Description

Technical Field

[0001] The utility model relates to the field of industrial material conveying and loading and unloading, in particular to a unloading device, in particular to a rope-pulling unloading device. Background Art

[0002] In the field of industrial material loading and unloading, the discharge port of the silo is mostly a traditional cylinder-driven flap structure. This structure adopts the lever principle, occupies a large space, and is not suitable for industrial material loading and unloading scenarios with limited vertical space.

[0003] In order to solve the problem of limited operation in the vertical space, the prior art discloses a pull-out plate type automatic unloading hopper, such as Figure 1 As shown, it includes a hopper 1, a plug plate 2, and a cylinder 3. One end of the plug plate 2 is connected to the cylinder 3, and the other end crosses the discharge port of the hopper 1. The plug plate 2 is pulled left and right under the action of the cylinder 3 to open and close the discharge port to achieve the purpose of unloading.

[0004] Although the above technology can solve the problem of limited vertical space operation, there are still the following defects in actual application: after the hopper 1 is filled with materials, the materials are in direct contact with the plug plate 2. During the pulling process, the plug plate 2 has to overcome a large friction force, resulting in unsmooth pulling; at the same time, during the pulling process, some materials with smaller particles will be taken out of the warehouse with the plug plate 2, causing material loss, and some materials with smaller particles will also be stuck in the gap between the plug plate 2 and the discharge port, making it more difficult to pull the plug plate. Utility Model Content

[0005] In view of the above problems, the utility model provides the following technical solutions:

[0006] A discharge device comprises a hopper, a driving device, a pulley, a pull rope and a rope guide, wherein a discharge port is provided at the bottom of the hopper, and a discharge flap is installed at the discharge port; the driving device and the pulley are both arranged outside the hopper, and the pulley is fixedly connected to the hopper; one end of the pull rope is fixedly connected to the discharge flap at the bottom of the hopper, and the other end passes through the interior of the hopper and extends out from the feed port of the hopper, and is fixedly connected to the driving device through the pulley; the part of the pull rope located in the hopper is sleeved with the rope guide.

[0007] Furthermore, the driving device is arranged on a supporting platform supporting the hopper.

[0008] Furthermore, the upper end of the rope guide is exposed from the feed port of the hopper.

[0009] Furthermore, the rope guide is fixed on the inner wall of the hopper.

[0010] Furthermore, the driving device is a cylinder.

[0011] Further, the pulley is a groove wheel.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The unloading flap at the bottom of the hopper is opened or closed by tightening or loosening the pull rope through the joint action of the drive device and the pulley, so as to reduce the friction between the unloading flap and the material, and the action is flexible and the unloading is smooth. At the same time, after the unloading flap is opened, the material can be vertically lowered to the mold mouth without causing material loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 The utility model is a structural schematic diagram of a pull-out plug-in plate type unloading hopper in the prior art.

[0015] Figure 2 It is a structural schematic diagram of the unloading device of the utility model. DETAILED DESCRIPTION

[0016] In order to better understand the structure and function of the utility model, the following is a further description of a discharging device of the utility model in conjunction with the accompanying drawings:

[0017] like Figure 2 As shown, a discharging device includes a hopper 11, a driving device 12, a pulley 13, a pull rope 14, and a rope guide 15.

[0018] The hopper 11 is placed on a support platform 17. A discharge port is provided at the bottom of the hopper 11, and a discharge flap 16 is installed at the discharge port. The drive device 12 and the pulley 13 are both arranged outside the hopper 11. The drive device 12 is also arranged on the support platform 17, and its action is controlled by the position monitoring control unit of the application equipment. The pulley 13 is fixedly connected to the hopper 11. One end of the pull rope 14 is fixedly connected to the discharge flap 16 at the bottom of the hopper 11, and the other end passes through the inside of the hopper 11 and then extends from the feed port of the hopper, passes through the pulley 13 and is fixedly connected to the drive device 12.

[0019] In order to prevent the pull rope 14 from contacting the material in the hopper 11 and thus restricting the movement of the pull rope 14, and to ensure that the pull rope 14 can be freely pulled after the hopper 11 is filled with material, a rope guide 15 is sleeved on the part of the pull rope 14 located in the hopper. The upper end of the rope guide 15 is exposed from the feed port of the hopper 11, which can reduce the probability of the material entering the rope guide 15 during loading, thereby ensuring that the pull rope 14 contacts the material less and can be freely pulled in the rope guide 15.

[0020] Preferably, the rope guide 15 is fixed to the inner wall of the hopper 11 to ensure that the rope guide 15 does not move along with the pulling of the pull rope 14 during the unloading process.

[0021] The driving device 12 is preferably a cylinder, and the pulley 13 is preferably a grooved wheel.

[0022] The use process of the utility model is as follows: when unloading is not required, the unloading flap 16 is in a closed state; when materials enter the hopper 11 and need to be unloaded, the driving device 12 on the support platform 17 is started to loosen the pull rope 14 to open the unloading flap 16, and the materials are unloaded from the hopper 11. After unloading is completed, the pull rope 14 is tightened by the driving device 12 to close the unloading flap 16.
