DETAILED DESCRIPTION

[0022] For example, Figs. 1-3The utility model relates to a feed anti-caking turnover device for solid state fermentation, which comprises a vehicle body 1, a lifting belt 3 arranged at the front end of the vehicle body 1, a spiral feeder 5 arranged at the top of the vehicle body 1, and a broken material hopper 2 arranged at the rear end of the vehicle body 1.

[0023] The output end of the lifting belt 3 is located above the feeding pipe 501 at one end of the spiral feeder 5, and the discharging pipe 502 at the other end of the spiral feeder 5 is located above the broken material hopper 2.

[0024] The broken material hopper 2 is provided with a sieve cylinder 6, and the inside of the sieve cylinder 6 is provided with a spiral blade 7 fixedly arranged in the broken material hopper 2. The broken material hopper 2 is also provided with a broken tooth cylinder 8 tangentially arranged on the outer wall of the sieve cylinder 6.

[0025] In the preferred embodiment, the lifting belt 3 is provided with a scraping plate 4 on the belt surface.

[0026] In the preferred embodiment, one end of the sieve cylinder 6 is closed by a circular plate 601, and the other end is provided with an annular frame plate. The circular plate 601 and the annular frame plate are embedded on the inner wall of the broken material hopper 2. The circular plate 601 is provided with a center column 602 extending out of the broken material hopper 2. One end of the central axis of the broken tooth cylinder 8 also extends out of the broken material hopper 2. A driven gear 13 is arranged on the center column 602 outside the broken material hopper 2. A driving gear 14 is arranged on the central axis of the broken tooth cylinder 8 outside the broken material hopper 2. The driven gear 13 and the driving gear 14 are in meshing engagement.

[0027] The central axis of the broken tooth cylinder 8 is driven by a motor 15 arranged on the outer wall of the broken material hopper 2.

[0028] In the preferred embodiment, a fine material outlet 12 is arranged on the side wall of the broken material hopper 2 corresponding to the open end of the sieve cylinder 6.

[0029] In the preferred embodiment, an extension plate 9 is arranged on the top surface of the broken material hopper 2 near the side of the vehicle body 1, extending downwardly and obliquely. An active baffle 10 is mounted on the end of the extension plate 9 through a pin shaft and a torsion spring. The end of the active baffle 10 is in contact with the outer wall of the sieve cylinder 6.

[0030] In the preferred embodiment, a fixed baffle 11 is arranged in the broken material hopper 2 near the bottom. The fixed baffle 11 is located on the tangent position of the outer wall of the sieve cylinder 6.

[0031] In the preferred embodiment, a cab 16 is arranged on one side of the vehicle body 1. The cab 16 and the fine material outlet 12 are arranged on the same side of the vehicle body 1.

[0032] The feed anti-caking turnover device for solid state fermentation disclosed in the utility model can perform turnover operation of fermented feed.

[0033] The vehicle body moves forward, and the feed on the ground is first lifted by the front end of the lifting belt 3. The lifting belt 3 is inclinedly arranged so that the material can move upward along the belt slope. The lifting belt is provided with material scraping plates 4, which can increase the grabbing force of the material, prevent the material from slipping during lifting, and help uniformly deliver the material to the feed inlet pipe 501 of the screw feeder 5.

[0034] When the material reaches the screw feeder 5, the screw shaft rotates to push the material forward. The screw feeder 5 not only transfers the material from the lifting belt to the crushing hopper 2, but also plays a certain stirring role to preliminarily mix and crush the material.

[0035] After the material enters the crushing hopper 2, it first falls on the surface of the screen cylinder 6 (the movable baffle 10 on one side effectively prevents the material from falling through the gap). The fine part falls into the screen cylinder 6, which is provided with spiral blades 7 inside. With the rotation of the screen cylinder 6, the spiral blades 7 push the material forward and discharge it from the fine material outlet 12 to one side of the vehicle body 1. The coarse material and lumps are located on the surface of the screen cylinder 6 and reach the gap between the screen cylinder 6 and the crushing tooth cylinder 8 with the rotation of the screen cylinder 6.

[0036] The crushing tooth cylinder 8 is arranged close to the outer side of the screen cylinder 6 and is composed of a series of hard alloy blades. When larger particles or lumps in the material contact the crushing tooth cylinder 8, these large particles are broken and pressed into smaller particles due to the high-speed rotation of the crushing tooth cylinder 8. The central shaft of the crushing tooth cylinder 8 is driven by the motor 15 and works in linkage with the screen cylinder 6 through a gear set (driven gear 13 and driving gear 14), ensuring synchronous and reverse rotation of the two.

[0037] In order to prevent the material from adhering to the outer wall of the screen cylinder 6 and affecting the working efficiency, a fixed scraper 11 is arranged at the tangent position of the outer wall of the screen cylinder 6. The fixed scraper 11 can help clean the residual material on the outer wall of the screen cylinder, maintaining the screening efficiency.

[0038] The operation of the entire device can be completed in the cab 16. The operator can adjust the speed of the lifting belt 3, the rotation speed of the screw feeder 5, and the working state of the crushing tooth cylinder 8 through the control system to adapt to different types of feed raw materials. In addition, the cab is also provided with an observation window for monitoring the entire operation process.

[0039] Through the above operation, the solid-state fermented feed can realize turning and uniform distribution, solve the problems of caking and uneven accumulation of feed, and effectively improve the fermentation efficiency and quality of the feed.
