Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a chicken bone crushing device. Background Technology

[0002] In the poultry processing industry, chicken bones, as a major by-product, often need to be pulverized before being used to produce bone meal and stock base. This process requires specialized pulverizing equipment. During pulverization, operators pour the chicken bones to be pulverized into the feed hopper, where they slide down into the pulverizing wheel due to gravity, thus achieving pulverization.

[0003] However, existing chicken bone crushing devices face the following drawbacks in practical applications: chicken bones have irregular shapes, high hardness and toughness, and often have residual muscle and connective tissue attached, resulting in poor material flowability. When traditional crushers use a continuous feeding mode, chicken bones are prone to bridging and clogging at the feed hopper inlet, forming blocked cavities, causing feeding interruptions, requiring frequent shutdowns for cleaning, and severely reducing production efficiency. Utility Model Content

[0004] In view of the above situation and in order to make up for the shortcomings of the existing technology, the purpose of this utility model is to provide a chicken bone crushing device that effectively solves the problem of easy clogging of the feed hopper in existing chicken bone crushing devices.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Depend on Figures 1 to 6 The device includes a main shell 1, with a feed bin 2 at the top. Rotary shafts 3, rotatable axially, are located on the front and rear sides of the main shell 1. Crushing wheels 4 are coaxially mounted on the shafts 3, and the two crushing wheels 4 can mesh with each other. Rotary columns 5, located above the crushing wheels 4 and axially aligned axially, are rotatably connected to the front and rear sides of the main shell 1. A baffle plate 6 is mounted on the column 5. A secondary gear 7 is coaxially mounted on the left end of the column 5, penetrating the main shell 1. A moving rod 8 is slidably connected to the left end of the main shell 1. Racks 9, located outside the secondary gear 7 and capable of meshing with it, are located on the front and rear sides of the upper end of the moving rod 8. A turntable 10, located below the moving rod 8, is coaxially mounted on the rear side of the shaft 3, penetrating the main shell 1. A protrusion 11, which can contact the moving rod 8, is mounted on the turntable 10.

[0027] To facilitate the sliding of chicken carcass bones, the feed hopper 2 is funnel-shaped, wider at the top and narrower at the bottom.

[0028] In order to make the rotating shaft 3 rotate, the rotating shaft 3 is rotatably connected to the main body shell 1. The left end of the rotating shaft 3 is provided with a main gear 12 located to the left of the turntable 10. The two main gears 12 can mesh with each other. The right end of the main body shell 1 is provided with a motor 13. The output shaft of the motor 13 is coaxially and fixedly connected to the rotating shaft 3 on the front side.

[0029] To facilitate the movement of the movable rod 8, the main body shell 1 has sliding grooves 14 on the front and rear sides of the left end, and the right end of the movable rod 8 is provided with a slider 15 that can slide in the sliding grooves 14.

[0030] To facilitate the resetting of the movable rod 8, a reset plate 16 is provided at the left end of the main body shell 1, located above the movable rod 8. The reset plate 16 is connected to the movable rod 8 via a spring 17.

[0031] To facilitate the collection of the crushed material, a groove is provided at the front end of the main shell 1, and a collection box 18 is placed in the groove.

[0032] To prevent material spillage, guide plates 19 are respectively provided on the front and rear sides of the main body shell 1, located between the crushing wheel 4 and the baffle plate 6.

[0033] To prevent injury, the main body shell 1 is provided with a protective plate 20 that shields the main gear 12 and the auxiliary gear 7.

[0034] To facilitate movement, the lower end of the main body shell 1 is equipped with multiple casters.

[0035] When using this utility model, firstly, the chicken bones to be crushed are poured into the feed hopper 2. Due to the obstruction of the baffle plate 6 and the elasticity of the spring 17, the chicken bones accumulate on the baffle plate 6 and cannot fall between the crushing wheels 4. Then, the motor 13 is started. The motor 13 drives the front rotating shaft 3 to rotate, which drives the two crushing wheels 4 to rotate through the main gear 12. At the same time, it drives the turntable 10 and the protrusion 11 on it to rotate. After rotating a certain angle, the protrusion 11 contacts the lower end of the moving rod 8 and presses the moving rod 8 upward.

[0036] The moving rod 8 drives the two racks 9 to move upward. The two racks 9 move upward and contact the corresponding secondary gear 7, which drives the secondary gear 7 to rotate. The secondary gear 7 drives the rotating column 5 to drive the baffle 6 to rotate. The two baffles 6 swing downward to release the chicken bones. The chicken bones piled on them fall onto the two guide plates 19 due to gravity and slide between the two crushing wheels 4 to crush the chicken bones. The crushed chicken bones fall into the collection box 18. After rotating a certain angle, the cam disengages from the moving rod 8. At this time, the restoring force of the spring 17 drives the moving rod 8 to move downward. The moving rod 8 drives the racks 9 to move downward, which in turn drives the two baffles 6 to swing upward. After swinging upward a certain angle, they return to the initial position and resume the blocking to prevent the chicken bones from falling continuously.

[0037] The motor 13 rotates continuously, which in turn drives the turntable 10 and its cam to rotate continuously, repeatedly contacting the moving rod 8 and causing the baffle plate 6 to swing down and release the baffle. This causes the chicken bones in the feed hopper 2 to fall intermittently, avoiding the accumulation of chicken bones. Then the collection box 18 is pulled out and the chicken bone powder is collected.

[0038] Compared with the prior art, the beneficial effects of this utility model are: the crushing wheel, motor, baffle plate, etc. provided can crush chicken bones, and the raw chicken bones in the feed hopper can be dropped intermittently during the crushing process. Compared with the traditional continuous feeding, it avoids the accumulation of chicken bones and the bridging and blockage at the feed hopper outlet. This structure is simple, novel in design, easy to use, and highly practical.

[0039] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
