For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.
[0032] Figure 1 It is a schematic structural diagram of the feed crushing equipment according to an embodiment of the present disclosure. Figure 2 Schematic diagram of a cross-sectional view of a feed crushing device according to an embodiment of the present disclosure. Figure 1 and Figure 2 The feed crushing equipment of the embodiment of the present disclosure includes a crushing box 10, a crushing device 20 and a feeding device 30.
[0033] A pulverizing chamber 101 is formed in the pulverizing box 10 . The pulverizing device 20 is disposed in the pulverizing chamber 101 . Figure 3 Schematic diagram of the structure of the crushing device 20 according to the embodiment of the present disclosure. Figure 2 and Figure 3 The pulverizing device 20 includes a pulverizing blade 21 and a pulverizing driving member 22. The pulverizing blade 21 is rotatably arranged in the pulverizing chamber 101 around a vertical axis, and the pulverizing driving member 22 is connected to the pulverizing blade 21 to drive the pulverizing blade 21 to rotate, so as to pulverize the feed and make the pulverized feed fly.
[0034] Optionally, the pulverizing drive member 22 includes a motor. The motor is connected to the pulverizing blade 21 and is used to drive the pulverizing blade 21 to rotate around a vertical axis, so that the pulverizing blade 21 can pulverize the feed in the pulverizing chamber 101 .
[0035] Optionally, the crushing blade 21 includes a crushing shaft 211 and a plurality of crushing blades 212. The plurality of crushing blades 212 are arranged on the crushing shaft 211 at intervals in the up-down direction, and each layer includes a plurality of crushing blades 212. One end of the plurality of crushing blades 212 is connected to the crushing shaft 211, and the other ends are away from each other. Thus, when the crushing blade 21 rotates and crushes the feed, the plurality of crushing blades 212 can fully cut the feed, so that the particle size of the feed is cut small enough, thereby improving the crushing effect of the feed.
[0036] Specifically, the crushing blades 212 are three layers, and each layer includes four crushing blades 212. The four crushing blades 212 are arranged at intervals along the circumference of the crushing shaft 211, and one end of each crushing blade 212 is connected to the crushing shaft 211, and the other end is far away from each other. However, it can be understood that the number of layers of the crushing blades 212 and the number of the crushing blades 212 in each layer include but are not limited to this, and this is only for reference in conjunction with the present disclosure. Figure 3 A simple example is made.
[0037] Therefore, when feed such as straw stalks enters the crushing chamber 101, the crushing drive 22 can drive the crushing knife 21 to rotate fully, so that the crushing knife 21 can fully cut and crush the feed. At the same time, due to the rotation of the crushing knife 21, the feed will be thrown away under the action of centrifugal force after cutting and crushing.
[0038] The feeding device 30 forms an inlet channel 301 connected to the crushing chamber 101, a feed port 302 connected to the inlet channel 301, and a discharge port 303 extending downward to the top of the crushing knife 21, wherein the discharge channel 3012 of the feeding device 30 connected to the discharge port 303 extends in an inclined direction relative to the vertical direction and extends to the feed port 302 through at least one turning portion 31 to form a stop for splashing crushed feed to the feed port 302.
[0039] Optionally, the feed channel 301 includes a feed channel 3011 and a discharge channel 3012 connected to the feed channel 3011. The feed channel 3011 is connected to the feed port 302 and the discharge channel 3012 respectively, and a turning portion 31 is formed between the feed channel 3011 and the discharge channel 3012.
[0040] As a specific example, the feed channel 3011 extends in the vertical direction so that the turning portion 31 is formed between the feed channel 3011 and the discharge channel 3012 extending obliquely relative to the vertical direction.
[0041] Therefore, during crushing, the feed can smoothly enter the crushing chamber 101 through the feed feeding channel 301, and during the feed crushing process, after the thrown-away crushed feed enters the feed feeding channel 301, the obliquely extended discharge channel 3012 can stop the thrown-away crushed feed, especially when passing through the turning portion 31, the thrown-away feed will not turn spontaneously. Therefore, the above-mentioned arrangement of the present invention can prevent the flying crushed feed from continuing to move upward, thereby making it difficult for the crushed feed to reach the feed port 302 at the top, and further making it difficult for the thrown-away crushed feed to splash out from the feed port 302, and making it difficult for the thrown-away crushed feed to splash into the external environment.
[0042] It is understandable that there may be multiple turning parts 31. For example, before reaching the discharge channel 3012, the feed channel 3011 may turn once or multiple times to form two or more turning parts 31 and then extend to the discharge channel 3012.
[0043] According to some embodiments of the present disclosure, refer to Figure 2 The feed crushing device further comprises a screening component 40. The screening component 40 is used to screen the size of the crushed feed.
[0044] Figure 4 FIG. 4 is a partial structural diagram of the screening assembly 40 according to an embodiment of the present disclosure. Figure 4 The screening assembly 40 includes a first screen 41 and a flip driving member 42. The first screen 41 is disposed in the pulverizing chamber 101 and is located below the pulverizing device 20 so as to be flippable up and down, so as to screen the crushed feed when in a horizontal state, and to dump the crushed feed when flipped downward from a horizontal state to an inclined state. The flip driving member 42 is connected to the first screen 41 to drive the first screen 41 to flip.
[0045] Therefore, when the first screen 41 is in a horizontal state, the first screen 41 can screen the crushed feed, so that the feed above the predetermined particle size is retained above the first screen 41 to be fully crushed by the crushing device 20, and the feed below the predetermined particle size falls downward through the sieve holes of the first screen 41.
[0046] When too much feed is retained on the first screen 41 and the feed particle size is large, so that the sieve holes of the first screen 41 are blocked and the overall operation of the feed crushing device may fail, the flip drive 42 drives the first screen 41 to flip, so that the first screen 41 flips downward from the horizontal state, thereby, the feed intercepted on the first screen 41 is dumped, and then the first screen 41 is flipped back to the horizontal state, thereby, the first screen 41 can continue to work, thereby making the operation reliability of the entire crushing device 20 high and less prone to failure.
[0047] It can be understood that the pulverizing box 10 can be provided with a blockage detection member for detecting the blockage state of the first screen 41 to determine whether the first screen 41 needs to be turned over.
[0048] Optionally, the blockage detection member may be a pressure sensor, and the pressure sensor detects the air pressure in the pulverizing chamber 101 to determine whether the first screen 41 is blocked.
[0049] The blockage detection member may also be a weight sensor, and the weight sensor determines whether the first screen 41 is blocked by detecting the weight of the first screen 41 .
[0050] Optionally, the screening assembly 40 further includes an impact member 43 . The impact member 43 is disposed below the first screen 41 and can impact and cooperate with the flipped first screen 41 to make the crushed feed fall onto the first screen 41 .
[0051] Therefore, when the first screen 41 flips downward from the horizontal state, the first screen 41 will abut against the impact member 43 located below it, so that the first screen 41 is impacted and vibrates, thereby the crushed feed on the upper surface of the first screen 41 and the feed blocked in the sieve holes of the first screen 41 are shaken off onto the first screen 41, thereby fully releasing the blocking state of the first screen 41.
[0052] Optionally, one end of the impact member 43 is fixed below the first screen 41, and the other end is a free end, and the impact member 43 extends laterally. When the first screen 41 flips downward from a horizontal state, the free end of the impact member 43 can hit the first screen 41, so that the crushed feed on the first screen 41 can fully fall off the first screen 41.
[0053] According to some embodiments of the present disclosure, see Figure 2 The crushing box 10 forms a return port 103 located above the crushing knife 21 and connected to the crushing chamber 101. The feed crushing device also includes a return component 50. The return component 50 is used to return the crushed feed to the return port 103.
[0054] The material return assembly 50 includes a material return driving member 52. The material return driving member 52 is communicated with the grinding chamber 101 and the material return port 103 respectively to drive the ground feed to return to the grinding chamber 101.
[0055] Thus, the return drive 52 drives the ground feed to the return port 103 and enters the grinding chamber 101, so that the ground feed is ground again by the grinding device 20. Therefore, the present disclosure can ensure that the feed is fully ground.
[0056] Specifically, the feed return driving member 52 includes a suction pump, which is disposed between the feed return port 103 and the grinding chamber 101 to suck the ground feed toward the feed return port 103 .
[0057] Optionally, the return material assembly 50 further includes a return material conveying member 51 and a material extruding member 53. The return material conveying member 51 forms a return material channel 5101 located between the crushing chamber 101 and the return material driving member 52. Specifically, the return material channel 5101 extends obliquely relative to the horizontal direction. A drop opening 5401 connected to the return material channel 5101 is formed at the bottom of the return material conveying member 51. The material extruding member 53 is arranged in the return material channel 5101 to extrude and convey the crushed feed to the return material driving member 52.
[0058] Therefore, when the crushed feed with different particle sizes enters the return channel 5101 through the crushing chamber 101, the crushed feed with smaller particles can be directly discharged to the outside of the return channel 5101 through the drop port 5401, while the crushed feed with larger particles cannot pass through the drop port 5401 and will be retained in the return channel 5101. At this time, the return drive member 52 will drive the crushed feed with larger particles to the return port 103 and enter the crushing chamber 101, so that the crushed feed with larger particles is crushed again by the crushing device 20, and during the extrusion and transportation process, the extruding member 53 can also further extrude and crush the crushed feed, which is beneficial to improving the crushing effect of the crushing device 20.
[0059] Optionally, the extruding member 53 includes an extruding screw 531 and an extruding driving member 532. The extruding screw 531 is rotatably disposed in the return channel. The extruding driving member 532 is connected to the extruding screw 531 and is used to drive the extruding screw 531 to rotate, so that the extruding screw 531 extrudes and conveys the crushed feed to the return driving member 52.
[0060] Specifically, the extrusion screw 531 includes an extrusion shaft 5311 and an extrusion blade 5312. The extrusion shaft 5311 is rotatably disposed in the return channel 5101, and the extrusion blade 5312 is disposed on the outer peripheral wall of the extrusion shaft 5311 and extends in an axial spiral along the extrusion shaft 5311. Thus, when the extrusion screw 531 rotates, the crushed feed can be extruded and moved from one axial end of the extrusion shaft 5311 to the other axial end of the extrusion shaft 5311 under the action of the extrusion blade 5312, so as to be driven by the return drive member 52 disposed at the other axial end of the extrusion shaft 5311.
[0061] The extrusion drive member 532 includes an extrusion motor which is connected to the extrusion shaft 5311 and is used to drive the extrusion shaft 5311 to rotate, so that the extrusion shaft 5311 drives the extrusion blades 5312 to rotate to transport the feed.
[0062] According to some embodiments of the present disclosure, the feed crushing device further includes a second screen 54. The second screen 54 is arranged at the bottom of the return channel 5101 and forms the drop opening 5401.
[0063] Therefore, when the extrusion screw 531 squeezes the feed with a larger particle size and transports it to the return drive 52 , the feed with a smaller particle size will leak downward through the multiple drop openings 5401 on the second screen 54 .
[0064] It should be understood by those skilled in the art that the embodiments of the present disclosure described above and shown in the accompanying drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized. The functions and structural principles of the present disclosure have been demonstrated and explained in the embodiments, and the embodiments of the present disclosure may be deformed or modified in any way without departing from the principles.
