Description

Technical Field

[0001] This utility model relates to the field of fritillaria screening technology, and in particular to a fritillaria grading and screening device. Background Technology

[0002] Fritillaria is a general term for perennial herbaceous plants belonging to the genus Fritillaria in the family Liliaceae. The bulb is deeply buried in the soil, covered by a bulb skin. The stem is erect and unbranched, with basal leaves having long petioles; the stem leaves are opposite, whorled, or scattered. Fritillaria varies in size depending on its growth, and the market price differs significantly between different sizes, so screening and classification based on size are often necessary.

[0003] According to utility model patent CN222241208U, a screening device for Fritillaria cirrhosa includes a mounting frame with two outer support rings fixedly connected to its outer surface. Each outer support ring has a retaining ring fixedly connected to its inner wall. Through the coordinated action of a screen, an inclined lifting plate, and a non-inclined lifting plate, when the Fritillaria cirrhosa material enters the screen through the lifting device body, the rotation of the screen drives the inclined and non-inclined lifting plates to rotate. The inclined lifting plate, driven by the screen, guides the flow of the Fritillaria cirrhosa material during screening. While guiding the movement of the Fritillaria cirrhosa, the pore size of both plates also screens it, increasing screening efficiency. Furthermore, the smaller pore size reduces the flow velocity of the Fritillaria cirrhosa, thus reducing the impact force and breakage rate during screening.

[0004] Although the above technical solution can achieve the screening of fritillaria, it still uses the principle of roller screening. Furthermore, the operation of setting up lifting plates inside the screen does not reduce the collision force of fritillaria screening. In addition, the device cannot achieve graded screening of fritillaria when screening. Utility Model Content

[0005] The purpose of this invention is to provide a fritillaria grading and screening device that can screen fritillaria, and can not only improve the screening effect of fritillaria but also grade it.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A fritillaria cirrhosa grading and screening device includes a fixed base frame. Fixed rods are arranged opposite each other on the left and right sides of the upper front end of the fixed base frame, and electric push rods are installed opposite each other on the left and right sides of the upper rear end of the fixed base frame. A support frame is rotatably connected to the upper ends of the fixed rods and the electric push rods. The front end of the bottom of the support frame is rotatably connected to the fixed rods. A rotating component is fitted between the upper end of each electric push rod and the bottom of the support frame. A screening component is rotatably connected between the left and right sides of the upper inner wall of the support frame. A conveying hopper extending above the screening component is inclined downwards from the rear end of the upper end of the support frame. A receiving component for receiving fritillaria cirrhosa is provided at the front end of the outer wall of the support frame, cooperating with the screening component. A driving component for driving the screening component to swing back and forth is provided at the rear end of the inner wall of the support frame. A control panel is provided at the rear end of the outer wall of the support frame. The electric push rods and the driving component are electrically connected to the control panel.

[0007] By adopting the above technical solution, when using the device, first move it to the corresponding position and fix the base frame. Then, power on the device and operate the control panel to control the electric push rod to tilt the connecting frame forward at a certain angle. Then, the drive component will work and drive the screening component to shake back and forth. Next, the operator pours the fritillaria that needs to be screened into the screening component through the feed hopper for screening. The fritillaria in the screening component will be received and transported by the receiving component and then collected. During the screening process, the operator can control the tilt angle of the connecting frame according to the screening effect and the uniformity of the fritillaria fruit in the current batch. By increasing the residence time of the fritillaria on the screening component, the screening effect can be improved.

[0008] A further feature of this invention is that the rotating assembly includes a U-shaped fixed base, a rotating shaft rotatably connected to the left and right sides of the inner wall of the fixed base, and a connecting base disposed on the outer wall of the rotating shaft and extending out of the upper end of the fixed base.

[0009] By adopting the above technical solution, the electric actuator can easily adjust the angle of the connecting frame through the rotating assembly.

[0010] The present invention is further configured as follows: the screening component includes a U-shaped fixed frame, a plurality of screens arranged from bottom to top between the left and right sides of the inner wall of the fixed frame and distributed at equal intervals, and rocker arms rotatably connected to the front and rear ends of the upper left and right sides of the outer wall of the fixed frame, wherein the diameter of the screen holes of the screens in the fixed frame increases sequentially from bottom to top.

[0011] A further feature of this invention is that the receiving assembly includes a U-shaped connecting frame and a plurality of receiving hoppers arranged along the height direction of the connecting frame and inclined downward from back to front. The length of each receiving hopper decreases sequentially from top to bottom along the height direction of the connecting frame, and the rear end of each receiving hopper extends to the bottom of the front end of the corresponding screen.

[0012] By adopting the above technical solution, staff can easily collect the screened fritillaria bulbs by grade, avoiding confusion.

[0013] A further feature of this invention is that the driving assembly includes a driving motor, a driving disk disposed on the outer wall of the power output shaft of the driving motor, and a rocker arm rotatably connected to the eccentric position of the driving disk. The front end of the rocker arm is connected by a rotating buckle disposed on the rear end of the outer wall of the screening assembly.

[0014] A further feature of this invention is that a protective cover for covering the drive motor is provided at the rear end of the outer wall of the support frame, and the control panel is located above the rear end of the outer wall of the protective cover.

[0015] By adopting the above technical solution, contact between workers and the drive motor can be avoided when workers add fritillaria bulbs for sieving, thus reducing safety hazards.

[0016] In summary, this utility model has the following beneficial effects: Firstly, this utility model can screen fritillaria bulbs, and during the screening process, it can not only improve the screening effect of fritillaria bulbs but also perform graded screening. Secondly, the electric push rod and rotating assembly of this utility model can adjust the tilt angle of the connecting frame according to the actual situation, thereby extending or shortening the residence time of the fritillaria on the screen, thus improving the grading and screening effect of the fritillaria. Thirdly, the upright of this utility model can not only provide fixed support for the support frame, but also improve the stability of the support frame while the electric push rod adjusts its tilt angle.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., 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, and 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. Therefore, they should not be construed as limitations on this utility model.

[0021] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but can be slightly tilted.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Example, refer to Figure 1-4 A fritillaria grading and screening device includes a fixed base frame 1. A fixed rod 11 is arranged opposite to the left and right sides of the upper front end of the fixed base frame 1. An electric push rod 12 is installed opposite to the left and right sides of the upper rear end of the fixed base frame 1. A support frame 2 is rotatably connected to the upper end of the fixed rod 11 and the electric push rod 12. The front end of the bottom of the support frame 2 is rotatably connected to the fixed rod 11. A rotating component 13 is arranged between the upper end of each electric push rod 12 and the bottom of the support frame 2. The rotating component 13 includes a U-shaped fixed seat 14, a rotating shaft 15 rotatably connected to the left and right sides of the inner wall of the fixed seat 14, and a connecting seat 16 arranged on the outer wall of the rotating shaft 15 and extending out of the upper end of the fixed seat 14.

[0024] A screening component 21 is rotatably connected between the left and right sides of the upper inner wall of the support frame 2. The screening component 21 includes a U-shaped fixed frame 22, four screens 23 arranged from bottom to top between the left and right sides of the inner wall of the fixed frame 22 and evenly distributed, and four rocker arms 24 rotatably connected to the front and rear ends of the left and right sides of the upper outer wall of the fixed frame 22. The diameter of the screen holes of the screens 23 in the fixed frame 22 increases from bottom to top. A feeding hopper 25 extending above the rear end of the fixed frame 22 is provided at the rear end of the upper end of the support frame 2. A receiving component 3 is provided at the front end of the outer wall of the support frame 2, which cooperates with the screening component 21 and is used to receive the fritillaria. The receiving component 3 includes a U-shaped connecting frame 31 and four receiving hoppers 32 arranged along the height direction of the connecting frame 31 and all arranged from back to front and downward, corresponding to the screens 23. When the screening component 21 is working, the receiving component 3 will not contact the fixed frame 22 and the screens 23.

[0025] The length of each receiving hopper 32 decreases from top to bottom along the height direction of the connecting frame 31. The rear end of each receiving hopper 32 extends below the front end of the corresponding screen 23. A drive assembly 4 for driving the screening component 21 to swing back and forth is provided at the rear end of the support frame 2. The drive assembly 4 includes a drive motor 41, a drive disk 42 set on the outer wall of the power output shaft of the drive motor 41, and a rocker arm 43 rotatably connected to the eccentric position of the drive disk 42. The front end of the rocker arm 43 is connected by a rotating buckle 44 set on the rear end of the outer wall of the fixed frame 22. A protective cover 45 for covering the drive motor 41 is provided at the rear end of the outer wall of the support frame 2. A control panel 46 is provided above the rear end of the outer wall of the protective cover 45. The electric push rod 12 and the drive assembly 4 are electrically connected to the control panel 46.

[0026] Usage: When using, first move the device to the corresponding position and fix the base frame 1. Then, power on the device and operate the control panel 46 to control the electric push rod 12 to work. The connecting frame 31 is tilted forward at a certain angle by the rotating component 13. When the length of the electric push rod 12 changes, the fixed seat 14 will rotate the connecting seat 16 at a certain angle through the rotating shaft 15, thereby realizing the rotation of the support frame 2. When the support frame 2 rotates, although the length of the fixed rod 11 remains unchanged, it will not affect the normal rotation of the support frame 2. At the same time, it can also improve its stability to a certain extent. Then, let the drive component 4 work. The drive motor 41 drives the drive disk 42 to rotate. At the same time, the rocker arm 24 drives the fixed frame 22 to sway back and forth through the cooperation of the rocker arm 43 and the rotating buckle 44. Then, the operator pours the pearl powder to be screened into the screening component 21 through the feeding hopper 25 for screening.

[0027] The fritillaria bulbs entering the screening component 21 will fall from top to bottom onto the screens 23 with corresponding screen hole diameters as the fixed frame 22 shakes back and forth. The fritillaria bulbs left on the corresponding screen 23 will move forward along the screen 23 and fall onto the corresponding receiving hopper 32 of the receiving component 3, where they can be collected by the staff. Since the lengths of the receiving hoppers 32 are different, the screened fritillaria bulbs will not be mixed up. During the screening process, the staff can control the tilt angle of the connecting frame 31 according to the screening effect and the uniformity of the fritillaria bulb fruits in the current batch. By increasing the residence time of the fritillaria bulbs on the screening component 21, the screening effect can be improved. When the fixed frame 22 shakes, the lower end of the conveying hopper 25 and the upper end of each receiving hopper 32 on the connecting frame 31 will not contact the fixed frame 22, but this will not affect the normal conveying and receiving work.

[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that make creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
