Description

Technical Field

[0001] This utility model belongs to the field of fertilizer processing technology, and in particular relates to a screening device for micronutrient fertilizer processing. Background Technology

[0002] Fertilizers are substances used to improve soil fertility and promote plant growth. They contain essential nutrients for plant growth, such as nitrogen, phosphorus, and potassium. The rational use of fertilizers can increase crop yields, improve the quality of agricultural products, and contribute to the sustainable use of soil. Based on their source, fertilizers can be divided into two main categories: organic fertilizers and chemical fertilizers. Organic fertilizers, such as compost and green manure, mainly come from animal and plant residues or their metabolic products. Chemical fertilizers, on the other hand, are industrially synthesized, with clearly defined components and rapid effects. The correct selection and use of fertilizers requires comprehensive consideration of soil type, crop needs, and environmental conditions.

[0003] Micronutrient fertilizers are a type of fertilizer, and they need to be screened during processing. The problem with the above technology is that most existing fertilizer screening devices do not have the ability to roll and press the residual fertilizer on the screening screen. The clumps of fertilizer can only accumulate on the screening screen and are eventually cleaned manually, which is inconvenient. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a screening device for micronutrient fertilizer processing that can overcome or at least partially solve the above problems.

[0005] This utility model is implemented as follows: a screening device for processing trace element fertilizers includes a screening box and a screening screen. The screening screen is installed in the inner cavity of the screening box. A roller is provided on the top of the screening screen. A control rod is provided in the inner cavity of the roller. A drive assembly is provided on the front side of the control rod. A connecting block is fixedly connected to the rear side of the control rod. A locking assembly is provided on the rear side of the connecting block. A placement hole is opened on the front side of the screening box. A collection box is provided in the inner cavity of the placement hole.

[0006] The drive assembly is used for controlling the rolls;

[0007] The locking assembly is used to fix the position of the roll.

[0008] To control the rollers, preferably, the drive assembly includes a slide plate with a slider fitted on its surface. A drive block is fixedly connected to one side of the slider, and a motor is provided on one side of the drive block. A threaded rod is installed at the output end of the motor, and one side of the threaded rod passes through the drive block and extends to the outside of the drive block. The drive assembly can control the movement of the rollers, thereby pressing the fertilizer that has agglomerated on the screening screen.

[0009] To fix and limit the position of the roll, preferably, the locking assembly includes a locking block, with limit blocks provided at the top and bottom of the locking block, and limit holes provided on the surface of the limit blocks, with limit rods provided in the inner cavity of the limit holes, so as to limit the roll when it is not in use.

[0010] In order to crush the fertilizer residue on the screening screen, preferably, the bottom of the roller contacts the screening screen, and one side of the collection box contacts the inner wall of the screening box. The roller can crush the fertilizer residue that has clumped on the screening screen.

[0011] In order to control the rollers, preferably, the front side of the control rod is fixedly connected to the slider, the side of the slider near the surface of the slide plate is in contact with the surface of the slide plate, the rear side of the slide plate is fixedly connected to the screening box, and the drive assembly can control the movement of the rollers to roll the fertilizer that has agglomerated on the screening screen.

[0012] In order to control the rollers, preferably, a support frame is fixedly connected to one side of the motor, and a mounting plate is fixedly connected to one side of the support frame. The mounting plate is fixedly connected to the screening box by bolts. The drive assembly can control the movement of the rollers, thereby rolling the fertilizer that has agglomerated on the screening screen.

[0013] In order to fix and limit the position of the roll, preferably, the front side of the locking block is fixedly connected to the connecting block, the front side of the limiting block is fixedly connected to the surface of the screening box, and the front side of the limiting rod passes through the limiting hole and extends into the inner cavity of the locking block, so as to limit the roll when the roll is not in use.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention solves the problem that most existing fertilizer screening devices lack the ability to press residual fertilizer on the screening screen, resulting in clumps of fertilizer accumulating on the screen and requiring inconvenient manual cleaning. The invention utilizes a combination of a motor, a threaded rod, a drive block, a slider, a slide plate, a control rod, and a roller. When the motor is started, it drives the threaded rod to rotate within the drive block. The drive block moves in the direction of the threaded rod's rotation, causing the slider to slide on the surface of the slide plate. The slider then moves the control rod, which in turn moves the pressure roller to press the fertilizer onto the surface of the screening screen. Attached Figure Description

[0024] The working principle of this utility model:

[0025] In use, the user pulls the limiting rod 704 outward, disengaging it from the inner cavity of the limiting hole 703 and the limiting block 702. Then, the user starts the motor 504, which drives the threaded rod 505 to rotate. The threaded rod 505 rotates within the inner cavity of the drive block 503, and the drive block 503 moves according to the rotation direction of the threaded rod 505. The drive block 503 drives the slider 502 to slide on the surface of the slide plate 501, which in turn drives the control rod 4 to move. The control rod 4 drives the pressure roller to roll the fertilizer on the surface of the screening screen 2. The control rod 4 also drives the locking block 701 to slide on the surface of the limiting block 702. When it is no longer necessary to roll the fertilizer, the user turns off the motor 504 and resets the limiting rod 704 to complete the limiting operation.
