Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of conveying equipment, specifically relates to a plough coal device hopper. BACKGROUND

[0002] The plough coal device hopper is installed on both sides of the belt conveyor plough coal device when transferring materials to prevent the materials from spilling on the ground and causing dust pollution.

[0003] A rotatable flap is usually installed in the plough coal device hopper to control the opening and closing of the hopper. A limiting structure is also provided in the hopper to limit the excessive turning of the flap at the closed hopper position. The rotating shaft of the flap is connected to a counterweight arm located outside the hopper. The gravity of the counterweight arm keeps the flap in a closed hopper state when the hopper is not conveying materials. When the materials enter the hopper, the gravity and impact force of the materials overcome the gravity of the counterweight arm to make the flap turn to an open hopper state to convey the materials.

[0004] When the materials stop conveying in the hopper, the flap will quickly turn to a closed hopper state under the action of the gravity of the counterweight. The flap will collide violently with the limiting structure in the hopper, which can easily cause the flap to deform and affect the closing effect of the hopper. SUMMARY

[0005] Based on the above description, the utility model provides a plough coal device hopper to solve the problem that when the materials stop conveying in the hopper, the flap will quickly turn to a closed hopper state under the action of the gravity of the counterweight. The flap will collide violently with the limiting structure in the hopper, which can easily cause the flap to deform and affect the closing effect of the hopper.

[0006] The technical solution of the utility model to solve the above technical problem is as follows:

[0007] The present application provides a plough coal device hopper, which adopts the following technical solutions:

[0008] A plough coal device hopper, comprising:

[0009] A hopper body and a flap provided in the hopper body. The flap is connected to the hopper body by a rotating shaft. The rotating shaft can rotate relative to the hopper body around its own axis and has two ends penetrating out of the hopper body. The flap is fixed to the rotating shaft. The flap includes a first position to open the hopper body and a second position to close the hopper body by rotating from the first position in a first rotating direction. The flap is limited by the limiting structure in the hopper body to continue rotating in the first rotating direction when it rotates to the second position in the first rotating direction.

[0010] A counterweight arm is arranged outside the funnel body and connected with the rotating shaft through a connecting structure, the flap is rotated from the second position to the first position against the gravity of the counterweight arm, and the flap is adapted to be rotated in the first rotating direction by the gravity of the counterweight arm.

[0011] A damping device is arranged between the funnel body and the rotating shaft, and the flap is rotated in the first rotating direction against the damping force of the damping device.

[0012] Preferably, the damping device comprises a rotary damper fixed on the funnel body, the rotary axis of the rotary damper is parallel to the rotating shaft axis, the rotary shaft of the rotary damper is connected with the rotating shaft through a transmission structure, and the rotating shaft drives the rotary shaft of the rotary damper to rotate through the transmission structure when the flap is rotated in the first rotating direction.

[0013] Preferably, the transmission structure comprises a first driving gear and a first driven gear which are engaged with each other, the first driving gear is coaxially arranged outside the rotating shaft and connected with the rotating shaft through a one-way transmission member, the rotating shaft drives the first driving gear to rotate synchronously through the one-way transmission member when the flap is rotated in the first rotating direction, and the one-way transmission member disconnects the power transmission between the rotating shaft and the first driving gear when the flap is reversely rotated, and the first driven gear is fixed coaxially with the rotary shaft of the rotary damper.

[0014] Preferably, the one-way transmission member comprises a one-way bearing.

[0015] Preferably, the connecting structure comprises:

[0016] an installation shaft which is parallel to the rotating shaft axis, the installation shaft is rotatably connected with the funnel body, and the counterweight arm is fixed with the installation shaft.

[0017] a second driving gear and a second driven gear which are engaged with each other, the second driving gear is fixed coaxially with the rotating shaft, and the second driven gear is fixed coaxially with the installation shaft.

[0018] Preferably, one end of the counterweight arm is fixed with the installation shaft, and the other end is connected with a counterweight block.

[0019] Preferably, the length direction of the counterweight arm is perpendicular to the installation shaft axis, and the position of the counterweight block in the length direction of the counterweight arm is adjustable.

[0020] Preferably, the limiting structure comprises a limiting block fixed on the inner wall of the funnel body, and the flap is limited to continue to rotate in the first rotating direction when the flap is rotated to the second position and abuts against the limiting block.

[0021] Compared with the prior art, the technical scheme of the present application has at least the following beneficial technical effects:

[0022] 1、The funnel body of the present application does not transport material, and under the gravity of the counterweight arm and the limiting action of the limiting structure, the flap is kept in the second position of closing the funnel body, while transporting material, the impact force and gravity of the material overcome the gravity of the counterweight arm to make the flap rotate from the second position to the first position to open the funnel body, so as to transport the material. By providing a damping device between the rotating shaft and the funnel body, the damping device provides a damping force for the rotation of the flap in the first rotation direction, i.e. the flap needs to overcome the damping force when rotating from the open first position to the closed second position, so that when the funnel stops transporting material, the speed of the flap rotating to the closed funnel state under the gravity of the counterweight arm can be slowed down, thereby avoiding the flap from being damaged by colliding with the limiting structure.

[0023] 2、The present application provides a damping force for the rotation of the flap in the first rotation direction through a rotary damper, which is simple, easy to implement and low in cost. By providing a one-way transmission member between the first driving gear and the rotating shaft, only when the flap rotates from the first position to the second position, the rotating shaft will drive the first driving gear to rotate synchronously, and then the rotary damper will work to generate a damping force under the transmission of the first driven gear, thereby protecting the flap and other structures. When the flap rotates from the second position to the first position, i.e. the flap rotates from the state of closing the funnel body to the state of opening the funnel body, the first driving gear does not rotate with the rotating shaft, and the rotary damper does not work, so that the flap can quickly rotate to open the funnel body to transport material.

[0035] Referring to Figures 1-4 As shown in the drawings, the embodiment of the present application provides a coal plow hopper, which comprises a hopper body 1 and a flap 2 arranged in the hopper body 1, the flap 2 is connected to the hopper body 1 through a rotating shaft 3, the rotating shaft 3 can rotate relative to the hopper body 1 around its own axis and the two ends of the rotating shaft 3 pass through the hopper body 1, the flap 2 is fixed to the rotating shaft 3, the flap 2 comprises a first position for opening the hopper body 1 and a second position for closing the hopper body 1 by rotating from the first position to the first rotating direction, the flap 2 is limited to continue rotating in the first rotating direction by a limiting structure in the hopper body 1 when the flap 2 rotates to the second position in the first rotating direction. In this embodiment, the upper and lower openings of the hopper are shown, the axis of the rotating shaft 3 is horizontal, and the flap 2 is in a horizontal state when it is in the second position.

[0036] Referring to Figures 1-2 As shown in the drawings, the limiting structure comprises a limiting block 4 fixed to the inner wall of the hopper body 1, and the flap 2 is limited to continue rotating in the first rotating direction by abutting against the limiting block 4 when the flap 2 rotates to the second position in the first rotating direction. The flap 2 abuts against the limiting block 4 when it rotates to the second position, so that the flap 2 is kept in a state of closing the hopper body 1, avoiding excessive turning.

[0037] Referring to Figure 1 and Figure 3 Further, as shown in the drawings, a counterweight arm 5 is arranged outside the hopper body 1, the counterweight arm 5 is connected to the rotating shaft 3 through a connecting structure, and the flap 2 overcomes the gravity of the counterweight arm 5 when it rotates from the second position to the first position, and is adapted to rotate in the first rotating direction by using the gravity of the counterweight arm 5.

[0038] Referring to Figure 1 and Figure 3To achieve the above object, the connecting structure is provided with a mounting shaft 6 parallel to the axis of the rotating shaft 3 and a second driving gear 7 and a second driven gear 8 engaged with each other.

When the rotating shaft 3 or the mounting shaft 6 rotates, the second driving gear 7 and the second driven gear 8 are engaged to drive the other to rotate. When the flap 2 rotates from the second position to the first position, the gravity of the counterweight arm 5 is overcome, and when the gravity of the counterweight arm 5 drives the mounting shaft 6 to rotate, the rotating shaft 3 and the flap 2 rotate in the first rotating direction. Thus, the funnel body 1 is automatically closed when not conveying materials by the counterweight arm 5.

[0039] In this embodiment, a bracket 9 is fixedly installed on the outer wall of the funnel body 1 for mounting the mounting shaft 6.

[0040] Referring to Figure 1 and Figure 3 Further, to increase the weight of the counterweight arm 5, one end of the counterweight arm 5 is fixed to the mounting shaft 6 and the other end is connected to a counterweight block 10. Further, the length direction of the counterweight arm 5 is perpendicular to the axis of the mounting shaft 6, and the position of the counterweight block 10 in the length direction of the counterweight arm 5 is adjustable.

[0041] Referring to Figure 1 and Figure 3 Specifically, the counterweight block 10 is sleeved on the counterweight arm 5, and holes are provided on the counterweight block 10 and the counterweight arm 5 for bolts to pass through, so that the counterweight block 10 is fixed on the counterweight arm 5 by passing the bolts through the holes on the counterweight block 10 and the counterweight arm 5 and connecting nuts. There are multiple holes on the counterweight arm 5 and they are distributed along the length direction to adjust the position of the counterweight block 10 on the counterweight arm 5. The position of the counterweight block 10 can be adjusted as needed to change the gravity that needs to be overcome when the flap 2 rotates to the open funnel state, thereby adjusting the opening degree of the funnel.

[0042] Referring to Figure 1 and Figures 3-4 Further, a damping device is provided between the funnel body 1 and the rotating shaft 3, and the flap 2 rotates in the first rotating direction to overcome the damping force of the damping device.

When the flap 2 rotates in the first rotating direction, the rotating shaft 3 drives the rotary shaft of the rotary damper 11 to rotate through the transmission structure.

[0044] Referring to Figures 3-4 As shown in the figure, the transmission structure comprises a first driving gear 12 and a first driven gear 13 which are engaged with each other, the first driving gear 12 is coaxially arranged outside the rotating shaft 3 and connected with the rotating shaft 3 through a one-way transmission member, when the flap 2 rotates in the first rotating direction, the rotating shaft 3 drives the first driving gear 12 to rotate synchronously through the one-way transmission member, and when the flap 2 rotates reversely, the one-way transmission member disconnects the power transmission between the rotating shaft 3 and the first driving gear 12, the first driven gear 13 is fixed coaxially with the rotating shaft of the rotary damper 11. The one-way transmission member is a one-way bearing 14.

[0045] Through the above arrangement, only when the flap 2 rotates from the first position to the second position, the rotating shaft 3 drives the first driving gear 12 to rotate synchronously, and then the rotary damper 11 works to generate damping force under the transmission of the first driven gear 13, thereby protecting the flap 2 and other structures. When the flap 2 rotates from the second position to the first position, i.e. when the flap 2 rotates from the state of closing the funnel body 1 to the state of opening the funnel body 1, the first driving gear 12 does not rotate with the rotating shaft 3, and the rotary damper 11 does not work, so that the flap 2 can rotate quickly to open the funnel body 1 to convey materials.

[0046] The above is only the preferred embodiment of the present application, and is not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
