Description

Technical Field

[0001] This utility model relates to the field of garlic screening technology, specifically a garlic size sorting machine. Background Technology

[0002] Because garlic varies in size and price, it needs to be screened in stages. Currently, there is a garlic drum screening machine on the market, and its working principle is as follows:

[0003] The drum assembly is mounted at an angle on the frame. The motor is connected to the drum assembly via a reducer, driving it to rotate around its axis. After the garlic enters the drum, the tilting and rotation of the drum cause small-diameter garlic or impurities to fall through the sieve holes, while larger-diameter garlic continues to roll, thus achieving grading and screening.

[0004] In the prior art, the drum of the garlic drum screen is a standard circular structure. During the rotation of the drum, the tumbling angle of the garlic inside the drum is small. When a large amount of material is fed at one time, some small-diameter garlic is blocked by large-diameter garlic and cannot quickly pass through the screen holes, resulting in low garlic screening efficiency. Based on this, a garlic size screening machine is provided. Utility Model Content

[0005] The purpose of this utility model is to provide a garlic size sorting machine in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a garlic size sorting machine, comprising a frame assembly having a frame body, wherein a screening assembly is provided on the inner side of the frame body, and the screening assembly is used to perform three-stage screening of garlic;

[0007] The screening assembly includes an annular turntable, a fixed rotating ring, a limiting roller, an outer screening cylinder, and an inner screening cylinder;

[0008] The outer screening cylinder is fixed to one end of the annular turntable and extends through the fixed rotating ring. The fixed rotating ring is fixedly connected to the outer side of the outer screening cylinder. The annular turntable and the fixed rotating ring are connected to the inner side of the frame body by limiting the rotation of the limiting roller.

[0009] The inner screening cylinder is distributed inside the outer screening cylinder, and one end of the inner screening cylinder is fixedly connected to the annular turntable, while the other end of the inner screening cylinder protrudes through to the outside of the outer screening cylinder.

[0010] Both the outer screening cylinder and the inner screening cylinder are provided with inwardly protruding arc-shaped parts on their inner sides, and there are multiple arc-shaped parts, which are evenly distributed along the circumferential direction.

[0011] The arc-shaped section is used to increase the overall circumferential area of ​​the outer and inner screening cylinders, thereby increasing the screening area. At the same time, two adjacent arc-shaped sections are used to form a bucket-shaped structure, which moves the garlic distributed between the two arc-shaped sections to a higher position, thereby increasing the garlic turning area.

[0012] As a further improvement of this utility model: the diameter of the screen holes on the inner screening cylinder and the outer screening cylinder decreases sequentially, and an inclined feeding plate is fixed on the inner side of the main frame body in the area below the outer screening cylinder.

[0013] As a further embodiment of this utility model: the screening assembly also includes a grid bar, a gear ring, a drive motor, and gears;

[0014] The grid bars are provided in multiple ways, and the multiple grid bars are fixed in a ring at the end of the annular turntable away from the outer screening cylinder. The toothed ring is fixed at the end of the multiple grid bars away from the annular turntable.

[0015] The drive motor is fixedly connected to the frame body via a bracket, and the gear is fixed to the output end of the drive motor and meshes with the gear ring.

[0016] As a further improvement of this utility model: the front end of the frame body is also provided with an inclined guide plate that extends from the front end of the toothed ring through the toothed ring to the middle of multiple grid bars, and the inclined guide plate is fixedly connected to the frame body by a bracket.

[0017] As a further improvement of this utility model: the arc-shaped parts of the outer screening cylinder and the inner screening cylinder are in one-to-one correspondence, and the distance between the inner side of the outer screening cylinder and the outer side of the inner screening cylinder is greater than the diameter of the garlic.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] By setting up inner and outer screening cylinders with arc-shaped sections, the garlic distributed in the middle area of ​​the two arc-shaped sections can be rotated to a higher position during the rotation of the inner and outer screening cylinders. Under its own weight, it rolls down the surface of the arc-shaped section. Compared with the traditional circular drum structure, not only is the angle of the garlic rotation larger, but the number of screen holes contacted during the rotation is also greater, thereby further improving the screening efficiency of garlic. Even when encountering a large amount of material fed at one time, it can maintain a high-efficiency screening effect. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-3 In this embodiment of the utility model, a garlic size sieving machine includes a frame assembly 1 having a frame body 101, and a sieving assembly 2 is provided on the inner side of the frame body 101. The sieving assembly 2 is used to realize the three-stage sieving operation of garlic.

[0026] The screening assembly 2 includes an annular turntable 201, a fixed rotating ring 202, a limiting roller 203, an outer screening cylinder 204, and an inner screening cylinder 205;

[0027] The outer screening cylinder 204 is fixed to one end of the annular turntable 201 and extends through the fixed rotating ring 202. The fixed rotating ring 202 is fixedly connected to the outer side of the outer screening cylinder 204. The annular turntable 201 and the fixed rotating ring 202 are connected to the inner side of the frame body 101 by limiting the rotation of the limiting roller 203.

[0028] The inner screening cylinder 205 is distributed inside the outer screening cylinder 204, and one end of the inner screening cylinder 205 is fixedly connected to the annular turntable 201, while the other end of the inner screening cylinder 205 protrudes through to the outside of the outer screening cylinder 204.

[0029] Both the outer screening cylinder 204 and the inner screening cylinder 205 have inwardly protruding arc-shaped parts on their inner sides, and there are multiple arc-shaped parts, which are evenly distributed along the circumference.

[0030] The arc-shaped section is used to increase the overall circumferential area of ​​the outer screening cylinder 204 and the inner screening cylinder 205, thereby increasing the screening area. At the same time, two adjacent arc-shaped sections are used to form a bucket-shaped structure, which moves the garlic distributed between the two arc-shaped sections to a higher position, thereby increasing the garlic turning area.

[0031] The diameter of the screen holes on the inner screening cylinder 205 and the outer screening cylinder 204 decreases sequentially. An inclined feeding plate 102 is fixed on the inner side of the frame body 101 in the area below the outer screening cylinder 204.

[0032] Screening assembly 2 also includes a grid bar 206, a toothed ring 207, a drive motor 208, and a gear 209;

[0033] Multiple grid bars 206 are provided, and the multiple grid bars 206 are fixed in a ring at one end of the annular turntable 201 away from the outer screening cylinder 204. The toothed ring 207 is fixed at one end of the multiple grid bars 206 away from the annular turntable 201.

[0034] The drive motor 208 is fixedly connected to the frame body 101 via a bracket, and the gear 209 is fixed to the output end of the drive motor 208 and meshes with the gear ring 207.

[0035] The front end of the frame body 101 is also provided with an inclined guide plate 103 that extends from the front end of the toothed ring 207 through the toothed ring 207 to the middle of multiple grid bars 206. The inclined guide plate 103 is fixedly connected to the frame body 101 through a bracket.

[0036] In this embodiment, it should be noted that the channel formed by multiple grid bars 206 is connected to the inner cavity of the inner screening cylinder 205.

[0037] The operating principle of garlic sieving is as follows:

[0038] First, start the drive motor 208. The drive motor 208 can drive the annular turntable 201, the fixed rotating ring 202, the outer screening cylinder 204, the inner screening cylinder 205 and multiple grid bars 206 to rotate as a whole through the transmission of gear 209 and gear ring 207. The limiting roller 203 provides support and limiting guidance for the rotation of the annular turntable 201 and the fixed rotating ring 202.

[0039] Then, the garlic is poured into the channel composed of multiple grid bars 206 through the inclined guide plate 103, and slides into the inner screening cylinder 205 along the channel composed of multiple grid bars 206. During this process, some impurities in the garlic can fall through the gaps in the grid bars 206.

[0040] The garlic entering the inner screening cylinder 205 rotates and flips. During this process, garlic smaller than the screen hole diameter of the inner screening cylinder 205 can pass through the screen hole and fall into the outer screening cylinder 204. This part of the garlic can rotate and flip with the outer screening cylinder 204. Among them, garlic smaller than the screen hole diameter of the outer screening cylinder 204 can pass through the screen hole and fall onto the inclined feeding plate 102. In this way, the three-stage screening of garlic is achieved.

[0041] During the above process, as the inner screening cylinder 205 and the outer screening cylinder 204 rotate, the garlic distributed in the middle area of ​​the two arc-shaped parts can be driven to flip to a higher position. Under its own weight, it will roll downward along the surface of the arc-shaped part. Compared with the traditional circular drum structure, not only is the angle of the garlic flipping area larger, but the number of screen holes contacted during the flipping process is also greater, thereby further improving the screening efficiency of garlic. Even when encountering a large amount of material fed at one time, it can maintain a high-efficiency screening effect.

[0042] Please refer to this carefully. Figures 1-3 The outer sieve cylinder 204 and the inner sieve cylinder 205 are positioned one-to-one with each other in their arc-shaped parts, and the distance between the inner side of the outer sieve cylinder 204 and the outer side of the inner sieve cylinder 205 is greater than the diameter of the garlic.

[0043] In this embodiment: This structure allows sufficient tumbling space for the garlic inside the outer screening cylinder 204, ensuring smooth secondary screening of the garlic.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
