Description

Technical Field

[0001] The utility model relates to the technical field of scraping devices, and more specifically to a scraping device for a fermentation tank. Background Art

[0002] Bio-organic fertilizer composting fermentation is the use of animal and plant remains, domestic waste, crop straw, excrement, etc. containing fertilizer ingredients, mixed with soil and minerals, and then fermented and decomposed by microorganisms under high temperature and humidity conditions to form a bio-organic fertilizer.

[0003] After the composting fermentation is completed, the fertilizer needs to be transported to the outside of the fermentation tank. In some fermentation plants, personnel usually use a sewage pump to extract the fertilizer in the fermentation tank to the outside. Since the fermentation tank ferments the fertilizer in a composting manner, during the composting fermentation process, the fertilizer in the upper layer of the fermentation tank is subjected to less pressure, is not easy to agglomerate, and has a loose shape. Therefore, it is easy to be extracted. However, the fertilizer in the middle and lower layers of the fermentation tank is easy to agglomerate during the long-term composting fermentation process, and it is difficult to directly extract it with a sewage pump. Manual intervention is required to break up the fertilizer and shovel it to the vicinity of the feed pipe of the sewage pump. The closer to the lower layer, the more solid the fertilizer clumps will be, the greater the workload of the personnel, and the slower the work efficiency will be. Therefore, the utility model provides a shoveling device for a fermentation tank. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a scraping device for a fermentation tank, which solves the problem in the prior art that during the composting fermentation process, the fertilizer in the upper layer of the fermentation tank is subjected to less pressure, is not easy to clump, and has a loose shape. Therefore, it is easy to be extracted, but the fertilizer in the middle and lower layers of the fermentation tank is easy to clump during the long-term composting fermentation process, and it is difficult to directly extract it with a sewage pump. Manual intervention is required to break up the fertilizer and scrape it to the vicinity of the feed pipe of the sewage pump. The closer to the lower layer, the more solid the fertilizer clumps will be, the greater the workload of personnel, and the lower the work efficiency will be.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A material scraping device for a fermentation tank, comprising a fermentation tank body and a shell, the upper end of the fermentation tank body is fixedly connected to the shell, the upper end of the shell is provided with a strip-shaped through hole, a threaded screw is rotatably connected in the shell, a servo motor is fixedly connected to one side of the shell, the output end of the servo motor is connected to the threaded screw, the outer circumferential surface of the threaded screw is threadedly connected to a screw rod set, the outer circumferential surface of the screw rod set is fixedly connected to a connecting block, one side of the connecting block is fixedly connected to a connecting rod, the upper end of the connecting rod is fixedly connected to an electric telescopic rod, the output end of the electric telescopic rod is fixedly connected to a connecting plate, and the lower end of the connecting plate is fixedly connected to a material scraping plate and a vibration mechanism;

[0009] A main controller is fixedly connected to one side of the shell.

[0010] Furthermore, the vibration mechanism includes a connecting frame, a connecting block, a connecting column, a spring, a loosening rod and a vibration assembly. A connecting block is arranged in the connecting frame, and slots are provided on both sides of the connecting block. Connecting columns are fixedly connected on both sides of the connecting frame, and one end of the connecting column extends into the slot. Springs are also fixedly connected on both sides of the connecting frame. The springs are sleeved on the outer circumferential surface of the connecting column and fixed to the connecting block.

[0013] Furthermore, one end of the connecting rod is fixedly connected to a supporting rod, and the lower end of the supporting rod is rotatably connected to a roller.

[0014] Beneficial Effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) In this scheme, the main controller controls the servo motor, the electric telescopic rod and the vibration mechanism to start. When the fertilizer in the fermentation tank body is extracted to the middle, the electric telescopic rod is started first. The electric telescopic rod cooperates with the connecting plate to drive the scraping plate and the vibration mechanism to embed into the fertilizer in the middle. Then the servo motor is started again. The servo motor drives the threaded screw to rotate. Since the connecting block is connected to the screw rod kit and the connecting block is limited by the strip opening, the rotating threaded screw can drive the screw rod kit to move horizontally. The horizontally displaced screw rod kit cooperates with the connecting block and the connecting rod to drive the scraping plate to move. During the movement of the scraping plate, the fertilizer in the fermentation tank body can be scraped to one side. Since the fertilizer clumps in the middle are not particularly compact, the fertilizer will be automatically broken up due to deformation when being scraped, and no manual processing is required, which greatly reduces the labor burden of personnel and improves work efficiency.

[0017] (2) In this scheme, when the fertilizer in the fermentation tank body is extracted to the lower layer, the vibration component is started. Since the connecting block is elastically connected to the connecting frame through the connecting column and the spring, when the vibration component is running, the vibration component can drive the connecting block to vibrate in the horizontal direction. When vibrating, the connecting block cooperates with the loosening rod to first break up the relatively solid fertilizer in the lower layer, and then cooperates with the scraping plate to scrape the fertilizer to one side, so as to avoid the problem that the servo motor torque is insufficient, resulting in the inability to scrape the fertilizer in the lower layer.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Example

[0026] like Figure 1-4 As shown, a material scraping device for a fermentation tank comprises a fermentation tank body 1 and a shell 2, the upper end of the fermentation tank body 1 is fixedly connected with the shell 2, the upper end of the shell 2 is provided with a strip-shaped through-hole 21, a threaded screw 3 is rotatably connected in the shell 2, one side of the shell 2 is fixedly connected with a servo motor 4, the output end of the servo motor 4 is connected with the threaded screw 3, the outer circumferential surface of the threaded screw 3 is threadedly connected with a screw set 5, the outer circumferential surface of the screw set 5 is fixedly connected with a connecting block 6, one side of the connecting block 6 is fixedly connected with a connecting rod 7, the upper end of the connecting rod 7 is fixedly connected with an electric telescopic rod 8, the output end of the electric telescopic rod 8 is fixedly connected with a connecting plate 81, and the lower end of the connecting plate 81 is fixedly connected with a material scraping plate 82 and a vibration mechanism 9;

[0027] A main controller 22 is fixedly connected to one side of the housing 2 .

[0028] When in use, the main controller 22 controls the servo motor 4, the electric telescopic rod 8 and the vibration mechanism 9 to start. When the fertilizer in the fermentation tank body 1 is extracted to the middle, the electric telescopic rod 8 is started first. The electric telescopic rod 8 cooperates with the connecting plate 81 to drive the scraping plate 82 and the vibration mechanism 9 to embed into the fertilizer in the middle, and then the servo motor 4 is started. The servo motor 4 will drive the threaded screw 3 to rotate. Since the connecting block 6 is connected to the screw rod kit 5, and the connecting block 6 is limited by the strip opening 21, the rotating threaded screw 3 can drive the screw rod kit 5 to move horizontally. The horizontally displaced screw rod kit 5 cooperates with the connecting block 6 and the connecting rod 7 to drive the scraping plate 82 to move. During the movement, the scraping plate 82 can scrape the fertilizer in the fermentation tank body 1 to one side. Since the fertilizer clumps in the middle are not particularly compact, the fertilizer will be automatically broken up due to deformation when being scraped, and no manual processing is required, which greatly reduces the labor burden of personnel and improves work efficiency.

[0029] like Figure 1-4As shown, the vibration mechanism 9 includes a connecting frame 91, a connecting block 92, a connecting column 93, a spring 94, a loosening rod 95 and a vibration component 96. A connecting block 92 is arranged in the connecting frame 91, and slots 921 are provided on both sides of the connecting block 92. Connecting columns 93 are fixedly connected to both sides of the connecting frame 91, and one end of the connecting column 93 extends into the slot 921. Springs 94 are also fixedly connected to both sides of the connecting frame 91. The springs 94 are sleeved on the outer circumferential surface of the connecting column 93 and fixed to the connecting block 92. The loosening rod 95 is fixedly connected to the lower end of the connecting block 92, and the vibration component 96 is fixedly connected to one side of the connecting block 92.

[0030] During use, when the fertilizer in the fermentation tank body 1 is extracted to the lower layer, the vibration component 96 is started. Since the connecting block 92 is elastically connected with the connecting frame 91 through the connecting column 93 and the spring 94, when the vibration component 96 is running, the vibration component 96 can drive the connecting block 92 to vibrate in the horizontal direction. When vibrating, the connecting block 92 cooperates with the loosening rod 95 to first break up the relatively solid fertilizer in the lower layer, and then cooperates with the scraping plate 82 to scrape the fertilizer to one side, so as to avoid the servo motor 4 having insufficient torque, which makes it impossible to scrape the fertilizer in the lower layer.

[0031] like Figure 2 As shown, a notch 911 is formed on one side of the connection frame 91 , and the notch 911 corresponds to the vibration component 96 .

[0032] During use, when the vibration component 96 drives the connecting block 92 to vibrate horizontally, the vibration component 96 will not collide with the connecting frame 91 .

[0033] like Figure 2 and 4 As shown, the vibration assembly 96 includes a housing 961, a small motor 962 and an eccentric wheel 963. The small motor 962 is fixedly connected to the inner bottom end of the housing 961, and the eccentric wheel 963 is fixedly connected to the output end of the small motor 962.

[0034] When in use, since the eccentric wheel 963 is installed at the upper output end of the small motor 962, when the small motor 962 drives the eccentric wheel 963 to rotate, vibration in the horizontal direction can be generated.

[0035] like Figure 1 As shown, one end of the connecting rod 7 is fixedly connected to a supporting rod 71 , and the lower end of the supporting rod 71 is rotatably connected to a roller 72 .

[0036] When in use, the support rod 71 cooperates with the roller 72 to support one end of the connecting rod 7 to improve the stability of the connecting rod 7.

[0037] In summary, the specific working process of this scheme is as follows: the main controller 22 controls the servo motor 4, the electric telescopic rod 8 and the vibration mechanism 9 to start. When the fertilizer in the fermentation tank body 1 is extracted to the middle, the electric telescopic rod 8 is started first. The electric telescopic rod 8 cooperates with the connecting plate 81 to drive the scraping plate 82 and the vibration mechanism 9 to embed into the fertilizer in the middle, and then the servo motor 4 is started again. The servo motor 4 will drive the threaded screw 3 to rotate. Since the connecting block 6 is connected to the screw rod set 5, and the connecting block 6 is limited by the strip-shaped opening 21, the rotating threaded screw 3 can drive the screw rod set 5 to move horizontally. The horizontally displaced screw rod set 5 cooperates with the connecting block 6 and the connecting rod 7 to drive the scraping plate 82 to move. During the movement, the scraping plate 82 can scrape the fertilizer in the fermentation tank body 1 to one side. Since the fertilizer agglomerates in the middle are not particularly compact, the fertilizer will be automatically broken up due to deformation when being scraped, and no manual processing is required, which greatly reduces the labor burden of the personnel and improves the work efficiency.

[0038] Among them, when the fertilizer in the fermentation tank body 1 is extracted to the lower layer, the vibration component 96 is started. Since the connecting block 92 is elastically connected with the connecting frame 91 through the connecting column 93 and the spring 94, when the vibration component 96 is running, the vibration component 96 can drive the connecting block 92 to vibrate in the horizontal direction. When vibrating, the connecting block 92 cooperates with the loosening rod 95 to first break up the relatively solid fertilizer in the lower layer, and then cooperates with the scraping plate 82 to scrape the fertilizer to one side, so as to avoid the problem that the servo motor 4 has insufficient torque and cannot scrape the fertilizer in the lower layer.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
