[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Combine the following Figures 1 to 5 The crusher of the utility model is described.

[0039] like Figures 1 to 5 As shown, the crusher provided by the embodiment of the utility model includes a crusher body 1, a baffle 4 and a first driving member 5.

[0040] Specifically, the crusher body 1 has a crushing bin 2 and a feed port 3, and the feed port 3 is used to supply materials into the crushing bin 2. A feeding device 8 is provided next to the crusher, and the direction in which the feeding device 8 conveys materials is called the feeding direction of the feeding device 8. The end of the feeding device 8 close to the crusher is the feeding end of the feeding device 8. When the feeding device 8 is running, the materials on the feeding device 8 gradually move toward the feeding end. The feeding end of the feeding device 8 is docked with the feed port 3 of the crusher, and the materials on the feeding device 8 are conveyed to the feeding end and enter the crushing bin 2 through the feed port 3.

[0041] The baffle 4 is arranged at the feed port 3, the first end of the baffle 4 is rotatably connected to the crusher body 1, and the second end of the baffle 4 is a free end. The first driving member 5 is arranged on the crusher body 1, and the first driving member 5 is used to drive the baffle 4 to rotate relative to the crusher body 1.

[0042] The first driving member 5 can be, but is not limited to, an electric motor or a hydraulic motor.

[0043] The baffle 4 can rotate between an open position and a closed position. When the baffle 4 rotates to the open position, the feed port 3 is open, and the material can be transported into the crushing bin 2. When the baffle 4 rotates to the closed position, the baffle 4 closes the feed port 3, and the baffle 4 can prevent the material from entering the crushing bin 2.

[0044] With such arrangement, when it is necessary to stop feeding into the crushing bin 2, the baffle 4 can be rotated to the closed position, the feeding device 8 continues to run or slows down, the material on the feeding device 8 continues to approach the feed port 3, and the baffle 4 blocks the material on the feeding device 8 from entering the crushing bin 2, while the material gathers at the feeding end of the feeding device 8. When it is necessary to feed into the crushing bin 2, the baffle 4 is rotated to the open position, and the material gathered at the feeding end of the feeding device 8 can enter the crushing bin 2 in a timely and rapid manner, and the amount of material in the crushing bin 2 is quickly replenished, which solves the problem in the prior art that the material cannot be replenished into the crusher in a timely and rapid manner when the feeding situation of the crusher is controlled by controlling the operation of the feeding device, and is conducive to improving production efficiency and production rhythm.

[0045] In the embodiment of the utility model, the crusher further comprises a material level detection element 6 and a control device.

[0046] The material level detection element 6 is arranged inside the crusher body 1 , and the material level height in the crushing bin 2 can be detected by the material level detection element 6 .

[0047] The material level detection element 6 and the first drive member 5 are both electrically connected to the control device. The control device can control the operation of the first drive member 5 at least according to the material level height in the crushing bin 2 to adjust the position of the baffle 4. The control process is more intuitive, avoiding reference to the working current of the crusher body, and can make the control process more timely.

[0048] During the operation of the crusher body 1, the material level detection element 6 can detect the material level in the crushing bin 2 in real time. When the material level in the crushing bin 2 is less than a preset value, the baffle 4 can be kept in the open position. When the material level in the crushing bin 2 is greater than the preset value, the control device controls the first drive member 5 to operate and rotate the baffle 4 to the closed position. When the material level in the crushing bin 2 is less than the preset value again, the control device controls the first drive member 5 to operate and drive the baffle 4 to the open position.

[0049] The material level detection element 6 can be, but is not limited to, an ultrasonic distance sensor. A first reference plane is provided above the crushing bin 2, and the ultrasonic distance sensor is provided on the first reference plane. The ultrasonic distance sensor can detect the distance between the first reference plane and the material surface in the crushing bin 2. The larger the distance, the smaller the material level in the crushing bin 2; the smaller the distance, the larger the material level in the crushing bin 2.

[0050] In this embodiment, at least two material level detection elements 6 are provided, and each material level detection element 6 is distributed along the circumference of the crushing bin 2. Multiple material level detection elements 6 can be used to detect the distance between multiple positions on the first reference plane of the crushing bin 2 and the material surface in the crushing bin 2, thereby obtaining the material level heights at multiple positions.

[0051] In some cases, the detected multiple material level heights have a certain consistency, indicating that the material surface in the crushing bin 2 is relatively flat. In the circumferential direction of the internal space of the crushing bin 2, the material distribution at each position is relatively even, and the crushing speed at each position is approximately the same.

[0052] In other cases, the consistency of the detected multiple material level heights is poor, indicating that the material surface in the crushing bin 2 has obvious ups and downs. The crushing speed at some positions in the crushing bin 2 is slow, and the crushing speed at some positions is fast, and there is a large difference between the crushing speeds at various positions.

[0053] In the specific implementation process, the material level heights at various positions in the crushing bin 2 can be comprehensively considered to control the rotation position of the baffle 4 to avoid the influence of accidental factors.

[0054] In this embodiment, the crusher further comprises a baffle position detection element 7 , and the baffle position detection element 7 is used to detect current position information of the baffle 4 .

[0055] The baffle position detection element is electrically connected to the control device, and the control device can obtain the current position information of the baffle 4 to confirm whether the baffle 4 is rotated into place.

[0056] In addition, in some embodiments, the baffle 4 can be controlled to have different rotation angles according to the material level in the crushing bin 2, so that the feed port 3 has different openings.

[0057] The baffle position detection element may be an encoder. The baffle 4 is provided with a rotating shaft portion, which is rotatably connected to the crusher body. The encoder is fixedly connected to the rotating shaft portion. The encoder can detect the angular displacement of the rotating shaft portion. The control device can determine the rotation angle of the baffle 4 based on the above angular displacement.

[0058] In this embodiment, the baffle 4 is arranged in a horizontal direction relative to the rotation axis of the crusher body 1. Specifically, the upper end of the baffle 4 can be rotatably connected to the crusher body 1.

[0059] When the baffle 4 is in the open position, the distance between the first end of the baffle 4 and the crushing bin 2 is greater than the distance between the second end of the baffle 4 and the crushing bin 2. That is, when the baffle 4 rotates from the closed position to the open position, the baffle 4 rotates toward the inside of the crushing bin 2, which can avoid the baffle 4 from affecting the materials on the feeding device 8. And when the baffle 4 rotates to the closed position, the materials on the feeding device 8 will not interfere with the baffle 4, which can ensure that the baffle 4 rotates smoothly to the closed position.

[0060] In summary, the crusher provided by the embodiment of the utility model has a simple structure, and the baffle 4 is used to participate in the adjustment, which can avoid the problem of not being able to feed materials in time and quickly when the material level in the crushing bin 2 of the crusher is low. The problem of frequent start and stop can be minimized, the production rhythm is ensured, the use quality of the crusher is improved, and the production efficiency is improved.

[0061] On the other hand, the embodiment of the present utility model further provides a crushing system, comprising a feeding device 8 and a crusher provided in any of the above embodiments, wherein the feeding device 8 is used to convey materials to the crusher. When the feeding to the crusher is stopped and then resumed, the crushing system in the present embodiment ensures timely and rapid feeding to the crusher, and the production efficiency is high. The derivation process of the beneficial effects of the crushing system in the embodiment of the present utility model is generally similar to the derivation process of the beneficial effects of the above crusher, and therefore will not be repeated here.

[0062] The crusher in this embodiment may be, but is not limited to, a jaw crusher; the feeding device 8 in this embodiment may be, but is not limited to, a belt conveyor, a vibrating feeder, and the like.

[0063] In this embodiment, the crushing system further includes a feeding state detection device 9, which is used to detect the state of the material on the feeding device 8. The state of the material on the feeding device 8 includes the height of the material on the feeding device 8.

[0064] The feeding state detection device 9 is electrically connected to the control device, and the control device can control the feeding speed of the feeding device 8 according to the height of the material on the feeding device 8. When the material level in the crushing bin 2 is appropriate, when the height of the material on the feeding device 8 is large, the feeding speed of the feeding device 8 is reduced; when the height of the material on the feeding device 8 is small, the feeding speed of the feeding device 8 is increased.

[0065] In some embodiments, the feeding state detection device 9 includes a distance sensor, which is arranged above the feeding device 8. There is a second reference plane above the feeding device 8, and the distance sensor is used to detect the distance value between the material surface on the feeding device 8 and the second reference plane. The larger the distance value, the smaller the height of the material on the feeding device 8; the smaller the distance value, the larger the height of the material on the feeding device 8.

[0066] The distance sensor mentioned above can be, but is not limited to, an ultrasonic distance sensor.

[0067] In other embodiments, the feeding state detection device 9 includes a proximity switch, which is arranged above the feeding device 8. At least two proximity switches are arranged, and the distances between each proximity switch and the feeding device 8 are different. The height of the material on the feeding device 8 is different, and the triggering conditions of each proximity switch are different.

[0068] Specifically, there are three proximity switches, namely the first proximity switch, the second proximity switch and the third proximity switch. The distance between the first proximity switch and the feeding device 8 is smaller than the distance between the second proximity switch and the feeding device 8, and the distance between the second proximity switch and the feeding device 8 is smaller than the distance between the third proximity switch and the feeding device 8. That is to say, the heights of the first proximity switch, the second proximity switch and the third proximity switch increase sequentially.

[0069] When only the first proximity switch is triggered, it means that the height of the material on the feeding device 8 is small; when the second proximity switch is triggered and the third proximity switch is not triggered, it means that the height of the material on the feeding device 8 is moderate; when the third proximity switch is triggered, it means that the height of the material on the feeding device 8 is large.

[0070] The above-mentioned proximity switches are all arranged above the feeding end of the feeding device 8. The proximity switches can be gathered together; or the proximity switches can be distributed at intervals, and the distribution direction of the proximity switches is perpendicular to the feeding direction of the feeding device 8.

[0071] In the embodiment of the present invention, the feeding device 8 includes a frame, a material trough, a second driving member and a third driving member.

[0072] The trough is arranged on the frame, the frame is used to support the trough, and the trough is used to convey materials. The first end of the trough is connected to the feed port 3 of the crusher, and the second driving member is arranged on the trough. When the second driving member is in operation, the trough can be driven to vibrate, so that the materials in the trough are conveyed to the crusher.

[0073] The second driving member can be, but is not limited to, a vibration motor.

[0074] The first end of the trough is rotatably connected to the frame, and the trough is arranged in a horizontal direction relative to the rotation axis of the frame. The third driving member is arranged between the trough and the frame, and the third driving member is used to drive the second end of the trough to rise and fall.

[0075] The third driving member can drive the trough to rotate around its first end by driving the second end of the trough to rise and fall, thereby adjusting the inclination of the trough and thus adjusting the feeding speed of the feeding device 8.

[0076] When the feeding speed of the feeding device 8 needs to be increased, the third driving member can be used to drive the second end of the trough to rise; when the feeding speed of the feeding device 8 needs to be reduced, the third driving member can be used to drive the second end of the trough to fall.

[0077] In a specific embodiment, the third driving member includes a hydraulic cylinder, a cylinder barrel of the hydraulic cylinder is hinged to the frame, and a piston rod of the hydraulic cylinder is hinged to the second end of the trough. By controlling the telescopic action of the hydraulic cylinder, the lifting and lowering of the second end of the trough can be achieved.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
