The terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" and "several" mean two or more, unless otherwise clearly and specifically defined.

[0025] Please also refer to Figures 1 to 5 The present invention provides a feed discharging device, which includes a feed box body 1, a guide plate 4, a vibrating net assembly 5, and a feed pipe 2. The guide plate 4 is arranged in the feed box body 1 along an oblique downward direction, and a feed guide opening is formed between the lower edge of the guide plate 4 and the inner wall of the feed box body 1. The vibrating net assembly 5 is hinged in the feed box body 1 and extends to the bottom of the guide plate 4 to receive and disperse the material. The feed pipe 2 is connected to the bottom of the feed box body 1. A plug chain 3 is provided in the feed pipe 2 and extends axially along the feed pipe 2. The guide plate 4 includes a fixed plate body 41 connected to the inner wall of the feed box body 1 and a movable plate body 42 slidably connected to the fixed plate body 41. The bottom of the fixed plate body 41 is connected to a telescopic driving member 43. The driving end of the telescopic driving member 43 is connected to the movable plate body 42 for driving the movable plate body 42 to slide to adjust the size of the feed guide opening.

[0026] Compared to the prior art, the feed discharging device provided in this embodiment uses an inclined guide plate 4 to guide material toward a vibrating mesh assembly 5. The material, vibrated by the vibrating mesh assembly 5, is evenly dispersed onto the inner bottom wall of the feed bin 1. Finally, a stopper chain 3 running along a feed pipe 2 drives the material for delivery. Furthermore, a telescopic drive member 43 drives a movable plate 42 to extend or retract along a fixed plate 41, adjusting the size of the guide opening and achieving different discharging speeds to meet diverse discharging needs.

[0027] In this embodiment, the upper part of the inner cavity of the material box body 1 is rectangular, which is convenient for the connection between the material guide plate 4 and the vibration net assembly 5. The lower part of the inner cavity of the material box body 1 is concave in an arc shape, which is convenient for the material to gather to the bottom of the material box body 1, ensuring that the plug chain 3 does not leave any dead corners when conveying materials.

[0028] The stopper disc chain 3 includes a chain extending along the axis of the conveying pipe 2 and a series of stopper discs fixed on the chain. The stopper discs are flat circular disc-shaped components, and their outer peripheral walls slide in conjunction with the inner peripheral walls of the conveying pipe 2. When the chain runs in the conveying pipe 2, the stopper discs can effectively push the material to be transported along the axial direction of the conveying pipe 2.

[0029] A maintenance access is provided on the sidewall of the hopper body 1 to facilitate installation and maintenance of the vibrating mesh assembly 5 and the telescopic drive member 43. A hinged cover 12 is provided on the hopper body 1 to seal the access, preventing material from leaking out. Furthermore, a transparent observation window 13 is provided on the cover 12 for observing the material falling into the hopper body 1.

[0030] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 4 and Figure 5 The telescopic driving member 43 is an electric push rod. The fixed end of the telescopic driving member 43 is hingedly connected to the bottom wall of the fixed plate body 41 through a first hinge seat 44, and the driving end of the telescopic driving member 43 is hingedly connected to the bottom wall of the movable plate body 42 through a second hinge seat 45.

[0031] In this embodiment, the telescopic drive member 43 utilizes an electric push rod structure, facilitating automatic control of the telescopic setting of the feed guide plate 4. The electric push rod precisely controls the sliding travel of the movable plate 42, meeting the required accuracy of the feed guide opening. A first hinged seat 44 is welded to the bottom wall of the fixed plate 41, while a second hinged seat 45 is welded to the bottom wall of the movable plate 42. The ends of the electric push rod are hinged to the first and second hinged seats 44, 45, respectively. This not only ensures smooth sliding of the movable plate 42 but also allows the electric push rod to swing freely within a certain range, reducing the requirements for installation precision and effectively adapting to various working environments and changing conditions. Furthermore, the hinged connection can absorb vibration and impact forces generated by the feed discharging device during operation to a certain extent, protecting the electric push rod from damage and improving the overall performance and reliability of the system.

[0032] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 4 and Figure 5 A sliding cavity 411 is provided on the fixed plate body 41, and the movable plate body 42 slides in cooperation with the sliding cavity 411. An avoidance groove 412 communicating with the sliding cavity 411 is provided on the bottom wall of the fixed plate body 41. The avoidance groove 412 extends along the sliding direction of the movable plate body 42 and is used to avoid the second hinge seat 45.

[0033] In this embodiment, a sliding cavity 411 extending toward the interior of the fixed plate body 41 is provided on the lower end surface of the fixed plate body 41, so that the movable plate body 42 can be retracted into the interior of the fixed plate body 41, which helps to increase the sliding stroke of the movable plate body 42 and will not cause positional interference with the first hinge seat 44 on the bottom wall of the fixed plate body 41. By setting the avoidance groove 412, an accommodating space is provided for the second hinge seat 45 to slide with the movable plate body 42, so that the movable plate body 42 can slide smoothly within a larger range. On the other hand, when the movable plate body 42 extends outward, most of the movable plate body 42 can still be located in the sliding cavity 411, that is, the overlapping area between the movable plate body 42 and the fixed plate body 41 is increased, which can ensure the stability of the movable plate body 42 when extending outward, thereby eliminating the need to set a sliding track for the movable plate body 42. At the same time, the above-mentioned setting can first assemble the fixed plate body 41, the movable plate body 42 and the telescopic drive member 43 into one, and then install the whole in the material box body 1, which can not only ensure the overall telescopic performance of the guide plate 4, but also reduce the difficulty of installation.

[0034] Furthermore, a support block can be provided on the inner wall of the material box body 1 to support the protruding end of the movable plate body 42, so as to prevent the driving end of the telescopic driving member 43 from being subjected to the pressure of the movable plate body 42 and the material above for a long time, thereby affecting the service life of the telescopic driving member 43.

[0035] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 2 and Figure 4 The vibration net assembly 5 includes a vibration plate 51 whose upper edge is hinged on an inner wall of the material box body 1, a vibration screen 52 hinged on the lower edge of the vibration plate 51 and located below the material guide plate 4, and a roller 53 rotatably connected to the bottom of the vibration screen 52. The vibration plate 51 is arranged through the material guide opening, and the roller 53 rolls with the plug disc of the plug disc chain 3 and can drive the vibration screen 52 to vibrate under the action of the plug disc chain 3. A vertically extending guide rod 55 is connected to the material box body 1, and the free end of the vibration screen 52 is sleeved on the outer periphery of the guide rod 55.

[0036] In this embodiment, the mutually hinged vibration plate 51 and vibrating screen 52 form an "L"-shaped structure, which in turn forms a "Y"-shaped structure with the inclined guide plate 4. This arrangement causes the material to gradually gather at the angle between the guide plate 4 and the vibration plate 51. The material is then gradually dropped onto the vibrating screen 52 by the vibration of the vibrating screen assembly 5, and then scattered onto the inner bottom wall of the material box body 1, achieving material discharge. During this process, the stopper chain 3 continuously operates along the axial direction of the feed pipe 2. The roller 53 at the bottom of the vibrating screen 52 forms intermittent rolling contact with the series of stoppers on the stopper chain 3, repeatedly lifting and lowering the roller 53, thereby driving the vibrating screen 52 to vibrate up and down. Simultaneously, the stopper chain 3 tends to drive the roller 53 and the vibrating screen 52 axially forward, so the vibrating screen 52 also has a horizontal vibration amplitude. The horizontal displacement of the vibrating screen 52 is achieved by the vertical swinging of the vibration plate 51, whose upper edge is hinged to the material box body 1.

[0037] One side of the vibrating screen 52 is hinged to the lower edge of the vibrating plate 51 as a hinged end, and the other side extends upward at an angle within the material box body 1 as a free end. The roller 53 is located between the hinged end and the free end. A guide rod 55 passes through the free end of the vibrating screen 52 to guide the vibration of the vibrating screen 52 and prevent the vibrating screen 52 from vibrating irregularly and causing it to get stuck.

[0038] A material guide opening is formed between the lower edge of the movable plate 42 and the inner wall of the feed bin body 1. The vibrating plate 51 penetrates the material guide opening and swings within it, allowing material above the material guide plate 4 to fall downward onto the vibrating screen 52 through the gap between the lower edge of the movable plate 42 and the vibrating plate 51. Therefore, the gap between the lower edge of the movable plate 42 and the vibrating plate 51 determines the amount of material discharged. The telescopic drive member 43 drives the movable plate 42 to extend outward to reduce the gap, thereby reducing the material discharge speed, and vice versa, increasing the material discharge speed. When the feed discharge device stops working, the telescopic drive member 43 can drive the movable plate 42 to extend until the lower edge of the movable plate 42 is in contact with the vibrating plate 51, and push the vibrating plate 51 against the inner wall of the feed bin body 1, thereby blocking the material guide opening and preventing the material from continuing to fall.

[0039] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 2 and Figure 3 The free end of the vibrating screen 52 is connected to a guide strip 54 extending horizontally outward. The guide strip 54 is provided with a guide long groove that slides with the guide rod 55. The outer peripheral thread of the guide rod 55 is sleeved with a limit nut 56. The limit nut 56 is located above the guide strip 54 and is used to limit the vibration amplitude of the vibrating screen 52.

[0040] In this embodiment, by providing a guide strip 54 on the outer edge of the vibrating screen 52 and sleeved on the outer periphery of the vertically extending guide rod 55, the guiding effect of the guide rod 55 on the up and down vibration of the vibrating screen 52 is increased. At the same time, the guide long groove provided on the guide strip 54 and the sliding cooperation between the guide long groove and the guide rod 55 can guide the horizontal movement of the guide strip 54, thereby increasing the guiding effect of the guide rod 55 on the horizontal vibration of the vibrating screen 52.

[0041] On this basis, in order to prevent the guide strip 54 from slipping off from above the guide rod 55 due to the excessive vibration amplitude of the vibrating screen 52, a limiting nut 56 is connected to the upper end of the guide rod 55. The outer diameter of the limiting nut 56 is greater than the width of the guide long groove, which can effectively prevent the guide strip 54 from slipping.

[0042] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 3 The guide rod 55 is connected to the inner wall of the material box body 1 through the mounting seat 11, and a rubber gasket 57 is connected above the mounting seat 11 and is sleeved on the outer periphery of the guide rod 55.

[0043] In this embodiment, the mounting base 11 includes a horizontally extending support plate connected to the inner wall of the material box body 1, and two ribs connected between the support plate and the inner wall of the material box body 1. The lower end of the guide rod 55 is connected to the support plate. This arrangement ensures the connection strength between the guide rod 55 and the material box body 1. Furthermore, a rubber gasket 57 is sleeved on the outer periphery of the guide rod 55. On the one hand, it helps to reduce the impact of the vibrating screen 52 on the mounting base 11, and on the other hand, it can effectively reduce the noise generated by the vibrating screen 52 when it vibrates up and down.

[0044] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 2 A plurality of dividing plates 511 extending along the direction of the vibration plate 51 are provided on the side wall of the vibration plate 51 close to the guide plate 4 , and the plurality of dividing plates 511 are arranged at intervals in the horizontal direction.

[0045] In this embodiment, when the feed discharging device is working, materials are accumulated in the space above the material guide plate 4 and the vibration plate 51. The setting of the material dividing plate 511 and the vibration of the vibration plate 51 help the materials to be evenly dispersed in the length direction of the material guide opening before entering the material guide opening, avoiding the problem of uneven material discharge at the material guide opening due to material accumulation and reducing the possibility of material blockage.

[0046] The material separation plate 511 extends along the direction of the vibration plate 51, but does not affect the effect of the lower edge of the movable plate body 42 fitting with the vibration plate 51 to block the material guide opening. Specifically, the material separation plate 511 extends from top to bottom to above the position where the lower edge of the movable plate body 42 fits with the vibration plate 51.

[0047] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 2 and Figure 4 The fixed plate body 41 is rotatably connected to a swing rod 6, which can swing along the top surface of the fixed plate body 41 to move the dispersed materials.

[0048] In this embodiment, the material in the space above the guide plate 4 and the vibrating plate 51 is prone to arching due to long-term accumulation or moisture. The swing arm 6 is arranged with its central axis parallel to the top surface of the fixed plate 41 and can swing along the top surface of the fixed plate 41 to move the material accumulated above the guide plate 4, thereby preventing the material from arching and affecting material discharge.

[0049] Specifically, the upper end of the swing arm 6 is pivotally connected to the fixed plate 41, connected as close to the upper edge of the fixed plate 41 as possible. The lower end of the swing arm 6 extends as far as possible above the extended movable plate 42. This increases the range of the swing arm 6 in moving the material above the guide plate 4, ensuring effective material dispersion. Because the swing arm 6 is a round rod-shaped member, even if the movable plate 42 is retracted, the swing arm 6 extending above the movable plate 42 does not affect material discharge. Furthermore, the swing arm 6 can be connected to an upwardly extending stirring rod to reach into the accumulated material to stir it, thereby enhancing the material agitation effect.

[0050] As a specific embodiment of the feed feeding device provided by the present invention, see Figure 4 and Figure 5The material box body 1 is connected to a driving assembly 7 that drives the swing arm 6 to swing. The driving assembly 7 includes a first gear shaft 71, a second gear shaft 72 and a crank handle 73. The first gear shaft 71 is arranged to penetrate the side wall of the material box body 1 in the horizontal direction and rotate with the material box body 1. The second gear shaft 72 vertically penetrates the fixed plate body 41 and rotates with the fixed plate body 41. The swing arm 6 is connected to the upper end of the second gear shaft 72, and the crank handle 73 is connected to the outer end of the first gear shaft 71. The inner end of the first gear shaft 71 is connected to the first bevel gear 711, and the lower end of the second gear shaft 72 is connected to the second bevel gear 721 that meshes with the first bevel gear 711. The first bevel gear 711 can drive the second bevel gear 721, the second gear shaft 72 and the swing arm 6 to rotate synchronously under the drive of the crank handle 73.

[0051] In this embodiment, rotating the crank 73 drives the first gear shaft 71 to rotate, and the meshing action of the second bevel gear 721 and the first bevel gear 711 drives the second gear shaft 72 to rotate, thereby driving the swing arm 6 to swing. It should be noted that the swing amplitude of the swing arm 6 is limited by the width of the material box body 1. Therefore, in actual use, the rotation amplitude of the crank 73 also needs to be limited. A limit rod can be provided on the outer wall of the material box body 1 to limit the rotation amplitude of the crank 73 to prevent excessive rotation of the crank 73 from causing the swing arm 6 to collide with the inner wall of the material box body 1 and break.

[0052] The first gear shaft 71 is located above the sealing plate 12. In actual use, the falling situation of the material on the vibrating screen 52 can be observed through the observation window 13 on the sealing plate 12. If the material discharge amount is very small under the premise of a large material guide opening, it can be judged that the material above the guide plate 4 is arched. The material can be stirred by turning the crank 73 to ensure that the material falls smoothly.

[0053] Specifically, the swing arm 6 and the second gear shaft 72, as well as the crank handle 73 and the first gear shaft 71, are connected in a detachable manner, such as by setscrews or snap-on connections, to facilitate installation.

[0054] As a specific embodiment of a feed discharging device provided by the present invention, the feed discharging device also includes a controller, a material level detection element electrically connected to the controller is provided in the feed pipe 2, the telescopic drive member 43 is electrically connected to the controller, the material level detection element is used to detect material information in the feed pipe 2, and the controller is used to receive material information and send control instructions to the telescopic drive member 43.

[0055] In this embodiment, the material level detection element can be various sensor elements such as capacitive sensors and optical sensors, and multiple sensor elements can be set in the material delivery pipe 2 to detect in real time whether the material in the material delivery pipe 2 reaches a preset height position, ensuring that the pipe is full when delivering material and empty when emptying material, thereby ensuring the continuous supply of material and avoiding material waste.

[0056] The controller generates control instructions based on the material information detected by the material level detection element, controls the start and stop of the telescopic drive member 43, and then controls the size of the material guide opening by controlling the sliding position of the movable plate body 42, thereby realizing automatic control of the material discharge speed and amount.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
