Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning brush technology, specifically a test grinding cleaning brush. Background Technology
[0002] Currently, the Buhler experimental mill on the market is designed for wheat milling. It is a three-core, three-skin mill and is a widely relied-upon and highly regarded automated mill for wheat breeding. However, for breeding purposes, small-dose (1-2kg) milling of varietal samples is very frequent. Timely cleaning of experimental vessels with a cleaning brush helps maintain the hygienic environment of the experimental equipment, reduces the accumulation of harmful bacteria or chemicals, and reduces waste caused by damage or contamination of the vessels through effective cleaning.
[0003] Cleaning instruments is a time-consuming and labor-intensive task. Existing test mill cleaning brushes suffer significant bristle wear after use and need to be replaced. However, the replacement of existing test mill cleaning brushes is quite complicated, so they are generally disposable and discarded after use, resulting in high cleaning costs and serious resource waste. Therefore, a test mill cleaning brush is proposed to address the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a test grinding cleaning brush to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A test grinding cleaning brush includes a handle, a fixing frame, a sliding rod, a nut, and a brush sleeve. A fixing shell is fixedly connected to one side of the fixing frame, a return spring is fixedly connected to one side of the fixing shell, and a sliding rod is fixedly connected to one side of the fixing shell. A roller is provided on the outer side of the sliding rod. The roller includes a locking hole, a sliding groove, and a cylindrical body. A locking hole and a sliding groove are provided on the inner side of the cylindrical body. A sliding block is provided on the outer side of the sliding rod. A locking rod is fixedly connected to one side of the sliding block, and a return spring is in contact with one side of the sliding block.
[0007] Preferably, a fixing block is fixedly connected to one side of the handle, and a fixing frame is fixedly connected to one side of the fixing block. There are two fixing frames, and a silicone plate is fixedly connected to one side of the lower fixing frame.
[0008] Preferably, there are eight locking holes, the outer side of the locking rod is disposed in the locking hole, and the outer side of the sliding rod is disposed inside the sliding groove.
[0009] Preferably, a brush sleeve is provided on the outer side of the cylinder.
[0010] Preferably, one end of the sliding rod is fixedly connected to a threaded rod, and a nut is screwed onto the outer side of the threaded rod.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this invention, a sliding block and a nut are used to limit the range of motion of the brush while working with a return spring. When the nut is removed, the return spring pushes the roller with the brush sleeve to one side through the sliding block, simplifying the brush sleeve replacement process. This allows the cleaning brush to only require the replacement of the brush sleeve, making the handle reusable and saving cleaning costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.
[0018] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0019] Please see Figure 1-2 This utility model provides a technical solution:
[0020] A test grinding cleaning brush includes a handle 1, a fixing frame 4, a sliding rod 10, a nut 12, and a brush sleeve 13. A fixing shell 5 is fixedly connected to one side of the upper fixing frame 4, a return spring 6 is fixedly connected to one side of the fixing shell 5, and the sliding rod 10 is fixedly connected to one side of the fixing shell 5. A roller 9 is provided on the outer side of the sliding rod 10. The roller 9 includes a locking hole 901, a sliding groove 902, and a cylinder 903. The locking hole 901 and the sliding groove 902 are opened on the inner side of the cylinder 903. A sliding block 7 is provided on the outer side of the sliding rod 10. A locking rod 8 is fixedly connected to one side of the sliding block 7, and the return spring 6 is in contact with one side of the sliding block 7.
[0021] A fixing block 2 is fixedly connected to one side of the handle 1, and a fixing bracket 4 is fixedly connected to one side of the fixing block 2. There are two fixing brackets 4. A silicone plate 3 is fixedly connected to one side of the lower fixing bracket 4. Different structures can be used for cleaning. There are eight locking holes 901. The outer side of the locking rod 8 is set in the locking hole 901, and the outer side of the sliding rod 10 is set inside the sliding groove 902 to prevent the roller 9 from being installed crookedly. A brush sleeve 13 is set on the outer side of the cylinder 903. Only the brush sleeve 13 needs to be replaced without changing other structures. A threaded rod 11 is fixedly connected to one end of the sliding rod 10. A nut 12 is screwed on the outer side of the threaded rod 11 to limit the range of motion of the roller 9 and prevent the roller 9 from moving randomly during the cleaning process, which would lead to incomplete cleaning.
[0022] Workflow: When cleaning the experimental mill, first place the brush sleeve 13 on the outside of the cylinder 903, then rotate the nut 12 to remove it from the threaded rod 11. Next, place the sliding groove 902 of the roller 9 on the outside of the sliding rod 10. Then slide the cylinder 903 to the left, aligning the locking hole 901 with the locking rod 8, until the cylinder 903 contacts the sliding block 7. Continue sliding the cylinder 903 to the left, causing the cylinder 903 to compress the return spring 6 through the sliding block 7. When one side of the sliding block 7 contacts one side of the fixed shell 5, tighten the nut 12. Screw it back onto the outside of the threaded rod 11. The compressed return spring 6 will push the cylinder 903 toward the nut 12, so that the nut 12 contacts the cylinder 903. Then, hold and move the handle 1. The handle 1 will drive the brush sleeve 13 or silicone plate 3 to clean the experimental mill through the fixing block 2 and the fixing bracket 4. When the brush sleeve 13 is severely worn, turn the nut 12 to remove the nut 12 from the threaded rod 11. The cylinder 903 will move away from the fixing shell 5 under the elastic force of the return spring 6, making it convenient for the staff to quickly remove the roller 9 and then replace the brush sleeve 13 on the outside of the roller 9.
