Description

Technical Field

[0001] This invention belongs to the technical field of water conservancy machinery and equipment, specifically relating to an automatic forming device for green and ecological fish nest bricks. Background Technology

[0002] Fish nest bricks not only provide habitat and breeding space for aquatic organisms such as fish, but also increase the adhesion capacity of microorganisms on the riverbed bottom, effectively maintaining the health and diversity of aquatic ecosystems. Therefore, they are widely used in riverbank protection projects and ecological restoration projects. Currently, there are many types of fish nest bricks on the market, with different shapes, and most are single-cavity structures, suitable only for fish of a certain body length, and can only create a single flow pattern, making it difficult to guarantee habitat and spawning for different fish species. To address this, our company previously applied for a multi-cavity fish nest brick for fish habitat restoration (patent application number: 202322820156.1). This design involves creating a hollow cavity within the fish nest brick, dividing the hollow cavity into two cavities using insertable panels, with one cavity connected to the outside. The specific structure is as follows: Figure 1 As shown, this helps improve the habitat and spawning environment for fish.

[0003] However, due to the unique appearance of the fish nest bricks, current block forming equipment cannot press them into shape in one step. It requires secondary processing of the formed blocks by relevant personnel. For example, a Chinese patent discloses a block forming machine (patent announcement number: CN103737701B), which presses the raw material in the mold cavity by pressing the block, and at the same time vibrates the lower surface of the vibrating plate by the vibrator. The raw material in the mold cavity begins to form and solidify. However, objects made in this way can only be in a specific shape, so it cannot meet the current production and processing requirements of fish nest bricks.

[0004] To address this, the present invention proposes an automatic molding device for green and ecological fish nest bricks, which can realize the automated manufacturing of irregular fish nest bricks, effectively improve production efficiency, and reduce labor costs. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an automatic forming device for green and ecological fish nest bricks, so as to solve the problem that there is currently no device on the market that can produce irregular fish nest bricks.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] An automatic forming device for green ecological fish nest bricks includes a frame and a hopper and a hydraulic unit mounted on the frame. Below the hopper is a conveying unit for transferring materials. The conveying unit includes a horizontally arranged conveyor belt, a transfer tray and a forming mold mounted on the upper surface of the conveyor belt. Vertical protrusions are fixed on the upper surface of the transfer tray. The forming molds are stacked on the upper surface of the transfer tray, and the forming molds surround the protrusions and together with their surfaces form a forming chamber for containing materials. The forming chamber is transported to the lower part of the hydraulic unit by the conveyor belt.

[0008] The hydraulic unit includes a first movable support plate that moves vertically and a first hydraulic telescopic cylinder that drives the first movable support plate. A vertically placed first pressing block is fixed on the lower surface of the first movable support plate. The first pressing block cooperates with the forming chamber and together presses and forms the fish nest brick. The hydraulic unit also includes a second hydraulic telescopic cylinder for driving the forming mold to move vertically. After pressing and forming, the forming mold is detached from the transfer tray by the second hydraulic telescopic cylinder. A cutting block is mounted on the surface of the frame. The cutting block is located on the transmission path of the conveyor belt. When the fish nest brick passes the cutting block under the conveyor belt, a portion of both sides of the fish nest brick is cut off by the cutting block.

[0009] A transfer unit is installed above the conveyor belt. The transfer unit includes a support frame installed above the conveyor belt and a transfer housing movably installed on the support frame. The transfer housing moves in three-dimensional space, and a cutting frame that moves horizontally is vertically placed on the surface of the transfer housing. A driving component is provided on the transfer housing to drive the cutting frame to move. The cutting frame cuts one side surface of the fish nest brick under the drive of the driving component.

[0010] Furthermore, the bottom surface of the first pressure block is hollow and cooperates with the protrusion. Multiple vertically placed second pressure blocks are fixed on the lower surface of the first movable support plate. The number of second pressure blocks is the same as that of the first pressure blocks, and the multiple first pressure blocks and second pressure blocks are arranged alternately along the conveyor belt conveying direction.

[0011] Furthermore, a downwardly protruding insert is fixedly connected to the bottom of the first pressing block. When the bottom of the first pressing block engages with the corresponding protrusion, the insert surrounds the protrusion.

[0012] Furthermore, the top of the transfer housing is connected to a third hydraulic telescopic cylinder that drives it to move vertically. The third hydraulic telescopic cylinder is connected to a drive motor that drives it to move horizontally, and the horizontal movement direction is perpendicular to the length direction of the conveyor belt. The bottom end face of the transfer housing has a through hole communicating with its interior. After the transfer housing moves vertically along the center of the through hole, it is covered with fish nest bricks. The interior of the transfer housing and the surface of the cutting frame are provided with multiple suction cups, and each suction cup is connected to an air pump.

[0013] Furthermore, the lifting platform, conveyor belt, first hydraulic telescopic cylinder, second hydraulic telescopic cylinder, drive unit, electromagnet air pump, and third hydraulic telescopic cylinder are all electrically connected to a control unit.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention integrates the production and transportation of fish nest bricks, reducing the manual processes currently used in fish nest brick production. Furthermore, through the cooperation of the hydraulic unit and the molding chamber, the material is pressed twice, which effectively ensures that the produced fish nest bricks are uniformly compressed and of stable and reliable quality. Moreover, the use of a control unit to control various electrical devices enables the large-scale automated operation of fish nest bricks, which can effectively increase the output of fish nest bricks, reduce labor and material costs, and greatly improve work efficiency.

[0016] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0031] like Figures 1 to 11 As shown,

[0032] An automatic forming device for green ecological fish nest bricks includes a frame 1, a hopper 2 and a hydraulic unit 3 mounted on the frame 1. The hopper 2 contains raw materials for making fish nest bricks 12. Below the hopper 2 is a conveying unit 4 for transferring the materials (fish nest bricks). The conveying unit 4 includes a lifting platform 401, a horizontally arranged conveyor belt 402, a transfer tray 403 and a forming mold 404 mounted on the upper surface of the conveyor belt 402. The lifting platform 401 lifts the transfer tray 403 to the same height as the upper surface of the conveyor belt 402. The upper surface of the transfer tray 403 is fixed with multiple uniform... The evenly spaced vertical protrusions 405 are rectangular and their shape and size match the hollow cavity of the fish nest brick 12. The forming mold 404 is rectangular and runs vertically through the brick. The number and position of the forming mold 404 correspond one-to-one with the protrusions 405. The bottom of all the forming molds 404 are fixedly connected to the support plate 406. The support plate 406 is stacked on the upper surface of the transfer tray 403. The forming mold 404 surrounds the protrusions 405 and together with their surfaces, they form a forming chamber 407 for containing materials. The forming chamber 407 is transported to the bottom of the hydraulic unit 3 by the conveyor belt 402.

[0033] The conveying unit 4 also includes lead screws 408 disposed on both sides of the conveyor belt 402 and sliders 409 threadedly connected to each lead screw 408. The two lead screws 408 are rotatably disposed on the surface of the frame 1, and one end of the lead screw 408 extends to the lifting platform 401. The two lead screws 408 are connected to a drive motor (not shown in the figure) that drives them to rotate. Each lead screw 408 is threadedly connected to a slider 409 (the slider 409 is slidably connected to the surface of the conveyor belt shell, limiting the slider 409 and ensuring its movement stability). The support plate 406 is detachably connected to the two sliders 409 in the vertical direction. A vertically placed positioning block 410 is welded and fixed to the upper surface of each slider 409. The lower surface of the support plate 406 is provided with a groove that cooperates with the positioning block 410. Through the cooperation of the positioning block 410 and the groove, the slider 409 can move the support plate 406 in the horizontal plane at the same time.

[0034] The hydraulic unit 3 includes a first movable support plate 301 that moves vertically and a first hydraulic telescopic cylinder 302 that drives the first movable support plate 301. A plurality of vertically placed first pressure blocks 303 are fixed to the lower surface of the first movable support plate 301. The size and number of the first pressure blocks 303 match the forming chamber 407 and together press and form the fish nest brick 12. The hydraulic unit 3 also includes a second hydraulic telescopic cylinder 304 for driving the forming mold 404 to move vertically. The telescopic end of the second hydraulic telescopic cylinder 304 faces vertically downward and is fixed with bolts. A fixed block 5 is fixedly connected to the support plate 406. An abutment block 6, which mates with the fixed block 5, is welded to the upper surface of the support plate 406. The abutment block 6 is arranged along the length of the conveyor belt 402. The formed mold 404, after being pressed, moves vertically upward under the drive of the second hydraulic telescopic cylinder 304 and detaches from the transfer tray 403. The conveyor belt 402 then moves the transfer tray 403 and the pressed fish nest bricks 12 away from the hopper 2. A cutting block 7 is fixedly mounted on the surface of the frame 1 by bolts. The cutting block 7 is located on the transmission path of the conveyor belt 402, and its specific shape is as follows: Figure 9 As shown, when the fish nest brick 12 passes through the cutting block 7 at a constant speed under the conveyor belt 402, a portion of the two sides of the fish nest brick 12 is cut off by the cutting block 7 to form the laying groove 1203 of the fish nest brick 12.

[0035] A transfer unit 8 is mounted above the conveyor belt 402. The transfer unit 8 includes a support frame 801 mounted above the conveyor belt 402 and multiple transfer housings 802 movably mounted on the support frame 801. The size and number of the multiple transfer housings 802 correspond one-to-one with the forming mold 404. A second movable support plate 803 is bolted to the upper surface of the multiple transfer housings 802. The second movable support plate 803 drives the transfer housings 802 to move in three-dimensional space, and the surface of the transfer housings 802... A cutting frame 804 is vertically placed and moves horizontally. A spring is provided between the cutting frame 804 and the transfer housing 802, allowing it to move elastically in the horizontal direction. The transfer housing 802 is provided with a driving component that drives the cutting frame 804 to move. The driving component includes an electromagnet 805 that cooperates with the cutting frame 804. When the electromagnet 805 is energized, it attracts the cutting frame 804 and abuts against it. When the electromagnet 805 is de-energized, the cutting frame 804 moves toward the surface of the fish nest brick 12 under the action of the spring and cuts it, forming a first opening 1201.

[0036] As shown in the figure, before making the fish nest brick 12, the raw materials for making the fish nest brick 12 are first placed into the hopper 2. When it is time to make the fish nest brick 12, the two lead screws 408 rotate under the action of the drive motor and drive the slider 409 and the support plate 406 to move to the bottom of the hopper 2. The transfer tray 403 is placed on the lifting platform 401 and moves vertically upward towards the support plate 406 under its drive until the transfer tray 403 abuts against the surface of the support plate 406 (of course, there is a positioning structure between the transfer tray 403 and the support plate 406, the specific implementation method is common knowledge to those skilled in the art and will not be elaborated here). At this time, the protrusions 405 move into the forming mold 404, and the outer surface of each protrusion 405 is aligned with the corresponding forming mold. Multiple molding chambers 407 are formed by spacing between the inner walls of the mold 404. Raw materials from the hopper 2 are evenly poured into each molding chamber 407 (a vibration device is installed at the outlet end of the hopper 2 to evenly distribute the falling material into each molding chamber 407; this method is common knowledge to those skilled in the art and will not be elaborated here). After each molding chamber 407 is filled with material, the drive motor is controlled again to indirectly drive the support plate 406 and the transfer tray 403 to move together to directly below the first movable support plate 301, ensuring that the positions of the multiple first pressing blocks 303 correspond one-to-one with the multiple molding chambers 407. Subsequently, the first hydraulic telescopic cylinder 302 is activated, driving the first pressing blocks 303 to move towards the molding chambers 407, so that... The bottom end of the first pressing block 303 extrudes the raw material in the molding chamber 407, and the raw material is extruded to form a fish nest brick 12 that is hollow inside and rectangular in shape outside. After pressing and molding, the first hydraulic telescopic cylinder 302 drives the first movable support plate 301 to reset. The second hydraulic telescopic cylinder 304 drives the support plate 406 to move vertically upward through the cooperation of the fixed block 5 and the abutment block 6, so that each molding die 404 is separated from the fish nest brick 12. Then the conveyor belt 402 is started and drives the transfer pallet 403 to move towards the transfer unit 8. During the movement, the cutting block 7 cuts each fish nest brick 12 along the way and forms the laying grooves 1203 on both sides of the fish nest brick 12. When the transfer pallet 403 moves to the bottom of the second movable support plate 803, At this time, all fish nest bricks 12 have passed through the cutting block 7. Then, the second movable support plate 803 is moved so that the positions of multiple transfer shells 802 and multiple fish nest bricks 12 correspond one by one. The cutting frame 804 cooperates with one side surface of the fish nest brick 12. When the electromagnet 805 is de-energized, the spring releases elastic potential energy, causing the cutting frame 804 to move toward one side surface of the fish nest brick 12 and cut it. When the electromagnet 805 is energized again, the cutting frame 804 resets and at the same time, it will also drive the cut raw material to reset, so that the surface of the fish nest brick 12 forms the first opening 1201, completing the production of the fish nest brick 12. Afterwards, each finished fish nest brick 12 can be removed from the protrusion 405. The transfer tray 403 can be reused.When continuous production of fish nest bricks 12 is required, the drive motor is controlled to move the slider 409 and support plate 406 to directly below the hopper 2, and the empty transfer tray 403 is placed back onto the lifting platform 401. This process is repeated to achieve mass production of fish nest bricks 12, effectively improving the production of irregularly shaped fish nest bricks 12, reducing manpower and financial resources, and greatly improving work efficiency.

[0037] In this embodiment, the bottom end face of the first pressure block 303 is hollow and cooperates with the protrusion 405. The lower surface of the first movable support plate 301 is fixed with multiple vertically placed second pressure blocks 9. The number of second pressure blocks 9 is the same as that of the first pressure block 303, and the multiple first pressure blocks 303 and second pressure blocks 9 are arranged alternately along the conveyor belt 402 conveying direction.

[0038] As shown in the figure, the surface opposite the second opening 1202 on the fish nest brick 12 is closed. First, the first pressing block 303 applies pressure to the material in the forming chamber 407 for the first forming process. The resulting shape is as shown in the figure. Figure 10 As shown, the transfer tray 403 and the forming mold 404 are then indirectly driven by the drive motor to move again to the bottom of the hopper 2 for secondary material loading. After loading, they move to the bottom of the first movable support plate 301. At this time, multiple second pressing blocks 9 correspond one-to-one with multiple forming chambers 407. The first hydraulic telescopic cylinder 302 is controlled to drive the second pressing blocks 9 toward the forming chamber 407 and perform secondary extrusion of the material to form the outer wall of the fish nest brick 12. The shape after forming is as shown. Figure 11 As shown, compared to single-stage pressure molding, applying pressure to different parts of the material twice can effectively improve the compactness of the fish nest brick 12 after molding, making the pressure in each area relatively uniform, thereby ensuring the final molding quality.

[0039] In this embodiment, the bottom of the first pressing block 303 is fixedly connected with a downward protruding insert 11. When the bottom end of the first pressing block 303 engages with the corresponding protrusion 405, the insert 11 surrounds the protrusion 405.

[0040] As shown in the figure, when the first pressing block 303 moves toward the corresponding molding chamber 407 and squeezes the material inside, since the insert 11 protrudes from the bottom end face of the first pressing block 303, a slot will be left on the surface of the molded part of the fish nest brick 12 to cooperate with the insert 11. When the molding chamber 407 adds material for the second time and performs pressure molding, some material will enter the slot. When the second pressing block 9 presses the molding chamber 407, it will tightly connect the second added material with the first pressed material through the slot. Compared with the first pressing block 303 without the insert 11 at the bottom, this technique can effectively improve the connection tightness between the first pressure molding and the second pressure molding, and ensure the overall quality of the fish nest brick 12.

[0041] In this embodiment, the top of the second movable support plate 803 is connected to a third hydraulic telescopic cylinder 10 that drives it to move vertically. The third hydraulic telescopic cylinder 10 is connected to a drive motor that drives it to move horizontally. The drive motor drives the third hydraulic telescopic cylinder 10 to move through the cooperation of the lead screw 408 and the slider 409, and the horizontal movement direction is perpendicular to the length direction of the conveyor belt 402. The bottom end face of the transfer housing 802 is provided with a through hole communicating with its interior. After the transfer housing 802 moves vertically along the center of the through hole, it covers the fish nest brick 12. The interior of the transfer housing 802 and the surface of the cutting frame 804 facing the fish nest brick 12 are provided with multiple suction cups 13. Each suction cup 13 is connected to an air pump.

[0042] As shown in the diagram, when the pressed fish nest brick 12 moves to below the second movable support plate 803 under the action of the transfer tray 403 and the conveyor belt 402, the third hydraulic telescopic cylinder 10 drives the second movable support plate 803 and the transfer housing 802 to move towards the fish nest brick 12, so that each transfer housing 802 covers the corresponding fish nest brick 12. Then, the air pump is controlled to suck air from the transfer housing 802 and the multiple suction cups 13 in the cutting frame 804. The working end of the third hydraulic telescopic cylinder 10 resets and lifts each fish nest brick 12 upward. The fish nest brick 12 is separated from the transfer tray 403 and the protrusion 405. The drive motor simultaneously drives the third hydraulic telescopic cylinder 10 and the fish nest brick 12 to move horizontally and transfer the fish nest brick 12 to the next station. The air pump is controlled again to stop sucking air from the suction cups 13, and each fish nest brick 12 can be placed down. The automatic demolding and transfer of the fish nest brick 12 is achieved. Multiple suction cups 13 are used to fix the fish nest brick 12, which can effectively reduce damage to the surface of the fish nest brick 12. During the transfer process, the electromagnet 805 is de-energized, the cutting frame 804 cuts the fish nest brick 12, and the electromagnet 805 is energized again. Since the suction cups 13 in the cutting frame 804 suck air from the surface of the fish nest brick 12, the reset cutting frame 804 will simultaneously drive a part of the cut surface of the fish nest brick 12 to reset. When the suction cups 13 on the transfer housing 802 no longer hold the fish nest brick 12 and the fish nest brick 12 is detached from the transfer housing 802, the drive motor and the third hydraulic telescopic cylinder 10 are controlled to move the transfer housing 802 to another location. At this time, the suction cups 13 in the cutting frame 804 blow out air, causing the cut part of the fish nest brick 12 to detach, which is convenient for the cutting frame 804 to cut again.

[0043] While transferring the fish nest bricks 12, the surface of the fish nest bricks 12 is cut, which effectively improves work efficiency. The cut fish nest bricks 12 can be stacked in a designated area for easy collection and subsequent reuse, reducing material waste.

[0044] In this embodiment, the lifting platform 401, conveyor belt 402, first hydraulic telescopic cylinder 302, second hydraulic telescopic cylinder 304, drive component, electromagnet 805, and third hydraulic telescopic cylinder 10 are all electrically connected to a control unit (the control unit can be a PLC or a logic processing device such as an intelligent processor), thereby realizing the automated operation of the automatic molding device of the present invention, reducing manpower and material costs, and improving work efficiency.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
