Description

Technical Field

[0001] The invention relates to the technical field of fungus cultivation, and in particular to a raw material crushing device for fungus cultivation. Background Art

[0002] There are various choices of raw materials for mushroom cultivation, mainly including waste from crops and forestry production, as well as some specific raw materials. Mixing different raw materials in proportion can effectively improve the growth environment of mushrooms. When waste from crops and forestry production is used as raw materials, crushing equipment is required to crush the raw materials.

[0003] Most crushing devices crush raw materials by setting up a crushing box and rotating crushing rollers in the crushing box. The crushing rollers rotate with each other to crush the raw materials. However, after the traditional crushing devices crush the raw materials, the raw materials are usually discharged directly from the discharge port of the crushing box. As long as the crushing rollers continue to crush the raw materials, broken raw materials will be continuously discharged from the discharge port of the crushing box. It is difficult for the staff to measure and transport the crushed raw materials according to the specifications. When different raw materials are subsequently used in proportion, the crushed raw materials need to be measured and proportioned again, which increases the workload and affects the work efficiency.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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] like Figure 1-8 As shown, a raw material crushing device for mushroom cultivation comprises a workbench 1 and a crushing box 2 fixedly arranged on the upper end of the workbench 1, a feed hopper 3 is fixedly arranged on the upper end of the crushing box 2, two crushing rollers 13 are rotatably arranged inside the crushing box 2, one end of the rotating shaft of the two crushing rollers 13 passes through the crushing box 2 and is provided with gears meshing with each other, a first motor 4 for driving one of the crushing rollers 13 to rotate is arranged on one side of the crushing box 2, a material drop opening 6 matched with the output end of the crushing box 2 is opened on the surface of the workbench 1, and a conveying mechanism matched with the material drop opening 6 for conveying crushed materials is arranged at the lower end of the workbench 1. When in use, the raw material to be crushed is added into the crushing box 2 from the feed hopper 3, and the raw material is crushed through the rotation and cooperation of the two crushing rollers 13, and the crushed raw material falls into the conveying mechanism through the material drop opening 6, and is conveyed and transferred as the conveying mechanism works;

[0037] The conveying mechanism includes a conveying pipe 5 and a spiral conveying rod rotatably arranged inside the conveying pipe 5. A second motor 7 for driving the spiral conveying rod to rotate is fixedly arranged on the outside of the conveying pipe 5. A discharge pipe 9 is fixedly arranged on one side of the lower end of the conveying pipe 5. A feed shell 8 is fixedly arranged on one side of the upper end of the conveying pipe 5. A connecting frame 10 matching with the blanking opening 6 is fixedly arranged on the upper end of the feed shell 8. The connecting frame 10 is fixedly connected to the lower end surface of the workbench 1 by bolts. A metering component for assisting the quantitative conveying of crushed materials is arranged inside the feed shell 8. When in use, the crushed raw materials enter the conveying pipe 5. As the spiral conveying rod rotates, the raw materials are conveyed to the discharge pipe 9 and discharged.

[0038] Further, the metering assembly includes a partition 17 fixedly arranged in the middle of the feed shell 8 and end plates 18 respectively fixedly arranged at both ends of the inner wall of the feed shell 8. The feed shell 8 is divided into two feed chambers by the partition 17. A movable plate 11 matching the two feed chambers is slidably arranged inside the connection frame 10. Pull ropes 21 are fixedly arranged on both sides of the movable plate 11. A sliding chamber is opened at the lower end of the two end plates 18. A sliding plate 19 is slidably arranged in the sliding chamber. The lower ends of the two sliding plates 19 are respectively fixedly provided with baffle plates matching the two feed chambers. 16, the inner walls of the two slide cavities are provided with slide grooves and a sliding block 23 is slidably arranged in the slide grooves, the sliding block 23 is connected to the inner bottom surface of the slide groove by a compression spring 24, one side of the two sliding plates 19 is fixedly provided with a hinge seat matched with the sliding block 23, and both sides of the feed shell 8 are respectively provided with a restraining member for restraining the baffle plate 16 to flip downward. When in use, the moving plate 11 is first located at the upper end of one of the feed cavities so that the upper end of the feed cavity is in a closed state, and the upper end of the other feed cavity is in an open state (refer to the attached manual Figure 4 With attached Figure 5 ), at this time, the crushed raw materials will fall into the open feed chamber. Due to the obstruction of the baffle plate 16, the raw materials will gradually gather in the feed chamber. As the materials gradually gather, under the action of gravity, the baffle plate 16 will move downward, and the downward movement of the baffle plate 16 will drive the sliding plate 19 to move downward, thereby achieving the effect of storing the raw materials in the feed chamber for metering.

[0039] Further, the restraining member includes a U-shaped bending rod 22 and a shell 30 fixedly arranged on the outside of the feed shell 8, one end of the U-shaped bending rod 22 is movable through the connecting frame 10, and the other end of the U-shaped bending rod 22 is movable through the sliding cavity and is provided with a restraining block 27, one end of the restraining block 27 is in contact with the surface of the sliding plate 19, and the surface of the sliding plate 19 is provided with a restraining groove 29 that matches the restraining block 27, and the other end of the restraining block 27 is connected to the inner wall of the sliding cavity through a connecting spring 26, and a winding roller 34 that matches the pull rope 21 is rotatably arranged inside the shell 30, and a third motor 31 for driving the winding roller 34 to rotate is fixedly arranged on the outside of the shell 30, and the third motor 31 is non-self-locking The outer side of the motor and the housing 30 is fixedly provided with a touch pressure switch 32 that cooperates with the U-shaped bending rod 22. The touch pressure switch 32 is electrically connected to the third motor 31. Electromagnets 33 are fixedly embedded at both ends of the inner wall of the connecting frame 10. Iron sheets 12 that cooperate with the electromagnets 33 are fixedly embedded on both sides of the movable plate 11. The two electromagnets 33 are electrically connected to the touch pressure switches 32 on the opposite sides respectively. When in use, the sliding plate 19 moves downward, which will gradually align the constraint groove 29 with the constraint block 27. When the constraint block 27 is aligned with the constraint groove 29, the constraint block 27 is stuck in the constraint groove 29 under the reset action of the connecting spring 26. At this time, the baffle plate 16 cannot continue to move downward. The U-shaped bending rod 22 is moved, that is, the feed chamber is filled with raw materials, so that the raw materials measured each time are the storage amount when the feed chamber is fully loaded. When the constraint block 27 is stuck in the constraint groove 29, the U-shaped bending rod 22 is driven to move and squeeze the touch switch 32. The touch switch 32 is squeezed to rotate the third motor 31 connected thereto, and the electromagnet 33 connected thereto is powered off, thereby releasing the adsorption of the iron sheet 12 at one end of the movable plate 11. The rotation of the third motor 31 drives the winding roller 34 to rotate to reel in the pull rope 21, thereby pulling the movable plate 11 to move and close the upper end of the feed chamber that was originally opened. When the upper end of the feed chamber is closed, the movement of the movable plate 11 will cause the iron sheet 12 at the other end to contact with the other end. An electromagnet 33 is adsorbed, and during this process, the movable plate 11 squeezes the U-shaped bent rod 22, so that the movement of the U-shaped bent rod 22 drives the constraint block 27 to disengage from the constraint groove 29, releasing the squeezing of the touch pressure switch 32, and the third motor 31 stops working. At this time, the baffle plate 16 is no longer constrained and will flip downward to discharge the material, so that the raw materials measured in the feed chamber are discharged into the conveying pipe 5. Due to the movement of the movable plate 11, the upper end of the originally closed feed chamber will be opened. At this time, the crushed raw materials fall into the feed chamber for metering. Similarly, when the feed chamber is full, the movable plate 11 will move in the opposite direction, so as to achieve the effect of metering the two feed chambers in turn.

[0040] Furthermore, the side walls of the connection frame 10 are respectively provided with installation cavities, inside which guide rollers 20 cooperating with the pull rope 21 are rotatably provided, thereby effectively ensuring the smoothness of the movement of the pull rope 21, reducing the friction and wear of the pull rope 21, and increasing the service life of the pull rope 21.

[0041] Furthermore, a ball 28 that matches the surface of the sliding plate 19 is rotatably embedded on the surface of the restraining block 27 , and the friction resistance is effectively reduced through the rolling contact between the ball 28 and the sliding plate 19 .

[0042] Furthermore, a guide rod 25 matched with the sliding block 23 is fixed in the sliding groove, and the sliding block 23 is slidably connected to the guide rod 25. Under the guiding action of the guide rod 25, the sliding block 23 slides stably to avoid twisting and deformation of the compression spring 24.

[0043] Furthermore, a support frame for supporting the conveying pipe 5 is provided at the lower end of the workbench 1, a protective cover 15 fixedly provided on the outer side of the crushing box 2 for covering the two gears, a side tooth plate 14 matched with the crushing roller 13 is fixedly provided on the inner wall of the crushing box 2, the support frame effectively ensures the firmness of the installation of the conveying pipe 5, the protective cover 15 covers the two meshing gears, effectively improving the safety during the gear meshing transmission process, the teeth on the surface of the crushing roller 13 and the teeth of the side tooth plate 14 are staggered, respectively, to improve the crushing efficiency of the raw materials.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
