Description

Technical Field

[0001] The invention relates to the technical field of solid-state biological fermentation equipment, and in particular to a solid-state fermentation unloading device. Background Art

[0002] Solid-state fermented feed is a high-value-added biological feed product obtained by processing agricultural and sideline products and other feed raw materials using biotechnology. In the production of solid-state fermented feed, the fermentation raw materials used are widely available and inexpensive, such as various low-value agricultural and sideline products such as cakes, bran, and dregs. The nutritional level of the fermented materials is significantly improved after microbial fermentation. Beneficial microorganisms secrete rich beneficial metabolites into the materials during the fermentation process. The original anti-nutritional factors in the raw materials are eliminated to a large extent, the palatability of the materials is improved, and the feed digestibility is improved.

[0003] At present, the special production equipment for solid-state fermentation is still relatively backward. The fermentation process of solid-state fermentation feed is mostly produced by pile fermentation. The materials to be fermented after inoculation with microbial liquid are piled on the ground or in masonry fermentation tanks. A large number of workers and auxiliary equipment are required to operate and process in the fermentation area, such as transferring the materials to be fermented into the fermentation area, performing pile sorting operations in the fermentation area, and transferring the fermented materials out of the fermentation area.

[0004] Since fermented feed has a high moisture content and a certain viscosity, workers and auxiliary equipment are prone to carry fermented feed everywhere when operating in the fermentation area. The sanitary conditions in the production area are poor and difficult to control, which is very unfavorable to the quality control of fermented feed. At the same time, the manual operation workload is very large, the production efficiency is slow, and it is not conducive to efficient industrial production.

[0005] Box-type solid-state fermentation technology can solve the above-mentioned technical problems. The fermentation process requires little manual labor, has a high degree of mechanization, has good sanitary conditions in the production area and is easy to control, and can achieve large-scale industrial rapid production.

[0006] The process of box-type solid-state fermentation is as follows: Fig.19As shown, the fermentation box 16 is a box body with both ends connected. The fermentation box 16 is set on the frame base. A plurality of movable wheels 19 are set below the frame base for the fermentation box 16 to move and transfer. On the two opposite sides of the lower part of the fermentation box 16, there are insertion holes for the movable bottom plate 17 to move and insert horizontally between the fermentation box 16 and the frame base. The two movable bottom plates 17 are respectively inserted into the corresponding insertion holes from the two opposite sides of the fermentation box 16. The sides of the two movable bottom plates 17 are supported by the frame base. The movable bottom plate 17 can be a bottom plate with reinforced steel beams. After the two movable bottom plates 17 are respectively inserted into the corresponding insertion holes, the lower end of the fermentation box 16 will be sealed by the two movable bottom plates 17, that is, at this time, the two movable bottom plates 17 become the bottom of the fermentation box 16. The middle part of the outer side of the two movable bottom plates 17 is provided with a pull handle 18 to realize the translation and insertion of the movable bottom plate 17.

[0007] The material to be fermented after inoculation with microbial liquid is added into the fermentation box 16, and the fermentation box 16 and two movable bottom plates 17 contain the added material. The fermentation box 16 containing the material to be fermented is moved and transferred into the fermentation area. After the material contained in the fermentation box 16 is fermented in the fermentation area, the fermentation box 16 is moved from the fermentation area to the discharge pit 21. The fermentation box 16 is placed on the discharge pit 21. At this time, the handles 18 on the movable bottom plate 17 are pulled outward respectively, and the handles 18 will drive the corresponding movable bottom plate 17 to move outward in the insertion hole. At this time, the bottom of the fermentation box 16 is opened, and the fermented material contained in the fermentation box 16 falls into the discharge pit 21 below. The material received in the discharge pit 21 can be transported to the feed port of the next processing equipment through the conveyor arranged at the bottom of the discharge pit 21.

[0008] After all the materials in the fermentation box 16 fall into the discharge pit 21, the two movable bottom plates 17 are moved toward each other in the insertion and extraction holes by pushing the pull handle 18 until the lower end discharge port of the fermentation box 16 is sealed by the two movable bottom plates 17. At this time, the fermentation box has completed unloading and can continue to be recycled.

[0009] However, corresponding to the above-mentioned box-type solid-state fermentation process, there is no mechanized, efficient and dedicated unloading device matched with the fermentation box 16 to realize the mechanized pushing and pulling of the movable bottom plate 17 for unloading.

[0010] In order to achieve the purpose of mechanized and efficient unloading operation of the fermentation box 16 in the above-mentioned box-type solid-state fermentation process, it is necessary to design a special unloading device. Summary of the invention

[0049] Preferably, the number of the guide rails 5 is two, and the two guide rails 5 are arranged in parallel on both sides of the screw rod 2; the number of the sliders 8 is two, and the two sliders 8 are arranged at the lower part of the push-pull block 4; the two sliders 8 are respectively slidably mounted on the two guide rails 5.

[0050] Preferably, both ends of the push plate 10 are bent toward the left side of the frame 1 on the upper surface of the push-pull block 4 .

[0051] Preferably, it also includes a telescopic top fixing device 7, the number of which is two, and the two telescopic top fixing devices 7 are respectively arranged on the side where the two auxiliary frames 6 are close to each other, and the movable ends 22 of the two telescopic top fixing devices 7 are both horizontally facing the right side of the frame 1, and the two telescopic top fixing devices 7 are arranged on the right side of the frame 1.

[0052] Preferably, it further includes a roller 15 , and a plurality of parallel rollers 15 are arranged in the two guide support seats 14 along the axial direction of the screw rod 2 .

[0053] Preferably, it also includes a second travel switch 12, which is arranged on the push-pull block 4, and the action part of the second travel switch 12 is arranged on the groove formed by the pull plate 9 and the push plate 10 on the upper surface of the push-pull block 4, and the second travel switch 12 is electrically connected to the sound and light alarm.

[0054] Preferably, it also includes a first travel switch 11 and a third travel switch 13, the first travel switch 11 and the third travel switch 13 are both arranged on the push-pull block 4, the action parts of the first travel switch 11 and the third travel switch 13 are both arranged on the grooves formed by the pull plate 9 and the push plate 10 on the upper surface of the push-pull block 4, the first travel switch 11 and the third travel switch 13 are located on both sides of the second travel switch 12, and the first travel switch 11 and the third travel switch 13 are both electrically connected to the sound and light alarm.

[0055] Preferably, it also includes a PLC automatic control module and a positioning signal sensor. The positioning signal sensor is arranged on the push-pull block 4. The positioning signal sensor and the drive motor 3 are electrically connected to the PLC automatic control module.

[0056] Preferably, the telescopic fixing device 7 is any one of an electric telescopic rod, a cylinder, and a hydraulic cylinder.

[0057] The method of using the present invention is as follows: two solid-state fermentation unloading devices of the present invention are symmetrically arranged facing each other on both sides of the unloading pit 21 , so that one side of the pull plate 9 in the two solid-state fermentation unloading devices is close to the unloading pit 21 .

[0058] Start the driving motors 3 in the two solid-state fermentation unloading devices, and the screw rods 2 in the two solid-state fermentation unloading devices rotate. Since the push-pull block 4 is threadedly connected to the screw rod 2, if a screw nut seat is installed in the push-pull block 4, each push-pull block 4 starts to move on the screw rod 2 under the action of the corresponding screw rod 2, so that the two push-pull blocks 4 move in a direction away from the driving motor 3 (i.e., the outer end of the screw rod 2) and close to the edge of the unloading pit 21. When each push-pull block 4 moves on the screw rod 2, the slider 8 moves synchronously on the guide rail 5, and the guide rail 5 makes the movement of each push-pull block 4 stable. When the two push-pull blocks 4 reach the outer end of the screw rod 2, the driving motor 3 stops running, and the two push-pull blocks 4 stop moving. At this time, the distance between the two pull plates 9 on the two push-pull blocks 4 is smaller than the inner end surface distance between the pull handles 18 on both sides of the fermentation box 16, and the distance between the two push plates 10 is larger than the outer end surface distance between the pull handles 18 on both sides of the fermentation box 16, that is, the pull handles 18 on both sides of the fermentation box 16 can smoothly enter the corresponding grooves between the pull plates 9 and the push plates 10.

[0059] After the fermentation of the materials in the fermentation box 16 is completed, the fermentation box 16 is moved close to the unloading pit 21 by the moving wheels 19 at the bottom of the fermentation box 16. Before the fermentation box enters between the two solid-state fermentation unloading devices, the handles 18 on both sides of the fermentation box 16 are respectively directed toward the two solid-state fermentation unloading devices. In the process of the fermentation box 16 entering between the two solid-state fermentation unloading devices, the handles 18 on both sides of the fermentation box 16 will respectively enter the grooves formed on the upper surface of the push-pull block 4 by the corresponding pull plates 9 and push plates 10.

[0060] Both ends of the push plate 10 are bent toward the left side of the frame 1 on the upper surface of the push-pull block 4, so that the openings at both ends of the pull plate 9 and the push plate 10 are diffused trumpet-shaped, which is more conducive to the pull handle 18 to smoothly enter the groove formed on the upper surface of the pull plate 9 and the push plate 10 on the push-pull block 4.

[0061] If only the second stroke switch 12 is set on the push-pull block 4, the second stroke switch 12 is electrically connected to the sound and light alarm. When the handles 18 on both sides of the fermentation box 16 respectively enter the corresponding grooves formed by the pull plates 9 and the push plates 10 on the upper surface of the push-pull block 4, the handles 18 will touch the action part of the second stroke switch 12. After detecting the action, the second stroke switch 12 can send a signal to the sound and light alarm. The sound and light alarm prompts that the handle 18 of the fermentation box 16 is in place. At this time, the movement of the fermentation box 16 can be stopped, and the drive motor 3 can be started. The rotating screw 2 drives the pull plate 9 to move in the direction of the drive motor 3. The pull plate 9 hooks the handle 18 and pulls the movable bottom plate 17 out of the extraction and insertion hole of the fermentation box 16 to achieve smooth unloading.

[0062] If the push-pull block 4 is provided with the first travel switch 11, the second travel switch 12, and the third travel switch 13 as described above, the first travel switch 11, the second travel switch 12, and the third travel switch 13 are all electrically connected to the sound and light alarm.

[0063] When the pull handle 18 enters the groove formed on the upper surface of the push-pull block 4 by the pull plate 9 and the push plate 10, it will first touch the travel switch (the first travel switch 11 or the third travel switch 13) on the outside of the push-pull block 4. After detecting the action, the travel switch (the first travel switch 11 or the third travel switch 13) on the outside of the push-pull block 4 can send a signal to the sound and light alarm. The sound and light alarm prompts to slowly move the fermentation box 16. When the pull handle 18 moves to between the first travel switch 11 and the third travel switch 13, the pull handle 18 does not touch the action part of the first travel switch 11 and the third travel switch 13, but because the second travel switch When the switch 12 is in a position between the first stroke switch 11 and the third stroke switch 13, the handle 18 will inevitably touch the second stroke switch 12, that is, when the second stroke switch 12 detects an action, neither the first stroke switch 11 nor the third stroke switch 13 detects an action. The state at this time indicates that the handle 18 of the fermentation box 16 is in the middle of the groove formed by the pull plate 9 and the push plate 10 on the upper surface of the push-pull block 4 of the solid-state fermentation unloading device. At this time, the handle 18 of the fermentation box 16 and the pull plates 9 on both sides are subjected to the most balanced and stable force, and it is easier to pull the handle 18 by the pull plate 9 to pull the movable bottom plate 17 out of the extraction hole of the fermentation box 16 to achieve smooth unloading.

[0064] Alternatively, the first travel switch 11, the second travel switch 12, and the third travel switch 13 are connected to the PLC control system of the mobile drive device of the fermentation box 16, and the movement speed and parking position of the fermentation box 16 are automatically controlled through the action detection of the first travel switch 11, the second travel switch 12, and the third travel switch 13, which is more accurate, convenient, and quick.

[0065] Before the pull plate 9 pulls the handle 18 to pull the movable bottom plate 17 out of the insertion and withdrawal hole of the fermentation box 16, the telescopic top fixing device 7 is started, and the movable end 22 of the telescopic top fixing device 7 approaches the fermentation box 16 until the movable end 22 of the telescopic top fixing device 7 fixes the fermentation box 16, that is, the telescopic top fixing devices 7 on both sides of the fermentation box 16 stabilize the fermentation box 16, and when the movable bottom plate 17 is pulled out of the insertion and withdrawal hole of the fermentation box 16, the fermentation box 16 will not shake.

[0066] When the movable bottom plate 17 is pulled out from the insertion hole of the fermentation box 16, the movable bottom plate 17 will move into the guide support seat 14, and the two guide support seats 14 on both sides of the movable bottom plate 17 support and guide the movable bottom plate 17. With the help of multiple rollers 15 arranged in the guide support seat 14, the movable bottom plate 17 can move on the rollers 15, reducing the resistance of the movable bottom plate 17 to movement.

[0067] The solid-state fermentation unloading device of the present invention can also be provided with a PLC automatic control module and a positioning signal sensor, and the positioning signal sensor is provided on the push-pull block 4, and the positioning signal sensor and the drive motor 3 are electrically connected to the PLC automatic control module. The positioning signal sensor and the PLC automatic control module are used to precisely control the drive motor 3, so that the push-pull block 4 can stop automatically at the set position.

[0068] The movable bottom plate 17 of the fermentation box 16 is pulled out by the push-pull blocks 4 of the two solid-state fermentation unloading devices of the present invention to complete the unloading. The materials in the fermentation box 16 fall directly into the unloading pit 21 due to gravity. After the unloading is completed, the drive motor 3 is controlled to move in the reverse direction, and the screw rod 2 causes the push plate 10 on the push-pull block 4 to push the movable bottom plate 17 into the insertion and extraction hole of the fermentation box 16, and finally the two movable bottom plates 17 of the fermentation box 16 are closed, and the movable ends 22 of the two telescopic top fixing devices 7 are retracted. At this time, the fermentation box 16 can be moved away from between the two solid-state fermentation unloading devices.

[0069] The telescopic fixing device 7 can be an electric telescopic rod or a cylinder or a hydraulic cylinder.

[0070] A track 20 can also be set on the edge of the unloading pit 21. The moving wheel 19 uses a cam. The moving wheel 19 of the fermentation box 16 can be moved between the two solid-state fermentation unloading devices through the track 20. The track 20 can play a guiding role and also play a role in stabilizing the fermentation box 16.
