preset angle, so that the soil falling on the mudguard 2 during the operation of the feed belt 1 can automatically slide off the mudguard 2.

[0034] That is to say, the mudguard 2 in the embodiment of the utility model has an adjustable tilt angle, which can not only meet the transportation status requirements of the feeding belt 1, but also enable the mud on the mudguard 2 to slide off automatically, and automatically clean the mud under the feeding belt 1 without human operation, thereby avoiding mud accumulation and preventing the mud on the mudguard 2 from rubbing against the belt of the feeding belt 1, etc., which is conducive to ensuring the stability and reliability of the equipment operation and reducing maintenance costs.

[0035] It should be noted that this embodiment does not limit the specific implementation method of the adjustable inclination angle of the fender 2, as long as the inclination angle of the fender 2 is adjustable.

[0036] Please refer to Figure 1 and Figure 2 Considering the simplicity of the structure, in some embodiments, an elastic member 3 is connected between the fender 2 and the feeding belt 1. When the elastic member 3 extends to a preset length as the amount of mud on the fender 2 increases, the fender 2 has a second preset angle.

[0037] That is, in this embodiment, the fender 2 is hoisted below the feed belt 1 using the elastic member 3. When there is no dirt on the fender 2, the elastic force of the elastic member 3 is balanced with the gravity of the fender 2. At this time, the fender 2 has a first preset angle. That is, when the fender 2 is in a transport state or even when the fender 2 is in a working state but no dirt has fallen on the fender 2, the fender 2 is at a minimum tilt angle, that is, the first preset angle. When dirt begins to fall on the fender 2, the weight of the fender 2 gradually increases due to the dirt, thereby continuously stretching the elastic member 3, causing the tilt angle of the fender 2 to change. When the tilt angle of the fender 2 reaches a certain value, for example, when the fender 2 is at the second preset angle, the dirt on the fender 2 will automatically slide off the fender 2, achieving the purpose of self-cleaning of the dirt without the need for manual cleaning.

[0038] It should be noted that this embodiment does not limit the number of elastic members 3. The number of elastic members 3 can be one or at least two. When the number of elastic members 3 is one or two, other support points are required to stabilize the fender 2. For example, a rigid member and an elastic member 3 can be used in combination. That is, not only an elastic member 3 but also a rigid member is connected between the fender 2 and the feed belt 1. The rigid member is hinged to the fender 2. In this way, when the weight of the soil on the fender 2 increases and the elastic member 3 stretches, the fender 2 rotates toward the point or axis at which it is hinged to the rigid member, thereby achieving the tilting of the fender 2. Of course, only an elastic member 3 can be connected between the fender 2 and the feed belt 1. In this case, in order to ensure the stability of the position of the fender 2, the number of elastic members 3 is at least three. The tilt angle and tilt direction of the fender 2 are determined by the distribution of the elastic members 3.

[0039] In order to facilitate the inclination of the fender 2 , in some embodiments, the number of the elastic members 3 is at least two, and the elastic member 3 closer to the inclined bottom end 22 of the fender 2 has a lower spring coefficient.

[0040] It should be noted that in the embodiment of the present invention, the inclined bottom end 22 of the fender 2 refers to the lowest point of the fender 2 when tilted, and the inclined top end 21 of the fender 2 refers to the highest point of the fender 2 when tilted. In other words, in this embodiment, the closer the elastic member 3 is to the inclined bottom end 22 of the fender 2, the lower its spring rate. The elastic member 3 closest to the inclined bottom end 22 of the fender 2 has the lowest spring rate. The lower the spring rate of the elastic member 3, the greater the stretching length of the elastic member 3 under the same force. Therefore, this arrangement of the embodiment facilitates tilting of the fender 2.

[0041] Furthermore, in some embodiments, the number of elastic members 3 is four, and each two elastic members 3 form a group. The two elastic members 3 in the same group are symmetrically arranged about the center line of the fender 2 parallel to the tilting direction, and the two elastic members 3 in the same group have the same stiffness coefficient; the two elastic members 3 in different groups and located on the same side of the center line are spaced apart along the tilting direction.

[0042] That is to say, in this embodiment, four elastic members 3 are arranged between the mudguard 2 and the feeding belt 1, and the distances between the two elastic members 3 in the same group and the inclined bottom end 22 of the mudguard 2 are the same, and the stiffness coefficients of the two elastic members 3 in the same group are the same, that is, when the elastic members 3 are extended by the gravity of the soil on the mudguard 2, the extended lengths of the two elastic members 3 in the same group are the same, while the two elastic members 3 in different groups and located on the same side of the center line are spaced apart along the inclined direction. Combined with the above definition that the closer the elastic member 3 is to the inclined bottom end 22 of the mudguard 2, the lower the stiffness coefficient, it can be seen that the stiffness coefficients of the elastic members 3 in different groups are different, and the stiffness coefficient of the elastic member 3 close to the inclined bottom end 22 is smaller than the stiffness coefficient of the elastic members 3 in another group. For example, Figure 2 As shown, the two elastic members 3 in different groups and located on the same side of the above-mentioned center line are respectively referred to as the first elastic member 31 and the second elastic member 32. The first elastic member 31 is close to the inclined top end 21 of the fender 2, and the second elastic member 32 is close to the inclined bottom end 22 of the fender 2. The stiffness coefficient of the first elastic member 31 is greater than the stiffness coefficient of the second elastic member 32. In this way, as the weight of the soil on the fender 2 increases, the elongation of the elastic members 3 in different groups is different, thereby causing the fender 2 to tilt and changing the tilt angle of the fender 2. When the tilt angle reaches a certain value, the soil on the fender 2 will automatically slide down.

[0043] In addition, in some embodiments, the distance between the elastic member 3 near the inclined top end 21 of the fender 2 and the inclined top end 21 is smaller than the distance between the elastic member 3 near the inclined bottom end 22 and the inclined bottom end 22. Figure 2 As shown, the distance from the first elastic member 31 to the inclined top end 21 is smaller than the distance from the second elastic member 32 to the inclined bottom end 22 .

[0044] That is to say, in this embodiment, the elastic member 3 is disposed close to the inclined top end 21 of the fender 2 , so that the fender 2 has a moment of inclination toward the inclined bottom end 22 , which is conducive to the fender 2 having a tendency to incline toward the inclined bottom end 22 .

[0045] In addition, in order to facilitate the connection between the elastic member 3 and the feeding belt 1 , in some embodiments, a support 4 is provided at the bottom of the feeding belt 1 , and one end of the elastic member 3 is connected to the support 4 .

[0046] That is, in this embodiment, the elastic member 3 is connected to the feed belt 1 via the support 4. A rational design of the structure of the support 4 facilitates the connection between the elastic member 3 and the feed belt 1. It should be noted that this embodiment does not limit the specific connection method between the support 4 and the feed belt 1, as long as the connection between the two can be achieved. In some embodiments, the support 4 is welded to the feed belt 1. Furthermore, in some embodiments, the elastic member 3 is hooked to the support 4.

[0047] In addition, the above embodiments do not limit the specific structure of the elastic member 3, as long as the elastic member 3 is elastic. In some embodiments, the elastic member 3 is a spring, which has a simple structure and is easy to implement.

[0048] Of course, in other embodiments, other schemes can be used to adjust the inclination angle of the mudguard 2. For example, in some embodiments, a flexible member is connected between the mudguard 2 and the feeding belt 1. When the flexible member is tensioned, the mudguard 2 has a second preset angle. When the flexible member is relaxed, the mudguard 2 has a first preset angle.

[0049] That is to say, when the feeding belt 1 is in the transport state, the flexible part is in a relaxed state. In this way, when the feeding belt 1 is retracted, due to limited space, the mudguard 2 is supported in a preset position by the action of other structural parts under the feeding belt 1. Since the flexible part is flexible, it can be in any shape when it is in a relaxed state. Therefore, the change in the shape of the flexible part can avoid adapting to the position of the mudguard 2 and avoid interference between the mudguard 2 and other structural parts when the feeding belt 1 is retracted.

[0050] In addition to the above-mentioned cone crusher belt feeding belt soil self-cleaning device, the present invention also provides a cone crusher including the cone crusher belt feeding belt soil self-cleaning device disclosed in the above-mentioned embodiment. For the structure of other parts of the cone crusher, please refer to the relevant technology and will not be repeated here.

[0051] The key point of this embodiment is that the cone crusher belt feeding belt soil self-cleaning device disclosed in any one of the above embodiments has the same beneficial effects as the above cone crusher belt feeding belt soil self-cleaning device.

[0052] In some embodiments, the cone crusher further includes a spraying device 5, which is disposed above the feed belt 1 of the cone crusher's belt feed belt soil self-cleaning device and is used to remove dust from the material transported on the conveyor belt of the feed belt 1.

[0053] That is, in this embodiment, the spray device 5 sprays the upper portion of the conveyor belt of the feed belt 1 to reduce dust and protect the environment. This embodiment does not limit the specific structure of the spray device 5. In some embodiments, the spray device 5 is a spray device for spraying water mist to reduce dust.

[0054] In addition, in some embodiments, the feeding belt 1 is connected to a variable amplitude cylinder 6, the other end of the variable amplitude cylinder 6 is connected to a frame 7, the frame 7 is provided with a main engine motor 8 and a main engine oil station 9, the main engine motor 8 and the main engine oil station 9 are both arranged below the fender 2 of the cone crusher belt feeding belt soil self-cleaning device, and a cone main engine 10 is provided at the end of the frame 7 away from the main engine oil station 9, and the main engine motor 8 is located between the cone main engine 10 and the main engine oil station 9.

[0055] That is, the present embodiment utilizes the variable amplitude oil cylinder 6 to change the position state of the feed belt 1, so that the feed belt 1 has different position states, for example, the feed belt 1 has a transport state and a working state, etc. When the feed belt 1 is in the working state, it can have different working positions. In addition, it can be understood that the mud guard 2 is located between the feed belt 1 and the main motor 8, and between the feed belt 1 and the main oil station 9. In this way, the mud on the conveyor belt of the feed belt 1 falls on the mud guard 2, which can prevent the mud from falling on the main motor 8 and the main oil station 9, thereby avoiding the accumulation of mud on the main motor 8 and the main oil station 9, thereby playing a role in protecting the equipment.

[0056] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

The description of the above examples is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
