Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to wine brewing equipment technical field, concretely is a kind of open door hopper. BACKGROUND
[0002] In the brewing of Jiangxiang Baijiu, ground spreading and airing machine has the characteristics of artificial brewing production, so that the vinasse is completed on the ground during the spreading and airing process, which has the advantages of greatly reducing labor intensity and stabilizing liquor quality and liquor yield compared with traditional methods. At the end of the spreading and airing process, the vinasse on the ground needs to be automatically collected and then entered into the next pile-forming process. The traditional method is to manually collect the vinasse on the ground and then pile it up nearby, or to use a mechanical method to pile it up. In this process, the vinasse spread and aired by the machine needs to be manually collected and then grabbed by a shovel and transported to an automatic pile-forming machine for piling. This process causes secondary compression of the vinasse, which not only causes great damage to the material, but also easily causes the vinasse to form clumps, thereby affecting the later saccharification and fermentation.
[0003] In order to minimize the damage to the vinasse, a hopper that can automatically collect the vinasse after spreading and airing in cooperation with the spreading and airing machine is needed, so that the material can be directly lifted and transported to the automatic pile-forming machine for unloading after collection.

[0020] This utility model embodiment provides a double-door hopper, such as Figs. 1-3 As shown, it includes a hopper 1 and two double doors 2.
[0021] like Fig. 3 As shown, the bottom opening of the hopper 1 is an open, arc-shaped discharge port. When the two double doors 2 are combined, their arc is consistent with that of the discharge port at the bottom of the hopper 1. The two double doors 2 are symmetrically arranged at the bottom discharge port of the hopper 1. Under normal conditions, the two double doors 2 can block the discharge port at the bottom of the hopper 1 to prevent the distiller's grains from leaking out. The hopper 1 is equipped with a drive mechanism for driving the two double doors 2 to slide to both sides along the arc direction of the discharge port.
[0022] The drive mechanism includes a motor 11, a reducer 4, a drive shaft 5, two sets of reducers 6, and a driven shaft 7.
[0023] The motor 11, the speed reducer 4 and the driving shaft 5 are arranged on the lateral side of the hopper 1 and are sequentially driven. The speed reducer 4 is a helical gear speed reducer. The model can be R77 helical gear hard tooth surface speed reducer. Other speed reducers with the same function can also be used instead. Specifically, the motor 11 is coaxially connected with the driving helical gear of the speed reducer 4, and the driven helical gear of the speed reducer 4 is fixedly sleeved outside the driving shaft 5.
[0024] The two driven shafts 7 are rotatably arranged on the longitudinal side of the hopper 1 and are connected with the driving shaft 5 through the speed reducer 6, which is a worm gear speed reducer. The model can be NMRV040 worm gear speed reducer. Other speed reducers with the same function can also be used instead. Specifically, the driving shaft 5 and the driven shaft 7 are coaxially connected with the worm gear and the worm of the worm gear speed reducer, respectively.
[0025] Each driven shaft 7 is provided with two groups of worm gear assemblies 8 with opposite rotation driving directions. The worm gear assemblies 8 are non-standard worm gear transmission components. According to the actual size, the two sides of the two opposing doors 2 are coaxially connected with the worm gears of the worm gear assemblies 8 through the driving arms 3. Specifically, the worms of the two worm gear assemblies 8 are coaxially sleeved outside the driven shaft 7, and the outer teeth of the two worms are opposite in rotation direction. The worm gear is pivoted on the hopper 1 or the worm gear housing and is fixed on the hopper 1. One end of the driving arm 3 is coaxially connected to the worm gear. The rotation center of the worm gear is consistent with the center of the arc of the opposing door 2.
[0026] The two opposing doors 2 are provided with universal wheels 9 on the two sides of the bottom. When the two opposing doors 2 are completely closed to the discharge port, the four universal wheels 9 are downward, which facilitates the sliding and transfer of the hopper 1 on the ground.
[0027] The hooks 10 are arranged on the four corners of the top of the hopper 1. The hooks 10 are used for lifting by a travelling crane, which facilitates the transfer of the hopper 1 in space.
[0028] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
