Description

Technical Field

[0001] This utility model relates to the field of seedling conveying screen technology, and more specifically, to a seedling conveying screen assembly. Background Technology

[0002] Pneumatic grain separators are commonly used in grain processing, seed treatment, and other fields, primarily for removing impurities and improving product purity. The seed conveying screen is a crucial component, responsible for separating raw materials into particles of different sizes through the screen mesh. However, in practical use, it still has some drawbacks. For example, during the screening process, large-volume raw materials tend to remain on the screen, and excessive accumulation can clog some of the screen openings, preventing smaller materials from passing through and thus affecting screening efficiency.

[0003] Therefore, a seedling conveying screen assembly was proposed to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a seedling conveying screen assembly to solve the problem that in the prior art seedling conveying screen, large-volume raw materials will remain on the screen during the screening process, and when too much material is accumulated, it will block some of the screen holes, thus preventing small-volume materials from falling.

[0005] To solve the above technical problems, this utility model provides the following technical solution: a seedling conveying screen assembly, including a base plate, a connecting frame provided on the top of the base plate, a screening component installed inside the connecting frame, and a vibration component fixedly installed on the top of the base plate;

[0006] The vibration assembly includes a support frame, a slider is slidably connected inside the support frame, a first spring is fixedly connected to the top and bottom of the slider, the end of the first spring away from the slider is fixedly connected to the inside of the support frame, one side of the slider is fixedly connected to the side of a connecting frame, a connecting block is fixedly connected to the other side of the slider, a motor is fixedly mounted on one side of the connecting block, a rotating shaft is fixedly connected to the output end of the motor, the outer surface of the rotating shaft is rotatably connected to the inside of the connecting block, and a semi-circular block is fixedly mounted on the end of the rotating shaft away from the motor.

[0007] The screening assembly includes a frame and a screen body. The outer surface of the frame is detachably connected to the interior of the connecting frame. Mounting holes are provided on both sides of the frame, and the screen body is fixedly installed inside the frame.

[0008] It also includes support bars, which are fixedly installed on the bottom of the base plate to support the screening assembly.

[0009] It also includes a disassembly assembly, with the vibration assembly located on both sides of the connecting frame.

[0010] The detachable assembly includes a base, a button, a wedge block, a plug rod, a diagonal rod, and a second spring. One side of the base is fixedly connected to the side of the connecting frame. The outer surface of the button is slidably connected to the interior of the base. The wedge block is fixedly installed inside the button. The outer surface of the plug rod is slidably connected to one side of the base. The outer surface of the diagonal rod is slidably connected to the interior of the plug rod. Both ends of the diagonal rod are slidably connected to the outer surface of the wedge block. One end of the second spring is fixedly connected to one end of the plug rod, and the other end of the second spring is fixedly connected to the interior of the button.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0012] In the above scheme, a base plate, connecting frame, screening component, and vibration component are set up. When the motor is started, the motor drives the semi-circular block to rotate through the rotating shaft, thereby generating vibration. This causes the slider to slide up and down in the support frame. Under the action of the elastic force of the first spring, the slider drives the connecting frame to vibrate. Through the above structure, the screening component is in a vibrating state during screening, causing the material on the screening component to tumble slightly, effectively preventing large-volume materials from clogging the screen holes and thus affecting normal feeding.

[0013] The easy-to-disassemble component is installed. Pressing the button into the base moves the wedge block, causing the inclined rod to slide in the insert rod, which then slides inward toward the button, disengaging the insert rod from the mounting hole. At this point, the second spring is in a contracted state. After replacing the screening component, releasing the button allows the insert rod to re-insert into the mounting hole under the rebound force of the second spring, completing the fixation. With this structure, the screening component can be replaced without the need for disassembly tools. Different models of screening components can be replaced as needed, greatly improving disassembly and assembly efficiency. Attached Figure Description

[0027] The screening component 3 includes a frame 31 and a screen body 33. The outer surface of the frame 31 is detachably connected to the interior of the connecting frame 2. Mounting holes 32 are provided on both sides of the frame 31, and the screen body 33 is fixedly installed inside the frame 31.

[0028] It also includes a support bar 11, which is fixedly installed at the bottom of the base plate 1 to support the screening assembly 3.

[0029] It also includes a disassembly assembly 5 and a vibration assembly 4 on both sides of the connecting frame 2.

[0030] The detachable component 5 includes a base 51, a button 52, a wedge block 53, a rod 54, a diagonal rod 55, and a second spring 56. One side of the base 51 is fixedly connected to the side of the connecting frame 2. The outer surface of the button 52 is slidably connected to the inside of the base 51. The wedge block 53 is fixedly installed inside the button 52. The outer surface of the rod 54 is slidably connected to one side of the base 51. The outer surface of the diagonal rod 55 is slidably connected to the inside of the rod 54. Both ends of the diagonal rod 55 are slidably connected to the outer surface of the wedge block 53. One end of the second spring 56 is fixedly connected to one end of the rod 54, and the other end of the second spring 56 is fixedly connected to the inside of the button 52.

[0031] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0032] In the above scheme, a base plate 1, a connecting frame 2, a screening component 3, and a vibration component 4 are set up. The motor 45 is started, and the motor 45 drives the semi-circular block 47 to rotate through the rotating shaft 46, thereby generating vibration. This causes the slider 42 to slide up and down in the support frame 41. Under the elastic force of the first spring 43, the slider 42 drives the connecting frame 2 to vibrate. Through the above structure, the screening component 3 is in a vibrating state during screening, causing the material on the screening component 3 to tumble slightly, effectively preventing large-volume materials from clogging the screen holes and affecting normal feeding.

[0033] The easy-to-disassemble component 5 is installed. Pressing button 52 into base 51 moves wedge block 53, causing inclined rod 55 to slide in insertion rod 54, making insertion rod 54 slide inward towards button 52, thus disengaging insertion rod 54 from mounting hole 32. At this time, spring 56 is in a contracted state. After replacing screening component 3, release button 52. Under the rebound force of spring 56, insertion rod 54 will insert into mounting hole 32 to complete the fixation. With the above structure, screening component 3 can be replaced without the need for disassembly tools. Different models of screening component 3 can be replaced as needed, greatly improving disassembly and assembly efficiency.

[0034] The semicircular block 47 has an uneven center of gravity distribution, which causes it to wobble when rotating around the center. The two ends of the inclined rod 55 are set as inclined surfaces, which fit the surface shape of the wedge block 53 and can be pushed by the wedge block 53.

[0035] The working process of this utility model is as follows: Start the motor 45. The motor 45 drives the semi-circular block 47 to rotate through the rotating shaft 46, thereby generating vibration, causing the slider 42 to slide up and down in the support frame 41. Under the elastic force of the first spring 43, the slider 42 drives the connecting frame 2 to vibrate.

[0036] Press button 52 into base 51 to move wedge block 53, causing inclined rod 55 to slide in insert rod 54, causing insert rod 54 to slide inward toward button 52, thereby disengaging insert rod 54 from mounting hole 32. At this time, spring 56 is in a contracted state. After replacing screening component 3, release button 52. Under the rebound force of spring 56, insert rod 54 will be inserted into mounting hole 32, completing the fixation.
