The silo is large and the discharge port is small, which is easy to cause material stacking and blocking. Some are also equipped with arch breaking devices. The unloading speed depends on the structural rationality and installation position of the arch breaking device. If the hopper opening is large, it cannot be unloaded quickly and the waiting time is long. Summary of the invention

[0012] A plurality of rotating shafts are evenly and uniformly mounted on the movable frame, and the arrangement direction of each of the rotating shafts is the same as the arrangement direction of the supporting rods;

[0013] Multiple seesaws are plate-type structures with multiple air holes. One side of the seesaws is installed on each of the rotating shafts and can rotate along the rotating shafts, and the other side is placed on the top of the support rods. They are used to change the supporting positions of the seesaws and the corresponding support rods when the movable frame reciprocates, so that the seesaws can change between horizontal and inclined angles, thereby realizing unloading or not.

[0014] Furthermore, it also includes:

[0015] A factory building, arranged outside the unloading system, providing a closed unloading environment;

[0016] At least one suction hood is arranged on the top of the factory building, above the container, and is used to absorb dust generated during the unloading process; the suction hood is connected with a suction pipeline, a negative pressure fan and a dust removal device in sequence.

[0017] Furthermore, the bottom of the container is installed above the maintenance steel platform.

[0018] The second technical solution adopted by the present invention is a method for using a container-type seesaw micro-negative pressure unloading device, characterized in that one or more sections of the unloading plate are selectively opened according to the length of the transport vehicle, and the material moves downward for unloading;

[0019] The hydraulic rod of the hydraulic cylinder extends to drive the movable frame, the rotating shaft and the seesaw to move together.

DETAILED DESCRIPTION

[0028] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 1 and Figure 2 As shown, the present invention provides a container-type seesaw micro-negative pressure unloading device, which in some embodiments includes: a container 1, a material distribution belt conveyor 4 and at least one unloading plate 7.

[0030] The top of the container 1 is open as a material feed port, and the material is usually an organic fertilizer material. The material distribution belt conveyor 4 is arranged above the container 1, and is used to transport materials into the container 1. The material distribution belt conveyor 4 may include a feeding belt conveyor 41 and a material distribution trolley 42. The material distribution trolley 42 has its own power and will move the material distribution position on the main belt frame. The feeding belt conveyor 41 delivers the material to the belt of the material distribution trolley 42, and the belt of the material distribution trolley 42 (with its own drive motor) moves to deliver the material to the silo of the container 1.

[0031] Since the container 1 is long, a plurality of unloading plates 7 can be arranged in parallel at the bottom of the container 1 to facilitate the unloading of materials in the container 1 in different areas. The area of ​​the unloading plate 7 is substantially the same as the bottom area of ​​the container 1, so during the unloading process, the unloading outlet area is large, the unloading speed is fast, and it is not easy to be blocked.

[0032] The container-type seesaw micro-negative pressure unloading device of the present invention uses a standard container 1 as a material carrier, and does not have a top as a feed port. The material distribution belt conveyor 4 is usually arranged and a material distribution trolley 42 is used to evenly distribute the material into the container 1. A discharge plate 7 is set at the bottom of the container 1 to drag the material. Generally speaking, the length of the container 1 is relatively long, and it can be divided into multiple sections and multiple discharge plates 7 can be installed. For example, the entire container 1 is 12m long, and the container 1 can be divided into three sections for independent and simultaneous unloading. The three sections are three frames at the bottom of the container 1, and the three discharge plates 7 are respectively installed in the three frames.

[0033] like Figure 3-4As shown, the unloading plate 7 includes a track 71, which is a rectangular frame and is fixed in position; a plurality of support rods 75, which are evenly and fixedly mounted on the track 71; a movable frame 72, which is a rectangular frame, is mounted on the track 71, and one side of which is connected to a hydraulic cylinder 12, which is used to reciprocate along the track under the action of the hydraulic cylinder 12; a plurality of rotating shafts 73, which are evenly and mounted on the movable frame 72, and the arrangement direction of each of the rotating shafts 73 is the same as the arrangement direction of the support rods 75; a plurality of seesaws 74, which are plate structures, are provided with a plurality of air holes, one side of which is mounted on each of the rotating shafts 73 and can rotate along the rotating shafts 73, and the other side is placed on the top of the support rods 75; it is used to change the supporting position of the seesaw 74 and the corresponding support rods 75 when the movable frame 72 reciprocates, so that the seesaw 74 changes between the horizontal and inclined angles, thereby realizing unloading or not.

[0034] The seesaw 74 is connected to the rotating shaft 73 in rotation, and the rotating shaft 73 is connected to the movable frame 72 and can drive the seesaw 74 to rotate; the hydraulic cylinder 12 pushes the movable frame 72, and the movable frame 72 drives the rotating shaft 73 and the seesaw 74 to move forward. When the seesaw 74 moves forward, the supporting arm becomes smaller and smaller, and the seesaw 74 moves downward under the action of gravity until the hydraulic cylinder 12 is fully extended, and the seesaw 74 will also move downward to the maximum opening, and the material falling opening will also be the largest. When closing, the hydraulic cylinder 12 moves backward, the movable frame 72 moves backward, and the supporting arm of the seesaw 74 becomes larger and larger, until the cylinder rod is fully retracted until it is completely closed.

[0035] like Figure 1 and Figure 2 As shown, the container-type seesaw micro-negative pressure unloading device also includes a factory building and an exhaust system. The factory building is arranged outside the unloading system to provide a closed unloading environment. The exhaust system includes an air suction hood 5, which is arranged on the top of the factory building, above the container 1, and is used to absorb dust generated during the unloading process; the air suction hood 5 is connected to an air suction pipeline 8, a negative pressure fan 9 and a dust removal device 10 in sequence.

[0036] A set of exhaust system outside the unloading plant 11 includes an air suction hood 5 on the top of the unloading container. The negative pressure exhaust system has been turned on before unloading. A large amount of dust will be generated during the unloading process. Under the suction force of the negative pressure fan, the dust will gather in the direction of the air collection hood and be sucked into the dust removal equipment. The dust is collected and filtered, and the air is discharged outdoors. The exhaust system removes the dust generated during the loading process, improves the on-site working environment, and reduces pollution to the environment. Figure 1 and Figure 2 As shown, the bottom of the container 1 is installed above the maintenance steel platform 2 to facilitate maintenance of the equipment.

[0037] The present invention also provides a method for using a container-type seesaw micro-negative pressure unloading device, in which one or more unloading plates 7 are selectively opened according to the length of the transport vehicle 6, and the materials continuously move downward under the effect of losing gravity and are loaded into the transport vehicle 6. When the vehicle is about to be full, the hydraulic rod of the hydraulic cylinder 12 is controlled to be retracted, and the unloading plate 7 is closed to complete the unloading work.

[0038] The hydraulic rod of the hydraulic cylinder 12 extends, driving the movable frame 72, the rotating shaft 73 and the seesaw 74 to move together, wherein the seesaw 74 is separated from the support of the corresponding support rod 75 during the movement, and rotates downward, so that the unloading plate 7 opens downward. The hydraulic rod of the hydraulic cylinder 12 is retracted, driving the movable frame 72, the rotating shaft 73 and the seesaw 74 to move in the opposite direction, wherein the seesaw 74 is supported by the corresponding support rod 75 in a horizontal position during the movement, so that the unloading plate 7 is closed.

[0039] In some embodiments, after the transport vehicle 6 enters different designated areas according to its length, the front and rear doors of the plant 11 will automatically close and trigger the photoelectric sensor set at the door. The photoelectric sensor will give a signal to the controller, and the controller will delay for a period of time, such as 10 seconds, and then give a control signal to the main motor of the hydraulic station 13. The main motor will drive the hydraulic cylinder 12. After a period of time, such as 3 seconds, a signal will be given to the electromagnetic reversing valve, and the electromagnetic reversing valve will open, and the hydraulic cylinder 12 will move forward to start unloading. The unloading time is set in advance. When the transport compartment is about to be filled with materials, the controller will disconnect the current station electromagnet signal and give a signal to the electromagnet on the other side at the same time. The electromagnet on the other side will be energized and activated, and the hydraulic cylinder 12 will move backward until the backward stroke ends. At this point, the unloading opening and closing is completed.

[0040] Among them, the opening of the unloading plate 7 relies on the power provided by the hydraulic system. The movable frame 72 of the unloading plate 7 is pushed by the oil cylinder, and the movable frame 72 drives the seesaw 74 to move. There is a fixed support rod 75 at the bottom of each unloading plate 7. The bottom of the unloading plate 7 slides on the support rod 75. When the moving distance is greater than half of the total length of the seesaw 74, under the action of the gravity of the material, the seesaw 74 begins to rotate downward around the central axis of one end, and the unloading begins. As the entire movable frame 72 continues to move forward until the hydraulic cylinder 12 completes the stroke, the seesaw 74 rotates downward nearly 90 degrees to the largest opening, the material will lose support, and under the action of gravity, the material will continue to move downward to load the car. When the car is about to be filled, the hydraulic system is manually controlled, the hydraulic rod of the hydraulic cylinder 12 is recovered, and the movable frame 72 is driven to move in the opposite direction, and the unloading plate 7 will also be closed. At this time, all the downward weight of the material acts on the unloading plate 7 again, completing the unloading work. This process can be operated independently by humans or automatically. The container-type seesaw micro-negative pressure unloading device is mainly used in the scene of loading organic fertilizer materials. This unloading device cancels the conical bucket, and the seesaw flips down and the material falls directly. The size of the silo is the size of the unloading opening, and the fertilizer can be loaded quickly. The entire workshop is a closed space, and the exhaust system will remove the dust generated during the loading process, improve the on-site working environment, and reduce pollution to the environment.

[0041] The invented container-type seesaw micro-negative pressure unloading device is mainly used in the scenario of loading organic fertilizer materials. The unloading device eliminates the conical bucket, and the seesaw flips down and the material falls directly. The size of the silo is the same as the size of the unloading opening, so the fertilizer can be loaded quickly. The entire workshop is a closed space, and the exhaust system removes the dust generated during the loading process, thereby improving the on-site working environment and reducing pollution to the environment.
