Description

Technical Field

[0001] The invention belongs to the technical field of feed crushing, and in particular relates to a feed crushing device and a working method thereof. Background Art

[0002] Feed shredder is a coarse crushing machine, generally used to process unprocessed raw materials or scraps. The shredder usually drives the shredder shaft to squeeze and crush the material through the rotating shredder shaft. When working, it is generally used in conjunction with a rotating screen drum to achieve coarse crushing and screening of feed.

[0003] There are several baffles on the inner wall of the rotating screen drum. The rotating barrel will screen the shredded material fragments through the sieve holes on the rotating screen drum to screen out the oversized feed fragments. The rotating screen drum will then drive the oversized material fragments to rotate together through the baffles, so that the oversized material fragments move to the upper side of the shredder and fall back into the shredder for secondary crushing.

[0004] However, in the process of the baffle in the above-mentioned rotating screen drum driving the larger feed fragments to rotate and lift, an arc plate needs to be set up to block them, so as to prevent the feed fragments from falling back into the rotating screen drum before they are lifted above the feed inlet of the shredder, causing them to be unable to re-enter the shredder. For larger feed fragments, when the feed is stored for a long time, the water content at the bottom of the feed pile is relatively high. Therefore, the larger feed fragments remaining after the initial crushing by the crusher are mostly feed with a high water content. Because of the provision of the arc plate, when the baffle lifts the feed fragments, the feed fragments will contact the surface of the arc plate during the lifting process. As the baffle is lifted, some of the feed fragments will be pressed on the surface of the arc plate, making them difficult to remove. In addition, the water-containing feed will gradually accumulate on the baffle during the lifting process, which will block the sieve holes near the baffle on the rotating screen drum.

[0005] Therefore, it is necessary to design a feed crushing device and a working method thereof which can simultaneously clean the arc baffle and the blocked sieve holes in the process of the baffle driving the feed fragments to lift, so as to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a feed crushing device and a working method thereof.

[0007] In order to solve the above technical problems, the present invention provides a feed crushing device, which comprises:

[0008] A first conveyor belt, used for conveying straw;

[0009] a crusher, adapted to receive the feed on the first conveyor belt and crush the feed; and

[0010] The circulating filtering mechanism comprises: a filter ring rotatably arranged on the periphery of the crusher, at least one baffle plate located on the inner wall of the filter ring, and a guide plate located at the center of the filter ring; wherein

[0011] A filter hole group is provided on the side wall of the filter ring, a scraper capable of being moved under force is provided in the baffle, a magnetic part is provided on one side of the guide plate, and a hot air blower is provided above the filter ring;

[0012] The hot air blower is suitable for cleaning the filter hole group and drying the feed, the filter ring is suitable for filtering out the agglomerated feed, the baffle is suitable for blocking the agglomerated feed and driving it to move upward, and then guiding the unqualified feed into the crusher for secondary crushing through cooperation with the guide plate; and

[0013] In the early stage when the baffle plate is connected to the guide plate, the magnetic member is suitable for driving the scraper to extend out of the baffle plate until it abuts against the surface of the guide plate to clean the residual feed; and

[0014] In the later stage when the baffle plate is connected to the material guide plate, the magnetic member is suitable for driving the scraper blade to retreat and triggering the hot air blower to increase its output power.

[0015] In a second aspect, the present invention further provides a working method of the feed crushing device as described above, comprising:

[0016] Filter the crushed feed by rotating the filter ring;

[0017] The baffle drives the agglomerated feed to move upward, and cooperates with the guide plate to allow the agglomerated feed to enter the crusher for secondary crushing;

[0018] In the early stage when the baffle plate is connected with the guide plate, the scraper is driven by the magnetic part to extend out of the baffle plate until it contacts the surface of the guide plate to clean the residual feed;

[0019] In the later stage when the baffle plate is connected with the guide plate, the scraper is driven backward by the magnetic part and the hot air blower is triggered to increase its output power.

[0020] The beneficial effect of the present invention is that, in the process of crushing feed by the crusher in the feed crushing device, some damp feed will appear agglomeration, and these agglomerated feeds will affect subsequent use. Therefore, in the present scheme, a filter ring is provided, and the filter hole group on the filter ring can only pass qualified small-particle feed, and large-particle agglomerated feed will be blocked in the filter ring; in order to crush the agglomerated feed again, the present scheme provides a baffle and a guide plate, and the baffle will drive these agglomerated feeds to move upward in the process of moving from bottom to top. When the baffle is in a horizontal state, if the baffle continues to rotate, it will cause the agglomerated feed to fall, so at this time, the baffle and the guide plate are close to each other to form a accommodating space, and the baffle drives the agglomerated feed to move on the guide plate until it moves to the top of the crusher, and then falls into the crusher for secondary crushing; in order to reduce the possibility of feed agglomeration as much as possible, the present scheme provides a hot air blower, and the hot air generated by the hot air blower reduces the humidity of the feed agglomerates. At the same time, the hot air blower will clean the filter hole group on the filter ring during the blowing process to prevent the residual feed therein from affecting The scraper blade is arranged in the baffle plate, and when the baffle plate moves to the guide plate, the magnetic part on the guide plate attracts the scraper blade to move out of the baffle plate until it contacts the surface of the guide plate, thereby achieving cleaning by movement; in the process of filtering feed, the closer the filter hole group is to the baffle plate, the more agglomerated feed is filtered out (the agglomerated feed filtered out before will be accumulated), so that the filter holes closer to the baffle plate are more likely to be blocked. The easier it is to get clogged, therefore, this solution sets the hot air blower to be power-adjustable (such as: through the movement of the power adjustment sheet) to adapt to the filter hole group. Specifically, the front and rear sections of the magnetic part have opposite magnetic properties. The front section is used to suck the scraper blade, and the rear section is used to push the scraper blade, so that the rear end of the scraper blade drives the power adjustment sheet to move. In summary, this solution realizes the filtration and secondary crushing of agglomerated feed, and real-time cleaning of residual feed on the guide plate during work, as well as automatic adjustment of the power of the hot air blower to clean the corresponding filter holes in the filter hole group and dry the agglomerated feed.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0035] like Figure 1 , Figure 2 , Figure 3As shown, this embodiment provides a feed crushing device, which includes: a first conveyor belt 1 for conveying straw; a crusher 2, suitable for receiving the feed on the first conveyor belt 1 and crushing it; and a circulating filtering mechanism 3, which includes: a filter ring 31 rotatably arranged on the periphery of the crusher 2 and at least one baffle 32 located on the inner wall of the filter ring 31, and a guide plate 33 located at the center of the filter ring 31; wherein the side wall of the filter ring 31 is provided with a filter hole group 34, the baffle 32 is provided with a scraper 35 that can be moved under force, a magnetic part 36 is provided on one side of the guide plate 33, and a hot air blower 37 is provided above the filter ring 31. ; The hot air blower 37 is suitable for cleaning the filter hole group 34 and drying the feed, the filter ring 31 is suitable for filtering out the agglomerated feed, the baffle 32 is suitable for blocking the agglomerated feed and driving it to move upward, and then guiding the unqualified feed into the crusher 2 for secondary crushing through cooperation with the guide plate 33; and in the early stage when the baffle 32 is connected to the guide plate 33, the magnetic member 36 is suitable for driving the scraper 35 to extend out of the baffle 32 until it abuts against the surface of the guide plate 33 to clean the residual feed; and in the later stage when the baffle 32 is connected to the guide plate 33, the magnetic member 36 is suitable for driving the scraper 35 to retreat and trigger the hot air blower 37 to increase its output power.

[0036] In this embodiment, during the process of crushing the feed by the crusher 2, some damp feed will clump, and these clumped feeds will affect the subsequent use. Therefore, in this solution, a filter ring 31 is provided, and the filter hole group 34 on the filter ring 31 can only pass qualified small-particle feed, and large-particle clumped feed will be blocked in the filter ring 31; in order to crush the clumped feed again, the baffle 32 and the guide plate 33 are provided in this solution. When the baffle 32 moves from bottom to top, it will drive these clumped feeds to move upward. When the baffle 32 is in a horizontal state, if the baffle 32 continues to rotate, This will cause the agglomerated feed to fall, so at this time, the baffle plate 32 and the guide plate 33 are close to each other to form a accommodating space, and the baffle plate 32 drives the agglomerated feed to move on the guide plate 33 until it moves to the top of the crusher 2, and then falls into the crusher 2 for secondary crushing; in order to reduce the possibility of feed agglomeration as much as possible, the present scheme is provided with a hot air blower 37, and the hot air generated by the hot air blower 37 reduces the humidity of the feed agglomerates. At the same time, the hot air blower 37 will clean the filter hole group 34 on the filter ring 31 during the blowing process to prevent the residual feed therein from affecting subsequent use; the guide plate 33 During use, there will be feed residues on it. These feed residues are easy to adhere to the surface of the guide plate 33 when exposed to hot air and are difficult to clean. Therefore, in this solution, a scraper 35 is set in the baffle 32. When the baffle 32 moves to the guide plate 33, the magnetic member 36 on the guide plate 33 will attract the scraper 35 to move out of the baffle 32 until it contacts the surface of the guide plate 33, thereby achieving cleaning through movement; in the process of filtering feed, the closer the filter hole group 34 is to the baffle 32, the more agglomerated feed is filtered out (the agglomerated feed filtered out previously will be accumulated), so that the filter holes closer to the baffle 32 are easier to filter out. Therefore, in this solution, the hot air blower 37 is set to be power-adjustable (such as by moving the power adjustment sheet 372) to adapt to the filter hole group 34. Specifically, the front section and the rear section of the magnetic member 36 have opposite magnetism, the front section is used to suck the scraper sheet 35, and the rear section is used to push the scraper sheet 35, so that the rear end of the scraper sheet 35 drives the power adjustment sheet 372 to move; in summary, this solution realizes the filtration and secondary crushing of the agglomerated feed, and real-time cleaning of the residual feed on the guide plate 33 during the working process, and enables the hot air blower 37 to automatically adjust the power to clean the corresponding filter holes in the filter hole group 34, and dry the agglomerated feed.

[0037] like Figure 4 As shown, in this embodiment, the guide plate 33 is curved in an arc shape, and its initial end 331 is located in the middle of the filter ring 31, and a material drop notch 332 is opened at its tail; the material drop notch 332 is located above the crusher 2.

[0038] In this embodiment, after the baffle 32 rotates to a horizontal position, if the baffle 32 continues to rotate, it will tilt downward, causing the agglomerated feed thereon to fall off, and therefore it needs to cooperate with the guide plate 33. Specifically, the guide plate 33 is fixedly arranged, and its curvature is adapted to the moving trajectory of the end of the baffle 32, so that the end of the baffle 32 can move close to the guide plate 33, thereby driving the agglomerated feed to move along the guide plate 33 until it falls into the crusher 2.

[0039] In this embodiment, the magnetic member 36 is arranged to be in an arc shape that matches the guide plate 33; the outer wall of the scraper 35 is provided with a force-bearing portion 351; the magnetism of the front section of the magnetic member 36 is different from the magnetism of the front end of the force-bearing portion 351, so as to drive the scraper 35 to extend out of the baffle 32; and the magnetism of the rear section of the magnetic member 36 is the same as the magnetism of the front end of the force-bearing portion 351, so as to drive the scraper 35 to retreat, and at the same time, the tail of the force-bearing portion 351 triggers the adjustment switch of the hot air blower 37 during the follow-up rotation process.

[0040] In this embodiment, the rear section of the magnetic member 36 is located at the blanking notch 332 .

[0041] In this embodiment, the front and rear sections of the magnetic member 36 have opposite magnetic poles, so that when the force-bearing portion 351 moves to the front section, it drives the scraper 35 to extend out of the baffle 32, and when the force-bearing portion 351 moves to the rear section, it drives the scraper 35 to retreat.

[0042] like Figure 3 As shown, in this embodiment, the filter ring 31 and the hot air blower 37 are both arranged on the bracket 4; the hot air blower 37 is provided with an arc slide 371 adapted to the filter ring 31 on the bracket 4, and a power adjustment sheet 372 is provided on the arc slide 371; when the scraper 35 retreats, it drives the power adjustment sheet 372 to move along the arc slide 371 to gradually increase the power of the hot air blower 37, while the hot air blower 37 gradually cleans the filter hole group 34 close to the baffle 32.

[0043] In this embodiment, the second magnet is placed next to the blanking notch 332. When the baffle 32 moves to the blanking notch 332, all the agglomerated feed has been pushed into the blanking notch 332 and falls into the crusher 2. At this time, the scraper 35 no longer needs to clean the guide plate 33. The force-bearing part 351 moves backward to drive the power adjustment sheet 372 to move, thereby enhancing the output power of the hot air blower 37 to better clean the filter hole group 34 near the baffle 32; wherein, the scraper 35 and the power adjustment sheet 372 are reset by a reset spring.

[0044] In this embodiment, a second conveyor belt 5 for receiving qualified feed is provided below the filter ring 31 .

[0045] In this embodiment, the second conveyor belt 5 is used to receive the qualified feed filtered by the filter ring 31 and transport it away.

[0046] The present embodiment also provides a working method of the feed crushing device as described above, which includes: filtering and crushing the feed by rotating the filter ring 31; driving the agglomerated feed to move upward by the baffle 32, and cooperating with the guide plate 33 to allow the agglomerated feed to enter the crusher 2 for secondary crushing; in the early stage when the baffle 32 is connected with the guide plate 33, driving the scraper 35 to extend out of the baffle 32 by the magnetic part 36 until it abuts against the surface of the guide plate 33 to clean the residual feed; in the later stage when the baffle 32 is connected with the guide plate 33, driving the scraper 35 to retreat by the magnetic part 36 and triggering the hot air blower 37 to increase its output power.

[0047] For the specific structure and implementation process of the feed crushing device, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0048] In summary, during the process of crushing feed by the crusher 2 in the feed crushing device, some damp feed will clump, and these clumps of feed will affect subsequent use. Therefore, in the present solution, a filter ring 31 is provided, and the filter hole group 34 on the filter ring 31 can only pass qualified small particles of feed, and large particles of clumps of feed will be blocked in the filter ring 31; in order to crush the clumps of feed again, the present solution is provided with a baffle 32 and a guide plate 33. When the baffle 32 moves from bottom to top, it will drive these clumps of feed to move upward. When the baffle 32 is in a horizontal state, if the baffle 32 continues to If the feed is continuously rotated, it will cause the agglomerated feed to fall, so at this time, the baffle plate 32 and the guide plate 33 are close to each other to form a accommodating space, and the baffle plate 32 drives the agglomerated feed to move on the guide plate 33 until it moves to the top of the crusher 2, and then falls into the crusher 2 for secondary crushing; in order to reduce the possibility of feed agglomeration as much as possible, the present scheme is provided with a hot air blower 37, and the hot air generated by the hot air blower 37 reduces the humidity of the feed agglomerates. At the same time, the hot air blower 37 will clean the filter hole group 34 on the filter ring 31 during the blowing process to prevent the residual feed therein from affecting the subsequent use; the guide plate During the use of the baffle plate 33, there will be feed residues on it. These feed residues are easy to adhere to the surface of the guide plate 33 when exposed to hot air and are difficult to clean. Therefore, in this solution, a scraper 35 is arranged in the baffle plate 32. When the baffle plate 32 moves to the guide plate 33, the magnetic member 36 on the guide plate 33 attracts the scraper 35 to move out of the baffle plate 32 until it contacts the surface of the guide plate 33, thereby cleaning it by moving; in the process of filtering feed, the closer the filter hole group 34 is to the baffle plate 32, the more agglomerated feed is filtered out (the agglomerated feed filtered out previously will be accumulated), so that the filter holes closer to the baffle plate 32 are more likely to be filtered out. Therefore, in this solution, the hot air blower 37 is set to be power-adjustable (such as by moving the power adjustment sheet 372) to adapt to the filter hole group 34. Specifically, the front section and the rear section of the magnetic member 36 have opposite magnetism. The front section is used to suck the scraper 35, and the rear section is used to push the scraper 35, so that the rear end of the scraper 35 drives the power adjustment sheet 372 to move. In summary, this solution realizes the filtration and secondary crushing of the agglomerated feed, and cleans the residual feed on the guide plate 33 in real time during the working process, and enables the hot air blower 37 to automatically adjust the power to clean the corresponding filter holes in the filter hole group 34, and dry the agglomerated feed.
