[0025] First, it should be noted that the directional terms such as up, down, left, right, front, and back mentioned in this utility model are only descriptions based on the accompanying drawings for ease of understanding, and are not intended to limit the technical solution or the scope of protection claimed in this utility model.
[0026] like Figures 1 to 10 The present invention discloses a specific embodiment of a walnut and grain crushing and breaking machine, including a frame 1, a first motor 2 fixed on the frame 1, and a crushing cylinder 3 with its opening facing downward. Four symmetrically distributed roller assemblies are provided at the bottom of the frame 1 for easy movement, and the roller assemblies are integrated with a braking mechanism to keep the frame 1 stable during operation. A first synchronous pulley 21 is fixed on the output shaft of the first motor 2. A crushing turret 4 is provided in the crushing cylinder 3, and the crushing turret 4 is provided with a rotating shaft 41 and multi-layer cutter discs 42 fixed axially at intervals on the rotating shaft 41. The rotating shaft 41 passes through the top wall of the crushing cylinder 3 and is mounted on the frame 1 through bearings. A second synchronous pulley 43 is fixed at the upper end of the rotating shaft 41, and a transmission belt 5 is provided between the second synchronous pulley 43 and the first synchronous pulley 21. The cutter discs 42 are provided with blades 421 distributed circumferentially. A feed hopper 6 is provided on one side of the cylinder 3, communicating with its inner cavity and located above the cutter discs 42.
[0027] The above configuration constitutes a simple, easy-to-operate, highly efficient, and effective crushing and grinding machine. In practical applications, after starting the first motor 2, walnut kernels are fed from the feed hopper 6 into the crushing cylinder 3. During the walnut kernels' descent, they are repeatedly cut by multiple layers of blades 42, achieving the crushing purpose. The crushed walnut powder is output through the lower end of the crushing cylinder 3. This invention improves the stability and ease of operation by setting up the frame 1. By setting up the crushing turret 4 and arranging multiple layers of blades 42 spaced axially, the crushing effect and efficiency are improved. It is particularly suitable for items with high moisture or oil content and can fully meet the needs of large-scale industrial production. It should be noted that this invention is not limited to walnut kernel crushing; it is also applicable to grains and cereals.
[0028] As an optimization, this specific embodiment sets fourteen cutter discs 42, and staggers the blades 421 of adjacent cutter discs 42 in the circumferential direction. A first connecting rod 422 distributed circumferentially is provided between even-numbered layers of cutter discs 42, and a second connecting rod 423 distributed circumferentially is provided between odd-numbered layers of cutter discs 42. The first connecting rod 422 and the second connecting rod 423 are fixedly connected to their respective blades 421, and the distance from the first connecting rod 422 to the center of the cutter disc 42 is greater than the distance from the second connecting rod 423 to the center of the cutter disc 42. This structure improves the crushing effect through the staggered arrangement of the blades 421, and by setting the first connecting rod 422 and the second connecting rod 423, it improves structural stability and enhances the crushing effect and efficiency by utilizing the impact of the first connecting rod 422 and the second connecting rod 423 on the crushed material. As an optimized solution, this specific embodiment employs the following assembly method for the pulverizing turret 4: a tapered collar 411 and a limiting strip 412 located below the collar 41 and along the axial direction are provided on the rotating shaft 41, so that the cutter disc 42 is fitted onto the rotating shaft 41 from bottom to top. A first limiting groove 424 that cooperates with the limiting strip 412 is provided on the cutter disc 42. A positioning ring 44 fitted onto the rotating shaft 41 is provided between adjacent cutter discs 42, and a second limiting groove 441 that cooperates with the limiting strip 412 is provided on the positioning ring 44. A locking nut 45 is installed at the lower end of the rotating shaft 41. This pulverizing turret 4 features a simple structure, easy preparation, convenient assembly and disassembly, and stable and reliable operation. Accordingly, in this specific embodiment, the first connecting rod 422 and the second connecting rod 423 are installed and fixed in the following way: both the first connecting rod 422 and the second connecting rod 423 adopt a screw structure, allowing the first connecting rod 422 to pass through each blade 421 at a corresponding position, and screwing a first fixing nut 425 onto the upper and lower sides of each blade 421; the second connecting rod 423 passes through each blade 421 at a corresponding position, and screwing a second fixing nut 426 onto the upper and lower sides of each blade 421. It should be noted that this utility model is not limited to setting the cutter head 42 with fourteen layers; other numbers can be set according to actual needs. Generally, setting ten or more layers is sufficient to meet the requirements.
[0029] As an optimization, this embodiment fixes a receiving box 7 located below the crushing cylinder 3 on the frame 1 to facilitate the collection of crushed materials. For convenient conveying and bagging during mass production, this embodiment uses an arc-shaped plate structure for the bottom wall of the receiving box 7, with a discharge port at one end. The receiving box 7 contains a material pushing device 8, which includes a support shaft 81 and spiral blades 82 fixed to the support shaft 81. Both ends of the support shaft 81 pass through the receiving box 7 and are mounted on the frame 1 via bearing seats 11. One end of the support shaft 81 is connected to a second motor 9. This configuration, when the second motor 9 is started, continuously pushes the crushed material to the discharge port through the rotation of the spiral blades 82. The material is then received and sealed in a packaging bag at the discharge port. In practical applications, to facilitate material reception and bagging, this invention also provides an inclined discharge pipe 71 at the bottom of the receiving box 7, corresponding to the discharge port.
[0030] In a specific embodiment, this invention adopts a split structure for both the crushing cylinder 3 and the feeding hopper 6 to facilitate manufacturing and disassembly. Specifically, the crushing cylinder 3 includes an end cap 31 fixed to the frame 1 and a cylinder 32 fixed to the end cap 31 by screws. The feeding hopper 6 includes a lower hopper 61 fixed to the end cap 31 by welding and an upper hopper 62 fixed to the lower hopper 61 by screws. In another specific embodiment, this invention improves protection and safety by providing a protective box 12 on the frame 1 and around the transmission belt 5. A support plate 13 is also provided on the frame 1 and below the second motor 9 to fix the second motor 9 to the support plate 13. In practical applications, to prevent material leakage from the connection point, this invention provides bushings at the positions where the rotating shaft 41 passes through the crushing cylinder 3 and the support shaft 81 passes through the receiving box 7.
[0031] The above embodiments are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications made by those skilled in the art based on the technical solution of the present utility model without departing from the design concept of the present utility model shall fall within the scope of protection defined by the claims of the present utility model.
