Obviously, the described embodiments are only 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.

[0036] The present invention provides a technical solution of a crushing mixer for producing organic fertilizer:

[0037] Example:

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it comprises a first barrel body 1, a second barrel body 2 is arranged at the bottom of the first barrel body 1, a third barrel body 3 is arranged at the bottom of the second barrel body 2, a discharge barrel 4 is connected to the bottom of the third barrel body 3, a fixing frame 6 is connected to the outer wall of the third barrel body 3, and one end of the fixing frame 6 is connected to a base 7;

[0039] The outer wall of the first barrel 1 is connected to a support 14, a motor 15 is arranged on the top of the support 14, a first rotating rod 18 is arranged on one side of the motor 15, a motor rotating rod 16 is arranged on the top of the motor 15, one end of the first rotating rod 18 is connected to a driving gear 19, and the outer rings of the motor rotating rod 16 and the first rotating rod 18 are jointly sleeved with a first transmission structure 17;

[0040] An L-shaped connecting frame 58 is connected to one side of the top of the first barrel 1. The inner cavity of the L-shaped connecting frame 58 is rotatably connected to a sleeve 21 through a bearing. One end of the sleeve 21 is connected to a driven gear 20. The bottom end of the sleeve 21 is provided with a first slot 22.

[0041] The inner wall of the third barrel 3 is connected with a bracket 29, one end of the bracket 29 is connected with a support plate 28, the bottom of the bracket 29 is connected with a reinforcing plate 30, the top of the support plate 28 is connected with a cylinder 27, the top of the cylinder 27 is rotatably connected with a connecting column 26 through a bearing, the top of the connecting column 26 is connected with a roller 25, and the top of the roller 25 is connected with a first clamping block 23;

[0042] The inner cavity of the first barrel 1 is provided with a rolling groove 52, and the inner wall of the rolling groove 52 and the outer wall of the roller 25 are both provided with a plurality of rolling rods 51 distributed in a ring shape. A first feeder 53 is provided on the side of the top of the first barrel 1 opposite to the L-shaped connecting frame 58, and a second feeder 54 is provided on the side of the top of the second barrel 2.

[0043] The roller 25 and the roller groove 52 are both conical, the first clamping block 23 is movably connected to the first clamping groove 22, and the driving gear 19 and the driven gear 20 are meshed for transmission.

[0044] In the present embodiment, since the shapes of the roller 25 and the rolling groove 52 are both cones with the top surface smaller than the bottom surface, and the diameter of the bottom end of the roller 25 is consistent with the diameter of the bottom end of the rolling groove 52, when the roller 25 continues to move upward, the gap between the outer wall of the roller 25 and the rolling groove 52 will gradually become smaller. When the bottom end of the roller 25 and the bottom end of the rolling groove 52 are at the same horizontal plane, the degree of crushing of the material reaches the minimum value of the equipment. Thus, the degree of crushing of the material by the equipment can be controlled, specifically: the motor rotating rod 16 is driven to rotate by the motor 15, and then the motor rotating rod 16 drives the first rotating rod 18 to rotate through the first transmission structure 17. At this time, the first rotating rod 18 drives the driven gear 20 to rotate through the driving gear 19, and then the driven gear 20 drives the first block 23 to rotate through the sleeve 21, thereby driving the roller 25. It rotates in the rolling groove 52, at this time, the material is put into the first barrel 1 from the first feeder 53, and then the material slides down along the edge of the roller 25 until the material is between the roller 25 and the rolling groove 52. Under the action of the rolling rod 51, the purpose of crushing the material can be achieved. When the degree of crushing needs to be adjusted, the connecting column 26 is driven upward by the cylinder 27, and then the connecting column 26 can drive the roller 25 to move upward to achieve the purpose of reducing the gap between the roller 25 and the rolling groove 52. Conversely, the degree of crushing of the material can be increased. It is more flexible to use, and different degrees of crushing can be performed on different materials, and the degree of crushing is controllable and adjustable; when the roller 25 is driven to move upward, the first block 23 connected to its top continues to penetrate into the first groove 22 to ensure that the sleeve 21 and the first block 23 are always in a linkage state.

[0045] Among them, Figure 5 As shown, a first spring 24 is disposed in the inner cavity of the first clamping slot 22 , and the first spring 24 is located above the first clamping block 23 .

[0046] In this embodiment, the first spring 24 is used to apply pressure to the first block 23 to offset the lift generated by the crusher 25 when it is crushing the material or the vibration of the equipment during operation, thereby reducing the burden on the cylinder 27 and preventing the cylinder 27 from being damaged by the pull of the upward and downward forces.

[0047] Among them, Figure 1 and Figure 2 As shown, the outer wall of the discharge barrel 4 is connected to an L-shaped connecting rod 12, the inner cavity of the base 7 is connected to a fixing rod 8, the outer ring of the fixing rod 8 is rotatably connected to a hydraulic cylinder 9, one end of the hydraulic cylinder 9 is rotatably connected to a first connecting block 10, the end of the first connecting block 10 is connected to a cover plate 5, the outer wall of the cover plate 5 is connected to a second connecting block 11, the second connecting block 11 is rotatably connected to the L-shaped connecting rod 12, and the cover plate 5 is located below the discharge barrel 4.

[0048] In this embodiment, after the hydraulic cylinder 9 is started, the cover plate 5 can be driven to rotate through the first connecting block 10. At this time, the cover plate 5 makes a circular motion with the second connecting block 11 as the center, and then the discharge barrel 4 is opened or closed through the cover plate 5, thereby achieving the purpose of controlling the length of time the material is processed in the equipment.

[0049] Among them, Figure 2 , Figure 4 and Figure 6 As shown, the outer ring of the connecting column 26 is annularly distributed with multiple first stirring rods 31, one side of the first stirring rod 31 is provided with multiple stirring blades 32, the first stirring rod 31 is located in the inner cavity of the third barrel 3, and one end of the first stirring rod 31 is fixedly connected to the bottom of the roller 25.

[0050] In this embodiment, when the roller 25 rotates, the multiple first stirring rods 31 connected to the bottom thereof and the multiple stirring blades 32 arranged on one side of the first stirring rods 31 rotate simultaneously in the third barrel 3. The material fed by the first feeder 53 will fall into the third barrel 3 after being crushed, and the material to be mixed fed by the second feeder 54 will also enter the third barrel 3. Driven by the first stirring rods 31 and the stirring blades 32, the purpose of uniformly mixing and stirring a variety of materials can be achieved.

[0052] In this embodiment, when the first stirring rod 31 rotates, the fixed plate 33 connected to one side thereof drives the connecting tube 34 to rotate. At this time, the connecting tube 34 can drive the scraper 38 to rotate through the T-shaped connecting rod 37, and then the scraper 38 is used to scrape off the material attached to the inner wall of the third barrel 3, so as to facilitate cleaning of the equipment and avoid waste of material; the second spring 36 is used to apply pressure to the scraper 38 so that the edge of the scraper 38 can always fit with the inner wall of the third barrel 3, thereby ensuring that the scraping of the material is more thorough, and because the T-shaped connecting rod 37 is connected to the fixed plate 33 through the second spring 36, the scraper 38 causes less damage to the inner wall of the third barrel 3 when scraping the material, and it can avoid the scraper 38 being worn out under long-term use, and the gap between the scraper 38 and the third barrel 3, resulting in incomplete scraping of the material.

[0057] The first transmission structure 17 , the second transmission structure 41 and the third transmission structure 46 all include a first gear 01 , a second gear 02 and a toothed belt 03 . The toothed belt 03 is sleeved on the outer rings of the first gear 01 and the second gear 02 . The first gear 01 and the second gear 02 are linked by the toothed belt 03 .
