Detailed Description
In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The utility model can be practiced in many other ways than those herein described and similar modifications can be made by those skilled in the art without departing from the spirit of the utility model, and therefore the utility model is not limited to the practice of the substrate disclosed below.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The following describes the embodiments of the present utility model in further detail with reference to the drawings.
The utility model provides a by fig. 1 to 5, including upper and lower axial jar body 1, both sides are equipped with respectively about axial pivot 2 about in jar body 1, be equipped with in the pivot 2 with jar 1 coaxial interception board 3, curved holding tank 4 has been seted up in jar body 1 in the left side, the holding tank 4 is inserted to pivot 2 left end in and is equipped with gear 5 coaxially, be equipped with in the holding tank 4 be located gear 5 rear and with two gear 5 engaged rack 6, rack 6 can reciprocate, jar body 1 upper end is equipped with outlet duct 7.
In order to enable the rack 6 to move up and down, the rack 6 is in sliding connection with the tank body 1, a stud 8 which is axially up and down and can rotate is arranged in the accommodating groove 4, and the stud 8 is in threaded connection with the rack 6.
In order to rotate the stud 8, a motor 9 positioned below the stud 8 is arranged in the accommodating groove 4, and an output shaft of the motor 9 is fixedly connected with the stud 8 in a coaxial manner.
In order to facilitate feeding, the right end of the tank body 1 is provided with a feeding pipe 10.
