Description

Technical Field

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

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

[0003] Although the turning and throwing machines in the prior art can break up cow dung through the turning and throwing action, in actual work, affected by factors such as operation methods, material humidity and density, only large pieces of cow dung can be broken up, while small pieces of cow dung are thrown backward, that is, small pieces of cow dung are difficult to be effectively broken up;

[0004] Among the existing related technical solutions, four Chinese patents with patent publication numbers CN216919059U, CN221217690U, CN217377740U and CN107056356B disclose four different turning and throwing machines. However, the four turning and throwing machines still achieve the function of breaking up cow dung through the turning and throwing action. Cow dung is very likely to form lumps during the composting fermentation process. For example, the steam generated during the composting process will cause cow dung to adhere to each other, the viscous substances produced by microbial decomposition will make cow dung stick together, and the cow dung at the bottom of the compost will be compressed into lumps due to greater pressure.

[0005] During the turning and throwing process, the lumps are likely to be affected by uneven forces, resulting in the outer part being broken up while there are still lumps remaining inside. And during the turning and throwing process, the lumps may collide or entangle with each other, further resulting in lumps remaining. The remaining cow dung lumps will not only reduce the uniformity of fermentation, but also reduce the efficiency of cow dung fermentation;

[0006] In addition, in order to avoid the turning and throwing components from colliding with the ground, the turning and throwing components are usually raised in position. After the position of the turning and throwing components is raised, it is difficult to contact the cow dung at the bottom layer, resulting in the cow dung at the bottom layer compressed into lumps being more difficult to be effectively turned and thrown, further reducing the uniformity and efficiency of cow dung fermentation;

[0007] Therefore, it is necessary to design a crawler type cow dung turning and throwing machine that can effectively avoid lump residues and can effectively turn and throw the cow dung at the bottom layer in view of the shortcomings of the existing turning and throwing machines that only break up cow dung through the turning and throwing action and there will be lump residues and the cow dung lumps at the bottom layer are difficult to be effectively turned and thrown.

[0019] The present invention has the following advantages: 1. This turning and throwing machine can screen the cow dung thrown up during the turning and throwing process, preventing the larger-sized cow dung from falling, and causing it to flow along the flat screen mesh into the arc-shaped screen mesh, where the upper crushing shaft crushes the cow dung in the arc-shaped screen mesh, solving the technical problem in the prior art that it is difficult for a turning and throwing machine to effectively break small pieces of cow dung;

[0020] 2. During the rotation of the sun gear, through the cooperation of the dial rod, the force-receiving rod, and the first spring, the flat screen mesh can be driven to reciprocate up and down, improving the screening efficiency of the flat screen mesh for cow dung;

[0021] 3.

And when the jacking plate and the jacking rod are out of contact, the jacking block will intermittently push the jacking rod slightly upward, causing the arc-shaped screen mesh to vibrate to improve the screening efficiency.

It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments.

[0034] Embodiment 1: A crawler-type cow dung turning and throwing machine, as Figures 1-3As shown in the figure, it includes a turning and throwing machine box 1, a crawler traveling mechanism 101, a turning and throwing shaft 102, turning and throwing claws 103, a flat screen 104, a curved screen 105, and an upper crushing shaft 106. A crawler traveling mechanism 101 is installed on the turning and throwing machine box 1, and the crawler traveling mechanism 101 is used to drive the turning and throwing machine box 1 to move. The turning and throwing shaft 102 is rotatably connected to the left and right side walls of the turning and throwing machine box 1, and a plurality of turning and throwing claws 103 are fixedly connected to the turning and throwing shaft 102 in an annular array. A flat screen 104 and a curved screen 105 are arranged in the turning and throwing machine box 1. The curved screen 105 is located behind the flat screen 104, and the flat screen 104 is inclined with the front end higher than the rear end. The turning and throwing claws 103 are used to throw cow dung backward onto the flat screen 104. The cow dung with qualified particle size falls downward through the flat screen 104, and the cow dung with larger particle size will flow backward into the curved screen 105 for crushing treatment. The upper crushing shaft 106 is rotatably connected to the turning and throwing machine box 1, and a plurality of blades for crushing cow dung are fixedly connected to the upper crushing shaft 106. The upper crushing shaft 106 is used to crush the cow dung in the curved screen 105.

[0035] When turning and throwing operation is required, control the crawler traveling mechanism 101 to drive the turning and throwing machine box 1 to travel along the length direction of the cow dung pile, and control the turning and throwing shaft 102 to rotate counterclockwise. The rotation direction described in this specification is the perspective view from right to left, and the direction where the turning and throwing shaft 102 is located is the front. The turning and throwing claws 103 will throw the cow dung in the front backward onto the flat screen 104. 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 into 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.

[0036] Such as 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.

[0037] 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.

[0038] like Figures 1-3 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.

[0039] In order to avoid the turning claws 103 of the turning machine in the prior art from colliding with the ground, the position of the turning shaft 102 is usually raised. However, after the position of the turning shaft 102 is raised, it is difficult for the turning claws 103 to contact the cow dung at the bottom layer, resulting in the cow dung at the bottom layer being difficult to be effectively turned over, and there is an insufficient turning situation. Therefore, it is necessary to solve this defect; when the turning shaft 102 rotates counterclockwise, it will drive the conveyor belt 401 and the mixing shaft 402 to rotate counterclockwise through the lower pulley group 405. The cow dung screened by the arc-shaped screen 105 and the flat screen 104 and falling down will flow onto the conveyor belt 401, while the cow dung at the bottom layer still remains on the ground. During the movement of the turning machine box 1, the shovel plate 4 will shovel up the cow dung at the bottom layer. As the turning machine box 1 moves, the cow dung will move onto the conveyor belt 401, and the conveyor belt 401 will convey the screened cow dung and the cow dung at the bottom layer together in the direction of the material supporting plate 404 to achieve the preliminary mixing of the two. The mixing shaft 402 will rotate counterclockwise, and when rotating, the mixing claws 403 will throw the cow dung flowing onto the material supporting plate 404 and conveyed to the rear end of the conveyor belt 401 backward, so that the two kinds of cow dung can be further mixed during the throwing process, which not only ensures that the cow dung can be fully turned over but also helps to improve the uniformity of the cow dung fermentation.

[0040] Embodiment 2: On the basis of Embodiment 1, as Figures 4-6 shown, it further includes a material pushing mechanism for pushing the cow dung at the bottom layer onto the shovel plate 4. The material pushing mechanism is connected to the shaking mechanism. The material pushing mechanism includes a material pushing cylinder 5, a material pushing plate 501, a material pushing gear 502, and a power gear 503. The left and right side walls of the turning machine box 1 are jointly rotatably connected with a material pushing cylinder 5. The material pushing cylinder 5 is located above the shovel plate 4. A material pushing plate 501 is fixedly connected to the material pushing cylinder 5. The material pushing plate 501 is used for pushing the cow dung. A material pushing gear 502 is fixedly connected to the rotating shaft of the material pushing cylinder 5. A power gear 503 is fixedly connected to the rotating shaft of the sun gear 303. The power gear 503 and the material pushing gear 502 are meshed.

[0041] When the sun gear 303 rotates, it will drive the material pushing cylinder 5 to rotate clockwise through the power gear 503 and the material pushing gear 502. During the clockwise rotation of the material pushing cylinder 5, the material pushing plate 501 will push the cow dung on the shovel plate 4 upward, so that the cow dung can better move onto the conveyor belt 401.

[0042] As Figure 7 and Figure 8As shown in the figure, it further includes a crushing mechanism for crushing the cow dung at the bottom layer. The crushing mechanism is connected to the material pushing cylinder 5. The crushing mechanism includes a leakage screening mesh 7, a fixed seat 701, a lower crushing shaft 702, a driven gear 703 and a driving gear ring 704. The leakage screening mesh 7 is installed on the material pushing cylinder 5. The leakage screening mesh 7 is used for scraping and screening the cow dung. Two fixed seats 701 are symmetrically fixedly connected to the material pushing cylinder 5. A lower crushing shaft 702 is rotatably connected between the two fixed seats 701. A plurality of blades for crushing the cow dung are fixedly connected to the lower crushing shaft 702. The lower crushing shaft 702 is used for crushing the scraped cow dung. A driven gear 703 is fixedly connected to the rotating shaft of the lower crushing shaft 702. A driving gear ring 704 is fixedly connected to the inner side of the left side wall of the turning and throwing machine box 1. The driven gear 703 and the driving gear ring 704 are meshed with each other.

[0043] When the material pushing cylinder 5 rotates clockwise, the leakage screening mesh 7 will scrape the cow dung at the bottom layer and push the cow dung onto the shovel plate 4. Since the driven gear 703 and the driving gear ring 704 are meshed with each other, during the revolution of the material pushing cylinder 5, the lower crushing shaft 702 will rotate. The rotating lower crushing shaft 702 will crush the cow dung scraped by the leakage screening mesh 7.

[0044] As Figure 3 , Figure 4 , Figure 7 and Figure 8 shown in the figure, it further includes a screening mechanism for driving the leakage screening mesh 7 to vibrate. The screening mechanism is connected to the leakage screening mesh 7. The screening mechanism includes a slideway 8, a vibrating material rack 801, a third spring 802, a vibrating material disk 803, a main pushing block 804 and a secondary pushing block 805. A slideway 8 is axially formed on the material pushing cylinder 5. A vibrating material rack 801 is slidably connected in the slideway 8. The leakage screening mesh 7 is fixedly connected to the vibrating material rack 801. A third spring 802 is sleeved on the guide rod of the vibrating material rack 801. When the vibrating material rack 801 slides axially, the third spring 802 will be compressed. A vibrating material disk 803 is fixedly connected to the inner side of the right side wall of the turning and throwing machine box 1. The rotating shaft of the material pushing cylinder 5 passes through the middle of the vibrating material disk 803. A plurality of main pushing blocks 804 are annularly and arrayedly fixedly connected to one end of the vibrating material disk 803 close to the material pushing cylinder 5. A secondary pushing block 805 is fixedly connected to one end of the leakage screening mesh 7 close to the main pushing block 804. The main pushing block 804 is used for squeezing the secondary pushing block 805 to drive the leakage screening mesh 7 to slide axially.

[0045] During the rotation of the material pushing cylinder 5 driving the material leakage screen 7, the main pushing block 804 will intermittently squeeze the secondary pushing block 805, and with the cooperation of the third spring 802, drive the material leakage screen 7 to vibrate, so that the crushed cow dung can leak through the material leakage screen 7, reducing the resistance of the material leakage screen 7 and the operating burden of the lower crushing shaft 702. The material pushing plate 501 will push the cow dung screened by the material leakage screen 7 onto the conveyor belt 401, and the cow dung with larger particle size can be continuously crushed. By vibrating the material leakage screen 7, the fluidity of the cow dung can also be increased, preventing the cow dung from not flowing and causing the lower crushing shaft 702 to only crush the cow dung within a fixed range.

[0046] Embodiment 3: On the basis of Embodiment 2, as Figures 1-3 shown, it further includes a lifting mechanism for pushing the cow dung in the arc-shaped screen 105 upward to the upper crushing shaft 106. The lifting mechanism is connected to the material pushing cylinder 5. The lifting mechanism includes a turntable 6, a lifting plate 601, a lifting rod 602, a rear guide rod 604, and a second spring 605. A turntable 6 is fixedly connected to the rotating shaft of the material pushing cylinder 5, and a lifting plate 601 is fixedly connected to the turntable 6. The outer end of the lifting plate 601 is a curved surface. A lifting rod 602 is connected to the arc-shaped screen 105. The lifting plate 601 is used to squeeze the lifting rod 602 upward. Two rear guide rods 604 are symmetrically and fixedly connected to the inner side of the top wall of the turning and throwing machine case 1. The arc-shaped screen 105 is slidably connected to the two rear guide rods 604, and a second spring 605 is sleeved on the rear guide rod 604. When the arc-shaped screen 105 slides upward, it will compress the second spring 605.

[0047] When the material pushing cylinder 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, causing the lifting rod 602 to drive the arc-shaped screen 105 to move upward. There is a certain distance between the operating radius of the arc-shaped screen 105 and the upper crushing shaft 106, enabling the cow dung with larger particle size to smoothly enter the arc-shaped screen 105. The upward movement of the arc-shaped screen 105 will drive the cow dung to move into the operating radius of the upper crushing shaft 106 for crushing, and the second spring 605 is compressed. When the lifting plate 601 gradually cancels the extrusion of the lifting rod 602, the arc-shaped screen 105 will reset downward under the action of gravity and the second spring 605 to facilitate the continuous collection of the cow dung with larger particle size.

[0048] As Figure 3 shown, the lifting mechanism further includes a lifting block 603. A plurality of lifting blocks 603 are fixedly connected to the turntable 6, and the lifting blocks 603 are used to slightly squeeze the lifting rod 602 upward.

[0049] During the rotation of the lifting plate 601, the lifting block 603 will intermittently lift the lifting rod 602 slightly upward, enabling the arc-shaped screen 105 to vibrate slightly after resetting downward, so as to quickly screen the cow dung in the arc-shaped screen 105.

[0050] As shown Figure 3 in the figure, it further includes a baffle 9. The baffle 9 is slidably connected to the side wall of the turning and throwing machine case 1. The upper side of the baffle 9 is fixedly connected to the arc-shaped screen 105, and the lower side of the baffle 9 is fixedly connected to the lifting rod 602. The baffle 9 is used to block the cow dung on the flat screen 104 from flowing onto the arc-shaped screen 105.

[0051] The lifting rod 602 drives the arc-shaped screen 105 to move upward through the baffle 9. After the arc-shaped screen 105 moves upward, the baffle 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 arc-shaped screen 105. This not only helps to ensure that the flat screen 104 fully screens the cow dung, but also can prevent a large amount of cow dung from entering the crushing operation range and causing poor operation.

[0052] As shown Figure 2 in Figure 3 Figures Figure 6 and

[0053] it further includes an upper guide plate 10 and a lower guide plate 11 for guiding the cow dung. The upper guide plate 10 is fixedly connected to the inner side of the top wall of the turning and throwing machine case 1. The upper guide plate 10 is located above the flat screen 104 and is used to guide the thrown-up cow dung so that the cow dung falls onto 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 and throwing machine case 1. The lower guide plates 11 are located below the flat screen 104 and are used to make the cow dung on the upper side flow onto the conveyor belt 401. The lower end of the baffle 9 does not contact the upper end of the lower guide plate 11, so it will not affect the backward flow of the cow dung along the lower guide plate 11.

[0054] As shown Figure 1 in Figure 2 Figures Figure 4 and Figure 5 Figures Figure 6As shown, it also includes a driving mechanism for driving the turning shaft 102, the upper crushing shaft 106 and the sun gear 303 to rotate, the driving mechanism includes a machine table 2, a motor 201, a main gear 202, a sub-gear 203, a transmission gear 204, an upper pulley group 205 and an upper gear 206. The outer side of the right side wall of the turning machine box 1 is fixedly connected to the machine table 2, the motor 201 is fixedly connected to the machine table 2, the main gear 202 is fixedly connected to the output shaft of the motor 201, the sub-gear 203 is fixedly connected to the right side of the rotating shaft of the turning shaft 102, and the main gear 206 is fixedly connected to the output shaft of the motor 201. 02 is meshed with the sub-gear 203, and the left side of the rotating shaft of the flipping shaft 102 is connected to the sun gear 303 through the upper pulley group 205. The upper pulley group 205 consists of two single-groove pulleys and a belt, one of which is fixedly connected to the rotating shaft of the sun gear 303, and the other is fixedly connected to the left side of the rotating shaft of the flipping shaft 102. A transmission gear 204 is also fixedly connected to the rotating shaft of the sun gear 303, and an upper gear 206 is fixedly connected to the rotating shaft of the upper crushing shaft 106, and the transmission gear 204 and the upper gear 206 are meshed.

[0055] When the motor 201 drives the flipping shaft 102 to rotate counterclockwise through the main gear 202 and the sub-gear 203, the flipping shaft 102 will drive the sun gear 303, the transmission gear 204 and the power gear 503 to rotate counterclockwise through the upper pulley group 205, and the transmission gear 204 will drive the upper crushing shaft 106 to rotate clockwise through the upper gear 206, and the power gear 503 will drive the push gear 502 to rotate clockwise.
