Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning devices, and in particular to a bottom grass cleaning device. Background Technology
[0002] Currently, in the traditional baijiu industry, due to the unique nature of brewing technology and the complex and diverse production environment, most brewing operations are still primarily manual, and full automation is not yet possible. Especially in traditional koji-making, we use straw to separate the koji cakes when stacking them together to increase the fermentation temperature. The bottom straw serves as the base for the koji cakes during fermentation, isolating them from direct contact with the ground and providing warmth and moisture. Furthermore, the initial turning, secondary turning, and dismantling of the koji require cleaning the original bottom straw and laying down new straw. This cleaning process generates dust, impacting the production environment, and is time-consuming and labor-intensive, significantly increasing the workload for workers at each stage and raising the risk of occupational diseases.
[0003] In traditional methods, some manufacturers use equipment such as grass catchers, turf removers, and loaders to clean the substrate grass. However, the aforementioned equipment has the following drawbacks:
[0004] 1) Because the bottom grass is looser than the ground, it cannot be completely removed by a ground removal machine. At the same time, the friction with the floor tiles is large, resulting in extremely low safety. 2) Because the bottom grass in the fermentation chamber contains a large amount of broken koji residue, it cannot be completely removed by a grass grabber. 3) Because the bottom grass is highly connected, and the loader has no claws, it cannot break the bottom grass or hold it firmly in the loader.
[0005] Therefore, there is an urgent need for a device to solve the technical problems mentioned above. Utility Model Content
[0006] Based on this, this application provides a bottom grass cleaning device that can effectively solve the problems of existing devices that cannot clean the bottom grass thoroughly, have poor safety, and low work efficiency, thereby achieving the effects of completely cleaning the bottom grass, high safety, saving labor costs, and improving work efficiency.

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0042] In existing technologies, equipment such as grass catchers, soil removers, and loaders are used to clean the substrate. However, because substrate is looser than the soil, soil removers cannot completely remove it, and the friction with the paving stones is significant, resulting in extremely low safety. Since the substrate in the fermentation chamber contains a large amount of broken koji residue, grass catchers also cannot completely remove it. Because the substrate is highly interconnected, and loaders lack claws, they cannot break the substrate or hold it securely in the shovel. Therefore, this application provides a substrate cleaning device that, through the cooperation of a bucket 1, a power mechanism 2, and a weeding mechanism 3, achieves thorough substrate cleaning, high safety, labor cost savings, and improved work efficiency.
[0043] The following is a detailed description of the substrate cleaning device provided in this embodiment, with reference to the accompanying drawings. Figures 1-2 As shown, it includes: a bucket 1 for loading the cleaned bottom grass, and a power mechanism 2 and a weeding mechanism 3 are provided on the bucket 1; the power mechanism 2 is used to provide power support for the bucket 1 so that the bucket 1 moves forward automatically; the weeding mechanism 3 is used to cooperate with the bucket 1 to clean the bottom grass.
[0044] Specifically, the bucket 1 includes a base plate 11, a vertical plate 12 fixedly connected to the base plate 11, and side plates 13 fixedly connected to opposite sides of the base plate 11. The base plate 11, vertical plate 12, and side plates 13 are all made of 304 stainless steel and are 4cm thick. The base plate 11 can be inclined at 13° to the ground and is rectangular, with a width of 60cm and a length of 1m. The vertical plate 12 is perpendicular to the ground, also rectangular, with a width of 60cm and a length of 1cm. The side plates are triangular. The base plate 11, vertical plate 12, and two side plates 13 form a loading cavity for loading the cleared substrate. A power mechanism 2 is located on the side of the vertical plate 12 away from the side plates 13, providing power to the bucket 1 and enabling it to move forward automatically. A weeding mechanism 3 is located on the bucket 1 and works in conjunction with it to clear the substrate.
[0045] The above operation, through the cooperation of bucket 1, power mechanism 2 and weeding mechanism 3, achieves the cleaning of bottom grass, which can achieve the effects of complete bottom grass cleaning, high safety and saving labor costs.
[0046] Preferred, refer to Figures 1-2 As shown, the power mechanism 2 includes a housing 21 disposed on the bucket 1 and a power assembly 22 disposed on the housing 21; the housing 21 is used to provide mounting support for the power assembly 22; the power assembly 22 is used to provide power support for the bucket 1, so that the bucket 1 moves forward automatically.
[0047] Specifically, the power mechanism 2 includes a housing 21 fixedly connected to the side of the vertical plate 12 away from the side plate 13 and a power component 22 disposed in the housing 21; the housing 21 is rectangular, with a length of 30cm, a width of 60cm, and a height of 1m; and the housing 21 is made of 304 stainless steel; at the same time, a control panel can be installed on the outside of the housing 21, which provides installation support for the power component 22 and enables control of the power component 22.
[0048] In one feasible approach, refer to Figures 1-2 As shown, the power assembly 22 includes a control motor 221 disposed in the housing 21, a rolling wheel 222 mounted on the lower end of the housing 21, and a transmission unit 223 disposed between the control motor 221 and the rolling wheel 222; the control motor 221 is used to control the rotation of the rolling wheel 222; the rolling wheel 222 is controlled by the control motor 221 to drive the bucket 1 to move forward automatically; the transmission unit 223 is used to realize the transmission connection between the control motor 221 and the rolling wheel 222.
[0049] Specifically, the power assembly 22 includes a control motor 221 housed within the chassis 21, rolling wheels 222 mounted on the lower end of the chassis 21, and a transmission unit 223 positioned between the control motor 221 and the rolling wheels 222. The control motor 221 can be 1500W, and the battery installed inside the control motor 221 can be 72V 130AH. Two rolling wheels 222 are provided, both solid. A rolling shaft 214 is mounted on the lower end face of the chassis 21, with the two rolling wheels 222 mounted at opposite ends of the rolling shaft 214. The control motor 221 controls the rotation of the rolling shaft 214 via the transmission unit 223, which in turn drives the rolling wheels 222 to rotate. During the rotation of the rolling wheels 222, the bucket 1 moves forward automatically.
[0050] In another possible approach, refer to Figures 1-2 As shown, the transmission unit 223 includes a first transmission component disposed on the control motor 221 and a second transmission component that cooperates with the first transmission component for transmission; the first transmission component is used to be controlled by the control motor 221 to drive the second transmission component to rotate; the second transmission component is used to be controlled by the first transmission component to drive the rolling wheel 222 to rotate.
[0051] The first transmission component can be a first gear; the second transmission component can be a second gear.
[0052] Specifically, the transmission unit 223 includes a first gear fixedly connected to the output shaft of the control motor 221 and a second gear meshing with the first gear. The first gear can be driven to rotate by the output shaft of the control motor 221. Since the first gear and the second gear mesh, the first gear can drive the second gear to rotate. Here, the rolling shaft 214 passes through the second gear and is fixedly connected to it; therefore, the second gear can drive the rolling shaft 214 to rotate, the rolling shaft 214 drives the rolling wheel 222 to rotate, the rolling wheel 222 drives the housing 21 to move forward automatically, and the housing 21 drives the bucket 1 to move forward automatically. It should be noted that the first and second transmission components here can also be other transmission components, as long as they can achieve the transmission connection between the control motor 221 and the rolling wheel 222; no specific restrictions are imposed here.
[0053] The above operation starts the control motor 221, which rotates the output shaft of the control motor 221, causing the first gear to rotate. The first gear can drive the second gear to rotate, which in turn drives the rolling shaft 214 to rotate. The rolling shaft 214 drives the rolling wheel 222 to rotate, which in turn drives the housing 21 to move forward automatically. The housing 21 then drives the bucket 1 to move forward automatically, thereby achieving control over the automatic forward movement of the bucket 1. This achieves a simple and labor-saving effect.
[0054] Preferably, refer to Figures 1-2As shown, the weeding mechanism 3 includes bucket teeth 31 and weeding components 32 disposed on the bucket 1; the bucket teeth 31 are used to scoop up the bottom grass and cooperate with the weeding components 32 to cut the bottom grass; the weeding components 32 are used to cooperate with the bucket teeth 31 to cut the bottom grass.
[0055] Specifically, the weeding mechanism 3 includes bucket teeth 31 and weeding components 32. The bucket teeth 31 are fixedly connected to the bottom plate 11 of the bucket 1 on the side away from the vertical plate 12. Five bucket teeth 31 are provided, and there is a gap between each two adjacent teeth to cooperate with the weeding components 32. While scooping up the bottom grass, the bucket teeth 31 cooperate with the weeding components 32 to cut the bottom grass. The side of the bucket teeth 31 near the bottom plate 11 is provided with a V-shaped opening, which is used to engage with the bottom plate 11 to achieve a fixed connection with the bottom plate 11.
[0056] In one feasible way, such as Figures 1-2 As shown, the weeding assembly 32 includes a weeding claw 321 rotatably connected to the housing 21 and a telescopic unit disposed on the bucket 1; the weeding claw 321 is used to cooperate with the bucket teeth 31 to cut the bottom grass; the telescopic unit is used to control the rotation of the weeding claw 321 so that the bucket 1 can be loaded with bottom grass and cooperate with the weeding claw 321 to cut the bottom grass.
[0057] Specifically, the weeding assembly 32 includes a weeding claw 321 and a telescopic unit. Two rotating bases 212 are fixedly connected to the upper end face of the housing 21 along its length and near its opposite sides, and a rotating shaft 213 is rotatably connected between the two rotating bases 212.
[0058] Here, the weeding claws 321 can be a single, wide-toothed claw, and multiple claws are provided, ideally four. All four weeding claws 321 are fitted onto and fixedly connected to the rotating shaft 213. Simultaneously, a fixed shaft 3211 is provided between the four weeding claws 321. The fixed shaft 3211 passes sequentially through the four weeding claws 321 and is fixedly connected to them. The fixed shaft 3211 provides further assurance for the synchronous movement of the four weeding claws 321. Each weeding claw 321 is arranged in a downward-curving arc, and the curvature can be set to 20 cm / m. Since there are five teeth 31, and gaps are provided between adjacent teeth, four gaps can be formed. The four weeding claws 321 can fall into these four gaps, cooperating with the teeth 31 to cut the weeds at the bottom.
[0059] In another possible way, such as Figures 1-2 As shown, the telescopic unit includes a telescopic component 322 and a weeding claw 321 with a connecting shaft 3212. The lower end of the telescopic component 322 is installed on the bucket 1 and the upper end is rotatably connected to the connecting shaft 3212, which is used to drive the weeding claw 321 to rotate.
[0060] The telescopic component 322 can be a pneumatic cylinder or a hydraulic cylinder. Taking a pneumatic cylinder as an example, the telescopic stroke of the pneumatic cylinder can be set to 250mm; the telescopic power can be set to 60W.
[0061] Specifically, a connecting shaft 3212 is provided between the four weeding claws 321. The connecting shaft 3212 passes through the four weeding claws 321 in sequence and is fixedly connected to the four weeding claws 321. There are two cylinders, which are respectively installed on the outer sides of the two side plates 13 facing away from each other. The lower ends of the two cylinders are on the same plane as the base plate 11, and the upper ends of the extension rods of the two cylinders are rotatably connected to the two ends of the connecting shaft 3212 after it passes through the weeding claws 321.
[0062] The above operation involves starting the cylinder when it is necessary to clean the bottom grass. The cylinder's extension rod descends, causing the weeding claw 321 to rotate downwards. This allows the weeding claw 321 to fall into the gap of the bucket teeth 31, thereby grabbing and cutting the bottom grass scooped up by the bucket teeth 31. The cut bottom grass is then placed in the cavity of the bucket 1, thus achieving the cleaning operation of the bottom grass. This results in a clean bottom grass with high work efficiency.
[0063] Preferably, refer to Figure 1 , Figure 2 As shown, a guide wheel 111 is provided at the bottom of the bucket 1 to guide the forward direction of the bucket 1.
[0064] Specifically, a guide wheel 111 is installed on the lower end face of the bottom plate 11 of the bucket 1, which can guide the forward direction of the bucket 1 and achieve the effect of positioning the entire cleaning device.
[0065] Preferably, refer to Figure 1 , Figure 2 As shown, a handle 211 is provided on the side of the housing 21 away from the bucket 1 for the operator to operate the housing 21; a handrail 3213 is provided at the upper end of the weeding claw 321 for the operator to lift the weeding claw 321.
[0066] Specifically, a handle 211 is fixedly connected to the side of the casing 21 away from the bucket 1. The handle 211 is U-shaped with its opening facing the casing 21, so that the operator can operate the casing 21 and achieve the effect of convenient operation.
[0067] A handle 3213 is fixedly connected to the upper end face of two adjacent weeding claws 321. The handle 3213 is U-shaped with an opening at the bottom, which is used by the staff to lift the weeding claws 321 to facilitate the control of the weeding claws 321.
[0068] It should also be noted that, through practical experience, the above-mentioned cleaning device can achieve the following effects:
[0069] 1) It can reduce the average physical stress of workers to 990N, which is less than 1772N before the equipment was used, thus making it easier for employees to operate the equipment.
[0070] 2) Automatic cleaning is achieved. The average time to clean the bottom straw of one fermentation silo is 11.13 minutes, which is less than the previous 27.05 minutes, thus greatly improving the work efficiency of employees.
[0071] 3) The use of this device can reduce the frequency of manual cleaning by 52 times, and reduce the amount of dust ingested by staff in the fermentation chamber.
[0072] The implementation principle of this embodiment is as follows: During use, the control motor 221 is started, causing its output shaft to rotate. This rotation drives the first transmission component to rotate, which in turn drives the second transmission component to rotate. The second transmission component then drives the rolling shaft 214 to rotate, which in turn drives the rolling wheel 222 to rotate. The rolling wheel 222 causes the housing 21 to move forward automatically, which in turn causes the bucket 1 to move forward automatically. Simultaneously, the telescopic component 322 is activated, causing its telescopic rod to descend and rotate the weeding claw 321 downwards. This allows the weeding claw 321 to be positioned in the gaps between the bucket teeth 31, thus gripping and cutting the bottom grass scooped up by the bucket teeth 31. The cut bottom grass is then placed inside the cavity of the bucket 1, achieving the bottom grass cleaning operation. This application achieves the effects of complete bottom grass cleaning, high safety, saving labor costs, and improving work efficiency.
[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0074] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
