Description

Technical Field

[0001] The invention relates to the field of material transportation, in particular to a discharge funnel. Background Art

[0002] Belt mechanism is a common material transport device with low transportation cost, safe operation and large load capacity. In practice, in the entire transportation line including the belt mechanism, the transfer or unloading point of the transportation line usually needs to be used in conjunction with a discharge funnel.

[0003] If the material transfer rate from the belt mechanism to the discharge hopper is high, it is easy to cause impact on the discharge hopper, resulting in structural damage to the discharge hopper, such as tearing, breaking or scratching of the discharge hopper belt, deformation of the belt roller of the discharge hopper, etc. In addition, the material entering the discharge hopper is also easy to adhere to the inner wall of the discharge hopper, which not only affects the transfer efficiency of the discharge hopper for materials, but also increases the maintenance burden of the operator. Summary of the invention

[0004] The purpose of the present invention is to provide a discharge funnel, which can improve the use effect of the discharge funnel.

[0005] To achieve the above-mentioned purpose, the present invention provides a discharge funnel, including a funnel shell and a buffer baffle arranged in the funnel shell; the funnel shell is provided with an inlet for the end of the feeding line to extend into; the buffer baffle includes a blocking end for moving when the material impacts and resetting when the material stops impacting; the blocking end is connected to a weight adjacent to the funnel shell; the blocking end drives the weight to hit the funnel shell when resetting.

[0006] Preferably, the top end of the buffer baffle is hinged to the funnel shell, and the bottom end of the buffer baffle is suspended.

[0007] Preferably, the funnel shell is provided with a plurality of hinged portions for allowing the buffer baffle to align with the ends at different intervals.

[0008] Preferably, the weight is located outside the funnel shell.

[0009] Preferably, a connecting rod is provided between the material blocking end and the weight; the material blocking end, the weight and the connecting rod are fixedly connected.

[0010] Preferably, the connecting rod is a horizontally distributed straight rod; the side wall of the funnel shell is provided with a weight hole for the straight rod to pass through.

[0011] Preferably, the straight rod is provided with a plurality of weight mounting holes; all of the weight mounting holes are distributed at intervals along the length direction of the straight rod.

[0012] Preferably, a lower roller is provided at the lower edge of the weight hammer mouth; and the connecting rod is mounted on the lower roller.

[0013] Preferably, the funnel shell comprises a fixed shell plate and a movable shell plate; the top of the movable shell plate is hinged to the fixed shell plate; and the bottom of the movable shell plate is suspended above the lower roller.

[0014] Preferably, the funnel shell is provided with a flexible baffle; the bottom of the flexible baffle is the upper edge of the weight mouth.

[0015] Compared with the above background technology, the discharge funnel provided by the present invention includes a funnel shell, a buffer baffle and a weight.

[0016] The funnel shell is provided with an inlet for the end of the feeding line to extend into, and the material transported by the feeding line enters the funnel shell from the aforementioned inlet; a buffer baffle is arranged in the funnel shell, and the buffer baffle has a blocking end distributed adjacent to the end of the feeding line and used to block the material, and the blocking end moves when the material impacts the buffer baffle and resets when the material stops impacting the buffer baffle; a heavy hammer is connected to the blocking end, and when the material stops impacting the buffer baffle, the blocking end drives the heavy hammer to hit the funnel shell when resetting, causing the funnel shell to vibrate.

[0017] Since no additional power is required when the heavy hammer strikes the funnel shell, but it relies on the original structure and movement relationship of the production line including the feeding line and the unloading funnel, the heavy hammer can be seen to make the funnel shell vibrate by itself.

[0018] The above-mentioned discharge funnel utilizes a buffer baffle to achieve material buffering, ensuring that most of the material can be smoothly transferred and discharged along the inner cavity of the funnel shell, avoiding a large amount of material from adhering to the funnel shell due to impact; the buffer baffle and the heavy hammer are also used to achieve self-vibration of the funnel shell, shaking off the material originally attached to the funnel shell, ensuring the material transfer efficiency of the discharge funnel.

[0019] It can be seen that the unloading funnel can be applied to the material transfer production line of the metal or non-metal industry, which can reduce the impact of the material on the unloading funnel, improve the material transfer efficiency of the unloading funnel, and reduce the maintenance burden of the operator on the unloading funnel.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of the structure of a discharge hopper provided in an embodiment of the present invention; Figure 2 for Figure 1 A local enlarged view at point A; Figure 3 for Figure 1 A partial enlarged view at point B.

[0028] The present invention provides a discharge funnel, comprising a funnel shell 1 provided with a feed inlet and a buffer baffle 2 arranged in the funnel shell 1; the discharge funnel is connected to a feed line through the feed inlet, specifically, the feed line is installed upstream of the discharge funnel, and the end 01 of the feed line extends from the feed inlet of the funnel shell 1, so that the material discharged from the end 01 of the feed line enters the funnel shell 1, and the funnel shell 1 realizes the transfer of the aforementioned material.

[0029] In the discharge funnel, the buffer baffle 2 is in the funnel shell 1 and is arranged close to the end 01 of the feeding line. When the material at the end 01 of the feeding line just leaves the feeding line, it still has a certain speed, so it will fly toward the blocking end of the buffer baffle 2 and impact the blocking end, causing the blocking end to have a certain displacement, such as L1. When the material stops impacting the blocking end, the blocking end will have a certain displacement, such as L2, in the opposite direction of the aforementioned impact direction to achieve reset.

[0030] In order to make the blocking end move relative to the funnel shell 1 under the impact of the material, the buffer baffle 2 used in the present invention can be connected to the funnel shell 1 by suspension, hinge, sliding connection, etc. As for the method of realizing the reset of the blocking end, it includes but is not limited to setting a reset mechanism between the buffer baffle 2 and the funnel shell 1. According to the actual connection method of the buffer baffle 2 and the funnel shell 1, the displacement generated by the blocking end can be the same as the impact direction of the material, or there can be a certain difference from the impact direction of the material.

[0031] In the discharge funnel, the blocking end is connected to a weight 3 which is distributed close to the funnel shell 1. When the material impacts the blocking end and stops impacting the blocking end, the blocking end will produce two displacements in different directions, such as the above-mentioned L1 and L2. Since the weight 3 is connected to the blocking end and close to the funnel shell 1, when the blocking end moves at the above-mentioned L1, the blocking end drives the weight 3 away from the funnel shell 1, and when the blocking end moves at the above-mentioned L2, the blocking end drives the weight 3 to approach and strike the funnel shell 1, causing the funnel shell 1 to vibrate, thereby causing the material attached to the inner wall of the funnel shell 1 to separate from the funnel shell 1.

[0032] The blocking end and the weight 3 can be relatively fixed, for example, the two are positioned and connected by the same rigid structure, and the two can achieve synchronous movement through the rigid structure, including but not limited to synchronous movement in the same direction and synchronous movement in the opposite direction. The blocking end and the weight 3 can be hinged, for example, a hinge or a flexible connector is provided between the weight 3 and the blocking end.

[0033] The above-mentioned weight 3 can be arranged inside the funnel shell 1, for example, the weight 3 is close to the inner wall of the outer shell of the funnel shell 1, or the weight 3 is close to the rib plate inside the funnel shell 1; the weight 3 can also be arranged outside the funnel shell 1, for example, the weight 3 is close to the outer wall of the outer shell of the funnel shell 1.

[0034] In summary, for the materials transferred from the conveying line to the discharge funnel, the discharge funnel provided by the present invention utilizes the buffer baffle 2 to achieve material buffering, ensuring that most of the materials can be smoothly transferred and discharged along the inner cavity of the funnel shell 1, and avoiding a large amount of materials from being attached to the funnel shell 1 due to impact; and the buffer baffle 2 and the heavy hammer 3 are used to achieve the self-vibration of the funnel shell 1, and the self-vibration of the funnel shell 1 is used to shake off the materials attached to the funnel shell 1, thereby ensuring the material transfer efficiency of the discharge funnel and avoiding structural damage to the discharge funnel due to long-term attachment of materials to the discharge funnel.

[0035] The discharge funnel provided by the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0036] In order to simplify the connection between the buffer baffle 2 and the funnel shell 1, in the above-mentioned discharge funnel, the top end of the buffer baffle 2 can be hinged to the funnel shell 1, and the bottom end of the buffer baffle 2 is suspended. Among them, the bottom end of the buffer baffle 2 is the material blocking end.

[0037] When the material has not yet impacted the buffer baffle 2, the buffer baffle 2 naturally hangs in the funnel shell 1; when the material impacts the buffer baffle 2, the material blocking end at the bottom of the buffer baffle 2 is offset under the impact force of the material, so the entire buffer baffle 2 produces a pendulum with its top end as the hinge point; when the material stops impacting the buffer baffle 2, the buffer baffle 2 moves in the opposite direction along the pendulum trajectory of the aforementioned pendulum. It can be seen that in the process of the buffer baffle 2 driving the heavy hammer 3 to strike the funnel shell 1, the buffer baffle 2 performs a single pendulum motion. Compared with setting a mechanism with a reset function between the buffer baffle 2 and the funnel shell 1, the aforementioned installation method has a simpler structure and does not require the introduction of additional power.

[0038] In the above structure, the buffer baffle 2 is usually fixed-axis hinged to the funnel shell 1. The fixed-axis hinge relationship can constrain the movement direction of the buffer baffle 2 and its blocking end, and fully play the role of blocking materials. In addition, a steel wire rope 5 can also be used to connect the funnel shell 1 and the buffer baffle 2 to achieve the hinged connection between the two.

[0039] Taking into account that in actual production, the materials transported by the conveyor line have differences in particle size, speed when leaving the conveyor line, etc. Therefore, in order to take into account the blocking effect of the blocking end on the material and the self-vibration effect of the heavy hammer 3 on the funnel shell 1, the unloading funnel is provided with multiple hinged parts on the funnel shell 1, and the buffer baffles 2 installed on different hinged parts have different distances from the end 01 of the conveyor line.

[0040] For example, the funnel shell 1 is provided with a hinge part I, a hinge part II and a hinge part III, the buffer baffle 2 installed on the hinge part I is spaced at the end 01 of the material conveying line by a spacing S1, the buffer baffle 2 installed on the hinge part II is spaced at the end 01 of the material conveying line by a spacing S2, and the buffer baffle 2 installed on the hinge part III is spaced at the end 01 of the material conveying line by a spacing S3. The aforementioned S1>S2>S3.

[0041] Since the material separated from the end 01 of the conveying line often performs horizontal throwing motion at a horizontal angle or oblique throwing motion at an inclined upward angle, the buffer baffle 2 used to block the material can be installed vertically, and the above-mentioned S1, S2 and S3 can refer to the horizontal distance between the end 01 of the conveying line and the buffer baffle 2.

[0042] When the buffer baffle 2 is installed on the hinge part I, the buffer baffle 2 is suitable for blocking materials with larger particle size or higher speed; when the buffer baffle 2 is installed on the hinge part III, the buffer baffle 2 is suitable for blocking materials with smaller particle size or lower speed.

[0043] The hinged portion I, the hinged portion II and the hinged portion III can all be configured as a bearing seat or a linear limiting groove 131 for pivotally mounting the rotating shaft 6 .

[0044] The above description is only based on the hinge part I, hinge part II and hinge part III as examples. Figure 1 and Figure 2 , Figure 2 Five limiting grooves 131, 1#, 2#, 3#, 4#, and 5#, are shown as hinge parts.

[0045] In a specific embodiment, the weight 3 is arranged outside the funnel shell 1. The material blocking end in the funnel shell 1 and the weight 3 outside the funnel shell 1 are connected through a structure penetrating the funnel shell 1, for example, the material blocking end and the weight 3 are connected through a connecting rod 4. The material blocking end can be fixed to one end of the connecting rod 4, and the weight 3 can be fixed or hinged to the other end of the connecting rod 4 through a hinge shaft II8.

[0046] Whether the connecting rod 4 penetrates the funnel shell 1 can be considered in combination with the shape of the rod body of the connecting rod 4. For example, when the connecting rod 4 is a straight rod, the side wall of the funnel shell 1 is provided with a hammer hole for the straight rod to pass through; when the connecting rod 4 is a folding rod or a curved rod, based on the shape characteristics of the connecting rod 4 itself, the connecting rod 4 can be made to span the side wall of the funnel shell 1 to meet the installation position requirements of the blocking end and the hammer 3 relative to the funnel shell 1. Among them, the straight rod can be specifically a steel bar.

[0047] In the embodiment provided by the present invention, the connecting rod 4 is preferably set as a horizontally distributed straight rod, and one end of the straight rod connected to the weight 3 passes through the weight opening. The weight opening not only meets the installation requirements of the blocking end and the weight 3, but also can constrain the movement direction and even the movement range of the straight rod, so as to better control the movement of the weight 3.

[0048] According to the above records, the buffer baffle 2 and the funnel shell 1 can be installed through multiple hinged parts to adjust the distance between the blocking end and the end 01. Therefore, for the discharge funnel with a weight hole and a straight rod, multiple weight installation holes 41 can be set in the straight rod to adjust the distance between the blocking end and the weight 3, so as to adapt to the buffer baffle 2 installed on different hinged parts.

[0049] For the plurality of weight mounting holes 41 provided on the straight rod, the number of the weight mounting holes 41 may be equal to the number of the hinged parts. All weight mounting holes 41 are spaced apart along the length direction of the straight rod; the spacing between all weight mounting holes 41 may correspond to the spacing between all hinged parts. For example, reference may be made to Figure 1 and Figure 3 , Figure 3Five weight mounting holes 41, 1#, 2#, 3#, 4# and 5#, are shown, among which the 1# hinged part corresponds to the 5# weight mounting hole, and the 2# hinged part corresponds to the 4# weight mounting hole; that is, when the buffer baffle is installed through the 1# hinged part, the weight 3 can be installed in the 5# weight mounting hole, and when the buffer baffle is installed through the 2# hinged part, the weight 3 can be installed in the 4# weight mounting hole, and the rest can be deduced by analogy.

[0050] Since the straight rod is supported by the lower edge of the weight mouth at the weight mouth, in order to reduce the friction between the straight rod and the weight mouth and make the straight rod drive the weight 3 to move smoothly, the unloading funnel is provided with a lower roller 7 at the lower edge of the weight mouth, and the straight rod is mounted on the upper partial wheel surface of the lower roller 7.

[0051] In addition, in the discharge funnel, the funnel shell 1 includes a fixed shell plate 11 and a movable shell plate 12; the top of the movable shell plate 12 is hinged to the fixed shell plate 11 through a hinge shaft 14, and the bottom of the movable shell plate 12 is suspended above the lower roller 7. In other words, the bottom of the movable shell plate 12 is equivalent to the upper edge of the weight mouth.

[0052] Since the movable shell plate 12 can swing around its top, the opening size of the weight opening is not a fixed value, but is flexible and variable within a certain size range. When the connecting rod 4 is tilted due to the swing of the buffer baffle 2, the connecting rod 4 tilted to a certain angle can contact and push the movable shell plate 12, causing the movable shell plate 12 to produce a corresponding deflection, thereby increasing the opening size of the weight opening to adapt to the movement requirements of the connecting rod 4.

[0053] In addition to the movable shell plate 12 and the fixed shell plate 11, the discharge hopper can also use a flexible baffle to adjust the opening size of the hammer mouth. The flexible baffle is arranged above the lower roller 7, and the bottom of the flexible baffle serves as the upper edge of the hammer mouth.

[0054] In addition, an upper roller 9 may be installed at the lower portion of the movable shell plate 12 to prevent the connecting rod 4 from being stuck at the weight mouth.

[0055] The funnel shell 1 used in the present invention is often a shell with a closed top, a discharge port at the bottom, and a feed port at the side wall. For example, a top plate 13 is provided at the top of the funnel shell 1 and is sealed and connected to the side wall. Therefore, the above-mentioned flexible baffle can adopt a structure such as a felt cloth with both flexibility and a certain hardness to minimize the impact on the structural sealing of the funnel shell 1.

[0056] The above is a detailed introduction to the discharge funnel provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
