Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of vegetable pickling, and particularly relates to a stirring device. BACKGROUND

[0002] Vegetable pickling refers to a method for preserving vegetables and imparting fresh taste to the vegetables by using high-concentration salt solution and lactic acid bacteria fermentation and pickling to improve the flavor of the vegetables. In the process of pickling vegetables, the vegetables need to be mixed with auxiliary materials to improve the taste and quality of the pickled vegetables.

[0003] At present, the mixing of vegetables and auxiliary materials is generally carried out by using a stirring device. For example, the patent with the announcement number "CN 214486692 U" discloses "a material stirring device for pickling sauerkraut". The device includes a stirring barrel. The lower part of the stirring barrel is a main material stirring cavity, which is provided with a main material stirring device. The main material stirring device includes a stirring shaft, which is driven by a first driving motor. The stirring shaft is provided with an upper stirring shaft and a lower stirring shaft. The upper stirring shaft and the lower stirring shaft are staggered by an angle of 45-70° on the stirring plane. The upper stirring shaft and the lower stirring shaft on the same side are connected by a flexible material sheet. A separate material stirring cavity is provided on the upper part of one side of the stirring cavity. The material stirring cavity is provided with a material stirring device and has a discharge port. The material stirring device is driven by a second driving motor, and the discharge port is opposite to the upper part of the middle position of the stirring shaft. The device can better realize the stirring and mixing of vegetables and auxiliary materials. However, the following problems exist. The mixing of vegetables and auxiliary materials mainly relies on the stirring of the flexible sheet. When the stirring intensity is insufficient, it is difficult to achieve the sufficient mixing of vegetables and auxiliary materials. When the stirring intensity is too large, the vegetables are easily damaged. In addition, the device is provided with the upper stirring shaft and the lower stirring shaft which are staggered and the flexible material sheet, so that the main material stirring device can obtain an effect similar to spiral lifting stirring to lift the sauerkraut at the bottom. However, the effect of lifting the vegetables upward is limited, which easily leads to the uneven mixing of the vegetables and auxiliary materials on the upper and lower sides, especially when the auxiliary materials are mixed into the liquid. UTILIZABLE CONTENT

[0004] The utility model aims to provide a stirring device to improve the uniformity of the mixing of vegetables and auxiliary materials.

[0005] The stirring device in the scheme comprises a base, a horizontally placed stirring cylinder is rotationally connected to the base, a feeding opening is arranged on the stirring cylinder, a hatch is arranged at the feeding opening to open and close the feeding opening; a stirring shaft is rotationally connected in the stirring cylinder, stirring blades are arranged on the stirring shaft in the stirring cylinder; the two ends of the stirring shaft extend out of the stirring cylinder, a motor is mounted at one end of the base, and the motor is fixedly connected with one end of the stirring shaft; a inner gear disc is fixedly connected with the end of the stirring shaft away from the motor, a sun gear is rotationally connected at the center of the inner gear disc and is fixedly connected with the end of the stirring shaft away from the motor, a plurality of planet gears which are in mesh with the inner gear disc and the sun gear are arranged in the inner gear disc, the plurality of planet gears are connected with the same planet carrier, and the planet carrier is rotationally connected to the base.

[0006] The working principle and beneficial effects of the scheme are as follows: in use, vegetables and auxiliary materials are put into the stirring cylinder through the feeding opening, and the feeding opening is closed by the hatch. Then the motor is started, the motor drives the stirring shaft to rotate, the stirring shaft drives the stirring blades on the stirring shaft to stir and mix the vegetables and auxiliary materials in the stirring cylinder on one hand. On the other hand, the stirring shaft drives the sun gear to rotate, since the sun gear is in mesh with the inner gear disc and the plurality of planet gears, the rotation of the sun gear will promote the planet gears to make planetary motion around the sun gear, at the same time, the planet carrier will also rotate, the rotation of the planet carrier will drive the stirring cylinder to rotate reversely relative to the stirring shaft. In this process, since the vegetables and auxiliary materials are jointly acted on by the stirring cylinder and the stirring blades, their positions will change constantly, avoiding uneven distribution of the vegetables and auxiliary materials in the up and down directions.

[0007] Further, the base is fixedly connected with an adjusting disc, and the inner gear disc and the planet carrier are both rotationally connected to the adjusting disc. The adjusting disc provides a stable support structure for the rotation of the stirring cylinder and the stirring shaft, so that the stirring cylinder and the stirring shaft are more stable during rotation, reducing shaking and deviation, ensuring the stability and reliability of the stirring process.

[0008] Further, a plurality of threaded holes are arranged at the bottom of the inner gear disc, screws are threadedly connected in the threaded holes, and the inner gear disc is fixedly connected with the stirring cylinder through the screws. The connection is firm and convenient to assemble and disassemble.

[0009] Further, the stirring blades are flexible stirring blades. The damage to the vegetables is reduced.

[0010] Further, the free ends of the stirring blades are attached to the inner wall of the stirring cylinder. During the rotation of the stirring blades, the free ends are always attached to the inner wall of the stirring cylinder, which can scrape the vegetables and auxiliary materials attached to the cylinder wall and re-roll them into the stirring area, preventing the materials from accumulating and adhering on the cylinder wall, and ensuring that all materials can participate in the stirring process. Especially when the auxiliary materials are dissolved in the liquid, the stirring blades can bring the liquid at the bottom to the upper part, which helps to improve the mixing uniformity.

[0011] Furthermore, the stirring blades are evenly distributed with liquid passage holes, which are located on the side of the stirring blades closest to the stirring shaft. When liquid additives are present, the liquid can flow through the liquid passage holes on both sides of the stirring blades, increasing the contact area and contact opportunities between the liquid and the vegetables, and promoting the penetration and diffusion of the liquid additives in the vegetables.

[0014] Figure 3 This is a schematic diagram of the structure after the stirring shaft and stirring blades are connected. Detailed Implementation

[0015] The following detailed description illustrates the specific implementation method:

[0016] The reference numerals in the accompanying drawings include: motor 1, base 2, stirring shaft 3, stirring cylinder 4, planetary gear mechanism 5, internal gear disk 51, sun gear 52, planetary gear 53, planetary carrier 54, threaded hole 55, adjusting plate 6, stirring blade 7, liquid passage hole 8.

[0017] The basic implementation examples are as follows: Figures 1 to 3 The diagram shows a stirring device comprising a base 2, a stirring drum 4, a motor 1, and a planetary gear mechanism 5. There are two bases 2, one of which has a mounting plate fixedly connected to it. The motor 1 is mounted on the mounting plate, and its output shaft is fixedly connected to a stirring shaft 3 via a coupling. The end of the stirring shaft 3 away from the motor 1 passes through the horizontally placed stirring drum 4, and the stirring shaft 3 is rotatably connected to the stirring drum 4. The stirring drum 4 has a feeding port with a door for opening and closing. The planetary gear mechanism 5 includes an internal gear disk 51, a sun gear 52, and three planetary gears 53 connected to the same planet carrier 54. The bottom of the internal gear disk 51 has six threaded holes 53. 5. A screw is threaded into the threaded hole 55. The internal gear disk 51 is fixedly connected to the end of the stirring drum 4 away from the motor 1 by the screw. The sun gear 52 is installed on the end of the stirring shaft 3 away from the motor 1 and is located inside the internal gear disk 51. Three planetary gears 53 are located between the internal gear disk 51 and the sun gear 52 and mesh with both. An adjustment disk 6 is fixedly connected to another base 2. The internal gear disk 51 and the planetary carrier 54 are rotatably connected to the adjustment disk 6. The stirring shaft 3 located inside the stirring drum 4 is provided with flexible stirring blades 7. The free end of the stirring blades 7 is in contact with the inner wall of the stirring drum 4. Liquid passage holes 8 are evenly distributed on the stirring blades 7. The liquid passage holes 8 are located on the side of the stirring blades 7 close to the stirring shaft 3.

[0018] The specific implementation process is as follows:

[0019] In use, open the hatch, put the vegetables and various accessories into the stirring cylinder 4 through the feeding port, then close the hatch to ensure that the stirring cylinder 4 forms a relatively sealed stirring space.

[0020] Then, start the motor 1, the output shaft of the motor 1 rotates to drive the stirring shaft 3 to rotate through the shaft coupling. The stirring blades 7 on the stirring shaft 3 stir and mix the vegetables and accessories in the stirring cylinder 4 as the stirring shaft 3 rotates. Since the stirring blades 7 are made of flexible material, the damage to the vegetables during stirring is reduced. At the same time, the free end of the stirring blade 7 closely adheres to the inner wall of the stirring cylinder 4, so that when the stirring blade 7 rotates, the vegetables and accessories adhering to the inner wall of the stirring cylinder 4 can be scraped off and returned to the stirring area, avoiding the accumulation and adhesion of the materials on the cylinder wall, ensuring that all materials can fully participate in the stirring process. Especially when the accessories are dissolved in the liquid, the stirring blades 7 can bring the liquid at the bottom to the upper part, which helps to improve the mixing uniformity.

[0021] At the same time, the rotation of the stirring shaft 3 also drives the sun gear 52 to rotate, which promotes the planetary gear 53 to make planetary motion around the sun gear 52, and the planet carrier 54 also rotates. The inner tooth disc 51 is fixedly connected to the stirring cylinder 4 through screws, the planet carrier 54 is rotationally connected to the adjusting disc 6, and the adjusting disc 6 is fixed to the base 2, so the rotation of the planet carrier 54 drives the stirring cylinder 4 to rotate in the opposite direction relative to the stirring shaft 3. Under the joint action of the stirring cylinder 4 and the stirring blades 7, the positions of the vegetables and accessories change constantly, effectively avoiding the uneven distribution of the vegetables and accessories in the upper and lower parts, and greatly improving the uniformity of the mixing of the vegetables and accessories.

[0022] The above is only an embodiment of the present application, and the specific structure and characteristics of the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
