DETAILED DESCRIPTION

[0025] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0026] Please refer to Figure 1 A falling device of a bin feeding device, comprising a first baffle 31, a second baffle 32 and a driving device. The first baffle 31 is fixed on the wall plate 11 of the bin through a support 34, and one end of the first baffle 31 is hingedly arranged on the support 34. The first baffle 31 is located above the lifting belt 20 at the end of the bottom belt 10. The bottom belt 10 transports materials, and the materials fall from the end of the bottom belt 10. The materials fall through the first baffle 31 to the horizontal section of the lifting belt 20. The driving device can drive the first baffle 31 to rotate around the hinge point of the first baffle 31 and the support 34, so that the first baffle 31 is close to or away from the end of the bottom belt 10, so as to change the distance between the first baffle 31 and the end of the bottom belt 10, thereby changing the amount of materials falling from the bottom belt 10, realizing the flow limiting of the falling materials, and reducing the problem of the accumulation of the falling materials on the lifting belt 20.

[0027] Specifically, in the case that the transportation amount of the bottom belt 10 is unchanged, the first baffle 31 is away from the end of the bottom belt 10, the distance between the first baffle 31 and the bottom belt 10 is increased, and the materials on the bottom belt 10 can all or most of them fall through the interval between the first baffle 31 and the bottom belt 10 to the lifting belt 20, at this time, the falling flow is relatively large; the first baffle 31 is close to the end of the bottom belt 10, the distance between the first baffle 31 and the bottom belt 10 is reduced, and a small amount of materials on the bottom belt 10 fall through the interval between the first baffle 31 and the bottom belt 10 to the lifting belt 20, at this time, the falling flow is relatively small, and it is difficult for the materials to form a large pile on the lifting belt 20, thereby reducing the accumulation of the materials on the lifting belt 20. At the same time, the falling of a small amount of materials reduces the dust and debris caused by falling, and reduces the waste of materials. Therefore, the amount of falling materials can be changed by rotating the first baffle 31, and the flow limiting of the falling materials is realized.

[0028] Preferably, the second baffle 32 is connected below the first baffle 31, and the second baffle 32 extends the first baffle 31. When the materials fall on the lifting belt 20, the bottom of the second baffle 32 can sweep the materials falling on the horizontal section of the lifting belt 20, so that the materials are laid flat on the horizontal section of the lifting belt 20, avoiding the materials from gathering in a region of the lifting belt 20 at the same time, and the materials are not easy to roll at the junction of the horizontal section of the lifting belt 20 and the inclined section of the lifting belt 20, which is more convenient for transportation.

[0029] In the present application, the driving device is the cylinder 41, the piston end of the cylinder 41 is connected with the second baffle 32, and the extension and retraction of the piston end of the cylinder 41 drives the second baffle 32 to rotate, thereby driving the first baffle 31 to rotate.

[0030] The first baffle 31 has an initial position, as shown in Figure 1 , and a limit position, as shown in Figure 4 . In the initial position, the central axis of the first baffle 31 and the central axis of the second baffle 32 are collinear and located in the same vertical direction, at this time, the distance between the first baffle 31 and the bottom belt 10 is the closest, and the material falling flow is the smallest; in the limit position, the distance between the first baffle 31 and the bottom belt 10 is the largest, and the material falling flow is the largest. In the present application, when the first baffle 31 is set in the initial position, the piston end of the cylinder 41 is fully extended, and during the process of the first baffle 31 rotating from the initial position to the limit position, the piston end of the cylinder 41 is gradually retracted. The rotation amplitude of the first baffle 31 is adjusted from the minimum flow position to adjust the material falling flow.

[0031] Preferably, the second baffle 32 and the first baffle 31 are hingedly connected to limit the rotation range of the first baffle 31. By driving the first baffle 31 to rotate through the second baffle 32, the hingedly connected second baffle 32 and the first baffle 31 can reduce the rotation range of the first baffle 31 under the action of the same stroke of the cylinder 41. During the process of rotating from the initial position to the limit position, the material falling flow gradually increases from small to large, limiting the rotation range of the first baffle 31 can indirectly limit the maximum falling flow to achieve the flow limiting of the falling amount.

[0032] In order to enable the second baffle 32 to realize the functions of stopping material, spreading material, and scattering material, the driving device directly acts on the second baffle 32 to drive the first baffle 31 to rotate through the second baffle 32. At the same time, in order to avoid the situation that only the second baffle 32 rotates and the first baffle 31 does not rotate, a limiting block 33 for limiting the rotation angle of the second baffle 32 is further arranged on the second baffle 32, and the limiting block 33 is close to the hinged point of the second baffle 32 and the first baffle 31.

[0033] Specifically, the limiting block 33 is arranged on the side end face of the second baffle 32 away from the bottom belt 10, and the limiting block 33 protrudes from the end face of the second baffle 32. The second baffle 32 has a first state, as shown in Figure 1 , and a second state, as shown in Figure 3As shown, in the first state, the axis of the second baffle 32 and the center line of the first baffle 31 are collinear and located in the same vertical direction, that is, when the second baffle 32 is in the first state, the first baffle 31 is located in the initial position at the same time, the driving device acts on the second baffle 32 to make the second baffle 32 rotate around the hinge point of the second baffle 32 and the first baffle 31, the included angle between the second baffle 32 and the first baffle 31 gradually decreases, and the second baffle 32 gradually rotates from the first state to the second state; in the second state, the limiting block 33 is in abutment with the second baffle 32 and the first baffle 31 on both sides, and under the action of the limiting block 33, the rotation angle of the second baffle 32 around the hinge point of the second baffle 32 and the first baffle 31 is limited, and the angle between the second baffle 32 and the first baffle 31 changes from a flat angle to a fixed obtuse angle.

[0034] When the driving device continuously acts on the second baffle 32 in the second state, the second baffle 32 drives the first baffle 31 to rotate around the hinge point of the first baffle 31 and the support 34, the second baffle 32 no longer rotates around the hinge point of the second baffle 32 and the first baffle 31, the included angle between the second baffle 32 and the first baffle 31 is fixed, and the second baffle 32 swings with the rotation of the first baffle 31.

[0035] Specifically, the support 34 is arranged above the horizontal section of the lifting belt 20 at the end of the bottom belt 10, and in the vertical direction, the support 34 is close to the junction of the horizontal section and the inclined section of the lifting belt 20. The cylinder 41 and the bottom belt 10 are located on both sides of the first baffle 31, and the piston end of the cylinder 41 is inclined downward and connected with the second baffle 32.

[0036] The working process is as follows: at the beginning, the piston end of the cylinder 41 is fully extended, the first baffle 31 is located in the initial position, and at the same time, the second baffle 32 is in the first state, the cylinder 41 acts to drive the second baffle 32 to rotate from the first state to the second state and abut against the first baffle, before the second baffle 32 rotates to the second state, only the second baffle 32 rotates, and the first baffle 31 remains in a vertical stationary state; after the second baffle 32 becomes the second state, the cylinder 41 continuously acts, the second baffle 32 is stationary relative to the first baffle 31, the first baffle 31 starts to rotate under the drive of the second baffle 32, the distance between the first baffle 31 and the bottom belt 10 changes, the material flow regulation is realized, and at the same time, the second baffle 32 can sweep the material on the horizontal section of the lifting belt 20, so that the material is laid flat and dispersed on the lifting belt 20, avoiding accumulation.

[0037] Please refer to Figure 2The driving device in the embodiment comprises a cylinder 41 and a position detection device 42 for detecting the action stroke of the cylinder 41, and the piston end of the cylinder 41 is connected with the second baffle 32. Preferably, the cylinder 41 is a double-acting cylinder, which can flexibly adjust the swing direction of the first baffle 31 and the second baffle 32, and has high controllability; the double-acting cylinder is connected with a gas source 46 through a two-position five-way electromagnetic valve 43, the two-position five-way electromagnetic valve 43 controls the extension or retraction of the piston end of the double-acting cylinder, and the piston end of the cylinder 41 acts on the rotation of the second baffle 32 and the first baffle 31 to change the material falling flow.

[0038] Preferably, the gas source 46 is connected with a filtering pressure reducing valve 45 to stabilize the gas pressure, so that the piston end of the cylinder 41 moves stably, and meanwhile, a silencer 44 is installed on the two-position five-way electromagnetic valve 43 to reduce the noise generated due to the change of the gas pressure.

[0039] Further, the two-position five-way electromagnetic valve 43 is electrically connected with the driving motor of the bottom belt 10. The first baffle is in the initial position by default, the piston end of the cylinder 41 is extended to the farthest stroke, when the driving motor drives the bottom belt 10 to move to start transporting the material, the two-position five-way electromagnetic valve 43 is connected to slowly retract the piston end of the cylinder 41, control the rotation of the first baffle 31, gradually increase the material falling amount, until the first baffle 31 is rotated to the appropriate position to adjust the material falling flow. It should be noted that the appropriate position mentioned above should be determined according to the batch and specification of the transported material, and different specifications of the material have different requirements for the quality, and the required material falling flow is also different to reduce the material loss.

[0040] In the present application, a plurality of harrow spikes 21 are uniformly and spacedly arranged on the surface of the lifting belt 20, the material transported by the bottom belt 10 falls onto the horizontal section of the lifting belt 20 and is distributed between the plurality of harrow spikes 21, the harrow spikes 21 can avoid the material from rolling at the connection between the horizontal section and the inclined section when the material moves from the horizontal section to the inclined section, and move the material to the next processing link.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
