Description

Technical Field

[0001] This utility model relates to the technical field, specifically a multi-stage garlic sorting machine. Background Technology

[0002] Garlic, a common seasoning in daily life, has the effects of detoxifying and cleansing the intestines, sterilizing and disinfecting, and is also very nutritious. Due to the different sizes and prices of garlic, it is necessary to grade and screen garlic, which requires the use of a multi-stage garlic sorting machine. Before selling garlic, farmers need to dry it and peel off the outermost layer of garlic skin with soil on it. During the drying process, the garlic is exposed to the sun, causing the outer skin to break easily. As a result, when the garlic is sorted in the sorting machine, it rubs against the inner wall of the drum-type sorting screen, causing a large amount of garlic skin to fall off.

[0003] A garlic sorting machine, as disclosed in CN216779461U, includes a drum-type sorting screen connected to a support frame. The drum-type sorting screen is connected to a drive structure that rotates it. The drum-type sorting screen is divided into multiple stages, each with different screen openings. Each stage has a discharge port at its bottom, and a feeding structure is connected to its front end. This application uses a drum-type sorting screen to sort garlic. The rotation of the drum-type sorting screen achieves a stirring effect on the garlic entering the screen, not only driving the garlic forward but also improving sorting efficiency. Furthermore, dividing the drum-type sorting screen into multiple stages allows for the separation of garlic with better uniformity, thus improving the uniformity of the garlic after sorting. In addition, existing sorting machines have the following disadvantages in use:

[0004] (1) The existing sorting machine does not have a cleaning structure, which makes it easy for the large garlic peels to block the screen holes, thus preventing the small garlic from passing through the screen. This results in poor screening quality and requires manual secondary screening, increasing the workload of the staff and reducing the sorting efficiency of the sorting machine.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a multi-stage garlic sorting machine.

[0007] To solve the above problems, the technical solution of this utility model is as follows: a base and a support frame fixedly connected to its top. A roller sorting screen is installed inside the support frame. The roller sorting screen is divided into multiple levels. Each level of the roller sorting screen 3 has an inclined plate at its bottom. A baffle is fixedly connected to one side of several inclined plates, and an inclined guide plate is symmetrically fixedly connected to the other side. A cleaning structure is installed inside the roller sorting screen. The top of the support frame is provided with a driving structure that drives the roller sorting screen and the cleaning structure to rotate in different directions. A number of equidistant circular screen holes are opened on the outer wall of each level of the roller sorting screen. The diameter of the screen holes of each level of the roller sorting screen increases sequentially from front to back.

[0008] Furthermore, a blower is fixedly connected to the front side of the base, and an air supply pipe is inserted into the air outlet of the blower. The rear end of the air supply pipe passes through the support frame and extends into the interior of the drum-type sorting screen. An air inlet is opened on the side of the blower away from the guide plate.

One end of the drive shaft is connected to a support frame by a bearing, and the other end passes through a drum-type sorting screen and a fixed plate in sequence, and is fitted with a synchronous drive wheel. Helical teeth are wound around the outside of the drive shaft. The drive shaft and the helical teeth are connected by several equidistant connecting rods. A cleaning brush is fixedly connected to the outer wall of the helical teeth. The side of the cleaning brush away from the drive shaft abuts against the inner wall of the drum-type sorting screen.

[0010] Furthermore, the bottom sides of several of the gears pass through the relief grooves and mesh with the gear ring for transmission, and the first synchronous transmission wheel and the second synchronous transmission wheel are connected by a synchronous transmission belt.

[0011] Furthermore, a support plate is fixedly connected to the top front side of the support frame, a feeding funnel is fixedly connected to the top of the support plate, a feeding pipe is provided at the bottom of the feeding funnel, one end of the feeding pipe is fixedly connected to the feeding funnel, and the other end passes through the support frame and extends into the interior of the drum-type sorting screen.

[0012] Furthermore, the outer wall of the drum-type sorting screen is fitted with several equidistant toothed rings, the top of the support frame is provided with several equidistant relief grooves corresponding to the toothed rings, the top of the support frame is fixedly connected with several equidistant fixed seats, the rear side of the support frame is provided with a through hole, the rear part of the through hole is fixedly connected with a fixed plate, one end of the drum-type sorting screen is connected to the support frame by a bearing, and the other end is connected to the inner wall of the through hole by a bearing.

[0013] Furthermore, the drive structure includes a drive shaft, one end of which is fixedly connected to a drive motor, and the other end of which passes through a fixed seat and is fitted with a synchronous transmission wheel. Several equidistant gears are fitted onto the outer wall of the drive shaft.

[0014] The advantages of this invention compared to existing technologies are as follows:

[0015] 1. This utility model provides a multi-stage garlic sorting machine. The spiral teeth are fixed to the drive shaft by the connecting rod and rotate in the opposite direction to the drum-type sorting screen. The cleaning brush is in close contact with the inner wall of the screen hole and continuously scrapes. The blower sends air into the drum through the air pipe. The wind helps to blow away the garlic skin. The physical scraping of the cleaning brush combined with the wind sweeping provides double cleaning of the screen hole, which completely avoids garlic skin residue and ensures that small-sized garlic can pass through the screen smoothly. The automated cleaning process reduces the frequency of manual cleaning. Attached Figure Description
