The drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0027] Additionally, in the following description, specific details are provided to provide a thorough understanding of the embodiments. However, one skilled in the art will appreciate that the aspects described may be practiced without these specific details.

[0028] Combined with reference Figure 1 , Figure 2 and Figure 3 In the first embodiment of the present application, a material loading and unloading device is provided, including a hopper 1, a cylinder 2 and a connecting rod 3; a door panel 4 is provided at the outlet end of the hopper 1, and specifically, the door panel 4 is provided in the inner cavity of the outlet end of the hopper 1.

[0029] The cross-sectional area of ​​the door panel 4 corresponds to the outlet end of the hopper 1 and can fit tightly with the inner cavity of the hopper 1 to prevent the substances introduced into the hopper 1 from leaking out.

[0030] The connecting rod 3 is arranged outside the hopper 1, one end of which is connected to the door panel 4 and the other end is connected to the oil cylinder 2. Specifically, one end of the connecting rod 3 passes through the outer shell of the hopper 1 and is connected to the door panel 4 in its inner cavity. The oil cylinder 2 is used to drive the connecting rod 3 to rotate, and drive the door panel 4 to rotate and open and close around the connecting rod as the axis.

[0031] A material feeding and discharging device of the present embodiment is provided with a door panel 4 at the outlet end of the hopper 1 for controlling the opening and closing of the outlet end, so as to achieve the purpose of controlling the discharging; at the same time, the cylinder 2 drives the connecting rod 3 to drive the door panel 4 to rotate and open and close, and the rotation angle of the door panel 4 is controlled by controlling the extension and contraction of the cylinder 2, so as to control the feeding amount and the discharging amount of the material feeding and discharging device, and prevent the outlet end of the hopper 1 from being blocked; the device has a simple structure, and only needs the cylinder 2 to drive, so the energy consumption is low.

[0032] The door panel 4 is generally in a closed state, and is tightly fitted with the inner cavity of the hopper 1. At this time, the piston rod of the oil cylinder 2 extends to the maximum stroke, the connecting rod 3 rotates to the maximum angle, and the angle between the door panel 4 and the horizontal plane is the minimum angle. The feed material or domestic waste can enter from the feed port of the hopper 1 and then be stacked on the door panel 4. Specifically, when the rear end needs to unload, the piston rod of the oil cylinder 2 retracts at a certain rate, driving the connecting rod 3 to rotate to the minimum angle, and the connecting rod 3 pulls the door panel 4 to open at a uniform speed until it is half full and fully opened to a state perpendicular to the horizontal plane, and the material or domestic waste in the hopper 1 falls orderly from the outlet end of the hopper 1 into the next process; when the material or domestic waste in the hopper 1 is completely emptied, the piston rod of the oil cylinder 2 extends at a certain rate, driving the connecting rod 3 to rotate to the maximum angle, and the connecting rod 3 pulls the door panel 4 to close slowly until the door panel 4 is tightly fitted with the inner cavity of the hopper 1.

[0033] The feeding and discharging device of this embodiment can drive the connecting rod 3 to rotate at a constant speed through the oil cylinder 2, and then drive the door plate 4 to rotate and open and close at a constant speed with the connecting rod 3 as the axis, so as to achieve the effect of uniform discharge at the outlet end, control the feeding amount and discharging amount of the feeding and discharging device, and prevent the outlet end of the hopper 1 from being blocked. At the same time, each component can be made of high-cost-effective steel, so that the device has strong corrosion resistance and extends the service life of the device.

[0034] The cross-sectional area of ​​the inlet end of the hopper 1 is preferably greater than or equal to the cross-sectional area of ​​the outlet end. Specifically, the angle between the connecting line between the inlet end and the outlet end and the horizontal plane is an acute angle or a right angle, which is convenient for the material or domestic waste introduced into the hopper 1 to move to the outlet end under the action of gravity, and prevents the introduced material or domestic waste from sticking to the side wall of the inner cavity of the hopper 1. In some embodiments, the cross-sectional area of ​​the inlet end of the hopper 1 is preferably greater than the cross-sectional area of ​​the outlet end, and the angle between the connecting line between the inlet end and the outlet end and the horizontal plane is 50-70°, which can better use gravity to allow the introduced material or domestic waste to pass out from the outlet end, and at the same time, effectively increase the size of the inlet end, which is convenient for introducing more material or domestic waste. The inlet end and the outlet end of the hopper 1 can be square, round, rectangular, elliptical, etc.

[0035] Furthermore, the inner cavity of the hopper 1 is made of a material with low friction, corrosion resistance and high strength, which facilitates the movement of the introduced substances or domestic waste to the outlet under the action of gravity, and can also prevent the hopper 1 from being corroded and deformed by pressure.

[0036] When the cross-sectional area of ​​the inlet end of the hopper 1 is preferably larger than the cross-sectional area of ​​the outlet end, a triangular support member may be provided on the side of the inlet end of the hopper to improve the connection stability of adjacent sides of the inner cavity of the hopper 1 .

[0037] Combined with reference Figure 4 As shown, in order to improve the connection stability between the oil cylinder 2 and the connecting rod 3, in some embodiments, a connecting pin 321 is provided on the oil cylinder 2, and the oil cylinder 2 is fixedly connected to the connecting rod 3 via the connecting pin 321.

[0038] In order to further improve the connection stability between the oil cylinder 2 and the connecting rod 3, in some embodiments, the feeding and discharging device also includes a connecting cotter pin 322, which is engaged with the connecting pin shaft 321 to connect the connecting rod 3 and the oil cylinder 2.

[0039] In some embodiments, the feeding and discharging device further includes a bearing 6, and the connecting rod 3 is connected to the door panel 4 via the bearing 6, so as to improve the connection stability between the connecting rod 3 and the door panel 4, so as to control the rotation and opening and closing of the door panel 4.

[0040] In order to better drive the connecting rod 3 to rotate through the oil cylinder 2, and then drive the door panel 4 to move; the oil cylinder 2 may include a first oil cylinder 21 and a second oil cylinder 22, and one end of the door panel 4 is connected to the first oil cylinder 21, and the other end is connected to the second oil cylinder 22. Specifically, the first oil cylinder 21 and the second oil cylinder 22 are symmetrically arranged on the left and right sides of the door panel, and the door panel 4 is connected to the first oil cylinder 21 and the second oil cylinder 22 in the same manner; for example, the door panel 4 is connected to the oil cylinder 2 through the connecting rod 3, and the oil cylinder 2 may be provided with a connecting pin shaft 321, and the feeding and discharging device may include a connecting cotter pin 322 and a bearing 6.

[0041] In some embodiments, the hopper 1 is provided with a travel switch 7, which is used to sense the opening and closing of the door panel 4 and the rotation angle of the connecting rod 3, and sense the discharge of the hopper 1; the travel switch 7 can be placed on one side of the connecting rod 3 and / or the door panel 4. There can be a plurality of travel switches 7, which can fully sense and detect the opening and closing state of the door panel 4 and the rotation angle of the connecting rod 3.

[0042] At the same time, a control component can also be set up to work with the travel switch 7 to automatically control the cylinder 2 after sensing the opening and closing state of the door panel 4 and the rotation angle of the connecting rod 3, thereby achieving the effect of automatically controlling the feeding and discharging state of the feeding and discharging device.

[0043] In order to fix the position of the travel switch 7 , a travel switch base 71 may be provided; the travel switch base 71 is fixedly provided on the hopper 1 and connected to the travel switch 7 .

[0044] A door panel sealing gasket 41 may be provided at the bottom of the hopper 1, which fits with the door panel 4 to ensure the fit of the inner cavity of the hopper 1 when the door panel 4 is closed, prevent the material or domestic garbage in the hopper 1 from seeping out and overflowing, and isolate odors.

[0045] A sensor can also be provided on the outside of the door panel 4 to sense the pressure applied to the door panel 4 when it is closed, thereby determining the feed amount of the hopper 1. The sensor can also be linked to the control component. When the pressure applied to the door panel 4 reaches a certain value, the movement of the cylinder 2 is controlled to drive the door panel 4 to rotate and open, so that the material or domestic waste in the hopper 1 falls into the next process, thereby achieving the purpose of quantitative discharging.

[0046] The feeding and discharging device may further include a cylinder seat 23, which is fixedly connected to the cylinder 2 and is used to fix the position of the cylinder 2 to facilitate the movement of the cylinder 2. Figure 5 A fixed pin shaft 231 may be provided on the cylinder seat 23 for fixing the connection between the cylinder seat 23 and the cylinder 2; more specifically, the feeding and discharging device may also include a fixed cotter pin 232, which is engaged with the fixed pin shaft 231 to improve the connection stability between the cylinder seat 23 and the cylinder 2.

[0047] In some embodiments, in order to isolate the odor of the hopper 1, a material baffle plate 5 is provided at the inlet end of the hopper 1, and the size of the material baffle plate 5 corresponds to the inlet end of the hopper 1. Specifically, in order to improve the close fit between the material baffle plate 5 and the inlet end of the hopper 1, a material baffle plate sealing gasket 51 can be provided on the inlet end of the hopper 1 to fit with the material baffle plate 5.

[0048] A hopper sealing gasket 11 may also be provided at the bottom of the hopper 1 , which can be tightly fitted with subsequent process equipment to prevent substances or domestic garbage falling from the inner cavity of the hopper 1 from seeping out and overflowing from the bottom of the hopper 1 .

[0049] The inner cavity of the hopper 1 may be provided with a limiter, specifically, the limiter may be located below the connection between the door panel 4 and the connecting rod 3, to prevent the door panel 4 in the open state from colliding with the inner cavity of the hopper 1, causing damage to the inner cavity of the hopper 1 or the door panel 4, and also to prevent the feeding and discharging device from generating a large noise during the discharging process. That is, the limiter may be selected as a buffer material, which can alleviate the impact force of the door panel 4, prevent the door panel 4 from colliding with the inner cavity of the hopper 1, and prevent noise.

[0050] In summary, the present application provides a feeding and discharging device, in which a door panel is arranged at the outlet end of the hopper, and the oil cylinder drives the connecting rod to drive the door panel to rotate and open and close. By controlling the extension and contraction of the oil cylinder and thus controlling the rotation angle of the door panel, the feeding amount and the discharging amount of the feeding and discharging device are controlled to prevent the outlet end of the hopper from being blocked; the device has a simple structure, only requires oil cylinder drive, and has low energy consumption. At the same time, the sealing gasket of the baffle plate, the sealing gasket of the door panel, and the sealing gasket of the hopper can be used to improve the airtightness of the feeding and discharging device to prevent the substances or domestic garbage in the hopper from seeping out, overflowing, and odor leakage.
