[0066] In view of the prior art, most coarse crushers are single-side fed, and when large and small materials are crushed at the same time, there is a problem of incomplete crushing, and the crushed materials are easy to accumulate and difficult to discharge, which is prone to leakage and collapse. The coarse crusher has a non-compact structure. This embodiment provides a coarse crusher to solve the above technical problems.

[0067] Specifically, Figure 1-3 As shown, the coarse crusher provided in this embodiment includes a crushing bin 3, a main crushing feed mechanism, a main crushing disc unit 4, a side crushing feed mechanism, a side crushing disc unit 5 and a conveying mechanism 8. The crushing bin 3 includes a main crushing bin 31 and a side crushing bin 32 connected to the main crushing bin 31. The main crushing bin 31 is provided with a side feed port (not shown in the figure) connected to the side crushing bin 32. The main crushing feed mechanism is used to convey the material to be crushed into the main crushing bin 31. The main crushing disc unit 4 is arranged in the main crushing bin 31, and is used to crush the material to be crushed conveyed by the main crushing feed mechanism; the side crushing feed mechanism is connected to the side crushing bin 32, and is used to convey the material to be crushed into the side crushing bin 32; the side crushing disc unit 5 is arranged in the side crushing bin 32, and is used to crush the material to be crushed in the side crushing bin 32, and convey the crushed material to the main crushing bin 31 through the side feed port; the conveying mechanism 8 is used to receive the crushed material in the main crushing bin 31 and convey the material to a designated location.

[0068] The coarse crusher provided in this embodiment has two feeding mechanisms. The main crushing feeding mechanism cooperates with the main crushing disc unit 4 to crush large materials, and the side crushing feeding mechanism cooperates with the side crushing disc unit 4 to crush small materials, thereby realizing the separate crushing of large materials and small materials, avoiding the problem of incomplete crushing, and the separate crushing also improves the crushing efficiency; in addition, the side crushed materials and the main crushed materials will be discharged into the main crushing bin 31, and then discharged to the conveying mechanism 8 and transported to the designated location. The structure is compact, the various mechanisms are well connected, and it is not easy to leak or collapse materials, thereby improving the safety of the working environment.

[0069] In this embodiment, the main crushing and feeding mechanism includes a main crushing and feeding unit 1 , and the main crushing and feeding unit 1 is used to convey the material to be crushed to the main crushing bin 31 .

[0070] Specifically, Figure 4 and Figure 5 As shown, the main crushing and feeding unit 1 includes a main crushing and conveying assembly 11, a first material transport bucket 12 and a second material transport bucket 13. The main crushing and conveying assembly 11 is used to transfer the material to be crushed to the main crushing bin, the first material transport bucket 12 is covered above the main crushing and conveying assembly 11, and both ends of the first material transport bucket 12 are provided with a first main feed port 121, and one end is used to communicate with the main crushing bin 31. The second material transport bucket 13 is provided with a second main feed port 131 on both adjacent sides, and the second material transport bucket 13 is hinged to the other end of the first material transport bucket 12, and the second material transport bucket 13 can be switched from the first state to the second state. In the first state, the second main feed port 131 on one side of the second material transport bucket 13 is flush with the upper surface of the first material transport bucket 12, and the other second main feed port 131 is communicated with the first main feed port 121. The second state is that the second material transport bucket 13 is flipped upward to expose the first main feed port 121.

[0071] The main crushing and conveying component 11 in the main crushing and feeding unit 1 provided in this embodiment can adjust the feeding mode according to the amount of material to be crushed. When the second material transport bucket 13 is in the first state, the machine is used to automatically place the material to be crushed in this state, which is suitable for use when there is a lot of material to be crushed. The material to be crushed is placed on the main crushing and conveying component 11 through the second main feeding port 131 on the upper side of the second material transport bucket 13, thereby improving the feeding efficiency; when the second material transport bucket 13 is in the second state, the material to be crushed is placed manually in this state, which is suitable for use when there is a small amount of material to be crushed. The material to be crushed is placed on the main crushing and conveying component 11 through the first main feeding port 121, thereby saving energy for machine feeding.

[0072] In this embodiment, the first material transport bucket 12 includes a plurality of transport sub-buckets 122, and the plurality of transport sub-buckets 122 are detachably connected end to end in sequence. Preferably, they are connected by bolts, and the connection structure is simple and easy to operate. The number of transport sub-buckets 122 can be set according to the length of the main crushing and conveying assembly 11, and the first material transport bucket 12 is assembled using a plurality of transport sub-buckets 122, which is convenient for processing and transportation of equipment.

[0073] The transport bucket 122 includes two bucket vertical plates arranged opposite to each other, which are installed on both sides of the main crushing and conveying assembly 11 to play the role of blocking materials and prevent the materials to be crushed from falling from both sides of the main crushing and conveying assembly 11. Furthermore, the ends of the two bucket vertical plates away from the main crushing and conveying assembly 11 can also be connected by a bucket horizontal plate to form a top-closed structure to prevent dust generated during feeding from being blown out and reduce dust pollution generated during production.

[0074] In this embodiment, when the second material transport bucket 13 is in the first state, the second material transport bucket 13 is detachably connected to the first material transport bucket 12 through a first connecting piece to strengthen the strength of the connection between the second material transport bucket 13 and the first material transport bucket 12 when the second material transport bucket 13 is in the first state, thereby improving the supporting force when injecting the material to be crushed into the second material transport bucket 13.

[0075] Optionally, the first connecting member includes a connecting bolt, and the first material transport bucket 12 and the second material transport bucket 13 are provided with corresponding connecting threaded holes for connecting with the connecting bolts. The connecting structure is simple, easy to install and disassemble, and has high connection strength.

[0076] In order to improve the conveying efficiency of the material to be crushed, in this embodiment, when the second material transport bucket 13 is in the first state, the bottom wall of the second material transport bucket 13 is tilted upward from the end close to the first material transport bucket 12. The material to be crushed falling into the second material transport bucket 13 slides onto the main crushing conveying assembly 11 through the tilted bottom wall. Specifically, the second material transport bucket 13 includes two right-angled triangular side panels and a bottom panel, the bottom panel connects the hypotenuses of the two side panels, and further forms two adjacent second main feed ports 131, and the edges of the two side panels can be connected to the vertical panels of the first material transport bucket 12.

[0077] The second material transport bucket 13 can be switched from the first state to the second state, or from the second state to the first state. In this embodiment, the second material transport bucket 13 is hinged to the first material transport bucket 12 through a hinge. When the second material transport bucket 13 is switched from the first state to the second state, the second material transport bucket 13 flips upward 180°, and the second material transport bucket 13 overlaps the first material transport bucket 12, which improves the stability of the second material transport bucket 13 in the second state, and can fully expose the first main feed port 121 for manual loading. Furthermore, a second connecting member 15 is provided on the second material transport bucket 13, and the second connecting member 15 is detachably connected to the first material transport bucket 12, which further improves the stability of the second material transport bucket 13 in the second state.

[0078] In this embodiment, the second material transport bucket 13 and the first material transport bucket 12 are both made of metal, and the second connecting member 15 is preferably a magnetic member. When the second material transport bucket 13 is overlapped on the first material transport bucket 12, the magnetic member is adsorbed on the first material transport bucket 12. In other embodiments, the second connecting member 15 can also be a buckle structure, and the second material transport bucket 13 and the first material transport bucket 12 are fixed by the buckle structure.

[0079] When switching the state of the second material transport bucket 13, for easy operation, a transport bucket handle 14 is further provided on the second material transport bucket 13, and the transport bucket handle 14 is held to adjust the state of the second material transport bucket 13. Specifically, a transport bucket handle 14 is provided on two opposite side walls of the second material transport bucket 13.

[0080] In this embodiment, the main crushing and conveying assembly 11 includes a chain plate shaft, a chain plate and a driver. Two chain plate shafts are provided, and the two chain plate shafts are arranged in parallel and spaced apart. The chain plate transmission connects the two chain plate shafts. The driver is connected to one of the chain plate shafts, and the driver can drive one chain plate shaft to rotate and drive the chain plate transmission. The chain plate transmission mechanism is used instead of the traditional belt transmission mechanism. Compared with the belt, the chain plate is not easy to be damaged and has a long service life, thereby reducing the failure rate of the main crushing feeding mechanism.

[0081] like Figure 6-8 As shown, the main crushing and feeding mechanism provided in this embodiment further includes a main pressing wheel unit 2, which is arranged between the main crushing and feeding unit 1 and the main crushing bin 31, and is used for pressing the material to be crushed.

[0082] Specifically, the main pressing wheel unit 2 includes a pressing wheel frame 21, which is rotatably connected to the main crushing bin 31, and the pressing wheel frame 21 is provided with a main pressing wheel 22 and a main pressing wheel driving member for driving the main pressing wheel 22 to rotate, and an elastic member 23 is provided between the pressing wheel frame 21 and the main crushing bin 31, and the elastic member 23 causes the main pressing wheel 22 to press against the material to be crushed. The main pressing wheel 22 in the main pressing wheel unit 2 provided in this embodiment rotates to convey the material to be crushed into the main crushing bin 31, and the main pressing wheel 22 is elastically connected to the main crushing bin 31 through the pressing wheel frame 21 and the elastic member 23. In the process of pressing and conveying the material to be crushed, the material to be crushed can push the main pressing wheel 22 upward, and due to the elastic force of the elastic member 23 and the gravity of the main pressing wheel 22 itself, the material to be crushed is clamped and conveyed to the main crushing bin 31, and the main pressing wheel 22 can be adjusted up and down according to the size of the material to be crushed, and there will be no slipping or jamming of the material, thereby ensuring the continuity of conveying the material to be crushed and improving the material pressing and transporting effect of the main pressing wheel 22.

[0083] In this embodiment, the pressure wheel frame 21 includes two side swing arms 211, one end of the two side swing arms 211 is rotatably connected to the two side walls opposite to the main crushing bin 31, the two ends of the rotating shaft of the main pressure wheel 22 are rotatably connected to the other ends of the two side swing arms 211, and the middle part of the side swing arms 211 is connected to the elastic member 23. The main pressure wheel driving member drives the main pressure wheel 22 to rotate relative to the side swing arms 211. The main pressure wheel driving member is installed on one of the side swing arms 211 and can be raised and lowered simultaneously with the main pressure wheel 22. Since the main pressure wheel 22 is relatively heavy, the structure of the pressure wheel frame 21 is easy to install the main pressure wheel 22.

[0084] In order to facilitate feeding and pressing of materials, in the present embodiment, the main pressing wheel 22 is provided with a plurality of rows of pressing wheel teeth 221 along the circumferential direction, and each row of pressing wheel teeth 221 extends in a concave shape along the axial direction of the main pressing wheel 22, and the two ends of the pressing wheel teeth 221 are inclined, so that the material to be crushed will not leak out from the two ends of the main pressing wheel 22, thereby further improving the effect of pressing and transporting the materials.

[0085] The elastic member 23 is preferably a spring. When the main pressure wheel 22 is lifted, the spring is stretched, and the main pressure wheel 22 presses the material to be crushed by relying on the gravity of the main pressure wheel 22 and the tension of the spring, so that the material to be crushed is continuously transported to the main crushing bin 31.

[0086] A material shielding plate 24 is provided above the main pressing wheel 22 in the feeding direction, and the material shielding plate 24 is connected to the pressing wheel frame 21 and protrudes from the pressing wheel frame 21. The material shielding plate 24 can effectively shield the material to be crushed from splashing when the material to be crushed enters the main pressing wheel 22, thereby ensuring the safety of the operator.

[0087] The main crushing blade unit 4 is arranged in the main crushing chamber 31. Figure 9-10As shown, the main pulverizing blade disc unit 4 includes a connecting plate 42, a main blade shaft 43 and a blade mounting shaft 44. Two connecting plates 42 are provided, and the two connecting plates 42 are arranged at intervals, serving as the supporting part of the main pulverizing blade disc unit 4. One end of the main blade shaft 43 is sequentially penetrated by two connecting plates 42, and the main blade shaft 43 is fixedly connected to the connecting plate 42. One end of the main blade shaft 43 is connected to the blade disc driver, and the blade disc driver can drive the main blade shaft 43 to rotate, thereby driving the entire main pulverizing blade disc unit 4 to rotate. A plurality of blade mounting shafts 44 are provided in the circumference of the main blade shaft 43, and both ends of the blade mounting shaft 44 are fixedly connected to the connecting plate 42. A plurality of the above-mentioned pulverizing blades 41 are arranged at intervals on each blade mounting shaft 44, and the pulverizing blade 41 can rotate around the blade mounting shaft 44.

[0088] When the blade driver drives the main blade shaft 43 to rotate, the blade mounting shaft 44 also rotates accordingly. The crushing blade 41 can swing around the blade mounting shaft 44 within a certain range under the action of centrifugal force to cut the material to be crushed, thereby avoiding hard contact between the crushing blade 41 and the material to be crushed, extending the service life of the crushing blade 41, reducing the cost of use, and having low noise and vibration during crushing and cutting.

[0089] In this embodiment, the crushing blades 41 on the plurality of blade mounting shafts 44 are staggered to avoid mutual interference between the crushing blades 41 when swinging, and the crushing blades 41 can be arranged more densely, thereby increasing the cutting density and effectively crushing the material. The arrangement of the crushing blades 41 between the blade mounting shafts 44 is arranged according to the actual installation and is not specifically limited here.

[0090] In this embodiment, four blade mounting shafts 44 are provided, and two blade mounting shafts 44 are provided at intervals on opposite sides of the main blade shaft 43, which can ensure effective cutting of the main crushing blade disc unit 4. However, the number of blade mounting shafts 44 can be set according to the size of the main crushing blade disc, and is not specifically limited here.

[0091] In order to facilitate installation and removal of the crushing blades 41, in this embodiment, a spacer 45 is provided between two adjacent crushing blades 41, and the spacer 45 is movably sleeved on the blade installation shaft 44. The spacer 45 can limit the distance between two adjacent crushing blades 41.

[0092] Furthermore, the spacers 45 are of various types, and the lengths of the spacers 45 are different. The lengths of the spacers 45 on each blade mounting shaft 44 can be different, and the lengths of the spacers 45 between multiple blade mounting shafts 44 can also be different, so that the crushing blades 41 can be arranged in various ways to form main crushing blade discs of different specifications, thereby improving the flexibility of the main crushing blade disc unit 4 assembly to be suitable for different application scenarios.

[0093] In this embodiment, the main pulverizing blade disc unit 4 also includes a plurality of separator discs 46, which are placed between the two connecting plates 42 and are spaced apart and sleeved on the main blade shaft 43 and the blade mounting shaft 44. When the main pulverizing blade disc unit 4 cuts the material to be pulverized, the separator discs 46 can press the material to be pulverized to improve the cutting effect of the main pulverizing blade disc. The separator discs 46 can also divert the material entering the main pulverizing blade disc unit 4 to improve the cutting efficiency and cutting effect. In addition, the separator discs 46 can also play a supporting role to prevent the main blade shaft 43 and the blade mounting shaft 44 from bending. The number of separator discs 46 is not specifically limited here and is set according to actual needs.

[0094] like Fig.11 As shown, the crushing blade 41 provided in this embodiment includes a blade body 411, one end of the blade body 411 is provided with a mounting hole 412, and both sides of the other end are provided with an arc groove 413 concave inwardly, and the groove wall of the arc groove 413 forms a sharp angle 414 with the end face of the blade body 411. The crushing blade 41 is provided with two concave arc grooves 413, and the sharp angle 414 formed by the groove wall of the arc groove 413 and the end face of the blade body 411 is a blade. Both sides of the crushing blade 41 can cut the material to be crushed. When the blade on one side is damaged, the installation position of the crushing blade 41 can be replaced, and the blade on the other side can be used for cutting, so as to realize the secondary use of the crushing blade 41, and the cut material can be discharged through the cutting angle of the arc groove 413; in addition, the noise and vibration of the material to be crushed by the formed blade are small compared with the hammering method in the prior art, and the crushing blade 41 is not easy to be damaged, which reduces the use cost.
