Description

Technical Field

[0001] The present invention relates to the technical field of forestry seedling fertilization, and specifically provides a multifunctional fertilization device for forestry seedling raising. Background Art

[0002] Forestry seedling raising is an important basic link in forestry production and a key measure to ensure the sustainable development of forest resources and improve forest quality. Through scientific seedling raising techniques, high-quality and robust seedlings can be cultivated, providing a solid material basis for subsequent afforestation and forest management.

[0003] When raising forestry seedlings, it is necessary to fertilize the seedlings. Many existing fertilization methods are manually operated, with low fertilization efficiency. Moreover, fertilization can only be carried out unilaterally. After one side is fertilized, the other side still needs to be fertilized, and fertilization operations cannot be carried out on both sides simultaneously. During the fertilization process, spraying operations cannot be carried out simultaneously, which will greatly reduce the fertilization efficiency. In addition, the fertilizer cannot be further processed during fertilization, and the fertilizer cannot be dispersed, resulting in uneven fertilization and failing to achieve the desired fertilization effect.

A notch is provided at the top end of the active mounting rod 409, and a limiting electromagnetic block 410 is installed in the notch cavity. A magnetic sheet is installed at the top end of the inner cavity of the fixed mounting rod 401. A pulling spring 408 is sleeved on the outside of the active mounting rod 409. The top end of the pulling spring 408 is connected to the bottom end of the moving slider 411, and the bottom end of the pulling spring 408 is connected to the bottom end of the inner cavity of the fixed mounting rod 401. The bottom end of the active mounting rod 409 is connected to the top end of the material guiding frame head 602. The bottom ends of the material guiding frame heads 602 are all of an inclined structure. A connecting through port is provided at the top end of the material guiding frame head 602. The upper end of the rotating screw rod 403 is movably installed with an active nut 412. A rotating ring plate 414 is movably installed on the outside of the active nut 412. Moving rods 405 are installed on both sides of the rotating ring plate 414. One end of the moving rod 405 away from the rotating ring plate 414 is connected to the top end of the fixed mounting rod 401. Fixed notches 415 are provided on both sides of the inner cavity of the rotating ring plate 414. Fixed electromagnetic blocks 416 are installed in the fixed notches 415 through springs. A silica gel sleeve 418 is sleeved on the outside of one side of the fixed electromagnetic block 416 away from the spring. A limiting magnetic plate 417 is installed in the middle of the outer periphery of the active nut 412. The outside of the limiting magnetic plate 417 is subjected to rough treatment.

A number of balls are equidistantly installed on one side of the limiting ring strip 413 close to the active nut 412, and the balls are connected to the outside of the active nut 412;

[0035] The specific implementation method is as follows: During the fertilization process, according to the fertilization position, start the double-headed motor 407 to drive the rotating screw 403 to rotate. The rotating screw 403 drives the movable nut sleeve 412 to rotate. Due to the mutual magnetic attraction between the fixed electromagnetic block 416 and the limit magnetic plate 417, the rotating ring plate 414 will not rotate, causing the movable nut sleeve 412 and the rotating ring plate 414 to move downward, driving the fixed mounting rod 401 to move downward, and driving the material guiding frame head 602 to move downward, making the connecting hose 605 in a stretched state, so that the material guiding frame head 602 moves to the fertilization position. Then, disconnect the circuit of the fixed electromagnetic block 416, making the fixed electromagnetic block 416 lose magnetism, so that the rotating ring plate 414 loses its restraint force. When the height of the fixed plate 2 increases, disconnect the power supply of the limit electromagnetic block 410, making the limit electromagnetic block 410 lose magnetism, so that the movable mounting rod 409 loses its restraint force. Driven by the stretched pulling spring 408, the movable mounting rod 409 moves downward, further driving the material guiding frame head 602 to move downward, ensuring that after the height adjustment during movement, the material guiding frame head 602 will not be affected during fertilization. When feeding, the rotating screw 403 continues to rotate, and will not drive the rotating ring plate 414 to rotate. The rotating screw 403 drives the fan head 406 to rotate, forming an air flow inside the installation cylinder 402. The air flow inside the installation cylinder 402 is transported to the working frame 1 through the jet check valve 404. This can not only increase the air pressure inside the working frame 1 and improve the feeding efficiency, but also cool the fertilizer inside the working frame 1, avoiding the reaction of the fertilizer caused by the increase in temperature during fertilizer storage and fertilization.

Moving brush strips 607 are installed on the sides of the arc-shaped strip plates 606 far from the material guiding frame heads 602. Operating hook rods 608 are installed on the sides of the arc-shaped strip plates 606 close to the moving brush strips 607 through resilient hinges at the bottom ends. A number of convex rods are installed equidistantly around the bottom ends of the operating hook rods 608. Recovery notch openings 614 are provided around the inner cavity of the blanking through opening 613. A number of partition strips are installed on the sides of the inner cavity of the recovery notch openings 614 close to the blanking through opening 613. A filter plate 615 is movably installed between the partition strips. A blocking ring strip is installed around the bottom end of the inner cavity of the blanking through opening 613, and there is a gap between the blocking ring strip and the blanking screw rod 604.

The touch switches 617 are electrically connected to the control panel;

[0038] The specific implementation method is as follows: By rotating the screw rod 403, the rotating wheel 622 in the middle is driven to rotate. Then, through the rotating belt 623, the rotating wheels 622 on both sides are driven to rotate, and the movable rods 601 on both sides are driven to rotate, and the feeding screw rod 604 is driven to rotate inside the feeding through - port 613. The materials stored inside the working frame 1 are moved downward by the feeding screw rod 604. Then, the materials are dropped into the guiding frame head 602 through the connecting hose 605 for feeding. Since the top end of the connecting elastic cord 609 passes through the inside of the connecting hose 605 and is connected to the bottom end of the feeding screw rod 604, when the guiding frame head 602 moves downward, the connecting elastic cord 609 is in a stretched state. When the feeding screw rod 604 rotates, the connecting elastic cord 609 is driven to rotate. When the connecting elastic cord 609 rotates inside the inner cavity of the connecting hose 605, it avoids the situation of blockage in the inner cavity of the connecting hose 605 during feeding. And the connecting elastic cord 609 drives the chain belt 603 to rotate inside the guiding frame head 602. When the fertilizer drops into the guiding frame head 602, it contacts the rotating chain belt 603, and then the falling fertilizer is scattered for feeding, increasing the uniformity of the fertilizer during feeding. When the whole equipment is moved manually, the guiding frame head 602 is driven to move, and the arc - shaped strip 606 is driven to move, then the operating hook rod 608 is driven to move. Since when the guiding frame head 602 moves downward, the bottom end of the operating hook rod 608 contacts the soil in the fertilizing area. Since there are several convex rods around the bottom end of the operating hook rod 608, when the operating hook rod 608 moves, it contacts the fertilized fertilizer. When the convex rods pass by, the fertilized fertilizer is spread out, and the impurities falling in the fertilizing area are taken away by the convex rods. Through the blocking ring strip at the bottom end of the inner cavity of the feeding through - port 613, the fertilizer falling into the inner cavity of the feeding through - port 613 is temporarily blocked, so that the fertilizer stays briefly in the inner cavity of the feeding through - port 613. The rotating feeding screw rod 604 squeezes and crushes the staying fertilizer. At the same time, by squeezing the fertilizer, the excess water inside the fertilizer is removed through the filter plate 615. Then the squeezed - out water gathers in the recovery trough 614, and finally the water is collected by the collection box 616. When the fertilizer accumulated inside the feeding through - port 613 is too much, it will push the filter plate 615 to move, and drive the installation slider 620 to slide inside the installation chute 619, and squeeze the compression spring 618, so that the installation slider 620 at the top contacts the touch switch 617, disconnecting the circuit of the working electromagnet 610, making the working electromagnet 610 lose magnetism. The stretching spring in a stretched and rotating state drives the movable ejector rod 612 to move upward, and drives the feeding screw rod 604 to move upward, increasing the distance between the bottom end of the feeding screw rod 604 and the blocking ring strip, so that the accumulated fertilizer continues to fall.

[0041] The specific implementation method is as follows: the rotating block 502 is driven to rotate by the double-headed motor 407, and liquid or medicine can be added to the storage frame 505 according to the needs of seedling cultivation. When the rotating block 502 rotates, the rubber strip 503 is driven to rotate, so that the rubber strip 503 contacts and collides with the outside of the fixed installation rod 401, which causes the fixed installation rod 401 and the material guide frame head 602 to vibrate, thereby increasing the smoothness of the material feeding process. When the rotating block 502 rotates, the storage frame 505 is driven to slide inside the annular notch 501 through the fixed air pipe 507. When the storage frame 505 rotates , driving the delivery air pipe 506 and the movable cylinder 508 to rotate, so that the movable cone block 511 contacts the outer package of the rotating round block 512, pushing the movable cone block 511 to move toward the side of the movable cylinder 508, and driving the extrusion plate 510 to move, and the extrusion air bag 509 is squeezed by the extrusion plate 510, and a one-way valve is installed on the top of the delivery air pipe 506, and an air intake one-way valve is installed on one side of the extrusion air bag 509.

The front and rear sides of the middle of the bottom end of the fixed strip 301 are provided with a plurality of universal wheels. A movable strip 306 is installed, and the bottom ends of the movable strips 306 are extended inside the movable slots 307. A plurality of limit openings 305 are equidistantly opened on the opposite sides of the inner cavity of the movable slots 307 on both sides. A limit spring block 308 is installed on the side of the bottom end of the movable strip 306 close to the limit opening 305. The limit spring block 308 is connected to the inner cavity of the limit opening 305 at the bottom.

A movable support rod 304 is slidably installed at the bottom end of the stable slide rail 303, and the top end of the movable support rod 304 is connected to the bottom end of the fixed plate 2.

[0043] The specific implementation method is as follows: When the height of the seedlings is relatively high during the fertilization process, first press the limit spring block 308 to separate from the inner part of the limit through-hole 305 at the bottom, so that the moving plate 302 loses its restraint force. Then, push the fixed plate 2 upward, driving the moving plate 302 to move upward. When the limit spring block 308 moves to the corresponding position, make the limit spring block 308 fit and dock with the inner cavity of the corresponding limit through-hole 305 to fix the adjusted moving plate 302. When the fixed plate 2 moves, it drives the moving support rod 304 to slide inside the stable slide rail 303, which can not only adjust the height of fertilization according to the requirements during fertilization, but also adjust the support end during adjustment to ensure the stability during use after adjustment. Through the universal wheels, the fixed strip plate 301 and the moving plate 302 are moved to both sides of the seedlings, so that the working frame 1 and the fixed plate 2 are located directly above the seedlings.

[0044] Working principle: During the fertilization process of the present invention, according to the fertilization position, start the double-headed motor 407 to drive the rotating screw 403 to rotate. Through the rotating screw 403, drive the movable nut 412 to rotate. Due to the mutual magnetic attraction between the fixed electromagnetic block 416 and the limit magnetic plate 417, the rotating ring plate 414 will not rotate, so that the movable nut 412 and the rotating ring plate 414 move downward, driving the fixed mounting rod 401 to move downward, and driving the material guiding frame head 602 to move downward, making the connecting hose 605 in a stretched state, so that the material guiding frame head 602 moves to the fertilization position. Then, disconnect the circuit of the fixed electromagnetic block 416, so that the fixed electromagnetic block 416 loses its magnetism, and the rotating ring plate 414 loses its restraint force. When the height of the fixed plate 2 increases, disconnect the power supply of the limit electromagnetic block 410, so that the limit electromagnetic block 410 loses its magnetism, and the movable mounting rod 409 loses its restraint force. Driven by the stretched pulling spring 408, the movable mounting rod 409 moves downward, and then continues to drive the material guiding frame head 602 to move downward to ensure that after the height is adjusted during movement, the material guiding frame head 602 will not be affected during fertilization. When feeding, the rotating screw 403 continues to rotate and will not drive the rotating ring plate 414 to rotate. Through the rotating screw 403, drive the vortex fan head 406 to rotate, forming an air flow inside the installation cylinder 402. Through the jet check valve 404, the air flow inside the installation cylinder 402 is transported into the working frame 1, which can not only increase the air pressure inside the working frame 1 and improve the feeding efficiency, but also cool the fertilizer inside the working frame 1 to prevent the fertilizer from reacting due to high temperature during fertilization storage.

[0045] By rotating the screw rod 403, the rotating wheel 622 in the middle is driven to rotate. Then, the rotating belt 623 drives the rotating wheels 622 on both sides to rotate, drives the movable rods 601 on both sides to rotate, and drives the blanking screw rod 604 to rotate inside the blanking through - port 613. The materials stored inside the working frame 1 are moved downward by the blanking screw rod 604. Then, the materials are dropped into the inside of the material - guiding frame head 602 through the connecting hose 605 for blanking. Since the top end of the connecting elastic cord 609 passes through the inside of the connecting hose 605 and is connected to the bottom end of the blanking screw rod 604, when the material - guiding frame head 602 moves downward, the connecting elastic cord 609 is in a stretched state. When the blanking screw rod 604 rotates, it drives the connecting elastic cord 609 to rotate. When the connecting elastic cord 609 rotates inside the inner cavity of the connecting hose 605, it avoids the situation of blockage in the inner cavity of the connecting hose 605 during blanking, and drives the chain belt 603 to rotate inside the material - guiding frame head 602 through the connecting elastic cord 609. When the fertilizer drops into the inside of the material - guiding frame head 602, it contacts the rotating chain belt 603, and then the falling fertilizer is scattered and blanked, increasing the uniformity of the fertilizer during blanking. When the whole equipment is moved manually, it will drive the material - guiding frame head 602 to move, drive the arc - shaped strip 606 to move, and drive the operating hook rod 608 to move. Since when the material - guiding frame head 602 moves downward, the bottom end of the operating hook rod 608 contacts the soil in the fertilizing area. Since there are several convex rods around the bottom end of the operating hook rod 608, when the operating hook rod 608 moves, it contacts the fertilized fertilizer. When the convex rods pass by, they spread out the fertilized fertilizer and take away the impurities falling in the fertilizing area through the convex rods. Through the blocking ring strip at the bottom end of the inner cavity of the blanking through - port 613, the fertilizer falling into the inner cavity of the blanking through - port 613 is temporarily blocked, so that the fertilizer stays briefly in the inner cavity of the blanking through - port 613. The rotating blanking screw rod 604 squeezes and crushes the staying fertilizer. At the same time, by squeezing the fertilizer, the excess water inside the fertilizer is removed through the filter plate 615. Then, the squeezed - out water is collected into the recovery slot 614, and finally the water is collected by the collection frame 616. When the fertilizer accumulated inside the blanking through - port 613 is too much, it will push the filter plate 615 to move, drive the installation slider 620 to slide inside the installation chute 619, and squeeze the compression spring 618, so that the installation slider 620 at the top contacts the touch switch 617, disconnects the circuit of the working electromagnet 610, makes the working electromagnet 610 lose magnetism, drives the movable ejector rod 612 to move upward through the stretched and rotating tension spring, and drives the blanking screw rod 604 to move upward, increasing the distance between the bottom end of the blanking screw rod 604 and the blocking ring strip, so that the accumulated fertilizer continues to fall;
