Description

Technical Field

[0001] This application belongs to the field of soybean paste industrial production technology, and in particular relates to a scraping structure. Background Technology

[0002] In the production process of broad bean paste, broad beans that have completed koji making and salted chili flakes are mixed together and then transferred to a fermentation tank for fermentation. After being exposed to the sun and dew, the unique flavor of broad bean paste is formed.

[0003] Once the fermented soybean paste is made, it will be transferred away. A small amount of fermented soybean paste will adhere to the inner wall of the fermentation tank. Before cleaning the fermentation tank, the fermented soybean paste on the inner wall needs to be scraped off to facilitate the cleaning operation. Currently, the scraping method is done manually, which has low scraping efficiency. In addition, the fermentation tank is generally long, and the manual labor intensity is high, which is not conducive to improving the production efficiency of fermented soybean paste. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides a scraping structure that can effectively improve scraping efficiency and reduce manual labor intensity.

[0005] To achieve the above objectives, the present invention employs the following technology:

[0006] A scraping structure, comprising:

[0007] The fermentation tank includes a rectangular bottom, side plates that are vertically arranged on both sides of the bottom and oriented towards the length of the bottom, end plates that can be detached at both ends of the bottom, and guide rails that are arranged on the top of the side plates and oriented towards the length of the bottom.

[0008] The mounting plate is positioned facing the width of the tank bottom. The bottom of the mounting plate is equipped with a gantry frame, and both ends of the mounting plate are equipped with guide wheels that cooperate with the guide rail. This is used to mount the mounting plate above the fermentation tank and to move the mounting plate along the guide rail.

[0009] There are two sets of top rods, which slide opposite each other along the length of the mounting plate on both sides of the portal frame;

[0010] The first scraper, two sets, is set perpendicular to the mounting plate and is respectively connected to the far end of the corresponding top rod;

[0011] The drive unit, located inside the gantry frame, is used to drive two sets of top rods to move towards each other along the length of the mounting plate.

[0012] Furthermore, the top of the portal frame is positioned along the length of the mounting plate, and the two ends of the portal frame are fitted with cover plates. Inside the portal frame, there is a pair of push plates, which are set parallel to the side of the portal frame. The push plates are respectively connected to the beginning of the corresponding top rod, and the drive unit is located between the two push plates.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up guide wheels, guide rails and mounting plates, and with the action of the first scraper, operators no longer need to manually scrape along the length of the fermentation tank. Instead, by pushing the mounting plate, the first scraper is driven to continuously scrape the inner wall of the side plate, which effectively improves the scraping efficiency.

[0015] 2. The installation structure of the first and second scrapers is simple and easy to disassemble and assemble, making it convenient to replace and clean the first and second scrapers. At the same time, through the cooperation of the first and second scrapers, the inner wall of the side plate and the bottom of the pool can be scraped without dead angles, with good scraping effect and high scraping efficiency.

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0024] This application provides a scraping structure, such as Figures 1-5 As shown, it includes: fermentation tank 1, mounting plate 2, top rod 3, first scraper 4, and drive unit 5.

[0025] Among them, such as Figure 1 and Figure 2 As shown, the fermentation tank 1 includes a rectangular tank bottom 11, with side plates 12 vertically arranged on both sides of the tank bottom 11 and facing the length direction of the tank bottom 11. End plates 13 are detachably provided at both ends of the tank bottom 11 by bolts. During unloading, the end plates 13 can be removed to improve unloading efficiency. The top of the side plates 12 is provided with guide rails 14 arranged facing the length direction of the tank bottom 11. The two guide rails 14 are channel steel structures and are arranged facing each other.

[0026] like Figures 2-4 As shown, the mounting plate 2 is positioned in the width direction of the tank bottom 11. The top of the mounting plate 2 is provided with a handle 26, and the bottom is provided with a gantry frame 21. At least two connecting shafts 25 are vertically provided at the bottom of both ends of the mounting plate 2. The at least two connecting shafts 25 at both ends are arranged in an array along the length direction of the tank bottom 11. The lower end of the connecting shaft 25 is coaxially rotatably fitted with a guide wheel 22. The guide wheels 22 at both ends of the mounting plate 2 respectively abut against the bottom of the corresponding guide rail 14 groove. The mounting plate 2 is erected above the fermentation tank 1 through the cooperation of the guide wheels 22 and the guide rail 14.

[0027] like Figures 2-4 As shown, there are two sets of top rods 3, and multiple top rods 3 can be set in each set to provide multi-point support for the first scraper 4, so that the first scraper 4 is evenly stressed and the scraping effect of the fermented bean paste is improved. In this embodiment, there are two top rods 3 in each set. The two sets of top rods 3 are slidably inserted into both sides of the gantry frame 21 along the length direction of the mounting plate 2. The two top rods 3 in each set are arranged in an array along the height direction of the pool bottom 11. Correspondingly, the axes of each top rod 3 are set in the same plane.

[0028] like Figure 1 and Figure 3 As shown, there are two sets of first scrapers 4, which are used to scrape the inner wall of the side plate 12. The first scrapers 4 are set perpendicular to the mounting plate 2 and are respectively connected to the far end of the corresponding top rod 3.

[0029] like Figure 3 and Figure 4 As shown, the drive unit 5 is located inside the gantry frame 21 and is used to drive the two sets of top rods 3 to move towards each other along the length of the mounting plate 2.

[0030] When applying, such as Figures 1-5As shown, after the fermented soybean paste is unloaded, the end plate 13 is removed. The operator aligns the guide wheels 22 at both ends of the mounting plate 2 with the ends of the guide rail 14 and pushes the guide wheels 22 against the bottom of the groove of the guide rail 14. The operator operates the drive unit 5 to move the two sets of push rods 3 closer to the inner wall of the side plates 12 along the length of the mounting plate 2 until one end of the first scraper 4 abuts against the inner wall of the side plate 12. The operator holds the handle 26 and pushes the mounting plate 2 along the length of the pool bottom 11 under the sliding cooperation of the guide wheels 22 and the guide rail 14, thereby driving the first scraper 4 to scrape off the fermented soybean paste attached to the inner wall of the side plate 12.

[0031] Operators no longer need to manually scrape along the length of the fermentation tank 1 with a scraper. Instead, by pushing the mounting plate 2, the first scraper 4 is driven to continuously scrape the inner wall of the side plate 12, effectively improving scraping efficiency. In addition, the sliding cooperation between the guide wheel 22 and the guide rail 14 makes the scraping process simple and labor-saving, greatly saving the operator's physical strength. At the same time, during the scraping process, the sliding cooperation between the guide wheel 22 and the guide rail 14 can effectively position the mounting plate 2 to ensure that the fermented bean paste is scraped clean.

[0032] Specifically, such as Figures 2-5 As shown, the top of the portal frame 21 faces the length direction of the mounting plate 2. Cover plates 23 are attached to both ends of the portal frame 21. A pair of push plates 24 are provided inside the portal frame 21, parallel to the sides of the portal frame 21. The push plates 24 are respectively connected to the beginning of the corresponding top rod 3. A spring 31 is fitted onto the top rod 3, connecting the push plate 24 to the side of the portal frame 21. The drive unit 5 includes a rotating shaft 51 facing the width direction of the mounting plate 2 and passing through the cover plates 23 at both ends of the portal frame 21. The rotating shaft 51 is located at the center of both sides of the portal frame 21 and rotates around its own axis. A double-center cam 52 is provided on the rotating shaft 51, with the two centers facing opposite directions. The double-center cam 52 is located between the two push plates 24. When the spring 31 is in its natural state, the distance between the two push plates 24 is less than the distance between the two centers of the double-center cam 52.

[0033] When it is necessary for the push rod 3 to approach and abut against the corresponding side plate 12, rotating the rotating shaft 51 will drive the tips of the double-pointed cam 52 to abut against the corresponding push plate 24. As the rotating shaft 51 continues to rotate, the two tips of the double-pointed cam 52 will push the push plate 24, causing the two sets of push rods 3 to approach and abut against the inner walls of the two side plates 12 along the length of the mounting plate 2. The setting of the rotating shaft 51, and through the cooperation between the spring 31 and the double-pointed cam 52 and the push plate 24, can convert the rotational movement of the rotating shaft 51 into the synchronous movement of the two push rods 3 towards each other along their own axes. The overall structure is relatively compact, does not require a separate drive mechanism to drive the movement of the push rods 3, and has a lower cost.

[0034] Correspondingly, such as Figure 5 As shown, a handwheel 53 can be installed at one end of the rotating shaft 51, and the operator can rotate the rotating shaft 51 by turning the handwheel 53.

[0035] Correspondingly, due to the action of the spring 31, when one end of the first scraper 4 abuts against the side plate 12, in order to prevent the spring 31 from stretching and causing the push plate 24 to push the double-center cam 52, it is necessary to fix the rotating shaft 51. A locking mechanism 8 can be set on the rotating shaft 51. Specifically, such as... Figures 3-5 As shown, the locking mechanism 8 includes a mating ring 54 coaxially mounted on the rotating shaft 51. The mating ring 54 is located between the handwheel 53 and the adjacent cover plate 23 of the handwheel 53. A pin 55 is slidably inserted through the mating ring 54 along the axial direction of the rotating shaft 51. A pin hole 56 is provided on the cover plate 23 along the axial direction of the rotating shaft 51 for inserting the pin 55. When the rotating shaft 51 is rotated, causing one end of the first scraper 4 to abut against the side plate 12, the pin hole 56 and the pin 55 become coaxial. At this time, inserting the pin 55 into the pin hole 56 can lock the rotating shaft 51. The above locking method has a lower cost while meeting the usage requirements. In addition to the structure of the locking mechanism 8 in this embodiment, other methods such as clamps and electromagnetic brakes can also be used.

[0036] To improve scraping effectiveness and convenience, such as Figure 1 and Figure 4 As shown, support plates 6 can be connected to the distal ends of both sets of top rods 3. The support plates 6 are set perpendicular to the mounting plate 2, and the support plates 6 form a predetermined angle with the side plates 12, which is 20°~30°. The first scraper 4 faces the length direction of the support plate 6 and is set parallel to the support plate 6. The first scraper 4 and the support plate 6 are connected by bolts. During scraping, the angle formed by the first scraper 4 and the side plate 12 is the same as the angle formed by the support plate 6 and the side plate 12. The first scraper 4 scrapes at an angle, which can improve the contact area and pressure distribution of the scraped material. If the first scraper 4 scrapes perpendicular to the side plate 12, it may just be a direct scraping. However, scraping at an angle will generate a certain tangential force, which helps the material to be removed more smoothly, reduces residue, and reduces the wear of the first scraper 4, thus improving its service life. At the same time, after scraping, the first scraper 4 can be directly removed for cleaning, which has high convenience.

[0037] Specifically, such as Figures 3-6As shown, a second scraper 7 perpendicular to the pool bottom 11 is provided below the support plate 6. The second scraper 7 has folded plates 71 at both ends, forming an isosceles trapezoidal structure with the folded plates 71 and the second scraper 7. The included angle between the folded plates 71 and the second scraper 7 is 110°~120°, matching the angle formed by the support plate 6 and the side plate 12. A first positioning hole 72 is provided on the folded plate 71. Positioning grooves 61 matching the folded plates 71 are provided on the lower sides of the two support plates 6. Specifically, the height of the positioning groove 61 is equal to the thickness of the folded plate 71, and the length of the positioning groove 61 is equal to the length of the folded plate 71. The positioning groove 61 extends through... One end and bottom of the support plate 6 have a mounting hole 62 at the bottom of the positioning groove 61 for tightening bolts; when the two folding plates 71 are fitted into the positioning groove 61, the bottom surface of the second scraper 7 is coplanar with the bottom surface of the support plate 6, the first positioning hole 72 coincides with the mounting hole 62, the side surface of the folding plate 71 is coplanar with the side surface of the support plate 6, and the bottom of the first scraper 4 is provided with a second positioning hole 41. When the two folding plates 71 are fitted into the positioning groove 61, and the first scraper 4 is attached to the support plate 6 and the folding plate 71, and the bottom surface of the first scraper 4 is coplanar with the bottom surface of the second scraper 7, the second positioning hole 41 coincides with the first positioning hole 72 and the mounting hole 62.

[0038] When installing the first scraper 4 and the second scraper 7, place the folded plates 71 at both ends of the first scraper 4 into the corresponding positioning grooves 61. Through the cooperation of the folded plates 71 and the positioning grooves 61, the second scraper 7 can be quickly positioned to the installation position, that is, the bottom surface of the second scraper 7 is coplanar with the bottom surface of the support plate 6, the side surface of the folded plate 71 is coplanar with the side surface of the support plate 6, and the first positioning hole 72 coincides with the mounting hole 62. Then, attach the first scraper 4 to the support plate 6 and the folded plate 71, and make the bottom surface of the first scraper 4 coplanar with the bottom surface of the second scraper 7. At this time, the second positioning hole 41 coincides with the first positioning hole 72 and the mounting hole 62. Then tighten the bolts to complete the installation of the first scraper 4 and the second scraper 7. Correspondingly, the other positions of the first scraper 4 are connected to the support plate 6 by bolts. The installation structure of the first scraper 4 and the second scraper 7 is simple and easy to disassemble and assemble, making it convenient to replace and clean the first scraper 4 and the second scraper 7. At the same time, through the cooperation of the first scraper 4 and the second scraper 7, the inner wall of the side plate 12 and the bottom of the pool 11 can be scraped without dead angles, with good scraping effect and high scraping efficiency.

[0039] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
