Technical Field

[0001] This utility model relates to the field of hemp strip production technology, specifically a raw material cleaning device. Background Technology

[0002] In the production and processing of food ingredients such as sweet potato strips, cleaning the raw materials is an important step to ensure food hygiene and safety. Especially in the hilly areas of the south, sweet potatoes are a major economic crop and are often processed into various snack foods. The traditional preparation of sweet potato strips requires multiple processes such as cleaning, steaming, shaping, and drying. Among these, the effectiveness of cleaning the raw materials directly affects the quality of the final product.

[0003] Currently, common raw material cleaning methods mostly employ fixed brushing or manual rinsing, which suffer from problems such as uneven cleaning, low efficiency, and high labor intensity. Fixed brushing devices are difficult to fully cover and clean raw materials, especially those piled up at the bottom or edge of containers, where the cleaning effect is poor and impurities are easily left behind. Utility Model Content

[0004] The purpose of this invention is to provide a raw material cleaning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material cleaning device, comprising a box body, with a discharge port fixedly connected to the bottom center of the box body, and four support legs fixedly connected to the bottom edge of the box body. A cover plate is fitted on the top of the box body, with three limiting grooves annularly formed inside the cover plate. A feed port is fixedly connected to the top of the cover plate, and three brushing mechanisms are annularly installed on the cover plate. Each brushing mechanism includes a support plate, rollers, and a guide frame. A first motor is fixedly connected to the bottom of the support plate, and the drive end of the first motor passes through the support plate and is fixedly connected to a disc. A roller is rotatably connected to the top of the disc via a bearing. A guide frame is fitted around the rollers, and crossbars are fixedly connected to both sides of the guide frame. An anti-detachment frame is fitted around the crossbars. A support plate is fixedly connected to one end of one of the crossbars, and a second motor is fixedly connected to the top of the support plate. A limiting block is fixedly connected to the bottom of the support plate. The drive end of the second motor passes through the support plate and the limiting block and is fixedly connected to a brush.

[0006] As a preferred technical solution of this utility model, the crossbar and the anti-detachment frame are slidably connected, and there are two anti-detachment frames, both of which are fixed to the top of the support plate.

[0015] In the attached diagram, all identical reference numerals refer to the same components.

[0016] Example 1 Please see Figures 1 to 3This utility model provides a raw material cleaning device, including a box body 1. A discharge port 11 is fixedly connected to the center of the bottom of the box body 1, and four support legs 12 are fixedly connected to the bottom edge of the box body 1. A cover plate 2 covers the top of the box body 1. Three limiting grooves 3 are annularly formed inside the cover plate 2. A feed port 4 is fixedly connected to the top of the cover plate 2. Three brushing mechanisms 5 are annularly mounted on the cover plate 2. Each brushing mechanism 5 includes a support plate 51, rollers 52, and guide frames 53. A first motor 511 is fixedly connected to the bottom of the support plate 51. The drive end of the first motor 511 passes through the support plate 51 and is fixedly connected to a disc 512. The top of the disc 512 is rotatably connected to a bearing. A roller 52 is fitted with a guide frame 53. A crossbar 54 is fixed to both sides of the guide frame 53. An anti-detachment frame 55 is fitted to the outside of the crossbar 54. A support plate 56 is fixed to one end of one of the crossbars 54. A second motor 57 is fixed to the top of the support plate 56, and a limit block 58 is fixed to the bottom of the support plate 56. The drive end of the second motor 57 passes through the support plate 56 and the limit block 58 and is fixed to a brush 59. A disc 512 is located between the two anti-detachment frames 55. The brush 59 is located inside the housing 1. The crossbar 54 and the anti-detachment frame 55 are slidably connected. There are two anti-detachment frames 55, and both anti-detachment frames 55 are fixed to the top of the support plate 51.

[0017] In this embodiment, the sliding connection between the crossbar 54 and the anti-detachment frame 55 forms a precise linear guide pair, ensuring that the reciprocating linear motion transmitted from the guide frame 53 can proceed smoothly and without jamming. The two anti-detachment frames 55 are symmetrically arranged and fixed to the top of the support plate 51, providing balanced support and constraint for the crossbar 54 and preventing it from deflecting or twisting during movement. The design of the brush 59 located inside the housing 1 ensures that the range of action of its composite motion completely covers the cleaning cavity, ensuring no cleaning dead corners. The core principle of this embodiment is to construct a stable and reliable planar reciprocating motion execution unit, which converts the rotational motion of the first motor 511 into linear motion through components such as the disc 512, roller 52, guide frame 53, and crossbar 54, and ultimately drives the brush 59 to work.

[0018] Example 2 Please see Figure 3 The support plate 51 is fixed to the outer annular surface of the cover plate 2, and there are three support plates 51. The limiting block 58 has an I-shaped structure and is slidably connected inside the limiting groove 3. The guide frame 53 has a guide groove inside, and the roller 52 is located in the guide groove and is adapted to the guide groove.

[0019] In this embodiment, three support plates 51 are annularly and fixedly connected to the periphery of the cover plate 2, thereby forming a uniform and comprehensive dynamic cleaning field within the housing 1. The sliding cooperation between the I-shaped limiting block 58 and the annular limiting groove 3 restricts the reciprocating linear motion trajectory of the brushing mechanism 5 to a preset annular path, ensuring motion accuracy and equipment operation coordination. On the other hand, the I-shaped structure has excellent anti-overturning ability, effectively resisting the radial force and overturning moment generated when the brush 59 is working, enhancing the rigidity and stability of the entire motion system. The precise fit between the roller 52 and the internal guide groove of the guide frame 53 is the key to converting rotational motion into linear motion. The principle is to use the rolling and constraint of the roller 52 in the closed guide groove to convert the fixed-axis rotation of the disc 512 into the precise linear reciprocating motion of the guide frame 53 without slippage. The transmission efficiency is high and the wear is small. The core principle of this embodiment is to achieve the coordinated, stable and efficient operation of multiple cleaning units through the symmetrical layout in space and the precise design of key motion pairs, so as to complete the thorough cleaning of materials.

[0020] The first motor 511 and the second motor 57 are both model YE2.

[0021] Working principle: When using this device, firstly, the raw materials such as sweet potatoes to be cleaned are put into the box 1 through the feed port 4, and an appropriate amount of cleaning water is added. Then, the first motor 511 and the second motor 57 on the three brushing mechanisms 5 are started. The first motor 511 drives the disc 512 to rotate, which drives the roller 52 on its top to make a circular motion. Since the roller 52 is fitted in the guide groove inside the guide frame 53, and the guide groove is adapted to the roller 52, the circular motion of the roller 52 is converted into the horizontal reciprocating motion of the guide frame 53 along its length. The guide frame 53 drives the crossbars 54 fixed on both sides to move. The crossbars 54 slide smoothly under the constraint of the anti-detachment frame 55. The support plate 56, the limiting block 58, the second motor 57, and the brush 59 fixed to the end of one of the crossbars 54 also move horizontally and reciprocating synchronously. During this process, the I-shaped limiting block 58 slides within the limiting groove 3 of the cover plate 2, ensuring the stability and accuracy of the trajectory of the entire brushing mechanism 5. At the same time, the second motor 57 drives the brush 59 to rotate at high speed. Therefore, the brush 59 has a composite motion of horizontal reciprocating movement and high-speed rotation during the cleaning process. The three brushing mechanisms 5 arranged in a circle work simultaneously, and their brushes 59 form a dynamic and comprehensive cleaning network within the box 1, which can effectively reach the raw materials in all positions within the box 1, especially the bottom and edge areas. The reciprocating movement of the brush 59 also serves to turn the materials, so that all surfaces of the raw materials can be thoroughly brushed. After cleaning, the first motor 511 and the second motor 57 are turned off, and the sewage and impurities can be discharged through the discharge port 11, completing the cleaning process.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
