Description

Technical Field

[0001] The utility model relates to the technical field of transfer boxes, in particular to the field of unloading doors of transfer boxes, and specifically refers to a hopper with an automatic unloading door. Background Art

[0002] During the production of liquor, the brewing raw materials must go through multiple process steps such as steaming, cooling, and adding koji before they can be put into the pool for fermentation. The transportation of grain, rice husks, grain mash, and wine mash in the liquor brewing workshop is mostly achieved by using equipment such as crane grabs. However, this method of temporary storage and transportation of materials is time-consuming and labor-intensive, resulting in low efficiency in temporary storage and transportation of brewing materials. In order to overcome the shortcomings of traditional transportation methods such as crane grabs, some wines have added some special transportation equipment to the crane, for example, a hopper composed of a frame and an opening and closing component, the frame of which is a rectangle with an opening upward, and the upper and lower sides are transparent, which can effectively improve the temporary storage and transportation efficiency of brewing materials and save transportation time.

[0003] There are also some technical problems with the existing hoppers. For example, the material door of the transfer box is not convenient to open. The opening process requires manual assistance. When closing, a person is also required to stand under the transfer box to close the discharge door, which is time-consuming, labor-intensive, unsafe, and reduces the transfer efficiency. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a hopper with an automatic unloading door, which can automatically open the unloading door of a transfer box. When unloading is completed, the transfer box is placed on the ground and the unloading door can be automatically locked.

[0005] The utility model is realized through the following technical scheme, which provides a hopper with an automatic unloading door, including a box body and a rotating door hinged at the lower end of the box body, a mounting block is fixedly provided on the rotating door, a door bolt extending horizontally is rotatably connected to the mounting block, a door lock mechanism is installed on the box body, the door bolt extends to the door lock mechanism, and also includes a driving mechanism for driving the door lock mechanism to move up and down; the door lock mechanism includes a connecting plate connected to the driving mechanism, the connecting plate is hinged with a transmission handle, the transmission handle is hinged with a rotating plate at one end away from the connecting plate, the rotating plate is rotatably connected to the box body, a limit hook is fixedly connected to the rotating plate, the door bolt extends to the limit hook and is supported on the limit hook.

[0006] The utility model can lock the rotating door on the transfer box by arranging a door lock mechanism. When the transfer box is unloading, the driving mechanism drives the connecting plate to move up and down. In the locked state, the door bolt is supported on the limit hook. When the connecting plate moves down, the connecting plate drives the rotating plate to rotate through the transmission handle. The rotation of the rotating plate drives the limit hook to rotate counterclockwise, so that the limit hook no longer supports the door bolt, and the rotating door opens under the action of gravity.

[0007] As an optimization, a plurality of auxiliary wheels are installed on the revolving door, and the auxiliary wheels are located at one end of the revolving door away from the outer wall of the box body. According to the setting of this optimization scheme, when the unloading is completed, the driving vehicle places the transfer box on the ground, and the auxiliary wheels on the revolving door first touch the ground, and the auxiliary wheels can assist the revolving door to rotate and close.

[0008] As an optimization, the driving mechanism includes a worm gear elevator installed on the box body, the lead screw of the worm gear elevator is connected to a connecting rod, the connecting plate is connected to a top plate, and the connecting rod is fixedly connected to the top plate. The setting of this optimization scheme can make the door lock mechanism run more stably through the worm gear elevator, and the lifting speed of the worm gear elevator is relatively slow, making its operation more stable.

[0009] As an optimization, a plurality of guide tubes are fixedly connected to the box body, and the connecting rod is installed in the guide tube. The arrangement of this optimization scheme can play a guiding role for the connecting rod.

[0010] As an optimization, the front and rear ends of the box body are both provided with door lock mechanisms. The setting of this optimization scheme can limit and lock both sides of the rotating door, making the rotating door more firmly closed.

[0011] As an optimization, a connecting shaft is fixedly connected to the rotating plate, and the limit hook is fixedly arranged on the rotating plate through the connecting shaft, and the connecting shaft is rotatably connected to the box body. In the setting of this optimization scheme, the limit hook is located below the box body, so that the limit hook can conveniently support the door bolt.

[0012] As an optimization, a limit hook is connected to both the left and right sides of the connecting plate. In the setting of this optimization scheme, one limit hook can control one rotating door, and two limit hooks can respectively support a bolt on a rotating door.

[0013] The beneficial effects of the utility model are as follows: when the transfer box is unloading, the driving mechanism drives the connecting plate to move up and down, and in the locked state, the door bolt is supported on the limit hook, and when the connecting plate moves down, the connecting plate drives the rotating plate to rotate through the transmission handle, and the rotation of the rotating plate drives the limit hook to rotate counterclockwise, so that the limit hook no longer supports the door bolt, and the rotating door opens under the action of gravity. When the unloading is completed, the driving vehicle places the transfer box on the ground, and the auxiliary wheels on the rotating door contact the ground first, and the auxiliary wheels can assist the rotating door to rotate and close the door. When the transfer box falls completely, the connection of the door lock mechanism moves up to lock the rotating door. The utility model can complete the automatic opening and closing of the door during the unloading process of the transfer box, which can save the working time of the staff and improve work efficiency.
