Description

Technical Field

[0001] The invention relates to the technical field of cow dung turning and throwing, in particular to a crawler type cow dung turning and throwing machine. Background Art

[0002] The composting machine is a mechanical equipment developed and produced based on dynamic composting. It can make cow dung fully contact with air through turning and stirring actions, accelerate the decomposition of organic matter in the cow dung, and promote aerobic fermentation process.

[0003] Although the turning and throwing machine in the prior art can break up the cow dung by turning and throwing, in actual work, due to the influence of factors such as the operation mode, material moisture and density, only large pieces of cow dung will be broken up, while small pieces of cow dung will be thrown backwards, that is, small pieces of cow dung are difficult to be effectively broken up; Among the existing related technical solutions, four Chinese patents with patent announcement numbers CN216919059U, CN221217690U, CN217377740U and CN107056356B disclose four different turning machines, but the four turning machines still achieve the function of breaking up cow dung through turning and throwing actions. Cow dung can easily form lumps during the composting fermentation process. For example, the steam generated during the composting process can cause the cow dung to stick together, the sticky substances generated by microbial decomposition can cause the cow dung to stick together, and the cow dung at the bottom of the compost is compressed into lumps due to the greater pressure.

[0004] During the tossing process, the force acting on the lumps is likely to be uneven, causing the outer part to be broken up while the inner part still has lumps remaining. In addition, the lumps may collide or entangle with each other during the tossing process, further resulting in residual lumps. The residual cow dung lumps will not only reduce the uniformity of fermentation, but also reduce the efficiency of cow dung fermentation. In addition, in order to avoid collision between the turning parts and the ground, the turning parts of the turning machine are usually raised. However, when the turning parts are raised, it is difficult for them to contact the cow dung at the bottom layer, which makes it more difficult for the cow dung compressed into agglomerates at the bottom layer to be effectively turned, further reducing the uniformity and efficiency of cow dung fermentation. Therefore, it is necessary to design a crawler type cow dung turning machine which can effectively avoid residual lumps and can effectively turn over the bottom layer of cow dung in order to address the shortcomings of the prior art turning machines which only break up cow dung through turning over action, resulting in residual lumps and the bottom layer of cow dung being difficult to be effectively turned over.

DETAILED DESCRIPTION

[0026] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0027] Embodiment 1: A crawler type cow dung turning machine, such as Figure 1-Figure 3As shown, it includes a flipping machine box 1, a crawler walking mechanism 101, a flipping shaft 102, a flipping claw 103, a flat screen 104, a curved screen 105 and an upper crushing shaft 106. The flipping machine box 1 is equipped with a crawler walking mechanism 101, which is used to drive the flipping machine box 1 to move. The left and right side walls of the flipping machine box 1 are connected to the flipping shaft 102 for rotation. A plurality of flipping claws 103 are fixedly connected to the flipping shaft 102 in a ring array. A flat screen 104 and a curved screen 105 are arranged in the flipping machine box 1. The curved screen 105 The screen 105 is located at the rear side of the plane screen 104, and the plane screen 104 is tilted with the front higher and the back lower. The flipping claw 103 is used to throw the cow dung backwards onto the plane screen 104. The cow dung with qualified particle size falls downward through the plane screen 104, and the cow dung with larger particle size will flow backwards into the curved screen 105 for crushing. An upper crushing shaft 106 is rotatably connected to the flipping machine box 1, and a plurality of blades for crushing cow dung are fixed to the upper crushing shaft 106. The upper crushing shaft 106 is used to crush the cow dung in the curved screen 105.

[0028] When it is necessary to perform a turning operation, the crawler walking mechanism 101 is controlled to drive the turning machine box 1 to move along the length direction of the cow dung accumulation, and the turning shaft 102 is controlled to rotate counterclockwise. The rotation direction described in this specification refers to the perspective from right to left, and the direction of the turning shaft 102 is forward. The turning claw 103 will throw the cow dung in front backward onto the flat screen 104, and the flat screen 104 will screen the cow dung. The cow dung with qualified particle size will fall downward through the flat screen 104, and the cow dung with larger particle size will flow along the flat screen 104 to the curved screen 105. The upper crushing shaft 106 will crush the cow dung in the curved screen 105, and the crushed cow dung will fall downward after being screened by the curved screen 105.

[0029] like Figure 2 , Figure 3 , Figure 5 and Figure 7As shown, it also includes a shaking mechanism for improving the screening efficiency of the plane screen 104, the shaking mechanism is installed on the flipping machine box 1, the shaking mechanism includes a front guide rod 3, a No. 1 spring 301, a force rod 302, a sun gear 303 and a lever 304, the inner side of the top wall of the flipping machine box 1 is symmetrically fixed with two front guide rods 3, the plane screen 104 is slidably connected to the two front guide rods 3, the front guide rod 3 is sleeved with a No. 1 spring 301, and the plane screen 104 will slide upward The No. 1 spring 301 is compressed, and the left end of the flat screen 104 is fixedly connected with a force rod 302. The force rod 302 passes through the left side wall of the flipping machine case 1, and the left side wall of the flipping machine case 1 is provided with a through hole for the force rod 302 to move up and down. The outer side of the left side wall of the flipping machine case 1 is rotatably connected to the sun gear 303, and a plurality of shifting rods 304 are fixedly connected to the side wall of the sun gear 303 in a circular array. When the sun gear 303 rotates, the shifting rod 304 will push the force rod 302 upward.

[0030] During the counterclockwise rotation of the sun gear 303, the lever 304 will push the force rod 302 upward, and the force rod 302 will drive the plane screen 104 to move upward, and the No. 1 spring 301 will be compressed. When the sun gear 303 continues to rotate, the lever 304 will be out of contact with the force rod 302, and then the plane screen 104 will reset downward under the action of its own gravity and the thrust of the No. 1 spring 301, so that during the rotation of the sun gear 303, the lever 304 and the No. 1 spring 301 drive the plane screen 104 to shake up and down, thereby improving the screening efficiency of cow dung.

[0031] like Figure 1-Figure 3 As shown, it also includes a mixing mechanism for turning the cow dung on the bottom layer, the mixing mechanism is installed on the turning and throwing machine box 1, the mixing mechanism includes a shovel plate 4, a conveyor belt 401, a mixing shaft 402, a mixing claw 403, a supporting plate 404 and a lower pulley group 405, the inner sides of the left and right side walls of the turning and throwing machine box 1 are fixedly connected with the shovel plate 4 and the supporting plate 404, the shovel plate 4 is a front low and rear high inclined design, the left and right side walls of the turning and throwing machine box 1 are connected with rollers of the conveyor belt 401, the conveyor belt 401 is located between the left and right side walls of the turning and throwing machine box 1, and the conveyor belt 401 is located between the shovel plate 4 and the supporting plate 404 The conveyor belt 401 is used to transport the cow dung backwards, and the left and right side walls of the turning and throwing machine box 1 are connected to a mixing shaft 402 that rotates together. A plurality of mixing claws 403 are fixedly connected to the mixing shaft 402 in a ring array. The mixing claws 403 are used to throw the cow dung backwards. The turning and throwing shaft 102, the conveyor belt 401 and the mixing shaft 402 are connected through a lower pulley group 405. The lower pulley group 405 consists of two single-groove pulleys, one double-groove pulley and two belts. The single-groove pulley is fixedly connected to the rotating shafts of the turning and throwing shaft 102 and the mixing shaft 402, and the double-groove pulley is fixedly connected to a roller of the conveyor belt 401.

[0032] In order to prevent the turning claw 103 from colliding with the ground, the turning shaft 102 of the prior art is usually adjusted higher. After the turning shaft 102 is adjusted higher, the turning claw 103 is difficult to contact with the cow dung on the bottom layer, resulting in the cow dung on the bottom layer being difficult to be effectively turned over and there is a situation of insufficient turning. Therefore, it is necessary to solve this defect; when the turning shaft 102 rotates counterclockwise, the conveyor belt 401 and the mixing shaft 402 are also driven to rotate counterclockwise through the lower pulley group 405, and the cow dung screened and fallen by the curved screen 105 and the flat screen 104 will flow to the conveyor belt 401, while the cow dung on the bottom layer is still on the ground. On the surface, the shovel plate 4 will scoop up the cow dung on the bottom layer during the movement of the turning box 1. As the turning box 1 moves, the cow dung will move to the conveyor belt 401, and the conveyor belt 401 will transport the screened cow dung and the cow dung on the bottom layer toward the supporting plate 404 to achieve preliminary mixing of the two. The mixing shaft 402 will rotate counterclockwise, and the mixing claw 403 will throw the cow dung that flows onto the supporting plate 404 and is transported to the rear end of the conveyor belt 401 backwards during rotation, so that the two types of cow dung can be further mixed in the process of throwing up, which not only ensures that the cow dung can be fully turned over, but also helps to improve the uniformity of cow dung fermentation.

[0033] Embodiment 2: Based on embodiment 1, Figure 4-Figure 6 As shown, it also includes a pushing mechanism for pushing the cow dung on the bottom layer onto the shovel plate 4. The pushing mechanism is connected to the shaking mechanism. The pushing mechanism includes a pushing barrel 5, a pushing plate 501, a pushing gear 502 and a power gear 503. The left and right side walls of the turning machine case 1 are connected to the pushing barrel 5 for rotation. The pushing barrel 5 is located on the upper side of the shovel plate 4. The pushing plate 501 is fixedly connected to the pushing barrel 5. The pushing plate 501 is used to push the cow dung. The pushing gear 502 is fixedly connected to the rotating shaft of the pushing barrel 5. The power gear 503 is fixedly connected to the rotating shaft of the sun gear 303. The power gear 503 and the pushing gear 502 are meshed.

[0034] When the sun gear 303 rotates, it will drive the push barrel 5 to rotate clockwise through the power gear 503 and the push gear 502. During the clockwise rotation of the push barrel 5, the push plate 501 will push the cow dung on the shovel plate 4 upwards, so that the cow dung can be better moved to the conveyor belt 401.

[0035] like Figure 7 and Figure 8As shown, it also includes a crushing mechanism for crushing cow dung on the bottom layer, the crushing mechanism is connected to the push barrel 5, the crushing mechanism includes a leakage screen 7, a fixed seat 701, a lower crushing shaft 702, a driven gear 703 and an active gear ring 704, the push barrel 5 is equipped with a leakage screen 7, the leakage screen 7 is used to scrape and screen cow dung, two fixed seats 701 are symmetrically fixed to the push barrel 5, the two fixed seats 701 are connected to the lower crushing shaft 702 for common rotation, a plurality of blades for crushing cow dung are fixed to the lower crushing shaft 702, the lower crushing shaft 702 is used to crush the scraped cow dung, the driven gear 703 is fixed to the rotating shaft of the lower crushing shaft 702, the active gear ring 704 is fixed to the inner side of the left side wall of the flipping machine case 1, and the driven gear 703 and the active gear ring 704 are meshed.

[0036] When the pushing barrel 5 rotates clockwise, the leakage screen 7 will scrape the cow dung on the bottom layer and push the cow dung onto the shovel plate 4. Since the driven gear 703 and the active gear ring 704 are engaged, the lower crushing shaft 702 will rotate during the revolution of the pushing barrel 5. The rotating lower crushing shaft 702 will crush the cow dung scraped by the leakage screen 7.

[0037] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, it also includes a screening mechanism for driving the leakage screen 7 to shake, the screening mechanism is connected to the leakage screen 7, the screening mechanism includes a slide 8, a shaking material frame 801, a third spring 802, a shaking material plate 803, a main push block 804 and an auxiliary push block 805, a slide 8 is axially provided on the pushing cylinder 5, the shaking material frame 801 is slidably connected in the slide 8, the leakage screen 7 is fixedly connected to the shaking material frame 801, and a third spring 802 is sleeved on the guide rod of the shaking material frame 801. When the frame 801 slides axially, the No. 3 spring 802 will be compressed, and a shaking plate 803 is fixedly connected to the inner side of the right side wall of the flipping machine case 1. The rotating shaft of the pushing cylinder 5 passes through the middle of the shaking plate 803, and a plurality of main pushing blocks 804 are fixedly connected in a ring array at one end of the shaking plate 803 close to the pushing cylinder 5, and an auxiliary pushing block 805 is fixedly connected to one end of the leakage screen 7 close to the main pushing block 804. The main pushing block 804 is used to squeeze the auxiliary pushing block 805 to drive the leakage screen 7 to slide axially.

[0038] When the pushing cylinder 5 drives the leakage screen 7 to rotate, the main pushing block 804 will intermittently squeeze the auxiliary pushing block 805, and drive the leakage screen 7 to shake with the cooperation of the third spring 802, so that the crushed cow dung can leak out through the leakage screen 7, so as to reduce the resistance of the leakage screen 7 and the workload of the lower crushing shaft 702. The pushing plate 501 will push the cow dung screened by the leakage screen 7 onto the conveyor belt 401, and the cow dung with larger particle size can continue to be crushed. By shaking the leakage screen 7, the fluidity of the cow dung can be increased to avoid the cow dung not flowing and causing the lower crushing shaft 702 to only crush the cow dung within a fixed range.

[0039] Embodiment 3: Based on embodiment 2, Figure 1-Figure 3 As shown, it also includes a lifting mechanism for pushing the cow dung in the cambered screen 105 upward to the crushing shaft 106. The lifting mechanism is connected to the pushing barrel 5. The lifting mechanism includes a turntable 6, a lifting plate 601, a lifting rod 602, a rear guide rod 604 and a No. 2 spring 605. The rotating shaft of the pushing barrel 5 is fixedly connected to the turntable 6. A lifting plate 601 is fixedly connected to the turntable 6. The outer end of the lifting plate 601 is a curved surface. The cambered screen 105 is connected to the lifting rod 602. The lifting plate 601 is used to squeeze the lifting rod 602 upward. Two rear guide rods 604 are symmetrically fixed to the inner side of the top wall of the flipping machine box 1. The cambered screen 105 is slidably connected to the two rear guide rods 604. The rear guide rods 604 are sleeved with a No. 2 spring 605. When the cambered screen 105 slides upward, the No. 2 spring 605 will be compressed.

[0040] When the push barrel 5 rotates, it will drive the turntable 6 to rotate synchronously. When the turntable 6 rotates, the lifting plate 601 will intermittently squeeze the lifting rod 602 upward, so that the lifting rod 602 drives the curved screen 105 to move upward. The operating radius of the curved screen 105 and the upper crushing shaft 106 has an end distance, so that cow dung with larger particle size can smoothly enter the curved screen 105. The curved screen 105 will drive the cow dung upward to move within the operating radius of the upper crushing shaft 106 for crushing, and the No. 2 spring 605 is compressed. When the lifting plate 601 gradually cancels the squeezing of the lifting rod 602, the curved screen 105 will reset downward under the push of gravity and the No. 2 spring 605, so as to continue to collect cow dung with larger particle size.

[0041] like Figure 3 As shown, the lifting mechanism also includes a lifting block 603. A plurality of lifting blocks 603 are fixedly connected to the turntable 6. The lifting blocks 603 are used to slightly squeeze the lifting rod 602 upward.

[0042] During the rotation of the lifting plate 601, the lifting block 603 will intermittently lift the lifting rod 602 slightly upward, so that the curved screen 105 can shake slightly after being reset downward, so that the cow dung in the curved screen 105 can be quickly screened.

[0043] like Figure 3 As shown, it also includes a baffle plate 9, which is slidably connected to the side wall of the turning machine box 1. The upper side of the baffle plate 9 is fixedly connected to the curved screen 105, and the lower side of the baffle plate 9 is fixedly connected to the lifting rod 602. The baffle plate 9 is used to prevent the cow dung on the flat screen 104 from flowing onto the curved screen 105.

[0044] The lifting rod 602 drives the curved screen 105 to move upward through the baffle plate 9. When the curved screen 105 moves upward, the baffle plate 9 will move to the upper side of the flat screen 104, so that the cow dung on the flat screen 104 cannot continue to flow into the curved screen 105, which helps to ensure that the flat screen 104 fully screens the cow dung and prevents a large amount of cow dung from entering the crushing operation range and causing poor operation.

[0045] like Figure 2 , Figure 3 and Figure 6 As shown, it also includes an upper guide plate 10 and a lower guide plate 11 for guiding cow dung. The upper guide plate 10 is fixedly connected to the inner side of the top wall of the turning machine box 1, and the upper guide plate 10 is located on the upper side of the flat screen 104. The upper guide plate 10 is used to guide the thrown cow dung so that the cow dung falls on the flat screen 104. The lower guide plates 11 are fixedly connected to the inner sides of the left and right side walls of the turning machine box 1, and the lower guide plates 11 are located on the lower side of the flat screen 104.
