Background Art

[0002] The so-called geographical feed resources refer to by-products (waste materials) of grain processing plants, such as soybean meal, corn flour, bran, bean skin, peanut skin, etc. The original process of these materials is to use positive pressure conveying, convey them to the water mixer on the spreader, add water, inoculate, and then spread the fermented materials on the fermentation bed by the spreader for fermentation. Since most of the raw materials are carbohydrates, there is a risk of fire or explosion when using air flow conveying. As the country attaches great importance to production safety, some companies require that materials cannot be conveyed by positive pressure.

[0003] In view of the fact that the material cannot be transported by pneumatic conveying, and the fermentation material entering the fermentation bed needs to be continuously distributed to a rectangular fermentation bed, the distribution machine on the fermentation bed needs to be equipped with a continuous feeding and a movable feeding port in the length direction of the fermentation bed.

They are only for the convenience of describing the utility model and simplifying the description, and do not mean that the device must have a specific direction.

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below with reference to specific figures. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0024] like Figures 1 to 4 As shown, the rectangular fermentation bed solid dry material conveying and distributing system of the utility model comprises a plurality of rectangular fermentation beds 13 arranged side by side, two adjacent rectangular fermentation beds 13 constitute a group, and four rectangular fermentation beds 13 constitute two groups as an example. A common and fixed transverse scraper conveyor 1 is provided above each rectangular fermentation bed 13, and the transverse scraper conveyor 1 spans above each rectangular fermentation bed 13 along the width direction. Inlet and outlet channels are provided between the rectangular fermentation beds 13 in the same group, and artificial walkways 14 are provided above each inlet and outlet channel, respectively, and two longitudinally movable scraper conveyors 3 that move in translation along the length direction of the fermentation bed are symmetrically provided on both sides of the artificial walkway 14.

[0025] The upper ports of each longitudinally movable scraper conveyor 3 are covered with a foldable or unfoldable soft cover 4 to prevent dust from being blown out. Fixed chutes 2 are connected below the corresponding discharge ports of the transverse scraper conveyors 1, and the lower ports of the fixed chutes 2 are inserted into the upper ports of the corresponding longitudinally movable scraper conveyors 3 through the gaps of the soft covers 4.

[0026] Each longitudinally movable scraper conveyor 3 is provided with a discharge port at both ends and is connected to a movable chute 5. The two discharge ports are respectively responsible for distributing the material in the front and rear halves of the rectangular fermentation bed 13. The longitudinally movable scraper conveyor 3 only needs to move half the length of the rectangular fermentation bed 13.

[0027] When the longitudinally movable scraper conveyor 3 moves along the length direction of the rectangular fermentation bed 13, the fixed chute 2 remains stationary, the soft cover 4 on one side of the fixed chute 2 is folded, and the soft cover 4 on the other side is unfolded, always maintaining a good sealing state.

[0028] The discharge port of each longitudinally movable scraper conveyor 3 is respectively connected to a movable chute 5. The feeding mechanism of the same group of rectangular fermentation beds 13 is arranged in a mirror image. The upper port of each rectangular fermentation bed 13 is respectively provided with a water-adding inoculation distribution machine 6 for distributing the material horizontally along the entire length of the fermentation bed. The feed hopper of the water-adding inoculation distribution machine 6 of the same group is respectively located on one side above the material inlet and outlet channels and is respectively connected to a dust hood 7. The lower ports of the movable chute 5 are respectively inserted into the corresponding dust hoods 7.

[0029] The water-adding inoculation spreading machine 6 is provided with an upper and lower layer, the upper layer is a water-adding mixer for mixing materials with hot water, and the lower layer is an inoculation mixer for mixing with bacterial strains. The materials first enter the water-adding mixer of the upper layer to be evenly mixed with hot water, and then enter the inoculation mixer of the lower layer to be evenly mixed with bacterial liquid, and then spread along the width direction of the rectangular fermentation bed 13; after the same cross-section is spread, it is translated along the length direction of the rectangular fermentation bed 13 to complete the spreading of the entire area.

[0030] The longitudinally movable scraper conveyor 3 is parallel to the length direction of the rectangular fermentation bed 13, and moves synchronously with the water-adding inoculation distributor 6. The discharge port of the longitudinally movable scraper conveyor 3 always moves synchronously with the hopper on the water-adding mixer on the upper layer of the water-adding inoculation distributor 6. The generated dust is sucked away by the dust hood 7. The horizontal scraper conveyor 1 and the discharge end of the longitudinally movable scraper conveyor 3 are equipped with ventilation and dust removal systems, which can prevent the material from leaking and causing dust to be blown out during the conveying process.

[0031] After fermentation is completed, the material is discharged by the discharge machine 11 along the width direction of the rectangular fermentation bed 13, and the material discharged by the discharge machine 11 is conveyed by the discharge belt conveyor 12 toward the main belt conveyor.

[0032] A parking area 8 for parking the water-adding inoculation distributor 6 is provided on the outside of one end of each rectangular fermentation bed 13, and a parking area track 8a is provided on the top of the parking area 8 for the water-adding inoculation distributor 6 to travel and support. A common transverse ferry channel 9 is provided between the parking area 8 and the end of the rectangular fermentation bed 13, and a common ferry vehicle 10 is provided on the transverse ferry channel 9, and a longitudinal ferry track 10a is provided on the top of the ferry vehicle 10 for the water-adding inoculation distributor 6 to travel to the parking area 8.

[0033] Four rectangular fermentation beds 13 can share two water-added inoculation spreading machines 6, one for spreading on the left side and the other for spreading on the right side; they can share two discharging machines 11, one for discharging on the left side and the other for discharging on the right side. On the one hand, the investment in spreading machines and discharging machines can be saved. On the other hand, when a rectangular fermentation bed 13 is spreading, the discharging machine 11 can be parked in the parking area 8; when discharging, the water-added inoculation spreading machine 6 can be parked in the parking area 8 to avoid mutual interference. When ferrying, the ferry car 10 moves horizontally along the horizontal ferry channel 9 to the end of the corresponding rectangular fermentation bed 13, so that the longitudinal ferry track 10a is aligned and connected with the parking area track 8a, and the water-added inoculation spreading machine 6 and the discharging machine 11 move along the longitudinal ferry track 10a until they reach the parking area track 8a; the ferry car 10 can also carry the water-added inoculation spreading machine 6 and the discharging machine 11 and move horizontally to another parking area 8.
