AI Technical Summary
Existing propolis mixing devices tend to have material adhering to the side walls of the mixing tank after mixing, requiring manual cleaning and making them inconvenient to use.
A device for timely cleaning of propolis mixing is designed. By setting through holes and rods on the mixing shaft, and installing counterweights and scrapers on the rods, the centrifugal force of the counterweights moves them away from the mixing shaft at high speed and closer to the mixing shaft at low speed, thereby automatically scraping off the material from the inner wall of the mixing tank.
It enables automatic cleaning of the mixing tank, reduces manual intervention, and improves ease of use.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of propolis processing equipment technology, and in particular to a propolis stirring device. Background Technology
[0002] In the processing of propolis, it is sometimes necessary to mix propolis with other materials, such as mixing propolis with ethanol to purify it; or mixing propolis with honey to produce propolis containing honey to meet the needs of some customers. The equipment used for mixing propolis is called a propolis mixing device.
[0003] The propolis mixing device includes a mixing tank with an upper inlet and a lower outlet. The mixing tank has a shaft hole on its upper surface, into which a mixing shaft is inserted. A mixing motor is mounted on the mixing tank and connected to the mixing shaft. Mixing blades are also connected to the mixing shaft.
[0004] After each mixing, materials such as propolis will stick to the side wall of the mixing tank. In the prior art, the mixing blades are fixedly installed on the mixing shaft and do not have a cleaning function. Cleaning these materials still requires manual cleaning, which is inconvenient to use. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a convenient propolis mixing device that can automatically clean the material adhering to the mixing tank – a timely cleaning propolis mixing device.
[0006] The technical solution adopted by this utility model is as follows: a propolis stirring device for timely cleaning, including a stirring tank, the stirring tank having an upper inlet and a lower outlet, a shaft hole on the upper part of the stirring tank, a stirring shaft inserted into the shaft hole, a stirring motor installed on the stirring tank, the stirring motor connected to the stirring shaft, and stirring blades connected to the stirring shaft; characterized in that: the stirring shaft has a through hole extending from left to right, and a through rod is installed in the through hole, the stirring blades being the through rod, a counterweight installed at one end of the through rod, and a counterweight at the other end of the through rod. A scraper is installed at one end, and the scraper has rubber scraping blocks that cooperate with the side of the mixing tank. A spring is also installed on the rod to move the counterweight towards the mixing shaft. When the mixing shaft rotates at high speed, the counterweight moves away from the mixing shaft due to the centrifugal force, and the scraper does not contact the inner wall of the mixing tank. When the mixing shaft rotates at low speed, the centrifugal force of the counterweight decreases, and the counterweight moves closer to the mixing shaft under the action of the spring. The scraper then contacts the inner wall of the mixing tank and scrapes and cleans the inner wall of the mixing tank.
[0007] The beneficial effects of this utility model are: such a propolis mixing device has the advantages of being able to clean the material adhering to the mixing tank by itself and being easy to use. Attached Figure Description

[0012] The present invention will now be further described with reference to the accompanying drawings.
[0013] like Figure 1 , 2 As shown, a propolis mixing device for timely cleaning includes a mixing tank 1, which has an inlet 11 at the top and an outlet 12 at the bottom. The mixing tank has a shaft hole on its top, into which a mixing shaft 2 is inserted. A mixing motor 3 is mounted on the mixing tank, connected to the mixing shaft, and mixing blades are connected to the mixing shaft. The mixing shaft has a through hole 21 extending from left to right, into which a through rod 4 is installed. The mixing blades are the through rods. A counterweight 5 is installed at one end of the through rod, and a scraper 6 is installed at the other end. The scraper has a function to cooperate with the side of the mixing tank. The rubber scraper 61 has a spring 7 installed on the rod to move the counterweight towards the stirring shaft. When the stirring shaft rotates at high speed, the counterweight moves away from the stirring shaft due to the centrifugal force of the counterweight, meaning the force generated by the counterweight is greater than the force of the spring. The scraper does not contact the inner wall of the mixing tank. When the stirring shaft rotates at low speed, the centrifugal force of the counterweight decreases, meaning the force generated by the counterweight is not greater than the force of the spring. Under the action of the spring, the counterweight moves closer to the stirring shaft, and the scraper contacts the inner wall of the mixing tank to scrape and clean it.
[0014] The above-mentioned configuration of this utility model allows for the stirring of propolis during normal stirring, i.e., when the stirring shaft rotates at high speed. When stirring stops, the rotation of the stirring shaft changes from high speed to low speed. When the appropriate low speed is reached, the scraper can clean the inner wall of the stirring tank. That is, it automatically cleans the tank each time stirring stops, thus achieving the purpose of this utility model.
[0015] In one embodiment, the mass of the scraper is less than the mass of the counterweight.
[0016] In one embodiment, the mass of the counterweight is 5 to 10 times the mass of the scraper.
[0017] This design ensures that the centrifugal force generated by the counterweight is greater than that generated by the scraper when the stirring shaft is rotating at a high speed.
[0018] In one embodiment, the stirring motor is connected to a power source via a switch, which has a high setting and a low setting. When the stirring motor is running at the high setting, the scraper does not clean the inner wall of the mixing tank; when the stirring motor is running at the low setting, the scraper cleans the inner wall of the mixing tank.
[0019] This invention is designed so that when the mixing tank needs to be cleaned, the low setting can be used to clean the mixing tank.
[0020] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
