Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crushing equipment, in particular to a discharge structure of a hammer crusher. Background Art
[0002] The discharge port of a hammer crusher is generally arranged at the lower part. After the material is crushed, the crushed material will directly fall onto the belt below from the discharge port at the bottom of the crushing main machine. Since the belt is not protected, the crushed material is likely to scratch the belt, and the belt needs to be replaced after being used for a period of time.
[0003] In the existing hammer crusher technology, generally no solution is provided for this problem, but the discharge mechanisms of other crushers in this industry can be referred to, such as jaw crushers. The patent document with the application number 202322045035.4 discloses a discharge port guiding mechanism and a crusher. By moving the adjusting part, the guiding device can be driven to rotate, so that the guiding device is adjusted to a suitable angular position, and the adjusting part is limited and fixed by the first limiting part. Thus, the movement track of sharp materials can be effectively changed through the guiding device, playing a protective role for the belt.
[0004] Although this device can play a certain protective role for the belt, there are some problems in its use, which are mainly manifested in that the adjusting part is elastically connected to the guiding device. When the falling material continues, the adjusting part is always in a pressed state. At this time, the buffering effect is limited when the material impacts the guiding device, and all the crushed materials pass through and fall from the guiding device, resulting in large wear of the guiding device and high later maintenance cost. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a discharge structure of a hammer crusher with low maintenance cost and capable of effectively alleviating impact.
[0006] The technical solution adopted by the utility model to solve its technical problem is: the discharge structure of the hammer crusher includes a flexible guiding mechanism arranged at the discharge port of the hammer crusher. The flexible guiding mechanism includes a connecting plate on one side of the discharge port, mounting plates arranged at both ends of the connecting plate, an adjustable connecting seat connected between the two mounting plates, and a plurality of flexible chains with one end connected to the connecting plate and the other end connected to the adjustable connecting seat. The adjustable connecting seat slides along the mounting plate so that the flexible chains have different inclination angles.
[0007] Further, the flexible chains are iron chains.
[0008] Further, the flexible chains are steel cables, and a plurality of convex blocks are arranged at intervals on each steel cable.
[0009] Further, the adjustable connecting seat includes a connecting rod, a collar rotatably arranged on the connecting rod, and a connecting column with one end connected to the collar and the other end connected to the flexible chain;
[0010] A chute is provided on the mounting plate, and both ends of the connecting rod are slidably arranged in the chute and connected with a buffer mechanism.
[0011] Further, limiting protrusions are arranged at intervals on the connecting rod, and the collar is located between the limiting protrusions.
[0012] Further, fixing holes are provided at both ends of the connecting rod;
[0013] The buffer mechanism includes a connecting ear arranged on the mounting plate, a telescopic pin shaft penetrating through the connecting ear, a spring sleeved on the telescopic pin shaft, and an adjusting nut screwed on the telescopic pin shaft. One end of the spring presses against the connecting ear, and the other end presses against the adjusting nut.
[0014] Further, an installation ring is fixedly connected to the lower part of the connecting plate, a connecting ring is arranged at one end of the flexible chain, and the connecting ring is fixedly connected to the installation ring.
[0015] For the discharging structure of the hammer crusher, a connecting plate and a mounting plate are arranged at the discharging port and connected with a flexible chain. When the materials crushed by the hammer crusher fall to the discharging port, they will collide with the flexible chain. Since the middle section of the flexible chain is suspended, it will have a certain deformation margin. This deformation margin and the impact will slow down the falling speed of the crushed materials, so that the speed of the crushed materials falling onto the conveyor belt is greatly reduced, thereby protecting the conveyor belt from being scratched or cut. In addition, for the discharging structure of the hammer crusher of the present invention, a flexible chain is adopted, and there is a gap between each flexible chain, so that the materials fall from the gaps of the flexible chain, avoiding excessive wear caused by continuous friction of the crushed materials. Moreover, each flexible chain is independent, and when maintaining, a single flexible chain can be replaced according to the specific situation, effectively saving the maintenance cost.

[0025] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific embodiments of the present utility model will now be described in detail with reference to the accompanying drawings.
[0026] As Figures 1-6 shown, the discharging structure of the hammer crusher includes a flexible guiding mechanism provided at the discharge port 1 of the hammer crusher. The flexible guiding mechanism includes a connecting plate 2 on one side of the discharge port 1, mounting plates 3 provided at both ends of the connecting plate 2, an adjustable connecting seat 4 connected between the two mounting plates 3, and a plurality of flexible chains 5 with one end connected to the connecting plate 2 and the other end connected to the adjustable connecting seat 4. The adjustable connecting seat 4 slides along the mounting plate 3 so that the flexible chains 5 have different inclination angles.
[0027] In this discharging structure of the hammer crusher, the connecting plate 2 and the mounting plate 3 are provided at the discharge port 1 and the flexible chains 5 are connected. When the materials crushed by the hammer crusher fall to the discharge port 1, they will collide with the flexible chains 5. Since the middle section of the flexible chains 5 is suspended, it will have a certain deformation margin. This deformation margin and the impact will slow down the falling speed of the crushed materials, so that the speed of the crushed materials falling onto the conveyor belt is greatly reduced, thereby protecting the conveyor belt from being scratched or cut. In addition, in this discharging structure of the hammer crusher, the flexible chains 5 are used. There are gaps between each flexible chain 5, so that the materials fall through the gaps of the flexible chains 5, avoiding excessive wear caused by continuous friction of the crushed materials. Moreover, each flexible chain 5 is independent, and a single flexible chain 5 can be replaced according to the specific situation during maintenance, effectively saving the maintenance cost.
[0028] In this embodiment, the flexible chain 5 is an iron chain. To improve the wear resistance of the iron chain, the iron chain is made of wear-resistant steel. Of course, in some other embodiments, the flexible chain 5 can also be a steel cable, and a number of bumps 51 are arranged at intervals on each steel cable. In this embodiment, a mounting ring is fixedly connected to the lower part of the connecting plate 2, and a connecting ring is arranged at one end of the flexible chain 5, and the connecting ring is fixedly connected to the mounting ring.
[0029] The adjustable connecting seat 4 includes a connecting rod 41, a collar 42 rotatably arranged on the connecting rod 41, and a connecting column 43 with one end connected to the collar 42 and the other end connected to the flexible chain 5; a chute 44 is arranged on the mounting plate 3, and both ends of the connecting rod 41 are slidably arranged in the chute 44 and connected with a buffer mechanism 6. Among them, limiting protrusions 45 are arranged at intervals on the connecting rod 41, the collar 42 is located between the limiting protrusions 45, a threaded hole is opened on the connecting column 43, and the flexible chain 5 is fixedly connected by passing a screw through the threaded hole.
[0030] As shown in the figure, fixing holes 46 are arranged at both ends of the connecting rod 41. The buffer mechanism 6 includes a connecting ear 61 arranged on the mounting plate 3, a telescopic pin shaft 62 penetrating through the connecting ear 61, a spring 63 sleeved on the telescopic pin shaft 62, and an adjusting nut 65 screwed on the telescopic pin shaft 62. One end of the spring 63 presses against the connecting ear 61 and the other end presses against the adjusting nut 65. By turning the adjusting nut 65, the adjustment of the telescopic pin shaft 62 is realized, so as to adjust the position of the flexible chain 5 and the angle between the flexible chain 5 and the discharge port 1, and further the angle and position of the crushed material falling onto the conveyor belt can be adjusted.
[0031] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
[0032] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here.
